The Cost of Equity Capital in Stock Portfolios Listed on the Warsaw Stock Exchange Using the Classic CAPM

Abstract This work is an attempt to estimate the cost of equity capital characteristic among portfolios of companies listed on the Warsaw Stock Exchange in the years 1995-2017. To this end, the classic CAPM is used to estimate the cost of risk. Model tests are based on 252 monthly returns. In order to assess the errors of cost of capital estimation, the bootstrap method is used. The estimated cost of capital refers to the project portfolio with real options on these projects. Stock returns are generated not only by the companies implementing projects but also through real options modifying these projects. The estimated cost of capital can be a valuable indicator for portfolio managers. Also, it can be an approximate indicator for making decisions on the implementation of new investment projects. The estimated cost of capital assumes the highest values for value portfolios. The estimated cost of capital assumes the small values for growth portfolios.
Diet and feeding ecology of Eriocheir sinensis on the Polish coast of the Baltic Sea and in the Tagus Estuary, Portugal

Abstract The feeding ecology of the Chinese mitten crab Eriocheir sinensis was studied by analyzing the stomach fullness and its content with regard to sex, size and brackish water habitats occurring on the coast of the Baltic Sea (Gulf of Gdańsk and Vistula Lagoon, Poland) and the Atlantic (Tagus Estuary, Portugal). The presented results show that neither the site, sex (except the Gulf of Gdańsk) nor the size of an individual had a significant (p > 0.05) effect on the stomach fullness of E. sinensis. However, the type of food consumed was significantly (p < 0.05) correlated with the inhabited locality. The stomachs of crabs contained the remains of animal and plant origin, as well as detritus. The remains of animals (Bivalvia, Amphipoda, Gastropoda and Polychaeta) were more frequently found in the crabs from the Gulf of Gdańsk, while the remains of plants (Tracheophyta, Chlorophyta) were most often found in the stomachs of crabs from the Vistula Lagoon and the Tagus Estuary. Detritus was found only in the Gulf of Gdańsk and the Vistula Lagoon. Research indicates that the feeding ecology of omnivore E. sinensis is habitat specific, which should be taken into account when assessing the risk associated with this invasive species.
Forest stand biomass of Picea spp.: an additive model that may be related to climate and civilisational changes

Abstract Since ancient times, climate change has largely determined the fate of human civilisation, which was related mainly to changes in the structure and habitats of forest cover. In the context of current climate change, one must know the capabilities of forests to stabilise the climate by increasing biomass and carbon-depositing abilities. For this purpose, the authors compiled a database of harvest biomass (t/ha) in 900 spruce (Picea spp.) sample plots in the Eurasian area and used the methodology of multivariate regression analysis. The first attempt at modelling changes in the biomass additive component composition has been completed, according to the Trans-Eurasian hydrothermal gradients. It is found that the biomass of all components increases with the increase in the mean January temperature, regardless of mean annual precipitation. In warm zonal belts with increasing precipitation, the biomass of most of the components increases. In the process of transitioning from a warm zone to a cold one, the dependence of all biomass components upon precipitation is levelled, and at a mean January temperature of ˗30°C it becomes a weak negative trend. With an increase in temperature of 1°C in different ecoregions characterised by different values of temperature and precipitation, there is a general pattern of decrease in all biomass components. With an increase in precipitation of 100 mm in different ecoregions characterised by different values of temperature and precipitation, most of the components of biomass increase in warm zonal belts, and decrease in cold ones. The development of such models for the main forest-forming species of Eurasia will make it possible to predict changes in the productivity of the forest cover of Eurasia due to climate change.
The Myth of Austerity. Empirical Evidence from the Eurozone Countries

