A quality management system based‐ISO 9001 focuses on confirming process conformance from the initial development of a product through production, test, installation and servicing. Information management has been a key factor affecting the effective implementation of the standard. The aim of this study is to explore management of information flows in quality assurance in project management. It is hoped to that it will be helpful in pursuing continuous quality improvement in the construction industry.

Based on the characteristics of the construction industry, this study designed an organizational structure with three levels, including firm, sub‐firms and project departments. The paper examined the difficulties for the multi‐level organizational structure in information transferring and feedback.

It is found that there are information asymmetries in quality management from internal and external organizations. Internally, information asymmetry exists between contractor, subcontractors and suppliers; and externally, there is no information sharing mechanism between project departments. Information feedback is more difficult than information transferring in a construction firm.

The construction industry has always been bedeviled with great difficulties in sharing information among its participants. Although many construction firms have claimed to be ISO 9000‐certified, there is still missing an effective channel of information flow for quality management.

The paper proposes reengineering current management strategy for establishing an information network for quality management. This study could help construction firms to effectively manage information flow to achieve continuous quality improvement.

The authors consider a dynamic emission-reduction technology investment decision-making problem for an emission-dependent dyadic supply chain consists of a manufacturer and a retailer under subsidy policy for carbon emission reduction. The consumers are assumed to prefer to low-carbon products and formulate a supply chain optimal control problem.

The authors adopt differential game to analyze investment strategies of cost subsidy coefficient with respect to vertical incentive of a manufacturer and a retailer. A comparison analysis under four different decision-making situations, including decentralized decision-making, centralized decision-making, maximizing social welfare, is obtained.

The results show that the economic benefit and environmental pressure have a win–win performance in centralized decision-making. In four different game models, equilibrium strategies, profits and social welfare show changing diversity and have a consistent development trend as time goes on.

The authors estimate the demand function is a linear function in this paper. According to the consumers’ preference to low-carbon products, consumer’s awareness meets the law of diminishing marginal utility like advertising goodwill accumulation. The carbon-sensitive coefficient might be a quadratic expression, which will complicate the problem and be consistent with reality.

It captures that there is a necessity to strengthen cooperation and exchange of carbon emission technology among the enterprises by simulation of different decision-makings when government granted cost subsidy.

The results provide significant guidelines for the supply chain to make decision-makings of emission-reduction technology investment and relevant government departments to determine emission subsidies costs.

An endogenous subsidies coefficient is produced by the social welfare function. Distinguished from previous study, it also considered the influences of carbon emission trade policy and consumer preference.

This study proposes a framework based on salience theory and shows that focusing on one type of risk (idiosyncratic or systemic) can explain overpricing of securities ex ante, and resales at low prices during crisis periods.

The author consider an overlapping generations (OLG) model where each generation lives for two periods and there is no population growth. Agents (investors) start their lives with an endowment W > 0 and have mean-variance utility. They invest their endowment when young and consume when old. Each period, the young investors optimally choose their portfolio from different risky assets acquired from the old generation, all assumed to be in fixed supply.

The author show that investor salience bias can explain excess volatility of asset prices and the resulting fire-sales in periods of financial turmoil. A change in salience – from one component (idiosyncratic) to the other (systemic) – will generate excess volatility. Interestingly, higher risk aversion generally exacerbates the excess volatility of prices. Moreover, the model predicts that if a big systemic shock hits the financial system, due to salience bias the price of systemic assets falls sharply. This relates to the observed fire-sales of assets during the global financial crisis.

The proposed model and results suggest that there may be a scope for intervention in financial markets during turbulences. In terms of ex ante policies the study suggests that investors and regulator should use better risk assessment technologies.

This is the first study constructing a tractable model based on the argument that investor salience may exacerbate the excess volatility of prices during financial downturns. The author relate salience to two types of risk; idiosyncratic and systemic and assume that investors' risk perception is biased towards the type of risk that is currently salient based on prior beliefs or past data. The author show that the diversification fallacy of the precrisis period, where seemingly safe assets were overpriced, can be explained by agents overweighing idiosyncratic risk and ignoring systemic risk.

The purpose of this paper is to study how the expression “integrated management systems” is interpreted in literature, what it means to have an integrated management system (IMS) and what the results of this are.

