description: Background

In Competency-Based Medical Education (CBME), where competency-oriented and learner-centered teaching is essential, evaluating clinical instructors' feedback in Entrustable Professional Activities (EPAs) is crucial. This study employs Bloom's Taxonomy, developed by Benjamin Bloom in 1956, to assess the depth and instructional quality of clinical instructors' narrative feedback, aiming to enhance CBME teaching practices.

Summary of Work

This research analyzed 150 randomly selected feedback entries from a dataset of 9,304 on the Emyway platform, used by the Taiwan Society of Otorhinolaryngology–Head and Neck Surgery, from August 2022 to July 2023. Two medical education experts evaluated the feedback across Bloom’s Taxonomy's six cognitive levels: Remembering, Understanding, Applying, Analyzing, Evaluating, and Creating. Discrepancies were reconciled for consensus, followed by a statistical analysis of the cognitive distribution of feedback.

Summary of Results

Analysis showed a focus on lower cognitive skills in the feedback: 33% on Remembering, 61% on Understanding, and 66% on Applying. Higher cognitive levels—Analyzing (21%), Evaluating (31%), and Creating (1%)—were less frequently addressed, with only 18% of feedback reaching higher-order objectives compared to 53% for lower-order skills.

Discussion and Conclusion

The findings reveal a skew towards lower-order educational objectives in clinical instructor feedback within CBME. While aligning with clinical teaching needs, this indicates a gap in fostering advanced cognitive skills like complex analysis, evaluation, and creative problem-solving. The results suggest a shift towards more innovative teaching methods that promote creative thinking and independent problem-solving in trainees.

Take Home Message

1. Clinical feedback in CBME predominantly focuses on basic cognitive skills, highlighting the need for strategies that encompass a broader range of cognitive abilities.

2. CBME should evolve its training methodologies to foster advanced cognitive development and a culture of innovative problem-solving among medical learners.

description: Objective: To determine the prevalence of PAS and evaluate possible risk factors, focusing on sex differences, burnout, emotional distress, academic-social support, and coping strategies.

Method: A cross-sectional, retrospective, and comparative study was conducted through an online survey with medical students (MS) willing to participate anonymously.

Results: All students reported PAS and the majority to a moderate-severe degree. Comparing the presence of abuse within the academic environment between men and women, we found differences in the frequency of reporting emotional abuse and sexual. Also, we found differences in perceived academic social support from teachers and family members. Multiple logistic regression analysis showed sex and current sexual abuse inside school had the strongest association with PAS in MS, followed by a family history of depression and perceived less academic social support from family.

Discussion and conclusion: Timely identification of individuals at-risk will be critical to establish preventive strategies to limit the impact of PAS in MS, stress management programs, training coping skills, and offer prompt therapeutic alternatives when needed.

Chemical and Photometric Evolution of the Local Group Galaxy NGC 6822 in a Cosmological Context

description: Based on the photometric properties of NGC 6822 we derive a robust star formation history. Adopting this history we compute 15 models of galactic chemical evolution. All of them match present-day photometric properties. The dark halo mass in all models evolves according to the mass assembly history predicted by a $Λ$CDM cosmology. We model the evolution of the baryonic mass aggregation history in this cosmological context assuming that part of the gas available for accretion never falls into the system due to two different physical processes. For seven models we assume that during accretion the universal baryon fraction is reduced by reionization only. The best model of this first group, a complex model with an early outflow, fits the observed gaseous mass, and the O/H, C/O, and Fe/O present-day values. This model requires a lower upper mass limit for the IMF than that of the solar vicinity, in agreement with recent results by other authors. We have also computed eight models where, in addition to reionization, the accreted baryon fraction is reduced by large-scale shock heating.The best model of this series, that also requires and early outflow and a lower upper mass limit for the IMF,can marginally fit the gaseous mass and the O/H and C/O observed values.

