With the increasing prevalence of portable devices and the popularity of community Question Answering (cQA) sites, users can seamlessly post and answer many questions. To effectively organize the information for precise recommendation and easy searching, these platforms require users to select topics for their raised questions. However, due to the limited experience, certain users fail to select appropriate topics for their questions. Thereby, automatic question tagging becomes an urgent and vital problem for the cQA sites, yet it is non-trivial due to the following challenges. On the one hand, vast and meaningful topics are available yet not utilized in the cQA sites; how to model and tag them to relevant questions is a highly challenging problem. On the other hand, related topics in the cQA sites may be organized into a directed acyclic graph. In light of this, how to exploit relations among topics to enhance their representations is critical. To settle these challenges, we devise a graph-guided topic ranking model to tag questions in the cQA sites appropriately. In particular, we first design a topic information fusion module to learn the topic representation by jointly considering the name and description of the topic. Afterwards, regarding the special structure of topics, we propose an information propagation module to enhance the topic representation. As the comprehension of questions plays a vital role in question tagging, we design a multi-level context-modeling-based question encoder to obtain the enhanced question representation. Moreover, we introduce an interaction module to extract topic-aware question information and capture the interactive information between questions and topics. Finally, we utilize the interactive information to estimate the ranking scores for topics. Extensive experiments on three Chinese cQA datasets have demonstrated that our proposed model outperforms several state-of-the-art competitors.

Abstract Background Andexanet alfa (andexanet) is approved for specific anticoagulation reversal in patients with life-threatening or uncontrolled bleeding during treatment with rivaroxaban or apixaban. There is limited experience with andexanet in patients with acute bleeding on edoxaban. Methods Patients with acute major bleeding within 18 hours of edoxaban intake were prospectively enrolled. Patients received a bolus and 2-hour follow-on infusion of andexanet. The co-primary efficacy outcomes were change in antifactor Xa activity and the percentage of patients achieving excellent or good hemostasis, 12 hours after andexanet treatment. Efficacy was analyzed in patients with confirmed major bleeding and baseline antifactor Xa activity ≥40 ng/mL. Safety was analyzed in all patients. Results Thirty-six patients (mean age: 82 years, 61.1% male and 91.7% with atrial fibrillation) with acute major bleeding on edoxaban received andexanet. The primary site of bleeding was intracranial in 29 patients (80.6%). In the efficacy population (n = 28), median antifactor Xa activity decreased from 121.1 (interquartile range [IQR]: 70.3–202.4) ng/mL at baseline to 24.0 (IQR: 77.7–83.7) ng/mL at the end of andexanet bolus (median decrease: 68.9%, 95% confidence interval [CI]: 56.1–77.7%). Excellent or good hemostasis at 12 hours was achieved in 78.6% (95% CI: 59.0–91.7%) of patients. Within 30 days, four patients (11.1%) experienced a thrombotic event and four others (11.1%) died. Conclusion In patients with acute major bleeding on edoxaban, andexanet significantly decreased antifactor Xa activity. Hemostatic efficacy was similar to that observed in patients with bleeding on rivaroxaban or apixaban. Thrombotic events occurred at a rate expected in such patients.

The article examines the controversial procedure of analyzing the learner’s professional needs. Needs analysis is generally regarded as an invaluable tool for constructing a course syllabus. It might be really informative if the target situation analysis and present situation analysis are combined. Speaking about academic writing teaching for Russian non-academic students at the Bachelor Degree level, one should admit that students have no or limited experience of functioning in an academic area in English. Consequently, their responses to the questionnaires as one of the frequently used methods of target situation analysis are merely assumptions; and the answers could not be taken as objective and valid. The author presents a system of analyzing students’ needs within the framework of Academic Writing course: namely, distinguishes the stages that precede or follow teacher-student talks about their expectations, provides more objective practice of examining learners’ needs, and discusses ways of improving question-answer sessions/ interviews. Needs analysis practice that develops learners’ professional needs involves task-based learning, reflexive activities, and teaching to ask good questions. Bringing into life the analogy between customer development theory in management and needs analysis practice in education, it is possible to work out a fruitful strategy. Conducting needs analysis pertains equally to specifying and developing students’ needs in academic communication.

The purpose of this study was to evaluate the difficulties faced by LH students of dental faculty and the effect of their training program on the musculo-skeletal system. A survey of 11 questions was used to get the necessary data for further analysis. The results of the study showed that the percentage of LH students in the faculty is 7.32 percent (40 of 546). The prevalence of left-handedness of males (9.59%) is higher than that of females (6.03%). The majority of LH students (85%) confirmed that their sinistrality is of no significance in their life organization. LH students neglect that their sinistrality has a significant effect on their dental practice, this is due to their limited experience in practice. The majority of the LH students (85%) prefer using special dental units designed to fit their needs. 35% of the students approved that they started experiencing symptoms of MSDs during their practical phase of studies. The results of this study suggest that LH dental students require special educational atmosphere which would yield in a more professional undergraduates with high efficiency in the work field.

