Abstract

Purpose

The purpose of this study was to explore the relationship between environmental factors and building energy consumption of three Leadership in Energy and Environmental Design (LEED)-certified buildings at the Arizona State University, by establishing the relationships of the outside atmospheric temperature and the energy consumed in the building using real-time data generated from different sources.

Design/methodology/approach

K-means clustering analysis is used to calibrate and eliminate unwanted influences or factors from a set of building consumption real-time data. For further statistical analysis, the chi-square is used to verify if the results are ample to prove the findings.

Findings

Few studies have addressed building energy consumption real-time data versus LEED Energy and Atmosphere (EA) credits with the data mining technique (k-means clustering) on most of building performance analyses. This study highlighted that the calibrating energy data are a better approach to analyze energy use in buildings and that there is a relationship between LEED credits’ (EA) Optimize Energy Performance scores and building energy efficiency. However, the energy consumption data alone do not yield useful results to establish the cause and effect relationships.

Originality/value

Although there are several previous research studies regarding LEED building energy performance, this research study focused on the LEED building energy performance versus LEED EA credits versus environmental factors using real-time building energy data and various statistical methods (e.g. K-means clustering and chi-square). The findings provide researchers, engineers and architects with valuable references for building energy analysis methods and supplements in LEED standards.

Abstract

Purpose

Brief introduction on the importance and the need for plastic analysis methods were presented in the beginning section of this review. The plastic method for analysis was considered to be the more advanced method of analysis because of its ability to represent the true behaviour of the steel structures. Then in the following section, a literature analysis has been carried out on the previous investigations done on steel plates, steel beams and steel frames by other authors. The behaviour of them under different types of loading were presented and are under the investigation of innovative new analysis methods.

Design/methodology/approach

Structure member connections also have the potential for plastic failure. In this study, the authors have highlighted a few topics to be discussed. The three topics in this study are T-end plate connections to a square hollow section, semi-rigid connections and cold-formed steel storage racks with spine bracings using speed-lock connections. Connection is one of the important parts of a structure that ensures the integrity of the structure. Finally, in this technical paper, the authors introduce some topics related to seismic action. Application of the Theory of Plastic Mechanism Control in seismic design is studied in the beginning. At the end, its in-depth application for moment resisting frames-eccentrically braced frames dual systems is investigated.

Findings

When this study involves the design of a plastic structure, the design criteria must involve the ultimate load rather than the yield stress. As the steel behaves in the plastic range, it means the capacity of the steel has reached the ultimate load. Ultimate load design and load factor design are the methods in the range of plastic analysis. After the steel capacity has reached beyond the yield stress, it fulfills the requirement in this method. The plastic analysis method offers a consistent and logical approach to structural analysis. It provides an economical solution in terms of steel weight, as the sections designed using this method are smaller compared with elastic design methods.

Originality/value

The plastic method is the primary approach used in the analysis and design of statically indeterminate frame structures.

Abstract

Purpose

Various designs of corrugated webs include trapezoidal, sinusoidal, triangular and rectangular profiles. The increasing use of curved plates has prompted the creation of I-sections made of steel with a corrugated web design. This study aims to examine the effectiveness of an I-beam steel section that features a perforated-triangular web profile.

Design/methodology/approach

In the current study, finite element analysis was conducted on corrugated-perforated steel I-sections using ANSYS software. The study focused on inspecting the design of the perforations, including their shape (circle, square, hexagon, diamond and octagon), size of perforations (80 mm, 100 mm and 120 mm) and layout (the position of web perforation), as well as examining the geometric properties of the section in term of bending, lateral torsional buckling, torsion and shear behavior.

Findings

The study revealed that perforations with diamond, circle and hexagon shapes exhibit good performance, whereas the square shape performs poorly. Moreover, the steel section’s performance decreases with an increase in perforation size, regardless of loading conditions. In addition, the shape of the web perforations can also influence its stress distribution. For example, diamond-shaped perforations have been found to perform better than square-shaped perforations in terms of stress distribution and overall performance. This was because of their ability to distribute stress more evenly and provide greater support to the surrounding material. The diagonal alignment of the diamond shape aligns with principal stress directions, allowing for efficient load transfer and reduced stress concentrations. Additionally, diamond-shaped perforations offer a larger effective area, better shear transfer and improved strain redistribution, resulting in enhanced structural integrity and increased load-carrying capacity.

Originality/value

Hence, the presence of lateral-torsional buckling and torsional loading conditions significantly impacts the performance of corrugated-perforated steel I-sections.

Abstract

Purpose

Since the launch of the Mainland and Hong Kong Closer Economic Partnership Arrangement (CEPA) in 2003, Hong Kong cinema is believed to have confronted drastic changes. Hong Kong cinema is described to be dying, lacking creative space and losing local distinctiveness. A decade later, the rise of Hong Kong – China coproduction cinema under CEPA has been normalized and changed the once pessimism in the industry. The purpose of this paper is to demonstrate how Hong Kong cinema adjusted its production and creation in the first 10 years of CEPA.

