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.     

A co-utility approach to the mesh economy: the crowd-based business model

We explore the mesh economy applications of co-utility, a new concept describing self-enforcing and mutually beneficial interactions among self-interested agents. We show that the crowdsourcing market is naturally co-utile (without additional incentives). Furthermore, we analyze the investment crowdfunding industry and propose solutions that can neutralize the fear and mistrust effects underlying its market in order to make it strictly co-utile. Up on our analysis under the co-utility framework, we corroborate that collaboration is always rationally sustainable, as long as the system is co-utile and that all co-utile outcomes are Pareto-optimal; but not all Pareto-optimal outcomes are co-utile. In addition, reciprocity and hybridity equilibrium are compatible with co-utility in specific cases at which they provide Pareto-optimal outcomes. This methodology of analysis within the framework of co-utility can be extended beyond the crowd-based business models and promises to significantly contribute to economic theory.     

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.     

Conditional Cash Incentive and Use of Health Care Services: New Evidence from a Household Experiment

Studies have recently provided insights into the effects of incentive modalities in the health care sector. However, there is insufficient evidence on the underlying causes of the partial effectiveness of these strategies in the health systems of developing countries. This study presents results from a large-scale randomized experiment across 6848 households in Afghanistan that evaluates the impact of a conditional incentive pay scheme on health facilities. Supported by the target-income hypothesis framework and relaxing the compliance assumption in the empirical modeling, the estimated coefficients yield causal effects of the supply-side conditional incentive on the utilization for health care services. After 2 years, the conditional incentive increased the use of pre-targeted maternal and children health care services among the households at lower levels and at contracted-out health facilities. Additionally, the incentive scheme is associated with sizable efficiency gains at the facility level. These gains are realized at the expense of deterring service users’ satisfaction with physicians’ communication qualities. This study establishes that margins of improvement do exist in the supply-side performance conditioning on an organizational structure and the service contractual arrangements of health facilities. This work provides a framework for the plausible implementation of incentive policies in the health care sector.

     

‘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.
