Attitudes of Acutely Ill Patients Towards Euthanasia in Hong Kong
The global euthanasia debate by health care professionals has raised important ethical issues concerning the professional duties and responsibilities of nurses caring for terminal patients. The purpose of this study was to examine the attitudes of acutely ill patients towards the practice of euthanasia in Hong Kong. A modified form of the 23-item Questionnaire for General Household Survey scale was used. This cross-sectional survey study was conducted with a stratified sample of in-patients recruited from a wide variety of departments in a regional, acute general hospital. Seventy-seven out of 129 patients responded (59.7%) and a high proportion of patients agreed with the use of euthanasia in the following circumstances: âwhere they were a third partyâ, if âsomeone they lovedâ was affected, or if âthey themselves were the patientâ. Of the 77 patients, 54 agreed with active euthanasia (70.1%) and 65 with passive (84.4%). The results also indicated that a few socio-demographic characteristics (such as age, gender and household income) statistically significantly correlated with patientsâ attitudes towards euthanasia. These findings highlight that Chinese patients with acute illness generally accept the use of euthanasia. Further research on the attitudes and perceptions of patients towards the use of euthanasia is recommended, particularly in diverse groups of Chinese and Asian patients with acute or terminal illness
Bracketing in Phenomenology: Only Undertaken in the Data Collection and Analysis Process
Our aim with this article is to demonstrate how the researchers use bracketing as a method of demonstrating the validity after initiating a phenomenological study. Although bracketing is a method of demonstrating the validity of the da ta collection and analysis process in most phenomenological studies, how the researchers use them in practice is rarely demonstrated explicitly. We collected data through our experiences in preparing a phenomenological research study. We suggest that the concept of bracketing should be adopted upon initiating the research proposal and not merely in the data collection and analysis process. We propose four strategies for doing bracketing that are guided by the thinking activity of reflexivity: mentality assessment and preparation before deciding the research paradigm, deciding the scope of the literature review according to the prevailing gate - keeping policy, planning for data collection using semi - structured interviews guided by open - ended questions, and planning for data analysis using Colaizziâs method. Our proposition highlights that thorough preparation for doing bracketing is essential before entering the data collection and analysis process in phenomenology, because they are sequentially related
Is adherence therapy an effective adjunct treatment for patients with schizophrenia spectrum disorders? A systematic review and meta-analysis
Background Poor adherence to medication in schizophrenia spectrum disorders leads to inadequate symptom control. Adherence therapy (AT) is an intervention that seeks to reduce patientsâ psychiatric symptoms by enhancing treatment adherence. We aimed to systematically review the trial evidence of the effectiveness of AT on improving clinical outcomes in these patients. Method Systematic review and meta-analysis of published RCTs. We included studies testing AT as an adjunct intervention against treatment as usual or a comparator intervention in the general adult psychiatric population. The primary outcome of interest was improvement in psychiatric symptoms. Results We included six studies testing AT in schizophrenia spectrum disorders published since 2006. A meta-analysis showed AT significantly reduced psychiatric symptoms compared to usual treatment over a follow-up period of less than 1 year. We found no significant effects of AT on patientsâ adherence and adherence attitudes. Conclusions AT is an effective adjunctive treatment for people with schizophrenia spectrum disorders
Integrating SPC and EPC for Multivariate Autocorrelated Process
Statistical process control (SPC) is a widely employed quality control method in industry. SPC is mainly designed for monitoring single quality characteristic. However, as the design of a product/process becomes complex, a process usually has multiple quality characteristics related to it. These characteristics must be monitored by multivariate SPC. When the autocorrelation is present in the process data, the traditional SPC may mislead the results. Hence, the autocorrelated data must be treated to eliminate the autocorrelation effect before employing SPC to detect the assignable causes. Besides, chance causes also have impact on the processes. When the process is out of control but no assignable cause is found, it can be adjusted by employing engineering process control (EPC). However, only using EPC to adjust the process may make inappropriate adjustments due to external disturbances or assignable causes. This study presents an integrated SPC and EPC procedure for multivariate autocorrelated process. The SPC procedure constructs a predicting model using group method of data handling (GMDH), which can transfer the autocorrelated data into uncorrelated data. Then, the Hotellingâs T2 and multivariate cumulative sum control charts are constructed to monitor the process. The EPC procedure constructs a controller utilizing data mining technique to adjust the multiple quality characteristics to their target values. Industry can employ this procedure to monitor and adjust the multivariate autocorrelated process
