Authors: Morris J. R. , Cawthon D. L. , Spayd S. E. , May R. D. , Bryan D. R.
Published: September 2022

Fruit samples of grape (Vitis labrusca L., cv. Concord) from 6 vineyard locations were collected at 7 to 10-day intervals beginning prior to veraison and continuing through development of 16% soluble solids for a period of 19 years. The 19-year average date for peak bloom in these vineyards was May 19, for 8% soluble solids development was July 27 (69 days from peak bloom), and for 16% soluble solids development was August 23 (96 days from peak bloom). Heat unit summations were more closely related to development of soluble solids than to changes in either titratable acidity or color. Using degree-day accumulations and effective heat unit summations did not prove to be methods superior to use of the number of calendar days for predicting grape maturation. Predictions from 8 to 16% soluble solids development were more accurate than predicting from peak bloom (when 50% of clusters showed bloom). Variations between years and between vineyard locations within a given year prevented accurate predictions from the 3 methods. Other deterrents observed in predicting development of soluble solids included the cultural variables of fruit load and soil moisture.
Foliar Injury and Growth of Tomato Cultivars as Influenced by Ozone Dose and Plant Age1
Authors: Reinert R. A. , Henderson W. R.
Published: September 2022

Six cultures of Lycopersicon esculentum Mill. were exposed to 3 doses of ozone (O3) at 3 ages. Cultivars exposed to O3 at 2 weeks age ranked differently in sensitivity based on foliar injury than cultivars exposed at 4 and 6 weeks. Cultivars were more sensitive to O3 at 4 than at 6 weeks but sensitivity rankings based on foliar injury were similar. The highest O3 dose significantly inhibited the growth of all cultivars, except ‘Heinz 1439’ at 6 weeks. Cultivar rankings based on average percent change in growth from control plants were more similar at 4 and 6 weeks compared with 2 weeks.
Inheritance of Wood Hardiness among Hybrids of Commercial and Wild Asian Peach Genotypes1
Authors: Cain D. W. , Andersen R. L.
Published: September 2022

Seven clones of peach (Prunus persica (L.) Batsch) varying in hardiness, and 5 progenies derived from them were used to study the inheritance of cambium, xylem, and vegetative bud hardiness. Mean progeny cambium and xylem hardiness could be predicted from average parental performance, but vegetative bud hardiness could not. Injury within dates and tissues was highly heritable and environmental variation was very low. Correlations among injury ratings for different tissues, temperatures, and dates were low when based on individual trees indicating poor repeatability of individual genotypes over time. Correlations based on family means were higher. The low correlations based on individual trees indicate that selection based on individual phenotypic performance in a single test might be ineffective.
Seasonal and Diurnal Variations in Abscisic Acid, Water Potential, and Diffusive Resistance in Leaves from Irrigated and Non-irrigated Peach Trees1
Authors: Xiloyannis Cristos , Uriu K. , Martin G. C.
Published: September 2022

Water potential, diffusive resistance, and abscisic acid (ABA) were measured at 10-12 day intervals from May to October in leaves from irrigated and non-irrigated peach (Prunus persica L. cv. Fay Elberta) trees, and measurements were taken at intervals from sunrise to sunset on September 8. Leaf water potential, before sunrise, was between −5 and −8 bars in irrigated trees during the entire season whether drip irrigated at 100% evapotranspiration (ET) or 50% ET. Non-irrigated trees showed a decrease in pre-dawn leaf water potential with time, following a pattern similar to that of decreasing soil moisture. Leaf water potential values taken during the afternoon were not associated with soil moisture and did not reflect the stressed condition of the trees. In non-irrigated trees stomatal resistance at mid-day increased rapidly after mid-summer as leaf water potential decreased. ABA concentration in leaves from irrigated trees ranged from 30 to 80 ng/g fresh wt during the entire season. In non-irrigated trees the ABA concentration increased sharply after mid-summer; this was associated with an increase in leaf diffusive resistance and a decrease in leaf water potential. Diurnal variations in leaf water potential were associated with changes in soil moisture, air temperature, relative humidity, and stomatal resistance. Leaf diffusive resistances were similar for all treatments until 1100 hr after which a notable increase occurred with increasing stress, ultimately leading to stomatal closure. ABA concentrations in leaves from irrigated and non-irrigated trees increased as leaf diffusive resistance increased; however in stressed trees, high levels of ABA in the morning were not associated with closed stomata.
Translocation of 14C-photosynthate, Carbohydrate Content, and Nitrogen Fixation in Phaseolus vulgaris L. during Reproductive Development1
Authors: Waters Luther , Breen Patrick J. , Mack Harry J. , Graham Peter H.
Published: September 2022