Abstract The paper discusses the impact of austerity policy on economic performance in the eurozone countries after the global crisis that occurred in 2007-08. The undertaken fiscal consolidation efforts to cut government expenditure and increase government taxes which begun in 2010, aimed to return sustainability in public finance as the rapid growth in sovereign debt was observed in many economies, especially in the South Europe. The implemented austerity policy under the external pressure not only amplified recession but also caused the further deterioration of public finance characterized by large deficits and increasing public debt. Based on the literature and empirical findings, the issue of austerity policy and its potential consequences on growth is examined. The research aim is to explore both advantages and disadvantages of austerity, focusing on the macroeconomic conditions which accompanied it and the impact of such policy on economic growth in the eurozone countries. The hypothesis of the negative influence of austerity on economic performance is verified on the basis of recent economic literature and conducted empirical research. Both descriptive analysis and dynamic panel regression based on two-step Generalized Method of Moments was used. Data from 2010-17 for the eurozone countries served to prove the existence of a key negative relationship between austerity policy and economic growth in economies that experienced deep great recession. The conducted analysis confirmed that austerity initiated to reduce the public debt to GDP doesn’t contribute to macroeconomic stabilization, adversely affecting potential output. Contrary to widely held opinion, this allows us to claim that austerity is not a good remedy for economies suffering from recession.
Postmortem Fluid Concentrations of Heroin Biomarkers and Their Metabolites

Only limited data exist concerning the utility of complementary specimens in heroin‐related deaths. As such, this report employed a validated LC‐MS‐MS method to quantify 6‐monoacetylmorphine (6‐MAM), 6‐acetylcodeine (6‐AC), and their metabolites morphine and codeine in blood with (BN) and without preservative (B) and the additional unpreserved specimens of vitreous humor, urine, stomach contents, and bile from 20 postmortem cases in which heroin was the primary cause of death. The median concentration of 6‐MAM in BN was 0.011 mg/L, B was 0.008 mg/L, urine was 0.186 mg/L, vitreous humor was 0.022 mg/L, stomach contents was 0.147 mg/L, and bile was 0.012 mg/L. Only one case was found to be positive for 6‐AC in B (case 6, 0.002 mg/L), and the median concentration of 6‐AC was 0.002 mg/L in BN, 0.012 mg/L in urine, 0.003 mg/L in vitreous humor, 0.057 mg/L in stomach contents, and 0.004 mg/L in bile. These findings present new information on the distribution of these analytes in complementary matrices and support their inclusion for accurately determining the role of heroin in opioid‐related deaths.
Framing the incidence of psychotic disorders: the case for context

Our recent study estimating the incidence of first-episode psychosis using population-based health administrative data (Anderson et al ., 2018), and the subsequent response from Hogerzeil and van Hemert (2019), has opened the door for a productive discussion of the importance of contextualizing incidence estimates. In our original paper, we present findings which suggest that estimates derived from specialized psychiatric services may underestimate population-based estimates of psychotic disorders. The response from authors Hogerzeil and van Hemert make use of these findings, as well as their own prior work in this area, to propose a framework that more clearly delineates the relationship between study design elements and incidence estimates. The authors use a three-dimensional figure to describe these relationships, assigning each axis a domain of study design: accuracy of diagnosis, coverage of services and time frame of diagnosis. Changes to these design parameters will influence the volume of the cube, and correspondingly the size of the incidence estimate. We agree with Hogerzeil and van Hemert that this is a crucial consideration for measuring and interpreting incidence estimates, which has indeed been largely overlooked in the literature to date.

Till death do us part: Transactions between losing one's spouse and the Big Five personality traits.

OBJECTIVE Although losing one's spouse is one of the worst experiences that can occur in life, it has not been resolved yet how this experience relates to personality development. METHOD In the German Socio-Economic Panel study (SOEP), information on the death of a spouse was assessed yearly from 1985 to 2017 and personality was measured repeatedly in 2005, 2009, 2013, and 2017 with the BFI-S. We used multilevel analyses to simultaneously model whether personality differed between individuals who did or did not lose their spouse and whether personality changed prior to and after this experience. RESULTS Compared to controls without the event, individuals who lost their spouse at a later point of time were more conscientious (β = 0.21) and more extraverted (β = 0.17). They became gradually more extraverted in the three years prior to the event (β = 0.25), but were less extraverted thereafter (β=-0.27). Moreover, they gradually increased in emotional stability in the three years after this experience (β = 0.30). These changes were primarily driven by women and middle-aged individuals. Men whose spouse died were less open in the first year after the event (β=-0.47). CONCLUSIONS Losing one's spouse relates to changes in extraversion and emotional stability, especially in women and middle-aged adults.
ASQ: Active Learning with Interactive Web Presentations and Classroom Analytics

