title: Estimating replicability of classifier learning experiments

authors: Bouckaert, Remco R.

subjects: computer science

abstract: Replicability of machine learning experiments measures how likely it is that the outcome of one experiment is repeated when performed with a different randomization of the data. In this paper, we present an estimator of replicability of an experiment that is efficient. More precisely, the estimator is unbiased and has lowest variance in the class of estimators formed by a linear combination of outcomes of experiments on a given data set. We gathered empirical data for comparing experiments consisting of different sampling schemes and hypothesis tests. Both factors are shown to have an impact on replicability of experiments. The data suggests that sign tests should not be used due to low replicability. Ranked sum tests show better performance, but the combination of a sorted runs sampling scheme with a t-test gives the most desirable performance judged on Type I and II error and replicability.

title: Constructing global business networks in China

authors: Ding, Qiang

subjects: business networks

abstract: This article explains the issue of business networking for foreign multinational enterprises (MNEs) operating in China from various perspectives (including cultural, political, economic, and marketing perspectives). The article seeks to provide a basic platform for comparing business network development with corruption to clearly differentiate between these two concepts. The article clarifies how foreign MNEs can effectively establish and maintain business networks to navigate their way through the complex institutions in China and local networks. The article suggests that developing a business network strategy could add value to activities of MNEs in China. Although not all established business networks will definitely lead to new opportunities or bring about greater competitive advantages, an ineffective business network strategy may actually reduce the ability of foreign MNEs to achieve performance outcomes in China. An analysis of the business network strategy would be invaluable to help foreign MNEs to develop business operations in China effectively.

title: Waiata anthems: How Aotearoa (New Zealand) popular and contemporary music is addressing generational trauma and revitalising te reo Māori (the Māori language)

authors: Walker, Alroy

abstract: Waiata is translated as song or chant from te reo Māori (the Māori language), yet it has many forms and important functions in te ao Māori (the Māori world). Waiata is most commonly experienced publicly in Aotearoa in support of whaikõrero (oration, formal speech-making), but it also serves to reinforce Māori interconnectedness to others, the natural world and to the supernatural world. Enduring from pre-encounter oral culture, waiata serve as vessels and a mode of transmission for mātauranga Māori (Māori knowledge), histories (whanau, iwi) and culture. This presentation focuses on emergent and contemporary modes of waiata (punk, hardcore and indie) in a post-colonial context, examining musician motivations, the role that music plays in the revitalisation of te reo Māori, and how it honours the purpose of waiata tawhito (traditional waiata). The project is part of ongoing research supported by the partnership agreement between Prifysgol Caerdydd and University of Waikato.
