Unmasking intellectual capital from gender and nationality diversity on university spin-offs’ boards: a study on non-linear effects upon firm innovation
Authors: Prencipe Antonio , Boffa Danilo , Papa Armando , Corsi Christian , Mueller Jens 
Published: March 2022

PurposeThe purpose of this study is to analyze the impact of human capital related to gender and nationality diversity in boards of directors on the innovation of university spin-offs (USOs) in their entrepreneurial ecosystem. Following the intellectual capital (IC) framework and the resource dependence theory, upper echelons theory and critical mass theory, it hypothesizes that the relationship between board diversity and USOs’ firm innovation is non-linear.Design/methodology/approachTo test the research hypotheses empirically, a sample of 827 Italian USOs over the period 2009–2018 was analyzed using zero-inflated Poisson regression modeling. A robustness test was also performed.FindingsGender obstacles remain in USOs’ entrepreneurial ecosystem, with little involvement of women in boards, and the benefits of human capital for firm innovation emerge with increased female representation. Nevertheless, a few foreign-born directors embody valued IC in terms of human capital from an internationally linked entrepreneurial ecosystem, which decreases with more foreign-born directors due to communication costs and coordination problems.Research limitations/implicationsThe emerging non-linear relationships imply that gender- and nationality-diverse boards in USOs constitute critical human capital factors boosting the devolvement of entrepreneurial processes, in terms of firm innovation, in university entrepreneurial ecosystems.Originality/valueThis study contributes significantly to the move from traditional corporate governance analysis through an IC framework, fostering an understanding of the role of human capital and its diversity determinants in spurring firm innovation among USOs considering the university entrepreneurial ecosystem.

These communities support and shape professional development, especially in countries with limited opportunities and constrain like time and distance. This study throws light on the role of VCoP and its impact on the continuous professional development (CPD) of librarians in Pakistan.Design/methodology/approachThis study is carried out with qualitative research methods to understand effects of VCoP on CPD. With a thematic content analysis on the email conversations of a library and information science (LIS) Yahoo mailing group “plagpk”, the impact of virtual communities (VCs) on librarians' professional development in Pakistan over the past 20 years was analyzed.FindingsThis study demonstrates that VCs contribute to professional learning, problem-solving, knowledge creation, professional awareness and identity creation in the LIS field. Further, this study contributes a model to explain the formal and informal professional development for individuals and groups through VCoP engagement.Social implicationsIt is hoped that this study will help the librarian community create, get involved in the VCoP for personal, professional development consciously and create an impact in the profession. The finding of this study is generalizable to any social sciences or humanities professionals VCoPs.Originality/valueThis is one of the first studies in the LIS field to analysis the impact of VCs on the professional development of the librarians.
Effect of low caffeine doses on jumping performance: a meta-analysis
Authors: Grgic J. 
Published: March 2022

Purpose
The purpose of this paper is to explore the effects of low doses of caffeine (<3 mg/kg) on jumping performance using a meta-analysis.

Design/methodology/approach
The search for eligible studies was performed through six databases, with additional backward and forward citation tracking. A random-effects meta-analysis was performed to compare the effects of caffeine vs placebo on jump height. The methodological quality of the included studies was appraised using the physiotherapy evidence database checklist.

Findings
Eight studies were included in the review. They were classified as good or excellent methodological quality. The pooled number of participants across all studies was 203. Four studies provided caffeine in relative doses, ranging from 1 to 2 mg/kg. Four studies provided caffeine supplementation in absolute doses of 80, 150 or 200 mg. The meta-analysis found that caffeine ingestion increased vertical jump height (Cohen’s d: 0.21; 95% confidence interval: 0.10, 0.31; p < 0.001; +3.5%).

Originality/value
The present meta-analysis found that caffeine doses of ∼1 to 2 mg/kg enhance jumping height. The effects observed herein are similar to those with higher caffeine doses, which is relevant as low caffeine doses produce minimal side effects. For most individuals, a caffeine dose of ∼1 to 2 mg/kg is equivalent to an amount of caffeine in an energy drink, one to two cups of coffee, one to two pieces of caffeinated chewing gum or several cups of green tea.
Does top management team’s job mobility experience matter for corporate innovation?
Authors: Jia Jing , Li Zhongtian , Hu Yuanyuan , Tao Baoshan 
Published: March 2022

Purpose
This study aims to investigate whether top management team (TMT)’s job mobility experience is related to firm innovation.

