古巴共产党与中国共产党:政治互信和互相支持的典范

承认中华人民共和国是新生的古巴革命政权自行使独立主权时起，所采取的最早的行动之一。1960年9月2日，在具有历史意义的哈瓦那革命广场，一百多万古巴人欢呼支持菲德尔·卡斯特罗同志关于古巴与中国这个兄弟国家建立外交关系的提议。同月28日，两国共同发表联合公报，宣布建立外交关系。此举使古巴成为第一个与中华人民共和国建立外交关系的拉美国家。     

On the use and misuse of profit functions for measuring the price responsiveness of peasant farmers: A comment

The standard profit function approach has been applied successfully in a number of LDCs to measure the price responsiveness of peasant farmers. Yet, various problems afflict this approach including, but not restricted to, the existence of non‐competitive market structures, zero‐valued observations, exclusion of relevant variables, lack of participation in output and/or input markets, and endogeneity of input and/or output prices. The impact of these problems on estimation results, however, can be minimised through modifications and adaptations of the standard approach, better specification of the underlying technology, and the use of selected functional forms.     

Scope of liability: the vanishing distinction between negligence and strict liability

The duty-of-care requirement cannot be used anymore as the touchstone to differentiate negligence from strict liability because it can be found in many forms of the latter. Duty of care is smuggled into strict liability hidden under the scope of liability requirement (traditionally called “proximate causation”). As far as the scope of liability requirement is common to negligence and to many forms of strict liability, there is a fairly large common ground to both liability rules, and consequently the marginal Hand formula is applied to both rules. Indeed, under a negligence rule, the marginal Hand formula is applied twice: first to assess whether or not the defendant did breach his or her duty of care, and, second, to delimit whether or not the defendant’s behavior was a proximate cause of the harm suffered by the victim. However, under a strict liability rule, the Hand formula is applied only once when the proximate causation question is raised. Traditional law and economics analysis has almost always taken the normative question raised by the causation requirement as given, which is a potential major problem due to the importance of scope of liability or proximate causation in legal practice. Defining the scope of liability, that is to say, the boundaries of the pool of potential defendants, is the basic legal policy decision for each and every liability rule. In the normative model presented in this paper, the government first chooses efficient scope of liability, and given the scope of liability, the government then decides the liability rule and damages that guarantee efficient precaution. In the article, most known scope of liability rationales developed by both common law and civil law systems are discussed in order to show the substantial common ground between negligence and strict liability.     

A comparison of adolescent inpatients with and without substance abuse using the Millon Adolescent Clinical Inventory

We compared clinical syndromes, expressed concerns, and personality styles of adolescent inpatients with substance use disorders (SUD; n=44) vs. without substance use disorders (non-SUD; n=61) using the Millon Adolescent Clinical Inventory. The two groups did not differ with regard to age, sex, ethnicity, functional severity, or the frequency of other major psychiatric disorders, and were drawn from the same overall sample population. SUD subjects showed significantly higher levels of delinquent predisposition and lower levels of anxiety. Consistent with these syndromal findings, we found that SUD subjects were characterized by higher levels of unruliness and social insensitivity and lower levels of submissiveness. Our findings suggest that, in severely disturbed adolescents who require psychiatric hospitalization, externalizing phenomena are closely associated with SUD. Our findings also suggest that internalizing problems also exist in SUD, although not at levels greater than that observed in non-SUD inpatients.Received Ph.D. in clinical psychology from the University of Pittsburgh.

What does the European Union do?

The goal of this paper is to evaluate the attribution of policy prerogatives to European Union level institutions and compare them to the implications of normative policy models and to the preferences of European citizens. For this purpose we construct a set of indicators to measure the policy-making intensity of the European Union (European Council, Parliament, Commission, Court of Justice, etc.). We confirm that the extent and the intensity of policy-making by the EU have increased sharply over the last 30 years, but at different speeds, and in different degrees, across policy domains. In recent years the areas that have expanded most are quite remote from the EEC’s original mission of establishing a free market zone with common external trade policy. On the contrary some policy domains that would normally be attributed to the highest level of government remain at national level. We argue that the resulting allocation of prerogatives between the EU and member countries is partly inconsistent with normative criteria concerning the assignment of policies at different government levels, as laid out in the theoretical literature.     

Estimation of postmortem interval using the protein marker cardiac Troponin I

The importance of determining the time since death is crucial to criminal, civil and forensic cases. A technique exploiting the degradation of a protein, cardiac Troponin I (cTnI), to estimate the postmortem interval (PMI) was investigated. Cardiac Troponin I is a basic regulatory protein found as part of a ternary complex responsible for calcium dependent muscle contraction. An efficient extraction protocol to analyze the banding pattern of cTnI in postmortem tissue was developed. The analysis involves extraction of the protein, separation by denaturing gel electrophoresis (SDS-PAGE) and visualization by Western blot using cTnI specific monoclonal antibodies. A bovine model was used to develop and optimize the protocol. The homology of cTnI amongst mammalian species allows for the cross-reaction of human anti-cTnI antibodies with bovine cTnI. The results indicate a characteristic banding pattern amongst human cadavers (n=6), a pseudo-linear relationship between percent cTnI degraded and the log of the time since death (r>0.95), and a qualitative degradation band pattern that in a simple comparative analysis with a standard human heart (known time since death) can be used to estimate the postmortem interval. The degradation-banding pattern of tissue cTnI is useful in the determination of the early postmortem (pm) interval (0-5 days). Overall, this technique offers advantages such a wide postmortem interval, measurable degradation pattern, a temporal semiquantitative relationship and manageable temperature dependence over direct temperature methods.
