title: Efficient Process Model Discovery Using Maximal Pattern Mining

authors: Liesaputra, Veronica

subjects: Science & Technology

abstract: In recent years, process mining has become one of the most important and promising areas of research in the field of business process management as it helps businesses understand, analyze, and improve their business processes. In particular, several proposed techniques and algorithms have been proposed to discover and construct process models from workflow execution logs (i.e., event logs). With the existing techniques, mined models can be built based on analyzing the relationship between any two events seen in event logs. Being restricted by that, they can only handle special cases of routing constructs and often produce unsound models that do not cover all of the traces seen in the log. In this paper, we propose a novel technique for process discovery using Maximal Pattern Mining (MPM) where we construct patterns based on the whole sequence of events seen on the traces—ensuring the soundness of the mined models. Our MPM technique can handle loops (of any length), duplicate tasks, non-free choice constructs, and long distance dependencies. Our evaluation shows that it consistently achieves better precision, replay fitness and efficiency than the existing techniques.

title: ‘Home is where the heart is broken?’: Examining the impact of intimate relationship challenges on meanings of home

authors: Smith, Paula Ngaire

subjects: home

abstract: This thesis makes an original contribution to emotional and material geographies by addressing the ways in which mutually constituted meanings of home and identity change in the wake of intimate, coupled relationship disruption. It examines practices of home making, unmaking and remaking of ten (nine women and one man) heterosexual individuals who have experienced relationship challenges and have homes the Waikato region of Aotearoa New Zealand. Three methods of data collection - semi-structured interviews; home visits; and, solicited and unsolicited diaries - were used to access the emotional and spatial experiences of this group of people.
Feminist, queer and poststructuralist geographical theories are used to analyse the connection between relationships, emotions and materialities of home spaces. My findings are organised into two related themes: materialities and emotions. The first theme - materialities – foregrounds the role of objects for making, unmaking and remaking home and heterosexual couples. Following objects in and out of couple’s homes highlights gendered power relations and the importance of intergenerational relationships. Individual power, as well as the power of objects, is examined, with attention paid to how power and coupledom can be subverted or queered. The second theme – emotions – allows for an understanding of care, love, guilt and shame across the scales of bodies, objects, and homes. Emotions and affect are ‘sticky’ in that they attach to objects and pass between bodies and homes. Physical violence enacted on the home, as well as emotional or financial abusive behaviour within the home, are considered. I also discuss home as a place of healing and recovery. 
It is hoped that this examination of heterosexual couple relationship breakdown and home disruptions will encourage more critical understandings of geographies of identities, home, materialities and emotions.

title: /u/ fronting and /t/ aspiration in Māori and New Zealand English

authors: Maclagan, Margaret

subjects: Maori

abstract: This article examines the relationship between the frontness of /u/ and the aspiration of /t/ in both Māori and New Zealand English (NZE). In both languages, these processes can be observed since the earliest recordings dating from the latter part of the nineteenth century. We report analyses of these developments for three groups of male speakers of Māori spanning the twentieth century. We compare the Māori analyses with analyses of related features of the speakers' English and of the English of monolingual contemporaries. The occurrence of these processes in Māori cannot be seen simply as interference from NZE as the Māori-speaking population became increasingly bilingual. We conclude that it was the arrival of English with its contrast between aspirated and unaspirated plosives, rather than direct borrowing, that was the trigger for the fronting of the hitherto stable back Māori /u/ vowel together with increased aspiration of /t/ before both /i/ and /u/.
