La cuestión del relativismo cultural

La actualidad de la temática sobre el RELATIVISMO CULTURAL es obvia. En determinadas ciencias sociales funciona, de hecho, como un supuesto intocable. El presente artículo pretende cuestionar dicho presupuesto intentando delimitar el sentido aceptable en su aplicabilidad. A tal efecto hemos compulsado diversos puntos de vista de diferentes y relevantes expertos sobre esta cuestión: I. Kant, R. Dawkins, M. Weber, J. Habermas, R, Rorty, etc. Y, también, hemos dado nuestra opinión.The current importance of the subject matter on the cultural relativism is obvious. In certain social sciencies it works of fact as an untouchable supposition. The present article tries to question presupposed saying trying to delimit the aceptable sense in its aplicabilidad. To such an effect we have collated diverse points of view of different and relevant expert in this question: I. Kant, R. Dawkins, M. Weber, J.

A Retrospective View of Software Maintenance and Reengineering Research.

As a summary of past, current, and future trends in software maintenance and reengineering research, we give in this editorial a retrospective look from the past 14 years to now. We provide insight on how software maintenance has evolved and on the most important research topics presented in the series of the European Conference on Software Maintenance and Reengineering

Extending Software Architecting Processes with Decision-making Activities 1

Abstract. The traditional perspective on software architecture has paid much attention to architecting as a development process aimed at creating the architecture of a software system, as well as the documentation used to communicate the architecture to the stakeholders by means of several architectural views. Recently, the software architecture research community has faced the need to record, manage, and document the design decisions and the rationale that lead to such architecture. Because architectures are the result of a set of design decisions, this design rationale must be properly recorded and managed as a complementary process to the modelling activity. In this paper we detail different types of decision-making activities aimed at creating and using design decisions and how these can be supported with tool support

Assessment of the Refractive Index and Extinction Coefficient of Graphene-Poly(3-hexylthiophene) Nanocomposites

Poly(3-hexylthiophene) (P3HT) is one of the most attractive polymeric donor materials used in organic solar cells because of its high electrical conductivity and solubility in various solvents. However, its carrier mobility is low when compared to that of inorganic semiconductors; hence, the incorporation of appropriate nanomaterials to improve its electrical mobility and optical properties are pursued. In this work, a review of the changes in electrical conductivity, bandgap, hole collection properties and carrier mobility of P3HT when adding graphene (G) is presented. The main aim is to assess how the addition of different G contents influences the optical constants: refractive index (n) and extinction coefficient (k). The values of n and k as a function of the wavelength for six P3HT/G nanocomposites with G loadings in the range of 0.1-5 wt% have been fitted to two different models, Forouhi Bloomer and Cauchy, showing very good agreement between the experimental and the theoretical values. Furthermore, a rule of mixtures was successfully applied to calculate n using mass fraction instead of volume fraction, with errors lower than 6% for all the nanocomposites studied

Application of graphene-related materials in organic solar cells

Graphene-related materials (GRMs) such as graphene quantum dots (GQDs), graphene oxide (GO), reduced graphene oxide (rGO), graphene nanoribbons (GNRs), and so forth have recently emerged as photovoltaic (PV) materials due to their nanodimensional structure and outstanding properties such as high electrical and thermal conductivity, large specific surface, and unique combination of mechanical strength and flexibility. They can be a crucial part of transparent electrodes, hole/electron transport materials, and active layers in organic solar cells (OSCs). Besides their role in charge extraction and transport, GRMs act as device protectors against environmental degradation through their compact bidimensional structure and offer good durability. This review briefly presents the synthesis methods of GRMs and describes the current progress in GRM-based OSCs. PV parameters (short circuit current, open circuit voltage, power conversion efficiency, and fill factor) are summarized and comparatively discussed for the different structures. The efficiency recently surpassed 15% for an OSC incorporating polymer-modified graphene as a transparent electrode. The long-term stability of OSCs incorporating GRMs is also discussed. Finally, conclusions and the outlook for future investigation into GRM-based devices for PVs are presented

Automating the deployment of componentized systems

Embedded and self-adaptive systems demand continuous adap- tation and reconfiguration activities based on changing quality condi- tions and context information. As a consequence, systems have to be (re)deployed several times and software components need to be mapped onto new or existing hardware pieces. Today, the way to determine an optimal deployment in complex systems, often performed at runtime, constitutes a well-known challenge. In this paper we highlight the major problems of automatic deployment and present a research plan to reach for an UML-based solution for the deployment of componentized sys- tems. As a first step towards a solution, we use the UML superstructure to suggest a way to redeploy UML component diagrams based on the inputs and outputs required to enact an automatic deployment process.Comisión Interministerial de Ciencia y Tecnología (CICYT) SETI (TIN2009-07366
