Published: February 2025

Purpose – The peace and stability of society are seriously threatened by youth radicalization, particularly in educational environments. This study examines how critical thinking, inclusion, and active student involvement in Student-Centered Learning (SCL) can prevent radicalization in Islamic junior schools in Indonesia and Bangladesh. Through problem-solving and open communication, SCL exposes students to a variety of viewpoints and fosters critical thinking, which lessens their vulnerability to extremist beliefs.
Design/methods/approach – Employing qualitative techniques, such as teacher and student interviews, the research delves into the distinct implementation obstacles of SCL in each nation.
Findings – Results show that although SCL promotes respect for one another and critical thinking, its efficacy is limited by a systemic dependence on conventional techniques, a lack of resources, and inadequate teacher preparation. 
Research implications/limitations – The study emphasizes how important it is to have resources, support at the policy level, and professional development in order to adequately utilize SCL as a deterrent to radicalization. For educational policymakers and groups seeking to establish safe and welcoming learning environments in Bangladesh, Indonesia, and other comparable countries, these findings provide insightful information.
Ústavní zakotvení účinků práva Evropské unie v České republice

The contemporary debate on the effects of European law within the Czech legal system after the accession of the Czech Republic to the European Union questions the European clause of the Czech Constitution (Act no. 395/2001 Coll.) as a reliable point of departure for decision-making by the Czech judicial authorities. The ECJ doctrines of direct applicability and supremacy of EC law (duly to apply the EC law provisions and the duty to disapply the respective national law provisions) cannot be comprehended through the nationally based monistic approach to the effects of international treaties, as the national constitutional autonomy has been constrained by the implicit waiver of some parts of sovereignty through the Accession Treaty. The picture of practice of the existing Member States shows that the friendly application of EC law results from living constitutions even under restraint constitutional texts and without any explicit instruction for national judicial authorities at the national level. Therefore, the Czech European clause must be interpreted in a way compatible with principles of uniform application of the EC law derived from the EC Treaty by the ECJ. Such an interpretation cannot be regarded as unconstitutional. There is couple of political and legal remedies which should be used to avoid a conflict of the Czech constitutional law provisions with the EC law.
Charta základních práv Evropské unie
Authors: Šturma Pavel
Published: February 2025

The European Union Charter of Fundamental Rights is a document which has attracted, in spite of its rather short history, a great interest. It is a first comprehensive bill of fundamental (human) rights adopted by the EU. On one hand, the Charter distinguishes itself from other international instruments by its original structure and large scope of declared rights, dividing into six chapters according to the underlying protected values. The Charter includes both “classic” human rights and freedoms, taken over from the European Convention of Human Rights, many “new” rights of economic and social nature, as well as the EU citizenship’s rights. On the other hand, the Charter still lacks a legally binding force. This should change by way of incorporation into the draft treaty establishing the constitution for Europe. Nevertheless, the Charter has some indirect effects already today. The present analysis has therefore focused rather on the scope of the Charter and the extent of the guaranteed rights. The main restriction arises from the fact that the Charter’s provisions are addressed to the institutions and bodies of the Union with due regard for the principle of subsidiarity, and to the Member States only when they are implementing Union law. From the point of view of the scope of beneficiaries, the Charter makes difference between the rights of everyone (all persons), the rights of EU citizens and the rights of nationals of the third states. The Charter also provides for the scope ratione materiae of fundamental rights to the effect that nothing in the Charter shall be construed as limiting or derogating from the human rights and fundamental freedoms recognized by the EU law, international agreements (in particular the European Convention of Human Rights) and by the constitutions of the Member States. A diverse nature of rights in the Charter has as a consequence that some of them Jack direct effect and may be applied only within the framework of EC/EU legislation or national law. Implementation of the Charter can be done first of all by judicial way, which would need a solution of concurrent relations between the ECJ and the ECHR. Another way of control consists of monitoring the policy of the Member States, ensured by reports of the EU Network of Independent Experts in Fundamental Rights.

