This talk first goes over the meanings of ethnic and cultural identity, and then explores ethnic and cultural identity in Hong Kong. Can a South Asian who has grown up in Hong Kong be a Hongkonger?  Can an African asylum seeker be a Hongkonger?  Can a mainland Chinese graduate student at CUHK be a Hongkonger?   Can I be a Hongkonger?  What is a Hongkonger?  On the basis of extensive discussion among all present at the talk, we then analyze how ethnic and cultural identity are increasingly not given but chosen, as choices from a global cultural supermarket.  What, then, does this mean for the future of Hong Kong as a global/Chinese metropolis?

Scientifically, it is still debatable as to whether Africa is the origin of humanity. Although there are many documents that allude to this notion, others have assumed otherwise. Whether this is a myth or reality, that fact that Africa has seen its share of exodus from the continent cannot be disputed. In recent times, the migration out of Africa has assumed a new dimension. This trend is posing challenges to a continent full of resources and to destinations with historical connection either as colonialists or trade partners. In current times, Africa has also acquired new partners like China and India with aid and trade as items of discussion in addition to its traditional partners in this new scramble for Africa. What is the situation like on the African continent? What has it got to contribute to the global commons? In fact, who are the Africans? What are the challenges and prospects for prosperity? Seen as the last frontier of development, this presentation will seek to discuss the myths, identify the realities and highlight the challenges that confront the African continent. In conclusion, the prospects and potentials of Africa as an emerging destination of note, will be discussed.

A Plastic Ocean 的導演兼記者克雷格利森（Craig Leeson）透過拍攝藍鯨的故事，逐步將塑料海洋的真面目呈現眼前。拍攝團隊與多名科學家和研究員前往包括香港在內的世界各地，探索塑料污染的駭人事實，並揭露全球「用完即棄」的生活方式所帶來的嚴重後果。一隻隻飽著肚餓死的動物，一個個在垃圾山裡掙扎求存的島國居民，塑料海洋所揭示的不只是環境污染和生態破壞的問題，亦帶來道德價值和人文關懷的反思。作為同住地球的家人，作為21世紀的全球公民，我們應如何面對塑料污染所帶來的種種挑戰？

悲劇之於俗世，一般人是避之則吉。焉知於古代西方，希臘人對悲劇卻甘之如飴。就有關議題，尼釆論悲劇的「誕生」之論點固膾炙人口，但尼采此外其實還言及希臘悲劇的「死亡」，甚至其「再生」！其所指者何？我們對尼釆這一說法應如何解讀？要回答這些問題，我們或可循既充滿矛盾，但又最能概括人生的「哀樂」二字稍予探求。
