The original context and method which generated this number had two weaknesses, both of which we address. First, it relies on undocumented, judgment-based factors to estimate the number of end user programmers based on the total number of end users; we address this weakness by identifying specific end user sub-populations and then estimating their sizes. Second, Boehm's estimate relies on additional undocumented, judgment-based factors to adjust for rising computer usage rates; we address this weakness by integrating fresh Bureau of Labor Statistics (BLS) data and projections as well as a richer estimation method. With these improvements to Boehm's method, we estimate that in 2012 there will be 90 million end users in American workplaces. Of these, we anticipate that over 55 million will use spreadsheets or databases (and therefore may potentially program), while over 13 million will describe themselves as programmers, compared to BLS projections of fewer than 3 million professional programmers. We have validated our improved method by generating estimates for 2001 and 2003, then verifying that our estimates are consistent with existing estimates from other sources.","PeriodicalId":241986,"journal":{"name":"2005 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC'05)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124813761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through Web service composition new added value Web services can be created out of existing ones. Examples of these compositions are virtual organizations, outsourcing, enterprise application integration, business process definitions and business to business inter/intra-enterprise relationships. In order to enable the construction of business processes as composite Web services, a number of composition languages has been proposed by the software industry. However, the handiwork of specifying a business process with these languages through simple text or XML editors is tough, complex and error prone. Visual support can ease the definition of business processes. In this paper, we describe ZenFlow, a visual composition tool for Web services written in BPEL4WS. ZenFlow provides several visual facilities to ease the definition of a business process such as multiple views of a process, syntactic and semantic awareness, filtering, logical zooming capabilities and hierarchical representations.","PeriodicalId":241986,"journal":{"name":"2005 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC'05)","volume":"15 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126858836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to foster active learning, educators have explored algorithm visualization systems that empower learners to construct their own visualizations of algorithms under study. Notably, these systems support a similar development model in which coding the algorithm is temporally distinct from viewing and interacting with the resulting visualization. To explore the benefits of narrowing the gap between coding an algorithm and viewing its visualization, we have implemented \"What You See Is What You Code\", a novel, \"radically dynamic\" development model to facilitate learner-constructed algorithm visualizations. In this model, the line of algorithm code currently being edited is reevaluated on every edit, leading to the dynamic update of an accompanying visualization of the algorithm. Analysis of usability studies involving introductory computer science students suggests that the immediacy of the model's feedback can help novices to quickly identify and correct programming errors, and ultimately to understand their code's execution.","PeriodicalId":241986,"journal":{"name":"2005 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC'05)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127048150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Star Logo and NetLogo were the first systems to allow middle and high school children to build dynamic models from many thousands of programmable particles. This has inspired Kedama: an authoring system that simplifies the scripting and construction of massively parallel models to allow more students to join in this new rich environment. This has given rise to new user interface and programming language designs. Kedama has the following notable features: 1) scripts in Kedama can be written in a graphical tile scripting interface. Its users are alleviated from syntax errors, and all program elements are visually presented to the user. 2) Kedama is an extension of Squeak eToys: children who have learned to \"script in the large\" can use same techniques to \"script in the small\" with many thousands of objects. 3) The semantics and syntax are simplified but retain full power of expression. 4) The ill in Kedama is dynamic: scripts and other properties in Kedama can be dynamically modified while scripts are kept running. 5) Kedama is more portable, being able to run on more than two dozen types of platforms, including the most used around the world. 6) Kedama is fast. Various simulations typically run about 3 times faster than previous systems. This improvement made it possible to write different classes of examples.","PeriodicalId":241986,"journal":{"name":"2005 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC'05)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122074324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
