Time Preferences and Environmental Concern: An Analysis of the Swiss ISSP 2010

This study analyzes the trend of environmental concern in Switzerland using data from the International Social Survey Program (ISSP) 1993, 2000, and 2010. First, we compare the observed trend with indicators of the intensity of public debate regarding the environment. The results show that both the number of articles dealing with environmental issues in print newspapers and the debates in the Swiss parliament strongly increased during the observed period. The ecological awareness of the population, however, remained constant over this time. Second, we scrutinize the "social basis" of environmental concern paying particular attention to individuals' time preferences. Third, we investigate the relationship between environmental concern and proenvironmental behavior, on the one hand, and the relation of concern and the acceptance of governmental regulations, on the other hand.

Improving memory in elderly adults by instructing them in professional actors' learning strategies

This study examined a new type of cognitive intervention. For four weeks, participants (ages 65 to 82) were instructed in professional acting techniques, followed by rehearsal and performance of theatrical scenes. Although the training was not targeted in any way to the tasks used in pre- and post-testing, participants produced significantly higher recall and recognition scores after the intervention. It is suggested that the cognitive effort involved in analyzing and adopting theatrical characters' motivations (and then experiencing those characters' mental/emotional states during performance) is responsible for the observed improvement. A secondary strand of this study showed that participants who were given annotated scripts in which the implied goals of the characters were made explicit demonstrated significantly faster access to the stored material, as measured by a computer latency task.

Effectiveness of healthcare waste management interventions in developing countries

Inefficiencies during the management of healthcare waste can give rise to undesirable health effects such as transmission of infections and environmental pollution within and beyond the health facilities generating these wastes. Factors such as prevalence of diseases, conflicts, and the efflux of intellectual capacity make low income countries more susceptible to these adverse health effects. The purpose of this systematic review was to describe the effectiveness of interventions geared towards better managing the generation, collection, transport, treatment and disposal of medical waste, as they have been applied in lower and middle income countries.^ Using a systematic search strategy and evaluation of study quality, this study reviewed the literature for published studies on healthcare waste management interventions carried out in developing countries, specifically the low and lower middle income countries from year 2000 to the current year. From an initially identified set of 829 studies, only three studies ultimately met all inclusion, exclusion and high quality criteria. A multi component intervention in Syrian Arab Republic, conducted in 2007 was aimed at improving waste segregation practice in a hospital setting. There was an increased use of segregation boxes and reduced rates of sharps injury among staff as a result of the intervention. Another study, conducted in 2008, trained medical students as monitors of waste segregation practice in an Indian teaching hospital. There was improved practice in wards and laboratories but not in the intensive care units. The third study, performed in 2008 in China, consisted of modification of the components of a medical waste incinerator to improve efficiency and reduce stack emissions. Gaseous pollutants emitted, except polychlorodibenzofurans (PCDF) were below US EPA permissible exposure limits. Heavy metal residues in the fly ash remained unchanged.^ Due to the paucity of well-designed studies, there is insufficient evidence in literature to conclude on the effectiveness of interventions in low income settings. There is suggestive but insufficient evident that multi-component interventions aimed at improving waste segregation through behavior modification, provision of segregation tools and training of monitors are effective in low income settings.^

Interview forms for integrating education for conservation in marine protected areas management in Colombia

Environmental Education (EE) is a key component in any marine protected area management. However, its visibility and action plans are still poorly developed and structured as a clear element in management procedures. The objective of this study is to contribute with a methodological route that integrates EE to the existing model of management planning and strategies, taking the Colombian National Natural Parks System as a case study. The creation of the route is proposed as a participatory research with different stakeholders in order to respond to the specific conservation needs and goals for the National Parks System. The EE national diagnosis has shown that its integration within the parks management structure is a first priority need, being a converging result on the two case studies on National Parks from the Pacific Coast of Colombia. The diagnosis also demonstrates that communication, participation, training and evaluation have to be reinforced, linking the community and stakeholders involved in the park management to the whole EE process. The proposed methodology route has been agreed upon by the National Parks staff and incorporates advice and recommendations from different stakeholders, in order to better include the park users. This step will help us to advance toward sustainable management in marine and coastal protected areas elsewhere, taking into account not only the biological but also the social-cultural prism. The main challenges in the management and conservation of coastal and marine ecosystems today are discussed.

