A dehydrogenase catalyzing the oxidation of glucose-6-plhosphate by triphosphopyridine nucleotide (TPN) has been shown to be widely distributed in higher plants (2,5). This finding suggested that plants might form pentose by a TPN-dependent, two-step oxidation sequence similar to that already described in other organisms (6,8,17) (16), was not more than 0.03 MM per mg., and the glucose-6-phosphate content. according to assay with glucose-6-phosphate dehydrogenase (11) was 0.08 to 0.13 1MM per mg. of the barium salt. The phosphogluconate content was calculated from the organic phosphorus content, after correction for the impurities. Ribose-5-phosphate was prepared by acid hydrolysis of adenylic acid or adenosine triphosphate according to the procedure described by LEPAGE and UMBREIT (12)
The Problem. Shared leadership in teams has been the topic of substantial research in the last several years fueled, at least in part, by Pearce and Conger's helpful volume. The published literature is fragmented, complex, and difficult to navigate, making it challenging to quickly or easily gain a clear understanding of the progress that has been made and the findings that are relevant to shared leadership in teams.
The Solution.This article describes and discusses recently published empirical evidence in an effort to summarize what is known about shared leadership in teams. Questions of shared leadership's effectiveness, what is shared, with whom, and how leadership is shared are addressed. The article concludes with a summary of what we now know about shared leadership and recommendations for Human Resource Development (HRD) professionals who are involved with or responsible for developing shared leadership in teams. The Stakeholders.
Health in Northern Ontario is poorer than in the province of Ontario. Late childhood is the period in which adult habits and health behaviours are solidified, thus, health indicators are important to guide the development and implementation of disease prevention strategies. The Northern Ontario Child and Youth Health Report evaluated the health of children in Northern Ontario. The importance of public health planning is presented with the value of health status information for youth. The hospitalization rate for Northern Ontario youths was higher than for Ontario. In both areas, injuries and poisonings were the leading cause of hospitalization (7-13 year olds), however rates in the North were higher. Hospitalizations for injuries and poisonings were double the provincial rate in 14-19 year olds. The mortality rate for all youth was significantly higher. Health risk behaviour prevalence (e.g., alcohol consumption) was higher in the region. Current data emphasize the need for primordial and primary prevention in regional health planning and are also useful in secondary and tertiary prevention. Data for public health planning is critical to address population health needs and prevent chronic diseases.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
