Calls for multilingual pedagogies have reached early childhood education and some programmes have been implemented in Europe. However, their focus frequently remains on the majority language and home languages are given little space. For multilingual programmes to be inclusive and empowering, professionals need to break with monolingual practices based on monolingual ideologies. The resource-oriented pedagogy of translanguaging which challenges hegemonic practices, is one way in which professionals can give space to all languages, leverage children’s resources and contribute to their development. The present chapter presents the findings of a professional development on multilingual pedagogies in Luxembourg. Data stem from observations, video-recorded activities and interviews with four practitioners, two working in a formal education setting and two in a non-formal one. The findings show that the practitioners developed a positive stance towards translanguaging and multilingual education, learned to design a child-centred and holistic multilingual learning environment and used languages flexibly, deploying translation, code-switching and translanguaging. This dynamic language use facilitated communication, participation, language learning and well-being. There were differences between the practitioners’ flexible language use. The professionals in the school did not use pair talk, made less use of code-switching and used languages more strategically and responsibly than the caregivers in the crèche. [less ▲]

We present a novel framework for multi-group multicast precoding in the presence of three types of wireless users which are distributed among various multicast groups. A multi-antenna transmitter conveys information and/or energy to the groups of corresponding receivers using more than one multicast streams. The information specific users have conventional receiver architectures to process data, energy harvesting users collect energy using the non-linear energy harvesting module and each of the joint information decoding and energy harvesting capable user is assumed to employ the separated architecture with disparate non-linear energy harvesting and conventional information decoding units. In this context, we formulate and analyze the problem of total transmit power minimization for optimal precoder design subjected to minimum signal-to-interference-and-noise ratio and harvested energy demands at the respective users under three different scenarios. This problem is solved via semi-definite relaxation and the advantages of employing separate information and energy precoders are shown over joint and per-user information and energy precoder designs. Simulation results illustrate the benefits of proposed framework under several operating conditions and parameter values. [less ▲]

For any integer $q\geq 2$ we provide a formula to express indefinite sums of a sequence $(f(n))_{n\geq 0}$ weighted by $q$-periodic sequences in terms of indefinite sums of sequences $(f(qn+p))_{n\geq 0}$, where $p\in\{0,\ldots,q-1\}$. When explicit expressions for the latter sums are available, this formula immediately provides explicit expressions for the former sums. We also illustrate this formula through some examples.

