    Dialogue based interfaces for universal access.

    Get PDF
    Conversation provides an excellent means of communication for almost all people. Consequently, a conversational interface is an excellent mechanism for allowing people to interact with systems. Conversational systems are an active research area, but a wide range of systems can be developed with current technology. More sophisticated interfaces can take considerable effort, but simple interfaces can be developed quite rapidly. This paper gives an introduction to the current state of the art of conversational systems and interfaces. It describes a methodology for developing conversational interfaces and gives an example of an interface for a state benefits web site. The paper discusses how this interface could improve access for a wide range of people, and how further development of this interface would allow a larger range of people to use the system and give them more functionality

    The psychosocial environment and especially various psychosocial risks in childhood have been shown to predict later negative health behavior and health problems. In this study, we examined whether various psychosocial factor domains in childhood and adolescence: socioeconomic status, theemotional family environment (parental nurturance, life-satisfaction), parental lifestyle, life-events, the child's self-regulatory behavior and the child's social adaptation were associated with body mass index (BMI) trajectories individually by domain and as a cumulative score across domains. The participants were a nationally representative sample of 2016 men and women fromthe Young Finns study aged 3-18 years at study entry in 1980. Their BMI wasmeasured at six study phases from 1980 to 2012. Their parents reported all the factors related to their psychosocial environment in 1980. The participants responded to questions on adulthood socioeconomic status in 2007. The accumulation of psychosocial factors in childhood was the main exposure variable. The findings fromrepeated measuresmultilevelmodeling showed that parental lifestyle and life-events and the more positive cumulative psychosocial factors score were associated with a slower increase in BMI during follow-up (regression coefficient range from - 0.06 to -0.50). In conclusion, the psychosocial environment in childhood and adolescence, particularly parental lifestyle and lack of stressful life-events, are associated with a lower increase of BMI.

    Conditions for large non-Gaussianity in two-field slow-roll inflation

    Get PDF
    We study the level of primordial non-Gaussianity in slow-roll two-field inflation. Using an analytic formula for the nonlinear parameter f_nl in the case of a sum or product separable potential, we find that it is possible to generate significant non-Gaussianity even during slow-roll inflation with Gaussian perturbations at Hubble exit. In this paper we give the general conditions to obtain large non-Gaussianity and calculate the level of fine-tuning required to obtain this. We present explicit models in which the non-Gaussianity at the end of inflation can exceed the current observational bound of |f_nl|<100.Comment: 16 pages, 6 figures, 1 table, v2: typos corrected and references added, matches version accepted by JCA

    ESO Guideline on Covert Cerebral Small Vessel Disease

    Get PDF
    'Covert' cerebral small vessel disease (ccSVD) is common on neuroimaging in persons without overt neurological manifestations, and increases the risk of future stroke, cognitive impairment, dependency, and death. These European Stroke Organisation (ESO) guidelines provide evidence-based recommendations to assist with clinical decisions about management of ccSVD, specifically white matter hyperintensities and lacunes, to prevent adverse clinical outcomes. The guidelines were developed according to ESO standard operating procedures and Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. We prioritised the clinical outcomes of stroke, cognitive decline or dementia, dependency, death, mobility and mood disorders, and interventions of blood pressure lowering, antiplatelet drugs, lipid lowering, lifestyle modifications, glucose lowering and conventional treatments for dementia. We systematically reviewed the literature, assessed the evidence, formulated evidence-based recommendations where feasible, and expert consensus statements. We found little direct evidence, mostly of low quality. We recommend patients with ccSVD and hypertension to have their blood pressure well controlled; lower blood pressure targets may reduce ccSVD progression. We do not recommend antiplatelet drugs such as aspirin in ccSVD. We found little evidence on lipid lowering in ccSVD. Smoking cessation is a health priority. We recommend regular exercise which may benefit cognition, and a healthy diet, good sleep habits, avoiding obesity and stress for general health reasons. In ccSVD, we found no evidence for glucose control in the absence of diabetes or for conventional Alzheimer dementia treatments. Randomised controlled trials with clinical endpoints are a priority for ccSVD.Peer reviewe

