title: Crystal structure models for the Aldaramide Units of Poly(pentaramides)

authors: Hinton, Michael R.

subjects: crystal structure

abstract: The X-ray crystal structures of seven structurally related diamides, N,N′-dihexyl- and N,N′-dimethylglutaramide, N,N′-dimethylxylaramide, N,N′-dimethyl-l-arabinaramide, N,N′-dimethylribaramide monohydrate, 2,3,4-tri-O-acetyl-N,N′-dimethylxylaramide, and 2,3,4-tri-O-acetyl-N,N′-dimethyl-l-arabinaramide, were determined. These diamides were chosen as solid-state conformational models for the diamido repeating units of the corresponding polyamides. Solid-state conformations of the two N,N-dialkyglutaramides, with no pendant groups, were compared to those of their stereochemically different trihydroxy derivatives N,N′-dimethylxylaramide, l-arabinaramide and ribaramide, and the two aforementioned tri-O-acetylpentaramides.

title: Investigating Strategies to Support Reverse-Engineering of Interactive Systems

authors: Alsharif, Aman

subjects: Reverse-Engineering

abstract: Most software applications today provide a graphical user interface (GUI), which facilitates the use of the software by offering graphical and visual elements to the users. The correctness of the user interface is fundamental to the correct implementation of the overall software. Using reverse engineering tools and methods is one of the most efficient ways to understand a system, and to assess its functionality and usability. However, traditional reverse engineering methods are not well suited to interactive elements of a system. This research examines and analyzes reverse engineering techniques of interactive systems written in the Java programming language, with the aim of creating a set of models of the entire system namely, Presentation Models (PModels) and Presentation Interaction Models (PIMs), which are very effective in describing structural and functional behavioral features of the interactive system. This study will also highlight some of the problems that exist in this domain and investigate several possibilities for improving the process.

title: The environmental and social impact of Kaivolution's services

authors: Paymani, Kesian Serous

subjects: food insecurity

abstract: Food insecurity and food waste are two significant issues within New Zealand. In order to address these two issues organisations like Kaivolution rescue and redistribute food to community groups who help those in need. Kaivolution rescues edible food from food retailers that would otherwise be thrown away, and redistributes this rescued food to community groups who assist whanau who are food insecure. The purpose of this thesis is to examine the social and environmental impact of Kaivolution’s food redistribution service. Three of Kaivolution’s stakeholders were chosen to participate; Kaivolution volunteers, community groups who receive the rescued food, and whanau who receive the food from the community groups. Semi-structured interviews were used in order to gather data. The key findings showed that for Kaivolution volunteers there was an increase in awareness of social issues like poverty, food insecurity, and homelessness. The findings also showed that the participants volunteering with Kaivolution had increased feelings of belonging, and increased social networks, both contributing to a heightened sense of wellbeing. The key findings from both the community groups and the whanau had significant overlap. Key findings from these participants illustrated how the process of colonisation has negatively impacted Māori who are more prone to food insecurity within Aotearoa. Other groups vulnerable to food insecurity included university students and children from various ethnicities. The findings also highlight the failings of our current social welfare system to provide enough resources for basic living. Community groups often step in to assist food insecure whanau in a culturally and social sensitive community approach to food redistribution. Such an approach promotes a sense of community, builds social relationships, and enhances whanau sense of self-worth and belonging.
