Non-native English-speaking English language teachers: history and research

Although the majority of English language teachers worldwide are non-native English speakers, no research was conducted on these teachers until recently. After the pioneering work of Robert Phillipson in 1992 and Peter Medgyes in 1994, nearly a decade had to elapse for more research to emerge on the issues relating to non-native English teachers. The publication in 1999 of George Braine's book Nonnative educators in English language teaching appears to have encouraged a number of graduate students and scholars to research this issue, with topics ranging from teachers' perceptions of their own identity to students' views and aspects of teacher education. This article compiles, classifies, and examines research conducted in the last two decades on this topic, placing a special emphasis on World Englishes concerns, methods of investigation, and areas in need of further attention.

Análisis discursivo de las actitudes lingüísticas de los escolares de origen inmigrante en Cataluña

La continua llegada de población inmigrante a los países de la Europa Occidental está produciendo transformaciones en estas sociedades. Evidentemente, la sociedad catalana no es ajena a estos cambios y, año tras año, ve incrementado el número de recién llegados/ as procedentes de orígenes geográficos, culturales y lingüísticos muy diversos. Estas personas, en ocasiones sin un conocimiento previo, se encuentran con las peculiaridades socioculturales y lingüísticas de la sociedad receptora. En el caso de Cataluña, nos interesa destacar la cuestión lingüística, a la cual se han dedicado muchos esfuerzos durante los últimos años en un intento de acercarse a una situación de normalidad en lo referente al conocimiento y uso de la lengua catalana. En el presente artículo se presentan los principales resultados de una investigación centrada en el análisis de los discursos sobre los que anclan las actitudes lingüísticas de los escolares de origen inmigrante en Cataluña. La técnica de investigación social utilizada ha sido la entrevista en profundidad semidirigida, realizando el análisis del contenido de las mismas a partir del «Análisis de contenido temático basado en categorías» (Bardin, 1986). Las conclusiones más relevantes indican que, por encima del Área de Origen o la Condición Lingüística Familiar, la principal variable que permite articular los discursos detectados es la que se puede denominar «Satisfacción y Percepción de Valoración e Integración Escolar y Social», de tal manera que los jóvenes de origen inmigrante que se sienten más valorados e integrados escolar y socialmente desarrollan mejores actitudes hacia la lengua catalana y castellana. Este hecho tiene claras repercusiones respecto las generalizaciones reduccionistas y estereotipadas que vinculan un área de origen con unas determinadas actitudes hacia las lenguas oficiales en Cataluña, así como de cara a la política lingüística y las ideologías lingüísticas de la sociedad en general.

Involvement of family physicians in structured programs for chronic diseases or multi-morbidity in Switzerland.

The increasing prevalence of chronic diseases and multi-morbidity represents challenges for health systems worldwide. In that perspective, the current organization of healthcare delivery, fragmentation of care, limited use of evidence-based guidelines and patients'insufficient empowerment are some reasons explaining the current limited effectiveness of the management of chronically ill patients. Based on theoretical models such as the Chronic Care Model (CCM), initiatives targeting improvements in the care of patients with chronic diseases have been implemented worldwide since more than a decade. Their development in Switzerland, a health system where more than half of practices are still single handed [6], is only recent and infrequent. Structured programs for patients with chronic diseases or multimorbidity usually propose patient-centered interventions and consider an integrative multidisciplinary approach. Currently, little is known on the existence of such programs and on the role of family physicians (FPs)within these programs, in Switzerland. The objective of this study was to identify and describe current structured programs targeting chronic diseases or multi-morbidity in Switzerland. This may help in examining innovative approaches that are only developed locally but would deserve wider interest for further implementation. We conducted a telephone-based survey between June and November 2013 and contacted systematically key institutions, informants and stakeholders nationwide and in the 26 cantons...

