Social capital and career growth
Authors: Kang Dae-seok , Gold Jeff , Kim Jeongeun , Kim Ilsoo 
Published: October 2019

PurposeThe purpose of this paper is to examine the instrumental use of social capital regarding career growth within an organization, focusing on the mediating role of perceived competence mobilization and the moderating role of two situational variables: perceived external prestige and job insecurity climate.Design/methodology/approachRelationships among the constructs are predicted based on relevant literature, and are tested using survey results from 324 employees working in 14 leading corporations in Korea.FindingsResults show that social capital positively influenced, via perceived competence mobilization, each of two career growth dimensions (i.e. the personal efforts to develop a career and the experience of being rewarded by the organization). In contrast, moderated path analysis indicated that perceptions of external prestige and job insecurity climate failed to moderate the indirect effect of social capital on career growth.Practical implicationsIn light of the instrumental use of social capital and the ensuring mechanism of competence mobilization, a detailed understanding of this effect on career growth cannot only neutralize the fears of brain drain, but is also helpful in providing possibilities for building new career development strategies.Originality/valueAlthough social capital has become an influential concept in social sciences, little evidence has been presented on the above relationship, particularly from the perspective of careerist orientation. This may be the first research examining how and when the influence of social capital becomes instrumental with respect to career attainment within an organization.

Purpose
The purpose of this study was to examine the process of the use of management’s positivity and negativity sources and their mediation on pharmaceutical members’ satisfaction that, in turn, enable a health-care organization to meet its business objectives with more agility.

Design/methodology/approach
Data were obtained from a survey of 106 pharmaceutical members regarding their relationships with management.

Findings
The results of LISREL analysis revealed that the use of positivity variables such as reward enhanced each of referent, expert and positive conflict; in addition, referent boosted satisfaction. However, the use of negativity variables such as opportunism enhanced power, but weakened each of referent, expert and legitimate power sources. The use of coercion enhanced power too, but produced dissatisfaction. Further, the prevalence of negative conflict caused dissatisfaction.

Originality/value
This study also reported major contributions when it examined the effect of the mediation of the use of positivity intrinsic power sources on satisfaction. It found that referent power functioned as a full mediator by dropping the amount of the relationship between the use of reward and satisfaction to zero and as a partial mediator by dropping the amount of the relationship between the use of coercion and satisfaction. In addition, the use of referent power mediated the joint effect of both the use of coercion and reward power sources, triggering a positive effect on satisfaction. Several managerial implications were discussed.
Are farmers in Ethiopia ready to embrace cost-sharing agricultural extension approach?
Authors: Wordofa Muluken Gezahegn 
Published: October 2019

Purpose
The purpose of this paper is to investigate perceptions of smallholder farmers toward the cost-sharing agricultural extension service provision.

Design/methodology/approach
The study used data from a cross-sectional survey, key informants interviews and focused group discussions conducted on 384 farm households from six Kebeles of Eastern Ethiopia.

Findings
The authors find that flexibility and credibility, ability of development agents to address neglected aspects in agricultural production, and reaching diversified groups of farmers as the perceived advantages of the cost-sharing approach. Furthermore, improved knowledge and attitude, enhanced research–extension–farmer linkages, and improved food security and poverty reduction are found to be the three most important impact areas associated with the approach. On the contrary, poor economic status of farmers, high cost of administration and absence of a clear guideline/legislation are found to be the most important constraints. The authors find that increasing farmers’ awareness about the cost-sharing approach and preparing a clear definition of the form, modalities and principles of the cost-sharing extension approach can be a part of the practical solutions to overcome the challenges.

Research limitations/implications
The current research is limited to the investigation of farmers’ perceptions toward paid extension services. The willingness to pay for extension services – using discrete choice experiments – is dealt with in another paper.

Originality/value
The first of its kind in the country, the paper tried to assess farmers’ readiness to try a new extension service delivery. The findings have important implications for policy makers and local level implementers of extension programs.
Tourist profiles and attitudes: a comparison between cities in a different phase of the life cycle
Authors: Valls Giménez Josep-Francesc , Pipoli Gina , Rita Paulo , Labairu-Trenchs Itziar 
Published: October 2019

Purpose
The purpose of this paper is to analyse the different typologies of tourists that appear in cities that are in a different position within the destination life cycle. Barcelona and Lisbon, two urban destinations, with a strong growth of tourists in the last two decades, which are in advanced stages of their life cycle, and Lima, which has also expanded in the last ten years, but is in less advanced phases, have been chosen. The approach of the study is to analyse if urban tourists modify their attitude in some way in the face of the advancement of the life cycle of the city and what attitudes are expressed by them.

