The existing literature on economic sanctions has rarely addressed the key question of comparing the effectiveness of positive and negative sanctions. It is the contention of this study that positive sanctions can potentially be more effective, even in cases where contentious "high politics" issues are being negotiated, relations between the states concerned are tense and militarized, and the state being targeted with sanctions has substantial military power. This assertion will be tested in a set of case studies drawn from German-Polish and German-Russian/Soviet relations from the nineteenth century to the present. It will be shown that positive sanctions can be used effectively, both as "specific" sanctions to influence a target state on one particular issue, and as "general" sanctions, which aim to change the state's behavior as a whole in a more slow and subtle process.  相似文献

Abstract: The Health Protection Branch (hpb ) of Health Canada has recently undergone considerable policy and organizational renewal, with numerous and broad‐ranging implications for the evaluation of drug product safety and efficacy. From a public‐health perspective, however, the criteria used to develop organizational and policy change at the hpb have provided a sub‐optimal basis for reform, due primarily to the many forms of market failure to which the regulation of pharmaceuticals is subject. For example, thepartnership andefficiency criteria that guided policy renewal have led to the transfer of important responsibilities to partners, with the potential for either a conflict of interest or inadequate information, for which the legal basis is not always clear. The resulting realignment of the hpb's roles and responsibilities may be characterized as leading to a shift from a comprehensive approach to public‐health protection to one based on strategic risk management, with responsibilities dispersed among government, industry, academia and consumers. The rebalancing of goals in the redesign of the regulatory process suggests a change in the role of the state in the context of public‐health protection and highlights issues of concern to the public interest that may not be fully recognized as deregulation occurs in other sectors of the economy. Sommaire: La Direction générale de la protection de la santé (dgps ) de Santé Canada vient de subir un vaste remaniement de politiques et d'organisation qui entraîne de nombreuses et profondes répercussions sur l'évaluation de la sûreté et de l'efficacité des produits pharmaceutiques. Cependant, du point de vue de la santé publique, les critères auxquels on a fait appel pour modifier les politiques et l'organisation de la dgps n'ont permis qu'une base de réforme sous‐optimale, à cause surtout des nom‐breux genres de défaillance du marché qui affligent la réglementation des produits pharmaceutiques. Par exemple, les critières depurtenariat etd'efficacité qui ont guidé le remaniement des politiques ont amené le transfert d'importantes responsabilites à des partenaires moyennant le risque de. conflit d'intérêts ou d'informations inadéqaates, sans pour autant assurer une base juridique Claire. On pourrait donc dire que cette réorientation des rôles et responsabilités de la dgps fait que l'on passe d'une approche globale en matière de protection de la santéà une gestion stratégique du risque, la responsabilité en étant dispersée parmi le gouvernement, l'industrie, les milieux universitaires et les consommateurs. Le rééquilibrage des objectifs dans le remaniement du processus de réglementation suggère une évolution du rôle de l'État en ce qui concerne la protection de la santé publique; il met aussi en relief des questions d'intérêt public qui n'ont peut‐être pas été reconnues alors que la déréglementation prend lieu dans d'autres secteurs économiques.  相似文献

The paper notes that while much work has been done in the past on corruption in government and business, relatively little attention has been devoted to corruption in academic institutions. The principal forms of academic corruption are plagiarism and various forms of cheating, research fraud and financial fraud. Two simple mathematical models are proposed for exploring the motivations for (1) plagiarism, which is essentially a solitary crime, and (2) bribery. The responsiveness of the demand for the first of these, and the demand for and supply of the second to changes in underlying parameters are explored.  相似文献

The right to die may be among the most legally complex and culturally sensitive areas of civil rights to emerge in our time. The thorny issues associated with a terminally ill individual's right to self-determination, and the disposition of individuals who are incompetent to make right to die decisions for themselves, promises to keep all parties involved - health care professionals, medical ethicists, families, lawyers, judges, and state legislators -busy for some time to come. To this point, the state courts have taken the lead in the right to die debate, while the state legislatures have tended to drag their collective feet. This article lays the case law groundwork for right to die decision making, then goes on to assay the legislative responses to the issue that have been rendered in the fifty states.  相似文献

While the holdings in Davidowitz and Arkansas Blue Cross & Blue Shield arose in different contexts, they both reflect the courts' increasing willingness to consider the importance of cost containment in the health insurance arena, even though patient accessibility to health care may be restricted as a result. If the holding in Davidowitz is not successfully appealed, providers may need legislative relief in order to retain their ability to take valid assignments of patient claims for payment from ERISA plans. It is uncertain whether such legislation can be sought at the state level or must instead come from Congress due to ERISA preemption of state legislation. Clearly, the district court decision on remand in Arkansas Blue Cross & Blue Shield will be closely watched for any light it may shed on this question. On a pragmatic note, providers who have not entered into "participation" agreements with insurers or other private payors may now have a greater incentive to do so, and "nonparticipating" providers who continue to obtain assignments from patients in order to collect directly from insurers or other private payors should determine on a case-by-case basis whether the source of the patient's benefits is a group health plan--which is likely to fall under ERISA and may contain nonassignment provisions--or some other form of coverage. For an additional perspective on insurers' responses to copayment waivers, see Newsletter, Vol. 6, No. 10, October 1991, at 7.  相似文献

"Whatever, in connection with my professional practice, or not in connection with it, I see or hear, in the life of men, which ought not to be spoken of abroad, I will not divulge, as reckoning that all such should be kept secret."(1) "Safeguards to privacy in individual health care information are imperative to preserve the health care delivery relationship and the integrity of the patient record."(2) As early as the fourth and fifth centuries B.C., Hippocrates contemplated the importance of medical information to the care and treatment of patients. His oath suggests that privacy of a patient's medical information creates the foundation upon which a patient reposes trust in his or her physician. While defining the earliest version of the physician-patient privilege, the oath does not envision the extent of modern day access to healthcare information. A patient's relationship with the modern healthcare delivery system often includes a team of physicians, nurses, and other clinical support personnel. This relationship extends beyond direct caregivers and may include healthcare administrators, payor organizations, and persons unfamiliar with a patient's identity, such as researchers and public health officials. Accessing a patient's medical information links these participants to the patient's healthcare delivery relationship. The Hippocratic Oath does not contemplate such broad access, nor does it contemplate the emerging privacy crisis resulting from the application of computer technology to medical record storage and retrieval. The combination of broad access, individual privacy rights, and computer technology requires a rethinking of measures designed to protect the realities of the modern medical information society.  相似文献
