Performance-related Funding of Universities – Does more Competition Lead to Grade Inflation? [PDF]

open access: yes
German universities are regarded as being under-financed, inefficient, and performing below average if compared to universities in other European countries and the US.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Elastic scattering spectroscopy accurately detects high grade dysplasia and cancer in Barrett's oesophagus [PDF]

open access: yes, 2006
Background and aims: Endoscopic surveillance of Barrett’s oesophagus currently relies on multiple random biopsies. This approach is time consuming, has a poor diagnostic yield, and significant interobserver variability. Elastic scattering spectroscopy is

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Grade Inflation at the University of Hawaii-Manoa [PDF]

open access: yes
I found that the University has experienced modest grade inflation over the past twelve years but the rate of inflation has been considerably low relative to other universities. In addition, I failed to find clear evidence of a widening interdepartmental

Promoting prenatal health care in poor rural areas through conditional cash transfers : evidence from JUNTOS in Peru [PDF]

open access: yes, 2017
The researchers assess the effects of JUNTOS, a conditional cash transfer program targeted to poor rural households in Peru, on the utilization of prenatal health care by women exposed to the program during their most recent pregnancy.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

The Impact of Alternative Grade Configurations on Student Outcomes through Middle and High School [PDF]

open access: yes
We use statewide administrative data from Florida to estimate the impact of attending public schools with different grade configurations on student achievement through grade 10. Based on an instrumental variable estimation strategy, we find that students
