A Cross Country Comparison of the Development of the Organic Sector in Denmark, Germany, United Kingdom and the Netherlands
The aim of this article is to test the thesis "commitment of retail chains as well as favourable policy conditions are the main drivers of the steady market growth of organic agriculture in Europe." (Yussefi and Willer, 2003). Therefore, the role of government policy and of retail chains in four European countries - Denmark, Germany, the United Kingdom and the Netherlands - are analysed. It seems that the collaboration between government, chain participants and NGOs is of considerable importance, in which active stimulation and the provision of guidance to the channel from the retail chains, in combination with an active and stimulating government policy, can cause an impulse in growth. It should be noted that other factors must also be present in order for market players to convert; likewise, consumer demand should be well developed.Farm Management,

The Heroic Image: The Lives and Times of Superstars in Two Golden Ages of Sport
If the Summer Olympics of 1984 or the yearly Super Bowl extravaganzas are any indication, Americans continue to be sports-obsessed. It has become increasingly important that we reflect about professional athletes and the public\u27s perception of their role in society. I would like to take a subjective, biographical look at four dominant athletes who influenced American civilization during our two Golden Ages of Sport, namely, the 1920s and the late 1960s-1970s
Faster magnetic resonance imaging in emergency room patients with right lower quadrant pain and suspected acute appendicitis
Purpose: Emergency Departments (ED) are becoming busier, with a resultant increase in the number of imaging referrals. The purpose of this study was to assess the diagnostic accuracy of an abbreviated two sequence magnetic resonance (MR) protocol for evaluating ED patients with right lower quadrant pain and suspected acute appendicitis, with a view to expediting patient turnaround times and imaging costs. Material and methods: Fifty patients (49 females, one male; mean age 25.4 ± 5.2 years) who underwent ED MR imaging from July 2014 to March 2015 for right lower quadrant pain were retrospectively reviewed. MR abdomen/pelvis was performed on 1.5 T MR obtaining axial T1 gradient echo in/out of phase, transverse fast spin echo T2 with fat sat/motion correction, axial/coronal T2 HASTE (half-Fourier acquisition single-shot turbo spin-echo), and axial DWI (diffusion-weighted imaging) sequences. Images were reviewed by two fellowship-trained radiologists on a five-point confidence scale. Mean acquisition/interpretation times for the standard departmental protocol and the proposed abbreviated MR protocol (comprising T2 HASTE and DWI images) were calculated. Sensitivity, specificity, and diagnostic accuracy for the abbreviated protocol against the full protocol were also calculated. Results: Mean scanning time for abbreviated protocol and standard protocol was calculated to be 21.1 minutes and 40.5 minutes, respectively. Mean interpretation time for abbreviated protocol for reader one and two was 4.1 ± 1.5 minutes and 4.5 ± 1.4 minutes, respectively, and for standard protocol was 8.1 ± 1.8 minutes and 7.1 ± 1.4 minutes, respectively. Sensitivity, specificity, and accuracy for the FAST protocol were calculated to be 100% each for reader one and 75%, 100%, and 94%, respectively, for reader two. Conclusions: The proposed abbreviated MR protocol has comparable diagnostic accuracy in diagnosing ED patients with right lower quadrant pain, with significant reduction in imaging/interpretation times. It thus has the potential to be implemented in ED imaging with significant reduction in patient turnaround times and costs
