Gender Roles and Labor Dynamics in Household Composting Practices in Ndeiya, Kiambu County, Kenya
Authors: Njeri Rhodah , Mainah Muthoni , Okemwa Pacificah , Guettou Nadia
Published: January 2025

Composting is an agroecological practice that is commonly adopted by small-scale farmers in different food systems. It not only aided in reduced reliance on chemical inputs, in improving soil health but also in waste management within households. The division of labor and task allocation for household members in the composting process was however often accompanied by traditional gender norms. This resulted in unequal distribution of roles and imbalanced agricultural productivity as a ripple effect. This study examined the gender roles and labor dynamics in household composting practices among small-scale farmers who adopted compost manure in Ndeiya, Kiambu County, Kenya. This research used key informant interviews, focus group discussions, and questionnaires to identify: specific gender-related responsibilities in composting activities; challenges associated with these roles; and implications for gender equity and agricultural productivity. The findings of this study indicated that men were more involved in physically demanding tasks like turning large compost heaps and pushing wheelbarrows carrying compost manure to the farm. In the same vein, women were overburdened with tasks that demanded much of their time, such as gathering raw materials and daily compost management. The cumulative workload on women often led to reduced efficiency in the composting process and, by extension, impacted soil quality and crop yield negatively. These roles also not only reflected but also reinforced gender inequities in household and agricultural labor. This highlighted the need for equitable labor distribution at the household level.
Floating Cities: Xi Xi, Magritte, and the Insouciance of Allegory
Authors: Kochhar-Lindgren Gray
Published: January 2025

`Floating Cities: Xi Xi, Magritte, and the Insouciance of Allegory’ examines the ekphrastic relation of text and image in relation to the operations of analogy, the proportions of which have cracked, and allegory as an insouciant genre. Xi Xi’s short-story `Marvels of a Floating City’ is clearly linked to a reflection on Hong Kong’s hand-over from London to Beijing in 1997, but it also passes through that fixed date to ask how such an image-text might operate along different registers as we pass from Aristotle toward Benjamin and Deleuze. As Magritte rightfully insists, painting (like writing) is thinking and ekphrastic allegory opens up not only mourning for the passing of all things, but also an enigmatic joy that such a fractured passaging occurs at all, especially in those marvelous moments when cities are hovering as if suspended between the sea and the sky.

Efficiency plays a vital role in boosting agricultural productivity and ensuring sustainable food security. This study examines the technical, economic, and allocative efficiencies of maize-rice farmers in Southwest Nigeria, with a focus on differences across small, medium, and large-scale farming operations. The research utilized stochastic frontier analysis to assess efficiency levels and identify factors influencing productivity. Primary data were collected through structured questionnaires and focus group discussions (FGDs), involving 100 farmers selected via a multistage sampling technique. The findings revealed notable disparities in efficiency based on farm scale. Small-scale farmers exhibited the lowest technical and allocative efficiencies, primarily due to constraints such as limited access to inputs, credit, and extension services. Medium-scale farmers displayed moderate efficiency, while large-scale farmers achieved the highest efficiency levels, benefiting from economies of scale and access to advanced resources. Significant determinants of efficiency included farm size, education level, farming experience, and credit availability. The study underscores the importance of targeted strategies to improve efficiency across all scales. Key recommendations include enhancing access to credit and extension services, fostering cooperative formations, and encouraging the adoption of modern agricultural technologies. Implementing these measures can address efficiency gaps, boost productivity, and support sustainable agricultural development and food security in Nigeria.

The presence of Sufism in the midst of this global society is not only to provide responses and answers, not only question religious problems, but also about social, political and economic conditions of mankind. Sufism is an Islamic oasis that has a mandate in delivering necessary of human spirituality to the perfect stage. Sufism study is an Islamic study born from the womb of Sufism treasures in depth. Sufis have always rested on the dualism of truth between innate and inward, between historical and trans-historical sociology. Spiritual experimentation is not merely an individualistic idealistic experimentation, but also a social-idealistic experiment driven by a real sociological situation according civilization of the times. Then, to maximize the results of good and correct Sufism studies, it should use all existing methodologies inseparably. This is typical as a multidisciplinary approach. Use one of methodology without the other will reduce the formulation of Sufism which actually built on the spiritual experience of each individual original Sufi figure, the struggle of faith and their passion when struggling with the social reality faced and the recognition of the central text of Islam, namely Qur'an and hadith as normative foundation. Thus a brief review of discussion Sufism which provides an image complexity of approaches and instruments in reading it, with various aspects and scopes.

