Abstract

Purpose

This study aims to propose a simple experimental method to distinguish the galvanic corrosion, crevice corrosion and self-corrosion in metal/carbon fiber reinforced polymer (CFRP) joints.

Design/methodology/approach

The corrosion behaviors of four different galvanic couples, whose anodes were Zn-coated DP590 steel and Al 6022, and cathodes were two kinds of CFRP, were investigated in immersion and GMW14872 cyclic conditions.

Findings

The results showed that the galvanic corrosion caused by direct contact between CFRP and metals was more serious than that caused by the jointing bolts. The corrosion damage caused by crevice corrosion was severer than that caused by galvanic corrosion. Self-corrosion was also significant, particularly under the cyclic salt spray condition.

Practical implications

Cyclic salt spray test may more reliably simulate the galvanic corrosion of a joint in industrial service environments, and real corrosion damage may be underestimated by a galvanic current measurement.

Originality/value

A deeper understanding of different corrosion mechanisms involved in CFRP/metal joints under different service conditions in industry has been given.

Abstract

Purpose

The purpose of this paper is to conceptualize and classify sources, manifestations and implications of environmental degradation.

Design/methodology/approach

First, the typological analysis is used to conceptualize environmental degradation and its components. Then, the concepts are disaggregated into some dimensions organized in row-and-column variables and a cross-tabulated matrix is constructed. Finally, different types of environmental degradation are identified, labeled and discussed.

Findings

The study distinguishes between two types of degradation as pollution and deterioration and accordingly identifies ten types (five pairs) of environmental degradation. Furthermore, the paper presents a conceptual framework and offers insights into the dynamic interchange between the causes and effects of environmental degradation.

Originality/value

The originality/value of this study resides in reducing the ambiguities associated with the concept of environmental degradation and offering a multidimensional framework that can be used in empirical research to organize propositions, test hypotheses, analyze data and construct indexes.

Abstract

Purpose

This paper aims to examine the conditions, characteristics and strategies pertaining to the rise of emerging markets’ multinationals (EMNEs).

Design/methodology/approach

The paper relies on both academic and professional resources to offer a holistic understanding of EMNEs by reviewing, analyzing and classifying their underlying conditions, characteristics, internationalization motivations, strategies and competitive advantages.

Findings

The analysis indicates that EMNEs ascended as a result of major socio-economic transformations in the past two decades after the Cold War; follow an accelerated path of expansion; implement flexible and decentralized organizational configurations; enjoy strong political connections; do not internationalize according to the ownership-location-internalization paradigm, rather follow the linkage-leverage-learning pattern; benefit from multiple sources of competitive advantage and adopt five main types of international strategies; are becoming more sophisticated and represent serious threats to their counterparts from advanced economies.

Research limitations/implications

As emerging markets and their multinationals are highly heterogeneous, the findings and suggestions remain context-bound.

Practical implications

The paper synthesizes the EMNEs literature, bridges theory and practice and offers an integrative outline that can be useful for international business managers.

Originality/value

The paper takes an all-inclusive approach and provides insights into multiple societal and organizational facets of EMNEs.

Abstract

Purpose

The target of this research is to develop a mathematical model which combines the Resource-Constrained Multi-Project Scheduling Problem (RCMPSP) and the Multi-Skilled Resource-Constrained Project Scheduling Problem (MSRCPSP). Due to the importance of resource management, the proposed formulation comprises resource leveling considerations as well. The model aims to simultaneously optimize: (1) the total time to accomplish all projects and (2) the total deviation of resource consumptions from the uniform utilization levels.

Design/methodology/approach

The K-Means (KM) and Fuzzy C-Means (FCM) clustering methods have been separately applied to discover the clusters of activities which have the most similar resource demands. The discovered clusters are given to the scheduling process as priori knowledge. Consequently, the execution times of the activities with the most common resource requests will not overlap. The intricacy of the problem led us to incorporate the KM and FCM techniques into a meta-heuristic called the Bi-objective Symbiosis Organisms Search (BSOS) algorithm so that the real-life samples of this problem could be solved. Therefore, two clustering-based algorithms, namely, the BSOS-KM and BSOS-FCM have been developed.

Findings

Comparisons between the BSOS-KM, BSOS-FCM and the BSOS method without any clustering approach show that the clustering techniques could enhance the optimization process. Another hybrid clustering-based methodology called the NSGA-II-SPE has been added to the comparisons to evaluate the developed resource leveling framework.

