title: Combining Naive Bayes and Decision Tables

authors: Hall, Mark A.

subjects: computer science

abstract: We investigate a simple semi-naive Bayesian ranking method that combine naive Bayes with induction of decision tables. Naive Bayes and decision tables can both be trained efficientyly, and the same holds true for the combined semi-naive model. We show that the resulting ranker, compared to either component technique, frequently significantly increases AUC. For some datasets it significantly improves on both techniques. This is also the case when attribute selection is performed in naive Bayes and its semi-naive variant.

title: Involvement in political issues by people living in the Te Aroha district

authors: Hart, Philip

abstract: As only a minority of residents were enthusiastically interested in national political issues, efforts to encourage debates about such issues by forming clubs largely failed. There was much more interest in local politics, where many of the conflicts were personal rather than political. 
Many illustrations are given of the fervent patriotism of residents and of their loyalty to queen and empire, which included support for all the empire’s wars. Both the Boer War and the First World War provoked much patriotic fervour, those who did not fight doing their best to assist the cause of empire by fund-raising. In the former war, disapproval of ‘pro-Boers’ was common, but the right of ‘non-Britishers’ to dissent was supported by some residents. When the Dreyfus affair was at its height, Te Aroha achieved considerable notoriety for its method of supporting this unjustly accused man. Concerning Ireland, many supported the downtrodden Irish by contributing funds to assist evicted peasants. 
Examples are given of those who supported the liberal and conservative sides in national politics. Some of those involved in the mining industry stood for parliament before withdrawing in favour of more prominent politicians, and 13 investors became Members of Parliament.

title: Low copper levels measured in the aortic wall of New Zealand patients with non-syndromic ascending thoracic aortic aneurysm

authors: El-Gamel, Adam

subjects: Ascending aortic aneurysm

abstract: OBJECTIVES: Studies in animals have shown causal relationships between copper (Cu) deficiency and the development of thoracic aortic aneurysms (TAAs) [1, 2]. Cu deficiency is widespread in New Zealand (NZ) soils; the high soil pH from the use of lime fertilizers reduces the bioavailability of Cu for grazing animals and growing plants; this, in turn, reduces Cu availability in the NZ human food chain. Our study is a pilot study to explore associations between Cu and TAA. We measured Cu levels in aneurysmal aortic tissues in patients undergoing Bentall procedures and non-aneurysmal aortic tissue from coronary artery bypass graft patients. METHODS: Aortic samples were collected from 2 groups of patients during elective open-heart surgery over 4 months between November 2017 and February 2018. The groups were a TAA group, patients with non-syndromic aortic aneurysm and without the bicuspid aortic valve or known infectious or inflammatory condition (ANEURYSM; n = 13), and a control coronary artery bypass graft group (CONTROL; n = 44). Standardized digested dry tissue weighed samples were analysed from both groups. Tissue extraction of trace elements was carried out using HCl-H2O2 digestion and a highly sensitive analytical technique, inductively coupled plasma mass spectrometry-used to measure elemental concentrations. RESULTS: Cu concentration (mean ± SD) was significantly lower in ANEURYSM (3.34 ± 0.16 µg/g) when compared to the CONTROL group tissues (4.33 ± 0.20 µg/g) (dry weight; mean ± SD; Student's t-test, P < 0.05). Over 46% of the Aneurysm patients were Maori and live in a geographically Cu-deficient NZ territory. CONCLUSIONS: Cu deficiency may play a role in the development or progression of non-syndromic ascending aortic aneurysms in NZ. Maori patients are more at risk as they commonly live in rural NZ, dependent on locally grown nutritional sources. Further studies are required to confirm this exciting finding and to establish cause and effect relationship.