The impact of balancing on problem hardness in a highly structured domain

Random problem distributions have played a key role in the study and design of algorithms for constraint satisfaction and Boolean satisfiability, as well as in ourunderstanding of problem hardness, beyond standard worst-case complexity. We consider random problem distributions from a highly structured problem domain that generalizes the Quasigroup Completion problem (QCP) and Quasigroup with Holes (QWH), a widely used domain that captures the structure underlying a range of real-world applications. Our problem domain is also a generalization of the well-known Sudoku puz- zle: we consider Sudoku instances of arbitrary order, with the additional generalization that the block regions can have rectangular shape, in addition to the standard square shape. We evaluate the computational hardness of Generalized Sudoku instances, for different parameter settings. Our experimental hardness results show that we can generate instances that are considerably harder than QCP/QWH instances of the same size. More interestingly, we show the impact of different balancing strategies on problem hardness. We also provide insights into backbone variables in Generalized Sudoku instances and how they correlate to problem hardness.

Ethnic sensitive substance abuse work : services for non-Finnish speaking clients in substance abuse treatment units in Finland today

The purpose of this study was to examine the current situation in substance abuse treatment units in Finland in taking non-Finnish speaking clients into consideration. The initiative for this research came from the Development of Alcohol and Drugs Intervention group at Stakes (National Research and Development Centre for Welfare and Health). Their aim was to gather information about the functioning and relevance of the quality assessment forms based on the quality recommendations for substance abuse work, filled in by substance abuse treatment units. The ethnic issue was chosen as the main approach in the study. The aim of this research was to answer the following questions: what is the readiness and competence in substance abuse treatment units in Finland to receive and encounter non-Finnish speaking clients, how is the quality of these services assessed and/or developed in the units, and what has been the role and functioning of the quality recommendations and quality assessment forms in working with non-Finnish speaking clients. The research methods used in the study were both quantitative and qualitative. The information concerning language services provided in the units was gathered from the quality assessment forms and basic information forms found in the database maintained by Stakes. The total amount of units found in the database was 267. In addition to that, semi-structured theme-interviews were carried out in four substance abuse treatment units in order to get a more deep understanding of how the services function in practice. The few number of non-Finnish speaking clients in the units may explain to a certain degree the results of the research. The results however showed that there is still space for improving the services. In the light of quality recommendations, the degree of language options provided in substance abuse treatment units in Finland today is low. Also the quantity of interpreter services provided in the units is scarce. There could also be unified guidelines specially tailored for substance abuse treatment units on how to work with ethnic minorities, as the knowledge is currently adopted from several different instances. The quality recommendations as well as quality assessment forms were valued and applied in the units appropriately and were also perceived to have an effect on the functioning, and quality, in the units.

Task complexity, the Cognition Hypothesis and second language learning and performance

In this paper we describe a taxonomy of task demands which distinguishes between Task Complexity, Task Condition and Task Difficulty. We then describe three theoretical claims and predictions of the Cognition Hypothesis (Robinson 2001, 2003b, 2005a) concerning the effects of task complexity on: (a) language production; (b) interaction and uptake of information available in the input to tasks; and (c) individual differences-task interactions. Finally we summarize the findings of the empirical studies in this special issue which all address one or more of these predictions and point to some directions for continuing, future research into the effects of task complexity on learning and performance.

Measurement of a Structured Backflow in an Open Small Channel Induced by Surface-Tension Gradients

We present experiments in which the laterally confined flow of a surfactant film driven by controlled surface tension gradients causes the subtended liquid layer to self-organize into an inner upstream microduct surrounded by the downstream flow. The anomalous interfacial flow profiles and the concomitant backflow are a result of the feedback between two-dimensional and three-dimensional microfluidics realized during flow in open microchannels. Bulk and surface particle image velocimetry data combined with an interfacial hydrodynamics model explain the dependence of the observed phenomena on channel geometry.

New genes for focal epilepsies with speech and language disorders.

The last 2 years have seen exciting advances in the genetics of Landau-Kleffner syndrome and related disorders, encompassed within the epilepsy-aphasia spectrum (EAS). The striking finding of mutations in the N-methyl-D-aspartate (NMDA) receptor subunit gene GRIN2A as the first monogenic cause in up to 20 % of patients with EAS suggests that excitatory glutamate receptors play a key role in these disorders. Patients with GRIN2A mutations have a recognizable speech and language phenotype that may assist with diagnosis. Other molecules involved in RNA binding and cell adhesion have been implicated in EAS; copy number variations are also found. The emerging picture highlights the overlap between the genetic determinants of EAS with speech and language disorders, intellectual disability, autism spectrum disorders and more complex developmental phenotypes.
