Reconstructing Stand-Age Structure In A Wet Miombo Woodland Using Dendrochronology, Zambia, Clara Tiyembekeze Zulu

All-Inclusive List of Electronic Theses and Dissertations

Dendrochronological research in tropical Africa has remained limited, leaving critical gaps in stand-age structure and climate-growth relationships in seasonally dry tropical woodlands. This study reconstructed stand-age structure and assessed climate sensitivity in the wet Miombo woodland of African Explosives Limited (AEL) forest, Copperbelt Province, Zambia. Field sampling was conducted during four African Dendrochronology Fieldschools (2021-2024) using a Modified Variable Area Transect (MVAT) design across nine plots. The series intercorrelation was 0.351; the average mean sensitivity was 0.423. The oldest tree was 170 years old, and more than 70% of the sampled species showed potential for dendrochronology. Markhamia obtusifolia was the …

Paleolimnology And Diatom Taxonomy From Lake Tanganyika, Sristika Adhikari

All-Inclusive List of Electronic Theses and Dissertations

Lake Tanganyika is one of the world's largest freshwater ecosystems, supporting rich aquatic biodiversity and providing several ecosystem services to surrounding communities. Environmental changes such as rising lake surface temperatures, pollution, and land-use alterations threaten the lake’s sustainability. This research examines spatial and temporal variations in nutrient dynamics and primary productivity of Lake Tanganyika using diatom assemblages from multiple locations. Our findings indicate reduced nutrient levels and longer stratification periods in the lake’s central basin during most of the Common Era, as indicated by a remarkable increase in the relative abundance of long, needle-shaped planktonic Nitzschia species. In the southern …

Racialised Gradients Of Human Value And Marx’S Working Day, Today, Anthony F. Peressini

Philosophy Faculty Research and Publications

This paper reconsiders the ‘working day’ discussion in chapter ten of Capital and how it centres two parameters in the generation and appropriation of surplus value. The first parameter is the cost of labour-power paid by the capitalist and the second is the time that the worker must yield to the capitalist: the ‘length of the working day’. The first parameter represents the amount of pay required to keep the worker alive and able to work. Marx understood it as a lower limit below which capitalism would cease to function. This paper argues that, while analytically coherent, this understanding of …

Factors Influencing Employee Engagement And Performance In Hybrid Work Environments, Saif Alblooshi

Theses

The widespread adoption of hybrid work arrangements, in which employees divide their working time between remote and office-based settings, has fundamentally altered how organisations manage, measure, and sustain workforce engagement and performance. While hybrid models offer tangible benefits such as increased autonomy, reduced commuting burden, and greater scheduling flexibility, they simultaneously introduce a set of organisational challenges that conventional management frameworks were not designed to address. Chief among these challenges is the difficulty of maintaining consistent levels of employee engagement across distributed work settings, where informal communication, social connection, and direct managerial oversight are structurally constrained. The absence of robust, …

Preparing Undergraduates To Philosophize With Children About Mathematics, Lawrence M. Lesser

Journal of Humanistic Mathematics

This paper shares my reflections and insights from preparing and facilitating a session in a weeklong inaugural study away program for undergraduate students (especially philoophy majors). My session was a vehicle for helping these students experience or visualize how the program’s Philosophy for Children (P4C) approach could be applied to exploring and discussing mathematics with children.

Mathematicians Against The Tide, Nicola Ciccoli

Journal of Humanistic Mathematics

Mathematicians in popular culture are often depicted as people obsessed by their studies but with little connection to society, poor social skills, mental issues and narrow interests, and more generally a dull life. Adding to these explicit stereotypes, subtler and more implicit ones also abound, regarding mathematicians’ gender, ethnicity, age; they are all supposed to be white middle-aged men. In this paper I describe a project aimed at disrupting such stereotypes that culminated in a book containing short comics and biographies of twentieth-century mathematicians that were, with respect to the perceived image of mathematicians, against the tide.

Digital Transformation And Sme Economic Contribution In Saudi Arabia: A Critical Analysis Through The Dynamic Capabilities Lens, Rodrigo Bochner

Journal of King Abdulaziz University: Economics and Administration

This analytical essay examines the intersection between digital transformation initiatives and small-to-medium enterprise (SME) economic contribution within Saudi Arabia's Vision 2030 framework. Drawing upon dynamic capabilities theory and analysis of government data, academic literature, and policy documents, we explore how digital transformation intensity influences SME performance and their contribution to economic diversification objectives. Government reports reveal that SMEs in Saudi Arabia grew from 429,026 enterprises in 2016 to over 1.8 million in 2024, yet contribute only 30% to GDP versus the Vision 2030 target of 35%.

