Regulation of Affective States: benefits of contact with the Nature

It has long been known of the beneficial effects of nature on human health. However, more and more, the human being is disconnected from nature. Unfortunately, our routine takes us further and further away from nature and this can be harmful to our body and mind. What implications does the lack of such contact with nature have for society as a whole? This manuscript, which is a bibliographic review, based on the psychobiological perspective, covers this subject and proposes some solutions to this issue.
Detection of Coronavirus Disease (COVID-19) Based on Deep Features

The detection of coronavirus (COVID-19) is now a critical task for the medical practitioner. The coronavirus spread so quickly between people and approaches 100,000 people worldwide. In this consequence, it is very much essential to identify the infected people so that prevention of spread can be taken. In this paper, the deep learning based methodology is suggested for detection of coronavirus infected patient using X-ray images. The support vector machine classifies the corona affected X-ray images from others using the deep feature. The methodology is beneficial for the medical practitioner for diagnosis of coronavirus infected patient. The suggested classification model, i.e. resnet50 plus SVM achieved accuracy, FPR, F1 score, MCC and Kappa are 95.38%,95.52%, 91.41% and 90.76% respectively for detecting COVID-19 (ignoring SARS, MERS and ARDS). The classification model ResNet50 plus SVM is superior compared to other classification models. The result is based on the data available in the repository of GitHub, Kaggle and Open-i as per their validated X-ray images.

Estimation of heterosis for yield and its components under normal and sodic soil in barley (Hordeum vulgare L.)

Manipulation of heterosis is considered to be a vital approach to enhance the yield potential of barley and is as accepted to be a safe strategy to overcome barriers in barley yield. Thirteen diverse Indian genotypes were crossed to obtain a series of crosses to estimate the level of heterosis and heterobeltiosis among F1 hybrids along with their parents under two contrasting environments: normal and sodic soil. Estimates revealed a significant relationship between the mean performance of F1 hybrids and their parents under sodic stress regime only. The presence of significant heterosis for grain yield was also accompanied by heterosis for yield components, such as days to 50% flowering, plant height, number of effective tillers /plant, number of spikelets /spike, number of grains/ spike, days to maturity,1000- grain weight, biological yield / plant, grain yield / plant and harvest index. The cross NDB 1245 X NDB 943 was an elite cultivar and showed significant heterobeltiosis. The study suggests that the obtained hybrids surpassed their better parents’ effects, indicative of commercial heterosis, and are thus candidates for the commercial production of hybrid barley.
Macro-maturity factors and their influence on micro-level BIM implementation within design firms in Italy

ABSTRACT Based on conceptual models of macro-BIM adoption, several factors have been proposed as indicators of BIM maturity at the national level. Such macro-level BIM maturity indicators drive policy and the institutional imperatives for smooth adoption of BIM at the micro-level (within organisations). The Italian BIM landscape is slowly progressing with several initiatives towards meeting European Union (EU) directives. It, however, remains unclear which macro-level implementation factors are most relevant to organisations in their BIM implementation. Furthermore, there is a dearth of studies exploring the relevance of proposed macro-level BIM implementation factors to BIM implementation at the micro-level. In addressing this gap, this study uses the Italian scenario to explore the role of macro-BIM maturity factors on facilitating micro-level implementation effectiveness in design firms. To achieve this aim, an exploratory study of the literature was conducted to identify macro-level factors required at the national level for BIM implementation and ascertain which of those factors are most important to design firms through a questionnaire survey of professionals within design firms, which yielded 162 responses. The research found that steps are being undertaken to improve Italy’s macro-BIM maturity with professionals having an overall good degree of awareness and positive attitude towards BIM. Based on statistical analysis, the most important macro-level initiatives to design firms is the need for embedding BIM into education curriculum as well as availability of standard deliverables and components such as BIM objects, libraries and standards that regulate their development and use.
The structure and robustness of nocturnal Lepidopteran pollen‐transfer networks in a Biodiversity Hotspot

