In his contribution, Joppke justifies his selection of foundational scholars by linking each to what he sees as the three key facets of citizenship: status, rights and identity. Maarten Vink explicitly links his research agenda to the first, status, and outlines why it is so important. In identifying three facets of citizenship, Joppke acknowledges that some academics would include political participation, but he ultimately decides against it. But here we can, and should, broaden citizenship studies by bringing in insights from the behavioral politics tradition in domestic politics - when and why people engage in political acts - and from the social movements literature in sociology. I believe that the American debate on immigration reform, admittedly stalled, would not have advanced as far as it has without the social movement activism of DREAMers - unauthorized young people pushing for a path to citizenship - and the belief that Barack Obama won re-election in part because of the Latino vote. Importantly, one type of political activism demands formal citizenship, the other does not. As many contributors note, the “national models” approach has had a significant impact on citizenship studies. Whether one views such models through a cultural, institutional or historical lens, this tends to be a top-down, macro-level framework. What about immigrants’ agency? In Canada, although the ruling Conservative government is shifting citizenship discourse to a more traditional language - as Winter points out - it has not reduced immigration, ended dual citizenship, or eliminated multiculturalism, all goals of the Reform Party that the current prime minister once helped build. “Lock-in” effects (or policy feedback loops) based on high immigrant naturalization and the coming of age of a second-generation with citizenship also d emands study, in North America and elsewhere. Much of the research thus far suggests that political decisions over citizenship status and rights do not seem linked to immigrants’ political activism. State-centered decision-making may have characterized policy in the early post-World War II period in Europe (and East Asia?), but does it continue to hold today? Majority publics and immigrant-origin residents are increasingly politicized around citizenship and immigration. Does immigrant agency extend citizenship status, rights and identity to those born outside the polity? Is electoral power key, or is protest necessary? How is citizenship practiced, and contested, irrespective of formal status? These are important and understudied empirical questions, ones that demand theoretical creativity - across sub-fields and disciplines - in conceptualizing and understanding citizenship in contemporary times.

Female circumcision was almost unheard of in the United States a few years ago. The recent influx of African immigrants has increased media attention to the subject, leading to laws criminalizing female circumcision. This study examines the reactions of African immigrants living in Houston, Texas, to media portrayal and legislation regarding female circumcision in an attempt to understand the effectiveness of U.S. laws, and media messages in deterring the practice. ^ Through literature reviews the study looks at how female circumcision is portrayed in the Houston Chronicle, and gives detailed discussion of laws regarding it. Attitudes, beliefs, experiences and reactions of African immigrants towards the practice and American's perceptions of female circumcision is examined via a series of case studies. ^ Data show that media and laws portray female circumcision negatively and make little attempt to understand the cultural practice, generating outrage among Africans who would like to see changes in the practice. ^

In this paper we examine the time T to reach a critical number K0 of infections during an outbreak in an epidemic model with infective and susceptible immigrants. The underlying process X, which was first introduced by Ridler-Rowe (1967), is related to recurrent diseases and it appears to be analytically intractable. We present an approximating model inspired from the use of extreme values, and we derive formulae for the Laplace-Stieltjes transform of T and its moments, which are evaluated by using an iterative procedure. Numerical examples are presented to illustrate the effects of the contact and removal rates on the expected values of T and the threshold K0, when the initial time instant corresponds to an invasion time. We also study the exact reproduction number Rexact,0 and the population transmission number Rp, which are random versions of the basic reproduction number R0.

Bioaerosols are a subgroup of atmospheric aerosols and are often linked to the spread of human, animal and plant diseases. Bioaerosols also may play an indirect effect on environmental processes, including the formation of precipitation and alteration of the global climate through their role as nuclei for cloud droplet formation. Several types of biological organisms (e.g., fungi and bacteria) have been shown to be effective ice nuclei (IN) and cloud condensation nuclei (CCN). During 21 days in August 2013 we participated in a collaborative international campaign at a rural, coastal site near the village of Ucluelet on the west coast of Vancouver Island, British Columbia, Canada. The experiments were conducted as part of the NETCARE project (the NETwork on Climate and Aerosols: Addressing Key Uncertainties in Remote Canadian Environments), in part to examine cloud nuclei properties of marine aerosol. The study was conducted from a mobile trailer located approximately 100 m from the coast. A suite of aerosol instrumentation was operated for approximately one month. Key instruments utilized as a part of this thesis include the wideband integrated bioaerosol sensor (WIBS-4A) and the multiple orifice uniform deposition impactor (MOUDI) coupled with an off-line droplet freezing technique (DFT) for the measurement of ice nucleation activity of particles in immersion mode. The WIBS measures the concentration and properties of individual fluorescent particles suspended in the air, which can serve as a proxy for airborne biological particle content. Particles shown to be fluorescent by the WIBS instrument were divided into seven categories based on the pattern of fluorescence each particle exhibited in the three fluorescent channels. Results of the WIBS analysis show that the fluorescent particle concentration in the region correlated well with IN number. The fluorescent particle concentration correlated well with the number of particles shown to be ice active as a function of both particle size and freezing temperature. Correlations involving marine aerosols and marine biological activity indicate that the majority of IN measured at the coastal site likely are not from have marine sources.

Background: Migrant workers have been one of the groups most affected by the economic crisis. This study evaluates the influence of changes in employment conditions on the incidence of poor mental health of immigrant workers in Spain, after a period of 3 years, in context of economic crisis. Methods: Follow-up survey was conducted at two time points, 2008 and 2011, with a reference population of 318 workers from Colombia, Ecuador, Morocco and Romania residing in Spain. Individuals from this population who reported good mental health in the 2008 survey (n = 214) were interviewed again in 2011 to evaluate their mental health status and the effects of their different employment situations since 2008 by calculating crude and adjusted odds ratios (aORs) for sociodemographic and employment characteristics. Findings: There was an increased risk of poor mental health in workers who lost their jobs (aOR = 3.62, 95%CI: 1.64–7.96), whose number of working hours increased (aOR = 2.35, 95%CI: 1.02–5.44), whose monthly income decreased (aOR = 2.75, 95%CI: 1.08–7.00) or who remained within the low-income bracket. This was also the case for people whose legal status (permission for working and residing in Spain) was temporary or permanent compared with those with Spanish nationality (aOR = 3.32, 95%CI: 1.15–9.58) or illegal (aOR = 17.34, 95%CI: 1.96–153.23). In contrast, a decreased risk was observed among those who attained their registration under Spanish Social Security system (aOR = 0.10, 95%CI: 0.02–0.48). Conclusion: There was an increase in poor mental health among immigrant workers who experienced deterioration in their employment conditions, probably influenced by the economic crisis.
