Work organization patterns and working conditions experienced by nursing personnel in the hospital settings may be associated to increased morbidity among these health workers. To estimate the prevalence and factors associated with self-reported diseases among nursing personnel at the emergency hospital in Rio Branco/State of Acre, Brazil. A cross-sectional study was conducted involving 272 participants who answered a questionnaire including sociodemographic characteristics, working conditions, lifestyles, work ability, and a fatigue perception scale. The self-reported diseases in the 12 months prior to data collection were considered the dependent variable. A total of 85.7% of the participants reported one or more diseases in the past 12 months. Most prevalent diseases were: musculoskeletal diseases (37.1%), digestive diseases (28.7%), mental disorders (28.3%), work injuries (27.9%), and respiratory diseases (26.8%). The following significant variables remained in the final model: high work demands (OR 2.69), reported fatigue (OR 3.59), night work (OR 6.55) and being a technician or nursing assistant (OR 4.23). Variables related to working conditions and work organization were associated with the occurrence of reported diseases among nursing professionals. Health promotion measures at work require a comprehensive approach including the working conditions and the work organization.

New systems of work organization and workers' health.

PubMed

Kompier, Michiel A J

2006-12-01

This paper aims at identifying major changes in and around work organizations, their effects upon job characteristics and the health and well-being of today's employees, and related research challenges. Increased internationalization and competition, increased utilization of information and communication technology, the changing workforce configuration, and flexibility and new organizational practices are considered. As work has changed from physical to mental in nature, job characteristics have changed significantly. Meanwhile work and family life have blended. New systems of work organization have become more prevalent, but they do not represent a radical change across the whole economy. New practices may have an adverse impact upon job characteristics, but their effects depend on their design, implementation, and management. Research recommendations include improved monitoring of changes in work organization and studies into their health and safety consequences, intervention studies, studies into the motivating potential of modern work practices, studies of marginalized workers and workers in less developed countries, and "mechanism studies".

Purpose Although the role of return-to-work coordinators (RTW coordinators) is associated with reducing long-term disabilities, little has been written about their practices. The objective of this study was to clearly identify their tasks and activities and the stakeholders with whom they collaborate. Methods A cross-sectional survey was conducted using a web-based self-administered questionnaire. Participant inclusion criteria were as follows: (1) working for a large organization with 500 or more employees; (2) being responsible for managing disabilities and coordinating the return-to-work process; and (3) having been involved in coordinating the return to work of at least one person in the past year. Results 195 RTW coordinators completed the questionnaire. The three tasks or activities rated as most important were applying laws, policies, and regulations related to work absences and return to work; contacting the absent worker; and planning the return to work. A nursing or occupational health and safety training background significantly influenced the RTW coordinators' practices. In addition, RTW coordinators collaborated mainly with workers and their supervisors. Conclusion Despite a wide variety of contexts and diverging definitions of competencies, a set of common RTW coordination practices appears to exist across industrialized countries. RTW coordinators with a training background in the health field seem better able to assimilate the various dimensions of work disability. Moreover, concerted action was found to be minimal and a far cry from recommendations. The practices defined could serve as a benchmark for describing RTW coordinators' responsibilities in greater detail and allow for cross-organization and cross-country comparisons.

Analysis of Work Design in Rubber Processing Plant

The work design illustrates how structured jobs, tasks, and roles are defined and modified and their impact on individuals, groups, and organizations. If the work is not designed well, the company must pay greater costs for workers' health, longer production processes or even penalties for not being able to meet the delivery schedule. This is visible to the condition in a rubber processing factory in North Sumatra. Work design aspects such as layouts, machinery and equipment, worker's physical working environment, work methods, and organizational policies have not been well-organized. Coagulum grinding machines into sheets are often damaged, resulting in 4 times the delay of product delivery in 2016, the presence of complaints of heat exposure submitted by workers, and workstation that has not been properly arranged is an indication of the need for work design. The research data will be collected through field observation, and distribution of questionnaires related aspects of work design. The result of the analysis depends on the respondent's answer from the distributed questionnaire regarding the 6 aspects studied.

Work engagement in nursing: a concept analysis.

PubMed

Bargagliotti, L Antoinette

2012-06-01

  This article is a report of an analysis of the concept of work engagement. Background.  Work engagement is the central issue for 21st century professionals and specifically for registered nurses. Conceptual clarity about work engagement gives empirical direction for future research and a theoretical underpinning for the myriad studies about nurses and their work environment.   Walker and Avant's method of concept analysis was used. Nursing, business, psychology and health sciences databases were searched using Science Direct, CINAHL, OVID, Academic One File, ABI INFORM and PsycINFO for publications that were: written in English, published between 1990 and 2010, and described or studied work engagement in any setting with any population.   Work engagement is a positive, fulfilling state of mind about work that is characterized by vigour, dedication and absorption. Trust (organizationally, managerially and collegially) and autonomy are the antecedents of work engagement. The outcomes of nurses' work engagement are higher levels of personal initiative that are contagious, decreased hospital mortality rates and significantly higher financial profitability of organizations.   When work engagement is conceptually removed from a transactional job demands-resources model, the relational antecedents of trust and autonomy have greater explanatory power for work engagement in nurses. Untangling the antecedents, attributes and outcomes of work engagement is important to future research efforts. © 2011 Blackwell Publishing Ltd.

A concept analysis of 'Meaning in work' and its implications for nursing.

Lee, Soohee

2015-10-01

To report an analysis of the concept of 'meaning in work'. Associated with initiatives to improve the quality of working life and the emerging movement of positive organizations, 'meaning in work' has been studied as a positive individual-level state. 'Meaning in work' has potential benefits that will improve the nursing workforce if this concept is embraced in nursing. However, the concept is not clearly defined because it has been approached from diverse theoretical perspectives and used interchangeably with analogous terms. A concept analysis. Three key terms (using 'work', 'meaning' or 'meaningful', 'meaning of work', 'logotherapy') were searched in the CINAHL, PsycINFO, Business Source Complete and ABI/INFORM Global online databases from January 1940-March 2015. Among 346 articles retrieved, 28 studies were included for this concept analysis. The procedure of concept analysis developed by Walker and Avant (2011) was used. Four critical attributes are identified: (1) experienced positive emotion at work; (2) meaning from work itself; (3) meaningful purpose and goals of work; and (4) work as a part of life that contributes towards meaningful existence. The identified antecedent of 'meaning in work' was a cognitive shift and the identified consequences were positive personal experience and positive impact on peers and organizations. This article provides a clear definition of 'meaning in work'. The resulting coherent definition will facilitate the use of 'meaning in work' in nursing research. © 2015 John Wiley & Sons Ltd.

Mental health, constraints, and organization of work as interactive variables. A study of word processing secretaries.

PubMed

Billette, A; Carrier, M; Bernier, M; de Sève, M

1992-07-01

The effect of a work constraint is specific to the type of work organization. This article deals with the effects of different types of work organization on the mental health of secretaries. The advantage of choosing secretarial work as a research subject lies in the fact that we can identify three distinct types of work organization: (1) a secretary working directly for someone (the "paired" secretary-boss), (2) the "pool," geared toward keyboard input with no specific pairing of secretaries and authors, and (3) the departmental "team," a hybrid of the two preceding types, characterized by the presence of several secretaries, each one assigned to several authors. A study was conducted on the health problems reported by secretaries in the Québec civil service. Data available from a Santé Québec study, carried out at the same time, allowed us to constitute a general population reference group of secretaries and other working women. The findings indicate that secretaries in the general population are no more at risk than are other similar working women, but that secretaries in the provincial civil service are at risk. Regression analysis shows that the same traditional constraints do not affect secretaries in the same way regardless of whether they are members of pair, pool, or team organizations. This suggests that the context of work organization is an interactive or a "specifying variable" of the effect of work constraints on the secretaries' mental health.

Gender Regimes in Ontario Nursing Homes: Organization, Daily Work, and Bodies.

2017-06-01

Today more men work in the long-term care sector, but men are still in the minority. Little is known about men's experiences in care work, and the dilemmas and opportunities they face because of their gender. This article focuses on men care workers' integration into the organization and flow of nursing home work as perceived by these workers and staff members. Using a rapid ethnography method in two Ontario nursing homes, we found work organization affected interpretations of gender and race, and that workers' scope for discretion affected the integration and acceptance of men as care workers. In a nursing home with a rigid work organization and little worker discretion, women workers perceived men workers as a problem, whereas at a nursing home with a more flexible work organization that stressed relational care, both women and men workers perceived men workers as a resource in the organization.

Comprehensive workplace return-to-work policies, applied with consistency, can reduce length of time out of work and the risk of long-term disability. This paper reports on the findings from a qualitative study exploring managers' and return-to-work-coordinators' views on the implementation of their organization's new return-to-work program. To provide practical guidance to organizations in designing and implementing return-to-work programs for their employees. Semi-structured qualitative interviews were undertaken with 20 managers and 10 return-to-work co-ordinators to describe participants' perspectives on the progress of program implementation in the first 18 months of adoption. The study was based in a large healthcare organization in Ontario, Canada. Thematic analysis of the data was conducted. We identified tensions evident in the early implementation phase of the organization's return-to-work program. These tensions were attributed to uncertainties concerning roles and responsibilities and to circumstances where objectives or principles appeared to be in conflict. The implementation of a comprehensive and collaborative return-to-work program is a complex challenge. The findings described in this paper may provide helpful guidance for organizations embarking on the development and implementation of a return-to-work program.

Occupational stress of social workers is associated with various psychosocial hazards in the work environment. Some of them affect person-organization fit (P-O fit). The aim of the study was to verify a hypothesis on the mediating role of P-O fit in the relationship between work environment and stress. The research was based on a sample of 500 social workers directly involved in social work. The data were obtained using the Person-Organization Fit Questionnaire by Czarnota-Bojarska, the Work Environment Questionnaire developed by the Department of Occupational Psychology, Nofer Institute of Occupational Medicine, Łódź, and the Perceived Stress Scale (PSS-10) by Cohen et al. As revealed by the regression analysis of the 4 analyzed work environment factors, only organizational politics was significantly related with perceived stress. Complementary and supplementary dimensions of P-O fit and identification with organization were the mediators of the relationship between organizational policies and stress, but only complementary fit proved to be a total mediator. The results of the study suggest that person-organization fit, especially its complementary aspect, is an essential determinant of accomplishing the core functions of social work and good practice among social workers.

Quebec's health network has undertaken large-scale organizational changes to ensure the continuity, accessibility, and quality of health care and services for the population. This article describes the optimal approach for making changes to the organization of care and work for patients, health care workers, and organizations. This participative action research was carried out by means of interviews and document analysis. One hundred participants were involved, describing a total of 34 projects for significant organizational change. Results include an optimal approach broken down into 4 phases, each of which includes steps, facilitating factors, and potential difficulties. The phases of this approach are: (1) sharing the vision, mission, and values of the organization and identifying the purpose and need underlying the change; (2) building alliances and validating the involvement of the various players; (3) conceptualizing and planning the project; and (4) implementing changes and continuing evaluation. It is possible to rise to the challenge of finding new approaches to organize care and work by giving way to participation, mobilization, and innovation.

This analysis examines the associations of work organization attributes among Latino women in manual occupations with musculoskeletal and neurological injuries. Participants included 234 women in western North Carolina. Outcome measures included epicondylitis, rotator cuff syndrome, back pain, and carpal tunnel syndrome. Independent measures included indicators of job demand, job control, and job support, as well as personal characteristics. Latina workers commonly experienced epicondylitis, rotator cuff syndrome, back pain, and CTS. Awkward posture and decision latitude were associated with epicondylitis. Rotator cuff syndrome was associated with awkward posture and psychological demand. Awkward posture and psychological demand, and decreased skill variety and job control were related to CTS. Work organization factors are potentially important for musculoskeletal and neurological injury among vulnerable workers. Research is required to understand the associations of work and health outcomes of these women. Policy initiatives need to consider how work organization affects health. © 2014 Wiley Periodicals, Inc.

For the past decades, in a world of high competition, firms struggle to regain an advantage over foreign competition. Thus, new management trends, usually based on price reduction, high quality products and speed production are now part of strategic reorganization plans of high impact on work organization particularly in terms of large demands put on workers, and take a heavy toll on workers. Thus the incidence of mental health problems in the work place has risen sharply in recent years and currently counts as one of the leading causes of work absenteeism. A study based on the psychodynamic of work was conducted among machine operators working in a high-technology company in the aviation sector. Important management and technological transformations were recently introduced in the factory. The content analysis of the study shows that the work organization places the operator in a double bind situation. They are caught between an injunction where the capacity of making a high quality product is directly opposed to that demanding speed production. Moreover, severe and arbitrary sanctions are applied when the operators do not comply with either injunction. The operators are put in a deadlock situation that creates fear and anxiety. They are obliged to turn to defensive psychological strategies such as individualism and cheating. Those defensive strategies have negative impacts on social relationships.

Rethinking work-health models for the new global economy: a qualitative analysis of emerging dimensions of work.

PubMed

Polanyi, Michael; Tompa, Emile

2004-01-01

Technology change, rising international trade and investment, and increased competition are changing the organization, distribution and nature of work in industrialized countries. To enhance productivity, employers are striving to increase innovation while minimizing costs. This is leading to an intensification of work demands on core employees and the outsourcing or casualization of more marginal tasks, often to contingent workers. The two prevailing models of work and health - demand-control and effort-reward imbalance - may not capture the full range of experiences of workers in today's increasingly flexible and competitive economies. To explore this proposition, we conducted a secondary qualitative analysis of interviews with 120 American workers [6]. Our analysis identifies aspects of work affecting the quality of workers' experiences that are largely overlooked by popular work-health models: the nature of social interactions with customers and clients; workers' belief in, and perception of, the importance of the product of their work. We suggest that the quality of work experiences is partly determined by the objective characteristics of the work environment, but also by the fit of the work environment with the worker's needs, interests, desires and personality, something not adequately captured in current models.

Flattening the organization: implementing self-directed work groups.

PubMed

Brandon, G M

1996-01-01

In response to tremendous growth of managed care and threats to financial stability and job security, the Greater Baltimore Medical Center (GBMC) restructured itself into independent business units. The radiology department at GBMC resolved to reduce cost per unit-of-service, improve service, determine optimal staffing levels and reduce the number of layers of organization. It was decided to achieve those goals by implementing self-directed work groups. Staff buy-in was critical to success of the project. To begin, the staff was educated intensively about current trends in healthcare, managed care and potential changes in the job market. The radiology department was allowed to reduce the size of its staff through attrition and worked hard to focus staff concern on the impact each individual could have on the bottom line and the resultant effect on job security. Self-directed work groups were designed on a matrix that used small "service teams" in combinations to form larger "work groups." Actual work and daily activities occur at the service team level; information exchange and major decisions occue at the work group level. Seventeen months after beginning the project and 10 months after implementation, the organization has flattened, staff members have adjusted well to new roles, there have been no lay-offs, and the matrix system of small and large groups have proved particularly valuable.

2018-03-01

Objectives We sought to determine whether interventions that target work organization or the psychosocial work environment are effective in preventing or reducing work-related musculoskeletal disorders (WMSD) compared to usual work. Methods We systematically reviewed the 2000-2015 English- and French-language scientific literature, including studies evaluating the effectiveness of an organizational or psychosocial work intervention on incidence, prevalence or intensity of work-related musculoskeletal pain or disorders in the neck, shoulders, upper limbs and/or back or of work absence due to such problems, among non-sick-listed workers. We excluded rehabilitation and individual-level behavioral interventions and studies with >50% attrition. We analyzed medium- and high-quality studies and synthesized the evidence using the Grading of Recommendations Assessment, Development & Evaluation (GRADE) approach. An analysis of key workplace intervention elements supplemented the interpretation of results. Results We identified 884 articles; 28 met selection criteria, yielding 2 high-quality, 10 medium-quality and 16 low-quality studies. There was moderate evidence that supplementary breaks, compared to conventional break schedules, are effective in reducing symptom intensity in various body regions. Evidence was low-to-very-low quality for other interventions, primarily due to risk of bias related to study design, high attrition rates, co-interventions, and insensitive indicators. Most interventions lacked key intervention elements, such as work activity analysis and ergonomist guidance during implementation, but the relation of these elements to intervention effectiveness or ineffectiveness remains to be demonstrated. Conclusions Targeting work-rest cycles may reduce WMSD. Better quality studies are needed to allow definitive conclusions to be drawn on the effectiveness of other work organizational or psychosocial interventions to prevent or reduce WMSD.

The family interview context is permeated by numerous ethical issues which may generate conflicts and impact on organ donation process. This study aims to analyze the family interview process with a focus on principlist bioethics. This exploratory, descriptive study uses a qualitative approach. The speeches were collected using the following prompt: "Talk about the family interview for the donation of organs and tissues for transplantation, from the preparation for the interview to the decision of the family to donate or not." For the treatment of qualitative data, we chose the method of content analysis and categorical thematic analysis. The study involved 18 nurses who worked in three municipal organ procurement organizations in São Paulo, Brazil, and who conducted family interviews for organ donation. Ethical considerations: The data were collected after approval of the study by the Research Ethics Committee of the School of Nursing of the University of São Paulo. The results were classified into four categories and three subcategories. The categories are the principles adopted by principlist bioethics. The principles of autonomy, beneficence, non-maleficence, and justice permeate the family interview and reveal their importance in the organs and tissues donation process for transplantation. The analysis of family interviews for the donation of organs and tissues for transplantation with a focus on principlist bioethics indicates that the process involves many ethical considerations. The elucidation of these aspects contributes to the discussion, training, and improvement of professionals, whether nurses or not, who work in organ procurement organizations and can improve the curriculum of existing training programs for transplant coordinators who pursue ethics in donation and transplantation as their foundation.

Emergency response organizations need to be resilient to cope with escalating events resulting from dynamic, unexpected, or complex situations. In Brazil, the Firefighter Corps are military hierarchal organizations with a culture based on fixed structures, well defined norms and procedures. These push against innovations which are necessary to be resilient. This research describes how firefighter captains in the 30-35-year age range managed an emergency response escalation in light of standard operating procedures (SOPs) during a training exercise. The study used ethnographic methods to find and discuss gaps between the instructions and the activities carried out during the exercise, highlighting the differences between work as done (WAD) and work as imagined (WAI), as it was instantiated in the SOP prescriptions. The aim was to produce reflections on WAI and WAD as a way to raise awareness of the need for a cultural change toward resilience in firefighter organizations. This was achieved through firefighter engagement with a comprehensive visualization of the analysis results which afforded easy interaction between the experts, the data, and the researchers.

2016-01-01

BACKGROUND: Comprehensive workplace return-to-work policies, applied with consistency, can reduce length of time out of work and the risk of long-term disability. This paper reports on the findings from a qualitative study exploring managers’ and return-to-work-coordinators’ views on the implementation of their organization’s new return-to-work program. OBJECTIVES: To provide practical guidance to organizations in designing and implementing return-to-work programs for their employees. METHODS: Semi-structured qualitative interviews were undertaken with 20 managers and 10 return-to-work co-ordinators to describe participants’ perspectives on the progress of program implementation in the first 18 months of adoption. The study was based in a large healthcare organization in Ontario, Canada. Thematic analysis of the data was conducted. RESULTS: We identified tensions evident in the early implementation phase of the organization’s return-to-work program. These tensions were attributed to uncertainties concerning roles and responsibilities and to circumstances where objectives or principles appeared to be in conflict. CONCLUSIONS: The implementation of a comprehensive and collaborative return-to-work program is a complex challenge. The findings described in this paper may provide helpful guidance for organizations embarking on the development and implementation of a return-to-work program. PMID:27792035

WORKPLACE SOCIAL SUPPORT AND WORK-FAMILY CONFLICT: A META-ANALYSIS CLARIFYING THE INFLUENCE OF GENERAL AND WORK-FAMILY-SPECIFIC SUPERVISOR AND ORGANIZATIONAL SUPPORT.

This article uses meta-analysis to develop a model integrating research on relationships between employee perceptions of general and work-family-specific supervisor and organizational support and work-family conflict. Drawing on 115 samples from 85 studies comprising 72,507 employees, we compared the relative influence of 4 types of workplace social support to work-family conflict: perceived organizational support (POS); supervisor support; perceived organizational work-family support, also known as family-supportive organizational perceptions (FSOP); and supervisor work-family support. Results show work-family-specific constructs of supervisor support and organization support are more strongly related to work-family conflict than general supervisor support and organization support, respectively. We then test a mediation model assessing the effects of all measures at once and show positive perceptions of general and work-family-specific supervisor indirectly relate to work-family conflict via organizational work-family support. These results demonstrate that work-family-specific support plays a central role in individuals' work-family conflict experiences.

An analysis of the implementation of PEPFAR's anti-prostitution pledge and its implications for successful HIV prevention among organizations working with sex workers.

Since 2003, US government funding to address the HIV and AIDS pandemic has been subject to an anti-prostitution clause. Simultaneously, the efficacy of some HIV prevention efforts for sex work in areas receiving US government funding has diminished. This article seeks to explain why. This analysis utilizes a case story approach to build a narrative of defining features of organizations in receipt of funding from the President's Emergency Plan for AIDS Relief (PEPFAR) and other US funding sources. For this analysis, multiple cases were compiled within a single narrative. This helps show restrictions imposed by the anti-prostitution clause, any lack of clarity of guidelines for implementation and ways some agencies, decision-making personnel, and staff on the ground contend with these restrictions. Responses to PEPFAR's anti-prostitution clause vary widely and have varied over time. Organizational responses have included ending services for sex workers, gradual phase-out of services, cessation of seeking US government HIV funds and increasing isolation of sex workers. Guidance issued in 2010 did not clarify what was permitted. Implementation and enforcement has been dependent in part on the interpretations of this policy by individuals, including US government representatives and organizational staff. Different interpretations of the anti-prostitution clause have led to variations in programming, affecting the effectiveness of work with sex workers. The case story approach proved ideal for working with information like this that is highly sensitive and vulnerable to breach of anonymity because the method limits the potential to betray confidences and sources, and limits the potential to jeopardize funding and thereby jeopardize programming. This method enabled us to use specific examples without jeopardizing the organizations and individuals involved while demonstrating unintended consequences of PEPFAR's anti-prostitution pledge in its provision of services to sex

Laser-launched flyers with organic working fluids

Mulford, Roberta; Swift, Damian

2003-10-01

The TRIDENT laser has been used to launch flyers by depositing IR energy in a thin layer of material - the working fluid - sandwiched between the flyer and a transparent substrate. We have investigated the use of working fluids based on organics, chosen as they are quite efficient absorbers of IR energy and should also convert heat to mechanical work more efficiently than materials such as carbon. A thermodynamically complete equation of state was developed for one of the fluids investigated experimentally - a carbohydrate solution - by chemical equilibrium calculations using the CHEETAH program. Continuum mechanics simulations were made of the flyer launch process, modeling the effect of the laser as energy deposition in the working fluid, and taking into account the compression and recoil of the substrate. We compare the simulations with a range of experiments and demonstrate the optimization of substrate and fluid thickness for a given flyer thickness and speed.

Promotor(a)s, the organizations in which they work, and an emerging paradox: how organizational structure and scope impact promotor(a)s' work.

May, Marlynn L; Contreras, Ricardo B

To analyze how organizational structures and scope (geographic and programmatic) generate dissonance between the organization and its workers, creating a paradox with policy implications for access to health care in hard-to-reach populations. The workers are lay community health workers called promotor(a)s. The organizations are community based organizations in which the promotor(a)s work, either as volunteers, part-time or as full-time wage staff. Ethnographic study of 12 organizations and their promotor(a)s. Data gathering included interviews with organization directors, promotor(a)s, service providers working with the organizations, and community residents served by the organizations and workers. In addition, promotor(a)s were observed in the course of their work. Sampling was a non-probability, snowball procedure for identifying the organizations and the workers within them. A paradox is emerging between (a) promotor(a)s who perceive their work to be locally focused and tightly integrated with the communities they serve and live in, and (b) the employing organizations that are expanding in geographical and programmatic scope because the work promotor(a)s do is in increasing demand by agencies and funding sources external to the communities served. The paradox potentially threatens to undermine and transform the work and working environment of the promotor(a)s. The challenge is to find a balance that will sustain a workable and working relationship among the organization, the workers, and the communities served. Care is needed in setting out policies that translate the paradox into greater congruence among organization, workers and communities. Policy needs discussed focus on (a) worker training, (b) worker employment and deployment, and (c) funding source recognition of the paradox.

1997-01-01

For 25 years, the National Institute for Occupational Safety and Health (NIOSH) has conducted and sponsored laboratory, field, and epidemiological studies that have helped define the role of work organization factors in occupational safety and health. Research has focused on the health effects of specific job conditions, occupational stressors in specific occupations, occupational difference in the incidence of stressors and stress-related disorders, and intervention strategies. NIOSH and the American Psychological Association have formalized the concept of occupational health psychology and developed a postdoctoral training program. The National Occupational Research Agenda recognizes organization of work as one of 21 national occupational safety and health research priority areas. Future research should focus on industries, occupations, and populations at special risk; the impact of work organization on overall health; the identification of healthy organization characteristics; and the development of intervention strategies.

Purpose To better understand the environmental constraints on nurse managers that impact their need for and use of decision support tools, we conducted a Cognitive Work Analysis (CWA). A complete CWA includes system analyses at five levels: work domain, decision-making procedures, decision-making strategies, social organization/collaboration, and worker skill level. Here we describe the results of the Work Domain Analysis (WDA) portion in detail then integrate the WDA with other portions of the CWA, reported previously, to generate a more complete picture of the nurse manager’s work domain. Methods Data for the WDA were obtained from semi-structured interviews with nurse managers, division directors, CNOs, and other managers (n = 20) on 10 patient care units in 3 Arizona hospitals. The WDA described the nurse manager’s environment in terms of the constraints it imposes on the nurse manager’s ability to achieve targeted outcomes through organizational goals and priorities, functions, processes, as well as work objects and resources (e.g., people, equipment, technology, and data). Constraints were identified and summarized through qualitative thematic analysis. Results The results highlight the competing priorities, and external and internal constraints that today’s nurse managers must satisfy as they try to improve quality and safety outcomes on their units. Nurse managers receive a great deal of data, much in electronic format. Although dashboards were perceived as helpful because they integrated some data elements, no decision support tools were available to help nurse managers with planning or answering “what if” questions. The results suggest both the need for additional decision support to manage the growing complexity of the environment, and the constraints the environment places on the design of that technology if it is to be effective. Limitations of the study include the small homogenous sample and the reliance on interview data targeting safety

Staff nurse commitment, work relationships, and turnover intentions: a latent profile analysis.

Gellatly, Ian R; Cowden, Tracy L; Cummings, Greta G

2014-01-01

The three-component model of organization commitment has typically been studied using a variable-centered rather than a person-centered approach, preventing a more complete understanding of how these forms of commitment are felt and expressed as a whole. Latent profile analysis was used to identify qualitatively distinct categories or profiles of staff nurses' commitment. Then, associations of the profiles with perceived work unit relations and turnover intentions were examined. Three hundred thirty-six registered nurses provided data on affective, normative, and continuance commitment, perceived work unit relations, and turnover intentions. Latent profile analysis of the nurses' commitment scores revealed six distinct profile groups. Work unit relations and turnover intentions were compared in the six profile-defined groups. Staff nurses with profiles characterized by high affective commitment and/or high normative commitment in relation to other components experienced stronger work unit relations and reported lower turnover intentions. Profiles characterized by high continuance commitment relative to other components or by low overall commitment experienced poorer work unit relations, and the turnover risk was higher. High continuance commitment in combination with high affective and normative commitment was experienced differently than high continuance commitment in combination with low affective and normative commitment. Healthcare organizations often foster commitment by using continuance commitment-enhancing strategies (e.g., offer high salaries and attractive benefits) that may inadvertently introduce behavioral risk. This work suggests the importance of changing the context in which continuance commitment occurs by strengthening the other two components.

Rates of occupational injury among immigrant workers are widely believed to be underestimated. The goal of this study was to enhance understanding of the burden of occupational injury and the work organization factors underlying injury among immigrant Latino residential construction workers. Prospective data were obtained from a community-based sample of Latino residential construction workers (N = 107) over a 3-month period. Twenty-eight participants were injured, resulting in an injury incidence rate of 55.0/100 FTE (95% CI = 41.4-71.6) during the 3-month observation period. The injury rate involving days away from work during the observation period was 3.9/100 FTE (CI = 0.2-7.2). Injuries were elevated among roofers relative to framers and general construction workers. Roofers had elevated exposure to a variety of deleterious work organization factors. Although imprecise given the small sample, our results suggest a threefold to fourfold underestimate of the injury burden to immigrant Latino construction workers. Work organization may contribute to elevated rates of non-fatal occupational injury, particularly among roofers. Copyright © 2012 Wiley Periodicals, Inc.

2009-01-01

The purpose of this article was to describe key elements of an inpatient medication system using the cognitive work analysis method of Rasmussen et al (Cognitive Systems Engineering. Wiley Series in Systems Engineering; 1994). The work of nurses and physicians were observed in routine care of inpatients on a medical-surgical unit and attached ICU. Interaction with pharmacists was included. Preoperative, postoperative, and medical care was observed. Personnel were interviewed to obtain information not easily observable during routine work. Communication between healthcare workers was projected onto an abstraction/decomposition hierarchy. Decision ladders and information flow charts were developed. Results suggest that decision making on an inpatient medical/surgical unit or ICU setting is a parallel, distributed process. Personnel are highly mobile and often are working on multiple issues concurrently. In this setting, communication is key to maintaining organization and synchronization for effective care. Implications for research approaches to system and interface designs and decision support for personnel involved in the process are discussed.

Although biometric attendance management is available, large healthcare organizations have difficulty in big data analysis for optimization of work processes. The aim of this project was to assess the implementation of a biometric attendance system and its utility following big data analysis. In this prospective study the implementation of biometric system was evaluated over 3 month period at our institution. Software integration with other existing systems for data analysis was also evaluated. Implementation of the biometric system could be successfully done over a two month period with enrollment of 10,000 employees into the system. However generating reports and taking action this large number of staff was a challenge. For this purpose software was made for capturing the duty roster of each employee and integrating it with the biometric system and adding an SMS gateway. This helped in automating the process of sending SMSs to each employee who had not signed in. Standalone biometric systems have limited functionality in large organizations unless it is meshed with employee duty roster.

Self-defeating behaviors in organizations: the relationship between thwarted belonging and interpersonal work behaviors.

2007-05-01

This multisource field study applied belongingness theory to examine whether thwarted belonging, defined as the perceived discrepancy between one's desired and actual levels of belonging with respect to one's coworkers, predicts interpersonal work behaviors that are self-defeating. Controlling for demographic variables, job type, justice constructs, and trust in organization in a multilevel regression analysis using data from 130 employees of a clinical chemical laboratory and their supervisors, the authors found that employees who perceive greater levels of desired coworker belonging than actual levels of coworker belonging were more likely to engage in interpersonally harmful and less likely to engage in interpersonally helpful behaviors. Implications for the application of belongingness theory to explain self-defeating behaviors in organizations are discussed. 2007 APA, all rights reserved

The NASA Space Science Support Network Community-based Organizations Working Group (CBOWG) has been working for the past two years on issues surrounding afterschool programs and programs for youth (e.g., Girl Scouts, Boy Scouts, Boys and Girls Clubs, 4-H, summer camps, afterschool and weekend programs for various ages, programs with emphases on minority youth). In this session the co-leaders of the CBOWG will discuss the challenges of working with community-based organizations on a regional or national level. We will highlight some ties that we have forged with the National Institute for Out of School Time (NIOST) and the National Afterschool Association (NAA). We will also talk about efforts to coordinate how various entities within NASA cooperate with community-based organizations to serve the best interests of these groups. We will give a couple of examples of how NASA space science organizations have partnered with community-based organizations. The session will include some handouts of information and resources that the CBOWG has found useful in developing an understanding of this segment of informal education groups. We would like to thank NASA for providing resources to support the work of the CBOWG.