The role of nocturnal moths within plant‐pollinator networks is poorly understood but could be important in the context of declining biodiversity and the ecosystem services they provide. For the first time, this study examined the role of moths as pollen vectors in the Mediterranean Biodiversity Hotspot. Light traps were used to sample moths in SW Portugal in 2010. The pollen on moth head parts was collected, identified, and counted to construct a nocturnal pollen‐transfer and flower‐visitor network. A total of 257 moths belonging to 95 species were captured in 11 trapping sessions in 2010; 196 moths (76%) carried pollen and the total number of pollen grains counted and identified was 9064. The pollen‐transfer network exhibited a high degree of selectivity (H2′) but low robustness when the most‐to‐least connected plants were made extinct in the network. The flower‐visitor network (based on the incidences of interactions by individual moths), however, exhibited high linkage density and was generally more robust to simulated plant or moth extinction. Including nocturnal moths in plant–pollinator networks will provide a better understanding of their robustness to species extinctions due to environmental change as well as the impacts on ecosystem structure and functioning. Nocturnal pollen–transfer networks could be developed for identifying key species for targeted conservation.
Realization of magnetoelectric effect in 50-nm-thick Cr2O3 thin film

The magnetoelectric (ME) effect is now expected as the manipulation method of antiferromagnetic (AFM) spin/domain. It is desirable that the ME effect is realized in AFM thin films to be as thin as possible. In this letter, we show that the ME effect of the Cr2O3 thin film is realized in the 50 nm thick film, less than half of the previous report ∼115 nm, based on the switching of the exchange bias polarity by the ME field cooling. We also show the magnetic-field dependence of the threshold electric field and discuss the required switching field condition from the perspective of the thickness effect.
Does economic policy uncertainty in the U.S. influence stock markets in China and India? Time-frequency evidence

ABSTRACT This paper uses continuous and discrete wavelet tools to evaluate the dynamic correlation and causality between the U.S. economic policy uncertainty (EPU) and stock markets in China and India from 1997 to 2018. The dynamic correlation in the time-frequency domain is obtained by continuous wavelet coherence, and the causality over time and frequencies is tested by the linear and non-linear Granger causality based on discrete wavelet transform. The results show that the interaction between EPU in the U.S. and stock returns in China and India is weak in the short term but gradually becomes stronger in the long term, especially when significant financial events occur. There is no Granger causality in the short term; however, there is unidirectional or bidirectional causality in the medium and long term. These conclusions may provide useful reference for policymakers and investors in Chinese and Indian stock markets to prevent cross-country risk contagion from the U.S.
COVID-19 Awareness Among Healthcare Students and Professionals in Mumbai Metropolitan Region: A Questionnaire-Based Survey

Background and objectives The rapid and extensive spread of the COVID-19 pandemic has become a major cause of concern for the healthcare profession. The aim of this study is to assess the awareness of COVID-19 disease and related infection control practices among healthcare professionals and students in the Mumbai Metropolitan Region. Materials and methods A total of 1562 responders from the Mumbai Metropolitan Region completed a questionnaire-based survey on the awareness, knowledge, and infection control practices related to COVID-19 infection in the healthcare setting. The questionnaire was adapted from the current interim guidance and information for healthcare workers published by the US Centers for Disease Control and Prevention (CDC). Convenient sampling method was used for data collection and the distribution of responses was presented as frequencies and percentages. Descriptive statistics were performed for all groups and subgroups based on the percentage of correct responses. Individual pairwise comparisons were done using the median test for the percentage of correct responses. Results The overall awareness for all subgroups was adequate with 71.2% reporting correct answers. The highest percentage of correct responses were from undergraduate medical students and the lowest was from non-clinical/administrative staff. Less than half of the total respondents could correctly define “close contact. ” More than three-fourths of the responders were aware of the various infection control measures like rapid triage, respiratory hygiene, and cough etiquette and having a separate, well ventilated waiting area for suspected COVID-19 patients. However, only 45.4% of the responders were aware of the correct sequence for the application of a mask/respirator, and only 52.5% of the responders were aware of the preferred hand hygiene method for visibly soiled hands. Conclusion There is a need for regular educational interventions and training programs on infection control practices for COVID-19 across all healthcare professions. Occupational health and safety are of paramount importance to minimize the risk of transmission to healthcare students and professionals and provide optimal care for patients.

