Journal of the Saudi Heart Association

Drug-coated balloons are an emerging strategy for coronary revascularization. Despite their increasing use, the comparative efficacy of sirolimus- versus paclitaxel-coated balloons (SCB vs PCB) remains uncertain. This updated meta-analysis evaluated clinical and angiographic outcomes of SCB and PCB in percutaneous coronary intervention (PCI). A comprehensive search of PubMed, Scopus, and ScienceDirect was performed on August 28, 2025. Studies directly comparing SCB and PCB were included. The primary endpoint was target lesion failure (TLF), which was defined as cardiac death, target vessel myocardial infarction (TVMI), or target lesion revascularization (TLR). On follow-up angiography, secondary endpoints consisted of minimal lumen diameter (MLD), …

Becoming Modern: Households’ Electricity Use And Coping With Power Outages In Post-Socialist Dar Es Salaam, Emanuel Lukio Mchome

Tanzania Journal of Sociology

Since its invention in the 1880s, electricity has been regarded as a pervasive driver of modern life. As scholars have shown elsewhere, ideas of modernity have influenced the provision and use of electricity in cities across the globe. By and large, scholars have examined electricity-modernism in terms of the construction of high-tech electric infrastructure by major actors. Those who have studied power failures This article examines electricity-modernism from the perspective of everyday electricity use and the experience of power outages, a lens rarely used by scholars. It draws from oral history interviews and archival sources to show how ideas of …

Mental Health And Psychosocial Well-Being Of Domestic Workers In Dar Es Salaam, Tanzania: Why It Matters And Why We Should Make It A Priority, Magolanga Shagembe

Tanzania Journal of Sociology

This phenomenological study explores the mental health and psychosocial well-being of domestic workers aged 15–18 years in Dar es Salaam, Tanzania. Drawing on Bronfenbrenner’s ecological systems theory and Erikson’s psychosocial development theory, the study examines how domestic workers negotiate self-acceptance, personal growth, purpose in life, quality of relationships, environmental control, autonomy and resilience within unequal labor and care arrangements. Data were generated through in-depth interviews with 29 domestic workers and analyzed thematically. The findings reveal that mental health and psychosocial well-being among domestic workers are shaped through complex interactions between structural vulnerability, interpersonal relationships, migration experiences, economic necessity, and future …

Abstract

The present article explores the role of Faith-Based Organizations (FBOs) in the Eastern Democratic Republic of the Congo in transforming cultural conflict within local communities. It draws on qualitative research conducted in Goma and its environs, which included key informant interviews and focus group discussions. It employs conflict transformation theory to explain the findings and illustrate how ritual reintegration, gender advocacy, theatre for conflict resolution, and interfaith dialogue influence actor recognition, moral dialogue, and local dialogue while embedded within power hierarchies and interdenominational conflicts. The article builds on the literature by adding ritual and theological ethics to conflict transformation …

Beyond The “Him-Her-Ing” Dichotomy: Unpacking Gendered Power Logics In Tanzanian Public Administration, Furaha Julius

Tanzania Journal of Sociology

Despite decades of policy commitment to gender equity in Tanzania, substantive inequality within public administration endures. This study moves beyond quantifying women's underrepresentation to investigate the discursive and performative mechanisms that sustain a gendered power logic, termed him-her-ing. Situated within post-structural feminist theory and drawing on qualitative data from 21 in-depth interviews and a critical review of policy documents, this paper reveals how administrative practices—from leadership norms to routine task allocation—continuously reproduce a binary that privileges masculine-coded authority. Findings demonstrate that ostensibly neutral bureaucratic procedures, religious and customary influences, and informal patronage networks coalesce to marginalize feminine subjectivities, even within …

Medicalisation And The Practice Of Labour Augmentation In Mwanza, Tanzania, Latifa Abdulla Mohamed, Richard Sambaiga, Karen Marie Moland, Siri Lange

Tanzania Journal of Sociology

Since the late 1900s, maternal health has increasingly been medicalised as a result of growing global concerns about poor maternal outcomes. An example of this medicalisation process is the use of oxytocin for labour augmentation. This practice of administering oxytocin to shorten the duration of labour is increasingly questioned. Feminist scholars have often questioned the routine use of oxytocin, depicting it as unnecessary and may constitute inappropriate use of the drug that undermines women’s autonomy and contributes to negative birth experiences. However, these feminist arguments overlook individual agency and the complex ways in which actors encounter and interact with oxytocin …

Public Perception Of Community Policing In Tanzania, Bernadeta Killian, William John Walwa

Tanzania Journal of Sociology

Community policing is widely recognized as a viable means to address increasing security challenges. However, security problems in Tanzania have increased even though the police force has formalized and implemented a community policing structure called Ulinzi Shirikishi (participatory security) during the past 20 years. In this paper, both qualitative and quantitative methods are applied to analyse the community perception of Ulinzi Shirikishi to determine its viability. Located in the concept of social capital, it reveals that even though the police and government have favoured the use of Ulinzi Shirikishi to organize security, it is not the most preferred security structure …

