The aim of this study was to analyse the composition, structure and spatial and temporal patterns of diversity and abundance of the ichthyofauna of the Santa Cruz Reservoir in semi-arid Brazil. Data were collected quarterly at eight sampling locations on the reservoir between February 2010 and November 2011 using gillnets from 12- to 70-mm mesh that were left in the water for 12h00min during th...

Denaturing gradient gel electrophoresis (DGGE) of amplified fragments of genes coding for 16S rRNA was used to study the development of bacterial communities during decomposition of crop residues in agricultural soils. Ten strains were tested, and eight of these strains produced a single band. Furthermore, a mixture of strains yielded distinguishable bands. Thus, DGGE DNA band patterns were use...

BACKGROUND As global emergency care grows, practical and effective performance measures are needed to ensure high quality care. Our objective was to systematically catalog and classify metrics that have been used to measure the quality of emergency care in resource-limited settings. METHODS We searched MEDLINE, Embase, CINAHL, and the gray literature using standardized terms. The references o...

Abstract Aim The COVID-19 pandemic has brought innumerable challenges to surgical training, especially with regard theatre opportunities for core trainees. This study aims evaluate the implementation of training-oriented key performance indicators (KPIs) in supporting trainees meet Joint Committee on Surgical Training (JCST) quality training. Method A six-month long closed-loop improvement proj...

We study fairness in house allocation, where $m$ houses are to be allocated among $n$ agents so that every agent receives one house. show maximizing the number of envy-free is hard approximate within a factor $n^{1-\gamma}$ for any constant $\gamma>0$, and exact version NP-hard even binary utilities. Moreover, we prove deciding whether proportional allocation exists computationally hard, wherea...

An inclusive curriculum anticipates and provides strategies to support a diverse range of learners. Universal Design for Learning (UDL) offers medical educators three core principles, which can be used design objectives, activities, instructional materials, assessments with embedded flexibility, equitability, representation Drawing on the available literature author experience, this article pre...

Knowledge elaboration plays a critical role in promoting knowledge acquisition and facilitating the retention of target knowledge in online collaborative discussions. Adopting a key-term-based automated analysis approach, we proposed an indicator framework to measure the level of knowledge elaboration in terms of coverage, activation, and equitability. An interactive web-based tool was develope...

We consider the problem of selecting fair divisions of a heterogeneous divisible good among a set of agents. Recent work (Cohler et al., AAAI 2011) focused on designing algorithms for computing optimal—social welfare maximizing (maxsum)—allocations under the fairness notion of envyfreeness. Maxsum allocations can also be found under alternative notions such as equitability. In this paper, we as...
