Micro-behavioral building blocks of effective leadership, followership and team interaction

Both leadership and team research are flourishing academic areas. However, most studies have examined leader behavior and team interaction based on aggregated perceptual recall ratings. Important leadership theories, such as the transformational-transactional model, and team phenomena have been investigated mainly on the basis of static behavioral survey studies. More and more leadership and team scholars question whether these examinations yield insights into the subtleties of real-time micro-behaviors and interactions between effective leaders and their followers. The aim of this PhD dissertation is, therefore, to (1) show how a host of micro-behaviors of leaders and followers are related with enhanced effectiveness, and (2) identify effective social dynamics between leaders and followers in teams. A blend of advanced methods, tools and techniques (including quantitative video-capture and -coding as well as physiological data collection) were used that resulted in new insights into how effective leaders and their followers interact.
Effects of Early Warning Score (EWS) Tutorial Simulation on Nurses' Knowledge and Clinical Performance

Background: The Early Warning Score (EWS) system has been recommended for early identification tool of deterioration. However, its implementation has not been optimal; one of which is due to the low level of knowledge and understanding of EWS among nurses. Purpose : This study aimed to determine the effects of EWS tutorial simulation on nurses’ knowledge and clinical performance. Methods : This study employed a pretest posttest quasi-experimental design with a control group. Purposive sampling was used to recruit the samples of 42 respondents each in the intervention group and control group. The data were collected using the questionnaires to measure the knowledge and clinical performance, and analyzed using Chi square, Wilcoxon and Mann-Whitney tests. Results : The results showed that there were differences in the pre-test and post-test of knowledge and clinical performance in the intervention group and control group (p<0.001). There was also a significant difference in clinical performance between the intervention group and the control group (p<0.001). However, no significant difference in knowledge was found between. Conclusions : Tutorial simulation of EWS had an effect on increasing nurses’ clinical performance. Although there was no significant difference in knowledge between the intervention group and the control group, but the intervention group showed a better value than the control group. EWS tutorial simulation can be used as one of the training methods to increase nurses' knowledge and clinical performance in EWS.
Estimation the Serum Levels of Endothelin-1, and Nitric Oxide and Its Relation to Occurrence of Intradialytic Hypertension among Individuals Receiving Maintenance Hemodialysis

Background: Intradialytic hypertension is a common problem observed in patients on maintenance hemodialysis and considered as an independent predictor of adverse clinical outcomes. Aim of the work: estimation the serum levels of endothelin-1, and nitric oxide and its relation to occurrence of intradialytic hypertension in patients on maintenance hemodialysis. Methodology: the study is a case control study included 60 patients with end stage chronic renal disease (ESRD) on maintenance hemodialysis, selected from Nephrology Units of Al-Azhar University hospital New Damietta, Kafr Saad and Elzarka General Hospitals during the period from Feb. 2015 to March 2017. They were divided into two groups according to the presence of intradialytic hypertension. Group A: 30 patients with intradialytic hypertension (IHD). Group B: 30 patients without intradialytic hypertension (IHD), All patients were submitted to full history taking and clinical examination; laboratory investigations included routine investigations and estimation of endothelin-1 and nitric oxide before and after dialysis. Results: the serum level of endothelin-1 before dialysis ranged from 2.3 (ng/ml) to 42 (ng/ml) and there was statistically significant increased in group A in comparison to group B and After dialysis, there was statistically significant increased (49.66±21.92) in group A in comparison to group B (17.66±8.36). Before dialysis, nitric oxide ranged from 5.77(µmol/ml) to 95.60(µmol/ml) with a mean of 20.53±17.83 with statistically significant decreased (14.60±6.15) in group A in comparison to group B (26.46±23.15). On the other hand, after dialysis, it ranged from 3.02 to 91.07 with a mean of 11.33±16.18 and there was statistically non significant difference between both groups. Conclusion: Intradialytic hemodynamic changes is a complex interplay of endothelin-1, and endothelial function. endothelin-1 and nitric oxide are strongly involved in the occurrence of intradialytic hypertension Among Individuals Receiving Maintenance Hemodialysis.
Sleep quality and the problems in smokers and nonsmokers: a comparative study

ABSTRACT Objective: Sleep quality and risk of sleep apnea in smokers and nonsmokers living in Kermanshah province-Iran were compared. Methods: Based on the statistics available at Kermanshah Health Center, 50 different clusters of the city were selected randomly. Then, eight to 13 subjects in age range of 20 to 60 were selected from each cluster according to the inclusion criteria of the study (n = 390, two groups of 195 subjects). The subjects were assessed using the Pittsburgh sleep quality index (PSQI) and the Berlin questionnaire (BQ). Results: There was a significant difference in terms of mental sleep quality, sleep problems, taking sleeping pills, and low performance throughout the day between the smokers and nonsmokers (P < .05). Sleep quality was not good in smokers, and they had a significantly higher snoring and drowsiness in comparison with nonsmokers (P < .05). Furthermore, sleep apnea was significantly higher in the smokers (P < .05). The findings also revealed that consuming more than 10 cigarettes in a day reduced sleep quality and increased obstructive sleep apnea (P < .05). Conclusion: The results showed that cigarette smoking leads to respiratory problems and lower sleep quality.
Optimal trajectory planning and predictive control for cinematographic flight plans with quadrotors

