title: Influence of nitrogen on the primary and secondary metabolism and synthesis of flavonoids in Chrysanthemum morifolium Ramat

authors: Liu, Wei

subjects: Chrysanthemum moriforlium Ramat

abstract: The effects of nitrogen (N) supply on nitrogen metabolism in leaves of Chrysanthemum morifolium Ramat. were examined in five different stages throughout the growing season. The results suggested that flavonoids content was positively related to phenylalanine ammonia-lyase activity through the whole growing stage of the plant but with a decreasing correlation coefficient for increasing nitrogen supply. There was no correlation between flavonoids and 4-coumarate coenzyme A ligase. Soluble protein content was positively correlated with phenylalanine ammonia-lyase activity because there was little competition for the phenylalanine in the leaves under low nitrogen supply. Phenylalanine ammonia-lyase activity decreased gradually with increasing nitrogen supply because of the competition for the phenylalanine in protein synthesizes. The results suggest that nitrogen nutrition plays a key role in biosynthesis of enzymes in the leaves of C. morifolium.

title: High-risk victims of intimate partner violence within the Integrated Safety Response pilot: An examination of psychosocial stressors and repeat victimisation

authors: Tomkins, Jordan

abstract: Intimate partner violence (IPV) is a serious social issue in Aotearoa New Zealand, especially for victims at high risk of experiencing ongoing harm–or even death–as a result of IPV. Yet there is relatively limited empirical research that quantifies the stressors faced by high-risk victims, nor investigates whether these factors predict IPV recurrence. Using Dutton’s (2006) nested ecological theory to frame this longitudinal study, we examined 165 high-risk IPV cases from the Integrated Safety Response (ISR) pilot. With a primary focus on victims, we manually coded 39 baseline variables across the individual, relationship and community ecological levels; recorded initial engagement with ISR interventions; and examined IPV recurrence reported to police during the 12-month follow up. Results demonstrated that extensive stressors were experienced by these victims and that most victims had at least one IPV recurrence reported to police during follow up. Whilst only a modest number of variables significantly predicted IPV recurrence, physical IPV recurrence or offence detection; we identified that nonfatal strangulation, victim fear, relationship status and the victim’s initial engagement with ISR interventions all uniquely predicted these outcome measures across multivariate analyses. Theoretically, we found empirical support for Dutton’s (2006) nested ecological framework, although the explanatory mechanisms for the four key predictors need to be examined in future research. Practically, improved awareness of high-risk victims’ needs can guide collaborative support responses and, among a group with several possible risk factors, identifying predictors of repeat victimisation can inform risk assessments and prevention strategies for high-risk IPV cases. Finally, we consider limitations of the current research and make several important recommendations for future research.

title: Kaumātua mana motuhake: Kaumātua managing life-transitions through tuakana-teina/peer-education

authors: Hokowhitu, Brendan

abstract: People face signifi cant transition points as they age, such as loss of independent living, loss of a spouse and changing health conditions. Successfully navigating these transitions depends on being able to manage emotional and socio-economic factors, as well as service systems, while often being reliant on family or whānau. Historically however, kaumātua have faced a dominant society that has failed to realise their full potential as they age. Yet, for Māori, kaumātua are “carriers of culture, anchors for families, models for lifestyle, bridges to the future, guardians of heritage and role models for younger generations.” Kaumātua mana motuhake is invested in upholding kaumātua tino rangatiratanga (independence and autonomy) via high-quality Māori research that will lead to better life outcomes for kaumātua and their whā nau.
