A flexible layout model for a web-based adaptive hypermedia architecture
No full textThe paper presents an attempt to extend a general-purpose adaptive hypermedia (AH)
architecture AHA! with flexible and rich interface by re-using some ideas explored in a more
specific AH system InterBook. The most popular application (course) created with the old
version of AHA! (the hypermedia course 2L670, later called 2L690, at the TU/e) used a
single-window/single-frame concept representation which had advantages of its simplicity and
clarity for the user. In this course concepts are always represented in a single frameless
window. This mechanism is not sophisticated enough to serve as a general-purpose
mechanism for concept representation. InterBook on the other hand has a much richer user
interface characterized by the use of multiple windows and frames. This approach has more
possibilities for representing the course domain, but has a problem of its rigid presentation
structire. The author has no possibilities of adapting the user interface to the specific course
which means that every course served by Interbook has the same look independent of the
course characteristics. To address the lack of user interface possibilities in AHA! we
developed the Layout model that employs the strong points of Interbook user interface. The
dynamic structures of the Layout model are easily extendible and give author the power to
adapt the user interface to the nature of the course
Bruikbaarheid BRA-gegevens voor analyse dienstuitvoeringen: Samenwerkingsprojekt GVU-LVV
No full textRapport in opdracht van GVU Utrecht. In fase B van het samenwerkingsprojekt "kwaliteitsbeheersing kollektief openbaar vervoer" van het GVU en LVV moet nagegaan worden of de aktuele operationele kwaliteit voldoet aan de gewenste c.q. aan te bieden kwaliteit. Voorafgaande hieraan diende echter eerst de bruikbaarheid te worden vastgesteld van de door het GVIT verzamelde BRA-gegevens voor het bepalen van de operationele kwaliteit van de dienstuitvoering. Hiertoe heeft het LVV een voorbeelddataset onderzocht en getracht deze zodanig te converteren dat verwerking mogelijk is met het programma TRITAPT. TRITAPT (trip time analysis in public transport) is een programma ontwikkeld door het LVV, dat inzicht geeft in de aktuele operationele kwaliteit van dienstuitvoeringen in temen van snelheid, stiptheid en regelmaat. Uit dit onderzoek volgde dat door verschillen in definities van de operationele processen (rijtijd, halteertijd en verliestljd) en de wijze van verzamelen van gegevens, verwerken van de BRA-gegevens niet zonder meer mogelijk is. Er bleek een aanpassing van het TRITAPT programma noodzakelijk. Na de benodigde aanpassing van TRITAPT is nagegaan welke resultaten de analyse van de beschikbare gegevens leverde. Een aantal uitkomsten bleken hierbij een nadere beschouwing te vragen en een verdere aanpassing van TRITAPT. Naar verwachting levert dit echter geen onoverkomelijke problemen op. De conclusie is dan ook, dat in fase B de BRA-gegevens bruikbaar zijn voor de analyse van dienstuitvoeringen.Transport and PlanningCivil Engineering and Geoscience
Supporting user adaptation in adaptive hypermedia applications
No full textA hypermedia application offers its users a lot of freedom to navigate through a large hyperspace. The rich link structure of the hypermedia application can not only cause users to get lost in the hyperspace, but can also lead to comprehension problems because different users may be interested in different pieces of information or a different level of detail or difficulty. Adaptive hypermedia systems (or AHS for short) aim at overcoming these problems by providing adaptive navigation support and adaptive content. The adaptation is based on a user model that represents relevant aspects about the user. At the Eindhoven University of Technology we developed anAHS, named AHA {DC981. To describe its functionality and that of future adaptive systems we also developed a reference model for the architecture of adaptive hypermedia applications, named AHAM (for Adaptive Hypermedia Application Model) {DHW991. In AHAM knowledge is represented through hierarchies of large composite abstract concepts as well as small atomic ones. AHAM also divides the different aspects of an AHS into a domain model (DM). a user model (UM) and an adaptation model (AM). This division provides a clear separation of concerns when developing an adaptive hypermedia application. In this paper, we concentrate on the user modeling aspects of AHAM, but also describe how they relate to the domain model and the adaptation model. Also. we provide a separation between the adaptation rules an author or system designer writes (as part of the adaptation model) and the system's task of executing these rules in the right order. This distinction leads to a simplification of the author's or system designer's task to write adaptation rules. We illustrate authoring and adaptation in by some examples in the AHS AHA

AHA! meets Interbook, and more...
