    Exploring Process Dissociation as a Tool for Investigating Discrimination in Hiring Situations

    Process dissociation is introduced as a way to overcome methodological limitations currently hindering sexism research. Researchers have identified two main types of sexism in hiring contexts. Meta-analyses confirm that men are traditionally advantaged over women (Tosi & Einbender, 1985), and that both genders encounter discrimination when applying to a job typically associated with the other gender (Davison & Burke, 2000). One problem is that these two biases are often confounded. As a result, researchers have hitherto been limited to showing that the two biases exist, but are largely unable to quantify them. A possible solution might be process dissociation. It provides a way of measuring processes without the need to isolate them (Jacoby, 1991). The purpose of the dissertation was to explore process dissociation within the context of hiring decisions. The current dissertation consisted of three parts. A pretest developed materials for use in the main studies. Study 1 then explored how process dissociation estimates compare to existing tools commonly used to study sexism. The pro-male bias was found to relate to old-fashioned sexism. The gender-job fit bias related to benevolent sexism. Measures of bias appeared uncontaminated by internal and external motivation to respond without sexism. Biases did not relate as expected to other measures of sexism, including hostile, modern, and neo-sexism, and two Implicit Association Tests. Finding differential relationships with some expected correlates supports the validity of process dissociation parameters and helps elucidate how the parameters fit within existing sexism constructs. Study 2 further investigated validity through independent manipulation. Participants were randomly assigned to receive one of four word-sorting tasks containing primes intended to selectively influence one of the two types of bias. These manipulations had the desired effect for only some participants. Though both biases were selectively affected, a full double dissociation was not achieved. Consequently, Study 2 results provide only partial support for the proposed causal mechanisms and independence of process dissociation parameters. Overall, results illustrate that process dissociation may be a helpful tool for use in research on sexism in hiring decisions. Limitations of process dissociation and potential next steps are discussed

    Tuateawa

    The Tuateawa project seeks to inform ecological understanding using analyses of soundscapes. Sound recordings are made in specific locations near Tuateawa in the Coromandel peninsula. This area is being monitored for the eradication of pests such as possums, stoats and rats. The research looks at how the soundscapes change over time, in particular: how is bird life affected by the presence of introduced noxious pests? And, how does human activity influence natural behaviours? The project is a form of documentary capturing detailed sound recordings every season for three or more years. The sound data is analysed for noticeable shifts in frequency and loudness, and output as various visual abstractions, the first of which is an audio visual work for LCD screens and speakers at Ramp Gallery 7-11 December 2020. The intended audience is intermediate age children to get them thinking about how these soundscapes might be understood and focused on through a less ‘scientific’ medium

    The impact of Chinese import penetration on the South African manufacturing sector

    Get PDF
    This article uses a Chenery-type decomposition and econometric estimation to evaluate the impact of Chinese trade on production and employment in South African manufacturing from 1992 to 2010. The results suggest that increased import penetration from China caused South African manufacturing output to be 5 per cent lower in 2010 than it otherwise would have been. The estimated reduction of total employment in manufacturing as a result of trade with China is larger – in 2010 about 8 per cent – because the declines in output were concentrated on labour-intensive industries and because the increase in imports raised labour productivity within industries

    Damage detection in a composite wind turbine blade using 3D scanning laser vibrometry

    As worldwide wind energy generation capacity grows, there is an increasing demand to ensure structural integrity of the turbine blades to maintain efficient and safe energy generation. Currently, traditional non-destructive testing methods and visual inspections are employed which require the turbine to be out-of-operation during the inspection periods, resulting in costly and lengthy downtime. This study experimentally investigates the potential for using Lamb waves to monitor the structural integrity of a composite wind turbine blade that has been subject to an impact representative of damage which occurs in service. 3D scanning laser vibrometry was used to measure Lamb waves excited at three different frequencies both prior to, and after, impact to identify settings for an optimal system. Signal processing techniques were applied to the datasets to successfully locate the damage and highlight regions on the structure where the Lamb wave was significantly influenced by the presence of the impact damage. Damage size resulting from the impact was found to correlate well with the laser vibrometry results. The study concluded that acousto-ultrasonic-based structural health monitoring systems have great potential for monitoring the structural integrity of wind turbine blades
