How does a backrest work?

After discussing the distribution of forces in the stable upright posture and illustrating the importance of the lumbar lordosis for minimising muscular effort in this position, the loadings on the spine and muscles of the back are outlined during upright sitting. It is shown that the backrest locates the lumbar spine so that the CG of the superincumbent body parts can be positioned above the vertebrae, permitting the gravity load to be transmitted to the seat without the counteracting torques which muscles would have to provide if this position was not adopted. The forces arising from other sitting positions are then discussed, and some conclusions drawn for seat design.     

Teachers’ personal web use at work

This article presents findings from an online survey of teachers concerning personal web use (PWU) at work. Often considered as ‘cyberslacking’ or ‘Internet abuse’, PWU is a growing phenomenon within increasingly Internet-dependent workplaces. The findings of this study highlight a wide range of types of personal web usage amongst teachers ranging from sending personal emails to social networking and personal banking as well as a range of reasons for PWU from a means of addressing permeable work-life boundaries and coping with work intensification to providing a virtual space for routine resistance. The data also suggest that, rather than being detrimental to the organisation, PWU could potentially be a means of increasing worker productivity and developing the digital literacy of teachers. It concludes by considering the implications of the findings for senior managers within organisations.     

What does computer support for cooperative work mean? a structurational analysis of computer supported cooperative work

Technical developments in electronic communication and computing coupled with new understanding of relationships between computers and work processes has given impetus to a significant amount of research in the area of Computer Supported Cooperative Work (CSCW). Much of this work, however, lacks strong theoretical foundations, and there is no clear definition of CSCW, the major research questions of the field, or appropriate strategies for research. In this paper we suggest Giddens' theory of structuration as a conceptual foundation for CSCW research and propose a formal definition for CSCW. We conclude by discussing seven implications of the framework for future research into: (a) platform software features, (b) research methods, (c) systems development approaches, (d) features of CSCW development methodologies, (e) interactions between CSCW use processes and organizational structures, (f) interactions between work processes and CSCW applications, and (g) larger social change due to adoption of CSCW applications.     

The work compatibility improvement framework: an assessment of the worker–work environment interaction in the manufacturing sector

The manufacturing sector in the US is challenged by high health care costs and shortage of qualified workers, which are largely attributed to the degree of fit between the worker and work environment. In this regard, a healthy worker–work environment interface is a necessary and sufficient condition for the containment of health care costs and the retaining/attraction of highly qualified knowledge workers and should be based on the principles of optimum physical, cognitive and emotional health for the workers. In prior research, the Work Compatibility Improvement Framework (WCIF) was introduced as a vehicle to address these issues and was defined as the identification, improvement and maintenance of the well-being characteristics of the workforce and its interaction with the work environment through the application of engineering, medicine, management and human sciences methodologies, technologies and best practices. This paper advances WCIF by examining its applications in manufacturing with regard to the evaluation of working conditions impacting musculoskeletal/stress outcome measures. A study was conducted in a machining department of a bag packaging manufacturer in the Midwest of the United States. The work tasks were planned and executed with regard to the following aims: (1) to compute work compatibility as a function of work demands and energisers; (2) to establish whether the prevalence of musculoskeletal/stress disorders increases with a decrease in the quality of worker–work environment interface in terms of work compatibility level and other work factors such as shift and job category. A major finding is that a ‘poor’ work environment (a function of all work domains) results in musculoskeletal/stress disorders that are 105% and 67% higher than those for a ‘good’ work environment. The evening shift exhibited the poorest compatibility followed by the night shift relative to the day shift. Application of the work compatibility approach demonstrated the detection of non-added value work. It is essential to evaluate the various domains of worker–work environment interface to uncover the root causes that tend to sub-optimise the physical/cognitive/emotional health of the workforce. The WCIF was used to uncover the non-value added effort in the work process. These findings will have major implications for developing and implementing customised design interventions with the aim to maximise the benefit and reduce the cost of employees in a manufacturing enterprise. The study findings suggest that the WCIF should be pursued as a potential strategic tool for optimising human performance in an enterprise to create healthy workplaces.     

Do work technique and musculoskeletal symptoms differ between men and women performing the same type of work tasks?

Musculoskeletal disorders are more common among women than among men. When comparing the difference between men and women in the prevalence of musculoskeletal disorders, methodological problems arise as men and women seldom perform the same type of activities, neither at work nor at home.

