Communities of Practice: Redressal of Medical Education Leadership Challenges through a Workplace-Based Learning Approach
Authors: Ahmad Syeda Amina 
Published: September 2023

Background: There is a realization that learning leadership skills is beyond classroom teaching and requires leaders to participate in communities of practice (CoP) that enables them to learn from the wisdom of seasoned leader because such leaders don’t ask budding leaders to follow their instructions, they rather set examples of best practices in medical education. However, dearth of published evidence both locally and internationally suggests that there is a need to investigate how have communicates of practice impacted leadership skills of physicians as medical education leaders.
Participants and Methods: A transcendental phenomenological study was conducted, involving seven physician leaders working as medical teachers from both basic and clinical sciences, heading the medical college and/or their departments as professors in a medical college on the basis of convenience sampling and their experiences as medical education leaders who had presumably experienced the phenomenon of ‘learning leadership skills’. The researcher conducted hour-long one-on-one interviews with participants at their workplace offices and one interview was conducted at the researcher’s home office. One of the participants was interviewed twice as additional gaps were identified from the initial analysis. Interviews conducted in the surgeon’s office were interrupted many a times by theatre assistants, but the continuity was resumed successfully. The qualitative data was analyzed manually by using the Stevick-Colaizzi-Keen method.
Results: One major theme namely ‘communities of practice impacting leadership skills’ emerged from the transcripts whereas, two subthemes namely ‘gaining wisdom’ and ‘uplifting emotional wellbeing’ were identified as main aspects that had a major influence on leadership skills of physicians in the medical education milieu.
Conclusion: CoP has a positive impact on leadership skills. It enables leaders in medical education to learn wisdom to solve difficult leadership problems. Evidence supports that CoP also uplifts emotional wellbeing of leaders by preventing their burn out.

Background: Student’s academic performance is the major concern for the educational sector because students are the future practitioners who will serve the society. The academic performance of students is a key feature in teaching. The present study aims to determine the relationship between academic performance, purpose in life and hopelessness among final year MBBS students, by taking hopelessness as predicting variable.
Methodology: A Correlational study was conduct at Fatima Jinnah Medical University, Lahore Pakistan. A total no. of 240 final year medical students were included by using convenient sampling technique and they were administered Purpose in Life (PIL) Scale and Beck’s Hopelessness Scale (BHS) along with demographic details. The academic performance of students was measured through 4th year academic scores. Hopelessness was taken as independent variable (IV), while, academic performance and purpose in life served as dependent variables (DVs).
Results: The mean age of students was 22.5 years. Results found negative correlation between hopelessness and academic performance (p<0.01), as well as a negative correlation between hopelessness and purpose in life (p <0.01). Hopelessness negatively predicted academic performance (β= -.19, p<.01) and purpose in life (β= -.72, p<.001) among students. Total 25% students were in the normal range of hopelessness, 45.4% students scored in mild range, 23.8% students were in the moderate category, while 5.8% students were found in the severely hopeless category.
Conclusion: The study concluded that hopelessness does not only predict purpose in life negatively among students but also affect their academic performance. A wide range of students were found hopeless therefore, various interventions for the prediction of hopelessness in various academic institutes should be made by involving appropriate educational and administrative measures.

В данной статье представлен сравнительный анализ экономической целесообразности использования модернизированных судов наряду с новыми морскими автономными надводными судами (МАНС) в условиях нестабильной мировой экономики. Определены основные проблемы эскортирования судов в стеснённых условиях плавания, подхода, швартовки к причалу, при ограниченной пропускной способности портов и диспетчеризации в узкостях. Противоречия между прогнозируемой разницей стоимости и эффективностью применением концепции системы автономного судовождения в порту (БЭС-СП) на базе технологии двух опорных точек и МАНС способствуют постановке цели данного исследования. Рассмотренный с точки зрения двух парадигм вариант модернизации судов до четвертого уровня автономности посредством метода аналогии определил ряд проблем, в числе которых невозможность её полноценной реализации. Сделан вывод о том, что повышение уровня безопасности и автономности, а также исключение человеческого фактора, предполагают возможность использования азимутальных буксиров-автоматов в рамках концепции БЭС-СП, являющейся государственным заказом.
The article presents a comparative analysis of the economic feasibility of using modernized ships along with new maritime autonomous surface ships (MASS) in an unstable global economy. The main problems of escorting ships in narrows, approaches, when mooring to a berth and dispatching with limited port capacity and in congested waters are identified. The contradictions between the predicted cost difference and the effectiveness of applying the concept of the unmanned ship navigation system in the port based on the technology of two reference points and MASS helps to formulate the goal of this study. Considered from the point of view of the two paradigms, the option of upgrading ships to the fourth level of autonomy through the analogy method identified a number of problems, including the impossibility of its full implementation. It is concluded that increasing the level of safety and autonomy, as well as eliminating the human factor, involves using azimuthal automatic tugboats as a part of the concept of the unmanned ship navigation system in the port, which is a part of the state order.

Успех реализации Морского автономного надводного судна (МАНС) заключается прежде всего в надежности, бесперебойности и работоспособности различных навигационных систем, применяемых в автономных судах. Эти требования распространяются прежде всего на интеллектуальные системы мониторинга, прогнозирования, планирования и принятия решений, которые образуют интеллектуальную Систему поддержки принятия решений (СППР) безопасности судовождения в режиме реального времени [1]. Одна из наиболее сложных задач решаемых СППР – это задача предупреждения столкновений судов (ЗПР/ПСС) . Сложность ( ЗПР/ПСС) заключается в проблеме многофакторного анализа, связей и противоречий интересов частей и системы в целом. На этапе разработки концепции автономного судна должна быть выполнена предварительная оценка навигационных систем по критериям надежности и точности для их установки на морских автономных и дистанционно управляемых надводных судах. Эта оценка должна включать список и всесторонний анализ навигационных систем, которые должны использоваться для решения ( ЗПР/ПСС). Кроме того, должны быть разработаны технологические методы повышения точности источников навигационной информации, схемы резервирования, комплексирования в случае отказа или угрозы изменения нормальных рабочих режимов навигационного оборудования МАНС для решения со стороны злоумышленников.
The success of the implementation of the Maritime Autonomous Surface Vessel (MANS) lies primarily in the reliability, un-interrupted operation and performance of various navigation systems used in autonomous ships. These requirements apply first of all to intelligent systems for monitoring, prediction, planning and decision-making, which form an intelligent decision support system (DSS) for the safety of navigation in real time mode [1]. One of the most difficult tasks solved by the DSS is the collision avoidance. The complexity of collision avoidance challenge lies in the problem of multivariate analysis, connections and contradictions between the interest’s parts of the system and such system itself. At the stage of developing the concept of an autonomous vessel, a preliminary assessment of navigation systems should be carried out according to the criteria of reliability and operability before their installation on marine autonomous and remotely controlled surface vessels. This assessment should include a list and a comprehensive analysis of the navigation systems to be used to solve the task of ship collision avoidance. Additionally technological methods should be developed to improve the accuracy of navigation information sources, redundancy schemes, and integration in a case of failure or a threat to change the normal operating modes of MANS navigation equipment to solve the task of ship collision avoidance by intruders.