Improving social connection through a communities-of-practice-inspired cognitive work analysis approach.

Increasingly, people work in socially networked environments. With growing adoption of enterprise social network technologies, supporting effective social community is becoming an important factor in organizational success. Relatively few human factors methods have been applied to social connection in communities. Although team methods provide a contribution, they do not suit design for communities. Wenger's community of practice concept, combined with cognitive work analysis, provided one way of designing for community. We used a cognitive work analysis approach modified with principles for supporting communities of practice to generate a new website design. Over several months, the community using the site was studied to examine their degree of social connectedness and communication levels. Social network analysis and communications analysis, conducted at three different intervals, showed increases in connections between people and between people and organizations, as well as increased communication following the launch of the new design. In this work, we suggest that human factors approaches can be effective in social environments, when applied considering social community principles. This work has implications for the development of new human factors methods as well as the design of interfaces for sociotechnical systems that have community building requirements.

2005-01-01

Background This article describes the validation of an instrument to measure work group climate in public health organizations in developing countries. The instrument, the Work Group Climate Assessment Tool (WCA), was applied in Brazil, Mozambique, and Guinea to assess the intermediate outcomes of a program to develop leadership for performance improvement. Data were collected from 305 individuals in 42 work groups, who completed a self-administered questionnaire. Methods The WCA was initially validated using Cronbach's alpha reliability coefficient and exploratory factor analysis. This article presents the results of a second validation study to refine the initial analyses to account for nested data, to provide item-level psychometrics, and to establish construct validity. Analyses included eigenvalue decomposition analysis, confirmatory factor analysis, and validity and reliability analyses. Results This study confirmed the validity and reliability of the WCA across work groups with different demographic characteristics (gender, education, management level, and geographical location). The study showed that there is agreement between the theoretical construct of work climate and the items in the WCA tool across different populations. The WCA captures a single perception of climate rather than individual sub-scales of clarity, support, and challenge. Conclusion The WCA is useful for comparing the climates of different work groups, tracking the changes in climate in a single work group over time, or examining differences among individuals' perceptions of their work group climate. Application of the WCA before and after a leadership development process can help work groups hold a discussion about current climate and select a target for improvement. The WCA provides work groups with a tool to take ownership of their own group climate through a process that is simple and objective and that protects individual confidentiality. PMID:16223447

Recipient-related factors, such as education level and type of health insurance, are known to affect heart transplantation outcomes. Pre-operative employment status has shown an association with survival in abdominal organ transplant patients. We sought to evaluate the effect of work status of heart transplant (HTx) recipients at the time of listing and at the time of transplantation on short- and long-term survival. We evaluated the United Network for Organ Sharing (UNOS) registry for all adult HTx recipients from 2001 to 2014. Recipients were grouped based on their work status at listing and at heart transplantation. Kaplan-Meier estimates illustrated 30-day, 1-year, 5-year, and 10-year survival comparing working with non-working groups. The Cox proportional hazards regression model was applied to adjust for covariates that could potentially confound the post-transplantation survival analysis. Working at listing for HTx was not significantly associated with 30-day and 1-year survival. However, 5- and 10-year mortality were 14.5% working vs 19.8% not working (p < 0.0001) and 16% working vs 26% not working (p < 0.0001), respectively. Working at HTx appeared to be associated with a survival benefit at every time interval, with a trend toward improved survival at 30 days and 1 year and a significant association at 5 and 10 years. Kaplan-Meier analysis demonstrated a 5% and 10% decrease in 5- and 10-year mortality, respectively, for the working group compared with the group not working at transplantation. The Cox proportional hazards regression model showed that working at listing and working at transplantation were each associated with decreased mortality (hazard ratio [HR] = 0.8, 95% confidence interval [CI] 0.71 to 0.91; and HR = 0.76, 95% CI 0.65 to 0.89, respectively). This study is the first analysis of UNOS STAR data on recipient work status pre-HTx demonstrating: (1) an improvement in post-transplant survival for working HTx candidates; and (2

Global labour markets continue to undergo significant transformations resulting from socio-political instability combined with rises in structural inequality, employment insecurity, and poor working conditions. Confronted by these challenges, global institutions are providing policy guidance to protect and promote the health and well-being of workers. This article provides an account of how the International Labour Organization's Decent Work Agenda contributes to the work policy agendas of the World Health Organization and the World Bank. This qualitative study involved semi-structured interviews with representatives from three global institutions--the International Labour Organization (ILO), the World Health Organization and the World Bank. Of the 25 key informants invited to participate, 16 took part in the study. Analysis for key themes was followed by interpretation using selected agenda setting theories. Interviews indicated that through the Decent Work Agenda, the International Labour Organization is shaping the global policy narrative about work among UN agencies, and that the pursuit of decent work and the Agenda were perceived as important goals with the potential to promote just policies. The Agenda was closely linked to the World Health Organization's conception of health as a human right. However, decent work was consistently identified by World Bank informants as ILO terminology in contrast to terms such as job creation and job access. The limited evidence base and its conceptual nature were offered as partial explanations for why the Agenda has yet to fully influence other global institutions. Catalytic events such as the economic crisis were identified as creating the enabling conditions to influence global work policy agendas. Our evidence aids our understanding of how an issue like decent work enters and stays on the policy agendas of global institutions, using the Decent Work Agenda as an illustrative example.

In this study, we aimed at exploring the association between work-related musculoskeletal disorders (WMSDs) and work organization based on a case-control study. A total of 1938 workers who claimed to suffer from WMSDs were selected from Beijing, Henan, Hubei, and the Guangdong province. The control group consisted of 2009 workers employed in similar industries without severe disease or musculoskeletal discomforts. We used a modified version of the questionnaire developed by the NMQ and the DMQ to investigate individual and work-related factors. A total of 13 variables (P<0.1) were selected by the chi-square test and finally, 7 variables entered into the equation, with 6 variables reaching statistical significance (P<0.05). The odds ratios (OR) of 'work changing with season' and 'sufficient rest time' did not reach 1 (0.749 and 0.441, respectively). In addition, 'sufficient rest time' seemed to be the stronger protective factor according to its higher standardized coefficient. And 'repetitive work every minute', 'constantly repetitive work' (every day), 'shortage of site personnel', and 'often switching shifts with others' seemed to be the risk factors. Work organization may have comprehensive effects on the occurrence of WMSDs. This pattern of associations suggests that further investigation into the mechanism of how work organization affects the prevalence of WMSDs is required.

It has long been recognized that a suite of proteins exists in coral skeletons that is critical for the oriented precipitation of calcium carbonate crystals, yet these proteins remain poorly characterized. Using liquid chromatography-tandem mass spectrometry analysis of proteins extracted from the cell-free skeleton of the hermatypic coral, Stylophora pistillata, combined with a draft genome assembly from the cnidarian host cells of the same species, we identified 36 coral skeletal organic matrix proteins. The proteome of the coral skeleton contains an assemblage of adhesion and structural proteins as well as two highly acidic proteins that may constitute a unique coral skeletal organic matrix protein subfamily. We compared the 36 skeletal organic matrix protein sequences to genome and transcriptome data from three other corals, three additional invertebrates, one vertebrate, and three single-celled organisms. This work represents a unique extensive proteomic analysis of biomineralization-related proteins in corals from which we identify a biomineralization “toolkit,” an organic scaffold upon which aragonite crystals can be deposited in specific orientations to form a phenotypically identifiable structure.

Understanding Values in a Large Health Care Organization through Work-Life Narratives of High-Performing Employees

PubMed Central

Karnieli-Miller, Orit; Taylor, Amanda C.; Inui, Thomas S.; Ivy, Steven S.; Frankel, Richard M.

2011-01-01

Objective— To understand high-performing frontline employees’ values as reflected in their narratives of day-to-day interactions in a large health care organization. Methods— A total of 150 employees representing various roles within the organization were interviewed and asked to share work-life narratives (WLNs) about value-affirming situations (i.e. situations in which they believed their actions to be fully aligned with their values) and value-challenging situations (i.e. when their actions or the actions of others were not consistent with their values), using methods based on appreciative inquiry. Results— The analysis revealed 10 broad values. Most of the value-affirming WLNs were about the story-teller and team providing care for the patient/family. Half of the value-challenging WLNs were about the story-teller or a patient and barriers created by the organization, supervisor, or physician. Almost half of these focused on “treating others with disrespect/respect”. Only 15% of the value-challenging WLNs contained a resolution reached by the participants, often leaving them describing unresolved and frequently negative feelings. Conclusions— Appreciative inquiry and thematic analysis methods were found to be an effective tool for understanding the important and sometimes competing role personal and institutional values play in day-to-day work. There is remarkable potential in using WLNs as a way to surface and reinforce shared values and, perhaps more importantly, respectfully to identify and discuss conflicting personal and professional values.

This qualitative study explored common and divergent perceptions of caregivers and managers regarding occupational health and safety, work organization, and psychosocial concerns in long-term care centers. Both common and differing issues were identified. Both groups agreed on the importance of ergonomic concerns, the high prevalence of stress, and receptiveness to participatory health promotion programs. However, numerous work organization issues and physical and psychosocial workplace hazards were identified by certified nursing assistants but were not mentioned by managers. The results suggest that different perceptions naturally arise from people's varying positions in the occupational hierarchy and their consequent exposures to health and safety hazards. Improved systems of communication that allow frontline workers to express their concerns would make it possible to create solutions to these problems. PMID:21261239

Mobbing is a phenomenon produced for the most part by factors related to work organization. During the medical control of workers in Universitary Policlinico Hospital of Palermo, we used a methodology (in advance applied with effectiveness by ISPESL in other institutions) that is able to evidence factors of work organization causing Mobbing. 338 out 2060 workers (total staff) with different professional figures were recruited. We evidenced the working classes that had more troubles about communications of business information, about interpersonal relationships at work with top manager, with other members of team and with colleagues. Particularly doctors and OTA, in worrying percentage, stated that they suffered psychological molestations. Aim of our study was to assay a procedure that, even if it doesn't identify proclaimed mobbing phenomenon, enables us to acquire information about relationships between business management and workers and organizational aspects perceiving by subordinates. A I level study about a phenomenon in expansion is very useful to recognize preventively intentionally made mobbing actions.

We sought to describe work organization attributes for employed immigrant Latinas and determine associations of work organization with physical health, mental health, and health-related quality of life. We conducted a cross-sectional survey with 319 employed Latinas in western North Carolina (2009-2011). Measures included job demands (heavy load, awkward posture, psychological demand), decision latitude (skill variety, job control), support (supervisor control, safety climate), musculoskeletal symptoms, mental health (depressive symptoms), and mental (MCS) and physical component score (PCS) health-related quality of life. Three fifths reported musculoskeletal symptoms. Mean scores for depression, MCS, and PCS were 6.2 (SE = 0.2), 38.3 (SE = 0.5), and 42.8 (SE = 0.3), respectively. Greater job demands (heavy load, awkward posture, greater psychological demand) were associated with more musculoskeletal and depressive symptoms and worse MCS. Less decision latitude (lower skill variety, job control) was associated with more musculoskeletal and depressive symptoms. Greater support (supervisor's power and safety climate) was associated with fewer depressive symptoms and better MCS. Work organization should be considered to improve occupational health of vulnerable women workers. Additional research should delineate the links between work organization and health among vulnerable workers.

Ibañez, Gabriela A.; Escandar, Graciela M.

2011-01-01

The development of chemical sensors for environmental analysis based on fluorescence, phosphorescence and chemiluminescence signals continues to be a dynamic topic within the sensor field. This review covers the fundamentals of this type of sensors, and an update on recent works devoted to quantifying organic pollutants in environmental waters, focusing on advances since about 2005. Among the wide variety of these contaminants, special attention has been paid polycyclic aromatic hydrocarbons, pesticides, explosives and emerging organic pollutants. The potential of coupling optical sensors with multivariate calibration methods in order to improve the selectivity is also discussed. PMID:22247654

Explicit processing demands reveal language modality-specific organization of working memory.

PubMed

Rudner, Mary; Rönnberg, Jerker

2008-01-01

The working memory model for Ease of Language Understanding (ELU) predicts that processing differences between language modalities emerge when cognitive demands are explicit. This prediction was tested in three working memory experiments with participants who were Deaf Signers (DS), Hearing Signers (HS), or Hearing Nonsigners (HN). Easily nameable pictures were used as stimuli to avoid confounds relating to sensory modality. Performance was largely similar for DS, HS, and HN, suggesting that previously identified intermodal differences may be due to differences in retention of sensory information. When explicit processing demands were high, differences emerged between DS and HN, suggesting that although working memory storage in both groups is sensitive to temporal organization, retrieval is not sensitive to temporal organization in DS. A general effect of semantic similarity was also found. These findings are discussed in relation to the ELU model.

In situ search for organics by gas chromatography analysis: new derivatization / thermochemolysis approach

NASA Astrophysics Data System (ADS)

Geffroy, Claude; Buch, Arnaud; David, Marc; Aissat, Lyes; El Mufleh, Amel; Papot, S.; Sternberg, Robert

Many organic molecules are present in interstellar clouds and might be carried to the early Earth by comets and meteorites during the heavy bombardment phase in the first few hundred million years of the solar system. It has been suggested that extraterrestrial organic material may well represent an important part of the organic material available for the origin of life. Until samples, brought by future space missions, are available on Earth, in situ measurements are one of the way to get unaltered and non-contaminated samples for analysis. The analytical technique has to be robust, sensitive and non-specific due to the large scope of targets molecules. The only currently flight qualified technique of analysis of organic molecules in space is gas chromatography (Viking, Cassini-Huygens, SAM-MSL, COSAC-Rosetta). The main objective of this work is to present a new approach with multi step analysis using derivatisation and thermochemolysis reagents for a one pot in situ analysis of volatile and refractory organics in surface or sub-surface samples (Mars, comets).Indeed, no single technology enables to identify all organic compounds because naturally occurring molecules have different polarities, molecular weights, being extractible or recalcitrant, bonded trapped or adsorbed on minerals. Thus, we propose to wider the scope of chemical reagent already validated for in situ wet chemistry such as MTBSTFA (Rodier et al. 2001, 2002), DMF-DMA (Rodier et al. 2002), or TMAH (Rodier et al, 2005, Geffroy-Rodier et al; 2009) to analyze enantiomers of amino acids, carbohydrates and lipids in a one pot several steps sub system using a multi reagent and multi step approach. Thus using a new derivatizing agent, we successfully identified twenty one amino acids including twelve of the twenty proteinic amino acids without inhibiting following multi step thermochemolysis. *Geffroy-Rodier C, Grasset L, Sternberg R.

Swanberg, Jennifer E; Clouser, Jess Miller; Westneat, Susan

2012-08-01

Agriculture is hazardous and increasingly dependent on Latino workers, a vulnerable population. However, little research has studied how work organization influences Latino farmworker health. Using a work organization framework, this cross-sectional study describes and compares the work organization and occupational health characteristics of a sample of Latino crop (n = 49) and horse production (n = 54) workers in Kentucky. Crop workers experienced more physical demands, work-related and environmental stressors, and musculoskeletal and ill-health symptoms. Significantly more crop workers indicated work-related illness or missed work due to work-related illness/injury, though one-fourth of both groups reported work-related injury in the past year. A majority of both groups cited exposure to toxic chemicals, a minority of whom received training on their use. Further surveillance is needed to understand the rate and precursors of illness/injury in these populations, as is research on the relationship between supervisory practices, psychosocial stressors, and occupational health.

The importance of work organization on workload and musculoskeletal health--Grocery store work as a model.

PubMed

Balogh, I; Ohlsson, K; Nordander, C; Björk, J; Hansson, G-Å

2016-03-01

We have evaluated the consequences of work organization on musculoskeletal health. Using a postal questionnaire, answered by 1600 female grocery store workers, their main work tasks were identified and four work groups were defined (cashier, picking, and delicatessen work, and a mixed group, who performed a mix of these tasks). The crude odds ratios (ORs) for neck/shoulder complaints were 1.5 (95% CI 1.0-2.2), 1.1 (0.7-1.5) and 1.6 (1.1-2.3), respectively, compared to mixed work. Adjusting for individual and psychosocial factors had no effect on these ORs. For elbows/hands, no significant differences were found. Technical measurements of the workload showed large differences between the work groups. Picking work was the most strenuous, while cashier work showed low loads. Quantitative measures of variation revealed for mixed work high between minutes variation and the highest between/within minutes variation. Combining work tasks with different physical exposure levels increases the variation and may reduce the risk of musculoskeletal complaints. Copyright © 2015 Elsevier Ltd and The Ergonomics Society.

2013-01-01

Studies across industries suggest that the systematic use of high-performance work practices (HPWPs) may be an effective but underused strategy to improve quality of care in healthcare organizations. Optimal use of HPWPs depends on how they are implemented, yet we know little about their implementation in healthcare. We conducted 67 key informant interviews in five healthcare organizations, each considered to have exemplary work practices in place and to deliver high-quality care, as part of an extensive study of HPWP use in healthcare. We analyzed interview transcripts inductively and deductively to examine why and how organizations implement HPWPs. We used an evidence-based model of complex innovation adoption to guide our exploration of factors that facilitate HPWP implementation. We found considerable variability in interviewees' reasons for implementing HPWPs, including macro-organizational (strategic level) and micro-organizational (individual level) reasons. This variability highlighted the complex context for HPWP implementation in many organizations. We also found that our application of an innovation implementation model helped clarify and categorize facilitators of HPWP implementation, thus providing insight on how these factors can contribute to implementation effectiveness. Focusing efforts on clarifying definitions, building commitment, and ensuring consistency in the application of work practices may be particularly important elements of successful implementation.

Social Consequences of Nomadic Working: A Case Study in an Organization

NASA Astrophysics Data System (ADS)

Singh, Ramanjit; Wood-Harper, Trevor

This research study identified social challenges that knowledge workers in the Swedish organization TeliaSonera (Telia) face when utilizing wireless technologies to conduct work on the move. Upon collecting the relevant research data, five problem areas were identified: work and life balance, addiction, organizational involvement, nomadic work and control, and individual productivity. Each problem area was examined with the philosophical underpinning of socio-technical design principles. The results confirm that better role boundary management, self-discipline, work negotiation, and e-mail communication skills may be required for the knowledge workers to manage the demands of nomadic working. Similarly, rewarding nomadic work performance, building employee supervisor trust relations, and designing jobs that enhance work and life balance can be imperative.

Changing Workplaces to Reduce Work-Family Conflict: Schedule Control in a White-Collar Organization

2011-01-01

Work-family conflicts are common and consequential for employees, their families, and work organizations. Can workplaces be changed to reduce work-family conflict? Previous research has not been able to assess whether workplace policies or initiatives succeed in reducing work-family conflict or increasing work-family fit. Using longitudinal data collected from 608 employees of a white-collar organization before and after a workplace initiative was implemented, we investigate whether the initiative affects work-family conflict and fit, whether schedule control mediates these effects, and whether work demands, including long hours, moderate the initiative’s effects on work-family outcomes. Analyses clearly demonstrate that the workplace initiative positively affects the work-family interface, primarily by increasing employees’ schedule control. This study points to the importance of schedule control for our understanding of job quality and for management policies and practices. PMID:21580799

The study assessed the association between well-being, work-environment and employees? health among the personnel in savings- and other banks? branches with reference to whether they had been exposed to bullying at work. A questionnaire based on the General Nordic Questionnaire for Psychological and Social Factors at Work was sent to all employees (N=1847) in the spring of 2002. The data was analyzed using the SPSS statistical package. The response rate was 80% with 1475 employees returning the questionnaire. Women were 86% (n=1192) of the responders. About 15% of the employees (n=209) had experienced some form of harassment in connection with work. The majority of those had experienced bullying (8% (n=110)). The victims of bullying were more likely to have poor psychosocial work-environment and were less likely to have experienced a positive relationship with supervisors and other staff. There was only minimal association between bullying and seeking medical attention for a selected number of medical conditions. The victims of bullying were more likely to have experienced significant stress recently (p=0.025), to be mentally exhausted at the end of the workday (p=0.013), to have significant sleep difficulties (p=0.001), and poor mental health (p<0.0001), and to be dissatisfied in their job (p<0.0001). In the light of the association between work organization and bullying it is of importance that supervisors and employers are well versified in communication skills as pertains to staff relations and recognizing psychosocial risk factors in the employees' work environment. As victims of bullying are more dissatisfied with their work than others, it is likely that if they become sick and link their illness to the workplace, that they will quit their job. In light of this it is of importance to study the experience of bullying among those receiving benefits due to long-term sickness absence or disability.

Most work in horse stables is performed manually in much the same way as a century ago. It is the least mechanized sector dealing with large animals. People working with horses are exposed to several types of risk for developing musculoskeletal problems, but the work tasks and workload have not been investigated in detail. The aim of this study was to estimate the postural load of the work tasks performed around horses to find those that were harmful and required measures to be taken to reduce physical strain. Altogether, 20 subjects (stable attendants and riding instructors) were video recorded while carrying out their work in the stable, and preparing and conducting riding lessons. The work was analyzed with the Ovako Working posture Analysis System (OWAS) to determine the postural load and to categorize the potential harmfulness of the work postures. Three work tasks involved about 50% of the work positions in the three OWAS categories (AC2 to AC4) where measures for improvement are needed: "mucking out" (50%), "bedding preparation" (48%), and "sweeping" (48%). These work tasks involved over 60% work postures where the back was bent, twisted, or both bent and twisted. Therefore, it is important to find preventive measures to reduce the workload, which could include improved tools, equipment, and work technique.

Work organization, including long working hours, irregular work schedules, and job stress, has been associated with increased cardiometabolic disease (CMD) risk for numerous working populations. The purpose of this study was to examine the associations between work hours, work schedules, job stress, and CMD risk for a sample of US long-haul truck drivers (LHTDs). A nonexperimental, descriptive, cross-sectional design was employed to collect survey and anthropometric data from 260 US LHTDs at a major truck stop. The mean BMI was 33.40 kg/m 2 and mean waist circumference was 114.77 cm. Using logistic regression, researchers found longer work hours, especially greater than 11 hours daily, were associated with increased odds for an extremely high risk of CMD. Results support comprehensive and integrated approaches that address work organization, and in particular long working hours, to reduce drivers' CMD risk.

Purpose: Building on the Conservation of Resources theory, this paper examined the unique and interactive associations of negative and positive work-to-family spillover (NWFS and PWFS, respectively) at the individual and organizational level with hotel managers' work exhaustion and satisfaction, beyond job demands and supervisors' leadership style. Design/Methodology/Approach: Guided by the levels of analysis framework, we first tested the unique associations of NWFS and PWFS with emotional exhaustion and job satisfaction at the individual level (571 hotel managers), beyond job demands supervisors' leadership style. Second, using multilevel modeling, we tested the climate effects of NWFS and PWFS on emotional exhaustion and job satisfaction aggregated at the organizational level (41 hotels). Third, we examined the role of the organizational climate of PWFS in the associations of individual-level NWFS with emotional exhaustion and job satisfaction. Findings: Beyond the effects of psychological job demands and supervisor's transformational leadership, at the individual level, hotel managers who experienced higher NWFS than other managers reported more exhaustion and lower job satisfaction, whereas those with higher PWFS reported less exhaustion and higher satisfaction. At the organizational level, working in hotels where the average level of NWFS was higher than other hotels was associated with feeling more exhaustion of the individual members; working in hotels with higher PWFS was associated with feeling less exhaustion. The negative link between individual-level NWFS and job satisfaction was buffered when organization-level PWFS was higher, compared to when it was lower. Originality/Value: This study moves beyond a focus on traditional job characteristics, toward considering individual and organizational experiences in the work-family interface as unique predictors of work exhaustion and satisfaction. Strengths of the study include illuminating organizational work

2008-06-01

The application of knowledge on organization and leadership is important for the promotion of health at workplace. The purpose of this article is to analyse the leadership and organization, including the organizational culture, of a Swedish industrial company in relation to the health of the employees. The leadership in this company has been oriented towards developing and actively promoting a culture and a structure of organization where the employees have a high degree of control over their work situation. According to the employees, this means extensive possibilities for personal development and responsibility, as well as good companionship, which makes them feel well at work. This is also supported by the low sickness rate of the company. The results indicate that the leadership and organization of this company may have been conducive to the health of the employees interviewed. However, the culture of personal responsibility and the structure of self-managed teams seemed to suit only those who were able to manage the demands of the company and adapt to that kind of organization. Therefore, the findings indicate that the specific context of the technology, the environment and the professional level of the employees need to be taken into consideration when analysing the relation between leadership, organization and health at work.

The politics of agenda setting at the global level: key informant interviews regarding the International Labour Organization Decent Work Agenda

PubMed Central

2014-01-01

Background Global labour markets continue to undergo significant transformations resulting from socio-political instability combined with rises in structural inequality, employment insecurity, and poor working conditions. Confronted by these challenges, global institutions are providing policy guidance to protect and promote the health and well-being of workers. This article provides an account of how the International Labour Organization’s Decent Work Agenda contributes to the work policy agendas of the World Health Organization and the World Bank. Methods This qualitative study involved semi-structured interviews with representatives from three global institutions – the International Labour Organization (ILO), the World Health Organization and the World Bank. Of the 25 key informants invited to participate, 16 took part in the study. Analysis for key themes was followed by interpretation using selected agenda setting theories. Results Interviews indicated that through the Decent Work Agenda, the International Labour Organization is shaping the global policy narrative about work among UN agencies, and that the pursuit of decent work and the Agenda were perceived as important goals with the potential to promote just policies. The Agenda was closely linked to the World Health Organization’s conception of health as a human right. However, decent work was consistently identified by World Bank informants as ILO terminology in contrast to terms such as job creation and job access. The limited evidence base and its conceptual nature were offered as partial explanations for why the Agenda has yet to fully influence other global institutions. Catalytic events such as the economic crisis were identified as creating the enabling conditions to influence global work policy agendas. Conclusions Our evidence aids our understanding of how an issue like decent work enters and stays on the policy agendas of global institutions, using the Decent Work Agenda as an illustrative

Establishing fundamental relationships between strain and work function (WF) in organic semiconductors is important not only for understanding electrical properties of organic thin films, which are subject to both intrinsic and extrinsic strains, but also for developing flexible electronic devices. Here we investigate tensile and compressive strain effects on the WF of rubrene single crystals. Mechanical strain induced by thermal expansion mismatch between the substrate and rubrene is quantified by X-ray diffraction. The corresponding WF change is measured by scanning Kelvin probe microscopy. The WF of rubrene increases (decreases) significantly with in-plane tensile (compressive) strain, which agrees qualitatively with density functional theory calculations. An elastic-to-plastic transition, characterized by a steep rise of the WF, occurs at ∼0.05% tensile strain along the rubrene π-stacking direction. The results provide the first concrete link between mechanical strain and WF of an organic semiconductor and have important implications for understanding the connection between structural and electronic disorder in soft organic electronic materials.

View-Based Organization and Interplay of Spatial Working and Long-Term Memories

Röhrich, Wolfgang G.; Hardiess, Gregor; Mallot, Hanspeter A.

Space perception provides egocentric, oriented views of the environment from which working and long-term memories are constructed. “Allocentric” (i.e. position-independent) long-term memories may be organized as graphs of recognized places or views but the interaction of such cognitive graphs with egocentric working memories is unclear. Here we present a simple coherent model of view-based working and long-term memories, together with supporting evidence from behavioral experiments. The model predicts that within a given place, memories for some views may be more salient than others, that imagery of a target square should depend on the location where the recall takes place, and that recall favors views of the target square that would be obtained when approaching it from the current recall location. In two separate experiments in an outdoor urban environment, pedestrians were approached at various interview locations and asked to draw sketch maps of one of two well-known squares. Orientations of the sketch map productions depended significantly on distance and direction of the interview location from the target square, i.e. different views were recalled at different locations. Further analysis showed that location-dependent recall is related to the respective approach direction when imagining a walk from the interview location to the target square. The results are consistent with a view-based model of spatial long-term and working memories and their interplay. PMID:25409437

Circadian rhythms as a basis for work organization: a study with live line electricians.

With the assumption that circadian rhythms influence human performance, the work of live line electricians was reorganized and evaluated. The hypothesis was that in highly physical and attention-demanding work, the organization of tasks, according to the ideal period of day and day of week, should diminish stress and consequent work risks. There are only a few studies reporting the work of electricians and even fewer approaching work organization. Moreover, these investigations often do not consider human physiological limitations and capabilities as well as task demands. A new work system was proposed with consideration of (a) the circadian cycles and homeostatic processes; (b) the effect of heat, which is a zeitgeber (synchronizer) for the biological clocks; and (c) the degree of physical and mental demands of the different performed tasks, which was assessed on the basis of opinions of the electricians and physiological markers of stress that are controlled by circadian rhythms. The traditional and new systems were compared on the basis of two cognitive indices (the arrangement of matchsticks and the perception of a minute) and three physiological markers of mental-to-physical loads (heart frequency and the level of adrenaline and noradrenaline). Both physical and mental loads were reduced in the new system. Work organization should include consideration of human circadian rhythms, mainly when stressful and high-risk tasks are involved. The findings can be applied in any work design, but they are especially suited for highly demanding work carried out outdoors.

Nurse middle managers are in an ideal position to facilitate patient-centred care. However, their contribution is underexposed in literature due to difficulties to articulate this in practice. This paper explores how nurse middle managers contribute to patient-centred care in hospitals. A combination of time-use analysis and ethnographic work was used to disclose their contribution to patient-centred care at a micro level. Sixteen nurse managers were shadowed for over 560 hours in four hospitals. Some nurse middle managers seldom contribute to patient-centred care. Others are involved in direct patient care, but this does not result in patient-centred practices. At one hospital, the nurse middle managers did contribute to patient-centred care. Here balancing between "organizing work" and "caring work" is seen as a precondition for their patient-centeredness. Other important themes are feedback mechanisms; place matters; with whom to talk and how to frame the issues at stake; and behavioral style. Both "hands-on" and "heads-on" caring work of nurse middle managers enhances their patient-centeredness. This study is the first of its kind to obtain insight in the often difficult to articulate "doings" of nurse middle managers with regard to patient-centred care through combining time-use analysis with ethnographic work. © 2017 John Wiley & Sons Ltd.

Though synthetic organic colorants are used in various applications nowadays, there is the concern that impurities by-produced during the manufacturing and degradation products in some of these colorants are persistent organic pollutants and carcinogens. Thus, it is important to identify the synthetic organic colorants in various products, such as commercial paints, ink, cosmetics, food, textile, and plastics. Dyes, which are soluble in water and other solvents, could be analyzed by chromatographic methods. In contrast, it is difficult to analyze synthetic organic pigments by these methods because of their insolubility. This review is an overview of mass spectrometric analysis of synthetic organic pigments by various ionization methods. We highlight a recent study of textile samples by atmospheric pressure solid analysis probe MS. Furthermore, the mass spectral features of synthetic organic pigments and their separation from other components such as paint media and plasticizers are discussed.

Alcohol use and misuse: What are the contributions of occupation and work organization conditions?