Today it is commonly accepted that the effectiveness of instructional technology, measured as improvement over the learning outcomes of students, is highly correlated with the learning environment, the applied pedagogies and the goals of the participants of the learning process. The often applied passive lecture model and the undirected use of modern technology such as student laptops and smartphones has been associated with increased levels of inattention and poor student performance. To address this, our work is focused on creating instructional technology for orchestrating traditional post-secondary brick-and-mortar classrooms of computer science education where active learning is the pedagogy of choice. We promote active learning during interactive lectures featuring retrieval practice with open practice question types of all answer depth formats(recognition, cued/free recall) directly integrated with slides. These turn student devices from a source of distraction to a learning affordance. Moreover, we take advantage of modern real-time Web technologies and machine learning techniques to allow timely and effortless gathering, assessment and classification of all student responses and activity during lectures thus tackling issues of scale with extrinsic classroom activities. This dissertation introduces ASQ, a Web application for increasing teacher awareness by (i) turning student’s devices from distraction tools to learning affordances; (ii) facilitating the application of active learning with the use of question types of various formats and depth; and (iii) utilizing real-time data analytics to facilitate the collection of students submissions, accelerate feedback cycles and infer student behaviors dynamics. With ASQ lecture slides are transformed into an interactive social playground for knowledge construction where students experiment with the presented material (individually or collaboratively), answer questions and continuously give feedback about the lecture quality. We reinforce the role of teachers as the driver of classroom activity by providing them with information to follow the progress of the learning process, spot learning gaps or misconceptions early and provide feedback when needed. We begin by focusing on the engineering aspects of such an application and discusses in depth
Comparison of Neonatal Intubation Practice and Outcomes between the Neonatal Intensive Care Unit and Delivery Room

Background: Characteristics of neonatal tracheal intubations (TI) may vary between the neonatal intensive care unit (NICU) and delivery room (DR). The impact of the setting on TI outcomes is not well characterized. Objective: The aim of this study was to define variation in neonatal TI practice between settings, and identify the association between setting and TI success and safety outcomes. Design: This was a retrospective cohort study of TIs in the National Emergency Airway Registry for Neonates from October 2014 to September 2017. The setting (NICU vs. DR) was the exposure of interest. The outcomes were first attempt success, course success, success within 4 attempts, adverse TI-associated events, severe desaturation, and bradycardia. We compared TI characteristics and outcomes between settings in univariable analysis. Factors significant in univariable analysis (p < 0.1) were included in a logistic regression model, with adjustment for clustering by center, to identify the independent impact of the setting on TI outcomes. Results: There were 3,145 TI encounters (2279 NICU, 866 DR) in 9 centers. Almost all baseline characteristics significantly varied between settings. First attempt success rates were 48% (NICU) and 46% (DR). In multivariable analysis, the setting was not associated with first attempt success. DR was associated with a higher adjusted OR (aOR) of success within 4 attempts (1.48, 95% CI 1.06–2.08) and a lower aOR for bradycardia (0.43, 95% CI 0.26–0.71). Conclusion: Significant differences in patient, provider, and practice characteristics exist between NICU and DR TIs. There is substantial room for improvement in first attempt success rates. These results suggest interventions to improve safety and success need to be targeted to the distinct setting.
Randomized Evaluation of the National Collegiate Athletic Association’s Concussion Education Fact Sheet for Coaches

