A Comparative Analysis Of Double Reduction Policy In China, Hai Yan Wang

SOC 605 Comparative Social Policy Research Project - Student Works

The "double reduction" policy in China is designed to reduce the workload of students and prohibit out-of-school training. However, the results are not as expected. This study aims to identify potential factors that could contribute to the success of China's "double reduction" policy. The data were analysed using a mix of quantitative and qualitative methods (questionnaires for students and semi-structured interviews with teachers and parents). In total, 156 valid questionnaires were collected, and 3 teachers and 3 parents were interviewed. In addition, Finland and South Korea's experiences have been used for comparison for better improvement. The results indicate that inconsistent …

A Comparison Of Public Housing Policies For The Elderly In Hong Kong And Singapore, Sijing Bai

SOC 605 Comparative Social Policy Research Project - Student Works

With the society’s development and progress, people are seeking a long and healthy life with improved life quality and a better living environment. Like many other economies worldwide, Singapore and Hong Kong are experiencing rapid population aging. The social welfare policy in Singapore is based on the individual and family as the foundation, the community as the middle-level organization, and the government taking a residual complementary role. In contrast, the elderly care model in Hong Kong can be divided into three types: aging in place, residential care, and aging out of Hong Kong. According to current statistics, Hong Kong has …

「回首．動情．傳承」長者生命故事計劃, 嶺南大學亞太老年學研究中心 Asia-Pacific Institute Of Ageing Studies, Lingnan University, Chak Kwan Chan, Lai Ieng Lau, Pui Yiu Ho, Kwong Lam Wu, Hiu Tung Chan, Ying Laam Tang, Shuk Ling Wong, Wai Ching Lai, Kam Yin Lai, Chun Wai Lo, Yiu Long Tai, Ka Chung Kwong, Hon Wun So

Manual & Guide 手冊及指引

嶺南大學亞太老年學研究中心獲華人永遠墳場管理委員會（「華永會」）資助為期一年的「回首．動情．傳承」長者生命故事計劃(「計劃」)。此計劃旨在讓青年人認識長者生命經驗，學習克服困難與挫折以提升抗逆力，建立正向人生觀。

近年，主流媒體經常批評年輕人的負面人生觀，例如：「躺平主義」、「享樂主義」、「犬儒心態」等，亦不時看到青年人輕生的新聞。我們曾在大學內處理過不少受情緒困擾及企圖自殺的個案，與學生深入交流後，發現他們面對着沉重的學業壓力、財政困難或複雜的家庭關係，內心充滿掙扎不安。

此計劃讓嶺大學生與長者導師進行深度的對談，透過了解長者走過的路、他們經歷過的挫折和教訓，給予年輕人生命的啟示。如果我們以旅遊比喻人生，長者就像環遊世界的資深背包客，即使大家遊覽不同的地點、觀賞過不同的風景，他們總能夠分享一些旅遊的心得，讓新手遊客走少一點冤枉路，或領悟到旅遊的樂趣和意義。長者亦可以藉由敍述人生片段回顧他們生命中的故事，學習接納過去，增加自我認同感。青年人創作生命教育書冊，將長者積極的人生觀傳給年輕一代，並藉此鼓勵其他長者豁達地度過餘年。

我們於2022年初招募嶺南大學學生接受「生命故事敍述」培訓，內容包括：本港的人口老化現象、敍述治療理論、與長者溝通的技巧及模擬實踐練習等，以裝備同學的知識和技巧。本中心再向屯門、元朗區的長者機構發邀請信，誠邀長者擔任生命導師接受訪問。

嶺大安排同學以兩人一組的小隊形式，於2022年6至7月期間前往長者中心、日間護理中心、嶺南大學或長者家中，與十二位長者進行深入訪談。訪談結束後，同學根據訪談的內容，為長者書寫他們獨特的生命故事。例如在人離鄉賤的異國環境下，努力打拼事業的Alfred；堅持不懈持續進修的淑芹和馮春林；即使沒機會求學，仍憑一雙巧手闖出一片天的譚惠；在文化大革命的漩渦中，憑着熱忱而改變命運的蘭英；還有為家人無私奉獻的鳳群、歐婆婆、雅芳及細女；離鄉別井勇闖異地的阿美和阿水；即使被家人賣去做「妹仔」，仍能以「阿Q精神」面對的諒餘。

