Abstract

Rural residential energy consumption accounts for 46.6% of total building-related energy consumption of China. In Northeast China, energy consumption for space heating represents a significant proportion of total rural residential energy consumption and has reached 100 million tce (tons of standard coal equivalent), or more than 60% of total household energy consumption. In terms of energy consumption per square meter of gross floor area, rural residential energy consumption for heating is more than that of cities (20kgce/m2). However, the average indoor temperature of most rural residence is below 10°C, much less than that in cities (18°C). Hence, it is an important task for Chinese energy saving and emission reduction to reduce rural residential energy consumption, while enhancing indoor thermal comfort at the same time.

Restricted by local technology and low economic level, rural residences currently have poor thermal insulation resulting in severe heat loss. This paper reports on research aimed at developing design strategies for improving thermal insulation properties of rural residences with appropriate technology. A field survey was conducted in six counties in severe cold areas of Northeast China, addressing the aspects of indoor and outdoor temperature, humidity, internal and external surface temperature of building envelop enclosure, and so on.

The survey data show the following:

1. Modern (after 2000) brick-cement rural residences perform much better than the traditional adobe clay houses and Tatou houses (a regional type of rural residence in Northeast China – see figure A) in overall thermal performance and indoor thermal comfort;

2. Among the traditional residential house types, adobe clay houses have better heat stability and thermal storage capacity than Tatou houses;

3. Applying an internal or external thermal insulation layer can greatly improve rural residential thermal insulation properties, and is an economical and efficient solution in rural areas;

4. In terms of roofing materials, tiled roofs show much better thermal insulation properties than thatch roofs;

5. Adopting passive solar techniques can form a transition space (greenhouse) against frigid temperatures, resulting in interior temperatures 5.91°C higher than the outside surroundings. It is evident that local passive solar room design offers significant heat preservation effects and lower cost ($12/m2), embodies the ecological wisdom of rural residents, and is therefore important to popularize.

The above experimental results can provide guidance in energy conservation design for both self-built residences and rural residences designed by architects. In addition, the results can also provide experimental data for energy-saving studies for rural residences in China.

Abstract

Purpose

The purpose of this paper is to explore the relationship between the acquisition of an ISO 9000 certification and the overall financial performance of the certified firms. More specifically, the study proposes a multidimensional conceptual framework, including “customers’ demand”, “ISO adoption”, “operation efficiency”, “market efficiency” and “overall financial performance”. Such a multidimensional approach has randomly been explored in the existing literature, making the examination of the proposed conceptual framework an interesting research topic.

Design/methodology/approach

The proposed conceptual framework was tested on a sample of Greek ISO 9000-certified companies of various economic sectors. Quality managers were used as key respondents. The final sample consisted of 168 companies. The reliability and the validity of the questionnaire were thoroughly examined. Empirical data were analyzed using the structural equation modelling technique. The findings are based on the 2000 version of the ISO series, which is generally accepted and has widespread use, as it has eliminated most of the disadvantages of the 1994 version. The present study is empirical (it is based on primary data), explanatory (examines cause and effect relationships), deductive (tests research hypotheses) and quantitative (includes the analysis of quantitative data collected with the use of a structured questionnaire).

Findings

The findings of the study provide strong evidence that ISO 9000 implementation is highly associated with improvements in overall financial performance. Moreover, it was found that ISO implementation is directly associated with significant improvements in quality awareness, operations execution, market share, customer satisfaction and sales revenue. Finally, customers’ demand was not found to be the most important motivation for implementing an ISO certification. Rather, it seems that companies seek for quality improvement due to internal motives.

Research limitations/implications

A limitation stemming from the implemented methodology is the use of self-report scales to measure the constructs of the proposed model. Moreover, the present paper lacks a longitudinal approach, since it is cross-sectional and provides a static picture of ISO implementation.

Practical implications

The paper makes an analytical effort in order to point out areas that companies should emphasize in order to successfully implement ISO 9000 and, therefore, harvest its potential benefits. Certain practical implications are offered in the final part of the paper.

