    Die große Bedeutung, die dem Lehrerberuf in der Öffentlichkeit, aber auch in den Bildungswissenschaften für die Qualität von Schule und Unterricht zugemessen wird, stand bislang in deutlichem Kontrast zu Umfang und Intensität der Forschung, die auf den Lehrerberuf gerichtet war. Diese immer wieder beklagte Situation hat sich jedoch gewandelt. Seit etwa einem Jahrzehnt ist eine deutliche Intensivierung und allmähliche Verstetigung der Forschung zum Lehrerberuf zu beobachten. Mit dem vorliegenden Handbuch wird erstmalig eine repräsentative Übersicht über den aktuellen Stand der Forschung zum Lehrerberuf vermittelt. Unter intensiver Berücksichtigung der internationalen Fachdiskussion informieren die 45 Beiträge des Handbuchs über Forschung zu folgenden Themenfeldern: Geschichte des Lehrerberufs, Charakteristika und Rahmenbedingungen des Lehrerberufs, Konzepte der Forschung zum Lehrerberuf, Berufsbiographien von Lehrerinnen und Lehrern, Lehrerbildung, Kognitionen, Emotionen und Kompetenzen von Lehrern...

    The use of natural soils for low-cost removal of precipitated water and slightly polluted waste water has become an issue in legal procedures concerning water management. Although groundwater protection is given high priority, authorities do not have sufficient data on long-term effects and decomposition effects during passage to the soil. The Hydrology Department of Brandenburgische Technische Universitaet Cottbus, on behalf of the Thuringian Environmental Authority, investigated the state of the art of discharge of precipitated water into natural soils. The investigation is the first in a series of which the following effects are expected: Faster results by preliminary assessment of the applicability of the technique envisaged, use of this low-cost technology for waste water treatment in consideration of surface water protection. [German] Die Nutzung natuerlicher Boeden zur kostenguenstigen Beseitigung von Niederschlagswasser aber auch von schwachbelastetem Abwasser ist eine Variante der Abwasserbeseitigung, die zunehmend Antragsgegenstand in wasserrechtlichen Verfahren ist. Der Schutz des Grundwassers ist dabei in besonderem Masse zu beachten. Die Einschaetzung der Eignung dieser Variante ist Behoerden aufgrund unzureichender Aussagen zum Langzeitverhalten und zu Abbaueffekten waehrend der Bodenpassage derzeit nicht moeglich. Durch die THUeRINGER LANDESANSTALT FUeR UMWELT erhielt der Lehrstuhl Wassertechnik der Brandenburgischen Technischen Universitaet Cottbus den Auftrag, im Rahmen einer Literaturstudie, den gegenwaertigen Stand der schadlosen Versickerung von Niederschlagswasser in natuerlichen Boeden aufzuzeigen. Die Literaturrecherche bildet den ersten Schritt einer Untersuchungsreihe, von der folgende Wirkungen erwartet werden: Verfahrensbeschleunigung durch Bewertbarkeit der Eignung der Behandlungsvariante, Nutzung dieser kostenguenstigen Umwelttechnologie zur Behandlung von Abwasser unter Beachtung des Gewaesserschutzes.

    Full Text Available Gender Mainstreaming-Prozesse in Bildungsorganisationen sind geeignet, Wissen darüber zu liefern, wie Gender in Organisationen eingeschrieben ist – in Strukturen, Abläufe und Routinen, in Haltungen und Werte. Darüber gibt die Studie von Seemann jedoch nur zum Teil Auskunft: Der breiten Material-Fülle (Textdokumente und über 40 Expert/-innen-Interviews fehlt an relevanten Stellen die Tiefe: Wie ist für die jeweilige Schule Geschlechtergerechtigkeit definiert? Was ist das Ziel, woran ist die Zielerreichung zu erkennen? Wie werden Konflikte und Widerstände gemanagt? Welche strukturellen Veränderungen können realisiert werden? Ausgeblendet bleibt in Seemanns Untersuchung auch das Doing Gender – das (ReProduzieren von Geschlecherdifferenzen – auf der Ebene von Fachunterricht, Fachkulturen und Didaktik.The processes of gender mainstreaming in educational organizations are appropriate for communicating knowledge about how organizations are inscribed by gender – in their structures, schedule of events and routines, habits, and values. However, Seemann’s study only discloses partial information. At key points, the broad expanse of material (written documents and over 40 expert interviews often lacks depth: How is school gender equity defined for each individual? What is the goal, how can the achievement of that goal be properly identified? How are conflict and dissent managed? Which structural changes can be put into place? Missing in Seemann’s study is also the aspect of doing gender – the (reproduction of gender differences – at the level of subject instruction, subject cultures, and didactics.

    Anejaculation is an uncommon clinical entity that may result from a variety of causes, both organic and psychological. Psychogenic anejaculation is influenced by relationship, behavioral, and psychological factors. We present a clinical case of situational anejaculation, which was managed with a combination of techniques that addressed these factors including changes in masturbatory technique, improved marital communication and quality, and reduction of anxiety using cognitive behavioral techniques. It is suggested that the standard techniques of sex therapy be modified and tailored to manage the specific problems of the individual patient.

  8. The sanitation situation: a case study.

    Ali, S

    1993-10-15

    In India, interviews with and observations of members of 100 households with a latrine were done in the towns of Satna and Khandwa, in Madhya Pradesh State, to examine the sanitation situation, to evaluate the maintenance and performance of the 2 pit pour-flush water seal (PF) latrines of poor households, and to recommend actions to improve the sanitation situation. The upper caste Hindus and Muslims tended to use the PF latrines, while the low caste Hindus tended not to use them. Few dry latrines existed in Satna. More than 75% of the households used the PF latrines, especially in Khandwa. The latrines generally were in disrepair, because more families did not receive either instruction or back-up latrine maintenance. Other apparent reasons for poor maintenance were limited water, illiteracy, limited knowledge of how the PF latrine works, poor construction, excreta adhering to the squatting pan, rain entering the leach pits through the squatting pan causing overflow of the pits contents, clogged outlets and Y-junctions, difficulty in emptying the pits, and collapsed brick drains. Children did not use the latrines in more than 50% of households were the latrines were used. Uncomfortable seats were the reason the children chose to defecate in the open. These findings led the author to recommend that the government adopt laws addressing sanitation in low-cost housing settlements, slums, and other areas. A PF latrine must be constructed for each new building. Dry or bucket latrines must be connected to sewers, if available. Leach pits must be constructed for converting latrines into PF latrines. There should be a ban on new dry or bucket latrines. The government should provide the local authorities the power to enforce these regulations. PF latrines should be free for the poor.

    Full Text Available Seit 2008 wird mit Unterstützung des DAAD an der Universität der Künste in Tirana studienbegleitender Deutschunterricht für Gesangsstudierende angeboten. Ziel vorliegenden Beitrags ist herauszufinden, wie dieser Unterricht bestmöglich an die sprachlichen Bedürfnisse der Gesangsstudierenden angepasst werden kann. Zu diesem Zweck wurden Interviews mit sechs Gesangsstudierenden der Universität der Künste durchgeführt, in denen sowohl nach ihren Motiven für das Lernen des Deutschen gefragt als auch um eine Einschätzung des Deutschunterrichts gebeten wurde. Laut den Ergebnissen war der Hauptgrund des Lernens deutscher Sprache die Musik: Deutsch würde zum Verständnis der Opern führen. Alle Gesangsstudierenden betonten den hohen Bedarf an Aussprache- und Hörverstehenskenntnissen, was für uns Deutschlehrerinnen ein Aufruf zur Entwicklung eigener didaktischer Strategien war. Die Ergebnisse bestätigen die Nützlichkeit unseres Konzepts der Kombination verschiedener didaktisch-methodischer Ansätze im Deutschunterricht für Gesangsstudierende.   The aim of the following study conducted at the University of Fine Arts in Tirana was to cater to the specific needs of vocal studies students studying German as a foreign language. These students undertook communicative DAAD-sponsored German courses, which were the focus of analysis for this study. To this end, interviews with six vocal studies students were conducted in order to determine students’ motivations for learning German and evaluate the usefulness of the German lessons. The choice of German studies was directly linked to the participants’ desire to better understand German-language opera. Furthermore, students emphasized the value of focus on pronunciation and listening comprehension in the lessons. These results have important implications for teachers of German teaching students with highly specific needs, and as such, proved the applicability of our concept of combining

    Full Text Available The aim of this study was to see how contextual factors are expressed, used, and analyzed in data collected in focus group discussions (FGDs. The study includes an assessment of how the methodological reporting of contextual factors might influence and improve the trustworthiness of articles. Articles reporting workplace health, stress, and coping among health professionals were identified in a systematic review and used in the analysis. By using Vicsek's framework of situational factors for analysis of focus group results as a starting point, we found that contextual factors were most frequently described in the method sections and less frequently in the results and discussion sections. Vicsek's framework for the analysis of focus group results covers six contextual and methodological dimensions: interactional factors, personal characteristics of the participants, the moderator, the environment, time factors, and the content of FGDs. We found that the framework does not include a consideration of psychological safety, ethical issues, or organizational information. To deepen the analysis of focus group results, we argue that contextual factors should be analyzed as methodological dimensions and be considered as a sensitizing concept. Credibility, confirmability, dependability, and transferability can be strengthened by using, reporting, and discussing contextual factors in detail. The study contributes to elucidating how reporting of contextual data may enrich the analysis of focus group results and strengthen the trustworthiness. Future research should focus on clear reporting of contextual factors as well as further develop Vicsek's model to enhance reporting accuracy and transferability.

    Effective teamwork in ED resuscitations, including information sharing and situational awareness, could be degraded. Technological cognitive aids can facilitate effective teamwork. This study focused on the design of an ED situation display and pilot test its influence on teamwork and situational awareness during simulated resuscitation scenarios. The display design consisted of a central area showing the critical dynamic parameters of the interventions with an events time-line below it. Static information was placed at the sides of the display. We pilot tested whether the situation display could lead to higher scores on the Clinical Teamwork Scale (CTS), improved scores on a context-specific Situational Awareness Global Assessment Technique (SAGAT) tool, and team communication patterns that reflect teamwork and situational awareness. Resuscitation teamwork, as measured by the CTS, was overall better with the presence of the situation display as compared with no situation display. Team members discussed interventions more with the situation display compared with not having the situation display. Situational awareness was better with the situation display only in the trauma scenario. The situation display could be more effective for certain ED team members and in certain cases. Overall, this pilot study implies that a situation display could facilitate better teamwork and team communication in the resuscitation event. Copyright © 2017 Elsevier Inc. All rights reserved.

    To understand implicit social meanings, the interaction of literal meanings and relevant information in a situational context is important. However, previous studies have not investigated such contextual interactions. Using functional magnetic resonance imaging (fMRI), we investigated cortical mechanisms underlying the processing of implicit meanings, particularly irony, in realistic social situations, focusing on contextual interactions. Healthy subjects were shown pictures depicting daily communicative situations during judgment tasks involving situational appropriateness and literal correctness. The left medial prefrontal cortex showed significantly greater activation during tasks involving situational judgments than during literal judgments. The right temporal pole was activated task-independently during irony-specific processing. The medial orbitofrontal cortex was activated task-dependently during irony processing in situational judgment tasks. These regions have been reported to be involved in theory of mind, and have not been implicated in previous studies on the linguistic processing of implicit meanings. This suggests that the intentional assessment of situational appropriateness for task execution is carried out in the left medial prefrontal cortex, whereas irony is processed in the right temporal pole by assessing situational context automatically, and is judged based on the situational context in the medial orbitofrontal cortex. Our results show that the processing of implicit meanings and irony in contextually rich situations depends on brain mechanisms involved in the "theory of mind," based on processing relevant information in a situational context, and suggest different functions in each region.

    Introduction and Objectives. Nurses, as behavioral models, play a key role in health promotion, and their attitudes towards health promotion highly influence their health and performance. The aim of this study is to explore nursing students' perception of studies in nursing discipline as a situational influence on health promotion. Materials and Methods. This study was conducted using directed content analysis, by means of 20 deep semistructured interviews with nursing students. The participants were selected on purposive sampling. Data was analyzed by the qualitative content analysis method. All interviews were recorded, transcribed, and reviewed, and all codes were extracted and summarized. The codes were subcategorized on the basis of centralization and were categorized after review of subcategories, and finally, a theme was determined. Findings. The theme of nursing discipline's situational influence on nursing students' health promotion was revealed. This theme consisted of “choosing the field,” “unfavorable environmental factors,” “negative impacts of studies in nursing discipline on health,” “positive effects of studies in nursing discipline on health”, “needs,” “attractiveness (aesthetics),” and “coping with negative situational influences in nursing discipline.” Conclusion. The perception of studies in nursing discipline as a health-promoting behavior is under influence of social environment. Considering the importance of the students' positive perception of the existing situation, it is essential to pay attention to their attitudes and perceptions so that they can provide better services to patients.

    This study aimed to test a multilevel mediation model which examined the relationship between the perceived motivational climate created by coaches at team level and motivational regulations towards sport at individual level, as mediated by individual goal orientations. 211 university athletes from 20 teams training in different types of sport completed a battery of instruments that measured the variables included in the model. The statistics significance level was .05. Results of the multilevel mediation model revealed that the task-involving climate at team level positively predicted individual task orientation (γ01 = .77, p .05). The results are in line with previous research that have focused in the study of motivational climate at individual level, but the present study make a novel contribution by providing the perspective of a multilevel mediation model and thereby clarifying the phenomenon at team level.

    Full Text Available Throughout history, women have struggled to gain a place and establish their presence in social life. Mostly, they have continued their life in the position of carrying out family responsibilities. When women want to get involved in the business world, they are facing some problems arising from dogmatic thinking and prejudices, especially among the professions with "male-dominated" judiciary. Maritime profession, one of the oldest professions in the world, was also regarded as a single-gender area until the 20th century. However, in recent years, economical and political changes in the world, equal opportunity in education and incentive works of the International Maritime Organization have led women to work as seafarers. Although female seafarers constitute 2% of the world seafarers, this ratio is higher in developed countries than that of undeveloped or developing countries (URL-1. There is very little information regarding women seafarers in general, including the actual population size. Most of studies focus on passenger ships or cruise ships, not cargo ships (Sohyun, 2010. It is difficult to find relevant studies regarding women seafarers in the world, including in Turkey. In Turkey, women have played an active role and gained an apparent identity in the maritime sector since the 2000s. According to 2015 data, Turkey is ranks the 14th in the world maritime trade with more than 27,6 million deadweight tonnage and manages 1530 vessels (UNCTAD, 2015. In Turkey, many studies related to the employment of seafarers are carried out as in the whole world. However, studies on the employment of women seafarers should be paid more attention. In this study, a questionnaire was carried out with the personnel department managers in Turkish shipping companies. Employment, career, educational status of female seafarers and the general difficulties they face were revealed.

    An epidemiological study has been carried out at the GSF - National Research Center for Environment and Health - between 1948 and 1975, on 1460 ankylosing spondylitis (AS) patients. The aim of the study was to ascertain the late health effects suffered by these patients who had received repeated intravenous injections of the short lived {alpha}-emitter {sup 224}Ra. These patients have been followed together with a control group of 1323 ankylosing spondylitis patients not treated with radioactive drugs and/or X-rays. Causes of death have been ascertained for 842 exposed patients and 861 controls by the end of 2002. In the exposed group there has been a total of 219 malignant diseases and 206 cases among the controls. In particular, we observed 15 cases of leukaemia in the exposure group and 8 cases of leukaemia in the control group. Further subclassification of the leukaemias demonstrated a high increase of myeloid leukaemia in the exposure group (9 cases obs. vs. 2.5 cases exp.), and out of these especially the acute myeloid leukaemias (6 cases observed vs. 1.6 expected), whereas in the control group the observed cases are within the expected range (3 myeloid leukaemias vs. 2.6 cases). Out of these 6 cases of myeloid leukaemia, 3 cases have been observed at doses comparable to those of the currently applied {sup 224}Ra treatment with the preparation SpondylAT {sup registered}, in one case the {sup 224}Ra-dose was the 0.6fold, in another case 1.6fold, whereas in one case the total dose could not be verified exactly. The enhanced leukaemia incidence in our exposed group is in line with results from animal experiments in mice having been injected with bone seeking {alpha}-emitters given at low dose rates. (orig.)

Sie gilt daher als überkomplex und konnte bislang hochschuldidaktisch nicht systematisch transformiert wurden. Zur Rede stehen hier begriffliche Großprojekte wie Gerechtigkeit, Verantwortung, Partizipation, Retinität oder Globalität und Interkulturalität, die als Kristallisationspunkte der Nachhaltigkeitsidee die Grundlagentexte, Positionspapiere und Programme durchziehen. Im Anschluss an die heuristische Studie Globalität und Interkulturalität als integrale Bestandteile beruflicher Bildung für eine nachhaltige Entwicklung (GInE, www.ibw.uni-hamburg.de/GInE wurde ein didaktisches Strukturgitter entworfen, das exemplarische Problemlagen und Dilemmata benennt, so wie Reflexionskategorien für die Hochschuldidaktik in der beruflichen Lehrerbildung zur Diskussion stellt.As a regulative concept, the idea of sustainability implies a number of theorems in the field of humanities. It is regarded as supercomplex and, thus, could not yet be systematically transformed in university didactics. Large scale conceptual terms such as justice, responsibility, participation, retinity, globality, and interculturality are at the core of the discussion – terms which run through basic texts, policy papers, and programmes as focal points of the idea of sustainability. With respect to the heuristic study Globality and Interculturality as Integral Elements of a Professional Education for a Sustainable Development (GInE, www.ibw.uni-hamburg.de/GInE, a didactic framework was designed which not only denotes exemplary problems and dilemmata but also puts up categories of reflection for a university didactics aiming at a professional teacher training.

    Probands with non-bipolar major depressive disorder (MDD) were grouped according to the consistency across episodes with which depression appeared to arise from situational factors. Situational depression showed significant diagnostic stability across the second and third recurrences in a 10-year follow-up. The relatives of recurrently situational probands had higher neuroticism scores, higher lifetime rates of MDD and, when depressed, fewer endogenous symptoms than did the relatives of non-situational probands. This study joins two others in finding an association between stress-related depression and high familial loadings for MDD. It also illustrates the value of diagnostic consistency across episodes as a means of refining groups for the study of diagnostic subtypes.

    Full Text Available Physical inactivity is a major public health concern since it increases individuals’ risk of morbidity and mortality. A subgroup at particular risk is postmenopausal overweight women. The aim of this study was to assess the feasibility and effect of a 12-week ZumBeat dance intervention on cardiorespiratory fitness and psychosocial health. Postmenopausal women with a body mass index (BMI >30 kg/m2 or a waist circumference >94 cm who were not regularly physically active were asked to complete a 12-week ZumBeat dance intervention with instructed and home-based self-training sessions. Before and after the intervention, peak oxygen consumption (VO2peak was assessed on a treadmill; and body composition and several psychometric parameters (including quality of life, sports-related barriers and menopausal symptoms were investigated. Of 17 women (median age: 54 years; median BMI: 30 kg/m2 enrolled in the study, 14 completed the study. There was no apparent change in VO2peak after the 12-week intervention period (average change score: −0.5 mL/kg/min; 95% confidence interval: −1.0, 0.1; but, quality of life had increased, and sports-related barriers and menopausal symptoms had decreased. A 12-week ZumBeat dance intervention may not suffice to increase cardiorespiratory fitness in postmenopausal overweight women, but it increases women’s quality of life.

    Alcohol is one of the leading causes of ill health and premature death in the world. Several studies indicate that working life might influence employees' alcohol consumption and drinking patterns. The aim of this study was to explore work-related drinking situations, with a special focus on answering who initiates and organises these situations. Data were collected through semi-structured group interviews in six Norwegian companies from the private ( n=4) and public sectors ( n=2), employing a total of 3850 employees. The informants ( n=43) were representatives from management and local unions, safety officers, advisers from the social insurance office and human-resource personnel, health, safety and environment personnel, and members from the occupational environment committee. Both qualitative and quantitative content analyses were applied in the analyses of the material. Three different initiators and organisers were discovered: the employer, employees and external organisers. External organisers included customers, suppliers, collaborators, sponsors, subcontractors, different unions and employers' organisations. The employer organised more than half of the situations; external organisers were responsible for more than a quarter. The differences between companies were mostly due to the extent of external organisers. The employer initiates and organises most situations for work-related alcohol use. However, exposure to such situations seems to depend on how many external relations the company has. These aspects should be taken into account when workplace health-promotion initiatives are planned.

  2. Studies on the microbial sulphur cycle in acid ponds in the Niederlausitz mining region in Brandenburg; Untersuchungen zum mikrobiellen Schwefelkreislauf in sauren Tagebau-Restseen der Niederlausitz (Brandenburg)

    Meier, J.

    2001-07-01

    The water quality of the acid ponds in the Niederlausitz brown coal mining region is characterised by pH values below 3 and high concentrations of dissolved iron (up to 10 mM) and sulphate (up to 30 mM). The development of these ponds is determined by the equilibrium that arises between acidifying and alkalinising processes. Acidity develops through weathering and oxidation of iron sulphides in the mining refuse, whereas alkalinity arises through the reduction of iron (III) and sulphate in the pond sediments, a process associated with the oxidation of organic matter. The purpose of the present study was to examine the influence of sulphate reduction and sulphur oxidation on the neutralising potential of the sediments in acid ponds and to characterise and identify the microorganisms involved in these processes. Comparative explorations were performed in two acid waters, namely ponds 111 and 107, and in a neutral water, namely pond B, in a semi-natural area of the Niederlausitz region. [German] Die Wasserqualitaet der sauren Bergbau-Restseen im Braunkohlerevier der Niederlausitz ist durch pH-Werte unter pH 3 und hohe Konzentrationen an geloestem Eisen (bis zu 10 mM) und Sulfat (bis zu 30 mM) gekennzeichnet. Die Entwicklung der Restseen wird durch das Gleichgewicht von aziditaets- und alkalinitaetsbildenden Prozessen bestimmt. Aziditaet entsteht bei der Verwitterung bzw. der Oxidation der Eisensulfide im Kippmassiv, waehrend Alkalinitaet bei der an die Oxidation organischer Substanz gekoppelte Reduktion von Eisen(III) und Sulfat in den Sedimenten der Seen gebildet wird. In der vorliegenden Arbeit wurde der Einfluss der Sulfratreduktion und der Schwefeloxidation auf das Neutralisierungspotenzial der Sedimente der sauren Restseen untersucht sowie die an diesen Prozessen beteiligten Mikroorganismen charakterisiert und identifiziert. Vergleichende Untersuchungen wurden in zwei sauren, Restsee 111 und 107, und in einem neutralen Gewaesser, Restsee B, im naturnahen Bereich

    The thesis deals with a reactive sputter process for the deposition of ITO- films. In contrast to the usual technique, the sputter targets consists of indium-tin-alloy instead of ceramic ITO. All experiments were conducted on an inline coater with 600 mm target-width. The process is stabilized by a control loop based on optical emission detection. The experiments prove, that this control loop guarantees a long term stability of the outcomes of the coating process.Process parameters, that are crucial for the optical and electrical properties of the deposited thin films are identified and studied. Among them are the flow of oxygen and the substrate temperature but also less obvious parameters such as the distance between target and substrate.Througout the work the focus is on the film deposition with pulsed plasmas. Novel bipolar DC pulse- and pulse package generators are employed for the deposition.In order to shed some light onto the influence of certain pulse parameters on the outcome of a particular coating process, a Monte-Carlo-Simulation of the particle flow in pulsed plasmas is developed. This simulation yields the distribution of particles and their respective energies on deliberately placed planes in the process chamber. Particles under investigation are both sputtered species and neutral sputter gas atoms reflected at the target. The results of this simulation provide an explanation for the influence of certain pulse parameters on the outcome of the coating process. The further investigations deal with the influence of the construction of the process chamber on the coating process. For this purpose, locally resolved optical spectra are recorded. In order to analyse these spectra, a novel connected fit algorithm is developed.This algorithm yields the distribution of certain fitparameters on the substrate. Provided the most complex of the discussed parametrizations of the dielectric function are used, these can be crucial properties such as the carrier

    The aim of the performed studies was to develop criteria for the risk assessment of cultivated soils that are contaminated with organic pollutants. Therefore from 1991 to 1994 lysimeter studies with soils which were directly contaminated by adding different PAH and PCB containing materials were carried out. The level of contamination in soils was about 5 mg/kg for benzo(a)parene and 2 mg/kg for PCB 28. Behavior and effects of the added pollutants were measured by analysis of soils (including microbiological methods), plants and percolating water. Besides also the PAH and PCB deposition was determined. During the experiments a continuous disappearance of PAH and PCB was observed due to different reasons (formation of bound residues, mineralisation/metabolisation). Different metabolits of benzo(a)pyrene could be found in the soil in concentrations worth mentioning. The investigated microbiological activities showed partly enduring effects. Biotests in water-extracts of soil did not show any corresponding toxic effect in those soils in which microbiological activities were reduced. This result calls in question the validity of these often ussed biotests in regard to evalute soil quality. The investigated plant species showed large differences with regard to their PAH/PCB contamination. Most accumulation from contaminated soils was found in spinach and lettuce. Metabolits of benzo(a)pyrene in plant material were generally under the detection limits. In the percolate PAH and PCB concentrations were mostly under the detection limit; only few samples had detectable but very low concentrations of these pollutants. As a conclusion of the performed studies it was stated, that if the soil contamination exceeds certain values further investigations with regard to possible plant contaminations are needed. This agrees with formerly statements. (orig.) [Deutsch] Ziel der im Rahmen eines uebergeordneten Verbundprojektes im Labor-, Gefaess- und Erhebungsuntersuchungen

    As the development of Web 2.0, the social media like microblog, blogs and social network have supplied a bunch of information with locations (Volunteered Geographical Information, VGI).Recent years many cases have shown that, if disaster happened, the cyber citizens will get together very quickly and share the disaster information, this results a bunch of volunteered geographical information about disaster situation which is very valuable for disaster response if this VGIs are used efficiently and properly. This project will take typhoon disaster as case study. In this paper, we study the relations between weibo messages and the real typhoon situation, we proposed an analysis framework for mine the relations between weibo messages distribution and physical space. We found that the number of the weibo messages, key words frequency and spatial temporary distribution of the messages have strong relations with the disaster spread in the real world, and this research results can improve our disaster situation awareness in the future. The achievement of the study will give a method for typhoon disaster situation awareness based on VGI from the bottom up, and will locate the disaster spot and evolution quickly which is very important for disaster response and recover.

    Luther, Friedrich

    Eine marktorientierte Unternehmensführung verlangt heute auch ein kritisches Überdenken der Dienstleistung Instandhaltung und deren Schnittstellen zu anderen Unternehmensbereichen. Die Instandhaltung als Dienstleistungsabteilung, welche oft zu Unrecht als nicht "produktiver“ Betriebsbereich angesehen wird, sieht sich deshalb vielen Fragen und Überprüfungen hinsichtlich ihrer Funktion und Effizienz ausgesetzt. In diesem Beitrag soll beispielhaft der Weg einer solchen Instandhaltung vom produktionsintegrierten Bereich in einem mittelständischen Maschinenbau-Unternehmen des Textilmaschinenbaus über den zentralen/dezentralen autonomen Unternehmensbereich zum Profit-Center und letztendlich die Entwicklung zum erfolgreichen externen Dienstleister, eingegliedert in die Piepenbrock Gruppe, dargestellt werden. Dieser Entwicklungsprozess überstreicht einen Zeitraum von etwa 60 Jahren, von 1950 bis heute. Die Betrachtung des gesamten Prozessablaufs, die dabei aufgetretenen Probleme und Hindernisse auf dem Weg zum externen Dienstleister werden analysiert und Aspekte der Zusammenarbeit mit den Betreibern aus Sicht der outgesourcten Instandhaltung aufgezeigt.

    Multi-robot missions are a challenge for operators in terms of workload and situational awareness. These operators have to receive data from the robots, extract information, understand the situation properly, make decisions, generate the adequate commands, and send them to the robots. The consequences of excessive workload and lack of awareness can vary from inefficiencies to accidents. This work focuses on the study of future operator interfaces of multi-robot systems, taking into account relevant issues such as multimodal interactions, immersive devices, predictive capabilities and adaptive displays. Specifically, four interfaces have been designed and developed: a conventional, a predictive conventional, a virtual reality and a predictive virtual reality interface. The four interfaces have been validated by the performance of twenty-four operators that supervised eight multi-robot missions of fire surveillance and extinguishing. The results of the workload and situational awareness tests show that virtual reality improves the situational awareness without increasing the workload of operators, whereas the effects of predictive components are not significant and depend on their implementation.

    Full Text Available Background: Mobile technology permeates every aspect of student lives. The question is whether mobile technology integration can produce desirable effects in the gymnasium. Objective: This preliminary study aimed to investigate the effects of mobile technology integration on student situational interest and physical activity fluctuation in physical education lessons.Methods: Sixth grade students (N = 53 were randomly placed into either an experiment group by class that utilized mobile technology-integrated resources (iPad and applications, or a comparison group that did not utilize technology. Both groups received five identical physical education lessons. Student physical activity was tracked with accelerometers, and they completed the Situational Interest Scale at the end of each lesson. The researchers analyzed the data using descriptive statistics, correlation analysis and multivariate analysis of variance (MANOVA with repeated measures. Results: Students in the experiment group reported significantly lower physical activity and situational interest than their counterparts in the comparison group. A group × lesson interaction suggested that student step/min steadily increased throughout the lessons in the experiment group while remaining relative stable in the comparison group. Conclusions: Mobile technologies such as iPad and applications with no direct physical activity prompt had little effect on increasing physical activity or situational interest in the short term. It is important to consider the classroom dynamics to realistically evaluate the constraints and strengths that mobile technology-integrated physical education lessons may pose in a traditional physical education environment.

Based on attribution theory, internal causality refers to one's aptitudes that cause natural responses in real-life situations, whereas external causality refers to environmental factors, such as experimental conditions, causing such responses. To investigate the issue, we developed a novel approach that assesses causal attribution under experimental conditions. During fMRI scanning, subjects were required to engage in virtual frustrating situations and play the role of protagonists by verbalizing social responses, which were socially adaptive or non-adaptive. After fMRI scanning, the subjects reported their causal attribution index of the psychological reaction to the experimental condition. We performed a correlation analysis between the causal attribution index and brain activity. We hypothesized that the brain region whose activation would have a positive and negative correlation with the self-reported index of the causal attributions would be regarded as neural correlates of internal and external causal attribution of social responses, respectively. We found a significant negative correlation between external causal attribution and neural responses in the right anterior temporal lobe for adaptive social behaviors. This region is involved in the integration of emotional and social information. These results suggest that, particularly in adaptive social behavior, the social demands of frustrating situations, which involve external causality, may be integrated by a neural response in the right anterior temporal lobe.

    Full Text Available Despite the extensive developments in entrepreneurship theory over recent decades, there is a lack of empirical studies examining the influence of owner situationally specific motivation on firm performance focusing on small and medium sized enterprises (SME in New Zealand. The present study attempts to bridge this gap. At the same time, it responds to calls to extend performance measures to include non-financial outcomes by using organisational citizenship behaviours – OCB – as a performance measure. This is based on the observation that OCBs are consistently presented in the literature as a cornerstone of good performance and competitive advantage. The study uses mixed methods, combining surveys and semi-structured interviews. Multiple regression is used to analyse data on entrepreneurial situationally specific motivation (i.e. communicated vision, self-efficacy, and goals provided by a sample of 107 firms. In addition, 107 pairs, each comprising an owner-manager plus a random employee from the same firm, also supplied data on organisational citizenship behaviours. Finally, nine qualitative interviews were conducted with owners to further enhance understanding. The study highlights the statistical significance of the positive relationship of entrepreneurial situationally specific motivation and OCB. This finding suggests that owners who have confidence in their abilities [self-efficacy] and who have communicated their vision [communicated vision] are more likely to encourage in their employees the behaviours that are required in order to function well in their organisations. The implications of this finding for potential future research are discussed.

