Does altruism matter on online group buying? Perspectives from egotistic and altruistic motivation
Authors: Shiau Wen-Lung , Chau Patrick Y.K. 
Published: August 2015

Purpose– The purpose of this paper is to identify whether altruistic motivation is a significant factor in online group buying and to examine the effects of altruistic and egotistic motivation on online group buying intention through the psychological processes of trust and satisfaction.Design/methodology/approach– A field study on Ihergo (www.ihergo.com/) was chosen because it is the largest online group buying marketplace in Taiwan. An online survey method was used to collect data. Returned questionnaires numbered 302 responses with 20 incomplete data, resulting in 282 valid responses for data analysis. Collected data were analyzed using structural equation modeling.Findings– The findings of the study shows that altruism is relevant to online group buying, and trust and satisfaction have significantly positive effects on online group buying intention. The results emphasize that altruism, reciprocity, and reputation of motivations are significantly positive predictors of trust. Altruism and reciprocity have significantly positive effects on satisfaction, whereas reputation does not.Research limitations/implications– Altruism, reciprocity, and reputation represent three key elements of online group buying behavior. Integration of the altruism, reciprocity, and reputation results in a better explanation on online group buying intention through the psychological process, trust, and satisfaction. This study extends the value of online group buying and sheds light on the potential effects of altruistic and egotistic motivation on online group buying intention.Practical implications– Online group buying is more complex than individual online shopping and is not easy to fulfill customer requirements. To satisfy online group buying, e-vendors might provide altruistic activities, enhance reciprocal services and products, develop better reputation mechanisms, and present an easier approach to encourage online group buying on the web site.Originality/value– To the best of the knowledge, this is first paper to examine the effects of altruism on online group buying. The contribution of this study draws attention to the altruistic value of electronic commerce, by theorizing and validating the effects of altruistic and egotistic motivation on online group buying intention through psychological processes (trust and satisfaction).

Authors: Näsi Matti , Räsänen Pekka , Hawdon James , Holkeri Emma , Oksanen Atte 
Published: August 2015

Purpose– Trust is one of the key elements in social interaction; however, few studies have analyzed how the proliferation of new information and communication technologies influences trust. The authors examine how exposure to hate material in the internet correlates with Finnish youths’ particularized and generalized trust toward people who have varying significance in different contexts of life. Hence, the purpose of this paper is to provide new information about current online culture and its potentially negative characteristics.Design/methodology/approach– Using data collected in the spring of 2013 among Finnish Facebook users (n=723) ages 15-18, the authors measure the participants’ trust in their family, close friends, other acquaintances, work or school colleagues, neighbors, people in general, as well as people only met online.Findings– Witnessing negative images and writings reduces both particularized and generalized trust. The negative effect is greater for particularized trust than generalized trust. Therefore, exposure to hate material seems to have a more negative effect on the relationships with acquaintances than in a more general context.Research limitations/implications– The study relies on a sample of registered social media users from one country. In future research, cross-national comparisons are encouraged.Originality/value– The findings show that trust plays a significant role in online setting. Witnessing hateful online material is common among young people. This is likely to have an impact on perceived social trust. Hateful communication may then impact significantly on current online culture, which has a growing importance for studying, working life, and many leisure activities.
Relationship or contract? Exploring the key factor leading to IT outsourcing success in China
Authors: Qi Cong , Chau Patrick Y.K. 
Published: August 2015

Purpose– Effective management of IT outsourcing continues to be a challenge to organizations today. Organizations in China suffer from even bigger problems than other regions of the world. The IT outsourcing market is in its infancy and the outsourcing practice is still at its initial stage. Regarding to the outsourcing management issues, the literature has explored the role of either the relationship or contract in governing IT outsourcing success. However, few efforts have been paid to investigate the effects of both relationship and contract on IT outsourcing success from a holistic view. The paper aims to discuss these issues.Design/methodology/approach– This study develops a conceptual model and empirically tests it through a cross-sectional survey conducted in five big cities of Mainland China.Findings– The data analysis results identified the dimensionalities of relationship, contract and IT outsourcing success and proved the causal relationships between these three constructs.Originality/value– This research re-emphasizes the importance of relationship in IT outsourcing success and the fundamental role of contract in developing a sound relationship. It also gives some implications on how to evaluate IT outsourcing success in China, an emerging market for IT outsourcing.
Evolution of technology perceptions over time
Authors: Immonen Mika , Sintonen Sanna 
Published: August 2015

