The Proposal of Corporate Payout D Modelling

Decisions on a company s profit sharing are the most important financial decisions for both the shareholders as a source of additional income and the company as the source of cash outflow. The net profit can be transferred to the shareholders in the form of dividends or stock repurchases. Due to the fact that for both, dividends and share repurchase, the source of payments is the net profit (either last year profit, or retained profit), it can be assumed that decisions regarding dividend payments and share repurchases are interdependent. Therefore, a very important and so far without an unequivocal solution is the problem of measuring the relationship between decisions on dividend payments and share repurchases (whether to pay out a possibility of interdependence of both forms of corporate payout policy as well as the fact that data describing payout policy are of panel nature and the relationships between the decisions and the determinants may be non-linear, two simultaneous equations second order panel binomial choice model with random specific effects, the parameters of which are estimated in the same way as in the two stage least squares, was suggested for modelling the payout policy. The modelling procedure was verified by the estimation of the model on a balanced panel of 153 companies listed on the Warsaw Stock Exchange over the period 2008 2016 (1,377 observations). The study results show that the proposed procedure enables the selection of appropriate factors determining the decisions on dividends and share repurchases and the assessment of the relationship between them. It takes into the consideration the panel nature of the data and the possibility of heterogeneity and removes the phenomenon of endogeneity in the model, thereby, filling an existing gap in the literature on corporate payout decisions.
Assessment of climate change impact on pulse, oilseed and vegetable crops at Varanasi, India

Decision Support System for Agrotechnology Transfer (DSSAT v4.6.1) was used to study the impact of climate change and variability on productivity of different monsoon (pigeonpea and groundnut) and winter season crops (chickpea, mustard, tomato and potato) at Varanasi. Keeping in view the observed trends in climate variability, productivity of different cash crops were simulated under plausible synthetic climatic scenarios of changes in temperature and carbon dioxide. Productivity of pigeonpea and groundnut in monsoon season and mustard, tomato and potato in winter season decreased with an increase in temperature. Productivity of different pulse, oilseed and vegetable crops increased under expected enhanced CO2 concentrations. Highest productivity decreased in pigeonpea crop (96.0%) in monsoon season and minimum in tomato crop (4.0%) in winter season with an increase of 3.0 °C in temperature above normal. Highest productivity increase in mustard crop (164.0%) in winter season and lowest in pigeonpea crop (33.0%) in monsoon season were simulated under projected enhanced CO2 concentration of 760 ppm. Highest counter-balance in productivity of mustard crop (150%) followed by tomato crop (81%) during winter season and lowest in pigeonpea crop (99%) during monsoon season were simulated when an increase in temperature by 3.0 °C above normal under projected enhanced CO2 concentration of 760 ppm.
Gender differences in peak expiratory flow rate and timed vital capacity by computerized spirometry in medical students

Background: Throughout the human life span, airway behavior and the clinical manifestations of airway disease show gender differences which are related to other factors such as biological and sociocultural factors. Similar studies have been conducted in various parts of India and showed wide variations even within the state with similar socioeconomic and cultural factors. Even physical activity too has influenced pulmonary function tests (PFT). The most of the studies on PFT were carried out in the Southern part of Karnataka and no previous studies on this topic were done in Bidar. Aim and Objectives: The aim of the study was to study the gender differences in peak expiratory flow rate (PEFR) and timed vital capacity among medical students of BRIMS, Bidar. Materials and Methods: After obtaining ethical clearance from institute, the study was conducted on healthy 18–25 years aged 200 males and 200 female undergraduate medical students in Department of Physiology, BRIMS, Bidar. After recording basic physical characteristics, lung parameters that are forced vital capacity (FVC), forced expiratory volume in the 1st s (FEV1), FEV3, and PEFR were recorded using Micro Quark, a PC-based spirometer, connected through serial port (RS232). Statistical analysis was done using independent sample t-test with the help of SPSS 25 version. P < 0.05 was considered the level of significance. Results: Results revealed that there was statistically significant decrease in the mean values of FVC(L), FEV1(L), FEV3(L), and PEFR (L/min) in female subjects compared to male subjects (P < 0.01). Even there was statistical significant decrease in FEV1/FVC ratio in female subjects compared to male subjects (P < 0.05). Conclusion: Our study concluded that the values of FVC, FEV1, FEV3, FEV1/FVC, and PEFR were observed to be higher in male undergraduate subjects when compared with female subjects of BRIMS, Bidar.
Post Intensive Care Tele Pulmonary Rehabilitation in Post-COVID-19: A Case Series