Ökaryotik hücrelerin sitoplazmasında yapısal proteinlerden oluşan hücre iskeleti bulunmaktadır. Hücre iskeleti ağı hücrelere daha ileri bir organizasyon sağlamaktadır. Hücreler, hücre
iskeleti sayesinde yapısal özellikler kazanır ve çevre hücreler ile etkileşime girebilir. Ayrıca hücre iskeleti, hücre içi organizasyonda, hücre hareketinde, organellerin hücre içi taşınmasında,
büyüme ve farklılaşma gibi pek çok hücresel süreçte görev almaktadır. Hücre iskeleti, hücre
bölünmesi, yara iyileşmesi ve kasılma gibi hücre hareketlerinde şekil değiştiren ve sürekli yeniden düzenlenen dinamik bir yapıya sahiptir. Hücre iskeletinin yapısı üç tip protein filamentinden
oluşur. Bu proteinler büyüklüklerine göre sırasıyla aktin filamentler, ara filamentler ve mikrotübüllerdir. Filament proteinlerin yapısına ayrıca çeşitli yardımcı proteinler katılır ve böylece
hücre iskeleti, hücre zarı ile organeller arasında ve hücre dışı matriks ve çevre hücreler ile
bağlantılar kurabilmektedir. Hücre içinde en çok bulunan hücre iskeleti proteini aktindir ve bu
proteinler mikroflamentleri meydana getirir. Mikrofilamentler hücrelere mekanik destek sağlar, hücre göçünde, hücrenin şeklinin belirlenmesinde ve korunmasında önemli rol alır. Mikrofilamentlerin motor proteini olan miyozin, çeşitli hücre tiplerinde kasılmadan sorumludur. Ara
filamentler protein tipleri oldukça çeşitlilik gösterir ve hücrede çeşitli görevlere sahiptir. Ara
filamentler hücre hareketine katılmaz, bunun yerine hücrelere mekanik güç sağlar. Ara filamentler ayrıca hücre içi sinyal iletiminde görev alır. Mikrotübüller, hücre iskeleti yapıları arasında en büyük çapa sahiptir. Mikrotübüllerin temel proteini globüler bir protein olan tübülindir ve
dinamik bir yapıya sahiptir. Mikrotübüller, hücre şeklinin belirlenmesi, hücre içi hareket, mitoz
kromozomlarının ayrılması gibi çeşitli hücre hareketlerinde görev almaktadır. Mikrotübüllerin
motor proteinleri olan kinezin ve dinein, hücre içi harekette görev almaktadır.

Bir organizmada, kendini yenileyebilen ve farklı hücre tiplerine dönüşebilen hücrelere kök hücre adı verilir. Kök hücreler farklılaşma kapasitelerine göre; totipotent, pluripotent, multipotent,
oligopotent ve unipotent olarak sınıflandırılır. Totipotent hücreler, tüm hücre tiplerine dönüşebilme kapasitesine sahiptir ve buna örnek olarak zigot verilebilir. Pluripotent hücreler, birçok
hücre tipine farklılaşabilirler ve blastokist aşamasında bulunan embriyonal kök hücreler bu
kategoriye girer. Multipotent hücreler, belirli hücre soylarına dönüşebilirler; örneğin, hematopoetik ve mezenkimal kök hücreler. Oligopotent hücreler, birkaç hücre tipine; unipotent hücreler
ise sadece tek bir hücre tipine farklılaşabilir.
Kök hücreler, köken aldığı hücre türüne göre de; embriyonal, fetal ve yetişkin kök hücreler ile
uyarılmış pluripotent kök hücreler olarak sınıflandırılır. Embriyonal kök hücreler pluripotent
olup, neredeyse tüm hücre tiplerine farklılaşabilirler, ancak etik kaygılar nedeniyle kullanımları
kısıtlıdır. Yetişkin kök hücreler, belirli doku veya organlarda bulunur ve hasar durumunda bu
dokuları yenilerler. Bu hücreler multipotenttir; hematopoetik, mezenkimal ve fetal kök hücreler
bu gruptandır. Yetişkin kök hücrelerin epigenetik olarak yeniden programlanmasıyla uyarılmış
pluripotent kök hücreler elde edilebilir.

