How Parenting Style Influences Children: A Review of Controlling, Guiding, and Permitting Parenting Styles on Children’s Behavior, Risk- Taking, Mental Health, and Academic Achievement

Across cultures, parenting styles fall into three categories based on levels of demandingness and responsiveness. This literature review examines three categories of parenting styles and their influence on children’s behavior, risk-taking, mental health, and academic achievement. Controlling parents are high on demandingness and low on responsiveness (Baumrind, 1991; Kim, in press). Guiding parents are high on demandingness and high on responsiveness (Baumrind, 1991; Kim, in press). Permitting parents are low on demandingness and low on responsiveness (Baumrind, 1991; Kim, in press). Based on positive and negative effects of each parenting style, this review concludes that the guiding parenting style is the most effective for children. Implications for parents include recognizing the need to provide both support and structure for children

The Closest View of a Fast Coronal Mass Ejection: How Faulty Assumptions near Perihelion Lead to Unrealistic Interpretations of PSP/WISPR Observations

We report on the closest view of a coronal mass ejection observed by the Parker Solar Probe (PSP)/Wide-field Imager for {Parker} Solar PRobe (WISPR) instrument on September 05, 2022, when PSP was traversing from a distance of 15.3~to~13.5~R$_\odot$ from the Sun. The CME leading edge and an arc-shaped {\emph{concave-up} structure near the core} was tracked in WISPR~field of view using the polar coordinate system, for the first time. Using the impact distance on Thomson surface, we measured average speeds of CME leading edge and concave-up structure as $\approx$2500~$\pm$~270\,km\,s$^{-1}$ and $\approx$400~$\pm$~70\,km\,s$^{-1}$ with a deceleration of $\approx$20~m~s$^{-2}$ for the later. {The use of the plane-of-sky approach yielded an unrealistic speed of more than three times of this estimate.} We also used single viewpoint STEREO/COR-2A images to fit the Graduated Cylindrical Shell (GCS) model to the CME while incorporating the source region location from EUI of Solar Orbiter and estimated a 3D speed of $\approx$2700\,km\,s$^{-1}$. We conclude that this CME exhibits the highest speed during the ascending phase of solar cycle 25. This places it in the category of extreme speed CMEs, which account for only 0.15\% of all CMEs listed in the CDAW CME catalog.Comment: 13 Pages, 6 Figures; Accepted in The Astrophysical Journal Letter

Parker Solar Probe Imaging of the Night Side of Venus

We present images of Venus from the Wide-Field Imager for Parker Solar Probe (WISPR) telescope on board the Parker Solar Probe (PSP) spacecraft, obtained during PSP's third and fourth flybys of Venus on 2020 July 11 and 2021 February 20, respectively. Thermal emission from the surface is observed on the night side, representing the shortest wavelength observations of this emission ever, the first detection of the Venusian surface by an optical telescope observing below 0.8 μm. Consistent with previous observations at 1 μm, the cooler highland areas are fainter than the surrounding lowlands. The irradiances measured by WISPR are consistent with model predictions assuming a surface temperature of T = 735 K. In addition to the thermal emission, the WISPR images also show bright nightglow emission at the limb, and we compare the WISPR intensities with previous spectroscopic measurements of the molecular oxygen nightglow lines from Venus Express

Stroke in children with posterior fossa brain malformations, hemangiomas, arterial anomalies, coarctation of the aorta and cardiac defects, and eye abnormalities (PHACE) syndrome: a systematic review of the literature.

Background and purposePHACE is an acronym for posterior fossa brain malformations, hemangiomas, arterial anomalies, coarctation of the aorta and cardiac defects, and eye abnormalities. Several case reports of arterial ischemic stroke (AIS) in individuals with PHACE have been published, but risk factors for AIS in PHACE have not been clearly defined. The objective of this article is to review all cases of stroke in PHACE in children and describe clinical characteristics that may be associated with an increased risk of AIS.MethodsA literature and registry search was conducted to identify patients with PHACE who had experienced AIS. Data were analyzed to determine age of onset, presenting signs and symptoms, and clinical features among this cohort compared with PHACE without AIS.ResultsTwenty-two individuals with PHACE and AIS were identified. Imaging of the arteries of the head and neck was reported in 20 of 22. Narrowing or nonvisualization of at least 1 great cerebral vessel was present in 19 of 20 and of those, 15 had ≥ 2 vessels involved. Aortic arch anomalies were reported in 13 of 22 individuals.ConclusionsAplasia, hypoplasia, or occlusion of a major cerebral artery appears to be a significant risk factor for AIS in children with PHACE, especially when >1 vessel is involved or if there is coarctation of the aorta

Platelet ITAM signaling is critical for vascular integrity in inflammation

Platelets play a critical role in maintaining vascular integrity during inflammation, but little is known about the underlying molecular mechanisms. Here we report that platelet immunoreceptor tyrosine activation motif (ITAM) signaling, but not GPCR signaling, is critical for the prevention of inflammation-induced hemorrhage. To generate mice with partial or complete defects in these signaling pathways, we developed a protocol for adoptive transfer of genetically and/or chemically inhibited platelets into thrombocytopenic (TP) mice. Unexpectedly, platelets with impaired GPCR signaling, a crucial component of platelet plug formation and hemostasis, were indistinguishable from WT platelets in their ability to prevent hemorrhage at sites of inflammation. In contrast, inhibition of GPVI or genetic deletion of Clec2, the only ITAM receptors expressed on mouse platelets, significantly reduced the ability of platelets to prevent inflammation-induced hemorrhage. Moreover, transfusion of platelets without ITAM receptor function or platelets lacking the adapter protein SLP-76 into TP mice had no significant effect on vascular integrity during inflammation. These results indicate that the control of vascular integrity is a major function of immune-type receptors in platelets, highlighting a potential clinical complication of novel antithrombotic agents directed toward the ITAM signaling pathway