Design/methodology/approach
For this purpose, an analysis of main components was performed via factor analysis to reduce the number of dimensions of the 11 descriptive variables and the counterpart of tourist attitudes, following Schwartz’s (2006) research. From the four clusters that emerged – authenticity; innovative and cultural hard; relaxation and not innovative – four attitude variables were selected since they were considered relevant to be analysed according to the life cycle of the city: culture and entertainment; authenticity and online social exhibition; and expensive and cheap price.

Findings
The results obtained do not allow to straightforwardly conclude that as the life cycle of these three cities advances, the attitude evolves from culture to entertainment, from authenticity towards online social exhibition or from the most expensive to the cheapest. The tourists from Barcelona are mostly associated with entertainment, those from Lisbon are associated with culture and those from Lima are split. However, in the face of authenticity, travellers are prone to it. Regarding the price, those in Barcelona are almost divided equally, whereas those in Lisbon, and especially those in Lima, consider it to be mostly cheap.

Originality/value
From this study, it can be drawn that the attitude of travellers to these three cities is not conditioned by the life cycle. Globalization and digitalisation put pressure on the traveller by configuring a universal model of behaviour before the urban offer that is associated with other factors, but not with the life cycle of the city.
Cryptocurrencies: applications and investment opportunities
Authors: Inci A. Can , Lagasse Rachel 
Published: October 2019

PurposeThis study investigates the role of cryptocurrencies in enhancing the performance of portfolios constructed from traditional asset classes. Using a long sample period covering not only the large value increases but also the dramatic declines during the beginning of 2018, the purpose of this paper is to provide a more complete analysis of the dynamic nature of cryptocurrencies as individual investment opportunities, and as components of optimal portfolios.Design/methodology/approachThe mean-variance optimization technique of Merton (1990) is applied to develop the risk and return characteristics of the efficient portfolios, along with the optimal weights of the asset class components in the portfolios.FindingsThe authors provide evidence that as a single investment, the best cryptocurrency is Ripple, followed by Bitcoin and Litecoin. Furthermore, cryptocurrencies have a useful role in the optimal portfolio construction and in investments, in addition to their original purposes for which they were created. Bitcoin is the best cryptocurrency enhancing the characteristics of the optimal portfolio. Ripple and Litecoin follow in terms of their usefulness in an optimal portfolio as single cryptocurrencies. Including all these cryptocurrencies in a portfolio generates the best (most optimal) results. Contributions of the cryptocurrencies to the optimal portfolio evolve over time. Therefore, the results and conclusions of this study have no guarantee for continuation in an exact manner in the future. However, the increasing popularity and the unique characteristics of cryptocurrencies will assist their future presence in investment portfolios.Originality/valueThis is one of the first studies that examine the role of popular cryptocurrencies in enhancing a portfolio composed of traditional asset classes. The sample period is the largest that has been used in this strand of the literature, and allows to compare optimal portfolios in early/recent subsamples, and during the pre-/post-cryptocurrency crisis periods.
Stock market liberalization: implications on cost of capital in emerging Islamic countries
Authors: İlhan Bilal 
Published: October 2019

PurposeMost of the major Islamic countries’ stock exchanges have not been able to perform at the same pace with the major emerging countries’ stock exchanges since the mid of 1990s. The purpose of this paper is to examine the implications of stock market liberalization on cost of capital as one of the crucial driver to stock market development and physical investment growth in emerging Islamic countries.Design/methodology/approachThis study employs static panel data techniques on the sample of seven emerging Islamic countries over the years 1989-2008.FindingsThe findings of this study suggest that stock market liberalization significantly reduces cost of capital in the stock markets of sample Islamic countries, which carries policy-oriented implications. Reduction in the cost of capital increases the number of exchange-traded companies, profitability of projects and aggregate investment level; therefore, the study findings are highly concerned by the economic policymakers, corporations and investors alike.Research limitations/implicationsIn the literature, different proxies are employed to measure stock market liberalization and cost of capital as well. Due to data limitations, this study could not employ different proxies for both, especially for stock market liberalization, for robustness purpose. That limitation further restricted the coverage of Islamic stock markets and time period. Therefore, generalization of the study results for overall Islamic stock markets can be slightly drawn.Originality/valueThe paper provides further understanding regarding the effects of SML on cost of capital, thereby indirectly on the stock market development, in the context of EIC.
The dynamic capabilities of AccorHotels in Brazil
Authors: Costa João Henrique de Paiva , Pereira Yákara Vasconcelos 
Published: October 2019

