The Possibility of One-Size-Fits-All in ICT4D Design: A Case Study of the Day-Labour Organisations

This paper presents design experiences for two Non-Governmental organizations and one day-labour organisation working for the informal job seekers and employers-day-labour market. The authors present the three design architectures implemented for the organisations and show that, even when users are portrayed as similar in the way they work and what they do, their Information Management Systems IMS functional software requirements remain contextual up to the details. The authors argue that, although non-functional requirements may be the same for seemingly similar users, there is need to focus on the different functional information needs, including the ones that may seem insignificant. They noted that designers need to know more about their users beyond the "about us" information. The authors conclude that there exists no "one size fits all" IMS, even for seemingly similar organisations.
3D Extended Histogram of Oriented Gradients (3DHOG) for Classification of Road Users in Urban Scenes

This paper proposes and demonstrates a novel method for the detection and classification of individual vehicles and pedestrians in urban scenes. In this scenario, shadows, lights and various occlusions compromise the accuracy of foreground segmentation and hence there are challenges with conventional silhouette-based methods. 2D features derived from histograms of oriented gradients (HOG) have been shown to be effective for detecting pedestrians and other objects. However, the appearance of vehicles varies substantially with the viewing angle and local features may be often occluded. In this paper, a novel method is proposed that overcomes limitations in the use of 2D HOG. Full 3D models are used for the object categories to be detected and the feature patches are defined over these models. A calibrated camera allows an affine transform of the observation into a normalised representation from which ‘3DHOG’ features are defined. A variable set of interest points is used in the detection and classification processes, depending on which points in the 3D model are visible. Experiments on real CCTV data of urban scenes demonstrate the proposed method. The 3DHOG feature is compared with features based on FFT and simple histograms. A baseline method using overlap between wire-frame models and motion silhouettes is also included. The results demonstrate that the proposed method achieves comparable performance. In particular, an advantage of the proposed method is that it is more robust than motion silhouettes which are often compromised in real data by variable lighting, camera quality and occlusions from other objects.
External IT environment: dimensionality and measurement

Although the importance of the external IT environment has been recognized in the literature, there has been little effort to conceptualize the theoretical dimensions of this construct and develop operational indicators to measure it. Our research addresses this gap and seeks to develop the theoretical dimensions and operational measures for external IT environment and empirically validate them. We use qualitative data obtained from interviews with 27 senior IT executives to identify three broad dimensions of external IT environment—namely, IT munificence, IT dynamism, and IT activity intensity. Operational measures for these dimensions were also developed from qualitative research. Subsequently, an instrument was developed to empirically measure the dimensions of the external IT environment. The validity of the dimensions and its operational indicators are being tested with data collected from a survey of 223 IT executives.
Organizing Information On The Next Generation Web -- Design And Implementation Of A New Bookmark Structure

The next-generation Web will increase the need for a highly organized and ever evolving method to store references to Web objects. These requirements could be realized by the development of a new bookmark structure. This paper endeavors to identify the key requirements of such a bookmark, specifically in relation to Web documents, and sets out a suggested design through which these needs may be accomplished. A prototype developed offers such features as the sharing of bookmarks between users and groups of users. Bookmarks for Web documents in this prototype allow more specific information to be stored such as: URL, the document type, the document title, keywords, a summary, user annotations, date added, date last visited and date last modified. Individuals may access the service from anywhere on the Internet, as long as they have a Java-enabled Web browser.
PRIMORDIAL MAGNETIC FIELDS

The explanation of the observed galactic magnetic fields may require the existence of a primordial magnetic field. Such a field may arise during the early cosmological phase transitions, or because of other particle physics related phenomena in the very early universe reviewed here. The turbulent evolution of the initial, randomly fluctuating microscopic field to a large-scale macroscopic field can be described in terms of a shell model, which provides an approximation to the complete magnetohydrodynamics. The results indicate that there is an inverse cascade of magnetic energy whereby the coherence of the magnetic field is increased by many orders of magnitude. Cosmological seed fields roughly of the order of 10-20 G at the scale of protogalaxy, as required by the dynamo explanation of galactic magnetic fields, thus seem plausible.
Slotted substrate integrated waveguide phase shifter

