Interlibrary loan in primary access libraries: challenging the traditional view

Introduction: Primary access libraries serve as the foundation of the National Network of Libraries of Medicine (NN/LM) interlibrary loan (ILL) hierarchy, yet few published reports directly address the important role these libraries play in the ILL system. This may reflect the traditional view that small, primary access libraries are largely users of ILL, rather than important contributors to the effectiveness and efficiency of the national ILL system.

AHEC library services: from circuit rider to virtual librarian

The North Carolina Area Health Education Centers Library and Information Services (NC AHEC LIS) Network provides library outreach services to rural health care providers in all nine AHEC regions of North Carolina. Over the last twenty-five years, the AHEC and university-based librarians have collaborated to create a model program for support of community-based clinical education and information access for rural health care providers. Through several collaborative projects, they have supported Internet access for rural health clinics. The NC AHEC Digital Library—under development by NC AHEC, University of North Carolina at Chapel Hill, Duke University, East Carolina University, and Wake Forest University—will further extend access to electronic biomedical information and resources to health professionals in a statewide digital library.

Library outreach: addressing Utah's “Digital Divide”

A “Digital Divide” in information and technological literacy exists in Utah between small hospitals and clinics in rural areas and the larger health care institutions in the major urban area of the state. The goals of the outreach program of the Spencer S. Eccles Health Sciences Library at the University of Utah address solutions to this disparity in partnership with the National Network of Libraries of Medicine—Midcontinental Region, the Utah Department of Health, and the Utah Area Health Education Centers. In a circuit-rider approach, an outreach librarian offers classes and demonstrations throughout the state that teach information-access skills to health professionals. Provision of traditional library services to unaffiliated health professionals is integrated into the library's daily workload as a component of the outreach program. The paper describes the history, methodology, administration, funding, impact, and results of the program.

A melanoma-specific VH antibody cloned from a fusion phage library of a vaccinated melanoma patient.

The human antimelanoma antibody V86 was cloned from a single-chain Fv molecule (scFv) fusion phage library displaying the heavy chain variable domain (VH) and light chain variable domain (VL.) repertoire of a melanoma patient immunized with genetically-modified autologous tumor cells. Previous ELISA tests for binding of the V86 fusion phage to a panel of human metastatic melanoma and carcinoma cell lines and primary cultures of normal melanocytes, endothelial, and fibroblast cells showed that measurable binding occurred only to the melanoma cells. In this communication, the strict specificity of V86 for melanoma cells was confirmed by immunohistochemical staining tests with cultured cells and frozen tissue sections. The V86 fusion phage stained melanoma cell lines but did not stain carcinoma cell lines or cultured normal cells; V86 also stained specifically the melanoma cells in sections of metastatic tissue but did not stain any of the cells in sections from normal skin, lung, and kidney or from metastatic colon and ovarian carcinomas and a benign nevus. An unexpected finding is that V86 contains a complete VH domain but only a short segment of a VL, domain, which terminates before the CDR1 region. This VL deletion resulted from the occurrence in the VL cDNA of a restriction site, which was cleaved during construction of the scFv library. Thus V86 is essentially a VH antibody. The effect of adding a VI. domain to V86 was examined by constructing scFv fusion phage libraries in which V86 was coupled to Vlambda or Vkappa domains from the original scFv library of the melanoma patient and then panning the libraries against melanoma cells to enrich for the highest affinity antibody clones. None of the V86-Vlambda clones showed significant binding to melanoma cells in ELISA tests; although binding occurred with most of the V86-Vkappa clones, it was generally weaker than the binding of V86. These results indicate that most of the VL domains in the original scFv library reduce or eliminate the affinity of V86 for melanoma cells. Accordingly, VH libraries could provide access to anti-tumor antibodies that might not be detected in scFv or Fab libraries because of the incompatibility of most randomly paired VH and VL, domains.

