Intersectional scholarship & positive youth development: Post-modern paradigm shift in understanding adjustment of marginalized youth
2016
Research on intersectionality of marginalized youth is generally situated in the assumption that non-normative identity leads to pathology and victimization. Further, most research to date has studied marginalized youth using a traditional nuclear family paradigm. In this paper we discuss how intersectionality addresses the combination of strengths and challenges of living with stigmatizing identities and family processes, towards developing successful youth adjustment. We apply the three-step intersectionality approach to study findings among a group of racial/ethnic minority and sexual minority identified youth and discuss the particular role of familism and extended kinship support belie…
Relationships between pollutant emissions from vehicles and levels of concentrations: a phenomenological approach
2005
The level of air quality in urban centres is affected by emission of several pollutants, mainly coming from the vehicles flowing in their road networks. This is a well known phenomenon that influences the quality of life of people. Despite the deep concern of researchers and technicians, we are far from a total understanding of this phenomenon. On the contrary, the availability of reliable forecasting models would constitute an important tool for administrators in order of assessing suitable actions concerning the transportation policies, public as well private. As matter of fact, the definition of a physical model requires the knowledge of many parameters, involving the running fleet, the …
A theoretical study on the thermal ring opening rearrangement of 1H-bicyclo[3.1.0]hexa-3,5-dien-2-one: a case of two state reactivity
2009
The molecular mechanism of the thermal rearrangement of singlet 1H-bicyclo[3.1.0]hexa-3,5-dien-2-one to give triplet 4-oxocyclohexa-2,5-dienylidene has been investigated using density functional theory (B3LYP and M05-2X functionals) as well as ab initio CASSCF and CASPT2 multiconfigurational methods. The reactant has a singlet ground state while the product can be found in three low lying electronic states P((3)B(1)), P((1)B(1)), and P((1)A'). Therefore, the molecular mechanism of this ring opening rearrangement may involve up to three different potential energy surfaces of two spin multiplicities: two singlet (closed shell, CS, and open shell, OS) and one triplet. The stationary points on …
On the K-stability of complete intersections in polarized manifolds
2011
We consider the problem of existence of constant scalar curvature Kaehler metrics on complete intersections of sections of vector bundles. In particular we give general formulas relating the Futaki invariant of such a manifold to the weight of sections defining it and to the Futaki invariant of the ambient manifold. As applications we give a new Mukai-Umemura-Tian like example of Fano 5-fold admitting no Kaehler-Einstein metric and a strong evidence of K-stability of complete intersections on Grassmannians.
The doodle of a finitely determined map germ from R2 to R3
2009
Let f:U⊂R2→R3 be a representative of a finitely determined map germ f:(R2,0)→(R3,0). Consider the curve obtained as the intersection of the image of the mapping f with a sufficiently small sphere Sϵ2 centered at the origin in R3, call this curve the associated doodle of the map germ f. For a large class of map germs the associated doodle has many transversal self-intersections. The topological classification of such map germs is considered from the point of view of the associated doodles.
Intersection of Serious Games and Learning Motivation for Medical Education
2020
Educational scholars are implementing technologies into the educational process. They use virtual reality, simulations, augmented reality and other immersive technologies that provide entertainment and an interesting, immersive environment as well as engage and motivate students. The aim of this research is to understand the scope and the nature of studies where serious games for medical education are prospective research subjects for the development of learning motivation. There are specific research questions that are of interest to the authors: (1) how many studies are devoted to exploring how serious games and simulations develop learning motivation; (2) how many studies are devoted to …
Dissertation: “In the intersection of television and Twitter : Social television as a tool for interaction and participation in a media event”
2020
This dissertation presents the phenomenon of social television by focusing on the interplay between the traditional broadcast media and the newer social media in the context of the FIFA World Cup. The aim of the study is to shed light on interactional practices that are generated in the intersection of television and Twitter. Through the lens of digital discourse and conversation analysis the study examines how the participation in a media event is constructed in live tweeting practices. The dissertation shows that social media have offered new ways of participating and enjoying television content but have not replaced the role of traditional television as a central medium for experiencing …
The Bruce–Roberts Number of A Function on A Hypersurface with Isolated Singularity
2020
AbstractLet $(X,0)$ be an isolated hypersurface singularity defined by $\phi \colon ({\mathbb{C}}^n,0)\to ({\mathbb{C}},0)$ and $f\colon ({\mathbb{C}}^n,0)\to{\mathbb{C}}$ such that the Bruce–Roberts number $\mu _{BR}(f,X)$ is finite. We first prove that $\mu _{BR}(f,X)=\mu (f)+\mu (\phi ,f)+\mu (X,0)-\tau (X,0)$, where $\mu $ and $\tau $ are the Milnor and Tjurina numbers respectively of a function or an isolated complete intersection singularity. Second, we show that the logarithmic characteristic variety $LC(X,0)$ is Cohen–Macaulay. Both theorems generalize the results of a previous paper by some of the authors, in which the hypersurface $(X,0)$ was assumed to be weighted homogeneous.
Inverted energy gap law for the nonradiative decay in fluorescent floppy molecules: larger fluorescence quantum yields for smaller energy gaps
2019
A data survey on experimental fluorescence quantum yields of (multi)substituted dicyano-distyrylbenzenes in fluid solution evidences that non-radiative decay increases with the Franck-Condon energy (E-FC), being opposite to the conventional energy gap law. Quantum-chemistry indicates that this is controlled by access to the conical intersection (CI) following the Bell-Evans-Polanyi principle as a first-step approximation for this family of molecules; the variations in E-FC among the different compounds are found to be decisive, while those of E-CI are estimated to be weaker or even enhancing the effect. The current findings may have significant consequences for the design of molecules for o…
