title: Optical full Hadamard matrix multiplexing and noise effects

authors: Streeter, Lee

subjects: Hadamard multiplexing

abstract: Hadamard multiplexing provides a considerable SNR boost over additive random noise but Poisson noise such as photon noise reduces the boost. We develop the theory for full H-matrix Hadamard transform imaging under additive and Poisson noise effects. We show that H-matrix encoding results in no effect on average on the noise level due to Poisson noise sources while preferentially reducing additive noise. We use this result to explain the wavelength-dependent varying SNR boost in a Hadamard hyperspectral imager and argue that such a preferential boost is useful when the main noise source is indeterminant or varying.

title: Defamiliarizing heavy-contact sports: A critical examination of rugby, discipline, and pleasure

authors: Pringle, Richard

subjects: sports

abstract: Pleasure can be regarded as a productive force in the constitution of the social sig-nificance of sport and desiring sport subjects. The organization and use of sport plea-sure has been a relatively marginalized topic of examination. To promote and examine sport pleasure, I conducted semistructured interviews with seven passionate rugby players. Transcripts were analyzed via Foucauldian theorizing and revealed the inter-twined workings of technologies of dominance and self in the constitution of rugby pleasures. As a strategy to defamiliarize and disrupt habitual and uncritical accep-tance of rugby aggression, I argued that rugby pleasures were akin to sadomasochism. Rugby can be understood as a taboo-breaking game associated with transparent rela-tions of power connected with the pleasure induced from physical domination and the fear of pain.

title: The importance of whakapapa for understanding fertility

authors: Rarere, Moana

abstract: The Māori fertility transition—which saw a shift from high to low birth rates between 1966 to 1976—was one of the most rapid fertility declines observed anywhere in the world. Since then, Māori fertility has hovered around replacement level (2.1 births per woman), somewhat above that of Pākehā (European) New Zealanders. More striking are differences in timing with Māori women bearing their children younger and over a longer duration. This paper sits within a broader research project that asks: What are the important influences that have sustained contemporary Māori fertility patterns? Drawing on Mana Wahine (Māori women’s discourses) and whakawhiti kōrero (interviews) with wāhine Māori (Māori women) this paper highlights whakapapa (genealogy) as an important concept in broadening and deepening our understandings of fertility, and situating individual fertility and reproduction within a broader set of relations.
