Leaders that bind: the role of network position and network density in opinion leaders' responsiveness to social influence
Authors: Zhang Honghong , Gong Xiushuang 
Published: February 2021

PurposeThe purpose of this present study is to investigate how opinion leaders' responsiveness to social influence varies with network positions (i.e. degree centrality and brokerage) and network density in new product diffusion networks.Design/methodology/approachThis study collected data based on a sociometric network survey. Hierarchical moderated regression and hierarchical linear modeling analyses were used to test the moderating effects of degree centrality, brokerage and density on the relationship between opinion leadership and susceptibility to social influence.FindingsThis study documents the significant moderating roles of network positions and network density in the relationship between individual influence (i.e. opinion leadership) and susceptibility to social influence. Interestingly, this study shows that the significant moderating effects of degree centrality and brokerage hold for opinion leaders' responsiveness to informational social influence, whereas that of network density holds for opinion leaders' responsiveness to normative social influence.Research limitations/implicationsThis research sheds light on the network structural characteristics under which opinion leaders would be differentially responsive to social influence (i.e. informational and normative influence) from others.Practical implicationsThis research provides marketing managers with insights into leveraging social influence by activating opinion leaders through existing network ties in new product diffusion networks.Originality/valueAlthough opinion leaders are generally less susceptible to social influence from others than nonleaders, this research finds that, under certain network conditions, opinion leaders would be equally responsive to social influence from their peers.

The sophisticated tools include co-citation and dynamic co-citation network analysis.
The impact of board gender diversity and foreign institutional investors on firm innovation: evidence from China
Authors: Ain Qurat Ul , Yuan Xianghui , Javaid Hafiz Mustansar 
Published: February 2021

PurposeThis study investigates the impact of board gender diversity and foreign ownership on innovation in Chinese firms.Design/methodology/approachThe authors use data for Chinese manufacturing firms listed on the Shanghai and Shenzhen stock exchanges, for a sample over the period 2008–2017. Ordinary least square (OLS) is used as the baseline methodology, with cluster OLS, two-stage Heckman test, Blau index and Shannon index used to address endogeneity issues.FindingsThe results show that gender diversity on the board has a positive effect on corporate innovation as measured by the total number of patent applications, invention patent applications, utility model patent applications and design patent applications. Our findings also provide support for the critical mass participation of female directors on the board being associated with more innovation. They also reveal that innovation output does not vary across state-owned enterprises (SOEs) and non-SOEs. These outcomes reveal that SOEs' advantages, such as easy access to funding and more support of government, are likely offset by their disadvantages, such as different goals and having more agency issues. Because of intense political power and networks in Chinese firms, qualified foreign institutional investors (QFIIs) are less motivated to enhance innovation activities.Practical implicationsThis study highlights the role of board gender diversity in enhancing innovation among Chinese manufacturing firms. Our findings provide support for regulatory bodies' role regarding women's participation on the board.Originality/valueThis research adds to literature by addressing the largely ignored questions of whether providing a gender-diverse board enhances innovation, whether critical mass participation has a greater effect on improving firm innovation and whether the influence of women directors varies with ownership structure.
The adoption of inbound open innovation practices in developing countries: empirical evidence from the manufacturing sector
Authors: Pilav-Velic Amila , Jahic Hatidza 
Published: February 2021

PurposeLiterature suggests that open innovation approach of large firms shows different characteristics with small- and medium-sized enterprises (SMEs), so this paper tends to shed light on these structural differences. With the aim to gain a deeper understanding of the adoption of inbound innovation practices among firms in one small transition economy, this study is focused on the question of how different dimensions of inbound innovation practices affect the innovative performances of SMEs and large firms and how, eventually, these practices should be framed and managed differently.Design/methodology/approachThis paper develops a research model which analyses inbound innovation practices on a data set of 227 SMEs and large firms operating in Bosnia and Herzegovina. The data were collected by using a questionnaire specifically designed for this research. Association between the level of innovation of products in firms and inbound practices, between exploit and explore strategies, between types of industry and different types of collaborations with partners outside the firm is assessed by canonical correlation.FindingsThe research results revealed that inbound innovation practices of manufacturing firms in different stages of innovation development process starting from idea generation, experimentation, up to the commercialization, have positive influence on their innovative performances.Originality/valueThis study contributes to the existing research on open innovation by providing empirical evidences for different dimensions of inbound innovation practices in SMEs and large firms. We offer a very important insight into open innovation practices and challenges beyond well-researched developed countries.
Teachers' psychological well-being role of emotional intelligence and resilient character traits in determining the psychological well-being of Indian school teachers
Authors: Kamboj Kannu Priya , Garg Pooja 
Published: February 2021

