Challenges in teaching English to young learners:global perspectives and local realities

Drawing on data from a recent research international research project, this article focuses on the challenges faced by teachers of English to young learners against the backdrop of the global rise of English. A mixed-methods approach was used to obtain the data, including a survey, which was completed by 4,459 teachers worldwide, and case studies, including observations and interviews with teachers, in five different primary schools in five different countries. A number of challenges emerged as affecting large numbers of teachers in different educational contexts, namely, teaching speaking, motivation, differentiating learning, teaching large classes, discipline, teaching writing, and teaching grammar. Importantly, some of these challenges have not been highlighted in the literature on young learner teaching to date. Other challenges are more localised, such as developing teachers' English competence. The article argues that teacher education should focus less on introducing teachers to general approaches to English language teaching and more on supporting teachers to meet the challenges that they have identified.

Identification of DNA-binding proteins by incorporating evolutionary information into pseudo amino acid composition via the top-n-gram approach

DNA-binding proteins are crucial for various cellular processes and hence have become an important target for both basic research and drug development. With the avalanche of protein sequences generated in the postgenomic age, it is highly desired to establish an automated method for rapidly and accurately identifying DNA-binding proteins based on their sequence information alone. Owing to the fact that all biological species have developed beginning from a very limited number of ancestral species, it is important to take into account the evolutionary information in developing such a high-throughput tool. In view of this, a new predictor was proposed by incorporating the evolutionary information into the general form of pseudo amino acid composition via the top-n-gram approach. It was observed by comparing the new predictor with the existing methods via both jackknife test and independent data-set test that the new predictor outperformed its counterparts. It is anticipated that the new predictor may become a useful vehicle for identifying DNA-binding proteins. It has not escaped our notice that the novel approach to extract evolutionary information into the formulation of statistical samples can be used to identify many other protein attributes as well.

The big 4 in Bangladesh:caught between the global and the local

Purpose- This article explores the work practices of Big 4 firms in Bangladesh with the aim of exploring the extent to which Global Professional Service Firms can be thought of as being genuinely ‘global’. Methodology/Approach- Interviews were undertaken with the vast majority of Big 4 partners in Bangladesh. These interviews explored a number of themes related to the professional service work context in Bangladesh and the relationship between local and global firms. Findings- The central finding of this paper is that although the Big 4 have a long-established presence in Bangladesh, local societal factors heavily influence the realities of work for accountants there. In most cases the Big 4 firms establish correspondent firms (instead of full member firms) in Bangladesh and tend to offer restricted service lines. Additionally, the paper identifies professional, commercial and cultural barriers to greater Big 4 involvement in the local market. Conceptually, the chief contribution of this paper is to explore how the effects of globalising capitalism and standardised ‘best practices’ in global professional service work are mediated through the societal effects of Bangladeshi society, resulting in the Big 4 having only a tentative presence in the Bangladeshi market. Research implications- The findings cast doubt on the extent to which self-styled Global Professional Service firms are truly ‘global’ in nature. Future work examining the Big 4, or accounting more generally, in the context of globalization, would do well to pay greater attention to the experience of professionals in emerging markets. Originality/Value- Whilst there has been much work looking at accounting and accountants in the context of globalization, this work has tended to privilege ‘core’ western empirical settings. Very little is known about Professional Service Firms in ‘peripheral’ or emerging markets. Furthermore, this study extends the application of the System, Society and Dominance framework by mapping the interactions and dynamics of these three sources of influence in the setting of PSFs.

Implementation of pseudo J-integral based Paris’ law for fatigue cracking in asphalt mixtures and pavements

Pavement analysis and design for fatigue cracking involves a number of practical problems like material assessment/screening and performance prediction. A mechanics-aided method can answer these questions with satisfactory accuracy in a convenient way when it is appropriately implemented. This paper presents two techniques to implement the pseudo J-integral based Paris’ law to evaluate and predict fatigue cracking in asphalt mixtures and pavements. The first technique, quasi-elastic simulation, provides a rational and appropriate reference modulus for the pseudo analysis (i.e., viscoelastic to elastic conversion) by making use of the widely used material property: dynamic modulus. The physical significance of the quasi-elastic simulation is clarified. Introduction of this technique facilitates the implementation of the fracture mechanics models as well as continuum damage mechanics models to characterize fatigue cracking in asphalt pavements. The second technique about modeling fracture coefficients of the pseudo J-integral based Paris’ law simplifies the prediction of fatigue cracking without performing fatigue tests. The developed prediction models for the fracture coefficients rely on readily available mixture design properties that directly affect the fatigue performance, including the relaxation modulus, air void content, asphalt binder content, and aggregate gradation. Sufficient data are collected to develop such prediction models and the R2 values are around 0.9. The presented case studies serve as examples to illustrate how the pseudo J-integral based Paris’ law predicts fatigue resistance of asphalt mixtures and assesses fatigue performance of asphalt pavements. Future applications include the estimation of fatigue life of asphalt mixtures/pavements through a distinct criterion that defines fatigue failure by its physical significance.

Reforming the Swedish employment-related social security system:activation, administrative modernization and strengthening local autonomy

The Swedish system of social security has often been regarded as comprehensive and comprehensive and inclusive. During major reforms in the 1990s and 2000s, it has maintained its essential character as a popular and well-endowed provider of social security and stability. Employment-related benefits are generous in financial terms, but come with the need for recipients to remain actively engaged in the economic or educational field. However, Sweden’s geographical and demographic diversity made it necessary to increase the role of local authorities in implementing active labour market policies. This article tracks these developments since the mid-1990s, both with regard to changing the benefits system and with regard to changing local government involvement. It argues that backed by broad political support, the Swedish system has achieved the necessary modernisation and adaptation to remain a viable alternative to more neo-liberal welfare retrenchment projects conducted in other European countries.
