TL;DR: The results showed that the experimental group made significantly more annotations across almost all types of reading annotations and response annotations and had a significantly higher degree of immersive experience and social interaction than the control group, however, the difference in reading comprehension performance between the two groups has not been found.
Abstract: This study presents a web-based collaborative reading annotation system (WCRAS) with gamification mechanisms to motivate students' annotations behaviors and promote students' reading comprehension performance. The research participants were 55 fifth grade students from two classes of an elementary school in northeastern Taiwan. A quasi-experimental design was adopted to evaluate the effects of the experimental and control groups respectively using WCRAS with and without gamification mechanisms to support digital reading on students' annotation behaviors, collaborative interaction relationship, reading comprehension performance, and immersion experience. The results showed that the experimental group made significantly more annotations across almost all types of reading annotations and response annotations and had a significantly higher degree of immersive experience and social interaction than the control group. However, the difference in reading comprehension performance between the two groups has not been found. In addition, although the experimental group provided more amounts of high-quality annotations, the group did not generate more quantity of annotations related to reading comprehension aspects assessed by PIRLS. These research findings indicate that a gap between the promotion of the quantity and quality of participation and learning outcomes exists. This study is significant to address the need that designs the gamification mechanisms to encourage high-quality annotations that can effectively enhance students’ reading comprehension. To better associate game features and learning performance in the WCRAS with gamification mechanisms, future studies are suggested to promote both annotation quality and connection between reading achievement and gamification mechanisms.

TL;DR: The authors showed that investors systematically exaggerate corporate ESG information, leading to ESG momentum effects in financial markets, which can lead to substantial profits in the short run and reversals in the long run.
Abstract: As environmental, social, and governance (ESG) factors become increasingly important in the business sector, investors pay more attention to corporate ESG information. Integrating ESG factors into the investment process has transformed from a niche to mainstream activity. This study demonstrates that investors systematically exaggerate corporate ESG information, leading to ESG momentum effects in financial markets. Specifically, investors exhibit optimistic responses to good news about companies with higher ESG scores but pessimistic responses to bad news about companies with lower ESG scores. Consistent with the overreaction hypothesis, the empirical results show that an ESG momentum strategy can lead to substantial profits in the short run and reversals in the long run. Moreover, this study reveals that investors overreact to the environmental factor more than social or governance factors.

TL;DR: The results show that investors' breadth of investment experience influences firms' ability to innovate by affecting firms' abilities to innovate, once the authors factor in the types of investors and their capabilities.
Abstract: Research Summary We add to the literature examining the ownership‐innovation relationship by examining two major investor types: corporate investors and family investors. We use organizational environmental scanning as a new perspective to understand how these investors' capabilities influence firms' external cooperation and innovation performance. We found that corporate investors with broad investment experience strengthen a firm's environmental scanning, enhancing innovation performance by increasing the number of external cooperation activities the firm engages in. Conversely, family investors' broad investment experience tend to be negatively associated with the number of external cooperation and with firm innovation. Our results show that investors influence firm innovation not simply through a monitoring role but also by affecting firms' abilities to innovate, once we factor in the types of investors and their capabilities. Managerial Summary We investigate how two different types of investors, corporate and family, influence the innovation performance of publicly‐traded high‐tech firms in Taiwan. We found that the presence of major corporate investors with broad investment experience enhances firms' innovation performance by increasing external cooperation activities firms engage in. Corporate investors appear to enhance organizations' environmental scanning abilities and, in turn, their innovation performance. Conversely, family investors' broad investment experience is negatively associated with firm innovation because such firms engage in fewer external cooperation activities. A focus on control and social cohesion in family firms appears to decrease the emphasis on external knowledge acquisition when family investors have broad investment experience. In summary, our results show that investors' breadth of investment experience influences firms' ability to innovate.

