Double jeopardy : a socio-demographic profile of homeless jobseekers aged 18-35

This article reports on socio-demographic research that was undertaken as part of a broader project to improve service delivery to homeless jobseekers aged 18-35 years (Grace et 01 2005). The broader project, known as Yp4, is a randomised controlled trial of joined up services and programs for young homeless jobseekers. Yp4 is an initiative of four organisations: Hanover Welfare Services, Brotherhood of St Laurence, Melbourne Citymission and Loddon Mallee Housing Services This paper does not provide detailed information about the Yp4 trial, rather it reports on socio-demographic research undertaken to set the context in which Yp4 operates. For further details regarding Yp4 please see Horn (2004). When we set out to prepare a socio-demographic profile of homeless jobseekers aged 18-35 years, we found two main ways to count homelessness and at least two ways to quantify unemployment. Obtaining data and assessing its quality was far from easy, and this research was an exercise in frustration and perseverance. In this article we discuss the complexities of counting homelessness and unemployment, and the educated guesswork involved in estimating numbers of homeless jobseekers. We present a tentative socio-demographic profile; and we make suggestions regarding better access to data in the future

Avec les nouvelles technologies, un rapport nouveau à l’écriture ?

A partir du témoignage d’une dizaine d’enseignants sur leurs pratiques de classe, les représentations sur les comportements des élèves sont analysées. Le rapport à l’écriture dans les classes de cours moyen a-t-il évolué avec l’introduction des ordinateurs ? Si tel est le cas, quelles sont les tendances significatives repérées par ces témoins ? Dans l’ensemble, ces maîtres d’école primaire, parmi les plus engagés dans la production d’écrit par ordinateur, dans un secteur donné, apparaissent d’abord comme des pionniers… de l’écriture. Ce sont en effet bien souvent ceux qui se sont inspirés des théories diffusées par les chercheurs, des modèles de la génétique du texte, de l’information et de la communication ou de la psychologie cognitive, par exemple. Pour les enseignants, l’informatique, le plus souvent, est venue après, en adjuvant, comme un outil de plus au service de l’écriture. Cependant, chemin faisant, ces technologies numériques, souvent restreintes à l’ordinateur, au traitement de texte et à Internet, ont quelque peu modifié le rapport que maîtres et élèves ont avec la langue écrite. Les adultes ont bien saisi la valeur ajoutée que ces techniques apportent notamment à la révision des textes et à leur mise en forme. Leurs récits insistent sur l’émergence de certains types d’écrits, sans doute induits par l’utilisation de certains logiciels, dans des environnements particuliers : l’écrit, comme tout apprentissage scolaire, apparaît ainsi comme dépendant du contexte et des contraintes matérielles. Ces enseignants s’attardent aussi sur les pratiques d’écriture de certains de leurs élèves, à la maison, et sur le regard que les parents portent sur ces usages. Plus que jamais, au moment où l’écrit circule plus librement entre l’école et la famille, comme, d’une manière générale, entre le monde du travail et la sphère domestique, par le canal de ces technologies, le milieu scolaire est conduit à s’interroger sur ses missions spécifiques. Apprendre aux élèves à écrire, paraît être la première d’entre elles. Cet apprentissage peut-il tirer parti de leur fascination pour les écrans ? Pour décrire ces situations, où se mêlent l’écrit, la lecture et les échanges oraux, des emprunts peuvent être faits à différents modèles linguistiques et didactiques. Dans le cadre de recherches sur ces usages de l’écrit, quel statut accorder au recueil de témoignages, à l’analyse des représentations, aux observations et aux descriptions de pratiques

Use of tobacco retail permitting to reduce youth access and exposure to tobacco in Santa Clara County, California

