Damage in the English Law of Negligence
Authors: Nolan Donal 
Published: November 2013

AbstractAlthough foundational to the tort law of both common law and civil law countries, the concept of damage has been the object of surprisingly little analysis by academics in the common law world. The aim of this article is to redress the balance somewhat by looking more closely at the meaning of damage in the English law of negligence. The first part of the article consists of general observations on the damage concept. It is argued that it is impossible to devise a meaningful general definition of damage, that damage is not the same thing as loss, and that the damage concept is compatible with rights-based analysis of negligence law. The remainder of the article is devoted to consideration of the two most common forms of damage, personal injury and physical damage to property. It is argued that a central idea underpinning both these routine forms of damage is that of ‘impairment’ and that both forms of damage are subject to de minimis principles. As regards personal injury, particular attention is paid to the forms of psychiatric injury which ground a negligence claim. Finally, it is argued that for property to be damaged there must be a physical change in the property which impairs its utility or value, and that merely to incapacitate property is not to damage it. Although the primary focus is on English law (and the common law more generally), some comparative observations are made.

Published: November 2013

In this article we approach the topic of collaborative learning by means of the creation and maintenance of personal learning environments and networks (PLE and PLN) and their integration within institutional virtual learning environments (VLE) as strategies to enhance and foster collaborative learning. We take an educational point of view: the student learns independently and carries out activities in groups to achieve common goals. Our aim is to experiment with didactical methodologies of integration between the institutional VLE and PLE, and to analyze the university students’ construction of PLE. Due to its importance in facilitating and fostering collaborative learning, special emphasis is placed on the construction of the personal learning network. We performed a design-based research on an academic course for Primary teachers. The results show that the students construct their PLE and PLN using newly acquired knowledge and that an appropriate methodological integration takes place between these environments and the institutional VLE for integrated learning. As conclusion, we propose an integrative methodological model for collaborative learning as a good practice.
El aprendizaje colaborativo se puede afrontar desde diferentes estrategias. En este artículo contemplamos la creación y mantenimiento de entornos y redes personales de aprendizaje (PLEs y PLNs) y su integración en entornos virtuales institucionales de aprendizaje (EVEA) como estrategias que facilitan y promueven el aprendizaje colaborativo, siempre desde una visión educativa en la que el alumno es autónomo en su propio aprendizaje y trabaja para el logro de metas comunes mediante la realización de actividades de forma conjunta en grupos, existiendo interdependencias positivas. Los objetivos de este trabajo son experimentar con metodologías didácticas de integración del EVEA y los PLEs, y analizar la construcción del PLE por parte de los alumnos universitarios, haciendo especial énfasis en la construcción de la red personal de aprendizaje. Para ello se empleó una metodología de diseño y desarrollo, en una asignatura universitaria de los estudios de maestro de Primaria. Los resultados de la experiencia apuntan a que los alumnos construyen sus PLEs y PLNs en base a sus nuevos conocimientos adquiridos y se produce una adecuada integración metodológica entre esos entornos y el EVEA para el aprendizaje integrado. Como conclusión proponemos un modelo de organización metodológica de integración para el aprendizaje colaborativo a modo de buena práctica.

