“It's part of me”
This study examines how continuous glucose monitoring (CGM), a wearable medical device, and the lived experience of diabetes collectively reshape the self-construal of people with diabetes. Using "content-context diaries" combined with semi-structured interviews, the research explores how CGM shapes three interrelated dimensions of the self: the datafied individual self, the shared relational self, and the narrative collective self. These constru…
A Low-Fragmentation Global Vector Dataset for River and Lake Classification of Surface Water Bodies
Accurately classified surface water datasets are critical for hydrological modeling, environmental monitoring, and water resource management. Most large-scale datasets are raster-based, produced through pixel-level classification. Existing global vector datasets often struggle to capture small water bodies and maintain global consistency. Therefore, extracting vector features from Earth observation raster products and performing fine-grained clas…
Emotional Expressions and First Impression Formation in Social Media Profiles
This study conducted an online experiment with 384 participants to explore the mechanisms through which viewers form initial impressions of strangers based on their emotional self-disclosure in social media profiles. The findings revealed that positive emotional expressions fostered a higher degree of interpersonal liking and trust than negative emotional expressions. The relationship between emotional valence and interpersonal liking was partial…
First versus final impression formation
Purpose This study investigated the influence of inconsistent versus consistent emotional expressions (independent variables) in social media profiles on first and final impressions in terms of interpersonal liking and trust (dependent variables). Design/methodology/approach Consistency in emotional expressions was operationalized as the same or different valences across all emotional posts. A 2 (initial positive vs negative emotional expressions…
Effect of cultural distance on female body image
Nostalgia, Social Media, and Subjective Wellbeing
Drastic lifestyle changes due to the COVID-19 pandemic have caused many people to undergo nostalgic longing for the past. Drawing on the regulatory model of nostalgia, we built a research model to examine the dualistic effects of nostalgia on subjective wellbeing, using self-continuity as a mediator and social media use as a moderator. The findings from an online survey (N = 373) indicated that when nostalgia is associated with an enhanced sense …
Real-Time Prescription Benefit Tool Adoption Among US Hospitals
This cross-sectional study examines real-time prescription benefit tool adoption among US hospitals overall and by hospital and community characteristics
The bright and dark sides of social media use during Covid-19 lockdown
Antiretroviral Treatment Gaps and Adherence Among People with HIV in the U.S. Medicare Program
Approximately one-quarter of people with HIV (PWH) in the U.S. receive coverage through the Medicare program; however, no prior real-world study has examined antiretroviral therapy (ART) gaps and adherence and associated factors in this population. This retrospective cohort analysis used 2013-2018 national Medicare fee-for-service claims data to identify all PWH initiated on a new ART regimen including protease inhibitors [PI], non-nucleoside rev…
From context adaptation to context restoration
Context collapse occurs on social media platforms when different groups are mixed into one audience. To advance the understanding of the extensive and complex coping strategies people use to address context collapse, this study makes a conceptual distinction between passively adapting by sharing context-free, general information (context adaptation) and rebuilding contexts to satisfy the diverse needs of impression management (context restoration…
Evaluation of Drifting Snow Susceptibility Based on GIS and GA-BP Algorithms
Drifting snow, the flow of dispersed snow particles near ground level under the action of wind, is a major form of snow damage. When drifting snow occurs on railways, highways, and other transportation lines, it seriously affects their operational safety and results in drifting snow disasters. Drifting snow disasters frequently occur in the high latitudes of northwest China. At present, most scholars are committed to studying the prevention and c…
Assessment of US Pharmacies Contracted With Health Care Institutions Under the 340B Drug Pricing Program by Neighborhood Socioeconomic Characteristics
This cross-sectional study assesses pharmacy participation in the 340B Drug Pricing Program following the 2010 expansion and the extent to which growth has occurred in socioeconomically disadvantaged neighborhoods
MeToo as a Connective Movement
This study was aimed to contribute to understanding how networked yet fragmented online actors create meaning in digital media–enabled movements like #MeToo. By drawing upon a multidimensional framing analysis, this study investigated how personal action frames, collective action frames, and issue-specific frames were adopted in #MeToo movement in China, and it also shed light on how different groups of social actors respond to sexual harassment …
Factors Associated with Iowa Rural Hospitals' Decision to Convert to Critical Access Hospital Status
Context: The Balanced Budget Act (BBA) of 1997 allowed some rural hospitals meeting certain requirements to convert to Critical Access Hospitals (CAHs) and changed their Medicare reimbursement from prospective to cost‐based. Some subsequent CAH‐related laws reduced restrictions and increased payments, and the number of CAHs grew rapidly. Purpose: To examine factors related to hospitals' decisions to convert and time to CAH conversion. Methods: Ei…
Converting to Critical Access Status
To improve rural access to care, the Balanced Budget Act of 1997 allowed eligible rural hospitals to convert to critical access hospitals (CAHs), which changed their Medicare payment from a prospective payment system (PPS) to a cost-based system. The objective of this paper is to examine the effects of CAH conversion on rural hospital operating revenues, operating expenses, and operating margins using an eight-year panel of 89 rural hospitals in …
Effects of Specialty Hospitals on the Financial Performance of General Hospitals, 1997–2004
Hospital specialization has become a controversial topic, culminating in a moratorium issued in 2003 by Congress directing the Centers for Medicare and Medicaid Services to cease payments to new physician-owned specialty hospitals for those Medicare and Medicaid patients referred by physicians with a financial interest in the facility. This paper focuses on one important economic question: does the presence of specialty hospitals in a market affe…
