Esta monografía se centra en evaluar mediante un enfoque constructivista, y a partir de una serie de hechos históricos, cómo la identidad construida por Rusia y Georgia fue el detonante de la Guerra de Osetia del Sur en 2008. Para tal objetivo, se partirá del supuesto que este conflicto fue el resultado de las diferencias entre ambos actores que desarrollaron una serie de políticas antagónicas, enmarcadas en una cultura de anarquía hobbesiana la cual se configuró tras la Revolución de las Rosas y la posterior llegada de Mijaíl Saakashvili al poder, puesto que Georgia se convertiría en el principal aliado de occidente en el Cáucaso, basado en un rol anti ruso y disidente de la influencia del Kremlin en la zona, divergiendo con el liderazgo de Rusia el cual se fundamenta en una identidad construida a raíz de su pasado imperial y hegemónico.

The East Asian Winter Monsoon (EAWM) and Siberian High (SH) are inherently related, based on prior studies of instrumental data available for recent decades (since 1958). Here we develop an extended instrumental EAWM index since 1871 that correlates significantly with the SH. These two indices show common modes of variation on the biennial (2-3 year) time scale. We also develop an index of the pressure gradient between the SH and the Aleutian Low, a gradient which critically impacts EAWM variability. This difference series, based on tree-ring reconstructions of the SH and the North Pacific Index (NPI) over the past 400 years, shows that the weakening of this gradient in recent decades has not been unusual in a long-term context. Correlations between the SH series and a tree-ring reconstruction of the El Nino-Southern Oscillation (ENSO) suggest a variable tropical-higher latitude teleconnection.

The overall objective of the research project has been to assess the impact of provider diversity on quality and innovation in the NHS. The specific research aims were to identify the differences in performance between non-profit Third Sector organisations, for-profit private enterprises, and incumbent public sector institutions within the NHS as providers of health care services, as well as the factors that affect the entry and growth of new private and Third Sector providers. The study used both qualitative and quantitative methods based on case studies of four Local Health Economies (LHEs). Qualitative methods included documentary analysis and interviews with key informants and managers of both commissioning and provider organisations. To provide a focus to the study, two tracer conditions were followed: orthopaedic surgery and home health care for frail older people. In the case of hospital inpatient care, data on patient characteristics were also collected from the HES database. The analysis of this data provided preliminary estimates of the effects of provider type on quality, controlling for client characteristics and case mix. In addition, a survey of patient experience in diverse provider organisations was analysed to compare the different dimensions of quality of provision of acute services between incumbent NHS organisations and new independent sector treatment centres. The research has shown that, in respect of inpatient hospital services, diverse providers supply health services of at least as good quality as traditional NHS providers, and that there is ample opportunity to expand their scale and scope as providers of services commissioned by the NHS. The research used patient experience survey data to investigate whether hospital ownership affects the quality of services reported by NHS patients in areas other than clinical quality. The raw survey data appear to show that private hospitals provide higher quality services than the public hospitals. However, further empirical analysis leads to a more nuanced understanding of the performance differences. Firstly, the analysis shows that each sector offers greater quality in certain specialties. Secondly, the analysis shows that differences in the quality of patients’ reported experience are mainly attributable to patient characteristics, the selection of patients into each type of hospital, and the characteristics of individual hospitals, rather than to hospital ownership as such. Controlling for such differences, NHS patients are on average likely to experience a similar quality of care in a public or privately-run hospital. Nevertheless, for specific groups of patients and for specific types of treatments, especially the more straightforward ones, the private sector provides an improved patient experience compared to the public sector. Elsewhere, the NHS continues to provide a high quality service and outperforms the private sector in a range of services and for a range of clients.

The environmental impacts of genetically modified crops is still a controversial issue in Europe. The overall risk assessment framework has recently been reinforced by the European Food Safety Authority(EFSA) and its implementation requires harmonized and efficient methodologies. The EU-funded research project AMIGA − Assessing and monitoring Impacts of Genetically modified plants on Agro-ecosystems − aims to address this issue, by providing a framework that establishes protection goals and baselines for European agro-ecosystems, improves knowledge on the potential long term environmental effects of genetically modified (GM) plants, tests the efficacy of the EFSA Guidance Document for the Environmental Risk Assessment, explores new strategies for post market monitoring, and provides a systematic analysis of economic aspects of Genetically Modified crops cultivation in the EU. Research focuses on ecological studies in different EU regions, the sustainability of GM crops is estimated by analysing the functional components of the agro-ecosystems and specific experimental protocols are being developed for this scope.