TL;DR: Study findings suggest that young adults’ mental health, at least under certain contexts, is more closely linked with the nature and pattern of ACE co-occurrence, rather than the number of ACEs.
Abstract: Adverse childhood experiences (ACEs) constitute a significant global mental health burden. Prior studies typically investigated the impact of ACEs on mental health using a cumulative risk approach; most ACEs studies were also conducted in Western settings. This study aimed to examine ACEs using a pattern-based approach and assess their associations with mental health outcomes by early adulthood in East Asia. The present study included measures of exposure to 13 categories of ACEs, depression, anxiety, maladjustment, and posttraumatic stress in a sample of 1346 university students from Hong Kong, China, Taiwan, and Japan. Latent class analysis indicated three distinct patterns of ACE exposure: Class 1: Low ACEs (76.0%); Class 2: Household Violence (20.6%); and Class 3: Household Dysfunction (3.4%). Those representing Class 3 had significantly more ACEs compared with those in Classes 1 or 2. Controlling for age and sex, those in Class 2 reported significantly higher depression and maladjustment symptoms compared with those in Class 1; both Classes 2 and 3 had significantly higher anxiety symptoms and odds for meeting diagnostic criteria for posttraumatic stress disorders compared with those in Class 1. Study findings suggest that young adults’ mental health, at least under certain contexts, is more closely linked with the nature and pattern of ACE co-occurrence, rather than the number of ACEs.

TL;DR: A novel approach to prepare a synaptic transistor by doping conjugated polymers, which can promote the future development of artificial neuromorphic systems, is described.
Abstract: Brain-inspired synaptic transistors have been considered as a promising device for next-generation electronics. To mimic the behavior of a biological synapse, both data processing and nonvolatile memory capability are simultaneously required for a single electronic device. In this work, a simple approach to realize a synaptic transistor with improved memory characteristics is demonstrated by doping an ionic additive, tetrabutylammonium perchlorate (TBAP), into an active polymer semiconductor without using any extra charge storage layer. TBAP doping is first revealed to improve the memory window of a derived transistor memory device from 19 to 32 V (∼68% enhancement) with an on/off current ratio over 103 at VG = -10 V. Through morphological analysis and theoretical calculations, it is revealed that the association of anion with polymers enhances the charge retention capability of the polymer and facilitates the interchain interactions to result in improved memory characteristics. More critically, the doped device is shown to successfully mimic the synaptic behaviors, such as paired-pulse facilitation (PPF), excitatory and inhibitory postsynaptic currents, and spike-rate dependent plasticity. Notably, the TBAP-doped device is shown to deliver a PPF index of up to 204% in contrast to the negligible value of an undoped device. This study describes a novel approach to prepare a synaptic transistor by doping conjugated polymers, which can promote the future development of artificial neuromorphic systems.

TL;DR: AI has the potential to assist radiologists or serve as a reasonable alternative for pre-operative evaluation of the myometrial invasion depth of stage I endometrial cancers and was more likely to provide incorrect interpretations in patients with coexisting benign leiomyomas or polypoid tumors.
Abstract: Myometrial invasion affects the prognosis of endometrial cancer. However, discrepancies exist between pre-operative magnetic resonance imaging staging and post-operative pathological staging. This study aims to validate the accuracy of artificial intelligence (AI) for detecting the depth of myometrial invasion using a deep learning technique on magnetic resonance images. We obtained 4896 contrast-enhanced T1-weighted images (T1w) and T2-weighted images (T2w) from 72 patients who were diagnosed with surgico-pathological stage I endometrial carcinoma. We used the images from 24 patients (33.3%) to train the AI. The images from the remaining 48 patients (66.7%) were used to evaluate the accuracy of the model. The AI then interpreted each of the cases and sorted them into stage IA or IB. Compared with the accuracy rate of radiologists’ diagnoses (77.8%), the accuracy rate of AI interpretation in contrast-enhanced T1w was higher (79.2%), whereas that in T2w was lower (70.8%). The diagnostic accuracy was not significantly different between radiologists and AI for both T1w and T2w. However, AI was more likely to provide incorrect interpretations in patients with coexisting benign leiomyomas or polypoid tumors. Currently, the ability of this AI technology to make an accurate diagnosis has limitations. However, in hospitals with limited resources, AI may be able to assist in reading magnetic resonance images. We believe that AI has the potential to assist radiologists or serve as a reasonable alternative for pre-operative evaluation of the myometrial invasion depth of stage I endometrial cancers.

