Grounded Theory

nospam@example.com (Jorge Cardoso) — Tue, 31 Jan 2012 10:13:44 -0500

Grounded Theory is a methodology to produce theory based on empirical data. Instead of starting with a well defined hypotheses, GT starts with an area of study and inductively derives a theory from the data gathered around that area. So, the purpose is not to prove a theory, but to generate one.

GT was developed by Barney Glaser and Anselm Strauss and published in [1].

Phases

GT can be roughly decomposed in 5 parts (which are not totally sequential):

Pervasive Advertising book

nospam@example.com (Jorge Cardoso) — Fri, 21 Oct 2011 23:10:45 -0400

The Pervasive Advertising book where I co-author a chapter is just out! Check it out, particularly this chapter :)

About the book (from Springer webpage):

Following decades of exciting developments in laboratories around the world, pervasive computing technologies are starting to reshape our world in real ways. Computers, visible and invisible, are everywhere: traditional signs and billboards are being replaced by digital signage, projections, and interactive surfaces. Communication is digital and ubiquitousthe majority of the worlds population uses mobile phones. Physical computing and robotics make physical environments digital and interactive. It is apparent that analogous for developments on the Internet, advertising will be the business model driving pervasive computing. These new computing technologies are powerful tools for advertising and they will supersede traditional advertising in the near future. Pervasive computing is the disruptive technology for advertising. This book presents the core principles of Pervasive Advertising and makes accessible to practitioners and researchers alike research findings in pervasive computing, modern advertising, and human-computer interaction. The major opportunities addressed include: symmetric communication, the long tail, powerful experiences, personalization, context adaptivity, audience measurement, and automated persuasion. The major challenges addressed include: calm and engaging advertising, privacy, and ethical persuasion. This book presents and discusses innovative applications based on digital signage and mobile advertising, venturing into new territories like music and scents. This book is intended as a guide for: Advertisers who want to understand how new technologies revolutionize their field. Pervasive computing engineers and researchers who want to understand what business models will drive their technologies in the real world. Anyone who is interested how pervasive advertising will shape the future of urban life.

Notes from CAMS 2009

Springer Bibtex Converter

nospam@example.com (Jorge Cardoso) — Thu, 15 Oct 2009 16:05:16 -0400

I don't know why SpringerLink does not provide the BibTeX for its entries, but fortunately there is a web tool that converts the Springer link into BibTeX: Springer Bibtex Converter. You just have to paste the link into the textbox and submit it. There is even a bookmarklet so all you have to do is to open the Springer page and press a bookmark to convert it to BibTeX. Nice. Thank you William Niu.

I have already posted about bibliographic references with Jabref, and how it could be used to create a list of published papers to include in a web page.

However, there's a far better way to keep a list of publications on your personal web page if you use BibTeX (and you should, Google uses it!): Bibtexbrowser.

How to write consistently boring scientific literature

nospam@example.com (Jorge Cardoso) — Sat, 25 Jul 2009 10:59:07 -0400

A light, interesting and funny article about scientific writing. Although I do not agree that an impersonal leads to a boring reading, the article provides a list (a more or less common list) of recommendations to write interesting scientific literature (in an inversed logic).

Another good paper on writing for academic papers with similar advice is The Ten Commandments for writing academic papers by Dra. Julienne Hanson.

The Research Methods Knowledge Base - William Trochim

nospam@example.com (Jorge Cardoso) — Fri, 22 May 2009 15:56:41 -0400

Another (aparently, I haven't finished it) good book about research design. In a more informal (yet accurate) language than the previous book, it describes epistemology, research questions, hypotheses, sampling, measurement, analysis...

Research Design: Qualitative, Quantitative, and Mixed Methods Approaches - John W. Creswell

nospam@example.com (Jorge Cardoso) — Thu, 21 May 2009 10:11:42 -0400

A great book for those beggining to write a PhD proposal. It talks about the different types of knowledge claims and the typical research methods associated with them. It also offers very specific advice and even templates for content for different sections of the proposal such as the Introduction and Objectives sections. I found it a very practical book.

