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.     

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.     

EXAMINING THE EXTERNALITY OF UNEMPLOYMENT INSURANCE ON CHILDREN'S EDUCATIONAL ACHIEVEMENT

I exploit differences in the generosity of unemployment insurance (UI) benefits across states and over time to investigate the link between UI and children's academic achievement. Estimates show that a 1% increase in maximum weekly UI benefits reduces the probability that a child repeats a grade by around 0.03 percentage points. The effect is concentrated among children of low‐ and middle‐income families. This paper's findings, which are the first in the literature to show evidence of a positive effect of UI on children's educational outcomes, provide insight into the role of UI in the human capital accumulation of children.

English and discourses of commodification among tourism workers in the Himalayas

In this article, I investigate commodification discourses and ideologies of English from the perspective of Nepali tourism workers. Drawing data from interviews with porters and trekking guides in Nepal, I argue that English is not seen as merely a transactional means to convey meaning; it works in combination with the traditional form of labor and care in the local economy, establishing itself as a powerful tool to establish closer interpersonal relationships, enhance such interpersonal relationships for economic gains and commodify local identities and cultures in the tourism market. The interview and ethnographic details show that language learners are agentive and capable of making sense of their actions by positioning themselves variously in terms of ethnicity, economic class and job category. These workers think that tourists' linguistic and financial resources are the empowering tools that enable them to travel to locations that they want. They also want to empower themselves with English skills and translocal imaginaries to travel and see the world beyond their immediate reach. Repertoires in English are considered as instruments to mediate their imaginaries and the foreign worlds they want to be part of.     

Breaking Bad: Comparing Gambling Harms Among Gamblers and Affected Others

This article examines gambling harms from both gamblers and affected others’ perspectives. Participants (3076 gamblers and 2129 affected others) completed a retrospective survey that elicited information on harms they experienced from gambling across their lifetime. Their responses were analyzed through testing measurement invariance, estimating item-response theoretic parameters, calculating percentages, confidence intervals, and correlations, as well as regressions. The results indicated large commonalities in the experience of harms reported by gamblers and affected others. Further, gamblers appeared to ‘export’ about half of the harms they experienced to those around them. The findings also provided detailed profiles of evolving harms as problem gambling severity varies.     

Making quality a fundamental part of strategy

All that is known about strategy and strategic planning indicates that quality is a major factor in gaining competitive advantage. It is cost effective, profitable, promotes corporate longevity and builds an important company value system. The authors argue that is too important a factor to be left solely to quality control personnel or planners and is a fundamental part of the chief executive's responsibility for the development of strategy.     

Blunders in international marketing: Fact or fiction

Popular literature on international marketing gives the impression that U.S. firms are insensitive, lack understanding of the unique socio-political, cultural and trade environments of foreign markets, and are probably blundering all the time. Is this really so? To find an answer to this question, this article reports the results of the study that was conducted to verify some of the more publicized blunders in international marketing.     

Growth and Heat Resistance Kinetic Variation Among Various Isolates of Salmonella and its Application to Risk Assessment

The abilities of cells of a particular type of bacteria to leave lag phase and begin the process of dividing or surviving heat treatment can depend on the serotypes or strains of the bacteria. This article reports an investigation of serotype-specific differences in growth and heat resistance kinetics of clinical and food isolates of Salmonella. Growth kinetics at 19 degrees C and 37 degrees C were examined in brain heart infusion broth and heat resistance kinetics for 60 degrees C were examined in beef gravy using a submerged coil heating apparatus. Estimates of the parameters of the growth curves suggests a small between-serotype variance of the growth kinetics. However, for inactivation, the results suggest a significant between-serotype effect on the asymptotic D-values, with an estimated between-serotype CV of about 20%. In microbial risk assessment, predictive microbiology is used to estimate growth and inactivation of pathogens. Often the data used for estimating the growth or inactivation kinetics are based on measurements on a cocktail--a mixture of approximately equal proportions of several serotypes or strains of the pathogen being studied. The expected growth or inactivation rates derived from data using cocktails are biased, reflecting the characteristics of the fastest growing or most heat resistant serotype of the cocktail. In this article, an adjustment to decrease this possible bias in a risk assessment is offered. The article also presents discussion of the effect on estimating growth when stochastic assumptions are incorporated in the model. In particular, equations describing the variation of relative growth are derived, accounting for the stochastic variations of the division of cells. For small numbers of cells, the expected value of the relative growth is not an appropriate "representative" value for actual relative growths that might occur.     

A simulation analysis of the impact of family configuration on virtual cellular manufacturing

Past research has shown that it is possible to simultaneously achieve the setup efficiencies of traditional cellular manufacturing systems and the routeing flexibility of a job shop by viewing cells not as permanent, physical structures, but as temporary, 'virtual' entities. This research demonstrates that the advantages of virtual manufacturing cells can be obtained over a range of part family configurations. In particular, virtual cellular manufacturing is robust to changes in the number and size of families being processed. Further, the research shows that the benefits can be obtained under setup conditions impartial to a family-oriented part environment.
