What colour are you? Smartphone addiction traffic lights and user profiles
Authors: San-Martín Sonia , Jiménez Nadia 
Published: November 2021

PurposeThe key concern nowadays is smartphone addiction and user profiles. Following the risk and protective factors framework, the authors aim to characterize smartphone users according to two levels: (1) individual: referred to the use (i.e. boredom proneness, compulsive app downloading smartphone addiction) and (2) microsystem: referred to family and peers (i.e. family harmony and phubbing). Besides, the authors will derive useful managerial implications and strategies.Design/methodology/approachFirst, an extensive literature revision and in-depth interviews with experts were employed to identify the addiction-related variables at the individual and microsystem level. Second, information was collected from a sample of 275 Spanish smartphone users, and a K-means clustering algorithm was employed to classify smartphone users.FindingsThe proposed traffic lights schema identifies three users’ profiles (red, yellow and green) regarding their smartphone addiction and considering individual and microsystem critical variables.Originality/valueThis study proposes a practical and pioneer traffic lights schema to classify smartphone users and facilitate each cluster's strategies development.

Published: November 2021

PurposeThis study aims to examine the effect of human resource management (HRM) in mitigating negative effects of Lean management and Six Sigma (LM&SS) on employee well-being in health care. The authors subdivide well-being into three components: happiness, trust and health.Design/methodology/approachThis is a cross-sectional, multisite survey study in internal service units of hospitals. Data analyzed using multivariate regression come from a sample of 1,886 survey respondents (42 units,N= 218 supervisors,N= 1,668 employees) in eight Dutch academic hospitals that have implemented LM&SS.FindingsThe present study findings show no or weak effects of LM&SS on the happiness and health component of employee well-being. In addition, the authors found a significant but weak direct positive effect (ß= 0.07) of the LM&SS bundle on the trusting relationships component of well-being. Therefore, moderating effects of HRM practices on the relationship between LM&SS and employee well-being seem less relevant because an existing relationship between LM&SS and employee well-being is a prerequisite for moderation (Hayes, 2009). There were unexpected side effects. Inspired by research that discusses direct effects of HRM on employee well-being, the authors tested this relationship and found that HRM has a direct positive effect on trust and happiness of employees in health care. For the health component of well-being, the present results show a weak negative effect of HRM.Practical implicationsThis study results in a cautiously optimistic view about LM&SS in health care, provided that it is applied in a targeted manner (to improve the performance of their processes) and that HRM is strategically aligned with the goals of LM&SS to improve employees’ happiness and trusting relationships.Originality/valueUnique features of the study are the focus on the consequences for employees’ well-being related to LM&SS in health care, the role of HRM in regard to this relationship and the participation of all eight Dutch academic hospitals in this research.
“I had no idea until now”: preparing doctoral students in education for the professoriate
Authors: Renbarger Rachel L. , Rehfeld David Michael , Sulak Tracey 
Published: November 2021

PurposeWith the number of doctoral degrees awarded increasing and full-time and tenure-track jobs decreasing, doctoral graduates are entering a fierce job market. Lack of knowledge and support about navigating the job market can impact graduates' mental health and chances of securing long-term employment, but many graduates claim their programs provide little professional development in this area. The purpose of this study is to understand doctoral students' job preparation after participating in a departmental seminar.Design/methodology/approachThe current explanatory sequential mixed methods, single case study investigated students' perceptions following a year-long seminar in job market navigation.FindingsStudents attending the seminar did not differ from those who did not attend on feelings of preparedness, number of application documents completed, or curriculum vita quality scores.Research limitations/implicationsResearchers may have limited ability to implement graduate student interventions given the power structures of faculty life and the lack of graduate student time.Practical implicationsThe results suggest informal seminars may not be enough to support doctoral students' job market skills.Social implicationsThis has implications for department chairs and deans to create faculty development opportunities to pivot to a student-centered culture rather than relying on faculty or external support to help graduate students prepare for the job market.Originality/valueThis case study provides insight as to how graduate students' job market anxieties are at odds with the current demands and structure of educational doctoral programs.
Vernacular and World Heritage Impact Assessment: the case study of Patmos
Authors: Dipasquale Letizia , Montoni Lucia , Montacchini Alessia , Mecca Saverio 
Published: November 2021

