Published: May 2021

PurposeWhile the link between corporate social responsibility (CSR) and corporate reputation (CR) has been well-established in the prior literature, studies that identify boundary conditions to better understand how CSR matters for CR in the eyes of stakeholders are still limited. Incorporating stakeholder theory with upper echelons theory and institutional theory, this study aims to explore whether and how the CSR-CR relationship is influenced by political ideologies (conservatism vs liberalism) of chief executive officers (CEOs), as well as the states in which firms’ headquarters are located.Design/methodology/approachA longitudinal sample of 172 US firms between 2009 and 2014 was collected. Random effects models were used in analyzing the panel data in the study.FindingsThe relationship between CSR and CR is stronger when firms are led by more liberal CEOs or headquartered in more liberal states.Originality/valueThe study highlights the role political ideology plays in improving the effectiveness of the influence of CSR on corporate reputation.
Measures of academy productivity in English championship clubs
Authors: Balassiano Victor , Bullough Steve 
Published: May 2021

Purpose
This study quantifies academy productivity within English football clubs that have competed in the second tier (Championship) between 2017 and 2020. Previous research has outlined that clubs situated underneath the top leagues have an important role in the development of elite professional players. This study aims to examine that level of the pathway further in England.

Design/methodology/approach
The utilisation of academy players was conducted with data from 33 eligible clubs, from 2017/2018 to 2019/2020. Two measures of productivity are defined for comparison: “Utilisation” (the total minutes played by academy graduates) and “Starts” (the number of times an academy player started for the first team). To quantify these measures, players and clubs’ indices were also defined through two perspectives: “global” (proportion of all games played from 2017/2018 to 2019/2020) and “local” (proportion of games the player featured only). Nationality and position were also included.

Findings
Headline findings demonstrate large differences between clubs for the type and proportion of playing opportunities created. The data outlines that academy graduates have greater utilisation and starts in cup competitions, particularly the English Football League cup. Clubs in the sample being relegated from the Premier League into the Championship recorded weaker “utilisation” and “starts” compared to those that competed in the lower divisions. Academies are producing and using a greater proportion of defensive players (goalkeepers, defenders, defensive midfielders) compared to more attacking sectors of the pitch.

Originality/value
This offers useful insight for academy managers, allowing comparisons between clubs. It has implications for future strategies around the role of the academy and approaches to generating player opportunity.
What lessons can Africa learn from the social determinants of COVID‐19 spread, to better prepare for the current and future pandemics in the continent?
Authors: Ngepah Nicholas 
Published: May 2021

AbstractThis paper examines the determinants of the spread of coronavirus disease 2019 (COVID‐19) in Africa, based on the framework of social determinants of health. Applying Poisson Pseudo Maximum Likelihood (PPML) and quantile regressions to panel data and country‐specific socioeconomic background data from 53 African countries, the study finds that enhancing capacity for early testing helps for timeous uncovering of cases, early isolation and contact tracing for effective control of the spread. Other factors such as managing of international movements through reduction of international exposure and ensuring better sanitation and hygiene were found to be relevant in diminishing COVID‐19 spread, whereas alcohol consumption and population density heighten the spread. The work also highlights that stringent measures will be counter‐productive unless they are coupled with measures to create and preserve livelihoods, together with humanitarian relief assistance to the poorest segments of the population. The results are robust to alternative techniques. As policy recommendations, we implore African governments to the promotion of sustainable livelihoods and social safety nets as measures to accompany stringent lockdowns; and good sanitation programmes to become a lifestyle of citizens. Careful attention should be paid to the socioeconomic trade‐off in respect of international travel restrictions given the high dependence of most African economies on tourism.
Breaking the Managerial Silencing of Worker Voice in Platform Capitalism: The Rise of a Food Courier Network
Authors: Kougiannou Nadia K. , Mendonça Pedro 
Published: May 2021

AbstractThis paper examines food couriers’ utilization of voice mechanisms as mobilization against employer silencing within platform capitalism. The concepts of ‘worker silence’ and ‘worker voice’ are used to facilitate an understanding of the way in which workers respond to workplace problems, as well as their capacity to respond within this specific context. Findings illustrate the role of technology as a facilitator but also inhibitor of worker voice. In particular, online food delivery companies’ over‐reliance on algorithmic management and their online app drove couriers to silence. However, in reaction to managerial silencing, we show that couriers are not passive recipients of forces beyond their control, and attempt to explore new trajectories and modes of voice in order to influence their working conditions. Implications for theory and practice are discussed.

