The relationships among charismatic leadership, job satisfaction, and entrepreneurial orientation: An empirical study in the R&D department

In the context of social learning theory, this study aims to determine how the charismatic leadership of managers affects the entrepreneurial orientation of R&D employees and whether job satisfaction has any mediating effect in this relationship. In this context, data were collected through questionnaire method from 392 employees working in the R&D departments of the companies operating in the manufacturing industry, which are included in the Top 500 Industrial Enterprises List of Turkey. The data were analyzed with the SPSS 22.0 package program. As a result of the analyses, it was found out that the managers’ charismatic leadership behaviours affect job satisfaction and entrepreneurship orientation of the R&D employees. Furthermore, the job satisfaction of the R&D employees has a partial mediating effect in the relationship between charismatic leadership and entrepreneurial leadership orientation. These findings show that organizations will increase their entrepreneurial exposure by influencing the job satisfaction of their employees with a charismatic leadership approach.
Numerical Parametric Study of Fully Encased Composite Columns Subjected to Cyclic Loading

This paper investigates the cyclic behaviour of steel-concrete encased composite columns. By investigating the cover concrete and the steel-concrete coefficient of friction on the behaviour (strength, ductility, stiffness, and energy dissipation) of composite columns subjected to combined axial load and cyclically increasing lateral load to improve the strength and performance of the composite column. Eight of the columns were designed to study the cover concrete effect, and eleven other columns were designed to study the coefficient of friction effect in the dynamic behaviour to the cyclic load. Additionally, in this study, the finite element models created in ANSYS software were verified and calibrated against previously published experimental results (load-displacement curve, load capacity and failure mode). The numerical results obtained from the finite element model indicate that the ductility and the energy dissipated increased by +11.71 and +18.93% receptively by the increase of the cover concrete until reaching the limit of the cover concrete. Beyond this limit, the ductility and the energy decrease by 27.33 and 24.97% receptively. The results also indicate that the ductility and the energy dissipated increased by 12.62 and 7.82% receptively by the increased coefficient of friction until reach 0.6, after that the energy decreases by 4.47%.

Risk factors of anemia among selected countries experiencing higher rate of under-5 mortality in sub-Saharan Africa: a three-way interaction model

Background: Over 1.8 million under-five mortality could be avoided each year if anemia is dealt with. No adequate information on the determinants of anemia among the sub-Saharan countries experiencing a higher after prevalence under-5 mortality. This study identified the risk factors of anemia among three sub-Saharan countries (Benin, Guinea and Nigeria). Methods: A total of 24137 records from the 2018 demographic and health survey. The outcome variable was anemia status (Anemic=1, not anemic=0). Measures of effects (AOR) were assessed using binary logistic regression and random-effect generalized linear model. Stata MP 16 was used for the data analysis.Results: Anemia was found to be common among children in Nigeria (ENREF 59.4%), Benin (58.2%), and Guinea (46.0%). Children (<6 months) had higher risk of anemia (AOR: 1.20, 95% CI: 1.05-1.37). Intake of drugs for the treatment of intestinal parasites during pregnancy was found to be protective against anemia in Nigeria (AOR: 0.85, 95% CI: 0.89-0.97) and Guinea (AOR: 0.76, 95% CI: 0.63-0.91). Main cooking fuel: Kerosene (AOR: 1.32, 95% CI: 1.05-1.65) and firewood (AOR: 1.46, 95% CI: 1.17-1.81) were associated with a higher risk of anemia.Conclusions: Children of younger age (<6 months) deserve priority attention in the battle against anemia. Intake of drugs for intestinal parasites during pregnancy presents a potentially impactful strategy for anemia prevention among under-5 children in addition to routine deworming and treatments. Also, rural residents, users of kerosene and firewood as main cooking fuel, and users of unprotected well as main source of drinking water needs attention in the awareness and campaigns against under-5 anemia.
Parasitic Infection Patterns in Coleodactylus Meridionalis (Squamata: Sphaerodactylidae) from Atlantic Forest Fragments, Northeast of The Neotropical Region

Summary Studies that seek to understand which factors influence the patterns of infection in the lizard Coleodactylus meridionalis are non-existent. In this way, we recorded the infection rates for these lizards from three different sized fragments of the Atlantic rainforest and investigated if there is influence of the size, mass and sex of the host regarding the endoparasite abundance. In addition, we investigated if there were possible associations between the host’s diet and parasitism, by calculating the diet niche breadth (based on the prey number of pooled stomachs) for each host population and comparing the diet between fragments and sexes (from the three sampled fragments). We collected 38 lizards across the three sampled forest fragments. We only found parasites in the lizards sampled from the smallest of the three forest fragments which included: Physaloptera lutzi, Haplometroides odhneri and Oligacanthorhynchus sp. For this population, lizards with greater length and body mass have a greater endoparasite abundance. In addition, based on the results obtained in our study, the diet of the lizards varies in food composition between sampled populations. Finally, knowing that among the infected lizards there is no sexual dimorphism in relation to size and body mass and that the stomach sampling for this population is insufficient to calculate the indexes related to the food niche; we used the number of prey lizards from all populations, thus we were able to associate the fact that female lizards have a greater endoparasite abundance due to variations in food composition between sexes.

