Effects of a magnetic field on double-diffusive convection of a nanofluid in a cavity saturated by wavy layers of porous media: ISPH analysis
Authors: Aly Abdelraheem M. , Alsedais Noura , Oztop Hakan F. 
Published: July 2021

PurposeThe purpose of this study is to use the incompressible smoothed particle hydrodynamics method to examine the influences of a magnetic field on the double-diffusive convection caused by a rotating circular cylinder with paddles within a square cavity filled by a nanofluid.Design/methodology/approachThe cavity is saturated by two wavy layers of non-Darcy porous media with a variable amplitude parameter. The embedded circular cylinder with paddles carrying T_h and C_h is rotating around the cavity center by a uniform circular velocity.FindingsThe lineaments of nanofluid velocity and convective flow, as well as the mean of Nusselt and Sherwood numbers, are represented below the variations on the frequency parameter, amplitude parameter of the wavy porous layers, Darcy parameter, nanoparticles parameter, Hartmann number and Ryleigh number. The performed simulations showed the role of paddles mounted on circular cylinders for enhancing the transmission of heat and mass within a cavity. The wavy porous layers at the lower Darcy parameter are playing as a blockage for the nanofluid flow within the porous area. Increasing the concentration of the nanoparticles to 6% reduces the maximum flow speed by 8.97% and maximum streamlines |ψ|maxby 10.76%. Increasing Hartmann number to 100 reduces the maximum flow speed by 65.83% and |ψ|maxby 75.54%.Originality/valueThe novelty of this work is to examine the effects of an inclined magnetic field and rotating novel shape of a circular cylinder with paddles on the transmission of heat/mass in the interior of a nanofluid-filled cavity saturated by undulating porous medium layers.

Authors: Raut Umesh K. , Vishwamitra L.K. 
Published: July 2021

Purpose
Software-define vehicular networks (SDVN) assure the direct programmability for controlling the vehicles with improved accuracy and flexibility. In this research, the resource allocation strategy is focused on which the seek-and-destroy algorithm is implemented in the controller in such a way that an effective allocation of the resources is done based on the multi-objective function.

Design/methodology/approach
The purpose of this study is focuses on the resource allocation algorithm for the SDVN with the security analysis to analyse the effect of the attacks in the network. The genuine nodes in the network are granted access to the communication in the network, for which the factors such as trust, throughput, delay and packet delivery ratio are used and the algorithm used is Seek-and-Destroy optimization. Moreover, the optimal resource allocation is done using the same optimization in such a way that the network lifetime is extended.

Findings
The security analysis is undergoing in the research using the simulation of the attackers such as selective forwarding attacks, replay attacks, Sybil attacks and wormhole attacks that reveal that the replay attacks and the Sybil attacks are dangerous attacks and in future, there is a requirement for the security model, which ensures the protection against these attacks such that the network lifetime is extended for a prolonged communication. The achievement of the proposed method in the absence of the attacks is 84.8513% for the remaining nodal energy, 95.0535% for packet delivery ratio (PDR), 279.258 ms for transmission delay and 28.9572 kbps for throughput.

Originality/value
The seek-and-destroy algorithm is one of the swarm intelligence-based optimization designed based on the characteristics of the scroungers and defenders, which is completely novel in the area of optimizations. The diversification and intensification of the algorithm are perfectly balanced, leading to good convergence rates.

Title redacted: the impact of negative online review censorship
Authors: Stevens Jennifer L. , Esmark Jones Carol L. , Breazeale Mike 
Published: July 2021

Purpose
Consumers are increasingly using review sites to exchange product information, whereas companies attempt to maintain control of brand-related communications. One method marketers may take to retain control is to remove negative opinions about the brand. This paper aims to examine the impact on consumer’s brand perceptions when negative reviews are censored.

Design/methodology/approach
Two experimental studies were conducted to assess whether censorship of a negative online review, in the form of removal by the company, weakens brand relationship quality (BRQ) dimensions.

Findings
The results show that censoring negative online reviews has a damaging effect on BRQ. Additionally, the findings indicate that a brand may not be able to increase BRQ when a negative review has been posted, however strategic measures can be taken to diminish the potentially harmful impact.

Originality/value
As many brands still do not adequately understand how to handle negative online reviews, this research offers valuable implications in furthering the examination of negative electronic word-of-mouth and ways to diminish its harmful effects. Additionally, while substantial research focuses on the positive consequences of brand relationships, this research answers calls to examine the negative impacts to BRQ.

