Humorous Field - Field to Humour = 幽默地誌 - 地致幽默

This is an experiment in spatial humour, and this assumption of humour can be applied to any urban space. Since this project starts with Lingnan University’s support of its Artist-in-Residence Program, it would seem appropriate to base the experiment around the university campus. Two straight lines were laid on the map of Tuen Mun. The lines extend to East-West through the ridge. The line to the South stretches across the valley and ends on the South coast. Two transects span a wide variety spaces and urban life in Tuen Mun. They would become the premises of this experiment. Exploring the two fixed paths, the artist observes and discovers potential humour along the route. This methodology was adapted from census data collection of marine life, in which marine biologists follow a selected transect across the sea floor and record the species of plants and sea animal encountered. 這是一個關於「空間幽默」的實驗，場所可以是任意的城市空間。 感謝嶺南大學給予藝術家駐校的機會。此實驗以大學為中心，在地圖上劃出縱橫線。縱線由北面泥圍起，途經大學、新墟街市、屯門河、蝴蝶邨等，伸延至南面海岸終。橫線由東面山脊始，途經虎地、兆康西鐵站、小坑村等，到西面山脊止。兩條直線貫穿之地大致包含了屯門社區各種空間及社群。藝術家遊走於這兩條指定路線，並嘗試運用自己的觀察及想像，發掘社區中的空間幽默。（此實驗方式效法海洋生態普查實驗：在海底拉出一條五十米長直绿，觀察和記錄所經之處的魚類品種及大小）。https://commons.ln.edu.hk/vs_artist_catalog/1019/thumbnail.jp

Why Do Countries Matter so Much in Corporate Social Performance?

Why do levels of corporate social performance (CSP) differ so much across countries? We answer this question in an examination of CSP ratings of more than 2,600 companies from 36 countries. We find that firm characteristics explain very little of the variations in CSP ratings. In contrast, variations in country factors such as stages of economic development, culture, and institutions account for a significant proportion of variations in CSP ratings across countries. In particular, we find that CSP ratings are high in countries with high income-per-capita, strong civil liberties and political rights, and cultures oriented toward harmony and autonomy. Furthermore, we find that home country factors explain a smaller portion of the overall variations in CSP for multinationals and cross-listed firms than for non-multinationals and pure domestic firms, respectively

C1-C8 volatile organic compounds in the atmosphere of Hong Kong: Overview of atmospheric processing and source apportionment

We present measurements of C1-C8 volatile organic compounds (VOCs) at four sites ranging from urban to rural areas in Hong Kong from September 2002 to August 2003. A total of 248 ambient VOC samples were collected. As expected, the urban and sub-urban sites generally gave relatively high VOC levels. In contrast, the average VOC levels were the lowest in the rural area. In general, higher mixing ratios were observed during winter/spring and lower levels during summer/fall because of seasonal variations of meteorological conditions. A variation of the air mass composition from urban to rural sites was observed. High ratios of ethyne/CO (5.6 pptv/ppbv) and propane/ethane (0.50 pptv/pptv) at the rural site suggested that the air masses over the territory were relatively fresh as compared to other remote regions. The principal component analysis (PCA) with absolute principal component scores (APCS) technique was applied to the VOC data in order to identify and quantify pollution sources at different sites. These results indicated that vehicular emissions made a significant contribution to ambient non-methane VOCs (NMVOCs) levels in urban areas (65±36%) and in sub-urban areas (50±28% and 53±41%). Other sources such as petrol evaporation, industrial emissions and solvent usage also played important roles in the VOC emissions. At the rural site, almost half of the measured total NMVOCs were due to combustion sources (vehicular and/or biomass/biofuel burning). Petrol evaporation, solvent usage, industrial and biogenic emissions also contributed to the atmospheric NMVOCs. The source apportionment results revealed a strong impact of anthropogenic VOCs to the atmosphere of Hong Kong in both urban/sub-urban and rural areas. © 2006 Elsevier Ltd. All rights reserved

Interview by Kwok Ming Fung

Mr. Sung in interviewed with me at 3/F conference room, General Education Building, Lingnan College on 19th April. He talks with a great deal of feeling about his childhood. It sounds interesting. He has 7 brothers and lives with his parent and his grandmother during his childhood. His father is work in business field and his mother is housewife and his grandmother is very traditional women. Thus his family is not poor. His mother and his elder brothers do not care the finical support of his family so that Mr. Sung and his brothers no need to work outside when they were small can only focus on their studying. When he was studing primary school, he had been changed from original scholl to a new one because his academic result is not good. It is quite difficult for him to adopt the new environment. Forunately, he familars with his classmate no longer via playing basketball and feeding little animal such as rabbit. After promoting secondary school, he felt that there are quite great pressure came from assessment and serious teacher. On the other hand, the good academic result of his elder brother is one of the major sources of pressure. He gradually looks after and concern about his smaller brothers when he was growing

Chronic swallowing ability in nasopharyngeal cancer survivors after radiotherapy with or without chemotherapy

In light of the lack of multidimensional data of long-term swallowing functions in nasopharyngeal cancer (NPC) survivors, the current study investigated NPC survivors’ long-term swallowing dysfunctions after radiotherapy or chemoradiation by a multidimensional protocol and explored their relationships with demographic and treatment-related variables. Twenty-seven participants were recruited and assessed through oromotor assessment, fiberoptic endoscopic evaluation of swallowing and quality-of-life questionnaires. Nearly half of the participants had oromotor deficits (47.6%) and penetration in at least one of the swallowing trials (45.8%). All participants had pharyngeal residue in valleculae and most participants have residue in pyriform sinuses (81.8%) in at least one of the swallowing trials. Limitations in the activity and participation domains were prevalent though large variation in functioning was noted. Comparison between groups indicated that participants treated with concurrent chemotherapy have significantly less degree of penetration or aspiration and less residue in valleculae on oral trials for extra thick liquid than those treated with radiotherapy alone. Correlation analysis indicated that degree of penetration in thin liquid, mildly thick liquid and amount of residue residing on valleculae in extra thick liquid increase with the number of years since completion of radiotherapy. Functioning in the activity and participation domains also decreased with time since completion of radiotherapy. Regression analysis indicated that number of years since completion of radiotherapy was a significant predictor for pharyngeal residue. The deteriorating trend identified provided evidence to the need of continuous monitoring in swallowing functions in nasopharyngeal cancer survivors. Further research to identify risk factors for long-term swallowing problems and ways to minimize long-term swallowing problems are neededfor early identification and maximising swallowing functions for nasopharyngeal cancer survivors.published_or_final_versionSpeech and Hearing SciencesBachelorBachelor of Science in Speech and Hearing Science

Zero-configuration identity-based IP network encryptor

For corporations or individuals who wish to protect the confidentiality of their data across computer networks, network-layer encryption offers an efficient and proven method for preserving data privacy. Network layer encryption such as IPSec is more flexible than higher layer solutions since it is not application-dependent and can protect all end-to-end traffics that go between two hosts. Using IPSec, two hosts must first establish a session key through message exchanges before they can communicate. In this paper, we present an Identity Based Encryption (IBE) scheme that allows a host to calculate the per-packet encryption key based on the IP address of the destination host, without going through the expensive key exchange process as in IPSec. Our mechanism is compatible with the current IP protocol and we tested our scheme with live HTTP and ICMP traffic. Our results show that our protocol provides a zero-configuration network layer encryption solution for end-to-end secure communications that is ideal for consumer electronics applications. © 2006 IEEE.published_or_final_versio
