When being hospitable hurts (staff experiences of bullying from hotel guests)
Authors: Doe Frederick , Essiaw Mary Naana 
Published: December 2021

PurposeThe hospitality industry is one of Ghana's key economic contributors. It is an industry that has significant indigenous investment. The sector also brings in foreign exchange for Ghana. In 2019, it generated $325 m through tourist visits. This makes the hospitality industry critical for the attraction of foreign direct investments. The research was therefore aimed at examining the business environment of the hospitality industry for evidence of negative factors that can hamper its greater contribution to the attainment of Goal 8 of the 17 Sustainable Development Goals of the UN such as guest-bullying and the incivility in hospitality occupations.Design/methodology/approachA convenience sampling method was used to select 346 samples out of the accessible 3,500 targeted population from 38 hotels in the capital city of Ghana, Accra, comprising of junior to senior employees of various departments. The questionnaires were scripted from a paper-based to digital format supported by the Opine software installed on tablets and smartphones, to enable complete adherence to all coronavirus disease 2019 (COVID-19) safety protocols. The study used a regression to ascertain the relationships between the dependent variables and the independent variables.FindingsThe study found the “Level of Permissiveness for Guests” positively and significantly “encouraged” guests to bully staff, while “Management and Staff Laxity” negatively but significantly explained guest bullying behaviour.Originality/valueThe study makes the first attempt in context to shed light on workplace bullying which represents one of the main factors that can inhibit or erode any gains or attempts to foster the achievement of Goal 8 of the 17 Sustainable Development Goals of the UN which is to create “Decent Work and Economic Growth”.
Evaluating the effectiveness of the fatigue and shift working risk management strategy for UK home office police forces: a pilot study
Authors: James Lois , James Stephen , Hesketh Ian 
Published: December 2021

PurposeTo evaluate the effectiveness of a fatigue-management training and sleep health promotion intervention in a sample of officers from UK Home Office Police Forces.Design/methodology/approachUsing a pre- and post-design we exposed 50 officers from selected UK police forces to a fatigue-management training intervention. Pre- and post-intervention data collection included wrist actigraphy, a physiological and objective measure of sleep quantity and quality, as well as surveys including the Pittsburg Sleep Quality Index (PSQI), the World Health Organization Quality of Life (WHOQOL) instrument, the Epworth Sleepiness Scale (ESS), the Perceived Stress Scale (PSS) and the PTSD Checklist (PCL-5).FindingsWe found the training significantly increased sleep quantity by 25 min per 24-h period, from 6.9 h to 7.3 h (f = 9.2; df = 519; p = 0.003), and improved sleep quality scores from 84% before the intervention, to 87% after the training (f = 10.6; df = 519; p = 0.001).Research limitations/implicationsContinued research is necessary to guide nationwide implementation of fatigue-management and sleep health promotion programs.Practical implicationsOur findings show that a fatigue-management training resulted in a significant and meaningful increase in sleep among police officers.Originality/valueThis is the first piece of research to emerge from a full population survey (response rate 16.6%) of the UK police service exploring issues of sleep and fatigue.
Stock returns, oil prices and leverage: evidence from US firms
Authors: Amin Md Ruhul , Mollick Andre Varella 
Published: December 2021

