Micro‐Level Determinants of Remittances from Recent Migrants to Canada

Despite considerable interest in remittances to developing countries, the limited availability of large sample data has constrained aspects of our understanding of remitter behaviour. This paper utilizes data from Statistics Canada’s Longitudinal Survey of Immigrants to Canada (LSIC) to investigate how the demographic characteristics of recent immigrants influence their remittance levels shortly after their arrival in Canada. We identify several hypotheses and use a Tobit model to estimate the impact of individual characteristics on remittance choices. As expected, remittances rise with incomes, age and falls with the size of the migrating family, housing costs and education. We also estimate how remittances are affected by other characteristics, such as gender, marital status, religion, region of origin, region of settlement and attitudes towards home and host communities.     

Computer use and ulnar neuropathy: results from a case-referent study

We aimed to evaluate associations between vocational computer use and 1) ulnar neuropathy, and 2) ulnar neuropathy- like symptoms as distinguished by electroneurography. We identified all patients aged 18-65 years, examined at the Department of Neurophysiology on suspicion of ulnar neuropathy, 2001-2007. We mailed a questionnaire to 546 patients with ulnar neuropathy, 633 patients with ulnar neuropathy-like symptoms, and three community referents per case, matched on sex, age, and primary care centre. From a Job Exposure Matrix we extracted estimates of daily hours of computer use. The analysis was performed by conditional logistic regression.There were a negative association between daily hours of computer use and the two outcomes of interest. Participants who reported their elbow to be in contact with their working table for 2 hours or more during the workday had an elevated risk for ulnar neuropathy (OR=2.16, 95 % CI; 1.06-4.44).The two outcomes were not associated with daily hours of computer use. Findings suggested specific effects of pressure on the elbow, and might be an explanation for the overweight of left-sided outcomes in this primarily right-handed group. Preventive efforts would then be straightforward by providing appropriate arm support for the left arm and elbow.     

Ethnic appeal: A self-defense tool for Kenyan politicians

So far, analyses of apologetic rhetoric strategies as used by individuals or organizations to respond to accusations of wrongdoing have been concentrated in the West. An analysis of political apologia in an African setting – in this case Kenya – reveals that while Kenyan politicians have used denial, victimization, mortification, and counterattacking among other self-defense strategies, one particular strategy emerges as the most commonly used by Kenyan politicians – ethnic appeal.     

The effects of pre-IPO corporate activity on newly-public firms' growth

We investigate firms' pre-IPO corporate activity. We find that firms involved in extraordinary – i.e., beyond momentum – amounts of acquisitions, JVs, and alliances in the year leading up to their IPOs (1) are more likely to engage in post-IPO corporate activity; and (2) enter into their first post-IPO transaction twice as fast as other firms. Our results indicate that signaling via extraordinary corporate activity can have a significant effect on entrepreneurial firms’ growth. The implications are discussed.     

Urge to Gamble in Problem Gamblers Exposed to a Casino Environment

Cue-reactivity has received increased attention in addiction research, though not for gambling in particular. We examined cue reactivity in 18 problem gamblers by accompanying them to a gaming casino and measuring their subjective urge to gamble over a 1-h period. Half of the sample was additionally exposed to a gambling-specific negative mood induction (NMI) manipulation via guided imagery. Overall, about two-thirds of the sample reported moderate to high-gambling urges during the casino exposure. Additionally, the NMI reduced cue-reactivity. Finally, gambling urges in both groups decreased over the course of the exposure sessions. These findings suggest that a majority of problem gamblers experience the urge to gamble when exposed to gambling cues and that the intensity of these urges decrease with time, especially in the presence of a gambling-relevant NMI. Cue exposure should be studied further as a potential tool in the treatment of problem gambling.     

Models for the analysis of C-reactive protein in statin trials

Elevation in C-reactive protein (CRP) is an independent risk factor for cardiovascular disease progression and levels are reduced by treatment with statins. However, on-treatment CRP, given baseline CRP and treatment, is not normally distributed and outliers exist even when transformations are applied. Although classical non-parametric tests address some of these issues, they do not enable straightforward inclusion of covariate information. The aims of this study were to produce a model that improved efficiency and accuracy of analysis of CRP data. Estimation of treatment effects and identification of outliers were addressed using controlled trials of rosuvastatin. The robust statistical technique of MM-estimation was used to fit models to data in the presence of outliers and was compared with least-squares estimation. To develop the model, appropriate transformations of the response and baseline variables were selected. The model was used to investigate how on-treatment CRP related to baseline CRP and estimated treatment effects with rosuvastatin. On comparing least-squares and MM-estimation, MM-estimation was superior to least-squares estimation in that parameter estimates were more efficient and outliers were clearly identified. Relative reductions in CRP were higher at higher baseline CRP levels. There was also evidence of a dose-response relationship between CRP reductions from baseline and rosuvastatin. Several large outliers were identified, although there did not appear to be any relationships between the incidence of outliers and treatments. In conclusion, using robust estimation to model CRP data is superior to least-squares estimation and non-parametric tests in terms of efficiency, outlier identification and the ability to include covariate information.     

Is there a European social work identity?

The aim of this paper is to examine whether at this point in time the notion of a ‘European social work identity’ can be sustained. The paper commences with some brief consideration of theories of identity, and particularly draws attention to social constructionist identity theory, highlighting its focus on identity as a process. Ideas about what constitutes ‘collective identity’ are then examined. From this, two particular models of collective identity are presented which are helpful for understanding cultural identities. These are the more ‘traditional’ notion of collective culture being evidenced by the presence of shared histories and traditions, and the more social constructionist view of collective processes and action to form identities – whether imposed by the state or generated by the people – as constitutive of identities in themselves. ‘European identity’, and then ‘European social work identity’, will then be examined using these models of collective identity. The paper concludes that using social constructionist versions of identity (identity as a process of collectivisation), European social work identity can certainly be established.