The cost of a road construction over its service life is a function of the design, quality of construction, maintenance strategies and maintenance operations. Unfortunately, designers often neglect a very important aspect which is the possibility to perform future maintenance activities. The focus is mainly on other aspects such as investment costs, traffic safety, aesthetic appearance, regional development and environmental effects. This licentiate thesis is a part of a Ph.D. project entitled “Road Design for lower maintenance costs” that aims to examine how the life-cycle costs can be optimized by selection of appropriate geometrical designs for the roads and their components. The result is expected to give a basis for a new method used in the road planning and design process using life-cycle cost analysis with particular emphasis on road maintenance. The project started with a review of literature with the intention to study conditions causing increased needs for road maintenance, the efforts made by the road authorities to satisfy those needs and the improvement potential by consideration of maintenance aspects during planning and design. An investigation was carried out to identify the problems which obstruct due consideration of maintenance aspects during the road planning and design process. This investigation focused mainly on the road planning and design process at the Swedish Road Administration. However, the road planning and design process in Denmark, Finland and Norway were also roughly evaluated to gain a broader knowledge about the research subject. The investigation was carried out in two phases: data collection and data analysis. Data was collected by semi-structured interviews with expert actors involved in planning, design and maintenance and by a review of design-related documents. Data analyses were carried out using a method called “Change Analysis”. This investigation revealed a complex combination of problems which result in inadequate consideration of maintenance aspects. Several urgent needs for changes to eliminate these problems were identified. Another study was carried out to develop a model for calculation of the repair costs for damages of different road barrier types and to analyse how factors such as road type, speed limits, barrier types, barrier placement, type of road section, alignment and seasonal effects affect the barrier damages and the associated repair costs. This study was carried out using a method called the “Case Study Research Method”. Data was collected from 1087 barrier repairs in two regional offices of the Swedish Road Administration, the Central Region and the Western Region. A table was established for both regions containing the repair cost per vehicle kilometre for different combinations of barrier types, road types and speed limits. This table can be used by the designers in the calculation of the life-cycle costs for different road barrier types.

For the past few decades, researchers have increased our understanding of how sound functions within various audio–visual media formats. With a different focus in mind, this study aims to identify the roles and functions of sound in relation to the game form Audio Games, in order to explore the potential of sound when acting as an autonomous narrative form. Because this is still a relatively unexplored research field, the main purpose of this study is to help establish a theoretical ground and stimulate further research within the field of audio games. By adopting an interdisciplinary approach to the topic, this research relies on theoretical studies, examinations of audio games and contact with the audio game community. In order to reveal the roles of sound, the gathered data is analyzed according to both a contextual and a functional perspective. The research shows that a distinction between the terms ‘function’ and ‘role’ is important when analyzing sound in digital games. The analysis therefore results in the identification of two analytical levels that help define the functions and roles of an entity within a social context, named the Functional and the Interfunctional levels. In addition to successfully identifying three main roles of sound within audio games—each describing the relationship between sound and the entities game system, player and virtual environment—many other issues are also addressed. Consequently, and in accordance with its purpose, this study provides a broad foundation for further research of sound in both audio games and video games.

In response to a perceived need for management studies in engineering
undergraduate courses, the Institution of Engineers, Australia (IEAust)
mandated a requirement for 10% of course content to be management
studies in Australia in 1991. In 1996 a major review of engineering
education in Australia recommended that the IEAust move from a course
accreditation regime based on prescribed inputs to one based on
demonstrated graduate attributes. In the move to the new accreditation
system the policy on management studies in engineering undergraduate
courses has become less definitive and more open to interpretation by
individual educational institutions. A survey of recent engineering
graduates suggests that those management skills most highly valued by
graduates were generic professional practice skills, and that more
opportunities to develop these skills in undergraduate studies would be
beneficial. Survey respondents suggested the inclusion in the course of
more real world examples of engineering management, including case
studies, hands-on activities, industry visits, more in-depth coverage of
topics, and presentations from practicing professionals.

