Research Directions in Cyber Physical Systems

Cyber Physical systems (CPS) connect the physical world with cyber world. The events happening in the real world is enormous and most of it go unnoticed and information is lost. CPS enables to embed tiny smart devices to capture the data and send it to Internet for further processing. The entire set-up call for lots of challenges and open new research problems. This talk is a journey through the landscape of research problems in this emerging area.

Cyber-Mobbing

„Cyber-Mobbing-Tod eines Teenagers“ titelt Spiegel-Online 2007: auch auf Stern.de (2009) findet sich die Meldung: „15-jährige tötet sich nach Cyber-Mobbing“, Zeit Online (2009) berichtet ebenfalls über diesen Vorfall. In Deutschland sind bisher keine derartigen Extremfälle öffentlich bekannt, dennoch ist das Phänomen, vermutlich veranlasst durch diese oder ähnliche Vorfälle, in das Interesse der medialen Öffentlichkeit gerückt. Diese Arbeit geht daher der Frage auf den Grund, ob Cyber-Mobbing auch ein Problem an deutschen Schulen ist und in welchem Ausmaß es dort auftritt. Im Fokus stehen jedoch nicht die genannten Extremfälle, da sie glücklicherweise eher eine Seltenheit darstellen, sondern alltägliche Formen des Cyber-Mobbings, weil genau hier der Grundstein für solch furchtbare Ereignisse gelegt wird. Cyber-Mobbing ist ein recht neues und junges Phänomen, das noch nicht allzu lange im Fokus der wissenschaftlichen Welt steht. Daher gelten viele Facetten als noch nicht ausreichend erschlossen, um eindeutige Aussagen hinsichtlich bestimmter Kausalitäten zu machen. Eine Vielzahl der wissenschaftlichen Arbeiten orientiert sich daher am Konzept des Mobbings, um Unterschiede oder Gemeinsamkeiten zwischen diesen Spielarten der Gewalt herauszuarbeiten. Daher folgt die vorliegende Arbeit dieser Tradition in metaanalytischer Form, untersucht folglich bestehende Literatur und setzt diese in einen kausalen Zusammenhang. Leitend für die Literaturanalyse ist die Frage ob sich die Dimensionen schulischer Gewalt, in diesem Falle Mobbing, durch die neuen Kommunikationsmedien verändert haben. Die Beantwortung dieser Frage zielt primär darauf ab herauszufinden, ob Cyber-Mobbing ähnlichen Strukturen folgt, wie Mobbing oder aber spezifische Muster existieren und ob die Schüler, die in Cyber-Mobbing involviert sind, auch in Mobbing verwickelt sind oder von einer Verschiebung der Interaktionsmuster gesprochen werden kann. Handelt es sich bei Cyber-Mobbing also um eine neue Form des Mobbings, oder um ein eigenständiges und unabhängiges Phänomen?

The effect of Ponzi schemes on crime: Evidence from the colombian case

This paper estimates the impact of a massive negative income shock led by the simultaneous crash down of several Ponzi schemes (also known as financial ``pyramids"") in Colombia on crime rates at the municipal level. Using novel data on the spatial incidence of the latest wave of Colombian pyramids and their crash down date, I estimate difference-in-differences models with both monthly and yearly frequency. I find that the negative income shock of the pyramids" crash down differentially exacerbates crime in affected municipalities compared to those with no presence of Ponzi schemes. This is true for minor offenses like commercial theft or residential burglary, but not for major crimes as murder or terrorism.

Privacidad e intimidad en las interacciones virtuales

El presente trabajo es una revisión de la literatura de investigación en Ciberpsicología centrada en las categorías de privacidad, intimidad, identidad y vulnerabilidad, y en la forma como estas se desarrollan en las redes sociales virtuales. Los principales hallazgos indicaron que son los jóvenes quienes dedican gran parte de su tiempo a interactuar en dichas redes, y a su vez, dado el manejo que les dan, tienen mayor exposición ante los posibles riesgos de estas, como el matoneo, las conductas auto lesivas, la explotación sexual y los trastornos de la alimentación. Se describen estos riesgos y se proponen posibles soluciones.

The swindle crime: a necessary normative construction of its elements

The present work exposes a review about the performance of the “traditional” thesis(Naturalistic) of the swindle crime in front of the needs of the present’s Political Policy.For this system, the various frauds’ elements require a causal relationship. Today itmight be wondered whether this solution is desirable, i.e. whether respond efficientlyto the problematic assumptions that the contemporary business practices raises.

Neighborhood characteristics and the spatial concentration of crime: Evidence for Bogotá

Using a unique neighborhood crime dataset for Bogotá in 2011, this study uses a spatial econometric approach and examines the role of socioeconomic and agglomeration variables in explaining the variance of crime. It uses two different types of crime, violent crime represented in homicides and property crime represented in residential burglaries. These two types of crime are then measured in non-standard crime statistics that are created as the area incidence for each crime in the neighborhood. The existence of crime hotspots in Bogotá has been shown in most of the literature, and using these non-standard crime statistics at this neighborhood level some hotspots arise again, thus validating the use of a spatial approach for these new crime statistics. The final specification includes socioeconomic, agglomeration, land-use and visual aspect variables that are then included in a SARAR model an estimated by the procedure devised by Kelejian and Prucha (2009). The resulting coefficients and marginal effects show the relevance of these crime hotspots which is similar with most previous studies. However, socioeconomic variables are significant and show the importance of age, and education. Agglomeration variables are significant and thus more densely populated areas are correlated with more crime. Interestingly, both types of crimes do not have the same significant covariates. Education and young male population have a different sign for homicide and residential burglaries. Inequality matters for homicides while higher real estate valuation matters for residential burglaries. Finally, density impacts positively both crimes.

Incidencia de las agresiones a la seguridad cibernética en el desarrollo informático de las Fuerzas Armadas de Estados Unidos (2003-2013)

La presente investigación tiene como objetivo analizar la incidencia de las agresiones cibernéticas en el desarrollo informático de las Fuerzas Armadas de Estados Unidos. Los diferentes estudios que se han realizado sobre el ciberespacio se han enfocado en el papel del individuo como actor principal y se ha dejado de lado las repercusiones que éste ha tenido para el Estado, como un nuevo eje de amenazas. Teniendo en cuenta lo anterior, esta investigación demostrará a partir del concepto de securitización, que se busca priorizar la “ciberseguridad” dentro de la agenda del gobierno estadounidense. Al ser este un estudio que aborda experiencias concretas durante un periodo de tiempo de más de 10 años, el diseño metodológico de la investigación será longitudinal, ya que abarcará estudios, artículos, textos y resoluciones que se han realizado desde 2003 hasta la actualidad.

The crime kuznets curve

We document the existence of a Crime Kuznets Curve in US states since the 1970s. As income levels have risen, crime has followed an inverted U-shaped pattern, first increasing and then dropping. The Crime Kuznets Curve is not explained by income inequality. In fact, we show that during the sample period inequality has risen monotonically with income, ruling out the traditional Kuznets Curve. Our finding is robust to adding a large set of controls that are used in the literature to explain the incidence of crime, as well as to controlling for state and year fixed effects. The Curve is also revealed in nonparametric specifications. The Crime Kuznets Curve exists for property crime and for some categories of violent crime.
