Abstract

Purpose

The purpose of this paper is to develop high-performance Au-coated Ag alloy wires (ACAA wires) and demonstrate the effect of Au coating layers on the bonding performance and oxidation resistance for stable and reliable electronic packaging applications.

Design/methodology/approach

ACAA wire with a diameter of approximately 25 µm and Au layer thickness of approximately 100 nm were prepared by the continuous casting, plating and wire drawing method. The bonding performance of the ACAA wires were studied through bonding on 3,535 chips. The oxidation resistance of ACAA wires and Ag alloy wires (AA wires) were comparatively studied by means of chemical oxidation tests, accelerated life tests and electrochemical tests systematically.

Findings

ACAA wires could form axi-symmetrical spherical free air balls with controllable diameter of 1.5∼2.5 times of the wire diameter after electric flame-off process. The ball shear strength of ACAA wire was higher than that of AA wires. Most importantly, because of the surface Au coating layer, the oxidation resistance of ACAA wires was much enhanced.

Research limitations/implications

ACAA wires with different lengths of heat affected zone were not developed in this study, which limited their application with different loop height requirements.

Practical implications

With higher bonding strength and oxidation resistance, ACAA wires would be a better choice than previous reported AA wire in chip packaging which require high stability and reliability.

Originality/value

This paper provides a kind of novel ACAA wire, which possess the merits of high bonding strength and reliability, and show great potential in electronic packaging applications.

Abstract

Purpose

This paper aims to identify the potential conflicts that arise between the actual and the revealed preference of a panel of wine judges when the panel’s evaluation is derived by a linear aggregation of individual scores.

Design/methodology/approach

A standard axiomatic social choice theoretical model is used to derive and examine the findings.

Findings

The findings show that even with the application of a simple majority rule over the pairwise ranking of wines, preferences may be misrepresented by the ordinal ranking of the wine score aggregation.

Originality/value

A number of wine competitions and reviews, to date, use some form of linear aggregation to represent group preferences. Furthermore, tests surrounding wine judge performance are largely dependent on some underlying true measures usually derived from a linear aggregation. The results imply that care should be taken in these regards.

Abstract

Purpose

The purpose of the chapter is to study the possibility of applying modern intellectual methods and technologies of decision-making for managing complex poorly structured systems.

Methodology

The methodology of the chapter includes fuzzy cognitive approach, analysis of causal connections, dynamic modeling with application of the impulse processes tools, sustainability analysis of the studied system, and scenarios analysis.

Results

The authors offer fuzzy cognitive approach to modeling the risk management system of commercial Bank POS-loaning processes. The simulated system is represented as a fuzzy-oriented weighted multigraph with a pulse action transmitted through it. The modeling process is implemented in the form of successive execution of the following stages: determining the goal, formation of fuzzy cognitive map, dynamic modeling with application of impulse processes tools, and scenarios analysis of development situation and selection the best.

Abstract

Purpose

The goal of this article is to examine the current trends of political cinema in postcolonial Hong Kong. Many leaders of the Hong Kong mainstream cinema have accepted the Chinese authoritarian rule as a precondition for expanding into the ever-expanding Mainland film market, but a handful of conscientious filmmakers choose to make political cinema under the shadow of a wealthy and descendant industry, expressing their desire for democracy and justice and critiquing the unequal power relations between Hong Kong and China.

Design/methodology/approach

This paper consults relevant documentary materials and cinematic texts to contextualize the latest development of political cinema in Hong Kong. It presents an in-depth analysis of the works of two local independent filmmakers Herman Yau and Vincent Chui.

Findings

This study reveals a glimpse of hope in the current films of Herman Yau and Vincent Chui, which suggests that a reconfiguration of local identity and communal relationship may turn around the collective despair caused by the oppressive measures of the Chinese authoritarian state and the end of the Umbrella Movement in late 2014.

Research limitations/implications

Despite the small sample size, this paper highlights the rise of cinematic localism through a closer look at the works of Hong Kong independent filmmakers.

Practical implications

This study reveals an ambivalent mentality in the Hong Kong film industry where critical filmmakers strive to assert their creativity and agency against the externally imposed Chinese hegemonic power.

Originality/value

This investigation is an original scholarly study of film and politics in postcolonial Hong Kong.

Abstract

Purpose

The purpose of this paper is to investigate the relationship between team leader's people value and team effectiveness based on social identity theory. This paper focuses on how team leader's people value affects team effectiveness in the Chinese context. It also examines the mediating effect of leader identification between leader's people value and team effectiveness.

Design/methodology/approach

A literature review on people value, leader identification and team effectiveness provided the authors' model and hypothesis. Using a sample of 64 teams with 386 employees and 64 team leaders from ten companies, hierarchical regression was conducted to test the hypothesis.

Findings

The findings suggest that follower's identification with leader is an important way to understand leader's people value for employees in encouraging employees to strive for team effectiveness. Leaders in teams should pay special attention to their people value for employees.

Research limitations/implications

The data are self‐reported and subject to biases, and may not be accurate, Both the scales of leader identification and team effectiveness were developed in western countries, and they may not capture the full meaning in China. Cross‐sectional data were used in this study; future research should use a longitudinal design to prove the direction of causality among the contracts.

Originality/value

This paper is original in its investigation on how leader's people value influences team effectiveness, through the mediation of leader identification at team level in a Chinese context.

Abstract

Purpose

As the number of available services increases on the web, it becomes greatly vital in service-oriented computing to discover a trustworthy service for a service composition so as to best-fit business requirements. However, some dishonest service providers may advertise more than what they can offer and cause a great loss to users. In the last few years, trust and reputation management over web service selection mechanism becomes an emerging way of dealing with security deficiencies which are inherent in web services environment. The purpose of this paper is to review the security threats carefully and expect that the results serve as a reference guide for designing the robust trust and reputation management mechanisms.