Leaves at nodes 4 or 8 of greenhouse grown beans, Phaseolus vulgaris L., cv. Puelba 152, were briefly exposed to 14CO2 at 35, 48, 63, or 70 days after planting. Prior to flowering, over 85% of the recovered 14C-activity translocated in 24 hours from node 4 was in roots, nodules, and lower stem. At flowering, radioactivity translocated to the lower stem decreased but correspondingly increased in nodules. Roots sequestered 45% of translocated-14C throughout the life of the node-4 leaf. About 80% of the 14C-activity exported from node 8 at flowering was in middle and upper stem sections, but during pod-fill over 85% moved into the pods and less than 1% to the nodulated root system. Starch concentration in the lower stem increased continuously from flowering, but in other plant parts declined after early pod-fill. At mid pod-fill, the concentration of soluble sugars in nodules and roots declined and reached a common value in stem sections. Nitrogen (C2H2) fixation decreased rapidly after peaking at early pod-fill. This decline, which was accompanied by loss of lower leaves, occurred in the presence of a high concentration of starch in the stem.
Water Relations and Related Leaf Characteristics of Healthy and Blight Affected Citrus Trees1
Authors: Syvertsen J. P. , Bausher M. G. , Albrigo L. G.
Published: September 2022

Citrus blight or young tree decline, is a wilt-like disease of unknown etiology which is characterized by restricted water movement and an upset in normal zinc distribution patterns. Diurnal leaf and fruit water potentials and leaf stomatal conductances of sweet orange Citrus sinensis (L.) Osbeck leaves on trees in various stages of decline were characterized to determine the progression of this disorder. All blight affected trees, regardless of severity of tree condition, had similar diurnal water relations. Blight affected trees have fewer and smaller leaves, less leaf area per tree, lower stomatal conductances, and lower diurnal transpiration rates than healthy trees. These differences did not result in any apparent changes in specific leaf weight, leaf osmotic potentials or in the critical leaf water deficits at which leaf turgor was lost. At equivalent transpirational fluxes, leaf water potential was much lower in blight affected trees than in healthy trees. Therefore, the water stress symptoms associated with blight are related to increased resistances in the water transport system and are not a result of lost stomatal function or changes in water relations characteristics of leaves that remain on blight affected trees.
Sampling Strategies for Estimates of Cluster Weight, Soluble Solids and Acidity of ‘Concord’ Grapes1
Authors: Wolpert James A. , Howell Gordon S. , Cress Charles E.
Published: September 2022

Variability of cluster weight, soluble solids, and titratable acidity of ‘Concord’ grapes (Vitis labruscana Bailey) was quantified with respect to several fixed and random factors. All 3 measurements were affected by cluster position while only cluster weight and soluble solids were affected by sunlight exposure. Estimates of variance components indicated that the greatest percentage variability was among vines. Variance components were used to examine efficient sampling plans that would detect a specified difference at a selected level of Type I error. Graphs illustrate various schemes of sample allocation which would achieve the desired level of precision.
Drainage Requirements for Sweet Potato at Harvest1
Authors: Akparanta S. E. , Skaggs R. W. , Sanders D. C.
Published: September 2022

Poor drainage resulting in high soil moisture causes wet soil injury in the fleshy roots of sweet potato (Ipomoea batatas (L) Lam). Sweet potato lines with varying resistance to flood damage were grown in a sandy loam and a silt loam soil and subjected to water table drawdown rates of 5, 20, 35 and 100 cm/day for 7 days prior to harvest. Decay increased with time after harvest and decreasing drawdown rate. ‘Julian’ had the longest postharvest keeping quality for the various drainage rates applied and there was no difference in keeping quality between soils. ‘Centennial’ was intermediate, showing wet soil damage with lower drainage rates and the damage was higher on the silt loam than on the sandy loam soil. NC 257 showed high wet soil injury for all drainage rates with greater injury in the finer textured soil. Decay of the roots was greater in 1976 than in 1975 for all genetic sources. pH, titratable acidity and soluble K were well correlated with decay in 1975 but not in 1976.
Growth Responses and Leaf Nutrient Concentrations of ‘Fordhook 242’ Lima Beans as Affected by Fertilizer Treatment and Plant Stand1
Authors: Smith Cyril B.
Published: September 2022

