The best-kept secret(s) of evidence based policing
This paper draws on the work of the Evidence and Insight Team, a dedicated research function based within the Metropolitan Police Service for over a decade. The aim of the paper is to make readers aware of the obliquely hidden data goldmine that exists within UK policing. Such data captures the decisions police make routinely, the kinds of situations police encounter and with whom. This rich data seam goes beyond crime – and should be used more outside of policing. The authors argue that interested academics need a better roadmap of the data in order to stimulate basic knowledge and usage. Three case studies are presented that illustrate the scope and challenges of working with such data

Violence is as American as Cherry Pie: Mass Incarceration and Juvenile Violence
The purpose of this chapter is to offer “food for thought” regarding an under researched area of juvenile violence causation: the possible connection between steadily increasing incarceration rates and steadily increasing incidents of school violence. Unfortunately, the negative, and sometimes violent, traits individuals develop while incarcerated are often brought out into their lives in society and personal lives, which often involve the raising of children. Research has documented the impacts that being incarcerated can have upon an individual. There is growing research supporting that these newly developed traits and behaviors can easily be imbedded in the children in which they have contact with upon release. The authors argue that we should not be surprised about the increases in juvenile violence given the constant flow of individuals in and out of American prisons. This is not to say that everyone who has served time will follow this path, but this is one area where actions and patterns of behavior which have been developed in one social environment can saturate another
The Impact of Mass Incarceration and Social Issues of Institutionalization on School Violence in Youths
In this chapter the authors examine the impact that mass incarceration has had upon children in the United States over the last several decades. Inherent in this examination is to discuss the impact of institutionalization on the propensity of committing violent acts by children. The authors also discuss the impact of these American phenomena on many aspects of juvenile delinquency and violence
High-resolution wide-band Fast Fourier Transform spectrometers
We describe the performance of our latest generations of sensitive wide-band
high-resolution digital Fast Fourier Transform Spectrometer (FFTS). Their
design, optimized for a wide range of radio astronomical applications, is
presented. Developed for operation with the GREAT far infrared heterodyne
spectrometer on-board SOFIA, the eXtended bandwidth FFTS (XFFTS) offers a high
instantaneous bandwidth of 2.5 GHz with 88.5 kHz spectral resolution and has
been in routine operation during SOFIA's Basic Science since July 2011. We
discuss the advanced field programmable gate array (FPGA) signal processing
pipeline, with an optimized multi-tap polyphase filter bank algorithm that
provides a nearly loss-less time-to-frequency data conversion with
significantly reduced frequency scallop and fast sidelobe fall-off. Our digital
spectrometers have been proven to be extremely reliable and robust, even under
the harsh environmental conditions of an airborne observatory, with
Allan-variance stability times of several 1000 seconds. An enhancement of the
present 2.5 GHz XFFTS will duplicate the number of spectral channels (64k),
offering spectroscopy with even better resolution during Cycle 1 observations.Comment: Accepted for publication in A&A (SOFIA/GREAT special issue