A literature review was conducted based on Scopus using the search term “Integrated Management Systems.” In the chosen articles, effects of integration, scope, level and extent of integration and if the approach is inside-out or outside-in, have been analyzed.

Most articles on IMS conclude that integration is beneficial regarding cost saving, operational benefits and improved customer satisfaction. The general approach in the articles, describes an inside-out approach with focus on integrating existing management standards. The scope of integration covers typically management systems for quality, environment and occupational health and safety.

An IMS is found to be a system that integrates existing management standards based on an inside-out approach. This indicates possibilities for both practical improvement and research in exploring how integrated stakeholder needs could be managed, possibly as process-based IMSs.

This paper sheds light on the ambiguous interpretation of the IMS concept.

Although numerous signal modalities are available for emotion recognition, audio and visual modalities are the most common and predominant forms for human beings to express their emotional states in daily communication. Therefore, how to achieve automatic and accurate audiovisual emotion recognition is significantly important for developing engaging and empathetic human–computer interaction environment. However, two major challenges exist in the field of audiovisual emotion recognition: (1) how to effectively capture representations of each single modality and eliminate redundant features and (2) how to efficiently integrate information from these two modalities to generate discriminative representations.

A novel key-frame extraction-based attention fusion network (KE-AFN) is proposed for audiovisual emotion recognition. KE-AFN attempts to integrate key-frame extraction with multimodal interaction and fusion to enhance audiovisual representations and reduce redundant computation, filling the research gaps of existing approaches. Specifically, the local maximum–based content analysis is designed to extract key-frames from videos for the purpose of eliminating data redundancy. Two modules, including “Multi-head Attention-based Intra-modality Interaction Module” and “Multi-head Attention-based Cross-modality Interaction Module”, are proposed to mine and capture intra- and cross-modality interactions for further reducing data redundancy and producing more powerful multimodal representations.

Extensive experiments on two benchmark datasets (i.e. RAVDESS and CMU-MOSEI) demonstrate the effectiveness and rationality of KE-AFN. Specifically, (1) KE-AFN is superior to state-of-the-art baselines for audiovisual emotion recognition. (2) Exploring the supplementary and complementary information of different modalities can provide more emotional clues for better emotion recognition. (3) The proposed key-frame extraction strategy can enhance the performance by more than 2.79 per cent on accuracy. (4) Both exploring intra- and cross-modality interactions and employing attention-based audiovisual fusion can lead to better prediction performance.

The proposed KE-AFN can support the development of engaging and empathetic human–computer interaction environment.

The Chinese Government encourages firms to diffuse their operational-level environmental management (EM) into their organization’s mission and strategy to develop strategic EM to promote sustainable development. The purpose of this paper is to utilize two concepts of institutional theory (isomorphic pressures and decoupling behavior) to assess how different institutional forces arising from Chinese macro-level factors (market pressure, business turbulence, legal voids, carbon policy, structural-level governmental interference and guanxi with government) influence the efficacy of strategic EM.

In partnership with a major consulting firm in China, the authors collect multi-informant survey data from 183 manufacturing firms drawn from a variety of industries for testing the hypotheses posited.

The efficacy of strategic EM in the sampled firms is confirmed by the positive association with environmental performance. The authors also find that the efficacy of strategic EM is weakened by market pressure, business turbulence and legal voids, whereas it is strengthened by structural-level governmental interference. However, carbon policy and guanxi with government do not impact it significantly.

To extend the findings on the environmental importance of strategic EM, future research can develop and validate a management framework to guide the adoption of strategic EM. With regard to the four valid macro-level factors influencing the efficacy of strategic EM, future research can identify the reasons (e.g. conflict with corporate functions) behind them to aid manufacturers to mitigate their negative influence or enhance the positive influence on strategic EM.

China’s Government and its manufacturers (or those sharing a similar institutional environment) can expand the scope of their EM efforts from operational-level EM practices to strategic EM. The findings on the valid macro-level factors have led to practical suggestions for government bodies and manufacturers to improve the efficacy of strategic EM adoption. Overall, the implications help achieve the higher levels of firm-level environmental performance and alleviate the global pollution problem.

