Application of reduced sensor movement sequences as a precursor for search area partitioning and a selection of discrete EEV contour-ring fragments for active electrolocation.

In addition to their visual sense, weakly electric fish use active electrolocation to detect and analyse objects in their nearby environment. Their ability to generate and sense electric fields combined with scanning-like swimming movements are intended to extract further parameters like the size, shape and material properties of objects. Inspired by this biological example, this work introduces an application for active electrolocation based on reduced sensor movement sequences as presented in Wolf-Homeyer et al (2016 Bioinspir. Biomim. 11 055002). Initially, the application is conducted with a simulated receptor-system consisting of an emitter-dipole and an orthogonally arranged pair of sensor-electrodes. Close inspection of a minimal set of scanning movements allows the exclusion of sectors of the general search area early in the proposed localization algorithm (search area partitioning). Furthermore, the proposed algorithm is based on an analytical representation of the electric field and of the so-called EEV (ensemble of electrosensory viewpoints) (Solberg et al 2008 Int. J. Robot. Res. 27 529-48) rather than using computationally expensive FEM simulations, rendering it suitable for embedded computer systems. Two-dimensional discrete EEV contour-ring points (CRPs) of desired accuracy are extracted. In the core of the localization algorithm, fragments of the EEV are selected from valid sectors of the search area, which generates sets of CRPs, one for each sensor-emitter position/orientation. These sets are investigated by means of a nearness metric to find points in different sets which correspond to each other in order to estimate the object position. Two resultant scanning strategies/localization algorithms are introduced.

Effects of interprofessional education for medical and nursing students: enablers, barriers and expectations for optimizing future interprofessional collaboration - a qualitative study.

BACKGROUND: To ensure high quality patient care an effective interprofessional collaboration between healthcare professionals is required. Interprofessional education (IPE) has a positive impact on team work in daily health care practice. Nevertheless, there are various challenges for sustainable implementation of IPE. To identify enablers and barriers of IPE for medical and nursing students as well as to specify impacts of IPE for both professions, the 'Cooperative academical regional evidence-based Nursing Study in Mecklenburg-Western Pomerania' (Care-N Study M-V) was conducted. The aim is to explore, how IPE has to be designed and implemented in medical and nursing training programs to optimize students' impact for IPC. METHODS: A qualitative study was conducted using the Delphi method and included 25 experts. Experts were selected by following inclusion criteria: (a) ability to answer every research question, one question particularly competent, (b) interdisciplinarity, (c) sustainability and (d) status. They were purposely sampled. Recruitment was based on existing collaborations and a web based search. RESULTS: The experts find more enablers than barriers for IPE between medical and nursing students. Four primary arguments for IPE were mentioned: (1) development and promotion of interprofessional thinking and acting, (2) acquirement of shared knowledge, (3) promotion of beneficial information and knowledge exchange, and (4) promotion of mutual understanding. Major barriers of IPE are the coordination and harmonization of the curricula of the two professions. With respect to the effects of IPE for IPC, experts mentioned possible improvements on (a) patient level and (b) professional level. Experts expect an improved patient-centered care based on better mutual understanding and coordinated cooperation in interprofessional health care teams. To sustainably implement IPE for medical and nursing students, IPE needs endorsement by both, medical and nursing faculties. CONCLUSION: In conclusion, IPE promotes interprofessional cooperation between the medical and the nursing profession. Skills in interprofessional communication and roles understanding will be primary preconditions to improve collaborative patient-centered care. The impact of IPE for patients and caregivers as well as for both professions now needs to be more specifically analysed in prospective intervention studies.

A model of interprofessional problem-based learning for medical and nursing students: Implementation, evaluation and implications for future implementation.

