Este trabajo analiza las nuevas tendencias en la creación y gestión de información geográfica, para la elaboración de modelos inductivos basados exclusivamente en bases de datos geográficas. Estos modelos permiten integrar grandes volúmenes de datos de características heterogéneas, lo que supone una gran complejidad técnica y metodológica. Se propone una metodología que permite conocer detalladamente la distribución de los recursos hídricos naturales en un territorio y derivar numerosas capas de información que puedan ser incorporadas a estos modelos «ávidos de datos» (data-hungry). La zona de estudio escogida para aplicar esta metodología es la comarca de la Marina Baja (Alicante), para la que se presenta un cálculo del balance hídrico espacial mediante el uso de herramientas estadísticas, geoestadísticas y Sistemas de Información Geográfica. Finalmente, todas las capas de información generadas (84) han sido validadas y se ha comprobado que su creación admite un cierto grado de automatización que permitirá incorporarlas en análisis de Minería de Datos más amplios.

Aquest treball s'enquadra dintre de la disciplina de l'adquisició del llenguatge, encarregada d'estudiar els diferents processos que l'ésser humà du a terme en el desenvolupament de la parla. En aquest cas, s'estudiarà l'adquisició del subjecte nul en català, i es partirà de la següent qüestió: els xiquets catalanoparlants menors de 5 anys, han fixat correctament el paràmetre del subjecte nul? Per resoldre aquesta qüestió, partirem de la hipòtesi del VEPS (Very Early Parmeter Settings), que afirma que els paràmetres (una de les dimensions de la variació estructural del llenguatge humà) es fixen abans de l'estadi de dues paraules. Per realitzar l'estudi, comptabilitzarem els subjectes nuls en frases subordinades i no subordinades per a 4 adults i 8 xiquets parlants del català, material que extraurem de la base de dades CHILDES. Finalment compararem els nostres resultats amb els de l'anglés de Valian (1991), llengua que no admet l'omissió de subjecte.

L’etnopoètica, entesa com «la branca del folklore que estudia l’art verbal» és, sens dubte, una disciplina emergent en l’àmbit dels estudis filològics catalans. Arran de la creació del Grup d’Estudis Etnopoètics, auspiciat l’any 2004 per diversos investigadors de la Universitat Rovira i Virgili de Tarragona, la Universitat d’Alacant i la Universitat de les Illes Balears, hi hem assistit en les últimes dues dècades a un contumaç procés de reivindicació, dignificació, modernització, sistematització, planificació, institucionalització, coordinació, producció, difusió, internacionalització i —en definitiva— vivificació d’estudis que paren atenció al complex univers de la literatura popular de transmissió oral.

In marmosets, it was observed that the synchrony among circadian activity profiles of animals that cohabite in family groups is stronger than those of the same sex and age of different families. Inside the group, it is stronger between the younger ones than between them and their parents. However, the mechanisms involved in the social synchrony are unknown. With the aim to investigate the synchronization mechanisms involved in the synchrony between the circadian activity profiles during cohabitation in pairs of marmosets, the motor activity was continuously registered by the use of actmeters on three dyads. The pairs were maintained in two different conditions of illumination: light-dark cycle LD 12:12 (LD cohabitation I – 21 days), and thereafter in LL (~350 lux). Under LL, the pairs were submitted to four experimental situations: 1. Cohabitation (LLJ I – 24 days), 2. Removal of one member of the pair to another room with similar conditions (LLS I – 20 days), 3. Reintroduction of the separated member in the cage of the first situation (LLJ II – 30 days) and 4. Removal of a member from each pair to another experimental room (LLS II – 7 days), to evaluate the mechanisms of synchronization. Ultimately, the members of each pair were reintroduced in the cage and were kept in LD cycle 12:12 (LDJ II – 11 days). The rhythms of pairs free-ran in LL, with identical periods between the members of each pair during the two stages of cohabitation. In the stages in which the animals were separated, only the rhythms of two females free-ran in the first stage and of three animals in the second one. In those conditions, the rhythms of animals of each pair showed different endogenous periods. Besides, during cohabitation in LD and LL, the members of each pair showed a stable phase relationship in the beginning of the active phase, while in the stages in which the animals were separated it was noticed a breaking in the stability in the phase relationships between the circadian activity profiles, with an increase in the difference in the phase angles between them. During cohabitation, at the transition between LD and LL, all animals showed free-running rhythms anticipating progressively the beginning and the end of the active phase in a phase similar to the previous condition, showing signs of entrainment to the previous LD. While in the posterior stages this was observed in only three animals between: LLT I and LLS I, and LLT II and LLS II, evidencing signs of entrainment to social cues between the members of each pair. On the other hand, one animal delayed progressively between LLT I and LLS I, three animals delayed between LLS I and LLT II, and three animals between LLT II and LLS II, perhaps by entrainment to the animals maintained outdoors in the colony. Similar process was observed in four animals between LLS II and LDT II, indicating entrainment to LD. In the transition between LLS I and LLT II, signs of masking was observed in the rhythm of a female in response to the male and in another pair in the rhythm of the male in regard to that of the female. The general and maximum correlations in the circadian activity profiles were stronger during cohabitation in LD and LL than in the absence of social contact in LL, evidencing the social effect. The cohabiting pairs had higher values of the maximum correlation in LD and LL than when the profiles were correlated to animals of different cages, with same or different sexes. Similar results were observed in the general correlation. Therefore, it is suggested that cohabitation induces a strong synchrony between circadian activity profiles in marmosets, which involves entrainment and masking. Nevertheless, additional studies are necessary to evaluate the effect of social cues on the synchronization of the circadian rhythm in pairs of marmosets in the absence of external social cues in order to confirm this hypothesis.