No full textThe AHA! system (De Bra & Calvi, 1998, De Bra et al, 2002) has been repeatedly extended over the past few years, focusing on adaptation flexibility. This has resulted in a powerful adaptation engine, but little support for creating adaptive applications. AHA! provides tools for defining the conceptual structure and the adaptation of an application, but leaves the presentation and additional support tools up to the author of that application. Interbook (Brusilovsky et al, 1998) on the other hand is a simple environment for creating and serving adaptive textbooks, with a rich user interface characterized by the use of multiple windows and frames. Authors write an annotated Microsoft Word file, which is translated to a series of files used by Interbook. This paper presents an extension of AHA! that enables a high-level specification of the presentation (layout) of an AHA! application. We illustrate this extension through a powerful demonstrator: an Interbook to AHA! compiler. The source format for Interbook is translated to AHA! with the new Layout model. The dynamic structures of the Layout model are easily extendible and give author the power to adapt the user interface to the nature of the application. AHA! can thus "emulate" not just Interbook but other adaptive environments as well

Description of nymph. General color dark yellow to ochraceous. Head dark yellow, lighter around eyes and ocelli, below post-frontal line and on frontoclypeal region, two small lighter spots above M-line; compound eyes black; ocelli with a translucent layer; post-frontal line in some specimens exceeding ocelli (Fig. 1A). Antennae light yellow. Clypeus dark yellow to yellow. Labrum yellow to light yellow; maxillae light yellow with lacinia yellow and galea light yellow; mandible light yellow to dark brown, with brown band in ventral base margin, 5 pointed teeth on distal margin, mostly decreasing in size toward base, but teeth 2 and 4 similar in size (Figs. 2A, 2B and 2C). Pronotum rectangular, with a dark brown band in the margin of pronotum, lateral band wide (Fig. 1A). Pronotum, mesonotum, and metanotum with brown areas and yellowish spots forming a characteristic color pattern; presence of small bristles. Thoracic filamentous gills present (Fig. 1B): ASC [1], PSC [1, 2, 3], AT [2, 3], PT [3]. Legs light yellow (Fig. 2D). Prothoracic leg raptorial. In anterior view, longitudinal row of long and thin pilosity in the extremities of femora and tibia, numerous sparse short spine-like bristles covering all the surface of femora and tibia. In posterior view, these bristles when present restricted only to the margin areas of femora. In anterior and posterior views, presence of spines in the extremities of femora and tibia. Abdomen dark yellow (Fig. 1C); spines covering margin of each segment. Anal gills present. Cerci light yellow (Fig. 2E), with long bristles and short spine-like setae in each segment. Measurements. Female forewing length: 13.9– 16.1 mm, n= 27. Male forewing length: 11.9– 14.5 mm, n= 20. Nymphs head width: 2.6– 2.8 mm; head length: 1.6– 1.7 mm; pronotum width: 2.9– 3.1 mm; pronotum length: 1.25– 1.5 mm; wing pads width: 1.7– 2.1 mm; wing pads length: 1.5– 1.8 mm; total body length (without cerci) 9.7– 12.1 mm; n= 6. Remarks. Adult specimens examined during this study (Fig. 3A) agree with the description of Bispo & Neves (2005). However, the forewing length of some males were smaller than previously reported. Additionally, the ventral cavity of the penial armature of M. matogrossensis is wider in our males, narrower in the original description, resembling the penial armature of M. pulchra Ribeiro & Froehlich, 1999. Despite this difference, we have confidently determined our specimens as M. matogrossensis considering the above variation as intraspecific. Additionally, the nymph resembles M. delicata Ribeiro-Ferreira & Froehlich, 1999 in general color and pronotal shape (Ferreira-Ribeiro & Gorayeb 2016). However, nymphs of M. delicata have the following configuration of gills: ASC [1, 2, 3], PSC [1, 2, 3], AT [2, 3], a pattern different from the one found in M. matogrossensis. Nymphs of M. matogrossensis were collected from pristine streams with frequent riffle areas with fast current. In these streams, substrate varied with submerged logs, roots, leaf packs, macrophytes, rocks, and gravel. A portion of the Cachoeira do Evilson (Evilson’s waterfall) is well preserved, despite some spots in pasture. The surrounding streams have been relatively little impacted. The other collecting sites are well-preserved. Bispo & Neves (2005) described M. matogrossensis from the Municipality of Jaciara, in Mato Grosso State, Brazil. No other records for this species are known. We present first records of the genus and the species for Tocantins State, approximately 1000 km from the type locality of M. matogrossensis. Both sites are characterized by areas being mainly covered by Cerrado.Published as part of Rippel, Mellis Layra Soares, Novaes, Marcos Carneiro & Krolow, Tiago Kütter, 2019, First records of Kempnyia and Macrogynoplax (Plecoptera: Perlidae) from Tocantins State, Brazil with description of the immatures and the adult female, pp. 471-478 in Zootaxa 4700 (4) on pages 472-473, DOI: 10.11646/zootaxa.4700.4.5, http://zenodo.org/record/355759
A Circular Business Model for a Pregnancy Bra
