    Concern for Information Privacy and Online Consumer Purchasing

    Although electronic commerce experts often cite privacy concerns as barriers to consumer electronic commerce, there is a lack of understanding about how these privacy concerns impact consumers\u27 willingness to conduct transactions online. Therefore, the goal of this study is to extend previous models of e-commerce adoption by specifically assessing the impact that consumers\u27 concerns for information privacy (CFIP) have on their willingness to engage in online transactions. To investigate this, we conducted surveys focusing on consumers\u27 willingness to transact with a well-known and less well-known Web merchant. Results of the study indicate that concern for information privacy affects risk perceptions, trust, and willingness to transact for a well-known merchant, but not for a less well-known merchant. In addition, the results indicate that merchant familiarity does not moderate the relationship between CFIP and risk perceptions or CFIP and trust. Implications for researchers and practitioners are discussed

    Does Trust Reduce Concern for Information Privacy in E-Commerce?

    Internet commerce continues to grow rapidly and is expected to exceed $5 trillion in 2005. Nevertheless concern for information privacy has been identified as a major consideration constraining many from internet consumerism. Trust has also been identified as an antecedent to willingness/intent to transact, buy or purchase. This research seeks to specify and support a model that involves additional constructs such as familiarity, risk, quality of website, gender, peresonal innovativeness, discretionary income, age, and other factors in order to identify what factors and/or interactions are significant in determining whether a prospect intends to part with funds and become a customer. Data to be gathered with online survey and analyzed using regression

    This paper summarizes the results of a panel discussion offering advice to doctoral students in advancing through their programs and getting a start on their career. The panel was held at the 2003 Annual Conference of the Southern Association for Information Systems, and panelists included five senior MIS faculty members who, combined, have chaired over 80 dissertations. Topics included choosing a dissertation topic, dealing with the dissertation committee, completing the dissertation, the job hunt, marketability, building a publication record, and advice for new faculty

    The Bicarbonate Transporter Is Essential for Bacillus anthracis Lethality

    In the pathogenic bacterium Bacillus anthracis, virulence requires induced expression of the anthrax toxin and capsule genes. Elevated CO2/bicarbonate levels, an indicator of the host environment, provide a signal ex vivo to increase expression of virulence factors, but the mechanism underlying induction and its relevance in vivo are unknown. We identified a previously uncharacterized ABC transporter (BAS2714-12) similar to bicarbonate transporters in photosynthetic cyanobacteria, which is essential to the bicarbonate induction of virulence gene expression. Deletion of the genes for the transporter abolished induction of toxin gene expression and strongly decreased the rate of bicarbonate uptake ex vivo, demonstrating that the BAS2714-12 locus encodes a bicarbonate ABC transporter. The bicarbonate transporter deletion strain was avirulent in the A/J mouse model of infection. Carbonic anhydrase inhibitors, which prevent the interconversion of CO2 and bicarbonate, significantly affected toxin expression only in the absence of bicarbonate or the bicarbonate transporter, suggesting that carbonic anhydrase activity is not essential to virulence factor induction and that bicarbonate, and not CO2, is the signal essential for virulence induction. The identification of this novel bicarbonate transporter essential to virulence of B. anthracis may be of relevance to other pathogens, such as Streptococcus pyogenes, Escherichia coli, Borrelia burgdorferi, and Vibrio cholera that regulate virulence factor expression in response to CO2/bicarbonate, and suggests it may be a target for antibacterial intervention

    Alliance of Genome Resources Portal: unified model organism research platform

    Get PDF
    The Alliance of Genome Resources (Alliance) is a consortium of the major model organism databases and the Gene Ontology that is guided by the vision of facilitating exploration of related genes in human and well-studied model organisms by providing a highly integrated and comprehensive platform that enables researchers to leverage the extensive body of genetic and genomic studies in these organisms. Initiated in 2016, the Alliance is building a central portal (www.alliancegenome.org) for access to data for the primary model organisms along with gene ontology data and human data. All data types represented in the Alliance portal (e.g. genomic data and phenotype descriptions) have common data models and workflows for curation. All data are open and freely available via a variety of mechanisms. Long-term plans for the Alliance project include a focus on coverage of additional model organisms including those without dedicated curation communities, and the inclusion of new data types with a particular focus on providing data and tools for the non-model-organism researcher that support enhanced discovery about human health and disease. Here we review current progress and present immediate plans for this new bioinformatics resource

    Assessment of age-related changes in pediatric gastrointestinal solubility

    PurposeCompound solubility serves as a surrogate indicator of oral biopharmaceutical performance. Between infancy and adulthood, marked compositional changes in gastrointestinal (GI) fluids occur. This study serves to assess how developmental changes in GI fluid composition affects compound solubility.MethodsSolubility assessments were conducted in vitro using biorelevant media reflective of age-specific pediatric cohorts (i.e., neonates and infants). Previously published adult media (i.e., FaSSGF, FeSSGF, FaSSIF.v2, and FeSSIF.v2) were employed as references for pediatric media development. Investigations assessing age-specific changes in GI fluid parameters (i.e., pepsin, bile acids, pH, osmolality, etc.) were collected from the literature and served to define the composition of neonatal and infant media. Solubility assessments at 37Β°C were conducted for seven BCS Class II compounds within the developed pediatric and reference adult media.ResultsFor six of the seven compounds investigated, solubility fell outside an 80–125% range from adult values in at least one of the developed pediatric media. This result indicates a potential for age-related alterations in oral drug performance, especially for compounds whose absorption is delimited by solubility (i.e., BCS Class II).ConclusionDevelopmental changes in GI fluid composition can result in relevant discrepancies in luminal compound solubility between children and adults.<br/

    Investigating Implicit Aspects of Virtue: Understanding Humility Among Moral Exemplars

    No full text
    Our research project will investigate the virtue of humility among real world humanitarian exemplars, such as holocaust rescuers and hospice workers. We will use computer technology to analyze interviews with these types of populations to understand the different factors involved in the virtue of humility. Following the work of Aristotle, we believe this virtue is formed as a kind of habit that becomes a natural extension of one’s character. We aim to operationalize and empirically evaluate aspects of the virtue of humility through the computational analysis of implicit semantic processing embedded in the narratives of real world humanitarians. Latent semantic analysis, multi-dimensional scaling, and hierarchical cluster analysis will be used to map self-understanding schemas in these populations and its role in humility while serving others.N
