Effectiveness of the ADEC as a level 2 screening test for young children with suspected autism spectrum disorders in a clinical setting
Background The Autism Detection in Early Childhood (ADEC) is a clinician-administered, Level 2 screening tool. A retrospective file audit was used to investigate its clinical effectiveness.
Method Toddlers referred to an Australian child development service between 2008 and 2010 (N?=?53, M age?=?32.2 months) were screened with the ADEC. Their medical records were reviewed in 2013 when their mean age was 74.5 months, and the original ADEC screening results were compared with later diagnostic outcomes.
Results The ADEC had good sensitivity (87.5%) and moderate specificity (62%). Three behaviours predicted autism spectrum disorders (ASDs): response to name, gaze switching, and gaze monitoring (p???.001).
Conclusions The ADEC shows promise as a screening tool that can discriminate between young children with ASDs and those who have specific communication disorders or developmental delays that persist into middle childhood but who do not meet the criteria for ASDs
Unrestricted Hartree-Fock theory of Wigner crystals
We demonstrate that unrestricted Hartree-Fock theory applied to electrons in
a uniform potential has stable Wigner crystal solutions for in
two dimensions and in three dimensions. The correlation energies
of the Wigner crystal phases are considerably smaller than those of the fluid
phases at the same density.Comment: 4 pages, 5 figure
Microwave saturation of the Rydberg states of electrons on helium
We present measurements of the resonant microwave excitation of the Rydberg
energy levels of surface state electrons on superfluid helium. The temperature
dependent linewidth agrees well with theoretical predictions and is very small
below 300 mK. Absorption saturation and power broadening were observed as the
fraction of electrons in the first excited state was increased to 0.49, close
to the thermal excitation limit of 0.5. The Rabi frequency was determined as a
function of microwave power. The high values of the ratio of the Rabi frequency
to linewidth confirm this system as an excellent candidate for creating qubits.Comment: 4 pages, 4 figure
The place of strategic environmental assessment in the privatised electricity industry
The private sector has given relatively little attention to the emergence of strategic environmental assessment (SEA); even recently privatised utilities, where SEA might be deemed particularly appropriate, and whose activities are likely to fall within the scope of the European Union SEA Directive, have shown less interest than might be expected. However, the global trend towards the privatisation of state-owned enterprises makes the adaptation of SEA towards these industries all the more pressing. This paper addresses the place that SEA might take within the electricity sector, taking the privatised UK electricity industry as an example. Particular challenges are posed by the radical restructuring of the industry, designed to introduce competitive behaviour, making the development of comprehensive SEA processes problematic, and requiring SEA to be placed in the context of corporate environmental policy and objectives.</p
Stable sulforaphane protects against gait anomalies and modifies bone microarchitecture in the spontaneous STR/Ort model of osteoarthritis
Osteoarthritis (OA), affecting joints and bone, causes physical gait disability with huge socio-economic burden; treatment remains palliative. Roles for antioxidants in protecting against such chronic disorders have been examined previously. Sulforaphane is a naturally occurring antioxidant. Herein, we explore whether SFX-01®, a stable synthetic form of sulforaphane, modifies gait, bone architecture and slows/reverses articular cartilage destruction in a spontaneous OA model in STR/Ort mice. Sixteen mice (n = 8/group) were orally treated for 3 months with either 100 mg/kg SFX-01® or vehicle. Gait was recorded, tibiae were microCT scanned and analysed. OA lesion severity was graded histologically. The effect of SFX-01® on bone turnover markers in vivo was complemented by in vitro bone formation and resorption assays. Analysis revealed development of OA-related gait asymmetry in vehicle-treated STR/Ort mice, which did not emerge in SFX-01®-treated mice. We found significant improvements in trabecular and cortical bone. Despite these marked improvements, we found that histologically-graded OA severity in articular cartilage was unmodified in treated mice. These changes are also reflected in anabolic and anti-catabolic actions of SFX-01® treatment as reflected by alteration in serum markers as well as changes in primary osteoblast and osteoclast-like cells in vitro. We report that SFX-01® improves bone microarchitecture in vivo, produces corresponding changes in bone cell behaviour in vitro and leads to greater symmetry in gait, without marked effects on cartilage lesion severity in STR/Ort osteoarthritic mice. Our findings support both osteotrophic roles and novel beneficial gait effects for SFX-01® in this model of spontaneous OA
The moral-IT deck:A tool for ethics by design
This paper presents the design process and empirical evaluation of a new tool
for enabling ethics by design: The Moral-IT Cards. Better tools are needed to
