(Mis)perception of bias in print media: How depth of content evaluation affects the perception of hostile bias in an objective news report
Authors: Litovsky Yana
Published: May 2021

The hostile media effect describes the tendency for partisans to evaluate media content as relatively biased against their positions. The present study investigates what specific contextual elements of a news report contribute to this effect and how it may be mitigated by the depth of content evaluation. A online study of 102 participants revealed that less bias is perceived in a newspaper article when evaluating specific aspects of the article with the text available for reference than when evaluating the overall bias without referring to the text. Moreover, being asked to consider overall article bias increased subsequent ratings of bias in the discrete elements of the text. These results suggest that the perception of media bias may be counteracted by encouraging deep, evidence-based considerations of where the alleged bias might lie, but only if this happens before the reader has the chance to form an opinion based on a cursory assessment.

Electronic mental health services (eMHSs) offer additional options for the dissemination of psychological interventions for university students. Still, many university students are reluctant to use eMHSs. Narrative messages may help increase the awareness and acceptance of quality-approved programs. However, little is known about the usefulness of narrative messages to improve attitudes towards eMHSs. In this experiment, we thus aimed to explore in how far different ways of targeting information to students affect their attitudes towards eMHSs for stress prevention and therapy, and to identify potential determinants of attitude change. N = 451 students (Mean = 32.6 years, SD = 10.2, 75% female, 7% with eMHS experience) were randomly assigned to one of four study arms involving information designed to induce different levels of perceived similarity. While the active control condition only received general information (arm 1, “information only”, n = 116), the other experimental arms were additionally exposed to testimonials on specific eMHSs either addressing an unspecified audience (arm 2, n = 112), employees (arm 3, n = 115) or working university students (arm 4, n = 108). Two-way ANOVA revealed no impact of information on the alteration of attitudes towards eMHSs for stress coping (d = 0.20). Only a small effect of target-group specific testimonials on attitudes towards online therapies was identified at post-intervention (d = 0.29). Regression analyses demonstrated significant influences of source credibility and perceived similarity on attitudes for preventative eMHSs (ps<0.01), as well as a partial mediation effect of perceived similarity in favor of testimonials targeted to students (95% CI [0.22, 0.50]). Overall, this study indicated no meaningful impact of information on attitudes and limited evidence for benefits of tailored narrative messages. Since attitudes were already positive at baseline, further research with a representative student sample mimicking real-world decision scenarios is needed to gain an in-depth understanding of acceptance-facilitating message features that may contribute to promote the adoption of evidence-based eMHSs.

To investigate the mechanisms underlying the SARS-CoV-2 infection severity observed in patients with obesity, we performed a prospective study of 51 patients evaluating the impact of multiple immune parameters during 2 weeks after admission, on vital organs’ functions according to body mass index (BMI) categories. High-dimensional flow cytometric characterization of immune cell subsets was performed at admission, 30 systemic cytokines/chemokines levels were sequentially measured, thirteen endothelial markers were determined at admission and at the zenith of the cytokines. Computed tomography scans on admission were quantified for lung damage and hepatic steatosis (n = 23). Abnormal BMI (> 25) observed in 72.6% of patients, was associated with a higher rate of intensive care unit hospitalization (p = 0.044). SARS-CoV-2 RNAaemia, peripheral immune cell subsets and cytokines/chemokines were similar among BMI groups. A significant association between inflammatory cytokines and liver, renal, and endothelial dysfunctions was observed only in patients with obesity (BMI > 30). In contrast, early signs of lung damage (ground-glass opacity) correlated with Th1/M1/inflammatory cytokines only in normal weight patients. Later lesions of pulmonary consolidation correlated with BMI but were independent of cytokine levels. Our study reveals distinct physiopathological mechanisms associated with SARS-CoV-2 infection in patients with obesity that may have important clinical implications.