PurposeThe substance of the present study lies in analysing the extent to which intrinsic factors like emotional intelligence and resilient character traits impact the psychological well-being of school teachers. It prominences the mediating role of resilient character traits in the relationship between emotional intelligence and psychological well-being of teachers.Design/methodology/approachThis cross-sectional survey study recruits a sample of 200 school teachers across the state of Haryana, India, with the help of a convenience sampling technique.FindingsThe findings from parallel multiple mediation indicate perseverance as a significant mediator and predictor of psychological well-being among factors of resilient traits, and self-reliance emerges as an inconsistent, yet significant mediator in the relationship between emotional intelligence and well-being of teachers. The direct effect of emotional intelligence on psychological well-being also emerged as statistically significant. Additionally, the female school teachers show higher emotional intelligence and resilience as compared to the male school teachers.Practical implicationsThe research is not an unmitigated work in the exploration of a causal relationship between the study variables. However, the study draws practical suggestions for improving the perseverant and emotionally intelligent behaviour of teachers for better emotional and psychological adjustment at work. It acknowledges the role of school administration and education policymakers in furthering the betterment of teachers' psychological state for improved performance and effectiveness. Also, teamwork, stress reduction and leadership building appeared to be helpful contributors to enhance the perseverance and emotional intelligence among teachers.Originality/valueStudies in the field of school administration rarely address the psychological well-being of school teachers as their concern. This study accentuates the impact of intrinsic antecedents of psychological well-being, which is neither well conceptualised in Indian studies nor is causally related to any psychological constructs. Therefore, it remarkably contributes to the literature in the field of educational management and leadership, providing an insight into the psyche of teachers from “the Orient”.
How can mixed integer linear programming assist dairy manufacturers by integrating supply decisions and production planning?
Authors: Emidio Juliana , Lima Rafael , Leal Camila , Madrona Grasiele 
Published: February 2021

PurposeThe dairy industry needs to make important decisions regarding its supply chain. In a context with many available suppliers, deciding which of them will be part of the supply chain and deciding when to buy raw milk is key to the supply chain performance. This study aims to propose a mathematical model to support milk supply decisions. In addition to determining which producers should be chosen as suppliers, the model decides on a milk pickup schedule over a planning horizon. The model addresses production decisions, inventory, setup and the use of by-products generated in the raw milk processing.Design/methodology/approachThe model was formulated using mixed integer linear programming, tested with randomly generated instances of various sizes and solved using the Gurobi Solver. Instances were generated using parameters obtained from a company that manufactures dairy products to test the model in a more realistic scenario.FindingsThe results show that the proposed model can be solved with real-world sized instances in short computational times and yielding high quality results. Hence, companies can adopt this model to reduce transportation, production and inventory costs by supporting decision making throughout their supply chains.Originality/valueThe novelty of the proposed model stems from the ability to integrate milk pickup and production planning of dairy products, thus being more comprehensive than the models currently available in the literature. Additionally, the model also considers by-products, which can be used as inputs for other products.
Linguistic tone of management discussion and analysis disclosures and the municipal debt market
Authors: Rich Kevin T. , Roberts Brent L. , Zhang Jean X. 
Published: February 2021

PurposeAs the management discussion and analysis (MD&A) section contains discretionary narrative disclosures regarding a government's yearly financial changes and status, the authors investigate several municipal debt market consequences of linguistic tone within these disclosures.Design/methodology/approachThe authors textually analyze municipal MD&As with Linguistic Inquiry and Word Count (LIWC) software and develop narrative tone measures based on existing financial-specific dictionaries. Using a final sample of 446 municipal bond issuances from 2012 to 2016, the authors modify the current bond regression models to examine the association between MD&A disclosure tone and future bond interest costs or rating disagreements.FindingsThis study’s empirical analysis suggests that more negative MD&A tone is associated with higher future debt costs and greater future disagreements among bond rating agencies.Practical implicationsOverall, the evidence implies that municipal bond stakeholders use the information in narrative disclosures when evaluating risk, but that the qualitative nature can introduce differences in interpretation between users. Furthermore, additional training in MD&A writing and further standard guidance in MD&A disclosures could improve the MD&A's informativeness for bond market decision-making and state-level monitoring.Originality/valueThis study is first to incorporate narrative tone measures into bond models in a governmental context.

SummaryConcurrent osmotic and chaotropic stress make MgCl2‐rich brines extremely inhospitable environments. Understanding the limits of life in these brines is essential to the search for extraterrestrial life on contemporary and relict ocean worlds, like Mars, which could host similar environments. We sequenced environmental 16S rRNA genes and quantified microbial activity across a broad range of salinity and chaotropicity at a Mars‐analogue salt harvesting facility in Southern California, where seawater is evaporated in a series of ponds ranging from kosmotropic NaCl brines to highly chaotropic MgCl2 brines. Within NaCl brines, we observed a proliferation of specialized halophilic Euryarchaeota, which corresponded closely with the dominant taxa found in salterns around the world. These communities were characterized by very slow growth rates and high biomass accumulation. As salinity and chaotropicity increased, we found that the MgCl2‐rich brines eventually exceeded the limits of microbial activity. We found evidence that exogenous genetic material is preserved in these chaotropic brines, producing an unexpected increase in diversity in the presumably sterile MgCl2‐saturated brines. Because of their high potential for biomarker preservation, chaotropic brines could therefore serve as repositories of genetic biomarkers from nearby environments (both on Earth and beyond) making them prime targets for future life‐detection missions.
Regulating the post‐employment of public officials: Australian experience in an international context
Authors: Mulgan Richard 
Published: February 2021