‘Fordhook 242’ lima beans (Phaseolus lunatus L.) were grown in 1973-1974 with 16 fertilizer treatments and 2 plant stands (11 and 16 plants/m) at 0.96 m row width. Soils used were low in P and Mg, medium in K and high in Ca. Banded fertilizer treatments were 28 or 56 kg/ha of N, P, K, and Mg in various combinations, 5 N sources compared at 56-56-0 kg/ha, and 2 commercial fertilizers, 18-46-0 and 8-24-8. With an increase in plant stand from 11 to 16 plants/m of row, vine growth was increased and maturity was delayed but yield of marketable beans was not influenced. Yields were increased an average of 74% by 6 treatments at or close to 56-56-0 kg/ha with and without K when compared to check. N sources, P and K all affected maturity. Urea, (NH4)2SO4, and NH4NO3 resulted in higher yields than Ca(NO3)2 and NaNO3 primarily by hastening maturity. Leaf concentrations of Ca and Mg were enhanced by P and all N sources while leaf K was lowered. Applied K depressed leaf Mg. Thus when both K and Mg were added to NP treatment, Mg leaf concentration was not changed.
A Combined Experimental and Theoretical DFT (B3LYP and CAMB3LYP)
Study on Spectral Features (FT-IR, NMR, and UV-Visible),

Published: September 2022

The pyrazolone subordinate, aminopyrine, has been broken down tentatively and hypothetically
for its vibrational frequencies. The chemical shift values and symphonious vibrational frequencies
as obtained at B3LYP/CAM-B3LYP/6-31G after employing proper scaling techniques appear to
match acceptably with the test perceptions. The hypothetical spectrograms for NMR, FT-IR and UV
spectra of aminopyrine have been likewise developed and contrasted with the trial spectra. Determined
hyperpolarizability (4.531 ×10-30 esu) showed that the particle might have a nonlinear optical
(NLO) component with non-zero qualities. An investigation of hydrogen bonding, utilizing mathematical
and topological boundaries, has additionally been conducted.
Registration between 2D and 3D Ultrasound Images to Track Liver Blood
Vessel Movement
Authors: Masuda Kohji , Shimizu Taichi , Nakazawa Takumi , Edamoto Yoshihiro
Published: September 2022

Background:

For the accurate positioning of surgical tools, conventional intraoperative navigation systems have been developed to recognize the relationship between target positions and the tools. However, since an internal organ is deformed during the operation, registratin between real-time two-dimensional (2D) ultrasound images and three-dimensional (3D) CT or MRI images is not always effective. Therefore, this study developed image registration between 2D and 3D ultrasound images considering deformation for tracking target vessel movement in the liver.

Methods:

3D ultrasound image was obtained in advance with 3D coordinates, including the target vessel. Then real-time 2D images and ultrasound probe position were simultaneously acquired using a 3D position sensor. We applied multiple image resolution registration, where rapid and fine optimizations can be expected in higher and lower levels, respectively. Meanwhile, gradient descent method was adopted for the optimization, which determines the relative arrangements to obtain maximum similarity between 2D and 3D images. We experimentally established resolution level parameters using a phantom before applying it to track liver blood vessel movements in a normal healthy subject.

Results:

Comparing between the 2D images and the registered images, although the approach has some limitations in tracking large displacement, we confirmed that the cross section of the target blood vessel was clearly visualized.

Conclusion:

This method has a potential for an ultrasound therapy targeting blood vessels under natural respiration conditions.
Technology-enabled Behavioral Health Integration Decreases Emergency Department Utilization
Authors: Pardes Adam , Rene Rachelle , Chun Phansy , Cherson Mollie
Published: September 2022

Background:

Behavioral health integration allows for patient-centered care, leads to higher levels of provider-patient engagement, and is key to improving patient outcomes. However, behavioral health integration is administratively burdensome and therefore is often not adopted. Technology presents opportunities to increase care team efficiency and improve patient outcomes. The goal of this study was to retrospectively compare clinical outcomes and emergency department utilization in patients using a technology platform compared to patients receiving treatment as usual.

Methods:

The technology platform, NeuroFlow, was deployed to deliver technology-enabled behavioral health integration in 30 clinics, and 598 electronic health records were analyzed.

Results:

In the six-month period following technology-enabled behavioral health integration implementation, emergency department utilization decreased by 34% in the treatment group (n=259), while increasing by 58% in the treatment as usual group (n=339). Additionally, statistically significant (p < .01) decreases in PHQ-9 (-17.3%) and GAD-7 (-12.4%) scores were only observed in the treatment group.