description: The PMNS neutrino mixing matrix U_{PMNS} is in general a product of two unitary matrices U_{lep} and U_ν arising from the diagonalization of the charged lepton and neutrino mass matrices, U_{PMNS} = U^{\dagger}_{lep} U_ν. Assuming that U_ν is a bimaximal mixing matrix, we investigate the possible forms of U_{lep}. We identify three possible generic structures of U_{lep}, which are compatible with the existing data on neutrino mixing. One corresponds to a hierarchical ``CKM-like'' matrix. In this case relatively large values of the solar neutrino mixing angle θ_{sol}, and of |U_{e3}|^2, are typically predicted, \tan^2θ_{sol} \gtap 0.42, |U_{e3}|^2 \gtap 0.02, while the atmospheric neutrino mixing angle θ_{atm} can deviate noticeably from π/4, \sin^2 2θ_{atm} \gtap 0.95. The second corresponds to one of the mixing angles in U_{lep} being equal to π/2, and predicts practically maximal atmospheric neutrino mixing \sin^2 2θ_{atm} \simeq 1. Large atmospheric neutrino mixing, \sin^2 2θ_{atm} \gtap 0.95, is naturally predicted by the third possible generic structure of U_{lep}, which corresponds to all three mixing angles in U_{lep} being large. We focus especially on the case of CP-nonconservation, analyzing it in detail. We show how the CP-violating phases, arising from the diagonalization of the neutrino and charged lepton mass matrices, contribute to the measured neutrino mixing observables.

Know thyself: Nourishing authentic professional development in students: What can I do.
Creators: name: Reefman, Esther
name: Ploegmakers, Kim
Publisher: name: F1000 Research Limited
Year: 2024

description: Authentic & powerfull development of medical professionals requires awareness of their “sense of self”. At the heart of this awareness lie the answers to questions like, what are my beliefs and convictions, what drives me, what are my natural strengths and corresponding pitfalls, how aware am I of my thoughts and senses, how does this all influence the way I see the world and interact with people around me. This line of insight will enable the professionals to make more conscious decisions in line with their preferred identity and improve the quality of there connection and collaboration with colleagues and patients.  

Most medical curricula include professional development learning trajectories which to some extent may already address, directly or indirectly, the questions posed above. However, faculty, medical educators, teacher, mentors may struggle to elicit authentic development as amongst others students may not truly engage and be focused on “social acceptance by peers AND teachers. 

 

Additionally, authentic development opportunities are not restricted to these trajectories, but often happen in other parts of the curriculum and in between lessons. This workshop will address the general question: “How can we utilize these opportunies more effectively and what does that require of our own development? “
title: Socioeconomic Effects On Breast Cancer Survival : The Role Of Stage And Morphology
Creators: name: Kaffashian, Farrokh
Publisher: name: The Open University
Year: 2005

description: Background: Breast cancer patients of lower socioeconomic status tend to have poorer survival. This does not seem to be attributed solely to stage at presentation, but there is uncertainty as to the proportion of the survival deficit that is due to stage, and whether this is affected by the method of determining socioeconomic status. In this study, we estimate the extent to which the differences in survival by socioeconomic status, measured both by occupational and area-based methods, can be explained by differences between socioeconomic groups in stage and morphological type of tumour.

 Method and materials: We studied survival in 10,865 cases from the East Anglian Cancer Registry diagnosed between 1982 and 1993.

Results: In univariate analyses, lower social class was associated with relative hazards of 1.25 (95% Cl, 1.14-1.38) for death from all causes and 1.32 (95% Cl, 1.12-1.55) for death from breast cancer as underlying cause. Women resident in the most deprived area had relative hazards of 1.29 (95% Cl, 1.16-1.45) for death from all causes and 1.21 (95% Cl, 0.95-1.54) for death from breast cancer as underlying cause. Stage at diagnosis accounted for 28% of the effect of social class on survival to death from breast cancer. For survival to death from any cause, stage accounted for 63% of the effect of social class and 31% of the effect of deprivation category.

Discussion: The major finding is that we could not wholly or even largely account for socioeconomic effects on breast cancer survival by pathological factors including stage and morphology. It is concluded that stage at presentation explains some of the socioeconomic differences in breast cancer survival. Future research on histological grade and socioeconomic status is indicated. It would be useful to confirm these findings in additional studies that include other individual socioeconomic indices in addition to area-based and occupational measures.

description: Index-futures arbitragers only enter into the market if the deviation from the arbitrage relation is large enough to compensate for transaction costs and associated interest rate and dividend risks. We estimate the band around the theoretical futures price within which arbitrage is not profitable for most arbitragers, using a threshold autoregression model. Combining these thresholds with an error correction model, we can make a distinction between the effects of arbitragers and infrequent trading on index and futures returns.

description: Cortical regions without direct neuronal connections have been observed to exhibit synchronized dynamics. A recent empirical study has further revealed that such regions that share more common neighbors are more likely to behave coherently. To analytically investigate the underlying mechanisms, we consider that a set of n oscillators, which have no direct connections, are linked through m intermediate oscillators (called mediators), forming a complete bipartite network structure. Modeling the oscillators by the Kuramoto-Sakaguchi model, we rigorously prove that mediated remote synchronization, i.e., synchronization between those n oscillators that are not directly connected, becomes more robust as the number of mediators increases. Simulations are also carried out to show that our theoretical findings can be applied to other general and complex networks.

