Published: March 2023

IntroductionPlant pathogens are one of the major constraints on worldwide food production. The antibiotic properties of microbes identified as effective in managing plant pathogens are well documented.MethodsHere, we used antagonism experiments and untargeted metabolomics to isolate the potentially antifungal molecules produced by KJ-34.ResultsKJ-34 is a potential biocontrol bacterium isolated from the rhizosphere soil of rice and can fight multiple fungal pathogens (i.e. Ustilaginoidea virens, Alternaria solani, Fusarium oxysporum, Phytophthora capsica, Corynespora cassiicola). The favoured fermentation conditions are determined and the fermentation broth treatment can significantly inhibit the infection of Magnaporthe oryzae and Botryis cinerea. The fermentation broth suppression ratio is 75% and 82%, respectively. Fermentation broth treatment disrupted the spore germination and led to malformation of hyphae. Additionally, we found that the molecular weight of antifungal products were less than 1000 Da through semipermeable membranes on solid medium assay. To search the potentially antifungal molecules that produce by KJ-34, we used comparative and bioinformatics analyses of fermentation broth before and after optimization by mass spectrometry. Untargeted metabolomics analyses are presumed to have a library of antifungal agents including benzoylstaurosporine, morellin and scopolamine.DiscussionThese results suggest that KJ-34 produced various biological control agents to suppress multiple phytopathogenic fungi and showed a strong potential in the ecological technologies of prevention and protection.

ObjectiveThe study was conducted to examine academic cheating behaviors and perceived online effectiveness on academic performance during the period of COVID-19 among schools, colleges, and university students in Pakistan.MethodologyA cross-sectional research design was used in the current study. Convenience sampling was used to collect the data. The study included a total sample of N = 8,590 students, with males (n = 3,270, 38%) and females (n = 5,320, 61%) participating. The data was divided into three categories: high schools (n = 1,098, 12.7%), colleges (n = 4,742, 55.2%), and universities (n = 2,570, 32.1%). School students had an average age of (M = 15, SD = 4.65), college students had an average age of (M = 20, SD = 5.64), and university students had an average age of (M = 24, SD = 5.01).ResultThe results indicated that 60% of students admitted to cheating during online exams most of the time; 30% of students admitted to cheating at least once during an online exam. The study found that students (from high school, college, and university) obtained higher grades in online exams as compared to physical exams. Furthermore, significant gender differences were found on the scales of online learning effectiveness in school, college, and university students (t = 2.3*, p = 0.05 vs. t = 4.32**, p = 0.000 vs. t = −3.3*, p = 0.04). Similarly, on the scale of academic performance, students have significant gender differences. Multivariate regression analysis confirms that students’ 26% academic performance was increased due to cheating (F (2, 8,588) = 16.24, p = 0.000). Students believe online learning is effective because academic grades are easily obtained.ConclusionCheating is more common and easier in online courses, according to more than half of respondents, and they take advantage of this. Academicians are heavily encouraged to develop morality and ethics in their students so that their institutions can produce ethical professionals for the educational community.

IntroductionHealthcare workers (HCWs) have been continually exposed to patients with COVID-19 and are at higher risk of contracting the disease. Their psychological health is important for overall wellbeing and productivity, which could lead to a reduction in human errors during the pandemic crisis. This study aimed to measure the level of concerns, work practices, adequacy of preventive measures among HCWs, and the impacts on their life and work, including mental health status during the second wave of the COVID-19 pandemic in Malaysia.MethodsAn online questionnaire was distributed randomly to 1,050 HCWs from the Ministry of Health facilities in the Klang Valley who were involved directly in managing or screening COVID-19 cases from May to August 2020. The questionnaire was divided into five domains, which were concerns, impact on life and work, practice, perceived adequacy of preventive measures, and Revised Impact of Event Scale (IES-R). Logistic regression was used to identify sociodemographic predictors of the five domains.ResultsA total of 907 respondents (86.4%) participated in this survey. Approximately half of the respondents had a low concern (50.5%), most of them had a good practice (85.1%), with 67.5% perceiving there were adequate preventive measures, and they perceived the outbreak had a low impact (92%) on their life and work. From the IES-R domain, 18.6% of respondents potentially suffered from post-traumatic stress disorder (PTSD).ConclusionDuring the second wave of the COVID-19 outbreak in Malaysia, HCWs practiced high levels of precautions and preventive measures because they were aware of the risk of infection as an occupational hazard. With the adequate implementation of policy and control measures, the psychological wellbeing of the majority HCWs remained well and adequately supported.

