Assessing the Effect of Dynamic Capabilities on the ESG Reporting and Corporate Performance Relationship With Topic Modeling: Evidence From Global Companies

The primary purpose of this study is to examine the relationship between the dynamic capabilities (DCs) embedded in ESG management, which are being pursued by global companies, and corporate performance amid increasing uncertainty. Furthermore, the secondary purpose is to examine the function of environmental uncertainty moderating the DCs-performance relationship. Concerning the analysis tool, this study employs topic modeling with Word2Vec embedding that analyzes unstructured data. This was employed as an alternative method beyond the limitations of the traditional approach, i.e., survey or interview. A DCs dictionary was constructed by redesigning the 12 detailed dimensions of Teece’s DCs into 10 dimensions, and then time series scores of individual global companies were extracted by applying this dictionary to the sustainability reports of 97 companies. Sustainability reports of 153 companies among Fortune Global 500 companies announced in 2020 were originally collected, but in the process of collecting additional financial data about these companies from OSIRIS, a total of only 97 companies was selected in the end due to omission of data. A fixed effect panel analysis was conducted, and the main findings are as follows: First, the DCs embedded in ESG management have a positive or negative direct effect on corporate performance. In particular, a statistically significant relationship was not observed in the innovation (technology) oriented capabilities, whereas a statistically significant positive relationship was observed in the customer (market) oriented capabilities. Second, uncertainty moderates the relationship between DCs and corporate performance positively or negatively. Interestingly, the moderating effect of uncertainty only appears in the function of the sensing and reconfiguring capabilities. From this, it can be seen that the function of DCs, which is embedded in the ESG management of global companies, is limited due to the imbalance between the sensing-seizing-reconfiguring capabilities. These findings imply that, despite the positive function of DCs embedded in ESG management, costs and benefits occur at the same time, and DCs can improve performance only if there is an organizational adaptation strategy suitable for uncertainty. Accordingly, business managers need to recognize the importance of pursuing sensing-seizing-reconfiguring capabilities in a balanced way to improve corporate performance through ESG management under uncertainty.
Arachidonic Acid in Follicular Fluid of PCOS Induces Oxidative Stress in a Human Ovarian Granulosa Tumor Cell Line (KGN) and Upregulates GDF15 Expression as a Response

Polycystic ovarian ovary syndrome (PCOS) is the main cause of ovulatory infertility and a common reproductive endocrine disease of women in reproductive age. In addition, nearly half of PCOS patients are associated with obesity, and their total free fatty acids tend to increase. Arachidonic acid (AA) is a polyunsaturated fatty acid. Oxidation products of AA reacting with various enzymes[cyclooxygenases (COX), lipoxygenases (LOX), cytochrome P450s (CYP)] can change cellular mitochondrial distribution and calcium ion concentration, and increase reactive oxygen species (ROS) production. In this study, we analyzed the follicular fluid fatty acids and found higher levels of C20:4n6 (AA) in PCOS patients than in normal control subjects. Also, to determine whether AA induces oxidative stress (OS) in the human ovarian granulosa tumor cell line (KGN) and affects its function, we treated KGN cells with or without reduced glutathione (GSH) and then stimulated them with AA. The results showed that AA significantly reduced the total antioxidant capacity (TAC) and activity of antioxidant enzymes and increased the malondialdehyde (MDA), ROS and superoxide anion(O2-)levels in KGN cells. In addition, AA was also found to impair the secretory and mitochondrial functions of KGN cells and induce their apoptosis. We further investigated the downstream genes affected by AA in KGN cells and its mechanism of action. We found that AA upregulated the expression of growth differentiation factor 15 (GDF15), which had a protective effect on inflammation and tissue damage. Therefore, we investigated whether AA-induced OS in KGN cells upregulates GDF15 expression as an OS response.Through silencing of GDF15 and supplementation with recombinant GDF15 (rGDF15), we found that GDF15, expressed as an OS response, protected KGN cells against AA-induced OS effects, such as impairment of secretory and mitochondrial functions and apoptosis. Therefore, this study suggested that AA might induce OS in KGN cells and upregulate the expression of GDF15 as a response to OS.
Altered Brain Topological Property Associated With Anxiety in Experimental Orthodontic Pain

