The purpose of this paper is to examine the relationship of immediate workspace satisfaction (IWS) and environmental workplace quality (EWQ) on perceived organizational support (POS), engagement and organizational citizenship behaviors (OCBs). In this paper, we draw on social exchange theory and environmental psychology to propose IWS and EWQ as drivers of employee OCBs.,A survey was conducted with 1,206 full-time employees. The EWQ measure was assessed with a randomly selected calibration sampl...

Business writers and academics have suggested keeping an investing diary to avoid hindsight bias. In the diary, investors justify their predictions of future events, e.g., “This stock will go up because…” Eliminating hindsight bias should improve future returns. However, psychological research on the “explanation effect” suggests that justifying one’s predictions in writing induces overconfidence and, by consequence, reduces current returns. We test these propositions in a set of prediction mark...

ABSTRACT Objective To determine whether selection of treatment modality for urinary stone disease differs between primary and outreach healthcare centers, and if patient rurality predicts treatment modality. Methods We retrospectively evaluated ESWL and URS procedural data from the Iowa Office of Statewide Clinical Education Programs (OSCEP) and Iowa Hospital Association (IHA) databases from 2007-2014. Geographical data was used to analyze travel metrics and patient proximity to sites of stone t...

ABSTRACT OBJECTIVE To identify factors associated with nonmuscle invasive bladder cancer (NMIBC) American Urological Association (AUA) guideline compliance in a rural state, to evaluate compliance rates over time, and to assess the impact of patient and provider rurality on delivery of NMIBC care. METHODS We identified 847 Iowans in Surveillance, Epidemiology, and End Results-Medicare from 1992 to 2009 with high-grade NMIBC who survived 2 years and were not treated with cystectomy or radiation d...

Background Physician assistants are expected to have an important role in providing both primary and specialty care. Iowa has a large rural (and aging) population and faces challenges to provide equitable access to care. This study examined changes in the Iowa physician assistant workforce (1995–2015) focusing on practice setting (primary v. subspecialty care) and geographic location (rural/urban, Health Professional Shortage Area). Documenting their current locations and service in HPSAs for pr...

We examine variations in the relation between a hospital's level of service capability and the operating costs of its departments and activities (e.g., surgery, laboratory, laundry). We propose a model of the hospital as a set of concentric, interrelated services organized around a core mission to provide patient care. We hypothesize that increases in service capability (i.e., complexity of operations) will increase overall operating costs. At the departmental level, we expect variations in serv...