PurposeAccorHotels commenced operations in Brazil in the 1970s. Since then, the company has experienced several economic crises in that country and almost gone bankrupt. Using the dynamic capabilities (DCs) framework, the purpose of this paper is to understand how the company managed to maintain its competitive advantage in such a turbulent and competitive environment over the years. The study sought to identify the main DCs developed in the company between 1974 and 2018 and understand how they were developed based on the analysis of their key microfoundations.Design/methodology/approachThe study adopted a qualitative approach. The data were collected in 22 interviews, including with top management and the founder of the hotel chain in Brazil. The interviews took place in three different years, 2005, 2016 and 2018. The investigation is supported by content analysis of the data.FindingsThe four main DCs identified at AccorHotels were capability to innovate; qualification capability; renewal capability; and capability to manage threats and mitigate risks. In addition to shedding light on the origins of the DCs, the importance of microfoundations is discussed.Research limitations/implicationsThe model presented in the theoretical framework and results should not be generalized, since this limitation is inherent to qualitative research. On the other hand, there are academic implications relevant to the development of the DCs in the service sector by revealing four capabilities that can enable sustainable competitive advantage.Practical implicationsThe results provide business practitioners in the hotel sector with information about DCs and microfoundations to face the external and competitive environment throughout its trajectory. Specifically, it shows the way to develop the capabilities that can collaborate in the exploration of opportunities.Social implicationsExecutives have the responsibility to make appropriate strategic decisions to stay in the market, meeting the expectations of stakeholders. However, the demand is not only financial, employees of tourism businesses are part of family units. Given this context, society gains when studies of this type are developed, because from the socialization of the results obtained from Accor Hotels, leaders can make organizations thrive and foster the professional development of workers, and tourism industry in general.Originality/valueThis is the first study of DCs undertaken with an international hotel chain. In addition, studies on DCs in the tourism industry are still scarce, and Brazil is an environment where hotels have shown steady growth.

Help or harm? The effects of ICTs usage on work–life balance
Authors: Wang Xiaoyan , Gao Liangmou , Lin Zhong 
Published: October 2019

Purpose
Leveraging boundary theory and person–environment fit theory, the purpose of this paper is to propose a model that illustrates the process by which nonwork-related information and communication technologies (ICTs) usage during office hours affects family-to-work conflict (FWC) and work–family balance satisfaction (WFBS), and the moderating effect of family–work segmentation preference (FWSP) in that process.

Design/methodology/approach
Analyses using PROCESS were conducted to analyze the proposed relationships on survey-collected data.

Findings
Augmented ICTs usage led to greater perceptions of FWC, though the strength of this association was contingent on FWSP in that integration preference buffered ICTs usage’s detrimental effects. Moreover, ICTs usage was shown to exert an effect on WFBS through FWC. The results indicated a mediated moderation pattern such that the moderating role of ICTs usage and FWSP on WFBS was mediated by FWC.

Originality/value
By focusing on ICTs usage for family reasons at work, the study filled a formerly acknowledged gap in the research field regarding how nonwork-related ICTs usage at work affected work–life balance.
How to balance your technology sourcing portfolio in a developing country
Authors: Shekarchian Sajjad , Albadvi Amir 
Published: October 2019

