Innovative drivers for family business models in tourism
Authors: Arcese Gabriella , Valeri Marco , Poponi Stefano , Elmo Grazia Chiara 
Published: October 2020

PurposeThe aim of this paper is to verify whether, in the tourism sector, the “family business model” is an important development opportunity and, in particular, if it is an innovation driver for this industry development. In the literature, there is no conclusive evidence of this for the tourism sector. In this context, the authors investigate personal and family needs and preferences alongside the relationship between family business model, growth and profit maximization and the development of tourism businesses through innovation drivers.Design/methodology/approachTo develop this topic, the authors conducted an extensive literature review considering the scientific papers published and contained mainly in database in the last 10 years (2010–2020) and focused the attention on the last five years. The authors ran content and structural analysis on the collected sources by main scientific databases (EBSCO, Scopus, Thomson Reuter, etc.). Based on a systematic literature review, the analysis was conducted using statistical criteria and bibliometric indicators. In detail, the authors used systematic literature review, bibliometric analysis and automatic text analysis (ATA) tools for identified lexicon analysis and strategic keywords and used statistical correlation to classify the different approaches in the literature and to outline the orientations of the various research groups.FindingsFrom this analysis, the correlation between tourism, hospitality, entrepreneurship, life cycle and innovation dynamics was analysed. Important research gaps are identified, and future research priorities are suggested. Implications for both family business and tourism theory are discussed.Originality/valueWhile the intersection between tourism management and family business model has been established in the literature, the number of related publications is still limited. Against this background, a literature review as a total analysis was an adequate and practicable research methodology. This paper proposes a comprehensive literature review and a reflection on the potential developments and applications for family business in the tourism sector. Authors also suggest several research directions that have not been adequately investigated yet. In particular, scholars do not seem to have caught all the implications of innovation adoption, especially for SMEs and family ownerships in tourism.

Authors: Jorif Maria , Burleigh Cheryl 
Published: October 2020

PurposeThe purpose of this paper is to explore perspectives of secondary (9–12) teachers on how to sustain growth mindset concepts within instructional practices as well as identifying barriers to sustainment.Design/methodology/approachThis study employed an exploratory case study to obtain the lived experiences of participants. An inductive analysis process was utilized on the data collected through structured interviews and a semi-structured focus group.FindingsFour major themes emerged from an in-depth analysis process: embed growth mindset practices in daily classroom instruction, communicate verbal affirmations and implement growth mindset learning tasks, allow students to experience academic successes and failures and teachers should receive continual support.Research limitations/implicationsThe study was limited to secondary grades (9–12). Therefore, it is recommended to expand the study to gradesK-8.Originality/valueDue to a gap in the literature, this study provided insights into sustaining an innovative psychological approach, growth mindset, within academic instruction. Growth mindset concepts have been supported through the work of seminal researcher Carol Dweck and other prevalent educational researchers (e.g. Robert Marzano) to provide teachers with effective classroom instructional practices that can academically progress students.

Published: October 2020

PurposeThis study is an attempt to evaluating the growth of scientific literature in the domain of coronavirus and Covid-19 pandemic research based on scientometric indicators: prolific countries and relative citation impact (RCI); influential institutions; author analysis and network, h-index and citation; DC (degree of collaboration), CC (collaboration coefficient), MCI (modified collaboration index) in the subject domain of coronavirus and Covid-19 research.Design/methodology/approachThe authors adopted approaches to obtain the literature data from Scopus database from 2000 to 2020 by conducting a systematic search using keywords related to the studied subject domain. In total, 15,297 numbers of records were considered for the literature analysis considering the real significant growth of this subject domain. This study presented the scientometric analysis of these publications. Furthermore, statistical correlations have been used to understand the collaboration pattern. Visualization tool VOSviewer is used to construct the co-author network.FindingsThe present study found that 53.57% (8,195) of the research documents published on the open-access platform. Journal of Virology was found to be most preferred journal by the researcher producing around 839(5.48%) articles. USA and China dominate in the research output, and the University of Hong Kong has produced the highest number of research paper 547(3.58%). A significant portion of the research documents are published in the subject domain of medicine (49.70%), followed by immunology and microbiology (35.72%), and biochemistry, genetics and molecular biology subject domains (22.32%). There has been an unparalleled proliferation of publications on COVID-19 since January 2020 and also a significant distribution of research funds across the globe.Research limitations/implicationsThe study exclusively examines 15,297 research outputs which have been indexed in the Scopus database from 2000 to 2020 (till 01 April 2020). Thus, documents published in any other different channels and sources which are not covered in Scopus are excluded from the purview of research.Practical implicationsIt will be beneficial for researchers and practitioners worldwide for understanding the growth of scientific literature in the coronavirus and COVID-19 and identifying potential collaborator.Originality/valueConsidering the global impact and social distress due to the outbreak of COVID-19 pandemic, this study is significant in the present scenario for identifying the growth of scientific literature in this field and evolving of this domain of research around the globe. The research results are useful to identify valuable research patterns from publications and of developments in the field of coronavirus and COVID-19.
Corporate social responsibility impact on talent retention among Generation Y
Authors: Zainee Intan Azurin , Puteh Fadilah 
Published: October 2020