El Periodismo de Datos se ha convertido en una de las tendencias que se están implantando en los medios. En pocos años el desarrollo y visibilidad de esta modalidad ha aumentado considerablemente y son numerosos los medios que cuentan con equipos y espacios específicos de Periodismo de Datos en el panorama internacional. Del mismo modo, existen aplicaciones, plataformas, webs, o fundaciones al margen de las empresas periodísticas cuya labor también puede ser enmarcada en este ámbito. El objetivo principal de esta contribución es establecer una radiografía de la implantación del Periodismo de Datos en España; tanto dentro como fuera de los medios. Aunque se trata de una disciplina todavía en fase de desarrollo, parece adecuado realizar un estudio exploratorio que ofrezca una panorámica de su situación actual en España.

Algumas pesquisas demonstram que a presença de um parceiro social durante uma situação de risco modula a resposta ao estresse, atenuando seus efeitos negativos. Neste estudo, 8 díades de machos e 8 de fêmeas de sagüi comum (Callithrix jacchus) foram expostos a um ambiente novo, sozinhos e acompanhados de um parceiro de mesmo sexo e idade. Quando submetidos a um ambiente novo em companhia de um animal de mesmo sexo, os machos apresentaram um perfil mais filiativo enquanto as fêmeas foram mais competitivas entre si. Os resultados mostram que a resposta comportamental é sexualmente dimórfica, e que machos e fêmeas utilizam diferentes estratégias quando confrontados com situações desafiadoras no ambiente natural Abstract Some researches demonstrate that the presence of a social partner during a challenging situation modulates the stress response, decreasing its negative effects. In this study common marmoset (Callithrix jacchus) males and females were exposed to a new environment, alone or in companion of a social partner of the same sex and age. When submitted to new environment in companion of a same-sex social partner males showed more affiliation whereas females performed agonistic behaviors. The results show that behavioral response is sexually dimorphic and that males and females used different strategies when facing challenging situations in natural conditions