A Citation Analysis of Australian Science and Social Science Journals

ABSTRACTThe Journal Citation Reports for both the Science Citation Index and Social Sciences Citation Index for 1991 were used to perform a citation analysis of Australian science and social science journals. It was found that the Australian journals cited overseas journals at a significantly higher rate than they were cited by these journals, and that Australian journals were cited predominantly by other Australian journals. They also showed a high rate of self citation. On the basis of impact factors, the most highly ranked Australian journals were Reproduction Fertility and Development (ranked 858 out of 4 292) for the sciences, and Australian and New Zealand Journal of Psychiatry (ranked 402 of 1 380) for the social sciences.The analyses reported in this article were supported by funding through the Borchardt Library, La Trobe University.
Protective Effects of Eicosapentaenoic Acid on the Glomerular Endothelium via Inhibition of EndMT in Diabetes

Diabetes-induced endothelial pathologies are hypothesized to lead to the progression of diabetic kidney disease (DKD). The endothelial to mesenchymal transition (EndMT) possibly induces fibrosis, leading to glomerulosclerosis in the kidney. Furthermore, this could lead to albuminuria in diabetic nephropathy due to glomerular endothelial dysfunction. Eicosapentaenoic acid (EPA), purified from fish oil, decreases inflammatory cytokine levels in glomerulonephritis. Here, we aimed at finding whether ethyl eicosapentaenoate (EPA-E) exerts renal protective effects via EndMT inhibition. To find out whether EPA inhibits EndMT in vitro, the changes in CD31 expression were studied in cultured mouse endothelial cells. The addition of the conditioned medium from the adipocyte culture significantly decreased the protein levels of CD31, while the addition of EPA-E partially reversed this inhibition. Further, EndMT inhibition by EPA-E treatment might occur via the inhibition of the protein kinase Cβ (PKCβ)/transforming growth factor-β (TGF-β)/plasminogen activator inhibitor-1 (PAI-1) signaling and not via microRNAs. Streptozotocin-induced diabetic mice fed a high-fat diet (60% from fat) exhibited mesangial expansion and albuminuria. Induction of EPA-E ameliorated the mesangial expansion and decreased albuminuria without affecting blood pressure, triglyceride and free fatty acid levels, and intraperitoneal glucose. These findings suggest that EPA-E exerts renal protective effects on endothelial cells, by normalizing EndMT followed by the PKCβ/TGF-β/PAI-1 signaling. Thus, EPA-E has the potential for imparting renal protection by regulating EndMT in DKD.
Effect of pediatric drugs on solubility of restorative materials used in primary teeth

Background: Pleasant tasting syrups have a long history of use in pediatric practice to aid compliance with medication. Pharmaceutical firms sweeten liquid drug preparations with sucrose to increase the palatability which causes dental caries and erosion in children. In pediatric population, the commonly used esthetic restorative materials are glass ionomers, compomers or composites. Hence solubility of dental restorative materials are of considerable clinical importance and cannot be overlooked. Aims and objectives of current study were to evaluate the effect of commonly used pediatric drugs on the surface solubility of pediatric restorative materials.Methods: The study was conducted on 40 disc shaped specimens of GIC and composite immersed in artificial saliva and pediatric drugs, at 370C for 7 days to determine the solubility in pediatric drug formulations. The solubility of the specimens was calculated by a given formula by comparing the initial and final masses of the specimens.Results: In both GIC and Composite groups higher solubility was seen with paracetamol drug formulations. The mean solubility value of GIC was 0.14±0.02 and that of composite was 0.07±0.035, in paracetamol drug formulations.Conclusions: From the above experimental study it can be concluded that the solubility of restorative materials were comparatively higher in pediatric liquid medications with low pH. Among the drugs paracetamol showed increased erosive effects leading to solubility.
Indicators of longitudinal unevenness of roads in the USA