Bacterial panicle blight (BPB) caused by Burkholderia glumae is one of the main concerns for rice production in the Americas since bacterial infection can interfere with the grain-filling process and under severe conditions can result in high sterility. B. glumae has been detected in several rice-growing areas of Colombia and other countries of Central and Andean regions in Latin America, although evidence of its involvement in decreasing yield under these conditions is lacking. Analysis of different parameters in trials established in three rice-growing areas showed that, despite BPB presence, severity did not explain the sterility observed in fields. PCR tests for B. glumae confirmed low infection in all sites and genotypes, only 21.4% of the analyzed samples were positive for B. glumae. Climate parameters showed that Montería and Saldaña registered maximum temperature above 34°C, minimum temperature above 23°C, and Relative Humidity above 80%, conditions that favor the invasion model described for this pathogen in Asia. Our study found that in Colombia, minimum temperature above 23°C during 10 days after flowering is the condition that correlates with disease incidence. Therefore, this correlation, and the fact that Montería and Saldaña had a higher level of infected samples according to PCR tests, high minimum temperature, but not maximum temperature, seems to be determinant for B. glumae colonization under studied field conditions. This knowledge is a solid base line to design strategies for disease control, and is also a key element for breeders to develop strategies aimed to decrease the effect of B. glumae and high night-temperature on rice yield under tropical conditions.
The impact of temporary contracts on suicide rates
Authors: Grèbol Jiménez Ricard , Vall Castelló Judit
Published: May 2021

The number of suicides has increased in the last decades in several developed countries. For instance, Spain has experienced a gradual but steady increase in suicides since the 80’s and it is currently the leading external cause of death in the country. At the same time, the dualisation of the labor market, with a strong and persistent incidence of temporary contracts, has increased the instability of employment conditions. Both developments have a stronger incidence for individuals with lower levels of education. Therefore, in this paper we use rich administrative data in order to estimate the impact of the wide spread use of temporary contracts on suicides. In order to do that we exploit a reform that liberalised the use of fix-term contracts in Spain in 1984. Our results show strong long-term effects of the reform, which increased the suicide mortality rate of affected cohorts (those entering the labor market just after the liberalisation) by at least 25.3%. We believe that this result has important policy implications and should be taken into account in the design of the national suicide prevention plans.
Outcome expectancies moderate the association between worry about climate change and personal energy-saving behaviors
Authors: Gregersen Thea , Doran Rouven , Böhm Gisela , Poortinga Wouter
Published: May 2021

This paper explores whether efficacy beliefs can alter the relationship between worry about climate change and personal energy-saving behaviors, controlling for climate change beliefs and socio-demographics. For this purpose, we used data from 23 countries that participated in the European Social Survey Round 8 (N = 44 387). Worry about climate change, personal efficacy, personal outcome expectancy, and collective outcome expectancy were each associated with personal energy-saving behaviors concerning either energy curtailment or energy efficiency. The results further show that outcome expectancies moderate the association between worry about climate change and both types of energy behaviors. Worry was more strongly related to energy curtailment behaviors among those with high levels of personal and collective outcome expectancy. A similar pattern was found for energy efficiency behaviors, which were more strongly predicted by worry about climate change when combined with high levels of collective outcome expectancy. These findings are relevant for climate change communication, especially informational campaigns aiming to lower overall household energy use.
An entry risk assessment of African horse sickness virus into the controlled area of South Africa through the legal movement of equids

Published: May 2021

South Africa is endemic for African horse sickness (AHS), an important health and trade-sensitive disease of equids. The country is zoned with movement control measures facilitating an AHS-free controlled area in the south-west. Our objective was to quantitatively establish the risk of entry of AHS virus into the AHS controlled area through the legal movement of horses. Outcomes were subcategorised to evaluate movement pathway, temporal, and spatial differences in risk. A ‘no-control’ scenario allowed for evaluation of the impact of control measures. Using 2019 movement and AHS case data, and country-wide census data, a stochastic model was developed establishing local municipality level entry risk of AHSV at monthly intervals. These were aggregated to annual probability of entry. Sensitivity analysis evaluated model variables on their impact on the conditional means of the probability of entry. The median monthly probability of entry of AHSV into the controlled area of South Africa ranged from 0.75% (June) to 5.73% (February), with the annual median probability of entry estimated at 20.21% (95% CI: 15.89%-28.89%). The annual risk of AHSV entry compared well with the annual probability of introduction of AHS into the controlled area, which is ~10% based on the last 20 years of outbreak data. Direct non-quarantine movements made up most movements and accounted for most of the risk of entry. Spatial analysis showed that, even though reported case totals were zero throughout 2019 in the Western Cape, horses originating from this province still pose a risk that should not be ignored. Control measures decrease risk by a factor of 2.8 on an annual basis. Not only do the outcomes of this study inform domestic control, they can also be used for scientifically justified trade decision making, since in-country movement control forms a key component of export protocols.

