Falling Short of Highest Life Expectancy: How Many Americans Might Have Been Alive in the Twentieth Century?

Life expectancy at birth in the United States during the twentieth century was lower than in many other highly developed countries. We investigate how this mortality disadvantage in the last 100 years translates into the number of hypothetical lives lost and their sex and age structure. We estimate the hypothetical US population if it had experienced in each decade since 1900 the mortality level of the country with the then highest life expectancy and compare the results to the actual figures in 2000. By 2000, the number of additional people who could have been alive had the mortality levels in the United States been as low as those in countries with the highest life expectancy was 66 million. This number is distributed equally between males and females. Suboptimal mortality at reproductive ages is crucial for the cumulative effect of potential lives lost, resulting from premature deaths of women who could still become first‐time mothers or bear additional children. Out of the 66 million additional persons who could have been alive in 2000, 45 million are attributable to those indirect deaths. Although the differences in the composition of the population by sex and age under the two mortality regimes are minor, the majority of people who might have been alive—54 million—were of working age or younger.     

Changing the development policy paradigm: Investing in Social security floor for all

The Paper briefly reviews social security coverage that the world has achieved and summarizes economic and social benefits of a national social security system. It then goes on to argue that social security systems are a necessary part of the institutional framework of any effective market economy, creating—among other things—societal cohesion that is needed for long-term economic development. It makes the case that the introduction of basic social protection in developing countries is both a desirable and an affordable investment in their social and economic development. It estimates the global minimum investment cost to provide basic social security and finally suggests international instruments to introduce a global social security floor.

Innovativeness of social economy entities in Poland. An empirical study from the perspective of Positive Organizational Scholarship

The Polish system of tackling social exclusion is based on social economy entities, such as social integration centers and social cooperatives. The aim of the article is to define the essence and conditions of their innovativeness while answering the question to what extent the organizations can make use of management theories created for business entities. The empirical basis for the article are 3 focus group interviews with representatives of social integration centers and social cooperatives operating in Poland. The results suggest that low innovativeness of the entities is, among others, the effect of an authoritarian management style and a lack of care about positive relationships among employees.     

Moments-Based Approximation to the Renewal Function

Asymptotic behavior of the number of independent identically distributed observations in a left or right neighborhood of k _n th order statistic from the sample of size n, for k _n /n → α ? [0, 1], is studied. It appears that the limiting laws are of the Poisson type.     

Is There Any ‘Law of Requisite Variety’ in Construction of Indices for Complex Systems?

The issue of design of indicators for complex socio-economic systems, described by multiple characteristics (variables) is considered in this paper primarily from the point of view of the purpose, for which the indicators are developed and used, and the available instruments, which can be used to achieve this purpose. Hence, the paramount importance is assigned to the correspondence between the space of observed variables and the space of possible actions or instruments, as potentially leading to the design of the “optimum indicators”. The close association between the design of indicators and the available (or also designed) policy instruments is justified in the framework of the classical decision making feedback loop. The proposal is illustrated with the case of a group of models from the modelling project that was carried out at the Systems Research Institute, Polish Academy of Sciences, in close collaboration with the Institute of Geography and Spatial Organization, also of the Academy, devoted to the development and implementation of a system of forecasting models for a series of variables, characterising the socio-economic situation of the capital province of Masovia, and its particular administrative units.     

Optimal Nonparametric Quantile Estimators. Towards a General Theory. A Survey

“Nonparametric” in the title is used to say that observations X ₁,…,X _n come from an unknown distribution F ∈ ? with ? being the class of all continuous and strictly increasing distribution functions. The problem is to estimate the quantile of a given order q ∈ (0,1) of the distribution F. The class ? of distributions is very large; it is so large that even X _nq:n , where nq is an integer, may be very poor estimator of the qth quantile. To assess the performance of estimators no properties based on moments may be used: expected values of estimators should be replaced by their medians, their variances—by some characteristics of concentration of distributions around the median. If an estimator is median-biased for one of distributions, the bias of the estimator may be infinitely large for other distributions. In the note optimal estimators with respect to various criteria of optimality are presented. The pivotal function F(T) of the estimator T is introduced which enables us to apply the classical statistical approach.     

Sing … Then Think: Musical Interventions and Nondeliberative Forms of Practice in Social Work Groups

ABSTRACT

The positive effects of music have been demonstrated worldwide in many fields including social work, psychology, medicine, and education. Musical interventions including music listening, lyric analysis, and singing have also been found effective in group work. This article, guided by Norma Lang’s nondeliberative theory, aims to provide the “why,” “when,” and “how” of incorporating music into social work groups. It also provides the reader with a toolbox of musical interventions and the encouragement to utilize these “artful, actional, and analogic” activities in group work.