PurposeThis article aims to raising awareness on the potential of the application of the Heritage Impact Assessment (HIA) methodology – developed by ICOMOS in 2011 – with a focus on UNESCO World Heritage sites that are characterized by a widespread presence of vernacular architecture, one of the most vulnerable and fragile typologies of heritage.Design/methodology/approachStarting from a theoretical introduction about the recognition of vernacular heritage into the international non-governmental panorama, and the dynamics that are mostly affecting it, the present contribution focuses on the case study of the Chora of Patmos (Greece), a UNESCO World Heritage site since 1999. The research has been carried out as follows: (1) comparative analysis of selected literature for the theoretical part; (2) field research; (3) interdisciplinary research for understanding the features of the site and assessing potential risks; (4) project design and assessments of the potential impacts.FindingsThe pivotal application of the HIA method on the case study of Patmos highlighted the importance of the methodology as an essential tool for facilitating management and safeguarding WH sites from possible threats due to development projects on vernacular architecture.Originality/valueThe originality of the research presented here lies in the connection between three different topics: vernacular architecture, Heritage Impact Assessment and Sustainable World Heritage Management. In fact, its goal is to bring cultural heritage management and sustainable development closer together, by emphasizing that HIA should not be used as a tool to hinder development, but as a practice for shaping and evaluating projects that might alter or compromise the integrity and authenticity of WH sites in a sustainable and balanced way.
The innovation ecosystem in rural tourism and hospitality – a systematic review of innovation in rural tourism
Authors: Madanaguli Arun , Kaur Puneet , Mazzoleni Alberto , Dhir Amandeep 
Published: November 2021

PurposeInnovation in rural tourism and hospitality (RT) is a complex process that involves the exchange of knowledge and resources between many actors and the interrelationships between those actors in the business environment. The purpose of this paper is to provide structure to this “knowledge and resource ecosystem” through a thorough systematic review of the extant literature.Design/methodology/approachThe current study uses a time-tested and reproducible systematic literature review process to identify and analyse 79 research papers that have discussed innovation in RT.FindingsThrough content analyses, this review identifies critical stakeholders in the innovation ecosystem, as well as the enabling and hindering roles these stakeholders play in innovation. The thematic analysis uncovers three key research foci: stakeholders and their roles, outcomes of innovation and business model innovation. The review also identifies types of innovation and critically analyses the bibliographical research profile. The authors summarise the findings in an RT innovation ecosystem model, which includes the various actors and their knowledge and resource sharing roles within the business environment.Originality/valueThis is one of the first systematic reviews to concentrate on RT innovation and, within that focus, on knowledge and resource networks in particular rather than on innovation in tourism in general, which was the focus of prior reviews. The authors encourage cross-pollination of ideas by introducing theories from the strategic management, innovation, knowledge management and business model innovation literature wherever appropriate. To consolidate and present the findings on the innovation process’s antecedents and outcomes, the authors present an ecosystem of innovation within the RT framework.
Can textual analysis solve the underpricing puzzle? A US REIT study
Authors: Paulus Nino Martin , Koelbl Marina , Schaefers Wolfgang 
Published: November 2021

PurposeAlthough many theories aim to explain initial public offering (IPO) underpricing, initial-day returns of US Real Estate Investment Trust (REIT) IPOs remain a “puzzle”. The literature on REIT IPOs has focused on indirect quantitative proxies for information asymmetries between REITs and investors to determine IPO underpricing. This study, however, proposes textual analysis to exploit the qualitative information, revealed through one of the most important documents during the IPO process – Form S-11 – as a direct measure of information asymmetries.Design/methodology/approachThis study determines the level of uncertain language in the prospectus, as well as its similarity to recently filed registration statements, to assess whether textual features can solve the underpricing puzzle. It assumes that uncertain language makes it more difficult for potential investors to price the issue and thus increases underpricing. Furthermore, it is hypothesized that a higher similarity to previous filings indicates that the prospectus provides little useful information and thus does not resolve existing information asymmetries, leading to increased underpricing.FindingsContrary to expectations, this research does not find a statistically significant association between uncertain language in Form S-11 and initial-day returns. This result is interpreted as suggesting that uncertain language in the prospectus does not reflect the issuer's expectations about the company's future prospects, but rather is necessary because of forecasting difficulties and litigation risk. Analyzing disclosure similarity instead, this study finds a statistically and economically significant impact of qualitative information on initial-day returns. Thus, REIT managers may reduce underpricing by voluntarily providing more information to potential investors in Form S-11.Practical implicationsThe results demonstrate that textual analysis can in fact help to explain underpricing of US REIT IPOs, as qualitative information in Forms S-11 decreases information asymmetries between US REIT managers and investors, thus reducing underpricing. Consequently, REIT managers are incentivized to provide as much information as possible to reduce underpricing, while investors could use textual analysis to identify offerings that promise the highest returns.Originality/valueThis is the first study which applies textual analysis to corporate disclosures of US REITs in order to explain IPO underpricing.

