Afraid in the hospital: Parental concern for errors during a child's hospitalization

OBJECTIVE: (1) To determine the proportion of parents concerned about medical errors during a child's hospitalization; and (2) the association between this concern and parental self-efficacy with physician interactions. STUDY DESIGN: Cross-sectional survey. SETTING: Tertiary care children's hospital. PARTICIPANTS: Parents of children admitted to the general medical service. OUTCOME MEASURE: Parental concern about medical errors. METHODS: Parents were asked their agreement with the statement “When my child is in the hospital I feel that I have to watch over the care that he/she is receiving to make sure that mistakes aren't made.” We used multivariate logistic regression to examine the association between parents' self-efficacy with physician interactions and the need “to watch over a child's care,” adjusting for parent and child demographics, English proficiency, past hospitalization, and social desirability bias. RESULTS: Of 278 eligible parents, 130 completed surveys and 63% reported the need to watch over their child's care to ensure that mistakes were not made. Parents with greater self-efficacy with physician interactions were less likely to report this need (odds ratio [OR], 0.83; 95% confidence interval [CI], 0.72-0.92). All parents who were “very uncomfortable” communicating with doctors in English reported the need to watch over their child's care to prevent mistakes. CONCLUSIONS: Nearly two-thirds of surveyed parents felt the need to watch over their child's hospital care to prevent mistakes. Parents with greater self-efficacy with physician interactions were less likely to report the need to watch over their child's care while parents with lower English proficiency were more likely to report this need.

PHYSIOLOGICAL AND MORPHOLOGICALSTUDY OF CROTON TIGLIUM LEAVES EXPOSED TO DIFFERENT LIGHT CONDITIONS

ABSTRACT: In this study we have taken Croton tiglium to study the effect of different light conditions on the physiological and morphological appreance of the plant. Croton tigliumis an ornamental plant used for the interior and garden decoration, belongs to the family Euphorbiaceae, is one of the most popular ornamental plants because of vivid foliage colours and varied leaf shapes. When it is allowed to grow under different light conditions and tested by various parameters like Chlorophyll and Carotenoid Content, Leaf Area and Specific Leaf Weight, Light Microscopy, statistical analysis etc the results shows Low light intensities (LLI) increases the concentration of chla and chlb while high light intensities (HLI) on the otherhand reduces the level of chlaand chlbin the leaves of Croton tiglium

At-Most-Hexa Meshes

AbstractVolumetric polyhedral meshes are required in many applications, especially for solving partial differential equations on finite element simulations. Still, their construction bears several additional challenges compared to boundary‐based representations. Tetrahedral meshes and (pure) hex‐meshes are two popular formats in scenarios like CAD applications, offering opposite advantages and disadvantages. Hex‐meshes are more intricate to construct due to the global structure of the meshing, but feature much better regularity, alignment, are more expressive, and offer the same simulation accuracy with fewer elements. Hex‐dominant meshes, where most but not all cell elements have a hexahedral structure, constitute an attractive compromise, potentially unlocking benefits from both structures, but their generality makes their employment in downstream applications difficult. In this work, we introduce a strict subset of general hex‐dominant meshes, which we term 'at‐most‐hexa meshes', in which most cells are still hexahedral, but no cell has more than six boundary faces, and no face has more than four sides. We exemplify the ease of construction of at‐most‐hexa meshes by proposing a frugal and straightforward method to generate high‐quality meshes of this kind, starting directly from hulls or point clouds, for example, from a 3D scan. In contrast to existing methods for (pure) hexahedral meshing, ours does not require an intermediate parameterization of other costly pre‐computations and can start directly from surfaces or samples. We leverage a Lloyd relaxation process to exploit the synergistic effects of aligning an orientation field in a modified 3D Voronoi diagram using the norm for cubical cells. The extracted geometry incorporates regularity as well as feature alignment, following sharp edges and curved boundary surfaces. We introduce specialized operations on the three‐dimensional graph structure to enforce consistency during the relaxation. The resulting algorithm allows for an efficient evaluation with parallel algorithms on GPU hardware and completes even large reconstructions within minutes

Strategies to achieve adequate vitamin A intake for young children: options for Cameroon.

