Navigating and negotiating borders: Western pre-service teachers’ experiences of teaching science in a non-western setting

The subculture of science has ‘borders’ that many find difficult to negotiate. These borders become more complex the further understandings of science are from traditional western perspectives. This paper therefore examines the experiences of two western pre-service teachers’ teaching science in a non-western context--the Cook Islands. The lens of ‘border crossing’ has been used to make sense of these teachers’ learning to teach experiences as it provides insights into the ways in which the participants negotiated such crossings over time. This research highlights the importance of recognising the positive interactions and potential for diverse experiences within a cultural context

Love thy neighbour? Coronavirus politics and their impact on EU freedoms and rule of law in the Schengen Area. CEPS Paper in Liberty and Security in Europe No. 2020-04, April 2020

Restrictions on international and intra-EU traffic of persons have been at the heart of the political responses to the coronavirus pandemic. Border controls and suspensions of entry and exist have been presented as key policy priorities to prevent the spread of the virus in the EU. These measures pose however fundamental questions as to the raison d’être of the Union, and the foundations of the Single Market, the Schengen system and European citizenship. They are also profoundly intrusive regarding the fundamental rights of individuals and in many cases derogate domestic and EU rule of law checks and balances over executive decisions. This Paper examines the legality of cross-border mobility restrictions introduced in the name of COVID-19. It provides an in-depth typology and comprehensive assessment of measures including the reintroduction of internal border controls, restrictions of specific international traffic modes and intra-EU and international ‘travel bans’. Many of these have been adopted in combination with declarations of a ‘state of emergency’

Categorizations of the interface of evolution and religion

This piece responds to the article by Arif Rachmatullah, Soonhye Park, and Minsu Ha “Crossing borders between science and religion: Muslim Indonesian biology teachers\u27 perceptions of teaching the theory of evolution,” in which the authors are among the first researchers to explore the views of Indonesian science teachers regarding evolution instruction. This new context is important for furthering a global perspective on evolution education. However, the authors use preexisting taxonomies for their analyses that were developed in studies executed in mostly Christian contexts. In this response, we argue that investigations into new geographical and religious milieus, such as the teachers in the study by Rachmatullah and colleagues, could instead be used to develop more attuned categorizations for the burgeoning research area of the interaction of Islam, Judaism, and other traditions with evolution. We reflect upon experiences from our own work in studying Jewish and Muslim views of evolution, as well as on alternative taxonomies developed regarding Islam and evolution; we close with a brief rationale for a current initiative to create a researchers’ network for those who study the interface of science, religion, and society in the Middle East and North Africa

Asteroid flux towards circumprimary habitable zones in binary star systems: I. Statistical Overview

So far, multiple stellar systems harbor more than 130 extra solar planets. Dynamical simulations show that the outcome of planetary formation process can lead to various planetary architecture (i.e. location, size, mass and water content) when the star system is single or double. In the late phase of planetary formation, when embryo-sized objects dominate the inner region of the system, asteroids are also present and can provide additional material for objects inside the habitable zone (hereafter HZ). In this study, we make a comparison of several binary star systems and their efficiency to move icy asteroids from beyond the snow-line into orbits crossing the HZ. We modeled a belt of 10000 asteroids (remnants from the late phase of planetary formation process) beyond the snow-line. The planetesimals are placed randomly around the primary star and move under the gravitational influence of the two stars and a gas giant. As the planetesimals do not interact with each other, we divided the belt into 100 subrings which were separately integrated. In this statistical study, several double star configurations with a G-type star as primary are investigated. Our results show that small bodies also participate in bearing a non-negligible amount of water to the HZ. The proximity of a companion moving on an eccentric orbit increases the flux of asteroids to the HZ, which could result into a more efficient water transport on a short timescale, causing a heavy bombardment. In contrast to asteroids moving under the gravitational perturbations of one G-type star and a gas giant, we show that the presence of a companion star can not only favor a faster depletion of our disk of planetesimals but can also bring 4 -- 5 times more water into the whole HZ.Comment: Accepted for publication in A&

Crossing borders . . . shifting sands: An investigation of Chinese students’ study experiences in the UK and China

In the current landscape of higher education in the UK, international students play a key role. It is an environment in which they not only cross borders physically but also transition through various identities as they develop their professional and linguistic confidence and skills to fully access and contribute to their programme of study and beyond. The aim of this paper is to outline the results of an empirical investigation into Chinese students’ perceptions of their study experiences in the context of student mobility and English-medium instruction in higher education. It reports on a study of two groups of Chinese students – one group studying in an English-speaking environment, the other in their home country where instruction is delivered through the medium of English. Semi-structured focus group interviews were conducted at each site which focused on the transition of “crossing borders” for educational purposes. The data was analysed using thematic analysis (Clarke & Braun, 2016). The main finding was that both groups experienced remarkably similar learning issues, despite being located in very different learning environments and crossing different types of borders

Quantum phase transitions in the Fermi-Bose Hubbard model

We propose a multi-band Fermi-Bose Hubbard model with on-site fermion-boson conversion and general filling factor in three dimensions. Such a Hamiltonian models an atomic Fermi gas trapped in a lattice potential and subject to a Feshbach resonance. We solve this model in the two state approximation for paired fermions at zero temperature. The problem then maps onto a coupled Heisenberg spin model. In the limit of large positive and negative detuning, the quantum phase transitions in the Bose Hubbard and Paired-Fermi Hubbard models are correctly reproduced. Near resonance, the Mott states are given by a superposition of the paired-fermion and boson fields and the Mott-superfluid borders go through an avoided crossing in the phase diagram.Comment: 4 pages, 3 figure