Cette these s'interesse a la realisation autonome de plans de vol cinematographiques par un quadrotor equipe d'une camera. Ces plans de vol consistent en une serie de points de passage a rejoindre successivement, en adoptant diverses methodes de prise de vue et en respectant des references de vitesses ainsi que des couloirs de vols. Une etude approfondie de la dynamique du quadrotor est tout d'abord proposee et utilisee pour construire un modele linearise du drone autour de l'equilibre de vol stationnaire. L'analyse de ce modele lineaire permet de mettre en evidence l'impact de l'inertie des rotors du drone dans sa dynamique, notamment l'apparition d'un comportement a non minimum de phase en roulis ou tangage, lorsque les moteurs sont inclines. Dans un second temps, deux algorithmes de generation de trajectoires lisses, faisables et adaptees a la cinematographie sont proposes. La faisabilite de la trajectoire est garantie par le respect de contraintes sur ses derivees temporelle, adaptees pour la cinematographie et obtenue grâce a l'etude du modele non lineaire du drone. Le premier repose sur une optimisation bi-niveaux d'une trajectoire polynomiale par morceaux, dans le but de trouver la plus rapide des trajectoires a minimum de jerk permettant d'accomplir la mission. Le second algorithme consiste en la generation de trajectoires B-spline non-uniformes a duree minimale. Pour les deux solutions, une etude de l’initialisation du probleme d'optimisation est presentee, de meme qu'une analyse de leurs avantages et limitations. Pour ce faire, elles sont notamment confrontees a des simulations et vols exterieurs. Enfin, une loi de commande predictive est proposee pour asservir les mouvements de la camera embarquee de maniere douce et precise.
DECISION-MAKING SPECIALITIES IN THE LIGHT OF CORPORATE SOCIAL RESPONSIBILITY

Company decision-makers increasingly have to confront with the expectations of their closer or extended community, also that of their environment in connection with the consequences of their business-decisions. On the other hand, they must represent the interests of their proprietors and must also sustain profitable economy. The author reviews those factors which have a significant impact on socially responsible decision-making process, concerning the decision-makers, the company and the outer environment. The author answers to the question of what the specialities of such decisions are and in what direction the attitude of economic entities develop, concerning socially responsible operation. The author proved that corporate social responsibility (CSR in short form) manifests itself in a growing and expanding measure in the activities of corporations and business structures, on the one hand, as an expectation in connection with their courses, on the other hand, such a factor if fails, can make long-term competitiveness worse. Decisions related to CSR are strategic decisions, so they are made at the highest level. The personality, leadership style and self-assessment of the decision maker play a decisive role in the process of the influence of external expectations regarding CSR on organizational decisions. In addition, the size of the company, the regional location, the surrounding national culture, the social system and traditions also have a significant influence on socially responsible decisions. The described article/presentation/study was carried out as part of the EFOP-3.6. 1-16-00011 “Younger and Renewing University – Innovative Knowledge City – institutional development of the University of Miskolc aiming at intelligent specialisation” project implemented in the framework of the Szechenyi 2020 program. The realization of this project is supported by the European Union, co-financed by the European Social Fund.
Admissible Hybrid Z-Contractions in b-Metric Spaces

In this manuscript, we introduce a new notion, admissible hybrid Z -contraction that unifies several nonlinear and linear contractions in the set-up of a b-metric space. In our main theorem, we discuss the existence and uniqueness result of such mappings in the context of complete b-metric space. The given result not only unifies the several existing results in the literature, but also extends and improves them. We express some consequences of our main theorem by using variant examples of simulation functions. As applications, the well-posedness and the Ulam–Hyers stability of the fixed point problem are also studied.
An Experimental Vignette Study on the Attractiveness of Ownership-Based Carsharing Communities: A Social Capital Theory Perspective