2008-01-01

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

The integration of quality management initiatives, particularly total quality management (TQM), and ergonomics has received increasing attention from scholars and practitioners. Above all, the question of how TQM programs relate to ergonomic aspects of organizational design and culture is at the center of this discussion. This study examines how elements of a "typical", Deming-inspired, TQM program in the public sector interact with the work environment. Elements of the TQM program were defined and measured using the Malcom Baldridge Award criteria. The specific elements examined were "Management Support of Quality", "Information and Analysis", "Human Resources", "Processes and Quality Results", and "Customer Focus and Satisfaction". The relationship between these TQM elements and the work environment were defined through five separate hypotheses. The work environment was described by the constructs "Supervisor Support", "Task Clarity", "Task Orientation", and "Innovation". Data were obtained through survey questionnaires administered to employees of four departments in a municipal government organization. Results supported three of the hypotheses, but produced some unanticipated outcomes with regard to the other two. Namely, "Management Support of Quality" was significantly related to "Supervisor Support", "Task Orientation", "Task Clarity" and "Innovation"; "Human Resources" was significantly related to "Supervisor Support"; "Processes and Quality Results" was significantly related to "Task Orientation" and "Innovation". Contrary to predicted "Information and Analysis" was negatively related to "Innovation", and "Customer Focus" was unrelated to any of the outcome variables. The relationships between these TQM elements and work environment dimensions are discussed. Implications for TQM and ergonomic practice are analyzed, and directions for future research proposed.

The study aimed to determine the risk factors for incident carpal tunnel syndrome (CTS) in a large working population, with a special focus on factors related to work organization. In 2002-2005, 3710 workers were assessed and, in 2007-2010, 1611 were re-examined. At baseline all completed a self-administered questionnaire about personal/medical factors and work exposure. CTS symptoms and physical examination signs were assessed by a standardized medical examination at baseline and follow-up. The risk of "symptomatic CTS" was higher for women (OR = 2.9 [1.7-5.2]) and increased linearly with age (OR = 1.04 [1.00-1.07] for 1-year increment). Two work organizational factors remained in the multivariate risk model after adjustment for the personal/medical and biomechanical factors: payment on a piecework basis (OR = 2.0, 95% CI 1.1-3.5) and work pace dependent on automatic rate (OR = 1.9, 95% CI 0.9-4.1). Several factors related to work organization were associated with incident CTS after adjustment for potential confounders. Copyright © 2014 Elsevier Ltd and The Ergonomics Society.

Integrated System Design: Promoting the Capacity of Sociotechnical Systems for Adaptation through Extensions of Cognitive Work Analysis

PubMed Central

Naikar, Neelam; Elix, Ben

2016-01-01

This paper proposes an approach for integrated system design, which has the intent of facilitating high levels of effectiveness in sociotechnical systems by promoting their capacity for adaptation. Building on earlier ideas and empirical observations, this approach recognizes that to create adaptive systems it is necessary to integrate the design of all of the system elements, including the interfaces, teams, training, and automation, such that workers are supported in adapting their behavior as well as their structure, or organization, in a coherent manner. Current approaches for work analysis and design are limited in regard to this fundamental objective, especially in cases when workers are confronted with unforeseen events. A suitable starting point is offered by cognitive work analysis (CWA), but while this framework can support actors in adapting their behavior, it does not necessarily accommodate adaptations in their structure. Moreover, associated design approaches generally focus on individual system elements, and those that consider multiple elements appear limited in their ability to facilitate integration, especially in the manner intended here. The proposed approach puts forward the set of possibilities for work organization in a system as the central mechanism for binding the design of its various elements, so that actors can adapt their structure as well as their behavior—in a unified fashion—to handle both familiar and novel conditions. Accordingly, this paper demonstrates how the set of possibilities for work organization in a system may be demarcated independently of the situation, through extensions of CWA, and how it may be utilized in design. This lynchpin, conceptualized in the form of a diagram of work organization possibilities (WOP), is important for preserving a system's inherent capacity for adaptation. Future research should focus on validating these concepts and establishing the feasibility of implementing them in industrial

Issayev, T; Masalimova, A; Magzumova, R

2018-03-01

In modern conditions, there is a tendency to replace the qualification approach of assessing economists in medical organizations - competence. The purpose of the study was to identify the professional and personal abilities of economists in medical organizations to actively participate in the management decisions of the medical organization in the transition from public administration to the right of economic management. The study was carried out in 3 stages. At the first stage, the degree of influence of the experience of the economist, the frequency of training and its burden on the profitability of the medical organization was analyzed. At the second stage - the personal evaluation of the respondents by psychodiagnostic methods (memory, attention, the level of the person's orientation, self-esteem, the level of personal claims). At the third stage, the data of professional behavior and personal evaluation were summarized in the table of SWOT-analysis factors, for determining the personnel strategy of development of economists in medical organizations. The sample size was 43 respondents, which amounted to 10.3% of the participation of medical organizations. The results of the SWOT analysis of the personal and professional qualities of medical economists in medical organizations showed the predominance of weaknesses in corporate competencies among medical economists over strong ones, while personal opportunities prevail over risks. In general, the professional-personal SWOT analysis showed the prevalence of the possibilities of medical economists (Ps=5,3) over threats (Ps = 4,9), strong (Ps = 4,4) and weak sides (Ps = 3,8). At the same time, the force of influence does not suffice: the length of work for profitability (r = -0.3, p <0.05), and the ratio of one economist to employees on the growth of the specific weight of paid services (r = 0.001, p <0.05). The revealed relationships confirm: a direct strong dependence of the training frequency of economists on the

In this work we describe an analytical method for determining the presence of organic compounds in rocks, limestone, and other composite materials. Our preliminary laboratory experiments on different rocks/limestone show that the organic component in mineralogical matrices is a minor phase on order of hundreds of ppm and can be better detected using high precision liquid chromatography (HPLC). The matrix, which is the major phase, plays an important role in embedding and protecting the organic molecules from the harsh Martian environment. Some rocks bear significant amounts of amino acids therefore, it is possible to identify these phases using powder x-ray diffraction (XRD) by crystallizing the organic. The method of detection/analysis of organics, in particular amino acids, that have been associated with life will be shown in the next section.

Dyspepsia is defined as persistent or recurrent abdominal pain or discomfort centered in the upper abdomen. Dyspepsia represents up to 8.3% of all primary care physician visits and causes huge economic costs to patients and to the economy as a whole. The aim of this study was to measure the influence of dyspepsia on work productivity of people within the Brazilian workforce. Adult patients were enrolled if they met the Roma III criteria for uninvestigated dyspepsia. All patients answered a demographic questionnaire. Productivity impairment was measured by the Work Productivity and Activity Impairment questionnaire. Subjects underwent upper gastrointestinal endoscopy and were classified as having functional or organic dyspepsia. The study protocol was approved by the Ethics Committee of Hospital de Clínicas de Porto Alegre, Brazil. Eight hundred fifty patients with dyspepsia were evaluated: 628 were women (73.9%); mean age was 46.4 ± 12.9 years; 387 (45.5%) were active workers. Among active workers, 32.2% mentioned that dyspepsia had caused absenteeism from work during the preceding week and 78% reported a reduction of the work productivity (presenteeism). The lost work productivity score was 35.7% among all employed patients. The affect on work productivity was similar between patients with functional or organic dyspepsia. Our study showed an important influence of dyspepsia on work productivity. We did not find any statistically significant difference on the influence on work between patients with organic dyspepsia and functional dyspepsia. The social impact of these findings is underscored by taking into account the prevalence (up to 40%) of this condition in Brazil.

Nurses' use of personal mobiles phones at work is a growing trend in healthcare organizations. Although recent studies have explored the positive and negative implications of nurses using personal mobile phones at work, none has yet analyzed the interactions of sociotechnical components (users, technology and policy) on nurses' use of personal mobile phones at work. Identify sociotechnical interactions by analyzing each sociotechnical component (users, technology and policy) that affects nurses' use of personal mobile phones at work. In-depth interviews were conducted with 30 nurses employed in 13 hospitals in the Philippines. The respondents include staff nurses (n=23), charge nurses (n=4), and nurse managers (n=3). Staff nurses were asked on their use of personal mobile phones at work, while charge and nurse managers were asked on their observations regarding staff nurses' use of personal mobile phones at work. Responses were analyzed qualitatively using sociotechnical analysis. Sociotechnical analysis indicated that staff nurses used their personal mobile phones at work in various ways because its use helped in their nursing work, but inevitably altered a few of their routines. Although most hospitals had policies that prohibit the use of mobile phones, staff nurses justified their use of personal mobile phones by using it for work purposes and for the benefit of their patients. Staff nurses highlighted the absence of hospital-provided mobile phones as a key reason for using personal mobile phones at work. Charge nurses and nurse managers also influenced staff nurses' use of personal mobile phones at work. Nurses could use their personal mobile phones at work for work purposes to enhance their clinical performance and improve patient care. Hospital administrators can leverage on nurses' use of personal mobile phones at work by formulating policies that consider both the benefits and potential drawbacks of mobile phone usage. Recommendations are made for the

The development of a qualifying system for reflectance analysis has been the scope of a working group within the International Committee for Coal and Organic Petrology (ICCP) since 1999, when J. Koch presented a system to qualify vitrinite particles according to their size, proximity to bright components and homogeneity of the surface. After some years of work aimed at improving the classification system using photomicrographs, it was decided to run a round robin exercise on microscopy samples. The classification system tested consists of three qualifiers ranging from excellent to low quality vitrinites with an additional option for unsuitable vitrinites. This paper reports on the results obtained by 22 analysts who were asked to measure random reflectance readings on vitrinite particles assigning to each reading a qualifier. Four samples containing different organic matter types and a variety of vitrinite occurrences have been analysed. Results indicated that the reflectance of particles classified as excellent, good or poor compared to the total average reflectance did not show trends to be systematically lower or higher for the four samples analysed. The differences in reflectance between the qualifiers for any given sample were lower than the scatter of vitrinite reflectance among participants. Overall, satisfactory results were obtained in determining the reflectance of vitrinite in the four samples analysed. This was so for samples having abundant and easy to identify vitrinites (higher plant-derived organic matter) as well as for samples with scarce and difficult to identify particles (samples with dominant marine-derived organic matter). The highest discrepancies were found for the organic-rich oil shales where the selection of the vitrinite population to measure proved to be particularly difficult. Special instructions should be provided for the analysis of this sort of samples. The certainty of identification of the vitrinite associated with the vitrinite

Previous research has shown that job characteristics, private life and psychosocial factors partially account for gender difference in work absences because of sickness. Most studies have analysed these factors separately. The aim of the present study was to evaluate whether these explanatory factors act as mediators when they are considered simultaneously. The evaluated data set comprises the merger of two Belgian longitudinal studies, BELSTRESS III and SOMSTRESS. It includes 3821 workers (1541 men) aged 21-66 years, employed in eight organizations. A multiple mediation analysis was performed to explain the higher prevalence among women. Estimated factors were occupational grade, total number of paid working hours per week, job strain, overcommitment, home-work interference and social support at and outside work. Prospective data concerning duration and frequency of medically justified sickness absence (registered by the organizations) were used as outcomes. Overall, the mediating factors partially account for gender difference in sickness absence. The strongest mediator for both outcomes is job strain. In addition, difference in absence duration is mediated by social support at work, whereas difference in frequency is mediated by professional grade and home-work interference. Our results call attention to the necessity to elaborate actual preventive actions aiming at favouring a better positioning of women on the labour market in term of hierarchical level as well as in terms of quality of work for reducing sickness absence in this group.

Strain effects on the work function of an organic semiconductor

Establishing fundamental relationships between strain and work function (WF) in organic semiconductors is important not only for understanding the electrical properties of organic thin films, which are subject to both intrinsic and extrinsic strains, but also for developing flexible electronic devices. Here we investigate tensile and compressive strain effects on the WF of rubrene single crystals. Mechanical strain induced by thermal expansion mismatch between the substrate and rubrene is quantified by X-ray diffraction. The corresponding WF change is measured by scanning Kelvin probe microscopy. The WF of rubrene increases (decreases) significantly with in-plane tensile (compressive) strain, which agrees qualitatively withmore » density functional theory calculations. An elastic-to-plastic transition, characterized by a steep rise of the WF, occurs at ~0.05% tensile strain along the rubrene -stacking direction. The results provide the first concrete link between mechanical strain and the WF of an organic semiconductor and have important implications for understanding the connection between structural and electronic disorder (charge traps) in soft organic electronic materials.« less

NASA Astrophysics Data System (ADS)

Nur, T. B.; Sunoto

2018-02-01

The study examines proposed small biomass-fed Organic Rankine Cycle (ORC) power plant through exergy analysis. The system consists of combustion burner unit to utilize biomass as fuel, and organic Rankine cycle unit to produce power from the expander. The heat from combustion burner was transfered by thermal oil heater to evaporate ORC working fluid in the evaporator part. The effects of adding recuperator into exergy destruction were investigated. Furthermore, the results of the variations of system configurations with different operating parameters, such as the evaporating pressures, ambient temperatures, and expander pressures were analyzed. It was found that the largest exergy destruction occurs during processes are at combustion part, followed by evaporator, condenser, expander, and pump. The ORC system equipped with a recuperator unit exhibited good operational characteristics under wide range conditions compared to the one without recuperator.

Organizations are part of an environment in which they are pressured to meet society's demands and acting in a sustainable way. In an attempt to meet such demands, organizations make use of various management tools, among which, ISO standards are used. Although there are evidences of contributions provided by these standards, it is questionable whether its parameters converge for a possible induction for sustainable development in organizations. This work presents a theoretical study, designed on structuralism world view, descriptive and deductive method, which aims to analyze the convergence of management tools' parameters in ISO standards. In order to support the analysis, a generic framework for possible convergence was developed, based on systems approach, linking five ISO standards (ISO 9001, ISO 14001, OHSAS 18001, ISO 31000 and ISO 26000) with sustainable development and positioning them according to organization levels (strategic, tactical and operational). The structure was designed based on Brundtland report concept. The analysis was performed exploring the generic framework for possible convergence based on Nadler and Tushman model. The results found the standards can contribute to a possible sustainable development induction in organizations, as long as they meet certain minimum conditions related to its strategic alignment.

In 2011, the Danish Ministry of Food, Agriculture and Fisheries launched the Danish Organic Action Plan 2020 intending to double the organic agricultural area in Denmark. This study aims to measure experienced physical and psychological wellbeing at work along with beliefs and attitudes among kitchen workers before and after participating in educational training programmes in organic food conversion. This longitudinal study applied an online self-administered questionnaire among kitchen workers before and after the implementation of an organic food conversion programme with 1-year follow-up. The study targeted all staff members in the participating public kitchens taking part in the organic food conversion process funded by the Danish Organic Action Plan 2020. Of the 448 eligible kitchen workers, 235 completed the questionnaire at baseline (52%) and 149 at follow-up (63% of those surveyed at baseline). No substantive differences between baseline and follow-up measurements of organic food conversion were detected on physical or psychological wellbeing at work. Kitchen workers reported a significant improvement in the perceived food quality, motivation to work and application of nutritional guidelines. Reported organic food percentages for the kitchens also increased significantly (P< 0.001) and a shift from using ready-made food products to producing more food from base was indicated. Within 1 year, a significant increase in motivation to work among kitchen staff was observed with no substantive changes in physical or psychological wellbeing at work identified. The results support the Danish Organic Action Plan 2020 and initiatives of similar kind. © The Author 2015. Published by Oxford University Press on behalf of the European Public Health Association.

Nilsson, Petra; Bringsén, Asa; Andersson, H Ingemar; Ejlertsson, Göran

2010-01-01

Instruments related to work are commonly illuminated from an ill-health perspective. The need for a concise and useable instrument in workplace health promotion governed the aim of this paper which is to present the development process and quality assessment of the Work Experience Measurement Scale (WEMS). A survey, using a questionnaire based on established theories regarding work and health, and a focus group study were performed in hospital settings in 2005 and 2006 respectively. A Principal Component Analysis (PCA) was used to statistically develop a model, and focus group interviews were made to compare quantitative and qualitative results for convergence and corroboration. The PCA resulted in a six factor model of dimensions containing items regarding management, reorganization, internal work experience, pressure of time, autonomy and supportive working conditions. In the analysis of the focus group study three themes appeared and their underlying content was compared to, and matched, with the dimensions of the PCA. The reliability, shown by weighted kappa values, ranged from 0.36 to 0.71, and adequate Cronbach's Alpha values of the dimensions were all above 0.7. The study validity, indicated by discriminant validity, with correlation values that ranged from 0.10 to 0.39, in relation to the content validity appeared to be good when the theoretical content of the WEMS was compared to the content of similar instruments. The WEMS presents a multidimensional picture of work experience. Its theoretical base and the psychometric properties give support for applicability and offer a possibility to measure trends in the work experience over time in health care settings. One intention of the WEMS is to stimulate the ability of organizations and the employees themselves to take action on improving their work experience. The conciseness of the instrument is intended to increase its usability.

Public health agenda setting in a global context: the International Labor Organization's decent work agenda.

Di Ruggiero, Erica; Cohen, Joanna E; Cole, Donald C; Forman, Lisa

2015-04-01

We drew on two agenda-setting theories usually applied at the state or national level to assess their utility at the global level: Kingdon's multiple streams theory and Baumgartner and Jones's punctuated equilibrium theory. We illustrate our analysis with findings from a qualitative study of the International Labor Organization's Decent Work Agenda. We found that both theories help explain the agenda-setting mechanisms that operate in the global context, including how windows of opportunity open and what role institutions play as policy entrepreneurs. Future application of these theories could help characterize power struggles between global actors, whose voices are heard or silenced, and their impact on global policy agenda setting.

Increasing Diversity and Gender Parity by working with Professional Organizations and HBCUs

NASA Astrophysics Data System (ADS)

Wims, T. R.

2017-12-01

Context/Purpose: This abstract proposes tactics for recruiting diverse applicants and addressing gender parity in the geoscience workforce. Methods: The geoscience community should continue to develop and expand a pipeline of qualified potential employees and managers at all levels. Recruitment from professional organizations, which are minority based, such as the National Society of Black Engineers (NSBE), and the Society of Hispanic Professional Engineers (SHPE) provides senior and midlevel scientists, engineers, program managers, and corporate managers/administrators with proven track records of success. Geoscience organizations should consider increasing hiring from the 100+ Historically Black Colleges and Universities (HBCU) which have a proven track records of producing high quality graduates with math, science, computer science, and engineering backgrounds. HBCU alumni have been working in all levels of government and corporate organizations for more than 50 years. Results: Professional organizations, like NSBE, have members with one to 40 years of applicable work experience, who are prime candidates for employment in the geoscience community at all levels. NSBE, also operates pipeline programs to graduate 10,000 bachelor degree minority candidates per year by 2025, up from the current 3,620/year. HBCUs have established educational programs and several pipelines for attracting undergraduate students into the engineering and science fields. Since many HBCUs enroll more women than men, they are also addressing gender parity. Both professional organizations and HBCU's have pipeline programs that reach children in high school. Interpretation: Qualified and capable minority and women candidates are available in the United States. Pipelines for employing senior, mid-level, and junior skill sets are in place, but underutilized by some geoscience companies and organizations.

An important factor influencing duration of breastfeeding is mother's employment status. The main aim of this study was to determine the experience and views of employees (n = 46) in four large public sector organizations concerning breastfeeding support at work. Participants were recruited if they were employed by one of four public service employers and if they were planning to go on maternity leave in the next 6 months, on maternity leave or within 6 months of return from maternity leave. They completed a questionnaire anonymously. Almost 80% of women wanted to continue breastfeeding after returning to work. However, 90% of all respondents were not aware of any employer policy nor offered any information concerning support to enable breastfeeding after returning to work, despite two organizations having a range of maternity- and breastfeeding-related policies in development and some facilities in place. Almost 90% of respondents stated the employers should do more to support breastfeeding. This should include providing pregnant staff with information about breastfeeding support that they should expect and could therefore plan to use, including access to facilities to express and to store breast milk, to enable them to work flexible hours and to take rest breaks during working hours. Recommendations are made for employers.

This analysis describes work organization for Latinas in farmworker families and delineates the associations of work organization with health indicators. Methods 220 Latino women in farmworker families completed interviews from October 2012 - July 2013. Interviews addressed job structure, job demand, job control, and job support. Health measures included stress, depressive symptoms, physical activity, family conflict, and family economic security. Results Three-fifths of the women were employed. Several work organization dimensions, including shift, psychological demand, work safety climate, and benefits, were associated with participant health as expected, based on the work organization and job demands-control-support models. Conclusions Research should address women's health and specific work responsibilities. Occupational safety policy must consider the importance of work organization in the health of vulnerable workers. PMID:25742536

Analysis of Membrane Lipids of Airborne Micro-Organisms

NASA Technical Reports Server (NTRS)

MacNaughton, Sarah

2006-01-01

A method of characterization of airborne micro-organisms in a given location involves (1) large-volume filtration of air onto glass-fiber filters; (2) accelerated extraction of membrane lipids of the collected micro-organisms by use of pressurized hot liquid; and (3) identification and quantitation of the lipids by use of gas chromatography and mass spectrometry. This method is suitable for use in both outdoor and indoor environments; for example, it can be used to measure airborne microbial contamination in buildings ("sick-building syndrome"). The classical approach to analysis of airborne micro-organisms is based on the growth of cultureable micro-organisms and does not provide an account of viable but noncultureable micro-organisms, which typically amount to more than 90 percent of the micro-organisms present. In contrast, the present method provides an account of all micro-organisms, including cultureable, noncultureable, aerobic, and anaerobic ones. The analysis of lipids according to this method makes it possible to estimate the number of viable airborne micro-organisms present in the sampled air and to obtain a quantitative profile of the general types of micro-organisms present along with some information about their physiological statuses.

How Work-Family Research Can Finally Have an Impact in Organizations.

PubMed

Kossek, Ellen Ernst; Baltes, Boris B; Matthews, Russell A

2011-09-01

Although work-family research has mushroomed over the past several decades, an implementation gap persists in putting work-family research into practice. Because of this, work-family researchers have not made a significant impact in improving the lives of employees relative to the amount of research that has been conducted. The goal of this article is to clarify areas where implementation gaps between work-family research and practice are prevalent, discuss the importance of reducing these gaps, and make the case that both better and different research should be conducted. We recommend several alternative but complementary actions for the work-family researcher: (a) work with organizations to study their policy and practice implementation efforts, (b) focus on the impact of rapid technological advances that are blurring work-family boundaries, (c) conduct research to empower the individual to self-manage the work-family interface, and (d) engage in advocacy and collaborative policy research to change institutional contexts and break down silos. Increased partnerships between industrial-organizational (I-O) psychology practitioners and researchers from many industries and disciplines could break down silos that we see as limiting development of the field.

NASA Astrophysics Data System (ADS)

McKague, h L

2001-12-01

The Southwest Research Institute (SwRI) is an independent not-for-profit applied engineering and physical sciences research and development organization. This means that SwRI owes no allegiance to organizations other than its clients. As a not-for-profit organization, SwRI reinvests its net income into the organization to improve, strengthen, and expand facilities and to support internal research and development projects. Located in San Antonio, Texas, on 1200 acres, SwRI employs nearly 2800 staff and occupies nearly 2,000,000 square feet of office space. Its business is about equally divided between commercial and government clients, most of whom have specific scientific and technical problems that need to be solved in a timely, cost-effective manner. Governmental clients include local, state, and federal agencies and foreign governments. Commercial clients include local, national, and international businesses. Earth science disciplines at SwRI include geology, geophysics, hydrology, geochemistry, rock mechanics, mining engineering, and natural hazard assessment. Our overall approach is to systematically examine client problems and develop solutions that may include field work, laboratory work, numerical modeling, or some combination of these approaches. This method of problem solving places a strong emphasis on interdisciplinary teamwork. The work environment at SwRI strikes a balance among the freedom to attack technically important problems, consistent support to professional development, and a strong commitment to meeting client's deadlines and goals. Real problems with real consequences are routinely solved on a tight schedule. The diversity of clients gives exposure to an extraordinarily wide range of problems. Successful employees have sound technical backgrounds, are flexible in accommodating varying clients needs, bring creativity and energy to problem solving and applications of technologies, can work on multiple tasks in parallel, and can communicate

Background: The present study was firstly aimed to find out the nature of stressful life events arising out of the innovative challenges in modernized organizations; and secondly, it tried to identify the relationship between innovative work behavior of managers and the levels of stress arising out of stressful events in modernized organizations (public and private) in West Bengal. Materials and Methods: Data was collected from a sample of 200 managers, by using 3 tools (General Information Schedule, Life Event Inventory and Innovative Work Behavior Scale) through a face-to-face interview. Responses were subjected to both quantitative and qualitative analyses. The data was statistically treated for ‘t’ and ANOVA. Results: Data highlighted the fact that the qualitative profile of stressful events in the lives of managers expressed specificity in terms of their organizational type (public- and private-sector modernized organizations), and levels of stress from stressful life events were significantly higher among the modernized private-sector managers than those among public-sector managers. The prevalence of innovative work behavior was moderately higher among managers of private-sector modernized organizations than their counterparts in public-sector organizations. The trends of innovative work behavior of the managers indicated much variability due to interaction of their level of perceived stressful challenges for innovation and the global forces of change that have unleashed dynamic, systematic and higher expectation level from them.

The purpose of this research is to (1) show the effectiveness and success of self-directed work teams within the organization, (2) emphasize the importance of team building in the success of the team, and (3) assist organizations in building self-directed work teams. The researcher used a direct survey and studied the following team building techniques: (1) Is the team`s mission clearly defined to each team member? (2) Are the goals clearly defined and achievable by all team members? (3) Will empowerment (decision-making power) be given equally to all team members? (4) Will open and honest communication be allowed among teammore » members? (5) Will each team member be respected and valued for his/her position on the team? (6) Are self-directed work teams effectively rewarded for accomplishments? (7) Have team members received adequate training to effectively complete their job tasks? Upon completion of the literature review and statistical data, and after analyzing the seven areas of team building techniques, it was determined three of the four teams were successful and effective. The only area of concern to the organization is that the participants felt they did not have true ownership of their teams; that is, team members were not given full empowerment. According to this study and the review of literature, full empowerment must be given to achieve successful and effective teams. If true empowerment is not given, the team will suffer in other areas of team building, and the organization will lose a valuable tool.« less

Work-related accidents result in human suffering and economic losses and are considered as a major health problem worldwide, especially in the economically developing world. To introduce seasonal autoregressive moving average (ARIMA) models for time series analysis of work-related accident data for workers insured by the Iranian Social Security Organization (ISSO) between 2000 and 2011. In this retrospective study, all insured people experiencing at least one work-related accident during a 10-year period were included in the analyses. We used Box-Jenkins modeling to develop a time series model of the total number of accidents. There was an average of 1476 accidents per month (1476·05±458·77, mean±SD). The final ARIMA (p,d,q) (P,D,Q)s model for fitting to data was: ARIMA(1,1,1)×(0,1,1)12 consisting of the first ordering of the autoregressive, moving average and seasonal moving average parameters with 20·942 mean absolute percentage error (MAPE). The final model showed that time series analysis of ARIMA models was useful for forecasting the number of work-related accidents in Iran. In addition, the forecasted number of work-related accidents for 2011 explained the stability of occurrence of these accidents in recent years, indicating a need for preventive occupational health and safety policies such as safety inspection.

Recent breakthroughs in remote-sensing technology have led to the development of high spectral resolution imaging sensors for observation of earth surface features. This research was conducted to evaluate the effects of organic matter content and composition on narrowband soil reflectance across the visible and reflective infrared spectral ranges. Organic matter from four Indiana agricultural soils, ranging in organic C content from 0.99 to 1.72 percent, was extracted, fractionated, and purified. Six components of each soil were isolated and prepared for spectral analysis. Reflectance was measured in 210 narrow bands in the 400- to 2500-nm wavelength range. Statistical analysis of reflectance values indicated the potential of high dimensional reflectance data in specific visible, near-infrared, and middle-infrared bands to provide information about soil organic C content, but not organic matter composition. These bands also responded significantly to Fe- and Mn-oxide content.

Just love in live organ donation.

PubMed

Zeiler, Kristin

2009-08-01

Emotionally-related live organ donation is different from almost all other medical treatments in that a family member or, in some countries, a friend contributes with an organ or parts of an organ to the recipient. Furthermore, there is a long-acknowledged but not well-understood gender-imbalance in emotionally-related live kidney donation. This article argues for the benefit of the concept of just love as an analytic tool in the analysis of emotionally-related live organ donation where the potential donor(s) and the recipient are engaged in a love relation. The concept of just love is helpful in the analysis of these live organ donations even if no statistical gender-imbalance prevails. It is particularly helpful, however, in the analysis of the gender-imbalance in live kidney donations if these donations are seen as a specific kind of care-work, if care-work is experienced as a labour one should perform out of love and if women still experience stronger pressures to engage in care-work than do men. The aim of the article is to present arguments for the need of just love as an analytic tool in the analysis of emotionally-related live organ donation where the potential donor(s) and the recipient are engaged in a love relation. The aim is also to elaborate two criteria that need to be met in order for love to qualify as just and to highlight certain clinical implications.

Organic contamination of ground water at Gas Works Park, Seattle, Washington

Turney, G.L.; Goerlitz, D.F.

1990-01-01

Gas Works Park, in Seattle, Washington, is located on the site of a coal and oil gasification plant that ceased operation in 1956. During operation, many types of wastes, including coal, tar, and oil, accumulated on-site. The park soil is currently (1986) contaminated with compounds such as polynuclear aromatic hydrocarbons, volatile organic compounds, trace metals, and cyanide. Analyses of water samples from a network of observation wells in the park indicate that these compounds are also present in the ground water. Polynuclear aromatic hydrocarbons and volatile organic compounds were identified in ground water samples in concentrations as large as 200 mg/L. Concentrations of organic compounds were largest where ground water was in contact with a non-aqueous phase liquid in the soil. Where no non-aqueous phase liquid was present, concentrations were much smaller, even if the ground water was in contact with contaminated soils. This condition is attributed to weathering processes in which soluble, low-molecular-weight organic compounds are preferentially dissolved from the non-aqueous phase liquid into the ground water. Where no non-aqueous phase liquid is present, only stained soils containing relatively insoluble, high-molecular-weight compounds remain. Concentrations of organic contaminants in the soils may still remain large.

Analysis of cold worked holes for structural life extension

1994-01-01

Cold working holes for improved fatigue life of fastener holes are widely used on aircraft. This paper presents methods used by the authors to determine the percent of cold working to be applied and to analyze fatigue crack growth of cold worked fastener holes. An elastic, perfectly-plastic analysis of a thick-walled tube is used to determine the stress field during the cold working process and the residual stress field after the process is completed. The results of the elastic/plastic analysis are used to determine the amount of cold working to apply to a hole. The residual stress field is then used to perform damage tolerance analysis of a crack growing out of a cold worked fastener hole. This analysis method is easily implemented in existing crack growth computer codes so that the cold worked holes can be used to extend the structural life of aircraft. Analytical results are compared to test data where appropriate.

The Working Women's Forum: organizing for credit and change.

