title: Use of high-intensity data to define large river management units: A case study on the lower Waikato River, New Zealand

authors: Pingram, Michael Alister

subjects: biofish

abstract: The importance of environmental heterogeneity in lotic ecosystems is well recognised in river management, and continues to underpin studies of hierarchical patch dynamics, geomorphology and landscape ecology. We evaluated how physical characteristics and water chemistry measurements at high spatiotemporal resolution define channel units of potential ecological importance along 134 km of the lower Waikato River in North Island, New Zealand. We used multivariate hierarchical clustering to classify river reaches in an a priori unstructured manner based on (i) high-frequency, along-river water quality measurements collected in four seasons and (ii) river channel morphology data resolved from aerial photos for 1-km long reaches. Patterns of channel character were shaped by the depth and lateral complexity of constituent river reaches, while water quality patterns were represented by differences in clarity, chlorophyll fluorescence and specific conductance driven by tributary inflows in the mid-section of the river and tidal cycles in the lower section. Management units defined by physical characteristics or water quality did not necessarily align with boundaries typically reflecting clinal processes (e.g. tidal influence) or geomorphic, network or anthropogenic discontinuities. The results highlight the dynamic spatial and temporal properties of large rivers and the need to define clear objectives when deriving spatial units for management and research. Given that actions and targets for physical channel and water quality management may differ, the spatial extent identified for each of these does not necessarily need to directly coincide, although both should be considered in decision making and experimental design.

title: The Representation of Gender in Contemporary Chinese Television Advertising: An Analysis of Content, Meaning, and Production

authors: Shao, Yun

subjects: advertising

abstract: This thesis examines how gender is portrayed in Chinese television commercials and how these representations reflect the social and cultural contexts of their production and the institutional practices of advertising production personnel. To date, while there have been a plethora of studies on gender representation in advertising in western contexts only limited attention has been given to Chinese advertising portrayals of gender. This study, therefore, explores particular ways in which femininity and masculinity are discursively constructed, and how this process, in turn, contributes to reinforcing and/or challenging certain gender ideologies, in particular those found in Chinese Confucian culture. The study is unique in its approach to Chinese television advertising in that it combines methods from textual analysis (quantitative content analysis, semiotic analysis and critical discourse analysis) and empirical research (interview). A sample of 679 television commercials was collected and analysed in this investigation. Content analysis was initially applied to identify recurrent patterns and characteristics of gender representation which, in turn, formed the basis for in-depth semiotic and discourse analysis. Specific signs, images, codes, discourses and myths were subsequently discussed. The study also included semi-structured interviews with 26 Chinese advertising personnel in order to understand their multiple dispositions toward gender and their actual experiences of depicting female and male characters in the creative process. Several main findings emerged from this study. The portrayal of gender in Chinese television commercials is complex because it embodies a series of simultaneously conflicting and complementary discourses on what constitute femininity and masculinity. The results of the content analysis revealed that the representation of gender in this study’s sample still remains stereotypical in terms of the different distribution of the sexes across product category, role, dress, age, credibility and voice-over. By focusing on the constructs of gender in domestic, occupational and recreational contexts, the use of semiotic and discourse analysis revealed that Chinese television advertising not only portrays women and men in line with the significant aspects embedded in both Chinese and western patriarchal traditions, but is also constitutive of cultural shifts in gender ideologies through highlighting modern (western) values. In addition, the interview findings yielded support for the conclusions of textual analysis, demonstrating that the process of advertising production is significantly influenced by traditional and modern gender values, the restriction of advertising regulations, client expectations, and the professionals’ divergent perceptions of gender and their assumptions about the audience.

title: Self-decolonisation in Aotearoa: Pushing through programmatic Pākehā paralysis

authors: Weijers, Dan M.

abstract: Te reo, tīkanga, mātauranga, te Ao, and kaupapa Māori are finally seeing a resurgence in Aotearoa. This revitalisation is occurring in the tertiary education sector, but staff and skill deficits are holding back many academic disciplines. This chapter documents the challenges facing a traditionally colonial tertiary programme—philosophy— attempting to de-colonise itself. The overlapping nature of the challenges can make decolonising appear to be so difficult that some programmes may feel paralysed. This chapter argues that the importance of decolonisation requires that programmes push through any paralysis they may be experiencing by prioritising decolonisation above other goals.
