Neo-Liberalism, NAFTA, and the State of the North American Labour Movements

The consolidation of neo-liberalism since the 1980s has presented several challenges to unions in North America. Through the restructuring of the state and the promotion of globalization, neo-liberalism has made the terrain of struggle more daunting for unions. Changes in the organization of work are also implicated in the common threats to organized labour and workers more generally. These common pressures on labour in Canada, the United States and Mexico, however, have resulted in different outcomes for the three movements. Many have suggested that these common pressures should be met with an increased emphasis on transnational labour cooperation. It is argued here it is possible to build international solidarity without first building union capacities at the level of the local plant and at the level of the nation state

Expanded Use of AVL/GPS Technology: Final Report

MnDOT Contract No. 1044528Summer road maintenance is a critical activity for highway maintenance agencies that involves a wide range of maintenance and construction vehicles that can be active at any given time, which makes vehicle and maintenance asset management challenges. Automated Vehicle Location (AVL) and Global Positioning Systems (GPS) technologies installed in winter maintenance vehicles have the potential to support summer road maintenance vehicles to improve asset tracking and management practices, as well as other purposes such as process automation and paperwork reduction for field staff in terms of activity reporting. The use of AVL/GPS systems to support both winter and summer maintenance activities can help justify the expenses incurred with respect to hardware / software acquisition and training costs across a wide range of applications. This report continues building upon prior Clear Roads research and helps highway maintenance agencies optimize the value gained from the acquisition of AVL/GPS systems by deploying them year-round, rather than being limited to winter maintenance operations. This report summarizes agencies\u2019 experiences and lessons learned in using AVL/GPS technologies in summer and year-round maintenance activities. It also highlights the types of issues other highway maintenance agencies should consider prior to system procurement, provides guidance for successful transition and implementation of the technology, and serves as a possible template for agencies to get the best value out of different levels their AVL/GPS applications

Project Re•center dot Vision: disability at the edges of representation

The representational history of disabled people can largely be characterized as one of being put on display or hidden away. Self-representations have been a powerful part of the disability rights and culture movement, but recently scholars have analysed the ways in which these run the risk of creating a ‘single story’ that centres the experiences of white, western, physically disabled men. Here we introduce and theorize with Project Re•Vision, our arts-based research project that resists this singularity by creating and centring, without normalizing, representations that have previously been relegated to the margins. We draw from body becoming and new materialist theory to explore the dynamic ways in which positionality illuminates bodies of difference and open into a discussion about what is at stake when these stories are let loose into the world

Creative learning environments in education-A systematic literature review

This paper reports on a systematic review of 210 pieces of educational research, policy and professional literature relating to creative environments for learning in schools, commissioned by Learning and Teaching Scotland (LTS). Despite the volume of academic literature in this field, the team of six reviewers found comparatively few empirical studies published in the period 2005–2011 providing findings addressing the review objectives. There was, however a reasonable weight of research evidence to support the importance of the following factors in supporting creative skills development in children and young people: flexible use of space and time; availability of appropriate materials; working outside the classroom/school; ‘playful’ or ‘games-bases’ approaches with a degree of learner autonomy; respectful relationships between teachers and learners; opportunities for peer collaboration; partnerships with outside agencies; awareness of learners’ needs; and non-prescriptive planning. The review also found evidence for impact of creative environments on pupil attainment and the development of teacher professionalism. LTS intend to use the review as a basis for recommendations to Scottish schools in promoting creativity within Curriculum for Excellence. However, the findings of the review and methodological gaps in the reviewed studies have implications for policy, practice and research internationally

A Population Genetic Approach to Mapping Neurological Disorder Genes Using Deep Resequencing

Deep resequencing of functional regions in human genomes is key to identifying potentially causal rare variants for complex disorders. Here, we present the results from a large-sample resequencing (n = 285 patients) study of candidate genes coupled with population genetics and statistical methods to identify rare variants associated with Autism Spectrum Disorder and Schizophrenia. Three genes, MAP1A, GRIN2B, and CACNA1F, were consistently identified by different methods as having significant excess of rare missense mutations in either one or both disease cohorts. In a broader context, we also found that the overall site frequency spectrum of variation in these cases is best explained by population models of both selection and complex demography rather than neutral models or models accounting for complex demography alone. Mutations in the three disease-associated genes explained much of the difference in the overall site frequency spectrum among the cases versus controls. This study demonstrates that genes associated with complex disorders can be mapped using resequencing and analytical methods with sample sizes far smaller than those required by genome-wide association studies. Additionally, our findings support the hypothesis that rare mutations account for a proportion of the phenotypic variance of these complex disorders

Critical psychologies of disability: boundaries, borders and bodies in the lives of disabled children

Attending to the ways in which bodies and subjectivities are constituted in social environments is not simply a concern of social geographers but an emerging interest in critical psychology, childhood and disability studies. Boundaries and borders are nothing if not the different relational and durational articulations of bodies and spaces. These entangled boundaries include borders between parent and child; culture and body; school, family and child. Through analysing the ways in which these borderlines are continually re-composed and re-constituted, we are able to reveal their relational and embodied articulations. In previous works, we have explored the ways in which disabled children disrupt normative orders associated with school, family and community. In this paper, we take up the concepts of boundaries and borders to explore their relational and embodied articulations with specific reference to stories collected as part of an ESRC project entitled ‘Does every child matter, Post-Blair: the interconnections of disabled childhoods’. We ask, how do disabled children negotiate space in their lives? In what ways do they challenge space through their borders and boundaries with others? How can we re-imagine, re-think and differently practice – that is revolutionise – key borders and boundaries of education in ways that affirm the lives of disabled children? We address these questions through reference to the narrative from the Derbyshire family, with particular focus on Hannah and her mother Linda, which we argue allow us to consider the ways in which disabled childhoods can be understood and reimagined. We explore two analytical considerations; ‘Being disabled: being mugged’ and ‘Becoming enabled: teacups, saucers and communities’

