Online Peer Assessment: A Student Reflection

This short essay is based on a task given to us in our induction week to university, and what was built upon throughout our first semester in the Research and Professional Development module. Finding out in the first few weeks of starting university that twenty of your peers who you barely know are going to be reading and analysing your work is quite a terrifying thought. However, as this essay will discuss, online peer assessment is a useful tool to help people learn and develop if it is utilised and structured in the correct way. The peer assessment that we undertook was split into three stages, the first being the actual writing of the essay, second was assessing each others work and third was our own reflection of the workshops, deciphering what we had learnt and how we can apply it to our own work.
Key Compression for Isogeny-Based Cryptosystems

We present a method for key compression in quantumresistant isogeny-based cryptosystems, which allows a reduction in and transmission costs of per-party public information by a factor of two, with no e ect on security. We achieve this reduction by associating a canonical choice of elliptic curve to each j-invariant, and representing elements on the curve as linear combinations with respect to a canonical choice of basis. This method of compressing public information can be applied to numerous isogeny-based protocols, such as key exchange, zero-knowledge identi cation, and public-key encryption. We performed personal computer and ARM implementations of the key exchange with compression and decompression in C and provided timing results, showing the computational cost of key compression and decompression at various security levels. Our results show that isogeny-based cryptosystems achieve by far the smallest possible key sizes among all existing families of post-quantum cryptosystems at practical security levels; e.g. 3073-bit public keys at the quantum 128-bit security level, comparable to (non-quantum) RSA key sizes.
Public Health Approaches to Palliative Care: The Role of the Hospice Social Worker Working with Children Experiencing Bereavement

In Western societies, death, dying and palliative care are surrounded by confusion and ignorance, with specialist palliative care only available to the lucky few ( Kellehear, 2007). A public health approach to palliative care has been recognised for the contribution it can make to meaningful end-of-life care. Such approaches have gained increased literature and policy focus and practice examples exist worldwide. In the UK, end-of-life care policy documents have highlighted the significance of a public health approach. They identify action to challenge stigma associated with death and dying to enable positive end-of-life care experiences. This paper discusses contemporary thinking around death and dying and how this relates to public health approaches to palliative care. It outlines the social work role in end-of-life care and discusses the significance of a public health approach drawing on practice experience as a hospice social worker involved in the facilitation of a children's bereavement service. It argues that social work has a significant role in the development of public health approaches to palliative care.
Factors that influence patient choice of contact lens or photorefractive keratectomy.

OBJECTIVE To explore characteristics of patients and factors that influence their decision in selecting photorefractive keratectomy (PRK) and contact lenses. METHODS A questionnaire was presented to 255 PRK and 240 contact lens patients, covering patient demographics, refraction, reasons for choosing PRK or contact lens, and advice from clinicians or friends/relatives. RESULTS Mean patient age was 37 years for PRK and 26 years for contact lens (P < .0001). The magnitude of the mean spherical equivalent refraction in the better eye was 4.14 D for PRK and 3.26 D for contact lens. Advertising influenced 36% (n = 92) of PRK compared to 17% (n = 41) of contact lens patients. In the PRK group, 52% (n = 133) opted for PRK based on cost; in the contact lens group the cost of PRK was thought to be high by 68% (n = 163). Eighty-four percent (n = 214) of the PRK group were contact lens wearers; of these, 32% (n = 68) were intolerant to contact lenses and 13% (n = 28) were intolerant to lens care solutions. Fifty-six percent (n = 134) of the contact lens group were concerned about the long-term effects of PRK and 49% (n = 118) were afraid to undergo a surgical procedure. CONCLUSIONS PRK patients were significantly older but had only marginally higher refractive error than contact lens patients. Many patients appeared to discontinue contact lens use due to tolerance problems.
Offshoring and the Polarization of the U.S. Labor Market

Using firm-level data on offshoring paired with occupation-level data on employment and wages, the author estimates the impact that offshoring has had on U.S. workers from 2002 to 2008. She finds that offshoring by U.S. firms has contributed to relative gains for the most high-skilled workers and relative losses for middle-skilled workers. An increase in offshoring in an industry is associated with an increase in the wage gap between workers at the 75th percentile and workers with median earnings in that industry, and with a decrease in the gap between workers earning the median wages and those at the 25th percentile. This pattern can be explained by the tasks performed by workers. Offshoring is associated with a decrease in wages for occupations that rely heavily on routine tasks and an increase in wages if the occupation is nonroutine and communication-task intensive. The results hold in both ordinary least squares (OLS) and instrumental variable specifications.
Capturing Situational Information with Smartphones and Mobile Sensing Methods 1

