    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.

  12. The Work Design Method for Human Friendly

    Science.gov (United States)

    Harada, Narumi; Sasaki, Masatoshi; Ichikawa, Masami

    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.

Our work shows that cross-professional collaboration is subject to challenges that arise from stakeholders having conflicting priorities, procedures and personalities......Three core themes are explored in eight papers: Usability work as a human activity, usability practice and methods, and persuasiveness of evaluation results and feedback. We explore how usability work is much more than methods and work procedures, and argue that maturing our understanding....... Such challenges include evaluation results lacking relevance, poor timing of evaluation results, little respect for other disciplines, and difficulties sharing important information about a design.

    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.

    Jela Steinerová

    2001-01-01

    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.

  20. Orbitofrontal contributions to human working memory.

    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.

    2012-01-01

    To determine whether employees with disabilities were initially assigned to jobs with work demands that matched their work capacities. Forty-six employees with various physical, mental, sensory and multiple disabilities working in a sheltered workshop. Physical and psychosocial work capacities were assessed post-offer and pre-placement using the Ergo-Kit and Melba. Work demands of the jobs were determined by workplace assessments with TRAC and Melba and were compared with the work capacities. Of the 46 employees, 25 employees were not physically overloaded. When physical overload occurred, it was most often due to regular lifting. All employees were physically underloaded on six or more work activities, most often due to finger dexterity and manipulation. Almost all employees (n=43) showed psychosocial overload or underload on one or more psychosocial characteristics. Psychosocial overload was most often due to endurance (long-term work performance), while psychosocial underload was most often due to speaking and writing. Despite the assessment of work capacities at job placement, underload and overload occurred on both physical activities and psychosocial characteristics. Assessing both work capacities and work demands before job placement is recommended. At job placement more attention should be paid to overloading due to lifting and long-term work performance.

  2. Supramodal parametric working memory processing in humans.

    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.

  3. Human Sexuality as a Critical Subfield in Social Work

    Directory of Open Access Journals (Sweden)

    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.

  7. 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.

    The aim of this study is to analyze the use of pedagogical psychodrama as a strategy for reflecting on the humanization of health care. Five meetings were held from May to June 2000. In these meetings the following themes were developed: context of work in emergencies; updating of the personal and professional, individual and group reference, and acknowledgement of users. In view of the need of rethinking humanization in emergency care, we consider that the psychodrama approach alerted health professionals for the necessary commitment and responsibility in their work.

    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.

  19. The Work Compatibility Improvement Framework: an integrated perspective of the human-at-work system.

    Genaidy, Ash; Salem, Sam; Karwowski, Waldemar; Paez, Omar; Tuncel, Setenay

    2007-01-15

    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.

    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.

    We often draw an analogy between human memory and computers. Information around us is taken into our memory storage first, and then we use the information in storage whatever we need it in our daily life. Linguistic information is also in storage and we process our thoughts based on the memory that is stored. Memory storage consists of multiple memory systems; one of which is called working memory that includes short-term memory. Working memory is the central system that underpins the process...

    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

    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

    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

    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

    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.

  12. 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.

    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.

    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.

    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.

    Barnes, Christopher M; Jiang, Kaifeng; Lepak, David P

    2016-02-01

    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.

    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

    Full Text Available Cognitive overload or underload results in a decrease in human performance which may result in fatal incidents while driving. We envision that driver assistive systems which adapt their functionality to the driver’s cognitive state could be a promising approach to reduce road accidents due to human errors. This research attempts to predict variations of cognitive working memory load levels in a natural driving scenario with multiple parallel tasks and to reveal predictive brain areas. We used a modified version of the n-back task to induce five different working memory load levels (from 0-back up to 4-back forcing the participants to continuously update, memorize, and recall the previous ‘n’ speed sequences and adjust their speed accordingly while they drove for approximately 60 min on a highway with concurrent traffic in a virtual reality driving simulator. We measured brain activation using multichannel whole head, high density functional near-infrared spectroscopy (fNIRS and predicted working memory load level from the fNIRS data by combining multivariate lasso regression and cross-validation. This allowed us to predict variations in working memory load in a continuous time-resolved manner with mean Pearson correlations between induced and predicted working memory load over 15 participants of 0.61 [standard error (SE 0.04] and a maximum of 0.8. Restricting the analysis to prefrontal sensors placed over the forehead reduced the mean correlation to 0.38 (SE 0.04, indicating additional information gained through whole head coverage. Moreover, working memory load predictions derived from peripheral heart rate parameters achieved much lower correlations (mean 0.21, SE 0.1. Importantly, whole head fNIRS sampling revealed increasing brain activation in bilateral inferior frontal and bilateral temporo-occipital brain areas with increasing working memory load levels suggesting that these areas are specifically involved in workload

    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.

    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.

    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.

    Sprague, Thomas C; Ester, Edward F; Serences, John T

    2016-08-03

    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.

    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.

    Full Text Available Today, human resources are considered as the most important assets of any organization. Generally, human being has specific ethical features on personality characteristics forming the attitude, speech and behavior. It is possible that some factors create different attitudes, speech and behavior among people who are in one particular position. These human characteristics influence the efficiency and effectiveness of organization. The present study aims to investigate the relationship between work ethics and human resources productivity in banking network of city of Zahedan, Iran. The study chooses a sample of 236 employees who worked for different banks in city of Zahedan, Iran in 2013. To analyze the data, Pearson correlation test, Friedman ranking and independent t-test were used. The results show that there was a significant association between work ethics components and productivity (efficiency and effectiveness of human resources.

    Baroff, Lynn; Dischinger, Charlie; Fitts, David

    2009-01-01

    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.

    Diane F. Frey

    2016-06-01

    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.

    The goal of the study reported in this article was to explore the conceptualizations of human rights and human rights practice among students and supervisors in social work field settings. Data were collected from 35 students and 48 supervisors through an online survey system that featured two open-ended questions regarding human rights issues in their agency and human rights practice tasks. Responses suggest that participants encountered human rights issues related to poverty, discrimination, participation/self-determination/autonomy, violence, dignity/respect, privacy, and freedom/liberty. They saw human rights practice as encompassing advocacy, service provision, assessment, awareness of threats to clients' rights, and the nature of the worker-client relationship. These results have implications for the social work profession, which has an opportunity to focus more intently on change efforts that support clients' rights. The study points to the possibilities of expanding the scope of the human rights competency within social work education and addressing the key human rights issues in field education. © 2016 National Association of Social Workers.

    Directory of Open Access Journals (Sweden)

    Rokis Rohaiza

    2014-07-01

    Full Text Available The article discusses some basic issues on work and life based on Islamic and non-religious principles. Work and life are inseparable facets of and for human existence. Work derives from the demands of life, and thus it becomes a responsibility for every individual person. The article attempts to relate some highlighted Qur’anic verses and Hadith with basic occupational values such as honesty, modesty and innovativeness, among others, at workplaces. In the end, it makes an effort to understand the working of the subconscious mind on work to make life worthwhile. The plan for this article is to lay emphasis that the presence of human beings, which includes their mind, energy and whatever they can offer in the forms of work, benefits all. In such a case, not only those humans may be seen as successful in fulfilling the work-needs, but also victorious in completing the life-demands as human beings. “Virtuous workplace” is the most ideal platform for such purpose.

  7. Human rights at work: Physical standards for employment and human rights law.

    Science.gov (United States)

    Adams, Eric M

    2016-06-01

    This review focuses on the human rights dimensions of creating and implementing physical standards for employment for prospective and incumbent employees. The review argues that physical standards for employment engage two fundamental legal concepts of employment law: freedom of contract and workplace human rights. While the former promotes an employer's right to set workplace standards and make decisions of whom to hire and terminate, the latter prevents employers from discriminating against individuals contrary to human rights legislation. With reference to applicable human rights legislative regimes and their judicial interpretation in Canada, the United States, the United Kingdom, and Australia, this review demonstrates the judicial preference for criterion validation in testing mechanisms in the finding of bona fide occupational requirements. With particular attention to the Supreme Court of Canada decision in Meiorin, this review argues that an effective balance between workplace safety and human rights concerns can be found, not in applying different standards to different groups of individuals, but in an approach that holds employers to demonstrating a sufficient connection between a uniform physical standard of employment and the actual minimum requirements to perform the job safety and efficiently. Combined with an employer's duty to accommodate, such an approach to lawful physical standards for employment conceives of worker and public safety and workplace diversity as emanating from a shared concern for human rights.

  8. An Inclusive Design Method for Addressing Human Variability and Work Performance Issues

    Directory of Open Access Journals (Sweden)

    2013-07-01

    Full Text Available Humans play vital roles in manufacturing systems, but work performance is strongly influenced by factors such as experience, age, level of skill, physical and cognitive abilities and attitude towards work. Current manufacturing system design processes need to consider these human variability issues and their impact on work performance. An ‘inclusive design’ approach is proposed to consider the increasing diversity of the global workforce in terms of age, gender, cultural background, skill and experience. The decline in physical capabilities of older workers creates a mismatch between job demands and working capabilities which can be seen in manufacturing assembly that typically requires high physical demands for repetitive and accurate motions. The inclusive design approach leads to a reduction of this mismatch that results in a more productive, safe and healthy working environment giving benefits to the organization and individuals in terms of workforce satisfaction, reduced turnover, higher productivity and improved product quality.

  9. Mechanical work as an indirect measure of subjective costs influencing human movement.

    To descend a flight of stairs, would you rather walk or fall? Falling seems to have some obvious disadvantages such as the risk of pain or injury. But the preferred strategy of walking also entails a cost for the use of active muscles to perform negative work. The amount and distribution of work a person chooses to perform may, therefore, reflect a subjective valuation of the trade-offs between active muscle effort and other costs, such as pain. Here we use a simple jump landing experiment to quantify the work humans prefer to perform to dissipate the energy of landing. We found that healthy normal subjects (N = 8) preferred a strategy that involved performing 37% more negative work than minimally necessary (Pheights. This then required additional positive work to return to standing rest posture, highlighting the cost of this preference. Subjects were also able to modulate the amount of landing work, and its distribution between active and passive tissues. When instructed to land softly, they performed 76% more work than necessary (Pwork, with more of it performed passively through soft tissue deformations (at least 30% in stiff landings vs. 16% preferred). During jump landings, humans appear not to minimize muscle work, but instead choose to perform a consistent amount of extra work, presumably to avoid other subjective costs. The degree to which work is not minimized may indirectly quantify the relative valuation of costs that are otherwise difficult to measure.

  10. Social work practitioners and the human-companion animal bond: a national study.

    Risley-Curtiss, Christina

    2010-01-01

    Extensive research documents powerful relationships between humans and companion animals, and 62 percent of U.S. households report having a companion animal. Social workers are likely to work with individuals and families with companion animals; thus, the inclusion of such animals in both practice and research as a natural extension of social work with humans, and their challenges, coping mechanisms, and resiliency factors, seems called for. Yet there is little in the social work literature that identifies what social workers are doing in this area. Thus, this descriptive study sought to explore nationally what social work practitioners know and are doing in the area of the human and companion animal relationships. Findings include that social work practitioners appear to have basic knowledge of the negative and positive relationships between humans and companion animals. About one-third are including questions about companion and other animals in their intake assessments, and a little less than 25 percent are including companion and other animals in their intervention practice. The vast majority have had no special training or coursework to do so. Implications for these and other findings are discussed, and recommendations for social work research, education, and practice are offered.

    2015-12-01

    Full Text Available Background & objective: Occupational accidents may occur in any types of activities. Carrying out daily activities such as repairing and maintaining are one of the work phases that have high risck. Despite the issuance of work permits or work license systems for controling the risks of non-routine activities, the high rate of accidents during activity indicates the inadequacy of such systems. A main portion of this lacking is attributed to the human errors. Then, it is necessary to identify and control the probable human errors during issuing permits. Methods: In the present study, the probable errors for four categories of working permits were identified using SHERPA method. Then, an expert team analyzed 25500 issued permits during a period of approximately one year. Most of frequent human errors and their types were determined. Results: The “Excavation” and “Entry to confined space” permit possess the most errors. Approximately, 28.5 present of all errors were related to the excavation permits. The implementation error was recognized as the most frequent error for all types of error taxonomy. For every category of permits, about 40% of all errors were attributed to the implementation errors. Conclusion: The results may indicate the weakness points in the practical training of the licensing system. The human error identification methods can be used to predict and decrease the human errors.

    2011-03-01

    To explore factors of human capital related to project success that employees expect from nurse managers. Human capital refers to those resources that managers working with projects possess, such as abilities, knowledge and qualities of character. The data were collected by open interviews (n=14) with nurses, public health nurses and nurse managers working in primary health care and a hospital. Data analysis was carried out using qualitative content analysis. The main factors of human capital related to project success proved to be as follows: (1) management of enthusiastic project culture, (2) management of regeneration and (3) management of emotional intelligence. Future research is needed on the kind of means nurse managers use in human capital management in projects and how they see their possibilities in managing human capital. Human capital management skills should be underlined as an important competence area when recruiting a nurse manager. The success of health care projects cannot be improved only through education or by training of nurse managers; in addition, projects need nurse managers who understand workplace spirituality and have high emotional intelligence. © 2011 The Authors.

    Miller, Matthew James; McGuire, Kerry M; Feigh, Karen M

    2017-06-01

    The design and adoption of decision support systems within complex work domains is a challenge for cognitive systems engineering (CSE) practitioners, particularly at the onset of project development. This article presents an example of applying CSE techniques to derive design requirements compatible with traditional systems engineering to guide decision support system development. Specifically, it demonstrates the requirements derivation process based on cognitive work analysis for a subset of human spaceflight operations known as extravehicular activity. The results are presented in two phases. First, a work domain analysis revealed a comprehensive set of work functions and constraints that exist in the extravehicular activity work domain. Second, a control task analysis was performed on a subset of the work functions identified by the work domain analysis to articulate the translation of subject matter states of knowledge to high-level decision support system requirements. This work emphasizes an incremental requirements specification process as a critical component of CSE analyses to better situate CSE perspectives within the early phases of traditional systems engineering design.

    2015-01-01

    Despite their important role in security, little is known about the energy requirements of working dogs such as odor, explosive and human detection dogs. Previous researchers have evaluated the energy requirements of individual canine breeds as well as dogs in exercise roles such as sprint racing. This study is the first to evaluate the energy requirements of working dogs trained in odor, explosive and human detection. This retrospective study evaluated twenty adult dogs who maintained consistent body weights over a six month period. During this time, the average energy consumption was [Formula: see text] or two times the calculated resting energy requirement ([Formula: see text]). No statistical differences were found between breeds, age or sex, but a statistically significant association (p = 0.0033, R-square = 0.0854) was seen between the number of searches a dog performs and their energy requirement. Based on this study's population, it appears that working dogs have maintenance energy requirements similar to the 1974 National Research Council's (NRC) maintenance energy requirement of [Formula: see text] (National Research Council (NRC), 1974) and the [Formula: see text] reported for young laboratory beagles (Rainbird & Kienzle, 1990). Additional research is needed to determine if these data can be applied to all odor, explosive and human detection dogs and to determine if other types of working dogs (tracking, search and rescue etc.) have similar energy requirements.

The aim of the study was to comparatively assess the behavioural response towards humans in different horse categories, in two seasons. The human-animal relationship was investigated during a year, in two different seasons in working horses (171 in the winter, 168 in the summer, stallions (62 in the winter, 66 in the summer and broodmares and young horses (137 in the winter, 146 in the summer. Using specific methods, the general attitude of the horses was evaluated (apathetic or alert and their reactions (aggressiveness, fear/avoidance, indifference, friendliness to the: (1 assessors’ approach (2 walking besides and (3 the attempt of touching the animal. The data were analyzed using the SPSS statistical software. The value of minimal significance was considered at P 0.05. For the behavioural responses (aggressiveness, fear, indifference or friendly response, statistically significant differences (P < 0.05 were found among the assessed horse categories. The season had no significant influence on the variability of responses in the behavioural tests in none of the horse categories. The results indicate an inadequate human-animal relationship in all the studied horse categories, with negative implications on the welfare of the animals. This problem has low remedial possibilities, because it needs human mentality change of those working with horses.

    Australia has been a global leader in balancing public health law, human rights and HIV. The first National HIV/AIDS Strategy launched in 1989 set the agenda for law reform. The Intergovernmental Committee on AIDS subsequently established a legal working party with one of its key tasks to formulate public health legislation that would protect public health and human rights. The NSW Public Health Act 1991 has provided the framework for managing HIV in NSW over the subsequent decades. Recent changes to criminal law in NSW and opportunities to redefine public health law may affect how HIV transmission risks are managed in the future.

    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.

  18. Frontex Working Arrangements: Legitimacy and Human Rights Concerns Regarding ‘Technical Relationships’

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Practices of extraterritorialisation have become cornerstones of the European Union member states' border control. Most of them are highly dependent on the willingness of third countries to cooperate. An increasingly important phenomenon is that cooperation is secured through relationships established by administrative authorities. This article deals with the challenges arising from the active engagement of Frontex in setting up cooperation structures.It is argued that the so-called working arrangements concluded between Frontex and the respective authorities of third countries, in their current form, show considerable deficiencies from the perspectives of the rule of law, democracy and human rights protection. They are not open to judicial review, the Parliament is not involved in their conclusion and they are not disclosed to the public. Furthermore, the human rights record of cooperating authorities is not considered. Concerns in this respect are frequently attempted to be dispelled by recourse to the 'technical' as opposed to 'political' nature of working arrangements. Likewise, it is assumed that merely 'technical relationships' cannot affect individuals. These arguments are not convincing. Quite the contrary, the political implications of working arrangements and their operation in a highly human rights sensitive field demand conformity with the fundamental values the European Union is based on.

    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.

    Objectives To characterize the peculiarities in the training, exercise, and performance of human talent working in environmental health in Colombia. Method Documentary and database reviews. Surveys and semi-structured interviews. Results Approximately 70 % of professionals in the area of environmental health work in health management, food engineering, environmental engineering, sanitary engineering, veterinary medicine, and pharmaceutical chemistry. 63 % of technologists belong to the field of sanitation technology. Only 20 % of surveyed educational institutions apply the competence approach to training to their students and the identification of occupational characteristics in the labor market is only used at the undergraduate level as a criterion of academic analysis and design. Only 20 % of educational institutions identify educational trends in Colombian and or international environmental health as a contribution to their programs. In prospective practices, the following topics to be strengthened were identified: risk factor identfication, measurement, and control; design and implementation of mechanisms for controlling environmental risks; forms of interdisciplinary work between the natural, social and health sciences; preventative and environmental protection measures and the concept of environment (natural, social, and cultural). Conclusion The human talent currently working in environmental health in the country is concentrated in primary care activities (inspection, monitoring and control) and a large spread exists in mission processes and competences, both professionally and technologically. A lack of coordination between the environmental sector and the education sector can be observed. A great diversity exists among the profiles offered by the different educational programs related to environmental health.

  1. Maintenance energy requirements of odor detection, explosive detection and human detection working dogs

    Full Text Available Despite their important role in security, little is known about the energy requirements of working dogs such as odor, explosive and human detection dogs. Previous researchers have evaluated the energy requirements of individual canine breeds as well as dogs in exercise roles such as sprint racing. This study is the first to evaluate the energy requirements of working dogs trained in odor, explosive and human detection. This retrospective study evaluated twenty adult dogs who maintained consistent body weights over a six month period. During this time, the average energy consumption was $136\\pm 38~\\mathrm{kcal}\\cdot {\\mathrm{BW}}_{\\mathrm{kg}}^{0.75}$136±38kcal⋅BWkg0.75 or two times the calculated resting energy requirement ($\\mathrm{RER}=70~\\mathrm{kcal}\\cdot {\\mathrm{BW}}_{\\mathrm{kg}}^{0.75}$RER=70kcal⋅BWkg0.75. No statistical differences were found between breeds, age or sex, but a statistically significant association (p = 0.0033, R-square = 0.0854 was seen between the number of searches a dog performs and their energy requirement. Based on this study’s population, it appears that working dogs have maintenance energy requirements similar to the 1974 National Research Council’s (NRC maintenance energy requirement of $132~\\mathrm{kcal}\\cdot {\\mathrm{BW}}_{\\mathrm{kg}}^{0.75}$132kcal⋅BWkg0.75 (National Research Council (NRC, 1974 and the $139\\pm 42~\\mathrm{kcal}\\cdot {\\mathrm{BW}}_{\\mathrm{kg}}^{0.75}$139±42kcal⋅BWkg0.75 reported for young laboratory beagles (Rainbird & Kienzle, 1990. Additional research is needed to determine if these data can be applied to all odor, explosive and human detection dogs and to determine if other types of working dogs (tracking, search and rescue etc. have similar energy requirements.

    In this article, it is shown that human work can be understood as a process of creating order, and that order can be seen as a form of information. Since information can be considered as negative entropy, work is associated with energy consumption. Therefore, it is important to investigate the nature of human necessities in more detail in order to meet the desire for comfort through the efficient application of energy. Temporary increases of information cause accelerated increases in entropy. This explains the appearance of living organisms, and the historic development of increasingly complex technology. Through technical progress, repetitive human work is being replaced by automation, so that primarily creative work remains. Now the question arises of how much creative work a human can manage. In addition, one goal of automation should be the reduction of human errors, but in doing so, an optimal balance should be found between supporting the operator both during normal procedures and during unforeseen circumstances.

  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.

    2017-03-01

    Jens Rasmussen's multifaceted legacy includes cognitive work analysis (CWA), a framework for the analysis, design, and evaluation of complex sociotechnical systems. After considering the framework's origins, this paper reviews its progress, predictably covering experimental research on ecological interface design, case studies of the application of CWA to human factors and engineering problems in industry, and methods and modelling tools for CWA. Emphasis is placed, however, on studying the nexus between some of the recent results obtained with CWA and the original field studies of human problem-solving that motivated the framework's development. Of particular interest is a case study of the use of CWA for military doctrine development, a problem commonly regarded as lying outside the fields of human factors and engineering. It is concluded that the value of CWA, even for such diverse problems, is likely to result from its conceptual grounding in empirical observations of patterns of human reasoning in complex systems.

    Care is associated with the nursing actions considering, above all, a group of needs of the nursing team. The objectives of this study were: to characterize situations of (dis) satisfaction of the nursing team at work and analyze their possible implications. Maslow's theory of basic human needs was used to understand the motivational factors, and a qualitative methodology was used applying quantitative techniques. The method consisted of participant observation with registers on a filed diary associated to the application of a questionnaire on 18 participants from the nursing team of a Public Hospital in Rio de Janeiro. The study indicates that the basic needs of the nursing team are compromised, especially safety and physiological needs, which are the most primary. The compromising of the subjects' primary needs implies health hazards and reduced work performance in hospital settings.

    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.

  10. A model of working memory: bridging the gap between electrophysiology and human brain imaging.

    2000-01-01

    Human neuroimaging methods such as positron emission tomography and functional magnetic resonance imaging have made possible the study of large-scale distributed networks in the behaving human brain. Although many imaging studies support and extend knowledge gained from other experimental modalities such as animal single-cell recordings, there have also been a substantial number of experiments that appear to contradict the animal studies. Part of the reason for this is that neuroimaging is an indirect measure of neuronal firing activity, and thus interpretation is difficult. Computational modeling can help to bridge the gap by providing a substrate for making explicit the assumptions and constraints provided from other sources such as anatomy, physiology and behavior. We describe a large-scale model of working memory that we have used to examine a number of issues relating to the interpretation of imaging data. The gating mechanism that regulates engagement and retention of short-term memory is revised to better reflect hypothesized underlying neuromodulatory mechanisms. It is shown that in addition to imparting better performance for the memory circuit, this mechanism also provides a better match to imaging data from working memory studies.

