Managing knowledge networks
\"The information context of the modern organization is rapidly evolving in the face of intense global competition. Information technologies, including databases, new telecommunications systems, and software for synthesizing information, make a vast array of information available to an ever expanding number of organizational members. Management's exclusive control over knowledge is steadily declining, in part because of the downsizing of organizations and the decline of the number of layers in an organizational hierarchy. These trends, as well as issues surrounding the Web 2.0 and social networking, mean that it is increasingly important that we understand how informal knowledge networks impact the generation, capturing, storing, dissemination, and application of knowledge. This innovative book provides a thorough analysis of knowledge networks, focusing on how relationships contribute to the creation of knowledge, its distribution within organizations, how it is diffused and transferred, and how people find it and share it collaboratively\"--Provided by publisher.

Providing a Web-based Online Medical Record with Electronic Communication Capabilities to Patients With Congestive Heart Failure: Randomized Trial
It is possible to provide patients with secure access to their medical records using the Internet. Such access may assist patients in the self-management of chronic diseases such as heart failure.
To assess how a patient-accessible online medical record affects patient care and clinic operations. The SPPARO (System Providing Access to Records Online) software consisted of a web-based electronic medical record, an educational guide, and a messaging system enabling electronic communication between the patient and staff.
A randomized controlled trial was conducted in a specialty practice for patients with heart failure. Surveys assessing doctor-patient communication, adherence, and health status were conducted at baseline, 6 months, and 1 year. Use of the system, message volume, utilization of clinical services, and mortality were monitored.
One hundred and seven patients were enrolled (54 intervention and 53 controls). At 12 months, the intervention group was not found to be superior in self-efficacy (KCCQ self-efficacy score 91 vs. 85, p=0.08), but was superior in general adherence (MOS compliance score 85 vs. 78, p=0.01). A trend was observed for better satisfaction with doctor-patient communication. The intervention group had more emergency department visits (20 vs. 8, p=0.03), but these visits were not temporally related to use of the online medical record. There were no adverse effects from use of the system.
Providing patients with congestive heart failure access to an online medical record was feasible and improved adherence. An effect on health status could not be demonstrated in this pilot study.

Emerging trends of online assessment systems in the emergency remote teaching period
The COVID-19 pandemic caused many educational institutions in the world to switch to the distance education process, and this process was called \"Emergency Remote Teaching\". This urgent transition process has caused many problems in educational environments. One of the problems is the subject of measurement and evaluation. Along with the pandemic, many institutions have used various online assessment systems to make measurements and evaluations online, and researchers have conducted research on these online assessment systems. This research focus on the features of the online assessment systems and aims to examine the trends towards the prominent features of the online assessment systems in the Emergency Remote Teaching period. For this purpose, the prominent online assessment systems have been determined by systematically analyzing academic studies published in 2020, and answers have been sought to the following research questions: (1) which platforms they support, (2) which security features they have, and (3) what common features they have. Identifying trends in the characteristics of online assessment systems is expected to guide practitioners, decision-makers, researchers, and system developers in the process of selecting and/or developing an online assessment system for use in online measurement and evaluation.

Proof of stake : the making of Ethereum and the philosophy of blockchains
\"After Ethereum creator Vitalik Buterin dropped out of college and launched Bitcoin Magazine, he wrote the Ethereum white paper, which proposed an open source system that would take what Bitcoin did for money and do it for everything else: contracts, social networks, and sharing economies. Now, less than a decade later, his idea is valued at about half a trillion dollars, and it is the foundation for the weird new world of NFT artworks, virtual real estate, and decentralized autonomous organizations. Understanding and engaging with Buterin's ideas will be of growing importance as the consequences of his invention continue to unfold and inspire debate worldwide. These writings, collected from his essays before and during the rise of Ethereum, reveal Buterin to be a vivid and imaginative writer, and this edition includes context from media studies scholar Nathan Schneider. While many around him were focused on seeing the value of their tokens rise, Buterin was working through the problems and possibilities of crafting an Internet-native world\"-- Provided by publisher.

