Exposure assessment in different occupational groups at a hospital using Quick Exposure Check (QEC) - a pilot study

In order to test the feasibility and sensitivity of the ergonomic exposure assessment tool Quick Exposure Check (QEC), a pilot-study was conducted. The aim was to test QEC in different occupational groups to compare the exposure in the most common work task with the exposure in the work task perceived as the most strenuous for the neck/shoulder region, and to test intra-observer reliability. One experienced ergonomist observed 23 workers. The mean observation time was 45 minutes, waiting time and time for complementary questions included. The exposure scores varied between the different occupational groups as well as between workers within the occupational groups. Eighteen workers rated their most common work task as also being the most strenuous for the neck/shoulder region. For the remaining five workers, the mean exposure score were higher both for the neck and shoulder/arm in the most common work task. Intra-observer reliability shows agreement in 86% of the exposure interactions in the neck and in 71% in the shoulder/arm. QEC seems to fulfill the expectations of being a quick, sensible and practical exposure assessment tool that covers physical risk factors in the neck, upper extremities and low back.

Ergonomic risks in mining companies: a study in Paraiba/Brazil

The growing concern for the welfare of workers in the work environment, the importance of widespread use of ergonomics in the different sectors of industry. Yet most corporate practices that work with rudimentary or great need for human handling of materials is not fully in line with the ergonomic aspects. Given this, this article aims to identify ergonomic hazards in mining to later propose improvements in the process. After a series conducted plant visits, found that workers are exposed to various ergonomic risks, which entails the need for new healthy practices in the workplace. Finally, a series of proposals are submitted in order to avoid possible occupational diseases.     

Study and analysis of occupational risk factors for ergonomic design of construction worksystems

Manual material handling (MMH) is unavoidable because of the nature of jobs or tasks as and man-machine interfaces in a construction worksystem. Data were collected from six strata of workers viz., masons, mason helpers, carpenters, welders, gas cutters and ground-level helpers (259 out of 700 workers) from a construction site of a steel plant located in India to analyze different types of occupational risk factors, such as awkward posture, repetitive movements and others associated with MMH activities to assess their impact on musculoskeletal disorders (MSDs). It is essential that these risk factors are required to be under control through application of ergonomics-based design approaches for construction worksystem. In this context, multinomial logistic regression analyses were used to identify the significant risk factors among the workers. The results shows that masons, mason helpers, carpenters, welders/gas cutters and ground-level helpers are greatly affected by static body posture, type of tools used, excessive stress due to repetition, awkward postures and extreme climate, respectively. Appropriate preventive and corrective measures are suggested for minimization of risks associated with such jobs/tasks to improve health and performance of the workers.     

How can We Enhance Productivity in Social Work? Dynamically Reflective Structures,Dialogic Leadership and the Development of Transformative Expertise

This article examines how to enhance the ability of managers to promote productivity through reflective structures and appreciatively evaluative dialogues based on front-line expertise and knowledge in social work practice. In order to discuss these ideas, we review the ideas of dialogical leadership and reflective structures, and the concept of productivity in relation to reassessing social work core tasks and the work-related well-being of social workers. We will present and reflect on our experiences and ideas generated from research that developed reflective tools, known as the Mirror method, for peer evaluation and practice development in social work. The Mirror method is designed as a tool for leaders and managers to enhance, through trialogic processes and structures, both the well-being of employees at the individual level and the productivity of social work and learning for transformation at the organizational level.     

Supporting students to use social media and comply with professional standards

Student social workers live in a world where sharing of information seems to be straightforward and unproblematic. However, data sharing is a contentious issue in practice that raises ethical issues. There is a focus on this aspect of practice in social work education particularly in the context of data storage, confidentiality and multi-disciplinary work. There have been examples of qualified workers being sanctioned by the Health Care Professions Council for breaching professional standards related to inappropriate use of social media. Understanding the advantages and potential pitfalls of social media is crucial for social workers. The aim of this research was to develop an understanding about how student social workers use social media during their time at university as a tool for continuing professional development whilst balancing the need to present a professional persona. This paper reports on four themes that emerged from a study that considered social media and social work training: changing/securing profiles; using social media to support learning and development; university support; replicating earlier behaviour in the professional setting. The findings suggest student social workers are ambivalent about the use of social media both during training and as a way to support ongoing development beyond the university setting.     

