Socioeconomic segregation of students
School segregation may be questioning the equity of the Spanish educational system. In this research, we analyse the school segregation by socioeconomic status using the Hutchens Index. Specifically, we decompose the effect of attending public vs semiprivate schools in terms of segregation. The analyses is based on data collecting information from the population of Andalusian students attending 5th grade. We found significant differences in the level of segregation between both schools types. Particularly, the results show that students from high socioeconomic and cultural status are more segregated in public schools, while students from a low socioeconomic and cultural status are more segregated in semiprivate schools. These differences provide evidence of the inequity of the education policy, which should rethink funding mechanisms as a means to fight against inequality.Universidad de Málaga.

Resultats preliminars de l'excavació arqueològica a la Casa Masferrer (Vic, Osona)
L'excavació arqueològica a la Casa Masferrer ha posat en evidència la continuïtat d'ocupació humana en un dels punts més elevats de la ciutat fortificada de Vic. La presència d'un nivell de circulació d'època romana juntament amb diverses estructures i espais d'activitat d'època medieval i època moderna ens aporten informació cabdal per comprendre la gestió i els usos dels espais de l'entorn del temple romà, posteriorment del Palau dels Montcada, al llarg dels segles

Q-SEA - a tool for quality assessment of ethics analyses conducted as part of health technology assessments
Introduction: Assessment of ethics issues is an important part of health technology assessments (HTA). However, in terms of existence of quality assessment tools, ethics for HTA is methodologically under-developed in comparison to other areas of HTA, such as clinical or cost effectiveness.Objective: To methodologically advance ethics for HTA by: (1) proposing and elaborating Q-SEA, the first instrument for quality assessment of ethics analyses, and (2) applying Q-SEA to a sample systematic review of ethics for HTA, in order to illustrate and facilitate its use. Methods: To develop a list of items for the Q-SEA instrument, we sys-tematically reviewed the literature on methodology in ethics for HTA, reviewed HTA organizations’ websites, and solicited views from 32 ex-perts in the field of ethics for HTA at two 2-day workshops. We sub-sequently refined Q-SEA through its application to an ethics analysis conducted for HTA.Results: Q-SEA instrument consists of two domains – the process do-main and the output domain. The process domain consists of 5 ele-ments: research question, literature search, inclusion/exclusion criteria, perspective, and ethics framework. The output domain consists of 5 elements: completeness, bias, implications, conceptual clarification, and conflicting values.Conclusion: Q-SEA is the first instrument for quality assessment of ethics analyses in HTA. Further refinements to the instrument to enhance its usability continue
Skin-Derived Precursor Cells as an In Vitro Modelling Tool for the Study of Type 1 Neurofibromatosis
The most characteristic feature of neurofibromatosis type 1 (NF1) is the development of neurofibromas. It has been suggested that these tumors are caused by somatic inactivation of the wild-type NF1 allele, but the cell that originally suffers this mutation remains controversial. Several lines of evidence support the clonal origin of these tumors, and it has been recently suggested that skin-derived precursor cells (SKPs) could be the cell of origin of dermal neurofibromas. Nullizygous (NF1−/−) SKPs do give rise to neurofibromas when transplanted to heterozygous mice. Moreover, a nullizygous population of cells that is S100β negative is present in human neurofibromas, and NF1+/− multipotent progenitor cells are seemingly recruited to the tumor. This evidence supports the neurofibroma stem cell hypothesis and a putative involvement of SKPs in the aetiopathogenesis of the disease, suggesting that SKPs could become a valuable tool for the in vitro study of NF1
Towards interoperability of i* models using iStarML
Goal-oriented and agent-oriented modelling provides an effective approach to the understanding of distributed information
systems that need to operate in open, heterogeneous and evolving environments. Frameworks, firstly introduced more than ten
years ago, have been extended along language variants, analysis methods and CASE tools, posing language semantics and tool interoperability issues. Among them, the i* framework is one the most widespread. We focus on i*-based modelling languages and tools and on the problem of supporting model exchange between them. In this paper, we introduce the i* interoperability problem and derive an XML interchange format, called iStarML, as a practical solution to this problem. We first discuss the main requirements for its definition, then we characterise the core concepts of i* and we detail the tags and options of the interchange format. We complete the presentation of iStarML showing some possible applications. Finally, a survey on the i* community perception about iStarML is included for assessment purposes.Preprin
