Short-Term Price Reaction to Filing for Bankruptcy and Restructuring Proceedings—The Case of Poland

This study aims to check market reaction to filing for bankruptcy and restructuring proceedings and to verify the short-term effect of a price reversal in the Polish market in the years 2004–2019. The research was conducted by dividing the analysed companies according to the procedure (bankruptcy and restructuring) and market (the main market and the NewConnect market). The research methodology used in the study is the event analysis method (AR, CAR, AAR and CAAR rates were used in the research), with a few statistical tests (T-test, Generalized rank Z Test, Generalized rank T-Test, Patell or Standardized Residual Test, Kolari and Pynnönen adjusted Patell or Standardized Residual Test). It was found that share prices in the Polish share market react quickly to public information about filing an application for bankruptcy or restructuring. For all analysed companies, the mean rate of return on the event day was equal to −14%, and on the next day, it was −3%. Regardless of the type of share market and the form of proceedings, the reversal effect was not confirmed in the short term. It was found that cumulative above-average rates of return fall more strongly for companies listed on the less liquid Newconnect market (−23.6%), and when information on the filing for bankruptcy proceedings is provided (−28.5%), as opposed to the main market (−19.1%) and restructuring proceedings (−17%). The cumulative average rate of return for all analysed companies in the research period (−2, +10 days) was equal to −20.6%.
Lessons for Euro markets from the first wave of COVID-19

Although the coronavirus pandemic hit Europe in the early days of 2020, European stock markets had signaled fluctuations in the days before. This paper assesses the observed volatility on European stock exchanges and searches for its sources during the first four months of 2020. To investigate the issue, a panel VAR model is adopted, and the generalized impulse response function and the variance decomposition methods are used. The estimations show that about 34% of the volatility in European stock markets is due to the Chinese stock market, while 7% is due to international uncertainty, as measured by VIX. The impact of pandemic cases and deaths on European stock markets is negligible, below 1%. This means that the European stock market faced two risk elements: the first is the transmission volatility from the Chinese stock market, and the second is the international uncertainty. The findings also support the view that COVID-19 is more like a systematic risk.
Social Comparison as Mediator: Does Instagram Intensity Predict Self-Esteem?

Instagram is one of the social media platforms that allow people to compare themselves with others (social comparison). Seeing the popularity of SNS, this study explores the role of social comparison as a mediator of the influence of Instagram usage intensity on users' self-esteem. The study was conducted using a mediation test technique through the PROCESS program, with 158 participants (25.95% male and 74.05% female) in the age range 18-25 years (M = 21.53, SD = 1.21). The measurement tools used were the Rosenberg Self-Esteem Scale (RSES), questions relating to social comparison behavior on Instagram, and the average duration spent using Instagram. The findings show that downward social comparison did not act as a mediator in predicting the influence of Instagram usage on young adults' self-esteem. On the contrary, our findings suggested upward social comparison mediates the relationship between Instagram usage and self-esteem. The implication of this study will be further discussed.
Exploring the relationships between motor proficiency, independence and quality of life in adolescents with autism spectrum disorder

The aim of this study was to explore the relationships between autism severity, motor performance, independence in daily living skills and quality of life in adolescents with autism spectrum disorder (ASD). The study included 31 participants, aged 13–18 years. Evaluations were made with the Gilliam Autistic Disorders Rating Scale-2 (GARS-2), Bruininks-Oseretsky Test of Motor Proficiency-2 Short Form (BOT-2-SF), Functional Independence Measure (WeeFIM II), and Pediatric Quality of Life Inventory (PedsQL). Motor performance of the participants was determined as below average according to the norms of BOT-2 SF, and were negatively correlated with GARS-2 at a moderate level (r = −0.61, p < 0.001), and a moderate negative correlation was determined between GARS-2 and WeeFIM II (r = −0.65, p < 0.001) and PedsQL (r = −0.61, p < 0.001). Independence in daily living skills (DLS) and autism severity were found to be significant predictors of PedsQL (R2 = 0.463, p < 0.05). Motor impairment still appears to be a missing piece of the puzzle for this age group. Promoting motor skill acquisition and independence could be a key factor in preventing the deterioration of physical health and improving quality of life in adolescents with ASD.
Assessment reform in Indonesia: contextual barriers and opportunities for implementation

