This paper presents experimental results of investigations on narrowband Internet of Things (NB-IoT) uplink channel performance under extreme pathloss conditions, approaching the boundary maximum coupling loss (MCL) defined for cellular IoT systems. The system performance was systematically tested against several modulation coding schemes (MCSs) and a set of repetition numbers (Nrep) in electromagnetically isolated facilities, guaranteeing proper environment separation from external factors that usually affect measurements in less controlled setups. Some of the major takeaways include the following observations. Firstly, every increase in the number of repetitions by a factor of four caused the performance to improve by about 3 dB. Secondly, the switchover between extreme MCSs (i.e., MCS0 and MCS10) caused the performance to shift by about 6 dB. Thirdly, chipsets from different vendors performed similarly at small values of Nrep, but tended to diverge for larger numbers of repetitions. These findings may serve as benchmark figures for other theoretical and simulation-based studies by demonstrating performance in response to Nrep and MCSs for a vast scope of their values. Future investigations will concern the impact of multipath channels, typical in real-life deployment scenarios.

Abstract Background Lumbar puncture (LP) is an invasive medical procedure that can be done by any doctor. Several simulation-based trainings have been built however the evaluations of the theoretical knowledge and the impact of the simulation-based training have never been performed in real life. The objective was to evaluate the impact of a LP training on the theoretical knowledge improvement and the performance of a LP in clinical practice. Methods Before and after medical students’ training, theoretical knowledge and confidence level were assessed. Over a 6 months period, the impact of simulation training was evaluated by the success rate of students’ first LP carried out in hospitalized patients and compared to the results of a no-training control. Results Students’ theoretical knowledge and confidence level showed significant improvement after simulation training on 115 students (p < 0.0001). The evaluation in real life based on 41 students showed that the success rate of the first LP in patients was higher in the LP simulation group compared to the control group (67% vs 14%, p = 0.0025). The technical assistance was also less frequently needed in the LP simulation group (19% vs 57%, respectively, p = 0.017). The rate of students who participated in this educational study was low. Discussion Simulation-based teaching was an effective way to improve students’ theoretical and practical knowledge. Whether this approach translates to other procedural skills in real clinical settings merits further study. The low participation rate in the study is due to the fact that students are not used to be included in educational studies and to the complexity of evaluation in routine clinical practice.

The Impact

Every year, countless projects are finished late, go over budget or end up being cancelled, often because their project managers and project teams lack the necessary tools and techniques to support their decision-making. Students of project management courses around the world have difficulty integrating the different knowledge areas of project management, after studying each knowledge area separately. Students then struggle and even fail when it comes to applying these concepts in a real-life project. Simulation-based training contributes to the solution of these problems by linking the concepts learned during a project management course and providing the experience of managing a simulated project that serves as preparation for real life. The objective of this research is to study the impact of simulation-based training and flipped classroom methodology on students learning project management. The contribution of this research is twofold. First, from a theoretical perspective, simulation-based training and flipped classroom methodology literature is enriched and broadened by applying both teaching tools. Second, from a practical perspective, an improvement in results, satisfaction and lessons learned was found when using simulation-based training under flipped classroom methodology compared to simulation-based training in a traditional classroom.

AbstractNegative psychosocial consequences have been reported for children with auditory processing disorder (APD). The current literature surrounding APD does not sufficiently address the emotional and psychological consequences of living with the disorder. It is recommended that data be collected from multiple sources, including the child living with APD. Subjective reports of the perceptions of children with APD and their families have real-life validity and can inform clinical decisions and guide future research.The aims of this study were to explore the psychosocial consequences of APD as perceived by children with the disorder and their parents.Qualitative cross-sectional study.Thirteen participants were interviewed: six children with APD, aged 10–12 yr, and one parent for each child (in one case, two parents participated in the interview).Semistructured interviews were used to examine the social, emotional, and educational well-being of children with APD. Inductive thematic analysis was conducted to develop themes that illustrated the experiences of living with APD.Three themes were identified forming a causal network conceptual framework that is reciprocal in nature: (1) external factors, (2) internal problems, and (3) coping. The themes revealed how APD impacted negatively on children’s psychosocial well-being (internal problems: covert thoughts, overt behaviors) and described the basis for these outcomes (external factors: environmentally based problems, dissatisfaction with support) and the ability of children and their parent(s) to manage the impact of APD (coping: positive, negative).The three themes identified in this research provide a novel understanding of the experience of APD. The themes reflect the psychosocial consequences of external factors that are created internally through “thought” and expressed externally through “behavior.” Pathways to support positive coping strategies while discouraging negative coping strategies will enable children to overcome problems and improve their psychosocial well-being.

Orthogonal Frequency Division Multiplexing (OFDM) offers several benefits such as flexible wrapping, mail sign interference, reduced complexity and more. The only way to match parallel channels is to have genetic diversity in multipath channels. Various coded of OFDM systems reported using some form of channel coding or pre-coding to improve system performance. The execution of irrational orthogonal frequency division multiplexing (OFDM) on blurred channels is usually better than introducing some coding. Various coding schemes for off-OFDM have been reported in the literature.

The Impact

It is widely recognised that hypertension is a major risk factor for the development of future cardiovascular (CV) events, which in turn are a major cause of morbidity and mortality. Blood pressure (BP) control with antihypertensive drugs has been shown to reduce the risk of CV events. Angiotensin-II receptor blockers (ARBs) are one such class of antihypertensive drugs and randomised controlled trials (RCTs) have shown ARB-based therapies to have effective BP-lowering properties. However, data obtained under these tightly controlled settings do not necessarily reflect actual experience in clinical practice. Real-life databases may offer alternative information that reflects an uncontrolled real-world setting and complements and expands on the findings of clinical trials. Recent analyses of practice-based real-life databases have shown ARB-based therapies to be associated with better persistence and adherence rates and with superior BP control than non-ARB-based therapies. Analyses of real-life databases also suggest that ARB-based therapies may be associated with a lower risk of CV events than other antihypertensive-drug-based therapies.

Cognition And Affect

This survey of research on psychology in five volumes is a part of a series undertaken by the ICSSR since 1969, which covers various disciplines under social science. Volume One of this survey, Cognitive and Affective Processes, discusses the developments in the study of cognitive and affective processes within the Indian context. It offers an up-to-date assessment of theoretical developments and empirical studies in the rapidly evolving fields of cognitive science, applied cognition, and positive psychology. It also analyses how pedagogy responds to a shift in the practices of knowing and learning. Additionally, drawing upon insights from related fields it proposes epithymetics–desire studies – as an upcoming field of research and the volume investigates the impact of evolving cognitive and affective processes in Indian research and real life contexts. The development of cognitive capability distinguishes human beings from other species and allows creation and use of complex verbal symbols, facilitates imagination and empowers to function at an abstract level. However, much of the vitality characterizing human life is owed to the diverse emotions and desires. This has made the study of cognition and affect as frontier areas of psychology. With this in view, this volume focuses on delineating cognitive scientific contributions, cognition in educational context, context, diverse applications of cognition, psychology of desire, and positive psychology. The five chapters comprising this volume have approached the scholarly developments in the fields of cognition and affect in innovative ways, and have addressed basic as well applied issues.
