Since 1986, the Canadian Public Administration is required to analyze the socio-economic impact of new regulatory requirements or regulatory changes. To report on its analysis, a Regulatory Impact Analysis Statement (RIAS) is produced and published in the Canada Gazette with the proposed regulation to which it pertains for notice to, and comments by, interested parties. After the allocated time for comments has elapsed, the regulation is adopted with a final version of the RIAS. Both documents are again published in the Canada Gazette. As a result, the RIAS acquires the status of an official public document of the Government of Canada and its content can be argued in courts as an extrinsic aid to the interpretation of a regulation. In this paper, an analysis of empirical findings on the uses of this interpretative tool by the Federal Court of Canada is made. A sample of decisions classified as unorthodox show that judges are making determinations on the basis of two distinct sets of arguments built from the information found in a RIAS and which the author calls “technocratic” and “democratic”. The author argues that these uses raise the general question of “What makes law possible in our contemporary legal systems”? for they underline enduring legal problems pertaining to the knowledge and the acceptance of the law by the governed. She concludes that this new interpretive trend of making technocratic and democratic uses of a RIAS in case law should be monitored closely as it may signal a greater change than foreseen, and perhaps an unwanted one, regarding the relationship between the government and the judiciary.

Il est relativement bien établi que les crises focales entraînent une augmentation régionale du flot sanguin dans le but de soutenir la demande énergétique en hémoglobine oxygénée des neurones épileptiques. Des changements hémodynamiques précoces ont également été rapportés dans la région homologue controlatérale, bien que ceci ait été moins bien caractérisé. Dans cette étude, notre objectif est de mieux caractériser, lors de crises focales, la nature des changements hémodynamiques précoces dans la région homologue controlatérale au foyer épileptique. L'imagerie optique intrinsèque (IOI) et la microscopie deux-photons sont utilisées pour étudier les changements hémodynamiques dans la région homologue controlatérale au site de crises focales induites par l’injection de 4-aminopyridine (4-AP) dans le cortex somatosensitif ipsilatéral de souris. Dans l'étude d'IOI, des changements de l’oxyhémoglobine (HbO), de la désoxyhémoglobine (HbR) et du débit sanguin cérébral ont été observées dans la région homologue controlatérale au site de crises focales lors de toutes les crises. Toutefois, ces changements étaient hétérogènes, sans patron cohérent et reproduisible. Nos expériences avec la microscopie deux-photons n’ont pas révélé de changements hémodynamiques significatifs dans la région homotopique controlatérale lors de trains de pointes épileptiques. Nos résultats doivent être interprétés avec prudence compte tenu de plusieurs limitations: d’une part absence de mesures électrophysiologiques dans la région d’intérêt controlatérale au foyer simultanément à l’imagerie deux-photons et à l'IOI; d’autre part, lors des expériences avec le deux-photons, incapacité à générer de longues décharges ictales mais plutôt des trains de pointes, couverture spatiale limitée de la région d’intérêt controlatérale, et faible puissance suite au décès prématuré de plusieurs souris pour diverses raisons techniques. Nous terminons en discutant de divers moyens pour améliorer les expériences futures.

This paper presents the findings of a podcasting trial held in 2007-2008 within the Faculty of Economics and Business at the University of Sydney, Australia. The trial investigates the value of using short-format podcasts to support assessment for postgraduate and undergraduate students. A multi-method approach is taken in investigating perceptions of the benefits of podcasting, incorporating surveys, focus groups and interviews. The results show that a majority of students believe they gained learning benefits from the podcasts and appreciated the flexibility of the medium to support their learning, and the lecturers felt the innovation helped diversify their pedagogical approach and support a diverse student population. Three primary conclusions are presented: (1) most students reject the mobile potential of podcasting in favour of their traditional study space at home; (2) what students and lecturers value about this podcasting design overlap; (3) the assessment-focussed, short-format podcast design may be considered a successful podcasting model. The paper finishes by identifying areas for future research on the effective use of podcasting in learning and teaching.

The non-steroidal anti-inflammatory drug (NSAID) ibuprofen (IB) is a widely used pharmaceutical that can be found in several freshwater ecosystems. Acute toxicity studies with Daphnia magna suggest that the 48 h EC50 (immobilisation) is 10-100 mg IB l(-1). However, there are currently no chronic IB toxicity dataon arthropod populations, and the aquatic life impacts of such analgesic drugs are still undefined. We performed a 14-day exposure of D. magna to IB as a model compound (concentration range: 0, 20, 40 and 80 mg IB l(-1)) measuring chronic effects on life history traits and population performance. Population growth rate was significantly reduced at all IB concentrations, although survival was only affected at 80 mg IB l(-1). Reproduction, however, was affected at lower concentrations of IB (14-day EC50 of 13.4 mg IB l(-1)), and was completely inhibited at the highest test concentration. The results from this study indicate that the long-term crustacean population consequences of a chronic IB exposure at environmentally realistic concentrations (ng l(-1) to mu g l(-1)) would most likely be of minor importance. We discuss our results in relation to recent genomic studies, which suggest that the potential mechanism of toxicity in Daphnia is similar to the mode of action in mammals, where IB inhibits eicosanoid biosynthesis.