Design/methodology/approach

Beginning with a review of the overall development, three paradigmatic cases are examined for reflecting upon what the major industrial and commercial concerns on the Hong Kong – China coproduction model are, and how such a coproduction model is not developed as smooth as what the Hong Kong filmmakers expected.

Findings

Collectively, this paper singles out the difficulties in operation and the limit of transnationality that occur in the Chinese context for the development of Hong Kong cinema under the Hong Kong – China coproduction model.

Originality/value

This is the author’s research in his five-year study of Hong Kong cinema and it contributes a lot to the field of cinema studies with relevant industrial and policy concern.

Abstract

Purpose

Existing studies reflect that traditional teaching–learning relationships between supervisors and graduate students have become disjointed with actuality seriously. In particular, there are practical difficulties in handling many students from coursework-based postgraduate degrees under current university curricula. Therefore, this study aims to explore the relationship between research supervisors and graduate students on social media, which is popular among students.

Design/methodology/approach

This study surveyed 109 graduate students from two majors (population around 100 each) of a university in Hong Kong to explore their information usage for research on social media, related attitudes and their perceived supervisor relationships. The differences between the two majors were also compared.

Findings

The authors’ findings indicated that graduate students were active on social media, and social media has successfully provided effective alternate ways for students to communicate with their research supervisors. Social media could improve relationships between supervisors and research students and among fellow students. Besides education purposes, students also discussed their personal affairs on social media with supervisors, demonstrating enhanced trusted relationships. Graduate students also showed confidence in the further application of social media in higher education. Some differences between respondents from the two programs were also found in terms of communication contents, strengths, personal preferences and purposes for using social media.

Originality/value

Scant studies focus on the relationship between supervisors and graduate students under the current social media environment, especially for students from coursework-based postgraduate degrees. At a deeper level, for the widespread use of social media in the information age, this study explores the specific changes brought about by social media. Therefore, this study is of great theoretical and practical value to graduate education under the current social media environment.

Abstract

There is a broad consensus in the literature that spinoffs tend to create value for shareholders and exhibit positive long‐run excess returns. However, most of the prior studies are confined to the US and the European cases. The spinoff problems in Hong Kong are surprisingly under‐studied despite its important role as a global center of capital formation. In this paper, we find that there is a short‐run value creation for the Hong Kong spinoffs. However, the financial health of the spinoff companies, measured by various financial ratios, tends to deteriorate in the long‐run. In general, Hong Kong spinoffs generate negative returns to investors.

Abstract

Purpose

The purpose of this paper is to understand the corporate sustainability culture of contracting firms, particularly in the Midwest. Many of the local firms operate nationally. The local corporate culture influences their regional offices. Other than convenience, the firms are selected from Midwest since their headquarters are situated in Midwest region and comprises of more number of employees than their other regional offices. This helped the research to approach more contractors for better survey and interview responses. The paper documents the study on existing management and construction practices these contractors adopt on sustainability and examines how their sustainability efforts influence the firms’ performances.

Design/methodology/approach

This research utilized surveys and interviews as the primary means of data collection. The data were collected from survey and interviews with selected companies operating in the Midwest region of the USA. One of the companies also operates offices across the country. Data from the interviews and surveys were analyzed using statistical analysis system software application. χ2 analysis, particularly the frequency procedures using the Cochran-Mantel-Haenszel (CMH) method was the primary analysis method used to study the relationships between different factors. The CMH method compares the association between and within two groups and permits adjustments of the control variables.

Findings

The findings of this paper include the results from various Midwest commercial building contractors. The results on different aspects of sustainable practices and their success rates among the contractors are determined and discussed, and future scope of improvements are mentioned at the conclusion of this paper.

Research limitations/implications

In summary, sustainable business practices are beneficial to society and favorable for the construction business. Embracing sustainable business practices has a positive impact on firm strategic performance for commercial building contractors through employee satisfaction, project opportunities, and market advantage. Sustainable business practices extend into the lives of individuals involved which exceedingly impacts society. The construction industry has advanced sustainability efforts, but there is a long way to go on the journey to being better stewards of the environment and resources.

Originality/value

A rival theory became apparent during the investigation that a new building consolidating all local company employees could have an impact on firm strategic performance. Third, this paper is confounded by a great recession that made project opportunities and revenue considerations analysis problematic. Some information regarding these aspects were helpful; however, expanding this paper during a more stable and typical economic period could provide additional insight.

Abstract

Purpose

The purpose of this paper is to investigate how supply chain management (SCM) practices and knowledge management (KM) capabilities affect firm performance. This study was conducted in the Asia Pacific region, which had not been examined before.

Design/methodology/approach

A three‐phase statistical analysis which comprised phase one (convergent validity, reliability, and discriminant validity), phase two (mediated regression analysis) and phase three (path analysis) was used to analyze the data.

Findings

The results from this paper have shown that the implementation of SCM practices will interact with KM capabilities to influence firm performance.

Research limitations/implications

The proposed model does not consider firm performance from multiple perspectives. In addition, the use of longitudinal data would be more useful to examine how changes in certain variables affect performance.

