Evaluating the Dynamics of Capital Structure, Corporate Governance, and Bank Performance: A Case Study of Listed Banks in Ghana
Authors: Coleman Winnifred
Published: October 2023

This study explores the interconnections among capital structure, corporate governance, and bank performance in listed banking institutions in Ghana, utilizing a comprehensive scorecard approach to assess corporate governance compliance. We identify a bi-causal link between corporate governance and stock returns, indicating that changes in corporate governance practices lead to subsequent fluctuations in stock returns. As stock returns rise, banks can attract more investors, reducing their debt and leverage (debt to equity ratio) ratios. Regarding capital structure and bank performance, we find no evidence supporting the notion that the equity ratio causes changes in stock returns, but a causal relationship exists in the opposite direction. Stock returns impact the proportion of total assets attributed to equity, as higher returns attract investors, facilitating bank expansion through new share issuance. Furthermore, we detect a bi-directional causality between stock returns and the debt ratio. Lastly, we observe a unidirectional causality where the debt to equity ratio does not cause changes in stock returns, but stock returns influence the debt to equity ratio. Rising stock returns enhance equity value, prompting banks to increase equity at the expense of debt, thus boosting operational funding through retained earnings. These findings illuminate the complex relationships between capital structure, corporate governance, and bank performance, offering valuable insights for financial practitioners and policymakers.

DECOLONIZING ANGLOPHONE EAP INFLUENCE IN THE EUROPEAN HIGHER EDUCATION CONTEXT
Authors: Fedorova Natalia
Published: October 2023

It is widely known that English teaching practices are largely rooted in colonialism and linguistic imperialism – the belief in the superiority of the Western teaching methods and linguistic norms established in such countries as the UK and the US. The current trend to decolonize English teaching has been gaining momentum for over three decades but has not entirely penetrated into the mainstream teaching of English, with English for Academic Purposes not being an exception. Relatively little focus has been placed in the research onto non-English speaking contexts with the purpose of analysing the current state of EAP provision at universities and gauging the influence of the native-speakerist academic English norms on EAP students’ writing. In the case of the EU context, it may be particularly pertinent to investigate the potential influence that Brexit might have had in terms of rejecting the imposition of the Standard British English norms and associated teaching approaches. This paper is meant to be a reflection with an attempt to stimulate the discussion of EAP teaching practices and academic discourses in the EU higher education in the post-Brexit era. It will consider the issues in the EAP provision in the EU with the example of Portuguese HE and will reflect on the native-speakerist tendencies within the academia and ways to tackle the dominance of the Anglophone norms. This paper hopes to contribute to the argument in favor of the decolonization of EAP teaching practices in non-English speaking contexts, as decolonization can help foster a more equitable and inclusive world.
EVALUATION OF STUDY SKILLS INTEGRATION INTO OMANI SECONDARY SCHOOL CURRICULUM

Published: October 2023

Study skills are considered critical in both the academic and professional life of a student. This study focusses on the extent to which secondary school students in Omani public schools possess study skills and how these are integrated into their English language textbook. The study explored i) the study skills profile of students in terms of college readiness, ii) the correlation between students' academic performance and study skills, and iii) the types of study skills embedded in the ‘Engage with English’ coursebook and workbook used in Grade 12. For this purpose, an adapted version of the pre-tested Study Skills Inventory developed by Dennis Congo was administered to 162 secondary school students. The results revealed that the students are relatively strong in the skills of memorising, test preparation, and concentration; however, most students lack fundamental study skills such as reading, critical and creative thinking, and time management skills. With respect to the correlation between study skills and academic performance, a bivariate correlation between the individual high school percentage and skills was performed using SPSS. The results showed a weak correlation between study skills and student performance for most of the skills except concentration which revealed a strong positive correlation with a Pearson value of 0.72. The document analysis of the textbook was conducted in alignment with the same inventory. The analysis revealed that although the textbook covers reading and memorising skills, other important skills including note-taking, test preparation, time management, and critical thinking skills are not targeted adequately. Although the student sample size is not large enough to generalise the findings of the study and only one textbook used by Grade 12 students was analysed, the authors conclude that there is an urgent need for the inclusion of study skills in the Omani public school curriculum to enhance students’ transition to higher education and subsequently, their professional success. The curriculum designers and decision-makers should consider embedding study skills more extensively in the curriculum during the next review cycle.

