A New Subgraph of Minimum Weight Triangulations

In this paper, two sufficient conditions for identifying a subgraph ofminimum weight triangulation of a planar point set are presented. Theseconditions are based on local geometric properties of an edge to beidentified. Unlike the previous known sufficient conditions for identifyingsubgraphs, such as Keils-skeleton and Yang and Xus double circles, The localgeometric requirement in our conditions is not necessary symmetric withrespect to the edge to be identified. The identified subgraph is differentfrom all the known subgraphs including the newly discovered subgraph:so-called the intersection of local-optimal triangulations by Dickerson etal. An O(n3) time algorithm for finding this subgraph from a set ofn points is presented.     

Reducing Irregular Migration from China

With the development of China's economy since 1979, a new type of Chinese migration has emerged, which is more diversified and quite distinct from previous migration patterns. Trafficking in human beings and other forms of irregular migration are one of the most pressing and complex human rights issues today, reaching across borders and affecting most of the countries in the world, with new and serious security implications. As part of the international irregular migration flows toward and into the European Union (EU), the Chinese, particularly from Fujian and Zhejiang provinces, have played a major role since the 1980s. To some extent, it could be said that China provides the largest number of East Asian irregular immigrants to Europe. Based on fieldwork conducted in southern China over the past seven years, this paper proposes to examine current Chinese irregular migration trends. It will further present the Government's response regarding the migratory modus operandi and policy implications with the aim of offering policy makers an empirical insight into the most active region of emigration in China. Because of the difficulty and sensitivity involved in collecting data on the topic, materials in this paper are mainly based on a content analysis of local Chinese newspapers and my interviews with various people involved in irregular migration activities, such as “snakeheads”, illegal migrants and their family members, and police, local, and government officials at different levels.     

Property rights, collective sales and government intervention: averting a tragedy of the anticommons

In response to the need to cater for the requirements of a larger future population, the Urban Redevelopment Authority of Singapore released development guide plans, which have provided for higher development intensity to residential land in various parts of the island. One of the impacts is that many property owners in Singapore have banded together to capitalize on the “marriage value” of the en bloc site to reap big windfalls as compared to individual sales. But there were minority owners who objected to the sale. The Land Titles (Strata) (Amendment) Act 1999 was passed on 11 October 1999 to facilitate such en bloc sales as these will release prime land for higher density redevelopment to provide more quality private housing in land-scarce Singapore. This paper shows how property rights and property ownership could have led to a tragedy of the anticommons and how government intervention through legislation has averted such a tragedy. Whilst the Land Titles (Strata) (Amendment) Act 1999 has been successful in facilitating en bloc sales resulting in optimization of scarce land resources, it has raised controversial issues such as majority rule versus minority protection and the attenuation of property rights. The authors conclude that in land-scarce Singapore, public good, in that more land will be made available for private housing for the majority, should take precedence.     

Women's Migration for Domestic Work and Cross‐Border Marriage in East and Southeast Asia: Reproducing Domesticity,Contesting Citizenship

This article offers an integrative review of the literature on women's migration for domestic work and cross‐border marriages in East and Southeast Asia. By bringing these two bodies of literature into dialogue, we illuminate the interconnected processes that shape two key forms of women's migration that are embedded in the reproduction of women's domesticity. We highlight structural analyses of the demographic and socio‐economic shifts that propel women's migration while also attending to the affective dimension of migrant women's desires and duties and to the brokerages that mediate the migrant flow. We finally examine how migrant wives and domestic workers contest the boundary of citizenship as they claim their full personhood against divergent modes of control over their rights, bodies, and mobility. We conclude by pointing out concrete areas where the two sets of literature can enrich each other for future research on gender, labor, and migration.     

p-Value for two-Sample Linear Rank Tests Using Permutation Simulations and the Normal Approximation Method

Test statistics from the class of two-sample linear rank tests are commonly used to compare a treatment group with a control group. Two independent random samples of sizes m and n are drawn from two populations. As a result, N = m + n observations in total are obtained. The aim is to test the null hypothesis of identical distributions. The alternative hypothesis is that the populations are of the same form but with a different measure of central tendency. This article examines mid p-values from the null permutation distributions of tests based on the class of two-sample linear rank statistics. The results obtained indicate that normal approximation-based computations are very close to the permutation simulations, and they provide p-values that are close to the exact mid p-values for all practical purposes.     

Subtypes of Nonsocial Play and Psychosocial Adjustment in Malaysian Preschool Children

This study examined subtypes of nonsocial play and their relation to psychosocial adjustment in Malaysian preschool children (N = 141, 72 boys, M age = 4.65 years). Confirmatory factor analyses revealed that a three‐factor model that distinguished social reticence, solitary‐active play, and solitary‐passive play fit the data reasonably well, and also fit the data better than the alternative one‐ and two‐factor models. The distinction among the three subtypes of nonsocial play was found for both boys and girls. Controlling for children's age, gender, and parents' education, social reticence was related to teachers' ratings of anxious behavior, unsociability, and peer exclusion. Solitary‐active play was associated with parents' ratings of inattentiveness, child difficultness, and teachers' ratings of hyperactivity–distractibility. Solitary‐passive play was related to teachers' ratings of unsociability. The findings provide support for a multidimensional view of nonsocial play in Malaysian children.     

Estimating the Hurst parameter in financial time series via heuristic approaches

This research investigates long memory financial equity markets using three heuristic methodologies namely a proposed modified variance time-aggregated plot, modified rescaled-range plot and periodogram approaches. The intensity of the long memory process is quantified in terms of Hurst parameter (H). Five Malaysian equity market indices are selected in the empirical studies with the inclusion of pre- and post-drastic economic events. Our empirical results evidenced dissimilar long memory behaviours in the different regimes of significant economic events. It is also found that after the short-memory adjustment, all the equity markets exhibited substantial reductions in long memory estimations.     

‘Ch'us mon propre Bescherelle’: Challenges from the Hip‐Hop nation to the Quebec nation1

We examine the uses of and attitudes towards language of members of the Montreal Hip‐Hop community in relation to Quebec language‐in‐education policies. These policies, implemented in the 1970s, have ensured that French has become the common public language of an ethnically diverse young adult population in Montreal. We argue, using Blommaert's (2005) model of orders of indexicality, that the dominant language hierarchy orders established by government policy have been both flattened and reordered by members of the Montreal Hip‐Hop community, whose multilingual lyrics insist: (1) that while French is the lingua franca, it is a much more inclusive category which includes ‘Bad French,’ regional and class dialects, and European French; and (2) that all languages spoken by community members are valuable as linguistic resources for creativity and communication with multiple audiences. We draw from a database which includes interviews with and lyrics from rappers of Haitian, Latin‐American, African‐American and Québécois origin.     

Factors associated with mobile health information seeking among Singaporean women

This study examined effects of age and social psychological factors on women’s willingness to be mobile health information seekers. A national survey of 1,878 Singaporean women was conducted to obtain information on women’s mobile phone usage, experiences of health information seeking, and appraisals of using mobile phones to seek health information. Results showed that young, middle-aged, and older women exhibited distinct mobile phone usage behaviors, health information-seeking patterns, and assessments of mobile health information seeking. Factors that accounted for their mobile information-seeking intention also varied. Data reported in this study provide insights into mobile health interventions in the future.
