Authors: Wang Jerred Junqi , Qian Tyreal Yizhou , Li Bo , Mastromartino Brandon 
Published: January 2022

PurposeBuilt upon the balance theory and schema theory, this study examined the impact of sponsors' intangible attributes, including consumer-based brand equity (CBBE) and brand-event image fit (BEIF), on consumer responses to emerging local events (ELEs), as well as major boundary conditions of this mechanism.Design/methodology/approachTheoretical hypotheses were tested using multivariate analysis of covariance and structural equation modeling with the data from two experiments: the experiment in the pilot study was used to calibrate sponsor stimuli, and the experiment in the main study was designed to assess consumer responses to different sponsor-event combinations.FindingsResults of this experimental study illustrated the dominant role of CBBE in influencing individuals' perceived event value and intention to participate in the context of ELEs and revealed the noticeable but limited moderating effects of BEIF and sport identification.Originality/valueThis study highlighted the importance of sponsorship in the marketing communications of ELEs and suggested prioritizing the overall attributes of sponsors in the sponsor-selection. This study also called for more research attention directed toward the intangible benefits that sporting events could receive from sponsorship deals.

Published: January 2022

Purpose
The purpose of this study is to explore the virtual space of the library and how it is part of the library building and many spaces offered. It inspects as well the work of the International Federation of Library Associations and Institutions’ section related to library buildings and equipment libraries can play if they are able to provide remote users education, which can help in fighting illiteracy and promote digital literacy.

Design/methodology/approach
The study adopted a structuralist approach from linguistics, sociology and anthropology to decorticate the concept of space. It favoured the literature review method, which was the most adequate approach for multidisciplinary results.

Findings
The study results indicate that the library virtual space became equally important as its physical spaces for our modern world and development. The significance of the virtual spaces is similar nowadays to the physical spaces of libraries as they allow for social integration and self-recognition.

Originality/value
The value of this study is uniquely exhaustive, as it highlights the value and significance of the library virtual space in the contemporary world, in comparison with the library physical spaces.

Published: January 2022

PurposeThis study aims to explore the effectiveness of the e-learning solutions adopted during the COVID-19 pandemic based on teachers' and students' opinions in Saudi higher education.Design/methodology/approachThis study was performed during the 2021 academic year and involved a survey approach to analyze the effectiveness of Saudi e-learning solutions adopted during the COVID-19 pandemic. Subjective opinions were collected from a sample of 106 teachers and 1,196 students.FindingsThe teachers disagreed that online courses provide students with multiple opportunities to track their learning progress with timely feedback, with an arithmetic mean of 2.566 and a standard deviation of 1.627. Moreover, the students disagreed that the use of multimedia facilitates the ease of learning and knowledge extraction from online resources, with an arithmetic mean of 2.443 and a standard deviation of 1.633. Generally, the study implies that today during the COVID-19 pandemic, we need to exploit the power of multimedia tools to bring out knowledge from online learning resources such as images, animations, simulations, video and hypermedia. Based on the results, we need to concentrate on exploiting the power of hypertext systems used in flexible online instruction to enable flexible thinking for online students. Therefore, the e-learning process must favor cognitive flexibility and foster knowledge acquisition for students in the context of e-learning during the COVID-19 pandemic.Originality/valueThe findings may be useful in discovering the degree of effectiveness of Saudi e-learning solutions during the spread of the COVID-19 pandemic.

Authors: N. Saravanan , B. Navin Kumar , G. Bharathiraja , R. Pandiyarajan 
Published: January 2022

Purpose
This paper aims to investigate the resultant optimal ultimate tensile strength, elongation, flexural strength and modulus, compression strength and impact strength of fabricated alkali-treated Lagenaria siceraria fiber (LSF)-reinforced polymer matrix composite by optimizing input factors and microstructural characterization by influencing fiber length, fiber concentration and treatment condition of LSF.

Design/methodology/approach
The fabrication of LSF-reinforced composite specimens involved surface treatment followed by custom experimental design using a simple hand layup process. The wear analysis was performed by a multi-tribotester TR25 machine, and the developed model was validated by using statistical software Design Expert V.8 and analysis of variance (ANOVA). The surface morphology of the sample was also analyzed by field emission scanning electron microscopy.

Findings
The alkali treatment for LSFs had reduced the hemicellulose, and enhanced mechanical performance was observed for 30 wt.% concentration of L. siceraria in epoxy resin. Thermogravimetric analysis revealed thermal stability up to 245°C; microstructure revealed fiber entanglements in case of longer fiber length and compression strength reduction; and the surface-treated fiber composites exhibited reduced occurrences of defects and enhanced matrix–fiber bonding. Enhanced mechanical performances were observed, namely, ultimate tensile strength of 17.072 MPa, elongation of 1.847%, flexural strength of 50.4 MPa, flexural modulus of 3,376.31 GPa, compression strength of 52.154 MPa and impact strength of 0.53 joules.

