A study of the universities of the third age in Hong Kong : an evaluation of elder academy model for the life long learning of older people

Education aims at the development of knowledge and skills for its own sake and pleasure. People aged over 65 years currently comprise 11% of the Hong Kong population. Such aging population in Hong Kong constitutes a challenge to our society. To be adaptive to changes in the environment, especially in aging, more emphasis is placed on “lifelong learning” than on “lifelong education” for self-fulfillment Active aging is evidently supported as a solution to the impact of aging population. Lifelong learning is an important strategy for enhancing active aging. The provision and process of lifelong learning for older people can take several forms. Of these, the best known is the University of the Third Age (U3A). However, in Hong Kong, the number of well-structured lifelong learning models is limited. Among various U3A models, the Australian model is more suitable in Hong Kong. In 2008, the Labour and Welfare Bureau and the Elderly Commission launched U3A, named as the Elder Academy (EA), with local characteristics that fit the Hong Kong context. Initially 32 EAs were established in Hong Kong. In consideration of the limited studies on the lifelong learning model for older people, the current study aims to evaluate the local EA model for lifelong learning for older people in Hong Kong. In the first phase of the macro level of evaluation, a documentary analysis was employed to examine various U3A models and 32 EA documents. Then, the in-depth interviews were conducted to obtain stakeholder perceptions on the local EAs. A total of 14 EA stakeholders, including 2 school principals, 2 teachers, 2 social workers, 4 younger tutors, and 4 older people, were invited to share their views about the characteristics for the local EA. Phase 1 results identified the characteristics of local EA, such as the cross-bureau, cross-sector, cross-profession, and cross-age collaborations, the seed money, and an independent management committee. Local EAs have the ability to enhance the value of a “giving culture” and the positive image of the older people. They also provided platforms to train volunteers and health promoters, as well as to develop the new other learning experiences curriculum. In addition, it was found that Confucianism has an important impact on running the local EA model. Together with older people’s feedback, the micro level of evaluation (Phase 2) was undertaken to evaluate the effect of the proposed teaching-learning style used in the EA model. In Phase 2, a multiple method, a quasi-experimental study and in-depth interviews were conducted with participants in the “lecture and practicum” group. The quasi-experimental study evaluated the proposed teaching-learning style employed in the Health Frontier Trainers’ Program on learning performance. A convenience sample was recruited over the course of a month. Up to 40 participants formed the “lecture and practicum” group, whereas 30 participants formed the “lecture-only” group. Pre- and post-tests on the learning performance were administrated before and after the programs were applied to both groups. Assessment scores after the programs were recorded, after which their mean scores were compared. In-depth interviews were also conducted. A total of 10 participants consisting of 6 older participants and 4 younger participants from the “lecture and practicum” group were invited for interviews. Data were collected to examine the perceptions of the participants regarding the program. A statistically significant difference between the two study groups was found only in the change in the learning performance of the older participants. The older participants in the “lecture and practicum” group experienced a greater enhancement in their learning performance than those in the “lecture-only” group, thus, the proposed teaching-learning style was confirmed to be more effective toward the learning of older people. The proposed teaching-learning style included experiential-based learning, which emphasized the experiential nature of learning and interaction in the context of reality. Moreover, several themes were identified from interview data, such as developing knowledge and skills, enhancing intergenerational learning, bridging theory and practice, and perceived difficulty in the learning topic. These themes indicated that older people preferred experiential learning to lifelong learning. In conclusion, the characteristics of the local EA model were identified. Experiential learning was found to be better than lecture-based learning. Based on these findings, the local EA could develop a preferred lifelong learning model for older people when the local EA model with local characteristics is combined with the element of experiential learning

Wave-packet treatment of neutrino oscillations and its implications on determining the neutrino mass hierarchy

We derive the neutrino flavor transition probabilities with the neutrino treated as a wave packet. The decoherence and dispersion effects from the wave-packet treatment show up as damping and phase-shifting of the plane-wave neutrino oscillation patterns. If the energy uncertainty in the initial neutrino wave packet is larger than around 0.01 of the neutrino energy, the decoherence and dispersion effects would degrade the sensitivity of reactor neutrino experiments to mass hierarchy measurement to lower than 3 $\sigma$ confidence level

