Recently, decoupling between the US and China has emerged as an important issue in global economics. We propose an analytical framework for trade decoupling analysis, borrowing the idea from the production function in non-competitive input-output tables. Using that methodology, we analyze the mobile phone trade network subject to various measures imposed by the US. A scenario analysis is performed to compare the extent of decoupling after a trade war with worst-cases. In bilateral trade, China’s share of total US imports fell significantly in 2019 compared to 2017. However, China’s indirect exports to the US increased during the same period. A similar pattern is observed in the global trade network visualized via multidimensional scaling (MDS). China’s out-degree centrality decreased slightly, while Vietnam’s role expanded. Actual figures for 2019 show a decreased out-degree centrality for Chinese final good exports, but a much higher one in the scenarios. Also, China’s indirect exports to the US have increased. But China does not appear to play a key role in the network as assumed in the scenario. Throughout the study, intermediate goods were treated homogeneously, and further studies considering the heterogeneity of input-output linkages are needed.

Data literacy empowers college students, equipping them with essential skills necessary for their personal lives and careers in today’s data-driven world. This study aims to explore how community college students evaluate their data literacy and further examine demographic and educational/career advancement disparities in their self-assessed data literacy levels.

An online survey presenting a data literacy self-assessment scale was distributed and completed by 570 students at four community colleges. Statistical tests were performed between the data literacy factor scores and students’ demographic and educational/career advancement variables.

Male students rated their data literacy skills higher than females. The 18–19 age group has relatively lower confidence in their data literacy scores than other age groups. High school graduates do not feel proficient in data literacy to the level required for college and the workplace. Full-time employed students demonstrate more confidence in their data literacy than part-time and nonemployed students.

Given the lack of research on community college students’ data literacy, the findings of this study can be valuable in designing and implementing data literacy training programs for different groups of community college students.

This study aims to understand the technical and operational challenges encountered by multilingual digital libraries and their strategies to solve problems in sustaining multilinguality services for digital libraries.

Using the multiple-case method, this study investigated two digital libraries that have sustained multilinguality for over a decade: the World Digital Library and the Digital Library of the Caribbean.

This study identified eight factors that contributed to the success of the two multilingual digital libraries and eight technical and operational challenges they have faced. A framework for digital libraries to sustain multilinguality is proposed. This framework illustrates the challenges and strategies to address the challenges in 11 aspects: creation, leadership, collaboration, content, metadata, translation, funding, technology, preservation, staffing and copyright.

This study focused on two multilingual digital libraries administered in the USA, though they do not fully represent multilingual digital libraries in the USA. Therefore, the findings from the study may not apply to multilingual digital libraries the USA or other countries. As on-site interviews of both digital libraries were conducted at the beginning of 2019, the timeframe of this study is up to that date.

With more users worldwide seeking information online, more digital libraries will be providing multilingual services. This study provides guidelines to digital library developers and archivists for building and sustaining their digital libraries or archives. The experience and lessons learned from these two digital libraries may also help to better understand challenges and use effective strategies in building and sustaining multilinguality.

The users and communities of digital libraries will be able to learn the benefits and challenges as related to building and sustaining digital library services. These services always need support to better serve their users and communities.

As the first multiple-case research that investigates in-depth challenges and approaches of digital libraries in sustaining multilinguality, this study presents a general picture of how the two digital libraries have succeeded in sustaining multilinguality. Theoretically, the study enriches the literature by providing a more comprehensive sustainability framework for multilinguality. This framework specifies possible aspects to consider for gaining sustainability of multilingual digital libraries and offers useful guidelines and insights for the digital library community to build multilingual services.

The purpose of this paper is to present a review on the use of the recall metric for evaluating information retrieval systems, especially search engines.

This paper investigates different researchers’ views about recall metrics.

Five different definitions for recall were identified. For the first group, recall refers to completeness, but it does not specify where all the relevant documents are located. For the second group, recall refers to retrieving all the relevant documents from the collection. However, it seems that the term “collection” is ambiguous. For the third group (first approach), collection means the index of search engines and, for the fourth group (second approach), collection refers to the Web. For the fifth group (third approach), ranking of the retrieved documents should also be accounted for in calculating recall.

It can be said that in the first, second and third approaches, the components of the retrieval algorithm, the retrieval algorithm and crawler, and the retrieval algorithm and crawler and ranker, respectively, are evaluated. To determine the effectiveness of search engines for the use of users, it is better to use the third approach in recall measurement.

The value of this paper is to collect, identify and analyse literature that is used in recall. In addition, different views of researchers about recall are identified.

This research is motivated to explore communication professionals' understanding of the digital changes brought by the Industry 4.0 revolution and how such changes may affect the strategies and skills expected in effective communication management. A specific focus of the research is to define the concept of Readiness for Industry 4.0 in communication and propose a theoretical framework to address the key dimensions of Readiness for Industry 4.0 as related to communication management.

A mixed research design was employed to fulfill the goal of this research. First, the authors took a grounded theory approach in proposing, conceptualizing and constructing the concept of Readiness for Industry 4.0 by reviewing a wider literature on technology and communication. As part of the conceptualization process, the authors proposed five dimensions which encompass the complexity of building capacity in communication practice to effectively manage changes associated with Industry 4.0. Second, the authors used a qualitative research method, in-depth interviews, to gain insights from 16 senior communication professionals working in South Korea.

The study’s interview results confirmed the challenge in finding a universal definition of Readiness for Industry 4.0, even though the interviewed senior communication professionals have widely recognized the changes in the workplace brought by the Industry 4.0. Our interviewees agreed that their mindset is ready for the changes. However, they addressed the need for communication professionals to continue to learn and build their knowledge and skills from multiple perspectives. More specifically, skill sets and knowledge in cognitive analytics, data management, technology literacy, sense making skills for digital transformation and digital competencies in crisis management are desired and necessary.

This research advances theory building in communication management by addressing the importance of digital competencies in the workplace. By proposing a theoretical framework to explain the Readiness for Industry 4.0, this article contributes to our knowledge of digital transformation and its impact on effective communication. Moreover, by having deep conversations with industry leaders who are in the forefront of managing the challenges associated with technology advancement, this article enriches its practical implications by linking the discussion to the proposed theoretical framework.
