title: Event-based applications and enabling technologies

authors: Hinze, Annika

subjects: computer science

abstract: Event processing has become the paradigm of choice in many monitoring and reactive applications. However, the understanding of events, their composition and level of abstraction, the style of processing and the quality of service requirements vary drastically across application domains. We introduce the basic notions of event processing to create a common understanding, present the enabling technologies that are used for the implementation of event-based systems, survey a wide range of applications identifying their main features, and discuss open research issues.

title: Harry Kenrick: the first warden of the Te Aroha mining district

authors: Hart, Philip

abstract: Because of his improvident father, Harry Kenrick left England for the Victorian goldfields before moving to the South Island of New Zealand. In 1865, he settled in the West Coast to begin a lifetime career of working for the government. In addition to his official duties, he was involved in mining and assisted to develop the district, becoming involved in disputes that foreshadowed his experiences at Thames.
Appointed as resident magistrate for Poverty Bay in 1877, his work was praised, as it had been on the West Coast, but two years later he was abruptly moved to Thames to become both magistrate and warden after the forced resignation of his predecessor, William Fraser. The latter’s career is examined, as is how his clique hated Kenrick for replacing him; but most residents welcomed a man whose decisions were seen as fair and just. Fraser retained support amongst many in the community, becoming mayor and then a member of parliament, but continued to snipe at Kenrick, supported by a small number of malcontents, who made his life difficult.
In his determination to make his subordinates perform their duties satisfactorily, Kenrick provoked conflict with Hugh McIlhone, Inspector of Miners’ Rights, and James Monteith McLaren, Inspector of Mines. They were supported by two prominent Thames residents, Louis Ehrenfried, a brewer and local government politician, and George Nathaniel Brassey, a solicitor, who spent years trying to undermine Kenrick for their own personal advantage. In 1880 and 1885, two petitions to remove him failed miserably, as his reputation both locally and with the government and its officials had risen steadily. 
Kenrick improved mining regulations and enforced them fairly, as even some who lost cases accepted. At Te Aroha, after some initial criticisms he became popular because of his efforts to be fair to all who came before him in court and his assistance both to mining and to the development of the district. His efforts to assist Maori made him popular with them as well, and when he died, prematurely, he was deeply mourned by both Maori and Pakeha.

title: Merea Wikiriwhi and George Thomas Wilkinson

authors: Hart, Philip

abstract: Merea Wikiriwhi was one of the few women to invest in Te Aroha mining. Her life has been traced in as much detail as can be found because so little has survived about the lives of Maori women. As George Thomas Wilkinson’s surviving diaries reveal his importance in her life, his story was included as well, concentrating on his personal life rather than his official career. 
Merea was a member of several Ohinemuri hapu, with links through whakapapa to some of their more senior rangatira. Mostly living at or near Waitoki, between Paeroa and Te Aroha, she lived a frugal life, not wasting the income she received from land sales. These sales first required her to insist on her rights both in the land court and in a convoluted legal battle over a will signed in her favour by a distant relative. Over time, she would sell most of her land, but never became entirely landless. She invested in only one mining claim, but in the 1930s joined others to claim that the government was not paying them goldfields revenue for land they had sold.
George Thomas Wilkinson entered her life in 1880, when he was the ‘native agent’ in Hauraki. Despite having fought against Maori and nearly being killed, his surviving diaries reveal that he lived in the manner of a Pakeha Maori with three Maori women (simultaneously for a time), having children both by Merea and the woman he would eventually marry. Wilkinson had close friendships with many Maori and Pakeha Maori, and his genuine regard for them is reflected not only in his attempting, in his official capacity, to be fair to their interests – even as he assisted the government to separate them from their land – but in particular by his affection for a young girl, Wairingiringi, who shared his house in Thames. Although he and Merea would part, he tried to ensure that her children, like all his children, would do well in a Pakeha world.
