Thresholds of becoming: an exploration of threshold concepts as a means to support professional identity formation in competency-based curricula
Inherent in every clinical preceptor’s role is the ability to understand the learning needs of individual trainees, enabling them to meet their potential. Competency-based medical education frameworks have been developed to this end, but efforts to identify behaviours and activities that define competence are based on mapping knowledge, skills and ability, which can be difficult to integrate into a comprehensive picture of who the trainee is becoming. Professional identity formation, in contrast, prioritizes attention to who trainees are becoming, but provision of detailed guidance to preceptors on how to best support this form of development is challenging. The tension that results limits our ability to optimally support learners as strengths in competency development may mask professional identity development gaps and vice versa. To address this tension, this paper examines how the theory of threshold concepts – troublesome ideas that, once appreciated, fundamentally change how you understand and approach a particular activity – can shine light on professional identity formation and its relationship with developing competence. The recognition and identification of threshold concepts is offered as a means to improve our ability to identify, discuss and support behaviours and actions that impact the learner’s capacity to act competently as they develop their identity at various stages of training.

Landscape connectivity for bobcat (Lynx rufus) and lynx (Lynx canadensis) in the Northeastern United States
Landscape connectivity is integral to the persistence of metapopulations of wide ranging carnivores and other terrestrial species. The objectives of this research were to investigate the landscape characteristics essential to use of areas by lynx and bobcats in northern New England, map a habitat availability model for each species, and explore connectivity across areas of the region likely to experience future development pressure. A Mahalanobis distance analysis was conducted on location data collected between 2005 and 2010 from 16 bobcats in western Vermont and 31 lynx in northern Maine to determine which variables were most consistent across all locations for each species using three scales based on average 1) local (15 minute) movement, 2) linear distance between daily locations, and 3) female home range size. The bobcat model providing the widest separation between used locations and random study area locations suggests that they cue into landscape features such as edge, availability of cover, and development density at different scales. The lynx model with the widest separation between random and used locations contained five variables including natural habitat, cover, and elevation-all at different scales. Shrub scrub habitat-where lynx's preferred prey is most abundant-was represented at the daily distance moved scale. Cross validation indicated that outliers had little effect on models for either species. A habitat suitability value was calculated for each 30 m2 pixel across Vermont, New Hampshire, and Maine for each species and used to map connectivity between conserved lands within selected areas across the region. Projections of future landscape change illustrated potential impacts of anthropogenic development on areas lynx and bobcat may use, and indicated where connectivity for bobcats and lynx may be lost. These projections provided a guide for conservation of landscape permeability for lynx, bobcat, and species relying on similar habitats in the region.

Rheumatoid arthritis reprograms circadian output pathways
Objective
We applied systems biology approaches to investigate circadian rhythmicity in rheumatoid arthritis (RA).
Methods
We recruited adults (age 16–80 years old) with a clinical diagnosis of RA (active disease [DAS28 > 3.2]). Sleep profiles were determined before inpatient measurements of saliva, serum, and peripheral blood mononuclear leukocytes (PBML). Transcriptome and proteome analyses were carried out by RNA-SEQ and LC-MS/MS. Serum samples were analysed by targeted lipidomics, along with serum from mouse collagen induced-arthritis (CIA). Bioinformatic analysis identified RA-specific gene networks and rhythmic processes differing between healthy and RA.
Results
RA caused greater time-of-day variation in PBML gene expression, and ex vivo stimulation identified a time-of-day-specific RA transcriptome. We found increased phospho-STAT3 in RA patients, and some targets, including phospho-ATF2, acquired time-of-day variation in RA. Serum ceramides also gained circadian rhythmicity in RA, which was also seen in mouse experimental arthritis, resulting from gain in circadian rhythmicity of hepatic ceramide synthases.
Conclusion
RA drives a gain in circadian rhythmicity, both in immune cells, and systemically. The coupling of distant timing information to ceramide synthesis and joint inflammation points to a systemic re-wiring of the circadian repertoire. Circadian reprogramming in response to chronic inflammation has implications for inflammatory co-morbidities and time-of-day therapeutics.

