CEO turnover and abnormal return: effects of the intensity of news disclosure in economic jornals

abnormal returns and CEO turnover motivations disclosures intensity based on the Efficient-Market Hypothesis (EMH) in its semi-strong form. Design/methodology/approach: A panel data of 65 events publicly traded Brazilian companies that have a Pension Fund among their shareholders, between 2010 and 2014 were used. Applying the Event Study methodology, the ordinary least-squares (OLS) multiple regression analysis was used to calculate the abnormal returns. The CEO turnover data were manually collected and systematically crosschecked, and content analysis were employed to identify its motivations. Spearman’s correlation measured the relation between motivation disclosure intensity and the abnormal returns. Findings: Results reveal a positive and statistically significance relationship between the abnormal return and the intensity of news reporting on CEO turnover. Practical Implications : The study it allows to understand whether the disclosure intensity of the CEOs turnover motivations affects the magnitude of the abnormal returns in firms of which the Pension Funds participate in the capital. Social Implications : The findings have one important implications in firms of which the Pension Funds participate in the capital. It makes possible to assess the Brazilian market behavior in the event of CEO's changing, as sophisticated and regulated institutional investors. Originality/Value: This study extended to disclosure intensity and returns literature by offering new evidence on the effect of CEO turnover motivations disclosures intensity on the market abnormal returns for Brazilian firms. Keywords: CEO turnover. Returns. Intensity of disclosure.
The effect of social deprivation and gender on self-efficacy beliefs about the postsecondary transition

Introduction. High school students’ self-efficacy beliefs about their ability to successfully obtain a first postsecondary destination in employment, education or training, and the learning sources of these beliefs were examined. Method. Factor analysis of an inventory administered to 1044 high school students (573 males and 471 females) who attended six urban schools identified five factors. Results. ANOVA indicated that students living in areas of higher deprivation reported significantly lower levels of positive postsecondary destination self-efficacy belief, and less experience of vicarious career success. Males reported less personal experience of career success than females but higher levels of positive postsecondary destination self-efficacy belief (particularly at higher levels of deprivation). Males reported greater experience of positive career-related emotional arousal. Discussion and Conclusion . These results may contribute to an explanation of why failure to obtain a positive postsecondary destination is more prevalent in young people living in areas of greater social deprivation, and in males rather than females. The implications for practice, policy and future research are discussed.
Ventilation design of industrial premises through CFD modelling

This work investigates a general ventilation system for reducing the health hazard in industrial premises. Several tests carried out in a laboratory mock-up have been used to validate the reliability of a general-purpose computational fluid dynamic model. The same model has been also used to compare the efficiency of different ventilation systems. This clearly indicated the different health hazard related to each configuration, thus allowing one to identify the configuration leading to the lower contamination in the breathing zone. On etudie dans ce travail un systeme de ventilation geneal en vue de reduire les risques de sante en milieu industriel. Plusieurs essais ont ete realises a l'aide d'une maquette de laboratoire afin de valider la fiabilite d'un programme de simulation d'ecoulements de fluides. On a utilise ce meme modele pour comparer l'efficacite de differents systemes de ventilation. Ces essais indiquent les differents risques encourus selon chaque configuration, permettant ainsi de determiner celle qui presente le plus faible risque de contamination dans la zone de respiration.
Blending Probability and Nonprobability Samples with Applications to a Survey of Military Caregivers

Probability samples are the preferred method for providing inferences that are generalizable to a larger population. However, in many cases, this approach is unlikely to yield a sample size large enough to produce precise inferences. Our goal here is to improve the efficiency of inferences from a probability sample by combining (or blending) it with a nonprobability sample, which is (by itself) potentially fraught with selection biases that would compromise the generalizability of results. We develop novel methods of statistical weighting that may be used for this purpose. Specifically, we make a distinction between weights that can be used to make the two samples representative of the population individually (disjoint blending) and those that make only the combined sample representative (simultaneous blending). Our focus is on weights constructed using propensity scores, but consideration is also given to calibration weighting. We include simulation studies that, among other illustrations, show the gain in precision provided by the convenience sample is lower in circumstances where the outcome is strongly related to the auxiliary variables used to align the samples. Motivating the exposition is a survey of military caregivers; our interest is focused on unpaid caregivers of wounded, ill, or injured US servicemembers and veterans who served following September 11, 2001. Our work serves not only to illustrate the proper execution of blending but also to caution the reader with respect to its dangers, as invoking a nonprobability sample may not yield substantial improvements in precision when assumptions are valid and may induce biases in the event that they are not.
Developing instructional materials on mathematics logical thinking through the Indonesian realistic mathematics education approach

