Emotional intelligence as a moderator of problem based arousal on solution quality and quantity

The study examined the interactive influence o f the affective qualities of a problem and a problem solver’s emotional intelligence (El), an individual difference in the ability to perceive, express, integrate, understand, and regulate emotion, on the quality and quantity of solutions generated to two different ill-structured problems. The general hypothesis was that emotional intelligence would moderate the effect of the negative emotional arousal of a problem controlling for the influence of cognitive intelligence, such that the discrepancy between those higher and lower in emotional intelligence would be greater for the problem which is high in emotional arousal than for the problem which is low. Emotional intelligence would provide a greater advantage to generating higher quality solutions for the high emotional arousal problem. High negative emotional arousal was thought to restrict the quantity and quality of solutions. The study required that 99 participants generate solutions to two ill-structured problems, one high and one low in negative emotional arousal. The solutions were evaluated in terms of resolving power, or the extent to which the solution addressed the conflicting aspects of the problem. Results did not support the interactive effect of El and negative emotional arousal. In addition, participants generated more solutions to the high negative arousal problem than to the low negative arousal problem. However, EI was found to predict the average resolving power of solutions generated across both problems. Exploratory analyses indicated that a people who are better at managing their emotions had a higher rated highest resolving power solution that those were less skilled in managing their emotions. Though results were largely unsupportive of the predictions, this study provided evidence for the influence of the affective qualities of a problem on the quality and quantity of solutions generated by problem solvers. In addition, organizations should consider both the qualities of the decision maker and the problem when choosing who will be involved in decision making endeavors

Multiple deficiencies of mitochondrial DNA- and nuclear-encoded subunits of respiratory NADH dehydrogenase detected with peptide- and subunit-specific antibodies in mitochondrial myopathies

AbstractAntibodies have been raised against synthetic peptides corresponding to several computer-predicted epitopes of three mtDNA-encoded subunits, ND4, ND5 and ND6, of the human respiratory chain NADH dehydrogenase (Complex I). Antibodies were characterized by a sensitive immunoblotting assay using proteins from human skeletal muscle mitochondria and by immunoprecipitation of radio-labeled HeLa cell mitochondrial translation products. Only antibodies against two of six selected peptides of the ND4 subunit, i.e., the C-terminal peptide and an internal peptide close to the C-terminus, reacted in both assays with the subunit. Antibodies raised against an internal peptide close to the N-terminus of the ND5 subunit and antibodies raised against an internal epitope of the ND6 subunit also reacted in both the immunoblotting and immunoprecipitation assays. The antibodies described above and other Complex I subunit- or holoenzyme-specific antibodies were used to investigate the subunit deficiencies of the respiratory NADH dehydrogenase in the skeletal muscle of patients affected by mitochondrial myopathies associated with Complex I defects. The reduction in enzyme activity correlated in an immunoblot assay with a decrease of four mtDNA-encoded subunits of the enzyme, as well as with a decrease of other subunits of Complex I encoded in the nDNA. The present work provides the first evidence of a decrease in NADH dehydrogenase subunits encoded in the mitochondrial genome in myopathy patients

Effects of local meteorology and aerosols on ozone and nitrogen dioxide retrievals from OMI and pandora spectrometers in Maryland, USA during DISCOVER-AQ 2011

An analysis is presented for both ground- and satellite-based retrievals of total column ozone and nitrogen dioxide levels from the Washington, D.C., and Baltimore, Maryland, metropolitan area during the NASA-sponsored July 2011 campaign of Deriving Information on Surface COnditions from Column and VERtically Resolved Observations Relevant to Air Quality (DISCOVER-AQ). Satellite retrievals of total column ozone and nitrogen dioxide from the Ozone Monitoring Instrument (OMI) on the Aura satellite are used, while Pandora spectrometers provide total column ozone and nitrogen dioxide amounts from the ground. We found that OMI and Pandora agree well (residuals within ±25 % for nitrogen dioxide, and ±4.5 % for ozone) for a majority of coincident observations during July 2011. Comparisons with surface nitrogen dioxide from a Teledyne API 200 EU NOx Analyzer showed nitrogen dioxide diurnal variability that was consistent with measurements by Pandora. However, the wide OMI field of view, clouds, and aerosols affected retrievals on certain days, resulting in differences between Pandora and OMI of up to ±65 % for total column nitrogen dioxide, and ±23 % for total column ozone. As expected, significant cloud cover (cloud fraction \u3e0.2) was the most important parameter affecting comparisons of ozone retrievals; however, small, passing cumulus clouds that do not coincide with a high (\u3e0.2) cloud fraction, or low aerosol layers which cause significant backscatter near the ground affected the comparisons of total column nitrogen dioxide retrievals. Our results will impact post-processing satellite retrieval algorithms and quality control procedures

Embedding clinical interventions into observational studies

Novel approaches to observational studies and clinical trials could improve the cost-effectiveness and speed of translation of research. Hybrid designs that combine elements of clinical trials with observational registries or cohort studies should be considered as part of a long-term strategy to transform clinical trials and epidemiology, adapting to the opportunities of big data and the challenges of constrained budgets. Important considerations include study aims, timing, breadth and depth of the existing infrastructure that can be leveraged, participant burden, likely participation rate and available sample size in the cohort, required sample size for the trial, and investigator expertise. Community engagement and stakeholder (including study participants) support are essential for these efforts to succeed

Neuregulin-1 enhances cell-cycle activity, delays cardiac fibrosis, and improves cardiac performance in rat pups with right ventricular pressure load

Objectives: Right ventricular (RV) failure is a leading cause of death in patients with congenital heart disease. RV failure is kept at bay during childhood. Limited proliferation of cardiomyocytes is present in the postnatal heart. We propose that cardiomyocyte proliferation improves RV adaptation to pressure load (PL). We studied adaptation in response to increased RV PL and the role of increased cardiomyocyte cell cycle activity (CCA) in rat pups growing into adulthood. Methods: We induced RV PL at day of weaning in rats (3 weeks; 30-40 g) by pulmonary artery banding and followed rats into adulthood (300 g). We performed histological analyses and RNA sequencing analysis. To study the effects of increased cardiomyocyte cell cycle activity, we administered neuregulin-1 (NRG1), a growth factor involved in cardiac development. Results: PL induced an increase in CCA, with subsequent decline of CCA (sham/PL at 4 weeks: 0.14%/0.83%; P = .04 and 8 weeks: 0.00%/0.00%; P = .484) and cardiac function (cardiac index: control/PL 4 weeks: 4.41/3.29; P = .468 and 8 weeks: 3.57/1.44; P = .024). RNA sequencing analysis revealed delayed maturation and increased CCA pathways. NRG1 stimulated CCA (PL vehicle/NRG1 at 2 weeks: 0.62%/2.28%; P = .003), improved cardiac function (cardiac index control vs vehicle/NRG1 at 2 weeks: 4.21 vs 3.07/4.17; P = .009/.705) and postponed fibrosis (control vs vehicle/NRG1 at 4 weeks: 1.66 vs 4.82%/2.97%; P = .009/.078) in RV PL rats during childhood. Conclusions: RV PL during growth induces a transient CCA increase. Further CCA stimulation improves cardiac function and delays fibrosis. This proof-of-concept study shows that stimulation of CCA can improve RV adaptation to PL in the postnatal developing heart and might provide a new approach to preserve RV function in patients with congenital heart disease.</p
