Published: July 2023

Transferable skills are abilities and knowledge that can be used in various jobs and career paths and is related to the career development of students in the era of disruption. School counsellors need to understand student profiles related to these basic skill sets in order to be able to design career development programs that are relevant to today's career dynamics. This study aims to construct a transferable skill scale that can be used as a guidance and counselling assessment tool for student career development. The construction of this scale goes through the stages of 1) aspect construction based on literature studies, 2) item creation, and 3) pilot test. The construct validity test used Confirmatory Factor Analysis (CFA). The results of the CFA show that several dimensions of transferable skills require modification of the model until a fit model is obtained.. Thus the scale has a suitable model for measuring transferable skills, which consist of aspects of 1) Communication Skills (7 items), 2) Management Skills (9 Items), 3) Numerical Skills (5 Items), Creativity Skills (6 Items), Social Skills (6 Items), Critical Thinking Skills (5 Items), and Business Skills (6 Items).

Authors: Kaur Ravneet , Gupta Parul , Agarwal Vandana , Mathur Anee
Published: July 2023

Urothelial neoplasms can be classified as non-invasive & invasive lesions. The major prognostic factors are degree of differentiation and depth of invasion in urothelial tumors. Ki-67 is a non- histone nuclear protein marker of cell proliferation which is encoded by MKi-67 gene in humans. This study evaluates and correlate immunohistochemical Ki-67 expression in Non-invasive & Invasive urothelial neoplasm. This retrospective study is done in the Department of Pathology of L.N. Medical College and J.K. Hospital, Bhopal. Urothelial Neoplasm cases diagnosed from January 2019 to January 2022 were included, & relevant clinico-pathological data and their Ki-67 Labelling Index was evaluated & correlated. Total 60 cases were studied, 30 had invasive carcinoma whereas, 30 had non-invasive neoplasm. Ki-67 expression (>13%) was seen maximum in invasive cancers i.e 40% cases, whereas (<13%) was seen maximum in non-invasive neoplasms i.e 38.3%. A statistically significant expression of Mean Ki-67 Labelling Index was observed that increased from papilloma to PUNLMP, Non- Invasive urothelial neoplasm Low grade & High grade in non-invasive urothelial neoplasm (p<0.001), and from lamina propria invasive to muscle invasive urothelial cancers (p=0.013). A Higher tumor proliferation of greater than 13% was significantly related to greater tumor size (p=0.04). Ki-67 labelling index being a measure of tumor proliferation is related to tumor histological grade. Large urothelial tumor size was associated to high Ki-67 LI and was not strongly associated with age and gender. Therefore Ki-67 expression can be used as Diagnostic & Prognostic marker in urothelial tumors.

Synthesis and study of corrosion behavior of terephthalaldehyde-derived schiff base for low-carbon steel in HCl: experimental, morphological and theoretical investigation
Authors: Betti N. , Al-Azzawi W.K. , Alamiery A.
Published: July 2023

In the present investigation, corrosion inhibition assays of the terephthalaldehyde-derived Schiff base of low-carbon steel have been performed in a 1.0 mol L−1 hydrochloric acid solution. Weight loss measurements were applied to investigate the corrosion inhibition efficacy of Schiff base as an inhibitor. The highest inhibitive efficacy was achieved at a select concentration of 500.0 ppm for the tested inhibitor. The Langmuir adsorption isotherm model was applied to portray the adsorption inhibition mechanism. The variation in the activation energy value in the presence of synthesized inhibitor indicates the types of interactions between the inhibitor molecules and low-carbon steel surface. Scanning electron microscopy analyses proved the adsorption of inhibitor molecules on the low-carbon steel surface and through form a film that protects the metallic surface from corrosion. Furthermore, the relationship between inhibitive efficacy and the inhibitor molecule structure was studied theoretically through density functional theory (DFT). The experimental and theoretical findings reveal compatible harmony between them.
Multipliers based on net income as an indicator of the investment attractiveness of domestic vertically integrated oil and gas companies
Authors: SHIMKO Oleg V.
Published: July 2023

