Why People Continue Use EC ?

With the dramatically develop Internet in businesses which have become a new medium to interact with customers, the challenges for Web site companies are how to design good Web system and interaction in order to retain customers and increase sales. However, customers' shopping behaviors on World Wide Web (WWW) are still inconclusive. In the compelling online environment, understanding how online consumers act is important in today's digital economy. Therefore, it is important to know to retain consumers' to shop on-line. In this study, we use Interactive Qualitative Analysis (IQA) approach to draw experienced EC consumers' mindmap to understand why they continue to shop online. There are some finds and the implications are discussed. In addition, some managerial problem may be concerned.
Research and Implementation of 3D Modeling Algorithm Based on Image

In this paper, based on the in-depth research of the existing 3D modeling methods, a new 3D modeling method based on image is presented. This method can generate a 3D model with a high precision by using less human-computer interaction workload and less image demand. The 3D model established by using this method is not only efficient but also easier to achieve realistic rendering and virtual reality applications. The experiment results show that the method is feasible and has good results for processing the 3D image, so it has a certain practical value.
Programming Cloud Resource Orchestration Framework: Operations and Research Challenges

The emergence of cloud computing over the past five years is potentially one of the breakthrough advances in the history of computing. It delivers hardware and software resources as virtualization-enabled services and in which administrators are free from the burden of worrying about the low level implementation or system administration details. Although cloud computing offers considerable opportunities for the users (e.g. application developers, governments, new startups, administrators, consultants, scientists, business analyst, etc.) such as no up-front investment, lowering operating cost, and infinite scalability, it has many unique research challenges that need to be carefully addressed in the future. In this paper, we present a survey on key cloud computing concepts, resource abstractions, and programming operations for orchestrating resources and associated research challenges, wherever applicable.
Role of Lipooligosaccharide in Opa-Independent Invasion of Neisseria gonorrhoeae into Human Epithelial Cells

Lipooligosaccharide (LOS) has been implicated in the adhesion and invasion of host epithelial cells. We examined the adhesive and invasive abilities of isogenic gonococcal opacity-associated outer membrane protein–negative, pilus-positive (Opa−Pil+) Neisseria gonorrhoeae strains expressing genetically defined LOS. Strain F62 (Opa−Pil+), expressing the lacto-N-neotetraose and the galNac-lacto-N-neotetraose LOS, and its isogenic derivative that expressed only the lacto-N-neotetraose LOS (F62ΔlgtD), adhered to, and invaded, to the same extent the human cervical epidermoid carcinoma cell line, ME180. While the adhesive abilities of Opa−Pil+ isogenic strains that express LOS molecules lacking the lacto-N-neotetraose structure were similar to that seen for F62, their invasive abilities were much lower than the strains expressing lacto-N-neotetraose. Fluorescence microscopy studies showed that the adherence of F62, but not the strains lacking lacto-N-neotetraose, induced the rearrangement of actin filaments under the adherent sites. Electron microscopy studies demonstrated that F62, but not the strains lacking lacto-N-neotetraose, formed extensive and intimate associations with epithelial cell membranes. Thus, in the absence of detectable Opa protein, the lacto-N-neotetraose LOS promotes gonococcal invasion into ME180 cells. The data also suggest that LOS is involved in the mobilization of actin filaments in host cells, and in the formation of a direct interaction between the bacterial outer membrane and the plasma membrane of ME180 cells.

Based on the result of the data analysis, it was found that 6 students (14.63%) had high level to use the learning style in learning English. They are cognitive, sensory and personality learning style. It means that most students always or often use three kinds of learning style. There were 33 students (80.49%) had middle level. It means that the students sometimes use three kinds of learning style. There were 2 students (4.88%) had low level. It means that the students rarely and never use three kinds of learning style. The finding of this research lead the researcher to conclude that students sometimes use learning style in learning English. Based on the conclusion, it is suggested to the teacher to motivate students to use learning style; cognitive learning style, sensory learning style and personality learning style in high level to improve their learning achievement.
Determinants of Information Technology Outsourcing: A Cross-Sectional Analysis

Abstract:This paper develops and tests a model of the determinants of information technology (IT) outsourcing by integrating both business and IT perspectives. Specifically, we attempt to explain the degree of IT outsourcing using business and IT competences as represented by their cost structures and economic performances. In addition, we posit that outsourcing is dependent on business governance, particularly financial leverage. Based on factor analyses and multiple regressions using data from fIfty-five major U.S. corporations, we observed that the degree of IT outsourcing is positively related to both business and IT cost structures. We also established that the degree ofIT outsourcing is negatively related to IT performance. Finally, we conclude with implications and future research directions.
17 β-HYDROXYSTEROID DEHYDROGENASES / 17-KETOSTEROID REDUCTASES ( 17 HSD / KSRS ) IN PROSTATE CANCER

