Évaluation du potentiel de croissance et de rendement d’une culture de tomates biologiques cultivées dans une serre climatisée à l’aide d’un système géothermique

Ce projet visait à comparer les effets agronomiques d’une serre de tomates biologiques semi-fermée utilisant un système de climatisation par géothermie comparativement à une serre ouverte. Deux serres de 228 et 230 m2 ont été équipées d’un système d’échangeur d’air avec géothermie qui refroidissait et déshumidifiait l’air (serre semi-fermée) et d’un système de ventilation naturelle (serre témoin). Ces dernières ont été comparées au cours des années 2012 et 2013 entre lesquels les traitements ont été permutés. Les variables mesurées étaient les paramètres de croissance des plants ainsi que le rendement, le calibre des fruits et les propriétés physico-chimiques des tomates. Les résultats ont démontré que le système de climatisation n’a pas eu d’effets significatifs sur la croissance des plants, la qualité des fruits ainsi que le rendement. Les deux serres avaient des cibles de concentration en CO2 comprises entre 450 µL L-1 et 1000 µL L-1 selon l’ensoleillement. Les quantités de CO2 injectées ont été de 11 kg/m2 et 15 kg/m2 respectivement en 2012 et 2013 dans la serre semi-fermée alors qu’elles ont été de 24 kg/m2 et 25 kg/m2 dans la serre témoin. Bien qu’ayant nécessité moins d’injection, la serre semi-fermée a permis de conserver des concentrations en CO2 de 638 µL L-1 en 2012 et de 593 µL L-1 en 2013. Ces concentrations sont plus élevées que celles obtenues dans la serre témoin qui étaient respectivement de 385 µL L-1 et 486 µL L-1 en 2012 et 2013. De ce fait, le coût monétaire associé à l’enrichissement carboné a été de 1,6 à 2,0 fois plus élevé dans la serre témoin que dans la serre semi-fermée.

Évaluation pharmacoéconomique d'un test de prédisposition génétique aux effets secondaires musculaires reliés aux statines

Introduction : Les statines ont prouvé leur efficacité dans le traitement des dyslipidémies. Cependant, ces molécules sont associées à des effets secondaires d’ordre musculaire. Puisque ces effets peuvent avoir des conséquences graves sur la vie des patients en plus d’être possiblement à l’origine de la non-observance d’une proportion importante des patients recevant une statine, un outil pharmacogénomique qui permettrait d’identifier a priori les patients susceptibles de développer des effets secondaires musculaires induits par une statine (ESMIS) serait très utile. L’objectif de la présente étude était donc de déterminer la valeur monétaire d’un tel type d’outil étant donné que cet aspect représenterait une composante importante pour sa commercialisation et son implantation dans la pratique médicale courante. Méthode : Une première simulation fut effectuée à l’aide de la méthode de Markov, mais celle-ci ne permettait pas de tenir compte de tous les éléments désirés. C’est pourquoi la méthode de simulation d'évènements discrets fut utilisée pour étudier une population de 100 000 patients hypothétiques nouvellement initiés sur une statine. Cette population virtuelle a été dupliquée pour obtenir deux cohortes de patients identiques. Une cohorte recevait le test et un traitement approprié alors que l'autre cohorte recevait le traitement standard actuel—i.e., une statine. Le modèle de simulation a permis de faire évoluer les deux cohortes sur une période de 15 ans en tenant compte du risque de maladies cardio-vasculaires (MCV) fatal ou non-fatal, d'ESMIS et de mortalité provenant d’une autre cause que d’une MCV. Les conséquences encourues (MCV, ESMIS, mortalité) par ces deux populations et les coûts associés furent ensuite comparés. Finalement, l’expérience fut répétée à 25 reprises pour évaluer la stabilité des résultats et diverses analyses de sensibilité ont été effectuées. Résultats : La différence moyenne des coûts en traitement des MCV et des ESMIS, en perte de capital humain et en médicament était de 28,89 $ entre les deux cohortes pour la durée totale de l’expérimentation (15 ans). Les coûts étant plus élevés chez celle qui n’était pas soumise au test. Toutefois, l’écart-type à la moyenne était considérable (416,22 $) remettant en question la validité de l’estimation monétaire du test pharmacogénomique. De plus, cette valeur était fortement influencée par la proportion de patients prédisposés aux ESMIS, par l’efficacité et le coût des agents hypolipidémiants alternatifs ainsi que par les coûts des traitements des ESMIS et de la valeur attribuée à un mois de vie supplémentaire. Conclusion : Ces résultats suggèrent qu’un test de prédisposition génétique aux ESMIS aurait une valeur d’environ 30 $ chez des patients s’apprêtant à commencer un traitement à base de statine. Toutefois, l’incertitude entourant la valeur obtenue est très importante et plusieurs variables dont les données réelles ne sont pas disponibles dans la littérature ont une influence importante sur la valeur. La valeur réelle de cet outil génétique ne pourra donc être déterminée seulement lorsque le modèle sera mis à jour avec des données plus précises sur la prévalence des ESMIS et leur impact sur l’observance au traitement puis analysé avec un plus grand nombre de patients.

