Rebar corrosion behavior of coral aggregate seawater concrete by electrochemical techniques
Authors: Wu Zhangyu , Yu Hongfa , Ma Haiyan , Da Bo , Tan Yongshan 
Published: December 2019

Purpose
Coral aggregate seawater concrete (CASC) is a new type of lightweight aggregate concrete that is becoming widely used in reef engineering. To investigate the corrosion behavior of different kinds of rebar in CASC exposed to simulated seawater for 0-270 d, the electrochemical techniques, including linear polarization resistance (LPR) technique and the electrochemical impedance spectroscopy (EIS), were used in the present work.

Design/methodology/approach
The electrochemical techniques, including LPR technique and the EIS, were used in the present work.

Findings
Based on the time-varying law of linear polarization curves, self-corrosion potential (Ecorr), polarization resistance (Rp), corrosion current density (Icorr), corrosion rate (i), and the characteristics of EIS diagrams for different types of rebar in CASC, it can be found that the anti-corrosion property of them can be ranked as epoxy resin coated steel > 2205 duplex stainless steel (2205S) > 316 L stainless steel (316 L) > organic coated steel > ordinary steel. Additionally, the linear regression equation between Rp and charge transfer resistance (Rct) was established. Finally, the EIS corrosion standard of rebar was established from the LPR corrosion standard, which provides a direct standard for the EIS technique to determine the condition of rebar in CASC.

Originality/value
The linear regression equation between polarization resistance and charge transfer resistance was established. And the EIS corrosion standard of rebar was established from the LPR corrosion standard, which provides a direct standard for the EIS technique to determine the condition of rebar in CASC.
Antecedents of work readjustment of professional returnees: evidence from Vietnam
Authors: Hoang Hung Trong , Ho Nga Thi Thuy 
Published: December 2019

PurposeThe purpose of this paper is to investigate the factors influencing work readjustment of Vietnamese returnees who used to study and/or work in a developed country and are currently working in different positions in their home country.Design/methodology/approachData for this study were collected through a survey of 433 returnees using both paper-based and online surveys. Multiple regression was used to test the relationships in the model.FindingsThe findings show that while the length of time spent overseas, work expectations and subjective norm significantly affect work readjustment, the influences of age, gender and length of time since return on work readjustment are not supported.Practical implicationsThe findings provide useful insights for home country government and managers of returnees developing repatriation programs that help returnees deal with the issue of poor work readjustment.Originality/valueEmpirical studies on cross-cultural re-entry adjustment of both self-initiated repatriates and international students are scarcely investigated. Most prior studies focused on individual factors (such as gender, age, duration in overseas and since return), research on the effect of work expectation on work readjustment is still scant. Most prior studies focused on examining the relationship between work expectation and work readjustment of company repatriates, however, this relationship in the context of returnees, especially in the Asia-Pacific region, has not been investigated. Furthermore, this study is the first to examine the influence of subjective norm on work readjustment of returnees.
The degree of the uncertain reward and customer engagement
Authors: Guo Zhaoyang , Zhang Yuan , Zhang Yirang , Ke Xue 
Published: December 2019

Purpose
As value co-creation has become a critical strategy for companies to gain competitive advantage, the purpose of this paper is to investigate the degree of the uncertain reward (DUR) and its impact on customer engagement (CE), particularly in the promotion stage, which has not been sufficiently explored. Further, optimistic estimation (OE) is examined as an underlying mechanism of the uncertain reward effect, as well as the impact of combining this with other marketing strategies: the controllable lottery and the delayed reward.

Design/methodology/approach
Three studies were conducted to examine the influence of DUR on CE, which included online experiments and a laboratory experiment. In total, 337 participants were recruited from China and the USA to enhance the study’s reliability and validity.

Findings
The research demonstrated that a high-degree uncertain reward led to less OE than a low-degree uncertain reward (LDUR), which subsequently decreased CE (Study 1). However, when other marketing strategies were combined – the controllable lottery (Study 2) and time-delay reward strategy (Study 3) – the uncertain reward effect was reversed (Study 2) or attenuated (Study 3).

Research limitations/implications
The current research only presents two possible reward amounts and independently explores the influence of two popular marketing strategies. Future research can explore customers’ responses to engagement when they face multiple rewards and thoroughly investigate the influence of other social or psychological factors.

Practical implications
Firms could apply an LDUR to enhance CE effects. Furthermore, this could be done at a low cost by empowering customers’ controllability. Nonetheless, firms should be cautious with trade-offs when using time-delay reward strategies.

Social implications
The research contributes to establishing networks of customer–company and interpersonal relationships, as well as fostering closer social ties and social harmony.

