Legislative Change and Strike Activity in Canada, 1926-1974

Le présent article tente d'expliquer les variations à long terme des grèves au Canada pendant la période 1926-1974. À cette fin, il examine les effets de diverses variables d'ordre économique et organisationnel sur les types de conflits du travail. L'article s'efforce de replacer la grève dans son contexte politique en observant comment les modifications apportées à la législation fédérale du travail ont influencé au cours de ces années les types de grèves survenus au Canada. Ce qui ressort de cette étude, c'est que d'une part, le type de grève varie en fonction de la situation économique et de la capacité des syndicats d'imposer leurs revendications et que, d'autre part, la législation du travail influence le rapport entre les grèves et les deux variables qui viennent d'être citées.Les effets de nombreux facteurs économiques ainsi que de l'activité syndicale ont été étudiés en fonction de trois mesures d'évaluation des grèves, soit la fréquence, l'amplitude et la durée de la grève. On l'a fait pour l'ensemble de la période. Par la suite, les séries chronologiques furent scindées en choisissant une mesure législative fédérale (le C.P. 1003) comme point de rupture. Cette analyse confirme l'importance d'une législation du travail favorable aux travailleurs en tant que variable dans le rapport entre la situation économique et l'action syndicale d'une part, et les grèves, d'autre part. L'examen des données révèle très clairement que les modifications apportées à la législation en 1944 ont eu un impact significatif sur les causes déterminantes des grèves. Durant la période antérieure à 1944, l'état de l'organisation syndicale était la cause principale des variations dans les grèves. Après 1944, la négociation collective s'est institutionnalisée et la situation économique devint la cause principale de la décision de déclencher et de poursuivre les grèves.The authors examine long term variations in the level of strike activity in Canada between 1926 and 1974 by examining the effects of several economic and organizational variables on the pattern of industrial conflict

Establishing a meaningful human rights due diligence process for corporations : learning from experience of human rights impact assessment

The United Nations Special Representative of the Secretary-General on Business and Human Rights, Professor John Ruggie, has constructed a new international framework, which is set to become the cornerstone for all action on human rights and business at the international level. The principle of human rights due diligence (HRDD) is the central component of the corporate duty to respect human rights within that framework. This article argues that Ruggie's HRDD principle contains the majority of the core procedural elements that a reasonable human rights impact assessment (HRIA) process should incorporate. It is likely that the majority of corporations will adopt HRIA as a mechanism for meeting their due diligence responsibilities. However, in the context of the contentious debate around corporate human rights performance, the current state of the art in HRIA gives rise to concerns about the credibility and robustness of likely practice. Additional requirements are therefore essential if HRDD is to have a significant impact on corporate human rights performance – requirements in relation to transparency; external participation and verification; and independent monitoring and review

Young children's research: children aged 4-8 years finding solutions at home and at school

Children's research capacities have become increasingly recognised by adults, yet children remain excluded from the academy, with reports of their research participation generally located in adults' agenda. Such practice restricts children's freedom to make choices in matters affecting them, underestimates children’s capabilities and denies children particular rights. The present paper reports on one aspect of a small-scale critical ethnographic study adopting a constructivist grounded approach to conceptualise ways in which children's naturalistic behaviours may be perceived as research. The study builds on multi-disciplinary theoretical perspectives, embracing 'new' sociology, psychology, economics, philosophy and early childhood education and care (ECEC). Research questions include: 'What is the nature of ECEC research?' and 'Do children’s enquiries count as research?' Initially, data were collected from the academy: professional researchers (n=14) confirmed 'finding solutions' as a research behaviour and indicated children aged 4-8 years, their practitioners and primary carers as 'theoretical sampling'. Consequently, multi-modal case studies were constructed with children (n=138) and their practitioners (n=17) in three ‘good’ schools, with selected children and their primary carers also participating at home. This paper reports on data emerging from children aged 4-8 years at school (n=17) and at home (n=5). Outcomes indicate that participating children found diverse solutions to diverse problems, some of which they set themselves. Some solutions engaged children in high order thinking, whilst others did not; selecting resources and trialing activities engaged children in 'finding solutions'. Conversely, when children's time, provocations and activities were directed by adults, the quality of their solutions was limited, they focused on pleasing adults and their motivation to propose solutions decreased. In this study, professional researchers recognised 'finding solutions' as research behaviour and children aged 4-8 years naturalistically presented with capacities for finding solutions; however, the children's encounters with adults affected the solutions they found

