Visual Evidence From Above: Assessing The Value Of Earth Observation Satellites For Supporting Human Rights, Tanya Notley, Camellia B. Webb-Gannon

Faculty of Social Sciences - Papers (Archive)

Public access to data collected by remote sensing Earth Observation Satellites has, until recently, been very limited. Now, citizens and rights advocacy groups are increasingly utilising satellite-collected images to interrogate justice issues; to document, prevent and verify rights abuses; and to imagine and propose social change. Yet while other communication technologies have received substantial critical analysis regarding their value as tools of social justice, activism and resistance, satellites have received comparatively scant attention. This article examines the uses of satellite-collected images in human rights contexts including the opportunities, challenges and risks they pose. We conclude this examination by arguing that …

Using Questionnaires In Qualitative Human Geography, Pauline M. Mcguirk, Phillip O'Neill

Faculty of Social Sciences - Papers (Archive)

This chapter deals with questionnaires, an information-gathering technique used frequently in mixed-method research that draws on quantitative and qualitative data sources and analysis. We begin with a discussion of key issues in the design and conduct of questionnaires. We then explore the strengths and weaknesses for qualitative research of various question formats and questionnaire distribution and collection techniques, including online techniques. Finally, we consider some of the challenges of analyzing qualitative responses in questionnaires, and we close with a discussion of the limitations of using questionnaires in qualitative research.

Broaden Research On The Human Dimensions Of Climate Change, Noel Castree

Faculty of Social Sciences - Papers (Archive)

Human actions are causing global environmental changes that, in turn, have significant human impacts and demand human responses. The magnitude of change, impact and response will only increase in the decades to come. For too long science, technology, engineering and mathematics (STEM) subjects have dominated research into how people are altering the atmosphere, biosphere, cryosphere, hydrosphere and lithosphere. We now urgently need to understand, and seek to alter, human behaviour so that our planet remains a liveable one for all people.

Acute And Chronic Effects Of Cannabinoids On Human Cognition-A Systematic Review, Samantha J. Broyd, Hendrika H. Van Hell, Camilla Beale, Murat Yucel, Nadia Solowij

Faculty of Social Sciences - Papers (Archive)

Cannabis use has been associated with impaired cognition during acute intoxication as well as in the unintoxicated state in long-term users. However, the evidence has been mixed and contested, and no systematic reviews of the literature on neuropsychological task-based measures of cognition have been conducted in an attempt to synthesize the findings. We systematically review the empirical research published in the past decade (from January 2004 to February 2015) on acute and chronic effects of cannabis and cannabinoids and on persistence or recovery after abstinence. We summarize the findings into the major categories of the cognitive domains investigated, considering sample …

The Spatiotemporal Hemodynamic Response Function For Depth-Dependent Functional Imaging Of Human Cortex, Alexander M. Puckett, K M. Aquino, Peter Robinson, Michael Breakspear, Mark M. Schira

Faculty of Social Sciences - Papers (Archive)

The gray matter of human cortex is characterized by depth-dependent differences in neuronal activity and connections (Shipp, 2007) as well as in the associated vasculature (Duvernoy et al., 1981). The resolution limit of functional magnetic resonance imaging (fMRI) measurements is now below a millimeter, promising the non-invasive measurement of these properties in awake and behaving humans (Muckli et al., 2015; Olman et al., 2012; Ress et al., 2007). To advance this endeavor, we present a detailed spatiotemporal hemodynamic response function (HRF) reconstructed through the use of high-resolution, submillimeter fMRI. We decomposed the HRF into directions tangential and perpendicular to the …

Path Integration Deficits During Linear Locomotion After Human Medial Temporal Lobectomy, John W. Philbeck, Marlene Behrmann, Lucien Levy, Samuel J. Potolicchio, Anthony J. Caputy

Marlene Behrmann

Animal navigation studies have implicated structures in and around the hippocampal formation as crucial in performing path integration (a method of determining one's position by monitoring internally generated self-motion signals). Less is known about the role of these structures for human path integration. We tested path integration in patients who had undergone left or right medial temporal lobectomy as therapy for epilepsy. This procedure removed approximately 50% of the anterior portion of the hippocampus, as well as the amygdala and lateral temporal lobe. Participants attempted to walk without vision to a previously viewed target 2-6 m distant. Patients with right, …

Background

The National Human Papillomavirus (HPV) Vaccination Program in Australia commenced in 2007 for females and in 2013 for males, using the quadrivalent HPV vaccine (HPV 6,11,16,18). Thus far, we have demonstrated very substantial reductions in genital warts and in the prevalence of HPV among young Australian women, providing early evidence for the success of this public health initiative. Australia has a long history of school-based vaccination programs for adolescents, with comparatively high coverage. However, it is not clear what factors promote success in a school vaccination program. The HPV.edu study aims to examine: 1) student knowledge about HPV vaccination; …

High-Resolution In Vivo Manual Segmentation Protocol For Human Hippocampal Subfields Using 3t Magnetic Resonance Imaging, Julie Winterburn, Jens C. Pruessner, Chavez Sofia, Mark M. Schira, Nancy J. Lobaugh, Aristotle N. Voineskos, M Mallar Chakravarty