Practical implications

These findings provide important insights for managers to understand the disposition of the firm to better leverage internal capability (knowledge), by exploiting relationships with supply chain partners.

Social implications

This paper has extended knowledge in the mainstream management and provides valuable clues on how to improve organizational effectiveness, which is the crux of management.

Originality/value

The paper is among the first empirical works that specifically investigate the relationships between KM and SCM; thus this paper fills an important gap in the supply chain literature.

Abstract

Purpose

National identification among young people and the issues about how national education should be conducted have been the significant topics when the Hong Kong Special Administrative Region was entering its third decade of the establishment. This paper was written based on data the authors obtained upon participation in a project organized by the Centre for Catholic Studies of the Chinese University of Hong Kong. The project was carried out after the official curriculum, known as the Moral and National Education Curriculum Guide, was shelved due to popular resentment. The project aimed at capturing the timely opportunity for substantial resources available for school-based operation of moral and national education and developing an alternative curriculum about teaching national issues and identification for Catholic Diocese and Convent primary schools to adopt. This paper aims to investigate the nature of this Catholic Project and examines the extent to which it is a counterhegemonic project or one for teaching to belong to a nation (Mathews, Ma and Lui, 2007). It assesses the project’s possible contribution to citizenship and national education in Hong Kong, since the withdrawal of the Moral and National Education Curriculum Guide.

Design/methodology/approach

The authors of this paper worked in an education university of Hong Kong and were invited to be team members of this Catholic Project. The role comprised proposing topics for teacher training, conducting seminars, giving comments to teaching resources, observing and giving feedback to schools that tried out the teaching and designing/implementing an evaluative survey and conducting follow-up interviews with involved parties such as teachers and key officials of the Catholic Centre. Given this, the research involved can be perceived as action research. This paper was written up with both the qualitative and quantitative data the authors collected when working the project.

Findings

This paper reported a Catholic citizenship training project with the focus on a Catholic school project on preparing students to understand the nation by learning national issues analytically. The ultimate goal was to ensure teachers in Catholic primary schools could lead the students to examine national issues and other social issues from the perspective of Catholic social ethics. Though the project arose after the failure of the government to force through its controversial national education programme, this paper found that instead of being an alternative curriculum with resistance flavour, the project was basically a self-perfection programme for the Catholic. It was to fill a shortfall observed of Catholic schools, namely, not doing enough to let students examine social and national issues with Catholic social ethics, which, indeed, had a good interface with many cherished universal values. In the final analysis, the project is not a typical national education programme, which teaches students to belong to a nation but an innovative alternative curriculum transcending the hegemony-resistance ideological tensions as advanced by western literature (for example, Gramsci, 1971; Freire, 1970; and Apple, 1993).

Originality/value

The paper contributes to the literature of Hong Kong studies and citizenship education studies. The results of such an innovative endeavour, which captures and capitalizes the opportunity and resources for developing a national education curriculum in school-based manner. Attention was paid to the endeavour’s nature and its possible contribution to the knowledge, policies and practices of citizenship and national education in Hong Kong amidst deep social transformations. In particular, the paper can add to the specific literature about Hong Kong’s citizenship and national education development since the withdrawal of the Moral and National Education Curriculum Guide. Using an empirical example of Asian schooling and society, analysis of this paper illustrates the way in which development of an alternative curriculum is more innovative and interesting, transcending the hegemony-resistance ideological tensions.

Abstract

Purpose

The purpose of this study was to explore the possibilities of utilization of chicken meat in the preparation of chicken meat noodles and subsequent storage at ambient temperature.

Design/methodology/approach

Chicken meat was incorporated at the levels, viz., 0 and 40 per cent, replacing refined wheat flour in the formulation. Proximate composition, pH, water activity (aw), free fatty acid (FFA), thio-barbituric acid reacting substances (TBARS), water absorption index (WAI), water solubility index (WSI), textural profile analysis (TPA), microbial quality and sensory evaluation were assessed at 10-day interval up to 30 days.

Findings

Moisture, aw, TBARS, FFA, WAI, crispiness, total plate count (TPC) and yeast and mould values increased significantly (p < 0.05), whereas, fibre, ash, pH, WSI, hardness, work of shearing and sensory attributes showed significant (p < 0.05) decrease. However, all these parameter, viz., microbial quality, TBRS, FFA and sensory attributes, were within the acceptable limit during the entire storage study.

Research limitations/implications

Quality of the products may be improved by the incorporation of some natural antioxidant and antimicrobial agent in chicken meat noodles.

Originality/value

Consumption and demand of the noodles is increasing due to its easy preparation and taste; however, it is poor in nutritive quality. Incorporation of the chicken meat in the noodles improves the nutritive values and sensory attributes, which is important for the marketability of the meat products. The keeping quality of chicken meat noodles was comparable to the control noodles at ambient temperature up to 30 days. Noodles industry provides an alternate sector for the utilization of meat and enhancing its overall quality attributes.