Published: May 2021

AbstractWorldwide milk production is predominantly founded on indoor, high‐concentrate feeding systems, whereas pasture‐based feeding systems are most common in New Zealand and Ireland but have received greater attention recently in countries utilizing conventional systems. Consumer interest in ‘pasture‐fed’ dairy products has also increased, arising from environmental, ethical, and nutritional concerns. A substantial body of research exists describing the effect of different feeding strategies on the composition of milk, with several recent studies focusing on the comparison of pasture‐ and concentrate‐based feeding regimes. Significant variation is typically observed in the gross composition of milk produced from different supplemental feeds, but various changes in the discrete composition of macromolecular components in milk have also been associated with dietary influence, particularly in relation to the fatty acid profile. Changes in milk composition have also been shown to have implications for milk and dairy product processability, functionality and sensory properties. Methods to determine the traceability of dairy products or verify marketing claims such as ‘pasture‐fed’ have also been established, based on compositional variation due to diet. This review explores the effects of feed types on milk composition and quality, along with the ultimate effect of diet‐induced changes on milk and dairy product functionality, with particular emphasis placed on pasture‐ and concentrate‐based feeding systems.

AbstractThe migration study of nano‐Ag migration from polylactic acid (PLA) films was studied. Samples treated by high‐pressure food processing (0, 100, 200, 300, and 400 MPa pressure) were soaked in acetic acid solution and incubated at 20 °C for 90 days. At the end of storage, nano‐Ag particles (AgNPs) migration from the PLA/AgNPs composite film treated under 200 MPa high pressure was the lowest. However, AgNPs migration was accelerated under 400 MPa high pressure. High‐pressure processing (200 MPa) could cause denser structure and higher crystallinity degree in films than other treatments. Lower amount of AgNPs induced a decline in the intensity of specific characteristic peaks. The diffraction peak intensity of α‐crystal for the film sample treated with 400 MPa was the lowest on day 60. The crystallization index of the PLA matrix changed with different high‐pressure processing. The result indicated that appropriate high‐pressure food processing could effectively suppress AgNPs migration from PLA‐based film while contacting with acidic acid food simulant.Practical ApplicationThe release of nanoparticles from food packaging material is a very important matter when the migration is concerned with regulatory and toxicity issues. The study described the migration kinetic of AgNPs from PLA nanocomposite film into acidic food simulant after different high‐pressure food processing. The results indicated that the PLA/AgNPs nanocomposite film was safe for acidic food after high‐pressure treatment.

AbstractImmune checkpoint inhibitors (ICIs) have achieved prominent efficacy in the treatment of numerous cancers, which is the most significant breakthrough in cancer therapy in recent years. However, ICIs are associated with a series of immune‐related adverse events (irAEs). Pneumonitis is an uncommon but potentially fatal irAE. In the case reported here, a patient with advanced small cell lung cancer (SCLC) had rapid progression of disease following chemotherapy and received ICIs. The patient experienced severe immune‐related hyperthermia followed by immune‐related pneumonitis. Fortunately, a good clinical response was achieved after the patient received corticosteroids and tocilizumab.
The giant willow aphid (Tuberolachnus salignus) and its effects on the survival and growth of willows
Authors: Jones Trevor G. , Min Tun Kyaw , Minor Maria , Clavijo McCormick Andrea 
Published: May 2021

AbstractThe giant willow aphid (Tuberolachnus salignus) is an invasive pest that can attain large populations on willows (Salix spp.). This has the potential to have a negative impact on the extensive use of willows for soil conservation, and as a source of pollen and nectar for honey bees in New Zealand.
A willow nursery field trial was established to evaluate the aphid populations, and the survival and growth of young plants of several willow species and hybrids, during two growing seasons from planting.
The willow species and hybrids varied widely in their susceptibility to the aphid, with large aphid populations and plant mortality in the most susceptible willows, and reductions in plant growth in all but aphid‐resistant willows. The effects on the plants were not seen in the first season, but occurred during the second season.
The aphid can be expected to have some negative impacts in New Zealand, with reductions in growth of some willows commonly used for soil conservation, and for pollen and nectar for honey bees.