Purpose
– As the information society further develops, electronic services are created and physical distribution networks become sparse, it is important to analyse the determinants that inhibit or facilitate the ability to use these services. By focusing on the perceived behavioural control of computers, the purpose of this paper is to analyse how perceived physical restrictions, computer anxiety and ease of use influence the perceptions of control.

Design/methodology/approach
– The authors examined older consumers (aged 60-79) in two cross-sectional studies conducted through mail surveys in 2004 and 2012. Randomized samples (n=1,000 in 2004 and n=3,000 in 2012) were drawn from the Finnish Population Register. The empirical research utilized structural equation modelling through multi-group analysis to explore the differences in the interrelationships between physical restrictions, computer anxiety, perceived ease of use and perceived behavioural control.

Findings
– The results indicate that perceived behavioural control is directly influenced by ease of use and indirectly influenced by physical restrictions and computer anxiety. The eight-year time gap moderated only the relationship between physical restrictions and ease of use. Development seems to have been favourable, and device-related restrictions do not decrease ease of use as much as previously reported.

Originality/value
– The present study starts a new discussion on how time moderates the relationship of technology perceptions in behavioural models that have been used to predict behavioural intent.
GSCM: practices, trends and prospects in Indian context
Authors: Soda SHEETAL , Sachdeva Anish , Garg Rajiv Kumar 
Published: August 2015

Purpose
– Environmental friendliness, in context of industrial operations, is an issue that has evoked much interest among environmentalists, governments, academicians and other sections of society in recent times. The said development has been more profound and broad-based in developed economies of the world, though, the trend is catching fast in developing countries, as well. Green Supply Chain Management (GSCM) is a management technique that aims to make a supply chain eco-friendly, without diluting the organizational objectives. The purpose of this paper is to investigate the scale of adoption and implementation of GSCM practices in the context of Indian industries.

Design/methodology/approach
– The investigation used literature review approach to determine the current status of implementation of GSCM by Indian industry, and associated aspects of the same. Literature pertaining to the subject in context of non-Indian industries has also been studied for the purpose of rudimentary knowledge on the management concept, as well for comparing the measures taken by foreign-based companies with Indian ones.

Findings
– The study shows that in general, Indian companies are lacking on the front of adoption and implementation of GSCM measures in their supply chains. Though, certain companies are showing appreciable enthusiasm for the eco-friendly concept, the same does not apply to majority of the Indian enterprises, owing to a multitude of factors. GSCM has the potential to drive economic gains, and can act as a big motivator for companies to go green. As India leaps towards higher levels of industrialization and economic growth, GSCM becomes more of a necessity rather than an option for Indian companies to survive the competition.

Practical implications
– Findings from this study helps in discerning the present status of GSCM in the country, and assess the same in comparison to that of developed countries. The findings will also help the firms to have a greater understanding of their current standing and the possible gains that can accrue by adoption of GSCM practices in real. The philosophy, stance and endeavours of government with respect to GSCM has also been spelt out in the paper. The paper contributes to the literature by providing empirical evidence on various aspects of GSCM in the country and the trajectory that it will chart in future.

Originality/value
– The paper though, brings forth the findings of other researches on the subject of GSCM practices in India in a consolidated manner, yet its value is reflected in the cohesive manner in which contrary findings have been analysed to present a comprehensive and holistic picture of GSCM implementation in India. An attempt has been made not only to assess the inputs of individual firms, but also of government and other stakeholders in their efforts to make supply chains more environment friendly.

