A THREE-YEAR LONGITUDINAL STUDY OF IN-CLASS SUSTAINED SILENT READING WITH TAIWANESE VOCATIONAL COLLEGE STUDENTS
This study examined the effects of three years of in-class sustained silent reading with a group of vocational college students in Taiwan. Readers outperformed comparisons on tests administered after one semester and increased their advantage on tests given at the end of the first year. The gap between the groups narrowed the second year, but readers maintained their superiority at the end of the second and third year. The initial gains were probably due, in part, to the Hawthorne Effect. It is likely that the progress made in the second and third year were more modest, because of external demands on studentsâ time, which limited the amount of reading students could do outside of class. Overall, the results clearly support the practice of in-school self-selected reading. Keywords:  In-class sustained silent reading; vocational college student; Hawthorne Effect; in-school self-selected readin

Storytelling research of consumers' self-reports of urban tourism experiences in China
[[abstract]]Using brand netnography (analyzing first-person on-line stories consumers tell that include discussions of their product and brand use), this article probes how visitors interpret the places, people, and situations that they experience while traveling in China (People's Republic of China). The visitors' reports focus on four greater metropolitan areas in China: Beijing, Lijiang, Shanghai, and Xi'an. Visitor stories interpreting these destinations support Robert McKee's wisdom that powerful storytelling moves people via unique "inciting incidents"-incidents serving to unfreeze or throw life out-of-balance. The visitors' destination lived-dramas give credence to Tom Peter's advocacy of focusing strategically on brand and Doug Holt's treatise on how brands become icons. The analysis includes applying Heider's balance theory in maps showing immediate and downstream positive and negative associations of concepts, events, and outcomes in visitors' stories. These maps include descriptions of how visitors experience specific Chinese destinations unique promises (i.e., distinct cultural history, minority way-of-life (Naxi society), China's Big Apple, China's origin, respectively for Beijing, Lijiang, Shanghai, and Xi'an). The article provides a revisionist proposal to Holt's five-step strategy for building destinations as iconic brands and suggestions for tourism management. (C) 2008 Elsevier Inc. All rights reserved

The relationship between web enjoyment and student perceptions and learning using a web-based tutorial
Web enjoyment has been regarded as a component of system experience. However, there has been little targeted research considering the role of web enjoyment alone in student learning using web-based systems. To address this gap, this study aims to examine the influence of web enjoyment on learning performance and perceptions by controlling system experience as a variable in the study. 74 students participated in the study, using a web-based tutorial covering subject matter in the area of 'Computation and algorithms'. Their learning performance was assessed with a pre-test and a post-test and their learning perceptions were evaluated with a questionnaire. The results indicated that there are positive relationships between the levels of web enjoyment and perceived usefulness and non-linear navigation for users with similar, significant levels of system experience. The implications of these findings in relation to web-based learning are explored and ways in which the needs of students who report different levels of web enjoyment might be met are discussed
Predicting adverse outcomes following catheter ablation treatment for atrial fibrillation
Objective: To develop prognostic survival models for predicting adverse
outcomes after catheter ablation treatment for non-valvular atrial fibrillation
(AF).
Methods: We used a linked dataset including hospital administrative data,
prescription medicine claims, emergency department presentations, and death
registrations of patients in New South Wales, Australia. The cohort included
patients who received catheter ablation for AF. Traditional and deep survival
models were trained to predict major bleeding events and a composite of heart
failure, stroke, cardiac arrest, and death.
Results: Out of a total of 3285 patients in the cohort, 177 (5.3%)
experienced the composite outcomeheart failure, stroke, cardiac arrest,
deathand 167 (5.1%) experienced major bleeding events after catheter ablation
treatment. Models predicting the composite outcome had high risk discrimination
accuracy, with the best model having a concordance index > 0.79 at the
evaluated time horizons. Models for predicting major bleeding events had poor
risk discrimination performance, with all models having a concordance index <
0.66. The most impactful features for the models predicting higher risk were
comorbidities indicative of poor health, older age, and therapies commonly used
in sicker patients to treat heart failure and AF.