Muscle weakness acquired in intensive care, postintensive care syndrome, psychological dysfunction and changes in body composition are the main reasons cited in Pulmonary Rehabilitation (PR) applications after discharge in cases followed up in the intensive care unit (ICU) due to COVID-19 pneumonia. Although the limitations of face-to-face PR applications during the pandemic have made tele-PR more common, the appropriate patient profile for PR is still unknown. In this case series, video conferencingmediated tele-PR was applied as a hybrid approach and compared with PR in a face-to-face format in five cases referred after ICU. After the initial and final evaluations and the first two exercise sessions were performed in the outpatient PR unit, the program was continued via a video-conferencing method. At the end of the total 18 sessions, a decrease was noted in the perception of dyspnea, and an increase in exercise capacity and muscle strength. A decrease in the severity of COVID-19-related fatigue was also noted.

Hedge Fund Win versus Management Win: Activism Outcome, Governance Impact and Shareholder Value Gains

Using an international sample of 1,750 hedge fund activist engagements from 2000 to 2014, we examine whether these engagements cause improvements in long-term firm performance and shareholder value. Endogeneity is a critical issue in this context since factors that make companies attractive targets for activism may also be the primary drivers of any performance improvement. Once endogeneity is accounted for, we find no evidence to support the view that hedge fund activism leads to long-term shareholder wealth creation. In fact, companies targeted by hedge funds might have experienced even better performance were it not for the activists’ engagements. Further analysis suggests that target firms underperform significantly more when the hedge funds fail in their campaign and incumbent managers prevail. In these cases, the target shareholders experience significantly higher agency costs associated with managerial entrenchment but these costs are alleviated to some extent by increased board independence or CEO. Overall, while HF activism is not great news for target shareholders, what is worse news is that incumbent managers defeat the HF campaign. JEL classification: G32; G38
Fear of COVID-19 among Health Care Workers: Roles of Resilience, Meaning in Life, And Proximity of Working with COVID-19 Patients

Background: While the COVID-19 pandemic has had a detrimental impact on most of the world's population, fear of COVID-19 has especially affected health care workers (HCW) who are on the battlefield with the virus. Yet, the factors that determine the level of fear of COVID-19 among HCWs are still obscure. Methods: A survey whose participants were 705 HCWs including physicians, nurses, administrative and other medical personnel. Multiple regression analysis was implemented to assess the relationship between demographic covariates, psychological variables, and fear of COVID-19. A second survey was conducted following the vaccination program. Results: Resilience, meaning in life, age, gender, and role in hospital (administration) were found to be significant in explaining the variance in fear of COVID-19 after controlling the effect of other predicting variables in the model. Among them, resilience was the most robust predictor for fear of COVID-19, indicating that HCW with higher resilience were less affected by fear of COVID-19. No difference was found in the level of fear of COVID-19 as well as other psychological variables in the second survey conducted after the vaccination phase in Israel. Discussion: The results suggest that among HCWs, those who work closely with patients carrying COVID-19, and those with greater resilience, have had significantly less fear of COVID-19. These findings emphasize the need to enhance resilience in order to reduce the psychological burden of the pandemic as well as other prolonged , stressogenic events among HCWs.
Comparison of pre-PICU and per-PICU interventions, clinical features and neurologic outcomes of motor vehicle collision trauma and other mechanisms of trauma in children

ABSTRACT BACKGROUND: Motor vehicle collisions (MVCs) are the number one cause of death in the pediatric age group. The aim of this study was to determine the differences between MVCs and other trauma mechanisms (OTMs) in patients who were followed up at a pediatric intensive care unit (PICU). METHODS: Data were retrospectively collected for pediatric trauma patients hospitalized at a third level PICU between 2014 and 2018. Patients have been divided into two groups as MVC and OTM. Demographic data, pre-PICU interventions (cardiopulmonary resuscitation, intubation, injury severity scores, time period before intensive care), intensive care interventions (invasive mechanical ventilation, non-invasive mechanical ventilation, need for surgery, type of surgery, need for transfusion, and inotrope therapy) were compared between two groups. Outcomes were evaluated by survival, discharge from hospital, Pediatric Cerebral Performance Category (PCPC) at discharge, tracheotomy presence, and amputation performed. RESULTS: During the 5-year study period, 135 patients were hospitalized for trauma. The injured body regions were the head and neck (61.5%), abdomen and lumbar spine (39.4%), and extremities and pelvis (36.3%). Multiple trauma was mostly seen in the MVC trauma group (p=0.001). The need for invasive mechanical ventilation and inotrope therapy was greater in the MVC group (p=0.002, 0.001 respectively). One hundred and twenty-three patients (91.1%) survived. The mortality rate was higher in the MVC group (p=0.026). The PCPC results were better in the OTM group (p=0.017). CONCLUSION: MVCs lead to more multiple trauma cases than OTMs. Invasive mechanical ventilation, inotropes, and other intensive care interventions were necessary much more often in MVC victims than in OTM patients.
Impact of Farmer Associations on Sales and Crop Diversiﬁcation

