Wildlife tourism in Scotland – the example of grouse shooting

Wildlife tourism in Scotland has seen a recent increase in profile, with two reports providing new figures on the economic value of the activity. The reports, by the Scottish Government and Scottish Natural Heritage (SNH), seem likely to generate policy responses to further develop the sector

Strenght training methods and the work of Arthur Jones

This article is not available through ChesterRep. It is available at http://www.asep.org/files/Smith.pdfThis paper reviews research evidence relating to the strength training advice offered by Arthur Jones, founder and retired Chairman of Nautilus Sports/Medical Industries and MedX Corporation. Jones advocated that those interested in improving their muscular size, strength, power and/or endurance should perform one set of each exercise to muscular failure (volitional fatigue), train each muscle group no more than once (or, in some cases, twice) per week, perform each exercise in a slow, controlled manner and perform a moderate number of repetitions (for most people, ~8-12). This advice is very different to the strength training guidelines offered by the National Strength and Conditioning Association, the American College of Sports Medicine and most exercise physiology textbooks. However, in contrast to the lack of scientific support for most of the recommendations made by such bodies and in such books, Jones' training advice is strongly supported by the peer-reviewed scientific literature, a statement that has recently been supported by a review of American College of Sports Medicine resistance training guidelines. Therefore, we strongly recommend Jones' methods to athletes and coaches, as they are time-efficient and optimally efficacious, and note that, given his considerable contribution to the field of strength training, academic recognition of this contribution is long overdue

A new biosecurity investment decision framework to promote more efficient biosecurity policy

Australian governments spend millions of dollars each year on pre border, border and post border biosecurity programs. While the resourcing of some of these programs is determined by existing deeds of agreement, others, particularly in relation to environmental and social pests and diseases, fall outside of existing decision frameworks. This paper presents a new biosecurity investment decision framework based on economic principles that aims to produce more objectively determined decisions. It determines whether a role for government exists in relation to a specific problem through the application of market failure tests and then guides the user to the most efficient cost recovery mechanism. The framework is presently under active consideration for use by Industry & Investment NSW and would be suitable for wider application.Biosecurity, investment decision framework, biosecurity policy, market failure test, cost recovery, Environmental Economics and Policy,

Industry structure and regulation

As private firms become increasingly involved in the development of key infrastructure, redefining the role of government from that of serviceprovider to regulator presents both challenges and opportunities. The factors that give rise to sector reforms color how much policymakers invest in regulatory design during the reform process. Nevertheless, two factors are essential to sustainable sector and regulatory reform. First, the right structure must be established for the industry concerned, a structure that allows competition appropriate for that industry. Second, the objectives of regulation must be well defined, with a clear distinction between policymaking, policy implementation, and operations. The extent to which competition can be harnessed to help make regulation efficient, effective, and sustainable depends on the intrinsic technical characteristics of the sector. Each decision affects the sustainability of the regulatory regime in the face of the threat of regulatory capture (both political and commercial). Careful regulatory design is crucial not only for successful sectoral reform but also to balance the interests of various actors (government, consumers, developers, investors, and financiers). One model that has been relatively successful combines new entry, unbundled services, and the unambiguous spelling out of the legal rights and duties for both public and private service providers, administered by an autonomous regulatory authority. Problems with regulation often result as much from inadequate attention to sector structure and fostering competition as from weaknesses in the regulatory authority's institutional capacity. As for the tools of regulation, despite differences in some details between licenses and concessions (and their many contractual variations), these are basically instruments that establish the rights and obligations of contracting parties. Choices about where these rights and obligations are located in the legal hierarchy are shaped by a country's institutional capacity and legal traditions. But the existence of instruments to establish those rights and obligations does not eliminate the need for institutionsto administer them, and thus carry out the regulatory function. Establishing effective sectorwide regulation can be difficult in a developing country, but it is necessary. Policymakers will be able to create effective regulatory regimes where adequate attention is given to sector structure, competition, and institution-building.Environmental Economics&Policies,Trade Finance and Investment,Knowledge Economy,ICT Policy and Strategies,Decentralization,Environmental Economics&Policies,Administrative&Regulatory Law,ICT Policy and Strategies,Water and Industry,Knowledge Economy