Prospect for development of Open Access in Argentina

This perspective article presents an overview of the Open Access movement in Argentina, from a global and regional (Latin American) context. The article describes the evolution and current state of initiatives by examining two principal approaches to Open Access in Argentina: golden and green roads. The article will then turn its attention to: the support that Open Access receives from governmental sources; collaboration with international projects; and the perspective of Argentine authors regarding Open Access and self-archiving. It concludes with a reflection on the outlook, the main barriers and opportunities for Open Access in Argentina

L’abilità di perspective taking : un training per bambini in età prescolare in differenti contesti

Elemento centrale della presente tesi dottorale è il costrutto di perspective taking, definibile come l’abilità, emergente nei bambini intorno a 4-5 anni, di assumere la prospettiva altrui secondo tre differenti dimensioni: emotiva, cognitiva e percettiva (Bonino, Lo Coco, Tani, 1998; Moll e Meltzoff, 2011). Dalla letteratura emerge come il perspective taking, in quanto abilità di comprensione sociale, rivesta un ruolo adattivo e sia fondamentale per lo sviluppo, non solo intellettivo, ma anche per la formazione di adeguate capacità relazionali e sociali (Jenkins e Astington, 2000; Weil et al., 2011). Sulla base di tali considerazioni, alcuni ricercatori si sono interrogati sulla possibilità di insegnare questa abilità, elaborando specifiche e differenti procedure di intervento finalizzate ad incrementare l’abilità di perspective taking sia in bambini a sviluppo normativo (Cigala e Mori, 2015), sia in gruppi di bambini a sviluppo atipico (Fisher e Happé, 2005; Heagle e Rehfeldt, 2006; Paynter e Peterson, 2012). A partire da una prospettiva teorica socio-costruzionista, secondo cui l’acquisizione del perspective taking si configura come un’impresa di co-costruzione continua, all’interno di interazioni quotidiane con figure significative per il bambino, si è deciso di analizzare il perspective taking non solo in relazione a variabili individuali (genere, età del bambino, regolazione emotiva, abilità sociali) ma anche e soprattutto a variabili contestuali quali le caratteristiche del contesto familiare (caratteristiche disposizionali e stili genitoriali di socializzazione emotiva, presenza di fratelli). Sono stati in particolare indagati un contesto familiare normativo ed uno caratterizzato da maltrattamento psicologico, contrassegnato dalla reiterazione di comportamenti inadeguati (critiche svalutanti, denigrazione, umiliazione, minacce verbali, indifferenza) nei confronti del minore, che convogliano sul bambino l’idea di non essere amato e di avere poco valore. Con i termini “a sviluppo tipico” si intendono i bambini per i quali non sussista una diagnosi clinica e con quelli di “famiglie normative” ci si riferisce a nuclei per i quali non ci siano state segnalazioni da parte dei Servizi Educativi e Sociali di riferimento, indipendentemente dalle caratteristiche della composizione del nucleo familiare (nucleare, estesa, multipla, ricostituita o ricomposta). Tale studio rientra in un ampio progetto di ricerca e formazione che ha coinvolto più di 250 prescolari frequentanti 8 scuole dell’infanzia e 15 comunità terapeutiche e di accoglienza mamma-bambino, situate in differenti province del Nord Italia. Il gruppo dei partecipanti alla ricerca si è composto di 256 bambini in età prescolare, compresa quindi tra 3 e 5 anni (M=54,39; DS=5,705): 128 maschi (M=54,08; DS=5,551) e 128 femmine (M=54,70; DS=5,860). In particolare, 213 bambini appartenevano a famiglie normative e 43 a nuclei familiari caratterizzati dalla presenza di maltrattamento psicologico. Oltre ai bambini, la ricerca ha previsto il coinvolgimento di 155 