Optical pulse-shaping for internal cooling of molecules
We consider the use of pulse-shaped broadband femtosecond lasers to optically
cool rotational and vibrational degrees of freedom of molecules. Since this
approach relies on cooling rotational and vibrational quanta by exciting an
electronic transition, it is most easily applicable to molecules with similar
ground and excited potential energy surfaces, such that the vibrational state
is usually unchanged during electronic relaxation. Compared with schemes that
cool rotations by exciting vibrations, this approach achieves internal cooling
on the orders-of- magnitude faster electronic decay timescale and is
potentially applicable to apolar molecules. For AlH+, a candidate species, a
rate-equation simulation indicates that rovibrational equilibrium should be
achievable in 8 \mu s. In addition, we report laboratory demonstration of
optical pulse shaping with sufficient resolution and power for rotational
cooling of AlH+
Translation and Validation of the Chinese ICD-11 International Trauma Questionnaire (ITQ) for the Assessment of Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD)
Background: Two stress-related disorders have been proposed for inclusion in the revised ICD-11: Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD). The International Trauma Questionnaire (ITQ) is a bespoke measure of PTSD and CPTSD and has been widely used in English-speaking countries. Objective: The primary aim of this study was to develop a Chinese version of the ITQ and assess its content, construct, and concurrent validity.
Methods: Six mental health practitioners and experts rated the Chinese translated and back-translated items to assess content validity. A sample of 423 Chinese young adults completed the ITQ, the WHO Adverse Childhood Experiences International Questionnaire, and the Hospital Anxiety and Depression Scale. Among them, 31 participants also completed the English and Chinese versions of the ITQ administered in random order at retest. Four alternative confirmatory factor analysis models were tested using data from participants who reported at least one adverse childhood experience (ACE; N = 314).
Results: The Chinese ITQ received excellent ratings on relevance and appropriateness. Testâretest reliability and semantic equivalence across English and Chinese versions were acceptable. The correlated first-order six-factor model and a second-order two-factor (PTSD and DSO) both provided an acceptable model fit. The six ITQ symptoms clusters were all significantly correlated with anxiety, depression, and the number of ACEs.
Conclusions: The Chinese ITQ generates scores with acceptable psychometric properties and provides evidence for including PTSD and CPTSD as separate diagnoses in ICD-11
Development of wireless bruxism monitoring device based on pressure-sensitive polymer composite
A wireless pressure sensing bite guard has been developed for monitoring the progress of bruxism (teeth grinding during sleep); as well as protecting the teeth from damages. For sensing the pressure effectively in the restricted space and hostile environment, a pressure sensitive polymer composite has been fabricated and encapsulated into a conventional bite guard which is safe for in-situ applications. The device is anticipated to give real-time data through wireless data transmission and to have a long working life (weeks). A microcontroller-based electronic circuit has been built in-house for data collection and transmission. A low power approach is configured to increase the working life of the device. This device is a useful tool for understanding and treating bruxism
Fabrication and Photovoltaic Characteristics of Coaxial Silicon Nanowire Solar Cells Prepared by Wet Chemical Etching
Nanostructured solar cells with coaxial p-n junction structures have strong potential to enhance the performances of the silicon-based solar cells. This study demonstrates a radial junction silicon nanowire (RJSNW) solar cell that was fabricated simply and at low cost using wet chemical etching. Experimental results reveal that the reflectance of the silicon nanowires (SNWs) declines as their length increases. The excellent light trapping was mainly associated with high aspect ratio of the SNW arrays. A conversion efficiency of âź7.1% and an external quantum efficiency of âź64.6% at 700ânm were demonstrated. Control of etching time and diffusion conditions holds great promise for the development of future RJSNW solar cells. Improving the electrode/RJSNW contact will promote the collection of carries in coaxial core-shell SNW array solar cells