PurposeAs the new emerging workforce, Generation Y (Gen Y) is said to be demanding, influential and possessing strong bargaining power. This study examines the impact of corporate social responsibility (CSR) on employee retention among Gen Y in the accounting profession. CSR is widely researched subject due to its applicability in multidisciplinary fields and industries. This research intends to investigate the nexus between CSR and human capital disciplines. It employs Carroll's pyramid of CSR as the main theoretical framework to establish its relationship with talent retention among Gen Y employees. This study has a threefold aim: (1) to determine the level of CSR awareness, (2) to determine the relationship between CSR dimensions and talent retention and (3) to examine the effect of CSR dimensions on talent retention.Design/methodology/approachThe paper opted for an exploratory study using the structured questionnaire. A total of 377 Gen Y accountants who are currently working in accounting firms located in Klang Valley, Malaysia, were involved as respondents. Data were analyzed using descriptive, correlation and regression analyses to answer the research objectives.FindingsThe paper provided empirical insights about the impact brought by CSR practices in financial-based firms on employee retention. It was found that all CSR elements, as suggested by Carroll, have a significant relationship with employees’ retention. The interaction between the CSR elements and employee retention accounts for 16% of the research model. Based on the multiple regression analysis, it was found that only two CSR elements are the significant predictors of employee retention among Gen Y in the case of financial-based firms in Malaysia.Research limitations/implicationsThis research covers Gen Y employees in accounting firms; thus, generalization is not applicable to other generations. Besides, the predictors of the research study utilize Carroll’s pyramid of CSR. Therefore, future research studies are encouraged to validate the research model into other sectors. Other models of CSR could also be used.Practical implicationsThis paper includes implication for the organization to understand employee retention practices on Gen Y who are currently dominating the workforce.Originality/valueThis paper fulfills an identified need to study how CSR practices could enhance employee retention among Gen Y in the organization.

Published: October 2020

PurposeThis study presents a fuzzy synthetic evaluation of the challenges of smart city realisation in developing countries, using Nigeria as a case study. By defining and delineating the problems faced by the country, more viable directions to attaining smart city development can be achieved.Design/methodology/approachThe study adopted a post-positivist philosophical stance with a deductive approach. A structured questionnaire was used to gather data from built environment professionals involved in the delivery of Nigerian public infrastructures. Six dimensions of the challenges of smart cities were identified from literature and explored. They are governance, economic, social, technological, environmental and legal issues. Data gathered were analysed using Cronbach alpha test for reliability, Shapiro-Wilks test for normality, Kruskal-Wallis H-test for consistency and fuzzy synthetic evaluation test for the synthetic evaluation of the challenges of smart city attainment.FindingsThe findings revealed that all six assessed dimensions have a significant impact on the attainment of smart cities in Nigeria. More specifically, issues relating to environmental, technological, social and legal challenges are more prominent.Originality/valueThe fuzzy synthetic approach adopted provides a clear, practical insight on the issues that need to be addressed before the smart city development can be attained within developing countries.

