Vegetative and productive performance of two soybean cultivars at different plant densities

The spatial arrangement and plant population have been highlighted as fundamental tools for increasing productivity. The objective was to evaluate the vegetative and productive performance of two soybean cultivars at different plant densities. Seeds of soybean cultivars (TMG 7063 IPRO and BS 2606 IPRO), recommended for the Alto Paranaíba region in the state Minas Gerais, were used and sown at seven different densities (8, 10, 12, 14, 16, 18 and 20 plants meter-1, equivalent to 160, 200, 240, 280, 280, 320, 360 and 400 thousand plants hectare-1, where they were evaluated in the development stages R1 (plant height) and R8 (height of the insertion of the first pod, plant height, number of nodes, number of branches, productivity per plant and productivity per hectare). The experiment was set up according to a randomized block design, in the factorial scheme A x B, being factor A composed by the cultivars and factor B by plant densities with three repetitions (blocks). Increased plant population resulted in greater first pod insertion height and final plant height, fewer nodes and branches and the average yield per hectare increased linearly, with the TMG 7063 IPRO cultivar being more productive under these conditions (52.7 bags of 60 kg per hectare).
Is Prone Positioning Effective in Improving Hypoxemia for Nonventilated Patients With Covid-19? A Rapid Evidence Assessment

Purpose: A relatively high percentage of patients with COVID-19 develop hypoxemia and must be mechanically ventilated. Although prone positioning (PP) has been shown to be effective in improving peripheral oxygen saturation (SpO2) in mechanically ventilated patients with hypoxemia, whether it is effective in nonventilated patients with COVID-19 is not known. The purpose of this rapid evidence assessment was to examine the effectiveness of PP on SpO2 for nonventilated adults with COVID-19 and hypoxemia. Methods: The PEDro, Medline Complete, and Cochrane Central Register of Controlled Trials databases were searched. The inclusion criteria included nonventilated adults, diagnosed with COVID-19, and treated with PP. The exclusion criteria included patients on mechanical ventilation and <18 years old. The primary outcome was SpO2, and secondary outcomes included PaO2 and PaO2/FiO2 ratio. The methodologic quality was appraised using the Scottish Intercollegiate Guidelines Network Methodology Checklist 3. Results: Eight studies met all inclusion/exclusion criteria, and a total of 199 patients were included. All studies were cohort or retrospective design, and 4 of 8 met the acceptable threshold for risk of bias. All 5 of the studies that reported SpO2 found an increase in post-PP compared with pre-PP, and 5 studies found that PaO2, PaO2/FiO2, or both increased post-PP compared with pre-PP. Conclusions: Owing to heterogeneity in methods and outcomes, as well as varied results, we conclude there is low–moderate support that PP improves SpO2 and other indicators of hypoxemia in nonventilated patients with COVID-19, but not all patients may benefit. In addition, well-controlled studies are needed to confirm these results.
Family mediation of preschool children’s digital media practices at home

ABSTRACT Although much parental mediation literature discusses restrictive mediation, less nuanced consideration has been given to the diverse nature of positive or instructional active mediation. The present study suggests family mediation of preschool children’s digital media practices at home includes a more diverse range of positive or instructional strategies than previously acknowledged. Two novel mediation practices are identified. ‘Extending’ refers to family members drawing on a child’s media interests to engage them in new (media or non-media) activities. ‘Relating’ refers to family members drawing a child’s attention to a connection between their media or non-media interests and something else (digital or non-digital). The study highlights that family members are often unaware of the extent to which they support children in developing competencies in relation to media texts and devices. Findings are based on rigorous analysis of ethnographic video observation and interview data generated in a qualitative study in the United Kingdom.
An Infodemiology and Infoveillance Study on COVID-19: Analysis of Twitter and Google Trends