Prostate cancer is the most frequently diagnosed cancer in men in industrialized countries. Despite the substantial clinical importance of the disease, the mechanisms underlying the development and progression of prostate cancer are poorly understood. In the present study, fragment analysis of chromosome arm 16q was carried out with the aim of searching for sites of consistent chromosomal deletion, possibly uncovering the location of target genes that become inactivated in prostate carcinogenesis. The highest percentage of loss of heterozygosity (LOH) was found at chromosomal region 16q24.1-q24.2, including the gene for 17βhydroxysteroid dehydrogenase/17-ketosteroid reductase (17HSD/KSR) type 2, HSD17B2. The data further indicated an association between loss of the most commonly deleted region and clinically aggressive features of the disease. A fragment analysis performed using sequential primary and locally recurrent prostate cancer specimens suggested the location of the genes related to prostate cancer progression to be at 16q24.3 and, further, gave rise to a hypothesis of the potential role of locus HSD17B2 as a prognostic marker for prostate cancer progression. Quantitative real-time polymerase chain reaction (PCR) revealed a decreased HSD17B2 gene copy number in prostate cancer specimens compared to their normal counterparts. A diminished HSD17B2 gene copy number was significantly associated with poor differentiation of the tumor. The progression of prostate cancer during androgen deprivation is a serious clinical problem, the molecular mechanisms of which largely remain to be clarified. The present data of enzyme activity measurements performed using high-performance liquid chromatography (HPLC) provided evidence of a substantial decrease in oxidative and an increase in reductive 17HSD/KSR activity during the transition of prostate cancer LNCaP cells into an androgen-independent state. Further, the changes detected in the activities largely coincided with the changes in the relative expression levels of genes for the potential 17HSD/KSR isoenzymes; 17HSD/KSR types 2, 5, and 7, as evidenced by relative quantitative reverse transcription PCR (RT-PCR). The data on the expression analysis of mRNA for 17HSD/KSR types 5 and 7 in prostate tissue specimens performed using in situ hybridization showed a moderately low but constitutive level for 17HSD/KSR7 mRNA in tissues of cancerous as well as hyperplastic origin. The expression of mRNA for 17HSD/KSR type 5, instead, varied considerably between different specimens, the highest expressions being strongly associated with aggressive and metastatic prostate cancer. Interestingly, furthermore, the intense expression of 17HSD/KSR5 was significantly associated with the androgen deprivation achieved either surgically or medically. Since 17HSD/KSRs critically contribute to the control of the bioavailability of active sex steroid hormones locally in the prostate, the variation in intraprostatic 17HSD/KSR activity might be crucially involved in the regulation of the growth and function of the organ.
Adhesion in development: an historical overview.

My purpose here is to provide brief historical overviews of three related subjects conceptually fundamental to the broader subject of "cell adhesion in development. " These subjects are (1) the evolution of our present understanding of how animal cells cohere; (2) the question of what principles underlie the ability of embryonic cell populations to organize themselves into anatomically correct structures; and (3) the ongoing effort to understand the origins of the "recognition specificity" evinced in the latter phenomenon. Because this review must be brief, it is not possible to mention all of the significant advances, many of which will be referenced in a recent more detailed review of this subject (Grunwald, 1991). For the same reason, the important work on cell adhesion in nonvertebrate systems is not included.
Artist intermediaries in Berlin: cultural intermediation as an interscalar strategy of self-organizational survival

This paper argues that intermediation is both a valuable form of occupational self-organization for professional artists and a political act of embedding with socio-spatial ramifications at different local, urban, and global scales. A case study of events organized in Berlin by the interdisciplinary cultural centre Zentrum für Kunst und Urbanistik demonstrates how artists strategically practice intermediation as modes of autopoietic and dissipative self-organization and as an interscalar survival strategy. These artist intermediaries add improvisational flexibility to the state’s understanding of Verstetigung (sustainable anchoring that fosters a reliable relationship between urban policymakers and cultural producers) and challenge neoliberal urban development logics that instrumentalize creativity.
Sparse Max-Margin Multiclass and Multi-label Classifier Design for Fast Inference

We address the problems of sparse multiclass and multilabel classifier design and devise new algorithms using margin based ideas. Many online applications such as image classification or text categorization demand fast inference. State-of-the-art classifiers such as Support Vector Machines (SVM) are not preferred in such applications because of slow inference, which is mainly due to the large number of support vectors required to form the SVM classifier. We propose algorithms which solve primal problems directly by greedily adding the required number of basis functions into the classifier model. Experiments on various real-world data sets demonstrate that the proposed algorithms output significantly smaller number of basis functions, while achieving nearly the same generalization performance as that given by SVM and other state-of-the-art sparse classifiers. This enables the classifiers to perform faster inference, thereby making the proposed algorithms powerful alternatives to existing
MV-TMM: Une approche multi vues pour la gestion de la traçabilité des exigences

