Authors: Salsabila Daffa Annisa , Purwidianti Wida , Handayani Erna , Kharismasyah Alfato Yusnar
Published: January 2025

Aims: The aim of this research is to determine the influence of VAIC and GCG on ROA in financing services sub-sector firms listed on IDX in 2019 – 2023. Intellectual Capital quantified by value added capital employed (VACA), value added human capital (VAHU), and value added structural capital (STVA). GCG in this case is proxied with the audit committee, board of directors and independent commissioners.
Study Design: Intellectual Capital and Good Corporate Governance are independent variables, while the dependent variable is financial performance.
Place and Duration of Study: Unbalanced panel data was used for this study from finance services sub-sector companies that met the sample criteria from 2019 to 2023.
Methodology: The sampling technique used was purposive sampling, so that 33 companies with 105 data were obtained. The analysis technique used is the classical assumption test and multiple regression analysis in SPSS 22.
Results: The findings of this study indicate that intellectual capital gauged by VACA and STVA positively affect ROA, while VAHU negatively affect ROA, VAHU has a negative impact on ROA if investment in human capital is not balanced with the resulting productivity. Management inefficiencies, competency mismatches, and high costs without direct results can reduce the contribution of human capital to profitability, thereby lowering ROA. The second finding revealed that Good Corporate Governance as gauged by the audit committee, board of directors and independent commissioners does not influence ROA. Optimization of human resources with the right skills and experience will improve operational efficiency, reduce wasteful spending, and ultimately contribute to better financial management.

Although sand mining provides short-term economic benefits, such as increased income for local communities, the long-term consequences can hinder sustainable economic growth. In addition, sand mining also causes environmental damage, such as erosion and damaged ecosystems.
The Belt and Road Initiative: China’s Vision for Global Connectivity and Soft Power Influence
Authors: Chiebuka Amaziroh Queendaline , Janet Oyedele Opeoluwa , Oluchi Odike Christabel
Published: January 2025

The Belt and Road Initiative (BRI), launched in 2013 by Chinese President Xi Jinping, represents a pivotal framework for global connectivity, encompassing infrastructure development, cultural exchange, and economic integration. Built on the historical Silk Road, the BRI consists of the "Silk Road Economic Belt" and the "Maritime Silk Road," spanning Asia, Africa, and Europe. Through investments in transport networks, energy grids, and maritime ports, the initiative seeks to establish a new model of international cooperation based on policy alignment, financial integration, and people-to-people exchange. While proponents view the BRI as a platform for mutual development, its implications extend beyond economic growth. The initiative is a cornerstone of China's soft power strategy, enhancing its influence by exporting its development model and reshaping global governance norms. Research underscores its impact on Africa, where infrastructure projects align with Agenda 2063, emphasizing industrial growth, trade enhancement, and regional connectivity. Despite these benefits, concerns about debt sustainability, geopolitical maneuvering, and governance challenges persist. Using qualitative methods, this paper evaluates the BRI's dual role as an economic tool and a soft power strategy. It examines the initiative's integration with Africa’s development goals, highlighting theoretical insights into international cooperation. The BRI’s success depends on fostering equitable partnerships and addressing geopolitical complexities. This study underscores the initiative's transformative potential in reshaping global economic dynamics while reflecting on its broader implications for governance and sustainability.