IntroductionWhile authentic and sustained community involvement in the research process is critically important to making new technologies and interventions effective and socially acceptable, there is uneven participation across sociodemographic, racial, and ethnic communities in many research areas, including cancer early detection research. Currently, 18% of cancer in the United States impacts Hispanics and Latinos, this population accounts for &lt; 10% of research participants. Understanding barriers and facilitators to cancer early detection research is imperative to the ultimate success of this research. Therefore, the objectives of this study were to: understand Hispanic and Latino community perspectives in participation in cancer early detection research; and identify sustainable and mutually beneficial approaches to community engagement and involvement.MethodsThe Oregon Case Study, led by Oregon Health &amp; Science University's Community Outreach, Research and Engagement (CORE) in partnership with colleagues at Vocal, a partnership between Manchester University NHS Foundation Trust and the University of Manchester and Cambridge University, adopted a participatory research approach to better understand participation in cancer early detection research from the perspectives of Oregon's Hispanic and Latino community members. We implemented two evidence-based community engagement models, the Community Engagement Studio and the Community Readiness Assessment Model. Using a facilitated format prescribed by each community engagement model, community members helped us to answer two research questions: (1) What methods help us increase participation of underrepresented communities in cancer early detection research?; and (2) How can we build trust between researchers and underrepresented communities within cancer early detection research? Quantitative (i.e., descriptive statistic) and qualitative (i.e., thematic analysis) analytic methods were used to measure and assess community knowledge, leadership, beliefs, and resources regarding participation in cancer early detection research.ResultsA total of 36 Hispanic and Latino community members participated in the two community engagement models. We identified three emergent themes pertaining to participation in cancer early detection research that include: low-level awareness of cancer early detection research and opportunities for research participation, structural barriers to research participation, and uncertainty of the benefits of research participation.ConclusionOur approach, using two evidence-based community engagement models, yielded valuable insights about perceptions of research participation for Hispanic and Latino community members. These findings, synthesized into three key themes, led to actionable recommendations to increase research participation.

BackgroundAll anesthesia providers, including nurse anesthetists and anesthesiologists work in a stressful environment with diverse tasks. The profession is characterized by high workload, both dependent and independent job descriptions, and unpredictable conditions. This study was designed and conducted to explain the factors affecting the workplace health of Iranian anesthesia teams.MethodsTwenty anesthesia team members including nurse anesthetists and anesthesiologists from 7 different hospitals were enrolled in this phenomenological research. The data were collected in 2022. Semi-structured interviews were used for data collection, and the transcripts were analyzed using qualitative content analysis.FindingsThe most notable theme emerging from the data which was found to affect workplace health was consistency of anesthesia team. Other themes derived from the data included team tranquility and physical well-being.ConclusionThe participants' emphasis was more on behavioral and managerial factors affecting workplace health, and desirable interpersonal cooperation to create a suitable work environment for them was more prominent. These findings can raise the awareness of chief nurse anesthetists and planners to provide more effective teamwork, modify the job description structure, and reduce staff conflicts.

