The Association of Body Image Self-Discrepancy With Female Gender, Calorie-Restricted Diet, and Psychological Symptoms Among Healthy Junior High Scho…
2021
Background: Body image self-discrepancy reflects a preference for weight loss regardless of normal body size and is a distorted cognition that may be a precursor to eating disorders. The aim of this study was to investigate factors associated with body image self-discrepancy among healthy junior high school students in Japan.Method: This cross-sectional study was conducted at one junior high school in Saitama, Japan, in December 2016. After excluding obese participants (defined as 20% above their ideal weight), 304 students (mean age, 13.9years; n=181 girls, 59.5%) who fell into underweight (n=22, 7.2%) and normal weight categories were selected. Body image self-discrepancy was measured usi…
Brand bonding development through shopping experiences in branded boutiques
2017
Nowadays Brands generate additional sales via their own retail network, in particular their own boutiques where they propose a unique experience and enter directly in contact with their consumers. Brands provide consumers with an emblematic experience they can fully pilot in comparison with externalized distribution. - Experiential marketing being a strategic lever - These specific shopping experience can generate business, reinforce brand-image, brand-bonding and can also trigger the engagement of consumers who themselves actively participate to brand-building. This survey aims at measuring how the shopping experience in branded boutiques generates brand-bonding. One shall then understand …
Bmi1 and Cell of Origin Determinants of Brain Tumor Phenotype
2007
Glioblastomas frequently express oncogenic EGFR and loss of the Ink4a/Arf locus. Bmi1, a positive regulator of stem cell self renewal, may be critical to drive brain tumor growth. In this issue of Cancer Cell, Bruggeman and colleagues suggest that brain tumors with these molecular alterations can be initiated in both neural precursor and differentiated cell compartments in the absence of Bmi1; however, tumorigenicity is reduced, and tumors contain fewer precursor cells. Surprisingly, tumors appear less malignant when initiated in precursor cells. Bmi1-deficient tumors also had fewer neuronal lineage cells, suggesting a role for Bmi1 in determination of cell lineage and tumor phenotype.
Differential expression levels of Sox9 in early neocortical radial glial cells regulate the decision between stem cell maintenance and differentiation
2021
ABSTRACTRadial glial progenitor cells (RGCs) in the dorsal forebrain directly or indirectly produce excitatory projection neurons and macroglia of the neocortex. Recent evidence shows that the pool of RGCs is more heterogeneous than originally thought and that progenitor subpopulations can generate particular neuronal cell types. Using single cell RNA sequencing, we have studied gene expression patterns of two subtypes of RGCs that differ in their neurogenic behavior. One progenitor type rapidly produces postmitotic neurons, whereas the second progenitor remains relatively quiescence before generating neurons. We have identified candidate genes that are differentially expressed between thes…
Experimental Study of Central Baffle Flume
2019
In this paper, the hydraulics of a central baffle flume (CBF) were experimentally studied. Extensive experimental runs were carried out to highlight the effects of different geometrical parameters such as baffle length, contraction ratio, and the length of upstream and downstream guide walls. Two different approaches, i.e., the Π theorem of dimensional analysis coupled with the incomplete self-similarity theory and the energy balance equation, were applied to deduce the stage–discharge formula of a CBF characterized by different geometrical parameters. The stage–discharge relationship deduced by the dimensional analysis approach was more accurate than that obtained by the energy approach. F…
Capitolo VIII della Carta dell’ONU e modelli di azione militare regionale
2019
This contribution deals with relations between regional organizations and the UN Security Council under Chapter VIII of the UN Charter. In this respect, the most recent trends are a shift from subsidiarity to a more equal partnership between these two subjects. The two models of action by delegation or authorization of the Security Council are in fact autonomous. This is demonstrated by the preparatory works of the UN Charter and subsequent practice. The model of authorized regional action enriches the range of instruments that the United Nations Charter provides for the maintenance of peace and collective security.
Self-assembly in surfactant-based liquid mixtures: Bis(2-ethylhexyl)phosphoric acid/bis(2-ethylhexyl)amine systems
2010
Surfactant-based liquid mixtures constitute an interesting class of nanostructured materials with promising potential in specialized applications. Here, structural and conductometric properties of liquid mixtures composed of bis(2-ethylhexyl)amine (BEEA) and bis(2-ethylhexyl)phosphoric acid (HDEHP) have been thoroughly investigated with the aim to correlate structural features with system charge transport capability. The evolution of self-assembled local nanostructures with system composition has been investigated by FT-IR and XRD while the conductometric properties were probed by conventional AC complex impedance. Both pure components exhibit nano-segregation due to their amphiphilic natur…
Linear scaling exchange gradients for Hartree–Fock and hybrid density functional theory
2000
Abstract A new method is introduced which allows to form the exchange part of self-consistent field energy gradients in a way which scales linearly with molecular size for molecules with a non-vanishing HOMO–LUMO gap. This is not only important for Hartree–Fock but as well for the popular hybrid density functional theory methods. The method preserves the optimized integral-driven structure of conventional direct methods. Efficiency and scaling behavior of the new method are illustrated for DNA fragments.
General occurrence of polar twisted minima in the ionic singlet excited surfaces of polyenes
1982
Except for a few cases, the lowest closed shell SCF solutions for the twisted geometries of polyenes involves delocalized nonpolarized MO’s, and represents a meaningless mixture of radicalar gound state and ionic excited states. Higher (quasi) solutions allow a realistic approach of the polarized ionic states. Orthogonality to the radicalar ground state may be imposed without important loss of energy. Further extensive CI does not modify significantly the situation. These statements are illustrated through ab initio calculations of butadiene and hexatriene. This approach allows us to show that slight distortions stablize polar minima even in ’’homosymmetric’’ molecules such as all‐trans hex…
Cumulative Childhood Maltreatment and Non‐Suicidal Self‐Injury: the Mediating and Moderating Role of Perceived Social Support in a Sample of Universi…
2022
Non-suicidal self-injury (NSSI) in young adults is recognized as a major public health concern. Some studies have identi- fied cumulative childhood maltreatment (CCM) as a significant vulnerability factor for NSSI, although the nature of this association remains unclear. Specifically, some theorists have investigated the role of perceived social support (PSS), con- sidered an important factor closely associated with both CCM and NSSI. The aim of the current study was to simultaneously investigate the potential mediating and moderating role of PSS from family and friends in the association between CCM and NSSI in a university student sample. Participants were 474 students (73.4% female; Mage…