Regional framework conditions for future careers related to transport and mobility
Authors: David Alexandra , Terstriep Judith 
Published: August 2015

Purpose– In the search for appropriate solutions to cope with ever increasing road traffic, cities and urban agglomerations across Europe are placing great emphasis on new transport and mobility solutions, and electric mobility in particular. Being located at the intersection of the three constituent sectors automotive, information and communication technologies and green energy, electric mobility is perceived as future-oriented sector. Innovation in the sector not only requires the collaboration and exchange of knowledge, but also an increase in skilled workforces and distinct job qualifications. These demands emerge, on the one hand, through the electrification of cars, which results in structural changes in the entire value chain. On the other hand, growing customer and service orientation further accelerate such developments. So far, the knowledge about the concrete demands for engineers as knowledge carriers and innovation driver is rather scarce. To shed some light on this issue, the purpose of this paper is to discuss companies’ altered demand for engineers in electric mobility and the role of networks (e.g. clusters).Design/methodology/approach– This paper discusses two regions characterised as traditional automotive regions (Stuttgart in Germany and Alsace/Franche-Comté in France) and the shift in demands of the companies in these regions using the engineering workforce as an example. Electric mobility related companies were surveyed and asked about their current need of engineers. In addition, the survey investigated the companies’ ways of recruiting engineers, their spatial scope of search for employees and the skills and thematic courses needed to solve the lack of qualifications. The survey results are discussed against a background of regional framework settings and influencing factors of both the regions analysed.Findings– This paper finds that there is a shift in qualification demands of engineers involved in the sector of transport and mobility. Initiated by the processes along the entire value chain, new skills are required by companies. The current engineers are asked to mix their technical know-how with service orientation and knowledge of new markets.Originality/value– The world is becoming increasingly mobile. Within the last decades, the number of daily commuters has expanded producing high capacities of road traffic. This has brought several challenges for cities and regions. To face them new transport and mobility concepts are of key importance for cities and regions. Along these lines, well-skilled human capital in the form of engineers is needed to expand the concepts with their skills and knowledge.

Authors: Said Samia M 
Published: August 2015

Purpose
– The purpose of this paper is to investigate the effect of rotation and a magnetic field on the wave propagation in a generalized thermoelastic problem for a medium with an internal heat source that is moving with a constant speed.

Design/methodology/approach
– The formulation is applied to a generalized thermoelastic problem based on the three-phase-lag model and Green-Naghdi theory without energy dissipation. The medium is a homogeneous isotropic thermoelastic in the half-space.

Findings
– The exact expressions of the displacement components, temperature, and stress components are obtained by using normal mode analysis.

Originality/value
– Comparisons are made with the results predicted by the two models in the absence and presence of a magnetic field as well as a rotation. A comparison also is made with the results predicted by the two models for two different values of an internal heat source.
A flexibility method for structural damage identification using continuous ant colony optimization
Authors: Daei Maryam , Mirmohammadi S. Hamid 
Published: August 2015

Purpose
– The interest in the ability to detect damage at the earliest possible stage is pervasive throughout the civil engineering over the last two decades. In general, the experimental techniques for damage detection are expensive and require that the vicinity of the damage is known and readily accessible; therefore several methods intend to detect damage based on numerical model and by means of minimum experimental data about dynamic properties or response of damaged structures. The paper aims to discuss these issues.

Design/methodology/approach
– In this paper, the damage detection problem is formulated as an optimization problem such as to obtain the minimum difference between the numerical and experimental variables, and then a modified ant colony optimization (ACO) algorithm is proposed for solving this optimization problem. In the proposed algorithm, the structural damage is detected by using dynamically measured flexibility matrix, since the flexibility matrix of the structure can be estimated from only the first few modes. The continuous version of ACO is employed as a probabilistic technique for solving this computational problem.

Findings
– Compared to classical methods, one of the main strengths of this meta-heuristic method is the generally better robustness in achieving global optimum. The efficiency of the proposed algorithm is illustrated by numerical examples. The proposed method enables the deduction of the extent and location of structural damage, while using short computational time and resulting good accuracy.

Originality/value
– Finding accurate results by means of minimum experimental data, while using short computational time is the final goal of all researches in the structural damage detection methods. In this paper, it gains by applying flexibility matrix in the definition of objective function, and also via using continuous ant colony algorithm as a powerful meta-heuristic techniques in the constrained nonlinear optimization problem.