Chen, M

1983-01-01

The Working Women's Forum (WWF), established in Madras in 1978, has brought together over 13,000 poor urban women around the issue of credit. Most women who live in the slums of Madras work as small-scale traders and vendors, their earnings often providing over half the family income. Interviews with these women revealed that their primary concern was increasing their earning capacity. The WWF was set up to enable these women to obtain low interest loans to expand their businesses. The key element in the WWF structure is the neighborhood loan group, comprised of 10-20 women from the same area who act as mutual guarantors for the loans of all group members. Over 7000 women have received loans and the repayment rate has been over 90%. About 2800 new jobs or businesses have been created, and earnings have increased an average of 50% in existing enterprises. Women report that they are eating better quality and more varied foods as a result of their increased income. The WWF is expanding its activities to address the political and social problems of working women as well. The Forum operates day care centers, skills training centers, and remedial classes for schoolchildren. In 1980 the WWF launched a family planning program in which field workers (who are drawn from the WWF membership and paid $18 per month) disseminate information on health, nutrition, and family planning to families in their communities. According to a staff member, this program was an outcome of the realization that "income generation and large families do not go together." The WWF also promotes intercaste, no dowry marriages and lobbies for public services. Women have become more confident of the possibility of gaining control over their lives, including their fertility. The WWF experience demonstrates that an organization does not need a lot of money, educated staff, or technical expertise to reach poor women. The Forum's success is attributed to its selection of one critical issue, utilization of

Motor vehicle crashes are the leading cause of injury-related mortality in children, with a higher rate of multiorgan injuries than in adults. This may be related to increased solid organ volume relative to abdominal cavity and decreased protection of an underdeveloped cartilaginous rib cage in young children. To date, these anatomic relationships have not been fully described. Our study used analytic morphomics to obtain precise measures of the pediatric liver, spleen, kidneys, and ribs. This pilot study included 215 trauma patients (aged 0-18 years) with anonymized computed tomography (CT) scans. Liver, spleen, and kidney volumes were modeled using semiautomatic algorithms (MATLAB 2013a, MathWorks Inc., Natick, MA). Thirty-one scans were adequate to model the rib cage. Pearson's r was used to correlate absolute organ volume, fractional organ volume, and organ exposure with age and weight. Spleen, right and left kidney, and liver volumes increased with age and weight (p < 0.01). Right/left kidney and liver fractional volumes decreased with age (p < 0.01), whereas spleen fractional volume remained relatively constant. Exposed surface area of the liver only significantly decreased with age in the anterior (p < 0.01), right (p < 0.01), and posterior views (p = 0.02). With this study, we have demonstrated the ability to model solid organ and rib cage anatomy of children using cross-sectional imaging. In younger children, there may be a decrease in fractional organ volume and increase in liver surface exposure, although analysis of a larger sample size is warranted. In the future, this information may be used to improve the design of safety restraints in motor vehicles.

[Job demands and work-family conflict in a health care staff. The role of work shifts].

2013-01-01

Work-family conflict (wfc), that originates from an incompatibility between the job and the family demands, is a very relevant topic in health care context, as suggested by NEXT study. Work overload and schedule organization are dimensions that can affect wfc, and particularly, studies indicate work shifts as one of its main determinants, as they limit the work-family balance and represent one of the prime risk factors for workers' health. The aim of this study was to detect the role of some job demands (both general and specific) and of schedule organization in determining the wfc experience, with particular attention to work shifts. Respondents to our questionnaire are 207 nurses of a north Italian public health organization. They are mostly women (92.8%) and their average age is 42. Data analysis shows that wfc is mostly influenced by work shifts, but also by work overload, cognitive load and by on-call availability. Staff working on shifts and on-call availability perceive a higher wfc than their colleagues without work shifts and on-call availability. The central role of work shifts in determining wfc suggests the need to act on schedule organization and on training programs for supervisors and workers.

Ergonomics and quality management--humans in interaction with technology, work environment, and organization.

PubMed

Eklund, J A

1999-01-01

In many studies, ergonomics has been shown to influence human performance. The aim of this paper was to demonstrate important ergonomics influences on quality in industrial production, from the perspective of interactions between humans, technology, organization, and work environment. A second aim was to elaborate on the implications of these findings for the development of quality management strategies. This paper shows that ergonomics problems in terms of adverse work environmental conditions, inappropriate design of technology, and an unsuitable organization are important causes of quality deficiencies. Problem solving aimed at improving ergonomics, quality, and productivity simultaneously is likely to obtain support from most of the interest parties of the company, and may also enhance participation. Ergonomics has the potential of becoming a driving force for the development of new quality management strategies.

Moral distress is a stress symptom arising from situations that involve ethical dimensions where the health-care provider believes that he or she is unable to preserve all interests and values at stake. The aims of this study were to evaluate the impact of, and identify possible differences in, moral distress in podiatric physicians in the United States and Spain and to determine the ethical principles most closely related to moral distress. A 2008 e-mail survey of 93 US podiatric physicians and 93 Spanish podiatric physicians (N = 186) presented statements about different ethical dilemmas, values, and goals in the workplace. Although moral distress is strongly present across the sample for all of the questions, the US sample shows higher levels of any kind of moral distress concerning questions about patients' treatment and economic constraints, overload of paperwork, and acting against one's conscience. In the US sample, 91.4% of physicians agreed mostly or completely with the statement that they often had to compromise their own values to cope with the demands of the workplace; 89.25% of US podiatric physicians indicated that their own professional values were congruent with the values of the organization; and a similar percentage (77.5%) reported a strong identification with the goals and framework of their work organization. The Spanish sample had similar results. The results underline the significance of moral distress for both samples, mainly related to time constraints and organizational aspects concerning patients and lack of resources.

Social support at work and affective commitment to the organization: the moderating effect of job resource adequacy and ambient conditions.

PubMed

Rousseau, Vincent; Aubé, Caroline

2010-01-01

This study investigated whether both supervisor and coworker support may be positively related to affective commitment to the organization on one hand; and on the other hand, it examined the moderating effect of job resource adequacy and ambient conditions on these relationships. The sample included 215 participants working within a health care organization. Results of regression analysis showed that supervisor and coworker support have an additive effect on affective commitment. Hierarchical regression analyses indicated that supervisor and coworker support are more strongly related to affective commitment when job resource adequacy is high. Furthermore, ambient conditions moderate the relationship between supervisor support and affective commitment in such a way that favorable ambient conditions strengthen this relationship. Overall, these findings reinforce the importance of taking into account contingent factors in the study of antecedents of affective commitment to the organization.

Self-organization in chronic pain: a concept analysis.

PubMed

Monsivais, Diane

2005-01-01

The purpose of this article is to examine the concept of self-organization in chronic pain using Rodgers' (2000) evolutionary approach. This article describes the antecedents, attributes, and consequences of self-organization in chronic pain. Self-organization in chronic pain may be achieved through the attributes of being believed, accessing credible resources, and taking action and responsibility. Self-organization occurs when the patient with pain develops a transformed identity, new insights, and is an active, in-control participant in care. Chronic pain is a common and costly problem, and recognition of the key attributes of self-organization in this condition is an important step in promoting positive health outcomes. Rehabilitation nurses play a key role in providing credible resources and working with the patient to take action and responsibility.

Novel procedures for analytical authentication of organic plant products are urgently needed. Here we present the first study encompassing stable isotopes of hydrogen, carbon, nitrogen, oxygen, magnesium and sulphur as well as compound-specific nitrogen and oxygen isotope analysis of nitrate for discrimination of organically and conventionally grown plants. The study was based on wheat, barley, faba bean and potato produced in rigorously controlled long-term field trials comprising 144 experimental plots. Nitrogen isotope analysis revealed the use of animal manure, but was unable to discriminate between plants that were fertilised with synthetic nitrogen fertilisers or green manures from atmospheric nitrogen fixing legumes. This limitation was bypassed using oxygen isotope analysis of nitrate in potato tubers, while hydrogen isotope analysis allowed complete discrimination of organic and conventional wheat and barley grains. It is concluded, that multi-isotopic analysis has the potential to disclose fraudulent substitutions of organic with conventionally cultivated plants. Copyright © 2013 Elsevier Ltd.

Purpose Conduct a social network analysis of the health and non-health related organizations that participate in the Bogotá’s Ciclovía Recreativa (Ciclovía). Design Cross sectional study. Setting Ciclovía is a multisectoral community-based mass program in which streets are temporarily closed to motorized transport, allowing exclusive access to individuals for leisure activities and PA. Subjects 25 organizations that participate in the Ciclovía. Measures Seven variables were examined using network analytic methods: relationship, link attributes (integration, contact, and importance), and node attributes (leadership, years in the program, and the sector of the organization). Analysis The network analytic methods were based on a visual descriptive analysis and an exponential random graph model. Results Analysis shows that the most central organizations in the network were outside of the health sector and includes Sports and Recreation, Government, and Security sectors. The organizations work in clusters formed by organizations of different sectors. Organization importance and structural predictors were positively related to integration, while the number of years working with Ciclovía was negatively associated with integration. Conclusion Ciclovía is a network whose structure emerged as a self-organized complex system. Ciclovía of Bogotá is an example of a program with public health potential formed by organizations of multiple sectors with Sports and Recreation as the most central. PMID:23971523

A Multiagent Modeling Environment for Simulating Work Practice in Organizations

NASA Technical Reports Server (NTRS)

Sierhuis, Maarten; Clancey, William J.; vanHoof, Ron

2004-01-01

In this paper we position Brahms as a tool for simulating organizational processes. Brahms is a modeling and simulation environment for analyzing human work practice, and for using such models to develop intelligent software agents to support the work practice in organizations. Brahms is the result of more than ten years of research at the Institute for Research on Learning (IRL), NYNEX Science & Technology (the former R&D institute of the Baby Bell telephone company in New York, now Verizon), and for the last six years at NASA Ames Research Center, in the Work Systems Design and Evaluation group, part of the Computational Sciences Division (Code IC). Brahms has been used on more than ten modeling and simulation research projects, and recently has been used as a distributed multiagent development environment for developing work practice support tools for human in-situ science exploration on planetary surfaces, in particular a human mission to Mars. Brahms was originally conceived of as a business process modeling and simulation tool that incorporates the social systems of work, by illuminating how formal process flow descriptions relate to people s actual located activities in the workplace. Our research started in the early nineties as a reaction to experiences with work process modeling and simulation . Although an effective tool for convincing management of the potential cost-savings of the newly designed work processes, the modeling and simulation environment was only able to describe work as a normative workflow. However, the social systems, uncovered in work practices studied by the design team played a significant role in how work actually got done-actual lived work. Multi- tasking, informal assistance and circumstantial work interactions could not easily be represented in a tool with a strict workflow modeling paradigm. In response, we began to develop a tool that would have the benefits of work process modeling and simulation, but be distinctively able to

There is widespread agreement that work organization is an important element of occupational safety and health, but the health effects of many aspects of work organization are likely to vary considerably across different sectors of work and geographies. We examined existing employment policies and work organization-related research relevant specifically to immigrant workers in the Agriculture, Forestry, and Fishing (AgFF) Sector of the US workforce focusing, when possible, on the southeastern US. A number of specific aspects of work organization within AgFF subsectors have been described, but most of this literature exists outside the purview of occupational health. There are few studies that directly examine how attributes of work organization relevant to the AgFF Sector affect workers', much less immigrant workers', occupational health exposures and outcomes. In contrast to the broader literature, research linking occupational health outcomes to work organization in the AgFF Sector is limited and weak. A systematic program of research and intervention is needed to develop strategies that eliminate or substantially mitigate the deleterious health effects of occupational exposures whose origins likely lie in the organization of AgFF work.

A meta-analysis of the relationship between organizational citizenship behavior and counterproductive work behavior.

PubMed

Dalal, Reeshad S

2005-11-01

Job performance is increasingly being seen to encompass constructs such as organizational citizenship behavior (OCB) and counterproductive work behavior (CWB). To clarify the OCB-CWB relationship, a meta-analysis was conducted. Results indicate a modest negative relationship (p = -0.32). The relationship strength did not increase appreciably when the target of the behavior (the organization vs. other employees) was the same. Moreover, OCB and CWB exhibited somewhat distinct patterns of relationships with antecedents. The OCB-CWB relationship was moderated by the source of the ratings, the presence of antithetical items, and the type of response options. An employee-centric perspective is proposed whereby both OCB and CWB are perceived as adaptive behavior. Implications for organizations are discussed. ((c) 2005 APA, all rights reserved).

Analysis of Organic Compounds in Mars Analog Samples

The detailed characterization of organic compounds that might be preserved in rocks, ices, or sedimentary layers on Mars would be a significant step toward resolving the question of the habitability and potential for life on that planet. The fact that the Viking gas chromatograph mass spectrometer (GCMS) did not detect organic compounds should not discourage further investigations since (a) an oxidizing environment in the near surface fines analyzed by Viking is likely to have destroyed many reduced carbon species; (b) there are classes of refractory or partially oxidized species such as carboxylic acids that would not have been detected by the Viking GCMS; and (c) the Viking landing sites are not representative of Mars overall. These factors motivate the development of advanced in situ analytical protocols to carry out a comprehensive survey of organic compounds in martian regolith, ices, and rocks. We combine pyrolysis GCMS for analysis of volatile species, chemical derivatization for transformation of less volatile organics, and laser desorption mass spectrometry (LDMS) for analysis of elements and more refractory, higher-mass organics. To evaluate this approach and enable a comparison with other measurement techniques we analyze organics in Mars simulant samples.

2015-03-01

While the use of Work Domain Analysis as a methodological framework in cognitive engineering is increasing rapidly, verification and validation of work domain models produced by this method are becoming a significant issue. In this article, we propose the use of a method based on Turing machine formalism named "Turing Machine Task Analysis" to verify and validate work domain models. The application of this method on two work domain analyses, one of car driving which is an "intentional" domain, and the other of a ship water system which is a "causal domain" showed the possibility of highlighting improvements needed by these models. More precisely, the step by step analysis of a degraded task scenario in each work domain model pointed out unsatisfactory aspects in the first modelling, like overspecification, underspecification, omission of work domain affordances, or unsuitable inclusion of objects in the work domain model.

Background Work-related accidents result in human suffering and economic losses and are considered as a major health problem worldwide, especially in the economically developing world. Objectives To introduce seasonal autoregressive moving average (ARIMA) models for time series analysis of work-related accident data for workers insured by the Iranian Social Security Organization (ISSO) between 2000 and 2011. Methods In this retrospective study, all insured people experiencing at least one work-related accident during a 10-year period were included in the analyses. We used Box–Jenkins modeling to develop a time series model of the total number of accidents. Results There was an average of 1476 accidents per month (1476·05±458·77, mean±SD). The final ARIMA (p,d,q) (P,D,Q)s model for fitting to data was: ARIMA(1,1,1)×(0,1,1)12 consisting of the first ordering of the autoregressive, moving average and seasonal moving average parameters with 20·942 mean absolute percentage error (MAPE). Conclusions The final model showed that time series analysis of ARIMA models was useful for forecasting the number of work-related accidents in Iran. In addition, the forecasted number of work-related accidents for 2011 explained the stability of occurrence of these accidents in recent years, indicating a need for preventive occupational health and safety policies such as safety inspection.

2012-12-01

In welfare policy and practical work it is unclear what the concept of work ability involves and assessments may be different among involved actors, partly due to a lack of theoretical research in relation to regulations and practice. Based on theoretical and legal aspects of work ability the aim of the study is to analyze stakeholders' perspectives on work ability in local practice by studying multi-stakeholder meetings. The material comprises nine digitally recorded multi-stakeholder meetings. Apart from the sick-listed individual, representatives from the public Social Insurance Agency, health care, employers, public employment service and the union participated in the meeting. The material was analyzed using qualitative content analysis. Three perspectives on work ability were identified: a medical perspective, a workplace perspective and a regulatory perspective. The meetings developed into negotiations of responsibility concerning workplace adjustments, rehabilitation efforts and financial support. Medical assessments served as objective expert statements to legitimize stakeholders' perspectives on work ability and return to work. Although the formal goal of the status meeting was to facilitate stakeholder collaboration, the results demonstrates an unequal distribution of power among cooperating actors where the employers had the "trump card" due to their possibilities to offer workplace adjustments. The employer perspective often determined whether or not persons could return to work and if they had work ability.

Perceptions of work conditions have proven to be important to the well-being of workers. However, customer loyalty, employee retention, revenue, sales, and profit are essential to the success of any business. It is known that these outcomes are correlated with employee attitudes and perceptions of work conditions, but the research into direction of causality has been inconclusive. Using a massive longitudinal database that included 2,178 business units in 10 large organizations, we found evidence supporting the causal impact of employee perceptions on these bottom-line measures; reverse causality of bottom-line measures on employee perceptions existed but was weaker. Managerial actions and practices can impact employee work conditions and employee perceptions of these conditions, thereby improving key outcomes at the organizational level. Perceptions of specific work conditions that engage employees in their work provide practical guidance in how best to manage people to obtain desired results. © The Author(s) 2010.

High work function transparent middle electrode for organic tandem solar cells

2010-04-01

The use of poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) in combination with ZnO as middle electrode in solution-processed organic tandem solar cells requires a pH modification of the PEDOT:PSS dispersion. We demonstrate that this neutralization leads to a reduced work function of PEDOT:PSS, which does not affect the performance of polythiophene:fullerene solar cells, but results in a lower open-circuit voltage of devices based on a polyfluorene derivative with a higher ionization potential. The introduction of a thin layer of a perfluorinated ionomer recovers the anode work function and gives an open-circuit voltage of 1.92 V for a double junction polyfluorene-based solar cell.

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.

Background Surveillance is needed to capture work organization characteristics and to identify their trends. Methods Data from the 2010 National Health Interview Survey (NHIS) were used to calculate prevalence rates for four work organization characteristics (long work hours, non-standard work arrangements, temporary positions, and alternative shifts) overall, and by demographic characteristics, and industry and occupation of current/recent employment. Results Data were available for 27,157 adults, of which 65% were current/recent workers. Among adults who worked in the past 12 months, 18.7% worked 48 hr or more per week, 7.2% worked 60 hr or more per week, 18.7% had non-standard work arrangements, 7.2% were in temporary positions, and 28.7% worked an alternative shift. Conclusions Prevalence rates of work organization characteristics are provided. These national estimates can be used to help occupational health professionals and employers to identify emerging occupational safety and health risks, allow researchers to examine associations with health, and use the data for benchmarking.

Organ transplantation has increased in Italy over the last decade. Thus, an increasing number of workers may face the problem of returning to work. The aim of this study was to provide an assessment of working ability of transplant recipients in comparison with their actual employment status. This study was based on 150 patients who underwent transplantation since 1994 and who underwent periodic post-transplantation examination during 2012. Fifty patients who had undergone heart transplantation (HT), 50 liver transplantation (LT), and 50 kidney transplantation (KT) and survived at least 12 months after surgery were eligible for this study. All patients underwent the International Classification of Functioning, Disabilities and Health (ICF) questionnaire; ten questions were further applied to those who were employed at the time of the study. X(2) statistics were used to compare working ability evaluation and employment status and for internal comparison among different organ recipients. The employment status was as follows: 92 (61%) patients were in paid employment, 6 (4%) were students or housewives, 36 (24%) were unemployed, and 17 (11%) were retired because of invalidity benefits. According to our fitness evaluation only 4% to 10% of the patients were unfit for any job. When we excluded retired subjects, the X(2) statistics for correlated observations showed a highly significant statistical difference (P < .0001) between unemployed and unfit. As a result of the ICF questionnaire administration, there was a marked difference, although not statistically significant, in the fitness for previously performed jobs between KT and LT recipients (62% and 58%, respectively) and HT recipients (42%). In this cross-sectional study we found a relatively high rate of unemployment as compared with the working ability evaluation by ICF questionnaire and other questions. This may be due to several factors including health status and the possibility of gaining an adequate job. The

Qualitative research creates mountains of words. U.S. federal funding supports mostly structured qualitative research, which is designed to test hypotheses using semiquantitative coding and analysis. This article reports on strategies for planning, organizing, collecting, managing, storing, retrieving, analyzing, and writing about qualitative data so as to most efficiently manage the mountains of words collected in large-scale ethnographic projects. Multiple benefits accrue from this approach. Field expenditures are linked to units of work so productivity is measured, many staff in various locations have access to use and analyze the data, quantitative data can be derived from data that is primarily qualitative, and improved efficiencies of resources are developed.

The thermal properties of many organic extra Virgin Olive Oils (eVOOs) coming from different countries of the world were investigated by Differential Scanning Calorimetry (DSC). This technique, through a series of heating and cooling cycles, provides a specific curve, i.e., a thermogram, which represents the fingerprint of each eVOO sample. In fact, variations due to the different cultivars, geographical origin or chemical composition can be highlighted because they produce changes in the corresponding thermogram. In particular, in this work, we show the results of an unsupervised multivariate statistical analysis applied to the DSC thermograms of many organic eVOOs. This analysis allows us to discriminate the geographical origin of the different studied samples in terms of the peculiar features shown by the melting profiles of the triacylglycerol moieties.

This article describes challenges encountered in applying Jens Rasmussen's Cognitive Work Analysis (CWA) framework to the practice of energy efficiency Monitoring & Targeting (M&T). Eight theoretic issues encountered in the analysis are described with respect to Rasmussen's work and the modeling solutions we adopted. We grappled with how to usefully apply Work Domain Analysis (WDA) to analyze categories of domains with secondary purposes and no ideal grain of decomposition. This difficulty encouraged us to pursue Control Task (ConTA) and Strategies (StrA) analysis, which are under-explored as bases for interface design. In ConTA we found M&T was best represented by two interlinked work functions; one controlling energy, the other maintaining knowledge representations. From StrA, we identified a popular representation-dependent strategy and inferred information required to diagnose faults in system performance and knowledge representation. This article presents and discusses excerpts from our analysis, and outlines their application to diagnosis support tools. Copyright © 2015 Elsevier Ltd. All rights reserved.

Virtual Teams and Human Work Interaction Design - Learning to Work in and Designing for Virtual Teams

NASA Astrophysics Data System (ADS)

Orngreen, Rikke; Clemmensen, Torkil; Pejtersen, Annelise Mark

The boundaries and work processes for how virtual teams interact are undergoing changes, from a tool and stand-alone application orientation, to the use of multiple generic platforms chosen and redesigned to the specific context. These are often at the same time designed both by professional software developers and the individual members of the virtual teams, rather than determined on a single organizational level. There may be no impact of the technology per se on individuals, groups or organizations, as the technology for virtual teams rather enhance situation ambiguity and disrupt existing task-artifact cycles. This ambiguous situation calls for new methods for empirical work analysis and interaction design that can help us understand how organizations, teams and individuals learn to organize, design and work in virtual teams in various networked contexts.

Work-family culture within hospitals: An interdepartmental analysis of employee engagement and retention.

Helping employees balance their work and family needs is increasingly pivotal for attracting, engaging, and retaining key talent in health care. Yet, emerging theory and anecdotal evidence suggest that, within organizations, there is considerable variation between departments or units regarding how employees' lives outside work are supported. Despite top management's efforts to develop a unified organizational work-family culture, departments have a tendency to take on their own culture, norms, and traditions such that some are more supportive than others. We investigate whether more positive work-family cultures improve functioning within hospital departments. We surveyed 680 hospital employees nested within 60 departments at a hospital located in the southeastern United States. Departments with a more (vs. less) positive work-family culture tend to have higher levels of (a) employee engagement, (b) pride in their organization, (c) confidence in management and leadership, and (d) intention to remain with the organization. Our analyses were robust when splitting the sample between clinical (e.g., nurses and physicians) and nonclinical (e.g., office, clerical, and support services) roles. Our study sheds further light on the importance of a positive work-family culture within hospitals. The key to instilling a positive, organization-wide work-family culture may be through a department-by-department focus. Benefits of positive work-family cultures within departments can extend beyond job-related attitudes and can potentially enhance recruitment strategies, improve a hospital's external image to the public, and lead to improvements in patient care and more positive patient experiences.

2005-12-01

A work and power (energy) analysis of the golf swing is presented as a method for evaluating the mechanics of the golf swing. Two computer models were used to estimate the energy production, transfers, and conversions within the body and the golf club by employing standard methods of mechanics to calculate work of forces and torques, kinetic energies, strain energies, and power during the golf swing. A detailed model of the golf club determined the energy transfers and conversions within the club during the downswing. A full-body computer model of the golfer determined the internal work produced at the body joints during the downswing. Four diverse amateur subjects were analyzed and compared using these two models. The energy approach yielded new information on swing mechanics, determined the force and torque components that accelerated the club, illustrated which segments of the body produced work, determined the timing of internal work generation, measured swing efficiencies, calculated shaft energy storage and release, and proved that forces and range of motion were equally important in developing club head velocity. A more comprehensive description of the downswing emerged from information derived from an energy based analysis.

Use of Video Analysis System for Working Posture Evaluations

NASA Technical Reports Server (NTRS)

McKay, Timothy D.; Whitmore, Mihriban

1994-01-01

In a work environment, it is important to identify and quantify the relationship among work activities, working posture, and workplace design. Working posture may impact the physical comfort and well-being of individuals, as well as performance. The Posture Video Analysis Tool (PVAT) is an interactive menu and button driven software prototype written in Supercard (trademark). Human Factors analysts are provided with a predefined set of options typically associated with postural assessments and human performance issues. Once options have been selected, the program is used to evaluate working posture and dynamic tasks from video footage. PVAT has been used to evaluate postures from Orbiter missions, as well as from experimental testing of prototype glove box designs. PVAT can be used for video analysis in a number of industries, with little or no modification. It can contribute to various aspects of workplace design such as training, task allocations, procedural analyses, and hardware usability evaluations. The major advantage of the video analysis approach is the ability to gather data, non-intrusively, in restricted-access environments, such as emergency and operation rooms, contaminated areas, and control rooms. Video analysis also provides the opportunity to conduct preliminary evaluations of existing work areas.

We cannot staff for 'what ifs': the social organization of rural nurses' safeguarding work.

PubMed

MacKinnon, Karen

2012-09-01

Rural nurses play an important role in the provision of maternity care for Canadian women. This care is an important part of how rural nurses safeguard the patients who receive care in small rural hospitals. This study utilized institutional ethnography as an approach for describing rural nursing work and for exploring how nurses' work experiences are socially organized. Rural nurses advocated for safe healthcare environments by ensuring that skilled nurses were available for every shift, day and night, at their local hospital. Rural nurses noted that this work was particularly difficult for the provision of maternity care. This article explores two threads or cues to institutional organization that were identified in our interviews and observations; namely staffing and safety standards, and the need for flexibility in staffing in small rural hospitals. Rural nurses' concerns about ensuring that skilled nurses are available in small rural hospitals do not enter into current management discourses that focus on efficiency and cost savings or find a home within current discourses of patient safety 'competencies'. © 2011 Blackwell Publishing Ltd.

Cross-Validation of the Work Organization Assessment Questionnaire Across Genders: A Study in the Australian Health Care Sector.

PubMed

Karimi, Leila; Karanika-Murray, Maria; Meyer, Denny

2016-03-01

The main aim of this study was to examine the measurement invariance of the Work Organization Assessment Questionnaire (WOAQ) across genders in a group of health care employees, using bifactor modeling. There is a very limited research that uses invariance testing of bifactor models, despite their usefulness. Establishing validity of the WOAQ in this way is important for demonstrating its relevance for both men and women. A bifactor modeling procedure was used here to examine the validity of the WOAQ with a sample of 946 paramedics employed in a large Australian organization in the health care sector. The results of this study show that the WOAQ has good psychometric properties across genders in health care settings. In addition, there were significant mean differences between men and women in their perceptions of "quality of relationships with colleagues," and "reward and recognition." There were no differences between men and women in the remaining factors: "quality of relationships with the management," "quality of relationships with colleagues," and "quality of the physical environment." The use of bifactor modeling to establish the cross-validity of the WOAQ across male and female paramedics adds to evidence for the measure's good psychometric properties. The findings confirm those of previous research that has used higher order confirmatory factor analysis. Moreover, mean differences between men and women were found to be significant in two of the five WOAQ subscales. These findings have practical implications for health care organizations, in terms of assessing work characteristics and developing activities to support the health and well-being of their employees.

Person-organization fit and organizational identification as predictors of positive and negative work-home interactions.

Merecz, Dorota; Andysz, Aleksandra

2014-01-01

The aim of the presented research was to explore the links between complementary and supplementary dimensions of Person-Organization fit (P-O fit), organizational identification (OI) and negative (WHI(-)) versus positive (WHI(+)) work-home interactions. It was assumed that both complementary and supplementary P-O fit and OI were positively related to WHI(+) and negatively to WHI(-). The study was conducted on a large sample of Polish blue and white collar workers. The subjects were interviewed by means of questionnaires measuring: supplementary and complementary dimensions of P-O fit, OI and WHI. General work ability and demographic variables were also controlled in the study, and statistical analysis of ANOVA, pairwise comparison as well as regression were performed. P-O fit and OI differentiated the subjects in terms of WHI. For women supplementary fit was a significant predictor of WHI(-) and explained 12% of its variance, for men it was complementary fit with the number of working days per week and the level of education, which explained 22% of variance. Supplementary fit and OI explained 16% of WHI(+) variance in women; OI, tenure at the main place of employment and the level of education explained 8% of WHI(+) variance in men. It has been proven that not only are the effects of P-O fit and OI limited to the work environment but they also permeate boundaries between work and home and influence private life - good level of P-O fit and good OI play facilitating role in the positive spillover between work and home. Gender differences in the significance and predictive values of P-O fit and OI for WHI were also found. The innovative aspect of the work is the inclusion of P-O fit and OI in the range of significant predictors of work-home interaction. The results can serve as rationale for employers that improvement of P-O fit and employees' organizational identification should be included in work-life balance programs.

In recent years, the interest in the well-being at work has grown considerably, also considering the latest law directives. Several scholars have devoted particular attention to the topic of the work-to-family influence and of social supports, as elements able to affect the perceived well-being. The well-being in health care has to consider the particular nature of work and the relevant relational dimensions that require special attention for the emotional side. The research was promoted by the Committee for Equal Opportunities of a public health organization in the North-West Italy. Referring to the job demands-resources theoretical model, this study investigated the role of organizational and family supports, work-to-family spillover (positive and negative) and family workload as possible determinants of job satisfaction, intended as an indicator of psychological well-being at work. Respondents to the questionnaire are 541 (55% of the total employees), their average age is 43 and they are mostly women (80%). Data analysis showed the central role of supervisors supports, of the co-workers supports and, to a lesser extent, the role of the work-to-family spillover in influencing job satisfaction. Moreover, significant differences between medical and administrative staff were detected. The centrality of supports, especially those of supervisors in determining job satisfaction, is in line with studies indicating that a supportive leadership and a family-friendly culture can facilitate the arise of positive outcomes for both workers and organizations.

Nurse managers are responsible for solving work-related ethical problems to promote a positive ethical culture in healthcare organizations. The aim of this study was to describe the activities that nurse managers use to solve work-related ethical problems. The ultimate aim was to enhance the ethical awareness of all nurse managers. The data for this descriptive cross-sectional survey were analyzed through inductive content analysis and quantification. Participants and research context: The data were collected in 2011 using a questionnaire that included an open-ended question and background factors. Participants were nurse managers working in Finnish healthcare organizations (n = 122). Ethical considerations: Permission for the study was given by the Finnish Association of Academic Managers and Experts of Health Sciences. Nurse managers identified a variety of activities they use to solve work-related ethical problems: discussion (30%), cooperation (25%), work organization (17%), intervention (10%), personal values (9%), operational models (4%), statistics and feedback (4%), and personal examples (1%). However, these activities did not follow any common or systematic model. In the future, nurse managers need a more systematic approach to solve ethical problems. It is important to establish new kinds of ethics structures in organizations, such as a common, systematic ethical decision-making model and an ethics club for nurse manager problems, to support nurse managers in solving work-related ethical problems.

Characterization of polar organic compounds and source analysis of fine organic aerosols in Hong Kong

NASA Astrophysics Data System (ADS)

Li, Yunchun

Organic aerosols, as an important fraction of airborne particulate mass, significantly affect the environment, climate, and human health. Compared with inorganic species, characterization of individual organic compounds is much less complete and comprehensive because they number in thousands or more and are diverse in chemical structures. The source contributions of organic aerosols are far from being well understood because they can be emitted from a variety of sources as well as formed from photochemical reactions of numerous precursors. This thesis work aims to improve the characterization of polar organic compounds and source apportionment analysis of fine organic carbon (OC) in Hong Kong, which consists of two parts: (1) An improved analytical method to determine monocarboxylic acids, dicarboxylic acids, ketocarboxylic acids, and dicarbonyls collected on filter substrates has been established. These oxygenated compounds were determined as their butyl ester or butyl acetal derivatives using gas chromatography-mass spectrometry. The new method made improvements over the original Kawamura method by eliminating the water extraction and evaporation steps. Aerosol materials were directly mixed with the BF 3/BuOH derivatization agent and the extracting solvent hexane. This modification improves recoveries for both the more volatile and the less water-soluble compounds. This improved method was applied to study the abundances and sources of these oxygenated compounds in PM2.5 aerosol samples collected in Hong Kong under different synoptic conditions during 2003-2005. These compounds account for on average 5.2% of OC (range: 1.4%-13.6%) on a carbon basis. Oxalic acid was the most abundant species. Six C2 and C3 oxygenated compounds, namely oxalic, malonic, glyoxylic, pyruvic acids, glyoxal, and methylglyoxal, dominated this suite of oxygenated compounds. More efforts are therefore suggested to focus on these small compounds in understanding the role of oxygenated

Work engagement, work commitment and their association with well-being in health care.

