Design process excludes users : the co-creation activities between user and designer

User needs are a fundamental element of design. If the design process does not properly reflect user needs, the design will be severely compromised. Therefore, it is worthwhile to investigate how the user is, and user needs are, understood in the design process. In this article, three accepted linear process models for web site and interactive media design are reviewed in terms of the designer and user participation. The article then proposes a user-evolving collaborative design process which is built on co-creation activities between designer and user. Co-creation activities across the entire design process structurally and ontologically reposition the users, and user needs, centrally, which allows the designers to holistically approach to the user needs through building a partnership with the users. Co-creation creates an equal evolving participatory process between user and designer towards sharing values and knowledge and creating new domains of collective creativity.

Extending Web Modeling Language to exploit stigmergy : intentionally recording unintentional trails

Software development and Web site development techniques have evolved significantly over the past 20 years. The relatively young Web Application development area has borrowed heavily from traditional software development methodologies primarily due to the similarities in areas of data persistence and User Interface (UI) design. Recent developments in this area propose a new Web Modeling Language (WebML) to facilitate the nuances specific to Web development. WebML is one of a number of implementations designed to enable modeling of web site interaction flows while being extendable to accommodate new features in Web site development into the future. Our research aims to extend WebML with a focus on stigmergy which is a biological term originally used to describe coordination between insects. We see design features in existing Web sites that mimic stigmergic mechanisms as part of the UI. We believe that we can synthesize and embed stigmergy in Web 2.0 sites. This paper focuses on the sub-topic of site UI design and stigmergic mechanism designs required to achieve this.

Stigmergy within web modelling languages : positive feedback mechanisms

Stigmergy is a biological term originally used when discussing insect or swarm behaviour, and describes a model supporting environment-based communication separating artefacts from agents. This phenomenon is demonstrated in the behavior of ants and their food foraging supported by pheromone trails, or similarly termites and their termite nest building process. What is interesting with this mechanism is that highly organized societies are formed without an apparent central management function. We see design features in Web sites that mimic stigmergic mechanisms as part of the User Interface and we have created generalizations of these patterns. Software development and Web site development techniques have evolved significantly over the past 20 years. Recent progress in this area proposes languages to model web applications to facilitate the nuances specific to these developments. These modeling languages provide a suitable framework for building reusable components encapsulating our design patterns of stigmergy. We hypothesize that incorporating stigmergy as a separate feature of a site’s primary function will ultimately lead to enhanced user coordination.

Living City 2013 Workshop

Living City 2013 Workshop, as part of a school term’s design-based curriculum connected to the KGSC/QUT Design Excellence Program and run from 11 February – 1 May, 2013, was essentially a three-day place-based urban design immersion workshop program for 25 Year 11 Visual Art and Design Students and 2 Teachers from Kelvin Grove State College (KGSC) held at both Queensland University of Technology (QUT) Gardens Point Campus and The Edge, State Library of Queensland. Mentored by 4 design professionals, 2 tertiary design academics, 2 public artists, and 12 QUT tertiary design students, the workshop explored youth-inspired public space design solutions for the active Brisbane City Council redevelopment site of Queens Wharf Road precinct. As well as the face-to-face workshops, for Living City 2013, an interactive web environment was introduced to enable students to connect with each other and program mentors throughout the course of the program. The workshop, framed within notions of ecological, economic, social and cultural sustainability, aimed to raise awareness of the layered complexity and perspectives involved in the design of shared city spaces and to encourage young people to voice their own concerns as future citizens about the shape and direction of their city. The program commenced with an introductory student briefing by stakeholders and mentors at KGSC on 11 February, an introduction to site appraisal and site visit held at QUT and Queens Wharf Road on 20 February, and a follow up site analysis session on 6 March. Day 1 Workshop on April 17 at the Edge, State Library of Queensland, as part of the Design Minds partnership (http://designminds.org.au/kelvin-grove-state-college-excellence-in-art-design/), focused on mentoring team development of a concept design for a range of selected sites. Two workshops on April 22 and 23 at QUT, to develop these designs and presentation schemes, followed this. The workshop program culminated in a visual presentation of concept design ideas and discussion with a public audience in the Ideas Gallery on The Deck, King George Square during the Brisbane City Council City Centre Master Plan Ideas Fiesta on 1 May, 2013, as referenced in the Ideas Fiesta Wrap-up Report (http://www.brisbane.qld.gov.au/planning-building/planning-guidelines-tools/city-centre-master-plan/city-centre-master-plan-ideas-fiesta). Students were introduced to design methodology, team thinking strategies, the scope of design practices and professions, presentation skills and post-secondary pathways, while participating teachers acquired content and design learning strategies transferable in many other contexts. The program was fully documented on the Living City website (http://www.livingcity.net.au/LC2013x/index.html) and has been recognised by the Brisbane City Council Youth Strategy 2014-2019 as a best practice model for making Brisbane a well-designed, subtropical city.

