title: Seasonal variation of biomass and bioactive alkaloid content of goldenseal, Hydrastis canadensis

authors: Douglas, James A.

subjects: Hydrastis canadensis

abstract: Seasonal variations in biomass and alkaloid contents of goldenseal (Hydrastis canadensis) were investigated. Five-year-old plants gave 5× the yield of roots and rhizomes of two-year-old plants, and summer growth gave significant increases in root biomass but not rhizomes. Berberine contents of roots plus rhizomes did not vary significantly and were > 3.4% in all samples. Hydrastine contents of 5 y roots plus rhizomes showed significant seasonal variation. These variations were due to significant changes in the hydrastine contents of the roots (1.3–1.9%), but not the rhizomes (2.2–2.8%). Goldenseal leaves plus stems had lower contents of hydrastine (0.4–0.8%) and berberine (1.0–1.5%).

title: Evaluating universal design of built environments: an empirical study of stakeholder practice and perceptions

authors: Watchorn, Valerie

abstract: Universal design aims to reduce environmental barriers and enhance usability of buildings for all people, particularly those with disabilities. There are known challenges relating to the evaluation of universal design and evidence supporting this concept is limited. This study aimed to gather information on current practice and what stakeholders perceive as important to universal design evaluation. A mixed methods approach was employed, and data were collected via online survey (n = 157) and semi-structured interviews (n = 37). Participants included industry professionals, policy makers, government officials, academics, and people with disabilities. Just over one-third of participants stated that they had experience of evaluating universal design in public built environments. Checklists were most commonly used, yet participants expressed concern with their suitability for this purpose. Almost all participants perceived evaluation of universal design as important, citing its value to advocacy, professional development and strengthening the evidence base of universal design. Findings from this study highlight a tension between a desire for efficiency and consistency, as offered by a checklist approach, and the adoption of a holistic and multidisciplinary method of evaluation that encompasses the complexity of universal design application.

title: Mā hea (which way)? Mō te aha (what for)? Too many questions, not enough answers, for Māori on the march

authors: Te Awekotuku, Ngahuia

subjects: Aotearoa/New Zealand

abstract: This presentation will be in four sections. The first section introduces two major issues: mana motuhake, and mana tāngata, then we will consider some proposed legislation: the Foreshore and Seabed Bill and the Civil Union Bill. Then I will look at strategic Māori responses to political pressure over the last three decades and note two recent and dramatic examples – the Hīkoi Takutai Moana, April 2004, and the Enough is Enough Rally, August 2004. The final section considers the implications for psychologies and psychologists working today in Aotearoa.