PubMed

Kanste, Outi

2011-12-01

The aim was to examine whether work engagement and work commitment can be empirically discriminated and how they are associated with well-being. The terminology used in literature and in practice is confused by the interchangeable use of these terms. Only few studies, like Hallberg and Schaufeli's study, have examined the relationships between work engagement and work commitment systematically by using empirical data. In this study, the data were gathered via self-reported questionnaire from the healthcare staff working in 14 health centres and four hospitals in Finland. The data consisted of 435 responses. The material was analysed by using structural equation modelling (SEM) and correlations. The items of work engagement and work commitment dimensions (identification with organization, willingness to exert in organization's favour, occupational commitment and job involvement) loaded on their own latent variables in SEM analysis, so the data supported this five-factor model. Work engagement and work commitment dimensions were positively related, sharing between 2 and 33% of their variances. These constructs also displayed different correlations with some indicators of well-being measured as personal accomplishment, psychological well-being, mental resources, internal work motivation and willingness to stay on at work. Work engagement had moderate positive correlation to personal accomplishment (r = 0.68, p < 0.001). Identification with organization (r = 0.40, p < 0.001), willingness to exert in organization's favour (r =0.44, p < 0.001) and occupational commitment (r =0.37, p < 0.001) had low correlations to personal accomplishment. The results support the notion that work engagement can be empirically discriminated from work commitment. They are distinct, yet related constructs that complement each other, describing different aspects of positive attitudes towards work. The results can be utilized in interventions aimed at quality of working life in health care as

Different configurations of organic Rankine cycle (ORC) systems are potential thermodynamic concepts for power generation from low grade heat. The aim of this work is to investigate and optimize the performances of the three main ORC systems configurations: basic ORC, ORC with internal heat exchange (IHE) and regenerative ORC. The evaluation for those configurations was performed using seven working fluids with typical different thermodynamic behaviours (R245fa, R601a, R600a, R227ea, R134a, R1234ze and R1234yf). The optimization has been performed using a genetic algorithm under a comprehensive set of operative parameters such as the fluid evaporating temperature, the fraction of flow rate or the pressure at the steam extracting point in the turbine. Results show that there is no general best ORC configuration for all those fluids. However, there is a suitable configuration for each fluid.

Development and analysis of educational technologies for a blended organic chemistry course

NASA Astrophysics Data System (ADS)

Evans, Michael James

Blended courses incorporate elements of both face-to-face and online instruction. The extent to which blended courses are conducted online, and the proper role of the online components of blended courses, have been debated and may vary. What can be said in general, however, is that online tools for blended courses are typically culled together from a variety of sources, are often very large scale, and may present distractions for students that decrease their utility as teaching tools. Furthermore, large-scale educational technologies may not be amenable to rigorous, detailed study, limiting evaluation of their effectiveness. Small-scale educational technologies run from the instructor's own server have the potential to mitigate many of these issues. Such tools give the instructor or researcher direct access to all available data, facilitating detailed analysis of student use. Code modification is simple and rapid if errors arise, since code is stored where the instructor can easily access it. Finally, the design of a small-scale tool can target a very specific application. With these ideas in mind, this work describes several projects aimed at exploring the use of small-scale, web-based software in a blended organic chemistry course. A number of activities were developed and evaluated using the Student Assessment of Learning Gains survey, and data from the activities were analyzed using quantitative methods of statistics and social network analysis methods. Findings from this work suggest that small-scale educational technologies provide significant learning benefits for students of organic chemistry---with the important caveat that instructors must offer appropriate levels of technical and pedagogical support for students. Most notably, students reported significant learning gains from activities that included collaborative learning supported by novel online tools. For the particular context of organic chemistry, which has a unique semantic language (Lewis

Early blindness alters the spatial organization of verbal working memory.

PubMed

Bottini, Roberto; Mattioni, Stefania; Collignon, Olivier

2016-10-01

Several studies suggest that serial order in working memory (WM) is grounded on space. For a list of ordered items held in WM, items at the beginning of the list are associated with the left side of space and items at the end of the list with the right side. This suggests that maintaining items in verbal WM is performed in strong analogy to writing these items down on a physical whiteboard for later consultation (The Mental Whiteboard Hypothesis). What drives this spatial mapping of ordered series in WM remains poorly understood. In the present study we tested whether visual experience is instrumental in establishing the link between serial order in WM and spatial processing. We tested early blind (EB), late blind (LB) and sighted individuals in an auditory WM task. Replicating previous studies, left-key responses were faster for early items in the list whereas later items facilitated right-key responses in the sighted group. The same effect was observed in LB individuals. In contrast, EB participants did not show any association between space and serial position in WM. These results suggest that early visual experience plays a critical role in linking ordered items in WM and spatial representations. The analogical spatial structure of WM may depend in part on the actual experience of using spatially organized devices (e.g., notes, whiteboards) to offload WM. These practices are largely precluded to EB individuals, who instead rely to mnemonic devices that are less spatially organized (e.g., recordings, vocal notes). The way we habitually organize information in the external world may bias the way we organize information in our WM. Copyright © 2016 Elsevier Ltd. All rights reserved.

Labor market experience, work organization, gender inequalities and health status: results from a prospective analysis of US employed women.

O'Campo, Patricia; Eaton, William W; Muntaner, Carles

2004-02-01

Women's labor force participation has increased dramatically over the past several decades. Although previous research has documented that a wide array of labor market characteristics affect health, more work is needed to understand how women are impacted by gender-specific employment patterns and exposures. We examine a cohort of 659 employed women from the Baltimore Epidemiologic Catchment Area (ECA) study in the USA. Baseline and follow-up data collected 13 years apart are used to identify associations between demographic, labor market, work organization, and occupational gender inequality with four health outcomes: generalized distress, depressive syndrome, anxiety and fair or poor health. We also use gender-specific data on the workplace to create indicators of occupational gender inequality. We found wide gender inequalities in terms of pay and power in this sample of employed women. Financial strain was associated with all of our mental health outcomes with those reporting financial strain having increased odds of distress, depressive syndrome and anxiety for the 13 years prior to the interview. Workplace factors that were found to be associated with the four outcomes included experiencing a promotion or demotion in the 13 years prior to the interview; working at a large firm; and being a professional. Occupations where women compared to men had lower levels of job strain-domestic workers in private households, machine operator and transportation-showed increased risk for anxiety or fair/poor health. Our findings suggest that measuring the complexities of employment including promotion or demotion history, firm characteristics and even occupational gender inequality can yield important information about associations with health among women.

A reaction chamber was coupled to a photoionization aerosol time-of-flight mass spectrometer based on an electron/ion coincidence scheme and applied for on-line analysis of organic and inorganic-organic mixed aerosols using synchrotron tunable vacuum ultraviolet (VUV) photons as the ionization source. In this proof of principle study, both aerosol and gas phase were detected simultaneously but could be differentiated. Present results and perspectives for improvement for this set-up are shown in the study of ozonolysis ([O3] = 0.13-3 ppm) of α-pinene (2-3 ppm), and the uptake of glyoxal upon ammonium sulphate. In this work the ozone concentration was monitored in real time, together with the particle size distributions and chemical composition, the latter taking advantage of the coincidence spectrometer and the tuneability of the synchrotron radiation as a soft VUV ionization source.

Aim of the study was to identify work organization features and workplace hazards associated with sickness presenteeism (SP) among European workers. The study was conducted on data from the European Working Conditions Survey 2010 and included a study population of 30,279 employees. The relationship between work-related factors and SP was assessed through Poisson multivariate robust regression models, adjusting for significant (P < 0.05) individual and work-related characteristics. SP for at least 2 days in the previous year was reported by 35% of the workers. In fully adjusted model, several psychosocial (decision authority, skill discretion, reward, abuse; psychological, cognitive, and emotional demand), and organizational factors (shift work, working with clients, long work hours) were positively associated with SP, whereas job insecurity and exposure to physical factors (lifting or moving people, vibration) decreased SP risk. Our results support the importance of work-related factors, especially psychosocial exposures and organizational features, in determining workers' SP. © 2015 Wiley Periodicals, Inc.

An increasing number of patients become eligible for organ transplants. In the Netherlands, at the level of policy discourse, growing waiting lists are often referred to as a persistent "shortage" of organs, producing a "public health crisis." In this way, organ donation is presented as an ethical, social, and medical necessity. Likewise, policy discourse offers a range of seemingly unambiguous solutions: improving logistical infrastructure at the level of hospitals, developing organizational and legal protocols, as well as public information campaigns. Instead of taking these problem and solution definitions as given, we critically examine the relationship between policy discourse and clinical practice. Based on a historical review, first, we trace the key moments of transformation where organ donation became naturalized in Dutch policy discourse, particularly in its altruistic connotation. Second, based on in-depth interviews with medical professionals, we show how those involved in organ donation continue to struggle with the controversial nature of their clinical practice. More specifically, we highlight their use of different forms of knowledge that underlie clinicians' "transition work": from losing a patient to "gaining" a donor. © The Author(s) 2013.

DuVernet, Amy M; Dierdorff, Erich C; Wilson, Mark A

2015-09-01

Work analysis is fundamental to designing effective human resource systems. The current investigation extends previous research by identifying the differential effects of common design decisions, purposes, and organizational contexts on the data generated by work analyses. The effects of 19 distinct factors that span choices of descriptor, collection method, rating scale, and data source, as well as project purpose and organizational features, are explored. Meta-analytic results cumulated from 205 articles indicate that many of these variables hold significant consequences for work analysis data. Factors pertaining to descriptor choice, collection method, rating scale, and the purpose for conducting the work analysis each showed strong associations with work analysis data. The source of the work analysis information and organizational context in which it was conducted displayed fewer relationships. Findings can be used to inform choices work analysts make about methodology and postcollection evaluations of work analysis information. (c) 2015 APA, all rights reserved).

2018-10-30

An authentication procedure for differentiating between organic and non-organic cattle production on the basis of analysis of serum samples has been developed. For this purpose, the concentrations of fourteen mineral elements (As, Cd, Co, Cr, Cu, Fe, Hg, I, Mn, Mo, Ni, Pb, Se and Zn) in 522 serum samples from cows (341 from organic farms and 181 from non-organic farms), determined by inductively coupled plasma spectrometry, were used. The chemical information provided by serum analysis was employed to construct different pattern recognition classification models that predict the origin of each sample: organic or non-organic class. Among all classification procedures considered, the best results were obtained with the decision tree C5.0, Random Forest and AdaBoost neural networks, with hit levels close to 90% for both production types. The proposed method, involving analysis of serum samples, provided rapid, accurate in vivo classification of cattle according to organic and non-organic production type.

Organizational features can affect how staff view their quality of work life. Determining staff perceptions about quality of work life is an important consideration for employers interested in improving employee job satisfaction. The purpose of this study was to identify organization specific predictors of job satisfaction within a health care system that consisted of six independent health care organizations. 5,486 full, part and causal time (non-physician) staff on active payroll within six organizations (2 community hospitals, 1 community hospital/long-term care facility, 1 long-term care facility, 1 tertiary care/community health centre, and 1 visiting nursing agency) located in five communities in Central West Ontario, Canada were asked to complete a 65-item quality of work life survey. The self-administered questionnaires collected staff perceptions of: co-worker and supervisor support; teamwork and communication; job demands and decision authority; organization characteristics; patient/resident care; compensation and benefits; staff training and development; and impressions of the organization. Socio-demographic data were also collected. Depending on the organization, between 15 and 30 (of the 40 potential predictor) variables were found to be statistically associated with job satisfaction (univariate analyses). Logistic regression analyses identified the best predictors of job satisfaction and these are presented for each of the six organizations and for all organizations combined. The findings indicate that job satisfaction is a multidimensional construct and although there appear to be some commonalities across organizations, some predictors of job satisfaction appear to be organization and context specific.

2017-12-12

The aim of this study was to examine how the developed taxonomy of cognitive work analysis (CWA) can be applied in combination with statistical analysis regarding different sociotechnical categories. This study applied a combination of quantitative and qualitative methodologies. Workers (n = 120) and managers (n = 85) in the chemical industry were asked in a questionnaire how different occupational safety and health (OSH) measures were being implemented. The exploration of the qualitative CWA taxonomy consisted of an analysis of the following topics: (a) work domain; (b) control task; (c) strategies; (d) social organization and cooperation; (e) worker competencies. The following hypotheses were supported - activities of the management had positive impacts on the aggregated variables: near-accident investigation and instructions (H 1 ); OSH training (H 2 ); operations, technical processes and safe use of chemicals (H 3 ); use of personal protective equipment (H 4 ); measuring, follow-up and prevention of major accidents (H 5 ). The CWA taxonomy was applied in mixed methods when testing H 1 -H 5 . A special approach is to analyze the work demands of complex sociotechnical systems with the taxonomy of CWA. In problem-solving, the CWA taxonomy should seek to capitalize on the strengths and minimize the limitations of safety performance.

This paper presents the Ergonomic Work Analysis method in a Brazilian Dentist's office. Through the study, the constraints and the strategies in avoiding them were identified. It was found that dentists hardly use the position most indicated by the International Organization for Standardization (ISO) and the Federation Dentaire Internacionale (FDI) for both the patient and the dentist, which is respectively supine and 9 o'clock, due to the limited space and layout. Five types of treatments performed by the professional have been studied. The frequency and duration of actions in these treatments were accounted for and the standard positions adopted were identified. The AET was found to be a very suitable method to grasp the dentist's activity and build a point of view of the profession, which is characterized as: stressful, perfectionist and restrictive. Time management is presented as an important strategy to control the tension arising from performing the treatments.

Ward, Deborah J; Furber, Christine; Tierney, Stephanie; Swallow, Veronica

2013-11-01

To demonstrate Framework Analysis using a worked example and to illustrate how criticisms of qualitative data analysis including issues of clarity and transparency can be addressed. Critics of the analysis of qualitative data sometimes cite lack of clarity and transparency about analytical procedures; this can deter nurse researchers from undertaking qualitative studies. Framework Analysis is flexible, systematic, and rigorous, offering clarity, transparency, an audit trail, an option for theme-based and case-based analysis and for readily retrievable data. This paper offers further explanation of the process undertaken which is illustrated with a worked example. Data were collected from 31 nursing students in 2009 using semi-structured interviews. The data collected are not reported directly here but used as a worked example for the five steps of Framework Analysis. Suggestions are provided to guide researchers through essential steps in undertaking Framework Analysis. The benefits and limitations of Framework Analysis are discussed. Nurses increasingly use qualitative research methods and need to use an analysis approach that offers transparency and rigour which Framework Analysis can provide. Nurse researchers may find the detailed critique of Framework Analysis presented in this paper a useful resource when designing and conducting qualitative studies. Qualitative data analysis presents challenges in relation to the volume and complexity of data obtained and the need to present an 'audit trail' for those using the research findings. Framework Analysis is an appropriate, rigorous and systematic method for undertaking qualitative analysis. © 2013 Blackwell Publishing Ltd.

In modern society, many workers are stressed. Supervisors' support or behavior can affect the emotional or psychological part of the worker. The purpose of this study is to investigate the effect of supervisor's behavior on worker's stress. The study included 19,272 subjects following the assignment of weighted values to workers other than soldiers using data from the Fourth Korean Working Condition Survey. Supervisors' behavior was measured using 5 items: "supervisor feedback regarding work," "respectful attitude," "good conflict-resolution ability," "good work-related planning and organizational ability," and the encouragement of participation in important decision making. Job stress was measured using 1 item: "I experience stress at work." Multiple logistic regression analysis was performed to examine the effects of supervisors' behavioral, general, occupational, and psychosocial characteristics on job stress in workers. Organizational characteristics associated with supervisors' behavior were also analyzed. The results showed that supervisors' provision of feedback regarding work increased workers' job stress (OR = 1.329, 95% CI = 1.203 ~ 1.468). When a supervisor respect workers (OR = 0.812, 95% CI = 0.722 ~ 0.913) or good at planning and organizing works (OR = 0.816, 95% CI: 0.732 ~ 0.910), workers' job stress decreased. In particular, the two types of supervisor behaviors, other than feedback regarding work, were high in private-sector organizations employing less than 300 employees. Supervisors' behavior influenced job stress levels in workers. Therefore, it is necessary to increase education regarding the effects of supervisors' behavior on job stress, which should initially be provided in private-sector organizations with up to 300 employees.

Organic tracer-based source analysis of PM2.5 organic and elemental carbon: A case study at Dongguan in the Pearl River Delta, China

Organic carbon (OC) and elemental carbon (EC) are major constituents of PM2.5 and their source apportionment remains a challenging task due to the great diversity of their sources and lack of source-specific tracer data. In this work, sources of OC and EC are investigated using positive matrix factorization (PMF) analysis of PM2.5 chemical composition data, including major ions, OC, EC, elements, and organic molecular source markers, for a set of 156 filter samples collected over three years from 2010 to 2012 at Dongguan in the Pearl River Delta, China. The key organic tracers include levoglucosan, mannosan, hopanes, C27-C33n-alkanes, and polycyclic aromatic hydrocarbons (PAHs). Using these species as input for the PMF model, nine factors were resolved. Among them, biomass burning and coal combustion were significant sources contributing 15-17% of OC and 24-30% and 34-35% of EC, respectively. Industrial emissions and ship emissions, identified through their characteristic metal signatures, contributed 16-24% and 7-8% of OC and 8-11% and 16-17% of EC, respectively. Vehicle exhaust was a less significant source, accounting for 3-4% of OC and 5-8% of EC. Secondary OC, taken to be the sum of OC present in secondary sulfate and nitrate formation source factors, made up 27-36% of OC. Plastic burning, identified through 1,3,5-triphenylbenzene as a tracer, was a less important source for OC(≤4%) and EC (5-10%), but a significant source for PAHs at this site. The utility of organic source tracers was demonstrated by comparing PMF runs with different combinations of organic tracers removed from the input species list. Levoglucosan and mannosan were important additions to distinguish biomass burning from coal combustion by reducing collinearity among source profiles. Inclusion of hopanes and 1,3,5-triphenylbenzene was found to be necessary in resolving the less significant sources vehicle exhaust and plastic burning. Inclusion of C27-C33n-alkanes and PAHs can influence the

First, to document the prevalence of corridor occupations and conversations among the staff of a hospital clinic, and their main features. Second, to examine the activities accomplished through corridor conversations and their interactional organization. Despite extensive research on mobility in hospital work, we still know fairly little about the prevalence and features of hospital staff corridor conversations and how they are organized. We conducted a study combining descriptive statistical analysis and multimodal conversation analysis of video recordings of staff corridor practices in a hospital outpatient clinic in Switzerland. In 2012, we collected 59 hours of video recordings in a corridor of a hospital clinic. We coded and statistically analysed the footage that showed the clinic staff exclusively. We also performed qualitative multimodal conversation analysis on a selection of the recorded staff conversations. Corridor occupations by the clinic staff are frequent and brief and rarely involve stops. Talk events (which include self-talk, face-to-face conversations and telephone conversations) during occupations are also brief and mobile, overwhelmingly focus on professional topics and are particularly frequent when two or more staff members occupy the corridor. The conversations present several interactional configurations and comprise an array of activities consequential to the provision of care and work organization. These practices are related to the fluid work organization of a spatially distributed team in a fast-paced, multitasking environment and should be taken into consideration in any undertaking aimed at improving hospital units' functioning. © 2015 John Wiley & Sons Ltd.

Spatially resolved organic analysis of the Allende meteorite

The distribution of polycyclic aromatic hydrocarbons (PAHs) in the Allende meteorite has been probed with two-step laser desorption/laser multiphoton ionization mass spectrometry. This method allows direct in situ analysis with a spatial resolution of 1 sq mm or better of selected organic molecules. Spectra from freshly fractured interior surfaces of the meteorite show that PAH concentrations are locally high compared to the average concentrations found by wet chemical analysis of pulverized samples. The data suggest that the PAHs are primarily associated with the fine-grained matrix, where the organic polymer occurs. In addition, highly substituted PAH skeletons were observed. Interiors of individual chondrules were devoid of PAHs at the detection limit (about 0.05 ppm).

Vaccination versus treatment of influenza in working adults: a cost-effectiveness analysis.

Rothberg, Michael B; Rose, David N

2005-01-01

To determine the cost-effectiveness of influenza vaccination, antiviral therapy, or no intervention for healthy working adults, accounting for annual variation in vaccine efficacy. We conducted a cost-effectiveness analysis based on published clinical trials of influenza vaccine and antiviral drugs, incorporating 10 years of surveillance data from the World Health Organization. We modeled influenza vaccination, treatment of influenza-like illness with antiviral drugs, or both, as compared with no intervention, targeting healthy working adults under age 50 years in the general community or workplace. Outcomes included costs, illness days, and quality-adjusted days gained. In the base case analysis, the majority of costs incurred for all strategies were related to lost productivity from influenza illness. The least expensive strategy varied from year to year. For the 10-year period, antiviral therapy without vaccination was associated with the lowest overall costs (234 US dollars per person per year). Annual vaccination cost was 239 US dollars per person, and was associated with 0.0409 quality-adjusted days saved, for a marginal cost-effectiveness ratio of 113 US dollars per quality-adjusted day gained or 41,000 US dollars per quality-adjusted life-year saved compared with antiviral therapy. No intervention was the most expensive and least effective option. In sensitivity analyses, lower vaccination costs, higher annual probabilities of influenza, and higher numbers of workdays lost to influenza made vaccination more cost-effective than treatment. If vaccination cost was less than 16 US dollars or time lost from work exceeded 2.4 days per episode of influenza, then vaccination was cost saving compared with all other strategies. Influenza vaccination for healthy working adults is reasonable economically, and under certain circumstances is cost saving. Antiviral therapy is consistently cost saving.

Parametric and working fluid analysis of a combined organic Rankine-vapor compression refrigeration system activated by low-grade thermal energy.

The potential use of many common hydrofluorocarbons and hydrocarbons as well as new hydrofluoroolefins, i.e. R1234yf and R1234ze(E) working fluids for a combined organic Rankine cycle and vapor compression refrigeration (ORC-VCR) system activated by low-grade thermal energy is evaluated. The basic ORC operates between 80 and 40 °C typical for low-grade thermal energy power plants while the basic VCR cycle operates between 5 and 40 °C. The system performance is characterized by the overall system coefficient of performance (COPS) and the total mass flow rate of the working fluid for each kW cooling capacity ([Formula: see text]). The effects of different working parameters such as the evaporator, condenser, and boiler temperatures on the system performance are examined. The results illustrate that the maximum COPS values are attained using the highest boiling candidates with overhanging T-s diagram, i.e. R245fa and R600, while R600 has the lowest [Formula: see text] under the considered operating conditions. Among the proposed candidates, R600 is the best candidate for the ORC-VCR system from the perspectives of environmental issues and system performance. Nevertheless, its flammability should attract enough attention. The maximum COPS using R600 is found to reach up to 0.718 at a condenser temperature of 30 °C and the basic values for the remaining parameters.

ABSTRACT OBJECTIVE Tto identify factors associated with unintentional sleep at work of airline pilots. METHODS This is a cross-sectional epidemiological study conducted with 1,235 Brazilian airline pilots, who work national or international flights. Data collection has been performed online. We carried out a bivariate and multiple logistic regression analysis, having as dependent variable unintentional sleep at work. The independent variables were related to biodemographic data, characteristics of the work, lifestyle, and aspects of sleep. RESULTS The prevalence of unintentional sleep while flying the airplane was 57.8%. The factors associated with unintentional sleep at work were: flying for more than 65 hours a month, frequent technical delays, greater need for recovery after work, work ability below optimal, insufficient sleep, and excessive sleepiness. CONCLUSIONS The occurrence of unintentional sleep at work of airline pilots is associated with factors related to the organization of the work and health. PMID:28678902

long periods of stability punctuated by shorts bursts of 'reorganization,' business enterprises will come to realize that their very survival depends upon their being in a state of continuous organization. The implications of the new organization with respect to how companies approach the planning, design, and management of the technology infrastructure that enables individual learning, self-management, and continuous orgsnization, are both numerous and far-reaching. As part of this technology infrastructure, the white-collar workplace exists in the form it does today as a direct result of management's beliefs about how time, space, and tools ought to be organized and managed in order to accomplish useful intellectual work. Obviously, if these beliefs change radically, as both the new science and the new management thinking suggest is about to happen, then it is almost inevitable that the form and function of the white-collar workplace will change radically, as well. Will there even be a white-collar workplace in the 21st century, in the sense of purpose-built facilities designed to support the co-location of large numbers of white-collar workers? Only time will tell. However, the leading indicators seem to suggest that, as the old saying goes, 'We ain't seen nothin' yet!'

Even though organic light-emitting device (OLED) technology has evolved to a point where it is now an important competitor to liquid crystal displays (LCDs), further scientific efforts devoted to the design, engineering and fabrication of OLEDs are required for complete commercialization of this technology. Along these lines, the present work reviews the essentials of OLED technology putting special focus on the general working principle of single and multilayer OLEDs, fluorescent and phosphorescent emitter materials as well as transfer processes in host materials doped with phosphorescent dyes. Moreover, as a prototypical example of phosphorescent emitter materials, a brief discussion of homo- and heteroleptic iridium(III) complexes is enclosed concentrating on their synthesis, photophysical properties and approaches for realizing iridium based phosphorescent polymers.

Douvartzides, S.; Karmalis, I.

2016-11-01

Organic Rankine cycle technology is capable to efficiently convert low-grade heat into useful mechanical power. In the present investigation such a cycle is used for the recovery of heat from the exhaust gases of a four stroke V18 MAN 51/60DF internal combustion engine power plant operating with natural gas. Design is focused on the selection of the appropriate working fluid of the Rankine cycle in terms of thermodynamic, environmental and safety criteria. 37 candidate fluids have been considered and all Rankine cycles examined were subcritical. The thermodynamic analysis of all fluids has been comparatively undertaken and the effect of key operation conditions such as the evaporation pressure and the superheating temperature was taken into account. By appropriately selecting the working fluid and the Rankine cycle operation conditions the overall plant efficiency was improved by 5.52% and fuel consumption was reduced by 12.69%.

Physics-based deformable organisms for medical image analysis

NASA Astrophysics Data System (ADS)

Hamarneh, Ghassan; McIntosh, Chris

2005-04-01

Previously, "Deformable organisms" were introduced as a novel paradigm for medical image analysis that uses artificial life modelling concepts. Deformable organisms were designed to complement the classical bottom-up deformable models methodologies (geometrical and physical layers), with top-down intelligent deformation control mechanisms (behavioral and cognitive layers). However, a true physical layer was absent and in order to complete medical image segmentation tasks, deformable organisms relied on pure geometry-based shape deformations guided by sensory data, prior structural knowledge, and expert-generated schedules of behaviors. In this paper we introduce the use of physics-based shape deformations within the deformable organisms framework yielding additional robustness by allowing intuitive real-time user guidance and interaction when necessary. We present the results of applying our physics-based deformable organisms, with an underlying dynamic spring-mass mesh model, to segmenting and labelling the corpus callosum in 2D midsagittal magnetic resonance images.

The effect of lean production on conditions for learning is debated. This study aimed to investigate how tools inspired by lean production (standardization, resource reduction, visual monitoring, housekeeping, value flow analysis) were associated with an innovative learning climate and with collective dispersion of ideas in organizations, and whether decision latitude contributed to these associations. A questionnaire was sent out to employees in public, private, production and service organizations (n = 4442). Multilevel linear regression analyses were used. Use of lean tools and decision latitude were positively associated with an innovative learning climate and collective dispersion of ideas. A low degree of decision latitude was a modifier in the association to collective dispersion of ideas. Lean tools can enable shared understanding and collective spreading of ideas, needed for the development of work processes, especially when decision latitude is low. Value flow analysis played a pivotal role in the associations. Copyright © 2014 Elsevier Ltd and The Ergonomics Society. All rights reserved.

To screen and identify safe micro-organisms used during Douchi fermentation, and verify the feasibility of producing high-quality Douchi using these identified micro-organisms. PCR-denaturing gradient gel electrophoresis (DGGE) and automatic amino-acid analyser were used to investigate the microbial diversity and free amino acids (FAAs) content of 10 commercial Douchi samples. The correlations between microbial communities and FAAs were analysed by statistical analysis. Ten strains with significant positive correlation were identified. Then an experiment on Douchi fermentation by identified strains was carried out, and the nutritional composition in Douchi was analysed. Results showed that FAAs and relative content of isoflavone aglycones in verification Douchi samples were generally higher than those in commercial Douchi samples. Our study indicated that fungi, yeasts, Bacillus and lactic acid bacteria were the key players in Douchi fermentation, and with identified probiotic micro-organisms participating in fermentation, a higher quality Douchi product was produced. This is the first report to analyse and confirm the key micro-organisms during Douchi fermentation by statistical analysis. This work proves fermentation micro-organisms to be the key influencing factor of Douchi quality, and demonstrates the feasibility of fermenting Douchi using identified starter micro-organisms. © 2015 The Society for Applied Microbiology.

Comelli, Daniela; D'Andrea, Cosimo; Valentini, Gianluca; Cubeddu, Rinaldo; Colombo, Chiara; Toniolo, Lucia

2004-04-01

A system for advanced fluorescence investigation of works of art has been assembled and integrated in a characterization procedure that allows one to localize and identify organic compounds that are present in artworks. At the beginning of the investigation, fluorescence lifetime imaging and spectroscopy address a selective microsampling of the artwork. Then analytical measurements of microsamples identify the chemical composition of the materials under investigation. Finally, on the basis of fluorescence lifetime and amplitude maps, analytical data are extended to the whole artwork. In such a way, information on the spatial distribution of organic materials can be inferred. These concepts have been successfully applied in an extensive campaign for analysis of Renaissance fresco paintings in Castiglione Olona, Italy. Residue of various types of glue and stucco left from a restoration carried out in the early 1970s was localized and classified. Insight into the technique used by the painter to make gilded reliefs was also obtained.

In response to need: an analysis of social work roles over time.

In this qualitative research synthesis, interviews with 22 early health-related social workers were reexamined to identify themes that emerged when these social workers discussed the roles and goals of their work. Those interviews, with colleagues of Ida M. Cannon and those leaders in the next generation of social workers who had practiced during the first half of the 20th century, were conducted in 1976. For this study, the themes that emerged from the original interview data as social workers' responses to perceived needs were then compared with data consisting of 80 cases, drawn from four more recent casebooks (1982, 1989, 1996, 2010), that followed a framework of practice in context. The comparison demonstrated that themes remain consistent over time and include responses to needs created by wars, due to new and underserved populations, created by public health crises, created by technological advances, experienced by organizations, and resulting from economic and policy issues, as well as needs of clients. Analysis also suggests that caution is in order to avoid being co-opted by organizations and others in power at the cost of the profession's social justice mission and ethical imperatives.

