Effect of ducts on the hydrodynamic performance of marine propellers
Authors: Liu Yang , Gong Qingwei , Bian Yongning , Suo Qinghui 
Published: July 2021

PurposeHydrodynamic forces and efficiency of bare propeller and ducted propellers with a wide range of advance ratio (J) and attack angle (θ) are examined. The thrust and torque coefficients and the efficiency are presented and discussed in detail. The present results give a reliable guidance to the improvement of the hydrodynamic characteristics of ducted propellers.Design/methodology/approachThe effect of a duct on the hydrodynamic performance of the KP458 propeller is numerically investigated in this study. Finite volume method (FVM)-based simulations are performed for a wide range of advance ratio J (0 ≤ J ≤ 0.75) and attack angle θ of the duct (15° ≤ θ ≤ 45°). A cubic computational domain is employed in this study, and the moving reference frame (MRF) approach is adopted to handle the rotation of the propeller. Turbulence is accounted for with the RNG k-ε model. The present numerical results are first compared against available experimental data and a good agreement is achieved.FindingsThe simulation results demonstrate that the hydrodynamic forces and efficiency increases and decreases with J, respectively, at the same attack angle. In addition, it is demonstrated that the hydrodynamic forces and efficiency are both improved due to the presence of the duct, which eventually leads a better hydrodynamic performance at high advance ratios. It is further revealed that as the attack angle increases, the pressure difference between the suction- and pressure-surfaces of the propeller is also augmented, which results in a larger thrust. The wake field is more uniform at θ = 30°, suggesting that a higher efficiency can be obtained.Originality/valueThe present study aims to investigate the effect of a duct on the KP458 propeller subjected to uniform inbound flow. The relationship between the uniform incoming flow and the attack angle of the duct is mainly focused, and the design of the ducted propellers for any ship hull can be improved according to this relationship.
Change in factor endowment, technological innovation and export: evidence from China’s manufacturing sector
Authors: Rauf Abdul , Ma Ying , Jalil Abdul 
Published: July 2021

PurposeWhile previous studies find innovation to be an essential driver of export growth, the existing literature has neglected the role of different dimensions of technological innovation in export performance, especially in emerging countries. In particular, much less attention has been provided to investigate how enhancing innovation activities in more technical industries influence the relationship between technological innovation and export. Purpose of this paper is to present a unified framework to empirically investigate the integrated impact of the various technological innovation dimensions on export performance of industrial enterprises in China.Design/methodology/approachUsing a panel dataset of enterprise-level data classified into China’s two-digit capital- and technology-intensive manufacturing industries for the 1998–2016 period and applying system-GMM regressions to control for the problem of endogeneity, the authors empirically investigate the integrated impact of a variety of the dimensions of technological innovation on export.FindingsThe authors find that: (1) Domestic R&D efforts and technology spillovers from foreign investment are critical determinants for capital- and technology-intensive exports. (2) External technology may not automatically contribute to export success whereas the interaction of external technology with domestic skill and expertise is a necessary condition for global competitiveness. (3) There exists complementarity between domestic and foreign innovation efforts when they jointly determine export. (4) Chinese government’s trade and innovation policies have significantly contributed to its export growth. Also, the authors examine that the extent of the effect of innovation on export depends upon the type of industry and it is found to be greater in capital- and technology-intensive industries.Originality/valueThis paper fills the research gap in existing literature by distinguishing between different dimensions of technological innovation and integrating them into a unified framework to empirically investigate their impact on export performance of industrial enterprises in emerging countries. The study provides important insights for policymakers.
Health-seeking behaviour and practices among immigrant retail traders in an urban setting in North-Western Ghana
Authors: Yendaw Elijah , Tampah-Naah Anthony Mwinilanaa 
Published: July 2021

Purpose
This study aims to investigate the health-care-seeking behaviour and practices of West African migrants who reside and operate in Wa, Ghana, as itinerant retailers.

Design/methodology/approach
The study was cross-sectional and used the quantitative research approach. The analysis was done on a target population comprising 122 itinerant immigrant retail traders in Wa, Ghana. Fisher’s exact test and logistic regression were used to analyse the data.

Findings
Malaria was the commonest disease among them. Five in ten of the migrants preferred to report malaria episodes to a private health facility than to a government facility. Significant associations were identified between four dimensions (health facility, self-medication, home remedy and consult others) of health-seeking behaviour, and some background characteristics. The main reason why migrants prefer government health facilities was because of their better health personnel. They self-medicated because of easy accessibility of over-the-counter medicine shops. Also, when ill, the migrants usually consulted family members who would be in a position to take them home when their ailment worsens.

