title: Bayesian conjoint choice designs for measuring willingness to pay

authors: Vermeulen, Bart

subjects: c-optimal design

abstract: In this paper, we propose a new criterion for selecting efficient conjoint choice designs when the interest is in quantifying willingness to pay (WTP). The new criterion, which we call the WTP-optimality criterion, is based on the c-optimality criterion which is often used in the optimal experimental design literature. We use a simulation study to evaluate the designs generated using the WTP-optimality criterion and discuss the design of a real-life conjoint experiment from the literature. The results show that the new criterion leads to designs that yield more precise estimates of the WTP than Bayesian D-optimal conjoint choice designs, which are increasingly being seen as the state-of-the-art designs for conjoint choice studies, and to a substantial reduction in the occurrence of unrealistically high WTP estimates.

title: Patient journeys: Stories of mental health care from Tokanui to mental health services, 1930s to the 1980s

authors: Coleborne, Catharine

abstract: This chapter is concerned with finding out about mental health patients - taking this term at the outset - and exploring how their stories might be found in different places from 1912. It considers, then, the shifting identities of patients over time, as well as exploring issues around how historians might productively locate stories and narratives of mental illness, hospitalisation, recovery, and sometimes, cycles of these. Overall, it situates Tokanui patients in a wider framework for mental health histories in New Zealand and seeks to find their stories among the many accounts of mental illness. Where the previous chapter considered changing modalities for treatment, and told patient stories sensitively to capture this from the perspective of a practising psychiatrist, this chapter is written from the point of patients, but also mediated by the view of the historian. It therefore asks readers to think about the ways we tell stories of mental health, as much as about the stories themselves.

title: Te rima tekau ngahurutanga o Te Whare Wānanga o Waikato

authors: Dixon, Ngahuia

subjects: Tohu mātauranga

abstract: E te Whare Wānanga o Waikato – te tohu o te mātauranga, tēnā koe.  Tēnā koe i roto i tō rima tekau tau ngahurutanga.  Kua pakeke haere koe.  Kua tau atu koe ki tērā kaumātuatanga nō reira me mihi ka tika.  He hōnore nui tēnei mōu ake i te mea nāu te moana o mātauranga i roto o Waikato i tuku kia rere, kia pari, ka rere anō.  He wai marino ēnei i ētehi wā, he rehutai i ētehi atu,  he wā anō ka karekare, ka haruru rānei i te pai o te rere o āu mahi.  Ahakoa ēnei huringa o ngā awa o te wā, kei te rere tonu te moana nei, me ōna pikonga ki uru, ki rāwhiti, ki tonga, ki raki rānei, arā ki ngā pito katoa o te ao.  He mātauranga ēnei i tukuna e koe kia pīoioi i te ao.  Hei aha - hei whakawhānui ki te mātatoru o te tangata, he aha kei ō whare kōrero, hei whakakīkī haere i ā rātou kete mātauranga, ahakoa Māori, tauiwi huri noa.  Koinei ngā korowai mō ngā manu i kai i te mātauranga nāu i rumaki.   Ināianei arā te kōrero:

Nō rātou, nō mātou, nō tātou te ao 

E kore e mimiti ēnei huarahi tautoko āu, - nā mēnā ka tūwhera tonu tō ngākau ki ngā kete kōrero, mātauranga āku ake a ngāi-Māori, kei hea mai tō mana.
