The ups and downs of felt job insecurity and job performance: The moderating role of informational justice

ABSTRACT In two intra-individual studies, we examine how felt job insecurity relates to job performance. Based on conservation of resources theory, we argue that there is a negative intra-individual relation between felt job insecurity and job performance. Informational justice is expected to moderate this within-person relationship, so that the relationship between felt job insecurity and job performance is weaker when informational justice is higher than on average. Hypotheses were tested in two studies conducted over a time span of six weeks (Study 1, N = 90) and four weeks (Study 2, N = 99) in organisations undergoing some form of change. Employees reported lower levels of contextual performance (Study 1) and productivity (Study 2) in weeks that felt job insecurity was higher than usual, unless employees perceived that their organisation had adequately informed them about the change. In the latter case, contextual performance and productivity levels remained intact. Our findings extend existing research by showing that intra-individual variations in felt job insecurity and informational justice help explain intra-individual variations in job performance. Our interpretation, though tentative, is that informational justice may serve as a substitute for the resources lost due to felt job insecurity.
Response of modern broiler chickens to dietary calcium and phosphorus levels below recommendations

Abstract This study was carried out to investigate the effects of reduced dietary calcium (Ca) and non-phytate-phosphorus (NPP) levels on performance, carcase yield and bone mineralisation of modern broilers. 11,200 one-day-old chicks (Ross-308) were divided into 7 treatments and 8 replicates with standard recommended level and six different levels of Ca and NPP reduction with completely randomised block design. Treatments were divided into following diets; T1: ross recommended control, T2: 94%, 95% and 91% as percentage of T1, T3: 94%, 95% and 83% as percentage of T1, T4: 94%, 91% and 83% as percentage of T1, T5: 94%, 91% and 77% as percentage of T1, T6: 94%, 86% and 83% as percentage of T1 and T7: 94%, 86% and 77% as percentage of T1 for starter, grower and finisher periods, respectively. Results showed that, the Ca and NPP reduction (T2–T7) through starter period did not significantly (p>.05) affect performance but when considered whole period, quadratically (p<.05) improved body weight gain (BWG), feed conversion ratio (FCR) and European Production Efficiency (EPEF). In line with, Ca and NPP intakes were decrease linearly and quadratically with Ca and NPP reducing in diet and higher intakes at T1 resulted in impaired BWG and FCR. On the other hand, carcase parameters and tibia mineralisation were not significantly affected by the reductions. In conclusion, Ca and NPP requirements of Ross 308 broilers seem to be lower than the Aviagen 2014 and 2019 recommendations and reducing almost 20% Ca and NPP intake of broilers is possible, especially after starter period, to maintain performance without any negative effect on bone development. Highlights Excessive dietary Ca and P feeding have potential deleterious effects on broilers. Dietary Ca and NPP reduction improved growth performance, without impairment bone characteristics. Especially after starter period, Ca and NPP reduction, by keeping the dietary levels as 0.90:0.45, 0.75;0.38 and 0.60;0.30% for starter, grower and finisher phase respectively, seems enough for Ross-308.
Direct Conversion of Human Fibroblasts into Osteoblasts Triggered by Histone Deacetylase Inhibitor Valproic Acid

The generation of functional osteoblasts from human somatic cells could provide an alternative means of regenerative therapy for bone disorders such as osteoporosis. In this study, we demonstrated the direct phenotypic conversion of human dermal fibroblasts (HDFs) into osteoblasts by culturing them in osteogenic medium supplemented with valproic acid (VPA), a histone deacetylase (HDAC) inhibitor. HDFs cultured with the VPA in osteogenic medium exhibited expression of alkaline phosphatase and deposition of mineralized calcium matrices, which are phenotypical characteristics of functional osteoblasts. They also expressed osteoblast-specific genes such as alkaline phosphatase, osteopontin, and bone sialoprotein, which demonstrated their direct conversion into osteoblasts. In addition, co-treatment with VPA and a specific inhibitor for activin-like kinase 5 (ALK5i II) had a synergistic effect on direct conversion. It is considered that the inductive effect of VPA on the conversion into osteoblast-lineage is due to the opening of the nucleosome structure by HDAC inhibitor, which facilitates chromatin remodeling and cellular reprogramming. Our findings provide a novel insight into the direct conversion of human somatic cells into transgene-free osteoblasts with small chemical compounds, thus making bone regeneration using cellular reprogramming strategy more clinically feasible.
Effects of nitrogen fertilizer on drought-affected corn (Zea mays)

