Against the background of culture bound syndromes and the universalism/relativism debate, this research set out to investigate the diagnosis of brain fag syndrome by examining case studies in a South African context. Diagnostic criteria were identified by way of an analysis of the symptoms reported by a convenience sample of 20 black students experiencing problems related to study. In-depth case studies were conducted with three of the participants from the sample who most thoroughly met the criteria for brain fag syndrome. In a comparison between the brain fag diagnoses and the DSM-IV diagnoses, it was established that while the DSM-IV was not without merit in a cross cultural context, cultural differences were found which suggested the usefulness of the brain fag syndrome diagnosis. A speculative statement on the universalism/relativism debate was proposed based on the principle of complementarity derived from Quantum physics.

Cerebral haemodynamic status defined as cerebral vasoreactivity to carbon dioxide and pressure autoregulatory response, have been shown to be affected after traumatic brain injury (TBI) and correlate with the neurological condition and clinical outcome. Therefore, it is important to have a reliable method to determine the cerebral haemodynamic status in brain-injured patients. Blood flow velocity (BFV) measurement by transcranial Doppler ultrasonography (TCD) has been shown to give accurate indication of changes in cerebral blood flow (CBF). Transient hyperaemic response (THR) test with TCD measurement to assess the BFV response of middle cerebral artery to a brief compression of the ipsilateral carotid artery, provides a simple method for repeated assessment of the cerebrovascular autoregulatory reserve in brain injured patients. However, the test has not been validated systematically against classical assessment tests using TCD and gold standard CBF measurement. / The aims of this thesis are (1) to validate the non-invasive TCD and its haemodynamic tests with a more involved gold standard CBF measurement using stable xenon-enhanced computerized tomography. (2) To correlate the cerebral haemodynamic abnormalities with the patterns of neurochemical disturbance detected by intracerebral microdialysis. (3) To investigate the possibility to reverse or minimized the cerebral haemodynamic abnormalities and metabolic derangement by treatment. (Abstract shortened by UMI.) / The goal of intensive care management for TBI is to provide them with a favourable physiological and metabolic environment for recovery of the injured-compromised cells. The development of clinical intracerebral microdialysis has enabled documentation of the metabolic derangement that provides more understanding of the mechanism of brain damage. Continuous measurement of both neurochemical and physiological parameters including CPP defined as mean arterial blood pressure (ABP) minus intracranial pressure, BFV and CBF, enables study of the relationship between metabolic events and physiologic changes. Clinical management of patients with TBI has emphasized on maintaining an optimal cerebral perfusion pressure (CPP). This critical CPP can then be defined by TCD, CBF as well as the metabolic measurements. / Ng Chi Ping. / "June 2005." / Adviser: Wai-sang Poon. / Source: Dissertation Abstracts International, Volume: 67-01, Section: B, page: 0122. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2005 / Includes bibliographical references (p. 147-154). / Electronic reproduction.

This research investigates the drivers that pushed Returned Non Resident Indians(RNRIs) to come back to their homeland and their potential contribution, through the knowledgeand competences acquired by studying and working abroad, to the Firms that hire them.We used a qualitative method pursued through semi-structured non-standardized interviews withexperts of the topic and RNRIs. Furthermore, in order to have better insights, we looked at thebackground of the top management of 8 top IT Indian companies and at newspaper coverage.It resulted that RNRIs come back mainly to be closer to their families and because of a combinationof economic decline in the West and booming economy in India, thus leading to a better lifestyle.Moreover, we found indication of the contribution presented to Firms’ by knowledge and skills andgained interesting insights on the future trends of the Diaspora.However, our findings cannot be considered as conclusive, due to the small size of the sample wehad access to. The research topic needs further research.

The work reported here was aimed at extending previous findings suggesting that the medial and lateral substantia nigra (SN) are functionally different with regard to intracranial self-stimulation (ICSS) and circling. It was found that the effects of systemic D- and L-amphetamine on ICSS were different for medial and lateral SN sites. These differences were attributed to the presence of two subtypes of dopamine (DA) neurons in the SN. The circling results indicate that circling in opposite directions can be elicited from the medial and lateral parts of the nigrostriatal DA system from the same hemisphere suggesting that medial and lateral nigrostriatal DA have opposing roles in the expression of circling. It was further demonstrated that the superior colliculus is critical for the expression of medial SN derived circling and the midbrain reticular formation is critical for both medial and lateral SN derived circling.
