Emily Jacometti

Emily talks about running a startup in Amsterdam (NL), having founded three companies in the last twelve years. She shares her thoughts on how to build a company, how to create a product and culture that people love, how to set up a growth strategy and how to grow a company. And maybe the best part: her stories about rising to succes but also the failures that she faced in the last years as a woman in Tech. She talks honestly about starting a company in a garage and the adventure that followed.

Stacey Jeffery: A Primer on Quantum Algorithms

I will give an introduction to quantum algorithms. Why are quantum computers better than classical computers? What problems can they solve faster than classical computers, and how much faster? I will scratch the surface of these questions in my talk.

Fenia Aivaloglou: Gender differences in computing education

Programming education currently starts early, through both school classes and after-school programs. Can this early introduction to programming help in bridging the gender gap in computer science? And are boys different than girls in programming classes? In this talk I will present our findings from experimental programming courses that we have run in elementary schools, as well as the reported perceptions of code club instructors on the gender differences among their students.

Alexander Serebrenik: Gender in open-source software development

In this talk I will provide a brief overview of several recent studies of gender and gender diversity in software development teams. Our main findings:

• More gender-diverse GitHub teams are not only more productive than less gender-diverse ones (Vasilescu et al. CHI 2015), but they are also less likely to exhibit suboptimal communication patterns (Catolino et al., ICSE-SEIS 2019) known to lead to suboptimal code patterns (Palomba et al., TSE 2019).
• Social capital obtained by collaboration in GitHub open source projects is beneficial for duration of engagement in an open source project; diversity of information ties, i.e., involvement in very different projects, is beneficial for people of all genders, more so for women than for men (Qiu et al., ICSE 2019).
• If the time permits, I will also touch on the ongoing work related to going beyond gender binary. In this preliminary study has been based on interviews of three transgender women working in software development, we have observed that remote work, facilitated by technological solutions, reduces barriers for participation in software development projects. We conjecture that remote work can benefit other underrepresented minorities as well (Ford et al., ICSE-SEIS 2019).

Anna Sperotto: Denial of Service - a tale of attacks, measurements and countermeasures

Most people intuitively knowns what Denial of Service attacks are. You might have heard about it in the news, or even worst, you might have experienced one first hand as a victim. But what happens behind the scenes? In this talk we will discuss why DoS have become one of the most effective and most used attacks on the Internet nowadays, what we do know and do not know (yet) about this problem, and how victims are taking measures against these attacks.

Joyce Westerink: Estimating stress-induced cortisol variations from skin conductance measurements

In search for a stress indicator that can be used to monitor stress with wearables, we investigated the effect of psychological stress on skin conductance, which is known to be almost instantaneous. In addition, we looked at the effect of stress on the stress hormone cortisol, which is known to peak about 20-30 min later. Then, the relation between the two effects was modeled as a convolution of the height of the skin conductance peaks with the cortisol stress response curve. We used it as a skin conductance-derived estimate of stress-induced cortisol. In a first experiment to validate this model we compared the stress-induced cortisol estimates with cortisol levels actually measured in saliva samples. Forty-six participants completed a series of stressful, boring, and performance tasks, while skin conductance was measured continuously and salivary cortisol samples were taken at regular intervals. We divided subjects in high-cortisol responders and low-cortisol responders according to their increase or decrease in measured salivary cortisol during the stressful task. For both groups, we found that the correlation between the skin conductance-based stress-induced cortisol estimates on the one hand and the measured salivary cortisol on the other hand, were substantial. In addition, we calculated the (Fisher-corrected) mean within-participant correlation between these variables, and found it to be 0.48. We conclude that these results underwrite the use of the skin conductance-based stress-induced cortisol estimates as a stress indicator reflecting in-body cortisol levels.
