Beyond the Sex Binary: Toward the Inclusive Anatomical Sciences Education

Developments in biology and genetics in recent decades have caused significant shifts in the understanding and conceptualization of human biological variation. Humans vary biologically in different ways, including individually, due to age, ancestry, and sex. An understanding of the complexities of all levels of biological variation is necessary for efficient health care delivery. Important steps in teaching medical students about human variation could be carried out in anatomy classes, and thus, it is important that anatomical education absorbs new developments in how biological variation is comprehended. Since the early 1990s biological sex in humans has been vigorously investigated by scientists, social scientists, and interest groups. Consequently, the binary division in male and female sex has been called into question and a more fluid understanding of sex has been proposed. Some of the major textbooks teach anatomy, particularly of the urogenital system, as a male-female binary. Anatomical sciences curricula need to adopt a more current approach to sex including the introduction of the category of “intersex”/“differences in sexual development” and present sex as a continuum rather than two sharply divided sets of characteristics. This approach offers a better understanding of the complexity of sex differences and, at the same time, provides students with an improved theoretical framework for understanding human variation in general, transcending the limitations of biological typology. When well delivered, the non-binary approach could play a significant contribution to the formation of competent and responsible medical practitioners and avoidance of problematic practices such as non-consensual “normalizing” surgeries.     

Problem-based learning in formal and informal learning environments

Problem-based learning (PBL) is a student-centered instructional strategy in which students solve problems and reflect on their experiences. Different domains need different approaches in the design of PBL systems. Therefore, we present one case study in this article: A Java Programming PBL. The application is developed as an additional module for the Learning Management System (LMS). This way the LMS is extended by PBL functionality and the LMS learning resources can be used in PBL.     

Does a perceptuomotor skills assessment have added value to detect talent for table tennis in primary school children?

ABSTRACT

Talent detection intends to support lifelong sports participation, reduce dropouts and stimulate sports at the elite level. For this purpose it is important to reveal the specific profile which directs children to the sports that connect to their strengths and preferences. This study evaluated a perceptuomotor skills assessment as part of talent detection for table tennis, a sport in which perceptuomotor skills are considered essential to cope with the difficult technical aspects. Primary school children (n = 121) and gifted young table tennis players (n = 146) were assessed using the Dutch perceptuomotor skills assessment measuring “ball control” and “gross motor function”. A discriminant function analysis confirmed the added value by identifying primary school children fitting the table tennis perceptuomotor profile of the young gifted table tennis players (28%). General linear model analyses for the assessment’s individual test items showed that the table tennis players outperformed their primary school peers on all “ball control” items (P < 0.001). In conclusion, the assessment appears to be of added value for talent detection in table tennis at this young age. Longitudinal studies need to reveal the predictive value for sports participation and elite sports.     

Forced Disruption of Anatomy Education in Australia and New Zealand: An Acute Response to the Covid-19 Pandemic

Australian and New Zealand universities commenced a new academic year in February/March 2020 largely with “business as usual.” The subsequent Covid-19 pandemic imposed unexpected disruptions to anatomical educational practice. Rapid change occurred due to government-imposed physical distancing regulations from March 2020 that increasingly restricted anatomy laboratory teaching practices. Anatomy educators in both these countries were mobilized to adjust their teaching approaches. This study on anatomy education disruption at pandemic onset within Australia and New Zealand adopts a social constructivist lens. The research question was “What are the perceived disruptions and changes made to anatomy education in Australia and New Zealand during the initial period of the Covid-19 pandemic, as reflected on by anatomy educators?.” Thematic analysis to elucidate “the what and why” of anatomy education was applied to these reflections. About 18 anatomy academics from ten institutions participated in this exercise. The analysis revealed loss of integrated “hands-on” experiences, and impacts on workload, traditional roles, students, pedagogy, and anatomists' personal educational philosophies. The key opportunities recognized for anatomy education included: enabling synchronous teaching across remote sites, expanding offerings into the remote learning space, and embracing new pedagogies. In managing anatomy education's transition in response to the pandemic, six critical elements were identified: community care, clear communications, clarified expectations, constructive alignment, community of practice, ability to compromise, and adapt and continuity planning. There is no doubt that anatomy education has stepped into a yet unknown future in the island countries of Australia and New Zealand.     