This paper discusses and analyses theoretical explanations of risk and risk management in terms of the management of doctoral studies. It deals with the ways in which Government policy, together with contemporary approaches to the bureaucratisation of risk management and the development and imposition of rationalities of risk, are shaping the practices of universities concerning the selection, supervision, support and assessment of doctoral candidates. In particular, the impact of the Research Training Scheme on doctoral studies is discussed as a particular context in which the institutionalisation of risk management occurs.

This research draws on recent studies of student time perception and use.
Case studies are used contrast the time use experiences of tertiary distance
education (on-line) students with tertiary students studying in traditional faceto-face classes with an online component. Previous studies and experience highlight a mismatch between the measurable and hence ”real” amount of time students spend at their computer and online, with the perceived” (and resented) time spent in online learning. This study uses investigates the recognition and application of factors affecting student perception of time spent in studying and learning online. It also compares the effectiveness of these factors when applied to distance education based wholly online classes, and face-to-face classes with an online component.
Some of the factors were measurably successful in reducing students’
perceptions of time “wasted” online, while others produced considerable
insight into face-to-face students perceptions of time used in study. The
factors included much greater focus on the person who was a student and
their expectations and time/life experiences while learning; the support and
use of alternative technologies such as mobile phones as learning and
communication too; a higher level of administrative and academic technical
support for the students; convergence of delivery methods; and strategic
involvement of teaching staff in design and delivery of learner management
systems.

The Gold Standard for education research promotes randomized controlled trials (RCTs) that can produce generalizable knowledge claims across similar problems and situations. Unfortunately, the Gold Standard does not fully recognize the need for developmental research to better understand the problem space, formulate theory and approaches to teaching and learning, and formulate and pursue associated research questions. This developmental research has been a precursor to the development of interventions together with the necessary instrumentation and technologies required to fully investigate these through the more formal evaluative processes imagined by the Gold Standard. This chapter focuses on longitudinal studies that cover a continuum from such developmental research to research that uses control-experimental features to evaluate interventions. These studies attend to a set of issues dealing with developmental progressions and learning trajectories that require investigation over an extended period of time. It will be argued that
these longitudinal studies of a variety of methodological types represent quality research in that rigorous design and implementation produce evidence-based claims. The chapter examines the nature of the relationship between evidence and claims in these studies, to show the possibility of building in control features every bit as strong as those in classic Gold Standard designs. Further, it will be argued that, given the complexity of learning pathways, a simplistic interpretation of RCTs conducted over the shorter term can be misleading in terms of both internal and external validity claims.

This article discusses the recruitment and training of bilingual project workers and their role in data gathering; the level of comprehension of the interviewees with regard to the nature of the task and its alien nature; the contribution of social customs and expectations; the vagaries of language; the researchers' level of comprehension of data collected across a range of languages; the feelings of loss of control by the researchers over the research process; and issues of communication with bilingual project workers. The authors draw on two studies designed to assess the adequacy of questionnaire translations from English into four ethnic minority languages: Cantonese, Punjabi, Urdu and Sylheti. Bilingual project workers were recruited to carry out interviews and focus groups with the lay communities and to feed back results in English to the researchers. The authors conclude that researchers should be aware of the influence of social and contextual factors when carrying out research with ethnic minority participants mediated by bilingual project workers.

In her interesting article, Stoel-Gammon (this issue) reviews studies concerning the interactions between lexical and phonological development. While the focus of the review is on vocabulary production from children acquiring American English, she also suggests that cross-linguistic research be undertaken to examine how universal and language-specific properties affect the interaction between lexical and phonological acquisition. In this regard, Stoel-Gammon referred to the study of Bleses et al. (2008) who found differences in receptive vocabulary development across languages, based on norming studies for the Communicative Development Inventories (Fenson, Marchman, Thal, Dale, Reznick & Bates, 2007). Bleses et al. showed that Danish children were slower in the early comprehension of words (and phrases). It was hypothesized that the phonetic structure of Danish may account for the difference in receptive vocabulary skills in this population (Bleses & Basbøll, 2004).