Published: January 2025

The management of viruses in cowpea is a challenging task and the use of nanoparticles (NPs) presents a promising opportunity for novel antiviral strategies. This study evaluates the viricidal activity of silicon dioxide nanoparticles (SiO₂NPs) against cowpea aphid-borne mosaic virus (CABMV) under controlled conditions. Silicon dioxide nanopowder formulation was used in this study. The virus, molecularly characterized as CABMV, was maintained through mechanical transmission. Pre- and post-inoculation of virus followed by NP foliar spray at different concentrations were done in local lesion host, Chenopodium amaranticolor, and propagative host, cowpea. The studies using various concentrations of SiO₂NPs on C. amaranticolor and cowpea revealed that pre- or post-inoculation of the virus combined with a foliar spray of SiO₂NPs at 1000 ppm is an effective treatment, exhibiting no local lesions compared to 34 local lesions in the viral control. In cowpea, among the various concentrations tested, foliar application of SiO₂NPs at 1000 ppm before CABMV inoculation reduced the vulnerability index (VI) to zero, followed by SiO₂NPs at 500 ppm, which achieved a VI of 2.77compared to viral control (VI – 94). The efficacy of NP treatment was further validated by assessing the viral titre using DAS-ELISA, with treated plants showing a sevenfold reduction in viral titre compared to the control. A significant reduction in the number of local lesions in C. amaranticolor and the vulnerability index in cowpea demonstrated the pronounced impact of SiO₂NPs on viral particles. Simultaneous inoculation of the virus and NPs showed reduced, diffused local lesions on leaves treated with viral sap-containing NPs, compared to a higher number of intact lesions in the control. This reduction is likely due to the disintegration of viral particles by NP treatment, leading to decreased disease severity. These findings further emphasize the potential of SiO₂ NPs in mitigating the severity of cowpea aphid-borne mosaic disease.

This research analyzed and compared the DeFocus curve of the most widely used premium intraocular lenses (IOLs) in Brazil (At Lisa, Zeiss; Finevision, BVI; Gemetric, Hoya; Panoptix, Alcon and Synergy, Johnson), evaluating their variability, clarity between trifocal designs and effectiveness, as well as side effects and patient satisfaction. The systematic review included 46 articles (2010-2024) available in scientific databases. The analyses revealed significant differences in the DeFocus curves, with emphasis on PanOptix® and FineVision, which showed uniformity and stability at multiple distances. Hybrid lenses, such as Vivinex Gemetric, combined good visual performance and lower incidence of aberrations. While the optimized redistribution of light in trifocal lenses declared superiority in visual acuity at all distances, and the most reported side effects were halos and glare, especially in the initial postoperative period, with a tendency to decrease due to neurovisual adaptation. Furthermore, general satisfaction was high, with reduced dependence on glasses and improved quality of life of patients. It is therefore concluded that IOLs Premium trifocals are highly effective in visual correction and present significant clinical benefits for each situation sought in Brazilian clinical practice, despite some adverse effects.
Dynamics of Communicable and Non-Communicable Health Shocks in the Campo Ma’an National Park: Implications on Natural Resources Dependent Livelihoods
Authors: Ndikebeng Kometa Raoul , Kimengsi Jude Ndzifon , Mvo Wanie Clarkson
Published: January 2025

Issues of health shocks continue to gain traction in the global scientific discourse, with established evidence on its severe impacts on livelihoods and well-being especially in sub-Saharan Africa. However, the relative absence of a comparative analysis on the effects of communicable and non-communicable diseases on natural resources dependent communities still beg for scientific attention in the context of the Campo Ma’an National Park.  This study sought to examine the determinants and dynamics of health shocks, and their implications on natural resource-dependent communities of the Campo Ma’an National Park.  Data was collected through interviews with key informants, experts, and a survey of 200 households. The results indicate that health shock dynamics are primarily influenced by socio-demographic factors, followed by ecological and economic variables. Communicable diseases such as malaria and COVID-19, and non-communicable diseases such as cancer and hypertension, reveal distinct risk patterns. These diseases have affected more than 70% of the population over the past five years. These shocks exacerbate poverty, hunger, and economic stagnation, leading to death and job loss. Furthermore, health shocks have shaped livelihood strategies leading to diversification, intensification and business as usual scenarios. The logistic regression disclosed gender, education, age, income, occupation, proximity to park, as the variables that significantly predict livelihood dynamics during health shocks. The findings inform the vulnerability dimension of the sustainable livelihoods framework and underscores the need for policy interventions to develop resilient livelihood.
Das Gesetz zur Versorgung mit Cannabis zu medizinischen und medizinisch-wissenschaftlichen Zwecken (Medizinal- Cannabisgesetz – MedCanG)
Authors: Ratzel Rudolf
Published: January 2025

