Proportional representation: An empirical evaluation of single-stage,non-ranked voting procedures

Rapoport, Felsenthal and Maoz (1988) have proposed three alternative methods to discern the fair proportion of seats that a party in a representative assembly ought to receive as a function of voters' preference orderings. All three methods assume that the ratio between the number of voters preferring party i over j to the number of voters preferring party j over i can be tested for consistency, and, if sufficiently consistent, can be appropriately scaled to discover the proportion of seats each party ought to receive. Using these methods as standards, we use exit-poll data gathered during the 1985 elections to the general convention of the Israeli General Federation of Labor (Histadrut) to examine the extent to which plurality- and approval-voting procedures provide a fair allocation of seats. The findings indicate that: (a) all three methods yield sufficiently consistent matrices of preference ratios; (b) the plurality- and the approval-voting procedures yielded significantly different proportional representations; (c) the proposed proportion of seats according to the three aggregation methods fall midway between the proportion of seats that the plurality and the approval procedures allocate. We discuss practical implications of these findings.

Determining the time and day of photography

Photographs taken by crime victims and perpetrators are at times important evidence. Their time of photography may also affect their value as such. Three methods of determining when a picture was taken by using the content of the picture are presented. The methods utilize solar direction-measured from shadows in the photograph, identifying flowering wild plants and correlating cloudiness with meteorological observations. Solar direction is the most accurate and involved method and therefore is the main part of this paper. A case using all three methods is described.     

Recent developments in medicine and law

This article addresses important developments in the field of medicine and the law during the last year and highlights some of the significant areas of law affecting health care providers that should be considered. Actions against health care providers may include challenges to peer review immunity, allegations concerning the practice of medicine across state lines without a license, and even accusations of wrongfully assisting a patient to commit suicide. These areas are addressed in turn by this article. Finally, antitrust developments over the last year are briefly addressed as an emerging area of concern for providers forming complex practice networks in today's health care arena.     

Improving distribution of pharmaceuticals in developing countries: A case study of The Gambia project

Without sufficient sanitation, nutrition and primary health care infrastructures, developing nations must depend on pharmaceuticals as the principal defense against debilitating diseases such as malaria, schistosomiasis, river blindness, tetanus, and leprosy. Yet the distribution of pharmaceuticals within many developing countries is severely inadequate to meet the health care needs of large sectors of the population, particularly those persons living in rural areas. The result is that with 80% of the world's population, and an even greater share of the world's serious illnesses and disease, the Third World consumes only 20% of the global supply of pharmaceuticals. One of the major obstacles confronting individuals in developing countries that need pharmaceuticals is access — the drug delivery infrastructure is often inadequate. Problems exist in the entire range of drug management: Ordering, receipt, storage, distribution, and resupply. To help combat the problems, a unique collaboration began in 1981 at the initiation of several members of the Pharmaceutical Manufacturers Association (PMA), and Africare, a private voluntary organization, to improve the drug distribution and management system in The Gambia in Africa. The purpose of this article is to demonstrate the feasibility of transferring The Gambian model of cooperation between governments in developing countries, private voluntary organizations, and the international pharmaceutical industry to other Third World nations given different cultural, political and economic parameters. Last year, after observing how effectively The Gambia project had improved record keeping and management, the government of Sierra Leone invited Africare to help set up similar improvements in its drug distribution and inventory program. Although the multinational pharmaceutical corporations are often criticized by Third World governments for overpricing and dumping drugs, and excessive marketing schemes, The Gambia project demonstrates how the industry can work with health ministries to alleviate the problem of an inadequate supply and storage of pharmaceuticals particularly to poor, rural areas in Less Developed Countries.     

On a Contradiction in Mill's Argument for Liberty

Mill took very seriously the warning example from China that even a civilised country could stagnate and become a backwater of world development. Although certain sections of Mill's On Liberty have been scrutinised, evaluated and debated with intense care, this, his most fundamental warning to his own society – that it was systematically undermining its own pre-eminence – has stimulated relatively little investigation. This article notes Mill's concern with social stagnation and suggests that, even in terms of his own presentation of the balance of social forces, his proposed countermeasures of 'eccentricity' and 'refusal to bend the knee' are futile gestures quite insufficient to combat the tendencies he outlined.     

The Law of Crime Concentration: An Application and Recommendations for Future Research

Objective

We address four outstanding empirical questions related to the “law of crime concentration” (Weisburd in Criminology 53:133–157, 2015): (1) Is the spatial concentration of crime stable over time? (2) Do the same places consistently rank among those with the highest crime counts? (3) How much crime concentration would be observed if crimes were distributed randomly over place? (4) To what degree does the spatial concentration of crime depend on places that are crime free?

Methods

The data are annual counts of violent and property crimes in St. Louis between 2000 and 2014. Temporal stability in the spatial inequality of crime is measured by computing the fraction of crimes that occur in the 5% of street segments with the highest crime frequencies each year. The spatial mobility of crime is measured by computing the number of years each street segment appears in the top 5% of street segments. Poisson simulations are used to estimate the fraction of crimes that could appear in the top 5% of street segments on the basis of chance alone. The impact of crime-free locales on the spatial concentration of crime is evaluated by comparing results from analyses that include and exclude crime-free street segments from the crime distributions.

Results

The concentration of crime is highly unequal and stable over time. The specific street segments with the highest crime frequencies, however, change over time. Nontrivial fractions of street segments may appear among the 5% with the highest crime frequencies on the basis of chance. Spatial concentration of crime is reduced when crime-free street segments are excluded from the crime distributions.

Conclusions

The law of crime concentration is not a measurement artifact. Its substantive significance, however, should be assessed in future longitudinal research that replicates the current study across diverse social settings.

     

大学如何服务于社会

大学可以以多种方式服务社会,但主要的有三种:一是基础研究。大学的基础研究促进了科学知识、技术和医学的发展,而这正是经济增长、物质生活水平提高和人类健康状况改善的基础。大学也主要是以它的这种基础研究来服务于社会的。二是人才培养。通过基础性的学术研究创造知识绝不是大学为社会做出的唯一重要的贡献,通过对学生的能力培养使其将来能够更好地为社会服务,是与学术研究同样重要的社会贡献。大学、特别是好大学的培养目标应该是培养学生的创造性、灵活性,以及解决问题、创新和领导的能力。实际上,大学正是通过这种对学生能力的培养而积极地服务于社会的。三是履行好机构性公民的义务。大学可以通过参与社区建设、提供智力支持的方式直接为当地的经济发展、邻里关系的改善等做出自己的贡献。大学也可以通过以身作则,使学生树立强烈的社会责任感来间接地为社会做出自己的贡献。
