Wombs, worms and wolves: constructing cancer in Early Modern England
This essay examines medical and popular attitudes to cancer in the early modern period, c.1580â1720. Cancer, it is argued, was understood as a cruel and usually incurable disease, diagnosable by a well-defined set of symptoms understood to correspond to its etymological root, karkinos (the crab). It was primarily understood as produced by an imbalance of the humours, with women being particularly vulnerable. However, such explanations proved inadequate to make sense of the condition's malignancy, and medical writers frequently constructed cancer as quasi-sentient, zoomorphising the disease as an eating worm or wolf. In turn, these constructions materially influenced medical practice, in which practitioners swung between anxiety over âaggravatingâ the disease and an adversarial approach which fostered the use of radical and dangerous âcuresâ including caustics and surgery
Remediating modernity: youth, role models and behaviour change in 'new Nepal'
Communication for development (C4D) theorising, program design and practice, to a significant extent, remain driven by notions that communication inspires liberal-minded role models or âchange agentsâ operating at the local level. These individuals are typically described in terms of their willingness to pursue social change. In looking at the links between national pro-social change broadcasting and local practices of remediation and interpretation, this paper assesses the work of a large international NGO working to promote life skills, health awareness and civic responsibility amongst young people in Nepal. Such work charges young people to be agents of their own social change through the development of localised C4D initiatives that link with national media outputs and agendas. Inevitably, there is a degree of slippage in both meaning and message as local remediation of broader development issues occurs. Analysis reveals remediation of such issues to be a tangled practice in which key messages are reworked, made more conservative, and localised or mis-communicated.Natalie Greenland, Andrew Skus

New approaches to social skills training: Blended group interventions for girls with social communication difficulties
Social skills group interventions are increasing popular for children with social communication disorders but there is little evidence of their acceptability or effectiveness when delivered online. We report a feasibility study that adapted the Program for Education and Enrichment of Relational Skills (PEERS) to provide an intensive 8 week online delivery to female adolescents, blended with some faceâtoâface group meetings. A systematic multipleâcase series design with case tracking was developed, comprising a 3âmonth baseline, a 2âmonth intervention and a 3âmonth followâup period. Seven adolescents with Turner Syndrome and social communication difficulties (17â20âyears) took part, together with their parents. Acceptability and feasibility were assessed by means of qualitative feedback and attendance rates. Changes in social adaptation were tracked using measures of social knowledge, social behaviour and autistic symptoms, plus anxiety and selfâesteem. Attendance rates were consistently high and there were no dropouts. Qualitative feedback indicated the online format was acceptable to both the participants and their families. Objective outcome measures showed significant gains in social knowledge and improved social initiations from measures made during the preâintervention baseline. This proofâofâprinciple pilot study demonstrated blended social skills interventions are both feasible and acceptable to adolescent females with social communication difficulties
The Health-e Babies App for antenatal education: Feasibility for socially disadvantaged women
Background
The use of mobile technology such as phone applications (apps) has been proposed as an efficient means of providing health and clinical information in a variety of healthcare settings. We developed the Health-e Babies app as an Android smart phone application for pregnant women attending a tertiary hospital in a low socio-economic community, with the objective of providing health information about early pregnancy that would increase maternal confidence and reduce anxiety. Based on our earlier research, this form of health communication was viewed as a preferred source of information for women of reproductive age. However, the pilot study had a poor participation rate with 76% (n = 94) not completing the study requirements. These initial findings raised some very important issues in relation to the difficulties of engaging women with a pregnancy app. This paper analyses the characteristics of the participants who did not complete the study requirements in an attempt to identify potential barriers associated with the implementation of a pregnancy app.
Methods
This retrospective review of quantitative and qualitative data collected at the commencement of the Health-e Babies App trial, related to the participantâs communication technology use, confidence in knowing where to seek help and mental health status, maternal-fetal attachment and parenting confidence. Engagement and use of the Health-e Babies App was measured by the completion of a questionnaire about the app and downloaded data from participantâs phones. Mental health status, confidence and self-efficacy were measured by questionnaires.
Results
All women were similar in terms of age, race, marital status and level of education. Of the 94 women (76%) who did not complete the trial, they were significantly more anxious as indicated by State Trait Anxiety Inventory (p = 0.001 Student T-test) and more likely to be unemployed (50% vs 31%, p = 0.012 Student T-Test).
