Near-death experiences and the measurement of blood gases

Although cerebral anoxia is not thought to be responsible for triggering near-death experiences (NDEs), the issue is not so clear in the case of hypercapnia. Detection of normal blood gases in Michael Sabom's (1982) case study seems to be the major reply to suggestions that hypercapnia may have a causal role in NDEs. We argue, however, that routine arterial measures of blood gases are not a reliable indicator of cerebral levels.     

Agricultural policy and strategic investment in information technology

In this article the perspective shifts to the “upstream” end of the agricultural knowledge and information system (AKIS). Because knowledge policy and strategic decision-making are not the prerogative of the public sector, organizations such as cooperative unions and multinational companies are included. After considering the influence of the changing environment on the nature of the AKIS, the role of knowledge management and policy in the emerging knowledge and information market is examined. Special attention is given to public and private R&D. The article then looks where information technology (IT) fits in and what considerations determine strategic investment in IT projects and sustained services. Some of the European experiences with this strategic investment are evaluated.     

Behavioral knowledge among direct care staff in an inpatient psychiatric setting

Despite demonstrations of the utility and cost effectiveness of behavioral programming, such techniques are not commonly employed in psychiatric inpatient settings. Several explanations for this have been proposed, including inadequate levels of training and competence in behavioral programming among prevalent treatment staff. This study employed a multiple choice inventory to assess behavioral knowledge among subjects representing several direct care disciplines commonly found in inpatient psychiatric settings. The results support assertions of relatively low levels of behavioral knowledge among disciplines that are most prevalent in such settings. The implications of these results for initiatives to enhance behavioral knowledge and skills are discussed.     

Taming the Heathkit-Votrax speech synthesizer

Three inexpensive text-to-speech synthesizers are described, intelligibility data from a pilot experiment are reported, and software is offered that has been written to facilitate the phonemic programming of the Heathkit-Votrax synthesizer.