Von der breiten Öffentlichkeit weniger beachtet als die unter bestimmten Rahmenbedingungen begrenzte Freigabe von Cannabis durch das KCanG, hat der Gesetzgeber mit dem MedCanG einen im Vergleich zur vorherigen Rechtslage vereinfachten Zugang zu medizinischem Cannabis geschaffen. Wahrgenommene Verordnungspraxis und ein genauer Blick ins Gesetz werfen die Frage auf, ob der Gesetzgeber nicht etwas über das Ziel der medizinisch indizierten und ärztlich verantworteten Versorgung mit medizinischem Cannabis hinausschießt. und letztlich zum 1.4.2024 in Kraft getreten ist, ist das MedCanG3 quasi in seinem Windschatten weitgehend unbeachtet ebenfalls zum 1.4.2024 in Kraft getreten. Dies ist umso bemerkenswerter als es faktisch und in Teilen wohl auch rechtlich zu einer weitgehenden Freigabe der Verordnung und damit des Vertriebs von Cannabis zu medizinischen Zwecken jedenfalls dann führt, wenn die Verordnung außerhalb der GKV, also auf Privatrezept (auch als E-Rezept) erfolgt. Außer Nabilon fallen diese Cannabisprodukte nicht mehr unter das BtMG. Eine Genehmigungspflicht der Krankenkasse, wie sie § 31 Abs. 6 SGBV mit hohen Hürden vorschreibt, existiert außerhalb der GKV nicht.4 Ob die Verordnung indiziert ist, entscheidet alleine der die Verordnung ausstellende Arzt (§ 3 Abs. 1 MedCanG). Eine besondere Qualifikation benötigt der verordnende Arzt nicht. Er muss jedenfalls nach dem MedCanG keine Praxis betreiben oder in einer medizinischen Einrichtung tätig sein, weil unterstellt werden kann, dass ein Großteil dieser Verordnungen ohnehin nicht zur Erstattung eingereicht werden. Ob der Arzt aus berufsrechtlichen Gründen in eigener Niederlassung oder in einer medizinischen Einrichtung tätig sein muss, steht auf einem anderen Blatt.5 Über den Botendienst einer Apotheke oder eine Versandapotheke kann man sich „sein“ Cannabis bequem nach Hause schicken lassen.6 Die Hürden sind niedrig und einschlägige Vertriebswege werden im Netz aggressiv beworben.7 Die nachfolgenden Ausführungen verstehen sich als Ergänzung zu Jacoby, Die Abgabe von medizinischem Cannabis im System der gesetzlichen Krankenversicherung, GesR 2024, 681 ff.

Complejidad y contradicciones de las relaciones entre los grupos islamistas: el caso de Siria
Authors: Ramírez Díaz Naomí
Published: July 2023

Con una realidad cambiante en Oriente Medio, el régimen sirio se encuentra en una difícil coyuntura. De caer el régimen y viendo la tendencia en otros países, el islam político podría jugar un papel clave en la formación del nuevo gobierno, lo que podría reconfigurar las otrora complejas relaciones entre los grupos islamistas de la zona. Este artículo profundiza en las contradicciones de estas relaciones partiendo de las negociaciones entre el régimen sirio y los Hermanos Musulmanes con vistas a garantizar la vuelta de estos a Siria y las mediaciones que han llevado a cabo sus homólogos en otros países. Abstract In a changing context in the Middle East, the Syrian regime is in a difficult situation. Should the regime fall, and considering the trend of other Arab countries, political Islam will play a key role in the formation of the new government. This, in turn, could result in a redefinition of the formerly complex relationships between Islamist groups in the area. This article focuses on the contradictions inherent to these relationships through the study of the negotiations between the Syrian regime and the Muslim Brotherhood whose aim was the return of the latter to Syria, and the study of the mediation that their counterparts in other countries have carried out.

