The issue, with international and national overtones, of direct relevance to the present study, relates to the shaping of beginning teachers’ identities in the workplace. As the shift from an initial teacher education programme into initial practice in schools is a period of identity change worthy of investigation, this study focuses on the transformative search by nine beginning primary teachers for their teaching identities, throughout the course of their initial year of occupational experience, post-graduation. The nine beginning teacher participants work in a variety of primary school settings, thus strengthening the representativeness of the research cohort. Privileging ‘insider’ perspectives, the research goal is to understand the complexities of lived experience from the viewpoints of the participating informants. The shaping of identity is conceived of in dimensional terms. Accordingly, a framework composed of three dimensions of beginning teacher experience is devised, namely: contextual; emotional; temporo-spatial. Data collection and analysis is informed by principles derived from sociocultural theories; activity theory; figured worlds theory; and, dialogical self theory. Individual, face-to-face semi-structured interviews, and the maintenance of solicited digital diaries, are the principal methods of data collection employed. The use of a dimensional model fragments the integrated learning experiences of beginning teachers into constituent parts for the purpose of analysis. While acknowledging that the actual journey articulated by each participant is a more complex whole than the sum of its parts, key empirically-based claims are presented as per the dimensional framework employed: contextuality; emotionality; temporo-spatiality. As a result of applying the foci of an international literature to an under-researched aspect of Irish education, this study is offered as a context-specific contribution to the knowledge base on beginning teaching. As the developmental needs of beginning teachers constitute an emerging area of intense policy focus in Ireland, this research undertaking is both relevant and timely.

This paper presents our efforts to bridge the gap between mobile context awareness, and mobile cloud services, using the Cloud Personal Assistant (CPA). The CPA is a part of the Context Aware Mobile Cloud Services (CAMCS) middleware, which we continue to develop. Specifically, we discuss the development and evaluation of the Context Processor component of this middleware. This component collects context data from the mobile devices of users, which is then provided to the CPA of each user, for use with mobile cloud services. We discuss the architecture and implementation of the Context Processor, followed by the evaluation. We introduce context profiles for the CPA, which influence its operation by using different context types. As part of the evaluation, we present two experimental context-aware mobile cloud services to illustrate how the CPA works with user context, and related context profiles, to complete tasks for the user.

En el campo de la matemática educativa, el concepto de periodicidad es un tema muy poco explorado, a pesar de encontrarse inmerso prácticamente en el currículo escolar de la matemática. Este concepto es ampliamente utilizado en diversos tópicos de matemáticas, sin embargo, solo existe poco trabajo de corte epistemológico al respecto, donde se encuentra el trabajo de Shama (1998), este estudio cognitivo nos plantea una problemática sobre la comprensión del estudiante, cuando éste concibe la periodicidad como un proceso y no puede transformarla en objeto. Esto conduce al estudiante a relacionar fenómenos no periódicos como periódicos y a tener preferencia por identificar un periodo de un fenómeno periódico que no es necesariamente en forma correcta. La problemática es retomada para la investigación, considerando los contextos discreto y continuo del concepto. El objetivo es diseñar una situación de tal forma que el estudiante de una nueva explicación sobre la concepción de proceso y pueda alcanzar su transformación al objeto del concepto de periodicidad. Para tal propósito se ha formulado una epistemología de la periodicidad, donde se han hallados ciertos elementos (repetición regular, desplazamiento lineal como el argumento de los fenómenos periódicos, y el comportamiento periódico de una función como un argumento contextual, la manifestación del movimiento en un todo y no en un momento, que permitan la construcción de la periodicidad. El concepto de periodicidad generalmente es tratado en el currículo como una propiedad de cierta clase de funciones llamadas periódicas. Sin embargo es factible pensar la orientación del concepto de periodicidad a través de la noción de comportamiento tendencial de las funciones, donde la epistemología del concepto esté basada en situaciones de tendencia de un comportamiento periódico. De la epistemología de la periodicidad tiene como propósito ser la base de una descomposición genética que incluya los elementos y su relación. Nuestro marco teórico en la investigación es el de la teoría APOE (Acción, Proceso, Objeto, Esquema) y el diseño de actividades, su implementación y la recolección de datos con estudiantes de precálculo y cálculo, a través de la metodología que señala la propia teoría, el ciclo ACE. Los resultados se presentan en la presentación de la investigación.

Purpose – The purpose of this paper is to present an analysis of media representation of business ethics within 62 international newspapers to explore the longitudinal and contextual evolution of business ethics and associated terminology. Levels of coverage and contextual analysis of the content of the articles are used as surrogate measures of the penetration of business ethics concepts into society. Design/methodology/approach – This paper uses a text mining application based on two samples of data: analysis of 62 national newspapers in 21 countries from 1990 to 2008; analysis of the content of two samples of articles containing the term business ethics (comprised of 100 newspaper articles spread over an 18-year period from a sample of US and UK newspapers). Findings – The paper demonstrates increased coverage of sustainability topics within the media over the last 18 years associated with events such as the Rio Summit. Whilst some peaks are associated with business ethics scandals, the overall coverage remains steady. There is little apparent use in the media of concepts such as corporate citizenship. The academic community and company ethical codes appear to adopt a wider definition of business ethics more akin to that associated with sustainability, in comparison with the focus taken by the media, especially in the USA. Coverage demonstrates clear regional bias and contextual analysis of the articles in the UK and USA also shows interesting parallels and divergences in the media representation of business ethics. Originality/value – A promising avenue to explore how the evolution of sustainability issues including business ethics can be tracked within a societal context.

In this paper, we present a new approach to visual speech recognition which improves contextual modelling by combining Inter-Frame Dependent and Hidden Markov Models. This approach captures contextual information in visual speech that may be lost using a Hidden Markov Model alone. We apply contextual modelling to a large speaker independent isolated digit recognition task, and compare our approach to two commonly adopted feature based techniques for incorporating speech dynamics. Results are presented from baseline feature based systems and the combined modelling technique. We illustrate that both of these techniques achieve similar levels of performance when used independently. However significant improvements in performance can be achieved through a combination of the two. In particular we report an improvement in excess of 17% relative Word Error Rate in comparison to our best baseline system.

In this study, we examined the relationship between national identification and anti-immigrant prejudice in a multilevel analysis of ISSP survey data from 37,030 individuals in 31 countries. We argue that this relationship depends on how national groups are defined by their members. Across the 31 national samples, the correlation between national identification and prejudice ranged from weakly negative (-.06) to moderately positive (.37). The relationship was significantly stronger in countries where people on average endorsed a definition of national belonging based on language, and weaker where people on average defined the nation in terms of citizenship. These effects occurred at a national rather than individual level, supporting an explanation in terms of the construction of nationality that prevails in a given context. Endorsement of the ancestry-based criteria for nationality was positively associated with prejudice, but only at the individual level.
