The British Industrial Relations Bill – An Analysis

L'adoption, en décembre 1970, d'une nouvelle loi sur les relations industrielles en Angleterre a marqué de façon définitive, un nouveau départ pour le système de relations industrielles de ce pays. L'analyse des intentions du gouvernement sous-jacente à cette législation peut être divisée en trois parties : un examen de sa philosophie, les buts qui découlent de cette philosophie et les moyens choisis pour atteindre ces objectifs.Deux courts commentaires suffiraient pour résumer la philosophie du gouvernement lors de l'adoption de cette loi. D'abord, nous assistons à une extension du rôle de la loi en société démocratique vers un domaine presqu'entièrement exclu dans le passé : en second lieu, cette philosophie est en quelque sorte un nouveau départ radical - radical à cause de l'intervention de la loi dans un sous-système de la société dans lequel elle n'avait précédemment joué qu'un rôle très mineur avec le consentement général des parties impliquées. Quant à l'objectif fondamentale de cette nouvelle loi, il apparaît clairement qu'elle a pour but de renforcer l'économie. On a beaucoup mentionné les objectifs économiques et très peu parlé des buts sociaux de cette législation. Ces derniers seraient d'établir des normes nationales pour de meilleures relations industrielles, de protéger ceux qui se conforment à ces normes, de protéger les droits individuels au travail et de fournir de nouvelles méthodes de solution des conflits du travail.Quant aux moyens utilisés pour atteindre ces objectifs, notons que la réforme du système de négociation collective, le renforcement du syndicalisme, la diminution des grèves et la protection des droits individuels sont les principaux. Plus spécifiquement, citons le droit d'appartenir ou de ne pas appartenir à un syndicat, le droit d'être reconnu sous certaines conditions, l'enregistrement des syndicats, la présomption que toutes les conventions collectives sont contractuelles à moins qu'une des deux parties fasse de la sous-traitance, quelques limites à l'immunité totale des syndicats face aux poursuites légales en matière de dommages, quelques mécanismes de protection pour la communauté comme, par exemple, les votes secrets lors des grèves qui pourraient mettre en danger l'intérêt national, une mise en application sélective des conventions et des mécanismes qui ont pour but de contrôler qui va négocier pour les travailleurs dans certaines usines.Le gouvernement britannique a présenté un ensemble de propositions qui sont aussi claires qu'on pourrait s'y attendre à l'intérieur du domaine complexe des relations industrielles. Il est évident que l'interprétation de la future loi jouera un rôle important dans le résultat ultime. Une jurisprudence émergera qui guidera les participants au système de relations industrielles.Évaluer avec précision les conséquences ultimes d'une loi est évidemment très difficile. Les conclusions partielles que nous offrons sont alors basées sur les opinions d'observateurs désintéressés de la réalité anglaise. Un célèbre médiateur américain, Théodore Kheel, a comparé les propositions du gouvernement à la pratique américaine. Kheel justifie la comparabilité des deux réalités en avançant que le modèle britannique empruntait à trois lois américaines du travail, à savoir la Loi Wagner de 1935, le Taft-Hartley de 1947 et le Landum-Griffin de 1959.Notre interprétation de Kheel suggère quatre critiques importantes :a) La loi à elle seule, ne suffit pas pour garantir de véritables conventions collectives : celles-ci ont d'abord besoin du respect mutuel et du consentement des parties impliquées. Cet argument semble être très pertinent lorsque l'on considèrela proposition de donner à la Commission nationale des relations du travail, à la demande des deux parties, le pouvoir de rendre un accord obligatoire.b) Après examen des propositions, il semble trop facile d'éliminer le précompte syndical généralisé (P.S.G.) (après 2 ans, 20% des employés couverts par la convention, ou l'employeur, peuvent demander un vote secret afin d'annuler la convention). L'élimination fréquente du P.S.G. pourrait sérieusement affaiblir la position financière des syndicats britanniques. Il faut se rappeler que les syndicats anglais sont notoirement pauvres surtout lorsqu'on les compare aux unions américaines.c) Les propositions qui touchent la distinction entre les syndicats enregistrés et les autres organisations peuvent facilement entraîner l'isolation des meneurs des grèves illégales, grèves qui peuvent réussir à aliéner ces leaders. Par exemple, les chefs d'un syndicat enregistré peuvent pour éviter la responsabilité légale, dissuader les leaders locaux de recourir à des actions illégales. De telles pratiques peuvent facilement élargir l'écart entre les chefs nationaux et locaux et, par le fait même, encourager plutôt que le contraire de futures actions illégales.d) Finalement, on doit noter que les ambitions législatives du gouvernement britannique sont peut-être trop grandes. Les Américains ont eu besoin de trois lois entre 1935 et 1959 pour introduire une législation à peu près similaire. Le gouvernement se propose à l'intérieur d'une seule loi de relations industrielles d'éliminer l'immunité légale qui existe depuis presque 100 ans et de corriger presque tous les maux qui sont apparus durant cette période.In this paper, the authors attempt to analyse the government intention and to assess some of the possible implications of the proposed measures in the British government's industrial relations Bill passed on December 8, 1970