Authors: Al Damen Tareq , Cambrdige Karleen
Published: October 2023

-reader is an online extensive reading tool that motivates learners to read extensively and ‎autonomously. Through its online quizzes, M-reader tests students' comprehension of ‎graded readers and provides evidence that they have read and understood their reading. ‎Today, M-reader is used by several academic institutions around the world to facilitate ‎their extensive reading programs. However, concerns have been raised about academic ‎integrity in connection with M-reader. For instance, one of the foremost challenges of ‎administering M-reader is students taking quizzes on behalf of others. 229 first-year ‎university students enrolled in Sultan Qaboos University's Foundation Program (FP) in ‎Oman participated in the current study. The purpose of this paper was to investigate the ‎effectiveness of the measures implemented to reduce cheating on M-reader, as well as to ‎discover what students perceive as academic integrity on M-reader. To gauge the efficacy ‎of M-reader in maintaining academic integrity, participants completed an online ‎questionnaire and samples of the various measures were collected and analyzed. The ‎findings of the study revealed that the measures taken to mitigate academic integrity on M-‎reader were ineffective. The findings also indicated that M-reader appeared ineffective in ‎maintaining academic integrity among students. Additionally, the study identified how ‎students perceive the measures taken to mitigate cheating. Moreover, the study suggests ‎ways to improve the effectiveness of M-reader in terms of academic integrity.‎

Published: October 2023

.O número 42 da Revista Trabalho Necessário é publicado em uma conjuntura de grande gravidade política e social no país, que expressa o avanço da estratégia ultraliberal e ultraconservadora frente às políticas sociais e a organização classista da extrema direita, via fascistização da sociedade. O empresariamento da educação, para os setores dominantes, além de representar a ação organizada de disputa do fundo público e incentivo à privatização no campo educacional pelos setores rentistas, também configura a destruição do projeto de escola pública forjado nas lutas sociais. Destacamos, por sua contribuição histórica a esse projeto de escola pública, a figura militante do educador socialista Florestan Fernandes, cujo aporte à leitura da particularidade do capitalismo dependente na formação social brasileira é irrefutável para a compreensão das contrarreformas também como marca do caráter não-clássico da revolução burguesa no Brasil.

Published: October 2023

Seiring dengan perkembangan teknologi yang semakin pesat, buah-buahan banyak dikemas dalam kaleng. Buah kemasan kaleng merupakan makanan yang sering dikonsumsi oleh manusia pada saat ini. Penyimpanan buah kemasan kaleng dalam waktu yang lama dapat menyebabkan terjadinya migrasi logam berat terhadap buah yang ada di dalam kemasan. Pada penelitian ini sampel yang digunakan yaitu 3 jenis buah-buahan dalam kemasan kaleng masing-masing dengan lama penyimpanan yang berbeda. Preparasi sampel dilakukan menggunakan metode destruksi basah dengan menambahkan campuran HNO3 pekat 65% dan H2O2 15% (3:1). Kandungan logam Fe, Zn, Pb, dan Cd dalam sampel ditentukan menggunakan metode Spektrofotometri Serapan Atom (SSA). Nilai Indeks Risiko Kesehatan (IRK) didapatkan dari hasil perhitungan Asupan Logam Harian (ALH) per dosis yang disarankan oleh WHO. Nilai ALH diperoleh dari perhitungan konsentrasi logam dengan SSA, faktor konversi, dan rata-rata asupan logam per berat badan manusia. Kadar logam berat di dalam ketiga jenis sampel secara umum diperoleh Fe>Zn>Pb>Cd. Konsentrasi logam berat berbanding lurus dengan lama produk disimpan dalam kemasan kaleng. Semakin lama produk disimpan maka konsentrasi logam yang diperoleh semakin tinggi. Nilai IRK yang diperoleh dari pengujian sampel untuk logam Cd yaitu >1 dapat diasumsikan adanya potensi risiko kesehatan, sedangkan untuk logam Pb, Fe, dan Zn <1 yang diasumsikan populasi dinyatakan aman. Nilai TIRK yang diperoleh dari penambahan nilai IRK logam Pb, Cd, Fe, dan Zn, didapatkan hasil dari setiap sampel >1 dapat dinyatakan bahwa sampel yang diuji memiliki potensi risiko kesehatan terhadap manusia. Penelitian lebih lanjut diperlukan untuk memperjelas hubungan antara kontaminasi buah oleh logam berat dari kemasan kaleng.

