Gendered Meanings of Commitment from High Technology Engineering Managers in the United Kingdom and Sweden

This article considers why women managers are often perceived to be ‘less committed’ at work than men, through an exploration of male and female managers' meanings of ‘commitment’, to see whether their meanings are shared. Despite a large body of literature on the concept of commitment, managers' own meanings of commitment have not been reported. In general, engineers reported that they used the term ‘committed’ without defining what it meant. Their meanings were a broad composite of organizational and career commitment, focused on very strong affective commitment with almost no emphasis on continuance commitment, in contrast to the traditional (1979) definitions of commitment (Mowday et al. 1979). Results from this interview study of engineering managers and senior technologists (20 males, 17 females, 17 British, and 20 Swedish graduate engineers, from vice‐president to senior technologist) show that there are differences in male and female engineers' unprompted meanings of commitment at work, as well as differences in meaning between the three levels of management sampled. Females responded more often with less visible ‘commitment’ meanings such as involvement, being people‐concerned, and availability. More males (and top managers) used the term commitment to mean task delivery, being proactive, being innovative, adding value, and being ready for challenge. The gender differences identified in reported meanings could impact on the assessment of women's commitment, when evaluated for promotion, career development and professional chartered status by the mostly male engineering managers.     

Assessment of energy balance of Indian farm women in relation to their nutritional profile in lean and peak agricultural seasons

In India, the farm women are not only involved in household activities but also contribute in various farm operations, animal husbandry. The objective was to assess nutritional profile of the farmwomen and their occupational health problems, to compare the physiological workload in lean and peak seasons and to find out relationship between physiological workload and nutritional intake. The study was conducted on a sample of 90 farmwomen. Energy Intake was calculated using physiological fuel values of carbohydrate, fat and protein. Energy Expenditure Rate (EER), Total Energy Expenditure (TEE) and Energy Balance were calculated. The physiological workload was assessed using sub-maximal workload technique. The results revealed that all the respondents of all categories were, more or less, performing all the agriculture, allied and household activities. In all the agriculture activities physiological hazards such as body pain and fatigue were dominant. Dietary, nutritional and energy intake was lower for heavy workers, from all landholding and BMI categories. HR and OCR were in linear relationship in all BMI categories. Physical work capacity increased with good nutritional status and decreased with age. Regression equations were suggested for calculating oxygen consumption (y) at their known heart rate (x) during various agriculture operations.     

An ergonomic approach to design hand tool for agricultural production

Hand tool mechanisms designed to reduce the risk factors have rarely been studied. In this paper it is analyze trowel firstly designing in CATIA and then its Finite Element Analysis has been carried out by ABAQUS. The main emphasis is on finding stresses by using this software, then removing them by suitable mechanical working on tool & ergonomic change in the design of handle to make it more comfortable. Body part discomfort score and overall discomfort rating experienced by the subjects had also been estimated. During the muscular activity workers physiological responses i.e. energy expenditure rate, oxygen consumption rate and heart rate increases. This increase in physiological responses is related to the type, intensity and duration of work and thus sets limits to the performance of heavy work. In this paper oxygen consumption rate and heart rate was used for physiological cost estimation. These parameters were measured by Computerized Ambulatory Metabolic Measurement System K4b2.     

Shift work--problems and its impact on female nurses in Udaipur, Rajasthan India

Abstract : There is good evidence that shift work has negative effects on workers health, safety and performance. It is quite appropriate that attention is paid to this very important feature of socio-technical systems, which may adversely affect mental and physical health, social life and safety of shift workers. Research into the impact of shift work on professionals has consistently identified a range of negative outcomes in physical, psychological, and social domains (Akerstedt, 1988; Costa, Lievore, Casaletti, Gaffuri, & Folkard, 1989; Kogi, 2005; Paley & Tepas, 1994). Hospitals, the biggest employer in the health care field, employ more night shift workers than any other industry. It can therefore be inferred that in medical domain high percentage of workforce may be affected by problems related to shift work. Thus the present study will provide knowledge base for the problems faced by the female nurses. The present study was undertaken with an objective of getting an insight into the problems faced by female nurses in shift work. . It was found that the female nurses in India worked on roaster pattern of change in shift every seven days. They did not have a say in the change of duties, it could only be done on mutual grounds. Partners of younger group did not much adjust to their shift pattern this created stress among the nurses.The results showed that the female nurses in both the age groups i.e. 30-45 years and 45-60 years faced many problems related to health and well being, fatigue, social and domestic situations. They could not give much time to their children in particular. Travelling in nights was risky for them. Common problem was the insufficient sleep during night shifts. The nurses had to cater to the needs of the family, children in particular along with the adjustments to be made due to shift work. They had to sometimes do the night duties and attend social functions as a part of their duty. Children and husband in some cases did not cooperate this lead to frustration. When asked as to whether they would could shift job if they get regular one more than 50 % said yes this means that there need to be come training and intervention for the shift workers and their family so that the problems faced and their impact on personal health of the female nurses could be reduced.     