Dark matter relic density in Gauss-Bonnet braneworld cosmology

The relic density of symmetric and asymmetric dark matter in a Gauss-Bonnet (GB) modified Randall-Sundrum (RS) type II braneworld cosmology is investigated. The existing study of symmetric dark matter in a GB braneworld (Okada and Okada, 2009) found that the expansion rate was reduced compared to that in standard General Relativity (GR), thereby delaying particle freeze-out and resulting in relic abundances which are suppressed by up to O(10^−2). This is in direct contrast to the behaviour observed in RS braneworlds where the expansion rate is enhanced and the final relic abundance boosted. However, this finding that relic abundances are suppressed in a GB braneworld is based upon a highly contrived situation in which the GB era evolves directly into a standard GR era, rather than passing through a RS era as is the general situation. This collapse of the RS era requires equating the mass scale m(α) of the GB modification and the mass scale m(σ) of the brane tension. However, if the GB contribution is to be considered as the lowest order correction from string theory to the RS action, we would expect m(α) > m(σ). We investigate the effect upon the relic abundance of choosing more realistic values for the ratio Rm ≡ mα/mσ and find that the relic abundance can be either enhanced or suppressed by more than two orders of magnitude. However, suppression only occurs for a small range of parameter choices and, overwhelmingly, the predominant situation is that of enhancement as we recover the usual Randall-Sundrum type behaviour in the limit Rm >> 1. We use the latest observational bound Ω(DM)h^2 = 0.1187 ± 0.0017 to constrain the various model parameters and briefly discuss the implications for direct/indirect dark matter detection experiments as well as dark matter particle models

Spin-dipole induced lifetime of the least-bound quintet sigma state of He(2S)+He(2S)

The properties of the least-bound vibrational level (v=14) of the quintet sigma state formed during the ultracold collision of two spin-polarized metastable helium atoms are crucial to studies of photoassociation spectroscopy of metastable helium. We report a calculation of the autoionization lifetime of this state induced by spin-dipole coupling of the quintet sigma state to the singlet sigma state from which Penning and associative ionization processes are highly probable. We find a lifetime of about 150 microseconds, significantly larger than the recent experimental estimates of (4-5) microseconds.Comment: REVTEX4, four double-column page

Crystal structures of the GH18 domain of the bifunctional peroxiredoxin-chitinase CotE from Clostridium difficile

CotE is a coat protein that is present in the spores of Clostridium difficile, an obligate anaerobic bacterium and a pathogen that is a leading cause of antibiotic-associated diarrhoea in hospital patients. Spores serve as the agents of disease transmission, and CotE has been implicated in their attachment to the gut epithelium and subsequent colonization of the host. CotE consists of an N-terminal peroxiredoxin domain and a C-terminal chitinase domain. Here, a C-terminal fragment of CotE comprising residues 349-712 has been crystallized and its structure has been determined to reveal a core eight-stranded β-barrel fold with a neighbouring subdomain containing a five-stranded β-sheet. A prominent groove running across the top of the barrel is lined by residues that are conserved in family 18 glycosyl hydrolases and which participate in catalysis. Electron density identified in the groove defines the pentapeptide Gly-Pro-Ala-Met-Lys derived from the N-terminus of the protein following proteolytic cleavage to remove an affinity-purification tag. These observations suggest the possibility of designing peptidomimetics to block C. difficile transmission