How do internet memes affect brand image?
Authors: Teng Hsuju , Lo Chi-Feng , Lee Hsin-Hui 
Published: July 2021

PurposeThis study aims to investigate how Internet memes affect brand image.Design/methodology/approachThe authors first used the Delphi method to refine Internet memes' constructs and dimensions and developed a scale for Internet memes. Second, the authors used a questionnaire to collect data from 348 valid Internet consumers.FindingsThe authors proposed four significant characteristics of Internet memes: humour, high positive emotional intensity, brand interactions and prestige, and high spreadability to prompt consumers to remake, share and spread memes. The study results indicate that Internet memes positively influence the brand image. However, not all meme characteristics were correlated with the brand image; only brand prestige, interaction and humour enhanced brand image.Originality/valueFor scholars in online marketing communication research, this study shifts the current paradigm of brand-generated and customer-passive to user-generated and customer-active. It also addresses the importance of pandemic effects of Internet memes on brand image. To be specific, this study presents the important symbolic values that Internet memes need to include to affect consumers' behaviour in response to perceived brand image by applying both mind infection and symbolic value perspectives. Finally, this study redefines the dimensions and measurements of Internet memes to address the lack of consensus and concrete scales regarding meme transmission characteristics and extending into online marketing communication strategies.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/OIR-11-2019-0364
Early Alternatives to Dutch Descriptive Perception Verb Constructions: A Comparison of Two Bible Translations1
Authors: Poortvliet Marjolein 
Published: July 2021

AbstractCopular constructions (i.e. Subject‐Verb‐Predicative adjective) containing the Dutch descriptive perception verbseruitzien‘look’,klinken‘sound’,voelen‘feel’,ruiken‘smell’ andsmaken‘taste’ (e.g.Zij klinkt blij) emerged throughout Middle Dutch and Early Modern Dutch. It is surprising, then, that no descriptive perception verb constructions are found in the Dutch Bible translation from 1637, even though seventy instances are found in the translation from 2004. This article looks into what alternative strategies are used in the 1637 translation instead of the descriptive perception verb constructions in the 2004 translation. It is found that there are four patterns: the use of a copular construction withzijn‘be’ orschijnen‘seem’, the use of the constructionX's appearance is Y, the use of a construction with a cognitive perception verb, and, lastly, the use of a parenthetical construction. The use of these alternative constructions instead of descriptive perception verb constructions in the 1637 Bible translation can be explained by the fact that the 1637 translation (1) was aimed to reflect the traditional Greek and Hebrew sources (accounting for ≈65% of the alternative constructions found); and (2) still followed (archaic) Middle Dutch grammar.
Crisis management as practice in small‐ and medium‐sized enterprises during the first period of COVID‐19
Authors: Fasth Jonas , Elliot Viktor , Styhre Alexander 
Published: July 2021

AbstractThis article draws attention to the social context and working methods in crisis management. Based on 1000 interviews with business leaders in Swedish small‐ and medium‐sized enterprises (SMEs), we analyze crisis management in practice and ask: What social contexts do business leaders use in crisis management, and what working methods do they rely on? Most companies in this study do not have any form of crisis group; rather, they deal with issues reactively as they occur. Few of the companies work continuously with a crisis plan and only slightly more than half of those that have crisis plans report that it has been helpful in dealing with the COVID‐19 situation. The study concludes that Swedish SMEs seem reliant upon a process that has an emerging nature whereby decisions are largely based on gut feeling. However, the companies in our sample that experienced a significant revenue decline due to the COVID‐19 situation report that they employ a more centralized and deductive approach with reports and documents as a basis for their work. The study contributes to a developed understanding of how crisis management works in practice.
Cold acclimation increases Asian citrus psyllid Diaphorina citri (Hemiptera: Liviidae) survival during exposure to freezing temperatures
Authors: Martini Xavier , Malfa Kathi , Stockton Dara , Rivera Monique J. 
Published: July 2021

AbstractThe Asian citrus psyllid, Diaphorina citri, is the vector of the pathogenic bacteria that causes Huanglongbing, the most devasting disease affecting citrus worldwide. As cultivation of citrus tends to expand northward, the tolerance of psyllids to freezing temperatures needs to be investigated. While mortality of D. citri to cold temperature has been previously studied, much less is known regarding the acclimation potential of psyllids to cold temperatures. We first evaluated cold resistance of D. citri depending on color morph and sex. Subsequently, we compared mortality of D. citri at −4 °C for 10 hours between unacclimated psyllids, psyllids that were gradually acclimated to cold over 1 or 2 weeks, and psyllids intermittently acclimated also for 1 or 2 weeks. We did not find major differences in cold resistance between color morphs and sex. We found that after 1 week of gradual acclimation, the survival of psyllids at −4 °C increased to 86%, compared to 20% in the control group. Survival did not increase after the second week of gradual acclimation. Although intermittent acclimation improved survival compared to the control group, it was less effective than gradual acclimation with a survival at 30% and 70% after 1 and 2 weeks of acclimation, respectively, although this difference with gradual acclimation was not significant at week 2. These data show that gradual cold acclimation allows D. citri to survive brief periods below freezing. It may serve as a mechanism responsible for increasing northern establishment of this pest.
Analysis on the relationship between winter precipitation and the annual variation of horse stomach fly community in arid desert steppe, Northwest China (2007–2019)