Originality/value
This research offers not only initial research on CE in the promotion stage, but also a novel psychological perspective in CE literature. Meanwhile, the study provides substantial value in guiding managers to effectively transform customers into value co-creators.
Ambidextrous innovation orientation effected by the digital transformation
Authors: Scuotto Veronica , Arrigo Elisa , Candelo Elena , Nicotra Melita 
Published: December 2019

PurposeThe purpose of this paper is to introduce a new perspective on ambidextrous innovation orientation looking at how the current digital transformation is accepted in the fashion industry in Italy. Precisely, the objective of the paper is to test whether the use of social media platforms positively influences ambidextrous innovation orientation in fashion companies.Design/methodology/approachEmpirical quantitative research was carried out on a sample of 853 small- to medium-sized enterprises (SMEs) operating in the fashion industry in Italy. Using a logistic regression methodology, four hypotheses were tested to verify the correlation of four dimensions of social media platforms with an ambidextrous innovation orientation among fashion firms.FindingsThe four hypotheses were validated: the structural dimension, the relational behaviour dimension, the cognitive dimension and knowledge transfer practices of social media platforms were proven to positively influence ambidextrous innovation orientation in fashion firms.Research limitations/implicationsThough this is one of the few research studies that offers a quantitative analysis in this field, it could be further developed, for instance by extending the sample of firms to SMEs operating in other countries or by comparing multinationals with SMEs.Originality/valueThis paper provides an original contribution to studies on the use of social media to promote ambidexterity in firms, which has only been studied to a limited extent in the extant literature. From this perspective, the originality of the study is further strengthened by the unique context of analysis, namely, the fashion industry in Italy.

Learning outcomes
Revisar el CAPM como metodología para estimar el costo de los recursos propios en una inversión e ilustrar, mediante un ejemplo latinoamericano, los retos de aplicar el modelo fuera de Estados Unidos. Presentar diferentes alternativas para estimar el riesgo país con una discusión de sus pros y contras. Introducir complejidades adicionales en el estimado del costo de los recursos propios contrastando la perspectiva de un inversionista local no diversificado con el de una multinacional que opera en 39 países

Case overview/synopsis
El caso Hotel Business Inn se enfoca en la estimación del riesgo país para determinar el costo de los recursos propios en una inversión fuera de los Estados Unidos. La teoría financiera indica que este costo debería determinarse en base al riesgo no diversificable de la inversión y para obtener este estimado, los libros de texto recomiendan el CAPM (Capital Asset Pricing Model). Los estimados del CAPM, sin embargo, generalmente se basan en el mercado financiero de Estados Unidos. Para aplicar este modelo en otros países, el consenso es que se debe ajustar por el riesgo país de la inversión pero existe un debate sobre cómo hacer este ajuste. El caso presenta las alternativas más utilizadas e introduce complejidades adicionales en el entorno de un país latinoamericano.

Managing risks in work-integrated learning programmes: a cross-institutional collaboration
Authors: Cameron Craig , Ashwell Janine , Connor Melissa , Duncan Mary , Mackay Will , Naqvi Jeff 
Published: December 2019

Purpose
Work-integrated learning (WIL) poses legal, reputation, operational, strategic and financial risks for higher education providers (HEPs). The purpose of this paper is to explore how HEPs can manage five significant WIL risks involving intellectual property, student disability and medical conditions, the host organisation and the legal literacy of WIL practitioners.

Design/methodology/approach
This paper is a cross-institutional collaboration of WIL practitioners who explored risk management in WIL programmes. The case study is presented as a cross-case analysis to assist WIL stakeholders with evaluating their risk management frameworks. A description about the significance of the risk (in terms of causes and consequences), as well as practices to manage the risk, is presented under each of the five WIL risks.

Findings
WIL practitioners described a series of risk management practices in response to five significant risks in WIL programmes. Four themes underpinning these risk management practices – balance, collaboration, relationship management and resources – are conceptualised as characteristics that can serve as guiding principles for WIL stakeholders in risk management.

Practical implications
The findings can be applied by WIL stakeholders to evaluate and improve existing risk management frameworks, and to improve their legal literacy in relation to WIL. The study also demonstrates the capacity for collaborative research to address practice issues in WIL.

Originality/value
This is the first known study which employs a cross-institutional collaboration of WIL practitioners to contribute towards the body of knowledge examining risk management in WIL programmes.
Sexual harassment and customer-oriented boundary-spanning behaviors
Authors: Jung Hyo Sun , Yoon Hye Hyun 
Published: December 2019

Purpose
The purpose of this study is to evaluate the recognition of sexual harassment (SH); to describe the relationships among SH, employees’ burnout, customer-oriented boundary-spanning behaviors (COBSB); and to verify the moderating effect of employees’ psychological safety (PS), all within deluxe hotels in South Korea.

Design/methodology/approach
Prior to verifying the hypotheses, reliability and confirmatory factor analysis were managed, and correlation analysis was used to confirm the directionality between the hypotheses. The hypotheses were analyzed using a structural equation model and multi-group analysis was used to analyze the moderating effect.

Findings
Perceived SH was significantly related to employees’ burnout and COBSB. Also, the employees’ burnout was significantly related to COBSB. The moderating effect was significant; low PS greatly increased relative to the effects of SH on COBSB.