A Review of the Canadian Space Program

This paper reviews the history of Canadian activities in space from the early Alouette I satellite to Canada\u27s present involvement in the Space Shuttle Remote Manipulator System (SRMS) program. The SRMS program is being executed by Spar Aerospace Limited* through, an international agreement between the National Aeronautics and Space Administration (NASA) and the National Research Council of Canada (NRCC). As the first flight SRMS reaches completion at Spar, the program is reviewed. The SRMS is described in terms of its subsystems, its of control and performance requirements and the current status of the hardware is examined. Delivery to NASA JSC of the first flight system is scheduled in 1980. In conclusion, the paper highlights the benefits which accrue from international cooperation at the industrial level in space programs and. makes a case for the continuance of such arrangements

Observation of Bs0→J/ψf0(980)B_s^0\to J/\psi f_0(980) and Evidence for Bs0→J/ψf0(1370)B_s^0\to J/\psi f_0(1370)

We report the first observation of $B_s^0\to J/\psi f_0(980)$ and first evidence for $B_s^0\to J/\psi f_0(1370)$, which are CP eigenstate decay modes. These results are obtained from $121.4\;\mathrm{fb}^{-1}$ of data collected at the $\Upsilon(5S)$ resonance with the Belle detector at the KEKB $e^+e^-$ collider. We measure the branching fractions $\mathcal{B}(B_s^0\to J/\psi f_0(980);f_0(980)\to\pi^+\pi^-)=(1.16^{+0.31}_{-0.19}(\mathrm{stat.})^{+0.15}_{-0.17}(\mathrm{syst.})^{+0.26}_{-0.18}(N_{B_s^{(*)}\bar B_s^{(*)}})) \times 10^{-4}$ with a significance of $8.4\sigma$, and $\mathcal{B}(B_s^0\to J/\psi f_0(1370);f_0(1370)\to\pi^+\pi^-)=(0.34^{+0.11}_{-0.14}(\mathrm{stat.})^{+0.03}_{-0.02}(\mathrm{syst.})^{+0.08}_{-0.05}(N_{B_s^{(*)}\bar B_s^{(*)}})) \times 10^{-4}$ with a significance of $4.2\sigma$. The last error listed is due to uncertainty in the number of produced $B_s^{(*)}\bar B_s^{(*)}$ pairs.Comment: 5 pages, 2 figures, 2 tables, published in PR

Rapid System to Quantitatively Characterize the Airborne Microbial Community

Bioaerosols have been linked to a wide range of different allergies and respiratory illnesses. Currently, microorganism culture is the most commonly used method for exposure assessment. Such culture techniques, however, generally fail to detect between 90-99% of the actual viable biomass. Consequently, an unbiased technique for detecting airborne microorganisms is essential. In this Phase II proposal, a portable air sampling device his been developed for the collection of airborne microbial biomass from indoor (and outdoor) environments. Methods were evaluated for extracting and identifying lipids that provide information on indoor air microbial biomass, and automation of these procedures was investigated. Also, techniques to automate the extraction of DNA were explored

Study of time-dependent CP violation in B0 -> J/Psi pi0 decays

We report a measurement of CP asymmetry parameters in the decay B0(B0bar) -> J/Psi pi0, which is governed by the b->c cbar d transition. The analysis is based on a 140/fb data sample accumulated at the Upsilon(4S) resonance by the belle detector at the KEKB asymmetric-energy e+e- collider. We fully reconstruct one neutral B meson in the J/Psi pi0 final state. The accompanying B meson flavor is identified by its decay products. From the distribution of proper time intervals between the two B decays, we obtain the following CP-violating parameters: S_{J/Psi pi0}=-0.72+-0.42+-0.09 and A_{J/Psi pi0}=-0.01 +-0.29+-0.03.Comment: 5 pages, 2 figures, submitted to PR

Search for the Lepton-Flavor-Violating Decay τ−→μ−η\tau^- \to \mu^- \eta at Belle

We have searched for the Lepton Flavor Violating decay $\tau^- \to \mu^- \eta$ using a data sample of 84.3 fb$^{-1}$ accumulated with the Belle detector at KEK. The $\eta$-meson was detected through the decay modes: $\eta \to \gamma\gamma$ and $\pi^+\pi^-\pi^0$. No signal candidates are found, and we obtain an upper limit for the branching fraction ${\cal B}(\tau^- \to \mu^- \eta)<3.4\times 10^{-7}$ at the 90% confidence level.Comment: Submitted to Phys.Rev.Let
