Sentiment and Stock Returns: A Case for Conventional and Islamic equities in Pakistan

The study constructs market sentiment index over the period from August 2009 to June 2019 and examines the causality between market sentiment and returns for conventional and Islamic stocks in Pakistan. Using the firm-level data for all stocks listed on Pakistan Stock Exchange, market sentiment index is constructed as the first principal component of six variables: advances-to-decline, premium on dividends, price-to-earnings, relative strength, money flow and turnover rate. We employ the Vector auto-regression model to examine the two-way causal relationship between investor sentiment and aggregate stock return. Our results show that market sentiment has strong predictive power for subsequent conventional stock returns. Sentiment based trading actions of the investors cause persistence in conventional stock returns for one month; however, as these stocks become overpriced, the price movement reverses in two months’ time. In contrast, we do not find any significant association between market sentiment and Islamic stock returns. Our findings are suggestive of different dynamics and investor behavior in Islamic financial markets of Pakistan and along with the existing literature documenting Islamic stocks performance to be at least as good as the conventional stock can be a comfort to the Muslim Investors and may serve as the catalyst to stimulate the growth of Islamic equities.

Nanoporous Copper Films by Additive-Controlled Electrodeposition: CO2 Reduction Catalysis

Electrodeposition from plating baths containing 3,5-diamino-1,2,4-triazole (DAT) as an inhibitor gives Cu films exhibiting high surface area and high CO2 reduction activities. By changes in the pH and deposition current density, the morphologies of the Cu films are varied to exhibit wire, dot, and amorphous structures. Among these Cu films, the CuDAT-wire samples exhibit the best CO2 reduction activities activity with a Faradaic efficiency (FE) for C2H4 product formation reaching 40% at −0.5 V vs RHE, a FE for C2H5OH formation reaching 20% at −0.5 V vs RHE, and a mass activity for CO2 reduction at −0.7 V vs RHE of ∼700 A/g.
I.“Tortugas 2000-A Post Mortem: Evaluation of Actual versus projected socioeconomic impacts of the Dry Tortugas Ecological Reserve”

II. Abstract The final report summarizes primary and secondary data collected to evaluate the trends in commercial fishing following institution of the Dry Tortugas Ecological Reserve. The analysis of survey data indicates that the original projections of economic impact and fishery behavior were generally accurate in terms of relative changes in catch, effort and overall economic activity. The use of commercial fishing panels subsequent to the Tortugas 2000 process was shown to provide a representative index of change in overall fishery activity in the study area.
Vacuum UV photo-oxidation of poly(ethylene terephthalate)

Abstract Poly(ethylene terephthalate) (PET) was treated with vacuum UV (VUV) (λ = 104.8 and 106.7 nm) photo-oxidation using a microwave (MW) plasma of Ar as the radiation source and the results were compared to treatment with O atoms produced from a remote MW plasma of a gaseous mixture of Ar-O2 in the absence of radiation. X-ray photo-electron spectroscopy (XPS) detected a lower saturation level for the atomic % of O with VUV photo-oxidation (32 at%) than with O atom treatment (34 at% O). The C 1s curve fitting results for both treatment methods show a decrease in aromatic sp2 carbons and an increase in the amount of carbon-oxygen bonding due to the formation of the carbonyl (C=O) and carbonate-like (O-(C=O)-O) moieties for VUV photo-oxidation; and C-O-C, C=O, and O-C=O moieties for O atom treatment, respectively. Advancing water contact angle measurements showed more of an increase in hydrophilicity with the O atom treated samples than VUV photo-oxidation. Atomic Force Microscopy images displayed smoother surfaces after VUV photo-oxidation while O atom treatment resulted in insignificant changes in surface roughness. Rinsing the treated surfaces with ethanol solvent partially decreased the at% O indicating the formation of a weak boundary during treatment.
New patterns in the position of CEE countries in global value chains: functional specialisation approach

Research background: High servitisation of manufacturing makes it impossible to separate services from manufactured goods properly, which implies difficulties in the assessment of the position of the country on the smile curve, i.e. in the proper assignment of products or services to one of the industrial process steps: pre-production, pure fabrication or post-production services. Therefore, we propose to use the business functions of industries identified with the aid of labour market data rather than the industrial classification of products in order to create a more appropriate measure of the position of countries in GVCs. Purpose of the article: We aim to identify and analyse the patterns of functional specialisation for eight Central and Eastern European Countries (CEECs) — the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia and Slovenia — both at the country and industry level. In addition, we analyse functional specialisation patterns for Germany, which serves as a reference country. Methods: To assess functional specialisation patterns, we employ the methodology proposed by Timmer et al. (2019a). It allows us to obtain functional specialisation indices for four different business functions — management, R&D, marketing, and fabrication. To compute them, we Oeconomia Copernicana, 12(1), 35–52 36 combine two sources of data — domestic value added from decomposed sectoral input-output tables (the World Input Output Database) and the Occupations Database built up by Timmer et al. (2019a). Findings & value added: Our research shows a very heterogeneous pattern in CEEC countries' position in GVCs by taking into account their functional specialisation at the countries and industries levels. Poland and Slovakia focus primarily on low value-added fabrication processes, the Baltic countries and Slovenia specialise in management services, Hungary and Latvia gain in marketing services, and the Czech Republic and Slovenia win in R&D activities. We indicate that some CEE countries (Poland, Slovakia) could be stuck in a functional trap, and our approach could be a valuable tool for assessing the process of coming out of it.
Applying Positive Discipline in School and Adolescents’ Self-esteem

