Poster Slide on "A Domain Terms Visualization Tool for Spreadsheets"

 In this poster presentation, we introduce a new spreadsheet visualization tool which was developed to demonstrate that it is possible to have an easy-to-use spreadsheet understanding and debugging tool that relieves users from spreadsheet details and lets them utilize more of their mental model of the application domain. The tool translates traditional spreadsheet formulas into problem domain narratives and highlights referenced cells.

The poster was presented at the 2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC) which was held between 28th July, 2014 to 1st August, 2014 in Melbourne, Australia.

Presentation Slides on "Visualizing the Problem Domain for Spreadsheet Users: A Mental Model Perspective"

In this paper presentation, we introduce a new spreadsheet visualization tool as well as an empirical evaluation of its usability and of its effects on mental models of users. The tool translates traditional spreadsheet formulas into problem domain narratives and highlights referenced cells. The tool was found to be easy to learn and helped the participants to locate more errors in spreadsheets. Furthermore, the tool increased the use of the domain mental model in error descriptions and appeared to improve the mapping between the spreadsheet model and the domain model.

Presentation Slides on "An Empirical Study of Spreadsheet Authors’ Mental Models in Explaining and Debugging Tasks"

The spreadsheet comprehension and debugging problem is still very much there. It is important to understand spreadsheet authors’ mental models when doing different spreadsheet process activities as it can help to understand why the spreadsheet process is so error-prone and it can also help to develop the right tools and techniques for spreadsheet activities. In the empirical study we conducted, we found that spreadsheet authors have at least three mental models: the real-world mental model, the domain mental model and the spreadsheet mental model.

Why I am a 'non-trinitarian' Seventh-Day Adventist (Part 4)

1 John 5:20-21 (NIV)

 

20 We know also that the Son of God has come and has given us understanding, so that we may know him who is true. And we are in him who is true by being in his Son Jesus Christ. He is the true God and eternal life. 21 Dear children, keep yourselves from idols.

1 John 5 (NIV)

1 Everyone who believes that Jesus is the Christ is born of God, and everyone who loves the father
loves his child as well. 4 for everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith. 5 Who is it that overcomes the world? Only he who believes that Jesus is the Son of God. 9 We accept man's testimony, but God's testimony is greater because it is the testimony of God, which he has given about his Son. 10 Anyone who believes in the Son of God has this testimony in his heart. Whoever does not believe God has made him out to be a liar, because they have not believed the testimony God has given about his Son. 11 And this is the testimony: God has given us eternal life, and this life is in his Son. 12 He who has the Son has life; he who does not have the Son of God does not have life. 13 I write these things to you who believe in the name of the Son of God so that you may know that you have eternal life. 20 We know also that the Son of God has come and has given us understanding, so that we may know him who is true. And we are in him who is true by being in his Son Jesus Christ. He is the true God and eternal life. 21 Dear children, keep yourselves from idols.

1 John 4 (NIV)

12 No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us. 13 We know that we live in him and he in us, because he has given us of his Spirit. 14 And we have seen and testify that the Father has sent his Son to be the Savior of the world. 15 If anyone acknowledges that Jesus is the Son of God, God lives in him and he in God. 16 And so we know and rely on the love God has for us. God is love. Whoever lives in love lives in God, and God in him.
