Structural Effects Of Network Sampling Coverage I: Nodes Missing At Random, Jeffrey A. Smith, James Moody

Department of Sociology: Faculty Publications

Network measures assume a census of a well-bounded population. This level of coverage is rarely achieved in practice, however, and we have only limited information on the robustness of network measures to incomplete coverage. This paper examines the effect of node-level missingness on 4 classes of network measures: centrality, centralization, topology and homophily across a diverse sample of 12 empirical networks. We use a Monte Carlo simulation process to generate data with known levels of missingness and compare the resulting network scores to their known starting values. As with past studies (Borgatti et al., 2006; Kossinets, 2006), we find that …

Plant and Soil Sciences Faculty Publications

Social Differentiation And Age-Friendly Characteristics : A Case Study In Tuen Mun, Yuen Ling, Elaine Yau

Lingnan Theses

Hong Kong is one of Asia’s more demographically-aged cities, with 14% of population aged 65+ in 2012, projected to be 23% by 2025. Facilities and transport are generally good by world standards although the urban environment may not consistently be particularly ‘age-friendly’. Drawing on a range of urban sub-areas, this research investigated the ‘age-friendliness’ of Tuen Mun, a ‘new town’ of half a million population in Hong Kong. This study was also interested in socio-cultural variables and age-friendly cities (AFC) characteristics in its predominantly Chinese population, and relationships with psychological well-being (PWB).

A total of 503 participants aged 50 years …

如何提升長者的自我增值能力研究計劃, 香港婦女基金會何郭佩珍耆康中心, Asia-Pacific Institute Of Ageing Studies, Lingnan University 嶺南大學亞太老年學研究中心

APIAS Research Report 研究報告

香港婦女基金會何郭佩珍耆康中心致力推動長者老有所為，自我增值。此研究旨在了解中心會員參與班組及義工的情況，並思考如何增加其參與度。中心鼓勵會員從單向接收知識增值至學以致用，但事與願遺，暫時會員傾向只作為服務使用者參加班組，但很少作為服務提供者參與義務工作及自務義工活動。研究指出儘管會員都知道個人在社群的義務，包括伸手助人、弘揚傳統、貢獻社區，但他們都多在乎自身，如時間運用、身體狀況等，少有推己及人，未能從自助跨越到互助而達致增值。在眾多活動的選擇中，他們找不到充分的理由去選擇參與義工服務。研究認為中心在鼓勵服務使用者在接受服務後馬上成為義工的轉變過程中已遇到困難，應將服務使用者循序漸進引導成為服務組織者。研究亦發現中心會員普遍具有高中教育水平和心境年齡年輕的義工活動參與基礎，中心需加強為會員帶來價值觀的改變，讓會員明白義務工作可得到成就、尊重、認同。這些認知有助成為會員參與義工服務的動機，最終促使他們從服務使用者轉變成為服務提供者。

An Econometric Approach For Modeling Population Change In Arkansas, David Alexandro Ramirez

Open Access Theses & Dissertations

This study models population in the state of Arkansas using a small econometric model, and is similar to a previous demographic model developed by Fullerton and Barraza de Anda (2008). The components of population change consist of births, deaths, and net migration. Births minus deaths equal natural increase, and population in the current period is population from the previous period plus natural increase plus net migration. Births and deaths are modeled as functions of a one period autoregressive lag as well as national trends. Net migration is also modeled as a one period lag of itself in addition to relative …
