We raised the main factors leading todifficulties and constraints in this activity, especially with regard to biomechanical conditions. Inaddition, the study presents a structured approach as the requirements of ergonomics Frenchconfronting the real problems of welders, which are not in work, performed by outsideconsultants who, in a sense, hide real conditions of work. It was through a case study, the majority ofwork in both the scientific literature on the work of external consulting expertise. The constraints of thewelders are characterized as postural and behavioral risks, not showing that behind these, there arecharacteristics of requirements the solder that force the worker to adopt efforts biomechanical posture to which they are unable to behave properly as stated in the research.

  3. Conditional Electrical Stimulation in Animal and Human Models for Neurogenic Bladder: Working Toward a Neuroprosthesis.

    2016-12-01

    Sacral neuromodulation has had a tremendous impact on the treatment of urinary incontinence and lower urinary tract symptoms for patients with neurologic conditions. This stimulation does not use real-time data from the body or input from the patient. Incorporating this is the goal of those pursuing a neuroprosthesis to enhance bladder function for these patients. Investigators have demonstrated the effectiveness of conditional (also called closed-loop) feedback in animal models as well as limited human studies. Dorsal genital nerve, pudendal nerve, S3 afferent nerve roots, S1 and S2 ganglia have all been used as targets for stimulation. Most of these have also been used as sources of afferent nerve information using sophisticated nerve electrode arrays and filtering algorithms to detect significant bladder events and even to estimate the fullness of the bladder. There are problems with afferent nerve sensing, however. Some of these include sensor migration and low signal to noise ratios. Implantable pressure sensors have also been investigated that have their own unique challenges, such as erosion and sensor drift. As technology improves, an intelligent neuroprosthesis with the ability to sense significant bladder events and stimulate as needed will evolve.

  4. Female leaders’ experiences of psychosocial working conditions and its health consequences in Swedish public human service organizations

    Full Text Available Municipal workplaces have high levels of sickness absence, and deterioration of the psychosocial work environment has been most pronounced for women and employees in this sector of Swedish working life. This study explores how female leaders in one rural municipality in Sweden experience their psychosocial working conditions and its health consequences. Interviews were carried out with 20 female leaders. Data were analyzed with a content analysis method using major dimensions of work stress models. These were job demands, job control, job resources, social support, and its health consequences. The analysis shows that the leaders experience high and conflicting job demands, limited possibilities to influence their work situation, insufficient job resources and social support, and limited time for their own health promotion. However, the leaders experience possibilities to develop skills in their jobs and opportunities to participate in educational programs. The analyses confirm the need for improvements in the prerequisites for female leaders in public human service organizations. It is important to improve female leaders’ psychosocial working conditions by implementing a more narrow control range, increased personal and economical recourses, leadership support, and leader development programs.

    Full Text Available The objective of this research was to analyze the human factors and the work conditions in clear-cutting operations using chainsaws in mountainous areas. Data were colected in a forestry company in Minas Gerais, Brazil, by interviews with 29 chainsaw operators. The results indicated that the operators average age was 32.3 years, height 1.68m and body weight 64.4Kg. The average job time in the company was 112 months and the average time of chainsaw operation experience was 81.5 months. Most (93.1% were dexterous and 6.9% were left-handed. The high incidence of backache (41.4% indicated that the task demands an overload of lumbar column, so that the company should take preventive measures to avoid backaches, using educational strategies or changing the opera-tional system. The high level of accidents (44.8% indicated that some precautions are needed to im-prove work safety.

  14. Working conditions, compensation and absenteeism.

    Science.gov (United States)

    Ose, Solveig Osborg

    2005-01-01

    This paper examines absence behaviour in relation to the working environment. A theoretical model is built in order to separate the effects of voluntary absences and absences related to ill health, where health effects are assumed to be tied to working conditions. This model is based on the Shapiro and Stiglitz efficiency wage model. In addition, work environment is introduced as a part of the compensation package. The model gives a testable hypothesis of compensating wage differentials. A panel of quarterly firm level data from 1990 to 1998 are used and the theoretical model is supported by the empirical findings. The result indicates that the workers may not be fully compensated when experiencing high levels of noise in the work area, or when the job involves a high degree of monotonous work, heavy or frequent lifting or poor work postures. Ill health, and thus increased long-term absence, is not highly related to economic variables. However, long-term absence is relatively higher if the firm is troubled with many accidents or near misses. In addition, disamenities for which workers are not fully compensated cause ill health and increased long-term absence.

    In premises for blood conservation, production of dry human plasma and infusion solutions "notwithstanding the permanent measures for desinfection, new bacterial contamination occurs from time to time and whose source are the casings and material originating from non-sterile environment. Bacteriological control, which has primarily a preventive character, enables a due forecast for measures to be undertaken by the appropriate desinfection of the working surfaces and air, satisfactory conditions of aseptic work can be maintained. General hygiene should be paid attention to as well as mechanical cleansing of premises, avoidance of groups for lunch-time etc., since the treatment by desinfectors would not be sufficient for maintenance of aseptic working conditions. In order to prevent the transmission of bacterial contamination, premises for blood conservation should be strictly separated from other operations and also prevent the unnecessary movements of personnel through corridors. The results of the bacteriological control of the personnel show that greater attention should be paid to their health care since the workers there work in closed aseptic systems and thus avoid them as a bacteria transmittors in respect to danger of blood and dry human plasma contamination. It is also necessary to efficiently educate the personnel for work in aseptic conditions and also increase their elementary knowledge from bacteriology and hygiene. The bacterial skin-flora on the spot of donor's venepuncture also presents a certain danger for blood contamination. Therefore, it is necessary to establish the most optimal manner of skin desinfecate together with the most appropriate means having a fast bactericidal and fungicidal action. It would also be useful, on the basis of further test, to suggest certain standard for an allowed number of conditionally pathogenic and saprophytic microorganisms which would be used by the instutions performing the blood transfusion and production of

    1994-03-01

    For the first time in Albania, a large-scale study investigating teachers' working conditions was conducted. 349 teachers from many parts of the country and from all school levels answered an extensive questionnaire, providing a comprehensive description of their working situation. As data for parts of the study exist from the USA, Germany, Singapore, England, and Poland, results could be discussed in comparison to the conditions in these countries, showing that self-reported job satisfaction and engagement in effective classroom practices is relatively high among Albanian teachers, while the economic and physical conditions are bad. Stepwise regression analyses reveal that the items measuring professional autonomy account for a considerable part of the variance of the job satisfaction measure; while work efficiency is mainly predicted by items measuring social support and, again, professional autonomy.

    Full Text Available The aim of this article is work modelling of superheater SH3. It is made of the austenitic stainless steel Super 304H. Its design temperature T is 604 C, and the design pressure P acting on the inner surface of the pipes is 284 bar. The high temperature is the reason of the superheater work under creep conditions. In this article calculations of the optimally mounted coil superheater SH3 are presented. The calculations are carried out first on the basis of the applicable European standards and with the help of the Auto Pipe program. Then, calculations are performed using the ANSYS program based on conducted creep tests and proposed creep equation. The coefficients in creep equation are determined based on the research conducted at the Instytut Metalurgii Żelaza in Gliwice. The model approximates the creep strain as the function of time and stress and this function is presented in the form of a three-dimensional surface . The results of calculations by both methods will be compared and conclusions will be presented. The performed analyzes can estimate the superheater coil remnant life and the usage after the selected time of its operation.

    Full Text Available Every institution should monitor its productivity. If productivity is decreasing, particular measures should be taken. The aim of the paper was to analyse the situation in four institutions by means of questionnaires filled in by 135 respondents, and to point to the problems that were detected through questionnaires. To increase productivity, high levels of worker responsibility should be introduced within the framework of work process, taking into account work potentials of workers, quantity and quality of work. From the results obtained through this survey it was noted that an adequately motivated worker in comfortable work environment is willing to be fully devoted to work and achieve best results, thus ultimately contributing to the overall productivity. There should be a tendency to adequately reward every worker who is willing to commit to work during full working hours and to be responsible for his or her work. Every type of work can be defined by productivity function.

  16. Supramodal parametric working memory processing in humans.

    Science.gov (United States)

    Spitzer, Bernhard; Blankenburg, Felix

    2012-03-07

    Previous studies of delayed-match-to-sample (DMTS) frequency discrimination in animals and humans have succeeded in delineating the neural signature of frequency processing in somatosensory working memory (WM). During retention of vibrotactile frequencies, stimulus-dependent single-cell and population activity in prefrontal cortex was found to reflect the task-relevant memory content, whereas increases in occipital alpha activity signaled the disengagement of areas not relevant for the tactile task. Here, we recorded EEG from human participants to determine the extent to which these mechanisms can be generalized to frequency retention in the visual and auditory domains. Subjects performed analogous variants of a DMTS frequency discrimination task, with the frequency information presented either visually, auditorily, or by vibrotactile stimulation. Examining oscillatory EEG activity during frequency retention, we found characteristic topographical distributions of alpha power over visual, auditory, and somatosensory cortices, indicating systematic patterns of inhibition and engagement of early sensory areas, depending on stimulus modality. The task-relevant frequency information, in contrast, was found to be represented in right prefrontal cortex, independent of presentation mode. In each of the three modality conditions, parametric modulations of prefrontal upper beta activity (20-30 Hz) emerged, in a very similar manner as recently found in vibrotactile tasks. Together, the findings corroborate a view of parametric WM as supramodal internal scaling of abstract quantity information and suggest strong relevance of previous evidence from vibrotactile work for a more general framework of quantity processing in human working memory.

    In order to realize “the product life cycle with respect for human nature". we ought to make work design so that work environment should be configured to be sound in mind and body, with due consideration of not only physical but also mental factors from the viewpoint of workers. The former includes too heavy work, unreasonable working posture, local fatigue of the body, the safety, and working comfort, and the latter includes work motivation, work worthiness, stress, etc. For the purpose of evaluating the degree of working comfort and safety at human-oriented production lines, we acknowledged, for the work design, the effectiveness of the work designing technique with working time variation duly considered. And, we formulated a model for a mental factor experienced by workers from the degree of working delays. This study covers a work design technique we developed with the effect of the factor as the value of evaluation.

    One of the When designing a new heat exchanger it is necessary to consider all the conditions imposed on the exchanger and its desired properties. Most often the investigation of heat transfer is to find heat surface. When applying exchanger for proposed hot air engine, it will be a counter-flow heat exchanger of gas - gas type. Gas, which transfers the heat will be exhaust gas from the combustion of biomass. An important step in the design and verification is to analyze exchanger designed using numerical methods, the verification of the correctness of design and verification of boundary conditions which include temperatures, flow rates and pressure drops. Due to the fact that the heat transfer in the heat exchanger is a three-dimensional plot and timeindependent, the system is described by partial differential equations that need to be solved by numerical methods.

    Full Text Available In this paper we researched the vehicle braking sense in three aspects of human, vehicle and environment and analysed their impacts on brake feeling. Through the real vehicle test we analysed the relationship among pedal force, pedal travel and deceleration. We used dynamometer test method to study the brake noise question. We designed a fixture which could imitate the suspension and made the test more close to the true level. Moreover we discussed how to establish the evaluation system of vehicle braking condition. Through real vehicle test of braking, we can test and record the brake system parameters in the braking process under urban working conditions. We recorded the brake frequency, the change of brake speed and brake disc temperature. Meanwhile, based on the analysis of braking condition, we put forward the index of brake load to reflect the city’s traffic conditions. Experiment show that the braking condition and brake feel are related, braking condition also provides theoretical support for the design of brake system.

    To investigate the impact of rehabilitation measures on work ability and return to work (RTW), specifically the association between workplace rehabilitation/supportive conditions at work and work ability and RTW over time, among women on long-term sick leave. Questionnaire data were collected (baseline, 6 and 12 months) from a cohort of women (n = 324). Linear mixed models were used for longitudinal analysis of the repeated measurements of work ability index (WAI), work ability score and working degree. These analyses were performed with different models; the explanatory variables for each model were workplace rehabilitation, supportive conditions at work and time. The individuals provided with workplace rehabilitation and supportive conditions (e.g. influence at work, possibilities for development, degree of freedom at work, meaning of work, quality of leadership, social support, sense of community and work satisfaction) had significantly increased WAI and work ability score over time. These individuals scored higher work ability compared to those individuals having workplace rehabilitation without supportive conditions, or neither. Additionally, among the individuals provided with workplace rehabilitation and supportive conditions, working degree increased significantly more over time compared to those individuals with no workplace rehabilitation and no supportive conditions. The results highlight the importance of integrating workplace rehabilitation with supportive conditions at work in order to increase work ability and improve the RTW process for women on long-term sick leave.

    Perceived working conditions lead to various negative outcomes for employee behaviors, including turnover intentions. Although potential mediators for these relationships were previously identified, the importance of meaning of work has not yet been investigated. This study examines the role of this psychological resource as a mediator for the relationships between perceived working conditions and turnover intentions in a sample of 336 French workers from different job contexts. Results show that adverse working conditions were positively and significantly associated with turnover intentions. Meaning of work is negatively related to both perceived working conditions and turnover intentions. Mediation analyses for meaning of work demonstrated indirect effects of several adverse working conditions on turnover intentions. The role of meaning of work as a psychological resource for employees facing adverse working conditions is discussed, especially regarding its implications for research and practice within organizational contexts.

    Early leaving of workplace by work forces is one of the fundamental problems worldwide. Maintenance and enhancement of employees work ability are important for raising productivity. This study investigated the relationship between work ability index and physical working conditions and was carried out in 2013 on 641 workers at a manufacturing plant in Tehran. Work ability was assessed by the questionnaire of work ability index and the participants were classified into four work ability groups of poor, moderate, good, and excellent. Physical working conditions were evaluated by the MUSIC-Norrtalje questionnaire and the participants were classified into two groups with proper and poor physical working conditions. The mean score of work ability questionnaire was 42.40; and 2.5% (16 persons), 9.2% (59 persons), 38.2% (245 persons), and 50.1% (321 persons) of the participants were in poor, moderate, good, and excellent work ability groups, respectively. The mean score of physical working conditions questionnaire was 20.06. The results of logistic regression analysis showed that even after adjusting the confounding variables, a significant correlation existed between work ability and physical working conditions (p working conditions such as awkward postures, repetitive movements, load lifting, exposure to whole body vibration and so on with work ability. Therefore it seems that enhancement of the quality of physical working conditions may increase work ability.

    2010-01-01

    Workers participation in the management of employment and working conditions is an important determinant of both positive and negative effects of work on human health. Through a qualitative approach, this study analyzes the degree of control and influence that migrant workers in different Spanish cities have over their own working conditions (Immigration, Work, and Health [ITSAL] Project). Results showed that migrant workers had little influence on employment and working conditions. Immigrant workers are mostly interested in issues such as salaries, hiring, and hours of work. Fear of dismissal makes immigrant workers reluctant to demand improved working conditions. We received limited information about immigrant workers' understanding of their rights and their perceptions of the possibilities to influence working conditions through trade union activity. Informal social networks play an essential role in disseminating information on workers' rights, although the effect is not always positive. Unions need to increase attention to and adapt measures for this particularly vulnerable group of workers.

    2017-01-01

    In order to decrease human trafficking, health care workers should support the full decriminalization of prostitution. Similar to trafficking in other forms of labor, preventing trafficking in the sex trade requires addressing the different forms of marginalization that create vulnerable communities. By removing punitive laws that prevent reporting of exploitation and abuse, decriminalization allows sex workers to work more safely, thereby reducing marginalization and vulnerability. Decriminalization can also help destigmatize sex work and help resist political, social, and cultural marginalization of sex workers.

    Community-acquired pneumonia (CAP) is not considered a professional disease, and the effect of different occupations and working conditions on susceptibility to CAP is unknown. The aim of this study is to determine whether different jobs and certain working conditions are risk factors for CAP. Over a 1-year period, all radiologically confirmed cases of CAP (n=1,336) and age- and sex-matched controls (n=1,326) were enrolled in a population-based case-control study. A questionnaire on CAP risk factors, including work-related questions, was administered to all participants during an in-person interview. The bivariate analysis showed that office work is a protective factor against CAP, while building work, contact with dust and sudden changes of temperature in the workplace were risk factors for CAP. The occupational factor disappeared when the multivariate analysis was adjusted for working conditions. Contact with dust (previous month) and sudden changes of temperature (previous 3 months) were risk factors for CAP, irrespective of the number of years spent working in these conditions, suggesting reversibility. Some recent working conditions such as exposure to dust and sudden changes of temperature in the workplace are risk factors for CAP. Both factors are reversible and preventable.

    Full Text Available This paper examines philosophical, methodological and practical strategic aspects of library and information activity from the viewpoint of natural human and social factors. In contrast to traditional methodological patterns, real-life information problems and supportive methods of information seeking are stressed. The formulated conceptual framework is related to new competencies of information professionals, needs of information institutions and position of a human being in information processes. New methodological approach is outlined in models including factors with impact on a position of people in information work, human complexity and relationships of people and information. The resulting idea of human unity in information-related behaviour forms the vision of research directed to philosophy of a man in information science.

    Although cognitive neuroscience has made remarkable progress in understanding the involvement of the prefrontal cortex in human memory, the necessity of the orbitofrontal cortex for key competencies of working memory remains largely unexplored. We therefore studied human brain lesion patients to determine whether the orbitofrontal cortex is necessary for working memory function, administering subtests of the Wechsler memory scale, the Wechsler adult intelligence scale, and the n-back task to 3 participant groups: orbitofrontal lesions (n = 24), prefrontal lesions not involving orbitofrontal cortex (n = 40), and no brain lesions (n = 54). Orbitofrontal damage was reliably associated with deficits on neuropsychological tests involving the coordination of working memory maintenance, manipulation, and monitoring processes (n-back task) but not on pure tests of working memory maintenance (digit/spatial span forward) or manipulation (digit/spatial span backward and letter-number sequencing). Our findings elucidate a central component of the neural architecture of working memory, providing key neuropsychological evidence for the necessity of the orbitofrontal cortex in executive control functions underlying the joint maintenance, manipulation, and monitoring of information in working memory.

    The photoconductive antenna (PCA) is one of the most common devices to generate terahertz (THz) wave, whose radiation efficiency is largely determined by the working conditions. In order to improve the power of THz wave, the influence of pump laser and bias voltage on the intensity of the THz wave radiated by PCA was studied through experiment and the optimum working conditions of PCA was obtained through the theoretical analysis, these are the maximum safe voltage and saturated laser energy. Only under the optimum conditions can the signal-to-noise ratio(SNR)of THz wave radiated by PCA be the highest and the PCA would not breakdown.

    Hygienic assessment of working conditions of employees of the Omsk Regional Broadcasting Centre was performed on data of the analysis of materials of certification of workplaces. There were examined materials concerning 65 core profile workplaces, where 130 persons, including 35 women work. There was determined health risk for personnel in dependence on working conditions. The staff was noted to be exposed to the adverse impact of the following factors: chemical, physical (noise, general and local vibration, non-ionizing radiation, microclimate, lighting), severity and intensity ofwork. Class working conditions for 13,5% of workplaces on noise, 35.4% on non-ionizing radiation was assessed as a harmful of the first degree. Lightness indices at 78.5% of the workplaces did not meet the requirements of sanitary norms. At 7.7% of the workplaces levels of hardness of labor were assessed as harmful. The impact of such factors as biological, infrasound, ultrasound, ionizing radiation, aerosols with mainly fibrogenic action, was absent, their assessment was not carried out. Working conditions at 83.1% of workplaces were characterized as hazardous, including at 52.3% of the workplaces where there was established hazard class 3.1, at 30.7% of workplaces--Class 3.2. Among all the factors of occupational environment the largest contribution into the overall assessment of working conditions was made by the lightness factor (50.9%) and non-ionizing radiation (20.6%). The most harmful working conditions have been identified for workplaces of the operator of masthead antenna, engineer of radiocommunications, broadcasting and television, electromechanician of television (radiocommunication), (broadcasting), car driver.

    Mexican-origin parents’ work experiences are a distal extra-familial context for adolescents’ adjustment. This two-wave multi-informant study examined the prospective mechanisms linking parents’ work conditions (i.e., self-direction, work pressure, workplace discrimination) to adolescents’ adjustment (i.e., educational expectations, depressive symptoms, risky behavior) across the transition to high school drawing on work socialization and spillover models. We examined the indirect effects of parental work conditions on adolescent adjustment through parents’ psychological functioning (i.e., depressive symptoms, role overload) and aspects of the parent-adolescent relationship (i.e., parental solicitation, parent-adolescent conflict), as well as moderation by adolescent gender. Participants were 246 predominantly immigrant, Mexican-origin, two-parent families who participated in home interviews when adolescents were approximately 13 and 15 years of age. Results supported the positive impact of fathers’ occupational self-direction on all three aspects of adolescents’ adjustment through decreased father-adolescent conflict, after controlling for family socioeconomic status and earner status, and underemployment. Parental work pressure and discrimination were indirectly linked to adolescents’ adjustment, with different mechanisms emerging for mothers and fathers. Adolescents’ gender moderated the associations between fathers’ self-direction and girls’ depressive symptoms, and fathers’ experiences of discrimination and boys’ risk behavior. Results suggest that Mexican-origin mothers’ and fathers’ perceptions of work conditions have important implications for multiple domains of adolescents’ adjustment across the transition to high school.

    Full Text Available In classical conditioning, an initially neutral stimulus (conditioned stimulus, CS becomes associated with a biologically salient event (unconditioned stimulus, US, which might be pain (aversive conditioning or food (appetitive conditioning. After a few associations, the CS is able to initiate either defensive or consummatory responses, respectively. Contrary to aversive conditioning, appetitive conditioning is rarely investigated in humans, although its importance for normal and pathological behaviors (e.g., obesity, addiction is undeniable. The present study intents to translate animal findings on appetitive conditioning to humans using food as an US. Thirty-three participants were investigated between 8 am and 10 am without breakfast in order to assure that they felt hungry. During two acquisition phases, one geometrical shape (avCS+ predicted an aversive US (painful electric shock, another shape (appCS+ predicted an appetitive US (chocolate or salty pretzel according to the participants’ preference, and a third shape (CS- predicted neither US. In an extinction phase, these three shapes plus a novel shape (NEW were presented again without US delivery. Valence and arousal ratings as well as startle and skin conductance (SCR responses were collected as learning indices. We found successful aversive and appetitive conditioning. On the one hand, the avCS+ was rated as more negative and more arousing than the CS- and induced startle potentiation and enhanced SCR. On the other hand, the appCS+ was rated more positive than the CS- and induced startle attenuation and larger SCR. In summary, we successfully confirmed animal findings in (hungry humans by demonstrating appetitive learning and normal aversive learning

    Although ramjet has the advantages of high-speed flying and higher specific impulse, the performance parameters will decline seriously with the increase of flight Mach number and flight height. Therefore, the investigation on the thermodynamic performance of ramjet is very crucial for broadening the working range. In the current study, a typical ramjet model has been employed to investigate the performance characteristics at wide working conditions. First of all, the compression characteristic analysis is carried out based on the Brayton cycle. The obtained results show that the specific cross-section area (A2 and A5) and the air-fuel ratio (f) have a great influence on the ramjet performance indexes. Secondly, the thermodynamic calculation process of ramjet is given from the view of the pneumatic thermal analysis. Then, the variable trends of the ramjet performance indexes with the flow conditions, the air-fuel ratio (f), the specific cross-sectional area (A2 and A5) under the fixed operating condition, equipotential dynamic pressure condition and variable dynamic pressure condition have been discussed. Finally, the optimum value of the specific cross-sectional area (A5) and the air-fuel ratio (f) of the ramjet model at a fixed work condition (Ma=3.5, H=12 km) are obtained.

    This article presents the report of a survey on health surveillance activities performed in poultry processing plants in the south of Brazil. It aims to contribute to an understanding of the work process developed, the growth of the sector, the organization of labor and the confrontation with the economic model of this sector, which has been exposing employees to working conditions that undermine their health. The working conditions identified are considered largely incompatible with health and human dignity. The study supports interinstitutional intervention, especially with the Public Ministry of Labor, criticizes the weak implementation of specific government interventions in health conditions in the industry and introduces the new Regulatory Standard 36 as a positive perspective for the near future.

    Full Text Available As an answer to the need for reducing friction losses on bearings, dynamic seals, piston rings, cutting tools and others, a lot of work has been dedicated to mechanical systems study whose surfaces have been textured in a controlled way. Theoretical models and experimental results have shown improvements on the tribological performance of these systems regarding untextured systems, working under the same conditions. This paper presents a numerical model for getting relationships among the operational conditions (load, speed, and dynamic viscosity, the minimum lubricate film thickness, the friction coefficient and the conditioned micro-topography of a plain sliding bearing working under a hydrodynamic regime. Moreover, regarding other similar works the constructed model allows studying the combined effect of the micro-wedges that work as micro-bearings, and the typical convergent macro-wedge of these study elements.

    2016-10-01

    Translational assays of cognition that are similarly implemented in both lower and higher-order species, such as rodents and primates, provide a means to reconcile preclinical modeling of psychiatric neuropathology and clinical research. To this end, Pavlovian conditioning has provided a useful tool for investigating cognitive processes in both lab animal models and humans. This review focuses on trace conditioning, a form of Pavlovian conditioning typified by the insertion of a temporal gap (i.e., trace interval) between presentations of a conditioned stimulus (CS) and an unconditioned stimulus (US). This review aims to discuss pre-clinical and clinical work investigating the mnemonic processes recruited for trace conditioning. Much work suggests that trace conditioning involves unique neurocognitive mechanisms to facilitate formation of trace memories in contrast to standard Pavlovian conditioning. For example, the hippocampus and prefrontal cortex (PFC) appear to play critical roles in trace conditioning. Moreover, cognitive mechanistic accounts in human studies suggest that working memory and declarative memory processes are engaged to facilitate formation of trace memories. The aim of this review is to integrate cognitive and neurobiological accounts of trace conditioning from preclinical and clinical studies to examine involvement of working and declarative memory.

  7. Health, work and working conditions: a review of the European economic literature.

    2016-07-01

    Economists have traditionally been very cautious when studying the interaction between employment and health because of the two-way causal relationship between these two variables: health status influences the probability of being employed and, at the same time, working affects the health status. Because these two variables are determined simultaneously, researchers control endogeneity skews (e.g., reverse causality, omitted variables) when conducting empirical analysis. With these caveats in mind, the literature finds that a favourable work environment and high job security lead to better health conditions. Being employed with appropriate working conditions plays a protective role on physical health and psychiatric disorders. By contrast, non-employment and retirement are generally worse for mental health than employment, and overemployment has a negative effect on health. These findings stress the importance of employment and of adequate working conditions for the health of workers. In this context, it is a concern that a significant proportion of European workers (29 %) would like to work fewer hours because unwanted long hours are likely to signal a poor level of job satisfaction and inadequate working conditions, with detrimental effects on health. Thus, in Europe, labour-market policy has increasingly paid attention to job sustainability and job satisfaction. The literature clearly invites employers to take better account of the worker preferences when setting the number of hours worked. Overall, a specific "flexicurity" (combination of high employment protection, job satisfaction and active labour-market policies) is likely to have a positive effect on health.

    Long working hours adversely affect workers' safety and health. In 2004, Korea passed legislation limiting the working week to 40 h, to improve quality-of-life and to increase business competitiveness. In the present study, we explored the characteristics of work in Korea and compared our data of the second Korean Working Conditions Survey (KWCS) with those of the first KWCS. We found that the average number of hours worked weekly has been reduced but the proportions of workers who work for more than 48 h per week has increased over the 4 yr between the two Korean surveys in all categories studied (male, female, employee, self-employed, and employer). We also found that self-employed and employers work much longer hours than do employees, who are protected by the Labor Standards Act. This was particularly true in the accommodation and food service sectors. In conclusion, Korean workers work longer than do workers of EU countries. The use of average figures masks differences in the numbers of working hours among those engaged in various types of employment, or in certain work sectors. Therefore, the Korean government should not simply monitor reductions in average weekly working hours, but should identify employees working for over 60 h weekly, and reduce their working time.

    Full Text Available BACKGROUND: Cognitive complaints involving problems with concentration, memory, decision-making and thinking are relatively common in the work force. The sensitivity of both subjective and objective cognitive functioning to common psychiatric conditions, stress levels and to cognitive load makes it plausible that psychosocial working conditions play a role in cognitive complaints. Thus, this study aimed to test the associations between psychosocial work factors and cognitive complaints in nationally representative samples of the Swedish work force. Cross-sectional (n = 9751 and prospective (n = 3644; two time points two years apart sequential multiple regression analyses were run, adjusting for general confounders, depressive- and sleeping problems. Additional prospective analyses were run adjusting for baseline cognitive complaints. CROSS/SECTIONAL RESULTS: High quantitative demands, information and communication technology (ICT demands, under qualification and conflicts were positively associated with cognitive complaints, while social support, good resources at work and over qualification were negatively associated with cognitive complaints in all models. Skill discretion and decision authority were weakly associated with cognitive complaints. Conflicts were more strongly associated with cognitive complaints in women than in men, after adjustment for general confounders. PROSPECTIVE RESULTS: Quantitative job demands, ICT demands and under qualification were positively associated with future cognitive complaints in all models, including when adjusted for baseline cognitive complaints. Decision authority was weakly positively associated with future cognitive complaints, only after adjustment for depressive- and sleeping problems respectively.

    1988-01-01

    The HSE's Mine and Quarry Inspectorate initiated a review to enable them to decide whether any problems relating to hot conditions developing in mining would require legislative action. The document provides a detailed review of the effects of working in hot conditions on the workforce. It describes the underlying physiological changes which occur on exposure to heat and looks at the health implications of such changes. Hot conditions may also influence behaviour with concomitant effects on safety - the review also examines the scientific literature on these topics. Physiological changes form the basis of any monitoring procedures either through direct monitoring of the physiological status of the workforce or indirectly by using predictive equations or indices. A wide variety of these indices are described and compared within the context of the thermal conditions encountered in hot deep mining in the United Kingdom. Finally, the use of various control measures is examined from the viewpoint of their likely effect on the workforce. These measures are viewed against a background of the various legislative measures which have been adopted in some countries to minimise the risk to health and safety of individuals working in hot conditions. 230 refs., 7 figs., 4 tabs.

    Cell loss contributes to the pathogenesis of many inherited and acquired human diseases. We have developed a system to conditionally ablate cells of any lineage and developmental stage in the mouse by regulated expression of the diphtheria toxin A (DTA) gene by using tetracycline-responsive promoters. As an example of this approach, we targeted expression of DTA to the hearts of adult mice to model structural abnormalities commonly observed in human cardiomyopathies. Induction of DTA expression resulted in cell loss, fibrosis, and chamber dilatation. As in many human cardiomyopathies, transgenic mice developed spontaneous arrhythmias in vivo, and programmed electrical stimulation of isolated-perfused transgenic hearts demonstrated a strikingly high incidence of spontaneous and inducible ventricular tachycardia. Affected mice showed marked perturbations of cardiac gap junction channel expression and localization, including a subset with disorganized epicardial activation patterns as revealed by optical action potential mapping. These studies provide important insights into mechanisms of arrhythmogenesis and suggest that conditional lineage ablation may have wide applicability for studies of disease pathogenesis.

    The purpose of this study was to determine the motivation of paid non-familial caregivers of seniors, understand more about their work conditions, and identify any links to negative outcomes among their senior clients. Ninety-eight paid caregivers (eighty-five female and thirteen male), recruited from multiple sites (i.e. senior centers, shopping malls, local parks, lobbies of senior apartments, caregiver agency meetings) completed face-to-face questionnaires and semi-structured interviews. We found that 60.7% of participants chose to become a caregiver because they enjoyed being with seniors while 31.7% were unable to obtain other work, and 8.2% stated it was a prerequisite to a different health related occupation. Caregivers stated that the most challenging conditions of their work were physical lifting (24.5%), behavioral and psychological symptoms of dementia (24.5%), senior depression/mood changes (18.4%), attachment with impending death (8.2%), missing injuries to client (5.1%), lack of sleep (4.1%), and lack of connection with outside world (3.1%). Caregivers who reported that the best part of their job was the salary, flexible hours, and ease of work were significantly more likely to have clients who fell and fractured a bone than those who enjoyed being with seniors (job characteristics, 62.5% vs. senior enjoyment, 25.6%; pmotivated commonly by their love of seniors and also by their lack of other job opportunities. Paid caregivers frequently face challenging work conditions. When seeking a caregiver for a senior, motivation of the caregiver should be considered when hiring.

  15. Analysis of the Pallet Clamping Conditions in Work Positioning

    2016-01-01

    Full Text Available Pallets of automatic transfer lines serve as the technological and work-transfer equipment. However, their design is based on the general principles of designing machine accessories. Calculation of the basic design parameters of work based on their functioning features is fairly relevant.In pallet transfer movement over work positioning there is a mismatch between axes of the basic bushing of a pallet and the clamping locks of positioning. The paper identifies the factors influencing it, and defines the conditions to ensure the trouble-free clamping lock. The circular and rhombic clamping of pallet is simultaneous. Further, a clamping load is calculated from the pallet mass (together with the work-piece and the geometric parameters of the pallet clamping.The paper reveals three movement stages of the clamping lock in a vertical plane when setting the pallet in work positioning:- a clamping lock free play till it encounters with the location bushing;- a clamping lock play length when the lead-in chamfer contacts the bushing chamfer;- a clamping lock play length over the circular surface of bushing.The study of this process has allowed us to calculate the time of pallet clamping and dynamic loads acting on the clamping lock. These calculations made it possible to calculate the required diameter of the clamping lock. The presented calculations allow a reasonable assigning the main design parameters of work positioning for the pallet automatic lines.

