Prospects for the upskilling of general workers in Britain : a case study comparison of the English and Irish dairy processing industries

While there is strong evidence that longstanding systemic weaknesses in the British economy continue to lead to negative strategic, skills and employment outcomes across much of British industry, there has in recent years been a notable lack of empirical research in the skills and employment relations fields aimed at examining the potential for upskilling or 'employment upgrading' to be achieved for general workers. It is apparent that issues of political economy and in particular the relationship between institutional contexts, competitive performance and skills/employment outcomes at sector level have been largely neglected. This thesis seeks to partly fill this gap by presenting data from a comparative case study of the English and Irish dairy processing industries, the central focus of which was an examination of the consequences for company strategies, employee skills, employment and wage levels of the overriding emphasis on the promotion of competition and efficiency and the lack of a strong industrial policy in the former, and in contrast the existence of a strategic and resource intensive industrial policy in the latter. This research provides an ideal opportunity to address two issues of current theoretical concern, namely the potential for an industrial policy to facilitate upskilling and debates regarding the advantages and disadvantages of different 'varieties of capitalism'. In general terms, the industrial policy context in England was found to inhibit investment in product development and in particular moves by processors in to higher value, advanced market niches, with negative consequences for employee skills and comparatively low wages resulting. However these outcomes were to some extent mitigated by the presence in the UK industry of a number of high-investing foreign multinationals who undertook very substantial new product development, thereby facilitating some notable upskilling for production workers. In Ireland, while significant limitations in both the nature and extent of impact were identified, the 'benign' industrial policy context was found to support processors in moving into advanced product markets, and consequently underpinned the creation of substantial opportunities for upskilling alongside a high standard of living for production operatives. However skills outcomes at workplace level were found to be heavily contingent on a number of different factors, with upskilling not found to be either an automatic or likely consequence of a move up market. In addition, the fact that vocational training in the industry continued to be of a predominantly informal, on-the-job nature was found to create significant tensions and lead to dissatisfaction on the part of production operatives. This research demonstrates the general value of the adoption of a supportive/strategic industrial policy in terms of the potentially positive consequences resulting for strategy, skills and employment outcomes. However it also highlights how the potential of such a policy to facilitate upskilling is limited, being heavily influenced/determined by the structural makeup and key characteristics and trends within particular sectors and product markets. In addition, the need to address broader systemic issues relating to work organisation, the labour process and the nature of vocational training systems is emphasised. More broadly, the findings highlight the problematic nature of the central theoretical conclusion and policy recommendation from the varieties of capitalism literature, that liberal market economies like the UK should accentuate the deregulated/fluid nature of capital, labour and product markets and focus attention on activities/sectors dominated by 'radical' as opposed to 'incremental' innovation; and in contrast arguably demonstrate the need for and potential of the development of thick institutional structures and substantial industry support measures, even in 'traditional' sectors such as dairy

Determination of step rate thresholds corresponding to physical activity intensity classifications in adults

Journal ArticleBackground: Current recommendations call for adults to be physically active at moderate and/or vigorous intensities. Given the popularity of walking and running, the use of step rates may provide a practical and inexpensive means to evaluate ambulatory intensity. Thus, the purpose of this study was to identify step rate thresholds that correspond to various intensity classifications. Methods: Oxygen consumption was measured at rest and during 10 minute treadmill walking and running trials at 6 standardized speeds (54, 80, 107, 134, 161, and 188 m?min-1) in 9 men and 10 women (28.8 ? 6.8 yrs). Two observers counted the participants? steps at each treadmill speed. Linear and nonlinear regression analyses were used to develop prediction equations to ascertain step rate thresholds at various intensities. Results: Nonlinear regression analysis of the metabolic cost versus step rates across all treadmill speeds yielded the highest R2 values for men (R2 = .91) and women (R2 = .79). For men, the nonlinear analysis yielded 94 and 125 step?min-1 for moderate and vigorous intensities, respectively. For women, 99 and 135 step?min-1 corresponded with moderate and vigorous intensities, respectively. Conclusions: Promoting a step rate of 100 step?min-1 may serve as a practical public health recommendation to exercise at moderate intensity