Published: May 2021

Introduction

Family planning methods are used to promote safer sexual practices, reduce unintended pregnancies and unsafe abortion, and control population. Young people aged 15–24 years belong to a key reproductive age group. However, little is known about their engagement with the family planning services in Nepal. Our study aimed to identify the perceptions of and barriers to the use of family planning among youth in Nepal.

Methods

A qualitative explorative study was done among adolescents and young people aged 15–24 years from the Hattimuda village in eastern Nepal. Six focus group discussions and 25 in-depth interviews were conducted with both male and female participants in the community using a maximum variation sampling method. Data were analyzed using a thematic framework approach.

Results

Many individuals were aware that family planning measures postpone pregnancy. However, some young participants were not fully aware of the available family planning services. Some married couples who preferred ’birth spacing’ received negative judgments from their family members for not starting a family. The perceived barriers to the use of family planning included lack of knowledge about family planning use, fear of side effects of modern family planning methods, lack of access/affordability due to familial and religious beliefs/myths/misconceptions. On an individual level, some couples’ timid nature also negatively influenced the uptake of family planning measures.

Conclusion

Women predominantly take the responsibility for using family planning measures in male-dominated decision-making societies. Moreover, young men feel that the current family planning programs have very little space for men to engage even if they were willing to participate. Communication in the community and in between the couples seem to be influenced by the presence of strong societal and cultural norms and practices. These practices seem to affect family planning related teaching at schools as well. This research shows that both young men and women are keen on getting involved with initiatives and campaigns for supporting local governments in strengthening the family planning programs in Nepal.
Effectiveness of powered exoskeleton use on gait in individuals with cerebral palsy: A systematic review
Authors: Bunge Lucinda Rose , Davidson Ashleigh Jade , Helmore Benita Roslyn , Mavrandonis Aleksandra Daniella , Page Thomas David , Schuster-Bayly Tegan Rochelle , Kumar Saravana
Published: May 2021

Background

Cerebral palsy (CP) is a leading cause of childhood disability. The motor impairments of individuals with CP significantly affect the kinematics of an efficient gait pattern. Robotic therapies have become increasingly popular as an intervention to address this. Powered lower limb exoskeletons (PoLLE) are a novel form of robotic therapy that allow the individual to perform over-ground gait training and yet its effectiveness for CP is unknown.

Purpose

To determine the effectiveness of PoLLE use on gait in individuals with CP.

Method

A systematic search of eight electronic databases was conducted in March 2020. Studies included children (0–18 years) and or adults (18+ years) diagnosed with CP who used a PoLLE for gait training. This review was conducted and reported in line with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement, with the methodology registered with PROSPERO (CRD42020177160). A modified version of the McMaster critical review form for quantitative studies was used to assess the methodological quality. Due to the heterogeneity of the included studies, a descriptive synthesis using the National Health & Medical Research Council (NHMRC) FORM framework was undertaken.

Results

Of the 2089 studies screened, ten case series and three case studies met the inclusion criteria highlighting the current evidence base is emerging and low level. A range of PoLLEs were investigated with effectiveness measured by using a number of outcome measures. Collectively, the body of evidence indicates there is some consistent positive evidence on the effectiveness of PoLLE in improving gait in individuals with CP, with minimal adverse effects. While this is a positive and encouraging finding for an emerging technology, methodological concerns also need to be acknowledged.

Conclusion

With rapidly evolving technology, PoLLEs could play a transformative role in the lives of people impacted by CP. Ongoing research is required to further strengthen the evidence base and address current methodological concerns.

Published: May 2021

Introduction

Prolotherapy and other injections, primarily acting on pathways associated with maladaptive tissue repair, are recommended for recalcitrant chronic soft tissue injuries (CSTI). However, selection of injection is challenging due to mixed results. This network meta-analysis (NMA) aimed to compare prolotherapy with other therapies, particularly injections, for CSTI and establish robustness of the results.

Methodology

Pubmed, Medline, SPORTDiscus and Google scholar were searched from inception to 4th January 2021 for randomised controlled trials (RCTs) involving injection therapies (e.g. blood derivatives, corticosteroid, hyaluronic acid, botulinum toxin) for CSTI. The primary and secondary outcomes were pain and function, respectively, at (or nearest to) 6 months. Effect size (ES) was presented as standardised mean difference with 95% confidence interval (CI). Frequentist random effect NMA was used to generate the overall estimates, subgroup estimates (by region and measurement time point) and sensitivity analyses.