coppie di genitori, 43 madri ospitate in comunità, 18 insegnanti e 30 operatori. Obiettivo centrale è stato l’indagine della possibilità di poter promuovere il perspective taking in bambini di età prescolare a sviluppo tipico appartenenti a due differenti tipologie di contesto familiare (normativo e psicologicamente maltrattante), attraverso l’applicazione di uno specifico percorso di training di natura “ecologica” all’interno della scuola dell’infanzia e della comunità, assimilabile a quelli di tipo evidence based. In particolare è stata prevista una procedura quasi sperimentale di tipo pre-test, training, post-test e follow-up. Dopo una preliminare valutazione dello sviluppo del perspective taking nelle sue tre componenti, in bambini appartenenti ad entrambi i contesti, si è voluto verificare l’esistenza di eventuali relazioni tra questa abilità ed alcune capacità socio-emotive dei bambini, con particolare riferimento alla disposizione prosociale, rilevate nel contesto scolastico attraverso differenti metodologie (osservazioni dirette non partecipanti, questionari self report compilati dalle insegnanti). Inoltre, data l’importanza del contesto familiare per lo sviluppo di tale abilità, la ricerca ha avuto lo scopo di verificare l’esistenza di eventuali relazioni tra le abilità di perspective taking mostrate dai bambini e gli stili di socializzazione emotiva delle figure familiari, caratteristiche di entrambi i contesti (maltrattante e non maltrattante). È stato inoltre previsto uno studio di confronto tra i due campioni rispetto alle dimensioni indagate. I risultati ottenuti sono stati particolarmente interessanti. Innanzitutto, le esperienze di training hanno determinato, in entrambi i contesti, miglioramenti nell’abilità dei prescolari di mettersi nei panni altrui. Tale training ha inoltre dimostrato effetti positivi sulla competenza sociale dei bambini, che, a seguito del percorso, hanno manifestato un incremento dei comportamenti prosociali ed una diminuzione di quelli aggressivi. Per lo studio in contesto normativo, è stato inoltre dimostrato un mantenimento delle abilità acquisite a seguito del training attraverso un follow-up a distanza di 4 mesi dal termine dell’intervento. Il positivo esito di tale percorso sembra quindi rappresentare un’importante risorsa per i prescolari, soprattutto in caso di situazioni in cui l’abilità di perspective taking risulti deficitaria. Il confronto dei due gruppi a seguito del training ha evidenziato come non siano emerse differenze significative, rispetto al perspective taking, ad eccezione della dimensione emotiva, in cui le prestazioni dei prescolari maltrattati sono risultate inferiori, come già evidenziato prima del training. Tali risultati non giungono però inaspettati, poiché, sebbene il percorso abbia agito significativamente sull’abilità di comprensione delle emozioni altrui di questi bambini, non si configura come sufficiente a ristrutturare così profondamente le problematiche presentate. Interessanti sono stati altresì i risultati ottenuti dall’analisi degli stili di socializzazione emotiva, dei genitori (madri e padri) dei prescolari non maltrattati e delle mamme dei bambini residenti in comunità. In particolare è emerso come, stili accettanti e di tipo coaching nei confronti delle emozioni negative dei bambini, siano positivamente correlati con il perspective taking dei figli, e come all’opposto, stili rifiutanti rispetto alle espressioni emotive negative dei propri bambini, mostrino correlazioni negative con le abilità di perspective taking dei figli. Oltre ad interessi di ordine teorico e metodologico, è possibile quindi affermare come, il presente lavoro di tesi, sia stato guidato da fini applicativi, affinché la ricerca scientifica possa tradursi in pratiche educative quotidiane da applicare ai contesti di vita significativi per i bambini.