    Decisions on antibiotic-resistant infection (ARI) prevention in dynamic health care settings should be agile and target the right process at the right time. Health information technologies can aid the recognition of high-risk situations for ARI transmission and timely facilitate operators' situational awareness (SA) in various military and civilian health care locations or transport platforms. High SA is one of the significant predictors of better performance. The objective of this study was to evaluate the impact of the developed health information visualization (VIZ) on the users' SA regarding situations when risks of ARI transmission and exposure are high. The enrolled 19 subjects assessed the proposed VIZ artifacts representing 1 scenario, compared the VIZ effectiveness against the currently employed local methods, and reported their SA (perception and comprehension) with the use of a pre- and post-self-rating questionnaire. The results showed that the VIZ significantly increased SA in the study subjects and revealed the importance of communicating the risk of exposure to ARIs. The VIZ enabled the participants to quickly acknowledge the high-risk individuals (super-spreaders), locations (hot spots), and biosafety (deficient infection prevention). The study concluded that SA-oriented technologies may be promising for promoting better infection prevention practices. Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.

    Children's right to participate in their own healthcare has increasingly become highlighted in national and international research as well as in government regulations. Nevertheless, children's participation in healthcare is unsatisfactorily applied in praxis. There is a growing body of research regarding children's participation, but research from the children's own perspective is scarce. The aim of this study was thus to explore the experiences and preferences for participation in healthcare situations among children with juvenile idiopathic arthritis (JIA) as a foundation for creating strategies to promote their participation in pediatric healthcare. Twenty children, aged 8 to 17 years, with JIA were interviewed individually and in focus groups. In order to increase the children's opportunities to express their own experiences, different interview techniques were used, such as draw-and-tell and role play with dolls. The analysis was conducted with a constructivist grounded theory. The result explores children's perspective of influencing processes promoting their participation in healthcare situations. The core category that emerged was, "Releasing fear and uncertainty opens up for confidence and participation," and the categories related to the core category are, "surrounded by a sense of security and comfort," and "strengthened and supported to become involved." In conclusion, the knowledge gained in this study offers new insights from the perspective of children themselves, and can constitute a valuable contribution to the understanding of necessary conditions for the development of specific interventions that promote participation among children in healthcare situations.

    Providing care for simulated emergency patients may induce considerable acute stress in physicians. However, the acute stress provoked in a real-life emergency room (ER) is not well known. Our aim was to assess acute stress responses in residents during real emergency care and investigate the related personal and situational factors. A cross-sectional observational study was carried out at an emergency department of a tertiary teaching hospital. All second-year internal medicine residents were invited to voluntarily participate in this study. Acute stress markers were assessed at baseline (T1), before residents started their ER shift, and immediately after an emergency situation (T2), using heart rate, systolic, and diastolic blood pressure, salivary α-amylase activity, salivary interleukin-1 β, and the State-Trait Anxiety Inventory (STAI-s and STAI-t). Twenty-four residents were assessed during 40 emergency situations. All stress markers presented a statistically significant increase between T1 and T2. IL-1 β presented the highest percent increase (141.0%, p stress in residents. Resident experience, trait anxiety, and number of emergency procedures were independently associated with acute stress response.

    The unlearning process is complex and sometimes painful in nature. This process usually occurs in social interactions and is very dependent on social contexts and the work environment. To explore the concerns and mental challenges in facing unlearning situations in nurses. This qualitative study using content analysis was conducted in 2013-2015. Participants were 25 people, and research environment was hospitals in Mashhad and Gonabad. The method of data collection was unstructured interview, and sampling was continued until data saturation. First, the recorded interviews were transcribed and reviewed several times. Then open codes were extracted and after reviewing several times, were classified into subcategories based on semantic similarity. Finally, the similar subcategories were put into the main categories semantically. Data analysis led to the emergence of 1,180 initial codes and 8 categories and 3 themes. Our themes were discouraging/encouraging situation, double-edged sword colleagues, and organizational policies paradox, that the central theme of progressive and suppressor organizational climate paradox were derived from them. Exposure to unlearning situations is a complex process of which its adoption and implementation is difficult and challenging. This suggests that supporting nurses and attention to their mental concerns and providing favorable learning conditions is required.

    Full Text Available Vehicle group situation is the status and situation of dynamic permutation which is composed of target vehicle and neighboring traffic entities. It is a concept which is frequently involved in the research of traffic flow theory, especially the active vehicle security. Studying vehicle group situation in depth is of great significance for traffic safety. Three-lane condition was taken as an example; the characteristics of target vehicle and its neighboring vehicles were synthetically considered to restructure the vehicle group situation in this paper. The Gamma distribution theory was used to identify the vehicle group situation when target vehicle arrived at the end of the study area. From the perspective of driver-vehicle feature evolution, the reverse reconstruction method of vehicle group situation in the urban road network was proposed. Results of actual driving, virtual driving, and simulation experiments showed that the model established in this paper was reasonable and feasible.

    2009-01-01

    The aim of this study was to provide a theoretical understanding of nutritional experiences for patients with enteral nutrition (EN) during their stay in the intensive care unit (ICU). It is well known that EN can result in underfeeding for patients in ICUs. How the patients experience their nutritional care during their stay in the ICU remains somewhat unclear. In this study, a grounded theory approach was chosen to conduct and analyse 14 interviews with patients and 21 observations of nutritional care during the patients' stay in an ICU. The core category 'grasping nutrition during the recovery process' was reflected in, and related to, the categories 'facing nutritional changes', 'making sense of the nutritional situation' and 'being involved with nutritional care'. While grasping the nutrition, the patients were emotionally shifting between worry, fear and failure, and relief and hope. Turning points were having the appetite back, getting rid of the feeding tube and regaining a functioning gut. The patients' views of nutritional care during their stay in the ICU may contribute to understanding of how patients make sense of their nutritional changes and how they are involved in their nutritional care. This study shows that grasping the nutrition can be a way to regain some control in a situation where the patients are highly dependent on professional care. Further research is needed to develop this substantive theory in other intensive care settings to support patients' nutritional journey in intensive care. Nurses can promote patients' abilities to grasp their nutritional situation during their recovery process. There is a need to focus not only on the patients' physical needs but also on their emotional and social needs.

    Full Text Available Two experimental studies investigated whether the exposure to cyberbullying situations produces in bullied youth, and in young people in general, higher levels of stress, negative emotions, and attention levels, in comparison to other peer interactions, including bullying. In both studies, participants' physiological activation (Study 1 and 2 and behavioral data (Study 2 were recorded while watching four 1-minute videos representing cyberbullying, face-to-face bullying, prosocial, and neutral interactions. Self-report questionnaires assessed participants' emotional responses to the videos, and victimization. Sixty-one adolescents (65.7% girls participated in Study 1; 35 young adults (60% girls participated in Study 2. Results indicate that cyberbullying causes higher stress and negative emotions than prosocial and neutral peer interactions, but not than bullying. Cyberbullying also elicited higher levels of stress and negative emotions in victims than non-victims, but only for adolescents.

    This study sought to clarify psychosocial and psychiatric differences of suicide-completers dependent on their employment situation. Since December 2007, we have been conducting a Japan-wide study on suicide-completers using a psychological autopsy method, a semi-structured interview by a psychiatrist and a mental health professional including a public health nurse with the closest bereaved. Items questioned included family environment, suicide situation, life history f, labor situation, economic problems, and psychiatric diagnosis according to DSM-IV criteria at the time of death. As of July 2009, we had collected psychosocial and psychiatric information for 46 Japanese suicide cases. More than half of 31 suicide-completers with a job at the time of their death were married men aged 40-59 (mean age 48.1 +/- 12.6). Many had social difficulties such as alcohol-related problems or debt (38.7% and 41.9%, respectively). More than sixty percent of the 15 unemployed suicide-completers were unmarried and aged 20-39 (mean age 43.4 +/- 19.9). The percentage of women in the unemployed suicide-completers was significantly higher than that for women with a job. Although social problems were not confirmed in the unemployed, the prevalence of alcohol use disorders was significantly higher in suicide-completers with ajob than in those who were unemployed. However, the prevalence of schizophrenia was significantly higher in the unemployed. Our findings suggest that to prevent suicide of those with ajob, enhanced mental health support in the workplace and a better understanding of the association between alcohol use disorders and suicide are required. To prevent suicide of those who are unemployed, mental health support for the younger generation, particularly in cases with schizophrenia, is recommended.

    The purpose of this thesis is to provide a theoretical framework and its evaluation methodology of team dynamic task performance of operating team at nuclear power plant under the dynamic and tactical environment such as radiological accident. This thesis suggested a team dynamic task performance evaluation model so called team crystallization model stemmed from Endsely's situation awareness model being comprised of four elements: state, information, organization, and orientation and its quantification methods using system dynamics approach and a communication process model based on a receding horizon control approach. The team crystallization model is a holistic approach for evaluating the team dynamic task performance in conjunction with team situation awareness considering physical system dynamics and team behavioral dynamics for a tactical and dynamic task at nuclear power plant. This model provides a systematic measure to evaluate time-dependent team effectiveness or performance affected by multi-agents such as plant states, communication quality in terms of transferring situation-specific information and strategies for achieving the team task goal at given time, and organizational factors. To demonstrate the applicability of the proposed model and its quantification method, the case study was carried out using the data obtained from a full-scope power plant simulator for 1,000MWe pressurized water reactors with four on-the-job operating groups and one expert group who knows accident sequences. Simulated results team dynamic task performance with reference key plant parameters behavior and team-specific organizational center of gravity and cue-and-response matrix illustrated good symmetry with observed value. The team crystallization model will be useful and effective tool for evaluating team effectiveness in terms of recruiting new operating team for new plant as cost-benefit manner. Also, this model can be utilized as a systematic analysis tool for

    Full Text Available Objective: The aim of the study was to introduce and evaluate the compliance to documentation of situation, background, assessment, recommendation (SBAR form. Methods: Twenty nurses involved in active bedside care were selected by simple random sampling. Use of SBAR was illustrated thru self-instructional module (SIM. Content validity and reliability were established. The situation, background, assessment, recommendation (SBAR form was disseminated for use in a clinical setting during shift handover. A retrospective audit was undertaken at 1 st week (A1 and 16 th week (A2, post introduction of SIM. Nurse′s opinion about the SBAR form was also captured. Results : Majority of nurses were females (65% in the age group 21-30 years (80%. There was a significant association (P = 0.019 between overall audit scores and graduate nurses. Significant improvement (P = 0.043 seen in overall scores between A1 (mean: 23.20 and A2 (mean: 24.26 and also in "Situation" domain (P = 0.045 as compared to other domains. There was only a marginal improvement in documentation related to patient′s allergies and relevant past history (7% while identifying comorbidities decreased by 40%. Only 70% of nurses had documented plan of care. Most (76% of nurses expressed that SBAR form was useful, but 24% nurses felt SBAR documentation was time-consuming. The assessment was easy (53% to document while recommendation was the difficult (53% part. Conclusions: SBAR technique has helped nurses to have a focused and easy communication during transition of care during handover. Importance and relevance of capturing information need to be reinforced. An audit to look for reduced number of incidents related to communication failures is essential for long-term evaluation of patient outcomes. Use of standardized SBAR in nursing practice for bedside shift handover will improve communication between nurses and thus ensure patient safety.

    Complicated and long-lasting wound care of diabetic foot ulcers are moving from specialists in wound care at hospitals towards community nurses without specialist diabetic foot ulcer wound care knowledge. The aim of the study is to elucidate community nurses' professional basis for treating diabetic foot ulcers. A situational case study design was adopted in an archetypical Danish community nursing setting. Experience is a crucial component in the community nurses' professional basis for treating diabetic foot ulcers. Peer-to-peer training is the prevailing way to learn about diabetic foot ulcer, however, this contributes to the risk of low evidence-based practice. Finally, a frequent behaviour among the community nurses is to consult colleagues before treating the diabetic foot ulcers.

    Drawing on a sample of 726 non-clinical adolescents (aged 17-18 years) from high schools in Ankara, Turkey, this paper primarily aims to identify the risk factors related to situational run away behavior. This study was based on an ecological risk factors model and tried to discover the associations for runaways. Run away behavior is one of the problematic behaviors very commonly seen among Turkish adolescents. Regression analyses revealed that predictors for runaway behavior differed due to gender; while, delinquency, sexual intercourse, substance use, parental separation and suicidal ideation were the significant predictors for girl adolescent runaway behaviors, while lack of parental support and depression were the significant predictors for boy adolescent runaway behavior.

  1. The Role of Indigenous Languages in National Development: A Case Study of Nigerian Linguistic Situation

    2013-05-01

    Full Text Available Indigenous languages are indispensable cultural legacies without which all forms of human interactions can be carried out. National development is the development of individuals in a nation. Individuals can develop educationally, socially, politically, economically, and culturally through interaction with government agencies that disseminate policies through various indigenous languages. Development indices such as internal cohesion, integration, unity, economic wellbeing and citizens’ participation in governance are promoted through indigenous languages. Based on these assertions, the author studied the current linguistic situations in Nigeria and found that native languages play fundamental role on issues  such as democracy, technology, metalanguage and linguistic globalization .There are however some challenges in the optimum  utilization of these mother tongues. The major problems being orthographic inadequacy,the multiplicity of minority languages, linguistic desertification and deforestation and  language endangerment.The author then suggests a way forward.

    The key risk analysis technologies for the re-entry of space objects into Earth’s atmosphere are divided into four categories: cataloguing and databases of the re-entry of space objects, lifetime and re-entry trajectory predictions, break-up models after re-entry and multiple debris distribution predictions, and ground impact probability models. In this study, we focused on re- entry prediction, including orbital lifetime assessments, for space situational awareness systems. Re-entry predictions are very difficult and are affected by various sources of uncertainty. In particular, during uncontrolled re-entry, large spacecraft may break into several pieces of debris, and the surviving fragments can be a significant hazard for persons and properties on the ground. In recent years, specific methods and procedures have been developed to provide clear information for predicting and analyzing the re-entry of space objects and for ground-risk assessments. Representative tools include object reentry survival analysis tool (ORSAT) and debris assessment software (DAS) developed by National Aeronautics and Space Administration (NASA), spacecraft atmospheric re-entry and aerothermal break-up (SCARAB) and debris risk assessment and mitigation analysis (DRAMA) developed by European Space Agency (ESA), and semi-analytic tool for end of life analysis (STELA) developed by Centre National d’Etudes Spatiales (CNES). In this study, various surveys of existing re-entry space objects are reviewed, and an efficient re-entry prediction technique is suggested based on STELA, the life-cycle analysis tool for satellites, and DRAMA, a re-entry analysis tool. To verify the proposed method, the re-entry of the Tiangong-1 Space Lab, which is expected to re-enter Earth’s atmosphere shortly, was simulated. Eventually, these results will provide a basis for space situational awareness risk analyses of the re-entry of space objects.

    Radiation therapy is a therapeutic option with curative intent for patients with prostate cancer. Monitoring of prostate-specific antigen (PSA) values is the current standard of care in the follow-up. Imaging is recommended only for symptomatic patients and/or for further therapeutic options. For detection of local recurrence magnetic resonance imaging (MRI) of the prostate is acknowledged as the method of choice. Good results for primary diagnosis were found especially in combination with functional techniques, whereas in recurrent prostate cancer only few studies with heterogeneous study design are available for prostate MRI. Furthermore, changes in different MRI modalities due to radiation therapy have been insufficiently investigated to date. As the initial results were promising prostate MRI and available therapeutic options for detection of local recurrence should be considered in patients with increased PSA. (orig.) [German] Fuer Patienten mit Prostatakarzinom stellt die Radiatio eine potenziell kurative lokale Therapieoption dar. Im Rahmen der Nachsorge nach lokal kurativ intendierter Therapie wird aktuell der Verlauf des PSA-Werts (PSA prostataspezifisches Antigen) kontrolliert, der Einsatz bildgebender Verfahren wird lediglich bei symptomatischen Patienten und/oder zur Planung einer Salvagetherapie empfohlen. Die MRT der Prostata stellt derzeit die Methode der Wahl zur lokalen Rezidivdiagnostik dar.

    Emergency resuscitation of critically ill patients can challenge team communication and situational awareness. Tools facilitating team performance may enhance patient safety. To determine resuscitation team members' perceptions of the Situational Awareness Display's utility. We conducted focus groups with healthcare providers during Situational Awareness Display development. After simulations assessing the display, we conducted debriefs with participants. Dual site tertiary care level 1 trauma centre in Ottawa, Canada. We recruited by email physicians, nurses and respiratory therapist. Situational Awareness Display, a visual cognitive aid that provides key clinical information to enhance resuscitation team communication and situational awareness. Themes emerging from focus groups and simulation debriefs. Three reviewers independently coded and analysed transcripts using content qualitative analysis. We recruited a total of 33 participants in two focus groups (n = 20) and six simulation debriefs with three 4-5 member teams (n = 13). Majority of participants (10/13) strongly endorsed the Situational Awareness Display's utility in simulation (very or extremely useful). Focus groups and debrief themes included improved perception of patient data, comprehension of context and ability to project to future decisions. Participants described potentially positive and negative impacts on patient safety and positive impacts on provider performance and team communication. Participants expressed a need for easy data entry incorporated into clinical workflow and training on how to use the display. Emergency resuscitation team participants felt the Situational Awareness Display has potential to improve provider performance, team communication and situational awareness, ultimately enhancing quality of care.

    In this forum, I take a learning sciences perspective to examine the paper by Bellocchi, Ritchie, Tobin, Sandhu and Sandhu ( Cultural Studies of Science Education, doi: 10.1007/s11422-013-9526-3 , 2013) titled "Examining emotional climate of preservice science teacher education." I characterize their approach as a social cultural and situative perspective of studying emotions in teaching and learning. Such an approach overcomes the limitations of examining emotions as individual psychological constructs, but it also incurs other methodological challenges. I suggest an alternative approach of examining the individual's emotions, as well as their aggregates as a group measure. This approach allows us to study variations in emotional outcomes at an individual level or at a group level. I also suggest examining interplay of emotions with other aspects of learning outcomes, for example, cognitive learning outcomes. Finally, I suggest studying development of meta-emotional knowledge among teachers as another fertile area of research that could benefit the teachers in their classroom practices.

    Full Text Available This study was conducted as a retrospective analysis of Northern Foods Plc., once a major player in FTSE 350 Food Sector, to evaluate its financial situation over a five year period. The ex post factor research design was used for this study. Annual reports and databases on Northern Foods Plc., and Associated British Foods Plc., were used to perform a series of ratio analyses. The results revealed that Northern Foods Plc.’s performance has been declining as evidenced in the profitability ratios calculated. Also, financial strength was weak and working capital has not been effectively managed, hence affecting its cash and profit generation potentials. The company was limited in its ability to grow and expand as it needed to regularly fund its pension deficit, and finance its high levels of debt. The study concludes that Northern Foods was not in a very strong financial position, yet it was not making the required investments to improve, hence its takeover though this paper will not rule out non-financial issues. Furthermore, the study prescribed five generic points to improve the financial health of any organisation.

    As communities grow, greater demands are placed on water supplies, wastewater services, and the electricity needed to power the growing water services infrastructure. Water is also a critical resource for thermoelectric power plants. Future population growth in the United States is therefore expected to heighten competition for water resources. Many parts of the United States with increasing water stresses also have significant wind energy resources. Wind power is the fastest-growing electric generation source in the United States and is decreasing in cost to be competitive with thermoelectric generation. Wind energy can offer communities in water-stressed areas the option of economically meeting increasing energy needs without increasing demands on valuable water resources. Wind energy can also provide targeted energy production to serve critical local water-system needs. The research presented in this report describes a systematic assessment of the potential for wind power to support water utility operation, with the objective to identify promising technical applications and water utility case study opportunities. The first section describes the current situation that municipal providers face with respect to energy and water. The second section describes the progress that wind technologies have made in recent years to become a cost-effective electricity source. The third section describes the analysis employed to assess potential for wind power in support of water service providers, as well as two case studies. The report concludes with results and recommendations.

    As global competition intensifies, research and development (R & D) organizations need to enhance their strategic management in order to become goal-directed communities for innovation and allocate their resources consistent with their overall R & D strategy. The world pharmaceutical market has undergone fast, unprecedented, tremendous and complex changes in the last several years. The pharmaceutical industry is today still one of the most inventive, innovative and lucrative of the so-called "high-tech" industries. This industry serves a dual role in modern society. On one hand, it is a growing industry, and its output makes a direct contribution to gross domestic product (GDP). On the other side, drugs, this industry's major output, are an input in the production of good health. The purpose of this study is to evaluate R & D activities of pharmaceutical companies, and also to highlight critical factors which have influential effect on results of these activities. To run this study a valid questionnaire based on literature review and experts' opinion was designed and delivered to 11 pharmaceutical companies. Empirical data show there is not acceptable situations considering of the factors that should be taken in to account by managers including; management commitment, human resource management, information technology and financial management. Furthermore, we concluded some interesting results related to different aspects of R & D management. In conclusion, managers must be aware about their performance in R & D activities, accordingly they will able to take a comprehensive policy in both national and within the company.

    Although peer-based work is encouraged by theories in developmental psychology and although classroom interventions suggest it is effective, there are grounds for recognising that young pupils find collaborative learning hard to sustain. Discontinuities in collaborative skill during development have been suggested as one interpretation. Theory and research have neglected situational continuities that the teacher may provide in management of formal and informal collaborations. This experimental study, with the collaboration of the science faculty in one urban secondary college, investigated the effect of two role attribution strategies on communication in peer groups of different gender composition in three parallel Year 8 science classes. The group were set a problem that required them to design an experiment to compare the thermal insulating properties of two different materials. This presents the data collected and key findings, and reviews the findings from previous parallel studies that have employed the same research design in different school settings. The results confirm the effectiveness of social role attribution strategies in teacher management of communication in peer-based work.

Methods: A feasibility study design incorporating quantitative and qualitative components was used. The study was conducted in three mental health inpatient units at three hospitals in southern Finland. Quantitative data were used to explore demand (nurses’ actual use of the DASA, limited efficacy (predictive validity, and acceptability (measured through patients’ participation in the project. Qualitative data were collected to enhance the understanding of acceptability by describing patients’ perceptions of the strengths and weaknesses of the DASA. Results: Nurses used the DASA for most patient assessments. The predictive validity of the DASA was outstanding or excellent, depending on the type of aggression predicted, although the patient recruitment ratio was low. Patients reported both strengths and weaknesses of the DASA, providing complementary information regarding the instrument’s acceptability and clinical application. Conclusion: The DASA accurately predicts inpatient aggression. The patients’ preferences and concerns regarding risk assessment have been noted.

    Full Text Available This paper investigates the syntactic behaviour of adverbial clauses in contemporary German and Italian. It focuses on three main questions: (i How many degrees of syntactic integration of adverbial clauses are there to be distinguished by an adequate grammatical description of the two languages? (ii Which linear and hierarchical positions in the structure of the matrix sentence can be occupied by adverbial clauses? (iii Which is the empirical distribution of adverbial clauses introduced by the conjunctions als, während, wenn, obwohl and weil in German, as well as quando, mentre, se, sebbene and perché in Italian? Responding to question (i, a distinction is drawn between strongly integrated, weakly integrated and syntactically disintegrated adverbial clauses. There are further degrees on the gradient of syntactic integration, which are not examined in this paper. Responding to question (ii, eight classes of structural positions in the matrix sentence are identified that can be occupied by adverbial clauses. Five of them are positions of syntactic integration, three are positions of disintegration. Responding to question (iii, the distribution of the ten classes of adverbial clauses is described on the basis of a corpus of internet data. Strongly integrated, weakly integrated and disintegrated adverbial clauses show clearly different distributions within the structure of the matrix sentence. Also the semantic classes of adverbial clauses (temporal, adversative, conditional, concessive, causal are distributed differently.

    Human-robot interactions are often affected by error situations that are caused by either the robot or the human. Therefore, robots would profit from the ability to recognize when error situations occur. We investigated the verbal and non-verbal social signals that humans show when error situations occur in human-robot interaction experiments. For that, we analyzed 201 videos of five human-robot interaction user studies with varying tasks from four independent projects. The analysis shows that there are two types of error situations: social norm violations and technical failures. Social norm violations are situations in which the robot does not adhere to the underlying social script of the interaction. Technical failures are caused by technical shortcomings of the robot. The results of the video analysis show that the study participants use many head movements and very few gestures, but they often smile, when in an error situation with the robot. Another result is that the participants sometimes stop moving at the beginning of error situations. We also found that the participants talked more in the case of social norm violations and less during technical failures. Finally, the participants use fewer non-verbal social signals (for example smiling, nodding, and head shaking), when they are interacting with the robot alone and no experimenter or other human is present. The results suggest that participants do not see the robot as a social interaction partner with comparable communication skills. Our findings have implications for builders and evaluators of human-robot interaction systems. The builders need to consider including modules for recognition and classification of head movements to the robot input channels. The evaluators need to make sure that the presence of an experimenter does not skew the results of their user studies.

    When a patient safety incident (PSI) occurs, not only the patient, but also the involved health professional can suffer. This study focused on this so-called "second victim" of a patient safety incident and aimed to examine: (1) experienced symptoms in the aftermath of a patient safety incident; (2) applied coping strategies; (3) the received versus needed support and (4) the aspects that influenced whether one becomes a second victim. Thirty-one in-depth interviews were performed with physicians, nurses and midwives who have been involved in a patient safety incident. The symptoms were categorized under personal and professional impact. Both problem focused and emotion focused coping strategies were used in the aftermath of a PSI. Problem focused strategies such as performing a root cause analysis and the opportunity to learn from what happened were the most appreciated, but negative emotional responses such as repression and flight were common. Support from colleagues and supervisors who were involved in the same event, peer supporters or professional experts were the most needed. A few individuals described emotional support from the healthcare institution as unwanted. Rendered support was largely dependent on the organizational culture, a stigma remained among healthcare professionals to openly discuss patient safety incidents. Three aspects influenced the extent to which a healthcare professional became a second victim: personal, situational and organizational aspects. These findings indicated that a multifactorial approach including individual and emotional support to second victims is crucial. Copyright © 2016 SECA. Publicado por Elsevier España, S.L.U.

    Chronic orofacial pain is a complex condition with consequences that affect daily living. The aim was to analyse nonspecific chronic orofacial pain patients'experiences of everyday life situations, using a qualitative approach. Eleven women and 3 men (21 to 77years) were selected through a purposive sampling among chronic orofacial pain patients referred to the Faculty of Odontology's orofacial pain unit at Malmö University, Malmö Sweden. All selected subjects agreed to participate. Data were obtained via two thematic in-depth interviews with each subject. Interviews were taped and transcribed verbatim.Text dealing with the subjects' daily experiences was identified in all interviews and analysed using qualitative content analysis that focused on manifest content. In everyday life situations, the analysis of nonspecific chronic orofacial pain patients' narrations exposed a fear of conflict, of personal weakness, and of the intangible; they also exposed self-blame and avoidance of fear-triggering situations. Eight of the 14 subjects did not spontaneously mention any situation in which they were content during daily living. When the patients spoke about everyday life experiences, the main finding was that unpleasant emotions dominated the subjects'experiences. In conclusion, the chronic orofacial pain condition cannot be understood as an isolated phenomenon; it must be considered in rela- tion to the person who is suffering from the condition.

    To assess the impact of the Regional experimental accompanying nutrition and breast-feeding for pregnant women (PRENAP) 75 social device on the duration of postpartum hospitalization and breast-feeding for pregnant women in precarious situation. A retrospective observational study took place between November 2013 and May 2015 in a type III Parisian maternity. Comparison of sociodemographic, perinatal and postpartum characteristics of women in precarious situations (no stable housing and no social care or universal medical coverage or state medical aid) was done according to whether they were included in the system PRENAP or not. Over the study period, 344 (4.6%) women in precarious situations gave birth in this maternity. Among these women, the women included in the PRENAP system were more frequently in a very unfavorable social situation than those who were not included. The inclusion in the PRENAP device did not reduce the hospitalization in post-partum. Breast-feeding was chosen more frequently by the women included in the PRENAP device. The PRENAP device seems to favor the use of breast-feeding, but is not associated with a diminution of the hospitalization time in post-partum. This social device, which seems to be beneficial in terms of social and medical support for women in precarious situations, deserves to be evaluated prospectively.

  9. EXPERIMENTAL STUDIES ON DIFFICULTY OF EVACUATION FROM UNDERGROUND SPACES UNDER INUNDATED SITUATIONS USING REAL SCALE MODELS

    Baba, Yasuyuki; Ishigaki, Taisuke; Toda, Keiichi; Nakagawa, Hajime

    Many urbanized cities in Japan are located in alluvial plains, and the vulnerability of urbanized areas to flood disaster is highlighted by flood attacks due to heavy rain fall or typhoons. Underground spaces located in the urbanized area are flood-prone areas, and the intrusion of flood watar into underground space inflicted severe damages on urban functions and infrastructures. In a similar way, low-lying areas like "bowl-shaped" depression and underpasses under highway and railroad bridges are also prone to floods. The underpasses are common sites of accidents of submerged vehicles, and severe damage including human damage occasionally occurs under flooding conditions. To reduce the damage due to inundation in underground space, needless to say, early evacuation is one of the most important countermeasures. This paper shows some experimental results of evacuation tests from underground spaces under inundated situations. The difficulities of the evacuation from underground space has been investigated by using real scale models (door, staircase and vehicle), and the limit for safety evacuation is discussed. From the results, it is found that water depth of 0.3 - 0.4m would be a critical situation for the evacuation from underground space through staircases and door and that 0.7 - 0.8m deep on the ground would be also a critical situation for safety evacuation though the doors of the vehicle. These criteria have some possibility to vary according to different inundated situations, and they are also influenced by the individual variation like the difference of physical strength. This means that these criteria requires cautious stance to use although they show a sort of an index of the limitation for saftty evacuation from underground space.

