General Life Satisfaction

LANGUAGE NOTE | Document text in English; abstract also in Chinese. In recent years, there is a growing interest amongst researchers regarding athletes’ retirement. While research in this area in western countries is slowly building, research in Hong Kong athletes has gained little attention. The present study examined Hong Kong elite athletes’ reasons for retirement and the influence of the retirement reasons on their perception of general life satisfaction and adjustment quality which reflected how well they adapted to their post-retirement life. Analysis of self-administered questionnaires from 75 retired athletes suggested that important reasons for their retirement were difficulties in coordinating sport and study or working demands, and physiological (e.g., injury, age) and financial reasons. Most of them perceived the transition out of sport as a smooth experience. Financial, physiological and burnout (tired of the lifestyle) reasons for retirement were found to be significantly negatively associated with athletes’ general life satisfaction. The more they retired due to the three kinds of reasons, the less satisfied they felt toward their current life. 近年來對於運動員退役的研究越來越多，特別是在西方國家，但是對於香港運動員退役的研究相對較少。本研究調查了香港精英運動員退役的原因及這些原因對他們適應退役後生活的狀況及總體生活滿意度的影響。根據75份問卷分析發現大多數香港精英運動員退役是由於難以協調運動訓練與工作或學習的時間，以及生理和經濟的原因。較多受訪者認為退役轉型的過程較為順利。研究還發現，出於經濟原因、生理原因(例如：傷病、年齡)、和厭倦運動訓練生活而退役，對於運動員退役後總體生活滿意度，有顯著的影響。而出於這三種原因而退役的運動員，對自己的總體生活滿意度則較低。

Abstract The swine industry has been constantly evolving to select animals with improved performance traits and to minimize variation in body weight (BW) in order to meet packer specifications. Therefore, understanding variation presents an opportunity for producers to find strategies that could help reduce, manage, or deal with variation of pigs in a barn. A systematic review and meta-analysis was conducted by collecting data from multiple studies and available data sets in order to develop prediction equations for coefficient of variation (CV) and standard deviation (SD) as a function of BW. Information regarding BW variation from 16 papers was recorded to provide approximately 204 data points. Together, these data included 117,268 individually weighed pigs with a sample size that ranged from 104 to 4,108 pigs. A random-effects model with study used as a random effect was developed. Observations were weighted using sample size as an estimate for precision on the analysis, where larger data sets accounted for increased accuracy in the model. Regression equations were developed using the nlme package of R to determine the relationship between BW and its variation. Polynomial regression analysis was conducted separately for each variation measurement. When CV was reported in the data set, SD was calculated and vice versa. The resulting prediction equations were: CV (%) = 20.04 – 0.135 × (BW) + 0.00043 × (BW)2, R2=0.79; SD = 0.41 + 0.150 × (BW) - 0.00041 × (BW)2, R2 = 0.95. These equations suggest that there is evidence for a decreasing quadratic relationship between mean CV of a population and BW of pigs whereby the rate of decrease is smaller as mean pig BW increases from birth to market. Conversely, the rate of increase of SD of a population of pigs is smaller as mean pig BW increases from birth to market.

ObjectivesTo assess the prevalence of potentially inappropriate medication (PIM) use in Hong Kong older patients visiting general outpatient clinics (GOPCs) between 2006 and 2014 and to identify factors associated with PIM use among older adults visiting GOPCs in 2014.DesignCross-sectional study.SettingGOPC.ParticipantsTwo study samples were constructed including a total of 844 910 patients aged 65 and above from 2006 to 2014 and a cohort of 489 301 older patients in 2014.MeasurementsTwo subsets of the 2015 American Geriatrics Society Beers criteria—PIMs independent of diagnosis and PIMs due to drug–disease interactions—were used to estimate the prevalence of PIM use over 12 months. PIMs that were not included in the Hospital Authority drug formulary or with any specific restriction or exception in terms of indication, dose or therapy duration were excluded. Characteristics of PIM users and non-PIM users visiting GOPCs in 2014 were compared. Independent associations between patient variables and PIM use were assessed by stepwise multivariable logistic regression analysis.ResultsThe 12-month period prevalence of PIM use decreased from 55.56% (95% CI 55.39% to 55.72%) in 2006 to 47.51% (95% CI 47.37% to 47.65%) in 2014. In the multivariable regression analysis, the strongest factor associated with PIM use was the number of different drugs prescribed (adjusted OR, AOR 23.01, 95% CI 22.36 to 23.67). Being female (AOR 0.89, 95% CI 0.85 to 0.87 for males vs females) and having a greater number of GOPC visits (AOR 1.83, 95% CI 1.78 to 1.88) as well as more than six diagnoses (AOR 1.43, 95% CI 1.36 to 1.52) were associated with PIM use.ConclusionsThe overall prevalence of PIM use in older adults visiting GOPCs decreased from 2006 to 2014 in Hong Kong although the prevalence of PIM use was still high in 2014. Patients with female gender, a larger number of medications prescribed, more frequent visits to GOPCs, and more than six diagnoses were at higher risk for PIM use.

This paper builds a house prices forecasting model for private residential houses in HongKong, based on general macroeconomic indicators, housing related data and demographicfactors for the period of 1980 to 2001. A reduce form economic model has been derivedfrom a multiple regression analysis where three sets and eight models were derived foranalysis and comparison. It is found that household income, land supply, population andmovements in the Hang Seng Index play an important role in explaining house pricemovements in Hong Kong. In addition, political events, as identified, cannot be ignored.However, the results of the models are unstable. It is suggested that the OLS may nota best method for house prices model in Hong Kong situation. Alternative methods aresuggested.

River revitalization, also called river restoration, has been implemented globally to restore urban river ecosystems that would benefit both the environment and local residents in various ways. The Hong Kong government has been attempting to revitalize local urban rivers; however, the perception and value of river restoration have not been assessed. With the application of a contingent valuation method, a questionnaire survey was designed to capture the attitude, place attachment, and willingness to pay (WTP) of Hong Kong residents in the context of urban rivers and river revitalization, and a proposed scenario for revitalization is given. The relationships among WTP, attitude and place attachment were explored through regression analysis. A total of 400 questionnaire samples were collected from Hong Kong residents, and over 75% of respondents were willing to pay for the proposed scenario. The results from regression analysis indicated that attitude, place dependence, place identity, and place social bonding positively influenced WTP and WTP bid amounts. In contrast, the place effect was unexpectedly found to be negatively correlated with WTP. Implications were drawn from these results, and recommendations were made concerning the features to be restored and conserved in future river revitalization work and the need to provide quality urban nature-based spaces for citizens.

The Impact

This study aims to examine the impact of specific dimensions of tourism impacts on Hong Kong residents’ satisfaction with the quality of life. While factor analysis is used to explore the attributes and dimensions of tourism impacts, multiple regression analysis is employed to determine the tourism impacts on residents’ satisfaction with the quality of life. It is evident from the results that two of the five dimensions of tourism impacts have positive influence on residents’ satisfaction. Image and infrastructure are found to be the important determinant factors in explaining the satisfaction. The impacts of environment, economy, and services in affecting satisfaction seem to be insignificant. In order to maintain tourism sustainability in Hong Kong, the local residents’ perception should be taken into consideration. Recommendations are provided to achieve mutual benefits and harmonious development.