Subject. This article focuses on the market-capitalization-to-net-income ratios of the twenty five leading publicly traded oil and gas companies within 2008 through 2018.
Objectives. The article aims to identify key trends in the changes in the values of market-capitalization-to-corporations'-net-income ratios of the oil and gas companies, as well as identify key trends in their change within the studied period, and identify the factors that caused those changes.
Methods. For the study, I used the methods of comparative, financial and economic analyses, summarizing financial reporting data.
Results. The article finds that the studied multipliers based on net income of shareholders are of little use for assessing the value of oil and gas companies due to the volatility of oil prices. Integrated corporations are not as dependent on oil prices as independent companies. Net income can be affected not only by a decrease in revenue, but also by the cost of impairment, revaluation or write-off of assets in the event of a fall in oil prices, and therefore, the use of the multipliers is advisable in case of high profitability in the industry. Net income may also be affected by income and expenses that are not related to operating activities. This factor should be taken into account when choosing an analogue company. It was revealed that the characteristic features of the market capitalization of companies in the industry are reflected in the indicators, which include the provision with proved reserves and level of debt. It is better to use an enterprise value indicator instead of market capitalization in a multiplier if there is a noticeable difference in debt burden.
Conclusions and Relevance. To apply the multipliers based on net income is very difficult in the face of declining profitability and increasing debt burden in the stock market sector of the global oil and gas industry. The findings can help appraise the value of oil and gas assets as part of a comparative approach and decide on actions for raising the market capitalization of publicly traded oil and gas corporations.

Authors: Midde Adiseshaiah , Maruvada Sailaja
Published: July 2023

One of the most crucial thing to safeguard the network against malicious activities is security and the network devices must be able to classify packets. The firewall applications benefit greatly from the architecture of the packet classification engine that is given in this research work. A tree-based approach is used to systematically analyze each field in a packet header, leading to a more secure system. The Packet Classification Engine (PCE) is configured to evaluate Ethernet packets based on the source IP address, destination IP address, source port, destination port, and protocol aspects in the packet header. The PCE shows that the typical clock frequency from input to output is 13 clocks per second. The architecture is extremely rapid, reliable, and adaptable and can make good use of the tree based algorithm's advantages. The proposed architecture has achieved high throughput of 538 MPPS with less energy of 10.6 nJ at low latency of 62 ns. The PCE must have a rapid and reliable FIFO buffer to work effectively. A FPGA (Field Programmable Gate Array) device is being utilized to filter Ethernet packets using the proposed PCE.

Las propiedades funcionales de las proteínas son de importancia en la industria alimentaria, ya que influyen en las características del alimento del cual forman parte y por ende en la aceptación del consumidor. Específicamente, las proteínas de las leguminosas son relevantes por su contenido de aminoácidos esenciales, sin embargo, no todos los géneros y especies de leguminosas han sido caracterizados, como es el caso del género Vigna. Por lo tanto, el objetivo del presente trabajo fue evaluar el efecto del tratamiento térmico sobre las características tecno-funcionales de concentrados proteínicos de Vigna umbellata y Vigna unguiculata. Los resultados indicaron que el tratamiento térmico no influyo en las propiedades de hidratación (capacidad de retención de agua y capacidad de absorción de agua), posiblemente debido a la solubilidad, ni en la capacidad de absorción de aceite. El pH 12 tuvo mayor actividad espumante, y el tratamiento hidrotérmico provocó una mayor estabilidad espumante a los 30 y 120 min. Acorde a los resultados obtenidos, el tratamiento térmico no genera cambios importantes en las características tecno-funcionales de los aislados proteínicos de las dos especies del género Vigna, sin embargo, el pH si es un parámetro de importancia en algunas propiedades.

