Go North, Young Scholar, Go North
Authors: White Graham 
Published: March 2012

Abstract.The North—defined as the Canadian Arctic—ranks among the most understudied and yet the most promising fields of enquiry for Canadian political scientists. It offers a host of fascinating research topics and intellectual puzzles, many of which entail the often fraught relationship between the Canadian state and Aboriginal peoples. Important conceptual issues await academics studying northern politics and governance. As well, political scientists' work can benefit the governments and the people of the North who are grappling with difficult practical problems as they develop distinctive ways of governing themselves.Academic work on northern politics can be at once intellectually stimulating, professionally rewarding and of significant practical utility. Accordingly, more Canadian political scientists, especially young scholars, should turn their attention northwards.Résumé.Le Nord, ou plus précisément l'Arctique canadien, constitue un des champs les moins explorés et pourtant les plus prometteurs pour les politologues canadiens. Son étude révèle une foule de sujets de recherche fascinants et d'énigmes intellectuelles, dont plusieurs se rapportent aux relations souvent tendues entre l'État canadien et les peuples autochtones. D'importants enjeux conceptuels se posent aux chercheurs de la politique nordique et de la gouvernance. De plus, les recherches des politologues peuvent aider les gouvernements et les habitants du Nord à résoudre des problèmes concrets associés au développement de façons distinctives de se gouverner.En somme, la recherche sur la politique nordique peut être à la fois intellectuellement stimulante, professionnellement gratifiante et pourvu d'une grande utilité pratique. En conséquence, plus de politologues canadiens, et en particulier ceux des nouvelles générations, devraient diriger leur attention vers le Nord.

Abstract.The gradual withdrawal of young voters from the active electorate is one of the strongest and most important factors in accounting for declining voter turnout in Canada and other western democracies. Because qualitative approaches may be better able to probe the reasons underlying these changing values and attitudes than traditional mass surveys, we used the popular social media site Facebook during the 2008 federal election campaign to collect data on young people's perceptions of electoral politics in the context of their civic obligations. This medium proved to be a valuable and productive research tool. Based on this project, we argue that non-voting tends to be seen as a more socially acceptable behaviour to young voters than is typically found in the thinking of older cohorts, and that this may be connected to changing concepts of the obligations of citizenship.Résumé.Le désengagement graduel des jeunes électeurs est un des facteurs les plus importants pour expliquer le déclin de la participation électorale au Canada et dans les démocraties occidentales. Afin de mieux comprendre les causes de ce changement de valeurs et d'attitudes, nous avons utilisé le média socialFacebookafin de collecter des données qualitatives sur la perception des jeunes électeurs durant l'élection fédérale de 2008. Cette approche nous apparaît mieux adapter que l'approche traditionnelle caractérisée par l'utilisation de sondages d'opinion. Au terme de l'analyse, la collecte de données viaFacebooks'est avérée être une stratégie de recherche productive. En nous basant sur ces données, nous concluons que l'abstention électorale est un comportement plus socialement acceptable pour les jeunes électeurs que pour les électeurs plus âgés. Cette attitude pourrait être liée un changement conceptuel quant aux obligations associées à la citoyenneté.
Vers une bureaucratie représentative. La promotion de la représentation et de la diversité linguistiques dans l'administration fédérale en Suisse et au Canada

Résumé.Sous l'angle du concept de bureaucratie représentative, le présent article compare la gestion des enjeux liés à la participation des différentes communautés linguistiques dans l'administration publique de deux États multilingues : le Canada et la Suisse. À la suite de la mobilisation politique autour du clivage linguistique, des stratégies de promotion du plurilinguisme ont été adoptées dans les deux pays. La stratégie canadienne mise surl'égalité de traitementdes fonctionnaires anglophones et francophones. La Suisse poursuit quant à elle l'objectif de lareprésentationdes différentes communautés linguistiques dans la fonction publique. Ces différences de fond s'expliquent, entre autres, par la nature du régime linguistique en place et par le contexte de démocratie consociationnelle en Suisse. La participation proportionnelle des communautés linguistiques au sein de l'administration fédérale est globalement atteinte dans les deux pays. Cependant, au niveau du fonctionnement interne, une logique de rationalité linguistique exerce une pression sur les groupes minoritaires pour qu'ils adoptent la langue majoritaire.Abstract.Drawing on the concept of representative bureaucracy, this article examines how two multi-lingual states—Canada and Switzerland—deal with issues related to the participation of different linguistic communities in the federal public service. Following a political mobilisation of the linguistic cleavage, strategies to promote multilingualism in the public service have been adopted in both countries. The Canadian strategy focuses onequal treatmentof Anglophones and Francophones in the public service. In Switzerland,adequate representationof the linguistic communities is the primary goal. These differences are explained by the characteristics of the linguistic regimes in each of the two countries, as well as by the peculiarities of consociational democracy in Switzerland. In both countries, the linguistic origins of public administration staff, overall, mirrors the proportions of the linguistic communities in the wider society. Within administrative units, however, linguistic diversity is hampered by the logics of language rationality, where minorities are under pressure to communicate in the language of the majority.

