Dietary fish oil reduces glomerular injury and elevated renal hydroxyeicosatetraenoic acid levels in the JCR:LA-cprat, a model of the metabolic syndrome
Authors: Aukema Harold M. , Lu Jing , Borthwick Faye , Proctor Spencer D. 
Published: November 2012

We have previously shown nutritional intervention with fish oil (n-3 PUFA) to reduce numerous complications associated with the metabolic syndrome (MetS) in the JCR:LA-corpulent (cp) rat. In the present study, we sought to explore the potential role of fish oil to prevent glomerulosclerosis in JCR:LA-cprats via renal eicosanoid metabolism and lipidomic analysis. Male lean and MetS JCR:LA-cprats were fed a lipid-balanced diet supplemented with fish oil (5 or 10 % of total fat). After 16 weeks of feeding, albuminuria was significantly reduced in MetS rats supplemented with 5 or 10 % fish oil ( − 53 and − 70 %, respectively, compared with the untreated MetS rats). The 5 % fish oil diet resulted in markedly lower glomerulosclerosis ( − 43 %) in MetS rats and to a lesser extent in those supplemented with 10 % fish oil. Interestingly, untreated MetS rats had higher levels of 11- and 12-hydroxyeicosatetraenoic acids (HETE)v.lean rats. Dietary fish oil reduced these levels, as well as other (5-, 9- and 15-) HETE. Whilst genotype did not alter prostanoid levels, fish oil reduced endogenous renal levels of 6-keto PGF1α(PGI2metabolite), thromboxane B2(TxB2), PGF2αand PGD2by approximately 60 % in rats fed 10 % fish oil, and TxB2( − 50 %) and PGF2α( − 41 %) in rats fed 5 % fish oil. In conclusion, dietary fish oil prevented glomerular damage in MetS rats and mitigated the elevation in renal HETE levels. These results suggest a potential role for dietary fish oil to improve dysfunctional renal eicosanoid metabolism associated with kidney damage during conditions of the MetS.
Small Worlds of Diversity: Views toward Immigration and Racial Minorities in Canadian Provinces
Authors: Bilodeau Antoine , Turgeon Luc , Karakoç Ekrem 
Published: November 2012

Abstract.Canadian provinces have long been considered as “small worlds,” each with its own cultural distinctiveness and province-building dynamics. This article examines whether these same provincial specificities are observed in terms of attitudes toward immigration intakes and racial diversity. Three questions are asked. First, are there important variations in views toward immigration and racial minorities across Canadian provinces within the native-born white Canadian population? Second, have the differences and similarities changed between 1988 and 2008? And third, do specific provincial economic, demographic, and cultural realities shape provincial public opinion on these matters? The findings indicate that there are significant differences and commonalities in how all provinces react to immigration and racial diversity, that native-born white Canadians have grown increasingly accepting of immigration and racial diversity over time and that views toward immigration and racial diversity are distinct from each other and each responds to a specific set of provincial realities.Résumé.Les provinces canadiennes constituent de “petits univers,” chacune possédant sa propre culture et sa propre dynamique politique. Cet article explore si de telles spécificités provinciales peuvent être également observées en ce qui a trait aux attitudes par rapport à l'immigration et à la diversité raciale. Nous posons trois questions. Premièrement, y a-t-il des différences d'opinions quant à l'immigration et aux minorités raciales entre provinces canadiennes au sein de la population blanche née au Canada? Deuxièmement, est-ce que les similarités et les différences entre les provinces ont changé entre 1988 et 2008? Et troisièmement, est-ce que les réalités économiques, démographiques et culturelles provinciales influencent l'opinion publique provinciale sur ces questions? Les résultats de l'étude indiquent qu'il y a à la fois des similarités et des différences quant aux attitudes des différentes provinces sur l'immigration et la diversité raciale, que la population blanche née au Canada s'est montrée de plus en plus ouverte à l'immigration et à la diversité raciale au cours de la période à l'étude, et que les attitudes par rapport à l'immigration et la diversité raciale ne sont pas identiques et qu'elles répondent chacune à leur façon à un certain nombre de réalités provinciales.
Canadian Federalism and Change in Policy Attention: A Comparison with the United Kingdom
Authors: Montpetit Éric , Foucault Martial 
Published: November 2012

