Authors: Juneja Sagar , Pratap Rajendra , Sharma Rajnish 
Published: September 2021

Purpose
Propagation characteristics of millimeter wave (mmW) frequencies that are being explored for implementing 5G network are quite different from sub 3GHz frequencies in which 4G network is operating, and hence antenna design for mmW 5G network is going to be significantly different. The purpose of this paper is to bring forth the unique challenges and opportunities of planar antenna design for mmW 5G network.

Design/methodology/approach
A lot of notable contemporary work has been investigated for this study and reported in this paper. A comparison of 4G and 5G technologies has been carried out to understand the difference between the air interface of two technologies that governs the antenna design. Important research gaps found after collating the work already done in the field have been bullet pointed for the use by many researchers working in this direction.

Findings
Several antenna design considerations have been laid out by the authors of this work, and it has been claimed that mmW 5G antenna design must satisfy these design considerations. In addition, prominent research gaps have been identified and thoroughly discussed.

Originality/value
As research in the field of mmW antenna design for 5G applications is still evolving, a lot of work is currently being done in this area. This study can prove to be important in understanding different challenges, opportunities and current state-of-art in the field of mmW planar antenna design for 5G cellular communication.
Examining the role of customers' intrinsic motivation on continued usage of mobile banking: a relational approach
Authors: Banerjee Shubhomoy , Sreejesh S. 
Published: September 2021

PurposeThis research seeks to establish the roles of marketer-driven relationship-building strategies – relationship-marketing orientation and knowledge sharing with customers on intrinsic customer motivation and the continued usage of mobile banking apps.Design/methodology/approachAn online survey was conducted among 342 m-banking users in India. Data were analyzed and the hypotheses were tested using structural equation modeling.FindingsRelationship-marketing orientation was found to have a positive and significant influence on customer intrinsic motivation and knowledge sharing with customers. Customer intrinsic motivation was found to play a dual role as a driver of continued mobile banking usage and as an intervening mechanism between relationship-marketing orientation and continued usage of mobile banking.Research limitations/implicationsThis research was conducted only in one country. It was therefore not possible to consider varying regulations across markets and their effects on continued usage of mobile banking.Originality/valueFirst time in the m-banking literature, this research establishes the pivotal role of intrinsic customer motivation in the continued usage of mobile banking. While evaluating drivers of continued usage of m-banking, most studies considered various aspects of the technology itself. This research instead evaluates consumer-centric and marketer-led antecedents in driving the continued usage of mobile banking.
Increasing efficiency in healthcare: a showcase in an orthopedic outpatient clinic
Authors: Heijink Andras , van den Heuvel Jaap , Schoonhoven Marit 
Published: September 2021

PurposeCost reduction is a current topic within healthcare. This article aims to show how Lean Six Sigma can be applied to make the orthopedic outpatient clinic within a hospital more cost-effective. The approach can, of course, also be applied to other departments.Design/methodology/approachWe did a pareto analysis to select the project with the greatest potential. The most expensive and time-consuming activity is repeat consultations; these number around 7,500 per year and are all performed by the orthopedic surgeon. This limits the number of appointments available for new patients. Moreover, the hospital gets a fixed amount of money for each new patient. Therefore, reducing the number of repeat consultations is beneficial to both the patient and the hospital.FindingsBased on data analysis, we found that the number of repeat consultations performed by orthopedic surgeons can be reduced by 19.5%. An additional 10.8% can be performed by phone, which will probably save the surgeons considerable time. The freed-up time can be used for new patients. Another result is that hospital visits by patients for repeat consults can be reduced by 20.3%. We believe that these efficiency improvements are also possible for other departments/processes. Finally, in the given case, the freed-up time for new patients could generate 465K euros.Originality/valueThis article shows that 20% of the care provided by the physicians (i.e. repeat consults) is omissible. While most projects focus on doing the same number of activities in a more efficient way, this paper shows that it is also possible to reduce the amount of medical care provided. We believe that it would be beneficial to take such a perspective when looking at other processes and departments within healthcare.

