“After getting the courage to go…” : an interpretative phenomenological analysis of the customer experience of people who stop going to therapy : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Psychology at Massey University, Auckland, New Zealand
(Massey University, 2023) Broadhurst, Sara
Objectives: The study investigated the customer experience of people who had chosen to stop going to therapy, after one to three sessions of 50-60 minutes. In addition, it sought to understand if this experience influenced their future likelihood of using therapy and what they would recommend to others about therapy. Design: Qualitative interview study. Methods: Six people participated in semi-structured interviews, of between 60 and 90 minutes, about their customer experience of therapy with a psychologist or counsellor in Aotearoa New Zealand, who stopped after one to three sessions. The qualitative experiential methodology of interpretive phenomenological analysis was applied to the interview transcripts. Results: Using the four customer experience stages as a framework, the analysis generated themes and subthemes which provided insight into the customer experience and dropout decisions. First, in the pre-experience stage negative connotations still exist about mental health, although these have improved over time. Second, in the pre-purchase stage, participants were anticipating the therapy experience, with subthemes of process and expectations. Third, in the purchase stage, the details matter. Included are four subthemes: the physical space, customer feelings, therapist in-session behaviours and the termination experience. Finally, in the post-purchase stage, participants remained optimistic about therapy, with the subtheme that participants would recommend therapy to others, but with caveats. The participants’ decision to engage in future therapy or to recommend therapy to others was not influenced by having an unsatisfactory experience. Conclusions: The results of research to date on the causes of client dropout from therapy is broadly inconclusive and there is little research from a qualitative or customer experience perspective. Considering each stage of the customer experience brings a different perspective to the variables that influence dropout. In addition, it provides valuable insight into the customer’s decision to terminate, the things that need to be true for people to participate in future therapy and what they say to others when recommending therapy. This study makes a number of contributions for therapists looking to reduce the dropout rate of people attending their service.
Phenotypic characterisation of members of the Lachnospiraceae family isolated from ruminants : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Microbiology at Massey University, Manawatū, New Zealand
(Massey University, 2023) Rajasekaran, Krsana
Microbial fermentation in the rumen employs the metabolic capacity of microorganisms to degrade lignocellulose from the diets consumed by ruminant animals. Advances in genomic, metagenomic and culture independent methods for studying microbiomes have caused a lag in the functional characterisation of isolated cultures. Moreover, understanding the interactions between microbes during rumen fermentation may help in producing strategies to improve animal productivity and address environmental impact issues such as enteric methane emissions. In this study it is demonstrated how cultured strains are required to accurately describe the functional traits of rumen bacteria. Members of the Lachnospiraceae family are one of the most abundant bacterial groups in the rumen, however, many of its isolated members are yet to be fully characterised or properly classified. In this study, the genomes of 45 Lachnospiraceae strains sequenced in the Hungate 1000 project were functionally annotated using the web-based annotation tool, Protologger. These predictions were then compared with phenotypic traits from the corresponding strains, uncovered using microscopy, carbon utilisation testing, and by analyses of short-chain fatty acid production, and headspace hydrogen. The results indicate how the genome can assist in the culturing and studying of rumen microorganisms but should not be solely relied on for the elucidation of functional traits. Phenotypic characterisations of the 45 Lachnospiraceae strains revealed a preference for the resultant soluble components of cellulose degradation rather than hemicellulose. Starch and pectin were more readily fermented in comparison to cellulose and xylan. End product analysis revealed that the studied strains produce acetate, butyrate and propionate, products known to contribute to host health and nutrition. Ethanol, formate, lactate and less commonly succinate were produced as fermentation products demonstrating the potential of the strains to participate in interspecies metabolite transfers. A subset of the strains including members of the genera Lachnospira, Eubacterium and Oribacterium as well as unclassified Lachnospiraceae bacterium strains were shown to produce methanol from pectin degradation. End products of fibrolytic fermentation by the 45 Lachnospiraceae strains can potentially act as substrates for methanogenic archaea. The results of this study help to improve the knowledge surrounding the poorly studied Lachnospiraceae family and increases the overall utility of the Hungate 1000 culture collection. Additionally, the comparison between genotypic predictions and the phenotyping, accentuates the importance of culture-based studies, providing an incentive to continue cultivating representative strains from the rumen environment to clarify how various microorganisms are contributing to rumen fermentation.