Currently at EU level, there discussions on suitability of unification some common legal rules of private law, mainly the law of contracts take place. Present sectoral approach of European legislation to the normative regulation of interna) market shows alerting deficiencies. Generally, trouble is not the porous structure itself. More worse result is ununified terminology, comminuted method of regulation, diverse quality and strictness of harmonization of member states of EU and also following heterogenous application of law. These consequences become evident in the interna) market. Cross-border trade within EU is still rare event. Businessmen probably apprehend to make a step on the unknown soil. They can not be sure which new duties and consequent costs would it l market. These troubles will increase mainly due to the growth of e-business and prospect entrance of new member states. At the EU level, the discussion on unification, which would solve problems mentioned above has been started slowly. Does the unification stands derogation of national civil codes and in case of Great Britain the derogation of huge sector of their common law? Unification has been refused and on the other hand embraced by many politicians and experts for either material or symbolic reasons. In 2003, European Commission assumed an Action pian in which outlined its concept of prospect development: Detailed analyse of legal orders of member states will be elaborated. Subsequently on its ground, a set of optional rules of private law will be prepared. Road to exclusive code will depend on success of this facultative legal framework.

Authors: Zeman Pavel
Published: February 2025

The article about Eurojust starts by mentioning the Presidency Conclusions in Tampere in 1999 and tries to put the history of Eurojust in a wider frame of the mutual legal assistance in criminal matters such as the treaties of Council of Europe and the Schengen system. The author describes the role, structure, powers and future of Eurojust not only on the basis of the legal instruments (the Council decision setting up Eurojust) but also on the basis of the practical experience. You can get the knowledge about the status of the national member, the work of the college, the role of the administrative director but also about the newly created legal department. By describing the powers of Eurojust the author mentions not only the Council decision setting up Eurojust but also other European documents which have the impact on the work and competences of Eurojust. Special place have the competence the on field of the fight against terrorism and the competence in the execution of the European arrest warrant. Speaking about the position and powers of the national member, there is a special part explaining the powers and possibilities of the Czech national member and also describing the Czech approach to the implementation of the Council decision. The article describes not only the current stage of Eurojust but mentions also some weak points of the current situation, possibility how to improve the functioning of Eurojust and some ideas for the future of the organisation.
The digital-intercultural-transdisciplinary nexus: Online international exchanges for transdisciplinary education
Authors: Tsao Jack , Alhadad Sakinah , Heinrichs Danielle , Abdul Hameed Suraiya , McLay Katherine
Published: February 2025

Transdisciplinary problem-solving using digital technologies can further the internationalisation agenda within higher education through an inquiry-based collaborative online international exchange that is transformative and contributes real-world knowledge. Our study focused on a 12-week fully online programme bringing together undergraduates and postgraduates from a Hong Kong university and two Australian universities to research the well-being of university students. Drawing on Pierre Bourdieu’s concepts of field and habitus, we analysed the implementation and effectiveness of digital technologies in influencing the students’ experiences of sharing, learning and collaboration practices. The findings highlight the significance of online learning spaces for intercultural sharing beyond disciplinary spaces and generate tensions and ambiguities that provoke students to critically reflect on comparative cultural and social perspectives. This space for educational exploration and possibilities can move students beyond the taken-for-granted and expose them to diverse viewpoints and ways of thinking conducive to transdisciplinary learning and research.
 
Implications for practice or policy:

Higher education institutions and educators can leverage purposefully designed digital technologies and structured online exchange programmes to create equitable international and transdisciplinary collaboration and inquiry spaces.
Educators can use multimodal digital technologies, such as collaborative platforms (e.g., Miro, Canva) and creative methods (e.g., digital storytelling, body mapping) for students to engage with ambiguity, negotiate cross-cultural tensions and build critical self-awareness in collaborative settings.
Higher education institution policies can support students as co-creators of knowledge.
Role of complex energy and momentum in open cavity resonances
Authors: Kang DongJun , Jeon Eun Su , Yoo SeokJae
Published: February 2025