Published: November 2013

This paper presents an exploratory analysis of the experience of educational innovation in the configuration of a social learning network in a subject for the Education degree course at the University of Santiago de Compostela (Spain). This innovation is based on the premise of student-centered teaching (independent learning, self-regulated, authentic and breaking boundaries between formal and informal areas) enriched with collaborative activities. The study aims to analyze the intensity and relevance of the student´s contributions in this collaborative framework. We used learning analytics tools with two types of techniques: social network analysis (SNA) and information extraction, to measure the intensity, centrality and relevance of collaboration among students. The results obtained allow us to confirm: 1) The consistency and coherence between the pedagogical approach and the option of using a social network in university education; 2) A dense network with a high level of interaction, a moderate degree of centrality and a low centralization index (structure moves away from star), with a group with the capacity to influence the rest (degree of betweenness); 3) High level of relevance to the content analyzed; 4) The usefulness of learning analytics techniques to guide teacher decision-making.
El presente trabajo analiza, de forma exploratoria, la experiencia de innovación docente en la configuración de una red social de aprendizaje en una asignatura del Grado de Pedagogía de la Universidad de Santiago de Compostela. La innovación se justifica en las premisas de la enseñanza centrada en el alumno (aprendizaje autónomo, autorregulado y auténtico, ruptura de fronteras entre ámbitos formales e informales), enriquecida con actividades colaborativas. El estudio pretende analizar la intensidad y pertinencia de las aportaciones del alumnado en este marco colaborativo. Para ello se han utilizado herramientas informáticas de la analítica del aprendizaje (learning analytics) con dos tipos de técnicas: análisis de redes sociales y extracción de información, que dan cuenta de la intensidad, centralidad y relevancia de la colaboración entre los estudiantes. Los resultados obtenidos posibilitan concluir: 1) la consistencia y coherencia entre la propuesta pedagógica y la opción de utilizar una red social en la enseñanza universitaria; 2) la existencia de una red densa con alto nivel de interacción, grado de centralidad medio e índice de centralización bajo (estructura que se aleja de la forma estrella), con un grupo con capacidad de influencia en el resto (grado de intermediación); 3) alto nivel de pertinencia de los contenidos analizados; 4) la utilidad de las técnicas de analítica de aprendizaje para orientar la toma de decisiones del docente.
Media literacy for older people facing the digital divide: The e-inclusion programmes design
Authors: Abad-Alcalá Leopoldo 
Published: November 2013

This article is based on the fact that the Spanish population is aging, and is second only to Japan in its total number of senior citizens. Given this situation and the omnipresence of new technologies in everyday life, the use of Internet and ICT for older people is essential. The latest report by IMSERSO shows that only 15.6% of people aged be tween 65 and 74 connected to the Internet in the 3-month period measured. The data seem to show that there is a generational digital divide to be overcome. The studies that have addressed this issue have focused more on regional and specific aspects of the relationship between age and Internet use intensity, and these studies use age ranges as criteria. Other studies have introduced variables such as seniors’ economic situation or educational level. With this in mind, public policies have sought to reduce this generational digital divide through a number of media literacy and e-learning projects but without success due to their poor methodological approach. This paper proposes a number of new methodological approaches to tackle the design of digital literacy programs for older people based on criteria such as degree of autonomy and the possibilities for enjoying everyday life, proposing the development of programs based on contextualism, incrementalism, motivation and absorption processes.
Tras la japonesa, la población española es la segunda población que más envejece. Ante esta situación y la omnipresencia de las nuevas tecnologías, el uso de Internet y las TIC en la vida cotidiana se hace imprescindible para las personas mayores. El último informe del IMSERSO establecía que solo se habían conectado a Internet en los últimos tres meses un 15,6% de las personas entre 65 y 74 años. Estos datos muestran la existencia de una brecha digital de carácter generacional que debe ser superada. Los estudios que han abordado esta problemática se han centrado más en aspectos regionales, y los específicos sobre la relación entre edad e Internet han abordado solo la intensidad de uso vinculada a intervalos de edades. Otros estudios han introducido variables como el nivel económico o educativo. Frente a esta realidad, las políticas públicas han pretendido disminuir esta brecha digital generacional mediante diferentes proyectos de alfabetización mediática y e-learning, sin lograr su objetivo por el deficiente planteamiento metodológico de los cursos. Este artículo propone una serie de nuevas perspectivas metodológicas a la hora de abordar el diseño de programas de alfabetización digital de las personas mayores basadas en criterios tales como el grado de autonomía o falta de la misma para la vida cotidiana así como el desarrollo de programas basados en el contextualismo, incrementalismo, motivación y proceso de absorción.