The currently available model-based global data sets of atmospheric circulation are a by-product of the daily requirement of producing initial conditions for numerical weather prediction (NWP) models. These data sets have been quite useful for studying fundamental dynamical and physical processes, and for describing the nature of the general circulation of the atmosphere. However, due to limitations in the early data assimilation systems and inconsistencies caused by numerous model changes, the available model-based global data sets may not be suitable for studying global climate change. A comprehensive analysis of global observations based on a four-dimensional data assimilation system with a realistic physical model should be undertaken to integrate space and in situ observations to produce internally consistent, homogeneous, multivariate data sets for the earth's climate system. The concept is equally applicable for producing data sets for the atmosphere, the oceans, and the biosphere, and such data sets will be quite useful for studying global climate change.

In this paper we present the capability of a new network of field mill sensors to monitor the atmospheric electric field at various locations in South America; we also show some early results. The main objective of the new network is to obtain the characteristic Universal Time diurnal curve of the atmospheric electric field in fair weather, known as the Carnegie curve. The Carnegie curve is closely related to the current sources flowing in the Global Atmospheric Electric Circuit so that another goal is the study of this relationship on various time scales (transient/monthly/seasonal/annual). Also, by operating this new network, we may also study departures of the Carnegie curve from its long term average value related to various solar, geophysical and atmospheric phenomena such as the solar cycle, solar flares and energetic charged particles, galactic cosmic rays, seismic activity and specific meteorological events. We then expect to have a better understanding of the influence of these phenomena on the Global Atmospheric Electric Circuit and its time-varying behavior.

Purpose – The purpose of this paper is to demonstrate how strategy is developed and implemented within a subsidiary of a global organization, the relationship between subsidiary and headquarters and the need for continuous change and adaption to remain relevant. Furthermore, this case study describes a successful process of invention and adoption. Design/methodology/approach – The paper draws on documentary evidence and a semistructured interview with Jill McDonald CEO and President of McDonald’s Northern Europe Division with responsibility for the UK, Sweden, Finland, Denmark, Norway and the Republic of Ireland. Management research rarely captures the views of the top executive, yet the top executives have a broad picture and are key strategic decision makers. Findings – The case study and interview offers a unique insight into factors contributing to McDonald’s unprecedented success (it has paid an increased dividend for the past 37 years). It also sheds light on its successful internationalization strategy. Originality/value – The case study draws on published material and augments this with an in-depth interview with the Chief Executive. Very few case studies offer insight into the thinking of a Chief Executive managing a subsidiary of a global organization. Its value lies in the lessons that managers and students of management can draw on the approach adopted by a highly successful global organization.

This report provides case studies of Early Warning Systems (EWSs) and risk assessments encompassing three main hazard types: drought; flood and cyclone. The case studies are taken from ten countries across three continents (focusing on Africa, South Asia and the Caribbean). The case studies have been developed to assist the UK Department for International Development (DFID) to prioritise areas for Early Warning System (EWS) related research under their ‘Science for Humanitarian Emergencies and Resilience’ (SHEAR) programme. The aim of these case studies is to ensure that DFID SHEAR research is informed by the views of Non-Governmental Organisations (NGOs) and communities engaged with Early Warning Systems and risk assessments (including community-based Early Warning Systems). The case studies highlight a number of challenges facing Early Warning Systems (EWSs). These challenges relate to financing; integration; responsibilities; community interpretation; politics; dissemination; accuracy; capacity and focus. The case studies summarise a number of priority areas for EWS related research: • Priority 1: Contextualising and localising early warning information • Priority 2: Climate proofing current EWSs • Priority 3: How best to sustain effective EWSs between hazard events? • Priority 4: Optimising the dissemination of risk and warning information • Priority 5: Governance and financing of EWSs • Priority 6: How to support EWSs under challenging circumstances • Priority 7: Improving EWSs through monitoring and evaluating the impact and effectiveness of those systems