Infodemiology uses web-based data to inform public health policymakers. This study aimed to examine the diffusion of Arabic language discussions and analyze the nature of Internet search behaviors related to the global COVID-19 pandemic through two platforms (Twitter and Google Trends) in Saudi Arabia. A set of Twitter Arabic data related to COVID-19 was collected and analyzed. Using Google Trends, internet search behaviors related to the pandemic were explored. Health and risk perceptions and information related to the adoption of COVID-19 infodemic markers were investigated. Moreover, Google mobility data was used to assess the relationship between different community activities and the pandemic transmission rate. The same data was used to investigate how changes in mobility could predict new COVID-19 cases. The results show that the top COVID-19–related terms for misinformation on Twitter were folk remedies from low quality sources. The number of COVID-19 cases in different Saudi provinces has a strong negative correlation with COVID-19 search queries on Google Trends (Pearson r = −0.63) and a statistical significance (p < 0.05). The reduction of mobility is highly correlated with a decreased number of total cases in Saudi Arabia. Finally, the total cases are the most significant predictor of the new COVID-19 cases.
3D Environment Exploration with SLAM for Autonomous Mobile Robot Control

In the paper a solution for building of 3D map of unknown terrain for the purposes of control of wheeled autonomous mobile robots operating in an isolated and hard-access area is described. The work environment is represented by a three-dimensional occupancy grid map built with SLAM techniques using LIDAR sensor system. Probabilistic methods such as adaptive Monte Carlo localization and extended Kalman filter are used to concurrently build a map of surroundings and a robot’s pose estimation. A robot’s displacement and orientation are obtained from odometry and inertial navigation system. All algorithms and sub-systems have been implemented and verified with Robot Operation System with a framework for exploration tasks in multi-level buildings
Simulation of intermodal shared mobility in the San Francisco Bay using MATSim

—This paper proposes a generic shared mobility simulator based on an agent-based model - MATSim. The implemented module can simulate both human and engine powered vehicles, docked/station and dockless/free-ﬂoating services, and multiple operators. The module is employed in a case study based in the San Francisco Bay Area that focuses on potential beneﬁts of docked bike-sharing services to serve as a ﬁrst/last mile solution for public transit. The initial results indicate that the current BayWheels docked bike-sharing service can potentially reduce travel time for 1049765 trips through intermodality compared to current transit travel times. By focusing our analysis on these trips that could beneﬁt from bike-sharing as a ﬁrst/last mile solution we present the quality of service indicators for different levels of adoption and two ﬂeet sizes.
Early social context does not influence behavioral variation at adulthood in ants

Abstract Early experience can prepare offspring to adapt their behaviors to the environment they are likely to encounter later in life. In several species of ants, colonies show ontogenic changes in the brood-to-worker ratio that are known to have an impact on worker morphology. However, little information is available on the influence of fluctuations in the early social context on the expression of behavior in adulthood. Using the ant Lasius niger, we tested whether the brood-to-worker ratio during larval stages influenced the level of behavioral variability at adult stages. We raised batches of 20 or 180 larvae in the presence of 60 workers until adulthood. We then quantified the activity level and wall-following tendency of callow workers on 10 successive trials to test the prediction that larvae reared under a high brood-to-worker ratio should show greater behavioral variations. We found that manipulation of the brood-to-worker ratio influenced the duration of development and the size of individuals at emergence. We detected no influence of early social context on the level of between- or within-individual variation measured for individual activity level or on wall-following behavior. Our study suggests that behavioral traits may be more canalized than morphological traits.
Determinants of Farmer’s Financing Participation in Sharia Microfinance Institutions

This study aims to analyze the determinants of farmer participation in sharia microfinance institutions. The study area covers Siak Regency and Bengkalis Regency, Riau Province. Respondents were taken as many as 30 respondents in Siak and 32 respondents in Bengkalis. The probit regression model is used to explain the factors that influence farmer participation in sharia microfinance institutions. Farmer loans are used for working capital, buying seeds and daily necessities. Most of the financing is wakalah wal mudhárabah and very few borrows in the form of wakalah wal musháraka. The results showed that the factors that influence farmer participation are education, dependency ratio, value of liquid assets owned, and farmers' income. The farther the farmer's house is from the location of the shariah microfinance institution, the less opportunity to participate. Other independent variables included in the model have no significant effect on farmers' opportunities to participate in sharia microfinance institutions in the two districts.
Stochastic evaluation of benthic biocoenosis as pollution assessment tool in a perturbed aquatic ecosystem

