title: Binding data mining and expert knowledge for one-day-ahead prediction of hourly global solar radiation

authors: del Campo-Ávila, José

subjects: computer science

abstract: A new methodology to predict one-day-ahead hourly solar global radiation is proposed in this paper. This information is very useful to address many real problems; for instance, energy-market decision making is one of the contexts where that information is essential to ensure the correct integration of grid-connected photovoltaic solar systems. The developed methodology is based on the contribution of different experts to obtain improved data-driven models when included in the data mining process. The modelling phase, when models are induced and new patterns can be identified, is the one that most benefits from that expert knowledge. In this case, it is achieved by combining clustering, regression and classification methods that exploit meteorological data (directly measured or predicted by weather services). The developed models have been embedded in a prediction system that offers reliable forecasts on next-day hourly global solar radiation. As a result of the automatic learning process including the knowledge of different experts, 14 different types of day were identified based on the shape of hourly solar radiation throughout a day. The conventional definitions of types of days, that usually consider 4 options, are updated with this new proposal. The next-day prediction of hourly global radiation is obtained in two phases: in the first one, the next-day type is obtained from among the 14 possible types of day; in the second one, values of hourly global radiation are obtained using the centroid of the predicted type of day and extraterrestrial solar radiation. The relative root mean square error of the prediction model is less than 20%, meaning a significant reduction compared to previous models. Moreover, the proposed models can be recognized in the context of eXplainable Artificial Intelligence.

title: Book Review Essay: Reimagining the subject of feminism: Six women artists

authors: Middleton, Sue

abstract: Maria Tamboukou is a Reader in Sociology and Co-Director of the Centre of Narrative Research at the University of East London,  UK. A trans-disciplinary feminist writer, Tamboukou is known for imaginative conceptual assemblages in the study of narrative texts. Influenced by Hannah Arendt and Adriana Cavarero, she argues: “narratives foreground the question of Who one is, as differentiated from the Western (male) philosophical tradition that has revolved around the question of What one is” (Tamboukou, 2010a: 13). “Who” one is, however, is never fixed, never stable, always in process – in Deleuzian terms, nomadic. Citing Rosi Braidotti, (Tamboukou 2010a: 84) defines nomadic subjects as always in transition, characterised not by homelessness but by “their ability to create their homes everywhere” in the process of becoming.

title: Te kura o Ruatoki 1896 - 1979

authors: Williams, Kim Reina Reremoana

subjects: Ruatoki Native School

abstract: Ko tēnei tuhinga roa e kōrero ana mō te Kura o Ruatoki i roto i te rohe o te iwi o Tūhoe. I whakatūria he kura i te tau 1896 i runga i te inoi a ngā Koroua ki te Kāwanatanga o taua wā.
Hai te Upoko tuatahi, ka whakatakotoria ngā kōrero mō te āhua o te whenua, ngā tāngata me ā rātau nekeneke. Tutū ana te puehu i runga i ngā whakatū waewae ki te iwi, ki te Pākehā hoki mō taua whenua.
Hai te Upoko tuarua ka takoto ngā kōrero mō te heke o ngā pānui o ngā inoi, ngā reta a ngā Koroua ki te Kāwanatanga mō te whakatū i tētahi Kura i Ruatoki. Te nuinga o ēnei rauemi i rangahaua, i kitea, i te Whare pukapuka o Pōneke. Ko ētahi i te Whare pukapuka o Tāmaki. Ka tau te tono, ka kitea te tūtukitanga o te ao Pākehā ki te ao Māori, otirā, kua puta te kaupapa i whakatūria ake ai te kura hei whakatangata whenua i ngā tāngata, i ngā aronga hinengaro Māori kia rite ki tō te Pākehā.
Hai te Upoko tuatoru ka tirohia ko ngā tuhinga a ngā Tumuaki mai i te tau 1896 ki te tau 1979 mō te Kura o Ruatoki. Ka kite i roto i ā rātau tirohanga te āhua o tā rātau kaihautū i te rerenga o te kaupapa nei. Ko ngā kaihautū i te waka nei, he tūmau noa nā te Kāwanatanga hai whakatō i te Pākehātanga ki roto i te whatumanawa Māori.
He tini o te whārua i hinga i roto i ēnei tau i runga i ngā mate urutī, mate tauhou i pā ki roto i te whārua. Ahakoa tērā ka tukuna tonu ngā tamariki ki te kura i runga i te whakapono he oranga ka puta mai i reira. I te tau 1946 ka tū he kura tuarua, he Māori District High School. Ko te nuinga o ngā tamariki o Tawera rāua ko Ruatoki i haere mai ki tēnei kura. Tokoiti ia tau i whiwhi karahipi mō te haere ki ngā kura hāhi o Tīpene rāua ko Wikitōria. Tērā pea he tango atu i ēnei tamariki mai i ngā āhuatanga Māori o te whārua.
Hai te upoko tuawhā, ka whakakorehia te kura tuarua. Ko ngā take mō te katinga ka āta whakamāramahia. He mahi nanakia nā te tari Mātauranga me āna āpiha i runga i ngā nekeneke mō tēnei kaupapa.
Hai te Upoko tuarima ka whakarerekēhia ngā marautanga ako kia tau ko te kaupapa ako i roto i ngā reo e rua ki roto i te kura. He whakautu tēnei i te kōrero a Richard Benton o te N.Z.C.E.R e kī ana, "Kāore e roa ka ngaro te reo Māori." Koinei te wā i whakapihihia ake ai te kaupapa ako i roto i ngā reo e rua, ā, ka tiritiria ko te kaupapa Rumaki Reo.
Hai te Upoko tuaono ko te kōhuretanga o te kaupapa Māori me te puāwaitanga o ngā hinengaro me ngā wairua o ngā tamariki ki te āhua o te ako i ā rātau mahi i roto i tō rātau ake reo. I tīmatahia te kaupapa i te tau 1977. Tae rawa atu ki ngā tau o muri mai kua kitea kē te huringa o ngā ngākau ki te ako.
Hai te Upoko tuawhitu ka whakaatahia mai ngā whakanekeneke i raro i tēnei kaupapa. He nui ngā tutukitanga ki ngā ture i te whakatūtanga o ngā Kura mō Āpōpō.
Hei whakarāpopototanga i ngā moemoeā me ngā tūmanako ka titiro ake ki ngā waru tekau tau kua pahemo. Kua turuki ki te pō, ki te ao. Kua noho te pukenga o te kupu kōrero, kua taipū ngā kaupapa. Ko taku mahi he whakarārangi i ngā pikinga i ngā hekenga i ngā āhuatanga katoa i mahia i roto i tēnei kura mai kore ka kitea atu he māramatanga he huarahi rānei e tiketike ake ai ngā mahi ako, ngā akoranga, ki ēnei o ā tātau mokopuna o Ngāi Tūhoe e tipu mai nei. Nō reira ka hoki rawa ngā kauhau ki ērā i whakatakotohia mai e ngā mātua tīpuna. Ka tīkina atu te kōrero i reira hai whakatinana i ngā tūmanako mō te wharekura o Ruatoki i tēnei wā.