Stein rule prediction of the composite target function in a general linear regression model

This paper considers the problem of simultaneous prediction of the actual and average values of the dependent variable in a general linear regression model. Utilizing the philosophy of Stein rule procedure, a family of improved predictors for a linear function of the actual and expected value of the dependent variable for the forecast period has been proposed. An unbiased estimator for the mean squared error (MSE) matrix of the proposed family of predictors has been obtained and dominance of the family of Stein rule predictors over the best linear unbiased predictor (BLUP) has been established under a quadratic loss function.     

Discrete Burr and discrete Pareto distributions

In this paper we obtain discrete Burr and Pareto distributions using the general approach of discretizing a continuous distribution and propose them as suitable lifetime models. It may be worth exploring the possibility of developing discrete versions of the Burr and Pareto distributions, so that, the same can be used for modeling discrete data. The equivalence of continuous and discrete Burr distributions has been established. Some important distributional properties and estimation of reliability characteristics are discussed. An application in reliability estimation in series system and a real data example on dentistry using this distribution is also discussed.     

Comparing several exponential populations with more than one control

Suppose there are k ₁ (k ₁ ≥ 1) test treatments that we wish to compare with k ₂ (k ₂ ≥ 1) control treatments. Assume that the observations from the ith test treatment and the jth control treatment follow a two-parameter exponential distribution and , where θ is a common scale parameter and and are the location parameters of the ith test and the jth control treatment, respectively, i = 1, . . . ,k ₁; j = 1, . . . ,k ₂. In this paper, simultaneous one-sided and two-sided confidence intervals are proposed for all k ₁ k ₂ differences between the test treatment location and control treatment location parameters, namely , and the required critical points are provided. Discussions of multiple comparisons of all test treatments with the best control treatment and an optimal sample size allocation are given. Finally, it is shown that the critical points obtained can be used to construct simultaneous confidence intervals for Pareto distribution location parameters.     

Utilization of higher order moments of scrambling variables in randomized response sampling

In this paper, a new estimator for estimating the proportion of a potentially sensitive attribute in survey sampling has been introduced. The proposed estimator makes use of higher order moments of the scrambling variable at the estimation stage. The proposed estimator has been found to be more efficient than the estimator due to Kuk [1990. Asking sensitive questions indirectly. Biomerika 77(2), 436–438] and Franklin [1989. A comparison of estimators for randomized response sampling with continuous distributions from a dichotomous population. Comm. Statist. Theory Methods 18, 489–505] type estimators in randomized response sampling. Recently, Guerriero and Sandri [2007. A note on the comparison of some randomized response procedures. J. Statist. Plann. Inference 137, 2184–2190] have shown that the family of randomized response models proposed by Kuk [1990. Asking sensitive questions indirectly. Biomerika 77(2), 436–438] is better than the Simmons’ family in terms of efficiency and protection.     

Money management and control in the Indian joint family across generations

Studies of money management and control will have more cross‐cultural relevance if the family context of money across generations is taken into account. The study of money management and control in middle‐income nuclear and joint family households in urban India illustrates the importance of examining money flows within the wider family context because there is a two‐way flow of money beyond the married couple – between parents and adult children, siblings and other members of the extended family. In the three or four generational joint family, control and management at the household level is not necessarily duplicated for the constituent couples. We draw on open‐ended interviews of 40 persons from 27 urban middle‐income households in North India, between November 2007 and January 2008, to show that the male control of money is the dominant pattern. This pattern is linked to the ideology of male dominance that is found among the middle, lower middle and struggling households, particularly in non‐metropolitan households. The upper‐middle‐class households predominantly in metropolitan households show a pattern of joint or independent control. The focus is on the couple's money decisions within the context of the wider family.