Evaluation of valuation of noise amelioration treatments within and outside the road reserve

In urban environments road traffic volumes are increasing and the density of living is becoming higher. As a consequence the urban community is being exposed to increasing levels of road traffic noise. It is also evident that the noise reduction potential of within-the-road-reserve treatments such as noise barriers, mounding and pavement surfacing has been exhausted. This paper presents a strategy that involves the comparison of noise ameliorative treatments both within and outside the road reserve. The noise reduction resulting from the within-the-road-reserve component of treatments has been evaluated using a leading application of the CoRTN Model, developed by the UK Department of Transport 1988 [1], and the outside road reserve treatment has been evaluated in accordance with the Australian Standard 3671, Acoustics – Road traffic noise intrusion – Building sitting and construction [5]. The evaluation of noise treatments has been undertaken using a decision support tool (DST) currently being developed under the research program conducted at RMIT University and Department of Main Roads, Queensland. The case study has been based on data from a real project in Queensland, Australia. The research described here was carried out by the Australian Cooperative Research Centre for Construction Innovation [9], in collaboration with Department of Main Roads, Queensland, Department of Public Works, Queensland, Arup Pty. Ltd., Queensland University of technology and RMIT University.

Current rural valuation practice : a survey of valuers and agribusiness managers on farm management and sustainable rural land use

Over the past 20 years the nature of rural valuation practice has required most rural valuers to undertake studies in both agriculture (farm management) and valuation, especially if carrying out valuation work for financial institutions. The additional farm financial and management information obtained by rural valuers exceeds that level of information required to value commercial, retail and industrial by the capitalisation of net rent/profit valuation method and is very similar to the level of information required for the valuation of commercial and retail property by the Discounted Cash Flow valuation method. On this basis the valuers specialising in rural valuation practice have the necessary skills and information to value rural properties by an income valuation method, which can focus on the long term environmental and economic sustainability of the property being valued. This paper will review the results of an extensive survey carried out by rural property valuers in Australia, in relation to the impact of farm management on rural property values and sustainable rural land use. A particular focus of the research relates to the increased awareness of the problems of rural land degradation in Australia and the subsequent impact such problems have on the productivity of rural land. These problems of sustainable land use have resulted in the need to develop an approach to rural valuation practice that allows the valuer to factor the past management practices on the subject rural property into the actual valuation figure. An analysis of the past farm management and the inclusion of this data into the valuation methodology provides a much more reliable indication of farm sustainable economic value than the existing direct comparison valuation methodology.

Property and valuation education : an analysis of UWS property students from 1994 to 2006

The valuation and property is an evolving industry and the participants within the industry are also changing. This change is due to improved technology and construction, global nature of business today, professional standards, legal and accounting issues and environmental matters. Throughout this change in the property industry, there has also been significant change in the structure and content of tertiary property courses in Australia. Over the past thirteen years each first year cohort commencing study in the property program at the University of Western Sydney have been surveyed in relation to their background, reasons for course selection and job expectations. This paper will review this annual survey and the profile of all first year students who commenced their studies in the Bachelor of Business (Property) degree [formerly Bachelor of Commerce (Property Economics) and Bachelor of Commerce (Land Economy)] for years commencing 1994 to 2006. The paper will also provide a detailed analysis of the type of student entering the property industry and their exposure to the valuation and property sectors prior to commencing their studies.

Current rural valuation practice : a survey of NSW valuers and agribusiness managers

Despite the advances that have been made in relation to the valuation of Commercial, Industrial and retail property, there has not been the same progress in relation to the valuation of rural property. Although number of rural property valuations also require the valuer to carry out a full analysis of the economic performance of the farming operations, as well as the long term environmental viability of the farm, this information is rarely used to assess the value of the property, nor is it even used for a secondary valuation method. Over the past 20 years the nature of rural valuation practice has required most rural valuers to undertake studies in both agriculture (farm management) and valuation, especially if carrying out valuation work for financial institutions. The additional farm financial and management information obtained by rural valuers exceeds that level of information required to value commercial, retail and industrial by the capitalisation of net rent/profit valuation method and is very similar to the level of information required for the valuation of commercial and retail property by the Discounted Cash Flow valuation method. On this basis the valuers specialising in rural valuation practice have the necessary skills and information to value rural properties by an income valuation method. Although the direct comparison method of valuation has been sufficient in the past to value rural properties the future use of the method as the main valuation method is limited and valuers need to adopt an income valuation method as at least a secondary valuation method to overcome the problems associated with the use of direct comparison as the only rural property valuation method, especially in view of the impact that farm technical, financial and environmental .management can have on rural property values. This paper will review the results of an extensive survey carried out by rural property valuers and agribusiness managers in NSW, in relation to the impact of farm management on rural property values and rural property valuation practice.