About 25,800 longitudinal profiles of in-service roads in the USA (Long-Term Pavement Performance (LTPP) Program) were evaluated to obtain indicators of the longitudinal unevenness (roughness) of the road surface defined by standards ISO 8608 : 1995 and EN 13036-5 : 2006. Besides the commonly used International Roughness Index (IRI), also parameters of the Power Spectral Density (PSD) were evaluated taking into account not only the whole interval of effectively acting wavelengths, but also its two and three partial sub-bands. Differences between left and right tracks and between Asphalt Concrete (AC) and Portland Cement Concrete (CC) wearing courses were considered. For all the mentioned indicators (21), their Probability Density Functions (PDF) and numerical statistics were estimated.
Decadal Variability of Winter Warm Arctic‐Cold Eurasia Dipole Patterns Modulated by Pacific Decadal Oscillation and Atlantic Multidecadal Oscillation

In recent decades, the winter surface air temperature (SAT) anomaly in the Northern Hemisphere has exhibited a warm Arctic‐cold Eurasia (WACE) dipole pattern and this has undergone significant decadal variation. In this paper, the physical cause of the decadal variability of the WACE pattern is explored, and it is shown to be mediated by the phases of the Pacific Decadal Oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO). Although the negative PDO (PDO−) or positive AMO (AMO+) favors the WACE pattern, the meridional structure of the pattern is significantly influenced by whether PDO− or AMO+ dominates. During PDO− (AMO+) phase, the winter‐mean WACE pattern shows an asymmetric dipole with weak (strong) warm anomaly over the Barents‐Kara Seas or BKS and strong (weak) cold anomaly over central Eurasia or Siberia, which corresponds to Ural blocking (UB) concurring with the negative (positive) phase of North Atlantic Oscillation in a winter‐mean field. The winter asymmetric WACE pattern is more strongly related to PDO− than AMO+. It is further found that an asymmetric sub‐seasonal WACE dipole pattern with strong (weak) warm anomaly over BKS and weak (strong) cold anomaly over Siberia is usually formed during the UB episode due to favored (suppressed) sub‐seasonal downward infrared radiation and turbulent heat flux over BKS during AMO+ (PDO−), which leads to a strong asymmetric dipole of the winter WACE pattern.
Effectiveness of BNT162b2 and mRNA-1273 Second Doses and Boosters for SARS-CoV-2 infection and SARS-CoV-2 Related Hospitalizations: A Statewide Report from the Minnesota Electronic Health Record Consortium

Using vaccine data combined with electronic health records, we report that mRNA boosters provide greater protection than a two-dose regimen against SARS-CoV-2 infection and related hospitalizations. The benefit of a booster was more evident in the elderly and those with comorbidities. These results support the case for COVID-19 boosters.
Location Label Speech Options Improve Robot Operator Performance

Operators increasingly use speech communication to direct robots. Thus, research on how robot operators may most effectively use speech communication is increasingly important. If certain types of speech communication increase performance then it is incumbent on robot designers to produce robots that allow for these types of communication. An experiment was conducted as a follow up to a previous experiment (Cassenti, Kelley, Swoboda, & Patton, 2009) to test whether participants who were given the ability to use certain location labels performed better than those who could only give direction commands (i.e., turn right, move forward). The results indicated that robot performance was improved when participants could direct a robot using location labels. We interpret these results to suggest that robots which are designed to perform indoor navigation have improved performance when participants can use location labels for structural parts of a building (i.e., doors, halls, and rooms with numerical labels). We recommend that the robotic platform used in the present study be developed to recognize these location labels by incorporating visual recognition algorithms and map incorporation skills.
Doppler ultrasound in vitro modeling of turbulence in carotid vascular disease

Turbulence is ubiquitous to many systems in nature, except the human vasculature. Development of turbulence in the human vasculature is an indication of abnormalities and disease. A severely stenosed vessel is one such example. In vitro modeling of common vascular diseases, such as a stenosis, is necessary to develop a better understanding of the fluid dynamics for a characteristic geometry. Doppler ultrasound (DUS) is the only available non-invasive technique for in vivo applications. Using Doppler velocity-derived data, turbulence intensity (TI) can be calculated. We investigate a realistic 70% stenosed bifurcation model in pulsatile flow and the performance of this model for turbulent flow. Blood-mimicking fluid (BMF) was pumped through the model using a flow simulator, which generated pulsatile flow with a mean flow rate of 6 ml/s. Twenty-five cycles of gated DUS data were acquired within regions of laminar and turbulent flow. The data was digitized at 44.1 kHz and analyzed at 79 time-points/cardiac cycle with a 1024-point FFT, producing a 1.33 cm/s velocity resolution. We found BMF to exhibit DUS characteristics similar to blood. We demonstrated the capabilities to generate velocities comparable to that found in the human carotid artery and calculated TI in the case of repetitive pulsatile flow.
Enhanced winter, spring, and summer hydroclimate variability across California from 1940 to 2019