Smartphones are pervasive companions to many people as they go about their daily lives. In addition, they are equipped with a wide array of sensors making it possible to measure objective information about people and situations, many times, with great fidelity, over long periods of time, in a way that is both unobtrusive and ecologically valid. Therefore, we argue that smartphones and other forms of mobile sensing are ideally suited to measuring situations. In particular, we describe how sensing methods can be used to assess situational cues, characteristics and classes. Copyright © 2015 European Association of Personality Psychology
TwinCloud: Secure cloud sharing without explicit key management

In this paper, we propose TwinCloud as a client-side solution providing a secure system to users without compromising the usability of cloud sharing. TwinCloud brings a novel solution to the complex key exchange problem and provides a simple and practical approach to store and share files by hiding all the cryptographic and key-distribution operations from users. Serving as a gateway, TwinCloud stores the encryption keys and encrypted files in separate clouds which ease the secure sharing without a need for trust to either of the cloud service providers with the assumption that they do not collude with each other. TwinCloud is a lightweight application and available as open-source.
Speaker verification by inexperienced and experienced listeners vs. speaker verification system

This paper describes the participation of the LIA in the Human Assisted Speaker Recognition (HASR) task of the NIST-SRE 2010 evaluation campaign and its extension to a larger number of listeners. The human performance in such unfavorable conditions is analyzed in relation to the decision of a speaker recognition automatic system. Results of the perception test showed an important inter-trial variability (from 3% to 90% of correct answers for non-target trials) whereas there was no significant difference between the experienced and inexperienced listeners. Some complementarity between speaker verification system and human decisions was also found.
Fast temporal projection using accurate physics-based geometric reasoning

Temporal projection is the computational problem of predicting what will happen when a robot executes its plan. Temporal projection for everyday manipulation tasks such as table setting and cleaning is a challenging task. Symbolic projection methods developed in Artificial Intelligence are too abstract to reason about how to place objects such that they do not hinder future actions. Simulation-based projection is fine-grained enough but computationally too expensive as it is not able to abstract away from the execution of uninteresting actions (such as navigation). In this paper we propose a novel temporal projection mechanism that combines the strengths of both approaches: it is able to abstract away from the execution of continuous but uninteresting actions and provides the realism and fine grainedness needed to reason about critical situations.
From War to Security: Security Studies, the Wider Agenda and the Fate of the Study of War

This article critiques the wider agenda in security studies from the perspective of the idea of a war studies. It argues that security studies in any form has not adequately addressed the phenomenon of war and that IR more generally reduces war to an effect of the states system. An analysis of inquiry into the Second World War illuminates these points, while the Vietnam War is mobilised to show how the study of war can refigure our understanding of the international as a distinct social space. The conclusion suggests a new critical research agenda centred on politics, force, and war.
Exposure: Theory and Evidence about All the Ways it Matters

Abstract Much work on the public health communication component of social marketing focuses on message development. But there is good evidence that failure and success in public health communication is better predicted by variation in exposure to messages achieved than it is by variation in quality of messages. The inconsistent results about effects from some major projects (Stanford Heart Disease, Minnesota Heart Health, Pawtucket Heart Health, COMMIT) may reflect their lack of success in obtaining heavy exposure to their messages. Those results contrast with the successful results of a variety of other programs, particularly kitchen sink programs, which have been able to obtain higher levels of exposure and have some evidence of important effects.
The Applicant Attribution-Reaction Theory (AART): An Integrative Theory of Applicant Attributional Processing

This article proposes a new theory called the Applicant Attribution-Reaction Theory (AART) to better understand attributional processes in the formation of applicant reactions. The theory proposes that applicants' affective, behavioral, and cognitive reactions, such as fairness, test perceptions, test performance, and motivation, are fundamentally driven by an attributional process. A key implication of the theory is that perceptions such as fairness and test attitudes carry little explanatory power; instead they are consequences of attributional processing. We provide a brief review of dominant applicant reactions frameworks, review the social psychological literature on attributions, and present the theory. We then contrast the theory to existing conceptualizations, and finally describe its potential for better understanding several key topics in applicant reactions, including the justice judgment process, test performance, and racial subgroup differences. The theory has the potential to integrate many diverse perspectives on applicant reactions, and provides numerous directions for future research and practice.
Measuring Acculturation: Where We Are and Where We Need to Go