Conclusion:

Findings from this study support use of a technology-enabled behavioral health tool to decrease emergency department use and highlight the importance of measurement-based care. Future research will be key to enhancing behavioral health technology and integration to further improve patient outcomes and reduce emergency department utilization.
Biofilm Formation Status in ESBL-Producing Bacteria Recovered from
Clinical Specimens of Patients: A Systematic Review and Meta-Analysis
Authors: Karbalaei Mohsen , Keikha Masoud
Published: September 2022

Background:

Recently, the emergence and spread of extended-spectrum beta-lactamase
(ESBL) bacteria have become a global health concern. In addition, the ability to form biofilm due to
less impermeability to antibiotics and the horizontal transformation (conjugation) of genes involved in
antibiotic resistance have exacerbated the concerns. With a comprehensive meta-analysis, this study
evaluated the potential relationship between ESBL and biofilm formation

Methods:

A literature search was performed using global databases, such as PubMed and Scopus, up to
November 2021. We retrieved all relevant documents and selected eligible articles based on inclusion
criteria. Finally, the potential association between the biofilm formation capacity and resistance of
ESBL-producing bacteria was measured with an odds ratio and a 95% confidence interval.

Results:

In the present study, 17 articles, including 2,069 Gram-negative isolates, were considered as
eligible. The prevalence of biofilm formation in all clinical isolates of ESBL and non-ESBL pathogens
was 72.4% (95% CI: 60.7-81.6) and 40.5% (95% CI: 30.2-51.8), respectively. Our results showed a
positive relationship between the ability for biofilm formation and conferring antibiotic resistance in
ESBL-producing bacteria (OR: 3.35; 95% CI: 1.67-6.74; p-value: 0.001).

Conclusion:

In general, we showed the rate of biofilm formation to be significantly higher in ESBLproducing strains. Given the current results, the updated therapeutic guidelines should consider the role
of biofilm production for optimal therapy, treatment course, and clinical outcomes rather than the recommendation of antimicrobial agents by focusing on the results of the antibiotic susceptibility test.
Changes in Coagulation and Platelet Reactivity in People with HIV-1 Switching Between Abacavir and Tenofovir
Authors: Drabe Camilla H. , Rönsholt Frederikke F. , Jakobsen Ditte M. , Ostrowski Sisse R. , Gerstoft Jan , Helleberg Marie
Published: September 2022

Background:

Several studies have shown an association between abacavir (ABC) and increased risk of myocardial infarction (MI), but the causative mechanism has not been established. Both vascular endothelial inflammation and platelet activation have been proposed as contributing factors.

Objective:

The study aims to investigate the effects of ABC relative to tenofovir disoproxil (TDF) on functional assays of primary and secondary hemostasis and a comprehensible range of relevant biomarkers.

Methods:

In an investigator-initiated, open-labeled, crossover trial, we included HIV-infected males receiving either ABC or TDF and switched treatment to the alternate drug. At inclusion and after three months on the new regimen, we performed Multiplate® and thromboelastography (TEG®) and measured biomarkers of coagulation, inflammation, platelet reactivity, endothelial disruption and activation, and fibrinolysis, lipids, HIV RNA, CD4, CD8, and creatinine. Treatment effects were assessed by comparing intraindividual differences between the two treatment orders by the Wilcoxon Rank Sum test.

Results:

In total, 43 individuals completed the study. No intraindividual differences were observed for Multiplate® or TEG® when switching between regimens. We observed a significant treatment effect on coagulation factors II-VII-X (p<0.0001), sCD40L (a biomarker of platelet reactivity, p=0.04), thrombomodulin (biomarker of endothelial damage, p=0.04), lipids, and CD8 cell counts (p=0.04), with higher values during ABC treatment compared to TDF.

Conclusion:

Compared to TDF, ABC treatment affected several outcome measures in a pro-coagulant direction. Suggesting that the risk of MI associated with ABC may be caused by the sum of multiple, discrete disturbances in the hemostatic system and endothelium.

Study Registration:

The trial was registered at clinicaltrials.gov (NCT02093585).

Convolutional Neural Network
Authors: Liu Hanyue , Zhang Chunsheng , Wang Zichao , Lin Qingming , Lan Zhanjiang , Jiang Mingyang , Lian Jie , Chen Xueyan , Fan Xiaojing
Published: September 2022

Background:

Faced with the global threat posed by SARS-CoV-2 (COVID-19), lowdose
computed tomography (LDCT), as the primary diagnostic tool, is often accompanied by
high levels of noise. This can easily interfere with the radiologist's assessment. Convolutional
neural networks (CNN), as a method of deep learning, have been shown to have excellent effects
in image denoising.