Abstract. Federal systems empower multiple policy actors from different levels of governments. For some scholars, the disagreements arising within such a diverse group of actors create policy stalemates. Others contend instead that new ideas are more likely to arise and diffuse from such a diverse group. This article is a contribution to this scholarly debate, proposing an original contribution on policy agendas. It argues that both perspectives are useful to understanding the dynamic of policy making within federal systems. Looking at change in policy attention in Canadian and British speeches from the throne, the article argues that federalism constrains change immediately following a party turnover in government. In the following years, however, federal arrangements encourage larger changes in policy attention than arrangements where power is centralized.Résumé. Les systèmes fédéraux rassemblent plusieurs acteurs politiques issus de différents niveaux de gouvernement. Pour certains chercheurs, l'existence de potentiels désaccords entre de tels décideurs est susceptible de créer des impasses politiques. D'autres soutiennent au contraire que les nouvelles idées sont plus susceptibles d'émerger et de se diffuser à partir d'un tel groupe diversifié. Cet article s'inscrit dans ce débat sur le fédéralisme et propose une contribution originale en termes de mise à l'agenda des politiques publiques. Il soutient que les deux perspectives sont nécessaires à la compréhension de la dynamique de l'élaboration des politiques au sein des systèmes fédéraux. En mesurant le changement de l'attention politique dans les discours du Trône canadiens et britanniques, l'article affirme que le fédéralisme freine le changement de politique immédiatement après un changement de parti au gouvernement. Au cours d'une législature, toutefois, les institutions fédérales encouragent de plus grands changements dans l'attention des politiques que dans des systèmes unitaires où le pouvoir est centralisé.
Must We All Be Paradigmatic? Social Investment Policies and Liberal Welfare States
Authors: White Linda A. 
Published: November 2012

Abstract.This article examines whether current shifts in government spending on early childhood education and care (ECEC) and maternal employment-promoting policies such as maternity and parental leave reveal a paradigm shift toward a social investment strategy in liberal welfare states. It finds that while governments in liberal welfare states increasingly adhere to the rhetoric of social investment focused on lifelong learning and labour activation, their policies and programs exhibit so much variation in goals, instruments and settings related to the family, maternal employment and the child that it is difficult to claim that any new policy approach has taken hold that is indicative of a social investment “paradigm.” Instead, liberal welfare states appear to be becoming even more liberal—in terms of reliance on markets for delivery of social investment goals—at the same time as spending is increasing.Résumé.Cet article examine si les changements actuels des dépenses de gouvernement sur la première éducation d'enfance et le soin (ECEC) et les politiques promouvant emploi maternelles comme la maternité et le congé parental révèlent un changement de paradigme vers une stratégie sociale d'investissement dans les Etats-providences libéraux. Il constate que pendant que les gouvernements dans les Etats-providences libéraux adhèrent de plus en plus à la rhétorique d'investissement social s'est concentré sur l'apprentissage de toute une vie et l'activation de la main-d'œuvre, leurs politiques et programmes exposent tant de variation dans les buts, les instruments et les cadres rattachés à la famille, l'emploi maternel et l'enfant qu'il est difficile de réclamer que n'importe quelle nouvelle approche de politique a attrapé qui est indicatif “d'un paradigme” social d'investissement. Au lieu de cela les Etats-providences libéraux ont l'air de devenir encore plus libéraux – du point de vue de la dépendance aux marchés pour la livraison de buts sociaux d'investissement – en même temps comme les dépenses augmentent.
Enquête sur le rapport des journalistes à la démocratie : le rôle de médiateur en question
Authors: Gingras Anne-Marie 
Published: November 2012