IntroductionAdherence to HIV antiretroviral therapy (ART) is a critical determinant of HIV‐1 RNA viral suppression and health outcomes. It is generally accepted that HIV‐related stigma is correlated with factors that may undermine ART adherence, but its relationship with ART adherence itself is not well established. We therefore undertook this review to systematically assess the relationship between HIV‐related stigma and ART adherence.MethodsWe searched nine electronic databases for published and unpublished literature, with no language restrictions. First we screened the titles and abstracts for studies that potentially contained data on ART adherence. Then we reviewed the full text of these studies to identify articles that reported data on the relationship between ART adherence and either HIV‐related stigma or serostatus disclosure. We used the method of meta‐synthesis to summarize the findings from the qualitative studies.ResultsOur search protocol yielded 14,854 initial records. After eliminating duplicates and screening the titles and abstracts, we retrieved the full text of 960 journal articles, dissertations and unpublished conference abstracts for review. We included 75 studies conducted among 26,715 HIV‐positive persons living in 32 countries worldwide, with less representation of work from Eastern Europe and Central Asia. Among the 34 qualitative studies, our meta‐synthesis identified five distinct third‐order labels through an inductive process that we categorized as themes and organized in a conceptual model spanning intrapersonal, interpersonal and structural levels. HIV‐related stigma undermined ART adherence by compromising general psychological processes, such as adaptive coping and social support. We also identified psychological processes specific to HIV‐positive persons driven by predominant stigmatizing attitudes and which undermined adherence, such as internalized stigma and concealment. Adaptive coping and social support were critical determinants of participants’ ability to overcome the structural and economic barriers associated with poverty in order to successfully adhere to ART. Among the 41 quantitative studies, 24 of 33 cross‐sectional studies (71%) reported a positive finding between HIV stigma and ART non‐adherence, while 6 of 7 longitudinal studies (86%) reported a null finding (Pearson's χ2=7.7; p=0.005).ConclusionsWe found that HIV‐related stigma compromised participants’ abilities to successfully adhere to ART. Interventions to reduce stigma should target multiple levels of influence (intrapersonal, interpersonal and structural) in order to have maximum effectiveness on improving ART adherence.

IntroductionThe African American church is a highly influential institution with the potential to greatly increase the reach of HIV prevention interventions and address HIV‐related stigma in US African American communities. However, there are few studies on HIV‐related stigma and African American church populations. This study explored HIV‐related stigma among church and community members participating in an HIV education and testing intervention pilot study in African American churches, named Taking It to the Pews.MethodsFour African American churches located in Kansas City, MO and KS, were randomized to either intervention or comparison groups. Churches assigned to the intervention group received religiously tailored HIV education, testing and compassion messages/activities (e.g., sermons, brochures/church bulletins, testimonials) via the Taking It to the Pews HIV Tool Kit. Comparison churches received non‐religiously tailored HIV information. HIV‐related stigma was assessed with 543 church members and with community members served through church outreach services (e.g., food/clothing pantries, social services) in the four churches. Participants completed surveys at baseline, 6 months and 12 months to assess their HIV‐related stigma beliefs, exposure to intervention components and satisfaction with the study.ResultsAt baseline, HIV‐related stigma beliefs were similar across experimental groups and were quite low. Mean HIV‐related stigma scores were not significantly different between experimental groups at 6 months (p=0.92) or at 12 months (p=0.70). However, mean HIV‐related stigma scores within both groups showed decreasing trends at six months, which approached significance. Analysis of previously studied HIV‐related stigma factors (e.g., age, gender, income, HIV knowledge, religiosity) did not yield changes in the null findings. Intervention group participants were highly exposed to several intervention components (sermons, HIV resource tables, posters, brochures/church bulletins). Overall, participants were highly satisfied with the intervention pilot study.ConclusionsAfrican American churches may be well positioned to increase the reach of HIV prevention interventions to church and community members and could serve an important role in addressing HIV‐related stigma in their church communities. Future research is needed on measuring HIV‐related stigma beliefs and on testing intensive, scalable, religiously tailored HIV interventions to impact HIV‐related stigma in African American churches.
Sexual dimorphism in the size and shape of the os coxae and the effects of microevolutionary processes
Authors: Betti Lia 
Published: November 2013

ABSTRACTSexual dimorphism in the human pelvis has been studied widely for forensic purposes, but it is still unclear to what extent it varies among human populations. There is evidence that microevolutionary processes, both neutral (i.e., population history) and selective (e.g., thermoregulatory adaptation and size‐related obstetrical constraints) contribute to explain pelvic variation among populations, but the extent to which these factors affect pelvic sexual dimorphism is unknown. In this study, I analyze sexual dimorphism of the os coxae in 20 globally distributed human populations, using 3D morphometric data to separate the size and shape components of sexual differences. After evaluating population differences in the degree and pattern of sexual dimorphism, I test for the effect of population history, climate, and body size in shaping global diversity. The results show that size and shape dimorphism follow different patterns. Coxal size dimorphism is generally quite consistent through populations, with males bigger than females, but it appears to be reduced in small‐bodied populations, possibly in relation to obstetrically‐related selective pressures for a spacious birth canal. Beyond a general species‐wide pattern of shape dimorphism, commonly used for forensic sex determination, other aspects of sexual differences in coxal shape vary among human populations, reflecting the effects of neutral demographic processes and climatic adaptation.