Contributing to the growing interest in understanding the impact of farmer cooperatives on rural household welfare, we add new empirical evidence to the current literature and debate. In particular, this study investigates the impact of farmer cooperatives on sales per hectare of land and crop diversification, which have been largely overlooked. We apply the Propensity Score Matching method to the Cambodia Inter-Censal Agricultural Survey 2019 with its very large sample size of 16,000 small-scale producers. Additionally, we perform a robustness check to make sure that our findings are unbiased. Results indicate that Cambodian farmers perceive the cooperatives as a risk-sharing mechanism or knowledge-sharing platform that provides technical know-how to cope with natural calamities. Propensity Score Matching (PSM) outputs, moreover, show a significantly positive impact of participating in the cooperatives on sales and on the crop diversification index. This study thus advocates increasing technical support and implementing policies by the government to help cooperatives thrive and expand.
Modeling consumers ' likelihood to adopt autonomous vehicles based on 1 their peer network 2 3

1 their peer network 2 3 Ishant Sharma, Sabyasachee Mishra* 4 5 Department of Civil Engineering, University of Memphis, Memphis, Tennessee, 38152, United 6 States 7 8 Abstract 9 10 Adoption of connected and autonomous vehicles (CAVs) is viewed as one of the vital factors by 11 public and private agencies as benefits are slowly getting quantified with further advancement in 12 technology. From a wide variety of CAV perception and demand estimation studies, the literature 13 lacks the impact of adoption based on an individual's social network and values. In this paper, we 14 utilize an integrated choice and latent variable model to capture individuals' likelihood to adopt 15 level 4 CAVs based on their social values in their peer network using an institutional survey 16 dataset. The model results suggest that households with high income and frequent car buyers are 17 more likely to adopt CAVs. CAV adoption will have a positive influence on an individual's social 18 values among his peers. The proposed framework can be used to provide useful insights for 19 policymakers to quantify consumers' preferences about CAV adoption based on their social values. 20

Acquisition of the Verb Movement Parameter in French by Adult English Speakers

This paper focuses on a parametric difference between French and English, namely the verb movement parameter. Previous research shows that verb-raising in French causes learnability problems for Anglophone learners. Because of verb raising in French, an adverb may be placed between the verb and its direct object, allowing the subject-verb-adverb-object (S-V-Adv-O) structure. However, the lack of verb movement prohibits the S-V-Adv-O structure in English. The acquisition of verb movement is a welldocumented topic in the second language (L2) acquisition research. However, previous L2 acquisition studies have focused on L2 speakers who are in the initial stage of their L2 acquisition. The present paper focuses on the acquisition of the verb movement parameter by a group of intermediate L2 French speakers whose first language (L1) is English. It also investigates two models, namely the Failed Functional Features Hypothesis (FFFH) and the Full Transfer Full Access Hypothesis (FTFAH). The FFFH predicts that L2 speakers are unable to reset parameters from their L1 values to the L2 settings, as they do not have access to Universal Grammar (UG). On the contrary, the FTFAH suggests that L2 speakers can reset parameters to the target L2 settings due to the full accessibility of UG. The data was collected via three tasks: an acceptability judgment task, a preference task, and a production task. The findings suggest that the L1-English–L2-French speakers had not fully acquired the adverb placement in French. Therefore, the results support the FFFH, as the L1-English–L2-French speakers had not reset parameters from their L1 values to the L2 settings.
ROLE OF THE BIOMARKERS PRESEPSIN AND PROCALCITONIN IN THE EARLY DETECTION OF SEPSIS AND RISK STRATIFICATION IN INTENSIVE CARE PATIENTS

