A note on social choice theory without the Pareto principle

This paper was originally submitted to Journal of Economic Theory and was accepted. After presenting it at the first meeting of the society for social choice and welfare in Caen, France, we were informed by Professor Bernard Monjardet that a weak version of our main result (Proposition 1) had been proved in Y. Murakami's book, Logic and Social Choice, Routledge and Kegan Paul, London, 1968. We later voluntarily withdrew the paper from JET even though the editor was still willing to publish it on the ground that it would do the profession a service by making more people aware of a simple yet fundamental result in social choice theory. Instead we decide to submit this paper to Social Choice and Welfare, hoping that it will reach the intended readers more effectively.     

Political extremism,group membership and personality traits: who accepts violence? / Extremismo político,pertenencia al grupo y rasgos de personalidad: ¿Quién acepta la violencia?

Abstract

Identity fusion theory proposed that fused individuals have a visceral feeling of oneness with the group and this leads them to engage in radical, violent pro-group behaviours. Other approaches to group extremism link acceptance of violence to right-wing authoritarianism (RWA) and social dominance orientation (SDO). We extended previous research on fusion in three ways. First, by exploring if identity fusion is a significant predictor of the willingness to fight for a group, when controlling for group identification, left-wing authoritarianism (LWA), RWA and SDO. Secondly, we controlled for a membership in a group known for radical action directed at out-groups, namely football hooligans. Finally, we added a second outcome variable, which is the acceptance of violent change of the current social system. The participants were self-described football hooligans (N = 24) and undergraduate students (N = 155). Regression analyses revealed that the strongest predictor of willingness to defend in-group was identity fusion, with RWA and group identification significant as well. RWA and LWA emerged as the strongest predictors of acceptance of violent change. The effect of group membership wasn’t significant.     

Social work students’ perceptions of obesity

Research indicates that mental health and medical professionals often hold negative views of overweight or obese people. Little is known about weight prejudice among social work students. In order to address this gap in the literature, this study examines the attitudes of Bachelor of social work and Master of social work students (n = 250) toward persons who are overweight and/or obese. Consistent with the literature, findings indicate generally those with higher body mass index scores are more likely to believe that obesity is beyond their control. Further, although age was correlated with Beliefs About Obese People scores, it was not a significant predictor. Implications for social work social justice and cultural competency curriculum are discussed.     

The age-testosterone relationship in black,white, and Mexican-American men,and reasons for ethnic differences

Recent studies give contradictory findings regarding testosterone levels in white, black, and Hispanic men. Here, I present a cross-sectional reanalysis of serum testosterone and sex hormone-binding globulin (SHBG) in 1637 males, aged 12–90, who participated in the morning examination of the Third National Health and Nutrition Examination Survey (NHANES III) during the year 1988–1991. Testosterone and SHBG in males are described precisely over the age range 12 to 90 years. Testosterone and SHBG are not notably different in white and Mexican-American (MA) males. In the age range 20–69 years, black men average 0.39 ng/ml higher testosterone than white and MA men (p < 0.001). The higher testosterone in black men is partly explained by low marriage rate and low adiposity.     

Informed Consent in the Twenty‐First Century: What It Is,What It Isn't,and Future Challenges in Informed Consent and Shared Decision Making

Consent evolved from judge‐made law in Great Britain in 1767. The term informed consent entered the judicial lexicon in 1957. The first court case to articulate a reasonable person standard adopted by the high courts in Canada and Australia was heard in the U.S. in 1972. Today, informed consent continues to develop in four areas: (i) the court‐based doctrines of consent and informed consent in clinical care in judge‐made law; (ii) federal regulations related to research on human study participants; (iii) shared decision making adopted by care organizations and medical societies in the US, Canada, and Europe; and (iv) areas including decision analysis, discourse analysis, ethics, linguistic analysis, patient–physician communication, risk and evidence communication, and social theory. In this paper, we will focus on consent and informed consent in the first part of the twenty‐first century. We will examine a range of information and decision making frameworks from the oldest court‐established frameworks of consent and informed consent to recent conceptions of information and decision making in evidence‐based decision making and shared decision making in the patient–physician relationship. This paper is divided into three parts: I. What informed consent is, II. What informed consent isn't, and III. Future challenges in informed consent and shared decision making.     

