The mediating effect of trust on the dimensionality of organisational justice and organisational citizenship behaviour amongst teachers in Malaysia

Abstract The swelling discourses on organisational citizenship behaviour (OCB) have diffused into areas of management and organisational research. The existing literature encapsulates that trust will mediate the relationship between the three dimensions of organisational justice: procedural justice, distributive justice and interactional justice and OCB. Based on the literature discussions, several hypotheses were proposed and conceptual framework was formulated. A total of 411 teachers had responded and participated in the survey. The collected data were analysed using Smart Partial Least Square software. Vigorous two-stage analytical procedure was adopted. The statistical results indicated that trust significantly mediates the relationship between organisational justice and OCB as well as the dimensions of organisational justice and OCB with various degrees of mediating effects. These findings have provided new insights in the organisational behaviour discipline and shed light on trust’s mediation in the relationship of organisational justice and OCB.
ALMOST ISOMETRIC EMBEDDINGS OF METRIC SPACES

We investigate a relations of almost isometric embedding and almost isometry between metric spaces and prove that with respect to these relations: (1) There is a countable universal metric space. (2) There may exist fewer than continuum separable metric spaces on @1 so that every separable metric space is almost isometrically embedded into one of them when the continuum hypothesis fails. (3) There is no collection of fewer than continuum metric spaces of cardinality @2 so that every ultra-metric space of cardinality @2 is almost isometrically embedded into one of them if @2 < 2 @0. We also prove that various spaces X satisfy that if a space X is almost isometric to X than Y is isometric to X.
White Noise Rejection in a Deterministic Setting

This paper provides a framework for analyzing white noise disturbances in linear systems. Rather than the usual stochastic approach, noise signals are described as elements in sets and the disturbance rejection properties of the system are considered in a worst case setting. The description is based on constraints in signal space, directly verifiable on experimental data. These constraints can be given a representation compatible with standard robust control, allowing the formulation of white noise rejection problems in the presence of other sources of uncertainty. It is also shown how the framework can capture as a special case the usual stochastic approach, with equivalent results.

Two-channel FIR filter banks based on the frequency-response masking approach

This paper introduces two-channel FIR filter banks synthesized using the frequency-response masking approach. The proposed filter banks have a lower computational complexity compared with conventional filter banks, especially when the individual filters have narrow transition bands. One price to pay is a somewhat increased overall delay. A design example is included illustrating the efficiency of the proposed filter banks.
Extending Conceptualization and Measurement of Narrative Engagement After-the-Fact: Parasocial Relationship and Retrospective Imaginative Involvement

ABSTRACT Engagement with narratives and identification with narrative characters is usually conceptualized as occurring during the narrative experience itself. However, much involvement with a story world and narrative characters may occur retrospectively and imaginatively. The present study, using a cross-sectional survey quota-sampled to represent U.S. demographic norms, provides conceptualization and measurement of parasocial relationships (PSR) that is clearly retrospective and conceptually distinct from parasocial interaction (PSI). Moreover, we distinguish PSR from another concept introduced and operationalized here, retrospective imaginative involvement (RII), and provide evidence for validity of these measures. We compare them to the related concepts of transportability and boundary expansion, and assess fit using measurement models and confirmatory factor analysis, refining measurement on half the data set and confirming fit on the other half. We demonstrate predictive validity with respect to a measure of self-reported effects of narratives on beliefs and behavior, controlling for these various related measures, and also validate short versions of these measures for greater ease of research use
War and Postwar Violence

Wars are related to subsequent violence in complex and at times contradictory ways. The relationships between war and postwar violence, recognized throughout history, have attracted the attention and concern of researchers, state officials, and policy makers and the broader public. Methodological challenges, however, limit the potential for isolating the precise circumstances under which war and postwar violence are causally related. The weight of the evidence indicates that war is often followed by increases in violence, but there are important exceptions to this pattern. Potential theoretical explanations for this relationship abound. The harmful effects of wars on the minds and bodies of those participating in them are less influential on postwar violence than are the damages wars do to postwar societies’ social and economic institutions, political legitimacy, and group relations. Preventing or reducing elevated rates of violence after wars is rarely a priority during peace negotiations. As a consequence, policies instituted as part of the peace-building process often fuel violent crime.
Nucleosynthesis-relevant conditions in neutrino-driven supernova outflows. I. Spherically symmetric