    Full Text Available Stressful situations of plants can be caused by a lack of nutrients; mechanical damages; diseases; low or high temperatures; lack of illumination; insufficient or excess humidity of the soil; soil salinization; soil pollution by oil products or heavy metals; the increased acidity of the soil; use of pesticides, herbicides, insecticides, etc.At early stages it is often difficult to detect seemingly that the plants are in stressful situations caused by adverse external factors. However, the fluorescent analysis potentially allows detection of the stressful situations of plants by deformation of laser-induced fluorescence spectra. The paper conducts experimental investigations to learn the capabilities of the laser fluorescent method to monitor plant situations at 532nm wavelength of fluorescence excitation in the stressful situations induced by improper watering (at excess of moisture in the soil and at a lack of moisture.Researches of fluorescence spectra have been conducted using a created laboratory installation. As a source to excite fluorescence radiation the second harmonica of YAG:Nd laser is used. The subsystem to record fluorescence radiation is designed using a polychromator and a highly sensitive matrix detector with the amplifier of brightness.Experimental investigations have been conducted for fast-growing and unpretentious species of plants, namely different sorts of salad.Experimental studies of laser-induced fluorescence spectra of plants for 532nm excitement wavelength show that the impact of stressful factors on a plant due to the improper watering, significantly distorts a fluorescence spectrum of plants. Influence of a stressful factor can be shown as a changing profile of a fluorescence spectrum (an identifying factor, here, is a relationship of fluorescence intensities at two wavelengths, namely 685 nm and 740 nm or (and as a changing level of fluorescence that can be the basis for the laser method for monitoring the plant

    Occupational accidents constitute a substantial health and economic burden for societies around the world and a variety of factors determine the frequency of accidents at work. The aim of this paper is to investigate the relationship between the economic situation and the rate of occupational accidents in Poland. The analysis comprised data for 66 Polish sub-regions taken from the Central Statistical Office's Local Data Bank. The regression analysis with panel data for period 2002-2014 was applied to identify the relationships involved. Four measures of accidents were used: the rates of total occupational accidents, accidents among men and women separately as well as days of incapacity to work due to accidents at work per employee. Four alternative measures assessed the economic situation: gross domestic product (GDP) per capita, average remuneration, the unemployment rate and number of dwelling permits. The confounding variables included were: employment in hazardous conditions and the size of enterprises. The results of the regression estimates show that the number of occupational accidents in Poland exhibits procyclical behavior, which means that more accidents are observed during the times of economic expansion. Stronger relationships were observed in the equations explaining men's accident rates as well as total rates. A weaker and not always statistically significant impact of economic situation was identified for women's accident rates and days of incapacity to work. The results have important implications for occupational health and safety actions. In the periods of higher work intensity employers should focus on appropriate training and supervision of inexperienced workers as well as on ensuring enough time for already experienced employees to recuperate. In terms of public health actions, policy makers should focus on scrutinizing working conditions, educating employers and counteracting possible discrimination of injured employees. Int J Occup Med

    Situation awareness has been defined as the perception of the elements in the environment within volumes of time and space, the comprehension of their meaning, and the projection of their status in the near future. Intensivists often make time-sensitive critical decisions, and loss of situation awareness can lead to errors. It has been shown that simulation-based training is superior to lecture-based training for some critical scenarios. Because the methods of training to improve situation awareness have not been well studied in the medical field, we compared the impact of simulation vs. lecture training using the Situation Awareness Global Assessment Technique (SAGAT) score. To identify an effective method for teaching situation awareness. We randomly assigned 17 critical care fellows to simulation vs. lecture training. Training consisted of eight cases on airway management, including topics such as elevated intracranial pressure, difficult airway, arrhythmia, and shock. During the testing scenario, at random times between 4 and 6 minutes into the simulation, the scenario was frozen, and the screens were blanked. Respondents then completed the 28 questions on the SAGAT scale. Sample items were categorized as Perception, Projection, and Comprehension of the situation. Results were analyzed using SPSS Version 21. Eight fellows from the simulation group and nine from the lecture group underwent simulation testing. Sixty-four SAGAT scores were recorded for the simulation group and 48 scores were recorded for the lecture group. The mean simulation vs. lecture group SAGAT score was 64.3 ± 10.1 (SD) vs. 59.7 ± 10.8 (SD) (P = 0.02). There was also a difference in the median Perception ability between the simulation vs. lecture groups (61.1 vs. 55.5, P = 0.01). There was no difference in the median Projection and Comprehension scores between the two groups (50.0 vs. 50.0, P = 0.92, and 83.3 vs. 83.3, P = 0.27). We found a significant, albeit

    A generic model for the primary cooling system contamination in pressurized water reactors and the resulting radiological consequences has been developed. The functional capability was demonstrated by means of three examples concerning manipulation procedures during revision outages. Activities at the main reactor coolant pumps were studied and the influence of the coolant contamination on the resulting dose rates and collective doses were calculated. The effect of a Co-90 hot spot in a more remote area on the radiation exposure during the specific action at the reactor pumps was considered.

  19. Registered Nurses' Perceptions about the Situation of Family Caregivers to Patients with Heart Failure - A Focus Group Interview Study.

    Full Text Available Heart failure is a growing public health problem associated with poor quality of life and significant morbidity and mortality. The majority of heart failure care is provided by family caregivers, and is associated with caregiver burden and reduced quality of life. Research emphasizes that future nursing interventions should recognize the importance of involving family caregivers to achieve optimal outcomes.The aims of this study are to explore registered nurses' perceptions about the situation of family caregivers to patients with heart failure, and registered nurses' interventions, in order to improve family caregivers' situation.The study has a qualitative design with an inductive approach. Six focus group interviews were held with 23 registered nurses in three hospitals and three primary health care centres. Data were analysed using qualitative content analysis.Two content areas were identified by the a priori study aims. Four categories and nine sub-categories emerged in the analysis process. The content area "Family caregivers' situation" includes two categories: "To be unburdened" and "To comprehend the heart failure condition and its consequences". The content area "Interventions to improve family caregivers' situation" includes two categories: "Individualized support and information" and "Bridging contact".Registered nurses perceive family caregivers' situation as burdensome, characterized by worry and uncertainty. In the PHCCs, the continuity and security of an RN as a permanent health care contact was considered an important and sustainable intervention to better care for family caregivers' worry and uncertainty. In the nurse-led heart failure clinics in hospitals, registered nurses can provide family caregivers with the opportunity of involvement in their relative's health care and address congruence and relationship quality within the family through the use of "Shared care" and or Family-centred care. Registered nurses consider it

    Purpose: The aim of the present study was to determine the acute effects of the `Ecstasy` analogue MDE (3,4-methylendioxyethamphetamine) on the cerebral glucose metabolism (rMRGlu) of healthy volunteers. Method: In a randomised double-blind trial, 16 healthy volunteers without a history of drug abuse were examined with 18-FDG PET 110-120 minutes after oral administration of 2 mg/kg MDE (n=8) or placebo (n=8). Beginning two minutes prior to radiotracer injection, a constant cognitive stimulation was maintained for 32 minutes using a word repetition paradigm in order to ensure constant and comparable mental conditions during cerebral 18-FDG uptake. Individual brain anatomy was represented using T1-weighted 3D flash MRI, followed by manual regionalisation into 108 regions-of-interest and PET/MRI overlay. Absolute quantification of rMRGlu and comparison of glucose metabolism under MDE versus placebo were performed using Mann-Whitney U-test. Results: Absolute global MRGlu was not significantly changed under MDE versus placebo (MDE: 41,8{+-}11,1 {mu}mol/min/100 g, placebo: 50,1{+-}18,1 {mu}mol/min/100 g, p=0,298). The normalised regional metabolic data showed a significantly decreased rMRGlu in the bilateral frontal cortex: Left frontal posterior (-7.1%, p<0.05) and right prefrontal superior (-4.6%, p<0.05). On the other hand, rMRGlu was significantly increased in the bilateral cerebellum (right: +10.1%, p<0.05; left: +7.6%, p<0.05) and in the right putamen (+6.2%, p<0.05). Conclusions: The present study revealed acute neurometabolic changes under the `Ecstasy` analogon MDE indicating a fronto-striato-cerebellar dysbalance with parallels to other psychotropic substances and various endogenous psychoses respectively.

    The aim of this study was to explore the lived experiences of conscious patients in neurosurgical intensive care. Data collection was performed by qualitative interviews using an interview guide. Eleven former patients, seven women and four men, were interviewed two to 14 months after discharge. The interviews were recorded and transcribed verbatim and analysed using an interpretive phenomenological approach. The analysis revealed three themes: To feel safe in an unfamiliar situation, to experience strains and limitations, and to be confirmed as a human being. These three themes culminated in the essence: To feel strong in an unfamiliar situation. Patients experienced a soothing environment where, despite strains, they felt safe being cared for in a ward with specialised medical treatment. When mental and physical strains decreased during the period of care, they experienced the ability to cope with the simplest tasks as a sign of regained identity. Patients' main experience during intensive care was security. Security along with human contact and interaction with staff and next of kin made the patients feel strengthened as human beings in an unfamiliar situation. The fact that the patients were conscious enabled them to understand their situation and to experience security. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Iran’s Kurdistan in general and Ardalan’s Kurdistan in Qajar era in particular was of paramount importance due to its geographic situation as it was located on Iran’s western borders with Ottoman Empire and Baban states. When Qajar government came to power in Iran, Kurdistan region and its environs, was under the leadership of a local dynasty called Ardalan. From the second half of the seventh century of Hijra to the thirteenth century of Hijra, this dynasty in points of its political life dominated parts of Hamadan, Kermanshah as well as some regions of Lorestan besides reigning Kurdistan. Swearing their allegiance to the central government during the reign of First Shah Abbas, Ardalan warriors turned to a covering power between two Iranian and Ottoman empires and offered various services to Iran from Safavid era to Qajar era. Ottomans who had succeeded to prevail over almost three-fourth of Kurdish regions during their quarrels with Safavids were always interested in owning Kurdistan region. Thus, they decided to found the Baban state in Shahrzur region (now is known as Sulaymaniyah in the eleventh century of Hijra in order to expand its influence in this region and reaches a power equilibrium against Ardalan Dynasty in Iran. From this time on, these two local powers were serious political rivals and each one was in some way following the orders issued by their respective central government.

    Full Text Available The neural correlates of rejection in bargaining situations when proposing a fair or unfair offer are not yet well understood. We measured neural responses to rejection and acceptance of monetary offers with event-related potentials (ERPs in mid-adolescents (14-17 years and early adults (19-24 years. Participants played multiple rounds of the Ultimatum Game as proposers, dividing coins between themselves and a second player (responder by making a choice between an unfair distribution (7 coins for proposer and 3 for responder; 7/3 and one of two alternatives: a fair distribution (5/5 or a hyperfair distribution (3/7. Participants mostly made fair offers (5/5 when the alternative was unfair (7/3, but made mostly unfair offers (7/3 when the alternative was hyperfair (3/7. When participants' fair offers (5/5; alternative was 7/3 were rejected this was associated with a larger Medial Frontal Negativity (MFN compared to acceptance of fair offers and rejection of unfair offers (7/3; alternative was 3/7. Also, the MFN was smaller after acceptance of unfair offers (7/3 compared to rejection. These neural responses did not differ between adults and mid-adolescents, suggesting that the MFN reacts as a neural alarm system to social prediction errors which is already prevalent during adolescence.

    Full Text Available The essence of this article is to show the differences and the degree of difficulty in standard and crisis communication. Communication that we use every day in cooperation with the media should serve as the basis and contribution to obtaining certain efficiency of information distribution, which will pay off in a crisis situation. Rescuing a dog named Baltic could prove to be a major crisis in the history of the NMFRI. There were many threats and decisions that could be regarded as unfavourable for the Institute — is it allowed and for the sake of what — to threaten health and life of people to save an animal; what would happen if the rescue action failed? Three mandatory rules for communicating with the media were adopted: Speed — proactive communication 24/24. Transparency —in the full sense of the word. Communicating through the same channels as journalists communicated with the Institute. Strict adherence to these rules resulted in a fact that, in spite of these difficulties, the communication was actually exemplary.

    Full Text Available Multilingual situations are reflected in the lexicon; by consequence, lexical borrowings are powerful evidence for language contact in the prehistory of linguistic communities. This article presents an empirical study on the lexical knowledge of Caucasian Urum speakers, i. e., ethnic Greek speakers in the Small Caucasus, who are bilingual in a variety of Turkish (Urum and Russian. The analysis is based on the established assumption that certain concepts are cross-linguistically associated with a certain likelihood of borrowing. Based on this assumption the data from lexical knowledge allow for insights with respect to the substrate/superstrate status of the involved languages in a multilingual situation and provide evidence for the type of relation (genetic or contact-induced between compared languages.

    2016-07-01

    We validated the usability of a new infusion pump interface designed with a situated Cognitive Engineering approach by comparing it to a reference interface using a novel testing method employing repeated measurements and process measures, in addition to traditional outcome measures. The sample consisted of 25 nurses who performed eight critical tasks three times. Performance measures consisted of number and type of errors, deviations from a pre-established normative path solution, task completion times, number of keystrokes, mental effort and preferences in use. Results showed that interaction with the new interface resulted in 18% fewer errors, 90% fewer normative path deviations, 42% lower task completion times, 40% fewer keystrokes, 39% lower mental effort and 76% more subjective preferences in use. These outcomes suggest that within the scope of this case study, combining the situated Cognitive Engineering approach with a novel testing method addresses various shortcomings of earlier testing methods.

    To explore the effect that different activities included in first aid training can have on an individual's propensity to act in a medical emergency. Additional pilot-developed activities were added to a core first aid training session to create six unique groups, including a control group where no activities were added. Participants rated their agreement to pre-identified fears following the course and scored their self-efficacy and willingness to act before, immediately after and 2 months after the course. Change values were compared between groups. Three locations in the UK (community halls, schools). 554 members of the public were recruited using advertising and community groups. A deliberately broad demographic was sought and achieved using targeted approaches where a particular demographic was deficient. Each participant attended one British Red Cross first aid course lasting 2 h. The same questionnaire was completed by all participants before and after each course. Two months later all participants were asked a series of follow-up questions. All courses showed an increase in self-efficacy and willingness to act immediately following the course. The course, which included both factual information relevant to helping in an emergency and 'helper' identity activities, produced significantly more positive responses to pre-identified fears. Activities which allow the learner to explore and discuss behaviour in an emergency situation can effectively increase the learner's propensity to act. First aid education should be expanded to support the learner to develop both the skill and the will to help. Published by the BMJ Publishing Group Limited.

    Exclusive breastfeeding until six months followed by the introduction of solids and continued breastfeeding is recommended by the World Health Organisation. The dominant approach to achieving this has been to educate and support women to start and continue breastfeeding rather than understanding behaviour change processes from a broader perspective. Serial qualitative interviews examined the influences of significant others on women's feeding behaviour. Thirty-six women and 37 nominated significant others participated in 220 interviews, conducted approximately four weekly from late pregnancy to six months after birth. Responses to summative structured questions at the end of each interview asking about significant influences on feeding decisions were compared and contrasted with formative semi-structured data within and between cases. Analysis focused on pivotal points where behaviour changed from exclusive breastfeeding to introducing formula, stopping breastfeeding or introducing solids. This enabled us to identify processes that decelerate or accelerate behaviour change and understand resolution processes afterwards. The dominant goal motivating behaviour change was family wellbeing, rather than exclusive breastfeeding. Rather than one type of significant other emerging as the key influence, there was a complex interplay between the self-baby dyad, significant others, situations and personal or vicarious feeding history. Following behaviour change women turned to those most likely to confirm or resolve their decisions and maintain their confidence as mothers. Applying ecological models of behaviour would enable health service organisation, practice, policy and research to focus on enhancing family efficacy and wellbeing, improving family-centred communication and increasing opportunities for health professionals to be a constructive influence around pivotal points when feeding behaviour changes. A paradigm shift is recommended away from the dominant approach of

    The co-combustion of wastes in power stations is an additional option for the thermal treatment of certain waste materials and thus for complying with the specifications of the German TA-Siedlungsabfall (technical directive on disposal of municipal solid waste). The present investigation compiles the status of knowledge about co-combustion of sewage sludge, biomass and selected waste materials in coal-fired power stations. The results are meant to provide extensive assistance to evaluate the processes and thus to contribute to sort out uncertainties, both on the part of power plant operators and of the authorities. Based on the information acquired, the report shall point out the gaps in knowledge, the further need for research and development and the need for action conerning the authorities. By enquiries at disposal enterprises, power station operators as well as authorities, the literature work was completed and a comprehensive view of the current situation in Germany elaborated. The report points out the legal conditions of co-combustion and supplementary fuel potentials, presents the process engineering of co-combustion, and examines the obstacles encountered during the technical conversion, the environmental questions, and the potential for co-combustion of the above materials in existing power stations. The electrical power sector is subject to strong changes due to the liberalisation of the energy market. The pressure on costs has increased and the periods available for planning are shorter. On the one hand, this arouses an increased interest in co-combustion of waste materials because of possible additional payments for the wastes. On the other hand, however, initiatives in this respect are counteracted by high investments costs necessary for the introduction of co-combustion with the existing high environmental standards. What is more, the competitive situation reduces the exchange of experience between the power station operators. Co-combustion of sewage

    The aim of this paper is to ascertain if the subjective perception of the economic situation of a household is associated with the prevalence of disability in old age, net of education level. Subjective economic perception is less non-response biased. Knowing if the self-perceived economic situation is related to disability over and above education level has important implications both for understanding the mechanisms that lead to disability and for selecting policies to reduce it. This is a transversal study based on the pilot of the ELES survey, which is a representative survey of non-institutionalised Spaniards aged 50 and over. Only individuals whose job income levels were fixed before becoming disabled were selected to avoid the main source of reverse causality. Disability was defined as having difficulty in carrying out any of 12 activities of daily living. Education level, difficulty in making ends meet, self-perceived relative economic position of the household, age, gender, psychological disposition, and alcohol and tobacco consumption were introduced as independent variables in binary logistic models. The working sample is made up of 704 individuals of aged 60 and over. The subjective household economic situation, measured in two different ways, is strongly and consistently related with the prevalence of disability net of age, gender, education level and psychological disposition. After adjusting for age and gender, education level is no longer associated with disability. However, having economic difficulties has the same effect on disability prevalence as being 10 years older, or being a woman instead of a man. As the economic situation of the elderly is much easier to improve than their formal education, our findings support feasible interventions which could lead to a reduction in the prevalence of disability.

    This study provides empirical data about shipboard practices in bridge operations on board a selection of platform supply vessels (PSVs). Using the theoretical concept of distributed situation awareness, the study examines how situation awareness (SA)-related information is distributed and coordinated at the bridge. This study thus favours a systems approach to studying SA, viewing it not as a phenomenon that solely happens in each individual's mind but rather as something that happens between individuals and the tools that they use in a collaborative system. Thus, this study adds to our understanding of SA as a distributed phenomenon. Data were collected in four field studies that lasted between 8 and 14 days on PSVs that operate on the Norwegian continental shelf and UK continental shelf. The study revealed pronounced variations in shipboard practices regarding how the bridge team attended to operational planning, communication procedures, and distracting/interrupting factors during operations. These findings shed new light on how SA might decrease in bridge teams during platform supply operations. The findings from this study emphasize the need to assess and establish shipboard practices that support the bridge teams' SA needs in day-to-day operations. Provides insights into how shipboard practices that are relevant to planning, communication and the occurrence of distracting/interrupting factors are realized in bridge operations.Notes possible areas for improvement to enhance distributed SA in bridge operations.

    Few psychological studies, if any, can claim a legacy as imposing as the obedience studies of Stanley Milgram. Their impact was of notable consequence in the separate spheres of research ethics, research design, and theory in psychology, and they changed the ways that psychologists conceptualize and conduct their research. The authors discuss the legacy of these studies, especially as they effected dramatic changes in the fields of personality and social psychology. The article concludes with a discussion of what psychological science has lost in the aftermath of Milgram--high impact studies--and the salience that such research has in illuminating the most significant problems of our society, studies that could produce great human benefits.

Vor allem Kinder aus bildungsfernen Milieus und mit Migrationshintergrund sind hiervon betroffen (vgl. Becker/Lauterbach 2004; Diefenbach 2007; Rabe-Kleberg 2010. An dieser Einsicht knüpft das Forschungs- und Interventionsprojekt KidSmart – Medienkompetent zum Schulübergang an. Medienpädagogische Arbeit steht hier im Kontext der Vorbereitung auf den Schulübergang. Durch kreative Medienarbeit soll ein Gegengewicht zur eher passiven Mediennutzung geschaffen werden. Ziel ist es Bildungsunterschiede von Kindern bereits vor Schulbeginn auszugleichen.Already before starting school educational disadvantages in the part of reading and media socialization can be identified within Germany. Generally affected are children of less educated families and children with migration background (Becker/Lauterbach 2004; Diefenbach 2007; Rabe-Kleberg 2010. Therefore, an exceptional intervention and research project KidSmart – media competence by entering school was initiated in the area of early childhood education. Within this project media-pedagogical work is corresponding with preparation of entering school. The intention is to create a counterbalance to passive media use by creative media work. The scope of the project is to fight against early educational disadvantages.

    Team situational awareness (TSA) is critical for effective teamwork and supports dynamic decision making in unpredictable, time-pressured situations. Simulation provides a platform for developing and assessing TSA, but these efforts are limited by suboptimal measurement approaches. The objective of this study was to develop and evaluate a novel approach to TSA measurement in interprofessional emergency medicine (EM) teams. We performed a multicenter, prospective, simulation-based observational study to evaluate an approach to TSA measurement. Interprofessional emergency medical teams, consisting of EM resident physicians, nurses, and medical students, were recruited from the University of Washington (Seattle, WA) and Wayne State University (Detroit, MI). Each team completed a simulated emergency resuscitation scenario. Immediately following the simulation, team members completed a TSA measure, a team perception of shared understanding measure, and a team leader effectiveness measure. Subject matter expert reviews and pilot testing of the TSA measure provided evidence of content and response process validity. Simulations were recorded and independently coded for team performance using a previously validated measure. The relationships between the TSA measure and other variables (team clinical performance, team perception of shared understanding, team leader effectiveness, and team experience) were explored. The TSA agreement metric was indexed by averaging the pairwise agreement for each dyad on a team and then averaging across dyads to yield agreement at the team level. For the team perception of shared understanding and team leadership effectiveness measures, individual team member scores were aggregated within a team to create a single team score. We computed descriptive statistics for all outcomes. We calculated Pearson's product-moment correlations to determine bivariate correlations between outcome variables with two-tailed significance testing (p situational

    Due to the high rates of antimicrobial resistance to certain antibiotics, together with the emergence of Neisseria gonorrhoeae (NG) with reduced susceptibility and resistance to third-generation cephalosporins, gonococcal infection is becoming a public health problem. The objectives of the study were: To keep track of the antimicrobial susceptibility of NG strains obtained from January to August 2011. To study the population dynamics. The antimicrobial susceptibility was studied by disk-diffusion and E-test. The genotyping was performed by NG-MAST method. Of a total of 100strains studied, 59% showed intermediate sensitivity to penicillin and 9% were resistant. According to EUCAST, we detected 3gonococci with reduced susceptibility to ceftriaxone, 10 to cefixime and one with high-level resistance to both antibiotics (MIC 1.5μg/ml). MIC50 and MIC90 to cefixime were 0.016 and 0.125μg/ml, respectively, whereas to ceftriaxone they were <0.016 and 0.064μg/ml, respectively. Almost all (99%) of the strains were resistant to doxycycline, 53% to ciprofloxacin, 3% to azithromycin, and 1% to spectinomycin. The most prevalent ST was ST1407, predominantly associated to resistance or reduced sensitivity to cephalosporins or macrolides. NG has developed significant rates of resistance to various antibiotics. One strain has been detected with high level resistance to third generation cephalosporins, and several strains with reduced susceptibility. An increase in MIC50 and MIC90 to these antibiotics has also been observed. NG population structure remains stable and common to the rest of Europe, although two new ST (ST7226 and ST7227) have been identified that could be selected and acquire high levels of resistance to cephalosporins.

    Full Text Available Pedestrian’s crashes account for approximately 7% of road death in Malaysia. Even though the percentage is smaller compared to motorcycle-related crashes, amount of road crashes involving pedestrians in Malaysia is a serious concern. The objective of this study is to establish the common type of distraction for Malaysian. Crashes among pedestrians usually highly recorded at straight road followed by inter-section road type. For that, study focusing on the type of distraction among pedestrians while crossing the road by using video recording method. Two type of road were selected observational field survey – signalized and non-signalized intersection. A video recording method was used to analyse the behaviour of pedestrians crossing with or without distraction. Approximately 375 samples were observed while crossing with various type of distraction such as eating, texting, mobile phone talking and others. The study found the highest distraction type observed among pedestrians is usage of electronic equipment-mobile phone with 84.8% followed by other type of distraction – smoking and talking with more that 5%. Mobile phone distraction cause a significant effect in term of time to cross which average time to cross was 14.77 second. The overall results provide a prevalence information that is useful in the development of countermeasures aimed at improving pedestrians’ safety.

  3. [Studying Marxist theory on population and initiating a new situation in demographic research].

    Science.gov (United States)

    Tain, Z

    1983-03-29

    Within Marxist ideology are important population theories that led to the establishment of demography and the work of population control in China. Marxist population theory should be studied in order to build a scientific system of concepts in population theory. Both Marx and Engels spoke of the relationship between human reproduction and material production, and of how the modes of social development determine population development. Marx also established the view that a normal population and surplus population both were mutually adaptable with a certain production basis. In any historical period, the total population is not determined subjectively by man's wishes, but is a product of historical development. The Maoist population theory is derived from Marxist theory. Borrowing from historical materialism, Mao said that of all the objects in the world, man is the most precious. Nevertheless, he continued, while China's large population is good, it brings many difficulties; thus, population must be controlled. The study of demography should follow Marxist and Maoist population theories, even though the study of Marixst population theory is relatively recent and much remains to be learned.

    Full Text Available Sickle cell disease is a serious genetic disorder affecting 1/235 births in French Guiana. This study aimed to describe the follow-up of pregnancies among sickle cell disease patients in Cayenne Hospital, in order to highlight the most reported complications. 62 records of pregnancies were analyzed among 44 females with sickle cell disease, between 2007 and 2013. Our results were compared to those of studies conducted in Brazil and Guadeloupe. There were 61 monofetal pregnancies and 2 twin pregnancies, 27 pregnancies among women with SS phenotype, 30 SC pregnancies, and five S-beta pregnancies. The study showed that the follow-up of patients was variable, but no maternal death was found. We also noted that the main maternofetal complications of pregnancies were anemia (36.5%, infection (31.7%, vasoocclusive crisis (20.6%, preeclampsia (17.5%, premature birth (11.1%, intrauterine growth retardation (15.9%, abnormal fetal heart rate (14.3%, and intrauterine fetal death (4.8%. Pregnancies were more at risk among women with SS phenotype. Pregnancy in sickle cell disease patients requires a supported multidisciplinary team including the primary care physician, the obstetrician, and the Integrated Center for Sickle Cell Disease.

    This paper is a report of a qualitative study of mobilization of knowledge within the critical thinking process deployed by female undergraduate nursing students in practical care situations. Holistic practice is based on variety of knowledge mobilized by a critical thinking process. Novices and, more specifically, students experience many difficulties in this regard. Therefore, a better understanding of the knowledge they mobilize in their practice is important for nurse educators. A qualitative study, guided by grounded theory, was carried out. Sixteen nursing students, registered in an undergraduate programme in an Eastern Canadian university, were recruited. Descriptions of practical care situations were obtained through explicitation interviews in 2007. A sociodemographic questionnaire, semi-structured interviews and field notes were also used. Data were analysed using an approach based on grounded theory. An additional stage of analysis involved data condensation. Various types of knowledge guide nursing students' practice. These include intrapersonal, interpersonal, perceptual, moral/ethical, experiential, practical, scientific and contextual knowledge. The mobilization of these types of knowledge is only possible when the process of critical thinking has attained a higher level, giving rise to a new knowledge that we have termed combinational constructive knowledge rather than aesthetic knowledge. Clarification of the types of knowledge guiding the practice of student nurses and of the role of critical thinking in their mobilization could lead to innovative educational strategies. The findings provide guidance for the revision and development of both academic and clinical training programmes. © 2011 Blackwell Publishing Ltd.

  6. Publicly Available Geosynchronous (GEO) Space Object Catalog for Future Space Situational Awareness (SSA) Studies

    Science.gov (United States)

    Koblick, D. C.; Shankar, P.; Xu, S.

    Previously, there have been many commercial proposals and extensive academic studies regarding ground and space based sensors to assist a space surveillance network in obtaining metric observations of satellites and debris near Geosynchronous Earth Orbit (GEO). Most use physics based models for geometric constraints, lighting, and tasker/scheduler operations of sensor architectures. Under similar physics modeling assumptions, the space object catalog is often different due to proprietary standards and datasets. Lack of catalog commonality between studies creates barriers and difficulty comparing performance benefits of sensor trades. To solve this problem, we have constructed a future GEO space catalog from publicly available datasets and literature. The annual number of new payloads and rocket bodies is drawn from a Poisson distribution while the growth of the current GEO catalog is bootstrapped from the historical payload, upper stage, and debris data. We adopt a spherically symmetric explosion model and couple it with the NASA standard breakup model to simulate explosions of payloads and rocket bodies as they are the primary drivers of the debris population growth. The cumulative number of fragments follow a power-law distribution. Result from 1,000 random catalog growth simulations indicates that the GEO space object population in the year 2050 will include over 3,600 objects, nearly half of which are debris greater than 10 cm spherical diameter. The number of rocket bodies and dead payloads is projected to nearly double over the next 33 years. For comparison, the current Air Force Space Command catalog snapshot contains fewer than 50 pieces of debris and coarse Radar Cross Section (RCS) estimates which include: small, medium, and large. The current catalog may be sufficient for conjunction studies, but not for analyzing future sensor system performance. The 2050 GEO projected catalog will be available online for commercial/academic research and development.

    The Szemlőhegy-cave is one of the well-known hydrothermal caves of the Rózsadomb area of Budapest, which have been used for speleotherapy of respiratory diseases for years. It is known from the periodically changing airborne radon activity concentration data, that airflow of seasonally reversed direction are formed along the cave passages and fissures due to the temperature difference between the surface and cave air. This means that an intensive interaction takes place between the cave and its environment. The pollution of nearby waters and the urban atmospheric air represents a real danger for these caves below Buda, which recently became the part of the UNESCO World Heritage. The study of cave aerosols should be very important from the point of view of either the control possibilities of the environmental impact or speleotherapy, and probably helps in getting acquainted with the cave-forming processes. In this work we applied our standard aerosol sampling method to the high-humidity environment of the caves, and we studied the elemental composition, size fractionation as well as the spatial distribution and the seasonal variation of cave aerosols. Thanks to the sensitivity of PIXE traces of anthropogenic pollution of the Budapest air are shown in the Szemlőhegy-cave. Measured elemental concentrations remained less than one-tenth the air quality standard valid for the increasingly protected areas.

    Drug shortages were a complex global problem. The aim of this study was to analyze, characterize, and assess the drug shortages, and identify possible solutions in Shaanxi Province, western China. A qualitative methodological approach was conducted during May-June 2015 and December 2015-January 2016. Semi-structured interviews were performed to gather information from representatives of hospital pharmacists, wholesalers, pharmaceutical producers, and local health authorities. Thirty participants took part in the study. Eight traditional Chinese medicines and 87 types of biologicals and chemicals were reported to be in short supply. Most were essential medicines. Five main determinants of drug shortages were detected: too low prices, too low market demands, Good Manufacturing Practice (GMP) issues, materials issues, and approval issues for imported drugs. Five different solutions were proposed by the participants: 1) let the market decide the drug price; 2) establish an information platform; 3) establish a reserve system; 4) enhance the communication among the three parties in the supply chain; and 5) improve hospital inventory management. Western China was currently experiencing a serious drug shortage. Numerous reasons for the shortage were identified. Most drug shortages in China were currently because of "too low prices." To solve this problem, all of the stakeholders, especially the government, needed to participate in managing the drug shortages.

Five different solutions were proposed by the participants: 1 let the market decide the drug price; 2 establish an information platform; 3 establish a reserve system; 4 enhance the communication among the three parties in the supply chain; and 5 improve hospital inventory management.Western China was currently experiencing a serious drug shortage. Numerous reasons for the shortage were identified. Most drug shortages in China were currently because of "too low prices." To solve this problem, all of the stakeholders, especially the government, needed to participate in managing the drug shortages.

