Portal GeoVariscoPT, inovação, partilha e discussão no estudo do Varisco Português

GeoVariscoPT é um portal de utilização aberta concebido para permitir a discussão em torno de afloramentos que, pelas suas características, são chave para a compreensão da evolução prémesozóica de Portugal. Para cada afloramento, existe disponível para consulta uma série de dados de índole diversa (e.g. litoestratigráfica, estrutural ou geoquímica), podendo os utilizadores adicionarem em tempo real e sem qualquer controlo, os seus comentários sobre a interpretação dos afloramentos. Embora se trate de um portal concebido essencialmente para investigação pelas suas características pode igualmente ser utilizado em contexto pedagógico.

Formation of seep carbonates along the makran convergent margin, northern Arabian sea and a molecular and isotopic approach to constrain the carbon isotopic composition of parent methane

Authigenic carbonate deposits have been sampled with the remotely operated vehicle ‘MARUM-QUEST 4000 m’ from five methane seeps between 731 and 1823 m water depth along the convergent Makran continental margin, offshore Pakistan (northern Arabian Sea). Two seeps on the upper slope are located within the oxygen minimum zone (OMZ; ca. 100 to 1100 m water depth), the other sites are situated in oxygenated water below the OMZ (below 1100 m water depth). The carbonate deposits vary with regard to their spatial extent, sedimentary fabrics, and associated seep fauna: Within the OMZ, carbonates are spatially restricted and associated with microbial mats, whereas in the oxygenated zone below the OMZ extensive carbonate crusts are exposed on the seafloor with abundant metazoans (bathymodiolin mussels, tube worms, galatheid crabs). Aragonite and Mg-calcite are the dominant carbonate minerals, forming common early diagenetic microcrystalline cement and clotted to radial-fibrous cement. The δ18Ocarbonate values range from 1.3 to 4.2‰ V-PDB, indicating carbonate precipitation at ambient bottom-water temperature in shallow sediment depth. Extremely low δ13Ccarbonate values (as low − 54.6‰ V-PDB) point to anaerobic oxidation of methane (AOM) as trigger for carbonate precipitation, with biogenic methane as dominant carbon source. Prevalence of biogenic methane in the seepage gas is corroborated by δ13Cmethane values ranging from − 70.3 to − 66.7‰ V-PDB, and also by back-calculations considering δ13Cmethane values of carbonate and incorporated lipid biomarkers. These calculations (Δδ13Cmethane–carbonate, Δδ13CANME–methane, Δδ13CMOX–methane) prove to be useful to assess the carbon stable isotope composition of seeping methane if this has not been determined in the first place; such an approach represents a useful tool to reconstruct fluid composition of ancient seeps. AOM is also revealed by lipid biomarkers of anaerobic methane oxidizing archaea such as crocetane, pentamethylicosane (PMI), and sn2-hydroxyarchaeol strongly depleted in 13C (δ13C values as low as − 127‰ V-PDB). Biomarkers of sulphate-reducing bacteria are also abundant, showing slightly less negative δ13C values, but still significantly 13C-depleted (average values as low as − 101‰). Other bacterial biomarkers, such as bacteriohopanepolyols (BHPs), hopanols, and hopanoic acids are detected in most carbonates, but are particularly common in seep carbonates from the non-OMZ sites. The BHP patterns of these carbonates and their low δ13C values resemble patterns of aerobic methanotrophic bacteria. In the shallower OMZ sites, BHPs revealed much lower contents and varying compositions, most likely reflecting other sources than aerobic methanotrophic bacteria. 230Th/U carbonate ages indicate that AOM-induced carbonate precipitation at the deeper non-OMZ seeps occurred mainly during the late Pleistocene-Holocene transition, i.e. between 19 and 15 ka before present, when the global sea level was lower than today.

