Portrait of Sixteenth-Century Disability? Quentin Matsys’s A Grotesque Old Woman

Scholars rarely examine art works from a disability studies perspective; their analyses often misinterpret those works, reinforcing contemporary assumptions about disability and its past representations. Accordingly, this paper examines a portrait by sixteenth-century Antwerp artist Quentin Matsys (1466-1529) from a historically situated disability studies perspective. A Grotesque Old Woman (c.1513) has been understood in terms of abnormality. Existing scholarship has suggested that she represents physical, gender, and sexual deviance in the spirit of Erasmian allegories, or an individual with Paget’s disease (http://en.wikipedia.org/wiki/Paget%27s_disease_of_bone). Although these interpretations may inform contemporary scholarship, they shed little light on sixteenth-century disability and its artistic representations. This paper demonstrates how the portrait reflects a cultural transition from an earlier collective, religious model of disability to a more “municipal” one which considers disability vis-à-vis individuals engaged in daily commercial or personal activities. This analysis provides insight into how disability was understood in Matsys’s time, contributes to our understanding of the Dutch allegorical and portraiture traditions, and demonstrates what a historically situated disability model offers future research on artistic representations of disability

Detecting targeted data poisoning attacks on deep neural networks

Deep neural networks (DNNs) are widely used for various facial image-recognition purposes, including facial recognition and subsequent authentication, and the detection of altered facial images. Unfortunately, due to their widespread use, there have been many works that focus on attacking such DNN-based systems for nefarious purposes. One type of attack on DNNs is called a "targeted data poisoning" attack, which has the goal of injecting photos into the DNNs training set in such a way as to cause the DNN to learn malicious behavior. In the context of facial authentication, this could correspond to unauthorized users gaining access to a target's account, whereas, in deepfake detection, this could translate to causing the DNN to fail to identify when a target's face is the subject of a deepfake image. This report describes targeted data poisoning attacks and proposed defenses on DNN-based systems for facial authentication and deepfake detection, each achieving high accuracy ([greater than] 95 percent) in most cases.Includes bibliographical references

Ethical perspectives on advances in biogerontology

Worldwide populations are aging with economic development as a result of public health initiatives and advances in therapeutic discoveries. Since 1850, life expectancy has advanced by 1 year for every four. Accompanying this change is the rapid development of anti‐aging science. There are three schools of thought in the field of aging science. One perspective is the life course approach, which considers that aging is a good and natural process to be embraced as a necessary and positive aspect of life, where the aim is to improve the quality of existing lifespan and “compress” morbidity. Another view is that aging is undesirable, and that rejuvenation and indeed immortality are possible since the biological basis of aging is understood, and therefore, strategies are possible for engineering negligible senescence. Finally, a hybrid approach is that life span can be extended by anti‐aging medicines but with uncertain effects on health. While these advances offer much promise, the ethical perspectives are seldom discussed in cross‐disciplinary settings. This article discusses some of the key ethical issues arising from recent advances in biogerontology

A survey of child care centers about breastfeeding support in Adelaide, South Australia.

Author's version made available in accordance with Publisher's copyright policy.Background: Australia has high rates of breastfeeding initiation, with a consistent decline over the first year. Furthermore, there is a growing trend of maternal employment and rising numbers of children enrolled in different types of child care services, both of which can have a negative impact on breastfeeding. Objectives: To provide evidence to better inform implementation of breastfeeding-friendly strategies in child care settings, this study examined breastfeeding policy and practice in child care centers in metropolitan Adelaide. Methods: The paper reports on a survey sent to 292 child care centers in metropolitan Adelaide in 2010. The survey collected information on center location and type, number of enrolled children under age 2, and number of breastfed babies. The survey also included questions about breastfeeding facilities and support, breastfeeding policies, staff training, and barriers to and recommendations to enhance breastfeeding support in child care centers. Results: Of the 62 completed returned surveys (21% response rate), 43 centers (69.4%) reported that they currently have children who receive breast milk at the center; however, in most centers, the total number of breastfed children was reported to be between 1 and 4; 76% reported that the center was supportive of exclusive breastfeeding for 6 months; and 80.6% had statements on breastfeeding as part of their food and nutrition policies or guidelines. Furthermore, 64.5% reported there was no formal or informal training for staff on breastfeeding support, but 50% reported that staff members do provide breastfeeding advice to mothers of children in their center. Conclusions: Despite some strategies in place to support breastfeeding, there are no standards on breastfeeding policies, practices, and training in child care settings.Therefore, the extent and scope of such support depend on parental request and the perceptions and attitudes of child care center staff toward breastfeeding

Prevalence and correlates of Trichomonas vaginalis infection among female US federal prison inmates