    To determinate the prevalence of patients with Home Enteral Nutrition (HEN) in Galicia. Transversal study. Patients aged > or = 14 years, treated with HEN in our community since January 1998 to December 1999. Population of reference was 1.789.983. Questionnaire previously designed. During the study period were treated 2,784 patients which represent a prevalence of 10.34 cases/10,000 inhabitants, being 18.8 for La Coruña, 1.3 for Lugo, 0.4 for Ourense and of the 20.85 for Pontevedra. The mean age of the patients was of 56 +/- 2.29 years (range 14-96). The Clinics units that required more frequently HEN were the Medical Units (48.3%), followed of the Surgery Units (20.2%) and the Primary Care Units (19.2%). Neurological abnormalities (43.6%), Neoplasias (30.7%) and Intestinal Inflammatory Disease (10.5%) were patients more frequently required HEN. Regarding to administration route 58.3%, 28.46%, 9.87%, 0.5% and 0.65% used oral, nasogastric tube, PEG, gastrostomy and yeyunostomy respectively. The Index of complications was 0.18 of patient-year, due to gastrointestinal anomalies 0.12 patient-year, mechanical 0.09 patient-year. The index of hospitalizations in relation to the nutritional treatment was 0.026 patient-year. The prevalence of HEN in our community is of 10.34 cases/10,000 inhabitants. This kind of treatment is more frequently in the areas with high-density population. The frequency of complications was low. This data may be useful to compare with date from other areas and countries.

    Full Text Available Tarek BADAWIA describes in his thesis how immigrant young people with a high level of educational achievement develop a new strategy of handling two different cultures. By using focused interviews BADAWIA generates the theory of the "third chair". The author paints a picture showing how the young immigrants interviewed create a new cross-cultural identity out of both of their cultures. By doing this they are no longer "sitting between two chairs." With this theory BADAWIA follows recent developments within intercultural educational research. What is new in this study is that BADAWIA asks the young immigrant people themselves and that he focuses in particular on their way of creating and handling their life. Unfortunately, BADAWIA uses a very complicated and artificial language. Nevertheless, the study is worth reading because it opens an authentic view of the environment of juvenile immigrants.

    The effect of a chemical application on the epigeic fauna, especially parasitic Hymenoptera, of an oak-hornbeam-forest was studied by means of ground photoelectors. In a large area project two out of three study plots of 1 ha size each received a single treatment with cypermethrin resp. propoxur. In other experiments with small ground photoelectors only small areas were treated with several chemicals. The following parameters, on the basis of animal groups (orders, families) or species, are suitable bioindicators for chemical stress in ecosystems: 1. alternations in numbers of caught animals, 2. alterations in dominance identity between experimental and control plot and between different years on the same plot, 3. alterations in height and direction of fluctuations, especially variance of the fluctuation coefficients. To a lesser degree, also changes in trophic structure can be used. (orig./MG).

    An exponential increase of PBDE levels in breast milk from Sweden between 1972 and 1997 has been reported, which is in contrast to the continuous decline of other chlorinated POPs in breast milk. Also in blood samples from Germany, an increasing trend has been observed during the period from 1985 to 1999. The knowledge about human exposure pathways, which contribute to the PBDE body burden, is very limited. Consumption of food of animal origin, inhalation or ingestion of dust and further factors possibly influencing the PBDE levels in human matrices, like age, breast-feeding or smoking are under discussion. Only a few data on PBDE levels in breast milk from Germany have been published. To fill the data gaps, a controlled study was started in 2001 to characterise the PBDE levels in human milk from Germany with special efforts to identify and quantify deca-BDE-209. Furthermore, it was intended to verify potential factors possibly influencing PBDE levels. Two main hypotheses were proposed: (1) Are PBDE levels in breast milk from mothers consuming traditional food (omnivores) higher than those found in breast milk from mothers consuming vegetarian or vegan food? and (2) Are the PBDE levels found in human milk after a three-months period of breast-feeding lower than those detected at the beginning or does breast feeding result in a lower body burden, respectively? This paper summarises preliminary results. Further analytical data and results of data evaluation will be presented at the conference.

    Paranoia may build directly upon negative thoughts about the self. There have been few direct experimental tests of this hypothesis. The aim of the study was to test the immediate effects of manipulating self-esteem in individuals vulnerable to paranoia. A two condition cross-over experimental test was conducted. The participants were 26 males reporting paranoid ideation in the past month. Each participant experienced a neutral immersive virtual reality (VR) social environment twice. Before VR participants received a low self-confidence manipulation or a high self-confidence manipulation. The order of manipulation type was randomized. Paranoia about the VR avatars was assessed. The low self-confidence manipulation, relative to the high self-confidence manipulation, led to significantly more negative social comparison in virtual reality and higher levels of paranoia. Level of self-confidence affects the occurrence of paranoia in vulnerable individuals. The clinical implication is that interventions designed to improve self-confidence may reduce persecutory ideation.

    The primary care reform (PCR) has give rise to some major changes in the nursing profession. The objectives of this study are to analyze the achievements made by the nurses, to identify the problems they currently have in primary care and to suggest some lines along which work can be done for the future. Qualitative research (focal group method). Eight groups were made segmented by occupational category and the position held. Scope of the analysis: the role of nurses, services supply and organization, participation and management, marketing and training. In the opinion of those surveyed, the PCR has entailed a broadening of the nurses' skills, although their role is still well-defined. The nurses are of the opinion that there is no listing of services inherent to nursing despite the leading role they obviously play in home care and health education. The need has been identified of assess the existing health programs in terms of results. Concerning to health services organization, main problems were related to the lack of adapting staffing in keeping with the rise in population and difficulties of internal communications within the health professional teams and the very small degree to which nursing services are disseminated. The need is felt of broadening pre-diploma training with regard to some subjects (health education) and skills (teamwork). Although the PCR has meant improvements for the nurses, solutions have as yet to have been provided to some aspects (including defining a listing of services, adapting staffing, internal communications, marketing, training) and given the opportunity the transferring of authorities over health care entail, further progress must be made toward innovative proposals to improve the health services.

    IceCube is an 1 km{sup 3} large observatory at the south pole. It consists of the surface detector IceTop and the underground detector In-Ice. By the detection of Cherenkov Radiation iceCube tries to determine the sources of cosmic radiation and cosmic neutrinos. IceTop possesses a large number of IceTop tanks (ITT), which are filled with ice. In these tanks the Cherenkov radiation of the cosmic radiation can be detected with so-called digital optical modules. By this it is possible to determine the chemical composition of the cosmic radiation. Simultaneously this surface detector serves also as veto for the In-Ice detector. In this bachelor thesis the charge spectra in the ITT at DESY were studied under regardment of the electromagnetic, hadronic, and muonic component. Additionally in cooperation with 6 1 m{sup 2} large scintillator planes by different coincidence conditions a direction selection of the cosmic radiation could be performed. By this the positions of the muon peaks could be considered for different conditions.

    This book presents teaching concepts for the self-reliant acquisition of knowledge and skills around the topic of photovoltaics at learning stations and in teacher-centered classroom work. These concepts have been developed by the author and proven in practical school teaching and pedagogic training. The book thus makes a contribution to contemporary competence research. Its most important results are as follows: It is shown that the choice of photovoltaics as a subject matter is justifiable from a societal viewpoint as well as in respect of pedagogic theory and subject didactics. It is shown that the particle model can be used to describe the design and functioning of solar cells in physics lessons (elementary explanation of conduction processes in semiconductors). Analyses of pupils' prior experience with photovoltaics show that this is of a phenomenological nature. These empirical studies have shown a large learning increment in pupils both during work at the learning stations and in teacher-centered classroom work. The results show that pupils of forms ten and eleven are capable of acquiring new knowledge and skills in a self-reliant manner. The tasks to be performed at the individual stations were analysed by the author and other experts with respect to their demands on pupils' competence. It transpired that the experts were largely of the same opinion when it came to assigning the tasks involved to the four competence areas. Large differences were seen in the assignment of tasks to the different types of demands.

    The topological analysis of experimentally determined electron density distributions, employing the quantum theory of atoms in molecules developed by Richard FW Bader, was used in this thesis to study chemically or physically motivated questions in appropriate model systems. First, transition metal complexes with activated C-H bonds or Si-H bonds were examined which led to a better understanding of agostic interactions. An important tool during these investigations is the so called atomic graph, which describes the characteristic spatial arrangement of the critical points of the Laplacefield of the electron density distribution in the valence shell of the relevant atoms. It reveals zones with a locally concentrated or depleted electron density distribution. This leads to the empirical rule, that a strong activation of C-H bonds or Si-H bonds is only observed when the hydrogen atom faces a pronounced charge depletion zone at the transition metal atom. In addition, the quasi one-dimensional rare-earth transition metal carbides Sc{sub 3}FeC{sub 4}, Sc{sub 3}CoC{sub 4} and Sc{sub 3}NiC{sub 4} were examined. Although all three compounds are isotypic at room temperature, it was revealed during this thesis, that only Sc{sub 3}CoC{sub 4} undergoes a structural phase transition at a temperature of ∝ 70 K and becomes superconducting below a critical temperature of 4.5 K. The main reason for this behaviour is the variation of the valence electrons through the exchange of Fe by Co or Ni. This results in the occupation of progressively higher energy electronic states and a raising of the Fermi level. The change in the nature of the electronic states at the Fermi level is in turn reflected by the different atomic graphs of the transition metal atoms and the distinct physical properties of these three compounds.

    Background: Despite the fact that adverse health effects are not confirmed for exposure to radiofrequency electromagnetic field (RFEMF) levels below the limit values, as defined in the guidelines of the International Commission on Non-Ionizing Radiation Protection, many persons are worried about possible adverse health effects caused by the RF-EMF emitted from mobile phone base stations, or they attribute their unspecific health complaints like headache or sleep disturbances to these fields. Method: In the framework of a cross-sectional study a questionnaire was sent to 4150 persons living in predominantly urban areas. Participants were asked whether base stations affected their health. Health complaints were measured with standardized health questionnaires for sleep disturbances, headache, health complaints and mental and physical health. 3,526 persons responded (85%) to the questionnaire and 1,808 (51%) agreed to dosimetric measurements in their flats. Exposure was measured in 1,500 flats. Results: The measurements accomplished in the bedrooms in most cases showed very low exposure values, most often below sensitivity limit of the dosimeter. An association of exposure with the occurrence of health complaints was not found, but an association between the attribution of adverse health effects to base stations and the occurrence of health complaints. Conclusions: However, concerns about health and the attribution of adverse health effects to these mobile phone base stations should be taken serious and require a risk communication with concerned persons. Future research should focus on the processes of perception and appraisal of RF-EMF risks, and ascertain the determinants of concerns and attributions in the context of RF-EMF. (orig.)

    The slaughter of pregnant cattle and the fate of the foetuses are relatively new subjects in the field of animal welfare. The Scientific Committee on Veterinary Measures relating to Public Health (SCVPH), however, does not believe this topic to be a critical issue because of the hitherto supposed rare occurrence of this practice. Some previous studies though, contradict this assessment, emphasising its relevance to animal welfare. With regard to the heterogeneous study design of previous investigations, the objective of this study is to evaluate the current situation concerning the slaughter of pregnant cattle in different German abattoirs. Additionally, the prevalence was assessed semi-quantitatively on the basis of a cross-sectional, voluntary and anonymous survey that was conducted amongst senior veterinary students of the University of Leipzig from 2010 until 2013. Of 255 evaluable questionnaires, 157 (63.6%) mention the slaughter of pregnant cattle, corresponding to 76.9% of all visited abattoirs. Slaughter of pregnant cattle is reported often (>10% of females) in 6 (3.8%), frequently (1-10% of females) in 56 (35.7%), and rarely (slaughter of pregnant cattle is a common and widespread practice in German abattoirs. The SCVPH's assumption that pregnant cattle are only slaughtered in rare exceptional cases can no longer be maintained. The high proportion of foetuses in the second and third gestational stage must also be considered. In this context the implementation of suitable studies and detailed analysis of the current situation is indispensable to ensure the high standards in animal welfare in Germany and Europe.

    The implementation of mobile health (mHealth) projects in low- and middle-income countries raises high and well-documented expectations among development agencies, policymakers and researchers. By contrast, the expectations of direct and indirect mHealth users are not often examined. In preparation for a proposed intervention in the Nouna Health District, in rural Burkina Faso, this study investigates the expected benefits, challenges and limitations associated with mHealth, approaching these expectations as a form of situated knowledge, inseparable from local conditions, practices and experiences. The study was conducted within the Nouna Health District. We used a qualitative approach, and conducted individual semi-structured interviews and group interviews (n = 10). Participants included healthcare workers (n = 19), godmothers (n = 24), pregnant women (n = 19), women with children aged 12-24 months (n = 33), and women of childbearing age (n = 92). Thematic and content qualitative analyses were conducted. Participants expect mHealth to help retrieve patients lost to follow-up, improve maternal care monitoring, and build stronger relationships between pregnant women and primary health centres. Expected benefits are not reducible to a technological realisation (sending messages), but rather point towards a wider network of support. mHealth implementation is expected to present considerable challenges, including technological barriers, organisational challenges, gender issues, confidentiality concerns and unplanned aftereffects. mHealth is also expected to come with intrinsic limitations, to be found as obstacles to maternal care access with which pregnant women are confronted and on which mHealth is not expected to have any significant impact. mHealth expectations appear as situated knowledges, inseparable from local health-related experiences, practices and constraints. This problematises universalistic approaches to mHealth knowledge, while nevertheless hinting at

    Irony comprehension requires integration of social contextual information. Previous studies have investigated temporal aspects of irony processing and its neural substrates using psychological/electroencephalogram or functional magnetic resonance imaging methods, but have not clarified the temporospatial neural mechanisms of irony comprehension. Therefore, we used magnetoencephalography to investigate the neural generators of alpha-band (8-13Hz) event-related desynchronization (ERD) occurring from 600 to 900ms following the onset of a critical sentence at which social situational contexts activated ironic representation. We found that the right anterior temporal lobe, which is involved in processing social knowledge and evaluating others' intentions, exhibited stronger alpha ERD following an ironic statement than following a literal statement. We also found that alpha power in the left anterior temporal lobe correlated with the participants' communication abilities. These results elucidate the temporospatial neural mechanisms of language comprehension in social contexts, including non-literal processing. Copyright © 2017 Elsevier Inc. All rights reserved.

    The current study compares the effects of experimentally induced positive anticipatory thinking and distraction in preadolescents aged 12-13. Eighty-seven participants were instructed to either engage in positive anticipatory thoughts or perform a distraction task while preparing to perform a sporting activity in front of their peers. Results revealed that trait social anxiety was associated with more negative estimates of sport performance and catastrophic thoughts relating to the impending sport activity. Additionally, compared to children who distracted, children in the positive anticipation condition showed significantly increased anxiety levels, more catastrophic thoughts and more negative predictions of sport performance and appearance, although these effects did not appear to interact with trait social anxiety. Finally, no significant manipulation effect on participants' observable behavior was found. The findings further highlight the utility of distracting from an impending, anxiety-provoking situation to keep anxious feelings to a low level. © 2017 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    2009-08-01

    Full Text Available Like in many other transition countries, agriculture in Georgia is usually termed as subsistence farming. Lack of employment opportunities and insufficient household income make rural people dependent on state-funded pensionschemes and agricultural production. Similarly, the income-disparity between rural households is also noticed remarkably, while citizens of smaller towns possess, on average, higher income. The study presented in this report is intended to explore the situation of rural households concerning parcel size, employment opportunities, income sources and income disparities between citizens of villages and small towns, by presenting findings obtained during a field survey conducted during the months of March and May 2008 in the Kakheti region in eastern Georgia.

  12. Situational theory of leadership.

    Waller, D J; Smith, S R; Warnock, J T

    1989-11-01

    The situational theory of leadership and the LEAD instruments for determining leadership style are explained, and the application of the situational leadership theory to the process of planning for and implementing organizational change is described. Early studies of leadership style identified two basic leadership styles: the task-oriented autocratic style and the relationship-oriented democratic style. Subsequent research found that most leaders exhibited one of four combinations of task and relationship behaviors. The situational leadership theory holds that the difference between the effectiveness and ineffectiveness of the four leadership styles is the appropriateness of the leader's behavior to the particular situation in which it is used. The task maturity of the individual or group being led must also be accounted for; follower readiness is defined in terms of the capacity to set high but attainable goals, willingness or ability to accept responsibility, and possession of the necessary education or experience for a specific task. A person's leadership style, range, and adaptability can be determined from the LEADSelf and LEADOther questionnaires. By applying the principles of the situational leadership theory and adapting their managerial styles to specific tasks and levels of follower maturity, the authors were successful in implementing 24-hour pharmacokinetic dosing services provided by staff pharmacists with little previous experience in clinical services. The situational leadership model enables a leader to identify a task, set goals, determine the task maturity of the individual or group, select an appropriate leadership style, and modify the style as change occurs. Pharmacy managers can use this model when implementing clinical pharmacy services.

    Full Text Available The article deals with the investigation of theoretical and methodological principles of situational analysis. The necessity of situational analysis is proved in modern conditions. The notion “situational analysis” is determined. We have concluded that situational analysis is a continuous system study which purpose is to identify dangerous situation signs, to evaluate comprehensively such signs influenced by a system of objective and subjective factors, to search for motivated targeted actions used to eliminate adverse effects of the exposure of the system to the situation now and in the future and to develop the managerial actions needed to bring the system back to norm. It is developed a methodological approach to the situational analysis, its goal is substantiated, proved the expediency of diagnostic, evaluative and searching functions in the process of situational analysis. The basic methodological elements of the situational analysis are grounded. The substantiation of the principal methodological elements of system analysis will enable the analyst to develop adaptive methods able to take into account the peculiar features of a unique object which is a situation that has emerged in a complex system, to diagnose such situation and subject it to system and in-depth analysis, to identify risks opportunities, to make timely management decisions as required by a particular period.

    Full Text Available Named as 4+4+4 by the public, the law which extends the compulsory education in Turkey to 12 years stage by stage and which demands some amendments in Elementary Education Law Number 6287 and some other laws came into force by being published in the Official Gazette with number 28261 on 11th April, 2012. Social Studies was continued to be implemented in the 5, 6, 7 and 8th grades as a major area course in the 4+4+4 education system. The changes and innovations that are performed in the program have created different effects on the administrators, the teachers and the students at the schools. In this research, it was aimed to determine the opinions of the social studies teachers about the chaotic situations caused by innovations and changes experienced in social studies. The Research is a special case study conducted with the qualitative research approach. As a result, teachers who participated in the survey evaluated the positive and negative aspects of the 4+4+4 education system application. It is determined that the teachers who find the system negative had chaotic situations about student’s age, physical environment, application-guidance, harmony wih school, continuity of the system öngörülemeand administration problems. It is concluded that in social studies teaching, teachers had chaotic situations because of deficiency of the program, inadequate time of lessons causing not to catch up with the scheduled time, harmony problems of the students who begin the secondary school just after the fourth grade and students’ insufficiency in cognitive and sensual developmental levels of readiness. It is determined that students had chaotic problems caused by the change of their physical environment, leaving their friends and leaving their class teacher while trying to adapt to their new branch teacher. It is determined that these results made the teachers face chaotic and complex situations and caused them not to be able to foresee the future.

  2. Towards a conceptual model of motorcyclists' Risk Awareness: a comparative study of riding experience effect on hazard detection and situational criticality assessment.

    2012-11-01

    This research investigates risk awareness abilities among different populations of motorcyclists. Risk awareness is defined here as an extension of the Situational Awareness theory applied to critical driving situations. This study is more particularly focused on two main cognitive abilities supporting risk awareness: hazard detection, corresponding to riders' skill to perceive critical event occurring in the road environment and to identify it as a threat, and situational criticality assessment, corresponding to a subjective assessment of the accident risk. From this theoretical framework, the aim is to compare motorcyclists' performances in risk awareness according to their experience in motorcycling. Four populations of motorcyclists are investigated: Professional (Policemen), Experienced riders, Novices, and Beginners. Method implemented is based of a set of 25 video sequences of driving situations presenting a risk of collision. Participants' task was firstly to stop the video film if they detect a hazard. Then, at the end of each sequence, they have also to assess the criticality of the driving situation as a whole, with a Likert scale (from 0 to 100% of criticality). Results obtained show that cognitive abilities in both (i) hazard detection and (ii) situational criticality assessment depend of the riding experience, and are learnt from two different timing. On one side, Professional and Experienced riders obtained better results than Novices and Beginners for hazard perception (i.e. shortest reaction time). In terms of situational criticality assessment, Beginners underestimate the situational risk and seem overconfident in their abilities to manage the situational risk, against Novices, Professional and Experienced riders, who have better competences in criticality assessment. From these empirical results, a conceptual model of motorcyclists' Risk Awareness is proposed. Copyright © 2011 Elsevier Ltd. All rights reserved.

    The purpose of this study was to analyse whether the parallel life situation between stroke patients and their informal caregivers (dyads) shown in cross-sectional studies prevails also in a longitudinal perspective. A total of 377 Swedish stroke patients, aged ≥ 65 years, and their 268 informal caregivers were followed from hospital admission and one year on. Analyses were based on patient interviews, functional ability (MMSE) score, Nottingham Health Profile (NHP) score, Hospital Anxiety and Depression (HAD) score, self-rated health score, and the Gothenburg Quality of Life (GQL) activity score. Similar information was obtained by postal questionnaires from informal caregivers, also including information on the nature and amount of assistance provided and on Caregiver Burden (CB) score. Before index admission informal caregivers provided care on average 5 h per week and after discharge 11 h per week (P caregiver relation, and short distance to patient's home. Significant positive associations within the dyads were found for HAD anxiety score (P caregiver relationship. CB score increased with amount of informal caregiver support, patient's age, and with low functional ability and low amount of municipal social service support. All these associations were constant across time. There was an association within the dyads regarding anxiety score, NHP score, and activity score. CB score was generally high.

  5. Vacant hospitals and under-employed nurses: a qualitative study of the nursing workforce management situation in Nepal.

    2015-04-01

    It is vital for all healthcare systems to have a sufficient number of suitably trained health professionals including nurses at all levels of health services to deliver effective healthcare. An ethnographic, qualitative method was chosen for this study, which included open-ended, in-depth interviews with a range of stakeholders including student nurses, qualified nurses, nurse managers and lecturers, and the human resource co-ordinator in the Ministry of Health and Population. Available records and policy documents were also analysed. Study findings suggest that there is a severe mal-distribution of the nursing workforce in rural and urban healthcare centres in Nepal. Although there is an oversupply of newly qualified nurses in hospitals in Kathmandu, the staffing situation outside the valley is undesirable. Additionally, the turnover of junior nursing staff remains high in major urban hospitals. Most qualified nurses aspire to work in developed countries, such as the UK, North America, Australia and New Zealand. Between 2000 and 2008, as many as 3000 nurses have left Nepal for jobs in the developed west. There is no effective management strategy in place to retain a nursing workforce, particularly in rural Nepal. This article concludes by proposing some suggestions for a nursing workforce retention policy to address this critical issue.

    Full Text Available In China, the prevalence of hypertension is increasing and is showing an epidemic accelerating trend. However, there is a lack of studies reporting the hypertension status of rural residents with minimum living allowances. We performed a cross-sectional study including 11,435 (5285 men and 6150 women from the general population aged ≥35 years in the Liaoning Province of China from 2012 to 2013, of which 1258 (11.0% participants came from minimal assurance families. Anthropometric measurements, laboratory examinations and self-reported lifestyle factor information were collected by trained personnel. Multivariate logistic regression was used to detect the association between socioeconomic status (SES and the risk of hypertension. We found that the prevalence of hypertension was as high as 61.9% in participants from minimal assurance families and the odd ratio for hypertension was 1.32 (95% CI: 1.15–1.52. The awareness, treatment, and control rates among treated hypertensive participants did not increase with higher level of income and education. In the total sample, the lower income levels increased the risk for hypertension, but education didn’t show a significant association with hypertension. Thus, there is a severe hypertension situation in the Liaoning rural population of minimal assurance families, which need more attention and prevention and control measures for hypertension.

    1994-01-01

    Several studies indicate that stress is inherently present in dental practice. The present study was conducted to help identify the factors underlying this stress and the relative contribution of each factor. A questionnaire presented participating dentists with 52 potentially-stressful situations related to dental practice. Respondents were asked to rate each situation on a five-point scale, using a range of responses that varied from "not stressful" to "exceedingly stressful," and "I don't know" to "not applicable." The present data are based on the ratings given by the 1,332 dentists practicing in Québec who answered the questionnaire (52 per cent). Ten situations received a mean score of greater than 3.0, and were therefore considered as above average stress-producing situations. The majority of these situations could be classified as being related either to dental procedures and office organization or to interpersonal relationships involving patients and/or office personnel. It was found that the older age groups showed significantly less stress for six of the 10 most stressful situations. This study has indicated the specific situations that most frequently lead to stress in dentists. The precise identification of these situations could lead to reduced stress through the elimination of its vague and insidious character. Furthermore, an understanding of the most common stress-causing situations allows the practitioner to take preventive measures to eliminate its damaging effects in the dental practice.

    The combined heat and power (CHP) is in addition to renewable energy and energy efficiency a cornerstone for the transformation of the energy sector towards greater climate and environmental friendliness. Due to the situation in the energy markets currently plants operated with natural gas have come under pressure. Against the background of the critical economic situation of many gas-based cogeneration plants, it is therefore necessary, with a new combined heat and power law (CHP) to provide planning security for the plant operator. Meanwhile, there is a government draft of the Combined Heat and Power Generation Act in 2016, which includes far-reaching changes for the CHP. This article summarizes the most important changes. [German] Die Kraft-Waerme-Kopplung (KWK) ist neben den erneuerbaren Energien und der Energieeffizienz einer der Eckpfeiler fuer die Transformation des Energiesektors hin zu mehr Klima- und Umweltfreundlichkeit. Aufgrund der Situation auf den Energiemaerkten sind aber gerade mit Erdgas betriebene Anlagen unter Druck geraten. Vor dem Hintergrund der wirtschaftlich kritischen Situation vieler gasbasierter KWK-Anlagen gilt es daher, durch ein neues Kraft-Waerme-Kopplungs-Gesetz (KWKG) Planungssicherheit fuer die Anlagenbetreiber zu schaffen. Inzwischen liegt ein Regierungsentwurf zum KWKG 2016 vor, der weitreichende Aenderungen fuer die KWK beinhaltet. Dieser Artikel fasst die wichtigsten Aenderungen zusammen.

  10. When care situations evoke difficult emotions in nursing staff members: an ethnographic study in two Norwegian nursing homes.

    2015-01-01

    Caring practice in nursing homes is a complex topic, especially the challenges of meeting the basic needs of residents when their behaviour evokes difficult emotions. Cognitive and physical changes related to aging and disability can contribute to behaviours considered to be unacceptable. For example, resident behaviours such as spitting, making a mess with food or grinding teeth are behaviours that most people do not want to see, hear or experience. The aim of this study was to gain a deeper understanding of how nursing home staff members deal with such behaviours in care situations. This article draws on ethnographic data to describe how nursing home staff members manage unpleasant resident behaviours. The study was based on two long-term units in two Norwegian public nursing homes. The Region's Medical Ethics Committee and the Norwegian Social Science Data Services granted approval. In total, 45 participants (37 nursing aides and eight nurses) agreed to participate in this study. Ten of the participants were interviewed at the end of the field study. This study indicates that nursing home staff members experience difficult emotions related to some residents' behaviours. However, they found these feelings difficult to express and rarely verbalized them openly. In addition, they were characterized by a strong obligation to help all residents, despite their own feelings. Therefore, it appears that an inner struggle occurs as a part of everyday practice. Despite these difficult emotions, nursing staff members believed that they needed to manage their responses and continued to offer good care to all residents. These findings extend our understanding of this unarticulated part of nursing home practice.

    Recent studies show that both adults and young children possess powerful statistical learning capabilities to solve the word-to-world mapping problem. However, the underlying mechanisms that make statistical learning possible and powerful are not yet known. With the goal of providing new insights into this issue, the research reported in this paper used an eye tracker to record the moment-by-moment eye movement data of 14-month-old babies in statistical learning tasks. Various measures are applied to such fine-grained temporal data, such as looking duration and shift rate (the number of shifts in gaze from one visual object to the other) trial by trial, showing different eye movement patterns between strong and weak statistical learners. Moreover, an information-theoretic measure is developed and applied to gaze data to quantify the degree of learning uncertainty trial by trial. Next, a simple associative statistical learning model is applied to eye movement data and these simulation results are compared with empirical results from young children, showing strong correlations between these two. This suggests that an associative learning mechanism with selective attention can provide a cognitively plausible model of cross-situational statistical learning. The work represents the first steps in using eye movement data to infer underlying real-time processes in statistical word learning.

    Kodaikkanal, India, suffered mercury contamination due to emissions and waste from a thermometer factory. Kodai Lake is situated to the north of the factory. The present study determined mercury in waters, sediment and fish samples and compared the values with those from two other lakes, Berijam and Kukkal. Total mercury (Hg(T)) of 356-465 ng l(-1), and 50 ng l(-1) of mercury in methyl mercury form were seen in Kodai waters while Berijam and Kukkal waters showed significantly lower values. Kodai sediment showed 276-350 mg/kg Hg(T) with about 6% methyl mercury. Berijam and Kukkal sediments showed Hg(T) of 189-226 mg/kg and 85-91 mg/kg and lower methylation at 3-4% and 2%, respectively. Hg(T) in fish from Kodai lake ranged from 120 to 290 mg/kg. The results show that pollution of the lake has taken place due to mercury emissions by the factory.

    About 40% of patients with obsessive-compulsive disorder (OCD) are said to have treatment-refractory symptoms and chronic course of illness in spite of cognitive-behavior therapy and pharmacotherapy. The present purpose was to investigate factors relevant to OCD patients' chronic course and disturbed daily functions in view of human basic needs based on Maslow's hierarchy of five basic needs. Case notes of 101 outpatients with OCD (47 men and 54 women who were 18 to 55 years old) and seen on a psychiatry unit of a general hospital were studied to explore their stressful situations and identify thwarted basic needs. 84 of the 101 patients had Love Needs, and Esteem Needs (n = 47) and Safety Needs (n = 45) were next. The Poor-functioning group mainly had histories with problems of Safety Needs (70.8%), while the Good-functioning group tended to mainly have problems of Esteem Needs (51.5%) rather than Safety Needs (33.3%). 57 patients (23 men and 34 women) who were treated for more than three months were divided into two groups according to their Global Assessment of Functioning score at the final assessment (cut-off point: 61); patients in the Good-functioning group tended to have problems of higher needs.

    Full Text Available The world is going through rapid changes and the companies seek alternatives to improve its products and processes and maintain their competitiveness. One alternative is the implementation of programs of quality management that combine human’s and technical’s factors. Six Sigma has gained evidence on the last years because aggregate tools and methodology. However, all quality program factors need management. The main goal of this paper is classify what assignments of Human Resource Management can contribute to reduction of the difficulties that can be encountered on implementation and maintenance of Six Sigma program in companies that was situated in the Rio Grande do Sul. For carry this work was necessary contact companies of the Rio Grande do Sul that use this program and was applied one questionnaire to classify the contribution of the Human Resource Management for the success of Six Sigma. The statistical tools, contents analyze, tables of relationship and qualitative analysis were applied for analysis. It’s evidence in this research the existence of potentials difficulties of Six Sigma listed in the literature and the influence that some assignments of Human Resource Management can be for solve this difficulties. The result of the research indicate that the participative and compromised leadership and the clear and objective communication of program are the assignments of Human Resource Management among the studied that more contribute for reduction of the difficulties of Six Sigma in the companies of this research.