AbstractGuarana (Paullinia cupana) is a plant from the Amazon region with cultural importance. Despite its early ancestral use by indigenous tribes, the first reports regarding the benefits of guarana consumption for human health were published in the 19th century. Since then, the use of guarana seed in powder and extract forms has been studied for its diverse effects on human health, such as stimulating, anti‐inflammatory, antioxidant, anticancer, hypocholesterolemic, and anti‐obesity effects. These effects are attributed to the high content of bioactive compounds found in guarana seeds, especially methylxanthines and flavonoids. In fact, the Brazilian Food Supplement Law has officially acknowledged guarana as a source of bioactive compounds. The number and diversity of studies focused on guarana and human health are increasing; thus, organizing and describing the available evidence on guarana and its applications is necessary to provide a framework for future studies. In this narrative review, we have organized the available information regarding guarana and its potential effects on human health. Guarana produces unique fruits with great potential for human health applications. However, the available evidence lacks human studies and mechanistic investigations. Future studies should be designed considering its applicability to human health, including intake levels and toxicity studies.
Decolonising methodologies: Emergent learning in island research
Authors: Farbotko Carol , Watson Phillipa , Kitara Taukiei , Stratford Elaine 
Published: November 2021

AbstractThis article documents an attempt to decolonise our approach to methodology to explicitly show respect for islands and their islanders. Our twin starting points are an awareness of a turn to the Anthropocene in studies related to islands and an appreciation of the imperative to think outside colonial frames. The Anthropocene has been conceived as both an enduring colonising force and a significant moment in decolonisation, and islands have been viewed as emblematic of the Anthropocene, so the relationship between them is complex. These dynamic conceptions raise dilemmas for those wanting to apply methodologies to island research and negotiate ethical relations across multiple geographies and knowledge systems. For those whose cultures have been subjected to colonial oppressions, there are emotional and material costs and varied risks in participating in attempts to decolonise island research. Settler researchers seeking to ally themselves with others to advance such agendas and aspirations may slow or damage decolonising practices if they act without appropriate permissions, respectful commitments to support and understand decolonisation, and preparedness to engage in deep learning about what decolonisation of knowledge means. With these challenges in mind, we detail an approach to decolonising one of our own island research projects in ways that are enriched by a Tuvaluan concept, Fale Pili, which means treating a neighbour’s problems as your own.

Published: November 2021

AbstractIn this paper, the interface polymerization method was used to prepare Osmanthus essential oil microcapsules. The optimal preparation process of Osmanthus essential oil microcapsules was explored as follows: the dosage ratio of Osmanthus essential oil to N100 was 6:1, the reaction temperature was 70°C, and the reaction time was 2 h. The encapsulation efficiency of Osmanthus essential oil microcapsules could reach 80.31%. The particle size distribution, morphology, chemical structure, and thermal stability of the obtained microcapsules were characterized by laser particle size analyzer, scanning electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis. The release kinetics and storage stability experiments of the microcapsules were studied. The results showed that the average volume diameter of the microcapsules was 101.2 µm. The microcapsules were in the shape of full spheres, with a smooth surface, low viscosity, and high elasticity. Microencapsulation improved the thermal stability of Osmanthus essential oil and promoted the slow release of essential oil. The synthesized microcapsules showed good storage stability under refrigerated and dark conditions, which indicated that microcapsules had broad application prospects in food, medicine, and other fields.Practical ApplicationIn this study, we prepared a polyurea membrane to encapsulate Osmanthus essential oil microcapsules by interfacial polymerization. The encapsulation conditions of the microcapsules were optimized and the structure of the microcapsules was characterized in this study. The results showed that microcapsules had a full spherical shape with a smooth surface, high elasticity, good sustained‐release ability, good thermal stability, and storage stability. These properties indicated that microcapsules have good application prospects and can be used as a high‐quality flavor with a long residual effect and high thermal stability for food and cosmetic scope.

