Depression’s Connection to Self-Harming Behavior in Adolescents

Self-harming behavior amongst adolescents has increased in prevalence throughout America. There is a direct connection between depression and self-harming behaviors in adolescent students. The most common reasons why adolescents participate in self-injury are as a coping mechanism, a means of relief, for the regulation of feelings, self-punishment, attention seeking and sensation seeking. There is often a link between depressive symptoms and negative life events or past trauma. Multiple methods of self-harm are often performed by students and may be carried out several times over the course of many months, the techniques used vary greatly. Schools are one of the most important institutions that are in a position to help-self injurers. In this paper I will look at the causes, effects and possible preventative methods of self-injurious behavior

The Parametric Transition of Strange Matter Rings to a Black Hole

It is shown numerically that strange matter rings permit a continuous transition to the extreme Kerr black hole. The multipoles as defined by Geroch and Hansen are studied and suggest a universal behaviour for bodies approaching the extreme Kerr solution parametrically. The appearance of a `throat region', a distinctive feature of the extreme Kerr spacetime, is observed. With regard to stability, we verify for a large class of rings, that a particle sitting on the surface of the ring never has enough energy to escape to infinity along a geodesic.Comment: 16 pages, 11 figures, v3: minor changes so as to coincide with published versio

Complementarities in Innovation Policy

This paper develops a framework for testing discrete complementarities in innovation policy using European data on obstacles to innovation. We propose a discrete test of supermodularity in innovation policy leading to a number of inequality constraints. We apply our test to two types of innovation decisions: to innovate or not, and if so, by how much. We find that the evidence regarding the existence of complementarity in innovation policies depends on the phase of innovation that is targeted (getting firms innovative or increasing their innovation intensity) as well as on the particular pair of policies that is being considered. The two phases of the innovation process, i.e. the probability of becoming an innovator and the intensity of innovation, are subject to different constraints. Interestingly, there seems to be a need to adopt a package of policies to make firms innovate, while a more targeted choice among policies is necessary to make them more innovative. Nous développons dans cet article un cadre qui permette de tester des complémentarités dans les politiques d'innovation à partir de données européennes sur les obstacles à l'innovation. Nous proposons un test discret de supermodularité en matière de politique à l'innovation qui repose sur un certain nombre de contraintes d'inégalité. Nous appliquons ce test à deux types de décision d'innovation: innover ou non, et si oui de combien. Nous trouvons que l'existence de complémentarité en politique à l'innovation dépend de la phase d'innovation qu'on veut promouvoir (pousser les firmes à devenir innovantes ou à innover davantage) et de la paire de politiques qu'on considère. Les deux phases de l'innovation, la probabilité d'innover et l'intensité d'innovation, sont soumises à des contraintes différentes. Il est intéressant de constater qu'il semble y avoir un besoin d'adopter tout un ensemble de mesures pour rendre les firmes innovantes, alors qu'une politique plus ciblée sur l'une ou l'autre mesure est nécessaire pour les rendre plus innovantes.innovation policy, supermodularity, CIS 1, politiques d' innovation, supermodularité, CIS 1

On deflection fields, weak-focusing and strong-focusing storage rings for polar molecules

In this paper, we analyze electric deflection fields for polar molecules in terms of a multipole expansion and derive a simple but rather insightful expression for the force on the molecules. Ideally, a deflection field exerts a strong, constant force in one direction, while the force in the other directions is zero. We show how, by a proper choice of the expansion coefficients, this ideal can be best approximated. We present a design for a practical electrode geometry based on this analysis. By bending such a deflection field into a circle, a simple storage ring can be created; the direct analog of a weak-focusing cyclotron for charged particles. We show that for realistic parameters a weak-focusing ring is only stable for molecules with a very low velocity. A strong-focusing (alternating-gradient) storage ring can be created by arranging many straight deflection fields in a circle and by alternating the sign of the hexapole term between adjacent deflection fields. The acceptance of this ring is numerically calculated for realistic parameters. Such a storage might prove useful in experiments looking for an EDM of elementary particles.Comment: 8 pages, 5 figure