SUMMARYFive tropical multi-purpose tree species (MPTS), Enterolobium cyclocarpum, Moringa oleifera, Millettia griffoniana, Pterocarpus santalinoides and Treculia Africana, and one exotic species (Leucaena leucocephala), which acted as the control, planted in a randomized complete block design, were selected to evaluate the potentials as feed supplements for herds in dry seasons of south-western Nigeria. Samples of the MPTS leaves were collected in 2005, 2006, 2007 and 2008, weighed, dried and milled for estimation of biomass production, chemical analysis and measurement of in vitro gas production. Results showed significant differences (P < 0·001) in the biomass production of the MPTS. E. cyclocarpum consistently recorded the highest biomass production, height and collar diameter throughout the experimental period. There were also differences (P ⩽ 0·001) in dry matter (DM), crude protein (CP), ether extract (EE) and ash contents of the MPTS across species and years after planting. M. oleifera recorded the highest CP content of 240 g/kg DM. Interactions were observed between species and year for neutral detergent fibre (NDFom), acid detergent fibre (ADFom) and lignin contents of the MPTS. M. griffoniana and M. oleifera had lower tannin contents, whereas E. cyclocarpum, P. santalinoides, T. africana and L. leucocephala had higher tannin contents. The values reported for mineral contents showed that their levels in the MPTS were adequate for ruminants and there were no differences in the contents of most minerals. In vitro gas production results showed that the potential gas production ‘b’ was highest in M. griffoniana and lowest in P. santalinoides and there were species and year interactions (P ⩽ 0·001) for volatile fatty acid profiles of the supernatant after 96 h incubation. The estimated organic matter digestibility (OMD) and metabolizable energy (ME) of the MPTS were generally high. The high biomass production, CP and low fibre contents, as well as in vitro fermentation characteristics found for the MPTS evaluated in the current study suggest that these are better alternatives in comparison with L. leucocephala. It can be concluded that the MPTS evaluated have potential as sources of feed supplements for ruminants in dry seasons, especially in south western Nigeria.
‘Do you own non-Chinese mui tsai?’ Re-examining Race and Female Servitude in Malaya and Hong Kong, 1919–1939
Authors: LEOW RACHEL 
Published: March 2012

AbstractThis paper considers the abolition of the mui tsai (young female bondservants) as it unfolded in British Malaya, and challenges the overemphasis on Hong Kong as the primary focus of mui tsai scholarship. While the mui tsai system was defended as a time-honoured Chinese tradition, this paper uses new material to show that trans-racial considerations figured prominently in mui tsai abolition in Malaya, particularly in helping to recast it as a wider problem of child welfare. It is argued that this neglected aspect of mui tsai abolition only comes clearly to light in the Malayan case; for only in the intensely multi-racial conditions of peninsular Malaya could the question be asked: ‘Do you own non-Chinese mui tsai?’
Hebrew School in Nineteenth-Century Bombay: Protestant Missionaries, Cochin Jews, and the Hebraization of India's Bene Israel Community
Authors: NUMARK MITCH 
Published: March 2012

AbstractThis paper is a study of cultural interaction and diffusion in colonial Bombay. Focusing on Hebrew language instruction, it examines the encounter between India's little-known Bene Israel Jewish community and Protestant missionaries. Whilst eighteenth and nineteenth-century Cochin Jews were responsible for teaching the Bene Israel Jewish liturgy and forms of worship, the Bene Israel acquired Hebrew and Biblical knowledge primarily from nineteenth-century Protestant missionaries. At the beginning of the nineteenth century, the Bene Israel community was a Konkanjatiwith limited knowledge of Judaism. However, by the end of the century the community had become an Indian-Jewish community roughly analogous to other Jewish communities. This paper explores how this transformation occurred, detailing the content, motivation, and means by which British and American missionaries and, to a lesser extent, Cochin Jews instructed the Bene Israel in Jewish knowledge. Through a critical examination of neglected English and Marathi sources, it reconstructs the Bene Israel perspective in these encounters and their attitude towards the Christian missionaries who laboured amongst them. It demonstrates that the Bene Israel were active participants and selective consumers in their interaction with the missionaries, taking what they wanted most from the encounter: knowledge of the Old Testament and the Hebrew language. Ultimately, the instruction the Bene Israel received from Protestant missionaries did not convert them to Christianity but strengthened and transformed their Judaism.
Cryptic extinction of a common Pacific lizardEmoia impar(Squamata, Scincidae) from the Hawaiian Islands
Authors: Fisher Robert , Ineich Ivan 
Published: March 2012

