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 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.
