Do internal symmetries get restored in hot and dense SUSY?

I offer some computational details and useful and concise formulae to calculate the effective potential for a general abelian supersymmetric model at high temperature and density. It will be shown that such cases are very good candidates for symmetry nonrestoration at high temperature, providing large densities are present.Comment: 3 pages, uses sprocl.sty, talk given at the International Workshop COSMO97 on Particle Physics and the Early Universe, 15-19 September 1997, Ambleside, Lake District, England, to be published in the Proceeding

High Temperature Symmetry Nonrestoration

This is a short review on the subject of symmetry nonrestoration at high temperature. Special emphasis is put on experimental discoveries and different theoretical mechanisms. At the end, possible cosmological applications are briefly mentioned.Comment: 7 pages; plenary talk at COSMO99, Trieste, Italy, Sep 27 - Oct 2, 1999; to appear in the proceedings; minor text changes and new references adde

Privatization of health sector in ex socialist states

Privatization of health care system in ex socialist states is one of the most controversial political and legal questions. On one part there is a widening discrepancy between the costs of health care system and the capability of public finances to cover these costs. On the other part there is a widening discrepancy between the users’ expectations and the technical and personal capability of health care system. So many governments in ex socialist countries see the privatization of health care system as a magical stick which will resolve all the problems. With privatization governments want to achieve following goals: - to improve the cost – benefit relation in health system; - to enlarge the citizens’ responsibility to live healthy; - to prevail the responsibility for the development of health system to private sector; - to liberate themselves from the political responsibility for malfunctioning health care system. Modern local governments are increasingly outsourcing to private firms for public service provision. Privatization is used as a solution where government programs are failing because private firms offer flexibility in program operation and management and are more adept at responding to changing circumstances than governmental entities. Governments also benefit from private partnerships by way of the resulting resources and personnel that become available for other uses. In this submission I’ll try to discuss about the problems of health care system’s privatization in ex socialist countries and about the necessary regulatory steps to be used for successful and citizens’ friendly privatization.privatizaton of health sector; regulatory action

Legislative powers and (X)NGO’s

(X)NGOs1 in nowadays world become more and more important player who not only fulfill the humanitarian goals but also fulfill political goals of it members or even its sponsors. For (X)NGOs late task becomes easier because state uses them as auxiliary legislator. There are diverse reasons for such practice such as: - modern states wants to promote their economy by omitting expensive and unclear legislation (following OECD proposals for legislative reforms); - governing political parties want to pass the political responsibility for tricky political decisions to another body (i.e. collective doubt); - (X)NGOs have more accurate information on certain legislative questions than parliament or government. This article deals with two major problems. In first part it analyzes pro et contra’s for delegation of legislative powers to NGOs and possible risks of such processes. Second part takes in consideration different kind of legislative solutions how to use (X)NGOs in legislative procedure.delegation of legislative powers; deregulation; self regulation; regulatory ferorm

Public sector privatization - legal framework

With the accession of ex socialistic countries in EU the problem of public sector privatization become the most popular and at the same times the most important political question. Privatization becomes at the end of the 20th century the magical word, which will resolve all the problems and incapability in public sector. We’re talking about the sector which functioned in monopole framework with all the good and the bad sides of such system. It was the sector which was used and sometimes abused by the state to promote social, political and employment goals. On the other side, distribution, quality and quantity of public goods and services was defined by the state. So the consumers had no choice – their only choice was to use or not use such product. In some countries (like in ex SFRY) also the infrastructure for public services or goods was built with private money (direct or indirect investments) and become the social or state ownership with no remuneration. Within public sector we could speak also about the problem of authority privatization, but it’s a topic, which requires separate analyzes. The intention of this contribution is to show the problems of privatization on the supplier and on the demand side.public sector privatization; consumer protection; authority privatization

Face recognition in different subspaces - A comparative study

Face recognition is one of the most successful applications of image analysis and understanding and has gained much attention in recent years. Among many approaches to the problem of face recognition, appearance-based subspace analysis still gives the most promising results. In this paper we study the three most popular appearance-based face recognition projection methods (PCA, LDA and ICA). All methods are tested in equal working conditions regarding preprocessing and algorithm implementation on the FERET data set with its standard tests. We also compare the ICA method with its whitening preprocess and find out that there is no significant difference between them. When we compare different projection with different metrics we found out that the LDA+COS combination is the most promising for all tasks. The L1 metric gives the best results in combination with PCA and ICA1, and COS is superior to any other metric when used with LDA and ICA2. Our results are compared to other studies and some discrepancies are pointed ou