  16. Dissociable Learning Processes Underlie Human Pain Conditioning.

    2016-01-11

    Pavlovian conditioning underlies many aspects of pain behavior, including fear and threat detection [1], escape and avoidance learning [2], and endogenous analgesia [3]. Although a central role for the amygdala is well established [4], both human and animal studies implicate other brain regions in learning, notably ventral striatum and cerebellum [5]. It remains unclear whether these regions make different contributions to a single aversive learning process or represent independent learning mechanisms that interact to generate the expression of pain-related behavior. We designed a human parallel aversive conditioning paradigm in which different Pavlovian visual cues probabilistically predicted thermal pain primarily to either the left or right arm and studied the acquisition of conditioned Pavlovian responses using combined physiological recordings and fMRI. Using computational modeling based on reinforcement learning theory, we found that conditioning involves two distinct types of learning process. First, a non-specific "preparatory" system learns aversive facial expressions and autonomic responses such as skin conductance. The associated learning signals-the learned associability and prediction error-were correlated with fMRI brain responses in amygdala-striatal regions, corresponding to the classic aversive (fear) learning circuit. Second, a specific lateralized system learns "consummatory" limb-withdrawal responses, detectable with electromyography of the arm to which pain is predicted. Its related learned associability was correlated with responses in ipsilateral cerebellar cortex, suggesting a novel computational role for the cerebellum in pain. In conclusion, our results show that the overall phenotype of conditioned pain behavior depends on two dissociable reinforcement learning circuits.

  18. Optimal working conditions for thermoelectric generators with realistic thermal coupling

    Apertet, Y; Glavatskaya, O; Goupil, C; Lecoeur, P

    2011-01-01

    We study how maximum output power can be obtained from a thermoelectric generator(TEG) with nonideal heat exchangers. We demonstrate with an analytic approach based on a force-flux formalism that the sole improvement of the intrinsic characteristics of thermoelectric modules including the enhancement of the figure of merit is of limited interest: the constraints imposed by the working conditions of the TEG must be considered on the same footing. Introducing an effective thermal conductance we derive the conditions which permit maximization of both efficiency and power production of the TEG dissipatively coupled to heat reservoirs. Thermal impedance matching must be accounted for as well as electrical impedance matching in order to maximize the output power. Our calculations also show that the thermal impedance does not only depend on the thermal conductivity at zero electrical current: it also depends on the TEG figure of merit. Our analysis thus yields both electrical and thermal conditions permitting optima...

    2000-01-01

    Many studies on the impact of psychosocial working conditions on health prove that psychosocial stress at work is an important risk factor endangering workers' health. Thus it should be constantly monitored like other work hazards. The paper presents a newly developed instrument for stress monitoring called the Psychosocial Working Conditions Questionnaire (PWC). Its structure is based on Robert Karasek's model of job stress (Karasek, 1979; Karasek & Theorell, 1990). It consists of 3 main scales Job Demands, Job Control, Social Support and 2 additional scales adapted from the Occupational Stress Questionnaire (Elo, Leppanen, Lindstrom, & Ropponen, 1992), Well-Being and Desired Changes. The study of 8 occupational groups (bank and insurance specialists, middle medical personnel, construction workers, shop assistants, government and self-government administration officers, computer scientists, public transport drivers, teachers, N = 3,669) indicates that PWC has satisfactory psychometrics parameters. Norms for the 8 groups were developed.

    2006-01-01

    Full Text Available A general problem of this research is to identify if there is a relationship between the assumption on human nature and work (Mcgregor, Argyris, Schein, Steers and Porter and a general organizational model preference, as well as a mechanism of human resource management? This research was carried out in 2005/2006. The sample consisted of 317 subjects (197 managers, 105 highly educated subordinates and 15 entrepreneurs in 7 big enterprises in a group of small business enterprises differentiating in terms of the entrepreneur’s structure and a type of activity. A general hypothesis "that assumptions on human nature and work are statistically significant in connection to the preference approach (models, of work motivation commitment", has been confirmed. A specific hypothesis have been also confirmed: ·The assumptions on a human as a rational economic being are statistically significant in correlation with only two mechanisms of traditional models, the mechanism of method work control and the working discipline mechanism. ·Statistically significant assumptions on a human as a social being are correlated with all mechanisms of engaging employees, which belong to the model of the human relations, except the mechanism introducing the adequate type of prizes for all employees independently of working results. ·The assumptions on a human as a creative being are statistically significant, positively correlating with preference of two mechanisms belonging to the human resource model by investing into education and training and making conditions for the application of knowledge and skills. The young with assumptions on a human as a creative being prefer much broader repertoire of mechanisms belonging to the human resources model from the remaining category of subjects in the pattern. The connection between the assumption on human nature and preference models of engaging appears especially in the sub-pattern of managers, in the category of young subjects

  4. [Shift Work among Men and Women on the Threshold to Higher Working Age - Working Conditions and Health Status].

    Science.gov (United States)

    Leser, C; Tisch, A; Tophoven, S

    2016-11-01

    Background: The number of older employees in shift and night work has increased significantly in recent years. Furthermore, the proportion of women in shift and night work has increased markedly. This is due to the aging workforce and the expansion of shift work in the tertiary sector. Previous research shows that shift work is often associated with health risks. Against this background, the aim of the present study is to examine the situation of working men and women on the threshold to higher working age with regard to the relationship between shift work and physical health. Methods: We employed data from the study "lidA - leben in der Arbeit" German Cohort Study on Work, Age and Health, a survey of the German baby boom cohorts born in 1959 and 1965 (n=5 637). Linear regression models are used to study the effect of shift work - with and without night work - and of further work exposures on the baby boomers' physical health status. The models control for sleep and health-related behaviour and are stratified by gender. Among women, also the scope of work was taken into account. Results: The results show that male shift workers are burdened by their on average lower occupational status and by physical exposure; female shift workers additionally suffer from high personal effort and low rewards and female part-time shift workers also from overcommitment. Conclusion: Working conditions of shift workers are strongly characterised by work stress. In order to preserve aging shift workers' work ability, some organisational measures seem necessary. In this context, occupational safety and health management as well as opportunities for recovery and encouraging leadership should be considered.

    2000-01-01

    After the long shutdown (December 2000 to May 2001), the SPS complex will work with the main water-cooling loop in closed circuit. This will affect the working conditions because of the higher temperature of the supplied water (24 ° C, i.e. 15 K higher) and therefore of the air in the tunnel. The cooling installations will consequently be upgraded or replaced to meet the new needs, and several new chilled-water stations will be installed to supply the present users. The author will thoroughly explain the main aspects of all these modifications and report the results of the preliminary tests carried out in September 1996. Finally, an overview of the global costs (operational and linked to the project) will be given, taking into account the different consumption of water, electricity and the effects on the magnet components.

    In order to evaluate on-line corrosive electrolyte concentration in solar air conditioning systems, an optical technique to determine the concentration is being proposed. With this optical sensing method, it is possible to measure the percentage concentration of the aqueous corrosive lithium bromide solution at temperatures ranging from 25{sup o}C to 70{sup o}C and a maximum concentration of 60%. The measurement system is based on the refractive index of the solution and the data correlation, at several temperature and concentration values. The results of this work present a direct method for concentration measurement of corrosive liquids and also show the correlation among the three parameters: refractive index, temperature and weight concentration. This correlation can be used to develop the optical device for solar air conditioning systems to control and improve efficiency. (author)

    Nowadays, no studies have been published on the relationship between meteorological conditions and work-related mortality and morbidity in Italy. The aim of this study was to evaluate the relationship between hot weather conditions and hospital admissions due to work-related accidents in Tuscany (central Italy) over the period 1998-2003. Apparent temperature (AT) values were calculated to evaluate human weather discomfort due to hot conditions and then tested for work accident differences using non-parametric procedures. Present findings showed that hot weather conditions might represent a risk factor for work-related accidents in Italy during summer. In particular early warming days during June, characterized by heat discomfort, are less tolerated by workers than warming days of the following summer months. The peak of work-related accidents occurred on days characterized by high, but not extreme, thermal conditions. Workers maybe change their behaviour when heat stress increases, reducing risks by adopting preventive measures. Results suggested that days with an average daytime AT value ranged between 24.8 degrees C and 27.5 degrees C were at the highest risk of work-related accidents. In conclusion, present findings might represent the first step for the development of a watch/warning system for workers that might be used by employers for planning work activities.

  11. Bad Jobs, Bad Health? How Work and Working Conditions Contribute to Health Disparities.

    Science.gov (United States)

    Burgard, Sarah A; Lin, Katherine Y

    2013-08-01

    In this review, we touch on a broad array of ways that work is linked to health and health disparities for individuals and societies. First focusing on the health of individuals, we discuss the health differences between those who do and do not work for pay, and review key positive and negative exposures that can generate health disparities among the employed. These include both psychosocial factors like the benefits of a high status job or the burden of perceived job insecurity, as well as physical exposures to dangerous working conditions like asbestos or rotating shift work. We also provide a discussion of the ways differential exposure to these aspects of work contributes to social disparities in health within and across generations. Analytic complexities in assessing the link between work and health for individuals, such as health selection, are also discussed. We then touch on several contextual level associations between work and the health of populations, discussing the importance of the occupational structure in a given society, the policy environment that prevails there, and the oscillations of the macroeconomy for generating societal disparities in health. We close with a discussion of four areas and associated recommendations that draw on this corpus of knowledge but would push the research on work, health and inequality toward even greater scholarly and policy relevance.

    The purpose of this study was to determine the personal factors and working conditions that predict work injuries among industrial workers. To fulfill this aim, a case control study was conducted including 2003 industrial workers who sustained a work injury and an equal number of controls. All were subjected to an interview questionnaire to collect relevant information. Moreover, records were reviewed to obtain the medical history of enrolled workers. Data revealed that workers in the index and control groups are comparable in respect to their sociodemographic characteristics. The multivariate logistic regression analysis pointed out that safety training significantly reduces the risk of work accidents among industrial workers. On the other hand, work accidents are more likely to occur in the main working shift. Moreover, workers who suffer from chronic health problems calling for surgical treatment, as well as those who reported family problems, are more likely to experience work accidents. These workers should receive considerable attention to reduce the extent of work injuries. More importantly, safety-training programs are mandatory for accident prevention in industrial settings.

    2010-01-01

    The Italian Constitution (1948) defines 'work' as the founding value of the Italian Republic. This choice was not motivated by mere economic reasons, but rather stemmed from the recognition that work is the most appropriate tool for the expression of the human personality in society, that it is an asset and a right that will increase the dignity of every person, and which corresponds to a fundamental human desire to fulfil oneself in relationship with other persons and the entire world This view of work, including its technical and manual aspects, was unknown to the ancient mentality and became familiar to us through the monastic orders of the early middle ages, which began to conceive and practise human work as a means of participating in the work of creation and transmitted this value over the centuries. As we experience today, if occupation is lacking, a basic condition for the development of the person and for his/her contribution to the growth of society is lost. Given the meaning of work in human experience, it is not surprising that unemployment represents not only a worrisome economic indicator, but also the cause of ill health. At the end of 2009 unemployment in the European Union reached 10%, similar to the rate in the US; in Italy it was estimated at 8.5% in December 2009 and is expected to reach 10% in 2010. In Lombardy, although employment had been constantly increasing between 1995 and 2008, and the current unemployment rate is as low as 4.9%, 100,000 jobs were lost in 2009. Several scientific papers have demonstrated the association between lack of occupation and lack of physical and mental health. In the present period of crisis, increases of 30% in cases of anxiety syndrome and of 15% in cases of depression have been reported. An increase in suicides among unemployed persons has been documented in several countries even if there are still problems of interpretation of the causal chain of events. Mortality among the unemployed increased, not only

    Europe-wide efforts are being initiated to define quality standards and harmonize Otolaryngology, Head and Neck Surgery (ORL-HNS)-specialty-training by creating an European board examination. However, differences within and between countries remain and are underinvestigated making comparisons and further improvement more difficult. The study aimed at assessing quality of training, satisfaction and quality of life of residents and recent ORL-HNS specialists in Spain and to trace similarities and differences to France and Germany administering anonymous online-questionnaire to ORL-HNS-residents and recent specialists. 146 questionnaires were returned with answers of 75.6 % of residents, a mean age of 30 years and a female to male ratio of 1.46:1. The global satisfaction of training was high as 76 % would choose the same ENT training again, 86 % confirmed that responsibilities which were given to them were adapted to their level of training and 97 % felt well considered in their department. Ninety-two confirmed that helpful seniors contributed to a good work environment (75 %) and to a good organization within the department (69 %). The respondents spent on average 8.8 h per day at the hospital and covered on average 4.8 night duties or week-end shifts per month with mostly no post-day off (86 %). Seventy-four percent participated regularly at complementary training sessions. Research work was supported and guided in 59 %. This study is the first one, to our best of knowledge, to assess the ORL-HNS-training in Spain and to trace parallelisms and differences to other European countries, such as France and Germany. The satisfaction of training and supervision was high in Spain, but there are still efforts to make concerning resident's quality of life. Compared to France and Germany, satisfaction with ORL-HNS-training and the support and guidance provided by seniors was similar. Work conditions were comparable to those in France.

    2014-09-01

    Full Text Available Human sexuality is of vital importance to social work practitioners, educators, and scholars. Yet historically, the profession’s leadership around it has waxed and waned, impacting practice. This article discusses the importance of human sexuality as a critical subfield within social work. It suggests that the mechanisms, namely textbooks, journals, and national conferences, for stimulating human sexuality social work scholarship are limited. The authors assert that the taboo of human sexuality limits the advancement of a cohesive professional discourse and contributes to the continued oppression of marginalized populations. Recommendations for providing better support for those who study, teach, and practice in the arena of human sexuality are offered.

    Full Text Available Abstract Background The focus on the determinants of the quality of health services in low-income countries is increasing. Health workers' motivation has emerged as a topic of substantial interest in this context. The main objective of this article is to explore health workers' experience of working conditions, linked to motivation to work. Working conditions have been pointed out as a key factor in ensuring a motivated and well performing staff. The empirical focus is on rural public health services in Tanzania. The study aims to situate the results in a broader historical context in order to enhance our understanding of the health worker discourse on working conditions. Methods The study has a qualitative study design to elicit detailed information on health workers' experience of their working conditions. The data comprise focus group discussions (FGDs and in-depth interviews (IDIs with administrators, clinicians and nursing staff in the public health services in a rural district in Tanzania. The study has an ethnographic backdrop based on earlier long-term fieldwork in the same part of Tanzania. Results The article provides insights into health workers' understanding and assessment of their working conditions. An experience of unsatisfactory working conditions as well as a perceived lack of fundamental fairness dominated the FGDs and IDIs. Informants reported unfairness with reference to factors such as salary, promotion, recognition of work experience, allocation of allowances and access to training as well as to human resource management. The study also revealed that many health workers lack information or knowledge about factors that influence their working conditions. Conclusions The article calls for attention to the importance of locating the discourse of unfairness related to working conditions in a broader historical/political context. Tanzanian history has been characterised by an ambiguous and shifting landscape of state regulation

    Heart Rate Variability, HRV, studies the variations of cardiac rhythm caused by the autonomic regulation. HRV analysis can be applied to the study of the effects of mental or physical stressors on the psychophysiological conditions. The present work is a pilot study performed on a 23-year-old healthy subject. The measurement of HRV was performed by means of two sensors, that is an electrocardiograph and a Laser Doppler Vibrometer, which is a non-contact device able to detect the skin vibrations related to the cardiac activity. The present study aims to evaluate the effects of a physical task on HRV parameters (in both time and frequency domain), and consequently on the autonomic regulation, and the capability of Laser Doppler Vibrometry in correctly detecting the effects of stress on the Heart Variability. The results show a significant reduction of HRV parameters caused by the execution of the physical task (i.e. variations of 25-40% for parameters in time domain, also higher in frequency domain); this is consistent with the fact that stress causes a reduced capability of the organism in varying the Heart Rate (and, consequently, a limited HRV). LDV was able to correctly detect this phenomenon in the time domain, while the parameters in the frequency domain show significant deviations with respect to the gold standard technique (i.e. ECG). This may be due to the movement artefacts that have consistently modified the shape of the vibration signal measured by means of LDV, after having performed the physical task. In the future, in order to avoid this drawback, the LDV technique could be used to evaluate the effects of a mental task on HRV signals (i.e. the evaluation of mental stress).

    Nursing--a human service increasing in size and significance--is facing deep changes. The organization of hospital wards is also influenced by these profound changes. The aim of this psychological research project sponsored by the German Federal Ministry for Education and Science, Research and Technology (BMBF) and part of the Saxonian Public Health Association was to determine the external and individual working conditions that put the personnel's health at risk, particularly in regard to burnout syndromes. Investigations should show possibilities in work organization that minimize such risks. Organizational designs have to ensure high quality levels of nursing care, as well as high quality of working conditions in nursing for the individual employee. This empirical study presents the results of an investigation of 53 medical, surgical and intensive care units of 7 Saxonian hospitals with 336 employees of the nursing departments. The size of the hospital, the service profile, the nursing standards and the organizational conditions of the nursing service influence work pressure and working attitude.

    de Carvalho, Carlos R.

    2016-07-01

    In this article we address the assumptions concerning the equilibrium of rigid bodies, commonly used in textbooks, that can lead to completely wrong conclusions. In particular, we show that in an idealised world, where frictions and deformations don’t occur, a steelyard or two-pan balance would not work. This apparent contradiction, that one needs imperfections to make things work, doesn’t appear in textbooks because the corresponding topics are presented in the equilibrium configuration, where the imperfections’ role is no longer necessary. At the end, taking the two-pan balance as example, we show that to avoid of working with imperfections, one must deal with a device whose design has a subtle difference from that one we are used to think about.

  19. Towards a Human Rights Culture in Social Work Education.

    Science.gov (United States)

    Werkmeister Rozas, Lisa; Garran, Ann Marie

    2016-06-01

    A human rights perspective must be embedded in the institutions, organisations or agencies where social work students find themselves. This paper will focus on one particular strategy that could be helpful to the process of solidifying a commitment to human rights for our students. Using a pedagogical tool from a school of social work in the USA originally developed to combat the social injustice of racism, the example transcends the academic institution and offers a solid link in connecting human rights, social justice and social work. Using the construct of critical realism, we argue that, for social work programmes to take steps towards an explicit commitment to human rights, not only must human rights be infused throughout the curriculum, but educators must provide opportunities for making more overt the links between human rights principles, social justice and social work. By addressing behaviours, tendencies and attitudes, students then acquire not only the skills and deeper understanding, but they internalise the motivation and commitment to broaden their human rights frame. In the process of developing a more firm commitment to human rights, we must not be limited to the walls of the academy, but rather extend beyond to our field agencies, organisations and communities.

It formed a rather paradoxical situation, because definition of aesthetics is always a part of it, such as art and – simultaneously – the issue is no science that reveals the essence of the person who creates the art. The purpose of this article is to study empathy as a special manifestation of human sensibility in the process flow of the creative act that reveals the essence of the artist's creative activity, developed sensuality is transformed into a work of art. Methodological and theoretical basis of the study was a combination of systemic, structural-functional and hermeneutic approaches; psychological and philosophical concepts of empathy problems and theoretical analysis of foreign and domestic literature in the field of philosophy, aesthetics, psychology. The scientific novelty of the research results is determined by the subject of study. The problem of art itself is in the field of modern aesthetic science, but in the context of its consideration of empathy reveals new theoretical aspects that deepen the level of processing and correcting the problem. Conclusions. Empathy, being a particular manifestation of human sensibility, is a necessary condition for creativity. After analyzing the nature of human creativity we came to the conclusion that the basis of the embodiment of sensibility of the artist in a work of art is a process of empathy. It is noted that the method of empathy is one of heuristic methods of creative activity, which is based on a process of empathy, i.e. identification of the object and the subject of creativity, "use", and creator inherent in any field of activity and is widely used in solving problems of art.

    2014-07-01

    We investigated the prevalence of reduced demand-specific work ability, its association with age, gender, education, poor health, and working conditions, and the interaction between poor health and working conditions regarding reduced demand-specific work ability. We used cross-sectional questionnaire data from 3381 full-time employees responding to questions about vocational education, job demands and social support (working conditions), musculoskeletal pain (MSP) and major depression (MD) (poor health) and seven questions about difficulty managing different job demands (reduced demand-specific work ability). Reduced demand-specific work ability varied from 9% to 19% among the 46-year old and from 11% to 21% among the 56-year old. Age was associated with two, gender with four, and education with all measures of reduced demand-specific work ability. MSP was associated with four and MD was associated with six measures of reduced demand-specific work ability. We found no interaction between working conditions and poor health regarding reduced demand-specific work ability.

    2014-01-01

    This article is the first to examine the association between self-reported general health and a wide range of working conditions at the European level and by type of welfare state regime. Data for 21,705 men and women ages 16 to 60 from 27 European countries were obtained from the 2010 European Working Conditions Survey. The influence of individual-level sociodemographic, physical, and psychosocial working conditions and of the organization of work were assessed in multilevel logistic regression analyses, with additional stratification by welfare state regime type (Anglo-Saxon, Bismarckian, Eastern European, Scandinavian, and Southern). At the European level, we found that "not good" general health was more likely to be reported by workers more exposed to hazardous working conditions. Most notably, tiring working positions, job strain, and temporary job contracts were strongly associated with a higher likelihood of reporting "not good" health. Analysis by welfare state regime found that only tiring or painful working conditions were consistently associated with worse self-reported health in all regimes. There was no evidence that the Scandinavian welfare regime protected against the adverse health effects of poor working conditions. The article concludes by examining the implications for comparative occupational health research.

    2012-01-01

    This paper presents the model "Work Situation Operative Model" - MOST (after its Spanish acronym). It offers a comprehensive, systemic approach to analysing work stations and/or work processes, serving also as a framework for pursuing various ergonomic and occupational health and safety goals. Originally produced for a food sector company, the model has been extended and successfully applied in several industries in Colombia and Ecuador, including cement, oil, and paper industries. Based on a systemic understanding of work systems and tasks, the model not only allows different, commonly-used methods and tools for evaluating or assessing the risk of muscular-sketetal disorders to be included, but also supports occupational risk management strategies. Hence, one of its more important contributions relies on providing meaningful information that is useful for improving the work station and/or work process through design and re-design, by focusing on the interactions between all system elements.

    2005-04-01

    The nose is the front line defender of the respiratory system. Unsteady simulations in three-dimensional models have been developed to study transport patterns in the human nose and its overall air-conditioning capacity. The results suggested that the healthy nose can efficiently provide about 90% of the heat and the water fluxes required to condition the ambient inspired air to near alveolar conditions in a variety of environmental conditions and independent of variations in internal structural components. The anatomical replica of the human nose showed the best performance and was able to provide 92% of the heating and 96% of the moisture needed to condition the inspired air to alveolar conditions. A detailed analysis explored the relative contribution of endonasal structural components to the air-conditioning process. During a moderate breathing effort, about 11% reduction in the efficacy of nasal air-conditioning capacity was observed.

    Full Text Available The paper analyzes the significance and peculiarities of corporate culture formation for remote employees. Particular attention is paid to instruments that allow creating a team in the absence of the usual office environment. There have been defined the signs of trust manifestation that distinguish the corporate culture in a team with experience of teamwork and without such experience — a level of weakness manifestation and recognition of mistakes, presence of critics from colleagues, asking for recourse, interest in colleagues’ experience and skills. According to the signs the necessary management practices for the development and creation of the corporate culture has been offered. It is noted that the team with the experience of teamwork at the early stages acts quite consistently adhering to the declared standards, rules and basic values. However, even under these conditions, the corporate culture is growing weaker in time. And here it would be helpful to use the management practices that do not replace personal contact but are maximally close to it. All management practices are classified in accordance with the directions of the corporate culture development, namely, creation of effective social intranet, establishment of quality communication, transparent motivation and clear description of the control sequences, description and establishment of clear guidelines, development of personal effectiveness of employees, simplification of the project communication process, creation of “virtual coolers”, the philosophy of “getting into the body” of a remote employee, monitoring professional burnout, etc.

    Healthy humans normally breathe through their nose even though its complex geometry imposes a significantly higher resistance in comparison with mouth breathing. The major functional roles of nasal breathing are defense against infiltrating particles and conditioning of the inspired air to nearly alveolar conditions in order to maintain the internal milieu of the lung. The state-of-the-art of the existing knowledge on nasal air-conditioning will be discussed in this review, including in vivo measurements in humans and computational studies on nasal air-conditioning capacity. Areas where further studies will improve our understanding and may help medical diagnosis and intervention in pathological states will be introduced.

    The differences in using a "social isolation" concept in the psychological literature are presented. The term of "relative social isolation" is clarified. A relationship between human adaptation to the relative social isolation environments and the development of his social qualities and social activities is presented. The "social context", dictating motivation attitudes of a man to the isolation situation, emotional experiences, self-appraisal of activity is of crucial importance for evaluating the real environments of relative social isolations. Social activity of a personality is studied as the relations of a man with the conditions of his activity. The results of studying the dynamics of the psychic state of a man during individual and group isolation are compared. It is concluded that social activity of man and his functional state are interrelated. The particular manifestations and direction of the changes in the social activity of the subject depend on the duration of isolation and are determined first of all by social significance and meaningful and balanced work for a person as well as by the amount and frequency of direct and mediated social contacts under specific conditions of relative social isolation.

    Full Text Available Managing health and safety at work involves considering two internal processes common to all organizations: knowledge and human talent management. These two processes are affected by globalizing phenomena that have an effect at the economic, environmental, and occupational levels. This is especially true for countries like Colombia. Objective: to provide an educational alternative that contributes to knowledge management in SME’s in order to improve the working conditions and to support their innovation processes. Methodology: an exploratory and descriptive study. We start by analyzing the concepts related to the improvement of working conditions and experiences from previous projects involving the university-industry relationship. This is done from the systemic viewpoint that characterizes the ergonomics and interdisciplinary perspectives of the professional practice of industrial design. Result: the proposal was approved by regional institutions wishing to conduct a pilot study, and is based on principles establishing health promotion at the workplace. It also includes a methodology for affecting the technological core of companies and contributes to the empowerment of the personnel involved. Conclusion:it is mandatory that organizations express their support and commitment through a policy that facilitates the active participation of employees in these processes.

  2. Ergonomic strategies for improving working conditions in some developing countries in Asia.

    1999-04-01

    Ergonomic action is growing in Asia in response to increasing local needs. Recent studies in some developing countries in Asia commonly developed and applied widely-applicable measures for assessing local needs in field conditions including small enterprises and agriculture. For this purpose, carefully examining the actual workplace conditions of the local people was essential. Consequently, a number of field studies could contributed to improving the working conditions of the local people in materials handling, workstation design, work organization and work environment by using available local resources. Building on local capacity and practice, action-oriented ergonomics training has also been developing and spreading into many workplaces. Various non-expert human resources including local government units, trade unions, industrial associations and the agricultural sectors have been mobilized to act as participatory trainers in the action-oriented ergonomic training programmes. Training tools such as action checklists, good local examples and group work dynamics have been developed and applied to such training activities. Learning from local achievements and focusing on locally available resources, ergonomists have facilitated these local action processes by developing action-oriented training tools and training local trainers. It was confirmed that a number of ergonomic improvements could be formulated by the self-help initiative of the local people when participatory action tools and training were provided. Developing flexible and dynamic ergonomic research and training methods to meet the diversifying needs of the local people will continuously be important. Ergonomists' efforts to cover the wider population and workplaces need to be strengthened and accelerated.

    2010-09-01

    This study aimed to examine how physical working conditions, psychosocial working conditions and work-family conflicts are associated with sleep complaints, and whether health behaviours explain these associations. We used pooled postal questionnaire surveys collected in 2001-2002 among 40-60-year-old employees of the City of Helsinki (n = 5819, response rate 66%). Participants were classified as having sleep complaints if they reported sleep complaints at least once a week on average (24% of women and 20% of men). Independent variables included environmental work exposures, physical workload, computer work, Karasek's job strain and work-family conflicts. Age, marital status, occupational class, work arrangements, health behaviours and obesity were adjusted for. Most working conditions were associated strongly with sleep complaints after adjustment for age only. After adjustment for work-family conflicts, the associations somewhat attenuated. Work-family conflicts were also associated strongly with women's [odds ratio (OR) 5.90; confidence interval (CI) 4.16-8.38] and men's sleep (OR 2.56; CI 1.34-4.87). The associations remained robust even after controlling for unhealthy behaviours, obesity, health status, depression and medications. Physically strenuous working conditions, psychosocial job strain and work-family conflicts may increase sleep complaints. Efforts to support employees to cope with psychosocial stress and reach a better balance between paid work and family life might reduce sleep complaints. Sleep complaints need to be taken into account in worksite health promotion and occupational health care in order to reduce the burden of poor sleep.

    Science.gov (United States)

    Sissom, Matthew

    reinforces the concept that the human desire to define existence begins at the subatomic level. In terms of my own writing, the focus turns to the origin of change. What is change? What brings it about? When I wrote "Of Higgs and Flame," the physics world was still riding the waves of CERN's Higgs boson particle discovery. Admittedly, the story contains a not-so-researched passage in which Darren contemplates the surge of change coursing from within, but this was done intentionally. Darren represents my approach to physics, which is mostly relegated to a spectator role, in that he is trying to define the occurring change based on his incomplete, loose understanding of Higgs boson and other scientific concepts. The analysis of my writing and that of Whitman reflects Stephen Hawking's explanation in A Briefer History of Time regarding the possibilities of a true, unifying theory of physics. He poses that there may exist an infinite sequence of theories that may get closer and closer to accurately describing the universe but are never exact (134). This is what I try to do with my work. I do not write under the pretense that I will be able to precisely replicate, in epiphany-like fashion, the human condition, accurately wrangling all of the variables that influence our reasons for changing or acting within a given scenario or conflict. Instead, I hope that my use of the same curiosity that fuels my passion to both read about physics and write fiction presents a more accurate understanding of the human condition, offering up characters whose changes within each story forces the audience to, at least momentarily, linger on that existential Why?.

    The objective of this study was to examine the associations of working conditions with major weight gain. Three different groups of work-related factors were examined: (i) work arrangements, (ii) physical working conditions, and (iii) psychosocial working conditions. The data are based on the Helsinki Health Study (HHS) questionnaire surveys. A baseline mail survey was made among middle-aged employees of the City of Helsinki in 2000-2002. A follow-up survey was made in 2007. Regression analyses with odds ratios and 95% confidence intervals were calculated. During the 5- to 7-year follow-up, 26% of women and 24% of men gained in weight 5 kg or more. Working conditions were mostly unassociated with weight gain. However, nighttime shift work, physical threat at work, and hazardous exposures at work were moderately associated with weight gain. More attention should be devoted to the prevention of weight gain in general and among risk groups in particular.

    Despite a wealth of knowledge on how humans and nonhuman animals learn to associate meaningful events with cues in the environment, far less is known about how humans learn to associate these events with the environment itself. Progress on understanding spatiotemporal contextual processes in humans has been slow in large measure by the methodological constraint of generating and manipulating immersive spatial environments in well-controlled laboratory settings. Fortunately, immersive Virtual Reality (iVR) technology has improved appreciably and affords a relatively straightforward methodology to investigate the role of context on learning, memory, and emotion while maintaining experimental control. Here, we review context conditioning literature in humans and describe challenges to study contextual learning in humans. We then provide details for a novel context threat (fear) conditioning paradigm in humans using a commercially available VR headset and a cross-platform game engine. This paradigm resulted in the acquisition of subjective threat, threat-conditioned defensive responses, and explicit threat memory. We make the paradigm publicly available and describe obstacles and solutions to optimize future studies of context conditioning using iVR. As computer technology advances to replicate the sensation of realistic environments, there are increasing opportunities to bridge the translational gap between rodent and human research on how context modulates cognition, which may ultimately lead to more optimal treatment strategies for anxiety- and stress-related disorders.

