Assessing the language of 2 year-olds: From theory to practice

Early screening for language problems is a priority given the importance of language for success in school and interpersonal relationships. The paucity of reliable behavioral instruments for this age group prompted the development of a new touchscreen language screener for 2-year-olds that relies on language comprehension. Developmental literature guided selection of age-appropriate markers of language disorder risk that are culturally and dialectally neutral and could be reliably assessed. Items extend beyond products of linguistic knowledge (vocabulary and syntax) and tap the process by which children learn language, also known as fast mapping. After piloting an extensive set of items (139), two phases of testing with over 500 children aged 2; 0–2; 11 were conducted to choose the final 40-item set. Rasch analysis was used to select the best fitting and least redundant items. Norms were created based on 270 children. Sufficient test-retest reliability, Cronbach's alpha, and convergent validity with the MB-CDI and PPVT are reported. This quick behavioral measure of language capabilities could support research studies and facilitate the early detection of language problems.     

Gateway cities for transnational higher education? Doha,Dubai and Ras al-Khaimah as regional amplifiers in networks of the ‘global knowledge-based economy’

This paper investigates how the developmental ambitions of governments to attract university offshore campuses to Doha, Dubai and Ras al-Khaimah and these universities’ internationalization strategies affect the three cities’ positionalities. It links interdisciplinary literature on globally uneven geographies of higher education to geographical debates on the intermediating role of cities in regional and global economies. The paper conceptualizes the three cities as a triadic ensemble of gateways for transnational higher education (TNE), thereby contributing to further theorization of gateway cities. The paper shows that the three cities fulfil two crucial gateway functions. First, they connect internationalizing universities with particular student segments from their regional hinterlands seeking access to TNE. Second, they thereby amplify and disperse hegemonic regimes of the globalising knowledge-based economy in their regional hinterlands. While all three cities share similar functions and rationales, they also have distinct positionalities rooted in different strategies of the respective governments.

New tech,old exploitation: Gig economy,algorithmic control and migrant labour

Digital platforms are the newest technological wave that is reshaping and reconfiguring the economic and labour landscape. Digital platforms often known as the gig economy are increasingly adopting app-based models to connect consumers with workers to complete their on-demand tasks. However, on-demand platforms continue to rely on the unequal division of labour and the precarious nature of the work to create labour markets that can respond accordingly to the increase in service provision. This review highlights two main themes that have emerged within the on-demand gig economy in the current literature—mythical autonomy and algorithmic control and misclassification of labour and the complexity of migrant workers in navigating this space. Finally, this review calls for further research into the inside/outside dichotomy of migrant labour within the gig economy and their experiences of labour exploitation through app-based digital platforms.