Faculty of Social Sciences - Papers (Archive)

The human hippocampus has been broadly studied in the context of memory and normal brain function and its role in different neuropsychiatric disorders has been heavily studied. While many imaging studies treat the hippocampus as a single unitary neuroanatomical structure, it is, in fact, composed of several subfields that have a complex three-dimensional geometry. As such, it is known that these subfields perform specialized functions and are differentially affected through the course of different disease states. Magnetic resonance (MR) imaging can be used as a powerful tool to interrogate the morphology of the hippocampus and its subfields. Many groups use …

Medial Temporal Lobe Roles In Human Path Integration, Naohide Yamamoto, John W. Philbeck, Adam J. Woods, Daniel A. Gajewski, Joeanna C. Arthur, Samuel J. Potolicchio, Lucien Levy, Anthony J. Caputy

Faculty of Social Sciences - Papers (Archive)

Path integration is a process in which observers derive their location by integrating self-motion signals along their locomotion trajectory. Although the medial temporal lobe (MTL) is thought to take part in path integration, the scope of its role for path integration remains unclear. To address this issue, we administered a variety of tasks involving path integration and other related processes to a group of neurosurgical patients whose MTL was unilaterally resected as therapy for epilepsy. These patients were unimpaired relative to neurologically intact controls in many tasks that required integration of various kinds of sensory self-motion information. However, the same …

The cerebellum has classically been linked to motor learning and coordination. However, there is renewed interest in the role of the cerebellum in non-motor functions such as cognition and in the context of different neuropsychiatric disorders. The contribution of neuroimaging studies to advancing understanding of cerebellar structure and function has been limited, partly due to the cerebellum being understudied as a result of contrast and resolution limitations of standard structural magnetic resonance images (MRI). These limitations inhibit proper visualization of the highly compact and detailed cerebellar foliations. In addition, there is a lack of robust algorithms that automatically and reliably …

Hyper-Arousal Decreases Human Visual Thresholds, Adam J. Woods, John W. Philbeck, Philip W. Wirtz

Faculty of Social Sciences - Papers (Archive)

Arousal has long been known to influence behavior and serves as an underlying component of cognition and consciousness. However, the consequences of hyper-arousal for visual perception remain unclear. The present study evaluates the impact of hyper-arousal on two aspects of visual sensitivity: visual stereoacuity and contrast thresholds. Sixty-eight participants participated in two experiments. Thirty-four participants were randomly divided into two groups in each experiment: Arousal Stimulation or Sham Control. The Arousal Stimulation group underwent a 50-second cold pressor stimulation (immersing the foot in 0–2° C water), a technique known to increase arousal. In contrast, the Sham Control group immersed their …

The Forms Of Bullying Scale (Fbs): Validity And Reliability Estimates For A Measure Of Bullying Victimization And Perpetration In Adolescence, Therese M. Shaw, Julian J. Dooley, Donna S. Cross, Stephen R Zubrick, Stacey K. Waters

Research outputs 2013

The study of bullying behavior and its consequences for young people depends on valid and reliable measurement of bullying victimization and perpetration. Although numerous self-report bullying-related measures have been developed, robust evidence of their psychometric properties is scant, and several limitations inhibit their applicability. The Forms of Bullying Scale (FBS), with versions to measure bullying victimization (FBS-V) and perpetration (FBS-P), was developed on the basis of existing instruments, for use with 12-to 15-year-old adolescents to economically, yet comprehensively measure both bullying perpetration and victimization. Measurement properties were estimated. Scale validity was tested using data from 2 independent studies of 3,496 …

Editors' Introduction: Human Geography, Derek Gregory, Noel Castree

Faculty of Social Sciences - Papers (Archive)

When we were invited by Sage to identify published work in human geography that represents what is best and most distinctive about the field it seemed an impossible task (it still does) because there is such a rich volume of material to draw from. We decided to focus on Englishlanguage and to a lesser extent other European contributions, although we are acutely aware of the irony, even the imperialism, of limiting a field like human geography to knowledges rooted in only a fraction of the world. We discuss below the dangers of delimiting Geography as a European or Euro-American science, …

Deficits in memory function are an incapacitating aspect of various psychiatric and neurological disorders. Animal studies have recently provided strong evidence for involvement of the endocannabinoid (eCB) system in memory function. Neuropsychological studies in humans have shown less convincing evidence but suggest that administration of cannabinoid substances affects encoding rather than recall of information. In this study, we examined the effects of perturbation of the eCB system on memory function during both encoding and recall. We performed a pharmacological MRI study with a placebo-controlled, crossover design, investigating the effects of Δ9-tetrahydrocannabinol (THC) inhalation on associative memory-related brain function in 13 …

Cell Viability And Cytokine Production Of Human Alveolar Epithelial Cells Following Exposure To Sulphur Dioxide, Shahnaz Bakand, Chris Winder, Amanda Hayes

Faculty of Social Sciences - Papers (Archive)