PurposeThis paper aims to investigate how the relation between stock returns of US firms and West Texas Intermediate (WTI) oil prices is affected by leverage from 1990 to 2020.Design/methodology/approachThis paper examines how the relationship between stock returns of US firms and WTI oil prices is affected by leverage from 1990 to 2020 using a fixed-effect model estimation framework.FindingsResults from the fixed-effect regression models suggest that leverage effects on stock returns are pervasive both in aggregate and cross-industry levels, while the mining industry is more sensitive. In addition to the positive oil price effects attenuated by leverage at the aggregate level, the authors observe stronger marginal effects of leverage only for the mining sector. Being more exposed to commodity prices, the positive effects of oil prices on stock returns in the mining sector are offset by large debt ratios. Asymmetries, effects of debt maturity structure and implications are also discussed.Research limitations/implicationsThis study is grounded on the contemporary cash flow claim of leverage NOT on the long-run effect of leverage considering cash flow constraints. The oil price increase is assumed to represent an advancement of the overall economy. This study does not capture the oil prices response to some other economic forces and vice-versa.Practical implicationsMining companies should therefore reduce the stock of debt with respect to their assets to make possible the “pass-through” from oil prices to the stock market.Originality/valuePreviously undocumented and the authors show that leverage reduces the total effect of oil prices on stock returns, consistent with the hypothesis. Asymmetric and debt maturity structures effects are also discussed.
Lexicon of pandemics: a semantic analysis of the Spanish flu and the Covid-19 timeframe terminology
Authors: Lanza Claudia , Folino Antonietta , Pasceri Erika , Perri Anna 
Published: December 2021

PurposeThe aim of this study is a semantic comparative analysis between the current pandemic and the Spanish flu. It is based on a bilingual terminological perspective oriented to evaluate and compare the terms used to describe and communicate the pandemic's issues both to biomedical experts and to a non-specialist public.Design/methodology/approachThe analysis carried out is a terminological comparative investigation performed on two corpora, the first containing scientific English articles, the second Italian national newspapers' issues on two pandemics, the Spanish flu and the current Covid-19 disease, towards the detection of semantic similarities and differences among them through the implementation of computational tasks and corpus linguistics methodologies.FindingsGiven the cross-fielding representativeness of terms, and their relevance within specific historical eras, our study is conducted both on a synchronic and on a diachronic level to discover the common lexical usages in the dissemination of the pandemic issues.Originality/valueThe study presents the extraction of the main representative terms about two pandemics and their usages to share news about their trends among the population and the integration of a topic modeling detection procedure to discover some of the main categories representing the lexicon of the pandemics with reference to a list of classes created by external thesauri and ontologies on pandemics. As a result, a detailed overview of the discrepancies, as well as similarities, retrieved in two historical corpora dealing with a common subject, i.e. the pandemics' terminology, is provided.
Time and temporality in library and information science
Authors: Haider Jutta , Johansson Veronica , Hammarfelt Björn 
Published: December 2021

PurposeThe article introduces selected theoretical approaches to time and temporality relevant to the field of library and information science, and it briefly introduces the papers gathered in this special issue. A number of issues that could potentially be followed in future research are presented.Design/methodology/approachThe authors review a selection of theoretical and empirical approaches to the study of time that originate in or are of particular relevance to library and information science. Four main themes are identified: (1) information as object in temporal perspectives; (2) time and information as tools of power and control; (3) time in society; and (4) experiencing and practicing time.FindingsThe paper advocates a thorough engagement with how time and temporality shape notions of information more broadly. This includes, for example, paying attention to how various dimensions of the late-modern time regime of acceleration feed into the ways in which information is operationalised, how information work is commodified, and how hierarchies of information are established; paying attention to the changing temporal dynamics that networked information systems imply for our understanding of documents or of memory institutions; or how external events such as social and natural crises quickly alter modes, speed, and forms of data production and use, in areas as diverse as information practices, policy, management, representation, and organisation, amongst others.Originality/valueBy foregrounding temporal perspectives in library and information science, the authors advocate dialogue with important perspectives on time that come from other fields. Rather than just including such perspectives in library and information science, however, the authors find that the focus on information and documents that the library and information science field contributes has great potential to advance the understanding of how notions and experiences of time shape late-modern societies and individuals.
CEO cognitive trust, governmental support and marketing innovation: empirical evidence from Chinese small, medium and micro enterprises
Authors: Gu Jiafeng , Ardito Lorenzo , Natalicchio Angelo 
Published: December 2021

Purpose
This study aims to verify the influence of chief executive officer (CEO) cognitive trust and governmental support on marketing innovation. Additionally, it evaluated the influence of CEO cognitive trust on the marketing innovation of small, medium and micro enterprises (SMMEs).

