Do Chief Executive Officer’s Attributes Impact on the Performance of Nigerian Firms?
Authors: Augustine Chukwujekwu ODUBUASI , Johnson I. ANENE , Prince Chinedu OKEKE
Published: January 2023

This study investigated the effect of Chief Executive Officer’s (CEO) attributes on the performance of manufacturing firms listed on the Nigeria Stock Exchange (NSE). In line with the ideals of upper echelon theory that firms are reflective of the cognitive behaviours of the CEO, we examined such attributes as CEO education, experience and gender on the performance and value of manufacturing firms. Secondary data were collected from the firms’ annual reports from 2013 to 2021, which was made suitable by the adoption of ex post facto research design. Thirty-six firms were purposely selected for the study wherein the data were analysed with the descriptive statistics, correlation and panel regression analysis. The results of the study indicate that CEO characteristics jointly have a significant effect on firm performance and firm value which were measured by Return on Equity (ROEQ) and Tobin’s Q (TOBNQ) respectively, of the manufacturing firms at 1% significant levels. The study therefore, recommends that CEO characteristics should not be independently sought for, but jointly as complementary components in individuals being considered for the CEO position. Additionally, appointing a female CEO should not be a fulfilling task, but a woman could be made the CEO if she possesses other complementary attributes, required for driving the firm towards greater performance and value, as would do by a male counterpart.

Authors: Nisicha Theresya Grace , Marpaung Marlin Steffi
Published: January 2023

Code-switching has become a characteristic or pattern of communicative change in contemporary generation. This effect occurs in Indonesian culture, which was acculturated with a foreign language, and code-switching can let them construct a simple phrase to declare that is not available in their own language. It is frequently heard on various national entertainment shows, by content producers on YouTube, and in podcasts. The main objective of this research paper is to explicate which type and kind of code switching is more widespread when the two speakers speak in Deddy Corbuzier's podcast. This study collects data using qualitative methodologies for sociolinguistic phenomena and documentation procedures. In this study, Poplack theory is applied to examine the different forms of code switching. The authors encountered three patterns of code-switching: Tag-switching, inter-sentential code-switching, and intra-sentential code-switching are part of code-switching. Based upon the outcomes of the data acquired from the Deddy Corbuzier Podcast, the researchers summarize that the form of switching code that is most commonly employed in communication is Inter Sentential Code Switching.

Authors: Soelistyowati Rr Dinar
Published: January 2023

Currently we live in the era of VUCA (Volatility, Uncertainty, Complexity, Ambiguity) where social change is very fast and unpredictable. It is influenced by many factors that are difficult to control, truth and reality are very subjective. In the past, we were taught to love the nation and country by diligently following the flag ceremony at school and other rules that had been prepared by the teaching materials produced by the government. But now the millennial generation can show their loyalty by presenting artistic and cultural attractions that can take various forms. Psychologically the condition of today's young generation is very different from the previous younger generation. The previous younger generation was synonymous with obeying rules, ethics and other polite attitudes. While the current generation is more open, expressive & democratic. This research wants to see from the psychological aspect of communication how the current millennial generation responds to vuca in its obligations as a nation and a state.

Understanding the Characteristics of the Heatwaves using Temperature as the Only Variable –A Case Study on the Heatwaves in 1994 in South Korea
Authors:   University of Peradeniya, Chandrasekar Sewwandhi S. K , Han Kwon Hyun- ,   Sejong University
Published: January 2023

Acutely warm weather coupled with extreme weather variables or latent cooling due to a deficit of soil moisture could generate heatwaves.South Korea is highly susceptible to heatwaves that occur annually in different intensities and cause devastating impacts. This study aimed to identify the characteristics of the heatwaves, especially focusing on one of the most severe heatwaves observed in 1994 in South Korea using only temperature as a variable. The summer season, June to September (JJAS), was selected for the study because heatwaves were prominent during the summer in South Korea. The maximum and minimum daily temperatures were collected from the 67 meteorological stations located in South Korea. The mean daily 95thpercentiles of the temperatures were assessed to identify the heatwave durations and the intensities. In 1994, the 15 stations recorded their highest heatwave durations, and durations varied between 48 to 66 days in the JJAS season. Busanstation recorded the highest heatwave duration in 1994, which persisted for 66 days or throughout half of the season. Further, it was interesting to identify that coastal meteorological stations were most vulnerable to heatwaves in South Korea. However, the relationship between temperature intensities and heatwave duration for coastal cities showed statistically low significance. Furthermore, it is identified that the daily maximum temperature was most influential in the occurrence of heatwaves in both thecoastal and mainland meteorological stations, except for Pohangand Ulleungdo. Therefore, the characteristics of heatwaves observed in 1994 in South Korea were identified using temperature as the only variable. Furthermore, a study on the dynamic atmospheric oscillations due to heated waves in coastal regions of South Korea over characteristics of heatwaves observed in South Korea is suggested.KEYWORDS: Heatwaves, South Korea, Temperature, 95thpercentile.

