ISTopic: Understanding Information Systems Research through Topic Models
What are the fundamental research questions in Information Systems? How do various research topics relate with one another to form the IS research landscape and how do they evolve over time? This study is an initial attempt to answer these questions using topic models to investigate the topics examined by the premier IS journals in 1977-2014. We present an IS Topic Graph that contains 33 research areas, 31 of which are closely connected with one another. Further analyses of this graph reveal how different IS research areas are intertwined to the extent that they are almost inseparable. Looking into IS research at a finer level, we identify 300 research topics, and a chronological analysis reveals a trend of topic diversification and externalization. To guide future research, an intelligent literature search tool called ISTopic is built and is available at http://www.istopic.org for public access
Internationalization of Regional Higher Education in China: A Critical Policy Case Study of A Transnational Double-Degree Program
Abstract
While internationalization is omnipresent in the Chinese universities’ policy rhetoric and internationalization initiatives have been widely carried out, current research of China’s higher education internationalization mainly concentrates on the top research universities. This dissertation shifts the focus to study the internationalization of higher education in regional universities in China. Situated in the critical policy analytical framework, this study used qualitative case study approach to investigate national and institutional level perceptions of higher education internationalization in the Chinese context with a focus on a specific internationalization initiative, a double-degree program (SNZDD), in one regional public university (RU). Bourdieu’s concepts of field and capital were also used. The dissertation examines the following questions: 1. How is the internationalization of higher education conceptualized in the policies at national and institutional levels? 2. What has driven RU to engage in the process of the internationalization of higher education? 3. How has the SNZDD program benefited RU and the students associated with the SNZDD program? And 4. What are the challenges associated with the SNZDD program at RU?
This study found that the internationalization of the Chinese regional university has been mostly driven by an instrumentalist ideology (political and economic purposes) and partially driven by an educationalist ideology (academic purpose). The institutional internationalization ideology is consistent with the national internationalization ideology. A gap in understanding about internationalization between the higher university leaders/administrators and instructors has led to an imbalance in policy making involvement between these two groups. This study also found that market-based higher education internationalization may generate inequality in the long run.
This study recommends including university administrators, instructors and students in internationalization policy making and implementation
An investigation of the perceptions of foreign ESL teachers in China towards teacher accountability: a comparison between Chinese ESL teachers and foreign ESL teachers in China
This study investigated external and internal accountability of foreign ESL teachers in China through a comparison with Chinese local ESL teachers. A cross-sectional survey design was used. Two research questions were developed from a literature review to examine foreign ESL teachers' perceptions toward external accountability and internal accountability.
Questionnaires from forty-five ESL teachers and eighty-one Chinese local ESL teachers were collected through an on-line survey. Data of teachers' perceptions towards four constructs: external accountability (outside expectations), external accountability (school management), internal accountability (professional duty), and internal accountability (feelings about work), were analyzed. The findings showed that foreign teachers perceived that they were held externally accountable with regard to outside expectations, and they were not held externally accountable for school management. In terms of internal accountability, foreign teachers perceived that they held themselves highly accountable in both the construct of professional duty and the construct of feelings about work
ADBench: Anomaly Detection Benchmark
Given a long list of anomaly detection algorithms developed in the last few
decades, how do they perform with regard to (i) varying levels of supervision,
(ii) different types of anomalies, and (iii) noisy and corrupted data? In this
work, we answer these key questions by conducting (to our best knowledge) the
most comprehensive anomaly detection benchmark with 30 algorithms on 57
benchmark datasets, named ADBench. Our extensive experiments (98,436 in total)
identify meaningful insights into the role of supervision and anomaly types,
and unlock future directions for researchers in algorithm selection and design.
With ADBench, researchers can easily conduct comprehensive and fair evaluations
for newly proposed methods on the datasets (including our contributed ones from
natural language and computer vision domains) against the existing baselines.
To foster accessibility and reproducibility, we fully open-source ADBench and
the corresponding results.Comment: NeurIPS 2022. All authors contribute equally and are listed