Evaluating the accessibility and inclusiveness of community playgrounds for disabled children in Australia : a research report presented in partial fulfilment of the requirements for the degree of Master of Construction in Sustainable Built Environment, School of Built Environment, Massey University, New Zealand
(Massey University, 2023) Glass, Courtney
Play is a significant contributor to the social, physical, emotional, and cognitive development of children. Play is so vital to the wellbeing of children that it is recognised by the United Nations as a fundamental right of childhood. Children with disabilities however, encounter difficulty in realising their right to play. For children with disabilities, playgrounds can perpetuate exclusion and not be places of fun. The existence of barriers to participate in play for children with disabilities is contrary to the United Nations Convention on the Rights of Persons with Disabilities, which recognises that children with disabilities should have equal accesses to participate in play. For children with disabilities an accessible playground provides an environment where there are no physical or environmental barriers to movement, access, and participation. An inclusive playground, however, not only provides an accessible environment, but also allows children regardless of ability to participate equally in play and social experiences without barriers. Physical and social participation is the ultimate goal of an inclusive playground . . . A literature review was conducted to consider what previous evaluations or on-site auditing has been undertaken to evaluate the accessibility and inclusiveness of community playgrounds for disabled children. Upon completion of the literature review, using the New South Wales Government’s Everyone Can Play: Playspace Evaluation Checklist, the accessibility and inclusiveness of community playgrounds for disabled children was assessed at 25 community playgrounds located in the states of Victoria and New South Wales, Australia. The results were used to rank the audited community playgrounds in order of highest overall score to lowest overall score, and to provide a summary of the playgrounds accessible and inclusive features. The results demonstrate a potential relationship between the construction date of the playground and the accessibility and inclusiveness of the playground for disabled children. The older the playground is, the less likely it is to offer an accessible and inclusive environment for disabled children. Playgrounds located in New South Wales were more likely to offer an accessible and inclusive environment for disabled children compared to playgrounds located in Victoria. The findings also indicate that destination playgrounds are likely to feature more accessible and inclusive elements than neighbourhood playgrounds. When comparing the overall amenities scores of destination and neighbourhood playgrounds, destination playgrounds scored higher overall. The results indicate that there is limited correlation between accessible and inclusive playgrounds in areas of socio-economic advantage or disadvantage. Additionally, wayfinding, layout and signage was found to be a significant opportunity for improvement to the accessibility and inclusiveness of community playgrounds for disabled children.
Accessibility of the built environment for vulnerable populations : a research report presented in partial fulfilment of the requirements for the degree of Master of Construction in Quantity Surveying, School of Built Environment, Massey University, New Zealand
(Massey University, 2023) Li, Dongdong
The United Nations Convention on the Rights of Persons with Disabilities states that the disabled have equal rights with other members of society to access the Built Environment (BE). Lots of accessibility legislation has been enacted all over the world to protect the rights of disabilities. But, what about the actual accessibility legislation compliance? It is important to evaluate to what extent the existing buildings have complied with the mandatory legislation, and how far the BE has met the needs of disabled groups to guarantee their equal human rights. This research focuses on manual wheelchair (MWC) users and BE accessibility in New Zealand. There are about 65 million people worldwide who rely on a wheelchair in their daily lives, MWC users make up around 85% of all wheelchair users. And this number is growing. This study will significantly benefit this large amount of population. It will help people more deeply understand their expectations and boost the public to improve BE accessibility and protect MWC users’ rights on the ground . . . A systematic literature review was conducted, and a research gap was identified: there isn’t a study to assess the accessibility legislation compliance of public buildings in NZ, and how well the current BE in NZ meets the MWC users’ needs. To fill this gap, an experiment of 10 case shops in NZ was conducted by measuring their practical dimensions of accessible features and comparing them with the NZ mandatory legislation. The compliance percentages were calculated by shop, by feature, and by sub-item of features. The experiment results were then compared with the findings of the literature review . . . This research will help the public better understand the practical accessibility policies implementation, the main challenges faced by MWC users, underlying causes of poor BE accessibility, and potential ways to improve the situation; it will encourage the government and the public in NZ to remove the existing barriers, address the underlying problems and finally provide an accessible BE for MWC users and protect their equal rights in practice. Other researchers can also use the data of this research, and conduct further investigations based on the findings of this study.
Development of a focused ultrasonic array system for pasture biomass estimation : a thesis presented in fulfilment of the requirements for the degree of Master of Engineering at Massey University, Albany, New Zealand
(Massey University, 2023) Jiang, Zhilin
The ability to accurately measure pasture biomass can significantly impact the profitability of the pasture agriculture industry. One technique that has been used to estimate pasture biomass is to measure pasture height using ultrasonic transducers. It was traditionally achieved using a single ultrasonic transducer with a wide beam angle. Additionally, the previous studies using this method only used the first arrival time of the echo from the top of the grass. However, this can lead to overestimating grass height due to isolated pieces of grass, which may not be directly below the sensor. It does not measure the pasture density. Also, height measurement errors may occur when the sensor is mounted on an agricultural vehicle as the vehicle bounces and tilts. To solve these problems, Legg and Bradley developed a new ultrasonic air-coupled transducer array to estimate the biomass of pastures and achieved good experimental results. However, it was believable that measurement accuracy can be further improved using near field focusing of the transmit and receive arrays. This work describes the development of an ultrasonic array system capable of focusing on the near and far fields for pasture biomass estimation. It extended on the system developed by Legg and Bradley. Angular measurements were made with the array attached to a computer controlled turntable system for different near- and far-field beamforming configurations. It was found that improved beamwidth and dynamic range were obtained when the system focused on the receiver in the near field. Some initial lab measurements were also performed on pasture samples, comparing the effect of using the array's transmit far-field and near-field focusing. The results indicate that focusing the array in the near field improves the performance in detecting the grass, particularly the top, compared with focusing the receiver in the near field and the transmitter in the far field. However, more work is needed, including field trials.