Renal and Splenic Micro-Infarctions Following Bronchial Artery Embolization with Tris-Acryl Microspheres

A bronchial artery embolization (BAE) is an important therapeutic method used to control acute and chronic hemoptysis. We report a case of multiple micro-infarcts involving both the kidneys and spleen, following a BAE with 500-700 µm crossed-linked tris-acryl microspheres (Embospheres) in a patient with bronchial artery pulmonary vein shunts. The superior penetration characteristics of the microspheres may have resulted in the greater tendency to cross the bronchial artery pulmonary vein shunts, which subsequently caused the systemic infarcts in our patient. We propose the use of larger sized microspheres (700-900 µm), which may aid in avoiding this complication

Parenting approaches, family functionality, and internet addiction among Hong Kong adolescents

© 2016 Wu et al. Background: Internet addiction (IA) among adolescents has become a global health problem, and public awareness of it is increasing. Many IA risk factors relate to parents and the family environment. This study examined the relationship between IA and parenting approaches and family functionality. Methods: A cross-sectional study was conducted with 2021 secondary students to identify the prevalence of IA and to explore the association between adolescent IA and familial variables, including parents' marital status, family income, family conflict, family functionality, and parenting approaches. Results: The results revealed that 25.3 % of the adolescent respondents exhibited IA, and logistic regression positively predicted the IA of adolescents from divorced families, low-income families, families in which family conflict existed, and severely dysfunctional families. Interestingly, adolescents with restricted Internet use were almost 1.9 times more likely to have IA than those whose use was not restricted. Conclusions: Internet addiction is common among Chinese adolescents in Hong Kong, and family-based prevention strategies should be aligned with the risk factors of IA.Link_to_subscribed_fulltex

Dense Cranial Electroacupuncture Stimulation for Major Depressive Disorder—A Single-Blind, Randomized, Controlled Study

BACKGROUND: Previous studies suggest that electroacupuncture possesses therapeutic benefits for depressive disorders. The purpose of this study was to determine whether dense cranial electroacupuncture stimulation (DCEAS) could enhance the antidepressant efficacy in the early phase of selective serotonin reuptake inhibitor (SSRI) treatment of major depressive disorder (MDD). METHODS: In this single-blind, randomized, controlled study, patients with MDD were randomly assigned to 9-session DCEAS or noninvasive electroacupuncture (n-EA) control procedure in combination with fluoxetine (FLX) for 3 weeks. Clinical outcomes were measured using the 17-item Hamilton Depression Rating Scale (HAMD-17), Clinical Global Impression-severity (CGI-S), and Self-rating Depression Scale (SDS) as well as the response and remission rates. RESULTS: Seventy-three patients were randomly assigned to n-EA (n = 35) and DCEAS (n = 38), of whom 34 in n-EA and 36 in DCEAS group were analyzed. DCEAS-treated patients displayed a significantly greater reduction from baseline in HAMD-17 scores at Day 3 through Day 21 and in SDS scores at Day 3 and Day 21 compared to patients receiving n-EA. DCEAS intervention also produced a higher rate of clinically significant response compared to n-EA procedure (19.4% (7/36) vs. 8.8% (3/34)). The incidence of adverse events was similar in the two groups. CONCLUSIONS: DCEAS is a safe and effective intervention that augments the antidepressant efficacy. It can be considered as an additional therapy in the early phase of SSRI treatment of depressed patients. TRIAL REGISTRATION: Controlled-Trials.com ISRCTN88008690

