我国证人保护制度的反思与重构

证人保护制度是保障证人出庭作证的关键性措施之一.现行立法确立的证人保护制度过于简略,缺乏可操作性,且侧重于对证人的事后保护.这种立法上的不尽如人意使证人不敢出庭作证,导致证人作证制度虚无化,因此亟待重构我国的证人保护制度.     

A research context for welfare reform

Responsibility for the social safety net continues to “devolve” from the federal to state governments, and many states are now confronting the dilemmas inherent in redesigning welfare—dilemmas that faced Congress, too, as it sought to impose new conditions on receipt of public assistance. This article argues that reforming AFDC is difficult because the public has conflicting goals: putting welfare recipients to work; protecting their children from severe poverty; and controlling costs. For 25 years, reformers have viewed requiring welfare recipients to participate in work-promoting programs as uniquely able to balance these goals. Numerous studies have shown that this approach modestly increased employment and reduced welfare costs. More substantial gains have been achieved by some “mixed-strategy” programs, which stress immediate job entry for some recipients and employment-directed education or training for others. Many people remain on the rolls, however, prompting some policymakers to argue for substituting work-for-benefits or community service work (“workfare”) for welfare after a certain period of time, and others for ending all support. The limited knowledge about work-for-benefits programs suggests that, in contrast to work-promoting activities, this approach ultimately costs money. The research record confirms that there are no easy answers in welfare reform, and that states will have to weigh the trade-offs in considering alternative strategies.     

Detracking America's schools: Equity at zero cost?

Schools across the country are ending the practice of grouping students based on ability, in part, because of research indicating that tracking hurts low-ability students without helping students of other ability levels. Using a nationally representative survey conducted by the National Center for Education Statistics, (NCES) we reexamine the impact of tracking on high school student achievement through the estimation of a standard education production function. This approach allows us to control for the possibility that track is correlated with factors such as class size and teacher education. In addition, we address the possibility that there are unobserved student or school characteristics that affect both achievement and track placement. Our results indicate that abolishing tracking in America's schools would have a large positive impact on achievement for students currently in the lower tracks, but that this increase in achievement would come at the expense of students in upper-track classes.

Knowledge hubs along the Straits of Malacca

World history has known areas of relative isolation and areas of high intensity of cultural interaction. The Mediterranean Sea, the Silk Road or the Straits of Malacca can be cited as such crucial contact zones. Within these areas, centres sprung up that served as interfaces between cultures and societies. These “hubs” as we would like to call them, emerged at various points throughout the contact zones, rose to prominence and submerged into oblivion due to a variety of natural calamities or political fortunes. This paper assesses the rise and fall of trade and knowledge hubs along the Straits of Malacca from before colonialisation until today. Historical hubs of maritime trade and religiosity today increasingly establish themselves as educational and knowledge hubs. This leads us to speak of the Straits of Malacca as a chain of—not pearls—but knowledge hubs with Singapore as the knowledge hub in the region shining the brightest of all, as the data suggest. We aim to conceptually grasp this development by suggesting a model or at least a hypothesis about the rise and movement of knowledge hubs in general.

EU-China relations: balancing political challenges with economic opportunities

During 2005, the European Union and China marked 30 years of diplomatic relations with much fanfare. Celebrations surrounding the anniversary however belied the fact that throughout most of this period the European Union and China remained largely aloof from one another. The strengthening of EU foreign policy over time, as well as the economic reforms and new outward orientation exhibited by China have changed the dynamics of the relationship. Both sides are increasingly recognizing the potential mutual benefits that can be accrued from a closer relationship. This paper assesses EU-China relations from both economic and political perspectives. In terms of economics, it is clear that the EU must build stronger relations with China if it is to accrue the benefits of access to an expanding market with over one billion people. To do so successfully however, the EU will have to reconcile the economic and political components of its foreign policy. The EU continues to challenge the Chinese government to reform its practices on a number of issues including human rights, democratic reform, and Tibet, all of which remain bones of contention. How the EU achieves the balance between political constraints and economic opportunities is the primary focus of this paper.

International institutions and market expectations: Stock price responses to the WTO ruling on the 2002 U.S. steel tariffs

Many scholars assert that international institutions have little power to enforce laws, punish offenders, or force compliance. Others stress that international institutions are important actors, specifically in the regulation of international trade. In this paper, I show that the recent trade dispute over U.S. steel protection provides us with a critical case to evaluate the role of the World Trade Organization in settling trade disputes and specifically stabilizing expectations of market actors over future steel policy. I argue that stock prices can serve as an important tool in answering these questions. In an empirical analysis using daily steel stock prices, I find that during the 2002 WTO steel case, the WTO dispute mechanism helped market actors stabilize expectations of future trade policy.

Forensic toxicological study on adipocere formation in submerged cadavers of female albino rats intoxicated with cadmium

There is a dearth of information on the mutual interaction between metal intoxication and adipocere formation. Herein, 40 adult female albino rats were distributed into two equal groups, one used as control while the other orally administered single dose of cadmium chloride (CdCl₂) 225 mg/kg·bw (LD_min). Control group was killed by cervical dislocation. Half of dead rats of both groups were subjected for determination of iodine value and estimation of cadmium (Cd) residues while the other half of both groups were submerged in opened glass container previously filled with 4 L dechlorinated tap water kept in closed room with an open air access (one cadaver/container). Gross morphological changes of submerged cadavers were recorded weekly along the experiment. At the end of the experiment, after 3 months, samples were collected again for iodine value determination and estimation of Cd residues. The obtained results revealed the depressant effect of Cd toxicity on development of adipocere. Cd residues were found in different tissues of cadavers at time of death with the highest amount in the intestines followed by the liver and kidneys, then lungs, adipose tissue, muscles, and finally the bones. After 3 months of water submersion, tissues exhibited significant decrease in the amount of Cd residues but to a limit that was still detected. This study concluded the possibility of detection of Cd residues even after adipocere formation. Additionally, it shed light on the possibility of the interference of environmental pollution with the natural rate of decomposition especially adipocere formation.