Published: March 2023

The tetraploid germplasm of Paspalum contains a large diversity that can be used to generate better forages. The objective was to evaluate a group of Paspalum notatum and Paspalum simplex apomictic hybrids for a set of agronomic traits and apomixis expressivity. Forage yield, cold tolerance, winter regrowth, and seed yield were evaluated. The expressivity of apomixis was evaluated in P. simplex hybrids by flow cytometry. Progeny testing with molecular markers was used to determine the genotypic variability in the progeny. Differences within P. notatum and P. simplex hybrids were observed for all traits, and some of them were superior in comparison with the controls. The accumulated forage yield during three years was 988 g m−2 in the P. notatum hybrids, whereas, in P. simplex, the average forage yield per harvest (40 days of regrowth) was 180 g m−2. In P. simplex, the apomixis expressivity varied between 0 and 100%, and 65% of the hybrids showed high apomixis expressivity (superior to 70%). The genotypic mean homogeneity in the progeny was 76% and 85% in P. notatum and P. simplex, respectively. The generation of hybrids with high apomixis expressivity that combine good agronomic performance and homogeneity in the offspring is possible in tetraploid P. notatum and P. simplex.

Stationarity of species’ ecological tolerances is a first-order assumption of paleoenvironmental reconstruction based upon analog methods. To test this and other assumptions used in quantitative analysis of foraminiferal faunas for paleoceanographic reconstruction, we analyzed paired alkenone unsaturation ratio (U37K′) sea surface temperature (SST) estimates and relative abundances of planktic foraminifera within Late Pliocene assemblages. We established Pliocene temperature preferences for nine species in the North Atlantic: Dentoglobigerina altispira, Globorotalia menardii, Globoconella puncticulata, Neogloboquadrina atlantica, Neogloboquadrina incompta, Neogloboquadrina pachyderma, Trilobatus sacculifer, Globigerinita glutinata, and Globigerina bulloides. We compared these to the temperature preferences of the same extant species, and in the three cases where the species are now extinct (Dentoglobigerina altispira, Neogloboquadrina atlantica, and Globoconella puncticulata), comparisons were made to either the descendant species or other modern species commonly used as analogs. In general, the taxa tested show similar temperature responses in both Late Pliocene and present-day (core-top) distributions. The data from these comparisons are mostly encouraging, supporting past paleoceanographic conclusions, and are otherwise valuable for testing previous taxonomic grouping decisions that are often necessary for interpreting the paleoenvironment based upon Pliocene foraminiferal assemblages.

A popular investment that is in great demand among investors is stocked. Stocks are another type of financial instrument offering returns but carrying a higher risk level. Price time series are more difficult to manage than return time series. To equip investors with the knowledge to forecast future stock prices, mathematical models can be used to simulate stock price fluctuations. The time series method, especially the Integrated Moving Average (IMA) model, is a model that can be used to observe changes in stock prices. The Integrated Moving Average (IMA) model will be used in this study to simulate stock returns. The Integrated Moving Average (IMA) model is a Moving Average model that is carried out with a differencing process or an Autoregressive Integrated Moving Average model with a value of Autoregressive being zero. This study uses secondary data simulations from secondary sources, such as data on daily business stock prices for one year, to conduct a literature review and test experiments. The Integrated Moving Average (IMA) model is used in data processing, especially to test the differencing data process. The results obtained are the IMA (1,1) model with the following equation Zˆt = Zt-1 + 0, 5782at-1, which can be used to anticipate future stock returns. Based on these results, it is expected that investors can predict the value of shares within a certain period of time.