There has been concern expressed by the UK regulator, the Health & Safety Executive, regarding the management of occupation dose for healthcare radiation workers who work across multiple organizations. In response to this concern, the British Institute of Radiology led a working group of relevant professional bodies to develop guidance in this area. The guidance addresses issues of general system management that would apply to all personal dosimetry systems, regardless of whether or not the workers within that system work across organizational boundaries, along with exploring efficient strategies to comply with legislation where those workers do indeed work across organizational boundaries. For those specific instances, the guidance discusses both system requirements to enable organizations to co-operate (Ionising Radiation Regulations 1999 Regulation 15), as well as specific instances of staff exposure. This is broken down into three categories-low, medium and high risk. A suggested approach to each is given to guide employers and their radiation advisers in adopting sensible strategies for the monitoring of their staff and the subsequent sharing of dosimetry data to ensure overall compliance with both dose limits and optimization requirements.

Using cognitive work analysis to explore activity allocation within military domains.

Jenkins, D P; Stanton, N A; Salmon, P M; Walker, G H; Young, M S

2008-06-01

Cognitive work analysis (CWA) is frequently advocated as an approach for the analysis of complex socio-technical systems. Much of the current CWA literature within the military domain pays particular attention to its initial phases; work domain analysis and contextual task analysis. Comparably, the analysis of the social and organisational constraints receives much less attention. Through the study of a helicopter mission planning system software tool, this paper describes an approach for investigating the constraints affecting the distribution of work. The paper uses this model to evaluate the potential benefits of the social and organisational analysis phase within a military context. The analysis shows that, through its focus on constraints, the approach provides a unique description of the factors influencing the social organisation within a complex domain. This approach appears to be compatible with existing approaches and serves as a validation of more established social analysis techniques. As part of the ergonomic design of mission planning systems, the social organisation and cooperation analysis phase of CWA provides a constraint-based description informing allocation of function between key actor groups. This approach is useful because it poses questions related to the transfer of information and optimum working practices.

Managing breastfeeding and work: a Foucauldian secondary analysis.

PubMed

Payne, Deborah; Nicholls, David A

2010-08-01

This paper is a report of a secondary analysis of the experiences of employed breastfeeding mothers. Health promotion policies exhort mothers to feed their infants breastmilk exclusively for the first 6 months and partially until the age of 2 years. More mothers are returning to paid employment less than a year after having a baby. Combining breastfeeding and paid work is an issue for nursing and midwifery as predominantly female professions caring for women and their children. Foucauldian discourse analysis was used for a secondary analysis of interviews performed in 2005 with 20 women who continued to breastfeed on their return to work. The discursive positions and disciplinary practices were identified and analysed. Combining breastfeeding and paid work required negotiating the positions of good mother and good worker. Being a good mother conferred health benefits on infants. Being a good worker required the mothers to constrain their breastfeeding practices. The practices performed by the mothers involved stockpiling breastmilk, maintaining milk supply, preparing the baby ready for absence, making sacrifices and remaining silent and invisible as a breastfeeding worker. Breastfeeding workers have the potential to threaten the focus of the workplace. They discipline themselves to minimize their disruptive potential. Such strategies serve to maintain the marginalization of breastfeeding in the workplace and to keep women's efforts to continue breastfeeding invisible. The work of breastfeeding workers needs to be better recognized and supported.

These all have to be mapped at some point to human performance requirements. The EBR-II results will be used as a baseline that will be extrapolated in the extended Cognitive Work Analysis phase to the analysis of a selected advanced sodium-cooled SMR design as a way to establish non-conventional operational concepts. The Work Domain Analysis results achieved during this phase have not only established an organizing and analytical framework for describing existing sociotechnical systems, but have also indicated that the method is particularly suited to the analysis of prospective and immature designs. The results of the EBR-II Work Domain Analysis have indicated that the methodology is scientifically sound and generalizable to any operating environment.« less

Analyzing huge amounts of data becomes essential in the era of Big Data, where databases are populated with hundreds of Gigabytes that must be processed to extract knowledge. Hence, classical algorithms must be adapted towards distributed computing methodologies that leverage the underlying computational power of these platforms. Here, a parallel, scalable, and optimized design for self-organized maps (SOM) is proposed in order to analyze massive data gathered by the spectrophotometric sensor of the European Space Agency (ESA) Gaia spacecraft, although it could be extrapolated to other domains. The performance comparison between the sequential implementation and the distributed ones based on Apache Hadoop and Apache Spark is an important part of the work, as well as the detailed analysis of the proposed optimizations. Finally, a domain-specific visualization tool to explore astronomical SOMs is presented.

The relationship among work-family conflict and enhancement, organizational work-family culture, and work outcomes for older working women.

2007-10-01

This article examines the relationship among work-family conflict and enhancement, organizational work-family culture, and four work outcomes for 489 working women over the age of 50. Survey results from two U.S. health care organizations and one U.S. financial services organization indicate that older working women experience differing amounts of work-to-family conflict, family-to-work conflict, work-to-family enhancement, and family-to-work enhancement. Hypotheses relating organizational work-family culture to work-family conflict and enhancement were partially supported, and hypotheses relating conflict and enhancement to four work outcomes were partially supported. Work-to-family conflict and work-to-family enhancement partially mediate the relationship between organizational work-family culture and selected work outcomes. Implications for theory and practice, limitations of this study, and directions for future research are also presented.

Earthworm Effects without Earthworms: Inoculation of Raw Organic Matter with Worm-Worked Substrates Alters Microbial Community Functioning

PubMed Central

Aira, Manuel; Domínguez, Jorge

2011-01-01

Background Earthworms are key organisms in organic matter decomposition because of the interactions they establish with soil microorganisms. They enhance decomposition rates through the joint action of direct effects (i.e. effects due to direct earthworm activity such as digestion, burrowing, etc) and indirect effects (i.e. effects derived from earthworm activities such as cast ageing). Here we test whether indirect earthworm effects affect microbial community functioning in the substrate, as when earthworms are present (i. e., direct effects). Methodology/Principal Findings To address these questions we inoculated fresh organic matter (pig manure) with worm-worked substrates (vermicompost) produced by three different earthworm species. Two doses of each vermicompost were used (2.5 and 10%). We hypothesized that the presence of worm-worked material in the fresh organic matter will result in an inoculum of different microorganisms and nutrients. This inoculum should interact with microbial communities in fresh organic matter, thus promoting modifications similar to those found when earthworms are present. Inoculation of worm-worked substrates provoked significant increases in microbial biomass and enzyme activities (β-glucosidase, cellulase, phosphatase and protease). These indirect effects were similar to, although lower than, those obtained in pig manure with earthworms (direct and indirect earthworm effects). In general, the effects were not dose-dependent, suggesting the existence of a threshold at which they were triggered. Conclusion/Significance Our data reveal that the relationships between earthworms and microorganisms are far from being understood, and suggest the existence of several positive feedbacks during earthworm activity as a result of the interactions between direct and indirect effects, since their combination produces stronger modifications to microbial biomass and enzyme activity.

Specific physical activities or working conditions are suspected for increasing the risk of preterm birth (PTB). The aim of this meta-analysis is to review and summarize the pre-existing evidence on the effect of shift work or long working hours on the risk of PTB. We conducted a systematic search in MEDLINE and EMBASE (1990-2013) for observational and intervention studies with original data. We only included articles that met our specific criteria for language, exposure, outcome, data collection and original data that were of at least of moderate quality. The data of the included studies were pooled. Eight high-quality studies and eight moderate-quality studies were included in the meta-analysis. In these studies, no clear or statistically significant relationship between shift work and PTB was found. The summary estimate OR for performing shift work during pregnancy and the risk of PTB were 1.04 (95% CI 0.90-1.20). For long working hours during pregnancy, the summary estimate OR was 1.25 (95% CI 1.01-1.54), indicating a marginally statistically significant relationship but an only slightly elevated risk. Although in many of the included studies a positive association between long working hours and PTB was seen this did reach only marginal statistical significance. In the studies included in this review, working in shifts or in night shifts during pregnancy was not significantly associated with an increased risk for PTB. For both risk factors, due to the lack of high-quality studies focusing on the risks per trimester, in particular the third trimester, a firm conclusion about an association cannot be stated.

Gas-liquid chromatography in lunar organic analysis.

NASA Technical Reports Server (NTRS)

Gehrke, C. W.

1972-01-01

Gas-liquid chromatography (GLC) is a powerful and sensitive method for the separation and detection of organic compounds at nanogram levels. The primary requirement for successful analyses is that the compounds of interest must be volatile under the chromatographic conditions employed. Nonvolatile organic compounds must be converted to volatile derivatives prior to analysis. The derivatives of choice must be both amenable to chromatographic separation and be relatively stable. The condition of volatility necessitates the development of efficient derivatization reactions for important groups of compounds as amino acids, carbohydrates, nucleosides, etc. Trimethylsilylation and trifluoroacetylation represent specific areas of recent prominence. Some relevant practical aspects of GLC are discussed.

The experiential claims of nine people who stuttered were examined with the purpose of determining the impact of stuttering on their work lives and to further examine what meaning they derive from these experiences. Six male and three female participants aged 29-61 years (mean age, 41.4) who stuttered were interviewed and verbatim interview transcripts were analyzed using interpretative phenomenological analysis. Credibility was established by way of member checking, researcher comparison with only consensual themes and interpretations presented in the final analysis. Four Superordinate themes, "stuttering is always there; stuttering at work reveals a problem; stuttering limits communication; and stuttering limits occupational progression" were distilled by descriptive and interpretative treatment of the interview transcripts. The interpretative level of analysis identified self-stigma as central to the meaning derived from these experiences. Participants' expectation of stigmatizing public attitudes, together with their own self-validation of such attitudes perpetuated diminished feelings about self-esteem and self-efficacy. Fear of negative evaluation may be heightened in the work context and might mediate feelings of self-stigma in this context. Superordinate themes and their subthemes indicate that stuttering is problematic at work by way of perpetuating in the PWS an expectation of negative evaluation by others. Findings implicate issues of self-stigma as generating feelings of self-doubt and self-reproach in PWS in the workplace. The development and effects of self-stigma in PWS have broader implications than the workplace context alone and further examination of the issues of self-stigma in stuttering is recommended. At the end of this activity the reader will be able to: (a) describe how stuttering might affect workplace experiences; (b) describe the impact of stuttering on communication in the work context; (c) describe how qualitative methods can provide

Hydrogen Isotope Measurements of Organic Acids and Alcohols by Pyrolysis-GC-MS-TC-IRMS: Application to Analysis of Experimentally Derived Hydrothermal Mineral-Catalyzed Organic Products

2012-01-01

We report results of experiments to measure the H isotope composition of organic acids and alcohols. These experiments make use of a pyroprobe interfaced with a GC and high temperature extraction furnace to make quantitative H isotope measurements. This work compliments our previous work that focused on the extraction and analysis of C isotopes from the same compounds [1]. Together with our carbon isotope analyses our experiments serve as a "proof of concept" for making C and H isotope measurements on more complex mixtures of organic compounds on mineral surfaces in abiotic hydrocarbon formation processes at elevated temperatures and pressures. Our motivation for undertaking this work stems from observations of methane detected within the Martian atmosphere [2-5], coupled with evidence showing extensive water-rock interaction during Mars history [6-8]. Methane production on Mars could be the result of synthesis by mineral surface-catalyzed reduction of CO2 and/or CO by Fischer-Tropsch Type (FTT) reactions during serpentization [9,10]. Others have conducted experimental studies to show that FTT reactions are plausible mechanisms for low-molecular weight hydrocarbon formation in hydrothermal systems at mid-ocean ridges [11-13]. Our H isotope measurements utilize an analytical technique combining Pyrolysis-Gas Chromatograph-Mass Spectrometry-High Temperature Conversion-Isotope Ratio Mass Spectrometry (Py-GC-MS-TC-IRMS). This technique is designed to carry a split of the pyrolyzed GC-separated product to a Thermo DSQII quadrupole mass spectrometer as a means of making qualitative and semi-quantitative compositional measurements of separated organic compounds, therefore both chemical and isotopic measurements can be carried out simultaneously on the same sample.

High-Resolution Electrospray Ionization Mass Spectrometry Analysis of Water- Soluble Organic Aerosols Collected with a Particle into Liquid Sampler

Bateman, Adam P.; Nizkorodov, Serguei; Laskin, Julia

2010-10-01

This work demonstrates the utility of a particle-into-liquid sampler (PILS) a technique traditionally used for identification of inorganic ions present in ambient or laboratory aerosols for the analysis of water soluble organic aerosol (OA) using high resolution electrospray ionization mass spectrometry (HR ESI-MS). Secondary organic aerosol (SOA) was produced from 0.5 ppm mixing ratios of limonene and ozone in a 5 m3 Teflon chamber. SOA was collected simultaneously using a traditional filter sampler and a PILS. The filter samples were later extracted with either water or acetonitrile, while the aqueous PILS samples were analyzed directly. In terms of peak intensities,more » types of detectable compounds, average O:C ratios, and organic mass to organic carbon ratios, the resulting high resolution mass spectra were essentially identical for the PILS and filter based samples. SOA compounds extracted from both filter/acetonitrile extraction and PILS/water extraction accounted for >95% of the total ion current in ESI mass spectra. This similarity was attributed to high solubility of limonene SOA in water. In contrast, significant differences in detected ions and peak abundances were observed for pine needle biomass burning organic aerosol (BBOA) collected with PILS and filter sampling. The water soluble fraction of BBOA is considerably smaller than for SOA, and a number of unique peaks were detectable only by the filter/acetonitrile method. The combination of PILS collection with HR-ESI-MS analysis offers a new approach for molecular analysis of the water-soluble organic fraction in biogenic SOA, aged photochemical smog, and BBOA.« less

Transgressive ethics: Professional work ethics as a perspective on ‘aggressive organ harvesting’

PubMed Central

Jensen, Anja MB

2013-01-01

Occasionally brain-dead organ donors go into cardiac arrest before reaching the operating theater. In such cases, the needed resuscitation of the potential donor stimulates a range of concerns among the responsible staff. If the intensive care unit staff are going to carry out the organ retrieval, they must rush in with demanding treatment measures such as defibrillation shock and cardiac massage that may break breast bones and make the donor vomit. Such treatment measures conflict with widespread ideals of tranquility in donor care and yet they are currently under consideration in Danish intensive care units. Why is this type of ‘aggressive organ harvesting’, as it is sometimes called, considered a likely development, even to the extent that the interviewed health professionals request a policy prescribing procurement measures they morally deplore? We suggest that to understand this change of treatment norms, we must move close to everyday work practices and appreciate the importance of material–technical treatment options as well as the interplay of professional ethics and identity. The cardiac treatment of brain-dead donors may thereby illuminate how treatment norms develop on the ground and thus can theoretically develop our understanding of the mechanisms associated with increasingly ‘aggressive organ harvesting’.

An alternative analytical method based on ultrasound micro bath hydrolysis and GC-MS analysis for the characterization of organic biomarkers in archaeological ceramics.

The analysis of organic biomarkers in ancient and valuable archaeological remains provides a worthwhile source of information regarding their management. This work was focused on the development of an analytical procedure to characterize organic residues that have remained in archaeological ceramic samples. A novel analytical approach based on an alkaline hydrolysis by means of an ultrasound micro bath followed by liquid extraction was proposed to isolate saturated and unsaturated fatty acids, degradation products such as dihydroxy acids or dienoic fatty acids, isoprenoid fatty acids, and many other biomarkers from archaeological remains. This main goal has been achieved after the optimization of the main parameters affecting the hydrolysis step, the extraction procedure, and the derivatization step prior to the gas chromatography-mass spectrometry analysis. In this work, archaeological ceramic remains suspected to have been used by Basque Whalers to store whale oil in the period from the sixteenth to the seventeenth century were studied. Nevertheless, the proposed method is useful to determine the organic remains preserved in many other archaeological ceramic remains. Moreover, this methodology can be used to determine organic remains in any porous ceramic, archaeological or not. The preliminary results of the analysis of ceramic vessels led to the determination of some interesting unsaturated compounds such as 11-eicosenoic acid, an important biomarker of marine commodities, and several saturated fatty acids, which could be indicative of having used the vessels to store whale oil.

Primary and secondary organics in the tropical Amazonian rainforest aerosols: chiral analysis of 2-methyltetraols.

This work presents the application of a new method to facilitate the distinction between biologically produced (primary) and atmospherically produced (secondary) organic compounds in ambient aerosols based on their chirality. The compounds chosen for this analysis were the stereomers of 2-methyltetraols, (2R,3S)- and (2S,3R)-methylerythritol, (l- and d-form, respectively), and (2S,3S)- and (2R,3R)-methylthreitol (l- and d-form), shown previously to display some enantiomeric excesses in atmospheric aerosols, thus to have at least a partial biological origin. In this work PM10 aerosol fractions were collected in a remote tropical rainforest environment near Manaus, Brazil, between June 2008 and June 2009 and analysed. Both 2-methylerythritol and 2-methylthreitol displayed a net excess of one enantiomer (either the l- or the d-form) in 60 to 72% of these samples. These net enantiomeric excesses corresponded to compounds entirely biological but accounted for only about 5% of the total 2-methyltetrol mass in all the samples. Further analysis showed that, in addition, a large mass of the racemic fractions (equal mixtures of d- and l-forms) was also biological. Estimating the contribution of secondary reactions from the isomeric ratios measured in the samples (=ratios 2-methylthreitol over 2-methylerythritol), the mass fraction of secondary methyltetrols in these samples was estimated to a maximum of 31% and their primary fraction to a minimum of 69%. Such large primary fractions could have been expected in PM10 aerosols, largely influenced by biological emissions, and would now need to be investigated in finer aerosols. This work demonstrates the effectiveness of chiral and isomeric analyses as the first direct tool to assess the primary and secondary fractions of organic aerosols.

The evaluative approach of occupational therapy, centred on the person, on an analysis of performance and an assessment of the work environment, can provide important information for planning interventions to increase safety at work. The reliability of work performance is influenced by many factors, some of which are not directly dependent on humans, such as those related to the environment, to materials, to spaces, to places and to the organization of work; others, however, are closely related to human behaviours. For this reason, for the purpose of ensuring prevention of all harmful events, the process of risk evaluation must also include an analysis of the role of human behaviour and functional capacity. In our daily clinical practice, we Occupational Therapists use work to promote the wellbeing and health of people by involving them in activities, with the knowledge that every occupation is perceived by an individual as something particularly personal and significant.

Non-governmental organizations, democracy, and HIV prevalence: a cross-national analysis.

Despite the scale, reach, and global impact of the human immunodeficiency virus (HIV), its study has remained largely at the purview of various micro-level analyses (e.g., Gutmann 2007; Levi and Vitória 2002). However, differences in prevalence rates at the national level suggest that other forces might be at work. Following the work of McIntosh and Thomas (2004), the only cross-national study of HIV/AIDS published to our knowledge, we conduct a cross-national analysis that examines world polity ideas that higher levels of health and women’s non-governmental organizations (NGOs) should be associated with lower levels of HIV prevalence. Initially, we find no support for these hypotheses. However, we respecify our models to test a political opportunity structure hypothesis that democracy enhances the ability of health and women’s NGOs to deal with HIV. We test this line of reasoning by including an interaction term between democracy and the health and women’s NGO variables. In doing so, we find that health and women’s NGOs are associated with lower levels of HIV prevalence in democratic rather than repressive nations.

A nanobiosensor for dynamic single cell analysis during microvascular self-organization.

The formation of microvascular networks plays essential roles in regenerative medicine and tissue engineering. Nevertheless, the self-organization mechanisms underlying the dynamic morphogenic process are poorly understood due to a paucity of effective tools for mapping the spatiotemporal dynamics of single cell behaviors. By establishing a single cell nanobiosensor along with live cell imaging, we perform dynamic single cell analysis of the morphology, displacement, and gene expression during microvascular self-organization. Dynamic single cell analysis reveals that endothelial cells self-organize into subpopulations with specialized phenotypes to form microvascular networks and identifies the involvement of Notch1-Dll4 signaling in regulating the cell subpopulations. The cell phenotype correlates with the initial Dll4 mRNA expression level and each subpopulation displays a unique dynamic Dll4 mRNA expression profile. Pharmacological perturbations and RNA interference of Notch1-Dll4 signaling modulate the cell subpopulations and modify the morphology of the microvascular network. Taken together, a nanobiosensor enables a dynamic single cell analysis approach underscoring the importance of Notch1-Dll4 signaling in microvascular self-organization.

How do medical residents organize their work in settings where queue demands are heavy and resources are limited? Under such conditions, a queue theory would predict the delivery of care that is indifferent to clients' needs or that gets rid of clients as quickly as possible. In an exploratory case study of medical residents in a Veterans Administration outpatient clinic, we found instead that the medical residents' work was characterized by a high level of professional commitment: they provided thorough medical examinations and attempted to expedite patient care in other ways. We attribute the residents' professional ethos to opportunities provided in the VA hospital to learn the craft of routine medicine and to be directly responsible for patient care; such opportunities were not available in other settings.

Logistic regression (backward stepwise model) was used to identify significant predictors of BMI and to analyze odds ratios. Mean BMI was 33.40 kg/m, with 64.2% obese (BMI > 30 kg/m) and 18.4% extreme/morbidly obese (BMI > 40 kg/m). Working more than 11 daily hours was associated with statistically significant increased odds for being extreme obese. Findings suggest that longer work hours (>11 hours daily) have a major influence on odds for obesity among this population. The results align with recent NIOSH calls for integrated approaches to worker health.

The shortage of nurses is a problem in many countries. In Japan, the distribution of nurses across different care settings is uneven: the shortage of nurses in home healthcare and nursing homes is more serious than in hospitals. Earlier research has identified numerous factors affecting nurses' intention to leave work (e.g., job control, family-related variables, work-family conflict); however, these factors' levels and effect size may vary between nurses in hospitals, home healthcare, and nursing homes. This study measured job control, family-related variables, and work-family conflict among nurses in hospitals, home healthcare, and nursing homes, and compared these variables' levels and effect size on nurses' intention to leave their organization or profession between these care settings. The research design was cross-sectional. Participating nurses from hospitals, home healthcare facilities, and nursing homes self-administered an anonymous questionnaire survey; nurses were recruited from the Kyushu district of Japan. Nurses from nine hospitals, 86 home healthcare offices, and 107 nursing homes participated. We measured nurses' intention to leave nursing or their organization, perceived job control, family variables and work-family conflict. We analyzed 1461 participants (response rate: 81.7%). The level of job control, family variables, and work-family conflict affecting nurses varied between hospitals, home healthcare, and nursing homes; additionally, these variables' effect on nurses' intention to leave their organization or profession varied between these care settings. Work-family conflict, family variables, and job control most strongly predicted nurses' intention to leave their organization or profession in hospitals, home healthcare, and nursing homes, respectively. Interventions aiming to increase nurse retention should distinguish between care settings. Regarding hospitals, reducing nurses' work-family conflict will increase nurse retention. Regarding

Swine wastewater is one of the most serious pollution sources, and it has attracted a great public concern in China. Anaerobic digestion technology is extensively used in swine wastewater treatment. However, the anaerobic digestion effluents are difficult to meet the discharge standard. The results from batch experiments showed that plenty of refractory organic matter remained in the effluents after mesophilic anaerobic digestion for 30 days. The effluent total COD (tCOD) and soluble COD (sCOD) were 483 and 324 mg/L, respectively, with the sCOD/tCOD ratio of 0.671. Fluorescence excitation-emission matrix (EEM) coupled with parallel factor analysis (PARAFAC) revealed that the dissolved organic matter in the effluents was tryptophan-like substance, humic acid substance, and fulvic acid substance. Based on the appearance time during anaerobic digestion, tryptophan-like substance and humic acid substance were inferred to originate from the raw swine wastewater, and the fulvic acid substance was inferred to be formed in the anaerobic digestion. This work has revealed the source of residual organic matter in anaerobic digestion of swine wastewater and has provided some valuable information for the post-treatment.

An Ideal Observer Analysis of Visual Working Memory

PubMed Central

Sims, Chris R.; Jacobs, Robert A.; Knill, David C.

2013-01-01

Limits in visual working memory (VWM) strongly constrain human performance across many tasks. However, the nature of these limits is not well understood. In this paper we develop an ideal observer analysis of human visual working memory, by deriving the expected behavior of an optimally performing, but limited-capacity memory system. This analysis is framed around rate–distortion theory, a branch of information theory that provides optimal bounds on the accuracy of information transmission subject to a fixed information capacity. The result of the ideal observer analysis is a theoretical framework that provides a task-independent and quantitative definition of visual memory capacity and yields novel predictions regarding human performance. These predictions are subsequently evaluated and confirmed in two empirical studies. Further, the framework is general enough to allow the specification and testing of alternative models of visual memory (for example, how capacity is distributed across multiple items). We demonstrate that a simple model developed on the basis of the ideal observer analysis—one which allows variability in the number of stored memory representations, but does not assume the presence of a fixed item limit—provides an excellent account of the empirical data, and further offers a principled re-interpretation of existing models of visual working memory.

Preliminary analysis of compound systems based on high temperature fuel cell, gas turbine and Organic Rankine Cycle

NASA Astrophysics Data System (ADS)

Sánchez, D.; Muñoz de Escalona, J. M.; Monje, B.; Chacartegui, R.; Sánchez, T.

This article presents a novel proposal for complex hybrid systems comprising high temperature fuel cells and thermal engines. In this case, the system is composed by a molten carbonate fuel cell with cascaded hot air turbine and Organic Rankine Cycle (ORC), a layout that is based on subsequent waste heat recovery for additional power production. The work will credit that it is possible to achieve 60% efficiency even if the fuel cell operates at atmospheric pressure. The first part of the analysis focuses on selecting the working fluid of the Organic Rankine Cycle. After a thermodynamic optimisation, toluene turns out to be the most efficient fluid in terms of cycle performance. However, it is also detected that the performance of the heat recovery vapour generator is equally important, what makes R245fa be the most interesting fluid due to its balanced thermal and HRVG efficiencies that yield the highest global bottoming cycle efficiency. When this fluid is employed in the compound system, conservative operating conditions permit achieving 60% global system efficiency, therefore accomplishing the initial objective set up in the work. A simultaneous optimisation of gas turbine (pressure ratio) and ORC (live vapour pressure) is then presented, to check if the previous results are improved or if the fluid of choice must be replaced. Eventually, even if system performance improves for some fluids, it is concluded that (i) R245fa is the most efficient fluid and (ii) the operating conditions considered in the previous analysis are still valid. The work concludes with an assessment about safety-related aspects of using hydrocarbons in the system. Flammability is studied, showing that R245fa is the most interesting fluid also in this regard due to its inert behaviour, as opposed to the other fluids under consideration all of which are highly flammable.

The aim of this meta-analysis of studies of workers in the health and social care sector was to examine the relationship between interprofessional work and employee outcomes of job stress, autonomy, burnout, engagement, job satisfaction, turnover intention, and perceived service quality, and to examine the influence of different moderators on those relationships. A systematic literature search of the PsycInfo, Embase, Medline, and the Cumulative Index to Nursing and Allied Health Literature databases was conducted to identify relevant articles. A total of 45 articles with results for 53 independent samples was included in the meta-analysis. A random effects model was used to estimate the mean effect sizes (correlations). Most employees were nurses working in hospitals. Interprofessional work was weakly negatively associated with job stress, burnout, and turnover intention (range mean r = -.13 to -.22); and was moderately positively associated with autonomy, engagement, job satisfaction, and perceived service quality (range mean r =.33 to .46). When feasible, interprofessional work was categorized as teamwork (most intensive), collaboration, or cooperation. Teamwork, the most intense of three forms of interprofessional work, promoted lower burnout and turnover intention. The results of this meta-analysis suggest that interprofessional work is linked to better well-being for employees in health and social care. © 2018 Wiley Periodicals, Inc.

Cognitive work analysis has been applied in the design of numerous sociotechnical systems. The process used to translate analysis outputs into design concepts, however, is not always clear. Moreover, structured processes for translating the outputs of ergonomics methods into concrete designs are lacking. This paper introduces the Cognitive Work Analysis Design Toolkit (CWA-DT), a design approach which has been developed specifically to provide a structured means of incorporating cognitive work analysis outputs in design using design principles and values derived from sociotechnical systems theory. This paper outlines the CWA-DT and describes its application in a public transport ticketing design case study. Qualitative and quantitative evaluations of the process provide promising early evidence that the toolkit fulfils the evaluation criteria identified for its success, with opportunities for improvement also highlighted. The Cognitive Work Analysis Design Toolkit has been developed to provide ergonomics practitioners with a structured approach for translating the outputs of cognitive work analysis into design solutions. This paper demonstrates an application of the toolkit and provides evaluation findings.

Mars Organic Detector III: a versatile instrument for detection of bio-organic signatures on Mars

Recent advances in the development of microfabricated lab-on-a-chip analysis systems have enhanced the feasibility and capabilities of in situ chemical and biochemical analyzers. While a wide variety of bio-organic molecules can be probed, we have focused our initial studies on the development of an amino acid analyzer with the hypothesis that extraterrestrial life would be based on homochiral amino acid polymers. In previous work, we developed a prototype electrophoresis chip, detection system and analysis method where the hydrolyzed amino acids were labeled with fluorescein and then analyzed in minutes via a capillary zone electrophoresis (CZE) separation in the presence of cyclodextrin as the chiral recognition agent. In more recent work, we have demonstrated the feasibility of performing amino acid composition and chirality analyses using fluorescamine as the labeling reagent. Fluorescamine is advantageous because it reacts more rapidly with amino acids, has a low fluorescence background and because such a chemistry would interface directly with the Mars Organic Detector (MOD-I) concept being developed at Scripps. A more advanced analysis system called MOD-III is introduced here with the ability to analyze zwitterionic amino acids, nucleobases, sugars, and organic acids and bases using novel capture matrix chemistries. MOD-III, which is enabled by the nanoliter valves, pumps and reactors presented here, will provide a wide spectrum of organic chemical analyses and is suitable for a variety of in situ missions.

Development and Testing of the Healthy Work Environment Inventory: A Reliable Tool for Assessing Work Environment Health and Satisfaction.

Fostering healthy work environments that enhance job satisfaction and reflect high levels of employee engagement and productivity is imperative for all organizations. This is especially true for health care organizations where unhealthy work conditions can lead to poor patient outcomes. A convenience sample of 520 nursing faculty and practice-based nurses in the United States participated in a study to test the psychometric properties of the Healthy Work Environment Inventory (HWEI). A factor analysis and other reliability analyses support the use of the HWEI as a valid and reliable instrument to measure perceptions of work environment health. The HWEI is a 20-item psychometrically sound instrument to measure perceptions of the health of the work environment. It may be completed either as an individual exercise or by all members of a team to compare perceptions of work environment health, to determine areas of strength and improvement, and to form the basis for interviewing.

Managing mechanistic and organic structure in health care organizations.

PubMed

Olden, Peter C

2012-01-01

Managers at all levels in a health care organization must organize work to achieve the organization's mission and goals. This requires managers to decide the organization structure, which involves dividing the work among jobs and departments and then coordinating them all toward the common purpose. Organization structure, which is reflected in an organization chart, may range on a continuum from very mechanistic to very organic. Managers must decide how mechanistic versus how organic to make the entire organization and each of its departments. To do this, managers should carefully consider 5 factors for the organization and for each individual department: external environment, goals, work production, size, and culture. Some factors may push toward more mechanistic structure, whereas others may push in the opposite direction toward more organic structure. Practical advice can help managers at all levels design appropriate structure for their departments and organization.

It's the nature of the work: examining behavior-based sources of work-family conflict across occupations.

PubMed

Dierdorff, Erich C; Ellington, J Kemp

2008-07-01

The consequences of work-family conflict for both individuals and organizations have been well documented, and the various sources of such conflict have received substantial attention. However, the vast majority of extant research has focused on only time- and strain-based sources, largely neglecting behavior-based sources. Integrating two nationally representative databases, the authors examine 3 behavior-based antecedents of work-family conflict linked specifically to occupational work role requirements (interdependence, responsibility for others, and interpersonal conflict). Results from multilevel analysis indicate that significant variance in work-family conflict is attributable to the occupation in which someone works. Interdependence and responsibility for others predict work-family conflict, even after controlling for several time- and strain-based sources.

