The Intersection Between Child Marriage And Climate Change: An Example Of Malawi, Musu Bakoto Sawo Jul 2025

The Intersection Between Child Marriage And Climate Change: An Example Of Malawi, Musu Bakoto Sawo

Journal of African Policy Studies

Child marriage affects 39,000 girls daily, totaling 650 million women married before age eighteen globally. While driven by poverty, tradition, and limited education, climate change is emerging as a significant new factor, particularly in developing nations such as Malawi, where 42% of girls marry before age eighteen. An estimated 1.5 million girls in Malawi are at risk due to climate-exacerbated food insecurity and displacement. This paper, using feminist theories of intersectionality, postcolonial feminism, and feminist political ecology, examines the complex link between climate change and child marriage in Malawi. It critiques existing international, regional, and domestic policies, highlighting their inadequacy …


African Feminist Theories And The Gendered Dimensions Of Climate Change In Africa, Manase Kudzai Chiweshe Jul 2025

African Feminist Theories And The Gendered Dimensions Of Climate Change In Africa, Manase Kudzai Chiweshe

Journal of African Policy Studies

This paper analyzes how African feminist theories can provide nuanced insights into the gendered dimensions of climate change across the continent. African feminist theories provide essential insights into the everyday lived experiences of women within African spaces, allowing for a contextual analysis of the impacts of climate change. There has also been a growing recognition of the need to identify the gender-differentiated impacts of climate change. The main argument is not only that climate change will be experienced by men and women differently but also that the impacts will hurt women more severely. Yet this theorization must employ theoretical lenses …


Technology And The Sustainable Implementation Of The African Continental Free Trade Area (Afcfta) Through Women’S Integration, Philip Ademola Olayoku Jul 2025

Technology And The Sustainable Implementation Of The African Continental Free Trade Area (Afcfta) Through Women’S Integration, Philip Ademola Olayoku

Journal of African Policy Studies

The desire for economic prosperity on the African continent led to the African Continental Free Trade Area (AfCFTA), in line with the vision of the Organisation of African Unity (OAU), when it proposed the creation of an African Economic Community (AEC) by 2028. However, sustainable economic development will remain a mirage without inclusivity where no one is left behind, in line with the African Union’s Agenda 2063. This study explores the challenge of restricting women to economic margins in trade agreements under the AfCFTA and how this would undermine its implementation. It subsequently contends that women are integral to Africa’s …


Broadening The Scope Of The "Justiciability" Debate To Include The Right To Development: An Analysis Of The African Human Rights Monitoring Bodies, Serges Djoyou Kamga Jul 2025

Broadening The Scope Of The "Justiciability" Debate To Include The Right To Development: An Analysis Of The African Human Rights Monitoring Bodies, Serges Djoyou Kamga

Journal of African Policy Studies

The right to development (RTD) is the most controversial human right of our time. Opponents argue that it is not justiciable. Besides the adoption of the Draft Covenant on the RTD, the right is binding in the African human rights system. It is on this backdrop that the article shows the justiciability of this right through its juridification and application in domestic courts. It also examines the role of African human rights monitoring bodies in broadening the scope of the “justiciability” debate to include the RTD. This article examines the African Commission and Court’s pronouncements on the RTD and unveils …


Editor's Remarks, Julius A. Amin Jul 2025

Editor's Remarks, Julius A. Amin

Journal of African Policy Studies

Roughly two years ago, the University of Dayton Human Rights Center hosted a very important conference titled “Decolonization and Development for Africa and People of African Descent.” I attended this event and participated in several sessions of the conference. The topics and discussions were enlightening, and they stimulated much conversation about decolonization and development in relation to the social practice of human rights.

Participants at the conference came from both sides of the Atlantic, and those I spoke with agreed that the conference encouraged them to consider the topic of human rights with a new perspective. Within African studies, human …


Reclaiming Power: Decolonization And Development For Africa And People Of African Descent, Satang Nabaneh Jul 2025

Reclaiming Power: Decolonization And Development For Africa And People Of African Descent, Satang Nabaneh

Journal of African Policy Studies

The journey to this special issue has been a long and significant one for me, as an African deeply invested in the multifaceted realities of global Africa. Africa embodies the global. Its people, culture, and histories transcend borders, reflecting a deeply interconnected world. To speak of global Africa is to reject essentialist notions of African identity, recognizing that to be African is to be unbounded by space, place, or fixed definitions. This special issue, “Reclaiming Power: Decolonization and Development for Africa and People of African Descent,” was born out of the convergence of the 2023 Social Practice of Human Rights …

Cognitive And Behavioral Profile In A Child With Macrocerebellum - A Rare Congenital Brain Malformation, Betsy Baby, Gowthami Nair, Maniyan Lathikakumari Arya, Madhusoodanan Uranguladi, Ajina Khan, Soumya Sundaram