AbstractTo fulfil their growth and reproductive functions, trees develop a three‐dimensional structure that is subject to both internal and external constraints. This is reflected by the unique architecture of each individual at a given time. Addressing the crown dimensions and topological structure of large tropical trees is challenging considering their complexity, size and longevity. Terrestrial laser scanning (TLS) technology offers a new opportunity for characterising and comparing these properties across a large number of individuals and species.In the present study, we specifically developed topology and geometry metrics of crown architecture from TLS data and investigated how they correlated with metrics of tree and crown form, crown position and shade tolerance.Fifty‐nine trees belonging to 14 coexisting canopy species in semideciduous forests of Cameroon were scanned with TLS and reconstructed using quantitative structural models (QSMs). The species belonged to different shade‐tolerance groups and were sampled in different crown positions. Crown‐form metrics and branch topology metrics were quantified from the TLS data, and principal component analysis (PCA) was used to study how the 59 sampled trees were distributed along axes of architectural diversity. Allometric scaling parameters derived from West Brown and Enquist (WBE) metabolic theory were also quantified from the QSMs, and their correlations with the PCA axes were evaluated.The results revealed that the branch topology and crown‐form metrics were not correlated since similar topologies could lead to contrasting crown forms. Crown form, but not branch topology, changed with tree shade tolerance, while convergence in tree topology and towards expected WBE parameters was observed for all trees reaching dominant crown positions independent of species shade tolerance.This convergence is interpreted as resulting from a liberation effect of canopy trees from side‐shading constraints, leading to crown development processes through sequential reiteration.A freePlain Language Summarycan be found within the Supporting Information of this article.
Towards linking species traits to demography and assembly in diverse tree communities: Revisiting the importance of size and allocation
Authors: Iida Yoshiko , Swenson Nathan G. 
Published: October 2020

AbstractOne of the important goals in plant ecology is to form a mechanistic link between the underlying processes driving the dynamics and structure of communities and the observed demography (i.e., growth, survival, and recruitment) and assembly (i.e., distribution of species) in a community via traits. Although the importance of traits to performance is evident, their direct links to demography and the resulting assembly in tree communities are often found to be fairly weak probably because a single “mean” trait value for a species is not enough to capture complex life histories. In this paper, we review how traits at the organ‐level and at the whole plant level, demography, and assembly change with size in diverse tropical forests and summarize what know so far. We argue the importance of trait‐based life‐history strategies revealing trait‐environment‐demography linkages across ontogenetic stages to achieve the ultimate goal of forming a mechanistic link between the underlying processes driving the dynamics and structure of communities and the observed demography and assembly.
Evaluation and applicability of Alere iCup DX 14 for rapid postmortem urine drug screening at autopsy
Authors: Towler Steven , Concheiro Marta , Pearring Sue , Rodda Luke N. 
Published: October 2020

AbstractPerforming point‐of‐care urine drug screen testing at autopsy by a forensic pathologist may provide an early indication of the presence of analytes of interest during autopsy. An evaluation for the screening of 14 classes of common drugs of abuse in postmortem urine by the point‐of‐care screening device, Alere iCup DX 14, is presented. One hundred ninety postmortem urine samples were screened with the iCup occurring at autopsy by the forensic pathologist. Positive and negative results obtained from the screening kit were evaluated against confirmatory test results obtained using routine forensic toxicology analyses that employed LC‐MS/MS and GC‐MS to detect a combination of over 85 common drugs of abuse and medications. Sensitivity for each respective iCup drug class ranged from 66% (buprenorphine) to 100% (methadone, tricyclic antidepressants). Specificity for each respective iCup drug class ranged from 89% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, 3,4‐methylenedioxymethamphetamine, methadone). Positive predictive values ranged from 44% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, methylenedioxymethamphetamine, methadone), while negative predictive values ranged from 96% (methamphetamine) to 100% (barbiturates, methadone, tricyclic antidepressants). A high false‐positive rate was yielded by the benzodiazepine class. The lack of fentanyl screening in the point‐of‐care device is a significant limitation considering its prolific prevalence in forensic casework. The results obtained in the study should be acknowledged when considering the use of the Alere iCup DX 14 in the context of postmortem casework to help indicate potential drug use contemporaneously with autopsy and when requiring such preliminary results prior to the release of a final forensic toxicology report.
Eligibility criteria for extracorporeal cardiopulmonary resuscitation at Auckland City Hospital: A retrospective cohort study

