Estudio sobre la Belleza traicionada: la teoría estética y el desconocimiento del art

The Implication of Images in the Revival of Aesthetics

Contemporary aesthetic theory is embedded in a culture dominated by images, and so would seem to require a reversal of Plato's critique of image-making. In adopting this stance, aesthetic theory follows in the footsteps of Nietzsche, whose own project was conceived as a reversal of Platonism. But the critique of Plato that underpins these views is based on a tradition that has misconstrued some of Plato's fundamental ideas. For this reason, the standard critique of Platonism is ineffective as a critical response to the culture of images. Aesthetic theory needs instead to produce a critique of the contemporary image-world based on the view that it emerges from a transformation in the paradigm of production. Images are no longer merely a part of the world that is produced, but themselves have a crucial role in the process of production

The Impact of Early Childbirth on Socioeconomic Outcomes and Risk Indicators of Females Transitioning Out of Foster Care

Few studies have documented the relationship between early childbirth and the adjustment of females transitioning out of foster care. In this study, data from the National Youth in Transition Database were used to evaluate the associations between childbirth at three time points (prior to age 17, ages 17–19, and ages 19–21) and females’ socioeconomic outcomes and risk indicators at age 21 (n = 3173). Findings revealed that over 40% of females had given birth at least once by age 21, with a substantial increase in birth rates from adolescence to early adulthood. Multivariate analyses showed that childbirth between ages 17 and 19 and between ages 19 and 21 was associated with decreased likelihood of obtaining a high school diploma/GED or higher. However, only most recent childbirth (between ages 19 and 21) was associated with decreased likelihood of employment and increased likelihood of receiving public assistance. Contrary to the hypothesis, childbirth was unrelated to homelessness, substance abuse referrals and incarceration at age 21, once earlier presence of such risks was taken into account. Overall, while childbirth between ages 19 and 21 was linked to negative socioeconomic outcomes as females entered young adulthood, earlier births did not appear to confer a unique, prospective risk for the majority of the variables studied. These findings underscore the importance of expanding specialized services designed to promote educational and vocational opportunities for young mothers transitioning out of foster care, especially in the first years following childbirth. The importance of targeting foster youth for pregnancy prevention programs will also be discussed

Ann-based model for the prediction of the bond strength between frp and concrete

In the last decades, the uses of fiber reinforced polymer (FRP) composites in the structural strengthening of reinforced concrete (RC) structures have become the state of the art, providing a valid alternative to the traditional use of steel plates. These relatively new materials present, in fact, great advantages, including high corrosion resistance in aggressive environments, low specific weight, high strength-to-mass-density ratio, magnetic and electric neutrality, low axial coefficient of thermal expansion and sustainable costs of installation. In flexural and shear strengthening of RC members, the effectiveness of the epoxy bonded FRP strongly depends on the adhesion forces exchanged with the concrete substrate. When the flexural moment is present, the FRP strengthening is activated through the stress transfer on the tension side, which is guaranteed by the contact beam region to which the adhesive is bonded to the beam itself. Hence, the determination of the maximum forces that cause debonding of the FRP-plate becomes crucial for a proper design. Over the years, many different analytical models have been provided in the scientific literature. Most of them are based on the calibration of the narrow experimental database. Now, hundreds of experimental results are available. The main goal of the current study is to present and discuss an alternative theoretical formulation for predicting the debonding force in an FRP-plate, epoxy-bonded to the concrete substrate by using an artificial neural networks (ANNs) approach. For this purpose, an extensive study of the state of the art, reporting the results of single lap shear tests, is also reported and discussed. The robustness of the proposed analytical model was validated by performing a parametric analysis and a comparison with other existing models and international design codes, as shown herein

Seismic capacity estimation of a masonry bell-tower with verticality imperfection detected by a drone-assisted survey

Masonry towers are considered an important part of cultural heritage due to their architectural and historical value. From a structural perspective these kind of buildings are considered slender elements, the same as a cantilever beam. In real cases it is not easy to model with high accuracy these heritage constructions, since the geometry and mechanical properties of the constituent materials are not adequately known. On the other hand, a deep knowledge of the structural and seismic vulnerability of the masonry towers is needed in order to preserve and retrofit, when necessary, their architectural and cultural value. In the present research an exhaustive study is presented, as it regards the assessment of the seismic vulnerability of a heritage masonry bell-tower, built in the 14th century. An innovative protocol of structural survey followed, and it is proposed herein. The geometry of the tower was easily obtained by digital photogrammetry assisted by a drone. The geometrical model was easily converted into a digitalized input, that was introduced into a finite element method (FEM)-based code. The 3D model was used for linear static, linear dynamic and nonlinear static (pushover) structural analyses. The vulnerability of the masonry tower was assessed and at least one kinematic was found to be not verified

Where Have We Been and Where Are We Going? A Conceptual Framework for Child Advocacy

The primary goal of this article is to chart the development of child advocacy as an interdisciplinary field of study and conclude with a conceptual framework for research and higher education in child advocacy. Historically, child advocacy has justifiably focused on protection needs. Values and assumptions about children\u27s best interest have also governed child advocacy, in part because evidence to inform decisions was lacking and in part because of its history as an activist movement. Against this historical backdrop, we describe contemporary trends in child advocacy that reconcile children\u27s protection with their inherent rights to personhood. We rely on the principles and articles of the United Nations Convention on the Rights of the Child, most notably children\u27s rights to participation and self-expression. At the same time, we demonstrate how values and ideology are being integrated with empiricism and objective analysis to inform policy and practice in child advocacy. The future of child advocacy depends on continued synthesis of rights and protection as well as values and rigorous analysis. From this perspective, we offer a conceptual framework for research and education in child advocacy