Published: May 2021

AbstractObjectiveTo evaluate the influence of surgery start time (SST) and other patient‐ and therapy‐related variables on the risk for early implant failure (EIF) in an academic setting.Material and MethodsData were extracted from the electronic health records of 61 patients who had at least one EIF and 140 age‐ and gender‐matched, randomly selected, non‐EIF controls. Bivariate and multivariable analyses were performed to identify relevant associations between EIF and different variables, such as SST.ResultsIncidence of EIF was not significantly associated with SST (HR: 1.9 for afternoon implant placement, 95% CI: 0.9–3.9; p = .105). Other factors that were associated with a significantly increased risk for EIF in a multivariable model were pre‐placement ridge augmentation (HR: 7.5, 95% CI: 2.2–25.1; p = .001), intra‐operative complications (HR: 5.9, 95% CI: 2.2–16.3; p < .001), simultaneous soft tissue grafting (HR: 5.03, 95% CI: 1.3–19.5; p = .020), simultaneous bone grafting (HR: 3.7, 95% CI: 1.6–8.8; p = .002), and placement with sedation (HR: 3.4, 95% CI: 1.5–7.5; p = .002).ConclusionsWhile SST was not associated with the occurrence of EIF in our cohort, other variables, such as ridge augmentation prior to implant placement, simultaneous bone or soft tissue grafting, intra‐operative complications, implant placement with sedation, and number of implants in the oral cavity, were associated with an increased risk for this adverse event.

Published: May 2021

AbstractBackgroundWe and others have noticed consistent staining of sebaceous glands with PReferentially expressed Antigen in MElanoma (PRAME). We aimed to determine whether PRAME was as sensitive, specific, and interpretable as adipophilin for distinguishing sebaceous neoplasms (SNs) from other neoplasms.MethodsTwenty SNs and 32 control cases were stained for PRAME and adipophilin. Extent of staining was scored as follows: 0, no staining; 1, <5% positivity; 2, 5% to 50% positivity; and 3, >50% positivity. Intensity was scored as negative, weak, moderate, or strong. A composite score was determined by adding the scores for extent and intensity.ResultsPRAME had positive composite scores in all 20 SNs in the more differentiated areas, whereas adipophilin had positive composite scores in 19/20 cases. PRAME showed positivity in the basaloid cells in 15/16 cases, whereas adipophilin was positive in 14. Among controls, PRAME and adipophilin had positive composite scores in 3/32 cases and 6/32 cases, respectively.ConclusionsPRAME and adipophilin are comparable in terms of distribution and intensity for staining sebocytes. In the basaloid cells, PRAME expression is often more diffuse and easier to detect than adipophilin. In comparing the SNs to the controls, PRAME was more sensitive and more specific than adipophilin. PRAME could be used as an additional marker of sebaceous differentiation in everyday practice.
Granuloma annulare – is it a paraneoplastic condition for malignant lymphoma?
Authors: Müller Cornelia Sigrid Lissi , Vogt Thomas 
Published: May 2021

SummaryIn recent years, an association between granuloma annulare and the occurrence of malignant cutaneous lymphomas in the sense of a facultative paraneoplasia has been observed several times. The aim of the present work is to provide an overview of the currently available literature on granuloma annulare as well as an analysis of its association with cutaneous lymphomas. Using the example of two patients with granuloma annulare and associated cutaneous lymphomas, we would like to sensitize clinically active dermatologists and dermatopathologists to the possible association between these two diseases.Characteristic features and clinicopathological signs are discussed, which should raise suspicion of an associated malignant lymphoma. It is recommended to rule out an underlying cutaneous and/or extracutaneous lymphoma in unusual clinical constellations (for instance distribution pattern, subjective complaints, age at first manifestation, lack of response to conventional therapy), especially in the absence of other known clinical triggers of granuloma annulare such as insect bites, trauma or varicella‐zoster infections, among others. However, in individual cases the criteria mentioned here justify lymphoma screening.
Changes in theta and alpha oscillatory signatures of attentional control in older and middle age