Complex power, also known as alternating current (AC) power, is a well-established concept in an electric circuit composed of resistive and reactive elements. On the other hand, the role of complex power in optics has been elusive. In this work, we reveal that the complex energy and momentum determine the resonance frequency and the decay rate of open cavity resonance, the so-called quasinormal modes (QNMs), respectively. We also demonstrate the role of the complex energy and momentum in typical open cavities analytically and numerically: the Fabry–Perot cavity, the surface plasmon polaritons (SPPs), the plasmonic nanorod, the nanosphere, and the dielectric supercavity.
Statistical separation of mixtures in the problem of reconstructing the coefficients of an Itô stochastic process-type model of the interplanetary magnetic flux density: ℓ
2-distance minimization vs likelihood maximization
Authors: Karpov Kirill , Korolev Victor , Sukhareva Natalia
Published: February 2025

Two approaches to the problem of statistical separation of finite mixtures of probability distributions are discussed. The first of them consists in finding maximum likelihood estimates of the parameters of the mixture by the EM-algorithm, whereas the second approach consists in finding the values of the parameters that deliver minimum to the distance between the theoretical and empirical distribution functions. It is demonstrated that the second approach is preferable at least in the problem of statistical reconstruction of the coefficients of an Itô stochastic process that requires dynamic separation of finite normal mixtures in the moving window mode. For this problem, the performance of the numerical procedures is critical. A combination of numerical procedures is described that provides (almost) the same value of the likelihood function for the second approach that is attained by the EM-algorithm, but ensures multiple decrease of the ℓ
2-distance between the theoretical mixture and the empirical distribution function while demonstrating better performance. A kind of ‘metric’ regularization of the problem of likelihood maximization is proposed. The proposed techniques are illustrated by adjusting the Itô process model to the time series of the interplanetary magnetic field (magnetic flux density) registered by the Global Geospace Science (GGS) Wind apparatus (the spacecraft placed in the Lagrange point between the Earth and the Sun).
On a semi-explicit fourth-order vector compact scheme for the acoustic wave equation
Authors: Zlotnik Alexander , Lomonosov Timofey
Published: February 2025

We deal with an initial-boundary value problem for the multidimensional acoustic wave equation, with the variable speed of sound. For a three-level semi-explicit in time higher-order vector compact scheme, we prove conditional stability and derive 4th-order error bound in the enlarged energy norm. It exploits additional sought functions which approximate 2nd-order non-mixed spatial derivatives of the exact solution. At the first time level, a similar two-level in time scheme is applied, without using derivatives of the data in the problem. No iterations are required to implement the scheme. We also present results of various 3D numerical experiments. They demonstrate a very high accuracy of the scheme, for smooth data, and its advantages in the error behavior over the classical explicit 2nd-order scheme, for nonsmooth data. An example of the wave in a layered medium (with a discontinuous speed of sound) initiated by the Ricker-type wavelet source function is also included.
Reducing tinnitus via inhibitory influence of the sensorimotor system on auditory cortical activity
Authors: Sabados Anne , Kim Cora , Rampp Stefan , Bergherr Elisabeth , Buchfelder Michael , Schnell Oliver , Müller-Voggel Nadia
Published: February 2025

Tinnitus is the subjective perception of a sound in absence of corresponding external acoustic stimuli. Research highlights the influence of the sensorimotor system on tinnitus perception. Associated neuronal processes, however, are insufficiently understood and it remains unclear how and at which hierarchical level the sensorimotor system interacts with the tinnitus-processing auditory system. We therefore asked 23 patients suffering from chronic tinnitus (11 males) to perform specific exercises, aimed at relaxing or tensing the jaw area, which temporarily modulated tinnitus perception. Associated neuronal processes were assessed using Magnetencephalography. Results show that chronic tinnitus patients experienced their tinnitus as weaker and less annoying after completion of relaxing compared to tensing exercises. Furthermore, (1) sensorimotor alpha power and alpha-band connectivity directed from the somatosensory to the auditory cortex increased, and (2) gamma power in the auditory cortex, reduced, which (3) related to reduced tinnitus annoyance perception on a trial-by-trial basis in the relaxed state. No effects were revealed for 23 control participants without tinnitus (6 males) performing the same experiment. We conclude that the increase in directed alpha-band connectivity from somatosensory to auditory cortex is most likely reflecting the transmission of inhibition from somatosensory to auditory cortex during relaxation, where concurrently tinnitus-related gamma power reduces. We suggest that revealed neuronal processes are transferable to other tinnitus modulating systems beyond the sensorimotor one that are e.g. involved in attentional or emotional tinnitus modulation and provide deeper mechanistic insights into how and through which channels phantom sound perception might be modulated on a neuronal level.