    Retention of nursing staff remains an important issue for health care managers. Turnover research has focused primarily on motivational and social factors as keys to retention, whereas the role of the physical work conditions has received considerably less attention. However, work design theory suggests that physical work conditions may be an important factor in fostering retention among nursing staff. The aim of this study was to integrate work design theory with turnover process models to explore the influence of perceptions of physical work conditions on the development of turnover intentions among nursing staff. Drawing on two samples of registered nurses working in cancer units in metropolitan hospitals in the southeastern United States, this study explores the impact of perceptions of physical work conditions on turnover intentions using ordinary least squares regression. Hypotheses are tested in Study 1 and replicated in Study 2. A measure of perceptions of physical work conditions is also developed and validated using exploratory (Study 1) and confirmatory (Study 2) factor analyses. Perceptions of physical work conditions explain variance in turnover intentions above than that explained by motivational and social factors. Specifically, employee perceptions of noisy work conditions are found to significantly increase turnover intentions, whereas perceptions that work conditions facilitate tasks were found to significantly reduce turnover intentions. Perceptions of temperature and health hazard did not show significant effects. Results suggest that health care managers and scholars should re-examine the role of physical work conditions in the turnover process. Investments in upgrades that facilitate tasks may foster retention better than investments that simply improve employee comfort. Negative perceptions of work conditions may have no impact if they are considered a normal "part of the job," although negative perceptions of conditions that are viewed as

    2010-05-01

    This study considers the complex dynamics of work motivation. Forty-eight employees completed a work-motivation diary several times per day over a period of four weeks. The obtained time series were analysed using different methodologies derived from chaos theory (i.e. recurrence plots, Lyapunov exponents, correlation dimension and surrogate data). Results showed chaotic dynamics in 75% of cases. The findings confirm the universality of chaotic behavior within human behavior, challenge some of the underlying assumptions on which work motivation theories are based, and suggest that chaos theory may offer useful and relevant information on how this process is managed within organizations.

    Primates can store sensory stimulus parameters in working memory for subsequent manipulation, but until now, there has been no demonstration of this capacity in rodents. Here we report tactile working memory in rats. Each stimulus is a vibration, generated as a series of velocity values sampled from a normal distribution. To perform the task, the rat positions its whiskers to receive two such stimuli, "base" and "comparison," separated by a variable delay. It then judges which stimulus had greater velocity SD. In analogous experiments, humans compare two vibratory stimuli on the fingertip. We demonstrate that the ability of rats to hold base stimulus information (for up to 8 s) and their acuity in assessing stimulus differences overlap the performance demonstrated by humans. This experiment highlights the ability of rats to perceive the statistical structure of vibrations and reveals their previously unknown capacity to store sensory information in working memory.

    Full Text Available This is an exploratory and descriptive study with a quantitative approach that aimed to understand the social production and reproduction processes of women working at university restaurants and the occurrence and the magnitude of gender-based violence committed against them by their intimate partners. The data were collected through semi-structured interviews. The analysis categories used were social production and reproduction, gender and gender-based violence. The interviewees held a subordinate social position during the productive and reproductive periods of their lives. Approximately 70% reported having experienced gender-based violence from an intimate partner (66% psychological violence, 36.3% physical violence and 28.6% sexual violence. Most of the health problems resulting from violence were related to mental health. The results indicate that the situation requires immediate interventions, mostly guided by the instrumentalization of these women and the support by the state and the university as appropriate to address violence.

    Cognitive functions, such as working memory, depend on neuronal excitability in a distributed network of cortical regions. It is not known, however, if interindividual differences in cortical excitability are related to differences in working memory performance. In the present transcranial magnetic stimulation study, which included 188 healthy young subjects, we show that participants with lower resting motor threshold, which is related to higher corticospinal excitability, had increased 2-back working memory performance. The findings may help to better understand the link between cortical excitability and cognitive functions and may also have important clinical implications with regard to conditions of altered cortical excitability.

    The industrial revolution demonstrated the limitations of a pure mechanistic approach towards work design. Human work is now seen as a complex entity that involves different scientific branches and blurs the line between mental and physical activities. Job design has been a traditional concern of applied psychology, which has provided insight into the interaction between the individual and the work environment. The goal of this paper is to introduce the human-at-work system as a holistic approach to organizational design. It postulates that the well-being of workers and work outcomes are issues that need to be addressed jointly, moving beyond traditional concepts of job satisfaction and work stress. The work compatibility model (WCM) is introduced as an engineering approach that seeks to integrate previous constructs of job and organizational design. The WCM seeks a balance between energy expenditure and replenishment. The implementation of the WCM in industrial settings is described within the context of the Work Compatibility Improvement Framework. A sample review of six models (motivation-hygiene theory; job characteristics theory; person-environment fit; demand-control model; and balance theory) provides the foundation for the interaction between the individual and the work environment. A review of three workload assessment methods (position analysis questionnaire, job task analysis and NASA task load index) gives an example of the foundation for the taxonomy of work environment domains. Previous models have sought to identify a balance state for the human-at-work system. They differentiated between the objective and subjective effects of the environment and the worker. An imbalance between the person and the environment has been proven to increase health risks. The WCM works with a taxonomy of 12 work domains classified in terms of the direct (acting) or indirect (experienced) effect on the worker. In terms of measurement, two quantitative methods are proposed

  8. The involvement of the human cerebellum in eyeblink conditioning.

    Besides its known importance for motor coordination, the cerebellum plays a major role in associative learning. The form of cerebellum-dependent associative learning, which has been examined in greatest detail, is classical conditioning of eyeblink responses. The much advanced knowledge of anatomical correlates, as well as cellular and molecular mechanisms involved in eyeblink conditioning in animal models are of particular importance because there is general acceptance that findings in humans parallel the animal data. The aim of the present review is to give an update of findings in humans. Emphasis is put on human lesion studies, which take advantage of the advances of high-resolution structural magnetic resonance imaging (MRI). In addition, findings of functional brain imaging in healthy human subjects are reviewed. The former helped to localize areas involved in eyeblink conditioning within the cerebellum, the latter was in particular helpful in delineating extracerebellar neural substrates, which may contribute to eyeblink conditioning. Human lesion studies support the importance of cortical areas of the ipsilateral superior cerebellum both in the acquisition and timing of conditioned eyeblink responses (CR). Furthermore, the ipsilateral cerebellar cortex seems to be also important in extinction of CRs. Cortical areas, which are important for CR acquisition, overlap with areas related to the control of the unconditioned eyeblink response. Likewise, cortical lesions are followed by increased amplitudes of unconditioned eyeblinks. These findings are in good accordance with the animal literature. Knowledge about contributions of the cerebellar nuclei in humans, however, is sparse. Due to methodological limitations both of human lesion and functional MRI studies, at present no clear conclusions can be drawn on the relative contributions of the cerebellar cortex and nuclei.

    Nursing staff in nursing homes suffer from poor mental health, probably associated with stressful working conditions. Working conditions may distribute differently among nursing assistants, licensed practical nurses, and registered nurses due to their different levels in the organizational hierarchy. The objectives of this study were to evaluate the association between working conditions and mental health among different nursing groups, and examine the potential moderating effect of job group on this association. Self-administered questionnaires were collected with 1,129 nursing staff in 15 for-profit non-unionized nursing homes. Working conditions included both physical and psychosocial domains. Multivariate linear regression modeling found that mental health was associated with different working conditions in different nursing groups: physical safety (β = 2.37, p work-family conflict (β = -2.44, p work-family conflict (β = -4.17, p working conditions and mental health. Future workplace interventions to improve mental health should reach to nursing staff at different levels and consider tailored working condition interventions in different nursing groups.

    The mental health of educators is a growing problem in many countries. This study sought to identify self-reported stressful working conditions of elementary schoolteachers and the biopsychosocial consequences of those working conditions and then identify working conditions that promote well-being for teachers in the workplace. Exploratory study was done with 37 teachers. Data collection was performed using a structured interview with a questionnaire. Results show that stressful working conditions are related to inadequate salary, an excessive number of activities, and having to take work home. Biopsychosocial consequences include anxiety, stress, and sleep disorders. There was a statistically significant association between inadequate salary and anxiety (p = 0.01) and between an excessive number of activities and stress (p = 0.01). Teachers reported that a good relationship among colleagues is a working condition that promotes well-being in the workplace. The identification of stressful working conditions for teachers, the biopsychosocial consequences, and working conditions that promote well-being in the workplace are relevant to determining actions that improve the work environment and, consequently, the health of teachers.

  20. Human genome and the african personality: implications for social work.

    2011-01-01

    The integration of the human genome with the African personality should be viewed as an interdependent whole. The African personality, for purposes of this article, comprises Black experiences, Negritude, and an Africa-centered axiology and epistemology. The outcome results in a spiritual focused collective consciousness. Anthropologically, historically (and with the Human Genome Project), genetically Africa has proven to be the source of all human life. Human kind wherever they exist on the planet using the African personality must be viewed as interconnected. Although racism and its progeny discrimination preexist the human genome project (HGP), the human genome provides an evidence-based rationale for the end to all policy and subsequent practice based on race and racism. Policy must be based on evidence to be competent practice. It would be remiss if not irresponsible of social work and the other behavioral scientist concerned with intervention and prevention behaviors to not infuse the findings of the HCPs. The African personality is a concept that provides a wholistic way to evaluate human behavior from an African worldview.

    Full Text Available Purpose. The paper supposes creation of a CFD model for calculating the air ion regime in the premises and in work areas at artificial ionization of the air by the ionizer installation indoors with considering the most important physical factors that influence the formation of ions concentration field. Methodology. The proposed CFD model for calculation of the air ion regime in work areas at artificial ionization of the air by installing ionizer indoors is based on the application of aerodynamics, electrostatics and mass transfer equations. The mass transfer equation takes into account the interaction of different polarities of ions with each other and with the dust particles. The calculation of air flow rate in the room is realized on the basis of the potential flow model by using the Laplace equation for the stream function. Poisson equation for the electric potential is used for calculation of the charged particles drift in an electric field. At the simulation to take into account: 1 influence of the working area geometric characteristics; 2 location of the ventilation holes; 3 placement of furniture and equipment; 4 ventilation regime in the room; 5 presence of obstacles on the ions dispersion process; 6 specific location of dust particles emission and ions of different polarity, and their interaction in the room and in the working zones. Findings. The developed CFD model allows determining the concentration of negative ions in the room and in the area of the human respiratory organs. The distribution of the negative ions concentration is presented in the form of concentration field isolines. Originality. The 2D CFD model for calculating the air ion regime in working areas, providing the ability to determine the ions concentration in a given place in the room was created. The proposed model is developed taking into account: placement of furniture and equipment in the room; geometric characteristics of the room; location of dust emissions

    Full Text Available Background: Physician jobs are associated with adverse psychosocial work conditions. We summarize research on the relationship of physicians' psychosocial work conditions and quality of care. Method: A systematic literature search was conducted in MEDLINE and PsycINFO. All studies were classified into three categories of care quality outcomes: Associations between physicians' psychosocial work conditions and (1 the physician-patient-relationship, or (2 the care process and outcomes, or (3 medical errors were examined. Results: 12 publications met the inclusion criteria. Most studies relied on observational cross-sectional and controlled intervention designs. All studies provide at least partial support for physicians’ psychosocial work conditions being related to quality of care. Conclusions: This review found preliminary evidence that detrimental physicians’ psychosocial work conditions adversely influence patient care quality. Future research needs to apply strong designs to disentangle the indirect and direct effects of adverse psychosocial work conditions on physicians as well as on quality of care.Keywords: psychosocial work conditions, physicians, quality of care, physician-patient-relationship, hospital, errors, review, work stress, clinicians

METHODS In this ecological study, we have analyzed data of Brazilian municipalities related to sociodemographic characteristics, coverage of care programs, structure of primary health units, and work process of primary care teams. We have obtained the data from the first cycle of the Brazilian Program for Improving Access and Quality of the Primary Care, of the Department of Information Technology of the Brazilian Unified Health System, the Brazilian Institute of Geography and Statistics, and the United Nations Development Programme. The associations have been estimated using negative binomial regression coefficients (β and respective 95% confidence intervals, with a hierarchical approach in three levels (alpha = 5%. RESULTS In the adjusted analysis for the outcome in 2013, in the distal level, the coverage of the Bolsa Família Program (β = -0.001 and private insurance (β = -0.01 had a negative association, and the human development index (β = 1.13, the proportion of older adults (β = 0.05 and children under the age of five (β = 0.05, and the coverage of the Community Health Agent Strategy (β = 0.002 showed positive association with hospitalizations for primary care sensitive conditions. In the intermediate level, minimum hours (β = -0.14 and availability of vaccines (β = -0.16 showed a negative association, and availability of medications showed a positive association (β = 0.16. In the proximal level, only the variable of matrix support (β = 0.10 showed a positive association. The variables in the adjusted analysis of the number of hospitalizations for primary care sensitive conditions in 2014 presented the same association as in 2013. CONCLUSIONS The characteristics of

    The aim of this study was to examine the awareness of work-life balance (WLB) among the nursing personnel at a university hospital in Japan. Survey. A questionnaire was sent to 1236 nursing personnel working at a university hospital and 1081 (87·5%) responses received. The questions concerned the following: (1) respondent demographical characteristics, (2) living background, (3) wishes for working environments and (4) motivation to work and health condition. The data were analysed by simple and cross-tabulations. The results can be summarised as follows: (1) the concept and significance of WLB has not yet been established among nurses in Japan, (2) three factors were found, which nurses need as working environment, 1st quality-of-life benefits, 2nd flexible working style, 3rd lifelong learning and (3) nurses who reported good WLB also reported higher job satisfaction and job motivation. The concept and significance of WLB has not yet been established among nurses. Thus, it is needed to enlighten nurses on the concept and significance of WLB as well as how they should practise WLB. Approximately half of the nurses gave their jobs first priority in reality, although they had various needs for their private lives and household affairs, as well as jobs. WLB cannot be achieved only by individual attitudes; thus, organisational efforts are necessary. In the correlation between WLB and 'job satisfaction' and 'job motivation,' nurses who were satisfied with their job and those who were highly motivated showed higher WLB. There was a significant correlation between satisfaction and motivation. It is necessary that nurses understand and have any information about working policy to improve working conditions to get better conditions which they need. © 2010 Blackwell Publishing Ltd.

    There is ample evidence that environmental stressors such as extreme weather conditions affect animal behavior and that this process is in part mediated through the elevated activity of the hypothalamic pituitary adrenal axis which results in an increase in cortisol secretion. This relationship has not been extensively researched in humans, and weather conditions have not been analyzed as a potential confounder in human studies of stress. Consequently, the goal of this paper was to assess the relationship between salivary cortisol and weather conditions in the course of everyday life and to test a possible moderating effect of two weather-related variables, the climate region and timing of exposure to outdoors conditions. The sample consisted of 903 secondary school students aged 18 to 21 years from Mediterranean and Continental regions. Cortisol from saliva was sampled in naturalistic settings at three time points over the course of a single day. We found that weather conditions are related to salivary cortisol concentration and that this relationship may be moderated by both the specific climate and the anticipation of immediate exposure to outdoors conditions. Unpleasant weather conditions are predictive for the level of salivary cortisol, but only among individuals who anticipate being exposed to it in the immediate future (e.g., in students attending school in the morning shift). We also demonstrated that isolated weather conditions or their patterns may be relevant in one climate area (e.g., Continental) while less relevant in the other (e.g., Mediterranean). Results of this study draw attention to the importance of controlling weather conditions in human salivary cortisol research.

    We conclude that environmental conditions are correlated to human Q fever incidence rate. Similar research with data from other outbreaks would be needed to more firmly establish our findings. This could lead to better estimations of the public health risk of a C. burnetii outbreak, and to more detailed and accurate hazard maps that could be used for spatial planning of livestock operations.

    Full Text Available Abstract Background Early retirement due to disability is a public health and work environment problem that shortens working careers. Transition to disability retirement is based on ill-health, but working conditions are also of relevance. We examined the contributions of work arrangements, physical working conditions and psychosocial working conditions to subsequent disability retirement. Methods The data were derived from the Helsinki Health Study cohort on employees of the City of Helsinki, Finland. Information on working conditions was obtained from the baseline surveys conducted in 2000, 2001 and 2002. These data were linked with register data on disability retirement and their main diagnoses obtained from the Finnish Centre for Pensions. Follow up by the end of 2008 yielded 525 disability retirement events. The analysed data included 6525 participants and 525 disability retirement events. Hazard ratios (HR and 95% confidence intervals (95% CI were calculated from Cox regression analysis. Results Several working conditions showed own associations with disability retirement before adjustment. After adjustment for all working conditions, the primary risk factors for all-cause disability retirement were physical workload among women (HR 2.02, 95% CI 1.57-2.59 and men (HR 2.00, 95% CI 1.18-3.38, and low job control among women (HR 1.60, 95% CI 1.29-1.99. In addition, for disability retirement due to musculoskeletal causes, the risk factors were physical workload and low job control. For disability retirement due to mental causes the risk factors were computer work and low job control. Furthermore, occupational class was a risk factor for disability retirement due to all causes and musculoskeletal diseases. Conclusions Among various working conditions, those that are physically demanding and those that imply low job control are potential risk factors for disability retirement. Improving the physical working environment and enhancing control over

    The aim of the present study was to conduct subgroup-analyses in a prospective cohort of workers on long-term sickness absence to investigate whether associations between perceived work attitude, self-efficacy and perceived social support and time to RTW differ across different health conditions. The study was based on a sample of 926 workers on sickness absence (6-12 weeks). The participants filled out a baseline questionnaire and were subsequently followed until the tenth month after listing sick. Perceived work attitude was measured with a Dutch language version of the Work Involvement Scale. Perceived social support was measured with a self-constructed standardized scale reflecting a person's perception of social support regarding RTW. Self-efficacy was measured with the standardised Dutch version of the General self-efficacy scale, assessing the subjects' expectations of their general capacities. The sample was divided into three subgroups: musculoskeletal health conditions, other physical health conditions and mental health conditions. Anova analyses and Cox proportional hazards regression analyses were used to identify differences in association between the three factors and the time to RTW between different subgroups. The associations between the perceived work attitude, self-efficacy and perceived social support and the time to RTW vary across different health condition subgroups, not only with regard to the strength of the association but also for the type of factor. In the multivariate model, hazard ratios (HRs) of 1.33 (95% CI 1.01-1.75) in the musculoskeletal subgroup, and 1.26 (95% CI 0.89-1.78) in the other physical subgroup were found in perceived work attitude. With regard to perceived social support HRs of 1.39 (95% CI 1.12-1.99) respectively 1.51 (1.05-2.17) in the same subgroups were found. Only self-efficacy remained in the multivariate model in all subgroups with HRs of 1.49 (95% CI 1.12-1.99) in the musculoskeletal subgroup, 1.53 (95% CI 1

    2010-11-01

    Full Text Available Working conditions of agricultural workers, like industrial, are one of the burning issues in a developing region. It is related to agricultural activities of the workers and their socio-economic status. Working conditions may be both favourable and unfavourable. Those working conditions which are unfavourable to health may be considered as occupational hazards or as a part of occupational environment. It is generally observed that a large section of the agricultural workers remains engaged in agricultural practices at the time of hunger, thirst, pregnancy (women and even despite their unpleasant state of health, both mental and physical. They also continue to work for more than the prescribed standard hours and also having half-fed. These are not positive or favourable working conditions to their health as they normally cause general weakness, fatigue, stomach disorder, dizziness, headache, loss of energy and some other similar physical, mental and psychological problems. The major driving forces behind as such adverse working conditions and its consequences are the pressure of work, pressure of land owners and of timely completion of works, shortage of manpower, psychological attitude, ignorance, weather constraints, poverty, illiteracy, lack of work related health awareness, lower social and economic status, etc. Such forces compel the workers to be engaged in their agricultural practices under the above circumstance. Adverse working conditions of agricultural workers vary widely with reference to space, time, activities, demographics, society, economy and consequently affect both the mental and physical, social and psychological conditions of the agricultural workers. Persons in varying number in the age groups from 15-34 and 35-49 to 60 & + year were reported working under different types of undesirable working conditions. The people from the S.C. and S.T. categories are the major sufferers as most of them continue their work during

    Background A growing number of German hospitals have been privatized with the intention of increasing cost effectiveness and improving the quality of health care. Numerous studies investigated what possible qualitative and economic consequences these changes issues might have on patient care. However, little is known about how this privatization trend relates to physicians' working conditions and job satisfaction. It was anticipated that different working conditions would be associated with different types of hospital ownership. To that end, this study's purpose is to compare how physicians, working for both public and privatized hospitals, rate their respective psychosocial working conditions and job satisfaction. Methods The study was designed as a cross-sectional comparison using questionnaire data from 203 physicians working at German hospitals of different ownership types (private for-profit, public and private nonprofit). Results The present study shows that several aspects of physicians' perceived working conditions differ significantly depending on hospital ownership. However, results also indicated that physicians' job satisfaction does not vary between different types of hospital ownership. Finally, it was demonstrated that job demands and resources are associated with job satisfaction, while type of ownership is not. Conclusion This study represents one of a few studies that investigate the effect of hospital ownership on physicians work situation and demonstrated that the type of ownership is a potential factor accounting for differences in working conditions. The findings provide an informative basis to find solutions improving physicians' work at German hospitals. PMID:19678932

    When considering working conditions, the myth sometimes holds that small is beautiful. Some studies of occupational accidents show that small companies have fever accidents than large. This indicates that small companies have better working conditions than large. A Danish study based on a random...... sample of employees in the general industry rejects this myth. The figures show that physical working conditions become systematically worse the smaller the size of privately owned companies. The study also supports international data that small companies underreport accidents, and that this might...

    The Working Memory model of human memory, first introduced by Baddeley and Hitch (1974), has been one of the most influential psychological constructs in cognitive psychology and human neuroscience. However the neuronal correlates of core components of this model have yet to be fully elucidated. Here we present data from two studies where human temporal cortical single neuron activity was recorded during tasks differentially affecting the maintenance component of verbal working memory. In Study One we vary the presence or absence of distracting items for the entire period of memory storage. In Study Two we vary the duration of storage so that distractors filled all, or only one-third of the time the memory was stored. Extracellular single neuron recordings were obtained from 36 subjects undergoing awake temporal lobe resections for epilepsy, 25 in Study one, 11 in Study two. Recordings were obtained from a total of 166 lateral temporal cortex neurons during performance of one of these two tasks, 86 study one, 80 study two. Significant changes in activity with distractor manipulation were present in 74 of these neurons (45%), 38 Study one, 36 Study two. In 48 (65%) of those there was increased activity during the period when distracting items were absent, 26 Study One, 22 Study Two. The magnitude of this increase was greater for Study One, 47.6%, than Study Two, 8.1%, paralleling the reduction in memory errors in the absence of distracters, for Study One of 70.3%, Study Two 26.3% These findings establish that human lateral temporal cortex is part of the neural system for working memory, with activity during maintenance of that memory that parallels performance, suggesting it represents active rehearsal. In 31 of these neurons (65%) this activity was an extension of that during working memory encoding that differed significantly from the neural processes recorded during overt and silent language tasks without a recent memory component, 17 Study one, 14 Study two

  2. Categories, concepts, and conditioning: how humans generalize fear.

    During the past century, Pavlovian conditioning has served as the predominant experimental paradigm and theoretical framework to understand how humans learn to fear and avoid real or perceived dangers. Animal models for translational research offer insight into basic behavioral and neurophysiological factors mediating the acquisition, expression, inhibition, and generalization of fear. However, it is important to consider the limits of traditional animal models when applied to humans. Here, we focus on the question of how humans generalize fear. We propose that to understand fear generalization in humans requires taking into account research on higher-level cognition such as category-based induction, inferential reasoning, and representation of conceptual knowledge. Doing so will open the door for productive avenues of new research.

    This analysis used propensity score matching to construct a comparison sample that is observationally similar at baseline interview to older workers who later experience the onset of a medical condition that limits their ability to work. Using these matched onset and comparison samples, we studied trajectories in earnings and income around onset of the work limitation. Earnings two years after onset for the work-limitation group were 50% lower and poverty rates were nearly double. Income from unemployment insurance, workers' compensation, and retirement and disability benefits offset only a small amount of the earnings declines, resulting in decreased overall household income after onset of the work-limiting condition.

    This study aims to provide reflection points on the nursing management process in the current state impoverishment financial conditions facing nursing work in a public health service in the State of Mato Grosso. We used the concepts of vulnerability, user rights and ethic to seek to understand how these concepts can broaden the view of citizenship in the search for better health care conditions for the users and workers in the institution studied. The blatant impoverishment of conditions that was detected point to the need for more awareness raising all levels where we think about, carry out and submit ourselves to the health care Nursing, working conditions, nursing ethics.

  5. [Arduous working conditions for beginners: when workplace prevention becomes an economic risk].

    Latil, François

    2015-01-01

    The French law of 20.01.2014 recently instituted an arduous working conditions allowance. This innovated legislation is designed to improve the status of workers subject to arduous working conditions either by allowing lighter work schedules or job reclassification or early retirement. The impact of arduous working conditions on health has been clearly established, but no consensual solution has yet been proposed. Life expectancy without disability can differ by as much as 9 years between higher executives and manual workers, but the proposed solutions comprise a multitude of perverse effects. Workers may benefit from maintaining their arduous working conditions in order to preserve their right to early retirement. Companies do not necessarily have the desire or the resources to invest in prevention, which is the only consensually accepted effective measure, if they are also required to finance both training and retirement. In particular, management of the arduous working conditions allowance is very complex and entirely financed by companies. Consequently, company productivity can be impacted, leading to transfers of company headquarters, outsourcing to interim workers, replacement of jobs by automation. Unemployment could be the big winner of this conflict. Politically, arduous working conditions allowance appears to be very difficult to put into practice and can be considered to be more a promise by the government to the left and to the trade unions.

  6. Hospital nurses' working conditions in relation to motivation and patient safety.

    There is a lack of empirical knowledge about nurses' perceptions of their workplace characteristics and conditions, such as level of autonomy and decision authority, work climate, teamwork, skill exploitation and learning opportunities, and their work motivation in relation to practice outputs such as patient safety. Such knowledge is needed particularly in countries, such as Estonia, where hospital systems for preventing errors and improving patient safety are in the early stages of development. This article reports the findings from a cross-sectional survey of hospital nurses in Estonia that was aimed at determining their perceptions of workplace characteristics, working conditions, work motivation and patient safety, and at exploring the relationship between these. Results suggest that perceptions of personal control over their work can affect nurses' motivation, and that perceptions of work satisfaction might be relevant to patient safety improvement work.

    This is a study of qualitative and dialectical approach, which subject is to analyze the working conditions of the traditional birth attendants, in a reproductive perspective of work, and for this reason, economically undervalued. The analysis has been constructed having as central category the work, under marxist and feminist premises. Obtained results permit us to state these traditional birth attendants do their work in material and financial poor conditions, related to transportation, access, and still, working environment. The analysis of this practice has given us a possibility to present a discussion on some traits of the traditional birth attendant's work, which is characterized as a reproductive work, economically undervalued, autonomous and eminently feminine. It still configures as a social practice of popular health, legitimated by the community. In the rural domestic obstetrics practice, unequal relations were in evidence since men and women play different roles in the same occupation, being women's responsability the reproduction of the feminine role.

    The purpose of this study was to identify the working conditions and workplace barriers to vocal health in primary school teachers. The relationship between working conditions and voice is analyzed. This is a survey study in 42 randomized schools from a restricted geographical area. An 85-item questionnaire was administered to 550 primary school teachers in 42 schools in Dublin. It was designed to obtain information on demographics, vocal use patterns, vocal health, work organization, working conditions, and teacher's perceptions of the conditions in teaching that might cause a voice problem. The relationship between voice and overstretched work demands, and voice and class size, was examined. A chi-squared test was run to test the null hypothesis that the variables overstretched work demands and voice and class size and voice are independent. Subjects were given the opportunity to give their opinion on their working conditions and on the availability of advice and support within the workplace. A final question sought their opinion on what should be included in a voice care program. A 55% response rate was obtained (n = 304). It was found with 96.52% confidence that the variables overstretched work demands and voice are related. Likewise, it was found that the variables class size and voice are related with 99.97% confidence. There are workplace barriers to vocal health. The working conditions of primary school teachers need to be fully adapted to promote vocal health. Changes by education and health policy makers are needed to achieve this goal. There is a need for future research which focuses on the working conditions of teachers. Copyright © 2016. Published by Elsevier Inc.

    Full Text Available Background: patients with human immunodeficiency virus frequently develop skin conditions that affect their quality of life and modify their prognosis. Objective: to describe the most common skin conditions in patients with human immunodeficiency virus. Methods: a case-series study of patients with human immunodeficiency virus was conducted in the province of Cienfuegos. It included all patients diagnosed until February 2008 attending the internal medicine consultation for their follow-up. Forty-seven deceased patients, 12 patients not living in the province and 2 inmates were excluded from the study. Variables analyzed were: age, sex, skin color, self-reported skin conditions and diagnosed skin diseases. Results: Thirty-eight percent of patients were aged 25 to 34 years. Fifty-seven were white-skinned and 75% were male. Approximately half of the patients had AIDS and were under antiretroviral therapy. The skin infection of viral origin most commonly found was herpes simplex (30.0%; of fungal origin, onychomycosis (44 %; and of bacterial origin, folliculitis (43 %. Among papulosquamous disorders, seborrheic dermatitis (74 % predominated and among other skin disorders, lipodystrophy (23.6 %. Xerosis and pruritus shared equal percentage (16.3 %. Conclusions: viral and fungal skin infections predominated. An important number of these skin conditions were diagnosed during the study, particularly in AIDS patients.

    Ryan, T.G.

    1995-10-01

    A workshop was conducted whose specific purpose was to build on earlier work of the United States National Research Council, United States Federal government agencies, and the larger human factors community to: (1) clarify human factors issues pertaining to degraded performance in advanced human-machine systems (e.g., nuclear production, transportation, aerospace) due to human work underload and workload transition, and (2) develop strategies for resolving these issues. Recent history demonstrates that: (1) humans often react adversely to their diminishing roles in advanced human-machine systems, and therefore (2) new allocation models and strategies are required if humans are to be willing and able to assume diminishing and shifting roles assigned to them in these systems, and are to accept new technologies making up these systems. Problems associated with theses diminishing and shifting human roles are characterized as work underload and workload transitions. The workshop affirmed that: (1) work underload and workload transition are issues that will have to be addressed by designers of advanced human-machine systems, especially those relying on automation, if cost, performance, safety, and operator acceptability are to be optimized, (2) human machine allocation models, standards, and guidelines which go beyond simple capability approaches will be needed to preclude or seriously diminish the work underload and workload transition problems, and (3) the 16 workload definition, measurement, situational awareness, and trust issues identified during the workshop, need resolution if these models, standards, and guidelines are to be achieved.

    Directory of Open Access Journals (Sweden)

    Antonio Geraldo Cantarela

    2015-04-01

    Full Text Available Language as a human possibility of telling its world experience carries an unsolvable condition of not saying it all. Although it may refer to everything, language does not exhaust  the enunciable. The different speeches about God are also in the dynamic and apparently paradoxal game of the capability of the human language of covering or not the world. The religious language in its wish to talk about the mysterious reality of the Deity does frequently so through metaphors – a basic constitutive element of the poetic speech. Based on these assumptions- on the theoretical trail of the hermeneutics by Gadamer and Ricoeur –, the paper studies some selected texts by Mia Couto to state that if the Numinous cannot be adequately named, on the other hand the names we make up for us can talk about God. More exactly, the character-names created by the Mozambican writer, despite the fact of being aphasic and crazy because they stage precisely the marginal human condition, are shown with an intense deciphering power of the world. This is why they are offered as an instigating theologizable literary construct.Keywords: Mia Couto. Mozambican Literature. Literary Criticism. Theology. Theopoetics

    Ranking of workplaces with respect to working conditions is very significant for each company. It indicates the positions where employees are most exposed to adverse effects resulting from the working environment, which endangers their health. This article presents the results obtained for 12 different production workplaces in the copper mining and smelting complex RTB Bor - 'Veliki Krivelj' open pit, based on six parameters measured regularly which defined the following working environment conditions: air temperature, light, noise, dustiness, chemical hazards and vibrations. The ranking of workplaces has been performed by PROMETHEE/GAIA. Additional optimization of workplaces is done by PROMETHEE V with the given limits related to maximum permitted values for working environment parameters. The obtained results indicate that the most difficult workplace is on the excavation location (excavator operator). This method can be successfully used for solving similar kinds of problems, in order to improve working conditions.

  18. Dependency in autonomous caring--night nurses' working conditions for caring in nursing.

    2010-06-01

    Few research studies have focused on nurses' working conditions for caring provided at night, and these studies have mainly described nurses' work in hospital settings, not in a municipal, social-care context. In Swedish municipal care, nurses have responsibility for hundreds of older people in need of care. This working condition compromises caring encounters; instead the nurses' caring is mainly mediated through care staff (or relatives). In considering that caring based on caring encounters is fundamental to ethical nursing practice questions leads to the aim: to explore Swedish municipal night nurses' experiences of their working conditions for caring in nursing. All municipal night-duty nurses (n = 7) in a medium-sized community in Sweden participated in interviews, while six of them also wrote diaries. Thematic content analysis has been used in analysing the data. The findings revealed that the nurses experienced their working conditions for caring in nursing in the themes of Dependency in the Organisation and Other Staff, Vocational Responsibility, Deficiency in Conditions for Caring and Autonomous Caring. The findings illustrate privileged, as well as, poor working conditions for caring in nursing. The nurses' role as consultants emerge as their main function. The consultant function implies that nurses do not participate in ordinary bed-side caring, which makes it easier for them to find time for caring in situations that arise when nurses' skills, expertise and authority are called upon. Conversely the consultancy function entails short-term solution of complex caring problems, which can signify deficient caring due to prevailing working conditions. The findings also point to nurses' possible problems in fulfilling their own and vocational demands for ethics in the practice of caring in nursing related to existing working conditions.

