How to teach fully illiterate adults to read.
About 750 million adults (15%) worldwide lack any literacy skills, most because they lack adequate learning opportunities (UNESCO, 2016). In this chapter, we discuss how to teach to read to such people. We first examine scientific evidence suggesting that literacy acquisition does not radically differ as a function of age of acquisition. We then discuss the data relevant for designing effective methods aimed at teaching literacy to fully illiterate adults. We argue that the available adult data confirm those relative to teaching methods and learning processes that have been gathered on literacy acquisition by children. On the basis of those works we propose principles that should underlie any method aiming at rapidly developing basic literacy skills. Lastly, we present evidence (Kolinsky, Leite, Carvalho, Franco, & Morais, submitted) suggesting that implementing these principles does indeed allow teaching illiterate adults to decode words and pseudo-words in a very short period of time
Empirical Study of Ground Proximity Effects for Small-scale Electroaerodynamic Thrusters
Electroaerodynamic (EAD) propulsion, where thrust is produced by collisions
between electrostatically-accelerated ions and neutral air, is a potentially
transformative method for indoor flight owing to its silent and solid-state
nature. Like rotors, EAD thrusters exhibit changes in performance based on
proximity to surfaces. Unlike rotors, they have no fragile and quickly spinning
parts that have to avoid those surfaces; taking advantage of the efficiency
benefits from proximity effects may be a route towards longer-duration indoor
operation of ion-propelled fliers. This work presents the first empirical study
of ground proximity effects for EAD propulsors, both individually and as
quad-thruster arrays. It focuses on multi-stage ducted centimeter-scale
actuators suitable for use on small robots envisioned for deployment in
human-proximal and indoor environments. Three specific effects (ground,
suckdown, and fountain lift), each occurring with a different magnitude at a
different spacing from the ground plane, are investigated and shown to have
strong dependencies on geometric parameters including thruster-to-thruster
spacing, thruster protrusion from the fuselage, and inclusion of flanges or
strakes. Peak thrust enhancement ranging from 300 to 600% is found for certain
configurations operated in close proximity (0.2 mm) to the ground plane and as
much as a 20% increase is measured even when operated centimeters away
Child-Abuse-Related-Deaths, Child Mortality (0-4) & Income Inequality in America and Other Developed Nations 1989-91 v 2012-14: Speaking Truth to Power.
The major concern for social work, namely child abuse‐related deaths (CARD), involves parental neglect. Societal neglect, when measured by child mortality rates (CMR), is considered by bodies such as UNICEF to be indicative of how a nation meets the needs of its children. This population‐based study analyses CARD and CMR for children aged from newborn to four years old between 1989–91 and 2013–15 to identify any relative child neglect in the USA and 20 other developed nations (ODN).
World Health Organization data were used for CARD, CMR and undetermined deaths (UnD), a possible source of unreported CARD, juxtaposed against World Bank income inequality data.
The USA had the highest number of CARD, the highest CMR and the worst income inequality. Five countries reduced their CARD significantly more than the USA, and 14 countries reduced their CMR more than the USA. Income inequality and CMR were correlated.
Had the USA matched the CMR of Japan, where income inequality was narrowest, there would have been on average 16 745 fewer child deaths annually.
CARD and UnD correlated, suggesting that UnD may contain unreported CARD. US CMR data indicate that services in the USA are less effective than those in ODN, possibly due to income inequality. These results will be unwelcome but child protection services must dare to speak truth to power.
‘This population‐based study analyses CARD and CMR for children aged from newborn to four years old between 1989–91 and 2013–15 to identify any relative child neglect in the USA and 20 other developed nations’
Key Practitioner Messages
The richest country in the world, the USA, has the highest rates of child abuse and total child mortality in the Western world.
The USA has the highest income inequality in the West, highlighting the statistical link between child mortality and poverty.