Web mediated market interactions and enterprise software

With increased consolidation and a few large vendors dominating the market, how can software vendors distinguish themselves in order to maintain profitability and gain market share? Increasingly customers are becoming more proactive in selecting a vendor and a product, drawing upon various publications, market surveys, mailing lists, and, of course, other users. In particular, though, a company's Web site is the obvious place to begin information gathering. In sum, it may seem that the days of the uninformed customer prepared to be "sold to" are potentially all but gone.

Going live : building academic capacity in blended learning using web-conferencing technologies

This paper reports on a current initiative at Queensland University of Technology to provide timely, flexible and sustainable training and support to academic staff in blended learning and associated techno-pedagogies via a web-conferencing classroom and collaboration tool, Elluminate Live!. This technology was first introduced to QUT in 2008 as part of the university‘s ongoing commitment to meeting the learning needs of diverse student cohorts. The centralised Learning Design team, in collaboration with the university‘s department of eLearning Services, was given the task of providing training and support to academic staff in the effective use of the technology for teaching and learning, as part of the team‘s ongoing brief to support and enhance the provision of blended learning throughout the university. The resulting program, ―Learning Design Live‖ (LDL) is informed by Rogers‘ theory of innovation and diffusion (2003) and structured according to Wilson‘s framework for faculty development (2007). This paper discusses the program‘s design and structure, considers the program‘s impact on academic capacity in blended learning within the institution, and reflects on future directions for the program and emerging insights into blended learning and participant engagement for both staff and students.

EVpedia: A community web portal for extracellular vesicles research

Motivation Extracellular vesicles (EVs) are spherical bilayered proteolipids, harboring various bioactive molecules. Due to the complexity of the vesicular nomenclatures and components, online searches for EV-related publications and vesicular components are currently challenging. Results We present an improved version of EVpedia, a public database for EVs research. This community web portal contains a database of publications and vesicular components, identification of orthologous vesicular components, bioinformatic tools and a personalized function. EVpedia includes 6879 publications, 172 080 vesicular components from 263 high-throughput datasets, and has been accessed more than 65 000 times from more than 750 cities. In addition, about 350 members from 73 international research groups have participated in developing EVpedia. This free web-based database might serve as a useful resource to stimulate the emerging field of EV research. Availability and implementation The web site was implemented in PHP, Java, MySQL and Apache, and is freely available at http://evpedia.info.

An Optimal Mechanism for Sponsored Search Auctions on the Web and Comparison With Other Mechanisms

In this paper, we first describe a framework to model the sponsored search auction on the web as a mechanism design problem. Using this framework, we describe two well-known mechanisms for sponsored search auction-Generalized Second Price (GSP) and Vickrey-Clarke-Groves (VCG). We then derive a new mechanism for sponsored search auction which we call optimal (OPT) mechanism. The OPT mechanism maximizes the search engine's expected revenue, while achieving Bayesian incentive compatibility and individual rationality of the advertisers. We then undertake a detailed comparative study of the mechanisms GSP, VCG, and OPT. We compute and compare the expected revenue earned by the search engine under the three mechanisms when the advertisers are symmetric and some special conditions are satisfied. We also compare the three mechanisms in terms of incentive compatibility, individual rationality, and computational complexity. Note to Practitioners-The advertiser-supported web site is one of the successful business models in the emerging web landscape. When an Internet user enters a keyword (i.e., a search phrase) into a search engine, the user gets back a page with results, containing the links most relevant to the query and also sponsored links, (also called paid advertisement links). When a sponsored link is clicked, the user is directed to the corresponding advertiser's web page. The advertiser pays the search engine in some appropriate manner for sending the user to its web page. Against every search performed by any user on any keyword, the search engine faces the problem of matching a set of advertisers to the sponsored slots. In addition, the search engine also needs to decide on a price to be charged to each advertiser. Due to increasing demands for Internet advertising space, most search engines currently use auction mechanisms for this purpose. These are called sponsored search auctions. A significant percentage of the revenue of Internet giants such as Google, Yahoo!, MSN, etc., comes from sponsored search auctions. In this paper, we study two auction mechanisms, GSP and VCG, which are quite popular in the sponsored auction context, and pursue the objective of designing a mechanism that is superior to these two mechanisms. In particular, we propose a new mechanism which we call the OPT mechanism. This mechanism maximizes the search engine's expected revenue subject to achieving Bayesian incentive compatibility and individual rationality. Bayesian incentive compatibility guarantees that it is optimal for each advertiser to bid his/her true value provided that all other agents also bid their respective true values. Individual rationality ensures that the agents participate voluntarily in the auction since they are assured of gaining a non-negative payoff by doing so.