California’s recent hydroclimatic pivots have caused billions of dollars in damages with the potential to become more extreme in the future, even if the mean total precipitation and streamflow do not change. In this study, we compile instrumental precipitation and streamflow records across California to quantify trends in hydroclimatic variability across spatial, temporal, and seasonal domains. We use the 10th and 90th percentiles of the distribution to examine whether any trends in variability are driven primarily by extreme low or high rainfall or streamflow events. Our analysis shows that there is a statistically significant positive trend in precipitation variability that is driven by long‐term increases to the 90th percentile through most of California during winter (January–March), which has been steadily increasing since the mid‐20th century. In contrast, significant positive streamflow trends are seen in winter, spring (April–June), and summer (July–September) and are driven by changes to both the 10th and 90th percentiles. Moreover, we found that there is a decreasing trend in fall (October–December) hydroclimatic variability, particularly over central California, that is related to declining values in the 90th percentile in both precipitation and streamflow. Our results suggest that California’s hydroclimate has been under a continually heightened state of volatility, leaving the state vulnerable to hydroclimatic extremes and elevated risk of associated compound events (floods, landslides, fires). Thus, water resources managers will need to incorporate this increased volatility into their planning for public and agricultural water supply, while being aware of the higher risks for wildfires and floods as well as the disproportionate and lasting impact on vulnerable ecosystem structures.
Genetic profiles of three Cinchona species in Junghuhn Natural Reserve, Indonesia

Cinchona species were widely used as ancient medicines for different diseases because they contain the active component quinine and its derivatives. However, studies on the molecular aspects of cinchona, including its genetic diversity, have not been reported because most previous works focused on the administration of the antimalarial cinchona alkaloid. Quinine is also being tested as alternative compound for the treatment of Covid-19. The Junghuhn Natural Reserve in Indonesia contains three different types of cinchona plants, namely, Cinchona calisaya, Cinchona pubescens, and Cinchona sp. Given that the genetic diversity and kinship of these species have never been studied, collecting data on the cinchona gene pool has become imperative. This study analyzed the genetic diversity of the cinchona species in the Junghuhn Natural Reserve, Indonesia, by using eight RAPD markers, i.e., OPA-2, OPA-9, OPB-02, OPB-03, OPB-04, OPB-05, OPB-7, and OPJ-07, during 2020 at the University of Jenderal Soedirman, Purwokerto-Indonesia. Polymorphic band data were obtained. Then, phenogram analysis was conducted by using UPGMA and maximum parsimony with MEGA7. The RAPD profiles of Cinchona species (C. calisaya, C. pubescent, and Cinchona sp.) revealed polymorphism with different markers, i.e., OPA-2 (90%), OPB-2 (75%), OPB-5 (75%), OPB-3 (66.66%), OPB-4 (66.66%), OPB-7 (66.66%), OPJ-7 (66.66%), and OPA-9 (58.33%) sequentially with total polymorphism (70.62%). C. calisaya was identified as the most distinctive species. UPGMA yielded a coefficient of 0.200 and two distinctive groups: Group I, which comprised C. pubescens and Cinchona sp. with the p-distance value of 0.333, and Group II, which contained C. calisaya. Ixora sp. was treated as an outgroup plant. The topology of the dendrogram was consistent with that of the UPGMA dendrogram. Results may be used for the further exploration of the genetic diversity of cinchona species.
A Fuzzy Best Worst approach to the determination of the importance level of digital supply chain on sustainability

In today's world where the importance of digitalization is increasing day by day, companies to increase their competitiveness have focused on digital supply chain instead of traditional supply chain. In a world where resources are constantly decreasing, the concept of sustainability has become very crucial in every part of life. Digital technologies, on the other hand, have a direct relationship with sustainability. Sustainability has three main dimensions: economic, environmental, and social. Therefore, the aim of this study is to evaluate digital supply chain on 3 basic dimensions of sustainability. For this purpose, Fuzzy Best Worst Method (F-BWM) was used to define the importance level of criteria. Findings reveal that the concept of sustainability in textile firms in Turkey is generally perceived within an economic and environmental area, rather than within a social dimension. This study is very important in putting forward digital technologies which utilizing in supply chain and the impact of the digital supply chain on sustainability.