Background. Concussion education for coaches is being increasingly recommended by leading sports organizations, yet the effectiveness of available materials has not often been assessed. This study evaluated the impact of the National Collegiate Athletic Association’s (2017) publication: “Concussion safety: What coaches need to know” (the “NCAA Fact Sheet for Coaches”) on participants’ concussion knowledge and safety supportive intentions. Method. NCAA head coaches (n = 779) were randomized to view the NCAA Fact Sheet for Coaches either before (intervention condition) or after (control condition) responding to questions assessing concussion knowledge and intentions to engage in three behaviors (talk to team about concussion safety; allow symptomatic athlete to continue play; encourage medical staff to return athlete as quickly as possible). Results. Knowledge scores were significantly higher among coaches in the intervention condition as compared to the control condition, largely driven by differences in knowledge about the consequences of continued play postconcussion (injury, reaction time, possible death). Fewer coaches in the intervention condition expected that they would allow an athlete with a suspected concussion continue to participate in a game or practice or that they would encourage medical staff to return athletes to play as quickly as possible. Discussion. The present study provides evidence that educational content, like that contained in the NCAA Fact Sheet for Coaches, may have a positive short-term impact on concussion knowledge and behavioral intentions of coaches. In light of these findings, sports organizations should consider providing similar educational materials to coaches, evaluating whether the information is impactful in their population.
Osteopathic Manipulative Treatment for Allostatic Load Lowering

Abstract Context Limited research has been done to examine osteopathic manipulative treatment (OMT) effects on modulating a compilation of allostatic load (AL) biomarkers that work to measure the body's multisystem response to homeostatic deviation. Objective To examine the efficacy of OMT on graduate students’ overall health through an objective index of representative AL biomarkers. Methods A within-subject pre- and postintervention study was conducted at Touro University College of Osteopathic Medicine in California during the fall 2017 semester. Graduate students enrolled in the Masters of Science in Medical Health Sciences program volunteered to participate in the study and received treatment by an osteopathic physician. The participants were evaluated using the following measures: Trier Inventory for the Assessment of Chronic Stress; diurnal urine cortisol and catecholamines; dried blood glycated hemoglobin, dehydroepiandrosterone, high-density lipoprotein, and high-sensitivity C-reactive protein; blood pressure, body mass index, and waist-to-hip ratio before (preintervention) and after (postintervention) OMT. Results The study consisted of 1 man (participant 1) and 1 woman (participant 2) aged 23 and 22 years, respectively. Participants were enrolled in the same academic program and received 3 OMT sessions in 7 weeks. Analysis of AL biomarkers revealed a decrease in overall AL scores from preintervention to postintervention in participant 1 (from 7 to 4) and participant 2 (from 9 to 7). Analysis of Trier Inventory for the Assessment of Chronic Stress scores revealed a decrease in self-perceived stress from preintervention to postintervention in participant 1 (from 18 to 15) and in participant 2 (from 40 to 13). Conclusion The OMT protocol used in the current study decreased measures of overall AL and self-perceived stress in both participants. This finding suggests that OMT may represent a reasonable modality to reduce AL and self-perceived stress in graduate students. Since the current study is limited by its small sample size, further research is warranted.
A Review of the Effects of Glucagon-Like Peptide-1 Receptor Agonists and Sodium-Glucose Cotransporter 2 Inhibitors on Lean Body Mass in Humans

Weight loss is an important goal in the management of several chronic conditions, including type 2 diabetes mellitus, and pharmacological therapies that aid weight loss are appealing. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter 2 inhibitors (SGLT2is) are novel glucose-lowering therapies that have been shown to induce clinically significant reductions in body weight. However, this weight loss may not be attributed solely to fat mass (FM). Given the importance of skeletal muscle and lean body mass (LBM) on cardio-metabolic health and physical function, we reviewed the available literature reporting the effects of GLP-1RAs and SGLT2is on body composition. Results demonstrate that, in most circumstances, the weight loss associated with both therapies predominantly comprises a reduction in FM, although significant heterogeneity exists between studies. In over half of the studies identified, the proportion of LBM reduction ranged between 20% and 50% of total weight lost, which is consistent with diet-induced weight loss and bariatric surgery. No clear differences existed between GLP-1RAs and SGLT2is. Consequently, the loss of LBM and skeletal muscle associated with weight loss induced by GLP-1RAs and SGLT2is warrants attention. Strategies to preserve skeletal muscle and improve physical function, for example through structured exercise, are of great importance.
VASCULAR-1 and VASCULAR-2 as a New Potential Angiogenesis and Endothelial Dysfunction Markers in Peripheral Arterial Disease