Published: January 2023

Sentinel-2 satellite data has been used for forest cover monitoring for almost five years. Mapping with Sentinel data will be a cost-effective solution for Sri Lanka, where the lack of updated land cover maps with high spatial resolution is a significant challenge in the land resource management of the country. A study area of about 5,000 km2 located in southeast Sri Lanka was selected for this study. Agricultural lands, forests including Yala national park, and villages with perennial crops make up the region. A Level-2A Sentinel-2 image with less than 10 percent cloud cover was used in the European Space Agency's (ESA) SNAP software version 8.0.0 for image processing and the forest cover of the study area was mapped through the Random Forest classifier (RFC). Normalized Difference Vegetation Index (NDVI) is also calculated as a Sentinel product to support RFC output. For RFC, ground truth data were collected through the reference of Google Earth high-resolution data. The classification accuracy was assessed using the Google Earth image as the reference dataset. Furthermore, RFC results were compared with NVDI greenness values. The classification accuracy was calculated using a confusion matrix (error matrix) through randomly selected 100 sample points. The overall accuracy of the land cover map was 85 percent, with a 96 percent accuracy for forest cover identification. The study found RFC as an effective method to isolate forest cover in Sri Lanka.KEYWORDS: Sentinel-2, Random Forest Classifier, Land cover classification, Land cover mapping, Normalized Difference Vegetation Index.

ATYPICAL INTERPRETATION OF MEDULLOBLASTOMA
Authors: Panda Rabinarayan , Paul Pratosh , Mishra Sanjib , Mishra Sudhanshu
Published: January 2023

Introduction: Medulloblastoma is a midline posterior fossa mass that typically develops from the vermis in children. It shows up on a CT scan as a hyperdense, homogeneously enhancing mass and is linked to the clinical profile of posterior fossa syndrome. Although this distinct clinical-radiological pattern is regarded as "typical," medulloblastomas frequently do not follow the normal clinico-radiological pattern.
Methods: To identify the abnormal clinical-radiological features, 28 patients were retrospectively analyzed and 12 cases were prospectively studied. Only 21 of the 40 patients showed the typical radiological feature of a hyperdense homogeneously enhancing mass, while the other four had hypodense nonenhancing masses, 12 had cystic alterations, and five had calcifications in their tumors. Three patients arrived with tumors in the cerebellopontine angle cistern, which is a rather rare position.
Results: Patients who underwent follow-up for a minimum of 6 months and a maximum of 1 year returned with metastases in very odd places. There were 2 patients who had a cervical intramedullary metastasis, and there were 4 occurrences of metastases in the frontal and subfrontal area. One year following final surgery and ventriculoperitoneal shunting, abdominal metastases and ascites occurred in 3 individuals. But after surgery, each of these 3 patients had had a complete course of craniospinal irradiation.
Conclusion: There were other cases that had atypical clinical, radiological, and metastatic patterns.
ID PROTEIN EXPRESSION PATTERN IN MEDULLOBLASTOMA
Authors: Panda Rabinarayan , Paul Pratosh , Mishra Sanjib , Mishra Sudhanshu
Published: January 2023

Id proteins, also known as inhibitors of DNA binding or inhibitors of differentiation, are upregulated in a variety of neoplasms, especially in conjunction with high-grade, poorly differentiated tumours, whereas differentiated tissues have little to no Id expression. The helix-loop-helix (HLH) family of transcription factors, which the four Id genes are part of, controls transcription by binding to and sequestering HLH complexes. By doing immunohistochemistry utilising a medulloblastoma tissue microarray with 44 distinct medulloblastomas and 10 normal control cerebella, and testing antibodies specific for Id1, Id2, Id3, and Id4 it was hypothesised that Id proteins are overexpressed in medulloblastomas.
A semi-quantitative staining score that considered staining intensity and the percentage of immunoreactive cells was implemented. Id1 was not found in medulloblastoma or normal cerebella, but it was strongly expressed in the endothelial nuclei of tumour arteries in 77% of tumours. In medulloblastoma, Id2 expression was more prominent than in normal cerebella (median staining score: 3). Id3 expression was seen in some neurons of the growing cerebellar cortex, but it was dramatically upregulated in tumour endothelial cells and medulloblastoma (median labelling score: 11).
Id4 was not expressed in either tumour cells or normal cerebella. By modifying the expression of essential cell cycle regulatory proteins in favour of cell proliferation, Id2 or Id3 overexpression induced proliferation in medulloblastoma cell lines. This research demonstrates that enhanced Id2 and Id3 expression in medulloblastoma may play a role in tumour cell proliferation and survival and that Id1 expression in endothelial cells may contribute to angiogenic processes.