Constructing fertility tables for Soviet populations

Because the 1970 Soviet Union census does not provide information on the age structure of men and women separately by sex and according to their ethnic affiliation, the 1959 USSR census data serve as the basis to infer knowledge about ethnic fertility. The model takes into account (1) the total number of births in 1960, estimated from the child-woman ratio in 1959, (2) the age structure of women in 1959, and (3) the assumed pattern of age-specific birth rates structured in terms of the modal age at childbearing and the length of the fertility age span. The results show that Ukrainians among the Slav populations ranked as the lowest with 2.07 children born per woman. Their total fertility contrasts with that of Kazakhs native to Central Asia, who reportedly according to Soviet sources had 7.46 children per woman in 1958-1959, and whose estimated rate is around 8.59 children. Extreme variations appear in the estimates of fertility among nationalities of the Caucasus region, Volga Basin, and to a lesser degree in Siberia. Official Soviet calculations of crude birth rates and age-specific rates for 15 Union Republics in 1967-1968 are transcribed and compared with the estimates for nationalities in 1959-1960. The same theoretical model used to generate the Soviet rates may be adapted under different assumptions to non-Soviet populations in other situations where the data are scanty or incomplete.     

Tools of innovative public procurement in health care in Poland

This paper sets out to map the issues of innovation in public procurement in Poland with specific reference to health care and presents case studies of Polish hospitals using an innovative approach to public procurement. It is based on the analysis of secondary data collected using Internet search engines, introductory research conducted in hospitals which have recently used innovative procurement tools (e.g. technical dialogue and competitive dialogue) and the experience of two Polish hospitals involved in projects aimed at increasing the efficiency of procurement through innovations, described in a case study form. Although innovative procurement in Poland is at an early stage of development, it is also a topic of growing interest to both public authorities and hospitals and some hospitals are adopting new procurement methods such technical and competitive dialogue. However, barriers to the adoption of new procurement approaches are evident and these delay this process of adoption. Barriers encountered include the conservative organizational culture of hospitals, lack of awareness and know-how and a lack of trust and understanding of new procurement approaches.     

The influence of human fertility on the economic conditions of the rural population in poland

Summary In 1970, Polish women in agricultural households reported larger numbers of children born alive than women in other occupations. When controlling for the influence of age at marriage and duration of marriage, the average number of children born per women among the farming population increased directly with the amount of privately owned agricultural land. Consistently, women whose principal source of livelihood was derived from non-agricultural sources even though they resided in villages, showed lower fertility than those in the agricultural sector, but significantly higher fertility than city women. This study is based on the five per cent sample of ever-married women between 15 and 70 years of age interviewed about their past reproductive histories in Poland during the 1970 Census of Population.The conclusions identify the high level of human fertility in rural populations as the main determinant of economic status among Polish peasants whose sources of support derive primarily from farming. Additional evidence supporting the hypothesis of dependence of the agricultural economy on the force of human reproduction is based on data for Slovakia and the Czech regions.     

Inequality in an OLG economy with heterogeneous cohorts and pension systems

We analyze the consumption and wealth inequality in an OLG model with mandatory pension systems. Our framework features within-cohort heterogeneity of endowments and heterogeneity of preferences. We allow for population aging and gradual decline in TFP growth. We show four main results. First, increasing longevity translates to substantial increases in aggregate consumption inequality and wealth inequality. Second, a pension system reform from a defined benefit to a defined contribution works to reinforce consumption inequality and reduce wealth inequality. Third, minimum pension benefits are able to partially counteract an increase in inequality introduced by the defined contribution system, at a fiscal cost. Fourth the minimum pension benefit guarantee mostly addresses the sources of inequality which stem from differentiated endowments rather than those which stem from heterogeneous preferences.