Significance StatementTinnitus describes the perception of auditory phantom sounds. Research suggests that the sensorimotor system impacts on tinnitus perception, associated neuronal mechanisms, however, have remained unclear. Here, chronic tinnitus patients performed exercises with the jaw temporarily reducing (versus increasing) tinnitus perception. Tinnitus reduction was accompanied by an increase of alpha-band connectivity directed from the somatosensory to the auditory cortex and gamma power reduction in the auditory cortex. We suggest that the increase in alpha-band connectivity, when tinnitus is reduced, reflects the transmission of inhibition from somatosensory to auditory cortex, where, in parallel, probably tinnitus-related, gamma power reduces. The findings have important implications both for the understanding of phantom sound perception and, more generally, of top-down modulation in healthy and impaired cognition.
Increased Modulation of Low-frequency Cardiac Rhythms on Resting-state Left Insula Alpha Oscillations in Major Depressive Disorder: Evidence from A Magnetoencephalography Study
Authors: Liao Qian , Dai Zhongpeng , Pei Cong , Zhang Han , Hua Lingling , Zhou Hongliang , Sheng Junling , Yao Zhijian , Lu Qing
Published: February 2025

A growing body of evidence suggests that the link between the cardiac autonomic nervous system (ANS) and the central nervous system (CNS) is crucial to the onset and development of major depressive disorder (MDD), affecting perception, cognition, and emotional processing. The bottom-up heart-brain communication pathway plays a significant role in this process. Previous studies have shown that slow-frequency oscillations of peripheral signals (e.g., respiration, stomach) can influence faster neural activities in the CNS via phase-amplitude coupling (PAC). However, the understanding of heart-brain coupling remains limited. Additionally, while MDD patients exhibit altered brain activity patterns, little is known about how heart rate variability (HRV) affects brain oscillations. Therefore, we used PAC to investigate heart-brain coupling and its association with depression. We recorded MEG and ECG data from 55 MDD patients (35 females) and 52 healthy subjects (28 females) at rest and evaluated heart-brain PAC at a broad-band level. The results showed that the low-frequency component of HRV (HRV-LF) significantly modulated MEG alpha power (10 Hz) in humans. Compared to the healthy group, the MDD group exhibited more extensive heart-brain coupling cortical networks, including the pars triangularis. LF-alpha coupling was observed in the bilateral insula in both groups. Notably, results revealed a significantly increased sympathetic-dominated HRV-LF modulation effect on left insula alpha oscillations, along with increased depressive severity. These findings suggest that MDD patients may attempt to regulate their internal state through enhanced heart-brain modulation, striving to restore normal physiological and psychological balance.

Significance StatementThe afferent pathway from the heart plays a pivotal role in conveying information to the brain. This process involves the transmission of signals related to the physiological state of the heart. Our understanding of this pathway and its association with major depressive disorders (MDD) remains limited. In this study, the low-frequency component of heart rate variability (HRV-LF) was found to modulate neural activity during rest, revealing a bottom-up information transmission mechanism between the cardiac ANS and the CNS. Alterations in the LF-alpha coupling pattern were observed in patients with MDD, suggesting this as a potential neurobiological mechanism behind their altered interoception, which might affect the perception and emotional processing.