It has long been known that poetic and philosophical attitudes to the world are interrelated, although mutual opposition and repulsion are also common. The idea of the real complexity of the interaction of poetry and philosophy is contained in a variety of types of poetic and philosophical practice, as well as concepts reflecting them. No less interesting is the practical implementation of these relations in the life and work of modern Russian poets and philosophers. One of them is Vladimir Natanovich Porus. We are starting a new section of the journal with his poetry collection. We invite readers to speak out.
The Clarity and Validity of the Concept of Psychological Contract
Authors: Njenga Francis Ndirangu
Published: July 2023

Researchers have argued that the construct of psychological contract in its current form and application lacks clarity and validity. However the debate has stagnated but the research has continued being carried out without considering the diverging views on the subject. This article aims at bridging the gap on the operational definition of the construct, the content of the contract relevant for workplace and the influence on attitudes and behavior. This is articulated through knowledge blending of the theories of law, linguistic and social psychology. The foundation of the construct stems from the assumption that for two parties to draw maximum benefits from their relationship they have to develop commitment and cooperation. The process begins when the party processing the power and effect undertakes to satisfy the needs or interest of the referent other who in turn reciprocate with increased trust and loyalty. In a relationship the psychological contract is the feelings or beliefs held by one party that the other party has adopted to satisfy their need/desire/interest/goal. The content of psychological contract is based on workplace needs frame around Hertzberg two factor to correspond with the different types of equity sensitivity predispositions. This article seeks to theoretically present clarity to the construct of psychological contract in a coherent manner that joins together the current two schools of thought namely classical and reliance (two parties).

Authors: مرغم د. ليلى التهامي
Published: July 2023

Education is an important tool for States' development and progress economic, social and political impediments, in addition to promoting the concept of sustainable and inclusive development in various areas ", especially in this era of remarkable development in the educational process, which has produced significant progress in embracing the concepts of sustainability, until education became the deadly weapon in the face of underdevelopment, poverty and ignorance. Education is one of the key pillars of inclusive development in its economic, social and political dimensions which is a key to progress and urbanization for any State in view of its leading role in sustainable development, Since the eighteenth century, economists - Adam Smith, Marx, Marshall and Maltus - have alerted the importance of investing in human capital through education and training But not until the 1950s and 1960s, Several applied studies have confirmed that economic development consists of two main components: The human component, which includes increasing human capacities by raising the level of education and raising the level of health; The material component, which includes increasing economic growth rates, is increasing per capita domestic product, and human capital theory emphasizes the important role that education plays as a key factor in the accumulation of human capital, achieving sustainable development and reducing poverty rates. Based on the importance of the impact of education in general on sustainable development as determined by economic theories and international experiences, this study seeks to analyse the impact of education on human development in Libya. The main problem of this study is to answer the following key question: What is the impact of education on human development in Libya during the period 1990-2019? Theoretically, the study's importance is to illustrate the inability to achieve sustainable development. without human development, education is the main dimension of human development and sustainable development is a necessary requirement for all developed and developing countries, Education is also one of the most important forms of investment in human capital. In addition, the practical importance of this study is to examine the impact of education on Libya's human development. development policies that lead to inclusive development. Drawing on the use of the analytical curriculum to determine the relationship between education and human development at the theoretical level, and analysing this relationship statistically, to test the study's main hypothesis: a statistically significant relationship exists between education and human development in Libya during the study period.