What’s in it for me? Compliance toward change comes with Personal Valence
Authors: Fatima Mehreen , Riaz Amir , Mahmood Hafiz Zahid
Published: January 2023

For today’s organizations, survival and growth depend on responding quickly to the changes occurring in the environment. Effective execution of change programs depends to a considerable degree on the extent to which their employees value change. Therefore, making them understand that change is beneficial for them is imperative for enactment of any change program. Grounded in the theory of planned behavior, this research aims at examining the direct impact of personal valence on employees’ compliance toward change. Further, change readiness and commitment to change are proposed as sequential mediators between personal valence and compliance toward change. Self-administered questionnaires were utilized to collect primary data. The selected 583 respondents were officer-ranked employees in financial institutions, as well as media and telecom in the Punjab province and Islamabad, Federal Capital Territory of Pakistan. To test the hypotheses, PROCESS macros are employed for measuring the effects of mediation. The findings supported the hypothesized relationships of the study that personal valence directly influences compliance toward change. Moreover, change readiness and commitment to change also mediate, in sequence, the relationship between personal valence and employees’ compliance toward change. These findings establish that for the effective implementation of change programs in an organization, it is indispensable that employees must perceive the change program as beneficial and valuable to them. Limitations and future research avenues regarding this study are also discussed accordingly.

Isolation and Characterization of Microorganisms From Scoby (Symbiotic Culture of Bacteria and Yeast) During Kombucha Fermentation
Authors: Yuliana Eva , Permana Anita Herawati
Published: January 2023

Kombucha is made by fermenting tea with sugar solution using SCOBY (symbiotic culture of bacteria and yeast). Kombucha fermentation is divided into several stages, such as the conversion of sugar into ethanol, the conversion of ethanol into acetic acid, and the conversion of acetic acid into carbon dioxide. Thus, several types of unique microorganisms must be involved during kombucha fermentation. Our previous research has reported that culturable microorganisms from kombucha drink (liquid phase) were all bacteria. Furthermore, in this research we investigated culturable microorganisms from the SCOBY itself. During kombucha fermentation, SCOBY sheets were cut (about 1×1 cm) each day using a sterile knife. SCOBY slice was enriched in Potato Dextrose Broth and incubated at 37 °C for 24 hours. The enriched culture was inoculated into Plate Count Agar and incubated at 37 °C for 24 hours. Four different colonies, named isolate (a), (b), (c), (d), were collected during 14 days of kombucha fermentation. The suspected colonies of bacteria were cultivated in Nutrient Agar, while the suspected colonies of mold or yeast were cultivated in Potato Dextrose Agar. The characterization results suggested that isolate (a) has close characteristic to Acetobacter genus (gram negative, short rod, does not produce endospore), meanwhile isolate (b) is gram negative, long rod, and produces endospore. Isolate (c) was suspected as mold, and isolate (d) was identified as yeast.

Authors: Natarajan Muthu Mekala , Chinnasamy Balamurugan , Bejaxhin Alphonse Bovas Herbert
Published: January 2023

Construction, processing, biomedical instruments, electronics, automobiles, and aerospace widely use thin-wall parts. Mostly, these thinwalled parts are machined using either a peripheral milling machine or an end milling machine with the help of fixtures. In this study, three different material thin-walled parts (i.e., Inconel 718, AISI 316L, and Al 6061) are machined in end milling using a newly designed fixture with cylindrical heads, and the surface roughness and deformation with different machining parameters are compared. The optimum values of the machining parameters feed, speed, and depth of cut have been found to improve the surface roughness of thin-walled plates by arresting the deformation using the proposed fixture. Analysis of variance (ANOVA) results show that the speed is the most influential parameter in the case of displacement for AISI 716L and Al 6061, feed is the most influential parameter in the case of surface roughness for Inconel 718 and AISI 716L, and speed is the most influential parameter in the case of displacement and surface roughness for Al 6061. The use of fixtures provides a significant reduction in the deformation and surface roughness during the machining in end milling machine.