Children's services should lead the call for the necessary changes and ‘speak truth to power’

Rereading the Universal Declaration of Human Rights: plurality and contestation, not consensus
In this paper I examine the drafting of the Universal Declaration of Human Rights. My analysis counters conventional narratives of consensus and imposition that characterize the development of the UN human rights regime. The central argument is that within the founding text of the contemporary human rights movement there is an ambiguous account of rights, which exceeds easy categorization of international rights as universal moral principles or merely an ideological imposition by liberal powers. Acknowledging this ambiguous history, I argue, opens the way to an understanding of human rights as an ongoing politics, a contestation over the terms of legitimate political authority and the meaning of “humanity” as a political identity
Values of sexual behaviour in Central and Eastern Europe
Despite the profusion of social cognitive models for the prediction of sexual behaviour, we have only limited knowledge as to the role of individual values in predicting risky sexual activity. This study assessed the relationship between a recently developed value structure and sexual behaviour in the context of rising HIV infection in central and eastern Europe. Five hundred and three respondents (business people, doctors and nurses) from Estonia, Georgia, Hungary, Poland and Russia completed Schwartz’s Portrait Values Questionnaire and reported their condom use, partnership history and record of sexual disease. Results indicated that values had a moderate but consistent relationship with sexual behaviour, with riskier sexual activity reported by those high on Openness to Change, Hedonism and Self-Enhancement. These findings are discussed in the context of the need for culturally sensitive interventions in order to tackle the growing HIV epidemic in this region.This project was supported by a research grant from the Research Support Scheme operated by the Soros Foundation, Prague
Capacity Gaps in Post Disaster Waste Management: Case Study in Sri Lanka
Disaster waste is one of the major consequences aftermath of any disaster, impacts on public and environment, rescue and emergency services, provision of lifeline support and socio-economic recovery of affected areas. Thus, management of wastes created by disasters has become an increasingly important issue to be addressed in responding to a disaster. This chapter intends to present the prevailing gaps in disaster waste management and approaches to minimize the impacts on disaster management at developing countries with special emphasis to Sri Lankan context. Findings revealed that, unavailability of single point responsibility and provisions for disaster waste in existing policies and capacity constraints of the prevailing peace time solid waste management practices as major capacity gaps. Establishment of a regulatory body and enforceable rules and regulations with necessary levels of capacities were identified with seven areas for capacity building for post disaster waste management. The research enabled to attain sustainable post disaster waste management for future resilience
Ecofeminism in the 21st Century
This paper considers the influence of ecofeminism on policy concerning gender (in)equality and the environment during the past 20 years. It reviews the broad contours of the ecofeminist debate before focusing on the social construction interpretation of women's relationship with the environment. It will argue that there have been substantial policy shifts in Europe and the UK in both the environmental and equalities fields, and that this is in part a result of lobbying at a range of scales by groups informed by ecofeminist debates. Nevertheless, the paper cautions that these shifts are largely incremental and operate within existing structures, which inevitably limit their capacity to create change. As policy addresses some of the concerns highlighted by ecofeminism, academic discourse and grass roots activity have been moving on to address other issues, and the paper concludes with a brief consideration of contemporary trajectories of ecofeminism and campaigning on issues that link women's, feminist and environment concerns
Induced Pluripotent Stem Cell-based in vitro Modeling of the Osteogenesis and Chondrogenesis of Juvenile Osteochondritis Dissecans
The application of pluripotent stem-cell based in vitro models has become increasingly popular in medical research, especially for situations in which animal modeling is not sufficient to accurately describe the condition or for diseases where there is little research demonstrating the relationships between disease phenotype, pathological cellular mechanisms, and gene expression. Such is the case with Juvenile Osteochondritis Dissecans (JOCD), a degenerative bone disease that predominately affects the knee joints of children and progresses to early onset osteoarthritis. Previous research has involved the use of animal models or diseases similar to JOCD, but there has been little to no focus on the cellular mechanisms of this condition. Therefore, this study aimed to elucidate the cellular pathophysiology of JOCD as well as provide a test bed for future therapeutic interventions. We hypothesized that our iPSC in vitro models of JOCD would show protein dysfunction and accumulation in the rough endoplasmic reticulum as a hallmark of the disease, as previously shown in familial and equine OCD.Undergraduat
