Modeling of Bouncing Electron Microbursts Induced by Ducted Chorus Waves

Short‐lived (<1 s) but intense electron precipitation, known as “microbursts,” may contribute significantly to electron losses in the outer radiation belt. Their origin has been suggested to correlate with resonant scattering by whistler‐mode chorus waves, but existing models cannot fully explain the properties of microbursts, in particular, the bouncing electron packets in the form of a microburst that have been recently observed. A numerical model is presented that reproduces a series of electron bounce packets in response to individual chorus elements. Results indicate that the actual precipitation only occurs in the leading electron packet whereas subsequent packets form because of the following bounce motions of remaining fluxes. An analysis based on wave propagation and resonance condition yields an approximate time‐energy regime of electron microbursts. Such a model is valuable for interpreting and modeling low Earth‐orbiting satellite observations of electron flux variation in response to the interaction with magnetospheric chorus waves.
Absorptive capacity and in-company routines: modelling knowledge creation in the tourism industry

ABSTRACT Absorptive capacity creates valuable competitive advantages. However, the tourism sector lacks an empirical analysis of how absorptive capacity is generated and how different organisational capabilities impact on its creation. The objective of this study is to identify which are the organisational capacities that generate absorptive capacity in this sector. To do so, we develop an empirical study using the partial least square (PLS) based on 86 Ecuadorian companies, which represents a new and potent tourism destination. Our results reveal that existing knowledge consolidation, the centralisation of decision-making, knowledge formalisation, connectedness, and knowledge-management infrastructures directly and positively influence the absorptive capacity. Direct managerial implications arise, which highlight what mechanisms help create and foster absorptive capacity within companies at the touristic industry.
Molecular Characterization and Antibiotic Susceptibility of Corynebacterium pseudotuberculosis Isolated from Sheep and Goats Suffering from Caseous Lymphadenitis

Caseous lymphadenitis is a highly prevalent worldwide disease of sheep and goats caused by C. pseudotuberculosis , resulting in significant economic losses. In order to investigate the prevalence as well as the molecular characterization of C. pseudotuberculosis and monitoring the antibiotic susceptibility of the isolated strains, a total of 126 pus samples were collected aseptically from 80 sheep and 46 goats suffering from abscessation . The collected samples were subjected to bacteriological examination where the prevalence of C. pseudotuberculosis was 43.8% and 36.9% in diseased sheep and goats, respectively. The antibiotic sensitivity test was carried out using disc diffusion method, most of the isolates were resistant to penicillin (96.2%) and erythromycine (92.3%), highly sensitive to ciprofloxacin (96.2%), amikacin (90.4%) and neomycin (88.5%). Polymerase chain reaction was applied on 30 C. pseudotuberculosis isolates for the amplification and detection of both 16S rRNA and the RNA polymerase β-subunit gene ( rpo B) genes to confirm the diagnosis of the isolates. The results revealed that all the tested isolates were positive for both genes. In conclusion, the incorporation of both phenotypic and genotypic characterization of C.pseudotuberculosis is more valuable and accurate for identification of isolates. Moreover, PCR is a fast and specific diagnostic tool used for the genetic analysis of C. pseudotuberculosis.
Genetic variability determination in garden pea (Pisum sativum L sub sp. hortense Asch. and Graebn.) by using the multivariate analysis

A total of 32 genotypes collected from different geographical areas evaluated at one site to determine the genetic variability. Considerable diversity was found in different traits of horticultural importance. Principal component analysis showed more than 84 % of total multivariate variation for important traits in different genotypes. Pod yield, pod length,10 pods weight and pods per plant were found to be major traits contributing towards principal component-I. Similarly, seeds per pod, secondary branches/plant, pod length were main positive contributing traits towards second component. Ten pod weight, pod width were positively contributing component towards principal component third. Pods per plant and shelling percentage were main traits contributing to principal component-IV, where as plant height, pod length and pod width were major positively contributing traits towards principal component -V. PS-1100, Meethi Phali, PB-87 and FC-1 were most divergent genotypes. On the basis of cluster mean of single linkage cluster analysis, Custer-I was best for number of primary branches and shelling percentage, Cluster -II for plant height,10 pods weight and pod yield per plant, cluster-III for number of pods /plants and cluster IV for pod length. Selection of genotypes from divergent clusters and components having more than one positive traits for hybridization programme may lead to improvement in yield and quality of pea.
First-line therapy of metastatic colorectal cancer: does one size fit all??

