Dimensions of Business-to-Consumer (B2C) Systems Success in Kuwait: Testing a Modified DeLone and McLean IS Success Model in an E-Commerce Context

An extensive body of research has tested the information systems success model in many contexts. Surprisingly, few of these studies have applied it to e-commerce. A study by represents one such initiative, but it is crucial to address several remaining gaps associated with that study. Moreover, no e-commerce success model has considered the Arab world, which exhibits unique cultural factors influencing e-commerce. The authors' study proposes an improved IS success model for e-commerce in the Arab world. This model, based on that of, adds several enhancements to the validity and generalisability of his efforts, uses the latest SEM techniques, including both monetary and nonmonetary value conceptualisations, uses a multidimensional conceptualisation of system quality, and proposes specific factors of e-commerce service quality. The authors tested the proposed research model with a truly randomised sampling approach using 288 experienced business-to-consumer B2C consumers in the Arab world. The results largely support our hypothesised model. The most important difference between our results and those of previous studies is our finding that although service quality influences value, it has no bearing on user satisfaction in an Arab context. This study will be useful for practitioners and researchers seeking to improve the understanding of B2C e-commerce success in the Arab world.
Evidence of a MOF histone acetyltransferase-containing NSL complex in C. elegans

Regulation of chromatin is a key process in the developmental control of gene expression. Many multi-subunit protein complexes have been found to regulate chromatin through the modification of histone residues. One such complex is the MOF histone acetyltransferase-containing NSL complex. While the composition of the human and Drosophila NSL complexes has been determined and the functions of these complexes investigated, the existence of an equivalent complex in nematodes such as Caenorhabditis elegans has not yet been explored. Here we summarise evidence, from our own work and that of others, that homologues of NSL complex components are found in C. elegans. We review data suggesting that nematode proteins SUMV-1 and SUMV-2 are homologous to NSL2 and NSL3, respectively, and that SUMV-1 and SUMV-2 may form a complex with MYS-2, the worm homolog of MOF. We propose that these interactions suggest the existence of a nematode NSL-like complex and discuss the roles of this putative NSL complex in worms as well as exploring the possibility of crosstalk between NSL and COMPASS complexes via components that are common to both. We present the groundwork from which a full characterization of a nematode NSL complex may begin.
Dynamic force/torque equilibrium for stable grasping by a triple robotic fingers system

This paper proposes a stable object grasping method to realize dynamic force/torque equilibrium by using a triple robotic fingers system with soft and deformable hemispherical fingertips. In the authors' previous works, “Blind Grasping” control scheme, which realizes stable object grasping without use of any external sensing such as vision, force, or tactile sensing in the case of using a pair of robot fingers, has been proposed. This control methodology is based on a unique configuration of human hand, called “Fingers-Thumb Opposability”. In this paper, a ternary finger in addition to a pair of fingers is introduced not only to expand a stable region of grasping, but also to enhance dexterity and versatility of the multi-fingered robotic hand system. To this end, a “Blind Grasping” manner is modified in order to install it in the triple fingers system. First, dynamics of the triple robotic fingers system and a grasped object with considering rolling constraints is modeled, and a control input based on the blind grasping manner is designed. Next, the closed-loop dynamics is derived and a stability analysis is shown briefly. Finally, its usefulness is discussed through numerical simulation results.
Query Answering Using Ontologies in Agent-based Resource Sharing Environment for Biological Web Information Integrating

A variety of biological data is transferred and exchanged in overwhelming volumes on the World Wide Web. How to rapidly capture, utilize and integrate hundreds of biological databases on the Web is one of the most critical issues in bioinformatics. In this paper, we describe our preliminary study to address this issue in an agent-based resource-sharing environment, where we apply the Web agent technology and DAML+OIL ontologies of biological knowledge to enable biologists to make concept-to-concept query. Given a query, the agent coordination service in this environment will search for a set of suitable paths in the ontologies that links the query concept to the goal concept. The Web agents will be launched to extract the data from the target Web resources and transfer the data according to the found path to answer the query. This approach makes the details of querying Web resources transparent to the biologists and allows them to query biological resources on the Web in the terms of their domain knowledge.
The synthesis of active pharmaceutical ingredients (APIs) using continuous flow chemistry

The implementation of continuous flow processing as a key enabling technology has transformed the way we conduct chemistry and has expanded our synthetic capabilities. As a result many new preparative routes have been designed towards commercially relevant drug compounds achieving more efficient and reproducible manufacture. This review article aims to illustrate the holistic systems approach and diverse applications of flow chemistry to the preparation of pharmaceutically active molecules, demonstrating the value of this strategy towards every aspect ranging from synthesis, in-line analysis and purification to final formulation and tableting. Although this review will primarily concentrate on large scale continuous processing, additional selected syntheses using micro or meso-scaled flow reactors will be exemplified for key transformations and process control. It is hoped that the reader will gain an appreciation of the innovative technology and transformational nature that flow chemistry can leverage to an overall process.
Tumor-marrow index: a means of laboratory evaluation of antineoplastic compounds.