Results

A total of 91 articles (87 RCTs; 5859 participants) involving upper limb (74%), lower limb (23%) and truncal/hip (3%) injuries were included. At all time points, prolotherapy had no statistically significant pain benefits over other therapies. This observation remained unchanged when tested under various assumptions and with exclusion of studies with high risk of bias. Although prolotherapy did not offer statistically significant functional improvement compared to most therapies, its ES was consistently better than non-injections and corticosteroid injection for both outcomes. At selected time points and for selected injuries, prolotherapy demonstrated potentially better pain improvement over placebo (<4 months: shoulder [ES 0.65; 95% CI 0.00 to 1.30]; 4–8 months: elbow [ES 0.91; 95% CI 0.12 to 1.70]; >8 months: shoulder [ES 2.08; 95% CI 1.49, to 2.68]). Injections generally produced greater ES when combined with non-injection therapy.

Conclusion

While clinical outcomes were generally comparable across types of injection therapy, prolotherapy may be used preferentially for selected conditions at selected times.
Effect of proximal box elevation on fracture resistance and microleakage of premolars restored with ceramic endocrowns
Authors: Zhang Hong , Li He , Cong Qian , Zhang Zhimin , Du Aobo , Wang Ying
Published: May 2021

Background

Restoration of endodontically treated premolar is in high risk for biomechanical failure, and often presents with subgingival margins. Proximal box elevation (PBE) has been used to relocate subgingival cavity outlines.

Objective

To evaluate the influence of PBE on fracture resistance and gingival microleakage of premolars with endodontic access cavities following ceramic endocrown.

Methods

Eighty sound maxillary premolars with standardized Class II cavities on mesial surfaces were randomly assigned to four groups (n = 20 in each group). Groups E1, E2 and E3, with proximal margins located in dentin/cementum, 2 mm below the cemento-enamel junction (CEJ), simulated subgingival location. Group E4 (supragingival group), with proximal margins located in enamel, 1 mm above the CEJ, was used as the positive control. For margin elevation of the proximal cavities, bulk-fill Smart Dentin Replacement (SDR), a visible light cured resin composite, was applied in group E1, and conventional resin composite (3M Z350 XT, a light-activated composite) was placed in group E2. Group E3 was only treated with a ceramic crown and served as the negative control. In all groups, computer-aided design (CAD) ceramic endocrowns were adhesively inserted, and fracture resistance, failure mode and microleakage were evaluated.

Results

A higher fracture resistance value was observed in PBE groups E1 and E2, regardless of the materials used (P = 0.038, and 0.010, respectively, vs E3), and fracture resistance in group E1 was higher than that in group E2. In teeth without PBE, the percentage of catastrophic failures reached 70%. Compared to group E3, a lower frequency distribution of microleakage was detected in supragingival group E4 (P = 0.031). No increased percentage of microleakage was observed in groups treated with PBE.

Conclusion

For endodontically treated maxillary premolars restored with ceramic endocrowns, PBE increases fracture resistance but not microleakage.
Community as soma: Reflections on a community-conscious theatre gathering
Authors: Kapadocha Christina
Published: May 2021

Taking as a point of departure the ongoing and ever-evolving interaction between theatre arts and communities, this article expands upon ideas on bodies and communities bringing together somatic, theatre and community studies. It uses as a case study a somatically inspired theatre praxis gathering that took place in the village of Kato Garouna (Corfu, Greece) during summer 2018 (23–26 August). The gathering is identified as a ‘community-conscious’ project, which led to the awareness of ‘community as soma’. This approach to community inquiry, supported by the openness of somatic and practice-research methodologies, allows the integration of embodied differences and dualities within creative co-presence. It also prompts the emergence of new interactive possibilities between newly shaped and existing groups through critical and ethical attention to invitations. Reflecting upon the methods that underlined the gathering process, communities are examined in relation to the invitations that developed them and their critical implications.
Spatial Resolution Enhancement for Large-Scale Land Cover Mapping via Weakly Supervised Deep Learning
Authors: Yu Qiutong , Liu Wei , Gonçalves Wesley Nunes , Junior José Marcato , Li Jonathan
Published: May 2021