Conclusion
This study provides important information about the challenges associated with the implementation of a pregnancy app in a socially disadvantaged community. The data suggests that factors including social and mental health issues, financial constraints and technological ability can affect womenâs engagement with a mobile phone app

Discrete Wavelet Transform Analysis of the Electroretinogram in Autism Spectrum Disorder and Attention Deficit Hyperactivity Disorder
Background: To evaluate the electroretinogram waveform in autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) using a discrete wavelet transform (DWT) approach. Methods: A total of 55 ASD, 15 ADHD and 156 control individuals took part in this study. Full field light-adapted electroretinograms (ERGs) were recorded using a Troland protocol, accounting for pupil size, with five flash strengths ranging from -0.12 to 1.20 log photopic cd.s.m-2. A DWT analysis was performed using the Haar wavelet on the waveforms to examine the energy within the time windows of the a- and b-waves and the oscillatory potentials (OPs) which yielded six DWT coefficients related to these parameters. The central frequency bands were from 20-160 Hz relating to the a-wave, b-wave and OPs represented by the coefficients: a20, a40, b20, b40, op80, and op160, respectively. In addition, the b-wave amplitude and percentage energy contribution of the OPs (%OPs) in the total ERG broadband energy was evaluated. Results: There were significant group differences (p < 0.001) in the coefficients corresponding to energies in the b-wave (b20, b40) and OPs (op80 and op160) as well as the b-wave amplitude. Notable differences between the ADHD and control groups were found in the b20 and b40 coefficients. In contrast, the greatest differences between the ASD and control group were found in the op80 and op160 coefficients. The b-wave amplitude showed both ASD and ADHD significant group differences from the control participants, for flash strengths greater than 0.4 log photopic cd.s.m-2 (p < 0.001). Conclusion: This methodological approach may provide insights about neuronal activity in studies investigating group differences where retinal signaling may be altered through neurodevelopment or neurodegenerative conditions. However, further work will be required to determine if retinal signal analysis can offer a classification model for neurodevelopmental conditions in which there is a co-occurrence such as ASD and ADHD
The political economy of social capital: chronic poverty, remoteness and gender in rural Eastern Cape
Western Cape Social Capital Network (Department of Social Development, Western Cape Government) - Reports & ResearchThis paper uses two case studies drawn from in-depth ethnographic research in South Africa's Eastern Cape to interrogate and problematise the often simplistic or reductive ways in which the concept of social capital is used in debates about development and poverty alleviation. It argues that if the concept is to be useful at all, it needs to be used in ways that are sensitive to the fact that social capital inheres in social relations; that these social relations cannot be understood separately from the meaning-giving practices and discourses with which they are entangled; that the analysis of social capital requires an agent-centred approach that is alive to the way in which it is used, transformed, created, made and remade; and that such an analysis further more needs to be alive to the nature of power relations both on the micro-level and the macro-level of political economy. The analysis of social capital therefore should be linked to a careful account of the practices, networks, systems and processes that empower some and enable them to climb out of poverty, but which also marginalise and trap others in poverty that is deep-seated and chronic.Andries du Toit, Andrew Skuse, Thomas Cousin
The electroretinogram b-wave amplitude: a differential physiological measure for Attention Deficit Hyperactivity Disorder and Autism Spectrum Disorder
Background: Attention Deficit Hyperactivity Disorder (ADHD) is the most prevalent childhood neurodevelopmental disorder. It shares some genetic risk with Autism Spectrum Disorder (ASD), and the conditions often occur together. Both are potentially associated with abnormal glutamate and GABA neurotransmission, which can be modelled by measuring the synaptic activity in the retina with an electroretinogram (ERG). Reduction of retinal responses in ASD has been reported, but little is known about retinal activity in ADHD. In this study, we compared the light-adapted ERGs of individuals with ADHD, ASD and controls to investigate whether retinal responses differ between these neurodevelopmental conditions. / Methods: Full field light-adapted ERGs were recorded from 15 ADHD, 57 ASD (without ADHD) and 59 control participants, aged from 5.4 to 27.3 years old. A Troland protocol was used with a random series of nine flash strengths from â0.367 to 1.204 log photopic cd.s.mâ2. The time-to-peak and amplitude of the a- and b-waves and the parameters of the Photopic Negative Response (PhNR) were compared amongst the three groups of participants, using generalised estimating equations. / Results: Statistically significant elevations of the ERG b-wave amplitudes, PhNR responses and faster timings of the b-wave time-to-peak were found in those with ADHD compared with both the control and ASD groups. The greatest elevation in the b-wave amplitudes associated with ADHD were observed at 1.204 log phot cd.s.mâ2 flash strength (p <.0001), at which the b-wave amplitude in ASD was significantly lower than that in the controls. Using this measure, ADHD could be distinguished from ASD with an area under the curve of 0.88. / Conclusions: The ERG b-wave amplitude appears to be a distinctive differential feature for both ADHD and ASD, which produced a reversed pattern of b-wave responses. These findings imply imbalances between glutamate and GABA neurotransmission which primarily regulate the b-wave formation. Abnormalities in the b-wave amplitude could provisionally serve as a biomarker for both neurodevelopmental conditions
White matter microstructure correlates with autism trait severity in a combined clinicalâcontrol sample of high-functioning adults
AbstractDiffusion tensor imaging (DTI) studies have demonstrated white matter (WM) abnormalities in tracts involved in emotion processing in autism spectrum disorder (ASD), but little is known regarding the nature and distribution of WM anomalies in relation to ASD trait severity in adults. Increasing evidence suggests that ASD occurs at the extreme of a distribution of social abilities. We aimed to examine WM microstructure as a potential marker for ASD symptom severity in a combined clinicalâneurotypical population. SIENAX was used to estimate whole brain volume. Tract-based spatial statistics (TBSS) was used to provide a voxel-wise comparison of WM microstructure in 50 high-functioning young adults: 25 ASD and 25 neurotypical. The severity of ASD traits was measured by autism quotient (AQ); we examined regressions between DTI markers of WM microstructure and ASD trait severity. Cognitive abilities, measured by intelligence quotient, were well-matched between the groups and were controlled in all analyses. There were no significant group differences in whole brain volume. TBSS showed widespread regions of significantly reduced fractional anisotropy (FA) and increased mean diffusivity (MD) and radial diffusivity (RD) in ASD compared with controls. Linear regression analyses in the combined sample showed that average whole WM skeleton FA was negatively influenced by AQ (p=0.004), whilst MD and RD were positively related to AQ (p=0.002; p=0.001). Regression slopes were similar within both groups and strongest for AQ social, communication and attention switching scores. In conclusion, similar regression characteristics were found between WM microstructure and ASD trait severity in a combined sample of ASD and neurotypical adults. WM anomalies were relatively more severe in the clinically diagnosed sample. Both findings suggest that there is a dimensional relationship between WM microstructure and severity of ASD traits from neurotypical subjects through to clinical ASD, with reduced coherence of WM associated with greater ASD symptoms. General cognitive abilities were independent of the relationship between WM indices and ASD traits
