The purpose of this study was to describe the pattern of change in effort sense and the value of this pattern in predicting work end-point at relatively high work intensity (80% V̇O2 max). The patterns of change of various physiological functions were also observed. Two modes of work (walking and running) were compared to ascertain generalizability of results. 26 healthy male volunteers served as subjects. Time to exhaustion (ET) did not differ between walking and running. As work continued during both tasks, significant increases of V̇E, V̇E/V̇O2, V̇E/V̇CO2 and HR and a significant decrease of ET were observed; while V̇O2 and R remained fairly constant. V̇O2 and V̇E during the run were about 5% greater than during the walk; there were no differences in other measures. Ratings of perceived exertion (RPE) from the Borg Scale were identical for both conditions, increasing in a near linear fashion from a value of 12.9 at 25% of total work time to 18.9 at exhaustion. Ratings obtained at 25 and 50% ET were extrapolated to time of exhaustion; the point of intercept corresponded to ratings of perceived exertion for maximal work. At exhaustion, subjects rated perception of respiratory exertion for the walk as less than that for the run; perception of leg exertion was not different for the two conditions. Plasma lactate, epinephrine and norepinephrine concentrations following exercise did not differ between the two conditions. The findings for the walking experiment were essentially replicated in a second investigation involving another 28 subjects. It is concluded that, with the exception of V̇O2 and some ventilatory parameters, walking and running ar the same relative work intensity resulted in comparable perceptual and physiological responses. Psychophysical judgments made early during work were reasonably accurate predictors of exhaustion time.

In recent years, scholars have begun to document the emergence of private migrant schools in urban China. However, neither education nor labor scholars have empirically investigated teachers’ work. Because it is precisely those with the fewest economic resources that have been restricted to privatized education in the city, migrant schools are dependent on a highly exploitative form of employment. Based on a study of Guangzhou and Beijing, we see that there is diversity in working conditions. In Beijing, teachers are subject to extralegal precarity in which basic legal enforcement is tenuous to nonexistent. In Guangzhou, there is greater legal compliance, but management has employed market discipline to shift risk onto teachers. In general, teachers’ work in migrant schools is similar to other forms of migrant labor in China, characterized by low pay, long hours, high work intensity, and lack of job security. The article concludes by assessing the divergent politics of migration in each city while considering the implications for socioeconomic inequality.

Interventional doctors are exposed to radiation hazards during the operation and endure high work intensity. Remote vascular interventional surgery robotics is a hot research field that can not only protect the health of interventional doctors, but also improve accuracy and efficiency of surgeries. However, the current vascular interventional robots still have many shortcomings to be improved. This article introduces the mechanical structure characteristics of various fields of vascular interventional therapy surgical robots, discusses the current key features of vascular interventional surgical robotics in force sensing, haptic feedback, and control methods, summarizes current frontiers about autonomous surgery, long geographic distances remote surgery and MRI-compatible structures. Finally, combined with the current research status of vascular interventional surgery robots, this article analyzes the development directions and puts forward a vision for the future vascular interventional surgery robots.

The following article discusses the problem of organizing and monitoring the special-physical and technical training of young gymnasts at the stage of sports improvement. It is shown that the main advantage achieved during the training session with objects is the regulation of the number of repetitions at high work intensity.

Purpose – The purpose of this paper is to identify whether there are particular employee groups that are more vulnerable to work intensification and its outcomes for well-being. Design/methodology/approach – This paper utilises data collected in two representative national surveys in 2005 (n=1,004) and 2009 (n=1,016), first to determine which employee groups are most vulnerable to work intensification and, second, to identify who is more vulnerable to the impacts of high work intensity on well-being, in terms of job (dis)satisfaction, stress, fatigue, and work-life imbalance. Findings – Professionals reported significantly higher levels of work intensity than all other occupational groups, and higher levels of stress and work-life imbalance. In addition, full-time employees experienced greater work intensity than part-timers, and union members than non-union members. Public-sector employees reported greater stress and work-life imbalance than those in the private sector. There was also a small, but significant and consistent, interaction effect that identified women as more negatively impacted by high work intensity than men. Research limitations/implications – Professionals have become vulnerable workers, in the sense of high levels of work demand, and the notion of worker vulnerability needs to recognise this. Future research on vulnerable employees would benefit from a broader conception of what constitutes vulnerability, exploring a wider range of employee groups who might be considered vulnerable, and including a wider range of potential outcomes for the lives and well-being of the individuals concerned. In particular, a more finely grained examination of the working conditions of professionals would be desirable, as would a more detailed examination of the reasons for the higher negative impact of work intensity on women. Practical implications – One way of improving the sustainability of professional working is to foster higher rates of part-time working, which brings better outcomes in terms of stress and work-life balance. This, however, is hardly a societal remedy and the question of how to reverse deteriorating job quality among professionals, particularly those struggling to balance work and family demands, is something that needs much greater attention. Originality/value – The paper expands the notion of “vulnerable workers” to recognise those groups most at risk of work intensification, and the outcomes of that intensification for satisfaction, stress, fatigue, and work-life balance. The authors add to the small group of studies highlighting the degradation of professional work, as well as identifying other types of employee who are more vulnerable to work intensification. The use of two large-scale surveys, with a four-year gap, has allowed a high degree of consistency in the patterns of vulnerability to be revealed.
