Obstructing finite surgery

For a fixed p, there are only finitely many elliptic 3-manifolds given by p/q-surgery on a knot in S^3. We prove this result by using the Heegaard Floer correction terms (d-invariants) to obstruct elliptic manifolds from arising as knot surgery.Comment: 16 page

Frontotemporal dementia: the impact of patient behavioral symptoms on the physical and mental health of family caregivers.

BackgroundProviding informal support to someone with frontotemporal dementia (FTD) could be very stressful. Clarifying the relationship between patient behavioral problems and caregiver health could spur future research on effective symptom management strategies.MethodsSixty-one FTD family caregivers participated in a postal survey.ResultsPatient symptom severity was negatively associated with caregiver mental health (r = -0.26, p < 0.05) but not significantly associated with caregiver physical health. In a regression analysis, caregiver emotional distress from patient behaviors made a statistically significant contribution to caregiver mental health, explaining approximately 10% of its variance.ConclusionThis study underscores the importance of focusing on FTD caregivers' perceived emotional distress from patient behavioral problems and ensuring they are getting the appropriate support they need

Incorporation of tritiated cytidine into ribonucleic acid by isolated pea nuclei

A new method for the isolation of the nuclei from plant tissue has been devised. This method consists in passing the plant tissue through a set of spring-loaded, counter-rotating rollers and collecting the liberated nuclei in sucrose solution containing calcium ions. A semi-automatic machine which couples the rollers with a special tissue chopping device has been constructed. It has been shown that nuclei obtained in this way actively incorporate cytidine-H3 into RNA. This incorporation is increased in the presence of nucleoside triphosphates and an energy-regenerating system

The Development of Approaches to Curriculum Planning to Meet Academic and Professional Objectives

The importance of developing a curriculum which satisfies the broad objectives of professional education has been recognized widely. The balance between enhancing scholarship and developing vocational skills, the importance of relevant evaluation of the curriculum, students and teachers and the place of research in current professional education are all matters worthy of consideration by those responsible for professional education. This paper reflects upon the historic attitudes to education and traces the changes in approach which have been necessary to ensure the provision of appropriate learning experiences for students seeking a professional education today

Changes in the pronunciation of Māori and implications for teachers and learners of Māori

This paper discusses changes in the pronunciation of Māori and implications for teachers and learners of Māori. Data on changes in the pronunciation of Māori derives from the MAONZE project (Māori and New Zealand English with support from the Marsden fund). The project uses recordings from three sets of speakers to track changes in the pronunciation of Māori and evaluate influence from English. Results from the project show changes in both vowel quality and vowel duration and some evidence of diphthong mergers in pairs such as ai/ae and ou/au, especially amongst the younger speakers. In terms of duration the younger speakers are producing smaller length distinctions between long/short vowel pairs other than /ā, a/. We discuss the implications of such changes for those teaching Māori and for students learning Māori as a subject. These changes raise interesting questions concerning the pronunciation of Māori by future generations
