Mix methods have been executed to conduct the present study. A total of one hundred and twenty-five (125) women who gave birth within the last two years have been selected through purposive sampling. Besides ten (10) case studies and five (5) key informants analysis have been performed in this study. As all the variables;both dependent and independent;used in this study are categorical, the Chi-square test has been used to assess the relationship between social class and obstetric health behavior. In this study, a significant association has been found between taking of iron tablets and occupation of the husband (P = 0.026);taking of iron tablets and educational qualification (P = 0.029);vaccination of mother (TT) and educational qualification (P = 0.004), whereas the association of other variables regarding social class and obstetric health behavior has been found insignificant. So the present study shows that the influence of social class on obstetric health behavior has been significantly reduced. It is evidenced that nowadays the effect of social class on obstetric health behavior has significantly faded by the availability, equality-based health services, and services through satellite clinics in the study area. Stakeholders and concerned authorities should give top priority to the findings while developing strategies to improve the condition of maternal health of Bangladesh to acquire the aims of reducing maternal mortality to less than 70 deaths per 100,000 live births.展开更多

In this study, an innovative latent class based generalized ordered response model (LC-GORM) is formulated and used to assess the effects of various factors on respondents’ choice behavior with respect to congestion charge proposal for Jakarta, Indonesia. The proposed model probabilistically assigns respondents into selfish and altruistic class memberships (latently) based on their knowledge of the proposed scheme and their specific attributes. Aiming to capture observable preference heterogeneity across ordinal choices and allow the thresholds to be varied across observations, we parameterize the thresholds as a linear function of the exogenous variables for each ordinal preference. Using stated preference data collected in Jakarta in December 2013, we incorporate the influence of a comprehensive set of explanatory variables into four categories: charges, latent variables related to respondent’s psychological motivations, mobility attributes and socio-demographic characteristics. Empirical results obviously verify the existence of preference heterogeneity across outcomes. The findings confirm that the altruistic class are more sensitive with respect to acceptance of the scheme, while the selfish class are more sensitive with respect to rejection. The key factors influencing public acceptability include the charge level and respondent variables such as car dependency, awareness of the problem of cars in society, frequency of visits to the city center and frequency of private mode usage.展开更多
