Town planning in Sweden: National officials versus local politicians

With strong central government traditions, Sweden has developed goal-oriented normative planning. At urban level, such planning raises many problems. This article discusses some of these problems from the three principal aspects of planning, namely the ideological, methodological and organizational aspect. The study is based on an extensive questionnaire and oral interviews among municipal planners in leadership positions in three middle-sized municipalities, namely Borås, Umeå and Västerås. The ideological aspect is discussed with reference to restrictions on urban planning arising as a result of decisions made by private enterprises and due to the interaction between the central and municipal government. The article goes on to describe the methods planners have developed to plan for land-use, resource allocation, housing and other sectoral activities and major defects in the planning system. Finally, the article discusses various problems faced by the municipal government whose departmental organization facilitates the administration of community services but cannot adequately deal with the increasing number of planning functions which are often interdepartmental in nature.     

Credit programs for the poor and reproductive behavior in low-income countries: Are the reported causal relationships the result of heterogeneity bias?

Group-based lending programs for the poor have drawn much attention recently. As many of these programs target women, an important research question is whether program participation significantly changes reproductive behavior and whether the gender of the participant matters. Using survey data from 87 Bangladeshi villages, we estimate the impact of female and male participation in group-based credit programs on reproductive behavior while attending to issues of self-selection and endogeneity. Wefind no evidence that women s participation in group-based credit programs increases contraceptive use or reduces fertility. Men So participation reduces fertility and may slightly increase contraceptive use.     

A Predictive Model for Financial Literacy among the Educated Youth in Kerala,India

ABSTRACT

The economic importance of financial literacy among individuals necessitates policy intervention. Estimation of financial literacy is a prerequisite for strategies to improve financial literacy. This paper, using data collected from the educated young adults in Kerala, the most literate state in India, builds a predictive model for financial literacy employing logistic regression. The study reveals the low level of financial literacy in the state. The model points to the significance of gender, age, religion, discipline of study, occupation, and personal income as determinants of financial literacy. The findings have implications for policies aimed at improving the financial literacy of young adults in India.     

A new adaptive EWMA control chart using auxiliary information for monitoring the process mean

The adaptive memory-type control charts, including the adaptive exponentially weighted moving average (EWMA) and cumulative sum (CUSUM) charts, have gained considerable attention because of their excellent speed in providing overall good detection over a range of mean shift sizes. In this paper, we propose a new adaptive EWMA (AEWMA) chart using the auxiliary information for efficiently monitoring the infrequent changes in the process mean. The idea is to first estimate the unknown process mean shift using an auxiliary information based mean estimator, and then adaptively update the smoothing constant of the EWMA chart. Using extensive Monte Carlo simulations, the run length profiles of the AEWMA chart are computed and explored. The AEWMA chart is compared with the existing control charts, including the classical EWMA, CUSUM, synthetic EWMA and synthetic CUSUM charts, in terms of the run length characteristics. It turns out that the AEWMA chart performs uniformly better than these control charts when detecting a range of mean shift sizes. An illustrative example is also presented to demonstrate the working and implementation of the proposed and existing control charts.     

ON EXTENSIONS OF PROBABILISTIC PROFIT BUDGETS: A COMMENT

Recognizing the potential importance of new uses of analysis, the author provides an alternative approach for constructing the confidence interval (C.I.) for the population coefficient of variation, V=α/μ. More specifically, the comment demonstrates the use of some of the existing percentage points of the sample coefficient of variation, v=s/x . The results of these approximations are then compared empirically with the results recently published by Hayya, Copeland and Chan [1, pp. 115–118]. The available approximations given by Iglewicz [2] and again by Iglewicz and Myers [3] of the practical range of V and of the sample size n are more accurate than those obtained using the method in [1].     

Greenhouse gases and green roofs: carbon dioxide and methane fluxes in relation to substrate characteristics

Green roof systems have been increasingly implemented to enhance vegetation cover and associated ecosystem services in urban spaces, with primary goals being the reduction of peak surface runoff, enhanced water quality, and mitigation of urban heat island effects. Recently, green roofs have also received attention as a means to enhance carbon sequestration, but direct measurements of greenhouse gas fluxes from established green roof systems are largely lacking. Here we present observations of CO₂ and CH₄ fluxes from substrates of experimental extensive green roof units that varied in vegetation type (Sedum spp., and a native meadow species mix), substrate depth, substrate type (high vs. low organic matter content), and irrigation. We predicted that substrate CO₂ effluxes would be higher in high-organic-matter substrates and that systems with high organic matter would potentially act as CH₄ sources. Substrate fluxes were low compared to natural soils, with seasonal means ranging from an efflux of 0.1–0.4 µmol CO₂ m^-2.s^-1 and uptake of ~0.00–0.04 nmol CH₄ m^-2.s^-1, with higher fluxes late in the growing season. CO₂ fluxes showed large increases in response to irrigation and were higher from the high-organic-matter substrate and with increased substrate depth. The strength of the CH₄ sink increased in response to prior irrigation treatments, and CH₄ emissions were detected only on low-organic-matter substrates early in the growing season. No effects of vegetation type were detected for either CO₂ or CH₄ flux. Our results indicate that high levels of organic matter in green roof substrates may enhance aerobic soil respiration but are not associated with CH₄ emissions, which instead were only detected in low-organic-matter substrates.

     

Examining the relationship between religiosity and happiness in Medan,Indonesia: The mediating role of self-control,self-regulation,and life satisfaction

Social harmony and community wellbeing can be addressed by promoting life satisfaction and happiness within society. As part of the attempts to understand and promote life satisfaction and happiness within society, this study examined how religiosity can contribute to these two outcome variables. More specifically, this study examined the mediating effect of self-control, self-regulation, and life satisfaction on the relationship between religiosity and happiness. Six hundred and twenty-eight middle (628) adults from Medan, Indonesia were recruited through stratified sampling. They completed five self-report scales on Subjective Happiness Scale; Satisfaction with Life Scale; Centrality of Religiosity Scale; brief Self-control Scale and Self-regulation Scale. Data were analyzed by applying Structural Equation Model (using the LISREL software 8.80), which provides simultaneous examination of variance between endogenous and exogenous variables. Results revealed that people who reported higher level of religiosity also scored high on self-control and self-regulation scales, life satisfaction, which, in turn, are related to more happiness. The finding provides evidence for more specific mechanism in which religiosity contributes to life satisfaction and happiness of the individuals and consequently society wellbeing. Theoretical and practical implications related to the findings are discussed.