The slotted substrate integrated waveguide (SSIW) phase shifter with periodic loading varactors is presented. With appropriate numbers of varactors placed on the SIW's surface, the phase of two-port device could be varied with the varactors' capacitance, which is inversely proportional to the bias voltage. To prove it, a phase shifter installed seventeen varactors has been designed. There are good agreements between simulated results and experimental ones. In the frequency bandwidth of 2.5 to 3.45 GHz (about 31.9% relative bandwidth), the return loss and inserted loss are mostly better than 10 dB and 5 dB, respectively. At the center frequency of 3GHz, the maximum phase range of 80° is obtained.
Improving Index Maintenance Using Decision Analysis

One of the main activities of a Database Administrator (DBA) is to maintain an appropriate index configuration. However, adjustments in index configuration have become a very complex decision problem for DBAs. Making decisions concerning index maintenance often strains human cognitive capabilities. The DBA is faced with an intractable amount of factors that can impact the result of his/her decision. In order to address this issue a Decision Support System (DSS) can be used to support DBA decisions based on rational and systematic procedures. A DSS can model the chances of success of each DBA’s adjustment and the risk acceptance level of each decision maker using a probabilistic framework. This article presents a Decision Support Mechanism for Index Maintenance (DSIM), whose main feature is to provide a DSS to the problem of choosing the best point in time to maintain indexes for quasi-periodic time-consuming SQL queries. DSIM provides a risk acceptance configuration feature using a probabilistic framework. Experiments show that DSIM can be effectively deployed to support DBA’s decisions.
PaSTeL: Parallel Runtime and Algorithms for Small Datasets

In this paper, we put forward PaSTeL, an engine dedicated to parallel algorithms. PaSTeL offers both a programming model, to build parallel algorithms and an execution model based on work-stealing. Special care has been taken on using optimized thread activation and synchronization mechanisms. In order to illustrate the use of PaSTeL a subset of the STL's algorithms was implemented, which were also used on performance experiments. PaSTeL's performance is evaluated on a laptop computer using two cores, but also on a 16 cores platform. PaSTeL shows better performance than other implementations of the STL, especially on small datasets.
An Analysis of Online Shopping Intention of Chinese Consumers and its Influencing Factors

This paper utilizes 587 sample data collected from three cities-Shanghai, Nanjing and Wuxi, adopts the theory of planned behavior(TPB) to study consumers' online shopping behaviors and builds the Logit model, then based on which Eviews5.0 statistical software is employed to process sample data by Logit regression. The result of our study indicates that online shopping intention of consumers is more affected by factors like income, network usage capability and the security of online shopping and less affected by such factors as consumers' age, education level and convenience.
The “Pink Pound” in the “Gaybourhood”? Neighbourhood Deprivation and Sexual Orientation in Scotland

Abstract The emergence of geographic concentrations of non-heterosexual individuals – so-called “gaybourhoods” – is often linked to housing, demographic characteristics of the non-straight population and wider discrimination. These neighbourhoods are associated with narratives of gentrification with the non-straight population acting as gentrification pioneers. In popular imagery, non-straight households are typically portrayed with higher disposable income, and more likely to live in owner-occupied apartments in affluent neighbourhoods. This paper presents data from the Scottish Health Survey showing a disproportionate concentration of non-heterosexual people in the most deprived places in Scotland. These neighbourhoods are predominantly peripheral housing estates, dominated by social housing; not gentrifying inner-city neighbourhoods. We use data from the Scottish Health Survey (SHeS) to interrogate individual characteristics that might explain this spatial concentration of residence. We argue this means the narratives of LGBT gentrification and affluence should be regarded with caution given ongoing exclusion and deprivation among the non-heterosexual population.
Magnetism in pre-MS intermediate-mass stars and the fossil field hypothesis