Research limitations/implications
Snowball sampling was used to select the respondents which could potentially lead to a sample that is not fully representative of the population in general.

Originality/value
Studies concerning migration and health in Ghana have been focused on internal migrants. Yet, minority immigrant traders equally encounter adverse health conditions but limited studies have been conducted to espouse their health-seeking behaviour. This study imperatively contributes to the subject matter that has limited literature in the country.
Organizational citizenship behavior for the environment: a management perspective
Authors: Akterujjaman Sultan Mohammad , Blaak Liesbeth , Ali Md. Idris , Nijhof Andre 
Published: July 2021

PurposeThis study aims to investigate the relationship between organizational citizenship behavior for the environment (OCBE) of managers and the constructs of the theory of planned behavior: perceived behavioral control (PBC) and attitude toward the environment. The current study also aims to explore the magnitude of this relationship with subjective norms as a moderating variable.Design/methodology/approachData were sourced from a total number of 140 respondents (managers) from different firms in The Netherlands through an online questionnaire by using a mixture of structured, semi-structured and open-ended questions. Having used the correlation test, the study first conducts the exploratory factor analysis and then the reliability test. Finally, it estimates the coefficients by applying the hierarchical regression model to find the relationship between dependent and explanatory variables.FindingsDiagnostic test results revealed that data are highly reliable. The coefficient results indicate that PBC and environmental attitude have positive and significant relationships with OCBE. Additionally, subjective norms have a significant and positive effect on strengthening the relationship between PBC and OCBE; however, it has no impact on the relationship between environmental attitude and OCBE.Research limitations/implicationsThis study has some caveats. First, the results presented in the research are derived from a single moment in time. The second limitation has to do with the insignificant results for the construct of environmental attitude. Third, this study comprises a data set obtained from different companies in The Netherlands.Practical implicationsOrganizations that want to increase their environmental performance could look at the PBC, environmental attitude and subjective norms of the managers in regard to OCBE.Originality/valueThe results of the study contribute to the understanding of the way PBC, environmental attitude and subjective norms positively affect OCBE. Future research should investigate organizational citizenship within business firms by considering corporate social responsibility as a key variable.
Inside the multi-tier supply firm: exploring responses to institutional pressures and challenges for sustainable supply management
Authors: Nath Shobod Deba , Eweje Gabriel 
Published: July 2021

PurposeThe purpose of this study is to examine how multi-tier suppliers respond to the institutional pressures for the implementation of sustainable supply management (SSM) practices in supply chains, and what institutional logics allow them to do so.Design/methodology/approachThis study employs a qualitative research design, drawing on data from semi-structured interviews with 46 owners and managers of multi-tier suppliers and 18 key informants of diverse stakeholders. Following an abductive approach, institutional theory conceptually guides the analytical iteration processes between theory and interview data.FindingsThe findings demonstrate two kinds of thematic responses to institutional pressures – coupling (good side) and decoupling (dark side) of the supply chain – used by the factory management of multi-tier suppliers. This paper also identifies multiple institutional logics – market-led logic, values-led logic and holistic sustainability logic – that are perceived to conflict (trade-offs) and complement (synergies) the SSM implementation.Research limitations/implicationsBy investigating the perspectives of the factory management of upstream apparel suppliers, this study enhances the understanding of the connection between (de)coupling responses and institutional logics inside the multi-tier supplier firms. Further research would be required to include more downstream tiers including the ultimate users.Practical implicationsThe findings may be of particular attention to brand-owning apparel retailers, industry leaders and policymakers who are seeking to understand multi-tier suppliers' challenges, conflicts and (de)coupling responses, and become aware of how they can be dealt with.Originality/valueThis study contributes to and expands the embryonic research stream of sustainable multi-tier supply chain management by connecting it to the wider application of institutional theory.
Bladder and bowel symptoms following imprisonment in West Australian female prisons
Authors: Rice Amee , Thompson Judith Anne , Briffa Kathy 
Published: July 2021

Purpose
The purpose of this paper is to investigate the presence of bladder and bowel symptoms in women recently imprisoned in Western Australian prisons, specifically; stress, urge and mixed urinary incontinence, faecal incontinence, nocturia, nocturnal enuresis and constipation and the impact on the quality of life (QOL).