PurposeTo gain the highest performance in technological efforts, firms have to balance their technology sourcing portfolio, i.e. they have to decide how to source the required technology and whom to source from. This paper aims to tackle the issue by investigating the factors affecting the technology sourcing portfolio composition and the effect of the portfolio diversity on the performance outcome.Design/methodology/approachAn inductive multiple case study was performed. Data of four biopharmaceutical producer firms in the period of 1998-2017 were collected. To expand the under study time span, the under study firms were all chosen from the first-comer ones. They entered the NBP arena in the 1998-2008 period, i.e. the period in which Iranian NBP industry was in its formation stage.FindingsThis paper detects the affecting technology-, firm-, industry- and national level factors in Iran biopharmaceutical industry and analyses their influencing mechanism. It is demonstrated that there are factors in a developing country, specifically Iran, which do not matter in developed countries. In addition, the synergistic effect of using various technology sources vehicles is confirmed.Social implicationsInaccessibility to infrastructures and global communication barrier problems are features of Iran innovation system. Such features discourage the foreign firms to make long-term investments in Iran which consequently deprives Iranian firms of their knowledge and technology. The modification of these problems is suggested.Originality/valueFactors such as access to infrastructures and global communication barrier are not prevalent in developed countries; therefore, less attention has been paid to them in the literature.
The relationship between governance structure and football club performance in Italy and England
Authors: Ruta Dino , Lorenzon Luca , Sironi Emiliano 
Published: October 2019

PurposeThe purpose of this paper is to verify the theoretical assumption about a weaker role of internal governance structures (namely, board and CEO) in determining sporting and financial performances in highly concentrated club ownership environment.Design/methodology/approachUsing data from the Italian and English football clubs playing in their national top divisions, over the period 2006–2015, the authors apply agency theory, property rights theory and win maximization logic to test the absence of a significant impact of internal governance structures on financial performances and clubs’ sporting performance. Ownership structure’s variables are used as control variable.FindingsEmpirical findings document an overall poor impact of board structure and CEO features on financial performances, in comparison with the influence of ownership structure; the consolidation of win maximization logic of clubs’ owners has been demonstrated in this specific context. However, the authors found that some internal governance elements have also an impact on performance even if their contribute is limited: board size results negatively associated to club profitability, board independence and CEO tenure are positively related to sporting performance; in addition, CEO tenure also increases profitability.Originality/valueThe originality of the paper lies on the contribution arising from this empirical research, since a scarcity of empirical studies analyzing the correlation between internal governance and performance in European football sector is noticed.

Authors: Zhang Xiaoming , Lei Chen , Liu Jun , Li Jie , Tan Jie , Lu Chen , Chao Zheng-Zheng , Wan Yu-Zhang 
Published: October 2019

Purpose
In spite of the vehicle, magnetic field interference can be reduced by some measures and techniques in ammunition design and manufacturing stage, the corruption of the vehicle magnetic field can still reach hundreds to thousands of nanoteslas. Besides, the magnetic field that the ferromagnetic materials generate in response to the strong magnetic field in the vicinity of the body. So, a real-time and accurate vehicle magnetic field calibration method is needed to improve the real-time measurement accuracy of the geomagnetic field for spinning projectiles.

Design/methodology/approach
Unlike the past two-step calibration method, the algorithm uses a linear model to calibrate the magnetic measurement error in real-time. In the method, the elliptical model of magnetometer measurement is established to convert the coefficients of hard and soft iron errors into the parameters of the elliptic equation. Then, the parameters are estimated by recursive least square estimator in real-time. Finally, the initial conditions for the estimator are established using prior knowledge method or static calibration method.

Findings
Studies show the proposed algorithm has remarkable estimation accuracy and robustness and it realizes calibration the magnetic measurement error in real-time. A turntable experiments indicate that the post-calibration residuals approximate the measurement noise of the magnetometer and the roll accuracy is better than 1°. The algorithm is restricted to biaxial magnetometers’ calibration in real-time as expressed in this paper. It, however, should be possible to broaden this method’s applicability to triaxial magnetometers' calibration in real-time.

Originality/value
Unlike the past two-step calibration method, the algorithm uses a linear model to calibrate the magnetic measurement error in real-time and the calculation is small. Besides, it does not take up storage space. The proposed algorithm has remarkable estimation accuracy and robustness and it realizes calibration the magnetic measurement error in real time. The algorithm is restricted to biaxial magnetometers’ calibration in real-time as expressed in this paper. It, however, should be possible to broaden this method’s applicability to triaxial magnetometers’ calibration in real-time.