ABSTRACT This paper seeks to understand the contextual influences that were considered important for shaping teachers’ use of Assessment for Learning (AfL). Using the micro, meso and macro-level contextual framework, the content analysis of teachers’ propositions drawn from semi-structured interviews and three group discussions unveiled both internal and external-to-school factors. Internally, the factors were associated with the students, teachers, resources at school and admission issues. A lack of ongoing involvement and support from the government and parents was mentioned as an external determinant. Besides considering these influences as barriers to innovation, teachers reported some potential opportunities that enabled them to perform assessment innovation, but evidence for the barriers outweighed the opportunities, which led to the perception that the reform was difficult to carry out. This implies that teachers’ approach to the AfL initiatives would rely heavily on the shallow approach of implementation. The study recommends that the incremental approach to reform implementation and sustainable professional development would need to be promoted to address the implementation barriers.
Willingness to Accept a COVID-19 Vaccine in Nigeria: A Population-based Cross-sectional Study

Background: The study assessed the intention to accept a future COVID-19 vaccine in Nigeria and associated factors. Materials and Methods: Between July 2020 and August 2020, a cross-sectional study was conducted using an online questionnaire that captured demographic data, risk perception, trust in government and public health authorities and willingness to accept a future COVID-19 vaccine. Data were analyzed using Statistical Package for Social Science version 21.0, Chi-square and logistic regression were carried out at a 95% confidence interval. Appropriate institutional ethical board approval and informed consent were obtained from all participants. Results: 1,228 responses were received over the study period. The mean age of respondents was 32.8 years (SD 10.4), 12.7% (156/1,228) were health workers, 66.9% (820/1,228) had tertiary level of education. Intention to accept a future COVID-19 vaccine was expressed by 50.2% (617/1,228) of respondents. Increasing age, male gender, trust in government, trust in public health authorities, confidence in vaccine developers, willingness to pay for and travel for a vaccine, and vaccination during an outbreak were significantly associated with COVID-19 vaccine acceptance. Healthcare workers and respondents with pre-existing medical conditions were not significantly different from non-healthcare workers and persons without medical conditions respectively with regards to the willingness to be vaccinated. Conclusion: One in two persons would accept a COVID-19 vaccine when it becomes available in the country. The government should take pro-active steps to address the factors that may potentially impact on the benefits expected from the introduction of COVID-19 vaccine and scale-up vaccine sensitization to improve potential acceptance for uptake across the country.
Cardiac Contractility Modulation in Patients with Heart Failure with Reduced Left Ventricular Ejection Fraction

Cardiac contractility modulation is an innovative therapy conceived for the treatment of heart failure. It is a device-based therapy, employing multiple electrodes to deliver relatively high-voltage (~7.5 V) biphasic signals to the endocardium of the right ventricular septum, in order to improve heart failure symptoms, exercise capacity and quality of life. Multiple clinical and mechanistic studies have been conducted to investigate the potential usefulness of this technology and, as of now, they suggest that it could have a place in therapy and meet a relevant medical need for a specific sub-category of underserved heart failure patients with reduced left ventricular ejection fraction. More studies are needed to further investigate its effect on outcomes such as mortality and rate of hospitalizations.
Polarity adverbs facilitate predictive processing in L2 Japanese

