    This study investigates the moderating effect of different types of Internet use regarding the relationship between three transitional aging changes and self-esteem of older adults. The current paper is still in progress; this is a research-in-progress paper. An aging population increases government expenditures and family responsibilities, thus drawing more attention from the academic community. Recent research posits that self-esteem tends to decline in individuals from the ages around 50-65 due to role loss, social loss, and dissatisfaction resulting from unaccomplished life goals. To address this issue, previous studies considered that the general use of the Internet may help to enhance self-esteem among older adults. To fill this research gap, the present study proposes that the cultural use of the Internet could moderate role loss of older adults, while social use of the Internet could mitigate social loss. Furthermore, economic use could moderate the dissatisfaction of unfulfilled life goals. Regarding various theoretical contributions, this is the first study to apply different types of Internet use, so as to investigate its moderating effect concerning the relationship between transitional aging changes and self-esteem. Findings of the present study can also help shed light on interventions for the caregiver in both community centers and the domestic environment to moderate the decline of self-esteem among older adults. The data will be collected through surveys distributed to District Elderly Community Centers (DECCs) in Hong Kong. Multiple regression analysis will then be utilized to test the moderating effect of each type of Internet use

    © 2017 The Author(s). Background: Breast cancer is the leading cause of cancer morbidity among Shanghai and Hong Kong women, which contributes to 20-25% of new female cancer incidents. This study aimed to describe the temporal trend of breast cancer and interpret the potential effects on the observed secular trends. Methods: Cancer incident data were obtained from the cancer registries. Age-standardized incidence rate was computed by the direct method using the World population of 2000. Average annual percentage change (AAPC) in incidence rate was estimated by the Joinpoint regression. Age, period and cohort effects were assessed by using a log-linear model with Poisson regression. Results: During 1976-2009, an increasing trend of breast cancer incidence was observed, with an AAPC of 1.73 [95% confidence interval (CI): 1.54-1.92)] for women in Hong Kong and 2.83 (95% CI, 2.26-3.40) in Shanghai. Greater upward trends were revealed in Shanghai women aged 50 years old or above (AAPC = 3.09; 95% CI, 1.48-4.73). Using age at 50 years old as cut-point, strong birth cohort effects were shown in both pre- and post-menopausal women, though a more remarkable effect was suggested in Shanghai post-menopausal women. No evidence for a period effect was indicated. Conclusions: Incidence rate of breast cancer has been more speedy in Shanghai post-menopausal women than that of the Hong Kong women over the past 30 years. Decreased birth rate and increasing environmental exposures (e.g., light-at-night) over successive generations may have constituted major impacts on the birth cohort effects, especially for the post-menopausal breast cancer; further analytic studies are warranted.Link_to_subscribed_fulltex

    A Study of Knowledge-Based Simulation for Enterprise Resources Planning

    The conventional way of using the Enterprise Resources Planning (ERP) applications is inadequate for the highly dynamic, complex and demanding business environment. The efficient use of the ERP system relies heavily on the know-how, experience and quality of the users. Since the knowledge of operating ERP system is difficult to be acquired, shared and diffused among the users, it takes time and money to train well-experienced users. As a result, this paper presents a framework of Knowledge-based Simulation System for Enterprise Resources Planning named KBSimERP. The KBSimERP provides an integrated learning environment for achieving three perspectives, which includes the knowledge acquisition, knowledge diffusion and performance measurement perspectives respectively. Hence, a prototype of the KBSimERP is built for production planning and control, and the performance of the system is preliminarily evaluated. Satisfactory results are obtained.Artificial intelligence, enterprise resources planning, knowledge management, simulation, multi-perspective

    Synergy Effect of Cyber-life-interruption and Cyberloafing on Employee Emotional Exhaustion

    Mobile Communication Technology (MCT) enables employee to maintain constant connectivity to work, as well as, allows them to take cyber breaks from work. Prior research dominantly emphasizes on the dark sides of cyber-life-interruption, i.e. working during non-working hours using MCT, and cyberloafing, i.e. doing nonworkrelated activities during working hours using MCT. Studying these two activities on the same dimension is rare too. This research-in-progress study examines the bright sides of cyber-life-interruption and cyberloafing, and their synergy effects to tackle employee emotional problems. It, draws on role theory and attribution theory, investigates the direct effects of cyber-life-interruption and cyberloafing on work and nonwork emotional exhaustion, respectively. It also, draws on conservation of resources theory, considers the interaction between cyber-life-interruption and cyberloafing as a stress management tool. It also extends research on behavioral intervention technologies. A quantitative survey was conducted, data analysis results would be presented in the conference

    Oxygen sensors prepared from tetramethyl orthosilicate and dimethoxy dimethylsilane with tris(4,7-diphenyl-1,10-phenanthroline)ruthenium (II) as the sensing dye were coated onto the well bottom surface of a 96-well polystyrene microtiter plate to give a high-throughput system for dissolved oxygen measurement. The oxygen sensors give linear Stern-Volmer calibration plots, and produce reliable and reproducible results in the determination Of IC50 values of drugs on a yeast model.

    High Accuracy Localization of Long Term Evolution Based on a New Multiple Carrier Noise Model

    No full text
    A high accuracy localization technique using Long Term Evolution (LTE) based on a new and accurate multiple carrier noise model has been developed. In the noise consideration, the LTE multiple carriers phase noise has been incorporated so that a new and accurate noise model is achieved. An experiment was performed to characterize the phase noise of carriers at 2 GHz. The developed noise model was incorporated into LTE localization analysis in a high traffic area in Hong Kong to evaluate the accuracy of localization. The evaluation and analysis reveals that the new localization method achieves an improvement of about 10% accuracy comparing to existing widely adopted schemes

    Obstructive uropathy in two Chinese patients with lupus interstitial cystitis

    AbstractWe report herein two patients who presented with bilateral hydronephrosis attributed to lupus cystitis with two totally different clinical consequences. Both had systemic lupus erythematosus complicated with nephritis and nephrotic range of proteinuria. During the investigation of their proteinuria, they were noted to have a dilated collecting system. The site of obstruction was localized at the vesicoureteric obstruction by excretory urogram. The hydronephrosis resolved spontaneously in one patient before the commencement of any medical therapy, whereas in the other patient, there was no response to steroid therapy. Augmentation enterocystoplasty was thus performed. Reversible hydronephrosis caused by vesicoureteric junction obstruction in patients with systemic lupus erythematosus has been reported. Immune-mediated vasculitis involving the ureter and bladder mucosa was the postulated pathogenic mechanism. The condition usually showed good clinical response upon immunosuppressive therapy. We conclude that systemic lupus erythematosus-associated interstitial cystitis can have a spectrum of different prognoses