We investigate the behavior and consequences of the reverse shock that terminates the supersonic expansion of the baryonic wind which is driven by neutrino heating off the surface of (non-magnetized) new-born neutron stars in supernova cores. To this end we perform long-time hydrodynamic simulations in spherical symmetry. In agreement with previous relativistic wind studies, we find that the neutrino-driven outflow accelerates to supersonic velocities and in case of a compact, ~1.4$\,M_\odot$ (gravitational mass) neutron star with a radius of about 10 km, the wind reaches entropies of about 100$\,k_{\mathrm B}$ per nucleon. The wind, however, is strongly influenced by the environment of the supernova core. It is decelerated and shock-heated abruptly by a termination shock that forms when the supersonic outflow collides with the slower preceding supernova ejecta. The radial position of this reverse shock varies with time and depends on the strength of the neutrino wind and the explosion conditions in progenitor stars with different masses and structure. Its basic properties and behavior can be understood by simple analytic considerations. We demonstrate that the entropy of the matter going through the reverse shock can increase to a multiple of the asymptotic wind value. Seconds after the onset of the explosion it therefore can exceed 400$\,k_{\mathrm B}$ per nucleon in low-mass progenitors around 10$\,M_\odot$, where the supernova shock and the reverse shock propagate outward quickly. The temperature of the shocked wind has typically dropped to about or less than 10 9 K, and density and temperature in the shock-decelerated matter continue to decrease only very slowly. For more massive progenitors with bigger and denser metal cores, the explosion expands more slowly so that the termination shock stays at smaller radii and affects the wind at higher temperatures and densities. In this case the termination shock might play a non-negligible, strongly time- and progenitor-dependent role in discussing supernova nucleosynthesis.
The Incidence of Cerebral Venous Thrombosis: A Cross-Sectional Study

Background and Purpose— The purpose of this study was to determine the incidence of adult cerebral venous thrombosis. Methods— A retrospective cross-sectional study was conducted among all 19 hospitals located in 2 Dutch provinces serving 3.1 million people. Adult cerebral venous thrombosis cases diagnosed between January 1, 2008, and December 31, 2010, were identified using the Dutch financial coding system for hospital care and the International Classification of Diseases, 9th Revision. Medical records of potential patients were hand searched to identify cerebral venous thrombosis cases. The Dutch National Bureau for Statistics provided population figures of the 2 provinces during 2008 to 2010. Results— Among 9270 potential cases, we identified 147 patients diagnosed with cerebral venous thrombosis. Of these, 53 patients did not meet the inclusion criteria; therefore, 94 patients were included in the analysis. The overall incidence was 1.32 per 100 000 person-years (95% CI, 1.06–1.61). Among women between the ages of 31 and 50 years, the incidence was 2.78 (95% CI, 1.98–3.82). Conclusions— The incidence of cerebral venous thrombosis among adults is probably higher than previously believed.
Potential Uses of Probiotics in Clinical Practice

SUMMARY Probiotics are defined as live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. There is now mounting evidence that selected probiotic strains can provide health benefits to their human hosts. Numerous clinical trials show that certain strains can improve the outcome of intestinal infections by reducing the duration of diarrhea. Further investigations have shown benefits in reducing the recurrence of urogenital infections in women, while promising studies in cancer and allergies require research into the mechanisms of activity for particular strains and better-designed trials. At present, only a small percentage of physicians either know of probiotics or understand their potential applicability to patient care. Thus, probiotics are not yet part of the clinical arsenal for prevention and treatment of disease or maintenance of health. The establishment of accepted standards and guidelines, proposed by the Food and Agriculture Organization of the United Nations and the World Health Organization, represents a key step in ensuring that reliable products with suitable, informative health claims become available. Based upon the evidence to date, future advances with single- and multiple-strain therapies are on the horizon for the management of a number of debilitating and even fatal conditions.
Daily oceanographic analyses by the Mediterranean basin scale assimilation system

This study presents the upgrade of the Optimal Interpolation scheme used in the basin scale assimilation scheme of the Mediterranean Forecasting System . The modifications include a daily analysis cycle, the assimilation of ARGO float profiles, the implementation of the geostrophic balance in the background error covariance matrix and the initialisation of the analyses. A series of numerical experiments showed that each modification had a positive impact on the accuracy of the analyses: The daily cycle improved the representation of the processes with a relatively high temporal variability, the assimilation of ARGO floats profiles significantly improved the salinity analyses quality, the geostrophically balanced background error covariances improved the accuracy of the surface elevation analyses, and the initialisation removed the barotropic adjustment in the forecast first time steps starting from the analysis.
0 Se p 19 96 Different D-brane Interactions