The use of income valuation methods to value rural property

Despite the advances that have been made in relation to the valuation of commercial, industrial and retail property, there has not been the same progress in relation to the valuation of rural property. Although the majority of rural property valuations also require the valuer to carry out a full analysis of the economic performance of the farming operations, this information is rarely used to assess the value of the property, nor is it even used for a secondary valuation method. Over the past 20 years the nature of rural valuation practice has required rural valuers to undertake studies in both agriculture (farm management) and valuation, especially if carrying out valuation work for financial institutions.

This paper will review the results of an extensive survey carried out by rural property valuers in New South Wales (NSW), Australia, in relation to the impact of farm management on rural property values and rural property income potential.

Patient preference for falls prevention in hospitals revealed through willingness-to-pay, contingent valuation survey

Rationale, aims and objectives: Patient preference for interventions aimed at preventing in-hospital falls has not previously been investigated. This study aims to contrast the amount patients are willing to pay to prevent falls through six intervention approaches. ----- ----- Methods: This was a cross-sectional willingness-to-pay (WTP), contingent valuation survey conducted among hospital inpatients (n = 125) during their first week on a geriatric rehabilitation unit in Queensland, Australia. Contingent valuation scenarios were constructed for six falls prevention interventions: a falls consultation, an exercise programme, a face-to-face education programme, a booklet and video education programme, hip protectors and a targeted, multifactorial intervention programme. The benefit to participants in terms of reduction in risk of falls was held constant (30% risk reduction) within each scenario. ----- ----- Results: Participants valued the targeted, multifactorial intervention programme the highest [mean WTP (95% CI): $(AUD)268 ($240, $296)], followed by the falls consultation [$215 ($196, $234)], exercise [$174 ($156, $191)], face-to-face education [$164 ($146, $182)], hip protector [$74 ($62, $87)] and booklet and video education interventions [$68 ($57, $80)]. A ‘cost of provision’ bias was identified, which adversely affected the valuation of the booklet and video education intervention. ----- ----- Conclusion: There may be considerable indirect and intangible costs associated with interventions to prevent falls in hospitals that can substantially affect patient preferences. These costs could substantially influence the ability of these interventions to generate a net benefit in a cost–benefit analysis.

Valuation methods for resident funded retirement villages in Australia : a practitioner's perspective

Designed for independent living, retirement villages provide either detached or semi-detached residential dwellings with car parking and small private yards. Retirement village developments usually include a mix of independent living units (ILUs) and serviced apartments (SAs) with community facilities providing a shared congregational area for village activities and socialising. Retirement Village assets differ from traditional residential assets due to their operation in accordance with statutory legislation. In Australia, each State and Territory has its own Retirement Village Act and Regulations. In essence, the village operator provides the land and buildings to the residents who pay an amount on entry for the right of occupation. On departure from the units an agreed proportion of either the original purchase price or the sale price is paid to the outgoing resident. The market value of the operator’s interest in the Retirement Village is therefore based upon the estimated future income from Deferred Management Fees and Capital Gain upon roll-over receivable by the operator in accordance with the respective residency agreements. Given the lumpiness of these payments, there is general acceptance that the most appropriate approach to valuation is through Discounted Cash Flow (DCF) analysis. There is however inconsistency between valuers across Australia in how they undertake their DCF analysis, leading to differences in reported values and subsequent confusion among users of valuation services. To give guidance to valuers and enhance confidence from users of valuation services this paper investigates the five major elements of discounted cash flow methodology, namely cash flows, escalation factors, holding period, terminal value and discount rate. Whilst there is dissatisfaction with the financial structuring of the DMF in residency agreements, as long as there are future financial returns receivable by the Village owner/operator, then DCF will continue to be the most appropriate valuation methodology for resident funded retirement villages.

Implications of the National Rental Affordability Scheme on the valuation of residential property

The provision of shelter is a basic need and in Australia there has been a history of home ownership. However recent economic growth and rising construction costs, particularly over the past decade, has placed home ownership out of reach for some. In response to increased affordability pressures, the Australian Federal Government established the National Rental Affordability Scheme (NRAS) in 2008. The aim of establishing the NRAS initiative is to stimulate the supply of new affordable rental dwellings, targeting 50,000 new properties by June 2012, through the provision of a National Rental Incentive for each “approved” dwelling. To be approved the dwelling must be newly constructed and subsequently rented to eligible low and moderate income households at rentals no greater than 80 percent of market rates. There is a further requirement that the accommodation be provided as part of the scheme for no less than 10 years. The requirement to provide new residential accommodation at below market rentals for no less than 10 years has an impact on value and as such the valuation methodologies employed. To give guidance to valuers this paper investigates the scheme, the impact on value and expectations for the future.