Design/methodology/approach
The authors use different strategies, including a two-stage instrumental model, difference-in-differences analysis based on TMT members’ sudden deaths, propensity score matching and firm fixed-effects model, to mitigate endogeneity concerns.

Findings
The authors find that firms whose TMT experienced more job mobility have better firm innovation. In addition, the authors reveal that the job mobility experience is positively related to engagement in explorative innovation strategies that generate new knowledge. The findings are robust to a battery of tests to alleviate potential endogeneity concerns. Overall, the results highlight the role of job mobility experience in influencing firm innovation.

Originality/value
This study contributes to the rising literature on the determinants of firm innovation. By showing the TMT’s job mobility experience is related to innovation, the authors expand the literature about the economic consequences of the heterogeneous TMT characteristics. Given that firm innovation is essential to competitive advantage, the results should be of interest to a range of stakeholders, including investors, directors and managers and policymakers.

PurposeLimited research focuses on the challenges that exist at the intersection of race and dis/ability for Black men on the autism spectrum in encounters with law enforcement. An interdisciplinary approach is necessary to fully comprehend and mitigate the complex challenges. This conceptual article presents Critical Dis/ability (DisCrit) Theory, a framework usually applied to education, as a lens through which to think about encounters between Black autistic men and police officers. The article concludes with recommendations for collaboration between social scientists, police scholars, law enforcement and the public to improve the outcomes of police encounters involving Black men on the autism spectrum.Design/methodology/approachUsing a literature review and analysis of current events, this conceptual article explores the intersections of race and disability, specifically neurodiversity, in policing using Critical Dis/ability (DisCrit) theory, and its predecessors, Intersectionality Theory and Critical Race Theory (CRT).FindingsAn interdisciplinary approach might be a potential solution to improve police encounters with Black autistic men. Expanding the theoretical frameworks utilized in scholarship about policing might allow for innovative approaches to examine current practices in law enforcement. Collaboration and critical dialogue may yield opportunities for further research and shifts in practice.Originality/valueThis conceptual article uses two incidents from recent events to highlight the need for increased scholarship around the intersections of autism and race, with a particular focus on Black autistic men. It advocates for the use of social science frameworks, namely DisCrit Theory, as a novel way to approach new research regarding race and dis/ability.
Are post-COVID return-to-growth plans gaining priority over transformation?
Authors: Anderson Cindy , Bieck Christian , Marshall Anthony 
Published: March 2022

Purpose
This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies.

Design/methodology/approach
This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.

Findings
This research paper looks at the elements underpinning employee satisfaction and loyalty, as well as how these are related to performance. The questionnaire results revealed that the IT consultant employees were overall satisfied or very satisfied, and in turn were loyal to their current company. This satisfaction drove good job general job performance, but didn’t have the same impact on task performance. Managers are advised to acknowledge and strive to meet the needs of their employees at a human level by deploying empathy and by viewing each individual as being unique, as opposed to just a job role holder.

Originality/value
The briefing saves busy executives, strategists and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.
Buffering role of positive religious coping against the helplessness of elderly people under Covid stress
Authors: Wilson M.J. Antony , Sia Surendra Kumar 
Published: March 2022

Purpose
This study aims to understand the relationship between Covid stress and helplessness among the elderly people in Tirunelveli district of Tamil Nadu, a southern state of India, and moreover, whether positive religious coping can have any influence on this relationship.

Design/methodology/approach
Following a field study approach, data were collected from 187 elderly people aged more than 60 years in different parts of the Tirunelveli district. Moderated regression analysis was carried out to examine the moderating role of positive religious coping on the relationship between Covid stress and helplessness.

Findings
In line with the formulated hypotheses, the findings reveal a significant positive contribution of Covid stress toward the helplessness of elderly people. However, despite Covid stress, the helplessness gets reduced for elderly people executing a higher level of positive religious coping.

Research limitations/implications
The findings substantiate the conservation of resources theory and suggest the role of positive religious coping as a personal resource against the stress experienced by the elderly.

Practical implications
The findings of the present study indicate the responsibility of government agencies, community leaders, family members as well as religious leaders in providing the scope to the elderly for religious interactions as well as practices that may facilitate positive religious coping among them.