Published: October 2020

AbstractObjectiveExtracorporeal cardiopulmonary resuscitation (ECPR) is a promising adjunct to routine advanced cardiac life support. Growing worldwide interest in ECPR‐use has seen more tertiary centres offering ECPR programmes. New Zealand's nationwide extracorporeal membranous oxygenation service is provided at Auckland City Hospital (ACH). Despite the potential benefits of ECPR, it is currently only offered on an ad hoc basis. It remains unknown whether ACH would manage sufficient numbers of patients to warrant an ECPR programme.MethodsA 12‐month retrospective cohort study of the medical records of patients who were managed for cardiac arrest in the resuscitation room of the ED was conducted. Patient characteristics and clinical outcomes were analysed descriptively and audited against a unique set of criteria for a hypothetical ECPR programme.ResultsBetween 1 July 2018 and 30 June 2019, 286 patients died or had a cardiac arrest for which they were managed at ACH. Sixty‐five of these patients had an in‐hospital cardiac arrest in the ED. Seven (10.8%) of these patients were deemed eligible for hypothetical ECPR. Only one of these seven patients survived to hospital discharge with full neurological recovery.ConclusionsAn ECPR programme at ACH using standardised and agreed criteria may benefit a small number of patients and improve rates of survival to hospital discharge with preservation of neurological function. An ECPR guideline would help clarify for referring services cases that are appropriate for extracorporeal membranous oxygenation consideration, rather than discussing on an ad hoc basis.
On the future fermentation
Authors: Chen Guo‐Qiang , Liu Xinyi 
Published: October 2020

SummaryMicrobial fermentations produce chemicals, materials, biofuels, foods and medicines for many years. The processes are less competitive compared to chemical industries. To increase its competitiveness, technologies must be developed to address the following issues including fresh water shortage, heavy energy consumption, microbial contaminations, complexity of sterile operations, poor oxygen utilization in the cultures, food‐related ingredients as substrates, low substrate to product conversion efficiency, difficult cells and broth separation, large amount of wastewater, discontinuous processes, heavy labour involvements and expensive bioreactors. Future industrial fermentations should be more effective with the above issues reasonably addressed. Recently, extremophilic bacteria have well addressed the above issues for future fermentation.

AbstractBackgroundDue to the complex pathogenesis, the molecular mechanism of nonalcoholic steatohepatitis (NASH) remains unclear. In this study, we aimed to reveal the comprehensive metabolic and signaling pathways in the occurrence of NASH.MethodsC57BL/6 mice were treated with high‐fat diet for 4 months to mimic the NASH phenotype. After the treatment, the physiochemical parameters were evaluated, and the liver tissues were prepared for untargeted metabolomic analysis with ultraperformance liquid chromatography coupled with quadrupole time‐of‐flight mass spectrometry. Then, three relevant Gene Expression Omnibus (GEO) datasets were selected for integrative analysis of differentiated messenger RNA and metabolites.ResultsThe levels of phosphatidylethanolamine (PE) (16:1(9Z)/20:4(5Z,8Z,11Z,14Z)), oleic acid, and sphingomyelin (SM) (d18:0/12:0) were significantly increased, and the content of adenosine was severely reduced in NASH mice. The integrated interpretation of transcriptomic and metabolomic data indicated that the glycerophospholipid metabolism and necroptosis signaling were evidently affected in the development of NASH. The high level of SM (d18:0/12:0) may be related to the expression of acid sphingomyelinase (ASMase), and the elevated arachidonic acid was coordinated with the upregulation of cytosol phospholipase A2 (cPLA2) in the necroptosis pathway.ConclusionsIn summary, the inflammatory response, necroptosis, and glycerophospholipid may serve as potential targets for mechanistic exploration and clinical practice in the treatment of NASH.

Published: October 2020

AbstractWe used multiple methods to examine livestock depredation by African lions (Panthera leo), spotted hyaenas (Crocuta crocuta), leopards (Panthera pardus) and black‐backed jackals (Canis mesomelas) in livestock enclosures across the Maasai steppe of Northern Tanzania. In this landscape, pastoralists keep cattle, goats, sheep and donkeys. All are vulnerable to depredation by carnivores. Various factors, such as boma characteristics, landscape attributes and attacks by multiple carnivores, were analysed to understand the best predictors of livestock loss at a boma. We found that livestock depredation was significantly correlated with the number of carnivore species that attacked the boma, the number of boma fences and proximity to protected areas, rivers and roads. Bomas with one fence experienced more loss than those with two walls of fencing. We also found that livestock depredation increased farther from protected areas (β = 0.50, SE = 0.10) and rivers (β = 0.39, SE = 0.10) and closer to roads (β = −0.28, SE = 0.11). These results highlight the complex interaction of fine‐scale factors that influence carnivore depredation of livestock at any given boma. We recommend that mitigation address the range of factors, including the structural integrity of a boma, landscape attributes and multiple carnivore raids.