Meeting children's vitamin A (VA) needs remains a policy priority. Doing so efficiently is a fiscal imperative and protecting at-risk children during policy transitions is a moral imperative. Using the Micronutrient Intervention Modeling tool and data for Cameroon, we predict the impacts and costs of alternative VA intervention programs, identify the least-cost strategy for meeting targets nationally, and compare it to a business-as-usual (BAU) strategy over 10 years. BAU programs effectively cover ∼12.8 million (m) child-years (CY) and cost ∼$30.1 m; ∼US$2.34 per CY effectively covered. Improving the VA-fortified oil program, implementing a VA-fortified bouillon cube program, and periodic VA supplements (VAS) in the North macroregion for 3 years effectively cover ∼13.1 m CY at a cost of ∼US$9.5 m, or ∼US$0.71 per CY effectively covered. The tool then identifies a sequence of subnational policy choices leading from the BAU toward the more efficient strategy, while addressing VA-attributable mortality concerns. By year 4, fortification programs are predicted to eliminate inadequate VA intake in the South and Cities macroregions, but not the North, where VAS should continue until additional delivery platforms are implemented. This modeling approach offers a concrete example of the strategic use of data to follow the Global Alliance for VA framework and do so efficiently

Studying excited-state-specific perturbation theory on the Thiel set

We explore the performance of a recently-introduced $N^5$-scaling excited-state-specific second order perturbation theory (ESMP2) on the singlet excitations of the Thiel benchmarking set. We find that, without regularization, ESMP2 is quite sensitive to $\pi$ system size, performing well in molecules with small $\pi$ systems but poorly in those with larger $\pi$ systems. With regularization, ESMP2 is far less sensitive to $\pi$ system size and shows a higher overall accuracy on the Thiel set than CC2, EOM-CCSD, CC3, and a wide variety of time-dependent density functional approaches. Unsurprisingly, even regularized ESMP2 is less accurate than multi-reference perturbation theory on this test set, which can in part be explained by the set's inclusion of some doubly excited states but none of the strong charge transfer states that often pose challenges for state-averaging. Beyond energetics, we find that the ESMP2 doubles norm offers a relatively low-cost way to test for doubly excited character without the need to define an active space

Image Fusion Techniques and Applications: A Review

Image fusion is characterized as the way toward joining at least two unique images into another single image holding imperative components from every image with amplified data content. The aftereffect of image fusion is another image which is more appropriate for human and machine discernment or further image handling undertakings, for example, division, highlight extraction and protest acknowledgment. This paper presents survey on a portion of the image fusion systems i.e. basic normal, basic most extreme, PCA, DCT, DWT. Similar investigation of every one of these strategies reasons that DWT is better approach

Freeze-out dynamics via charged kaon femtoscopy in √ sNN = 200 GeV central Au + Au collisions

We present measurements of three-dimensional correlation functions of like-sign, low-transverse-momentum kaon pairs from √sNN=200 GeV Au+Au collisions. A Cartesian surface-spherical harmonic decomposition technique was used to extract the kaon source function. The latter was found to have a three-dimensional Gaussian shape and can be adequately reproduced by Therminator event-generator simulations with resonance contributions taken into account. Compared to the pion one, the kaon source function is generally narrower and does not have the long tail along the pair transverse momentum direction. The kaon Gaussian radii display a monotonic decrease with increasing transverse mass mT over the interval of 0.55≤mT≤1.15 GeV/c2. While the kaon radii are adequately described by the mT -scaling in the outward and sideward directions, in the longitudinal direction the lowest mT value exceeds the expectations from a pure hydrodynamical model prediction

Support for early career astronomers who are just beginning to explore astronomy research is imperative to increase retention of diverse practitioners in the field. Since 2010, Astrobites has played an instrumental role in engaging members of the community -- particularly undergraduate and graduate students -- in research. In this white paper, the Astrobites collaboration outlines our multi-faceted online education platform that both eases the transition into astronomy research and promotes inclusive professional development opportunities. We additionally offer recommendations for how the astronomy community can reduce barriers to entry to astronomy research in the coming decade

Performance of prototypes for the ALICE electromagnetic calorimeter

The performance of prototypes for the ALICE electromagnetic sampling calorimeter has been studied in test beam measurements at FNAL and CERN. A $4\times4$ array of final design modules showed an energy resolution of about 11% /$\sqrt{E(\mathrm{GeV})}$ $\oplus$ 1.7 % with a uniformity of the response to electrons of 1% and a good linearity in the energy range from 10 to 100 GeV. The electromagnetic shower position resolution was found to be described by 1.5 mm $\oplus$ 5.3 mm /$\sqrt{E \mathrm{(GeV)}}$. For an electron identification efficiency of 90% a hadron rejection factor of $>600$ was obtained.Comment: 10 pages, 10 figure