Appendix 7: List of species with their distribution ranges restricted to the corresponding phytogeographical region

Understanding species distribution patterns and the corresponding environmental determinants is a crucial step in the development of effective strategies for the conservation and management of plant communities and ecosystems. Therefore, a central prerequisite is the biogeographical and macroecological analysis of factors and processes that determine contemporary, potential, as well as future geographic distribution of species. This thesis has been conducted in the framework of the BIOMAPS-BIOTA project at the Nees Institute of Biodiversity of Plants, which was funded by the German Federal Ministry of Education and Research (BMBF). The study investigated patterns of plants species richness and phytogeographic regions under contemporary environmental conditions and forecasted future climate change in the area of West Africa covering five countries: Benin, Burkina Faso, Côte d'Ivoire, Ghana and Togo. Firstly, geographic patterns of vascular plant species richness have been depicted at a relatively fine spatial resolution based on the potential distribution of 3,393 species. Species richness is closely related to the steep climatic gradient existing in the region with a high concentration of species in the most humid areas in the south and decreases towards the northern drier areas. The investigation of the effectiveness of the existing network of protected areas shows an overall good coverage of species in the study area. However, the proportion of covered species is considerably lower at national extent for some countries, thus calling for more protected areas in order to cover adequately a maximum number of plants species in these countries. Secondly, based on the potential distribution range of vascular plant species, seven phytogeographic regions have been delineated that broadly reflect the vegetation zones as defined by White (1983). However notable differences to the delineation of White (1983) occur at the margins of some regions. Corresponding to a general southward shifted of all regions. And expansion of the Sahel vegetation zone is observed in the north, while the rainforest zone is decreased in the very south.This is alarming since the rainforest shelters a high number of species and a high proportion of range-restricted or endemic species, despite their relatively small extent compared to the other regions. Finally, the evaluation of the potential impact of climate change on plant species richness in the study area, results in a severe loss of future suitable habitat for up to 50% of species per grid cell, particularly in the rainforest region. Moreover, the analysis of the possible shift of phytogeographic regions shows in general a strong deterioration of the West African rainforest. In contrast the drier areas are expanding continuously, although a slight gain in species number can be observed in some particular regions. The overall lesson to retain from the results of this study is that the West African rainforest should be fixed as a high priority area for the conservation of biodiversity of plants, since it is subject to severe contemporary and projected future threats.

Adoption of ISO9001 through supply chain in Vietnam : impacts of FDI and product-related environmental regulation

The objective of the present study is to examine the determinants of ISO 9001 certification, focusing on the effect of Product-related Environmental Regulations on Chemicals (PRERCs) and FDI using the answers to several questions in our Vietnam survey conducted from December 2011 to January 2012. Our findings suggest that PRERCs may help with the improvement in quality control of Vietnamese firms. If Vietnamese manufacturing firms with ISO 9001 certification are more likely to adopt ISO 14001, as well as firms in developed countries, our results indicate that the European chemical regulations may assist in the reduction of various environmental impacts in Vietnam. In addition, we found that FDI promotes the adoption of ISO 9001. If FDI firms in Vietnam certify ISO 14001 after the adoption of ISO 9001, as in the case of Malaysia and the developed economies, FDI firms may also be able to improve environmental performance as a result of ISO 14001.

