Introduction

Chapter 1 is an introduction to the book and provides an overview of the areas in which temporary structures are used, namely the construction and repair of buildings and bridges. A description of the different types of temporary structures is given together with an overview of the problems which may arise in temporary structures projects. The differences between temporary structures projects and projects for permanent structures are highlighted. An introduction to the particularities of the design, assembly, maintenance and operation of temporary structures is presented in this chapter. It is also emphasised that the book compares the design codes used in the USA, Europe, Australia and Hong Kong. Finally, the chapter concludes with an overview of the remaining chapters of the book.

The philosophies behind design codes with particular reference to the use of modern limit state design are presented in this chapter. Comments are made on the design life of temporary structures which vary considerably between different countries. Design codes of the USA, Europe and Australia/New Zealand for temporary structures are compared with particular reference to the loads combinations and the partial factors applied. It is noted that whilst the European design codes do not specify how construction, use and disassembly of the temporary structures are to be executed the USA code for scaffolding includes such specification. The Hong Kong code for bamboo scaffolds is described showing the similarities and differences between bamboo and metal scaffolds. The chapter concludes with design examples for selected temporary structures based on design codes.

Chapter 1 introduces the background of the Umbrella Movement, a protest movement that took hold in Hong Kong in 2014, and outlines the theoretical principles underlying the analysis of the role of media and communication in the occupation campaign. It explicates how the Umbrella Movement is similar to but also different from the ideal-typical networked social movement and crowd-enabled connective action. It explains why the Umbrella Movement should be seen as a case in which the logic of connective action intervenes into a planned collective action. It also introduces the notion of conditioned contingencies and the conceptualization of an integrated media system.

Chapter 1 introduces the main arguments of the book; outlines the approach, method, and data; defines key terms; and provides a chapter outline. Global theories of democratization have systematically excluded small states, which make up roughly 20 per cent of countries. These cases debunk mainstream theories of why democratization succeeds or fails. This book brings small states into the comparative politics fold for the first time. It is organized thematically, with each chapter tackling one of the main theories from the democratization literature. Different types of data are examined—case studies and other documentary evidence, interviews and observation. Following an abductive approach, in addition to examining the veracity of existing theory, each chapter is also used to build an explanation of how democracy is practiced in small states. Specifically, we highlight how small state politics is shaped by personalization and informal politics, rather than formal institutional design.

This study aims to examine the use of non-nutritive (NNSs) and low-calorie sweeteners (LCSs) in pre-packaged foods in Hong Kong and the differences in the number of NNSs/LCSs used between products from different regions. In a cross-sectional audit, the types of NNSs/LCSs used in 19,915 pre-packaged foods in Hong Kong were examined by searching the ingredients list of the included products for keywords related to 20 common NNSs/LCSs and their respective E-numbers. Prevalence of use of NNSs and LCSs, the co-presence of NNSs/LCSs and free sugar ingredients (FSI), and the number of NNSs/LCSs used in the included foods were computed. Pearson’s χ2 test was used to compare the total number of NNSs and/or LCSs used in food items from different regions. Sucralose (E955) was the most commonly used NNS (1.9%), followed by acesulfame K (E950, 1.6%). Sorbitol was the most commonly used LCS (2.9%). Overall, the use of LCSs was less common compared with NNSs (3.7% vs. 4.5%). The use of different types of NNSs varied substantially between food types. Notably, 20.2% of potato crisps and 15.2% of other crisps or extruded snacks contained at least one NNS and/or LCS. Co-presence of FSIs and NNSs/LCSs were most common in confectionery (15.7%) and snack foods (15.5%). Asian prepackaged foods were more likely to contain NNSs/LCSs (10.1%) compared with those from other regions. To conclude, NNSs/LCSs were used in a wide range of non-diet pre-packaged products which could be a public health concern due to their higher consumption frequencies than “diet” products.

AbstractRecent theory suggests that members of interdependent (collectivist) cultures prioritize in-group happiness, whereas members of independent (individualist) cultures prioritize personal happiness (Uchida et al. Journal of Happiness Studies, 5(3), 223–239 Uchida et al., 2004). Thus, the well-being of friends and family may contribute more to the emotional experience of individuals with collectivist rather than individualist identities. We tested this hypothesis by asking participants to recall a kind act they had done to benefit either close others (e.g., family members) or distant others (e.g., strangers). Study 1 primed collectivist and individualist cultural identities by asking bicultural undergraduates (N = 357) from Hong Kong to recall kindnesses towards close versus distant others in both English and Chinese, while Study 2 compared university students in the USA (n = 106) and Hong Kong (n = 93). In Study 1, after being primed with the Chinese language (but not after being primed with English), participants reported significantly improved affect valence after recalling kind acts towards friends and family than after recalling kind acts towards strangers. Extending this result, in Study 2, respondents from Hong Kong (but not the USA) who recalled kind acts towards friends and family showed higher positive affect than those who recalled kind acts towards strangers. These findings suggest that people with collectivist cultural identities may have relatively more positive and less negative emotional experiences when they focus on prosocial interactions with close rather than weak ties.

Purpose – The purpose of this study is to determine whether Hong Kong is ready for accounting education reform. Design/methodology/approach – The approach for this study is using a Likert-scale questionnaire for the academic institutions, the Hong Kong Institute of Certified Public Accountants and the big four accounting firms, followed by detailed follow-up interviews with each. Findings – There is general agreement among accounting academics and the profession that the Accounting Education Change Commission initiatives should be adopted in Hong Kong. Hong Kong accounting academics in public institutions do not oppose to a balance between teaching and research, but would oppose to an emphasis of teaching over research. This is important as an overemphasis on research could mean less time for teaching and curriculum development. The big four accounting firms are either happy with the way Hong Kong universities have been educating the accounting graduates or have no complaints against them. This is also important as an urge for accounting education reform usually comes from the practitioners as in the USA. Originality/value – The USA was the first country that saw the need for accounting education reform as accounting practitioners felt that curriculum and pedagogical considerations placed heavy emphasis on the technical aspects of accounting at the expense of a general, broad-based education. Similar needs for change were also found in the UK and Australia. As Hong Kong is one of the world’s major financial centres with a large securities exchange, there is a great deal of emphasis on accounting standards, financial reporting, corporate governance, etc., and hence the importance of accounting education. Is Hong Kong ready for the change?

A large under-construction chimney at BALCO Power Plant in central India collapsed on Sep. 23, 2009 under severe stormy weather, causing serious casualties and massive economic losses, while another, similarly built, survived. So far, there has been no strict and scientific analysis on the cause of the accident. In this paper, finite element method is used to simulate the effect of wind loads and the whole collapse procedure based on the investigation of information about the design, the construction, the site related records, etc. The results show that the initial part of the chimney destroyed is the top of the structure (specifically the construction platform and the partial top cylinder wall of the chimney); then the debris from the top fells and crashes the lower part of the structure, eventually leading to the whole structure collapsing. The analysis results are basically consistent with the observation of the debris and the toppling scene and what the witnesses described, and scientifically clarify the actual cause of the chimney collapse. In addition, by comparing the chimney design codes between the USA and China, along with the analysis results, some suggestions are proposed to prevent similar accidents in chimney projects.