Summary A tumor-marrow index (TMI) to be used in the laboratory evaluation of anticancer agents has been defined as that dose causing 50 per cent destruction of the marrow/dose causing 80 per cent suppression of tumor growth in the same animal. Eighteen compounds (eleven antifolic acid analogs, six alkylating agents, and one antipurine) were studied, and the doses causing the effects mentioned were estimated. The TMI was used to compare analogs against the same tumor type rather than the TMI9s obtained from the same anticancer agent against different tumors. It was found that there was a marked difference between the indexes as obtained with the antifolic acid compounds against the 6C3HED lymphosarcoma and the alkylating agents against the 72j mammary adenocarcinoma. Of the former, all were 2.0 or greater; whereas of the latter, none was significantly greater than 1.0. Dichloromethotrexate was outstanding of the antifolic acid group; the TMI9s of the methotrexate derivatives were generally higher than those of the aminopterin analogs. The TMI obtained with 6-mercaptopurine against Sarcoma 180 was less than 1.0.
Video based abnormal behavior detection

In this paper, problems of breakpoint produced during motion region detection, feature selection for human behavior recognition as well as classification and identification of human behavior were studied. Problem of breakpoints was solved by means of combining background subtraction with frame difference method. Shape feature is selected by experiment as the identification indicators of human motor behavior. Refinement of the shape characteristics was made. The mass center locus and its x, y components were proved to have high recognition performance for human behavior identification and classification. On this basis, a video-based human behavior detection system was designed.
TCvisor: A hypervisor level secure storage

In this paper, we present design and implementation of TCvisor, a new trusted hypervisor. To this end, TCvisor provides a secure storage with different isolated view per user by using para-passthrough and combined key. In this regard, virtualization technology of processors has been used for complete isolation from operating system. By combining TPM base key, user's password and geo function key, TCvisor provides a secure storage in an environment with split data. We have applied feature wise security analysis TCvisor's secure storage from software system layers point then we have compared performance of TCvisor to selected candidates of existing layers.
Dissecting Alzheimer disease in Down syndrome using mouse models

Down syndrome (DS) is a common genetic condition caused by the presence of three copies of chromosome 21 (trisomy 21). This greatly increases the risk of Alzheimer disease (AD), but although virtually all people with DS have AD neuropathology by 40 years of age, not all develop dementia. To dissect the genetic contribution of trisomy 21 to DS phenotypes including those relevant to AD, a range of DS mouse models has been generated which are trisomic for chromosome segments syntenic to human chromosome 21. Here, we consider key characteristics of human AD in DS (AD-DS), and our current state of knowledge on related phenotypes in AD and DS mouse models. We go on to review important features needed in future models of AD-DS, to understand this type of dementia and so highlight pathogenic mechanisms relevant to all populations at risk of AD.
Meeting Spaces : Spaces Meeting – on the threshold of a new spatial aesthetic ?