No full textThis report proposes a strategy to develop a circular business model for Feelou, a company that has worked on a sustainable pregnancy bra. The circular business model aims to improve the lifespan of the bra and reduce resource usage. This report consists of a research phase and a conceptualisation phase. The research phase explores the current industry and the challenges for the resource flows in the circular business model. The conceptualisation phase aims to solve the challenges that are found in the research phase, resulting in a roadmap for development of a circular business model.The main challenges for a sustainable company in the current clothing industry are competing with greenwashing companies and finding sustainable alternatives for currently common practices, as the industry is a long way from becoming sustainable. Three paradoxes describe the dilemmas that Feelou faces in launching a circular business model for their bra.Firstly, the Business model paradox shows that a sales model would be easier for Feelou and the customer. However, it would be less sustainable than a lease model, in which Feelou would keep ownership of the product. Secondly, the Perceived hygiene paradox is an important challenge for the reuse of bras: many women find pre-loved bras unappealing, however this is influenced by familiarity with the previous owner. Finally, the Circular impact paradox considers the scale versus quality of impact. Doing it perfectly mostly means doing it on a smaller scale, which affects overall impact. To grow, concessions need to be made.The Butterfly Diagram (Ellen MacArthur Foundation, 2013) inspired the Resource flow diagram (RFD), a model that was used to explore possibilities for a circular business model. The analysis showed that Feelou should focus on the inner loops as this is where Feelou has a direct influence. The main challenge in the inner loops lies in the Perceived hygiene paradox. As a lease model creates many additional challenges, a sales model is pursued in the conceptualisation phase.The conceptualisation phase started with a co-creation session with the target group. Many solutions were provided by the participants, noteworthy findings include: accompanying the product by a letter that describes the ideal life cycle of the bra, emphasising the value of sustainable behaviour as the reward itself and a focus on positive communication. The RFD exploration and brainstorm provided enough material to fill in the service blueprint, providing an overview of the circular business model and its components. An interesting insight of the service blueprint is that Feelou can inspire customers to treat the bra sustainably on three different moments: during sale, during use and after use. The business model canvas provided insight into the main challenge for the selection of the target group and value proposition: the dual focus on comfort and sustainability in the branding of Feelou. Further exploration through the brand DNA shows that this dual focus actually provides a competitive advantage. The comfort aspect focuses on the individual, while the sustainability aspect focuses on society and the planet, resulting in a branding strategy that is more resilient than comfort or sustainability alone would be.The final deliverable, a roadmap helps to put all ideas and sides of the circular business model into perspective over time. It splits the development into the startup phase, the scale up phase and finally the ideal model. It provides a toolbox of resources that can be used to set up the circular business model and let it grow towards the next phase.Strategic Product Desig
Bras are not for burning: the bra and young urban women in Delhi and Bombay
No full textScholars have analysed the meanings of western outer-clothes worn by women in India, however these studies seldom discuss the semi-hidden bra. Whereas the panty through the ‘Pink Chaddis’ campaign has been used as a symbolic tool of female power and resistance in India, the power meanings of the bra remain ambiguous. Bras have not been discussed as symbolic markers of female empowerment like chaddis, nor can be assumed objects of male oppression as in the history of western feminism.This chapter explores the bra and its proximity to young (18–24 year old) urban Indian women’s bodies; the ambiguity of its hidden yet publicly viewed nature which discloses tensions of the sexualised female body and changing ideals of Indian femininities that outer western garments cannot always reveal. I discuss how the bra lends insight into Indian women’s bodies as paradoxical spaces of public and private power as India begins to rapidly urbanise. A power-play between that of an increase in the moral policing of urban Indian women’s sartorial identities and the emerging bi-cultural youth identities resisting these moral codes of dressing.Taken from a qualitative study between 2010–2014, the author discusses how the bra in India centres on the discourse of shame and the anxieties of western modernity recycled from the Indian independence movement. Author reveals how patriarchal codes of shame are questioned by the symbolic meanings of power that young urban Indian women attach to their bras
A POLISH BRA OBSESSED WOMEN COMMUNITY AS A DISCOURSE COMMUNITY
No full textThe article addresses a female virtual community consisting of enthusiasts of bra fitting and connoisseurs of beautiful, especially well-chosen, lingerie, mainly bras. The members of this community sometimes are called in Polish “stanikomaniaczki” (which can be translated into bra maniacs, bra obsessed women) or lobbystki (which means lobbyists). The aim of this article is to consider whether the bra obsessed women community meets the criteria for a discourse community proposed by John Swales (among others in his book entitled Genre Analysis: English in Academic and Research Settings, published in 1990). According to J. Swales, a community is a discourse community if its members: 1. have common goals; 2. use the specific mechanisms and means of internal communication; 3. use these mechanisms and means to obtain information or opinions and to share their knowledge or achievements with other members of the community; 4. communicate with each other using specific types of genres; 5. use a specific vocabulary; 6. have different levels of competence in transmitting and receiving messages, which gives individual members the status of "experts" or "novices". The author is also considering whether all online communities (using similar genres) focused on the exchange of information on a specific topic related to their interests that resulted in creating discourse communities
