    Public service employment : a review of programs in selected OECD countries and transition economies

    This paper examines one type of program that is used by many OECD and CEEC countries (Central and Eastern European countries) to ease the pain of structural adjustment and create jobs, namely Public Service Employment (PSE). Such programs are characterized by the employment of unemployed persons, financed by the government, to provide services and/or support infrastructure development (public works). Many of those in the"non-interventionist"camp view these programs as a waste of public funds that could be used in more productive economic investments. Some of those in the"interventionist camp"also view the programs in a similar manner and feel that, while someintervention is needed, PSE programs are not an appropriate tool. However, a number of OECD and CEEC countries are implementing such programs. This report reviews and summarizes the experiences of several countries-Denmark, France, Germany, Spain, the United Kingdom, the United States, Poland, and Hungary. While not a representative sample, some of these countries heavily emphasized the use of such programs. The American program, discontinued over 15 years ago, remains relevant because this is where some of the best research has been conducted. Hungary and Poland are included because of their obvious relevance to the situation of countries in transition.Environmental Economics&Policies,ICT Policy and Strategies,Poverty Impact Evaluation,Banks&Banking Reform,Labor Standards

    Cluster tails for critical power-law inhomogeneous random graphs

    Recently, the scaling limit of cluster sizes for critical inhomogeneous random graphs of rank-1 type having finite variance but infinite third moment degrees was obtained (see previous work by Bhamidi, van der Hofstad and van Leeuwaarden). It was proved that when the degrees obey a power law with exponent in the interval (3,4), the sequence of clusters ordered in decreasing size and scaled appropriately converges as n goes to infinity to a sequence of decreasing non-degenerate random variables. Here, we study the tails of the limit of the rescaled largest cluster, i.e., the probability that the scaling limit of the largest cluster takes a large value u, as a function of u. This extends a related result of Pittel for the Erd\H{o}s-R\'enyi random graph to the setting of rank-1 inhomogeneous random graphs with infinite third moment degrees. We make use of delicate large deviations and weak convergence arguments.Comment: corrected and updated first referenc

    Femtosecond Self-Reconfiguration of Laser-Induced Plasma Patterns in Dielectrics

    Get PDF
    Laser-induced modification of transparent solids by intense femtosecond laser pulses allows fast integration of nanophotonic and nanofluidic devices with controlled optical properties. So far, the local and dynamic nature of the interactions between plasma and light needed to correctly explain nanograting fabrication on dielectric surfaces has been missing in the theoretical models. With our numerical approach, we show that a self-consistent dynamic treatment of the plasma formation and its interaction with light triggers an ultrafast reconfiguration of the periodic plasma patterns on a field-cycle time scale. Within this framework, a simple stability analysis of the local interactions explains how the laser-induced plasma patterns change their orientation with respect to the incident light polarization, when a certain energy density threshold is reached. Moreover, the reconfigured sub-wavelength plasma structures grow into the bulk of the sample and agree with the experimental findings of self-organized volume nanogratings. Mode coupling of the incident and transversally scattered light with the periodic plasma structures is sufficient to initiate the growth and the self-organization of the characteristic pattern with a periodicity of a half-wavelength in the medium.Comment: 8 pages, 7 figure

    Hepatitis C: A Perspective Through the Social Ecological Model

    Get PDF
    Hepatitis C virus (HCV) is a major global public health problem. The Center for Disease Control and Prevention (CDC) estimates that the Hepatitis C virus (HCV) affects 3.2 million Americans and 500 million people from a global standpoint (CDC, 2012). HCV contributes to significant morbidity and mortality with about 1 million deaths due to liver disease (World Hepatitis Alliance, 2010). Chronic liver disease has origins ranging from acquired, infectious, toxic and metabolic causes. Long-term consequences include cancer, cirrhosis (scarring of the liver), and liver failure. Given the substantial data attributable to HCV-related liver disease, it is necessary to develop an HCV-related public health plan for the prevention of new HCV infections. The source of HCV infection includes transfusion of blood or blood products from unscreened donors, exposure to blood through the use of contaminated and inadequately sterilized instruments and needles used in medical and traditional medicine, persons who participate in high-risk sexual practices, or sexual interactions with HCV-infected persons. The relative contribution of these various sources of infection has not yet been defined with population-based epidemiological studies. Many do not seek care because they don\u27t know they are infected; the incubation period for HCV can be decades long (Kamal, 2008). It is difficult to prevent and control chronic liver disease due to the contributing factors. There is also lack of knowledge and awareness about HCV treatment, which is a major barrier to those already diagnosed. Future challenges to public health practice will be significant as more adults are diagnosed with HCV

    Regulating Physician Behavior: Taking Doctors’ \u27Bad Law\u27 Claims Seriously

    Get PDF
    Physician behavior is a key target of government regulation intended to improve the efficiency, quality, and accessibility of health care. Yet according to physicians’ bad law claims, the legal effort to promote patient health and well-being has actually caused significant harm. These bad law claims - that malpractice litigation prompts defensive medicine, that patients’ rights policies prompt doctors to provide futile care, that controlled substance laws cause physicians to undertreat patients in pain - have diminished in significance due to the deconstruction of professionalism. Claims are often discarded as the cries of bad apple doctors or in the interest of creating a more egalitarian or consumer-oriented model of medicine. This article argues that physicians’ bad law claims should be taken seriously. The way physicians react to legal requirements can negatively impact the effectiveness of the law and the quality of patient care. Thus physician behavior must be included as an important factor in the effort to evaluate and improve the performance of the law. Taking seriously physicians’ bad law claims is a first step to understanding how physicians react to legal risks and consequently, how well laws perform. This article begins by addressing the dynamic relationship between the health law reform agenda and the medical profession. Part II considers categories of physicians’ bad law claims, recognizing that some may be dishonest or misinformed but arguing that many claims have credence as legitimate responses to extralegal shadow systems or truly harmful legal standards. Part III assesses common responses to physicians’ bad law claims. Providing specific examples, the article argues that current responses - e.g. educating doctors on the law; immunity statutes; safe harbor provisions - are inadequate because they fail to account for the realities of the medical professional or the nature of the law Finally, Part IV makes two recommendations for taking physicians bad law claims seriously and thereby effectively evaluating and improving the reform effort. First, it advocates evaluating the law through its population-based effects on physician behavior. Second, it recommends tailored monitoring and investigative processes that allow formal legal standards rather than policy decisions to govern the regulatory process