Design/methodology/approach

Based on the published literature, the paper reviews and categorizes the most critical and important security threats that apply to trust and reputation models.

Findings

A detailed review and a dedicated taxonomy table are derived. As emphasized earlier, they could serve as the most important guideline for design of trust and reputation mechanisms.

Originality/value

The papers work contributes to: first, understand in details what kind of security threats may cause damage to trust and reputation management mechanisms for web services selection; and second, categorize these complex security threats and then assist in planning the defense mechanisms.

Abstract

Purpose

To provide the secure web services framework in an environment designed to integrate RFID system into the EPCglobal Network.

Design/methodology/approach

Utilizing web services helps maximize the value of information generated from RFID systems and, taking advantage of web services security (WSS) technology, to provide an XML‐based abstraction layer for established security technologies that delivers confidentiality, integrity, authentication, authorization, and non‐repudiation in EPCglobal Network.

Findings

This paper inspects four cases of trust relationships in one‐to‐one and one‐to‐many teamwork models that exemplify how the proposed WSS specifications being used in industry‐wide EPCglobal Network are envisioned. For each of these cases the different security strategies were proposed. Also a comparative view is given, of discussed security strategies which businesses may wish to consult.

Originality/value

This first proposed secure framework integrating web services and WSS technology to industry‐wide EPCglobal Network will provide business an integration and collaboration capabilities, which make it easier for trading partners to electronically share real‐time RFID data and conduct transactions in an accurate, complete, highly controlled, and secure environment.

Abstract

Purpose

The purpose of this paper is to propose and test an integrated model of mobile advertising taking into consideration the unique characteristics of Asian consumers.

Design/methodology/approach

The survey research method has been used to collect data among young mobile users in China and South Korea. A structural equation model (SEM) technique is employed to analyze the data.

Findings

The results show that Chinese and South Korean consumers share similar beliefs and attitudes toward mobile advertising. Perceived informational usefulness, perceived entertainment usefulness, perceived ease of ease and credibility emerge as significant belief factors positively influencing attitude in both countries. Irritation, on the other hand, negatively predicts attitude. Attitude toward mobile advertising and subjective norm emerge as the strong predictors of consumers’ intention to use mobile advertising in both countries. The effects of perceived social usefulness on attitude and incentive on intention to use demonstrate different patterns between the Chinese and South Korean samples.

Practical implications

The findings are particularly relevant to international marketing managers. To effectively reach Asian consumers through mobile, increasing credibility and entertainment values are the keys. Meanwhile, providing relevant information in easy to use format is also an important issue.

Originality/value

Based on the established advertising theories, this study proposes an integrated model to examine how beliefs, attitude and other influencing factors affect mobile advertising effectiveness among Chinese and South Korean consumers. This research provides insights into the uniqueness and effectiveness of the new mobile medium as opposed to traditional media. Furthermore, this study deepens the understanding of advertising hierarchy effects in an international setting by examining similarities and differences between China and South Korea. Most of existing cross-cultural studies choose cultures that are sharply contrast to gain significant findings and to support established cross-cultural theories. It is also very important for researchers to examine cultures that are relatively similar to gain a better understanding of the impact of culture. The study answers such a call.

Abstract

Purpose

Software module clustering is one of the reverse engineering techniques, which is considered to be an effective technique for presenting software architecture and structural information. The objective of clustering software modules is to achieve minimum coupling among different clusters and create maximum cohesion among the modules of each cluster. Finding the best clustering is considered to be a multi-objective N-P hard optimization-problem, and for solving this problem, different meta-heuristic algorithms have been previously proposed. Achieving higher module lustering quality (MQ), obtaining higher success rate for achieving the best clustering quality and improving convergence speed are the main objectives of this study.

Design/methodology/approach

In this study, a method (Bölen) is proposed for clustering software modules which combines the two algorithms of shuffled frog leaping and genetic algorithm.

Findings

The results of conducted experiments using traditional data sets confirm that the proposed method outperforms the previous methods in terms of convergence speed, module clustering quality and stability of the results.

Originality/value

The study proposes SFLA_GA algorithm for optimizing software module clustering, implementing SFLA algorithm in a discrete form by two operators of the genetic algorithm and achieving the above-mentioned purposes in this study. The aim is to achieve higher performance of the proposed algorithm in comparison with other algorithms.

Abstract

Purpose

The purpose of this paper is to explore the correlations among entrepreneurial environment, market-oriented strategies, and entrepreneurial performance.

Design/methodology/approach

Entrepreneurial environment is measured by institutional environment and industrial environment. A survey of 176 large Chinese automobile firms is conducted. The structural equation model is applied to perform analysis.

Findings

The uncertainty of the institutional environment is positively related with market-oriented strategies and market-oriented strategies are positively related with firms’ performance. The stronger the uncertainty of the industrial environment is, the larger impact that market-oriented strategies have on firms’ performance will be. There is no distinct positive relationship between the uncertainty of industrial environment and firms’ market-oriented strategies. The hypothesis, that the stronger the uncertainty of institutional environments is, the larger the impact that market-oriented strategies will be on firms’ performance, is not supported.

Research limitations/implications

In terms of research design, this paper does not select survey samples randomly. This paper only takes institutional and industrial environments into consideration while the environmental characteristics are omitted.

Originality/value

This paper expands entrepreneurship research by integrating previous studies. Findings in this paper are helpful for firms in emerging countries to implement “going abroad strategies,” to start up new businesses in other countries, and to achieve the goals of improving competitiveness and integrating with international firms.