Effectiveness of Water Bamboo as Phytoremediation Agent BOD and COD Leachate
Authors: Ihtiar Ade , Ulfah Maria , Kaswinarni Fibria
Published: February 2025

Leachate is  a liquid with an unpleasant odor and dark color that generally contains high organic and inorganic matter. High levels of organic and inorganic matter in leachate will potentially cause environmental pollution if not treated properly. One of the efforts that can be made to overcome these problems is with phytoremediation techniques. This study aims to determine the effectiveness of water bamboo (Equisetum hymale) as a phytoremediation agent  of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) leachate of Jatibarang landfill. This study used experimental research with a one-factorial Complete Randomized Design (RAL) design with three treatments (P0 without water bamboo, P1 750 gr water bamboo, and P2 1000 gr water bamboo). Based on the results of research shows that water bamboo plants can reduce BOD and COD levels. The decrease in leachate BOD levels was caused by the phytoremediation process by water bamboo during the study, where the organic matter content in leachate would be degraded by microorganisms. Meanwhile, COD levels decreased due to the chemical oxidation reaction process and phytoremediation process that runs side by side. The effectiveness of reducing BOD levels most optimally occurred in treatment P2 on day 7 of treatment, which was 28.42%; while the percentage of effectiveness of reducing COD levels most optimally occurred in treatment P2 on day 7 of treatment, which was 39.14%

Published: February 2025

The mangrove area in Tritih Cilacap, Central Java is decreasing due to illegal logging. This affects the distribution pattern of gastropods. This study aims to determine the distribution pattern of gastropods and provide information related to physical chemical factors that play a role in gastropod distribution patterns. This study was conducted at five sampling points. Five sampling points from the sea to the land. The sampling method used for gastropods was collection from 1x1 m plots. Gastropods in the plot were collected by hand on the top of the sediment and in the sediment were taken 10 cm deep using a corer with 3 repetitions for each station. Environmental parameters measured were: temperature, salinity, organic matter content, pH, and substrate type. The distribution of gastropods in Tritih Cilacap mangrove forest has a clustering and random pattern. There were 11 species of gastropods found from 7 families. Gastropod species that have clustered distribution patterns are: Ceritidhea alata, Telescopium telescopium, Neritina violacea, Neritina zigzag, Chicoreus capucinus, and Assimenia brevicula. Gastropod species that have random distribution patterns are: Ceritidhea quadrata, Neritina lineata, Cassidulla aurisfelis, Cassidulla nucleus, and Littoraria carinifera. The results of BIOENV analysis showed that the most influential environmental factors on gastropod density were water temperature, salinity, organic matter content and sand substrate.

Authors: Vallejo Romo Lucila del Carmen , Sevillano Monterroso Lorena Paola
Published: February 2025

La mayoría de los accidentes de trabajo ocurren como consecuencia de la falta de implementación de acciones preventivas que garanticen un ambiente de trabajo seguro. Al investigar los accidentes, es muy común pasar por alto la opinión de los trabajadores, motivo por el cual la solución se aborda únicamente desde la perspectiva de la empresa. Al incorporar la percepción de los trabajadores, se aporta un nuevo enfoque sobre la prevención de accidentes para optimizar la gestión de riesgos e incorporar nuevas formas de practicar la prevención. El propósito de este estudio fue identificar la relación entre la percepción de los trabajadores sobre los accidentes y la gestión de riesgos en una empresa de construcción. Para tal fin, se utilizó un enfoque cuantitativo no experimental y se emplearon encuestas para recolectar información precisa. El resultado de la investigación comprobó la relación directa entre la percepción de los accidentes por parte de los trabajadores de construcción y la gestión de riesgos de la empresa.

Authors: Arias Arce Vladimir Alejandro , Lovera Dávila Daniel Florencio , Molina Pereyra Ismael , Sánchez Rojas Tito Libio
Published: February 2025

The generation of cyanide-containing tailings is increasing, so the search for methodologies and microorganisms to counteract the negative action to the detriment of the environment is incessant. The present study was carried out with strains of Pseudomonas pseudoalcaligenes isolated from effluents of the gold ore cyanidation process. First, tolerance tests were performed in solutions with 250 ppm sodium cyanide at different pH values, using an initial population of 4.00E+07 CFU/mL and agitated for a period of 54 hours; degradation up to 39.2% free cyanide (CN-) was observed at a pH of 9.8. Then, in the CN- degradation for 144 hours, in media consisting of cyanidation process effluent solution at pH 10.5, with an initial bacterial population of 9.94E+08 CFU/mL and at concentrations of 80 to 700 ppm of CN-, reductions of 55.89 to 84.79 % of cyanide were obtained, expressed with the equations: y80 = -0.2393x + 73.05 and y700 = -3.6439x + 617.98, respectively. It was determined that the degradation of cyanide is directly related to the cyanide content in the solution; that is, the higher the cyanide concentration, the higher the abatement