Journal of Pediatric Neurology

Macrocerebellum is a rare condition marked by an aberrant growth in the size of the cerebellum without any morphological or signal abnormalities. It can occur in isolation (nonsyndromic) or as part of various clinical syndromes such as Costello's syndrome, Sotos syndrome, Williams' syndrome, macrocephaly-capillary malformation syndrome, mucopolysaccharidosis, and Lhermitte–Duclos' syndrome. The most common clinical features described with macrocerebellum are developmental delay, hypotonia, ataxia, nystagmus, oculomotor apraxia, seizures, and facial dysmorphism. The exact pathophysiological basis underneath this condition is still unknown. We report the case of a 13-month-old boy who presented with developmental delay, nystagmus, and generalized hypotonia. The presence of …

Toe Walking In A Formerly Preterm Child: Is It Just Cerebral Palsy?, Nankee K. Kumar, Ashley M. Bach, Deborah M. Zarnow, Kavita Desai, Benjamin C. Kennedy, Sonika Agarwal

Journal of Pediatric Neurology

Spastic diplegic cerebral palsy (CP) is common among children born preterm and is a known cause of toe walking. By contrast, pediatric tumors of the conus medullaris are rare. We report the case of a 28-month-old formerly extremely preterm male with global developmental delay who presented with toe walking, constipation, and asymmetric hypertonia of the lower extremities. Brain imaging revealed periventricular leukomalacia, ex-vacuo ventricular dilation, and cerebellar dysplasia consistent with a diagnosis of CP secondary to perinatal injury. Lumbar spine imaging obtained due to his worsening constipation and pain while walking demonstrated an intramedullary, well-circumscribed, contrast-enhancing lesion in the conus …

Slc2a1 And Its Related Epileptic Phenotypes, Francesca Patanè, Elisa Pasquetti, Federica Sullo, Monica Tosto, Catia Romano, Stefania Salafia, Raffaele Falsaperla

Journal of Pediatric Neurology

Glucose transporter type 1 deficiency syndrome (GLUT1DS) is caused by heterozygous, mostly de novo, mutations in SLC2A1 gene encoding the glucose transporter GLUT1, the most relevant energy transporter of the brain through the blood-brain barrier. GLUT1DS includes a broad spectrum of neurologic disturbances, from severe encephalopathy with developmental delay, epilepsy, movement disorders and acquired microcephaly to atypical mild forms. For diagnosis, lumbar puncture and genetic analysis are necessary and complementary; an immediate response to ketogenic diet supports diagnosis in case of high suspicion of disease and negative exams. The ketogenic diet (KD) is the first line treatment and should be …

Aldh7a1 Gene And Its Related Pyridoxine-Dependent Epilepsy, Flavia M.C. La Mendola, Tiziana Timpanaro, Daniela Caruso, Maria Teresa Garozzo, Santiago Presti, Catia Romano, Elena R. Praticò, Antonio Zanghì, Raffaele Falsaperla

Journal of Pediatric Neurology

Despite being classically reported as caused by mutations in solute carriers genes (SLC2A1), it has been recently shown that also mutations in ALDH7A1 can cause pyridoxine-dependent epilepsy (PDE). ALDH7A1 is a gene encoding for the antiquitin, an enzyme that catalyzes the nicotinamide adenine dinucleotide-dependent dehydrogenation of L-α-aminoadipic semialdehyde/L-Δ1-piperideine 6-carboxylate. It is a highly treatable disorder, but nevertheless it is still not certain when to consider this diagnosis and how to test for it. It is possible to identify a classical form and an atypical one of PDE associated with more than 70 mutations of ALDH7A1 gene. The typical form is …

Beyond The Lawn: Bylaws For Biodiversity - Evidence-Based Recommendations For Future Practice And Policy Development, Nina-Marie Lister, Sabrina Careri Jul 2025

Beyond The Lawn: Bylaws For Biodiversity - Evidence-Based Recommendations For Future Practice And Policy Development, Nina-Marie Lister, Sabrina Careri

Cities and the Environment (CATE)

Across Canada and globally, there is growing momentum to mitigate the impacts of climate change and habitat loss on biodiversity. These challenges transcend the jurisdiction of any single government or agency. In response, people across urban areas are increasingly taking action, particularly through landscaping strategies that foster and support biodiversity at home in their gardens. In North American cities, private lands make up a significant and often majority of the urban matrix. As such, private lands offer opportunities to address anthropogenic socio-environmental impacts in cities in ways that complement municipal initiatives on public lands. Specifically, rewilding initiatives on private lands, …

District Impact On State-Wide Charter School Policy: Has Normandy Schools Collaborative Punctuated The Equilibrium? Charter School Policy Analysis Of The Missouri Department Of Elementary And Secondary Education, Tracey L. Cannon