Digital Paywall Design: Implications for Content Demand and Subscriptions

Most online content publishers have moved to subscription-based business models regulated by digital paywalls. But the managerial implications of such freemium content offerings are not well understood. We, therefore, utilized microlevel user activity data from the New York Times to conduct a large-scale study of the implications of digital paywall design for publishers. Specifically, we use a quasi-experiment that varied the (1) quantity (the number of free articles) and (2) exclusivity (the number of available sections) of free content available through the paywall to investigate the effects of paywall design on content demand, subscriptions, and total revenue. The paywall policy changes we studied suppressed total content demand by about 9.9%, reducing total advertising revenue. However, this decrease was more than offset by increased subscription revenue as the policy change led to a 31% increase in total subscriptions during our seven-month study, yielding net positive revenues of over $230,000. The results confirm an economically significant impact of the newspaper’s paywall design on content demand, subscriptions, and net revenue. Our findings can help structure the scientific discussion about digital paywall design and help managers optimize digital paywalls to maximize readership, revenue, and profit.

Micropropagation of adult Lavandula dentata plants

SummaryA protocol for in vitro propagation of adult Lavandula dentata plants has been achieved. Cultures were established by placing nodal segments on Murashige and Skoog medium containing BA, KIN, and NAA. Highest shoot multiplication rates were obtained when explants grown in the presence of 5.0 μM BA or 20 (JLM KIN were transferred to medium with 8.8 μM BA and 15% coconut milk. Multiplication efficiency through subcultures was significantly affected by the cytokinin concentration in the initial culture medium. Subculture reduced drastically the final number of shoots produced on nodal segments isolated from shoots grown in the presence of 2.0 μM BA or 40.0 μM KIN. Shoots were easily rooted on Murashige and Skoog hormone-free medium with macronutrients at half-strength. Plants were successfully transplanted into soil.
Potential Inhibitor of COVID-19 Main Protease (Mpro) From Several Medicinal Plant Compounds by Molecular Docking Study

COVID-19, a new strain of coronavirus (CoV), was identified in Wuhan, China, in 2019. No specific therapies are available and investigations regarding COVID-19 treatment are lacking. Liu et al. (2020) successfully crystallised the COVID-19 main protease (Mpro), which is a potential drug target. The present study aimed to assess bioactive compounds found in medicinal plants as potential COVID-19 Mpro inhibitors, using a molecular docking study. Molecular docking was performed using Autodock 4.2, with the Lamarckian Genetic Algorithm, to analyse the probability of docking. COVID-19 Mpro was docked with several compounds, and docking was analysed by Autodock 4.2, Pymol version 1.7. 4.5 Edu, and Biovia Discovery Studio 4.5. Nelfinavir and lopinavir were used as standards for comparison. The binding energies obtained from the docking of 6LU7 with native ligand, nelfinavir, lopinavir, kaempferol, quercetin, luteolin-7-glucoside, demethoxycurcumin, naringenin, apigenin-7-glucoside, oleuropein, curcumin, catechin, epicatechin-gallate, zingerol, gingerol, and allicin were -8.37, -10.72, -9.41, -8.58, -8.47, -8.17, -7.99, -7.89, -7.83, -7.31, -7.05, -7.24, -6.67, -5.40, -5.38, and -4.03 kcal/mol, respectively. Therefore, nelfinavir and lopinavir may represent potential treatment options, and kaempferol, quercetin, luteolin-7-glucoside, demethoxycurcumin, naringenin, apigenin-7-glucoside, oleuropein, curcumin, catechin, and epicatechin-gallate appeared to have the best potential to act as COVID-19 Mpro inhibitors. However, further research is necessary to investigate their potential medicinal use.
System 1 Is Not Scope Insensitive: A New, Dual-Process Account of Subjective Value

Companies can create value by differentiating their products and services along quantitative attributes. Existing research suggests that consumers’ tendency to rely on relatively effortless and affect-based processes reduces their sensitivity to the scope of quantitative attributes and that this explains why increments along quantitative attributes often have diminishing marginal value. The current article sheds new light on how “system 1” processes moderate the effect of quantitative product attributes on subjective value. Seven studies provide evidence that system 1 processes can produce diminishing marginal value, but also increasing marginal value, or any combination of the two, depending on the composition of the choice set. This is because system 1 processes facilitate ordinal comparisons (e.g., 256 GB is more than 128 GB, which is more than 64 GB) while system 2 processes, which are relatively more effortful and calculation based, facilitate cardinal comparisons (e.g., the difference between 256 and 128 GB is twice as large as between 128 and 64 GB).
“Why Not?”: How STEM Identity Development Promotes Black Transfer and Transition