© Digestive Medicine Research. All rights reserved. Dig Med Res 2020 | http://dx.doi. org/10.21037/dmr-20-21 In the study reported by Maiello and colleagues (Gruppo Oncologico dell’Italia Meridionale—GOIM 2802) and published in the January issue of Clinical Colorectal Cancer, the authors investigated the efficacy of bevacizumab combined with biweekly XELOX regimen (XELOX-2) and compared it to a more standard regimen of bevacizumab with FOLFOX-4. The authors had to be commended for doing this multicenter trial. They have concluded that the XELOX-2 with bevacizumab is an active regimen and is well tolerated. Accordingly, it might be suitable for elderly and frail patients with metastatic colorectal cancer. The trial was started in June 2011 and took 4 years and 4 months to recruit 132 patients from 8 Italian centers. Furthermore, it took the authors nearly 4 more years to publish the results. The study asked a question in 2011 that probably is not very relevant in 2020. In the design of the trial the authors decided that fluoropyrimidines, oxaliplatin and bevacizumab are effective in all metastatic colorectal cancers regardless of the KRAS status, hence both KRAS mutant and wild-type tumors were included. They have also asked a question of maintenance therapy but this result was deferred for a latter publication. The question of oral vs. intravenous fluoropyrimidines has been answered in multiple studies. The first was the N019669 trial where patients with metastatic colorectal cancer were randomized to FOLFOX vs. standard XELOX (given every 3 weeks) and to bevacizumab vs. placebo (1) (2×2 factorial design). The median progression-free survival (PFS) was equal in both XELOX and FOLFOX-4 groups [8.0 vs. 8.5 months respectively, hazard ratio (HR), 1.04; 97.5% confidence interval (CI), 0.93–1.16]. Similar results were observed for overall survival (OS) (19.8 months with XELOX vs. 19.6 months with FOLFOX-4, HR, 0.99; 97.5% CI, 0.88–1.12). Toxicity was different with more grade 3–4 neutropenia/granulocytopenia as well as febrile neutropenia in FOLFOX-4 group and more grade 3 diarrhea and hand-foot syndrome in the XELOX group. The FNCLCC (French national cancer centers) group also randomized patients to FOLFOX vs. XELOX (2) with similar results showing no statistical difference in the PFS (median 8.8 months with XELOX and 9.3 months with FOLFOX-6) and OS (median 19.9 and 20.5 months, respectively). There was more grade 3–4 thrombocytopenia (12% vs. 5%) and diarrhea (14% vs. 7%) in the XELOX group, but significantly less grade 3–4 neutropenia (5% vs. 47%), febrile neutropenia (0% vs. 6%) and neuropathy (11% vs. 26%). This comparison was also done in the secondline setting and confirmed non-inferiority of XELOX to FOLFOX in the NO16967 trial (3). In this trial XELOX was non-inferior to FOLFOX-4 for PFS (HR, 0.97; 95% CI, 0.83–1.14) and OS (HR, 1.02; 95% CI, 0.86–1.21). There were more grade 3–4 neutropenia in FOLFOX-4 Editorial Commentary
The voicer's reactions to voice: an examination of employee voice on perceived organizational status and subsequent innovative behavior in the workplace