    Full Text Available Abstract Background Sick-leave because of mental and behavioural disorders has increased considerably in Sweden since the late nineties, and especially in women. The aim of this study was to assess the level of burnout in the general working population in northern Sweden and analyse it's relation to working conditions and gender. Methods In this cross-sectional study the survey from the MONICA-study (Monitoring of Trends and Determinants in Cardiovascular Disease in northern Sweden 2004 was used. A burnout instrument, the Shirom Melamed Burnout Questionnaire (SMBQ, was incorporated in the original survey which was sent to a random sample of 2500 individuals with a response rate of 76%. After including only actively working people, aged 25-64 years, our study population consisted of 1000 participants (497 women and 503 men. ANOVA and multiple linear regression models were used. Results The prevalence of a high level of burnout (SMBQ >4.0 was 13%. Women had a higher level of burnout than men with the most pronounced difference in the age group 35-44 years. In both sexes the level of burnout decreased with age. Demand and control at work, and job insecurity were related to burnout. In women the level of education, socioeconomic position, work object, and working varying hours were of importance. Interaction effects were found between sex and work object, and sex and working hours. In a multiple regression analysis almost half of the gender difference could be explained by work related and life situational factors. Conclusions Working life conditions contributed to the level of burnout in this actively working sample from the general population in northern Sweden. Especially in women, socioeconomic position was associated with burnout. The high level of burnout in women compared to men was partly explained by more unfavourable working conditions and life situational factors. Efforts to level out gender differences in burnout should probably focus on

    Early retirement is an increasing problem in the construction industry. There is limited information about causes leading employees to leave working life early. We have compared construction workers present situation with their perception of future demands at work to avoid early retirement. All 87 employees in a medium-sized Norwegian construction company participated in the study. All were men and answered questionnaires on health and pain, work ability, mechanical exposure, psychosocial conditions, and demands regarding future working conditions. Most workers showed good work ability, irrespective of age. Many reported high levels of mechanical exposure at work. The level of musculoskeletal pain was higher in the middle-aged (30-50 year old) age groups and seniors aged over 50 years than among the youngest workers less than 30 years of age. All workers reported that good health was important for continued working. Most workers stated that future work must not be too physically demanding. Many workers reported relatively low job satisfaction; consequently an interesting job was rated as important for continuing work. Good social conditions were a high priority. According to the examined construction workers, good health and reduced levels of mechanical exposure at work are essential to avoid early retirement.

    The aim of this study was to evaluate working conditions with a notebook computer (notebook) as a potential cause of musculoskeletal disorders. The study had 2 stages. The first one was a questionnaire survey among 300 notebook users. The next stage was an expert analysis of 53 randomly selected workstations. The questionnaire survey included questions about the participants, their working conditions, work organization and also duration of work with a notebook. The results of the research showed that most examined operators used a notebook as a basic working tool. The most important irregularities included an unadjustable working surface, unadjustable height of the seat pan and backrest, unadjustable height and distance between the armrests and no additional ergonomic devices (external keyboard, docking station, notebook stand or footstool).

    In safety-critical systems, the generation failure of an actuation signal is caused by the concurrent failures of the automated systems and an operator action. These two sources of safety signals are complicatedly correlated. The failures of sensors or automated systems will cause a lack of necessary information for a human operator and result in error-forcing contexts such as the loss of corresponding alarms and indications. In the conventional analysis, the Human Error Probabilities (HEP) are estimated based on the assumption of 'normal condition of indications and alarms'. In order to construct a more realistic signal-generation failure model, we have to consider more complicated conditions in a more realistic manner. In this study, we performed two kinds of investigation for addressing this issue. We performed the analytic calculations for estimating the effect of sensors failures on the system unavailability and plant risk. For the single-parameter safety signals, the analysis result reveals that the quantification of the HEP should be performed by focusing on the 'no alarm from the automatic system and corresponding indications unavailable' situation. This study also proposes a Condition-Based Human Reliability Assessment (CBHRA) method in order to address these complicated conditions in a practical way. We apply the CBHRA method to the manual actuation of the safety features such as a reactor trip and auxiliary feedwater actuation in Korean Standard Nuclear Power Plants. In the case of conventional single HEP method, it is very hard to consider the multiple HE conditions. The merit of CBHRA is clearly shown in the application to the AFAS generation where no dominating HE condition exits. In this case, even if the HE conditions are carefully investigated, the single HEP method cannot accommodate the multiple conditions in a fault tree. On the other hand, the application result of the reactor trip in SLOCA shows that if there is a

    Investigations concerning adult personality development have increasingly focused on factors that are associated with apparent personality trait changes. The current study contributes to this literature by replicating and extending previous research concerning personality trait development in young adulthood and perceptions of workplace conditions. Analyses were based on up to 442 individuals who participated in the ongoing Family Transitions Project (e.g., Conger & Conger, 2002). The current analyses included personality trait data from 1994 and 2003, high school grades and socioeconomic status indicators from 1994, and reports about work conditions in 2001, 2003, and 2005. Personality attributes were prospectively associated with work conditions and income. Findings also support the corresponsive principle of personality development (e.g., Roberts, Caspi, & Moffitt, 2003): Traits that were prospectively associated with particular workplace conditions often seemed to be accentuated by those conditions. Personality traits are prospectively associated with perceptions of the workplace. Workplace conditions are also associated with trait development. © 2013 Wiley Periodicals, Inc.

    In order to understand the problem of poverty its historical background must be elucidated. Since in the past most people in Europe were peasants living in small villages, a useful, initial way to examine the question of poverty is to investigate the villagers' condition of life. A basic contribution to this endeavor is to compile a food balance sheet that includes the food energy necessary for a healthy population, the amount of food in terms of calories that was available and the human energy required for the production of the nutriments. This essay is a case-study, incorporating these variables for the village Unterfinning (Bavaria) in 1721.

    Human scent evidence collected from objects at a crime scene is used for scent discrimination with specially trained canines. Storage of the scent evidence is usually required yet no optimized storage protocol has been determined. Storage containers including glass, polyethylene, and aluminized pouches were evaluated to determine the optimal medium for storing human scent evidence of which glass was determined to be the optimal storage matrix. Hand odor samples were collected on three different sorbent materials, sealed in glass vials and subjected to different storage environments including room temperature, -80 degrees C conditions, dark storage, and UVA/UVB light exposure over a 7-week period. Volatile organic compounds (VOCs) in the headspace of the samples were extracted and identified using solid-phase micro-extraction-gas chromatography/mass spectrometry (SPME-GC/MS). Three-dimensional covariance mapping showed that glass containers subjected to minimal UVA/UVB light exposure provide the most stable environment for stored human scent samples.

    1998-06-01

    Pavlovian conditioning of the human male sexual response may be involved in the ontogenetic development of sexual interests and may be responsible for individual differences. We attempted to demonstrate Pavlovian conditioning of sexual interests in a nonclinical sample of adult males. Ten participants were exposed to 11 pairings of a slide of a moderately attractive, partially nude female adult (TARGET) and a highly arousing videotape depiction of heterosexual sexual interactions (US). Ten other participants were exposed to 11 presentations of the TARGET alone. Participants exposed to the TARGET-US contingency showed a 10% relative increase in sexual arousal to the TARGET; participants exposed to the TARGET-ALONE contingency showed an 11% relative decrease in sexual arousal to the TARGET. This group difference is interpreted as resulting from both conditioning and habituation.

    2011-01-01

    Shampoo treatment and hair conditioning have a direct impact on our wellbeing via properties like combability and haptic perception of hair. Therefore, systematic investigations leading to quality improvement of hair care products are of major interest. The aim of our work is a better understanding of complex testing and the correlation with quantitative parameters. The motivation for the development of physical testing methods for hair feel relates to the fact that an ingredient supplier like BASF can only find new, so far not yet toxicologically approved chemistries for hair cosmetics, if an in-vitro method exists.In this work, the effects of different shampoo treatments with conditioning polymers are investigated. The employed physical test method, dry friction measurements and AFM observe friction phenomena on a macroscopic as well as on a nanoscale directly on hair. They are an approach to complement sensoric evaluation with an objective in-vitro method.

    Food workers' health and hygiene are common pathways to foodborne disease outbreaks. Improving food system jobs is important to food safety because working conditions impact workers' health, hygiene, and safe food handling. Stakeholders from key industries have advanced working conditions as an issue of public safety in the United States. Yet, for the food industry, stakeholder engagement with this topic is seemingly limited. To understand this lack of action, we interviewed key informants from organizations recognized for their agenda-setting role on food-worker issues. Findings suggest that participants recognize the work standards/food safety connection, yet perceived barriers limit adoption of a food safety frame, including more pressing priorities (e.g., occupational safety); poor fit with organizational strategies and mission; and questionable utility, including potential negative consequences. Using these findings, we consider how public health advocates may connect food working conditions to food and public safety and elevate it to the public policy agenda.

    2016-01-01

    Brain region-specific changes have been demonstrated with a variety of cognitive training interventions. The effect of cognitive training on brain subnetworks in humans, however, remains largely unknown, with studies limited to functional networks. Here, we used a well-established working memory training program and state-of-the art neuroimaging methods in 40 healthy adults (21 females, mean age 26.5 years). Near and far-transfer training effects were assessed using computerized working memory and executive function tasks. Adaptive working memory training led to improvement on (non)trained working memory tasks and generalization to tasks of reasoning and inhibition. Graph theoretical analysis of the structural (white matter) network connectivity (“connectome”) revealed increased global integration within a frontoparietal attention network following adaptive working memory training compared with the nonadaptive group. Furthermore, the impact on the outcome of graph theoretical analyses of different white matter metrics to infer “connection strength” was evaluated. Increased efficiency of the frontoparietal network was best captured when using connection strengths derived from MR metrics that are thought to be more sensitive to differences in myelination (putatively indexed by the [quantitative] longitudinal relaxation rate, R1) than previously used diffusion MRI metrics (fractional anisotropy or fiber-tracking recovered streamlines). Our findings emphasize the critical role of specific microstructural markers in providing important hints toward the mechanisms underpinning training-induced plasticity that may drive working memory improvement in clinical populations. SIGNIFICANCE STATEMENT This is the first study to explore training-induced changes in the structural connectome using a well-controlled design to examine cognitive training with up-to-date neuroimaging methods. We found changes in global integration based on white matter connectivity within a

    In adverse working conditions, environmental parameters such as metallic dust, noise, and environmental temperature, directly affect the health condition of manufacturing workers. It is therefore important to implement health monitoring and management based on important physiological parameters (e.g., heart rate, blood pressure, and body temperature). In recent years, new technologies, such as body area networks, cloud computing, and smart clothing, have allowed the improvement of the quality of services. In this article, we first give five-layer architecture for health monitoring and management of manufacturing workers. Then, we analyze the system implementation process, including environmental data processing, physical condition monitoring and system services and management, and present the corresponding algorithms. Finally, we carry out an evaluation and analysis from the perspective of insurance and compensation for manufacturing workers in adverse working conditions. The proposed scheme will contribute to the improvement of workplace conditions, realize health monitoring and management, and protect the interests of manufacturing workers.

    Full Text Available Background: Beedi rollers are exposed to unburnt tobacco dust through cutaneous and pharyngeal route. They are not aware of their rights. Studies have been conducted on beedi workers but not many studies are carried out in urban areas. Thus, study was carried out to understand working condition and health hazards in beedi workers residing in the urban slums of Mumbai and to know whether beedi roller are in better condition in urban areas. Aim: To study working condition and health hazard in beedi rollers in the urban slums. Materials and Methods: Descriptive, cross-sectional, community based study was carried in the urban slums of Mumbai with population of 8985 from April 2011 to June 2011. With snow balling sampling technique, 52 beedi workers were interviewed regarding their socio-economic status, working conditions and health problems after informed consent. Data entry and statistical analysis were performed using the SPSS windows version 14.0 software. Results: The mean age was 45 years with SD of 12 years. All were Hindu females. Around 42.31% were illiterate. Mean years of service were 30 years and they work on an average for eight hours. Children were not involved in beedi rolling. Most common morbidity was fatigue. None were aware of the benefits provided for them. Awareness regarding health hazard and safety measures was poor. Conclusions: The working condition of beedi rollers in the urban areas is not favourable.

    Full Text Available Employment and working conditions are key social determinants of health, yet current information is lacking regarding relationships between foreign background status, working conditions and health among workers in Sweden. This study utilized cross-sectional data from the 2010 Swedish Level of Living Survey (LNU and the Level of Living Survey for Foreign Born Persons and their Children (LNU-UFB to assess whether or not health inequalities exist between native Swedish and foreign background workers and if exposure to adverse psychosocial and physical working conditions contributes to the risk for poor health among foreign background workers. A sub-sample of 4,021 employed individuals aged 18–65 was analyzed using logistic regression. Eastern European, Latin American and Other Non-Western workers had an increased risk of both poor self-rated health and mental distress compared to native Swedish workers. Exposure to adverse working conditions only minimally influenced the risk of poor health. Further research should examine workers who are less integrated or who have less secure labor market attachments and also investigate how additional working conditions may influence associations between health and foreign background status.

    Full Text Available Background: Background: Carpet weaving operations usualy involve poor working conditions that can lead to the development of musculoskeletal disorders (MSDs. This study investigated MSDs among car-pet weavers in relation to working conditions from workers' view in Tabriz City, Northwest Iran.Method: This cross-sectional and descriptive study was conducted in city of Tabriz, Iran. Data were col-lected using interviews and questionnaires. The study population consisted of 200 randomly selected healthy weavers from twenty five active carpet weaving workshops.Results: The results showed a high prevalence of musculoskeletal problems among the study population. The most commonly affected body areas were neck, lower back, ankles/feet, hands/wrists, upper back, shoulders and knees, respectively. More than half of the weavers were not satisfied with the thermal con-dition, noise level and cleanliness of the air in the workshops. The result indicated a significant relation-ship between upper back symptoms and daily working time and between lower back symptoms and the numbers of rows of knots woven in a day. Weavers' satisfaction with hand tools shape and thermal condi-tion of the workshops were associated with lower back symptoms, whereas satisfaction with weaving looms were associated with upper back complaints.Conclusion: The poor working condition of hand-woven carpet workshops such as environmental conditionsand work station design and tools should be the subject of ergonomics interventions.

    Full Text Available Objective: In this cross-sectional study, we investigated working conditions and related neuropsychiatric problems of shoemakers, including child workers, working in poor conditions with high health risks. Clinical diagnosis was not the objective of this study. Materials and Methods: We collected data from 318 workers ranging from 8-66 years of age. We evaluated working conditions, neuropathy symptoms and signs; urinary 2,5-hexanedione was used to estimate hexane exposure. We used the Zung depression scale for adult shoemakers to evaluate depression. Results: All workshops employed fewer than 10 workers with median daily work duration of 12h. Smoking and alcohol consumption were high among all workers including children. Peripheral neuropathy symptoms and signs were observed in 88 workers (27.8% and it was related to alcohol consumption. Sixty-eight workers (47.9% had depression and it was associated with daily work duration. Conclusion: Extremely poor, unhygienic, working conditions and a high prevalence of neuropsychiatric disorders were the main problems observed among shoemakers. A high number of child workers increased the scale of these observed problems.

    Full Text Available Introduction. Nurses often experience work-related stress. High stress can negatively affect job satisfaction and lead to emotional exhaustion with risk of burnout. Aim. To analyse possible differences in biological stress markers, psychosocial working conditions, health, and well-being between nurses working in two different departments. Methods. Stress was evaluated in nurses working in a neonatal intensive care unit (NICU (n=33 and nurses working in a child and adolescent psychiatry inpatient ward (CAP (n=14 using salivary cortisol and HbA1c. Salivary cortisol was measured three times a day on two consecutive days during two one-week periods, seven weeks apart (= 12 samples/person. Psychosocial working conditions, health, and well-being were measured once. Results. NICU nurses had better social support and more self-determination. CAP nurses had a lower salivary cortisol quotient, poorer general health, and higher client-related burnout scores. Conclusion. When comparing these nurses with existing norm data for Sweden, as a group their scores reflect less work-related stress than Swedes overall. However, the comparison between NICU and CAP nurses indicates a less healthy work situation for CAP nurses. Relevance to Clinical Practice. Healthcare managers need to acknowledge the less healthy work situation CAP nurses experience in order to provide optimal support and promote good health.

    Full Text Available Background: Good organisation of work, clear division of responsibilities, support from superiors are factors that positively influence the satisfaction of the profession. The purpose of the work was the assessment of psychosocial working conditions of nurses. Material and Methods: The research included 388 nurses working at surgical wards, medical treatment wards, and psychiatric wards. The research method was a diagnostic survey carried out by means of a questionnaire called Psychosocial Work Conditions. The obtained results were statistically analysed. Results: Nearly a half of the nurses considers the requirements at work as moderate, and 36.66% as high. Nurses from medical treatment wards indicate the highest level of requirements. Nurses working at psychiatric wards and in a shift system significantly more often feel the requirements relating to overload and resulting from a conflict of roles. Nurses working in the profession for more than 10 years considerably more often describe the level of behavioural control as high in comparison to those working for a shorter time. Regardless of the character of a ward, nurses most often (44.33% assess the support from co-workers as average, and 1/5 considered this as low. Conclusions: The results indicate the correctness of introducing psychosocial training for professionally active nurses. Med Pr 2014;65(2:173–179

    A small oxygen factory in Cantho Province located in the Mekong Delta Area in the southern part of Vietnam was studied to provide practical support measures to improve night and shift work. A direct observation study and a fatigue symptom survey during the work were conducted. The factory applied discontinuous two-shift systems in two teams. Depending on customers' demands, they frequently prolonged oxygen production until midnight. The study results showed work-related risks such as carrying heavy oxygen cylinders, workers' sleepiness during the night work, and increased fatigue feelings among production operators. Based on the study results, better strategies for night and shift work schedules such as regular work hours minimizing overtime and night work were discussed with the managers and workers. A follow-up visit three months later confirmed many improvements undertaken in the factory. Better work arrangements for night and shift workers were made including local lighting, resting corners, filling the height gaps on the work floors, and clear work instructions. Prolonged mid-night shift was stopped. It was concluded that local small enterprises in Vietnam have much potential to improve their conditions of shift and night work once practical support measures based on their local practice is given.

    Iron is essential in cellular proliferation and survival based on its crucial roles in DNA and ATP synthesis. Tumor cells proliferate rapidly even in patients with low serum iron, although their actual mechanisms are not well known. To elucidate molecular mechanisms of efficient tumor progression under the hypoferric condition, we studied the roles of six-transmembrane epithelial antigen of the prostate family member 3 (STEAP3), which was reported to facilitate iron uptake. Using Raji cells with low STEAP3 mRNA expression, human STEAP3-overexpressing cells were established. The impact of STEAP3 expression was analyzed about the amount of iron storage, the survival under hypoferric conditions in vitro and the growth of tumor in vivo. STEAP3 overexpression increased ferritin, an indicator of iron storage, in STEAP3-overexpressing Raji cells. STEAP3 gave Raji cells the resistance to iron deprivation-induced apoptosis. These STEAP3-overexpressing Raji cells preserved efficient growth even in hypoferric mice, while parental Raji cells grew less rapidly. In addition, iron deficiency enhanced STEAP3 mRNA expression in tumor cells. Furthermore, human colorectal cancer tissues exhibited more STEAP3 mRNA expression and iron storage compared with normal colon mucosa. These findings indicate that STEAP3 maintains iron storage in human malignant cells and tumor proliferation under the hypoferric condition. -- Highlights: {yields} STEAP3 expression results in increment of stored intracellular iron. {yields} Iron deprivation induces expression of STEAP3. {yields} Colorectal cancer expresses STEAP3 highly and stores iron much. {yields} STEAP3 expressing tumors preserves growth even in mice being hypoferremia.

    Employee commitment to the organization is a crucial issue in today's health-care market. In Iran, few studies have sought to evaluate the factors that contribute to forms of commitment. The aim of this study was to investigate the relationship between nurses' organizational commitment, work environment conditions, and life satisfaction. A cross-sectional design was utilized. Questionnaires were distributed to all the staff nurses who had permanent employment (with at least 2 years of experience in nursing) in the five hospitals affiliated to Birjand Medical Sciences University. Two hundred and fifty participants returned completed questionnaires. Most were female and married. The correlation of the total scores of nurses' affective organizational commitment and work environment conditions indicated a significant and positive relationship. Also, a statistically significant relationship was found between affective organizational commitment and life satisfaction. The implementation of a comprehensive program to improve the work conditions and life satisfaction of nurses could enhance their organizational commitment.

    Employee turnover is a large and expensive problem in the long-term care environment. Stated intention to leave is a reliable indicator of likely turnover, but actual predictors, especially for nursing assistants, have been incompletely investigated. This quantitative study identifies the relationships among employees' working conditions, mental health, and intention to leave. Self-administered questionnaires were collected with 1,589 employees in 18 for-profit nursing homes. A working condition index for the number of beneficial job features was constructed. Poisson regression modeling found that employees who reported four positive features were 77% less likely to state strong intention to leave (PR = 0.23, p employee mental health. Effective workplace intervention programs must address work organization features to reduce employee intention to leave. Healthy workplaces should build better interpersonal relationships, show respect for employee work, and involve employees in decision-making processes.

    Theories of psychosocial working conditions assume an interaction of different work environment characteristics. Most studies detail various aspects of such interactions, while fewer investigate the comprehensive patterns of interrelated variables. This exploratory study distinguishes patterns of psychosocial working conditions, describes their characteristics, and investigates their change over 6 years. The working conditions of 1,744 high-skilled workers in Sweden, of a representative sample of the working population, were empirically classified into 4 distinct patterns: (a) the Supporting pattern with a very low workload, very low time pressure, medium learning opportunities, high creativity requirements, and very high autonomy; (b) the Constraining pattern with a very low workload, very low time pressure, low learning opportunities, medium creativity requirements, and very low autonomy; (c) the Demanding pattern with a high workload, high time pressure, medium learning opportunities, high creativity requirements, and very low autonomy; and (d) the Challenging pattern with a high workload, high time pressure, very high learning opportunities, very high creativity requirements, and very high autonomy. Importantly, these patterns were associated with significant differences in worker well-being. From an individual perspective, working conditions most often changed from patterns with a high workload and time pressure to patterns with lower levels of these demands. Over time, the prevalence of the Constraining pattern increased while that of the Challenging pattern decreased. To conclude, a person-centered approach broadens the understanding of the complex interplay between psychosocial working conditions and their longitudinal change, which can improve the tailoring of occupational health interventions.

  19. Second-order conditioning and conditioned inhibition: influences of speed versus accuracy on human causal learning.

    Directory of Open Access Journals (Sweden)

    Jessica C Lee

    Full Text Available In human causal learning, excitatory and inhibitory learning effects can sometimes be found in the same paradigm by altering the learning conditions. This study aims to explore whether learning in the feature negative paradigm can be dissociated by emphasising speed over accuracy. In two causal learning experiments, participants were given a feature negative discrimination in which the outcome caused by one cue was prevented by the addition of another. Participants completed training trials either in a self-paced fashion with instructions emphasising accuracy, or under strict time constraints with instructions emphasising speed. Using summation tests in which the preventative cue was paired with another causal cue, participants in the accuracy groups correctly rated the preventative cue as if it reduced the probability of the outcome. However, participants in the speed groups rated the preventative cue as if it increased the probability of the outcome. In Experiment 1, both speed and accuracy groups later judged the same cue to be preventative in a reasoned inference task. Experiment 2 failed to find evidence of similar dissociations in retrospective revaluation (release from overshadowing vs. mediated extinction or learning about a redundant cue (blocking vs. augmentation. However in the same experiment, the tendency for the accuracy group to show conditioned inhibition and the speed group to show second-order conditioning was consistent even across sub-sets of the speed and accuracy groups with equivalent accuracy in training, suggesting that second-order conditioning is not merely a consequence of poorer acquisition. This dissociation mirrors the trade-off between second-order conditioning and conditioned inhibition observed in animal conditioning when training is extended.

  20. Researchers´ perceptions on their health and working conditions in Antioquia, Colombia

    Silvia P. Díaz M

    Full Text Available Objective: to analyze how male and female scientific researchers working at public and private universities in Antioquia (Colombia perceive their health and working conditions. Methodology: a qualitative study conducted through interviews and a literature review. Participants belonged to research groups classified as A1, A, and B, according to the standards issued by Colciencias (Colombia’s national Department of Science, Technology and Innovation. Results: researchers perceive the relationship between their work and health as a blend of work-related demands, challenges, and personal and collective rewards. Demands on intellectual productivity are high; there is a mismatch between the actual time devoted to work and the time established in the work plans negotiated with the administration for every semester. In some points of the research process, these factors overload the daily work schedules, thus causing physical pain, stress, and malaise. Nevertheless, researchers find their work worthy because of the passion that research arouses in them. Discussion: The high demands defined within the framework of the National System for Science and Technology (Spanish acronym: SNCT have created a field in which intellectual productivity takes priority over the researchers’ health conditions.

    Full Text Available Abstract Background This research examines the specific contribution of occupation and work organization conditions to alcohol use and misuse. It is based on a social-action model that takes into account agent personality, structures of daily life, and macro social structures. Methods Data come from a representative sample of 10,155 workers in Quebec, Canada. Multinomial regression models corrected for sample design effect have been used to predict low-risk and high-risk drinking compared to non-drinkers. The contribution of occupation and work organization conditions (skill used, decision authority, physical and psychological demands, hours worked, irregular work schedule, harassment, unionization, job insecurity, performance pay, prestige have been adjusted for family situation, social network outside the workplace, and individual characteristics. Results Compared to non-qualified blue-collars, both low-risk and high-risk drinking are associated with qualified blue-collars, semi-qualified white-collars, and middle managers; high-risk drinking is associated with upper managers. For constraints-resources related to work organization conditions, only workplace harassment is an important determinant of both low-risk and high-risk drinking, but it is modestly moderated by occupation. Family situation, social support outside work, and personal characteristics of individuals are also associated with alcohol use and misuse. Non-work factors mediated/suppressed the role of occupation and work organization conditions. Conclusion Occupation and workplace harassment are important factors associated with alcohol use and misuse. The results support the theoretical model conceptualizing alcohol use and misuse as being the product of stress caused by constraints and resources brought to bear simultaneously by agent personality, structures of daily life, and macro social structures. Occupational alcohol researchers must expand their theoretical perspectives to

    The purpose of the study being reported here was to investigate the relationship of job burnout and work engagement with self-reported received treatment for health conditions (cardiovascular condition, high cholesterol, depression, diabetes, hypertension and irritable bowel syndrome), while controlling for age, gender, smoking and alcohol use. The sample comprised 7895 employees from a broad range of economic sectors in the South African working population. A cross-sectional survey design was used for the study. Structural equation modelling methods were implemented with a weighted least squares approach. The results showed that job burnout had a positive relationship with self-reported received treatment for depression, diabetes, hypertension and irritable bowel syndrome. Work engagement did not have any significant negative or positive relationships with the treatment for these health conditions. The results of this study make stakeholders aware of the relationship between job burnout, work engagement and self-reported treatment for health conditions. Evidence for increased reporting of treatment for ill-health conditions due to burnout was found. Therefore, attempts should be made to manage job burnout to prevent ill-health outcomes.

    expected UCS. Fourth, large electrodermal responders to the CSs exhibited patterns of capacity allocation during the CSs, particularly during the CS+, different from those of small electrodermal responders. In particular, they exhibited significantly longer RTs at 300 msec after CS+ onset than did the small responders, followed by a shortening of RT at 500 msec relative to the small responders. This finding suggests that large electrodermal responders devote greater processing capacity to significant environmental stimuli than do small responders and that their processing may begin and be completed more rapidly. All in all, the data indicate the complexity of the cognitive processes that occur during human classical conditioning and the usefulness of the secondary-task technique in integrating conditioning theories and psychophysiology with cognitive psychology.

  5. The Cabin Crew Blues. Middle-aged Cabin Attendants and Their Working Conditions

    2015-12-01

    Full Text Available This article examines how an airline company uses the labor of a group of middle-aged cabin attendants in an industry increasingly characterized by deregulation and competiveness. The study was based on in-depth interviews with seven women, all with between 24 and 30 years of work experience as cabin attendants. The article focuses on the women’s working conditions and well-being and the analysis reveals three key aspects—intensification of work, vulnerability, and aging—that affect the cabin attendants’ experiences and emotions in relation to the work. It is at the intersection of these three aspects that the cabin attendants’ concerns must be understood. The study’s findings indicated that positive emotions such as job satisfaction and commitment have diminished because of exploitative and otherwise poor working conditions. Taking the cabin attendants’ concerns as its point of departure, the article shows that there is a need to move away from a discussion about emotional labor toward a discussion of working conditions.

    Full Text Available OBJECTIVE: To assess the association between exposure to adverse psychosocial working conditions and poor self-rated health among bank employees. METHODS: A cross-sectional study including a sample of 2,054 employees of a government bank was conducted in 2008. Self-rated health was assessed by a single question: "In general, would you say your health is (...." Exposure to adverse psychosocial working conditions was evaluated by the effort-reward imbalance model and the demand-control model. Information on other independent variables was obtained through a self-administered semi-structured questionnaire. A multiple logistic regression analysis was performed and odds ratio calculated to assess independent associations between adverse psychosocial working conditions and poor self-rated health. RESULTS: The overall prevalence of poor self-rated health was 9%, with no significant gender difference. Exposure to high demand and low control environment at work was associated with poor self-rated health. Employees with high effort-reward imbalance and overcommitment also reported poor self-rated health, with a dose-response relationship. Social support at work was inversely related to poor self-rated health, with a dose-response relationship. CONCLUSIONS: Exposure to adverse psychosocial work factors assessed based on the effort-reward imbalance model and the demand-control model is independently associated with poor self-rated health among the workers studied.

    Full Text Available Nicolás Guillén poetry is able to sound out the human and its condition. Besides, it portrays witnessed social phenomena. Thus, it is said that poetry leads to an ethical reflection on the human condition in the world. Hence, it has got a two-sided essence. First, as reasoning set depicting the daily horror and violence an individual deals with. Then, a significant and virtuous narrative that may lead to conceive better ways to inhabit the world. This paper analyzes three main Latin American philosophy topics in Nicolás Guillén works: the human deterioration amidst social, politic and economic conflicts, justice need and human reinvidication claimed by each conflict actor and the importance of listening to other narratives presenting ways to cope with horror and abolish it. In general, this article shows one of the results got by the research group: “Ethics and Literature: Narratives on the human. Nicolás Guillén poetry has images that can be useful for Ethics to enquire inhuman actions. It also holds utopian proposals to build up a fair society and ethic criteria concerning more human action and judgement.

    To estimate the importance of the working environment in sickness absence, as well as to show possible relationships with clinical-work variables. A descriptive observational study. SITE: Medical Inspection of an Andalusian province. A total of 1016 workers on certified sick leave due to a common illness. A self-report questionnaire was used to collect demographic data, profession, activity, risk assessment, and perceived occupational cause, on patients who voluntarily gave their consent when they were reviewed during 2015. The illness that caused certified sickness absences was verified in the computerised medical records. Using criteria applied by experts, the role of working conditions in each episode of certified sick leave was assessed. Bivariate and multivariate analyses were performed to determine any relationships between the variables. An inadequate work environment was found in 17.1% of the sickness processes. Health and hospitality services activities have a significant association with working conditions as a cause of sick leave (P<.001). With respect to diagnosis, anxiety-depressive disorders (P<.01) and low back pain (P<.05) were associated with working conditions. The factors related to certified sickness absence and work environment were: residence (OR=0.34, 0.21-0.6), normal/higher education (OR=1.7, 1.2-2.4), (OR=2.0 1.3-3.1), large companies (OR=1.97, 1.3-2.9), and job (OR=2.7, 1.6-3, 2). Sickness absence is affected by factors related to the work environment. Specific preventive actions for workers at their workplace could reduce work related diseases classified as a common illness.

    2010-06-01

    Evolutionary psychology suggests that certain human beauty standards have evolved to provide reliable cues of fertility and health. Hence, preferences for some physical characteristics of the face and body are thought to reflect adaptations for the promotion of mate choice. Studies that have investigated facial attractiveness have concentrated mainly on features such as symmetry, averageness and sex-typical traits, which are developed under the influence of sex steroids. Few studies, however, have addressed the effect of human skin condition on perception of facial appearance in this context, and possible implications for sexual selection. There is now accumulating evidence that skin pigmentation and skin surface topography cues, particularly in women, have a significant influence on attractiveness judgements, as they seem primarily to signal aspects of age and health. This article (i) reviews briefly some of the main determinants of visible skin condition, (ii) presents recent evidence on its signalling value in face perception and (iii) suggests areas for future research with reference to an evolutionary psychology framework.

    In aviation, there is currently a lack of accurate and timely situational information, specifically weather data, which is essential when dealing with the unpredictable complexities that can arise while flying. For example, weather conditions that require immediate evasive action by the flight crew, such as isolated heavy rain, micro bursts, and atmospheric turbulence, require that the flight crew receive near real-time and precise information about the type, position, and intensity of those conditions. Human factors issues arise in considering how to display the various sources of weather information to the users of that information and how to integrate this display into the existing environment. In designing weather information display systems, it is necessary to meet the demands of different users, which requires an examination of the way in which the users process and use weather information. Using Human Centered Design methodologies and concepts will result in a safer, more efficient and more intuitive solution. Specific goals of this approach include 1) Enabling better fuel planning; 2) Allowing better divert strategies; 3) Ensuring pilots, navigators, dispatchers and mission planners are referencing weather from the same sources; 4) Improving aircrew awareness of aviation hazards such as turbulence, icing, hail and convective activity; 5) Addressing inconsistent availability of hazard forecasts outside the United States Air Defense Identification Zone (ADIZ); and 6) Promoting goal driven approaches versus event driven (prediction).

