Young people’s voices went unheard: the Brexit generational divide

One thing to emerge both on social media and on the streets after the referendum result was a clear generational divide in how people voted. CoVi ran a research and analysis exercise looking at why such a divide existed, and how it played out in the public debate during the referendum campaign. Caroline Macfarland and Katy Owen explain how older, male-dominated personalities dominated the campaign, which did not appeal to younger voters’ preference for issues-based political debate. They suggest how younger Remain voters can have a voice in the ensuing Brexit negotiations

Living with intimate partner violence: Effects on children

Trabajo fin de grado en EnfermeríaIntroducción: La violencia de pareja es un problema prevalente en todas las sociedades, y en ocasiones las víctimas no son únicamente los componentes de la pareja. En este estudio, se centrará la atención en los menores que conviven en un contexto de violencia de pareja, y las consecuencias que supone para estos mismos. Objetivo: Averiguar las repercusiones de la exposición a la violencia de pareja a nivel de salud física, salud mental, emocional y comportamental. Valorar el papel y el desarrollo del vínculo con el cuidador en este problema. Y valorar algunas diferencias por edad, género y etnicidad Metodología: Se realizó una revisión sistemática a través de una búsqueda en bases de datos PubMed, Cinhal, CUIDEN y Cochrane con lenguaje controlado. Resultados: La exposición a la violencia de pareja (VP) supone un factor negativo en el desarrollo cognitivo, en salud mental, salud física, desarrollo emocional y comportamental. Las repercusiones están mediadas por factores individuales como la edad de la exposición, la resiliencia y factores protectores ambientales como es el vínculo de los cuidadores. Y en algunos casos existen diferencias en las experiencias por género y etnia. Conclusión: Los menores expuestos a violencia de pareja sufren consecuencias negativas en su desarrollo. Estas consecuencias pueden ser apreciables por los enfermeros pediátricos, quienes se encuentran en contacto con la familia y el paciente. Identificarlo es el primer paso de la actuación para poder evitar las consecuencias, o por lo menos, aminorarlas.Introduction: Intimate partner violence (IPV) is a prevalent problem in society today. Victims of IPV are not only the components of the couple involved in the relationship,minors exposed to IPV are also victims. This narrative review will focus on the minors exposed to IPV and the consequences of this exposure. Objectives: To find out the repercussions of exposure to IPV in mental and physical health and in cognitive, emotional and behavioral development. To understand the development of parental attachment in the midst of this problem and how it mediates these consequences. And finally to ascertain if the differences in age, gender and ethnicities affect the overall outcome. Methodology: A narrative review was carried out by searching on PubMed, Cinhal, CUIDEN and Cochrane data bases with controlled language. Results: Exposure to IPV is a negative factor in cognitive, emotional and behavioral development and, in mental and physical health. These consequences are mediated by individual factors, such as age of exposure, resilience and other protective characteristics, like secure attachment. Some of these consequences are also influenced by gender and ethnicity. Conclusion: Minors exposed to IPV suffer negative outcomes in their overall development. These consequences can be observed by pediatric nurses, who are in contact with the child, family and immediate surroundings. Identifying these signals is the first step of the intervention process in order to prevent further negative consequences in their development

Neue Entwicklungen in der Pharmakotherapie der Kokainabhängigkeit

Zusammenfassung: Es zeichnen sich neue medikamentöse Behandlungsmöglichkeiten der Kokainabhängigkeit ab. So gelang es erstmals mit Disulfiram in einer randomisierten, kontrollierten Studie, den Kokainkonsum signifikant zu reduzieren. Im Oktober2003 startete in den USA eine Phase-IIb-Studie mit aktiver Immunisierung gegen Kokain, seit September2004 läuft in der Schweiz eine Behandlungsstudie mit Methylphenidat in Kombination mit kognitiver Verhaltenstherapie. Vigabatrin, Tiagabin, Selegilin und Topiramat haben sich in Pilotuntersuchungen als potenzielle Kandidatensubstanzen für die weitere klinische Prüfung empfohle

Impacts of the biomass producer or collector tax credit on Oregon's wood fuels market and economy

32 pagesOregon’s Biomass Producer or Collector (BPC) Tax Credit encourages the production, collection, and transportation of biomass for biofuel production. It helps offset the transportation costs for biomass producers and collectors for a variety of bioenergy feed stocks by paying a set rate per unit of material delivered to a qualified bioenergy facility. This report is intended to help evaluate the effects of the tax credit on the Oregon’s wood fuel market and Oregon’s economy more broadly.This working paper was completed in response to a request from the Oregon Department of Energy. We thank John Pine and Andrew Herstrom with the Oregon Department of Forestry, and Gail Krumenauer with the State of Oregon Employment Department for their support through this project

Suppression of axial growth by boron incorporation in GaAs nanowires grown by self-catalyzed molecular beam epitaxy

The addition of boron to GaAs nanowires grown by self-catalyzed molecular beam epitaxy was found to have a strong effect on the nanowire morphology, with axial growth greatly reduced as the nominal boron concentration was increased. Transmission electron microscopy measurements show that the Ga catalyst droplet was unintentionally consumed during growth. Concurrent radial growth, a rough surface morphology and tapering of nanowires grown under boron flux suggest that this droplet consumption is due to reduced Ga adatom diffusion on the nanowire sidewalls in the presence of boron. Modelling of the nanowire growth puts the diffusion length of Ga adatoms under boron flux at around 700-1000nm. Analyses of the nanowire surfaces show regions of high boron concentration, indicating the surfactant nature of boron in GaAs

Peculiar Velocities of Galaxy Clusters

We investigate the peculiar velocities predicted for galaxy clusters by theories in the cold dark matter family. A widely used hypothesis identifies rich clusters with high peaks of a suitably smoothed version of the linear density fluctuation field. Their peculiar velocities are then obtained by extrapolating the similarly smoothed linear peculiar velocities at the positions of these peaks. We test these ideas using large high resolution N-body simulations carried out within the Virgo supercomputing consortium. We find that at early times the barycentre of the material which ends up in a rich cluster is generally very close to a high peak of the initial density field. Furthermore the mean peculiar velocity of this material agrees well with the linear value at the peak. The late-time growth of peculiar velocities is, however, systematically underestimated by linear theory. At the time clusters are identified we find their rms peculiar velocity to be about 40% larger than predicted. Nonlinear effects are particularly important in superclusters. These systematics must be borne in mind when using cluster peculiar velocities to estimate the parameter combination $\sigma_8\Omega^{0.6}$.Comment: 8 pages, 4 figures; submitted to MNRA