Acculturation measures intend to capture the psychological, behavioral, and attitudinal changes that occur when individuals and groups from different cultures come into continuous contact with each other. This article examines the most prominent theoretical models and assumptions that drive acculturation measures. Examples of Hispanic acculturation measures are used to illustrate how these theoretical foundations are applied in empirical measures. Particular emphasis is given to discussing the strengths and limitations of two bidimensional measures, the Bidimensional Acculturation Scale for Hispanics (BAS) and the Acculturation Rating Scale for Mexican Americans-Revised (ARSMA-II). Recommendations for improving these measures are presented. Moving beyond proxy measures, improving the operationalization of acculturation indicators, and incorporating theoretical models, as well as contextual variables, are the key recommendations presented for improving measures of acculturation.
Star shaped polymers : a model for the conformation and its concentration dependence

We propose a model giving the conformation of a star shaped polymer by taking into account the radial variation of the monomer concentration ϕ( r). For an isolated star when increasing r (at the centre of the star r = 0), the variation of ϕ (r) is first given by a constant value (r f1/2 ν-1 l); wh ere f is the number of branches, N the number of monomers in a branch and ν and l are the excluded volume and the length associated to a monomer. For all these cases, it is shown that the size of a branch is always larger than that of a linear polymer made of N monomers. Beyond the overlapping concentration the star conformation is obtained from two characteristic lengths essentially : χ(c ) a radius inside which the branches of the other stars do not penetrate, this radius defines a domain where the conformation of a star is similar to that of an isolated one. Beyond χ(c) the interpenetration of branches is characterized by a screening length ξ(c) very similar to that found for semi-dilute solutions of linear polymers. For all these regimes the variation of the size of a star is predicted as a function of N, f, v and c.
Body mass index of children from the United Kingdom diagnosed with pervasive developmental disorders

Abstract Background : The aim of the present study was to ascertain the Body Mass Index (BMI) (kg m–2) derived from parental reports of height (metres) and weight (kilograms) of a pilot sample of boys born and resident in the UK diagnosed with pervasive developmental disorders (PDD).
Miniaturization of branch-linecoupler with the use of inductors and capacitors

This paper describes the miniaturization process for the branch-line coupler operating in the microwave band. This device is widely used in various fields of radioelectronics due to its useful properties. However this device turns out to be too big at low frequencies, that is why it is necessary to reduce its sizes with the preservation of its characteristics at the level equal to the coupler of standard sizes. This study deals with the approach based on the replacement of quarter-wave sections with a line consisting of a folded inductor represented by the meander and a flat capacitor connected to it. This replacement allow us to obtain a compact device with technologically realizable sizes. With the use of the electrodynamic simulation program we created a model of the suggested coupler, and then produced a prototype based on the obtained results. Experimental results match the simulation results, but with a minor error. Thus, with the use of this approach we managed to reduce the sizes of the standard coupler by 70% with the 18% reduction of the working band.
3D Facial Normalization with Spin Images and Influence of Range Data Calculation over Face Verification

In this paper face verification techniques have been performed over 3D data acquired by a Laser Scanner. Advantages of 3D face models have been used to perform a normalization task over each face. First, an original method to detect local features points, based on Spin Images, has been developed. Once local features, as the nose tip or eyes corners, have been detected, a normalization process is carried out. After face normalization, different depth maps are calculated using several transform functions to equalize the images. The adequacy of each equalization to face verification has been measured to determine which one emphasizes most the feature discrimination. Face verification has been performed through a Principal Component Analysis and a Support Vector Machine. Final results show the importance of a careful 3D normalization and an optimal election of the depth map towards a improvement in the verification method.
Going Back to Civvy Street: A historical account of the impact of the Everest and Jennings wheelchair for Canadian World War II veterans with spinal cord injury

In February 1945, the Canadian government agreed to provide the Everest and Jennings folding, self-propelled wheelchair to all World War II veterans with spinal cord injury. These wheelchairs replaced wooden and wicker invalid wheelchairs that were usually assigned to hospital wards rather than to individuals. Veterans with spinal cord injury were among the first group of Canadians to use these wheelchairs to participate in community life. By 1947, Canadian veterans had demonstrated that it was possible to return to education, employment and leisure activities using a wheelchair. Drawing on oral history interviews and archival research, this paper provides an account of the introduction of folding, self-propelled wheelchairs into Canada following World War II. It discusses the impact of these wheelchairs on the life experiences of veterans, and outlines the strategies used by these early pioneers to live and work in communities that had neither expected nor planned for individuals using wheelchairs.
An Asymptotic Analysis of Fixed-Rate Lattice Vector Quantization

| We consider xed-rate k-dimensional lattice vector quantization of generalized Gaussian sources with decay parameter . We nd asymptotic expressions for the optimal scaling factor and resulting minimum distortion, as a function of codebook size N. It is shown that the optimal scaling factor a N increases as (lnN) 1== N ? 1=k and that the minimum distortion is D N = c (lnN) 2== N ? 2=k. This result indicates that the performance of optimal lattice quantizers diverges from that of asymp-totically optimal vector quantization, as N increases .
A review on leukotrienes and their receptors with reference to asthma

