Item Restricted Packaging, perception, and acceptability: A comprehensive exploration of extrinsic attributes and consumer behaviours in novel food product systems(Wiley on behalf of Institute of Food Science and Technology, 2024-01)In today's global markets, the constant arrival of new products represents a challenge for the food industry to offer distinct choices to consumers, primarily due to the parallel sensory attributes and pricing structures of the available food options. Innovators must employ methodologies beyond traditional sensory analysis to ensure the product's success. Researchers must, therefore, explore the entire product experience to understand its influence on consumer behaviours. Food choices are multifaceted, influenced by various factors, including individual physiological and psychological characteristics and intrinsic and extrinsic product attributes. As a result, consumers' decisions are shaped by the multisensory information derived from products they encounter in supermarkets. This review aims to comprehensively examine the factors influencing consumer food choices, from initial product encounters to consumption. The review explores the impact of repetitive tasting on the consumer's attitudes and intentions towards novel products. Additionally, the review investigates which extrinsic attributes capture consumer attention in supermarket settings. It also delves into the effects of extrinsic product attributes on both explicit and implicit emotions and expectations raised about the sensory properties of the product and, ultimately, their purchasing behaviours.Item Restricted Maternal obesity modulates expression of Satb2 in hypothalamic VMN of female offspring(Multidisciplinary Digital Publishing Institute (MDPI), 2020-04)Maternal obesity during pregnancy is associated with a greater risk of poor health outcomes in offspring, including obesity, metabolic disorders, and anxiety, however the incidence of these diseases differs for males and females. Similarly, animal models of maternal obesity have reported sex differences in offspring, for both metabolic outcomes and anxiety-like behaviors. The ventromedial nucleus of the hypothalamus (VMN) is a brain region known to be involved in the regulation of both metabolism and anxiety, and is well documented to be sexually dimorphic. As the VMN is largely composed of glutamatergic neurons, which are important for its functions in modulating metabolism and anxiety, we hypothesized that maternal obesity may alter the number of glutamatergic neurons in the offspring VMN. We used a mouse model of a maternal high-fat diet (mHFD), to examine mRNA expression of the glutamatergic neuronal marker Satb2 in the mediobasal hypothalamus of control and mHFD offspring at GD17.5. We found sex differences in Satb2 expression, with mHFD-induced upregulation of Satb2 mRNA in the mediobasal hypothalamus of female offspring, compared to controls, but not males. Using immunohistochemistry, we found an increase in the number of SATB2-positive cells in female mHFD offspring VMN, compared to controls, which was localized to the rostral region of the nucleus. These data provide evidence that maternal nutrition during gestation alters the developing VMN, possibly increasing its glutamatergic drive of offspring in a sex-specific manner, which may contribute to sexual dimorphism in offspring health outcomes later in life.Publication Open Access Notes for plant collections(Lincoln College. Plant Science Department, 1984)Students of Botany and Plant Sciences are often required to make collections of plants. These may be native plants, plants of agricultural or horticultural importance, or plants of botanical interest. Such collections are usually part of the practical requirement of the courses. They: (1) Give an aid to learning common native, crop, pasture and horticultural plants. (2) Give experience in the use of plant identification keys (3) Give a knowledge of how to prepare specimens for submission to a qualified botanists when the collector is unable to identify the plant. (4) Give an indication of the methods involved in building up of large reference collections. An herbarium is a collection of plants preserved for study. It is an aid to the identification of subsequent collections. To be useful specimens in plant collections must be carefully selected, properly prepared and accompanied by adequate data. Vascular plants (ferns, gymnosperms and flowering plants) are most easily preserved by pressing and mounting on card. Pressed specimens may be supplemented by drying and/or pickling material in a suitable liquid medium. e.g pine cones are impossible to press, but keep well in the dried form. Fleshy fruits are best pickled in a suitable liquid.Item Restricted Do capital markets reward corporate climate change actions? Evidence from the cost of debt(Wiley-Blackwell, 2023-09)As a result of recurring natural disasters caused by climate change, firms are under enormous pressure to reconsider their environmental footprints. However, whether or not investors reward firms' climate change actions remains a topic of considerable debate. Using a sample of S&P 500 companies over the period 2005–2020, we hypothesise and find a significant negative relationship between climate change actions and the cost of debt, indicating that investors indeed reward corporate climate efforts in the form of lower cost funds. This relationship exists in both environmentally sensitive and non‐sensitive industries and remains negative and statistically significant even after controlling for the impact of the ongoing pandemic (COVID‐19). The findings are robust to the use of alternative measures for our variables, alternative estimation methods and after controlling for endogeneity issues. We interpret our findings within the decision‐usefulness and stakeholder‐agency theories that suggest that non‐financial information on firms' environmental performance is becoming increasingly important when borrowers' creditworthiness is assessed. Our study offers important regulatory and academic policy implications.Item Open Access Māori values and agricultural value chains(2023)Presentation given at Research-Policy Nexus Workshop : Nutrition for ALL: What can we learn from communities in Mountain and Hill Region?
