To provide a more requirements‐driven workload model for eXtensible Markup Language (XML) benchmark over the electronic data exchange and management in collaborative commerce.

A three‐component workload requirements model is formulated. They are the XML object model, the XML query operation model, and the control model. The object model extended from W3C data model gives a set of more generic data and document model. The query model enhanced from current and common benchmarks gives a more generalized set of standard and open queries against XML data and documents. The control model compiled from TPC and industry standards gives a set of more systematic experimental variables and performance metrics to set up and conduct an XML benchmark.

The long‐standing research issues of domain dependency and application irreproducibility of XML benchmarks are addressed, tackled and offered with a novel and computer‐aided alternative. Precision and cost‐effectiveness through a synthetic, standard, and scalable set of requirements‐driven workload model are presented.

XML constructs, constraints, and controls are investigated both in terms of data and documents. Workload formulation from the requirements analysis is explored. In‐depth schema, query, and control model to provide scalability and portability can be applied is developed.

Enterprise information integration over heterogeneous data sources has to be achieved through XML. Performance measurement and evaluation on XML is vital. With a more generic and generalized design, XML benchmark can become the key to the success of B2Bi interoperability and performance.

An origin of requirements‐driven benchmark modeling over collaborative commerce is presented. A novel extension on W3C XML model is created. A innovative enhancement from current XML benchmarks' query model is developed.

The purpose of this paper is to explore the effects of consumer role (involved vs observing) on consumer responses in the context of online group buying (OGB) service failures.

A scenario simulation method with a 2×3 factorial design was used to investigate the impact of consumer role (i.e. involved consumers and observing consumers) on consumer responses (i.e. perceived quality, negative electronic word-of-mouth (eWOM), and switching intention). The moderating role of seller offering type (i.e. physical products, true services, and pseudo services) on the relationship between the consumer role and responses was also tested.

The differences in perceived quality, negative eWOM, and switching intention between involved consumers and observing consumers were significant. Further, seller offering type moderated the relationship between consumer role and consumer response.

These findings provide several important theoretical and practical implications in regard to OGB service failure and recovery.

This study enriches OGB and service failure literature by a pioneering investigation of how consumer roles respond to OGB service failures and how different seller offering types influence the relationship between consumer role and consumer response. The results will help service providers of OGB benefit from enhancing their service recovery strategies to cope with OGB service failures.

Drawing on organization theory perspectives, this chapter investigates how multinational enterprises (MNEs) based in different home countries influence each other's foreign entry decisions. The proposition that the subsidiaries of multinationals from different countries constitute a reference environment and that this environment provides important information for potential new entrants was tested with panel data on foreign entries from 55 home countries into China from 1979 to 1995. The rate of new entries from a focal home country was found to correlate with the number of foreign subsidiaries already established by firms from other home countries with cultures similar to that of the focal home country. This was interpreted as reflecting transnational learning and competition. Uncertainty derived from home-host-country trade ties and cultural differences was shown to moderate this transnational mimetic learning.

The purpose of this paper is to consider a steady two-dimensional magneto-hydrodynamic (MHD) Falkner-Skan boundary layer flow of an incompressible viscous electrically fluid over a permeable wall in the presence of a magnetic field.

The governing equations of MHD Falkner-Skan flow are transformed into an initial values problem of an ordinary differential equation using the Lie symmetry method which are then solved by He's variational iteration method with He's polynomials.

The approximate solution is compared with the known solution using the diagonal Pad’e approximants and the geometrical behavior for the values of various parameters. The results reveal the reliability and validity of the present work, and this combinational method can be applied to other nonlinear boundary layer flow problems.

In this paper, an approximate analytical solution of the MHD Falkner-Skan flow problem is obtained by combining the Lie symmetry method with the variational iteration method and He's polynomials.

Multiple-input multiple-output (MIMO) combined with multi-user massive MIMO has been a well-known approach for high spectral efficiency in wideband systems, and it was targeted to detect the MIMO signals. The increasing data rates with multiple antennas and multiple users that share the communication channel simultaneously lead to higher capacity requirements and increased complexity. Thus, different detection algorithms were developed for the Massive MIMO.

This paper focuses on the various literature analyzes on various detection algorithms and techniques for MIMO detectors. Here, it reviews several research papers and exhibits the significance of each detection method.

This paper provides the details of the performance analysis of the MIMO detectors and reveals the best value in the case of each performance measure. Finally, it widens the research issues that can be useful for future researchers to be accomplished in MIMO massive detectors

This paper has presented a detailed review of the detection of massive MIMO on different algorithms and techniques. The survey mainly focuses on different types of channels used in MIMO detections, the number of antennas used in transmitting signals from the source to destination, and vice-versa. The performance measures and the best performance of each of the detectors are described.

Using the theoretical frameworks of public diplomacy and public relations, we mapped how the Chinese government has used panda imagery to build its national brand on Twitter and how this ‘panda diplomacy’ has facilitated its para-diplomatic actions. Our findings uncover new attempts by the Chinese government to engage in digital diplomacy. Mobilizing panda imagery on Twitter enhanced friendly relations with foreign political leaders and people and established a friendly and peaceful image of China on Twitter.