Sepsis is one of the main realities in Intensive Care, in terms of frequency and significance. Therefore, an early detection is essential. The objective of this observational study, carried out within the multispecialty department of Anesthesia and Intensive Care of the "G. Rodolico" Polyclinic Hospital of Catania, is the evaluation of the diagnostic role that a marker of sepsis, such as Presepsin, also has with discriminating power and risk stratification, in comparison with the data of another biomarker of infection, such as Procalcitonin. The study was conducted on 26 patients admitted in 4 months, from 28 May 2020 to 28 September 2020, at multispecialty department of Anesthesia and Intensive Care of the "G.Rodolico" Polyclinic Hospital of Catania. The clinical data for each patient were obtained from the daily assessment, supplemented by the data drawn from the consultation of individual clinical records. Patients transited to Intensive Care aged > 18 years and hospitalization period of at least 48 hours were included. Our data seems to give higher predictive value for presepsin, despite the small number of patients tested. This also allows the evaluation on the possible evolution of the clinical picture, with prognosis prediction favorable for lower values and unfavourable for considerably high values.
Extractive composition and bioactivity of Uncaria acida and Uncaria glabrata wood

Uncaria acida (red bajakah) and Uncaria glabrata (white bajakah) belong to the liana woody species. Both are naturally cultivated in Indonesia, particularly in Kalimantan (Borneo) island. This study, aims to investigate the extractive composition of U. acida and U. glabrata wood considering that extracts from different lianas usually are used as anticancer drugs (breast cancer). The phenolic, alkaloid, and saponin contents were measured by colorimetric and GC-MS methods, while the antioxidant, antifungal, and cytotoxicity were investigated using DPPH, Phanerochaete chrysosporium (white-rot), and brine shrimp lethality tests, respectively. The results showed that the total tannins, phenols, and saponins in U. acida were higher compared to U. glabrata, while the total flavonoids, alkaloids, polysaccharides, and antioxidant activity was lower. The GC-MS analysis indicated the presence of aromatic compounds, fatty acids, and triterpenoids in both species. High concentration of phenols, alkaloids, saponins, fatty acids, and steroids are known to provide support in terms of antioxidant, cytotoxicity, and antifungal activities.
Vibration Analysis of Tapered Beam

Beams are very common types of structural components and it can be classified according to their geometric configuration as uniform or taper and slender or thick. If practically analyzed, the non-uniform beams provide a better distribution of mass and strength than uniform beams and can meet special functional requirements in architecture, aeronautics, robotics, and other innovative engineering applications. Design of such structures is important to resist dynamic forces, such as wind and earthquakes. It requires the basic knowledge of natural frequencies and mode shapes of those structures. In this research work, the equation of motion of a double tapered cantilever Euler beam is derived to find out the natural frequencies of the structure. Finite element formulation has been done by using Weighted residual and Galerkin’s method. Natural frequencies and mode shapes are obtained for different taper ratios. The effect of taper ratio on natural frequencies and mode shapes are evaluated and compared.
Neuromusculoskeletal interfacing of lower limb prostheses

The method of bone-anchored attachment of limb prostheses via a percutaneous skeletal extension was developed to circumvent commonly reported problems associated with the conventional method of socket attachment. In addition to the direct structural connection, the percutaneous implant may serve as a conduit for bidirectional communication between muscles and nerves within the residual limb and the prosthesis. Implanted electrodes recording myoelectric activity within the residual limb can be used to infer the user’s movement intent and may thus be used to provide intuitive control of the prosthesis in real time. Sensory feedback from the prosthesis can be provided back to the user by neurostimulation via implanted neural electrodes, thus closing the control loop. Together the skeletal, neural, and muscular interfaces form a neuromusculoskeletal interface. This technology is currently being evaluated in a clinical trial on individuals with upper limb amputation, but it has not yet been used in the lower limb. The aim of this thesis has been to translate the concept of neuromusculoskeletal interfacing to the lower limb. An additional aim has been to reduce the limitations on high impact activities, that exist on current available systems for bone-anchored attachment of limb prostheses. To achieve these aims, a new design of the neuromusculoskeletal interface was developed where the structural capacity was increased with respect to current versions of the implant system to accommodate increased loads for highly active usage by individuals with lower limb amputation. In order to set adequate design requirements, investigations were conducted to determine the load exposure of bone-anchored implant systems during a number of loadbearing activities. Structural verification of the neuromusculoskeletal interface has been performed using numerical simulations as well as physical testing in static and dynamic conditions. The first steps towards clinical implementation of the lower limb neuromusculoskeletal interface have been taken by the development of a clinical research protocol that has been approved by the Swedish Ethical Review Authority.