Math prospective teachers must be able to think creatively and solve problems. The study looked into preservice teachers’ creative thinking and problem-solving abilities in statistics. The investigation was guided by a correlational design in a public university in the Philippines. Stratified random sampling was used to select the 103 study participants from two teacher education programs. Through google forms, data were collected using Torrance et al. (2008)’s tests of creative thinking and researcher-made statistics problem test. The findings revealed that preservice teachers have commendable creative thinking, particularly fluency, flexibility, and elaboration skills, but they lack problem-solving skills in statistics, specifically with central tendency, dispersion, and position measures. The correlational analysis revealed no link between creative thinking and problem-solving. Still, creative thinking and problem-solving courses are recommended to help preservice teachers develop their fundamental skills as mathematics educators.

Knowledge of the morphometric relationships of Amazonian species can contribute to forest-sustainable tree management. The objective of this study is to describe and evaluate the morphometric relationships of 10 tree species from a tropical forest managed in a second cutting cycle. Morphometric data were collected in a forest located in the municipality of Itaúba (“Mato Grosso” state – MT, Brazil). In general, the DBH, Total Tree Height, and commercial morphometric parameters were similar for the species, except for copaiba, which presented a small value for minimum DBH, and low regeneration of the species in the area. The evaluated species showed a high value of Canopy Shape (average CS = 1.28) and the value of Canopy Proportion was 44.87%, slightly lower than those found in the literature. In the Salience Index, the data found ranged from 14 to 36, a result close to that expected for tropical forests. The average Slenderness Ratio (SR) observed in the area indicated that the trees are relatively robust and less prone to crown and trunk breaks. For the Salience Index, it was observed that the species showed a reduction of the index with the increase of DBH. There was a positive response for the relationships between variables evaluated, with 23.4% for the Canopy Diameter x DBH ratio (i.e., CD × DBH), 5.6% for the Canopy Ratio × DBH (CR × DBH), and 18.8% for the Total Height (HT × DBH). The morphometric correlations obtained low results (R²: 0.234; 0.056 and 0.188 respectively). However, the average correlation between Total Tree Height and DBH was expected to be higher due to changes in tree growth due to the intervention carried out in the forest.
Disentangling the Rhythm from the Melody: What Really Causes the Mozart Effect?
Authors: Meares Madison , Goodmon Leilani
Published: January 2023

The Mozart Effect refers to enhanced spatial ability following listening to 10 minutes of Mozart music (Rauscher et al., 1993; Rauscher et al., 1995; Rideout & Taylor, 1997). However, many researchers have not been able to replicate its benefit on cognitive functioning (McKelvie & Low, 2002; Steele et al., 1999) while other researchers provide evidence that the intellectual benefit may not be due to the music exclusively, but to changes in mood and arousal levels (Cacciafesta et al., 2010; Steele, 2000; Lints & Gadbois, 2003; Thompson et al., 2001). Furthermore, it is unclear whether this Mozart Effect is the result of the melody or the rhythmic pattern of the Mozart music (Shi, 2020). Therefore, the purpose of the current study was to determine which musical element (i.e., melody or rhythmic pattern) of Mozart’s sonata (Mozart Sonata for Two Piano’s in D major, K. 448) causes the spatial performance enhancement and to determine if the benefit generalizes to another type of spatial ability, specifically 2D mental rotation. In order to disentangle the effects of the rhythm from the melody, we exposed participants to a Lo-fi (i.e., reproduction of audio that highlights the rhythmic pattern of Mozart’s sonata with a slower tempo) version of the Mozart sonata that maintained the rhythmic pattern of the sonata but differed in melody. Inconsistent with hypotheses, neither version of the Mozart music significantly improved mood and arousal; however, the mood/arousal benefits approached significance while the control music, Albinoni’s Adagio in G Minor for Organ and Strings, significantly decreased mood/arousal. Thus, the current results provide some evidence that the rhythmic pattern (as opposed to the melody) of the Mozart sonata increases mood/arousal. However, the rhythmic pattern failed to produce better cognitive functioning (e.g., faster 2D mental rotation) in either its original form or the Lo-fi form.

One measures of progress for a country is marked by increased economic growth, this is calculated from the increase in the amount of production of goods or services in the economy so that it increases the per capita income of the population in a country. economics growth can be achieved by specializing in the production of goods and services. Specialization can occur if there is a large market to accommodate production, a market exists if a country conducts international trade. The purpose of this study is to determine the effect of rice commodity prices and inflation on the import value of North Sumatra Province. This study uses a quantitative approach. The data used is the number of exports, imports and commodity prices in North Sumatra Province. Methods of data analysis using data analysis techniques used are descriptive techniques and path analysis (path analysis) with the application of multiple linear regression models with the help of the SPSS program. the results of multiple linear regression tests in the term the regression coefficient is positive indicating that an increase in rice commodity prices will increase the value of imports. The regression coefficient is negative indicating that an increase in inflation will reduce the value of imports.