Nuevos métodos y herramientas para la creación y utilización de recursos multimedia en la educación

La educación y los entornos educativos están en constante evolución. Tanto alumnos como educadores cambian de hábitos, de maneras de aprender, de gustos, de dispositivos que manejan y de aplicaciones que usan regularmente entre otras cosas. Todos estos cambios vienen acompañados y fomentados en gran medida por la evolución paralela que experimenta la tecnología, tanto software en los programas utilizados, como hardware en los dispositivos y capacidades de éstos. La educación debe también adaptarse a estos cambios, tanto personales como tecnológicos y sacar el mayor provecho de ellos. El uso de Sistemas de Gestión del Aprendizaje está muy extendido en todos los centros educativos. Estos sistemas poseen un gran número de características y funcionalidades que permiten desde la aplicación de un modelo didáctico totalmente tradicional en el que el profesor imparte un contenido y los alumnos lo reciben a uno totalmente innovador en el que ocurren procesos totalmente diferentes. Por otro lado, el potencial que ofrecen los recursos multimedia no ha sido completamente aprovechado en la educación y supone una gran oportunidad. Esta tesis doctoral propone un conjunto de métodos y herramientas para la creación y el uso de recursos multimedia en la educación. Para ello el desarrollo de esta tesis parte de la definición de un modelo didáctico social, colaborativo y centrado en el alumno que servirá de hilo conductor y que integrará los diferentes y métodos y herramientas estudiados y desarrollados. En un primer paso se identifican varias herramientas y métodos para el aula, tales son la grabación de clases, donde se crea y posteriormente se mejora un carrito portátil de grabación que da muy buen resultado, las herramientas de grabación de screencast y la videoconferencia. Estas herramientas además se integran en una plataforma colaborativa dando lugar a una arquitectura completa y escalable que permite la realización de dichas actividades y la interconexión sencilla con el Sistema de Gestión del Aprendizaje. A continuación y ya en un entorno totalmente online se desarrolla una nueva plataforma de e-learning llamada Virtual Science Hub (ViSH) que consta de cuatro funcionalidades principales, red social, videoconferencia, repositorio educativo y herramienta de autor. En esta plataforma se aplicaron técnicas de recomendación proactiva tanto de recursos educativos como de otros usuarios similares. Por último se validó el modelo educativo completo usando algunas de las herramientas identificadas y desarrolladas en dos escenarios diferentes con gran éxito. Finalmente, esta tesis discute las conclusiones obtenidas a lo largo de la extensa investigación llevada a cabo y que ha propiciado la consecución de una buena base teórica y práctica para la creación de herramientas y métodos para la generación y el uso de recursos multimedia en la educación. ABSTRACT Education and learning environments are constantly evolving. Students and educators change the things their habits, their ways of learning, the things they like or the devices and applications that they use regularly among other things. All these changes are accompanied and fostered by the parallel evolution that technology experiences, both in the software programs used as in the hardware and capabilities of these devices. Education must also adapt to these changes, both personal and technological and get the most out of them. Learning Management Systems are widely used in all educational centers. These systems have a large number of features and functionalities. They allow from the implementation of a traditional teaching model in which the teacher gives content and students receive it to one absolutely innovative teaching model where totally different processes occur. Furthermore, the potential of multimedia resources has not been fully exploited in education and can be a great opportunity. This thesis proposes a set of methods and tools for the creation and use of multimedia in education. The development of this thesis starts with the definition of a social, collaborative and learner-centered model, that serves as a common thread and that integrates different tools and methods studied and developed. In a first step, several tools and methods for the classroom are identified, such as recording, where a portable kit is created and then improved giving very good results, screencast recording and videoconferencing. These tools also are integrated into a collaborative platform resulting in a complete, scalable architecture that enables the execution of such activities and a simple interconnection with the Learning Management System. In an fully online environment a new e-learning platform called Virtual Science Hub (ViSH) is created. It consists of four main features that combine and complement each other, social network, videoconferencing, educational repository and authoring tool. In this platform proactive recommendation of both educational resources and similar users is applied. In a last step the entire educational model using some of the tools identified and developed is successfully validated in two different scenarios. Finally, this thesis discusses the findings obtained during the extensive research carried out and has led to the achievement of a good theoretical and practical basis for the development of tools and methods for the generation and use of multimedia in education.