We use rotation of one D-brane with respect to the other to reveal the hidden structure of D-branes in type-II theories. This is done by calculation of the interaction amplitude for two different parallel and angled branes. The analysis of strings with different boundary conditions at the ends is also given. The stable configuration for two similar branes occurs when they are anti-parallel. For branes of different dimensions stability is attained for either parallel or anti-parallel configurations and when dimensions differ by four the amplitude vanishes at the stable point. The results serve as more evidence that D-branes are stringy descriptions of non-perturbative extended solutions of SUGRA theories, as low energy approximation of superstrings.
Silicon nanomembrane based photonic crystal waveguide array for wavelength-tunable true-time-delay lines

We demonstrate a four-channel on-chip true-time-delay module based on a photonic crystal waveguide array. Using the photonic crystal taper to minimize the coupling loss, the delay lines with 1–3 mm long photonic crystal waveguides can operate up to a group index ng ∼ 23 without significant loss. The large group velocity dispersion enables continuous and wavelength-tunable time delays. Measurements show a highly linear phase-frequency relation, highest time delay up to 216.7 ps, and large tuning ranges of 58.28 ps, 115.74 ps, and 194.16 ps for 1–3 mm delay lines. The chip-scale true-time-delay module occupies only 0.18 mm2 area and can provide ±44.38° steering for an X-band phased-array-antenna.
Reproducible Scientific Computing Environment with Overlay Cloud Architecture

Science computing platforms are changing from traditional on-premises computing platforms to clouds. The style of research publications is also changing with the movement of open science. For example, it is common that researchers in the bioscience research community publish their research papers with the associated research data on the Internet. Furthermore, demands for reproducibility of computational experiments are increasing. A conventional method, or sharing source codes of application programs, is not enough to guarantee the reproducibility of computational experiments. In this paper, we propose overlay cloud architecture for building virtual clouds on cloud platforms. In the proposed architecture, the middleware, Virtual Cloud Provider (VCP), automatically configures computing environments (application programs, operating systems, libraries and binaries) that is required to reproduce computing results by using the Linux container technology. VCP also deploys containers of computing environments on clouds and configures overlay network connecting the deployed containers. A case study which considers DNA sequencing software shows how the VCP can be deployed, and used to reproduce results.
Dynamic Buffer Overflow Detection

The capabilities of seven dynamic buffer overflow detection tools (Chaperon, Valgrind, CCured, CRED, Insure++, ProPolice and TinyCC) are evaluated in this paper. These tools employ different approaches to runtime buffer overflow detection and range from commercial products to opensource gcc-enhancements. A comprehensive testsuite was developed consisting of specifically-designed test cases and model programs containing real-world vulnerabilities. Insure++, CCured and CRED provide the highest buffer overflow detection rates, but only CRED provides an open-source, extensible and scalable solution to detecting buffer overflows. Other tools did not detect off-by-one errors, did not scale to large programs, or performed poorly on complex programs.
How Your Phone Camera Can Be Used to Stealthily Spy on You: Transplantation Attacks against Android Camera Service

Based on the observations that spy-on-user attacks by calling Android APIs will be detected out by Android API auditing, we studied the possibility of a "transplantation attack", through which a malicious app can take privacy-harming pictures to spy on users without the Android API auditing being aware of it. Usually, to take a picture, apps need to call APIs of Android Camera Service which runs in mediaserver process. Transplantation attack is to transplant the picture taking code from mediaserver process to a malicious app process, and the malicious app can call this code to take a picture in its own address space without any IPC. As a result, the API auditing can be evaded. Our experiments confirm that transplantation attack indeed exists. Also, the transplantation attack makes the spy-on-user attack much more stealthy. The evaluation result shows that nearly a half of 69 smartphones (manufactured by 8 vendors) tested let the transplantation attack discovered by us succeed. Moreover, the attack can evade 7 Antivirus detectors, and Android Device Administration which is a set of APIs that can be used to carry out mobile device management in enterprise environments. The transplantation attack inspires us to uncover a subtle design/implementation deficiency of the Android security.
Fusion of submanifold and local texture features for palmprint authentication

In this paper, a palmprint based authentication system is proposed. The proposed system makes use of locality sensitive discriminant analysis and directional local extrema patterns. A locality sensitive discriminant analysis has the capability to project the palmprints into a new space, where the palmprints belonging to same class become closer, whereas those of different classes move far apart. Locality sensitive discriminant analysis gathers the discriminating information based on the local texture of the data and available ground truth values. A directional local extrema pattern extracts the directional edge information based on local extrema in 0°, 45°, 90°, and 135° directions in an image. A palmprint contains several lines in various directions. A directional local extrema pattern may prove beneficial to extract edge information from palmprints. The two kinds of features are fused at score level for authentication purpose. The PolyU pamprint dataset has been used for evaluation, and the results are found promising. To establish the improvements in palmprint recognition, the results of proposed system has been compared with several well established state of the art algorithms.

