Shared Visualizations In Support of Distributed Creative Communities

The paper is concerned with support for distributed groups of creative knowledge workers: in this case designers. We consider requirements that designers have regarding internalisation and externalisation of ideas and concepts as well as requirements relating to collaboration. We review an online system whose facilities for the graphical representation of data were found to be popular. The evaluation was in the context of a group task and the results, including instances of tacit knowledge sharing, have led us to formulate a number of recommendations as to how such systems might be made still more effective for collaborative working

Web-Based support for creative collaboration

This paper considers web-based systems in support of distributed communities involving creative work. It is concerned with the sharing of knowledge that might otherwise remain unspoken, or tacit, amongst those engaged in design tasks. Drawing on the results of the evaluation of a prototype system, pointers for future systems are presented

Email as co-habitat in distributed organisations

Email has now become so ubiquitous that it has surpassed its early role as an asynchronous communication tool. Having contributed to the rise of the distributed organisation, email is being used in diverse ways and for purposes for which it was not intended. It is no longer a technology of individual habitats, but one where members of distributed organisations co-habit. This paper charts the study of email management, from early investigations of personal approaches to handling email overload, through to a review of software applications designed to ameliorate this. It suggests that while email has been appropriated for information and knowledge management, there has been minimal analysis of this beyond the individual. Therefore, it presents a case study of a distributed organisation, detailing the process by which email was leveraged for organisational knowledge through the design of an application that enabled visualisation of email data

Phylogeny and Biogeography of the Carnivorous Plant Family Sarraceniaceae

The carnivorous plant family Sarraceniaceae comprises three genera of wetland-inhabiting pitcher plants: Darlingtonia in the northwestern United States, Sarracenia in eastern North America, and Heliamphora in northern South America. Hypotheses concerning the biogeographic history leading to this unusual disjunct distribution are controversial, in part because genus- and species-level phylogenies have not been clearly resolved. Here, we present a robust, species-rich phylogeny of Sarraceniaceae based on seven mitochondrial, nuclear, and plastid loci, which we use to illuminate this family's phylogenetic and biogeographic history. The family and genera are monophyletic: Darlingtonia is sister to a clade consisting of Heliamphora+Sarracenia. Within Sarracenia, two clades were strongly supported: one consisting of S. purpurea, its subspecies, and S. rosea; the other consisting of nine species endemic to the southeastern United States. Divergence time estimates revealed that stem group Sarraceniaceae likely originated in South America 44–53 million years ago (Mya) (highest posterior density [HPD] estimate = 47 Mya). By 25–44 (HPD = 35) Mya, crown-group Sarraceniaceae appears to have been widespread across North and South America, and Darlingtonia (western North America) had diverged from Heliamphora+Sarracenia (eastern North America+South America). This disjunction and apparent range contraction is consistent with late Eocene cooling and aridification, which may have severed the continuity of Sarraceniaceae across much of North America. Sarracenia and Heliamphora subsequently diverged in the late Oligocene, 14–32 (HPD = 23) Mya, perhaps when direct overland continuity between North and South America became reduced. Initial diversification of South American Heliamphora began at least 8 Mya, but diversification of Sarracenia was more recent (2–7, HPD = 4 Mya); the bulk of southeastern United States Sarracenia originated co-incident with Pleistocene glaciation, <3 Mya. Overall, these results suggest climatic change at different temporal and spatial scales in part shaped the distribution and diversity of this carnivorous plant clade

International Consensus Statement on Rhinology and Allergy: Rhinosinusitis

Background: The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR‐RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR‐RS‐2021 as well as updates to the original 140 topics. This executive summary consolidates the evidence‐based findings of the document. Methods: ICAR‐RS presents over 180 topics in the forms of evidence‐based reviews with recommendations (EBRRs), evidence‐based reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. Results: ICAR‐RS‐2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence‐based management algorithm is provided. Conclusion: This ICAR‐RS‐2021 executive summary provides a compilation of the evidence‐based recommendations for medical and surgical treatment of the most common forms of RS

Challenges in Prototyping Email in Three Dimensions

There are numerous arguments for the usefulness of paper prototyping. It allows the identification and prevention of design problems and usability issues before work begins on an electronic proof of concept (EPOC). It is less costly and more flexible than testing with an EPOC and then amending it after it has been built. However, this project presented challenges in relation to paper prototyping an application that represents email data threedimensionally. Although it was possible to do some abstract prototyping on paper, there were limitations in the extent to which a 3D model could be articulated two-dimensionally. The paper details the authors multimethodological approach to developing an application which enables the search, display and filtering of email data beyond the standard functionalities available in conventional email software. Such methodologies included persona development, task analysis, competitor analysis, abstract (paper and electronic) prototyping. This combination demonstrates the utility of Houde and Hill s (1997) model of developing a range of prototypes within a single project to demonstrate role, look and feel and implementation of a proposed design