PurposeThis research aims to study the economic conditions of fishermen living in the coastal area of Kabupaten Pesisir Selatan.Design/methodology/approachThe method used is a descriptive analysis method supported by a participatory planning method. The importance of primary data is to understand deeply the real problems of fishermen in the field, collected by using a survey method such as field observations, in-depth interviews by gathering fishermen and related stakeholders in the area, undertaking forum group discussion, workshop and seminar. Secondary data are necessary to support the primary data analysis.FindingsThe results showed that there is an abundance of marine resources, but the economic condition of fishermen is far from expected. The income from fishing is not enough to feed their family's daily needs due to low catching productivity and raw fish selling price. The regency government and province do not have clear and concrete policies to resolve firmly and thoroughly the economic problems of fishermen living in the coastal areas.Research limitations/implicationsThis study succeeds in providing two breakthrough strategic policies to improve the economic conditions of fishermen, i.e. institutional and entrepreneurial innovations.Practical implicationsBoth strategic policies have a mutual relationship. Therefore, the implementations have to integrate with one another and be executed simultaneously in a single coastal area management system.Social implicationsBupati as a top policymaker in this region must take full responsibility for the successful implementation of these two strategic policies.Originality/valueProviding new ideas to solve the main problem of fishermen living in the coastal area in Indonesia.
A keystone mutualism promotes resistance to invasion

Published: September 2021

Abstract

It is not uncommon for one or a few species, and their interactions, to have disproportionate effects on other species in ecological communities. Such keystone interactions might affect how communities respond to the invasion of non‐native species by preventing or inhibiting the establishment, spread or impact of non‐native species.

We explore whether a keystone mutualism among a hummingbird–mistletoe–marsupial promotes ecological resistance to an invasive pollinator, the bumblebee Bombus terrestris, by comparing data collected at sites prior to bumblebee invasion to data collected 11 years after the invasion in sites with and without the keystone mutualism.

We built pollination networks and focused on network motifs, regarded as building blocks of networks, to identify the central pollinators and estimate the change in their interactions after invasion of B. terrestris. We also estimated the interaction rewiring across the season in post‐invasion networks and tested it as a possible mechanism explaining how the keystone mutualism increased ecological resistance to invasion.

We found two times more species in post‐invasion sites with the keystone mutualism than in post‐invasion sites without the keystone mutualism. Moreover, we found that invasive bumblebee reduced the strength and interaction niche of the five central pollinator species while increasing its own strength and interaction niche, suggesting a replacement of interactions. Also, we found that the keystone mutualism promoted resistance to B. terrestris invasion by reducing its negative impacts on central species. In the presence of the keystone mutualism, central species had three times more direct interactions than in sites without this keystone mutualism. The higher interaction rewiring, after invasion of B. terrestris, in sites with the keystone mutualism indicates greater chances of central pollinators to form new interactions and reduces their competence for resources with the non‐native bumblebee.

Our results demonstrate that a keystone mutualism can enhance community resistance against the impacts of a non‐native invasive pollinator by increasing species diversity and promoting interaction rewiring in the community. This study suggests that the conservation of mutualisms, especially those considered keystone, could be essential for long‐term preservation of natural communities under current and future impacts of global change.
Revisiting the virulence hallmarks of Pseudomonas aeruginosa: a chronicle through the perspective of quorum sensing
Authors: Chadha Jatin , Harjai Kusum , Chhibber Sanjay 
Published: September 2021

SummaryPseudomonas aeruginosa is an opportunistic pathogen and the leading cause of mortality among immunocompromised patients in clinical setups. The hallmarks of virulence in P. aeruginosa encompass six biologically competent attributes that cumulatively drive disease progression in a multistep manner. These multifaceted hallmarks lay the principal foundation for rationalizing the complexities of pseudomonal infections. They include factors for host colonization and bacterial motility, biofilm formation, production of destructive enzymes, toxic secondary metabolites, iron‐chelating siderophores and toxins. This arsenal of virulence hallmarks is fostered and stringently regulated by the bacterial signalling system called quorum sensing (QS). The central regulatory functions of QS in controlling the timely expression of these virulence hallmarks for adaptation and survival drive the disease outcome. This review describes the intricate mechanisms of QS in P. aeruginosa and its role in shaping bacterial responses, boosting bacterial fitness. We summarize the virulence hallmarks of P. aeruginosa, relating them with the QS circuitry in clinical infections. We also examine the role of QS in the development of drug resistance and propose a novel antivirulence therapy to combat P. aeruginosa infections. This can prove to be a next‐generation therapy that may eventually become refractory to the use of conventional antimicrobial treatments.
Man Versus Machine: Complex Estimates and Auditor Reliance on Artificial Intelligence