To analyse the extent of disturbances and determine the state of health of aquatic systems, the integration of several biological effects at different levels of biological organization has been used. One of the most valuable methods of biological effect measurements is the use of ecological surveys at community and population levels. In this study, the distributional evaluation of benthic biocoenosis was undertaken to determine site-specific differences in community assemblage in relation to environmental status of the study sites. Three study locations (Okobaba, Iddo and Tin Can Island) in the western side of the Lagos Lagoon with highest concentrations of human activities were selected. These sites represent areas directly affected by major anthropogenic discharge into the Lagos Lagoon. Samples were collected for six consecutive months (March and August 2014). There was great variation in parameters investigated among the study sites. The concentrations of dissolved oxygen in surface water varied from 3.0- 4.5 mg/L. Chlorophyll a in surface water fluctuated from 0.12- 2.01 mg/L whereas, in sediment values varied from 0.14-1.32 mg/g. Biomass of microphytobenthos (MPB) varied from 1.4-13.2 g. Of the total 841 MPB cells collected the highest population was recorded in Okobaba. Twelve MPB taxa were recorded in the study area. The most important species in terms of numerical abundance was Oscillatoria sp. This organism occurred in all the study stations and recorded a total of 113 cells in the study stretch. A major feature of the population distribution of the MPB taxa in this study is the occurrence of higher number of cells at Okobaba. The number of individuals and the distribution of BMF taxa varied greatly from one study location to another. Of the total 801 individuals collected, 398 were recorded at Okobaba, 316 occurred at Tin Can Island and 18 at Iddo. Unlike the case of MPB organisms, a fewer number of BMF taxa were recorded in the study area. The most important MBF taxon in terms of numerical abundance was Pachymelania aurita. This organism occurred in all the study sites and recorded a total of 162 individuals thereby constituting 20% of the total MBF population collected. The benthic community observed in this study was characterized by low number of individuals and the species of MPB and MBF recorded are known opportunistic species common in stressed environments.
Conceptualising games and sport teaching in physical education as a culturally responsive curriculum and pedagogy

ABSTRACT The Australian Curriculum: Health and Physical Education (Australian Curriculum, Assessment and Reporting Authority (2020a) requires all teachers to include Aboriginal and Torres Strait Islander peoples’, culture and history where there is scope to meaningfully do so. However, there is a general absence in Australia and internationally of understanding culturally responsive pedagogy for those perspectives in teaching Physical Education (PE). This concept paper proposes an educational framework comprising Yunkaporta’s (2009) 8 Ways Aboriginal Pedagogy and the Game Sense approach (GSA) (Australian Sports Commission [ASC], 1996). for games and sport teaching in PE to move towards a culturally responsive curriculum and pedagogy. We provide an empirical argument that curricula are instruments of colonisation and explain the creation of a cultural interface through games and sport as one approach for decolonising PE. We present an opportunity to ‘close the gap’ between Western and Aboriginal knowledge through the purposeful design of engagement in reconciliation, respect and recognition of continuous living Aboriginal cultures. We use the game Parndo (ASC, 2000) to illustrate an example of how Yunkaporta’s (2009) framework and the GSA become a solution for closing our identified gap. By proposing a culturally responsive curriculum, we focus on the importance of identity for all people and how curricula must be relevant and meaningful for all Australians. Importantly, Yunkaporta's (2009) 8 Ways is a product of ‘cultural interface’, co-created through dialogue between Aboriginal and non-Aboriginal educators. Our findings, although not transferable to other settings, nonetheless have relevance to other countries where there is a similar move to decolonise PE curricula.
Early Physiological Response of Potato Plants to Entomopathogenic Fungi under Hydroponic Conditions