Multispectral satellite imagery is the primary data source for monitoring land cover change and characterizing land cover globally. However, the consistency of land cover monitoring is limited by the spatial and temporal resolutions of the acquired satellite images. The public availability
of daily high-resolution images is still scarce. This paper aims to fill this gap by proposing a novel spatiotemporal fusion method to enhance daily low spatial resolution land cover mapping using a weakly supervised deep convolutional neural network. We merge Sentinel images and moderate
resolution imaging spectroradiometer (MODIS )-derived thematic land cover maps under the application background of massive remote sensing data and the large spatial resolution gaps between MODIS data and Sentinel images. The neural network training was conducted on the public data set SEN12MS,
while the validation and testing used ground truth data from the 2020 IEEE Geoscience and Remote Sensing Society data fusion contest. The proposed data fusion method shows that the synthesized land cover map has significantly higher spatial resolution than the corresponding MODIS-derived land
cover map. The ensemble approach can be implemented for generating high-resolution time series of satellite images by fusing fine images from Sentinel-1 and -2 and daily coarse images from MODIS.
A High-Resolution Satellite DEM Filtering Method Assisted with Building Segmentation

Published: May 2021

Digital elevation model (DEM) filtering is critical in DEM production, and large-area meter-level resolution DEM is mainly generated from high-resolution satellite images. However, the current DEM filtering methods are mostly aimed at laser scanning data and tend to excessively remove
ground points when processing a satellite digital surface model (DSM). To accurately filter out buildings and preserve terrain, we propose a DEM filtering algorithm using building segmentation results of orthophoto. Based on morphological filtering, our method estimates the probability of
being a built-up area or mountains for DSM, and according to this probability the filtering parameters are adaptively adjusted. For robustness, our method performs the above filtering operation on DSM through a sliding-window approach, and finally the nonground points are determined by the
votes of multiple filtering. Experiments against six representative data sets have shown that our method achieved superior perfor- mance than classical algorithms and commercial software.
Embodied Knowledge, Tool, and Sketch: Intuitive Production of Knowledge in Architectural Design
Authors: Oehlmann Nandini
Published: May 2021

Editorial Summary: Entitled »Embodied Knowledge, Tool, and Sketch«, Nandini Oehlmann's contribution directs the focus to the »intuitive production of knowledge in architectural design«, also the subtitle of the text, and aims to trace the tacit, pre-reflective knowledge that plays a guiding role in the design process. As she defines design as having »an idea in mind as a vague notion«, her investigation is driven by the search for a profound understanding of the knowledge transfer of cognitive and manual knowing. She places an emphasis on the evolution of knowledge in the design process, from indistinct premonition to a specific concretization of the design. Tacit knowledge forms the core of this research, aiming to decipher this preconscious experience-based manual or bodily knowledge. [Katharina Voigt]

Editorial Summary: In her contribution »Research / Design and Academia« Susanne Hauser discusses institutional developments and changes in academia since the 1990s, alongside which disciplinary frontiers and thematic as well as methodological approaches have been re-examined and reorganized. She highlights systemic differences in funding as well as uneven particularity in methodological attempts as fundamental reasons for the different recognition of e.g. practice-based and traditional types of academic research in architecture Against the background of her personal academic foundation in cultural studies, she traces the genesis of the architect's education as a generalist, responsible for design and conception, creation and making. Considering the specific potential of design, she argues for the recognition of designing as a specific approach to the generation of knowledge. [Katharina Voigt]

The aim of the theoretical and empirical studies presented in the article was to analyze the relationship between intimacy and interpersonal commitment experienced in love relationships during early adulthood. The study involved 172 participants asked completed Interpersonal Commitment Questionnaire and Intimacy Questionnaire. The results of the research confirmed the occurrence of a relationship between interpersonal commitment and experienced intimacy, but not in all their dimensions. It was also established that the length of the relationship does not matter for the dimensions of both experienced intimacy and interpersonal commitment. For some of them, the type of love relationship is significant.
Dostępność rodziców w dzieciństwie a przywiązanie do partnera w związku intymnym
Authors: Alabrudzińska Adamina , Bakiera Lucyna
Published: May 2021

The presented research aimed to check how, depending on different experiences in the relationship with parents during childhood, young adults function in an intimate relationship. The style of attachment to a partner was the key research category. For this purpose, the Plopa Questionnaire of Attachment Styles and survey questions were used, which allowed estimating the total index of parents’ availability. 71 people (female 50,7%) in early adulthood participated in the study. Data collection was carried out in direct contact. The results showed that a higher level of accessibility of both parents in childhood coexists with a greater intensity of the secure style of attachment to a partner in an intimate relationship. The level of parents’ availability in childhood does not correlate with unsecured styles of attachment to a partner, both among adults coming from postdivorce and full families.
When is Ambivalence Good for Family Firms? Understanding the Impact of Family Managers’ Emotional Ambivalence on Decision Making
Authors: Firfiray Shainaz , Gomez-Mejia Luis R.
Published: May 2021