Selais bungkuk (Hemisilurus heterorhynchus Bleeker) is one of catfishes which is a member of family Siluridae and order Siluriformes. Selais bungkuk is an endemic fish in Riau Province. The scientific study of this fish is still limited including DNA barcoding study. This research aims to analyze the DNA barcode of cytochrome b (cytb) on selais bungkuk. Methods included colleting the fishes from Kampar River (three individuals) and Tapung River (three individuals); total DNA extraction from the muscle; electrophoresis, PCR, sequencing; and bioinformatics analysis. In this study, cytb DNA sequences were obtained from the six individual fishes studied with a size of 339 bp. The six sequences have been registered at GenBank with registration numbers MH633750, MH633751, MH633752 from Kampar River, MH633753, MH633754, and MH633755 from Tapung River. The BLASTn analysis showed that the selais bungkuk fish had the highest similarity of 92.63% with H. mekongensis and the lowest (90.00%) with selais janggut (Kryptopterus limpok). There were three nucleotides that characterize the selais bungkuk fish based on the cytb sequence such as nucleotide number 205, 229, and 280. The cytb sequence can distinguish groups of catfish separately based on their species. Conclusions and recommendations, the cytb sequences obtained in this study are the first to be reported in selais bungkuk fish and can be used as a reference for identifying this species.

Jalur pedestrian merupakan salah satu elemen pembentuk suatu kota yang berupa ruang terbuka publik sebagai wadah bagi aktivitas dan sirkulasi pejalan kaki. Keberadaan jalur pedestrian sangatlah penting untuk menunjang aktivitas perkotaan sehingga efektifitas fungsi dari jalur pedestrian juga perlu diperhatikan.Kawasan studi berada pada koridor Jl. A.A. Gede Ngurah merupakan bagian dari Kawasan Bisnis Cakranegara (KBC) dan dikenal sebagai pusat kawasan bisnis Kota Mataram, sehingga potensi adanya mobilitas dan aktivitas berjalan kaki cukup tinggi. Potensi ini sayangnya, tidak didukung oleh perilaku spasial masyarakat yang cenderung membentuk pola klaim ruang tertentu terhadap jalur pejalan kaki sehingga kemudian berdampak pada terganggunya fungsi dari ruang tersebut. Penelitian ini dilakukan untuk mengetahui bagaimana fenomena klaim ruang publik yang terbentuk pada kawasan studi. Metode penelitian yang digunakan adalah metode deskriptif kualitatif dengan teknik observasi untuk mengamati fenomena yang terjadi di lapangan. Secara umum dari hasil penelitian dapat disimpulkan bahwa klaim ruang masyarakat sekitar kawasan studi mengarah pada perilaku teritorialitas dengan pola ekspansi teritorial dan privatisasi ruang publik untuk kepentingan pribadi.

Comparison is the thief of joy? Introducing the Attitudes towards Social Comparison Inventory
Authors: Schlechter Pascal , Meyer Thomas , Morina Nexhmedin
Published: July 2023

Social comparison has a significant impact on individuals’ motivation, affect, and behavior. However, we lack a scale that captures individual differences in attitudes towards social comparison. To address this gap, we developed the Attitudes Towards Social Comparison Inventory (ASCI) drawing on existing scales tapping into metacognitive beliefs about worrying, self-motives, beliefs about emotions, and the general comparative-processing model. We examined the psychometric properties of the ASCI in a longitudinal study (N = 1084), and a second (N = 550) and third cross-sectional study (N = 306). Through exploratory and confirmatory factor analyses, we identified a 12-item two-factor solution capturing positive and negative attitudes towards social comparison. The ASCI demonstrated measurement invariance across gender, time, and language (English/German). The two factors were differentially and longitudinally associated with relevant constructs including social comparison, metacognitive beliefs about worrying, depression, self-concept clarity, envy, and self-esteem. The ASCI enables thorough investigations of social comparison processes.

Last year, I already shared some thoughts on what I wanted (including an independent body to police compliance and legal enforceability of the rules), but the focus was on principle. I said that the rules should be non-discretionary, evidence- based, continually monitored, and properly enforced. However, I did not suggest what precise measures should be adopted. I am doing that now.