Design/methodology/approach
The authors empirically assessed the impact of CEO cognitive trust on SMME marketing innovation. Furthermore, the authors examined the mediating effect of governmental support on this relationship. The authors then studied a sample of 1,770 SMMEs in China by applying partial least squares structural equation modeling.

Findings
The authors found that CEO cognitive trust was negatively associated with marketing innovation. Moreover, governmental support has a competitive mediating effect on this relationship. Thus, while governmental support is urgently needed to enhance the marketing innovation of SMMEs, CEO cognitive trust negatively impacts this relationship.

Research limitations/implications
This study empirically establishes the importance of CEO cognitive trust and governmental support as antecedents in SMME marketing innovation. This contributes to the knowledge base of the management field, adding to important streams in the wider business literature, such as marketing studies, leadership management, strategic management and innovation. While the model is parsimonious, the relationships it highlights are robust and can be generalized to other contexts.

Practical implications
Managers must not only have high levels of trust and authority but must also embody these characteristics rationally. Simultaneously, managers must actively establish a trusting relationship with the government, thereby improving their company’s ability to integrate government policy information while also actively seeking governmental support. These measures are helpful in enhancing the marketing innovation capabilities of SMMEs.

Social implications
SMMEs occupy an important position in all countries’ economies and their vitality directly determines the strength of the economy. Formulating reasonable marketing strategies will help enhance market competitiveness and promote the rapid development of SMMEs.

Originality/value
The literature on marketing innovation has paid little attention to CEO cognitive trust, while CEOs’ cognitive characteristics are an increasingly relevant antecedent in SMME marketing innovation. This study analyzed CEO cognitive trust as a possible antecedent of marketing innovation activities in SMMEs, with this influence path being evaluated. This study extends the current knowledge in this field by considering the effects of CEO cognitive trust on marketing innovation.
Power law scaling relationships link canopy structural complexity and height across forest types
Authors: Atkins Jeff W. , Walter Jonathan A. , Stovall Atticus E. L. , Fahey Robert T. , Gough Christopher M. 
Published: December 2021

AbstractForest canopy structural complexity (CSC), an emergent ecosystem property, plays a critical role in controlling ecosystem productivity, resource acquisition and resource use‐efficiency; yet is poorly characterized across broad geographic scales and is difficult to upscale from the plot to the landscape.Here, we show that the relationship between canopy height and CSC can be explained using power laws by analysing lidar‐derived CSC data from 17 temperate forest sites spanning over 17 degrees of latitude. Across three plant functional types (deciduous broadleaf, evergreen needleleaf and mixed forests), CSC increases as an approximate power law of forest height. In evergreen needleleaf forests, increases in canopy height do not result in increases in complexity to the same magnitude as in other forest types.We attribute differences in the slope of height:complexity relationships among forest types to: (a) the limited diversity of crown architectures among evergreen conifer trees relative to broadleaf species; (b) differences in how vertical forest layering develops with height; and (c) competitive exclusion by needleleaf species. We show support for these potential mechanisms with an analysis of 4,324 individual trees from across 18 National Ecological Observatory Network sites showing that crown geometry‐to‐tree height relationships differ consistently between broadleaf and needleleaf species.Power law relationships between forest height and CSC have broad implications for modelling, scaling and mapping forest structural attributes. Our results suggest that forest research and management should consider the nonlinearity in scaling between forest height and CSC and that the nature of these relationships may differ by forest type.A freePlain Language Summarycan be found within the Supporting Information of this article.

Abstract

Floral scents are considered major attractants for pollinator species and scent composition is likely to be under pollinator‐mediated selection. Relatively, few studies have investigated geographical variation in floral scents in plant species with generalist pollination, and little is known about the mechanism behind this variation, often interpreted as the result of local adaptation to pollinators without considering phenotypic plasticity. One possible way to investigate this question is to compare floral bouquets both in natural populations and in populations reared under controlled conditions.

