Since the Oslo Accords were signed between Israel and the Palestinian Liberation Organization (PLO) in September 1993, the international community has supported civil policing programmes. It has done so as part of its development commitments to Palestinian state-building. Such programmes were, until the outbreak of the second Intifada in 2000, largely regarded as successful in terms of supporting the establishment of a Palestinian civil police (PCP). Such programmes were essentially Western imported models which loosely mixed community and public order policing approaches. With re-engagement in the Palestinian security sector (PSS) in the West Bank in 2007, the international community has once again sought to play a major role in PSS reform. This role includes supporting rehabilitation and retraining of the PCP as a principal institution of state-building. Such activities alongside the so-called transformation efforts within the wider realm of the PSS have re-established as their goal law and order. Within the transformation agenda, there are inherent demands with respect to Israel and the Palestinian National Authority's security and counterterrorism agendas. This analysis examines these activities, and accompanying political intent to contend that such approaches are undermining principles of democratic policing including civil police primacy (CPP). CPP reinforces police universality and means supporting rule of law by putting security under governmental control with proper mechanisms of accountability. This article argues that support to the security sector in the West Bank has increasingly only paid lip service or sought to subvert normative approaches to democratic policing.

Multi-bit trie is a popular approach performing the longest prefix matching for packet classification. However, it requires a long lookup time and inefficiently consumes memory space. This paper presents an in-depth study of different variations of multi-bit trie for IP address lookup. Our main aim is to study a method of data structure which reduces memory space. The proposed approach has been implemented using the label method in two approaches. Both methods present better results regarding lookup speed, update time and memory bit consumptions.

Suction is an important stress variable that is required for reliable predictions of the likely performance of unsaturated soils. The axis translation technique is the best established method of measuring or controlling suction; however, the success of this application is heavily dependent on the rating of the high air entry filter (HAF) and how it is incorporated into the testing system. This paper reports some basic experiments in which samples of unsaturated kaolin were brought to saturation in stages using 5 bar and 15 bar HAFs. The results have shown that the water equilibrium in unsaturated soils is greatly affected by the rating of filters. The findings also suggest that the flow through unsaturated soils is not necessarily governed by the one-dimensional consolidation theory that was developed for saturated soils, and this may be attributed to the bimodal pore size distribution of unsaturated soils.

The design of a high-performance IIR (infinite impulse response) digital filter is described. The chip architecture operates on 11-b parallel, two's complement input data with a 12-b parallel two's complement coefficient to produce a 14-b two's complement output. The chip is implemented in 1.5-µm, double-layer-metal CMOS technology, consumes 0.5 W, and can operate up to 15 Msample/s. The main component of the system is a fine-grained systolic array that internally is based on a signed binary number representation (SBNR). Issues addressed include testing, clock distribution, and circuitry for conversion between two's complement and SBNR.

The global financial crisis underscored the importance of regulation and supervision to a well functioning banking system that efficiently channels financial resources into investment. In this paper, we contribute to the ongoing policy debate by assessing whether compliance with international regulatory standards and protocols enhances bank operating efficiency. We focus specifically on the adoption of international capital standards and the Basel Core Principles for Effective Bank Supervision (BCP). The relationship between bank efficiency and regulatory compliance is investigated using the (Simar and Wilson 2007) double bootstrapping approach on an international sample of publicly listed banks. Our results indicate that overall BCP compliance, or indeed compliance with any of its individual chapters, has no association with bank efficiency.

This paper examines the role of the Anaesthetic Nuse Specialist(ANS) in the context of innovative cochlear implant surgery which restores hearing to those with long term deafness. The specific focus is patient centered care during the long surgery under local anaestha when the patient is awake.
It is crucial during this surgery that the patient remains still, relaxed and calm, the ANS has been particularly creative using communication cards and tablets to allow patients to write questions and the nurse to answer. The writers capture the unique moment when someone with long term hearing can hear, and the ensuing emotion from the patient and theatre team.

