title: Improving the alignment of dynamic sheet-formed mats by changing nozzle geometry and their reinforcement of polypropylene matrix composites

authors: Sunny, Tom

abstract: The main objective of this study was to improve the orientation of fibres within the mats produced using dynamic sheet forming (DSF). DSF is used to make fibre mats by forcing a fibre suspension through a nozzle onto a rotating drum. In this research, the effect of nozzle geometry on the orientation of hemp fibres within DSF mats was investigated. The orientation of fibres within the mats produced was assessed using ImageJ (OrientationJ) and X-ray diffraction. It was found that, as the contraction ratio of the nozzle increased, the orientation of fibres within the fibre mats increased. It was also found that the composite tensile strength increased with increased fibre orientation.

title: Visitors to Mauritius - Place, Perceptions and Determinants of Repeat Visitation

authors: Prayag, Girish

subjects: Mauritius

abstract: Tourism has long been recognised as a vital element of the economic development and growth of island destinations. This has been no different for the island of Mauritius, whose appeal is predominantly based on a sun, sand and sea product anchored in resort-based experiences. At the maturity stage of its destination life cycle, the island has embarked on product development and market diversification strategies for growth. In this respect, this study investigates cultural differences in image perceptions for the key generating markets of Mauritius and the factors determining repeat visitation. The relationship among several constructs such as destination image, service interactions, place attachment, personal involvement, satisfaction and future behaviour is explored. Understanding these relationships, can possibly improve segmentation, targeting, product development strategies and revisit intentions. Also, the role of interactions by visitors with hotel employees and how these influence other constructs such as place attachment and personal involvement have been of lesser interest to researchers. Therefore, a literature review on these relationships informs the construction of a theoretical model. Adopting a post-positivist stance, the qualitative component of the research focuses on exploring visitors‟ perceptions of image and service interactions using social constructionism. Personal construct theory informed the choice of a convenience sample of 103 visitors. Broad questions were designed within a phenomenological approach to allow participants to narrate their  lived‟ experiences. Thematic analysis was used to analyse the data and supplemented by content analysis using CATPAC to improve credibility of interpretation. The findings revealed that images are linked to motives for choice and in the case of Mauritius, fulfilment of needs for relaxation and escape as well as socialisation and learning determine visitors‟ perceptions. Service interactions are imbued in values such as integrity and respect, mutual understanding and authenticity of display. Place attachment as a latent dimension was related to the affective image of the place while personal involvement and familiarity influenced perceptions of service interactions. Nationality, ethnicity and language spoken had some influence on perceptions.
These findings informed the design of a survey instrument that was administered to a quota sample of 1000 visitors, of which, 705 were useable. The method of data collection
iii
was self- completion by hotel guests and self-completion in the presence of the researcher on beaches around hotels. Exploratory factor analysis was initially used to assess the dimensionality of the various constructs in the theoretical model, thereafter confirmatory factor analysis and structural equations modelling were undertaken to validate the model. Cluster analysis was used to identify different segments of visitors based on their level of personal involvement and place attachment. Regression models were developed to predict visitors overall image, satisfaction and loyalty as well as their propensity to be repeaters. The results indicated that destination image has both direct and an indirect influence over future behaviour. In particular, personal involvement and perceived service interactions are antecedents of destination image, while place attachment has motives for choice and personal involvement as antecedents. Given these relationships, important implications for destination image, product development as well as direction for destination marketing are offered. Implications for service providers are discussed and theoretical contributions of the study are highlighted.

title: Real world initiation of newly funded empagliflozin and dulaglutide under special authority for patients with type 2 diabetes in New Zealand

authors: Chepulis, Lynne Merran

subjects: GLP1RA

abstract: Background: Type 2 diabetes (T2D) is sub-optimally managed for many in Aotearoa New Zealand, and disproportionately affects Māori and Pacific peoples. In February 2021, SGLT2i/GLP1RA agents were funded for use for the first time with prioritisation for Māori, Pacific and those with cardiovascular and/or renal disease or risk (CVRD). This study evaluates the impact of health system factors on initiation of SGLT2i/GLP1RA therapy. 

Methods: Primary care data was collected for patients with T2D aged 18–75 years from four primary care organisations (302 general practices) in the Auckland / Waikato region of New Zealand (Feb 2021 – July 2022). Initiation of SGLT2i/GLP1RA therapy was reviewed by patient (age, gender, ethnicity, CVRD status) and health system variables (funding, provider type, staffing, patient numbers, rurality, after-hours access). Logistic regression was used to estimate the odds ratio of a patient being dispensed SGLT2i/GLP1RA. 

Results: Of 57,743 patients with T2D, 22,331 were eligible for funded SGLT2i/GLP1RA access and 10,272 of those (46.0%) were prescribed. Initiation of therapy was highest in Māori (50.8%) and Pacific (48.8%) patients (vs. 36·2–40·7% of other ethnic groups; P < 0.001), but was comparable in those with and without CVRD (47·1% vs. 48·9%; P = 0.2). Prescribing was highest in practices with higher doctor/patient numbers, low-cost fees, Māori health providers and clinics without after-hours access.

Conclusion: Prioritised access for SGLT2i/GLP1RA appears to be associated with a reduced health equity gap for Māori and Pacific patients with T2D in NZ, but work is required to improve prescribing for patients with CVRD.