AbstractObjectiveTo target youth smoking, the impact of a local tobacco retail permit was evaluated on the number and location of tobacco retailers, and on the level of enforcement and compliance with tobacco sales regulations from 2010 to 2012 within unincorporated Santa Clara County, California.MethodsGeographic Information Systems (GIS) mapping of each of 36 tobacco retailers pre- and post-intervention, observational surveys of tobacco retail environments pre- and post-intervention, and post-intervention enforcement surveys to measure location of sales, level of enforcement action, and compliance with laws governing sale of tobacco products were conducted.ResultsEleven (30.6%) of the initial 36 retailers selling tobacco at the start of the intervention stopped selling tobacco post intervention. Of these 11 retailers, one was within 500feet of another retailer, and three were within 1000feet of a K–12 school. Ten (91%) of the retailers who stopped selling tobacco were non-traditional retailers.ConclusionAn immediate reduction in the number of stores selling tobacco occurred following implementation of tobacco retail permitting. Post-implementation, all retailers who underwent compliance checks were in compliance with laws prohibiting sales of tobacco to minors. Compliance with laws governing the sale of tobacco has potential to reduce access and use of tobacco products by youth

FIREBall-2: advancing TRL while doing proof-of-concept astrophysics on a suborbital platform

Here we discuss advances in UV technology over the last decade, with an emphasis on photon counting, low noise, high efficiency detectors in sub-orbital programs. We focus on the use of innovative UV detectors in a NASA astrophysics balloon telescope, FIREBall-2, which successfully flew in the Fall of 2018. The FIREBall-2 telescope is designed to make observations of distant galaxies to understand more about how they evolve by looking for diffuse hydrogen in the galactic halo. The payload utilizes a 1.0-meter class telescope with an ultraviolet multi-object spectrograph and is a joint collaboration between Caltech, JPL, LAM, CNES, Columbia, the University of Arizona, and NASA. The improved detector technology that was tested on FIREBall-2 can be applied to any UV mission. We discuss the results of the flight and detector performance. We will also discuss the utility of sub-orbital platforms (both balloon payloads and rockets) for testing new technologies and proof-of-concept scientific ideas

Effects of single-dose injectable paracetamolversus propacetamol in pain management after minor gynecologic surgery: A multicenter, randomized, double-blind, active-controlled, two-parallel-group study

AbstractBackground:Intravenous administration is the route of choice for drug therapy in the immediate postoperative period. Propacetamol (ProAPAP), an injectable prodrug of paracetamol requiring reconstitution, has demonstrated efficacy in managing acute pain and fever. However, it has been associated with pain at the injection site. A stable, ready-to-use formulation of paracetamol solution infused intravenously (IV-APAP) has been developed and might be associated with less pain at the injection site compared with ProAPARObjective:The objective of this study was to assess the tolerability and efficacy of a single dose of IV APAP 1 g compared with those of a single dose of ProAPAP 2 g in patients with moderate to severe pain after minor gynecologic surgery.Methods:This single-dose, randomized, double-blind, active-controlled,2-parallel-group study was conducted at 23 hospitals and outpatient clinics in France. After minor gynecologic surgery, patients reporting moderate to severe pain were randomized to receive a single 15-minute infusion of IV-APAP 1 g or ProAPAP 2 g (bioeyuivalent doses). Tolerability was monitored using local and systemic adverse event (AE) reporting, clinical examination including vital sign measurement, and patients' ratings of acceptability of the infusion. Efficacy end points included pain intensity at 0, 1, 2, 4, and 6 hours; median time to rescue medication (defined as the time at which 50% of patients requested rescue medication); and percentage of patients requesting rescue medication. Patients' satisfaction with the study drugs was assessed using patient's global evaluation (PGE) and the percentage of patients willing to receive the treatment again.Results:Of the 163 women who were randomized, 161 received the studymedication. The IV-APAP group comprised 80 patients (mean [SD] age, 38.3 [12.8] years [range, 18.0-69.0 years]; mean [SD] weight, 61.1 [11.0] kg [range, 49.0–90.0 kg]), and the ProAPAP group comprised 81 patients (mean [SD] age, 33.9 [12.0] years [range, 18.0–67.0 years]; mean [SD] weight, 61.6 [10.2] kg [range, 42.0–95.5 kg]); the difference in mean age between the 2 groups was statistically significant (P < 0.05). The incidence of local treatment-emergent AEs (TEAEs) was significantly lower in the IV-APAP group compared with that in the ProAPAP group (7.5% vs 38.3%; P < 0.001). No between-group differences in the incidence of systemic TEAEs was found. All patients in the IV-APAP group found the infusion tolerable, compared with 95% of patients in the ProAPAP group. The median time to rescue medication was not evaluated because <50% of the patients in each group requested it. No significant differences in mean pain intensity score or percentage of patients requesting rescue medication were found between the 2 groups at any time point. The percentages of patients in the IV-APAP and ProAPAP groups who rated the study medication as good or excellent on the PGE (83.6% vs 75.6%; P < 0.05) and who were willing to receive the same treatment again (96.0% vs 81.0%; P = 0.005) were significantly higher with IV-APAP compared with ProAPAPConclusion:In these patients with moderate to severe pain after minor gynecologic surgery, a single dose of IV-APAP was associated with better local tolerability, similar analgesic efficacy, and greater patient satisfaction compared with a single bioequivalent dose of ProAPAP

