Control of contagious bovine pleuropneumonia: knowledge, attitudes, perceptions and practices in Narok district of Kenya
CBPP is an important transboundary disease in sub-Saharan Africa whose control is urgent. Participatory data collection involving 52 focus group discussions in 37 village clusters and key informant interviews, a cross-sectional study involving 232 households and a post-vaccination follow up involving 203 households was carried out in 2006–2007 in Narok South district of Kenya. This was to investigate knowledge, attitudes, perceptions and practices (KAPP) associated with control of CBPP as well as the adverse post-vaccination reactions in animals in order to advice the control policy. The community perceived trans-boundary CBPP threat to their cattle. They had traditional disease coping mechanisms and were conversant with CBPP prevention and control with 49.8% (95%CI: 42.8–56.7%) giving priority to CBPP control. However, 12.9% (95%CI: 9.0–18.1%) of pastoralists had no knowledge of any prevention method and 10.0% (95%CI: 6.5–14.7%) would not know what to do or would do nothing in the event of an outbreak. Although 43.5% (95%CI: 37.1–50.2%) of pastoralists were treating CBPP cases with antimicrobials, 62.5% (95%CI: 52.1–71.7%) of them doubted the effectiveness of the treatments. Pastoralists perceived vaccination to be the solution to CBPP but vaccination was irregular due to unavailability of the vaccine. Vaccination was mainly to control outbreaks rather than preventive and exhibited adverse post-vaccination reactions among 70.4% (95%CI: 63.6–76.5%) of herds and 3.8% (95%CI: 3.5–4.2%) of animals. Consequently, nearly 25.2% (95%CI: 18.5–33.2%) of pastoralists may resist subsequent vaccinations against CBPP. Pastoralists preferred CBPP vaccination at certain times of the year and that it is combined with other vaccinations. In conclusion, pastoralists were not fully aware of the preventive measures and interventions and post-vaccination reactions may discourage subsequent CBPP vaccinations. Consequently there is need for monitoring and management of post vaccination reactions and awareness creation on CBPP prevention and interventions and their merits and demerits. CBPP vaccine was largely unavailable to the pastoralists and the preference of the pastoralists was for vaccination at specified times and vaccine combinations which makes it necessary to avail the vaccine in conformity with the pastoralists preferences. In addition, planning vaccinations should involve pastoralists and neighbouring countries. As the results cannot be generalized, further studies on CBPP control methods and their effectiveness are recommended

Impact of emotional states on the effective range of electric vehicles
Over the last decade, a large interest in reducing transportation dependence on fossil fuels as well as the cost reduction in battery technologies, have driven the electric cars market uptake. However, information is scarce about factors that affect the driving range. Besides the battery’s capacity, other factors may affect the overall vehicle’s range, for instance: driving behavior, fluctuations in temperature, number of battery cycles, etc. Accordingly, this paper proposes an approach to evaluate the impact of emotions and driving behavior on the range of electric cars using physiological signals and vehicle performance features. This work was developed in three stages. During the first stage, the heart rate and galvanic skin response of 20 volunteers were recorded from biosensors. The vehicle’s data was obtained from a driving simulator. Afterward, the driving profile was used as an input source to simulate an object-oriented electric vehicle model to estimate the driving range. Finally, during the third stage, feature selection techniques and subject-dependent classifiers were evaluated using metrics such as the accuracy and the area under the curve. Support-vector machines with radial kernel and tree-bagged models provided the best global performance with the bio-signals and driving performance subsets to discriminate between calm and aggressive driving. Results showed that driving behavior could be evaluated from physiological and vehicle features. Furthermore, the subjects’ statements showed that users’ beliefs, thoughts, and prior social contexts influence the way they perceive driving behavior. Reductions in the range of up to 68% when driving aggressively compared to a calm manner were found. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature
Detection and Analysis of ERPs for Social Cognition Evaluation
This paper describes an approach for elicitation, acquisition, and analysis of event-related potentials (ERPs) for social cognition evaluation. We used images of emotional content that were classified into three groups according to their valence: pleasant, unpleasant, and neutral. An application for stimuli generation based on the emotional oddball paradigm (EOP) was developed, and a commercial wireless EEG headset was used for signal acquisition. The ERPs of 13 volunteers for the three types of stimuli were obtained and analyzed to extract the N100 and P300 components. The results show increased amplitudes in ERP components due to unpleasant stimuli and longer latencies observed in neutral stimuli. © 2022 IEEE
