Authors: Ishak Muhammad Nur
Published: August 2024

This study aims to analyze the People's Housing Savings (Tapera) policy from the perspective of Islamic economics, with a focus on social welfare and distribution justice. Islamic economics puts forward the principles of social welfare and distributive justice, which emphasizes the fulfillment of basic needs, spiritual and moral well-being, and the fair and equitable distribution of wealth. In this context, this study evaluates how Tapera's policies can be integrated with Islamic economic principles to achieve these goals. The research method used is a qualitative method with a descriptive-analytical approach. The data was collected through literature studies, analysis of policy documents, and in-depth interviews with Islamic economics and housing experts. The analysis was conducted to identify the suitability of Tapera's policies with Islamic economic principles and assess their impact on social welfare and wealth distribution. The results of the study show that Tapera's policies are in line with several Islamic economic principles, such as zakat, alms, and qard al-hasan, which aim to reduce economic disparities and promote social welfare. Tapera has succeeded in providing better access to housing for low- and middle-income people, improving their quality of life. However, the study also found some challenges, including limitations in fair distribution mechanisms and the need for greater transparency and accountability in fund management. Tapera's policy has great potential to support social welfare and distribution justice in accordance with Islamic economic principles. However, further efforts are needed to optimize the implementation of this policy to be more effective and efficient. This research provides practical recommendations for policymakers to strengthen aspects that are in line with Islamic values and overcome existing obstacles, with the ultimate goal of creating a more just and prosperous society

Authors: Rafi Siregar Muhammad
Published: August 2024

This research aims to explore the role of sharia economics in turning recession challenges into opportunities in Indonesia. The research method used is a mixed approach that combines quantitative and qualitative methods. The exploration phase involves an in-depth literature study of the principles of sharia economics, analysis of successful cases from other countries, and interviews with stakeholders in Indonesia. The analysis phase includes the collection of macroeconomic and microeconomic data, as well as qualitative data through in-depth interviews and focused group discussions. The results of the study show that the sharia economy makes a significant contribution to Indonesia's economic growth in recession conditions. The implementation of sharia economic principles, such as the prohibition of riba and the practice of gharar, has the potential to increase economic stability by encouraging investment oriented towards the real and sustainable economy. The use of zakat and waqf in the sharia economy has also proven to be effective in reducing socio-economic inequality and increasing a fairer distribution of income. The conclusion of this study emphasizes the importance of strengthening Islamic financial infrastructure, increasing Islamic financial literacy in the community, and strengthening cooperation between the public and private sectors in supporting Islamic economic growth. Challenges that need to be addressed include a clearer regulatory framework and strong policy support to expand the penetration of the sharia economy in key sectors. With the right implementation of recommendations, the sharia economy can play an important role in building sustainable economic stability and prosperity in Indonesia, as well as make a significant contribution to effectively overcoming the economic recession

Published: August 2024

This study investigated the relationship between telecommunications development, trade openness and economic growth in South Africa. It determined explicitly if telecommunications development and trade openness directly impact economic growth or whether telecommunications strengthen or weaken the link between trade openness and economic growth using the ARDL bounds test methodology. The findings reveal that both telecommunications development indicators and trade openness significantly and positively impact South Africa’s GDP in the short and long terms. The study also found that control variables like internet usage and gross fixed capital formation significantly and positively influence GDP. Conversely, inflation was found to consistently affect GDP negatively and significantly. The findings from the ARDL cointegration analysis affirm a long-run economic relationship between the independent variables and GDP. The study also established that telecommunications development slightly distorts trade in the foreign trade-GDP nexus in South Africa. Despite this, the negative interaction effect is not substantial enough to overshadow the positive impact of trade openness on economic growth. From a policy perspective, the study recommends that South African policymakers prioritise enhancing local goods’ competitiveness in global markets and reducing trade barriers. It also advocates for improving the accessibility and affordability of telecommunications technologies to foster economic development.

