Determination of thresholds in marine molluscs as an alternative to the Environmental Quality Standards in marine water defined in the Water Framework Directive

The Water Framework Directive (WFD) establishes Environmental Quality Standards (EQS) in marine water for 34 priority substances. Among these substances, 25 are hydrophobic and bioaccumulable (2 metals and 23 organic compounds). For these 25 substances, monitoring in water matrix is not appropriate and an alternative matrix should be developed. Bivalve mollusks, particularly mussels (Mytilus edulis, Mytilus galloprovincialis), are used by Ifremer as a quantitative biological indicator since 1979 in France, to assess the marine water quality. This study has been carried out in order to determine thresholds in mussels at least as protective as EQS in marine water laid down by the WFD. Three steps are defined: - Provide an overview of knowledges about the relations between the concentrations of contaminants in the marine water and mussels through bioaccumulation factor (BAF) and bioconcentration factor (BCF). This allows to examine how a BCF or a BAF can be determined: BCF can be determined experimentally (according to US EPA or ASTM standards), or by Quantitative Activity-Structure Relationship models (QSAR): four equations can be used for mussels. BAF can be determined by field experiment; but none standards exists. It could be determined by using QSAR but this method is considered as invalid for mussels, or by using existing model: Dynamic Budget Model, but this is complex to use. - Collect concentrations data in marine water (Cwater) in bibliography for those 25 substances; and compare them with concentration in mussels (Cmussels) obtained through French monitoring network of chemicals contaminants (ROCCH) and biological integrator network RINBIO. According to available data, this leads to determine the BAF or the BCF (Cmussels /Cwater) with field data. - Compare BAF and BCF values (when available) obtained with various methods for these substances: BCF (stemming from the bibliography, using experimental process), BCF calculated by QSAR and BAF determined using field data. This study points out that experimental BCF data are available for 3 substances (Chlorpyrifos, HCH, Pentachlorobenzene). BCF by QSAR can be calculated for 20 substances. The use of field data allows to evaluate 4 BAF for organic compounds and 2 BAF for metals. Using these BAF or BCF value, thresholds in shellfish can be determined as an alternative to EQS in marine water.