    The human ability to perform transitive inference (TI) is an area of debate from a neurocognitive standpoint. Some studies emphasize a stimulus driven medial-temporal lobe process [Preston, A.R., Shrager, Y., Dudukovic, N.M., Gabrieli, J.D., 2004. Hippocampal contribution to the novel use of relational information in declarative memory. Hippocampus 14, 148-152; Titone, D., Ditman, T., Holzman, P., Eichenbaum, H., Levy, D., 2004. A transitive inference test of relational memory in schizophrenia. Schizophr. Res. 68, 235-247; Van Elzakker, M., O'Reilley, R., Rudy, J., 2003. Transivity, flexibility, conjenctive representation and the hippocampus: an empirical analysis. Hippocampus 13, 334-340] while others emphasize a higher-level frontal lobe strategy that requires the flexible maintenance of information in working memory [Waltz, J., Knowlton, B., Holyoak, K., Boone, K., Mishkin, F., de Menedezes Santos, M., Thomas, C., Miller, B., 1999. A system for relational reasoning in human prefrontal cortex. Psychol. Sci. 10, 119-125]. In two experiments we investigated when and how adults employ different cognitive strategies during TI by evaluating the interaction between task instructions and individual differences in working memory capacity. Participants engaged in a paired discrimination task involving a 6-unit TI hierarchy and were either prior aware, prior unaware or serendipitously aware of the hierarchical relationship among stimulus items. Both prior aware participants and serendipitously aware participants were more likely to engage in a logic-based strategy compared to unaware participants who relied upon stimulus-driven strategies. Individual differences in working memory were associated with the acquisition of awareness in the serendipitously aware group and with the maintenance of awareness in the prior aware group. These findings suggest that the capacity for TI may be supported by multiple neurocognitive strategies, and that the specific strategy employed is

    Science unites theory and practice, but theory is always in advance. Even our works (mentioned above) which are also important for practice and were awarded the State prizes could not be made without preliminary theoretical investigations. It should be said that our works with elaborated methods of therapy and drugs to treat chronic alcoholism, drug addiction, leucosis are rather of theoretical than of practical importance. Some our works which proved that carbon dioxide is the basis of life are also of especially great theoretical value. The paper deals with the investigations devoted to the problems of biochemistry in cattle breeding (the raising of fat content in milk; elaboration of the efficient method of fodder ensilage; raising of milk yield using the drug "Karboxilin"; development of the methods of isolation of crystalline glucose-oxidase and catalase used for clarifying blood) as well as to the problems of biochemistry in medicine (creation of the drug "Microcid", antileucosis drug "Corectin", drugs "Medichronal" and "Medicit" for treating alcoholism and drug addiction, drug "Namacit" for hindering the organism aging). Great attention is given to the problem of relations between the theoretical conception concerning the importance of CO2 in vital activity of human and animal organism and production of new drugs.

    Although researchers traditionally examined the 'risk' characteristics of work settings in health studies, few work models, such as the 'demand-control' and 'motivation-hygiene theory', advocated the study of the positive and the negative aspects of work for the ultimate improvement of work performance. The objectives of the current study were: (a) to examine the positive and negative characteristics of work in the machining department in a small manufacturing plant in the Midwest USA, and, (b) to report the prevalence of musculoskeletal and stress outcomes. A focus group consisting of worker experts from the different job categories in the machining department confirmed the management's concerns. Accordingly, 56 male and female workers, employed in three shifts, were surveyed on the demand/energizer profiles of work characteristics and self-reported musculoskeletal/stress symptoms. On average, one-fourth to one-third of the workers reported 'high' demand, and over 50% of the workers documented 'low' energizers for certain work domains/sub-domains, such as 'physical task content'/'organizational' work domains and 'upper body postural loading'/'time organization' work sub-domains. The prevalence of workers who reported 'high' musculoskeletal/stress disorder cases, was in the range of 25-35% and was consistent with the results of 'high' demands and 'low' energizers. The results of this case study confirm the importance of adopting a comprehensive view for work improvement and sustainable growth opportunities. It is paramount to consider the negative and positive aspects of work characteristics to ensure optimum organizational performance. The Work Compatibility Improvement Framework, proposed in the reported research, is an important endeavor toward the ultimate improvement and sustainable growth of human and organizational performance.

  14. Entering into dialogue with the taboo: Reflective writing in a social work human sexuality course

    Heather Killelea McEntarfer, David Skiba & Sarah A. Robert

    2012-06-01

    Full Text Available This paper examines a unique reflective writing assignment used in an undergraduate social work course on human sexuality. We ask what new understandings reflective writing mediates (Vygotsky, 1978 regarding sexual orientation, gender identity, and gender relations—oft-neglected topics within pre-professional academic programs. One goal for this assignment was to mediate future social workers' abilities to differentiate between thoughts and feelings, and we evaluate the degree to which students did so in their writing. By adapting Hatton and Smith's (1994 framework for analyzing reflective writing, we also distinguish between descriptive and dialogical reflection, identifying and analyzing examples of both within the students' writing. Findings suggest that students engaged primarily in descriptive reflection, but also engaged in some dialogical reflection. We argue that both are useful but that the latter mediates deeper and more useful learning. We present recommendations for enhancing reflective writing assignment design in pre-professional academic programs.

    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 Objective: The paper aims at identifying and assessing the significance of work-life balance determinants between the Youth of highly developed societies and its implications for human resources management on the example of Norway. Research Design & Methods: The research target group consists of 236 respondents recruited among Norwegian tertiary education students. It employed literature analysis, two-stage exploratory research: direct individual in-depth interviews, survey based on a self-administered, web-based questionnaire with single-answer, limited choice qualitative & quantitative, as well as explanatory research (informal moderated group discussions. Findings: The research on perceptions of determinants of quality of life and attractiveness of life strategies shows that in a country with relatively high socio-economic development level, such as Norway, differences in rankings do exist. They can be observed in relevance to both material and non-material QoL determinants. Implications & Recommendations: The study revealed a need for deeper research on individually driven early decision-making of future employees and entrepreneurs. This will result in closer modelling of socio-economic phenomena, including more accurate adaptation to trends on the labour market and creation of new business models. Contribution & Value Added: Research value added comes from the comparison of perceptions of quality of life determinants between countries at various stages of socio-economic development and its implications for human resource management.

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 human upper airway (nasal cavity, pharynx and trachea) filters, heats and humidifies inspired air. Its pressure drop affects the work of breathing (WOB, energy expended to inspire and expire) to a degree which varies from person to person, and which is altered by breathing therapy devices. We report experimental studies using 3D printed models of the upper airway based on CT scans of single individuals (adult and paediatric), and average geometries based on PCA analysis of 150 individuals. Particle Image Velocimetry (PIV), gas concentration and pressure measurements, coupled with CFD simulation. These reveal the details of the washout of CO2 rich exhaled gas, the direction-dependent time-varying pressure drop, and the effect of high-flow nasal therapy (HFNT) on these phenomena. A 1D multi-compartment model is used to estimate the work of breathing. For the first time, soft (compliant) elements have been included in the model airways and show that the assumption of rigid tissue is acceptable for unassisted breathing, but unrealistic for therapy-assisted flows.

    The response of skeletal muscle to unweighting was studied in six healthy males who were subjected to four weeks of lowerlimb suspension. They performed three bouts of 30 consecutive maximal concentric knee extensions, before unloading and the day after (POST 1), 4 days after (POST 2) and 7 weeks after (REC) resumed weight-bearing. Peak torque of each contraction was recorded and work was calculated as the mean of the average peak torque for the three bouts and fatigability was measured as the decline in average peak torque over bouts. Needle biopsies were obtained from m. vastus lateralis of each limb before and at POST 1. Muscle fibre type composition and area, capillarity and the enzyme activities of citrate synthase (CS) and phosphofructokinase (PFK) were subsequently analysed. Mean average peak torque for the three bouts at POST1, POST2 and REC was reduced (P 0.05) in response to unloading. The activity of CS, but not PFK, decreased (P < 0.05) after unloading. The weight-bearing limb showed no changes in the variables measured. The results of this study suggest that this human lowerlimb suspension model produces substantial impairments of work and oxidative capacity of skeletal muscle. The performance decrements are most likely induced by lack of weight-bearing.

    This qualitative study explores whether individuals working within the domestic violence (DV) field in the United States have utilized a human rights framework and identifies potential benefits of this framework. Using the critique and experiences of women of color as a focal point, data were gathered through interviews with key individuals working with national and regional DV and human rights organizations. This article focuses on challenges within the mainstream DV movement and how a human rights approach could potentially ameliorate some of these concerns by supporting a more holistic approach to DV and increasing coalition building and community engagement.

    In humans, theta band (5-7 Hz) power typically increases when performing cognitively demanding working memory (WM) tasks, and simultaneous EEG-fMRI recordings have revealed an inverse relationship between theta power and the BOLD (blood oxygen level dependent) signal in the default mode network during WM. However, synchronization also plays a fundamental role in cognitive processing, and the level of theta and higher frequency band synchronization is modulated during WM. Yet, little is known about the link between BOLD, EEG power, and EEG synchronization during WM, and how these measures develop with human brain maturation or relate to behavioral changes. We examined EEG-BOLD signal correlations from 18 young adults and 15 school-aged children for age-dependent effects during a load-modulated Sternberg WM task. Frontal load (in-)dependent EEG theta power was significantly enhanced in children compared to adults, while adults showed stronger fMRI load effects. Children demonstrated a stronger negative correlation between global theta power and the BOLD signal in the default mode network relative to adults. Therefore, we conclude that theta power mediates the suppression of a task-irrelevant network. We further conclude that children suppress this network even more than adults, probably from an increased level of task-preparedness to compensate for not fully mature cognitive functions, reflected in lower response accuracy and increased reaction time. In contrast to power, correlations between instantaneous theta global field synchronization and the BOLD signal were exclusively positive in both age groups but only significant in adults in the frontal-parietal and posterior cingulate cortices. Furthermore, theta synchronization was weaker in children and was--in contrast to EEG power--positively correlated with response accuracy in both age groups. In summary we conclude that theta EEG-BOLD signal correlations differ between spectral power and synchronization and that

    The clinical application of cell transplantation for severe heart failure is a promising strategy to improve impaired cardiac function. Recently, an array of cell types, including bone marrow cells, endothelial progenitors, mesenchymal stem cells, resident cardiac stem cells, and embryonic stem cells, have become important candidates for cell sources for cardiac repair. In the present study, we focused on the placenta as a cell source. Cells from the chorionic plate in the fetal portion of the human placenta were obtained after delivery by the primary culture method, and the cells generated in this study had the Y sex chromosome, indicating that the cells were derived from the fetus. The cells potentially expressed 'working' cardiomyocyte-specific genes such as cardiac myosin heavy chain 7beta, atrial myosin light chain, cardiac alpha-actin by gene chip analysis, and Csx/Nkx2.5, GATA4 by RT-PCR, cardiac troponin-I and connexin 43 by immunohistochemistry. These cells were able to differentiate into cardiomyocytes. Cardiac troponin-I and connexin 43 displayed a discontinuous pattern of localization at intercellular contact sites after cardiomyogenic differentiation, suggesting that the chorionic mesoderm contained a large number of cells with cardiomyogenic potential. The cells began spontaneously beating 3 days after co-cultivation with murine fetal cardiomyocytes and the frequency of beating cells reached a maximum on day 10. The contraction of the cardiomyocytes was rhythmical and synchronous, suggesting the presence of electrical communication between the cells. Placenta-derived human fetal cells may be useful for patients who cannot supply bone marrow cells but want to receive stem cell-based cardiac therapy.

    More individuals than ever are managing work and family roles, but relatively little research has been done exploring whether boundary preferences help individuals benefit from multiple role memberships. Drawing on Greenhaus and Powell's (2006) work-family enrichment theory, along with Boundary Theory (Ashforth, Kreiner, & Fugate, 2000) and Conservation of Resources Theory (Hobfoll, 2002), we explore the impact of personal characteristics as enablers of work-family enrichment, and in turn, work outcomes relevant to human service workers: turnover intentions and emotional exhaustion. In a 2-wave study of 161 human service employees, we found that individuals high in positive affectivity were more likely to experience both work-to-family and family to-work enrichment, whereas those with preferences toward integration were more likely to experience work-to-family enrichment (but not family to-work enrichment). In turn, work-to-family enrichment (but not family to-work enrichment) was related to lower turnover intentions and emotional exhaustion. Enrichment served as a mediating mechanism for only some of the hypothesized relationships. Implications for theory and practice are discussed.

    The purpose of this study was to gain insight into stakeholder perspectives on barriers and facilitators for return-to-work (RTW). Qualitative methodology with purposive sampling was employed. A total of 55 participants, representing a wide spectrum of stakeholders and industry, were interviewed in individual or group format. Interview transcripts were coded, categorized according to themes, and placed within a framework which reflected the dynamic interaction of individuals and the structural systems or context of those individuals. Findings indicated that perceived barriers to RTW included delays of all types in processing or delivery of information or treatment, and ineffective communication among stakeholders. Facilitators to RTW included establishment of RTW programs in the workplace, effective communication and teamwork, as well as trust and credibility among stakeholders. The interdependence of organizational structures and human interactions was evident in successful RTW programs which emphasized teamwork, early intervention, and communication. Differing stakeholder perspectives, however, especially on issues such as worker attitudes and participation, must be acknowledged and addressed if more injured workers are to be successful in returning to full employment.

    According to Mine Safety and Health Administration (MSHA) data, during 2008-2012 in the U.S., there were, on average, 65 lost-time accidents per year during routine mining and maintenance activities involving remote-controlled continuous mining machines (CMMs). To address this problem, the National Institute for Occupational Safety and Health (NIOSH) is currently investigating the implementation and integration of existing and emerging technologies in underground mines to provide automated, intelligent proximity detection (iPD) devices on CMMs. One research goal of NIOSH is to enhance the proximity detection system by improving its capability to track and determine identity, position, and posture of multiple workers, and to selectively disable machine functions to keep workers and machine operators safe. Posture of the miner can determine the safe working distance from a CMM by way of the variation in the proximity detection magnetic field. NIOSH collected and analyzed motion capture data and calculated joint angles of the back, hips, and knees from various postures on 12 human subjects. The results of the analysis suggests that lower body postures can be identified by observing the changes in joint angles of the right hip, left hip, right knee, and left knee.

    The purpose of this study was to develop a model for an integrated estimation of the functional state of the human organism (FSHO) and an integral estimation of physical factors (PF) for hygienic rating. Tests were performed twice with 3 men in 0.7-clo clothing during 4-hr mental work with 9 combinations of 4 PF: wideband noise (55- 83 dB(A)), whole-body vibration (6 Hz, a(z) = 0.2-1.8 ms(-2)), air temperature (18-30 degrees C), and illumination (1, 3, 5 lx). Thermoregulatory, cardiovascular, and psychophysiological reactions and temporary threshold of hearing (TTS2) shifts were studied. For the integral estimation of PF influence on FSHO the model F(y1,y2..........ym) = f(x1,x2,.......xn) was used, relating both FSHO and PF sets. The most important physiological parameters in creating FSHO are defined and the contribution of individual parameters of FSHO and PF is found.

    The temporal maintenance and subsequent retrieval of information that no longer exists in the environment is called working memory. It is believed that this type of memory is controlled by the persistent activity of neuronal populations, including the prefrontal, temporal, and parietal cortex. For a long time, it has been controversially discussed whether, in working memory, the PFC stores past sensory events or, instead, its activation is an extramnemonic source of top-down control over posterior regions. Recent animal studies suggest that specific information about the contents of working memory can be decoded from population activity in prefrontal areas. However, it has not been shown whether the contents of working memory during the delay periods can be decoded from EEG recordings in the human brain. We show that by analyzing the nonlinear dynamics of EEG oscillatory patterns it is possible to noninvasively decode with high accuracy, during encoding and maintenance periods, the contents of visual working memory information within high-gamma oscillations in the human PFC. These results are thus in favor of an active storage function of the human PFC in working memory; this, without ruling out the role of PFC in top-down processes. The ability to noninvasively decode the contents of working memory is promising in applications such as brain computer interfaces, together with computation of value function during planning and decision making processes.

    Full Text Available Human rights are part of the mission and identity of social work; nonetheless, the topic of human rights is not well represented in the field’s scholarly output. The aim of this study is to provide a profile of the literature in the field of social work covering human rights in recent years. For this reason, a descriptive-observational analysis was performed of the output on human rights in social science journals indexed between 2000 and 2015 in the principal international databases, "Scopus" and "Web of Science". A qualitative analysis permitted establishing four main types of topics. The findings reveal a lack of papers dealing with this subject, the predominance of a theoretical approach over an empirical one, and an Anglo-Saxon hegemony. This subject of study has never been approached before. Hence, innovation is the main contribution of this paper.

    2016-05-06

    It has been suggested that one in five riders will be injured due to a fall from a horse, resulting in severe head or torso injuries. Attempts to reduce injury have primarily focussed on low level risk controls, such as helmets. In comparison, risk mitigation in high risk workplaces and sports is directed at more effective and preventative controls like training, consultation, safe work procedures, fit for purpose equipment and regular Workplace Health and Safety (WHS) monitoring. However, there has been no systematic consideration of the risk-reduction benefits of applying a WHS framework to reducing horse-related risks in workplaces, let alone competition or leisure contexts. In this article, we discuss the different dimensions of risk during human-horse interaction: the risk itself, animal, human and environmental factors and their combinations thereof. We consider the potential of the WHS framework as a tool for reducing (a) situation-specific hazards, and (b) the risks inherent in and arising from human-horse interactions. Whilst most-if not all-horses are unpredictable, the majority of horse-related injuries should be treated as preventable. The article concludes with a practical application of WHS to prevent horse-related injury by discussing effective evidence-based guidelines and regulatory monitoring for equestrian sectors. It suggests that the WHS framework has significant potential not only to reduce the occurrence and likelihood of horse-related human accident and injury, but to enable systematic accident analysis and investigation of horse-related adverse events.

    2016-01-01

    The use of military working dogs (MWDs) in support of military operations has increased dramatically over recent years, as they have proven to be our most reliable deterrent to improvised explosive devices. Healthcare delivery for MWDs in combat presents unique challenges and requires extensive collaboration between veterinarians and human health care providers (HCPs). A successful example is the incorporation of MWD emergency care for nonveterinary HCPs into the Joint Trauma System Clinical Practice Guidelines, which has proven to be a helpful product. Additional challenges that need further solutions include MWDs as patients in human medical treatment facilities (MTFs) and the procurement of appropriate canine blood components in an operational environment. It is often necessary for MWDs to be treated as patients in human MTFs, however, there is no Department of Defense guidance to support this activity. Access to MWD blood products is limited to collection of fresh whole blood in the operational setting. Similar to humans, specific blood component therapy, such as fresh frozen plasma, is often indicated for sick or injured MWDs. Currently there is no formal system in place to deliver any blood products for MWDs or to facilitate collection in theater.

    Many studies have investigated the influence of emotion on memory processes across the human lifespan. Some results have shown older adults (OA) performing better with positive stimuli, some with negative items, whereas some found no impact of emotional valence. Here we tested, in two independent studies, how younger adults (YA) and OA would perform in a visuospatial working memory (VSWM) task with positive, negative, and neutral images. The task consisted of identifying the new location of a stimulus in a crescent set of identical stimuli presented in different locations in a touch-screen monitor. In other words, participants should memorize the locations previously occupied to identify the new location. For each trial, the number of occupied locations increased until 8 or until a mistake was made. In study 1, 56 YA and 38 OA completed the task using images from the International Affective Picture System (IAPS). Results showed that, although YA outperformed OA, no effects of emotion were found. In study 2, 26 YA and 25 OA were tested using facial expressions as stimuli. Data from this study showed that negative faces facilitated performance and this effect did not differ between age groups. No differences were found between men and women. Taken together, our findings suggest that YA and OA's VSWM can be influenced by the emotional valence of the information, though this effect was present only for facial stimuli. Presumably, this may have happened due to the social and biological importance of such stimuli, which are more effective in transmitting emotions than IAPS images. Critically, our results also indicate that the mixed findings in the literature about the influence of aging on the interactions between memory and emotion may be caused by the use of different stimuli and methods. This possibility should be kept in mind in future studies about memory and emotion across the lifespan.

    This article argues that rehabilitation enacts a particular understanding of "the human" throughout therapeutic assessment and treatment. Following Michel Callon and Vololona Rabeharisoa's "Gino's Lesson on Humanity," we suggest that this is not simply a top-down process, but is cultivated in the application and response to biomedical frameworks of human ability, competence, and responsibility. The emergence of the human is at once a materially contingent, moral, and interpersonal process. We begin the article by outlining the basics of the actor-network theory that underpins "Gino's Lesson on Humanity." Next, we elucidate its central thesis regarding how disabled personhood emerges through actor-network interactions. Section "Learning Gino's lesson" draws on two autobiographical examples, examining the emergence of humanity through rehabilitation, particularly assessment measures and the responses to them. We conclude by thinking about how rehabilitation and actor-network theory might take this lesson on humanity seriously. © The Author(s) 2016.

  1. An approach to human work systems development under the circumstances of an aging society and international business operations.

    Ikeda, Y T

    1997-12-01

    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.

  2. Subjective valuation of cushioning in a human drop landing task as quantified by trade-offs in mechanical work.

    Humans can perform motor tasks in a variety of ways, yet often favor a particular strategy. Some factors governing the preferred strategy may be objective and quantifiable, (e.g. metabolic energy or mechanical work) while others may be more subjective and less measurable, (e.g. discomfort, pain, or mental effort). Subjectivity can make it challenging to explain or predict preferred movement strategies. We propose that subjective factors might nevertheless be characterized indirectly by their trade-offs against more objective measures such as work. Here we investigated whether subjective costs that influence human movement during drop landings could be indirectly assessed by quantifying mechanical work performed. When landing on rigid ground, humans typically absorb much of the collision actively by bending their knees, perhaps to avoid the discomfort of stiff-legged landings. We measured how work performed by healthy adults (N=8) changed as a function of surface cushioning for drop landings (fixed at about 0.4m) onto varying amounts of foam. Landing on more foam dissipated more energy passively in the surface, thus reducing the net dissipation required of subjects, due to relatively fixed landing energy. However, subjects actually performed even less work in the dissipative collision, as well as in the subsequent active, positive work to return to upright stance (approximately linear decrease of about 1.52 J per 1 cm of foam thickness). As foam thickness increased, there was also a corresponding reduction in center-of-mass vertical displacement after initial impact by up to 43%. Humans appear to subjectively value cushioning, revealed by the extra work they perform landing without it. Cushioning is thus worth more than the energy it dissipates, in an amount that indicates the subjective discomfort of stiff landings.

