Effects of age-based stereotype threat on time-based prospective memory.

The present study aimed to investigate the effect of a blatant activation of age-based stereotype threats (ABST) on time-based prospective memory (TBPM) in older adults. A sample of 74 adults from Hong Kong was randomly assigned to one of the two experimental conditions: the stereotyped condition ( = 36) or the neutral condition ( = 38). Participants were asked to read fictitious news reports related to dementia (stereotyped condition) or the importance of English oral skills (neutral condition).

Broad-scale impacts of coastal mega-infrastructure project on obligatory inshore delphinids: A cautionary tale from Hong Kong.

Inshore marine habitats experience considerable anthropogenic pressure, as this is where many adverse effects of human activities concentrate. In the rapidly-changing seascape of the Anthropocene, Hong Kong waters at the heart of world's fastest developing coastal region can serve as a preview-window into coastal seas of the future, with ever-growing anthropogenic footprint. Here, we quantify how large-scale coastal infrastructure projects can affect obligatory inshore cetaceans, bringing about population-level consequences that may compromise their long-term demographic viability.

Find Joy in Sorrows: The Role of Hope in Buffering the Psychological Impact of COVID-19 on Chinese University Students in Hong Kong.

The global coronavirus disease 2019 (COVID-19) crisis has exerted significant psychological impacts on university students who have faced drastic changes in the learning mode and suspension of classes. Despite these challenges, many students maintained subjective well-being. In this study, we examined the role of "hope" as a potential protector to maintain their subjective well-being when facing adversity during this global crisis.

Positive Emotions, Hope, and Life Satisfaction in Chinese Older Adults: An Application of Broaden-and-Build Model.

According to the broaden-and-build theory, positive emotions can broaden our awareness and build psychological resources, which leads to better psychological outcomes. Previous studies demonstrated that hope partially mediates the association between positive emotions and life satisfaction in college students. Yet, there has no similar model been tested among older adults.

Associations among social participation types, mental and subjective well-being in Chinese older adults during the COVID-19 pandemic.

Aims: This study investigated the relationships between specific types of social participation and well-being variables (i.e., life satisfaction, positive affect, negative affect, symptoms of depression and anxiety) in Chinese older adults in Hong Kong.

The psychometric properties of the Lubben Social Network Scale (LSNS-6) and its associations with well-being indicators in Hong Kong older adults.

Objective: Social networks play a vital role in facilitating late-life health and well-being. The current research sought to examine the psychometric properties of the abbreviated Lubben Social Network Scale (LSNS-6) among community-dwelling Hong Kong Chinese older adults and to explore the association between social network and well-being indicators such as life satisfaction, functional social support, loneliness and anxiety.

Methods: We administered the LSNS-6 scale to 324 older adults (mean = 71.

Integration of hospital and community care for paediatric ophthalmology: A mixed-methods study.

Background: To explore collaborative care models for paediatric eye care that integrate hospital and community-based care to address access blocks.

Methods: Sequential referrals to a tertiary paediatric ophthalmology clinic between April and October 2019 and subsequent encounters up until July 2020 at a major metropolitan public children's hospital in Sydney, Australia, were reviewed to identify those cases suitable for community care. Semi-structured phone interviews were conducted with eye health service providers, including ophthalmologists, orthoptists and optometrists, as well as service users to explore their perspectives on potential changes to service delivery.

Photo-identification comparison of four Indo-Pacific humpback dolphin populations off southeast China.

Indo-Pacific humpback dolphins (Sousa chinensis) inhabit shallow coastal waters of the Indo-Pacific region including southeast China, with at least 6 putative populations identified to date in Chinese waters. However, the connectivity among these populations has not yet been fully investigated. In the present study, we compared and cross-matched photographic catalogs of individual dolphins collected to date in the Pearl River Delta region, Leizhou Bay, Sanniang Bay, and waters southwest of Hainan Island, a total of 3158 individuals, and found no re-sighting of individual dolphins among the 4 study areas.

The detrimental impacts of negative age stereotypes on the episodic memory of older adults: does social participation moderate the effects?

Background: Older adults' cognitive abilities can be impaired through priming of negative age stereotypes. However, it is unclear whether the effects of negative priming can be extended to episodic memory, which is believed to be the most age-sensitive type among the long-term memory systems, in Asian populations. Social participation has recently emerged as a potential protective factor for maintaining the cognitive function of older adults.

Epidermal Lesions and Injuries of Coastal Dolphins as Indicators of Ecological Health.

Humpback dolphins (genus Sousa), obligatory inshore delphinids, are frequently exposed to adverse effects of many human activities. In Hong Kong, one of the world's most urbanised coastal regions, ~ 50% of the dolphins suffer from at least one type of epidermal lesions, likely related to anthropogenically degraded habitat. Furthermore, one in every ten dolphins has physical injuries indicative of vessel collisions, propeller cuts and fishing-gear entanglements.

Indo-Pacific humpback dolphins (Sousa chinensis) in Hong Kong: Modelling demographic parameters with mark-recapture techniques.

Indo-Pacific humpback dolphins (Sousa chinensis) inhabiting Hong Kong waters are thought to be among the world's most anthropogenically impacted coastal delphinids. We have conducted a 5-year (2010-2014) photo-ID study and performed the first in this region comprehensive mark-recapture analysis applying a suite of open population models and robust design models. Cormack-Jolly-Seber (CJS) models suggested a significant transient effect and seasonal variation in apparent survival probabilities as result of a fluid movement beyond the study area.

Age-Friendliness and Life Satisfaction of Young-Old and Old-Old in Hong Kong.

Age-friendliness, promoted by the World Health Organization (WHO), aims to enable and support individuals in different aspects of life for fostering life satisfaction and personal well-being as they age. We identified specific aspect(s) of age-friendliness associated with life satisfaction and examined similarities and differences in age-friendliness and life satisfaction in young-old and old-old adults. Six hundred and eighty-two ageing adults were asked to complete a survey questionnaire consisting of the Age-friendly City Scale, Satisfaction with Life Scale, and sociodemographic variables.

Threshold of long-term survival of a coastal delphinid in anthropogenically degraded environment: Indo-Pacific humpback dolphins in Pearl River Delta.

Defining demographic and ecological threshold of population persistence can assist in informing conservation management. We undertook such analyses for the Indo-Pacific humpback dolphin (Sousa chinensis) in the Pearl River Delta (PRD) region, southeast China. We use adult survival estimates for assessments of population status and annual rate of change.

Humpback Dolphins in Hong Kong and the Pearl River Delta: Status, Threats and Conservation Challenges.

In coastal waters of the Pearl River Delta (PRD) region, the Indo-Pacific humpback dolphin (Sousa chinensis) is thought to number approximately 2500 individuals. Given these figures, the putative PRD population may appear strong enough to resist demographic stochasticity and environmental pressures. However, living in close proximity to the world's busiest seaport/airport and several densely populated urban centres with major coastal infrastructural developments comes with challenges to the long-term survival of these animals.

An integrated content and metadata based retrieval system for art.

A new approach to image retrieval is presented in the domain of museum and gallery image collections. Specialist algorithms, developed to address specific retrieval tasks, are combined with more conventional content and metadata retrieval approaches, and implemented within a distributed architecture to provide cross-collection searching and navigation in a seamless way. External systems can access the different collections using interoperability protocols and open standards, which were extended to accommodate content based as well as text based retrieval paradigms.
