title: Preparation and tensile properties of guar gum hydrogel films

authors: Jussen, Daniel

abstract: Guar gum hydrogels may be dried to form polymer films which have the potential for use as biodegradable alternatives to polymers such as low-density polyethylene. In this study, the tensile strength and tensile modulus of guar gel films having moisture contents ranging between 15% and 18% (wet basis) were measured at a strain rate of 1 mm min⁻¹. Mean tensile strengths of the films ranged between 25 MPa and 40 MPa (dependent on composition) which is of similar magnitude to the tensile strength data for polyethylene and cellophane that are reported in the literature. The mean tensile modulus of the films (1.5–2.5 GPa) was higher than the tensile modulus values reported for low-density polyethylene but comparable to those for cellophane (3 GPa).

title: World-view perspectives

authors: Whitehead, David

subjects: perspective

abstract: The foundation of a tolerant society is an ability to foster and
respond to the diversity of perspective among its people. Cognitive
psychologists have described how perspective influences information
processing, while our innate ability to adopt perspective has been established
by neuropsychology. Literature, through the use of point-of-view, together
with results from researchers adopting socio-cultural paradigms suggests
perspective is also a social construct. An ecologically-based framework is
described that provides cohesion to the temporal, spatial, universal and other
types of world-view perspective associated, predominantly, with indigenous
cultures. Culturally responsible types of creative and critical thinking are
evoked when world-view perspective is engaged while reading text and
reading the world. World-view perspective provides us with a means of
critiquing the construction of knowledge through the de-construction of
dominant discourses, re-valuing of indigenous world-views and reducing the
relational distance between indigenous and non-indigenous peoples.

title: Neighbours at Puhoi River: A cross-cultural dual biography of Te Hemara Tauhia(1815-1891) and Martin Krippner(1817-1894)

authors: Eddy, Anne

subjects: Cross-cultural

abstract: This thesis seeks to re-construct the biographies of two relatively obscure, yet fascinating and controversial players in the history of Aotearoa New Zealand. Both historical figures were initiators and leaders of neighbouring settlements: the rangatira, Te Hemara Tauhia (1815 – 1891), in his role as chief of the Te Kawerau/Ngāti Rongo hapū of the Ngāti Whātua iwi, re-occupying ancestral lands after living in captivity with Ngāpuhi, and the former Austrian captain, Martin Krippner (1817 – 1894), organiser of an Austrian-Bohemian settlement made possible under the Auckland Provincial Government land grant scheme. Despite their efforts for each community, both men were accused by their own people of misusing their positions for personal gains. Te Hemara Tauhia was blamed for selling off tribal lands to cover personal debts. Martin Krippner was never forgiven for promising his Bohemian compatriots a ‘land of milk and honey’ while leading them to near starvation and struggle within dense New Zealand bush, and subsequently into war in the Waikato where Krippner was commissioned captain in the Waikato Militia.
Focussing on three main objectives, this cross-cultural dual biography provides an original contribution to historical scholarship: Firstly, it looks behind the myths that have been created around Te Hemara Tauhia and Martin Krippner; it thoroughly examines what both men did and how social, economic and political circumstances influenced their motivations and choices at that particular time. Secondly, placing Tauhia’s and Krippner’s biographies side-by-side provides a novel view of a range of historical phenomena from both Tangata Whenua (indigenous peoples) and European settlers (Pākehā) perspectives. Looking at the same events from different angles and perspectives, a cross-cultural, dual biography can act like a prismatic tool, revealing the complexity of a shared history. The third aim of this research encompasses my intention to contribute to and to participate in a dialogue between ethnic groups in Aotearoa New Zealand, especially between Māori and Pākehā, in order to challenge stereotypes and generalisations based on lack of knowledge of historical and cultural contexts.