  7. Preventing and Investigating Horse-Related Human Injury and Fatality in Work and Non-Work Equestrian Environments: A Consideration of the Workplace Health and Safety Framework

    Science.gov (United States)

    Chapman, Meredith; Thompson, Kirrilly

    2016-01-01

    Simple Summary Attempts to reduce horse-related injuries and fatalities to humans have mostly focused on personal protective equipment like helmets. In organizational contexts, such technical interventions are considered secondary to reducing the frequency and severity of accidents. In this article, we describe the Workplace Health and Safety (WHS) framework that has been associated with reduced risks in industries and organisations. We consider how such a framework could be used to reduce horse-related risks in workplaces, as well as non-work equestrian competition and leisure environments. In this article, we propose that the simplicity and concepts of the WHS framework can provide risk mitigation benefits to both work and non-work equine identities. Abstract It has been suggested that one in five riders will be injured due to a fall from a horse, resulting in severe head or torso injuries. Attempts to reduce injury have primarily focussed on low level risk controls, such as helmets. In comparison, risk mitigation in high risk workplaces and sports is directed at more effective and preventative controls like training, consultation, safe work procedures, fit for purpose equipment and regular Workplace Health and Safety (WHS) monitoring. However, there has been no systematic consideration of the risk-reduction benefits of applying a WHS framework to reducing horse-related risks in workplaces, let alone competition or leisure contexts. In this article, we discuss the different dimensions of risk during human–horse interaction: the risk itself, animal, human and environmental factors and their combinations thereof. We consider the potential of the WHS framework as a tool for reducing (a) situation-specific hazards, and (b) the risks inherent in and arising from human–horse interactions. Whilst most—if not all—horses are unpredictable, the majority of horse-related injuries should be treated as preventable. The article concludes with a practical application of

    To establish a digital research platform based on SolidWorks Simulation, then model and analyze human being's ankle in conditions of valgus and varus. Mimics10.01 was used for geometric reconstruction of the ankle based on the CT data of the foot. The model was meshed and assigned with the material properties in SolidWorks software, then imported to simulation. And the distortion situation of the ankle was simulated and analyzed in conditions of valgus and varus. The three-dimensional finite element model of the ankle established had good geometric similarity and could do mechanics analysis and measurement. The simulating results were turned out to be feasible. The mechanics simulation analysis of the human ankle based on SolidWorks Simulation is a effective and reliable method. It can improve the understanding of the mechanics mechanism and provide theoretical support for the clinic diagnosis and treatment of related diseases.%建立一个基于SolidWorks Simulation的数字化研究平台,对正常人体足踝在外翻和内翻状况下进行有限元建模与分析。用CT扫描图像提取志愿者骨骼边缘轮廓数据,利用软件Mimics10.01进行图象三维重建,再将足踝各骨的点云文件导入到SolidWorks软件,利用网格处理向导及曲面生成向导建立三维实体模型,并在对模型进行内翻与外翻状态下,用SolidWorks中的插件Simulation对足踝部分发生形变的过程进行模拟分析。建立的足踝三维有限元模型具有较好的几何相似性,能够进行力学分析和测量,模拟分析结果经验证是可行的。基于SolidWorks Simulation的人体踝骨模拟力学分析是个有效可靠的方法,能提高对其力学机制的认识,并为临床相关疾患的诊治提供理论支持。

    Full Text Available Purpose: The most popular alternative systems to mass production at an academic level (lean manufacturing, agile manufacturing, flexible customization, mass customization... share many characteristics. Our article identifies an extensive set of alternative practices to mass production; analyzes the classification of practices in categories (Flow, TQM, TPM, Customer Relations, Supplier Relations and Human Resources Practices and analyzes the impact on several human performance indicators such as satisfaction, absenteeism, voluntary turnover, permanent contracts, knowledge, personal & social adjustment activities and integration of workers into ordinary companies. Design/methodology/approach: Survey in sheltered work centers. We use regression analysis in order to prove relations between explicative and criterion variables. Findings: The results of our research allow us to identify that human resource management and customer relationship practices have significant effects on job satisfaction, knowledge, integration into ordinary companies and personal and social adjustment. Research limitations/implications: Data came only from one industry; therefore the results would not be directly generalized to other contexts. Practical implications: Managers in Sheltered work centers can estimate the impact of the deployment of alternative tools to mass production. Originality/value: There are few papers relating lean manufacturing tools and human resources performance indicators. At the same time, there are very few research carried out in sheltered work centers context.

    1982-11-01

    The effects of data display on working places was investigated. Data processing by data display devices is not considered. Important criteria for job contentment is the integration into complex job structures. Corresponding to this principle of organization is team work with a flexible way of labor division which provides the chance and the motivation for a cooperative self controlled working process which give strain caused by data display devices. It is found that in public administration a team with an institutional leadership with primarily social integrative functions is appreciated most.

    The effect of geomagnetic storms at the latitude of Moscow on the electric oscillations of the human brain cerebral cortex was studied. In course of electroencephalogram measurements it was shown that when the voluntary persons at the age of 18-23 years old were performing tasks using a computer during moderate magnetic storm or no later than 24 hrs after it, the value of the coherence function of electric oscillations of the human brain in the frontal and occipital areas in a range of 4.0-7.9 Hz (so-called the theta rhythm oscillations of the human brain) decreased by a factor of two or more, sometimes reaching zero, although arterial blood pressure, respiratory rate and the electrocardiogram registered during electroencephalogram measurements remained within the standard values.

    Rae, Caroline D; Bröer, Stefan

    2015-10-01

    Creatine, a naturally occurring nitrogenous organic acid found in animal tissues, has been found to play key roles in the brain including buffering energy supply, improving mitochondrial efficiency, directly acting as an anti-oxidant and acting as a neuroprotectant. Much of the evidence for these roles has been established in vitro or in pre-clinical studies. Here, we examine the roles of creatine and explore the current status of translation of this research into use in humans and the clinic. Some further possibilities for use of creatine in humans are also discussed.

  5. Environmental changes and human work in the region of the Upper Paraná River floodplain: processes and interactions

    Directory of Open Access Journals (Sweden)

    EA. Tomanik

    Full Text Available The environment and society constitute a complex of elements and interactions. Thus, an understanding of the processes in which the environment and psychosocial elements are involved may not be gained from knowledge of just one isolated variable. Based on such premises, the present paper, which summarizes the results of a series of studies, adopts work relationships as its main focus, but in addition, it has two complementary objectives. One is to present some analyses on the interaction between human actions and the environmental changes that have been taking place in the region of the Upper Paraná River floodplain and in its boundaries. A secondary aim is to show how those two factors have been changing people's working and living conditions and the identity configuration of some of the human groups that live at that site.

    2012-01-01

    The aging workforce is a risk factor for manufacturing industries that contain many jobs with high physical workloads. Thus, ergonomic risk factors have to be avoided in early phases of production planning. This paper introduces a new tool for simulating manual work activities with 3D human models, the so-called emaΦ. For the most part, the emaΦ software is based on a unique modular approach including a number of complex operations that were theoretically developed and empirically validated by means of motion capturing technologies. Using these modules for defining the digital work process enables the production planner to compile human simulations more accurately and much quicker compared to any of the existing modeling tools. Features of the emaΦ software implementation, such as ergonomic evaluation and MTM-time analyses, and the workflow for practical application are presented.

    The relationship of measured or modelled Cd concentrations in soil, house dust and available to plants with human urinary Cd concentrations were assessed in a population living around a Cd/Pb/Zn smelter in the UK. Modelled air concentrations explained 35% of soil Cd variation indicating the smelter contributed to soil Cd loads. Multi-variate analysis confirmed a significant role of biological and life-style factors in determining urinary Cd levels. Significant correlations of urinary Cd with soil, house dust and modelled plant available Cd concentrations were not, however, found. Potential reasons for the absence of clear relationships include limited environmental contact in urban populations; the role of undefined factors in determining exposure; and the limited spatial scope of the survey which did not sample from the full pollution gradient. Further, the absence of any significant relationship indicates that environmental measures provide limited advantage over atmospheric model outputs for first stage human exposure assessment. - Highlights: > Environmental measurements indicate smelter pollution of a surrounding urban area. > Life-style and biology influenced U-Cd more than measured environmental levels. > Limited contact with outdoor environments may limit Cd uptake in urban populations. > Better life-style data could improve the attribution of human Cd exposure routes. > Measured Cd levels provide limited added exposure insight over dispersion models. - Measured and modelled environmental cadmium concentrations provide limited additional explanation of human urinary cadmium concentrations.

  11. Adaptation of blood flow during the rest to work transition in humans.

    Science.gov (United States)

    Shoemaker, J K; Hughson, R L

    1999-07-01

    Beat-by-beat measurements show that limb blood flow rises rapidly and in a biphasic manner at the onset of rhythmic exercise in humans. In this review the time course of change in limb flow with the onset of exercise is described and the mechanisms that may or may not contribute to its regulation are discussed. The pumping action of contracting skeletal muscle appears to form an important regulator of increasing flow with the first contraction. However, evidence from human studies suggests that vasodilation begins with the first contraction. Whether this early dilation is regulated by neural recruitment of motor fibers and/or muscle contraction per se is discussed, but the mechanism(s) remains unclear. Finally, the contribution of endothelial-derived relaxation factors to the exponential increase in flow at the exercise onset is examined. Based on studies in humans with intra-arterial infusion of blocking drugs, neither acetylcholine, nitric oxide, nor prostaglandins appear to be essential for a normal dynamic flow response on going from rest to exercise. Overall, evidence from human studies supports the hypothesis that the rate of increase in blood flow during rhythmic voluntary exercise is closely coupled to motor unit recruitment with dilation beginning at the first contraction.

    Ayurvedic science of life is one of the great contributions of India to the systems of health science. Apart from classical medical works, much information related to this Indian system is found elsewhere in other branches of science, such as Philosophy, Joutishya, Natya, Kavya, etc. Still much Ayurvedic information is clubbed in other compilations meant for general purpose. However, it is unfortunate that not all such works came into lime light; and still remain in the dark for many reasons. Haramekhala written by Mahuka is one such work, which contains Ayurvedic information along with various other themes, such as cosmetics. The author Mahuka lived in Dharanivaraha rajya of central India during Chapa Dynasty in 9(th)-10(th) century A.D. Haramekhala also known as Prayogamala comprises of five Paricchedas written in Prakrita language, later added by translations in Sanskrit called Chaya and foot notes in Sanskrit called Tika. The detail about this book is described in this article.

    Directory of Open Access Journals (Sweden)

    Qijie Zhao

    2012-09-01

    Full Text Available In order to adaptively calibrate the work parameters in the infrared‐TV based eye gaze tracking Human‐Robot Interaction (HRI system, a kind of gaze direction sensing model has been provided for detecting the eye gaze identified parameters. We paid more attention to situations where the user’s head was in a different position to the interaction interface. Furthermore, the algorithm for automatically correcting work parameters of the system has also been put up by defining certain initial reference system states and analysing the historical information of the interaction between a user and the system. Moreover, considering some application cases and factors, and relying on minimum error rate Bayesian decision‐making theory, a mechanism for identifying system state and adaptively calibrating parameters has been proposed. Finally, some experiments have been done with the established system and the results suggest that the proposed mechanism and algorithm can identify the system work state in multi‐ situations, and can automatically correct the work parameters to meet the demands of a gaze tracking HRI system.

    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.

    We review how research on stochastic resonance (SR) in neuroscience has evolved and point out that the previous studies have overlooked the interaction between internal and external noise. We propose a new psychometric function incorporating SR effects, and show that a Bayesian adaptive method applied to the function efficiently estimates the parameters of the function. Using this procedure in visual detection experiments, we provide significant insight into the relationship between internal and external noise in SR within the human brain.

    In 1680, Antonie van Leewenhoek noted compositional differences in his oral and fecal microbiota, pioneering the study of the diversity of the human microbiome. From Leewenhoek to modern successful attempts of changing the gut microbiota landscape to cure disease, there has been an exponential increase in the recognition of our resident microbes as part of ourselves. Thus, the human host and microbiome have evolved in parallel to configure a balanced system in which microbes survive in homeostasis with our innate and acquired immune system, unless disease occurs. A growing number of studies have demonstrated a correlation between the presence/absence of microbial taxa, and some of their functional molecules (i.e. genes, proteins, and metabolites), with health and disease states. Nevertheless, misleading experimental design on human subjects, and the cost and lack of standardized animal models pose challenges to answering the question of whether changes in the microbiome composition are cause or consequence of a certain biological state. In this review, we evaluate the state of the art of methodologies that enable the study of the gut microbiome, encouraging a change in broadly used analytic strategies by choosing effector molecules (proteins, metabolites) in combination with coding nucleic acids. We further explore microbial and effector microbial products imbalances that relate to disease and health. Copyright © 2017 American Society for Microbiology.

    Characterizing the quasi-stiffness and work of lower extremity joints is critical for evaluating human locomotion and designing assistive devices such as prostheses and orthoses intended to emulate the biological behavior of human legs. This work aims to establish statistical models that allow us to predict the ankle quasi-stiffness and net mechanical work for adults walking on level ground. During the stance phase of walking, the ankle joint propels the body through three distinctive phases of nearly constant stiffness known as the quasi-stiffness of each phase. Using a generic equation for the ankle moment obtained through an inverse dynamics analysis, we identify key independent parameters needed to predict ankle quasi-stiffness and propulsive work and also the functional form of each correlation. These parameters include gait speed, ankle excursion, and subject height and weight. Based on the identified form of the correlation and key variables, we applied linear regression on experimental walking data for 216 gait trials across 26 subjects (speeds from 0.75-2.63 m/s) to obtain statistical models of varying complexity. The most general forms of the statistical models include all the key parameters and have an R(2) of 75% to 81% in the prediction of the ankle quasi-stiffnesses and propulsive work. The most specific models include only subject height and weight and could predict the ankle quasi-stiffnesses and work for optimal walking speed with average error of 13% to 30%. We discuss how these models provide a useful framework and foundation for designing subject- and gait-specific prosthetic and exoskeletal devices designed to emulate biological ankle function during level ground walking.

    Full Text Available The aim of this study is to discuss the role of human values and relations in the employment of people with work-relevant disabilities. Purpose: Finding and maintaining a paid job is known to be more difficult for people with a disability. The aim of the study is to explore the use which people with a disability make of their private and professional network in finding and maintaining a paid job and the role values play in these relations. This was placed in the context of three complementary perspectives: a perspective that stresses the importance of other than merely rationalistic values, a perspective that stresses the importance of values in work and an interpersonal perspective in which ‘the Other’ is central. Methods: Semi-structured interviews were held with 8 people with a working disability. As well, 4 interviews were held with people from their private network (family and partner and 4 interviews with people from their professional network (colleagues and employers. All interviews were audio-taped and transcribed verbatim. A framework analysis was used to identify the different values in the interviews. This was done with use of MAXqda. Results: The interviews showed that both romantic and rational values and arguments were mentioned by the employers in the context of hiring people with a work-relevant disability; they need to be willing to adjust. The importance of human relations was emphasised in the values mentioned by the respondents when talking about having a paid job. Moreover, ‘the Other’ played an important role in the employment process of people with a work-relevant disability. People with such a disability asked their private network to help them and to provide emotional support. Conclusion: Enabling values and relations had more chance if they were in line with the mission and central value of the organisation. This was one of the first studies on the role that human values and relations play in maintaining a paid

  9. Preventing and Investigating Horse-Related Human Injury and Fatality in Work and Non-Work Equestrian Environments: A Consideration of the Workplace Health and Safety Framework

    Full Text Available It has been suggested that one in five riders will be injured due to a fall from a horse, resulting in severe head or torso injuries. Attempts to reduce injury have primarily focussed on low level risk controls, such as helmets. In comparison, risk mitigation in high risk workplaces and sports is directed at more effective and preventative controls like training, consultation, safe work procedures, fit for purpose equipment and regular Workplace Health and Safety (WHS monitoring. However, there has been no systematic consideration of the risk-reduction benefits of applying a WHS framework to reducing horse-related risks in workplaces, let alone competition or leisure contexts. In this article, we discuss the different dimensions of risk during human–horse interaction: the risk itself, animal, human and environmental factors and their combinations thereof. We consider the potential of the WHS framework as a tool for reducing (a situation-specific hazards, and (b the risks inherent in and arising from human–horse interactions. Whilst most—if not all—horses are unpredictable, the majority of horse-related injuries should be treated as preventable. The article concludes with a practical application of WHS to prevent horse-related injury by discussing effective evidence-based guidelines and regulatory monitoring for equestrian sectors. It suggests that the WHS framework has significant potential not only to reduce the occurrence and likelihood of horse-related human accident and injury, but to enable systematic accident analysis and investigation of horse-related adverse events.

    We demonstrate that common genetic polymorphisms contribute to the increasing heterogeneity of cognitive functioning in old age. We assess two common Val/Met polymorphisms, one affecting the Catechol-O-Methyltransferase (COMT) enzyme, which degrades dopamine (DA) in prefrontal cortex (PFC), and the other influencing the brain-derived neurotrophic factor (BDNF) protein. In two tasks (Wisconsin Card Sorting and spatial working memory), we find that effects of COMT genotype on cognitive performance are magnified in old age and modulated by BDNF genotype. Older COMT Val homozygotes showed particularly low levels of performance if they were also BDNF Met carriers. The age-associated magnification of COMT gene effects provides novel information on the inverted U-shaped relation linking dopaminergic neuromodulation in PFC to cognitive performance. The modulation of COMT effects by BDNF extends recent evidence of close interactions between frontal and medial-temporal circuitries in executive functioning and working memory. PMID:18958202

    Globalization brings along complexity, competition and change as anticipated by working in teams, quality enhancement of human resources and a change of mind-set to be more holistic in approaches. Enhancement of expertise, widening of the horizon, developing added values as well as preparedness to carry out management of the future have to be built and developed. Conditioning and customizing programs through formal and informal education and training should also be carried out in bridging existing gaps, filling needs and solving key problems. New proper and appropriate curricula must be developed together with encouraging the change of mind-set. It is essential to attain the highest capabilities to work in a team and to think and act holistically, as well as to enhance human relations capabilities in communicating the research results. By so doing, the gaps between research and implementation and between theory and practice need to be bridged; the felt real needs of the target groups could thus be filled; and the root causes of the problems faced in any activity could be solved in a sustainable manner. In implementation, a SHIP (Systemic, Holistic, Interdisciplinary and Participatory) approach must be conducted for identifying, analyzing and solving the problems so as to attain sustainable results. In defining the technology being used, it must be comprehensively assessed through six criteria so that it can be technically, economically, ergonomically and socio-culturally sound, save energy and preserve the environment. Through this total approach, work organization and work systems and their products are expected to be more humane (healthier, safer, comfortable, efficient), competitive and sustainable, as prerequisites for survival and continual development.

    2013-12-01

    Full Text Available The agricultural exploitations are often characterized by major changes, by priorities which many times are conflicting, by pressures for obtaining results. The manager has to reduce the costs, has to be all the time informed about the technological progresses and to understand the dynamic of the fast changes of the market and of the clients demand. The success or failure of an agricultural exploitation is related to the way of acting of its employees. The managers can hide in the apparent security of their “bunker” from where they can give orders. In the present time they have to be conscious that they con no longer use the authority and the coercion as it happened once. This is the reason why the word implication characterizes the solution applied in this context. The managers must motivate the employees, inspiring the commitment and the desire for action and encouraging the creativity, they have to exploit the experience, the energy and the skills of different employee groups and to build first class teams for solving the problems, for identifying the opportunities and for give sense to the huge volume of information which is available today. The role of the manager of an agricultural exploitation is not that to make the employees work but to make them work well, to determine them to use all their intellectual and physical resources. Where there is motivation, there is also productivity and performance and the employees are happy.

    Control of genital ulcer disease (GUD) is a proposed intervention to slow the dissemination of human immunodeficiency virus (HIV) infection. Programs for the control of sexually transmitted diseases (STD) should focus on groups of high-frequency transmitters, such as prostitutes and their clientele. This study illustrates the interaction between the prevalence of chancroid, use of barrier prophylaxis against STDs, and HIV infection in a population of female prostitutes in Nairobi. Four hundred and twenty three women were evaluated. Despite the increased use of condoms, the prevalence of genital ulcers remained constant between 1986-87 and 1987-88. Genital ulcer disease was simultaneously associated with HIV infection (adjusted odds ratio: 3.7, P less than .01) whereas it was independently and inversely associated with more consistent condom use (P less than .01). The authors conclude that genital ulcer disease can be controlled in these populations but concurrent HIV infection increases the difficulty of this intervention.

    Full Text Available The paper analyses the intertwining and unity of artistic and scientific ways of human cognition on example of the F. Dostoevsky and A. Ukhtomsky of creativity. Russian literature is characterized by a depth of the person transfer attitude and spiritual aspirations. The works of the great Russian writer Dostoevsky have become one of the sources of scientific heritage of the great Russian scientist Ukhtomsky in discovery of the law of dominants as well as the laws of double and honored companion. Dostoevsky not only the writer but the thinker psychologically accurately has revealed the contradictory nature of human existence, the patterns of the struggle between good and evil in the human soul. Ukhtomsky has used a deep insight about the person of Dostoevsky and organically has bound natural-scientific ideas about behavior with the laws of moral behavior deriving the meaning of human life beyond the natural, purely physiological limits. Dominant determine the direction of internal activity and perception of the world as a whole. The laws of double and honored interlocutor reflect moral self-identity.

    Novel methods and associated tools permitting individual identification in publicly accessible SNP databases have become a debatable issue. There is growing concern that current technical and ethical safeguards to protect the identities of donors could be insufficient. In the context of human embryonic stem cell research, there are no studies focusing on the probability that an hESC line donor could be identified by analyzing published SNP profiles and associated genotypic and phenotypic information. We present the International Stem Cell Forum (ISCF) Ethics Working Party's Policy Statement on "Publishing SNP Genotypes of Human Embryonic Stem Cell Lines (hESC)". The Statement prospectively addresses issues surrounding the publication of genotypic data and associated annotations of hESC lines in open access databases. It proposes a balanced approach between the goals of open science and data sharing with the respect for fundamental bioethical principles (autonomy, privacy, beneficence, justice and research merit and integrity).

    Recent specialized literature about nursing highlighted the causal link among stress, burnout and coping processes. The aim of this study was to evaluate the validity of specific instruments designed to select and manage professional nurses. The instruments studied were: Nurse Stress Index (NSI, Harris, 1989), Maslach Burnout Inventory (MBI, Maslach & Jackson, 1986); Coping Inventory for Stressful Situations (CISS, Endler & Parker, 1990); Job Content Questionnaire (JCQ, Karasek, 1986); and Frequency of Self Reinforcement Questionnaire (FSRQ, Heiby, 1982). 100 professional nurses working in an Institute of Care and Research completed the test battery. Data analysis showed a positive correlation among stress, burnout, emotion-oriented coping, psychophysiological overload and self-undervalue. Classification criteria such as age, sex and professional division moreover highlighted significant differences among nurses. The battery resulted reliable and sensitive in discriminating the different problems linked to nursing and in identifying subjects' personal resources.

    Full Text Available This paper focused on an overview of the different approaches in the literature to the concept of high performance work practices (HPWP, showing how this term evolves over time. Analyzing the literature, the significance of this term are seen as an evolved with customer requirements. Organizations need employees easily adaptable, able to meet customer needs in a timely manner. Therefore, organizations must on the one hand to satisfy their customers, on the other hand, employees, those in which firms can achieve their goals. Currently have placed particular emphasis on employee motivation, training, their involvement in decision making, delegation of authority, remuneration based on performance, rewarding loyalty. All above are considered HPWP and the AMO model is representative of these. The implementation of HPWP is a current problem for organizations wishing to achieve a sustainable competitive advantage. In this sense, this article may provide information of interest to business.

    A NIRS imager is used as a real time monitor in psychological test to record the response in blood oxyhemoglobin state and blood flow of the frontal gyri of human subject. The imager has 9 lamps and 4 dual detector pairs and an area of 9*4 cm. In mental work and pattern recognition test, we recorded oxygen consumption and blood flow changes of the volunteer's frontal gyri. The psychological results showed that down part of the left frontal gyri has intensive relation with pattern recognition and has definite boundaries. However, the mental work involved more zones of frontal gyri and it may be a more complicated think model. The results also suggested that brain have an exquisite and complicated adjust ability. As a result, the oxygen supplement in excited area increased as the neuron excited.