    The working conditions and the prevalence of self-reported musculoskeletal symptoms among 180 Iranian hand-sewn shoe workers were evaluated in this cross-sectional study. Data were collected using both questionnaire (for assessing musculoskeletal symptoms and associated risk factors) and direct observations of posture (by the Rapid Upper Limb Assessment [RULA] method). The prevalence and severity of symptoms was very high among the study population. The mean RULA grand score of 6.2 indicates that in most cases the workers' postures at their workstations need to be investigated and some changes are required immediately. Multiple logistic regression models indicated that the job experience, daily working hours, duration of continuous work without breaks, feeling pressure due to work and working postures were significantly associated with musculoskeletal symptoms of different body regions. The results are discussed in terms of their implications for hand-sewing tasks. These findings can help to better understand the working conditions of those jobs involving hand-sewing operation and highlight the potential for ergonomic interventions to reduce musculoskeletal symptoms among these working groups.

    In recent years, the role of pharmacists has changed, as have various provincial legislations, which now allow pharmacists to provide additional health services to patients. With these changes comes growing concern about how well the current pharmacy working environment is adapting and whether it may also be creating work-related stress that may contribute to potentially unsafe practices of patient care. To characterize the current working conditions of pharmacists in British Columbia, an online survey was developed and distributed to all College of Pharmacists of BC (CPBC) registrants by email. The survey consisted of questions on pharmacists' demographics, practice setting and perceptions of workplace conditions. Responses were collected from October 1 to November 10, 2013. All data were summarized using descriptive statistics, and regression models were constructed to assess the association between various factors and pharmacists' self-reported working conditions. Twenty-three percent (1241/5300) of pharmacists registered with the CPBC responded, with 78% working in the community pharmacy setting (58% chain, 19% independent). Pharmacists mostly disagreed with the statements that they had enough time for breaks or lunches or to do their jobs, as well as enough staffing support. Pharmacists' perceptions of their workplace environment were negatively associated with workplace-imposed advanced service quotas (for medication reviews, immunizations and prescription adaptations); being employed at chain store pharmacies, compared to independent pharmacies or hospitals/long-term care settings; and higher prescription volume. Pharmacists working in chain community pharmacies who are required to meet monthly quotas for expanded services reported a substantial negative impact on their working conditions and perceived safety of patient care.

    In the adult human, the kidney is the main organ for the production and release of erythropoietin (EPO). EPO is stimulating erythropoiesis by increasing the proliferation, differentiation and maturation of the erythroid precursors. In the last decades, enormous efforts were made in the purification, molecular encoding and description of the EPO gene. This led to an incredible increase in the understanding of the EPO-feedback-regulation loop at a molecular level, especially the oxygen-dependent EPO gene expression, a key function in the regulation loop. However, studies in humans at a systemic level are still very scanty. Therefore, it is the purpose of the present review to report on the main recent investigations on EPO production and release in humans under different environmental and experimental conditions, including: (i) studies on EPO circadian, monthly and even annual variations, (ii) studies in connection with short-, medium- and long-term exercise at sea-level which will be followed (iii) by studies performed at moderate and high altitude.

    High-power (HP) UV-LEDs can replace UV lamps for real-time fluoro-sensing applications by allowing portable and autonomous systems. However, HP UV-LEDs are not a mature technology, and there are still open issues regarding their performance evolution over time. This paper presents a reliability study of 3 W UV-LEDs, with special focus on LED degradation for two working conditions: continuous and cycled (30 s ON and 30 s OFF). Accelerated life tests are developed to evaluate the influence of temperature and electrical working conditions in high-power LEDs degradation, being the predominant failure mechanism the degradation of the package. An analysis that includes dynamic thermal and optical HP UV-LED measurements has been performed. Static thermal and stress simulation analysis with the finite element method (FEM) identifies the causes of package degradation. Accelerated life test results prove that HP UV-LEDs working in cycled condition have a better performance than those working in continuous condition.

    Anita B. Varkey MD

    2016-02-01

    Full Text Available Objectives: To determine whether workplace conditions affect care quality and errors, especially in primary care clinics serving minority patients. Methods: We conducted a 3-year assessment of work conditions and patient outcomes in 73 primary care clinics in the upper Midwest and New York City. Study participants included 287 physicians and 1204 patients with hypertension and/or diabetes. Chart audit data were contrasted between clinics with ≥30% minority patients (minority-serving clinics, or MSCs and those with <30% (nonminority-serving clinics, or NMSCs. Physicians reported on time pressure, work control, clinical resources, and specialty referral access; managers described room availability; and chart audits determined care errors and quality. Two-level hierarchical models tested work conditions as mediators between MSC status and clinical outcomes. Results: Error rates were higher in MSCs than NMSCs (29.6% vs 24.8%, P < .05. Lack of clinical resources explained 41% of the effect of MSC status on errors (P < .05. Diabetes control was poorer in MSCs than in NMSCs (53.8% controlled vs 76.1%, P < .05; lack of clinical resources explained 24% of this difference (P < .05. Room availability increased quality in both MSCs and NMSCs by 5.95% for each additional room per clinician per session. Lack of access to rooms and specialists decreased the likelihood of blood pressure control in MSCs. Conclusion: Work conditions such as clinical resources, examination room availability, and access to referrals are significantly associated with errors and quality, especially in MSCs.

    2012-01-01

    Background: Carpet weaving operations usualy involve poor working conditions that can lead to the development of musculoskeletal disorders (MSDs). This study investigated MSDs among car¬pet weavers in relation to working conditions from workers' view in Tabriz City, Northwest Iran. Methods: This cross-sectional and descriptive study was conducted in city of Tabriz, Iran. Data were col¬lected using interviews and questionnaires. The study population consisted of 200 randomly selected healthy weavers from twenty five active carpet weaving workshops. Results: The results showed a high prevalence of musculoskeletal problems among the study population. The most commonly affected body areas were neck, lower back, ankles/feet, hands/wrists, upper back, shoulders and knees, respectively. More than half of the weavers were not satisfied with the thermal con¬dition, noise level and cleanliness of the air in the workshops. The result indicated a significant relation¬ship between upper back symptoms and daily working time and between lower back symptoms and the numbers of rows of knots woven in a day. Weavers' satisfaction with hand tools shape and thermal condi¬tion of the workshops were associated with lower back symptoms, whereas satisfaction with weaving looms were associated with upper back complaints. Conclusion: The poor working condition of hand-woven carpet workshops such as environmental con¬ditions and work station design and tools should be the subject of ergonomics interventions.

    To extend a standard paradigm of conditioning in nonhumans to humans, we created a virtual reality (VR) conditioned place preference task, with real-life food rewards. Undergraduates were placed into a VR environment consisting of 2 visually distinct rooms. On Day 1, participants underwent 6 pairing sessions in which they were confined into one of the two rooms and explored the VR environment. Room A was paired with real-life M&Ms for 3 sessions, and Room B was paired with no food for 3 sessions. Day 2 was the test day, administered the next day, and participants were given free access to the entire VR environment for 5min. In experiment 1, participants were food restricted, and we observed that on the test day, participants display a significant conditioned place preference for the VR room previously paired with food (pFuture research will examine the extent to which these preferences can be blocked or extinguished as well as whether these preferences are evident using other reinforcers.

  7. [Conditions for going back to work on a part-time basis as a therapeutic objective].

    Science.gov (United States)

    Manaouil, Cécile; Graser, Marie; Jardé, Olivier

    2003-07-12

    AFTER MEDICAL ASSESSMENT: In the general system, therapeutic part-time work is a temporary disposition which allows a progressive readaptation to work. In principle, when an employee goes back to work, daily sickness benefits stop being paid by the Social Security Service. The decision to go back to work on a part-time basis is conditioned by a preliminary medical estimation which justifies the fact that it is impossible for the patient to go on with his professional occupation on a full-time basis or which shows the need for a progressive resumption. THE ATTENDING PHYSICIAN: During the part-time resumption, he has to continue to fill-out the sick leave certificates and add the comment "part-time work resumption". After an industrial accident or an occupational disease (work stoppage/occupational disease), on the extension medical certificate, the doctor should check the "work resumption" box, and add "therapeutic part-time job". The doctor should not produce a final medical certificate but only extension certificates. A part-time work resumption cannot be prescribed after the consolidation date, which stops the payment of the daily sickness benefits granted for a work disease. THE ROLE OF THE EMPLOYER: In principle, the employer has to subject the employee to a work resumption medical consultation by the company doctor. If a medical control authorization from the Social Security and the ability certificate for the part-time work resumption provided by the company doctor are produced, the employee has to be employed on a part-time basis by the employer, excepting when this is not compatible with the firm's activity. CIVIL SERVICE: Part-time work resumption is a therapeutic part-time job (50% only), and cannot follow after an ordinary sick leave. Its allocation depends on the medial committee decision after a long sick leave, or the reform commission decision after an industrial accident or an occupational disease.

    2015-01-01

    The aim of this study was to clarify the relationship between self-awareness of fatigue symptoms and working conditions, in female nurses. We studied personal background, working conditions, physical symptoms, "Pittsburgh Sleep Quality Index - Japanese version (PSQI-J)", and 13 items that represented the parts related to self-awareness of the "the self-Diagnosis Checklist for Workers' Accumulated Fatigue" in 3,855 female nurses. The targets for analysis were 983 nurses ("all subjects") and among those, 765 "shift workers". The total score (fatigue symptoms self-awareness score) was calculated for 13 items that represented the parts related to self-awareness of the "the self-Diagnosis Checklist for Workers' Accumulated Fatigue". The Mann-Whitney U test and the Kruskal-Wallis test were performed, and the fatigue symptoms self-awareness score was studied, based on personal background, working conditions, physical symptoms and the PSQI-J score. For "all subjects", there was a significant difference in the fatigue symptoms self-awareness score for department in which they work, the form the work takes, and the PSQI-J score. The fatigue symptoms self-awareness score of nurses with a PSQI-J score of 5.5 or higher was a significantly high value. For "shift workers", there was a significant difference in the fatigue symptoms self-awareness score for presence or absence of a caregiver role, department in which they work, the form the work takes, the form the nap takes during night work and PSQI-J score. There was a significantly high value in the fatigue symptoms self-awareness score of subjects with a caregiver role, subjects working in surgical wards or internal medicine wards, subjects working on a three-shift system, and subjects who were unable to take naps during night work, subjects with a PSQI-J score of 5.5 or higher. These survey results suggest that it is important to set up a system that will ensure the ability to have naps during night work. It will also be

    The objective of this study is to investigate whether sleep problems might account for the increased working memory deficits observed in school-aged children with neurological conditions. A novel, transdiagnostic approach to the investigation was chosen, and sleep is treated as a process that can potentially account for working memory difficulties across a range of neurological conditions. Prevalence estimates of sleep problems are also examined. Archival data of 237 children aged 6 to 11 years were collected from a Western Australian statewide neuropsychological service for the period 26 July 2011 to 14 January 2014. Measures of parent-reported sleep quality, snoring, and daytime sleepiness were obtained, in addition to objective measures of verbal and spatial working memory, storage capacity, and processing speed. The results of the data analysis reveal that over one third of participants reported having clinically-significant levels of sleep problems and that poor sleep quality is significantly associated with verbal working memory difficulties. This association remains after partialling out the variance contributed to performance by storage capacity and processing speed, suggesting that sleep is impacting upon an executive component of working memory. No other significant associations are observed. The results suggest that poor sleep quality is associated with an executive component of verbal (rather than spatial) working memory in children with neurological conditions. This has implications for the biological mechanisms thought to underlie the relationship between sleep and cognition in children. The results also demonstrate the clinical utility of a transdiagnostic approach when investigating sleep and cognition in children with neurological conditions.

  10. Social responsibility and work conditions: building a reference label, Démarche T®.

    Biquand, Sylvain; Zittel, Benoit

    2012-01-01

    Corporate Social Responsibility (CSR) is now considered in large and global companies and the recent publication of the ISO 26000 standard clarifies the targets. Based on our consultancy's experience for fifteen years in ergonomics mainly in French small and medium enterprises, we developed a label to coax and value efforts of companies in dealing with health and safety at the work place as required by ISO 26000 paragraph 6.4. The formal approach of ISO describes what should be achieved but gives no cue on how actual conditions of work should be improved. The label, called Démarche T (ie Process W where W stands for work) aims the management of work conditions as a process, giving visibility and credit to companies for their continuous involvement in the matter. We describe the items and processes that are part of our assessment. We first conduct an ergonomic diagnosis including the analysis of records on health, physical and psychological well-being, observations at the workplace and interviews with the workers. This diagnosis is followed by recommendations. The fulfillment of these is assessed yearly. Items under assessment include: - ergonomics, health and safety in the companies statements and their impact in actual project management; - relations with workers through the committee for health and safety; - actual results on health, safety and work conditions. On a local level, we give the companies passing the label a competitive edge in recruiting better candidates motivated by good work conditions, and help them fulfill ISO 26000 requirements, an increasingly decisive advantage to benefit from public regional and European support. Our paper describes the diagnosis and follow-up process.

    Sarka Sustova

    2013-03-01

    Full Text Available The main aim of the article is to analyse the working poor employees and their household's social situation in the national income and living conditions survey (EU-SILC. The analysis starts with the definition of the two main groups of employees according to the number of months spent in the full-time employment - those working whole year and those employed for 6 to 11 months. Poverty in earned income concept is used to evaluate poverty at individual level, confronting employee's income with single person household poverty line benchmark. The study then moves to the household level poverty measure based on household's disposable equivalised income. When shifting from the individual income to the household's one the economies of scale represented by an implicit or explicit equivalence scale used in the construction of the household poverty measure play a crucial role. Therefore, attention is paid to the comparison of poverty level based on equivalised disposable income using equivalence scales and per-capita income. At the end, material deprivation of different subgroups of employees according to their poverty status is examined.

  12. Managing Organized Insecurity: The Consequences for Care Workers of Deregulated Working Conditions in Elderly Care

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Part-time work is more than twice as common among women than men in Sweden. New ways of organizing working hours to allow for more full-time jobs have been introduced for care workers in elderly care, which means unscheduled working hours based on the needs of the workplace. The aim of the study is to analyze how the organization of the unscheduled working hours affect employees’ daily lives and their possibility to provide care. The Classic Grounded Theory method was used in a secondary analysis of interviews with employees and managers in Swedish municipal elderly care. The implementation of unscheduled working hours plunged employees into a situation of managing organized insecurity. This main concern for the care workers involved a cyclic process of first having to be available for work because of economic and social obligations to the employer and the co-workers, despite sacrifices in the private sphere. Then, they had to be adaptable in relation to unknown clients and co-workers and to the employer, which means reduced possibilities to provide good care. Full-time jobs were thus created through requiring permanent staff to be flexible, which in effect meant eroded working conditions with high demands on employee adaptability. Solving the part-time problem in elderly care by introducing unscheduled working hours may in effect be counter-productive.

  13. The contributions of Nan Goldin’s photographic work with the formation of a plural humanism

    Full Text Available In the last two centuries the photography in its function to retain the immediately brief and momentary present, has been a central narrator of the human history, not only as a passive narrator of events, but also as an active one, to say it as a tenacious sensitizer of the situation that the human being and its society has lived. The photographic work of Nan Goldin in the investigation group “Ehics, pedagogy and literature” has been assumed as a narrative that thinks about human condition throughout history, as well as a vehicle that goes beyond established limits. In general, we propose that photography is a central element in the humanist formation because it makes the individual thinks about himself in a new way.

    This paper contributes to recent studies exploring the longue durée of human impacts on island landscapes, the impacts of climate and other environmental changes on human communities, and the interaction of human societies and their environments at different spatial and temporal scales. In particular, the paper addresses Iceland during the medieval period (with a secondary, comparative focus on Norse Greenland) and discusses episodes where environmental and climatic changes have appeared to cross key thresholds for agricultural productivity. The paper draws upon international, interdisciplinary research in the North Atlantic region led by the North Atlantic Biocultural Organization (NABO) and the Nordic Network for Interdisciplinary Environmental Studies (NIES) in the Circumpolar Networks program of the Integrated History and Future of People on Earth (IHOPE). By interlinking analyses of historically grounded literature with archaeological studies and environmental science, valuable new perspectives can emerge on how these past societies may have understood and coped with such impacts. As climate and other environmental changes do not operate in isolation, vulnerabilities created by socioeconomic factors also beg consideration. The paper illustrates the benefits of an integrated environmental-studies approach that draws on data, methodologies and analytical tools of environmental humanities, social sciences, and geosciences to better understand long-term human ecodynamics and changing human-landscape-environment interactions through time. One key goal is to apply previously unused data and concerted expertise to illuminate human responses to past changes; a secondary aim is to consider how lessons derived from these cases may be applicable to environmental threats and socioecological risks in the future, especially as understood in light of the New Human Condition, the concept transposed from Hannah Arendt's influential framing of the human condition that is

    Between October 2011 and September 2013, we conducted research on the use, by police and/or prosecutors, of condom possession as evidence of intent to engage in prostitution-related offenses. We studied the practice in five large, geographically diverse cities in the U.S. To facilitate our advocacy on this issue, conducted concurrent to and following our research, we developed an advocacy framework consisting of six dimensions: (1) raising awareness, (2) building and engaging coalitions, (3) framing debate, (4) securing rhetorical commitments, (5) reforming law and policy, and (6) changing practice. Using a case study approach, we describe how this framework also provided a basis for the evaluation of our work, and discuss additional considerations and values related to the measurement and evaluation of human rights advocacy.

  18. Rhythmic Working Memory Activation in the Human Hippocampus

    2015-11-01

    Full Text Available Working memory (WM maintenance is assumed to rely on a single sustained process throughout the entire maintenance period. This assumption, although fundamental, has never been tested. We used intracranial electroencephalography (EEG recordings from the human hippocampus in two independent experiments to investigate the neural dynamics underlying WM maintenance. We observed periodic fluctuations between two different oscillatory regimes: Periods of “memory activation” were reflected by load-dependent alpha power reductions and lower levels of cross-frequency coupling (CFC. They occurred interleaved with periods characterized by load-independent high levels of alpha power and CFC. During memory activation periods, a relevant CFC parameter (load-dependent changes of the peak modulated frequency correlated with individual WM capacity. Fluctuations between these two periods predicted successful performance and were locked to the phase of endogenous delta oscillations. These results show that hippocampal maintenance is a dynamic rather than constant process and depends critically on a hierarchy of oscillations.

  20. Working the Night Shift: The Impact of Compensating Wages and Local Economic Conditions on Shift Choice

    Directory of Open Access Journals (Sweden)

    Colene Trent

    2014-01-01

    Full Text Available The theory of compensating differentials asserts that night shift workers should receive compensating wage differentials due to undesirable work conditions. In weak local economies, workers may have difficulty finding jobs; thus, these workers might be more likely to accept night shift work and be less concerned with the size of the compensating differential for night shifts. Using CPS data from 2001, this paper employs maximum likelihood estimation of an endogenous switching regression model to analyze wages of day and night shift workers and shift choice. The findings indicate the presence of selection bias, thus emphasizing the importance of correcting for self-selection into night shifts. The average of the estimated wage differentials for night shift work is negative for the overall sample, with differentials varying by worker characteristics. The shift differential is found to be a statistically significant predictor of shift choice, indicating that shift premiums play an important role in motivating individuals to select night shift work. Using two measures of local economic conditions and a new method of analyzing interaction effects in the context of an endogenous switching regression model, this paper finds limited evidence that weak local economic conditions lessen the impact of compensating differentials on shift choice.

    There was carried out a hygienic assessment of the working conditions and health of employees of the "Siberian Lift Co., Ltd.". When studying occupational factors on workplaces intensity, the temperature radiation, natural and artificial lighting, and also the content of chemicals they were revealed to fail to answer to the hygienic specifications. It is established that in 82% of employees the class of working conditions was detected as admissible (2) and in 18%--harmful (3.1 and 3.2). Results of the performed periodic medical examination of employees of the "Siberian Lift Co., Ltd.". It is testified that 6.14% out of them are persistently unfit of the work with harmful and (or) dangerous substances and occupational factors also. 4.68% of employees demand an additional examination. 11,70% of workers need for out-patient examination and treatment. Sanatorium treatment is required for 1 (0.29%) the person. 4,68% of employees of the "Siberian Lift Co., Ltd." need dispensary supervision. There are suggested measures for the improvement of working conditions and health of the employees.

  2. Temperature dependence of the work function of caesiated materials under ion source conditions

    Friedl, R.; Fantz, U.

    2015-04-01

    The key parameter for the performance of negative hydrogen ion sources based on surface conversion is the work function of the converter surface. In order to enhance the negative ion yield caesium is introduced into the source which lowers the converter work function upon adsorption. However, the Cs layer is subject to background pressures of 10-7-10-6 mbar and to H2 or D2 low-temperature plasmas which can have a major impact on the resultant work function. In order to determine the work function of caesiated surfaces under ion source relevant conditions and to identify influencing parameters, systematic investigations are performed at the laboratory experiment ACCesS. It is confirmed, that the work function of a sample surface in a vacuum of 10-6 mbar is decreased upon the evaporation and adsorption of caesium. However, the adsorbed layer is determined by the formation of Cs compounds with residual gases from the background pressure leading to an increased work function by about 0.6 eV compared to pure Cs layers. Elevated surface temperatures are beneficial for cleaning and against degradation in absence of Cs evaporation, but no further enhancement of the work function can be achieved by temperatures up to 260 °C if a Cs flux onto the surface is already present. Thus, the minimally achievable work function of a stainless steel surface in ion source relevant vacuum conditions is 2.75 eV. The influence of the substrate material and plasma surface interaction will be investigated next.

    Full Text Available This paper discuss about a master’s thesis academicals work. It had as objective to analyze the suffering of nursing workers through the increase of the working hours, of the multi work or the extra scales of work, of the laboring conditions in these workers’ daily lives. The research was developed in a public hospital in Natal/RN. The methodology was led by a descriptive study with a qualitative approach. The technique of information collecting was employed. The individual interviews were guided by a script with open and half-structuralized questions. The period of information collecting corresponds to the months of July and August of 2003. In the analysis of data, the transcribed interviews were organized according to the group it belonged, an exhaustive reading of the texts was realized for the grouping of informations with common characteristics. Each unity of register was being grouped according to empiric categories that arose during the process. The analysis of informations was realized based in elements of the dialectic method. The results of the research lead to: the existence of an emptiness feeling and imbrutement of the affective bows with relatives; conflicts of values concerning the relation of being/having; anxiety and stress caused by impotence feelings in daily work; the feeling of dreams capture and loss as result of the working hours accumulation; recognition of the suffering through a transversal line under the sort optics. It is concluded therefore that the increase of the working hours is bringing to the workers physical and emotional consuming, and the suffering in the daily life is a result of the precariousness of the work conditions. All these factors are generating unsatisfied workers, compromising the given assistance, as well as making it difficult the interpersonal relations into the public and private dimensions of the daily life.

    Teamwork is becoming increasingly common in today's workplaces; however, little research has examined how well teams perform under sleep deprivation conditions. The purpose of the current study was to examine the effect of extended work under sleep deprivation conditions on team performance. A total of 24 participants were sleep deprived for 30 h and completed 16 h of sustained operations during the last portion of the sleep deprivation period. The participants completed the Wombat, a complex task including vigilance and cognitive components, with a partner in four 24-min testing sessions during the sustained operations period. The results indicated that team performance increased during the work period while, within each testing session, team performance on vigilance tasks remained stable and overall performance decreased. The current results suggest that performance on two-person teams results in improved performance but does not fully counteract the decreases in performance within each work period. Performance in two-person teams increased across an extended work shift under sleep deprivation conditions. However, vigilance performance remained stable while overall performance decreased when examining performance in 8-min segments. These results suggest that averaging team-based performance over a longer testing period may mask the negative effects of sleep deprivation. STATEMENT OF RELEVANCE: Performance in two-person teams increased across an extended work shift under sleep deprivation conditions. However, vigilance performance remained stable while overall performance decreased when examining performance in 8-min segments. These results suggest that averaging team-based performance over a longer testing period may mask the negative effects of sleep deprivation.

    Full Text Available We performed hygienic assessment of working conditions at railway transport over 2011–2015. We detected a decreasing trend in specific weight of working places where physical factors were higher than hygienic standards and where steam and gases content in working area air was higher than maximum permissible concentrations (MPC. Working conditions of locomotive teams remain most unfavorable as per risk factors. We detected that a priori occupation risk for locomotive teams was characterized with parameters varying from moderate to considerable ones. Occupational noise was determined as a priority risk factor making working conditions category a hazardous one and it corresponded to occupational morbidity structure. We detected that sensorineural hearing loss took a leading place in morbidity both in the branch in general and among locomotive team workers. We also clarified that such workers as engine drivers and their assistants (up to 43 % had the greatest specific weight among railway workers with occupational diseases; occupational morbidity among locomotive team workers amounted to 3.0 per 10,000 workers in 2015 while average morbidity among all railway workers amounted to only 1.32 per 10,000 workers. We revealed that occupational diseases were most frequently detected in workers aged 51–60 (51.9 % in 2014 who had worked under hazardous occupational factors influence for longer than 15 years. While there was an overall decreasing trend in occupa-tional morbidity in the branch in 2011–2015 from 1.68 to 1.32 per 10,000 workers, we detected a brunch peculiarity in the risk group, namely, an unsatisfactory trend for growing share of workers with occupational diseases aged 31–40 (from 2.6 % in 2011 to 12 % in 2014 and it requires special attention in terms of risk management.

    The moderating role of personality traits between work organization conditions and alcohol misuse by Canadian workers was examined. Longitudinal data came from Statistics Canada's National Population Health Survey (NPHS). Data had a hierarchical structure and were analyzed using multilevel logistic regression models. The multilevel analyis revealed that skill utilisation at work increased by 7% the risk of being part of an alcohol misuse group. Similarly, psychological demands at work, and being confronted with an irregular work schedule increased alcohol misuse respectively by 69 and 611%. Inversely, workers confronted with a job insecurity and those benefitting from social support at work had a respective 12 and 5% lower risk of being part of an alcohol misuse group. As for personnality traits, self-esteem increased by 17% the risk of alcohol misuse, while sense of coherence decreased the risk by 1%. Finally, self-esteem moderated by 3% the impact of physical demands at work on workers'alcohol misuse. This study builds upon previous research, since no prior study was able to identify the moderating role that self-esteem plays between physical demands at work, and worker's alcohol misuse.

    Full Text Available Mental illness is one of the reasons for the great number of absences from work due to incapacity in Brazil. Recently, mental disorders were included in the list of occupational diseases of the International Labour Office. In spite of the difficulty in attributing a causal link between an inappropriate work environment and mental illness, studies have shown that workers exposed to high levels of stress are more likely to present psychopathological symptoms. The present study investigated the relationship between working conditions and the Neuroticism personality factor. Participants were 951 workers from southern Brazilian poultry slaughterhouses, who work in positions with varied levels of risk and stress. The neuroticism scores of such employees were compared with those of other samples. A scale which measures the Neuroticism factor in the model of the Big Five Personality Factor validated for use in Brazil was employed. The results showed that workers of the sectors in which the working conditions are highly stressful presented higher levels in all sub-factors of neuroticism than workers in other sectors and groups. These sectors also showed higher indexes of mental disorders.

    Nurse burnout is a widespread phenomenon characterized by a reduction in nurses' energy that manifests in emotional exhaustion, lack of motivation, and feelings of frustration and may lead to reductions in work efficacy. This study was conducted to assess the level of burnout among Jordanian nurses and to investigate the influence of leader empowering behaviors (LEBs) on nurses' feelings of burnout in an endeavor to improve nursing work outcomes. A cross-sectional and correlational design was used. Leader Empowering Behaviors Scale and the Maslach Burnout Inventory (MBI) were employed to collect data from 407 registered nurses, recruited from 11 hospitals in Jordan. The Jordanian nurses exhibited high levels of burnout as demonstrated by their high scores for Emotional Exhaustion (EE) and Depersonalization (DP) and moderate scores for Personal Accomplishment (PA). Factors related to work conditions, nurses' demographic traits, and LEBs were significantly correlated with the burnout categories. A stepwise regression model-exposed 4 factors predicted EE: hospital type, nurses' work shift, providing autonomy, and fostering participation in decision making. Gender, fostering participation in decision making, and department type were responsible for 5.9% of the DP variance, whereas facilitating goal attainment and nursing experience accounted for 8.3% of the PA variance. This study highlights the importance of the role of nurse leaders in improving work conditions and empowering and motivating nurses to decrease nurses' feelings of burnout, reduce turnover rates, and improve the quality of nursing care.

    The objective of this study is to investigate whether the characteristics of the structure of primary health units and the work process of primary care teams are associated with the number of hospitalizations for primary care sensitive conditions. In this ecological study, we have analyzed data of Brazilian municipalities related to sociodemographic characteristics, coverage of care programs, structure of primary health units, and work process of primary care teams. We have obtained the data from the first cycle of the Brazilian Program for Improving Access and Quality of the Primary Care, of the Department of Information Technology of the Brazilian Unified Health System, the Brazilian Institute of Geography and Statistics, and the United Nations Development Programme. The associations have been estimated using negative binomial regression coefficients (β) and respective 95% confidence intervals, with a hierarchical approach in three levels (alpha = 5%). In the adjusted analysis for the outcome in 2013, in the distal level, the coverage of the Bolsa Família Program (β = -0.001) and private insurance (β = -0.01) had a negative association, and the human development index (β = 1.13), the proportion of older adults (β = 0.05) and children under the age of five (β = 0.05), and the coverage of the Community Health Agent Strategy (β = 0.002) showed positive association with hospitalizations for primary care sensitive conditions. In the intermediate level, minimum hours (β = -0.14) and availability of vaccines (β = -0.16) showed a negative association, and availability of medications showed a positive association (β = 0.16). In the proximal level, only the variable of matrix support (β = 0.10) showed a positive association. The variables in the adjusted analysis of the number of hospitalizations for primary care sensitive conditions in 2014 presented the same association as in 2013.

    This study investigated the specific contribution of occupations and work organization conditions to the onset and recurrent alcohol misuse in Canadian workers between 1994-1995 and 2002-2003. Longitudinal data were derived from Statistics Canada's National Population Health Survey, totaling 6,526 and 6,582 workers (45% females) nested in 1,337 and 1,413 neighborhoods for onset and recurrent alcohol misuse, respectively. Data were analyzed with multilevel logistic regression models. Results suggested a limited contribution for work factors to the onset of alcohol misuse, a stronger influence for them on recurrent alcohol misuse. The study's limitations are discussed.

    Fear conditioning is considered an animal model of post-traumatic stress disorder. Such models have shown fear conditioning disrupts subsequent rapid eye movement sleep (REM). Here, we provide a translation of these models into humans. Using the fear potentiated startle (FPS) procedure, we examined the effects of fear conditioning and safety signal learning on subsequent REM sleep in healthy adults. We also examined the effects of changes in REM sleep on retention of fear and safety learning. Participants (n = 42 normal controls) spent 3 consecutive nights in the laboratory. The first was an adaptation night. Following the second night, we administered a FPS procedure that included pairing a wrist shock with a threat signal and a safety signal never paired with a shock. The next day, we administered the FPS procedure again, with no wrist shocks to any stimulus, to measure retention of fear and safety. Canonical correlations assessed the relationship between FPS response and REM sleep. Results demonstrated that increased safety signal learning during the initial acquisition phase was associated with increased REM sleep consolidation that night, with 28.4% of the variance in increased REM sleep consolidation from baseline accounted for by safety signal learning. Overnight REM sleep was, in turn, related to overnight retention of fear and safety learning, with 22.5% of the variance in startle retention accounted for by REM sleep. These data suggest that sleep difficulties, specifically REM sleep fragmentation, may play a mechanistic role in post-traumatic stress disorder via an influence on safety signal learning and/or threat-safety discrimination.

    Full Text Available BACKGROUND: The effect of storage conditions on the microbiome and metabolite composition of human biological samples has not been thoroughly investigated as a potential source of bias. We evaluated the effect of two common storage conditions used in clinical trials on the bacterial and metabolite composition of the vaginal microbiota using pyrosequencing of barcoded 16S rRNA gene sequencing and (1H-NMR analyses. METHODOLOGY/PRINCIPAL FINDINGS: Eight women were enrolled and four mid-vaginal swabs were collected by a physician from each woman. The samples were either processed immediately, stored at -80°C for 4 weeks or at -20°C for 1 week followed by transfer to -80°C for another 4 weeks prior to analysis. Statistical methods, including Kolmogorovo-Smirnov and Wilcoxon tests, were performed to evaluate the differences in vaginal bacterial community composition and metabolites between samples stored under different conditions. The results showed that there were no significant differences between samples processed immediately after collection or stored for varying durations. (1H-NMR analysis of the small molecule metabolites in vaginal secretions indicated that high levels of lactic acid were associated with Lactobacillus-dominated communities. Relative abundance of lactic acid did not appear to correlate with relative abundance of individual Lactobacillus sp. in this limited sample, although lower levels of lactic acid were observed when L. gasseri was dominant, indicating differences in metabolic output of seemingly similar communities. CONCLUSIONS/SIGNIFICANCE: These findings benefit large-scale, field-based microbiome and metabolomic studies of the vaginal microbiota.

