Boston, Massachusetts, 2-Dimensional Building Footprints with Height Data (from LIDAR data), 2002

This dataset consists of 2D footprints of the buildings in the metropolitan Boston area, based on tiles in the orthoimage index (orthophoto quad ID: 229890, 229894, 229898, 229902, 233886, 233890, 233894, 233898, 233902, 237890, 237894, 237898, 237902, 241890, 241894, 241898, 241902, 245898, 245902). This data set was collected using 3Di's Digital Airborne Topographic Imaging System II (DATIS II). Roof height and footprint elevation attributes (derived from 1-meter resolution LIDAR (LIght Detection And Ranging) data) are included as part of each building feature. This data can be combined with other datasets to create 3D representations of buildings and the surrounding environment.

Surveillance Studies and the Surveilled Subject

Surveillance studies has been somewhat inattentive to the perspective of the surveilled subject. It is the functioning of the surveillance apparatus, not the relatively inconsequential subject, which has tended to frame the focus of surveillance inquiries; leaving understandings of surveilled subjects’ experiences relatively limited. This research addresses this gap in the literature, exploring ways in which surveillance studies might understand the surveilled subject with greater consistency. Participants (N=47) shared their encounters with and perceptions of surveillance in a specific (Pearson International Airport) and general (everyday life) context through semi-structured interviews. The findings suggest that surveilled subjects’ encounters can be understood with some consistency – characterized by consistent criteria across subjects and contexts, and through a consistent theoretical framework across subjects in a specific context. However, consistency should not be confused with uniformity; encounters with surveillance must also be recognized for the extent to which they are nuanced and situated. For example, as this study also highlights, participants’ perceptions of encounters with surveillance at Pearson International Airport were differentially distributed in relation to identity characteristics (particularly minority status).

MRI Registration for Human Hip Kinematics

Measurement of joint kinematics can provide knowledge to help improve joint prosthesis design, as well as identify joint motion patterns that may lead to joint degeneration or injury. More investigation into how the hip translates in live human subjects during high amplitude motions is needed. This work presents a design of a non-invasive method using the registration between images from conventional Magnetic Resonance Imaging (MRI) and open MRI to calculate three dimensional hip joint kinematics. The method was tested on a single healthy subject in three different poses. MRI protocols for the conventional gantry, high-resolution MRI and the open gantry, lowresolution MRI were developed. The scan time for the low-resolution protocol was just under 6 minutes. High-resolution meshes and low resolution contours were derived from segmentation of the high-resolution and low-resolution images, respectively. Low-resolution contours described the poses as scanned, whereas the meshes described the bones’ geometries. The meshes and contours were registered to each other, and joint kinematics were calculated. The segmentation and registration were performed for both cortical and sub-cortical bone surfaces. A repeatability study was performed by comparing the kinematic results derived from three users’ segmentations of the sub-cortical bone surfaces from a low-resolution scan. The root mean squared error of all registrations was below 1.92mm. The maximum range between segmenters in translation magnitude was 0.95mm, and the maximum deviation from the average of all orientations was 1.27◦. This work demonstrated that this method for non-invasive measurement of hip kinematics is promising for measuring high-range-of-motion hip motions in vivo.

A Copernican turn in Banking Union urgently needed. CEPS Policy Brief No. 297, July 2013 [is another Brief with no. 297]

Despite broad agreement among central bankers, policy-makers and economists that creation of a ‘Banking Union’ is essential for the survival of the euro, progress in building this union has been painfully slow. This is largely due to the protracted fights over which government will be the payer of last resort when banks fail because of bad loans made in the past. Taking a cue from Copernicus, Thomas Mayer suggests in this new CEPS Policy Brief that the impasse may be broken by turning the whole process on its head. So, instead of trying to move from common bank supervision, over to bank resolution and then on to deposit insurance, he proposes reversing the process by starting with deposit insurance, moving from there to resolution and ending with supervision.

Reviewing the EU's market abuse rules. ECMI Policy Brief No. 19, 27 February 2012

Updated May 2012 and reposted: In 2011, an EU legislative package on market abuse was proposed, which comprises two sets of documents: 1) a draft Regulation that will largely replace the existing Market Abuse Directive (MAD) and the level 2 measures; and a new Directive dealing with criminal sanctions. Market abuse rules are needed to ensure market integrity and investor confidence, and to allow companies to raise capital and contribute to economic growth, thereby increasing employment. This ECMI Policy Brief argues that rules on market abuse should be technically well designed, proportionate and crystal clear, but also subject to more efficient and harmonised supervision than before. The paper focuses particularly on the draft Regulation. The use of a regulation is welcome, as (in integrated financial markets) abuses should be regulated in a harmonised manner by member states, which has not always been the case, as the 2007 report from the European Securities Markets Expert (ESME) Group extensively demonstrated. At the same time, this paper criticises some of the provisions contained in the draft Regulation, notably the new notion of inside information not to abuse (Art. 6(e)) and the unchanged definition of inside information for listed companies to disclose, and it proposes new definitions. The extension of disclosure obligations to issuers whose shares are traded on demand only on ‘listing’ multilateral trading facilities is also widely criticised. Other comments deal with the proposed rules on managers’ transactions, insiders’ lists and accepted market practices.
