The OCarePlatform : a context-aware system to support independent living

Background: Currently, healthcare services, such as institutional care facilities, are burdened with an increasing number of elderly people and individuals with chronic illnesses and a decreasing number of competent caregivers. Objectives: To relieve the burden on healthcare services, independent living at home could be facilitated, by offering individuals and their (in)formal caregivers support in their daily care and needs. With the rise of pervasive healthcare, new information technology solutions can assist elderly people ("residents") and their caregivers to allow residents to live independently for as long as possible. Methods: To this end, the OCarePlatform system was designed. This semantic, data-driven and cloud based back-end system facilitates independent living by offering information and knowledge-based services to the resident and his/her (in)formal caregivers. Data and context information are gathered to realize context-aware and personalized services and to support residents in meeting their daily needs. This body of data, originating from heterogeneous data and information sources, is sent to personalized services, where is fused, thus creating an overview of the resident's current situation. Results: The architecture of the OCarePlatform is proposed, which is based on a service-oriented approach, together with its different components and their interactions. The implementation details are presented, together with a running example. A scalability and performance study of the OCarePlatform was performed. The results indicate that the OCarePlatform is able to support a realistic working environment and respond to a trigger in less than 5 seconds. The system is highly dependent on the allocated memory. Conclusion: The data-driven character of the OCarePlatform facilitates easy plug-in of new functionality, enabling the design of personalized, context-aware services. The OCarePlatform leads to better support for elderly people and individuals with chronic illnesses, who live independently. (C) 2016 Elsevier Ireland Ltd. All rights reserved

Home-based therapy programmes for upper limb functional recovery following stroke

Background: With an increased focus on home-based stroke services and the undertaking of programmes, targeted at upper limb recovery within clinical practice, a systematic review of home-based therapy programmes for individuals with upper limb impairment following stroke was required. Objectives: To determine the effects of home-based therapy programmes for upper limb recovery in patients with upper limb impairment following stroke. Search methods: We searched the Cochrane Stroke Group's Specialised Trials Register (May 2011), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 2), MEDLINE (1950 to May 2011), EMBASE (1980 to May 2011), AMED (1985 to May 2011) and six additional databases. We also searched reference lists and trials registers. Selection criteria: Randomised controlled trials (RCTs) in adults after stroke, where the intervention was a home-based therapy programme targeted at the upper limb, compared with placebo, or no intervention or usual care. Primary outcomes were performance in activities of daily living (ADL) and functional movement of the upper limb. Secondary outcomes were performance in extended ADL and motor impairment of the arm. Data collection and analysis: Two review authors independently screened abstracts, extracted data and appraised trials. We undertook assessment of risk of bias in terms of method of randomisation and allocation concealment (selection bias), blinding of outcome assessment (detection bias), whether all the randomised patients were accounted for in the analysis (attrition bias) and the presence of selective outcome reporting. Main results: We included four studies with 166 participants. No studies compared the effects of home-based upper limb therapy programmes with placebo or no intervention. Three studies compared the effects of home-based upper limb therapy programmes with usual care. Primary outcomes: we found no statistically significant result for performance of ADL (mean difference (MD) 2.85; 95% confidence interval (CI) -1.43 to 7.14) or functional movement of the upper limb (MD 2.25; 95% CI -0.24 to 4.73)). Secondary outcomes: no statistically significant results for extended ADL (MD 0.83; 95% CI -0.51 to 2.17)) or upper limb motor impairment (MD 1.46; 95% CI -0.58 to 3.51). One study compared the effects of a home-based upper limb programme with the same upper limb programme based in hospital, measuring upper limb motor impairment only; we found no statistically significant difference between groups (MD 0.60; 95% CI -8.94 to 10.14). Authors' conclusions: There is insufficient good quality evidence to make recommendations about the relative effect of home-based therapy programmes compared with placebo, no intervention or usual care

Does GPS supervision of intimate partner violence defendants reduce pretrial misconduct? Evidence from a quasi-experimental study

Objectives This research examines the effect global positioning system (GPS) technology supervision has on pretrial misconduct for defendants facing intimate partner violence charges. Methods Drawing on data from one pretrial services division, a retrospective quasi-experimental design was constructed to examine failure to appear to court, failure to appear to meetings with pretrial services, and rearrest outcomes between defendants ordered to pretrial GPS supervision and a comparison group of defendants ordered to pretrial supervision without the use of monitoring technology. Cox regression models were used to assess differences between quasi-experimental conditions. To enhance internal validity and mitigate model dependence, we utilized and compared results across four counterfactual comparison groups (propensity score matching, Mahalanobis distance matching, inverse probability of treatment weighting, and marginal mean weighting through stratification). Results Pretrial GPS supervision was no more or less effective than traditional, non-technology based pretrial supervision in reducing the risk of failure to appear to court or the risk of rearrest. GPS supervision did reduce the risk of failing to appear to meetings with pretrial services staff. Conclusions The results suggest that GPS supervision may hold untapped case management benefits for pretrial probation officers, a pragmatic focus that may be overshadowed by efforts to mitigate the risk of pretrial misconduct. Further, the results contribute to ongoing discussions on bail reform, pretrial practice, and the movement to reduce local jail populations. Although the cost savings are not entirely clear, relatively higher risk defendants can be managed in the community and produce outcomes that are comparable to other defendants. The results also call into question the ability of matching procedures to construct appropriate counterfactuals in an era where risk assessment informs criminal justice decision-making. Weighting techniques outperformed matching strategies