Foreword From Editors - 19th Edition: Community Stewardship Towards Sustainable Futures, Yandi Andri Yatmo, Kristanti Dewi Paramita, Rini Suryantini

ASEAN Journal of Community Engagement

The discussions highlighted from the articles in this AJCE edition focuses on the institutionalization, process, and implication of community in stewarding their living environment. Such focus expands the community engagement discourse, highlighting how the act of stewardships creates a sense of shared responsibility of actors to their shared spaces and resources. In turn, this shared responsibility enables the community to shift from passive act of participation to active empowerment, creates social cohesion, and establishes local governance. Such a shift towards active empowerment and shared responsibility is the key in building systemic resilience, towards a more sustainable future for society.

Ethnographic Insights Into Community-Based Circular Economy: The Case Of Waste Banks In Semarang, Rahoyo Rahoyo, Teti Susilowati, Sri Purwantini, Darto Sachius, Wilson M. A. Therik

ASEAN Journal of Community Engagement

The linear economy model has led to severe environmental degradation, prompting a shift toward the circular economy (CE) framework to promote sustainability. However, CE literature often overlooks grassroots, community-based initiatives in urban contexts, particularly in the Global South. This study addresses that gap by examining waste banks in Semarang, Indonesia, highlighting the critical importance of these grassroots initiatives within the broader discourse of community engagement. Using an ethnographic approach, data were collected through in-depth interviews, field observations, and open-ended survey responses across multiple community waste banks. The findings reveal the complex interdependence of four key actors—waste banks, itinerant collectors, scavengers, …

Democratization of video-sharing platforms capacitates filmmakers to break from …

Tourism, Security, And Sacred Space At Bethany Beyond The Jordan, Olivia Stockwell

Proceedings of the annual meeting of the Southern Anthropological Society

Bethany Beyond the Jordan, a UNESCO World Heritage Site advertised as the baptismal site of Jesus of Nazareth, lies on the border between Jordan and the occupied West Bank. Based on first-person observation, this article provides a semiotic analysis of how tourist spaces, commodification, and security infrastructure interact to create perceptions of sacred space. When placed in conversation with the historical and political contexts of the site, these factors provide insight into how meanings of sacrality are generated. I argue that notions of the sacred at Bethany Beyond the Jordan are shaped by tourism spaces and their organizing of ritual …

Emancipation, Decolonization, And Gender In The Context Of African Integration, Luwam Dirar

Florida Journal of International Law

The 1960s institutionalization and formalization of Africa’s continental integration was a manifestation of the ontological fragility of the concept of emancipation in the African context. As a concept, continental emancipation excluded concerns of women and formalized the divorce between decolonization and racial domination on the one hand and social emancipatory movements on the other. This divorce was contrary to the expectation of women who sought the end of colonial subjugation as a turning point for women’s emancipation from not only colonial and racial domination but also from social oppression. This Article argues that the continental emancipation project betrayed the hopes …

Charismatic Leaders Role And Challenges During Crises, Tamer Hassan Abutahoun Phd

Journal of the North American Management Society

Since the first article about charismatic leadership by Weber was issued in 1946, numerous pieces of research have been published discussing several aspects of charismatic leadership. One of these aspects is the role of the charismatic leader during crisis and whether it is being impacted by crises or emerged during crises. Several articles have been published to investigate the role of charismatic leadership during crises along with how individuals perceived charismatic leadership during crises. Most of these articles utilized case studies to investigate the former mentioned relationship. However, each of these studies investigated the relationship between crises and charismatic leadership …

From Access To Accountability: Closing The Nonprofit Data Gap In Fintech Lending, Oluwatomisin Olubakinde

Journal of Nonprofit Innovation

Financial technology is often treated as a promising path toward financial inclusion. Mobile banking, alternative credit scoring, and AI-assisted underwriting have expanded access to financial products, but access alone does not guarantee fair outcomes. This piece frames fintech accountability as a nonprofit data accessibility issue. Nonprofits working in financial inclusion cannot fully evaluate fintech referrals or partnerships when the data behind approval decisions, pricing patterns, denial reasons, and appeal pathways remain inaccessible. Drawing on research in fintech lending and algorithmic fairness, the paper shows how data inputs, model design, and approval thresholds shape who benefits from fintech and who may …
