Next Generation CDN Services for Community Networks

Technological developments of the last few years have favoured the creation of distributed networking infrastructures (usually referred to as Community Networks) where the resources are made available to the members of a community of people. With emerging large-scale community infrastructures the opportunities for new commercial services and for innovative business models are becoming feasible. Since one of the most resource-demanding services today is access to user-generated content through the web, suitable content delivery services are needed in the context of Community Networks in orders to make an effective usage of shared resources. In this paper we describe two architectures we have designed to provide optimized delivery of multimedia web content (e.g. video but also other kinds of User Generated Content) within Community Networks. Both architectures work without any kind of cooperation from the original content providers but assume that a basic web caching service is provided within the network, either by commercial Service Providers or by the community members themselves. While the first architecture relies on a traditional centralized control entity, the second is designed according to the peer-to-peer paradigm, in order to provide better scalability, robustness to failures and self-configurability. Experimental results are also presented aimed at evaluating the performance gains for end-users from a localized distribution of content in scenarios in which community members are distributed in clusters sparse at different geographic locations.
The Effect of Locus of Control on the Relationship between Justice and Escalation of Commitment Level’s in Capital Budgeting

This study aims to discover and prove the effect from locus of control on the relationship between justice and the level for escalation of commitment. Hypothesis are: (1) a fair procedure would have a positive effect on the level for escalation of commitment; (2) a fair distribution would have a positive effect on the level for escalation of commitment; (3) a fair of procedures and distribution would have a positive effect on the level for escalation of commitment; (4) When a manager with an external locus of control were treated unfair of the level for escalation of commitment will be lower than when a person with internal locus of control were treated unfair. This research uses student subjects Accounting Profession Program Joint Program of Master in Accounting (31 people) and Masters in Development Economics (32 people) Faculty of Economics and Business Universitas Gadjah Mada. This research design experiments in the form of 2 x 2 between subject. Before conducting actual experiments, this study conducted a pilot test to test the instruments used. The hypothesis tested compiled using analysis of variance.

Then, with the locus of control is owned by each employee does not affect significantly the level for escalation of commitment.
F EEDBACK IN SECOND LANGUAGE ACQUISITION

One of the key questions concerning language acquisition is the question of how one can learn a new language while simultaneously being forced to communicate in that language. This is the situation which has probably always been the lot of the majority of children and adults acquiring a new language. It is the situation faced by the adults whose language acquisition we are examining in these volumes.
A game theoretic approach for securing AODV in emergency Mobile Ad Hoc Networks

In many extreme emergency cases such as forest fires or tube terrorist attacks, the rescuers have difficulty using traditional legacy networks due to destruction or collapse of the infrastructure in such events. We use the term emergency Mobile Ad hoc NETworks (eMANETs) in order to describe Next Generation Networks (NGNs) which are deployed in emergency cases. The security of these networks is critical. Especially secure routing is important given the fact that potential attackers aim to disrupt the appropriate operation of the routing protocol within an eMANET. In this paper we propose a game theoretic approach called AODV-GT (AODV-Game Theoretic) and we integrate this into the reactive Ad hoc On-demand Distance Vector (AODV) routing protocol to provide defense against blackhole attacks. AODV-GT is based on the concept of non-cooperative game theory. AODV-GT outperforms AODV in terms of malicious dropped packets when blackhole nodes exist within the eMANET. Our simulations were implemented using the network simulator ns-2.
Efficiency and Its Impact on the Performance of European Commercial Banks

The paper empirically analyzes the impact of the degree of efficiency on key performance fig-ures of publicly traded European banks in the period from 2005 to 2009. Efficiency is meas-ured by constructing non-parametric frontiers using the technique of data envelopment analysis on the cost, revenue, and profit sides. Decomposition of overall efficiency provides a detailed insight into effective risk and performance drivers in the banking industry. The results of our paper suggest that an increase in pure technical efficiency is related to more volatile assets, which is reflected in lower market values. Allocative and scale efficiency, however, boost capi-tal market performance.
Isolation and characterization of the sucrose 6-phosphate hydrolase gene from Streptococcus mutans

The Streptococcus mutans GS-5 gene, scrB, coding for sucrose 6-phosphate hydrolase activity has been cloned into Escherichia coli utilizing the bacteriophage replacement vector lambda L47.1. DNA sequences containing the gene were initially subcloned into the moderate-copy-number plasmid vector pLG339 to yield active subclones. However, due to the instability of the resultant chimeric plasmids, the gene was subsequently subcloned into the low-copy-number vector pOU61 to yield the stable hybrid plasmid pMH613. Both plasmids contain a 6.6-kilobase EcoRI fragment from strain GS-5 and express both hydrolase and sucrase activities. The relative position of the gene in the insert has been determined after Tn5 mutagenesis and deletion analysis. The cloned enzyme was purified to near homogeneity after gel filtration and anion-exchange chromatography, chromatofocusing, and preparative polyacrylamide gel electrophoresis. The purified enzyme displayed a molecular mass of 58 kilodaltons, which is significantly higher than the 48-kilodalton enzyme previously purified from S. mutans GS-5. These results suggest that processing of the hydrolase occurs in S. mutans.
Nagel's atlas

