Heritage preservation and sociocultural adaptation among South Asian immigrants in Hong Kong: A perspective through dynamic family language policy
Through the lens of family language policy (FLP), this qualitative study examines how South Asian immigrant families in Hong Kong navigate the dual imperatives of preserving their cultural and linguistic heritage while adapting to the sociocultural demands of the host society. Drawing on semi-structured individual interviews and recordings of their daily conversations, the findings reveal that FLP is a dynamic and adaptive framework that enables …
School students’ aspirations for STEM careers: The influence of self-concept, parental expectations, career outcome expectations, and perceptions of STEM professionals
This study examined the processes that contributed to students’ aspirations for STEM careers and unpacked the relationships between students’ self-concept in science and mathematics learning, perceived parental expectations, perceptions of STEM professionals, career outcome expectations and STEM career aspirations. Structural equation modelling was used to analyse quantitative survey data of 2,477 primary and secondary school students studying in…

A Systematic Review of Family Language Policy Studies From 2008 to 2024
As an interdisciplinary field involving language policy, language socialization, and literacy studies, family language policy (FLP) has received growing research attention. This study synthesized the major theoretical perspectives and methodological characteristics of FLP empirical research and the range of research foci and highlighted possible avenues for future research. An in‐depth analysis combining quantitative and qualitative approaches wa…
Diversified cropping systems with limited carbon accrual but increased nitrogen supply
A Review of Digital Technology in Informal Education and Its Role in Educational Equity
Digital technologies have profoundly transformed the landscape of education, enhancing learning approaches while raising concerns about digital equity. This review pays particular attention to informal education settings (e.g., public libraries, museums, and telecentres) and examines the application of digital technologies in these settings and their role in educational equity. Specifically, it focuses on the diverse Guangdong–Hong Kong–Macao Gre…
Artificial Intelligence for Language Learning: A Systematic Review of its Design, Theoretical Foundations, Implementation, and Impact
Although the use of AI technologies (e.g., chatbots and automated writing evaluations (AWE)) has gained considerable attention in language learning fields in recent years, how AI technologies have been designed and implemented in language learning education, as well as their effectiveness, is understudied. The current study thus seeks to provide a systematic review of the empirical evidence on the research status and impact of AI technologies in …
Bittersweet English private tutoring: Chinese parents’ and children’s emotions in negotiating family language policies
Inquiry-based science teaching in English Medium Instruction science secondary classrooms: Teachers’ understanding and perceptions
This mixed-method study, employing inquiry-based science teaching theory, delves into the interaction of English Medium Instruction (EMI) and scientific inquiry by investigating science teachers’ understanding and perceptions of conducting inquiry-based science activities in EMI classrooms. Drawing on a questionnaire of 166 EMI science teachers and in-depth individual interviews with five of them, the findings suggest that these EMI science teach…
Translanguaging in scientific practices: A study of high school teachers in English Medium Instruction inquiry-based science classrooms
English as a Medium of Instruction (EMI) is being used to teach academic subjects in international programmes in China to meet the growing number of Chinese students’ need to study abroad. Through the lens of inquiry-based science teaching, this study examined how the four EMI science teachers of an international programme at a private high school employed translanguaging in scientific practices such as identifying variables and formulating hypot…
Exploring the problems of learning science in the English medium: A study on high school students’ perceptions and attitudes in China
English is being used as a medium of instruction (EMI) for delivering science lessons in China. This study investigated Chinese high school international programme students’ perceptions of and attitudes towards EMI, particularly about their perceived difficulties and support in learning. A questionnaire with Likert-type items, student group interviews, and individual teacher interviews were used in the study. Quantitative data were analysed using…
China’s forestation on marginal land was less efficient in carbon sequestration compared with non-marginal land
Riverine nitrogen footprint of agriculture in the Mississippi–Atchafalaya River Basin: Do we trade water quality for crop production
Increasing food and biofuel demands have led to the cascading effects from cropland expansions, raised fertilizer use, to increased riverine nitrogen (N) loads. However, little is known about the current trade-off between riverine N pollution and crop production due to the lack of predictive understanding of ecological processes across the land-aquatic continuum. Here, we propose a riverine N footprint (RNF) concept to quantify how N loads change…
Impacts of tillage practices on soil carbon stocks in the US corn-soybean cropping system during 1998 to 2016
Tillage alters the thermal and wetness conditions in soil, which facilitates soil organic matter oxidation and water transportation, leading to rapid depletion of soil carbon (C). Little is known about tillage intensity change (TIC) and its impacts in the US corn-soybean rotation system over the past two decades. Using time-series tillage maps developed from a private survey and a process-based land ecosystem model, here we examined how tillage i…
Increasing carbon footprint of grain crop production in the US Western Corn Belt
Global agriculture is challenged to increase soil carbon sequestration and reduce greenhouse gas emissions while providing products for an increasing population. Growing crop production could be achieved through higher yield per hectare (i.e. intensive farming) or more hectares (extensive farming),which however, have different ecological and environmental consequences.Multiple lines of evidence indicate that expanding cropland for additional prod…
Optimizing resource use efficiencies in the food–energy–water nexus for sustainable agriculture: From conceptual model to decision support system
Global gross primary productivity and water use efficiency changes under drought stress
Drought can affect the structure, composition and function of terrestrial ecosystems, yet drought impacts and post-drought recovery potentials of different land cover types have not been extensively studied at a global scale. We evaluated drought impacts on gross primary productivity (GPP), evapotranspiration (ET), and water use efficiency (WUE) of different global terrestrial ecosystems, as well as the drought-resilience of each ecosystem type d…
Global land carbon sink response to temperature and precipitation varies with Enso phase
Climate variability associated with the El Niño-Southern Oscillation (ENSO) and its consequent impacts on land carbon sink interannual variability have been used as a basis for investigating carbon cycle responses to climate variability more broadly, and to inform the sensitivity of the tropical carbon budget to climate change. Past studies have presented opposing views about whether temperature or precipitation is the primary factor driving the …
Disentangling climatic and anthropogenic controls on global terrestrial evapotranspiration trends
We examined natural and anthropogenic controls on terrestrial evapotranspiration (ET) changes from 1982 to 2010 using multiple estimates from remote sensing-based datasets and process-oriented land surface models. A significant increasing trend of ET in each hemisphere was consistently revealed by observationally-constrained data and multi-model ensembles that considered historic natural and anthropogenic drivers. The climate impacts were simulat…