The quotient of concentrations concerning the key proangiogenic factor, that is, the vascular endothelial growth factor (VEGF-A) and the angiogenesis inhibitor, namely, its soluble receptors (sVEGFR-1 or sVEGFR-2), seems to reflect increased hypoxia and intensity of compensation angiogenesis. Therefore, it can be an ischemic and endothelial dysfunction marker reflected in intermittent claudication (IC) or critical limb ischemia (CLI) in patients with symptomatic peripheral arterial disease (PAD). The main objective of this study was to evaluate the levels of VEGF-A/sVEGFR-1 and VEGF-A/sVEGFR-2—presented using a novelty acronym VASCULAR-1 and VASCULAR-2—in patients with IC and CLI, as well as displayed in 4 classes of severity of PAD. VASCULAR-1 and VASCULAR-2 were calculated using the plasma of venous blood sampled from 80 patients with IC (n = 65) and CLI (n = 15) and the control group (n = 30). Patients with CLI were reported to have a slightly higher index of VASCULAR-1 and double VASCULAR-2 levels as compared to patients with IC (P = nonsignificant), and these markers were significantly higher than controls (P < .01 and P < .01, respectively). VASCULAR-2 levels were observed to have an increasing tendency in the subsequent degrees of PAD severity according to the Fontaine classification (P = .02). In view of the need to consider the role of the proangiogenic and antiangiogenic factor in the assessment of the so-called “angiogenic potential,” VASCULAR-1 ratio and VASCULAR-2 ratio may be a new useful biomarker of limb ischemia in patients with IC and CLI. However, this requires further studies and evidence on a very large group of patients with PAD.
Job satisfaction and associated factors among psychiatric nurses in tertiary psychiatric hospitals: Results from a nationwide cross-sectional study.

AIMS To investigate job satisfaction among psychiatric nurses in China and to explore its associated factors. DESIGN A cross-sectional survey among a nationwide sample from 32 tertiary psychiatric hospitals in 29 provincial capitals in China. METHODS Nurses (N = 9.907) were targeted for this survey in December 2017. 8,493 responded (response rate = 85.7%) and 7,881 (79.5%) were included in the analysis. An online questionnaire was used to collect demographics and factors related to the work environment. The short version of the Minnesota Satisfaction Questionnaire was used to assess job satisfaction. Multilevel regression was used to examine the association between job satisfaction and these factors. RESULTS The mean job satisfaction score was 73.7. The multiple regression analysis indicated that self-rated health, monthly income, medical liability insurance coverage, perceived respect from patients, social recognition, nurse-physician collaboration and trust were significantly associated with higher job satisfaction scores, while age, work hours and directly experiencing patient-initiated violence was negatively associated with job satisfaction (p < .05). CONCLUSION Overall, Chinese psychiatric nurses is closer to satisfied than neutral and some demographics and factors related to stressful work environments were associated with nurses' job satisfaction scores. IMPACT This study examined factors associated with the job satisfaction of Chinese psychiatric nurses in a nationwide sample and indicated that to improve nurses' job satisfaction, the government and hospital administrators could consider ways to promote nurses' personal health and to modify the stressful work environments, such as improving income, reducing work hours, promoting the psychiatric nursing specialty in ways that increase the public's respect for it, increasing awareness of medical liability insurance coverage and protecting nurses from patients' violence.