This study examines whether second language (L2) learners predict upcoming language prior to the verb in Japanese. Taking the dependency involving negative polarity adverbs – zenzen ‘at all’ and amari ‘(not) very’ – as a test case, this study examined whether Japanese native speakers and L2 learners of Japanese, aided by these adverbs, generate predictions of the polarity of the sentence-final verb. The visual-world paradigm experiment revealed that both native-speaker and L2-learner groups looked progressively more at the target picture before the negated verb when the information from adverbs was available than when it was not. The pattern of results underscores the usefulness of adverbial polarity items as predictive cues and indicates that they expedite the processing of negation in Japanese. Learners successfully exploited this information to generate nativelike predictions on sentence meaning.
Learning Experiences of a Participatory Approach to Educating for Sustainable Development in a South African Higher Education Institution Yielding Social Learning Indicators

A principle of sustainable development is that environmental matters are best handled with the participation of all concerned citizens. The UN has identified a gap between innovative teaching and learning methods and a participatory approach at institutions of higher education (IHE) to support interdisciplinary action. This paper shares the learning experiences of pre-service teacher students who took part in a participatory approach to educating for sustainable development in a South African IHE. A survey research design was used to collect the data from a large group (n = 376) of students over one semester. A qualitative research approach used the compulsory module’s teaching and learning tasks as intervention. Narratives were completed in groups upon completion of the module. This research established that when including a participatory approach in teaching and learning in an education for sustainable development (ESD) module at a South African IHE social learning indicators (learning, critical thinking, problem solving and dealing with conflict) emerged and students used their different perspectives when reasoning to participate collaboratively to work toward resolving environmental issues. The significance of this paper is that social learning indicators have been identified in multidisciplinary pre-service teaching and learning in a developing country when using a participatory approach in a higher education ESD module.
Diagnostic and prognostic value of 99mTc-Tektrotyd scintigraphy and 18F-FDG PET/CT in a single-center cohort of neuroendocrine tumors

Introduction The aim was to assess the diagnostic value of 99mTc-Tektrotyd scintigraphy (TCT) and positron emission tomography/computed tomography using F-18 fluorodeoxyglucose (18F-FDG PET/CT) in the detection and follow-up of neuroendocrine tumors (NETs), and their predictive value for disease progression. Material and methods In this retrospective cohort, TCT and 18F-FDG PET/CT were performed in 90 patients (37 men, 53 women, mean age 52.7 ±15.1), with NET. Correlation of Ki67 and tumor grade versus Krenning score and SUVmax was assessed, Kaplan-Meier analysis was used for progression-free survival (PFS), and Cox regression analysis was performed to identify the association between progression-related factors and PFS. Results Out of 90, true positive TCT was detected in 56 (62.2%) patients, true negative in 19 (21.1%), false positive in 4 (4.4%), false negative in 11 (12.2%), while 18F-FDG PET/CT was true positive in 69 (76.7%) patients, true negative in 10 (11.1%), false positive in 5 (5.5%), false negative in 6 (6.7%). Mean 18F-FDG PET/CT SUVmax was 6.8 ±6.2. Diagnostic sensitivity of TCT was 83.6%, specificity 82.6%, accuracy 83.3% vs. 18F-FDG PET/CT sensitivity was 92.0%, specificity 66.7%, accuracy 87.8%. A significant correlation between Ki67 and SUVmax was found in positive 18F-FDG PET/CT findings, unlike the correlation between Ki67 and Krenning score. Median PFS was 25 months (95% CI: 18.2–31.8), in 18F-FDG PET/CT positive patients 23 months (95% CI: 16.3–29.7) and 18F-FDG PET/CT negative 26 months (p = 0.279). Progression-free survival predictors were SUVmax and Krenning score. Conclusions In our study, TCT and 18F-FDG PET/CT have high diagnostic accuracy in detection of NET. Higher Krenning score on TCT and SUVmax in positive 18F-FDG PET/CT findings are predictors of disease progression. 99mTc-Tektrotyd scintigraphy and 18F-FDG PET/CT can be useful complementary tools in management of patients with NETs and in predicting patients’ outcome.
The Productivity and Nutrient Use Efficiency of Rice–Rice–Black Gram Cropping Sequence Are Influenced by Location Specific Nutrient Management

