Mainland Chinese undergraduates’ academic socialisation in Hong Kong

Research has confirmed that supportive social networks and associated resources play a critical role in the adaptation of migrating international students to host communities. Access to such social networks and resources requires migrating students to invest in and make efforts at academic socialisation, as mediated by various social processes. This article reports on an examination of 26 mainland Chinese undergraduates’ experiences of academic socialisation in a major university in Hong Kong. Drawing on these students’ experiential accounts, the inquiry identified a variety of linguistic, sociocultural and ideological challenges that undermine the participants’ academic socialisation with local students in Hong Kong. It also recorded strategic efforts undertaken by the participants to align themselves with their local counterparts linguistically and socially. These efforts helped some participants overcome various challenges in academic socialisation but most of them chose to socialise with other mainland Chinese students and further alienate themselves from local students. In light of shifting contextual conditions, it may be increasingly difficult for migrant students to construct a cohesive university community with local students. Therefore, institutions need to invest more in facilitating and supporting different groups of students’ engagement with each other in achieving mutual understanding through shared activities.postprin

The theory of the exponential differential equations of semiabelian varieties

The complete first order theories of the exponential differential equations of semiabelian varieties are given. It is shown that these theories also arises from an amalgamation-with-predimension construction in the style of Hrushovski. The theory includes necessary and sufficient conditions for a system of equations to have a solution. The necessary condition generalizes Ax's differential fields version of Schanuel's conjecture to semiabelian varieties. There is a purely algebraic corollary, the "Weak CIT" for semiabelian varieties, which concerns the intersections of algebraic subgroups with algebraic varieties.Comment: 53 pages; v3: Substantial changes, including a completely new introductio

The Wonders of the Galapagos Islands: Experiential Learning is Deep Learning

Experiential learning is one way of creating deep understanding of subject matter, as well as developing a passion for the field. I have been engaged in leading extended field experiences with students for almost 20 years to ‘immerse’ students in the natural world. In March 2020, Dr. Krumins and I led a group of graduate and undergraduate students to Ecuador to explore and learn about the incredible wildlife and the enduring legacy of revolutionary ideas that this region has generated. Our time in the Galapagos, while short, spanned centuries of scientific thought and millions of years of geologic history. The Galapagos Islands have shaped our understanding of chemosynthesis and the origins of life on Earth and that radical idea of Evolution. Join me on an immersive journey

Frailty criteria among older people living in the community. An update

Indexación: Web of Science; Scielo; Scopus.Frailty is an important concept in aging research and care. Awareness of frailty signs allows healthcare workers to identify older adults at risk and design interventions to prevent their functional decline, therefore preventing adverse health outcomes. This literature review allows to identify predictors of frailty considering its physical, psychological and social domains. From the evidence found, it is possible to formulate a profile of fragile older people. Finally, future research should focus on the description of psychological and social fragility profiles, on the detection of persons likely to be fragile and finally to define precise instruments to detect fragile people, which should become the gold standards in future research.http://ref.scielo.org/ykbdx

Constructing level-2 phylogenetic networks from triplets

Jansson and Sung showed that, given a dense set of input triplets T (representing hypotheses about the local evolutionary relationships of triplets of species), it is possible to determine in polynomial time whether there exists a level-1 network consistent with T, and if so to construct such a network. They also showed that, unlike in the case of trees (i.e. level-0 networks), the problem becomes NP-hard when the input is non-dense. Here we further extend this work by showing that, when the set of input triplets is dense, the problem is even polynomial-time solvable for the construction of level-2 networks. This shows that, assuming density, it is tractable to construct plausible evolutionary histories from input triplets even when such histories are heavily non-tree like. This further strengthens the case for the use of triplet-based methods in the construction of phylogenetic networks. We also show that, in the non-dense case, the level-2 problem remains NP-hard
