Fracture estimation in anisotropic media

A heterogeneous mixture of isotropic elements may appear homogeneous and anisotropic when the scale of its fabric is smaller than the seismic wavelengths that measure it. This fabric can result from thin layering, aligned crystals, anisotropic background stress, aligned fractures, and/or oriented microcracks. Horizontal layering in sedimentary basins and the oceanic crust generates transverse isotropy, a hexagonal symmetry with a vertical symmetry axis, an extremely common form of anisotropy. The elastic properties of transversely isotropic media do not vary with azimuth. With the advent of multi-component seismometers and walk-around experiments, however, azimuthal variation is now frequently observed as well. This azimuthal anisotropy usually results from steeply dipping aligned fractures or microcracks. Realistic earth models must include all the significant constituent anisotropies of fracture systems and the backgrounds in which these fracture systems are embedded. The anisotropy increases in complexity as the number of different systems incorporated into the medium increases . Considering all possible combinations of constituents, a variety of anisotropies can result. For example, embedding a fracture system into an isotropic background can produce anisotropy with a symmetry as simple as hexagonal or as complex as triclinic. Analysis of either fractures or the background requires separating the two anisotropic effects otherwise they interfere. As long as there is at least one symmetry plane in fractured anisotropic media, the contribution of the fractures to the elastic modulus matrix of the background can be removed. The fracture properties can be evaluated by imposing the background symmetry constraints. Once the fracture compliances are obtained, the elastic properties of the unfractured background and the complexity of its symmetry can be determined.
Random forest algorithms for evaluating offensive efficiency in Football

Football is a team sport which has been changing its view towards data-backed decisions in the past decade. In this study, we focus on offensive efficiency in football and use modified random forest algorithms to construct an expected goals metric. The low-scoring nature of the game created a large gap between the overall attempted shots and those which were converted to a goal. The modified methods employed account for the imbalance in the data. We find that using a random forest-quantile classifier outperforms other algorithms in terms of predictive accuracy. The constructed metric assigns a probability of scoring for each shot given some characteristics, including individual skill, spatial-temporal data and defensive ability of the opposing team. We then provide ideas for applications of such a metric and discuss how it can potentially be a useful tool for football clubs.
The Los Alamos suite of relativistic atomic physics codes

The Los Alamos suite of relativistic atomic physics codes is a robust, mature platform that has been used to model highly charged ions in a variety of ways. The suite includes capabilities for calculating data related to fundamental atomic structure, as well as the processes of photoexcitation, electron-impact excitation and ionization, photoionization and autoionization within a consistent framework. These data can be of a basic nature, such as cross sections and collision strengths, which are useful in making predictions that can be compared with experiments to test fundamental theories of highly charged ions, such as quantum electrodynamics. The suite can also be used to generate detailed models of energy levels and rate coefficients, and to apply them in the collisional-radiative modeling of plasmas over a wide range of conditions. Such modeling is useful, for example, in the interpretation of spectra generated by a variety of plasmas. In this work, we provide a brief overview of the capabilities within the Los Alamos relativistic suite along with some examples of its application to the modeling of highly charged ions.
The Jamaican elderly: a socioeconomic perspective and policy implications.

Data from a combined retrospective analysis and cross-sectional community-based survey of 1329 elderly Jamaicans aged 60-97 are used to analyze aspects of aging in Jamaica. "The findings suggest that elderly persons continue to live in families to which they contribute in several ways. Sources of support include the family and informal systems but the quality of the support was not assessed. There was a gender difference in social and economic needs and possible solutions. The study identified the need for a gender specific approach to social and economic policy on ageing. It also identified the need for a life course approach for future generations of elderly persons. And finally research including anthropological research is essential to inform future policy. " (EXCERPT)
Balkan Prehistory: Exclusion, Incorporation and Identity

Douglass Bailey's volume fills the huge gap that existed for a comprehensive synthesis, in English, of the archaeology of the Balkans between 6,500 and 2,000 BC; much research on the prehistory of Eastern Europe was inaccessible to a western audience before now, because of linguistic barriers. Bailey argues against traditional interpretations of the period, which focus on the origins of agriculture and animal breeding. He demonstrates that this was a period when monumental social and material changes occurred in the lives of the people in this region, with new technologies and ways of displaying identity. Balkan Prehistory will be required reading for everyone studying the Neolithic, Copper and early Bronze Ages of Eastern Europe.
Research or teaching? Contradictory demands on Swedish teacher educators and the consequences for the quality of teacher education

Based on a policy analysis and interviews with assistant lecturers and lecturers (with a PhD) who are heavily involved in teacher education, the present article addresses contemporary tensions and challenges in Swedish teacher education. The point of departure is the theoretical framework of mission stretch and the third space professional in teacher education with the aim of investigating how teacher educators experience and navigate their daily work. The findings of the study illustrate the tensions teacher educators experience between research and teaching tasks, between a constant flow of tasks, large student groups, and demands of high-quality teaching. The findings also show a gap between the practical anchoring of some research in teacher education and feelings of tension between teaching practices and the value of research. In conclusion, teacher education would seem to be developing into a cluster of tasks, challenges, expectations, and skills. This indicates that teaching and research are not the only missions and cannot be taken for granted in light of how teachers struggle to define their professional knowledge and value with respect to increasingly strong competitive demands for research performance.
Myth or Reality? Boardroom Diversity in German Blue Chip Companies