Although the sharing economy is rapidly growing, it is still in its infancy. One of the key challenges is successfully expanding the number of users joining the sharing economy. Our research empirically assesses which organizational form is most successful in attracting new consumers to the sharing organizations that are co-owned by their users. The structure and scope of these sharing communities may differ substantially: while closed sharing communities are neighborhood based, open sharing communities establish broad communities without geographical boundaries. Building on social capital theory, we find that open sharing communities are more attractive than closed sharing communities because they foster trust and alleviate perceived scarcity risk. Yet, important boundary conditions exist. While a social and environmental orientation increases the likelihood to join open sharing communities, this is not the case for closed sharing organizations. These results highlight the value of examining distinct organizational forms of sharing organizations.
Effects of ceramic particle size on cell attachment and viability in polyurethane-based bone adhesive composites

Millions of people require bone injury treatment and there have been many methods suggested for the stabilization of bone fractures. The need for the development of new methods is obvious since current stabilization methods are inadequate. Here, we described the development of polyurethane-based bone adhesives composites containing β-tricalcium phosphate ceramics in different sizes and ratios. To characterize the proposed materials, Fourier transform infrared spectroscopy, hydrogen-nuclear magnetic resonance, differential scanning calorimetry analyses together with scanning electron microscopy observations, and micro-computerized tomography imaging were examined. Furthermore, in vitro performance of the produced materials was tested by using MG63 human osteosarcoma cell line, and an ex vivo modeling study was conducted to test the mechanical performance of resulting materials using bovine rib bone. All materials were exhibited high porosity (above 90%) and homogeneous distribution of ceramic particles. Polyurethane scaffolds containing 40% (w/w) 1–2 mm β-tricalcium phosphate were shown the highest compressive strength as 1.34 ± 0.10 MPa. In addition, 85.75% cell viability was recorded according to the cytotoxicity analysis and also the cell proliferation was found highest in the same group. Taken into account the obtained results, the prepared polyurethane-based bone adhesive materials containing ceramics has a great potential to transform into a final product and meet a clinically significant medical need.
Low-dose ethanol produces mixed effects on cortico-hippocampal theta rhythms and modifies hippocampal theta frequency through multiple mechanisms

Ethanol is one of the most widely used drugs – with many psychoactive effects, including anxiolysis. The deleterious effects on brain function and general health of chronic and high-level ethanol use are well-studied. However, the neurophysiology of acute low dose ethanol has not been systematically investigated. Here, we examined the effects of low dose (0.25 and 0.5 g/kg) ethanol on midline (prefrontal, cingulate and retrosplenial) cortical and hippocampal theta oscillations in freely moving rats. We also tested low dose ethanol on reticular-elicited and running-elicited hippocampal theta frequency and assessed the linear relationship of theta frequency to stimulation intensity and running speed, respectively. Low dose ethanol had mixed effects on cortical theta oscillations. It most reliably reduced theta frequency, produced a weak inverted-U effect on theta power, and had no detectable effect on cortico-hippocampal theta coherence. Ethanol dose-dependently decreased the y-intercept of the speed-theta frequency function without affecting the slope, but decreased the slope of the stimulation intensity-theta frequency function without affecting the y-intercept; thus decreasing theta frequency in both cases but through different mechanisms. We conclude low dose ethanol has weak but detectable effects on cortical and hippocampal theta oscillations. These effects may underlie positive cognitive and behavioural outcomes reported in the literature using low dose ethanol. The double dissociation of slope and y-intercept specific changes relating to different methods of hippocampal theta elicitation suggests that multiple mechanisms contribute to anxiolytic effects on theta and so hippocampal function.
The proximity filter: the effect of distance on media coverage of the Christchurch mosque attacks

ABSTRACT The intense media coverage in New Zealand and Australia of the Christchurch mosque attacks exhibited significant disparity in editorial decision-making between the two countries. This research interrogates the different approaches taken in newsrooms and how these differences were manifested in broadcasts and publications. New Zealand media were focused largely on empathetic coverage of victims and resisted the alleged gunman's attempts to publicise his cause while their Australian counterparts showed no such reluctance and ran extended coverage of the alleged perpetrator, along with material ruled objectionable in New Zealand. It finds the editorial focus in each case exhibits the effect of proximity, identified in literature on empirical ethical decision-making as a factor in applied ethicality. The authors conclude that a proximity filter was used by New Zealand media who identified the victims as part of their own community, but the events of 15 March 2019 were seen as ‘foreign’ by Australian journalists who used perceived distance as justification for extremely graphic content.
European Stroke Organisation (ESO) guidelines on glycaemia management in acute stroke