Con el corazón desgarrado de dolor: la fotografía postmortem de subadultos durante las primeras décadas del siglo xx en el Perú
Authors: Estrada Moreno Flavio Antonio , Barraza Mendoza Martín
Published: February 2025

Since its invention, photography has allowed us to build a visual memory of the vital events of our existence and among them the death of a loved one as one of the most dramatic memories that allows us to remember the family member and in turn reminds us of our own inevitable destination. During the 19th and 20th centuries, a practice known as postmortem photography was developed, which was brought from Europe to America, where it developed with its own nuances. In its beginnings, photography was reserved for the most privileged social classes, while the less affluent social classes allocated their resources to preserve the first and only image of the deceased person, which is why this practice had enormous social and psychological importance. This article shows four postmortem portraits of subadult individuals whose data is found in the first two decades of the 20th century in Peru.

Published: February 2025

Background and aim: This study aimed to investigate the effect of paracetamol added as an adjuvant to intravenous regional anesthesia (IVRA) with lidocaine and prilocaine on patient satisfaction in patients applying for hand and forearm surgery.

Materials and methods: This study was approved by the Ethical Committee of KTU Medical Faculty. After obtaining written informed consent 46 patients between the ages of 18-65, ASA 1-2 physical status undergoing hand and forearm surgery were included in this study.

Patients were divided into 2 groups: Group Control (n=23) and Group Paracetamol (n=23). Group C was administered intravenous regional anesthesia (IVRA) with 1.5 mg/kg 1% of lidocaine and 1.5 mg/kg 1% of prilocaine. Group P was administered IVRA with the same local anesthetics and 1 mg/kg paracetamol. The study solutions were completed to 40 ml with saline. Mann-Whitney U test is used for numeric parameters without normal distribution and the student’s t test is used for numeric parameters with normal distribution. Q square was used for ordinal parameters. A p value <0.05 is regarded as statistically significant.

Demographic data, onset recovery of motor and sensorial block, durations of tourniquet and operation, VAS values, analgesic requirements, and patient satisfaction were recorded.

Results: There was no significant difference between the groups in terms of demographics, onset and recovery of motor and sensory block times, duration of operation, duration of tourniquet, VAS values analgesic requirements (p>0.05).

Patient satisfaction was higher in Group P when compared with Group C (p<0.01).

Conclusion: We conclude that the addition of 1 mg/kg paracetamol into the mixture of lidocaine and prilocaine in IVRA may improve patient satisfaction.

Apart from disability and injury and other diseases there are communicable diseases (CDs) and non-communicable diseases (NCDs) that cause mortalities. While the occurrence of CDs is slowly increasing, the occurrence of NCDs is increasing very fast. Globally, one of the major health threats under NCDs is cancer, which causes millions of deaths every year. There are many risk factors for cancer. Broadly, they are classified into three groups: behavioral risks, environmental risks, and metabolic risks. Behavioral risks include dietary risk, tobacco consumption, high drug and alcohol use, etc. Environmental risks refer to risks related to air pollution, unsafe water and sanitation, occupational risks, etc., while metabolic risks are those risks caused by high blood pressure, high plasma glucose, high LDL cholesterol, etc. In India also, both cancer cases and cancer-related deaths are increasing fast. But public facilities available for cancer screening and treatment are few and far between. Hence people opt for private hospitals, where service is good but cost is very high, and so out-of-pocket expenditure (OOPE) is very high. Most of the patients affected by cancer are men, aged between 50 and 70 and belonging to a middle- or low-income group. These views are supported by the primary data collected from Kanyakumari district. Of the surveyed patients, 56.67% are men and 40% (56.67% are men, 40% in the age group 50-70 years), and 76.67% of cancer patients belong to either a low- or middle-income group. The OOPE is about 66%. A few suggestions are given to make people feel relieved from the hazards of cancer. However, under the prevailing situations, the prevention and control of cancer is a challenging task for the government of India.

