Purpose Sulfate-induced degradation is one of the most important factors influencing the durability of concrete. The paper aims to clarify the transport-deterioration process of sulfates in concrete and thus to explain the mechanism and the deterioration of concrete by sulfates. Design/methodology/approach This paper presents an experimental study into the evolution of the transport-deterioration process of sulfate ions in concrete in a pure soaking environment. Findings The microscopic morphology of individual concrete layers at different depths and the change law of the sulfate ion concentration at the corresponding depths were investigated for different exposure times. Furthermore, the relationship between the changes in microstructure and the transport characteristics of the sulfate ions was studied. Originality/value A method to calculate the cracking level sulfate ion concentration was proposed.

Purpose – The purpose of this study is to propose a theory of Islamic consumer behaviour to explain the factors that influence the Islamic mortgage industry. Although previous works have shown that conventional marketing theories were, to a certain extent, able to predict factors influencing halal marketing and Islamic mortgage, these theories fail to capture or accommodate the Islamic perspectives of consumer behaviour. Conventional marketing theories have also been found to be inadequate to explain the Islamic mortgage preference among consumers. Design/methodology/approach – Drawing upon the Maqasid al-Shariah, this study develops an Maqasid al-Shariah index (MSI) and religious satisfaction (RS) for Islamic mortgage industry in Malaysia. These indexes are developed as the basis of the theory development in this setting. The model developed is later examined using survey data. Findings – This study reveals that education and RS are instrumental in determining the Islamic home financing preference. In contrast, justice and welfare are insignificantly related to the Islamic home financing preference. Religious satisfaction, to a certain extent, plays role not only as a mediator but also as a moderator. We find that RS has a full mediation effect on the relationship between welfare and willingness to consider applying Islamic mortgage. We discover justice is moderated by RS. Education and welfare however are not moderated. Originality/value – This study contributes to the development of an empirical Islamic framework in predicting consumers’ behaviour in an Islamic mortgage market using a Maqasid approach. This study is also pioneering in introducing two indexes, notably MSI and RS, and applying these indexes to Islamic home financing context.

Purpose – The purpose of the paper was to examine factors influencing business zakah compliance behavior. Design/methodology/approach – The theory of reasoned action (TRA) was adopted to investigate whether attitude, subjective norm and intention were the determinants of zakah compliance behavior based on questionnaire survey of 227 active businessmen in one district in Malaysia. Findings – Results indicate intention to be a significant predictor for zakah compliance behavior. Intention is further found to be influenced by both attitude and subjective norm, and it mediates the relationship between both factors with business zakah compliance behavior. Practical implications – As attitude, subjective norm and intention are found to influence business zakah compliance behavior, zakah institutions should give serious attention on these factors to improve their zakah collection in the future. Originality/value – The study supports the argument that in a loosely regulated environment like zakah, the TRA can still effectively explain the behavior of zakah compliance.

PurposeThe aim of this paper is to analyze the interrelationship between factors conducive to rural tourism development. This touristic segment has enormous potential but still lacks consistent means and measures to ensure rural tourism's holistic development in India.Design/methodology/approachThe study identified 14 factors, of which nine are from the literature review and five are from interaction with the experts, which influence rural tourism development. The research design comprises three segments, i.e. identifying factors from the literature and expert opinion, conducting interviews with the academic experts and managers, and analyzing the responses recorded. Interpretive structural modeling (ISM) technique is used to determine the interlinkage between the factors and develop a hierarchical relationship.FindingsThe results indicate that infrastructure development, growing environmental conscience, support of local government and community, availability of funds with the government and participation of the private sector are the primary factors channelizing rural tourism development. Also, attitudes of locals to adapt, tourist travel motives, marketing of the destination, destination characteristics and recommendation by others are the major dependent factors identified. The findings broaden the knowledge on suitable channels for rural tourism development and provide vital information for the formulation of flexible strategies for developing rural tourism in India.Originality/valueThis paper's originality lies in providing information to clarify the relationships between factors conducive to rural tourism development, an area where limited research has been done.

Purpose – Activities such as making personal phone calls, surfing on the internet, booking personal appointments or chatting with colleagues may or may not deviate attentions from work. With this in mind, the purpose of this paper is to examine gender differences and motivations behind personal activities employees do at work, as well as individuals’ perception of the time they spend doing these activities. Design/methodology/approach – Data were obtained from 35 individuals (M age=37.06 years; SD=7.80) from a Portuguese information technology company through an ethnographic method including a five-day non-participant direct observation (n=175 observations) and a questionnaire with open-ended questions. Findings – Results revealed that during a five-working-day period of eight hours per day, individuals spent around 58 minutes doing personal activities. During this time, individuals engaged mainly in socializing through conversation, internet use, smoking and taking coffee breaks. Results revealed that employees did not perceive the time they spent on non-work realted activities accurately, as the values of these perceptions were lower than the actual time. Moreover, through HLM, the findings showed that the time spent on conversation and internet use was moderated by the relationship between gender and the leisure vs home-related motivations associated with each personal activity developed at work. Originality/value – This study contributes to the literature on human resource management because it reveals how employees often perceive the time they spend on non-work related activities performed at work inaccurately. This study highlights the importance of including individual motivations when studying gender differences and personal activities performed at work. The current research discusses implications for practitioners and outlines suggestions for future studies.