Equal remuneration under the Fair Work Act 2009

The Commission’s Pay Equity Unit commissioned this research report to: assist parties to equal remuneration proceedings under Part 2-7 to engage in productive discussion and work towards greater consensus in relation to the proceedings; and inform potential parties about the matters they might be required to address and the type of evidence they might be required to bring as part of an equal remuneration proceeding. The report responds to those objectives in the following structure: setting the global scene, by describing the international labour standards on equal remuneration, providing international data on the GPG and summarising key elements of the approaches taken in selected overseas jurisdictions analysing the treatment of equal remuneration under the Fair Work Act; outlining the SACS case and explaining the various decisions given by the Fair Work Commission and its predecessors  reviewing available literature on how the GPG might be explained and assessed; and drawing on the research undertaken for the above purposes, outlining approaches which might usefully guide the conduct of future proceedings under Part 2-7 of the Fair Work Act The report also includes three appendices. The first two detail the development of equal remuneration regulation at the federal level (Appendix A) and under the State industrial systems (Appendix B). The third, Appendix C, provides an overview of the approaches taken in the European Union and ten selected countries—Belgium, Canada, Ireland, Finland, the Netherlands, New Zealand, Norway, Sweden, the United Kingdom and the United States. The report is the product of independent research by the authors, and the views it contains are those of the authors, not of the staff or Members of the Fair Work Commission

An assessment of the mantle and slab components in the magmas of an oceanic arc volcano: Raoul Volcano, Kermadec arc

Raoul Volcano occupies a simple oceanic subduction setting in the northern part of the Kermadec arc on the Pacific–Australian convergent plate boundary. The primary inputs to the magmatic system that feeds the volcano are a subduction component derived from the subducting old Pacific oceanic lithosphere and its veneer of pelagic sediment, and the overlying peridotitic mantle wedge. Conservative trace elements that are very incompatible during mantle melting are relatively depleted in Raoul lavas indicating a source that has been depleted during an earlier melting event. Major element co-variations indicate magma genesis by 25% near fractional melting of a mantle source that is weakly depleted (2% melt extraction) relative to a fertile MORB source. An important influence on the composition of the mantle component is progressive melt extraction coupled with minimal advection of fresh material into the sub-arc zone followed by melt extraction from a melting column beneath the spreading centre of an adjacent back arc basin. High field strength element and rare earth element systematics indicate involvement of a subduction-related component of constant composition. Two fluid components can be distinguished, one enriched in large ion lithophile elements inferred to be an aqueous fluid that is continuously added to the ascending melt column and the other a less mobile fluid that transfers Th. A homogeneous subduction-related component of constant composition and magnitude arises if the slab-derived flux migrates from the slab–mantle interface to the sub-arc melting column by repeated episodes of amphibole formation and decomposition its composition is then governed by the distribution coefficients of pyroxene and its magnitude by the degree of amphibole saturation of mantle peridotite. The results from Raoul Volcano are comparable to those from other oceanic subduction-related arcs such as South Sandwich and Marianas suggesting that this is a general model for oceanic arcs

Ephedrine requirements are reduced during spinal anaesthesia for caesarean section in preeclampsia

Part of the Portfolio Thesis by Geoffrey H. Sharwood-Smith: The inferior vena caval compression theory of hypotension in obstetric spinal anaesthesia: studies in normal and preeclamptic pregnancy, a literature review and revision of fundamental concepts, available at http://hdl.handle.net/10023/1815Background: Despite controversy over the haemodynamically safest blockade for caesarean section in women with severe preeclampsia, an increasing number of anaesthetists now opt for spinal anaesthesia. In a previous study we found that spinal compared to epidural anaesthesia offered an equally safe but more effective option for these patients. The current study was designed to compare the hypotension induced by spinal anaesthesia, as measured by ephedrine requirement, between 20 normotensive and 20 severely preeclamptic but haemodynamically stabilised women. Method: Standardised spinal anaesthesia was instituted and ephedrine was given in boluses of 6 mg if the systolic pressure fell >20% from the baseline, or if the patient exhibited symptoms of hypotension. Results: The mean ephedrine requirement of the normotensive group (27.9 ± 11.6 mg) was significantly greater (P < 0.01) than that of the preeclamptic group (16.4 ± 15.0 mg). Conclusion: This suggests that the hypotension induced by spinal anaesthesia in women with severe but haemodynamically stabilised preeclampsia, is less than that of normotensive patients.Publisher PD

A reinterpretation of phase velocity data based on the gnome travel time curves

Significant lateral variations in upper mantle velocities across the western U. S. were observed in the GNOME experiment. This makes necessary a reinterpretation of crustal thickness measurements made with the assumption that velocities in the various layers of the crust remain constant while their thickness changes. Four examples of the work of Ewing and Press have been reinterpreted. The crust is thinner (30 km) in the Basin and Range Province and thicker (55 km) under the Rocky Mountains than indicated by previous interpretations
