Language as Both Human Capital and Ethnicity1

In this study, we estimate earnings differentials for knowledge of thirteen minority languages in Canada's three largest urban area. We find that conditional on knowledge of a majority language, knowledge of a minority language is associated with lower earnings. However, the negative differential diminishes for those languages with large local populations. This suggests a positive human capital effect which is for the most part swamped by a negative factor. We argue that this factor is a reflection of ethnicity operating either through ethnolinguistic labor market enclaves or labor market discrimination against minorities.     

A Numerical Solution to the Nonhomogeneous Two-Stage MVK Model of Cancer

In this article, we describe a straightforward method for solving the probability of at least one malignant cell by time t, and the associated hazard function, in the general (i.e., nonhomogeneous) two-stage Moolgavkar-Venzon-Knudson (MVK) model of cancer. The method consists of solving four coupled ordinary differential equations derived from the Kolmogorov backward equations for this process. The relationship of this method to previously proposed solutions is discussed.     

Which Child Immigrants Face Earnings Disparity? Age‐at‐immigration,Ethnic Minority Status and Labour Market Attainment in Canada

Using Canadian Census microdata from 1990 to 2005, we investigate the earnings attainment of immigrants to Canada in 6 age‐at‐arrival cohorts. In comparison to past work we extend our understanding regarding three dimensions of the age at immigration debate: we explore heterogeneity across fine grained age‐at‐arrival cohorts, over a fifteen‐year period and across different ethnic groups. We find that white immigrants and female immigrants arriving in Canada prior to age 18 face little earnings disparity. In contrast, visible minority male immigrants face significant earnings disparity regardless of their age‐at‐migration, and additionally this disparity increases sharply with age‐at‐migration. We find a break in earnings attainment at an age‐of‐arrival of 17, with immigrants arriving after this age performing much worse than those arriving at this age or earlier. The patterns observed are found for visible minority immigrants as a whole, and for Chinese, South Asian and African/Black origin immigrants examined separately.     

Multiple facility location on a network with linear reliability order of edges

We study the problem of locating facilities on the nodes of a network to maximize the expected demand serviced. The edges of the input graph are subject to random failure due to a disruptive event. We consider a special type of failure correlation. The edge dependency model assumes that the failure of a more reliable edge implies the failure of all less reliable ones. Under this dependency model called Linear Reliability Order (LRO) we give two polynomial time exact algorithms. When two distinct LRO’s exist, we prove the total unimodularity of a linear programming formulation. In addition, we show that minimizing the sum of facility opening costs and expected cost of unserviced demand under two orderings reduces to a matching problem. We prove NP-hardness of the three orderings case and show that the problem with an arbitrary number of orderings generalizes the deterministic maximum coverage problem. When a demand point can be covered only if a facility exists within a distance limit, we show that the problem is NP-hard even for a single ordering.     

Exploring the role of faith in resettlement among Muslim Syrian refugees

ABSTRACT

Over 95% of the refugees from Syria who have resettled in the United States are Muslim. The purpose of this qualitative study was to explore the role of the Islamic faith in contributing to resiliency among recently resettled refugees from Syria. Ten in-depth, semi-structured interviews were conducted with Syrian adults who had arrived in the United States between 3 months and 2 years prior to the study. Findings emphasized the primary role of the Islamic faith in the lives of participants. For participants in this study, identifying as Muslim was an essential part of their identity and served as a source of comfort, strength, pride, and humility. Parents in the study expressed fears that their children would lose their connection to their culture and would grow up to devalue the Islamic faith and traditional religious practices due to their exposure to American values which they viewed less strict regarding dress, alcohol consumption, and faith practices. Understanding the important role that the Islamic faith can have in providing a source of comfort, strength, and empowerment for Syrian refugees, and working to build infrastructure to support and sustain these faith traditions is an essential component of refugee resettlement in the United States.     

On tail behaviour of kth upper order statistics under fixed and random sample sizes via tail equivalence

For a fixed positive integer k, limit laws of linearly normalized kth upper order statistics are well known. In this article, a comprehensive study of tail behaviours of limit laws of normalized kth upper order statistics under fixed and random sample sizes is carried out using tail equivalence which leads to some interesting tail behaviours of the limit laws. These lead to definitive answers about their max domains of attraction. Stochastic ordering properties of the limit laws are also studied. The results obtained are not dependent on linear norming and apply to power norming as well and generalize some results already available in the literature. And the proofs given here are elementary.     

扁平世界中的学习型社区:对中国的分析

中国崛起为先进经济体的可能性为其他国家提供了颇为有趣的发展机遇.本文将主要探讨在地域辽阔、人口众多的中国,能否应用知识政策缩小发达地区和欠发达地区之间的种种差异.本文尤为关注发展学习型社区能否填补知识的鸿沟,弥补发展的差距.根据扁平世界理论,世界可以转化为一个公平的游戏场.中国历史悠久,地缘政治复杂,中国的历史教训为发展中国家众多怀抱梦想的社区提供了各种各样的经验教训.基于这一原因,我们将中国加以个案考察.中国发明了印刷术、火药,开启了足球运动(兹不一一列举),却在其巅峰时期建造了长城(本身就是一个工程上的奇迹),与世隔绝,此后日渐衰微,直至欧洲列强的火炮打开了国门,在沿海设立通商口岸,惊醒了中国人.事实上,已有学者论述,是邓小平的改革开放扭转了这一悲惨状态.此种观点未免过于简单,本文不敢苟同.本文认为,旧中国的衰败,并非由于国门的开放或关闭,而是由于缺少知识和衡量知识的标准.     

Healthcare in India: Changing the Financing Strategy

The way in which healthcare is financed is critical for equity in access to healthcare. At present the proportion of public resources committed to healthcare in India is one of the lowest in the world, with less than one‐fifth of health expenditure being publicly financed. India has large‐scale poverty and yet the main source of financing healthcare is out‐of‐pocket expenditure. This is a cause of the huge inequities we see in access to healthcare. The article argues for strengthening public investment and expenditure in the health sector and suggests possible options for doing this. It also calls for a reform of the existing healthcare system by restructuring it to create a universal access mechanism which also factors in the private health sector. The article concludes that it is important to over‐emphasize the fact that health is a public or social good and so cannot be left to the vagaries of the market.