Today, one of the greatest challenges concerning the Ap/Bp stars is to understand the origin of their slow rotation and their magnetic fields. The favoured hypothesis for the latter is the fossil field, which implies that the magnetic fields subsist throughout the different evolutionary phases, and in particular during the pre-main sequence phase. The existence of magnetic fields at the pre-main sequence phase is also required to explain the slow rotation of Ap/Bp stars. However, until recently, essentially no information was available about the magnetic properties of intermediate-mass pre-main sequence stars, the so-called Herbig Ae/Be stars. The new high-resolution spectropolarimeter ESPaDOnS, installed in 2005 at the Canada-France-Hawaii telescope, provided the capability necessary to perform surveys of the Herbig Ae/Be stars in order to investigate their magnetism and rotation. These investigations have resulted in the detection and/or confirmation of magnetic fields in 8 Herbig Ae/Be stars, ranging in mass from 2 to nearly 15 solar masses. In this contribution I will present the results of our survey, as well as their implications for the origin and evolution of the magnetic fields and rotation.

A Critical Review of Learning from the Market: Integrating The Stock Market Game across the Curriculum

Abstract Learning from the Market: Integrating The Stock Market Game across the Curriculum is a guide for teachers of economics, mathematics, social studies, and language arts in grades 4 to 12. The author believes that Learning from the Market suffers from errors of fact and omission that seriously detract from its usefulness as a guide to the stock market and the economy. He suggests corrections and alternative activities that will enable instructors to continue to use the guide in conjunction with ever-popular stock market simulations.
Impact of urbanization and gardening practices on common butterfly communities in France

Abstract We investigated the interacting impacts of urban landscape and gardening practices on the species richness and total abundance of communities of common butterfly communities across France, using data from a nationwide monitoring scheme. We show that urbanization has a strong negative impact on butterfly richness and abundance but that at a local scale, such impact could be mitigated by gardening practices favoring nectar offer. We found few interactions among these landscape and local scale effects, indicating that butterfly‐friendly gardening practices are efficient whatever the level of surrounding urbanization. We further highlight that species being the most negatively affected by urbanization are the most sensitive to gardening practices: Garden management can thus partly counterbalance the deleterious effect of urbanization for butterfly communities. This holds a strong message for park managers and private gardeners, as gardens may act as potential refuge for butterflies when the overall landscape is largely unsuitable.
Potentially Traumatic Events, Posttraumatic Stress Disorder, and Depression among Adults in Puerto Rico

The aims of the current study were to examine the prevalence of potentially traumatic events (PTEs), posttraumatic stress disorder (PTSD; data available in males only), and depressive symptoms in a Puerto Rican sample of 678 adult caretakers (50% female) of twins participating in the Puerto Rican Infant Twin Study. The World Health Organization Composite International Diagnostic Interview version 3.0 (CIDI 3.0) was utilized to assess rates of PTEs, PTSD, and depression among male participants while an abbreviated version of the CIDI 3.0 and the Mood and Feelings Questionnaire were administered to females to assess PTEs and depressive symptoms. Significantly more males than females reported exposure to a PTE (76.6% vs. 44.2%, χ2 = 64.44, p < 0.001). In males, endorsement of multiple PTEs was associated with increased level of PTSD symptomatology (β = 0.33, p < 0.001). With regard to depression, a similar dose-response relationship was found in both males and females, with depressive symptoms increasing as number of PTEs increased (βs = 0.15, 0.16, ps < 0.05). Exposure to an attack with a weapon was significantly associated with increased depression symptoms in both males and females (βs = 0.24, 0.20, ps < 0.01, respectively). These findings highlight the need for identification of putative risk and resilience factors among PTE-exposed individuals in Puerto Rico.
Global Hadamard form for the Green function in Schwarzschild spacetime

The retarded Green function of a wave equation on a 4-dimensional curved background spacetime is a (generalized) function of two spacetime points and diverges when these are connected by a null geodesic. The Hadamard form makes explicit the form of this divergence but only when one of the points is in a normal neighbourhood of the other point. In this paper we derive a representation for the retarded Green function for a scalar field in Schwarzschild spacetime which makes explicit its {\it complete} singularity structure beyond the normal neighbourhood. We interpret this representation as a sum of Hadamard forms, the summation being taken over the number of times the null wavefront has passed through a caustic point: the sum of Hadamard forms applies to the non-smooth contribution to the full Green function, not only the singular contribution. (The term non-smooth applies modulo the causality-generating step functions that must appear in the retarded Green function.) The singularity structure is determined using two independent approaches, one based on a Bessel function expansion of the Green function, and another that exploits a link between the Green functions of Schwarzschild spacetime and Pleba{\'n}ski-Hacyan spacetime (the latter approach also yields another representation for the {\it full} Schwarzschild Green function, not just for its non-smooth part). Our representation is not valid in a neighbourhood of caustic points. We deal with these points by providing a separate representation for the Green function in Schwarzschild spacetime which makes explicit its (different) singularity structure at caustics of this spacetime.
A Survey of Computational Treatments of Biomolecules by Robotics-Inspired Methods Modeling Equilibrium Structure and Dynamic