PORTAL DE PERIÓDICOS DA CAPES: UMA POLÍTICA PÚBLICA DE ACESSO À INFORMAÇÃO CIENTÍFICA E TECNOLÓGICA

Apresenta as políticas públicas de acesso à informação científica, destacando o insigne papel desempenhado pelo Portal de Periódicos da Coordenação Nacional de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). O estudo trata-se de uma pesquisa exploratória e bibliográfica. Aponta o Portal como redutor das desigualdades regionais relacionadas ao acesso à Informação em Ciência e Tecnologia, disponibilizando periódicos científicos veiculados aos avanços e discussões constituídas no contexto acadêmico nos diversos campos do conhecimento. Conclui que o Portal atua como importante instrumento no avanço da comunicação científica, subsidiando e promovendo o acesso à Informação em Ciência e Tecnologia em tempo real, disponibilizando aos pesquisadores grande fatia da produção científica internacional e nacional atualizada, propiciando o avanço da pós-graduação brasileira em nível stricto sensu. Contudo, por outro lado, deve existir um contínuo trabalho da CAPES de modernização da plataforma, mediante a aquisição de materiais informacionais atualizados com novos conteúdos e melhoria da interface.

Children's mental representations of attachment: associations with attachment security and parent-child narrative quality

The goal of this study was to examine the antecedents and correlates of children’s mental representations of attachment at 5 years (Attachment Story Completion Task, Bretherton, Ridgeway, & Cassidy, 1990; MacArthur Story Stem Battery, Bretherton, Oppenheim, Buchsbaum, Emde, & the MacArthur Narrative Group, 1990). Predictors included children’s attachment security with mothers and fathers assessed via the Attachment Q-Set (AQS, Waters, 1987) at 3 years, and parent-child narrative quality regarding positive and negative events at 5 years. Participants included 71 children and their mothers and fathers. Structural equation models (SEM) indicated that children’s attachment security exerted a significant indirect effect on children’s mental representations through parent-child narrative quality. Specifically, children’s attachment security with fathers was related to their mental representations via father-child reminiscing about positive events, and children’s attachment security with mothers was related to their mental representations via mother-child reminiscing about negative events. Results are discussed in terms of the development and implications of attachment relationships within the family context.

An exploration of parent ivolvement in Response to Intervention (RTI) in Title I schools

Research demonstrates that parental involvement positively impacts student achievement and enhances targeted instruction. Notably, however, little research currently exists on how schools involve parents in Response to Intervention (RTI), a framework for implementing targeted, tiered, research-based instruction. The purpose of this study was to interview selected parents, teachers, RTI specialists, and principals in three Title I elementary schools in one school district, plus one district-level administrator, in order to examine how elementary schools currently involve parents in RTI prereferral interventions, and to understand the factors that might facilitate or challenge such parent involvement. I employed a comparative case study qualitative design with each elementary school as the main unit of analysis. I conducted individual, in-depth interviews that lasted approximately 45-60 minutes with a total of 33 participants across the three school sites, including 11 parents, 12 teachers, and six RTI specialists, three principals, and one district-level administrator. I also analyzed documents related to RTI processes that are available through websites and participants. I used Strauss and Corbin’s (1998) three-step scheme for thematic/grounded theory analysis, and Atlas.ti as the electronic tool for management and analysis. Analyses of the data revealed that personnel across the sites largely agreed on how they explain RTI to parents and notify parents of student progress. Parents mostly disagreed with these accounts, stating instead that they learn about RTI and their child’s progress by approaching teachers or their own children with questions, or by examining report cards and student work that comes home. Personnel and parents cited various challenges for involving parents in RTI. However, they all also agreed that teachers are accessible and willing to reach out to parents, and that teachers already face considerable workloads. It appears that no district- or school-wide plan guides parent involvement practices in RTI at any of the three schools. Finally, I present a discussion of findings; implications for teachers, RTI implementation leaders, and Title school leaders; study limitations; and possibilities for future research.

