Crop protection,what will shape the future picture?,

PEST MANAGEMENT SCIENCE (FORMERLY: PESTICIDE SCIENCE), Issue 2 2004
David Atkinson
Abstract The drivers which influence the types of crop protection most needed by agriculture are changing. A polarisation of approaches has resulted in the needs of organic agriculture and biotechnological agriculture, which can be identified as the current extremes of the spectrum, becoming very different. The main requirements of these two sectors are identified here and used as the basis for questioning future EU research requirements in crop protection. Factors affecting/influencing organic farming and the use of genetically modified crops are discussed in some detail. Copyright © 2004 Society of Chemical Industry [source]


Recent developments in gravity-wave effects in climate models and the global distribution of gravity-wave momentum flux from observations and models

THE QUARTERLY JOURNAL OF THE ROYAL METEOROLOGICAL SOCIETY, Issue 650 2010
M. J. Alexander
Abstract Recent observational and theoretical studies of the global properties of small-scale atmospheric gravity waves have highlighted the global effects of these waves on the circulation from the surface to the middle atmosphere. The effects of gravity waves on the large-scale circulation have long been treated via parametrizations in both climate and weather-forecasting applications. In these parametrizations, key parameters describe the global distributions of gravity-wave momentum flux, wavelengths and frequencies. Until recently, global observations could not define the required parameters because the waves are small in scale and intermittent in occurrence. Recent satellite and other global datasets with improved resolution, along with innovative analysis methods, are now providing constraints for the parametrizations that can improve the treatment of these waves in climate-prediction models. Research using very-high-resolution global models has also recently demonstrated the capability to resolve gravity waves and their circulation effects, and when tested against observations these models show some very realistic properties. Here we review recent studies on gravity-wave effects in stratosphere-resolving climate models, recent observations and analysis methods that reveal global patterns in gravity-wave momentum fluxes and results of very-high-resolution model studies, and we outline some future research requirements to improve the treatment of these waves in climate simulations.

The problems of sustainable water use in the Mediterranean and research requirements for agriculture

ANNALS OF APPLIED BIOLOGY, Issue 3 2004
J LARAUS
Summary This study addresses the sustainable use of water resources in the Mediterranean basin, particularly in the Southern and Eastern parts of the region, and the many problems generated by water scarcity and misuse. Water economy in the region is beset by two specific problems: high irrigation needs and changes in consumer demands (especially after population shifts from rural to urban areas and because of increasing tourism and industrialisation). The challenges presented by the water crisis are even greater because of growing populations and estimated future climatic changes in the region. The integrated management of limited water resources in the Southern and Eastern parts of the Mediterranean involves several areas of research. Those most directly related with agriculture concern improving water (and nutrient) use in agriculture through the management and breeding of irrigated and rain-fed crops. However, these fields of research address only one face of a multi-factorial equation that affects water sustainability in the region. Thus, other research fields include the design of comprehensive water policies and integrated planning, and technologies for advanced water treatment and re-use. Moreover, local problems and socio-economic aspects must be considered when addressing research issues. [source]


Occurrence of killer whales in Scottish inshore waters: temporal and spatial patterns relative to the distribution of declining harbour seal populations

AQUATIC CONSERVATION: MARINE AND FRESHWATER ECOSYSTEMS, Issue 6 2009
Harriet E. Bolt
Abstract 1.Sightings of killer whales around Shetland were recorded between 1991 and 2006 and for the whole of Scotland for 2007. The data were used to investigate temporal patterns in killer whale occurrence around Shetland and spatial patterns in occurrence around Scotland. 2.There was a strong seasonal peak in sightings around Shetland during June,July, coinciding with the harbour seal pupping season. 3.There was no clear trend in annual sightings around Shetland between 1991 and 2006. 4.Killer whales were sighted most frequently around Shetland and the Pentland Firth as well as around Mull and the Treshnish Isles. 5.These findings are discussed in terms of potential impacts upon local declining harbour seal populations and future research requirements.

The Consent and Prescription Compliance (COPRECO) Study: Does Obtaining Consent in the Emergency Department Affect Study Results in a Telephone Follow-up Study of Medication Compliance?

ACADEMIC EMERGENCY MEDICINE, Issue 10 2008
CCFP(EM), Samuel G. Campbell MB BCh
Abstract Objectives:, The objectives were to determine whether mandated research requirements for consent in the emergency department (ED) falsely distorts the results of a survey of patient-reported compliance with ED prescriptions and, in addition, to ascertain the level of patient compliance to medication instructions and find out the degree of displeasure expressed by patients called without prior consent. Methods:, Patients given new prescriptions for a medicine to be taken regularly over a period of less than 30 days were eligible. A convenience sample of eligible patients was randomized to having consent obtained during their ED visit or at the time of telephone follow-up. Patients were called 7,10 days after their ED visit to determine their compliance with the prescription. Compliance rates between the two groups were compared, as was the prevalence of displeasure expressed by patients called without prior consent. Results:, Of 430 enrolled patients, 221 were randomized to receive ED consent for telephone follow-up, and 209 received telephone follow-up without prior ED consent. Telephone follow-up was successful in 318 patients (74%). The rate of noncompliance was slightly higher in the group without ED consent, 74/149 (50%; 95% confidence interval [CI] = 41% to 58%) than the group who gave ED consent for telephone follow-up, 67/169 (40%; 95% CI = 32% to 42%; p = 0.07). Among the two groups, 141/318 (44%) did not fill the prescription (n = 42) or took it incorrectly (n = 99). Only 1 (0.7%) of the 149 patients with successful telephone follow-up without prior ED consent expressed displeasure at this telephone call. Conclusions:, Medicine noncompliance is a significant issue for patients discharged from the ED in this study. Although there was a trend toward greater compliance in patients who consented to the follow-up call, this did not reach statistical significance. ED patients do not object to receiving telephone follow-up for a research survey without giving prior consent. [source]
