A comment on Coale's life table construction

In a recent issue of Population Index, Coale (1984) described a method of deriving a life table for an intercensal period separated by T years from 2 census single-year age distributions of a closed population. This note examines the formula used by Coale and points out that although it works well for all practical purposes, the formula with his new growth rate is an approximation, not an identity as is assumed by Coale. The Coale formula involves more steps than the usual method of estmating mortality and yields less accurate results. Coale's formula is explained. In general, in the case under consideration, if a larger cohort is followed by a smaller cohort, the survival probability calculated by the formula exceeds unity, whereas if a smaller cohort is followed by a larger cohort, the calculated survival probability becomes less than unity. The size of the relative cohorts determines the degree of error in the calculated probability. The formula does not give the survival probability of unity as it should if it were an identity. The formula in the continuous time is an identity. Feeney's alternative method presented in Coale's Computational Appendix 3 produces an exact life table without using any formula. Feeney's method is, however, less accurate than the usual method, given the same data, because it omits some information. The Coale procedure losses its usefulness in that it requires extra data manipulation, only to yield less accurate results.     

The environmental problems in urban communities and the protection of the environment in Korea

Korea's urban environmental problems, specifically air and water pollution, government environmental policies, and the role of nongovernmental organizations (NGOs) in protecting the environment are described and discussed. Korea's rapid industrialization and urbanization between 1961 and 1985 led to an increased volume of waste and air pollution. Automobiles increased in number from 29,234 in 1961 to 1,113,430 in 1985. In the same period, the number of factories with at least five employees rose from 15,204 to 44,037. The volume of chemical materials and agricultural chemicals dramatically increased. Household wastes in urban areas increased from 26,831 tons per day in 1978 to 61,072 tons per day in 1985. Industrial waste rose from 13,130 to 33,349 tons per day in 1985. Respiratory diseases are precipitated by exposure to sulphur dioxide, which is produced during cooking and heating with coal briquets; to nitrogen dioxide from automobile exhaust; and to carbon monoxide from coal briquets. Indoor air pollution from particles such as radon, asbestos, cigarette smoke, fungus, and bacteria also impacts on health. Tolerance limits have been reached or surpassed in many cities, particularly in Seoul. Air pollution is worse during the winter. The poor are particularly affected because of the continued use of coal briquets for heating. Industry contributes to water pollution. The volume of industrial waste water quadrupled between 1980 and 1990. In Seoul, however, population size directly contributes to 64.3% of water pollution, and the remaining 35.2% is from factories. Although livestock contributes to only 0.5% of water pollution, livestock drainage contributes to 36.3% of chemical materials in polluted water. Biological oxygen demand has also exceeded tolerance limits. Water reservoirs contain toxic chemicals such as lead, copper, mercury, arsenic, phenol, phosphorus, and nitrogen, which take a longer time to affect health. The Anti-Pollution Law of 1963 and the Environmental Protection Law of 1977 were adopted, but public participation was problematic, and funding for assessment was limited. NGOs have been active in environmental programs since democratization in 1987.     

Non‐Manipulable House Allocation With Rent Control

In many real‐life house allocation problems, rents are bounded from above by price ceilings imposed by a government or a local administration. This is known as rent control. Because some price equilibria may be disqualified given such restrictions, this paper proposes an alternative equilibrium concept, called rationing price equilibrium, tailored to capture the specific features of housing markets with rent control. An allocation rule that always selects a rationing price equilibrium is defined, and it is demonstrated to be constrained efficient and (group) non‐manipulable for “almost all” preference profiles. In its bounding cases, the rule reduces to a number of well‐known mechanisms from the matching literature. In this sense, the housing market with rent control investigated in this paper integrates several of the predominant matching models into a more general framework.     

Experimental Games on Networks: Underpinnings of Behavior and Equilibrium Selection

In this paper, we describe a series of laboratory experiments that implement specific examples of a general network structure. Specifically, actions are either strategic substitutes or strategic complements, and participants have either complete or incomplete information about the structure of a random network. Since economic environments typically have a considerable degree of complementarity or substitutability, this framework applies to a wide variety of settings. We examine behavior and equilibrium selection. The degree of equilibrium play is striking, in particular with incomplete information. Behavior closely resembles the theoretical equilibrium whenever this is unique; when there are multiple equilibria, general features of networks, such as connectivity, clustering, and the degree of the players, help to predict informed behavior in the lab. People appear to be strongly attracted to maximizing aggregate payoffs (social efficiency), but there are forces that moderate this attraction: (1) people seem content with (in the aggregate) capturing only the lion's share of the efficient profits in exchange for reduced exposure to loss, and (2) uncertainty about the network structure makes it considerably more difficult to coordinate on a demanding, but efficient, equilibrium that is typically implemented with complete information.     

Beyond I-You-Me: An Empirically Supported Formulation of the Triadic Self

This applied semiotics intends to show that the richness and complexity of Charles S. Peirce need not be lost through an empirical application to psycholinguistics, but instead enables the latter to make better informed hypothesis testing. It is proposed that Peircean semiotics can be used to ground a taxonomy of linguistic representations of the self in English, which is parsed not on the basis of semantics, but rather according to the triadic structure of the self as formulated by Peirce. This taxonomy was implemented by a language analysis computer program, SSWC (Sundararajan-Schubert Word Count), and applied to an analysis of language use in emotionally expressive writings. Results of two studies are reported to demonstrate the heuristic value of this applied approach to semiotics.     

BRINGING PERSONALIZED TIES BACK IN: Their Added Value for Biotech Entrepreneurs and Venture Capitalists Interorganizational Networks

Using a unique data set collected in France among biotech entrepreneurs and their venture capital investors (VCs), we measure the added value of personal relationships at the interorganizational level. Our analyses show that when two entrepreneurs share a personal collaboration tie or a personal friendship tie with a VC investor, the probability of having an advice tie and thus exchange tacit knowledge increases significantly. We confirm the importance of this kind of social embeddedness in the biotech industry where personalized ties––as opposed to institutional and contractual relationships––at the interorganizational level had not yet been examined systematically. Our results suggest that strategies of personalization of exchanges are vital for interorganizational learning. These strategies help entrepreneurs to access resources, participate in knowledge building, and co‐orientate activities in this sector.     

Safety Nets and Scaffolds: Parental Support in the Transition to Adulthood

Using longitudinal data from the Youth Development Study (analytic sample N = 712), we investigate how age, adult role acquisition and attainments, family resources, parent-child relationship quality, school attendance, and life events influence support received from parents in young adulthood. Parental assistance was found to be less forthcoming for those who had made greater progress on the road to adulthood, signified by socioeconomic attainment and union formation. The quality of mother-child and father-child relationships affected parental support in different ways, positively for mothers, negatively for fathers. School enrollment, negative life events, and employment problems were associated with a greater likelihood of receiving support. The findings suggest that parents act as "scaffolding" and "safety nets" to aid their children's successful transition to adulthood.