We compared the identity and proportions of volatile organic compounds (VOCs), collected on plants both in the field and in the greenhouse, emitted by four generalist plant species found in six calcareous grasslands distributed along an environmental and diversity gradient. We recorded pollinator visits in the field to document geographical variation of pollinator communities associated with each plant species. We then analysed the relation between VOCs and pollinator variation using a redundancy analysis (RDA).

We found that VOC composition differed among species and among populations, but also between field and greenhouse. The RDA showed a significant effect of the variation in pollinator communities associated with the variation in the VOCs emission, even after removing potential confounding effects, suggesting some stability in the compounds attractive to a given pollinator species. However, only one species showed significant geographical differences among populations tested in both conditions, suggesting local genetic adaptation. Another species showed geographical variation in VOC proportion in the field, but these results were not confirmed by the greenhouse extractions, suggesting an effect of phenotypic plasticity.

Our findings suggest that geographical variation of floral scent may, in some cases, be genetically based and possibly explained by pollinator‐mediated selection, even in generalist pollinated species, which represent the large majority of pollination systems. However, our results also showed significant phenotypic plasticity, suggesting that studies of floral volatiles must be conducted in natural populations to obtain a representative picture of the signal that can be potentially perceived by pollinators.

A novel hybrid method based on discontinuous Galerkin method and staggered‐grid method for scalar wavefield modelling with rough topography
Authors: Huang Jiandong , Hu Tianyue , Song Jianyong , Li Yandong , Yu Zhenzhen , Liu Lichao 
Published: December 2021

ABSTRACTIn recent years, the discontinuous Galerkin method and the finite‐difference method have been widely applied to simulate seismic wave propagation. However, few studies have focused on the combination of the finite‐difference method with the discontinuous Galerkin method. We develop a new hybrid algorithm based on domain decomposition that combines the high efficiency of the finite‐difference method with the flexibility of the discontinuous Galerkin method. A computational domain is decomposed into two types of subregions where the finite‐difference method is applied in the main part of the model, whereas the discontinuous Galerkin method is employed to handle the complex structure with a free surface or caves. Total variation diminishing Runge–Kutta time discretization is used to enhance the stability of implementation. The approach inherits the advantages of the discontinuous Galerkin method and the finite‐difference method and does not need a transition zone, which reduces the computational cost caused by the additional conversion. In addition, some mesh patterns are provided to make the discontinuous Galerkin method domain discretized as needed without changing the grid size of the finite‐difference method region, which makes our hybrid algorithm more flexible. Numerical experiments prove that our hybrid scheme is capable of dealing with complex structures and maintains moderate computational efficiency.
Female executive leadership and corporate social responsibility
Authors: Hyun Soonchul , Kim Jong Min , Han Jeongsoo , Anderson Mark 
Published: December 2021

AbstractWe examine how increased female participation in top executive leadership affects corporate social responsibility (CSR). Applying a long‐window, event study approach with matching, we first document that CSR ratings improve with increased female participation in the top executive team, consistent with expectations based on previous research. Then, we examine specific ways that female participation impacts CSR decision‐making. We predict and find that increased female participation brings more attention to remediating CSR concerns. We also predict and find that, in the uncertain economic times following the global financial crisis, increased female participation moderated addition of new CSR strengths.
Preventing postpartum weight retention following antenatal lifestyle intervention: One year postpartum follow up of the Healthy Lifestyles in Pregnancy (HeLP‐her) randomised controlled trial
Authors: Li Heidi Z. , Boyle Jacqueline A. , Harrison Cheryce L. 
Published: December 2021