Published: November 2013

AbstractPharmaceutical antibiotics are not easily removed from water by conventional water‐treatment technologies and have been recognized as new emerging pollutants. Herein, we report the synthesis of clickable azido periodic mesoporous organosilicas (PMOs) and their use as adsorbents for the adsorption of antibiotics. Ethane‐bridged PMOs, functionalized with azido groups at different densities, were synthesized by the co‐condensation of 1,2‐bis(trimethoxysilyl)ethane (BTME) and 3‐azidopropyltrimethoxysilane (AzPTMS), in the presence of nonionic‐surfactant triblock‐copolymer P123, in an acidic medium. Four different alkynes were conjugated to azide‐terminated PMOs by means of an efficient click reaction. The clicked PMOs showed improved adsorption capacity (241 μg g−1) for antibiotics (ciprofloxacin hydrochloride) compared with azido‐functionalized PMOs because of the enhanced π–π stacking interactions. These results indicate that click reactions can introduce multifunctional groups onto PMOs, thus demonstrating the great potential of PMOs for environmental applications.

Published: November 2013

ABSTRACTNew stereological assessments of lateral geniculate nucleus (LGN) neuron numbers and volumes in five New World primates (Cebus apella, Saguinus midas niger, Alouatta caraya, Aotus azarae, and Callicebus moloch) and compiled LGN volumes for an additional 26 mammals were analyzed for a better understanding of visual system evolution. Both the magnocellular (M)‐ and the parvocellular (P)‐cell populations scale allometrically with brain volume in primates, P cells with a significantly higher slope such that, for every increase in M neuron number, P neuron numbers more than double (ln scale; y = 0.89x + 2.42R2 = 0.664). In diurnal primates, the ratio of P to M cells was slightly but significantly higher than in nocturnal primates. For all mammals, including primates, LGN volume was unrelated to nocturnal or diurnal niche but showed marked differences in slope and intercept depending on taxonomic group. The allometric scaling of M and P cells can be related to the order of neurogenesis, with late‐generated P cells increasing with positive allometry compared with the earlier‐generated M cells. This developmental regularity links relative foveal representation to relative isocortex enlargement, which is also generated late. The small increase in the P/M cell ratio in diurnal primates may result from increased developmental neuron loss in the M‐cell population as it competes for limited termination zones in primary visual cortex.

Optimizing olive harvest time under hot climatic conditions of Jordan Valley, Israel

Published: November 2013

Global climate change leads to the exposure of olive orchards to higher temperatures than in the past. We followed yield and quality parameters of olive oils from Barnea, Coratina, and Picual, under hot climatic conditions through different levels of ripeness. Oil yield per tree increased throughout the monitoring period due to continuous oil accumulation. Toward the last harvest date, significant fruit drop occurred, which resulted in substantial loss in oil yield. Maximal oil yield was obtained in Barnea at a maturity index of 2.1–2.5, in Coratina at 2.3 and in Picual at 3.2. A reduction in quality parameters was found with delay of harvest date: free fatty acid content increased and the ratio of monounsaturated to polyunsaturated fatty acid declined, but only in one season. Nevertheless, all parameters remained within the trade standard for extra virgin olive oil (EVOO). In contrast to most previous studies, no consistent reduction was observed in total polar phenol content in the oils. Hence, maximizing oil yield should be the main criterion for the determination of harvest date under these conditions. It is therefore suggested that olives exposed to hot climate be harvested earlier than those in typical Mediterranean climate areas.Practical applications: Harvest timing has a strong effect on both oil yield and quality. However, in most of the studies published on the topic until now only a sample of fruit was taken to determine oil accumulation and quality, but little or no information is available on oil yield at tree level, which is an important parameter from the grower's perspective. Moreover, this study describes changes in oil yield and quality along the ripening period, under hot climatic conditions prevailing in Jordan Valley. The Mediterranean basin region, where more than 90% of the world's olive oil is produced is expected to be exposed to higher temperatures in the future due to global climate changes. The current work provides information on the effect of those unfavorable growing conditions on oil production and quality. One of the major findings is the necessity to harvest early (in a relatively low ripening index) under those conditions.