    The human follicular fluid (HFF) contains molecules and proteins that may affect follicle growth, oocyte maturation and competence acquiring. Despite the numerous studies, an integrated broad overview on biomolecular and patho/physiological processes that are proved or supposed to take place in HFF during folliculogenesis and oocyte development is still missing. In this review we report, for the first time, all the proteins unambiguously detected in HFF and, applying DAVID (Database for Annotation, Visualization and Integrated Discovery) and MetaCore bioinformatic resources, we shed new lights on their functional correlation, delineating protein patterns and pathways with reasonable potentialities for oocyte quality estimation in in vitro fertilisation (IVF) programs. Performing a rigorous PubMed search, we redacted a list of 617 unique proteins unambiguously-annotated as HFF components. Their functional processing suggested the occurrence in HFF of a tight and highly dynamic functional-network, which is balanced by specific effectors, primarily involved in extracellular matrix degradation and remodelling, inflammation and coagulation. Metalloproteinases, thrombin and vitamin-D-receptor/retinoid-X-receptor-alpha resulted as the main key factors in the nets and their differential activity may be indicative of ovarian health and oocyte quality. Despite future accurate clinical investigations are absolutely needed, the present analysis may provide a starting point for more accurate oocyte quality estimation and for defining personalised therapies in reproductive medicine.

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

    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.

    Cortical potentials were recorded from implanted electrodes during a difficult working memory task requiring rapid storage, modification and retrieval of multiple memoranda. Synchronous event-related potentials were generated in distributed occipital, parietal, Rolandic and prefrontal sites beginning approximately 130 ms after stimulus onset and continuing for >500 ms. Coherent phase-locked, event-related oscillations supported interaction between these dorsal stream structures throughout the task period. The Rolandic structures generated early as well as sustained potentials to sensory stimuli in the absence of movement. Activation peaks and phase lags between synaptic populations suggested that perceptual processing occurred exclusively in the visual association cortex from approximately 90 to 130 ms, with its results projected to fronto-parietal areas for interpretation from approximately 130 to 280 ms. The direction of interaction then appeared to reverse from approximately 300 to 400 ms, consistent with mental arithmetic being performed by fronto-parietal areas operating upon a visual scratch pad in the dorsolateral occipital cortex. A second reversal, from approximately 420 to 600 ms, may have represented an updating of memoranda stored in fronto-parietal sites. Lateralized perisylvian oscillations suggested an articulatory loop. Anterior cingulate activity was evoked by feedback signals indicating errors. These results indicate how a fronto-centro-parietal 'central executive' might interact with an occipital visual scratch pad, perisylvian articulatory loop and limbic monitor to implement the sequential stages of a complex mental operation.

    Full Text Available The purpose of this study was to examine the integration of indigenous values developed in Turkey to Schwartz’s universal values. Students (N = 593 from six universities in Istanbul responded the value scale, which consists of 10 etic PVQ items (each item representing one of 10 main Schwartz values and 23 emic WAG items (representing work-achievement goals. PROXSCAL, a multidimensional scaling method, was used to test whether etic and emic sets of values integrate and form the universal circular structure proposed in Schwartz value theory. The motivational continuum of values as a circular structure was similar to pan-cultural results, but adding another value type to the openness to change pole. While some of the items in this region represent autonomy of thought, remaining items diverge. The principle of conflicting values on opposite poles was not supported in relation to openness to change-conservation dimension. These two poles had similar priorities, contrasting with pan-cultural results, and demonstrating a culture-specific aspect of responding to motivational goals. Insights gained by emic studies will be functional in enriching understanding values, and contributing to the comprehensiveness and universality of Schwartz value theory.

  5. Human cortical activity evoked by the assignment of authenticity when viewing works of art

    Full Text Available The expertise of others is a major social influence on our everyday decisions and actions. Many viewers of art, whether expert or naïve, are convinced that the full aesthetic appreciation of an artwork depends upon the assurance that the work is genuine rather than fake. Rembrandt portraits provide an interesting image set for testing this idea, as there is a large number of them and recent scholarship has determined that quite a few fakes and copies exist. Use of this image set allowed us to separate the brain's response to images of genuine and fake pictures from the brain's response to external advice about the authenticity of the paintings. Using functional magnetic resonance imaging, viewing of artworks assigned as ‘copy’, rather than ‘authentic’, evoked stronger responses in frontopolar cortex (FPC and right precuneus, regardless of whether the portrait was actually genuine. Advice about authenticity had no direct effect on the cortical visual areas responsive to the paintings, but there was a significant psychophysiological interaction between the FPC and the lateral occipital area, which suggests that these visual areas may be modulated by FPC. We propose that the activation of brain networks rather than a single cortical area in this paradigm supports the art-scholars’ view that aesthetic judgments are multi-faceted and multi-dimensional in nature.

  6. Spatially global representations in human primary visual cortex during working memory maintenance.

    Recent studies suggest that visual features are stored in working memory (WM) via sensory recruitment or sustained stimulus-specific patterns of activity in cortical regions that encode memoranda. One important question concerns the spatial extent of sensory recruitment. One possibility is that sensory recruitment is restricted to neurons that are retinotopically mapped to the positions occupied by the remembered items. Alternatively, specific feature values could be represented via a spatially global recruitment of neurons that encode the remembered feature, regardless of the retinotopic position of the remembered stimulus. Here, we evaluated these alternatives by requiring subjects to remember the orientation of a grating presented in the left or right visual field. Functional magnetic resonance imaging and multivoxel pattern analysis were then used to examine feature-specific activations in early visual regions during memory maintenance. Activation patterns that discriminated the remembered feature were found in regions of contralateral visual cortex that corresponded to the retinotopic position of the remembered item, as well as in ipsilateral regions that were not retinotopically mapped to the position of the stored stimulus. These results suggest that visual details are held in WM through a spatially global recruitment of early sensory cortex. This spatially global recruitment may enhance memory precision by facilitating robust population coding of the stored information.

    Reviews the books, Cold War Social Science: Knowledge Production, Liberal Democracy, and Human Nature by Mark Solovey and Hamilton Cravens (2012) and Working Knowledge: Making the Human Sciences From Parsons to Kuhn by Joel Isaac (see record 2012-13212-000). Taken together, these two important books make intriguing statements about the way to write the histories of fields like psychology, sociology, anthropology, and economics in the Anglo American world during the 20th century. To date, histories of these fields have drawn on a number of fairly well-established punctuation marks to assist in periodization: the shift from interwar institutionalism in economics to postwar neoclassicism, with its physics-like emphasis on mathematical theory-building; the transition from the regnant prewar behaviorism through a postwar "cognitive revolution" in American psychology; and the move in fields like sociology and anthropology away from positivism and the pursuit of what has sometimes been called "grand theory" in the early postwar era toward a period defined by intellectual and political fragmentation, the reemergence of interpretive approaches and a reaction to the scientistic pretensions of the earlier period. These books, by contrast, provide perspectives orthogonal to such existing narrative frameworks by adopting cross-cutting lenses like the "Cold War" and the working practices of researchers in the social and behavioral sciences. As a result, they do much to indicate the value of casting a historiographical net beyond individual disciplines, or even beyond the "social sciences" or the "human sciences" sensu stricto, in the search for deeper patterns of historical development in these fields.

    The main goal of this Nordic Nuclear Safety Research Council (NKS) project is to produce guidance for how to use human reliability analysis (HRA) to strengthen overall safety. The project consists of two substudies: The Nordic Point of View - A User Needs Analysis, and The American Point of View - Insights of How the US Nuclear Industry Works with HRA. The purpose of the Nordic Point of View study was a user needs analysis that aimed to survey current HRA practices in the Nordic nuclear industry, with the main focus being to connect HRA to system design. In this study, 26 Nordic (Swedish and Finnish) nuclear power plant specialists with research, practitioner, and regulatory expertise in HRA, PRA, HSI, and human performance were interviewed. This study was completed in 2009. This study concludes that HRA is an important tool when dealing with human factors in control room design or modernizations. The Nordic Point of View study showed areas where the use of HRA in the Nordic nuclear industry could be improved. To gain more knowledge about how these improvements could be made, and what improvements to focus on, the second study was conducted. The second study is focused on the American nuclear industry, which has many more years of experience with risk assessment and human reliability than the Nordic nuclear industry. Interviews were conducted to collect information to help the author understand the similarities and differences between the American and the Nordic nuclear industries, and to find data regarding the findings from the first study. The main focus of this report is to identify potential HRA improvements based on the data collected in the American Point of View survey. (Author)

  9. The attentional blink reveals serial working memory encoding: evidence from virtual and human event-related potentials.

    Observers often miss a second target (T2) if it follows an identified first target item (T1) within half a second in rapid serial visual presentation (RSVP), a finding termed the attentional blink. If two targets are presented in immediate succession, however, accuracy is excellent (Lag 1 sparing). The resource sharing hypothesis proposes a dynamic distribution of resources over a time span of up to 600 msec during the attentional blink. In contrast, the ST(2) model argues that working memory encoding is serial during the attentional blink and that, due to joint consolidation, Lag 1 is the only case where resources are shared. Experiment 1 investigates the P3 ERP component evoked by targets in RSVP. The results suggest that, in this context, P3 amplitude is an indication of bottom-up strength rather than a measure of cognitive resource allocation. Experiment 2, employing a two-target paradigm, suggests that T1 consolidation is not affected by the presentation of T2 during the attentional blink. However, if targets are presented in immediate succession (Lag 1 sparing), they are jointly encoded into working memory. We use the ST(2) model's neural network implementation, which replicates a range of behavioral results related to the attentional blink, to generate "virtual ERPs" by summing across activation traces. We compare virtual to human ERPs and show how the results suggest a serial nature of working memory encoding as implied by the ST(2) model.

  10. SEX WORK, LAW, AND VIOLENCE: BEDFORD V. CANADA AND THE HUMAN RIGHTS OF SEX WORKERS

    Directory of Open Access Journals (Sweden)

    Full Text Available In Bedford v. Canada, two levels of Ontario courts ruled that a selection of criminal laws prohibiting prostitution-related activities unjustifiably deprive sex workers of their right to liberty and security of the person.The courts struck down or modified some of the offending provisions to ensure that sex workers are better able to take precautions against violence. While sex workers consider the Ontario Superior Court of Justice ruling a victory and the Ontario Court of Appeal ruling a partial victory, the government, some women’s rights groups, and other defenders of the provisions argue that courts ventured into a “policy thicket”, which is to suggest that they had stepped outside of their legitimate institutional role. Associated concerns include that the decisions effectively constitutionalize prostitution and will pre-empt or curtail Parliament’s consideration of legislative options.      In this paper, the authors clarify misconceptions about the constitutional foundations and implications of Bedford, and explore how the ruling might affect legal and policy-based interactions among various stakeholders. Approaching constitutional rights as discursive mechanisms, rather than as “trumps”, we argue that Bedford will not hinder the continuation of democratic debate about whether, how, and why aspects of sex work should be regulated. To the contrary, Bedford is more likely to enhance the quality of debates by making them more inclusive of the perspectives of sex workers as well as accommodative of growing empirical research that has hitherto been ignored or misrecognized.   Dans l’affaire Bedford v. Canada, deux tribunaux ontariens ont conclu que des dispositions législatives du droit criminel interdisant les activités liées à la prostitution privaient de façon injustifiée les travailleurs et travailleuses du sexe du droit à la liberté et à la sécurité de leur personne.

    Full Text Available Abstract Background Much has been written in the past decade about the health workforce crisis that is crippling health service delivery in many middle-income and low-income countries. Countries having lost most of their highly qualified health care professionals to migration increasingly rely on mid-level providers as the mainstay for health services delivery. Mid-level providers are health workers who perform tasks conventionally associated with more highly trained and internationally mobile workers. Their training usually has lower entry requirements and is for shorter periods (usually two to four years. Our study aimed to explore a neglected but crucial aspect of human resources for health in Africa: the provision of a work environment that will promote motivation and performance of mid-level providers. This paper explores the work environment of mid-level providers in Malawi, and contributes to the validation of an instrument to measure the work environment of mid-level providers in low-income countries. Methods Three districts were purposively sampled from each of the three geographical regions in Malawi. A total of 34 health facilities from the three districts were included in the study. All staff in each of the facilities were included in the sampling frame. A total of 153 staff members consented to be interviewed. Participants completed measures of perceptions of work environment, burnout and job satisfaction. Findings The Healthcare Provider Work Index, derived through Principal Components Analysis and Rasch Analysis of our modification of an existing questionnaire, constituted four subscales, measuring: (1 levels of staffing and resources; (2 management support; (3 workplace relationships; and (4 control over practice. Multivariate analysis indicated that scores on the Work Index significantly predicted key variables concerning motivation and attrition such as emotional exhaustion, job satisfaction, satisfaction with the profession

    2014-11-01

    Full Text Available The analysis of the philosophical and narrative structure’s features in the novels by modern Spanish writer A. Pérez-Reverte has been reviewed in this article. His works present an example of the postmodern double coding, that is the compound a mass and elite, playing and moral. It allows to avoid the text’s tendentiousness and to keep the content. In the novel “The Siege” A. Pérez-Reverte uses the detective story, but he deconstructs it: keeping the traditional plot’s scheme the writer changes the images’ interpretation, the meaning of the finale, adds the intertext and the conceptual metaphors (the chess, the net, the herbarium. They code some philosophical ideas about human life. At the same time A. Pérez-Reverte asks the traditional classic literature’s questions and shows how war influences the person, what is love and so on. He also makes a psychological analysis of actions’ reasons and reveal the feelings’ contradictory. As a result, the multilayer, nonlinear and metaphorical narrative has been viewed as a particular tool of the author’s opinion realization and the philosophical implication’s creation. And with it the postmodern polysemic text associates with a psychological analysis and humanism

    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. (Author).

  16. The effect of high performance work systems utilization on firm performance: does human resource attribution of employees matter?

    Directory of Open Access Journals (Sweden)

    Shibiru Ayalew Melesse

    2016-12-01

    Full Text Available A large body of research suggests that high performance work systems (HPWSs that enhance employees’ competencies, and motivate them, leads to competitive advantage. HPWPs are radically not ‘new practices’; they have been around for many years and have already been adopted by various organizations. However, the link between HPWS adoption & firm performance is yet blurred. The aim of this paper was to examine the moderating role of employees’ HR attributions on the relationship between adoption of HPWSs and firm performance. The current paper argues that human resource (HR attribution of employees moderates the relationship between HPWS and firm performance such that the effective adoption of high performance work systems in an organization partly depends on the type of employees’ attributions (commitment versus control of HR practices in the company. More specifically, it is proposed that adoption of HPWS can be more effective in organizations where employees’ attributions of HR practices is commitment focus than in firms where employees’ attributions of HR practice is control focus. The study contributes to understanding the ‘black box’ of HRM-performance link. Theoretical and practical implications and future research directions are discussed.

  17. Factors affecting the appreciation generated through applying human factors/ergonomics (HFE) principles to systems of work.

    2014-01-01

    This retrospective study examined the levels of appreciation (applause) given by clients to Human Factors/Ergonomic (HFE) specialists after they have modified the systems of work. Thirteen non-academic projects were chosen because the HFE interventions involved changed the way workers work at their workplaces. Companies involved range from multi-national corporations and military organizations with thousands of employees to small trading companies with less than 10 employees. In 5 cases the HFE recommendations were fully adopted and well appreciated. In 4 they were largely ignored and not appreciated, with partial adoption and some appreciation in the other 4 cases. Three factors that predict appreciation were identified: (i) alignment between the benefits HFE can provide and the project's key performance indices; (ii) awareness of HFE among the client's senior management; and (iii) a team organization appropriate for applying HFE recommendations. Having an HFE specialist on the client's side can greatly increase levels of appreciation, but lack of such a specialist will not affect levels of appreciation. A clear contractual requirement for HFE intervention does not promote appreciation significantly, but its absence can greatly reduce levels of appreciation. These relationships are discussed using the Kano's model of quality. Means to generate greater appreciation of the benefits of HFE are discussed.

    2016-12-01

    This paper argues that more work is needed to facilitate cross-disciplinary collaborations by scholars across the physical sciences and humanities to improve Data Rescue Activities (DARE). Debate over the scale and potential impact of anthropogenic global warming is one of the dominant narratives of the twenty-first century. Predicting future climates and determining how environment and society might be affected by climate change are global issues of social, economic and political importance. They require responses from different research communities and necessitate closer inter-disciplinary working relationships for an integrated approach. Improving the datasets required for long-term climate models is an important part of this process. Establishing a multi-disciplinary dialogue and approach to DARE activities is increasingly being recognised as the best way to achieve this. This paper focuses on the recovery of the long-term instrumental weather observations used for models and reconstructions of the climate over the past two-hundred years. Written from the perspective of an historian working in the field, it does not seek to explore the reconstructions themselves but the process of data gathering, advocating a closer working relationship between the arts, social sciences, and sciences to extend the geographic and temporal coverage of extant datasets. This is especially important for regions where data gaps exist currently. First, it will offer a justification for extending data recovery activities for Southeast Asia and the China Seas region. Second, it will offer a brief overview of the data recovery projects currently operating in that area and the typesof historic source material that are used. Third, it will explore the work currently being undertaken for Southeast Asia and China under the Atmospheric Circulation Reconstructions over the Earth initiative as an example of a successful cross-disciplinary program. Finally, it will argue the importance of

    Recently, a growing number in Japan are switching to taking baths in the morning (morning bathing). However, the effects of the morning bathing on human physiological functions and work efficiency have not yet been revealed. Then, we hypothesized that the effect of morning bathing on physiological functions would be different from those of night bathing. In this study, we measured the physiological functions and work efficiency during the day following the morning bathing (7:10-7:20) including showering, mist sauna bathing, and no bathing as a control. Ten male healthy young adults participated in this study as the subjects. We evaluated the rectal temperature (Tre), skin temperature (Tsk), heart rate (HR), heart rate variability (HRV), blood pressure (BP), the relative power density of the alpha wave (α-wave ratio) of electroencephalogram, alpha attenuation coefficient (AAC), and the error rate of the task performance. As a result, we found that the HR after the mist sauna bathing was significantly lower than those after no bathing rest 3 (11:00). Furthermore, we verified that the α-wave ratio of the Pz after the mist sauna bathing was significantly lower than those after no bathing during the task 6 (15:00). On the other hand, the α-wave ratio of the Pz after the mist sauna bathing was significantly higher than those after showering during the rest 3 (11:00). Tsk after the mist sauna bathing was higher than those after the showering at 9:00 and 15:00. In addition, the error rate of the task performance after the mist sauna bathing was lower than those after no bathing and showering at 14:00. This study concludes that a morning mist sauna is safe and maintains both skin temperature compared to other bathing methods. Moreover, it is presumed that the morning mist sauna bathing improves work efficiency comparing other bathing methods during the task period of the day following the morning bathing.

    Full Text Available In this study, the studied software as the Product Data Management (PDM provides solutions for helping to control designing data. Users can be sure of storing their own designing data for quick retrieval of data and reducing the concerns about control of edited data and losing data and even sharing and collaborating in online projects with members of local networks. If the designers want to change their way in analyzing every component of mechanical mechanism, the selected component should be studied for the Finite Element Analysis (FEA in order to be analyzed structurally. Finite element analysis is a numerical method for structural analysis and leads to the dominant approach of “Computer Aided Engineering” (CAE for study of structure. Finite element analysis can evaluate a variety of motion, component analysis, stresses and vibrations from the under-load static and dynamic bracket. As the result of motion simulation, the input data, necessary for the structural analysis done by FEA, is provided. Providing the simulation and study of integrated and simultaneous motion is among the features of software SolidWorks. By this feature of Software SolidWorks, the designers will be able to reduce the number of required pilots. This study provides the suggestions for development of designing and working in the field of building the rescue robots for relevant organizations.

    Reports an error in "Do positive affectivity and boundary preferences matter for work-family enrichment? A study of human service workers" by Laurel A. McNall, Lindsay D. Scott and Jessica M. Nicklin (Journal of Occupational Health Psychology, 2015[Jan], Vol 20[1], 93-104). In the article there was an error in Figure 1. The lower left bubble should read "Boundary Preference Toward Segmentation" instead of "Boundary Preference Toward Integration." (The following abstract of the original article appeared in record 2014-44477-001.) More individuals than ever are managing work and family roles, but relatively little research has been done exploring whether boundary preferences help individuals benefit from multiple role memberships. Drawing on Greenhaus and Powell's (2006) work-family enrichment theory, along with Boundary Theory (Ashforth, Kreiner, & Fugate, 2000) and Conservation of Resources Theory (Hobfoll, 2002), we explore the impact of personal characteristics as enablers of work-family enrichment, and in turn, work outcomes relevant to human service workers: turnover intentions and emotional exhaustion. In a 2-wave study of 161 human service employees, we found that individuals high in positive affectivity were more likely to experience both work-to-family and family to-work enrichment, whereas those with preferences toward integration were more likely to experience work-to-family enrichment (but not family to-work enrichment). In turn, work-to-family enrichment (but not family to-work enrichment) was related to lower turnover intentions and emotional exhaustion. Enrichment served as a mediating mechanism for only some of the hypothesized relationships. Implications for theory and practice are discussed. (PsycINFO Database Record

    The purpose of this study was to explore potential influences on marriage and family therapists' comfort level when working with lesbian and gay male clients, including sex, age, race, sexual orientation, political orientation, religious practices of the therapist, as well as the level of support for lesbian and gay male human rights. Participants in this study were 199 experienced therapists. Results indicated that higher levels of religious practices were related to lower levels of support for lesbian and gay male human rights and to lower levels of comfort working with lesbian and gay male clients. When support for lesbian and gay male human rights was considered, the level of religious practices was no longer predictive of comfort working with lesbian and gay male clients.

  7. Negative Facial Expressions – But Not Visual Scenes – Enhance Human Working Memory in Younger and Older Participants

    Directory of Open Access Journals (Sweden)

    Flávia Schechtman Belham

    2017-09-01

    Full Text Available Many studies have investigated the influence of emotion on memory processes across the human lifespan. Some results have shown older adults (OA performing better with positive stimuli, some with negative items, whereas some found no impact of emotional valence. Here we tested, in two independent studies, how younger adults (YA and OA would perform in a visuospatial working memory (VSWM task with positive, negative, and neutral images. The task consisted of identifying the new location of a stimulus in a crescent set of identical stimuli presented in different locations in a touch-screen monitor. In other words, participants should memorize the locations previously occupied to identify the new location. For each trial, the number of occupied locations increased until 8 or until a mistake was made. In study 1, 56 YA and 38 OA completed the task using images from the International Affective Picture System (IAPS. Results showed that, although YA outperformed OA, no effects of emotion were found. In study 2, 26 YA and 25 OA were tested using facial expressions as stimuli. Data from this study showed that negative faces facilitated performance and this effect did not differ between age groups. No differences were found between men and women. Taken together, our findings suggest that YA and OA’s VSWM can be influenced by the emotional valence of the information, though this effect was present only for facial stimuli. Presumably, this may have happened due to the social and biological importance of such stimuli, which are more effective in transmitting emotions than IAPS images. Critically, our results also indicate that the mixed findings in the literature about the influence of aging on the interactions between memory and emotion may be caused by the use of different stimuli and methods. This possibility should be kept in mind in future studies about memory and emotion across the lifespan.

    Full Text Available Brazilian broiler industry adds a significant contribution to country's exports, employing around five million workers in the production chain. The human work involves multiple aspects, including values, beliefs related to work, cultural aspects, personality, motivation etc. The aim of this research was to analyze the associations between broiler accumulated mortality and workers' beliefs related to work, and influences of the supervisors. The study took place in the state of Paraná, Brazil involving 80 broiler integrate farms and 60 workers. A pre-elaborated questionnaire was applied to the workers containing questions related to their health and to some beliefs related to work, as an interview where they could express their feelings. The normal tasks were identified and listed as well as the health status of each worker. The most common group health problems were related to muscle skeletal pain in the lumbar region (53.7% with a weekly frequency, and within the last three months. The low back pain was reported mostly in prevalence of chronic pain, probably due to some manual activities such as cleaning of drinkers and feeders. Statistical analysis revealed four beliefs related to the accumulated broiler mortality: the results depend on me (a; the Company is serious (b; the broilers suffer (c; and training is needed to grow broilers (d. Those beliefs related to work were significant in the model that described the accumulated broiler mortality (ABM as ABM= 3.28 -0.254 a +0.231 b +0.336 c -0.152d.

