title: Metallacyclic platinum(II) bis(sulfonamides)

authors: Evans, Cameron

subjects: Platinum(II) complexes

abstract: A series of metallacyclic platinum(II) bis(sulfonamido) complexes have been synthesised by reaction of cis-[PtCl₂L₂] [L_PPh₃or L₂_1,5-cyclo-octadiene (cod)] with the sulfonamides [RSO₂NHCH₂CH₂NHSO₂R, RSO₂NHCH₂CHMeNHSO₂R or RSO₂NHC₆H₄NHSO₂R; R_Ph or p-C₆H₄Me] and Ag₂O. The products have been characterised by NMR spectroscopy, electrospray mass spectrometry, elemental analysis, and for the complexes [Pt{N(SO₂Ph)CH₂CH₂N(SO₂Ph)}(PPh₃)₂] and [Pt{N(SO₂Ph)C₆H₄N(SO₂Ph)}(cod)], by single-crystal X-ray structure determinations. In both of these complexes, one of the amido nitrogen atoms has the expected approximately planar geometry, but the other nitrogen atom is surprisingly distorted towards a tetrahedral geometry. The more pyramidal nitrogen has a higher trans-influence in the solid state, reflected by a shorter Pt_N bond, and longer cyclo-octadiene Pt_C bond length trans to this nitrogen.

title: A Village in my Hand

authors: Russell, Phillippa Jane

subjects: Samoa

abstract: Since its arrival, the cell phone has been transforming culture and the ways in which we live, exist and interact with life. With minimal access to telecommunications, since 2006 it has become ubiquitous in Samoa. 
Using observation and semi-structured interviews based within two villages in rural Samoa, this thesis has explored the influence of the cell phone upon Samoan daily lives. It investigates how it came to be in Samoa, what perceptions surround the cell phone and how it is seen to have contributed and influenced daily activities, culture and customs of villagers.
Similar to research and literature into mobile telephony on other cultures, affordances provided through the cell phone such as micro coordination and increased connectedness are also being experienced in Samoa, reducing time and space and facilitating activities that required a fair amount of coordination into activities of micro-coordination, also creating greater access to economic opportunities, such as work and the possibility of entrepreneurship. Nonetheless it appears influences such as locality and social status seem to affect the degree of   use for Samoans.  
The ability to have greater privacy provided by the cell phone in combination with being able to be perpetually in contact with others across time and space predominantly through communicative methods like SMS or texting seem to be challenging traditional expectations surrounding authority especially around familial relationships. What looks to be the difference between similar experiences in other cultures is the speed to which this technological affordance has been integrated within rural Samoa which had no previous telecommunication availability prior to 2006.  This combined with the absolute social and customary expectations placed on the values of obedience, respect, love, selfless service and Christianity appears to be accentuating the ‘loss of parental control’. 
Traditional  customs such as gift giving have been adapted by the service provider and  transferred into the use and practice surrounding the cell phone into daily activity and use by Samoans resulting predominately in the transference of money but does also include the gifting of cell phones. 
Crossing multiple disciplines this thesis explores a number of topics surrounding the cell phone and highlights the need for   further research establishing a primary base from which to build upon.

title: Adolescent Māori mothers experiences with social support during pregnancy, birth and motherhood and their participation in education

authors: Rawiri, Casey

subjects: social support

abstract: The purpose of this research was to investigate the role of social support in helping
adolescent Māori mothers cope with pregnancy, birth and motherhood, with a
particular emphasis on its role in enabling them to continue at school. The aim of this
research is to understand and make sense of these experiences and to perhaps identify
gaps within an individual's social network. The analysis and methodology of the
research was underpinned by a community psychology framework.
Nine interviews were conducted with young Māori women who had become pregnant
and continued with their pregnancy, all before the age of 20. The in depth interviews
included questions focusing on the young women learning of pregnancy, the
pregnancy, birth, caring for their child and their experiences with education and future
plans.
Negative experiences were usually those which involved unsupportive people.
Positive interactions were those where support, of all types, was offered and useful to
my participants and their children. Education was highlighted as the most effective
way of providing a better life for adolescent mothers and their children.
The research highlights the importance of social support and the continuation of
education. Combining the efforts of positive social networks and social support
services can improve the lives of adolescent Māori mothers and their children.