Recessive RYR1 mutations cause unusual congenital myopathy with prominent nuclear internalization and large areas of myofibrillar disorganization.

International audienceAIMS: To report the clinical, pathological and genetic findings in a group of patients with a previously not described phenotype of congenital myopathy due to recessive mutations in the gene encoding the type 1 muscle ryanodine receptor channel (RYR1). METHODS: Seven unrelated patients shared a predominant axial and proximal weakness of varying severity, with onset during the neonatal period, associated with bilateral ptosis and ophthalmoparesis, and unusual muscle biopsy features at light and electron microscopic levels. RESULTS: Muscle biopsy histochemistry revealed a peculiar morphological pattern characterized by numerous internalized myonuclei in up to 51% of fibres and large areas of myofibrillar disorganization with undefined borders. Ultrastructurally, such areas frequently occupied the whole myofibre cross section and extended to a moderate number of sarcomeres in length. Molecular genetic investigations identified recessive mutations in the ryanodine receptor (RYR1) gene in six compound heterozygous patients and one homozygous patient. Nine mutations are novel and four have already been reported either as pathogenic recessive mutations or as changes affecting a residue associated with dominant malignant hyperthermia susceptibility. Only two mutations were located in the C-terminal transmembrane domain whereas the others were distributed throughout the cytoplasmic region of RyR1. CONCLUSION: Our data enlarge the spectrum of RYR1 mutations and highlight their clinical and morphological heterogeneity. A congenital myopathy featuring ptosis and external ophthalmoplegia, concomitant with the novel histopathological phenotype showing fibres with large, poorly delimited areas of myofibrillar disorganization and internal nuclei, is highly suggestive of an RYR1-related congenital myopathy

Exon skipping as a therapeutic strategy applied to an RYR1 mutation with pseudo-exon inclusion causing a severe core myopathy.

International audienceCentral core disease is a myopathy often arising from mutations in the type 1 ryanodine receptor (RYR1) gene, encoding the sarcoplasmic reticulum calcium release channel RyR1. No treatment is currently available for this disease. We studied the pathological situation of a severely affected child with two recessive mutations, which resulted in a massive reduction in the amount of RyR1. The paternal mutation induced the inclusion of a new in-frame pseudo-exon in RyR1 mRNA that resulted in the insertion of additional amino acids leading to the instability of the protein. We hypothesized that skipping this additional exon would be sufficient to restore RyR1 expression and to normalize calcium releases. We therefore developed U7-AON lentiviral vectors to force exon skipping on affected primary muscle cells. The efficiency of the exon skipping was evaluated at the mRNA level, at the protein level, and at the functional level using calcium imaging. In these affected cells, we observed a decreased inclusion of the pseudo-exon, an increased RyR1 protein expression, and a restoration of calcium releases of normal amplitude either upon direct RyR1 stimulation or in response to membrane depolarization. This study is the first demonstration of the potential of exon-skipping strategy for the therapy of central core disease, from the molecular to the functional level