Dissertations

Abstract

Punctuated Equilibrium Theory, as applied by Niles Eldredge and Stephen Jay Gould (1941-2002) to the study of species evolution, examined the infrequency of morphological change or stasis discontinuity.1 While groundbreaking in the field of Paleontology and the study of fossil change, the theory has been well-fitting to the decision sciences as introduced by Baumgartner and Jones2, in their 1993 and 2010 publications. Recognizing typical, incremental policy change, its use in this research looks at how stasis, stagnant policy can be punctuated by changes in political or societal views. This study examines the impact of heightened problem discussion for agenda …


Signal And Noise Analysis In An Undergraduate Instrumental Analysis Laboratory, Ken Overway Jul 2025

Signal And Noise Analysis In An Undergraduate Instrumental Analysis Laboratory, Ken Overway

Chemistry Faculty Scholarship

Understanding the difference between signal and noise in a measurement is fundamental to analytical chemists. The typical instruments found in an undergraduate chemistry department can be used to teach this concept, as well as signal averaging, by giving students hands-on experience with measurements and data processing. This work presents an undergraduate laboratory module (homework and experiment) that provides specific instructions for using gas chromatographs, fluorometers, a nuclear magnetic resonance spectrometer, an atomic absorption spectrophotometer, and an infrared spectrometer to collect replicate measurements and a framework for calculating the noise level, baseline, signal level, signal-to-noise ratio (SNR), and the signal thresholds …

The Criminal Record As A Death Sentence: Unmasking The Ignored Realities Of Formerly Incarcerated University Graduates On Professional Licencing Challenges, Mbongiseni Mdakane, Bongani Innocent Nkambule, Sindile Amina Ngubane

Journal of Prison Education Research

Recently it is increasingly common practice for universities and professional registration councils to probe into applicants’ criminal records as a precondition for admission. Using social constructionism, this qualitative study explored the experiences of six formerly incarcerated individuals previously sentenced to life imprisonment, who hold professional university degrees in Law, Education, Psychology and Social Work and investigated whether having a criminal record had any bearing when applying for professional registration. The results indicate that due to the perceived stigma of, and discrimination against a criminal record, there exist varying degrees of criminal record disclosure ranging from partial, to full and non-disclosure. …

Zkipv: Zero-Knowledge Proofs For Image Provenance Verification, Bibek Ghosh Jul 2025

Zkipv: Zero-Knowledge Proofs For Image Provenance Verification, Bibek Ghosh

Master’s Dissertations

Recent advances in generative AI have significantly improved the ability to create photorealistic synthetic images, including so-called deepfakes, raising concerns about misinformation and the erosion of trust in digital media. Ensuring the integrity and authenticity of images, especially in sensitive domains like journalism, is thus increasingly critical. Existing solutions such as the C2PA (Content Provenance and Authenticity) framework provide origin verification through cameragenerated digital signatures, but fail to account for image modifications that invalidate these signatures. To address this limitation, we propose a zero-knowledge approach to verifiable image editing that preserves both integrity and privacy. This system, ZK-IPV, introduces a …

Preparation And Properties Of Rutin-Casein Complexes, Zhang Nan, Liu Lili, Yang Le, Li Sisi, Zhang Xinyuan Jul 2025

Preparation And Properties Of Rutin-Casein Complexes, Zhang Nan, Liu Lili, Yang Le, Li Sisi, Zhang Xinyuan

Food and Machinery

[Objective] To investigate the effect of complexes produced by protein -polyphenol interaction on the bioavailability of polyphenols and proteins.[Methods] Rutin -casein complexes are prepared using rutin and casein as raw materials.Their physicochemical and structural properties are analyzed.[Results]] The optimal preparation conditions for the rutin -casein complexes are determined as follows:mass ratio of rutin to casein =1.89∶1.00,reaction time of 5.94 h,pH 8.5,and temperature of 50 ℃.Under such conditions,the binding degree is 40.23%.Compared with casein,the complexes exhibit a decrease in emulsifying activity index (8.47 m2/g) and emulsifying stability (9.39%).The solubility increases by 5.11%,surface hydrophobicity is significantly enhanced,and antioxidant activity markedly improves (P<0.05).Scanning electron microscopy reveals that the rutin -casein complexes display a lamellar structure with smooth surfaces,which may contribute to its functional properties.Infrared spectroscopy demonstrates peak broadening and redshifts in the amide I and II bands,and fluorescence intensity (including synchronous fluorescence ) decreases due to fluorescence quenching.It indicates that rutin alters the secondary structure and conformational arrangement of casein.[Conclusion] Compared with the uncomplexed casein,the rutin -casein complexes are enhanced in solubility,surface hydrophobicity,and antioxidant activity.引用格式:张楠,刘丽莉,杨乐,等.芦丁—酪蛋白复合物的制备及特性研究 [J].食品与机械,2025,41(7):9-17.C itation:ZHANG Nan,LIU Lili,YANG Le,et al.Preparation and properties of rutin-casein complexes [J].Food & Machinery,2025,41(7):9-17.
