title: Analysing Reverse Engineering Techniques for Interactive Systems

authors: Lin, Feifei (Amy)

subjects: Reverse engineering techniques

abstract: Reverse engineering is the process of discovering a model of a software system by analyzing its structure and functions. Reverse engineering techniques applied to interactive software applications (e.g. applications with user interfaces (UIs)) are very important and significant, as they can help engineers to detect defects in the software and then improve or complete them. There are several approaches, and many different tools, which are able to reverse-engineer software applications into formal models. These can be classified into two main types: dynamic tools and static tools. Dynamic tools interact with the application to find out the run-time behaviours of the software, simulating the actions of a user to explore the system’s state space, whereas static tools focus on static structure and architecture by analysing the code and documents. Reverse engineering techniques are not common for interactive software systems, but nowadays more and more organizations recognize the importance of interactive systems, as the trend in software used in computers is for applications with graphical user interfaces. This has in turn led to a developing interest in reverse engineering tools for such systems. 

Many reverse engineering tools generate very big models which make analysis slow and resource intensive. The reason for this is the large amount of information that is generated by the existing reverse engineering techniques. Slicing is one possible technique which helps with reducing un-necessary information for building models of software systems. This project focuses on static analysis and slicing, and considers how they can aid reverse engineering techniques for interactive systems, particularly with respect to the generation of a particular set of models, Presentation Models (PModels) and Presentation Interaction Models (PIMs).

title: Preferences for Early Retirement: The Role of Work Related Factors

authors: Fowlie, Toni Jessica

subjects: early retirment

abstract: This study investigated the work related factors related to the retirement preferences of 132 full time older workers, defined as those aged 55+, in a range of New Zealand organisations. This research is important as due to the ageing population, maintaining the employability of the older worker for as long as possible is vital for economic growth and sustainability. Identifying the work related factors that may be influencing the early retirement preferences of older workers may lead to a better understanding of ways to maintain these workers in employment. The aim of this study was to contribute to the understanding of the factors which can be influenced directly by organisations, as retirement preferences are strongly influenced by norms and attitudes within the workplace.
The research proposed that the predictor variables perceived age discrimination, job flexibility satisfaction, attitudes towards information and communication technologies (ICTs), perceptions of techno-complexity, and perceived threat from organisational downsizing, would have a direct relationship with early retirement preferences. In this study, the older worker was considered to have early retirement preferences if their preferred retirement age was earlier than their expected retirement age. The model predicted that job satisfaction and job security would mediate the relationships between the predictor variables and early retirement preferences.
Correlation and mediation analyses were performed in SPSS to test the proposed hypotheses. Several hypotheses were supported: perceived age discrimination was positively related to early retirement preferences; perceived age discrimination was negatively related to job satisfaction; job flexibility satisfaction was positively related to job satisfaction; perceived threat from organisational downsizing was negatively related to job security; job satisfaction was negatively related to early retirement preferences; and job security was negatively related to early retirement preferences. The other hypotheses were not supported. This may be due to external factors not explored in this study potentially influencing the retirement intentions of older workers more heavily than the work related factors studied.
Non-hypothesized significant relationships were also found. Firstly, perceived age discrimination was significantly related to job flexibility satisfaction, job security, and perceived threat from organisational downsizing. Job satisfaction and job security were also found to be significantly related to perceived threat from organisational downsizing. These results indicate that the work related factors thought to predict early retirement intentions, are perhaps not currently as important to New Zealand employees as past research has shown, as none of the predictor variables except perceived age discrimination correlated significantly with early retirement preferences. Overall, the results indicate that there are likely to be other factors not explored in this study influencing the retirement intentions of older workers in New Zealand organisations.
For organisations who have recently been through organisational downsizing, employers should be mindful of the negative impacts this can have on older workers, namely job security and job satisfaction. New Zealand organisations should strive to create working environments that take into consideration the needs of older workers, and which encourage older workers to want to stay working, even past the age they are eligible for New Zealand Superannuation. Older workers who feel as though they have limited choice when it comes to making decisions surrounding their retirement may have difficulty adjusting to post-retirement life, thus organisations should be doing all they can to encourage flexible transitions to retirement

title: Upsetting Geographies: Sacred Spaces of Matata

authors: Brown, Keri Aroha Michelle

subjects: sacred

abstract: My research focuses on the emotional experience of the unearthing of ancestral bones for local Māori of Matata. The coastal town of Matata in the Eastern Bay of Plenty provides a central case study location as it is a town that is facing the pressure of coastal residential development as well the added strain of dealing with the 2005 flood which has compounded issues over local waahi tapu.  Local iwi have continued to actively advocate for the protection of these sites especially with regard to the ongoing discovery of ancestral bones.

Cultural and emotional geographies provide the theoretical framework for this research. This framework has been particularly useful as it encourages reflexive commentary and alternative ways of approaching and thinking about, and understanding knowledge. I have incorporated the research paradigm of kaupapa Māori which complements my theoretical framework by producing a research design that is organised and shaped according to tikanga Māori while (in) advertently critiquing and challenging traditional ways of conducting research. The overall aim is to explore the current issues surrounding the discovery of ancestral bones through korero with local iwi members. It is through their perspectives, stories, beliefs and opinions that provide a better understanding of the meanings attributed to waahi tapu and the influence of certain events such as the 2005 flood. I examine, critically the relationship between power, sacred sites, bones and the body. 

It is from these objectives that I contribute to an area of scholarship that has been largely left out from geographical enquiry. I suggest that the importance of sacredness and spirituality has been relatively overlooked as an influential factor in people's perceptions of the world around them. This thesis is intended to demonstrate the value of indigenous perspectives of bones, the body and sacredness as a way of better understanding some of the complexities that can arise when cross-cultural approaches collide in environmental planning.  

There are three main themes that have emerged from this research. The first theme has to do with competing knowledges. To Māori, the location and knowledge of ancestral bones is culturally important and is in its self sacred, therefore certain tikanga is applied as a means of a protection mechanism. However this ideologically clashes with traditional scientific western approaches which are privileged over other alternative ways of understanding knowledge, in this case Māori knowledge. The second related theme concerns the process of boundary making and cross-cultural ways of perceiving 'sacred' and 'everyday' spaces. To better understand these perspectives involves acknowledging the embodied and emotional experience of wāhi tapu to Māori, and the active role of kaitiaki in the protection and careful management of these culturally important spaces.