Verhaltens- und fertigkeitenbasierte Frühinterventionen bei Kindern mit Autismus

Einleitung: Zu den autistischen Syndromen werden der frühkindliche Autismus (Kanner-Syndrom), das Asperger-Syndrom und atypische Autismusformen oder nicht-spezifizierte tiefgreifende Entwicklungsstörungen gezählt. Bei den autistischen Syndromen liegen Beeinträchtigungen (1) der Kommunikation und (2) der sozialen Interaktion vor. Weiterhin weisen (3) die Kinder in unterschiedlichem Maß stereotypes, repetitives Verhalten auf und haben bestimmte Sonderinteressen. Verhaltensbasierte Frühinterventionen bei Kindern mit Autismus basieren auf lerntheoretischen und verhaltenstherapeutischen Konzepten. Sie berücksichtigen die besonderen vorliegenden Beeinträchtigungen in der Wahrnehmung, der emotionalen Reaktionen, der sozialen Interaktionen sowie der Kommunikationsmuster. Die systematische Anwendung und Evaluation solcher Modelle in Deutschland ist aber bisher eher die Ausnahme. Fragestellungen: - Wie sind die gesundheitliche Effektivität und Sicherheit von verhaltens- oder fertigkeitenbasierten Frühinterventionen bei autistischen Syndromen untereinander und verglichen mit einer Standardbehandlung? - Gibt es Hinweise auf besondere Wirkfaktoren für die Effektivität? - Wie ist die Kosten-Effektivität? - Wie hoch sind die Kosten der verschiedenen Interventionen? - Lassen sich aus ethischen und rechtlichen Überlegungen Schlüsse für die Anwendung der betrachteten Interventionen bei Betroffenen mit autistischem Syndrom in der Praxis ziehen? Methoden: Basierend auf einer systematischen Literaturrecherche werden ab 2000 in deutscher oder englischer Sprache veröffentlichte kontrollierte Studien zu verhaltens- oder fertigkeitenbasierten Frühinterventionen bei Kindern mit Autismus im Alter von bis zu zwölf Jahren eingeschlossen und bewertet. Die Mindestzahl an Studienteilnehmern muss zehn pro Interventionsgruppe betragen. Ergebnisse: Insgesamt 15 Veröffentlichungen klinischer Primärstudien, acht systematische Reviews und eine ökonomische Veröffentlichung erfüllen die Einschlusskriterien. Die meisten Studien evaluieren intensive Frühinterventionen, die sich an das Modell von Lovaas (Early intensive behavioural treatment (EIBT), Applied behavioural analysis (ABA)) anlehnen. Einige Studien evaluieren andere Interventionen, die teilweise pragmatisch waren und teilweise einem bestimmten Modell folgen (spezifisches Elterntraining, Responsive education and prelinguistic milieu teaching (RPMT), Joint attention (JA) und symbolisches Spielen (SP), Picture exchange communication system (PECS)). Verhaltensanalytische Interventionen basierend auf dem Lovaas-Modell können weiterhin als die am besten empirisch abgesicherten Frühinterventionen angesehen werden. Vorschulkinder mit Autismus können durch verhaltensbasierte Interventionen mit einer Mindestintensität von 20 Stunden pro Woche Verbesserungen in kognitiven und funktionalen Bereichen (expressive Sprache, Sprachverständnis und Kommunikation) erreichen. Es bleibt jedoch unklar, welche Mindestintensität notwendig ist, und welche Wirkkomponenten für die Ergebnisse verantwortlich sind. Für andere umfassende Frühinterventionen bei Kindern mit Autismus liegt keine hochwertige Evidenz vor. Die für den ökonomischen Teilbereich identifizierte und einbezogene Publikation ist methodisch und thematisch nicht dazu geeignet, die Fragen nach der Kosten-Effektivität oder den Kostenwirkungen von Frühinterventionen beim Autismus auch nur ansatzweise zu beantworten. Publikationen zu rechtlichen, ethischen oder sozialen Aspekten werden nicht identifiziert. Die finanzielle Lage der Betroffenen und der Familien wird durch das Pflege-Weiterentwicklungsgesetz (Pf-WG) verbessert. Weitere rechtliche Belange betreffen die Betreuung und die Deliktfähigkeit der Menschen mit Autismus. Auch die gleichheitliche Betreuung und Versorgung sind insbesondere vor dem Hintergrund der Pflege im häuslichen Umfeld eine wichtige Frage. Diskussion: Es gibt nur wenige methodisch angemessene Studien zur Beurteilung der Wirksamkeit von Frühinterventionen bei Kindern mit Autismus. Die meisten Studien sind vergleichsweise kurz und haben teilsweise kein verblindetes Ergebnis-Rating. Der Mangel an hochwertigen vergleichenden Studien lässt keine solide Antwort auf die Frage zu, welche Frühintervention bei welchen Kindern mit Autismus am wirksamsten ist. Programme nach dem Lovaas-Modell scheinen am wirkungsvollsten zu sein. Dies gilt vor allem, wenn sie klinikbasiert durchgeführt werden. Zu einzelnen Wirkfaktoren von Frühinterventionen nach dem ABA-Modell konnte allerdings keine solide Evidenz gefunden werden. Es zeigte sich, dass ein Elterntraining hinsichtlich der Verbesserung der Kommunikation besser ist als eine Routinebehandlung, in der eine Mischung von Theapieelementen angewendet wird. Sowohl für die klinischen als auch die gesundheitsökonomischen Studien besteht das Problem unzureichender Verallgemeinerbarkeit der Studienergebnisse in den deutschen Versorgungskontext. Die ökonomischen Studien sind methodisch und thematisch nicht dazu geeignet die aufgeworfenen Fragestellungen zu beantworten. Schlussfolgerung: Basierend auf der derzeitigen Studienlage liegt für keine der untersuchten verhaltensbasierten Frühinterventionen bei Kindern mit Autismus ausreichende Evidenz vor. Die in diesem Bericht ausgewerteten Studien und Reviews legen nahe, dass Vorschulkinder mit Autismus durch verhaltensbasierte Interventionen mit einer Mindestintensität von 20 Stunden pro Woche Verbesserungen in kognitiven und funktionalen Bereichen erreichen können. Es gibt bisher keine Hinweise, dass bei einem substantiellen Anteil der Kinder eine vollständige Normalisierung der Entwicklung erreicht werden kann. Die meiste Evidenz liegt für die ABA vor. Ein Minimum an erforderlicher oder sinnvoller Behandlungsintensität kann jedoch nicht angegeben werden. Eine professionelle Umsetzung eines verhaltensbasierten Frühinterventionsprogrammes in engem und ausführlichem Kontakt mit den Kindern und unter Einbeziehung der Eltern erscheint sinnvoll. Zur Kosten-Effektivität von intensiven Frühinterventionen bei Kindern mit Autismus können keine validen Angaben gemacht werden. Effektive Frühinterventionen könnten jedoch die Gesamtkosten des Autismus langfristig reduzieren, indem die anfallenden hohen Aufwendungen durch eine spätere bessere soziale Anpassung überkompensiert werden.

