RNA Interference of MDR Genes in Leptinotarsa decemlineata and Trichoplusia ni by Ingestion of Double-Stranded RNA
Insecticide resistance is often linked to the expression of detoxification genes such as MDRs which code for ATP-binding cassette efflux transporters with broad substrate specificity. To investigate the role of MDR genes in Leptinotarsa decemlineata and Trichoplusia ni tolerance for the insecticide ivermectin, ingested dsRNA was used to attempt silencing of various MDR genes in these insects through RNA interference. Silencing was effective in L. decemlineata, but not T. ni. No change in ivermectin tolerance was found in L. decemlineata after MDR gene silencing. Because RNAi efficiency was different between L. decemlineata and T. ni, the stability of dsRNA in midgut lumen and hemolymph was compared between the two species and another insect, Manduca sexta. The dsRNA was least stable in T. ni body fluids, providing a likely cause for the ineffectiveness of ingested dsRNA
The Effects Upon Students of Supplementing Aboriginal Post-Secondary Transition Programs With Traditional Cultural Activities
THE EFFECTS UPON STUDENTS OF SUPPLEMENTING ABORIGINAL POST-SECONDARY TRANSITION PROGRAMS WITH TRADITIONAL CULTURAL ACTIVITIES

ABSTRACT
This study investigates Aboriginal student experiences in an Aboriginal transition program that was co-developed by the student-participants. Data was collected from participants in the study through a focus group, journals, and surveys. The results show that adding Aboriginal cultural activities to the curriculum improved the experience of students in the transition program. Students felt that their contributions were important and valued, that they learned more about their traditional culture, and that their contributions enhanced their experience in the program. Allowing Aboriginal students to participate in their own education empowers them and improves their overall educational experience.

Visions of Tokyo in Japanese Contemporary Art
So many foreigners âexperienceâ tokyo for the first time through the incandescent images of anime movies or the startling pages of cult manga. It is no surprise, then, that visions of Tokyo taken from Japanese contemporary art have been filtered significantly by Japanâs most internationally visible forms of pop culture.1 This, of course, was the strategy adopted with success by Japanâs most famous contemporary artist, Murakami Takashi (b. 1962), as curator and featured artist in his landmark touring shows âSuperflatâ and âLittle Boy.â2 Many Western curators and art publishers have lined up to reproduce this selective vision of contemporary art in Japan.3 (...)
Rebooting migration theory: Interdisciplinarity, globality and postdisciplinarity in migration studies
It is no small ambition to bring together a comprehensive overview of contemporary migration theory across the social sciences and humanities. Such has been the explosion of interest in international migration in the past decade or so that no scholar nowadays can feel adequate when confronting the avalanche of literature that has followed. The rather heroic enterprise presented here has the virtue of letting disciplinary perspectives speak for themselves in a congenial dialogue, rather than attempting a unified theory, the most prominent of which have typically emerged from a base in economic theory (Massey et al. 1998; Hammar et al. 1997). It is thus highly instructive to read each chapter as a guide to the specific mindset of various disciplines toward the subject. Nonspecialists will learn as much about what political scientists, anthropologists, demographers, economists, or lawyers do from reading the respective
chapters, as about political science, anthropological, demographic, economic, or legal approaches to migration theory (...)
Compared to its neighbours, open migration to Britain has been a success story
Eastern European migration to the UK is deplored by many Britons. Yet, argues Adrian Favell, comparing Britainâs experience with that of other member states shows just how well it has done out of freedom of movement. The UK has a flexible, well-educated migrant workforce at its disposal â unlike other countries, some of which have lost qualified workers or are struggling to deal with inflows from outside the EU
Tokyo to LA story: how Southern California became the gateway for a Japanese global pop art phenomenon
An analysis of the demographic and geographic conditions that have enabled Los Angeles (LA) to become a gateway for imports of Japanese contemporary cultures in the West, illustrated with the case of Japanese contemporary art, and the international success stories of Takashi Murakami and Yoshitomo Nara (...)
The UK has been one of the main beneficiaries from free movement of labour in the EU
Free movement of labour across the EU has become a controversial issue in several European countries, with parties such as UKIP and the Front National calling for restrictions on EU immigration. Adrian Favell writes on the debate over the issue within the UK. He argues that while free movement has generally been portrayed as an âimmigrationâ problem, it should instead be viewed as a set of rights which allow a range of short-term and long-term movements within the EU. He also notes that the UK economy has been particularly well placed to benefit from free movement, with cities like London being among the most attractive destinations for highly skilled workers
The struggle for a page in art history: the global and national ambitions of Japanese contemporary artists from the 1990s'
Although an undifferentiated notion of âglobal artâ in the 1990s and 2000s became the dominant reference point for the evaluation of artistsâ careers (Stallabrass 2004, Thornton 2008), it is striking how much a national reference still matters to the generation who emerged as the first wave of properly globalised Japanese contemporary art in the late 80s/early 90s. Even the most globally successful of all, Takashi Murakami, in the end apparently only really cares about securing his page in the Japanese art history textbooks. It is also striking how as yet undecided this struggle is from the point of view of Japanese art history and art criticism. With mention of six key mid-career male artists now at the height of their powers and each with a claim to this prize -- Murakami (b.1962), Yoshitomo Nara (b.1959), Masato Nakamura (b.1963), Yukinori Yanagi (b.1959), Makoto Aida (b.1965) and Tsuyoshi Ozawa (b.1965) -- I will compare and contrast the different role that internationalisation has played in their careers. Each of them has âgone homeâ in one way another, and each is creating his own âschoolâ. Will there continue to be the need, as Murakami has repeatedly argued in his writings, for the classic strategy of international mobility plus gaisen koen (âtriumphant return performanceâ), to etch their name in history? Or will this prove in fact to be Murakamiâs biggest liability? Will market evaluation, curatorial discourse, critical prestige, academic influence, museum popularity, or social/community impact decide the contest? And how much of this art historical struggle is still contained within the internal national art system, and how much of it is truly global (or regional) in its dynamics
The Changing Face of âIntegrationâ in a Mobile Europe
Amidst the rising tide of anti-immigration across all of Europe â which now includes Eastern and Southern
Europeans as much as familiar targets such as Muslims or undocumented Africans â there has been little
questioning of the dominant mainstream progressive response to the consequences of migration: that
âintegrationâ is the best and most realistic solution for nations now having to accommodate the populations
who have moved into or around Europe during the past two highly mobile decades of the 1990s and 2000s (...)
Visions of Neo-TĂŽkyĂŽ:Culture pop dans l'art contemporain japonais
La plupart des étrangers découvrent TÎkyÎ pour la premiÚre fois dans les images colorées des anime,
ou dans les Ă©tonnantes pages des manga. Il nâest alors pas surprenant que beaucoup des reprĂ©sentations
de TĂŽkyĂŽ dans lâart contemporain japonais empruntent aux formes les plus visibles de la culture populaire japonaise. Câest Ă©videmment la stratĂ©gie adoptĂ©e avec succĂšs par lâartiste contemporain japonais le plus connu, Takashi Murakami, Ă la fois curateur et artiste pour ses expositions Superflat et Little Boy. Câest aussi la tendance quâont suivie de nombreux commissaires dâexposition et Ă©diteurs de livres dâart occidentaux en reproduisant cette vision sĂ©lective de lâart contemporain japonais