Practical implications

The practical importance of the model and the clustering-based algorithms have been demonstrated in planning several construction projects, where multiple water supply systems are concurrently constructed.

Originality/value

Reviewing the literature revealed that there was a need for a hybrid formulation that embraces the characteristics of the RCMPSP and MSRCPSP with resource leveling considerations. Moreover, the application of clustering algorithms as resource leveling techniques was not studied sufficiently in the literature.

Abstract

Purpose

The purpose of this paper is to investigate the influence of intellectual capital (IC) on the performance of Malaysian automotive manufacturing firms. It also examines the role of strategic thinking (ST) as a moderating variable in the relationship between IC and performance in these firms.

Design/methodology/approach

This study used a quantitative approach, with an initial sample of 228 firms in Malaysia. Partial least squares structural equation modelling (PLS-SEM) was employed to test the study hypotheses.

Findings

The results of the PLS-SEM analysis are as follows: Human capital (HC) and relational capital (RC) have significant effect on performance, but not structural capital (SC). ST has no moderating effect on the relationship between RC or SC and performance although it does moderate the relationship between performance and HC.

Research limitations/implications

Together with the government, CEOs hold responsibility for ensuring that organizations practice effective ST and IC. With the assistance of government, CEOs should exert every effort to be leaders in this matter. In addition, CEOs of automotive manufacturing firm should reduce their emphasis on classical ways of managing organizations processes.

Practical implications

The findings offer guidance to automotive firms considering how to develop IC and ST to improve performance, especially in Malaysia and Southeast Asia.

Originality/value

This is the first study to examine the moderating effect of ST on the relationship between IC and performance worldwide.

Abstract

Purpose

This study aims to elucidate institutional analysis as an effective approach to investigating and designing the multilevel policymaking system of online social networks (OSN) for achieving a participatory model.

Design/methodology/approach

The institutional mapping approach has been used to analyze Iran’s OSN multilevel policymaking system. A combination of two matrices, including institutions-institutions and institutions-functions, was used to perform the institutional mapping. Two main steps were taken to draw the mentioned matrices. First, a review of related studies in Iran’s OSN policymaking system was conducted and the policy functions mentioned in these studies were identified and categorized using the meta-synthesis. Second, based on analyzing two policy documents of Iran’s OSN, institutions and their interactions were identified and policy functions were allocated to institutions.

Findings

Based on the results, the most important policy functions in the current OSN policymaking system in Iran are support, regulatory, monitoring and evaluation, business environment development, culture building and promotion, organizing licenses and permissions, policymaking and legislation. Also, the results show that there are shortcomings in this system, some of the most important of which are lack of transparency in regulatory, little work in culture building and promotion, neglect of the training of specialized human resources and research and development, slow development of the business environment and neglecting the role of nongovernmental organizations in policymaking.

Originality/value

By examining and analyzing how different institutions operate within a multilevel policymaking system, the policymaking process and its overall effectiveness can be enhanced. This analysis helps identify any inconsistencies, overlaps or conflicts in the roles and policies of these institutions, leading to a better understanding of how a multilevel policymaking system is organized.

Abstract

Purpose

The purpose of this paper is to investigate the potential or actual role of rural libraries in preserving indigenous knowledge (IK) of the rural residents in South Khorasan province.

Design/methodology/approach

The study, based on a qualitative research, was carried out by employing the grounded theory method. Data were collected by semi-structured interviews from the research sample population which included 20 rural males, 10 rural females, 8 librarians and 3 well-informed regional IK specialists. The validity of the research was confirmed by peer evaluation, compounded by detailed thorough explanations and external reviewers’ reaffirmations.

Findings

The rural residents of the South Khorasan villages across the province, after having realized the vitality of carrying out this project, were fully motivated and cooperative to provide indigenous knowledge. On the basis of the results from the rural libraries, due to being the solitary knowledge center in the area, these libraries could actively participate in preserving the knowledge and contribute toward the documentation of the indigenous knowledge. This required motivating librarians and increasing their professional, technical, research and verbal skills. The results of the study indicated that, even if the rural libraries of the South Khorasan province did not participate in documentation, preservation, and promotion of the IK and opt for the present form of non-participation, due to their inherent nature, they could become a focal point and play an indispensable role in achieving the objectives by aiding and leading the process at country level and become a focal point for the new generations of rural inhabitants to enlighten themselves and become fully aware of the value of the ancestral knowledge.

Originality/value

Hitherto, none of the researchers in Iran has covered the role of the libraries in general and rural libraries in particular in preserving the indigenous knowledge.