Objective: To analyze the ASHAs’ practice with respect to CCSP in related situations. Study design: Cross-sectional study. Study location: Chiraigaon Community Development Block, Varanasi Material and method: 173 out of the total 240 ASHAs (~72% in the selected Chiraigaon Community Development Block of Varanasi were randomly selected and interviewed using a pre-designed and pre-tested questionnaire pertinent to CCSP. Only the first response was recorded. Results: All the ASHAs interviewed claimed that the CCSP training has helped them perform better in the community. Ninety-eight percent of the ASHAs knew that a new born weighing >2.5 kgs at birth is considered to be normal. Only ~ 63% (109 of the ASHAs were found to be home-visiting such newborns as per the CCSP recommendation. The percentage was found to be just 43% for the properly scheduled home visits of LBW newborns. The difference was found to be statistically significant (p<0.001. Almost 80% ASHAs estimated that their average home visit spans for at least 30 minutes. Just about a third of the interviewees suggested that a baby should be bathed only after the first 6 days while one-third said that they advise massaging for the newborn only after the first week. ASHAs rarely used a thermometer to assess the baby’s temperature. Around 56% were confident about using a thermometer. Nearly 90% participants claimed of explaining about Kangaroo Mother Care to the parturient and/or family. Majority of the ASHAs (92% emphasized upon non-discontinuation of breast feeding for the baby during diarrhoeal episodes. However, only 44% revisited such babies. Conclusion: In most cases it is well evident that CCSP training has been taken up well by the ASHAs. The training may be refreshed.

    Based on the frameworks of dual-process theories, we examined the interplay between intuitive and controlled cognitive processes related to moral and social judgments. In a virtual reality (VR) setting we performed an experiment investigating the progression from fast, automatic decisions towards more controlled decisions over multiple trials in the context of a sacrificing scenario. We repeatedly exposed participants to a modified ten-to-one version and to three one-to-one versions of the trolley dilemma in VR and varied avatar properties, such as their gender and ethnicity, and their orientation in space. We also investigated the influence of arousing music on decisions. Our experiment replicated the behavioral pattern observed in studies using text versions of the trolley dilemma, thereby validating the use of virtual environments in research on moral judgments. Additionally, we found a general tendency towards sacrificing male individuals which correlated with socially desirable responding. As indicated by differences in response times, the ten-to-one version of the trolley dilemma seems to be faster to decide than decisions requiring comparisons based on specific avatar properties as a result of differing moral content. Building upon research on music-based emotion induction, we used music to induce emotional arousal on a physiological level as measured by pupil diameter. We found a specific temporal signature displaying a peak in arousal around the moment of decision. This signature occurs independently of the overall arousal level. Furthermore, we found context-dependent gaze durations during sacrificing decisions, leading participants to look prolonged at their victim if they had to choose between avatars differing in gender. Our study confirmed that moral decisions can be explained within the framework of dual-process theories and shows that pupillometric measurements are a promising tool for investigating affective responses in dilemma situations.

    In recent years, there has been an increased research focus on adolescent and young adult (AYA) cancer patients. Few longitudinal studies have taken into consideration the specifics of their life situation and the status of psychosocial care services for this population. Our ongoing study aims to determine the psychosocial life and supportive care situation of AYA cancer patients, to describe risk groups, and to develop recommendations for their psycho-oncological care and support. The AYA-Leipzig study (AYA-LE) is a German prospective, longitudinal, study examining AYAs´ life situation (e.g. psychological distress, quality of life) and psychosocial care (e.g. evaluation and preferences, support needs) using two measurement points, namely, upon acute treatment completion (baseline) and 12 months later. N = 577 AYA cancer patients aged between 18 and 39 years at diagnosis, and representing all major tumor entities fill out a standardized questionnaire (online or by post), mainly based on validated instruments. AYA-specific concerns (e.g. family planning, sexual and reproductive health, social support, health behavior) will explicitly be considered. Participants are recruited in 16 German acute care hospitals, four rehabilitation clinics, and from two German state tumor registries. In summary, our longitudinal study will create a large database encompassing all malignant tumor entities and including detailed information about the distress and quality of life, specific problems, and specific support needs of AYA cancer patients at two different points in time post-diagnosis. The information we gather about existing psychosocial care and patient preferences and desires concerning psycho-oncological care will be used to develop recommendations for psycho-oncological care providers.

    After disasters, the disaster medical assistance team composed of skilful healthcare staff should be available at the disaster site for providing care to disaster's victims. It is believed that midwives are at the front line of the disaster management team and should be prepared for providing care to mothers and children. To investigate the midwifery students' basic educational needs for taking the role of an assistant in disaster situations. A cross-sectional study was conducted in an urban area of Iran, in year 2015. Two hundred and thirty-one final-year midwifery students with bachelor and master degrees in midwifery participated in this study. The samples were chosen using a census method from four nursing and midwifery schools affiliated with four medical sciences universities in Tehran, Iran. The informed consent form was signed by the samples before data collection. The samples were asked to fill out the researcher's made questionnaires consisting of the demographic data form and the basic educational needs for taking the role of an assistant in disaster situations. The later was consisted of two parts: 'coping with disaster situations' and 'performing the triage'. The data were analysed using descriptive and inferential statistics via the SPSS software for Windows. The mean score of coping with disaster situations was 31.3±8.2 (out of 45). Also, the mean score of performing the triage was 14.6±11.8 (out of 20). It was found that 68.8 and 74% of the students in coping with disaster situations and performing the triage, respectively had high and very high educational needs. The highest educational need was reported in the areas of 'time management' and 'the use of equipment in disaster situations'. About 86.8% of the students declared that academic education did not prepared them for taking roles in disaster situations. Only 10.6% passed educational courses about disasters before and 11.5% had the work experience in disaster situations. There was a

    Full Text Available This study aims to examine the effect of government internal auditors moral levels and situational pressures on the tendency to commit fraud when conducting audit. Based on the hypothesis, despite the situational pressures, the government internal auditors who have a high moral level will not commit fraud at the time of auditing. Meanwhile, the government internal auditors who have a low moral level will com-mit fraud at the time of auditing when there is situational pressure. To test the hypothesis, a 22 factorial experiment is conducted involving 68 students of STAR-BPKP of Jenderal Soedirman University. The results indicate that the government internal auditors who have a high moral level will not commit fraud in the time of auditing despite some situational pressures. Meanwhile, the government internal auditors who have a low moral level will commit fraud at the time of auditing either there is a situational pressure or not. The implications of this study are to streng-then the supervisory system for the internal auditors at the time of auditing, to provide protection for whistle- blowers who report the presence of fraud committed by auditors, and to be consistent in giving reward to professional auditors and pu-nishment to auditors who are convicted of fraud at the time of auditing.

    2007-01-01

    Full Text Available With the aim of bring near to the spanish academic field the european approaches of Public Relations, this article makes a compared revision of the situation of this subject and profession in Germany and Spain. This revision shows important resemblances on the use of the term “public relations”, the confusion of this subject with other communicative activities, the professional development and the problems of the field in both countries. However, it also shows that Germany has more tradition on public relations research than Spain and, therefore, it has a more extensive corpus of theories about this subject. For this reason, since important resemblances exist in other aspects, german research on public relations could be interesting for the spanish academic field both to explain the situation of public relations in Spain and to motivate theoretical development in our country.

    Full Text Available Abstract Background African highlands often suffer of devastating malaria epidemics, sometimes in conjunction with complex emergencies, making their control even more difficult. In 2000, Burundian highlands experienced a large malaria outbreak at a time of civil unrest, constant insecurity and nutritional emergency. Because of suspected high resistance to the first and second line treatments, the provincial health authority and Médecins Sans Frontières (Belgium decided to implement vector control activities in an attempt to curtail the epidemic. There are few reported interventions of this type to control malaria epidemics in complex emergency contexts. Here, decisions and actions taken to control this epidemic, their impact and the lessons learned from this experience are reported. Case description Twenty nine hills (administrative areas were selected in collaboration with the provincial health authorities for the vector control interventions combining indoor residual spraying with deltamethrin and insecticide-treated nets. Impact was evaluated by entomological and parasitological surveys. Almost all houses (99% were sprayed and nets use varied between 48% and 63%. Anopheles indoor resting density was significantly lower in treated as compared to untreated hills, the latter taken as controls. Despite this impact on the vector, malaria prevalence was not significantly lower in treated hills except for people sleeping under a net. Discussion Indoor spraying was feasible and resulted in high coverage despite being a logistically complex intervention in the Burundian context (scattered houses and emergency situation. However, it had little impact on the prevalence of malaria infection, possibly because it was implemented after the epidemic's peak. Nevertheless, after this outbreak the Ministry of Health improved the surveillance system, changed its policy with introduction of effective drugs and implementation of vector control to prevent new

    Background: The most important factors for prognosis of cervical cancers are age and histological criteria such as the tumor size, the involvement of lymph nodes, lympho-vascular space involvement as well as microvessel involvement and poor tumor differentiation (grading 3). Here we present the results of concomitant chemo-radiation at high-risk situation of patients with cervical cancer after surgery. Patients and Methods: The study comprised 34 patients with median age of 40 years (26-63 years) after Wertheim surgical technique for cervical cancer at the FIGO Stages IB (n = 19) and IIB (n = 15). All patients were treated between November 1995 and June 1999 by a schedule of concomitant chemoradiation. The indication for this treatment was given by the positive histological proof of lymph node metastasis, microvessel or lympho-vascular space involvement as well as a G3 grading. The chemo-therapy was given in week 1 and 5 (day 1-5 and day 29-33). The dosage of cisplatin was 20 mg/m{sup 2}/d on every day and 5-FU was given as a 120-h infusion with 600 mg/m{sup 2}/d. The external beam radiotherapy was applied to the pelvis with 1.8 Gy per fraction up to 50.4-54 Gy. In two patients the paraaortal region was irradiated too because of the involvement of these lymph nodes. Results: The median observation time was 48 months (3-68 months). 30 patients are alive (88%) in complete response. Four patients died. The mean survival was 61 {+-} 3 months. We have seen only slight acute toxicities of grade 1 and 2. Three patients suffered from a grade 3 diarrhea and three patients developed a grade 3 leukopenia. In seven patients we found a secondary lymphedema as a late toxicity. Conclusion: The concomitant chemoradiation containing cisplatin in high-risk situation for cervical cancer after surgery improves the outcome and survival in these patients. (orig.)

    We present an overview of a mission concept named Situational Awareness Sensor Suite for the ISS (SASSI) with a special focus here on low-latitude ionospheric plasma turbulence measurements relevant to equatorial spread-F. SASSI is a suite of sensors that improves Space Situational Awareness for the ISS local space environment, as well as unique ionospheric measurements and support active plasma experiments on the ISS. As such, the mission concept has both operational and basic research objectives. We will describe two compelling measurement techniques enabled by SASSI's unique mission architecture. That is, SASSI provides new abilities to 1) measure space plasma potentials in low Earth orbit over ~100 m relative to a common potential, and 2) to investigate multi-scale ionospheric plasma turbulence morphology simultaneously of both ~ 1 cm and ~ 10 m scale lengths. The first measurement technique will aid in the distinction of vertical drifts within equatorial plasma bubbles from the vertical motions of the bulk of the layer due to zonal electric fields. The second will aid in understanding ionospheric plasma turbulence cascading in scale sizes that affect over the horizon radar. During many years of ISS operation, we have conducted effective (but not perfect) human and robotic extravehicular activities within the space plasma environment surrounding the ISS structure. However, because of the complexity of the interaction between the ISS and the space environment, there remain important sources of unpredictable environmental situations that affect operations. Examples of affected systems include EVA safety, solar panel efficiency, and scientific instrument integrity. Models and heuristically-derived best practices are well-suited for routine operations, but when it comes to unusual or anomalous events or situations, there is no substitute for real-time monitoring. SASSI is being designed to deploy and operate a suite of low-cost, medium/high-TRL plasma sensors on

Despite accumulating evidence of its value in reducing many different kinds of crime - such as burglary, fraud, robbery, car theft, child sexual abuse and even terrorism - little has previously been published about its role in reducing organised crimes. This collection of case studies, by a distinguished international group of researchers, fills this gap by documenting the application of a situational pre...

    While previously available methodologies for software ? like those published in the early days of object technology ? claimed to be appropriate for every conceivable project, situational method engineering (SME) acknowledges that most projects typically have individual characteristics and situations. Thus, finding the most effective methodology for a particular project needs specific tailoring to that situation. Such a tailored software development methodology needs to take into account all the bits and pieces needed for an organization to develop software, including the software process, the

    To investigate the situation regarding the cleaning and sterilization of endonasal endoscopes in department of otolaryngology in Hunan Province, and to provide strategy for improving the level of sterilization and management of endonasal endoscopes.
 A total of 100 medical institutions were investigated by spot assessment, check and sampling. Data was analyzed by multivariate analysis.
 The qualified rate of rules and regulations for endoscopy was 28.8% in the second-class hospitals and 45% in the top-class hospitals. The qualified rate of environment for endoscopy cleaning and sterilization was 36.3% in the second-class hospitals and 85% in the top-class hospitals. The main problems include lack of independent disinfection room, the space not large enough, and/or lack of ventilation system. The qualified rate of bacterial detection for post-sterilized endoscopes and biopsy forceps was 93.8% in the second-class hospitals and 95.0% in the top-class hospitals, and the main pathogenic bacteria was gram-positive cocci and gram-negative bacilli. The multivariate analysis showed that the influencial factors for endoscope cleaning and disinfection are as follows: staffs responsible for the cleaning and sterilization of otolaryngology endoscopes, the standard for cleaning and disinfection process, and the frequency of endoscope use.
 The present situation of cleaning and sterilization for otolaryngology endoscopes is better in the top-class hospitals than that in the second-class hospitals. The sterilization and management of otolaryngology endoscopy are needed to be improved, and the staff training is needed, especially in the primary hospitals.

    To develop and validate a modified Situation-Background-Assessment-Recommendation communication tool incorporating components of the Cape Town modified early warning score vital signs chart for reporting early signs of clinical deterioration. Reporting early signs of physiological and clinical deterioration could prevent "failure to rescue" or unexpected intensive care admission, cardiac arrest or death. A structured communication tool incorporating physiological and clinical parameters allows nurses to provide pertinent information about a deteriorating patient in a logical order. Mixed methods instrument development and validation. We used a sequential three-phase method: cognitive interviews, content validation and inter-rater reliability testing to validate a self-designed communication tool. Participants were purposively selected expert nurses and doctors in government sector hospitals in Cape Town. Cognitive interviews with five experts prompted most changes to the communication tool: 15/42 (35.71%) items were modified. Content validation of a revised tool was high by a predetermined ≥70% of 18 experts: 4/49 (8.2%) items were modified. Inter-rater reliability testing by two nurses indicated substantial to full agreement (Cohen's kappa .61-1) on 37/45 (82%) items. The one item achieving slight agreement (Cohen's kappa .20) indicated a difference in clinical judgement. The high overall percentage agreement (82%) suggests that the modified items are sound. Overall, 45 items remained on the validated tool. The first modified early warning score-linked Situation-Background-Assessment-Recommendation communication tool developed in South Africa was found to be valid and reliable in a local context. Nurses in South Africa can use the validated tool to provide doctors with pertinent information about a deteriorating patient in a logical order to prevent a serious adverse event. Our findings provide a reference for other African countries to develop and validate

    Lystbæk, Christian Tang

    The purpose of this paper is to examine ways to situate management within philosophy, that is, ways to analyze the philosophical assumptions in management history, theory and practice. Since Burrell and Morgan suggested the idea that “all theories of organization are based upon philosophy...... of science“ (Burrell & Morgan, 1979:1), philosophical reflections in terms of a series of “isms” informed by different schools or paradigms (such as positivism, structuralism, phenomenology, critical theory, and so on and so forth) have been a central part of management studies. Thus, today, it has become...... common sense to categorize different approaches to management according to their assumptions of ontology, epistemology and methodology.

    The purpose of this study is to clear up the difference between Asperger's disorder (AS) and high functioning autism (HFA) with a newly developed test, the metaphor and sarcasm scenario test (MSST) can be used to distinguish pervasive developmental disorder (PDD) from attention deficit/hyperactivity disorders (AD/HD). So 66 AS children, 20 HFA children and 37 AD/HD children were selected, compared the profiles of score on the MSST. The results showed that the inability to understand sarcastic situation was specific to group with AS, both group with HFA and AD/HD were differ little to understand between metaphor and sarcasm. In this study suggest differences in situational recognition among the PDD subtypes, the clinical symptoms of PDD reflects characteristics of AS.

    Situation awareness (SA)-the perception of data elements, comprehension of their meaning and projection of their status in the near future-has been associated with human performance in high-risk environments, including aviation and the operating room. The influences on SA in inpatient medicine are unknown. We conducted seven focus groups with nurses, respiratory therapists and resident physicians using a standardised semistructured focus group guide to promote discussion. Recordings of the focus groups were transcribed verbatim, and transcripts were qualitatively analysed by two independent reviewers to identify convergent and divergent themes. Three themes emerged: (1) team-based care, (2) availability of standardised data and (3) standardised processes and procedures. We categorised these into social, technological and organisational influences on SA. Subthemes that emerged from each focus group were shared language to describe at-risk patients, provider experience in critical care/deterioration and interdisciplinary huddles to identify and plan for at-risk patients. An objective early warning score, proactive assessment and planning, adequate clinician staffing and tools for entering, displaying and monitoring data trends were identified by six of seven groups. Our data better reflected the concepts of team SA and shared SA than individual SA. Team-based care and standardisation support SA and the identification and treatment of patient risk in the complex environment of inpatient care. These findings can be used to guide the development and implementation of targeted interventions such as huddles to proactively scan for risk and electronic health record displays of data trends.

  6. A new lens for supporting and studying science teacher reflections: situating the self in the [activity] system

    2015-12-01

    This paper presents a new lens for analyzing written reflections on the teaching experiences of pre-service [science] teachers. The lens, which borrows heavily from Activity Theory, allows science education researchers and teacher educators to identify tensions, disturbances, conflicts, and contradictions within teachers' written reflections as a means to help the participants situate their successes and challenges within the activity systems in which they operate. This paper describes the process through which the lens was crafted, defines the key constructs comprising the lens, applies the lens to the analysis of two purposefully selected reflection documents, and then considers the affordances of the lens. It also discusses how the insights gained from this lens have lead to new ways of facilitating reflection in pre-service science teachers, including the use of Kenneth Snelson's tensegrity sculptures as a metaphor for the goal of reflection. Finally, it connects the tensions identified in the individual reflections of two pre-service science teachers to broader issues being addressed in science education.

This study is concerned with the impact of different economic environments - the crisis in Greece vs. the boom in Turkey - on compulsive buying tendencies of students, while taking the role of gender and available money into account. Methods: Compulsive buying was measured by a Greek and Turkish translation of the German Compulsive Buying Scale (Raab, Neuner, Reisch & Scherhorn, 2005) in Greece and Turkey, which enabled an identification of compulsive and compensatory buyers. The questionnaires were administered to 119 Turkish and 123 Greek students (n = 242) enrolled in several universities in Athens and Istanbul. The data collection was conducted in a controlled and standardized way, namely in group-sessions lasting about 5 minutes, which were conducted and supervised by co-workers of the involved universities. Results: The results have shown that the percentage of compensatory buyers, but not compulsive buyers, within the Greek students sample was significantly smaller than within the Turkish student sample. Further as assumed the moderation of the economic situation could be confirmed: More available money only has a facilitating effect on compulsive buying tendencies under a positive economic environment. Conclusions: Anticipations about the financial situation and the general economic climate are more relevant for compulsive buying tendencies than one’s actual available money.

    Full Text Available INTRODUCTION: Adherence to combination antiretroviral therapy (cART is vital for HIV-infected adolescents for survival and quality of life. However, this age group faces many challenges to remain adherent. We used multiple data sources (role-play, focus group discussions (FGD, and in-depth interviews (IDI to better understand adherence barriers for Rwandan adolescents. Forty-two HIV positive adolescents (ages 12-21 and a selection of their primary caregivers were interviewed. All were perinatally-infected and received (cART for ≥ 12 months. Topics discussed during FGDs and IDIs included learning HIV status, disclosure and stigma, care and treatment issues, cART adherence barriers. RESULTS: Median age was 17 years, 45% female, 45% orphaned, and 48% in boarding schools. We identified three overarching but inter-related themes that appeared to influence adherence. Stigma, perceived and experienced, and inadvertent disclosure of HIV status hampered adolescents from obtaining and taking their drugs, attending clinic visits, carrying their cARTs with them in public. The second major theme was the need for better support, in particular for adolescents with different living situations, (orphanages, foster-care, and boarding schools. Lack of privacy to keep and take medication came out as major barrier for adolescents living in congested households, as well the institutionalization of boarding schools where privacy is almost non-existent. The third important theme was the desire to be 'normal' and not be recognized as an HIV-infected individual, and to have a normal life not perturbed by taking a regimen of medications or being forced to disclose where others would treat them differently. CONCLUSIONS: We propose better management of HIV-infected adolescents integrated into boarding school, orphanages, and foster care; training of school-faculty on how to support students and allow them privacy for taking their medications.

    To identify challenging interpersonal interactions experienced by nursing and pharmacy students during clinical placement, and strategies used to manage those situations. Healthcare students and staff experience elevated stress when exposed to dynamic clinical environments, complex care and challenging professional relationships. Emotionally intelligent behaviours are associated with appropriate recognition and management of emotions evoked by stressful experiences and development of effective relationships. Nursing and pharmacy students' use of emotionally intelligent behaviours to manage challenging interpersonal situations is not well known. A qualitative design, using semi-structured interviews to explore experiences of challenging interpersonal situations during clinical placement (Phase two of a larger mixed-methods study). Final-year Australian university nursing and pharmacy students (n = 20) were purposefully recruited using a range of Emotional Intelligence scores (derived in Phase one), measured using the GENOS Emotional intelligence Inventory (concise version). Challenging interpersonal situations involving student-staff and intrastaff conflict, discourteous behaviour and criticism occurred during clinical placement. Students used personal and relational strategies, incorporating emotionally intelligent behaviours, to manage these encounters. Strategies included reflecting and reframing, being calm, controlling discomfort and expressing emotions appropriately. Emotionally intelligent behaviours are effective to manage stressful interpersonal interactions. Methods for strengthening these behaviours should be integrated into education of nursing and pharmacy students and qualified professionals. Education within the clinical/workplace environment can incorporate key interpersonal skills of collaboration, social interaction and reflection, while also attending to sociocultural contexts of the healthcare setting. Students and staff are frequently exposed

There is a consensus that the aggression phenomenon is multidimensional, but the picture is still unclear concerning the complex interplay of causal variables and their respective impact. To date, only a small number of empirical studies include users’ views of relevant factors. The main objective of this review is to identify and synthesize evidence relating to service users’ experiences and views of aggressive situations in mental health settings. Methods: We included qualitative studies of any design reporting on service users’ own experiences of conditions contributing to aggressive situations in mental health care and their views on preventative strategies. Eligible articles were identified through an electronic database search (PsycINFO, PubMed, Ovid Nursing Database, Embase, and CINAHL, hand search, and cross-referencing. Extracted data were combined and interpreted using aspects of thematic synthesis. Results: We reviewed 5,566 records and included 13 studies (ten qualitative and three mixed methods.

MÉTODOS: Fue realizada una encuesta en reunión organizada por la Sociedad Latinoamericana de Tórax. Cada editor presentó un reporte y respondió a un cuestionario. RESULTADOS: Mejora en la adquisición de informaciones es la principal motivaci��n para las sociedades de neumología para la edición de sus propias revistas, considerando que la diseminación de conocimiento médico y el reporte de experiencias son los principales motivos para que los autores envíen sus trabajos. El error más común en los trabajos enviados es la poca conformidad con las directrices de la revista. Mejorar las relaciones entre autor, editor y revisor sería la mejor estrategia para perfeccionar la calidad de los textos. Algunas sugerencias para mejorar las revistas latinoamericanas: promover profesionales en tareas editoriales; encorajar a los revisores a que sean más meticulosos; y adoptar normas internacionales para la edición de revistas médicas. Fueron reportados los siguientes problemas: falta de periodicidad adecuada y regular de las ediciones; una disminución en la cantidad de trabajos originales que son considerados ejemplares en la especialidad; baja tasa de rechazo de trabajos enviados; alta rotación de editores. CONCLUSIÓN: Podemos hacer las siguientes recomendaciones: a pesar de varias revistas estar en formato electrónico, ellas también deben ser mantenidas en formato impreso; cada revista debe informar su tasa de suscripción, aunque esté incluida en los gastos de inscripción anual; a pesar de cada país de Latinoamérica poder optar por publicar su propia revista, la posibilidad de publicación de una revista multinacional de neumología latinoamericana debe ser explotada.OBJECTIVE: To characterize the situation of pulmonology journals published in Latin America.

It should impart to their actions self image also as rules and regulatory guides to success. As technological oriented guide theory technology management aims at goal-directed utilization of engineering. Doing technology management demands to understand the definitions of technology and management. However engineering, technology and engineering science are not exactly to differentiate. Also it is difficult to classify engineering science. This book will contribute usefully on this and stimulate fruitfully the advancing discussions on the self image of science engineering.(GL) [Deutsch] Das vorliegende Buch richtet sich in erster Linie an Vertreter der Wirtschaft, Wissenschaft aber auch der Politik, die in ihrem Wirken fuer Technik verantwortlich sind.

    Decision-making (DM) in healthcare can be understood as an interactive process addressing decision makers' reasoning as well as their visible behaviour after the decision is made. Other key elements of DM are ethical aspects and the role as well as the treatment options of the examined professions. Nurses' DM to choose interventions in situations of severe breathlessness is such interactions. They are also ethically relevant regarding the vulnerability of affected patients and possible restrictions or treatment options. The study aims to explore which factors influence nurses' DM to use nursing interventions in situations where patients suffer from severe breathlessness. Qualitative study including nurses in German hospital wards and hospices. A triangulation of different methods of data collection-participant observation and qualitative expert interviews-and analysis merge in a reflexive grounded theory approach which integrates Goffman's framework analysis. It allows an analysis of nurses' self-statements about DM, their behaviour in relevant clinical situations and its influences. Data collection and analysis will be examined simultaneously. Informed consent will be gained from all participants and the institutional stakeholders. Ongoing consent has to be ensured since observations will take place in healthcare institutions and many patients will be highly vulnerable. The study has been evaluated and approved by the Witten/Herdecke University Ethics Committee, Witten, Germany. Results of the study will be published at congresses and in journal papers.

  7. The study on the evaluation of the pollution control situation of the sewage systems in the counties and cities of Taiwan by applying the VIKOR method.

    Kuo, Jun-Yuan

    2017-12-01

    Currently, the pollution control situation of the sewage systems across Taiwan can be divided into the two major sewage systems, namely, industrial area sewage and public community sewage. When the counties and cities of Taiwan cannot effectively control the sewage pollution situation, ecological pollution of the environment and personal health damage would result. Therefore, evaluating the pollution control situation of the sewage systems can help the environmental protection authorities developing strategies for the pollution control of the sewage systems in the future. In this study, the Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method was applied to evaluate the pollution control situation of the sewage systems. The water sample test qualification rate, the emission permit issuance rate, and the staff setting rate of the dedicated wastewater treatment company were used as the pollution control evaluation indexes. According to the results, the use of the VIKOR method to evaluate the pollution control situation of the sewage systems is effective. In cities and counties in Taiwan, public community sewage systems, dedicated to pollution control case, the public community should be actively coached in emission control technology to upgrade sewage capacity, the issuance of discharge permits, and the staff setting rate of the dedicated wastewater treatment, to improve public community sewage pollution control system capabilities. In Taiwan, the industrial area sewage systems, dedicated to pollution control situations, must pay attention to business units in raw materials, spare part inventory, and machine supplier of choice, and we must choose to meet environmental supply chain of green suppliers, which would be effective in reducing effluent produce and improve water sample test qualification rate. The VIKOR value of Yilan County is 1.0000, which is the worst in the pollution control of all the industrial area sewage systems, followed by Taoyuan

    This report, which relates the situation as of July 1997, again confirms the internationally leading role of the Federal German Republic in the phase-out of CFCs. No country has realised a more comprehensive concept for the phase-out of substances that deplete the ozone layer. Combining statutory and voluntary measures has proved a path-breaking approach. One of the most important driving forces in the CFC phase-out were the restrictions of use imposed by the Ordinance on the Prohibition of CFCs and Halon.

    Emergency responders need access to information but what counts as actionable information depends on their role, task, location, and other variables. For example, experts who have unique knowledge and experience and are called on to serve as scientific and teclmical responders, require correspondingly unique situation awareness in order to do their work. In our research-in-progress we leverage emerging and evolving web and digital library technologies to create personalized situation awareness tools that address the needs of these scientific and technical responders in real time, through focused information collection, extraction, integration, representation, and dissemination. We describe three personalized situation awareness tools in this paper: the Theme Awareness Tool (THEMAT), Social Awareness Tool (SAT), and Expertise Awareness Tool (EXPAT). The concepts and technologies we are developing in collaboration with experts apply to those who use the Web, in general, and offer an approach to the general issue of HCI design for emergencies.

  15. Situational pressures on aviation decision making: goal seduction and situation aversion.

    2009-06-01

    The context in which a decision is made can shape the decision process in important ways. Of particular interest here are 'strong' situations, that is, contexts where the situation itself exerts an influence on decision making. Borrowing concepts from field theory and approach/avoidance theory, this paper explores the influence of strong situations on pilot decision making. There were 28 pilots flying in Alaska who were interviewed using a critical incident technique where participants were asked to relate stories about challenging flying situations. A bottom-up qualitative analysis of reported social and psychological pressures revealed a range of types, including strong situations, which are described in this paper. Strong situations were mentioned in 67% of the interviews and included situations likely to motivate the pilot toward unsafe behavior (goal seduction) and situations likely to motivate the pilot away from safe behavior (situation aversion). Goal seduction situations included rescuing others, meeting a significant other, time-related constraints, financial pressures, and unspecified goal seduction; aversive situations included physical discomfort, not having maintenance or facilities for the airplane, and a lack of basic necessities (e.g., lodging) for the pilot. Goal seduction describes one broad, unspecified influence on pilot decision making, but situation aversion is also an important motivator for some pilots. Goal seduction and situation aversion may well underlie the phenomena of plan continuation errors, the tendency for pilots to continue despite evidence suggesting it is imprudent. This study suggests some specific factors that constrain decision making for pilots in challenging situations.

    This study investigated whether individualism and collectivism (IC) at country, individual, and situational level influence how quickly and accurately people can infer mental states (i.e. theory of mind, or ToM), indexed by accuracy and reaction time in a ToM task. We hypothesized that collectivism (having an interdependent self and valuing group concerns), compared to individualism (having an independent self and valuing personal concerns), is associated with greater accuracy and speed in recognizing and understanding the thoughts and feelings of others. Students (N = 207) from individualism-representative (the Netherlands) and collectivism-representative (Vietnam) countries (Country IC) answered an individualism-collectivism questionnaire (Individual IC) and were randomly assigned to an individualism-primed, collectivism-primed, or no-prime task (Situational IC) before performing a ToM task. The data showed vast differences between the Dutch and Vietnamese groups that might not be attributable to experimental manipulation. Therefore, we analyzed the data for the groups separately and found that Individual IC did not predict ToM accuracy or reaction time performance. Regarding Situational IC, when primed with individualism, the accuracy performance of Vietnamese participants in affective ToM trials decreased compared to when primed with collectivism and when no prime was used. However, an interesting pattern emerged: Dutch participants were least accurate in affective ToM trials, while Vietnamese participants were quickest in affective ToM trials. Our research also highlights a dilemma faced by cross-cultural researchers who use hard-to-reach populations but face the challenge of disentangling experimental effects from biases that might emerge due to an interaction between cultural differences and experimental settings. We propose suggestions for overcoming such challenges.