Résumé.Dans ce texte, nous tentons d'évaluer le rôle sociopolitique des journalistes en posant les éléments fondamentaux d'une conceptualisation du rôle des médias en démocratie et en analysant les résultats d'une recherche empirique sur l'engagement des journalistes envers la démocratie menée de l'été 2008 au printemps 2010. Notre étude prend appui sur la dichotomie entre un rôle actif des médias et un rôle instrumental face au système politique, dichotomie que nous faisons porter sur les journalistes. Nous prétendons que les médias et les journalistes jouent le rôle de « médiateurs » dans les sociétés libérales, c'est-à-dire d'agents individuels ou collectifs par qui transitent des messages explicites ou implicites; ces agents ajoutent une couche de sens par diverses méthodes dont la sélection des nouvelles, la hiérarchisation des sujets ou le cadrage de personnes ou d'événements.Abstract.This paper aims to assess the sociopolitical role of journalists through a conceptual approach linking media and democracy and through an analysis of the data resulting from an investigation of journalists' commitment to democracy that was conducted from the summer of 2008 to the spring of 2010. Our study is founded on the dichotomy between an active role for the media and an instrumental one in the face of the political system, and this dichotomy is applied to journalists. We believe that the media and journalists function as “mediators” in liberal societies, that is, as individual or collective agents through whom explicit or implicit messages pass; these agents add a layer of signification by diverse methods, among which are the selection of news, the categorization of issues or the framing of individuals or events.
SUEZ AND BRITAIN'S DECLINE AS A WORLD POWER
Authors: PEDEN G. C. 
Published: November 2012

ABSTRACTThe Suez crisis is widely believed to have contributed significantly to Britain's decline as a world power. Eden's miscalculation of American reaction to the attack on Egypt was damaging to Britain's reputation and fatal to his career. However, his actions were contrary to received wisdom in Whitehall. The crisis merely confirmed Britain's dependence on the United States and had no lasting impact on Anglo-American relations. Britain's relationship with its informal and formal empire was already changing before 1956, and the turn from the commonwealth to Europe owed little to Suez. Examination of policy reviews in Whitehall before and after the Suez crisis shows that the Foreign Office, Commonwealth Relations Office, and Colonial Office were slow to accept the need for change in Britain's world role. Insofar as they did from 1959 it was because of Treasury arguments about the effect of high defence expenditure on the economy, and slow growth of the United Kingdom's population compared with the United States, the European Economic Community, and the Soviet Union.
UNDERWRITING BRITISH TRADE TO INDIA AND CHINA, 1780–1835
Authors: LEONARD A. B. 
Published: November 2012

ABSTRACTIn the late eighteenth century, European merchants launched corporate insurance bodies in India and China. These new joint-stock companies followed London's mature and efficient institutional systems for marine insurance, and adopted their basis in the European law merchant. They operated alongside local risk transfer facilities, but in both countries were quickly embraced by native merchants, who participated both as customers and shareholders. The rapid development of a corporate insurance sector in India and China, fuelled by the capital of local merchants and members of the European colonial elite, underlines the effectiveness of premium-based marine insurance, while its swift adoption by both local and international merchants shows its importance to the development of trade and empire.
The prediction of live weight from body measurements on female Holstein calves by digital image analysis
Authors: OZKAYA S. 
Published: November 2012

SUMMARYThe objective of the current study was to determine the accuracy of the prediction of live weight (LW) from body measurements (BMs) by using digital image analysis on female Holstein calves. The calves were measured with a measurement stick and digital image analysis. The following linear parameters were taken: body length (BL), wither height (WH), chest depth (CD), hip height (HH) and hip width (HW). LW and BMs were recorded at birth, at weaning and at 24 weeks of age. Regression coefficients, which included all BMs at birth, gave a low R2 value (66·7%), but the R2 value was found to be 87·6 and 86·0% at weaning and 24 weeks of age, respectively. A high correlation coefficient was found among LW and CD, HH and HW at weaning (0·90, 0·91 and 090, respectively) and at 24 weeks of age (0·89, 0·90 and 0·91, respectively). The results confirm that for female Holstein calves, digital image analysis is an effective measuring system for the prediction of LW from BMs.
TESTING EVOLUTIONARY THEORIES OF DISCRIMINATIVE GRANDPARENTAL INVESTMENT
Authors: KAPTIJN RALF , THOMESE FLEUR , LIEFBROER AART C. , SILVERSTEIN MERRIL 
Published: November 2012