It has been suggested in the family business literature that the pursuit of socioemotional wealth (SEW) has both a bright and dark side and these conflicting priorities can have a negative impact on the quality of decisions made by family managers. This paper presents a model which recognizes that ambivalence emanating from socioemotional wealth may also lead to high calibre decision-making under certain contexts. In particular, we explain how emotional ambivalence can affect the decision-making abilities of family managers. Although emotional complexity and the resulting ambivalence is seen as an undesirable situation, we argue that this could also result in positive outcomes under certain circumstances. More specifically, emotional ambivalence prompts leaders to adopt a broader perspective and consider several alternatives before reaching a decision, hence enhancing decision-making quality. However, we acknowledge that emotional ambivalence may also lead to an overly restrictive focus on the family’s interests occasionally leading to inferior family-centric decisions.
Solving realistic reactive power market clearing problem of wind-thermal power system with system security
Authors: Pagidipala Sravanthi , Vuddanti Sandeep
Published: May 2021

This paper proposes a security-constrained single and multi-objective optimization (MOO) based realistic security constrained-reactive power market clearing (SC-RPMC) mechanism in a hybrid power system by integrating the wind energy generators (WEGs) along with traditional thermal generating stations. Pre-contingency and post-contingency reactive power price clearing plans are developed. Different objective functions considered are the reactive power cost (RPC) minimization, voltage stability enhancement index (VSEI) minimization, system loss minimization (SLM), and the amount of load served maximization (LSM). These objectives of the SC-RPMC problem are solved in a single objective as well as multi-objective manner. The choice of objective functions for the MOO model depends on the load model and the operating condition of the system. For example, the SLM is an important objective function for the constant power load model, whereas the LSM is for the voltage-dependent/variable load model. The VSEI objective should be used only in near-critical loading conditions. The SLM/LSM objective is for all other operating conditions. The reason for using multiple objectives instead of a single objective and the rationale for the choice of the appropriate objectives for a given situation is explained. In this work, the teaching learning-based optimization (TLBO) algorithm is used for solving the proposed single objective-based SC-RPMC problem, and a non-dominated sorting-based TLBO technique is used for solving the multi-objective-based SC-RPMC problem. The fuzzy decision-making approach is applied for extracting the best-compromised solution. The validity and efficiency of the proposed market-clearing approach have been tested on IEEE 30 bus network.

Published: May 2021

Background: Predictive models can be used to assess the risk of readmission for patients after coronary artery bypass grafting (CABG). However, the majority of the existing prediction models have been developed based on data of western population. Our objective was to develop and validate a risk prediction model for Chinese patients after CABG.
Methods: This study was conducted among 1983 patients who underwent CABG in Wuhan Asian Heart Hospital from January 2017 to October 2019. Pearson's chi-squared and multivariate logistic regression were performed to investigate the risk factors of readmission after CABG. The area under the ROC curve and Hosmer-Lemeshow test were used to validate the discrimination and calibration of the model, respectively.
Results: Six risk factors were predictive of readmission: age≥65 years (odds ratio [OR] = 2.19; 95% confidence interval [CI]: 1.11-4.34; P = 0.024),  female (OR = 2.46; 95%CI: 1.26-4.80; P = 0.008), private insurance (OR = 4.23; 95%CI: 1.11-16.11; P = 0.034), diabetes (OR = 2.351; 95%CI: 1.20-4.59; P = 0.012), hypertension (OR = 2.33; 95%CI: 1.16-4.66; P = 0.017), and congenital heart disease (OR = 6.93;95%CI: 2.04-23.52; P = 0.002). The area under the curve c-statistic was 0.876 in the derivation sample and 0.865 in the validation sample. Hosmer-Lemeshow test: P=0.561.
Conclusion: The risk prediction model in our study can be used to predict the risk of readmission in Chinese patients after CABG.

