OBJECTIVE To investigate the sampling distribution and usefulness of expectation of life in comparisons of mortality at health district level or below. DESIGN Derivation of a formula for the variance of the expectation of life, confirmation of the result and generation of the sampling distribution by Monte Carlo simulation; comparison of expectation of life with standardised mortality ratio (...

automatic segmentation of multiple sclerosis (ms) lesions in brain magnetic resonance imaging (mri) has been widely investigated in the recent years with the goal of helping ms diagnosis and patient follow‑up. in this research work, gaussian mixture model (gmm) has been used to segment the ms lesions in mris, including t1‑weighted (t1‑w), t2‑w, and t2‑fluid attenuation inversion recovery. usual...

Building upon expectation confirmation theory and elaboration likelihood model, this study proposed and empirically tested a research model of user satisfaction with virtual social community. An online questionnaire was posted in the Bulletin Board Systems of a local university in Mainland China. A total of 240 online questionnaires were collected, and the data was analyzed using partial least ...

Interest in mobile short-video platforms (MSVP) as a new social network service tool has surged recent years. However, only few studies have focused on MSVP users’ post-acceptance behavior. To clarify this issue of sustainable usage, study analyzed habit formation by incorporating perceived interactivity and enjoyment into the expectation-confirmation theory information system continuance (ECT-...

Expectation-confirmation theory (ECT) posits that satisfaction is determined by interplay of prior expectations and perception of delivery. As such, there are many applications in research and practice that employ an ECT model. The descriptive power allows independent investigations manipulating either of the components and a format to examine just why clients are satisfied (or not) with a part...

Post adoption behaviours of e-service users are important for e-service providers to increase both their revenues and profits. This paper develops a model to investigate the factors influencing users’ post adoption behaviours, including continuance intention to use e-services and recommendation behaviour. The model is developed based on Expectation Confirmation Theory and includes two additiona...

After-sale service quality is a key to differentiating an online seller from numerous others and attracting returning customers. However, new customers cannot readily discern the quality of unfamiliar sellers. Sellers often try to reduce the information asymmetry and signal their quality by ensuring good website interface usability, considering that the website is the main point of contact with...

Benefit-cost integrated assessment models (BC-IAMs) inform climate policy debates by quantifying the trade-offs between alternative greenhouse gas abatement options. They achieve this by coupling simplified models of the climate system to models of the global economy and the costs and benefits of climate policy. Although these models have provided valuable qualitative insights into the sensitiv...