Instructional materials are one of the essential parts to support the learning process becomes more exciting and meaningful. However, teachers do not yet give more attention to these parts, so that the learning process becomes uninteresting and boring. Therefore, this research aims to produce the instructional materials for the logical thinking of mathematics ability based on Indonesian Realistic Mathematics Education for junior high school students for Grade 8, which is valid and practical. This research used a design research method with the type of development study conducted in two stages, namely preliminary design and formative evaluation, including self-evaluation, prototyping (expert reviews, one-to-one, and small groups) field tests—the research conducted at junior high school. For research subjects, students of class VIII B of junior high school are 29 students. The techniques of data collection used are documentation, walkthrough, interviews, and test. The research data are quantitatively and qualitatively analyzed. The results of data analysis known that this research produces the logical thinking of mathematics for instructional materials based on Indonesian Realistic Mathematics Education on the content of linear equations of two variables that are valid, practical, and have potential effects. In this case, mathematics instructional materials in students' worksheets based on Indonesian Realistic Mathematics Education have been content valid, constructive, and language from expert validation at the expert review stage. In contrast, the mathematics student worksheets based on Indonesian Realistic Mathematics Education have been practically obtained from revisions results of one-to-one and small group. Furthermore, the prototype of instructional materials in the form of student worksheets has potential effects to improve the logical thinking of mathematics ability for students.
The Poisson Link between Internal Wave and Dissipation Scales in the Thermocline. Part II: Internal Waves, Overturns, and the Energy Cascade

The irregular nature of vertical profiles of density in the thermocline appears well described by a Poisson process over vertical scales 2–200 m. To what extent does this view of the thermocline conflict with established models of the internal wavefield? Can a one-parameter Poisson subrange be inserted between the larger-scale wavefield and the microscale field of intermittent turbulent dissipation, both of which require many parameters for their specification? It is seen that a small modification to the Poisson vertical correlation function converts it to the corresponding correlation function of the Garrett–Munk (GM) internal wave spectral model. The linear scaling relations and vertical wavenumber dependencies of the GM model are maintained provided the Poisson constant κ0 is equated with the ratio of twice the displacement variance to the vertical correlation scale of the wavefield. Awareness of this Poisson wavefield relation enables higher-order strain statistics to be determined directly from the strain spectrum. Using observations from across the Pacific Ocean, the average Thorpe scale of individual overturning events is found to be nearly equal to the inverse of κ0, the metric of background thermocline distortion. If the fractional occurrence of overturning ϕ is introduced as an additional parameter, a Poisson version of the Gregg–Henyey relationship can be derived. The Poisson constant, buoyancy frequency, and ϕ combine to create a complete parameterization of energy transfer from internal wave scales through the Poisson subrange to dissipation. An awareness of the underlying Poisson structure of the thermocline will hopefully facilitate further improvement in both internal wave spectral models and ocean mixing parameterizations.
Do CE mandates impact the number of CE providers and licensing board complaints? A longitudinal look

ABSTRACT With few exceptions, the effectiveness of continuing education (CE) mandates has been measured by self-report assessments of the professional psychologists who fulfill them. The present investigation provided a longitudinal look at the number of approved CE providers and the incidence of licensing board complaints across a succession of two-year cycles prior to, and following, the 2012 implementation of CE mandates in the State of Illinois. Findings showed a substantial increase in the number of CE providers across that time, though no significant change in the incidence of licensing board complaints, suggesting that the increased availability of CE did not translate into lower complaint rates. Possible reasons for these findings are noted, and recommendations for future work are detailed in support of an evidence-based approach to CE that better articulates and aligns its objectives with its outcomes in an era of renewed accountability in the health professions.
Macitentan in infants and children with pulmonary hypertensive vascular disease. Feasibility, tolerability and practical issues – a single-centre experience