In the field of Geographic Information Systems (GIS), privacy and surveillance have emerged as critical ethical concerns, reflecting the growing tension between technological advancements and the protection of individual rights. This paper presents a review of the literature that investigates the ethical challenges associated with these issues, tracing their evolution and present significance. Drawing from scholarly discourse, we analyse how the capabilities of GIS have raised complex ethical dilemmas related to unauthorized data access, the construction of digital identities, and the increasing risk of pervasive surveillance. Our review reveals that while GIS offers considerable societal benefits, its unchecked potential for surveillance and infringement of privacy demands stronger ethical standards, regulatory frameworks and public awareness. We highlight the need for GIS professionals to adopt proactive measures, such as enhanced data security and informed consent protocols, to mitigate these risks. Furthermore, the study calls for ongoing scholarly inquiry into the ethical stewardship of GIS, emphasizing the importance of balancing innovation with the protection of individual freedoms. This research contributes to the broader dialogue on GIS ethics, advocating for responsible practices that prioritize privacy and limit the scope of surveillance, ultimately safeguarding personal autonomy in the digital age.
Modyular na Pagtuturo at Akademik Performans ng mga Mag-Aaral sa Filipino 10, Pampublikong Paaralan, Distrito ng Catigbian, Bohol
Authors: Pongase Diane
Published: February 2025

Ang pag-aaral na ito ay may pangunahing layunin na suriin ang antas ng kahusayan ng modyular na pagtuturo batay sa persepsyon ng mga mag-aaral sa Filipino 10 at sukatin ang kanilang akademikong performans sa asignaturang ito sa Distrito ng Catigbian, Bohol, Taong Panuruan 2021–2022. Gamit ang Transactional Distance Theory (1997) bilang batayan, sinuri ang kahusayan ng modyular na pagtuturo sa apat na dimensyon: Nilalaman ng Module, Gabay sa Pagtuturo, Gabay sa Pagkatuto, at Pagtataya at Feedback. Ang pag-aaral ay binuo ng 192 respondente na napili sa pamamagitan ng random sampling. Natuklasan sa pamamagitan ng weighted mean na may positibong pananaw ang mga mag-aaral sa kahusayan ng modyular na pagtuturo, na may grand mean na 4.26, na itinuturing na “napakataas.” Gayunpaman, mababa ang akademikong performans ng mga mag-aaral sa Filipino 10, na may average iskor na 35.03 sa dalawang pagtataya, na nagpapahiwatig ng ilang hamon sa aktwal na pagkatuto. Ang mga resulta ay nagpakita ng makabuluhang ugnayan sa pagitan ng edad at akademikong performans, samantalang walang epekto ang kasarian sa akademikong resulta. Walang makabuluhang pagkakaiba sa persepsyon at akademik performans sa pagitan ng mga lalake at babae, at magkatulad ang kanilang resulta sa una at ikalawang pagtataya. Ang mga natuklasan ay nagpapakita ng pangangailangan para sa mga guro na magpatupad ng mas masusing gabay at alternatibong istratehiya sa pagtuturo upang matiyak ang epektibong paggamit ng mga module. Iminumungkahi rin ng pag-aaral ang pagrepaso sa mga nilalaman ng module at pagpapabuti ng feedback at interbensyon sa pagkatuto, na maaaring magdulot ng pagtaas sa akademikong performans ng mga mag-aaral sa Filipino 10.
Mga Salik na Nakaaapekto sa Antas ng Komprehensyon at Akademik Performans sa mga Mag-Aaral ng Filipino 10 Unang Distrito ng Consolacion, Lunsod ng Cebu: Kaparaanang Pampagpabuti
Authors: Alesna-Tuñacao Jennifer
Published: February 2025

