Development of an instrument for assessing workstyle in checkout cashier work (BAsIK)

Checkout cashier work consists of handling a large number of items during a work shift, which implies repetitive movements of the shoulders, arms and hands/wrists, and a high work rate. The work is associated with a high prevalence of disorders in the neck and upper extremity. The concept of workstyle explains how ergonomic and psychosocial factors interact in the development of work-related upper extremity disorders. The aim of the project was to develop an instrument for the occupational health services to be used in the efforts to prevent upper extremity disorders in checkout cashier work. The instrument is based on the workstyle concept and is intended to be used as a tool to identify high-risk workstyle and needs for interventions, such as training and education. The instrument, BAsIK, consists of four parts; a questionnaire about workstyle, an observation protocol for work technique, a checklist about the design of the checkout and a questionnaire about work organization. The instrument was developed by selecting workstyle items developed for office work and adapting them to checkout cashier work, discussions with researchers and ergonomists, focus-group interviews with cashiers, observations of video recordings of cashiers, and studies of existing guidelines and checklists.     

Effect of ergonomic and workstyle risk factors on work related musculoskeletal disorders among IT professionals in India

'Workstyle' can be described as a mechanism by which ergonomic and psychosocial risk factors interact to affect the development, exacerbation and/or maintenance of upper limb pain and functional limitations. Workstyle is associated with the increase in the work demand. In today's life use of computer in the workplace is very common and it causes to increase the work demand among the workers who are working with computer. As work demand increase, according to the characteristic of workstyle, risk of the development of musculoskeletal disorders also increased. This study aimed at to findout the association between ergonomics risk factors, workstyle and WRMSD. Two hundred IT professionals participated in this study. Result revealed that most prevalenet body regions were lower back (20%), Upper back (16%) and shoulder (14%). Study result says that there is a positive association between workstyle score with musculoskeletal pain (r=0.85). Also it revealed that posture and regional pain is associated (r=0.62), per day use of computer and musculoskeletal pain (r=0.46), micro breaks and pain (r=0.87) and productivity and the pain (r=0.95). This study further validates these observations and extends support for the assessment of working postures and workstyle behaviors during the design of WMSD treatment.     

Participatory ergonomics among female cashiers from a department store

The objective of this paper was to control ergonomic risks among female cashiers working in a department store belonging to the retail market. This study was conducted between May and November 2010. Participatory ergonomics was applied through knowing and understanding how the company works, establishing the work team (Ergo group), training the team in ergonomics-related topics, and making decisions and interventions. The sample was composed of 71 participants--mostly female cashiers--, and all of them have a musculoskeletal compromise, declaring pain or discomfort mainly in the neck, lower back, right wrist and shoulders. Among others, following problems were found: postural overload, repetitive work, manual load handling, mental fatigue, environmental discomfort, variable work schedules, extended working days, and absence of breaks. In the intervention, the main implemented changes were the redesign of workstation, complete change of chairs and keyboards, and the implementation of a rotation system, as well breaks for compensatory exercises. After that, an evident improvement of found problems was observed, therefore it can be concluded that participatory ergonomics is an attractive methodology, appropriate and efficient for solving and controlling ergonomic risks and problems.     

A field experiment comparing mechanical demands of two pruners for flower cutting

Manual flower cutting requires repetitive forceful movements that may explain the high incidence of upper-extremity MSDs among workers of the Colombian flower industry. Force demands may be caused by the use of pruners that have not been designed for Colombian workers. We conducted a repeated measures field experimental study (n=16, 69% women, 20 to 60 years old) to compare the mechanical demands during rose cutting of two different pruners (Traditional vs. alternative pruner) at two different cutting heights (elbow vs. over-shoulder). Demands included the perceived comfort, perceived effort and upper limb's muscular activity and posture. Workers perceived their traditional pruner as more comfortable but requiring more effort than the prototype tool. No benefits were observed regarding ulnar deviation with the alternative pruner. The wrist extension and related muscular activity of the wrist extensors were higher with the prototype pruner. The prototype pruner resulted in reduced muscular load of the wrist flexors; the biceps when working at the elbow height; and the deltoids when working at the shoulder height. However, Moderate results may be explained by the lack of time for workers' adaptation to the alternative tool. New design developments must focus on reducing extension and ulnar deviation of the wrist.     

Le temps de l'activité de la caissière : entre logique productive et logique de service

At first sight, the worktime put in by cashiers at checkout counters seems homogeneous, continuous and repetitive. An empirical study of hypermarket cashiers in France shows, on the contrary, that the time spent working is relatively discontinuous and diversified. It is similar to the time on the job put in by semiskilled workers in industry. What characterizes cashiers' work is their having to manage flows of both products and customers. Their worktime can, therefore, be understood as a compromise that comes out of balancing productivity with human relations, a compromise that sometimes causes conflict. By acquiring an “incorporated know-how”, cashiers manage to fill their assignment.     