This paper reports on the use of bracketed text in a large corpus of student writing. The function of bracketing has been neglected in academic writing research and coursebooks. Yet it is closely related to important text construction issues such as information packaging, coherence, clarity, conciseness, intertextual framing and sourcing. With a view to informing academic writing description and instruction, we examined the relationship between bracketed text and its cotext in a wide variety of disciplines and assignment genres. The relationships are described using an adaptation of Halliday and Matthiessen’s (2014) logico-semantic framework of clausal relationships. To better understand and teach the use of this information packaging feature, we studied the relationship between bracketed text and its cotext in the British Academic Written English (BAWE) corpus of high-graded student assignments. Using Sketch Engine and corpus query language, we extracted a random sample of 2000 instances of bracketing in running text only. This subcorpus is composed of 500 instances from each of the four main disciplinary groupings (Arts and Humanities, Life Sciences, Physical Sciences, Social Sciences) and contains instances from most of the BAWE assignment genres. The concordances were imported into a database table in FileMaker Pro. This database programme facilitates coding by limiting choices depending on previous selections and thus guiding the coder through the analytical steps. For the analysis of the data, it offers flexibility for grouping records and aggregating results on different levels. The logico-semantic framework used in systemic functional linguistics to classify the relationships between clauses (Halliday & Matthiessen, 2014) served as our starting point to classify the relationships between bracketed text and cotext. This framework distinguishes two fundamental logico-semantic relationships: expansion, which ‘relates phenomena as being of the same order of experience’, and projection, which ‘relates phenomena of one order of experience (the processes of saying and thinking) to phenomena of a higher order (semiotic phenomena – what people say and think)’ (p. 443). The latter contains three subtypes: elaboration (‘one clause elaborates on the meaning of another by further specifying or describing it’) (p. 461), enhancement (‘one clause (or subcomplex) enhances the meaning of another by qualifying it) (p. 476) and extension (‘one clause extends the meaning of another by adding something new to it’) (p. 471). This framework was refined and expanded through several stages of interrating and discussion in order to reflect our findings. We first analysed a random sample of 1000 instances from the whole BAWE corpus. With the resulting adapted classificatory framework we next independently analysed a quarter of our subcorpus of 2000 concordances. This led to further refinement of the framework and classificatory criteria. Finally, we each analyzed a different set of concordances from the disciplinary groupings. Disciplinary informants were consulted where needed. Our analysis revealed four major logico-semantic relationships between the bracketed text and cotext: in addition to Halliday & Matthiessen’s (2014) projection (1) and expansion (elaboration (2), enhancement (3, 4), extension (5)), we identified bracketed text functioning as intratextual reference (6) and code (7). The few instances that could not be confidently classified were assigned to a ‘hard to classify’ category. (1) However the anticipated number of children per woman in Europe and the USA is still near or above two (Bongaarts, 1999), showing that many are still having children. (2) Many of these injures are healed fractures and breaks occurring around the torso (upper body). (3) It is dated to the reign of Nectanebo II (360-343 BC). (4) Acetanilide (4.78g, 35.4 mmol) was dissolved in cold, glacial acetic acid (25ml, 437.1 mmol) (5) Parmenides decision to include a cosmology that he has already (apparently) proved to be flawed is an interesting one to say the least. (6) This is called circular polarization (figure 5) and is the natural state of white light. (7) Stronger field ligands such as (PPh 3) and (NCS) increase the splitting. Projection was –perhaps not surprisingly- the most common relationship by far, although markedly less frequent in the Physical Sciences. Expansion was mainly achieved through elaboration, with restatements (2) and abbreviations predominating. Enhancement relationships were mostly temporal locations (3) or measurements (4). Extension was relatively rare (5). Intratextual references (6) took various forms, such as figures, appendices, equations, and line numbers for quoted text. Bracketed code was a marked feature of the Physical Sciences, occurring in formulae and enclosing symbols or abbreviations (7). Overall, students’ use of bracketed text appeared to reflect disciplinary conventions and reflected the genre goals of assignments by demonstrating knowledge, understanding and appropriate source use. Contrary to expectations, instances where the bracketed text seemed superfluous or adversely affected coherence were rare. We conclude by discussing what these findings mean for academic writing instruction. Reference Halliday, M. A. K., & Matthiessen, C. M. I. M. (2014).

On 8 January 2019, an action was brought before the Court of Justice of the European Union (hereafter CJEU) by an environmental law charity, ClientEarth (hereafter applicant) against a multilateral development bank (hereafter MDB) and European institution, the European Investment Bank (hereafter EIB). The case concerns the financing by the bank of a biomass energy generating project in Northern Spain – Galicia -, of the cost of 60 million euros, followed by the bank’s refusal to refine its decision to finance the aforementioned investment, regardless the applicant’s request for an internal review of this decision on April 2018. The applicant bases the request for an internal review on alleged ‘errors in the assessment of the financing combined with the provision of minimal information regarding the funding decision’. The main claim brought by the applicant involves the annulment of EIB’s refusal to conduct an internal review and subject its decision to scrutiny, as requested under Article 10 of the Aarhus Regulation (hereafter Regulation), bringing into discussion implementation issues of both International and European law.

We present a stochastic approach combining Bayesian Inference (BI) with homogenization theories in order to identify, on the one hand, the parameters inherent to the model assumptions and, on the other hand, the composite material constituents behaviors, including their variability. In particular, we characterize the model parameters of a Mean-Field Homogenization (MFH) model and the elastic matrix behavior, including the inherent dispersion in its Young's modulus, of non-aligned Short Fibers Reinforced Polymer (SFRP) composites. The inference is achieved by considering as observations experimental tests conducted at the SFRP composite coupons level. The inferred model and material law parameters can in turn be used in Mean-Field Homogenization (MFH)-based multi-scale simulations and can predict the confidence range of the composite material responses.