support the role of technologists in addressing ethical issues during system
design. These physical cards support reflection by technologists on normative
aspects of technology development, specifically on emerging risks, appropriate
safeguards and challenges of implementing these in the system. We discuss how
the cards were developed and tested within 5 workshops with 20 participants
from both research and commercial settings. We consider the role of
technologists in ethics from different EU/UK policymaking initiatives and
disciplinary perspectives (i.e. Science and Technology Studies (STS), IT Law,
Human Computer Interaction (HCI), Computer/Engineering Ethics). We then examine
existing ethics by design tools, and other cards based tools before arguing why
cards can be a useful medium for addressing complex ethical issues. We present
the development process for the Moral-IT cards, document key features of our
card design, background on the content, the impact assessment board process for
using them and how this was formulated. We discuss our study design and
methodology before examining key findings which are clustered around three
overarching themes. These are: the value of our cards as a tool, their impact
on the technology design process and how they structure ethical reflection
practices. We conclude with key lessons and concepts such as how they level the
playing field for debate; enable ethical clustering, sorting and comparison;
provide appropriate anchors for discussion and highlighted the intertwined
nature of ethics.Comment: Governance and Regulation; Design Tools; Responsible Research and

Development, implementation, and evaluation of the Apollo model of pediatric rehabilitation service delivery
This article presents the experience of a rehabilitation program that un-
dertook the challenge to reorganize its services to address accessibility issues and im-
prove service quality. The context in which the reorganization process occurred, along
with the relevant literature justifying the need for a new service delivery model, and
an historical perspective on the planning; implementation; and evaluation phases of the
process are described. In the planning phase, the constitution of the working committee,
the data collected, and the information found in the literature are presented. Apollo, the
new service delivery model, is then described along with each of its components (e.g.,
community, group, and individual interventions). Actions and lessons learnt during the
implementation of each component are presented. We hope by sharing our experiences
that we can help others make informed decisions about service reorganization to im-
prove the quality of services provided to children with disabilities, their families, and
their communities
The TARGET_TIA: A complete, flexible and sound territorial impact assessment tool
This chapter presents TARGET_TIA as a relevant and flexible Territorial Impact Assessment (TIA) methodology. TARGET_TIA was created in a context where existing ESPON TIA tools were mainly designed for assessing ex ante territorial impacts of EU directives. Hence, in view of the need to properly assess the main ex post territorial impacts of EU Cohesion Policy in several countries in a relevant and sound way, the author decided to design, test and apply his own TIA methodology, named TARGET_TIA. When compared with other existing TIA methodologies, TARGET_TIA can be used both at ex ante and ex post policy evaluation phases. In addition, it brings to the table the possibility to use counterfactual evaluation elements to allow the production of credible and sound TIA evaluation scores. Following on from its implementation in assessing the main territorial impacts of EU policies and programmes, mostly at the ex post evaluation phase, it is possible to conclude that it is a credible, flexible, easy-to-operate, cost-effective and robust TIA methodology, which can be applied to projects, programmes and policies, at all territorial levels.info:eu-repo/semantics/acceptedVersio
The microRNA-29 family in cartilage homeostasis and osteoarthritis
MicroRNAs have been shown to function in cartilage development and homeostasis, as well as in progression of osteoarthritis. The objective of the current study was to identify microRNAs involved in the onset or early progression of osteoarthritis and characterise their function in chondrocytes. MicroRNA expression in mouse knee joints post-DMM surgery was measured over 7 days. Expression of miR-29b-3p was increased at day 1 and regulated in the opposite direction to its potential targets. In a mouse model of cartilage injury and in end-stage human OA cartilage, the miR-29 family were also regulated. SOX9 repressed expression of miR-29a-3p and miR-29b-3p via the 29a/b1 promoter. TGFβ1 decreased expression of miR-29a, b and c (3p) in primary chondrocytes, whilst IL-1β increased (but LPS decreased) their expression. The miR-29 family negatively regulated Smad, NFκB and canonical WNT signalling pathways. Expression profiles revealed regulation of new WNT-related genes. Amongst these, FZD3, FZD5, DVL3, FRAT2, CK2A2 were validated as direct targets of the miR-29 family. These data identify the miR-29 family as microRNAs acting across development and progression of OA. They are regulated by factors which are important in OA and impact on relevant signalling pathways