Originality/value
The novel approach of optimizing and characterizing alkali surface-treated LSF-reinforced epoxy matrix composite was explored, varying fiber length and concentrations for specimens by empirical relations and experimental design to obtain optimal performance validated by ANOVA. Enhanced properties were obtained for: 7 mm fiber length and 30 wt.% concentration of fiber in the composite for alkali-treated fiber.
A reproducible and sensitive method for generating high‐quality transcriptomes from single whitefly salivary glands and other low‐input tissues
Authors: Gebiola Marco , Le Brandon H. , Mauck Kerry E. 
Published: January 2022

AbstractTranscriptomic studies are an important tool for understanding the molecular pathways underlying host plant use by agricultural pests, including vectors of damaging plant pathogens. Thus far, bulk RNA‐Seq has been the main approach for non‐model insects. This method relies on pooling large numbers of whole organisms or hundreds of individually dissected organs. The latter approach is logistically challenging, may introduce artifacts of handling and storage, and is not compatible with biological replication. Here, we tested an approach to generate transcriptomes of individual salivary glands and other low‐input body tissues from whiteflies (Bemisia tabaciMEAM1), which are major vectors of plant viruses. By comparing our outputs to published bulk RNA‐Seq datasets for whole whitefly bodies and pools of salivary glands, we demonstrate that this approach recovers similar numbers of transcripts relative to bulk RNA‐Seq in a tissue‐specific manner, and for some metrics, exceeds performance of bulk tissue RNA‐Seq. Libraries generated from individual salivary glands also yielded additional novel transcripts not identified in pooled salivary gland datasets, and had hundreds of enriched transcripts when compared with whole head tissues. Overall, our study demonstrates that it is feasible to produce high quality, replicated transcriptomes of whitefly salivary glands and other low‐input tissues. We anticipate that our approach will expand hypothesis‐driven research on salivary glands of whiteflies and other Hemiptera, thus enabling novel control strategies to disrupt feeding and virus transmission.

Published: January 2022

AbstractThe effect of carbon dioxide‐argon radio frequency cold plasma treatment on the in vitro digestion and structural characteristics of granular and non‐granular waxy maize, potato, and rice starches was investigated in this study. The effect on the fine structure of waxy potato was very minimal after plasma treatment irrespective of their granular or non‐granular form. The short chain length (SCL) of waxy maize and rice (granular and non‐granular) starches was reduced leading to subsequent increases in the long chain length (LCL). In vitro digestibility studies showed that cold plasma treatment enhanced (p < 0.05) the amount of slowly digestible starches (5.62%; 10.24%) and resistant starches (0.28%; 85.66%) in non‐granular waxy maize (WMS NG) and granular waxy potato starches (WPS G), respectively. The amount of rapidly digestible starches increased in granular waxy maize starch (WMS G) (85.08%) but was unaffected in non‐granular waxy rice (WRS NG), WPS G, and non‐granular waxy potato starches after plasma treatment. FTIR‐ATR data confirmed the ability of cold plasma to induce cross‐linking in waxy starches specifically in WMS NG, WRS G, WRS NG, and WPS G. Overall, the unit and internal chain structure of the waxy starches were mostly unaffected by radio frequency plasma treatment. Cross‐linking served as the dominant mechanism by which plasma altered the structure and digestibility of these starches.Practical ApplicationCold plasma technology has been suggested as a green technique for starch modification. More research is, however, needed to facilitate the industrial scale up of this technology. In this study, we utilized a carbon dioxide‐argon radio frequency cold plasma to modify waxy maize, rice and potato starches. Cold plasma treatment resulted in starches that were resistant to digestion and were highly cross‐linked. The cross‐linking would give the starches the ability to possibly withstand the high temperatures and shear that can be applied during industrial processing.