    2015-01-01

    The dorsolateral prefrontal cortex (DLPFC) plays a key role in working memory. Evidence indicates that transcranial magnetic stimulation (TMS) over the DLPFC can interfere with working memory performance. Here we investigated for how long continuous theta-burst stimulation (cTBS) over the DLPFC decreases working memory performance and whether the effect of cTBS on performance depends on working memory load. Forty healthy young subjects received either cTBS over the left DLPFC or sham stimulation before performing a 2-, and 3-back working memory letter task. An additional 0-back condition served as a non-memory-related control, measuring general attention. cTBS over the left DLPFC significantly impaired 2-back working memory performance for about 15 min, whereas 3-back and 0-back performances were not significantly affected. Our results indicate that the effect of left DLPFC cTBS on working memory performance lasts for roughly 15 min and depends on working memory load.

    Full Text Available O objetivo do artigo é efetuar a crítica de alguns ideários que cercam as noções de gerir e de trabalhar, bem como evidenciar a amplitude e a complexidade dos aspectos que envolvem o trabalho humano. Trata-se de uma elaboração de natureza teórica e que se vale de estudos no campo da educação, mas, também, de estudos desenvolvidos no campo da sociologia do trabalho, da psicologia do trabalho e da ergonomia. As conclusões apontam que uma racionalidade redutora das complexidades presentes nas situações de trabalho comumente se apresenta nas ações da gestão, comprometendo a finalidade social das instituições e repercutindo sobre os trabalhadores e trabalhadoras.This paper criticizes some ideas surrounding the notions of managing and working, ands pinpoints the broadness and complexity of the aspects involving human work. It is a theoretical elaboration that relies on studies in the fields of education, sociology of work, work psychology and ergonomics. Its conclusions suggest that the reductive rationality of the complexities present in work situations is also commonly at work in the actions of management, compromising the social purpose of the institutions and having an impact on its employers.

    Full Text Available Optimal repair and adaptation of skeletal muscle is facilitated by resident stem cells (satellite cells. To understand how different exercise modes influence satellite cell dynamics, we measured satellite cell activity in conjunction with markers of muscle damage and inflammation in human skeletal muscle following a single work- and intensity-matched bout of eccentric (ECC or concentric contractions (CON. Participants completed a single bout of ECC (n=7 or CON (n=7 of the knee extensors. A muscle biopsy was obtained before and 24 h after exercise. Functional measures and immunohistochemical analyses were used to determine the extent of muscle damage and indices of satellite cell activity. Cytokine concentrations were measured using a multiplexed magnetic bead assay. Isokinetic peak torque decreased following ECC (p<0.05 but not CON. Greater histological staining of the damage marker Xin was observed in muscle samples of ECC vs CON. Tenasin C immunoreactivity increased 15 fold (P<0.01 following ECC and was unchanged following CON. The inflammatory cytokines interferon gamma-induced protein 10 (IP-10 and monocyte chemotactic protein 1 (MCP-1 increased pre- to post-ECC (4.26 ± 1.4 vs. 10.49 ± 5.8 pg/ml, and 3.06 ± 0.7 vs. 6.25 ± 4.6 pg/ml, respectively; p<0.05. There was no change in any cytokine post-CON. Satellite cell content increased 27% pre- to post-ECC (0.10 ± 0.031 vs. 0.127 ± 0.041, respectively; p<0.05. There was no change in satellite cell number in CON (0.099 ± 0.027 vs. 0.102 ± 0.029, respectively. There was no fiber type-specific satellite cell response following either exercise mode. ECC but not CON resulted in an increase in MyoD positive nuclei per myofiber pre- to post-exercise (p<0.05, but there was no change in MyoD DNA binding activity in either condition. In conclusion, ECC but not CON results in functional and histological evidence of muscle damage that is accompanied by increased satellite cell activity 24 h post-exercise.

  17. Six degree-of-freedom analysis of hip, knee, ankle and foot provides updated understanding of biomechanical work during human walking.

    2015-03-01

    Measuring biomechanical work performed by humans and other animals is critical for understanding muscle-tendon function, joint-specific contributions and energy-saving mechanisms during locomotion. Inverse dynamics is often employed to estimate joint-level contributions, and deformable body estimates can be used to study work performed by the foot. We recently discovered that these commonly used experimental estimates fail to explain whole-body energy changes observed during human walking. By re-analyzing previously published data, we found that about 25% (8 J) of total positive energy changes of/about the body's center-of-mass and >30% of the energy changes during the Push-off phase of walking were not explained by conventional joint- and segment-level work estimates, exposing a gap in our fundamental understanding of work production during gait. Here, we present a novel Energy-Accounting analysis that integrates various empirical measures of work and energy to elucidate the source of unexplained biomechanical work. We discovered that by extending conventional 3 degree-of-freedom (DOF) inverse dynamics (estimating rotational work about joints) to 6DOF (rotational and translational) analysis of the hip, knee, ankle and foot, we could fully explain the missing positive work. This revealed that Push-off work performed about the hip may be >50% greater than conventionally estimated (9.3 versus 6.0 J, P=0.0002, at 1.4 m s(-1)). Our findings demonstrate that 6DOF analysis (of hip-knee-ankle-foot) better captures energy changes of the body than more conventional 3DOF estimates. These findings refine our fundamental understanding of how work is distributed within the body, which has implications for assistive technology, biomechanical simulations and potentially clinical treatment.

    The dorsolateral prefrontal cortex (DLPFC) plays a key role in working memory. Evidence indicates that transcranial magnetic stimulation (TMS) over the DLPFC can interfere with working memory performance. Here we investigated for how long continuous theta-burst stimulation (cTBS) over the DLPFC decreases working memory performance and whether the effect of cTBS on performance depends on working memory load. Forty healthy young subjects received either cTBS over the left DLPFC or sham stimulation before performing a 2-, and 3-back working memory letter task. An additional 0-back condition served as a non-memory-related control, measuring general attention. cTBS over the left DLPFC significantly impaired 2-back working memory performance for about 15 min, whereas 3-back and 0-back performances were not significantly affected. Our results indicate that the effect of left DLPFC cTBS on working memory performance lasts for roughly 15 min and depends on working memory load. PMID:25781012

    Wilson, Rebecca D; Klein, James D; Hagler, Debra

    2014-01-01

    The purpose of this study was to determine whether a difference exists in learner performance and the type and frequency of diagnostic reasoning skills used, based on the method of case presentation. Faculty can select from a variety of methods for presenting cases when teaching diagnostic reasoning, but little evidence exists with regard to how students use these skills while interacting with the cases. A total of 54 nursing students participated in two case analyses using human patient and computer-based simulations. Participant performance and diagnostic reasoning skills were analyzed. Performance was significantly better with the human patient simulation case. All diagnostic reasoning skills were used during both methods of case presentation, with greater performance variation in the computer-based simulation. Both human patient and computer-based simulations are beneficial for practicing diagnostic reasoning skills; however, these findings support the use of human patient simulations for improving student performance in case synthesis.

    2017-06-01

    In November 2010 the United Nations General Assembly set up a working group to strengthen the protection of human rights for older persons (UN Open-ended Working Group on Ageing) with the United Nations Resolution A/C.3/65/L.8/Rev.1. In December 2016 the members of the working group met for the seventh time and discussed how they can approach the fulfillment of the mandate. In addition to better implementation, the strengthening of rights can consist of closing existing gaps or further differentiation of the rights in order to give the member states better guidance on how to implement them. To improve the human rights of older persons a task of the members of the working group would be to examine the existing rights and, where possible, adjust them to the real needs of the group. One of the major challenges facing the working group is already apparent: who belongs to the group of older persons and how could the group be described? This article deals with the presentation of the international process, new developments at the regional level and the attitudes of the member states and the civil society. A further aim is to present the possibilities and effects of a comprehensive legally binding instrument.

  6. Non-reductive continental naturalism in the contemporary humanities: Working with Hélène Metzger's philosophical reflections.

    Van der Tuin, Iris

    2013-04-01

    This article engages with the philosophical reflections of the French historian of science Hélène Metzger (1886-1944) in order to develop a vocabulary for understanding the rise of non-reductive Continental naturalism in the contemporary humanities. The bibliography of current naturalist approaches in the arts and the human sciences is still in the making, but it is altogether clear that the trend is not scientist or historicist or relativist. This epistemological diagnosis refers us to Metzger, who found herself surrounded with the logical positivism of the Wiener Kreis, on the one hand, and the historicism of her French colleagues, on the other, as well as with the infiltration of the history of science by a chronological empiricism. In this article I will take the most recent book of Vicki Kirby - Quantum Anthropologies: Life at Large from 2011 - as an exemplary case of non-reductive Continental naturalist scholarship in the humanities today and by reading it through the concepts of Metzger, I will demonstrate how this type of research leads to refreshing insights in what constitutes positive humanities knowledge and what is the role of the a priori in the field.

    A communication strategy was developed by The Consortium to Perform Human Biomonitoring on a European Scale (COPHES), as part of its objectives to develop a framework and protocols to enable the collection of comparable human biomonitoring data throughout Europe. The framework and protocols were tested in the pilot study DEMOCOPHES (Demonstration of a study to Coordinate and Perform Human biomonitoring on a European Scale). The aims of the communication strategy were to raise awareness of human biomonitoring, encourage participation in the study and to communicate the study results and their public health significance. It identified the audiences and key messages, documented the procedure for dissemination of results and was updated as the project progressed. A communication plan listed the tools and materials such as press releases, flyers, recruitment letters and information leaflets required for each audience with a time frame for releasing them. Public insight research was used to evaluate the recruitment material, and the feedback was used to improve the documents. Dissemination of results was coordinated in a step by step approach by the participating countries within DEMOCOPHES, taking into account specific national messages according to the needs of each country. Participants received individual results, unless they refused to be informed, along with guidance on what the results meant. The aggregate results and policy recommendations were then communicated to the general public and stakeholders, followed by dissemination at European level. Several lessons were learnt that may assist other future human biomonitoring studies. Recruitment took longer than anticipated and so social scientists, to help with community engagement, should be part of the research team from the start. As a European study, involving multiple countries, additional considerations were needed for the numerous organisations, different languages, cultures, policies and priorities

  14. Research Approaches and Methods for Evaluating the Protein Quality of Human Foods Proposed by an FAO Expert Working Group in 2014.

    The Protein Digestibility Corrected Amino Acid Score (PDCAAS) has been adopted for assessing protein quality in human foods since 1991, and the shortcomings of using the PDCAAS have been recognized since its adoption. The 2011 FAO Expert Consultation recognized that the Digestible Indispensable Amino Acid Score (DIAAS) was superior to the PDCAAS for determining protein quality. However, there were insufficient human data on amino acid digestibility before adopting the DIAAS. More human data were needed before DIAAS could be implemented. In 2014, FAO convened an expert working group to propose and agree on research protocols using both human-based assays and animal models to study ileal amino acid digestibility (metabolic availability) of human foods. The working group identified 5 research protocols for further research and development. A robust database of protein digestibility of foods commonly consumed worldwide, including those consumed in low-income countries, is needed for an informed decision on adopting the DIAAS. A review on the impacts of using the DIAAS on public health policies is necessary. It would be advantageous to have a global coordinating effort to advance research and data collection. Collaboration with international and national agriculture institutes is desirable. Opportunities should be provided for young researchers, particularly those from developing countries, to engage in protein-quality research for sustainable implementation of DIAAS. To conclude, the DIAAS is a conceptually preferable method compared with the PDCAAS for protein and amino acid quality evaluation. However, the complete value of the DIAAS and its impact on public health nutrition cannot be realized until there are sufficient accumulated ileal amino acid digestibility data on human foods that are consumed in different nutritional and environmental conditions, measured by competent authorities. A future meeting may be needed to evaluate the size and quality of the data set

    2012-01-01

    This article examines the occupational health considerations that might impact the health and wellbeing of public health workers during responses to natural (eg, floods and hurricanes) and human-caused (eg, terrorism, war, and shootings) disasters. There are a number of articles in the medical literature that argue the impact of how working long hours by house staff physicians, nurses, and first-responders may pose health and safety concerns regarding the patients being treated. The question examined here is how working long hours may pose health and/or safety concerns for the public health workers themselves, as well as to those in the communities they serve. The health problems related to sleep deprivation are reviewed. Current policies and legislations regarding work-hour limitations are examined. Policy implications are discussed.

  16. Spatial working memory in immersive virtual reality foraging: path organization, traveling distance and search efficiency in humans (Homo sapiens).

    De Lillo, Carlo; Kirby, Melissa; James, Frances C

    2014-05-01

    Search and serial recall tasks were used in the present study to characterize the factors affecting the ability of humans to keep track of a set of spatial locations while traveling in an immersive virtual reality foraging environment. The first experiment required the exhaustive exploration of a set of locations following a procedure previously used with other primate and non-primate species to assess their sensitivity to the geometric arrangement of foraging sites. The second experiment assessed the dependency of search performance on search organization by requiring the participants to recall specific trajectories throughout the foraging space. In the third experiment, the distance between the foraging sites was manipulated in order to contrast the effects of organization and traveling distance on recall accuracy. The results show that humans benefit from the use of organized search patterns when attempting to monitor their travel though either a clustered "patchy" space or a matrix of locations. Their ability to recall a series of locations is dependent on whether the order in which they are explored conformed or did not conform to specific organization principles. Moreover, the relationship between search efficiency and search organization is not confounded by effects of traveling distance. These results indicate that in humans, organizational factors may play a large role in their ability to forage efficiently. The extent to which such dependency may pertain to other primates and could be accounted for by visual organization processes is discussed on the basis of previous studies focused on perceptual grouping, search, and serial recall in non-human species.

    A nitric oxide synthase (NOS)-like activity has been demonstrated in human red blood cells (RBCs), but doubts about its functional significance, isoform identity and disease relevance remain. Using flow cytometry in combination with the nitric oxide (NO)-imaging probe DAF-FM we find that all blood cells form NO intracellularly, with a rank order of monocytes > neutrophils > lymphocytes > RBCs > platelets. The observation of a NO-related fluorescence within RBCs was unexpected given the abundance of the NO-scavenger oxyhemoglobin. Constitutive normoxic NO formation was abolished by NOS inhibition and intracellular NO scavenging, confirmed by laser-scanning microscopy and unequivocally validated by detection of the DAF-FM reaction product with NO using HPLC and LC-MS/MS. Using immunoprecipitation, ESI-MS/MS-based peptide sequencing and enzymatic assay we further demonstrate that human RBCs contain an endothelial NOS (eNOS) that converts L-(3)H-arginine to L-(3)H-citrulline in a Ca(2+)/calmodulin-dependent fashion. Moreover, in patients with coronary artery disease, red cell eNOS expression and activity are both lower than in age-matched healthy individuals and correlate with the degree of endothelial dysfunction. Thus, human RBCs constitutively produce NO under normoxic conditions via an active eNOS isoform, the activity of which is compromised in patients with coronary artery disease.

    Healthcare practitioners, patient safety leaders, educators and researchers increasingly recognise the value of human factors/ergonomics and make use of the discipline's person-centred models of sociotechnical systems. This paper first reviews one of the most widely used healthcare human factors systems models, the Systems Engineering Initiative for Patient Safety (SEIPS) model, and then introduces an extended model, 'SEIPS 2.0'. SEIPS 2.0 incorporates three novel concepts into the original model: configuration, engagement and adaptation. The concept of configuration highlights the dynamic, hierarchical and interactive properties of sociotechnical systems, making it possible to depict how health-related performance is shaped at 'a moment in time'. Engagement conveys that various individuals and teams can perform health-related activities separately and collaboratively. Engaged individuals often include patients, family caregivers and other non-professionals. Adaptation is introduced as a feedback mechanism that explains how dynamic systems evolve in planned and unplanned ways. Key implications and future directions for human factors research in healthcare are discussed.

    Madsen et al (1) recently published a secondary analysis on data provided by the Project on Burnout, Motivation and Job Satisfaction (PUMA). The aim of their study, published in the Scandinavian Journal of Work, Environment & Health was to examine the associations between unnecessary work tasks and a decreased level of mental health. Though the topic was quite novel, reading this work proved disturbing and raised issues. Based on the results of this study, the authors stated that there is an association between unnecessary work tasks (assessed by a single question) and a decreased level of mental health, idem [assessed by the Mental Health Inventory (MHI-5)], in the specific population included in this PUMA survey. The authors point out a limitation of the study, namely that unnecessary work tasks were evaluated using one single question: "Do you sometimes have to do things in your job which appear to be unnecessary?". Semmer defines unnecessary work task as "tasks that should not be carried out at all because they do not make sense or because they could have been avoided, or could be carried out with less effort if things were organized more efficiently" (2). De facto, qualifying what an unnecessary task is requires stating or explaining whether the task makes sense. Making sense or not is not an objective notion. It is very difficult for either a manager or an employee to say if a task is necessary or not. Most important is that it makes sense from the worker's point of view. Making sense and being necessary are not synonyms. Some tasks do not make sense but are economically necessary (eg, when, as physicians, we are reporting our activity using ICD-10 on computers instead of being at patients' bedsides or reading this journal). Thus, there is a wide gap between Semmer's definition and the question used by the authors to evaluate his concept. A secondary analysis based on a single question is not adequate to evaluate unnecessary tasks. Nowadays, the general trend

    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

    Single strand breaks of DNA of peripheral mononuclear blood cells from 97 male and female workers occupationally exposed to ethylene oxide were analysed by the alkaline elution method. These individuals were occupied with the sterilization of medical devices in hospitals and in commercial plants. Ethylene oxide in the air of the working areas was detected up to a maximal concentration of 16.5 mg/m3 calculated as 4-h time-weighted average (4h TWA). Mean value was 1.47 +/- 0.52 mg/m3 (1 mg/m3 = 0.55 ppm). Compared to the mean elution rate of the DNA from non-smoking workers exposed to air concentrations of ethylene oxide below the detection limit of 0.1 mg/m3 (4h TWA) the non-smokers working in rooms with a concentration of ethylene oxide between 0.5 mg/m3 and 2 mg/m3 showed a statistically significant (P ethylene oxide a statistically significant (P ethylene oxide the non-smoking workers could be classified into two subpopulations. In the majority of the non-smokers (67%) approximately 5-fold more DNA strand breaks were induced by ethylene oxide than in the other non-smokers. A lowest detectable effect level could only be specified for non-smokers. (ABSTRACT TRUNCATED AT 250 WORDS)

    Maintenance of a body weight 10% above or below that "customary" for lean or obese individuals results in respective increases or decreases in the energy expended in low levels of physical activity (nonresting energy expenditure, NREE). These changes are greater than can be accounted for by the altered body weight or composition and are due mainly to altered skeletal muscle work efficiency at low levels of power generation. We performed biochemical analysis of vastus lateralis muscle needle biopsy samples to determine whether maintenance of an altered body weight was associated with changes in skeletal muscle histomorphology. We found that the maintenance of a 10% reduced body weight was associated with significant declines in glycolytic (phosphofructokinase, PFK) enzyme activity and, in particular, in the ratio of glycolytic to oxidative (cytochrome c oxidase, COX) enzyme activity without significant changes in the activities of enzymes relevant to mitochondrial density, respiratory chain activity, or fuel transport; or in skeletal muscle fiber type or glycogen stores. The fractional change in the ratio of PFK/COX activity in subjects following weight loss was significantly correlated with changes in the systemic respiratory exchange ratio (RER) and measures of mechanical efficiency of skeletal muscle at low workloads (pedaling a bicycle to generate 10 or 25 W of power). Thus, predictable changes in systemic skeletal muscle biochemistry accompany the maintenance of an altered body weight and account for a significant portion of the variance in skeletal muscle work efficiency and fuel utilization at reduced body weight.

    The purpose of this study was to clarify the characteristic of workloads on human care worker with the introduction of IT system, and suggested the support measures for KAIZEN in Japan. The investigation method is workflow line and hearing with a focus on work observation. The objects were 8 human care workers of the acute hospital that introduced an electronic system. By the introduction of the electronic chart, the nurse station sojourn time decreased, sickroom sojourn time increased, and time about direct nursing care to a patient increased. In addition, access to patient information became easy, and the offer of the health care service based on correct information came to be possible in real time. By The point of workflow line, it was effect that moving lengths decreased in order to install the electronic chart in patients' rooms. Though, it was a problem that it hasn't formed where to place the instruments such as sphygmomanometer, clinical thermometer and others.

    This study assesses the importance of customer-contact intensity at the service encounter level as a determinant of service quality assessments. Using data from the U.S. Department of Veterans Affairs, it shows that performance-driven human resources practices play an important role as determinants of employee customer orientation and service capability in both high-contact (outpatient healthcare) and low-contact (benefits claim processing) human service contexts. However, there existed significant differences across service delivery settings in the salience of customer orientation and the congruence between employee and customer perceptions of service quality, depending on the intensity of customer contact. In both contexts, managerial attention to high-performance work systems and customer-orientation has the potential to favorably impact perceptions of service quality, amplify consumer satisfaction, and enhance operational efficiency.

The psychophysiological support of operator consisted in combined presentation of functional music, surf noise and pulsed dynamic green lighting under a special program built-up on the principle of biological feedback of heart and respiration rates. The individually adaptable audio and visual pulses on the programme showed a rather high efficiency as was confirmed by the change in the set of psychophysiological indices (heart rate, arterial pressure, cutaneogalvanic reaction, accommodation volume, critical rate of flicker fusion, electroencephalogram), and subjective SAM (self-feeling, activity, mood) estimates in the course of extended operator's activity.

    Simulation of humanoid adaptive behaviors is a prerequisite of ergonomic evaluation. To overcome the shortages of existing technologies, an autonomic optimization model of virtual human's working behaviors is presented based on multi-agent cooperative games. In this model, the humanoid adaptive behaviors in working environment is defined as multi-objective optimization problem, and the definitions of mannequin workspace and behavior elements are proposed for discretization of human behaviors. A simulation algorithm based on fuzzy multi-objective games theory is presented to solve this model. With fuzzy multi-objective Nash negotiation theory, a grads-up method is adopted to search the Pareto optimizing solutions of human's working posture. Case studies show that the human's comfortable working posture can be derived by the new strategy even in cases with only insufficient data and better adaptability of the method in engineering domain can be reached.%人体自适应行为仿真是实现人机工程学评估的前提条件.针对已有技术存在的不足,提出了一种基于多Agent合作式博弈的虚拟人作业行为自主优化模型.该模型将工作环境中人体自适应行为定义为一个多目标优化问题,提出了人体工作状态空间和人体行为元素的概念,以实现人体行为的离散化设计了人体行为仿真算法以求解上述模型.算法采用梯度上升的策略来搜索满足模糊多目标Nash谈判条件的人体作业姿态的Pareto最优解.仿真实验表明,该方法可以在缺少相关数据的情况下推导出舒适的人体工作姿态,在工程领域中表现出较好的适用性.