PurposeThe purpose of this paper was to explore the voicer's own psychological or behavioral reactions to voice. A framework was proposed to predict how and when employee voice is related to innovative behavior in the workplace based on conservation of resources theory.Design/methodology/approachData was collected from a three-wave survey including 232 employees and their supervisors. Hierarchical multiple regression and PROCESS, a SPSS macro, were used to test the hypotheses.FindingsEmployee voice was positively associated with innovative behavior. Perceived organizational status mediated the link between voice and innovative behavior. Meanwhile, performance-goal orientation strengthened the positive voice–perceived organizational status and voice–innovative behavior associations.Originality/valueThis paper extended the authors’ understanding of the outcomes of voice by elucidating that voice could motivate the psychological or behavioral reactions of not only team members but also the voicer himself/herself. In addition, it highlighted the value of performance-goal orientation in strengthening the potentially positive relationship between voice and perceived organizational status. In doing so, the authors identified the unexplored individual-level psychological and behavioral reactions of the voicer himself/herself after speaking up. The present study also provided practical implications by shedding light on measures to promote innovative behavior in the workplace.
Long‐term spatial and temporal variations of vegetative drought based on vegetation condition index in China

Information concerning the spatial and temporal characteristics of vegetative drought is essential for decision-making and for many environmental and agricultural applications. This study presents a comprehensive spatio-temporal analysis of vegetative drought conditions that used the vegetation condition index (VCI) data product obtained from NOAA/AVHRR (National Oceanic and Atmospheric Administration/Advanced Very High Resolution Radiometer) to reveal the vegetative drought patterns across China from 1981 to 2015. Considering the characteristics of VCI as drought indicators, multiple methods were designed for these analyses, including drought frequency analysis, trend analysis, anomaly index analysis, and Mann-Kendall testing. The results show that China is a country with high vegetative drought frequency, but that most areas experienced only slight or moderate periods of drought. In addition, drought has obvious seasonal and geographical differences and occurs with greater frequencies in regions that are highly affected by monsoons such as the northern and southern regions—particularly in the spring and autumn. In contrast, vegetative drought frequencies in regions less affected by monsoons such as the Tibetan Plateau and the northwestern regions were much lower except in northern Sinkiang, eastern Inner Mongolia, and southern Tibet. During 1981–2015, the VCI had an increasing trend in most areas of China (except in the southern region, where it decreased), indicating a reduced frequency of vegetative drought throughout the country. Moreover, the trend was wavelike rather than a one-way change and could be divided into four phases: (1) a slowly increasing phase from 1981 to 1990, (2) an intensively fluctuating phase from 1991 to 2000, (3) a steadily increasing phase from 2001 to 2010, and (4) a slowly decreasing phase after 2010. Mann-Kendall analysis further suggested that upward trends of the VCI were more evident in spring and autumn than in summer and that both trends mutated in 1997. Specifically, the trend reached the 0.05 level of significance in the spring.

Contextual Learning Based on Multicultural Increase Students’ Knowledge Competence in Civic Education

Civic education that has not been able to give meaning to students results in the need for innovation in learning. Learning can be realized by applying contextual learning based on multiculturalism. This research is a quasi-research with nonequivalent control group design. The population in this study amounted to 130 students, while the sample in this study amounted to 44 students taken using the Cluster Random Sampling technique. The collection in this study was a multiple-choice objective test instrument of 32 questions. Based on the analysis of the polled variance t-test obtained t-count = 3.83> t-table = 1.68 at a significance level of 5% with dk = 42, which means that H0 is rejected and Ha is accepted. This proves that there are significant differences in the competence of civic knowledge between groups of students who are taught with the Multicultural Contextual learning model and students who are taught by conventional learning. So, it can be concluded that Multicultural-based Contextual learning has a significant effect on the civic knowledge competence of elementary students. The implication of this research is through the application of Multicultural-based Contextual learning students can easily interpret the learning that is done.
Population Aspects of Fishes in Geba and Sor Rivers, White Nile System in Ethiopia, East Africa