Based on an overview of designs and technological attempts to mediate physical work and learning environments carried out within an interdisciplinary research network at the KTH, the paper will address the broader epistemological implications arising from the use of new media in the service of new paradigms based on mixed media/reality environments (‘(re)mediated environments’, ‘media space’, ‘telepresence’ etc.). Such hybrid or cybrid spaces, constituted of both physical and virtual tools, demand a resolution of contrary experiential and spatial concepts; although participants at each location experience different concepts of space they also occupy, physically and imaginatively, shared composite spaces – designs based on a juxtaposition of several physical and virtual space(s). The paper argues that new design contexts imply a new professional identity for the architect; by increased exposure to the field of media technology, the architect is invited into new interdisciplinary collaborations. This development stresses the need for a revised set of conceptual (virtual) and physical tools for contemporary designers. While modelling in virtual worlds was traditionally a means of communication towards a final physical representation, architects must now incorporate virtual or hybrid spaces within the design process and be trained accordingly with the appropriate tools, technologies, and methods. Charlie Gullström is Director for The Centre for Sustainable Communications, a new research centre at KTH, Royal Institute of Technology aiming to innovate, explore and evaluate circumstances where ICT (media & communications) can make significant contributions towards sustainability. Charlie Gullström is also a Stockholm-based architect whose architectural practice over the past 15 years has specialised in workplace design and the design of spaces in which learning, collaboration and communication are central, explicit concerns for some of Sweden's leading companies such as Ericsson, Telia, Föreningssparbanken and ICA. She is currently completing a doctoral thesis at KTH School of Architecture and the Built Environment. Her research seeks to extend our understanding of architecture through examining the contribution of new media and communication, specifically the impact of imagebased communication technology on architectural practice and the design of (distributed) work and learning environments i.e. 'hybrid' architectural spaces. The project explores the design context of collaborative work processes to illuminate the role of conceptual and modelling tools in situations where practical knowledge is sought and shared.
Sensing immersive 360° mobile interactive video

Video has the potential for a strong impact on viewers, their sense of presence and engagement, due to its immersive capacities. Multimedia sensing and the flexibility of mobility may be considered as options to further extend the video's immersive capacities. Mobile devices are becoming ubiquitous and the range of sensors and actuators they incorporate is ever increasing, which creates the potential to capture and display 360º video and metadata and to support more powerful and immersive video user experiences. In this paper, we explore the immersion potential of mobile interactive video augmented with visual, auditory and tactile multisensing. User evaluation revealed advantages in using a multisensory approach to increase immersion and user satisfaction. Also, several properties and parameters that worked better in different conditions were identified, which may help to inform design of future mobile immersive video environments.
The Cytidine Analog Fluorocyclopentenylcytosine (RX-3117) Is Activated by Uridine-Cytidine Kinase 2

Fluorocyclopentenylcytosine (RX-3117) is an orally available cytidine analog, currently in Phase I clinical trial. RX-3117 has promising antitumor activity in various human tumor xenografts including gemcitabine resistant tumors. RX-3117 is activated by uridine-cytidine kinase (UCK). Since UCK exists in two forms, UCK1 and UCK2, we investigated which form is responsible for RX-3117 phosphorylation. For that purpose we transfected A549 and SW1573 cell lines with UCK-siRNAs. Transfection of UCK1-siRNA efficiently downregulated UCK1-mRNA, but not UCK2-mRNA expression, and did not affect sensitivity to RX-3117. However, transfection of UCK2-siRNA completely downregulated UCK2-mRNA and protein and protected both A549 and SW1573 against RX-3117. UCK enzyme activity in two panels of tumor cell lines and xenograft cells correlated only with UCK2-mRNA expression (r = 0.803 and 0.915, respectively), but not with UCK1-mRNA. Moreover, accumulation of RX-3117 nucleotides correlated with UCK2 expression. In conclusion, RX-3117 is activated by UCK2 which may be used to select patients potentially sensitive to RX-3117.
Instability of Relevance-Ranked Results Using Latent Semantic Indexing for Web Search

The latent semantic indexing (LSI) methodology for information retrieval applies the singular value decomposition to identify an eigensystem for a large matrix, in which cells represent the occurrence of terms (words) within documents. This methodology is used to rank text documents, such as Web pages or abstracts, based on their relevance to a topic. The LSI was introduced to address the issues of synonymy (different words with the same meaning) and polysemy (the same words with multiple meanings), thus addressing the ambiguity in human language by utilizing the statistical context of words. Rather than keeping all k possible eigenvectors and eigenvalues from the singular value decomposition which approximates the original term by document matrix, a smaller number is used - essentially allowing a fuzzy match of a topic to the original term by document matrix. In this paper, we show that the choice k impacts the resultant ranking and there is no value of k that results in stability of ranked results for similarity of the topic to documents. This is a surprising result, because prior literature indicates that eigensystems based on successively large values of k should approximate the complete (max k) eigensystems. The finding that document-query similarity rankings with larger values of k do not, in fact, maintain consistency, makes it difficult to assert that any particular value of k is optimal. This in turn renders LSI potentially untrustworthy for use in ranking text documents, even for values that differ by only 10% of the max k.
Topologically adaptable snakes