    The increasing number of people with dementia will challenge the health care system, especially acute care. Using health insurance claims data, the study objective was to examine the regional patterns of the administrative prevalence of dementia, the prevalence of dementia in hospitals and the care situation in hospitals. We used 2014 claims data from AOK PLUS, the largest statutory health insurance service in Saxony. If dementia was diagnosed either in an outpatient or inpatient setting in 3 of 4 quarters in a year, a person was categorised as a dementia case (n=61,700). The analysis of health care status included 61,239 patients with dementia and 183,477 control subjects. The control group was matched using the criteria of gender, age and region of residence. For those older than 65 years, the overall administrative prevalence rate of dementia was 9.3%. The estimated prevalence for those in hospitals was 16.7%. In 2014, there were 33% more admissions, 36% more hospital days and 18% higher costs per person-year among people diagnosed with dementia than the control subjects. The longer annual hospital stays and the higher costs were primarily caused by the greater number of admissions of people with dementia. Inpatient service use was, compared to people without dementia, characterized by a need for care and assistance, rather than by a need for medical therapeutic and diagnostic procedures. To improve the health care situation of people with dementia, to adapt to the challenges facing hospitals and to reduce the financial burden caused by dementia, more efforts are needed to improve the health care situation. Measures include, among others, improvements in recognition of dementia and reduction of unnecessary hospital stays. © Georg Thieme Verlag KG Stuttgart · New York.

Such an approach corresponds with the didactic concepts as laid down in the Bible itself as well as with the nature of human beings. In order to enable biblical texts to get a hearing that provides a “moment of freedom” (H.

    The behaviors of bystanders can have important effects on their peers. The aim of this study was to identify psychosocial and contextual factors associated with 3 types of bystander behavior (bully followers, outsiders, and defenders of victims) among Korean youth. A descriptive and cross-sectional study was conducted among 416 7th and 8th-grade students from 1 middle school in Korea. The Rosenberg Self Esteem Scale, the Korean version of the Social Problem-Solving Inventory, and measurements of relationships with friends and teachers, empathy, concerns about being bullied, attitudes toward bullying, and bystander behaviors were all used in the assessment. Empathy, relationship of teachers, attitudes toward bullying, and concerns about being bullied were significantly associated with all 3 types of bystanders' behaviors. Although, self-esteem, social problem solving ability were significantly associated with just defender of victim behaviors. These results suggest that several significant factors to cultivate constructive bystander behaviors should be considered to develop effective antibullying intervention.

    The sciences are often perceived by students as irrelevant as they do not see the content of science as related to their daily lives. Web 2.0-mediated activities are characterized by user-driven content production, collaboration, and multi-way communication. It has been proposed that employing Web 2.0 in educational activities will promote richer opportunities for making learning personally meaningful, collaborative, and socially relevant. Since Facebook is already in use among youths, it potentially provides a communicative link between educational content and students' lives. The present study was conducted as a case study to provide an inductive, explorative investigation of whether and how the integration of Facebook into upper secondary biology can affect interest in biology and participation in learning communication. The results indicate that the coupling of formal and informal communication practices on Facebook serves to maintain interest and open up new learning possibilities while at the same time creating barriers to communication. These barriers are due to distractions, ethical issues, and a certain depreciation of the activities ensuing from the everydayness of Facebook as a communication platform. In conclusion, use of Facebook as an educational platform is not clearly good or bad.

    Variability in patients' postoperative pain experience and response to treatment challenges effective pain management. Variability in pain reflects individual differences in inhibitory pain modulation and psychological sensitivity, which in turn may be clinically relevant for the disposition to acquire pain. The aim of this study was to investigate the effects of conditioned pain modulation and situational pain catastrophizing on postoperative pain and pain persistency. Preoperatively, 42 healthy males undergoing funnel chest surgery completed the Spielberger's State-Trait Anxiety Inventory and Beck's Depression Inventory before undergoing a sequential conditioned pain modulation paradigm. Subsequently, the Pain Catastrophizing Scale was introduced and patients were instructed to reference the conditioning pain while answering. Ratings of movement-evoked pain and consumption of morphine equivalents were obtained during postoperative days 2-5. Pain was reevaluated at six months postoperatively. Patients reporting persistent pain at six months follow-up (n = 15) were not significantly different from pain-free patients (n = 16) concerning preoperative conditioned pain modulation response (Z = 1.0, P = 0.3) or level of catastrophizing (Z = 0.4, P = 1.0). In the acute postoperative phase, situational pain catastrophizing predicted movement-evoked pain, independently of anxiety and depression (β = 1.0, P = 0.007) whereas conditioned pain modulation predicted morphine consumption (β = -0.005, P = 0.001). Preoperative conditioned pain modulation and situational pain catastrophizing were not associated with the development of persistent postoperative pain following funnel chest repair. Secondary outcome analyses indicated that conditioned pain modulation predicted morphine consumption and situational pain catastrophizing predicted movement-evoked pain intensity in the acute postoperative phase. These findings may have important

Pain was reevaluated at six months postoperatively.Patients reporting persistent pain at six months follow-up (n = 15 were not significantly different from pain-free patients (n = 16 concerning preoperative conditioned pain modulation response (Z = 1.0, P = 0.3 or level of catastrophizing (Z = 0.4, P = 1.0. In the acute postoperative phase, situational pain catastrophizing predicted movement-evoked pain, independently of anxiety and depression (β = 1.0, P = 0.007 whereas conditioned pain modulation predicted morphine consumption (β = -0.005, P = 0.001.Preoperative conditioned pain modulation and situational pain catastrophizing were not associated with the development of persistent postoperative pain following funnel chest repair. Secondary outcome analyses indicated that conditioned pain modulation predicted morphine consumption and situational pain catastrophizing predicted movement-evoked pain intensity in the acute postoperative phase.

    Virtual reality opens new opportunities for operator training in complex tasks. It lowers costs and has fewer constraints than traditional training. The ultimate goal of virtual training is to transfer knowledge gained in a virtual environment to an actual real-world setting. This study tested whether a maintenance procedure could be learnt equally well by virtual-environment and conventional training. Forty-two adults were divided into three equally sized groups: virtual training (GVT® [generic virtual training]), conventional training (using a real tank suspension and preparation station) and control (no training). Participants then performed the procedure individually in the real environment. Both training types (conventional and virtual) produced similar levels of performance when the procedure was carried out in real conditions. Performance level for the two trained groups was better in terms of success and time taken to complete the task, time spent consulting job instructions and number of times the instructor provided guidance.

    To determine the frequency of medication errors and incident types in a tertiary-care hospital emergency department. To quantify and classify medication errors and identify critical points where measures should be implemented to improve patient safety. Prospective direct-observation study to detect errors made in June and July 2016. The overall error rate was 23.7%. The most common errors were made while medications were administered (10.9%). We detected 1532 incidents: 53.6% on workdays (P=.001), 43.1% during the afternoon/evening shift (P=.004), and 43.1% in observation areas (P=.004). The medication error rate was significant. Most errors and incidents occurred during the afternoon/evening shift and in the observation area. Most errors were related to administration of medications.

    In northern Romania, there are numerous tailing ponds, resulting from mining activities that present significant environmental risks. Some of them, including Vrănicioara tailing pond, were the subject of technical projects for ecological rehabilitation. Vrănicioara pond is located on the right side of Cavnic Valley, downstream Cavnic town, about 4 kilometers far. It has about 500 m length and is located parallel to the road linking Baia Sprie and Cavnic localities. Chemical and physical stability of the tailing pond before rehabilitation interest the research, analysis and conclusions were published in several scientific meetings. In addition, close to the pond at less than 100 m, an open pit has developed, exploiting andesite by mining blast, increasing the risk of physical stability by continuous exposure to vibration. This activity currently continues, advancing towards the tailing pond body. The critical study addresses the current state of Vrănicioara Tailing Pond, analysis of some rehabilitation works done incorrectly, analysis of chemical stability that was not a priority during rehabilitation. Research intention is heading to water analysis confirming the existence of acid drainage that was not stopped or at least reduced. The scientific approach is based on the Technical Standards for Waste Deposits, in force in Romania, providing the rules to ensure physical and chemical stability.

    Assessing and understanding health systems governance is crucial to ensure accountability and transparency, and to improve the performance of mental health systems. There is a lack of systematic procedures to assess governance in mental health systems at a country level. The aim of this study was to appraise mental health systems governance in Nepal, with the view to making recommendations for improvements. In-depth individual interviews were conducted with national-level policymakers (n = 17) and district-level planners (n = 11). The interview checklist was developed using an existing health systems governance framework developed by Siddiqi and colleagues as a guide. Data analysis was done with NVivo 10, using the procedure of framework analysis. The mental health systems governance assessment reveals a few enabling factors and many barriers. Factors enabling good governance include availability of mental health policy, inclusion of mental health in other general health policies and plans, increasing presence of Non-Governmental Organizations (NGOs) and service user organizations in policy forums, and implementation of a few mental health projects through government-NGO collaborations. Legal and policy barriers include the failure to officially revise or fully implement the mental health policy of 1996, the existence of legislation and several laws that have discriminatory provisions for people with mental illness, and lack of a mental health act and associated regulations to protect against this. Other barriers include lack of a mental health unit within the Ministry of Health, absence of district-level mental health planning, inadequate mental health record-keeping systems, inequitable allocation of funding for mental health, very few health workers trained in mental health, and the lack of availability of psychotropic drugs at the primary health care level. In the last few years, some positive developments have emerged in terms of policy recognition for

    Disagreements and conflicts have a negative impact on the satisfaction and the performances of working team members. Young doctors in training are part of the health care team. The management of the disagreements with which they are confronted is a part of their professionalization process. To clarify and analyze the disagreements between GP trainees and their seniors in patients care and their consequences in doctor curriculum. Qualitative descriptive study. Five focus groups including a total of 25 Parisian trainees were performed to explore situations of disagreements with their seniors about patients care. Phenomenical analysis was performed by two researchers. Thirty-seven situations were reported. A number of potential sources of conflicts were highlighted. Factors that can transform a disagreement into an insoluble conflict were identified. The consequences of these disagreements on the quality of care and their impact on the empowerment of trainees were analysed. Number of disagreements related patients facing end of life. Specificities of emergency contexts and ambulatory practice were underlined. The role of the hierarchical link in the genesis and the development of the conflicts was confirmed. The personality of the trainee, his conception of responsibility, the exchange of knowledge, the "commercial" aspects of doctors practice can be at the origin of conflicts. The disagreements can play a positive role in trainees empowerment. A training in the management of anticipated or known conflicts can usefully clarify and optimize the hidden curriculum of the medical students towards professionalism.

  15. Using naturalistic driving study data to investigate the impact of driver distraction on driver's brake reaction time in freeway rear-end events in car-following situation.

    The rear-end crash is one of the most common freeway crash types, and driver distraction is often cited as a leading cause of rear-end crashes. Previous research indicates that driver distraction could have negative effects on driving performance, but the specific association between driver distraction and crash risk is still not fully revealed. This study sought to understand the mechanism by which driver distraction, defined as secondary task distraction, could influence crash risk, as indicated by a driver's reaction time, in freeway car-following situations. A statistical analysis, exploring the causal model structure regarding drivers' distraction impacts on reaction times, was conducted. Distraction duration, distraction scenario, and secondary task type were chosen as distraction-related factors. Besides, exogenous factors including weather, visual obstruction, lighting condition, traffic density, and intersection presence and endogenous factors including driver age and gender were considered. There was an association between driver distraction and reaction time in the sample freeway rear-end events from SHRP 2 NDS database. Distraction duration, the distracted status when a leader braked, and secondary task type were related to reaction time, while all other factors showed no significant effect on reaction time. The analysis showed that driver distraction duration is the primary direct cause of the increase in reaction time, with other factors having indirect effects mediated by distraction duration. Longer distraction duration, the distracted status when a leader braked, and engaging in auditory-visual-manual secondary task tended to result in longer reaction times. Given drivers will be distracted occasionally, countermeasures which shorten distraction duration or avoid distraction presence while a leader vehicle brakes are worth considering. This study helps better understand the mechanism of freeway rear-end events in car-following situations, and

    Limitation of life-sustaining treatment (LLST) is a recommended practice in certain circumstances. Limitation practices are varied, and their application differs from one center to another. The present study evaluates the current situation of LLST practices in patients with prolonged admission to the ICU who suffer worsening of their condition. A prospective, observational cohort study was carried out. Seventy-five Spanish ICUs. A total of 589 patients suffering 777 complications or adverse events with organ function impairment after day 7 of admission, during a three-month recruitment period. The timing of limitation, the subject proposing LLST, the degree of agreement within the team, the influence of LLST upon the doctor-patient-family relationship, and the way in which LLST is implemented. LLST was proposed in 34.3% of the patients presenting prolonged admission to the ICU with severe complications. The incidence was higher in patients with moderate to severe lung disease, cancer, immunosuppressive treatment or dependence for basic activities of daily living. LLST was finally implemented in 97% of the cases in which it was proposed. The decision within the medical team was unanimous in 87.9% of the cases. The doctor-patient-family relationship usually does not change or even improves in this situation. LLST in ICUs is usually carried out under unanimous decision of the medical team, is performed more frequently in patients with severe comorbidity, and usually does not have a negative impact upon the relationship with the patients and their families.

    Guérin, Eva; Fortier, Michelle S; Sweet, Shane N

    2013-04-18

    The nature of the association between physical activity and positive affect is complex, prompting experts to recommend continued examination of moderating variables. The main purpose of this 2-week field study was to examine the influence of situational motivational regulations from self-determination theory (SDT) on changes in positive affect from pre- to post- to 3-hours post-physical activity. Another purpose was to clarify the relationship between physical activity intensity [i.e., Ratings of Perceived Exertion (RPE)] and positive affect at the stated time points. This study employed an experience sampling design using electronic questionnaires. Sixty-six healthy and active, multiple-role women provided recurrent assessments of their physical activity, situational motivation, and positive affect in their everyday lives over a 14-day period. Specifically, measures were obtained at the three time points of interest (i.e., pre-, post-, 3-hours post-physical activity). The data were analyzed using multilevel modeling. Results showed that intrinsic motivation was related to post-physical activity positive affect while the influence of identified regulation appeared 3-hours post-physical activity. In addition, RPE, which was significantly predicted by levels of introjection, was more strongly associated with an increase in positive affect post-physical activity than three hours later. The theoretical implications of these findings vis-à vis SDT, namely in regards to a viable motivational sequence predicting the influence of physical activity on affective states, are discussed. The findings regarding the differential influences of RPE and motivational regulations carries applications for facilitating women's well-being.

    Unaccompanied minor refugees are children or adolescents below the age of 18 years who are not accompanied by their parents. International studies show that unaccompanied minor refugees represent a special risk group. Currently, empirical study results about the health status of unaccompanied minor refugees barely exist for Germany. Therefore, the goal of this article is an assessment of the health status and health care of unaccompanied minor refugees in Bielefeld, Germany. For this purpose, two qualitative studies and one quantitative study from Bielefeld are used.Results demonstrate that the health care of unaccompanied minor refugees underlies certain peculiarities that indicate major medical needs: Firstly, the need for psychological/psychiatric care and secondly the need for health care regarding infectious diseases. Further challenges in the health care needs of this population group result from its specific situation, and comprise legal conditions, as well as language and cultural competencies on behalf of the health care providers and the unaccompanied minor refugees themselves.

  4. Sizing Up the Situation

    2004-01-01

    Hailstorm damage to the Space Shuttle's External Tank inspired a NASA innovation with extensive photography applications. In order to measure the defects caused by the storm, Kennedy Space Center used telephoto lenses to zoom in on the tank and view the damage clearly. However, since there was no reference object in the image, the engineers could not determine the scale of the damage. In photographic situations similar to this, an object, such as a ruler, is placed within the field of view. This allows a person to look at a photograph and have a visual indication of the scale of the objects in it. In the External Tank situation, however, this procedure was not possible. As a solution, Kennedy developed the Scaling and Measurement Device for Photographic Images, which provides a non-intrusive means of adding a scale to a photograph. In addition to meeting Kennedy's needs, scaling images is extremely important in crime and accident scene investigations, oil and chemical tank monitoring, and aerial photography. The innovation consists of a tool that attaches directly to a camera or charge coupled device using a standard screw. Two lasers fitted to the device provide parallel beams that are set 1 inch apart. These lasers enable the device to project a pattern into the field of view. When a photograph is taken, the image of the laser pattern appears, along with the image of the object under investigation, allowing the viewer quantifiable information as to the size of the object. The laser beams are accurate to approximately 200 feet. Windows-based software was developed to work with the scaling device tool. The software provides further techniques to measure objects in photographs and digital images. By using the software, any object in the image can be measured diagonally, vertically, and horizontally. The device and its software enable the user to determine two-dimensional measurements within a photograph.

  5. An Experimental Study on Hysteresis Characteristics of a Pneumatic Braking System for a Multi-Axle Heavy Vehicle in Emergency Braking Situations

    2017-08-01

    Full Text Available This study aims to investigate the hysteresis characteristics of a pneumatic braking system for multi-axle heavy vehicles (MHVs. Hysteresis affects emergency braking performance severely. The fact that MHVs have a large size and complex structure leads to more nonlinear coupling property of the pneumatic braking system compared to normal two-axle vehicles. Thus, theoretical analysis and simulation are not enough when studying hysteresis. In this article, the hysteresis of a pneumatic brake system for an eight-axle vehicle in an emergency braking situation is studied based on a novel test bench. A servo drive device is applied to simulate the driver’s braking intensions normally expressed by opening or moving speed of the brake pedal. With a reasonable arrangement of sensors and the NI LabVIEW platform, both the delay time of eight loops and the response time of each subassembly in a single loop are detected in real time. The outcomes of the experiment show that the delay time of each loop gets longer with the increase of pedal opening, and a quadratic relationship exists between them. Based on this, the pressure transient in the system is fitted to a first-order plus time delay model. Besides, the response time of treadle valve and controlling pipeline accounts for more than 80% of the loop’s total delay time, indicating that these two subassemblies are the main contributors to the hysteresis effect.

    2015-10-01

    Family-centered rounds (FCR) has become a leading model for pediatric inpatient rounding. During FCR, faculty must balance trainees' educational needs with patient care priorities. Investigators have examined trainees' views on effective teaching during FCR, but none have evaluated what family members and nurses consider to be effective teaching behaviors of attending physicians. The authors sought to explore family members' and nurses' perspectives on effective teaching behaviors during FCR. The authors conducted (2012-2013) a qualitative study of families and nurses at an academic children's hospital where FCR is the standard model for inpatient rounds. Nurses and families familiar with FCR participated in separate focus groups. The authors reviewed focus group transcripts using techniques of qualitative content analysis; they generated codes and developed categories, supported by illustrative quotations. Fifteen nurses and 13 family members participated in the focus groups. The unifying theme was that situational awareness on behalf of the attending physician is essential for FCR to be educational for all participants. The authors identified four categories of awareness-(1) cognitive factors, (2) logistics and time management, (3) physical environment, (4) emotional state-and developed a set of effective teaching strategies based on participants' comments. The findings of this study support previous work identifying effective FCR teaching strategies, but this study is the first to include the perspectives of families and nurses. The inclusion of these participants provides a framework for faculty development and training to improve the educational value of FCR.

    One of the major advantages of store-based retail formats is the availability of products. The unavailability of products is a major threat for store-based retail formats as out of stock (OOS) situations are considered to be some of the most displeasing occurrences for consumers, resulting in dissatisfaction. As avoiding or recovering from OOS situations are matters of allocating limited resources (e.g. staff, money) wherever they are most effective, this work recommends actions that retailer...

    Full Text Available According to UNESCO, the number of ‘out-of-school’ children and youth in Thailand is the fifth in Asia and second in ASEAN. Currently, the accumulated number is about 1.7 million people. The purposes of this research are to study ‘out-of-school’ children and youth situations and method of education provided for them from the related organizations and networks. The results of this study reveal that the problems of the ‘out-of-school’ children and youth include low quality of life, lack of life skills and social skills, and behavior problems. The causes are poverty, low achievement in school, and behavior issues which cause dismissal from school. What needs to be provided for them from related organizations are a suitable system of education and vocational skills training. The activities provided by related organizations can be categorized as 1 life skills, social skills and self-esteem enhancement activities 2 funding and resources, which help to open up educational opportunities, and 3 the development of local mechanism to develop them in each area.

    Full Text Available Among the numerous studies dealing with the issue of family succession, the majority cities the succession process as a key issue in social reproduction and perpetuation of family farms. Thus, the study aimed to identify the actual situation among academics of UFFS Agronomy Course and their parents when the topic family succession is placed in focus. The methodology used was the application of a structured survey prepared in order to answer the doubts. The survey was designed in online way being sent an access link to the e-mail address previously, and then collected from every academic who had links with the countryside. For others, it was printed, delivered, and then collected. The data were analyzed using descriptive statistics. As a result was obtained that even though there are differences of opinion, the vast majority of young people show comfortable in become a farmer and to continue the current business of the parents. Over 83% of men and 92% of women in the parent class intend to hold family succession still alive, and the children respect this opinion giving autonomy to the parents to carry out the succession when they consider most appropriate.

    Officials are expected to perform impeccably despite the wide range of stressors they experience. A stressor that officials frequently report is situation criticality. Situation criticality is comprised of score differential (i.e., more pressure in close games) and time remaining in a game (i.e., more pressure as time expires), which affects athletes' stress levels. The present study explored the effect of situation criticality on officials' stress levels. High school basketball officials (n = 108) with an average of 18.1 (SD = 11.2) years of officiating experience were given a survey packet containing game situations that varied in criticality. For each game situation (n = 9) officials completed the overall stress and appraisal portions of the Stress Appraisal Measure (SAM). Results revealed that situation criticality has an effect on officials' perceived stress levels. Both threat and challenge appraisals were positively correlated with perceived stress. Overall, these findings indicate that officials' stress levels fluctuate within games depending on score differential and time of game. The findings encourage officials to recognise and manage their stress, possibly through their appraisals. Additionally, the findings can affect the training of officials in the management of stress, as well as prompt the consideration of potential rule changes that reflect the increased situational demands on officials in critical situations (e.g., expanded instant replay).

  11. Putting judging situations into situational judgment tests: evidence from intercultural multimedia SJTs.

    2015-03-01

    Although the term situational judgment test (SJT) implies judging situations, existing SJTs focus more on judging the effectiveness of different response options (i.e., response judgment) and less on how people perceive and interpret situations (i.e., situational judgment). We expand the traditional SJT paradigm and propose that adding explicit assessments of situational judgment to SJTs will provide incremental information beyond that provided by response judgment. We test this hypothesis across 4 studies using intercultural multimedia SJTs. Study 1 uses verbal protocol analysis to discover the situational judgments people make when responding to SJT items. Study 2 shows situational judgment predicts time-lagged, peer-rated task performance and interpersonal citizenship among undergraduate seniors over and above response judgment and other established predictors. Study 3 shows providing situational judgment did not affect the predictive validity of response judgment. Study 4 replicates Study 2 in a working adult sample. We discuss implications for SJT theory as well as the practical implications of putting judging situations back into SJTs. PsycINFO Database Record (c) 2015 APA, all rights reserved.

    Full Text Available In this paper we analyzed the cirumstances of every day life which requires the need to adapt the leadership style. Leadership needs a lot of abilities and skills, including the capability to communicate. The paper deals with leader’s need of changing the style of leading as organizational circumstances change. The process is efficient only when the leaders and the followers have the right climate. The importance of this process is reflected in the productivity of the organization. As the economic climate changes the leadership style needs to be changed and also the style of communication throughout the leader coaches, coordinates, evaluates and supervises. Leadership is about organizing a group of people to achieve a goal. The leader may or may not have any formal authority. Students of leadership have produced theories involving traits, situational interaction, function, behavior, power, vision and values, charisma, and intelligence, among others. This paper describes the styles of leadership which the leaders must use and switch when is needed in comparison with what leadership is about.

    Full Text Available Carsharing is becoming very popular in the western world as an effective method to contain rising prices of fuel and vehicles. It was brought about as a possible solution to the changing condition of growing economies and population where there is an increased need for travel but there is also a need for expense economizing. Due to its role in reducing fuel consumption, controlling pollution and traffic congestion, there is an increased usage of carsharing services as an alternative transportation option in big cities. Today, worldwide several different carsharing methods are being used. This paper examines the current situation of carsharing in the world and two initiatives for starting carsharing programs in Croatia. The main goal of this paper is to define what carsharing is, how successful it is in the world and if there is potential for it in Croatia. The most developed carsharing regions in the world are Western Europe and North America. In the last several years Asia, Australia and South America have started carsharing projects and have the biggest growth in members and vehicles. Carsharing is still not recognized in Croatia. There were a few initiatives for starting the program but they failed. In order to determine the possibility and potential of carsharing in Croatia it is necessary to conduct further market research.

    From the company that brought the world an integral heating and cooling food service system after originally developing it for NASA's Apollo Program, comes yet another orbital offshoot: a product that can be as thin as paper and as strong as steel. Nextel Ceramic Textiles and Composites from 3M Company offer space-age protection and innovative solutions for hot situations, ranging from NASA to NASCAR. With superior thermal protection, Nextel fabrics, tape, and sleevings outperform other high temperature textiles such as aramids, carbon, glass, and quartz, permitting engineers and manufacturers to handle applications up to 2,500 F (1,371 C). The stiffness and strength of Nextel Continuous Ceramic Fibers make them a great match for improving the rigidity of aluminum in metal matrix composites. Moreover, the fibers demonstrate low shrinkage at operating temperatures, which allow for the manufacturing of a dimensionally stable product. These novel fibers also offer excellent chemical resistance, low thermal conductivity, thermal shock resistance, low porosity, and unique electrical properties.

    The present study examined the influence of the individual use of media on attitudes towards nuclear power with focus in the run-time extension of German nuclear power plants, planned by the German government in the year 2010. The theoretical framework for explaining media effects on attitudes based on opinion research as well as on the second-level agenda setting. This approach assumes that highlighting attributes about attitude objects in the media makes them cognitively more accessible for recipients, so that these attributes are used to evaluate attitude object. In this study, arguments for and against the run-time extension were defined as attributes. For the investigation of individual media effects, this study was carried out in a two-method design to combine survey data and content analysis data on an individual level. From 16.08.2010 to 05.09.2010 the data on attitudes towards the planned run-time extension, nuclear power, energy, policy as well as individual media usage was collected in a representative telephone survey of n=551 people in Thuringia. In a quantitative content analysis the pro and contra arguments about the planned run-time extension in n=480 articles and news items, published during six months before the political decision, were analyzed. The findings of the content analysis showed that the media reported from 08.03.2010 to 05.09.2010 overall positively about the planned run-time extension and that the coverage intensity increased significantly shortly before the political decision. The main focus was on arguments regarding the efficiency and security of supply. By combining the content analysis data with the media usage data, new variables (sum and average value indices) for the specific individual media input of arguments about the run-time extension were formed. With these variables medium- and long-term media effects on attitudes towards nuclear power were tested. The results of the regression analyses showed that the individual media

    2010-11-01

    Disaster relief can be seen as a dynamic multi actor process with actors both joining and leaving the relief work during the help and rescue phase after the disaster has occurred. Actors may be governmental agencies, non profit voluntary organisations or spontaneous helpers comprised of individual citizens or temporal groups of citizens. Hence, they will vary widely in agility, competence, resources, and endurance. To prepare for for disasters a net based Agora with simulation of emergency situations for mutual preparation, training, and organisational learning is suggested. Such an Agora will ensure future security by: -Rising awareness and preparedness of potential disaster responders by help of the components and resources in the netAgora environment; -Improving cooperation and coordination between responders; -Improving competence and performance of organisations involved in security issues; -Bridging cultural differences between responders from different organizations and different backgrounds. The developed models are intended to reflect intelligent anticipatory systems for human operator anticipation of future consequences. As a way to catch what should be included in this netbased Agora and to join the split pictures that is present, Team Syntegrity could be a helpful tool. The purpose of Team Syntegrity is to stimulate collaboration and incite cross fertilization and creativity. The difference between syntegration and other group work is that the participants are evenly and uniquely distributed and will collectively have the means, the knowledge, the experience, the perspectives, and the expertise, to deal with the topic. In this paper the possibilities with using Team Syntegrity in preparation for the development of a netbased Agora is discussed. We have identified that Team Syntegrity could be useful in the steps User Integration, Designing the netAgora environment, developing Test Scenarios, and assessment of netAgora environment.

    The annual number of detainees held in police custody in France is approximately 700,000. Medical data regarding arrestees are scarce across countries. We present the medical characteristics of detainees kept in police custody, including addictive behaviours and high-risk medical situations. We conducted a prospective study over 1 year in a suburban area near Paris. A total of 19,098 medical examinations were performed on 13,317 individuals. The examinations mainly concerned male subjects (18,116 of 19,098, 95 %). Median age was 24 years (range 13-83). Medical examination was requested by the detainee in 6,638 of 16,801 cases (40 %). Assaults were reported in 4,052 of 17,312 cases (23 %) and occurred at the time of arrest in most cases (2,243, 13 %). A total of 2,394 of 13,317 detainees (18 %) had at least one chronic somatic disorder including asthma (603, 5 %), diabetes (263, 2 %) and arterial hypertension (205, 2 %). A history of psychiatric disorder was reported by 6 % of individuals (674 of 11,787). Regular alcohol drinking was reported by 58 % of detainees. Illicit drug use mainly involved cannabis (4,021 cases, 30 %). In 14,661 of 19,098 cases (77 %), detainees were considered to be unconditionally fit for detention in custody, and 274 detainees (1 %) were declared unfit to be detained. The present study showed a high frequency of alcohol or substance use and reported assaults or traumatic lesions in arrestees. Attending physicians should pay particular attention to addictive behaviours and traumatic injuries in arrestees, both for immediate care and for prevention.

    In high-rate experiments a situation can occur in which the data rate temporarily exceeds the available bandwidth. With self-triggered front end electronics such overload situations would lead, without further measures, to uncontrolled data losses and potentially large number of incomplete events. Mechanisms needed to control data losses and to ensure complete events can be understood using simulations performed by the hardware description language SystemC. Simulations of a simplified n-XYTER based front-end electronics are presented that give first insight in the behaviour of data flow and data losses in the DAQ system of the CBM experiment.

    Panic attacks (PAs) are common in many psychiatric disorders other than panic disorder, especially social anxiety disorder (SAD). PAs have been associated with increased severity, comorbidity, and impairment in many disorders; therefore, PAs can now be used as a descriptive specifier across all DSM-5 disorders. However, the clinical implications of PAs in SAD remain unclear. The aim of the present investigation was to examine demographic and clinical characteristics associated with SAD-related situational panic attacks in a large, representative epidemiological sample of individuals with SAD (N=1138). We compared individuals with SAD who did and did not endorse situational PAs in terms of demographic factors, fear/avoidance of social situations, distress, impairment, and diagnostic comorbidity. Being male, black, Asian, or over 65 years old was associated with a decreased likelihood of experiencing situational PAs, whereas being unemployed was associated with an increased likelihood. Individuals with situational PAs also exhibited greater fear and avoidance of social situations, impairment, coping-oriented substance use, treatment utilization, and concurrent and longitudinal psychiatric comorbidity. Consistent with most epidemiologic studies, the information collected relied on self-report, and not all participants were available for both waves of assessment. The present findings suggest that SAD-related situational PAs are associated with more severe and complex presentations of SAD. Implications for the assessment and treatment of SAD, as well as for the use of PAs as a descriptive specifier for SAD, are discussed. Copyright © 2014 Elsevier B.V. All rights reserved.