Background Orthodontic pain is orofacial pain caused by tooth movement. Anxiety is a strong predictor of the severity of such pain, but little is known about the underlying neuropsychological mechanisms of such effects. The purpose of this study was to investigate the effect of orthodontic pain on brain functional networks and to define the mediating role of anxiety in orthodontic pain and brain function. Methods Graph theory-based network analyses were applied to brain functional magnetic resonance imaging data from 48 healthy participants exposed to 24 h orthodontic pain stimuli and 49 healthy controls without any stimulation. Results In the experimental orthodontic pain stimulation, brain functional networks retained a small-world organization. At the regional level, the nodal centrality of ipsilateral brain nodes to the pain stimulus was enhanced; in contrast the nodal centrality of contralateral brain areas was decreased, especially the right mid-cingulate cortex, which is involved in pain intensity coding. Furthermore, anxiety mediated the relationship between nodal efficiency of mid-cingulate cortex and pain severity. Conclusion The results illuminate the neural mechanisms of orthodontic pain by revealing unbalanced hemispherical brain function related to the unilateral pain stimulation, and reveal clinically exploitable evidence that anxiety mediates the relationship between nodal function of right mid-cingulate cortex and orthodontic pain.
An estimation and verification of vessel radar-cross-sections for HF surface wave radar

The radar cross sections (RCS) of both small and large ships for High Frequency Surface Wave Radar (HFSWR) were studied by using Numerical Electromagnetics Code and by using measurements from a HFSWR system at Cape Race, Newfoundland, Canada. The results of the study indicate that Teleost, a 2405-ton Canadian Coast Guard ship, and large cargo-container vessels (/spl sim/36000 ton) have comparable RCS values at 3.1 and 4.1 MHz. This was verified by comparing Teleost signals with the reflections of seven cargo-container vessels identified during an operational evaluation of the HFSWR. The conclusion of the study is that Teleost and the large cargo-container vessels have an angle-averaged RCS of /spl sim/40dBm/sup 2/, while small vessels (/spl sim/1000 tons) could reasonably be characterized by an angle-averaged RCS of /spl sim/30 dBm/sup 2/, in the lower end of the HF band (3-5 MHz).

The influence of agglomeration on growth: A study of Argentina

: This paper analyses the influence of agglomeration on economic growth in the Argentinian provinces for the period 1981–2007 using fixed effects and GMM estimation for panel data. The choice of the estimation approach is crucial. After controlling for potential simultaneity bias, there is evidence of a link between agglomeration and growth in the Argentinian provinces, suggesting that the Williamson hypothesis is in place.
STRATEGIES FOR DEVELOPING CREATIVITY, CRITICAL, COMMUNICATION AND COLLABORATION: A COMPARATIVE TEACHING USING EXPLICIT AND METACOGNITIVE STRATEGIES

The aim of this study was to identify the ability of students to use explicit and metacognitive strategies. A descriptive analysis was utilized on the instruments namely letter writing, comic strip and dramatization. Results showed that the ability of students using the explicit strategy of acquired ability in critical thinking and communication was Fairly Good (FG), and Good (G) acquired ability in creativity and collaboration. In the metacognitive strategy, the ability of students in critical thinking, creative thinking and communication skills was Fairly Good (FG), and Good (G) acquired collaborative ability. There was no significant difference between explicit and metacognitive strategies in developing the ability of students in Grades 6 to 4 C’s. The researcher suggested that there will be another study similar to this in which many students will participate. Article visualizations:
Chronic abdominal pain in children aged 5 - 15 years: An insight of psychosocial factors

--- Background: Mostly, chronic abdominal pain (CAP) is detected with no abnormality. Therefore, focuses on psychosocial issues of children with CAP may throw light on etiology of this disorder and inputs for management. Objective: To study the psychosocial factors related with CAP and association between them in children. Methodology: In a prospective, hospital-based case control study, 199 children (aged 5-15 years) were enrolled. Children were split into cases (n=50, with CAP) and controls (n-149, without CAP). Cases were further divided into organic and nonorganic groups based on their symptoms. Baseline investigations like urine and stool routine, ultrasound (abdomen and pelvis) was done for cases. Psychosocial assessment was done in all patients. Results: Around 88% children in cases group had nonorganic pain and 12% had organic pain. Most children with nonorganic pain were females (52%). A significant association noted between type of stool, USG abdomen results, and characteristic of pain with type of abdominal pain (organic and nonorganic) ( P <0.001). A significant difference noted between cases and controls in term of birth order, school
Can the Standard Configuration of a Cardiac Monitor Lead to Medical Errors under a Stress Induction?

