Student Acceptance of Online Learning

The accelerated adoption of online learning during the COVID-19 pandemic provides an opportunity for the exploration of college student acceptance of online learning. We examine whether previous experience with online learning results in students’ greater acceptance of this modality as a valid educational experience. Findings are generated using original survey data from Park University undergraduate and graduate students. Our results have the potential to guide faculty and administrators regarding how online learning might be introduced and promoted, the pace at which their institution might adopt this modality, and the configuration of online learning that might work best for their students

Valuable Information and Costly Liquidity: Evidence from Individual Mutual Fund Trades

Until recently, all Canadian mutual funds were required to disclose all their individual trades, offering a unique and ideal opportunity to measure and analyze the cost and performance of mutual funds\u27 trades. We find that active management delivers both cheaper trades and better subsequent performance, and that the dissipative effect of flow-driven transactions costs is primarily through forced sales. Fund size associates with both cheaper trades and better subsequent performance, and a series of trades predicts more price movement in the predicted direction, indicating the value to funds of keeping their trading anonymous

Für mehr Gründerinnen in der Schweiz: Ansatzpunkte zur Verbesserung gründungsrelevanter Rahmenbedingungen

Mit der vorliegenden Studie, die quantitative und qualitative Daten berücksichtigt, möchten wir herausfinden, wie Expert*innen die gründungsbezogenen Rahmenbedingungen für Unternehmensgründungen durch Frauen einschätzen und inwiefern sie Unterschiede hinsichtlich der Rahmenbedingungen für Frauen im Vergleich zu Männern sehen. Anlass für die Studie ist die niedrigere Gründungsquote von Frauen. Gemäss des Global Entrepreneurship Monitors 2022 liegt die Gründungsquote von Frauen bei 7.2 %, jene der Männer bei 12.3 % (Baldegger, Gaudart & Wild, 2022). Bei innovations- und wachstumsbasierten Unternehmensgründungen sind die Unterschiede noch grösser. So sind beispielsweise nur knapp 7 % der im Swiss Start-up Radar aufgeführten Finanzierungsrunden von Unternehmen abgewickelt worden, die frauengeführt sind (Kyora & Rockinger, 2020)

Diffusing an Innovation: Clinician Perceptions of Continuous Predictive Analytics Monitoring in Intensive Care

Background The purpose of this article is to describe neonatal intensive care unit clinician perceptions of a continuous predictive analytics technology and how those perceptions influenced clinician adoption. Adopting and integrating new technology into care is notoriously slow and difficult; realizing expected gains remain a challenge. Methods Semistructured interviews from a cross-section of neonatal physicians (n ¼ 14) and nurses (n ¼ 8) from a single U.S. medical center were collected 18 months following the conclusion of the predictive monitoring technology randomized control trial. Following qualitative descriptive analysis, innovation attributes from Diffusion of Innovation Theory-guided thematic development. Results Results suggest that the combination of physical location as well as lack of integration into work flow or methods of using data in care decisionmaking may have delayed clinicians from routinely paying attention to the data. Once data were routinely collected, documented, and reported during patient rounds and patient handoffs, clinicians came to view data as another vital sign. Through clinicians’ observation of senior physicians and nurses, and ongoing dialogue about data trends and patient status, clinicians learned how to integrate these data in care decision making (e.g., differential diagnosis) and came to value the technology as beneficial to care delivery. Discussion The use of newly created predictive technologies that provide early warning of illness may require implementation strategies that acknowledge the risk–benefit of treatment cliniciansmust balance and take advantage of existing clinician trainingmethods

Identifying Distinct Risk Profiles to Predict Adverse Events among Community-Dwelling Older Adults

Preventing adverse events among chronically ill older adults living in the community is a national health priority. The purpose of this study was to generate distinct risk profiles and compare these profiles in time to: hospitalization, emergency department (ED) visit or death in 371 community-dwelling older adults enrolled in a Medicare demonstration project. Guided by the Behavioral Model of Health Service Use, a secondary analysis was conducted using Latent Class Analysis to generate the risk profiles with Kaplan Meier methodology and log rank statistics to compare risk profiles. The Vuong-Lo-Mendell-Rubin Likelihood Ratio Test demonstrated optimal fit for three risk profiles (High, Medium, and Low Risk). The High Risk profile had significantly shorter time to hospitalization, ED visit, and death (p \u3c 0.001 for each). These findings provide a road map for generating risk profiles that could enable more effective targeting of interventions and be instrumental in reducing health care costs for subgroups of chronically ill community-dwelling older adults

Physicians and Drug Representatives: Exploring the Dynamics of the Relationship

BACKGROUND: Interactions between physicians and drug representatives are common, even though research shows that physicians understand the conflict of interest between marketing and patient care. Little is known about how physicians resolve this contradiction. OBJECTIVE: To determine physicians’ techniques for managing cognitive inconsistencies within their relationships with drug representatives. DESIGN, SETTING, AND PARTICIPANTS: Six focus groups were conducted with 32 academic and community physicians in San Diego, Atlanta, and Chicago. MEASUREMENTS: Qualitative analysis of focus group transcripts to determine physicians’ attitudes towards conflict of interest and detailing, their beliefs about the quality of information conveyed and the impact on prescribing, and their resolution of the conflict between detailers’ desire to sell product and patient care. RESULTS: Physicians understood the concept of conflict of interest and applied it to relationships with detailers. However, they maintained favorable views of physician–detailer exchanges. Holding these mutually contradictory attitudes, physicians were in a position of cognitive dissonance. To resolve the dissonance, they used a variety of denials and rationalizations: They avoided thinking about the conflict of interest, they disagreed that industry relationships affected physician behavior, they denied responsibility for the problem, they enumerated techniques for remaining impartial, and they reasoned that meetings with detailers were educational and benefited patients. CONCLUSIONS: Although physicians understood the concept of conflict of interest, relationships with detailers set up psychological dynamics that influenced their reasoning. Our findings suggest that voluntary guidelines, like those proposed by most major medical societies, are inadequate. It may be that only the prohibition of physician–detailer interactions will be effective

Adaptations of Avian Flu Virus Are a Cause for Concern

We are in the midst of a revolutionary period in the life sciences. Technological capabilities have dramatically expanded, we have a much improved understanding of the complex biology of selected microorganisms, and we have a much improved ability to manipulate microbial genomes. With this has come unprecedented potential for better control of infectious diseases and significant societal benefit. However, there is also a growing risk that the same science will be deliberately misused and that the consequences could be catastrophic. Efforts to describe or define life-sciences research of particular concern have focused on the possibility that knowledge or products derived from such research, or new technologies, could be directly misapplied with a sufficiently broad scope to affect national or global security. Research that might greatly enhance the harm caused by microbial pathogens has been of special concern (1–3). Until now, these efforts have suffered from a lack of specificity and a paucity of concrete examples of “dual use research of concern” (3). Dual use is defined as research that could be used for good or bad purposes. We are now confronted by a potent, real-world example

Combined Forward-Backward Asymmetry Measurements in Top-Antitop Quark Production at the Tevatron

The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These measurements use the full data sets collected in proton-antiproton collisions at a center-of-mass energy of $\sqrt s =1.96$ TeV. We report the results of combinations of the inclusive asymmetries and their differential dependencies on relevant kinematic quantities. The combined inclusive asymmetry is $A_{\mathrm{FB}}^{t\bar{t}} = 0.128 \pm 0.025$. The combined inclusive and differential asymmetries are consistent with recent standard model predictions
