If you are starting a more "professional" academic journey, as a master or PhD student, I strongly recommend that you use a reference manager to help you organize and keep track of the things you read.
The two main roles of a reference manager are: a) help you organize papers and books you read and b) facilitate citation and referencing when producing your own text. The most common options I know are EndNote, Mendeley and Zotero. The first is paid and proprietary. The second is free (of charge) but not open source (although very friendly with users). The latter is free (of charge) and open source, so it is my choice!
Below, I will present basic steps to set up Zotero, recommend some good practices, offer some specific tips that are useful for me and, finally, make some comments on advanced features.
The only limitation that is worth mentioning is the fact that Zotero does not have a built-in pdf reader, as Mendeley (I do not know about EndNote). So, every time you open a PDF stored on your collection, Zotero launches the reader on your system and you have to make notes, highlightings and annotations in it. I actually prefer this way (I like my PDF reader - Okular), but some people may prefer a built-in reader to stay always inside the same environment.
Most of the info in this post is also on this pdf that I used in a presentation at the 2017 PGR Conference - School of Education, University of Nottingham. Feel free to use and distribute it :)
Before the instructions, some comments on the interface. On the left you have the organizational features: collections (similar to folders) and list of tags (on the bottom). On the middle you have your entries (each entry can have sub-items such as the actual pdf file, notes written on zotero, images, etc). On the right you can see the metadata of the entry selected in the middle column (basic info such as authors, title, journal, etc), notes (you can use this features to attach your comments on the entry for instance), tags and a list of related papers. Note that Zotero can fill the basic info for you, but the other tabs have to the generated by you.
The three ways to add a source are:
In terms of organization, I recommend to use lots of tags (easier to combine) and be more selective with the Collections. Finally, check regularly the “Duplicated Items” collection to avoid surprise in the future when writing.
This is a suggestion I read online a long time ago and found very useful during my PhD.
Zotero allows you to create collections and subcollections, which can be flexibly reorganized and renamed according to your wishes. My suggestions is: create a structure of collections that mimics the structure of your thesis. Of course you are going to change your mind during the process, but you can reorganize the collections as well to keep some resemblance.
I found this useful to recollect in the future, when you start to actually write up your thesis, the papers you read in the beginning of your research. So, when you get to your Methods section, let's say, you can check the references on your Methods collections. This way, you do not have to rely on your memory.
Zotero's Advanced Search is extremely powerful, allowing you to create searches combining collections, tags, search on all the fields of an entry with regular word searches. Also, it allows you to save the searches in case you want to use them in the future. This can be very powerful if well utilized.
Also, Zotero organizes the metadata in a readable and intelligible database. That is the part I love about open source! If you need to fiddle with the metadata in a way that is not supported by the software, you can open this file using any database tool and read it! And script it!
Last week the crowdfunding campaign for Librem 5 finished and they achieved their goal! Actually, they exceeded it in 42%, with more than 2 million dollars raised when the goal was 1.5 million. This was a huge achievement and since they are going fully open (hardware and software) and think this could be the beginning of linux's on mobiles. Although open software may never get a significant market share on mobiles, I am very glad that this option will exist and will be viable!
My only issue with the Librem 5 is its price. I do not like mobiles, I have one because it is convenient. So, I would never pay 600 dollars in such a device. My latest devices is a second hand Nextbit Robin that costed me 130 pounds. The device was chosen because it is considered (by some reviewers) as one of the best to run Lineage OS and because I could find a second hand in good conditions.
Unfortunately, as I use some google services and I could not make the mobile work as I needed without the basic google apps. So, my solution was to install OpenGApps (the micro version), which allowed me to use Gmail, Google Calendar and Play Store with no hustle. I know there is a lot of proprietary code behind these apps and services, but I feel this is a viable step towards openness. The micro version does not include Google Maps, which was important for me since I was getting really bothered by its alerts tracking my location even when I was not actively using the app.
My next step was to install F-Droid, an Android app repository for free and open source. My intention is progressively identify good apps that may enable me to get ride of all google apps. So far, here are some recommendations:
Sparse RSS: basic rss reader to gather news and blog posts. The look is not that great, but it does what it is meant to do. The only annoying feature is that the user has to provide the full address to the rss file (it does not detect it from the basic url of a blog, for instance).
Pretty Good Music Player: folder based music player. Simple, intuitive and functional. The problem for me is that it is not possible to close the app from the status bar and I like this feature.
Vanilla Music: music player that offers the possibility of navigating your collection according to artists, albums and so on, but also according to folders. The status bar provided is very useful and functional. I am very satisfied with this app so far.
Any new app, I will post here.
A coleção Matemática Multimídia foi desenvolvida por uma equipe da Unicamp entre 2008 e 2011 da qual tive o prazer de fazer parte.
A coleção oferece mais de 300 objetos educacionais concebidos originalmente para o Ensino Médio (vários deles são compatíveis com Ensino Fundamental e Ensino Superior) em quatro formatos diferentes: áudios, experimentos, softwares e vídeos. Os experimentos são roteiros para atividades envolvendo algum tipo de material manipulativo em que os alunos têm a oportunidade de gerar dados, testar hipóteses e depois utilizar a matemática para formalizar as conclusões. Os vídeos (todos disponíveis no Youtube) têm 10 minutos de duração e variam bastante desde ênfase em aspectos históricos, passando por discussão de problemas e aplicações até a discussão e explicação de conceitos e procedimentos. Os áudios são especialmente variados, mas no geral valorizam aspectos culturais e uma abordagem mais leve da matemática. Finalmente, os softwares infelizmente estão fora de funcionamento por motivos técnicos.
Apesar de já ter mais de 6 anos de vida, a coleção Matemática Multimídia continua sendo utiliza em Licenciaturas de Matemática e por professores e alunos. Por enquanto, contamos apenas com relatos informais de colegas, contatos pessoais e entuasiastas, mas em breve devemos começar a organizar algum tipo de repositório de experiências. Por hora, gostaria de divulgar um vídeo filho da coleção que descobri no Festival de Vídeos Matemática promovido pela Unesp de Rio Claro.
Primeiro, vejamos o objeto que deu origem a este filho, o vídeo Jardim de Números:
Agora, vejamos o vídeo Resolvendo o Jardim de Números, criado por alunos do 3º Ano do Ensino Médio do Colégio SESI, Bandeirantes do Paraná:
Parabéns aos estudantes pelo bom trabalho!
