Rhizomatic Explorations in Curriculum

A visual and theatrical exercise anchored in the Grades 11 and 12 Ontario Curriculum for Media Arts and Interdisciplinary Studies was enacted and recorded as individual experiences of each participant. The event was re-mastered in a graphic representation that depicts the forces, pushes and pulls of curriculum and students’ needs which educators experience on a daily basis. Students participating in a co-educational public high school course were photographed alongside their yearbook advisor to examine the methodology of a/r/tography, embodiment and time/space/place during a staged photo shoot session. Participants, including the author, documented their experiences of this research creation event through written and photographic feedback. The basic findings resulted in the creation of the Dimension of the Mind Embodied (DOME), a new theory I coined that builds on Deleuze and Guattari’s (1987) concept of the rhizome. Chaque participant à un programme d'études en arts des médias et études interdisciplinaires de l'Ontario pour les 11e et 12e années a interprété un exercice visuel et théâtral. L'évènement a été remasterisé en une représentation graphique illustrant tant les forces et les mouvements en opposition du programme d'études que les besoins des élèves auxquels font face les enseignants à chaque jour. On a photographié des élèves qui suivaient un cours dans une école secondaire publique mixte à côté d'un conseiller de sorte à étudier l'a/r/tographie, la concrétisation et le temps/l'espace/le lieu pendant une session de photos publique. Les participants, y compris l'auteur, ont documenté leurs expériences relatives à cet évènement de création en produisant de la rétroaction écrite et photographique. De ces résultats a découlé la création de Dimension of the Mind Embodied (DOME), une nouvelle théorie que j'ai inventée à partir du concept de rhizome de Deleuze et Guattari (1987)

Large Magellanic Cloud Near-Infrared Synoptic Survey. I. Cepheid variables and the calibration of the Leavitt Law

We present observational details and first results of a near-infrared (JHKs) synoptic survey of the central region of the Large Magellanic Cloud using the CPAPIR camera at the CTIO 1.5-m telescope. We covered 18 sq. deg. to a depth of Ks~16.5 mag and obtained an average of 16 epochs in each band at any given location. Our catalog contains more than 3.5x10^6 sources, including 1417 Cepheid variables previously studied at optical wavelengths by the OGLE survey. Our sample of fundamental-mode pulsators represents a 9-fold increase in the number of these variables with time-resolved, multi-band near-infrared photometry. We combine our large Cepheid sample and a recent precise determination of the distance to the LMC to derive a robust absolute calibration of the near-infrared Leavitt Law for fundamental-mode and first-overtone Cepheids with 10x better constraints on the slopes relative to previous work. We also obtain calibrations for the Tip of the Red Giant Branch and the Red Clump based on our ensemble photometry which are in good agreement with previous determinations.Comment: v3 contains small changes to the published results (~0.04, 0.025, 0.017 mag in JHKs, respectively) arising from a correction to the values of total-to-selective absorption.

A mutation in the PA protein gene of cold-adapted B/Ann Arbor/1/66 influenza virus associated with reversion of temperature sensitivity and attenuated virulence

Reassortant SG3 inherits only the acidic polymerase (PA) protein gene from the cold-adapted B/AA/1/66 influenza virus (ca B/AA/l/66) and all remaining genes from a virulent, wild-type virus. This reassortant demonstrates attenuated virulence in ferrets and expresses a is phenotype characteristic of the ca parent. During virulence evaluation of SG3, a virulent, non-ts revertant virus (designated SG3rFL) was isolated from the lungs of one ferret. In order to determine whether the reversion of SG3 resulted from mutation of the PA gene and/or as the result of extragenic supressor mutations, the revertant PA gene of SG3rFL was transferred to a reassortant (SG3r) inheriting only the revertant PA gene from SG3rFL and all remaining genes from SG3. Reassortant SG3r was non-ts and virulent, indicating that mutation of the PA gene was sufficient for the reversion of the is and attenuation phenotypes expressed by SG3rFL. The nucleotide and predicted amino acid sequences of the SG3rFL PA gene were determined and compared to those of wt and ca B/AA/1 /66. The predicted PA proteins of wt and ca B/AA/1 /66 are known to differ by six amino acid substitutions including a valine to methionine substitution at residue 431. The PA proteins of ca B/AA/1/66 and SG3rFL were distinguished by only the single amino acid substitution of methionine to isoluecine also occurring at residue 431. Thus, the methionine residue was implicated in the attenuation of ca B/AA/1/66 and its reassortants. The hydropathic properties of valine, isoleucine, and methionine suggested that reversion involved the restoration of hydrophobic character at this site.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27363/1/0000388.pd

The Japanese model in retrospective : industrial strategies, corporate Japan and the 'hollowing out' of Japanese industry

This article provides a retrospective look at the Japanese model of industrial development. This model combined an institutional approach to production based around the Japanese Firm (Aoki's, J-mode) and strategic state intervention in industry by the Japanese Ministry of International Trade and Industry (MITI). For a long period, the alignment of state and corporate interests appeared to match the wider public interest as the Japanese economy prospered. However, since the early 1990s, the global ambitions of the corporate sector have contributed to a significant 'hollowing out' of Japan's industrial base. As the world today looks for a new direction in economic management, we suggest the Japanese model provides policy-makers with a salutary lesson in tying the wider public interest with those of the corporate sector

Trade in the Shadow of Power : Japanese Industrial Exports in the Interwar years

During the interwar years, Japanese industrialisation accelerated alongside the expansion of industrial exports to regional markets. Trade blocs in the interwar years were used as an instrument of imperial power to foster exports and as a substitute for productivity to encourage industrial production. The historiography on Japanese industrialisation in the interwar years describes heavy industries' interests in obtaining access to wider markets to increase economies of scale and reduce unit costs. However, this literature provides no quantitative evidence that proves the success of those mechanisms in expanding exports. In this paper we scrutinise how Japan—a relatively poor country—used colonial as well as informal power interventions to expand regional markets for its exports, especially for the most intensive human capital sector of the industrializing economy

LPIN1 gene mutations: a major cause of severe rhabdomyolysis in early childhood.