Macitentan is a safe and effective substance for treatment of adults with pulmonary arterial hypertension. Data on its use in paediatric patients are limited. In this single-centre prospective study, we report on our experience with macitentan in children focusing on applicability and practical aspects. Between December 2014 and July 2018, macitentan was introduced to paediatric patients according to a dosing protocol adjusted to body weight. Blood pressure, heart rate, saturation and clinical symptoms were recorded daily during introduction. Liver function parameters and haemoglobin levels were measured at baseline, four weeks and three months after initiation and after one year of treatment. Twenty-four patients (14 male, 10 female) were enrolled for treatment with macitentan. The mean age was 10.7 ± 7.6 years (range: 0.1 year–23 years). Fifteen out of 24 patients were World Health Organization functional class (FC) II, 7 patients in FC III and 2 patients in FC IV. Twenty out of 24 patients (83%) received additional advanced therapy with sildenafil and/or prostacyclines. We had two early discontinuations because of clinical relevant oedema. In the remaining 22 patients, macitentan was well tolerated. Liver function parameters and blood count levels remained stable during the observational time. The introduction of macitentan was feasible and mostly well tolerated in paediatric patients. Special attention should be paid to oedema during introduction of the drug. To the best of our knowledge, this is the first study to report on its applicability in infants and children. However, larger prospective trials are warranted to verify these preliminary findings.
Quantifying recycled moisture fraction in precipitation of an arid region using deuterium excess

ABSTRACT Terrestrial moisture recycling by evapotranspiration has recently been recognised as an important source of precipitation that can be characterised by its isotopic composition. Up to now, this isotope technique has mainly been applied to moisture recycling in some humid regions, including Brazil, Great Lakes in North America and the European Alps. In arid and semi-arid regions, the contribution of transpiration by plants to local moisture recycling can be small, so that evaporation by bare soil and surface water bodies dominates. Recognising that the deuterium excess (d-excess) of evaporated moisture is significantly different from that of the original water, we made an attempt to use this isotopic parameter for estimating moisture recycling in the semi-arid region of Eastern Tianshan, China. We measured the d-excess of samples taken from individual precipitation events during a hydrological year from 2003 to 2004 at two Tianshan mountain stations, and we used long-term monthly average values of the d-excess for the station Urumqi, which are available from the International Atomic Energy Agency–World Meteorological Organization (IAEA–WMO) Global Network of Isotopes in Precipitation (GNIP). Since apart from recycling of moisture from the ground, sub-cloud evaporation of falling raindrops also affects the d-excess of precipitation, the measured values had to be corrected for this evaporation effect. For the selected stations, the sub-cloud evaporation was found to change between 0.1 and 3.8%, and the d-excess decreased linearly with increasing sub-cloud evaporation at about 1.1‰ per 1% change of sub-cloud evaporation. Assuming simple mixing between advected and recycled moisture, the recycled fraction in precipitation has been estimated to be less than 2.0±0.6% for the Tianshan mountain stations and reach values up to 15.0±0.7% in the Urumqi region. The article includes a discussion of these findings in the context of water cycling in the studied region.
Prediction of vessel propulsion power from machine learning models based on synchronized AIS-, ship performance measurements and ECMWF weather data

In this paper, AIS (Automatic Identification System), ship performance measurement and ECMWF (European Centre for Medium-Range Weather Forecasts) weather data were synchronized as a complete dataset. Detailed processing steps and methods are introduced which can be used as best practice for future related studies. All the data preparation was processed on a spark cluster. The optimization and turning of cluster performance will also be introduced. The synchronized dataset was adapted to train different machine learning models to predict ship propulsion power. The dataset includes 228 container vessels covering a time scale of 50 months. The performance of deep learning models with different architecture was compared and discussed. Compared to previous paper [1] in the same project, this paper is an extended scenario which combines the data adapted in scenario 1 and 2. The analysis of the models’ performance in different scenarios was discussed. More features were included in scenario 3 (this study). Hence, the best performing model from scenario 3 has more complex structure compared to scenario 1 and 2. The overall absolute R2 score for test data is slightly lower than scenario 2. However, the performance for individual ships (relative R2 score) is much better. This means, models that consider more features (operation, ship characters and environment) are beneficial for individual analysis. For general fleet or wide scope analysis, models that require less data and fewer features are better.
JrbHLH Gene Family: Genome-Wide Identification
and Transcriptional Expression in Persian Walnut
(Juglans regia L.)