O impacto das Bibliotecas Escolares na promoção dos Hábitos de Leitura

Dada a importância que é atribuída à leitura, entendida como ferramenta essencial para a plena inserção dos cidadãos na sociedade, a luta pela melhoria dos níveis de leitura e literacia da população portuguesa tornou-se um desígnio nacional bastante enfatizado nas últimas décadas. Vários estudos sobre hábitos de leitura efectuados na década de 80/90, quer a nível nacional quer internacional, vieram pôr a descoberto as fragilidades de Portugal e o seu atraso em relação aos restantes países da Europa. Os portugueses não revelavam as competências necessárias para ter sucesso na sociedade da informação. O sistema educativo tem um papel chave na mudança que é urgente operar, residindo os alicerces dessa mudança na promoção da leitura e da literacia. É neste contexto que surge a criação da Rede de Bibliotecas Escolares, lançada em 1996, como medida conjunta do Ministério da Educação e da Cultura, com vista a criar condições para que os portugueses pudessem alcançar níveis de leitura mais favoráveis e mais próximos dos restantes países europeus. A promoção da leitura passa a ser uma área de intervenção prioritária das bibliotecas escolares em Portugal. Face aos baixos níveis de literacia dos alunos portugueses, revelados pelo PISA 2000, o governo dá continuidade às suas políticas de promoção da leitura e da literacia. No ano de 2007 é apresentado o Plano Nacional de Leitura (PNL), fazendo-se o apelo à mobilização de todos como condição essencial para a sua eficácia - elevar os níveis de literacia dos portugueses. É importante dar nota que o PNL e as Bibliotecas Escolares estão fortemente conectados, funcionando estas como os “alicerces” que suportam o desenvolvimento dos projectos do PNL. Os resultados desta “parceria” e de todas as iniciativas com vista à promoção da leitura e da literacia têm-se revelado bastante profícuos, e a prová-lo estão os resultados do PISA 2009. Tendo os anos de 2000 e 2009 como domínio de referência a leitura, constatou-se que nesse período de tempo houve uma clara melhoria dos níveis de literacia dos portugueses. Não obstante uma ligeira descida verificada nos resultados do ano de 2012, a OCDE sublinhou as melhorias que o país obteve desde que começou a ser avaliado. No entanto, julgamos pertinente dar nota que, para além desta evolução se ter verificado não apenas em Portugal, há países que evoluíram de forma muito mais acelerada, encontrando-se numa posição mais favorável que Portugal (25º posição), no ranking dos países da OCDE. Com o estudo que aqui apresentamos, baseado na análise de um universo de 8 bibliotecas escolares do concelho de Felgueiras, pretendemos conhecer a realidade destas bibliotecas dentro do contexto nacional. Foi nosso objetivo verificar se cumprem o seu papel na promoção dos hábitos de leitura e da literacia, de que forma o fazem, e as dificuldades concretas com que se deparam. As conclusões apontam-nos para uma realidade que não difere muito da realidade das restantes bibliotecas do país, das quais temos conhecimento. Os professores bibliotecários cumprem o seu papel na promoção dos hábitos de leitura, deparando-se com a falta de apoio de meios humanos, aspecto que se tem agravado de forma preocupante nos últimos anos. A conjuntura atual de desinvestimento nos serviços públicos, não poderia deixar de se fazer sentir. Constatamos no entanto que, apesar das adversidades, as BEs não se reduzem a meros centros de recursos e a locais de lazer para quem as queira visitar. Têm um papel ativo, tomam incitativas diversas de promoção da leitura / literacia, nos moldes definidos pelo MABE, com estímulo à leitura autónoma. Procuram articular as suas acções com os docentes e, em simultâneo, vencer a relativa indiferença e desinteresse destes pela biblioteca, motivando-os para as suas actividades e procurando levá-los a ver na BE um parceiro ativo, capaz de os apoiar na concretização dos programas curriculares e na análise de resultados escolares dos alunos como base para delinear estratégias pedagógicas comuns. Por fim, constatamos que apesar de as BEs procurarem integrar nas suas atividades a comunidade exterior à escola, a adesão, sobretudo das famílias, tem sido débil: os encarregados de educação aderem relativamente bem ao papel de público passivo, mas não assumem o papel de interlocutores ativos, como se pretende. Estas conclusões, ousamos dizer, remetem-nos para a necessidade urgente de uma reflexão séria por parte do Estado Português, em relação à Educação e às suas prioridades.

Measuring passers-by engagement with AmPost: a printed interactive audio poster

This paper presents AmPost, a prototype of an interactive audio poster, which integrates ink-jet printed sonic and tactile elements along with textual and graphical information. This enables users to directly interact and engage with the poster. To achieve a seamless paper-based interactive poster that includes printed interactive elements, we implement a printed speaker and audio feedback system directly into the paper-based medium, which plays a short tune when someone walks by. Engaging passers-by with this new interface becomes a challenge as posters, in general, are non-interactive. This paper also presents an initial empirical evaluation of AmPost that captures and analyses the frequency and length of user engagement, and evaluates whether user engagement improves with the integration of interactive features, in comparison to the traditional non-interactive poster. This study facilitates in building the generic approach to measure engagement that applies to any kind of posters.

Reading nineteenth century schoolbooks online : user behavior in a digitized special collection

Special collections, because of the issues associated with conservation and use, a feature they share with archives, tend to be the most digitized areas in libraries. The Nineteenth Century Schoolbooks collection is a collection of 9000 rarely held nineteenth-century schoolbooks that were painstakingly collected over a lifetime of work by Prof. John A. Nietz, and donated to the Hillman Library at the University of Pittsburgh in 1958, which has since grown to 15,000. About 140 of these texts are completely digitized and showcased in a publicly accessible website through the University of Pittsburgh’s Library, along with a searchable bibliography of the entire collection, which expanded the awareness of this collection and its user base to beyond the academic community. The URL for the website is http://digital.library.pitt.edu/nietz/. The collection is a rich resource for researchers studying the intellectual, educational, and textbook publishing history of the United States. In this study, we examined several existing records collected by the Digital Research Library at the University of Pittsburgh in order to determine the identity and searching behaviors of the users of this collection. Some of the records examined include: 1) The results of a 3-month long user survey, 2) User access statistics including search queries for a period of one year, a year after the digitized collection became publicly available in 2001, and 3) E-mail input received by the website over 4 years from 2000-2004. The results of the study demonstrate the differences in online retrieval strategies used by academic researchers and historians, archivists, avocationists, and the general public, and the importance of facilitating the discovery of digitized special collections through the use of electronic finding aids and an interactive interface with detailed metadata.