Endophytic entomopathogenic fungi are promising agents for the promotion of plant growth, the activation of immunity, and protection against phytopathogens. However, physiological changes in plants after treatment with fungi are insufficiently studied. We investigated the effect of potato inoculation with conidia from Metarhizium robertsii and Beauveria bassiana on the growth (fresh and dry weight, length of shoots and roots, counts of stolons and leaves, and total surface area of leaves) and physiological parameters (pigment contents, free proline and malondialdehyde content, and activity of antioxidant enzymes) at the initial stage of the plant–fungus interaction (seven days) under hydroponic conditions. The results showed that the fungi could act as an immune-modulating factor for plants based on the increase in malondialdehyde and proline contents. At the same time, we observed growth retardation and a decrease in the content of photosynthetic pigments, which may be caused by a tradeoff between plant growth and the immune response.
Poor‐quality monitoring data underestimate the impact of Australia's megafires on a critically endangered songbird

Catastrophic events such as south‐eastern Australia's 2019/20 megafires are predicted to increase in frequency and severity under climate change. Rapid, well‐informed conservation prioritization will become increasingly crucial for minimizing biodiversity losses resulting from megafires. However, such assessments are susceptible to bias, because the quality of monitoring data underpinning knowledge of species' distributions is highly variable and they fail to account for differences in life history traits such as aggregative breeding. We aimed to assess how impact estimates of the 2019/20 megafires on the critically endangered regent honeyeater Anthochaera phrygia varied according to the quality of available input data and assessment methodology.
Sustainability Assessment of Modern High-Rise Timber Buildings

As woodworking and construction technologies improve, the construction of multi-storey timber buildings is gaining popularity worldwide. There is a need to look at the design of existing buildings and assess their sustainability. The aim of the present study is to assess the sustainability of modern high-rise timber buildings using multi-criteria assessment methods. The paper presents a hierarchical system of sustainability indicators and an assessment framework, developed by the authors. Based on this framework, the tallest timber buildings in different countries, i.e., Mjøstårnet in Norway, Brock Commons in Canada, Treet in Norway, Forte in Australia, Strandparken in Sweden and Stadthaus in UK, were compared across the three dimensions of sustainability (environmental, economic/technological, and social). Research has revealed that none of the buildings is leading in all dimensions of sustainability. However, each building is unique and has its own strengths. Overall multi-criteria assessment of the buildings revealed that the Brock Commons building in Canada has received the highest rank in all dimensions of sustainability. The paper contributes to the theory and practice of sustainability assessment and extends the knowledge about high-rise timber buildings. The proposed sustainability assessment framework can be used by both academics and practitioners for assessment of high-rise timber buildings.
A statistical study of three-second foreshock ULF waves observed by the Magnetospheric Multiscale mission

We perform a statistical study of 3-s ultra-low frequency (ULF) waves using Magnetospheric Multiscale observations in the Earth's foreshock region. The average phase velocity in the plasma rest frame is determined to be anti-sunward, and the intrinsic polarization is right-handed. We further examine the linear instability conditions based on the drift-bi-Maxwellian distribution functions according to the observed plasma conditions. The resulting instability is a solution to the common dispersion equation of the ion/ion right-hand non-resonant and left-hand resonant instabilities. The predicted wave propagation is also predominantly anti-sunward. The cyclotron resonant conditions of the solar wind and backstreaming beam ions are evaluated, and we find that, in some cases, the anti-sunward propagating waves can be resonant with beam ions, which was overlooked in previous studies. The study suggests that the dispersion equation provides the 3-s ULF waves a fundamental explanation that unifies a rich variety of resonant conditions.
Recreational benefits of wetlands: a survey on the Dal Lake in Jammu and Kashmir of India