Patient-reported adverse effects of high-dose intravenous methylprednisolone treatment: a prospective web-based multi-center study in multiple sclerosis patients with a relapse
In a prospective multi-center observational study, we evaluated the frequency, severity, and impact on activities of daily living (ADL) of adverse effects (AEs) of high-dose intravenous methylprednisolone (IVMP) in relapsing remitting multiple sclerosis (MS) patients with a relapse. Online self-report questionnaires stating IVMP’s most common AEs were completed at baseline, the 2nd day of treatment, and 1 day and 1 week after treatment. Eighty-five patients were included, 66 completed the baseline questionnaire, and 59 completed at least one post-baseline questionnaire. Patients reported on average 4 (median) AEs; two (3.4 %) reported no AE. Most frequent was change in taste (61 %), facial flushing (61 %), sick/stomach pain (53 %), sleep disturbance (44 %), appetite change (37 %), agitation (36 %), and behavioral changes (36 %). Of all AEs, 34.3 % were severe and 37.9 % impacted on ADL. A 3-day course resulted in 4 (median) AEs and a 5-day course in 7. All patients with high disease impact had two or more AEs, compared with 79 % of those with low impact (
p
< 0.01). Of patients with high disability, 45 % had severe AEs, compared with 16 % of those with low disability. Severe central nervous system (CNS)-related AEs occurred two times more frequently in patients with high disease impact, and two-and-a-half times more frequently in patients with high disability. Therefore, in virtually all patients, high-dose IVMP leads to AEs, with about one of three AEs being severe with impact on ADL. Patients with high disease impact or high disability may experience more (severe) AEs, due to a higher occurrence of severe CNS-related AEs.

A randomized trial found online questionnaires supplemented by postal reminders generated a cost-effective and generalizable sample but don’t forget the reminders
The objective of this study was to compare the response rates, data completeness, and representativeness of survey data produced by online and postal surveys.
A randomized trial nested within a cohort study in Yorkshire, United Kingdom. Participants were randomized to receive either an electronic (online) survey questionnaire with paper reminder (N = 2,982) or paper questionnaire with electronic reminder (N = 2,855).
Response rates were similar for electronic contact and postal contacts (50.9% vs. 49.7%, difference = 1.2%, 95% confidence interval: −1.3% to 3.8%). The characteristics of those responding to the two groups were similar. Participants nevertheless demonstrated an overwhelming preference for postal questionnaires, with the majority responding by post in both groups.
Online survey questionnaire systems need to be supplemented with a postal reminder to achieve acceptable uptake, but doing so provides a similar response rate and case mix when compared to postal questionnaires alone. For large surveys, online survey systems may be cost saving.

Flipped classroom frameworks improve efficacy in undergraduate practical courses – a quasi-randomized pilot study in otorhinolaryngology
Background
Curriculum design and specific topic selection for on-site practical courses in clinical disciplines with limited teaching time is challenging. An electronic learning supported curriculum based on the flipped classroom principle has a high potential to effectively gain knowledge and education along with improving practical experience. Here, we demonstrate the introduction of a flipped classroom curriculum for practical courses in Otorhinolaryngology (ORL) in real world practice to improve the on-site time management and students’ experience.
Methods
Educational aims of our practical curriculum were analysed and rearranged into a flipped classroom (FC) framework. Core knowledge was taught preliminary based on a moodle platform in predominantly interactive formats. Two quasi-randomized groups were formed with 212 participants either receiving or not receiving access to the e-learning program to reduce a potential allocation bias to the e-learning group. All students completed a questionnaire with learning related items. Focusing the study on the intervention group, we investigated if students using the flipped classroom more often felt better prepared for the practical course.
Results
The online learning platform was highly accepted and frequently used by 66% of participating students in the e-learning group. Students with frequent use of our e-learning platform significantly felt better prepared for the practical course (
p
= 0.001). The far majority of all students supports the idea of further development of e-learning. More than 70% were generally interested in ORL. Handouts were the overall most important learning resource and more than 50% relied solely on them.
Conclusions
Flipped classroom curricula can save time and help improving the on-site experience in practical courses especially in smaller surgical disciplines. The acceptance of digital learning is high, and most students rely on handouts for learning ORL, emphasizing the need for guidance by the teacher e.g. through electronic learning. Our results underline the high potential of FC to address teaching challenges for smaller medical disciplines with limited teaching time like ORL.