The essential factor that enables medical patient monitoring is the vital signs monitor, whereas the key in communication with the monitor is the user interface. The way the data display on the monitors is standard, and it is often not changed; however, vital signs monitors are now configurable. Not all the data have to be displayed concurrently; not all data are necessary at a given moment. There arises a question: is the standard monitor configuration sufficient, or can it lead to mistakes related to delays in perceiving parameter changes? Some researchers argue that mistakes in life-saving activities is not mainly due to medical mistakes but due to poorly designed patient life monitor interfaces, among other reasons. In addition, it should be emphasized that the activity that saves the patient’s life is accompanied by stress, which is often caused by the chaos occurring in the hospital emergency department. This raises the following question: is the standard user interface, which they are used to, still effective under stress conditions? Therefore, our primary consideration is the measure of reaction speed of medical staff, which means the perception of the changes of vital signs on the patient’s monitor, for stress and stressless situations. The paper attempts to test the thesis of the importance of the medical interface and its relation to medical mistakes, extending it with knowledge about the difference in speed of making decisions by the medical staff with regard to the stress stimulus.

The Influence of Political Efficacy on Voter Turnout in South Africa

ABSTRACT South Africa's recent democratic elections have witnessed a decline in political participation. Yet few studies examine the influence of political efficacy on the decision to participate. Using 2014 and 2019 post-election public opinion survey data captured after these respective national and provincial elections, the paper addresses a research gap by demonstrating a relationship between a respondent's level of internal and external political efficacy and their likelihood of voting across two consecutive elections. It finds that external political efficacy, and to a lesser extent, internal efficacy shapes the decision to vote. The responsiveness of the political system is a key determinant of voting even after other key predictors of participation are accounted for. It concludes that years of state-based failures have eroded citizen perceptions of political system responsiveness which has, in turn, undermined how citizens perceive the utility of their vote.
Effect of Mitotane on Male Gonadal Function

Simple Summary Mitotane (MTT) is the treatment of choice for adrenocortical carcinoma. Male hypogonadism is often diagnosed in male patients treated with this drug. This research aims to consider possible side effects induced by MTT in the testis and a hypothetical detrimental effect deriving from androgenic deficiency. Furthermore, considering the increased potentiality of treatment for adrenocortical carcinoma, we want to provide male patients of childbearing age, as in other oncological diseases, the opportunity to consider a sperm cryopreservation program. Abstract Background: Clinical evidence has shown frequent hypogonadism following mitotane (MTT) treatment in male patients with adrenocortical carcinoma. This study aimed to evaluate the impact of MTT on male gonadal function. Methods: Morphological analysis of testes and testosterone assays were performed on adult CD1 MTT-treated and untreated mice. The expression of key genes involved in interstitial and tubular compartments was studied by real-time PCR. Moreover, quantitative and qualitative analysis of spermatozoa was performed. Results: Several degrees of damage to the testes and a significant testosterone reduction in MTT-treated mice were observed. A significant decline in 3βHsd1 and Insl3 mRNA expression in the interstitial compartment confirmed an impairment of androgen production. Fsh-R mRNA expression was unaffected by MTT, proving that Sertoli cells are not the drug’s primary target. Sperm concentrations were significantly lower in MTT-treated animals. Moreover, the drug caused a significant increase in the percentage of spermatozoa with abnormal chromatin structures. Conclusion: MTT negatively affects the male reproductive system, including changes in the morphology of testicular tissue and reductions in sperm concentration and quality.
Ecological Synthesis of CuO Nanoparticles Using Punica granatum L. Peel Extract for the Retention of Methyl Green

The aqueous extract from the bark of Punica granatum L. was invested to generate CuO nanoparticles from CuSO4 using a green, economical, ecological, and clean method. The synthesized nanoparticles were characterized and were successfully used as adsorbents for methyl green retention of an absorptive capacity amounting to 28.7 mg g−1. Methyl green equilibrium adsorption data were correlated to the Langmuir model following the pseudo-second order kinetics model. This study clearly corroborates that copper nanoparticles exhibit a high potential for use in wastewater treatment.
Academic Interest and Self-esteem as Correlates of Secondary School Students’ Academic Achievement in English Language in Nigeria