Published: August 2024

This study aims to elucidate the impact of marketing investment dimensions (MTS, MTOE, ROMI) on profitability indicators (ROA, ROE, GPM, OPM) and sustainable growth indicators (SGR, ARG) for service companies. The study population consisted of 135 service companies listed on the Amman Stock Exchange. A purposive sample of 55 companies was selected from this population. Financial reports and statements from 2018–2022 for these companies were analyzed to achieve the study objectives, employing appropriate statistical methods like multiple regression to test hypotheses. Previous literature shows conflicting results regarding the relationship between marketing investment dimensions and profitability/sustainable growth. Some studies found positive impacts, while others did not. This study contributes to this debate by providing statistical evidence. The results show that higher MTS, MTOE, and ROMI have a positive impact on SGR, OPM and ROA but a negative impact on GPM, ARG, and ROE. This underscores that marketing investments should be viewed in conjunction with overall operating expenses. Companies that control other expenses and increase the marketing investment proportion of total operating expenses may achieve better financial performance. Marketing investment metrics can serve as useful diagnostics and measures of effectiveness for improving marketing profitability, financial performance, and growth. In summary, this study statistically demonstrates the nuanced impacts of marketing investments on service company profitability and sustainable growth indicators. The results emphasize analyzing marketing spends in context of broader expenses and overall company financial health.

Published: August 2024

Since the implementation of repair processes by composite patch bonding, this process has consistently demonstrated high performance across various industrial sectors, especially in the fields of aeronautics, aerospace and civil engineering. Consequently, there are situations in which the riveting process becomes the sole solution, particularly when the structure is subjected to severe mechanical or thermo-mechanical stresses, since adhesives have low mechanical strength after aging. Each method has its own set of advantages and disadvantages. The current trend is to combine these two processes to minimise their drawbacks as much as possible. The objective of this work is to present an experimental study on the repair of an aluminium plate AL2024-T3 with a central circular notch using a patch of different nature (metal or composite), under tensile loading conditions. The repair composite considered is a carbon/epoxide. The results of the tensile tests showed that the repair by the combination of the two processes improves the mechanical strength of the damaged structure. A comparison of the results of the experimental curves obtained on riveted, bonded and hybrid assemblies has been taken into consideration.

Authors: See Xin Ya , Chang Yu-Cheng , Peng Chun-Yu , Wang Shih-Syuan , Chi Kuan-Yu , Chiang Cho-Hung , Chiang Cho-Han
Published: August 2024

Introduction

Current guidelines recommend limiting the rate of correction in patients with severe hyponatremia to avoid severe neurologic complications such as osmotic demyelination syndrome (ODS). However, published data have been conflicting. We aimed to evaluate the association between rapid sodium correction and ODS in patients with severe hyponatremia.

Materials and methods

We searched PubMed, Embase, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials from inception to November 2023. The primary outcome was ODS and the secondary outcomes were in-hospital mortality and length of hospital stay.

Results

We identified 7 cohort studies involving 6,032 adult patients with severe hyponatremia. Twenty-nine patients developed ODS, resulting in an incidence rate of 0.48%. Seventeen patients (61%) had a rapid correction of serum sodium in the first or any 24-hour period of admission. Compared with a limited rate of sodium correction, a rapid rate of sodium correction was associated with an increased risk of ODS (RR, 3.91 [95% CI, 1.17 to 13.04]; I2 = 44.47%; p = 0.03). However, a rapid rate of sodium correction reduced the risk of in-hospital mortality by approximately 50% (RR, 0.51 [95% CI, 0.39 to 0.66]; I2 = 0.11%; p < 0.001) and the length of stay by 1.3 days (Mean difference, −1.32 [95% CI, −2.54 to −0.10]; I2 = 71.47%; p = 0.03).

Conclusions

Rapid correction of serum sodium may increase the risk of ODS among patients hospitalized with severe hyponatremia. However, ODS may occur in patients regardless of the rate of serum sodium correction.

Problematising “World Class” public education policy in South Australia: Insights for education policy makers
Authors: Bills Andrew , Howard Nigel , Hattam Sarah
Published: August 2024

This policy-interested South Australian public education case study problematises how the Chief Executive (CE) and members of the Education Department’s Senior Executive Group (SEG) understood system and school improvement from 2018 to 2022. We applied Carol Bacchi’s, “What’s the Problem Represented to be?”(WPR) policy analysis framework to unearth the policy assumptions underlying the Department’s overarching policy ensemble called “World Class,” initiated across South Australia’s public primary and secondary schools. WPR reveals heightened centralised technologies of command and control directed at teacher and leader work to achieve McKinsey defined World Class status by 2028.

