Abstract The psychological phenomenon of Parental Burnout (PB) results from an imbalance between continuous exposure to chronic parenting stress and available coping resources. study’s aim was examine relationships mothers’ perceived burden treatment PB, their ability utilize emotion work (EW) as a resource. Ninety-eight Israeli mothers (46 had children with special needs disabilities—W-SND, 52...
This letter introduces the concept of antifragile electronic warfare (EW), which we define as the ability to allow a communications link to improve performance due to the presence of a jammer. This concept should not be confused with jamming countermeasures (a.k.a. anti-jamming or electronic protection). Rather, antifragile EW can be thought of as the next step beyond simply avoiding or mitigat...
This study evaluated the effects of calf management system following early-weaning (EW) on performance of beef steers. On d 0, Brahman x British steers (n = 40; bodyweight [BW] = 198 ± 26 lb; age = 72 ± 14 d) were stratified by age and BW, and randomly assigned to normal-weaning (NW; d 177) or 1 of 3 EW treatments: 1) EW and grazed on ryegrass pastures for 67 d then on bahiagrass pastures until...
A 3-yr study used 16 cows and their spring-born calves (yr 1) and 48 first-calf heifers (yr 2, n = 24; yr 3, n = 24) and their spring-born calves in a completely randomized design. All cows and heifers were Angus x Beefmaster, and calves were sired by Angus bulls. Cow-calf pairs were assigned randomly to one of two management systems: 1) an early-weaning system, in which steer and heifer calves...
Gastric epithelial cells differentiate throughout the third postnatal week in rats, and become completely functional by weaning time. When suckling is interrupted by early weaning (EW), cell proliferation and differentiation change in the gastric mucosa, and regulatory mechanisms might involve corticosterone activity. Here we used EW and RU486 (glucocorticoid receptor antagonist) to investigate...
Determination of absolute surface coverage with sub-monolayer sensitivity is demonstrated using evanescent-wave cavity ring-down spectroscopy (EW-CRDS) and conventional CRDS by employing conservation of the absolute integrated absorption intensity between gas and adsorbed phases. The first C-H stretching overtones of trichloroethylene (TCE), cis-dichloroethylene, and trans-dichloroethylene are ...
The origin of the luminosity dependence of the equivalent width (EW) of broad emission lines in active galactic nuclei (AGN) – the Baldwin effect – is not firmly established yet. We explore this question for the broad C IV λ1549 line using the Boroson & Green sample of the 87 z 0.5 Bright Quasar Survey (BQS) quasars. Useful UV spectra of the C IV region are available for 81 of the objects, whic...
Iron Kα emission from photoionized and optically thick material is observed in a variety of astrophysical environments including X-ray binaries, active galactic nuclei, and possibly gamma-ray bursts. This paper presents calculations showing how the equivalent width (EW) of the Fe Kα line depends on the iron abundance of the illuminated gas and its ionization state – two variables subject to sig...
Three White Leghorn strains, their two-way crosses, and two commercial lines were used to study the effects of aging on several parameters related to performance of fitness and nonfitness traits during the first laying cycle of hens housed three per cage. Egg number of the survivors (EPF) and egg number including mortality and morbidity (EPM) were divided into 12 periods of 28 d each, starting ...
PURPOSE This randomized controlled trial examined the quality-of-life benefits of an expressive writing (EW) intervention for patients with renal cell carcinoma (RCC) and identified a potential underlying mechanism of intervention efficacy. PATIENTS AND METHODS Patients (N = 277) with stage I to IV RCC were randomly assigned to write about their deepest thoughts and feelings regarding their c...
