At least nine hypotheses have been advanced to account for why many passerine species hatch their clutches asynchronously: 1) The brood reduction hypothesis; 2) The peak load reduction hypothesis; 3) The sibling rivalry reduction hypothesis; 4) The hurry-up hypothesis; 5) The egg viability hypothesis; 6) The sexual conflict hypothesis; 7) The equal investment hypothesis; 8) The nest failure hypoth
This article recapitulates the effect of my early fieldwork in socialist Romania, in which people's coping with bureaucracy through informal mechanisms of improvization, corruption, rumor creation, etc. come to mark by subsequent research interest, like a tatoo, and like the electronic ankle bracelet on the home prisoner, tend to pull me back into the same kind of theme, for better or for worse.

This paper argues that the concept of whistleblowing could best be understood as part of a larger regime of disclosure that includes personal revelations, truth-telling, leaking, informing, snitching and whistleblowing. Disclosure regimes are about knowledge that escapes. This paper discusses the conditions for this escaped knowledge and some of the consequences for organizations and communities.
Objective: To compare iron stores in infants born after elective caesarean section (CS) and a 30 s delay of umbilical cord clamping with those born vaginally after early (≤10 s) or delayed (≥180 s) cord clamping. Design: Prospective observational study with historical control. Setting: Swedish county hospital. Population: 64 infants born after elective CS were compared with a historical control of
Objective. To investigate the effect of delayed cord clamping (DCC) compared with early cord clamping (ECC) on maternal postpartum hemorrhage (PPH) and umbilical cord blood gas sampling. Design. Secondary analysis of a parallel-group, single-center, randomized controlled trial. Setting. Swedish county hospital. Population. 382 term deliveries after a low-risk pregnancy. Methods. Deliveries were ra
The heaviest currently known nuclei, which have up to 118 protons, have been produced in 48Ca induced reactions with actinide targets. Among them, the element tennessine (Ts), which has 117 protons, has been synthesized by fusing 48Ca with the radioactive target 249Bk, which has a half-life of 327 d. The experiment was performed at the gas-filled recoil separator TASCA. Two long and two short α de
It is a common belief that embedded expanding inclusions are subjected to an internal homogeneous compressive hydrostatic stress. Still, cracks that appear in precipitates that occupy a larger volume than the original material, are frequently observed. The appearance of cracks has since long been regarded as a paradox. In the present study it is shown that matrix materials that increases its volum
The fracture behaviour of ferritic/ferritic martensitic steels in Ductile to Brittle Transition (DBT) region is well captured by Master Curve approach, except in the upper region of transition due to ductile tearing prior to cleavage. The fracture toughness behavior in the upper region of DBT is generally censored by Master Curve. In this work the Master Curve approach is modified to extend its a
The assessment of fracture behaviour of ferritic/ferritic martensitic steels in Ductile to Brittle Transition (DBT) region iscrucial for shallower cracks. In this work the fracture behavior of In-RAFM steels isinvestigated with systematically varying a/W using Master Curve approach. This a/W effect is investigated using σ∗-V∗approach by calculating the active volume at simulated crack front. It i
