Analysis of the Establishment and Closure of the Ta Teh Institute in British Hong Kong during the Chinese Civil War
The Ta Teh Institute was a prominent and important higher learning institute that existed in Hong Kong during the period of the Chinese Civil War, after the Second World War. The institute was founded in October, 1946 and then forcefully banned by the Hong Kong Government in February, 1949. The institute was actually administered and controlled by the Chinese Communist Party. This paper aims to elucidate under what circumstances was the Ta Teh Institute established and closed. From a historical epistemological perspective, it is necessary to understand existing conditions through the lens of relevant past events. Thus, in this context, the reconstruction of epistemological history is applied to describe the actual situation. Although true and causally explained history can never be completely known, it can frequently be reasonably understood. Through performing a historical analysis, the results achieve a deeper understanding of the establishment and closure of the Ta Teh Institute during the Chinese Civil War
Multi-parameter Szemer\'{e}di-Trotter-type theorems and applications in finite fields
We prove some novel multi-parameter point-line incidence estimates in vector
spaces over finite fields. While these could be seen as special cases of
higher-dimensional incidence results, they outperform their more general
counterparts in those contexts. We go on to present a number of applications to
illustrate their use in combinatorial problems from geometry and number theory
EDSN: A First Demonstration of a Distributed System of Nanosatellites
Edison Demonstration of SmallSat Networks (EDSN) is the first demonstration of a distributed system of nano-scale satellites to use intersatellite communication while working towards common science and technology goals. This unique mission configuration poses key technological challenges, including multi-satellite deployment, close proximity flight, cross-satellite communications, and simplified and effective operations. Tackling these challenges has required extensive development on EDSNs guidance navigation and control (GNC) and flight software systems. Although use of COTS component is common to the CubeSat community, it is prudent to point out that utilization of these components enables EDSN to accomplish its objectives at relatively low cost ($12M) in comparison to current multi-satellite missions capable of cross-link communications. EDSN is on cost and schedule with flight unit shipment in August 2013. This paper aims to update the community of EDSN's progress since SRR and speaks to the approach EDSN has taken to resolve some of the main issues revolving around a distributed system of nano-scale satellites
Learning Reasoning Paths over Semantic Graphs for Video-grounded Dialogues
Compared to traditional visual question answering, video-grounded dialogues
require additional reasoning over dialogue context to answer questions in a
multi-turn setting. Previous approaches to video-grounded dialogues mostly use
dialogue context as a simple text input without modelling the inherent
information flows at the turn level. In this paper, we propose a novel
framework of Reasoning Paths in Dialogue Context (PDC). PDC model discovers
information flows among dialogue turns through a semantic graph constructed
based on lexical components in each question and answer. PDC model then learns
to predict reasoning paths over this semantic graph. Our path prediction model
predicts a path from the current turn through past dialogue turns that contain
additional visual cues to answer the current question. Our reasoning model
sequentially processes both visual and textual information through this
reasoning path and the propagated features are used to generate the answer. Our
experimental results demonstrate the effectiveness of our method and provide
additional insights on how models use semantic dependencies in a dialogue
context to retrieve visual cues.Comment: Accepted at ICLR (International Conference on Learning

Greener through gender: what climate mainstreaming can learn from gender mainstreaming
Addressing the urgent global climate crisis demands a rapid and meaningful expansion of “climate mainstreaming,” which refers to the integration of climate objectives in all aspects of development programs and policies. However, progress remains slow and uneven due to bottlenecks in policy and institutional change. Considering the parallel struggle recorded over decades to mainstream gender across the same policy arenas, a key question emerges: what can climate mainstreaming learn from gender mainstreaming? To answer this question, we review 57 policy, strategy, and guidance documents of United Nations agencies, all of which integrate these themes into food security and broader development programming. Our analysis identifies gaps in climate mainstreaming efforts and derives lessons from gender mainstreaming to bridge these gaps. It underscores the importance of adapting programmatic mainstreaming strategies in response to evolving contexts, for example, by simultaneously considering both mainstreaming and targeted interventions. Additionally, it highlights the need to adopt organizational climate mainstreaming and establish mechanisms for accountability. Finally, it emphasizes the urgency of embracing a climate justice lens; in practice, this involves prioritizing populations at greater risk of climate change impacts and actively engaging diverse perspectives in decision-making, particularly communities facing multiple forms of discrimination