TL;DR: WalkingVibe, which applies unobtrusive vibrotactile feedback for VR walking experiences, and also reduces VR sickness and discomfort while improving realism, is proposed, which is a practical approach for improving VR experiences with new and existing VR headsets.
Abstract: Virtual Reality (VR) sickness is common with symptoms such as headaches, nausea, and disorientation, and is a major barrier to using VR. We propose WalkingVibe, which applies unobtrusive vibrotactile feedback for VR walking experiences, and also reduces VR sickness and discomfort while improving realism. Feedback is delivered through two small vibration motors behind the ears at a frequency that strikes a balance in inducing vestibular response while minimizing annoyance. We conducted a 240-person study to explore how visual, audio, and various tactile feedback designs affect the locomotion experience of users walking passively in VR while seated statically in reality. Results showed timing and location for tactile feedback have significant effects on VR sickness and realism. With WalkingVibe, 2-sided step-synchronized design significantly reduces VR sickness and discomfort while significantly improving realism. Furthermore, its unobtrusiveness and ease of integration make WalkingVibe a practical approach for improving VR experiences with new and existing VR headsets.
TL;DR: This article provided a comprehensive review of the growth of multinational enterprises (MNEs) based on a quarter-century (25 years) of scholarly international business publications and synthesized research insights on the determinants of MNEs through the lens of Penrose's theory of firm growth.
Abstract: We provide a comprehensive review of the growth of multinational enterprises (MNEs) based on a quarter-century (25 years) of scholarly international business publications. We synthesize research insights on the determinants of the growth of MNEs through the lens of Penrose’s theory of firm growth, which is the most influential theoretical perspective on firm growth. The review takes stock of the research findings on the facilitators, constraints, and the trajectory of growth of MNEs, and elaborates on the commonalities and differences between research on the growth of MNEs that draws on Penrose’s theory and research that does not. This comparison highlights the opportunity to build an internally coherent theory of the growth of MNEs, that is, a theory that connects ‘what an MNE is’ to ‘what determines an MNE’s growth.’ It also indicates that past research placed a strong emphasis on exogenous factors (e.g., cross-country distances) as key constraints on growth even though the Penrosean lens suggests a close consideration of endogenous factors that drive international growth, as well as endogenizing the ostensibly exogenous growth determinants. The review highlights the importance of firm-specific managerial knowledge and learning, which shapes the direction of the growth of MNEs and ensures its administrative coherence.
TL;DR: In this article, the authors examine whether and how private firms differ from public firms in determining corporate social responsibility (CSR) disclosure policies and find that private firms are less likely to issue CSR reports compared with their public peers.
Abstract: We examine whether and how private firms differ from public firms in determining corporate social responsibility (CSR) disclosure policies. We document that private firms are less likely to issue CSR reports compared with their public peers. Adopting a bivariate probit model that accommodates partial observability, we find that the effect is mainly driven by a supply-side force rather than a demand-side force. From a debtholder-oriented perspective, while public firms enjoy more favorable credit ratings and a lower cost of debt due to CSR disclosure, private firms do not reap similar benefits from CSR disclosure. Corporate governance and CSR assurance alleviate debtholders' concern on private firms’ engagements in CSR.

