Prosocial Behaviour and Diffusion of Responsibility: Helping Friends and Family over Strangers

This paper was originally written for Dr. V. Gordon Rose’s Psychology 300 course Critical Analysis of Issues in Psychology. The assignment asked students to write a thesis-based research paper on any topic pertaining to the course material; a lecture on prosocial giving served as the springboard for this writing.

Common graphs with arbitrary connectivity and chromatic number

A graph $H$ is common if the number of monochromatic copies of $H$ in a 2-edge-colouring of the complete graph $K_n$ is asymptotically minimised by the random colouring. We prove that, given $k,r>0$, there exists a $k$-connected common graph with chromatic number at least $r$. The result is built upon the recent breakthrough of Kr\'a\v{l}, Volec, and Wei who obtained common graphs with arbitrarily large chromatic number and answers a question of theirs.Comment: 6 page

Smart teachers as updatable software:A genealogical examination of teacher subjectivity in the era of technology

Teachers nowadays are expected to be fluent in using technology that would ‘work like magic’ in their classrooms. It would be very unwise for teachers to publicly criticise the value of digital technologies where the governments around the world put enormous efforts to innovate their education by implementing education technology reforms. In this context, this research elucidates the formation of a specific teacher subjectivity at this specific historical juncture to rethink what we are seeing as the smart teacher. As a research method, this study employs a ‘genealogy’ which enables to examine rules, norms, and knowledge of contemporary discourses about ‘SMART education’, an education technology initiative in South Korea. To identify what the target discourses produce, this paper uses ‘four-part Foucauldian framework’ to demonstrate the constructed teacher subject: 1) What aspects of teachers needed to change (substance), 2) For what reason should this change happen (mode), 3) What are teachers supposed to do to change themselves (the regimen), 4) What a model or perfect version of teacher might look like (telos). In order to appreciate each axis, I analyse public documents (e.g. national policies, research reports, news articles), and interview transcripts with the detailed analytical tools provided by Fairclough (2003). I argue that the ‘smart teacher’ is positioned as ‘updatable software’ which is to be thoroughly, constantly, ubiquitously and autonomously updatable. I discuss SMART education discourses is the complex of seemingly organised but coarse articulation of disparate discourses. Further, I contend that the identified teacher subjectivity might not be smart in so far as teachers are supposed to be ‘receptive’ in relation to external changes rather than teachers being proactive or critical. Ultimately, I recommend that we open up our discussions regarding different possibilities by re-imagining future versions of education and teachers

FDCNet: Feature Drift Compensation Network for Class-Incremental Weakly Supervised Object Localization

This work addresses the task of class-incremental weakly supervised object localization (CI-WSOL). The goal is to incrementally learn object localization for novel classes using only image-level annotations while retaining the ability to localize previously learned classes. This task is important because annotating bounding boxes for every new incoming data is expensive, although object localization is crucial in various applications. To the best of our knowledge, we are the first to address this task. Thus, we first present a strong baseline method for CI-WSOL by adapting the strategies of class-incremental classifiers to mitigate catastrophic forgetting. These strategies include applying knowledge distillation, maintaining a small data set from previous tasks, and using cosine normalization. We then propose the feature drift compensation network to compensate for the effects of feature drifts on class scores and localization maps. Since updating network parameters to learn new tasks causes feature drifts, compensating for the final outputs is necessary. Finally, we evaluate our proposed method by conducting experiments on two publicly available datasets (ImageNet-100 and CUB-200). The experimental results demonstrate that the proposed method outperforms other baseline methods.Comment: ACM Multimedia 202

Reconceptualising a good teacher in SMART education:A Foucauldian Critical Discourse Analysis