Background Hyperglycaemia is a frequent complication in acute stroke that has been shown to be independently associated with larger infarct size, haematoma growth, poor clinical outcome and mortality. This Guideline Document presents the European Stroke Organisation (ESO) Guidelines for the management of blood glucose levels in patients with acute ischemic or haemorrhagic stroke. Methods The working group identified related questions and developed its recommendations based on evidence from randomised controlled trials following the standard operating procedure of the ESO. This Guideline Document was reviewed and approved by the European Stroke Organisation Guidelines Committee and the European Stroke Organisation Executive Committee. Results We found low-quality evidence from clinical trials in ischemic or haemorrhagic stroke exploring the use of intravenous insulin aimed to achieve a tight glycaemic control with different glucose level targets and several other sources of heterogeneity. None of these trials neither the meta-analysis of them have demonstrated any significant benefit of tight glycaemic control with intravenous insulin in acute ischemic or haemorrhagic stroke patients on functional outcome or in survival and they have shown an increased risk for hypoglycaemia. Conclusions We suggest against the routine use of tight glycaemic control with intravenous insulin as a means to improve outcomes. The currently available data about the management of glycaemia in patients with acute stroke are limited and the strengths of the recommendations are therefore weak. Nevertheless, this does not prevent that hyperglycaemia in acute stroke patients could be treated as any other hospitalised patient.
Do Opioids Help Injured Workers Recover and Get Back to Work? The Impact of Opioid Prescriptions on Duration of Temporary Disability

We estimate the effect of opioid prescriptions on the duration of temporary disability benefits among workers with work-related low back injuries. We use local opioid prescribing patterns to construct an instrumental variable that generates variation in opioid prescriptions but is arguably unrelated to injury severity or other factors directly affecting disability duration. Local prescribing patterns have a strong relationship with whether injured workers receive opioid prescriptions, including longer-term prescriptions. We find that more longer-term opioid prescribing leads to considerably longer duration of temporary disability, but there is little effect of a small number of opioid prescriptions over a short period of time.
The Presence of Bristlemouth, Gonostoma denudatum (Rafinesque 1810), From the Coast of Northern Cyprus (Northeastern Mediterranean)

Gonostoma denudatum belonging to Gonostomatidae family are small fishes living in deep-sea around Atlantic and Mediterranean. They are vital species for plastic accumulation because they can be available in all depths of the water column during the day. In this study, it was aimed to present the recent record of G. denudatum , which captured from North Cyprus in May 2018. The total length of the specimen, which obtained from a depth of between 420 and 640 m, is 12.8 cm. Its photograph was taken and the catalogue number (MEUFC-19-11-108) was given. Morphometric characteristics were measured and calculated. The specimen is stored in the Museum of the Systematic, Faculty of Fisheries, Mersin University.
Factors behind the changes in income distribution in the Baltics: income, policy, demography

ABSTRACT This article aims at disentangling the factors behind changes in income inequality and relative poverty in the Baltic states. An evaluation of income, policy, and demographic effects was based on counterfactual scenarios constructed using tax-benefit microsimulation and reweighting techniques. Decomposition showed that income and policy effects were dominant for changes in inequality and relative poverty. The policy effects were inequality- and poverty-reducing after EU accession and before the 2008 financial crisis and as a whole. The income effects for the same periods were inequality- and poverty-increasing. Despite rapid demographic changes, the demographic effect on income inequality and relative poverty was marginal.
Psychological distress, job satisfaction and work engagement: a cross-sectional mediation study with a sample of Palestinian teachers

ABSTRACT The aim of the present study was to evaluate the relationship between psychological distress and job satisfaction in a sample of Palestinian in-service primary and lower secondary teachers (N = 380). Specifically, we cross-sectionally tested the hypothesis that the association between teachers’ job satisfaction and psychological distress would be fully mediated by their levels of work engagement. Participants completed the Arabic versions of the Teacher Job Satisfaction Scale (TJSS-9), General Health Questionnaire (GHQ-12) and Utrecht Work Engagement Short-form scale (UWE-SF). As is conventional in mediation studies, the data were analysed using structural equation modelling and decomposition of direct and indirect effects. The moderate positive relationship identified between job satisfaction and psychological distress was fully mediated by work engagement (F = 17.05, p < .001, R2 = .16). This finding suggests that in order to reduce the effect of low job satisfaction on teachers’ psychological distress, organisational policies and practices should include a focus on enhancing their level of engagement.
Spatial Shift of Greenland Moisture Sources Related to Enhanced Arctic Warming

Understanding the atmospheric moisture budget of Greenland is critical for predicting future Greenland climate. However, past attempts to quantify the provenance of Greenland precipitation have been limited to certain seasons. Here we present an analysis of Greenland moisture sources using water tracers in the Goddard Institute for Space Studies climate model, which can provide source estimates for all time periods. The North Atlantic is found to be the dominant moisture source, except during summer when continental sources increase substantially. The variability is also found to be partially correlated with the Greenland Blocking Index. The key finding, however, is a long‐term trend in the moisture source location for Northwest Greenland, with an increase in more locally sourced moisture over time during nonsummer months. This is at least partially related to sea ice loss in the Baffin Bay region, along with a larger increase in sea surface temperatures for the region relative to other locales.
