Silent or subclinical asymptomatic atrial fibrillation (SAF) has currently gained wide interest in the epidemiologic, neurologic, and cardiovascular communities. It is well known that the ...electrophysiological and mechanical effects of symptomatic and silent atrial fibrillation (AF) are the same. It is probable that because “AF begets AF,” progression from paroxysmal to persistent or permanent AF might be more rapid in patients with long‐term unrecognized and untreated SAF, because no treatment is sought by or provided to such patients. Moreover, SAF is common and has significant clinical implications. The clinical consequences of SAF, which include emboli (silent or symptomatic), heart failure, and early mortality, are of paramount importance. Consequently, SAF should be considered in estimating the prevalence of the disease and its impact on morbidity, mortality, and quality of life. Several diagnostic methods of arrhythmia detection utilizing the surface electrocardiogram (ECG), subcutaneous ECG, or intracardiac devices have been utilized to seek meaningful arrhythmic markers of SAF. Whereas a wide range of clinical risk factors of SAF have been validated in the literature, there is an ongoing search for those arrhythmic risk factors that precisely identify and prognosticate outcome events in diverse populations at risk of SAF. Modern diagnostic modalities for the identification of SAF exist, but should be further explored, validated, and tailored to each patient needs. The scientific community should undertake the clinical challenge of identifying and treating SAF.
Loneliness is understood as a painful negative emotion. Since its introduction into the psychiatric literature in 1959, the understanding of loneliness has improved considerably, and is now ...understood to be a distinct entity to such issues as social isolation, solitude, and depression. However, there is still a lack of consensus on the general definition of loneliness. Similarly, different dimensions of loneliness have been described in the literature. It is understood in terms of either transient versus situational versus chronic loneliness; state versus trait loneliness; and the concept of unidimensional versus multidimensional loneliness. The reported prevalence of loneliness varies considerably in the literature, with evidence from metanalysis suggesting the prevalence of moderate loneliness that ranges from 31 to 100% with a mean of 61%, and that of severe loneliness ranging from 9 to 81%, with a mean prevalence of 35% among the elderly. Loneliness among the elderly is associated with significant adverse mental and physical health outcomes in the form of cardiovascular diseases, stroke, diabetes mellitus, arthritis, depression, anxiety, dementia, and even problematic internet use. Over the years, different instruments University of California Los Angeles Loneliness Scale (UCLA-LS), De Jong Gierveld Loneliness Scale, Single-Item direct measure of loneliness have been designed to assess loneliness among the elderly. Some of the interventions suggest that persons experiencing loneliness could benefit from improved social skills, enhanced social support, increased opportunities for social contact, and addressing maladaptive social cognition.
•We compare the complexity, novelty and impact of green vs. non-green technologies.•Green patents combine more technological components, rely on more diverse sources and novel combinations of ...knowledge.•Green technologies have a larger and more pervasive impact on future inventions.•Complexity and novelty partially explain the larger spillovers of green technologies.•Results support the implementation of policies targeting green technologies (that are also complex and novel).
The paper investigates the nature and impact of green technological change. We focus on the search and impact spaces of green inventions: we explore the knowledge recombination processes leading to the generation of inventions and their impact on subsequent technological developments. Using a large sample of patents, filed during the period 1980-2012, we employ established patent indicators to capture the complexity, novelty and impact of the invention process. Technological heterogeneity is controlled for by comparing green and non-green technologies within narrow technological domains. We find that green technologies are more complex and appear to be more novel than non-green technologies. In addition, they have a larger and more pervasive impact on subsequent inventions. The larger spillovers of green technologies are explained only partially by novelty and complexity.
Simultaneous alcohol and marijuana (SAM) use is prevalent among young adult drinkers and associated with increased risk for harms. Less understood about SAM use is whether increased risk is incurred ...on SAM use occasions relative to occasions in which individuals used only 1 substance. From a sample of young adult SAM users, we compared occasions in which individuals simultaneously used alcohol and marijuana so that the effects overlapped ("SAM days"), occasions involving only alcohol ("alcohol days"), and occasions involving only marijuana ("marijuana days") on level of use, level of subjective intoxication, and negative and positive consequences. Eligible participants (N = 154; 57.8% female, 72.7% non-Hispanic/Latinx White) were 18-25 years old, reported past-month SAM use, and reported past 2-week binge drinking. Participants completed up to 14 daily assessments on their substance use behavior. Multilevel models indicated that, relative to alcohol days, SAM days had more negative consequences. SAM and alcohol days were not statistically different on level of use, level of subjective alcohol intoxication, or positive consequences. Relative to marijuana days, SAM days had more negative consequences and more positive consequences. Level of use (number of hits) and level of marijuana intoxication were not statistically different. In addition to SAM users being a more at-risk group, SAM occasions are associated with greater risk within this vulnerable population. Fine-grained ecological momentary assessments are needed to better understand perceptions and behavior throughout a SAM use episode.
Given the dynamic nature of digital technologies, understanding why users intend to continue to use them or not is important for practitioners and academics alike. This paper presents an up-to-date ...Systematic Literature Review (SLR) of Continuance Intention (CI) for online technologies. The SLR classifies and analyses 147 relevant articles on CI in the field of online technology. It analyses papers according to the type of online technology as well as four groups of antecedents (psychological, technological, social, and behavioral) of CI and reviews the consequences of CI. Based on the SLR, the paper outlines two broad directions for future research relating to a conceptual framework and research design, highlighting promising research areas linked to the new features of emerging technologies, such as hyper-connectivity, and intention-behavior gaps.
