Since their inception, social networking sites (SNSs) have experienced exponential growth. While substantial research has been dedicated to users’ initial adoption of SNSs, the fall of MySpace reminds us that the long-term success of SNSs depends on users’ post adoption staying power. Inspired by this, this work-in-progress investigates users’ “stickiness” with a specific SNS. Based on Li et al...

This paper reports on an empirical investigation of the relationship between print and hypertext reading skills. Subjects in the study were university students at a public Midwestern university. A repeated-measures, counter-balanced design was employed. Subjects were categorized as highand low-ability readers based on a standardized measure of reading achievement. Experimental tasks required su...

Content contribution from individuals is critical to the viability of online communities. In this study we identify the factors that are associated with the quantity and the quality of content sharing in a photo sharing community, where the act of content creation is decoupled from the act of content sharing. We draw on theories of intrinsic and extrinsic motivation, and find that the prospect ...

Abstract Background Ulcerative Colitis (UC) combine both inflammation and coagulation in their pathogenesis clinical manifestations. Although platelets (PLT) are well known for role hemostasis, there a rising number of studies supporting considerable as inflammatory amplifiers chronic conditions. However, whether PLT related to the efficacy biologic agents is unknown. This study aimed investiga...

This study assessed the production and categorial discrimination of English / / and / / by native Korean (NK) adults and children. A total of 108 participants (72 NK and 36 age-matched native English speakers) were tested twice. The NK participants were further subdivided according to length of residence (LOR) in North America. In Experiment 1, both the NK adults and NK children differed from a...

BACKGROUND The plasma effect-site equilibrium rate constant (k(e0)) of propofol has been reported in various pharmacodynamic studies; however, it is not desirable to apply k(e0) for the link with pharmacokinetic models that were separately investigated. Thus, we titrated k(e0) for the pharmacokinetic model, which is known as the multiple covariates adjusted model of propofol. METHODS Ninety f...

PURPOSE We measured dynamic biomechanics of loss-of-resistance (LOR) epidural placement in prone cadavers, focussing on the period immediately following LOR, to estimate forces acting on the tissue of the epidural space. METHODS An epidural syringe with 17G Hustead needle was instrumented to track force on the plunger, pressure in the chamber, and movement of barrel and plunger. Insertions we...

OBJECTIVES Neutrophil-to-lymphocyte ratio (NLR) has been used to determine the outcome in malignancies and coronary heart disease. Some reports considered the value of NLR as a predictor of response to infliximab in patients with Crohn's disease or rheumatoid arthritis; however, no similar studies have been reported for ulcerative colitis (UC). This study aimed to evaluate the clinical signific...

This paper addresses the problem of the evaluation of people counting systems. The relation between the real people number and the output of the people counting system is used to motivate the computation of the maximum number of people as a scenario and geometry specific quantity which supports the evaluation of the system output. Based on the camera field-of-view we determine the maximum numbe...
