Conclusion It is necessary to strike the correct balance between safeguarding the rights of the individual and engendering mutually beneficial cooperation between states in extradition matters. In the absence of effective global international human rights enforcement mechanisms, many of the traditional safeguards still have a real role to play in extradition. This article reviewed five such safeguards and found that all but the nationality exception should be retained to ensure that international cooperation and individual protection are both safeguarded for the common good of society.This is a revised version of a paper presented at an international workshop on Principles and Procedures for a New Transnational Criminal Law, organized jointly by the Society for the Reform of Criminal Law and the Max Planck Institute for Foreign and International Criminal Law, Freiburg, Germany, May 21–25, 1991.LL.B., University of Exeter 1973; LL.M., Osgoode Hall Law School 1974; D.

On 31 December 1991, the Chinese State Council Housing System Reform Leading Group announced this Opinion, setting out targets, principles, and policies for the reform of the system of provisional housing in urban areas. Section 1 of the Opinion provides that the long-term goal of reform is to convert the distribution of housing from a system based on welfare allocation to one based on commodity exchange either by purchase or rental. Section 2 sets the following targets for reform: a) within the period of the Eighth Five-Year Plan, the system will be converted from one of low rent to one in which the calculation of rent will be based on cost of upkeep, administration costs, and depreciation; b) by 2000, the calculation of rent will be based on the above factors, as well as interest on investment and property taxes; and c) in the long term, the calculation of rent will be based on all of the above factors, as well as land rent, insurance premiums, and profit. Section 4 deals with policies for managing various problems such as rent increases and subsidies, sales of housing, financing for housing, the system of investment in and construction of housing, and administration of housing. This Section provides that a three-level housing investment fund based on municipalities, work units, and individuals will be established.  相似文献

A 1990 report prepared by the Office of Inspector General estimated that as much as $1 billion is lost to the Medicare program annually because (i) secondary payor situations are not detected and (ii) insurance companies often do not pay when they are required to be the primary payors. Office of Inspector General, No. A-09-98-00151, April 1990, Medicare and Medicaid Guide (CCH) [symbol: see text] 39,112, at 25,649. In order to better enforce the MSP provisions, suggestions have been made at the Congressional level to impose sanctions against providers who demonstrate a pattern of inappropriate billing practices such as double billing, repeated failures to screen beneficiaries for other insurance coverage, and the repeated submission to Medicare of bills that should be submitted to another payor. (See the Subcommittee Report on erroneous payments under the MSP program, supra.) Although authority for such sanctions has yet to be adopted, given the fiscal problems currently plaguing the federal government, providers can expect increased enforcement of the MSP provisions as a means of reducing Medicare costs, and should review their screening and billing practices accordingly.  相似文献

Many phenomena of interest to political scientists involve what may be termed impersonal influence; that is, influence that derives from individuals' perceptions of others' attitudes, beliefs, or experiences. Others in this case refers not to the close friends and acquaintances that concerned the authors of classics such asThe People's Choice andPersonal Influence, but rather to the anonymous others outside an individual's realm of personal contacts. Modern mass media facilitate the influence of anonymous others by devoting considerable time and attention to portraying trends in mass opinion. This study explores the rationale for theories of impersonal influence, synthesizing existing research findings falling under this general theoretical framework, and investigating its psychological underpinnings using experiments embedded in representative surveys.  相似文献