Design/methodology/approach
Over a 12-month period 29 women, recently released from Western Australia’s female prisons, were surveyed using a questionnaire previously validated for the prison population. The Short Form King’s Health Questionnaire and a modified version of the Manchester Health Questionnaire were used to assess the effects of these symptoms on QOL.

Findings
Of those surveyed only one respondent reported having no bladder or bowel symptoms following release from prison. Trends assessed by Chi-square analysis suggest women imprisoned for any period of time are more likely to develop both bladder and bowel symptoms which persist after release back into the community. A history of substance or alcohol abuse is often concurrent with the presence of symptoms. QOL scores are also lower for those reporting either bladder or bowel symptoms affecting total scores and the domains of both activities of daily living and mental health.

Originality/value
Women imprisoned for any length of time developed bladder and bowel symptoms which had a negative impact on their QOL. Larger studies need to be conducted to investigate these trends and whether small changes in conservative measures can influence outcomes.
Managing design for innovative new products and services
Authors: Nakata Cheryl , Bahadir S. Cem 
Published: July 2021

Purpose
The purpose of this study is to determine how design should be managed to develop truly innovative products and services. Three management levers were examined: design leadership, design inclusion and design thinking.

Design/methodology/approach
The study was carried out as a survey of innovation managers in the USA. The survey measures were developed from the design and innovation literature. Over 300 managers participated in the survey, and their responses were analyzed by using multiple regressions and other statistical tools.

Findings
All three aspects of design that were studied – leadership, team inclusion and thinking – were found to significantly and positively impact new product and service innovativeness. Of these factors, the most important contributor to innovativeness was design thinking, with having more than three times the impact of the other two. Also, firms that are large, publicly held and technology-intensive are on average more innovative.

Practical implications
To increase the innovativeness – or novelty, interest in and influential – of new products and services, managers should appoint designers as leaders on innovation project, include designers in development teams and above all integrate the design thinking process in organizations.

Originality/value
This study determines that design leadership, inclusion and thinking increases the innovativeness of new products and services.
Factors identifying musician entrepreneurship in a less-developed country: a case of Indonesia's independent musician
Authors: Hermawan Marko S. , Abiyusuf Bastian 
Published: July 2021

Purpose
This paper aims to examine Indonesian independent musicians' (indie) adaptation to the environmental business model. The research on institutional entrepreneurship (IE) has been used in organizational studies, including the music profession. However, the music industry's information and technology advancement has not been scrutinized in a less developed country (LDC) context.

Design/methodology/approach
A qualitative approach is used to conduct semi-structured interviews with 14 independent music professionals and enthusiasts. The interview result was three stages of coding, including open, axial and selective, as well as generating appropriate themes.

Findings
The results summarize entrepreneurial behavior, socio-economy and technology factors. The existing literature supports these results, though new perspectives are only identified in the LDC context. Internal factors drive IE, while socio-economy, including music literacy, education and legal issues, influence its sub-setting. On the other hand, technology positively or negatively impacts IE based on individual utilization.

Research limitations/implications
Despite the massive piracy and copyright issues, independent musicians require creativity and innovation beyond product creation. Weak and unclear regulations in Indonesia prevent musicians from revealing their identity and publishing their artwork, preventing or obstructing them from their goals.

Practical implications
This paper illustrates the urgency to implement copyright regulations for musicians in Indonesia, which are insufficiently enforced by law enforcement. Such conditions prevents musicians from revealing their identity and publishing their artwork.

Social implications
This paper addresses the extent to which a community such as independent musician, struggles to find its identity toward the changing of its business model. By mapping the factors associated with an independent musician, the paper suggests that this community has strategic economic potential as a creative entity.

Originality/value
This paper examines the music industry in less-developed nations by contextualizing their institutions using the IE framework. It contributes to identifying the environmental factors influencing independent institutional musicians. Internal and external factors significantly contribute to identifying Indonesia's independent musician setting through IE.
Appraising the role of age among senior entrepreneurial intentions. European analysis based on HDI
Authors: Linardi Marcelo Augusto , Costa Joana 
Published: July 2021

Purpose
The research aims to examine the underlying factors of entrepreneurial intentions among seniors. In this vein, it evaluates the role of social context proxied by the human development index (HDI) along with individual characteristics towards these initiatives. Emerging economies deliver great potential for income generation swiftly approaching the standards of their developed counterparts. Their present ageing trends severely threaten growth prospects because of workforce withering. European insights will help anticipating constraints through alternative models of human capital allocation.