Произведена оценка задержек в IP-ориентированных сетях общего доступа, представлена концептуальная мо­дель IP-ориентированной сети. Анализ задержек пакетов IPTD произведен на исследуемом участке сети как в восходящей, так и в нисходящей ветви аналитическими методами. Средняя задержка для систем массового обслуживания определена с помощью приближенной формулы Крамера/Лангенбаха-Бельца, при этом принято, что интервалы между поступлением заявок во входном потоке нисходящей ветви подчиняются классическому распределению Парето, а на восходящую ветвь действует пуассоновский поток. Имитационные модели нисходящей и восходящей ветвей для случая анализа сегмента GPON разработаны в среде имитационного моделирования GPSS World. В результате численных исследований аналитических мо­делей и обработки результатов имитационных моделей были получены семейства кривых зависимостей средней задержки и ее среднеквадратического отклонения от параметров распределений интервалов во входном потоке для всех исследуемых видов трафика и фаз обслуживания для рассматриваемого примера GPON.
Estimation of delays in IP-oriented public access networks was calculated, a conceptual model of an IP-oriented network is presented. Analysis of IPTD packet delays was carried out on the studied section of the network both in the ascending and descending branches by analytical methods. The average delay for the queuing systems is determined using the approximate Cramer/Langenbach-Beltz formula, it is assumed that the intervals between the arrival of requests in the input stream of the descending branch obey the classical Pareto distribution, and the Poisson flow acts on the ascending branch. Simulation models of the downstream and upstream branches for the case of GPON segment analysis were developed in the GPSS World simulation environment. As a result of numerical studies of analytical models and processing of the results of simulation models, families of curves of dependencies of the average delay and its standard deviation from the parameters of the distributions of intervals in the input stream for all types of traffic and service phases for the considered GPON example were obtained.
Predation on vertebrates by Neotropical passerine birds
Authors: Lopes Leonardo E. , Fernandes Alexandre M. , Marini Miguel Â. 
Published: March 2023

We investigated if passerine birds act as important predators of small vertebrates within the Neotropics. We surveyed published studies on bird diets, and information on labels of museum specimens, compiling data on the contents of 5,221 stomachs. Eighteen samples (0.3%) presented evidence of predation on vertebrates. Our bibliographic survey also provided records of 203 passerine species preying upon vertebrates, mainly frogs and lizards. Our data suggest that vertebrate predation by passerines is relatively uncommon in the Neotropics and not characteristic of any family. On the other hand, although rare, the ability to prey on vertebrates seems to be widely distributed among Neotropical passerines, which may respond opportunistically to the stimulus of a potential food item.

Congenital heart disease (CHD) is one of the most common congenital abnormalities in children with a chronic course of disease. CHD almost always causes problem psychologically either for patients and their families. Education about CHD in children addressed to their parents and caregivers could help to overcome the emotional problems that arise while caring for children with CHD. This study was at a time to review the educational programm that can be used to improve the parental coping mechanism of children with CHD. This study is a literature review sourced from PubMed, Google Scholar andScience Directdatabases, with inclusion criteria as follows: articles published in 2015-2020, available in full text and published in Indonesian and English. Our results found 169 articles, of them only 3 that met the inclusion criteria. Implementation of empowerment-based education program was proved to improve the knowledge, parenting behavior, and self-efficacy of parents and caregivers of children with CHD. Education with audiovisual media such as photos related to diagnostic procedures could be an important first step. The level of parental anxiety was lower in the intervention group than the control group (M=63, SD=3.5 vs M=70, SD=2.8). Module-based and workshop-based intervention programs such as the Congenital Heart Disease Intervention Program (CHIP)-Family intervention or education with evidence-based Families coping programs have been shown to improve mental health and coping mechanisms for parents of children with CHD. Nursing education using various media has been proven to improve the coping mechanisms of parents of children with CHD

Published: March 2023

Health students in the final semester are focused on several activities such as completing final assignments, clinical practice in hospitals and preparing for competency tests. Teaching and learning activities for final semester students often become a burden and cause anxiety. Social support from outside has an important role in overcoming this problem. The purpose of this study is to determine the relationship between social support and anxiety of final semester students of the Anesthesiology Nursing Study Program of the University of Aisyiyah Yogyakarta. The population of this study was the seventh semester students of the Anesthesiology Nursing Study Program of the University of Aisyiyah Yogyakarta, totaling 121 students with a research sample of 95 students who were selected by random sampling technique. Data collection was done utilizing a questionnaire with The Multidimensional Scale of Perceived Social Support instrument for the social support and the Hamilton Anxiety Rating Scale instrument for the level of anxiety. Data analysis was conducted using the technique of rho spearman analysis test. The results of the analysis show that there is a significant relationship between social support and anxiety of the final semester student, with a correlation value of -0.592 and a Sig. of 0.000 (p < 0.05). In addition, the results of the analysis also show that there is a strong relationship between social support and anxiety, and the higher the social support obtained by students, the lower the level of anxiety.
