Sterilization: the barriers are being crossed

The sterilization program begun in the Philippines by Presidential Decree in 1974 is described. The goals of the program are: 1) training of program practitioners, to equip a corps of physicians with needed skills; 2) recruitment of acceptors to test the acceptability and viability of the approach among eligible groups; and 3) "professionalization" of medical practice in sterilization. The training of program physicians has been taken over by Popcom as part of its 1-year sterilization training program. The institutionalization of the surgical sterilization in medical schools and family planning organizations has been undertaken by the Study and Training Center for Surgical Sterilization. Various types of sterilization clinics are described. The reaction of the population and methods of handling potential acceptors are described. Sterilization techniques and side effects are presented for male and female sterilization. 3 models for information-education-communication in sterilization are reported. The number of births averted by this sterilization program is estimated. Problems encountered are revealed.     

Women’s Political Firsts and Symbolic Representation

ABSTRACT

The extent to which politics is still a “man’s game” is made evident every time a top political office has a female holder for the first time. These incredibly revealing moments may give a new social meaning to women in politics—women’s political presence—and women and politics—gendered social constructions about women’s capacity to rule. This article explores the types of gendered mediation underpinning the representation of first-ever women serving in historically male-dominated political offices in Spain. It shows that gender media frames are pervasive, which may lead to an effective annihilation of women’s symbolic representation.     

Mechanisms for participation in the public system of social services in Spain: opportunities for the development of social work with a citizenist approach

ABSTRACT

This article presents an analysis of the opportunities for participation of citizens in the public system of social services in Spain and their impact on the design, implementation, execution and evaluation of public policies of social services at a municipal level. The study also involved performing a comparative analysis of cases, assessing the impact, in terms of contributions and possibilities of the councils, upon the increased democratization of local public policies in terms of social welfare and the improvement of the efficiency with which social services and benefits are managed. The results of these investigations permit us, first of all, to present the diverse opportunities on offer for participation at a regional level in social services in Spain and then to identify, from its participants, dimensions that intensify processes of democratization and therefore help to improve efficiency of public well-being policies at a municipal level. In the case of the autonomous communities, we must highlight the changes that new social services laws have brought about in terms of widening citizens’ participation and opening up feedback for users of the system at a local level. In addition, this article discusses the role of different typologies and explores mechanisms, bodies and processes of participation that are applied in the design, management and assessment of social services policies at a local level. Finally, we determine which factors help to increase the efficiency of social public policies, as revealed by increases in citizens’ participation in local governance.     

The odd log-logistic Lindley Poisson model for lifetime data

We define two new lifetime models called the odd log-logistic Lindley (OLL-L) and odd log-logistic Lindley Poisson (OLL-LP) distributions with various hazard rate shapes such as increasing, decreasing, upside-down bathtub, and bathtub. Various structural properties are derived. Certain characterizations of OLL-L distribution are presented. The maximum likelihood estimators of the unknown parameters are obtained. We propose a flexible cure rate survival model by assuming that the number of competing causes of the event of interest has a Poisson distribution and the time to event has an OLL-L distribution. The applicability of the new models is illustrated by means real datasets.     

Robust linear mixed models with skew-normal independent distributions from a Bayesian perspective

Linear mixed models were developed to handle clustered data and have been a topic of increasing interest in statistics for the past 50 years. Generally, the normality (or symmetry) of the random effects is a common assumption in linear mixed models but it may, sometimes, be unrealistic, obscuring important features of among-subjects variation. In this article, we utilize skew-normal/independent distributions as a tool for robust modeling of linear mixed models under a Bayesian paradigm. The skew-normal/independent distributions is an attractive class of asymmetric heavy-tailed distributions that includes the skew-normal distribution, skew-t, skew-slash and the skew-contaminated normal distributions as special cases, providing an appealing robust alternative to the routine use of symmetric distributions in this type of models. The methods developed are illustrated using a real data set from Framingham cholesterol study.     

COM–Poisson cure rate survival models and an application to a cutaneous melanoma data

In this paper, we develop a flexible cure rate survival model by assuming the number of competing causes of the event of interest to follow the Conway–Maxwell Poisson distribution. This model includes as special cases some of the well-known cure rate models discussed in the literature. Next, we discuss the maximum likelihood estimation of the parameters of this cure rate survival model. Finally, we illustrate the usefulness of this model by applying it to a real cutaneous melanoma data.     

Political Influence and the Performance of Nonprofit Spanish Banks

This article presents empirical evidence about factors that influence the solvency of Spanish savings banks. It also studies whether the presence of politicians in their governance has led to lower solvency ratios and, consequently, to the current economic situation in the Spanish banking sector. We use multivariate regressions, taking the solvency ratio as the dependent variable; and efficiency, the coverage ratio, political influence, CEOs’ political influence, size, growth, and age as independent variables. Our results confirm that banking entities controlled by politicians resulted in poor performance, and political influence on the boards of savings banks led them to insolvency. The findings show that the non‐ownership structure of savings banks, the lack of best practice corporate governance mechanisms, and political presence have weakened them.     

Bayesian analysis of skew-t multivariate null intercept measurement error model

The multivariate skew-t distribution (J Multivar Anal 79:93–113, 2001; J R Stat Soc, Ser B 65:367–389, 2003; Statistics 37:359–363, 2003) includes the Student t, skew-Cauchy and Cauchy distributions as special cases and the normal and skew–normal ones as limiting cases. In this paper, we explore the use of Markov Chain Monte Carlo (MCMC) methods to develop a Bayesian analysis of repeated measures, pretest/post-test data, under multivariate null intercept measurement error model (J Biopharm Stat 13(4):763–771, 2003) where the random errors and the unobserved value of the covariate (latent variable) follows a Student t and skew-t distribution, respectively. The results and methods are numerically illustrated with an example in the field of dentistry.     

A nonlinear regression model with skew-normal errors

In this paper we have discussed inference aspects of the skew-normal nonlinear regression models following both, a classical and Bayesian approach, extending the usual normal nonlinear regression models. The univariate skew-normal distribution that will be used in this work was introduced by Sahu et al. (Can J Stat 29:129–150, 2003), which is attractive because estimation of the skewness parameter does not present the same degree of difficulty as in the case with Azzalini (Scand J Stat 12:171–178, 1985) one and, moreover, it allows easy implementation of the EM-algorithm. As illustration of the proposed methodology, we consider a data set previously analyzed in the literature under normality.     

Environmental Consequences of the Community Support Framework 1994–99 in Spain

In this article we consider the energy and environmental implications of the extra GDP growth that the CSF, for the period 1994–99, is capable of entailing. In doing so, we have developed an illustration of the so-called three Es approach: economy–energy–environment. The extra growth induced by the CSF package and its incremental effects on energy consumption and CO₂ emissions have been evaluated against an energy–economy baseline provided by the HERMIN-Spain model and the Spanish energy plan (PEN). The most salient aspect of the analysis performed is that the energy-saving and emission-cutting margins embodied in the so-called PEN scenario (due to energy substitution and energy efficiency) are rapidly exhausted when growth accelerates, for example, due to a CSF like shock. However, these margins also reveal the promising prospects of progrowth strategies with high energy-efficiency content.