Parents’ experiences during the transition from childhood to adolescence with Type 1 Diabetes: Parent-child relationships and support received during this time and clinical research portfolio

Background: Type 1 Diabetes (T1D) management often worsens as children become adolescents. This can be a difficult time for parents as they hand over responsibility of diabetes management to their adolescent. Objectives: To look at the experiences of parents with a child with T1D as they move to adolescence and take more responsibility for their diabetes management. To find out about parents’ experience of support during this transition. Subjects: Three parents of adolescents with T1D. Participants were recruited from the NHS Highland Paediatric Diabetes Service. Methods: Participants took part in a one-to-one semi-structured interview with a researcher. Interpretative Phenomenological Analysis was used to analyse the interviews and find common themes across the interviews. Results: Participants experienced worry throughout their child’s transition to adolescence. They found it difficult to let their child take responsibility for their diabetes but acknowledged that their involvement caused tensions with their adolescent. Participants’ experience was that there were a number of practical adjustments to be made with a diagnosis of T1D and educating the network around their child was important. The participants reported that the diagnosis of T1D had an impact on the whole family and not just the child with the diagnosis. The parents felt well supported medically but said that the amount of time before their first clinic appointment felt too long. All participants had concerns about their adolescent moving to the adult diabetic service. Conclusions: Participants experienced worry relating to aspects of their adolescents T1D that they could not control, but were aware of the tensions caused by trying to keep elements of control. Areas of future research were identified.

