Social Risk Factors in Spanish Youth and their Impact on Self-Concept Construction

El presente artículo aborda la relación existente entre juventud, trabajo y construcción de la identidad, desde perspectiva psicosocial. Los objetivos de la presente investigación fueron dos. En primer lugar, analizar la situación laboral de los jóvenes españoles y su impacto en la biografía de éstos. En segundo lugar, evaluar el papel de las variables laborales en la construcción / modificación de Determinados aspectos de la identidad de los jóvenes españoles. Para ello se utilizaron dos técnicas de recogida de información: la técnica Delphi (muestra de 103 expertos pertenecientes a distintas entidades y organizaciones con experiencia directa con el colectivo objeto de estudio) y entrevistas en profundidad (quince entrevistas distribuidas a lo largo de tres colectivos de jóvenes categorizados en función de su relación con el mercado laboral).This paper presents evidence from a psychosocial framework about the relationship among youth, work, and identity construction. The aims of this research were twofold. The first one was to analyze the working conditions of Spanish youth and their impact on individuals’ biographies. The second one was to examine the effect of labor-related variables on construction / change of identity elements in Spanish youth. For this purpose, two research techniques were used: the Delphi method (103 experts sample from several entities and organizations closely related to our topic) and deep interviews (15 interviews with youths classified according to their relationship with the work market)

Revisitando Gil-Pérez e colaboradores (2001): uma análise sobre a visão consensual da natureza da ciência

Ao final do último século, a Natureza da Ciência recebeu um papel de destaque dentro da área de Ensino de Ciências. Sua inserção no ensino é frequentemente justificada por sua relação com a alfabetização científica. É defendido por diversos autores que uma compreensão adequada da Natureza da Ciência contribui não apenas à alfabetização científica do indivíduo como também para sua formação como cidadão. Existem um grande número de vertentes e concepções da Natureza da Ciência e, dentre elas, destaca-se a chamada “visão consensual”, defendida por autores como Norman Lederman, William McComas e Daniel Gil-Pérez. No contexto brasileiro, popularizou-se no começo do século XXI um trabalho publicado pelo professor Gil-Pérez e seus colaboradores, contendo um levantamento de visões deformadas do trabalho científico e aspectos considerados consensuais da Natureza da Ciência. O objetivo deste trabalho foi analisar produções a respeito da Natureza da Ciência e os aspectos aparentemente consensuais que foram apresentados em trabalhos que são considerados fundamentais nessa área, em especial aqueles apresentados em Gil-Pérez et al. (2001) e, ao compará-los entre si e a trabalhos mais recentes, compreender a relevância da discussão de uma visão consensual da Natureza da Ciência para a área do Ensino de Ciências. Para este fim, foi realizada uma revisão bibliográfica sobre o assunto, assim como um levantamento dos artigos que utilizam Gil-Pérez et al. (2001) como referência através da plataforma Google Scholar. Os trabalhos foram divididos em 2 períodos para facilitar sua análise e após a organização e análise dos dados, através da Análise de Conteúdo, foi possível identificar pelo menos 4 categorias de trabalhos relacionados à Natureza da Ciência, com base nas citações à Gil-Pérez et al. (2001): 1) Investigação de Visões a respeito da Natureza da Ciência; 2) Críticas ou Propostas alternativas à Visão Consensual; 3) Relação entre a Natureza da Ciência e a História da Ciência; 4) Natureza da Ciência através de uma abordagem CTS. Concluímos afirmando que escolher a visão consensual ou outra abordagem depende do educador e um problema mais urgente a ser enfrentado seria o combate às visões inadequadas de Ciência.By the end of the last century, the Nature of Science was given a prominent role within Science Teaching. Its inclusion in this area is frequently justified by its relation to Scientific Literacy. It is advocated by several authors that an adequate comprehension of the Nature of Science not only contributes to the development of one’s scientific literacy as well as its development as a citizen. There are several strands and conceptions regarding the Nature of Science and, among them, the so called “consensus view” can be highlighted. This view is supported by authors such as Norman Lederman, William McComas and Daniel Gil-Pérez. In the brazilian context, a work published by the professor Daniel Gil-Pérez and his group got very popular in the beginning of the 21st century. It contained a survey of deformed views of the scientifical work and aspects considered consensual of the Nature of Science. The goal of this work was to analyze works regarding the Nature of Science and the apparently consensual aspects presented on works that are considered fundamental in this field, in special those presented in Gil-Pérez et al. (2001) and, when comparing them among themselves and to more recent works, to understand the relevance of discussing a “consensus view” of the Nature of Science to the field of Science Teaching. To this end, a literature review about the subject was made, as well as a research on the articles that use Gil-Pérez et al. (2001) as a reference, through the platform Google Scholar. The works were divided in 2 periods to favour its analysis and after the organization and analysis of the data, through the Content Analysis, we were able to identify 4 categories of works related to the Nature of Science, based on the references to Gil-Pérez et al. (2001): 1) Investigation of views on Nature of Science; 2) Criticism or Alternatives to the Consensus Views; 3) Relations between Nature of Science and History of Science; 4) Nature of Science through an STS approach. We conclude affirming that choosing between the consensus view or another approach depends on the educator and a more urgent problem to be faced would be to combat inadequate views of Science