AbstractAimsTo investigate whether e‐cigarette and cigarette susceptibility predict e‐cigarette and cigarette use among American youth 1 year later.Design and SettingLongitudinal data from the Population Assessment of Tobacco and Health (PATH) Study—a four‐stage, stratified probability cohort study of youth (12–17 years old) sampled from the United States civilian, non‐institutionalized population. Multivariable logistic regression was used to estimate the association between initial product‐specific susceptibility and subsequent cigarette smoking and e‐cigarette use while controlling for sociodemographic characteristics, exposure to nicotine users, and behavioral risk factors.ParticipantsThe sample included 8841 adolescent never nicotine users at initial survey who participated in both wave 4 (2016–2017) and wave 4.5 (2017–2018) of PATH.MeasurementsWe measured cigarette and e‐cigarette susceptibility (defined as a lack of a firm commitment to not use cigarettes or e‐cigarettes) among never nicotine users at baseline (wave 4) as well as cigarette and e‐cigarette use at 12‐month follow‐up (wave 4.5).FindingsYouth e‐cigarette susceptibility was statistically significantly (P < 0.05) associated with e‐cigarette use 1 year later, for both past 12‐month (adjusted odds ratio [aOR], 2.99; 95% CI, 2.29–3.90) and past 30‐day e‐cigarette use (aOR, 2.73; 95% CI, 1.78–4.16), but not with cigarette smoking (aOR, 1.05; 95% CI, 0.64–1.73 for past 12‐month smoking and aOR, 0.65; 95% CI, 0.29–1.45 for past 30‐day smoking. Smoking susceptibility predicted subsequent smoking in the past 12 months (aOR, 1.82; 95% CI, 1.09–3.03) and past 30 days (aOR, 3.32; 95% CI (1.33–8.29), but not e‐cigarette use in the past 12 months (aOR, 0.96; 95% CI, 0.77–1.19) or past 30 days (aOR, 1.11; 95% CI, 0.82–1.51).ConclusionE‐cigarette and cigarette susceptibility measures appear to predict product‐specific use among youth 1 year later.

AbstractAimsTo examine the association of alcohol consumption patterns with growth differentiation factor 15 (GDF‐15) in older drinkers, separately among individuals with cardiovascular disease (CVD)/diabetes and those without them, as GDF‐15 is a strong biomarker of chronic disease burden.DesignCross‐sectional study.SettingPopulation‐based study in Madrid (Spain).ParticipantsA total of 2051 life‐time drinkers aged 65+ years included in the Seniors‐ENRICA‐2 study in 2015–17. Participants’ mean age was 71.4 years and 55.4% were men.MeasurementsAccording to their average life‐time alcohol intake, participants were classified as occasional (≤ 1.43 g/day), low‐risk (men: > 1.43–20 g/day; women: > 1.43–10 g/day), moderate‐risk (men: > 20–40 g/day; women: > 10–20 g/day) and high‐risk drinkers (men: > 40 g/day; women: > 20 g/day; or binge drinkers). We also ascertained wine preference (> 80% of alcohol derived from wine), drinking with meals and adherence to a Mediterranean drinking pattern (MDP) defined as low‐risk drinking, wine preference and one of the following: drinking only with meals; higher adherence to the Mediterranean diet; or any of these.FindingsIn participants without CVD/diabetes, GDF‐15 increased by 0.27% [95% confidence interval (CI) = 0.06%, 0.48%] per 1 g/day increment in alcohol among high‐risk drinkers, but there was no clear evidence of association in those with lower intakes or in the overall group, or across categories of alcohol consumption status. Conversely, among those with CVD/diabetes, GDF‐15 rose by 0.19% (95% CI = 0.05%, 0.33%) per 1 g/day increment in the overall group and GDF‐15 was 26.89% (95% CI = 12.93%, 42.58%) higher in high‐risk versus low‐risk drinkers. Drinking with meals did not appear to be related to GDF‐15, but among those without CVD/diabetes, wine preference and adherence to the MDP were associated with lower GDF‐15, especially when combined with high adherence to the Mediterranean diet.ConclusionsAmong older life‐time drinkers in Madrid, Spain, high‐risk drinking was positively associated with growth differentiation factor 15 (a biomarker of chronic disease burden). There was inconclusive evidence of a beneficial association for low‐risk consumption.

Published: January 2022

AbstractAimsTo provide an overview of research literature on ageing and older people who use illicit opioids and stimulants by documenting the conceptual frameworks used and content areas that have been investigated.MethodsWe conducted a scoping review of literature relating to ageing and older people who use illicit stimulants and opioids, defining ‘older’ as 40 years and above. Primary studies, secondary studies and editorials were included. Searches were conducted in PubMed and Embase in July 2020 and March 2021; the Cochrane library was searched in November 2021. Charted data included methodological details, any conceptual frameworks explicitly applied by authors and the content areas that were the focus of the publication. We developed a hierarchy of content areas and mapped this to provide a visual guide to the research area.ResultsOf the 164 publications included in this review, only 16 explicitly applied a conceptual framework. Seven core content areas were identified, with most publications contributing to multiple content areas: acknowledgement of drug use among older people (n = 64), health status (n = 129), health services (n = 109), drug use practices and patterns (n = 84), social environments (n = 74), the criminal legal system (n = 28) and quality of life (n = 15).ConclusionsThe literature regarding older people who use illicit drugs remains under‐theorized. Conceptual frameworks are rarely applied and few have been purposely adapted to this population. Health status and health services access and use are among the most frequently researched topics in this area.