College Connectedness: The Student Perspective
Connectedness and integration are essential elements of student satisfaction, academic success, and retention. Despite its importance in the lives of college students, research on connectedness has approached the concept from definitional perspectives other than those of students. This multi-study explores connectedness from the student perspective while drawing from social identity theory and student involvement theory. In Study 1, students described their experiences and perceptions of connectedness in focus groups. Study 2 built on the qualitative findings of Study 1 and empirically tested connectedness as defined by the students. Results of the study indicate the need for a student definition of connectedness and provide practical suggestions for those in higher education.Keywords: connectedness, social identity theory, student involvement theory, instrument design, higher education

An autoethnographic exploration of the use of goal oriented feedback to enhance brief clinical teaching encounters
Supervision in the outpatient context is increasingly in the form of single day interactions between students and preceptors. This creates difficulties for effective feedback, which often depends on a strong relationship of trust between preceptor and student. Building on feedback theories focusing on the relational and dialogic aspects of feedback, this study explored the use of goal-oriented feedback in brief encounters with learners. This study used autoethnography to explore one preceptor’s feedback interactions over an eight-month period both in the ambulatory setting and on the wards. Data included written narrative reflections on feedback interactions with twenty-three learners informed by discussions with colleagues and repeated reading of feedback literature. Thematic and narrative analyses of data were performed iteratively. Data analysis emphasized four recurrent themes. (1) Goal discussions were most effective when initiated early and integrated throughout the learning experience. (2) Both learner and preceptor goals were multiple and varied, and feedback needed to reflect this complexity. (3) Negotiation or co-construction of goals was important when considering the focus of feedback discussions in order to create safer, more effective interactions. (4) Goal oriented interactions offer potential benefits to the learner and preceptor. Goal oriented feedback promotes dialogue as it requires both preceptor and learner to acknowledge and negotiate learning goals throughout their interaction. In doing so, feedback becomes an explicit component of the preceptor–learner relationship. This enhances feedback interactions even in relatively brief encounters, and may begin an early educational alliance that can be elaborated with longer interactions.

Exploring latent clusters in pediatric OCD based on symptoms, severity, age, gender, and comorbidity
Given diverse symptom expression and high rates of comorbid conditions, the present study explored underlying commonalities among OCD-affected children and adolescents to better conceptualize disorder presentation and associated features. Data from 830 OCD-affected participants presenting to OCD specialty centers was aggregated. Dependent mixture modeling was used to examine latent clusters based on their age- and gender adjusted symptom severity (as measured by the Children’s Yale-Brown Obsessive-Compulsive Scale; CY-BOCS), symptom type (as measured by factor scores calculated from the CY-BOCS symptom checklist), and comorbid diagnoses (as assessed via diagnostic interviews). Fit statistics favored a four-cluster model with groups distinguished primarily by symptom expression and comorbidity type. Fit indices for 3–7 cluster models were only marginally different and characteristics of the clusters remained largely stable between solutions with small clusters of distinct presentations added in more complex models. Rather than identifying a single classification system, the findings support the utility of integrating dimensional, developmental, and transdiagnostic information in the conceptualization of OCD-affected children and adolescents. Identified clusters point to the centrality of contamination concerns to OCD, relationships between broader symptom expression and higher levels of comorbidity, and the potential for complex/neurodevelopmental presentations.

Molecular scatology as a conservation tool
The threat from large carnivores to livestock has been controversial worldwide. Technologies now exist to examine the dietary content of predators through scat analysis. This study of puma and jaguar diets on a cattle ranch in the Venezuelan llanos examined scat, kills, and ranch records. Mitochondrial DNA analysis of the scat determined which species the scat belonged to. The results indicate an overall low level of death from predation compared with other causes, and that predation could be attributed mostly to puma kills, and only slightly to jaguar kills.