More than fifty years of research in molecular biology have demonstrated that the ability of small and large molecules to interact with one another and propagate the cellular processes in the living cell lies in the ability of these molecules to assume and switch between specific structures under physiological conditions. Elucidating biomolecular structure and dynamics at equilibrium is therefore fundamental to furthering our understanding of biological function, molecular mechanisms in the cell, our own biology, disease, and disease treatments. By now, there is a wealth of methods designed to elucidate biomolecular structure and dynamics contributed from diverse scientific communities. In this survey, we focus on recent methods contributed from the Robotics community that promise to address outstanding challenges regarding the disparate length and time scales that characterize dynamic molecular processes in the cell. In particular, we survey robotics-inspired methods designed to obtain efficient representations of structure spaces of molecules in isolation or in assemblies for the purpose of characterizing equilibrium structure and dynamics. While an exhaustive review is an impossible endeavor, this survey balances the description of important algorithmic contributions with a critical discussion of outstanding computational challenges. The objective is to spur further research to address outstanding challenges in modeling equilibrium biomolecular structure and dynamics.
Joint distribution of distances in random regular networks

We study the array of point-to-point distances in random regular graphs equipped with exponential edge-lengths. We consider the regime where the degree is kept fixed while the number of vertices tends to infinity. The marginal distribution of an individual entry is now well-understood, thanks to the work of Bhamidi, van der Hofstad and Hooghiemstra (2010). The purpose of this note is to show that the whole array, suitably recentered, converges in the weak sense to a rather simple infinite random array. Our proof consists in analyzing the invasion of the network by several mutually exclusive flows emanating from different sources and propagating simultaneously at the same speed along the edges (competing first-passage percolation). The result applies to both the random regular multigraph produced by the configuration model and the uniform regular simple graph. AMS 2000 subject classifications: 60C05, 05C80, 90B15.
A Novel Method for Measuring Anterior Segment Area of the Eye on Ultrasound Biomicroscopic Images Using Photoshop

Purpose To describe a novel method for quantitative measurement of area parameters in ocular anterior segment ultrasound biomicroscopy (UBM) images using Photoshop software and to assess its intraobserver and interobserver reproducibility. Methods Twenty healthy volunteers with wide angles and twenty patients with narrow or closed angles were consecutively recruited. UBM images were obtained and analyzed using Photoshop software by two physicians with different-level training on two occasions. Borders of anterior segment structures including cornea, iris, lens, and zonules in the UBM image were semi-automatically defined by the Magnetic Lasso Tool in the Photoshop software according to the pixel contrast and modified by the observers. Anterior chamber area (ACA), posterior chamber area (PCA), iris cross-section area (ICA) and angle recess area (ARA) were drawn and measured. The intraobserver and interobserver reproducibilities of the anterior segment area parameters and scleral spur location were assessed by limits of agreement, coefficient of variation (CV), and intraclass correlation coefficient (ICC). Results All of the parameters were successfully measured by Photoshop. The intraobserver and interobserver reproducibilities of ACA, PCA, and ICA were good, with no more than 5% CV and more than 0.95 ICC, while the CVs of ARA were within 20%. The intraobserver and interobserver reproducibilities for defining the spur location were more than 0.97 ICCs. Although the operating times for both observers were less than 3 minutes per image, there was significant difference in the measuring time between two observers with different levels of training (p<0.001). Conclusion Measurements of ocular anterior segment areas on UBM images by Photoshop showed good intraobserver and interobserver reproducibilties. The methodology was easy to adopt and effective in measuring.