Authors: Sepe Raffaele , Armentani Enrico , Pozzi Angela 
Published: August 2015

Purpose
– The major objectives of this study are the engineering development and the structural analysis with finite element method (FEM) of a refrigerated container having a passive equipment and a remote control system to carry both fresh (+4°C÷±1°C) and frozen (−18°C÷−20°C) goods. The purpose of this paper is to offer some solutions to the many disadvantages of using phase change material (PCM) to refrigerate the insulated container for transporting both fresh and frozen goods.

Design/methodology/approach
– In order to transport both fresh products (+4°C÷±1°C) and frozen products (−18°C÷−20°C), the PCM elements are filled with one eutectic liquid only, so as to avoid problems related to filling and emptying the eutectic plates, and to plate corrosion. Moreover, specially shaped air ducts and a cool flow control system are designed to maintain a uniform circulation of cool air and constant humidity values. All the structures of the container are correctly designed by means of FEM calculations to assure that all the structural, safety standards parameters are satisfied.

Findings
– An innovative refrigerated container with PCM and a remote control system used to transport both fresh (+4°C÷±1°C) and frozen (−18°C÷−20°C) products, in which it is possible to maintain the temperature values for almost seven days, has been considered here. Many disadvantages due to the use of PCM have been eliminated. It is possible to maintain a uniform circulation cool air and humidity values within the design parameters by means of fans; moreover, this container is light and environmentally friendly. All structures of the container are designed using FEM.

Originality/value
– This paper presents a refrigerated container with passive equipment and a remote control system to carry both fresh (+4°C÷±1°C) and frozen (−18°C÷−20°C) goods in which it is possible to maintain the temperature values necessary for almost seven days. The container is equipped with a remote control system powered by photovoltaic panels which works in real time, is capable of giving information about the environmental parameters set in it and monitors the state of products by means of a network of sensors. Furthermore, the remote control system can send information about the position of the container to a remote control centre. The relevant structural conditions are numerically (FEM) evaluated and reported.
Modeling and analysis of free vibrations in thermoelastic hollow spheres
Authors: Sharma Nivedita 
Published: August 2015

Purpose– The purpose of this paper is to present a model to analyze free vibrations in a transradially isotropic, thermoelastic hollow sphere subjected to stress free, thermally insulated or stress free, isothermal and rigidly fixed, thermally insulated or rigidly fixed, isothermal boundary conditions.Design/methodology/approach– The potential functions along with spherical wave solution have been used to reduce the system of governing partial differential equations to a coupled system of ordinary differential equations in radial coordinates after employing non-dimensional quantities. Matrix Frobenius method of extended power series has been employed to obtain accurate solution of coupled differential equations in terms of radial coordinates. The mathematical model of the considered problem has been solved analytically to obtain the characteristics equations after imposing the appropriate boundary conditions at the outer and inner surfaces of the hollow sphere. The characteristic equations which govern various types of vibration modes expected to exist have been derived in the compact form. The special cases of spheroidal and toroidal modes of vibrations have been deduced from the characteristic equations and discussed.Findings– The toroidal mode has been found to be independent of temperature change. The magnitude of lowest frequency and damping factor are significantly affected in the presence of thermal field and increase with an increase in the spherical harmonics in addition to geometry of the structure.Originality/value– The matrix Frobenius method has been used to develop analytical solutions and functional iteration technique to carry out numerical simulations of such structures for the first time. The simulated results are presented graphically and compared with the available literature.

Published: August 2015

Purpose
– The purpose of this paper is to discuss applied statistical design of experiment (DOE) to optimize the process of dyeing in natural fiber through the multidisciplinary photoacoustic technique.

Design/methodology/approach
– First, the spectroscopy analysis of the dyestuffs was carried out based on the 23 factorial design. Second, the DOE was utilized to find which process variables were most significant in the absorption band’s intensity of the dye. Finally, the impregnation optimization of fiber was carried out based on response surface methodology.

Findings