SummaryThis study tests two evolutionary hypotheses on grandparental investments differentiated by the child's sex: the paternity uncertainty hypothesis and the Trivers–Willard hypothesis. Data are from two culturally different countries: the Dutch Longitudinal Aging Study Amsterdam (n=2375) and the Chinese Anhui Survey (n=4026). In the Netherlands, grandparental investments are biased towards daughters' children, which is in accordance with the paternity uncertainty hypothesis. But in China, grandparental investments are biased towards sons' children, which is in conflict with the paternity uncertainty hypothesis. This study found no support for the Trivers–Willard hypothesis. These results raise doubts over the relevance of paternity uncertainty as an explanation of a grandparental investment bias towards daughters' children that is often found in Western populations. The results suggest that discriminative grandparental investments are better understood as the outcome of cultural prescriptions and economic motives.
PREVALENCE OF CONSANGUINEOUS MARRIAGES IN WEST AND SOUTH OF AFGHANISTAN

Published: November 2012

SummaryThe prevalence of consanguinity in eight provinces of Afghanistan has recently been reported by Saify & Saadat (2012). The present cross-sectional study was done in order to illustrate the prevalence and types of consanguineous marriages among other populations of Afghanistan. Data on types of marriages were collected using a simple questionnaire. The total number of couples in this study was 5200 from the following provinces: Farah, Ghazni, Herat, Hilmand, Kabul, Kandahar, Logar, Parwan and Wardak. Consanguineous marriages were classified by the degree of relationship between couples: double first cousins, first cousins, first cousins once removed, second cousins and beyond second cousins. The coefficient of inbreeding (F) was calculated for each couple and the mean coefficient of inbreeding (α) estimated for each population. The α in the country was 0.0226, ranging from 0.0203 in Farah province to 0.0246 in Herat province. There were significant differences between provinces for frequencies of different types of marriages (p<0.001). First cousin marriages (21.7%) were the most common type of consanguineous marriages, followed by second cousins (16.0%), first cousins once removed (14.0%), beyond second cousins (6.9%) and double first cousins (1.6%). There was significant difference between ethnic groups for the types of marriages (p<0.001). Tajiks (Soni) and Sadats showed the lowest (α=0.0215) and highest (α=0.0242) levels of consanguinity among ethnic groups in Afghanistan, respectively. The present study shows that the Afghani populations, the same as other Islamic populations, have high levels of consanguinity.
Affective Decision-Making on the Iowa Gambling Task in Children and Adolescents with Fetal Alcohol Spectrum Disorders

Published: November 2012

AbstractIndividuals with fetal alcohol spectrum disorders (FASD) have difficulties with cognitive-based executive function (EF) tasks. The goal of the present study was to determine if children with FASD have impairments on the Iowa Gambling Task (IGT), which measures affective EF (i.e., decision-making and risk-taking). Individuals with FASD (n = 31) and healthy controls (n = 31), aged 8–17 completed the IGT. Children with FASD were significantly impaired on the IGT compared to controls. Over the course of the task, control scores improved, whereas children with FASD exhibited an overall decrease in scores. Scores increased significantly with age in the control group but did not differ significantly with age for FASD participants. Children with FASD exhibited decision-making and risk-taking impairments on a hot EF task. Children with FASD did not appear to learn from negative experiences and shift to making more positive decisions over time and their performance did not improve with age. The implications of poor task performance and a lack of age-related findings in children with FASD are discussed. (JINS, 2012, 18, 1–8)
NUMERICAL SIMULATION OF ATHEROSCLEROTIC PLAQUE GROWTH USING TWO-WAY FLUID–STRUCTURAL INTERACTION
Authors: CHEN C. X. , DING Y. , GEAR J. A. 
Published: November 2012