Blockchain technology has gained global attention with potential to revolutionize supply chain management and sustainability achievements. The few applied ongoing use cases include blockchain for ...food, healthcare, and logistics supply chains have emphasized blockchain's untapped potential. Potential support for supply chain and sustainability issues include improving efficiency, transparency, and traceability in addition to billions of dollars in corporate financial savings. Given its promise, the adoption of blockchain technology, although hyped for years, has not seen rapid acceptance. In this study, the technology-organization-environment framework and force field theories are utilized to investigate blockchain adoption barriers. Using various literature streams on technology, organizational practices, and sustainability, a comprehensive overview of barriers for adopting blockchain technology to manage sustainable supply chains is provided. The barriers are explored using technology, organizational, and environmental – supply chain and external – framework followed by inputs from academics and industry experts and then analyzed using the Decision-Making Trial and Evaluation Laboratory (DEMATEL) tool. The results show that supply chain and technological barriers are the most critical barriers among both academics and industry experts. We further determine the similarities and differences among academics and practitioners in perceiving the barriers. This exploratory study reveals interesting relative importance and interrelationships of barriers which are necessary, theoretically and practically for further adoption and dissemination of blockchain technology in a sustainable supply chain environment. It also sets the stage for theoretical observations for understanding blockchain technology implementation in sustainable supply chains. A series of research propositions and research directions culminate from this exploratory study.
•Blockchain adoption barriers for sustainable supply chain management are examined.•Technology-Organization-Environment framework and force field theories inform study.•Technology barriers dominate blockchain and sustainable supply chain barriers.•Academic and practitioner perspectives are evaluated.•Research propositions provide guidance for further investigation.
What are the positive and negative consequences of telecommuting? How do these consequences come about? When are these consequences more or less potent? The authors answer these questions through ...construction of a theoretical framework and meta-analysis of 46 studies in natural settings involving 12,883 employees. Telecommuting had small but mainly beneficial effects on proximal outcomes, such as perceived autonomy and (lower) work-family conflict. Importantly, telecommuting had no generally detrimental effects on the quality of workplace relationships. Telecommuting also had beneficial effects on more distal outcomes, such as job satisfaction, performance, turnover intent, and role stress. These beneficial consequences appeared to be at least partially mediated by perceived autonomy. Also, high-intensity telecommuting (more than 2.5 days a week) accentuated telecommuting's beneficial effects on work-family conflict but harmed relationships with coworkers. Results provide building blocks for a more complete theoretical and practical treatment of telecommuting.
This paper studies whether, in the consumer credit market, peer-to-peer (P2P) lending platforms serve as substitutes for banks or instead as complements. I develop a conceptual framework and derive ...testable predictions to distinguish between these two possibilities. Using a regulatory change as an exogenous shock to bank credit supply, I find that P2P lending is a substitute for bank lending in terms of serving infra-marginal bank borrowers yet complements bank lending with respect to small loans. These results indicate that the credit expansion resulting from P2P lending likely occurs only among borrowers who already have access to bank credit.
Abstract

The COVID-19 pandemic not only dominates the media, but is the subject of numerous linguistic comments and scientific articles ...discussing the linguistic consequences of the health crisis (the emergence of new meanings and words or the penetration of specialized terms in everyday language).
•Sensation seeking (but not lack of premeditation) was associated with co-use.•Drinking quantity mediated the effect of co-use on negative consequences.•Positive expectancies also mediated the effect ...of co-use on negative consequences.•Lack of premeditation predicted positive expectancies above and beyond co-use.•Personalized interventions should focus on distinct impulsive personality traits.
Alcohol and cannabis co-users experience more negative alcohol consequences, but distal and mediating mechanisms of this association remain largely unstudied. Considering research suggests that individuals high in impulsivity and sensation seeking are more likely to be co-users, it is possible that co-users have more positive expectancies and become heavier drinkers, which confer risk for future negative consequences. Therefore, the current study tested prospective mediation models in which impulsive personality traits indirectly predicted negative consequences through co-use, heavier drinking, and expectancies.
The current study used data from a study of familial AUD spanning 3 waves (1995–2010). Participants (N = 567) reported on impulsivity (via the Eysenck Personality Inventory and Sensation Seeking Scale) alcohol and cannabis use, alcohol expectancies, and negative consequences. Models tested the factor structure of impulsive personality traits and whether these traits predicted future negative consequences through past-year co-use and drinking/expectancies.
Factor analysis suggested two factors, sensation seeking and lack of premeditation. Sensation seeking was associated with future negative consequences indirectly through co-use and both drinking quantity and positive expectancies. Lack of premeditation was not associated with co-use, but indirectly predicted negative consequences through positive expectancies, above and beyond co-use. Sensation seeking directly predicted negative expectancies, but negative expectancies did not predict negative consequences.
Impulsive personality traits in co-users, particularly sensation seeking, explained variance in future negative alcohol consequences via heavier drinking (behavior) and positive expectancies (cognition). Personalized interventions targeting a lack of premeditation, and sensation seeking in co-users, may interrupt a developmental trajectory toward problem drinking.
