title: Adversarial risk analysis for auctions using non-strategic play and level-k thinking: A general case of n bidders with regret

authors: Ejaz, Muhammad

subjects: Science & Technology

abstract: First-price sealed-bid auctions have been modeled using a utility function that takes into account bidders’ regret in case of winning or losing the auctioned item. However, that modeling does not consider bidders’ wealth which is an important determinant of bidders’ behavior in these auctions. In this paper, we apply an adversarial risk analysis approach for these auctions and find solutions using non-strategic play and level-k thinking solution concepts assuming n bidders. We define new regret parameters and a modified utility function to incorporate the effect of bidders’ wealth on their bidding behavior. In our modeling, we assume that the auctioned item is a normal item and has a reserve price. We give numerical examples to illustrate our methodology for each solution concept.

title: Narratives from the Mind's Eye: The Significance of Mental Health Pathography in New Zealand, 1980-2008.

authors: Campion, Michelle Edith

subjects: pathography

abstract: Medical narratives have dominated historical accounts of suffering, patients have also played a role in their own illness experiences. Efforts to elucidate their perspective have necessarily focused on deconstructionist readings of material produced by the medical profession. However, in recent years historians have been aided in their task by sufferers, who have begun to publish their own narratives of affliction. These accounts, called 'pathographies', are particularly significant for histories of mental health, where comprehension outside experience remains tenuous.

This thesis investigates sufferers' experiences of mental illness through an examination of fourteen New Zealand mental health pathographies, published between 1980 and 2008. It considers, not just what pathographies say, but how the way in which they say it, including the myths, language and media used, conveys the desired meaning and reflects the purpose of the narrative. Sufferers' narratives inform readers about what it is like to be ill, including what was thought, felt and done. In describing their experiences sufferers invariably discuss the illness relationships which comprise their support network. Most especially they highlight the importance of the role which family and friends play in recovery. Despite pathography's restoration of the patient's voice through the provision of a legitimate, therapeutic narrative, silences remain. Whether the result of selectivity, concealment, or forgetfulness, pathographers' silences are far from meaningless, powerfully conveying the pain, anger, embarrassment, and hurt which eludes articulation. In spite of the presence of silence this thesis argues that pathographies are a rich source of information about the position of mental illness sufferers. Yet to be fully utilised, I argue that pathographies testify to the way in which the chaotic can be ordered in a therapeutic plot which communicates the individual truth wrought by memory.

title: Everyday experiences of racism: Suppressing Māori cultural expressions in mental health

authors: Southey, Kim Marie

abstract: Tēnā kautau i runga i ngā tini āhuatanga o te wā.

This publication has been produced as part of the He Kokonga Ngākau Fellowships, an initiative of Te Atawhai o Te Ao that seeks to support and contribute to our research projects, and grow Māori research capability that promotes Kaupapa Māori research. These fellowships have been established to support Māori postgraduate students, practitioners, community researchers, and writers in their writing on kaupapa that have relevance to our organisation and wider community.

Dr Kim Southey (Ngāti Porou, Ngāti Kuia) draws on her doctoral research on re-presenting Māori and Indigenous understandings of being, and deconstructing the notion of mental illness. This
publication focuses on how Māori and Indigenous expressions within the mental (and wider) health system are suppressed and restricted by a dominant (western) worldview. Dr Southey posits that the western insistence on representing things in the world through rational, logical explanations impacts on Māori cultural understandings, limiting how we can express ourselves. This is viewed by Dr Southey as a form of institutional racism.
