Se ha destacado recientemente que la Fórmula de Barcan (FB) y la Conversa de la Fórmula de Barcan (CFB) para lógica modal cuantificacional de orden superior parecen válidas. Si se interpreta que los cuantificadores tienen como rango propiedades, la validez de (FB) y (CFB) de orden superior parece implicar la existencia de universales trascendentes, esto es, universales que no requieren estar instanciados para existir en un mundo posible. Este trabajo discute esta línea de argumentación. En primer lugar, se sostiene que la semántica en la que los resultados de validez se siguen no requiere que las �intensiones� asignadas a las variables de orden superior estén instanciadas en un mundo posible para que la intensión exista ahí. El defensor de universales inmanentes objetaría esta suposición. En una semántica modificada, más neutral, (FB) y (CFB) de orden superior ya no son válidas. En segundo lugar, se sostiene que, incluso si se concediese la validez de (FB) y (CFB) de orden superior, no se obtendrían resultados metafísicos sustantivos, pues diferentes formas de nominalismo y diferentes teorías de tropos no tendrían dificultades en aceptar (FB) y (CFB) de orden superiorDate

The decision not to initiate breastfeeding--women's reasons, attitudes and influencing factors--a review of the literature.Atchan, M; Foureur, M; Davis, D (2014-04-03)Breastfeeding is the biological feeding norm for human babies. Encouraging breastfeeding is a primary health promotion strategy, with studies demonstrating the risks of artificial baby milks. Each year approximately 10% of the women who give birth in New South Wales decide not to initiate breastfeeding, and the demographic characteristics of this group of women have previously been identified. This paper reviews the literature to explore the factors that influence women's decisions about breastfeeding, and their reasons for not initiating breastfeeding. The review revealed there are relatively few studies that explore the experiences of women who decide not to initiate breastfeeding, especially in the Australian context.

Ex-Ante Methods to Assess the Impact of Social Insurance Policies on Labor Supply with an Application to BrazilZylberstajn, Helio; Robalino, David A. (2012-03-19)This paper solves and estimates a
 stochastic model of optimal inter-temporal behavior to
 assess how changes in the design of the unemployment
 benefits and pension systems in Brazil could affect savings
 rates, the share of time that individuals spend outside of
 the formal sector, and retirement decisions. Dynamics
 depend on five main parameters: preferences regarding
 consumption and leisure, preferences regarding formal Vs.
 informal work, attitudes towards risks, the rate of time
 preference, and the distribution of an exogenous shock that
 affects movements in and out of the social security system
 (given individual decisions). The yearly household survey is
 used to create a pseudo panel by age-cohorts and estimate
 the joint distribution of model parameters based on a
 generalized version of the Gibbs sampler. The model does a
 good job in replicating the distribution of the members of a
 given cohort across states (in or out of the social security
 / active or retired). Because the parameters are related to
 individual preferences or exogenous shocks, the joint
 distribution is unlikely to change when the social insurance
 system changes. Thus, the model is used to explore how
 alternative policy interventions could affect behaviors and
 through this channel benefit levels and fiscal costs. The
 results from various simulations provide three main
 insights: (i) the Brazilian SI system today might generate
 distortions (lower savings rates and less formal employment)
 that increase the costs of the system and might generate
 regressive redistribution; (ii) there are important
 interactions between the unemployment benefits and pension
 systems, which calls for joint policy analysis when
 considering reforms; and (iii) current distortions could be
 reduced by creating an actuarial link between contributions
 and benefits and then combining matching contributions and
 anti-poverty targeted transfers to cover individuals with
 limited or no savings capacity.

Republic of Niger : Towards an Integrated and Sustainable Pension SystemWorld Bank (Washington, DC, 2014-07-17)This report was prepared at the request
 of the Government of Niger to: (i) provide a comprehensive
 assessment of the Nigerien pension system, (ii) analyze
 current reform initiatives and recommend possible
 refinements and alternatives, and (iii) examine
 implementation challenges. To this end, the report develops
 a set of general guidelines to assess reform options in
 terms the adequacy of benefits, security, financial
 sustainability, redistribution, incentives, and
 administrative efficiency. The core of the report is
 organized in three chapters. After providing a summary of
 the background (chapter one), chapter two develops the
 policy framework and updates the assessment of the mandatory
 pension systems. The assessment looks at the financial
 situation of the schemes but also discusses other problems
 that had been previously overlooked in terms of the adequacy
 of benefits; the type of redistribution; as well as issues
 related to incentives. Chapter three reviews Government
 ongoing reform initiatives, summarizes the international
 experiences that are relevant to Niger, and, presents
 recommendations to strengthen current policies by outlining
 the components of a multi-year reform program, and
 developing a road map towards implementation.