I Say that two people are in the justice relation if the allocation of goods across them is just or if it is unjust. Which pairs of people are in the justice relation? This is a question about justice’s scope. Nagel answers that two people are in this relation only if they belong to the same state; he shares it with the New Yorker who irons his shirt but not with the Brazilian who grows his coffee. (p. 141) Behind this question of scope there’s the deeper issue of justice’s ground. Which features of the situations of two people in the justice relation account for that relation by giving rise to considerations of justice? The question is deeper because nothing less than a theory of justice can answer it.
The linewidth enhancement factor of intersubband lasers

The linewidth enhancement (α-factor) of intersubband lasers was initially expected to be zero. However, nonzero values have been found in experimental investigations. This paper will give further details on how this controversy has been recently resolved by showing that counter rotating terms, usually ignored in simulations are the actual fundamental origin of nonzero α at peak gain even without inclusion of nonparabolicity and many-body effects, which are however needed to explain negative values. For laser without inversion conditions, α is found to be larger, but still at the same order of magnitude of conventional inverted medium lasers.
A cognitive sociolinguistic approach to metaphor and denominative variation: a case study of marine biology terms

This research applied corpus analysis techniques to a corpus of marine biology texts in Peninsular Spanish (PS) and Latin American Spanish (LAS). The results explain why these varieties of Spanish have different designations for the same sea organism. The focus of our research was thus on types of formal onomasiological variation (Geeraerts, Grondelaers, & Bakema, 1994) and its pervasiveness in Spanish scientific discourse. Also addressed was the incidence of metaphor in specialized concept formation and designation. Domain-specific and standard strategies were used for the semi-automatic retrieval of metaphorical terms. The resulting qualitative and quantitative account of terminological diversity reflected the pervasiveness of intralingual denominative variation in scientific language and also identified its causes.
Integrating baseband-over-fiber and six-port direct modulation for high-speed high-frequency wireless communications

A complete scheme by integrating baseband-over-fiber link and six-port direct modulation is proposed and experimentally demonstrated for uplinks in future high-speed high-frequency wireless communications systems. To handle high frequencies, GaAs MESFET RF switches are used to interface the baseband in-phase (I) and quadrature (Q) signals to six-port modulator. The baseband I and Q signals are transported over parallel single-mode fiber (SMF) links with the help of commercial low-cost digital optics. The proposed scheme features low cost, low complexity and low power consumption in particular for high-speed high-frequency wireless communications. 120 Mbaud quadrature phase shift keying (QPSK) signals at 19 GHz are generated and evaluated after transmission over up to 10 km single-mode fiber. The experimental results show insignificant degradation by introducing baseband-over-fiber links, especially for larger local oscillator power. Due to baseband-over-fiber transmission, the performance holds as the fiber length goes to 10 km from 2 km.
A biorobotic model of the suction-feeding system in largemouth bass: the roles of motor program speed and hyoid kinematics

ABSTRACT The vast majority of ray-finned fishes capture prey through suction feeding. The basis of this behavior is the generation of subambient pressure through rapid expansion of a highly kinetic skull. Over the last four decades, results from in vivo experiments have elucidated the general relationships between morphological parameters and subambient pressure generation. Until now, however, researchers have been unable to tease apart the discrete contributions of, and complex relationships among, the musculoskeletal elements that support buccal expansion. Fortunately, over the last decade, biorobotic models have gained a foothold in comparative research and show great promise in addressing long-standing questions in vertebrate biomechanics. In this paper, we present BassBot, a biorobotic model of the head of the largemouth bass (Micropterus salmoides). BassBot incorporates a 3D acrylic plastic armature of the neurocranium, maxillary apparatus, lower jaw, hyoid, suspensorium and opercular apparatus. Programming of linear motors permits precise reproduction of live kinematic behaviors including hyoid depression and rotation, premaxillary protrusion, and lateral expansion of the suspensoria. BassBot reproduced faithful kinematic and pressure dynamics relative to live bass. We show that motor program speed has a direct relationship to subambient pressure generation. Like vertebrate muscle, the linear motors that powered kinematics were able to produce larger magnitudes of force at slower velocities and, thus, were able to accelerate linkages more quickly and generate larger magnitudes of subambient pressure. In addition, we demonstrate that disrupting the kinematic behavior of the hyoid interferes with the anterior-to-posterior expansion gradient. This resulted in a significant reduction in subambient pressure generation and pressure impulse of 51% and 64%, respectively. These results reveal the promise biorobotic models have for isolating individual parameters and assessing their role in suction feeding. Summary: Experiments using a biorobotic model of the suction feeding system of ray-finned fishes reveal that motor program speed and kinematic timing of key musculoskeletal components affect subambient pressure generation.
Improved Model of Synchronous Generators Internal Faults Based on Circuit-Coupled FEM