AbstractThe potential abuse of power by public officials after they have left government employment became a major issue in Australia with the appointment of two recently retired senior federal ministers to lucrative positions with firms which had close dealings with their former departments. The cases raise important questions about the regulation of ‘the revolving door’ which is an increasing feature of governance as the public and private sectors move more closely together. Australian Commonwealth rules relating to both ministers and public servants are analysed in the context of international practice and as part of the wider issue of conflict of interest. Four types of conflict are relevant to post‐employment: ingratiation, profiteering, influence, and switching sides. The regulation of each type is discussed and Australian practice seen to be deficient in certain respects, particularly in relation to ministers. Regulation in this area faces two general challenges: definition of the offence and the comparative absence of oversight and sanctions. But international exemplars offer prospects for strengthening Australia's ethical regime.
The female payer: Gender differences in characteristics among child support payers
Authors: Claessens Elke , Mortelmans Dimitri 
Published: February 2021

AbstractNonresident mothers who formally pay child support are becoming increasingly prevalent. If the profile of female payers differs from that of men or if their payment is motivated differently, existing gender‐based child support policies and enforcement strategies face significant challenges. This study uses the payment framework of male compliance to map the differences between male and female payers of child support. The analysis applies discriminant analysis to a combination of register and fiscal data of separated parents. Whereas the separate aspects of the payment framework did not reach the threshold for acceptable discrimination, the full model revealed considerable differences between male and female payers. The aspect of willingness to pay showed the greatest discriminating power, suggesting that paying mothers have a higher willingness to do so than fathers. We conclude that while the discrepancies between nonresident mothers and fathers who pay child support can be partly attributed to demographic differences and residency patterns of children, differing motivations are also of importance.

Authors: Benchikh Yassine , Sahli Sana , Alleg Moussa , Mohellebi Nassima , Gagaoua Mohammed 
Published: February 2021

This study aimed to optimise the extraction parameters of anthocyanins from Arbutus unedo L. fruits and then perform a new formulation of yoghurt using the extracts as a supplement. Thus, the Box–Behnken model was applied to investigate the effects of agitation speed (600–1000 rotations per minute (rpm)), sample/solvent ratio (1–6 mg/mL) and extraction time (5–25 min) on total anthocyanin content (TAC) and antioxidant activity. The optimal conditions were 770 rpm, 3.59 mg/mL and 15.61 min. The enriched yoghurt with the anthocyanins contained 32.57 µg cyanidin‐3‐glucoside equivalent/100 g of TAC. The new formulated yoghurt was proposed as a good source of anthocyanins.
Second‐home buying and the housing boom and bust
Authors: I. García Daniel 
Published: February 2021

AbstractI estimate the effects of second‐home buying (existing homeowners acquiring additional properties) on the housing boom and bust, by constructing a new measure and using a new identification strategy based on the rise in out‐of‐town demand for second homes in vacation areas during the housing boom. Areas with plausibly exogenous higher second‐home buying experienced a sharper boom and bust: faster growth in house prices and construction employment from 2000 to 2006, and a sharper contraction from 2006 to 2010. The results suggest that changes in credit demand were important in amplifying the recent housing cycle.
Quality of radiology training and role of Royal Australian and New Zealand College of Radiology in supporting radiology trainees in NSW: Results of the first radiology trainee survey
Authors: Kyaw Merribel M , Dedova Irina , Young Noel , Moscova Michelle 
Published: February 2021

AbstractIntroductionThe Royal Australian and New Zealand College radiology training programme is a 5‐year programme with a vast curriculum including reporting and research requirements. Undertaking training can be stressful for trainees who must balance their educational needs and work responsibilities. We undertook the first independent survey of New South Wales (NSW) radiology trainees to evaluate their perceptions about the quality of their training.MethodsFocus groups with trainees from multiple NSW training sites were conducted to construct a survey which was then distributed to all NSW Radiology trainees (n = 118). Data from the survey were analysed, and factors correlating to the overall satisfaction with the programme were explored using Spearman's correlation.ResultsSurvey response rate was 70.3%. Eighty‐nine per cent of trainees were satisfied with their career choice, and 73% were satisfied with the training programme. Majority felt they had a good exposure to cases, modalities and access to resources to complete their training. Trainee satisfaction significantly correlated with a supportive work environment (rs = 0.83, P < 0.0001), which involved supportive consultants (rs = 0.75, P < 0.0001), good peer support (rs = 0.60, P < 0.0001) and their training site respecting work/life balance (rs = 0.62, P < 0.0001). As trainees progressed through the training programme, they became less satisfied, with trainees in years 3 and above being the most dissatisfied.ConclusionNSW radiology trainees are generally satisfied with their training programme and career choices. Trainee satisfaction correlated most strongly with supportive work environment, good consultant support, peer relationships and good work/life balance; satisfaction decreased for senior trainees.