Objective:

The objective of the study was to use modified convolutional neural network
algorithm to train the denoising model. The purpose was to make the model extract the
highlighted features of the lesion region better and ensure its effectiveness in removing noise
from COVID-19 lung CT images, preserving more important detail information of the images
and reducing the adverse effects of denoising.

Methods:

We propose a CNN-based deformable convolutional denoising neural network
(DCDNet). By combining deformable convolution methods with residual learning on the basis of
CNN structure, more image detail features are retained in CT image denoising.

Result:

According to the noise reduction evaluation index of PSNR, SSIM and RMSE, DCDNet
shows excellent denoising performance for COVID-19 CT images. From the visual effect of
denoising, DCDNet can effectively remove image noise and preserve more detailed features of
lung lesions.

Conclusion:

The experimental results indicate that the DCDNet-trained model is more suitable
for image denoising of COVID-19 than traditional image denoising algorithms under the same
training set.

EXAMINING THE EFFECT OF SERVICE VALUE AND REPUTATION ON CUSTOMER LOYALTY WITH TRUST AND ELECTRONIC WORD OF MOUTH AS MEDIATION
Authors:   Universitas Hayam Wuruk Perbanas, Burhanudin Burhanudin
Published: September 2022

To determine how banking services can lead to long-term profit, examining service value's direct and indirect effect on customer loyalty to the bank is essential. This study aims to investigate the effects of service value on customer loyalty to the bank directly and indirectly through the bank's reputation, electronic word of mouth (eWOM), and trust. This study surveyed 312 Indonesian banking customers by applying the partial least square structural equation model (PLS-SEM) to test the proposed hypotheses. This study found that the effect of service value on customer loyalty to the bank is indirect, not direct. Service value affects customer loyalty to the bank through trust and the bank's reputation. In addition, the bank's reputation affects customer loyalty to the bank through eWOM. Service value does not affect customer loyalty to the bank. This study addresses the past (represented by the bank's reputation as the firm's past action and eWOM as the customer's experience) and the future (represented by trust) to understand the relationship between service value and customer loyalty in the banking sector. The findings imply that banks need to develop their banking service value and reputation, trust, and eWOM to encourage customer loyalty to their banks.

Published: September 2022

This study investigated the association between job burnout and flexible working arrangement on employee wellbeing with perceived organizational support as a mediator. The study is conducted on 127 employees of an Indonesian telecommunication company. The data is obtained between November 2021 and January 2022 using an anonymous online survey. We employ the partial least squares-structural equation modeling (PLS-SEM) method to analyze the data. The result finds that the level of employees' job burnout is in a low category. In addition, the employees have a positive view of the FWA implementation. As for POS, the employees perceive adequate POS. The findings also reveal that the employees have a sufficiently good well-being level. Furthermore, the statistical analysis shows that the POS variable is influenced by JB and FWA variables; and has a positive and significant effect on the EW variable. In addition, JB and FWA variables have a positive and significant effect on EW, either directly or mediated by the POS variable. Note that this research was conducted at the branch of the telecommunication company at a province level. Hence, the result might not represent the employees throughout Indonesia. Moreover, the variables of interest were limited to job burnout, FWA, POS, and employee wellbeing, making a relatively limited number of operational variables. Finally, the research findings contribute to the HRM to improve the organization through employee wellbeing management.

This study focuses on perceived external prestige in reducing deviant workplace behavior by mediating job satisfaction and organizational commitment. This study aimed to determine and analyze the effect of perceived external prestige on deviant workplace behavior, either directly or indirectly, through the mediation of job satisfaction and organizational commitment. This study used saturated sampling. The sample used in this study is the civil servant of the Regional Government of Kediri Regency, East Java, especially the Regional Apparatus Organizations. Three Regional Apparatus Organizations are the Regional Personnel Agency, the Department of Transportation, and the Region Financial and Asset Management Agency, with a sample of 117 civil servants. The analytical method used is a causal study. Data were analyzed and processed using PLS-SEM statistical programming to evaluate the outer and inner structure of the model. The results reveal that perceived external prestige negatively and significantly affects deviant workplace behavior. The results of the mediation test show that job satisfaction and organizational commitment partially mediate the effect of perceived external prestige on deviant workplace behavior. Subsequent research studies will yield different results in another industry or region. Further research can conduct thorough research on all Regional Apparatus Organizations to obtain comprehensive research results, and systematic sampling techniques can be used to avoid cognitive bias from respondents.

