    Does the small business concern in this country have access to sufficient amounts of growth capital? For the past several years there has been much controversy concerning this question. Articles have been written both pro and con voicing opinions as to whether small businesses are being discriminated against in the acquisition of long-term loans to finance growth and business expansion. The majority of the written information on this subject appears to support the theory that too many small business firms are under-capitalized and the sources of long-term investment and growth funds are seriously limited to the small businessman

    Activity of Pursuit-Related Neurons in Medial Superior Temporal Area (MST) during Static Roll-Tilt

    Recent studies have shown that rhesus macaques can perceive visual motion direction in earth-centered coordinates as accurately as humans. We tested whether coordinate frames representing smooth pursuit and/or visual motion signals in medial superior temporal area (MST) are earth centered to better understand its role in coordinating smooth pursuit. In 2 Japanese macaques, we compared preferred directions (re monkeys' head–trunk axis) of pursuit and/or visual motion responses of MSTd neurons while upright and during static whole-body roll-tilt. In the majority (41/51 = 80%) of neurons tested, preferred directions of pursuit and/or visual motion responses were not significantly different while upright and during 40° static roll-tilt. Preferred directions of the remaining 20% of neurons (n = 10) were shifted beyond the range expected from ocular counter-rolling; the maximum shift was 14°, and the mean shift was 12°. These shifts, however, were still less than half of the expected shift if MST signals are coded in the earth-centered coordinates. Virtually, all tested neurons (44/46 = 96%) failed to exhibit a significant difference between resting discharge rate while upright and during static roll-tilt while fixating a stationary spot. These results suggest that smooth pursuit and/or visual motion signals of MST neurons are not coded in the earth-centered coordinates; our results favor the head- and/or trunk-centered coordinates

    Ottoman Merchants and Venetian Notaries in the Early Modern Period

    The aim of this paper is to study the presence of Ottoman merchants in Venice in the Modern Age. The Ottoman shipping partnership as well as the Venetian commenda were based on the mudarebe (classical Islamic shipping partnership) and several examples of this kind of partnerships may be found even between Christians and Muslims. Notarial deeds were above all proxies and often give information on merchants, their number and even their private life. Some of them were agents but there were also family companies and Ottoman grandees who were involved in international trade. Communities of merchants both in Istanbul and in Venice were also sometimes created. Last but not least, these sources contain also some examples of insurance made by Muslims to protect their goods. In general in the 16th and 17th centuries, the Ottoman merchants who traded in Venice were not alone, but they could refer to a real commercial network. Ancient historiographical theories say that in the Modern Age Ottoman Muslims were not interested in international trade and that they left it completely in Christian and Jewish hands, however documents tell us a completely different story, a story of contacts, exchanges, and even confidence and friendship

    There is no age limit for methadone: a retrospective cohort study

    BACKGROUND: Data from the US indicates that methadone-maintained populations are aging, with an increase of patients aged 50 or older. Data from European methadone populations is sparse. This retrospective cohort study sought to evaluate the age trends and related developments in the methadone population of Basel-City, Switzerland. METHODS: The study included methadone patients between April 1, 1995 and March 31, 2003. Anonymized data was taken from the methadone register of Basel-City. For analysis of age distributions, patient samples were split into four age categories from '20-29 years' to '50 years and over'. Cross-sectional comparisons were performed using patient samples of 1996 and 2003. RESULTS: Analysis showed a significant increase in older patients between 1996 and 2003 (p < 0.001). During that period, the percentage of patients aged 50 and over rose almost tenfold, while the proportion of patients aged under 30 dropped significantly from 52.8% to 12.3%. The average methadone dose (p < 0.001) and the 1-year retention rate (p < 0.001) also increased significantly. CONCLUSIONS: Findings point to clear trends in aging of methadone patients in Basel-City which are comparable, although less pronounced, to developments among US methadone populations. Many unanswered questions on medical, psychosocial and health economic consequences remain as the needs of older patients have not yet been evaluated extensively. However, older methadone patients, just as any other patients, should be accorded treatment appropriate to their medical condition and needs. Particular attention should be paid to adequate solutions for persons in need of care