A particular value of this work lies in the demonstration of combining institutional theory (organization decoupling, isomorphic pressures) with practical consideration such as guanxi with government in the particular institutional environment of China to help address an important and context-related problem, environmental performance.

Regeneratively cooled thrust chamber is a key component of reusable liquid rocket engines. Subjected to cyclic thermal-mechanical loadings, its failure can seriously affect the service life of engines. QCr0.8 copper alloy is widely used in thrust chamber walls due to its excellent thermal conductivity, and its mechanical and fatigue properties are essential for the evaluation of thrust chamber life. This paper contributes to the understanding of the damage mechanism and material selection of regeneratively cooled thrust chambers for reusable liquid rocket engines.

In this paper, tensile and low-cycle fatigue (LCF) tests were conducted for QCr0.8 alloy, and a Chaboche combined hardening model was established to describe the elastic-plastic behavior of QCr0.8 at different temperatures and strain levels. In addition, an LCF life prediction model was established based on the Manson–Coffin formula. The reliability and accuracy of models were then verified by simulations in ABAQUS. Finally, the service life was evaluated for a regenerative cooling thrust chamber, under the condition of cyclic startup and shutdown.

In this paper, a Chaboche combined hardening model was established to describe the elastoplastic behavior of QCr0.8 alloy at different temperatures and strain levels through LCF experiments. The parameters of the fitted Chaboche model were simulated in ABAQUS, and the simulation results were compared with the experimental results. The results show that the model has high reliability and accuracy in characterizing the viscoplastic behavior of QCr0.8 alloy.

(1)The parameters of a Chaboche combined hardening constitutive model and LCF life equation were optimized by tensile and strain-controlled fatigue tests of QCr0.8 copper alloy. (2) Based on the Manson–Coffin formula, the reliability and accuracy of constitutive model were then verified by simulations in ABAQUS. (3)Thermal-mechanical analysis was carried out for regeneratively cooled thrust chamber wall of a reusable liquid rocket engine, and the service life considering LCF, creep and ratcheting damage was analyzed.

The purpose of this paper is to examine the impact of adopting knowledge management systems (KMSs) on firms’ performance. Although many organizations have adopted the notion of KMS, there is little evidence on the effect of KMS on a firm’s performance, especially in an emerging economy like the Egyptian one. An intensive literature review is conducted not only to synthesize but also to establish the conceptual foundations for the systemic perspective of knowledge management and its potential impact on knowledge management performance in an emerging information and communication technology (ICT) industry. This systemic perspective fits with the evolutionary nature of such an emerging industry in Egypt.

The empirical study of this work is conducted on knowledge-intensive firms operating in the field of ICT. The paper is descriptive in nature where a quantitative research design is adopted to survey senior managers’ perceptions – from both national and multinational enterprises operating in Egypt – on the pay-off maintained from creating an integrative KMS. The primary data are collected from 90 managers holding significant top positions related to the knowledge management area. A linear simple regression test is conducted to discover the initial association between the conceptual model’s key variables.

The results of this work reveal that there is a positive association between each of the six elements that constitute a KMS, namely, knowledge: creation, acquisition, codification, sharing, transfer and measurement, and the perceived knowledge management performance. Besides, there is a significant positive association between the adopted total KMS and perceived knowledge management performance. This study provides strong evidence that KMSs are essential to improve firms’ performance. The results of t-test and analysis of variance assert that the gender, types of business, year of experience and age of respondents have no significant difference to perceived knowledge management performance resulting from KMS.

The findings reflect the fact that informants have to deploy six components that constitute a KMS to realize improvements in knowledge management performance. This work also highlights a number of findings of great value to managers in the ICT sector. Yet, the empirical study does not cover all the issues which are linked to KMS implementation. Issues such as culture, trust and leadership role in building a significant KMS are not examined in this work. Also, the generalizability of the findings to other industries must be considered carefully. Although the findings are statistically significant, the framework developed may be quite specific to the ICT organizations.

This paper enhances managers’ understanding in deploying the notion of KMSs to leverage their corporate performance. It also provides managers in emerging markets with an integrative perspective to fundamental issues that encounter them when they put those KMSs into practice.