Accumulation of defects in the synthetic quartz single crystal has been investigated at the early stages of deformation. Process is studied with the help of three independent nondestructive techniques, namely: acoustic emission, X-ray computed tomography and synchrotron radiation topography. It is shown that results obtained by the three techniques are consistent with each other, allow detecting the area of defect formation and, what is more important, to match acoustic emission parameters with the ones of defects. This result is of practical importance, since it makes it possible to further identify areas of fracture growth and estimate their size in situ only by analyzing acoustic emission data in cases where the use of other control methods is impossible. Keywords: acoustic emission, X-ray computed tomography, synchrotron radiation topography (X-ray Diffraction Imaging), quartz single crystal, defects volume.

Comparison of the results obtained for films obtained by various technologies, light scattering spectra on other types of samples, as well as comparison with the results of other authors allow us to interpret the line as the result of inelastic light scattering by one-dimensional carbon chains. Keywords: inelastic light scattering, gold films, SERS, one-dimensional carbon chains.
Impact of silicon wafer surface treatment on the morphology of GaP layers produced by plasma enhanced atomic layer deposition
Authors: Uvarov A. V.  , Sharov V. A.  , Kudryashov D. A.  , Gudovskikh A. S.
Published: September 2022

Investigations of atomic-layer deposition of GaP layers on Si substrates with different orientations and with different preliminary surface treatment have been carried out. The deposition of GaP was carried out by the method of plasma enhanced atomic-layer deposition using in situ treatment in argon plasma. It was shown that at the initial stage of the growth of GaP layers on precisely oriented (100) Si substrates and with misorientation, two-dimensional growth occurs both after chemical and plasma surface treatment. Upon growth on (111) substrates, after plasma treatment of the surface, a transition to three-dimensional growth is observed, at which the size of islands reaches 30-40 nm. The smallest root-mean-square roughness of the surface of the growing GaP layers (<0.1 nm) was achieved for (100) substrates with a misorientation of 4o. The GaP layers grown on (100) substrates had a roughness of ~0.1 nm, and on substrates with the (111) orientation --- 0.12 nm. It was found that the surface treatment of Si substrates with the (100) orientation in hydrogen plasma leads to a slight increase in the surface roughness of growing GaP layers (0.12-0.14 nm), which is associated with the effect of inhomogeneous etching of silicon in hydrogen plasma. When treating the (100) silicon surface in argon plasma, the surface roughness does not change significantly in comparison with the chemical surface treatment. On the surface of substrates with preliminary deposition of an epitaxial Si layer with a thickness of 4 nm, the morphology of GaP layers is the same as in the case of using hydrogen plasma.

Published: September 2022

Interview with Dr. Sok Cheon Pak. Dr Pak as a physiologist currently leads and guides research into nutraceuticals to provide relevant and impactful clinical applications. The best example is the rice bran arabinoxylan compound (RBAC). RBAC is a functional food produced from hydrolysed rice bran denatured with shiitake mushroom enzymes. RBAC demonstrates strong immunomodulatory properties, particularly for enhancing the natural killer cell activity. Additionally, RBAC is a potent antiproliferative food supplement with strong evidence showing that it can arrest tumour proliferation. Dr Pak has recently published a book on RBAC.
Quantifying Changes in Vaccine Coverage in Mainstream Media as a Result of the COVID-19 Outbreak: Text Mining Study
Authors: Christensen Bente , Laydon Daniel , Chelkowski Tadeusz , Jemielniak Dariusz , Vollmer Michaela , Bhatt Samir , Krawczyk Konrad
Published: September 2022

Background

Achieving herd immunity through vaccination depends upon the public’s acceptance, which in turn relies on their understanding of its risks and benefits. The fundamental objective of public health messaging on vaccines is therefore the clear communication of often complex information and, increasingly, the countering of misinformation. The primary outlet shaping public understanding is mainstream online news media, where coverage of COVID-19 vaccines was widespread.

Objective

We used text-mining analysis on the front pages of mainstream online news to quantify the volume and sentiment polarization of vaccine coverage.