This project explored the effects of nitrogen fertilizer on droughted corn plants. It aimed to investigate whether the amount of fertilizer would affect the rate at which the plant underwent photosynthesis. The hypothesis was that nitrogen would have little or reduced effect on a droughted plant, due to the requirement of water to undergo photosynthesis. To test this, three nitrogen treatments (zero, low, and high concentrations) and two water treatments (well-watered and droughted) were used on corn plants. Chlorophyll concentration, height, stomatal conductance, internal CO2, and photosynthesis were measured for eight weeks of treatment. Increased water primarily had an effect on the height of the plant, while the nitrogen treatments primarily affected chlorophyll content and photosynthetic rates. This suggests that while plants experience stunted growth when droughted, they do not experience a significant change in photosynthetic rates, which are decided by the nitrogen content of the soil rather than the water content.
Sustainability Analysis of the M-30 Madrid Tunnels and Madrid Río after 14 years of Service Life

In 2007, the excavation of the M-30 ring road located in Madrid and the creation of a green corridor either side of the Manzanares river brought significant change to the metropolitan area. The corridor and linear park which it provided were designed to contribute to the regeneration of the fluvial ecosystem, establish links among residents on each side of the river and promote cultural and leisure activities. This paper provides a sustainability analysis of the excavation of the M-30 (involving the socio-economic and environmental impact) 14 years after its construction. In order to show such an impact, an analysis of the area both prior to the project and after completion, as well as a hypothetical solution that uses improved materials, has been performed. This entails use of the multi-criteria decision-making model named MIVES (initials in Spanish, modelo integrado de valor para una evaluación sostenible). The MIVES method is based on the application of value functions of sustainability indicators selected by socio-economic and environmental criteria, chosen by experts. Results from analysis showed that the excavation of the M-30 considerably improved the sustainability of the area (sustainable index 3.43 and 6.26 both before and after the excavation works). However, use of improved materials in contrast with the application of conventional materials slightly improved the sustainability of the work (Sustainability Index 6.26 and 6.74, respectively, of the conventional materials).
Chromium Isotope Systematics in Modern and Ancient Microbialites

Changes in stable chromium isotopes (denoted as δ53Cr) in ancient carbonate sediments are increasingly used to reconstruct the oxygenation history in Earth’s atmosphere and oceans through time. As a significant proportion of marine carbonate older than the Cambrian is microbially-mediated, the utility of δ53Cr values in ancient carbonates hinges on whether these sediments accurately capture the isotope composition of their environment. We report Cr concentrations (Cr) and δ53Cr values of modern marginal marine and non-marine microbial carbonates. These data are supported by stable C and O isotope compositions, as well as rare earth elements and yttrium (REY) concentrations. In addition, we present data on ancient analogs from Precambrian strata. Microbial carbonates from Marion Lake (Australia, δ53Cr ≈ 0.99‰) and Mono Lake (USA, ≈0.78‰) display significantly higher δ53Cr values compared with ancient microbialites from the Andrée Land Group in Greenland (720 Ma, ≈0.36‰) and the Bitter Springs Formation in Australia (800 Ma, ≈−0.12‰). The δ53Cr values are homogenous within microbialite specimens and within individual study sites. This indicates that biological parameters, such as vital effects, causing highly variable δ53Cr values in skeletal carbonates, do not induce variability in δ53Cr values in microbialites. Together with stable C and O isotope compositions and REY patterns, δ53Cr values in microbialites seem to be driven by environmental parameters such as background lithology and salinity. In support, our Cr and δ53Cr results of ancient microbial carbonates agree well with data of abiotically precipitated carbonates of the Proterozoic. If detrital contamination is carefully assessed, microbialites have the potential to record the δ53Cr values of the waters from which they precipitated. However, it remains unclear if these δ53Cr values record (paleo-) redox conditions or rather result from other physico-chemical parameters.
Hepatitis B, Hepatitis C, and Human Immunodeficiency Virus Status in the Pregnancy

Background: Infections of hepatitis B, hepatitis C, and human immunodeficiency virus (HIV) are serious health problems worldwide and require more attentive and different management strategies in the pregnancy because of the changes in women and concerns regarding the fetuses. The study aims to determine the prevalence of these infections in the pregnancy. Methods: Pregnant women from our antenatal clinic whowere tested for hepatitis B (HB), hepatitis C (HC) from 2008 to 2018 were recruited from medical records. The prevalence of seropositivity was evaluated. Results: The prevalence rates of HBsAg, anti-HBs, anti-HCV, and anti-HIV were 1.28%, 30%, 0.18%, and 0.015%, respectively. Conclusions: In Turkey, the prevalence of hepatitis and HIV was not found as high as endemic regions of the world. It is essential to identify the infection of hepatitis and HIV for the treatment, follow-up, and fetal infection in the pregnancy.
Gyro Motor State Evaluation and Prediction Using the Extended Hidden Markov Model