AbstractMost documented declines of tropical reptiles are of dramatic or enigmatic species. Declines of widespread species tend to be cryptic. The early (1900s) decline and extinction of the common Pacific skinkEmoia imparfrom the Hawaiian Islands is documented here through an assessment of literature, museum vouchers and recent fieldwork. This decline appears contemporaneous with the documented declines of invertebrates and birds across the Hawaiian Islands. A review of the plausible causal factors indicates that the spread of the introduced big-headed antPheidole megacephalais the most likely factor in this lizard decline. The introduction and spread of a similar skinkLampropholis delicataacross the islands appears to temporally follow the decline ofE. impar, although there is no evidence of competition between these species. It appears thatL. delicatais spreading to occupy the niche vacated by the extirpatedE. impar. Further confusion exists because the skinkE. cyanura, which is very similar in appearance toE. impar, appears to have been introduced to one site within a hotel on Kaua'i and persisted as a population at that site for approximately 2 decades (1970s–1990s) but is now also extirpated. This study highlights the cryptic nature of this early species extinction as evidence that current biogeographical patterns of non-charismatic or enigmatic reptiles across the Pacific may be the historical result of early widespread invasion by ants. Conservation and restoration activities for reptiles in the tropical Pacific should consider this possibility and evaluate all evidence prior to any implementation.
Programmed cell death in Giardia

Published: March 2012

SUMMARYProgrammed cell death (PCD) has been observed in many unicellular eukaryotes; however, in very few cases have the pathways been described. Recently the early divergent amitochondrial eukaryote Giardia has been included in this group. In this paper we investigate the processes of PCD in Giardia. We performed a bioinformatics survey of Giardia genomes to identify genes associated with PCD alongside traditional methods for studying apoptosis and autophagy. Analysis of Giardia genomes failed to highlight any genes involved in apoptotic-like PCD; however, we were able to induce apoptotic-like morphological changes in response to oxidative stress (H2O2) and drugs (metronidazole). In addition we did not detect caspase activity in induced cells. Interestingly, we did observe changes resembling autophagy when cells were starved (staining with MDC) and genome analysis revealed some key genes associated with autophagy such as TOR, ATG1 and ATG 16. In organisms such as Trichomonas vaginalis, Entamoeba histolytica and Blastocystis similar observations have been made but no genes have been identified. We propose that Giardia possess a pathway of autophagy and a form of apoptosis very different from the classical known mechanism; this may represent an early form of programmed cell death.

BackgroundPatients with schizophrenia have excess cardiovascular morbidity and mortality. Previous studies suggest that this may be partly due to inadequate somatic treatment and care, such as non-optimal use of lipid-lowering and antihypertensive pharmacotherapy, but longitudinal studies on such aetiological pathways are scarce.MethodWe investigated the use of lipid-lowering and antihypertensive pharmacotherapy, and the risk of hospitalization for and death from coronary heart disease and stroke among patients with schizophrenia in a birth cohort of 12 939 subjects (Helsinki Birth Cohort Study). This cohort was followed for over 30 adult years by using national databases on cardio- and cerebrovascular hospitalizations and mortality and on reimbursement entitlements and use of drugs for treatment of hypertension, dyslipidaemia, coronary heart disease and diabetes.ResultsIndividuals with schizophrenia had a higher risk of hospitalization for coronary heart disease [hazard ratio (HR) 1.65, 95% confidence interval (CI) 1.03–2.57], and mortality from this disease was markedly higher (HR 2.92, 95% CI 1.70–5.00), particularly among women (p=0.001 for women, p=0.008 for men). Women with schizophrenia had also marginally increased stroke mortality (p=0.06). However, patients with schizophrenia used less lipid-lowering (odds ratio 0.47, 95% CI 0.27–0.80) and antihypertensive drug treatment (HR 0.37, 95% CI 0.22–0.61).ConclusionsIn this longitudinal study, coronary heart disease morbidity was increased and coronary heart disease mortality markedly increased in patients, especially in women with schizophrenia. These patients nevertheless received less antihypertensive and lipid-lowering treatment.