Abstract Objective and methods: Leukotrienes (LTs) including cysteinyl leukotrienes (CysLTs) and LTB4 are the most potent inflammatory lipid mediators and play a central role in the pathophysiology of asthma and other inflammatory diseases. These biological molecules mediate a plethora of contractile and inflammatory responses through specific interaction with distinct G protein-coupled receptors (GPCRs). The main objective of this review is to present an overview of the biological effects of CysLTs and their receptors, along with the current knowledge of mechanisms and role of LTs in the pathogenesis of asthma. Results: CysLTs including LTC4, LTD4 and LTE4 are ligands for CysLT1 and CysLT2 receptors, and LTB4 is the agonist for BLT1 and BLT2 receptors. The role of CysLT1 receptor is well established, and most of the pathophysiological effects of CysLTs in asthma are mediated by CysLT1 receptor. Several CysLT1 antagonists have been developed to date and are currently in clinical practice. Most common among them are classical CysLT1 receptor antagonists such as montelukast, zafirlukast, pranlukast, pobilukast, iralukast, cinalukast and MK571. The pharmacological role of CysLT2 receptor, however, is less defined and there is no specific antagonist available so far. The recent demonstration that mice lacking both known CysLT receptors exhibit full/augmented response to CysLT points to the existence of additional subtypes of CysLT receptors. LTB4, on the other hand, is another potent inflammatory leukotriene, which acts as a strong chemoattractant for neutrophils, but weaker for eosinophils. LTB4 is known to play an important role in the development of airway hyper-responsiveness in severe asthma. However there is no LTB4 antagonist available in clinic to date. Conclusion: This review gives a recent update on the LTs including their biosynthesis, biological effects and the role of anti-LTs in the treatment of asthma. It also discusses about the possible existence of additional subtypes of CysLT receptors.
High density emerging resistive memories: What are the limits?

With the saturation of the Flash memory technologies scaling under the 20nm nodes, new technology opportunities are explored by both industrial and academic research teams. Resistive switching memories are today seen as the most promising replacement candidate for both embedded (NOR) and stand-alone (NAND) flash memories. The native Back-End-of-Line (BEoL) integration enabled by the RRAM technologies opens the way for new 3D architectures such as crosspoint or Vertical-RRAM, and triggers the development of novel BEoL selection devices. These architectures bring new design challenges, for instance, sneaking currents through unselected bitcells (SneakPaths), voltage drop along deeply scaled (<50nm) metal lines (IRdrop) and peripheral circuitry overhead. In this paper, we introduce two physical IRdrop models for crosspoint and Vertical-RRAM architectures. We also introduce a peripheral circuitry model for crosspoint architecture. Using these models, we show that both periphery overhead and IRdrop limit the crosspoint architecture under 50nm of half pitch.
Metadata & Information Management Issues in XML-Based Mediation

The advancement in XML-based mediation has made a significant impact on the area of resource discovery. Search engines have now been provided with new ways to improve resource discovery and new tools to customise resulting content. In the early days of XML, this work was undertaken within the context of the European funded project GESTALT (Getting Educational System Talk Across Leading Edge Technologies). Building on this experience, new improvement came from the European funded project GUARDIANS (Gateway for User Access to Remote Distributed Information And Network Services). However, due to the lack of support for native XML databases and XML querying languages, search facilities were limited. This paper builds upon the achievements of both projects and proposes a solution for XML querying in XQuery.
A Three-Step Theory of Role Conflict Resolution

Summary Gross, Mason, and McEachern's theory of role conflict resolution is modified and a process theory is proposed which states that choice, solution, compromise, and avoidance are considered in this order. A reanalysis of data from five survey studies supports the following propositions of the revised theory: (a) in most situations only one of the conflicting role prescriptions is legitimate, has sanctions attached to it, or both (p<.001); (b) as a consequence of (a), choice is the most frequent reaction to role conflict (p<.001); (c) compromise and avoidance only play a part when the role prescriptions are both legitimate or illegitimate, and simultaneously associated or not associated with sanctions (p<.001).
