Abstract

Purpose

Consumer behaviors in internet are changing over time. The purpose of this paper is to propose and examine a research model that describes the repurchase behavior for the legal and paid music products of physical genre and online genre. The consumption value theory is used to develop the research model. Comparison of physical genre with online genre is presented. Implications and suggestions are addressed.

Design/methodology/approach

The research model is examined empirically. The research targeted music product consumers who had purchasing experience in the past one year. The research results are obtained, and the findings are revealed on the basis of 728 valid music product consumers.

Findings

The functional, emotional and epistemic value are the significant driving factors, though it shows a limited distinction for the two types. In comparing of the concepts of designed functional value, physical music consumers tend to have a stronger enthusiasm in music consumption. Social value and conditional value are not the predicators of repurchase satisfaction, implying that the music consumption is self-oriented for any normal amusement. The epistemic value shows significant on all levels of significance for the physical type, whereas insignificant if a = 0.01 for the type of online.

Originality/value

The research model is applied for the two contrariety product types, and to make a comparison, trying to understand the reasons why music fans are still willing to spend money on music products and what factors make them choose between product genres. After fluctuation and alternation of the music industry within this decade, this research provides a reference and correlated results for the future studies for the related studies, especially for the prosperous physical parallel imports items and online music.

Abstract

Examines the fifthteenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract

Purpose

Engineering design optimization involving computational simulations is usually a time-consuming, even computationally prohibitive process. To relieve the computational burden, the adaptive metamodel-based design optimization (AMBDO) approaches have been widely used. This paper aims to develop an AMBDO approach, a lower confidence bounding approach based on the coefficient of variation (CV-LCB) approach, to balance the exploration and exploitation objectively for obtaining a global optimum under limited computational budget.

Design/methodology/approach

In the proposed CV-LCB approach, the coefficient of variation (CV) of predicted values is introduced to indicate the degree of dispersion of objective function values, while the CV of predicting errors is introduced to represent the accuracy of the established metamodel. Then, a weighted formula, which takes the degree of dispersion and the prediction accuracy into consideration, is defined based on the already-acquired CV information to adaptively update the metamodel during the optimization process.

Findings

Ten numerical examples with different degrees of complexity and an AIAA aerodynamic design optimization problem are used to demonstrate the effectiveness of the proposed CV-LCB approach. The comparisons between the proposed approach and four existing approaches regarding the computational efficiency and robustness are made. Results illustrate the merits of the proposed CV-LCB approach in computational efficiency and robustness.

Practical implications

The proposed approach exhibits high efficiency and robustness in engineering design optimization involving computational simulations.

Originality/value

CV-LCB approach can balance the exploration and exploitation objectively.

Abstract

Based on the normalized variable diagram, the weakness of the Gaskell and Lau's convective boundedness criterion (GL‐CBC) is revealed by numerical example. By careful consideration of the smoothness of the normalized variable variation pattern, more rigorous constraints on the interface value interpolation are found. A new CBC is thus proposed, whose feasibility and correctness are demonstrated by the inspection of ten existing bounded schemes and a numerical example.

Abstract

Purpose

The purpose of the study is to investigate and reveal this relationship of various engineering demand parameters (EDPs) of this structural type and intensity measures (IMs) under intra-plate earthquakes.

Design/methodology/approach

The nonlinear finite element model used was calibrated first to the existing results of the shaking table test to verify the modeling technique.

Findings

This paper investigated the relationship between intensity measures and various engineering demand parameters of cable-stayed bridges using intra-plate earthquakes. The correlation analysis and Pearson coefficient are used to study the correlation between EDPs and IMs. The results showed that peak ground velocity (PGV)/peak ground acceleration, peak ground displacement and root-mean-square of displacement showed weak correlation with IMs. PGV, sustained maximum velocity, a peak value of spectral velocity, A95 parameter, Housner intensity and spectral acceleration at the fundamental period, the spectral velocity at the fundamental period and spectral displacement at the fundamental period were determined to be better predictors for various EDPs.

Originality/value

This paper investigated the correlation between the intensity measures of intra-plate earthquakes with the seismic responses of a typical long-span cable-stayed bridge in China. The nonlinear finite element model used was calibrated to the existing results of the shaking table test to verify the modeling technique. In total, 104 selected ground motions were applied to the calibrated model, and the responses of various components of the bridge were obtained. This study proposed PGV as the optimal IM.

Abstract

Purpose

Although proximal row carpectomy, wrist arthrodesis and even total wrist arthroplasty were developed to treat wrist disease using bone and cartilage of the wrist, severe and complicated bone defects caused by ferocious trauma and bone tumors remain a stubborn problem for surgeons. Development and application of the three-dimensional (3D) printing technology may provide possible solutions.