    The transition from the current air traffic system to the next generation air traffic system will require the introduction of new automated systems, including transferring some functions from air traffic controllers to on­-board automation. This report describes a new design verification and validation (V&V) methodology for assessing aviation safety. The approach involves a detailed computer simulation of work practices that includes people interacting with flight-critical systems. The research is part of an effort to develop new modeling and verification methodologies that can assess the safety of flight-critical systems, system configurations, and operational concepts. The 2002 Ueberlingen mid-air collision was chosen for analysis and modeling because one of the main causes of the accident was one crew's response to a conflict between the instructions of the air traffic controller and the instructions of TCAS, an automated Traffic Alert and Collision Avoidance System on-board warning system. It thus furnishes an example of the problem of authority versus autonomy. It provides a starting point for exploring authority/autonomy conflict in the larger system of organization, tools, and practices in which the participants' moment-by-moment actions take place. We have developed a general air traffic system model (not a specific simulation of Überlingen events), called the Brahms Generalized Ueberlingen Model (Brahms-GUeM). Brahms is a multi-agent simulation system that models people, tools, facilities/vehicles, and geography to simulate the current air transportation system as a collection of distributed, interactive subsystems (e.g., airports, air-traffic control towers and personnel, aircraft, automated flight systems and air-traffic tools, instruments, crew). Brahms-GUeM can be configured in different ways, called scenarios, such that anomalous events that contributed to the Überlingen accident can be modeled as functioning according to requirements or in an

    Substance use disorders (SUDs) can be viewed as a pathology of neuroadaptation. The pharmacological overstimulation of neural mechanisms of reward, motivated learning and memory leads to drug-seeking behavior. A critical characteristic of SUDs is the appearance of craving, the motivated desire and urge to use, which is a main focus of current pharmacological and behavioral therapies. Recent proof-of-concept studies have tested the effects of non-invasive brain stimulation on craving. Although its mechanisms of action are not fully understood, this approach shows interesting potential in tuning down craving and possibly consumption of diverse substances. This article reviews available results on the use of repetitive transcranial magnetic stimulation (rTMS) and transcranial electrical stimulation (tES) in SUDs, specifically tobacco, alcohol and psychostimulant use disorders. We discuss several important factors that need to be addressed in future works to improve clinical assessment and effects of non-invasive brain stimulation in SUDs. Factors discussed include brain stimulation devices and parameters, study designs, brain states and subjects’ characteristics. PMID:26449761

    The acute promyelocytic leukemia (APL) subtype of acute myeloid leukemia (AML) is characterized by chromosomal translocations that result in fusion proteins, including the promyelocytic leukemia-retinoic acid receptor, alpha fusion protein (PML-RARα). All-trans retinoic acid (atRA) treatment is the standard drug treatment for APL yielding cure rates > 80% by activating transcription and proteasomal degradation of retinoic acid receptor, alpha (RARα). Whereas combination therapy with As2O3 has increased survival further, patients that experience relapse and are refractory to atRA and/or As2O3 is a clinically significant problem. BCL-2 family proteins regulate apoptosis and over-expression of anti-apoptotic B-cell leukemia/lymphoma 2 (BCL-2) family proteins has been associated with chemotherapeutic resistance in APL including impairment of the ability of atRA to induce growth arrest and differentiation. Here we investigated the novel BH3 domain mimetic, JY-1-106, which antagonizes the anti-apoptotic BCL-2 family members B-cell lymphoma-extra large (BCL-xL) and myeloid cell leukemia-1 (MCL-1) alone and in combination with retinoids including atRA, AM580 (RARα agonist), and SR11253 (RARγ antagonist). JY-1-106 reduced cell viability in HL-60 cells alone and in combination with retinoids. The combination of JY-1-106 and SR11253 had the greatest impact on cell viability by stimulating apoptosis. These studies indicate that dual BCL-xL/MCL-1 inhibitors and retinoids could work cooperatively in leukemia treatment.

    Full Text Available The monitoring mechanism of the Council of Europe Convention on Action against Trafficking in Human Beings (CoE Convention consists of an independent group of experts (GRETA and a Committee of Parties. GRETA, which began work in 2009, develops questionnaires for States Parties, reviews their replies and conducts study visits. It then produces a report that is used by the Committee of Parties to make recommendations. This article analyses GRETA’s work until November 2011 by assessing the available materials including the questionnaire, the three published replies of States Parties to the questionnaire and the five published final reports on the parties. The objective of the article is to examine the capacity of this process to contribute to enhancing the accountability of States Parties, and to consider whether the application of a human rights-based approach by the parties can, in fact, be effectively monitored. The article also considers the role of civil society in the monitoring process and the ways in which this could be enhanced.

    Nursing workload is increasingly thought to contribute to both nurses' quality of working life and quality/safety of care. Prior studies lack a coherent model for conceptualising and measuring the effects of workload in healthcare. In contrast, we conceptualised a human factors model for workload specifying workload at three distinct levels of analysis and having multiple nurse and patient outcomes. To test this model, we analysed results from a cross-sectional survey of a volunteer sample of nurses in six units of two academic tertiary care paediatric hospitals. Workload measures were generally correlated with outcomes of interest. A multivariate structural model revealed that: the unit-level measure of staffing adequacy was significantly related to job dissatisfaction (path loading=0.31) and burnout (path loading=0.45); the task-level measure of mental workload related to interruptions, divided attention, and being rushed was associated with burnout (path loading=0.25) and medication error likelihood (path loading=1.04). Job-level workload was not uniquely and significantly associated with any outcomes. The human factors engineering model of nursing workload was supported by data from two paediatric hospitals. The findings provided a novel insight into specific ways that different types of workload could affect nurse and patient outcomes. These findings suggest further research and yield a number of human factors design suggestions.

    Duplication of human chromosome 22q11.2 is associated with elevated rates of mental retardation, autism and many other behavioral phenotypes. However, because duplications cover 1.5-6 Mb, the precise manner in which segments of 22q11.2 causally affect behavior is not known in humans. We have now determined the developmental impact of over-expression of an approximately 190 kb segment of human 22q11.2, which includes the genes TXNRD2, COMT and ARVCF, on behaviors in bacterial artificial chromosome (BAC) transgenic (TG) mice. BAC TG mice and wild-type (WT) mice were tested for their cognitive capacities, affect- and stress-related behaviors and motor activity at 1 and 2 months of age. An enzymatic assay determined the impact of BAC over-expression on the activity level of COMT. BAC TG mice approached a rewarded goal faster (i.e. incentive learning), but were impaired in delayed rewarded alternation during development. In contrast, BAC TG and WT mice were indistinguishable in rewarded alternation without delays, spontaneous alternation, prepulse inhibition, social interaction, anxiety-, stress- and fear-related behaviors and motor activity. Compared with WT mice, BAC TG mice had an approximately 2-fold higher level of COMT activity in the prefrontal cortex, striatum and hippocampus. These data suggest that over-expression of this 22q11.2 segment enhances incentive learning and impairs the prolonged maintenance of working memory, but has no apparent effect on working memory per se, affect- and stress-related behaviors or motor capacity. High copy numbers of this 22q11.2 segment might contribute to a highly selective set of phenotypes in learning and cognition during development.

    and enterprise levels, in terms of organisational/social/technological environment. This is particularly noted for the organisational environment. The compatibility values obtained for the experienced domains mirror those obtained for acting domains. The overall workload was assessed as requiring major redesign during the day shift and needing added responsibilities for the night shift according to both expert and qualified workers. The assessment of qualified workers is comparable with that of expert workers for the job content and immediate surroundings. Differences are more observed for process- and enterprise-based factors; thereby, providing company management different perspectives in order to devise organisational strategies conducive for optimum human and corporate health and pointing to the probable interactions of the different systems impacting individual and enterprise performance. STATEMENT OF RELEVANCE: This research examines similarities and differences between qualified and expert workers in their assessment of the worker-work environment interface. The contribution to improved understanding of the complex interactions of human-at-work and enterprise systems should be beneficial to organisations in their quest to remain competitive in a global economy.

    The Biopharmaceutics Classification System (BCS) allows compounds to be classified based on their in vitro solubility and intestinal permeability. The BCS has found widespread use in the pharmaceutical community to be an enabling guide for the rational selection of compounds, formulation for clinical advancement, and generic biowaivers. The Pediatric Biopharmaceutics Classification System (PBCS) Working Group was convened to consider the possibility of developing an analogous pediatric-based classification system. Because there are distinct developmental differences that can alter intestinal contents, volumes, permeability, and potentially biorelevant solubilities at different ages, the PBCS Working Group focused on identifying age-specific issues that need to be considered in establishing a flexible, yet rigorous PBCS. We summarized the findings of the PBCS Working Group and provided insights into considerations required for the development of a PBCS. Through several meetings conducted both at The Eunice Kennedy Shriver National Institute of Child Health, Human Development-US Pediatric Formulation Initiative Workshop (November 2011) and via teleconferences, the PBCS Working Group considered several high-level questions that were raised to frame the classification system. In addition, the PBCS Working Group identified a number of knowledge gaps that need to be addressed to develop a rigorous PBCS. It was determined that for a PBCS to be truly meaningful, it needs to be broken down into several different age groups that account for developmental changes in intestinal permeability, luminal contents, and gastrointestinal (GI) transit. Several critical knowledge gaps were identified, including (1) a lack of fully understanding the ontogeny of drug metabolizing enzymes and transporters along the GI tract, in the liver, and in the kidney; (2) an incomplete understanding of age-based changes in the GI, liver, and kidney physiology; (3) a clear need to better understand

    Altered myocardial fuel selection likely underlies cardiac disease risk in diabetes, affecting oxygen demand and myocardial metabolic flexibility. We investigated myocardial fuel selection and metabolic flexibility in human type 2 diabetes mellitus (T2DM), using positron emission tomography to measure rates of myocardial fatty acid oxidation {16-[(18)F]fluoro-4-thia-palmitate (FTP)} and myocardial perfusion and total oxidation ([(11)C]acetate). Participants underwent paired studies under fasting conditions, comparing 3-h insulin + glucose euglycemic clamp conditions (120 mU·m(-2)·min(-1)) to 3-h saline infusion. Lean controls (n = 10) were compared with glycemically controlled volunteers with T2DM (n = 8). Insulin augmented heart rate, blood pressure, and stroke index in both groups (all P efficiency was lower in T2DM (P = 0.006) and decreased in both groups with the insulin-induced increase in work and shift in fuel utilization (P = 0.01). Augmented fatty acid oxidation is present under baseline and insulin-treated conditions in T2DM, with impaired insulin-induced shifts away from fatty acid oxidation. This is accompanied by reduced work efficiency, possibly due to greater oxygen consumption with fatty acid metabolism. These observations suggest that improved fatty acid suppression, or reductions in myocardial fatty acid uptake and retention, could be therapeutic targets to improve myocardial ischemia tolerance in T2DM.

    HLA-NET (a European COST Action) aims at networking researchers working in bone marrow transplantation, epidemiology and population genetics to improve the molecular characterization of the HLA genetic diversity of human populations, with an expected strong impact on both public health and fundamental research. Such improvements involve finding consensual strategies to characterize human populations and samples and report HLA molecular typings and ambiguities; proposing user-friendly access to databases and computer tools and defining minimal requirements related to ethical aspects. The overall outcome is the provision of population genetic characterizations and comparisons in a standard way by all interested laboratories. This article reports the recommendations of four working groups (WG1-4) of the HLA-NET network at the mid-term of its activities. WG1 (Population definitions and sampling strategies for population genetics’ analyses) recommends avoiding outdated racial classifications and population names (e.g. ‘Caucasian’) and using instead geographic and/or cultural (e.g. linguistic) criteria to describe human populations (e.g. ‘pan-European’). A standard ‘HLA-NET POPULATION DATA QUESTIONNAIRE’ has been finalized and is available for the whole HLA community. WG2 (HLA typing standards for population genetics analyses) recommends retaining maximal information when reporting HLA typing results. Rather than using the National Marrow Donor Program coding system, all ambiguities should be provided by listing all allele pairs required to explain each genotype, according to the formats proposed in ‘HLA-NET GUIDELINES FOR REPORTING HLA TYPINGS’. The group also suggests taking into account a preliminary list of alleles defined by polymorphisms outside the peptide-binding sites that may affect population genetic statistics because of significant frequencies. WG3 (Bioinformatic strategies for HLA population data storage and analysis) recommends the use of

    Full Text Available Purpose: This paper aims to analyze the situation of job satisfaction and organizational commitment in the hospitality sector in Cordoba (Spain, trying to analyze the possible influence or relationship between contractual typology and time dedication to both constructs. Design/methodology/approach: Initial theoretical study of constructs and certain independent variables, design of a field work, approach of a number of assumptions associated with the study variables and application of statistical techniques, which lead, finally, to the main results and conclusions emanating from them. Findings and Originality/value: Contributions and Results: workers under permanent employment relationships have a higher level of organizational commitment, but not in the case of job satisfaction given its cyclical more than global character. Meanwhile, when the employees have a time part-time dedication their commitment is higher, as it allows a better reconciliation of work and family life. Research limitations/implications: To progress in research on these constructs it would be desirable to develop official statistical sources, allowing results which lead to the establishment of labour policies aimed at improving the welfare of workers. Practical implications: Among other programs, systems strategic compensation and performance evaluation can be better focused through knowledge of how the contractual relationships and time commitment of persons to whom they are addressed, influence the satisfaction and commitment of these. Originality/value: The better understanding of the relationships in the field of study of this article, allows hotel managers to adopt measures that encourage satisfaction and commitment of its human resources, through the pursuit of stable labour relations that allow reconciliation of family and working life.

    Full Text Available Successful implementation of any broad-scale immigrant legalization program requires an adequately funded infrastructure of immigrant-serving organizations. In 2014, President Obama announced an expanded Deferred Action for Childhood Arrivals (DACA program, as well as the Deferred Action for Parents of Citizens and Lawful Permanent Residents (DAPA program, which would make it possible for approximately five million people to attain lawful, albeit temporary, status and employment authorization. As the initial DACA program instituted in 2012 has already stretched the capacity of immigrant-serving organizations to their limits or even beyond them, the possibility of full implementation of DAPA and the expanded DACA programs presents a formidable challenge for these organizations.In this paper, the Human Resources Working Group of the Committee for Immigration Reform Implementation (CIRI draws on the lessons of the Immigrant Reform and Control Act of 1986 (IRCA, DACA, and other initiatives to provide a roadmap for immigrant service delivery agencies and their partners in planning for implementation of the expanded DACA and the DAPA programs, with an eye (ultimately to broad legislative reform. In particular, this paper focuses on the funding and human resources that the immigrant service delivery field, writ large, would require to implement these programs.If expanded DACA and DAPA were implemented, the CIRI Working Group estimates that, of the total of five million that may be eligible, 1.08 million individuals will require extensive application assistance, generating the need for approximately three times more full-time staff than are currently in the field. Moreover, without additional funding and staff, agencies will likely not be able to shift a portion of staff time to accommodate any new program, even taking the typical fee-for-service model into account. Thus, the paper identifies a pressing need for “upfront” funding as early in the

    A load forecasting technique, based upon an autoregressive (AR) method is presented. Its use for short term load forecasting is assessed by direct comparison with real forecasts made by human operators of the Lerwick power station on the Shetland Islands. A substantial improvement in load prediction, as measured by a reduction of RMS error, is demonstrated. Shetland has a total installed capacity of about 68 MW, and an average load (1990) of around 20 MW. Although the operators could forecast the load for a few distinct hours better than the AR method, results from simulations of the scheduling and operation of the generating plant show that the AR forecasts provide increased overall system performance. A detailed model of the island power system, which includes plant scheduling, was run using the AR and Lerwick operators` forecasts as input to the scheduling routine. A reduction in plant cycling, underloading and fuel consumption was obtained using the AR forecasts rather than the operators` forecasts in simulations over a 28 day study period. It is concluded that the load forecasting method presented could be of benefit to the operators of such mesoscale power systems. (author)

    Full Text Available Acute stress has an important impact on higher-order cognitive functions supported by the prefrontal cortex (PFC such as working memory (WM. In rodents, such effects are mediated by stress-induced alterations in catecholaminergic signaling, but human data in support of this notion is lacking. A common variation in the gene encoding Catechol-O-methyltransferase (COMT is known to affect basal catecholaminergic availability and PFC functions. Here, we investigated whether this genetic variation (Val158Met modulates effects of stress on WM-related prefrontal activity in humans. In a counterbalanced crossover design, 41 healthy young men underwent functional Magnetic Resonance Imaging (fMRI while performing a numerical N-back WM task embedded in a stressful or neutral context. Moderate psychological stress was induced by a well-controlled procedure involving viewing strongly aversive (versus emotionally neutral movie material in combination with a self-referencing instruction. Acute stress resulted in genotype-dependent effects on WM performance and WM-related activation in the dorsolateral PFC, with a relatively negative impact of stress in COMT Met-homozygotes as opposed to a relatively positive effect in Val-carriers. A parallel interaction was found for WM-related deactivation in the anterior medial temporal lobe. Our findings suggest that individuals with higher baseline catecholaminergic availability (COMT Met-homozygotes appear to reach a supraoptimal state under moderate levels of stress. In contrast, individuals with lower baselines (Val-carriers may reach an optimal state. Thus, our data show that effects of acute stress on higher-order cognitive functions vary depending on catecholaminergic availability at baseline, and thereby corroborate animal models of catecholaminergic signaling that propose a non-linear relationship between catecholaminergic activity and prefrontal functions.

    The aim of this study was to assess the construct and predictive validity of a new instrument for self-rating of stress-related Exhaustion Disorder (s-ED). Public healthcare workers and social insurance officers, 85% females, were included (N = 2,683) in a longitudinal study. The s-ED instrument, based on clinical criteria for Exhaustion Disorder, was used at baseline to classify participants into three categories: non-s-ED, light/moderate s-ED and pronounced s-ED. Other assessments include burnout, anxiety, depression and work ability. Sick leave at follow-up after 2 years was defined as 14 days of ongoing sick leave (SA14) or a period of 60 days of sick leave during the last 12 months (SA60). Associations at baseline were expressed as prevalence ratios, and adjusted relative risks (RR) were calculated using Cox regression. At baseline, 16% reported s-ED. Scores of depression, anxiety and burnout and the rate of poor work ability increased with increasing severity of s-ED. Self-reported exhaustion at baseline increased the risk of reporting sickness absence at follow-up; pronounced s-ED RR 2.7; CI 1.8-4.0 for SA14 and RR 3.4; CI 2.3-5.2 for SA60. Self-rated ED corresponded well to established scales for mental health, indicating sufficient construct validity. Individuals reporting s-ED at baseline were more likely to report sickness absence at follow-up, confirming its predictive properties. The s-ED instrument may be a useful tool for occupational health services in identifying human service workers at risk of having or developing a potentially disabling stress-related mental illness.

    Full Text Available ABSTRACT: The long lasting opposition between qualitative and quantitative methods for studying behaviour has been overridden by interdisciplinary work in which methods can be combined to approach animal and human behaviour, thus contributing to drawing rigorous and useful conclusions. We show an example of this by combining a quasi-experimental design and descriptive methods to study working memory for the resolution of a spatial problem task (the Tower of Hanoi in a neuropsychiatric hospital inpatient with amnesia and executive deficits. Results from the quasi-experiment showed that the patient acquired strategies to solve the task with a high level of efficiency (F3/35 = 7, 19, p < .01. Qualitatively speaking, the patient developed more than one strategy to solve the problem, which indicates the presence of learning based on working memory. In the light of these findings, we discuss issues of mixed methods research and suggest the importance of developing mixed methods to study behaviour.

    Indoor and outdoor particulate matter (PM{sub 0.3-10}) number concentrations were established in two medieval churches in Cyprus. In both churches incense was burnt occasionally during Mass. The highest indoor PM{sub 0.5-1} concentrations compared with outdoors (10.7 times higher) were observed in the church that burning of candles indoors was allowed. Peak indoor black carbon concentration was 6.8 {mu}g m{sup -3} in the instances that incense was burning and 13.4 {mu}g m{sup -3} in the instances that the candles were burning (outdoor levels ranged between 0.6 and 1.3 {mu}g m{sup -3}). From the water soluble inorganic components determined in PM{sub 10}, calcium prevailed in all samples indoors or outdoors, whilst high potassium concentration indoors were a clear marker of combustion. Indoor sources of PM were clearly identified and their emission strengths were estimated via modeling of the results. Indoor estimated PM{sub 0.3-10} mass concentrations exceeded air quality standards for human health protection and for the preservation of works of art. - Particulate matter in medieval churches of Cyprus.

During those ten years while he was still studying, modem Chinese literature that had matured had an enormous impact on Fang Beifang. His novel masterpiece "The Storm Trilogy" revealed the Chinese (literary) experience in his work. Another novel masterpiece "The Malayan Trilogy" is an important work in which he reflected how the mentality of the Chinese in Singapore and Malaysia had shifted from an immigrant mindset to a recognition of themselves as locals. His technique of using a character to allude to history has laid an important foundation in Mabua realism literature. In his nearly seventy years of literary career, Fang Beifang, who steadfastly stood his ground and held on to his Malaysian identify, was concerned about all the problems in the growth of the Mahua community. He poured out his concerns for the communities in Singapore and Malaysia through his vibrant creativity with full passion. This humanism is an important literary spirit that he has left for the Mabua writing circle.

    A serological survey was performed using the enzyme-linked immunoelectrotransfer blot assay (EITB) in a village in the highlands of Peru where there are three distinct but close neighborhoods, to determine if there is a direct relationship between human and porcine Taenia solium infection. One hundred and eight out of 365 individuals were sampled, and 14 were seropositive (human seroprevalence 13%). Most seropositive individuals were neurologically asymptomatic. Thirty-eight out of 89 sampled pigs (43%) were seropositive. There was a clear geographical clustering of cases, and positive correlation between human and porcine seroprevalence found when comparing the three neighborhoods. Cysticercosis is an important cause of neurological morbidity in most developing countries, and control/eradication trials are now being increasingly applied. Porcine serology provides an appropriate indicator of T. solium environmental contamination and should be used to estimate the risk of infection when evaluating control measures.

Given the advancement of immunization of humans with increasing use of live-attenuated vaccines to prevent JE, there is increased interest to define quality standards for their manufacture, testing, nonclinical studies, and clinical studies to assess their efficacy and safety in humans. To this end, WHO convened a meeting with a group of international experts in February 2012 to develop guidelines for evaluating the quality, safety and efficacy of live-attenuated JE virus vaccines for prevention of human disease. This report summarizes collective views of the participants on scientific and technical issues that need to be considered in the guidelines. Copyright © 2013. Published by Elsevier Ltd..

  11. Work Stress

    OpenAIRE

    Roeters, Anne

    2014-01-01

    Most of us agree that stress is a growing problem within organizations. We hear about the postal workers who had killed fellow employees and supervisors, and then hear that a major cause of tension is at work. Friends tell us that they are stressed due to increased workload and he has to work overtime because the company is restructured. We read the polls that employees complain about the stress in trying to balance family life with the work. Stress is a dynamic condition in which an individu...