Globally, financing healthcare is one of the biggest challenges and it becomes a life or death issue in poor countries. Nepal is strongly committed to universal health coverage and Sustainable Development Goals. Existing public health services are inadequate to cater to the growing demands of quality health care and Public Private Partnership (PPP) evolved as newer arrangement for robust healthcare system, improved healthcare quality and enhance cost-effectiveness. Nepal has successfully utilized the PPP model in multiple sectors, however there is limited experience in healthcare. Strengthening PPP models in healthcare  could be the pathway for Nepal toward SDG’s and UHC achievement.

Purpose The purpose of this paper is to introduce the current state of education in the field of social enterprise in Slovakia and its support, share the experience of social entrepreneurship education providers and formulate recommendations for the development of human resources in the context of supporting social enterprise. Design/methodology/approach This paper is presented as a case study. It is based on the initial experience of education providers in the field of social entrepreneurship in Slovakia, as the concept of integrating social entrepreneurship into education in Slovak conditions is currently in the phase of gradual establishment. Findings One of the biggest barriers of the development of education is insufficient awareness and overall promotion of social enterprise in Slovakia. The general public lacks awareness on the topic of social enterprise and a general platform on social enterprise, which would provide information on the possibilities of formal and non-formal education, is missing. Research limitations/implications The findings of this paper are based on the limited experience of social entrepreneurship education providers, as the systematic concept of integrating social entrepreneurship into education in Slovak conditions is currently in the phase of gradual establishment. Originality/value To the best of the authors’ knowledge, this is the first study, which provides an overview of the present situation of education in the field of social enterprise from the perspective of the experience of the addressed organizations, their opinions and perception.

The purpose of this study was to determine the differences in human stepping response reaction between constrained and unconstrained standing while being exposed to simulated wave-induced platform motions. Twenty subjects (10 male and 10 female), with limited experience recreating or working in motion-rich environments, performed a constrained and an unconstrained standing task on a six-degrees-of-freedom motion bed while being exposed to two different simulated platform motion conditions. Stepping occurrence was greater during unconstrained standing than constrained standing during all three motion conditions. However, no significant differences in platform kinematics were found between stepping cases. These results suggest that stepping occurs more frequently than originally hypothesized. As such, stepping should not be considered as a last resource when all fixed-support options have been exhausted. This should be taken into consideration to ensure ecological validity when developing models to predict stepping occurrence.

Recent guidelines recommend the umbilical venous catheter (UVC) as the optimal vascular access method during neonatal resuscitation. In emergencies the UVC securement may be challenging and time-consuming. This experimental study was designed to test the feasibility of new concepts for the UVC securement. Umbilical cord remnants were catheterized with peripheral catheters and secured with disposable umbilical clamps. Three different securement techniques were investigated. Secure 1: the disposable umbilical clamp was closed at the level of the inserted catheter. Secure 2: the clamp was closed at the junction of the catheter and plastic wings. Secure 3: the setting of Secure 2 was combined with an umbilical tape. The main outcomes were the feasibility of fluid administration and the maximum force to release the securement. This study shows that inserting peripheral catheters into the umbilical vein and securing them with disposable umbilical clamps is feasible. Rates of lumen obstruction and the effectiveness of the securement were superior with Secure 2 and 3 compared to Secure 1. This new approach may be a rewarding option for umbilical venous catheterization and securement particularly in low-resource settings and for staff with limited experience in neonatal emergencies. However, although promising, these results need to be confirmed in clinical trials before being introduced into clinical practice.

This teaching case focuses on corporate entrepreneurship and collaborative innovation during an unprecedented crisis – the shortage in mechanical ventilators when the Covid-19 pandemic began. Based on secondary data sources, the case outlines the challenges of designing and manufacturing mechanical ventilators and introduces four initiatives, consisting of organisations with often limited experience in medical device manufacturing that attempted to address the predicted shortage of ventilators. By comparing the approaches used in these initiatives, the case sensitises students to the challenges of pursuing opportunities outside a firm's established domain of expertise and how inter-organisational collaboration affects such attempts. Although the case centres on an unprecedented event, the insights it develops make it suitable for a range of innovation and entrepreneurship-related under- and post-graduates courses.

In Physical Education, there is a discussion about the theory and practice dichotomy, and how much one provides support to the other to obtain legitimacy. This leads to thinking about the training of the new professionals in the area. In the training environment, there are theoretical subjects, which seem to be far from a reality outside of the university. This causes a misinterpretation of the real situation of education. The aim of this study was to verify the perception of the scholarship students about the extension Project “The insertion of the university in soccer” regarding the dimension theory and practice in the Physical Education training. It was conducted qualitative research, with a qualitative approach, and composed of five scholarship students from the extension project. The data were collected through an open questionnaire, applied to the students, and analyzed with the theoretical framework searching for the results. The data analysis indicates the tension maintenance between theory and practice, which the first one concentrates on the setting of a conceptual framework far from the practice conceived as a limited “experience of yourself” during an educational activity. However, the extensionists practices allowed to widen the knowledge of the professional expertise and, paradoxically, the application of the theories learned in the academic environment.