Objective: In Germany there is little evidence of interprofessional problem-based learning (PBL) to date. For this reason a corresponding course for medical and nursing students was implemented. The goal was to analyse the feasibility and usefulness from the point of view of the students. Method: For the purposes of evaluation a quantitative observational study was conducted with a pre-course survey, a teaching evaluation and a post-course survey. The pre- and post-course surveys took place before the commencement of and after the conclusion of learning. The teaching evaluation was carried out after the conclusion of the interprofessional course. In total there were five medical students and five nursing students who took part. The descriptive data analysis was carried out using the statistics software package SPSS. The data from the open text fields was transcribed and evaluated using qualitative content analysis. Results: The students' assessment of the interprofessional PBL was predominantly positive. They stated that they were able to expand their knowledge of the roles of the other profession, that the interprofessional course had a positive effect in terms of mutual appreciation and that the tutor had a positive influence on the interprofessional PBL due to his cooperative learning support. Suggestions for improvement were concerned with the expansion of the interprofessional exchange and the establishment of a set timetable for the tutorials. Conclusion: The first study results of the Bildungscluster study can be used to make adjustments to the interprofessional PBL in order to be able to implement the course with a greater number of participants. Further studies are needed in order to comprehensively examine the learning effects and the impact on daily practice.

[Academic training of nursing professionals in Germany: further development of nursing expertise - results of the Care-N Study M-V]. / Akademische Pflegeausbildung in Deutschland: Ergebnisse zur pflegefachlichen Weiterentwicklung aus der Care-N Study M-V.

BACKGROUND: The development of innovative health care concepts is needed in order to meet the population's need for nursing care in the future. Nurses take over new and expanded roles with a higher degree of professional autonomy. This requires the further development of academic training options for nursing professionals. OBJECTIVES: To explore the developments regarding academic trainings for nurses: (a) what are the pros and cons?; (b) what are the features distinguishing nurses with an academic training from nurses with a three-year vocational training?; and (c) what are the wishes regarding the further development? The aim is to identify key components of further developments of the academic training of nursing professionals. METHODS: The Care-N Study M-V includes a qualitative Delphi survey to generate ideas and comprises two standardized, mailed questionnaires and a group discussion including 25 experts. RESULTS: The experts find more arguments in favour of a further development of academic trainings for nurses. The primary distinguishing criteria for an academically trained nurse compared to a nurse qualified in a three-year vocational training is a higher degree of professional autonomy in undertaking tasks. For the future development of academic training, the experts would like to see a significant contribution to ensure the provision of high quality nursing and an improvement of working conditions for nurses. CONCLUSIONS: The further development of academic trainings for nurses seems to be reasonable. To meet future challenges, it is necessary to adapt existing academic trainings as well as to develop and implement innovative training concepts in the field of academic nursing.

Electrolocation of objects in fluids by means of active sensor movements based on discrete EEVs.

Weakly electric fish use self-generated electric fields for communication and for active electrolocation. The sensor part of the biological system consists of a vast amount of electroreceptors which are distributed across the skin of the electric fish. Fish utilise changes of their position and body geometry to aid in the extraction of sensory information. Inspired by the biological model, this study looks for a fixed, minimal scanning strategy compiled of active receptor-system movements that allows unique identification of the positions of objects in the vicinity. The localisation method is based on the superposition of numerical extracted contour-rings of rotated and/or linearly shifted EEVs (Solberg et al 2008 Int. J. Rob. Res. 27 529-48), simulated by means of FEM. For the evaluation of a movement sequence, matrices of unique intersection points and respective contrast functions are introduced. The resultant optimal scanning strategy consists of a combination of a linear shift and a rotation of the original EEV.

[Expectations, requirements and limitations of future task sharing between the nursing profession and the medical profession: results from the Care-N Study M-V]. / Erwartungen, Wünsche und Grenzen der künftigen Aufgabenteilung von Pflege und Medizin - Ergebnisse der Care-N Study M-V.

BACKGROUND: The aging population causes a sustained increase in demand of medical and nursing care services. At the same time health care professionals are aging, too. This leads to a growing number of health care gaps. Therefore, the health care system needs to be reformed. This includes a reallocation of task between some of the health care professions. AIMS: This article addresses developments, potentials and limitations in the context of the future allocation of tasks between the nursing and the medical profession. Aim is to specify the future task sharing between nurses and physicians regarding expectations, requirements and limitations. METHODS: We conducted questionnaire based Delphi interviews with an interdisciplinary group of experts. (type aggregation of ideas). RESULTS: In the future, to expert's point of view, nurses will take over routine tasks in the medical and nursing health care supply. Task sharing by substitution is regarded with skepticism by experts. It requires a long time perspective and an early involvement of all stakeholders. CONCLUSIONS: Germany is at the beginning of the process of the future task sharing between nurses and physicians. The realization requires a comprehensive political support and further development of concepts including scientific implementation and evaluation.