Variable threshold algorithm for division of labor analyzed as a dynamical system

Division of labor is a widely studied aspect of colony behavior of social insects. Division of labor models indicate how individuals distribute themselves in order to perform different tasks simultaneously. However, models that study division of labor from a dynamical system point of view cannot be found in the literature. In this paper, we define a division of labor model as a discrete-time dynamical system, in order to study the equilibrium points and their properties related to convergence and stability. By making use of this analytical model, an adaptive algorithm based on division of labor can be designed to satisfy dynamic criteria. In this way, we have designed and tested an algorithm that varies the response thresholds in order to modify the dynamic behavior of the system. This behavior modification allows the system to adapt to specific environmental and collective situations, making the algorithm a good candidate for distributed control applications. The variable threshold algorithm is based on specialization mechanisms. It is able to achieve an asymptotically stable behavior of the system in different environments and independently of the number of individuals. The algorithm has been successfully tested under several initial conditions and number of individuals.

Conservación de plantas regeneradas in vitro y análisis de la variación somaclonal de Cinchona officinalis, Linneo

Cinchona officinalis (Rubiaceae), especie endémica del Valle de Loja, ubicado en la región sur del Ecuador, es un recurso forestal de importancia medicinal y ecológica, además la especie ha sido catalogada como planta nacional y es un ícono de la región sur por su aporte a la farmacopea mundial. Esta especie, entre los siglos XVII-XIX sufrió una gran presión en sus poblaciones debido a la extracción masiva de la corteza para la cura del paludismo. Aunque la actividad extractiva generó grandes ingresos a la Corona Española y a la región Sur del Ecuador, ésta fue poco o nada sustentable ecológicamente, provocando la desaparición de la especie en muchos sitios de la provincia, pues, en su momento, no se consideraron alternativas de recuperación de las poblaciones naturales. Actualmente la extracción y consumo de la corteza en la zona de origen es baja o nula, sin embargo esta zona enfrenta nuevas amenazas. La deforestación a causa de proyectos de desarrollo en infraestructuras, la práctica de actividades agrícolas y de ganadería, y los efectos del cambio climático han ocasionado, en estos últimos años, la fragmentación de los ecosistemas. La mayoría de los bosques del sur del Ecuador se han convertido en parches aislados (los bosques en los que se distribuye C. officinalis no son la excepción) siendo esta la principal causa para que la especie se encuentre en estado de amenaza. Los individuos de la especie tienen una alta capacidad de rebrote y producen semillas durante todo el año; sin embargo la capacidad germinativa y la tasa de sobrevivencia son bajas, además de estas dificultades la especie requiere de la asociación con otras especies vegetales para su desarrollo, lo cual ha limitado su distribución en pequeños parches aislados. Con esta problemática, la recuperación natural de las poblaciones es una necesidad evidente. Varios trabajos y esfuerzos previos se han realizado a nivel local: i. Identificación de la distribución actual y potencial; ii. Determinación de la fenología y fructificación iii. Programas de educación ambiental, iv. Análisis moleculares para determinar la diversidad genética. v. Ensayos de propagación vegetativa; y otras acciones de tipo cultural. No obstante, el estado de conservación y manejo de las poblaciones naturales no ha mejorado significativamente, siendo necesaria la aplicación de estrategias integradas de conservación in situ y ex situ, que permitan la recuperación y permanencia de las poblaciones naturales a largo plazo. El presente trabajo tiene como fin dar alternativas para el cultivo de tejidos in vitro de Cinchona officinalis centrados en la propagación masiva a partir de semillas, análisis de la fidelidad genética y alternativas de conservación de tejidos. Los objetivos específicos que se plantean son: i. Analizar el proceso de germinación y proliferación in vitro. ii. Evaluar la estabilidad genética en explantes cultivados in vitro, mediante marcadores ISSR. iii. Establecer protocolos de conservación in vitro mediante limitación del crecimiento y criopreservación de segmentos nodales y yemas. Los resultados más significativos de esta investigación fueron: i. El desarrollo de protocolos eficientes para mejorar los porcentajes de germinación y la proliferación de brotes en explantos cultivados in vitro. Para evaluar el efecto de los fenoles sobre la germinación, se determinó el contenido total de fenoles y el porcentaje de germinación en semillas de C. officinalis comparados con una especie