title: AffectiveTweets: a Weka package for analyzing affect in tweets

authors: Bravo-Marquez, Felipe

subjects: computer science

abstract: AffectiveTweets is a set of programs for analyzing emotion and sentiment of social media messages such as tweets. It is implemented as a package for the Weka machine learning workbench and provides methods for calculating state-of-the-art affect analysis features from tweets that can be fed into machine learning algorithms implemented in Weka. It also implements methods for building affective lexicons and distant supervision methods for training affective models from unlabeled tweets. The package was used by several teams in the shared tasks: EmoInt 2017 and Affect in Tweets SemEval 2018 Task 1.

title: An assessment of endocrine disrupting potential of a New Zealand pulp and paper mill effluent using rainbow trout Oncorhynchus mykiss and mosquitofish Gambusia affinis

authors: Ellis, Rosanne Jane

abstract: I examined the effects of a modern mixed thermo-mechanical pulp/bleached kraft (TMP/BK) mill effluent on potential reproductive-endocrine impacts on two fish species, rainbow trout and mosquitofish using a combined approach of laboratory and on-site mesocosm exposures. Rainbow trout Oncorhynchus mykiss were utilised in a combination of early life stage and juvenile (+1 year) long- and short term exposures. Exposure of rainbow trout eggs to 15% (v/v) effluent until 10.5 months of age had no effect on fertilisation, hatching success, time to hatch, time to swim-up, juvenile mortality rate, growth and development. Juvenile (+1 year) rainbow trout were exposed to secondary treated TMP /BK mill effluent at a range of concentrations from environmentally relevant (10%) to 70% (v/v) in two exposure studies. During both 21- and 56-day exposures to 10% and 30% (v/v) effluent, no statistically significant impacts on spleen weight, liver weight, condition factor, and circulating testosterone and pregnenolone levels were observed. Consequently, vitellogenin induction as well as the expression of the estrogen receptor in juvenile males was not observed in either experiment. Statistically significant differences in spleen and liver size as well as high experimental mortality were observed in the 70% (v/v) effluent 21-day treatment and was linked to an atypically high suspended solids load. Two mosquitofish Gambusia affinis experiments were conducted, both consisted of a 21-day exposure using adult females. The first experiment was a multiple concentration exposure to primary and secondary treated effluents. A statistically significant masculinisation response (gonopodial development) was noted in all effluent treatments. However, secondary treatment of the effluent resulted in a significant decrease in gonopodial development. The second experiment focused on filtered and unfiltered secondary treated effluent at an environmentally relevant concentration (15%). Filtration of the treated effluent resulted in the almost complete elimination of the female masculinisation response. In all experiments, male mating behaviour was observed in the masculinised female mosquitofish. I concluded that a significant species difference regarding sensitivity to reproductive-endocrine modulating compounds occurred following exposure to a mixed TMP/BKM effluent. In addition, the data suggest that the compounds of concern are bound to solid matter within the effluent and these effluents have the potential to exert effects through an androgen-like mode of action.

title: Ka moemoeā o koutou kaumatua...

authors: Whitiaua, Ropitini

subjects: Ruatāhuna

abstract: Founded by the spiritual leader and prophet Te Kooti Te Turuki Arikirangi, the Ringatū faith came into existence in the 1870s during a very turbulent time for Māori. Struggling for survival many Māori tribes and communities accepted the teachings of Te Kooti and the principles of the Ringatū church as a means of maintaining their independence, beliefs and culture. A truly syncretic religion, the Ringatū church combines traditional Māori customs and beliefs with Christian scriptures forming a religious institution that fits within Christian doctrine while maintaining many important Māori philosophies. 
Throughout the latter stages of the 19th century and into the 20th century the Ringatū faith found fertile soil in many regions and grew in popularity and strength. Areas like the Bay of Plenty and sections of the East Coast became strongholds of the church and to this present day the Ringatū faith still functions within these areas. Therefore it is not surprising that Ruatāhuna, a small and isolated community located in the centre of Te Urewera has been part of the Ringatū movement since its inception. This community sheltered Te Kooti while he was being hunted by government forces, and the people became devout followers of the Ringatū faith. Therefore the proficies of Te Kooti and the principles of the church have become central in the identity and cultural practises of Tūhoe and the community of Ruatāhuna. 
For generations the Ringatū church has been the main spiritual institution within Ruatāhuna, with its gatherings being attended by the vast majority of the community. Its influence has permeated throughout every facet of Ruatāhuna life including spirituality, politics, social controls and even cultural practise. However in the past 30 years there has been a significant decline in the influence and popularity of the Ringatū church, and its tenants are now maintained by just a few families. This decline is most evident during the monthly gatherings of the Ringatū community in Ruatāhuna on the 12 of each month, ‘tekau-mā-rua’, where there are now only about 20 regular attendees. 

This thesis explores the Ringatū faith within Ruatāhuna from its origin, its development through the decades and current position. It examines the changing dynamics of the church in recent times in order to understand why its popularity and influence has shifted. Finally this study seeks a path forward for the Ringatū church in a modern world, looking at how the faith can respond to the needs of a new generation and to find a purpose in a new age.