Starting from the general principles of the concept of positive discipline, the paper points out that schools and teachers can significantly contribute to the application of positive discipline to affect different aspects of a student’s personality development. The potentials of applying positive discipline in the school for developing adolescents’ self-esteem are particularly emphasized. Accordingly, this paper will present the results of a study that aimed to establish a correlation between assessing the presence of positive discipline in a school context and the level of adolescents’ self-esteem. The survey included a convenience sample of 195 high school students from three high schools - art, technical, and grammar school. The Rosenberg Self-Esteem Scale and the scale for assessing the presence of positive discipline in the school were used to collect the data. The results showed that adolescents exhibit a high level of self-esteem, while their assessment of the presence of positive discipline in school is moderate. Also, it was found that with the increase in the assessment of the presence of positive discipline in school, the level of adolescents’ self-esteem increased, and the statistically significant moderating role of the measured variables was found only in the type of high school. The conclusion points to the need to sensitize teachers to manage the classroom according to the principles of positive discipline, as well as the importance of creating the conditions that, through the phenomenon of positive discipline, effectively raise the quality of schoolwork as a whole.

THE ASYMMETRIC VOLATILITY OF THE ISLAMIC CAPITAL MARKET DURING THE COVID-19 PANDEMIC

This study attempts to identify the existence of asymmetric volatility in the Islamic capital market in Indonesia during the Covid-19 pandemic. The paper employs the symmetric analysis of the GARCH (1,1) model and the asymmetric analysis of the TGARCH (1,1) model in order to identify Islamic capital market behaviour duringthe first 200 days after the first Covid-19 cases were confirmed. We used the daily closing prices of the Indonesia Sharia Stock Index (ISSI). The symmetric analysis of the GARCH (1,1) model revealed that the current value of return on the ISSI does not have a significant impact on its future value. On the other hand, the TGARCH (1,1) model showed that the asymmetric parameter coefficient was positive and statistically significant. Good news and bad news does not have the same level of impact on the volatility of returns on the ISSI. Furthermore, coefficients αi and γi in the variance equation indicate that good news has a higher volatility impact than bad news. The results indicate that investors should not to worry about the bad news effect of theCovid-19 pandemic, while the government should continue the mitigation of the spread of the coronavirus along with its economic recovery policy.
Emotional Emptiness and Child Neglect: The Impact of Chronic Feelings of Emptiness in Human Capabilities

The present contribution aims to provide an analysis of the under-studied emotional state of emptiness. In order to do this, we firstly provide a description of the spectrum of emotional states of emptiness, their associated cognitions, antecedents and effects. Secondly, we focus on the cases where this state is chronified. By doing so, we aim to show the connection of chronic states of emptiness with neglect during childhood. Finally, we assume the Capability Approach developed by Martha Nussbaum as a normative framework that enables us to evaluate prolonged states of emotional emptiness and their effects upon the development of basic capabilities and the self as a potential instance of injustice.
Shifting from autograph to Selfie: consumer self in the Facebook world

The recent revolution of information technology has diffused Facebook widely among consumers, and it has a considerable impact on consumer self and modern marketing communication. Purpose of this study is to investigate the acceptance and impact of dematerialized Facebook possessions on consumer extended self. The theoretical foundation of Technology Acceptance Model (TAM) and extended self were used to develop the hypotheses of the study. The current study is based on primary data collected through a self-administered questionnaire, among a sample of 327 Sri Lankan undergraduates. Partial Least Squares Structural Equation Modeling (PLSSEM) was used to estimate the path coefficients and test the hypotheses developed in the study. Findings reconfirmed the original TAM relationships, enabling the use of TAM in identifying the predictors for accepting dematerialized Facebook possessions. Moreover, findings revealed that dematerialized Facebook possession usage extended consumer self. Theoretical and practical implications of these study and directions for further research are discussed.
Does Student’s Cognitive Flexibility Decrease During Pandemic? A New Approach to Measure Cognitive Flexibility

The aim of this study is to examine the cognitive flexibility before and during the COVID-19 pandemic through a different performance measurement suitable for online application In the study, three different data collected in 2019 (T19), 2020 (T20) and 2021 (T21) were compared with both within- and between-subject designs One-hundred-and-twenty-three university students were included in the study for within-subjects, 239 for between-subject According to the findings of the study, the cognitive flexibility of the students who continue formal education in T19 is higher than the students who continue distance education in T20 according to both within-subject and between-subject design Besides, in both designs, fewer total words were produced in T19 than in T20 The sentences created by the students who continue their distance education in pandemic stay around less categories and contain more words According to the within-subject findings obtained at T20 and T21, the cognitive flexibility and total words produced at T20 were greater In other words, the scores of the students decreased over time during the pandemic period In T21, cognitive flexibility is not related to vulnerability, perceived risk, and fear of COVID-19 However, according to the regression results, vulnerability at T21 was predicted by the total word and total emotional word in T20 Accordingly, producing more total words in T20 reduced vulnerability in T21;however, using more emotional words in T20 increased vulnerability in T21 In addition, the number of siblings was negatively associated with vulnerability Lastly, cognitive flexibility test was found to be reliable
The role of IL-6 receptor inhibitor treatment in critical patient monitoring with COVID-19

