An extension of Franklin's randomized response technique for multi-proportions

ABSTRACT

In this article, we introduce six estimators, three based on row averages and the remaining three on column averages of population proportions for trichotomous population when randomized response sampling with a normal randomizing distribution is used. The estimators have been obtained using the method of moments. All the proposed estimators are shown to be unbiased and their variances have been worked out. The percent relative efficiencies of the column total based estimators with respect to row total based estimators are investigated through empirical study.     

Co‐production in the epidemiological clinic: A decentred analysis of the tensions in community‐based,client‐facing risk work

Public health policies to prevent disease within populations are giving rise to shifting patterns of healthcare delivery in the late modern era. There is an inherent tension in modern medicine between evidence‐based standardisation, on the one hand, and patient‐centred specificity on the other. This tension manifests in recent policy narratives regarding public health risk (which we have characterised in terms of the epidemiological clinic) and co‐production. Drawing on co‐produced data with health trainers (lay health workers tasked with supporting behavioural change in patients at high risk of cardiovascular disease) in a deprived post‐industrial region of England, our decentred analysis focuses on three extended narratives from this data set. Our analysis builds on and develops emerging theories of risk work, informed by Habermas, and we explore the extent to which elite narratives of public health risk are resisted, absorbed, or bracketed off by client‐facing health workers—emphasising the heterogeneity of responses—and locate these responses within the context of the workers' employment conditions, their embodied experiences, and their wider beliefs and traditions. We argue that co‐production—albeit in a highly constrained form—is possible while delivering public health interventions. However, in the context of a community where health is so adversely affected by wider social problems and where task shifting has drawn lower status healthcare workers into these client‐facing roles, workers must find their own ways to negotiate and attempt to reconcile this context with the risk‐framed practices they are required to carry out.     

Physiological stress assessment of female workers at kitchen workstation

This paper explores the extent of the physiological stresses of female workers at kitchen workstation while performing the various activities. For this a survey of eighty homemakers and experiment on sixteen respondents having similar physical and physiological parameters was done. Five activities in which the respondents faced maximum problems were selected and were standardized. Physiological stresses including cardiovascular, muscular, and energy expenditure during these activities were then assessed. Study revealed that fatigue during the selected five activities i.e. cutting, grating, rolling, kneading, dish washing, was felt mainly at the wrist, fore arm, followed by discomfort in the shoulders, upper arm, lower back and neck. Energy expenditure for these activities ranged from 7.0 to10 kJ\min, total cardiac cost of work (TCCW) was between 200.81 to 364.30 beats, physiological cost of work (PCW) was 12.82 to 26.26 beats\min; maximum for grating and minimum for rolling. The percent increase in heart rate was maximum for grating 38.56 and minimum for rolling 16.20. Reduction in grip and pinch strength of right hand was found more as compared to the left hand.