A novel characterisation model for microvasulature changes following closed soft tissue trauma using micro-CT imaging

INTRODUCTION There is evidence that the reduction of blood perfusion caused by closed soft tissue trauma (CSTT) delays the healing of the affected soft tissues and bone [1]. We hypothesise that the characterisation of vascular morphology changes (VMC) following injury allows us to determine the effect of the injury on tissue perfusion and thereby the severity of the injury. This research therefore aims to assess the VMC following CSTT in a rat model using contrast-enhanced micro-CT imaging. METHODOLOGY A reproducible CSTT was created on the left leg of anaesthetized rats (male, 12 weeks) with an impact device. After euthanizing the animals at 6 and 24 hours following trauma, the vasculature was perfused with a contrast agent (Microfil, Flowtech, USA). Both hind-limbs were dissected and imaged using micro-CT for qualitative comparison of the vascular morphology and quantification of the total vascular volume (VV). In addition, biopsy samples were taken from the CSTT region and scanned to compare morphological parameters of the vasculature between the injured and control limbs. RESULTS AND DISCUSSION While the visual observation of the hindlimb scans showed consistent perfusion of the microvasculature with microfil, enabling the identification of all major blood vessels, no clear differences in the vascular architecture were observed between injured and control limbs. However, overall VV within the region of interest (ROI)was  measured to be higher for the injured limbs after 24h. Also, scans of biopsy samples demonstrated that vessel diameter and density were higher in the injured legs 24h after impact. CONCLUSION We believe these results will contribute to the development of objective diagnostic methods for CSTT based on changes to the microvascular morphology as well as aiding in the validation of future non-invasive clinical assessment modalities.

Online video in education : acquisition, value & ROI

The session explores the potential for “Patron Driven Acquisition” (PDA) as a model for the acquisition of online video. Today, PDA has become a standard model of acquisition in the eBook market, more effectively aligning spend with use and increased return on investment (ROI). PDA is an unexplored model for acquisition of video, for which library collection development is complicated by higher storage and delivery costs, labor overheads for content selection and acquisition, and a dynamic film industry in which media and the technology that supports it is changing daily. Queensland University of Technology (QUT) and La Trobe University in Australia launched a research project in collaboration with Kanopy to explore the opportunity for PDA of video. The study relied on three data sources: (1) national surveys to compare the video purchasing and use practices of colleges, (2) on-campus pilot projects of PDA models to assess user engagement and behavior, and (3) testing of various user applications and features to support the model. The study incorporates usage statistics and survey data and builds upon a peer-reviewed research paper presented at the VALA 2014 conference in Melbourne, Australia. This session will be conducted by the researchers and will graphically present the results from the study. It will map out a future for video PDA, and how libraries can more cost-effectively acquire and maximize the discoverability of online video. The presenters will also solicit input and welcome questions from audience members.

African Gamer: Whose Story Is It Anyway?

New Video Gamer: Africa Needs More Technology (CNN 12/12/2011) In December 2011 CNN news service online edition (Sutter, 2011) posted a short item about Cwi Nqane, a Khoisan man who entered Samsung’s Namibian World Cyber Games (WCG) heats held at the 2011 the annual Windhoek Show. Cwi Nqane won a place on the Namibian WCG team playing a smartphone game called Asphalt 6: Adrena-line (Gameloft, 2011). Cwi was presented with a ‘top of the line’ Samsung Galaxy tablet and subsequently sent to compete in Korea. Later, other news and game news websites re-reported the incident, which inspired a variety of enthusiastic comment about tech-nology and ‘new knowledge’. Then Kotaku news service picked up the item (Narcisse, 2011) and took a very different slant. Kotaku proposed that Samsung was exploiting Cwi and had assumed the role of a Techno-Tarzan: “striding into Nqane’s homeland and swinging him off into the wonders of the modern world where they can trot him out as a curiosity”. These two perspectives on the story of Cwi’s WCG entry expose two dominant views on Indigenous knowledges and technologies: ICTs as progress for in-digenous peoples and ICTs as disruptive and exploitative. Neither position, however, allows for the claiming of digital technology by indigenous communities, indeed both views position indigenous cultures as being outsiders.

Establishing a framework for transforming student engagement, success and retention in higher education institutions