This study was carried out to assess the diversity, condition factor, length-weight relationship, and sex ratio of fishes in Geba and Sor Rivers located in Baro-Akobo Basin, White Nile system within Ethiopia. Fish samples were collected in one wet and one dry season. The length-weight relationships were fitted using power equation for the most abundant species. A total of 348 fish specimens were collected using gillnets and hooks. These were identified into eight species and one Garra sp. representing seven genera and four families. Family Cyprinidae was the most dominant with six species (66.7%). Labeobarbus intermedius, Labeobarbus nedgia, and Labeo cylindricus were the most abundant fish species, respectively, with 60.72%, 16.83%, and 14.66% index of relative importance (IRI). The diversity index was higher for Geba River ( = 1.50) than for Sor River ( = 1.10). All the three most abundant species had negative allometric growth. Seasonal variations in the mean Fulton condition factor (FCF) were statistically significant for L. cylindricus ( ). There was variation in the sex ratio with the females dominating in all the three most abundant species. Further investigation into the fish diversity, food, feeding, and reproductive behaviors of fish species especially in the tributaries of these rivers and their socioeconomic aspects is recommended.
Detecting Fraudulent Financial Reporting Using Fraud Score Model and Fraud Pentagon Theory : Empirical Study of Companies Listed in the LQ 45 Index

Misstatements and concealment of facts about the value of accounts in the financial statements indicate a fraudulent financial reporting. As a result, financial information is irrelevant and misleading. The purpose of this study was to analyze the fraud pentagon theory in detecting fraudulent financial reporting using the fraud score model of companies listed in the LQ 45 index on the Indonesia Stock Exchange in 2014-2018. The results showed financial stability, external pressure, nature of the industry, effective monitoring, change in auditors, total accruals, change in directors, the proportion of independent commissioners, frequent numbers of CEO's picture and family firms simultaneously affect the fraudulent financial reporting. Partially, financial stability and Family firms have a positive effect, external pressure and total accruals have a negative effect, and the nature of industry, effective monitoring, change in auditors, change in director, the proportion of independent commissioners, and frequent number of CEO's picture have no effect on fraudulent financial reporting. Based on the results of the research, fraud pentagon theory can be used to minimize the occurrence of fraudulent financial reporting that may be done by the company by ensuring the fairness of a financial report and assessing the risk of fraud by taking into account all aspects, especially on asset change ratios, debt ratios, accounts receivable ratios, percentage of independent audit committees change in auditors, changes in directors.
Survival and quality of hospital care for victims of car crashes in Western Azerbaijan, Iran

Background and aim: Car crashes are among the prevalent incidents seriously threatening public health. This study aimed to assess the survival and quality of hospital care for patients of car accidents in Western Azerbaijan, Iran. Methods: This cross-sectional study was conducted on 1,697 trauma victims admitted to Imam Khomeini hospital in Urmia, Iran, during 2016. The data, including systolic pressure, Glasgow Coma Scale, respiratory rate prior to admittance, severity of injuries based on surgery description, limbs and brain computed tomography scan, and diagnostic ultrasound by an specialist, were collected from medical records. The survival chance of patients was estimated using Trauma and Injury Severity Score (TRISS). To evaluate the quality of hospital service, Z and W statistics were utilized. Results: Out of 1,697 admitted victims, 1,226 (72.3%) and 471 (27.7%) subjects were male and female, respectively. The patients were within the age range of 15-54 years, including 901 (75%) male and 296 (25%) female subjects. The predominant educational levels were under diploma and illiterate in male and female patients, respectively. The mean values of the Revised Trauma Score for the recovered and deceased patients were 7.75±0.38 and 6.19±1.59, respectively; however, the mean values of the Injury Severity Score for the recovered and deceased patients were 14.57±13.72 and 52.03±27.02, respectively, indicating a statistically significant difference between the two groups. The number of observed mortalities was 69; nevertheless, the expected mortalities were 60 cases. Furthermore, the quantified W and Z statistics were -9 and 0.02, respectively. Conclusions: The results showed that the observed mortality exceeded the expected morality indicating the low quality of hospital care.
Public Toilets in a tertiary institution in the Southern part of Nigeria as Potential Reservoirs of Drug Resistant Pathogens