Published: May 2021

AbstractBackgroundRecent behavioural research has reported age‐related changes in the costs of refocusing attention from a temporal (rapid serial visual presentation) to a spatial (visual search) task. Using magnetoencephalography, we have now compared the neural signatures of attention refocusing between three age groups (19–30, 40–49 and 60+ years) and found differences in task‐related modulation and cortical localisation of alpha and theta oscillations. Efficient, faster refocusing in the youngest group compared to both middle age and older groups was reflected in parietal theta effects that were significantly reduced in the older groups. Residual parietal theta activity in older individuals was beneficial to attentional refocusing and could reflect preserved attention mechanisms. Slowed refocusing of attention, especially when a target required consolidation, in the older and middle‐aged adults was accompanied by a posterior theta deficit and increased recruitment of frontal (middle‐aged and older groups) and temporal (older group only) areas, demonstrating a posterior to anterior processing shift. Theta but not alpha modulation correlated with task performance, suggesting that older adults' stronger and more widely distributed alpha power modulation could reflect decreased neural precision or dedifferentiation but requires further investigation. Our results demonstrate that older adults present with different alpha and theta oscillatory signatures during attentional control, reflecting cognitive decline and, potentially, also different cognitive strategies in an attempt to compensate for decline.
Prefrontal corticotropin‐releasing factor neurons impair sustained attention via distal transmitter release

Published: May 2021

AbstractThe prefrontal cortex (PFC) supports cognitive processes critical for goal‐directed behavior. Although the PFC contains a high density of corticotropin‐releasing factor (CRF) neurons, their role in cognition has been largely unexplored. We recently demonstrated that CRF neurons in the caudal dorsomedial PFC (dmPFC) of rats act to impair working memory via activation of local CRF receptors. However, there is heterogeneity in the neural mechanisms that support the diversity of PFC‐dependent cognitive processes. Currently, the degree to which PFC CRF neurons impact other forms of PFC‐dependent cognition is unknown. To address this issue, the current studies examined the effects of chemogenetic manipulations of PFC CRF neurons on sustained attention in male rats. Similar to working memory, activation of caudal dmPFC CRF neurons impaired, while inhibition of these neurons or global CRF receptor antagonism improved, sustained attention. However, unlike working memory, the sustained attention‐impairing effect of PFC CRF neurons was not dependent on local CRF receptors. Moreover, CRF infusion into the caudal dmPFC or other medial PFC subregions had no effect on task performance. Together, these observations demonstrate that while caudal dmPFC CRF neurons impair both working memory and sustained attention, these actions involve distinct neural circuits (local CRF release for working memory and extra‐PFC release for sustained attention). Nonetheless, the procognitive actions of systemically administered CRF antagonists across both tasks are similar to those seen with attention deficit hyperactivity disorder‐related treatments. Thus, CRF antagonists may have potential for use in the treatment of PFC cognitive dysfunction.
Fatigue failures from defects in additive manufactured components: A statistical methodology for the analysis of the experimental results

Published: May 2021

AbstractThe fatigue response of additive manufactured (AMed) components is generally controlled by the defect population, and the models for assessing the fatigue response of AMed parts have to take into account the distribution of defect size and the intrinsic scatter associated to the fatigue response. In the present paper, a statistical methodology for analyzing the results of tests on AMed specimens failed due to cracks originating from defects is proposed. The procedure involves the estimation of the distribution of the fatigue life, which is considered dependent on the applied stress amplitude and on the defect size. Thereafter, all the experimental failures are shifted at a reference number of cycles to failure or stress amplitude, making it possible to compare data obtained at different stress levels or number of cycles to failure. The proposed method has been successfully validated on literature dataset, proving its effectiveness and general validity.
