Organic Food Subscription Schemes in Emerging Organic Markets: TEI-KEI, CSA and Box-Schemes

In this article the development of Organic Food Subscription Schemes beginning from the 70ies in Japan (TEI-KEI), the 80ies in North-America (CSA) and in 90ies in Europe (BOX- and BAG-SCHEMES) will be outlined. Furthmermore the Box-Scheme Development Modell will be discribed and important management issues will be discussed

Economic, Political, Institutional as well as Social Risks and Opportunities of EMU Enlargement

The inclusion on May 1st, 2004 of eight Central and Eastern European Countries (CEEC) into the European Union (EU), and subsequently into the European Monetary Union (EMU) some years later, will cause deep changes within the political, economic, and social settings of the Union as well as in those of the new member countries. This paper’s underlying idea is that the new EU members in Central and Eastern Europe should continue to pursue an economic strategy of real convergence to the economic levels of the "old" member countries as rapidly as possible by securing sustained growth, e.g. by increasing private savings and by reducing the current account deficit. This report will discuss the implications of a "catch-up" strategy and have a look at the economic, political, social and institutional consequences for EMU enlargement.

Biogenesis of mitochondrial ubiquinol

The precursor proteins to the subunits of ubiquinol:cytochrome c reductase (cytochrome bc1 complex) of Neurospora crassa were synthesized in a reticulocyte lysate. These precursors were immunoprecipitated with antibodies prepared against the individual subunits and compared to the mature subunits immunoprecipitated or isolated from mitochondria. Most subunits were synthesized as precursors with larger apparent molecular weights (subunits I, 51,500 versus 50,000; subunit II, 47,500 versus 45,000; subunit IV (cytochrome c1), 38,000 versus 31,000; subunit V (Fe-S protein), 28,000 versus 25,000; subunit VII, 12,000 versus 11,500; subunit VIII, 11,600 versus 11,200). Subunit VI (14,000) was synthesized with the same apparent molecular weight. The post-translational transfer of subunits I, IV, V, and VII was studied in an in vitro system employing reticulocyte lysate and isolated mitochondria. The transfer and proteolytic processing of these precursors was found to be dependent on the mitochondrial membrane potential. In the transfer of cytochrome c1, the proteolytic processing appears to take place in two separate steps via an intermediate both in vivo and in vitro. In vivo, the intermediate form accumulated when cells were kept at 8 degrees C and was chased into mature cytochrome c1 at 25 degrees C. Both processing steps were energy- dependent

Analysis of Self-Reported Walking for Transit in a Sprawling Urban Metropolitan Area in the Western U.S.

Walkability is associated with increased levels of physical activity and improved health and sustainability. The sprawling design of many metropolitan areas of the western U.S., such as Las Vegas, influences their walkability. The purpose of this study was to consider sprawl characteristics along with well-known correlates of walkability to determine what factors influence self-reported minutes of active transportation. Residents from four neighborhoods in the Las Vegas Metropolitan Area, targeted for their high and low walkability scores, were surveyed for their perceptions of street-connectivity, residential-density, land-use mix, and retail–floor-area ratio and sprawl characteristics including distance between crosswalks, single-entry-communities, high-speed streets, shade, and access to transit. A Poisson model provided the best estimates for minutes of active transportation and explained 11.28% of the variance. The model that included sprawl characteristics resulted in a better estimate of minutes of active transportation compared to the model without them. The results indicate that increasing walkability in urban areas such as Las Vegas requires an explicit consideration of its sprawl characteristics. Not taking such design characteristics into account may result in the underestimation of the influence of sprawl on active transportation and may result in a missed opportunity to increase walking. Understanding the correlates of walkability at the local level is important in successfully promoting walking as a means to increase active transportation and improve community health and sustainability