Dual-earner couples and the decision to work less: A conceptual model

This paper examines the factors that affect the decision made by dual-earner couples concerning the possibility of one (or both) partners working a reduced-hours schedule. We rely on a comprehensive review of the literature on part-time work among dual-earner couples and on the factors that affect the decisions couples make about their work hours as well as preliminary findings from our ongoing study to consider two key questions: (1) What factors do dual-earner couples take into account when they consider whether one or both might work a reduced-hours schedule? (2) If the couple decides that one partner will work a reduced-hours schedule, how do they decide which partner reduces the hours of employment? Most previous research has focused on the centrality of gender in the decisions that couples make concerning the hours that they work. However, our review of the literature and the preliminary findings of our current research suggest that there are other factors that affect (directly or indirectly) the couples' decisions related to part-time options. Based on this review we present a new decision-making model for two-earner couples that will have implications for future research and policy initiatives. This paper is particularly timely for several reasons: the number of dual-earner couples continues to increase; there is some indication that more employees would choose to reduce their work hours if that were a viable option; and recently, managers and professional workers have become more vocal about their interest in part-time career options.     

Ergonomics in the operating room

Surgical staff is considered to have several ergonomic risk factors, but their physical workload and musculoskeletal health have seldom been evaluated. Clinical examinations of neck and upper extremities were performed in 99 theatre nurses and 93 assisting nurses, all females. Their physical workload was assessed by questionnaire, and by technical measurements of postures, movements and muscular load in subgroups of both categories. The prevalences of diagnoses in neck/shoulders were not remarkably high in the nurses, compared to other occupational groups. In elbows/hands though, the prevalence was rather high among assistant nurses, 13 vs. 5 % in theatre nurses; POR 3.0 (CI 95 % 1.0 - 8.9). Theatre nurses experienced prolonged static postures in the questionnaire, whilst assistant nurses reported high physical load. Accordingly, the technical measurements showed more strenuous working postures in the theatre nurses, but lower wrist angular velocities. The time proportion of muscular rest in m.trapezius was rather high in both groups. Although both groups had some stressful loads they had relatively low prevalence of diagnoses in neck/shoulders. The high proportion of muscular rest may be protective. The elevated risk of elbows/hands diagnoses among assistant nurses may be explained by strenuous work tasks of short duration.     

Seclusion. The nursing challenge.

The research to date shows that there is not much data to guide nursing decisions about the use of seclusion. The justification for its use is not always as clear as one might hope. Although many patients are secluded for violence against themselves or others, there are others who have not been violent who are secluded. There may be justification for secluding violent patients, but, as indicated earlier, it may reinforce the behavior it is designed to stop. There probably is no justification for secluding patients who make loud noises, refuse to take medication, or refuse to participate in activities. In addition, it is disconcerting that a large percentage of patients are secluded for "escalating agitation," that is, they have not acted violently against themselves or others. What is problematic is that staff are undoubtedly predicting violent behaviors in these patients--predictions that might be erroneous. Thus, there is ample room for injustice to occur. The potential for injustice is even greater if certain patients are singled out for seclusion or if patients are secluded longer than they or the staff think that they need to be, as is indicated in some of the studies to date. Moreover, if unit variables are associated with seclusion activity, this too, may be indicative of decision making at certain times of the day or by certain staff members that may not be in the best interest of the patient. What seems fairly clear is that secluding a patient is a distressing event for staff and is viewed extremely negatively by some patients and as a reward by others.(ABSTRACT TRUNCATED AT 250 WORDS)     

Batch sampling to improve power in a community trial. Experience from the Pawtucket Heart Health Program

Experiments involving large social units, such as schools, work sites, or whole cities, are commonly limited in statistical power because the number of randomized units is small, leaving few degrees of freedom for residual (between-unit) error. The authors describe a method for increasing residual degrees of freedom in a community experiment without substantially increasing cost or difficulty. In brief, they propose that the experimental units should be divided into random subsamples (batches). Batch sampling can improve statistical power if the community endpoint means are stable over time or if their temporal variation is comparable in period to the batch-sampling schedule. The authors demonstrate the theoretical advantages of the batch system and illustrate its use with data from the Pawtucket Heart Health Program, in which such a design was implemented.     

