The Physics of the B Factories

This work is on the Physics of the B Factories. Part A of this book contains a brief description of the SLAC and KEK B Factories as well as their detectors, BaBar and Belle, and data taking related issues. Part B discusses tools and methods used by the experiments in order to obtain results. The results themselves can be found in Part C

Nutrient Intake During Peritoneal Dialysis at the Prince of Wales Hospital in Hong Kong

Background: Individuals undergoing peritoneal dialysis are at increased risk of developing cardiac disease and malnutrition. Study Design: A cross-sectional survey. Settings and Participants: 249 Chinese continuous ambulatory peritoneal dialysis (CAPD) patients were recruited from the Prince of Wales Hospital in Hong Kong. Another 249 age- and sex-matched controls were recruited from an archive of 1,010 individuals with known food frequency questionnaire (FFQ) data. Objective: To compare the dietary intake pattern of CAPD patients with controls and evaluate its association with background cardiac disease. Outcomes and Measurements: Intake of different nutrients was estimated by using a 7-day FFQ. Results: Intake of all nutrients was lower in CAPD patients than controls, with resulting lower overall energy intake. Nutrient intake was decreased further in CAPD patients with background cardiac disease, which corresponded to worse nutritional status. Controlling for age, male sex, body weight, diabetes mellitus, dialysis therapy duration, residual renal function, peritoneal dialysis urea clearance, and Charlson Comorbidity Index score, background cardiac disease was associated independently with less intake of energy and most macronutrients and micronutrients. However, the association between background cardiac disease and energy and most nutrient intake was decreased or even lost when additional adjustment was made for C-reactive protein and serum albumin levels. Limitations: An FFQ is limited in that nutrient quantitation is not exact and may be underestimated as a result of underreporting by patients. CAPD patients were compared with a control group without cardiovascular disease ascertainment that did not include subjects with diabetes. Conclusions: Chinese CAPD patients had significantly lower nutrient intake than age- and sex-matched controls. The association between cardiac disease and lower dietary macronutrient and micronutrient intake in CAPD patients was mediated in part through systemic inflammation, which also was associated with more malnutrition. More attention should be focused on improving the intake pattern of Chinese CAPD patients. © 2007 National Kidney Foundation, Inc.Link_to_subscribed_fulltex

Self-competence in death work among health and social care workers: a region-wide survey in Hong Kong

Abstract Background According to the Quality of Death Index, Hong Kong is lagging behind many other Western and Asian countries in the category of palliative and healthcare. To ensure the provision of high-quality palliative care, it is important to explore the self-competence of health and social care workers in coping with death work including palliative care. This region-wide study aims to assess the level of self-competence with a validated Self-Competence in Death Work Scale (SC-DWS) and examine its correlates. Methods The SC-DWS was administered to a cross-sectional convenience sample of health and social care workers across eight healthcare institutions between January and October 2016. Total scores for the 16-item SC-DWS and its Existential and Emotional subscales were calculated. We then examined sociodemographic variables (e.g., age, profession, place of employment) in relation to the total and subscale scores using multiple linear regression. Coding was conducted on responses to a final open-ended question asking about the personal views of the workers towards their self-competence in death work. Result We collected data from 885 health and social care workers. Mean score of the SC-DWS was 60.16 (range: 16 – 80), while its Existential and Emotional subscales scored 37.90 (range: 10 – 50) and 14.46 (range: 4 – 20) respectively. Four categories of personal view towards self-competence in death work including (1) personal resources; (2) existential challenges and coping; (3) emotional challenges and coping; and (4) personal recommendations on improving self-competence were identified. In multivariate analyses, workers aged 50 or above, divorced, working in Hospice A, Rehabilitation Hospital B (where a quality improvement initiative in end-of-life care was implemented) and Acute Hospital B (a Christian institution with strong caring culture) and with personal bereavement experience had significantly higher scores, whereas nurses scored significantly lower than less-educated personal care assistants. Conclusion There is still room for improvement in self-competence in death work among health and social care workers, particularly the young, nurses and those working in acute hospitals. Future initiatives should involve identifying barriers in individual healthcare institutions. Training of the provision of palliative care is necessary

Constitutional Conflict in Hong Kong Under Chinese Sovereignty

© 2016, T.M.C. Asser Press.The protracted constitutional conflicts between the Chinese state and Hong Kong society over the pace and form of democratization have become a source of political instability. This article sheds new light on these dynamics by analyzing the two sides as locked in a coordination dilemma: both have important common interests to coordinate with each other, but both rank in divergent ways their preferences for and against introducing competitive electoral arrangements into Hong Kong. It is shown how the unwillingness of either side to compromise has caused the gradual breakdown of coordination as focal points like the Basic Law have eroded, culminating in the Umbrella Revolution of 2014, the largest and longest-lasting popular movement in Hong Kong history. The bloodless ending of the Movement is chronicled, along with the persistence of political stalemate in this highly anomalous polity, known throughout the world for its combination of genuine civil liberties with authoritarian rule.Link_to_subscribed_fulltex