A Phase I/II Trial of Oral SRA737 (a Chk1 Inhibitor) Given in Combination with Low-Dose Gemcitabine in Patients with Advanced Cancer

Gemcitabina; Cáncer avanzadoGemcitabina; Càncer avançatGemcitabine; Advanced cancerPurpose: This was a Phase I/II trial of the novel checkpoint kinase 1 (Chk1) inhibitor SRA737 given in combination with gemcitabine. Its objectives were to establish the safety profile, recommended Phase 2 dose (RP2D), pharmacokinetics profile, and clinical activity of SRA737. Patients and Methods: Patients with advanced solid tumors were enrolled into dose-escalation cohorts and treated in 28-day cycles with oral SRA737 on days 2, 3, 9, 10, 16, and 17, and intravenous gemcitabine on days 1, 8, and 15. Treatment was continued until progression. Each expansion cohort included up to 20 patients with specific genetically defined tumors. Results: The RP2D was determined to be 500 mg SRA737 combined with low-dose (250 mg/m2) gemcitabine. Of 143 enrolled patients, 77 were treated at doses of at least 500 mg SRA737 combined with 250 mg/m2 gemcitabine. Common toxicities of nausea, vomiting, fatigue, and diarrhea were primarily mild to moderate, and rarely led to treatment discontinuation. Anemia, neutropenia, and thrombocytopenia were grade ≥3 in 11.7%, 16.7%, and 10% of patients treated at the RP2D, respectively. The objective response rate (ORR) was 10.8% overall and notably the ORR in anogenital cancer was 25%. Partial tumor responses were observed in anogenital cancer, cervical cancer, high-grade serous ovarian cancer, rectal cancer, and small cell lung cancer. Conclusions: SRA737 in combination with low-dose gemcitabine was well tolerated with lower myelotoxicity than has been seen at standard doses of gemcitabine or with other combinations of Chk1 inhibitors with gemcitabine. Tumor responses were observed in anogenital and other solid tumors.The trial was sponsored by Sierra Oncology, Inc.

Verificando la integridad del registro arqueológico: análisis de fábricas en las unidades arqueológicas del paleolítico medio/superior de la Cova Gran (Santa Linya, Lleida)

L’anàlisi de fàbriques, és a dir, l’orientació i l’angle de cabussament dels objectes, constitueix una tècnica resolutiva en l’estudi dels processos de formació de jaciments. En aquest article presentem una síntesi de les principals aproximacions realitzades al voltant d’aquesta tècnica d’anàlisi aplicada durant els últims anys en conjunts arqueològics, així com la seva aplicació en el cas dels nivells de la transició paleolític mitjà/superior de la Cova Gran. Tal metodologia s’integra en el nostre mètode d’excavació, que hem sistematitzat al llarg dels anys amb el desenvolupament de models teòrics i aplicacions tecnològiques (Mora, 1994; Martínez-Moreno et al., 2011). Aportant noves dades a estudis previs, es comparen les fàbriques sedimentàries enfront de les arqueològiques dels nivells mencionats, i afloren diferències significatives entre aquests dos tipus de fàbriques. Aquestes observacions, conjuntament amb altres atributs, denoten processos de formació diferenciats que assenyalen la incidència de l’activitat humana en els processos tafonòmics dels artefactes arqueològics, així com una escassa incidència de pertorbacions sin/postdeposicionals en aquest tram de la seqüència de la Cova Gran.Fabric analysis, that is the study of orientation and slope of the objects, constitutes a resolving technique in the study of site formation processes. In this paper we present a synthesis of the different approaches undertaken around this technique applied during the last years in archaeological contexts, and it application in the case of Middle/Upper Paleolithic levels of Cova Gran. This methodology is integrated in our excavation method that we have systematized along the last years with the development of theoretical models and technological applications (Mora 1994, Martínez-Moreno et al. 2011). We provide new data to previous studies through the comparison of sedimentary fabrics vs. archaeological fabrics of the mentioned levels and, with this procedure, significant differences arise between both fabric types. These observations, along with other features, reflect to differentiated formation processes that point to the human activity incidence in the taphonomic processes of the archaeological artifacts and the scarce incidence of syn/post-depositional disturbances in this part of Cova Gran archaeological sequence.El análisis de fábricas, es decir, la orientación y el ángulo de buzamiento de los objetos, constituye una técnica resolutiva en el estudio de los procesos de formación de yacimientos. En este artículo presentamos una síntesis de las principales aproximaciones realizada alrededor de esta técnica de análisis aplicada en los últimos años en conjuntos arqueológicos, así como su aplicación en el caso de los niveles de la transición paleolítico medio/superior de la Cova Gran. Dicha metodología se integra en nuestro método de excavación, que hemos sistematizado a lo largo de los años con el desarrollo de modelos teóricos y aplicaciones tecnológicas (Mora, 1994; Martínez- Moreno et al., 2011). Aportando nuevos datos a estudios previos, se comparan las fábricas sedimentarias frente a las arqueológicas de dichos niveles, hallando diferencias significativas entre estos dos tipos de fábricas. Tales observaciones, junto con otros atributos, denotan procesos de formación diferenciados que señalan la incidencia de la actividad humana en los procesos tafonómicos de los artefactos arqueológicos así como una escasa incidencia de perturbaciones sin/postdeposicionales en este tramo de la secuencia de la Cova Gran