Physical activity differences by birthplace and sex in youth of Mexican Heritage

Journal ArticleBackground: One of the goals of Healthy People 2020 is to increase physical activity (PA) and reduce health disparities among different racial and ethnic segments of the U.S. population. Few studies have been conducted to examine PA differences by birthplace and sex in youth of Mexican heritage. Methods: Participants were 101 youth (43 boys, 58 girls, 59% U.S.-born, 41% Mexico-born) who wore a sealed New Lifestyles NL-1000 pedometer for 7 consecutive days. Results: Mexico-born youth took more steps, on average, than their U.S.-born counterparts (P = .038). However, moderate-to-vigorous intensity (MVI) time did not differ between Mexico- and U.S.-born youth (P = .146). By contrast to birthplace, sex-related differences were more consistent, as boys took more steps (P = .005) and accumulated more MVI time (P = .043) than girls. Only 4% of our sample met either one or both of the PA recommendations. Conclusions: We conclude that PA may differ by birthplace and by sex in youth of Mexican heritage, as U.S.-born girls were the least active segment of our sample. Culturally sensitive interventions to increase daily PA must become a higher public health priority for youth of Mexican heritage, in particular, for U.S.-born girls of Mexican heritage

Children and Pedometers: A Study in Reactivity and Knowledge

International Journal of Exercise Science 6(3) : 230-235, 2013. Pedometers are simple inexpensive tools that are widely used for the measurement of physical activity. Reactivity is always a concern when using pedometers. An issue not yet addressed is the role previous knowledge has on the impact of reactivity. The primary purpose of this study was to examine if reactivity exists in 4th-6th grade students and if prior knowledge about pedometers had an effect on reactivity. Participants included 109 (54 females) 4th- 6th grade students from a suburban charter school. Prior to data collection, students completed a questionnaire to measure their knowledge of pedometers. Pedometers were worn from after-school until before school each day for two weeks with half of the students wearing sealed devices the first week, then switching to unsealed. Steps were counted and pedometers were redistributed each afternoon. Repeated measures ANOVA results showed no significant differences in step counts between unsealed and sealed conditions, or when knowledge and experience regarding pedometers was included as a covariate. Pedometers are inexpensive and reliable tools that researchers and educators can use to measure physical activity. In this study reactivity did not occur with older elementary students and a student’s knowledge of pedometers did not affect reactivity

Factors Influencing Muscular Strength and Endurance in Disadvantaged Children From Low-Income Families

International Journal of Exercise Science 9(3): 306-317, 2016. Examining the correlates of muscular strength and endurance in children from low-income families will provide evidence for interventions to improve these parameters. The purpose of this study was to determine the predictors and trends of muscular strength and endurance in at-risk school-aged children. The sample included 1,232 children (Mean age = 8.8 ± 1.6 years; 625 girls, 607 boys; 60% Hispanic) recruited from three U.S. low-income schools. Children performed health-related fitness testing and wore pedometers for one school week. A stratified random subsample (n = 533) also wore accelerometers to record sedentary behaviors, MVPA, and vigorous physical activity. Generalized linear mixed models were employed to calculate odds ratios (OR) for achieving FITNESSGRAM’s push-up and curl-up standards (met standard = HFZ) from various predictors and to determine odds of achievement across grade levels. A student who achieved the HFZ for VO2 Peak had an OR = 1.66 (p \u3c 0.001) for achieving the HFZ for pushups and an OR = 1.99 (p \u3c 0.01) for achieving the HFZ for curl-ups. Additionally, students whose vigorous physical activity was 1% higher had an OR = 3.25 (p \u3c 0.05) for achieving the HFZ for curl-ups. For cohorts of students separated by one grade level, the OR = 0.48 (p \u3c 0.01) for achieving the HFZ for pushups and OR = 0.71 (p \u3c 0.01) for achieving the HFZ for curl-ups. The results suggest that VO2 Peak, vigorous physical activity, and grade level are significant predictors of muscular strength and endurance in at-risk children

Effect of a 12-Week Summer Break on School Day Physical Activity and Health-Related Fitness in Low-Income Children from CSPAP Schools

Background. The purpose of this study was to examine the effect of a 12-week summer break on school day physical activity and health-related fitness (HRF) in children from schools receiving a Comprehensive School Physical Activity Program (CSPAP). Methods. Participants were school-aged children (; 624 girls and 608 boys; years) recruited from three low-income schools receiving a CSPAP. Physical activity and HRF levels were collected during the end of spring semester 2015 and again during the beginning of fall semester 2015. Physical activity was assessed using the Yamax DigiWalker CW600 pedometer. HRF measures consisted of body mass index (BMI) and the Progressive Aerobic Cardiovascular Endurance Run (PACER). Results. Results from a doubly MANCOVA analysis indicated that pedometer step counts decreased from 4,929 steps in the spring to 4,445 steps in the fall (mean difference = 484 steps; ; Cohen’s d = 0.30) and PACER laps decreased from 31.2 laps in the spring to 25.8 laps in the fall (mean difference = 5.4 laps; ; Cohen’s d = 0.33). Conclusions. Children from schools receiving a CSPAP intervention had lower levels of school day physical activity and cardiorespiratory endurance following a 12-week summer break