de control, C. pubescens. Para inducir a proliferación, se utilizaron segmentos nodales de plántulas germinadas in vitro en medio Gamborg (1968) suplementado con diferentes combinaciones de reguladores de crecimiento (auxinas y citoquininas). Los resultados obtenidos sugieren que el contenido de compuestos fenólicos es alto en las semillas de C. officinalis en comparación con las semillas de C. pubescens. Estos fenoles pueden eliminarse con peróxido de hidrógeno o con lavados de agua para estimular la germinación. La formación de nuevos brotes y callos en la mayoría de las combinaciones de reguladores de crecimiento se observó en un período de 45 días. El mayor porcentaje de proliferación de brotes, formación de callos y presencia de brotes adventicios se obtuvo en medio Gamborg (B5) suplementado con 5.0 mg/l 6-bencil-aminopurina y 3.0 mg/l de ácido indol-3-butírico. ii. La evaluación de la fidelidad genética de los explantes obtenidos con distintas combinaciones de reguladores de crecimiento vegetal y diversos subcultivos. Se realizó el seguimiento a los explantes obtenidos de la fase anterior, determinando el índice de multiplicación y analizando la fidelidad genética de los tejidos obtenidos por las dos vías regenerativas: brotación directa y regeneración de brotes a partir de callos. Este análisis se realizó por amplificación mediante PCR de las secuencias ubicadas entre microsatélites-ISSR (Inter simple sequence repeat). El medio Gamborg (B5) con 3.0 mg/l de AIB y 5.0 mg/l de BAP usado como medio de inducción en la primera etapa de cultivo generó el mayor índice de proliferación (11.5). Un total de 13 marcadores ISSR fueron analizados, 6 de éstos fueron polimórficos. El mayor porcentaje de variación somaclonal fue inducido en presencia de 1.0 mg/l 2,4-D combinado con 0.2 mg/l Kin con un 1.8% en el segundo sub-cultivo de regeneración, la cual incrementó a 3.6% en el tercer sub-cultivo. Todas las combinaciones con presencia de 2,4-D produjeron la formación de callos y presentaron variación genética. Por su parte la fidelidad genética se mantuvo en los sistemas de propagación directa a través de la formación de brotes a partir de meristemos preformados. iii. El establecimiento de protocolos de conservación in vitro y crioconservación de segmentos nodales y yemas. Para la conservación limitando el crecimiento, se cultivaron segmentos nodales en los medios MS y B5 en tres concentraciones de sus componentes (25, 50 y 100%); y en medio B5 más agentes osmóticos como el manitol, sorbitol y sacarosa en diferentes concentraciones (2, 4 y 8%); los cultivos se mantuvieron por 12 meses sin subcultivos. Para el establecimiento de protocolos para la crioconservación (paralización del metabolismo) se usaron yemas axilares y apicales a las cuales se les aplicaron los métodos de encapsulación-deshidratación y vitrificación. La efectividad de los protocolos usados se determinó en función de la sobrevivencia, reducción del crecimiento y regeneración. Los resultados obtenidos en este apartado reflejan que un crecimiento limitado puede mantener tejidos durante 12 meses de almacenamiento, usando medio B5 más manitol entre 2 y 8%. En los protocolos de crioconservación, se obtuvo el mayor porcentaje de recuperación tras la congelación en NL en el tratamiento control seguido por el método crioprotector de encapsulación-deshidratación. Este trabajo brinda alternativas para la propagación de C. officinalis bajo condiciones in vitro, partiendo de material vegetal con alta diversidad genética. El material propagado puede ser fuente de germoplasma para la recuperación y reforzamiento de las poblaciones naturales así como una alternativa de producción para las comunidades locales debido a la demanda actual de corteza de la zona de origen para la elaboración de agua tónica. ABSTRACT Cinchona officinalis (Rubiaceae) is endemic to the Loja Valley, located in the southern area of Ecuador. The importance of this plant as medical and ecological resource is so great that it has been designated as the national flower and is an icon of the southern region for its contribution to the world pharmacopoeia. Between XVII-XIX centuries its population suffered great reduction due to massive harvesting of the bark to cure malaria. Although extraction activity generated large revenues to the Spanish Crown and the southern region of Ecuador, this was not ecologically sustainable, causing the disappearance of the species in many areas of the province, because during that time alternatives to prevent extinction and recover natural populations were not taken in account. Currently the extraction and consumption of bark in the area of origin is almost absent, but this species faces new threats. Deforestation due to infrastructure development, the practice of farming and ranching, and the effects of climate change had led to the fragmentation of ecosystems during the recent years. Most of the forests of southern Ecuador have become isolated