    The purpose of this study was to evaluate the implementation of an Occupational Health and Safety Management Model for informal sector workers in Thailand. The studied model was characterized by participatory approaches to preliminary assessment, observation of informal business practices, group discussion and participation, and the use of environmental measurements and samples. This model consisted of four processes: capacity building, risk analysis, problem solving, and monitoring and control. The participants consisted of four local labor groups from different regions, including wood carving, hand-weaving, artificial flower making, and batik processing workers. The results demonstrated that, as a result of applying the model, the working conditions of the informal sector workers had improved to meet necessary standards. This model encouraged the use of local networks, which led to cooperation within the groups to create appropriate technologies to solve their problems. The authors suggest that this model could effectively be applied elsewhere to improve informal sector working conditions on a broader scale.

  18. Consumer demand as a driver of improved working conditions: the 'Ergo-Brand' proposition.

    Neumann, W Patrick; Dixon, Shane M; Nordvall, Anna-Carin

    2014-01-01

    This article develops and explores the 'Ergo-Brand' proposition, which posits that consumers may prefer to buy goods that are made under good working conditions (GWCs). This preference would enhance a differentiation strategy for companies, thereby fostering the application of ergonomics in production. This proposition is developed in the context of a narrative review of the literature on 'ethical consumerism'. This is supplemented with a survey study, conducted in both Canada and Sweden (n = 141) to explore this proposition. Results indicate that consumers would prefer goods made under GWCs, but not unconditionally as quality and price concerns were ranked higher. Access to information on the working conditions in production was seen as a barrier. Nevertheless, the Ergo-Brand concept may be a viable avenue in promoting attention towards ergonomics in companies - particularly if consumer habits are subject to intervention by advertising. Further research on this strategy is warranted.

    Most research on the work conditions and family responsibilities associated with work-family conflict and other measures of mental health uses the individual employee as the unit of analysis. We argue that work conditions are both individual psychosocial assessments and objective characteristics of the proximal work environment, necessitating multilevel analyses of both individual- and team-level work conditions on mental health. This study uses multilevel data on 748 high-tech professionals in 120 teams to investigate relationships between team- and individual-level job conditions, work-family conflict, and four mental health outcomes (job satisfaction, emotional exhaustion, perceived stress, and psychological distress). We find that work-to-family conflict is socially patterned across teams, as are job satisfaction and emotional exhaustion. Team-level job conditions predict team-level outcomes, while individuals' perceptions of their job conditions are better predictors of individuals' work-to-family conflict and mental health. Work-to-family conflict operates as a partial mediator between job demands and mental health outcomes. Our findings suggest that organizational leaders concerned about presenteeism, sickness absences, and productivity would do well to focus on changing job conditions in ways that reduce job demands and work-to-family conflict in order to promote employees' mental health. We show that both work-to-family conflict and job conditions can be fruitfully framed as team characteristics, shared appraisals held in common by team members. This challenges the framing of work-to-family conflict as a "private trouble" and provides support for work-to-family conflict as a structural mismatch grounded in the social and temporal organization of work.

    In the last few decades, the State of Israel has become a target for work migrants, refugees, asylum seekers and victims of human trafficking, as part of the trend of world immigration. Immigration is a process of loss and change with significant socio-psychological stress, with possible effects on the immigrants' mental health. The Physicians for Human Rights - Israel (PHR) Association operates a psychiatric clinic as part of the Open Clinic for Work Migrants and Refugees. This article will present major clinical issues regarding psychiatry and immigration in Israel according to the data collected at the clinic. Trauma and stress-related psychopathology was found to have a high prevalence in immigrant patients treated at the clinic; prevalence of PTSD (post-traumatic stress disorder) in immigrants was high (23%) and even higher in refugees (33%). Female immigrants are at higher risk for psychiatric hospitalization. The relative rate of African patients at the clinic is significantly higher than patients from other continents. A significant association was found between psychiatric hospitalization and suicide attempts. Immigrant patients present a combination of psychiatric, socio-economic and general medical conditions, which demands a holistic view of the patient. The evaluation of an immigrant patient must take into account the stress related to immigration, gender, culture of origin and the risk for suicide and hospitalization. Treatment recommendations include awareness of cultural diversities, acquiring information regarding the pre-immigration history, preferably using cultural consultants with background in the immigrants' culture and community. Decision-making about medication and diagnostic evaluation should be as inexpensive as possible. Basic human needs (food, shelter) and family support should be included in the decisions about treatment.

    As in other surgical specialties, increasing concern has been expressed worldwide about the shortage of trainees in pediatric surgery training programs. We performed a nationwide survey to investigate the current situation in Germany. An internet-based nationwide survey comprising 36 questions on training conditions in pediatric surgery was linked to the homepage of the German Society of Pediatric Surgery from June to September 2008. Statements on the following aspects were evaluated by responding residents using a scale from 1 (I do not agree at all) to 5 (I fully agree): workplace, cooperation with colleagues, head of the department, cooperation with other specialties, training and research conditions. A median value of 3 indicated an unsatisfactory assessment, with at least 50% of respondents giving an indifferent or negative response. 70 questionnaires were completed. Some of the evaluations revealed problematic areas. In particular, statements regarding working hours revealed dissatisfaction among the responding doctors. The median value accorded the statement "I am satisfied with the current working time regulation" was 2.9. With regard to departmental heads, some criticisms were directed against a perceived lack of soft skills. According to the respondents, their involvement in decision-making processes was insufficient ("We are involved in decision-making processes affecting our working conditions" - median value 2.4). Residents were also dissatisfied with the feedback they received for their work ("I get enough feedback regarding my achievement" - median value 2.6). Another problem area was career development ("I will finish my specialist training in time" - median value 2.9). However, these points did not affect overall satisfaction. Trainee satisfaction with regulations on working hours is low. Despite a general satisfaction with all fields appraised, improvements in various individual areas, e. g., the attitude of departmental heads and strategies of

    To analyse the working conditions of physicians in outpatient clinics adjacent to pharmacies (CAFs) and their organizational elements from their own perspective. We carried out an exploratory qualitative study. Semi-structured interviews were conducted with 32 CAF physicians in Mexico City. A directed content analysis technique was used based on previously built and emerging codes which were related to the experience of the subjects in their work. Respondents perceive that work in CAFs does not meet professional expectations due to low pay, informality in the recruitment process and the absence of minimum labour guarantees. This prevents them from enjoying the benefits associated with formal employment, and sustains their desire to work in CAF only temporarily. They believe that economic incentives related to number of consultations, procedures and sales attained by the pharmacy allow them to increase their income without influencing their prescriptive behaviour. They express that the monitoring systems and pressure exerted on CAFs seek to affect their autonomy, pushing them to enhance the sales of medicines in the pharmacy. Physicians working in CAFs face a difficult employment situation. The managerial elements used to induce prescription and enhance pharmacy sales create a work environment that generates challenges for regulation and underlines the need to monitor the services provided at these clinics and the possible risk for users.

    Lighting in the working environment plays a significant role on the degree of degradation of photosensitive, thermolabile compounds and on working efficiency. Light emitting diodes (LEDs) are semiconductor light emitting devices that are promising artificial light sources with easy modulation of light wave signals and are also known for low heat generation. Therefore, the effect of polychromatic LED light was tested in the working environment using the drug compounds montelukast, nifedipine, and clavulanic acid, which are known to be photosensitive or thermolabile. As a control, other lighting sources like a sodium lamp, a classic (incandescent, tungsten) lamp, and indirect sunlight were also used in this study. All the experiments were carried out with methanolic solutions at room temperature. An Acquity UPLC/MS/MS system was used for quantification of the main analytes and degradation products. Under the tested conditions, LED lighting proved to be more suitable for handling photosensitive and thermolabile compounds.

    Career satisfaction level, degree of mental distress associated with certain work-related factors, and demographics were examined for the first time in obstetricians and gynecologists in Japan. Associations between the score on Kessler 6 screening scale, or the job satisfaction level, and the scores on the job content questionnaire, Social Support Questionnaire (SSQ), working conditions and demographics were examined in 1301 members of the Japan Society of Obstetrics and Gynecology. 8.4% of respondents were speculated to suffer from depression or anxiety disorder. Multivariate linear regression analysis identified a heavier workload, less personal control, lower satisfaction on the SSQ, and longer working hours as being independent risk factors for mental distress. Careful monitoring of the mental state is necessary for obstetricians and gynecologists with lower incomes, heavier workloads, lower degrees of personal control, and lower satisfaction scores on the SSQ. © 2012 The Authors.

    Full Text Available Analytical characteristics of a biosensor based on glucose oxidase and hexokinase and intended for ATP determination were studied. Platinum disc electrodes were used as amperometric transducers. Range of working potentials for biosensor functioning was shown. An optimal time of enzymes immobilization was determined. Optimal conditions for biosensor functioning during work with biological fluids were selected. Biosensor work in three buffer solutions (PBS, tris and HEPES was investigated and it was shown that it was possible to obtain various operational characteristics of the biosensor depending on tasks that are assigned to it by varying the composition of sample. Reproducibility of biosensor responses to ATP and glucose during a day and of biosensor preparation was shown. The proposed biosensor can be further used for analysis of glucose and ATP content in water solutions.

    Over one million women are employed in child care and are among the lowest wage workers in the US. The health and working conditions of 674 child care workers (118 administrators and 556 staff) from 74 centers is described using baseline data from a larger intervention trial. Participants were 39.9 (±13.0) years old; 55.4% African American, 37.1% Caucasian, and 5.3% of Hispanic ethnicity. Seventy-six percent reported having an Associate's degree or less; 42% were classified as at or below poverty (income and job category. Lower income participants were significantly more likely to be current smokers (19.9% vs. 11.7%), drink more sweetened beverages (1.9 vs. 1.5), and report higher depressive symptoms (15.5 vs. 12.6). Administrators worked more hours weekly compared to staff (46.4 vs. 40.6), are less active (100 vs. 126 min/week), more sedentary (501 vs. 477 min/day), and reported higher job demands (13.3 vs. 12.5). Given the numerous health issues and challenging work conditions, we hope our results serve as a call to action for addressing low wages and the work environment as a means of influencing the health and well-being of child care workers.

    Wellness and prevention strategies are fast becoming a standard feature of employer-based health benefits in hopes of countering rapidly rising health care costs that drive higher insurance premiums. At the same time, payers and health care providers are experimenting with how to improve care coordination for high-cost patients with multiple chronic conditions, an ongoing challenge in the fragmented U.S. health care system. Promoting health and wellness and improving the care of people with chronic conditions offer promise in helping to improve the value of health care and control costs, according to experts at a Center for Studying Health System Change (HSC) conference titled, Innovations in Preventing and Managing Chronic Conditions: What's Working in the Real World? Panelists explored how effective employer-sponsored wellness and prevention initiatives focus on health improvement as a business strategy and foster work and community environments that help people lower risk factors--smoking, diet, lack of exercise--that lead to disease. Panelists also discussed various models--centered on strong primary care-to improve care for people with chronic conditions.

    The aim was to describe and compare nursing assistants', enrolled nurses' and registered nurses' perceptions of quality of care, working conditions, competence and personal health in older peoples' care. Altogether 70 nursing assistants, 163 enrolled nurses and 198 registered nurses completed a questionnaire comprising Quality from the Patient's Perspective modified for caregivers, Creative Climate Questionnaire, Stress of Conscience Questionnaire, items on education and competence and Health Index. The caregivers reported higher perceived reality of quality of care in medical-technical competence and physical-technical conditions than in identity-oriented approach and socio-cultural atmosphere. In subjective importance, the highest rating was assessed in one of the physical-technical items. The organisational climate was for three of the dimensions rather close/reached the value for a creative climate, for seven dimensions close to a stagnant climate. In perceived stress of conscience, there were low values. Nursing assistants had lower values than enrolled nurses and registered nurses. The caregivers reported highest values regarding previous education making them feel safe at work and lowest value on the item about education increasing the ability for a scientific attitude. Registered nurses could use knowledge in practice and to a higher degree than nursing assistants/enrolled nurses reported a need to gain knowledge, but the latter more often received education during working hours. The health index among caregivers was high, but registered nurses scored lower on emotional well-being than nursing assistants/enrolled nurses. The caregivers' different perceptions of quality of care and work climate need further attention. Although stress of conscience was low, it is important to acknowledge what affected the caregivers work in a negative way. Attention should be paid to the greater need for competence development among registered nurses during working hours.

    The New Human Condition (NHC) is perhaps the largest cognitive challenge in history to human intelligence and agency and concerns our species' ability to cope with the consequences and responsibilities of being the major driver of planetary change in the twenty-first century (Pálsson et al., 2013; Holm et al., 2015). But despite long held assumptions about intra-disciplinary engagements between its "human" and "physical" branches, geography's weakness as a discipline is that it has yet to gather sufficient momentum to collectively shape and implement practical and sustainable climate change policies and actions (Castree, 2014a). However, by considering together the heuristic values of the concepts of the Anthropocene and Planetary Boundaries, the Anglo-American sphere of geography recognizes in either ironic, or unconscious manners that a new strand of environmental determinism (discredited by geographical thought and practice in the early twentieth century) has re-emerged to elide the role of human agency and broadly dominate the discussion of climate change. Mike Hulme (2011, 247) states that "climate determinism" is "a form of analysis and prediction in which climate is first extracted from the matrix of interdependencies that shape human life within the physical world". Within this discourse it is often the biophysical sphere that is employed to explain the course of human behavior; consequently, this dominating perspective threatens to skew our predictions and understandings of future societies, cultures, climates and destinies. Climate change will certainly constrain human agency, but it also creates the potential for geography to play to its intra and inter disciplinary strengths and begin discussing and addressing human-environmental dilemmas in practical and realistic ways; and secondly, seize the climate change crisis as an opportunity to study where, why and for whom global environmental change matters. Firstly, this paper considers a theoretical

    Depression is a major concern for public health. Both adverse working conditions and low socio-economic position are suspected to increase risk of depression. In a representative sample of the Danish workforce we investigated (i) whether adverse psychosocial working conditions, defined by the effort-reward imbalance (ERI) model, predicted onset of severe depressive symptoms after 5-year follow-up and (ii) whether the effect of ERI was differential across occupational grades. A cohort of 2701 Danish employees filled in a questionnaire on work and health in 2000 and 2005. ERI was measured with four effort and seven reward items. Depressive symptoms were assessed with the five-item Mental Health Inventory. Participants scoring ≤ 52 points were defined as cases. We used logistic regression to investigate the association of ERI and occupational grade in 2000 with onset of severe depressive symptoms in 2005. Analyses were adjusted for socio-demographics, health behaviours, survey method, self-rated health, sleep disturbances and non-severe depressive symptoms at baseline. High ERI predicted onset of severe depressive symptoms at follow-up, after adjustment for co-variates and occupational grade (OR = 2.19, 95% CI = 1.12-4.25). Participants with high ERI and low occupational grade showed a considerably higher OR (2.43, 95% CI = 1.07-5.53) compared to participants with low/medium ERI and low grade (OR = 1.45, 95% CI = 0.72-2.92), high ERI and high grade (OR = 1.26, 95% CI = 0.59-2.70) and low/medium ERI and high grade (reference group). Adverse psychosocial working conditions predicted onset of severe depressive symptoms. The effect was stronger among employees of lower occupational grades compared to those of higher grades.

    The objective of the study was to evaluate the occurrence of Burnout Syndrome in 100 teachers of six public high schools and its correlation with working conditions in a southeast city of Brazil. Characterization of the sample occurred after application of a socio-demographic questionnaire. Evaluation of the working conditions was done by means of an Ergonomic Working Analysis. The presence of Burnout Syndrome was evaluated by means of the Maslach Burnout Inventory. The sample presented the predominance of women, with an average age of 40.4 and the majority married with children. Roughly 50% had less than 10 years of service, and more than half of the teachers taught more than 18 classes per week. Hoarseness after work was principally reported among women, which required many days off for health treatment. Environmental conditions reflect inadequacy in relation to noise, light, humidity and temperature. Presence of pain in the upper limbs was especially high among women. Risk of musculoskeletal disorders in the upper limbs predominated as moderately important to significant. We also identified an average distance walked by teachers of 1.5 Km and an average of 4.2 Kg of school supplies carried between classes. The Burnout Syndrome presented a high score for depersonalization principally among men, but it has association with both sexes. Emotional exhaustion correlates with noise, depersonalization, and personal fulfillment, in addition to the high number of weekly lessons. It can be concluded that Burnout syndrome is present among teachers, principally in terms of depersonalization, deserving the attention of government officials and the schools, as well as the teachers themselves.

    Full Text Available This article explores the degree to which student collaborations on research and writing assignments can effectively realize learning outcomes. The assignment, in this case, encouraged students to contribute discrete parts of a research project in order to develop their complementary abilities: researching, consulting, drafting, and revising. The outcomes for students included appreciation for their individual expertise, and experience combining discrete contributions into a result that surpasses the sum of its parts. In the course, we gave students preliminary guidance for establishing team objectives and roles for the duration of this assignment and asked them to evaluate their learning experience at the end. In this paper, we analyze the students’ quantitative and qualitative feedback, and suggest ways to structure and supervise collaborative assignments so that students develop their expertise and complementary skills. We suggest that collaborative work such as this is essential for advanced undergraduates in the humanities, where collaborations are less common than in other disciplines. Moreover, we conclude that future humanities instructors should be open to the benefits of collaborative research and writing. This article will be of interest to instructors who wish to develop collaborative assignments that improve students’ disciplinary expertise, engagement with course materials, and outreach to audiences beyond the academy. Cet article explore la mesure dans laquelle le travail en collaboration des étudiants en matière de recherche et de rédaction de devoirs peut aboutir à des résultats d’apprentissage efficaces.

    Full Text Available Abstract Background The role of social and family environments in the development of mental health problems among children and youth has been widely investigated. However, the degree to which parental working conditions may impact on developmental psychopathology has not been thoroughly studied. Methods We conducted a case-control study of several mental health outcomes of 19,833 children of sawmill workers and their association with parental work stress, parental socio-demographic characteristics, and paternal mental health. Results Multivariate analysis conducted with four distinct age groups (children, adolescents, young adults, and adults revealed that anxiety based and depressive disorders were associated with paternal work stress in all age groups and that work stress was more strongly associated with alcohol and drug related disorders in adulthood than it was in adolescence and young adulthood. Conclusion This study provides support to the tenet that being exposed to paternal work stress during childhood can have long lasting effects on the mental health of individuals.

    Although obesity is well established in hamsters, studies using diets with high levels of simple carbohydrate associated with lipids are necessary to assess the impact of this type of food in the body. In this study a high sugar and butter diet (HSB) and high temperature were employed towards this end. Obesity was successfully induced at a temperature of 30.3°C to 30.9°C after 38 days feeding the animals an HSB diet. It was shown that although diet is important for the induction of obesity, temperature is also essential because at a temperature slightly below the one required, obesity was not induced, even when the animals were fed for a longer period (150 days).The obese clinical condition was accompanied by biochemical and hematological changes, as increased cholesterol and triglyceride levels and increased leukocyte numbers, similar to alterations observed in obese humans. Furthermore, it was demonstrated that increasing the intake of simple carbohydrates associated with lipids provided evidence of inflammation in obese animals.

    Two experiments were conducted with the aim of designing a videogame for the study of human conditioned avoidance. Participants had to destroy enemy spaceships with the goal of increasing the score in a counter. Coloured signals might announce the launching of a bomb that could hit participant's spaceship producing a 30 points decrease in participant's score. Three groups of participants were trained in discriminating between a warning signal (W) and a safety signal (S) in Experiment 1. Instrumental group could avoid the loss of points by hiding the spaceship before the offset of W. Participants in the Yoked group received the same treatment received by their instrumental partners, regardless of their behaviour. In the Pavlovian group, W was always followed by the loss of points, regardless of participant's behaviour. Discrimination between W and S was better in the Instrumental groups than in the Yoked and Pavlovian control groups. Experiment 2 found extinction of avoidance when the warning signal was not followed by the bomb. Temporal discrimination was found within the participants that received the instrumental contingency in both experiments, with higher avoidance response towards the end of the warning signal. Temporal discrimination disappeared after extinction in Experiment 2.

    This study examined whether asthma alone or together with chronic comorbidity is associated with an increased risk of long-term work disability. We examined data from 2332 asthmatic and 66 354 nonasthmatic public sector employees in Finland who responded to a survey between 1997 and 2004. Respondents were coded as persistent asthmatics based on the special reimbursement for continuous asthma medication by the Social Insurance Institution. Data on long-term work disability (sickness absences or disability pensions > 90 days) were obtained from national registers. The risk of work disability was examined by Cox proportional hazard models adjusted for age, gender, socioeconomic status, type of employment contract, and type of employer. Asthma increased the risk of all-cause long-term work disability with hazard ratio (HR) 1.8 (95% CI 1.62-2.09) compared with controls (no asthma). Asthma and one other chronic comorbidity increased the risk of long-term all-cause work disability with HR 2.2 (95% CI 1.78-2.83). Asthma together with two or more other chronic conditions increased the risk with HR 4.5 (95% CI 2.98-6.78). Asthma and depression increased the risk with HR 3.6, and the risk was especially high for permanent work disability (HR 6.8). Among those with asthma, there were more women, obese individuals (BMI ≥ 30), ex-smokers, and lower-grade nonmanual workers. Asthma is associated with an increased risk of long-term all-cause work disability. The risk increases further with chronic comorbidities and is especially high in patients with asthma and depression. © 2011 John Wiley & Sons A/S.

    Workers in Primary Health Care are often exposed to stressful conditions at work. This study investigated the association between adverse psychosocial work conditions and poor quality of life among Primary Health Care workers. This cross-sectional study included all 797 Primary Health Care workers of a medium-sized city, Brazil: doctors, nurses, nursing technicians and nursing assistants, dentists, oral health technicians, and auxiliary oral hygienists, and community health workers. Data were collected by interviews. Quality of life was assessed using the WHOQOL-BREF; general quality of life, as well as the physical, psychological, social and environmental domains were considered, with scores from 0 to 100. Higher scores indicate a better quality of life. Poor quality of life was defined by the lowest quartiles of the WHOQOL score distributions for each of the domains. Adverse psychosocial work conditions were investigated by the Effort-Reward Imbalance model. Associations were verified using multiple logistic regression. Poor quality of life was observed in 117 (15.4%) workers. Workers with imbalanced effort-reward (high effort/low reward) had an increased probability of general poor quality of life (OR = 1.91; 1.07–3.42), and in the physical (OR = 1.62; 1.02–2.66), and environmental (OR = 2.39; 1.37–4.16) domains; those with low effort/low reward demonstrated a greater probability of poor quality of life in the social domain (OR = 1.82; 1.00–3.30). Workers with overcommitment at work had an increased likelihood of poor quality of life in the physical (OR = 1.55, 1.06–2.26) and environmental (OR = 1.69; 1.08–2.65) domains. These associations were independent of individual characteristics, job characteristics, lifestyle, perception of general health, or psychological and biological functions. There is an association between adverse psychosocial work conditions and poor quality of life among Primary Health Care workers.

    The global optimal working conditions and optimal couple design for thermoelectric (TE) generators with realistic thermal coupling between the heat reservoirs and the TE couple were studied in the current work. The heat fluxes enforced by the heat reservoirs at the hot and the cold junctions of the TE couple were used in combination with parameter normalization to obtain a single cubic algebraic equation relating the temperature differences between the TE couple junctions and between the heat reservoirs, through the electric load resistance ratio, the reservoir thermal conductance ratio, the reservoir thermal conductance to the TE couple thermal conductance ratio, the Thomson to Seebeck coefficient ratio, and the figure of merit (Z) of the material based on the linear TE transport equations and their solutions. A broad reservoir thermal conductance ranging between 0.01 W/K and 100 W/K and TE element length ranging from 10-7 m to 10-3 m were explored to find the global optimal systems. The global optimal parameters related to the working conditions, i.e., reservoir thermal conductance ratio and electric load resistance ratio, and the optimal design parameter related to the TE couple were determined for a given TE material. These results demonstrated that the internal and external electric resistance, the thermal resistance between the reservoirs, the thermal resistance between the reservoir and the TE couple, and the optimal thermoelement length have to be well coordinated to obtain optimal power production.

    Full Text Available Women constitute nearly 41%of academic staff in our country. Among all academic staff, the ratio of female academicians is increasing as it is approached to rural areas from suburbs. This study aims to reveal the perceptions of undergraduate education students about female academicians’ working life conditions. Considering available time and facilities, the universe of research was limited within a university; as it was primarily intended to reveal students’ individual perceptions on the conditions of women academics, the students’ being at the undergraduate level was at the fore front of study rather than the academic departments of the university. The survey data form were applied to 157 female and 104 male undergraduate students (N = 261 studying at faculties and schools of the university where the survey was applied excluding freshmen classes.. Descriptive tests were used to evaluate the data. The findings were evaluated by x ² test, which were formerly tested according to the desires of students on what to get on their education and whether they were willing to be academicians. 54%of female students involved in the research stated that they were “partially” satisfied with the female academics. While 74,3%of the students agreed on the question “Should women work as academicians?”, only 2.2%percent stated that women should not work as academicians. 47,8%consider that there is a partial discrimination between the male and female members of academic life. 47,1%mentioned that working as an academician was a barrier to being a good mother or a good wife and 69,7%stated that working as a female academician was a tough work. 23,7%of the students think that being an academician is mostly beneficial in terms of personal development for a woman. 79,6%stated that the biggest challenge for female academics is to sustain the academic studies as well as being a mother and a wife. The best advantage of being female academician was revealed

    To create healthy and safe working conditions are constantly in the focus of attention at all governmental levels. To reduce deaths and traumatism from occupational accidents and diseases, by providing safe working conditions is one of the priorities of the demographic policy pursued by the Government of the Russian Federation. In the able-bodied population, the current mortality from natural causes (accidents, poisonings, and traumas, including occupation-related ones) exceeds that by 2.5 and 1.5 times in developed and developing countries, respectively. The worse conditions remain to be those in coal-mining and shipbuilding industries, ferrous and non-ferrous metallurgy, agriculture, tractor-building and agricultural engineering, building materials industry, road-building machinery, logging industry, power machine building, and civil engineering. On-going checks reveal low sanitary culture and industrial discipline, no package of sanitary-and-prophylactic measures, as well as poor knowledge about sanitary legislation requirements in the heads of small-scale business and private undertakings. In 2006, the Russian Federation notified 357 cases of occupational diseases among medical workers, of which there were 196 cases of pulmonary tuberculosis and 39 cases of viral hepatitis. Despite the fact that the cases of occupational diseases are annually on the decrease, these are being underdetected.

    Full Text Available An indispensable component of ensuring safe control of railway and sea transport in conditions of hot climate is maintenance of comfortable temperature of air in control cabins and living spaces. Now the interest is restored to use the Air Refrigerating Plants (ARP as they have a wide potential of low-temperature cooling without use of ozone-destructive cooling agents prohibited by decision of the Montreal meeting. At the same time, air conditioning installations on the basis of turbo-expanders have low refrigerating factor, they are very expensive in manufacturing and require a high level of maintenance service.Alternative trend of perfection of air refrigeration units is connected with a new principle of organization of working process, based on the use as expander and compressor of aggregates of cascade exchanger of pressure (CPE. Besides of unsurpassed efficiency of exchange processes, CPE is characterized by simplicity of design and high reliability, including, due to low frequency of rotation (2000-3000 min-1 with practically absence of consumption of mechanical energy on the drive of the rotor. The attractive aspect of application of equipment of conditioning with CPE is the opportunity of organization of working process only due to thermal energy including the utilization in the heat-power installation of transport vehicle.

    Highlights: • EWF and friction behavior of alloys in different conditions are investigated. • Damaged fresh active broken-bond on surface leads higher EWF and larger adhesion. • Inactive broken-bond covered with passive film leads higher EWF and lower adhesion. • Freshly polished surfaces and etched ones are consistent with above behaviors. - Abstract: Electron work function (EWF), adhesion and friction coefficient of three passive alloys were investigated. During dry sliding tests, surfaces having higher work functions showed larger coefficients of friction. While under oil-lubricated sliding condition, the trend was reversed. It appears that when the surface passive film was damaged, the surface broken atomic bonds became active, leading to larger friction. However, under the oil-lubricated sliding condition, the passive film was retained, resulting in a different trend. Surface adhesive forces of freshly polished surfaces and etched ones were measured using an atomic force microscope. Results of the adhesion measurement are consistent with the behaviors of the alloys observed during the friction tests.

    Full Text Available Abstract Background Germany currently experiences a situation of major physician attrition. The incompatibility between work and family has been discussed as one of the major reasons for the increasing departure of German physicians for non-clinical occupations or abroad. This study investigates predictors for one particular direction of Work-Family Conflict – namely work interfering with family conflict (WIF – which are located within the psychosocial work environment or work organisation of hospital physicians. Furthermore, effects of WIF on the individual physicians' physical and mental health were examined. Analyses were performed with an emphasis on gender differences. Comparisons with the general German population were made. Methods Data were collected by questionnaires as part of a study on Psychosocial work hazards and strains of German hospital physicians during April–July 2005. Two hundred and ninety-six hospital physicians (response rate 38.9% participated in the survey. The Copenhagen Psychosocial Questionnaire (COPSOQ, work interfering with family conflict scale (WIF, and hospital-specific single items on work organisation were used to assess WIF, its predictors, and consequences. Results German hospital physicians reported elevated levels of WIF (mean = 74 compared to the general German population (mean = 45, p p Conclusion In our study, work interfering with family conflict (WIF as part of Work-Family Conflict (WFC was highly prevalent among German hospital physicians. Factors of work organisation as well as factors of interpersonal relations at work were identified as significant predictors for WIF. Some of these predictors are accessible to alteration by improving work organisation in hospitals.

    Accidental exposure to cold water environment is one of the most challenging situations in which hypothermia occurs. In the present work, we aim to characterise the energy balance of a human body subjected to such extreme environmental conditions. This study is carried out using a recently developed computational model and by setting boundary conditions needed to simulate the effect of cold surrounding environment. A major finding is the capacity of the body core regions to maintain their temperature high for a substantial amount of time, even under the most extreme environmental conditions. We also considered two disease states that highlight the spectrum of possible pathologies implicated in thermal regulation of the human body. These states are (i) cardiomyopathy, which affects the operating capacity of the heart, and (ii) malnutrition, which directly impairs the body's ability to regulate heat exchange with the environment. We have found that cardiomyopathy has little influence on the thermal balance of the human body, whereas malnutrition has a profound negative effect on the thermal balance and leads to dramatic reduction in core temperature.

    The strategy for the improvement of occupational safety and health is presented. The role of the state and the workers in shaping working conditions has changed over the years, and this process is traced through ILO and EC documents. There must be a coherent up-to-date national policy in this field. Safety and the protection of the workers' health is perceived by the Community legislation not only in the terms of the worker's individual interest, but also from a social viewpoint, consisted in striving for general improvement of the work environment. The Community regulations aspire to satisfy the public interest, and directives set the maximum level of protection but also serve as minimum standards not infringing the more favourable national regulations. They define requirements that should already be met at the planning and designing stages.

    2014-01-01

    In industrially developing countries (IDC), small and medium enterprises (SMEs) account for the highest proprotion of employment. Unfortunately, the working conditions in SMEs are often very poor and expose employees to a potentially wide range of health and safety risks. This paper presents a comprehensive review of 161 articles related to ergonomics application in SMEs, using Indonesia as a case study. The aim of this paper is to investigate the extent of ergonomics application and identify areas that can be improved to promote effective ergonomics for SMEs in IDC. The most urgent issue found is the need for adopting participatory approach in contrast to the commonly implemented top-down approach. Some good practices in ergonomics application were also revealed from the review, e.g. a multidisciplinary approach, unsophisticated and low-cost solutions, and recognising the importance of productivity. The review also found that more work is still required to achieve appropriate cross-cultural adaptation of ergonomics application.

    The contribution of occupation and work organisation conditions to the development of chronic psychological distress in the Canadian workforce was examined. Longitudinal data came from the first five cycles (Cycle 1=1994-1995, Cycle 5=2002-2003) of Statistics Canada's National Population Health Survey. A sample of 5,500 workers nested in 1,300 neighbourhoods and aged 15 to 55 years. Data had a hierarchical structure and were analysed using multilevel logistic regression models. The results showed 46.4% of workers reported one episode of psychological distress, 23.5% more than one, and 10.6% three or more. Psychological distress decreased over time and varied significantly between individuals and neighbourhoods. Occupation was not significant, but psychological demands, job insecurity, and social support in the workplace were important determinants. The results showed strong contributions of individual and outside work factors (family, social support, neighbourhood). Research in occupational mental health must expand theoretical and empirical frameworks in order to capture actual workplace dynamics and the effects on workers' mental health. Interventions designed to reduce mental health problems should carefully evaluate not only the work environment itself, but also non-work factors and other individual characteristics.