As the question of boardroom diversity gains increasing attention both in the media and the academic world, this paper offers a comprehensive analysis of the evolution of boardroom composition of German Dax 30 corporations over a period of 10 years (2001-2010). In contrast to public opinion, results show that supervisory boards of German blue chip companies are light-years away from being considered as diversified. Both the proportions of female and foreign board members remain on a very low level. Furthermore, some national particularities such as widespread multiple board appointments, supervisory boards which are chaired by erstwhile firm managers or similar socio-educational backgrounds of current chairmen seem to be rather the rule than the exception. Whereas an increasing activity of board subcommittees can be observed, supervisory boards themselves hardly change their activity over time with respect to team size or meeting frequencies.

Designing mobile learning activities in the Malaysian HE context: A social constructivist approach

The introduction of mobile learning in higher education institutions (HEIs) in Malaysia is an instinctive course of action in response to the high increase in rates of mobile phone ownership amongst higher education (HE) students. Mobile learning encapsulates learning opportunities undertaken with the usage of the students’ mobile phones. This study aims to explore how mobile learning activities, developed using social constructivist learning principles, can support undergraduate students learning in the context of the study. It identifies the learning opportunities that the different mobile learning activities provide as well as exploring issues and challenges in implementing these mobile learning activities. The results derived from this research are used to inform the development of pedagogical design guidelines for engaging Malaysian HE students via mobile learning activities to support a specific course. As depicted by interpretive paradigm upon which this study is founded, the students’ voices are emphasised as it is justified that the students’ participation is essential to move the technology in directions that they prefer. The methodology is design-based research (DBR) which emphasises the need for cyclic intervention and analysis as part of the research process. Hence, there were two stages of data collection which were designed to explore the students’ perspective on the mobile learning activities. The methods of data collection include a questionnaire (145), students’ blog posts (145) and online interviews (9). The study was implemented with two cohorts of student teachers over a period of two years. The findings of this study indicate that Malaysian HE students are prepared to accept mobile learning to support their study. However, educators must also be wary of issues such as the students’ familiarity in using the selected mobile application. There are several types of mobile learning activities which could be offered namely; contextual, reflective, collaborative, multiple-medium, communication and learning-management. This study contributes to the body of knowledge by providing a) conceptual benchmarks for future studies in the area of mobile learning and learning design, b) a rich insight into the mobile learning development in Malaysian HEIs, c) social constructivist pedagogical guideline considerations, and d) tactical advice for HE practitioners in considering mobile learning.
ZONAL MEAN WINDS IN THE EQUATORIAL MESOSPHERE AND LOWER THERMOSPHERE OBSERVED BY THE HIGH RESOLUTION DOPPLER IMAGER

This paper presents analyses of mesospheric and lower thermospheric zonal mean winds observed by the High Resolution Doppler Imager (HRDI) on the Upper Atmosphere Research Satellite (UARS). Monthly averages of the equatorial zonal mean zonal winds are presented for January 1992 through June 1993. Equatorial zonal winds in the 70–90 km region are dominated by a semiannual oscillation (SAO), ranging from 30 m s−1 (westerly) to −100 m s−1 (easterly). At high latitudes the zonal wind variations are predominantly annual. Above 90 km, the low-latitude flow is easterly at all times, punctuated by a small semiannual variation. This behavior may be related to the deposition of momentum by the diurnal tides.
Talent management and organisational justice: employee reactions to high potential identification

We examined how perceived distributive and procedural justice affected the relationship between an employee's identification as a high potential (drawn from archival data), job satisfaction and work effort. A questionnaire was distributed within one large company among employees who were and employees who were not identified as a high potential (n = 203). The results indicated that perceptions of distributive justice were significantly higher for employees identified as a high potential. Moreover, perceived distributive justice fully mediated the relationship between an employee's identification and his or her level of job satisfaction. The results also revealed that perceptions of procedural justice moderated the relationship between perceived distributive justice and work effort. Theoretical and practical consequences of these findings are discussed.
Avaliação das propriedades psicométricas da escala de rastreamento populacional para depressão CES-D em populações clínica e não-clínica de adolescentes e adultos jovens