基于在线模型评估的动态Web系统性能保障

动态多层Web系统在运行时会受到许多不确定性因素的影响.同时,在不同的负载模式下具有不同的性能特性,需要不同的性能模型进行描述.为消除不确定性因素对系统性能的影响,基于反馈控制原理设计的性能保障机制主要采用单一、固定的系统性能模型,对动态Web系统变化的性能特征考虑不够.在负载呈波动且具有不可预测特性的Internet环境中,这会降低性能目标的精确性和稳定性.采用自适应控制的思想,以满足请求平均响应时间为目标,提出了一种基于在线评估系统性能模型的保障机制,并采用两个不同类型的事务性Web测试基准,对所提方法进行了评价.结果表明,该方法能够有效减轻变化负载模式下响应时间与预期目标的偏离程度.

Relocation, reproduction and remaining alive in the orb-web spider

When mortality is high, animals run a risk if they wait to accumulate resources for improved reproduction so they may trade-off the time of reproduction with number and size of offspring. Animals may attempt to improve food acquisition by relocation, even in 'sit and wait' predators. We examine these factors in an isolated population of an orb-web spider Zygiella x-notata. The population was monitored for 200 days from first egg laying until all adults had died. Large females produced their first clutch earlier than did small females and there was a positive correlation between female size and the number and size of eggs produced. Many females, presumably without eggs, abandoned their web site and relocated their web position. This is presumed because female Zygiella typically guard their eggs. In total, c. 25% of females reproduced but those that relocated were less likely to do so, and if they did, they produced the clutch at a later date than those that remained. When the date of lay was controlled there was no effect of relocation on egg number but relocated females produced smaller eggs. The data are consistent with the idea that females in resource-poor sites are more likely to relocate. Relocation seems to be a gamble to find a more productive site but one that achieves only a late clutch of small eggs and few achieve that.

Corrupção e poder local: transparência dos sítios web: estudo de caso

O presente trabalho versa sobre a temática da corrupção como fenómeno global e a sua influência nas mais diversos setores da atividade politica, social e económica. A sua prevenção e combate tem sido objeto das mais variadas intervenções a nível mundial, através da criação de organismos e mecanismos legais. No contexto nacional, esta problemática tem feito parte das políticas governamentais de vários governos, através da adoção dos vários mecanismos internacionais ratificados e transpostos para o ordenamento jurídico interno português, ao abrigo dos quais foram criados mecanismos de foro institucional e legislativo, como forma de tornar a sua atuação cada vez mais transparente. Entendemos realizar este estudo na perspetiva do poder local (municípios) e respetivos sítios web e tendo em conta que a informação é o pilar de uma Administração aberta e transparente aos cidadãos, quer na sua atuação, quer na sua responsabilização. Propõe-se neste estudo observar como se refletem as diversas imposições legislativas em matéria de informação (produção e publicidade) e demais mecanismos, na atuação dos municípios, sob ponto de vista da sua implementação nos sítios web. Para tal recorremos à vasta matéria legislativa existente e delineamos a nossa investigação ao abrigo da questão principal formulada, para qual propusemos algumas hipóteses de investigação, que nos propusemos aferir pela observação e análise on-line ao sítio web definido. As conclusões indicam que as questões de transparência e informação são o objetivo primordial de qualquer Administração aberta e responsável, cujo objetivo seja a prossecução do interesse público. Para além disso, constata-se que os diversos mecanismos legislativos constituem forte comprometimento na sua implementação, bem como condicionam a atuação dos decisores públicos em termos de desvios de comportamento e responsabilização.

Web based content and hybrid teaching: student perceptions of the effectiveness of using web based content and hyper-linked teaching units in teaching hybrid business and marketing post secondary classes /

This exploratory, descriptive action research study is based on a survey of a sample of convenience consisting of 172 college and university marketing students, and 5 professors who were experienced in teaching in an internet based environment. The students that were surveyed were studying e-commerce and international business in 3^^ and 4*'' year classes at a leading imiversity in Ontario and e-commerce in 5^ semester classes at a leading college. These classes were taught using a hybrid teaching style with the contribution of a large website that contained pertinent text and audio material. Hybrid teaching employs web based course materials (some in the form of Learning Objects) to deliver curriculimi material both during the attended lectures and also for students accessing the course web page outside of class hours. The survey was in the form on an online questionnaire. The research questions explored in this study were: 1. What factors influence the students' ability to access and learn from web based course content? 2. How likely are the students to use selected elements of internet based curriculum for learning academic content? 3. What is the preferred physical environment to facilitate learning in a hybrid environment? 4. How effective are selected teaching/learning strategies in a hybrid environment? The findings of this study suggest that students are very interested in being part of the learning process by contributing to a course web site. Specifically, students are interested in audio content being one of the formats of online course material, and have an interest in being part of the creation of small audio clips to be used in class.
