High Resolution measurement and mapping of tungstate in waters, soils and sediments using the low-disturbance DGT sampling technique.

Increasing tungsten (W) use for industrial and military applications has resulted in greater W discharge into natural waters, soils and sediments. Risk modeling of W transport and fate in the environment relies on measurement of the release/mobilization flux of W in the bulk media and the interfaces between matrix compartments. Diffusive gradients in thin-films (DGT) is a promising passive sampling technique to acquire such information. DGT devices equipped with the newly developed high-resolution binding gels (precipitated zirconia, PZ, or ferrihydrite, PF, gels) or classic/conventional ferrihydrite slurry gel were comprehensively assessed for measuring W in waters. FerrihydriteDGT can measure W at various ionic strengths (0.001–0.5 mol L−1 NaNO3) and pH (4–8), while PZDGT can operate across slightly wider environmental conditions. The three DGT configurations gave comparable results for soil W measurement, showing that typically W resupply is relatively poorly sustained. 1D and 2D high-resolution W profiling across sediment—water and hotspot—bulk media interfaces from Lake Taihu were obtained using PZDGT coupled with laser ablation ICP–MS measurement, and the apparent diffusion fluxes across the interfaces were calculated using a numerical model.

Cognitive robotics: a new approach to simultaneous localisation and mapping

Most simultaneous localisation and mapping (SLAM) solutions were developed for navigation of non-cognitive robots. By using a variety of sensors, the distances to walls and other objects are determined, which are then used to generate a map of the environment and to update the robot’s position. When developing a cognitive robot, such a solution is not appropriate since it requires accurate sensors and precise odometry, also lacking fundamental features of cognition such as time and memory. In this paper we present a SLAM solution in which such features are taken into account and integrated. Moreover, this method does not require precise odometry nor accurate ranging sensors.

Management and engineering education in the 1950s and 1960s

The career destiny of many graduate engineers is in industry. Quite how well prepared they were for that career became a matter of political importance in the late 1950s and early 1960s as the issue of Britain's relatively poor economic performance grew in salience. This article looks at this preparation with particular reference to management training. It examines the attitudes of those parties most interested in engineering education ‐ the government, industry, the engineering institutions and the educators themselves. All of these saw management training as being part of the formation of at least a portion of professional engineers at some stage in their career. But there was no general agreement between them about what this should consist of or when it should be provided. At the same time broader changes in engineering education were taking place which cut across and to some extent militated against attempts to enhance the role of management training. The result, it is argued, is that by the end of the 1960s little progress had been achieved.

A dynamic role-playing platform for simulations in legal and political education

One big challenge in deploying games-based learning, is the high cost and specialised skills associated with customised development. In this paper we present a serious games platform that offers tools that allow educators without special programming or artistic skills to dynamically create three dimensional (3D) scenes and verbal and non-verbal interaction with fully embodied conversational agents (ECAs) that can be used to simulate numerous educational scenarios. We present evaluation results based on the use of the platform to create two educational scenarios for politics and law in higher education. We conclude with a discussion of directions for the further work.

Towards a Critique of Educative Violence: Walter Benjamin and ‘Second Education’

Although modern systems of mass education are typically defined in their opposition to violence, it has been argued that it is only through an insistent and critical focus upon violence that radical thought can be sustained. This article seeks to take up this challenge in relation to Walter Benjamin’s lesser-known writings on education. Benjamin retained throughout his life a deep suspicion about academic institutions and about the pedagogic, social and economic violence implicated in the idea of cultural transmission. He nonetheless remained committed to the possibility of another kind of revolutionary potential inherent to true education and, when he comes to speak of this in his Critique of Violence, it is remarkable that he describes it as manifesting an educative violence. This article argues that Benjamin’s philosophy works toward a critique of educative violence that results in a distinction between a ‘first’ and ‘second’ kind of education and asks whether destruction might have a positive role to play within pedagogical theories in contrast to current valorisations of creativity and productivity.

Genetic parameters and mapping quantitative trait loci associated with tibia traits in broilers.

