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.

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.

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.

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

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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

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.

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.

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.

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.

Amid the COVID-19 contamination, people are bound to use contactless FinTech payment services. Because of restrictions on physical movement and avoidance of touching physical money, people willingly choose mobile payment, resulting in enormous growth in FinTech payment service industries. Because of this, this study aims to examine the effect of factors affecting Gen X and Millennials users to use FinTech payment services.

The authors used 328 responses collected through convenience sampling of Indian users aged between 26 and 57 years in the Delhi-NCR region who are users of FinTech payment services.

The authors’ findings verified that in India, perceived COVID-19 risk, perceived severity for COVID, individual mobility, subjective norms, perceived ease of use and perceived usefulness have statistically significant impacts on FinTech payment services during the COVID-19 pandemic. Structural equation modelling was used to study the proposed research model. Overall, the model predicted 76.9 % of the variation in intention to use FinTech payment services by the abovesaid variables by Indian users during a pandemic.

This study will provide valuable insight to all FinTech service providers and stakeholders in planning and designing the concerned policy. It will be able to draw the attention of users more.

This research added a valuable theory to the existing technology adoption model (TAM) theory. It demonstrated the utility of the above variables in adopting and using FinTech payment services, which will help service providers to develop future strategies because of the COVID-19 pandemic.