This research advances understanding of the application and benefit of KMS in ICT firms in several ways: it provides a better understanding of KMS and practices currently being applied in the Egyptian ICT firms. There had been little or no industry-wide empirical research on this topic to date, it provides a better understanding of knowledge processes in the ICT sector; specifically, the links between knowledge acquisition, creation, codification, sharing, transfer and measurement, and their links to performance, the measurement instruments developed for this research constitute a reliable set of construct measures that provide a basis for future research.

This paper advances the knowledge management subject by synthesizing past studies into an integrative KMS that directs scholars’ attention on how to examine the notion. It is claimed that KMS help those managers improve core business processes, management decisions and, accordingly, firms’ performance. Besides, this study suggests a set of implications for managers in an emerging market that has recently adopted the notion of KMSs. This study also reflects the viewpoints and perceptions of key managers in a strongly evolving knowledge-intensive industry that has an increasing impact on the GDP of an entire nation throughout the past two decades.

The purpose of this study is simulation of of polymer electrolyte membrane fuel cell. Proton-exchange membrane fuel cells are promising power sources for use in power plants and vehicles. These fuel cells provide a high level of energy efficiency at low temperature without any pollution. The convection inside the cell plays a key role in the electrochemical reactions and the performance of the cell. Accordingly, the transport processes in these cells have been investigated thoroughly in previous studies that also carried out functional modeling.

A multi-phase model was used to study the limitations of the reactions and their impact on the performance of the cell. The governing equations (conservation of mass, momentum and particle transport) were solved by computational fluid dynamics (CFD) (ANSYS fluent) using appropriate source terms. The two-phase flow in the fuel cell was simulated three-dimensionally under steady-state conditions. The flow of water inside the cell was also simulated at high-current density.

The simulation results suggested that the porosity of the gas diffusion layer (GDL) is one of the most important design parameters with a significant impact on the current density limitation and, consequently, on the cell performance.

This study was mainly focused on the two-phase analysis of the steady flow in the fuel cell and on investigating the impacts of a two-phase flow on the performance of the cell and also on the flow in the GDL, the membrane and the catalyst layer using the CFD.

Material formulation, structuring and modification are key to increasing the unit volume complexity and density of next generation electronic packaging products. Laser processing is finding an increasing number of applications in the fabrication of these advanced microelectronic devices. The purpose of this paper is to discuss the development of new laser‐processing capabilities involving the synthesis and optimization of materials for tunable device applications.

The paper focuses on the application of laser processing to two specific material areas, namely thin films and nanocomposite films. The examples include BaTiO₃‐based thin films and BaTiO₃ polymer‐based nanocomposites.

A variety of new regular and random 3D surface patterns are highlighted. A frequency‐tripled Nd:YAG laser operating at a wavelength of 355 nm is used for the micromachining study. The micromachining is used to make various patterned surface morphologies. Depending on the laser fluence used, one can form a “wavy,” random 3D structure, or an array of regular 3D patterns. Furthermore, the laser was used to generate free‐standing nano and micro particles from thin film surfaces. In the case of BaTiO₃ polymer‐based nanocomposites, micromachining is used to generate arrays of variable‐thickness capacitors. The resultant thickness of the capacitors depends on the number of laser pulses applied. Micromachining is also used to make long, deep, multiple channels in capacitance layers. When these channels are filled with metal, the spacings between two metallized channels acted as individual vertical capacitors, and parallel connection eventually produce vertical multilayer capacitors. For a given volume of capacitor material, theoretical capacitance calculations are made for variable channel widths and spacings. For comparison, calculations are also made for a “normal” capacitor, that is, a horizontal capacitor having a single pair of electrodes.

This technique can be used to prepare capacitors of various thicknesses from the same capacitance layer, and ultimately can produce variable capacitance density, or a library of capacitors. The process is also capable of making vertical 3D multilayer embedded capacitors from a single capacitance layer. The capacitance benefit of the vertical multilayer capacitors is more pronounced for thicker capacitance layers. The application of a laser processing approach can greatly enhance the utility and optimization of new materials and the devices formed from them.

Laser micromaching technology is developed to fabricate several new structures. It is possible to synthesize nano and micro particles from thin film surfaces. Laser micromachining can produce a variety of random, as well as regular, 3D patterns. As the demand grows for complex multifunctional embedded components for advanced organic packaging, laser micromachining will continue to provide unique opportunities.