We find school improvement policy solutions were engineered through “managerially enforced complexity reduction” techniques within the paradigm of the Global Education Reform Movement (GERM). These techniques impacted policy prescriptions, performance management technologies, school improvement plans, curriculum materials for schools, and promoted NAPLAN as the ultimate measure of the good school, the good teacher, and the good principal. NAPLAN is the National Assessment Program—Literacy and Numeracy used in Australia and takes the form of an annual standardised assessment for students in Years 3, 5, 7 and 9.

Most concerningly, we find the policy logics of World Class worked to incentivise inequality across public schools through diminishing the purposes of public education and the professionalism of educators. We conclude arguing for the democratisation of existing departmental structures within iterative inquiry-based approaches to policy formation and practice to better attend to public education purposes.
How does adulteration of wax foundation affect phenoloxidase and lysozyme activities as selected parameters of immunity in Apis mellifera?

Published: August 2024

Introduction

The adulteration of wax foundation is, for many reasons, a growing problem of modern beekeeping not only in Europe but also around the world. Wax foundation contaminated with stearin addition leads to a brood die-off, while paraffin addition negatively affects the strength of combs. It is tenable that such adulterated wax foundation reduces bees’ immunity. The aim of the study was to determine the activities of two bee immune enzymes, lysozyme and phenoloxidase, in the haemolymph of worker bees which had emerged from combs with wax foundations contaminated with stearin or paraffin.

Material and Methods

Combs built with stearin- or paraffin-adulterated wax (both adulterants at concentrations of 10%, 30% or 50%) or pure wax (0% adulterated) foundations were placed in the colonies, one for each adulterant and percentage. The workers were marked upon emergence from these combs and those bees were introduced into one strong colony per adulterant and percentage. Phenoloxidase and lysozyme activities were determined in the haemolymph of 1-, 7- and 14-day-old workers.

Results

The higher the concentrations of stearin and paraffin in the wax foundation, the lower the phenoloxidase activities were. These activities increased with the bee age. In contrast, the trends in lysozymes were opposite. Paraffin seems to be less toxic than stearin.

Conclusion

Adulteration of wax foundation with even a small amount of stearin or paraffin has negative effects on the functioning of the bee.
A Novel Method to Obtain Reverse Bias I–V Curves for Single Cells Integrated in Photovoltaic Modules
Authors: Drif Mahmoud , Bouchelaghem Ahmed , Guemache Abderezak , Benhamadouche Djoubair Abdelouahab , Saigaa Djamel
Published: August 2024

Despite the existence of accurate mathematical models facilitating the analysis of photovoltaic (PV) sources’ behaviour under diverse conditions, including normal operation and situations involving mismatch phenomena such as partial shadowing and various faults (i.e., PV cells operating in forward bias and reverse bias quadrants), an important issue still persists. Crucial parameters essential for adjusting these models, particularly those related to reverse-biased characteristics such as breakdown voltage, are often absent in manufacturers’ datasheets. This omission presents a substantial challenge, as it restricts the ability to acquire comprehensive and accurate information required for a thorough analysis of devices in the second quadrant. To address this issue, our research introduces a novel method for measuring the reverse-biased I–V characteristics of individual PV cells within a module without having to dissociate them from the PV module encapsulants. The process involves measuring the forward-bias I–V curves of both the fully illuminated PV module and a partially shaded PV module with only one completely shaded cell. This can be achieved outdoors and by utilising commercially available I–V tracers. Thus, the reverse I–V curve can easily be derived from these forward bias I–V curves. Finally, the proposed method serves as a nondestructive technique for characterising solar cells in the second quadrant. This innovative approach offers a promising solution for assessing the performance and health of PV modules without causing damage and may result in significant cost savings.
Regional Export Strategies and Programs: Development Algorithm (the Example of the Tomsk Region)
Authors: Shpakova R. N. , Gorodetskiy D. I.
Published: August 2024

Introduction. The article analyzes the problems that arise in the development of regional export strategies and programs. The regional export strategy of the Tomsk region, a region with average export characteristics and, at the same time, which has recently encountered a complex of problems typical for a significant number of regions in export activities, has been selected as an object for analysis. The algorithm of strategy development is proposed. It is considered advisable to adopt a special methodological document containing optimal analytical procedures necessary for the development of export strategies and programs, as well as a mechanism for evaluating the effectiveness of their implementation.