Conclusions: Diagnosis and medication history did not contain sufficient
information for precise risk prediction of experiencing major bleeding events.
The models for predicting the composite outcome have the potential to enable
clinicians to identify and manage high-risk patients following catheter
ablation proactively. Future research is needed to validate the usefulness of
these models in clinical practice.Comment: Under journal revie
Smoking, passive smoking and histological types in lung cancer in Hong Kong Chinese women.
In a case control study in Hong Kong, 445 cases of Chinese female lung cancer patients all confirmed pathologically were compared with 445 Chinese female healthy neighbourhood controls matched for age. The predominant histological type was adenocarcinoma (47.2%). The relative risk (RR) in ever-smokers was 3.81 (P less than 0.001, 95% CI = 2.86, 5.08). The RRs were statistically significantly raised for all major cell types with significant trends between RR and amount of tobacco smoked daily. Among never smoking women, RR for passive smoking due to a smoking husband was 1.65 (P less than 0.01, 95% CI = 1.16, 2.35) with a significant trend between RR and amount smoked daily by the husband. When broken down by cell types, the numbers were substantial only for adenocarcinoma (RR = 2.12, P less than 0.01, 95% CI = 1.32, 3.39) with a significant trend between RR and amount smoked daily by the husband. The results suggest that passive smoking is a risk factor for lung cancer, particularly adenocarcinoma in Hong Kong Chinese women who never smoked
InGaN-based light-emitting diodes with an embedded conical air-voids structure
The conical air-void structure of an InGaN light-emitting diode (LEDs) was formed at the GaN/sapphire interface to increase the light extraction efficiency. The fabrication process of the conical air-void structure consisted of a dry process and a crystallographic wet etching process on an undoped GaN layer, followed by a re-growth process for the InGaN LED structure. A higher light output power (1.54 times) and a small divergent angle (120o) were observed, at a 20mA operation current, on the treated LED structure when compared to a standard LED without the conical air-void structure. In this electroluminescence spectrum, the emission intensity and the peak wavelength varied periodically by corresponding to the conical air-void patterns that were measured through a 100nm-optical-aperture fiber probe. The conical air-void structure reduced the compressed strain at the GaN/sapphire interface by inducing the wavelength blueshift phenomenon and the higher internal quantum efficiency of the photoluminescence spectra for the treated LED structure
Costs associated with febrile neutropenia in solid tumor and lymphoma patients - an observational study in Singapore.
BackgroundThe primary objective was to describe the total direct inpatient costs among solid tumor and lymphoma patients with chemotherapy-induced febrile neutropenia (FN) and the factors that were associated with higher direct cost. The secondary objective was to describe the out-of-pocket patient payments and the factors that were associated with higher out-of-pocket patient payments.MethodsThis was a single-center observational study conducted at the largest cancer center in Singapore. All of the adult cancer patients hospitalized due to FN from 2009 to 2012 were studied. The primary outcomes were the total hospital cost and the out-of-pocket patient payments (adjusted by government subsidy) per FN episode. Univariate analysis and multiple linear regression were conducted to identify the factors associated with higher FN costs.ResultsThree hundred and sixty seven adult cancer patients were documented with FN-related hospitalizations. The mean total hospital cost was US3,779-4,607) and the mean out-of-pocket patient payment was US1,976-2,484), per FN episode. The factors associated with a higher total hospital cost were longer length of stay, severe sepsis, and lymphoma as underlying cancer. The out-of-pocket patient payment was positively associated with longer length of stay, severe sepsis, lymphoma diagnosed as underlying cancer, the therapeutic use of granulocyte colony-stimulating factor (GCSF), the private ward class, and younger patients.ConclusionsThe total hospital cost and out-of-pocket patient payments of FN management in lymphoma cases were substantial compared with other solid tumors. Factors associated with a higher FN management cost may be useful for developing appropriate strategies to reduce the cost of FN for cancer patients