A precise simulation of the internal faults of synchronous generators is crucial for the design of the main protection scheme; therefore, an accurate model is necessary. In this paper, based on the circuit-coupled finite element method (CCFEM), an improved model of a synchronous generator with internal faults is proposed, wherein the localized model of each stator coil is built as per its actual structure. Using this model, the internal fault occurring inside the coil can be accurately simulated, better approximating the location of the actual fault point; thus, the fault currents can be calculated more accurately. The accuracy of the improved model is verified by a dynamic simulation experiment. Moreover, the electromagnetic magnitudes, such as the air gap flux density, fault currents, field current, and all the damper currents are investigated in detail, under fault conditions, thereby revealing the fault characteristics more clearly and providing a basis for designing protection schemes.
Insights from the use of Gardner’s notions of Mindset: group work

A body of literature asserts that group work can be beneficial in enhancing learning and in developing specific skills among students. This research builds on the literature and on Gardner’s (2006a) five notions of mindsets: disciplined, synthesising, creation, ethical and respectful, as a descriptive framework to explore and understand the benefits and skills learnt or developed through group work. Gardner describes mindset as a way of thinking and acting. A qualitative research project was undertaken in a New Zealand university using in-depth interviews with post-experience students. The findings suggest that, though the post-experience students do possess skills that enabled them to integrate diverse perspectives, make new connections with shared knowledge and evaluate critically, they often lack specific mindsets that are critical in organisations that rely on group work to enhance their productivity.
Why Do We Like or Dislike Animals?

Animals are strong emotional triggers for us. The goal of this article is to identify causes and mechanisms that constitute liking or disliking animals. By combining deductions from emotion theory with empirical findings, six categories of causes can be distinguished: (1) an innate sensitivity for biological movement, (2) inherited quick learning programs to respond emotionally to some animals, (3) mental dispositions to respond emotionally to animals that result from conditioning, (4) an innate tendency to react emotionally to the emotional expressions of animals, (5) acquired knowledge about animals that influences the way we interpret an automatic bodily emotional reaction to an animal into a conscious experience, and (6) acquired knowledge about animals that can turn on emotional reactions to animals. Because emotions play a central role in the economy of the individual, the study of emotional responses may greatly enhance our understanding of the human dimensions of wildlife in general.
Documentation of Improved Outcomes for Intracranial Aneurysm Management Over a 15-Year Interval

Background and Purpose— Despite rapid advancements in intracranial aneurysm management, there is no evidence as of yet that this has translated into improvement in overall prognosis. Methods— We compared 2 periods of aneurysm management, 1998 to 2003 (n=1023 aneurysms) and 2007 to 2013 (n=1499 aneurysms), at a single, high-volume neurovascular center. Our outcome of interest was low or moderate disability (Glasgow Outcome Scale score of 4 or 5) at 6 months or more post treatment. Results— There were significant improvements in outcome for surgical, endovascular, and overall treatment of unruptured (adjusted odds ratio [OR], 2.33; P=0.0091; adjusted OR, 4.40; P=0.0271; and adjusted OR, 2.58; P=0.0008, respectively) and ruptured (adjusted OR, 3.18; P=0.0004; adjusted OR, 3.54; P=0.0001; and adjusted OR, 3.11; P<0.0001, respectively) aneurysms from the first to the second time period. In 2007 to 2013, the proportion of cases with low or moderate disability at 6 months post subarachnoid hemorrhage was 75.6% for surgical clipping and 76.6% for endovascular therapy. Conclusions— We report significantly improved outcomes over time for overall aneurysm management and for multiple patient subgroups, associated with increased usage of endovascular therapy.
Like Finding a Needle in a Haystack: Annotating the American National Corpus for Idiomatic Expressions

Our paper presents the details of a pilot study in which we tagged portions of the American National Corpus (ANC) for idioms composed of verb-noun constructions, prepositional phrases, and subordinate clauses. The three data sets we analyzed included 1,500-sentence samples from the spoken, the nonfiction, and the fiction portions of the ANC. Our paper provides the details of the tagset we developed, the motivation behind our choices, and the inter-annotator agreement measures we deemed appropriate for this task. In tagging the ANC for idiomatic expressions, our annotators achieved a high level of agreement (> .80) on the tags but a low level of agreement (< .00) on what constituted an idiom. These findings support the claim that identifying idiomatic and metaphorical expressions is a highly difficult and subjective task. In total, 135 idiom types and 154 idiom tokens were identified. Based on the total tokens found for each idiom class, we suggest that future research on idiom detection and idiom annotation include prepositional phrases as this class of idioms occurred frequently in the nonfiction and spoken samples of our corpus
Building applications using only demonstration