Sociodemographic Determinants of Occupational Risks of Exposure to COVID‐19 in Canada

The activities performed by Canadian workers in some occupations may increase the risk of exposure to infectious diseases such as COVID‐19. This research note explores how occupational exposure risks vary by labor force characteristics using publicly available Canadian data in combination with a data set providing information on the level of physical proximity and frequency of exposure to infections or diseases faced by workers in different occupations. The results show important sociodemographic differences. First, women work in occupations associated with significantly higher average risks of exposure to COVID‐19 than men. This is driven by their overrepresentation in high‐risk broad occupational categories such as health occupations. Second, older workers (65 years or more), a group vulnerable to COVID‐19, appear to work in occupations requiring performing activities characterized by a lower level of physical proximity than their younger colleagues, with minimal differences in the frequency of exposure to diseases or infections. Finally, workers in low‐income occupations are employed in occupations that put them at greater risk of exposure to COVID‐19 than other workers. This is especially the case for women, immigrants, and members of visible minority groups in low‐income occupations. More broadly, this research note provides insights into the health‐related dimension of the literature on occupational tasks and labor market stratification.     

Analysis of organizational conditions for risk management: the case study of a petrochemical site

This paper presents an ergonomic intervention in the petrochemical sector. The scheduled shutdown of one of the gas production sites has led the management to reduce the number of personnel on site, and then to get new recruits and experienced technicians from other sites as the policy for leaving personnel had not been properly planned, resulting in understaffing on site. Workers with seniority on the site, and who are also the most experienced do not accept the way newcomers are induced on site, whereas the management accuses them of resisting change. The intervention consisted in reconnecting local and corporate management through making the work activity visible and linking two sets of data that they held separately. Different types of analyses were made, work demography, decision making processes and tools used by the management, analysis of the building of career and work logics. Those different levels of analysis are gathered in macro-ergonomics, while showing the possible combinations between top down and bottom up approaches. The intervention resulted in concrete changes: HR simulation tool, training organisation, feedback.     

The Application of Artificial Neural Networks for Outcome Prediction in a Cohort of Severely Mentally Ill Outpatients

SUMMARY

Social workers and other mental health workers lack clinical decision support tools to predict which clients are at greatest risk of psychiatric rehospitalization. Artificial neural networks (ANNs), are computer decision support tools that make prediction and classification decisions based on accumulated experience and information contained in successfully solved cases (correct decisions). This study evaluates the use of ANNs in predicting rehospitalization of severely mentally ill outpatients. Eight Bayesian ANN models achieved correct prediction rates ranging from 75% to 93% for two prediction conditions. These results support the utility of Bayesian ANN models in the development of clinical decision support tools.     

Summary report of action research on occupational rehabilitation and community re-integration of migrant workers with work injuries in Mainland China

This article is a summary of an action research exploring the strategies to initiate the occupational rehabilitation and community re-integration of migrant workers with work injuries in Guangdong Province, China. Using two cases of rehabilitation intervention for workers with work injury, a case management model of occupational rehabilitation and community re-integration was illustrated, in the different phases of rehabilitation. Finally, some key elements in supporting occupational rehabilitation and community re-integration for migrant workers with work injury in China were highlighted.     

Forging an Identity as a Newly Qualified Worker in the Non-government Community Services Sector

Forging a professional identity is commonly assumed to be a key objective for new graduates transitioning to work. However, the extant literature on professional identity development gives minimal consideration to the role of contemporary work conditions such as increased contract-based employment and occupational instability in carving out a work identity. These workforce trends are particularly pronounced in the non-government community services sector, where worker mobility is high and workers often occupy roles that are not profession-specific. In light of these trends, this article seeks to broaden existing understandings of professional identity development. Focus groups were conducted with 24 newly qualified workers with degree-level qualifications in social work and the human services employed in the community services sector in Queensland. The findings suggest that these workers held a variety of allegiances, which were not necessarily aligned with a profession but instead shaped by the interplay of personal, professional, and organisational factors.     