Published: July 2021

AbstractGasterophilus spp. have been found to be widespread in reintroduced Przewalski's horses in the Kalamaili Nature Reserve (Northwest China). However, data on the annual variation in Gasterophilus infections are lacking. To analyze the epidemiological features and determine the cause of the annual variation in Gasterophilus infections, we treated 110 Przewalski's horses with ivermectin and collected Gasterophilus larvae from fecal samples each winter from 2007 to 2019. All 110 Przewalski's horses studied were found to be infected by Gasterophilus spp., and a total of 141 379 larvae were collected. Six species of Gasterophilus were identified with the following prevalence: G. pecorum (100%), G. nasalis (96.36%), G. nigricornis (94.55%), G. haemorrhoidalis (56.36%), G. intestinalis (59.09%), and G. inermis (3.64%). The mean infection intensity of Gasterophilus spp. larvae in Przewalski's horses was 1285 ± 653. G. pecorum (92.96% ± 6.71%) was the most abundant species. The intensity of Gasterophilus spp. (r = –0.561, P < 0.046) was significantly correlated with winter precipitation. Our findings confirmed that, in the Kalamaili Nature Reserve, gasterophilosis is a severe parasitic disease in Przewalski's horses. Winter precipitation at the beginning of the year can indirectly affect the intensity and composition of Gasterophilus spp. in Przewalski's horses at the end of the year. Therefore, the water‐related ecological regulation should be carried out to help reduce the parasite infection of Przewalski's horses.

AbstractBackgroundS‐1 and pemetrexed (PEM) are key treatments for non‐small cell lung cancer (NSCLC). However, the mechanism of anticancer activity of S‐1 and PEM is similar. Cross‐resistance between S‐1 and PEM is of concern. This exploratory study was designed to evaluate the treatment effect of S‐1 following PEM‐containing treatment.MethodsThis retrospective study included patients with advanced (c‐stage III or IV, UICC seventh edition) or recurrent NSCLC who received S‐1 monotherapy following the failure of previous PEM‐containing chemotherapy at six hospitals in Japan. The primary endpoint of the study was the overall response rate (ORR). The secondary endpoint was the disease control rate (DCR), time to treatment failure (TTF), progression‐free survival (PFS), and overall survival (OS).ResultsA total of 53 NSCLC patients met the criteria for inclusion in the study. Forty‐six patients had adenocarcinoma (88.7%) and no patients had squamous cell carcinoma. Thirty‐one patients (58.5%) received the standard S‐1 regimen and 18 patients (34.0%) received the modified S‐1 regimen. ORR was 1.9% (95% confidence interval [CI]: 0.00%–10.1%). Median TTF, PFS, and OS were 65, 84, and 385 days, respectively.ConclusionsAlthough there were several limitations in this study, the ORR of S‐1 after PEM in patients with nonsquamous (non‐SQ) NSCLC was low compared to the historical control. One of the options in the future might be to avoid S‐1 treatment in PEM‐treated patients who need tumor shrinkage.

Published: July 2021

SummarySelf‐reported postoperative functional recovery is an important patient‐centred outcome that is rarely measured or considered in research and decision‐making. We conducted a secondary analysis of the measurement of exercise tolerance before surgery (METS) study for associations of peri‐operative variables with functional decline after major non‐cardiac surgery. Patients who were at least 40 years old, had or were at risk of, coronary artery disease and who were scheduled for non‐cardiac surgery were recruited. Primary outcome was a reduction in mobility, self‐care or ability to conduct usual activities (EuroQol 5 dimension) from before surgery to 30 days and 1 year after surgery. A decline in at least one function was reported by 523/1309 (40%) participants at 30 days and 320/1309 (24%) participants at 1 year. Participants who reported higher pre‐operative Duke Activity Status indices more often reported functional decline 30 days after surgery and less often reported functional decline 1 year after surgery. The odds ratios (95%CI) of functional decline 30 days and 1 year after surgery with moderate or severe postoperative complications were 1.46 (1.02–2.09), p = 0.037 and 1.44 (0.98–2.13), p = 0.066. Discrimination of participants who reported functional decline 30 days and 1 year after surgery were poor (c‐statistic 0.61 and 0.63, respectively). In summary, one quarter of participants reported functional decline up to one postoperative year.
Continuous positive airway pressure treatment may negatively affect auditory maturation in preterm infants

Published: July 2021

AbstractAimNasal continuous positive airway pressure (CPAP) devices generate loud noise, which might harm auditory function and maturation. The function of auditory pathways can be examined by using brainstem auditory evoked potential (BAEP) and brainstem audiometry (BA) recordings. Our objective was to study whether CPAP treatment during the neonatal period is associated with abnormalities in BAEP and BA recordings.MethodsIncluded in this retrospective study were preterm infants (birth weight ≤1500 g and/or gestational age ≤32 weeks) born between 2002 and 2006 with a comprehensive clinical background and follow‐up data, including the duration of CPAP treatment (n = 162). BAEP and BA were recorded near the mean corrected age of one month. The following variables from BAEP and BA examinations were analysed: latencies of BAEP components I, III, V, interpeak intervals (IPI) I‐V, I‐III, III‐V (ms), amplitude I and V (µV), amplitude ratio I/V and BA thresholds.ResultsIn the adjusted analysis, a longer CPAP treatment leads to longer latencies of BAEP component III (p = 0.01) and V (p = 0.02) in the right ear.ConclusionCPAP treatment may impair the auditory maturation and processing mediated via the dominant right ear. The hearing and neurodevelopment of the children who are treated with CPAP should be followed.