BACKGROUND: Previous studies have observed high prevalences of Trichomonas vaginalis infection among women entering US jails and state prisons (22%–47%). We sought to determine the prevalence among women incarcerated in 2 US female-only federal prisons. METHODS: Female inmates were recruited at 2 prisons (n = 624). Participants completed a self-administered questionnaire and provided self-collected first-catch urine and vaginal swab specimens. Specimens were tested for T. vaginalis DNA. RESULTS: Approximately 8.5% of participants at the first prison, and 8.3% at the second prison had a positive urine result, vaginal swab result or both, for a combined prevalence of 8.5%. Using positivity in either specimen as the reference standard, urine polymerase chain reaction had a sensitivity of 66.7% and vaginal swab polymerase chain reaction had a sensitivity of 84.4%. The only significant positive correlate of T. vaginalis infection was lower household income before arrest. Other variables nonsignificantly positively correlated with T. vaginalis were being employed at the time of arrest, having experienced sexual, physical, or emotional abuse by a family member, having a parent who had not had a drug or alcohol addiction, never exchanging sex for money or drugs, ever being pregnant, having abnormal vaginal bleeding/spotting, and having concurrent chlamydia or gonorrhea. CONCLUSIONS: Although not as high as in other studies of women entering US jails and state prisons, our observed T. vaginalis prevalence of 8.5% was much higher than in the general US population. Therefore, screening for T. vaginalis infection may be warranted at federal prison entry, as well as sexual health education during prison stay

Analysis of breastfeeding policies and practices in childcare centres in Adelaide, South Australia

Author version made available in accordance with publisher policy.Breastfeeding policies and practices were analysed in childcare settings in the metropolitan area of Adelaide, South Australia. Childcare centres were purposively selected based on their geographical location, type and socioeconomic score of the area. Qualitative inquiry approach was employed by undertaking interviews with childcare centres’ director or baby house coordinator to explore their perception towards breastfeeding practice and support within their centre. Breastfeeding related policy documents, where available, were also collected during the interviews to triangulate data. A total of 15 face-to-face interviews were conducted. Six childcare centres had a written policy specifically on breastfeeding support, although the technical issues of handling breastmilk were included in most centres’ food and nutrition guidelines. Most participants believed that decision to breastfeed is the personal choice of parents, and hence saw the childcare centre’s role as supporting parental choice whether it is breastfeeding or not. The provision of physical space to breastfeed and facilities to store the expressed breast milk were the most common practices in support of parents who had chosen to continue breastfeeding. Participants perceived mothers’ work-related issues such as distance from the centre, time, and unsupportive workplace the most important barriers that led to early introduction of bottle feeding or breastfeeding cessation. Most childcare centres support breastfeeding in a more passive than active way. Breastfeeding promotion needs to be an integral part of childcare centres training, policy and practice if an increased rate of breastfeeding is to be achieved particularly amongst working mothers.This work was made possible by a grant from the Faculty of Health Science, Flinders University

Contribution of Benthic Processes to the Growth of Ooids on a Low-Energy Shore in Cat Island, The Bahamas

Ooids are typically found in frequently reworked coastal sediments, and are thought to accrete by inorganic chemical precipitation around moving grains. The high organic content and the presence of biosignatures, however, suggest that ooids interact with benthic microbial communities. Here, we investigate the role of benthic processes on ooid growth on a leeward shore of Cat Island, The Bahamas. Polished ooids are present in the surf zone, whereas dull ooids and grapestones are present in microbially colonized sediments seaward of the surf zone. Wave hydrodynamics and sediment transport modeling suggest that microbially colonized sediments are mobilized at monthly time scales. We propose a new conceptual model for both ooids and grapestone. Ooids rest and accrete in the area covered by microbial mats, but are periodically transported to the surf zone where wave abrasion polishes them within days. Ooids are then transported back to microbially colonized areas where the accretion cycle resumes. Ooids too large to be transported become trapped outside the surf zone, exit the “conveyor belt” and become grapestones. The benthic growth mechanism predicts petrographic characteristics that match observations: successive ooid laminae do not thin outward, laminae exhibit irregularities, and some ooids include multiple nuclei.

The Stories We Tell: Engaging with Authority in Critical Health Pedagogy

This Innovative Practices piece details the design of a scaffolded project in a public health course that paired a narrative inquiry assignment with an empirical health literature review assignment to highlight both the positivist and constructivist epistemologies of critical health research in public health. The authors discuss and reflect on the five parts that constitute the project, student learning outcomes, and the benefits of engaging with critical information literacy in an undergraduate public health course. The goal of this article is to provide practical applications of critical information literacy to librarians in the health sciences who work with undergraduate students