Comparative modular analysis of gene expression in vertebrate organs.

Piasecka, Barbara; Kutalik, Zoltán; Roux, Julien; Bergmann, Sven; Robinson-Rechavi, Marc

2012-03-29

The degree of conservation of gene expression between homologous organs largely remains an open question. Several recent studies reported some evidence in favor of such conservation. Most studies compute organs' similarity across all orthologous genes, whereas the expression level of many genes are not informative about organ specificity. Here, we use a modularization algorithm to overcome this limitation through the identification of inter-species co-modules of organs and genes. We identify such co-modules using mouse and human microarray expression data. They are functionally coherent both in terms of genes and of organs from both organisms. We show that a large proportion of genes belonging to the same co-module are orthologous between mouse and human. Moreover, their zebrafish orthologs also tend to be expressed in the corresponding homologous organs. Notable exceptions to the general pattern of conservation are the testis and the olfactory bulb. Interestingly, some co-modules consist of single organs, while others combine several functionally related organs. For instance, amygdala, cerebral cortex, hypothalamus and spinal cord form a clearly discernible unit of expression, both in mouse and human. Our study provides a new framework for comparative analysis which will be applicable also to other sets of large-scale phenotypic data collected across different species.

This study aims to verify the effect of physically removing the outer surface of contaminated concrete on total contents and on potential mobility of pollutants by means of leaching tests. Reclaimed concrete from 3 industrial sites in Sweden were included: A tar impregnated military storage, a military tar track-depot, as well as concrete constructions used for disposing of pesticide production surplus and residues. Solid materials and leachates from batch and column leaching tests were analysed for metals, Cl, F, SO4, DOC and contents of suspected organic compounds (polycyclic aromatic hydrocarbons, PAH, and pesticides/substances for pesticide production such as phenoxy acids, chlorophenols and chlorocresols, respectively). In case of PAH contaminated concrete, results indicate that removing 1 or 5 mm of the surface lead to total concentrations below the Swedish guidelines for recycling of aggregates and soil in groundwork constructions. 3 out of 4 concrete samples contaminated with pesticides fulfilled Swedish guidelines for contaminated soil. Results from batch and column leaching tests indicated, however, that concentrations above environmental quality standards for certain PAH and phenoxy acids, respectively, might occur at site when the crushed concrete is recycled in groundwork constructions. As leaching tests engaged in the study deviated from leaching test standards with a limited number of samples, the potential impact of the leaching tests' equipment on measured PAH and pesticide leachate concentrations has to be evaluated in future work.

Enantiomeric and Isotopic Analysis of Organic Compounds in Carbonaceous Meteorites

NASA Technical Reports Server (NTRS)

Cooper, George

2004-01-01

Carbonaceous meteorites are relatively enriched in soluble organic compounds. The Murchison and Murray meteorites contain numerous compounds of interest in the study of early solar system organic chemistry and organic compounds of potential importance for the origin of life. These include: amino acids, amides, carboxylic acids, and polyols. This talk will focus on the enantiomeric and isotopic analysis of individual meteoritic compounds - primarily polyol acids. The analyses will determine if, in addition to certain amino acids from Murchison, another potentially important class of prebiotic compounds also contains enantiomeric excesses, i.e., excesses that could have contributed to the current homochirality of life. Preliminary enantiomeric and isotopic (C- 13) measurements of Murchison glyceric acid show that it is indeed extraterrestrial. C-13 and D isotope analysis of meteoritic sugar alcohols (glycerol, threitol, ribitol, etc.) has shown that they are also indigenous to the meteorite.

The main objective of this work was to study the effect of the kerogen isolation procedures on maturity parameters of organic matter using optical microscopes. This work represents the results of the Organic Matter Concentration Working Group (OMCWG) of the International Committee for Coal and Organic Petrology (ICCP) during the years 2008 and 2009. Four samples have been analysed covering a range of maturity (low and moderate) and terrestrial and marine geological settings. The analyses comprise random vitrinite reflectance measured on both kerogen concentrate and whole rock mounts and fluorescence spectra taken on alginite. Eighteen participants from twelve laboratories from all over the world performed the analyses. Samples of continental settings contained enough vitrinite for participants to record around 50 measurements whereas fewer readings were taken on samples from marine setting. The scatter of results was also larger in the samples of marine origin. Similar vitrinite reflectance values were in general recorded in the whole rock and in the kerogen concentrate. The small deviations of the trend cannot be attributed to the acid treatment involved in kerogen isolation but to reasons related to components identification or to the difficulty to achieve a good polish of samples with high mineral matter content. In samples difficult to polish, vitrinite reflectance was measured on whole rock tended to be lower. The presence or absence of rock fabric affected the selection of the vitrinite population for measurement and this also had an influence in the average value reported and in the scatter of the results. Slightly lower standard deviations were reported for the analyses run on kerogen concentrates. Considering the spectral fluorescence results, it was observed that the ??max presents a shift to higher wavelengths in the kerogen concentrate sample in comparison to the whole-rock sample, thus revealing an influence of preparation methods (acid treatment) on

Functional analysis of tight junction organization.

PubMed

DiBona, D R

1985-01-01

The functional basis of tight junction design has been examined from the point of view that this rate-limiting barrier to paracellular transport is a multicompartment system. Review of the osmotic sensitivity of these structures points to the need for this sort of analysis for meaningful correlation of structure and function under a range of conditions. A similar conclusion is drawn with respect to results from voltage-clamping protocols where reversal of spontaneous transmural potential difference elicits parallel changes in both structure and function in much the same way as does reversal of naturally occurring osmotic gradients. In each case, it becomes necessary to regard the junction as a functionally polarized structure to account for observations of its rectifying properties. Lastly, the details of experimentally-induced junction deformation are examined in light of current theories of its organization; arguments are presented in favor of the view that the primary components of intramembranous organization (as viewed with freeze-fracture techniques) are lipidic rather than proteinaceous.

Apparatus and processes are described for recognizing and identifying materials. Characteristic spectra are obtained for the materials via spectroscopy techniques including nuclear magnetic resonance spectroscopy, infrared absorption analysis, x-ray analysis, mass spectroscopy and gas chromatography. Desired portions of the spectra may be selected and then placed in proper form and format for presentation to a number of input layer neurons in an offline neural network. The network is first trained according to a predetermined training process; it may then be employed to identify particular materials. Such apparatus and processes are particularly useful for recognizing and identifying organic compounds such as complex carbohydrates, whose spectra conventionally require a high level of training and many hours of hard work to identify, and are frequently indistinguishable from one another by human interpretation.

Recent trends in water analysis triggering future monitoring of organic micropollutants.

Schmidt, Torsten C

2018-03-21

Water analysis has been an important area since the beginning of analytical chemistry. The focus though has shifted substantially: from minerals and the main constituents of water in the time of Carl Remigius Fresenius to a multitude of, in particular, organic compounds at concentrations down to the sub-nanogram per liter level nowadays. This was possible only because of numerous innovations in instrumentation in recent decades, drivers of which are briefly discussed. In addition to the high demands on sensitivity, high throughput by automation and short analysis times are major requirements. In this article, some recent developments in the chemical analysis of organic micropollutants (OMPs) are presented. These include the analysis of priority pollutants in whole water samples, extension of the analytical window, in particular to encompass highly polar compounds, the trend toward more than one separation dimension before mass spectrometric detection, and ways of coping with unknown analytes by suspect and nontarget screening approaches involving high-resolution mass spectrometry. Furthermore, beyond gathering reliable concentration data for many OMPs, the question of the relevance of such data for the aquatic system under scrutiny is becoming ever more important. To that end, effect-based analytics can be used and may become part of future routine monitoring, mostly with a focus on adverse effects of OMPs in specific test systems mimicking environmental impacts. Despite advances in the field of water analysis in recent years, there are still many challenges for further analytical research.

The Thermal Evolved-Gas Analyzer (TEGA) instrument onboard the 2007 Phoenix Lander will perform differential scanning calorimetry (DSC) and evolved-gas analysis of soil samples collected from the surface. Data from the instrument will be compared with Mars analog mineral standards, collected under TEGA Mars-like conditions to identify the volatile-bearing mineral phases [1] (e.g., Fe-oxyhydroxides, phyllosilicates, carbonates, and sulfates) found in the Martian soil. Concurrently, the instrument will be looking for indications of organics that might also be present in the soil. Organic molecules are necessary building blocks for life, although their presence in the ice or soil does not indicate life itself. The spacecraft will certainly bring organic contaminants to Mars even though numerous steps were taken to minimize contamination during the spacecraft assembly and testing. It will be essential to distinguish possible Mars organics from terrestrial contamination when TEGA instrument begins analyzing icy soils. To address the above, an Organic Free Blank (OFB) was designed, built, tested, and mounted on the Phoenix spacecraft providing a baseline for distinguishing Mars organics from terrestrial organic contamination. Our objective in this report is to describe some of the considerations used in selecting the OFB material and then report on the processing and analysis of the final candidate material

Epidemiology studies suggested that shift work or night work may be linked to prostate cancer (PCa); the relationship, however, remains controversy. PubMed, ScienceDirect, and Embase (Ovid) databases were searched before (started from the building of the databases) February 4, 2017 for eligible cohort studies. We pooled the evidence included by a random- or fixed-effect model, according to the heterogeneity. A predefined subgroup analysis was conducted to see the potential discrepancy between groups. Sensitivity analysis was used to test whether our results were stale. Nine cohort studies were eligible for meta-analysis with 2,570,790 male subjects. Our meta-analysis showed that, under the fixed-effect model, the pooled relevant risk (RR) of PCa was 1.05 (95% confidence interval [CI]: 1.00, 1.11; P = .06; I = 24.00%) for men who had ever engaged in night shift work; and under the random-effect model, the pooled RR was 1.08 (0.99, 1.17; P = .08; I = 24.00%). Subgroup analysis showed the RR of PCa among males in western countries was 1.05 (95% CI: 0.99, 1.11; P = .09; I = 0.00%), while among Asian countries it was 2.45 (95% CI: 1.19, 5.04; P = .02; I = 0.00%); and the RR was 1.04 (95% CI: 0.95, 1.14; P = .40; I = 29.20%) for the high-quality group compared with 1.21 (95% CI: 1.03, 1.41; P = .02; I = 0.00%) for the moderate/low-quality group. Sensitivity analysis showed robust results. Based on the current evidence of cohort studies, we found no obvious association between night shift work and PCa. However, our subgroup analysis suggests that night shift work may increase the risk of PCa in Asian men. Some evidence of a small study effect was observed in this meta-analysis.

To assess the predictive ability of various aspects of the work environment for organizational commitment. A questionnaire measuring three dimensions of organizational commitment along with five aspects of work environment and 10 demographic and work setting characteristics was sent to a national, convenience sample of clinical laboratory professionals. All persons obtaining the CLS certification by NCA from January 1, 1997 to December 31, 2006. Only respondents who worked full-time in a clinical laboratory setting were included in the database. Levels of affective, normative, and continuance organizational commitment, organizational support, role clarity, role conflict, transformational leadership behavior of supervisor, and organizational type, total years work experience in clinical laboratories, and educational level of respondents. Questionnaire items used either a 7-point or 5-point Likert response scale. Based on multiple regression analysis for the 427 respondents, organizational support and transformational leadership behavior were found to be significant positive predictors of affective and normative organizational commitment. Work setting (non-hospital laboratory) and total years of work experience in clinical laboratories were found to be significant positive predictors of continuance organizational commitment. Overall the organizational commitment levels for all three dimensions were at the neutral rating or below in the slightly disagree range. The results indicate a less than optimal level of organizational commitment to employers, which were predominantly hospitals, by CLS practitioners. This may result in continuing retention problems for hospital laboratories. The results offer strategies for improving organizational commitment via the significant predictors.

Performance Analysis: Work Control Events Identified January - August 2010

2011-01-14

This performance analysis evaluated 24 events that occurred at LLNL from January through August 2010. The analysis identified areas of potential work control process and/or implementation weaknesses and several common underlying causes. Human performance improvement and safety culture factors were part of the causal analysis of each event and were analyzed. The collective significance of all events in 2010, as measured by the occurrence reporting significance category and by the proportion of events that have been reported to the DOE ORPS under the ''management concerns'' reporting criteria, does not appear to have increased in 2010. The frequency of reporting inmore » each of the significance categories has not changed in 2010 compared to the previous four years. There is no change indicating a trend in the significance category and there has been no increase in the proportion of occurrences reported in the higher significance category. Also, the frequency of events, 42 events reported through August 2010, is not greater than in previous years and is below the average of 63 occurrences per year at LLNL since 2006. Over the previous four years, an average of 43% of the LLNL's reported occurrences have been reported as either ''management concerns'' or ''near misses.'' In 2010, 29% of the occurrences have been reported as ''management concerns'' or ''near misses.'' This rate indicates that LLNL is now reporting fewer ''management concern'' and ''near miss'' occurrences compared to the previous four years. From 2008 to the present, LLNL senior management has undertaken a series of initiatives to strengthen the work planning and control system with the primary objective to improve worker safety. In 2008, the LLNL Deputy Director established the Work Control Integrated Project Team to develop the core requirements and graded elements of an institutional work planning and control system. By the end of that year this system was documented and implementation had begun

Therefore, investigations of air quality are increasing and supported by many institutions in recent years. Air pollution in Istanbul contains many components that originate from a wide range of industrial, heating, motor vehicle, and natural emissions sources. VOC, originating mainly from automobile exhaust, secondhand smoke and building materials, are one of these compounds containing some thousands of chemicals. In spite of the risks to human health, relatively little is known about the levels of VOC in Istanbul. In this study, ambient air quality measurements of 32 VOCs including hydrocarbons, halogenated hydrocarbons and carbonyls were conducted in Kağıthane (Golden Horn) region in Istanbul during the winter season of 2011 in order to develop the necessary scientific framework for the subsequent developments. Kağıthane creek valley is the source part of the Golden Horn and one of the most polluted locations in Istanbul due to its topographical form and pollutant sources in the region. In this valley, horizontal and vertical atmospheric motions are very weak. The target compounds most commonly found were benzene, toluene, xylene and ethyl benzene. Concentrations of total hydrocarbons ranged between 1.0 and 10.0 parts per billion, by volume (ppbv). Ambient air levels of halogenated hydrocarbons appeared to exhibit unique spatial variations and no single factor seemed to explain trends for this group of

Organ donation agency: A discourse analysis of correspondence between donor and organ recipient families.

PubMed

Galasiński, Dariusz; Sque, Magi

2016-11-01

Studies about the psychosocial issues concerning organ donation and transplantation tend to focus on the experiences of donor or recipient families. Little is known about the part played by correspondence exchanged between these two groups; in particular how they perceive the agency of organ donation. This is the first analysis to address the representation of the act of donation from the viewpoint of both donor and recipient families through interrogation of archived correspondence data, using linguistic techniques. The data was drawn from a collection of letters, from four USA organ procurement organisations, exchanged between donor and transplant recipient families. Donor families consistently linguistically ascribed agency and accountability for donation to the person who died, the donor. For the recipient families, on the other hand, the 'giver' was mainly implied, ambiguous or ascribed to the donor family. © 2016 Foundation for the Sociology of Health & Illness.

To understand the organization of and the working conditions in family health care support centers, as well as subjective experiences related to work in two of these centers. This was a case study carried out during 2011 and 2012 in two family health care support centers in Sao Paulo, Southeastern Brazil. Data were collected and analyzed using two theoretical-methodological references from ergonomics and work psychodynamics influenced, respectively, by ergonomic work analysis, developed based on open observations of a variety of tasks and on interviews and in practice in work psychodynamics, carried out using think tanks about the work. The work of the Family Health Care Support Centers in question is constituted on the bases of complex, diversified actions to be shared among the various professionals and teams involved. Innovative technological tools, which are not often adopted by primary health care professionals, are used and the parameters and productivity measures do not encompass the specificity and the complexity of the work performed. These situations require constant organizational rearrangement, especially between the Family Health Care Support Centers and the Family Health Care Teams, causing difficulties in carrying out the work as well as in constituting the identity of the professionals studied. The study attempts to lend greater visibility to the work processes at the Family Health Care Support Centers in order to contribute to advances in public policy on primary healthcare. It is important to stress that introducing changes at work, which affect both its organization and work conditions, is above all a commitment, which to be effective, must be permanent and must involve the different levels of hierarchy.

The goal of this study was to identify the tendency toward donations of tissue and organs from donors with brain death between 2001 and 2016 as registered by an organ procurement organization in São Paulo City. This quantitative, retrospective, exploratory study encompassed all Tissue and Organ Donation Terms signed between 2001 and 2016. A logistic regression model was applied to verify whether there was an upward or downward trend in donation. After statistical analysis, a significant change trend was identified in skin, bones, valve, vessel, heart, lung, and pancreas donations, indicating an increase in the donation rate through the years. The donation rate did not show changes over the years for donations of liver, kidneys, and corneas. The decision-making process regarding organ and tissue donation is restricted not only to the dilemma of whether to donate but another question then arises as well: which organs and tissues are to be donated? The discrepancy between the authorization for organ donation and the authorization for tissue donation, as well as the option for one or another organ and/or tissue, must be thoroughly examined because these factors directly affect the number of transplants and acquirements effectively accomplished. These factors may be related to explaining to one's relatives aspects of the surgery, body reassembling, and usage of such organs and/or tissues. They may also be related to the lack of knowledge concerning organ donation and the symbolism represented by the organ and/or tissue, among other factors. Copyright © 2018 Elsevier Inc.

To lay groundwork for identifying patterns of injury etiology, we sought to describe injury experience associated with types of work performed at construction sites by examining workers' compensation (WC) claims for the 32,081 construction workers who built Denver International Airport (DIA). Injury rates and WC payment rates were calculated for 25 types of work based on claims and payroll data reported to DIA's owner-controlled insurance program according to National Council on Compensation Insurance job classifications. By linking DIA claims with corresponding lost-work-time (LWT) claims filed with Colorado's Workers' Compensation Division, we were also able to obtain and examine both total and median lost days for each type of work. Injury experience varied widely among the types of construction work. Workers building elevators and conduits and installing glass, metal, or steel were at particularly high risk of both LWT and non-LWT injury. Median days lost by injured workers was highest (202 days) for driving/trucking. Median days lost for most types of work was much greater than previously reported for construction: 40 days or more for 18 of the 25 types of work analyzed. WC payment rates reflect both number and severity of injuries and were generally not significantly different from expected losses. They were, however, significantly higher than expected for driving/trucking, metal/steel installation, inspection/analysis, and elevator construction. Analysis of injury data by type of work allows targeting of safety resources to high risk construction work and would be useful in prospective surveillance at large construction sites with centrally administered workers' compensation plans.

This systematic review and meta-analysis evaluated the associations between shift work patterns and risks of specific types of obesity. PubMed was searched until March 2017 for observational studies that examined the relationships between shift work patterns and obesity. Odds ratio for obesity was extracted using a fixed-effects or random-effects model. Subgroup meta-analyses were carried out for study design, specific obesity types and characteristics of shift work pattern. A total of 28 studies were included in this meta-analysis. The overall odds ratio of night shift work was 1.23 (95% confidence interval = 1.17-1.29) for risk of obesity/overweight. Cross-sectional studies showed a higher risk of 1.26 than those with the cohort design (risk ratio = 1.10). Shift workers had a higher frequency of developing abdominal obesity (odds ratio = 1.35) than other obesity types. Permanent night workers demonstrated a 29% higher risk than rotating shift workers (odds ratio 1.43 vs. 1.14). This meta-analysis confirmed the risks of night shift work for the development of overweight and obesity with a potential gradient association suggested, especially for abdominal obesity. Modification of working schedules is recommended, particularly for prolonged permanent night work. More accurate and detailed measurements on shift work patterns should be conducted in future research. © 2017 World Obesity Federation.

Cooperation of return-to-work professionals: the challenges of multi-actor work disability management.

Liukko, Jyri; Kuuva, Niina

2017-07-01

This article explores which concrete factors hinder or facilitate the cooperation of return-to-work (RTW) professionals in a complex system of multiple stakeholders. The empirical material consists of in-depth interviews with 24 RTW professionals from various organizations involved in work disability management in Finland. The interviews were analyzed using thematic content analysis. The study revealed several kinds of challenges in the cooperation of the professionals. These were related to two partly interrelated themes: communication and distribution of responsibility. The most difficult problems were connected to the cooperation between public employment offices and other stakeholders. However, the study distinguished notable regional differences depending primarily on the scale of the local network. The main areas of improvement proposed by the interviewees were related to better networking of case managers and expansion of expertise. The article argues for the importance of systematic networking and stresses the role of public employment services in the multi-actor management of work disabilities. The article contributes to existing work disability case management models by suggesting the employment administration system as an important component in addition to health care, workplace and insurance systems. The study also highlights the need for expansion of expertise in the field. Implications for Rehabilitation Cooperation between RTW professionals in public employment offices and other organizations involved in work disability management was considered inadequate. In order to improve the cooperation of RTW professionals, the stakeholders need to create more systematic ways of communication and networking with professionals in other organizations. There is a need to expand the expertise in work disability management and rehabilitation, partly by increasing the role of other professionals than physicians.

Countries importing organic coffee are facing the difficulty of assessing the quality of the product to distinguish original organic coffee from other coffees, thereby eliminating possible fraud. Many analytical methods are matrix sensitive and require matrix-matching reference materials for validation, which are currently nonexistent. This work aims to establish the trace element characterization of organic and conventional Brazilian coffees and to establish correlations with the related soil and the type of fertilizer and agrochemicals applied. It was observed that the variability in element concentrations between the various types of coffee is not so large, which emphasizes the need for analyticalmore » methods of high accuracy, reproducibility, and a well-known uncertainty.

Atmospheric Convective Organization: Self-Organized Criticality or Homeostasis?

NASA Astrophysics Data System (ADS)

Yano, Jun-Ichi

2015-04-01

Atmospheric convection has a tendency organized on a hierarchy of scales ranging from the mesoscale to the planetary scales, with the latter especially manifested by the Madden-Julian oscillation. The present talk examines two major possible mechanisms of self-organization identified in wider literature from a phenomenological thermodynamic point of view by analysing a planetary-scale cloud-resolving model simulation. The first mechanism is self-organized criticality. A saturation tendency of precipitation rate with the increasing column-integrated water, reminiscence of critical phenomena, indicates self-organized criticality. The second is a self-regulation mechanism that is known as homeostasis in biology. A thermodynamic argument suggests that such self-regulation maintains the column-integrated water below a threshold by increasing the precipitation rate. Previous analyses of both observational data as well as cloud-resolving model (CRM) experiments give mixed results. A satellite data analysis suggests self-organized criticality. Some observational data as well as CRM experiments support homeostasis. Other analyses point to a combination of these two interpretations. In this study, a CRM experiment over a planetary-scale domain with a constant sea-surface temperature is analyzed. This analysis shows that the relation between the column-integrated total water and precipitation suggests self-organized criticality, whereas the one between the column-integrated water vapor and precipitation suggests homeostasis. The concurrent presence of these two mechanisms are further elaborated by detailed statistical and budget analyses. These statistics are scale invariant, reflecting a spatial scaling of precipitation processes. These self-organization mechanisms are most likely be best theoretically understood by the energy cycle of the convective systems consisting of the kinetic energy and the cloud-work function. The author has already investigated the behavior of this

Analysis of major risk factors affecting those working in the agrarian sector (based on a sociological survey).

Issues related to labour potential, its state and problems have consistently been a focus of attention for the International Labour Organisation (ILO). Its respective analysis shows that labour potential problems remain unresolved in many countries of the world. According to the World Health Organisation (WHO), adverse working conditions are among major factors of occupational disease development in Europe and the reason for disabilities of economically active population during 2.5% of their lifetime. The aim of the present study is to identify and analyse major risk factors, which have a bearing on people working in agriculture in the course of exercising their occupation, with account of forms of ownership of agricultural enterprises. Carried out was a cross-sectional study involving a sociological survey of 412 respondents - those working in agriculture - who made up the primary group and the control group. The study revealed 21 risk factors, 9 of which were work-related. A modified elementary cybernetic model of studying impact efficiency was developed with the view of carrying out a structural analysis of the sample group and choosing relevant methodological approaches. It has been established that harmful factors related to working environment and one's lifestyle are decisive in the agrarian sector, particularly for workers of privately owned businesses. For one out of three respondents harmful working conditions manifested themselves as industrial noise (31.7±3.4), vibration (29.0±2.1) trunk bending and constrained working posture (36.6±3.4). The vast majority of agricultural workers (91.6±2.5) admitted they could not afford proper rest during their annual leave; male respondents abused alcohol (70.6±3.0) and smoking (41.4±2.0 per 100 workers). The research established the structure of risk factors, which is sequentially represented by the following groups: behavioral (smoking, drinking of alcohol, rest during annual leave, physical culture), working

The Mars Organic Analyzer (MOA), a portable microchip capillary electrophoresis (CE) instrument developed for sensitive amino acid analysis on Mars, is used to analyze laboratory standards and real-world samples for polycyclic aromatic hydrocarbons (PAHs). The microfabricated CE separation and analysis method for these hydrophobic analytes is optimized, resulting in a separation buffer consisting of 10 mM sulfobutylether-beta-cyclodextrin, 40 mM methyl-beta-cyclodextrin, 5 mM carbonate buffer at pH 10, 5 degrees C. A PAH standard consisting of seven PAHs found in extraterrestrial matter and two terrestrial PAHs is successfully baseline separated. Limits of detection for the components of the standard ranged from 2000 ppm to 6 ppb. Analysis of an environmental contamination standard from Lake Erie and of a hydrothermal vent chimney sample from the Guaymas Basin agreed with published composition. A Martian analogue sample from the Yungay Hills region of the Atacama Desert was analyzed and found to contain 9,10-diphenylanthracene, anthracene, anthanthrene, fluoranthene, perylene, and benzo[ghi]fluoranthene at ppm levels. This work establishes the viability of the MOA for detecting and analyzing PAHs in in situ planetary exploration.

The computer program (CAN 2) described in this report is one of several related programs used in the New Mexico District cost-analysis system. The work-effort information used in these programs is accumulated and entered to the nearest hour on forms completed by each employee. Tabulating cards are punched directly from these forms after visual examinations for errors are made. Reports containing detailed work-effort data itemized by employee within each project and account and by account and project for each employee are prepared for both current-month and year-to-date periods by the CAN 2 computer program. An option allowing preparation of reports for a specified 3-month period is provided. The total number of hours worked on each account and project and a grand total of hours worked in the New Mexico District is computed and presented in a summary report for each period. Work effort not chargeable directly to individual projects or accounts is considered as overhead and can be apportioned to the individual accounts and projects on the basis of the ratio of the total hours of work effort for the individual accounts or projects to the total New Mexico District work effort at the option of the user. The hours of work performed by a particular section, such as General Investigations or Surface Water, are prorated and charged to the projects or accounts within the particular section. A number of surveillance or buffer accounts are employed to account for the hours worked on special events or on those parts of large projects or accounts that require a more detailed analysis. Any part of the New Mexico District operation can be separated and analyzed in detail by establishing an appropriate buffer account. With the exception of statements associated with word size, the computer program is written in FORTRAN IV in a relatively low and standard language level to facilitate its use on different digital computers. The program has been run only on a Control Data Corporation

The impact of lean production and related new systems of work organization on worker health.

PubMed

Landsbergis, P A; Cahill, J; Schnall, P

1999-04-01

New systems of work organization, such as lean production and total quality management, have been introduced by employers throughout the industrialized world to improve productivity, quality, and profitability. However, few studies have examined the impact of such systems on occupational injuries or illnesses or on job characteristics related to job strain, which has been linked to hypertension and cardiovascular disease. The studies reviewed provide little evidence to support the hypothesis that lean production "empowers" auto workers. In fact, auto industry studies suggest that lean production creates intensified work pace and demands. Increases in decision authority and skill levels are modest or temporary, whereas decision latitude typically remains low. Thus, such work can be considered to have job strain. In jobs with ergonomic stressors, intensification of labor appears to lead to increases in musculoskeletal disorders. The evidence for adverse health effects remains inconclusive for related new work systems in other industries, such as modular manufacturing or patient-focused care.

Development and Evaluation of a Spectral Analysis Method to Eliminate Organic Interference with Cavity Ring-Down Measurements of Water Isotope Ratios.

Lin, Z.; Kim-Hak, D.; Popp, B. N.; Wallsgrove, N.; Kagawa-Viviani, A.; Johnson, J.

2017-12-01

Cavity ring-down spectroscopy (CRDS) is a technology based on the spectral absorption of gas molecules of interest at specific spectral regions. The CRDS technique enables the analysis of hydrogen and oxygen stable isotope ratios of water by directly measuring individual isotopologue absorption peaks such as H16OH, H18OH, and D16OH. Early work demonstrated that the accuracy of isotope analysis by CRDS and other laser-based absorption techniques could be compromised by spectral interference from organic compounds, in particular methanol and ethanol, which can be prevalent in ecologically-derived waters. There have been several methods developed by various research groups including Picarro to address the organic interference challenge. Here, we describe an organic fitter and a post-processing algorithm designed to improve the accuracy of the isotopic analysis of the "organic contaminated" water specifically for Picarro models L2130-i and L2140-i. To create the organic fitter, the absorption features of methanol around 7200 cm-1 were characterized and incorporated into spectral analysis. Since there was residual interference remaining after applying the organic fitter, a statistical model was also developed for post-processing correction. To evaluate the performance of the organic fitter and the postprocessing correction, we conducted controlled experiments on the L2130-i for two water samples with different isotope ratios blended with varying amounts of methanol (0-0.5%) and ethanol (0-5%). When the original fitter was not used for spectral analysis, the addition of 0.5% methanol changed the apparent isotopic composition of the water samples by +62‰ for δ18O values and +97‰ for δ2H values, and the addition of 5% ethanol changed the apparent isotopic composition by -0.5‰ for δ18O values and -3‰ for δ2H values. When the organic fitter was used for spectral analysis, the maximum methanol-induced errors were reduced to +4‰ for δ18O values and +5‰ for δ2

Molybdenum oxide is used as a low-resistance anode interfacial layer in applications such as organic light emitting diodes and organic photovoltaics. However, little is known about the correlation between its stoichiometry and electronic properties, such as work function and occupied gap states. In addition, despite the fact that the knowledge of the exact oxide stoichiometry is of paramount importance, few studies have appeared in the literature discussing how this stoichiometry can be controlled to permit the desirable modification of the oxide's electronic structure. This work aims to investigate the beneficial role of hydrogenation (the incorporation of hydrogen within the oxide lattice) versus oxygen vacancy formation in tuning the electronic structure of molybdenum oxides while maintaining their high work function. A large improvement in the operational characteristics of both polymer light emitting devices and bulk heterojunction solar cells incorporating hydrogenated Mo oxides as hole injection/extraction layers was achieved as a result of favorable energy level alignment at the metal oxide/organic interface and enhanced charge transport through the formation of a large density of gap states near the Fermi level.

Cognitive work analysis (CWA) as an analytical approach for examining complex sociotechnical systems has shown success in modelling the work of single operators. The CWA approach incorporates social and team interactions, but a more explicit analysis of team aspects can reveal more information for systems design. In this paper, Team CWA is explored to understand teamwork within a birthing unit at a hospital. Team CWA models are derived from theories and models of teamwork and leverage the existing CWA approaches to analyse team interactions. Team CWA is explained and contrasted with prior approaches to CWA. Team CWA does not replace CWA, but supplements traditional CWA to more easily reveal team information. As a result, Team CWA may be a useful approach to enhance CWA in complex environments where effective teamwork is required. This paper looks at ways of analysing cognitive work in healthcare teams. Team Cognitive Work Analysis, when used to supplement traditional Cognitive Work Analysis, revealed more team information than traditional Cognitive Work Analysis. Team Cognitive Work Analysis should be considered when studying teams.

