Do Reduced Hospital Mortality Rates Lead to Increased Utilization of Inpatient Emergency Care?:A Population-Based Cohort Study
2018
OBJECTIVES: To measure the impact of the improvement in hospital survival rates on patients' subsequent utilization of unplanned (emergency) admissions.DATA SOURCES/STUDY SETTING: Unplanned admissions occurring in all acute hospitals of the National Health Service in England between 2000 and 2009, including 286,027 hip fractures, 375,880 AMI, 387,761 strokes, and 9,966,246 any cause admissions.STUDY DESIGN: Population-based retrospective cohort study. Unplanned admissions experienced by patients within 28 days, 1 year, and 2 years of discharge from the index admission are modeled as a function of hospital risk-adjusted survival rates using patient-level probit and negative binomial models. …
The profiles of health care utilization among a non-depressed population and patients with depressive symptoms with and without clinical depression
2019
Objective: To examine health service (HS) utilization profiles among a non-depressive population and patients with depressive symptoms (DS) with and without clinical depression. Design, subjects and setting: The study population was based on primary care patients with DS scoring ≥10 in the 21-item Beck Depression Inventory (BDI) and who were at least 35 years old and had been referred to depression nurse case managers (n = 705). Their psychiatric diagnosis was confirmed with the Mini-International Neuropsychiatric Interview (M.I.N.I.). Of these patients, 447 had clinical depression. The number of patients with DS without clinical depression was 258. The control group consisted of a random s…
Bayesian forecasting with the Holt–Winters model
2010
Exponential smoothing methods are widely used as forecasting techniques in inventory systems and business planning, where reliable prediction intervals are also required for a large number of series. This paper describes a Bayesian forecasting approach based on the Holt–Winters model, which allows obtaining accurate prediction intervals. We show how to build them incorporating the uncertainty due to the smoothing unknowns using a linear heteroscedastic model. That linear formulation simplifies obtaining the posterior distribution on the unknowns; a random sample from such posterior, which is not analytical, is provided using an acceptance sampling procedure and a Monte Carlo approach gives …
The role of the brand in driving online loyalty for multichannel retailers
2015
Multichannel retailers offer shoppers the possibility to cross channels to complete their shopping process. Multichannel retailers, unlike pure online sellers, offer shoppers multiple contact points to experience the brand. Also, multichannel retailers can leverage the trust and attachment to their brands that has been built with their offline presence to drive customers to buy online. Our paper explores the role of the customer relationship with the brand, with variables such as brand trust, brand attachment and length of brand relationship, as drivers of loyal behaviours towards the online channel. We compare the impact of these variables with those of the technology acceptance model. Mul…
Intentions to use mobile services: Antecedents and cross-service comparisons
2005
- This article develops and tests a model to explain consumers' intention to use mobile services. Through triangulating theories from the diverse fields of information systems research, uses and gratification research, and domestication research, the authors put forth an integrated model that explains intention to use mobile services. The model proposes four overall influences on usage intention: motivational influences, attitudinal influences, normative pressure, and perceived control. The authors study the type of interactivity and process characteristics associated with the service that moderate the effects on the relationship between the proposed antecedents and usage intention. The res…
Mobile banking services adoption in Pakistan: are there gender differences?
2017
Purpose The purpose of this paper is to provide a comprehensive insight into the deciding factors affecting an individual’s intention to adopt mobile banking (m-banking) services in Pakistan. Design/methodology/approach A survey approach was used with a sample of 189 responses from across Pakistan. Multi-group analysis was performed in order to detect gender differences among men and women in the process of adopting m-banking. Findings The paper found support for the positive effect of perceived behavioral control (PBC) and attitudes (ATT) toward m-banking adoption intentions. Significant differences between men and women were found to affect subjective norms (SN) on adoption intention, ev…
Explaining consumer acceptance of mobile competitions and prize draws
2011
This article aims to develop an improved model for consumer acceptance of mobile competitions and prize draws announced on television programmes. Findings obtained from a sample of 396 Spanish mobile shoppers show that SMS compatibility influences directly and positively perceived SMS ease of use, perceived usefulness and attitude towards participating in M-competitions and prize draws. SMS ease of use does not directly influence M-competitions and prize draws usage intention, however, it does activate perceived usefulness which influences future usage intention through attitude. Moreover, SMS compatibility has been revealed as an important antecedent of technology acceptance model’s belief…
In-process calibration of a non-destructive testing system used for in-process inspection of multi-pass welding
2020
Abstract In multi-pass welding, there is increasing motivation to move towards in-process defect detection to enable real-time repair; thus avoiding deposition of more layers over a defective weld pass. All defect detection techniques require a consistent and repeatable approach to calibration to ensure that measured defect sizing is accurate. Conventional approaches to calibration employ fixed test blocks with known defect sizes, however, this methodology can lead to incorrect sizing when considering complex geometries, materials with challenging microstructure, and the significant thermal gradients present in materials during the inter-pass inspection period. To circumvent these challenge…
<title>Miniaturized objective lens for a photoelectron emission microscope</title>
2000
Photoemission electron microscopy (PEEM) has turned out to be one of the most promising methods for surface analysis in the recent years. It is a full field imaging technique based on the emission of secondary electrons by far ultraviolet light or X-rays. The emission intensity of secondary electrons is critically dependent upon the acceptance angle of the incident radiation. However, the size of the microscope restricts this angle substantially. Miniaturizing the objective lens of the microscope reduces the restriction of the acceptance angle and improves the performance of the PEEM considerably. We report on the fabrication of a miniaturized objective lens containing the extraction electr…
Mechanisms of Smartphone Apps for Cigarette Smoking Cessation: Results of a Serial Mediation Model From the iCanQuit Randomized Trial
2021
Background Engagement with digital interventions is a well-known predictor of treatment outcomes, but this knowledge has had limited actionable value. Instead, learning why engagement with digital interventions impact treatment outcomes can lead to targeted improvements in their efficacy. Objective This study aimed to test a serial mediation model of an Acceptance and Commitment Therapy (ACT) smartphone intervention for smoking cessation. Methods In this randomized controlled trial, participants (N=2415) from 50 US states were assigned to the ACT-based smartphone intervention (iCanQuit) or comparison smartphone intervention (QuitGuide). Their engagement with the apps (primary measure: numb…