Statistical precision of categorical PATH observations of trunk posture

Background: Field studies assessing biomechanical occupational exposures frequently utilize direct observation. PATH (Postures, Activities, Tools, and Handling) is a tool for systematically observing occupational exposures during non-cyclic or long, irregular-cycle jobs. While PATH has been used in many studies, its statistical performance under different data collection strategies has not yet been investigated. The purpose of the current study was to examine this issue. Methods: Data from labourers performing the four tasks comprising a 'Jacking Pit Construction' operation was extracted from a previously collected data set. Using a probability based re-sampling bootstrap approach, categorical trunk posture exposure data was compared across nine simulated data collection strategies. Results/Conclusion: At the operational level, dispersion curves showed consistent trends of increased precision with increased sizes of the data set and curves tended to intersect at the expected value seen in the parent data set. At the task level, curves did not always follow the predicted pattern, highlighting the potential pitfalls of using PATH for infrequent tasks and the striking effect that individual workers can have on group exposure estimates of such tasks.     

Work injury rehabilitation and the tendency to return to work of workers with injuries in Mainland China

This paper aims to describe the current situation of the work injury rehabilitation system in China with its drawbacks, especially relating to the employment services for workers with injuries and bringing up the topic of the need for more work to attempt to construct a modern work injury occupational rehabilitation system: perfecting the administration mechanism of policy, establishing an occupational rehabilitation pattern with Chinese characteristics, establishing the socialization service network as the core of occupational rehabilitation and establishing a practical professional team and academic communication platform. These creative thoughts may shed light on the development of the work injury rehabilitation system as well as the return to work for workers with injuries in China.     

Adaptation of the older worker to occupational challenges

The occupational adaptation practice model guided the search for and the analysis of the literature on the older worker. The purpose of this literature review was to: identify the occupational challenges that older workers experience, determine ways in which the occupational therapist can promote the occupational adaptation of older workers, and articulate the research and policy changes implied in the model related to health and improved productivity. The analysis of the worker's personal characteristics, work tasks, and environments highlighted the types of occupational challenges that may overwhelm the older worker's adaptive capacity. Straining adaptive capacity of the older worker leads to degradation in levels of mastery. The occupational therapist and others could assist the older worker to achieve relative mastery in response to occupational challenges through ergonomic solutions, training, assistive devices, management policy, and health promotion. Combined efforts of the employer, of the occupational therapist, and of the older work to capitalize on the older worker's years of experience, existing skills, and knowledge facilitates higher job satisfaction, better performance, and an increased sense of well-being in the older worker.     

Work situation operative model MOST: linking diagnosis and intervention to improve work conditions

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

Application of digital human modeling and simulation for vision analysis of pilots in a jet aircraft: a case study

Ergonomic evaluation of visual demands becomes crucial for the operators/users when rapid decision making is needed under extreme time constraint like navigation task of jet aircraft. Research reported here comprises ergonomic evaluation of pilot's vision in a jet aircraft in virtual environment to demonstrate how vision analysis tools of digital human modeling software can be used effectively for such study. Three (03) dynamic digital pilot models, representative of smallest, average and largest Indian pilot population were generated from anthropometric database and interfaced with digital prototype of the cockpit in Jack software for analysis of vision within and outside the cockpit. Vision analysis tools like view cones, eye view windows, blind spot area, obscuration zone, reflection zone etc. were employed during evaluation of visual fields. Vision analysis tool was also used for studying kinematic changes of pilot's body joints during simulated gazing activity. From present study, it can be concluded that vision analysis tool of digital human modeling software was found very effective in evaluation of position and alignment of different displays and controls in the workstation based upon their priorities within the visual fields and anthropometry of the targeted users, long before the development of its physical prototype.     