Nonlinear modeling and robust LMI fuzzy control of overhead crane systems

Overhead cranes are widely used structures for lifting and conveying heavy loads. The development of feedback control systems for such equipment is important due to the large number of potential applications and advantages over manual operation concerning stability and robustness. This paper aims to represent the key nonlinear dynamics of crane systems by means of a state-space fuzzy model with compact rule-base structure. The fuzzy model is useful to assist the design of a fuzzy controller based on the concept of parallel compensation. A well-posed conservative linear-matrix-inequality (LMI) feasibility problem is formulated so that a solution guarantees closed-loop Lyapunov stability, bounded control inputs, quick positioning of the supporting cart, and suppression of load oscillations and collisions. The fuzzy controller is composed by rules with linear control laws derived from local state-space models. The controller warrants asymptotic convergence of the states. Due to the nonlinear nature of the fuzzy model and controller, Jacobian linearization is avoided. The proposed fuzzy control approach for cranes has shown to be more effective and robust than an optimal quadratic controller, and able to move cargo smoothly and safely to a destination. Particularly, constrained and smoother control inputs avoid actuator saturation, and tend to increase its lifetime. Laboratory experiments using the LMI fuzzy controller and actual data validates the approach for cranes in actual scenario.     

Musculoskeletal anatomy knowledge in Australian chiropractors

Anatomy is a key knowledge area in chiropractic and is formally offered in the undergraduate component of chiropractic education. There is the potential for loss of anatomy knowledge before the opportunity to apply it in a clinical setting. This study aimed to determine whether chiropractic clinicians retain a level of anatomy knowledge comparable to that of chiropractic students and to compare chiropractors' self-rating of their anatomical knowledge against an objective knowledge assessment tool. A previously validated multiple-choice test was utilized to measure retention of limb musculoskeletal (MSK) knowledge in Australian chiropractors. One hundred and one registered chiropractors completed the questionnaire and responses were scored, analyzed, and compared to scores attained by undergraduate and postgraduate chiropractic students who had previously completed the same questionnaire. The results indicated that practitioners retained their anatomy knowledge, with a significantly higher total mean score than the undergraduate group [total mean score = 36.5% (±SD 13.6%); P < 0.01] but not significantly different to the postgraduate group [total mean score = 52.2% (±SD 14.1%); P = 0.74]. There was a weak positive correlation between chiropractors' self-rated knowledge and test performance scores indicating the effectiveness of this Australian chiropractic group in self-assessing their anatomy knowledge. This study found that Australian chiropractors' knowledge of MSK anatomy was retained during the transition from university to clinical practice and they accurately evaluated their own test performance.     

An organic view of students’ want formation: pragmatic rationality,habitus and reflexivity

Based on interviews with and questionnaires completed by upper secondary school pupils (n = 27) from academic and vocational programmes, respectively, the present paper focuses on some of the social and individual conditions that precede the individual decision-making process in education transitions. The paper shows that an organic view of decision-making is in better accordance with observations than is a hierarchical view, and thus supports previous research claiming that pragmatic rationality (based on habitus and reflexivity) plays a more important role in students’ decision-making processes than does instrumental rationally.     

Attitudes of Anatomy Students toward Commemorations for Body Donors: A Multicultural Perspective

Many medical schools practice commemorative ceremonies to honor body donors. Attitudes of medical education stakeholders toward these ceremonies have not yet been fully investigated. The aim of this study was to explore anatomy students' attitudes toward commemorations at a multicultural institution which has not introduced these ceremonies yet. A survey was carried out on different groups of anatomy students that were exposed and not yet exposed to human remains. The survey was used to record basic demographic data from the respondents, ask if they would support the establishment of an anatomy commemoration and in which format. A total of 756 anatomy students participated in the survey (response rate 69.8%). The majority (76.3%) were in favor of introducing a commemoration for donors. The associations of students' gender, attitude toward body donation, and level of exposure to human remains with attitudes toward commemoration for donors were identified (P < 0.05), whereas ethnicity and religion seemed to have no influence on attitudes (P > 0.05). Most students believed that anatomy staff and students should organize the commemoration. There was a preference for the commemoration to be secular with revealed identities of donors, and not recorded for social media. The support for the establishment of commemorations transcended cultural and religious differences and confirmed students' respectful attitude toward donors. Anatomy commemorations seem to have potential not only to engage students with one another, and donor families, but also to pave the way for students to become life-long ethical and empathetic learners and practitioners.