In plants, the basic helix-loop-helix (bHLH) transcription factors play key roles in diverse biological processes. Genome-wide comprehensive and systematic analyses of bHLH proteins have been well conducted in Arabidopsis (AtbHLH), rice (OsbHLH) and tomato (SlbHLH) species. However, there are no reports of bHLH family genes have been functionally characterized in Persian walnut (Juglans regia). We identified a total of 189 bHLH genes in J. regia, which are clustering into 18 subfamilies. All JrbHLH contained the conserved domains HLH. A total of 69 JrbHLH genes were expanded as whole genome duplications (WGD). The syntenic analysis was conducted for Persian walnut (J. regia) with other two woody plants (P. trichocarpa and O. europaea) to infer the bHLH genes’ evolutionary relationship between these species . We identified a total of 42 pairs of orthologous bHLH genes between J. regia and P. trichocarpa, while only 29 orthologous gene pairs between J. regia and O. europaea, while 25 collinear gene pairs were found in three species J. regia, O. europaea and P. trichocarpa. Furthermore, JrbHLHs had different expressed patterns between reproduction and vegetative tissues based on the transcriptome expression profiles of female flowers, male flowers, leaves, and hulls, respectively. Specifically, both transcriptome data and quantitative polymerase chain reaction (qRTPCR) assessment showed that two JrbHLH genes (JrbHLH3-5 and JrbHLH13-13) were highly represented in female and male flowers, while one JrbHLH gene (JrbHLH13-4) was highly expressed in leaves. Genome-wide identification, gene structure, phylogeny and expression analysis of the JrbHLH # These authors contributed equally to this work. *e-mail: pengzhao@nwu.edu. cn DOI: 10.15244/pjoes/123113 ONLINE PUBLICATION DATE: 2020-11-26 Ullah I. , et al. 1832
An Analysis of Recirculatory Flow in Gas‐Stirred Ladles

The paper is concerned with the fluid mechanics characterizing the bulk flow region in a gas‐stirred ladle. A theoretical framework, previously derived for the analysis of the gas‐liquid plume region, is extended to include the bulk flow phenomena. In this study, the liquid recirculation and mixing have been quantified in terms of simple dimensionless parameters related to the ladle geometry and gas flow rate. A new correlation for mixing time, consistent with the proper form of the Froude similitude criterion, is presented. The work has implications for the fundamental as well as applied aspects of ladle processing.
Evidence of Nanostructure Development from the Molecular Dynamics of Poly(pentamethylene 2,5-furanoate)

We report on the molecular origin of poly(pentamethylene 2,5-furanoate) particular physical properties. From the structural point of view we found this polymer can develop crystallinity when stored at room conditions for months. On the other hand, we used broadband dielectric spectroscopy (BDS) measurements, to analyze in very detail the local and segmental molecular dynamics of the material subjected to several thermal treatments. In this way we evidenced that the molecular dynamics are sensitive to thermal history over a broad temperature range. This behavior has been attributed to possible inter-chain interactions detected via infrared spectroscopy and rheology measurements in the non-crystallized polymer.
Cytomorphometric Analysis of Buccal Exfoliated Cells in Patients With Iron Deficiency Anemia

Iron deficiency anemia can cause histopathologic alterations in the oral mucosa. Exfoliative cytology is a cheaper and less aggressive method for early diagnosis. The aim of this study was to compare the cytological and cytomorphometric characteristics of buccal exfoliated cells of iron deficiency anemic patients with those of healthy controls. This case-control study compared a group of 40 patients with iron deficiency anemia (IDA) with an age- and gender-matched control group (C) of 40 healthy individuals. The buccal mucosal smears were stained using the Papanicolaou technique for cytological analyses. Cellular clumping, cytoplasmic diameter (CD), nuclear diameter (ND), cytoplasmic area (CA), nuclear area (NA), nucleus to cytoplasmic area ratio (NA/CA), cellular and nuclear pleomorphism, micronuclei (Mn), binucleation, bacterial colonies, and keratin flakes were evaluated using a light microscope and digital image analysis. Mean values for IDA and C groups were: bacterial colonies (1.88 and 0.65; P=0.002); CA (2209.88 and 1687.79 μm²; P=0.006); Mn (1.60 and 0.60; P=0.02). Significant increases in bacterial colonies, CA and Mn were seen for the IDA group. The number of cellular clumps, CD, ND, NA, NA/CA, cellular and nuclear pleomorphism, binucleation, and the number of keratin flakes didn’t show significant differences between studied groups (P>0.05). There wasn’t any significant difference with respect to overall atypia. This study revealed that IDA was able to induce significant changes in CA and Mn of the oral epithelial cells. Exfoliative cytology and cytomorphometry can be used as a tool to assess the mucosal changes in IDA patients.
Operation of process equipment with crack-like defects

Analysis of the ‘layer separation’ defect of the base metal depending on the depth of its occurrence on the further safe operation of process equipment is carried out. The calculation is performed by the finite element method using ANSYS software package. The obtained results enable one to conclude that the layer separation does not have a significant effect on the bearing capacity of the equipment, while it is local and not being distributed.