Abstract: Selection among broilers for performance traits is resulting in locomotion problems and bone disorders, once skeletal structure is not strong enough to support body weight in broilers with high growth rates. In this study, genetic parameters were estimated for body weight at 42 days of age (BW42), and tibia traits (length, width, and weight) in a population of broiler chickens. Quantitative trait loci (QTL) were identified for tibia traits to expand our knowledge of the genetic architecture of the broiler population. Genetic correlations ranged from 0.56 +/- 0.18 (between tibia length and BW42) to 0.89 +/- 0.06 (between tibia width and weight), suggesting that these traits are either controlled by pleiotropic genes or by genes that are in linkage disequilibrium. For QTL mapping, the genome was scanned with 127 microsatellites, representing a coverage of 2630 cM. Eight QTL were mapped on Gallus gallus chromosomes (GGA): GGA1, GGA4, GGA6, GGA13, and GGA24. The QTL regions for tibia length and weight were mapped on GGA1, between LEI0079 and MCW145 markers. The gene DACH1 is located in this region; this gene acts to form the apical ectodermal ridge, responsible for limb development. Body weight at 42 days of age was included in the model as a covariate for selection effect of bone traits. Two QTL were found for tibia weight on GGA2 and GGA4, and one for tibia width on GGA3. Information originating from these QTL will assist in the search for candidate genes for these bone traits in future studies.

Adolescent females' self-concept and physical education : a Q-sort analysis /

This research illuminates the relationship between female adolescents' self-concept and their experience of physical education. This was accomplished through three stages of interviews and a Qsort. The topics through which the research was categorized included peer support, teachers as significant others, meaningful connections to the body, and curriculum content. During stage one female physical education specialists, curriculum coordinators, and adolescents were interviewed to develop Q-items for the Q-sort. The second stage Involved two groups of females between the ages of 12 and 14 years who participated in the Q-sort. The final stage involved an insight group that consisted of four Q-sort participants who interpreted the highest ranking Q-items. Critical to this research was giving these adolescents the opportunity to voice what was important to them. The results of the research included descriptions of the elements in physical education that were deemed most important by female adolescent students. The topics of "peer support" and "meaningful connections to the body" were ranked the highest. By interpreting the rich insights of the discussion group, it was found that peers were most influential to these young girls. Perceiving and bestowing respect were imperative in this stage of their lives.

Wellness and balance: perceptions amongst female health care professionals negotiating career, family, and continuing education /

The purpose ofthis study was to explore the perceptions of wellness and bidance amongst female health care professionals negotiating career, family aiul continuing education commitments. Five women who met the criteria of having a family (with children), holding a full-time professional career in health care, and who were presently pursuing continuing education were interviewed. This paper begins with the introduction to the topic of research and the questions to be answered. The review of literature explores the theory and research A^ch precede this study and addresses the surrounding areas of: wellness, balance, multiple roles, stress and continuing education. < This study has assumed a qualitative, phenomenological approach. The data collected through the use of individual interviews were analyzed using a two-part process. Analysis using both (a) methodological interpretation and (b) The Listening Guide method has allowed for the uncovering of major themes, and the portrayal of each participant's unique experience. Some of the major themes which emerged from this research include: wellness as multidimensional and fluctuating, making personal sacrifices, the presence of stress, professional as a vital role, and continuing education as something for me. Perhaps the most significant finding this research has identified is the positive role continuing education can hold in the lives of women already negotiating multiple commitments. The notion that continuing education can act as a means of enhancing perceptions of wellness and balance holds a number of implications in theory, practice, and for future research.

Worldview awareness and adult education /

This research derived data from two sets of interviews with 18 participants who were involved in adult education in either a community college or a university. The purpose was to explore their worldview awareness. Through the interviews, the participants shared their understanding of worldview as a term and concept and as something that might be seen to apply in their practice of teaching. The responses indicated that there are three kinds of awareness (noetic, experiential, and integrative) which appeared to develop upon a landscape of constraints and opportunities. Constraints were seen to fall into the 5 broad categories of institutional, circumstantial, self-imposed, other-imposed, and discipline-related constraints. Opportunities for developing awareness were linked to individual experiences and could occur to different extents in many directions, on different occasions, and in different phases of life. Through this research, and in spite of the prevalence of worldview in the human experience, it was foimd that the term and concept have remained on the margins of educational discourse. Consequently, theory, research, and practice have been deprived of a useful and usable concept.

Examining and describing professional development and continuing education in the personal training and fitness industry : sites and issues of disconnect

The following phenomenologically oriented study examines and describes the relevance and effectiveness of professional development and continuing education programs for real-world situations of personal trainers. The participants were personal trainers, facility managers, and persons involved in the accreditation process. Data collection took place in 3 phases. The first phase consisted of the participants completing the PUMP Questionnaire, followed by focus groups with personal trainers and interviews with managers. The study's 3 data sets required reduction via a content analysis by question, content analysis by existential categories, and further thematic analysis using the lived relation existential dimension. The discussion contains the salient sites and issues of disconnect between clients, personal trainers, and facility managers and how they might affect the personal training experience. The intergenerational disconnect emphasized between Boomers as clients and Millennials as personal trainers requires further exploration and dialogue and underscores the need for different approaches to content and delivery of professional development and continuing education experiences for personal trainers and managers of fitness facilities.