為保障長者的私隱權益，本書內所有刊登之故事皆經過受訪者或社工審閱，部份受訪者選擇以化名的形式來分享自己的故事，我們亦移除了部份敏感的個人資料。

Social Capital And Educational Well-Being: A Systematic Review (2010-2022), Pui Yiu Ho

SOC 605 Comparative Social Policy Research Project - Student Works

Social capital is evidenced as beneficial to educational achievements and it’s believed as important for students. Recent research of social capital and education moves beyond illustrating the effects of social capital on education achievements to a more comprehensive interrelationship between social capital and different aspects in development of students. To delineate the association between social capital and education in different aspects, this paper aims to systematically review quantitative studies examining the association between social capital and educational well-being. Three questions are of concern here. Question 1: Is there association relationship between social capital and educational well-being? Question 2: …

Platform Work, Social Risks And Social Welfare : A Qualitative Study On Workers’ Experiences And Views In Hong Kong, Cham Kit Ming

Lingnan Theses (MPhil & PhD)

Drawing on the social risk thesis, this research studies the risk and welfare experiences of Hong Kong workers working on food delivery platforms and courier platforms. A total of 23 platform workers involved in food delivery work and courier work on the crowdsourcing gig work platform were invited to in-depth interviews, leading to the discovery of workers’ perceptions of the six platform work-related risks, welfare experiences, and work freedom. The researcher argues that platform workers’ experiences result from power asymmetry on the individual, organisational, and institutional levels. The algorithmic control by the platform firms and the dependence of workers on …

Married Working Women And Work-Family Interface In Urban Ghana : A Holistic Approach, Kwaku Abrefa Busia

Lingnan Theses (MPhil & PhD)

The intersection of work and family has gained traction across various disciplines in an attempt to study how work and family life affect individuals, families, organisations and societies. Nonetheless, most studies on work-family interface (WFI) remain dominated by theories, concepts and experiences rooted in white, middle class and homogenous individuals in Western societies. Owing to these concerns, there have been widespread calls for more cross-cultural studies that capture the plurality of work-family realities and conceptualisation, especially from the Global South. Emphasis has also been made on the need to expand workfamily research beyond the often-studied professional workers and their families …

Lingnan Theses (Doctoral degree)

The social consciousness of residents has been changing since China's reform and opening up. The grassroots governance of the society has also become more and more difficult. In the last decade, the Chinese government has been improving the level of social community governance, and since COVID-19 pandemic, the government has been strengthening democratic social governance. It has become very possible to cultivate social consciousness and democratic consciousness among the residents in the community. I conducted two rounds of questionnaires and three rounds of interviews in several communities in Shandong province.

‘Aging In Place’ Or ‘Stuck In Place’? The Aging In Place Experiences Of Older Adults In A Gentrifying Neighborhood In Hong Kong, Ho Wing Lau

Lingnan Theses (MPhil & PhD)

Urbanization and population aging are two of the most critical global trends in the 21st century. In particular, the aging experiences of older adults living in gentrified urban areas has raised the attention of scholars from various disciplines. Urban aging concerns how and why some older adults can thrive in urban life while others are struggling to adapt. Hong Kong is experiencing ‘double aging’ —an aging population and a large scale of aging buildings, which make it particularly challenging to strike a balance between urban renewal and preservation of the community for older adults to age in place. The challenges …

Socioeconomic Status, Health, And Health Behaviours Of School-Aged Adolescents : The Psychosocial Mechanisms Of Social Capital, Evelyn Aboagye Addae

Lingnan Theses (MPhil & PhD)