Oral health of community dwelling elders in Hong Kong

Introduction: The world’s population is ageing and the elders are vulnerable to oral health problems. This project aimed to observe the oral health status of community dwelling elders in Hong Kong, investigate the oral health impact on their quality of life and nutritional status, and provide oral health education and preventive service. Methods: Community dwelling elders (65 or above) were recruited from five community centers. An interviewer-administered questionnaire was completed to collect information on their socio-demographic background and oral health perception/practice. Their oral health related quality of life (OHQoL) and nutritional status were measured by using the Geriatric Oral Health Assessment Index (GOHAI) and Mini-Nutritional Assessment (MNA), respectively. Their tooth and periodontal status, oral hygiene and soft tissues were examined. Individualized advice, oral health education and scaling were provided. Results: A total of 195 elders participated. Despite their sound knowledge on dental caries, their awareness of the causes and risk factors of periodontal diseases was low. Several misconceptions of oral health were common and their expectation towards oral health was low. Although 81% brush their teeth at least twice a day, over 75% did not perform interdental cleaning mainly due to unawareness of the necessity (32%) and lack of skills (42%). Their dental visits were treatment-driven and mainly for pain-relieving and emergency care. Only 19% were regular dental attendees. The mean (SD) DMFT was 8.9 (7.8). Over 60% had periodontal pockets; 6% were edentulous and 38% had fewer than 20 teeth. The mean (SD) total GOHAI score was 56.4 (8.0); 60% reported negative impact of oral health on their quality of life. The mean (SD) MNA score was 25.2 (2.9); 30% had malnutrition or were at risk. Multivariate analysis showed that tooth loss and untreated decayed teeth (DT) were significant determinants of poor OHQoL; older age, higher education level, and poorer OHQoL were significantly associated with higher risk of malnutrition (all p<0.05). Conclusions: Oral health problems are common among community dwelling elders in Hong Kong. Their oral health awareness and practice are yet to be improved. Tooth loss and unmet treatment need for dental caries significantly compromise elders’ quality of life, which in turn increases their risk for malnutrition. Outreach oral health education and service are well received by the community.published_or_final_versio

Evaluation of the ClearVoice Strategy in Adults Using HiResolution Fidelity 120 Sound Processing

ObjectivesThis study aimed to evaluate the benefits of ClearVoice strategy on speech perception in noise and in everyday listening situations in Cantonese-speaking cochlear implant users.MethodsTwelve experienced adult users of the Harmony implant and HiRes 120 sound processing participated in the study. The study employed a prospective within-subjects design wherein speech recognition in adults using HiRes 120 without ClearVoice turned on (control option) was compared to their performance with HiRes 120 with ClearVoice turned on. Each subject was evaluated with two different ClearVoice gain settings: -12 dB (ClearVoice medium) and -18 dB (ClearVoice high) after one-week of use. The Cantonese hearing in noise test and a questionnaire were used as the outcome measures.ResultsSubjects performed significantly better with ClearVoice medium than with control option in noise. No significant difference in performance was noted among the 3 settings in quiet. Most subjects reported high level of satisfaction with ClearVoice in daily listening situations and preferred to keep ClearVoice on.ConclusionClearVoice can help cochlear implant recipients to hear better in noise

Photo-reactive charge trapping memory based on lanthanide complex

Traditional utilization of photo-induced excitons is popularly but restricted in the fields of photovoltaic devices as well as photodetectors, and efforts on broadening its function have always been attempted. However, rare reports are available on organic field effect transistor (OFET) memory employing photo-induced charges. Here, we demonstrate an OFET memory containing a novel organic lanthanide complex Eu(tta)&lt;sub&gt;3&lt;/sub&gt; ppta (Eu(tta)&lt;sub&gt;3&lt;/sub&gt; = Europium(III) thenoyltrifluoroacetonate, ppta = 2-phenyl-4,6-bis(pyrazol-1-yl)-1,3,5-triazine), in which the photo-induced charges can be successfully trapped and detrapped. The luminescent complex emits intense red emission upon ultraviolet (UV) light excitation and serves as a trapping element of holes injected from the pentacene semiconductor layer. Memory window can be significantly enlarged by light-assisted programming and erasing procedures, during which the photo-induced excitons in the semiconductor layer are separated by voltage bias. The enhancement of memory window is attributed to the increasing number of photo-induced excitons by the UV light. The charges are stored in this luminescent complex for at least 10&lt;sup&gt;4&lt;/sup&gt;s after withdrawing voltage bias. The present study on photo-assisted novel memory may motivate the research on a new type of light tunable charge trapping photo-reactive memory devices