Design/methodology/approach
Four logistic regressions were run to address hypotheses in test, relying upon the global entrepreneurship monitor – adult population survey. Estimations include 20,386 individuals from database and 21 European Union countries. Ex-post robustness checks corroborate the global significance of the proposed model.

Findings
Empirical findings reinforce the importance of the macroeconomic context among senior endeavours and the non-linearities in terms of the age effect. Moreover, context can help eroding gender gaps in this field and refine the opportunity perception These results go in line with the literature and extend the importance of promoting a favourable ecosystem. Promotion of senior endeavours must consider smart policy packages encompassing the individual singularities as this age range will be too important to be wasted. Senior entrepreneurs are key to the latent job market crisis, needing to be encouraged through positive discrimination.

Research limitations/implications
Originally, by incorporating an exogenous variable encompassing the role of the entrepreneurial context, this study contributes academically to evaluating the determinants of entrepreneurial activity among the elderly. In addition, the development of cohorts highlights the specific importance of individual characteristics in entrepreneurial propensity in each context. The heterogenous results proves the ineffectiveness of “one sizes fits all” policies.

Practical implications
This research reinforces extant literature, notwithstanding the empirical refinements implemented brought up two additional perspectives: complementing previous towards the relevance of HDI cohorts along with the non-linearities of the effect of age. Learning from the European context and acknowledging efficacy of policy instruments will avoid serendipitous actions or failures, enhancing promising ecosystems such as emerging economies.

Originality/value
The study academically contributes to the appraisal of the determinants of entrepreneurial activity among seniors, thus, in an original way, by incorporating an exogenous variable to appraise the role of the context. Development cohorts evidence the existence of singularities in entrepreneurial propensity and individual characteristics according to their levels, such that policy actions should consider their differences.
Research on green innovation countermeasures of supporting the circular economy to green finance under big data
Authors: Yaoteng Zhao , Xin Li 
Published: July 2021

PurposeThe purpose of this paper is to explore the sustainable development strategy of green finance under the background of big data.Design/methodology/approachFrom the perspective of big data, this paper uses quantitative and qualitative analysis methods to judge the correlation among green finance, environmental supervision and financial supervision. Green finance gives the entropy method to calculate the score of green finance and environmental regulation, and establishes the spatial lag model under the double fixed effects of time and space.FindingsSpatial autocorrelation test shows that economic spatial weight matrix has obvious spatial effect on green innovation. Through the model selection test, the space lag model with fixed time and space is selected. The regression coefficients of green finance, environmental regulation and their interaction are 0.1598, 0.0541 and 0.1763, respectively, which significantly promote green innovation. The regression coefficients of openness, higher education level and per capita GDP are 0.0361, 0.0819 and 0.0686, respectively, which can significantly promote green innovation.Originality/valueIn view of the current situation of large-scale application of big data technology in green innovation of domestic energy-saving and environmental protection enterprises, this paper establishes a fixed time lag evaluation model of green innovation. M-test statistics show that the original hypothesis with no obvious spatial effect is rejected.

Authors: Sani Achmad , Ekowati Vivin Maharani 
Published: July 2021

Purpose
This study aims to determine the direct and indirect effects of Islamic spirituality on organizational citizenship behavior (OCB) Islamic perspective (OCBIP), identifying the role of spiritual and marketing strategy at work and organizational commitment to mediate the effect of Islamic spirituality on OCBIP.

Design/methodology/approach
The research population is all employees of Sidoarjo BRI Syari'ah Branch Office. Total sample involves 130 fulltime employees. Proportional random sampling technique is a selected technique. Data is collected directly from respondents. The analysis used in this study uses Partial Least Square.

Findings
The research results show that Islamic spirituality has no direct effect on OCBIP. Spiritual at work mediates the effect of Islamic spirituality on OCBIP; organizational commitment mediates the effect of Islamic spirituality on OCBIP.

Originality/value
The OCBIP variable is used as the originality in this study. Another finding in this research is the marketing strategy of sharia-based companies. There has not been a comprehensive examination of the influence of Islamic spirituality and marketing strategies on OCB with spirituality at work and organizational commitment as a mediating variable. This Islamic perspective is very important considering the majority of Indonesian citizens are Muslims.