Psychosocial social capital is advocated as a protective health asset and a non-monetary safety net that protect adolescents’ developmental outcomes against effects of socioeconomic inequalities. This study utilised advanced mixed research methods, and socioecological and health asset approaches to offer evidence on social capital’s psychosocial mechanisms and pathways through which socioeconomic status (SES) affects adolescents’ health and health behaviours. This is to offer appropriate policy and practice proposals in Ghana. The quantitative and qualitative studies respectively employed a multi-stage stratified cross-sectional survey data of 2,068 and 54 in-school Ghanaian adolescents (13-18yrs) in focus group discussions. Various univariate and bivariate (cross-tabulation-Chi …

Successful Aging Through Aging In Place : The Perspectives Of The Elderly And Adult Children In Shenzhen, Feng Huang

Dilemmas, Reactivity And Paper Support : The Support Conceptualisations And Experiences Of Students With Disabilities In Ghanaian Higher Education, Sarah Tara Sam

Lingnan Theses (MPhil & PhD)

Support is considered crucial for all higher education (HE) students including students with disabilities (SWDs). Disability support in higher educational institutions (HEIs) bridges resulting gaps from disabling barriers between the achievement of SWDs and their peers, while benefiting all students. Hence, the call for mainstreaming support for SWDs in HE. The drive towards widening access and participation in the Ghanaian educational system is evidenced in current educational policies including the Inclusive Education (IE) policy. However, scant literature exists on SWDs’ conceptualisations and experiences of support stemming from inclusive HE and its related policy in Ghana.

This study aimed at hearing …

江門市居家養老研究報告 = A Research Report On Ageing In Place In Jiangmen City, 嶺南大學-五邑大學居家養老聯合研究創新中心

APIAS Research Report 研究報告

本研究旨在瞭解江門市”社區居家養老”的狀況及需求，以便當局制定服務，讓長者能在自己最熟悉的地方養老。

硏究採用「量性研究」(Quantitative research method) 的方法，以問卷收集了482位居住在江門市城市、鄉鎮和農村60歲或以上長者的個人狀況和對居家養老的意見。

硏究發現8成以上長者偏好在家養老及覺得其現在居所環境適合養老，但超過一半長者居所的安全性成疑，這包括居所存在鼠患蟲患、住屋光線不足和缺乏維修等。另外，有大約3成認爲社區設施便利性有待提升。

在社交支持方面，超過8成老年人擁有良好的社交支持網絡，出入醫療場所和在生活上遇到難題時能獲得幫忙；少部分無法尋求任何幫助。值得注意的是，尋求正式機構協助的長者不多。

在財務狀況方面，約6成長者主要收入來源為退休金，另外少於半數老年人依靠兒女資助。有部分受訪者依賴存款，政府補貼和勞動收入。受訪者月收入偏低，以1000~4000元爲主，部分沒有任何收人。被訪者的醫療保險覆蓋率接近9成，約有2成人對承擔醫療費用感到吃力。

參與是次研究的受訪者普遍身體狀況和自理能力良好，7成以上滿意當前生活狀態 (包括居所狀況、社會支持、居家安老安排、社區設施及其生活條件)，認爲目前條件能支持他們居家養老。

本研究提出五大建議。第一，雖然目前大部分受訪者滿意當前生活狀態，居家養老服務供給水平仍有改進空間。為應付老年人口急增，政府應加速發展養老業。第二，社區和居家環境需配合長者的身體機能和需要，進行適老化改造，以支持他們在家養老。第三，爲減輕長者醫療費用的負擔，建議政府篩查符合救助標準的長者，提高老年人醫療補貼。第四，為了讓更多老年人能在社區組織中獲得適切的正式服務支持，政府應加大服務購買力度，增加服務名額同時提升服務質素。第五，子女對年長父母的陪伴和依靠是不能缺乏的，但部分子女沒有很好地履行贍養義務。爲增加子女對年老父母的照顧力度，政府應從教育、媒體方面營造社會尊老敬老氛圍。

Hong Kong Youngsters Pursuing Career In The Greater Bay Area : Opportunities And Challenges, King Leung Cheng

SOC 605 Comparative Social Policy Research Project - Student Works

In the past two years, Hong Kong has undergone tremendous changes in its internal and external environments. Under the influence of social movements, Sino-US trade negotiations, pandemic and the global economic downturn, Hong Kong's local economy continues to be sluggish. The number of unemployed continues to rise, and the youth unemployment rate is much higher than that of other age groups. To get out of adversity, the younger generation needs diversified development, and the construction of the Guangdong-Hong Kong-Macao Greater Bay Area might just open up a new path for them.

