第三人效果研究已經過三十餘年的發展，但比較第三人效果認知對於行為層面預測力的研究仍然相當有限。本研究以霧霾調查紀錄片《穹頂之下》為研究主題，從心理學利己、利他動機的視角出發，探討第三人效果認知層面與行為層面間的關係。本研究在上海、深圳兩地進行問卷調查，共訪問926名大學生，研究結果顯示，受訪者會傾向於認為環保資訊對他人產生的影響大於對其自身產生的影響；然而，本研究發現，「對自己影響的認知」比「對他人影響的認知」更能顯著預測受訪者的蒐集資訊與響應性行為。同時，本研究結果顯示，「議題與個人的關聯程度」、「對訊息的涉入程度」均會影響「對自己影響的認知」和「對他人影響的認知」對行為意願的預測力。這些研究發現對於豐富第三人效果的理論框架有一定貢獻，同時亦為環境保護資訊的傳播提供了一定的實踐啟示。 / The third-person effect (TPE) hypothesis has been developed for over 30 years. However, very limit amount of TPE research have focus on comparing the predictive power of "perceived influence on self" and "perceived influence on others". This research fills the research gap by examining the relation between perceptual and behavioral components in the context of a Chinese documentary concerning haze weather, Under the Dome. Using the data from a survey concerning public opinion towards the haze documentary involving a sample of 939 college students in Shanghai and Shenzhen, results indicate that respondents tend to perceive the haze documentary have a larger influence on others than on themselves regardless of their perceived desirability of the documentary, and the perceived influence on self is a better predictor of the behavioral component compared to the perceived influence on self. Furthermore, issue relevance and media message involvement both have an influence on the predictive power of perceived influence on self and perceived influence on others. The research findings can contribute to the theoretical framework of TPE, as well as provide empirical implication for pro-environment communication. / Detailed summary in vernacular field only. / 張晓. / Thesis (M.Phil.)

Thanks to globalization, which leads to an ever increasing growth in international trade and inevitably a vast emergence in shipping activities, environmental impact is receiving increasing attention around the world. Maritime industry is under great pressure to improve its performance towards greener practices. This study attempts to provide an insight to the feasible adoption of onshore power system (OPS) for ocean-going vessels (OGVs) in the container terminals in Hong Kong. Given that OGVs are the major contributors to pollutants like carbon dioxide (CO2), sulfur oxides (SOx), nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO) and various particulate matter (PM), it is of overriding importance to tackle and rectify the environmental impact of these pollutants, in particular in a densely populated port city like Hong Kong. As such, main focuses in this study laid in the environmental and financial benefits in adopting OPS technology in the container terminals in Hong Kong. Information of container vessel arrivals and engine emissions at Kwai Chung-Tsing Yi Container Terminals (KTCT) in 2011 are analyzed. By employing the energy-based approach, it is revealed that the use of OPS at KTCT could substantially reduce the CO2, SOx, NOx and PM10 levels within Hong Kong waters by 16%, 84%, 95% and 94% respectively. In addition, as far as financial benefits are concerned, this study adopted the life cycle cost analysis (LCCA), in which the capital investment cost, operational cost and maintenance cost of OPS are taken into account. Analytical data provide sound return on investment with a discounted payback period as low as 6.4 years, and up to 29% of annual energy cost saving when compared with traditional diesel powered OGVs as well. To further support the feasible implementation of OPS in Hong Kong, some real-life cases over the globe are gathered to contrast the successful adoption of OPS. Altogether with the recent compromised international standards for OPS and more stringent emission regulations enacted by International Maritime Organization (IMO), European Commission (EC) and California Air Resources Board (CARB), the commission of OPS in the container terminals in Hong Kong is just around the corner. This dissertation provides innovative management measures from an environmental perspective to promote the adoption of OPS at KTCT. Besides, incentive policy from the HKSAR Government should be expedited, stimulating the sustainable industrial practice in Hong Kong. / published_or_final_version / Environmental Management / Master / Master of Science in Environmental Management