Building development and roads: implications for the distribution of stone curlews across the Brecks

Background: Substantial new housing and infrastructure development planned within England has the potential to conflict with the nature conservation interests of protected sites. The Breckland area of eastern England (the Brecks) is designated as a Special Protection Area for a number of bird species, including the stone curlew (for which it holds more than 60% of the UK total population). We explore the effect of buildings and roads on the spatial distribution of stone curlew nests across the Brecks in order to inform strategic development plans to avoid adverse effects on such European protected sites. Methodology: Using data across all years (and subsets of years) over the period 1988 – 2006 but restricted to habitat areas of arable land with suitable soils, we assessed nest density in relation to the distances to nearest settlements and to major roads. Measures of the local density of nearby buildings, roads and traffic levels were assessed using normal kernel distance-weighting functions. Quasi-Poisson generalised linear mixed models allowing for spatial auto-correlation were fitted. Results: Significantly lower densities of stone curlew nests were found at distances up to 1500m from settlements, and distances up to 1000m or more from major (trunk) roads. The best fitting models involved optimally distance-weighted variables for the extent of nearby buildings and the trunk road traffic levels. Significance : The results and predictions from this study of past data suggests there is cause for concern that future housing development and associated road infrastructure within the Breckland area could have negative impacts on the nesting stone curlew population. Given the strict legal protection afforded to the SPA the planning and conservation bodies have subsequently agreed precautionary restrictions on building development within the distances identified and used the modelling predictions to agree mitigation measures for proposed trunk road developments

Hadronic B decays: Supersymmetric enhancement and a simple spectator model

Two aspects of hadronic B decays are investigated. Firstly, the supersymmetric enhancement of hadronic b decays by gluino penguin processes is studied through their effect on the Wilson coefficients of the effective Hamiltonian. Secondly, hadronization of the final state quarks is studied through a simple phase space spectator model.Comment: 24 pages, REVTEX, minor additional text and some references adde

Spatiotemporal Patterns in Nest Box Occupancy by Tree Swallows Across North America

Data from the North American Breeding Bird Survey (BBS) suggest that populations of aerial insectivorous birds are declining, particularly in northeastern regions of the continent, and particularly since the mid-1980s. Species that use nest boxes, such as Tree Swallows (Tachycineta bicolor), may provide researchers with large data sets that better reveal finer-scale geographical patterns in population trends. We analyzed trends in occupancy rates for ca. 40,000 Tree Swallow nest-box-years from 16 sites across North America. The earliest site has been studied intensively since 1969 and the latest site since 2004. Nest box occupancy rates declined significantly at five of six (83%) sites east of -78° W longitude, whereas occupancy rates increased significantly at four of ten sites (40%) west of -78° W longitude. Decreasing box occupancy trends from the northeast were broadly consistent with aspects of a previous analysis of BBS data for Tree Swallows, but our finding of instances of increases in other parts of the continent are novel. Several questions remain, particularly with respect to causes of these broad-scale geographic changes in population densities of Tree Swallows. The broad geographic patterns are consistent with a hypothesis of widespread changes in climate on wintering, migratory, or breeding areas that in turn may differentially affect populations of aerial insects, but other explanations are possible. It is also unclear whether these changes in occupancy rates reflect an increase or decrease in overall populations of Tree Swallows. Regardless, important conservation steps will be to unravel causes of changing populations of aerial insectivores in North America

Parental attributions of control for child behaviour and their relation to discipline practices in parents of children with and without developmental delays

Children with developmental delays (DD) are at risk for developing behavior problems. Research suggests that parents’ causal attributions for child behavior are related to parenting. This study investigated this association in parents of children with DD compared to parents of typically developing (TD) children. It specifically focused on attributions of child control by separating these from attributions of responsibility, blame and intent, and from attributions of parent control and responsibility. Fifty-one parents of children with DD and 69 parents of TD children completed two questionnaires. The Written Analogue Questionnaire measured causal attributions. The Parenting Scale measured dysfunctional discipline practices. Parents of children with DD viewed the child’s role in problematic behavior more positively while also viewing misbehavior as more fixed than parents of TD children. Parents of TD children who viewed their child as more in control over misbehavior used less dysfunctional discipline, but this association was not found for parents of children with DD. The results advance understanding of how parents perceive behavior problems in children with DD and the important role these perceptions play in parental behavior management strategies. More importantly, these perceptions relate to discipline practices differently for parents of children with DD compared to parents of TD children, highlighting that parent interventions should be adapted to the specific needs of parents of children with DD