Based on existing evidence, this study discusses Hong Kong …

Austerity And Suicide : Evaluating The Claims And Evidence, Liam John Beale

SOC 605 Comparative Social Policy Research Project - Student Works

Since the hit of the economic recession, many sociologists and media outlets have speculated upon the relationship between suicide and austerity and in many cases make unnuanced claims to direct causality. This paper discusses the claims of two pertinent research papers on the topic of ‘Austerity Suicides’, and ultimately attempts to provide a multi-factorial model that illustrates the extent to which extent government response to economic downturn may impact rates of individual suicides whilst also acknowledging phenomenological and cultural influences.

Understanding How Democracy Shapes Well-Being Of Countries In Europe And Asia, Wing Laam Ng

SOC 605 Comparative Social Policy Research Project - Student Works

There is no lack of literature talking about the relationship between well-being and democracy. However, little research has been done by separating the area. This study is going to explore the association between democracy and well-being again by separating the countries in Europe and Asia. Well-being is measured by life satisfaction, positive affect, negative affect and satisfaction towards the government while democracy refers to the Democracy Index by the Economist Intelligence Unit. In total, thirty one European countries and seventeen Asian countries are selected based on the availability of data and exclusion of Asia-Europe border countries. Pearson correlation coefficient and …

Pandora’S Box To Sex Offenders Or Gift To The Public? Reviewing Sex Conviction Record Check In Hong Kong, England And Wales, Tsz Yan Elizabeth Yau

SOC 605 Comparative Social Policy Research Project - Student Works

Qualitative research and literature review were conducted by interviewing two ex-sex offenders and a police officer in England for reviewing Sexual conviction record check(system) in Hong Kong, England and Wales. The major findings in the research showed the system might bring stress and labelling effect toward the ex-offenders. Many sex offenders might lack information about the system before discharge which might hinder their rehabilitation and reintegration to the society. Moreover, the protection of the system in Hong Kong could not cover some potential situations which might do harm to the victims. Five policy suggestions are made at the end of …

Comparison Of Ageing Policy Between Hong Kong And Singapore, Ka Wai Tam

SOC 605 Comparative Social Policy Research Project - Student Works

This research study aims to explore and compare the ageing policy between Hong Kong and Singapore. Population ageing itself is a dynamic process. The ageing of the population is caused by three reasons: the decline in the level of fertility, the decline in the death rate and the continuous extension of the average life expectancy of the population. It is an inevitable demographic phenomenon. However, under the globalization effect, although the world is getting more connected in the last few decades, all developed and developing countries are facing the same problem which is the ageing population. There are a lot …

“We Are Parents” : Changing Constructions Of Fatherhood And Fathering In Urban Zambia, Aurick Mubita

Lingnan Theses (MPhil & PhD)

There is ample evidence that the conceptualization of fatherhood and the involvement of fathers in families is changing in many societies. However, in sub-Saharan African countries, dedicated studies on fatherhood are still very limited and in Zambia, a review of literature showed that they are non-existent. To address this gap, this study used the framework of masculine compromise to explore the ways in which fatherhood is conceptualized, practiced, and negotiated in view of existing masculinity and fatherhood discourses. The study also examined how fathers dealt with existing discrepancies between their everyday fathering practices and cultural expectations. It also considered conditions …

香港鄉村地區長者居家養老的需要：錦田例案報告 = The Needs Of Ageing In Place In Rural Hong Kong: The Case Of Kam Tin, Chak Kwan, Dickon Chan, Mun Yu, Vera Tang, Chak Lung Lam, Wing Yin Li, Mei Ling Lee, Seung Wan Wong

