title: Determining and testing the optimal pure-tone frequency for use in acoustic conditioning of free-ranging common carp (Cyprinus carpio)

authors: Mahoney, Brennan Andrew

subjects: carp

abstract: Pure-tone frequencies of 400, 700, and 1000 Hz were tested to determine which achieved the strongest response when used in conditioning experiments on captive common carp (Cyprinus carpio) for the purpose of determining the most effective frequency to use in conditioning experiments on free-ranging common carp. Captive common carp were shown to have the strongest response to the 400 Hz frequency after training that associated sound with food. Response was quantified as moving into a feeding arena when the sound was broadcast, and all frequencies achieved conditioning within five days. Secondly, the attenuation of the three frequencies were compared in a Waikato lake (Lake Kaituna) containing common carp. The ability to maintain signal strength over distance is necessary for frequencies used in the acoustic conditioning of free-ranging common carp due to the potentially large distances involved. Attenuation of the 400 Hz and 700 Hz pure tone frequencies were not significantly different but were both lower than that of the 1000 Hz frequency. The 400 Hz pure tone frequency was used in subsequent experiments on the acoustic conditioning of free-ranging common carp in Lake Kaituna because of superior performance in acoustic conditioning of captive common carp and low attenuation in a natural water body containing free-ranging common carp,. Thirdly, the 400 Hz pure tone was evaluated for its ability to be associated with food by free-ranging common carp. Capture rates at treatment sites where 400 Hz pure tone was broadcast compared to control sites where no sound was broadcast following a five-day training phase and 24 h of no sound or food, were 2.1 times greater during a three-day capture phase. This study demonstrates the trainability of common carp, a trait that can be used to improve control of wild common carp populations.

title: Barriers and supports to the access of justice as experienced by Pasifika women impacted by domestic violence

authors: Gosche, Jessica

subjects: Pasifika

abstract: Domestic violence is a pervasive social issue in New Zealand with the majority of victims being women and children. 45-60% of Pasifika women are likely to experience violence in their lifetime. Despite the prevalence of domestic violence in Pasifika communities, Pasifika women have low rates of accessing services available to assist them to navigate themselves and their children to safety. My research is focused on identifying the barriers and supports as experienced by Pasifika women when attempting to access protection from their abusers and external agency support to deal with the impacts of abuse. Some identified barriers to accessing justice include lengthy court processes, lack of systemic knowledge, language difficulties, lack of knowledge about cultural differences and domestic violence by front line staff, religious values regarding marriage and the role of women and finding physical environments to be an alienating environment. Through a qualitative research frame, I have explored the impact that domestic violence has on Pasifika women. Interviews with two key informants have assisted me with identifying barriers and supports from a professional perspective. A case study approach with five Pasifika women has provided detailed accounts of their experiences as service users. Given the paucity of research on Pasifika women’s experiences, let alone conducted by a Pasifika woman, my research will contribute new insights with a view towards improving service delivery in the state sector and non-governmental services, ultimately ensuring the victim’s safety is paramount without further compromising identity and wellbeing.

title: Te rima tekau ngahurutanga o Te Whare Wānanga o Waikato

authors: Dixon, Ngahuia

subjects: Tohu mātauranga

abstract: E te Whare Wānanga o Waikato – te tohu o te mātauranga, tēnā koe.  Tēnā koe i roto i tō rima tekau tau ngahurutanga.  Kua pakeke haere koe.  Kua tau atu koe ki tērā kaumātuatanga nō reira me mihi ka tika.  He hōnore nui tēnei mōu ake i te mea nāu te moana o mātauranga i roto o Waikato i tuku kia rere, kia pari, ka rere anō.  He wai marino ēnei i ētehi wā, he rehutai i ētehi atu,  he wā anō ka karekare, ka haruru rānei i te pai o te rere o āu mahi.  Ahakoa ēnei huringa o ngā awa o te wā, kei te rere tonu te moana nei, me ōna pikonga ki uru, ki rāwhiti, ki tonga, ki raki rānei, arā ki ngā pito katoa o te ao.  He mātauranga ēnei i tukuna e koe kia pīoioi i te ao.  Hei aha - hei whakawhānui ki te mātatoru o te tangata, he aha kei ō whare kōrero, hei whakakīkī haere i ā rātou kete mātauranga, ahakoa Māori, tauiwi huri noa.  Koinei ngā korowai mō ngā manu i kai i te mātauranga nāu i rumaki.   Ināianei arā te kōrero:

Nō rātou, nō mātou, nō tātou te ao 

E kore e mimiti ēnei huarahi tautoko āu, - nā mēnā ka tūwhera tonu tō ngākau ki ngā kete kōrero, mātauranga āku ake a ngāi-Māori, kei hea mai tō mana.
