title: Does family life help to be a better leader? A closer look at crossover processes from leaders to followers

authors: Ten Brummelhuis, Lieke L.

subjects: family

abstract: Although research on family-to-work processes is accumulating, not many studies have looked at how the leader's family issues spillover to work and what the consequences are for their followers. We investigate whether leaders’ family-to-work conflict (FWC) and enrichment (FWE) influence first their own well-being at work (i.e., job burnout and work engagement) and consequently the well-being of their followers due to crossover processes. We test whether crossover is due to the transfer of emotions from the leader to followers (affective crossover) or due to diminished or enhanced support from the leader (behavioral crossover). Using a sample of 199 leaders and 456 followers, we found that leader FWC (Time 1) was positively related to leader feelings of burnout 4 weeks later (Time 2), consequently enhancing follower feelings of burnout 5 weeks after Time 1 (Time 3). Similarly, leader FWE had a positive relationship with follower engagement, through leader enhanced engagement. Our findings fully supported the affective crossover mechanism. In addition, leader burnout was negatively related to leader supportive behavior, indirectly increasing burnout among followers. Our results underscore that leaders’ family life matters at work, influencing not only their own well-being but also how they motivate and support their followers.

title: Modelling safety properties of interactive medical systems

authors: Reeves, Steve

subjects: computer science

abstract: Formally modelling the software functionality and interactivity of safety-critical devices allows us to prove properties about their behaviours and be certain that they will respond to user interaction correctly. In domains such as medical environments, where many different devices may be used, it is equally important to ensure that all devices used adhere to a set of safety, and other, principles designed for that environment. In this paper we look at modelling important properties of interactive medical devices including safety considerations mandated by their users. We use ProZ for model checking to ensure that properties stated in temporal logic hold, and also to check invariants. In this way we gain confidence that important properties do hold of the device, and that models of particular devices adhere to the properties described.

subjects: Tumuakitanga

abstract: He iwi a Ngāti Hauā nō roto o Tainui waka, ā, ko tōna rohenga kei te rāwhiti o te rohe o Waikato. Mai anō ka mau tonu a Ngāti Hauā ki tōna arikitanga, nō runga i te whakapapa kia kawea te iwi kia puritia e Ngāti Hauā tōna arikitanga me tōna mana motuhake. Ko tā tēnei tuhikura, ko te whakatōmene i te kukuwhatanga o te rangatiratanga o Ngāti Hauā mā ngā pūrākau o ngā ariki tekau, nāna anō i pīkau i te arikitanga o Ngāti Hauā. Ka puritia e rātou te moemoeā o tō rātou tupuna a Tarapīpipi, te Pou whakawahi Kīngi tuatahi. Nā te moemoeā o ngā ariki, o ngā iwi o taua wā ka tū mai a Tarapīpipi ki te whakapou i te Kīngi tuatahi i te tau 1858. Hei whakapūaho i te whakatairitenga o te ao kōhatu o te Māori me te nohonga o te Pākehā ki Aotearoa nei, ka tīmata tēnei rangahau ki te pāpā o Tarapīpipi, ki a Te Waharoa. Ka whakatakina ai i ngā ariki o Ngāti Hauā, ngā uri tākerekere o Te Waharoa. Ko ia pūrākau o tēnā Tumuaki, o tēnā Tumuaki he tirohanga ki ngā piki me ngā heke o ia reanga mai i te tāmitanga o te Māori, ā, he manatu ki te mana o te tino rangatiratanga me kotahitanga. Ko te pakirehua matua o te rangahau e whakautua ai e tēnei tuhikura, koia tēnei: He aha te Tumuakitanga? Ko tāna urupounamu hāpai, he aha ngā pūrākau o tēnā ariki, o tēnā Tumuaki o Ngāti Hauā?

Ngāti Hauā is an iwi (tribe) of the Waikato-Tainui confederation based in the eastern Waikato area. For over 200 years, Ngāti Hauā has maintained the role of ariki, based on whakapapa, to lead the iwi into prosperity. This thesis seeks to explore the evolution of the leadership of Ngāti Hauā through the pūrākau of eleven of its ariki who have carried the chieftainship of Ngāti Hauā since the 19th century. They have all maintained the vision of their ancestor Tarapīpipi, the inaugural Kingmaker. A collective vision of unity, prosperity, and peace by ariki and iwi of that time, culminated in Tarapīpipi crowning the first Māori monarch in 1858. To elucidate the juxtaposition of an ancient Māori world and the settlement of Pākehā in Aotearoa, this research starts with the father of Tarapīpipi, Te Waharoa. It then traces each consecutive ariki of Ngāti Hauā who all are direct descendants of Te Waharoa, through the medium of pūrākau (story). Each story is an insight into the struggles and triumphs of each generation since the colonisation of Aotearoa and is a powerful reminder of self-determination and unity. The principal question this thesis aims to answer is: What is the Tumuakitanga? It’s subsidiary question is, what are the stories of each paramount chief of Ngāti Hauā?
