Exploring with Dignified Justice Theory Substitute Imprisonment Fines for Corruption Convicts
Authors: Rivai Yasdan , Prasetyo Teguh , Leonard Tommy , . Azharudin
Published: October 2024

General provisions on criminal fines and their subsidiarity are contained in Article 30 of the Criminal Code. Article 30 paragraph (2) of the Criminal Code contains the possibility of substituting a fine with imprisonment. If the fine is not paid by the convict, this generally includes those convicted of corruption. The principle of imprisonment in lieu of a fine in Article 30 paragraph (2) is not found in Law of the Republic of Indonesia Number 20 of 2001 concerning Amendments to Law Number 31 of 1999 concerning the Eradication of Criminal Acts of Corruption (Corruption Law) . However, so far judges have used Article 30 paragraph (2) of the Criminal Code as the basis for deciding on imprisonment in lieu of a fine for those convicted of corruption. The problem is that the equivalence formula for one day of imprisonment is the same as a fine of seven rupiah 52 cents for those convicted of corruption in Article 30 paragraph (2) is outdated when compared to the current rupiah value. This equivalence formula is difficult to achieve the minimum fine for those convicted of corruption in the Corruption Law. For example, if the minimum fine is 50 million rupiah. If to achieve the equivalence of the fine one has to multiply seven rupiah 52 cents by the number of days in the eight months of maximum imprisonment, then it will not be possible to achieve equivalence according to Article 30 paragraph (6) of the Criminal Code. This study finds the principle of judicial independence in the Indonesian constitutional state as a solution to the unclear meaning of Article 30 paragraph (2) of the Criminal Code while waiting for the article to be abolished by the National Criminal Code.

Authors:   Assistant Campus Chief, Madan Bhandari Memorial College, Kathmandu, Nepal, Gautam Tara Prasad
Published: October 2024

Remittance inflows have surpassed other sources of foreign currency in many developing countries, with Nepal ranking among the top five recipients relative to its Gross Domestic Product (GDP). This study examines the impact of remittances on investment in Nepal, particularly in the Rupandehi district. With remittances growing at an annual rate of approximately 20%, they significantly influence the Nepalese economy. A survey involving 404 respondents explored how remittance funds are utilized across various sectors, including land purchases, housing reconstruction, share market investments, small business ventures, and electronic appliance acquisitions. The findings reveal that while there is no significant association between remittance amounts and land purchases or housing reconstruction, a significant link exists between remittance amounts and the types of houses purchased or reconstructed. Additionally, no significant association was found between remittance amounts and business investments or the purchase of electronic appliances and internet services. The study also indicated no significant relationship between migrant education and investments in land, housing, or the share market; however, a strong association was noted between the number of migrants and land purchases. These results suggest that while remittances contribute to various investment avenues, their impact varies across different types of investments. Keywords: remittance, investment, GDP, economic growth, migrants

Published: October 2024

This study attempts to identify and analyze “The errors in the written sentences produced by the students in grade 8 of Orr’s Hill Vivekananda School, Trincomalee”. The study begins with a systematic review of the concepts and theories concerning Error Analysis, which sets the platform for the theoretical base. Subsequently, the Error Analysis focuses on finding the syntactical errors under the selected grammatical categories while searching for the possible reasons causing errors. Eventually, the researcher suggests some of the complications involved in language learning and language teaching process. Understanding grammatical rules and applying them in sentences without making mistakes is what the teachers expect from the students in the school. However, it does not happen in the way it is expected. In other words, making grammatical errors can be assumed to be part and parcel of the language learning process. There are many linguistic aspects governing this learning process. Therefore, this research examines the type of errors the students make and why they make such errors in their writing. This dissertation is an eye-opener for teachers, with as they should understand the root causes of errors while attempting to find treatment for them. It is paramount that with teachers approach error corrections based on the student’s linguistic competence and their affective factors embedded with different socio-ethnic backgrounds. This error analysis has been undertaken with to with raise awareness among the teaching staff and help students produce better writing with fewer or no grammatical mistakes.

Authors: Hadayat Ali Hina , Javed Aftab Muhammad , Chaudhry Hira
Published: October 2024

This paper will discuss how assistive technology forms the basis of differentiation and support for students with special needs when conquering specific math learning difficulties. The Department of Special Education utilized a quantitative research design to collect data from 240 teachers through a structured, self-developed questionnaire. The use of simple random sampling maximized representative samples and minimized biases. We established the effects of AT in terms of differentiated instruction, increased student engagement, and an inclusive learning environment. Teachers estimated complex mathematical concepts using AT tools, such as virtual manipulatives and educational apps, as easier to understand and improve student confidence and participation levels. Overall, the findings indicate a need for continuous teacher training and resource allocation to effectively integrate these into a holistic classroom experience. The conclusion is that integrating assistive technology into education is a gateway to ensuring that every special need student receives quality learning in mathematics, thus equalizing access to education. Recommendations call for investment in professional development of the teachers, adequate resources for AT tools, and inculcation of AT provision in curriculum design. Further research should investigate the long-term effects of AT on students' achievement in other subjects.