Originality/value
The present study is one of its kind to be carried out among community-dwelling elderly under the pandemic crises. Moreover, the buffering role of positive religious coping as a personal resource to withstand the difficult situation has been examined in this study in an empirical manner.
New insights into the drivers of moss‐associated nitrogen fixation and cyanobacterial biomass in the eastern Canadian boreal forest
Authors: Renaudin Marie , Blasi Charlotte , Bradley Robert L. , Bellenger Jean‐Philippe 
Published: March 2022

Abstract

Moss‐associated cyanobacteria nitrogen (N2‐) fixation can contribute to support moss growth and constitutes a major source of new N in boreal forest ecosystems. The biomass of moss‐colonizing cyanobacteria and their N2‐fixation are usually considered linearly correlated. Yet, recent evidence has shown that cyanobacterial biomass and N2‐fixation can be decoupled, suggesting that they are not necessary affected by the same environmental and ecological drivers. Climate and nutrients were reported as affecting moss‐associated N2‐fixation, with equivocal results, whereas drivers of moss cyanobacterial biomass remain unclear. In addition, these drivers are often determined through manipulative experiments (e.g. fertilization and incubation) and remain to be validated with complementary observational studies to help us better understand future impacts of global change on the moss–cyanobacteria symbiosis.

We hypothesized that moss‐associated cyanobacterial biomass is controlled in situ by factors affecting bacterial growth, whereas N2‐fixation is controlled by factors affecting enzymatic reactions.

Using random forests, Spearman correlations and linear mixed‐effects models, we determined the main drivers of cyanobacterial biomass and N2‐fixation of two feather moss species, which were collected over 3 years along a 1000‐km latitudinal transect in the eastern Canadian boreal forest.

We found that temperature, precipitation and phosphorus were the main positive drivers of moss cyanobacterial biomass and that temperature and molybdenum were the main positive drivers of N2‐fixation. Vanadium was a negative driver of N2‐fixation, suggesting the use of alternative nitrogenases by cyanobacteria.

Both cyanobacterial biomass and N2‐fixation were strongly influenced by the moss species and were negatively correlated with moss C:N stoichiometry, highlighting the role of N2‐fixation in moss N enrichment.

Synthesis. We identified for the first time some environmental drivers of moss‐associated cyanobacterial biomass and showed that they contrast with the drivers of N2‐fixation, which should be considered in further research and confirmed in other experimental settings. This is an important advance in our knowledge of moss–cyanobacteria associations, which would greatly help in better predicting the impacts of global change on this symbiosis and on nitrogen inputs in boreal forest ecosystems.
Biological Flora of Britain and Ireland: Fritillaria meleagris
Authors: Tatarenko Irina , Walker Kevin , Dyson Miranda 
Published: March 2022

Abstract

This account presents information on all aspects of the biology of Fritillaria meleagris L. (Snake's Head Fritillary). The main topics are presented within the standard framework of the Biological Flora of Britain and Ireland: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history, and conservation.

Fritillaria meleagris is a perennial spring bulb that grows in wet mesotrophic meadows and wet openings in woodlands. In Britain, it is localised to floodplain meadows but occurs as an intentional introduction in a range of habitats. There are several large populations on the floodplains of the River Thames and its tributaries in Wiltshire, Berkshire and Oxfordshire.

Fritillaria meleagris occurs on mesotrophic alluvium soils often overlaying calcareous gravel with a relatively wide pH range. It favours a high ground water table during winter months and spring followed by good drainage of the soil throughout the summer.

Fritillaria meleagris plants regularly experience prolonged dormancy. From 30% to 99% of plants in a population can remain below‐ground for more than a year.

Fritillaria meleagris produces nectar and is mainly pollinated in April by bumblebee queens in England. Other pollinators include insects of the orders Hymenoptera, Diptera and Lepidoptera, particularly bumblebees, hoverflies and butterflies.

The release of the seeds from the pod in May–June can take a month. Seeds require warm and cold treatments for the embryo to fully form. Air pockets aid seed flotation on the surface of flood water for up to a month. The seeds of Fritillaria meleagris do not form a seed bank, germinating either during flotation or on bare ground.

Fritillaria meleagris declined in Britain during the 20th century due to agricultural improvement and ploughing of floodplain grasslands. In all, 20 or so remaining populations survive in ancient hay meadows. Several of its British locations receive statutory protection as designated sites. However, recent work suggests that F. meleagris was probably introduced to Britain as an ornamental, and the level of protection it receives is therefore likely to change.