While using technology in the classroom has been taken for granted as ‘good thing’ or ‘smart thing’, improving students learning, many teacher educators have argued teachers need to develop technology-related professionality. Teachers have been trained to teach with technology for many years, but many teachers still seem to find the effective integration of technology in their teaching challenging and it is yet rare to see smart enough classroom practices. This research aims to understand, based on Foucault’s theoretical notions of ‘discourse’ and ‘power’, the formation of such a gap between the technology-focused educational claims and the actual reality of teachers’ educational practices. The study is situated in a specific educational context of promoting an idea of “SMART education” in South Korea. It will closely investigate a set of claims about technology, teaching, and teachers in the SMART education discourse and their construction, circulation, and influences on teachers’ practices by collecting and analysing language use in various texts. An ultimate purpose of the study is to deconstruct the taken-for-granted assumptions related to the SMART education, which seem to impose certain pedagogical ideas upon teachers, which may not support teachers’ classroom practices in reality

Digital Pharmacists with the Panacea in the New Paradigm:Discursive Formation of a Good Teacher in Digital Era

Teachers today face ever-increasing demands in teaching to ensure that their students are to be well equipped to be competent in the 21st century. Among many demands, teachers are expected to be fluent, versatile, and professional in using technology based on the taken-for-granted beliefs that technology has a good and innovative influence on education. However, while it is hard to hear that innovation has completed, it is easy to see teachers still find the effective integration of technology in their practices complicated. The purpose of the study is to investigate the formation of the gap between what has been commonly claimed regarding technology use and what has been seen by educators in the classrooms. By drawing Foucault’s theory of discourse and power, this research will examine a set of claims produced in the process of promoting an educational policy “SMART education” in South Korea. The study ultimately aims to demystify taken-for-granted assumptions related to SMART education which invisibly urge teachers to accept and conform regardless of what teachers find in their classrooms

Virtualizing Graphics Architecture of Android Mobile Platforms in KVM/ARM Environment

With the availability of virtualization extension in mobile processors, e.g. ARM Cortex A-15, multiple virtual execution domains are efficiently supported in a mobile platform. Each execution domain requires high-performance graphics services for full-featured user interfaces such as smooth scrolling, background image blurring, and 3D images. However, graphics service is hard to be virtualized because multiple service components (e.g. ION and Fence) are involved. Moreover, the complexity of Graphical Processing Unit (GPU) device driver also makes harder virtualizing graphics service. In this paper, we propose a technique to virtualize the graphics architecture of Android mobile platform in KVM/ARM environment. The Android graphics architecture relies on underlying Linux kernel services such as the frame buffer memory allocator ION, the buffer synchronization service Fence, GPU device driver, and the display synchronization service VSync. These kernel services are provided as device files in Linux kernel. Our approach is to para-virtualize these device files based on a split device driver model. A major challenge is to translate guest-view of information into host-view of information, e.g. memory address translation, file descriptor management, and GPU Memory Management Unit (MMU) manipulation. The experimental results show that the proposed graphics virtualization technique achieved almost 84%-100% performance of native applications.11Ysciescopu

A characterization of graphs of radius-rr flip-width at most 22

The $r$-flip-width of a graph, for $r\in \mathbb{N}\cup \{\infty\}$, is a graph parameter defined in terms of a variant of the cops and robber game, called a flipper game, and it was introduced by Toru\'{n}czyk [Flip-width: Cops and robber on dense graphs, arXiv:2302.00352]. We prove that for every $r\in (\mathbb{N}\setminus \{1\})\cup \{\infty\}$, the class of graphs of $r$-flip-width at most $2$ is exactly the class of ($C_5$, bull, gem, co-gem)-free graphs, which are known as totally decomposable graphs with respect to bi-joins.Comment: 14 pages, 1 figur

The impact of weight misperception on health-related quality of life in Korean adults (KNHANES 2007–2014): a community-based cross-sectional study

Weight perception, especially misperception, might affect health-related quality of life (HRQoL); however, related research is scarce and results remain equivocal. We examined the association between HRQoL and weight misperception by comparing obesity level as measured by body mass index (BMI) and weight perception in Korean adults