Methods

We analyzed 28 million articles from 172 major news sources across 11 countries between July 2015 and April 2021. We employed keyword-based frequency analysis to estimate the proportion of overall articles devoted to vaccines. We performed topic detection using BERTopic and named entity recognition to identify the leading subjects and actors mentioned in the context of vaccines. We used the Vader Python module to perform sentiment polarization quantification of all collated English-language articles.

Results

The proportion of front-page articles mentioning vaccines increased from 0.1% to 4% with the outbreak of COVID-19. The number of negatively polarized articles increased from 6698 in 2015-2019 to 28,552 in 2020-2021. However, overall vaccine coverage before the COVID-19 pandemic was slightly negatively polarized (57% negative), whereas coverage during the pandemic was positively polarized (38% negative).

Conclusions

Throughout the pandemic, vaccines have risen from a marginal to a widely discussed topic on the front pages of major news outlets. Mainstream online media has been positively polarized toward vaccines, compared with mainly negative prepandemic vaccine news. However, the pandemic was accompanied by an order-of-magnitude increase in vaccine news that, due to low prepandemic frequency, may contribute to a perceived negative sentiment. These results highlight important interactions between the volume of news and overall polarization. To the best of our knowledge, our work is the first systematic text mining study of front-page vaccine news headlines in the context of COVID-19.
A Cognitive Behavioral Therapy Chatbot (Otis) for Health Anxiety Management: Mixed Methods Pilot Study
Authors: Goonesekera Yenushka , Donkin Liesje
Published: September 2022

Background

An increase in health anxiety was observed during the COVID-19 pandemic. However, due to physical distancing restrictions and a strained mental health system, people were unable to access support to manage health anxiety. Chatbots are emerging as an interactive means to deliver psychological interventions in a scalable manner and provide an opportunity for novel therapy delivery to large groups of people including those who might struggle to access traditional therapies.

Objective

The aim of this mixed methods pilot study was to investigate the feasibility, acceptability, engagement, and effectiveness of a cognitive behavioral therapy (CBT)–based chatbot (Otis) as an early health anxiety management intervention for adults in New Zealand during the COVID-19 pandemic.

Methods

Users were asked to complete a 14-day program run by Otis, a primarily decision tree–based chatbot on Facebook Messenger. Health anxiety, general anxiety, intolerance of uncertainty, personal well-being, and quality of life were measured pre-intervention, postintervention, and at a 12-week follow-up. Paired samples t tests and 1-way ANOVAs were conducted to investigate the associated changes in the outcomes over time. Semistructured interviews and written responses in the self-report questionnaires and Facebook Messenger were thematically analyzed.

Results

The trial was completed by 29 participants who provided outcome measures at both postintervention and follow-up. Although an average decrease in health anxiety did not reach significance at postintervention (P=.55) or follow-up (P=.08), qualitative analysis demonstrated that participants perceived benefiting from the intervention. Significant improvement in general anxiety, personal well-being, and quality of life was associated with the use of Otis at postintervention and follow-up. Anthropomorphism, Otis’ appearance, and delivery of content facilitated the use of Otis. Technical difficulties and high performance and effort expectancy were, in contrast, barriers to acceptance and engagement of Otis.

Conclusions

Otis may be a feasible, acceptable, and engaging means of delivering CBT to improve anxiety management, quality of life, and personal well-being but might not significantly reduce health anxiety.
The Implementation and Effectiveness of a Smartphone app for University Students who Self-harm (Preprint)
Authors: Cliffe Bethany , Stallard Paul
Published: September 2022

BACKGROUND

Self-harm and other mental health difficulties are very common amongst university students, but they face numerous barriers in accessing professional support. Support offered via a smartphone app may help to overcome some of the barriers they face while providing support that is acceptable and helpful.

OBJECTIVE

Evaluate the implementation and effectiveness of a self-harm prevention app BlueIce in helping students manage their self-harm, mental wellbeing and abilities to cope.

METHODS

This was a pre-post hybrid implementation and effectiveness study, where 27 participants completed baseline and follow up questionnaires assessing anxiety, depression, self-harm, and coping self-efficacy/styles. These were completed before downloading BlueIce and again 6 weeks later. After app use, they also completed a brief questionnaire evaluating BlueIce.

RESULTS

Scores of anxiety and depression significantly decreased, as did self-harm urges. Coping self-efficacy and the reappraisal coping style significantly increased. Three quarters of participants (78%) used the app and they used it on average 30 times each during the 6 week study period Feedback from participants showed that BlueIce helped provide a distraction in difficult times and helped them to manage their emotions in a more adaptive way. A quarter did not use the app with participants reporting that they did not have the energy or motivation to use it. Participants thought that BlueIce was ‘maybe’ helpful for them and for others.