International audienceAutosomal recessive LPIN1 mutations have been recently described as a novel cause of rhabdomyolysis in a few families. The purpose of the study was to evaluate the prevalence of LPIN1 mutations in patients exhibiting severe episodes of rhabdomyolysis in infancy. After exclusion of primary fatty acid oxidation disorders, LPIN1 coding sequence was determined in genomic DNA and cDNA. Among the 29 patients studied, 17 (59%) carried recessive nonsense or frameshift mutations, or a large scale intragenic deletion. In these 17 patients, episodes of rhabdomyolysis occurred at a mean age of 21 months. Secondary defect of mitochondrial fatty oxidation or respiratory chain was found in skeletal muscle of two patients. The intragenic deletion, c.2295-866_2410-30del, was identified in 8/17 patients (47%), all Caucasians, and occurred on the background of a common haplotype, suggesting a founder effect. This deleted human LPIN1 form was unable to complement ∆pah1 yeast for growth on glycerol, in contrast to normal LPIN1. Since more than 50% of our series harboured LPIN1 mutations, LPIN1 should be regarded as a major cause of severe myoglobinuria in early childhood. The high frequency of the intragenic LPIN1 deletion should provide a valuable criterion for fast diagnosis, prior to muscle biopsy

The question of access to the Japanese market

This survey focuses on the question of how market structure and different corporate organisational forms might affect access to the Japanese market for industrial goods. The question is how and whether keiretsu corporate structures in Japan constitute an important unofficial barrier in access to the Japanese market for manufactured goods

Overlapping SETBP1 gain-of-function mutations in Schinzel-Giedion syndrome and hematologic malignancies

Schinzel-Giedion syndrome (SGS) is a rare developmental disorder characterized by multiple malformations, severe neurological alterations and increased risk of malignancy. SGS is caused by de novo germline mutations clustering to a 12bp hotspot in exon 4 of SETBP1. Mutations in this hotspot disrupt a degron, a signal for the regulation of protein degradation, and lead to the accumulation of SETBP1 protein. Overlapping SETBP1 hotspot mutations have been observed recurrently as somatic events in leukemia. We collected clinical information of 47 SGS patients (including 26 novel cases) with germline SETBP1 mutations and of four individuals with a milder phenotype caused by de novo germline mutations adjacent to the SETBP1 hotspot. Different mutations within and around the SETBP1 hotspot have varying effects on SETBP1 stability and protein levels in vitro and in in silico modeling. Substitutions in SETBP1 residue I871 result in a weak increase in protein levels and mutations affecting this residue are significantly more frequent in SGS than in leukemia. On the other hand, substitutions in residue D868 lead to the largest increase in protein levels. Individuals with germline mutations affecting D868 have enhanced cell proliferation in vitro and higher incidence of cancer compared to patients with other germline SETBP1 mutations. Our findings substantiate that, despite their overlap, somatic SETBP1 mutations driving malignancy are more disruptive to the degron than germline SETBP1 mutations causing SGS. Additionally, this suggests that the functional threshold for the development of cancer driven by the disruption of the SETBP1 degron is higher than for the alteration in prenatal development in SGS. Drawing on previous studies of somatic SETBP1 mutations in leukemia, our results reveal a genotype-phenotype correlation in germline SETBP1 mutations spanning a molecular, cellular and clinical phenotype

Identification of the Rostral Migratory Stream in the Canine and Feline Brain

In the adult rodent brain, neural progenitor cells migrate from the subventricular zone of the lateral ventricle towards the olfactory bulb in a track known as the rostral migratory stream (RMS). To facilitate the study of neural progenitor cells and stem cell therapy in large animal models of CNS disease, we now report the location and characteristics of the normal canine and feline RMS. The RMS was found in Nissl-stained sagittal sections of adult canine and feline brains as a prominent, dense, continuous cellular track beginning at the base of the anterior horn of the lateral ventricle, curving around the head of the caudate nucleus and continuing laterally and ventrally to the olfactory peduncle before entering the olfactory tract and bulb. To determine if cells in the RMS were proliferating, the thymidine analog 5-bromo-2-deoxyuridine (BrdU) was administered and detected by immunostaining. BrdU-immunoreactive cells were present throughout this track. The RMS was also immunoreactive for markers of proliferating cells, progenitor cells and immature neurons (Ki-67 and doublecortin), but not for NeuN, a marker of mature neurons. Luxol fast blue and CNPase staining indicated that myelin is closely apposed to the RMS along much of its length and may provide guidance cues for the migrating cells. Identification and characterization of the RMS in canine and feline brain will facilitate studies of neural progenitor cell biology and migration in large animal models of neurologic disease
