Should Cyberbullying Be Criminalized?

Society’s attitudes towards all forms of bullying have changed in the last thirty years from considering it to be a normal part of childhood, a rite of passage and character building to regarding bullying as a behaviour to be prevented and condemned (Rigby, 2008; Žižek, 2008). This has been brought about by the research into the consequences of bullying during this time, revealing bullying to be detrimental not only to students who have been victimized but also to students who perpetrate the bullying and the bystanders who witness such behaviour. These consequences include increased levels of depression, anxiety and psychosomatic symptoms (Fekkes, Pijpers, Frediks, Vogels, & Verloove-Vanhorrick, 2006; Kim, Leventhal, Koh, Hubbard, & Boyce, 2006; Reijntjs, Kamphuis, Prinzie, & Telch, 2010) for those students who have been victimized. Different detrimental associations have been found for girls and boys who had been bullied in one longitudinal study (Carbone-Lopez, Esbensen, & Bick 2010); girls who had been indirectly bullied increased their drug use whereas boys did not, and while victimized girls showed lower self-esteem, this did not occur for boys.

Inhibitory plasticity balances excitation and inhibition in sensory pathways and memory networks

Cortical neurons receive balanced excitatory and inhibitory synaptic currents. Such a balance could be established and maintained in an experience-dependent manner by synaptic plasticity at inhibitory synapses. We show that this mechanism provides an explanation for the sparse firing patterns observed in response to natural stimuli and fits well with a recently observed interaction of excitatory and inhibitory receptive field plasticity. The introduction of inhibitory plasticity in suitable recurrent networks provides a homeostatic mechanism that leads to asynchronous irregular network states. Further, it can accommodate synaptic memories with activity patterns that become indiscernible from the background state but can be reactivated by external stimuli. Our results suggest an essential role of inhibitory plasticity in the formation and maintenance of functional cortical circuitry.

Inhibitory Synaptic Plasticity - Spike timing dependence and putative network function.

While the plasticity of excitatory synaptic connections in the brain has been widely studied, the plasticity of inhibitory connections is much less understood. Here, we present recent experimental and theoretical □ndings concerning the rules of spike timing-dependent inhibitory plasticity and their putative network function. This is a summary of a workshop at the COSYNE conference 2012.

Analytical phytoplankton carbon measurements spanning diverse ecosystems

The measurement of phytoplankton carbon (Cphyto) in the field has been a long-sought but elusive goal in oceanography. Proxy measurements of Cphyto have been employed in the past, but are subject to many confounding influences that undermine their accuracy. Here we report the first directly measured Cphyto values from the open ocean. The Cphyto samples were collected from a diversity of environments, ranging from Pacific and Atlantic oligotrophic gyres to equatorial upwelling systems to temperate spring conditions. When compared to earlier proxies, direct measurements of Cphyto exhibit the strongest relationship with particulate backscattering coefficients (bbp) (R2=0.69). Chlorophyll concentration and total particulate organic carbon (POC) concentration accounted for ~20% less variability in Cphyto than bbp. Ratios of Cphyto to Chl a span an order of magnitude moving across and within distinct ecosystems. Similarly, Cphyto:POC ratios were variable with the lowest values coming from productive temperate waters and the highest from oligotrophic gyres. A strong relationship between Cphyto and bbp is particularly significant because bbp is a property retrievable from satellite ocean color measurements. Our results, therefore, are highly encouraging for the global monitoring of phytoplankton biomass from space. The continued application of our Cphyto measurement approach will enable validation of satellite retrievals and contribute to an improved understanding of environmental controls on phytoplankton biomass and physiology.

Interaktives Musizieren : Beiträge zu einem deutschen Modellprojekt an Krankenhäusern und Pflegeeinrichtungen

Musikalische Darbietungen sind in Krankenhäusern und Pflegeeinrichtungen nichts Ungewöhnliches. Doch werden die vielfältigen psychosozialen Möglichkeiten, die das Medium Musik bietet, außerhalb therapeutischer Settings kaum zu einer intensiven zwischenmenschlichen Kommunikation genutzt. Diese Publikation soll einen Einblick in ein bundesweites Modellprojekt ermöglichen, das unter der Bezeichnung „Interaktives Musizieren“ in Hannover durchgeführt worden ist. Interaktives Musizieren bezeichnet eine unmittelbar gelebte musikalische Praxis, in der die Interaktionsmusizierenden, die Patientinnen und Patienten oder Bewohnerinnen und Bewohner sowie alle weiteren Anwesenden aufeinander bezogen sind. Die Interaktionsmusizierenden bereichern klangarme Umgebungen und schaffen Raum für zwischenmenschliche Begegnungen, die sie als einen außergewöhnlichen Moment gestalten. Damit bringen speziell ausgebildete Musikerinnen und Musiker neue ästhetisch-atmosphärische Impulse in Krankenhäuser und Pflegeeinrichtungen und verbessern die dortige Klang- und Lebenswelt. Das hier vorgestellte Modellprojekt „Interaktives Musizieren“ bietet eine Grundlage für verschiedene Einsatzformen von Musik in Feldern des Gesundheitswesens und der Sozialen Arbeit.