Impact of regulatory changes on strategic treasury operations in a post-COVID-19 world
Authors: Olayinka Abiola-Adams  , Chima Azubuike  , Aumbur Kwaghter Sule  , Richard Okon
Published: January 2025

The COVID-19 pandemic has reshaped the global economic landscape, leading to significant regulatory changes that have had profound effects on strategic treasury operations. As organizations strive to adapt to the post-pandemic world, regulatory shifts aimed at enhancing financial stability, liquidity, and risk management have become central to treasury functions. This review explores how these evolving regulations impact multinational corporations (MNCs) by influencing cash flow management, capital allocation, and compliance requirements. Key regulatory updates include stricter liquidity coverage ratios (LCR), net stable funding ratios (NSFR), and enhanced stress-testing protocols, driven by global regulatory bodies like the Basel Committee and the Financial Stability Board (FSB). Additionally, new taxation policies, changes in cross-border regulations, and intensified scrutiny on digital payments and data privacy have compelled treasuries to reassess their strategies. The adoption of technologies such as AI, blockchain, and RegTech solutions has become critical in helping organizations navigate these changes efficiently, enabling real-time compliance, automated reporting, and enhanced risk management. This highlights the impact of these regulatory shifts on liquidity management, requiring treasurers to optimize cash reserves, streamline cash pooling, and adjust funding strategies. Furthermore, compliance with emerging cybersecurity laws and digital frameworks has become essential to safeguard financial data in an increasingly digitalized environment. Through case studies of leading firms, this review illustrates best practices in adapting treasury operations to the evolving regulatory landscape. Ultimately, the review concludes that a proactive approach to regulatory compliance, combined with the strategic use of technology, is essential for treasurers to optimize financial performance and maintain resilience in a rapidly changing post-COVID-19 world. Organizations that effectively integrate these strategies are better positioned to achieve long-term stability and growth amid ongoing economic uncertainties

Islamic finance, based on Sharia principles that prohibit interest (riba), excessive uncertainty (Gharar), and unethical investments, offers an alternative approach to asset and liability management (ALM) that has gained increasing attention in the global financial system. This review explores the impact of Islamic finance on global ALM practices, focusing on how its unique principles shape financial strategies, risk management, and liquidity structures. In contrast to conventional finance, which relies heavily on interest-bearing instruments, Islamic finance emphasizes asset-backed financing, profit-sharing, and risk-sharing mechanisms.  The review discusses how Islamic financial institutions manage their assets and liabilities using Sharia-compliant products such as Murabaha (cost-plus financing), Mudarabah (profit-sharing), Musharakah (joint venture), and Sukuk (Islamic bonds). These products align with the principles of risk-sharing and ethical investment, leading to distinct ALM strategies that emphasize the importance of tangible assets and real economic activity. Unlike conventional derivatives that are often used for hedging, Islamic finance promotes alternative risk management techniques such as Tawarruq (commodity-based hedging) and Wa’ad (unilateral promises), which avoid speculation and excessive uncertainty. The review also examines how Islamic finance contributes to diversification in global ALM practices, especially in markets with significant Islamic investor bases, such as the Middle East and Southeast Asia. The growing adoption of Islamic financial instruments by conventional financial institutions further demonstrates the integration of Islamic principles into mainstream ALM practices.  Islamic finance has a transformative effect on global ALM practices by providing ethical, asset-backed alternatives that promote stability, transparency, and sustainability. Its integration into the global financial system not only expands the range of financial products available but also introduces a more inclusive, risk-sharing approach to managing assets and liabilities.

Authors: Santos Luiz Ricardo dos , Sanches Fellipe de Oliveira
Published: January 2025

A Lei Maria da Penha, promulgada no Brasil em 2006, representa um marco significativo na luta contra a violência doméstica. Ela foi criada para proteger mulheres vítimas de agressão física, psicológica, sexual, patrimonial e moral dentro do ambiente doméstico. No entanto, os desafios para inibir esses casos persistem. Um dos principais obstáculos é a cultura arraigada de machismo, que minimiza ou justifica a violência contra as mulheres. Além disso, a falta de estrutura adequada nos sistemas de justiça e de segurança pública muitas vezes resulta na impunidade dos agressores, desestimulando as vítimas a denunciarem os abusos. O estudo tem como objetivo analisar a Lei Maria da Penha e os desafios para mitigar os casos de violência doméstica. A metodologia utilizada se trata de uma revisão bibliográfica. Conclui-se que apesar dos avanços proporcionados pela Lei Maria da Penha, ainda há um longo caminho a percorrer para garantir a eficácia na prevenção e combate à violência doméstica. É crucial investir em políticas públicas que promovam a educação para a igualdade de gênero desde cedo, bem como fortalecer os mecanismos de apoio e proteção às vítimas, incluindo o aprimoramento das redes de acolhimento e o acesso facilitado à justiça.
