An insight into technology diffusion of tractor through Weibull growth model

Most of the technological innovation diffusion follows an S-shaped curve. But, in many practical situations this may not hold true. To this end, Weibull model was proposed to capture the diffusion of new technological innovation, which does not follow any specific pattern. Nonlinear growth models play a very important role in getting an insight into the underlying mechanism. These models are generally ‘mechanistic’ as the parameters have meaningful interpretation. The nonlinear method of estimation of parameters of Weibull model fails to converge. Taking this problem into consideration, we propose the use of a powerful technique of genetic algorithm for parameter estimation. The methodology is also validated by simulation study to check whether parameter estimates are closer to the real value. For illustration purpose, we model the tractor density time-series data of India as a whole and some major states of India. It is seen that fitted Weibull model is able to capture the technology diffusion process in a reasonable manner. Further, comparison is also made with Logistic and Gompertz model; and is found to perform better for the data sets under consideration.     

Reforming Public Administration in Southeast Asia: Trends and Impacts

In Southeast Asia, the recent two decades have witnessed major theoretical, structural, functional, and ethical reforms in the administrative system. In the region, the state-centric mode of public administration that emerged during the colonial and postcolonial periods, has recently been transformed into a businesslike public management in line with the current global movement for such a transition. This article examines the trends of administrative changes in countries such as Brunei, Cambodia, Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. It also briefly evaluates the critical impacts of these recent changes on the systems of public administration the conditions of citizens and societies in the region.     

Microaggressions and Islamophobia: Experiences of Muslims Across the United States and Clinical Implications

This mixed methods exploratory study illustrates the influence of pervasive misconceptions about Islam on the experiences of 314 adult Muslims across the United States. Quantitative results suggest that Muslim stress levels are comparable to the stress levels of other marginalized groups in the United States. Qualitative analysis revealed four themes that highlight the challenges faced by Muslims as well as their resiliency in the face of microaggressions and marginalization. Family therapists may utilize these personal accounts to expand their understanding of Muslim experiences, and to reflect on their own implicit biases toward Muslims in order to reduce chances of premature termination. Clinical implications include using resiliency‐based models and creating collaborative partnerships with community leaders when working with this religious minority group.     

Maximum Likelihood Estimators in Regression Models for Error‐prone Group Testing Data

Since Dorfman's seminal work on the subject, group testing has been widely adopted in epidemiological studies. In Dorfman's context of detecting syphilis, group testing entails pooling blood samples and testing the pools, as opposed to testing individual samples. A negative pool indicates all individuals in the pool free of syphilis antigen, whereas a positive pool suggests one or more individuals carry the antigen. With covariate information collected, researchers have considered regression models that allow one to estimate covariate‐adjusted disease probability. We study maximum likelihood estimators of covariate effects in these regression models when the group testing response is prone to error. We show that, when compared with inference drawn from individual testing data, inference based on group testing data can be more resilient to response misclassification in terms of bias and efficiency. We provide valuable guidance on designing the group composition to alleviate adverse effects of misclassification on statistical inference.     

Formation and negotiation of identity: the case of the Kelantan Kampung Pasir Parit Peranakan Chinese

This article examines the formation and negotiation of identity among the Kampung Pasir Parit Peranakan Chinese, a unique sub-ethnic group of acculturated Chinese in Kelantan. Apart from their original Chinese identity, the Kampung Pasir Parit Peranakan Chinese have also adopted two additional identities, namely Malay and Siamese identities. Intermarriage with Siamese women in the early years is the main reason for the adoption of the Siamese identity, while regular social interactions with the local Malays have led to the adoption of a Malay identity. Thus, the identity of the Kampung Pasir Parit Peranakan Chinese comprises three contrasting components. Given such a complex identity, there is always a need for the Kampung Pasir Parit Peranakan Chinese to negotiate their identities to avoid any identity crisis. This negotiation of identity is at times demonstrated by the co-existence of identities and at times the clear demarcation of identities to fulfil different situational needs.     

Income Dependency on Non-timber Forest Products: An Empirical Evidence of the Indigenous People in Peninsular Malaysia

The indigenous people have been identified to be among the poorest and the most socioeconomically and culturally marginalized people all over the world. The main purpose of the paper is to explore the socioeconomic and demographic factors of indigenous people in Peninsular Malaysia in context of poverty and the role of income dependency of non-timber forest products (NTFP). The data were collected in 2014 and 2015 through primary and secondary sources. Partial least squares (PLS) method was used to analysis the data. PLS is a modeling technique that features multiple regression and principal component analysis. The study shows that still a large number of indigenous households is involved in the NTFP activities. But the communities are moving away from NTFP based income to cash-crop based income because of poor sustainable forest management and lack of forest property rights. However, NTFP have a significant role in the household income and contribute 24% of the average income. Moreover, the analysis shows that location is significant to the poverty. There should be a suitable sustainable forest management system which can teach these indigenous communities about proper way of NTFP gathering and given proper rights to forest land. Furthermore, education is not significant to indigenous people and there is a high rate of school dropout among them. The government should introduce a different education system for indigenous communities which will emphasize the importance of education to them.

孟加拉国人口分布研究

孟加拉国各省、区的人口分布存在着不均衡的特点,采取定量分析的方法,选取人口密度指数、胡佛指数和非均质性指数(index of concentration,Hoover’s index and in-homogeneity index)指标来分析孟加拉国人口分布现有的不平等程度和非均质性。研究结果表明,孟加拉国各省、区的人口集中都存在增加的趋势。同时,通过对斯皮尔曼等级相关系数(Spearman’s rank correlation coefficient)的计算,分析孟加拉国的各地区土地面积和人口密度的关系,发现二者之间存在着较大的负相关关系。     

Framing inter-religious dispute: a comparative analysis of Chinese-, English-, and Malay-language newspapers in Peninsular Malaysia

Religious and ethnicity issues in multicultural societies have always been difficult to report. This study aims to conduct a framing analysis of the coverage of the biggest inter-religious dispute in Malaysia to date – the “Allah” dispute. Specifically, the study compares the coverage of Chinese-, English-, and Malay-language newspapers and assesses the factors that lead to differences in frame building. The findings showed that these newspapers reported the dispute with different degrees of intensity and prominence, and they employed different news sources. Although conflict appeared to be the salient frame used by the dailies, the aspects highlighted by them varied. Sin Chew (Chinese-language daily) was the most vocal in its coverage, which reflected a counter-hegemonic discourse. The Star (English-language daily) used a moderate approach, while Utusan (Malay-language daily) strongly supported the status quo. The frames built by The Star and Utusan could be attributed to the fact that these two newspapers were inclined to serve the politically vested interests of their owners.