description: The tunnel current and magnetoresistance (TMR) are investigated in magnetic tunnel junctions consisting of a spin-filter tunnel barrier, sandwiched between a ferromagnetic (FM) electrode and a nonmagnetic (NM) electrode. The investigations are based on the transfer matrix method and the free-electron approximation. The numerical results show that the spin transport depends on the relative magnetization orientation of the FM electrode and the spin-filter barrier, such that the tunnel current reaches its maximum when the magnetic moments of the FM electrode and the magnetic barrier are parallel. It is also found that the TMR increases with increasing the applied voltage.

description: This paper presents an information criteria based model selection procedure (called FIC) for choosing the variables to be used in a linear regression. The penalty function is based on sums of critical values from particular F-distributions which are related to the small sample probabilities of incorrectly including additional regressors. Results from a Monte Carlo simulation study demonstrate that the performance of this new procedure is competitive with other asymptotically motivated procedures, while providing the practitioner with controls over the desired small sample probabilities of correct selection. An alternative, somewhat simpler selection criterion based on an asymptotic distribution is presented and compared to the finite sample criterion. Conditions for strong consistency of this variable selection procedure based on an approximate penalty function are presented.

Bayesian Analysis of a Cointegration Model Using Markov Chain Monte Carlo

Year: 1995

description: This paper presents a strategy for conducting Bayesian inference within the context of the triangular cointegration model. The numerical analysis is based on a hybrid of the Gibbs and Metropolis Markov Chain Monte Carlo methods. The use of a combination of two Markov Chain algorithms rather than a straight Gibbs Sampler occurs as a consequence of the complications induced by the prior specification. The specific form of the latter is, in turn, required for two purposes. First, in order to offset an identification problem which occurs when the cointegration model is extended to allow for the possibility of no cointegration. Second, in order to allow for an objective prior density on the parameter which determines the existence of cointegration.
Fractional Cointegration: A Bayesian Aproach

description: The concept of fractional cointegration, whereby deviations from an equilibrium relationship are allowed to follow a fractionally integrated process, has attracted some attention in the literature of late. The long memory aspect of the fractional process is seen as an appropriate characterization of slow reversion to an equilibrium relationship. This paper presents a Bayesian method for conducting inference within the context of a fractional cointegration model. The analysis is based on an approximate likelihood function, which is motivated by the need both to solve a fundamental identification problem and to produce a posterior density with a relatively simple algebraic form. Inferences are based on the associated marginal posterior densities, estimated by a hybrid of the Gibbs and Metropolis Markov Chain Monte Carlo methods.

description: We show a possibility that there exists a color ferromagnetic state in quark matter, in which a color magnetic field is spontaneously generated. The state arises between the hadronic state and the color superconducting state when the density of quarks is varied.Although the state (Savvidy state) has been known to involve unstablemodes of gluons, we show that the modes compose a quantum Hall state to stabilize the ferromagnetic state. Such a quantum Hall statecan arise only when quarks matter is present. We also show that the order of the phase transition between the state andthe quark gluon plasma is of the first order.

 Diagnosis. Characters of the Aturidae and the subfamily Notoaturinae. Dorsum with one large plate and three pairs of smaller plates. Configuration of the dorsal plates follows the general pattern of the Notoaturinae. One pair of anteromedial plates with the postocularia, anterolateral plates each with two pairs of glandularia, posterolateral plates with one pair of glandularia and the large posteromedial plate with three pairs of glandularia. First coxae long and pointed extending well beyond anterior body margin. Suture lines of coxae incomplete. Posterior margin of fourth coxal plates indistinct; near posterior margin a pair of glandularia. Another pair of glandularia on second coxal plates. On fourth coxal plates a pair of pointed humps. Five pairs of acetabula lying in the integument. Palp very long, especially PIV. PII elongated, ventral margin of segment with spine-like projections. First legs of male modified, I-leg-6 forming a sheath with a long claw with a long and slender clawlet. Claw with two short, hyaline claw blades. I-leg-5 slightly enlarged. Fourth legs of male relatively unmodified.
 Type species. Davidsia aurita n.sp.
 Etymology. Named after the Dutch acarologist Kees Davids (1931–2004). The gender is feminine.
 Remarks. The modified first legs are unique among the Notoaturinae; in the other six genera any leg modification has occurred on legs IV. Together with its unusual palp and the long projecting and pointed first coxal plates, the new genus differs well enough to warrant a separate status. The new genus has some superficial resemblance to the New Zealand genus Uralbia Hopkins, especially the palps of the two genera are similar. However, Uralbia differs in many other characters, noticeably the male genital field and the dorsal plates, with the anteromedial plate undivided and the loss of glandularia on other dorsal plates. Therefore, it is unlikely that the two genera are closely related, and there similarity is more the result of there hyporheic way of living.