Materials and methods. The research materials used the provisions of federal projects and regulations related to the support of export and investment activities, regional strategic planning documents of the Tomsk region, statistical data on export dynamics. The methodological basis of the study was the following general scientific methods: statistical, analysis, synthesis, method of interpretation of normative acts and others.

The results of the study. The study found that in the absence of methodological development of the main provisions defining the specialization of the regional export strategy, this document can only play the role of a formal duplication of the provisions of regional socio-economic development strategies.

First of all, within the framework of a special methodological recommendation document, it is

necessary to prescribe the analytical component of the development of an export strategy and regional programs adopted in accordance with it. In particular, there is a need for methodological foundations for conducting an export audit, which is provided for by the Regional Export Standard.

Discussion and conclusion. An algorithm of actions is proposed for the development of a regional export strategy and program, which allows structurally ordering a set of measures to support exports.

In addition, when developing export support measures, it is advisable to divide existing and potential exporters into groups regarding their readiness to expand export activities, followed by differentiation of support measures and effectiveness assessment in relation to each of the groups.

Published: August 2024

No Brasil, o dimensionamento de sistema hidráulicos prediais de água fria é realizado principalmente por meio da utilização do Método do Consumo Máximo Provável dos Pesos Relativos, entretanto, também há a possibilidade do dimensionamento com a aplicação de um coeficiente de vazão (K), obtido por meio de curvas de vazão x pressão. Desta forma, objetivou-se verificar a possibilidade de dimensionamento racional, pelo emprego de modelos de aparelhos sanitários distintos, em um sistema hidráulico predial de água fria de uma edificação multifamiliar utilizando o sofware EPANET 2.2. O estudo foi realizado para uma edificação multifamiliar de quatro pavimentos, sendo que cada um deles possui dois apartamentos com área de 45,66 m². A rede foi dimensionada por meio do método dos Pesos Relativos e por meio de tentativas utilizando o sofware EPANET 2.2, adotando curvas x pressão. Porteriormente foi realizada a comparação dos dois cenários. A partir disso, o cenário em que foi considerado todos os aparelhos sanitário, exceto a bacia sanitária com válvula de descarga, foi o que gerou maior interesse prático, além disso, foi notório que a presença da válvula de descarga na bacia sanitária impossibilitou um dimensionamento ótimizado, devido à sua alta vazão. Por fim, pôde-se notar o impacto do aumento da classe de vazão dos aparelhos sanitários no funcionamento hidráulico da rede, uma vez que os diâmetros também foram aumentados.

Published: August 2024

Novel drug delivery systems offer several advantages as compared to conventional systems. Drugs can be effectively delivered topically by being incorporated into gel, which will prevent first pass metabolism and increase local action for skin conditions. Hydrogels are 3D polymeric system structure of hydrophilic polymers. The main goals of hydrogels are to improve patient compatibility, and release medication at a controlled rate with maximum therapeutic effects. Bakuchi oil is obtained from the seeds of Psoralea corylifolia (family: Leguminosae), which has anti-inflammatory qualities. Research was conducted to investigate how to enhance anti-psoriatic activity by using herbal Bakuchi oil in the form of hydrogel. Carbopol 940 (carbomer) polymer, Transcutol-P as a permeation enhancer, and triethanolamine for pH adjustment were used to prepare hydrogel. The impact of formulation variables, such as concentration of polymer and permeation enhancer, on the formulation responses was assessed. Optimized formulation F8 demonstrated a maximum drug release of 85.36±0.33% in 1 hour. Viscosity and spreadability of formulation F8 were found to be 5089±0.70 cps and 11.45±1.47 gm.cm/sec respectively. The findings suggested that a successful herbal formulation containing Bakuchi oil can be developed with improved rheological properties and good permeation profile.