This thesis tends to study the origins and developments of the restoration in Iran from its very first moments till the Islamic revolution of 1978. The thesis is its first study of its kind. While almost all recent occidental ideologies regarding the thematic of restoration and conservation of historic monuments are translated and published in Iran, very little efforts have been done regarding the study of the origins of the formation of restoration in the country. The diversity of Iranian contexts, multiplicity of the intervening factors and other factors characterized a different background for the raise and developments of restoration in the country; in the thesis the influencing and characterizing factors in the formation and development of restoration in Iran will be defined and studied in detail with relative examples; due to the complexity of the Iranian context and in order to consider all influencing and characterizing factors the thesis, parallel to have formation and development of restoration, as the main scope of the research, the developments influencing factors will be confronted with necessary flashbacks to the main theme, when and where necessary. A great care will be given to the period of the activity of the restoration experts of IsMEO which is thesis will be called as the period of the introduction of the modern principles of restoration into Iranian context; the fundamental ideologies, practical and theoretical principles of IsMEO will be identified and studied in details; important case of studies of the restoration of IsMEO will be analyzed in details and the innovative aspect of the presence of Italian experts of IsMEO will be revealed.

Bone remodelling is a fundamental mechanism for removing and replacing bone during adaptation of the skeleton to mechanical loads. Skeletal unloading leads to severe hypoxia (1%O2) in the bone microenvironment resulting in imbalanced bone remodelling that favours bone resorption. Hypoxia, in vivo, is a physiological condition for osteocytes, 5% O2 is more likely physiological for osteocytes than 20% O2, as osteocytes are embedded deep inside the mineralized bone matrix. Osteocytes are thought to be the mechanosensors of bone and have been shown to orchestrate bone formation and resorption. Oxygen-deprived osteocytes seem undergo apoptosis and actively stimulate osteoclasts. Hypoxia and oxidative stress increase 150-kDa oxygen-regulated protein (ORP 150) expression in different cell types. It is a novel endoplasmic-reticulum-associated chaperone induced by hypoxia/ischemia. It well known that ORP 150 plays an important role in the cellular adaptation to hypoxia, as anti-apoptotic factor, and seems to be involved in osteocytes differentiations. The aims of the present study are 1) to determine the cellular and molecular response of the osteocytes at two different conditions of oxygen deprivation, 1% and 5% of O2 compared to the atmospheric oxygen concentration at several time points. 2) To clarify the role of hypoxic osteocytes in bone homeostasis through the detection of releasing of soluble factors (RANKL, OPG, PGE2 and Sclerostin). 3) To detect the activation of osteoclast and osteoblast induced by condition media collected from hypoxic and normoxic osteocytes. The data obtained in this study shows that hypoxia compromises the viability of osteocytes and induces apoptosis. Unlike in other cells types, ORP 150 in MLO-Y4 does not seem to be regulated early during hypoxia. The release of soluble factors and the evaluation of osteoclast and osteoblast activation shows that osteocytes, grown under severe oxygen deprivation, play a role in the regulation of both bone resorption and bone formation.

Calf losses (CL, mortality and unwanted early slaughter) in veal production are of great economic importance and an indicator of welfare. The objective of the present study was to evaluate CL and the causes of death on farms with a specific animal welfare standard (SAW) which exceeds the Swiss statutory regulations. Risk factors for CL were identified based on information about management, housing, feeding, and medication. In total, 74 production cohorts (2783 calves) of 15 farms were investigated. CL was 3.6%, the main causes of death were digestive disorders (52%), followed by respiratory diseases (28%). Factors significantly associated with an increased risk for CL were a higher number of individual daily doses of antibiotics (DDA), insufficient wind deflection in winter, and male gender. For administration of antibiotics to all calves of the cohort, a DDA of 14-21 was associated with a decreased risk for CL compared to a DDA of 7-13 days.

Objective Non-adherence to medication is common among coronary heart disease patients. Non-adherence to medication may be either intentional or unintentional. In this analysis we provide estimates of intentional and unintentional non-adherence in the year following an acute coronary syndrome (ACS). Method In this descriptive prospective observational study of patients with confirmed ACS medication adherence measures were derived from responses to the Medication Adherence Report Scale at approximately 2 weeks (n = 223), 6 months (n = 139) and 12 months (n = 136) following discharge from acute treatment for ACS. Results Total medication non-adherence was 20%, 54% and 53% at each of these time points respectively. The corresponding figures for intentional non-adherence were 8%, 15% and 15% and 15%, 52% and 53% for unintentional non-adherence. There were significant increases in the levels of medication non-adherence between the immediate discharge period (2 weeks) and 6 months that appeared to stabilize between 6 and 12 months after acute treatment for ACS. Conclusion Unintentional non-adherence to medications may be the primary form of non-adherence in the year following ACS. Interventions delivered early in the post-discharge period may prevent the relatively high levels of non-adherence that appear to become established by 6 months following an ACS.