Originality/value

The paper proposes an enhanced conceptual framework that examines vital issues concerning the successful implementation of ISO 9000, thus, providing valuable outcomes for decision makers and academics. Moreover, the results of the study may be generalized in other developed countries whose economy faces similar significant challenges as Greece.

Abstract

Purpose

Soy protein has been considered as a renewable and environmentally friendly source of adhesives. The purpose of this paper is to investigate a new approach for making a soy protein adhesive modified by SiO2 nanoparticles.

Design/methodology/approach

The objective of this investigation was to evaluate the adhesive properties by determining the viscosity, wettability and shear strength of soy protein adhesive. The effects of nano‐SiO2 content, wood surface roughness and processing pressure on shear strength between soy protein adhesive and wood were investigated. Four nano‐SiO2 contents (0, 0.5, 1 and 2 percent), two wood surface roughness (40 and 280 grits), and two processing pressure (1 and 2 MPa) were tested. Adhesive performance was evaluated based on the maximum force required for shearing the adhesive bond between cherry wood pieces.

Findings

The modified soy protein adhesives by SiO2 nanoparticles showed a significant enhancement in dry strength with nano‐SiO2 content of 1 percent. The mechanism appears to be related to the increased interaction between adhesive and wood and the elimination of voids on the wood surface by SiO2 nanoparticles.

Research limitations/implications

The adhesive resins used in the present context was soy protein isolate, not from commercially available soy flour. The wet strength was not satisfactory. Further study is needed to solve this problem.

Practical implications

The method developed provided a simple and practical solution to improving the shear strength of soy protein adhesives.

Originality/value

The enhancement method for adhesion strength of soy protein was novel and could find numerous applications in wood industry, avoiding formaldehyde emission and reducing the dependence on petroleum products.

Abstract

Purpose

Spinning triangle is a critical region in the spinning process of staple yarn, which geometry influences the distribution of fiber tension and determines the qualities of yarn directly. Therefore, the purpose of this paper is to investigate the fiber tension distribution at the twist point.

Design/methodology/approach

First, one theoretical model of fiber tension distributions at the twist point is given according to the motion law of fibers in the spinning triangle. Then, one calculation method of fiber tension at the twist point is given by two steps. First, the initial tension of each fiber at the front nip line caused by the yarn load should be calculated according to the models obtained based on the principle of minimum potential energy. Second, the fiber tensions at the twist point can be calculated using the obtained model in this paper. Finally, as an application of the proposed method, spinning triangles of a modified ring spinning system with a pair of offset device which can change the horizontal offset of the twist point to the symmetric axis of nip line of the spinning triangle continuously are studied. The fiber tension distributions are simulated numerically.

Findings

It is shown that the fiber tension distributions at the twist point can be determined by fiber feeding into and out the spinning triangle speed, the initial tension of each fiber at the front nip line, fiber tensile Young’s modulus and cross-sectional area, the number of fibers at spinning triangle and the individual fiber angle with the center fiber. The spinning experiment shows that taking appropriate right or left offset of the spinning triangle can help to improve the spun yarn qualities.

Originality/value

In this paper, the fiber tension distribution at the twist point is investigated. One theoretical model of fiber tension distributions at the twist point is given according to the motion law of fibers in the spinning triangle first. Then, one calculation method of fiber tension at the twist point has been given under the assumption that the initial tension of each fiber at the front nip line is caused by the yarn load.

Abstract

Purpose

The purpose of this paper is to examine the complex relationships between common bond attachment, common identity attachment, self-esteem and virtual community citizenship behavior (VCCB). This study identifies two broad categories of VCCB: citizenship behaviors directed toward benefitting other individuals (VCCBI) and citizenship behaviors directed toward benefitting the virtual community (VCCBC).

Design/methodology/approach

The authors apply partial least squares structural equation modeling to test the hypotheses, using a sample of 388 valid responses.

Findings

The results indicate that common bond attachment and common identity attachment have a significant effect on self-esteem, which, in turn, has a significant effect on VCCBI and VCCBC. The results also indicate that common bond attachment has a significant effect on VCCBI, and that common identity attachment has a significant effect on VCCBC.

Originality/value

This study contributes to a better understanding of VCCBs through common identity and common-bond theory, social identity theory and the stimulus-organism-response framework.