Published: September 2021

ABSTRACTAudit firms are investing billions of dollars to develop artificial intelligence (AI) systems that will help auditors execute challenging tasks (e.g., evaluating complex estimates). Although firms assume AI will enhance audit quality, a growing body of research documents that individuals often exhibit “algorithm aversion”—the tendency to discount computer‐based advice more heavily than human advice, although the advice is identical otherwise. Therefore, we conduct an experiment to examine how algorithm aversion manifests in auditor judgments. Consistent with theory, we find that auditors receiving contradictory evidence from their firm's AI system (instead of a human specialist) propose smaller adjustments to management's complex estimates, particularly when management develops their estimates using relatively objective (vs. subjective) inputs. Our findings suggest auditor susceptibility to algorithm aversion could prove costly for the profession and financial statements users.

AbstractIn the present study, fish meal (FM) was replaced by pea (Pisum sativum) protein (PP) in diet for Rainbow trout (Oncorhynchus mykiss) at levels of 0% (PP0), 25% (PP25), 50% (PP50), 75% (PP75) and 100% (PP100), and the effect of dietary PP level on the digestive system tracts and liver was investigated by micromorphological and histopathological evaluations. Morphometric measurements (mm 100g fish−1) of the liver width and stomach length in rainbow trout were found to be significantly larger (p <0.05) in fish with high‐level pea protein as the main protein source (PP75, PP100) compared to the low‐level PP replacement group (PP25). No significant differences were found in morphometric measurements for pyloric caecum and intestines among treatment groups, whereas the number of the caecum of fish fed the PP25 diets significantly increased over the control (PP0) (p<0.05). In the histological examination of the liver, mild hydropic and vacuolar degeneration was observed in all experimental groups except PP0 and PP25. The measurements of pyloric caecum fold height, enterocyte length and width of tunica muscularis of the high‐level pea protein groups of PP75 and PP100 were significantly higher (p <0.05) compared to the control group. In conclusion, 25% substitution of PP can be suggested for FM in trout diets, because the findings of the present study provided evidence that the digestive system improved by increasing the number of pyloric caecum at this replacement level.

AbstractKidney diseases are the most common illness for cats with a prevalence seven times higher than in dogs. Metanephros is the last of three renal systems to be formed during the embryonic period, which then becomes the permanent kidney. The current work aimed to analyse the morphology and to quantify the structures present in the development of metanephros from domestic cat (Felis catus) embryos and foetuses. For this purpose, the evaluation of the biometric parameters of metanephros from cat embryos and foetuses was performed in addition to the quantification of renal corpuscles and volume of cortical and medullary layers by stereological analysis. The evaluated biometric parameters were weight, width, height, thickness and volume. The values of the measured biometric parameters increased throughout the gestational stages. The quantity of renal corpuscles gradually increased following the embryo‐foetal development, mainly during the middle of the gestational stage. It was during this phase that morphologically, a complete corticomedullary division was observed. Although the difference in the quantity of renal corpuscles between the middle and the end of the gestational stages was not statistically significant, there was an increase in the volume of the medullary layer and a decrease in the volume of the cortical layer between these two stages. These findings suggest that the metanephros presents a progressive growth with the renal corpuscles following this development until the middle of the gestational stage. Starting from this phase, the differentiation of the corticomedullary layers can be seen with a significant increase in the medullary layer.
Breakage, bias and the archaeological surface record: Assessing the quantification problem in archaeological field survey
Authors: Waagen Jitte 
Published: September 2021

AbstractIn the practice of archaeological field survey there is a manifest importance for densities, that is, an abundance of artifacts, often relying on simple counts of objects. However, a well‐known issue is variable breakage of pottery that can cause biases in quantitative analysis. Although such issues are generally acknowledged, a direct assessment of breakage and the resulting biases is lacking in research. This paper explores the pros and cons of quantification methods of surface collections in terms of counts or weights, and demonstrates the importance of analysing weight and breakage as part of an integrative approach.
Is it possible to improve social workers’ program planning capability through organizational learning strategy?
Authors: Kwon Sunae 
Published: September 2021

AbstractThis study investigates the applicability of organizational learning in non‐profit human service organizations for the management of outcome‐based programs. The focus of this study was the organizational learning level of J Agency and the enhancement of outcome‐based program planning capacity through organizational learning. The organizational learning conducted at J Agency consisted of training and consulting sessions to establish an outcome‐based program management system by enhancing the capacity level of social workers. The result of this study shows the organizational learning level of J Agency being lower than other corporations or public organizations, but the program planning capacity through education and consulting to have enhanced positively. Social workers acquired program planning, management, and evaluation knowledge through the learning strategy of training and consulting, and shared and spread it at the team and organizational level. This organizational learning strategy contributed to improving the program planning capacity of social workers, and it can be confirmed that it is useful as an organizational management strategy of non‐profit human service organizations.