Introdução. Os estilos educativos parentais enquanto clima educativo geral apresentam um forte impacto em diferentes resultados desenvolvimentais (e.g., sintomatologia depressiva/ansiosa e auto estima) da criança/jovem. Podem ser estudados de um ponto de vista dimensional, considerando, por exemplo, as dimensões Controlo/Sobreproteção e Suporte, ou categorial, seguindo, por exemplo, a abordagem de Baumrind, e Maccoby e Martin. Neste estudo pretendemos: verificar se existem diferenças por género e idade, nas dimensões Suporte Emocional, Sobreproteção e Rejeição (EMBU-A) (cada progenitor separadamente), na sintomatologia depressiva/ansiosa e na auto estima; avaliar se existem diferenças nas dimensões do EMBU-A, entre progenitores, na amostra total e por género; explorar associações entre as variáveis centrais do estudo (estilos educativos, sintomatologias e auto estima) e variáveis sociodemográficas, também nas três amostras; explorar diferenças entre quatro grupos criados (Pai-Filho, Pai-Filha; Mãe-Filho e Mãe-Filha) nas dimensões do EMBU-A; combinando a Sobreproteção e o Suporte Emocional (EMBU-A), e definindo os estilos educativos parentais autoritário, autoritativo, permissivo e negligente, calcular a prevalência dos mesmos na nossa amostra (por Pai e por Mãe) e explorar as suas associações com as sintomatologias e com a auto estima (separadamente, por progenitor). Metodologia. A nossa amostra é constituída por 284 adolescentes (idade média = 14,5; DP = 1,68; raparigas, n = 171, 60,2%). Todos preencheram um protocolo composto por um questionário sociodemográfico, pela Rosenberg Self- Esteem Scale (RSES), pelo DASS-21 e pelo Parental Rearing Style Questionnaire for use with Adolescents (EMBU-A/A). Resultados. De salientar o facto de os adolescentes percecionarem a mãe como apresentando valores mais elevados em todas as dimensões do EMBU-A, por comparação com o pai. Da mesma forma, ainda que com diferentes padrões de associação conforme o género, é de salientar a associação entre níveis maiores de Suporte emocional e níveis mais baixos de sintomatologia depressiva/ansiosa e stress, e a associação entre as dimensões Sobreproteção e Rejeição e níveis superiores desses resultados. Uma mais baixa escolaridade do pai associa-se a menor Suporte emocional e uma maior escolaridade da mãe a maior Sobreproteção. Uma díade constituída por progenitor e adolescente do género masculino apresenta resultados inferiores em todas as dimensões do EMBU-A, por comparação com díades formadas por mãe-filho/filha. O estilo Autoritativo é o mais prevalente na nossa amostra (em ambos os progenitores) e o estilo Autoritário é aquele que se associa a pontuações mais elevadas de psicopatologia e a uma menor auto estima. Discussão. De uma forma, genérica os resultados seguem de perto a literatura e revelam a associação entre valores mais elevados na dimensão Suporte emocional e níveis mais baixos de psicopatologia e stress, e a associação entre as dimensões Sobreproteção e Rejeição e níveis superiores desses resultados. Igualmente, o estilo educativo Autoritário está claramente associado a piores resultados nessas mesmas variáveis. São discutidas algumas implicações, no que toca a programas psicoeducativos/educação parental. / Introduction. As a general educational environment, parental rearing styles have a strong impact in different outcomes of development of the child or teenager (e.g. symptoms of depression/ anxiety and self-esteem). These can be studied from a dimensional point of view considering for example the dimensions Control/Overprotection and Support or from a categorical point of view following for example the approach of Baumrind and Maccoby and Martin. This study aims at checking whether there are differences of gender and age in the dimensions of Emotional Support, Overprotection and Rejection (EMBU-A) (each parent separately) in depressive symptoms/anxiety and self esteem; assessing whether there are differences in the dimensions of the EMBU-A, between parents in the total sample and by gender; exploring associations between the study’s main variables (rearing styles, symptomatology and self esteem) and sociodemographic variables, also in the three samples; exploring differences between the four groups created (Father-Son, Father-Daughter, Mother-Son and Mother-Daughter) in the dimensions of the EMBU-A, combining Overprotection and Emotional Support(EMBU-A) and defining the authoritarian, authoritative, indulgent, and neglectful parental rearing styles. The aim is also to estimate the prevalence of these in our sample (by Father and Mother) and explore their associations to the symptomatology and self esteem (separately, per parent). Methodology. Our sample is composed of 284 teenagers (average age = 14,5; DP = 1,68; girls, n = 171, 60,2%). All participants filled in a protocol of questionnaires consisting of a set of socio demographic questions by Rosenberg Self- Esteem Scale (RSES), by DASS-21 and by Parental Rearing Style Questionnaire for use with Adolescents (EMBU-A/A). Outcomes. It is important to emphasize the fact that teenagers perceive their mother as having higher values in all the EMBU-A dimensions compared to their father. In the same way, though with different patterns of association according to gender, it is important to emphasize the association of higher levels of Emotional Support and lower levels of depressive/anxious symptomathology and stress and the association of Overprotection and Rejection and higher levels of those outcomes. A father’s lower level of education is associated to a lower Emotional Support while a mother’s higher level of education is associated to a greater Overprotection. A dyad composed of male parent and male teenager presents lower outcomes in all EMBU-A dimensions if compared to dyads composed of mother-son/daughter. The authoritative style is the most prevalent in our sample (in both parents) and the authoritarian style is the one associated to higher scores of psychopathology and lower levels of self esteem. Debate. In general, the outcomes closely follow the literature review and reveal the association of higher values in the Emotional Support dimension and lower levels of psychopathology and stress and also the association of the dimensions of Overprotection and Rejection and higher levels of those outcomes. Equally, the authoritarian rearing style is clearly associated to the worst outcomes in those same variables. Some implications are discussed as far as psychoeducational programmes and parental rearing are concerned.

