Organic conversion strategies for stockless farming systems

This report was presented at the UK Organic Research 2002 Conference. The identification of appropriate stockless organic conversion strategies will help farmers and growers in their decision to convert to organic production. The current practice of a two-year red clover/ryegrass ley conversion relies on subsidies to be economically viable. This standard conversion and six alternatives were tested on a sandy loam soil entering organic conversion. A test crop of winter wheat will be grown across the entire experimental area in the first fully organic year (2001/2002). Strategies containing a legume ley phase returned the greatest amount of nitrogen to the soil. At the end of the second year, pre-cultivation, there were no differences in soil mineral nitrogen between strategies. Gross margins were greater from those strategies with cash cropping than those without, in spite of the generally depressed yields. Preliminary analysis suggests that growing red clover for seed in year 1 followed by a red clover ley in year 2 could be the most profitable option

Market returns and mutual fund flows

With the increased popularity of mutual funds come increased concerns. Namely, could a sharp drop in stock and bond prices set off a cascade of redemptions by mutual fund investors and could the redemptions exert further downward pressure on asset markets? The authors analyze this relationship by using instrumental variables--a measuring technique previously unapplied to market returns and mutual fund flows--to determine the effect of returns on flows. Despite market observers' fears of a downward spiral in asset prices, the authors conclude that the short-term effect of market returns on mutual fund flows typically has been too weak to sustain such a spiral.Mutual funds ; Stock - Prices

Technology Transfer in the Irish Food Industry: Researcher Perspectives

The public R&D system represents an important part of the framework conditions for carrying out innovation activities and creating commercially applicable knowledge (Drejer and Jørgensen, 2004). It is an important source of information for companies, particularly those that are developing new products (Tijssen, 2004). However, Rubenstein (2003) stated that there has been a perception that public research capacity and results were not being optimally used and thus that potential economic benefits were not entirely realised. It is also suggested that research conducted in the public sector is not efficiently or successfully transferred to industry (Markman et al, 1999) and that it is necessary to understand and improve the means of technology transfer for society to reap the benefits of public science (Geuna and Nesta, 2003). Thus, there is a growing interest, and indeed pressure, among policymakers and academics to ensure informed spending of taxpayers’ money, that useful and relevant research is conducted that represents good “value for money” and that wealth is generated from publicly-funded research (Carr, 1992; Lyall et al., 2004; Mustar et al., 2006). To achieve this requires, amongst other things, the establishment of scientific and technical human capital which is the sum of researchers’ professional network ties and their technical skills and resources (Bozeman and Coreley, 2004). This paper examines the interactions engaged in by researchers from Irish public science providers (public research centres and higher education institutions), with a particular focus on researchers- industry interactions, as well as their skills and resources. To provide context, it firstly briefly outlines the actors involved in conducting publicly funded R&D in Ireland. It then describes the methodology and presents the results of a national survey of publicly funded food researchers focusing on the extent and nature of researcher interactions with other researchers and with industry, the barriers to and motivations for researcher-industry interaction and researcher skills regarding technology transfer. It concludes with a discussion and some policy recommendations.Agribusiness, Agricultural and Food Policy, Farm Management, Food Consumption/Nutrition/Food Safety, Industrial Organization,

Knowledge Transfer in the Irish Food Innovation System: Industry and Researcher Perspectives

The new EU Animal Health Strategy suggests a shift in emphasis away from control towards prevention and surveillance activities for the management of threats to animal health. The optimal combination of these actions will differ among diseases and depend on largely unknown and uncertain costs and benefits. This paper reports an empirical investigation of this issue for the case of Avian Influenza. The results suggest that the optimal combination of actions will be dependent on the objective of the decision maker and that conflict exists between an optimal strategy which minimises costs to the government and one which maximises producer profits or minimises negative effects on human health. From the perspective of minimising the effects on human health, prevention appears preferable to cure but the case is less clear for other objectives.Knowledge transfer, technology transfer, Irish food sector, Research and Development/Tech Change/Emerging Technologies,

The emergence of proton nuclear magnetic resonance metabolomics in the cardiovascular arena as viewed from a clinical perspective

The ability to phenotype metabolic profiles in serum has increased substantially in recent years with the advent of metabolomics. Metabolomics is the study of the metabolome, defined as those molecules with an atomic mass less than 1.5 kDa. There are two main metabolomics methods: mass spectrometry (MS) and proton nuclear magnetic resonance (1H NMR) spectroscopy, each with its respective benefits and limitations. MS has greater sensitivity and so can detect many more metabolites. However, its cost (especially when heavy labelled internal standards are required for absolute quantitation) and quality control is sub-optimal for large cohorts. 1H NMR is less sensitive but sample preparation is generally faster and analysis times shorter, resulting in markedly lower analysis costs. 1H NMR is robust, reproducible and can provide absolute quantitation of many metabolites. Of particular relevance to cardio-metabolic disease is the ability of 1H NMR to provide detailed quantitative data on amino acids, fatty acids and other metabolites as well as lipoprotein subparticle concentrations and size. Early epidemiological studies suggest promise, however, this is an emerging field and more data is required before we can determine the clinical utility of these measures to improve disease prediction and treatment. This review describes the theoretical basis of 1H NMR; compares MS and 1H NMR and provides a tabular overview of recent 1H NMR-based research findings in the atherosclerosis field, describing the design and scope of studies conducted to date. 1H NMR metabolomics-CVD related research is emerging, however further large, robustly conducted prospective, genetic and intervention studies are needed to advance research on CVD risk prediction and to identify causal pathways amenable to intervention

Exploratory study of language paediatricians use to promote adherence to long-term controller medication in children with asthma

Introduction and objectives: Although patient centred communication is associated with patients’ daily medication adherence, the exact communication phenomena promoting high treatment adherence remain elusive. Patients and methods: We used conversation analysis of videotaped follow-up consultations of seven outpatients (4–13 years of age) with chronic asthma and their caregivers, consulting two paediatric respiratory physicians in a practice in which high treatment adherence has been documented, to explore the language paediatricians use to promote their patients’ adherence to daily controller medication. Results: Starting the consultation with the patient's (and caregivers’) agenda commonly resulted in presentation of issues new to the physician. Information was mostly provided in response to patient/caregiver questions, prompting the delivery of specific information tailored to the patient's and caregivers’ needs. Although patients and caregivers showed resistance in response to unsolicited information and advice, they always accepted the doctor's explicit request for agreement with proposed treatment. The doctor's description of favourable treatment results in most patients prompted caregivers’ willingness to accept treatment proposals. Conclusions: Paediatricians with a documented success in achieving adherence to controller medication in their patients with asthma tend to start consultations with the patient's agenda, provide information in response to questions, offer reassurance on overall treatment effectiveness, and seek explicit agreement with a treatment proposal