In this paper, Norlund Nt- difference sequence spaces Nt(c0, p, ∆), Nt(c, p, ∆) and Nt(ℓ∞, p, ∆) contain the sequences whose Nt∆-transforms in c0, c and ℓ∞ are defined and the paranormed linear structures are developed on these spaces. It has been shown that the spaces Nt(c0, p, ∆), Nt(c, p, ∆) & Nt(ℓ∞, p, ∆) are linearly isomorphic and are of non-absolute type. Further, it is verified that Nt(c, p, ∆), Nt(c0, p, ∆)and Nt(l∞, p, ∆) of non-absolute form are isomorphic to Nt(c0, p), Nt(c, p) and Nt(ℓ∞, p), respectively. Topological properties such as the completeness and the isomorphism are also discussed. Some inclusion relations among these spaces are also verified. Finally, the α-, β- and γ- dual of these spaces are determined and constructed the Schauder-basis of Nt(c0, p, ∆) and Nt(c, p, ∆).

Assessment of bronchial obstruction in adolescents infected with human immunodeficiency virus
Authors: Ilias Hameurlaine , Houdouin Véronique , Bokov Plamen , Caseris Marion , Faye Albert
Published: July 2023

Introduction : In adults chronically infected with HIV, there
is an increased prevalence of impaired respiratory function, with a
greater occurrence of COPD ( Chronic obstructive pulmonary disease) than
in the uninfected population. In children, data from the literature show
a higher prevalence of atopy. Additionally, adolescents treated since
birth for HIV infection in utero often exhibit bronchial hyperreactivity
or peripheral bronchial obstruction, indicating chronic local
inflammation. This study aims to evaluate the value of early detection
of peripheral obstruction in HIV-infected adolescents, initiating early
treatment and preventing long-term respiratory function impairment in
adulthood. Methods : This prospective monocentric study
included patients aged 11 to 25. Participants underwent forced
oscillometry, conventional respiratory functional exploration, and
completed a respiratory quality of life questionnaire. The primary
endpoint was the parameter R5Hz Results : 21 teenagers were
included in our study. Regarding the primary endpoint, one patient out
of 13 (7.6%) showed an increase in R5Hz. Three (23%) exhibited
abnormal resistance exploration. Regardless, three patients met the
criteria for bronchial hyperreactivity. Concerning the questionnaire,
three patients, despite having no respiratory function impairment,
reported a decreased quality of life associated with breathing.
Conclusion : There is probably approximately 15% of children
infected with HIV at birth in France experiencing chronic lung
inflammation. More accurate detection through oscillometry would enable
precise identification of these children and offer them targeted
treatment. This approach could not only improve their quality of life
but also help preventing progressive decline in respiratory function and
the development of chronic bronchopathy in adulthood.

Study Of Productivity And Costs On The Implementation Method Of Foundation Work Using Precast Concrete Pile As A Substitute To The Use Of Wooden Pile Foundations In Low Rise Building (Housing)
Authors: Syahrudin Syahrudin , Safaruddin Nuh M. , S Soeryamassoeka B , Erwin Sutandar
Published: July 2023

The soil condition in Pontianak City is mostly soft soil and peat soil which causes the low bearing capacity of the soil. Various efforts have been made to increase the bearing capacity of the soil, such as the use of wooden pile (kayu cerucuk). With the limited availability of wooden pile, the use of precast piles is an alternative in increasing the bearing capacity of the soil on the foundations of buildings/housings in Pontianak City. The purpose of this study is to compare the productivity and costs of using a wooden pile foundation measuring 12/15 cm with a length of 9-12 M against the use of a square precast concrete pile foundation measuring 15x15 cm2 with a segment length of 3-4 M at a depth of 12-20 M and a size of 12-20 M. 20x20 cm2 with a segment length of 6 M at a depth of 12-18 M in low-rise buildings in Pontianak City. From the results of the study, it is known that the productivity and average cost of piling per M' in a 2-storey shophouse building with an alternative foundation using 12/15 cm cerucuk piles is 22.3 seconds/m' at a cost of Rp. 17,306.24, precast piles square 15 x 15 cm2 of 111.5 seconds/m' at a cost of Rp. 144,274,439 and precast square piles of 20 x 20 cm2 of 125.7 seconds/m' at a cost of Rp. 291,338,955. In a type 150 house building with an alternative foundation using 12/15 cm wooden piles of 18.05 seconds/m' at a cost of Rp. 17,185.58, precast square piles of 15 x 15 cm2 of 104.67 seconds/m at a cost of Rp. 143,890.04 and 20 x 20 cm2 square precast piles of 94.66 seconds/m' with a cost of Rp. 289,724.234. The cost of foundation work with alternative foundations using precast square piles of 15 x 15 cm2 is the most efficient both from the aspect of driving costs, overall costs and the cost of the unit load carried by the foundation