This study extracted the featured vectors in the same way from testing data and substituted these vectors into a trained hidden Markov model to get the log likelihood probability. The log likelihood probability was matched with the time–probability curve from where the gyro motor state evaluation and prediction were realized. A core component of gyroscopes is linked to the reliability of the inertia system to conduct gyro motor state evaluation and prediction. This study features the vectors’ extraction from full life cycle gyro motor data and completes the training model to feature the vectors according to the time sequence and extraction to full life cycle data undergoing hidden Markov model training. This proposed model applies to full life cycle gyro motor data for validation, compared with traditional hidden Markov model predictive methods and health condition-trained data. The results suggest precise evaluation and prediction and provide an important basis for gyro motor repair and replacement strategies.
Ventricular Hypertrophy Plus Neurohumoral Activation Is Necessary to Alter the Cardiac β-Adrenoceptor System in Experimental Heart Failure

Treatment of rats with monocrotaline (MCT) leads to pulmonary hypertension, right ventricular (RV) hypertrophy, and finally to RV heart failure. This is associated with characteristic changes in right ventricular β-adrenoceptors (β-AR), neuronal noradrenaline transporter (NAT) density and activity (uptake1), and G protein–coupled receptor kinase (GRK) activity. This study aimed to find out factors that determine β-AR, uptake1, and GRK changes. Thus, 6-week-old rats were treated with 50 mg/kg MCT subcutaneous or 0.9% saline. Within 13 to 19 days after MCT application (group A), RV weight (222±6 versus 147±5 mg) and RV/left ventricular (LV) weight ratio (0.42±0.01 versus 0.29±0.01) were significantly increased, whereas plasma noradrenaline, RV β-AR density, RV NAT density and activity, and RV GRK activity were not significantly altered. Twenty-one to twenty-eight days after MCT (group B), however, not only RV weight (316±4 versus 148±2 mg) and RV/LV weight ratio (0.61±0.01 versus 0.3±0.01) were markedly inc.
EEG-based detection of the attended speaker and the locus of auditory attention with convolutional neural networks

When multiple people talk simultaneously, the healthy human auditory system is able to attend to one particular speaker of interest. Recently, it has been demonstrated that it is possible to infer to which speaker someone is attending by relating the neural activity, recorded by electroencephalography (EEG), with the speech signals. This is relevant for an effective noise suppression in hearing devices, in order to detect the target speaker in a multi-speaker scenario. Most auditory attention detection algorithms use a linear EEG decoder to reconstruct the attended stimulus envelope, which is then compared to the original stimuli envelopes to determine the attended speaker. Classifying attention within a short time interval remains the main challenge. We present two different convolutional neural network (CNN)-based approaches to solve this problem. One aims to select the attended speaker from a given set of individual speaker envelopes, and the other extracts the locus of auditory attention (left or right), without knowledge of the speech envelopes. Our results show that it is possible to decode attention within 1-2 seconds, with a median accuracy around 80%, without access to the speech envelopes. This is promising for neuro-steered noise suppression in hearing aids, which requires fast and accurate attention detection. Furthermore, the possibility of detecting the locus of auditory attention without access to the speech envelopes is promising for the scenarios in which per-speaker envelopes are unavailable. It will also enable establishing a fast and objective attention measure in future studies.
Complement component 3 as biomarker of disease activity and cardiometabolic risk factor in rheumatoid arthritis and spondyloarthritis

Objective: To analyze the relationship between complement component 3 (C3) and the prevalence of cardiometabolic risk factors and disease activity in the rheumatic diseases having the highest rates of cardiovascular morbidity and mortality: rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA). Methods: This is a cross-sectional study including 200 RA, 80 PsA, 150 axSpA patients and 100 healthy donors. The prevalence of cardiometabolic risk factors [obesity, insulin resistance, type 2 diabetes mellitus, hyperlipidemia, apolipoprotein B/apolipoprotein A (apoB/apoA) and atherogenic risks and hypertension] was analyzed. Serum complement C3 levels, inflammatory markers and disease activity were evaluated. Cluster analysis was performed to identify different phenotypes. Receiver operating characteristic (ROC) curve analysis to assess the accuracy of complement C3 as biomarker of insulin resistance and disease activity was carried out. Results: Levels of complement C3, significantly elevated in RA, axSpA and PsA patients, were associated with the prevalence of cardiometabolic risk factors. Hard clustering analysis identified two distinctive phenotypes of patients depending on the complement C3 levels and insulin sensitivity state. Patients from cluster 1, characterized by high levels of complement C3 displayed increased prevalence of cardiometabolic risk factors and high disease activity. ROC curve analysis showed that non-obesity related complement C3 levels allowed to identify insulin resistant patients. Conclusions: Complement C3 is associated with the concomitant increased prevalence of cardiometabolic risk factors in rheumatoid arthritis and spondyloarthritis. Thus, complement C3 should be considered a useful marker of insulin resistance and disease activity in these rheumatic disorders.