Desenvolvimento de um modelo baseado em agentes para investigar a conformação e evolução de padrões populacionais de atividade física no lazer em adultos

Introdução: Grande parte das ações para promover a atividade física no lazer em populações tem apresentado tamanhos de efeito pequenos ou inexistentes, ou resultados inconsistentes. Abordar o problema a partir da perspectiva sistêmica pode ser uma das formas de superar esse descompasso. Objetivo: Desenvolver um modelo baseado em agentes para investigar a conformação e evolução de padrões populacionais de atividade física no lazer em adultos a partir da interação entre atributos psicológicos dos indivíduos e atributos dos ambientes físico construído e social em que vivem. Métodos: O processo de modelagem foi composto por três etapas: elaboração de um mapa conceitual, com base em revisão da literatura e consulta com especialistas; criação e verificação do algoritmo do modelo; e parametrização e análise de consistência e sensibilidade. Os resultados da revisão da literatura foram consolidados e relatados de acordo com os domínios da busca (aspectos psicológicos, ambiente social e ambiente físico construído). Os resultados quantitativos da consulta com os especialistas foram descritos por meio de frequências e o conteúdo das respostas questões abertas foi analisado e compilado pelo autor desta tese. O algoritmo do modelo foi criado no software NetLogo, versão 5.2.1., seguindo-se um protocolo de verificação para garantir que o algoritmo fosse implementado acuradamente. Nas análises de consistência e sensibilidade, utilizaram-se o Teste A de Vargha-Delaney, coeficiente de correlação de postos parcial, boxplots e gráficos de linha e de dispersão. Resultados: Definiram-se como elementos do mapa conceitual a intenção da pessoa, o comportamento de pessoas próximas e da comunidade, e a percepção da qualidade, do acesso e das atividades disponíveis nos locais em que atividade física no lazer pode ser praticada. O modelo representa uma comunidade hipotética contendo dois tipos de agentes: pessoas e locais em que atividade física no lazer pode ser praticada. As pessoas interagem entre si e com o ambiente construído, gerando tendências temporais populacionais de prática de atividade física no lazer e de intenção. As análises de sensibilidade indicaram que as tendências temporais de atividade física no lazer e de intenção são altamente sensíveis à influência do comportamento atual da pessoa sobre a sua intenção futura, ao tamanho do raio de percepção da pessoa e à proporção de locais em que a atividade física no lazer pode ser praticada. Considerações finais: O mapa conceitual e o modelo baseado em agentes se mostraram adequados para investigar a conformação e evolução de padrões populacionais de atividade física no lazer em adultos. A influência do comportamento da pessoa sobre a sua intenção, o tamanho do raio de percepção da pessoa e a proporção de locais em que a atividade física no lazer pode ser praticada são importantes determinantes da conformação e evolução dos padrões populacionais de atividade física no lazer entre adultos no modelo.

Arthroscopic stabilisation of an acute acromioclavicular dislocation grade III in a patient with ectopic insertion of the pectoralis minor: technical considerations

The different approaches used in arthroscopic stabilisation of the acromioclavicular joint are well known. However, and despite a great incidence of ectopic pectoralis minor insertion, an alternative choice for the use of arthroscopic portal has not being sufficiently described. Here, we describe a case of acute acromioclavicular dislocation grade III. The arthroscopic stabilisation was achieved using the TightRope (Arthrex, Naples, USA) implant. Through this technique, the approach to the articular portion of the coracoid process can be made intra-articularly or from the subacromial space. We accessed intra-articularly, by opening the rotator interval to reach the coracoid process from the joint cavity. After opening the rotator interval, an ectopic insertion of the pectoralis minor was observed. The choice of approach of the coracoid process from the subacromial space would have complicated the intervention, making it necessary to sever the ectopic tendon to complete the technique, lengthening the surgical time and increasing the chance of complications. For this reason, the use of a standard posterior portal providing intra-articular arthroscopic access through the rotator interval is recommended since the aforementioned anatomical variation is not infrequent.

Digitizing the Historical Periodical Collection at the Al-Aqsa Mosque Library in East Jerusalem

The Arab Press in Palestine developed at the turn of the twentieth century and proliferated for several decades despite restrictions imposed under the Ottoman Empire and during the British Mandate Period (1917-1948). Hardcopies of the early newspapers and periodicals are rare and access to them at a few Palestinian municipal or private libraries is limited. The Al-Aqsa Mosque Library holds one of the largest collections of Palestinian historical newspapers and periodicals. The collection provides a unique and rich source of information about the history of Palestine in the first half of the twentieth century. Access to the collection is limited and brittle paper copies have been rapidly deteriorating. This paper provides an overview of the digitization project aimed at preserving the historical periodical collection located at the AlAqsa Mosque Library

Utilizing Building Usage Assessment: Determining Deployment of Student Workers in an Academic Library

Generating, collecting, and analyzing building usage statistics can greatly increase the ability of an access services unit to meet the changing dynamic of patron needs in an academic library. By analyzing three different data points, the Access Services Unit in Malpass Library at Western Illinois University was able to determine the most effective and efficient way to deploy the student workforce to meet the demonstrated needs of the patron population throughout the day. This article will examine those data points and how they were analyzed in order to improve the services provided by the Access Services Unit.