This plant from the Apocynaceae family has been investigated for a wide range of medicinal uses, including pain relief, antifungal effects, inflammation reduction, parasite expulsion, ulcer treatment, dysentery remedy, diabetes management, cancer therapy, fever reduction, and wound healing. These effects are due to the presence of multiple bioactive compounds found in different parts of the plant. This research focused on formulating a pharmaceutically stable herbal gel containing W. tinctoria extract by applying central composite design for optimization and evaluating its phytoconstituents, physical and chemical properties, and various quality control parameters including appearance, pH, spreadability, consistency, homogeneity, viscosity, drug release, stability, skin irritation study, and ex-vivo anti-candida activity in rats. The herbal gel formulation was found to have a pH value of 6.3±0.1, indicating that it is unlikely to cause skin irritation. The prepared herbal gel formulation's spreadability value was discovered to be 22.17±1.5 gm.cm/sec, signifying good spreadability. The extrudability of 89.53%, demonstrated excellent squeezability. During dermal irritation studies, no signs of redness or swelling were observed in the treated animals, indicating the formulation's safety. The major skin irritation index (irritability score) was zero, confirming its suitability for topical application. HPLC analysis confirmed the presence of indirubin, a bis-indole alkaloid, as a major active chemical constituent. The prepared herbal formulation also exhibited acceptable stability as per ICH guidelines. Furthermore, when the gel formulations were applied topically to rats infected with Candida albicans, notable wound healing activities were noted. These tests collectively ensured that the formulated gel was stable, safe, effective, and suitable for use.

Despite the traditional use of Cucurbita pepo seed to enhance milk production during lactation, its effect in non-lactating females remains scarce. The aim of this study was to investigate the effect of n-hexane (nHE), Dichloromethane (DCM) and Aqueous ethanol (Aq. Eth) extracts of C. pepo seed on serum prolactin levels of non-lactating female Wistar rats. A total of 44 non pregnant female rats weighing 190 g were randomly grouped into 11 groups of 4 rats, for treatment as follows: A (control): 0.5 mL 5% Tween 80 (vehicle); B (positive control): 10mg/kg Clomiphene Citrate, C, D & E: 142.86, 285.71, and 428.57 mg/kg of nHE; F, G & H: 142.86, 285.71, and 428.57 mg/kg of DCM; and I, J & K: 142.86, 285.71, and 428.57 mg/kg of Aq. Eth extracts of C. pepo seed. Vaginal cytology monitored the estrous cycle daily, and blood samples were obtained for serum prolactin at various oestrus cycle phases. There was no significant (P>0.05) variation in serum prolactin levels in rats treated with 142.86 mg/kg, 285.71 mg/kg, and 428.57 mg/kg of all three extracts of C. pepo during the Proestrus, estrus, and metestrus phases relative to the control. A significant (P<0.05) increase in serum prolactin levels was observed at the diestrus phase in rats treated with 142.86 mg/kg, 285.71 mg/kg, and 428.57 mg/kg of n-HE, 428.57 mg/kg of DCM and 142.86 mg/kg, 285.71 mg/kg of Aq. Eth extracts of C. pepo seed, relative to the positive control group. Rats treated with 142.86 mg/kg of Aq. Eth had a significant increase in serum prolactin in the diestrus phase, relative to the control. The findings of this study show that C. pepo seed extracts may exhibit a phase-specific effect within the estrous cycle of non-lactating female rats and as such may have potential applications in regulating prolactin levels.
A importância das fantasias inconscientes para a relação mãe-bebê: Klein e atualidade

O texto busca trazer uma comparação entre a teoria de Melanie Klein acerca da relevância das fantasias inconscientes, como a representação mental das pulsões do lactente, para o vínculo mãe-bebê e uma temática atual. Dessa maneira, em um primeiro momento, apresenta um resumo expandido sobre a obra de Klein, desde as contribuições freudianas para o surgimento do termo “fantasias inconscientes”. Em um segundo momento, por sua vez, explora textos dos últimos 15 anos, os quais abordam as angústias das mães, as expectativas quanto à gestação de seu bebê e quanto ao vínculo com ele. Conclui-se que o foco se expandiu para contextos delicados (como prematuridade, adoecimento, vulnerabilidade social, etc.) e foi apontado que a relação necessita da existência da criança no universo imaginário materno, sendo essencial que uma equipe multiprofissional auxilie a mãe na criação de um elo com seu filho. Por fim, acrescenta-se a noção de que as ansiedades do bebê não derivam exclusivamente de sua experiência, mas também podem ser herdadas, segundo a autora brasileira Trachtenberg, com um foco maior nas fantasias inconscientes geradas pelo psiquismo materno e como elas afetam o vínculo mãe-bebê.