    The purpose of work-study program at the college is in essence to serve the students, which requires a philosophical reflection on the object, the people. Marx's Praxis-Human Theory emphasizes human existence in a way of generative thinking, which throws light on our work-study work. Generative-thinking oriented work-study mode takes the generation and integrity of human beings as the value guidance, while taking the generation of process and creation as the practice, highlighting the subjectivity, humanity, practicality, and openness; it focuses on the students democratic participation, multiple pursuits, accumulation of experience, and an integrated development.%高校勤工助学工作在本质上是一项对“人”的工作,这就需要对作为工作对象的“人”作出哲学省思。马克思“实践人学”理论以生成性思维视角强调人的实践性存在,对勤工助学工作具有现实启发意义。基于生成性思维方式的高校勤工助学工作模式以人的生成和完整为价值导向,以过程的生成和创造为实践诉求,凸显主体性、人文性、实践性和开放性,注重学生民主参与、多元追求、经验累积和整合发展。

    Bligaard, Lars-Ola; Andersson, Jonas; Thunberg, Anna; Osvalder, Anna-Lisa

    2008-01-15

    To stay competitive, the process industry of today faces increasing demands of continuous development for efficient use of both technical and human resources. An important step is to create new useful technical solutions, which also bring demands on functionality and usability. Functionality means that the new technology fulfils its purpose, while usability means that the human operator knows how to handle the new technology. If any of these two components are inferior, the potential of new technology will never be fully utilized. Today, a growing amount of advanced information technology is being used in supervisory control, at the same time as the process complexity is increasing. The technology has thereby become more difficult to understand, supervise and control, when processes, connections and logics are not visible in the same way as earlier. An increased level of automation together with reduced work force is also a contributing factor. Due to this, human-machine interaction (HMI) has become a more important aspect of quality in the development of new technology. From the operators' point of view, it is important that the development takes place with an increased transparency of the technical system, as well as reduction of the amount of information that has to be processed by the operator. To achieve a good human-machine interaction, it has to be considered during all phases in the development process of control room design. It is important that relevant hand-books and guidelines are used, but also a working process, which describes how the development work should be performed and the relationship between different parts in the process. The aim of this project was to present a general report in Swedish, which describes a working process for development of useful operator interfaces, work tasks, instructions, and working environments. The report is primarily aimed for the process industry, but can be useful in all other areas including interaction

    Knowing the risks, costs, and complexities associated with human missions to Mars, analogue research can be a great (low-risk) tool for exploring the challenges associated with the preparation for living, operating, and undertaking research in interplanetary missions. Short-duration analogue studies, such as those being accomplished at the Mars Desert Research Station (MDRS), offer the chance to study mission operations and human factors in a simulated environment, and therefore contribute to exploration of the Moon and Mars in planned future missions. This article is based upon previously published articles, abstracts, and presentations by a series of independent authors, human factor studies performed on mars analogue station by Crew 100B. The MDRS Crew 100B performed studies over 15 days providing a unique insight into human factor issues in simulated short-duration Mars mission. In this study, 15 human factors were evaluated and analyzed by subjective and objective means, and from the summary of results it was concluded that optimum health of an individual and the crew as a whole is a necessity in order to encourage and maintain high performance and the satisfaction of project goals.

    The question of the long-term safety of a repository system is inseparably linked with the intensive technical examination of the possible future evolution of the site and the repository system e. g. as a result of climatic, geologic, waste-related and repository-related processes. Here, the possible evolutions to be considered are those that have the potential to have a negative impact on the intended, furthest-possible, immediate, and lasting isolation of the radioactive waste in a defined area around the underground workings of the repository mine in salt rock, which is referred to as the containment-providing rock zone (CPRZ).

  11. Kv Channel S1-S2 Linker Working as a Binding Site of Human β-Defensin 2 for Channel Activation Modulation.

    Among the three extracellular domains of the tetrameric voltage-gated K(+) (Kv) channels consisting of six membrane-spanning helical segments named S1-S6, the functional role of the S1-S2 linker still remains unclear because of the lack of a peptide ligand. In this study, the Kv1.3 channel S1-S2 linker was reported as a novel receptor site for human β-defensin 2 (hBD2). hBD2 shifts the conductance-voltage relationship curve of the human Kv1.3 channel in a positive direction by nearly 10.5 mV and increases the activation time constant for the channel. Unlike classical gating modifiers of toxin peptides from animal venoms, which generally bind to the Kv channel S3-S4 linker, hBD2 only targets residues in both the N and C termini of the S1-S2 linker to influence channel gating and inhibit channel currents. The increment and decrement of the basic residue number in a positively charged S4 sensor of Kv1.3 channel yields conductance-voltage relationship curves in the positive direction by ∼31.2 mV and 2-4 mV, which suggests that positively charged hBD2 is anchored in the channel S1-S2 linker and is modulating channel activation through electrostatic repulsion with an adjacent S4 helix. Together, these findings reveal a novel peptide ligand that binds with the Kv channel S1-S2 linker to modulate channel activation. These findings also highlight the functional importance of the Kv channel S1-S2 linker in ligand recognition and modification of channel activation.

    humanización de los sujetos-trabajadores de las instituciones de salud.OBJECTIVE: To describe the perceptions of nursing professionals about humanization of their work process. METHODS: A qualitative research approach was used to conduct the study. Data were collected from seven nursing professionals of a Critical Care Unit of the Santa Casa de Misericórdia de Pelotas-RS, through semi-structured interviews. The data were analyzed, through successive readings and content analysis. Two themes have emerged: Humanization of the work process and gaps of the humanization of the work process. RESULTS: In the hospital, the humanization of the work process continues to place emphasis in the person-customer, yet little attention to the care and humanization of the person-worker. CONCLUSION: Humanization of the work process is widely discussed in literature; however, in practice, it depends on behavioral change and internalization of the need of humanization by the person-worker of health institutions.

    Background Although cervical cancer is the leading cancer in Cambodia, most women receive no routine screening for cervical cancer and few treatment options exist. Moreover, nothing is known regarding the prevalence of cervical HPV or the genotypes present among women in the country. Young sexually active women, especially those with multiple sex partners are at highest risk of HPV infection. We examine the prevalence and genotypes of cervical HPV, as well as the associated risk factors among young women engaged in sex work in Phnom Penh, Cambodia. Methods We conducted a cross-sectional study among 220 young women (15–29 years) engaged in sex work in different venues including brothels or entertainment establishments, and on a freelance basis in streets, parks and private apartments. Cervical specimens were collected using standard cytobrush technique. HPV DNA was tested for by polymerase chain reaction (PCR) and genotyping using type-specific probes for 29 individual HPV types, as well as for a mixture of 10 less common HPV types. All participants were also screened for HIV status using blood samples. Multivariate logistic regression analyses were conducted to assess risk factors for any or multiple HPV infection. Results The prevalence of cervical HPV 41.1%. HPV 51 and 70 were the most common (5.0%), followed by 16 (4.6%), 71 (4.1%) and 81 (3.7%). Thirty-six women (16.4%) were infected with multiple genotypes and 23.3% were infected with at least one oncogenic HPV type. In multivariate analyses, having HIV infection and a higher number of sexual partners were associated with cervical HPV infection. Risk factors for infection with multiple genotypes included working as freelance female sex workers (FSW) or in brothels, recent binge use of drugs, high number of sexual partners, and HIV infection. Conclusions This is the first Cambodian study on cervical HPV prevalence and genotypes. We found that HPV infection was common among young FSW, especially among women

    Prevention providers wonder whether benefits achieved in the original, researcher-led, efficacy trials of interventions are replicated when the intervention is delivered in real-world settings by their agency's staff. A replication study was conducted at 2 public sexually transmitted disease (STD) clinics (New York City and San Juan, PR). Using a controlled trial design, intervention (VOICES/VOCES) and comparison conditions (regular clinic services) were assigned in alternating 4-week blocks. Trained agency staff delivered the intervention. Effectiveness was assessed for incident STDs, redemption of coupons for condoms at neighborhood location after the visit, and improved knowledge and attitudes about STDs and condoms. A total of 3365 patients were recruited, completed the protocol, and followed through STD surveillance systems for an average of 17 months. Of 397 with an incident infection, 226 (13.4%) were among those enrolled during comparison blocks; 171 were among those in the intervention condition (10.2%). Controlling for site and gender, participants enrolled during intervention blocks were significantly less likely to have an incident STD reported to the surveillance system (hazard ratio, 0.78; 95% confidence interval, 0.64-0.96). Intervention block participants scored higher on scales of STD knowledge (4.89 vs. 3.87, P VOCES redeemed condoms (P < 0.05). Positive effects were more consistent in New York, which may be related to fidelity of implementation. A packaged human immunodeficiency virus prevention intervention can be delivered by agencies, with benefits similar to those achieved in the research setting.

    A precise guideline establishing chromosomal microarray analysis (CMA) applications and platforms in the prenatal setting does not exist. The controversial question is whether CMA technologies can or should soon replace standard karyotyping in prenatal diagnostic practice. A review of the recent literature and survey of the knowledge and experience of all members of the Italian Society of Human Genetics (SIGU) Committee were carried out in order to propose recommendations for the use of CMA in prenatal testing. The analysis of datasets reported in the medical literature showed a considerable 6.4% incidence of pathogenic copy number variations (CNVs) in the group of pregnancies with sonographically detected fetal abnormalities and normal karyotype. The reported CNVs are likely to have a relevant role in terms of nosology for the fetus and in the assessment of reproductive risk for the couple. Estimation of the frequency of copy number variations of uncertain significance (VOUS) varied depending on the different CMA platforms used, ranging from 0-4%, obtained using targeted arrays, to 9-12%, obtained using high-resolution whole genome single nucleotide polymorphism (SNP) arrays. CMA analysis can be considered a second-tier diagnostic test to be used after standard karyotyping in selected groups of pregnancies, namely those with single (apparently isolated) or multiple ultrasound fetal abnormalities, those with chromosomal rearrangements, even if apparently balanced, and those with supernumerary marker chromosomes.

    Human papillomavirus (HPV) causes cervical cancer and a large fraction of head and neck squamous cell carcinomas (HNSCC). Cidofovir (CDV) proved efficacious in the treatment of several HPV-induced benign and malignant hyper proliferations. To provide a better insight into how CDV selectively eradicates transformed cells, HPV+ and HPV− cervical carcinoma and HNSCC cell lines were compared to normal cells for antiproliferative effects, CDV metabolism, drug incorporation into cellular DNA, and DNA damage. Incorporation of CDV into cellular DNA was higher in tumor cells than in normal cells and correlated with CDV antiproliferative effects, which were independent of HPV status. Increase in phospho-ATM levels was detected following CDV exposure and higher levels of γ-H2AX (a quantitative marker of double-strand breaks) were measured in tumor cells compared to normal cells. A correlation between DNA damage and CDV incorporation into DNA was found but not between DNA damage and CDV antiproliferative effects. These data indicate that CDV antiproliferative effects result from incorporation of the drug into DNA causing DNA damage. However, the anti-tumor effects of CDV cannot be exclusively ascribed to DNA damage. Furthermore, CDV can be considered a promising broad spectrum anti-cancer agent, not restricted to HPV+ lesions.

    The NASA Constellation uncrewed cargo mission delivers cargo to any designated location on the lunar surface (or other staging point) in a single mission. This capability is used to deliver surface infrastructure needed for lunar outpost construction, to provide periodic logistics resupply to support a continuous human lunar presence, and potentially deliver other assets to various locations.In the nominal mission mode, the Altair lunar lander is launched on Ares V into Low Earth Orbit (LEO), following a short Low Earth Orbit (LEO) loiter period, the Earth Departure Stage (EDS) performs the Trans Lunar Injection (TLI) burn and is then jettisoned. The Altair performs translunar trajectory correction maneuvers as necessary and performs the Lunar Orbit Insertion (LOI) burn. Altair then descends to the surface to land near a designated target, presumably in proximity to an Outpost location or another site of interest for exploration.Alternatively, the EDS and Altair Descent Stage could deliver assets to various staging points within their propulsive capabilities.

    Although caring for residents with dementia in nursing homes is associated with various stressors for care workers, the role of the unit type, and particularly the proportion of residents with dementia, remains unclear. This study aimed to explore associations between unit type and care worker stress, taking into account additional potential stressors. This cross-sectional study was a secondary data analysis in the Swiss Nursing Homes Human Resources Project, which included data from 3,922 care workers from 156 Swiss nursing homes. Care workers' stress was measured with a shortened version of the Health Professions Stress Inventory. Generalized estimating equation models were used to assess care worker stress and its relationships with three unit types (special care units and others with high or low proportions of residents with dementia), work environment factors, and aggressive resident behavior. After including all potential stressors in the models, no significant differences between the three unit types regarding care worker stress were found. However, increased care worker stress levels were significantly related to lower ratings of staffing and resources adequacy, the experience of verbal aggression, and the observation of verbal or physical aggression among residents. Although the unit type plays only a minor role regarding care worker stress, this study confirms that work environment and aggressive behavior of residents are important factors associated with work-related stress. To prevent increases of care worker stress, interventions to improve the work environment and strengthen care workers' ability to cope with aggressive behavior are suggested.

    During the past two decades, mercury has come under increasing scrutiny with regard to its safety both in the general population and in occupationally exposed groups. It's a growing issue of global concern because of its adverse environmental and health impacts. Very few investigations on mercury amalgam use in the dentistry sector have been carried out in South Asia and there is little data reported on mercury contamination of indoor/outdoor air at dental sites. According to an earlier SDPI study, reported in 2013, alarmingly high mercury levels were observed in air (indoor as well as outdoor) at 11 of the 34 visited dental sites (17 dental teaching institutions, 7 general hospitals & 10 dental clinics) in five main cities of Pakistan. 88% of the sites indicated indoor mercury levels in air above the USA EPA reference level of 300 ng/m3. According to our study, carried out at 38 dental teaching institutions in 12 main cities (in Khyber Pakhtunkhwa, Punjab and Sindh provinces) of Pakistan, respondents were of the opinion that the currently offered BDS curriculum does not effectively guide outgoing dental professionals and does not provide them adequate knowledge and training about mercury/mercury amalgam and other mercury related human health and mercury waste issues. 90% of respondents supported the review and revision of the present dental curriculum offered at dental teaching institutions in the country, at the earliest. A study has also been conducted to assess the status of mercury amalgam use in private dental clinics in Gilgit, Hunza, Peshawar, Rawalpindi and Islamabad. More than 90 private dental clinics were visited and dental professionals/private clinics in-charge were interviewed during June-July, 2015. The focus areas of the study were Hg amalgam toxicity, its waste management practices and safety measures practiced among the dental practitioners. In the light of the findings described and discussed in this brief report, to safeguard public health and

    Identifying individual species or determining species' composition in an unknown sample is important for a variety of forensic applications. Food authentication, monitoring illegal trade in endangered species, forensic entomology, sexual assault case work and counter terrorism are just some of the fields that can require the detection of the biological species present. Traditional laboratory based approaches employ a wide variety of tools and technologies and exploit a number of different species specific traits including morphology, molecular differences and immuno-chemical analyses. A large number of these approaches require laboratory based apparatus and results can take a number of days to be returned to investigating authorities. Having a presumptive test for rapid identification could lead to savings in terms of cost and time and allow sample prioritisation if confirmatory testing in a laboratory is required later. This model study describes the development of an assay using a single HyBeacon(®) probe and melt curve analyses allowing rapid screening and authentication of food products labelled as Atlantic cod (Gadus morhua). Exploiting melt curve detection of species specific SNP sites on the COI gene the test allows detection of a target species (Atlantic cod) and closely related species which may be used as substitutes. The assay has been designed for use with the Field Portable ParaDNA system, a molecular detection platform for non-expert users. The entire process from sampling to result takes approximately 75min. Validation studies were performed on both single source genomic DNA, mixed genomic DNA and commercial samples. Data suggests the assay has a lower limit of detection of 31 pg DNA. The specificity of the assay to Atlantic cod was measured by testing highly processed food samples including frozen, defrosted and cooked fish fillets as well as fish fingers, battered fish fillet and fish pie. Ninety-six (92.7%) of all Atlantic cod food products

    el estudio de la neuropsicología y el desarrollo humano.The present text appears as a theoretical essay on the subject of human development as depicted in the work of Lev Vygotsky and approaches the implications of this issue for Neuropsychology as described in the work of Alexander Luria. This work was conducted on the basis of the complete works of Vygotsky in Spanish and the works of Vygotsky and Luria in the Portuguese language. Considerations about the functioning of the human brain, the concept of compensation, the disability studies, and the concept of Complex Functional System were selected as the focus of our research. Although numerous studies and different translations of the work of Vygotsky have a considerable impact and dissemination, especially in the fields of psychology and education, issues concerning neuropsychology have not had equal importance. In this context, this paper seeks to highlight the contributions and the fruitfulness of the work with regard to the originality of the author's ideas about the study of neuropsychology and human development.

    Full Text Available Background/Aim. Occupational stress is a term used to define ongoing stress that is related to the workplace. The study was conducted to determine association of occupational stress index (OSI and its aspects with arterial hypertension and lipid disorders using data from a cross-sectional survey of male professional drivers. Methods. The cross-sectional study was performed in 439 professional drivers divided into groups (city- and intercity bus drivers, truck and taxi drivers. The OSI and OSI aspects (high demands, strictness, underload, extrinsic time pressure, noxious exposure, avoidance and conflict were calculated using the standardized questionnaire. Determination of serum lipids, blood pressure (BP and cardiovascular risk factors were done. Results. A significant difference in prevalence of diagnosed hypertension and dyslipidemia was found along with a difference in total OSI and OSI aspects among examined subgroups of drivers. A total OSI was highest in city, high in intercity bus drivers, and the lowest one in truck and taxi drivers (82.79 ± 3.5, 81.28 ± 3.7, 73.75 ± 3.5, 71.61 ± 4.4, respectively; p < 0.01. Similar pattern showed triglycerides (TG, total cholesterol (TC and LDL cholesterol and BP, while HDL-cholesterol showed reverse order (p < 0.01. Logistic regression analyses with multiple OSI aspects adjusted for age and years of exposure showed associations of total OSI with arterial hypertension [OR 5.5; 95% CI (2.24-7.95] and dyslipidemia [OR 1.43 95% CI (1.09-2.80]. Underload was the most important OSI aspect associated with the arterial hypertension [OR 1.18; 95% CI (1.04-2.58] and elevated LDL cholesterol [1.26; 95 CI (1.19-2.1]. A total OSI had a significant association with elevated LDL cholesterol [2.64; 95% CI (1.19- 7.7], triglycerides [OR 3.27; 95% CI (1.20-5.1] and low HDL cholesterol [OR 3.29; 95% CI (1.8-5.8] (p < 0.01.

  8. Impact of the workers' loyalty on the group performance modeled by a bi-layer cellular automaton with a hysteretic rule

    Malarz, Krzysztof; Kułakowski, Krzysztof

    2014-01-01

    The problem `human and work' in a model working group is investigated by means of cellular automata technique. Attitude of members of a group towards work is measured by indicator of loyalty to the group (the number of underloaded agents who carry out their tasks), and lack of loyalty (the number of overloaded agents, who give their tasks to other agents). Initially, all agents realize scheduled tasks one-by-one. Agents with the number of scheduled tasks larger than a given threshold change their strategy to `overloaded' one and start avoiding completing tasks by passing them to their colleagues. Optionally, in some conditions, we allow agents to return to `underloaded' state; hence the rule is hysteretic. Results are presented on an influence of i) the density of tasks, ii) the threshold number of tasks assigned to the agents' forcing him/her for strategy change on the system efficiency. We show that a `black' scenario of the system stacking in a jammed phase (with all agents being in overloaded state and ha...

  14. Wage Slavery or Creative Work?

    Science.gov (United States)

    Mirowsky, John

    2011-07-01

    Western philosophical and scientific traditions often view human work as inherently onerous, wearisome, and degrading. Adam Smith, writing in the eighteenth century, saw work as the toil and trouble that is the real price humans pay for everything they need or want. Karl Marx, writing in the nineteenth century, considered wage labor alienating, but saw the possibility of self-expressive work. Dupré and Gagnier, a philosopher and a critic writing near the end of the twentieth century, agreed that work could be self-fulfilling, but only for an elite minority. This article summarizes the Western philosophical views of work from ancient to modern times. It reframes the philosophical positions as empirical questions and addresses them with statistics and models drawn from a 1995 U.S. survey. Observations suggest that work, in modern America, is not usually alienated. The great majority of Americans rate their paid work or other main daily activities (mostly unpaid work) as more autonomous and creative than not. Emotional well-being and the sense of control over one's own life increase with the degree of autonomy and creativity. The employed report less autonomous but more creative activity than do the nonemployed. Emotional well-being and perceived control correlate more strongly with creativity than with autonomy. The overall association thus favors employment, especially for the poorly educated, even though they give up more autonomy when employed. On the whole, work in modern America seems more self-fulfilling than onerous, alienating, or degrading.

    situations necessitate that crewmembers wake from sleep and make quick decisions. A recently completed BHP investigation assesses the effects of sleep inertia upon abrupt awakening, with and without hypnotics currently used in spaceflight; results from this investigation will help to inform strategies relative to sleep inertia effects on performance. Circadian desynchrony has been observed during spaceflight. Circadian desynchrony during spaceflight develops due to schedule constraints requiring non-24 operations or 'slam-shifts' and due to insufficient or mis-timed light exposure. In addition, circadian misalignment has been associated with reduced sleep duration and increased medication use. In ground-based studies, circadian desynchrony has been associated with significant performance impairment and increased risk of accidents when operations coincide with the circadian nadir. There is a great deal of information available on how to manage circadian misalignment, however, there are currently no easily collected biomarkers that can be used during spaceflight to determine circadian phase. Current research efforts are addressing this gap. Work overload has been documented during current spaceflight operations. NASA has established work hour guidelines that limit shift duration, however, schedule creep, where duty requirements necessitate working beyond scheduled work hours, has been reported. This observation warrants the documentation of actual work hours in order to improve planning and in order to ensure that astronauts receive adequate down time. In addition to concerns about work overload, ground based evidence suggests that work underload may be a concern during deep space missions, where torpor may develop and physically demanding workload will be exchanged for monitoring of autonomous systems. Given that increased automation is anticipated for exploration vehicles, fatigue effects in the context of such systems needs to be further understood. Performance metrics are

From the perspective of the national Working Group, the current article describes the essential steps in the development, implementation and evaluation of the Federal Licensing Examination Clinical Skills (FLE CS as well as the applied quality assurance measures. Finally, central insights gained from the last years are presented. Methods: Based on the principles of action research, the FLE CS is in a constant state of further development. On the foundation of systematically documented experiences from previous years, in the Working Group, unresolved questions are discussed and resulting solution approaches are substantiated (planning, implemented in the examination (implementation and subsequently evaluated (reflection. The presented results are the product of this iterative procedure.Results: The FLE CS is created by experts from all faculties and subject areas in a multistage process. The examination is administered in German and French on a decentralised basis and consists of twelve interdisciplinary stations per candidate. As important quality assurance measures, the national Review Board (content validation and the meetings of the standardised patient trainers (standardisation have proven worthwhile. The statistical analyses show good measurement reliability and support the construct validity of the examination. Among the central insights of the past years, it has been established that the consistent implementation of the principles of action research contributes to the successful further development of the examination.Conclusion: The centrally coordinated, collaborative-iterative process, incorporating experts from all faculties, makes a fundamental contribution to the quality of the FLE CS. The processes and insights presented here can be useful for others planning a

    2014-12-01

    Full Text Available There is a significant shift of approach to the management of organizations and workers in recent decades. This shift in management philosophy is characterized by converting from traditional, conventional (rather bureaucratic management models to rather humanistic/existential oriented models. This transition comes partly from the understanding that human resources are the most promising and effective way for organization development, partly from a shift in the understanding of the role of organizations in society. The key point of these approaches has become a "meaning" or "meaningfulness" in relation to the work and organization. The importance of work meaningfulness is not only in its potential to increase the competitiveness of organizations, but especially in its major (mostly positive impacts on the employee himself and his work (and by that the organization and its performance. Work meaningfulness is strongly connected to the work engagement, which represents the active personal participation in the work process, manifested by vigor, active cooperation, willingness to contribute to the company's success and dedication to work. Work engagement seems to be next important factor affecting work attitudes and achievements of employees. The paper gives an overview of various approaches to work meaningfulness and work engagement, on the basis of which authors propose new model of work meaningfulness with overlap to work engagement. The work meaningfulness is not seen as one-dimensional variable, but consists of complex of interacting factors and processes that define an individual perceived meaning and importance of the work. Meaningful work is influenced by three areas. The first is the organizational culture. This is defined as a specific pattern of values, norms, beliefs, attitudes and assumptions that are often not clearly expressed, but affect the way individuals behave in an organization and how things are done. The second area is the work

    Many individuals of working age experience cardiovascular disease and are disabled from work as a result. The majority of research in cardiac work disability has focused on individual biological and psychological factors influencing work disability despite evidence of the importance of social context in work disability. In this article, the focus is on work and organisational features influencing the leeway (margin of manoeuvre) workers are afforded during work reintegration. A qualitative method was used. A large auto manufacturing plant was selected owing to work, organisational, and worker characteristics. Workplace context was assessed through site visits and meetings with stakeholders including occupational health, human resources and union personnel and a review of collective agreement provisions relating to seniority, benefits and accommodation. Worker experience was assessed using a series of in-depth interviews with workers (n = 12) returning to work at the plant following disabling cardiac illness. Data was analysed using qualitative content analysis. Workers demonstrated variable levels of adjustment to the workplace that could be related to production expectations and work design. Policies and practices around electronic rate monitoring, seniority and accommodation, and disability management practices affected the buffer available to workers to adjust to the workplace. Work qualities and organisational resources establish a margin of manoeuver for work reintegration efforts. Practitioners need to inform themselves of the constraints on work accommodation imposed by work organisation and collective agreements. Organisations and labour need to reconsider policies and practices that creates unequal accommodation conditions for disabled workers. Implications for rehabilitation Margin of manoeuvre offers a framework for evaluating and structuring work reintegration programmes.