Antenatal lifestyle interventions optimise gestational weight gain, yet longer‐term efficacy on postpartum weight retention is unclear. Overall, 228 pregnant women <15 weeks gestation were randomised to intervention (four behavioural self‐management sessions) or control (generic health information). Median weight retention at 12 months postpartum was significantly reduced in the intervention with a between group difference of −2.3 (−2.8 (−5.9 to 0.35) vs −0.5 (−2.6 to 2.1) kg, respectively P < 0.05, (n = 75) ± 6.3 kg vs −0.5 ± 4.7 kg, respectively, P < 0.05) and associated increased self‐weighing behaviours, compared with the control group (regular weighing: 68% vs 43%, P < 0.01). Results demonstrate the efficacy of a low‐intensity, behavioural lifestyle intervention in limiting postpartum weight retention.

Published: December 2021

AbstractObjectiveWomen with polycystic ovary syndrome (PCOS) have a worsened metabolic profile but the progression of cardiometabolic features over time is unclear. Understanding this natural history is a key priority in PCOS research and vital for guiding the prevention and management of this common condition. We explored cardiometabolic changes that are observed in women with PCOS compared to those without PCOS across the life course.Design, Patients and MeasurementsA systematic review of longitudinal cohort studies was conducted across MEDLINE, EMBASE, Ovid PsycInfo, CINAHL PLUS and EBM reviews between 15 January 2020 and 11 February 2021. Eligible studies included participants with or without PCOS diagnosed according to the 2003 Rotterdam or the 1990 National Institutes of Health (NIH) criteria. We included studies that were published from the year 1990 to 2021 with data on cardiometabolic outcomes as per the PCOS core outcomes set.ResultsThere were 31 longitudinal studies with 28,316 participants from four continents. At the start of follow up, participants were aged between 1 year and 49 years with a follow‐up period ranging from 2 to 32 years. Changes in BMI and the risk of coronary heart disease were similar in adult women with and without PCOS. Women with PCOS had a higher risk of Type 2 diabetes than their non‐PCOS counterparts. Evidence for the majority of all other outcomes was conflicting and with inadequate data.ConclusionUnderstanding the natural history of PCOS and particularly changes in cardiometabolic features remains challenging. Existing literature is extensive but heterogeneous and inconsistent. Longitudinal studies in unselected populations are needed to provide high‐quality data in this area.
Kontaktekzem auf Haarkosmetikprodukte: Aktuelle Empfehlungen zur Diagnostik
Authors: Thomas Zita‐Rose Manjaly , Jamiolkowski Dagmar , Chantraine Sibylla , Steveling‐Klein Esther , Hofmeier Kathrin Scherer , Hartmann Karin 
Published: December 2021

ZusammenfassungHaarkosmetikprodukte wie Shampoos, Färbe‐, Bleich‐ oder Glättmittel enthalten häufige Kontaktallergene. Diese können insbesondere bei Friseuren, aber auch bei ihren Kunden und bei Selbstanwendern, zu allergischen Kontaktekzemen führen. Während sich Kontaktekzeme bei Friseuren in der Regel als Handekzem manifestieren, sind bei Kunden und Selbstanwendern vor allem Kopf, Hals und Gesicht betroffen. Wir schlagen einen zweistufigen Algorithmus zur strukturierten allergologischen Abklärung mittels Epikutantestung bei Verdacht auf ein haarproduktbedingtes allergisches Kontaktekzem vor. Als ersten Schritt empfehlen wir die Testung der Deutsche Kontaktallergie‐Gruppe (DKG)‐Standardreihe, DKG‐Externareihe, DKG‐Konservierungsmittelreihe, DKG‐Friseurreihe, DKG‐Duftstoffreihen sowie (vor allem bei Friseuren) der DKG‐Gummireihe. Wird mittels der standardisierten Testreihen kein auslösendes Allergen identifiziert, sollte spätestens in einem zweiten Schritt – bei entsprechendem Verdacht – eine personalisierte Testung mit Eigensubstanzen, wie Shampoos, Haarsprays und Färbemitteln, durchgeführt werden.