CONCLUSIONS

Following app use, participants’ wellbeing had significantly improved suggesting that BlueIce may be effective in helping university students to manage their self-harm urges and wider mental health. More research is needed to generalise these findings to different student populations, but these findings nonetheless indicate that BlueIce could be an effective resource for students who are struggling.
Role of antifungal therapy in the treatment of atopic dermatitis in children
Authors: Mozyrska O.V.
Published: September 2022

Background. Atopic dermatitis is a multifactorial disease in which the microbial products of Malassezia yeast may play a certain role in triggering the disease. Topical application of zinc pyrithione has an antifungal effect and can improve the course of disease. The aim of this study was to evaluate the effectiveness of zinc pyrithione in the treatment of atopic dermatitis in children by conducting a randomized clinical trial using zinc pyrithione as an adjunct therapy. Materials and methods. Sixty-two patients with atopic dermatitis were included in the study and randomly divided into two groups: 31 people received only traditional therapy, 31 — additional topical zinc pyrithione in the form of 0.2% cream. Disease severity was evaluated using the dynamics of SCORAD (SCORing Atopic Dermatitis) indicators. Specific IgE to Malassezia was analyzed in 31 patients of the main group. Results. The improvement on the SCORAD was 45 % (T-W=496.0, p < 0.001) in the group of children who received zinc pyrithione in addition to traditional therapy, in the control group — 35.2 % (T-W = 496.0, p < 0.001). Children receiving zinc pyrithione locally had statistically significantly better dynamics on the SCORAD than controls: the average value of ΔSCORAD in the main group was 17.9, in the control group — 12.6 (W = 782.5, p = 0.006). Specific IgE to Malassezia mixture (m227) was evaluated in 31 children of the main group, among them 38.7 % had a positive result: 3 patients had class 1 sensitization; 1 — class 2; 4 — class 3; 4 children — class 5 of sensitization. Sensitization to Malassezia had not any impact on the effectiveness of treatment (W = 179.0, p = 0.597). Conclusions. This study demonstrated the effectiveness of a 3-week course of using zinc pyrithione in the treatment of atopic dermatitis as an adjunct therapy. Since the pathogenetic mechanism and interaction between Malassezia spp. and atopic dermatitis remain partially unclear, there is still a need for further research to understand the exact role of these organisms in the disease course and the role of antifungal drugs in the treatment of atopic dermatitis.

Published: September 2022

While data management planning for grant applications has become commonplace alongside articles providing guidance for such plans, examples of data plans as they have been created, implemented, and used for specific projects are only beginning to appear in the scholarly record. This article describes data management planning for an eight-institution, multi-year research project. The project leveraged four data management plans (DMP) in total, one for the funding application and one for each of the three distinct project phases. By understanding researcher roles, development and content of each DMP, team internal and external challenges, and the overall benefits of creating and using the plans, these DMPs provide a demonstration of the utility of this project management tool.
Curating for Accessibility

Published: September 2022

Accessibility of research data to disabled users has received scant attention in literature and practice. In this paper we briefly survey the current state of accessibility for research data and suggest some first steps that repositories should take to make their holdings more accessible. We then describe in depth how those steps were implemented at the Qualitative Data Repository (QDR), a domain repository for qualitative social-science data. The paper discusses accessibility testing and improvements on the repository and its underlying software, changes to the curation process to improve accessibility, as well as efforts to retroactively improve the accessibility of existing collections. We conclude by describing key lessons learned during this process as well as next steps.

Authors: Jardón Hernández Ana Elizabeth , Salas Alfaro Renato , Hernández Lara Itzel
Published: September 2022

Este documento tiene el objetivo de destacar los procesos de agencia en la experiencia de incorporación social y laboral de mexicanas y mexicanos deportados de Estados Unidos. A través de un análisis de siete narrativas digitales disponibles en el archivo Humanizando la Deportación se ofrece un acercamiento a las percepciones sobre la experiencia de población que fue deportada de ese país y se encuentran en Tijuana. El análisis de sus narrativas visibiliza a estas personas como sujetos activos con proyectos propios, es decir, con capacidad de intervenir en el contexto social en el que viven después de su deportación. Asimismo, permite identificar diversos actores sociales que desarrollan prácticas de solidaridad que favorecen la inserción laboral y la agencia de estos migrantes en contextos de dificultad y sufrimiento.
