Faculty and Student Perspectives Toward Open Courseware, and Open Access Publishing: Some Comparisons Between European and North American Populations

Instructor and student beliefs, attitudes and intentions toward contributing to local open courseware (OCW) sites have been investigated through campus-wide surveys at Universidad Politecnica de Valencia and the University of Michigan. In addition, at the University of Michigan, faculty have been queried about their participation in open access (OA) publishing. We compare the instructor and student data concerning OCW between the two institutions, and introduce the investigation of open access publishing in relation to open courseware publishing.

El Turisme de memòria a Catalunya: realitat i perspectives d'un model incipient

Catalunya disposa a l’actualitat de nombrosos equipaments culturals destinats a la difusió memorial mitjançant la pràctica turística creant-se, tanmateix, les primeres estructures en xarxa per tal de fer que aquests espais disposin d’un relat conjunt, element indispensable en el qual recolzar-se a l’hora d’emprendre qualsevol estratègia de difusió. El model català, però, pot dir-se que està en fase embrionària, i des d’aquest moment en endavant ens correspon als professionals i acadèmics treballar de cara a la seva consolidació. Aquest estudi posa les bases per a la investigació en clau turística sobre els Espais de Memòria

Nuevas perspectivas de la orientación profesional para responder a los cambios y necesidades de la sociedad de hoy = New Perspectives in Career Counseling which Respond to the Changes and Needs of Society Today

In this paper a brief outline of the origin and development of vocational guidance and career development during the 20thcentury is presented We elaborate a summary of the changes society has suffered during the last decades, and which affect career counselling either directly or indirectly, and which imply a need for modifications in the current approach to career counselling. Subsequently, we propose new perspectives that will be needed to face these changes, and which have been suggested by different authors. Also some competencies needed by career counselors while acting at different levels of intervention are suggested

Importance of the embedding environment on the strain within small rings in siliceous materials

The effect of the local environment on the energetic strain within small (SiO)N rings (with N=2,3) in silica materials is investigated via periodic model systems employing density functional calculations. Through comparison of the energies of various nonterminated systems containing small rings in strained and relatively unstrained environments, with alpha quartz, we demonstrate how small ring strain is affected by the nature of the embedding environment. We compare our findings with numerous previously reported calculations, often predicting significantly different small-ring strain energies, leading to a critical assessment of methods of calculating accurate localized ring energies. The results have relevance for estimates of the strain-induced response (e.g., chemical, photo, and radio) of small silica rings, and the propensity for them to form in bulk glasses, thin films, and nanoclusters.

Detecting Detection: International Perspectives on the Uses of a Plot

One of the problems with books which are relatively general in nature is that many of the individual contributions tend to be so narrow and specialised that only the author has any knowledge of (or interest in) the issues under discussion. At first sight this appears to be the case with Detecting Detection. Fortunately, however, first impressions are deceiving. Although the essays in the volume deal with writers as diverse and disparate as the Catalano-Spanish writer Juan Marse, the Bulgarian-French philosopher Julia Kristeva and the once-vaunted giant of English literature,Graham Greene, among numerous others, there is much to be enjoyed and learnt, even if some of the works under discussion are unfamiliar to the crime fiction reader and/or scholar to whom the book initially appears to be directed.

Organic chicken product authentication: state-of-the-art and future perspectives

Organic food products are highly susceptible to fraud. Currently, administrative controls are conducted to detect fraud, but having an analytical tool able to verify the organic identity of food would be very supportive. The state-of-the-art in food authentication relies on fingerprinting approaches that find characteristic analytical patterns to unequivocally identify authentic products. While wide research on authentication has been conducted for other commodities, the authentication of organic chicken products is still in its infancy. Challenges include finding fingerprints to discriminate organic from conventional products, and recruiting sample sets that cover natural variability. Future research might be oriented towards developing new authentication models for organic feed, eggs and chicken meat, keeping models updated and implementing them into regulations. Meanwhile, these models might be very supportive to the administrative controls directing inspections towards suspicious fraudulent samples.

KITCHIN, Rob (ed.). Mapping worlds: international perspectives on Social and Cultural Geographies

Rob Kitchin, geógrafo muy activo y prolífico, mantiene una intensa actividad editorial, puesto que dirige colecciones de temas geográficos y forma parte de los comités asesores de varias revistas internacionales de primera línea, entre ellas, Social and Cultural Geography, que se publica bimensualmente desde el año 2000 y de la que es director. Precisamente, en esta revista dedicada a temas relacionados con la geografía cultural y social se halla el origen de este libro, uno de cuyos propósitos iniciales fue desafiar la hegemonía anglosajona que domina el panorama geográfico internacional.

Sistemes logístics de codificació i identificació, i perspectives de futur

Comptar amb sistemes sofisticats de gestió o programes ERP (Enterprise Resource Planning) no és suficient per a les organitzacions. Per a què aquests recursos donin resultats adequats i actualitzats, la informació d’entrada ha de llegir-se de forma automàtica, per aconseguir estalviar en recursos, eliminació d’errors i assegurar el compliment de la qualitat. Per aquest motiu és important comptar amb eines i serveis d’identificació automàtica i col•lecció de dades. Els principals objectius a assolir (a partir de la introducció al lector de la importància dels sistemes logístics d’identificació en un entorn global d’alta competitivitat), són conèixer i comprendre el funcionament de les tres principals tecnologies existents al mercat (codis de barres lineals, codis de barres bidimensionals i sistemes RFID), veure en quin estat d’implantació es troba cadascuna i les seves principals aplicacions. Un cop realitzat aquest primer estudi es pretén comparar les tres tecnologies per o poder obtenir perspectives de futur en l’àmbit de l’autoidentificació. A partir de la situació actual i de les necessitats de les empreses, juntament amb el meravellós món que sembla obrir la tecnologia RFID (Radio Frequency Identification), la principal conclusió a la que s’arribarà és que malgrat les limitacions tècniques dels codis de barres lineals, aquests es troben completament integrats a tota la cadena logística gràcies a l’estandarització i la utilització d’un llenguatge comú, sota el nom de simbologies GTIN (Global Trade Item Number), durant tota la cadena de subministres que garanteixen total traçabilitat dels productes gràcies en part a la gestió de les bases de dades i del flux d’informació. La tecnologia RFUD amb l’EPC (Electronic Product Code) supera aquestes limitacions, convertint-se en el màxim candidat per a substituir els limitats codis de barres. Tot i això, RFID, amb l’EPC, no serà un adequat identificador logístic fins que es superin importants barreres, com són la falta d’estandarització i l’elevat cost d’implantació.

Perspectives for the Spanish Intervention in Macao in the 19th Century

The purpose of this paper is to analyse some essential events concerning the relationship between Spain and Macao in the middle of the 19th century. Macao remained as a privileged spot for the commercial activities of Spain in China after the opening of the international ports agreed upon in the Treaty of Nanjing in 1842. This encouraged Spanish diplomatic representatives to render special attention to the Portuguese enclave. This became the origin of a shocking proposal for the military conquest of Macao and its surrounding territories by one of these representatives, Sinibaldo de Mas. Although this proposal was never taken under consideration, it helps us to better understand the role Macao played in Spanish strategies in China. Years later, Mas participated as a mediator when the Chinese government attempted to regain sovereignty over Macao by paying an economic compensation to Portugal. The involvement of Sinibaldo de Mas in this project has a strong symbolic meaning, making him a key agent in the relations between Spain and Macao in the 19th century.