A comparison of the supF test of Andrews (1993) shows that both tests are actually based on the same components.

description: The Nambu Jona-Lasinio Lagrangian offers an explication of the seemingly contradictory observations that a) the energy loss in the entrance channel of heavy ion reactions is not sufficient to thermalize the system and that b) the observed hadron cross sections are in almost perfect agreement with hydrodynamical calculations. According to this scenario, a critical opacity develops close to the chiral phase transition which equilibrates and hadronizes the expanding system very effectively. It creates as well radial flow and, if the system is not isotropic, finite $v_2$ values.

description: The choice of a compartmental spiking model is justified as a neuron model for this work. A brief description of such a model is given. The method of structural adaptation of the model to the input spike pattern is described. The general scheme of the compartmental spiking neurons organization into a network for solving the classification problem is given. The time-to-first-spike method is chosen as encoding numerical information into spike patterns. Brief results of experiments on solving the classification problem on publicly available data sets (Iris, MNIST) are presented. The conclusion is made about the comparability of the obtained results with the existing classical methods.

description: This paper examines the spill-overs in both returns and volatility between the London and New York stock markets during overlapping trading hours. Using high-frequency data for the FTSE 100 and S&P 500 stock index futures, we estimate the seasonal patterns in volatility using the Flexible Fourier Form specification of Gallant (1981). For both markets, volatility is estimated to be higher in the morning and late afternoon, as compared to the rest of the day. The estimated seasonals are used to adjust the returns before conducting the lead-lag analysis. The results indicate that both markets influence each other, although the impact of the US on the UK is clearly stronger.

Year: 2014

description: Outlined in this report are the findings of the social, ecological, and economic factors that should be considered when implementing sustainable housing as requested upon by the University of British Columbia’s (UBC) Farm. A triple bottom line analysis of the social, ecological, and economic factors that should be considered when implementing sustainable housing is performed on three different sustainable developments. The important social factors when considering sustainable housing are creating social spaces, encouraging diversity, and educating people on sustainability. Key ecological criteria are reduction of green house gases, reduction of energy and water consumption, waste management, and use of recyclable and rapidly renewable building materials. Economic factors which should be considered are reduction of living costs, use of energy efficient appliances, in-residence energy monitoring devices, per-unit utility billing, and a biomass facility for providing heat and hot water.

description: For about two years, the climate youth activism initiative Fridays for Future has addressed climate emergency, receiving considerable attention because of their consistent protests every week in many different locations worldwide. Based on empirical studies in Austria and Portugal, this paper investigates the motivations of students to participate in the movement and the solutions proposed by young activists to fight against climate emergency. Moreover, we discuss the integration of climate change activism into ESD (education for sustainable development) and transformative learning processes, and how this enables environmental citizenship. The results of the studies reveal that emotions and feelings of solidarity and collective aims are motives to participate in the strikes. The young activists sometimes propose innovative and sometimes radical solutions to climate emergency. Both demonstrations and exhibitions as forms of bottom-up climate activism initiatives contribute to engagement in political dialogue and scientific knowledge transfer. They can be seen as “triggers of change” for transformative learning.

title: The path of the senses: kinship, intimacy and sensory experience in Pehuen Mapu, Chile
Creators: name: Piña A., Gabriela
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2022

