Customizable Vr Driving Experiences: Balancing User Comfort And Interactivity, Kaihao Tian

Dartmouth College Master’s Theses

Driving games and vehicle simulations have been a prominent genre in the gaming world, thriving on traditional platforms like consoles and PCs. Despite the advances in virtual reality (VR) technology, the genre has seen limited success in VR, largely due to challenges in balancing user comfort, immersion, and the physical constraints of VR hardware. The primary issue arises from the conflicting goals of interactivity and comfort. While VR offers an immersive, high-speed experience with dynamic steering and rapid movements, these same elements often cause discomfort and cybersickness, undermining the very immersion that VR promises.

The recovered archaeological materials include domestic and wild fauna remains, potsherds and lithic artefacts, ochre, and stone enclosures, dating between 7200 and 4900 BP. In the East African Rift System (EARS), conventional ages for Neolithic Cultures are inferred from the most extensively researched Neolithic sites in Kenya, where the oldest Nderit ware, cattle and caprine in the Lake Turkana Basin, northern Kenya, date ca. 5200 BP. Studies on the Neolithic of EARS have been structured to fit into the migration or diffusion models that consider the spread of …

Smallpox Outbreaks And Immunization Policies In Tanzania From The Late Nineteenth Century To The First World War, Lorne Larson

Zamani: A Journal of African Historical Studies

An estimated 300 million people died globally from smallpox in the 20th century alone. There was very much a North/South divide in the existence of the disease in that period, with countries across South America, Africa and Asia recording the majority of cases. In 1966 the World Health Organization launched an intensive effort to finally eliminate the disease. The last known endemic case of smallpox was reported in Somalia in 1977, and that outbreak was promptly contained. In 1980 smallpox was declared eradicated – the only infectious disease affecting humans to achieve this distinction. This remains among the most notable …

'Evading The Tax Collector’: Native Responses To The Head Tax In Colonial Njombe, Tanzania, 1920-1960, Peter Chaula, Hezron Kangalawe

Revisiting African Religion As An Academic Discipline In Africa: History And Prospects, Ivan B. Kivinge

Zamani: A Journal of African Historical Studies

Three main religious traditions—indigenous African beliefs and practices (African religion), Christianity and Islam—have dominated everyday life of communities in Africa today. Scholarship on religion indicates that only African religion originated in Africa— Christianity and Islam are foreign religions. Many Africans today have been active Christians and Muslims, who are sometimes being misleadingly taught that African religion is demonic and forms of paganism. This article employs historical and philosophical approaches to show how the study of African religion has navigated through various historical currents and resultant implications on the way the current generation views it. In the end, the article proposes …

Review Of Water Brings No Harm: Management Knowledge And The Struggle For Waters Of Kilimanjaro, Maxmillian J. Chuhila

Zamani: A Journal of African Historical Studies

Water Brings No Harm is a key text that enables readers to understand the competing claims to resource control between government authorities and local communities on the ground. Scholarship on the relationship between local knowledge and expert knowledge in resource management and control suggests an asymmetrical relationship in which expert opinion assumes the primary responsibility.1 Bender contrasts traditional and imposed systems of resource ownership and management, arguing that there has been a struggle from both sides, as each side believes it has a rightful claim to ownership and management of water source.

Review Of Decolonising Sociology: An Introduction, Armstrong K. Matogwa

Zamani: A Journal of African Historical Studies

Decolonizing Sociology is one of the few works in sociology that makes critical assessment of the discipline. It is a kind of self-critique within the discipline that aims to reveal epistemic setbacks that have existed for decades. To arrive to the point, Meghji, has situated his thesis along decolonial sociology, which interrogates dominant sociological theories in the context of imperialism. By so doing, he makes three main arguments as follows; first, what is called sociology is colonial in nature as it is based on the ideas of the Western thinkers namely Marx, Durkheim and Weber which emerged and institutionalized during …

Legal Provisions And Administration Of Land Disputes In Kiteto District, Ca. 1970s – 2000s: The Missing Linkage, Juma Marmo

Zamani: A Journal of African Historical Studies

There have been a series of legal interventions on land use in the post-colonial Tanzania to create a good land administration and management in order to end land use conflicts. Scholarship on the legal aspect of land use indicates that legal interventions did not provide lasting solutions to land use conflicts because of their structural and systemic arrangements. In addition, existing scholarship has little focus on the linkage between law enforcement machinery, the peoples’ level of understanding on land laws, and the occurrence of land use conflicts. This paper discusses the violation of laws by peasants, pastoralists, and government officials …