TL;DR: A novel framework relating transparency, stages of automation, and trust in automation is proposed in which transparency plays a primary role in decisions to use automation but is supplemented by trust where there is insufficient information otherwise.
Abstract: The reported study compares groups of 120 participants each, from the United States (U.S.), Taiwan (TW), and Turkey (TK), interacting with versions of an automated path planner that vary in transparency and degree of automation. The nationalities were selected in accordance with the theory of cultural syndromes as representatives of Dignity (U.S.), Face (TW), and Honor (TK) cultures, and were predicted to differ in readiness to trust automation, degree of transparency required to use automation, and willingness to use systems with high degrees of automation. Three experimental conditions were tested. In the first, highlight , path conflicts were highlighted leaving rerouting to the participant. In the second, replanner made requests for permission to reroute when a path conflict was detected. The third combined condition increased transparency of the replanner by combining highlighting with rerouting to make the conflict on which decision was based visible to the user. A novel framework relating transparency, stages of automation, and trust in automation is proposed in which transparency plays a primary role in decisions to use automation but is supplemented by trust where there is insufficient information otherwise. Hypothesized cultural effects and framework predictions were confirmed.
TL;DR: In the time of COVID-19 covered by this study, about three-fifths of the hospitals in Taiwan had posted their visiting policies for ordinary wards on their websites, and the thoroughness with which such visiting policies have been enforced also requires investigation.
Abstract: BACKGROUND: Coronavirus disease 2019 (COVID-19), a novel infectious coronavirus disease, has become a worldwide pandemic. Infection control precautions for hospital visitors are needed to avoid cluster outbreaks, so this study investigated the visiting policies of all the hospitals in Taiwan in the time of COVID-19. METHODS: From March 15, 2020, to March 18, 2020, we searched the official websites of all 472 National Health Insurance-contracted hospitals to determine their visiting policies. For those hospitals that had posted new visiting policies and still allowed visits to ordinary wards, we recorded the relevant details shown on their websites, including the number of visitors allowed at one time, the number of visiting slots per day, the total visiting hours per day, and the rules provided to visitors before visiting. RESULTS: During the study period, 276 (58.5%) hospitals had posted new visiting policies on their websites, with higher proportions of academic medical centers (92.0%, 23/25) and metropolitan hospitals (91.5%, 75/82) than local community hospitals (48.8%, 178/365) doing so. Visits to ordinary wards were forbidden in 83 hospitals among those. Among the 193 hospitals that had new visiting policies and still allowed visits to ordinary wards, 73.1% (n = 141) restricted visitors to two at a time and 54.9% (n = 106) restricted visits to two visiting slots per day. Furthermore, history taking regarding travel, occupation, contacts, and cluster information was mentioned by 82.4% (n = 159) of these 193 hospitals, body temperature monitoring by 78.2% (n = 151), hand hygiene by 63.2% (n = 122), and identity checks by 51.8% (n = 100). CONCLUSION: In the time of COVID-19 covered by this study, about three-fifths of the hospitals in Taiwan had posted their visiting policies for ordinary wards on their websites. Furthermore, the thoroughness with which such visiting policies have been enforced also requires investigation.

TL;DR: An overview of RFID-based relay attacks is provided and distance-bounding techniques and the use of artificial or natural ambient conditions are considered, with specific emphasis on the latter.
Abstract: Relay attacks generally occur between two entities that communicate with each other through wireless means. When a relay attack between a honest prover and a honest verifier occurs, an adversary tricks the prover and verifier into believing that they are indeed communicating with each other. Such attacks are rather difficult to identify and prevent since a passive adversary does not modify any of the communicated messages between prover and verifier. RFID/NFC-based applications are particularly vulnerable to such attacks. We provide an overview of RFID-based relay attacks and evaluate various streams of research that have attempted to address these attacks. Specifically, we consider distance-bounding techniques and the use of artificial or natural ambient conditions, with specific emphasis on the latter.
TL;DR: In this paper, the authors examine whether information technology (IT) helps firms to overcome the liabilities of global operations particularly when it comes to creation of exploratory innovations, and they draw on the knowledge-based view of the firm and hypothesize that IT-enabled social integration capacity influences exploratory innovation by enabling firms to leverage global cultural diversity and global geographical dispersion.
Abstract: Although the ability to produce exploratory innovations is important for firm performance, firms face difficulties in producing exploratory innovations because knowledge is often distributed across cultures and geographies. In this study, we examine whether information technology (IT) helps firms to overcome the liabilities of global operations particularly when it comes to creation of exploratory innovations. We argue that information technologies that promote social integration facilitate more novel knowledge recombinations that help to overcome the difficulties arising from global operations. We draw on the knowledge-based view of the firm and hypothesize that IT-enabled social integration capacity influences exploratory innovation by enabling firms to leverage global cultural diversity and global geographical dispersion. Our empirical analyses using archival panel data from 120 public U.S. manufacturing firms from 2003 to 2014 support these hypotheses. A key implication of our results is that IT helps firms to achieve greater exploratory innovation by turning the potential liabilities of cultural diversity and geographical dispersion associated with global operations into assets.