Objek dari pembahasan ini untuk mengetahui cara mengatasi anak yang sudah terkontaminasi efek negatif dari literasi digital dengan metode penelitian kualitatif . Literasi digital yaitu kesangupan dalam memproses komputer untuk membaca dan menulis dalam format digital. Menurut kementerian komunikasi dan informatika menjelaskan mengenai literasi digital sebagai kemampuan yang dimiliki seseorang agar dapat menggunakan komputer dan mengakses konten yang ada di dalamnya dengan benar dan optimal.Tentunya dengan adanya kecakapan literasi digital ini dapat memudahkan anak dalam mengikuti proses perkembangan teknologi digital,dan juga dapat dimanfaatkan anak dalam belajar,kemudian dapat mencari tahu informasi yang baik dan bermanfaat dari berbagai sumber yang di dapatkan.Pada literasi digital terdapat juga pengaruh buruk dari media digital yang digunakan anak,sehingga berdampak buruk terhadap psikologis anak dalam pengungkapan diri melalui media sosial. Adapun akibat untuk psikologis lainnya dapat timbul terhadap anak yang menggunakan media sosial secara berlebihan akan menyebabkan gangguan kecemasan dan depresi. Kemudian ada beberapa masalah yang terjadi pada usia anak mengalami gemar akan gadget hingga ia sulit menghindari dan menghabiskan waktu dengan penggunaan tersebut, termasuk ketagihan game online ataupun bermain di media sosial. Dengan hal demikian yang merupakan sebagian akar permasalahan saat teknologi berkembang begitu pesat tanpa adanya pengawasan dari orang tua. Dari hal tersebut dapat mengakibatkan segala informasi bahkan konten di media sosial yang ia terima tanpa ada proses penyaringan, dan akhirnya informasi dan konten tersebut menguasai karakter anak,karena tidak didampingi oleh orang tua. Solusi untuk permasalah dan pengaruh media digital pada anak tentunya yang pertama perlu adanya pendampingan dan pengawasan orang tua,lalu anak tersebut harus diberi batasan dalam menggunakan media digital yang semakin berkembang,agar mereka sadar bahwa dalam penggunaan media digital itu sangat berdampak untuk perkembangannya.

Authors: Zahir Ahmad , Tambing Yohanis
Published: October 2023

Tujuan penelitian adalah untuk  mengetahui pengaruh   kombinasi  POC urin sapi dengan pupuk NPK (mutiara) terhadap pertumbuhan dan hasil tanaman mentimun, disamping itu perlakuan dengan cara mengkombinasikan kedua jenis pupuk tersebut  diharapkan dosis pupuk NPK lebih hemat oleh penggunaan POC urin sapi. Penelitian ini disusun menggunakan Rancangan Acak Kelompok (RAK) dengan 3 kali ulangan. Adapun perlakuan kombinasi POC urin sapi dengan pupuk NPK adalah sebagai berikut : P0 = Tanpa perlakuan (kontrol),  P1 = 10 g NPK/tanaman (50%) + 20 ml POC urin sapi, P2 = 10 g NPK/tanaman (50%)+30 ml POC urin sapi, P3 = 10 g NPK/tanaman (50 %) + 40 ml POC urin sapi, P4 = 20 g NPK/tanaman (75 %) + 20 ml POC urin sapi, P5 = 20 g NPK/tanaman (75 %) + 30 ml POC urin sapi, P6 = 20 g NPK/tanaman (75 %) + 40 ml POC urin sapi, P7 = 30 g NPK/tanaman (100 %) + 20 ml POC urin sapi, P8 = 30 g NPK/tanaman (100 %) + 30 ml POC urin sapi, P9 = 30 g NPK/tanaman (100 %) + 40 ml POC urin sapi. Setiap perlakuan diulang sebanyak tiga kali sehingga  menghasilkan 30 unit percobaan. Berdasarkan uraian diatas dapat disimpulkan bahwa perlakuan berbagai kombinasi urin sapi dengan pupuk NPK berpengaruh nyata terhadap jumlah daun pada umur 8 MST, luas daun, panjang buah, lilit buah tetapi tidak berpengaruh nyata pada pengamatan bobot segar buah. Kombinasi pupuk NPK 20 gram (75%) + 40 ml POC urin sapi per tanaman (P6) merupakan perlakuan terbaik terhadap pertumbuhan dan hasil tanaman mentimun. Ini berarti bahwa dengan menggunakan POC urin sapi 40ml dapat menghemat dosis pupuk NPK hingga 75%.