Toilets have long been viewed as a significant potential contributor to human infectious diseases. Various studies worldwide have explored the bacterial communities associated with toilets but only few have focused on their possible role as reservoirs of drug resistant pathogens. To explore this role, four different surfaces from a pay-to-use toilet complex at a tertiary institution in the Southern part of Nigeria were sampled using the swab-rinse technique. Sample processing was done to determine bacterial load, identify bacterial types present in the samples and determine antibiotic susceptibility using standard techniques. Similar levels of bacterial contamination were observed at all the 14 sampling points ranging from 3.6×104 to 2.7×105 CFU. A higher level of contamination was generally noted on the door handles and floor surfaces. Of the ten different bacterial groups identified, Shigella sp. and Salmonella sp. were the predominant groups (20.6% each). The test isolates showed a wide rate of resistance to antibiotics, with the highest observed against ofloxacin (98.3%) and the least against ceftriaxone (44.4%). Forty-three different antibiogram patterns were detected among the test isolates. Most of the bacteria (63.2%) were associated with MAR index values greater than 0.8. This study shows that public toilets could play a role not just as a reservoir of potential pathogens but more specifically as a potential reservoir of drug resistant pathogenic microorganisms with high MAR indices.

Save life or livelihood: Responses to COVID-19 among South-Asian poor communities

ABSTRACT We explore the COVID-19 pandemic in the way South Asian poor local communities experience health and income hazards and whether they prioritize their lives or put their lives on the line to earn a living. We conducted a descriptive analysis of the World Organizations’ data, and a content analysis of health-and-income-related documents. Analysis revealed the number of COVID-19 patients and deaths is increasing in South Asia, with the presence of inconsistent lockdown measures. Major health risks (community transmission, depression, poor emergency preparedness, and inadequate acute care) and income concerns (job losses and living cost) influence the poor communities’ psychosocial approach to life and livelihood. In many cases the poor communities do not follow lockdown and take matters into their own hands since the governments provide no welfare support. Our study highlights the importance of effective exit-strategy from lockdown, adequate acute care access, and food and income security for the community.
Optimization, characterization and antimicrobial activity of silver nanoparticles against plant bacterial pathogens phyto-synthesized by Mentha longifolia

The present study involves the Phyto-synthesis of the colloidal silver nanoparticles (AgNPs) and their applications to biologically control plant bacterial pathogens. The synthesis of AgNPs was monitored by measuring the absorbance and a characteristic surface plasmon resonance (SPR) band was observed at 450 nm. The different reaction conditions such as the temperature, incubation period, the concentration of the silver salt and the pH were optimized using the factorial design of the experiment for the better yield and the synthesis of AgNPs. The microscopic results showed that the AgNPs are anisotropic and nearly spherical and exist in the size range of ∼20–100 nm while the EDX analysis confirmed the presence of the elemental Ag. The x-ray diffraction pattern confirmed that the AgNPs are crystalline. The hydrodynamic diameter of AgNPs has measured in the range of ∼13–35 nm and the average size of a single particle was 15.55 nm. The ability of the AgNPs to biologically control the plant bacterial pathogens was measured in terms of antibacterial activity against gram-negative pathogenic bacterial strains; Pectobacterium carotovorum, Xanthomonas oryzae, Xanthomonas vesicatoria and Ralstonia solanacearum and potential antimicrobial activity were observed between 2–12 μg ml−1. The biocompatibility studies revealed that the AgNPs are highly biocompatible (LD100 208 μg ml−1) against RBCs. These findings endorse the applications of AgNPs to biological control the plant bacterial pathogens and the consumption of the plants treated with NPs is biocompatible for the humans.