Stigma and mental health awareness among caregivers of patients with bipolar affective disorder

Background: Stigma and poor mental health literacy in caregivers of patients with bipolar affective disorder lead to loss of social support and occupational and financial burden reduced functioning, poor compliance and poorer quality of life for both the patient and the caregiver. With this study we aim to find out stigma and mental health awareness in caregivers of patients with bipolar affective disorder. Methods: 90 caregivers of patients diagnosed with bipolar affective disorder according to International statistical classification of diseases and related health problems (ICD-10) criteria were included in our study. Affiliate stigma scale on caregivers of people with mental illness and Public perception of mental illness questionnaire were applied on them after informed consent and acquiring socio-demographic details. Result: Analysis of the affective dimension of affiliate stigma scale on caregivers showed significant value for emotional disturbance and pressure due to care of Bipolar Affective Disorder diagnosed patient. Domains and the overall score in patients with mania was significantly more than in the patients with depression. The most significant difference (p<0.001) in the opinion of respondents was found with regards to the questions that the mental illness is caused by heredity, substance abuse, personal weakness or by God’s decree. Conclusions: Stigma towards mental disorders worsens the prognosis and compliance towards treatment, therefore, it needs to be assessed in all patients and their caregivers to improve overall well-being and improve acceptance of the patient and the caregiver in the society.
Micro-LED as a Promising Candidate for High-Speed Visible Light Communication

Visible Light Communication (VLC) technology is an emerging technology using visible light modulation that, in the modern world, will mainly facilitate high-speed internet connectivity. VLC provides tremendous advantages compared to conventional radio frequency, such as a higher transmission rate, high bandwidth, low-power consumption, no health hazards, less interference, etc., which make it more prominent in recent days. Due to their outstanding features, including low cost, low power consumption, etc., μ-light-emitting diodes (LEDs) have gained considerable attention for VLC implementation, but mostly for the ability to be used for lighting as well as communications. In this review paper, we will focus mainly on recent developments in VLC applications and various factors affecting the modulation bandwidth of VLC devices. Numerous factors, such as quantum confined stark effect (QCSE), carrier lifetime, carrier recombination time, crystal orientation, etc. affect the modulation bandwidth of LEDs, and more information will be discussed in the following sections. This paper will focus on VLC applications based on LEDs but mainly on semipolar μ-LEDs and μ-LED-based arrays with high bandwidths. Another important application of VLC is underwater optical wireless communication (UOWC), which has drawn a huge interest in marine exploration and underwater connectivity, but still faces some challenges because visible light is being used. In addition, this paper will focus on how the current VLC system modulation bandwidth can be enhanced. Many methods have been introduced, such as decreasing the active layer thickness or effective active area or using doping, but the bandwidth is restricted by the recombination time when the system configuration reaches its limit. Therefore, it is important to find alternative ways such as optimizing the system, using the blue filter or using the equalization technology, which will be addressed later. Overall, this review paper provides a brief overview of the VLC-based system performance and some of its potential prospects. Appl. Sci. 2020, 10, 7384; doi:10.3390/app10207384 www.mdpi. com/journal/applsci Appl. Sci. 2020, 10, 7384 2 of 32
The Twittering Presidents

Abstract This paper uses a Systemic Functional Multimodal Discourse Analysis (SF-MDA) approach to analyse tweets from the Twitter accounts of Presidents Barack Obama (@Barack Obama) and Donald Trump (@realDonaldTrump). The tweets were posted during the last nine months of President Obama’s effective presidency and the first nine months of President Trump’s presidency. The tweets are analysed using automated text analysis which is interpreted through an SF-MDA lens, supplemented by manual analysis. The analysis examines ideational and interpersonal emphasis in the tweets with the aim of showing how the composition and content construct a view of how each president and his presidency are presented to the public. The findings suggest marked contrasts in presidential style with President Trump foregrounding the interpersonal while President Obama foregrounds the ideational. Where President Trump presents as self-promoting, autocratic, opinionated and igniting discord in his tweets, President Obama presents as democratic, moderate, restrained and seeking social harmony.
A review of the South American genera of Cimbicidae (Insecta, Hymenoptera)

The South American genera of the Cimbicidae are reviewed. Five genera and nine species are recognized. Redescriptions of all genera and an identification key to all species are provided. All species are illustrated, including both sexes and aberrant specimens when relevant. The South American Cimbicidae are grouped in the subfamily Pachylostictinae, but there is substantial morphological divergence at the genus level. This and the isolated geographic and phylogenetic position relative to the other subfamilies of Cimbicidae indicates that the Pachylostictinae have evolved in isolation for a substantial amount of time. Host plant records are known for only one species, Pseudopachylosticta subflavata, which is mainly found in the Chacoan subregion. The distribution of the remaining species falls almost exclusively within the range of the Parana subregion forest provinces, a biome that has been much reduced by human activity in the past half millennium. It is likely that these rarely collected wasps are threatened by habitat degradation.