AbstractPurposeTo assess the image quality and delineation value of compressed sensing (CS)‐accelerated 3D T2W turbo‐spin‐echo (TSE) sequence for radiotherapy treatment planning (RTP) of prostate cancer.MethodsAn optimized CS‐accelerated 3D‐T2W‐TSE was determined by volunteer imaging and applied for clinical RTP‐MRI. This optimized CS‐accelerated planning MRI and the standardized adaptive MRI acquired at 1.5T were retrospectively analyzed in 26 prostate cancer patients who were to receive MR‐guided radiotherapy. Signal‐to‐noise ratio (SNR) and relative contrast ratio (CR) were quantitatively assessed. Image quality and artifacts were qualitatively assessed using a five‐point scale rating. Delineation value in the prostate and organs‐at‐risk (OARs) was also rated and compared. Wilcoxon signed‐rank test was used for SNR, relative CR, and rating comparisons. The interobserver rating agreement was evaluated by percent agreement.ResultsSignificantly better SNR and relative CR in the prostate, rectum, bowel, penis, and penile bulb, while significantly worse in the cauda equina, were observed on the planning MRI. Significantly better ratings of image quality and artifacts were given to the planning MRI, with much less Gibbs ringing and reconstruction artifacts. Significantly better delineation value rating was achieved on the planning MRI in the prostate, seminal vesicle, rectum, penis, penile bulb, and testes, while significantly worse in the cauda equina. A strong to almost perfect interobserver rating agreement was obtained.ConclusionThis study suggested that CS acceleration is applicable and valuable in prostate RTP‐MRI. CS‐accelerated 3D‐T2W‐TSE images should benefit the delineation of prostate and many OARs.

AbstractAfrican savannah elephants (Loxodonta africana) can have detrimental impacts on trees; studies exploring elephant impact within small, fenced reserves, have lacked focus in determining elephant high‐use areas, the direct effect of fence line and tree recovery. The aim of this study is to assess whether elephants cause significant impact on trees in the small‐fenced Karongwe Private Game Reserve (KPGR) and to determine the levels of tree recovery. Trees ≥5 m in height were surveyed (n = 634 trees). Elephant location data were used to identify high‐ and low‐use areas. Five species accounted for 80% of the records; these were used for further analysis. Trees in high‐use areas were significantly less likely to show signs of debarking and push over. Tall trees were significantly more likely to be impacted by elephants, being associated with heightened risks of debarking and branches being broken but lower risks of being pushed over. Trees close to the fence line were not more impacted than trees near the centre of the reserve. The level of use, distance to the fence and tree height were not significant predictors of tree recovery indicators. Future mitigation efforts should focus on trees with high levels of impact and low levels of recovery.

AbstractBackgroundBeneficial effects of hyaluronic acid (HA)‐based selection of spermatozoa for intracytoplasmic sperm injection (ICSI) are still controversial, and further studies are needed to categorize patients that might benefit from such a method.ObjectiveWe investigated whether HA sperm selection improved ICSI outcome of couples with previous ICSI cycle failure.Materials and methodsIn this retrospective study, we prospectively collected data of (i) Group 1: 96 couples who performed one failed ICSI cycle (“1st procedure,” n = 96) followed by another ICSI cycle (“2nd procedure,” n = 101); ii) Group 2: 87 couples who performed one failed ICSI cycle (n = 87) followed by an HA‐ICSI cycle (n = 104). Differences between procedures and groups were measured by paired and independent statistical tests, respectively. A generalized linear mixed model analyzed the effect of procedure on the outcomes and the interaction between procedures and groups.ResultsInjection of HA‐bound sperm significantly improved cleavage rate with respect to standard ICSI (p = 0.026). No evolutive pregnancies were obtained in the 1st ICSI attempts. The 2nd ICSI cycles resulted in successfully seven pregnancies. In HA‐ICSI cycles, the better quality of embryos with respect to ICSI (p = 0.034) increased the choice of day 5 embryo transfer (p = 0.030), which resulted in successfully 28 pregnancies. No differences were observed in clinical outcomes of the two ICSI procedures in Group 1, while pregnancy and implantation rates were significantly higher in HA‐ICSI with respect to ICSI cycles (p = 0.001, p < 0.0001, respectively). No negative perinatal outcomes were recorded.DiscussionIn couples where previous 1st ICSI failed, selection of HA‐bound spermatozoa significantly improved clinical outcomes with respect to further standard ICSI.ConclusionThis study identified couples with previous ICSI cycles failure as a category of infertile patients that really may benefit from HA sperm selection before ICSI.