Originality/value
All types of companies consider unethical behaviors, such as SH in the workplace, as crucial problems that degrade the individual quality of life, and some firms have devised active measures to prevent and relieve damages. Companies should implement employee-centered policies that enable employees, the victims, to formally report and testify to what they have suffered from without revenge from their assailants. All the factors that contribute to the institutional control of SH within the working environment should be taken into consideration, and strict standards should be applied on a company level by criminalizing such behaviors. Employees should be trained on how to effectively cope with diverse types of SH.
The role of innovation and institutions in entrepreneurship and economic growth in two groups of countries
Authors: Galindo-Martín Miguel-Angel , Méndez-Picazo María-Teresa , Castaño-Martínez María-Soledad 
Published: December 2019

PurposeEconomic growth is one the most relevant economic objectives for policy makers. In order to determine the variables that enhance such an objective it is important to consider different types of entrepreneurial activity. It is also necessary to consider the level of development and growth of a country to design the proper economic policy measures, given that entrepreneurship motivations and circumstances vary from country to country. Therefore, the purpose of this paper is to analyse the relationship between entrepreneurship and economic growth, including the role played by institutions and innovation considering two types of entrepreneurship (necessity and opportunity) and countries.Design/methodology/approachData analysis of 31 countries with varying levels of growth and development yielded two large groups – either innovation-driven economies or efficiency-driven economies – following GEM classification based on the phases set out by the World Economic Forum. In order to test the hypotheses, a partial least squares analysis is carried out to show the existing relationships between the different variables, specifically: innovation, institutions, entrepreneurship and economic growth.FindingsThe empirical analysis used demonstrates that innovation positively affects economic growth and entrepreneurship. In addition, adequate functioning of institutions is shown to enhance economic growth and opportunity entrepreneurship. Finally, there is a positive relationship between entrepreneurship and economic growth.Originality/valueUnlike other studies, different types of entrepreneurship (by necessity and opportunity) are essential to this analysis of the relationship between entrepreneurship and economic growth. The country sample was divided considering some country-specific structural circumstances. Neither aspect is considered in the literature and should be considered relevant for designing measures to enhance economic activity.
Entrepreneurship in the digital press: a semantic analysis
Authors: Martí-Sánchez Myriam , Cervantes-Zacarés Desamparados , Ortigosa-Blanch Arturo 
Published: December 2019

Purpose
The purpose of this paper is to analyse how the media addresses entrepreneurship and to identify the attributes linked to this phenomenon.

Design/methodology/approach
The sample is defined in terms of a linguistic corpus comprised of content related to entrepreneurship drawn from the digital editions of the three most important Spanish economic newspapers for the period 2010–2017. Word association and co-occurrence analyses were carried out. Further, a non-supervised clustering process was used as the basis for a thematic analysis.

Findings
Correspondence between social and media patterns related to the entrepreneurship phenomenon is revealed by the results. It is shown how attributes such as “success”, “innovation”, “ecosystem” and “woman” appear as very relevant and are linked to different co-occurrence scenarios. Relevant thematic groups are also identified related to lexical associations such as innovation, digital economy and public policies linked to entrepreneurship.

Research limitations/implications
It is important to emphasise that this study has identified and explored relationships between words, but not their evolution. Furthermore, conclusions cannot be drawn concerning whether there are differences in how each newspaper has dealt with entrepreneurship because of the way the corpus was constructed.

Originality/value
The study provides empirical evidence that helps to identify the way media approaches entrepreneurship. The authors carried out the analysis on the media contents and not on the perception of the public on the phenomenon.
Entrepreneurial self-efficacy and intentions
Authors: Santos Susana C. , Liguori Eric W. 
Published: December 2019

Purpose
Building on social career cognitive theory, the purpose of this paper is to investigate outcome expectations as a mediator and subjective norms as a moderator in the relationship between entrepreneurial self-efficacy and intentions.

Design/methodology/approach
Using a sample of 1,026 students from US public and private universities retrieved from the Entrepreneurship Education Project, this study tests a first-stage moderated mediation model in a two-step process.

Findings
Results show that entrepreneurial self-efficacy is positively related to entrepreneurial intentions through the partial mediating effect of entrepreneurial outcome expectations, and that this relationship is consistently significant and positive for individuals with lower, average and higher subjective norms towards entrepreneurship.

Research limitations/implications
These findings contribute to the literature on entrepreneurial intentions by providing a comprehensive overlook on the mechanisms and boundary conditions relevant for intentions.

Practical implications
These results reinforce the need for educators and policy makers to ensure programs manage outcome expectations and recognize the role of peer, parent and mentor role models on the construction of these expectations and, consequently, on entrepreneurial intentions.

Originality/value
Exploring the combined effect of entrepreneurial outcome expectations as a mechanism and subjective norms as boundary conditions on the relationship between entrepreneurial self-efficacy and entrepreneurial intentions is an unexplored issue to date, and helps to understand how and why entrepreneurial intentions emerge.