How Does the Denver Public Library System Respond to its Customer's Requests for Global Information?

The interaction between globally available information and public library users is a changing one. Global information is readily available yet provider and user struggle to find efficiencies of time and resources. As a primary resource of global information the Denver Public Library (DPL) is approaching this challenge by providing changing technology to a changing user and by providing a customized approach to immigrant populations. DPL provides global information to library users through collections, programs and Internet. Internet and collections global information usage cannot be directly measured due to privacy restrictions. Only 12.5% of general user programs focus on global information. Four percent of budget serves the immigrant users. This is greater than national averages.

The Universality of Civil War Definitions: A Study of How Regional Considerations Impact Civil War in Somalia, Colombia, and Angola

Civil war is a socially intimate phenomenon. The viability of the conflict hinges on recruitment for the cause, military strategy, community support, and a variety of other conditional factors. Despite this dependence on local society, many researchers approach civil war from a global perspective, attempting to discover universal truths about this kind of conflict. This capstone project focuses on restricting the operating parameters of civil war research projects to the span of a single continent, hoping to achieve deeper insight by focusing the research using a more culturally sensitive set of parameters. By using cultural data to guide civil war research, conflict indicators can tailor conflict prevention to escalating violent scenarios.

Experiences Using an Open Source Sofware Library to Teach Computer Vision Subjects

Machine vision is an important subject in computer science and engineering degrees. For laboratory experimentation, it is desirable to have a complete and easy-to-use tool. In this work we present a Java library, oriented to teaching computer vision. We have designed and built the library from the scratch with enfasis on readability and understanding rather than on efficiency. However, the library can also be used for research purposes. JavaVis is an open source Java library, oriented to the teaching of Computer Vision. It consists of a framework with several features that meet its demands. It has been designed to be easy to use: the user does not have to deal with internal structures or graphical interface, and should the student need to add a new algorithm it can be done simply enough. Once we sketch the library, we focus on the experience the student gets using this library in several computer vision courses. Our main goal is to find out whether the students understand what they are doing, that is, find out how much the library helps the student in grasping the basic concepts of computer vision. In the last four years we have conducted surveys to assess how much the students have improved their skills by using this library.

Association Patterns in Saproxylic Insect Networks in Three Iberian Mediterranean Woodlands and Their Resistance to Microhabitat Loss

The assessment of the relationship between species diversity, species interactions and environmental characteristics is indispensable for understanding network architecture and ecological distribution in complex networks. Saproxylic insect communities inhabiting tree hollow microhabitats within Mediterranean woodlands are highly dependent on woodland configuration and on microhabitat supply they harbor, so can be studied under the network analysis perspective. We assessed the differences in interacting patterns according to woodland site, and analysed the importance of functional species in modelling network architecture. We then evaluated their implications for saproxylic assemblages’ persistence, through simulations of three possible scenarios of loss of tree hollow microhabitat. Tree hollow-saproxylic insect networks per woodland site presented a significant nested pattern. Those woodlands with higher complexity of tree individuals and tree hollow microhabitats also housed higher species/interactions diversity and complexity of saproxylic networks, and exhibited a higher degree of nestedness, suggesting that a higher woodland complexity positively influences saproxylic diversity and interaction complexity, thus determining higher degree of nestedness. Moreover, the number of insects acting as key interconnectors (nodes falling into the core region, using core/periphery tests) was similar among woodland sites, but the species identity varied on each. Such differences in insect core composition among woodland sites suggest the functional role they depict at woodland scale. Tree hollows acting as core corresponded with large tree hollows near the ground and simultaneously housing various breeding microsites, whereas core insects were species mediating relevant ecological interactions within saproxylic communities, e.g. predation, competitive or facilitation interactions. Differences in network patterns and tree hollow characteristics among woodland sites clearly defined different sensitivity to microhabitat loss, and higher saproxylic diversity and woodland complexity showed positive relation with robustness. These results highlight that woodland complexity goes hand in hand with biotic and ecological complexity of saproxylic networks, and together exhibited positive effects on network robustness.