Limited Access: Disparities in Flexible Work Schedules and Work-at-home

This research tests predictions regarding potential disparities among the employed by personal characteristics in the ability to vary the starting and ending times of their workday and engage in work from home. Women and African-Americans possess less access to flexible work schedules, even when controlling for most job characteristics. Married men have more access, but only if they are parents, and mothers only if they have pre-school-age children. Workers with part-time or long hours gain far greater access. Work-at-home is more common among women, the married and parents-thus, relatively more reflective of family demands. The results suggest where public and organizational policies could be focused to spread flexible work arrangements more toward those who both most value it and lack it.     

Self-Employment or Government Work? Blacks’ and Whites’ Responses to Long-Term Joblessness during the Great Depression

Investigations of survivalist entrepreneurship often fail to adequately examine displaced workers who suffer exceptionally long unemployment spells. The present study addresses this oversight by analyzing Census data on large northern cities during the Great Depression, exploring how unemployment duration is related to two presumably competing responses to joblessness: self-employment and government relief work. The analysis shows that among persons looking for work two years or more, blacks’ unemployment is positively associated with the odds of self-employment, whereas whites’ unemployment is positively associated with the odds of public emergency work. These findings accord with the theory that when resource-disadvantaged minorities face extraordinary labor market obstacles, they are more likely to become survivalist entrepreneurs than are majority-group members, who have a wider variety of options in the mainstream economy. Yet the results also imply that survivalist entrepreneurship was a viable option for only a small number of displaced black workers.     

The 1999 Small Employer Retirement Survey: building a better mousetrap is not enough

As of 1995, there were 5.3 million small-employer firms (100 or fewer employees) in the United States. These small firms employed 38.0 million individuals, representing 38 percent of all employment. Therefore, low retirement plan coverage among small employers directly affects a sizeable fraction of the national work force. There are a number of reasons why more small employers do not offer retirement plans. Cost and administration-related issues do matter, but for many small employers these take a back seat to other issues. For some, the main driver is the financial reality of running a small business: Their revenue is too uncertain to commit to a plan. For others, the most important reasons for not sponsoring a plan are employee-related, e.g., the workers do not consider retirement savings to be a priority, or the employer's work force has such high turnover that it does not make sense to sponsor a plan. Many nonsponsors are unfamiliar with the different retirement plan types available to them as potential plan sponsors, especially the options created specifically for small employers. For example, most nonsponsors said they have never heard of (36 percent) or are not too familiar with (20 percent) SIMPLE plans for small businesses. Fifteen percent of small employers report that they are very likely to start a plan in the next two years, while 24 percent say this is somewhat likely. Nonsponsors report that the two items most likely to lead to serious consideration of sponsoring a plan are an increase in profits (69 percent) and business tax credits for starting a retirement plan (67 percent). Major drivers of low retirement plan sponsorship among small employers are who they employ and the uncertainty of revenue flows. While issues of administrative cost and burden matter, they are only part of the puzzle. Therefore, the solution is not simply "build it and they will come," by creating simpler and simpler retirement plans geared to small businesses. Rather, it is build it and they will come once the business reaches a certain level of profitability and stability, and once retirement planning and saving are more of a priority for the small employer's workers.     

Ergonomic evaluation of laparoendoscopic single-site surgery ports in a validated laparoscopic training model

Although laparoendoscopic single-site surgery (LESS) is feasible among expert laparoscopic surgeons, it poses many technical challenges not seen in conventional laparoscopy (CL). Recent technological advancements in single-incision instrumentation have created more interest and widespread usage of LESS. However, neither LESS nor its novel instrumentation have been thoroughly studied or evaluated using human factors and ergonomics techniques. Consequently, the aim of this study was to compare the physical performance of LESS to CL using a standardized task. Wrist and elbow angular movements, range of motion and physical discomfort were assessed for 24 novice participants. There were no significant differences for physical comfort/discomfort ratings or elbow and wrist flexion/extension range of motion between CL and LESS. However, wrist radial/ulnar range of motion was significantly greater in LESS compared to CL (p < 0.05). Additionally, wrist radial/ ulnar range of motion was significantly greater using the SILS Port compared to the GelPOINT (p < 0.05). Although further investigation is needed, LESS resulted in greater wrist deviation and range of motion due to the close proximity of the instruments, restrictive nature of the single-port devices, and the need to achieve adequate instrument triangulation and visualization.     