AbstractAdvances in long‐read sequencing technology and genome assembly provide an opportunity to improve the pig genome and reveal the full range of structural variations (SVs) between local Chinese and European pigs. To date, little is known about the genomes of some unique Chinese indigenous breeds, such as the Ningxiang pig. Here, we report the sequencing and assembly of a highly contiguous Ningxiang pig genome (NX) via an integration of PacBio single‐molecule real‐time sequencing, Illumina next‐generation sequencing, BioNano optical mapping and Hi‐C (chromosome conformation capture) approaches. The assembled genome comprises 2.44 Gb with a contig N50 of 26.1 Mb and 418 contigs in total. These contigs are organized into 121 scaffolds with a scaffold N50 of 139.0 Mb. More than 99.1% of the assembled sequence could be localized to 19 pseudochromosomes and is annotated with 20,914 protein‐coding genes and 34.04% repetitive sequences. Comparisons between the NX and European Duroc assemblies revealed many SVs in genes involved in the immune system, nervous system, lipid metabolism and environmental adaptation. The genetic variants include 47 Chinese domestic pig‐specific SVs and the associated 74 genes may contribute to the differences in domestic traits compared to European pigs. Moreover, single nucleotide polymorphisms (SNPs) identified from whole genome resequencing data of 73 Chinese pigs, representing 17 geographically isolated breeds, showed their specific genetic variations, population structure and evolutionary patterns. Finally, we explore transcriptional regulation in the first intron of the MYL4 gene, as the genomic SV (281‐bp deletion) in Ningxiang pig promotes its subcutaneous fat compared to European pig breeds. This work identifies a set of Asian‐specific SVs and SNPs, which will be important resources for modern pig breeding and genetic conservation.
Advertising Expenditures on Media Vehicles and Sales*
Authors: Oz Seda , Istanbulluoglu Doga 
Published: November 2021

ABSTRACTThis research aims to advance the literature by identifying the association between four advertising media vehicles (Internet, press, outdoor, television) and contemporaneous sales. Previous research highlights the influence of advertising on firm value but does not delve into the effects of advertising media vehicles. Employing primary data, which detail the advertising expenditures of 88 publicly traded companies over 11 years, we empirically show a positive association between television and outdoor advertising expenditures and contemporaneous sales. However, we do not find any significant results for press and Internet advertising. We investigate the moderating effect of the growth opportunities, industry sectors, and firm size. Our study offers important evidence that the contemporaneous relationship between sales and advertising expenditures varies by media vehicle. We discuss the implications of our findings for the matching principle, a principal concept in accrual accounting.
Political homophily, bifurcated social reality, and perceived legitimacy of the 2020 US presidential election results: A four‐wave longitudinal study
Authors: Blanchar John C. , Norris Catherine J. 
Published: November 2021

AbstractWe report the results from a four‐wave longitudinal study (N = 951–1349) investigating perceptions of the 2020 US Presidential Election as legitimate. Specifically, the role of homophily (“love of same”) was examined in creating politically homogenous social and informational networks that facilitate and amplify polarized perceptions of the election's legitimacy and belief in voter fraud across time. Consistent with our hypotheses, Trump voters’ susceptibility to misinformation about voter fraud and refusals to accept the election results as legitimate drastically increased to the extent to which they were entrenched in politically homophilic networks. Biden voters modestly strengthened their views of the election results as legitimate when entrenched in politically homophilic networks. Moreover, the influence of politically homophilic networks in facilitating this polarization grew stronger with the passage of time. Longitudinal modeling revealed that, among Trump voters, politically homophilic networks decreased perceptions of election legitimacy through increased belief in voter fraud.