description: Based on fieldwork among indigenous Pehuenche people living in the Andes in southern Chile, this thesis comprises an ethnographic exploration of intimate relationships that begin in Pehuenche households and expand outwards through various shared spaces. It shows how the shared sensorial experiences of these places act as vehicles for sociality and how children are introduced into these social dynamics. The first part of the thesis is primarily concerned with interactions that take place inside the house and examines how Pehuenche people engage in relationships with their closest kin inside the family home and with other households. It begins with an analysis of mate drinking, which affects the drinkers’ perception of time and allows them to cultivate affectionate horizontal relations with each other. It then turns to the way in which the Pehuenche move beyond their households and expand their relationships through visiting and hosting as a key way of cultivating voluntary relationships. Next, the thesis provides an analysis of marriage and the potential conflict that arises between the traditionally hierarchical parent-child relation and the fostering of personal agency in partner selection. Together, these three chapters delineate a model of horizontal, voluntary, and caring relationships that I argue are strongly rooted in shared sensorial experiences, which are key for navigating hierarchy, the threat of witchcraft attacks as well as cultural change. The second part of the thesis expands outwards to consider sociality in settings further afield, notably the forest, the state school, and the Nguillatun fertility ritual. Pehuenche people routinely engage in relationships with non-human entities during their seasonal migration to the uncultivated forest, where children acquire traditional Pehuenche knowledge, skills, and ways of relating to the landscape. The state school, meanwhile, is effectively a hybrid space in which the model of relationships cultivated inside the household is confronted with practices of assimilation pushing people to blend into mainstream Chilean culture. This causes conflict between the community and school staff. Finally, through participation in the Ngillatun fertility ritual, and especially the sensorial experiences it entails, the Pehuenche are able to go beyond one-to-one bonds to establish a relation with their whole ritual community. The thesis contributes to anthropological understandings of Amerindian kinship and sociality by underscoring the role of shared sensorial experiences in creating relatedness that is grounded in the body but not necessarily on consubstantiality. It shows how sensory experiences comprise a thread connecting together Pehuenche understandings of similarity and difference, cooperation and amity.

description: Janszoonia n.gen.
 Diagnosis. Characters of the family Athienemanniidae and the subfamily Notomundamellinae. Dorsal and ventral shields present, dorsal furrow complete. Dorsal shield large, with three pairs of glandularia and a pair of postocularia. Dorsal shield without apophyses. Eyes absent. Eight pairs of acetabula on small platelets within the gonopore, four pairs on the posterior platelets, one pair on the middle platelets and three pairs on the anterior platelets. Laterally of gonopore, four small acetabula irregularly placed on a ridge-like structure. Palp rotated.
 Type species: Janszoonia difficilis n.sp.
 Etymology. Named after the Dutch sailor Willem Janszoon, possibly the first European to reach Australia in 1606. The gender is feminine.
 Remarks. From Australia three genera are known: Notomundamella Cook, Mellamunda Harvey and Davecookia Harvey, all belonging to the endemic subfamily Notomundamellinae. The latter genus is described from the same locality as the new genus described here. None of the known members of the Notomundamellinae has a similar configuration of the acetabula. Notomundamella has a dorsal shield with apophyses (absent in the new genus), while the gonopore has three lobes with numerous acetabula. Mellamunda has eight acetabula within the gonopore, but not on platelets, and 5–7 pairs in the ventral shield. Davecookia has five pairs of acetabula within the gonopore (three large pairs and two small ones), no acetabula in the ventral shield and the female has a very broad gonopore. The new genus is most closely related to Mellamunda, as both females have acetabula within the gonopore and acetabula incorporated into the ventral shield. However, the genital field of Mellamunda differ completely from those of the new genus. The acetabula of Mellamunda are partly covered by the idiosoma and not on platelets. The acetabula of the new genus within the integument are lying on platelets, while those outside the integument are located on a ridge-like structure. These differences warrant a separate status of the new genus.

description: Observations by the Parker Solar Probe mission of the solar wind at about 35.7 solar radii reveal the existence of whistler wave packets with frequencies below 0.1 f/fce (20-80 Hz in the spacecraft frame). These waves often coincide with local minima of the magnetic field magnitude or with sudden deflections of the magnetic field that are called switchbacks. Their sunward propagation leads to a significant Doppler frequency downshift from 200-300 Hz to 20-80 Hz (from 0.2 f/fce to 0.5 f/fce). The polarization of these waves varies from quasi-parallel to significantly oblique with wave normal angles that are close to the resonance cone. Their peak amplitude can be as large as 2 to 4 nT. Such values represent approximately 10% of the background magnetic field, which is considerably more than what is observed at 1 a.u. Recent numerical studies show that such waves may potentially play a key role in breaking the heat flux and scattering the Strahl population of suprathermal electrons into a halo population.

description: The energies of low-lying bound states of a microscopic quantum many-body system of particles can be worked out in a reduced Hilbert space. We present here and test a specific non-perturbative truncation procedure. We also show that real exceptional points which may be present in the spectrum can be identified as fixed points of coupling constants in the truncation procedure.
