The relationship between heart rate as an indicator of work hardness and results of dynamometry

Heart rate is associated with work hardness and increase linearly with its increasing. In the average of energy consumption, heart rate measurement is simple but non-accurate method for calculation of work hardness. Our purpose in this research was to evaluate the relationship between heart rate and dynamometry results with hypothesis of work hardness effectiveness on the human power. This study was conducted on 102 porcelain workers. Participants were selected randomly. The research tools include stethoscope, the dynamometer. Heart rate, and pinch, grip, and back-leg-chest force were measured and relationships between variables were analyzed with Pearson correlation test and independent T-test using Spss 16 software. The average heart rate of participants were 4.11 ± 1.79 with minimum 60 and maximum 120. The average force of pinch, grip, and back-leg-chest were 8.9 ± 3.20, 4.2 ± 4.5 and 9.36 ± 6.55, respectively. Work hardness for 3.86% of workers were light, 7.12% were moderate and 1% were heavy. Pinch, grip, and back-leg-chest force relation with heart rate were not significant (r=0.01, p=0.85), (r=-0.03, p=0.74), and (r=0.05, p= 0.59), respectively. There was no correlation between heart rate and work hardness. So we can't use the dynamometry results to determine of work hardness.     

Barriers to Remarriage Among Older People: Viewpoints of Widows and Widowers

We conducted this research based on a qualitative approach to describe the opinions of older widows and widowers on remarriage obstacles. Based on purposive sampling and inclusion criteria, we chose 48 participants on maximum diversity of sex, age, education, employment, and socioeconomic status. Two thirds of the participants were female, 40% had spent more than 10 years widowed, and 65% were living with their children. We collected data individually through semistructured, face-to-face interviews. Based on conventional content analyses, 2 independent researchers implemented data analysis manually. Barriers to remarriage were finally categorized into 4 main themes: personal, normative, interactive, and financial factors. Results of this study showed that older people are more concerned about public opinions and social norms surrounding remarriage. As long as these thoughts and norms are not changed, the concept of remarriage among widows and widowers remains a vital taboo and concern.     

Investigating the Effects of Pre‐school Provision: Using Mixed Methods in the EPPE Research

The Effective Provision of Pre‐school Education (EPPE) project is a longitudinal study of young children between the ages of 3 and 7 years. Research began in 1997 and both quantitative and qualitative methods were used to explore the effects of pre‐school education on children’s attainment and social/behavioural development at entry to school, and of any continuing effects on such outcomes at the end of Key Stage 1 (age 7). The sample included over 3,000 children and 141 pre‐school centres drawn from six different types of providers. In addition, a home sample of children who had not attended a pre‐school centre was included. In order to identify the processes that might influence centre effectiveness, observational data were collected and centre managers interviewed. In‐depth case studies of 12 more effective centres were used to explore and illuminate the processes, particularly in relation to pedagogy, associated with better child outcomes. A mixed method approach was adopted to simultaneously answer both confirmatory and exploratory questions, to support user engagement and provide triangulation. The paper argues that the mixed method approach supported the development of stronger research inferences.     

Estimation of finite population mean in simple random sampling and stratified random sampling using two auxiliary variables

In this article, we propose a new class of estimators to estimate the finite population mean by using two auxiliary variables under two different sampling schemes such as simple random sampling and stratified random sampling. The proposed class of estimators gives minimum mean squared error as compared to all other considered estimators. Some real data sets are used to observe the performances of the estimators. We show numerically that the proposed class of estimators performs better as compared to all other competitor estimators.     

Pregnant women’s choice of birthing hospital: A qualitative study on individuals’ preferences

Objective

To investigate pregnant women’s decision making in relation to their choice of birthing hospital and, in particular, their priorities regarding hospital characteristics.

Factors influencing whistle-blowing in the Iranian health system

The purpose of this study is to investigate the factors that contribute whistle-blowing in the Iranian health system and also to develop a model for these factors. Four factors were identified by reviewing the relevant literature including organizational culture factors, organizational factors, materiality of wrongdoing, and individual factors. Because of the local focus of this study, the items of each contributing factor were identified by employing Delphi method. Delphi method was conducted four times and 33 items. Subsequently, the model of factors was designed by DEMATEL technique for the first time in the Iranian context. To test the model, a questionnaire with 52 questions was designed, validated, and distributed among target population. Afterward, the model was tested by applying SEM. The final results indicated that the organizational culture, organizational factors, and materiality of wrongdoing have affected whistle-blowing significantly. However, the effect of individual factor was not significant.     

‘Hunger has brought us into this jungle’: understanding mobility and immobility of Bengali immigrants in the Chittagong Hills of Bangladesh

ABSTRACT

The recent history of the Chittagong Hills in Bangladesh is marked by ongoing conflicts between minority (non-Muslim and non-Bengali) locals and state-sponsored (Bengali Muslim) immigrants. In general, these immigrants are framed as land grabbers who have been receiving protection from a pro-Bengali military force. We propose instead, that the understanding of these Bengalis as a homogenous category of mobile perpetrators fails to take into account their complex histories as mobile landless peasants. Our ethnographic research reveals that the framing of the local minorities and the mobile Bengalis as two antagonistic categories with opposing interests obscures the fact that both categories have fallen victim to very similar regimes of mobilities and immobilities of the state and national and local (political, economic and military) elites. Here, we reject binary thinking that counterpoises mobility and immobility as two antagonistic concepts and argue that mobility and immobility are intrinsically related and their relationship is asymmetrical.