The current meta-analysis shows that organic dairy products contain significantly higher protein, ALA, total omega-3 fatty acid, cis-9,trans-11 conjugated linoleic acid, trans-11 vaccenic acid, eicosapentanoic acid, and docosapentanoic acid than those of conventional types, with cumulative effect size ( ± 95% confidence interval) of 0.56 ± 0.24, 1.74 ± 0.16, 0.84 ± 0.14, 0.68 ± 0.13, 0.51 ± 0.16, 0.42 ± 0.23, and 0.71 ± 0.3, respectively. It is also observed that organic dairy products have significantly (P < 0.001) higher omega-3 to -6 ratio (0.42 vs. 0.23) and Δ9-desaturase index (0.28 vs. 0.27) than the conventional types. The current regulation on organic farming indeed drives organic farms to production of organic dairy products with different nutritional qualities from conventional ones. The differences in feeding regime between conventional and organic dairy production is suspected as the reason behind this evidence. Further identical meta-analysis may be best applicable for summarizing a comparison between conventional and organic foodstuffs for other aspects and food categories.

Long working hours, occupational health and the changing nature of work organization.

PubMed

Johnson, Jeffrey V; Lipscomb, Jane

2006-11-01

The impact of long working hours on health has been of major concern since the late 19th Century. Working hours are again increasing in the US. An overview of historical, sociological, and health-related research presented at an international conference on long working hours is discussed as an introduction to a special section in this issue. Research indicates that long working hours are polarizing along class lines with professionals working regular though longer hours and less well-educated workers having fewer though more irregular hours. Extended and irregular hours are associated with acute reactions such as stress and fatigue, adverse health behavior such as smoking, and chronic outcomes such as cardiovascular and musculoskeletal disorders. Improved methodologies are needed to track exposure to long working hours and irregular shifts longitudinally. Research should focus on the adverse impact that sleep-deprived and stressed workers may have on the health of the public they serve. A variety of protective efforts should be undertaken and evaluated. Copyright (c) 2006 Wiley-Liss, Inc.

Sex differences in visual-spatial working memory: A meta-analysis.

PubMed

Voyer, Daniel; Voyer, Susan D; Saint-Aubin, Jean

2017-04-01

Visual-spatial working memory measures are widely used in clinical and experimental settings. Furthermore, it has been argued that the male advantage in spatial abilities can be explained by a sex difference in visual-spatial working memory. Therefore, sex differences in visual-spatial working memory have important implication for research, theory, and practice, but they have yet to be quantified. The present meta-analysis quantified the magnitude of sex differences in visual-spatial working memory and examined variables that might moderate them. The analysis used a set of 180 effect sizes from healthy males and females drawn from 98 samples ranging in mean age from 3 to 86 years. Multilevel meta-analysis was used on the overall data set to account for non-independent effect sizes. The data also were analyzed in separate task subgroups by means of multilevel and mixed-effects models. Results showed a small but significant male advantage (mean d = 0.155, 95 % confidence interval = 0.087-0.223). All the tasks produced a male advantage, except for memory for location, where a female advantage emerged. Age of the participants was a significant moderator, indicating that sex differences in visual-spatial working memory appeared first in the 13-17 years age group. Removing memory for location tasks from the sample affected the pattern of significant moderators. The present results indicate a male advantage in visual-spatial working memory, although age and specific task modulate the magnitude and direction of the effects. Implications for clinical applications, cognitive model building, and experimental research are discussed.

Speleothems preserve organic matter that is derived from both the surface soil and cave environments. This organic matter can be used to understand paleoclimate and paleoenvironments. However, a stable and quick micro-analysis method to measure the δ13C signals from speleothem organic matter separate from the total δ13C remains absent. And speleothem organic geochemistry is still relatively unexplored compared to inorganic geochemistry. In this research, for the organic matter analysis, bulk homogeneous power samples were obtained from one large stalagmite. These were dissolved by phosphoric acid to produce the aqueous solution. Then, the processed solution was degassed through a rotational vacuum concentrator. A liquid chromatograph was coupled to IRMS to control the oxidization and the measurement of analytes. This method is demonstrated to be robust for the analysis of speleothem d13C organic matter analysis under different preparation and instrumental settings, with the low standard deviation ( 0.2‰), and low sample consumption (<25 mg). Considering the complexity of cave environments, this method will be useful in further investigations the δ13C of entrapped organic matter and environmental controls in other climatic and ecological contexts, including the determination of whether vegetation or soil microbial activity is the dominant control on speleothem d13C of organic matter.

Coordinated partnerships and collaborations can optimize the efficiency and effectiveness of service and program delivery in organizational networks. However, the extent to which organizations are working together to promote physical activity, and use physical activity policies in Canada, is unknown. This project sought to provide a snapshot of the funding, coordination and partnership relationships among provincial active living organizations (ALOs) in Alberta, Canada. Additionally, the awareness, and use of the provincial policy and national strategy by the organizations was examined. Provincial ALOs (N = 27) answered questions regarding their funding, coordination and partnership connections with other ALOs in the network. Social network analysis was employed to examine network structure and position of each ALO. Discriminant function analysis determined the extent to which degree centrality was associated with the use of the Active Alberta (AA) policy and Active Canada 20/20 (AC 20/20) strategy. The funding network had a low density level (density = .20) and was centralized around Alberta Tourism Parks and Recreation (ATPR; degree centralization = 48.77%, betweenness centralization = 32.43%). The coordination network had a moderate density level (density = .31), and was low-to-moderately centralized around a few organizations (degree centralization = 45.37%, betweenness centrality = 19.92%). The partnership network had a low density level (density = .15), and was moderate-to-highly centralized around ATPR. Most organizations were aware of AA (89%) and AC 20/20 (78%), however more were using AA (67%) compared to AC 20/20 (33%). Central ALOs in the funding network were more likely to use AA and AC 20/20. Central ALOs in the coordination network were more likely to use AC 20/20, but not AA. Increasing formal and informal relationships between organizations and integrating disconnected or peripheral organizations could increase the capacity of the

Work System analysis and design is complex and non-deterministic. In this paper we describe Brahms, a multiagent modeling and simulation environment for designing complex interactions in human-machine systems. Brahms was originally conceived as a business process design tool that simulates work practices, including social systems of work. We describe our modeling and simulation method for mission operations work systems design, based on a research case study in which we used Brahms to design mission operations for a proposed discovery mission to the Moon. We then describe the results of an actual method application project-the Brahms Mars Exploration Rover. Space mission operations are similar to operations of traditional organizations; we show that the application of Brahms for space mission operations design is relevant and transferable to other types of business processes in organizations.

In this work, different analytical techniques (thermal analysis, (13)C cross-polarization magic angle spinning (CPMAS) NMR and Fourier transform infrared (FT-IR) spectroscopy) have been used to study the organic matter changes during the co-composting of pig slurry with cotton gin waste. To ensure the validity of the findings, the composting process was developed in different scenarios: under experimental pilot plant conditions, using the static pile system, and under real conditions on a pig farm, using the turning pile system. Also, the thermal stability index (R1) was determined before and after an extraction with water, to evaluate the effect of eliminating water-soluble inorganic salts on the thermal analysis. The results of the thermal methods showed the degradation of the most labile organic matter during composting; R1 increased during composting in all piles, without any influence of the presence of water-soluble inorganic ions in the sample. The NMR showed a decrease in the abundance of the carbohydrate molecules and an increase in the aliphatic materials during composting, due to a concentration effect. Also, FT-IR spectroscopy was a useful technique to study the trends of polysaccharides and nitrate, as indicators of organic matter transformations during composting.

Leader Narcissism and Outcomes in Organizations: A Review at Multiple Levels of Analysis and Implications for Future Research

PubMed Central

Braun, Susanne

2017-01-01

Narcissists often pursue leadership and are selected for leadership positions by others. At the same time, they act in their own best interest, putting the needs and interests of others at risk. While theoretical arguments clearly link narcissism and leadership, the question whether leader narcissism is good or bad for organizations and their members remains unanswered. Narcissism seems to have two sides, a bright and a dark one. This systematic literature review seeks to contribute to the ongoing academic discussion about the positive or negative impact of leader narcissism in organizations. Forty-five original research articles were categorized according to outcomes at three levels of analysis: the dyadic level (focusing on leader-follower relationships), the team level (focusing on work teams and small groups), and the organizational level. On this basis, we first summarized the current state of knowledge about the impact that leader narcissism has on outcomes at different levels of analysis. Next, we revealed similarities and contradictions between research findings within and across levels of analysis, highlighting persistent inconsistencies concerning the question whether leader narcissism has positive or negative consequences. Finally, we outlined theoretical and methodological implications for future studies of leader narcissism. This multi-level perspective ascertains a new, systematic view of leader narcissism and its consequences for organizations and their stakeholders. The article demonstrates the need for future research in the field of leader narcissism and opens up new avenues for inquiry. PMID:28579967

Night Shift Work and Risk of Depression: Meta-analysis of Observational Studies

PubMed Central

2017-01-01

This study aimed to assess whether night shift work is associated with the risk of depression by using a meta-analysis of observational studies. We searched PubMed and EMBASE in August, 2016 to locate eligible studies and investigated the association between night shift work and the risk of depression, reporting outcome measures with adjusted odds ratios (ORs) or relative risks (RRs) and 95% confidence intervals (CIs). In the meta-analysis of a total of 11 observational studies with 9 cross-sectional study, 1 longitudinal study, and 1 cohort study, night shift work was significantly associated with an increased risk of depression (OR/RR, 1.43; 95% CI, 1.24–1.64; I2 = 78.0%). Also, subgroup meta-analyses by gender, night shift work duration, type of occupation, continent, and type of publication showed that night shift work was consistently associated with the increased risk of depression. The current meta-analysis suggests that night shift work is associated with the increased risk of depression. However, further large prospective cohort studies are needed to confirm this association.

Mixture of hydrocarbon and carbon dioxide shows excellent cycle performance in Organic Rankine Cycle (ORC) used for engine waste heat recovery, but the unavoidable leakage in practical application is a threat for safety due to its flammability. In this work, a quantitative risk assessment system (QR-AS) is established aiming at providing a general method of risk assessment for flammable working fluid leakage. The QR-AS covers three main aspects: analysis of concentration distribution based on CFD simulations, explosive risk assessment based on the TNT equivalent method and risk mitigation based on evaluation results. A typical case of propane/carbon dioxide mixture leaking from ORC is investigated to illustrate the application of QR-AS. According to the assessment results, proper ventilation speed, safe mixture ratio and location of gas-detecting devices have been proposed to guarantee the security in case of leakage. The results revealed that this presented QR-AS was reliable for the practical application and the evaluation results could provide valuable guidance for the design of mitigation measures to improve the safe performance of ORC system.

Jin, Lei; Zhang, Jiang; Tan, Gangfeng; Liu, Huaming

2017-07-01

The organic Rankine cycle (ORC) is an effective way to recovery the engine exhaust heat. The thermal stability of the evaporation system is significant for the stable operation of the ORC system. In this paper, the performance of the designed evaporation system which combines with the intermediate fluid for recovering the exhaust waste heat from a diesel engine is evaluated. The thermal characteristics of the target diesel engine exhaust gas are evaluated based on the experimental data firstly. Then, the mathematical model of the evaporation system is built based on the geometrical parameters and the specific working conditions of ORC. Finally, the heat transfer characteristics of the evaporation system are estimated corresponding to three typical operating conditions of the diesel engine. The result shows that the exhaust temperature at the evaporator outlet increases slightly with the engine speed and load. In the evaporator, the heat transfer coefficient of the Rankine working fluid is slightly larger than the intermediate fluid. However, the heat transfer coefficient of the intermediate fluid in the heat exchanger is larger than the exhaust side. The heat transfer areas of the evaporator in both the two-phase zone and the preheated zone change slightly along with the engine working condition while the heat transfer areas of the overheated zone has changed obviously. The maximum heat transfer rate occurs in the preheating zone while the minimum value occurs in the overheating zone. In addition, the Rankine working fluid temperature at the evaporator outlet is not sensitively affected by the torque and speed of the engine and the organic fluid flow is relatively stable. It is concluded that the intermediate fluid could effectively reduce the physical changes of Rankine working fluid in the evaporator outlet due to changes in engine operating conditions.

To determine the capacity and development needs, in relation to key areas of competency and skills, of the specialist public health workforce based in primary care organizations following the 2001 restructuring of the UK National Health Service. Questionnaire survey to all consultants and specialists in public health (including directors of public health) based in primary care trusts (PCTs) and strategic health authorities (SHAs) in England. Participants reported a high degree of competency. However, skill gaps were evident in some areas of public health practice, most notably "developing quality and risk management" and in relation to media communication, computing, management and leadership. In general, medically qualified individuals were weaker on community development than non-medically qualified specialists, and non-medically qualified specialists were less able to perform tasks that require epidemiological or clinical expertise than medically qualified specialists. Less than 50% of specialists felt that their links to external organizations, including public health networks, were strong. Twenty-nine percent of respondents felt professionally isolated and 22% reported inadequate team working within their PCT or SHA. Approximately 21% of respondents expressed concerns that they did not have access to enough expertise to fulfil their tasks and that their skills were not being adequately utilized. Some important skill gaps are evident among the specialist public health workforce although, in general, a high degree of competency was reported. This suggests that the capacity deficit is a problem of numbers of specialists rather than an overall lack of appropriate skills. Professional isolation must be addressed by encouraging greater partnership working across teams.

Professional burnout and work satisfaction in Spanish allergists: analysis of working conditions in the specialty.

Burnout is a worrying problem in the medical profession and has proven to be highly prevalent in all the care settings and specialty areas in which it has been studied.We applied 2 widely used questionnaires to analyze the working conditions of Spanish allergists in terms of quality of professional life and degree of burnout perceived. Participants completed 2 questionnaires: the 22-item Maslach scale, a structured questionnaire covering different aspects of the feelings and attitudes of professionals toward their work and patients; and the Spanish Quality of Professional Life Questionnaire (CPV-35), a 35-item questionnaire evaluating job satisfaction and perceived quality of life at work. We received 404 questionnaires from throughout Spain. The main sources of motivation were better pay (94.4%), more available resources/technology (85.1%), access to research activities (81%), and promotion in one's professional career (80.1%). Analysis of the scores from the Maslach scale revealed that two-thirds of the allergists interviewed experienced medium and high levels of negative burnout (67.9% and 66.2%, respectively, for emotional exhaustion and depersonalization). This situation was in part compensated for by the fact that a slightly lower proportion of the group (59.2%) obtained very high scores on personal accomplishment in their work. Analysis of the scores from the CPV-35 questionnaire revealed 3 complementary aspects of job satisfaction: perceptions of the workload borne (5.8), management support available to cope with daily patient workload (5.6), and levels of intrinsic motivation for work (7.7), which was the highest value. The score for the item summarizing self-perceived overall quality of working life was acceptable (6.4). Promoting intrinsic motivation of Spanish allergists using the motivating factors identified in this study could protect against professional burnout.

Orthopedic resident work-shift analysis: are we making the best use of resident work hours?

Surgery programs have been tasked to meet rising demands in patient surgical care while simultaneously providing adequate resident training in the midst of increasing resident work-hour restrictions. The purpose of this study was to quantify orthopedic surgery resident workflow and identify areas needing improved resident efficiency. We hypothesize that residents spend a disproportionate amount of time involved in activities that do not relate directly to patient care or maximize resident education. We observed 4 orthopedic surgery residents on the orthopedic consult service at a major tertiary care center for 72 consecutive hours (6 consecutive shifts). We collected minute-by-minute data using predefined work-task criteria: direct new patient contact, direct existing patient contact, communications with other providers, documentation/administrative time, transit time, and basic human needs. A seventh category comprised remaining less-productive work was termed as standby. In a 720-minute shift, residents spent on an average: 191 minutes (26.5%) performing documentation/administrative duties, 167.0 minutes (23.2%) in direct contact with new patient consults, 129.6 minutes (17.1%) in communication with other providers regarding patients, 116.2 (16.1%) minutes in standby, 63.7 minutes (8.8%) in transit, 32.6 minutes (4.5%) with existing patients, and 20 minutes (2.7%) attending to basic human needs. Residents performed an additional 130 minutes of administrative work off duty. Secondary analysis revealed residents were more likely to perform administrative work rather than directly interact with existing patients (p = 0.006) or attend to basic human needs (p = 0.003). Orthopedic surgery residents spend a large proportion of their time performing documentation/administrative-type work and their workday can be operationally optimized to minimize nonvalue-adding tasks. Formal workflow analysis may aid program directors in systematic process improvements to better align

Spatially Resolved, In Situ Carbon Isotope Analysis of Archean Organic Matter

Spatiotemporal variability in the carbon isotope composition of sedimentary organic matter (OM) preserves information about the evolution of the biosphere and of the exogenic carbon cycle as a whole. Primary compositions, and imprints of the post-depositional processes that obscure them, exist at the scale of individual sedimentary grains (mm to micron). Secondary ion mass spectrometry (SIMS) (1) enables analysis at these scales and in petrographic context, (2) permits morphological and compositional characterization of the analyte and associated minerals prior to isotopic analysis, and (3) reveals patterns of variability homogenized by bulk techniques. Here we present new methods for in situ organic carbon isotope analysis with sub-permil precision and spatial resolution to 1 micron using SIMS, as well as new data acquired from a suite of Archean rocks. Three analytical protocols were developed for the CAMECA ims1280 at WiscSIMS to analyze domains of varying size and carbon concentration. Average reproducibility (at 2SD) using a 6 micron spot size with two Faraday cup detectors was 0.4 %, and 0.8 % for analyses using 1 micron and 3 micron spot sizes with a Faraday cup (for C-12) and an electron multiplier (for C-13). Eight coals, two ambers, a shungite, and a graphite were evaluated for micron-scale isotopic heterogeneity, and LCNN anthracite (delta C-13 = -23.56 +/- 0.1 %, 2SD) was chosen as the working standard. Correlation between instrumental bias and H/C was observed and calibrated for each analytical session using organic materials with H/C between 0.1 and 1.5 (atomic), allowing a correction based upon a C-13H/C-13 measurement included in every analysis. Matrix effects of variable C/SiO2 were evaluated by measuring mm to sub-micron graphite domains in quartzite from Bogala mine, Sri Lanka. Apparent instrumental bias and C-12 count rate are correlated in this case, but this may be related to a crystal orientation effect in graphite. Analyses of amorphous

This study demonstrated possible relationships between environmental, personal, and occupational factors and changes in the subjective health symptoms of 214 employees after the relocation of a hospital in a region of Japan. Eight indoor volatile organic compounds (VOCs) were detected in at least one of the 19 rooms investigated, and total VOC (TVOC) concentrations in 8 rooms exceeded the advisable value (400 microg/m(3)) established by the Ministry of Health, Labour and Welfare of Japan. Formaldehyde was detected in all the investigated rooms, but none of the results exceeded the guideline value (100 microg/m(3)). Multiple logistic regression analysis was applied to select variables significantly associated with the subjective symptoms that can be induced by sick building syndrome. The results showed that subjective symptoms of deterioration in the skin, eye, ear, throat, chest, central nervous system, autonomic system, musculoskeletal system, and digestive system among employees were associated mainly with gender difference and high TVOC concentrations (>1200 microg/m(3)). Long work hours (>50 h per week) in females and smoking in males were to be blamed for the deterioration of their symptoms. The present findings suggest that to protect employees from indoor environment-related adverse health effects, it is necessary to reduce the concentration of indoor chemicals in new buildings, to decrease work hours, and to forbid smoking.

2011-01-01

The search for extra-terrestrial life starts at home. In order to find life on other planets, we start by examining life processes we understand on the earth. Though it may not be possible to see the life in the form of macroscopic organisms, telltale signs of life can exist in the form of small organic molecules such as peptides and amino acids. Our overall goal is to test a portable mass spectrometer (MS) system, the Mini 10.5, for astrobiological applications including in situ hydrocarbon analysis and sediments analysis using an additional automated sample processing system (ASPS). The collaborative research focuses on two current projects in the field of astrobiology. Both projects are geared towards examining organics distributed in extreme environments. One portion of study attempts to qualitatively analyze the effect of volatile organic compounds (VOC) produced by diesel exhaust on lichens growing in the desert. This requires measurements to be taken by bringing the instrument to the Mojave Desert and monitoring atmospheric composition of VOCs in situ. The second project is to evaluate the miniature MS system as a detector for the ASPS extraction system. A major obstacle of any chemometric in situ analysis is the suppression of analyte signal by concomitant signal from the surrounding environment. The ASPS extraction device has been developed at JPL to extract amino acids from sediment samples and elute them in solution. The solution is eluted at a high pH and needs to be conditioned to a more neutral pH so that dissolved amino acids can be readily protonated and subsequently analyzed by electrospray MS.

This study investigated the psychometric properties of the Work/Life Balance Self-Assessment scale among nurse faculty involved in doctoral education. A national random sample of 554 respondents completed the Work/Life Balance Self-Assessment scale, which addresses 3 factors: work interference with personal life (WIPL), personal life interference with work (PLIW), and work/personal life enhancement (WPLE). A principal components analysis with varimax rotation revealed 3 internally consistent aspects of work-life balance, explaining 40.5% of the variance. The Cronbach's alpha coefficients for reliability of the scale were .88 for the total scale and for the subscales, .93 (WIPL), .85 (PLIW), and .69 (WPLE). The Work/Life Balance Self-Assessment scale appears to be a reliable and valid instrument to examine work-life balance among nurse faculty.

The (im)possibilities of returning to work after a stroke.

Norstedt, Maria

2017-01-01

What a stroke means for working-age persons has not been sufficiently studied from a sociological perspective. This article uses the empirical material of a larger study to describe and analyze how institutional practices and discourses influence attempts to return to work after a stroke. Semi-structured interviews were conducted with ten persons who have had a stroke and ten civil servants and professionals from the Swedish Public Employment Service, the Social Insurance Agency, and different health care institutions. The qualitative analysis was inspired by institutional ethnography. The analysis shows how persons who have had a stroke and civil servants and professionals in welfare organizations share the same goal: a return to working life for the former. The persons in this study related to, translated, and put into practice discourses of normality and employability in this process. However, there were, at times, conflicting institutional practices between the different organizations. Conflicting institutional practices connected to the discourses of normality and employability contribute to the difficulties that persons who have had a stroke face when trying to return to work after recovery.

Optimizing performance on work activities and processes requires metrics of performance for management to monitor and analyze in order to support further improvements in efficiency, effectiveness, safety, reliability and cost. Information systems are therefore required to assist management in making timely, informed decisions regarding these work processes and activities. Currently information systems regarding Space Shuttle maintenance and servicing do not exist to make such timely decisions. The work to be presented details a system which incorporates various automated and intelligent processes and analysis tools to capture organize and analyze work process related data, to make the necessary decisions to meet KSC organizational goals. The advantages and disadvantages of design alternatives to the development of such a system will be discussed including technologies, which would need to bedesigned, prototyped and evaluated.

A fundamental challenge in immunology is to decipher the principles governing immune responses at the whole-organism scale. Here, using a comparative infection model, we observe immune signal propagation within and between organs to obtain a dynamic map of immune processes at the organism level. We uncover two inter-organ mechanisms of protective immunity mediated by soluble and cellular factors. First, analyzing ligand-receptor connectivity across tissues reveals that type I IFNs trigger a whole-body antiviral state, protecting the host within hours after skin vaccination. Second, combining parabiosis, single-cell analyses, and gene knockouts, we uncover a multi-organ web of tissue-resident memory T cells that functionally adapt to their environment to stop viral spread across the organism. These results have implications for manipulating tissue-resident memory T cells through vaccination and open up new lines of inquiry for the analysis of immune responses at the organism level.

Innes, W. B.

Sensors involving a vanadia-alumina catalyst bed-thermocouple assembly satisfy requirements for simple, reproducible and rapid continuous analysis or reactive organics. Responses generally increase with temperature to 400 C and increase to a maximum with flow rate/catalyst volume. Selectivity decreases with temperature. Response time decreases with flow rate and increases with catalyst volume. At chosen optimum conditions calculated response which is additive and linear agrees better with photochemical reactivity than other methods for various automotive sources, and response to vehicle exhaust is insensitive to flow rate. Application to measurement of total reactive organics in vehicle exhaust as well as for gas chromatography detection illustrate utility. The approach appears generally applicable to high thermal effect reactions involving first order kinetics.

Interfacial layers play a critical role in building up the Ohmic contact between electrodes and functional layers in organic photovoltaic (OPV) solar cells. These layers are based on either inorganic oxides (ZnO and TiO 2 ) or water-soluble organic polymers such as poly[(9,9-dioctyl-2,7-fluorene)-alt-(9,9-bis(3'-(N,N-dimethylamino)propyl)-2,7-fluorene)] and polyethylenimine ethoxylated (PEIE). In this work, we have developed a series of novel poly(ionic liquid) nonconjugated block copolymers for improving the performance of inverted OPV cells by using them as work function modifiers of the indium tin oxide (ITO) cathode. Four nonconjugated polyelectrolytes (n-CPEs) based on polystyrene and imidazolium poly(ionic liquid) (PSImCl) were synthesized by reversible addition-fragmentation chain transfer polymerization. The ratio of hydrophobic/hydrophilic block copolymers was varied depending on the ratio of polystyrene to the PSImCl block. The ionic density, which controls the work function of the electrode by forming an interfacial dipole between the electrode and the block copolymers, was easily tuned by simply changing the PSImCl molar ratio. The inverted OPV device with the ITO/PS 29 -b-PSImCl 60 cathode achieved the best power conversion efficiency (PCE) of 7.55% among the synthesized block copolymers, exhibiting an even higher PCE than that of the reference OPV device with PEIE (7.30%). Furthermore, the surface properties of the block copolymers films were investigated by contact angle measurements to explore the influence of the controlled hydrophobic/hydrophilic characters on the device performances.

Formulation of work stress in 1960-2000: analysis of scientific works from the perspective of historical sociology.

During the latter part of the 20th century, work stress became an important societal issue and a huge amount of scientific attention went to studying it. This paper examines the process of formulating and defining the concept of work stress in the occupational health sciences and in industrial and organizational psychology from the early 1960s to the late 1990s. The empirical material of the study encompasses 108 scientific articles, books, book chapters, 'state of the art' reviews, book reviews, and written conference presentations. The data are analysed in the frameworks of historical sociology, critical psychology, and the anthropology of knowledge. We argue that work stress as a life-structuring concept gained ground in psychosocial and occupational health sciences (and also in lay understanding) in the 1960s simultaneously with the rise of social reformist movements that called for fundamental changes emphasizing democratic and human-orientated work organizations and socially responsible values. With the passing of time, however, the focus on structural improvement of work life waned and the emphasis shifted towards the apolitical occupational health aspects of work stress. Researchers with a psychological orientation emphasized micro-level characteristics as factors affecting work stress, whereas stress-orientated epidemiologists turned to the study of specific occupational stress models and/or risk factors. The emergence and development of work stress research can be seen as a chain of attempts to define and identify new risks and experiences occurring in work life. The process, driven by a gradual shift from industrial environments towards organizational frameworks characterized by social and psychological dimensions, reflected the overall shift towards modern democratic work life and the information society in which employees' emotions and well-being became an issue.

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

2016-01-01

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.

Re: Madsen et al. "Unnecessary work tasks and mental health: a prospective analysis of Danish human service workers".

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

This study aimed to assess whether night shift work is associated with the risk of depression by using a meta-analysis of observational studies. We searched PubMed and EMBASE in August, 2016 to locate eligible studies and investigated the association between night shift work and the risk of depression, reporting outcome measures with adjusted odds ratios (ORs) or relative risks (RRs) and 95% confidence intervals (CIs). In the meta-analysis of a total of 11 observational studies with 9 cross-sectional study, 1 longitudinal study, and 1 cohort study, night shift work was significantly associated with an increased risk of depression (OR/RR, 1.43; 95% CI, 1.24-1.64; I² = 78.0%). Also, subgroup meta-analyses by gender, night shift work duration, type of occupation, continent, and type of publication showed that night shift work was consistently associated with the increased risk of depression. The current meta-analysis suggests that night shift work is associated with the increased risk of depression. However, further large prospective cohort studies are needed to confirm this association. © 2017 The Korean Academy of Medical Sciences.

[Purpose] This study was conducted to provide basic data for solutions to reduce the turnover rate of physical therapists. It should help create efficient personnel and organization management by exploring the impact of the work environment and work-related stress on turnover intention and analyzing the correlation between them. [Subjects and Methods] A survey was conducted with 236 physical therapists working at medical institutions in the Daejeon and Chungcheong areas. For the analysis on the collected data, correlational and linear regression analyses were conducted using the SPSS 18.0 program and Cronbach's alpha coefficient. [Results] The results showed a statistically significant positive correlation between turnover intention and work-related stress but a statistically significant negative correlation respectively between turnover intention and work environment. Work-related stress (β=0.415) had a significant positive impact on turnover intention and work environment (β=-0.387) had a significant negative impact on turnover intention. [Conclusion] To increase satisfaction level with the profession as well as the workplace for physical therapists, improvement of the work environment was the most necessary primary improvement.

Two chemically distinct light-absorbing pools of urban organic aerosols: A comprehensive multidimensional analysis of trends.

Paula, Andreia S; Matos, João T V; Duarte, Regina M B O; Duarte, Armando C

2016-02-01

The chemical and light-absorption dynamics of organic aerosols (OAs), a master variable in the atmosphere, have yet to be resolved. This study uses a comprehensive multidimensional analysis approach for exploiting simultaneously the compositional changes over a molecular size continuum and associated light-absorption (ultraviolet absorbance and fluorescence) properties of two chemically distinct pools of urban OAs chromophores. Up to 45% of aerosol organic carbon (OC) is soluble in water and consists of a complex mixture of fluorescent and UV-absorbing constituents, with diverse relative abundances, hydrophobic, and molecular weight (Mw) characteristics between warm and cold periods. In contrast, the refractory alkaline-soluble OC pool (up to 18%) is represented along a similar Mw and light-absorption continuum throughout the different seasons. Results suggest that these alkaline-soluble chromophores may actually originate from primary OAs sources in the urban site. This work shows that the comprehensive multidimensional analysis method is a powerful and complementary tool for the characterization of OAs fractions. The great diversity in the chemical composition and optical properties of OAs chromophores, including both water-soluble and alkaline-soluble OC, may be an important contribution to explain the contrasting photo-reactivity and atmospheric behavior of OAs.

Stanton, Neville A; Bessell, Kevin

2014-01-01

This paper presents the application of Cognitive Work Analysis to the description of the functions, situations, activities, decisions, strategies, and competencies of a Trafalgar class submarine when performing the function of returning to periscope depth. All five phases of Cognitive Work Analysis are presented, namely: Work Domain Analysis, Control Task Analysis, Strategies Analysis, Social Organisation and Cooperation Analysis, and Worker Competencies Analysis. Complex socio-technical systems are difficult to analyse but Cognitive Work Analysis offers an integrated way of analysing complex systems with the core of functional means-ends analysis underlying all of the other representations. The joined-up analysis offers a coherent framework for understanding how socio-technical systems work. Data were collected through observation and interviews at different sites across the UK. The resultant representations present a statement of how the work domain and current activities are configured in this complex socio-technical system. This is intended to provide a baseline, from which all future conceptions of the domain may be compared. The strength of the analysis is in the multiple representations from which the constraints acting on the work may be analysed. Future research needs to challenge the assumptions behind these constraints in order to develop new ways of working. Copyright © 2013 Elsevier Ltd and The Ergonomics Society. All rights reserved.