Aims: This study examined academic interest and self-esteem as correlates of secondary school students’ academic achievement in English language in Nigeria. Study Design: Correlational survey Place and Duration of Study: Anambra State, Nigeria, conducted between December 2021 and March 2022. Method: The accessible population for this study comprises 18,297 senior secondary school two SS2 students from 261 secondary schools situated in the six education zones in Anambra state, the sampling technique adopted was the proportionate stratified random sampling technique. This was use to select 2,160 SS 2 students. The instruments adopted for data collection are: students’ academic interest scale, self-esteem scale and students’ academic achievement scores in English language. Pearson Product Moment Correlation and Multiple Regression Analysis were statistical tools adopted for data analysis. Results: Table 1, 2 and 3 revealed a moderate positive relationship between secondary school students’ academic interest, self-esteem jointly with their academic achievement in English language. Similarly, hypothesis in Table 4, 5 and 6 reports that at 0.05 level of significance and 2158df, the t-test statistic value 15.95 with a Pvalue of 0.00 is less than 0.05, hence the second hypotheses is rejected. This implies that the relationship existing between self-esteem and academic achievement of secondary school students in English language in Anambra State is significant. Furthermore, at 0.05 level of significance 3df numerator and 2045df denominator, the F statistics value 314.12, with Pvalue of 0.00 is less than 0.05, the third null hypothesis is rejected. This goes to show that the relationship existing among secondary school students’ academic interest and self-esteem jointly with academic achievement in English language is significant. Conclusion: This study concludes that the joint relationship existing among academic interest, self-esteem jointly with the academic achievement of secondary school students in English language was reported to be moderate and also positive. This implies that the coefficient was close to 1.00 (perfect relationship). Justifying this, it could be likened to the fact that students only spend 45 to 90 minutes per day in school with each teacher, so it is nearly impossible for them to unconsciously transmit all of the knowledge they need to get to them within that time frame. So therefore, there is need for parents as well to fulfil their first job, which is to be a teacher to their children. In the same vein, the relationship existing among secondary school students’ academic interest and self-esteem jointly with academic achievement in English language is statistically significant.
Transformational Leadership on Performance: Mediating Role of Flexible Work Arrangements and Work Engagements (Study on the Coffee Shop Industry in Yogyakarta)

This study deals with the effect of transformational leadership and flexible work arrangement on performance through work engagement as an intervening variable in the cafe industry in Yogyakarta. The purpose of this study was to determine the effect of the variables to be studied, namely transformational leadership, flexible work arrangement, work en- gagement, and performance. Respondents in this study were 106 workers from 34 cafes in Yogyakarta. The data collection method in this study used a questionnaire with 5 Likert scales. The results of this study indicate that there is a positive effect of the variables tested for both direct and indirect impact. However, the value is not greater than the immediate effect. This research aims to increase the opportunities for determining flexible work arrangements, strengthening transformational leadership, especially em- ployee motivation and involvement, and maintaining performance through a suitable communication process.
Graphene-Based Temperature Sensors–Comparison of the Temperature and Humidity Dependences

Four different graphene-based temperature sensors were prepared, and their temperature and humidity dependences were tested. Sensor active layers prepared from reduced graphene oxide (rGO) and graphene nanoplatelets (Gnp) were deposited on the substrate from a dispersion by air brush spray coating. Another sensor layer was made by graphene growth from a plasma discharge (Gpl). The last graphene layer was prepared by chemical vapor deposition (Gcvd) and then transferred onto the substrate. The structures of rGO, Gnp, and Gpl were studied by scanning electron microscopy. The obtained results confirmed the different structures of these materials. Energy-dispersive X-ray diffraction was used to determine the elemental composition of the materials. Gcvd was characterized by X-ray photoelectron spectroscopy. Elemental analysis showed different oxygen contents in the structures of the materials. Sensors with a small flake structure, i.e., rGO and Gnp, showed the highest change in resistance as a function of temperature. The temperature coefficient of resistance was 5.16−3·K−1 for Gnp and 4.86−3·K−1 for rGO. These values exceed that for a standard platinum thermistor. The Gpl and Gcvd sensors showed the least dependence on relative humidity, which is attributable to the number of oxygen groups in their structures.
Optimizing Age of Information and Security of the Next-Generation Internet of Everything Systems

We analyze the information exchange and interactions among the major components, i.e., people, things, data, and processes, of the Internet of Everything (IoE) system, where raw data generated by people and things must be processed to obtain relevant higher level information that can be utilized by IoE processes for decision making and actions. Accordingly, the value of information obtained in the IoE system depends on the Age of Information (AoI)—time elapsed from the moment when raw data is generated to the moment when the data is processed and delivered to the processes. To reduce the AoI, the system is realized in the multiaccess edge computing network, where data can be processed by the edge devices (EDs) in proximity to people, things, and processes. The system security and resilience are further enhanced through coded distributed computing when each data input of EDs is encoded with a specific encoding function so that the final result of data processing by EDs can be recovered even if some processing outputs of EDs are erroneous or delayed. We then define a stochastic optimization problem where the AoI, security, and resilience are optimized jointly to maximize the expected long-term system payoff—difference between the value of information and data processing costs. Since this problem is hard to solve directly due to hidden information about the correctness of processing outputs returned by EDs, we develop a machine learning (ML) framework to obtain the problem solution.