La aplicación de los códigos Data Matrix (DM) en el registro y la catalogación arqueológica

El registro e inventariado de los materiales arqueológicos es una parte esencial de la investigación arqueológica. Durante el trabajo de laboratorio, cada ítem es identificado individualmente. Esta tarea se realiza generalmente a mano, lo que facilita la pérdida de información debido a errores humanos. De este modo, números erróneos, ortografía ilegible o la desaparición del identificador de los artefactos son comunes. Ante la ausencia de un método fiable y duradero de marcado de los objetos, una parte importante del trabajo en los museos consiste en el re-inventariado de las colecciones. En este trabajo se presenta la utilización de los códigos Data Matrix (DM) para el catalogado del material arqueológico. Su uso en los yacimientos de Roca dels Bous y la Cova Gran de Santa Linya (Lleida, España) evidencia que la aplicación de esta técnica facilita el almacenaje y preservación de las colecciones arqueológicas.El registre i inventari del material arqueològic es una part essencial de la recerca arqueològica. Al llarg del treball de laboratori cada objecte és identificat individualment. Aquesta tasca es realitza generalment a mà, fet que facilita la pèrdua d'informació a causa d'errors humans. D'aquesta manera números erronis, ortografia illegible o la desaparició de l'identificador són molt comuns. Davant l'absència d'un mètode fiable de marcatge, una part important del treball als museus consisteix en el reinventariat de les col·leccions. En aquest treball es presenta la utilització dels codis Datamatrix (DM) en el catalogat del material arqueològic. El seu ús als jaciments de Roca dels Bous i la Cova Gran de Santa Linya (Lleida, Espanya) evidencia que l'aplicació d'aquesta nova tècnica facilita l'emmagatzematge i la preservació de col·leccions arqueològiques.The recording and inventory of archaeological material is a key point in archaeology. During laboratory duties, each item is individually identified and labelled. This task is usually by hand, which facilitates the information loss due to human error. Thus wrong numbers, misspelling or id loss are common. The lack of a reliable method of marking leads to allocate most of museum tasks to the relabelling of collections. In this paper we present the application of DataMatrix (DM) codes for archaeological labelling. The application of DM in Roca dels Bous and Cova Gran Santa Linya (Lleida Spain) rockshelters has shown that this technique facilitates the storage and preservation of the archaeological collections

Carrying rocks : Hoarding behaviour in the Gravettian occupation of Cova Gran de Santa Linya (SE Pyrenees)

Altres ajuts: Acord transformatiu CRUE-CSICCova Gran de Santa Linya is part of the project Human settlement during the Upper Pleistocene and Holocene in the Southeastern Pyrenees (PID 2019-104843GB-I00) and the 2017SGR-1357 research group. This research has been also supported by MINECO-FPU scholarships. Fieldwork was funded by Servei d'Arquelogia I Paleontologia from the Generalitat de Catalunya (CLT009/18/00012). We thank the support given by the Institute for Field Research, all volunteers that participate in the fieldwork, and the kind permission of the Societat de Munts de Santa Linya to authorize the excavation in Cova Gran.Lithic resources can be accumulated to form caches or hoards as an effective subsistence strategy in response to times of stress. Hoarding behaviour is the manifestation of foresighted mechanisms, and is one of the common and also little known strategies among forager groups. In this paper, we present the evidence of such behaviour: a deposit of raw material recovered from level 497C of the Cova Gran de Santa Linya (SE Pyrenees). The lithic hoard is made up of 27 chalcedony nodules that have been tested at the site and exhibit great variability in terms of size and shape. The geostatistical analysis applied to the accumulations of raw materials identified has allowed us to determine spatial relationships between different categories in the archaeological record, such as nodules and cores, and has yielded insight into the use of chalcedony in specific areas of the occupation. The archaeological data suggest that this stockpile of raw material functioned as small-scale storage, constituting one of the few references about hoarding behaviour during the Palaeolithic, and the first time it has been exhaustively described in the Gravettian on the Iberian Peninsula. The lithic hoard from the Cova Gran allows us to investigate the role played by raw material hoards in the planning of subsistence activities and the organisation of human occupations