Physics and Chemistry of Solid State Direct Reduction of Iron Ore by Hydrogen Plasma
Authors: Sabat Kali Charan
Published: May 2021

Presently, Iron is produced from iron ores by using carbon from coal. The production process is consisting of many stages. The involvement of multi-stages needs high capital investments, large-scale equipments, and produces large amounts of carbon dioxide (CO2) responsible for environmental pollution. There have been significant efforts to replace carbon with hydrogen (H2). Although H2 is the strongest reductant, it still also has thermodynamic and kinetic limitations. However, these thermodynamic and kinetic limitations could be removed by hydrogen plasma (HP). HP comprises rovibrationally excited molecular, atomic, and ionic states of hydrogen. All of them contribute to thermodynamic advantage by making the Gibbs standard free energy more negative, which makes the reduction of iron oxides feasible at low temperatures. Apart from the thermodynamic advantage, these excited species increase the internal energy of HP, which reduces the activation energy, thereby making the reduction easier and faster. Apart from the thermodynamic and kinetic advantage of HP, the byproduct of the reaction is environmentally benign water. This review discusses the physics and chemistry of iron ore reduction using HP, emphasizing the solid-state reduction of iron ore.

In order to solve the problem of the ohmic contact between the crystal surface and the metal electrode in the manufacturing process of the X/γ-ray detector, this paper uses a laser to probe the doping process of In/CdTe crystals in different media. In this experiment, the Traveling Heater Method (THM) is used to obtain CdTe(111) crystals that meet the requirements (ρ >109Ω∙cm). In and Au materials are respectively coated on the surface of the crystal sample by the vacuum thermal evaporation method to obtain the crystal sample meeting the requirements. The high-resistance p-type CdTe crystal of a relatively thick In film is irradiated with nanosecond laser pulses, the In film is used as an n-type doping source and as an electrode after laser irradiation.

CONTEXT:

Children are at increased risk of influenza-related complications. Public health agencies recommend 2 doses of influenza vaccine for children 6 months through 8 years of age receiving the vaccine for the first time.

OBJECTIVE:

To systematically review studies comparing vaccine effectiveness (VE) and immunogenicity after 1 or 2 doses of inactivated influenza vaccine (IIV) in children.

DATA SOURCES:

Data sources included Medline, Embase, and Cochrane Library databases.

STUDY SELECTION:

We included studies published in a peer reviewed journal up to April 2, 2019, with available abstracts, written in English, and with children aged 6 months through 8 years.

DATA EXTRACTION:

VE among fully and partially vaccinated children was compared with that of unvaccinated children. We extracted geometric mean titers of serum hemagglutination inhibition (HAI) antibodies against influenza A(H1N1), A(H3N2), and B-lineage vaccine antigens after 1 and 2 IIV doses. Outcomes were evaluated by age, timing of doses, vaccine composition, and prevaccination titers.

RESULTS:

A total of 10 VE and 16 immunogenicity studies were included. VE was higher for fully vaccinated groups than partially vaccinated groups, especially for children aged 6–23 months. Our findings show increased HAI titers after 2 doses, compared with 1. Older children and groups with prevaccination antibodies have robust HAI titers after 1 dose. Similar vaccine strains across doses, not the timing of doses, positively affects immune response.

LIMITATIONS:

Few studies focused on older children. Researchers typically administered one-half the standard dose of IIV. HAI antibodies are an imperfect correlate of protection.

CONCLUSIONS:

Findings support policies recommending 2 IIV doses in children to provide optimal protection against influenza.

BACKGROUND AND OBJECTIVES:

Attention-deficit/hyperactivity disorder (ADHD) and obesity are 2 frequent conditions that co-occur, which has implications for the management of both conditions. We hypothesized that ADHD symptoms predict BMI and vice versa from late childhood (10–12 years) up to early adulthood (20–22 years).

METHODS:

Participants were adolescents in the Netherlands (n = 2773, 52.5% male, mean age = 11 years at baseline, 5 waves up to mean age 22) from the Tracking Adolescents’ Individual Lives Survey cohort. We examined bidirectional relationship between ADHD symptoms (hyperactivity/impulsivity and inattention) and BMI using the random intercept cross-lagged panel model. Time-varying covariates were pubertal status, stimulant use, depressive symptoms, and family functioning, and socioeconomic status was a time-invariant covariate.

RESULTS:

We found a time-invariant association of BMI with hyperactivity and impulsivity, but not with inattention, which was slightly stronger in female adolescents (female: r = 0.102; male: r = 0.086, P < .05). No longitudinal direct effects were found between ADHD symptoms and BMI during this period.

