Selected AbstractsHousehold demand analysis of organic and conventional fluid milk in the United States based on the 2004 Nielsen Homescan panelAGRIBUSINESS : AN INTERNATIONAL JOURNAL, Issue 3 2010Pedro A. Alviola IV Using the 2004 AC Nielsen panel consisting of over 38,000 households, the authors ascertain the influence of selected demographic variables associated with the purchase of organic fluid milk through the estimation of a probit model. From the use of the Heckman two-step procedure, they also calculate own-price, cross-price, and income elasticities by estimating demand relationships for both organic and conventional milk. They find that demographic factors play a crucial role in the household choice of purchasing organic milk. Furthermore, households are more sensitive to own-price changes in the case of organic milk versus conventional milk. Evidence from estimated cross-price elasticities indicates that organic and conventional milk are substitutes. However, quantities purchased of organic milk are more sensitive to changes in prices of conventional milk than vice versa. Consequently, an asymmetric pattern exists with regard to the substitution patterns of the respective milk types. Moreover, evidence indicates that organic milk is responsive to income changes, but conventional milk is not responsive to income changes. Finally, a 1% increase in the price of organic milk reduces total milk sales by 0.20%, but a 1% increase in the price of conventional milk raises total milk sales by 0.31%.

[source] A Delphi survey of evidence-based nursing priorities in Hong KongJOURNAL OF NURSING MANAGEMENT, Issue 5 2002C PSYCHOL, Peter French PhD The purpose of this study was to inform an evidence-based nursing development project within the Hospital Authority, Hong Kong. It considered the specific question of: what are the nursing practice issues which need to be addressed as a matter of priority in order to improve nursing practice, the quality of care or develop some aspect of nursing practice. A three round Delphi survey was adopted. The methodological problems associated with the use of the Delphi method are addressed. An expert panel consisting of 190 Department Operations Managers (nurses) was identified. The data collection focused on issues related to nursing skills and client care and excluded management or educational issues. Agreed categories were prioritized in the final round by utilizing a 11-point rating scale. The group mean score for each category was calculated and rank ordered. The results provided 45 categories that reflected the nursing practice priorities that required more research evidence to guide practice. The top five ranked items were: nurse patient communication, resuscitation, administration of medicines, counselling and nursing documentation. The top 10 items were used to inform the advisory and selection processes for the evidence-based practice development project. [source] Foetal brain imaging: ultrasound or MRI.ACTA PAEDIATRICA, Issue 4 2008A comparison between magnetic resonance imaging, a dedicated multidisciplinary neurosonographic opinion Objectives: (i) To compare original foetal brain ultrasound findings with a multidisciplinary expert opinion; (ii) to compare the multidisciplinary expert ultrasound opinion with foetal magnetic resonance imaging (MRI) findings and (iii) to determine in which circumstances foetal MRI gives additional information, and in how many cases management is changed by having information from MRI. Study design: Ultrasound scans of 51 consecutive foetuses where foetal brain MR had been performed were retrospectively reviewed by a panel consisting of maternal-foetal-medicine (MFM) consultants, a geneticist, neonatologists and MFM subspecialty trainees. The original ultrasound opinion was compared with the multidisciplinary opinion, which was then compared with MRI findings. In the cases where MRI gave additional information, an assessment was made as to whether this changed management. Results: The multidisciplinary ultrasound opinion differed from the original opinion in 9 of 51 (17%) cases. In 19 patients (37%), the MRI gave additional information to the original ultrasound, in 7 (13%) cases, management, and in 7 (13%) cases, counselling was altered by additional information gained from MRI. The multidisciplinary ultrasound and MRI diagnoses were similar in 36 cases (71%). Conclusion: Multidisciplinary review of an apparently abnormal foetal brain ultrasound can provide additional diagnostic information. When compared with this level of ultrasound expertise, MRI gave additional information in 29% of cases, but only resulted in change in management in about 13%.

Banhart Abstract Sandwich panels consisting of a highly porous aluminium foam core and aluminium alloy face sheets are manufactured by roll-bonding aluminium alloy sheets to a densified mixture of metal powders , usually Al-Si or Al-Si-Cu alloys with 6,8% Si and 3,10% Cu , and titanium hydride, and foaming the resulting three-layer structure by a thermal treatment. We review the various processing steps of aluminium foam sandwich (AFS) and the metallurgical processes during foaming, compare the process to alternative ways to manufacture AFS, e.g. by adhesive bonding, and give an overview of the available literature. Two ways to treat AFS after foaming are presented, namely forging and age-hardening. Some current and potential applications are described and the market potential of AFS is assessed. [source] Prevalence of tick-borne encephalitis virus in Ixodes ricinus ticks in FinlandJOURNAL OF MEDICAL VIROLOGY, Issue 1 2001Xiuqi Han Abstract Approximately 20 cases of tick-borne encephalitis (TBE) occur annually in Finland. The known endemic areas are situated mainly in the archipelago and coastal regions of Finland, with highest incidence in Åland islands. Ixodes ricinus panels collected in 1996,1997 from two endemic areas were screened for the presence of RNA. Two distinct RT-PCR methods were applied, and were shown to have an approximate detection limit of 10 focus forming doses (FFD)/100 ,l. One out of 20 pools (a total of 139 ticks) from Helsinki Isosaari Island and one out of 48 pools (a total of 450 ticks) from Åland were positive with both methods, whereas the remaining pools were negative. The observed overall frequency (0.34%) in ticks in endemic areas of Finland, was similar to the low incidence found by virus isolation in mice in the 1960s (0.5%). Viral RNA was detectable in a diluted sample representing 0.005% of a positive pool of ten nymphs suggesting that the viral RNA load within an infected tick pool was approximately equivalent to 20,000,200,000 FFD. Sequence analysis did not show geographical clustering of the Finnish strains, suggesting an independent emergence of different TBE foci from the south. TBE virus RNA positive ticks were not found in I. ricinus panels consisting of 130 pools (726 ticks) from Helsinki city parks or 41 pools (197 ticks) from Võrmsi Island in Estonia. J. Med.