This work has as its main purpose to investigate the contribution of supply chain management in order to obtain competitive advantage by companies from the textile industry and from Ceará footwear industry, focusing its analysis mainly in the interorganizational relations (dyadic). For this, the theoretical referential contemplates different explanatory streams of the competitive advantage, detaching the relational perception of the resources theory, as well as, the main presuppositions of the supply chain management which culminates with the development of an analysis sample that runs the empirical study; the one which considers an expanded purpose of the supply chain which includes the government and the abetment institutions as institutional environment representatives. Besides supply chain management consideration as a competitive advantage source, the work also tried to identify other possible competitive advantage sources for the companies of the investigated sectors. It represents a study of multiple interpretive cases, having four cases as a total; meaning two cases in each one of the sectors, which used as a primary data collecting instrument a semi-structured interview schedule. Different methods were used for the data analysis, the content analysis and the constant comparison methods, the analytical procedure originated from the grounded theory research strategy, which were applied the Atlas/ti software recourse. Considering the theoretical referential and the used analysis sample, four basic categories of the work were defined, including its respective proprieties and dimensions: (1) characteristics concerning to the relationship with the supplier; (2) the company relations with the government; (3) the company relations with the abetment institutions and; (4) obtaining sources of competitive advantage. In general, the applied research in the footwear sector revealed that in the relationships of the researched companies related to its suppliers, there is a predominance of the partnership system and the main presuppositions of the supply chain management are applied which contributes for the acquisition of the relational competitive advantage; while in the textile sector, only some of these presuppositions are applied, with little contribution for the relational competitive advantage. The main resource which was accessed by the companies in both sectors through its relationships with the government and the abetment institutions are the tax incentives which, for the footwear companies, contribute for the acquisition of the temporary competitive advantage in relation to the contestants who do not own productive installations in the Northeast region, it also conducts to a competitive parity situation in relation to the contestants who own productive installations in the Northeast region and to the external market contestants; while for the companies of the textile sector, the tax incentives run the companies to a competitive parity situation in relation to its contestants. Furthermore, the investigated companies from the two sectors possess acquisition sources of the competitive advantage which collimate with different explanatory streams (industrial analysis, resources theory, Austrian school and the dynamic capabilities theory), although there is a predominance of the product innovation as a competitive advantage source in both sectors, due to the bond of these with the fashion tendencies

Esta investigación tuvo como objetivo realizar una evaluación preliminar del potencial geo-térmico de la zona norte y noroccidental del Volcán Nevado del Ruiz (VNR), mediante la medición de la conductividad térmica y la capacidad calorífica de muestras de roca, e identificar los principales impactos ambientales asociados al aprovechamiento de los re-cursos geotérmicos en zonas volcánicas. El VNR es un estratovolcán activo, ubicado en el Parque Nacional Natural Los Nevadas, en los límites entre los departamentos de Caldas y Tolima. La explotación de los recursos geotérmicos en esta área podría suplir las necesi-dades energéticas locales, particularmente para la agricultura basada principalmente en el cultivo de café. La conductividad térmica y la capacidad calorífica fueron determinadas en 62 muestras de roca colectadas en la zona norte y noroccidental del VNR durante una salida de campo realizada en noviembre del 2014; la conductividad térmica fue medida utilizando una son-da de aguja, y la capacidad calorífica fue estimada de acuerdo con el tipo de roca. Estos datos, junto con el flujo de calor, se utilizaron para estimar la temperatura a profundidad y posteriormente calcular el potencial geotérmico a lo largo de un perfil geológico inferido trazado en el área del estudio. Los impactos ambientales fueron identificados a partir de una revisión bibliográfica que permitió seleccionar tres centrales geotérmicas en opera-ción ubicadas en zonas volcánicas, similar a la futura central geotérmica planeada en el área del VNR, para las cuales algunos impactos habían sido caracterizados.