Nutrient management is critical for rice farming because the crop is grown under diverse conditions, and in most cases, the existing nutrient management practices fail to achieve an attainable yield target. During recent years site specific nutrient management gained importance for a target yield with maximum nutrient use efficiency. Sufficient research work has not been carried out in this direction so far in the rice–rice–pulse (black gram) sequential cropping system under the red and lateritic belt of West Bengal, India. A multi-locational field experiment was conducted from July 2013 to June 2015 at three different locations, namely, Guskara (Burdwan district) and Benuriya (Birbhum district) villages in farmers’ fields and at the university farm of Visva-Bharati, Sriniketan, West Bengal, India. The performance of nutrients was tested by providing ample doses of N, P, K, S, and Zn compared to the omission of these nutrients. The growth parameters, such as crop biomass production, leaf area index, and number of tillers, and yield attributes and yield were influenced by nutrient management treatments. Application of 100% of N, P, K, S, and Zn resulted in its superiority to other nutrient management options studied, and a similar trend was also noted with the treatment in the expression of nutrient use efficiency (NUE) and nutrient response (NR). The available N, P, K, S, and Zn contents in soil increased steadily due to the increase in fertilizer application. The study concluded that optimization of NPK in the rice–rice–pulse cropping system on target yield along with need-based S and Zn application was beneficial for higher productivity.
Corrosion Inhibition and Adsorption Behaviour of Methanol Extract of Spondiascytherea leaves on Mild Steel Corrosion in 5.0M H2SO4

The corrosion inhibition of mild steel in 5.0M sulphuric acid solutions by crude extracts of Spondias cytherea leaves (S.C) were studied using gravimetric and gasometric techniques. The results showed that S.C. can serve as a corrosion inhibitor in acid medium. Inhibition efficiencies (%I) of the S.C extract were found to reach 67.72 % and 72.00% for gravimetric and gasometric analyses respectively. The corrosion inhibition efficiency increased with increase in the concentration of the extracts and decreased with the increase in time and temperature. The corrosion inhibition efficiency exhibited by the S.C leaves extract is attributed to the stronger adsorption of the phytochemicals present in the plant extracts unto the mild steel. The mechanism of adsorption proposed for the S.C extract is physical adsorption. The corrosion inhibition of the leaves’ extracts followed Langmuir and Freundlich isotherm.
Liquid-Liquid Extraction and Selective Sorption of Actinides by Use of Carbamoyl-Phosphonic Ligands

A series of Carbamoyl-phosphonates and Carbamoyl-methylenephosphonates has been used for the liquid-liquid and selective sorption of a series of actinides. Liquid-liquid extraction into xylene layers has been investigated as a function of various experimental conditions and under the effect of different parameters. The extraction mechanism involves the formation of a 1 : 3 metal to ligand adduct, and the anion of the acid present in the aqueous samples plays a role in the phase transfer. The loading of a solid sorbent (XAD-4) with the ligand has been used for the selective sorption of actinides. The mechanism is similar to that operating in the liquid-liquid extraction. The uptake of the metals from the solution by the loaded resin may be used for recovery and preconcentration. hydrolysis of actinides may be repressed. As an example, bis-2-ethylhexylorthophosphoric acid (HDEHP) allows the extraction of elements in different oxidation states from HCl or HN03 solutions with yields following the sequence M(IV) > M(VI) > M(III) [12], while the extraction of actinide complexes with alkylamines follows an efficiency order which parallels their tendency to form anionic complexes [13]. For these products a strong effect of the dielectric constant of the medium is observed. Finally specific solvation of neutral complexes has also been applied for the extraction of metal species, and to this purpose compounds such as tris-w-butylphosphate (TBP) [14] or tris-n-octylphosphine oxide (ΤΟΡΟ) [15] have been used.
An analysis of the spatial and temporal distribution of large‐scale data production events in OpenStreetMap