Comprehensive Review of Distracted Driving Programs in the United States
With advances in technology throughout the course of time, distracted driving is at an all-time high in the United States. Even with high numbers, distraction is likely underreported because the behavior is difficult to detect during crash investigation, and police reports likely understate its incidents. According to NHTSA’s newest analysis of 2021 fatal crash data, fatalities in distraction-affected crashes increased by 12% from 2020 to 2021, a total of 8.2% of all fatalities reported. The impact of distracted driving has recently worsened. A study estimated distraction was involved in 29% of all crashes by observing driver behavior in the real world in 2019. The purpose of this study is 1) to understand the safety performance of distracted driving in the State of Florida; 2) to investigate state laws across the nation to understand the policies and programs that combat distracted driving
Peptide-Based Scaffolds Support Human Cortical Progenitor Graft Integration to Reduce Atrophy and Promote Functional Repair in a Model of Stroke
Stem cell transplants offer significant hope for brain repair following ischemic damage. Pre-clinical work suggests that therapeutic mechanisms may be multi-faceted, incorporating bone-fide circuit reconstruction by transplanted neurons, but also protection/regeneration of host circuitry. Here, we engineered hydrogel scaffolds to form "bio-bridges" within the necrotic lesion cavity, providing physical and trophic support to transplanted human embryonic stem cell-derived cortical progenitors, as well as residual host neurons. Scaffolds were fabricated by the self-assembly of peptides for a laminin-derived epitope (IKVAV), thereby mimicking the brain's major extracellular protein. Following focal ischemia in rats, scaffold-supported cell transplants induced progressive motor improvements over 9 months, compared to cell- or scaffold-only implants. These grafts were larger, exhibited greater neuronal differentiation, and showed enhanced electrophysiological properties reflective of mature, integrated neurons. Varying graft timing post-injury enabled us to attribute repair to both neuroprotection and circuit replacement. These findings highlight strategies to improve the efficiency of stem cell grafts for brain repair

Engagement intervention versus treatment as usual for young adults with serious mental illness: a randomized pilot trial
Background: Young adults have elevated rates of mental health disorders, yet they often do not receive consistent care. The challenge of continuing to engage young adults has been pervasive worldwide. Few engagement interventions have been designed for young adults with serious mental illness. Just Do You is a theoretically guided engagement intervention. It uses innovative modalities (i.e., technology, expressive arts activities, narrative expression, mentoring) to engage participants in conversations about services and how they work, while simultaneously orienting them to treatment.
Methods/design: This pilot and feasibility study utilizes a hybrid research design, examining feasibility, acceptability, and preliminary impact, alongside implementation. The study combines qualitative methods, a small pilot randomized trial, and a small cost-benefit analysis. Respondents are clinic staff and young adults who have made initial contact with the Personalized Recovery Oriented Services (PROS) program. Quantitative survey data are collected at baseline, 2 weeks (post-intervention), 1 month, and 3 months. The assessments focus on measuring feasibility, acceptability, engagement, and mental health outcomes. Medical record extraction will be used to triangulate self-report data. We will conduct single degree of freedom contrasts to examine whether Just Do You leads to improved outcomes relative to Treatment-As-Usual using robust regression for each outcome measure. We will examine whether changes in the proposed mediating variables occur across groups using a similar contrast strategy. In addition, we will use structural equation modeling to examine the contribution of mediators to ultimate outcomes. Finally, we will use constant comparison coding techniques for qualitative analyses.
Discussion: The aim of this study is to examine the feasibility of a young adult engagement meta-intervention through an intensive preliminary pilot trial, learning through collaboration with stakeholders. Just Do You has the potential to fill a gap in the service system for young adults with serious mental illnesses, improving the seemingly intractable problem of disengagement. The program uses culturally responsive strategies, is recovery-oriented, and builds upon the best evidence to date. Our efforts align with local and national health care reform efforts embedding people with lived experience.
Trial registration: This trial was registered with ClinicalTrials.gov (Identifier: NCT03423212) on April 18, 2018, as Protocol Record R34 MH111861-01, New York University, as the Just Do You Program for Young Adults with Serious Mental Illness