An integrated molecular and conventional breeding scheme for enhancing genetic gain in maize in Africa

Open Access Journal; Published online: 06 Nov 2019Maize production in West and Central Africa (WCA) is constrained by a wide range of interacting stresses that keep productivity below potential yields. Among the many problems afflicting maize production in WCA, drought, foliar diseases, and parasitic weeds are the most critical. Several decades of efforts devoted to the genetic improvement of maize have resulted in remarkable genetic gain, leading to increased yields of maize on farmers’ fields. The revolution unfolding in the areas of genomics, bioinformatics, and phenomics is generating innovative tools, resources, and technologies for transforming crop breeding programs. It is envisaged that such tools will be integrated within maize breeding programs, thereby advancing these programs and addressing current and future challenges. Accordingly, the maize improvement program within International Institute of Tropical Agriculture (IITA) is undergoing a process of modernization through the introduction of innovative tools and new schemes that are expected to enhance genetic gains and impact on smallholder farmers in the region. Genomic tools enable genetic dissections of complex traits and promote an understanding of the physiological basis of key agronomic and nutritional quality traits. Marker-aided selection and genome-wide selection schemes are being implemented to accelerate genetic gain relating to yield, resilience, and nutritional quality. Therefore, strategies that effectively combine genotypic information with data from field phenotyping and laboratory-based analysis are currently being optimized. Molecular breeding, guided by methodically defined product profiles tailored to different agroecological zones and conditions of climate change, supported by state-of-the-art decision-making tools, is pivotal for the advancement of modern, genomics-aided maize improvement programs. Accelerated genetic gain, in turn, catalyzes a faster variety replacement rate. It is critical to forge and strengthen partnerships for enhancing the impacts of breeding products on farmers’ livelihood. IITA has well-established channels for delivering its research products/technologies to partner organizations for further testing, multiplication, and dissemination across various countries within the subregion. Capacity building of national agricultural research system (NARS) will facilitate the smooth transfer of technologies and best practices from IITA and its partners

Evaluation of a pilot of legally assisted and supported family dispute resolution in family violence cases

Evidence of the prevalence of a history of past and/or current family violence among separated parents, and the presence of ongoing safety concerns for themselves and their children as a result of ongoing contact with the other parent, has created an impetus for the family law system to find more effective ways of dealing with families affected by family violence. In July 2009, the Federal Government announced funding for a pilot program to provide assistance, including family dispute resolution (FDR), to such families. Subsequently, Women’s Legal Service Brisbane (and other consultants) were funded by the Attorney- General’s Department (AGD) to develop a model for coordinated family dispute resolution (CFDR). CFDR is a service for separated families who need assistance to resolve parenting disputes where there has been a history of past and/or current family violence. It is being implemented in five sites/lead agencies across Australia: Perth (Legal Aid Western Australia), Brisbane (Telephone Dispute Resolution Service [TDRS], run by Relationships Australia Queensland), Newcastle (Interrelate), Western Sydney (Unifam) and Hobart (Relationships Australia Tasmania). TDRS made adaptions to the model to accommodate its telephone-based service. The pilot commenced operation at most sites in the final quarter of 2010. Implementation in one location (Brisbane) was delayed until mid-2011 to allow time to finalise the composition of the partnership. This report presents the findings of an evaluation of this process

Measuring the Use of the Active and Assisted Living Prototype CARIMO for Home Care Service Users: Evaluation Framework and Results

To address the challenges of aging societies, various information and communication technology (ICT)-based systems for older people have been developed in recent years. Currently, the evaluation of these so-called active and assisted living (AAL) systems usually focuses on the analyses of usability and acceptance, while some also assess their impact. Little is known about the actual take-up of these assistive technologies. This paper presents a framework for measuring the take-up by analyzing the actual usage of AAL systems. This evaluation framework covers detailed information regarding the entire process including usage data logging, data preparation, and usage data analysis. We applied the framework on the AAL prototype CARIMO for measuring its take-up during an eight-month field trial in Austria and Italy. The framework was designed to guide systematic, comparable, and reproducible usage data evaluation in the AAL field; however, the general applicability of the framework has yet to be validated