We see stories as central to engagement with the development and evaluation of theories, and we argue that for a story to be useful in this way, it should be anomalous (representing aspects of life that are not well explained by existing models) and immutable (with details that are well...

However ,this history is not sufficiently propagated and valuated .Thus ,the author of the novel carried out a number of artistic explorations to demonstrate the Chinese people's moral sublimation beyond the egotis‐tic nationalism to the universal human consciousness from the characters of Pan Jintang and Xie Donghong . Regarded as a profound fable ,it not only described the cross‐ethnic rescue full of human love ,but also crea‐ted many fable words that cannot easily be deciphered .Therefore ,the novel might be considered as a work of fate of a nation through the deeper interpretations of its connotation .

    Natural science and human science are identified as the bases of most nursing theories and research programs. Natural science has been disclaimed by Martha Rogers as the philosophy of science that undergirds her work. The question remains, is the science of unitary human beings an interpretive human science? The author explores the works of Rogers through a dialectic with two human scientists' works. Wilhelm Dilthey's works represent the founding or traditional view, and Jurgen Habermas' works represent a contemporary, reconstructionist view. The ways Rogerian thought contributes to human studies but is distinct from traditional and reconstructionist human sciences are illuminated.

    Full Text Available Islamic principles completely cover all prospects of life including working in organization. The impact of management style used in an organization play an important role in employee commitment towards its work. This paper is an effort to explore impact of Islamic work ethic on human resource of organization including the prospective of work conflict, job satisfaction, job turn over, turnover intentions and organizational commitment. Data for current study was collected personally through questionnaires from 18 branches of seven banks of Pakistan who practices Islamic banking. In total, 150 Muslims employees were targeted as respondent of current study, while response rate was above 85%. Results show that there is significant impact of Islamic work ethics on organizational commitment, job satisfaction and rewards while Islamic work ethic has no significant relation with intention to quit job. Out of seven, only three hypotheses were fully supported, while two were partially supported, however number of rejected hypothesis were two. Islamic work ethics are source to built greater morale in employees resulting greater job satisfaction. Adopting Islamic work ethics improves organizational commitment, source of motivation as well as reduces the negative intentions of quitting job.

    de Souza, Rosangela Ferreira; Matias, Hernani Aparecido; Brêtas, Ana Cristina Passarella

    2010-09-01

    This qualitative research has the aim to know the meaning of the aging process in the work market referring to the aged people. Six aged persons have participated in this research. The data were collected through an interview and were analyzed using the technique of thematically analyze. Three analytical categories emerged: the meaning of aging/to be aged; the meaning of work; the meaning of aging in the work. Concluding, this paper reinforces the theory that the capitalist societies attach excessive value to the work in the human being life. When it isn't into the life--because of the retirement or the unemployment--it compromises the quality of aging/to be aged of the person, mainly if skills and (individual, social and economical) conditions will lack participation and priority to others activities and values in her/his life.

  19. Work engagement and meaningful work across generational cohorts

    Directory of Open Access Journals (Sweden)

    Crystal Hoole

    2015-03-01

    Full Text Available Orientation: Engaging employees and providing employees with a sense of meaning at work is not a one-size-fits-all approach. Although research has shown that differences between work engagement and meaningful work amongst generational cohorts exist, results are still inconclusive. With age becoming increasingly more important as a diversity factor, a better understanding of the dynamics between work engagement and meaningful work across different generational cohorts is necessary to design the right strategy for each organisation’s unique parameters.Research purpose: The aim of this study was to determine whether there is a relationship between work engagement and meaningful work and whether there are significant variances between the levels of work engagement and meaningful work between different generational cohorts.Motivation for study: Work engagement has consistently been highlighted by researchers and human resources experts as a recommended solution to provide companies with the upper hand when it comes to creating a competitive edge. Yet, levels of work engagement are far from ideal, requiring intensified efforts to identify solutions towards raising overall engagement levels. In recent years, much of the focus in terms of generating engagement has been aimed in the direction of financial rewards and other benefits; some organisational experts are of the opinion that a shift is occurring towards meaningful work instead of monetary rewards as the driver of engagement. The changing nature of the work landscape also suggests that generational cohorts experience work engagement and meaningful work differently. Understanding these complexities is mandatory in creating solutions towards improving levels of engagement and meaningful work.Research approach, design and method: A cross-sectional quantitative research approach has been followed. The Utrecht Work Engagement Scale (UWES and Psychological Meaningful Scale (PMS were administered to

    Due to the flexibility and adaptability of human, manual handling work is still very important in industry, especially for assembly and maintenance work. Well-designed work operation can improve work efficiency and quality; enhance safety, and lower cost. Most traditional methods for work system analysis need physical mock-up and are time consuming. Digital mockup (DMU) and digital human modeling (DHM) techniques have been developed to assist ergonomic design and evaluation for a specific worker population (e.g. 95 percentile); however, the operation adaptability and adjustability for a specific individual are not considered enough. In this study, a new framework based on motion tracking technique and digital human simulation technique is proposed for motion-time analysis of manual operations. A motion tracking system is used to track a worker's operation while he/she is conducting a manual handling work. The motion data is transferred to a simulation computer for real time digital human simulation. The data ...

    For years, the writing has been on the wall about the impact of climate change on the people, plants, animals, and habitats of Latin America and the Caribbean. Now, day-to-day experiences and eye-witness accounts from leading environmental and development groups are proving predictions to be correct. In the late 1990s, the world's pre-eminent group of climate scientists gathered under the Intergovernmental Panel on Climate Change (IPCC) and predicted a devastating range of impacts, including an increase in the intensity and number of extreme weather events exacerbating natural disasters, forest die-off, melting glaciers, and the drying out of temperate grasslands. The region's huge geographical diversity means that patterns of vulnerability to climate change are extremely varied. It also makes modelling difficult, although this is constantly improving. To avoid misunderstanding, it is important to point out that with or without global warming, extreme weather is a problem for the people of the region. For many people, however, climate change is set to turn an already rough ride into an impossible one. This report confirms that temperature and rainfall patterns, hitherto largely regular and predictable, are changing and becoming less predictable and often more extreme. Based upon the experiences of partner agencies and the people they work with across the region, this report catalogues impacts linked to both climate change and environmental degradation ranging from drought in the Amazon to floods in Haiti and elsewhere; from vanishing glaciers in Colombia to extreme cold in the Andes; and hurricanes, not only in Central America and the Caribbean, but also in southern Brazil. It examines the impacts on agriculture and farming practices, fishing and coastal zones, towns and cities, and on the people of Latin America and the Caribbean: peasants, indigenous peoples, women, town dwellers, migrants. The direct and indirect impacts catalogued include the loss and

  6. Medicine and the sexual division of labour: An analysis of the scientific discourse on the role of the "human factor" in improving performance at work (Spain 1920-1950

    Directory of Open Access Journals (Sweden)

    Martínez Pérez, José

    2008-06-01

    Full Text Available During the first third of the twentieth century, and especially after the 1920s, a discourse on occupational hygiene and safety began to develop in Spain. This discourse, without rejecting the value of the work carried out in the factory environment, particularly stressed the need to take into account what was called the «human factor». Promoted mainly by the budding occupational doctors and psychologists, this discourse became part of both the lines of biological thinking of constitutional pathology as well as the economic ideas of the so-called OCT, and it expounded the need to take the somatic and psychic characteristics of people into account in order to carry out a «rational» distribution of the same in the workplace. The article aims to highlight the way in which this discourse contained elements that would help to attribute specific roles within the workplace based on the biological and psychological characteristics of men and women, so facilitating the legitimisation of a sexual distribution of work which helped to reinforce the social organisation of gender at that time.

    A lo largo del primer tercio del siglo XX, y especialmente a partir de la década de los años veinte, se empezó a difundir en España un discurso sobre la higiene y seguridad en el trabajo que, aun sin rechazar el valor de la actuación sobre el medio ambiente fabril, hacía especial hincapié en la necesidad de tomar en cuenta lo que denominaban como «factor humano». Impulsado fundamentalmente por los incipientes médicos y psicólogos del trabajo, este discurso quedó enmarcado tanto en las corrientes de pensamiento biológico de la patología constitucional, como en las ideas económicas de la llamada Organización Científica del Trabajo, y planteó la necesidad de tomar en cuanta las características somáticas y psíquicas de las personas para llevar a cabo una distribución «racional» de las mismas en el mercado de trabajo.

    In order to improve responsibility of the workers for strict observance of the standards, rules and instruction for work safety, the Karlov NKGRE has introduced a number of indicators under socialist competition: lack of injuries, accidents, complications, fulfillment of organizational-technical measures of a comprehensive plan and collective contract, preventive maintenance schedule and instructions of the agencies of inspection and public inspectors. The organization of prevention of production injury is based on the principle ''for each object constant attention to work safety and supervisory monitoring.'' Monitoring of the condition of accident prevention is done by 69 public inspectors under the control of the commission of work safety made of 9 people. The work of the commission is done according to quarterly and annual plans. The commission reveals shortcomings, introduces specific suggestions, for example regarding reconstruction of the ventilation of the sharpener, the mechanism of pipe feed to the pipe cutting machine, etc. One of the main tasks of the commission is to participate in the rapid control of the condition of work safety at the work sites. For achievements in work to create good working and living conditions, the collective of the Karlov NKGRE was awarded certificates of the AUCCTU, the Ukrainian SSR Ministry of Geology and the USSR Ministry of Geology, as well as group and republic committees of the trade unions.

    Full Text Available I have been photographing my children, Eden and Emmanuelle since I got pregnant in 2003. I photograph as a mother, from a mother's point of view, showing the different aspects of motherhood as I see them; the beautiful and the ugly, the magic and the frustration, the extremes that live side by side when you are a mother. I try to photograph them all. Crying, sadness, anxiety, mourning the body I will never have again, the woman I will never be again. The strong physical connection to the children, erotic at times, something I found out many mothers experience but do not talk about much. With my images I try to sing a love song to my children, they are my inspiration. Their love, sadness, joy and neediness are for me the most meaningful moments of my life, the moments I want to photograph and preserve. Those images are taken from my life, they are very personal, they are about being a mother, being a child, the intensity of raising a child. This work is about the essence of being human.

Robots can perform precursor tasks, such as reconnaissance, which help prepare for future human activity. Robots can work in support of astronauts, assisting or performing tasks in parallel. Robots can also perform "follow-up" work, completing tasks designated or started by humans. In this paper, we summarize the development and testing of robots designed to improve future human exploration of space.

  4. Maritime Work and Communication

    Full Text Available This paper presents findings from the project "Elastic Systems" under the Danish Center for Human Machine Interaction. The project aims at developing methods for analyzing dynamic maritime work processes and for designing flexible instrument interfaces that will support changing work environments. Here I only address the former issue, the design issues being published elsewhere, e.g. in Andersen(1999 and Andersen & May (2001. More data can be found in Andersen(2000. The purpose of the present paper is twofold: (1 to present characteristics of maritime work and communication, and (2 to suggest a conceptual framework that covers communicative as well as non-communicative acts. The latter purpose is motivated in two ways. Theoretical motivation: we know that language is self-referential, so that it can speak of non-linguistic entities like ships and waves as well as its own properties, such as the correct wording or style. The easiest way to accomplish this is for language to treat both domains in a similar way. The other motivation is more practical: it is a fact that communication and physical actions are interwoven in maritime work, and a theory that builds on a sharp distinction between these two kinds of behaviors will miss this basic characteristic. The data is from a voyage aboard Sally Maersk from Algeciras to Goteborg and back to Rotterdam. We recorded 60 hours of high quality video, and the paper builds upon a 16 hours trip from Felixstowe to Rotterdam, supplemented by data from simulated voyages in the simulator at the Danish Maritime Institute. The conceptual framework is based on Lind 1994 and Lind 2000 and distinguishes between the following types of action types: (1 Prevent(suppress, avoid: if I hadn't done it, then an undesirable state would have developed. Prevent drifting by using auxiliary rudder. (2 Maintain: if I hadn't done it, then a desirable state would have disappeared. Maintain course. (3 Help: a positive state would have

    OBJECTIVES: According to the "stress-as-offense-to-self" perspective, work tasks that are considered unnecessary or unreasonable - so-called "illegitimate work tasks" - are likely to elicit stress-reactions. Previous studies, mostly cross-sectional, have shown that illegitimate tasks are associated...... with increased self-reported stress, cortisol, and counterproductive work behavior. In this article, we examine the prospective association between unnecessary work tasks, one type of illegitimate work tasks, and mental health among Danish human service workers. Further, we explore whether this association...... is modified by sex, age, occupational position, and baseline mental health status. METHODS: The data were obtained from self-administered questionnaires from 1351 Danish human service workers in three waves of data-collection during 1999-2005.

    Work attitudes have been associated with work productivity. In health care, poor work attitudes have been linked to poor performance, decreased patient safety, and quality care. Hence, the importance, ascribed in the literature, of work that clearly identifies the relationships between and among work attitudes and work behaviors linked to performance. The purpose of this study is to better understand the relationships between work attitudes-perceived organizational justice, perceived organizational support (POS), affective commitment-consistently associated with a key type of performance outcome among nurses' organizational citizenship behaviors (OCBs). A survey was developed and administered to frontline nurses working in the province of Ontario, Canada. Data analysis used path analytic techniques. Direct associations were identified between interpersonal justice and POS, procedural justice and POS, and POS and affective commitment to both one's supervisor and one's co-workers. Affective commitment to patients and career was directly associated with OCBs. Affective commitment to one's co-worker was directly associated with OCBs directed toward individuals, as affective commitment to one's organization was with OCBs directed toward the organization. Finally, OCBIs and OCBs were directly associated. Examining the relationships of these constructs in a single model is novel and provides new information regarding their complexity. Findings suggest that prior approaches to studying these relationships may have been undernuanced, and conceptualizations may have led to somewhat inaccurate conclusions regarding their associations. With limited resources, knowledge of nurse work attitudes can inform human resource practices and operational policies involving training programs in employee communication, transparency, interaction, support, and performance evaluation.

    In the last ten years the concepts of health and mental health have been considerably modified and mental health at work is becoming an important interest of the in this field. However, it is difficult to establish with certainty the cause and effect between work and mental health problems since many other factors could possibly be responsible for the onset of those problems. Since work constitutes the principal activity of the human being it is reasonable that it could affect its mental equilibrium. Ergonomy deals with the person at work with the aim of better adapting the work to his needs, capacities and aspirations.

    Identification was intended on effects of such thermal factors as metabolic amount, environmental temperature and humidity, and clothing resistance on human body temperatures during works under hot environments. Therefore, measurements were carried out on human skin temperatures, rectum temperatures and humidity inside clothing, while amount of motion, environmental temperature, and clothing are changed in a constant temperature room and under a sun irradiation environment. Furthermore, a heat balance model was prepared, which divides the objects into an outer shell layer whose temperature changes depending on the result of this experiment and into a core having constant temperature characteristics. An equation to derive skin temperatures was introduced from the model. The equation formulated a calculation formula for heat accumulation in human body, which can be used as a hot heat index. Relationship between thermal factors and heat storage amount was investigated to consider a thermal limit for a physical work. An equation to derive skin temperatures was confirmed capable of expressing general change in skin temperatures, being proved by comparison with experiments. Calculation formulas for amount of heat stored in human body were shown capable of expressing influence of different thermal factors, the expression being useful as a hot heat index. Calculating the human body heat storage is very largely affected by effect of sweat to dissipate heat, hence it is necessary to improve the accuracy including that for body temperature adjusting reactions. 17 refs., 17 figs., 5 tabs.

Work can be conceived as a source of creation, transformation and human emancipation, but it can also take its negatives aspects, that ones connected with tripalium. In the Capitalism, where work is connected essentially with a mere factor of production, appear easily its negatives connotations. By the other hand, principles of alternatives models as the solidary economy, of equality and autonomy, for instance, can get back the work’s humanization.

  11. Selective attention, working memory, and animal intelligence.

    Matzel, Louis D; Kolata, Stefan

    2010-01-01

    Accumulating evidence indicates that the storage and processing capabilities of the human working memory system co-vary with individuals' performance on a wide range of cognitive tasks. The ubiquitous nature of this relationship suggests that variations in these processes may underlie individual differences in intelligence. Here we briefly review relevant data which supports this view. Furthermore, we emphasize an emerging literature describing a trait in genetically heterogeneous mice that is quantitatively and qualitatively analogous to general intelligence (g) in humans. As in humans, this animal analog of g co-varies with individual differences in both storage and processing components of the working memory system. Absent some of the complications associated with work with human subjects (e.g., phonological processing), this work with laboratory animals has provided an opportunity to assess otherwise intractable hypotheses. For instance, it has been possible in animals to manipulate individual aspects of the working memory system (e.g., selective attention), and to observe causal relationships between these variables and the expression of general cognitive abilities. This work with laboratory animals has coincided with human imaging studies (briefly reviewed here) which suggest that common brain structures (e.g., prefrontal cortex) mediate the efficacy of selective attention and the performance of individuals on intelligence test batteries. In total, this evidence suggests an evolutionary conservation of the processes that co-vary with and/or regulate "intelligence" and provides a framework for promoting these abilities in both young and old animals.

    2000-01-01

    This paper presents excerpts of the speeches delivered by International Labor Organization (ILO) Director-General Juan Somavia during the meetings in New Delhi, Washington, Bangkok and Durban. Overall, Somavia's speeches focused on several key policy statements of ILO. In one of his addresses, it was noted that ILO was not just about labor standards and trade, but also about a decent work agenda, which includes the promotion of fundamental human rights at work. Although the concept of decent work can contribute to such an integrated approach to policy, it can be of use to the comprehensive development framework being developed by the World Bank. Together, the mandates, perspectives and skills of the Bank and the ILO could make a start by working on how to integrate the agendas of poverty reduction and decent work. Moreover, it has been highlighted that the ILO are initiating to implement basic principles on freedom of association, forced labor, discrimination, and child labor. In terms of globalization, the task of the ILO is to shape the process so that the power and potential of the global market, the knowledge economy and the network society reaches every nation, every village, and every household.

  14. Conserving tigers in working landscapes.

    Tiger (Panthera tigris) conservation efforts in Asia are focused on protected areas embedded in human-dominated landscapes. A system of protected areas is an effective conservation strategy for many endangered species if the network is large enough to support stable metapopulations. The long-term conservation of tigers requires that the species be able to meet some of its life-history needs beyond the boundaries of small protected areas and within the working landscape, including multiple-use forests with logging and high human use. However, understanding of factors that promote or limit the occurrence of tigers in working landscapes is incomplete. We assessed the relative influence of protection status, prey occurrence, extent of grasslands, intensity of human use, and patch connectivity on tiger occurrence in the 5400 km(2) Central Terai Landscape of India, adjacent to Nepal. Two observer teams independently surveyed 1009 km of forest trails and water courses distributed across 60 166-km(2) cells. In each cell, the teams recorded detection of tiger signs along evenly spaced trail segments. We used occupancy models that permitted multiscale analysis of spatially correlated data to estimate cell-scale occupancy and segment-scale habitat use by tigers as a function of management and environmental covariates. Prey availability and habitat quality, rather than protected-area designation, influenced tiger occupancy. Tiger occupancy was low in some protected areas in India that were connected to extensive areas of tiger habitat in Nepal, which brings into question the efficacy of current protection and management strategies in both India and Nepal. At a finer spatial scale, tiger habitat use was high in trail segments associated with abundant prey and large grasslands, but it declined as human and livestock use increased. We speculate that riparian grasslands may provide tigers with critical refugia from human activity in the daytime and thereby promote tiger occurrence

    The Work Coordination Engine (WCE) is a Java application integrated into the Service Management Database (SMDB), which coordinates the dispatching and monitoring of a work order system. WCE de-queues work orders from SMDB and orchestrates the dispatching of work to a registered set of software worker applications distributed over a set of local, or remote, heterogeneous computing systems. WCE monitors the execution of work orders once dispatched, and accepts the results of the work order by storing to the SMDB persistent store. The software leverages the use of a relational database, Java Messaging System (JMS), and Web Services using Simple Object Access Protocol (SOAP) technologies to implement an efficient work-order dispatching mechanism capable of coordinating the work of multiple computer servers on various platforms working concurrently on different, or similar, types of data or algorithmic processing. Existing (legacy) applications can be wrapped with a proxy object so that no changes to the application are needed to make them available for integration into the work order system as "workers." WCE automatically reschedules work orders that fail to be executed by one server to a different server if available. From initiation to completion, the system manages the execution state of work orders and workers via a well-defined set of events, states, and actions. It allows for configurable work-order execution timeouts by work-order type. This innovation eliminates a current processing bottleneck by providing a highly scalable, distributed work-order system used to quickly generate products needed by the Deep Space Network (DSN) to support space flight operations. WCE is driven by asynchronous messages delivered via JMS indicating the availability of new work or workers. It runs completely unattended in support of the lights-out operations concept in the DSN.

  15. Live to work or love to work: work craving and work engagement.

    Directory of Open Access Journals (Sweden)

    Kamila Wojdylo

    Full Text Available OBJECTIVE: According to the theory of work craving, a workaholic has a craving for self-worth compensatory incentives and an expectation of relief from negative affect experienced through neurotic perfectionism and an obsessive-compulsive style of working. Research has shown that workaholism and work engagement should be considered as two distinct work styles with different health consequences. However, the mechanisms underlying the adoption of these work styles have been neglected. The present study proposes that work craving and work engagement are differentially associated with self-regulatory competencies and health. In particular, we expected that the working styles mediate the relationships between emotional self-regulation and health. METHODS: In the cross-sectional study, 469 teachers from German schools completed online administered questionnaires. By means of structural equation modeling, we tested two indirect paths: a from self-relaxation deficits via work craving to poor health and b from self-motivation competencies via work engagement to good health. RESULTS: As expected, we found evidence that a the negative relationship of self-relaxation deficits on health was partially mediated by work craving and b the positive relationship of self-motivation competencies on health was partially mediated by work engagement. CONCLUSIONS: The present study emphasizes the importance of self-regulation competencies for healthy or unhealthy work styles. Whereas work craving was associated with a low ability to down-regulate negative emotions and poor health, work engagement was associated with a high ability to up-regulate positive emotions and good health.