Conservation Education And The Cultivation Of Environmental Responsibility: Case Studies From Sri Lanka, Jody Miller, Pasindu Dilshan Abegunawardhana

International Journal on Responsibility

Conservation education encompasses effective pedagogical practices that enhance knowledge of the environment and foster responsible environmental actions. In addition to building an informed citizenry, conservation education is shaped by theoretical stances about the components necessary to cultivate environmental responsibility among participants and their communities. Highlighting three of our own conservation education projects in Sri Lanka as case studies, we draw from research and debates about environmental responsibility to illustrate the incorporation of environmental engagement and responsibility into these efforts, and the difficulties that arise in doing so. Sri Lanka is one of eight global biodiversity hotspots prioritized for conservation intervention. …

Khirbat Jābir: The Sculptured Decorations From The Bathhouse, Rivka Gersht

Qadum: Journal of Excavation Reports from Israel

The excavation of the bathhouse at Khirbat Jābir yielded twelve marble items: a female head and eleven architectural members; among them a small Corinthian capital, a bracket ornamented with a lion head, a richly decorated small pediment and a champlevé revetment plaque. All twelve items were found out of their original display context; almost all are reused spolia or recycled pieces. The workmanship of the recycled items indicates that the craftsmen employed at the Khirbat Jābir bathhouse were skilled stone carvers but had no experience in shaping figural images. The rather good workmanship of the capital and the champlevé revetment …

Pseudodifferential Absorbing Boundary Conditions For Waves, Lauren Taylor

Mechanical Engineering Theses

Absorbing boundary conditions (ABCs) are required to truncate the computational domain when performing Finite Element Analyses of exterior acoustic problems where physical domain is unbounded. ABC is applied on a fictitious boundary containing the scatterer and ideally allows outgoing waves to leave without non-physical reflections. Preventing artificial reflections is essential to benefit from the accuracy of the numerical method used. Otherwise, ABC acts as a reflective surface, and artificial reflections distort the solution in the entire domain which is not recoverable by any type of refinement. Pseudodifferential ABCs were used to describe the Dirichlet-to-Neumann map which maps known boundary values …

Beyond The Cycle: How Menstruation Influences Gender Identity And Well-Being In Binary And Non-Binary Adults, Rin Nguyen

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Approximately 1.8 billion people worldwide menstruate, including transgender and gender-diverse (TGD) people, yet their experiences remain underrepresented in research. Given that menstruation can affect gender alignment and psychological well-being, understanding its impact on TGD people is critical. Gender congruence, or alignment between one’s gender identity and expression, is a key factor influencing well-being, with research linking it to reduced depression and anxiety. Furthermore, emerging research on gender euphoria, the joy experienced when gender congruence is experienced, suggests it may serve as a protective factor for mental health and well-being. Gender euphoria has been associated with reduced psychological distress and increased …

Educating School Nurses On Trauma-Informed Care, Na-Keisha Allene White

Walden Dissertations and Doctoral Studies

Trauma-informed care is a critical component of supporting students' overall wellness, and school nurses are central to this work. They are often the first professionals to recognize when a student is exhibiting a trauma response or experiencing a mental health concern during the school day. Although evidence-based school health organizations have advanced efforts to ensure that academic environments are prepared to support students’ mental health needs, school nurses are too often left out of these strategic planning processes. Their exclusion not only overlooks their clinical expertise but also weakens the school’s ability to respond effectively and holistically to student needs. …

Serial Drilling Technique For Sequential Subtrochanteric Femur Fracture Fixation In Pediatric Osteopetrosis: A Technical Report., Adam Mansour, Josiah J Wolf, Ivan Slyepkan, Morgan Turnow, Michael Anderson, Anthony Wing, Jack Iandoli, Craig Goubeaux, Craig Smith, Allen Kadado

Surgery Articles

Pediatric osteopetrosis presents a significant technical challenge for fracture fixation due to the bone's dense yet brittle nature and frequently absent medullary canal. Traditional drilling methods risk excessive torque, drill-bit breakage, and iatrogenic fractures. Here, we describe a serial drilling technique for plate-and-screw fixation in a 5-year-old child with osteopetrosis who sustained sequential subtrochanteric femur fractures 8 months apart. By creating a small pilot hole, sequentially enlarging it with intermediate bits under copious irrigation, and inserting locking screws manually, we achieved stable fixation with no observed instrument failure or intraoperative complications. This method may provide a practical technical strategy for …

Department of Anesthesiology Faculty Papers

Proteins contain small pockets that form due to imperfections in residue packing or the rotational and conformational movement of amino acids. In this work, we used the fluorescent probe 1-aminoanthracene (AMA) to detect a small ligand pocket in the hydrophobic core of human proliferating cell nuclear antigen (PCNA), which is a critical protein for DNA replication and repair. Fluorescence measurements of AMA reported that the core of PCNA had a dielectric constant (ε) of 4, which was very apolar and similar to cyclohexane (ε = 2). Protein mutagenesis, photoaffinity labeling, and molecular dynamics simulations localized the binding site for AMA …