patches, including those where C. officinalis is diffused. The lack of suitable habitat is today the main threat for the species. The species has a high capacity for regeneration and produces seeds throughout the year, but the germination rate is low and the growth is slow. In addition, the species requires the association with other plant species to develop. All these factors had limited its distribution to small isolated patches. The natural recovery of populations is essential to face this problem. Several studies and previous efforts had been made at local level: i. Identification of current and potential distribution; ii. Phenology determination. iii. Environmental education programs, iv. Molecular analisis to determine the genetic diversity. v. Testing of vegetative propagation; and other actions of cultural nature. Despite these efforts, the state of conservation and management of natural populations has not improved significantly. Implementation of integrated in situ and ex situ conservation strategies for the recovery and permanence of long-term natural populations is still needed. This work aims to provide alternatives for in vitro culture of tissue of Cinchona officinalis focused on mass propagation from seeds, genetic fidelity analysis and tissue conservation alternatives. The specific aims are: i. Analyze the process of germination and proliferation in vitro. ii. To evaluate the genetic stability of the explants cultured in vitro by ISSR markers. iii. Establish protocols for in vitro conservation by limiting growth and cryopreservation of nodal segments and buds. The most significant results of this research were: i. The development of efficient protocols to improve germination rates and proliferation of buds in explants cultured in vitro. To study the effect of phenols on germination, the total phenolic content and percentage germination was measured in C. officinalis and in a control species, C. pubescens, for comparison. The content of phenolic compounds in C. officinalis seeds is higher than in C. pubescens. These phenols can be removed with hydrogen peroxide or water washes to stimulate germination. To analyze the regeneration, we used nodal explants from seedlings germinated in vitro on Gamborg medium (1968) supplemented with different combinations of growth regulators (auxins and cytokinins) to induce proliferation. The formation of new shoots and calluses was observed within a period of 45 days in most combinations of growth regulators. The highest percentage of shoot proliferation, callus formation and adventitious buds were obtained in B5 medium supplemented with 5.0 mg/l 6-benzyl-aminopurine and 3.0 mg/l indole-3-butyric acid. ii. Evaluating genetic fidelity explants obtained with various combinations of plant growth regulators and different subcultures. The genetic fidelity was analyzed in tissues obtained by the two regenerative pathways: direct sprouting and shoot regeneration from callus. This analysis was performed by PCR amplification of the sequences located between microsatellite-ISSR (Inter Simple Sequence Repeat). Among a total of 13 ISSR markers analyzed, 6 were polymorphic. The highest percentage of somaclonal variation was induced in the presence of 1.0 mg/l 2,4-D combined with 0.2 mg/l Kin with 1.8% in the second round of regeneration, and increased to 3.6% in the third round. The presence of 2,4-D induced genetic variation in all the combinations of growth regulators. Meanwhile genetic fidelity remained systems propagation through direct shoot formation from meristems preformed. iii. Establishing conservation protocols in vitro and cryoconservation of nodal segments and buds. For medium-term conservation (limited growth) nodal segments were cultured in MS and B5 media at three concentrations (25, 50 and 100%); we tested B5 medium with different concentrations of osmotic agents such as mannitol, sorbitol and sucrose (2, 4 and 8%); cultures were maintained for 12 months with regular subculturing. To establish protocols for cryoconservation (cessation of metabolism) different methods of encapsulation-dehydration and vitrification were applied to axillary and apical buds. The effectiveness of the used protocols is determined based on the survival, growth and regeneration success. The results show that these tissues can be maintained in storage for 12 months, using B5 medium plus mannitol between 2 and 8%. The cryoconservation protocol with highest percentage of recovery was obtained by contral treatment, followed by freezing in NL with encapsulation-dehydration method. This work provides alternatives for the propagation in vitro of C. officinalis, starting from plant material with high genetic diversity. The obtained material represents a source of germplasm to support the recovery and strengthening of natural populations as well as a creation of alternative sources for local communities due to the current demand of bark for the preparation of tonic water.

