The ancient Greek economy: markets, households, and city-states
This volume draws together contributions by historians, economists, and archaeologists on the question of the role of markets in the economy of the Greek city-states during the classical and hellenistic periods
Building Brains for Bodies
We describe a project to capitalize on newly available levels of computational resources in order to understand human cognition. We will build an integrated physical system including vision, sound input and output, and dextrous manipulation, all controlled by a continuously operating large scale parallel MIMD computer. The resulting system will learn to "think'' by building on its bodily experiences to accomplish progressively more abstract tasks. Past experience suggests that in attempting to build such an integrated system we will have to fundamentally change the way artificial intelligence, cognitive science, linguistics, and philosophy think about the organization of intelligence. We expect to be able to better reconcile the theories that will be developed with current work in neuroscience
Gauging Newton's Law
We derive both Lagrangian and Hamiltonian mechanics as gauge theories of
Newtonian mechanics. Systematic development of the distinct symmetries of
dynamics and measurement suggest that gauge theory may be motivated as a
reconciliation of dynamics with measurement. Applying this principle to
Newton's law with the simplest measurement theory leads to Lagrangian
mechanics, while use of conformal measurement theory leads to Hamilton's
equations.Comment: 44 pages, no figures, LaTe
Expectations of youth victims of violence regarding healthcare professionals leading them to wellness in South Africa
BACKGROUND: Many youth victims of violence report for treatment at the health care facilities in the Western Cape Province of South Africa. It was unclear what the youth expected regarding how they could be led towards wellness by health care professionals following an incident of violence (R1.1).
OBJECTIVES: This study sought to explore and describe the expectations of the youth victims of violence with regards to health care professionals (R1.2) leading them to wellness in a selected rural community.
METHOD: A qualitative, exploratory, descriptive and contextual design was used. Nine focus group discussions were conducted with 58 (23 males, 35 females) purposefully selected youth victims of violence between the ages of 15 and 19. Data analysis was done through open coding. Ethics clearance was received from the University Ethics Committee prior to the study being conducted.
RESULTS: Findings indicated that the youth victims of violence expect the health care
professionals (professional nurses, doctors and social workers) working in their community to act as role models, demonstrate a professional attitude, provide health education, provide confidential counselling services, and establish school and community outreach programmes.
CONCLUSION: This study provides evidence that youth victims of violence have important
expectations from health care professionals concerning their wellness. Hence, health care professionals should focus on designing and implementing interventions targeting these expectations.Department of HE and Training approved lis
Psychological symptoms
Psychological symptoms are highly prevalent in people requiring palliative care. They are much more challenging to elicit, and more controversy exists about what is normal and what might require intervention than physical symptoms. There are significant issues in determining what is normal and what is not. Sadness, distress, anxiety, and depression can coexist and require careful assessment. Management of psychological symptoms and conditions can broadly be considered in terms of non-pharmacological and pharmacological therapies, “the talking and the drug therapies.” These are not mutually exclusive, and for people with limited energy, failing cognition, and limited time, some pragmatic decisions may be necessary. To be distressed and immobilized by emotion is not normal. Depression is not a normal part of dying. There should be discussion about the nature of psychological issues and conditions, explanation of common somatic symptoms, and a plan for intervention and support. The burden on the carer, both professional and personal, in such situations should not be underestimated.Gregory B. Crawfor
