Exposure Render Web Service
No full textDuring the Bachelor End Project we have been tasked with developing a web portal for the Exposure Render. The Exposure Render is able to interactively visualize volumetric data to photo realistic images. This means that the web portal would allow users to view a visualization of their medical data.The requirements of the web portal have been established through interviews with the client and TU coach. During the process of development an agile methodology was used for the division of tasks and iteratively work towards the end product. From the eight sprints a fully functioning prototype hasbeen developed, which satisfies all the main requirements that had been requested by the client. The prototype is separated into three applications: a web interface for the user, a server for persistent data storage and a container for streaming and controlling the rendered scene by Exposure Render. Theseapplications cooperate to form the requested web portal.<br/
Author contributions to ecological publications: What does it mean to be an author in modern ecological research?
No full textAuthorship is a central element of scientific research carrying a variety of rewards and responsibilities, and while various guidelines exist, actual author contributions are often ambiguous. Inconsistent or limited contributions threaten to devalue authorship as intellectual currency and diminish authors' responsibility for published content. Researchers have assessed author contributions in the medical literature and other research fields, but similar data for the field of ecological research are lacking. Authorship practices in ecological research are broadly representative of a variety of fields due to the cross-disciplinary nature of collaborations in ecological studies. To better understand author contributions to current research, we distributed a survey regarding co-author contributions to a random selection of 996 lead authors of manuscripts published in ecological journals in 2010. We obtained useable responses from 45% of surveyed authors. Reported lead author contributions in ecological research studies consistently included conception of the project idea, data collection, analysis, and writing. Middle and last author contributions instead showed a high level of individual variability. Lead authorship in ecology is well defined while secondary authorship is more ambiguous. Nearly half (48%) of all studies included in our survey had some level of non-compliance with Ecological Society of America (ESA) authorship guidelines and the majority of studies (78%) contained at least one co-author that did not meet International Committee of Medical Journal Editors (ICMJE) requirements. Incidence of non-compliance varied with lead author occupation and author position. The probability of a study including an author that was non-compliant with ESA guidelines was lowest for professor-led studies and highest for graduate student and post doctoral researcher-led studies. Among studies with > two co-authors, all lead authors met ESA guidelines and only 2% failed to meet ICMJE requirements. Middle (24% ESA, 63% ICMJE) and last (37% ESA, 60% ICMJE) authors had higher rates of non-compliance. The probability of a study containing a co-author that did not meet ESA or ICMJE requirements increased significantly with the number of co-authors per study although even studies with only two co-authors had a high probability of non-compliance of approximately 60% (ICMJE) and 15 to 40% (ESA). Given the variable and often limited contributions of authors in our survey and past studies of other research disciplines, institutions, journals, and scientific societies need to implement new approaches to instill meaning in authorship status. A byline approach may not alter author contributions but would better define individual contributions and reduce existing ambiguity regarding the meaning of authorship in modern ecological research
Author self-citation in the general medicine literature.
No full textAuthor self-citation contributes to the overall citation count of an article and the impact factor of the journal in which it appears. Little is known, however, about the extent of self-citation in the general clinical medicine literature. The objective of this study was to determine the extent and temporal pattern of author self-citation and the article characteristics associated with author self-citation.We performed a retrospective cohort study of articles published in three high impact general medical journals (JAMA, Lancet, and New England Journal of Medicine) between October 1, 1999 and March 31, 2000. We retrieved the number and percentage of author self-citations received by the article since publication, as of June 2008, from the Scopus citation database. Several article characteristics were extracted by two blinded, independent reviewers for each article in the cohort and analyzed in multivariable linear regression analyses. Since publication, author self-citations accounted for 6.5% (95% confidence interval 6.3-6.7%) of all citations received by the 328 articles in our sample. Self-citation peaked in 2002, declining annually thereafter. Studies with more authors, in cardiovascular medicine or infectious disease, and with smaller sample size were associated with more author self-citations and higher percentage of author self-citation (all p≤0.01).Approximately 1 in 15 citations of articles in high-profile general medicine journals are author self-citations. Self-citation peaks within about 2 years of publication and disproportionately affects impact factor. Studies most vulnerable to this effect are those with more authors, small sample size, and in cardiovascular medicine or infectious disease

Oriental enlightenment: the problematic military experiences and cultural claims of Count Maurice Auguste comte de Benyowsky in Formosa during 1771
No full textMaurice Benyowsky's colourful version of his global adventures during the heady, expansive days of the late-Enlightenment remains still as an historical account, and is perhaps destined for reification at a time of romantic, postmodernist cultural affirmation. Yet this paper argues that within it there lies a virile and possibly dangerous Orientalism, one at least partially based upon a lurid, opportunistic and self-seeking fabrication of his visit to Taiwan (Formosa) in the year 1771. This paper examines the veracity, provenance and historiography of the Benyowsky account of late-eighteenth century Formosa, both as an exercise in one facet of Taiwanese history and as some exploration of the origin and maintenance of European views of the "other" and of the "orient" as they were transforming during the late-Enlightenment period. Furthermore a principal task is to provide an historiographical analysis that illustrates both the initial reasons for the acceptance of Benyowsky's lurid account as well as the wider contexts of its long life as a seemingly reliable and authentic tale. Questions remain as to the cultural contexts of any general acceptance of otherwise doubtful stories, experiments, claims and "adventures". Here there is little doubt that the original Memoirs were given greater credence by Benyowsky's talent in self-fashioning his character and status as those of a reliable gentleman

Mining author relationship in scholarly networks based on tripartite citation analysis.