    Wellbeing of Families in Future Europe

    Get PDF
    FAMILYPLATFORM’s aim was to develop and publish a European Research Agenda for Research on Families and Family Policy, in order to enable policy makers and others to respond to current and future challenges facing families. Four concrete steps were taken towards elaborating the Research Agenda: 1. Charting the contemporary field of research on families and family policy in the EU. 2. Critically reviewing existing research involving a wide range of stakeholders. 3. An innovative exercise to identify future challenges facing families, so as to highlight future policy issues and develop questions for future research. 4. Bringing together all of the work into a Research Agenda on Families and Family Wellbeing for Europe. Each of these areas has a dedicated chapter in this book, presenting the main results and findings of this work. More than 120 civil society representatives, policy makers, and scientific experts were involved in the work of FAMILYPLATFORM. The sharing and negotiating of sometimes contradictory perspectives and thoughts was an exciting challenge for everyone involved, resulting in a great deal of shared learning. We hope that this book passes on some of these rich experiences, thereby improving the wellbeing of families in Europe through research and policy.Wellbeing of Families in Future Europe – Challenges for Research and Policy presents the results of the FAMILYPLATFORM project, a social platform on research for families and family policy

    Positive Psychosocial Factors in Childhood Predicting Lower Risk for Adult Type 2 Diabetes : The Cardiovascular Risk in Young Finns Study, 1980-2012

    Get PDF
    Introduction: Type 2 diabetes is a public health concern, but psychosocial factors that may protect against the disease are unknown. This study examines whether a positive psychosocial environment in childhood is associated with lower risk for Type 2 diabetes in adulthood or healthier glucose trajectories over the life course, and whether BMI mediates the associations. Methods: A cohort of 3,596 Finnish children was followed into adulthood over 32 years. An overall positive psychosocial score, consisting of six subdomains, was measured at study baseline (1980). Relative risk ratios and multilevel growth curve modeling were used to examine associations of the psychosocial score with Type 2 diabetes (2012) and glucose trajectories (1986-2012). The mediating effect by BMI was examined using mediation analysis. The analyses were conducted between June 2015 and January 2016. Results: There was a 21% decrease in the rate of Type 2 diabetes (relative risk ratio, 0.79; 95% CI = 0.66, 0.94) for each 1-SD increase in the positive psychosocial score after adjustment for childhood cardiovascular risk factors and dietary behaviors. Adult BMI mediated 52% and weight gain mediated 25% of the association. The growth curve model showed healthier glucose trajectories (age X psychosocial score interaction, b = -0.01; p = 0.010) for participants with higher versus lower positive psychosocial score in childhood. Conclusions: Positive psychosocial environment in childhood seems to have beneficial influences on the risk for Type 2 diabetes over the life span. RCTs will be required to see if interventions directed at early-life circumstances are warranted. (C) 2017 American Journal of Preventive Medicine. Published by Elsevier Inc.

    Characteristics and sources of fluorescent aerosols in the central Arctic Ocean

    Get PDF
    The Arctic is sensitive to cloud radiative forcing. Due to the limited number of aerosols present throughout much of the year, cloud formation is susceptible to the presence of cloud condensation nuclei and ice nucleating particles (INPs). Primary biological aerosol particles (PBAP) contribute to INPs and can impact cloud phase, lifetime, and radiative properties. We present yearlong observations of hyperfluorescent aerosols (HFA), tracers for PBAP, conducted with a Wideband Integrated Bioaerosol Sensor, New Electronics Option during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition (October 2019–September 2020) in the central Arctic. We investigate the influence of potential anthropogenic and natural sources on the characteristics of the HFA and relate our measurements to INP observations during MOSAiC. Anthropogenic sources influenced HFA during the Arctic haze period. But surprisingly, we also found sporadic “bursts” of HFA with the characteristics of PBAP during this time, albeit with unclear origin. The characteristics of HFA between May and August 2020 and in October 2019 indicate a strong contribution of PBAP to HFA. Notably from May to August, PBAP coincided with the presence of INPs nucleating at elevated temperatures, that is, &amp;gt;−9°C, suggesting that HFA contributed to the “warm INP” concentration. The air mass residence time and area between May and August and in October were dominated by the open ocean and sea ice, pointing toward PBAP sources from within the Arctic Ocean. As the central Arctic changes drastically due to climate warming with expected implications on aerosol–cloud interactions, we recommend targeted observations of PBAP that reveal their nature (e.g., bacteria, diatoms, fungal spores) in the atmosphere and in relevant surface sources, such as the sea ice, snow on sea ice, melt ponds, leads, and open water, to gain further insights into the relevant source processes and how they might change in the future.</jats:p