Influence of design and material characteristics on 3D printed flow-cells for heat transfer-based analytical devices

Redesigning 3D-printed flow cells is reported used for heat transfer based detection of biomolecules from a flow-through system to an addition-type measurement cell. The aim of this study is to assess the performance of this new measurement design and critically analyse the influence of material properties and 3D printing approach on thermal analysis. Particular attention is paid to reduce the time to stabilisation, the sample volume in order to make the technique suitable for clinical applications, and improving the sensitivity of the platform by decreasing the noise and interference of air bubbles. The three different approaches that were studied included a filament polylactic acid cell using only fused filament fabrication (FFF), a resin cell printed using stereolitography (SLA), and finally a design made of copper, which was manufactured by combining metal injection moulding (MIM) with fused filament fabrication (FFF). Computational fluid dynamic (CFD) modelling was undertaken using ANSYS Fluent V18.1 to provide insight into the flow of heat within the measurement cell, facilitating optimisation of the system and theoretical response speed. It was shown that the measurement cells using SLA had the lowest noise (~ 0.6%) and shortest measurement time (15 min), whereas measurement cells produced using other approaches had lower specificity or suffered from voiding issues. Finally, we assessed the potential of these new designs for detection of biomolecules and amoxicillin, a commonly used beta lactam antibiotic, to demonstrate the proof of concept. It can be concluded that the resin addition-type measurement cells produced with SLA are an interesting affordable alternative, which were able to detect amoxicillin with high sensitivity and have great promise for clinical applications due to the disposable nature of the measurement cells in addition to small sample volumes

Impact of GnRH analogues on oocyte/embryo quality and embryo development in in vitro fertilization/intracytoplasmic sperm injection cycles: a case control study

<p>Abstract</p> <p>Background</p> <p>Despite the clinical outcomes of ovarian stimulation with either GnRH-agonist or GnRH-antagonist analogues for in vitro fertilization (IVF) being well analysed, the effect of analogues on oocyte/embryo quality and embryo development is still not known in detail. The aim of this case-control study was to compare the efficacy of a multiple-dose GnRH antagonist protocol with that of the GnRH agonist long protocol with a view to oocyte and embryo quality, embryo development and IVF treatment outcome.</p> <p>Methods</p> <p>Between October 2001 and December 2008, 100 patients were stimulated with human menopausal gonadotrophin (HMG) and GnRH antagonist in their first treatment cycle for IVF or intracytoplasmic sperm injection (ICSI). One hundred combined GnRH agonist + HMG (long protocol) cycles were matched to the GnRH antagonist + HMG cycles by age, BMI, baseline FSH levels and by cause of infertility. We determined the number and quality of retrieved oocytes, the rate of early-cleavage embryos, the morphology and development of embryos, as well as clinical pregnancy rates. Statistical analysis was performed using Wilcoxon's matched pairs rank sum test and McNemar's chi-square test. P < 0.05 was considered statistically significant.</p> <p>Results</p> <p>The rate of cytoplasmic abnormalities in retrieved oocytes was significantly higher with the use of GnRH antagonist than in GnRH agonist cycles (62.1% vs. 49.9%; P < 0.01). We observed lower rate of zygotes showing normal pronuclear morphology (49.3% vs. 58.0%; P < 0.01), and higher cell-number of preembryos on day 2 after fertilization (4.28 vs. 4.03; P < 0.01) with the use of GnRH antagonist analogues. The rate of mature oocytes, rate of presence of multinucleated blastomers, amount of fragmentation in embryos and rate of early-cleaved embryos was similar in the two groups. Clinical pregnancy rate per embryo transfer was lower in the antagonist group than in the agonist group (30.8% vs. 40.4%) although this difference did not reach statistical significance (P = 0.17).</p> <p>Conclusion</p> <p>Antagonist seemed to influence favourably some parameters of early embryo development dynamics, while other morphological parameters seemed not to be altered according to GnRH analogue used for ovarian stimulation in IVF cycles.</p