Exposure to air pollutants is significantly associated with health risks ranging from bronchial reactivity to morbidity and mortality. However, the precise mechanisms are not always fully understood. The aim of this study was to investigate the effects of sulphur dioxide (SO₂) on cell viability and cytokine production of A549-human pulmonary epithelial cells. Test atmospheres of SO₂ were generated using a direct dilution method and calibrated by ion-chromatography. Test atmospheres were delivered to lung cells cultured on porous membranes (0.4 μm) using Harvard Navicyte horizontal diffusion chamber systems. The cytotoxic endpoints were investigated using the MTS (tetrazolium salt; …

The Foveal Confluence In Human Visual Cortex, Mark M. Schira, C W. Tyler, Michael Breakspear, Branka Spehar

Faculty of Social Sciences - Papers (Archive)

The human visual system devotes a significant proportion of its resources to a very small part of the visual field, the fovea. Foveal vision is crucial for natural behavior and many tasks in daily life such as reading or fine motor control. Despite its significant size, this part of cortex is rarely investigated and the limited data have resulted in competing models of the layout of the foveal confluence in primate species. Specifically, how V2 and V3 converge at the central fovea is the subject of debate in primates and has remained “terra incognita” in humans. Using high-resolution fMRI (1.2 …

Negotiating Value: Comparing Human And Animal Fracture Care In Industrial Societies, Christopher J. Degeling

Faculty of Social Sciences - Papers (Archive)

At the beginning of the twentieth century, human and veterinary surgeons faced the challenge of a medical marketplace transformed by technology. The socioeconomic value ascribed to their patients was changing, reflecting the increasing mechanization of industry and the decreasing dependence of society on nonhuman animals for labor. In human medicine, concern for the economic consequences of fractures "pathologized" any significant level of posttherapeutic disability, a productivist perspective contrary to the traditional corpus of medical values. In contrast, veterinarians adapted to the mechanization of horsepower by shifting their primary professional interest to companion animals; a type of patient generally valued for …

Development And Validation Of The Counterfactual Thinking For Negative Events Scale, Tarika Daftary Kapur, Mark S. Rye, Melissa B. Cahoon, Rahan S. Ali

Department of Justice Studies Faculty Scholarship and Creative Works

We examined the psychometric properties of the newly created Counterfactual Thinking for Negative Events Scale (CTNES) in two studies involving university undergraduates. In Study 1 (N = 634), factor analysis revealed four subscales that correspond with various types of counterfactual thinking: Nonreferent Downward, Other-Referent Upward, Self-Referent Upward, and Nonreferent Upward. The subscales were largely orthogonal and had adequate internal consistency and test–retest reliability. The CTNES subscales were positively correlated with a traditional method of assessing counterfactual thinking and were related as expected to contextual aspects of the negative event, negative affect, and cognitive style. In Study 2 (N …

In Vitro Cytotoxicity Assessment Of Selected Nanoparticles Using Human Skin Fibroblasts, Finance Dechsakulthorn, Amanda Hayes, Shahnaz Bakand, Lucky Joeng, Chris Winder

Faculty of Social Sciences - Papers (Archive)

Zinc oxide (ZnO) and Titanium oxide (TiO₂) are two chemical compound with very wide industrial and commercial applications, particularly as pigments. Due to their physical properties, both compounds are also used as sunscreen ingredients for protect from UV radiation. At the nano-scale, ZnO and TiO₂ have proven to have a similar level of protection compared to normal-scale sunscreen particles. An advantage of the topical use of nano-scale ingredients in sunscreens is their transparency compared to the white residue left on skin with normal scale particles. However, the potential toxicity of these nanoparticles is not well understood. The aim of this …

In Vitro Cytotoxicity Of Formaldehyde And Glutaraldehyde Mixtures In Human Cells, Shahnaz Bakand, Chris Winder, Christian Khalil, Amanda Hayes

Faculty of Social Sciences - Papers (Archive)

The cytotoxicity of formaldehyde, glutaraldehyde and their binary mixtures was determined using the MTS (tetrazolium salt; Promega) in vitro assay. Cytotoxicity endpoints were investigated in human cells including; pulmonary type II-like epithelial cell lines (A549), hepatoma cell lines (HepG2) and skin fibroblasts. In order to study the cytotoxic effects of airborne formaldehyde, standard atmospheres at concentrations below 10 ppm (12.3 mg/m³) were generated using a dynamic diffusion method. Formaldehyde was bubbled through serum free culture media and cell viability was investigated after treating cells with formaldehyde air samples. HepG2 cells were found to be more sensitive (IC_{50 …}

Keeping The Faith: The Impact Of Human Services Restructuring On Catholic Social Welfare Services, Gail Winkworth, Peter J. Camilleri

Faculty of Social Sciences - Papers (Archive)

Church related agencies are major providers of community services in Australia (Lyons, 2001:34-35). While the history of church related welfare service provision is not well known in Australia it is asserted that many have a long tradition of outreach and service provision to marginalised groups regardless of the government social policy of the day (ACSWC, 2000; Mendes, 2003). This paper examines the current environment of human services restructuring and the impact of the shift to contractualism on one church related provider: Catholic social welfare provision in Australia. It explores the significance of the church's social teachings and history on concerns …