Published: October 2024

Foreign capital inflows play a significant role in sustainable development of financial sector of any country. This study investigates the impact of foreign capital inflows (including remittances, foreign direct investment (FDI), foreign aid, and external debt) on the financial development of Pakistan. For empirical analysis, this study used linear and nonlinear autoregressive distribution lags (ARDL) techniques with time series data from 1972 to 2022. Findings reveal that FDI, workers’ remittances, and foreign aid support financial development, whereas external debt negatively impacts financial development. Moreover, there appear to be asymmetrical effects of FDI and external debt on the financial development in the long run which reduces to a nonlinear FDI-finance relationship in the short run. The outcomes of this study imply policies that encourage networks for FDI and remittances while discouraging external debt inflows to stabilize the financial sector.

Objectif : Déterminer la fréquence de la gonarthrose non opérée en rééducation et la corrélation entre les résultats fonctionnels avant et après rééducation.
Patients et méthodes : Il s’est agi d’une étude transversale à visée descriptive et analytique sur une période de deux ans dans le service de médecine physique et réadaptation (MPR) du Centre Hospitalier Universitaire de Bogodogo (CHU-B). Nous avons procédé à un recrutement exhaustif des patients souffrant de gonarthrose et ayant bénéficié d’une rééducation fonctionnelle sans interruption de programme durant la période de l’étude. Le programme de rééducation combinait plusieurs techniques de physiothérapie associées aux mobilisations articulaires, aux étirements, aux renforcements musculaires et à un travail proprioceptif. Les patients étaient évalués au plan clinique et fonctionnel, en début et en fin de programme de rééducation. L’estimation du coefficient de corrélation r a été utilisée, avec un seuil de significativité p≤ 0,05.
Résultats : Durant la période d’étude, 686 patients ont été admis pour une rééducation fonctionnelle. Soixante et onze (71) de ces patients ont bénéficié d’une rééducation fonctionnelle pour une gonarthrose non opérée, soit une fréquence hospitalière de 10,34%. Nous avons retenu 51 patients qui répondaient aux critères d’inclusion de l’étude. L’âge moyen des patients était de 58,65 ans ± 10,9 ans, avec des extrêmes de 38 ans et 78 ans. Le sex-ratio était de 0,18 soit 43 femmes et huit hommes. La gonarthrose était bilatérale dans 57% des cas et localisée à droite dans 33% des cas. Le score moyen de l’intensité de la douleur à l’Echelle Visuelle Analogique (EVA) était de 7,5 ± 1,55/10 à la consultation initiale et de 4,41 ± 1,7/10 en fin de programme. On observait une baisse significative de la douleur à l’EVA (p=0,0004 et r=0,65). Le score moyen de l’indice de Lequesne à l’examen initial des patients était de 13,09 ± 3.94 (très sévère) avec des extrêmes de 5 et 20. Le score moyen de l’indice de Lequesne en fin de programme de rééducation était de 9,37 ± 3,99 (sévère) avec des extrêmes de 3 et 18. On notait une amélioration significative de l’indice de Lequesne en fin de programme de rééducation (p=0,001 et r=0,53).
Conclusion : La gonarthrose non opérée est fréquente et vue tard en rééducation. La rééducation semble améliorer l’intensité de la douleur ainsi que la fonction du genou.

Materials and methods. The research was conducted on February 20-22, 2024 in the Kislovodsk National Park with the application of route landscape and climatic observations, as well as an assessment of human physical capabilities, using the example of a woman aged 31 years, height 165 cm and weight 56 kg. Results. Researchers of the Center of Biomedical Technologies (North-Caucasian Federal Research-Clinical Center) have developed two terrain cure routes: Route No 1 and Route No 2. According to the classification, the Route No 1 is considered difficult, the route’s length is 1600 m, angle of elevation – not more than 4°, completion time – 30-40 minutes, the pulse zone No 1 is mainly a light activity zone. The whole route runs through the lower part of the park and is protected from direct sunlight and, deep in the valley, from winds. The path is mostly flat, but has slopes in some locations. According to the classification, the Route No 2, developed from the “Orion” athlete rehabilitation and recovery center (North-Caucasian Federal Research-Clinical Center), is also considered difficult, the route’s length – 2600 m, angle of elevation – up to 13°, completion time – 50-60 minutes, the pulse zone No 1 is mainly a light activity zone. The route is also characterized by a long ascent and steep descent. Conclusion. The comprehensive analysis of the Kislovodsk National Park’s landscape modules proves that the landscape and climatic potential is high enough – 2.8 points out of 3.0 possible. It conditionally corresponds to the sparingly training effect on the human body, gives the possibility to conduct air therapy, heliotherapy, natural air and plant ion therapy in the low altitude conditions to prevent UV-insufficiency, increasing the resistance of the human body to physical stress and accelerating the recovery processes.

Complementary currencies are alternative units of exchange designed to complement official currencies. They have been used in both developed and developing countries to bridge societal and economic gaps that are inadequately addressed by official monetary systems. This paper explores the potential for Afghanistan to implement complementary currencies and the challenges it may face in this process. A qualitative research approach is employed, using analogical methods and content analysis to assess the potential advantages that complementary currencies could offer Afghanistan. The findings suggest that complementary currencies could significantly contribute to Afghanistan’s economic and social welfare, particularly in addressing gaps in resource distribution. The paper emphasizes critical success factors for the introduction of complementary currencies in Afghanistan, notably the need for political will, government support, legal frameworks, public awareness, and international cooperation. This study is the first to address the potential for complementary currencies in Afghanistan, highlighting its importance and forecasting its contribution to enhancing the financial system in the country.