In Traction: How to efficiently perform a literature review

nospam@example.com (Jorge Cardoso) — Tue, 14 Apr 2009 15:41:10 -0400

A good text on literature review methodology. It may seem obvious at the end and you might feel that you already do most those steps, but I think it is still important to see it all layed down and structured on a text like this.Â

Secrets to success and fatal flaws: the design of large-display groupware - Review

nospam@example.com (Jorge Cardoso) — Thu, 19 Mar 2009 18:27:12 -0400

The paper surveys large-display systems that use wall displays to find the main factors that lead

to the success or failure in usage of the system. Seven groupware systems were analyzed:

Notification Collage, MessyBoard, Plasma Poster, Semi-Public Displays, BlueBoard, MERBoard

and Awareness Module.Â

A InovaÃ§Ã£o: World Wide Web

nospam@example.com (Jorge Cardoso) — Thu, 05 Feb 2009 18:07:13 -0500

A histÃ³ria da Web, contada por Tim Berners-Lee, Ã© uma histÃ³ria muito interessante.

Como tive de fazer um trabalho sobre uma inovaÃ§Ã£o para o programa de doutoramento, escolhi a Web e comprei o livro:

Weaving the Web : The Original Design and Ultimate Destiny of the World Wide Web by its Inventor

Li-o em trÃªs meios dias.Â Ã impressionante a velocidade a que as coisas aconteceram, a evoluÃ§Ã£o da Web e alguns dos jogos de interesses Ã volta dela. O livro Ã© de 1999, por isso, obviamente, nÃ£o conta a histÃ³ria toda.Â

Recomendo a leitura deste livro e do texto que escrevi sobre o assunto: http://jorgecardoso.eu/PhD/Inovacao/InovacaoWWW.html.O texto nÃ£o Ã© um resumo do livro, mas antes uma anÃ¡lise sob o ponto de vista da concepÃ§Ã£o da inovaÃ§Ã£o (causas, tecnologias relacionadas, evoluÃ§Ã£o, actores, etc). CorrecÃ§Ãµes e comentÃ¡rios sobre o texto sÃ£o bem-vindos neste post.

Using camera-phones to interact with context-aware mobile services - Review

nospam@example.com (Jorge Cardoso) — Wed, 07 Jan 2009 18:59:44 -0500

Here's another review...

Using camera-phones to interact with context-aware mobile services

In this technical report [Toye et al., 2004], the authors present the results from a study on a new interaction technique that uses camera-phones and visual tags to interact with public displays.

The technique consists in using visual codes in printed form or in dynamic displays that a camera-phone can recognize. The mobile phone communicates with a computer so that when a user 'clicks' on a tag, the display can reflect that action as if a button was pressed, for example. Also, the mobile can be used as a secondary display and also store information and personal data that is sent automatically to create a personal interface.

Touch & Interact: Touch-based Interaction of Mobile Phones with Displays - Review

nospam@example.com (Jorge Cardoso) — Tue, 06 Jan 2009 18:04:02 -0500

Here's my review...

Touch & Interact: Touch-based Interaction of Mobile Phones with Displays

In [Hardy and Rukzio, 2008], the authors present an interaction technique-Touch & Interact-with public displays using a mobile phone to touch the display.

The technique uses a mesh of RFID tags (10x10) on a projection surface. The mobile phone is capable of reading the tags and communicates the tag id, via Bluetooth, to a computer that controls the projections. The location of each tag is predefined, so its possible to determine the location on the screen that was touched by the phone.

The Design Space of Ubiquitous Mobile Input - Review

nospam@example.com (Jorge Cardoso) — Mon, 05 Jan 2009 18:37:01 -0500

Here's my review. Comments are appreciated...

The Design Space of Ubiquitous Mobile Input

[Ballagas et al., 2008] presents a design space of mobile input techniques with five dimensions: graphical subtask (position, orient and select), dimensionality, relative vs absolute movement, interaction style (direct vs indirect) and feedback (continuous vs discrete).

Hybrid Recommender Systems: Survey and Experiments - Review

nospam@example.com (Jorge Cardoso) — Mon, 15 Dec 2008 16:48:14 -0500

Here's my review. Comments are appreciated...

Hybrid Recommender Systems: Survey and Experiments

In [Burke, 2002], Robin Burke makes a survey of existing recommender techniques and systems and he also presents and evaluates a hybrid recommender system.

Burke defines a recommender system as "any system that produces individualized recommendations as output or has the effect of guiding the user in a personalized way to interesting or useful objects in a large space of possible options." Put differently, a recommender system assists users in finding relevant information (for the specific user) from a large information space.