Purpose The purpose of the paper is to contribute to further advancing of IMP as a research field by setting up and starting a theoretical conversation between system theory and the IMP. Design/methodology/approach The approach is based on a narrative literature study and conceptual research. Findings The authors find that system theory and cybernetics can be regarded as important sources of inspiration for early IMP research. The authors identify three specific theoretical “puzzles” in system theory that may serve as useful topics for discussion between system theorists and IMP researchers. Originality/value Only a handful of papers have touched upon the relationship between system theory and IMP before. This paper combines a narrative, historical analysis of this relationship with developing specific suggestions for using system theory as a vehicle for further advancement of IMP research.

Purpose – The purpose of this paper is to provide insights into the relationship between dynamic capabilities and innovation capabilities. It links dynamic capability with innovation capability and indicates the ways they can be related. Design/methodology/approach – The relationships between dynamic and innovation capability were investigated through a systematic literature review. Findings – The review indicates that common characteristics exist between of the both fields, which demonstrate six relationships. Additionally, findings show some inconsistencies and even contradictions. Originality/value – In this paper, the authors have compared dynamic capabilities, a relatively new approach in the field of strategic management, with innovation capabilities, a widely recognised crucial domain for sustained competitiveness. Since both areas address issues that are essential to today's environment, future research should seek to clarify both concepts, by undertaking some new research and developing comprehensive and unambiguous framework.

Purpose – Dichotomous “gap” thinking about professionals and managers has important limits. The purpose of this paper is to study the specific ontology of “the gap” in which different forms of distances are defined. Design/methodology/approach – In order to deepen the knowledge of the actual day-to-day tasks of Dutch healthcare executives an ethnographic study of the daily work of Dutch healthcare executives and an ontological exploration of the concept “gap” was provided. The study empirically investigates the meaning given to the concept of “distance” in healthcare governance practices. Findings – The study reveals that healthcare executives have to fulfil a dual role of maintaining distance and creating proximity. Coping with different forms of distances seems to be an integral part of their work. They make use of four potential mechanisms to cope with distance in their healthcare organization practices. Originality/value – The relationship between managers and professionals is often defined as a dichotomous gap. The findings in this research suggest a more dynamic picture of the relationship between managers and professionals than is currently present in literature. This study moves “beyond” the gap and investigates processes of distancing in-depth.

Purpose The purpose of this paper is to examine the relationship between Amartya Sen’s notion of adaptation and his views on identity politics by focussing on the issue of slavery and, more specifically, on the example of the happy or contented slave. Design/methodology/approach The paper is text based. The methodological approach adopted is that of conceptual analysis, as is typical for work of this kind. Findings The paper concludes that the example of the happy or contented slave is indeed a fruitful one for those interested in exploring the relationship between Sen’s views on “the adaptation problem” and his views on identity politics, especially in relation to the subjection of women. Here Sen’s debt to the ideas of Mary Wollstonecraft and John Stuart Mill is particularly important. Research limitations/implications One implication of the argument of the paper is that there is a need to consider more carefully the differences that exist between the views of Wollstonecraft and Mill, so far as the example of the happy or contented slave is concerned. Practical implications One practical implication of the paper is that, hopefully, it establishes the continued relevance of the ideas of thinkers such as Wollstonecraft and Mill today, not least because of the influence that they have had on theoreticians such as Amartya Sen. Social implications The paper addresses issues which are of considerable social and political significance, especially for women in underdeveloped societies today. Originality/value The example of the happy or contented slave has not received much discussion in the literature on Sen, although Sen himself has suggested that the distinction between happiness and contentment is an important one, which does merit further discussion.

Purpose – The purpose of this study is to demonstrate the impact of global celebrity chefs and their discourse about food on the genre of cookbooks in Slovenia. Design/methodology/approach – Focusing this discourse study on cookbook topics only, the analysis demonstrates the relationship between the aspirations of local celebrity chefs for the food culture represented globally by global celebrity chefs, such as Oliver, and the necessity for a local construction of specific tastes. While the central genre of TV celebrity chefs remains TV cooking shows, their businesses include a number of side products, such as cookbooks, which can be seen as recontexualisations of TV food discourse. Findings – Hence, despite this study being limited to analysis of cookbooks only, it can be claimed that the findings extend to other genres. The analysis shows that local chefs aspire to follow current trends, such as an emphasis on the local and sustainable production of food as well as enjoyment and pleasure in the form of a postmodern hybrid genre, while, on the other hand, they strive to include topics that will resonate locally, as they aim to represent themselves as the “new middle class”. Originality/value – Such an analysis brings new insights into the relationship between discourse and globalisation as well as discourse and food.

Purpose – The purpose of this paper is to model and test the dynamics of home-regional and global penetration by multi-national enterprises (MNEs). Design/methodology/approach – Drawing on international business (IB) theory, the authors model MNEs adjusting their home-regional and global market presence over time. The authors test the resulting hypotheses using sales data from a sample of 220 of the world’s largest MNEs over the period 1995-2005. The authors focus specifically on the relationship between levels of market penetration inside and outside the home region and rates of change in each domain. Findings – The authors demonstrate that MNEs do penetrate both home-regional and global markets, often simultaneously, and that penetration levels often oscillate within an MNE over time. The authors show firms’ rates of regional and global expansion to be affected by their existing regional and global penetration, as well as their interplay. Finally, the authors identify differences in the steady states at which firms stabilize their penetration levels in the home-regional and the global space. The findings broadly confirm the MNE as an interdependent portfolio with important regional demarcations. Originality/value – The authors identify complex interdependencies between home-regional and global penetration and growth, paving the way for further studies of the impact of regions on MNE expansion.