CONCLUSIONS:

Over the course of adolescence, the link between ADHD and BMI is stable and is predominantly with hyperactive and impulsive symptoms rather than inattention. There was no direct effect of ADHD symptoms on BMI increase nor of BMI on enhanced ADHD symptoms during this developmental period. The findings point to a shared genetic or familial background and/or potential causal effects established already earlier in childhood, thus suggesting that intervention and prevention programs targeting overweight and obesity in children with ADHD should be implemented in early childhood.

The objective of this research was to evaluate the immediate and latent drying temperature damages on the physical and physiological quality of black oat seeds. The seeds were dried in an oven with air circulation at temperatures of 30, 40 and 50ºC, in addition to the use of alternating temperatures (40-50ºC). After drying the seeds were stored under environmental conditions for 180 days, and physical and physiological analyses were performed every 45 days. It was observed that the physical quality of black oat seeds was reduced with an increase in the storage time, regardless of the drying temperature used. The physiological quality of black oat seeds increased throughout storage until dormancy was overcome, regardless of the drying temperature. Elevated drying temperatures cause immediate damages to the physical quality of black oat seeds, whereas physiological quality tends latently to suffer the negative influence of increasing the temperature of the drying air.

As a control measure against weeds, the use of herbicides is an effective and inexpensive alternative. However, there are no products recommended for the cultivation of cowpea in Brazil, making it necessary to search for alternative solutions. The objective of this study was to evaluate the effect of herbicides applied in the pre- and post-emergence on cowpea nodulation and production under conditions of the Amazonian savannah. Two experiments were carried out in a randomized block design with four replicates, using the cowpea cultivar BRS Aracê subjected to the pre-emergence herbicides: Metribuzin, Sulfentrazone, Smetolachlor, Pendimethalin, Oxadiazon, Alachlor, Metribuzin + Pendimethalin, Metribuzin + Alachlor and Quizalofop-p-ethyl, Bentazon, Fomesafen, Imazethapyr, Imazamox + Bentazon, Quizalofop-p-ethyl + Imazethapyr, Quizalofop-p-ethyl + Imazamox and Quizalofop-p-ethyl + Bentazon, and post-emergence herbicides: Quizalofop-p-ethyl, Bentazon, Fomesafen, Imazethapyr, Imazamox + Bentazon, Quizalofop-p-ethyl + Imazethapyr, Quizalofop-p-ethyl + Imazamox, and Quizalofop-p-ethyl + Bentazon. The number of nodules in each plant, the dry matter of nodules, dry matter of roots and the grain yield were evaluated. According to the results obtained, the management of weeds in pre- or post-emergence according to the herbicide used affects the nodulation and productivity of cowpea under the conditions of the Amazonian savannah. The herbicides Metribuzin in preemergence,and Fomesafen and the mixture of Quizalofop-pethyl + Imazethapyr in post-emergence are not recommended for weed control in cowpea. The application of Oxadiazon, Alachlor, and Pendimethalin in pre-emergence can be considered interesting because they do not inhibit the development of the root system or the nodulation of cowpea which provides agreater grain yield. Regarding weed control strategies at postemergence, the application of the herbicide Imazethapyr and the combination of the herbicides quizalofop-p-ethyl + imazamox, Quizalofop-p-ethyl + Bentazon and Imazamox + Bentazon allow satisfactory levels of grain yield, root system development and nodulation of cowpea.

Agricultural intensification has led to an elevated use of pesticides and fertilizers such as urea, without considering the negative effects these products can cause, such as acidification of the soil and the entry of lead (Pb) into the trophic chain. The objective of this research was to determine the effect of urea on the absorption of lead (Pb) in the leaf structure of corn (Zea mays L.), spinach (Spinacia oleracea L.), and cabbage (Brassica oleracea L.). These three plant species were exposed to five different concentrations of urea and a constant concentration of Pb in the form of Pb acetate for 93 days. The effect of urea and Pb was determined through analysis of the leaf structure. The results showed an increase in the dry weight of corn, whereas in spinach (T4) (1.5 g urea kg-1 of soil plus 0.5 g Pb kg-1 of soil) dry weight decreased as well as the fresh weight and foliar area. An increase in the chlorophyll index in corn, spinach, and cabbage was observed in the treatments with urea, and there was an influence on soil acidification. We also observed that spinach concentrated more Pb (T4) in its foliage at higher rates of N application. The idiosyncratic nature of the crop combined effects of Pb and N highlights the need for more research on this subject.