The main objective of this cross-sectional case study was to compare work technique and self-reported musculoskeletal symptoms between men and women performing the same type of work tasks within a metal industry. Other factors, such as leisure activities, were also taken into consideration. Three data collection methods were used; questionnaire, interviews and systematic observations. The results from the observations revealed that women worked more frequently and during longer times with their hands above shoulder height than men. Working with hands above shoulder height is considered a risk factor for neck and shoulder disorders according to previous studies. Workplace design factors were probably a reason for differences in working technique between men and women. A higher proportion of women than men reported shoulder symptoms. Women spent more time on household activities than men, which indicates a higher total workload in paid and unpaid work.     

Interactive or interruptive? Instant messaging at work

The use of instant messaging (IM) technology at work is controversial, due to the interruptions it may cause and the difficulties associated with quantifying its benefits for individuals, teams and organizations. In this study, we investigate the use and impact of IM tools in the workplace. Based on theories of communication performance and social networks, we propose that while the use of IM will cause work interruption, it will also lead to improved communication quality and the establishment of trust between colleagues. These mediating variables will in turn influence group outcomes. We validate our research model with data collected through a survey of 253 working professionals. The data suggests IM can significantly contribute to communication performance in the workplace, where the benefits overwhelm the negative effects associated with work interruption. The theoretical and practical contribution and implications of the research are discussed.     

High-demand jobs: age-related diversity in work ability?

High-demand jobs include 'specific' job demands that are not preventable with state of the art ergonomics knowledge and may overburden the bodily capacities, safety or health of workers. An interesting question is whether the age of the worker is an important factor in explanations of diversity in work ability in the context of high-demand jobs. In this paper, the work ability of ageing workers is addressed according to aspects of diversity in specific job demands and the research methods that are needed to shed light upon the relevant associated questions. From the international literature, a body of evidence was elicited concerning rates of chronological ageing in distinct bodily systems and functions. Intra-age-cohort differences in capacities and work ability, however, require (not yet existing) valid estimates of functional age or biological age indices for the specific populations of workers in high-demand jobs. Many studies have drawn on the highly demanding work of fire-fighters, ambulance workers, police officers, medical specialists, pilots/astronauts and submarine officers. Specific job demands in these jobs can be physical, mental or psychosocial in origin but may cause combined task-level loadings. Therefore, the assessment of single demands probably will not reveal enough relevant information about work ability in high-demand jobs and there will be a call for more integrated measures. Existing studies have used a variety of methodologies to address parts of the issue: task analyses for quantifying physical work demands, observations of psychological and physiological parameters, measures of psychosocial work demands and health complaints. Specific details about the work ability of ageing workers in high-demand jobs are scarce. In general, specific demands are more likely to overtax the capacities of older workers than those of younger workers in high-demand jobs, implying greater repercussions for health, although these effects also vary considerably within age cohorts. Functional tests for job-specific work ability should be developed for high-demand jobs in order to monitor individual functional ageing and to facilitate well-timed intervention. It is concluded that a shift from 'no-diversity thinking' to 'diversity thinking' is needed in the context of deciding about the work ability of ageing workers in high-demand jobs.     

Good vibrations: do electrical therapeutic massagers work?

Health, leisure and beauty activities are increasing in popularity, with a particular emphasis on self-help and alternative health practices. One product type that has increased sales with this expansion is the hand-held electric massager. These are products that use vibration as a means of alleviating muscular strains and pains, as well as promoting relaxation. Paradoxically, these products are extremely popular as gifts, but are soon discarded. A multi-disciplinary research team was commissioned by a British manufacturer of electrical consumer products to investigate user attitudes and perceptions of existing massagers, to identify areas of user dissatisfaction. The manufacturer was also concerned about a possible stigma attached to these products because of an association with sex aids. This paper provides an account of the perceptions of both consumers and therapists regarding the use of these products. Identifying the differences between the perceptions of consumers and therapists should help provide a basis for effective integration of user needs, manufacturer requirements, designers' skills and sound therapeutic practice. The results provide insight to support the development of more effective hand-held massagers.     

Does musculoskeletal discomfort at work predict future musculoskeletal pain?