Apres une etude de l‘etat de l‘art dans le domaine de la tracabilite des exigences, nous avons constate que la gestion de la tracabilite a fait l‘objet de plusieurs travaux de recherche. Malgre ces travaux, nous avons constate que les entreprises rencontrent encore des difficultes a integrer la tracabilite dans leurs processus de developpement. Cela est du au manque de mecanisme de representation des differents types d‘informations de tracabilite ainsi qu‘a la meconnaissance du processus de tracabilite des exigences dans un projet. Le travail de cette these propose une solution denommee MV-TMM (un demarche multi vues pour la gestion de la tracabilite) composee de deux elements principaux : (i) un meta modele multi vues permettant la representation des differents types d‘informations de tracabilite et (ii) un processus intentionnel decrivant les etapes necessaires pour la construction et l‘usage des informations de tracabilite.
Social and Demographic Predictors of Preschoolers' Bedtime Routines

Objective: To examine the associations of child and family sociodemographic characteristics with preschooler bedtime routines. Method: We use parent-report data of 3217 3-year-old children (48% black, 26% Hispanic, and 22% white) from the Fragile Families and Child Wellbeing Study to examine whether child and family characteristics are associated with the presence, time, and consistency of bedtime routines. Results: More than 80% of sample children have a bedtime yet only two thirds follow it. After extensive controls for maternal education, family structure, and other household characteristics, black and Hispanic children have later bedtimes than white children and reduced odds of using regular bedtimes (by 22% and 29%, respectively) and using bedtime routines (by 47% and 33%, respectively). Low maternal education, increased household size, and poverty are associated with decreased use of parent-child interactive and hygiene-related bedtime routines. Conclusion: Children from disadvantaged households are less likely to have consistent bedtime routines than their more advantaged counterparts. This may contribute to later disparities in sleep quality, duration and timing, factors known to be associated with adverse behavioral, cognitive, and health outcomes.
Feature extraction using graph discriminant embedding

Marginal fisher analysis (MFA) is an effective approach for feature extraction and recognition. However, an intrinsic limitation existed in MFA is that it deemphasizes the importance of the distant points, which may degrade the recognition performance. In this paper, a novel algorithm called graph discriminant embedding (GDE) is proposed to overcome the limitation. GDE maintains the good property of MFA and emphasizes the importance of the distant points as well as that of the nearby points, seeking to find a set of optimal directions to maximize the inter-class scatter and simultaneously minimize the intra-class scatter. Experimental results on the ORL and Yale face databases show the effectiveness of the proposed algorithm.
Complex Traditional Chinese Medicine for Poststroke Motor Dysfunction: A Systematic Review

Background and Purpose— For its current dimensions, stroke represents the world’s primary health challenge. In China stroke is the second most common cause of death. Traditional Chinese Medicine (TCM) has for many centuries been used, and it is still widely used today in countries of south and east Asia for the treatment of people with stroke. The objective of this systematic review was to evaluate whether complex Traditional Chinese Medicine (cTCM) improves poststroke motor recovery. In particular, we defined cTCM as intervention that included at least acupuncture and Chinese herbal medicine. Methods— An extensive search including PubMed, EMBASE, CBM, and the Cochrane Library was performed up to December 2007. Randomized clinical trials (RCTs) about cTCM for motor dysfunction of poststroke were searched irrespective of any language. The quality of each trial was assessed according to the Cochrane Reviewers’ Handbook 4.2. 6. Results— After selection of 11 234 articles, 34 RCTs and quasi-RCTs were included. All these trials were conducted in China and published on Chinese journals. All trials but one reported results in favor of cTCM treatments suggesting a strong publication bias. Because of the significant clinical and methodological heterogeneity, no meta-analysis was performed and thus no cumulative result was obtained pooling data of RCTs. Conclusions— What appears from this systematic review is that scant data are available to evaluate efficacy of cTCM for poststroke motor dysfunction. Most of the primary studies available for this review were inadequately designed trials characterized by unknown dropout rates and definitional vagueness in outcomes measures. None of the studies approached important end points like death, survival times, rate of dependency, reduction in length of stay in hospital, etc. The key to lead to evidence-based practices is establishing a consensus on standardized relevant outcome measures and then designing and conducting appropriate RCTs that adopt those standards.
Denken over veranderen in vijf kleuren

