Subethnic interpersonal dynamic in diasporic community: a study on Chinese immigrants in Vancouver

ABSTRACT

Ethnicity is a social construct that can be conceptualised as a social classification delineating certain boundaries between an ethnic group and the dominant group. Members of an ethnic group are assumed to share similar cultural characteristics and to be homogenous among themselves. Many studies in ethnic organisations have indicated that subethnicity also exists within an ethnic group, but research on subethnicity is scant. Based on the findings of an exploratory study conducted in Vancouver, Canada, we examined how, at an interpersonal level, place of origin, language, mutual bias and discrimination and transnational politics divide the Chinese diasporic community subethnically. Meanwhile, being Chinese in the Canadian context and willingness to break the subethnic boundaries are noted as counterforces to the subethnic divide. We contend that interpersonal interaction is an imperative dimension for the understanding of the shaping of boundary between different subethnic groups.     

Profile likelihood approaches for semiparametric copula and frailty models for clustered survival data

ABSTRACT

In clustered survival data, the dependence among individual survival times within a cluster has usually been described using copula models and frailty models. In this paper we propose a profile likelihood approach for semiparametric copula models with different cluster sizes. We also propose a likelihood ratio method based on profile likelihood for testing the absence of association parameter (i.e. test of independence) under the copula models, leading to the boundary problem of the parameter space. For this purpose, we show via simulation study that the proposed likelihood ratio method using an asymptotic chi-square mixture distribution performs well as sample size increases. We compare the behaviors of the two models using the profile likelihood approach under a semiparametric setting. The proposed method is demonstrated using two well-known data sets.     

Should Industrial Policy in Developing Countries Conform to Comparative Advantage or Defy it? A Debate Between Justin Lin and Ha‐Joon Chang

This is the first in an occasional series of DPR Debates, designed to illuminate specific issues of international development policy. Each debate will bring together two well‐known researchers or practitioners, giving them the opportunity, over three rounds, to test and challenge each other's ideas. The debates are intended to be robust but accessible, rooted in rigorous research but useful to the wide readership of Development Policy Review.

Multivariate Synthetic |S| Control Chart with Variable Sampling Interval

A variable sampling interval (VSI) feature is introduced to the multivariate synthetic generalized sample variance |S| control chart. This multivariate synthetic control chart is a combination of the |S| sub-chart and the conforming run length sub-chart. The VSI feature enhances the performance of the multivariate synthetic control chart. The comparative results show that the VSI multivariate synthetic control chart performs better than other types of multivariate control charts for detecting shifts in the covariance matrix of a multivariate normally distributed process. An example is given to illustrate the operation of the VSI multivariate synthetic chart.     

Factors Holding Back Small Third Sector Organizations’ Engagement with the Local Public Sector

In many developed countries there has been a shift from grants to contracts as a source of local public sector funding of the third sector. Smaller third sector organizations may struggle to compete for this funding due to the complex process of accessing and maintaining this funding and conveying their capabilities to funding providers. This study utilizes data from the United Kingdom to determine what factors increase these administrative and communication barriers for smaller organizations. Resources in income and volunteers affect perceptions of the process of obtaining funding. A solution may be standardization of evaluation and monitoring, but this may lead to isomorphism and loss of variety of provision. Better two‐way communication may allow local authorities to retain variety in public service provision through improved knowledge of their partners.     

Combined double sampling and variable sampling interval np chart

A combined double sampling and variable sampling interval (DSVSI) np chart is investigated in this study. The optimal design of the DSVSI np chart is based on minimizing the out-of-control average time to signal. From the numerical results, the DSVSI np chart performs reasonably well in comparison with the standard np chart, double sampling np chart, synthetic double sampling np chart, and other existing np type control charts for detecting increases in the process of fraction non conforming, based on the zero-state case. An example is provided to illustrate the application of the DSVSI np chart.     

Optimal designs of multivariate synthetic |S| control chart based on median run length

The multivariate synthetic generalized sample variance |S| (synthetic |S|) chart is a combination of the |S| sub-chart and the conforming run length sub-chart. A procedure for optimal designs of the synthetic |S| chart, based on the median run length (MRL), for both zero and steady-state modes are provided by minimizing the out-of-control MRL. The comparative results show that the synthetic |S| chart performs better than the standard |S| chart for detecting shifts in the covariance matrix of a multivariate normally distributed process, in terms of the MRL. An example is given to illustrate the operation of the synthetic |S| chart.
