The demise of the USSR led to the collapse of its centrally organised retail system. With this collapse the supply of consumer goods dried up, especially in the remote parts of the former USSR. At the same time the advent of capitalism offered a new institutional framework for independent retail activities. In the Kyrgyz Republic, where the economic liberalisation followed strictly the Washington Consensus, a large number of small shops emerged in both urban and rural areas. This study analyses the reasons for this boom in retail start-ups as well as the constraints the mainly inexperienced merchants encounter. As will be shown, any success in retail activities depends greatly on the performance of other economic sectors. The main goal of starting a retail business is to minimize risks within the overall livelihood strategies of households in rural Kyrgyzstan.  相似文献

This article traces the creation and demise of the U.S. Advisory Commission on Intergovernmental Relations (ACIR) and assesses the prospects for restoring an ACIR‐like capability to the federal system. Recent initiatives by the National Academy of Public Administration, the Big 7 state and local government official associations, and Congress are summarized, and the facilitating and inhibiting factors associated with intergovernmental institutional development are examined. At least three ingredients in the formula that gave birth to the ACIR in 1959 will need to be present more than 50 years later: (1) support from congressional champions, the president, and public interest groups; (2) visibility and urgency of intergovernmental fiscal and management issues and the need for a permanent intergovernmental presence to address them; and (3) “homework and spadework” to enlist potential conservative and liberal interest group and think tank backers.  相似文献

Abstract: Recently a small sampled cadaver study (n = 4) suggested that the human eyeballs are placed closer to the orbital roof and lateral orbital wall as first reported in the anatomical literature many years previously. This contrasts with central positioning of the eyeball within the orbit as advocated by the facial approximation literature. Given the limits of such small samples, this study re-examined globe position in nine new cadavers to help clarify which relationship is accurate. The results essentially confirm prior empirical findings except that the mean lateral divergences from the orbit center were found to be larger—the eyeball was found to be “displaced” 1.4 mm superiorly and 2.4 mm laterally. Medians calculated across all 13 cadavers from this study and the above-mentioned recent report refine these measurements to 1.4 and 2.3 mm respectively. Globe projection values were identical to those observed for living individuals (c. 16 mm).  相似文献

The present 4-year follow-up study involves 56 mothers who were evaluated by social agencies as being abusive and neglectful or at high risk for child abuse and neglect. The aim of the study is to analyze the relationship between psychosocial risk factors (relating to the history and current situation of the mothers) that were present at the time the families were initially recruited and the fact that some of the mothers continue to show a high potential for child abuse and neglect (chronic abuse and neglect), whereas others were able to overcome the problem (transitory abuse and neglect). Results indicate that the following variables are particularly associated with situations involving chronic problems of abuse and neglect: initial level of severity of potential for abuse and neglect; dual-parent status; a large number of children at the time of intervention (3.13 times more risk of chronicity for large families); the fact that as a child the mother herself had been placed in a foster home (3.7 times more risk); that she had been sexually abused (3.5 times more risk); and that as an adolescent she had run away from home (3.02 times more risk). Our results indicate that mothers who have a combination of more than eight risk factors are four times more likely to be in the chronic group.  相似文献