The students reported the Perceived ease of use and usefulness of the MSN robot for learning. The finding was that the MSN robot would be beneficial to and acceptable for learning community identification when applied to learning and teaching environments.
Lumino: tangible blocks for tabletop computers based on glass fiber bundles

Tabletop computers based on diffuse illumination can track fiducial markers placed on the table's surface. In this paper, we demonstrate how to do the same with objects arranged in a three-dimensional structure without modifying the table. We present lumino, a system of building blocks. In addition to a marker, each block contains a glass fiber bundle. The bundle optically guides the light reflected off markers in the higher levels down to the table surface, where the table's built-in camera reads it. While guiding marker images down, the bundle optically scales and rearranges them. It thereby fits the images of an entire vertical arrangement of markers into the horizontal space usually occupied by a single 2D marker. We present six classes of blocks and matching marker designs, each of which is optimized for different requirements. We show three demo applications. One of them is a construction kit that logs and critiques constructions. The presented blocks are unpowered and maintenance-free, keeping larger numbers of blocks manageable.
Performance Analysis of SFBC-OFDM System with Frequency Domain Equalization

- In modern wireless communication systems, Multiple Input Multiple Output (MIMO)-Orthogonal Frequency Division Multiplexing (OFDM) techniques have become popular. This system has potential to meet high data rate requirements and high performance over various challenging channels that may be time selective and frequency selective. MIMO-OFDM system exploits the space and frequency diversity simultaneously to improve the performance of system. The popular approach to combine the space time codes and OFDM system is SFBC-OFDM. In this paper, Space-Frequency block coding for MIMO-OFDM along with different equalizers is investigated. Bit Error Rate (BER) performance analysis is presented using different equalizers and then optimum equalization method is suggested.
Memristor-based cell design and digital logical operations implementation

Memristor-based cell is proposed in this paper. Digital logical operations in the proposed memrsitor cell can be performed with a voltage-controlled current (VCC) source input or a current-controlled voltage (CCV) source input. The important application of the proposed memristor cell is to build memristor-based sersors, memristor cellular automaton, and memristive cellular neural networks.
Introducing Restoration of Selectivity in Hearing Instrument Design Through Phoneme Spotting

Speech-model-based phoneme enhancement or replacement can be used to compensate losses of auditory selectivity that typically occur in people suffering from sensory hearing deficits. A dedicated phonetic spotter cam serve as control unit for selectivity-restoring speech processing; it offers effective control of phonemespecific enhancement and replacement. The future implementation in wearable lowpower DSPs imposes stringent limitation on processing costs. To find the numerical optimum of a predefined “low-cost” configuration, software tools have been developed in C++, which let us define a parametric model. Starting from labelling of speech material, prototypes of the phonemes to be spotted are established on the basis of a mixed statistical approach, which contains range check and a likelihoodbased distance measure in the feature space chosen.
Exploiting query logs for cross-lingual query suggestions

Query suggestion aims to suggest relevant queries for a given query, which helps users better specify their information needs. Previous work on query suggestion has been limited to the same language. In this article, we extend it to cross-lingual query suggestion (CLQS): for a query in one language, we suggest similar or relevant queries in other languages. This is very important to the scenarios of cross-language information retrieval (CLIR) and other related cross-lingual applications. Instead of relying on existing query translation technologies for CLQS, we present an effective means to map the input query of one language to queries of the other language in the query log. Important monolingual and cross-lingual information such as word translation relations and word co-occurrence statistics, and so on, are used to estimate the cross-lingual query similarity with a discriminative model. Benchmarks show that the resulting CLQS system significantly outperforms a baseline system that uses dictionary-based query translation. Besides, we evaluate CLQS with French-English and Chinese-English CLIR tasks on TREC-6 and NTCIR-4 collections, respectively. The CLIR experiments using typical retrieval models demonstrate that the CLQS-based approach has significantly higher effectiveness than several traditional query translation methods. We find that when combined with pseudo-relevance feedback, the effectiveness of CLIR using CLQS is enhanced for different pairs of languages.