Organized mapping activities within OpenStreetMap frequently lead to the production of massive amounts of data over a short period. In this article we utilize a novel procedure to identify such large‐scale data production events in the history of OpenStreetMap and analyze their patterns. We find that events account for a significant share of OpenStreetMap data and that organizational practices have shifted over time towards local knowledge‐based events and well‐organized data imports. However, regions in the “Global South” remain dependent on remote mapping events, pointing to uneven geographies of representation. We also find that events are frequently followed by periods of increased activity, with the exact nature of effects depending on contextual elements such as previous events. These findings portray organized activities as a significant and unique component which requires consideration when using OpenStreetMap data and analyzing their quality.
Year‐Round and Long‐Term Phytoplankton Dynamics in Lake Bonney, a Permanently Ice‐Covered Antarctic Lake

Lake Bonney (McMurdo Dry Valleys, east Antarctica) represents a year‐round refugium for life adapted to permanent extreme conditions. Despite intensive research since the 1960s, due to the logistical constraints posed by 4‐months of 24‐h darkness, knowledge of how the resident photosynthetic microorganisms respond to the polar winter is limited. In addition, the lake level has risen by more than 3 m since 2004: impacts of rapid lake level rise on phytoplankton community structure is also poorly understood. From 2004 to 2015 an in situ submersible spectrofluorometer (bbe FluoroProbe) was deployed in Lake Bonney during the austral summer to quantify the vertical structure of four functional algal groups (green algae, mixed algae, and cryptophytes, cyanobacteria). During the 2013–2014 field season the Fluoroprobe was mounted on autonomous cable‐crawling profilers deployed in both the east and west lobes of Lake Bonney, obtaining the first daily phytoplankton profiles through the polar night. Our findings showed that phytoplankton communities were differentially impacted by physical and chemical factors over long‐term versus seasonal time scales. Following a summer of rapid lake level rise (2010–2011), an increase in depth integrated chlorophyll a (chl‐a) occurred in Lake Bonney caused by stimulation of photoautotrophic green algae. Conversely, peaks in chl‐a during the polar night were associated with an increase in mixotrophic haptophytes and cryptophytes. Collectively our data reveal that phytoplankton groups possessing variable trophic abilities are differentially competitive during seasonal and long‐term time scales owing to periods of higher nutrients (photoautotrophs) versus light/energy limitation (mixotrophs).
Hydrostaticity in high pressure experiments: some general observations and guidelines for high pressure experimenters

ABSTRACT The characteristics of hydrostatic stress conditions are discussed and compared with real experimental observations made under high pressure with a diamond-anvil cell. While fluid pressure-transmitting media give a well-defined single stress condition, solid pressure-transmitting media give a variety of stress conditions within the limit of their shear strength under high pressure. Owing to its low shear strength, solid helium would be the best choice for a pressure-transmitting medium to at least 100 GPa. However, helium is so compressible that care should be taken on minimizing irregular deformation of a gasket hole, which often causes complicated stress states. A review is given on the quasi-hydrostatic limits of solidified pressure-transmitting media, and some ways to reduce nonhydrostaticity are discussed including the case of low-temperature experiments.
Effect of the Brain Balance Program® on Cognitive Performance in Children and Adolescents with Developmental and Attentional Issues

We reviewed the cognitive task performance of children and adolescents with developmental and attentional issues, before and after participation in the Brain Balance® (BB) program. The program consisted of three 1-hour sessions/week (sensorimotor stimulation and academic activities) with other multimodal activities, for 3 months. Participants were compared to a control group that had the same underlying demographic and phenotypical features but did not yet complete the program (participated on average for 27 days). For all ages (4-6 and 7+ years), we found a significant main effect of group, such that BB groups improved overall more than controls (CTRLs). More specifically, BB groups improved on all cognitive tests (three tests for ages 4-6 years; 12 tests for ages 7+ years), whereas CTRLs only improved on one test. These data support the potential of multimodal training programs toward the overarching goal of improving cognitive performance in children with developmental and attentional difficulties.
