Easy referencing with Zotero

Friday, May 23rd, 2014

It’s safe to say that every university student will write at least one written piece (essay, report, etc.) requiring referencing during his/her time as student. It’s also safe to say that mentioning the word “referencing” to most of these students will, at the very least, make their smiles drop or, in a worst-case scenario, lead to them running away, screaming and wildly swinging their arms in the air.

This is quite understandable.

Manual referencing – keeping track of your sources, making sure you have the correct information on them and, finally, citing them in the right places in the right style – is a horrid experience. It’s mundane, laborious and very time-consuming. While many facets of doing research have evolved tremendously over the past decades, it’s rather curious that a simple and easy solution to this persistent problem has not yet been developed.[1]

That is, of course, until the advent of Zotero. In the following sections we’ll look briefly at how Zotero works in an effort to show why some consider it to be the best thing since sliced bread.

What is Zotero and how do I get it?

Zotero is a free, open source software package that you can install on your PC, Mac or Linux-based computer. It runs as an “add-on” within the Mozilla Firefox browser (which is also free and open source) and integrates deeply with your referencing process, greatly simplifying all of its steps: collecting sources, keeping them organised and citing them – in the correct style – in your paper, essay or report.

To install Zotero, make sure you have Firefox installed. If not, first download Firefox. Open Firefox. Then go to this page and click the “Zotero for Firefox” button.[2]

In our next edition we’ll have a closer look at how Zotero works and give you some advanced tips on how to get the most out of your Zotero.


[1] To be fair, a number of referencing software packages have been available for a considerable time. However, none of them have made the referencing experience truly frictionless to the extent that Zotero does.

[2] Zotero is also available as a standalone package (i.e. outside the Firefox browser), but it’s much easier to use within the Firefox browser.

Easily manage your postgraduate students’ information

Friday, May 23rd, 2014

Managing postgraduate students is a lot of work, but NAO can help you.  Have you ever wished that information about postgraduate students of your Faculty or Department was more readily available?  If you have never used NAO before, now is the time to to find out more and save yourself a lot of trouble in future.

The following remarks have been made about the system and you can decide for yourself whether they sound promising or not:

“Why haven’t I heard about the system before … grrrr.”
“NAO is the best thing that has happened in my career during the past few years!”
“Wow! Now I never have to hunt for a student number again … “

NAO is the abbreviation for Nagraadse Akademiese Ondersteuning/Postgraduate Academic Support; a web-based system designed specifically for staff members involved with the management of postgraduate students.

Honestly, you can get rid of the spreadsheets you have used year after year to keep track of important information, because everything you need is  available via NAO, fresh from the central system every single morning.

Below is a list of various types of information available to make your life a bit easier:

  • Undergraduate final year students (for recruitment purposes)
  • Applicants from elsewhere – see how far the applications have progressed
  • Registered postgraduate students
  • Postgraduate students not registered yet
  • Lists of graduates form previous years
  • Historic information as far back as 2000 

Excel reports are available with as little effort as a mouse click, to enable you to do further data crunching,  filter options will narrow down your searches to only the records you are interested in and data on the screen can be sorted by clicking column headings.

At a glance and without lifting a finger the system shows whether a student

  • is from abroad as well as his/her nationality,
  • is currently being funded or has received funding in the past,
  • already has a study leader and / or thesis title captured to the central system,
  • has passed away and
  • information such as SU number, nickname, surname, programme, anchor module, email address, telephone number and much more is also immediately available. 

Something extra about the system worth mentioning, is that e-mails can be sent to groups of students.  Just create your own wording in both English and Afrikaans and e-mails will be sent to students in the correspondence language which they have chosen at registration. The same wording can be used year after year, for example to remind slowcoaches to register before a certain date to avoid paying a fine!

You will be able to create your own notes per student (e.g. John was out of action for a certain time as a result of influenza), get access to full study records, check funding to make sure departmental bursaries were awarded and get hold of lots more information.

The best news of all is that Study Leaders and Thesis Titles can be captured to the central system via NAO, which will spare you a lot of worrying about your hard drive crashing and destroying all your hard work of the past 6 months!

If you need more information, click here to see a Powerpoint presentation. Send email to Rita de Jager, Head: Postgraduate Academic Support at rd@sun.ac.za to be given access, scheduled for a training session or to ask further questions about NAO.

Plugged or unplugged?

Friday, April 11th, 2014

Until recently our area of work was determined by the length of the cable connecting our computer to the network point. This was before Wi-fi  became the norm in our lives.

Wi-Fi services provide staff and students with wireless connection to the US network. Unfortunately, with wi-fi, the expectation is created that it will always work perfectly and be accessible. Expectation and reality don’t necessarily correspond and this leads to frustration amongst users.

Realistically speaking Wi-fi  is a best effort and various factors such as your physical distance from the wireless access point (WAP), WAPs influencing each other and structures in the way of the signal, play a large role.

Let’s look at the technical details –

Wi-fi networks have a limited range. The standard WAP uses 802.11b or 802.11g and with a standard antenna it will cover a range of 35 metres indoors and 100 metres outside. Reception can be improved by installing a higher gain antenna and adapting the antenna’s direction.

Due to the complex nature of radio propagation at typical wi-fi frequencies, especially the effect of signals bouncing off trees and buildings, algorithms can only approximately predict Wi-Fi signal strength for any given area in relation to a transmitter.

Wi-fi connections can also be interrupted or slowed down due to other devices in the environment. Wi-fi pollution or too many access points can prevent access and interfere with other devices’ use of other access points. This is caused by overlapping channels on the 802.11g/b spectrum and can lead to a problem in densely populated areas or office buildings with many Wi-fi access points.

On our campuses the maximum connections to a hotspot (or WAP) are limited to 25 to 35 and the rest are denied access. The devices connected to a hotspot at a given moment have to share the output and the higher the number of devices, the less efficient the communications.

Other devices such as microwave ovens, ISM band devices, security cameras, cordless phones, baby monitors and amateur radios also use the 2.4 GHz band and this can cause significant interference.

Given all these factors, it is clear that Wi-fi  isn’t always the best option for a stable, dependable network connection. If you are working from your office, rather plug your computer in at the network point and use Wi-fi  only for emergencies or when you move around on campus.

 


If you want to register for use of Wi-fi on campus, contact the IT Service desk at +27 21 808 4367 or send an e-mail to help@sun.ac.za with the following information: 

  • Building
  • Room number
  • US number
  • Username
  • Asset number of device or description of the device
  • Network card address (also known as the MAC address)

Access to Wi-fi services on campus take place via the Secure or MatiesWifi SSIDs. Devices with asset numbers are generally registered on Secure, where they have access to all network services. Other devices are registered on MatiesWifi with limited access to services. Both these SSIDs provide a speed of up to 54 Mbps.

For more information, contact the IT Service Desk or telecom@sun.ac.za

Download the mobile Inetkey application

Friday, February 14th, 2014

With the growing amount of mobile applications used on a daily basis, a need arose for a simple, effective Inetkey application that can be used on all devices and platforms – including Android, iOS, Blackberry and Windows.

After extensive testing on most available platforms, the official Inetkey app was launched on iOS, Android, Windows and Blackberry. You can download the appropriate version by clicking on the links below.

Non-official Inetkey mobile applications exist, but have been developed by independent individuals and are not supported or endorsed by Information Technology. Unofficial Inetkey apps carry the risk that they may intercept users’ credentials, which could be abused or stolen.  A user keys credentials into an app and does not know how or where they are stored or communicated, or even if it’s secured.

We can accept no responsibility if users download these apps and experience problems.
