The Burden of Burnout: An Assessment of Burnout Among Internal Medicine Residents After the 2011 Duty Hour Changes.

This study sought to determine burnout prevalence and factors associated with burnout in internal medicine residents after introduction of the 2011 ACGME duty hour rules. Burnout was evaluated using an anonymized, abbreviated version of the Maslach Burnout Inventory. Surveys were collected biweekly for 48 weeks during the 2013-2014 academic year. Burnout severity was compared across subgroups and time. A score of 3 or higher signified burnout. Overall, 944 of 3936 (24%) surveys were completed. The mean burnout score across all surveys was 2.8. Categorical residents had higher burnout severity than noncategorical residents (2.9 vs 2.7, P = .005). Postgraduate year 2 residents had the highest burnout severity by year (3.1, P < .001). Residents on inpatient rotations had higher burnout severity than residents on outpatient or consultation rotations (3.1 vs 2.2 vs 2.2, P < .001). Night float rotations had the highest severity (3.8). Burnout remains a significant problem even with recent duty hour modifications.

What toleration means to contemporary liberalism?

Toleration is a key concept of liberalism, both from the historical and conceptual points of view. On the other hand, as people’s freedom to live according to their moral and religious ideas has long become a basic value for liberal societies and their political constitutions, it is reasonable to understand that there is nothing to be tolerated nor by citizens neither by the State. However, a part of the scope and meaning of the fundamental rights and freedoms is subject to what John Rawls calls reasonable disagreements and this is a field where toleration understood in the classic way is compatible with equality: not to intervene against that which is being disapproved understood has a raison d'être. Since the 1980s, toleration has been present in the debates on how to deal with pluralism in a constitutional democracy. This has to be connected to the rise of identity politics: political and intellectual movements such as multiculturalism or comunitarism that questioned whether social order based on neutral criteria was either possible or desirable or both things at the same time. Outstanding liberal philosophers were among those demanding political priority for comunitarian values and those who showed interest for toleration as a key concept to articulate pluralism. Key distinctions between them can be explained as the result of the different approaches they take when facing classical theories on toleration: whereas John Locke’s is a major influence on Rawls, John Stuart Mill’s is on the others, while Gray, Walzer and Rorty follow Isaiah Berlin’s reading of Mill.

Problema di Cauchy-Dirichlet per l'equazione del calore

In quest'elaborato si risolve il problema di Cauchy-Dirichlet per l'equazione del calore, prendendo come oggetto d'esame una sbarra omogenea. Nel primo capitolo si studiano le serie di Fourier reali a partire dalle serie trigonometriche; vengono dati, poi, i principali risultati di convergenza puntuale, uniforme ed in L^2 e si discute l'integrabilità termine a termine di una serie di Fourier. Il secondo capitolo tratta la convergenza secondo Cesàro, le serie di Fejèr ed i principali risultati di convergenza di queste ultime. Nel terzo, ed ultimo, capitolo si risolve il Problema di Cauchy-Dirichlet, distinguendo i casi in cui il dato iniziale sia di classe C^1 o solo continuo; nel secondo caso si propone una risoluzione basata sulle serie di Fejér e sul concetto di barriera ed una utilizzando il nucleo di Green per l'equazione del calore.