Perceived contra observed physical work load in Swedish dentists

In an earlier questionnaire study, dentists reported high experienced physical work load in their profession, but low to moderate complaints from their musculoskeletal system. The correlation between reported physical work load and pain from the musculoskeletal system was weak. This discrepancy could not be satisfactorily explained. Therefore, a second study was undertaken, in which the same 27 dentists who reported musculoskeletal problems were video recorded during one hour of clinical work, and the records were later analyzed using PEO (Portable Ergonomic Observation). PEO is a frequency analysis method which allows observation of work in real time using a portable computer or video recordings. PEO can be adjusted for registration of single or multiple work operations. Output data are presented as frequency, duration, and sequence of the various work operations. The aim of the present study was to investigate if there was a relation between observed work load recorded with PEO, and subjectively estimated work load and musculoskeletal complaints recorded with a questionnaire based on Visual Analogue Scales. Sitting and standing postures, and head, trunk and arm movements were analyzed. The PEO observations showed that dentists generally perform their clinical work in a sitting position, with the head bent forward almost half of the time. Only weak to moderate correlations (r =0.0-0.6) were found between observed physical work load and subjective estimations of experienced physical work load and musculoskeletal complaints. These findings support the results in our previous study, but they do not explain the large difference between the observed low work load and the subjectively experienced high work load. The study will be followed up by EMG measurements and free interviews, where both muscular load and psychosocial factors will be evaluated.     

Making It In and Making Out: Women in Professional Occupations in Britain and France

The relationship between gender, work and organization in professional occupations can be shown to vary according to different work environments and national contexts. The career patterns of women in chartered accountancy and law in Britain and France are explored in different types of organization in order to determine whether the societal structuring of these occupations is gendered and whether women fare better in small professional practices or large bureaucratic organizations. The findings are derived from a comparative study which combined macro-level data with in-depth qualitative analysis of work and family life histories of a small number of women professionals. While women in the two countries and two occupations were found to share many of the same problems in establishing and pursuing a career, the evidence suggests that women in France may have a marginal advantage over their British counterparts, not so much because they have access to more extensive statutory employment rights but rather because they are more often employed in small practices where they are able to use their independence and their control over working conditions and work-time arrangements to structure their careers according to their own requirements and interests.     

Social work organizations-constructive or destructive

Abstract

Are social work organizations constructive or destructive? What can they, or could they, be? I assume that the conference theme of loss and growth has been addressed in relation to work with children and families. That theme is present in my thoughts, too, some of which I hope to share with you. Social workers work within an organization, whose nature must inevitably affect how they can work with children and families. This is an underlying assumption of this paper, although you may find it elaborated at times. At a very simple level, for example, if the organization is suffering loss - loss of resources, personnel, of value, regard or esteem, loss of security or conviction or direction - any worker will have a different task when working with a child suffering loss than if the organization was secure and optimistic. The inner self would have a different, internalised core to receive projections, distortions or rejection.     

Lay people’s models of the economy: A study based on surveys of consumer sentiments

The purpose of this paper is to use a large data set comprising individual’s responses to survey questions about future economic conditions, unemployment and prices to explore lay people’s models of the economy and specifically their understanding of the relationship between unemployment and economic activity and also between unemployment and prices. The data is taken from the questionnaires used to form monthly indexes of consumer sentiments in Australia. We ask if the implied bivariate relationships are rational in the sense used by Muth (1961) and if they are consistent with the good-begets-good heuristic proposed by Leiser and Aroch (2009). We also ask if they are consistent with the actual operation of economic – and especially monetary – policy in Australia. We find that the data does provide some support for these hypotheses and for recent work in behavioural macroeconomics utilising the good-begets-good heuristic.     

Managerial Hostility and Attitudes Towards Unions: A Canada-US Comparison

We use a cross-country survey of attitudes toward work and unions, which includes a sample of managers in both the US and Canada, to explore whether there is greater attitudinal hostility to unions in the U.S. Our estimates indicate that American manager’s attitudes towards unions are, perhaps surprisingly, less hostile than those of Canadian managers. We explain this first finding by the differential effect of perceived union power, which is greater in Canada than the US and which is correlated negatively with union approval. We also find that US managers are less likely to use extreme methods to oppose union organizing drives, implying that the lower union rates in the US as compared to Canada are not likely the result of greater negativity towards unions themselves but rather some other factor or combination of factors. The implication is that if Canadian managers faced the same labor relations playing field as their US counterparts, they would likely find it easier to thwart union certification drives as well. Alternatively stated, Canadian-style labor relations reforms (such as card-check systems or quicker certification votes) could perhaps tip the balance in favor of unions when organizing in the US.     

A low cost technique to evaluate usable product for small manufacturing companies: a case study on Garcia robot

A usability evaluation technique to evaluate user interfaces is introduces. The technique is effective and affordable for small manufacturing companies. By using this technique, an integration of users' feedbacks and some usability concepts, a product can be 3 times easier to use among potential users and more than 5 times easier to use among motivated users. In addition, the technique can be implemented with the company's employees as participants.