By combining the strengths of multiple interaction techniques and inferencing algorithms, Gamut can infer behaviors from examples that previously required a developer to annotate or otherwise modify code by hand. Gamut is a pro-gramming-by-demonstration (PBD) tool for building whole applications. It revises code automatically when new examples are demonstrated using a recursive procedure that efficiently scans for the differences between a new example and the original behavior. Differences that cannot be resolved by generating a suitable description are handled by another AI algorithm, decision tree learning, providing a significantly greater ability to infer complex relationships. Gamut’s interaction techniques facilitate demonstrating many examples quickly and allow the user to give the system hints that show relationships that would be too time consuming to discover by search alone. Altogether, the concepts combined in Gamut will allow nonprogrammers to build software they never could before.
PERSONAL IDENTIFICATION SYSTEMS FOR KEYSTROKE DYNAMICS WITH GENETIC ALGORITHM AND PARTICLE SWARM OPTIMIZATION

Techniques based on biometrics have been successfully applied to personal identification systems. Keystroke dynamics is a promising biometric technique to recognize an individual based on an analysis of his/her typing patterns. In the experiment we measure Mean and Standard deviation of feature values such as Latency, Duration and Digraph and compare the performance. Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) are used to implement feature subset selection and Back Propagation Neural Network (BPNN) is used for classification. Particle Swarm Optimization gives moderate performance than Genetic Algorithm with regard to feature reduction rate. Using digraph as the feature for feature subset selection is novel and show good classification performance.
Self-regulatory Efficacy as Potential Moderator on the Relationship Between Organisational Formal Controls, Perceived Group Norms and Workplace Deviance : A Proposed Framework

Several factors have been suggested to explain why employees engage in deviant behaviour at the workplace. To date, some of the factors that have been considered include perceived organisational politics perceived organizational justice, organizational trust, group cohesiveness and group identity, among others. Despite these studies, however, few studies have attempted to consider the influence of organisational formal controls and perceived group norms on workplace deviance. Even if any, they have reported conflicting findings. Therefore, a moderating variable is suggested. This paper proposes self-regulatory efficacy as potential moderator on the relationship between organisational formal controls, perceived group norms and workplace deviance.
Identification of Potential Herbal Inhibitor of Acetylcholinesterase Associated Alzheimer's Disorders Using Molecular Docking and Molecular Dynamics Simulation

Cholinesterase inhibitors (ChE-Is) are the standard for the therapy of AD associated disorders and are the only class of approved drugs by the Food and Drug Administration (FDA). Additionally, acetylcholinesterase (AChE) is the target for many Alzheimer's dementia drugs which block the function of AChE but have some side effects. Therefore, in this paper, an attempt was made to elucidate cholinesterase inhibition potential of secondary metabolite from Cannabis plant which has negligible or no side effect. Molecular docking of 500 herbal compounds, against AChE, was performed using Autodock 4.2 as per the standard protocols. Molecular dynamics simulations have also been carried out to check stability of binding complex in water for 1000 ps. Our molecular docking and simulation have predicted high binding affinity of secondary metabolite (C28H34N2O6) to AChE. Further, molecular dynamics simulations for 1000 ps suggest that ligand interaction with the residues Asp72, Tyr70-121-334, and Phe288 of AChE, all of which fall under active site/subsite or binding pocket, might be critical for the inhibitory activity of AChE. This approach might be helpful to understand the selectivity of the given drug molecule in the treatment of Alzheimer's disease. The study provides evidence for consideration of C28H34N2O6 as a valuable small ligand molecule in treatment and prevention of AD associated disorders and further in vitro and in vivo investigations may prove its therapeutic potential.
Translation validation for a verified OS kernel

We extend the existing formal verification of the seL4 operating system microkernel from 9500 lines of C source code to the binary level. We handle all functions that were part of the previous verification. Like the original verification, we currently omit the assembly routines and volatile accesses used to control system hardware. More generally, we present an approach for proving refinement between the formal semantics of a program on the C source level and its formal semantics on the binary level, thus checking the validity of compilation, including some optimisations, and linking, and extending static properties proved of the source code to the executable. We make use of recent improvements in SMT solvers to almost fully automate this process. We handle binaries generated by unmodified gcc 4.5. 1 at optimisation level 1, and can handle most of seL4 even at optimisation level 2.