The objective of this prospective cohort study was to evaluate if peak or cumulative musculoskeletal discomfort may predict future low-back, neck or shoulder pain among symptom-free workers. At baseline, discomfort per body region was rated on a 10-point scale six times during a working day. Questionnaires on pain were sent out three times during follow-up. Peak discomfort was defined as a discomfort level of 2 at least once during a day; cumulative discomfort was defined as the sum of discomfort during the day. Reference workers reported a rating of zero at each measurement. Peak discomfort was a predictor of low-back pain (relative risk (RR) 1.79), neck pain (RR 2.56), right or left shoulder pain (RR 1.91 and 1.90). Cumulative discomfort predicted neck pain (RR 2.35), right or left shoulder pain (RR 2.45 and 1.64). These results suggest that both peak and cumulative discomfort could predict future musculoskeletal pain.     

How does background music tempo work for online shopping?

This research examines the impact of background music tempo, an emotional stimulus, on consumer attitude in online shopping. The authors conducted two empirical studies based on the same experimental design. The results of both studies supported the study’s main hypothesis: background music tempo positively affects consumer arousal. It also suggests that product category moderates the influence of arousal on pleasure such that a positive effect occurs when shopping online for hedonic products but not for utilitarian products. In addition, consumer trust mediates the positive influence of pleasure on purchase intention. The authors also discuss the managerial implications of the empirical results.     

How do we fit underground coal mining work boots?

Abstract

Acceptable footwear fit, particularly width, is subjective and vaguely quantified. Proper shoe fit is important because it affects both comfort and the potential to prevent injury. Although mismatches between the feet of underground coal miners and their internal boot dimensions are known, no research has been undertaken to determine the impact of these mismatches on worker perceptions of fit, comfort and pain. This study aimed to quantitatively assess mining work boot fit relative to underground coal miners’ subjectively rated work boot fit and comfort, reported foot problems, lower limb pain and lower back pain in order to develop evidence-based work boot fit recommendations. Traditional footwear fitting methods based predominantly on foot length are insufficient for underground coal mining-specific footwear. Instead, fit at the heel, instep and forefoot must be considered when fitting underground coal mining work boots, in conjunction with the traditional length measurement.Practitioner summary: Underground coal miners report their work boots fit but are uncomfortable. This study assessed actual fit relative to perceived fit, comfort, foot problems, lower limb pain and lower back pain of 197 miners. Fit at the heel, instep and forefoot must be considered when fitting mining work boots.     

The impact of the nature of globally distributed work arrangement on work–life conflict and valence: the Indian GSD professionals’ perspective

While there is a rich literature exploring the various facets of Globally Distributed Systems Development (GSD), there is scant attention given to the human resource issues such as work–life conflict (WLC) faced by GSD professionals and their valence toward globally distributed work. In this study, we attempt to identify factors that influence offshore GSD workers’ WLC and their valence toward globally distributed work. Specifically, we focus on factors related to the nature of the distributed work arrangements as experienced by offshore Indian workers involved in GSD. On the basis of survey data, we find support for the impact of a number of distribution-related variables on WLC and valence.     

Investigation into the performance of strenuous work at high environmental temperatures—The relationship between heart rate and a fixed work/rest ratio

Employees in industry may be required to work in hot conditions which can result in heat strain. If work is to continue in potentially dangerous conditions, recommendations are needed to ensure that adequate precautions are taken. A requirement for the implementation of these recommendations is a simple means of assessing the suitability of work/ rest periods. This paper describes the first part of a study to develop simple predictive methods, related to the World Health Organization limit of a heart rate during an average work/rest cycle, of 110 beats min⁻¹.Subjects were six acclimatised, fit males. Skin temperature, rectal temperature and heart rate were monitored. They performed block-stepping at a metabolic rate of 450 W at 27, 28, 29, 30 and 31°C wet-bulb globe temperature. Humidity was low. Exposures were for five hours on each day, on a 45/15 minute work/rest schedule. Heart rates were measured and heart-rate indices calculated. Correlation between the indices and the resting heart rate were determined. The highest correlation ($\text{r = 0.747, p < 0.001}$) was found between resting rate and the “5th hour cycle rate” (the average work/rest cycle heart rate during the fifth hour). Results indicate that the resting heart rate (measured on a seated individual after 10 min exposure to the conditions under investigation), has predictive value for calculating “cycle rate”.     

Cyberloafing at the workplace: gain or drain on work?