AbstractThe presence of intricate carbon skeletons in natural compounds enhances their bioactivity spectrum with unique modes of action at several targets in various dreadful diseases like cancer. The present study was designed to purify the molecules from Thymus linearis and elucidate their antiproliferative activity. The compounds were isolated from the active methanolic extract of Thymus linearis through column chromatography and characterized by various spectroscopic techniques. Antiproliferative activity of isolated compounds was evaluated using MTT assay on cancer and normal cell lines. Mechanism of cell death was elucidated using flow cytometric, microscopic, and Western blot analysis. Four compounds, Sitosterol, Chrysin, 3β‐hydroxylup‐12‐en‐28‐oic acid (3BH), and β‐Sitosterol glycoside, were isolated. Among these, 3BH was most potent antiproliferative agent across all cell lines under study, HCT‐116 being the most affected one. 3BH was demonstrated to downregulate PI3Ksubunits (p110α and p85α), downstream pAktSer473 and prompted G1 phase cell cycle arrest. The cell cycle CDK inhibitor p27 and p21 were upregulated with simultaneous downregulation of cyclin D1 and cyclin E in HCT‐116 cells. This was accompanied by apoptosis, as depicted by decrease in Bcl‐2/Bax ratio, with increase in active caspases‐3 and caspase‐9, cleavage of PARP‐1, the generation of reactive oxygen species (ROS), and the loss of mitochondrial membrane potential. The findings established that 3BH induced cell death in HCT‐116 cells by modulating PI3K/Akt signaling axis, impeding cell cycle, and instigating apoptosis.

AbstractObjectivesInformation on the association between edentulism and chronic medical conditions in developing countries is lacking. We investigated such information among adults aged ≥45 years in China.MethodsA national longitudinal data set from the China Health and Retirement Longitudinal Study (CHARLS) 2011‐2018 was analysed. A multilevel logistic regression model was applied to analyse the association between edentulism and select chronic diseases.ResultsThere were 74 240 Chinese adults aged ≥45 years in this study. The prevalence of self‐reported edentulism was 8.8% in 2011 and had increased to 16.4% by 2018.ConclusionEdentulism was a factor associated with a higher risk of various self‐reported chronic diseases among adults aged ≥45 years in China. Edentulism is one of the comorbidities among ageing people with chronic conditions. Preventive public health policy should consider controlling shared risk factors at an earlier age.

AbstractBackgroundSolid‐organ transplant (SOT) recipients with coronavirus disease 2019 (COVID‐19) have higher risk of adverse outcomes compared to the general population. Whether hospitalized SOT recipients with COVID‐19 are at higher risk of mortality than SOT recipients hospitalized for other causes, including non‐COVID‐19 pneumonia, remains unclear.MethodsWe used logistic regression to compare outcomes of SOT recipients hospitalized with COVID‐19 to non‐COVID‐19 related admissions and with non‐COVID‐19 pneumonia.ResultsOf 17,012 hospitalized SOT recipients, 1682 had COVID‐19. Those with COVID‐19 had higher odds of ICU admission (adjusted odds ratio [aOR] 2.12 [95%CI: 1.88–2.39]) and mechanical ventilation (aOR 3.75 [95%CI: 3.24–4.33]). COVID‐19 was associated with higher odds of in‐hospital death, which was more pronounced earlier in the pandemic (aOR 9.74 [95%CI: 7.08–13.39] for April/May vs. aOR 7.08 [95%CI: 5.62–8.93] for June through November 2020; P‐interaction = .03). Compared to SOT recipients hospitalized with non‐COVID‐19 pneumonia, odds of in‐hospital death were higher in SOT recipients with COVID‐19 (aOR 2.44 [95% CI: 1.90–3.13]), regardless of time of hospitalization (P‐interaction > .40).ConclusionsIn this large cohort of SOT recipients, hospitalization with COVID‐19 was associated with higher odds of complications and in‐hospital mortality than non‐COVID‐19 related admissions, and 2.5‐fold higher odds of in‐hospital mortality, compared to SOT recipients with non‐COVID‐19 pneumonia.