Por serem diversas as situações clínicas em que existe impossibilidade de autoavaliação da dor pela criança, é relevante saber se avaliação da dor por parte dos pais/ acompanhante significativo e enfermeiros se aproxima do autorrelato da criança. A amostra contempla díades de 64 participantes: crianças com idades compreendidas entre os 5 e os 17 anos (inclusive), que se encontravam internadas ou recorreram aos Serviços da SANFIL, pais/ acompanhante significativo das crianças e enfermeiros responsáveis pelos cuidados de enfermagem às crianças. O objetivo consistiu na avaliaçãoda correlação entre a avaliação da intensidade da dor relatada pela criança, pais/ acompanhante significativo e enfermeiros. Metodologicamente, tratou-se de um estudo descritivo correlacional, transversal, em que a avaliação da dor foi realizada com as escalas EVA e FLACC. Para análise da correlação entre a avaliação da dor da criança, pais/ acompanhante significativo e enfermeiros, recorreu-se ao coeficiente de correlação de Spearman. Na concordância entre as crianças, pais/ acompanhante significativo e enfermeiros utilizou-se a correlação intra-classe (ICC, com intervalo de confiança a 95%). Verificou-se uma associaçãopositiva moderada, entre a avaliação da intensidade da dor das crianças, pais/ acompanhante significativo e enfermeiros, sendo que os valores mais elevados de correlação ocorreram entre as crianças e os pais/ acompanhante significativo, e os mais baixos entre as crianças e os enfermeiros. A concordância entre a avaliação da dor pelas crianças, pais/ acompanhante significativo e enfermeiros foi excelente. Quando comparadas entre pares de observadores, a melhor posição de concordância verificou-se entre as crianças e os pais/ acompanhante significativo e a pior posição de concordância entre as crianças e os enfermeiros. Concluiu-se que a avaliação da dor das crianças se associa com a dos pais e enfermeiros, no entanto são os pais/ acompanhante significativo quem mais se aproximam da sua avaliação. Estes dados alertam-nos para o papel que os pais podem desempenhar na avaliação da dor da criança, quando ensinados para tal.

O Capital psicológico positivo (CPP) são capacidades psicológicas que definem um estado de desenvolvimento psicológico positivo em que a pessoa se caracteriza por: a) apresentar uma elevada confiança para despender o esforço necessário para ser bem sucedida em tarefas desafiantes; b) fazer atribuições positivas acerca dos acontecimentos que vão suceder no presente e no futuro; c) manifestar perseverança em relação aos objectivos definidos, e, quando necessário mostrar-se capaz de redireccionar os meios para atingir os fins; d) revelar capacidade para recuperar de adversidades. As capacidades psicológicas positivas que melhor definem os critérios anteriormente definidos são: auto-confiança, optimismo, esperança e resiliência. Neste estudo foram recolhidos dados do nível Psycap de 100 vendedores e avaliações de CCO em cinco facetas (harmonia interpessoal, espírito de iniciativa, conscienciosidade, identificação com a organização e orientação para os clientes) e o Output individual numa dada tarefa, tendo-se obtido 100 díades. Explorou-se neste estudo a relação existente entre o PsyCap e dois tipos de desempenho (intra e extra papel) e a relação entre o desempenho contextual e de tarefa. Os resultados indicam que o PsyCap se relaciona com os dois tipos de desempenho, bem como a existência de uma relação entre desempenho contextual e tarefa. Considerações e implicações dos resultados são discutidas ao longo do trabalho.