Het woord veranderen is te typeren als een containerbegrip. Als je op zoek gaat naar de achterliggende waarden en betekenissen van het woord kom je een scala van begrippen tegen. Het woord veranderen wordt bijvoorbeeld gebruikt om de gewenste uitkomst te omschrijven (het doel, product, resultaat, effect); wat klaar is, wat gerealiseerd is of wat tot stand gebracht is. Dat zie je in zinsnedes als: “Deze verandering is duidelijk zichtbaar”. “Het gebouw is heel erg veranderd”. “Piet is heel erg veranderd”. Maar ook wordt het woord veranderen gebruikt voor het proces (plan van aanpak, werkwijze, weg, activiteiten); de overgang van de ene toestand naar een andere; het veranderingsproces. Dat zie je in zinsnedes als: “De verandering is nog bezig”, “We zijn het gebouw aan het veranderen”, “Piet verandert”.
A Cache Management Scheme for Efficient Content Eviction and Replication in Cache Networks

To cope with the ongoing changing demands of the internet, ‘in-network caching’ has been presented as an application solution for two decades. With the advent of information-centric network (ICN) architecture, ‘in-network caching’ becomes a network level solution. Some unique features of the ICNs, e.g., rapidly changing cache states, higher request arrival rates, smaller cache sizes, and other factors, impose diverse requirements on the content eviction policies. In particular, eviction policies should be fast and lightweight. In this paper, we propose cache replication and eviction schemes, conditional leave cope everywhere (CLCE) and least frequent recently used (LFRU), which are well suited for the ICN type of cache networks (CNs). The CLCE replication scheme reduces the redundant caching of contents; hence improves the cache space utilization. LFRU approximates the least frequently used scheme coupled with the least recently used scheme and is practically implementable for rapidly changing cache networks like ICNs.
An overview of COMMON LISP

A dialect of LISP called “COMMON LISP” is being cooperatively developed and implemented at several sites. It is a descendant of the MACLISP family of LISP dialects, and is intended to unify the several divergent efforts of the last five years. We first give an extensive history of LISP, particularly of the MACLISP branch, in order to explain in context the motivation for COMMON LISP. We enumerate the goals and non-goals of the language design, discuss the language features of primary interest, and then consider how these features help to meet the expressed goals. Finally, the status (as of May 1982) of six implementations of COMMON LISP is summarized.
Cloning of a Novel Apaf-1-Interacting Protein: A Potent Suppressor of Apoptosis and Ischemic Neuronal Cell Death

Cytochrome c-initiated activation of apoptotic protease activating factor-1 (Apaf-1) is a key step in the mitochondrial-signaling pathway for the activation of death-executing caspases in apoptosis. This signaling pathway has been implicated in the pathophysiology of various neurological disorders, including ischemic brain injury. In this study, we have cloned a novel rat gene product, designated as Apaf-1-interacting protein (AIP), which functions as a dominant-negative inhibitor of the Apaf-1-caspase-9 pathway. AIP is constitutively expressed in the brain, but at substantially lower levels than Apaf-1 and caspase-9. AIP can directly bind to Apaf-1 in vitro through its N-terminal caspase-recruiting domain, and this protein interaction was increased in cells undergoing apoptosis. Cytosolic extracts from cells overexpressing AIP were highly resistant to cytochrome c- dATP-induced activation of caspase-9 and caspase-3. Gene transfection of AIP into cell lines, including the neuronal-differentiated PC12 cells, potently suppressed apoptosis induced by various pro-apoptotic stimuli. To further investigate the functional role of AIP in primary neurons and in the brain, an adeno-associated virus (AAV) vector carrying the AIP cDNA was constructed. AAV-mediated overexpression of AIP in primary cortical- hippocampal neurons markedly reduced cell death and caspase-3 activation triggered by protein kinase C inhibition, DNA damage, or oxygen- glucose deprivation. Moreover, intracerebral infusion of the AAV vector resulted in robust AIP expression in the hippocampus and significantly promoted CA1 neuronal survival after transient global cerebral ischemia. These results suggest that molecular targeting of the Apaf-1-caspase-9 signaling pathway may be a feasible neuroprotective strategy to enhance the endogenous threshold for caspase activation and prevent neuronal loss in stroke and related disorders.
PHAROS - Personalizing Users' Experience in Audio-Visual Online Spaces

The large volume of user generated content, although sometimes amateurish, represents a valuable source of information for audiovisual service providers. For example, companies and organizations can efficiently get feedback from consumers observing their online interaction with social media providers. Offering accurately personalized services is possible now, since users provide more personal information about themselves openly, which was previously much more difficult to perceive and measure. In PHAROS, we aim at exploiting the new and freely available data to improve users’ online experience with respect to their interaction with new media. We focus on building technologies, which bridge the gap between the availability of information (both in form of descriptions of content, such as annotations, and user interests and preferences) and the use of it, for augmenting traditional search and retrieval methods or for personalization purposes. In this paper, we describe how this external information can be brought into PHAROS and how it is used to support users, also describing the multiple components supporting this process.
