The manifestations of universality and cultural specificity in national curriculum policy frameworks: negotiations for culturally reflective practice in early childhood education

This paper presents findings from a review of 19 national curriculum policy frameworks (NCPFs) across the globe and discusses dominant and culturally specific discourses that shape early childhood education (ECE). We combine two frameworks of developmental universality and specificity and culturally contextualised pedagogy to explore whether and how NCPFs are venues where culturally reflective practice is negotiated. Culturally reflective practice embraces minimum, globally universal standards of children’s rights and evidence-based practice, meanwhile critically reflects on the dominance of global and local discourses that impede a glocalised interpretation of quality in ECE. The paper argues that culturally reflective policy and practice is an alternative framework to cultural appropriateness/relevance in ECE

Linear Depth QFT over IBM Heavy-hex Architecture

Compiling a given quantum algorithm into a target hardware architecture is a challenging optimization problem. The compiler must take into consideration the coupling graph of physical qubits and the gate operation dependencies. The existing noise in hardware architectures requires the compilation to use as few running cycles as possible. Existing approaches include using SAT solver or heuristics to complete the mapping but these may cause the issue of either long compilation time (e.g., timeout after hours) or suboptimal compilation results in terms of running cycles (e.g., exponentially increasing number of total cycles). In this paper, we propose an efficient mapping approach for Quantum Fourier Transformation (QFT) circuits over the existing IBM heavy-hex architecture. Such proposal first of all turns the architecture into a structure consisting of a straight line with dangling qubits, and then do the mapping over this generated structure recursively. The calculation shows that there is a linear depth upper bound for the time complexity of these structures and for a special case where there is 1 dangling qubit in every 5 qubits, the time complexity is 5N+O(1). All these results are better than state of the art methods

RetGen: A Joint framework for Retrieval and Grounded Text Generation Modeling

Recent advances in large-scale pre-training such as GPT-3 allow seemingly high quality text to be generated from a given prompt. However, such generation systems often suffer from problems of hallucinated facts, and are not inherently designed to incorporate useful external information. Grounded generation models appear to offer remedies, but their training typically relies on rarely-available parallel data where information-relevant documents are provided for context. We propose a framework that alleviates this data constraint by jointly training a grounded generator and document retriever on the language model signal. The model learns to reward retrieval of the documents with the highest utility in generation, and attentively combines them using a Mixture-of-Experts (MoE) ensemble to generate follow-on text. We demonstrate that both generator and retriever can take advantage of this joint training and work synergistically to produce more informative and relevant text in both prose and dialogue generation.Comment: accepted by AAAI-22, camera ready versio