Abstract:Policymakers have argued that increasing the number of highly skilled science, technology, engineering, and mathematics (STEM) professionals is critical to the economic stability and growth of the U.S. In addition, a desire to resolve the historically low representation of racial/ethnic-minority students in STEM has been a critical aspect of the discussion. Using science identity theory, this study explores how the tenets of science identity help Black students develop a science identity and transition from the community college to a four-year institution. Based in the results of this qualitative study, the development of science identity promoted the desire to major in a STEM degree and facilitated the transfer and transition to the university for Black students.
Verticillium longisporum and plant immunity responses in Arabidopsis

Verticillium spp. are soil-borne ascomycete fungi belonging to a subgroup of Sordariomycetes, and the three major plant pathogens Verticillium longisporum, V. dahliae and V. albo-atrum cause disease on numerous plant species worldwide. In Sweden, V. longisporum poses a threat to Brassica oilseed crops, and is thus emphasized in this thesis. Here the early immune responses to V. longisporum in the model plant Arabidopsis and recent data on the V. longisporum genome are presented. Three genes of importance in the Arabidopsis–V. longisporum interaction were studied. The genes were identified via transcriptome and single nucleotide polymorphism (SNP) analysis. RabGAP22, a RabGTPase-regulating protein, was found to contribute to V. longisporum resistance. Pull-down assays revealed SERINE:GLYOXYLATE AMINOTRANSFERASE (AGT1) as an interacting partner during V. longisporum infection and the two proteins were shown to co-localize in the peroxisomes. Unexpectedly, a role for RabGAP22 was also found in stomatal immunity. The monoterpene synthase TPS23/27 was on the other hand found to contribute to fungal invasion, by triggering germination of V. longisporum conidia. The third gene codes for a nitrate/peptide transporter, NPF5.12. Pull-down experiments and fluorescent imaging revealed interaction between NPF5.12 and a major latex protein family member, NPFBP1. Implications in plant immunity processes of these three genes are further discussed. The genomes of two Swedish V. longisporum isolates were sequenced and found to have a size of approximately 70 Mb and harbor ~21,000 protein-coding genes. Initial analyses revealed that 86% of the V. longisporum genomes are shared with V. dahliae and V. albo-atrum, with a high extent of gene duplications. Large numbers of proteins were predicted to contain secretion motifs, and this group of proteins is presumed to play major roles in the interactions with V. longisporum host plants. In conclusion, this thesis work has revealed new fungal and plant host genes and thereby laid the basis for new plant breeding and disease protection strategies.
Patterns of Understory Community Assembly and Plant Trait-Environment Relationships in Temperate SE European Forests

We analyzed variation in the functional composition and diversity of understory plant communities across different forest vegetation types in Slovenia. The study area comprises 10 representative forest sites covering broad gradients of environmental conditions (altitude, geology, light availability, soil type and reaction, nutrient availability, soil moisture), stand structural features and community attributes. The mean and variation of the trait values were quantified by community-weighted means and functional dispersion for four key plant functional traits: plant height, seed mass, specific leaf area and leaf dry matter content. At each study site, forest vegetation was surveyed at two different spatial scales (4 and 100 m2) in order to infer scale-dependent assembly rules. Patterns of community assembly were tested with a null model approach. We found that both trait means and diversity values responded to conspicuous gradients in environmental conditions and species composition across the studied forests. Our results mainly support the idea of abiotic filtering: more stressful environmental conditions (e.g., high altitude, low soil pH and low nutrient content) were occupied by communities of low functional diversity (trait convergence), which suggests a selective effect for species with traits adapted to such harsh conditions. However, trait convergence was also detected in some more resource-rich forest sites (e.g., low altitude, high soil productivity), most likely due to the presence of competitive understory species with high abundance domination. This could, at least to some extent, indicate the filtering effect of competitive interactions. Overall, we observed weak and inconsistent patterns regarding the impact of spatial scale, suggesting that similar assembly mechanisms are operating at both investigated spatial scales. Our findings contribute to the baseline understanding of the role of both abiotic and biotic constraints in forest community assembly, as evidenced by the non-random patterns in the functional structure of distinct temperate forest understories.
