CaCu3Ti4O12: Low-Temperature Synthesis by Pyrolysis of an Organic Solution

Abstract: The giant-dielectric-constant material CaCu3Ti4O12 (CCTO) has been synthesized by pyrolyzing an organic solution containing stoichiometric amounts of the metal cations, which is done at lower temperature and shorter reaction time than the conventional solid-state reaction. A stable solution was prepared by dissolving calcium nitrate, copper(II) nitrate, and titanium(IV) isopropoxide in 2-methoxyethanol. This solution was pyrolyzed and heat-treated to achieve single-phase CCTO. The phases, microstructures, and dielectric properties of intermediate and final samples were characterized by X-ray diffraction, scanning electron microscopy, and dielectric spectroscopy.

The Effect of Emotional Intelligence and Task Type on Malevolent Creativity

Abstract: Malevolent creativity (MC), or intending to inflict harm in original ways, is an aspect of creativity that has received little empirical attention. It reasons that generating malevolently creative products in response to a problem is dependent upon individual differences and environmental factors, especially with regard to the social and emotional content of a particular problem. A personality variable strongly associated with how individuals acknowledge and respond to such social and emotional content is emotional intelligence (EI). Individuals with higher EI often solve problems in cooperative, beneficial, and positive ways, which seems contrary to solving a problem with MC. In addition to testing whether EI is negatively related to MC in general, we analyzed whether that negative relationship would persist even after controlling for cognitive ability and task effects. Those questions were examined across two studies. Results suggest that individuals with lower EI are more likely to respond to different types of problems with increased instances of MC even when the social or emotional content of those problems are factored out. The implications and limitations of these studies, as well as future directions for the study of MC, are discussed.

Clinical, neuropathological and genotypic variability in SNCA A53T familial Parkinson’s disease

Abstract: Individuals with familial Parkinson’s disease (PD) due to a monogenic defect can show considerable clinical and neuropathological variability To identify factors underlying this variability, histopathological analysis was performed in two clinically different A53T α-synuclein heterozygotes from Family H, a multigenerational α-synuclein A53T kindred To determine whether additional genetic factors could contribute to phenotypic variability, Family H and another multigenerational A53T kindred were analyzed for parkin polymorphisms We identified a previously described variant in parkin exon 4 associated with increased PD risk (S167N) The two A53T heterozygotes had markedly different neuropathology and different parkin genotypes: A N167 homozygote had early onset rapidly progressive disease, early dementia, myoclonus and sleep disorder, while a S167 homozygote had late onset, slowly progressive disease and late dementia Both had brainstem, cortical, and intraneuritic Lewy bodies (LB) The N167 individual had widespread cortical neurofibrillary degeneration, while the S167 individual had only medial temporal lobe neurofibrillary degeneration The N167 individual had severe neuronal loss in CA2 associated with Lewy neurites (LN), while the S167 individual had severe neuronal loss in CA1 associated with TDP-43 immunoreactive neuronal inclusions These findings implicate TDP-43 in the pathology of familial PD and suggest that parkin may act as a modifier of the A53T α-synuclein phenotype of familial PD Furthermore, they suggest a mechanism by which a rare genetic variant that is associated with a minor increase of PD risk in the heterozygous state may, in the homozygous state, exacerbate a disease phenotype associated with a highly penetrant dominant allele

Poetry and Photography An Exploration into Expressive/Creative Qualitative Research

Abstract: This study explores the use of photography and poetry as tools of qualitative social research. The question guiding this exploration is how might the visual representation of reality (photography) ...