    The present work demonstrates a method for constructing theoretically based situational classifications and exploring their behavioral implications. Fundamental motives theory (FMT; Kenrick, Griskevicius, Neuberg, & Schaller, 2010; Kenrick, Neuberg, Griskevicius, Becker, & Schaller, 2010) proposes that humans have evolved seven specific social motives that would be differentially evoked by different situations. Experts in FMT used the Riverside Situational Q-sort (RSQ) to describe prototypic motive-relevant situations and the Riverside Behavioral Q-sort (RBQ) to construct templates representing predictions of how people would behave in them. A sample of 201 undergraduate participants used the RSQ to describe situations they had experienced within the past 24 hours, and they described their behavior in each situation using the RBQ. For both the RSQ and RBQ, self-protection and disease avoidance templates were highly similar to each other and different from mate-seeking and affiliation templates. Participants more often reported experiencing situations similar to the mate-seeking, affiliation, and kin care templates and less often reported experiencing situations similar to the self-protection and disease avoidance templates. Participants' reported behavior was consistent with expectations from FMT. This study illustrates how relations between situations and behavior can be illuminated through the use of theoretically derived templates. © 2014 Wiley Periodicals, Inc.

    Full Text Available Background: Emotional context may play a crucial role in movement production. According to simulation theories, emotional states affect motor systems. The aim of this study was to compare postural responses assessed by posturography and electromyography when subjects were instructed to imagine themselves in a painful or a non-painful situation.Methods: Twenty-nine subjects (22.3 ± 3.7 years participated in this study. While standing quietly on a posturographic platform, they were instructed to imagine themselves in a painful or non-painful situation. Displacement of the centre of pressure (COP, leg muscle electromyographic activity, heart rate, and electrodermal activity were assessed in response to painful and non-painful situations.Results:The anteroposterior path was shorter (p<0.05 when subjects imagined themselves in a painful situation (M = 148.0 ± 33.4 mm compared to a non-painful situation (158.2 ± 38.7 mm. Higher Tibialis Anterior (TA activity (RMS-TA = 3.38 ± 1.95 % vs 3.24 ± 1.85 %; p < 0.001 and higher variability of Soleus (SO activity (variation coefficient of RMS-SO = 13.5 ± 16.2 % vs M = 9.0% ± 7.2 %; p<0.05 were also observed in painful compared to non-painful situations. No significant changes were observed for other physiological data Conclusion: This study demonstrates that simulation of painful situations induces changes in postural control and leg muscle activation compared to non-painful situations, as increased stiffness was demonstrated in response to aversive pictures in accordance with previous results.

    Full Text Available The transgenic foods had appeared as result of the scientific and technological advances of genetic engineering applied to agriculture, configuring themselves in a current quarrel and sufficient controversy, about how much the benefits and curses brought to the consumers and the proper environment. In this intention, this study has as objective to verify the level of knowledge of customers of a supermarket of the noble area of the city of Fortaleza, on the thematic of the transgenic. Questionnaires structuralized with questions on transgenic foods with consumers of a situated supermarket in noble area of the city of Fortaleza in the period of March of 2003 had been applied. Sixty consumers had participated of the study who at the moment were making purchases in the supermarket. It was presented the end of the interview, to each consumer, a list of products, removed of the guide of the transgenic food consumer and not transgenic, available on the Greenpeace. In each list, people would have to recognize or not products of its habitual consumption. It was verified that 50% of the interviewed people had higher level of school knowledge, with 63,3% answering that they knew what transgenic foods are; 53,3% always look at the label during the purchase, being that the majority (76,7% never saw, in the label, mention if the product is or not transgenic. It was evidenced, when interrogating on the possible risks to the health, that 33.3% find that they cause illnesses, however 51.7% would not be imported in consuming them. The opinion of the people regarding the release of these products is major (73,3% in agreeing that the Federal Government must wait more research. From the list of products presented to the interviewed, 60% had told that they consume enter 5 to 9 products. It was evidenced that still a lack knowledge exists on the presence of transgenic in industrialized products, as well as how much to the risks consuming it. It has necessity of

    For children with low self-regulation in the preschool years, the likelihood of poorer intellectual, health, wealth and anti-social outcomes in adulthood is overwhelming. Yet this knowledge has not yielded a framework for understanding self-regulatory change, nor generated particularly successful methods for enacting this change. Reconciling insights from cross-disciplinary theory, research and practice, this study seeks to implement a newly developed program of low-cost and routine practices and activities for supporting early self-regulatory development within preschool contexts and to evaluate its effect on children's self-regulation, executive function and school readiness; and educator perceived knowledge, attitudes and self-efficacy related to self-regulation. The Early Start to Self-Regulation study is a cluster randomized, controlled trial for evaluating benefits of the Preschool Situational Self-Regulation Toolkit (PRSIST) program, when implemented by early childhood educators, compared with routine practice. The PRSIST program combines professional learning, adult practices, child activities and connections to the home to support children's self-regulation development. Fifty preschool centers in New South Wales, Australia, will be selected to ensure a range of characteristics, namely: National Quality Standards (NQS) ratings, geographic location and socioeconomic status. After collection of baseline child and educator data, participating centers will then be randomly allocated to one of two groups, stratified by NQS rating: (1) an intervention group (25 centers) that will implement the PRSIST program; or (2) a control group (25 centers) that will continue to engage in practice as usual. Primary outcomes at the child level will be two measures of self-regulation: Head-Toes-Knees-Shoulders task and the PRSIST observational assessment. Secondary outcomes at the child level will be adult-reported measures of child self-regulation, executive function and

    2007-01-01

    In high-risk environments such as air traffic control, leadership on different levels plays a certain role in establishing, promoting, and maintaining a good safety culture. The current study aimed to investigate how leadership styles, leadership style adaptability, and over and under task leadership behavior differed across situations, operative conditions, leadership structures, and working tasks in an air traffic control setting. Study locations were two air traffic control centers in Sweden with different operational conditions and leadership structures, and an administrative air traffic management unit. Leadership was measured with a questionnaire based on Leader Effectiveness and Adaptability Description (LEAD; Blanchard, Zigarmi & Zigarmi, 2003; Hersey & Blanchard, 1988). The results showed that the situation had strong impact on the leadership in which the leadership behavior was more relationship oriented in Success and Group situations than in Hardship and Individual situations. The leadership adaptability was further superior in Success and Individual situations compared with Hardship and Group situations. Operational conditions, leadership structures and working tasks were, on the other hand, not associated with leadership behavior.

    Most often postural control is evaluated in posturography, i. e. in a static testing condition. The aim of this study was to evaluate correlations and differences between posturography and dynamic testing situations to get information about the informative value of static testing situations on dynamic conditions. 40 healthy subjects participated in this study (m=23; w=17; age: 23.8±2.9 years; height: 177.0±8.5 cm; weight: 71.5±10.5 kg). Subjects were tested on their ability to maintain postural stability on a force platform (posturography, static condition) and on a movable and instable plate (dynamic condition). Furthermore, we analyzed balance correcting responses to a standardised disturbance of postural stability. EMG-activity was recorded of the following muscles: m. tibialis anterior, m. gastrocnemius lateralis, m. vastus lateralis, m. biceps femoris, and m. erector spinae. Pearson's Correlations were used to examine the relationship between postural control in static and in dynamic testing situations. Student's t-tests were used to examine differences in several parameters between static and dynamic testing situations. Comparisons of postural control in static and in dynamic conditions lead to marginal correlations between performances in these test situations (r=-0.02 to r=0.45). Moreover, EMGactivity showed changes concerning quantitative parameters and coordination patterns. Regarding correlations and analyses of EMG-activity we hypothesised different postural control strategies depending on each testing situation. Therefore, postural control seems not to be a generalizable ability. These data suggest that there is doubt on the use of posturography in static condition to predict performance in dynamic situations that could induce falls in elderly people or injuries in athletes. It appears comprehensible that dynamic testing situations are more suitable.

  19. Situating forensic traces in time.

    2012-06-01

    Situating events and traces in time is an essential problem in investigations. To date, among the typical questions issued in forensic science, time has generally been unexplored. The reason for this can be traced to the complexity of the overall problem, addressed by several scientists in very limited projects usually stimulated by a specific case. Considering that such issues are recurrent and transcending the treatment of each trace separately, the formalisation of a framework to address dating issues in criminal investigation is undeniably needed. Through an iterative process consisting of extracting recurrent aspects discovered from the study of problems encountered by practitioners and reported in the literature, common mechanisms were extracted and provide understanding of underlying factors encountered in forensic practise. Three complementary approaches are thus highlighted and described to formalise a preliminary framework that can be applied for the dating of traces, objects, persons and indirectly events.

For this reason, ESO has until now been silent in these matters, but we have now become obliged to make our opinion known". The ESO representative also made it clear, that "ESO does not question the rights of the claimants to recur to the Chilean Tribunals which must decide on the matter of ownership, and that ESO cannot be party to this lawsuit". He added that "ESO fully trusts that the Chilean Government will do whatever is necessary to defend the immunity of ESO". THE CURRENT SITUATION During the past few days, declarations from high officials at the Chilean Ministry of Foreign Affairs have been made which clearly confirm ESO's immunity of jurisdiction from Chilean Courts. The same opinion has been ventured by Chilean experts in international law, quoted in various Chilean newspapers. On Friday, February 17, the Chilean Minister of Foreign Affairs, Mr. Jose M. Insulza, made a similar, very eloquent statement. ESO welcomes these articulate expressions that support its official position and trusts that the current situation will be speedily resolved by the competent Chilean authorities, so that the construction work at Paranal will not be stopped. During the past three decades, ESO's presence in Chile has been characterised by good relations to all sides. The development of astronomy in Chile during the past decades has reached such a level that it will now benefit from a new quality of cooperation. In addition to its past and numerous services to Chilean astronomy, ESO has recently considered to establish a "guaranteed" observing time for astronomers from this country, both at La Silla and the future VLT observatory on Paranal. With a proposed 10 percent quota for the VLT, Chilean astronomers will in fact have free access to the equivalent of 40 percent of one 8.2-metre telescope; the associated, not insignificant cost is entirely carried by ESO. ESO has also considered to incorporate

    Full Text Available After a breakdown in employment relations in the maintenance section of a higher education institution, the authors were asked to intervene in order to try and solve the employment relations conflict situation. It was decided to employ the Nominal Group Technique (NGT as a tool in problem identification during conflict in the workplace. An initial investigation of documentation and interviews with prominent individuals in the organisation was carried out. The NGT was then used in four focus group discussions to determine the important issues as seen by staff members. The NGT facilitates the determination of shared perceptions and the ranking of ideas. The NGT was used in diverse groups, necessitating adaptations to the technique. The perceived causes of the conflict were established. The NGT can be used in a conflict situation in the workplace in order to establish the perceived causes of employment relations conflict.

    Distinctions have been made between the two main forms of intimate partner violence: intimate terrorism (IT) and situational couple violence (SCV), depending on whether the violence is part of a general pattern of control. Differential effects also exist between IT and SCV. However, the IT/SCV distinction and their differential effects have yet to be demonstrated in violent intimate relationships in China. We aimed to identify IT and SCV among Chinese women who reported partner violence in Hong Kong and to differentiate the effects of IT and SCV on their mental health outcomes. A mixed-method design was used in a cross-sectional study to collect quantitative and qualitative data from women 18 years of age or older who had been victims of intimate partner violence in the past year. Six hundred and thirteen women were recruited from 18 districts in Hong Kong. Quantitative instruments were administered to assess intimate partner violence, control by an intimate partner, and mental health outcomes. Individual face-to-face interviews were conducted with 200 of the women to capture their experiences of intimate partner violence and the context in which it occurred. Of the 613 women, 215 (35.1%) were identified as victims of IT and 324 (52.9%) as victims of SCV. Compared to SCV victims, IT victims reported significantly more violence-related physical injury (p depression (p < 0.001) and posttraumatic stress disorder (p < 0.001). The interviews revealed two broadly different pictures with IT victims describing their relationship problems as serious and life-threatening, and physical violence was part of the controlling behaviors used by their partners. Such details were not reported by those in the SCV group. Our findings indicate that violence in intimate relationships in China is not a unitary phenomenon, and it has at least two forms, IT and SCV, which were shown to have differential effects on Chinese women. The findings regarding the IT/SCV distinction and their

    Full Text Available Over 20 million Tweets were used to study the psychological characteristics of real-world situations over the course of two weeks. Models for automatically and accurately scoring individual Tweets on the DIAMONDS dimensions of situations were developed. Stable daily and weekly fluctuations in the situations that people experience were identified. Predicted temporal trends were found, providing validation for this new method of situation assessment. On weekdays, Duty peaks in the midmorning and declines steadily thereafter while Sociality peeks in the evening. Negativity is highest during the workweek and lowest on the weekends. pOsitivity shows the opposite pattern. Additionally, gender and locational differences in the situations shared on Twitter are explored. Females share both more emotionally charged (pOsitive and Negative situations, while no differences were found in the amount of Duty experienced by males and females. Differences in the situations shared from Rural and Urban areas were not found. Future applications of assessing situations using social media are discussed.

    Conditioning is often thought of as a basic, automatic learning process that has limited applicability to higher-level human behavior. In addition, conditioning is seen as separable from, and even secondary to, "innate" processes. These ideas involve some misconceptions. The aim of this article is to provide a clearer, more refined sense of human sexual conditioning. After providing some background information and reviewing what is known from laboratory conditioning studies, human sexual conditioning is compared to sexual conditioning in nonhumans, to "innate" sexual responding, and to other types of human learning processes. Recommendations for moving forward in human sexual conditioning research are included.

The risk of grave accident is so limited to a very low level of probability. He cannot be however completely pushed aside. The expression ' radiological emergency situation ' indicates a situation which ensues from an incident or of an accident risking to lead to an emission of radioactive materials or a level of radioactivity susceptible to strike a blow at the public health. The term ' nuclear crisis ' is used for the events which can lead to a radiological emergency situation on a nuclear basic installation or during a transport of radioactive materials.

    Networking of power plant computer systems is becoming increasingly common. Furthermore, instrumentation and control systems are being connected with general power plant networks to make process information available to administrative personnel. This increases the risk of accidental or intentional access from outside the system (e.g. by hackers). Firewall systems are used to prevent such outside access. A firewall is the sole gateway between two networks which are to be kept separate, and is used to filter and control access to the protected network. Cryptography and personal chip cards are also used to provide additional protection. (orig.) [Deutsch] Rechnersysteme im Kraftwerk werden heute mehr und mehr vernetzt.

    2009-09-01

    Stalking is often viewed as a precursor to violence, but determining which stalkers might attack is a difficult task. This study overcomes shortfalls in previous investigations by adopting a pseudo-prospective design and examining potential risk factors for different types of stalker. Demographic, behavioural and diagnostic information was collected from stalkers referred to a community forensic mental health service (n=211). Potential risk factors for stalking violence were identified using odds ratios and chi2 tests, and entered into logistic regression models. Model utility was assessed using receiver operating characteristic curves. Amongst Rejected ex-intimate stalkers, violence was best predicted by previous violence, making threats and being employed (area under the curve=0.75), while for stalkers with other motives and relationships to the victim, being aged less than 30 years, substance use at the time of stalking and prior violence best predicted stalking violence (area under the curve=0.80). Stalkers at increased risk of violence can be accurately identified by examining motivational and relationship type in conjunction with specific relevant risk factors. Previous violence is a particularly important risk factor, as are threats amongst ex-intimate stalkers. Approach behaviours and psychosis were shown to be less useful in predicting violence.

    The purpose of the present evaluation was to use SIR-C and X-SAR data for forest surveying and assess their suitability for this task. Amongst other work this included the discrimination of forest and non-forest, demarcation of cleared areas within forests, discrimination of different forest types, and assessment of the influence of foliation. The chief steps of the study were the preparation of radar data, accompanying aerial photo evaluation for the extraction of training and verification areas, and detailed signature analysis. Evaluation trials in ``Oberpfaffenhofen`` supertest area yielded unsatisfactory results when it came to discriminating different forest ecosystems. This can be attributed to the very heterogeneous and small-scale structure of the area and the absence of topographically coded X, C, and L band data. In the second study area, located in the ``Bavarian Forest National Park``, geocoded data of all three bands were available in the form of combined products. This permitted using the mask of the local angles of incidence to reduce the influence of relief. In this case distinguishability within wooded regions was also enhanced. A general finding was that ground resolution as it presents to the user is clearly poorer than the nominal resolution. What impressed us most was the high degree of weather-independence of the radar data. All data handled in this study were recorded under conditions that would have made photography impossible.

    Full Text Available The paper reports a qualitative analysis of literacy situations generated by a family literacy program- that took place in the homes of children from poor urban population of Argentina. The analysis is centred in adult interventions during activities focused in different abilities required to use the writing system -sound games and writing activities. Results showed that the activities adopt an asymmetric format similar to the sequence initiation-response-feedback observed in the classroom. It was also observed that adults frequently autorepair the directives and questions they make to the children. In the writing activities adults and older children model, dictate the name of the letters and help the little children to analyse the sounds of the words. The children have the opportunity to recognize and write letters, pay attention to the sounds of the words and establish phoneme-grapheme correspondences.

  1. The political suspension of ethics: proposals for a historical study of reversal of values in a situation of martial conflict in Lanka

    Directory of Open Access Journals (Sweden)

    Peter Schalk

    2006-01-01

    Full Text Available The overall aim of this project is to focus on the general socio-economic and political conditions leading to martial conflict in relation to religious and secular values, value systems and ideologies in Īlam/Lankā, with special regard to their transformation. It deals with the extent of reversal and re-reversal in the course of the conflict and reconciliation respectively. These values are reversed through political decisions in a martial situation. It is true that martial conflicts arise over the distribution of resources and territory and not over theological issues. When, however, religion is placed in a martial context and related to the interests of one group, then even a sophisticated theology can take the form of an identity-bestowing ideology and adopt martial doctrines such as the concept of just war. Territorial and social definitions of citizenship are replaced by definitions relating to sacred boundaries. Christianity may turn into German Christianity or Serbian Christianity, Hinduism into Hindūtva and Buddhism into Sinhalatva. The overall martial context is finally symbolised in religion as an identity marker alongside sacralisation of language, history, and territory, etc. This martial context generates a religious surplus even within secular ideologies and leads both to a suspension and a reversal of values in established religions. The proponents are ideologues, including monks and priests, and politicians in the widest sense. They become warmongers in a martial situation, where they become ‘authentic’ and authoritative. In a non-war situation they are marginalised as extremists. During war, they suspend fundamental human values, but they ‘suspend’ in the specifically German (Hegelian sense of aufheben, meaning to elevate, to save and to call off. They do not annihilate these values, only to recall and retrieve them during truces and cease-fires, in situations of non-war, and diplomatic or ecumenical encounters, or

    The validity of the concept of situational (i.e. reactive) depression as distinct from other major depressive subtypes is examined in terms of psychosocial stressors, personality features, current symptomatology, and clinical course and follow-up. Thirty-eight patients with a recent onset of situational major depressive disorder (i.e. the disorder developed after an event or in a situation the diagnostician deemed likely to have contributed to the episode at that time) were compared with 68 non-situational major depressive patients. These patients were participants in the clinical studies of the NIMH-Clinical Research Branch Collaborative Program on the Psychobiology of Depression. No significant differences between the two groups were found in the total number, content areas, or other categorizations of life events, experienced prior to onset. Some statistically significant differences in current symptomatology and in clinical course and follow-up measures were obtained, but there were none in personality traits. Implications of these results in relation to previously published reports are discussed and caution is recommended in the use of the term situational depression until more definitive data become available.

    Research on language comprehension suggests a strong relationship between working memory span measures and language comprehension. However, there is also evidence that this relationship weakens at higher levels of comprehension, such as the situation model level. The current study explored this relationship by comparing 10 grapheme-color synesthetes who have additional color experiences when they read words that begin with different letters and 48 normal controls on a number of tests of complex working memory capacity and processing at the situation model level. On all tests of working memory capacity, the synesthetes outperformed the controls. Importantly, there was no carryover benefit for the synesthetes for processing at the situation model level. This reinforces the idea that although some aspects of language comprehension are related to working memory span scores, this applies less directly to situation model levels. This suggests that theories of working memory must take into account this limitation, and the working memory processes that are involved in situation model construction and processing must be derived.

    The aim of the project was to provide a basis for the revision of the so-called 'Efficiency Path' of the Swiss Association of Engineers and Architects (SIA) in the context of the goals of the 2000-Watt-Society. Particularly, the objective is to find the conditions in which the specific goals of the 2000-Watt-Society for residential, school and office buildings could be reached. Considered indicators are the per capita primary energy use in terms of average power and the greenhouse gas emissions. A bottom-up model was developed to estimate final and primary energy demand of the mentioned building types, broken down by different types of energy utilisation. Assumptions were made regarding the most important physical drivers as well as for regarding energy efficiency parameters of new buildings, building retrofits, building technologies and other energy applications in the residential, school and office buildings. Two basic scenarios were developed: an ambitious efficiency scenario was compared to a reference scenario which included current and foreseeable energy policy elements. Regarding electricity supply three scenario-variants of the so-called Swiss Energy Perspectives of the Swiss Federal Office of Energy (SFOE) were used: variant I b 'business-as-usual - nuclear and central fossil plants', IV a: Path to the 2000-Watt-Society - nuclear' and, IV e 'Path to the 2000-Watt-Society - renewable energies'. With this respect it was found that in the case of the efficiency scenario the influence of the electricity generation mix is relatively small. This finding is explained by the fact that hydro power (which is held more or less at the current level) has a large share in the power supply mix in the case of the efficiency scenario with moderate electricity demand and that hydro power is efficient in terms of primary energy and has considerably low greenhouse gas emissions. The results of the study show that with the underlying

  5. Exploring and Expanding the Category of ‘Young Workers’ According to Situated Ways of Doing Risk and Safety—a Case Study in the Retail Industry

    2013-09-01

    Full Text Available Young adult workers aged 18–24 years have the highest risk of accidents at work. Following the work of Bourdieu and Tannock, we demonstrate that young adult workers are a highly differentiated group. Accordingly, safety prevention among young adult workers needs to be nuanced in ways that take into consideration the different positions and conditions under which young adult workers are employed. Based on single and group interviews with 26 young adult workers from six various sized supermarkets, we categorize young adult retail workers into the following five distinct groups: ‘Skilled workers,’ ‘Apprentices,’ ‘Sabbatical year workers,’ ‘Student workers,’ and ‘School dropouts.’ We argue that exposure to accidental risk is not equally distributed among them and offer an insight into the narratives of young adult workers on the subject of risk situations at work. The categorizations are explored and expanded according to the situated ways of ‘doing’ risk and safety in the working practices of the adult workers. We suggest that the understanding of ‘young’ as an age-related biological category might explain why approaches to prevent accidents among young employees first and foremost include individual factors like advice, information, and supervision and to a lesser degree the structural and cultural environment wherein they are embedded. We conclude that age cannot stand alone as the only factor in safety prevention directed at workers aged 18–24 years; if we do so, there is a risk of overemphasizing age-related individual characteristics such as awareness and cognitive limitations before structural, relational, and hierarchical dimensions at the workplace.

    Quitzau, Maj-Britt; Petersen, Jens-Phillip

    This paper illustrates how strategic and situated forms of knowledge may increase capacity to implement energy strategies in local urban development projects. Through analysis of front runner implementation projects, we show that the involved planners utilize situational learning processes...... strategically to develop more viable implementation trajectories. These findings resonate well with relational and network orienteered research in contemporary planning theory. In the selected case studies, we can see that planners deliberately seek to extend traditional planning approaches, like e.......g. regulation, with broader context‐specific learning processes. In doing so, we argue that – what we call – an implementation synergy is established by interlacing different forms of situational knowledge with strategic knowledge about how to reach a desired energy target. In conclusion, the paper identifies...

    Dementia impairs spatial orientation and route planning, thus often affecting the patient's ability to move outdoors and maintain social activities. Situation-aware deliberative assistive technology devices (ATD) can substitute impaired cognitive function in order to maintain one's level of social activity. To build such a system, one needs domain knowledge about the patient's situation and needs. We call this collection of knowledge situation model. To construct a situation model for the outdoor mobility of people with dementia (PwD). The model serves two purposes: 1) as a knowledge base from which to build an ATD describing the mobility of PwD; and 2) as a codebook for the annotation of the recorded behavior. We perform systematic knowledge elicitation to obtain the relevant knowledge. The OBO Edit tool is used for implementing and validating the situation model. The model is evaluated by using it as a codebook for annotating the behavior of PwD during a mobility study and interrater agreement is computed. In addition, clinical experts perform manual evaluation and curation of the model. The situation model consists of 101 concepts with 11 relation types between them. The results from the annotation showed substantial overlapping between two annotators (Cohen's kappa of 0.61). The situation model is a first attempt to systematically collect and organize information related to the outdoor mobility of PwD for the purposes of situation-aware assistance. The model is the base for building an ATD able to provide situation-aware assistance and to potentially improve the quality of life of PwD.

  8. The Bonding Situation in Metalated Ylides.

    2017-03-28

    Quantum chemical calculations have been carried out to study the electronic structure of metalated ylides particularly in comparison to their neutral analogues, the bisylides. A series of compounds of the general composition Ph3 P-C-L with L being either a neutral or an anionic ligand were analyzed and the impact of the nature of the substituent L and the total charge on the electronics and bonding situation was studied. The charge at the carbon atom as well as the dissociation energies, bond lengths, and Wiberg bond indices strongly depend on the nature of L. Here, not only the charge of the ligand but also the position of the charge within the ligand backbone plays an important role. Independent of the substitution pattern, the NBO analysis reveals the preference of unsymmetrical bonding situations (P=C-L or P-C=L) for almost all compounds. However, Lewis structures with two lone-pair orbitals at the central carbon atom are equally valid for the description of the bonding situation. This is confirmed by the pronounced lone-pair character of the frontier orbitals. Energy decomposition analysis mostly reveals the preference of several bonding situations, mostly with dative and ylidic electron-sharing bonds (e.g., P→C- -L). In general, the anionic systems show a higher preference of the ylidic bonding situations compared to the neutral analogues. However, in most of the cases different resonance structures have to be considered for the description of the "real" bonding situation. © 2017 The Authors. Published by Wiley-VCH Verlag GmbH & Co.

    In this study, input variables for chemical transport models were compared from different meteorological drivers each with other and with the measured friction velocities in one place. Friction velocities are used as a measure of the mechanical turbulence, but are made available neither by numerical weather models nor routinely available observations: so they must either recalculate or estimated. In this study, friction velocities (u{sup *}), which is measured for years by the DWD in Lindenberg near Berlin, averaged over 30 minutes and have been made available to FU Berlin, compared with modeled values. The considered models are firstly the diagnostic interpolation model TRAMPER, on the other the prognostic models of the DWD COSMO-EU and the EZMWF. The boundary layer relevant parameters from the NWM were recalculated from the involved groups, which has been made for the COSMO-EU the one from the FU Berlin, the other from IfT in Leipzig.

    2008-11-01

    The concept of situation has a long and venerable history in social psychology. The author argues that recent approaches to the concept of situation have confused certain important elements. Herein, the author proposes that attention to three of these elements will reinvigorate the concept of situation in social psychology: (a) that the analysis of situations should begin with their objective features; (b) that situations should be conceptualized as affordances; and (c) that the interpersonal core of situations, in particular the extent to which they are influenced by relationships, is the proper and most profitable focus for social psychology. These elements are consistent with recent developments in the study of situated social cognition and may help better define social psychology's position within the sciences.

    Community N-mixture abundance models for replicated counts provide a powerful and novel framework for drawing inferences related to species abundance within communities subject to imperfect detection. To assess the performance of these models, and to compare them to related community occupancy models in situations with marginal information, we used simulation to examine the effects of mean abundance (λ¯: 0.1, 0.5, 1, 5), detection probability (p¯: 0.1, 0.2, 0.5), and number of sampling sites (n site : 10, 20, 40) and visits (n visit : 2, 3, 4) on the bias and precision of species-level parameters (mean abundance and covariate effect) and a community-level parameter (species richness). Bias and imprecision of estimates decreased when any of the four variables (λ¯, p¯, n site , n visit ) increased. Detection probability p¯ was most important for the estimates of mean abundance, while λ¯ was most influential for covariate effect and species richness estimates. For all parameters, increasing n site was more beneficial than increasing n visit . Minimal conditions for obtaining adequate performance of community abundance models were n site  ≥ 20, p¯ ≥ 0.2, and λ¯ ≥ 0.5. At lower abundance, the performance of community abundance and community occupancy models as species richness estimators were comparable. We then used additive partitioning analysis to reveal that raw species counts can overestimate β diversity both of species richness and the Shannon index, while community abundance models yielded better estimates. Community N-mixture abundance models thus have great potential for use with community ecology or conservation applications provided that replicated counts are available.

    This study compared pilot situation awareness across three traffic management concepts. The Concepts varied in terms of the allocation of traffic avoidance responsibility between the pilot on the flight deck, the air traffic controllers, and a conflict resolution automation system. In Concept 1, the flight deck was equipped with conflict resolution tools that enable them to fully handle the responsibility of weather avoidance and maintaining separation between ownship and surrounding traffic. In Concept 2, pilots were not responsible for traffic separation, but were provided tools for weather and traffic avoidance. In Concept 3, flight deck tools allowed pilots to deviate for weather, but conflict detection tools were disabled. In this concept pilots were dependent on ground based automation for conflict detection and resolution. Situation awareness of the pilots was measured using online probes. Results showed that individual situation awareness was highest in Concept 1, where the pilots were most engaged, and lowest in Concept 3, where automation was heavily used. These findings suggest that for conflict resolution tasks, situation awareness is improved when pilots remain in the decision-making loop.

    Full Text Available The aim of the present study was to extend the existing findings on environmental flow precursors by adopting the DIAMONDS taxonomy of psychologically meaningful situation characteristics as a comprehensive theoretical framework. It was hypothesized that an individual's perception of the flow-related situation, particularly the dimensions of duty, intellect and positivity, would represent a more powerful predictor of the intensity of flow as compared to his or her basic personality traits. The first sample consisted of 169 employees who had to focus on the most engaging work-related event they had experienced in the past three months. They rated the characteristics of that situation and estimated the intensity of their flow experience. The second sample consisted of 96 students who participated in a challenging group activity. After the activity, they filled-in the same questionnaires as the first sample. Participants from both samples also rated their basic personality traits. Despite differences in the settings and flow-related situations evaluated, the obtained findings were similar for the two samples studied. While the association between flow and personality was weak, the situation characteristics were more strongly related to flow. Although the two samples differed with respect to the mean levels of the flow-related situation characteristics, regression analyses yielded similar results, suggesting that the intensity of flow at work and in studying is most prominently determined by situation characteristics related to intellect and positivity. Stable personality characteristics, on the other hand, had low predictive power in explaining the intensity of flow.

