- The present study assesses linguistic and geographic diversity in selected outlets of SLA and multilingualism research. Specifically, we examine over 2,000 articles published in specialized top-tier journals, recording the languages under study and their acquisition order, author affiliations, the country in which the research was conducted, and citations. In the sample, there were 183 unique languages and 174 unique pairings, corresponding to 3 per cent of the world’s 7,000 languages and less than 0.001 per cent of 24.5 million possible language combinations. English was overwhelmingly the most common language, followed by Spanish and Mandarin Chinese. North America and Western Europe were both the main producers of knowledge and the main sites for research on multilingualism in the sample. Crucially, the regions with the highest levels of linguistic diversity and societal multilingualism (typically the Global South) were only marginally represented. The findings also show that studies on English and northern Anglophone settings were likely to elicit more citations than studies on other languages and settings, and that less studied languages were included more frequently in article titles.

Motion event categorisation in a nativised variety of South African English

- The present study seeks to expand the current focus on acquisition situations in linguistic relativity research by exploring the effects of nativisation (the process by which a L2 is acquired as a L1) on language-specific cognitive behaviour. Categorisation preferences of goal-oriented motion events were investigated in South African speakers who learnt English as a L1 from caregivers who spoke English as a L2 and Afrikaans as a L1. The aim of the study was to establish whether the categorisation patterns found in the nativised English variety: (1) resemble patterns of L2 speakers of English with Afrikaans as a L1, (2) resemble patterns of L1 English speakers of a non-nativised English variety and (3) do not pattern with either of the above, but instead exhibit a distinct behaviour. It was found that simultaneous, functional bilinguals (Afrikaans and nativised English) patterned with L1 Afrikaans speakers, but the extent to which they did so was modulated by their frequency of use of Afrikaans. Functionally monolingual speakers of nativised English, on the other hand, patterned with L1 speakers of British English. This suggests that bilingualism, rather than nativisation, was a reliable predictor of event categorisation preferences.

- Research on the relationship between grammatical aspect and motion event construal has posited that speakers of non-aspect languages are more prone to encoding event endpoints than are speakers of aspect languages (e. g., von Stutterheim and Carroll 2011). In the present study, we test this hypothesis by extending this line of inquiry to Afrikaans, a non-aspect language which is previously unexplored in this regard. Motion endpoint behavior among Afrikaans speakers was measured by means of a linguistic retelling task and a non-linguistic similarity judgment task, and then compared with the behavior of speakers of a non-aspect language (Swedish) and speakers of an aspect language (English). Results showed the Afrikaans speakers' endpoint patterns aligned with Swedish patterns, but were significantly different from English patterns. It was also found that the variation among the Afrikaans speakers could be partially explained by taking into account their frequency of use of English, such that those who used English more frequently exhibited an endpoint behavior that was more similar to English speakers. The current study thus lends further support to the hypothesis that speakers of different languages attend differently to event endpoints as a function of the grammatical category of aspect.

- A novel off-lattice three-dimensional coarse-grained Monte Carlo model is developed to study engineered nanoparticle (ENP) behavior in porous media. Based on individual particle tracking and on the assumption that different physicochemical processes may occur with different probabilities, our model is used to independently evaluate the influence of homoaggregation, attachment and detachment processes on ENP transport and retention inside porous media made of colloidal collectors. The possibility of straining, i.e. trapping of ENPs or aggregates that are too large to pass pore necks, is also included in the model. The overall probability of ENP retention as a function of the above mentioned processes is quantified using functional tests in the form of a alpha(global)(t(ref)) retention parameter. High alpha(global)(t(ref)) values were obtained for moderate probabilities of homoaggregation between ENPs (alpha(ENP-ENP)) and very small probabilities of attachment between ENPs and collectors (alpha(att)), thus indicating the important role of homoaggregation and attachment in ENP retention. Moreover, attaching ENPs and large aggregates was found to cause pore neck enclosure and thus largely contributed to the straining of unbound ENPs. An analysis of depth distribution of retained ENPs revealed that, depending on the dominating conditions, the number of ENPs was decreasing monotonously or exponentially with depth. The introduction of the ENP detachment probability (alpha(det)) from collectors resulted in an increased ENP occurrence at the porous media matrix outlet. It was also found that different sets of alpha(det) and alpha(att) values, reflecting different ENPs and collector physicochemical properties and inter-particle forces, lead to identical alpha(global)(t(ref)) values. This constitutes an important outcome indicating that alpha(global)(t(ref)) values determined from functional tests are not mechanistic but operationally defined parameters and thus cannot be deemed predictive beyond these tests.