    Full Text Available Abstract Background Working conditions of nursery school teachers have not been scrutinized thoroughly in scientific research. Only a few studies have so far examined work-load and strain in this profession. Preferably, subjective perceptions should be corroborated by data that can be quantified more objectively and accurately. The aim of the present observational field study was to evaluate pedagogical staffs' workflow. Methods In 2009 eleven educators in a day care centre were observed throughout three complete workdays. A total of 250 working hours were recorded. Results An educators' workday lasted on average 07:46:59 h (SD = 01:01:10 h. Within this time span, an average of 02:20:46 h (30.14%, SD = 00:28:07 h were spent on caring, 01:44:18 h on playing (22.33%, SD = 00:54:12 h, 00:49:37 h on educational work (10.62%, SD = 00:40:09, and only 00:05:38 h on individual child contact (1.21%, SD = 00:04:58 h. Conclusion For the first time, educators' workflow in day care centres was studied in real time. Some of the educators' self-reported problems were corroborated. The results of this study form a basis upon which further investigations can be built and measures can be developed for an overall improvement of child care.

  4. The Art of the Possible: Making films on sex work migration and human trafficking

    Full Text Available Fiction films and documentaries increasingly bring the themes of sex work migration and human trafficking to the big screen. The films often focus on women who have experienced a range of abusive conditions within the sex industry, experiences which in the films typically are all labelled ‘trafficking’ and narrated through the capture of innocents and their rescue. Images of ‘sex slaves’ have thus entered the film scene as iconic figures of pain and suffering, and ‘traffickers’ have emerged as icons of human evil. Building upon the substantial scholarly critique of such films and representations, this article discusses the possibilities of making films about migrant sex workers (some of whom may be trafficked that do not fall into misleading and sensationalised representations. I draw upon two films about women migrant sex workers that I have worked on as an anthropologist and filmmaker—Trafficking (2010 and Becky’s Journey (2014. The point of departure is that there are a range of other aspects that can influence the filmmaking process rather than merely a one-dimensional perspective on sex work and trafficking. While analysing the making of these two films I look at the reasons—both theoretical and practical—for certain production decisions and the ways in which films in the context of multiple challenges are often the result of the art of the possible.

    NASA and its partners are committed to introducing appropriate new technology to enable learning and living safely beyond the Earth for extended periods of time in a sustainable and possibly indefinite manner. In the responsible acquisition of that goal, life sciences is tasked to tune and advance current medical technology to prepare for human health and wellness in the space environment. The space environment affects the condition and function of biological systems from organ level function to shape of individual organelles. The objective of this paper is to study the effect of microgravity on kinetics of drug metabolism. This fundamental characterization is meaningful to (1) scientific understanding of the response of biology to microgravity and (2) clinical dosing requirements and pharmacological thresholds during long term manned space exploration. Metabolism kinetics of the anti-nausea drug promethazine (PMZ) were determined by an in vitro ground model of 3-dimensional aggregates of human hepatocytes conditioned to weightlessness using a rotating wall bioreactor. The authors observed up-regulated PMZ conversion in model microgravity conditions and attribute this to effect to model microgravity conditioning acting on metabolic mechanisms of the cells. Further work is necessary to determine which particular cellular mechanisms are governing the experimental observations, but the authors conclude kinetics of drug metabolism are responsive to gravitational fields and further study of this sensitivity would improve dosing of pharmaceuticals to persons exposed to a microgravity environment.

  7. Role of human premotor dorsal region in learning a conditional visuomotor task.

    Parikh, Pranav J; Santello, Marco

    2017-01-01

    Conditional learning is an important component of our everyday activities (e.g., handling a phone or sorting work files) and requires identification of the arbitrary stimulus, accurate selection of the motor response, monitoring of the response, and storing in memory of the stimulus-response association for future recall. Learning this type of conditional visuomotor task appears to engage the premotor dorsal region (PMd). However, the extent to which PMd might be involved in specific or all processes of conditional learning is not well understood. Using transcranial magnetic stimulation (TMS), we demonstrate the role of human PMd in specific stages of learning of a novel conditional visuomotor task that required subjects to identify object center of mass using a color cue and to apply appropriate torque on the object at lift onset to minimize tilt. TMS over PMd, but not vertex, increased error in torque exerted on the object during the learning trials. Analyses of digit position and forces further revealed that the slowing in conditional visuomotor learning resulted from impaired monitoring of the object orientation during lift, rather than stimulus identification, thus compromising the ability to accurately reduce performance error across trials. Importantly, TMS over PMd did not alter production of torque based on the recall of learned color-torque associations. We conclude that the role of PMd for conditional learning is highly sensitive to the stage of learning visuomotor associations.

    Companies’ internationalization appears to be fundamental in the current globalized and competitive environment and seems important not only for organizational success, but also for societal development and sustainability. On one hand, global business increases the demand for managers for international assignment. On the other hand, emergent fears, such as terrorism, seem to be developing around the world, enhancing the risk of expatriates’ potential health problems. The purpose of this paper is to examine the relationships between the emergent concept of fear of expatriation with further workplace fears (economic crisis and dangerous working conditions) and with mental health problems. The study uses a quantitative design. Self-reported data were collected from 265 Italian expatriate workers assigned to both Italian and worldwide projects. Structural equation model analyses showed that fear of expatriation mediates the relationship of mental health with fear of economic crisis and with perceived dangerous working conditions. As expected, in addition to fear, worries of expatriation are also related to further fears. Although, the study is based on self-reports and the cross-sectional study design limits the possibility of making causal inferences, the new constructs introduced add to previous research.

    Full Text Available Companies’ internationalization appears to be fundamental in the current globalized and competitive environment and seems important not only for organizational success, but also for societal development and sustainability. On one hand, global business increases the demand for managers for international assignment. On the other hand, emergent fears, such as terrorism, seem to be developing around the world, enhancing the risk of expatriates’ potential health problems. The purpose of this paper is to examine the relationships between the emergent concept of fear of expatriation with further workplace fears (economic crisis and dangerous working conditions and with mental health problems. The study uses a quantitative design. Self-reported data were collected from 265 Italian expatriate workers assigned to both Italian and worldwide projects. Structural equation model analyses showed that fear of expatriation mediates the relationship of mental health with fear of economic crisis and with perceived dangerous working conditions. As expected, in addition to fear, worries of expatriation are also related to further fears. Although the study is based on self-reports and the cross-sectional study design limits the possibility of making causal inferences, the new constructs introduced add to previous research.

    The Brillouin fiber amplifier (BFA) has been used in Brillouin optical time and frequency domain analyzer based sensors. For BFA based distributed sensor the optimized working condition is to have the highest Brillouin gain, i.e., highest SNR, which avoids high pump depletion induced gain saturation. We have found that the optimum working condition for distributed sensor system is associated with the stimulated Brillouin scattering (SBS) threshold for BFA, which can be experimentally determined with Stokes power inflexion and/or Stokes spectrum linewidth minimum methods. This threshold depends on both pump and probe power instead of just the pump power as in Brillouin fiber generator (BFG), as well as on sensing length as confirmed by our experimental results and theoretical simulation. This was achieved by introducing the concept of absorption coefficient of the sensing medium defined as the ratio of the total output power to the total input power. We find that the medium absorption is minimized when input Stokes power is an order of magnitude lower than BFA threshold. This minimum is a signature of the balance between maximum Stokes gain and pump depletion which is also the reason why Stokes spectrum linewidth goes through a minimum.

    Full Text Available Objective: to analyze the relationship between working conditions and health status using the data provided by The First Colombian National Survey on Health and Working Conditions (I-ENCST. Methods: a cross-sectional study was conducted on 931 workers from 737 work centers. The outcome variable was self-perceived health status (good/poor. Exposure variables were working conditions, i.e. hygiene, safety, ergonomic, and psychosocial risk factors. Additional variables were: sex, age, social class, education level, geographic region, and economic activity. We estimated the relationship between working conditions and health status using crude odds ratios (OR that were adjusted through logistic regression with their confidence intervals at 95% (CI95%. Results: workers exposed to the following factors had a higher probability of having a poor health status: insufficient working space (aOR 3.9; 95%CI 1.9-8.3, “the position held does not make it possible to develop skills” (aOR 6.2; 95%CI 2.6-14.7, the work center is very unsafe or not very safe (aOR 7.5; 95%CI 3.0-18.6, and the tools or workstation are inadequate (aOR 5.6; 95%CI 2.3-14.0. Discussion: of the analyzed population, individuals exposed to precarious working conditions had a higher risk of having a poor health status.

    Flexible working conditions are increasingly popular in developed countries but the effects on employee health and wellbeing are largely unknown. To evaluate the effects (benefits and harms) of flexible working interventions on the physical, mental and general health and wellbeing of employees and their families. Our searches (July 2009) covered 12 databases including the Cochrane Public Health Group Specialised Register, CENTRAL; MEDLINE; EMBASE; CINAHL; PsycINFO; Social Science Citation Index; ASSIA; IBSS; Sociological Abstracts; and ABI/Inform. We also searched relevant websites, handsearched key journals, searched bibliographies and contacted study authors and key experts. Randomised controlled trials (RCT), interrupted time series and controlled before and after studies (CBA), which examined the effects of flexible working interventions on employee health and wellbeing. We excluded studies assessing outcomes for less than six months and extracted outcomes relating to physical, mental and general health/ill health measured using a validated instrument. We also extracted secondary outcomes (including sickness absence, health service usage, behavioural changes, accidents, work-life balance, quality of life, health and wellbeing of children, family members and co-workers) if reported alongside at least one primary outcome. Two experienced review authors conducted data extraction and quality appraisal. We undertook a narrative synthesis as there was substantial heterogeneity between studies. Ten studies fulfilled the inclusion criteria. Six CBA studies reported on interventions relating to temporal flexibility: self-scheduling of shift work (n = 4), flexitime (n = 1) and overtime (n = 1). The remaining four CBA studies evaluated a form of contractual flexibility: partial/gradual retirement (n = 2), involuntary part-time work (n = 1) and fixed-term contract (n = 1). The studies retrieved had a number of methodological limitations including short follow-up periods

    2017-05-01

    Full Text Available It is well known that the textile and clothing industry plays an extremely important role in the global context, being one of the most powerful industries, which is capable of generating a turnover of billions of EUR. A fundamental part of the manufacturing process is represented by the employees that have an essential place in each step of the value chain, from fibre to fabric to ready-to-use product. The majority of the companies in this domain use the “lohn” system, which means that, first of all, that they redirect their attention to the countries which offer a cheap manpower. As a consequence, countries such as Romania lose their own identity regarding their own brands, becoming just a so considered minor player in the textile and clothing industry, but having the significant role of producing for the big companies of the world. The aim of this paper is to point out the great importance of the people who work in this industry, from the unqualified personnel to the qualified one, because each of one has a specific role in the manufacturing process, and also to emphasize that companies should not minimize this fact; on the contrary, besides worrying only about the profit, attention should be focused primarily on employees, in order to create optimal working conditions, to respect the fundamental human rights and to provide wages proportionally with the work-hours.

  16. Through doctors' eyes: A qualitative study of hospital doctor perspectives on their working conditions.

    2013-03-11

    BACKGROUND: Hospital doctors face significant challenges in the current health care environment, working with staff shortages and cutbacks to health care expenditure, alongside increased demand for health care and increased public expectations. OBJECTIVE: This article analyses challenges faced by junior hospital doctors, providing insight into the experiences of these frontline staff in delivering health services in recessionary times. DESIGN: A qualitative methodology was chosen. METHODS: Semi-structured in-depth interviews were conducted with 20 doctors from urban Irish hospitals. Interviews were recorded via note taking. Full transcripts were analysed thematically using NVivo software. RESULTS: Dominant themes included the following: (1) unrealistic workloads: characterised by staff shortages, extended working hours, irregular and frequently interrupted breaks; (2) fatigue and its impact: the quality of care provided to patients while doctors were sleep-deprived was questioned; however, little reflection was given to any impact this may have had on junior doctors own health; (3) undervalued and disillusioned: insufficient training, intensive workloads and a perceived lack of power to influence change resulted in a sense of detachment among junior doctors. They appeared immune to their surroundings. CONCLUSION: Respondents ascribed little importance to the impact of current working conditions on their own health. They felt their roles were underappreciated and undervalued by policy makers and hospital management. Respondents were concerned with the lack of time and opportunity for training. This study highlighted several \\'red flags\\

    The scope of this paper is to analyze and interpret the problems and prospects of trade union activity, in order to achieve changes in the workplace and promote health in schools by means of the experience of the Training Program in Health, Gender and Work in Public Schools. In order to conduct this research we staged interviews with union leaders and education professionals. In our analysis we concentrated on the report of a specific case, namely the State Union of Education Professionals in Rio de Janeiro (SEPE-RJ). We perceived that, after the training program, the campaign began to focus not only on the defense of certain rights that are traditionally present on the union agenda. The concept of health broadens the union concept of working conditions; it also allows workers in schools to be the protagonists of movements for change. We note, moreover, the sense of renewal that the theme "work"--in its relation to health--has given to trade union militancy.

    Terrestrial Laser Scanning is a popular and widely used technique to scan existing objects, document historical sites and items, and remodel them if and when needed. Their ability to collect thousands of point data per second makes them an invaluable tool in many areas from engineering to historical reconstruction. There are many scanners in the market with different technical specifications. One main technical specification of laser scanners is range and illumination. In this study, it is tested to be determined the optimal working times of a laser scanner and the scanners consistency with its specifications sheet. In order to conduct this work, series of GNSS measurements in Istanbul Technical University have been carried out, connected to the national reference network, to determine precise positions of target points and the scanner, which makes possible to define a precise distance between the scanner and targets. Those ground surveys has been used for calibration and registration purposes. Two different scan campaigns conducted at 12 am and 11 pm to compare working efficiency of laser scanner in different illumination conditions and targets are measured with a handheld spectro-radiometer in order to determine their reflective characteristics. The obtained results are compared and their accuracies have been analysed.

    Full Text Available In this article, we analyze the relation among educational reforms and teachers’ work, and emotions. This study was conducted with a public school English teacher, in Minas Gerais. The aim was to verify the role that contextual factors play in the production of emotions, and detect the emotions that influence her practice with students, colleagues, and school managers. The theoretical framework was based on studies about educational reforms and teachers’ work (AUGUSTO, 2005; HYPOLITO; VIEIRA; PIZZI, 2009; DUARTE; AUGUSTO, [s.d.], the relationship between emotions and the process of teaching and learning languages (HARGREAVES, 2000; ZEMBYLAS, 2002, 2003; ARAGÃO, 2008; DAY; QING, 2009; SHUTZ; ZEMBYLAS, 2009; COWIE, 2011; RIBEIRO, 2012. We used a semistructured questionnaire and a narrative interview as data collection instruments. The analysis has pointed out poor work condition, crowded classrooms, poor physical and technological structures, strict school curriculum, students’ indiscipline, and the institution pessimistic atmosphere as frustrating, stressful, and de-motivating factors. These results indicate the need to create alternative ways of school workplaces organization, and to modify the way people interact in schools. They also suggest the need of educators to participate in the design and implementation of educational reforms.

  20. Robots, Industry 4.0 and Humans, or Why Assembly Work Is More than Routine Work

    Directory of Open Access Journals (Sweden)

    Sabine Pfeiffer

    2016-05-01

    Full Text Available This article condenses the key findings of qualitative studies on assembly work. Grounded conceptually in considerations of the role of experiential knowledge and living labor capacity with regard to informal expertise and tacit knowledge, the empirical results challenge the dominant view of assembly work as routine tasks that could easily be replaced by robotics. The empirical basis comprised of 62 qualitative interviews in five assembly plants provides answers to two questions: Are there non-routine aspects to be found in assembly work today? What exactly is the nature of experience in assembly work? The detailed research results are presented in three steps: the first focuses on the role of the non-routine in core assembly tasks; the second discusses the important and increasing role played by interactive capabilities in assembly work to ensure high performance, quality, and a smooth material flow; and the third highlights the usually neglected role of assembly workers in processes of innovation and organizational learning. The concluding chapter discusses the findings from the perspective of new technological options in robotics, possible worker resistance and effects on employment.

  1. Tensions between work and home: job quality and working conditions in the institutional contexts of Germany and Spain.

    Good jobs can generate capabilities that allow employees to avoid tensions between work and family/home. Following the conceptual framework of Amartya Sen, we examine how job-related demands and resources are related to the level of interference, as well as satisfaction with managing work and home in Spanish and German employees, using three different large-scale European surveys: European Quality of Life Survey and two waves of the European Social Survey. We find that long working hours systematically increase tensions between work and home, as do time pressure, job-related stress, and working hard. Job control or autonomy at work, which is hypothesized to expand individuals' capabilities and agency, tends to increase work–home interference rather than alleviate it. Family responsibilities and household demands do not seem relevant to the tensions employees experience at the work–home interface. This also holds true for women, which is a surprising result in view of the “double burden” hypothesis. Employed mothers in Germany and Spain are a select group of women, as combining employment with raising children in conservative–corporatist and conservative–familialist states may be particularly problematic. Thus while the institutional contexts of Germany and Spain curtail women's ability to reconcile employment and parenthood, the mothers (and fathers) who are employed do not experience significantly higher levels of work–family/home tensions than nonparents.

    The strategic human capital literature indicates the importance of human capital to work unit performance. However, we argue that human capital only aids performance when it is translated into actions beneficial to the unit. We examine a set of common human capital leveraging characteristics (including the use of extended shifts, night shifts, shift flexibility, norms for work as a priority over sleep, and norms for constant connectivity) as factors that enhance the effect of human capital on human capital utilization. We also draw from the 2-process model of sleep regulation to examine how these characteristics undermine employee sleep, and thus weaken the link between human capital and work unit performance efficiency. Overall, we propose that human capital leveraging strategies initially enhance the effect of human capital on work unit performance, but over time weaken the effect of human capital on work unit performance efficiency. Thus, strategies intended to enhance the beneficial effect of human capital on work unit performance can end up doing the opposite.

    The system of human activity, which is established by genetics and regulated by outer and inner factors, is associated with many characteristics which maintain the body in the best condition and ensure appropriate life quality. To evaluate of life quality among male shift-workers. Research based on a self-devised questionnaire, conducted among 700 shift-workers, followed by statistical analysis of the results. Nearly a half of respondents (43.00%) reported that shift-work influences the quality of their family life. Remarkably, such an opinion was often stated by people with children (46.01%) pwork negatively influence their sexual life (31.14%). It was shown that shift-work negatively influences the respondents' life quality in the form of deterioration of the quality of family life; the respondents, regardless of marital status, age and having children, most often complained about the lack of contact with the family and irregular eating with them; negative influence on sexual life, which was the case in one-third of respondents. In order to encourage healthy behaviour and increase the quality of life of people performing shift-work, training and programmes should be introduced. These would help shift- workers to adjust their work time to their family and social life.

    Full Text Available The objective of this work is the assessment of human thermal bioclimatic conditions in the Athens University Campus (AUC, including the Faculties and their respective Departments of the largest state institution of higher learning in Greece, and among the largest universities in Europe. The analysis of bioclimate was carried out, using the physiologically equivalent temperature (PET, which is based on the energy balance model of the human body. The meteorological data required for the calculation of PET concern hourly values of air temperature, relative humidity, wind speed and total solar radiation, for the time period 1999–2007. The recorded data sets were obtained from the meteorological station of the Laboratory of Climatology and Atmospheric Environment of the University of Athens. The results revealed the hours of the day in which thermal comfort or stress prevails, as well as the trends and variability of PET, for the studied period. Finally, the intense heat waves occurred during summer 2007 along with extreme cold conditions during December 2003-February 2004 were analyzed in terms of PET classes and compared to the respective average bioclimatic conditions of the study period.

  15. Inferior frontal gyrus preserves working memory and emotional learning under conditions of impaired noradrenergic signaling

    Directory of Open Access Journals (Sweden)

    Benjamin eBecker

    2013-12-01

    Full Text Available Compensation has been widely applied to explain neuroimaging findings in neuropsychiatric patients. Functional compensation is often invoked when patients display equal performance and increased neural activity in comparison to healthy controls. According to the compensatory hypothesis increased activity allows the brain to maintain cognitive performance despite underlying neuropathological changes. Due to methodological and pathology-related issues, however, the functional relevance of the increased activity and the specific brain regions involved in the compensatory response remain unclear. An experimental approach that allows a transient induction of compensatory responses in the healthy brain could help to overcome these issues. To this end we used the nonselective beta-blocker propranolol to pharmacologically induce sub-optimal noradrenergic signaling in healthy participants. In two independent fMRI experiments participants received either placebo or propranolol before they underwent a cognitive challenge (experiment 1: working memory; experiment 2: emotional learning: Pavlovian fear conditioning. In experiment 1 propranolol had no effects on working memory performance, but evoked stronger activity in the left inferior frontal gyrus (IFG. In experiment 2 propranolol produced no effects on emotional memory formation, but evoked stronger activity in the right IFG. The present finding that sub-optimal beta-adrenergic signaling did not disrupt performance and concomitantly increased IFG activity is consistent with, and extends, current perspectives on functional compensation. Together, our findings suggest that under conditions of impaired noradrenergic signaling, heightened activity in brain regions located within the cognitive control network, particularly the IFG, may reflect compensatory operations subserving the maintenance of behavioral performance.

    2006-02-01

    Full Text Available Abstract Background Restriction enzymes are one of the everyday tools used in molecular biology. The continuously expanding panel of known restriction enzymes (several thousands renders their optimal use virtually impossible without computerized assistance. Several manufacturers propose on-line sites that assist scientists in their restriction enzyme work, however, none of these sites meet all the actual needs of laboratory workers, and they do not take into account the enzymes actually present in one's own laboratory. Results Using FileMaker Pro, we developed a stand-alone application which can run on both PCs and Macintoshes. We called it REtools, for Restriction Enzyme tools. This program, which references all currently known enzymes (>3500, permits the creation and update of a personalized list of restriction enzymes actually available in one's own laboratory. Upon opening the program, scientists will be presented with a user friendly interface that will direct them to different menus, each one corresponding to different situations that restriction enzyme users commonly encounter. We particularly emphasized the ease of use to make REtools a solution that laboratory members would actually want to use. Conclusion REtools, a user friendly and easily customized program to organize any laboratory enzyme stock, brings a software solution that will make restriction enzyme use and reaction condition determination straightforward and efficient. The usually unexplored potential of isoschizomers also becomes accessible to all, since REtools proposes all possible enzymes similar to the one(s chosen by the user. Finally, many of the commonly overlooked subtleties of restriction enzyme work, such as methylation requirement, unusual reaction conditions, or the number of flanking bases required for cleavage, are automatically provided by REtools.

    Full Text Available Adult skin stem cells are recognized as potential therapeutics to rejuvenate aged skin. We previously demonstrated that human dermal stem/progenitor cells (hDSPCs with multipotent capacity could be enriched from human dermal fibroblasts using collagen type IV. However, the effects of hDSPCs on cellular senescence remain to be elucidated. In the present study, we investigated whether conditioned medium (CM collected from hDSPC cultures (hDSPC-CM exhibits beneficial effects on senescent fibroblasts. We found that hDSPC-CM promoted proliferation and decreased the expression level of senescence-associated β-galactosidase in senescent fibroblasts. In addition, p53 phosphorylation and p21 expression were significantly reduced in senescent fibroblasts treated with hDSPC-CM. hDSPC-CM restored the expression levels of collagen type I, collagen type III, and tissue inhibitor of metalloproteinase, and antagonized the increase of matrix metalloproteinase 1 expression. Finally, we demonstrated that hDSPC-CM significantly reduced reactive oxygen species levels by specifically up-regulating the expression level of superoxide dismutase 2. Taken together, these data suggest that hDSPC-CM can be applied as a potential therapeutic agent for improving human aged skin.

  19. Vitrification in human and domestic animal embryology: work in progress.

    Vajta, Gábor

    2013-01-01

    According to the analysis of papers published in major international journals, rapidly increasing application of vitrification is one of the greatest achievements in domestic animal and especially human embryology during the first decade of our century. This review highlights factors supporting or hampering this progress, summarises results achieved with vitrification and outlines future tasks to fully exploit the benefits of this amazing approach that has changed or will change many aspects of laboratory (and also clinical) embryology. Supporting factors include the simplicity, cost efficiency and convincing success of vitrification compared with other approaches in all species and developmental stages in mammalian embryology, while causes that slow down the progress are mostly of human origin: inadequate tools and solutions, superficial teaching, improper application and unjustified concerns resulting in legal restrictions. Elimination of these hindrances seems to be a slower process and more demanding task than meeting the biological challenge. A key element of future progress will be to pass the pioneer age, establish a consensus regarding biosafety requirements, outline the indispensable features of a standard approach and design fully-automated vitrification machines executing all phases of the procedure, including equilibration, cooling, warming and dilution steps.

    Aiming at developing exhaust gas driving automobile air conditioning systems, a hydride pair LaNi4.61Mn0.26A10.13/La0.6Y0.4Ni4.8Mn0.2 was developed working at 393~473 K/293~323 K/263~273 K. Property tests showed that both alloys have flat plateau slopes and small hystereses; system theoretical coefficient of performance (COP) is 0.711. Based on this work pair, a function proving automobile metal hydride refrigeration system was constructed. The equivalent thermal conductivities of the activated reaction beds were merely 1.1~1.6 W/(m·K), which had not met practical requirement. Intermittent refrigeration cycles were achieved and the average cooling power was 84.6 W at 423 K/303 K/273 K with COP being 0.26. By altering cycling parameters, experiment data showed that cooling power and system COP increase with the growth of heat source temperature as well as pre-heating and regeneration time while decrease with heat sink temperature increment. This study confirms the feasibility of automobile metal hydride refrigeration systems, while heat transfer properties of reaction beds still need to be improved for better performance.

    Empirical research on happiness took off in the 1970s and accelerated after the emergence of positive psychology by 2000. Today this has resulted in some 23,000 research findings. In this article, I take stock of the findings on social conditions for happiness and distinguish between conditions at the macro level of society, the meso level of organisations and the micro level of individual conditions. A new review technique is applied, an online findings archive is used, in which research findings on happiness are described in a uniform way and sorted by subject. © 2015 International Union of Psychological Science.

    Full Text Available This paper fully describes the working principle of slide valves in single-screw expanders (SSEs. A geometric analysis of suction and volume ratio slide valves is presented to determine the relations between volume ratio, suction closure volume, discharge opening volume and slide valves displacement. An organic Rankine cycle (ORC thermodynamic model with SSE integrated with slide valves is developed to analyze the power output of SSE and the net power output of ORC system and variation law of slide valves displacement. Analysis of a typical ORC system under changing operating conditions shows that the power output of the expander and the net output power of the ORC system with slide valves are much better than those without slide valves. When the condensing temperature is 40 °C and the waste availability is 80 kW, the increase in output power and net output power are approximately 3.4 kW and 5 kW, respectively. The presented geometric analysis of slide valves and the thermodynamic model integrated with slide valves can be used to provide a theoretical and technical basis for designing the slide valves of SSEs and the control strategies of slide valves under varied operating conditions.

    Full Text Available Adoption of new technology in building inspection works has proven to be very crucial and has improved efficiency and effectiveness in this regards. Tools and techniques in building inspection and condition survey continuously evolved trough times. The tools and techniques adopted mostly first has been successfully applied by others technical field such as civil engineering, manufacturing etc.. As UAS has been successfully adopted by many technical professions such as geotechnical engineering, land surveying, civil engineering etc. a practical use of UAV for building surveying and facilities management yet to explored. The present paper intend to explore the viability of UAS application for building inspection with the advantage it has especially in inspecting and collecting data at difficult to reach area such as roof, ceiling, gutter and recording data for large building complex. With the accurate and comprehensive inspection data collected, perhaps it could guide building surveyors or facilities managers in diagnosing building defect effectively, suggesting possible remedies, solving issues and making decision precisely. The present paper provides a comprehensive review of possible application of small UAS in building inspection and facilities management related uses by reviewing the similar application and identifying their features that suits facilities management’s nature of practice. Challenges faced by building and facilities management organisation to apply UAS in their building condition survey routine that are identifying suitable tools other than normal visual tools to be attached, finalising arrangement on site during inspection and limited skill of existing personnel to deal with the equipments.

    The leakage performance of a brush seal with gaseous working fluids at static and low rotor speed conditions was studied. The leakage results included for air, helium, and carbon dioxide at several bristle/rotor interferences. Also, the effects of packing a lubricant into the bristles and also of reversing the pressure drop across the seal were studied. Results were compared to that of an annular seal at similar operating conditions. In order to generalize the results, they were correlated using corresponding state theory. The brush seal tested had a bore diameter of 3.792 cm (1.4930 in.), a fence height of 0.0635 cm (0.025 in.), and 1800 bristles/cm circumference (4500 bristles/in. circumference). Various bristle/rotor radial interferences were achieved by using a tapered rotor. The brush seal reduced the leakage in comparison to the annular seal, up to 9.5 times. Reversing the pressure drop across the brush seal produced leakage rates approximately the same as that of the annular seal. Addition of a lubricant reduced the leakage by 2.5 times. The air and carbon dioxide data were successfully correlated using corresponding state theory. However, the helium data followed a different curve than the air and carbon dioxide data.

    Full Text Available The paper “Human factors in nuclear power engineering in Polish conditions” focuses on analysis of dynamics of preparing Polish society to build fi rst nuclear power plant in XXI century in Poland. Authors compare experience from constructing nuclear power plant Sizewell B (Great Britain and Sizewell C, which is in preparation phase with polish nuclear power program. Paper includes aspects e.g. of creating nuclear safety culture and social opinion about investment. Human factors in nuclear power engineering are as well important as relevant economical and technical factors, but very often negligible. In Poland where history about Czarnobyl is still alive, and social opinion is created on emotions after accident in Fukushima, human factors are crucial and should be under comprehensive consideration.

    Until now, most large-scale studies of humans have either focused on very specific domains of inquiry or have relied on between-subjects approaches. While these previous studies have been invaluable for revealing important biological factors in cardiac health or social factors in retirement choices, no single repository contains anything like a complete record of the health, education, genetics, environmental, and lifestyle profiles of a large group of individuals at the within-subject level. This seems critical today because emerging evidence about the dynamic interplay between biology, behavior, and the environment point to a pressing need for just the kind of large-scale, long-term synoptic dataset that does not yet exist at the within-subject level. At the same time that the need for such a dataset is becoming clear, there is also growing evidence that just such a synoptic dataset may now be obtainable-at least at moderate scale-using contemporary big data approaches. To this end, we introduce the Kavli HUMAN Project (KHP), an effort to aggregate data from 2,500 New York City households in all five boroughs (roughly 10,000 individuals) whose biology and behavior will be measured using an unprecedented array of modalities over 20 years. It will also richly measure environmental conditions and events that KHP members experience using a geographic information system database of unparalleled scale, currently under construction in New York. In this manner, KHP will offer both synoptic and granular views of how human health and behavior coevolve over the life cycle and why they evolve differently for different people. In turn, we argue that this will allow for new discovery-based scientific approaches, rooted in big data analytics, to improving the health and quality of human life, particularly in urban contexts.

    Successful implementation of Human Papillomavirus (HPV) vaccine in each country can only be achieved from a complementary and synergistic perspective, integrating all the different points of view of the diverse related professionals. It is this context where the Spanish HPV Vaccine Consensus Group (Grupo Español de Consenso sobre la Vacuna VPH, GEC-VPH) was created. GEC-VPH philosophy, objectives and experience are reported in this article, with particular attention to the management of negative publicity and anti-vaccine groups. Initiatives as GEC-VPH--adapted to each country's particular idiosyncrasies--might help to overcome the existing barriers and to achieve wide and early implementation of HPV vaccination.

    Full Text Available Background: Dental profession is susceptible to various postural and nonpostural occupational risks. Aim : To determine knowledge, practice, and condition of work place regarding ergonomic posture among dental students from Bhopal city, Central India. Also to observe any correlation among knowledge, practice, and condition of work place scores. Materials and Methods : A self-administered questionnaire study was conducted among 231 dental students. The questionnaire consisted of three parts: Knowledge, practice, and condition of work place. Analysis of variance was used to compare mean of knowledge, practice of clinical posture, and condition of work place. Pearson′s correlation coefficient has been applied to compute correlation among knowledge, practice, and condition of work place scores. A P value < 0.05 was considered significant for all statistical analyses. Results : We found that 70% of dental students perform torsion of the body and cervical flexion to improve vision and prefer direct vision when working. Only 59% reported that they are working with ergonomically designed dental unit and instruments. Most of them reported that the work stool is not comfortable. Mean knowledge, practice, and condition of work place scores were 3.93 (1.26, 5.01 (1.58, and 2.60 (1.14, respectively. Significant differences between the groups were noted for means of practice scores (P ≤ 0.01. Significant linear correlation was seen between knowledge-practice scores (r = 0.20 (P ≤ 0.01, practice-condition of work place scores (r = 0.14 (P ≤ 0.05, and knowledge-condition of work place scores (r = 0.14 (P ≤ 0.05. Conclusion : The knowledge of ergonomic postural requirements and their clinical application among the dental students surveyed were not satisfactory. A multifactorial approach that includes preventive education, postural and positioning strategies, proper selection, and use of ergonomic equipment should be employed.