PurposeA wetland is a place of tourist attraction, and tourism values play a key role in economic development. Among various services provided by a wetland, recreational services are increasingly valuable in the tourism sector. This paper aims to unfold the potential recreational values of the Dal Lake in Jammu and Kashmir, India.Design/methodology/approachThe study uses individual travel cost methods (TCMs) and assesses its impact on regional development in terms of income and employment generation. A sample of 200 tourists is selected through an on-site survey on Dal Lake, and the demand for recreational visits and its value is estimated by employing the truncated Poisson regression model (TPRM) and un-truncated Poisson regression model (UTPRM). The consumers' surplus is estimated and tourists' benefit to visiting the wetland is explored.FindingsOn average, estimated consumers' surplus per visitor is Rs 6,250 (US$96.15) and Rs 25,000 (US$384.61) from respective models. The annual total recreational value of the lake is accounted for Rs 1713m (US$ 26m). This high consumer surplus (CS) and recreational values of the lake indicate large demand for its recreational facilities.Originality/valueThe study is based on primary data and thus, is original. The paper has implications for the policymakers to formulate sustainable management plans for the proper use of Dal Lake and tourism development.
Reimagining a glocal framework: the search for academic legitimacy in Chinese public relations discipline from 1985 to 2018

ABSTRACT This paper provides a national narrative of the rise of public relations (PR) as an academic discipline in China, particularly how the PR discipline has emerged and figured in global and local historical events and struggled for legitimacy throughout China’s modernization from 1985 to 2018. Based on our historical review, five distinct periods in search of academic legitimacy have characterized the national modernization in China. Universal theoretical perspectives – PR’s introduction as a discipline in a modernizing economy – are inadequate to explain this history. By showing divergent forces affecting academic legitimacy, this study contributes a historical perspective on understanding the PR discipline in China within a glocalization context. Our paper proposes a ‘glocal’ framework to show the divergent historical stresses affecting PR’s academic legitimacy in China’s recent historical context.
Mineral chemistry and geochemistry of serpentinites from the Bianmagou ophiolite in the North Qilian Belt, NW China: Implications for protoliths, melt extractions, and melt/fluid metasomatism

The North Qilian Belt in northwestern China contains a large number of ophiolites. Most ultramafic rocks from the ophiolites have been entirely transformed into serpentinites because of extensive serpentinization, making it difficult to determine their origin and tectonic significance and further hindering advancements in the understanding of the evolutionary history of the Palaeozoic North Qilian Ocean. In this study, we present new mineral chemistry and whole‐rock geochemistry analyses (including rare earth elements, [REE]) for the serpentinites from the Bianmagou ophiolite to discuss their protoliths, geodynamic environment, melt extractions, and melt/fluid interactions. The mineral chemistry of the relic minerals (e.g., olivine, orthopyroxene, and spinel) and the whole‐rock geochemical compositions (e.g., Mg#, Ni, etc.) strongly demonstrate that the protoliths of the serpentinites were refractory mantle residues after melt extractions and probably emplaced into a tectonic regime of mid‐ocean ridge akin to abyssal peridotites. They experienced high degrees of partial melting (15–20%) recorded by spinel Cr# values and bulk incompatible elements (e.g., Ti, heavy rare‐earth element), resulting from multiple episodes of melt depletion in the lithospheric mantle. Moreover, the serpentinites commonly have U‐shaped chondrite‐normalized REE patterns. The significantly elevated LREEs probably reflect the early partial‐melting processes overprinted by later melt‐dominated metasomatism. The medium to strong enrichment of certain fluid‐mobile elements (e.g., U, Pb, Ba, Sr, As, etc.) in the studied serpentinites was a consequence of the fluid/rock interactions during serpentinization. Overall, despite the variable serpentinization they experienced, this study indicates that the mineral chemical and geochemical proxies of serpentinites provide reliable constraints on the petrogenesis and mantle metasomatism of ancient ophiolites.