This study examined the impact of cyberloafing on employees' emotion and work. We also examined gender differences in employees' perception towards cyberloafing. In general, respondents felt that some form of cyberloafing at work was acceptable. Men were also more likely to report that cyberloafing has a positive impact on work compared to women. As well, our findings suggest that browsing activities have a positive impact on employees' emotion while emailing activities have a negative impact. Results of our study provide useful insights for researchers and managers in understanding employees' attitudes towards cyberloafing, and how cyberloafing can result in gain or drain in employees' work productivity.     

What can possibly go wrong? Anticipatory work in space operations

This paper explores how different forms of anticipatory work contribute to reliability in high-risk space operations. It is based on ethnographic field work, participant observation and interviews supplemented with video recordings from a control room responsible for operating a microgravity greenhouse at the International Space Station (ISS). Drawing on examples from different stages of a biological experiment on the ISS, we demonstrate how engineers, researchers and technicians work to anticipate and proactively mitigate possible problems. Space research is expensive and risky. The experiments are planned over the course of many years by a globally distributed network of organizations. Owing to the inaccessibility of the ISS, every trivial detail that could possibly cause a problem is subject to scrutiny. We discuss what we label anticipatory work: practices constituted of an entanglement of cognitive, social and technical elements involved in anticipating and proactively mitigating everything that might go wrong. We show how the nature of anticipatory work changes between planning and the operational phases of an experiment. In the planning phase, operators inscribe their anticipation into technology and procedures. In the operational phase, we show how troubleshooting involves the ability to look ahead in the evolving temporal trajectory of the ISS operations and to juggle pre-planned fixes along these trajectories. A key objective of this paper is to illustrate how anticipation is shared between humans and different forms of technology. Moreover, it illustrates the importance of including considerations of temporality in safety and reliability research.     

A US Client’s learning from outsourcing IT work offshore

Based on 45 interviews and significant documentation, we explore the offshore outsourcing experiences of a US-based biotechnology company. This company offshore outsourced 21 IT projects to six suppliers in India. Senior managers and the official documents from the Program Management Office consistently reported that offshore outsourcing was successful in reducing the company’s IT costs. But interviews with knowledgeable participants actually managing the projects suggest that many projects were not successful in meeting cost, quality, and productivity objectives. We found evidence that this company’s offshore strategy to simply replace domestic contractors with cheaper, offshore suppliers was a poor fit with its social and cultural contexts. Specifically, we found that strong social networks between the company’s internal IT employees and domestic contractors were not easily replicated with offshore suppliers. Furthermore, the internal project management processes were often incompatible with offshore suppliers’ processes. This paper also analyzes seven project characteristics that differentiate highly-rated projects from poorly-rated projects. These project characteristics are type of IT work, size of supplier firm, location of supplier employees (onsite/offshore), dollar value of the contract, duration of the project, timing of the project, and client unit managing the project. The paper concludes with four overall insights for clients and suppliers.

Automatic work objects calibration via a global–local camera system

In a human–robot collaborative manufacturing application where a work object can be placed in an arbitrary position, there is a need to calibrate the actual position of the work object. This paper presents an approach for automatic work-object calibration in flexible robotic systems. The approach consists of two modules: a global positioning module based on fixed cameras mounted around robotic workspace, and a local positioning module based on the camera mounted on the robot arm. The aim of the global positioning is to detect the work object in the working area and roughly estimate its position, whereas the local positioning is to define an object frame according to the 3D position and orientation of the work object with higher accuracy. For object detection and localization, coded visual markers are utilized. For each object, several markers are used to increase the robustness and accuracy of the localization and calibration procedure. This approach can be used in robotic welding or assembly applications.     

Exploring ‘Generation Y’ interaction qualities at home and at work

Information technology support of office work has increased rapidly in functionality, but new ways of interacting have evolved more slowly. This paper adds to the design research community’s notion of interaction quality by exploring these new ways of interacting and comparing them in the home and work contexts. We describe and analyze two interview studies conducted with office workers to consider how they perceive, experience and compare interaction qualities. Six interaction qualities (instant, expressive, playful, collaborative, responsive and flexible) were identified that together embody an interaction style that we have labeled ‘Generation Y.’ From learning and comparing these qualities, we found that personal and natural type of interactions were mostly experienced in the more private home context. Formal and subtle type of interactions were mostly experienced in the more public work context. We also found that the office workers scored the interaction qualities in their home context as richer than in their work context. This study resulted in a set of design guidelines, aiming to be used to implement the Generation Y interaction style in future office tools and applications. Designers and researchers will benefit from the result of this study from understanding rich interaction design in the work context.