AbstractThis paper presents a numerical investigation of plaque growth in a diseased artery using the two-way fluid–structural interaction (FSI) technique. An axis-asymmetric 45% stenosis model is used as the base model to start the plaque growth approximation. The blood is modelled as a non-Newtonian fluid described by the Casson model. The artery tissue is assumed to be a nonlinear material. The two-way FSI simulation is carried out in a way that mimics the unsteady blood flow through a diseased artery by using a pulsatile flow condition. After each flow velocity cycle, the numerical results are extracted and used to modify the stenosis geometry based upon critical wall shear stress (WSS) values and an accepted relationship between the concentration of low density lipoprotein and WSS. The simulation procedure is repeated until the growth-updated stenosis morphology reaches 79% severity. The behaviour of the flow velocity is analysed at each growth stage, together with the WSS, to determine the change of plaque morphology due to growth. The effects of WSS and pressure on the artery wall at the final stage (79% severity) of the plaque growth model are also compared with results from the authors’ previous work, to demonstrate the importance of the morphology change in plaque growth modelling.
“Whitening” and the Changing American Racial Hierarchy
Authors: Gans Herbert J. 
Published: November 2012

AbstractAs a result of the increasing number of biracials and multiracials, and White reconstructions of previously non-White skin colors, the Whitening of selected immigrants and especially their children appears to be proceeding. Although there are many studies on the racial identity of biracials, too little research exists on how Whites identify them and light-skinned monoracials, which of these they Whiten, how, and why. Enough is known to suggest that if current trends continue, our picture of the country's racial hierarchy has to be revised. While Whites will likely remain on top and poor African Americans and other Blacks at the bottom, what happens in the middle cannot now even be guessed at with any hope of accuracy. For that reason alone, empirical and policy-oriented research on White identification patterns is badly needed.
A novel technique for rapid L* calculation using UBK coordinates
Authors: Min Kyungguk , Bortnik Jacob , Lee Jeongwoo 
Published: November 2012

AbstractThe magnetic drift invariant (L*) is an important quantity used for tracking and organizing particle dynamics in the radiation belts, but its accurate calculation has been computationally expensive in the past, thus making it difficult to employ this quantity in real‐time space weather applications. In this paper, we propose a new, efficient method to calculate L* using the principle of energy conservation. This method uses Whipple's (U, B, K) coordinates to quickly and accurately determine trajectories of particles at the magnetic mirror point from two‐dimensional isoenergy contours. The method works for any magnetic field configuration and is able to accommodate constant electric potential along field lines. We compare the result of this method with those of International Radiation Belt Environment Modeling library (IRBEM‐LIB) to demonstrate the performance of this new method. The method requires a preparation step, and thus may not be the optimal method for a single trajectory calculation; however, it presents a huge performance gain when adiabatically propagating a large population of particles in a given magnetic field configuration.
Rupture directivity of small earthquakes at Parkfield

Published: November 2012

AbstractTheoretical modeling of strike‐slip ruptures along a bimaterial interface suggests that earthquakes initiating on the interface will have a preferred rupture direction. We test this model with 450 small earthquakes (2 < M < 5) from Parkfield, California, to look for evidence of consistent rupture directivity along the San Andreas Fault. We analyze azimuthal variations in earthquake source spectra after applying an iterative correction for wave propagation effects. Our approach avoids directly modeling source spectra because these models generally assume symmetric rupture; instead, we look for azimuthal variations in the amplitudes of the source spectra over specified frequency bands. Our overall results show similar proportions of events exhibiting characteristics of rupture directivity toward either the southeast or northwest. However, the proportion of events with southeast rupture directivity increases as we limit the data set to larger magnitudes, with 70% of the 46 events M > 3 exhibiting southeast rupture characteristics. Some spatial and temporal variability in rupture directivity is also apparent. We observe a higher proportion of northwest directivity ruptures following the 2004 M 6 Parkfield earthquake, which ruptured toward the northwest. Our results are generally consistent with the preferred southeast rupture directivity model but suggest that directivity is likely due to several contributing factors.