  10. Restoring Latent Visual Working Memory Representations in Human Cortex.

    Working memory (WM) enables the storage and manipulation of limited amounts of information over short periods. Prominent models posit that increasing the number of remembered items decreases the spiking activity dedicated to each item via mutual inhibition, which irreparably degrades the fidelity of each item's representation. We tested these models by determining if degraded memory representations could be recovered following a post-cue indicating which of several items in spatial WM would be recalled. Using an fMRI-based image reconstruction technique, we identified impaired behavioral performance and degraded mnemonic representations with elevated memory load. However, in several cortical regions, degraded mnemonic representations recovered substantially following a post-cue, and this recovery tracked behavioral performance. These results challenge pure spike-based models of WM and suggest that remembered items are additionally encoded within latent or hidden neural codes that can help reinvigorate active WM representations.

    In most countries in the EU, national surveys are used to monitor working conditions and health. Since the development processes behind the various surveys are not necessarily theoretical, but certainly practical and political, the extent of similarity among the dimensions covered in these surveys has been unclear. Another interesting question is whether prominent models from scientific research on work and health are present in the surveys--bearing in mind that the primary focus of these surveys is on monitoring status and trends, not on mapping scientific models. Moreover, it is relevant to know which other scales and concepts not stemming from these models have been included in the surveys. The purpose of this paper is to determine (1) the similarity of dimensions covered in the surveys included and (2) the congruence of dimensions of scientific research and of dimensions present in the monitoring systems. Items from surveys representing six European countries and one European wide survey were classified into the dimensions they cover, using a taxonomy agreed upon among all involved partners from the six countries. The classification reveals that there is a large overlap of dimensions, albeit not in the formulation of items, covered in the seven surveys. Among the available items, the two prominent work-stress-models--job-demand-control-support-model (DCS) and effort-reward-imbalance-model (ERI)--are covered in most surveys even though this has not been the primary aim in the compilation of these surveys. In addition, a large variety of items included in the surveillance systems are not part of these models and are--at least partly--used in nearly all surveys. These additional items reflect concepts such as "restructuring", "meaning of work", "emotional demands" and "offensive behaviour/violence & harassment". The overlap of the dimensions being covered in the various questionnaires indicates that the interests of the parties deciding on the questionnaires in

    The present study investigated the relationships between the operator's appraisal of his own work situation and the quality of his own work performance as well as self-reported errors in a nuclear power plant control room. In all, 98 control room operators from two nuclear power units filled out a questionnaire and several diaries during two operational conditions, annual outage and normal operation. As expected, the operators reported higher work demands in annual outage as compared to normal operation. In response to the increased demands, the operators reported that they used coping strategies such as increased effort, decreased aspiration level for work performance quality and increased use of delegation of tasks to others. This way of coping does not reflect less positive motivation for the work during the outage period. Instead, the operators maintain the same positive motivation for their work, and succeed in being more alert during morning and night shifts. However, the operators feel less satisfied with their work result. The operators also perceive the risk of making minor errors as increasing during outage. The decreased level of satisfaction with work result during outage is a fact despite the lowering of aspiration level for work performance quality during outage. In order to decrease relative frequencies for minor errors, special attention should be given to reduce work demands, such as time pressure and memory demands. In order to decrease misinterpretation errors special attention should be given to organizational factors such as planning and shift turnovers in addition to training. In summary, the outage period seems to be a significantly more vulnerable window in the management of a nuclear power plant than the normal power production state. Thus, an increased focus on the outage period and human factors issues, addressing the synergetic effects or work demands, organizational factors and coping resources is an important area for improvement

    The work management process in current fleets of national nuclear power plants is so highly dependent on large technical staffs and quality of work instruction, i.e., paper-based, that this puts nuclear energy at somewhat of a long-term economic disadvantage and increase the possibility of human errors. Technologies like mobile portable devices and computer-based procedures can play a key role in improving the plant work management process, thereby increasing productivity and decreasing cost. Automated work packages are a fundamentally an enabling technology for improving worker productivity and human performance in nuclear power plants work activities because virtually every plant work activity is accomplished using some form of a work package. As part of this year’s research effort, automated work packages architecture is identified and an initial set of requirements identified, that are essential and necessary for implementation of automated work packages in nuclear power plants.

    The epidemiology of listeriosis in England and Wales changed during 2001-2008; more patients ≥60 years of age had bacteremia than in previous years. To investigate these changes, we calculated risk for listeriosis by concurrent condition for non-pregnancy-associated listeriosis cases reported to the national surveillance system in England during 1999-2009. Conditions occurring with L. monocytogenes infection were coded according to the International Classification of Diseases, 10th Revision, and compared with appropriate hospital episode statistics inpatient denominator data to calculate incidence rates/million consultations. Malignancies (especially of the blood), kidney disease, liver disease, diabetes, alcoholism, and age ≥60 years were associated with an increased risk for listeriosis. Physicians should consider a diagnosis of listeriosis when treating patients who have concurrent conditions. Providing cancer patients, who accounted for one third of cases, with food safety information might help limit additional cases.

    The presented design and parameters of a three-phase AC plasma torch with the power up to 500 kW, flow rate of air 30-50 g/s (temperature up to 5000 K) could be used in different plasma chemical processes. Range of measured plasma temperature is 3500-5000 K. The paper presents investigations of the plasma torch operation modes for its application in plasma chemical technologies. Plasma chemical technologies for various purposes (processing, destruction of various wastes, including technological and hazardous waste, conversion or production of chemicals to obtain nanoscale materials, etc.) are very promising in terms of the process efficiency. Their industrial use is difficult due to the lack of inexpensive and reliable plasma torches providing the desired level of temperature, enthalpy of the working gas and other necessary conditions for the process. This problem can be solved using a considered design of a three-phase alternating current plasma torch with power of 150-500 kW with working gas flow rate of 30-50 g/s with mass average temperature up to 5000K on the basis of which an industrial plasma chemical plant can be created. The basis of the plasma torch operation is a railgun effect that is the principle of arc movement in the field of its own current field. Thanks to single supply of power to the arc, arcs forming in the discharge chamber of the plasma torch move along the electrodes under the action of electrodynamic forces resulting from the interaction of the arc current with its own magnetic field. Under the condition of the three-phase supply voltage, arc transits from the electrode to the electrode with change in the anodic and cathodic phases with frequency of 300 Hz. A special feature of this design is the ability to organize the movement of the arc attachment along the electrode, thus ensuring an even distribution of the thermal load and thus achieve long time of continuous operation of the plasma torch. The parameters of the plasma jet of the

    Ethylene oxide (EtO) is a powerful disinfectant and sterilant for heat-sensitive surgical items and instruments. Its use in hospitals constitutes an important source of occupational exposure that is sometimes underestimated, such as in cases of EtO device malfunction when the safety rules of procedure are not strictly followed or when individual or collective protective equipment is lacking. We carried out a descriptive study of the health care workers who were assigned to EtO sterilization units of the Lille University Hospital Centre in Lille, France (n = 16). Before the modification of the sterilization units in the development of a single, central sterilization site, we studied the workplaces, occupational conditions, and work procedures of the health care workers exposed to EtO. The aim was to assess the risk of EtO overexposure of the workers in order to improve workers' health and security in the future sterilization center. The study was based on a physical examination, a questionnaire covering each subject's personal and occupational history, and a complete ocular examination. For occupational conditions, the studies of each workplace were also performed by the occupational physician. Area and personal breathing air samplings were performed at each exposure site. Fourteen of the 16 operators had posterior and anterior subcapsular lens opacities, three of which seemed to be directly and primarily related to occupational exposure; the other ten seemed to be rather common and compatible with age. High levels of EtO exposure were reported in the oldest site (90 parts per million [ppm] during the changing of the gas bottle), where exposure often exceeded French threshold limits (permissible exposure limit: 1 ppm 8-hour time-weighted average (TWA) in air; short-term excursion limit: 5 ppm 15-minute TWA in air), or the current US recommended and legal exposure limits for EtO advocated by the Occupational Safety and Health Administration and the American

    We aimed at determining the functional neuroanatomy of working memory (WM) recognition of musical motifs that occurs while listening to music by adopting a non-standard procedure. Western tonal music provides naturally occurring repetition and variation of motifs. These serve as WM triggers, thus allowing us to study the phenomenon of motif tracking within real music. Adopting a modern tango as stimulus, a behavioural test helped to identify the stimulus motifs and build a time-course regressor of WM neural responses. This regressor was then correlated with the participants' (musicians') functional magnetic resonance imaging (fMRI) signal obtained during a continuous listening condition. In order to fine-tune the identification of WM processes in the brain, the variance accounted for by the sensory processing of a set of the stimulus' acoustic features was pruned from participants' neurovascular responses to music. Motivic repetitions activated prefrontal and motor cortical areas, basal ganglia, medial temporal lobe (MTL) structures, and cerebellum. The findings suggest that WM processing of motifs while listening to music emerges from the integration of neural activity distributed over cognitive, motor and limbic subsystems. The recruitment of the hippocampus stands as a novel finding in auditory WM. Effective connectivity and agglomerative hierarchical clustering analyses indicate that the hippocampal connectivity is modulated by motif repetitions, showing strong connections with WM-relevant areas (dorsolateral prefrontal cortex - dlPFC, supplementary motor area - SMA, and cerebellum), which supports the role of the hippocampus in the encoding of the musical motifs in WM, and may evidence long-term memory (LTM) formation, enabled by the use of a realistic listening condition.

  1. "The Human Condition" as social ontology: Hannah Arendt on society, action and knowledge.

    Science.gov (United States)

    Walsh, Philip

    2011-01-01

    Hannah Arendt is widely regarded as a political theorist who sought to rescue politics from "society," and political theory from the social sciences. This conventional view has had the effect of distracting attention from many of Arendt's most important insights concerning the constitution of "society" and the significance of the social sciences. In this article, I argue that Hannah Arendt's distinctions between labor, work, and action, as these are discussed in "The Human Condition" and elsewhere, are best understood as a set of claims about the fundamental structures of human societies. Understanding Arendt in this way introduces interesting parallels between Arendt's work and both classical and contemporary sociology. From this I draw a number of conclusions concerning Arendt's conception of "society," and extend these insights into two contemporary debates within contemporary theoretical sociology: the need for a differentiated ontology of the social world, and the changing role that novel forms of knowledge play in contemporary society as major sources of social change and order.

    Full Text Available The aim of this paper is to present the work undertaken to support a young person with autistic spectrum conditions (ASC over a period of 6 years and to discuss the results of a holistic intervention strategy which addressed a range of difficulties experienced both in school and in the community. A brief overview of common approaches in the education and care support for individuals with ASC is presented. The discussion highlights and suggests that a holistic approach might be more suitable and effective in achieving a range of positive outcomes in an educational and social context. A mixed method single-subject design was adopted. Several data measurements at three age points were collated to demonstrate progress in the following three areas: (1 Positive Behavior Management, (2 Access to Curriculum Lessons and Community Based Activities (3 Level of Staff Support. Adopting a holistic, person-centered and highly individualized approach where opportunities for choice and control are nurtured and fostered suggests that in the long-term more durable and meaningful outcomes are achieved. The results of this single-subject case study have implications for future design, delivery and implementation of educational and care programs.

In order to establish a proper deformation constitutive equation, the compressive deformation behavior of B210P steel was investigated at temperature from 950° to 1150° and strain rates from 0.1s-1 to 10s-1 on a Gleeble-2000 thermo-simulation machine. Based on the true stress-strain data from flow stress curves, a revised model describing the relationships of the flow stress, strain rate and temperature of B210P steel at elevated temperatures is proposed considering the effect of strain on flow stress. The activation energies have been in the range of 277.740-420.241kJ/mol for different amounts of strain. Finally, the accuracy of the developed constitutive equation has been verified using standard statistical parameters. The results confirm that the developed strain-dependent constitutive equation gives an accurate and precise estimate of the flow stress in the relevant deformation conditions.

    Electrochemical methods such as voltammetry and electrochemical impedance spectroscopy are effective for quantifying solid oxide fuel cell (SOFC) operational performance, but not for identifying and monitoring the chemical processes that occur on the electrodes' surface, which are thought to be strictly related to the SOFCs' efficiency. Because of their high operating temperature, mechanical failure or cathode delamination is a common shortcoming of SOFCs that severely affects their reliability. Infrared thermography may provide a powerful tool for probing in situ SOFC electrode processes and the materials' structural integrity, but, due to the typical design of pellet-type cells, a complete optical access to the electrode surface is usually prevented. In this paper, a specially designed SOFC is introduced, which allows temperature distribution to be measured over all the cathode area while still preserving the electrochemical performance of the device. Infrared images recorded under different working conditions are then processed by means of a dedicated image processing algorithm for quantitative data analysis. Results reported in the paper highlight the effectiveness of infrared thermal imaging in detecting the onset of cell failure during normal operation and in monitoring cathode activity when the cell is fed with different types of fuels.

  5. Detection and classification of alarm threshold violations in condition monitoring systems working in highly varying operational conditions

    All commonly used condition monitoring systems (CMS) enable defining alarm thresholds that enhance efficient surveillance and maintenance of dynamic state of machinery. The thresholds are imposed on the measured values such as vibration-based indicators, temperature, pressure, etc. For complex machinery such as wind turbine (WT) the total number of thresholds might be counted in hundreds multiplied by the number of operational states. All the parameters vary not only due to possible machinery malfunctions, but also due to changes in operating conditions and these changes are typically much stronger than the former ones. Very often, such a behavior may lead to hundreds of false alarms. Therefore, authors propose a novel approach based on parameterized description of the threshold violation. For this purpose the novelty and severity factors are introduced. The first parameter refers to the time of violation occurrence while the second one describes the impact of the indicator-increase to the entire machine. Such approach increases reliability of the CMS by providing the operator with the most useful information of the system events. The idea of the procedure is presented on a simulated data similar to those from a wind turbine.

    At least three serious aspects of problems exist as obstacles for the national economy in Japan to grow or even to maintain its present level: the lack of natural resources, the trends of a decreasing young labor force, and an increase in the shift of domestic business operations to foreign countries. Although top managers make the decisions of product or service planning, or both, work systems designers are also responsible for conserving the resources. An action against the decrease of the young work force is needed to maintain work systems in an operable condition. The business shifts to foreign countries affect all the people, who are losing job opportunities. The present paper presents an approach to reorienting human work systems within the scope of the work systems designers' roles under the circumstance of these social environments. The following discussion is based on the assumptions that work organizations be productive for themselves and the world, effective and efficient for themselves, and contributive to their communities and the world. In essence, an approach to human work systems development should be fair to managers and workers alike. Presented are cases of these work systems as developed along the perspectives mentioned.

    This communication presents some elements which come from the experience feedback at CEA about the conditions for the successful integration of HOF in the nuclear safety analysis. To point out some of these conditions, one of the concepts proposed by Edgar Morin to describe the functioning of "complex" systems: the dialogical principle has been used. The idea is to look for some dialogical pairs. The elements of this kind of pair are both complementary and antagonist to one another. Three dialogical pairs are presented in this communication. The first two pairs are related to the organization of the HOF network and the last one is related to the methods which are used to analyse the working situations. The three pairs are: specialist - non-specialist actors of the network, centralized - distributed human resources in the network and microscopic - macroscopic levels of HOF methods to analyse the working situations. To continuously improve these three dialogical pairs, it is important to keep the differences which exist between the two elements of a pair and to find and maintain a balance between the two elements of the pairs.

    Full Text Available Abstract To develop and characterize a novel cell culture method for the generation of undifferentiated and differentiated human mesenchymal stem cell 3D structures, we utilized the RWV system with a gelatin-based scaffold. 3 × 106 cells generated homogeneous spheroids and maximum spheroid loading was accomplished after 3 days of culture. Spheroids cultured in undifferentiated spheroids of 3 and 10 days retained expression of CD44, without expression of differentiation markers. Spheroids cultured in adipogenic and osteogenic differentiation media exhibited oil red O staining and von Kossa staining, respectively. Further characterization of osteogenic lineage, showed that 10 day spheroids exhibited stronger calcification than any other experimental group corresponding with significant expression of vitamin D receptor, alkaline phosphatase, and ERp60 . In conclusion this study describes a novel RWV culture method that allowed efficacious engineering of undifferentiated human mesenchymal stem cell spheroids and rapid osteogenic differentiation. The use of gelatin scaffolds holds promise to design implantable stem cell tissue of various sizes and shapes for future regenerative treatment.

    2016-03-01

    Full Text Available Precarity is becoming the paradigmatic description of young people’s work conditions in crisis-ridden Greece, but also in other European countries. Focusing on interview data on the work experiences of young adults (18-26 years old, in urban centres of Greece, this study attempts to explore the ways in which informants account for working in precarious conditions and construct agency and subjectivity within these ways of accounting. The analysis drawing on insights from critical discursive social psychology indicates that participants construct precarious work conditions as widespread and banal a by treating precarious work as a sine qua non condition of youth employment, b by considering precarious work as an inherent trait of the Greek job-market, c by considering precarious work as a necessary step on a (biographical path leading to the desired and/or appropriate job, or d by adopting a “there is no other alternative” accounting, representing precarious job conditions as the only alternative to unemployment. The analysis also points out the ways in which participants orient themselves to a dilemma of stake and accountability, being concerned to position themselves as effortful subjects, while they are rhetorically constructing the banal regime of precarious labour. The discussion considers the need to bring into the scope of social and political psychology the specific nuances of precarious labour.

  16. Examining factors involved in stress-related working memory impairments: Independent or conditional effects?

    2015-12-01

    A large and growing body of research demonstrates the impact of psychological stress on working memory. However, the typical study approach tests the effects of a single biological or psychological factor on changes in working memory. The current study attempted to move beyond the standard single-factor assessment by examining the impact of 2 possible factors in stress-related working memory impairments. To this end, 60 participants completed a working memory task before and after either a psychological stressor writing task or a control writing task and completed measures of both cortisol and mind wandering. We also included a measure of state anxiety to examine the direct and indirect effect on working memory. We found that mind wandering mediated the relationship between state anxiety and working memory at the baseline measurement. This indirect relationship was moderated by cortisol, such that the impact of mind wandering on working memory increased as cortisol levels increased. No overall working memory impairment was observed following the stress manipulation, but increases in state anxiety and mind wandering were observed. State anxiety and mind wandering independently mediated the relationship between change in working memory and threat perception. The indirect paths resulted in opposing effects on working memory. Combined, the findings from this study suggest that cortisol enhances the impact of mind wandering on working memory, that state anxiety may not always result in stress-related working memory impairments, and that high working memory performance can protect against mind wandering.

    Inadequate facilities and hygiene at slaughterhouses can result in contamination of meat and occupational hazards to workers. The objectives of this study were to assess current conditions in slaughterhouses in western Kenya and the knowledge, and practices of the slaughterhouse workers toward hygiene and sanitation. Between February and October 2012 all consenting slaughterhouses in the study area were recruited. A standardised questionnaire relating to facilities and practices in the slaughterhouse was administered to the foreperson at each site. A second questionnaire was used to capture individual slaughterhouse workers' knowledge, practices and recent health events. A total of 738 slaughterhouse workers from 142 slaughterhouses completed questionnaires. Many slaughterhouses had poor infrastructure, 65% (95% CI 63-67%) had a roof, cement floor and walls, 60% (95% CI 57-62%) had a toilet and 20% (95% CI 18-22%) had hand-washing facilities. The meat inspector visited 90% (95% CI 92-95%) of slaughterhouses but antemortem inspection was practiced at only 7% (95% CI 6-8%). Nine percent (95% CI 7-10%) of slaughterhouses slaughtered sick animals. Only half of workers wore personal protective clothing - 53% (95% CI 51-55%) wore protective coats and 49% (95% CI 46-51%) wore rubber boots. Knowledge of zoonotic disease was low with only 31% (95% CI 29-33%) of workers aware that disease could be transmitted from animals. The current working conditions in slaughterhouses in western Kenya are not in line with the recommendations of the Meat Control Act of Kenya. Current facilities and practices may increase occupational exposure to disease or injury and contaminated meat may enter the consumer market. The findings of this study could enable the development of appropriate interventions to minimise public health risks. Initially, improvements need to be made to facilities and practices to improve worker safety and reduce the risk of food contamination. Simultaneously, training

    This study aimed to identify factors that chief residents believe impact the teaching of junior residents under normal working conditions and the areas in which they believe education on the role of resident as teacher would be beneficial. Obstetrics and gynaecology (O&G) chief residents were asked to rate the importance of teaching various skills, how often conflict situations arose, and to identify training that would be helpful through a national web-based survey. An e-mail was sent to coordinators of the Residency Review Committee (RRC) O&G residency programmes with a request that they forward the link to their chief residents three times from January through March 2006. Responses were received from 204 postgraduate Year 4 (PGY4) residents (18% of all PGY4 residents) from 133 programmes (54% of all residency programmes) and 33 states. Teaching junior residents how to prioritise patient care and obtain critical information in an emergent situation was considered very to extremely important by 97%. Conflict situations with junior residents were reported to occur between one and five times by 41-58%; an additional 26-28% reported that these situations occurred six or more times. Residents felt it would be helpful to extremely helpful to have training in resolving conflicts that involved patient care (48-59%), as well as in resolving conflict among junior residents, communicating effectively with them and becoming an effective leader (65-78%). The skills that chief residents considered most important to teach junior residents involved direct patient care. Chief residents would like training in how to resolve conflict with, and among, junior residents, and in how to become an effective leader.

    In this paper we propose a new method based on finite element method for solving radiation boundary condition of heat equation inside the human eye and other applications. Using this method, we can solve heat equation inside human eye without need to model radiation boundary condition to a robin boundary condition. Using finite element method we can obtain a nonlinear equation, and finally we use nonlinear algorithm to solve it. The human eye is modeled as a composition of several homogeneous regions. The Ritz method in the finite element method is used for solving heat differential equation. Applying the boundary conditions, the heat radiation condition and the robin condition on the cornea surface of the eye and on the outer part of sclera are used, respectively. Simulation results of solving nonlinear boundary condition show the accuracy of the proposed method.

    This communication presents part of an international project focused on the work of trainers from an ergonomics perspective. The objective is to identify in the French vocational training system the various types of job status of trainers and their impact on working conditions and health. In order to explore this issue, we met with 11 trainers, all volunteers, working in the music or human resources sectors. Semi-structured interviews and transcriptions of two weeks of the trainers' professional schedules form the data collected. The analyses show that trainers have various job statuses as trainers and sometimes hold down several jobs at the same time. These working situations create freedom but lack security. With very long daily or weekly working hours, the relationships with trainees and clients are qualified as both very interesting, but also one of the most difficult aspects of the work. The 11 trainers, who considered themselves to be in good health, do however declare infra-pathological disorders, which they often relate to their working conditions. These findings are discussed with regard to the literature and raise issues relating to ergonomic methods in activity analysis and situated action.

    2001-03-12

    This Work Plan describes the approach that will be used to conduct human health and ecological risk assessments for Amchitka Island, Alaska, which was utilized as an underground nuclear test site between 1965 and 1971. During this period, the U.S. Atomic Energy Commission (now the U.S. Department of Energy) conducted two nuclear tests (known as Long Shot and Milrow) and assisted the U.S. Department of Defense with a third test (known as Cannikin). Amchitka Island is approximately 42 miles long and located 1,340 miles west-southwest of Anchorage, Alaska, in the western end of the Aleutian Island archipelago in a group of islands known as the Rat Islands. Historically including deep drilling operations required large volumes of drilling mud, a considerable amount of which was left on the island in exposed mud pits after testing was completed. Therefore, there is a need for drilling mud pit remediation and risk assessment of historical mud pit releases. The scope of this work plan is to document the environmental objectives and the proposed technical site investigation strategies that will be utilized for the site characterization of the constituents in soil, surface water, and sediment at these former testing sites. Its goal is the collection of data in sufficient quantity and quality to determine current site conditions, support a risk assessment for the site surfaces, and evaluate what further remedial action is required to achieve permanent closure of these three sites that will protect both human health and the environment. Suspected compounds of potential ecological concern for investigative analysis at these sites include diesel-range organics, polyaromatic hydrocarbons, polychlorinated biphenyls, volatile organic compounds, and chromium. The results of these characterizations and risk assessments will be used to evaluate corrective action alternatives to include no further action, the implementation of institutional controls, capping on site, or off-sit e

    Full Text Available Orientation: Awareness of presenteeism-related health conditions is important as the prevalence of these conditions unknowingly influences performance and productivity in organisations.Research purpose: The primary objective of this study was to determine the differences in work engagement levels based on groups of presenteeism-related conditions in employees.Motivation for the study: Awareness of the impact of presenteeism-related conditions on work engagement levels can aid in the crafting of interventions to assist employees who suffer from these conditions, which in turn can boost work engagement levels.Research design, approach and method: Cross-sectional data was collected from an availability sample of employees in the manufacturing sector (N = 3387.Main findings: The results of the multi-group structural equation modelling revealed significant mean differences in work engagement levels between the groups. Practical significance tests revealed significant differences between all the groups. The largest difference was between the group who suffered from no presenteeism-related conditions and the group who suffered from all three conditions included in this study concurrently.Practical/managerial implications: Organisational stakeholders are encouraged to take note of the effects that presenteeism-related health conditions have on work engagement and to consider relevant strategies and interventions to address and alleviate symptoms in order to tend to employee health and obviate the effect on productivity.Contribution: This study found that there were clear practical differences between employees who suffer from the presenteeism-related conditions and those who suffer from none of the conditions. Furthermore, there was also a clear difference when comparing the ‘no condition’ group to a general random sample in which employees might experience some symptoms but not comorbidity.

    Full Text Available Abstract Background The aim of the study was to examine the relationship between psychosocial and other working conditions and body-mass index (BMI in a working population. This study contributes to the approximately dozen investigations of job stress, which have demonstrated mixed positive and negative results in relation to obesity, overweight and BMI. Methods A cross-sectional population-based survey was conducted among working Australians in the state of Victoria. Participants were contacted by telephone from a random sample of phone book listings. Information on body mass index was self-reported as were psychosocial work conditions assessed using the demand/control and effort/reward imbalance models. Other working conditions measured included working hours, shift work, and physical demand. Separate linear regression analyses were undertaken for males and females, with adjustment for potential confounders. Results A total of 1101 interviews (526 men and 575 women were completed. Multivariate models (adjusted for socio-demographics demonstrated no associations between job strain, as measured using the demand/control model, or ERI using the effort/reward imbalance model (after further adjustment for over commitment and BMI among men and women. Multivariate models demonstrated a negative association between low reward and BMI among women. Among men, multivariate models demonstrated positive associations between high effort, high psychological demand, long working hours and BMI and a negative association between high physical demand and BMI. After controlling for the effort/reward imbalance or the demand/control model, the association between physical demand and working longer hours and BMI remained. Conclusion Among men and women the were differing patterns of both exposures to psychosocial working conditions and associations with BMI. Among men, working long hours was positively associated with higher BMI and this association was partly

    recommendations, the method proposed identifies very explicit countermeasures. Improvements require a change in human decisions during equipment design, work planning, or the execution itself. The use of a model of human behavior drawing a distinction between automated skill-based behavior, rule-based 'know......-how' and knowledge-based analysis is proposed for identification of the human decisions which are most sensitive to improvements...

    After World War II (WWII) concern grew about the economic and social development of Third World countries. Most countries in Africa, Asia and the Middle East were European colonies while Latin America, even though independent was completely dominated by the US. These countries are characterized by: 1) a poor majority ruled by a small rich minority; 2) large rural populations migrating to the cities resulting in bottlenecks and unemployment; 3) bad health status with deteriorating nutritional states; 4) large families; 5) low levels of education (2/3 of the women in the world are illiterate and 90% live in 17 countries); 5) high levels of corruption in public positions; 6) governments ruled by a military dictator; 7) women in the lowest positions with limited legal rights. After WWII the Marshall Plan was instituted in developing countries (LDCs) to provide economic aid to development a model that used per capita income to measure a country's progress. During the 70's and 80's this model was questioned and more emphasis was put on the need for social and institutional development before investing in economic development. The World Bank and USAID have been promoting the role of the public sector, a strategy that has lowered inflation but has also affected the poor in many countries. For example, infant mortality in Brazil is higher now than 10 years ago. A wise development policy should recognize the need of LDCs to develop their own models while emphasizing agricultural development rather than industrial. Development is never accomplished until every citizen participates in their community. Improving the status of women is not only a human right but a high priority in achieving development. Women in LDCs only have partial rights--they cannot own land, nor inherit, and are not given any credit. Development is not only increasing the per capita income, it includes improving health, education, nutrition, and the quality of life of all its citizens. International law

    Long duration human space missions, as planned in the Vision for Space Exploration, will not be possible without applying unprecedented levels of automation to support the human endeavors. The automated and robotic systems must carry the load of routine housekeeping for the new generation of explorers, as well as assist their exploration science and engineering work with new precision. Fortunately, the state of automated and robotic systems is sophisticated and sturdy enough to do this work - but the systems themselves have never been human-rated as all other NASA physical systems used in human space flight have. Our intent in this paper is to provide perspective on requirements and architecture for the interfaces and interactions between human beings and the astonishing array of automated systems; and the approach we believe necessary to create human-rated systems and implement them in the space program. We will explain our proposed standard structure for automation and robotic systems, and the process by which we will develop and implement that standard as an addition to NASA s Human Rating requirements. Our work here is based on real experience with both human system and robotic system designs; for surface operations as well as for in-flight monitoring and control; and on the necessities we have discovered for human-systems integration in NASA's Constellation program. We hope this will be an invitation to dialog and to consideration of a new issue facing new generations of explorers and their outfitters.

    To evaluate the relation between the working conditions and the workers' health, particularly the prevalences of obesity, liver disorder and hyperlipidemia, we analyzed physiological examination data and the questionnaire survey about life behaviors and working conditions during the terms of car manufacturing work and car sales work among 61 male subjects. In the physiological examination data, compared with the term of car manufacturing work, the values of body weight, body mass index (BMI), GOT, GPT, gamma-GTP, TG and T-CHO elevated and the prevalences of obesity and liver disorder increased during the term of car sales work. During the term of car sales work, the prevalences of alcohol drinkers and cigarette smokers increased and the changes of food intake behaviors were noted. It was estimated that the changes of food intake behaviors associated with the differences of working conditions contributed increasing number of obesity and liver disorder that was based on fatty liver caused by hyperlipidemia. These results of this study suggested that working conditions associated with the prevalences of obesity, liver disorder and hyperlipidemia were important to conduct the effective health education in the present occupational health administration.

    We investigated cadmium sorption by activated sludge immobilized in 1.5% sodium alginate with 0.5% polyvinyl alcohol. Experiments were conducted in an air-lift type reactor at the constant concentration of biosorbent reaching 5 d.m./dm{sup 3}, at three flow rates: 0.1, 0.25 and 0.5 V/h, and at three concentrations of the inflowing cadmium solution: 10, 25 and 50mg/dm{sup 3}. Analyses determined adsorption capacity of activated sludge immobilized in alginate as well as reactor's work time depending on flow rate and initial concentration of the solution. Results achieved were described with the use of Thomas model. The highest adsorption capacity of the sorbent (determined from the Thomas model), i.e., 200.2mg/g d.m. was obtained at inflowing solution concentration of 50mg/dm{sup 3} and flow rate of 0.1V/h, whereas the lowest one reached 53.69mg/g d.m. at the respective values of 10mg/dm{sup 3} and 0.1 V/h. Analyses were also carried out to determine the degree of biosorbent adsorption capacity utilization at the assumed effectiveness of cadmium removal - at the breakthrough point (C=0.05*C{sub 0}) and at adsorption capacity depletion point (C−0.9*C0). The study demonstrated that the effectiveness of adsorption capacity utilization was influenced by both the concentration and flow rate of the inflowing solution. The highest degree of sorbent capacity utilization was noted at inflowing solution concentration of 50mg/dm{sup 3} and flow rate of 0.1 V/h, whereas the lowest one at the respective values of 10mg/dm{sup 3} and 0.1 V/h. The course of the process under dynamic conditions was evaluated using coefficients of tangent inclination - a, at point C/C{sub 0}=1/2. A distinct tendency was demonstrated in changes of tangent slope a as affected by the initial concentration of cadmium and flow rate of the solution. The highest values of a coefficient were achieved at the flow rate of 0.1 V/h and initial cadmium concentration of 50mg/dm{sup 3}.

    Full Text Available On September 25, 2015, the United Nations General Assembly adopted the Sustainable Development Goals (SDGs as the blueprint for a global partnership for peace, development, and human rights for the period 2016 to 2030. The 2030 agenda follows on the heels of the Millennium Development Goals (MDGs, adopted in 2001, which set the international development agenda for the period 2001 to 2015. This article uses a human rights lens to demonstrate that the MDGs and the SDGs have not addressed full employment and decent work in a manner that is consistent with the Decent Work Agenda of the International Labour Organization and international human rights legal obligations of the UN member countries. It concludes that the new 2030 development agenda sadly aligns with market-based economic growth strategies rather than the realization of the human rights to full employment and decent work for all.