    The primary aim of this study was to identify coping strategies used to manage problematic tinnitus situations. A secondary aim was to determine whether different approaches were related to the level of tinnitus distress, anxiety, depression, and insomnia experienced. A cross-sectional survey design was implemented. The study sample was adults interested in undertaking an Internet-based intervention for tinnitus. Self-reported measures assessed the level of tinnitus distress, depression, anxiety, and insomnia. An open-ended question was used to obtain information about how problematic tinnitus situations were dealt with. Responses were investigated using qualitative content analysis to identify problematic situations. Further data analysis comprised of both qualitative and quantitative methods. There were 240 participants (137 males, 103 females), with an average age of 48.16 years (SD: 22.70). Qualitative content analysis identified eight problematic tinnitus situations. Participants had either habituated to their tinnitus (7.9%), used active (63.3%), or passive (28.8%) coping styles to manage these situations. Those who had habituated to tinnitus or used active coping strategies had lower levels of tinnitus distress, anxiety, and depression. The main problematic tinnitus situations for this cohort were identified. Both active and passive coping styles were applied to approach these situations. The coping strategies used most frequently and utilised in the widest range of problematic situations were using sound enrichment and diverting attention. Implications for Rehabilitation The main problematic tinnitus situations for this group of participants were identified. Overall, a limited range of strategies were used to deal with individual problematic situations. The use of sound enrichment and diverting attention was applied in the widest range of problematic situations. The use of both active and passive coping styles was evident to approach these situations. The

    Practicing technical communicators deal with culture as an integral part of language and communication practices. Yet, etic models of culture based on dimensions of culture related to values (i.e. Hofstede, Trompenaars, Edward T. Hall, Kluckhohn & Strodtbeck) are so abstract that they are difficult......, the cultural dimension of power distance from Hofstede helps technical communicators approach the notion of context, but cannot be directly operationalized in design decisions for translating a product manual.

    The theory of situated learning claims that every idea and human action is a generalization, adapted to the ongoing environment, because what people see and what they do arise together. From this perspective, thinking is a physical skill. As we create names for things, shuffle around sentences in a paragraph, and interpret what our statements mean, every step is controlled not by reinstantiated grammars and previously constructed plans, but adaptively recoordinated from previous ways of seein...

    Two individuals are involved in a conflict situation in which preferences are ex ante uncertain. While they eventually learn their own preferences, they have to pay a small cost if they want to learn their opponent's preferences. We show that, for sufficiently small positive costs of information acquisition, in any Bayesian Nash equilibrium of the resulting game of incomplete information the probability of getting informed about the opponent's preferences is bounded away from zero and one.

    The informal caregivers perceive lack of choice to take on the role of caregiving, receiving little or no preparation for the caregiving role at home. The typical informal caregiver is female, either a spouse or adult child of the care recipient, and seldom shares the responsibilities of caregiving with other family members. The spouses worry about the ill relative, but also about what consequences the disease might have for their own life. The worries seem to vary with gender and disease. There are, to our knowledge, few previous longitudinal studies that have focused on gender differences among spouses of stroke patients. To explore gender differences among spouses in perceived psychological well-being and general life situation, during the first year after the patients' stroke event. Longitudinal study with three assessments regarding psychological well-being and general life situation during 1 year. The study took place at a stroke ward, Stockholm, Sweden. Consecutively 80 female and 20 male spouses of stroke patients admitted to a stroke unit participated. Data were analysed using analyses of variance. Female spouses have a negative impact on psychological well-being, while male spouses have a lower occurrence of emotional contacts in their social network. Consistently, the female spouses reported lower quality of life and well-being than the male spouses. This study generates the hypotheses that there are gender differences among spousal caregivers of stroke patients; female spouses are more negatively affected in their life situation due to the patients' stroke event than the male spouses. It is important to take the individual differences under consideration when designing a nursing intervention, to meet the different needs and demands of male and female caregivers. The interventions should focus on individual support, so that the caregivers can adapt to their new role and be comfortable and effective as informal caregivers.

  1. Non-problematic Situations in Social Workers’ and GPs’ Practice

    2016-10-01

    Full Text Available This study aims to describe and analyze written accounts of non-problematic situations by 28 social workers and 24 general practitioners (GPs. The results show that non-problematic situations were connected to professionals’ control of the intervention process. Non-problematic situations were described by social workers as situations where they had control of the relationship with the client either by the use of coercive means or by the client’s active cooperation. GPs referred to non-problematic situations as situations where they had control of the intervention process mainly by the use of professional knowledge. One main conclusion is that the ability to control the intervention process through control of the relationship with the client may be of significance to those professions where a central part of the professional jurisdiction involves changing clients’ behaviors. This conclusion means that professional knowledge is not the only way to control the professional intervention process.

In this population-based controlled study we compare short-term ( Methods Among 9,089 individuals aged 60-69 who participated in HUNT-2, 334 had been diagnosed with invasive primary cancer from 1 month to 42 years before HUNT-2 according to CRN and self-report. An overall random sample of controls without cancer five times larger than the sample of cases (N = 1,670 were drawn from the parent cohort. Results The cancer sample comprised 128 STS and 206 LTS. For most variables no significant differences were observed between LTS and STS. LTS were significantly more women, and cases with gynaecological cancer, with physical impairment and more thyroid diseases compared to STS. When comparing all the survivors with controls, the survivors showed significantly higher rate of pensioning, decreased self-rated health, more physical impairment and thyroid diseases, daily use of medication and psychotropics and higher level of anxiety and Framingham Risk score. Multivariate logistic regression analysis showed that increasing age, being female, physical impairment and thyroid diseases all were significantly associated with being survivor versus controls. Conclusion STS and LTS showed mostly similar situation. Compared to controls, the survivors reported somewhat poorer physical and mental health, but these differences were of doubtful clinical significance.

    Full Text Available Abstract Background This study explores the role of pleasure in decision making. Results In Experiment 1, 12 subjects were presented with a questionnaire containing 46 items taken from the literature. Twenty-three items described a situation where a decision should be made and ended with a suggested solution. The other items served as filler items. The subjects were requested not to make a decision but to rate the pleasure or displeasure they experienced when reading the situation described in the item. The subjects' ratings were then compared to the decisions on the same situations made by the other subjects of the studies published by other workers. The ratings of pleasure/displeasure given by our subjects correlated significantly with the choices published by other authors. This result satisfies a necessary condition for pleasure to be the key of the decision making process in theoretical situations. In Experiment 2, a new group of 12 subjects rated their experience of pleasure/displeasure when reading various versions of 50 situations taken from daily life where an ethical decision had to be made (Questionnaire I including 200 items. This was followed by a multiple-choice test with the 50 situations (Questionnaire II using the same 200 items and offering the various behaviors. Subjects tended to choose ethical and unethical responses corresponding to their highest pleasure rating within each problem. In all cases the subjects' behavior was higher than chance level, and thus, followed the trend to maximize pleasure.

    2017-09-01

    Full Text Available The article analyzes the transformation of the methodological toolkit for teaching humanities and sciences in the Russian Federation. The method of case study, being widely spread in modern higher education research, is used as an example to illustrate the attempts to implement the best practices of foreign educational technology into tertiary academic process in Russia. The author provides some historical aspects of introducing case studies in modern teaching practice. The article features peculiarities of the Soviet approach to the structure of cases. Content analysis helps identify similarities and differences in Soviet/post-Soviet approaches to case study construction and brings into focus the problem points which reveal misinterpretation and/or misuse of didactic materials designated as cases. The approach suggested in the article implies presenting the content of a case study as a collection of documents related to a certain topic. The case study "Istanbul in the life and work of the artist Martiros Saryan" demonstrates that a case can have invariable and variable parts to reflect the specificity of the didactic task within the discipline. Such approach is expected to support students’ cognitive activity, develop creativity in searching additional sources and missing materials, improve efficiency of students’ autonomous work on solving complex problem solution.

    Hollingworth, P J

    1978-08-01

    The Australian Royal Commission on Human Relationships summarized the problems of adolescents and family planning by declaring there is a level of teenage sexual activity that cannot be ignored. Young single people have a low rate of effective contraception. Teenagers suffer a very high proportion of unwanted pregnancies and abortions. Placing the ethical questions in a contemporary social context enables society to face the issues in a practical, realistic fashion. Historically preserved traditions, like the taboo against premarital sex, are and will continue to be important in the bonding of families, individuals, and societies. A situational ethic applies to changes in the social fabric and addresses them. Society has changed from rural to urban, from agrarian to technological, from literacy to mass media, from superstitious knowledge of reproduction to scientific methods of birth control. The realities of change should be faced with a sense of ethics that is grounded in tradition and adjusted to the needs of the actual situation which is that too many teenagers have too many unwanted pregnancies. They can be helped.

    The observation and monitoring of traffic with smart visions systems for the purpose of improving traffic safety has a big potential. For example embedded vision systems built into vehicles can be used as early warning systems, or stationary camera systems can modify the switching frequency of signals at intersections. Today the automated analysis of traffic situations is still in its infancy - the patterns of vehicle motion and pedestrian flow in an urban environment are too complex to be fully understood by a vision system. We present steps towards such a traffic monitoring system which is designed to detect potentially dangerous traffic situations, especially incidents in which the interaction of pedestrians and vehicles might develop into safety critical encounters. The proposed system is field-tested at a real pedestrian crossing in the City of Vienna for the duration of one year. It consists of a cluster of 3 smart cameras, each of which is built from a very compact PC hardware system in an outdoor capable housing. Two cameras run vehicle detection software including license plate detection and recognition, one camera runs a complex pedestrian detection and tracking module based on the HOG detection principle. As a supplement, all 3 cameras use additional optical flow computation in a low-resolution video stream in order to estimate the motion path and speed of objects. This work describes the foundation for all 3 different object detection modalities (pedestrians, vehi1cles, license plates), and explains the system setup and its design.

    Aim: To compare the existing maternal and fetal outcomes in Asian Indian women with or without gestational diabetes mellitus (GDM) before the development of the Women in India with GDM Strategy (WINGS) GDM model of care (MOC). Materials and Methods: Records of pregnant women were extracted retrospectively from three maternity centers in Chennai. GDM was diagnosed using the International Association for Pregnancy Study Groups criteria or the Carpenter and Coustan criteria. Demographic details, obstetric history, antenatal follow-up, treatment for GDM, and outcomes of delivery were collected from the electronic medical records. Results: Of the 3642 records analyzed, 799 (21.9%) had GDM, of whom 456 (57.1%) were treated with insulin and medical nutrition therapy (MNT), 339 (42.4%) with MNT alone, and 4 (0.5%) with metformin. Women with GDM were older than those without (28.5 ± 4.5 vs. 27.1 ± 4.5 years; P management of GDM. Data from this retrospective study will form the basis for the development of the WINGS GDM MOC, which will address these gaps in GDM care in low-resource settings. PMID:27366715

    Geographically, Turkey is situated in an area where malaria is very risky. The climatic conditions in the region are suitable for the malaria vector to proliferate. Due to agricultural infrastructural changes, GAP and other similar projects, insufficient environmental conditions, urbanization, national and international population moves, are a key to manage malaria control activities. It is estimated that malaria will be a potential danger for Turkey in the forthcoming years. The disease is located largely in south-eastern Anatolia. The Diyarbakir, Batman, Sanliurfa, Siirt, and Mardin districts are the most affected areas. In western districts, like Aydin and Manisa, an increase in the number of indigenous cases can be observed from time to time. This is due to workers moving from malaria districts to western parts to final work. Since these workers cannot be controlled, the population living in these regions get infected from indigenous cases. There were 84,345 malaria cases in 1994 and 82,096 in 1995, they decreased to 60,884 in 1996 and numbered 35,456 in 1997. They accounted for 36,842 and 20,963 in 1998 and 1999, respectively. In Turkey there are almost all cases of P. vivax malaria. There are also P. vivax and P. falciparum malaria cases coming from other countries: There were 321 P. vivax cases, including 2 P. falciparum ones, arriving to Turkey from Iraq in 1995. The P. vivax malaria cases accounted for 229 in 1996, and 67, cases P. vivax including 12 P. falciparum cases, in 1997, and 4 P. vivax cases in 1998 that came from that country. One P. vivax case entered Turkey from Georgia in 1998. The cause of higher incidence of P. vivax cases in 1995, it decreasing in 1999, is the lack of border controls over workers coming to Turkey. The other internationally imported cases are from Syria, Sudan, Pakistan, Afghanistan, Nigeria, India, Azerbaijan, Malaysia, Ghana, Indonesia, Yemen. Our examinations have shown that none of these internationally imported cases

  3. A study evaluating if targeted training for startle effect can improve pilot reactions in handling unexpected situations in a flight simulator

    Gillen, Michael William

    Recent airline accidents point to a crew's failure to make correct and timely decisions following a sudden and unusual event that startled the crew. This study sought to determine if targeted training could augment decision making during a startle event. Following a startle event cognitive function is impaired for a short duration of time (30-90 seconds). In aviation, critical decisions are often required to be made during this brief, but critical, time frame. A total of 40 volunteer crews (80 individual pilots) were solicited from a global U.S. passenger airline. Crews were briefed that they would fly a profile in the simulator but were not made aware of what the profile would entail. The study participants were asked to complete a survey on their background and flying preferences. Every other crew received training on how to handle a startle event. The training consisted of a briefing and simulator practice. Crew members (subjects) were either presented a low altitude or high altitude scenario to fly in a full-flight simulator. The maneuver scenarios were analyzed using a series of one-way ANOVAs, t-tests and regression for the main effect of training on crew performance. The data indicated that the trained crews flew the maneuver profiles significantly better than the untrained crews and significantly better than the Federal Aviation Administration (FAA) Airline Transport Pilot (ATP) standards. Each scenario's sub factors were analyzed using regression to examine for specific predictors of performance. The results indicate that in the case of the high altitude profile, problem diagnosis was a significant factor, in the low altitude profile, time management was also a significant factor. These predicators can be useful in further targeting training. The study's findings suggest that targeted training can help crews manage a startle event, leading to a potential reduction of inflight loss of control accidents. The training was broad and intended to cover an

    In a double-blind study on student nurses the curves of three affectivity components and the pulse rate under exam conditions were observed. One group had received 1-(o-allyloxy-phenoxy)-3-isopropylamino-propan-2-ol hydrochloride (oxprenolol, Trasicor and the other group a placebo. In the examination stress the affectivity component "aggression" was particularly obvious. With placebo the states and actions of aggression were more extreme than in the oxprenolol group. It appeared that the severe affectivity inclinations resulted in a reduction of examination performance. Under oxprenolol, in accordance with recently published results, there was no decrease in performance under exam conditions. Quite the opposite: as it seems to curb extreme affectivity inclinations the decreases in performance connected with them are often prevented.

Materials and Methods: Records of pregnant women were extracted retrospectively from three maternity centers in Chennai. GDM was diagnosed using the International Association for Pregnancy Study Groups criteria or the Carpenter and Coustan criteria. Demographic details, obstetric history, antenatal follow-up, treatment for GDM, and outcomes of delivery were collected from the electronic medical records. Results: Of the 3642 records analyzed, 799 (21.9% had GDM, of whom 456 (57.1% were treated with insulin and medical nutrition therapy (MNT, 339 (42.4% with MNT alone, and 4 (0.5% with metformin. Women with GDM were older than those without (28.5 ± 4.5 vs. 27.1 ± 4.5 years; P < 0.001 and had higher mean body mass index at first booking (26.4 ± 5.2 kg/m2 vs. 25.2 ± 5.1 kg/m2; P < 0.001. Rates of cesarean section (26.2% vs. 18.7%; P < 0.001, preeclampsia (1.8% vs. 0.8%; P = 0.04, and macrosomia (13.9% vs. 10.8%; P = 0.02 were significantly higher among women with GDM. In women with GDM treated with insulin and MNT, emergency cesarean section (16.2% vs. 36.6%; P < 0.0001, preeclampsia (0.7% vs. 3.2%; P = 0.015, and macrosomia (9.9% vs. 18.6%; P = 0.0006 were significantly lesser compared to those treated with MNT alone. Conclusion: Pregnancy outcomes were in general worse in GDM women. Treatment with insulin was associated with a significantly lower risk of complications. However, in countries with limited access to insulin and other medicines may lead to poor follow-up and management of GDM. Data from this retrospective study will form the basis for the development of the WINGS GDM MOC, which will address these gaps in GDM care in low-resource settings.

    The subjects of this study were 405 Japan Medical Association authorized industrial physicians, Community Industrial Physicians (CIPs), who belonged to the Shinjuku, Nakano, and Suginami Words' regional medical associations in the jurisdiction of the Shinjuku Labor Standards Inspection Office. Between November and December, 2003, the CIPs were mailed a questionnaire requesting information about their affiliations and activities, and as indicators of their willingness to participate in Community Occupational Health Services, they were asked about the pros and cons of having their names published as Industrial Physicians, and/or practitioners for Regional Occupational Health Centers, or Regular Health Checks. 152 replies were received, effective response rate of 37.5%, and among these 94 replies were from CIPs who work as part-time industrial physician. Overall, CIPs attend Community Occupational Health Services (COHS) voluntarily, and wish to participate in them more in the future. CIPs who work as part-time industrial physician have knowledge of working safety and hygiene and are providing advice and guidance on working conditions and environments. Also, they are well informed about support services for small and medium-sized enterprises which is thought to be connected with their willingness to participate in COHS. Furthermore, it is important that part-time CIPs activities are appreciated by their respective place of work.

    Full Text Available Family agriculture is a fundamental pillar in the construction of agroecological agri-food alternatives fostering processes of sustainable rural development where social equity represents a central aspect. Despite agroecology’s critical openness, this area has not yet incorporated an explicit gender approach allowing an appropriate problematization and analysis of the cultural inequalities of gender relations in agriculture, women’s empowerment processes and their nexus with sustainability. This work presents an organized proposal of indicators to approach and analyze the degree of peasant women’s equity and empowerment within a wide sustainability framework. After a thorough bibliographical review, 34 equity and empowerment indicators were identified and organized into six basic theoretical dimensions. Following the collection of empirical data (from 20 cacao-producing families, the indicators were analyzed and reorganized on the basis of hierarchical cluster analysis and explanatory interdependence into a new set of six empirical dimensions: (1 access to resources, education and social participation; (2 economic-personal autonomy and self-esteem; (3 gender gaps (labor rights, health, work and physical violence; (4 techno-productive decision-making and remunerated work; (5 land ownership and mobility; and (6 diversification of responsibilities and social and feminist awareness. Additionally, a case study is presented that analyzes equity and empowerment in the lives of two rural cacao-producing peasant women in Ecuador.

    This paper addresses a problem of assigning electric power repair crews and depots to various locations (cells) in a damaged area during emergency situations such as natural disasters. The problem takes into account the damage levels and consequent demand for various resources at different cells in the area, along with the capacity restrictions of the depots. Two mixed integer quadratic programming models - one for single resource and another for multiple resources allocation are presented in this paper. The objective is to locate the depots, and assigning the crews and other resources to depots to various cells, at a minimum cost. The problem is solved optimally for various dimensions of the problem (e.g., number of cells in the region, number of depots considered and the number of resources) for a limited instance. (UK)

    2015-10-01

    In the UK the publication of the Health Select Committee Report highlighted the need to incorporate human factors training in health care education. In response there has been a rise in health care professional training in human factors, focusing on non-technical skills, such as teamwork, leadership and situational awareness. Using simulation and contextualised learning, we have developed a non-technical skills programme for undergraduate medical students that introduces situational awareness training in the first year. Early integration of human factors into the undergraduate programme can be built upon in a constructivist approach throughout the undergraduate curriculum. Initially no formal ethical approval was required as this was an integral part of the undergraduate teaching programme and did not involve patients; however, ethical approval was gained for the analyses of this session from the local University Research Ethics Committee. Approval included the information sheets and consent forms provided to students, which permitted use of data 'in future posters/publications/presentations'. Students were introduced to hazards and cues that they may find in clinical areas, encouraged to explore the simulated clinical areas gathering information, interpret their findings and then consider future states. There has been a rise in health care professional training in human factors, focusing on non-technical skills Initial feedback from both the students and the tutors involved has been positive. In addition, the opportunity for linking this to other non-technical skills developments in different clinical settings and in interprofessional settings is being considered. The next stage is to explore students' perceptions of this session and their learning through questionnaires and focus-group interviews before developing further. © 2015 John Wiley & Sons Ltd.

    This paper studies the dangerous situation (DS) in a synchronized flow model. The DS on the two branches of the fundamental diagram are investigated, respectively. It is shown that different relationship between DS probability and the density exists in the synchronized flow and in the jams. Moreover, we prove that there is no DS caused by non-stopped car although the model itself is a non-exclusion process. We classify the DS into four sub-types and study the probability of these four sub-types. The simulation result is consistent with the real traffic.

Replacement of the currently required manual with an automatically generated link, which is based on content and semantics, requires the use of a suitably structured vocabulary for a machine-readable description of object content. Aim of this study is to compile the existing taxonomies and ontologies used for the annotation of medical content and learning resources, to compare those using selected criteria, and to verify their suitability in the context described above.Methods: Based on a systematic literature search, existing taxonomies and ontologies for the description of medical learning resources were identified. Through web searches and/or direct contact with the respective editors, each of the structured vocabularies thus identified were examined in regards to topic, structure, language, scope, maintenance, and technology of the taxonomy/ontology. In addition, suitability for use in the Semantic Web was verified.Results: Among 20 identified publications, 14 structured vocabularies were identified, which differed rather strongly in regards to language, scope, currency, and maintenance. None of the identified vocabularies fulfilled the necessary criteria for content description of medical curricula and learning resources in the German-speaking world. Discussion: While moving towards Web 3.0, a significant problem lies in the selection and use of an appropriate German vocabulary for the machine-readable description of object content.

    Autonomous situational awareness (SA) requires an ability to learn situations. It is mathematically difficult because in every situation there are many objects nonessential for this situation. Moreover, most objects around are random, unrelated to understanding contexts and situations. We learn in early childhood to ignore these irrelevant objects effortlessly, usually we do not even notice their existence. Here we consider an agent that can recognize a large number of objects in the world; in each situation it observes many objects, while only few of them are relevant to the situation. Most of situations are collections of random objects containing no relevant objects, only few situations "make sense," they contain few objects, which are always present in these situations. The training data contains sufficient information to identify these situations. However, to discover this information all objects in all situations should be sorted out to find regularities. This "sorting out" is computationally complex; its combinatorial complexity exceeds by far all events in the Universe. The talk relates this combinatorial complexity to Gödelian limitations of logic. We describe dynamic logic (DL) that quickly learns essential regularities-relevant, repeatable objects and situations. DL is related to mechanisms of the brain-mind and we describe brain-imaging experiments that have demonstrated these relations.

    To develop and verify a driver assistance function, working on the electric power steering of passenger cars, to support the driver on handling critical understeer situations. The main objectives of the so-called understeer assistance are reinforcing the driver's awareness of the driving conditions and giving support to handle the situation correctly without inducing irritation by abnormal steering behavior. The system was designed in consideration of psychological aspects of human decision making while operating a vehicle in unfamiliar understeer situations. Using a comparison of vehicle dynamics with a reference model computed in the car, the level of understeer is calculated. Depending on the understeer level, the steering wheel restoring torque is increased while a vibration is applied to the steering wheel at the same time. To verify the achievement of the objectives, the standard steering system is compared to the developed understeer assistance in an active driving study on a test track. Not only objective measurement data but also subjective ratings delivered by 63 unbiased participants were used. The subjects follow the offered steering recommendation by steering less when the assistance function is activated (Δγmax = 44.38°, p = 2.5°·10⁻³%). In the sequel, an enhanced vehicle reaction arises that is validated by analyzing the achieved maximum lateral offset (ΔSy,res = 0.16m, p = 0.07%). In addition, the evaluation of subjective ratings clearly indicates a better awareness of the understeer situation with the assistance function (χ= +0.44, p = 0.89%). Furthermore the subjects rate the understeer assistance better than the standard steering system (χ= +0.43, p = 3.03%). By measuring vehicle data and eliciting subjective opinions of the participants, the effectiveness regarding an improved handling of an understeering vehicle as well as the acceptance of the understeer assistance by the driver is confirmed.

    Municipal plans of energy utilization enable the recognition of the amount and causer of the energy demand in a community or in an administrative district, a more efficient design of energy utilization and an enhanced use of renewable energies. The author of the contribution under consideration reports on the use of the extensive data base of the master plan for a development of plans for energy utilization. In analyzing the current situation, a detailed and spatially resolved presentation of the heat demand and electricity demand in the sectors of housing, industry and trade, commerce and services is performed. The potentials and the expected expansion of renewable energies are shown on the EEG database of the Research Center for Energy Economics (Munich, Federal Republic of Germany). Subsequently, regional targets are defined and derived from the municipal need for action. The municipal need for action can be incorporated into plans for energy utilization.

Situational Guilt Inventory (SGI) for the 37 was developed and administered to 500 Japanese adolescents. Factor analysis found four factors: hurting others, inconsiderate to others, acting selfishly, and debt feeling toward others. SGI scores had positive correlations with private and public self-consciousness and depression. However, correlations with the Big Five were low, none higher than .2, except those with conscientiousness. The factors were similar to those of Dimension of Conscience Questionnaire (DCQ; Gore & Harvey, 1995) and Situational Guilt Scale (SGS; Klass, 1987), except that they do not have the fourth: debt feeling. These results showed some characteristics of guilt among Japanese people, as well as reliability of the inventory.

    This article reports an analysis of the concept of situational awareness in nursing. Situational awareness is a fundamental and well-understood concept used to maintain operational safety in high reliability organizations; however, it has not been studied in nursing. Nurses play a critical role in providing vigilance in health care and what they do or fail to do is directly related to patient outcomes. Multiple databases, including PubMed, CINAHL, JSTOR, and Google Scholar, were searched with the term, 'situational awareness'. The primary search, used to identify all uses of the concept, did not employ date criteria. A secondary search for articles measuring situational awareness as an independent or dependent variable was completed using 2009-2011 articles. Concept Analysis. The concept of situational awareness was examined using Walker and Avant's eight step method of analysis. Three defining attributes of situational awareness include perception, comprehension, and projection. Situational awareness is defined as the perception of the elements in the environment in a volume of time and space, the comprehension of their meaning and the projection of their status in the near future. Although situational awareness is related to other terms in nursing, there is increasing recognition that the concept, which is likely a consolidation of the related terms, has an impact on healthcare professionals. Failures in perception, comprehension, and/or projection can significantly reduce the accuracy and appropriateness of patient care decisions. Therefore, as a precursor to decision making, poor or inadequate levels of situational awareness present serious threats to patient safety. Situational awareness needs to be examined in a theoretical context, studied systematically and openly recognized as a key factor in the delivery of safe patient care. © 2013 John Wiley & Sons Ltd.

    Purpose: To optimize the MR sequences parameter for monitoring hyperthermic effects in the tissue during laser induced thermotherapy (LITT). Material and methods: Experimental studies were performed for the evaluation of MR-thermometry using a contrast-agent-water solution and a pig-liver. A T{sub 1}-weighted TurboFLASH sequence and a FLASH-3D sequence were used. The turboFLASH sequence was used with various T{sub 1} settings (between 100 and 1250 ms). MR findings were correlated with temperature measurements using a fluoride optical temperature measuring system in a distance of 1, 2, and 5 cm from the laser applicator. Results: Using the contrast-agent-water solution demonstrated the temperature sensitivity of both sequences. In vitro evaluations using pig liver demonstrated a near linear increase of signal versus increasing tissue temperatures in a distance of 1 cm to the tip of the laser applicator. Optimal visualization of the temperature effects was obtained using a T{sub 1} between 100 ms and 400 ms. Using the FLASH-2D sequence a signal loss was documented at a T{sub R} of 110 ms. Conclusion: MR-thermometry using sequentially TurboFLASH and FLASH-2D sequences allowed a non-invasive monitoring of the laser induced temperature changes. (orig.)

    Full Text Available Any organization is confronted with a multitude of problems in a dynamic andcomplex environment. These problems can be independent, but, many times,they are interconnected. In this myriad of situations, it is difficult to identify thecausality relations between problems, which, logically, should also determinethe solving order. An organization is faced with a cash crisis, a substantialloss of clients, production equipment wear, poorly qualified personnel, andunsuitable products from a quality- related perspective. And in this context,what is the original problem, primary, and through its solving, the solution tothe other problems could be found? Is this the loss of clients, or cash crisis?Are we facing a cash crisis because the products are of poor quality anddon’t sell, or is it because we are facing a cash crisis we are unable to investin research- development, in order to increase product quality?We will try to find an answer to such dilemmas in this material. The problemis not a new one in the specialized literature. In the first part of the article wewill present a couple of previous solutions this problem has been given, andduring the second part we will propose a model derived from those known inthe specialized literature.

    Research has shown that acute exercise reduces urges for chocolate in normal weight people. This study aimed to examine the effects of an acute exercise bout on urges to consume sugary snacks, affect as well as 'psychological and physiological responses' to stress and a 'sugary snack cue', in overweight individuals. Following 3 days of chocolate-abstinence, 47 overweight, sugary snack consumers were assessed, in 2 randomly ordered conditions, in a within-subject design: 15-min brisk walk or passive control. Following each, participants completed 2 tasks: Stroop color-word interference task, and handling sugary snacks. Urges for sugary snacks, affective activation and valence were assessed. ANOVAs revealed significant condition x time interaction effects for: urges to consume sugary snacks, affective valence and activation. Obtained data show that exercise reduces urges for sugary snacks and attenuates urges in response to the stress situation and the cue in overweight people.

    The Commander, United States Strategic Command (CDRUSSTRATCOM) accepted responsibility for sharing space situational awareness (SSA) information/services with commercial & foreign entities from the US Air Force on 22 Dec 09 (formerly the Commercial & Foreign Entities Pilot Program). The requirement to share SSA services with non-US Government (USG) entities is derived from Title 10, United States Code, Section 2274 (2010) and is consistent with the new National Space Policy. US Strategic Command’s (USSTRATCOM’s) sharing of SSA services consists of basic services (Two-Line Elements, decay data and satellite catalog details) available on www.space-track.org and advanced services (conjunction assessment, launch support, etc) available with a signed agreement. USSTRATCOM has requested USG permission to enter into international agreements to enable SSA data exchange with our foreign partners. USSTRATCOM recently authorized Joint Functional Component Command for Space (JFCC SPACE) to share Conjunction Summary Messages (CSMs) with satellite owner/operators whose satellites have been identified as closely approaching another space object. CSMs contain vector and covariance data computed using Special Perturbations theory. To facilitate the utility of the CSMs, USSTRATCOM has and is hosting CSM Workshops to ensure satellite operators fully understand the data contained in the CSM in order to provide an informed recommendation to their leadership. As JFCC SPACE matures its ability to accept ephemeris data from a satellite operator, it will be necessary to automatically transfer that data from one security level to another. USSTRATCOM and Air Force Space Command are coordinating the integration of a cross domain solution that will allow JFCC SPACE to do just that. Finally, USSTRATCOM is also working with commercial and governmental organizations to develop an internationally-accepted conjunction assessment message.

  20. Investigating Situational Interest in Primary Science Lessons

    Pupils' interest has been one of the major concerns in science education research because it can be seen as a gateway to more personalised forms of interest and motivation. However, methods to investigate situational interest in science teaching and learning are not broadly examined. This study compares the pupils' observed situational interest and their expressed situational interest. One class of Finnish fourth-graders (N = 22, age 9-10 years) participated in a heat transfer lesson. The lesson encompassed an interactive demonstration with a thermal camera, teacher-led discussions and the conduct and presentation of a collaborative inquiry task. Pupils expressed their interest levels (scale: 1 = very boring, 5 = very interesting) by using an electronic response system called a 'clicker'. The measurement took place 15 times during the lesson, with 1 measurement being just a rehearsal. The lesson was video recorded, and visible aspects of interest at the measurement time points were analysed. Reported and observational data were compared. In most cases, the observations did not yield data compatible with the pupils' own evaluations, indicating that most pupils' expressed interest is not easily interpreted through observation of their facial expressions and behaviour. In general, the interest of the group as a whole seems to diminish during the lesson. We argue that in order to maintain and increase pupils' interest, their evaluations should be taken into account in lesson planning. Video-based research might also be further enriched and validated by employing the participants' own expressions. The clicker is a suitable means of collecting primary pupils' experiences concerning their interest levels.