The paper presents a typologically adaptable snakes model for image segmentation and object representation. The model is embedded in the framework of domain subdivision using simplicial decomposition. This framework extends the geometric and topological adaptability of snakes while retaining all of the features of traditional snakes, such as user interaction, and overcoming many of the limitations of traditional snakes. By superposing a simplicial grid over the image domain and using this grid to iteratively reparameterize the deforming snakes model, the model is able to flow into complex shapes, even shapes with significant protrusions or branches, and to dynamically change topology as necessitated by the data. Snakes can be created and can split into multiple parts or seamlessly merge into other snakes. The model can also be easily converted to and from the traditional parametric snakes model representation. We apply a 2D model to various synthetic and real images in order to segment objects with complicated shapes and topologies. <<ETX>>
Estimating heat transfer coefficients as a function of temperature by data mining

This paper describes our proposed technique AutoDomainMine that performs data mining guided by fundamental knowledge of the domain. The data being mined consists of input conditions from quenching experiments and the resulting heat transfer curves, i.e., plots of heat transfer coefficients versus part temperature. Since heat transfer coefficients characterize quenching, the estimation assists decision-making. This avoids running laboratory experiments which consume considerable time and resources. AutoDomainMine integrates two data mining techniques, clustering and classification, into a learning strategy. It clusters curves resulting from existing experiments and uses decision tree classifiers to learn the clustering criteria, i.e., input conditions characterizing the clusters. The learned criteria are used to design a representative pair of input conditions and heat transfer curve per cluster. The decision trees and representatives serve as the basis for estimation. When input conditions of an unperformed experiment are submitted, the decision tree path is traced to estimate its cluster and hence the corresponding heat transfer curve. Also when a desired heat transfer curve is submitted, it is compared with the representative curves. The input conditions of the closest matching curve are the estimated conditions to achieve the desired curve. AutoDomainMine on evaluation gives accuracy higher than state-of-the-art estimation techniques.
Reasoning with PCP-nets in a Multi-Agent Context

PCP-nets generalize CP-nets to model conditional preferences with probabilistic uncertainty. In this paper we use PCP-nets in a multi-agent context to compactly represent a collection of CP-nets, thus using probabilistic uncertainty to reconcile possibly conflicting qualitative preferences expressed by a group of agents. We then study two key preference reasoning tasks: finding an optimal outcome which best represents the preferences of the agents, and answering dominance queries. Our theoretical and experimental analysis demonstrates that our techniques are efficient and accurate for both reasoning tasks.

Parental Acceptance and Rejection: Theory, Measures, and Research in the Arab World.

Purpose. The purpose of this article is to summarize the rich and growing body of research that draws from parental acceptance-rejection theory (PARTheory) and associated measures as used throughout the Arab world. Methodology. This body of work includes more than 100 studies that explore the reliability and validity of Arabic adaptations of several measures of parental acceptance-rejection, antecedents of acceptance-rejection, and mental health and educational consequences of perceived acceptance-rejection in the Arab world. Results. Overall, Arab research provides strong support for the pan-Arab applicability of PARTheory and the research instruments derived from it. Conclusions and Recommendations. Evidence provided in this review tends to be so robust and so consistent that we believe educators, psychologists, and other professionals should feel confident developing policies and practice-applications based on PARTheory and its associated measures in the Arab world. For example, Arab educators, psychologists, and others might consider preparing written and visual materials based on evidence provided here that would provide advice and guidance to parents and other members of the general public for helping promote educational achievement and optimal mental health in children and adults throughout the Arab world.

Found in (survey) translation: lessons learned while engaging with a wharekura in Southland, New Zealand

ABSTRACT We liaised with a wharekura (Māori language immersion school) to translate and disseminate an online survey for a group of Māori youth in Southland, New Zealand (NZ). The focus of this article is not results, but the processes of respondent orientation and engagement to more genuinely include Māori in a youth survey. An online survey about transport and well-being was conducted with older teenagers from 12 schools, including the wharekura. After working with wharekura staff and students, the survey was translated from English into te reo Māori using best-practice methods. Steps were taken to safeguard authentic engagement, including how the survey translation was conducted, and how the survey data were shared. This NZ-specific experience adds to the literature about the practice of applying the principle of respondent orientation to the process of translating an existing survey into te reo Māori, demonstrating commitment to some Treaty of Waitangi principles. While this is not a kaupapa Māori research project, it is informed by some kaupapa Māori principles. This may be seen as a limitation of this work; however, we believe there are many positive experiences and lessons to be learned from our approach.