Objectives: The COVID-19 disease can manifest itself with acute respiratory distress syndrome, renal failure, and septic shock in critically ill patients. There are opinions that there is a correlation between high IL-6 levels and disease severity. In our intensive care unit, we evaluated the changes in the laboratory data and radiological involvement severity of our patients who underwent tocilizumab treatment and examined the appropriate laboratory parameter in the treatment follow-up and its effect on survival. Methods: In the critical patient follow-up of COVID-19, 17 of the 23 patients treated with tocilizumab had a mortal course (Group 1) and the remaining 6 (Group 2) were. The C-reactive protein, lactate dehydrogenase, IL-6, D-dimer, procalcitonin, albumin, and ferritin values, which were routinely screened in our clinic on the day of tocilizumab treatment and the 5th day after, were recorded. Both the change between the two groups and the change between days 1 and 5 were analyzed.Results: A total of 23 patients (55.35 ± 13.31 years) were included in the study. The computed tomography severity score assessed at the intensive care unit admission was statistically significantly higher in Group 2. The procalcitonin and lactate dehydrogenase values measured on day 5 after tocilizumab were significantly lower in Group 2. On the 5th day after treatment, the levels of C-reactive protein, ferritin, chest X-rays, IL-6 and D-dimer statistically significantly changed compared to the first day of the treatment. In correlation with the decrease in PCT as of the 5th day after tocilizumab administration, an increasing tendency was observed in 28-day survival.Conclusion: This study demonstrated that tocilizumab treatment may positively contribute to the treatment by decreasing cytokine levels. PCT and LDH follow-up before and after treatment in critically ill patients who are receiving tocilizumab treatment can give an idea about survival.

Effect of Protein-Polyphenol Ratio on the Size of Haze Particles

Various concentrations of the haze-active (HA) protein gliadin and the HA polyphenol tannic acid were combined in pH 4.5 buffer. The resulting hazes were measured by light scattering, and their particle size distribution patterns were examined with a laser diffraction particle size analyzer. The shape of the haze intensity response generally followed that seen in previous experiments, but haze intensity was noticeably greater with two particular gliadin-tannic acid ratios (2:1 and 5:1, w/w) than with other combinations. The size of the particles varied with the protein-polyphenol ratio, as previously hypothesized. In general, larger particles were seen with intermediate ratios, while both higher and lower proportions resulted in smaller particles. The data expressed as volume percent were highly quantized—essentially, only three particle sizes were seen. The proportions of these varied as the amounts of protein and polyphenol changed. The contributions of particles of each size to the haze intensity in different samples were estimated. The results suggested that the particles that contributed the most haze were typically in a narrow band, with diameters in the range of 10–20 μm. Variations in particle size induced by normal brewing practices are expected to have an impact on fining and filtration performance.
Raindrop fall velocity in turbulent flow: an observational study

Abstract. Laboratory measurements of drop fall speeds by Gunn–Kinzer under still air conditions with pressure corrections of Beard are accepted as the “gold standard”. We present measured fall speeds of 2 and 3 mm raindrops falling in turbulent flow with 2D-video disdrometer (2DVD) and simultaneous measurements of wind velocity fluctuations using a 3D-sonic anemometer. The findings based on six rain events are, (i) the mean fall speed decreases (from the Gunn–Kinzer terminal velocity) with increasing turbulent intensity, and (ii) the standard deviation increases with increase in the rms of the air velocity fluctuations. These findings are compared with other observations reported in the literature.
Opalescence of an IgG1 Monoclonal Antibody Formulation is Mediated by Ionic Strength and Excipients

Opalescence is a phenomenon that has been observed in several commercially available monoclonal antibodies, both in liquid and reconstituted lyophilized formulations. In this article, we demonstrated that an increase in the ionic strength of a monoclonal antibody formulation (MAb1) led to opalescence and higher viscosity. When the ionic strength was reduced, no opalescence in the MAb1 formulation was observed. The removal of polysorbate-80 (PS-80) from the formulation resulted in an increase in opalescence in NaCl-containing formulations, whereas it had no effect on formulations lacking NaCI. Differential scanning calorimetry with MAb1 formulations containing increasing amounts of NaCI indicated that formulations with higher ionic strength present a lower apparent melting temperature. Opalescent MAb1 formulations placed on stability remained unchanged after four weeks at 4 °C, whereas at 45 °C, an increase in dimers was observed. Using multi-angle light scattering, the MAb11 formulation was found to have a negative second virial coefficient.