Past research has frequently attributed the incidence of bank failures to macroeconomic cycles and/or downturns in the regional economy. More recent analyses have suggested that the incidence and severity of bank failures can be linked to governance failures, which may be preventable through more stringent disclosure and auditing requirements. Using data on bank failures during the years 1991 to 1997, for the US, Canada, the UK and Germany, this study examines the relationship between institutional characteristics of national legal and auditing systems and the incidence of bank failures. In the second part of our analysis we then examined the relationship between the same institutional variables and the severity of bank failures.
The first part of our study notes a significant correlation between the law and order tradition (‘rule of law’) of a national legal system and the incidence of bank failures. Nations which were assigned high 'rule of law’ scores by country risk guides appear to have been less likely to experience bank failures. Another variable which appears to impact on bank failure rates is the ‘risk of contract repudiation’. Countries with a greater ‘risk of contract repudiation’ appear to be more likely to experience bank failures. We suggest that this may be due to a greater ex ante protection of stakeholders in countries where contract enforcement is more stringent.
The results of the second part of our study are less clear cut. However, there appears to be a significant correlation between the amount paid out by national deposit insurers (our proxy for the severity of bank failures) and the macroeconomic variable 'GDP change'. Here our findings follow the conventional wisdom; with greater amounts of deposit insurance funds being paid during economic downturns (i.e. low or negative GDP 'growth' correlates with high amounts of deposit insurance being paid out). A less pronounced relationship with the severity of bank failures can also be established for the institutional variables ' accounting standards' as well as 'risk of contract repudiation'. Countries with more stringent ‘accounting standards’ and a low ‘risk of contract repudiation’ appear to have been less prone to severe bank failures.

Murid gammaherpesvirus 4 (MuHV-4) is widely used as a small animal model for understanding gammaherpesvirus infections in man. However, there have been no epidemiological studies of the virus in wild populations of small mammals. As MuHV-4 both infects cells associated with the respiratory and immune systems and attempts to evade immune control via various molecular mechanisms, infection may reduce immunocompetence with potentially serious fitness consequences for individuals. Here we report a longitudinal study of antibody to MuHV-4 in a mixed assemblage of bank voles (Clethrionomys glareolus) and wood mice (Apodemus sylvaticus) in the UK. The study was conducted between April 2001 and March 2004. Seroprevalence was higher in wood mice than bank voles, supporting earlier work that suggested wood mice were the major host even though the virus was originally isolated from a bank vole. Analyses of both the probability of having antibodies and the probability of initial seroconversion indicated no clear seasonal pattern or relationship with host density. Instead, infection risk was most closely associated with individual characteristics, with heavier males having the highest risk. This may reflect individual variation in susceptibility, potentially related to variability in the ability to mount an effective immune response.

We describe seven polymorphic, dinucleotide microsatellite loci isolated from bank voles (Clethrionomys glareolus, Rodentia: Muridae) collected from the Wirral Peninsula, United Kingdom. Microsatellites were isolated as part of a long-term study on the wider effects of host-pathogen interactions of an endemic viral disease. These microsatellites showed between five and 13 alleles per locus in these populations. Observed and expected heterozygosities varied between 0.275 to 0.777 and 0.487 to 0.794, respectively. These markers will allow us to investigate the structure of this bank vole population. © 2005 Blackwell Publishing Ltd.

Bail-in is quickly becoming a predominant approach to banking resolution. The EU Bank Recovery Resolution Directive and the US Federal Deposit Insurance Corporation’s single point of entry strategy envisage creditors’ recapitalisations
to resolve a failing financial institution. However, this legislation focuses on the domestic aspects of bail-in, leaving the question of how it is applied
to a cross-border banking group open. Cross-border banking resolution has been historically subject to coordination failures, which have resulted in disorderly resolutions with dangerous systemic effects. The goal of this article is to assess whether bail-in is subject to the same coordination problems that affect other resolution tools, and to discuss the logic of international legal cooperation in bail-in policies. We demonstrate that, in spite of the evident benefit in terms of fiscal sustainability, bail-in suffers from complex coordination problems which, if not addressed, might lead to regulatory arbitrage and lengthy court battles, and, ultimately, may disrupt resolutions. We argue that only a binding legal regime can address those problems. In doing so, we discuss the recent Financial Stability
Board’s proposal on cross-border recognition of resolution action, and the role of international law in promoting cooperation in banking resolution.

In this paper, a recursive filter algorithm is developed to deal with the state estimation problem for power systems with quantized nonlinear measurements. The measurements from both the remote terminal units and the phasor measurement unit are subject to quantizations described by a logarithmic quantizer. Attention is focused on the design of a recursive filter such that, in the simultaneous presence of nonlinear measurements and quantization effects, an upper bound for the estimation error covariance is guaranteed and subsequently minimized. Instead of using the traditional approximation methods in nonlinear estimation that simply ignore the linearization errors, we treat both the linearization and quantization errors as norm-bounded uncertainties in the algorithm development so as to improve the performance of the estimator. For the power system with such kind of introduced uncertainties, a filter is designed in the framework of robust recursive estimation, and the developed filter algorithm is tested on the IEEE benchmark power system to demonstrate its effectiveness.