APIAS Research Report 研究報告

香港面臨人口高齡化，政府統計處（2020）估計65 歲或以上人口會由2019年的120萬增加至2039年252 萬。長者佔總人口比例亦由18.4%上升至33.3%；而老年撫養比率（65 歲及以上人口相對每千名15 至64 歲人口的比率）將由249大幅上升至508。這意味着社會在撫養和照顧長者, 將會面對更大的壓力。另外，老年家庭人口亦不斷增加, 家庭所有成員均為長者的數目從2006年大約18萬上升至2016年超過30萬（增長67.4%）；獨居長者佔長者人口的比例亦由11.6%上升至13.1% （政府統計處，2018）。面對人口老化﹑雙老及獨居家庭等問題，社區需要有更全面的支持配套，才能使長者有良好的生活質素。

香港「社區照顧」（community care）政策源於政府於1977年發佈的《老人服務綠皮書》，強調居家安老為服務原則。該綠皮書（政府社會事務科，1977，頁5）指出，在社會及財政上而言，最可行的辦法就是提供適當的社會服務以幫助老年人能繼續與社會接觸在一起…當一個家庭在照顧老年人方面感到吃力時，政府便提供各種服務作爲對家庭一種的支持和協助。使老年人能繼續在家庭生活。

儘管政府一直強調「居家安老為本，院舍照顧為後援」，但多年來的資源分佈仍是以院舍照顧服務佔較大比例 （香港政策研究所，2017；羅致光，2018）。政府近年開始作出規劃上的調整，安老事務委員會（2017）於2017年發佈《安老服務計劃方案》建議加大社區照顧服務的比例，將社區照顧服務及院舍照顧服務的名額比率 由2016 年的1:1.3 加大至2031年的1:1.1（安老事務委員會，2017；羅致光， 2018）。因此, 加強「居家安老」政策，將會是政府其中一個安老服務規劃方向。

雖然政府及不同的社福機構在「居家安老」方面都有提供長者服務，但服務主要仍集中在城市，居住鄉村的長者因缺乏資源和渠道，較難得到協助。以居於元朗錦田 的長者為例，公營長者日間護理服務單位，全部位於元朗、天水圍或朗屏市區（社會福利署，2021），與他們的住處有一段距離。此外，針對鄉郊長者情況的「居家安老」服務規劃，亦未有在《安老服務計劃方案》中提及。因此, 本研究選取錦田區的長者作為主要訪談對象, 以了解鄉郊長者的「居家安老」情況。

錦田有悠久歷史，為最早來港定居的鄧氏族人居住地，有相當豐富的歷史建築群（陳天權，2016）。錦田面積龐大，近年開始規劃的錦田南和錦田北，佔地約1,400 公頃 （政府新聞公報，2014），佔元朗區14,430 公頃約一成面積，但人口只有 13,489，佔元朗人口約2% （政府統計處，2017；民政事務署，2021）。政府在錦 田規劃大綱中，仍保留不少地帶作「農業」、「自然保育區」或「鄉村式發展」用途（政府新聞公報，2014，2018）。因此，錦田仍然是本港主要的鄉郊地區之一。

本研究希望了解錦田長者的居家養老狀況和需求，為發展鄉郊長者服務的提供參考 資料。研究團隊探討長者於三個範疇的狀況，包括「社交支持」、「居所及社區支援 服務」和「長期護理服務的認識及意見」，並針對這三部分的發現提供相關建議。

The Influences Of Academic Discipline On Work-Based Learning : The Case Of Hong Kong, Yeuk Nam Ng

Lingnan Theses (MPhil & PhD)

Commonly known as student internship, work-based learning stands at the intersection of work and education, and possesses distinctive features worthy of sociological analysis. Previous studies on work-based learning have focused on the tension and conflicts between student interns, the university and the host organisation. A common problem is to treat student interns as a homogenous group, without taking into account their academic backgrounds when scrutinizing the experiences and outcomes of work-based learning. This research aims to overcome this problem by drawing upon the studies of “horizontal stratification” in the sociology of education, which set out to explain the differences in …