Published: March 2012

In the middle years of the 20th Century, few merchant ships were fitted with radar and, on those that were, shipmasters often looked upon it as a distraction from a watchkeeper's proper duties rather than as a useful aid to navigation.For shipmasters of that persuasion, the only place to keep watch was outside the wheelhouse on an exposed bridge wing; mostly the starboard wing because the COLREGS (‘Collision Regulations’ or, more properly, ‘The International Regulations for Preventing Collisions at Sea’) required us to give way to ships approaching from the starboard side. Well, the bridge wing was an attractive place to spend a few hours on a calm, tropical night, but it could be highly disagreeable and sometimes, I thought, actually dangerous, in a North Atlantic rainstorm.

A tree T is said to be homogeneous if it is uniquely rooted and there exists an integer b ≥ 2, called the branching number of T, such that every t ∈ T has exactly b immediate successors. We study the behaviour of measurable events in probability spaces indexed by homogeneous trees.Precisely, we show that for every integer b ≥ 2 and every integer n ≥ 1 there exists an integer q(b,n) with the following property. If T is a homogeneous tree with branching number b and {At:t ∈ T} is a family of measurable events in a probability space (Ω,Σ,μ) satisfying μ(At)≥ϵ>0 for every t ∈ T, then for every 0<θ<ϵ there exists a strong subtree S of T of infinite height, such that for every finite subset F of S of cardinality n ≥ 1 we have

In fact, we can take q(b,n)= ((2b−1)2n−1−1)·(2b−2)−1. A finite version of this result is also obtained.

AbstractIntroductionThe aim of the present study was to explore the relationship between subthreshold mood symptoms and suicidality in patients with complicated grief (CG).MethodsFifty patients with CG were included in the study and evaluated by the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis-I disorders, the Inventory of Complicated Grief, and the Mood Spectrum Self Report (MOODS-SR) lifetime version, to evaluate the subthreshold mood symptoms.ResultsTwenty-eight patients (56%) reported lifetime suicidal ideation and 11 patients (22%) reported suicide attempts. Subthreshold depressive and rhythmicity/vegetative functions items of the MOODS-SR were significantly associated with increased suicidal ideation and attempts, while subthreshold manic items were associated with suicidal ideation only. Relationships were confirmed after controlling for Axis-I disorders comorbidity.ConclusionThe results of the present study suggest the usefulness of exploring lifetime subthreshold mood symptoms in CG patients, in order to promptly identify those who may be more prone to suicidality.

AbstractExposure to stress and hallucinogens in adulthood evokes persistent alterations in neurocircuitry and emotional behaviour. The structural and functional changes induced by stress and hallucinogen exposure are thought to involve transcriptional alterations in specific effector immediate early genes. The immediate early gene, activity regulated cytoskeletal-associated protein (Arc), is important for both activity and experience dependent plasticity. We sought to examine whether trophic factor signalling through brain-derived neurotrophic factor (BDNF) contributes to the neocortical regulation of Arc mRNA in response to distinct stimuli such as immobilization stress and the hallucinogen 2,5-dimethoxy-4-iodoamphetamine (DOI). Acute exposure to either immobilization stress or DOI induced Arc mRNA levels within the neocortex. BDNF infusion into the neocortex led to a robust up-regulation of local Arc transcript expression. Further, baseline Arc mRNA expression in the neocortex was significantly decreased in inducible BDNF knockout mice with an adult-onset, forebrain specific BDNF loss. The induction of Arc mRNA levels in response to both acute immobilization stress or a single administration of DOI was significantly attenuated in the inducible BDNF knockout mice. Taken together, our results implicate trophic factor signalling through BDNF in the regulation of cortical Arc mRNA expression, both under baseline conditions and following stress and hallucinogen exposure. These findings suggest the possibility that the regulation of Arc expression via BDNF provides a molecular substrate for the structural and synaptic plasticity observed following stimuli such as stress and hallucinogens.
On nitrogen fixation and preferential remineralization of phosphorus
Authors: Monteiro F. M. , Follows M. J. 
Published: March 2012

Regional and global nitrogen fixation rates are often estimated from geochemical tracers related to N* (= NO3− − 16PO43−). However the patterns of this tracer reflect the influence of numerous processes including nitrogen fixation, denitrification, remineralization of organic matter, variable stoichiometry, atmospheric deposition and physical transport. Here we have used idealized models to illustrate how preferential remineralization of organic phosphorous may explain observed features of N* distribution in the North Atlantic Ocean, including a subsurface maximum and an increased temporal variability in the mid‐thermocline. If preferential remineralization of phosphorus is key in shaping the oceanic distribution of N*, published estimates of nitrogen fixation may be underestimating the marine nitrogen fixation rate by as much as a factor of three.