Ang pag-aaral na ito ay sumasaliksik sa masalimuot na ugnayan sa pagitan ng edad, kasarian, antas ng pang-unawa, at pagganap sa akademiko ng mga mag-aaral. Sa pamamagitan ng pagsusuri ng data mula sa 230 mga kalahok, natuklasan ang mahahalagang kaalaman. Habang ang edad ay hindi nagpapakita ng tuwirang ugnayan sa antas ng pang-unawa, ang kasarian ay lumutang bilang isang mahalagang salik, kung saan ang mga babae ay nagpapakita ng kakaibang mas mataas na antas ng pang-unawa. Gayunpaman, walang makabuluhang ugnayan ang edad o kasarian sa pagganap sa akademiko. Isang nakababahalang takbo ang lumutang kung saan ang karamihan sa mga mag-aaral ay hindi nakakamit ang inaasahang antas ng pagganap sa akademiko, na nagpapahiwatig ng agarang pangangailangan para sa pagpapabuti. Natukoy ang iba’t ibang mga salik na nakakaapekto sa pang-unawa at pagganap, tulad ng tradisyonal na mga mapagkukunan ng edukasyon at online na mga tool, kung saan ang online na mga tool ay lalong nagpapahirap sa parehong aspeto. Ang mga alalahanin na ito ay salamin ng pananaw ng mga guro, na nagpapahayag ng katulad na mga negatibong epekto. Sa kabuuan, binibigyang-diin ng pag-aaral ang mahalagang papel ng pang-unawa sa pag-abot sa tagumpay sa akademiko at nag-aalok ng serye ng mga rekomendasyon. Kabilang dito ang pagpapatibay ng kasanayan sa pagbasa sa pamamagitan ng mga espesyalisadong estratehiya sa pagtuturo, pag-address sa pangangailangan para sa pagpapabuti sa pagganap sa akademiko, pagsusulong ng balanseng paggamit ng mga kagamitang pang-edukasyon, at pagsasaayos sa ugnayan sa pagitan ng antas ng pang-unawa at pagganap sa akademiko. Ang pagpapatupad ng mga rekomendasyon na ito ay nagpapangakong magpatibay sa larangan ng edukasyon at magbigay ng mahalagang suporta sa mga mag-aaral sa kanilang mga pagpupunyagi sa akademiko.

Published: February 2025

This study aims to explore the relevance of the fundamental principles of Islamic communication in the context of digital communication in the modern era, focusing on the principles of shidiq (truthfulness), amanah (trustworthiness), tabligh (communication), and fathanah (wisdom). The study also discusses the role of Islamic communication management in digital dakwah, along with the challenges and opportunities that arise in spreading Islamic messages through digital platforms. The research method used is a literature review with a qualitative approach, where the researcher examines various relevant sources on Islamic communication principles and their application in modern communication, particularly in the context of social media and information technology. The results show that the principles of Islamic communication play a significant role in maintaining the quality of communication in the digital era. Truthfulness, trustworthiness, and wisdom in communication are crucial in minimizing misinformation, hate speech, and social polarization that often emerge in the online world. Moreover, digital dakwah offers an opportunity to spread Islamic messages in a more inclusive and dynamic manner, but it still requires prudent management to ensure the messages conveyed are accurate and responsible. This study suggests the importance of integrating modern communication theories with Islamic principles to create ethical, harmonious, and constructive communication in the digital world.
Fatores aceleradores, mantenedores e sancionadores da inflação
Authors: BRESSER-PEREIRA LUIZ CARLOS , NAKANO YOSHIAKI
Published: February 2025

RESUMO Para entender a inflação ou estagflação no capitalismo oligopolista atual, é necessário distinguir os fatores aceleradores, mantenedores e sancionadores da inflação. Quatro são os fatores aceleradores: mudanças nas margens de lucro, mudanças nos salários reais acima (ou abaixo) da produtividade, mudanças na taxa de câmbio real e nos custos das importações. Os fatores básicos de manutenção são a indexação formal e informal da economia e o mark-up de preços. Dada uma inflação autônoma, isto é, independente da demanda sustentada ou do pleno emprego, o fator sancionador fundamental da inflação será a oferta de moeda.