A Escala de Depressao do Centro de Estudos Epidemiologicos (CES-D) constitui instrumento de rastreamento elaborado pelo National Institute of Mental Health visando identificar humor depressivo em estudos populacionais. Tem sido amplamente utilizada em diferentes contextos, embora suas propriedades psicometricas nao tenham ainda sido completamente exploradas. Este artigo descreve a validade, a confiabilidade e a analise fatorial da versao da CES-D para o portugues. No que se refere a validadacao concorrente da CES-D, observamos que o melhor desempenho da escala foi obtido quando utilizamos o ponto de corte 15 em estudantes universitarios, e entre farmacodependentes o melhor desempenho deu-se quando utilizamos o ponto de corte 24. A consistencia interna medida pelo alfa de Cronbach foi 0,85. A analise estrutural revelou que duas questoes poderiam ser excluidas da escala por apresentarem baixa correlacao com todas as demais. A analise fatorial resultou em uma solucao de quatro dimensoes, correspondendo a uma variancia explicada de 58,8 por cento, resultados similares aos encontrados em estudos internacionais envolvendo populacao geral
A theoretical framework for the morphodynamics of bedrock channels

Bedrock rivers are characterized by conditions of insufficient sediment supply, wherein the amount of sediment supplied to the channel is less than the channel's sediment transport capacity. Consequently, bedrock channels generally exhibit discontinuous sediment cover, which current approaches to the morphodynamics of alluvial rivers are unable to handle. To fill this gap, we present a theoretical framework in which local sediment transport rates are proportional to the areal concentration of sediment available for transport on the bed and the sediment continuity equation is reformulated to account for temporal changes in areal concentration of sediment on nonalluviated surfaces. We then perform a linear stability analysis that shows that an initially uniform distribution of the areal concentration of sediment on the bed is unstable to small perturbations. This suggests that the sediment cover in bedrock channels tends to concentrate into regions which may eventually be alluviated, in general agreement with experimental observations.
Intepreting Consumer Mythology: A Structural Approach to Consumer Behavior

Consumer behavior depth interviews are grouped with other kinds of story telling—fairy tales, novels, psychological test responses, and myths—as imaginative statements that can be qualitatively interpreted for their functional and symbolic content. Drawing upon the Claude Lévi-Strauss approach to the analysis of myths, a structuralist interpretation illustrates application to the age, sex, and social status dimensions of food consumption.
Assessing residents’ perception for a sustainable co-creation of brand identity in regional destinations

Tourist destinations worldwide have started to pay particular attention to the creation of territorial brands to communicate their identity values to visitors and to differentiate their areas from their competitors. In the academic debate, it is claimed that brand creation needs to be achieved through an integrated and sustainable decision-making process that includes the numerous stakeholders that may be involved in a particular destination. Among the various stakeholders, residents are certainly essential to be considered when it comes to building durable and effective destination brands and sustainable development strategies. Although the importance of residents in place branding has been acknowledged in the literature, there is still a lack of theoretical and empirical research regarding their role in the brand creation process and on their perceptions of the brand identity elements that should be conveyed. The main aim of this study is to address this gap by proposing a conceptual framework that will serve to assess residents’ perception of their own destination identity during the brand development process. This framework is tested empirically in the area of Alto Piemonte and perceptions of residents are assessed with an online questionnaire. Thus, the study provides both theoretical reflections that can be used for teaching and research purposes, as well as empirical evidence that enable to conduct similar investigations in other geographical areas.

An Analysis of the Accounting and Finance Research Productivity in Australia and New Zealand in 1991-2010

We assess the research productivity of the accounting and finance community in Australian and New Zealand higher education institutions (HEIs) during 1991–2010 using 48 high-quality accounting and finance journals. Our finding suggests that the HEIs’ research output steadily increases during the 20-year period. The University of New South Wales, the University of Sydney, Monash University, the University of Melbourne and the University of Queensland are the top-five HEIs. We also find that it is a challenge for an academic staff member to publish multiple articles. If an author is able to manage five total appearances over a 20-year period, he/she is in the top 15 per cent among all authors. Many highly productive authors are able to move to different jobs during the 20-year period.
Ciberacoso mediante teléfono móvil e Internet en las relaciones de noviazgo entre jóvenes

El ciberacoso es un fenomeno ampliamente analizado entre adolescentes, sin embargo en Espana ha sido poco estudiado entre jovenes y particularmente en sus relaciones de noviazgo. Empleando una metodologia cuantitativa este estudio analiza el ciberacoso mediante el telefono movil e Internet en las relaciones de noviazgo en una muestra compuesta por 336 estudiantes universitarios. El analisis de resultados indica que un 57,2% declara haber sido victimizado por su pareja mediante el telefono movil, y un 27,4% a traves de Internet. El porcentaje de chicos victimizados fue mayor que el de las chicas. Un 47,6% declara haber acosado a su pareja a traves del telefono movil, y un 14% a traves de Internet. El porcentaje de chicos que lo ejercio fue superior al de las chicas. Los analisis de regresion muestran la relacion entre haber sido victimizado por la pareja a traves de uno de estos medios y el ejercicio del ciberacoso hacia la pareja mediante el mismo medio tecnologico. Los efectos de interaccion ponen de manifiesto que los chicos victimizados a traves del telefono movil o de Internet se implican, en mayor medida que las chicas victimizadas, como agresores en este fenomeno. Los resultados sugieren una modernizacion en los tipos de violencia que experimenta la juventud en sus relaciones de pareja.
