This deck briefly outlines the work we did mapping the South African Twittersphere for the 2012 SAMRA conference, including some analyses we did based on the structure of the network. Specifically, we identified people with the potential for influence based on their betweeness centrality and Authority (HITS). In addition, we also used a modularity algorithm to identify 5 clearly distinct communities within the graph. The results are for interest-sake only and should be interpreted within the limitations of the data."
A deck presented at the MRS 'Maximising the Value of Big Data' conference in London, January 2013.
Presents my view of big data and the potential it gives us for mapping the systems that we deal with on a day-to-day basis. Big data holds the promise of providing us with a meta-view of the systems that we all think we are so familiar with. I think we will find that the woods look nothing like the trees.
Using network science to understand elections: the South African 2014 nationa...Socialphysicist
This presentation describes our research into the roughly one million tweets that we collected in the run-up to the 2014 national elections in South Africa. It uses a mixture of network theory and data science to unpack the main communities and topics of conversation. The paper won the Gold Award for Best Paper at the 2015 SAMRA conference.
International Customer Experience World PresentationChantel Botha
Design tips for brands who want to be loved in social media
In this mobilized, socialized world it becomes more and more important for brands to understand the consumer’s always changing expectations. I now expect my grocer to tweet back in 10 minutes because my bank does it and I expect my favourite neighbourhood coffee shop to give me discounts when I check in on Foursquare because Starbucks does it.
The experience designer is faced with challenges that the always on-net and social consumer creates through their reasonable and sometimes unreasonable expectations. Word of mouth has turned into word of the ever mighty thumb and in his mobile world, all I have to do is tweet a brand about how angry they make me and instantly I can influence the purchasing behaviour or my and their followers.
This presentation will share insights of how to design experiences for the traditional and now social channels with the aim to be transparent, consistent, authentic and true to the brand’s essence.

A network based model for predicting a hashtag break out in twitter Sultan Alzahrani
Online information propagates differently on the web, some
of which can be viral. In this paper, first we introduce a simple standard deviation sigma levels based Tweet volume breakout definition, then we proceed to determine patterns of re-tweet network measures to predict whether a hashtag volume will breakout or not. We also developed a visualization tool to help trace the evolution of hashtag volumes, their underlying networks and both local and global network measures. We trained a random forest tree classifier to identify effective network measures for predicting hashtag volume breakouts. Our experiments showed that “local” network features, based on a fixed-sized sliding window, have an overall predictive accuracy of 76 %, where as, when we incorporate “global” features that utilize all interactions up to the current period, then the overall predictive accuracy of a sliding window based breakout predictor jumps to 83 %.
Network centrality measures and their effectivenessemapesce
Often centrality measures are used in social network analysis. The goal of this presentation is to explain how different centrality works and how they can be compared.

Social Network Analysis: applications for education researchChristian Bokhove
What is your talk about?
This seminar will illustrate various social network analysis (SNA) techniques and measures and their applications to research problems in education. These applications will be illustrated from our own research utilising a range of SNA techniques.
What are the key messages of your talk?
We will cover some of the ways in which network data can be collected and utilised with other research data to examine the relationships between network measures and other attributes of individuals and organisations, and how it can be linked to other approaches in multiple methods studies.
What are the implications for practice or research from your talk?
SNA is an approach that draws from theories of social capital to study the relational ties that exist between actors or institutions in a specific context. Such ties might include learning exchanges or advice-seeking interactions. SNA techniques allow researchers to incorporate the interdependence of participants within their research questions, whereas many traditional techniques assume our participants, and their responses to our questions, are independent of one another.
Social Media as a Relationship Management ToolMaureen Kuether
This presentation will define the public relations theory of relationship management and identify how it can be utilized through social media by examining social analytics applications. Moving away from traditional measurements focused on quantity, organizations should measure their success based on the quality of the relationship between an organization and its publics and can do so using social analytics.
Unlocking the True Value of Social Media Holly Ross
Everywhere you turn there are tons of great stories about organizations doing wonderful things online to build communities and engage their supporters through Social Media. But what is it all for? We’ve all heard the sayings “If you build it, it will come”, “the value of Social CRM”, other concepts around understanding what is the value of Social Media. In this session, we’ll explore the notion that the real value of Social Media is not only in the experience of the community itself, but also in having a greater understanding of how your supporters are engaging with your online communities. This information can be invaluable to both marketers and fundraisers as they attempt to communicate to these engaged members of their community.

Australian Political Parties and social media: uses and attitudesStephen Dann
Australian Political Parties and social media talks about how the Twitter accounts of political candidates from the W.A. senate re-election fared under analysis from the Twitter Content Classification framework (Plus a brief overview of Day 1 of the #cmpm2014 conference)
An introduction to the value of social media in the world of aquatics programming. This presentation and information will be useful for people starting in social media for work - the information is high level and provides a start for further exploration.
This deck summarises some of our research into the "shape" of conversation maps (i.e. interaction networks) on Twitter. We find that the shape, or pattern, of brand and campaign conversations tend to sit on a continuum from centralisation to decentralisation. The shapes often evolve along this continuum as brands adopt more organic, two-way conversation patterns rather than the one-directional broadcasting techniques so common in traditional channels such as television and radio.
This presentation is based on a paper that won the Best Methodological Paper award at the 2015 ESOMAR Congress conference. You can access the paper here: https://www.esomar.org/web/research_papers/Innovation_2714_The-Shape-of-Conversations.php
This presentation looks at how gamification taps into how our brains work. It focus on the role of reward schedules and uncertainty in creating engagement. It also briefly discusses whether or not the term 'gamification' itself is a fad or not.

Beneath the Surface: The Hidden World of Individual Buying DynamicsSocialphysicist
This deck describes how people actually buy brands based on an analysis of several million purchase events over a period of 5 years across three different categories in the United Kingdom.
It was presented at the ESOMAR Congress 2012 conference in Atlanta, USA in September 2012.
I'm particularly proud of the illustrations in the presentation... although the fundamental nature of the research is pretty cool too :)
We presented this deck at the ESOMAR Congress 2011 conference in Amsterdam where it was nominated for "Best Methodological Paper".
The meat of this deck is a collection of case studies showing the efficacy of gamification in various BUSINESS contexts. It took us ages to contact and collate these various examples, so hopefully having them all in one place will save you time.
A big thank you very much to the various folks who helped us put this piece of research together!
If you have any questions, comments, requests, or are interested in the original paper that this deck is based on, please feel free to drop us a line :)
This presentation reviews how attention works in our brains. It answers questions like:
1) How do we process our environment?
2) What is the path that stimuli go through?
3) What are the factors that capture our attention?
4) What about stimuli that we don’t consciously process?
5) And more...
This is my second presentation from the SAMRA 2011 conference. The first presentation on "gamification" can be found here: http://www.slideshare.net/ervler/gamification-future-or-fail
This deck is based on a paper we wrote for the SAMRA 2011 conference. It's a short introduction to some of the ideas underlying the concept of "gamification".
It also details the results from a simple experiment we conducted to measure the effectiveness of gamifying an online community. We were restricted by a tight deadline and the existing capabilities of the online platform we partnered with, but the results are still pretty clear (although small base sizes makes it difficult to draw solid conclusions). To follow up these tantalising results, we are writing another paper for ESOMAR Congress that collects more numbers describing the effectivness of gamification.
I had a lot of fun illustrating the deck. Hope you enjoy reading it.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