Antioxidant Protects against Increases in Low Molecular Weight Hyaluronan and Inflammation in Asphyxiated Newborn Pigs Resuscitated with 100% Oxygen

BACKGROUND: Newborn resuscitation with 100% oxygen is associated with oxidative-nitrative stresses and inflammation. The mechanisms are unclear. Hyaluronan (HA) is fragmented to low molecular weight (LMW) by oxidative-nitrative stresses and can promote inflammation. We examined the effects of 100% oxygen resuscitation and treatment with the antioxidant, N-acetylcysteine (NAC), on lung 3-nitrotyrosine (3-NT), LMW HA, inflammation, TNFα and IL1ß in a newborn pig model of resuscitation. METHODS & PRINCIPAL FINDINGS: Newborn pigs (n = 40) were subjected to severe asphyxia, followed by 30 min ventilation with either 21% or 100% oxygen, and were observed for the subsequent 150 minutes in 21% oxygen. One 100% oxygen group was treated with NAC. Serum, bronchoalveolar lavage (BAL), lung sections, and lung tissue were obtained. Asphyxia resulted in profound hypoxia, hypercarbia and metabolic acidosis. In controls, HA staining was in airway subepithelial matrix and no 3-NT staining was seen. At the end of asphyxia, lavage HA decreased, whereas serum HA increased. At 150 minutes after resuscitation, exposure to 100% oxygen was associated with significantly higher BAL HA, increased 3NT staining, and increased fragmentation of lung HA. Lung neutrophil and macrophage contents, and serum TNFα and IL1ß were higher in animals with LMW than those with HMW HA in the lung. Treatment of 100% oxygen animals with NAC blocked nitrative stress, preserved HMW HA, and decreased inflammation. In vitro, peroxynitrite was able to fragment HA, and macrophages stimulated with LMW HA increased TNFα and IL1ß expression. CONCLUSIONS & SIGNIFICANCE: Compared to 21%, resuscitation with 100% oxygen resulted in increased peroxynitrite, fragmentation of HA, inflammation, as well as TNFα and IL1ß expression. Antioxidant treatment prevented the expression of peroxynitrite, the degradation of HA, and also blocked increases in inflammation and inflammatory cytokines. These findings provide insight into potential mechanisms by which exposure to hyperoxia results in systemic inflammation

Vitamin A Metabolism: An Update

Retinoids are required for maintaining many essential physiological processes in the body, including normal growth and development, normal vision, a healthy immune system, normal reproduction, and healthy skin and barrier functions. In excess of 500 genes are thought to be regulated by retinoic acid. 11-cis-retinal serves as the visual chromophore in vision. The body must acquire retinoid from the diet in order to maintain these essential physiological processes. Retinoid metabolism is complex and involves many different retinoid forms, including retinyl esters, retinol, retinal, retinoic acid and oxidized and conjugated metabolites of both retinol and retinoic acid. In addition, retinoid metabolism involves many carrier proteins and enzymes that are specific to retinoid metabolism, as well as other proteins which may be involved in mediating also triglyceride and/or cholesterol metabolism. This review will focus on recent advances for understanding retinoid metabolism that have taken place in the last ten to fifteen years

Cooling system for the soft X-ray spectrometer onboard Astro-H

金沢大学理工研究域数物科学系The Soft X-ray Spectrometer (SXS) is a cryogenic high resolution X-ray spectrometer onboard the X-ray astronomy satellite Astro-H which will be launched in 2014. The detector array is cooled down to 50 mK using an adiabatic demagnetization refrigerator (ADR). The cooling chain from the room temperature to the ADR heat-sink is composed of superfluid liquid He, a Joule-Thomson cryocooler, and double-stage Stirling cryocoolers. It is designed to keep 30 l of liquid He for more than 5 years in the normal case, and longer than 3 years even if one of the cryocoolers fails. Cryogen-free operation is also possible in the normal case. It is fully redundant from the room temperature to the ADR heat-sink. © 2010 Elsevier Ltd

A genome-wide association study of anorexia nervosa suggests a risk locus implicated in dysregulated leptin signaling

J. Kaprio, A. Palotie, A. Raevuori-Helkamaa ja S. Ripatti ovat työryhmän Eating Disorders Working Group of the Psychiatric Genomics Consortium jäseniä. Erratum in: Sci Rep. 2017 Aug 21;7(1):8379, doi: 10.1038/s41598-017-06409-3We conducted a genome-wide association study (GWAS) of anorexia nervosa (AN) using a stringently defined phenotype. Analysis of phenotypic variability led to the identification of a specific genetic risk factor that approached genome-wide significance (rs929626 in EBF1 (Early B-Cell Factor 1); P = 2.04 x 10(-7); OR = 0.7; 95% confidence interval (CI) = 0.61-0.8) with independent replication (P = 0.04), suggesting a variant-mediated dysregulation of leptin signaling may play a role in AN. Multiple SNPs in LD with the variant support the nominal association. This demonstrates that although the clinical and etiologic heterogeneity of AN is universally recognized, further careful sub-typing of cases may provide more precise genomic signals. In this study, through a refinement of the phenotype spectrum of AN, we present a replicable GWAS signal that is nominally associated with AN, highlighting a potentially important candidate locus for further investigation.Peer reviewe