Objective: To study the clinical value of hepatitis B virus pregenomic RNA (HBV-pgRNA) detection in the treatment of hepatitis B. Methods: 60 patients with hepatitis B were included in the study. Serum HBV-pgRNA and HBV DNA levels in different phases of infection and during treatment were detected, and serum hepatitis B surface antigen (HbsAg) titer was detected by chemiluminescent immunoassay. DNA was extracted from liver biopsy tissue, and covalently closed circular DNA was detected to predict the therapeutic value in patients. Results: At the initial stage of treatment, the level of HBV-pgRNA in phase I, II, III, and IV showed a gradual decrease. Comparing the levels of HBV-pgRNA before and after treatment, we found that the level of HBV-pgRNA was significantly lower after treatment (P < 0.05). Among the indicators for predicting HBsAg seroconversion, the accuracy of HBV-pgRNA level was 85.0% (51/60). Conclusion: The clinical value of HBV-pgRNA detection in the treatment of hepatitis B is high.

Güneş panellerinin çıkış gerilimi, ışınım, sıcaklık, gölgelenme gibi farklı birçok faktöre bağlı olarak değişmektedir. Bu gibi faktörlerin çevresel şartlara bağlı olarak değişkenlik göstermesi nedeniyle PV panel testleri sırasında aynı çevresel şartların tekrar oluşturulması mümkün değildir. Ancak, PV panel emülatörleri, belirli bir zaman dilimi için çevresel verileri kullanarak o dönemdeki şartları taklit edebilmektedir. Gerçekleştirilen çalışmada, kısmi gölgelenme etkilerini modelleyebilen, model tabanlı bir PV paneli emülatörü tasarlanmıştır. Emülatör, her biri 20 hücreden oluşan ve atlama diyotları ile bağlanmış hücre gruplarını temsil eden üç adet DC/DC dönüştürücüye, 250 W çıkış gücüne ve 32-bit mikro-kontrol kartına sahiptir. Emülatörün yazılımı Matlab Simulink modelleri kullanılarak gerçekleştirilmiştir. Tasarlanan PV emülatörü, dört farklı gölgelenme senaryosuyla test edilmiştir. Elde edilen deneysel sonuçlar, MATLAB/Simulink ortamında alınan simülasyon sonuçlarıyla karşılaştırılmıştır. Elde edilen sonuçlar, deneysel ve simülasyon sonuçlarının oldukça yakın olduğunu göstermiştir. Yüksek performansı ile emülatör, herhangi bir alanda, çatıda veya cephede kurulacak PV sistemlerinin teknolojik ve ekonomik fizibilite analizini kolaylaştırır.

Because potato is a crop, demanding moisture supply conditions its yield depends on the ability to use the moisture accumulated during the calendar year by the root system during the growing season. However, the intensification of technological methods of potato production using powerful energy-saturated mobile agricultural units leads to a significant deterioration of the soil condition due to over compaction of the arable and subsoil horizons which hinders the normal mode of movement of intrasoil moisture and the development of the root system of plants. Reducing the number of passes of agricultural units across the field is possible when using combined units that perform several technological processes in one pass. For this purpose, a multifunctional combined potato-planting unit has been developed at St. Petersburg State Agrarian University that combines preplant tillage, planting potato seeds, the use of agrochemicals, pesticides and water-retaining agents, as well as deep loosening of interrow spacing and the formation of full-volume ridges. The conducted studies have shown the effectiveness of the use of such a combined unit by providing favorable soil conditions for the growth and development of plants.