Abstract

Since China initiated its “go global” policy that promotes its overseas investment, China’s Outward Foreign Direct Investment (OFDI) has increased almost twenty times during the last 10 years, reaching $55.9 billion in 2008. The issue of internationalization of Chinese OFDI has attracted increasing attention of researchers from a business perspective. This article systematically reviews the previous studies on overseas investments by Chinese MNEs and discusses the characteristics of Chinese internationalization behavior at both firm level and country level. The internationalization of Chinese companies cannot be understood as a simple game of “catch up” with established MNEs, and more firm‐level empirical studies should be carried out on how these characteristics influence firms’ strategic decisions.

Abstract

Recent research on immersive experiences in online environments for higher education has attributed a fundamental role to two distinct yet connected psychological phenomena: the feelings of being virtually present in the education environment, often simply called presence, and peak episodes of flow. The authors conceptually delimitate these two psychological facets of e-learners’ experiences and examine their interplay. The authors show how flow episodes are elicited by students’ sense of control over the online education environment, their attention being focussed on the learning tasks, and their feelings of being physically placed in the online education setting. Also, the interactivity created by the online education environment evokes an e-learner’s imagery, which in turn triggers presence feelings and episodes of flow. The authors further show that, although presence and flow are triggered by some common antecedents, they differ in the object of the individual’s immersion, and that presence feelings facilitate flow. Moreover, the authors provide practical recommendations for higher education institutions, policy makers and the academic and information and communication technology community involved in e-learning, to make sure e-learner experiences reach their fullest potential.

Abstract

Purpose

The paper aims to investigate the effect of Degussa P-25 Titanium Dioxide (TiO2) nanoparticles on hydrophobicity and self-cleaning ability as a single organic coating on glass substrate.

Design/methodology/approach

Two methods have been used to enhance the hydrophobicity on glass substrates, namely, surface modification by using low surface energy isooctyltrimethoxysilane (ITMS) solution and construction of rough surface morphology using Degussa P-25 TiO2 nanoparticles with simple bottom-up approach. The prepared sol was applied onto glass substrate using dip-coating technique and stoved in the vacuum furnace 350°C.

Findings

The ITMS coating with nano TiO2 pigment has modified the glass substrate surface by achieving the water contact angle as high as 169° ± 2° and low sliding angle of 0° with simple and low-cost operation. The solid and air phase interface has created excellent anti-dirt and self-cleaning properties against dilute ketchup solution, mud and silicon powder.

Research limitations/implications

Findings will be useful in the development of self-cleaning and anti-dirt coating for photovoltaic panels.

Practical implications

Sol method provides the suitable medium for the combination of organic–inorganic network to achieve high superhydrophobicity and optimum self-cleaning ability.

Originality/value

Application of blended organic–inorganic sol as self-cleaning and anti-dirt coating film.

Abstract

Purpose

The purpose of this paper is to determine the value of I‐Ching (also called Book of Changes), the ancient Chinese book of wisdom, which has been used for thousands of years to help people make decisions in daily life. Recently, eastern and western scholars have begun discussing how to apply the wisdom of I‐Ching to the field of business administration, particularly decision‐making practices.

Design/methodology/approach

A content analysis method was adopted to uncover possible modern management decision‐making constructs. The single words approach did not find frequently appearing words that integrated decision‐making constructs in the context of I‐Ching. Further uncovering I‐Ching's administrative decision‐making approach, the managerial decision‐making model of I‐Ching is explained, including the premises, the decision contingencies, and the decision process.

Findings

By using an academic comparative analysis method, as it applies to managerial decision making, I‐Ching's early management decision‐making model is subsequently compared with western management decision models, which include rational decision making, bounded‐rationality decision making, intuitive decision making, implicit favorite decision making, and garbage‐can decision making.

Research limitations/implications

The majority of scholars that study I‐Ching focus on “practice divination” research, paying attention to the interpretation or critique of the text only. Unfortunately, related literature based upon a social science research foundation is limited.

Originality/value

The value of I‐Ching was determined to lie in allowing flexibility in the decision‐making process.