Design/methodology/approach

Computed tomography (CT) data of three cases with severe bone defects caused by either trauma or bone tumor were collected and converted into three-dimensional models. Prostheses were designed individually according to the residual anatomical structure of the wrist based on the models. Both the models and prostheses were produced using 3D printing technology. A preoperative design was prepared according to the models and prostheses. Then arthroplasty was performed after preoperative simulation with printed models and prostheses.

Findings

The diameter of the stem and radial medullary cavity, the direction and location of the prosthesis, and other components were checked during the preoperative design and simulation process phases. The three cases with 3D printed wrist all regained reconstruction of normal anatomy and part of the function after surgery. The average increasing Cooney score rate of Cases 2 and 3 was 133.34 ± 23.57 per cent, and that of Case 1 reached 85 per cent. The average declining rate of the Gartland and Werley Score in Cases 2 and 3 was 65.21 ± 18.89 per cent, and that of Case 1 dropped to 5 per cent in the last follow-up. The scores indicated that patients experienced pain relief and function regain. In addition, the degree of patient satisfaction improved.

Originality/value

3D printed wrist arthroplasty may provide an effective method for severe and complicated cases without sacrificing other bones. Personal customization can offer better anatomy and function than arthrodesis or other traditional surgical techniques.

Abstract

Purpose

The purpose of this paper is to examine the state of readiness of large UK based retailing companies for the introduction of ubiquitous computing (U‐computing) retailing applications.

Design/methodology/approach

A questionnaire was distributed to a sampling frame of large British retailers, leading to 255 responses. The document contained items concerning, inter alia, a firm's level of preparedness, managerial attitudes towards and support for U‐computing applications, strategic fit and pre‐existing IT capacities.

Findings

A third of the respondents reported the existence of a “good fit” between U‐computing retail applications and their companies' products, activities and core competencies. However, only 20 per cent of the sample appeared to be well‐prepared for the introduction of U‐computing. There was little evidence of the sample enterprises adopting strategic approaches to implementation.

Research limitations/implications

Only a minority of the firms in the sampling frame participated in the research and the sample size was modest. Data were self‐reported and only a single country was considered. The study concerned just large businesses.

Practical implications

The outcomes suggest a widespread “wait and see” approach towards U‐computing among the sample businesses and a distinct lack of strategic thinking regarding implementation.

Originality/value

This is the first empirical study to explore the prospective introduction to British retailing of a new technology that possesses the potential to revolutionise the operations of UK retailing firms.

Abstract

Purpose

In this chapter, we document the growing importance of FDI from BRIC countries in relation to FDI from both developed and developing countries and investigate the types of firms that are responsible for BRIC FDI.

Methodology/approach

We follow a two-step empirical approach. First, we provide macro evidence on FDI from BRIC countries. We use UNCTAD data to highlight the patterns of FDI flows and stocks. Second, we provide firm-level evidence on FDI. Using ORBIS data, we elaborate a rich taxonomy of FDI that accounts for the decision to invest abroad and for the location, ownership, and number of foreign subsidiaries. Thus, we characterize BRIC multinationals’ involvement in FDI and examine the relationship between FDI and performance at the firm level.

Findings

We unveil new facts about BRIC multinationals. BRIC multinationals are in the minority in their home countries, but they outperform domestic enterprises. Within the group of BRIC investors, those firms that invest in developing countries, that operate in joint ventures, or that have more than five foreign subsidiaries are in the minority, but they outperform those firms that select other FDI strategies.

Research limitations/implications

Our estimates document a positive and robust correlation between FDI and performance; however, the cross-sectional nature of our data does not permit a proper causality analysis.

Originality/value

Our work contributes to the International Economics literature on internationalization and firm performance as well as to the International Business literature on FDI from emerging economies. With respect to the former, we innovate by studying the relation between FDI strategies and firm performance. In relation to the latter, we innovate by introducing firm-level data and a cross-country approach that lets us illustrate the roles and features of FDI from BRIC countries.

Abstract

This chapter examines the limit properties of information criteria (such as AIC, BIC, and HQIC) for distinguishing between the unit-root (UR) model and the various kinds of explosive models. The explosive models include the local-to-unit-root model from the explosive side the mildly explosive (ME) model, and the regular explosive model. Initial conditions with different orders of magnitude are considered. Both the OLS estimator and the indirect inference estimator are studied. It is found that BIC and HQIC, but not AIC, consistently select the UR model when data come from the UR model. When data come from the local-to-unit-root model from the explosive side, both BIC and HQIC select the wrong model with probability approaching 1 while AIC has a positive probability of selecting the right model in the limit. When data come from the regular explosive model or from the ME model in the form of 1 + nα/n with α ∈ (0, 1), all three information criteria consistently select the true model. Indirect inference estimation can increase or decrease the probability for information criteria to select the right model asymptotically relative to OLS, depending on the information criteria and the true model. Simulation results confirm our asymptotic results in finite sample.