Investigating and Understanding Student Learning Outcomes in an Online and Face-to-Face Graduate Level Legal Administration Course: An Embedded Mixed Methods Design

Online education is a new teaching and learning medium with few current guidelines for faculty, administrators or students. Its rapid growth over the last decade has challenged academic institutions to keep up with the demand, while also providing a quality education. Our understanding of the factors that determine quality and effective online learning experiences that lead to student learning outcomes is still evolving. There is a lack of consensus on the effectiveness of online versus face-to-face education in the current research. The U.S. Department of Education conducted a meta-analysis in 2009 and concluded that student-learning outcomes in online courses were equal to and, often times, better than face-to-face traditional courses. Subsequent research has found contradictory findings, and further inquiry is necessary. The purpose of this embedded mixed methods design research study is to further our understanding of the factors that create quality and successful educational outcomes in an online course. To achieve this, the first phase of this study measured and compared learning outcomes in an online and in class graduate-level legal administration course. The second phase of the study entailed interviews with those students in both the online and face-to-face sections to understand their perspectives on the factors contributing to learning outcomes. Six themes emerged from the qualitative findings: convenience, higher order thinking, discussions, professor engagement, professor and student interaction, and face-to-face interaction. Findings from this study indicate the factors students perceive as contributing to learning outcomes in an online course are consistent among all students and are supported in the existing literature. Higher order thinking, however, emerged as a stronger theme than indicated in the current research, and the face-to-face nature of the traditional classroom may be more an issue of familiarity than a factor contributing to learning outcomes. As education continues to reach new heights and developments in technology advance, the factors found to contribute to student learning outcomes will be refined and enhanced. These developments will continue to transform the ways in which we deliver and receive knowledge in both traditional and online classrooms. While there is a growing body of research on online education, the field’s evolution has unsettled earlier findings and posed new areas to investigate.

How can directories of open access repositories improve the reuse of learning objects in building engineering?

This paper studies the use of directories of open access repositories worldwide (DOARW) to search Spanish repositories containing learning objects in the field of building engineering (BE). Results show that DOARW are powerful tools, but deficiencies (indicated in this study) have to be solved in order to obtain more accurate searches, and to facilitate repository-finding for potential users who are seeking learning objects (LOs) for reuse. Aiming to contribute to the promotion of the reuse of Spanish LOs, this study exposes to the academic community all existing Spanish repositories with LOs, and in particular, the repositories that contain LOs in the field of BE. This paper also studies the critical mass of available content (LOs) in the field of BE in Spain. It has been found to be low.