No full textFollowing scholars in Scientometrics as examples, we develop five author relationship networks, namely, co-authorship, author co-citation (AC), author bibliographic coupling (ABC), author direct citation (ADC), and author keyword coupling (AKC). The time frame of data sets is divided into two periods: before 2011 (i.e., T1) and after 2011 (i.e., T2). Through quadratic assignment procedure analysis, we found that some authors have ABC or AC relationships (i.e., potential communication relationship, PCR) but do not have actual collaborations or direct citations (i.e., actual communication relationship, ACR) among them. In addition, we noticed that PCR and AKC are highly correlated and that the old PCR and the new ACR are correlated and consistent. Such facts indicate that PCR tends to produce academic exchanges based on similar themes, and ABC bears more advantages in predicting potential relations. Based on tripartite citation analysis, including AC, ABC, and ADC, we also present an author-relation mining process. Such process can be used to detect deep and potential author relationships. We analyze the prediction capacity by comparing between the T1 and T2 periods, which demonstrate that relation mining can be complementary in identifying authors based on similar themes and discovering more potential collaborations and academic communities
Author Credit for Transdisciplinary Collaboration.
No full textTransdisciplinary collaboration is the key for innovation. An evaluation mechanism is necessary to ensure that academic credit for this costly process can be allocated fairly among coauthors. This paper proposes a set of quantitative measures (e.g., t_credit and t_index) to reflect authors' transdisciplinary contributions to publications. These measures are based on paper-topic probability distributions and author-topic probability distributions. We conduct an empirical analysis of the information retrieval domain which demonstrates that these measures effectively improve the results of harmonic_credit and h_index measures by taking into account the transdisciplinary contributions of authors. The definitions of t_credit and t_index provide a fair and effective way for research organizations to assign credit to authors of transdisciplinary publications
Principles of regulatory policy design
Get PDFThe author contrasts command-and-control regulation (tight control of water purification, for example) with more flexible forms, including incentive regulation (such as price cap regulation), potential regulation (providing for closer scrutiny if enough customers complain), and reactive rather than proactive policies (the firm proposing actions, the regulatory saying yes or no). He contrasts informing regulation (for example, requiring that consumers be informed about ingredients in a product) and enforcing regulation (for example, prohibiting the use of certain chemicals in foods). A country's institutional structure can limit the regulators'potential for commitment, he says -- especially if regulators are limited in their ability to deliver rewards or penalties. The scope and function of regulation may also be fairly limited when technological conditions allow competition to discipline producers. Sophisticated buyers with economic power may reduce the need for regulatory control, and rapid technological change can render comprehensive command-and-control regulation ineffective or debilitating. Many forces operate simultaneously, making regulatory design a complex undertaking. Inertia is one such influence. Regulatory policies that once served an important purpose sometimes persist even though they no longer serve that purpose -- sometimes because they favor a constituency that convinces the regulator to keep the control in place. Subsidies and tariff protection often continue long past the time needed to promote the development of an infant industry, for example. When there is limited public outcry against continuing the special treatment, and the affected firms strongly urge its continuance, the regulator may be convinced to continue special treatment that no longer serves the public interest. Regulation may also be affected by the regulators'personal ambition. When regulators are"captured"by regulated firms -- diverted from the goal of protecting consumers through the promise of personal rewards for favorable treatment of the firms -- regulation may not serve society's best interest. Even if regulators are not motivated by self-interest, their ideas of what is best for society may differ from those of other government officials or of society at large. When that happens, which goals are pursued depends largely on the autonomy regulators that are granted and on the balance of power among government bodies.Regulation should be viewed in this large context to be understood fully.Administrative&Regulatory Law,Environmental Economics&Policies,National Governance,Economic Theory&Research,Insurance&Risk Mitigation