The Impact of Expropriations on the Stock Prices of the Parent Companies: Sell on the rumor, buy on the news?

We measure the impact of warnings of expropriation and of forced divestments of pri- vate property on the stock prices of the parent company. We use a unique database of 116 events in 12 countries from 2005 to 2013. Our results show signi cant negative effects on the stock prices of different kinds of warnings; the largest effect is when the warning takes the form of a transitory permit revocation. In the case of forced divestments, we nd a signi cant negative impact when there is a permanent revocation of a permit. However, nationalizations seem to generate a positive market reaction.

Non-communicable diseases among children in Ghana: health and social concerns of parent/caregivers.

Background: Globally, there is a progressive rise in the burden of non-communicable diseases (NCDs). This paper examined the health and social concerns of parents/caregivers on in-patient care for children with NCDs in Ghana. Methods: This was a cross-sectional study in three large health facilities in Ghana (the largest in the South, the largest in the North and the largest in the Eastern part of Ghana. Data was collected with a structured questionnaire among 225 caregivers (≥18 years) of 149 children with NCDs in health facilities in the three regions. Data was analyzed with simple descriptive statistics. Results: Most caregivers 169(75.0%) were women, relatively young (median age 35years), mostly married and resided in urban areas. Sickle cell disease was the commonest NCD among the children. All 169(75.0%) caregivers believed children suffer NCDs because of sins of parents/ancestors, 29(12.9%) believed herbalists/spiritualists have insights into treating NCDs and 73(32.6%) have previously used herbs/traditional medicine for child's illness. NCD in children was a burden and caused financial difficulties for families. Most caregivers (>96.0%) indicated NCDs in children should be included in national health insurance benefits package and a comprehensive national NCD policy is needed. Conclusion: Absence of national NCD policy for children is a major challenge. The burden of care rests mainly on the parents/ caregivers. A national strategic intervention on the importance of awareness generation on the causes, risk factors, prevention and treatment of NCDs for families and communities is essential. Government support through national health and social policy initiatives are essential.

Child-to-parent violence: the role of exposure to violence and its relationship to social-cognitive processing

Research suggests that child-to-parent violence (CPV) is related to a previous history of violence within the family setting. The current study was aimed to explore the exposure to violence in different settings (school, community, home, and TV) and its relationship to some variables of the social-cognitive processing (hostile social perception, impulsivity, ability to anticipate the consequences of social behaviors and to select the appropriate means to achieve the goals of social behaviors) in a group of juveniles who assaulted their parents. It is also examined how they differ from other young offenders and non-offender adolescents. The sample included 90 adolescents from Jaén (Spain). Thirty of them were juveniles who had been reported by their parents for being violent towards them and 30 were juveniles who had committed other types of offences. The third group was made up of 30 adolescents without any criminal charge. Adolescents answered measures of exposure to violence, perception of criticism/rejection from parents, hostile social perception, and social problem- solving skills. Results revealed that juveniles who abused their parents reported higher levels of exposure to violence at home when comparing to the other groups. In addition, exposure to violence at home was significantly correlated to the hostile social perception of adolescents in CPV cases. Implications for prevention and treatment are discussed

The Spanish online program "Educar en Positivo" ("The Positive Parent"): whom does it benefit the most?

This study evaluated the Spanish online program 'Educar en Positivo' ("The Positive Parent") (http://educarenpositivo.es). Eighty-five users were surveyed to examine changes in views of online parenting support and satisfaction with the module completed, as a function of their sociodemographic profile, their level of experience with the Internet, and their general and educational use of Internet resources. Results showed that parents changed their views of online support, the benefits thereof, and their parenting skills. Participants reported high satisfaction with the program's usability, the module content, and their perception of parental self-efficacy. These findings are moderated by level of Internet experience and educational use of web-based resources, suggesting that improving parents' digital literacy and promoting Internet use may be an effective avenue for improving access to prevention resources. In sum, this program offers a space for Spanish-speaking parents to learn and exchange experiences, thereby filling a gap in ensuring the promotion of positive parenting in this large community of potential users.
