title: The Influence of Contextual Aspects on New Zealand Muslim Males' Environmentally Ethical Behaviour

authors: Yaacob, Mashitoh

subjects: environmentally ethical behaviour (EEB)

abstract: This study's aim was to investigate the strength of contextual aspects' influences on environmentally ethical behaviour (EEB). A survey method with a selfadministered questionnaire was used and a cross-section of the Muslim male population of New Zealand was taken. The qualitative interviews and email questionnaires were also utilised to further explain the survey results. The linear regression analyses show correlations between contextual aspects (i.e., social, religious, economic, political, and demographic) and EEB (pre-cycling, re-use and recycling). Results indicate that the contextual aspects are influential on EEB in many ways and degrees. A model describing the relationship was developed. The economic aspect statistically significantly related to EEB the strongest. The qualitative interview and email questionnaire data support the findings of the survey. The relationship was positive, meaning that the more the consumers were influenced by the economic aspect to behave in an environmentally ethical way, the more they were likely to perform EEB. Compared to the economic aspect, white collar workers, number of household occupant, work involvement with the environment, type of house, and age had a weaker statistically significant relationship with EEB. The relationships were positive, meaning that the better the consumers' occupation (i.e., white collar workers), the more household member they had (i.e., 4 and above), the higher their level of work involvement with the environment, and the better their dwelling (i.e., bungalow or semi-detached houses), the more they were likely to perform EEB. However, the relationship between age and EEB was negative, meaning that the younger the consumers the more they were likely to perform EEB. However, the results of this study, from both the survey and the interview methods, indicate that demographic characteristics were not as important as the contextual aspects, particularly the economic aspect, in understanding consumers' EEB. This study shows that the economic aspect was very important in understanding consumers' EEB compared to the other contextual aspects even the political aspect was statistically significantly related to EEB via the economic aspect. Thus, the economic aspect should be used optimally by public and private sector managers to promote EEB.

title: Development and Characterisation of Plasmonic Devices for Sensing Applications

authors: Sedoglavich, Nemanya

subjects: Plasmonic

abstract: In recent years, discoveries and advances that utilise nano-scale (10^-9m) structures and associated phenomena have led to a number of entirely new areas of research in the fields of physics, chemistry, biology, and materials science. The photonic field of plasmonics is the study of light interaction with nanometer-scaled metal-dielectric features, which gives rise to a variety of phenomena, including surface plasmon resonance, localised surface plasmon resonance, and metal enhanced fluorescence. The focus of this thesis is on the development and characterisation of nanophotonic devices, which utilise plasmonic phenomena and have potential for sensor applications.
During the course of this research a surface plasmon resonance analysis platform was devised, which utilises the gold grating of commercially available compact disks as the sensing substrate. This measurement method offers a high resolution refractive index analysis of gases and surface chemistry and is capable of analysing a large number of samples by scanning over the entire disk surface. The system implements a method of phase-polarisation contrast to improve the sensing performance. It enhances signal detection through redistributing the residual p-polarised waves, which have been strongly absorbed by the surface plasmon resonance substrate/sensor. This effectively lowers the reflected light intensity at the surface plasmon resonance minimum. The scheme results in the deepening of the intensity minimum to below 3.5% reflection and the enhancement of resonance to non-resonance contrast by up to 14 times, and thereby increasing sensitivity.
A range of new nanophotonic structures have been modelled, developed, fabricated, and characterised, which we call wavelength and polarisation selective polariton generators (SPGs). These polarisation-sensitive structures combine a tuneable plasmon resonator and a subwavelength aperture to selectively generate and transmit polaritons of a desired wavelength through a central nanohole. Individual SPGs permit modulation of transmission intensity, with calculated enhanced optical transmission (ratio of output to input flux) of up to 10 and up to 4-fold measured amplitude modulation. The paired SPGs gave rise to multiple spectrally discrete transmission peaks which, when modulated, provide a multi-state operation in a single device. The measured amplitude modulation was up to 10-fold. For the linearly continuous SPG, by controlling the polarisation as a tuning variable, it selectively generated and transported polaritons of a desired wavelength. It exhibited a spectral shift of 40 nm over the full range of polarisation angles. The modelled enhanced optical transmission was calculated to be up to 17.2. An instrument was developed for measuring and characterising light transmission through single nanoholes, nanohole arrays, and other complex structures. The operational characteristics of these elements show close agreement between model predictions and experimental data. It also demonstrates new designs of plasmonic structures which utilise selective behaviour based on the polarisation of incident light.

title: “Papatuanuku/papa:” Some thoughts on the oppositional grounds of the doctoral experience

authors: Mika, Carl Te Hira

subjects: Kaupapa

abstract: There are significant challenges that face Māori students and supervisors as a “doctoral team.” Perhaps the most fundamental of these is that there is a metaphysics at work in writing and talking that Māori are encouraged to speculate on and reclaim. One term for this metaphysics, “Papatūānuku” (often abbreviated to “Papa”), signifies an active entity that rejects strict definition but influences both doctoral text and team. This article proposes that student and supervisor must simultaneously glance towards the conventions of academic writing and recollect Papatūānuku as potential being in the doctoral process.