Published: March 2022

AbstractAimWe aimed to explore the future roles of nutrition and dietetics professionals, and what capabilities the workforce would need to fulfil these roles.MethodA qualitative interpretive approach was employed. We conducted individual interviews with nutrition and non‐nutrition thought leaders external to the profession. In addition, we conducted focus groups with experts within the nutrition and dietetics profession, academic dietetics educators and students/recent nutrition and dietetics graduates (total sample n = 68). Key nutrition‐related issues and challenges, drivers for change and potential future roles of the profession were explored. Data were analysed using a team‐based thematic analysis approach.ResultsFuture roles of nutrition and dietetics professionals were described as food aficionados, diet optimisers, knowledge translators, equity champions, systems navigators and food systems activists, change makers, activists and disruptors. In addition, science was identified as a uniting framework underpinning the professions. An additional 16 critical capabilities were considered to underpin practice.ConclusionThe results demonstrated that the current and future needs for workforce education and development need to address the impact of climate change, growing inequities, the democratisation of knowledge and the disruption of health and food systems. Education providers, regulators, professional associations and citizens need to work together to realise roles that will deliver on better health for all.

AbstractIntroductionTo evaluate the proportion of cancer patients who received radiation therapy (RT) within 12 months of cancer diagnosis (RTU12) and identify factors associated with RTU12.MethodsThis is a population‐based cohort of individuals with incident cancer, diagnosed between 2013 and 2017 in Victoria. Data linkages were performed between the Victorian Cancer Registry and Victorian Radiotherapy Minimum Dataset. The primary outcome was the proportion of patients who had RTU12. For the three most common cancers (i.e., prostate, breast and lung cancer), the time trend in RTU12 and factors associated with RTU12 were evaluated.ResultsThe overall RTU12 in our study cohort was 26–20% radical RT and 6% palliative RT. Of the 21,735 men with prostate cancer, RTU12 was 17%, with no significant change over time (P‐trend = 0.53). In multivariate analyses, increasing age and lower socioeconomic status were independently associated with higher RTU12 for prostate cancer. Of the 20,883 women with breast cancer, RTU12 was 64%, which increased from 62% in 2013 to 65% in 2017 (P‐trend < 0.05). In multivariate analyses, age, socioeconomic status and area of residency were independently associated with RTU12 for breast cancer. Of the 13,093 patients with lung cancer, RTU12 was 42%, with no significant change over time (P‐trend = 0.16). In multivariate analyses, younger age, male and lower socioeconomic status were independently associated with higher RTU12.ConclusionIn this large population‐based state‐wide cohort of cancer patients, only 1 in 4 had RT within 12 months of diagnosis. There were marked sociodemographic disparities in RTU12 for prostate, breast and lung cancer patients.
Optimizing aerial imagery collection and processing parameters for drone‐based individual tree mapping in structurally complex conifer forests
Authors: Young Derek J. N. , Koontz Michael J. , Weeks JonahMaria 
Published: March 2022

Abstract

Recent advances in remotely piloted aerial systems (‘drones’) and imagery processing enable individual tree mapping in forests across broad areas with low‐cost equipment and minimal ground‐based data collection. One such method involves collecting many partially overlapping aerial photos, processing them using ‘structure from motion’ (SfM) photogrammetry to create a digital 3D representation and using the 3D model to detect individual trees. SfM‐based forest mapping involves myriad decisions surrounding methods and parameters for imagery acquisition and processing, but it is unclear how these individual decisions or their combinations impact the quality of the resulting forest inventories.

We collected and processed drone imagery of a moderate‐density, structurally complex mixed‐conifer stand. We tested 22 imagery collection methods (altering flight altitude, camera pitch and image overlap), 12 imagery processing parameterizations (image resolutions and depth map filtering intensities) and 286 tree detection methods (algorithms and their parameterizations) to create 7,568 tree maps. We compared these maps to a 3.23‐ha ground reference map of 1,775 trees >5 m tall that we created using traditional field survey methods.

The accuracy of individual tree detection (ITD) and the resulting tree maps was generally maximized by collecting imagery at high altitude (120 m) with at least 90% image‐to‐image overlap, photogrammetrically processing images into a canopy height model (CHM) with a twofold upscaling (coarsening) step and detecting trees from the CHM using a variable window filter after applying a moving window mean smooth to the CHM. Using this combination of methods, we mapped trees with an accuracy exceeding expectations for structurally complex forests (for canopy‐dominant trees >10 m tall, sensitivity = 0.69 and precision = 0.90). Remotely measured tree heights corresponded to ground‐measured heights with R2 = 0.95. Accuracy was higher for taller trees and lower for understorey trees and would likely be higher in less dense and less structurally complex stands.

Our results may guide others wishing to efficiently produce broad‐extent individual tree maps of conifer forests without investing substantial time tailoring imagery acquisition and processing parameters. The resulting tree maps create opportunities for addressing previously intractable ecological questions and informing forest management.