The Social Dynamics Channelling Latina College Graduates into the Teaching Profession

Sociologists examine the persistence of occupational sex segregation in two primary ways, vertically (within occupations) and horizontally (across occupations). Feminist scholars analysing gender and race inequality within work organizations have used ‘glass escalator’ and ‘glass barriers’ to document men's experiences in occupations where women concentrate, falling under the vertical epistemology. These race and gender theories are crucial to our understanding of workplace inequities, but they only address privilege or discrimination once women have entered or try climbing the work organization. Based on interviews with 40 Latina teachers in Southern California, this paper examines the point of occupational entry, and explains why college‐educated Latinas, the daughters of working‐class Latino immigrants, are disproportionately entering the teaching profession in the United States. We suggest that Latinas are socially channelled into the teaching occupation, and show how collective family considerations inform agency and occupational decision‐making for these women, resulting in a type of glass ceiling shaped by family and social class. The paper concludes with a discussion of the implications of collective‐informed agency for future studies of upwardly mobile Latinas in the professions.     

The Role of Father’s Occupation on Intergenerational Educational and Occupational Mobility: The Case of Second‐Generation Chinese Americans in New York1

A considerable body of research has found a positive relationship between parents’ socioeconomic status and children’s educational achievement and attainment. The predictive role of parents’ socioeconomic status generally applies for most racial and ethnic groups, but that association does not always hold for groups that exhibit high levels of education, such as Asian Americans. This article considers the role of parents’ education and occupation on children’s educational and occupational attainment for Chinese Americans aged 18–32. The results corroborate the positive link between parents’ socioeconomic status and children’s educational and occupational attainments. Children of professionals command an educational and occupational advantage over children of entrepreneurs and children of manual workers. Yet, the children of entrepreneurs attend selective colleges and obtain professional occupations in proportions closely following those of the children of professionals. Although the educational attainments between the fathers who worked as entrepreneurs and those fathers engaged in manual work were comparable, it was the children of entrepreneurs who surpassed the children of manual workers with respect to educational and occupational achievement and attainment. This suggests that immigrant entrepreneurship contributes in the upward educational and occupational mobility of the children of entrepreneurs.     

Staying with People Who Slap Us Around: Gender,Juggling Responsibilities and Violence in Paid (and Unpaid) Care Work

Little is actually known about women's occupational health, let alone how men and women may experience similar jobs and health risks differently. Drawing on data from a larger study of social service workers, this article examines four areas where gender is pivotal to the new ways of organizing caring labour, including the expansion of unpaid work and the use of personal resources to subsidize agency resources; gender‐neutral violence; gender‐specific violence and the juggling of home and work responsibilities. Collective assumptions and expectations about how men and women should perform care work result in men's partial insulation from the more intense forms of exploitation, stress and violence. This article looks at health risks, not merely as compensable occupational health concerns, but as avoidable products of forms of work organization that draw on notions of the endlessly stretchable capacity of women to provide care work in any context, including a context of violence. Indeed, the logic of women's elastic caring appear crucial to the survival of some agencies and the gender order in these workplaces.     

Ergonomic analysis of workplaces in the iron casting industrial pole in Claudio, Minas Gerais--Brazil

Brazil is currently recognized as the 10th largest producer of castings, and the city of Cláudio, MG is known worldwide as the "Greatest foundry and metallurgical pole in Latin America", with more than 80 companies. However, this large number of enterprises and increasing investments in product development has demanded an increase in manpower and working hours of workers in the sector, proportionally increasing the incidence of occupational related health problems like RSI (repetitive strain injury), WMSDs (work-related musculoskeletal disorders) and industrial accidents. This article aims to characterize the industry from previously conducted case studies to relate the main causes of occupational diseases and outline possible interventions through design, showing how this tool can contribute to improve the working environment, workplace, tools and equipment through ergonomics adjustments.
