Community Perceptions of Police Capacity and Police Legitimacy in Seattle: Are They Connected?
No full textPolice legitimacy is of ongoing concern for police agencies in their interactions with the public. Police legitimacy is impacted by a range of factors. After the murder of George Floyd and the subsequent protests calling for systemic changes in policing, police legitimacy ratings declined in the United States. In the city of Seattle, police legitimacy ratings declined dramatically coinciding with an historical decrease in police staffing leading to a staffing crisis. The current study aims to investigate how community perceptions of police capacity in Seattle impact community perceptions of police legitimacy at citywide, precinct and neighborhood levels. Quantitative and qualitative data drawn from the 2024 Seattle Public Safety Survey. Results explore the differences in the citywide, precinct and neighborhood level. The data revealed that police capacity and police legitimacy are correlated with specific findings suggesting that the correlation is stronger in some precinct and neighborhoods t. Implications for police-community engagement in Seattle and other cities with attention to the relationship between police capacity and police legitimacy will be discussed
Xor-Trees for Efficient Anonymous Multicast and Reception
No full textIn this work we examine the problem of efficient anonymous broadcast and reception in general communication networks. We show an algorithm which achieves anonymous communication with O(1) amortized communication complexity on each link and low computational complexity. In contrast, all previous solutions require polynomial (in the size of the network and security parameter) amortized communication complexity.

Shaping Forces: Review of two Bridge Design Methodologies towards Architectural and Structural Symbiosis
No full textThis paper investigates the symbiotic relationship between the architectural appearance of a bridge and the structural design. The research is done by reviewing and comparing the design methodology employed by the first author in the conceptualization of two of his bridges; an early work from 1997 and a recent work from 2017. The review of the early work describes a design methodology that could be described as intuitive design, whereas the later work is the result of computational from-finding and optimization. Parallels are drawn and the historical development of the toolbox of the architect and the engineer is described. The paper analysis the way the two designs were achieved by looking from the perspective of the architect and that of the engineer, two disciplines that nowadays closely work together on the design of a bridge. The paper concludes by identifying the key design considerations to achieve a beautiful yet structurally sound bridge. The question whether beauty can be the sole result of a rational design process towards the most efficient form according to the laws of mechanics, is addressed. This paper demonstrate the belief that when it comes to the design of a bridge, architecture and structure, form and force, are involved in an interdependable and symbiotic relationship.OLD Structural DesignStructural Design & Mechanic
A bio-based fibre-reinforced plastic pedestrian bridge for Schiphol
No full textThe present paper investigates Bio-based fibre-reinforced plastics, used as a load-bearing element of a bridge. We aim to increase the renewable content and decreasing the embodied energy of FRP. To achieve that, the consisting raw materials of these plastics which are based on non-renewable resources, are substituted by alternative less energy intensive materials produced from biological renewable resources. The research focuses on the potentials of natural fibres for a successful substitution of artificial fibres used as reinforcement in load-bearing polymer composites, while bio-based resins and natural core materials are analysed as well. The result of the research is applied on a real case scenario of a lightweight structure, a pedestrian bridge in Schiphol Logistics Park, a logistics zone under development adjacent to Amsterdam’s International Airport.Architectural Engineering +TechnologyArchitecture and The Built Environmen
Software Protection and Simulation on Oblivious RAMs
No full textRafail Ostrovsky z Software protection is one of the most important issues concerning computer practice. There exist many heuristics and ad-hoc methods for protection, but the problem as a whole has not received the theoretical treatment it deserves. In this paper we provide theoretical treatment of software protection. We reduce the problem of software protection to the problem of e cient simulation on oblivious RAM. A machine is oblivious if the sequence in which it accesses memory locations is equivalent for any two inputs with the same running time. For example, an oblivious Turing Machine is one for which the movement of the heads on the tapes is identical for each computation. (Thus, the movement is independent of the actual input.) What is the slowdown in the running time of a machine, if it is required tobe oblivious? In 1979 Pippenger and Fischer showed how a two-tape oblivious Turing Machine can simulate, on-line, a one-tape Turing Machine, with a logarithmic slowdown in the running time. We show an analogous result for the random-access machine (RAM) model of computation. In particular, we show how to do an on-line simulation of an arbitrary RAM by a probabilistic oblivious RAM with a poly-logarithmic slowdown in the running time. On the other hand, we show that a logarithmic slowdown is a lower bound. This paper uni es and extends abstracts of [G-87] and [Ost-90] and is a re nement of the second author Ph.D
Bio-Based Composite Footbridge: Design, Production and In Situ Monitoring
No full textThis paper deals with the design, production and monitoring of a bio-composite footbridge with a span of 14 m across the river Dommel in the city of Eindhoven, the Netherlands. The specific bio-composite material that was used for this research is a Natural Fibre Reinforced Bio-Polymer (NFRBP). The goal of the research is to prove that NFRBP can be applied as a load-bearing structure in an outdoor environment. For this purpose, a multidisciplinary team of academic researchers from two universities and from the Centre of Expertise Biobased Economy, together with a manufacturer from the NFRBP industry, have developed a feasible design that could be produced in a short period of time and within a limited budget. The footbridge was designed, built and installed within less than one year. In the two years after the installation of the footbridge, the structural behaviour of the bridge was monitored by means of optical fibre glass strands, integrated within the structure, with the purpose of measuring deformations and change in elasticity that occur over time.Structural Design & MechanicsOLD Structural Desig

Human papillomavirus type 18 infection in a female renal allograft recipient: a case report
No full textPublisher Copyright: © 2016 The Author(s).Background: Human papillomavirus type 18 is the second most common cause of cervical cancer and is found in 7 to 20 % of cases of cervical cancer. The oncogenic potential of high-risk human papillomavirus is associated with expression of early proteins E6 and E7. Due to long-term immunosuppressive therapy, renal transplant recipients have a higher risk of developing persistent human papillomavirus infection. Case presentation: A 29-year-old white woman from Latvia with chronic focal segmental glomerulosclerosis received renal allograft transplantation and was prescribed immunosuppressive therapy with cyclosporine, prednisolone, and mycophenolate mofetil. Two weeks after renal transplantation, her cervical swab was positive for human papillomavirus consensus sequences. After 6 months, quantitative polymerase chain reaction showed a high viral load of 3,630,789 copies/105 cells of high-risk human papillomavirus type 18 and expression of E6 and E7 oncogenes in her cervical swab and urine sample. One year after renal transplantation, the viral load in her cervical swab increased significantly to 7,413,102 copies/105 cells. Messenger ribonucleic acid of human papillomavirus type 18 E6 and E7 oncogenes were also detected. Shortly after this, she had an unsuccessful pregnancy which resulted in a spontaneous abortion at 6/7 weeks. Two months after the abortion her viral load sharply decreased to 39 copies/105 cells. Oncogenes E6 and E7 messenger ribonucleic acid expression was not observed in this period. Conclusions: This case report represents data which show that immunosuppressive therapy may increase the risk of developing persistent high-risk human papillomavirus infection with expression of E6 and E7 oncogenes in renal transplant recipients. However, even during this therapy the immune status of a recipient can improve and contribute to human papillomavirus viral load reduction. Spontaneous abortion can be considered a possible contributory factor in human papillomavirus clearance.Peer reviewe
