Unraveling the Skillsets of Data Scientists: Text Mining Analysis of Dutch University Master Programs in Data Science and Artificial Intelligence
The growing demand for data scientists in the global labor market and the
Netherlands has led to a rise in data science and artificial intelligence (AI)
master programs offered by universities. However, there is still a lack of
clarity regarding the specific skillsets of data scientists. This study aims to
address this issue by employing Correlated Topic Modeling (CTM) to analyse the
content of 41 master programs offered by seven Dutch universities. We assess
the differences and similarities in the core skills taught by these programs,
determine the subject-specific and general nature of the skills, and provide a
comparison between the different types of universities offering these programs.
Our findings reveal that research, data processing, statistics and ethics are
the predominant skills taught in Dutch data science and AI master programs,
with general universities emphasizing research skills and technical
universities focusing more on IT and electronic skills. This study contributes
to a better understanding of the diverse skillsets of data scientists, which is
essential for employers, universities, and prospective students
Nasal oxytocin administration does not influence eye gaze or perceived relationship of male volunteers with physicians in a simulated online consultation: a randomized, placebo-controlled trial
The patient–physician relationship is a critical determinant of patient health outcomes. Verbal and non-verbal communication, such as eye gaze, are vital aspects of this bond. Neurobiological studies indicate that oxytocin may serve as a link between increased eye gaze and social bonding. Therefore, oxytocin signaling could serve as a key factor influencing eye gaze as well as the patient–physician relationsh ip. We aimed to test the effects of oxytocin on gaze to the eyes of the physician and the patient–physician relationship by conducting a randomized placebo-controlled crossover trial in healthy volunteers with intranasally administered oxytocin (with a prev iously effective single dose of 24 IU, EudraCT number 2018-004081-34). The eye gaze of 68 male volunteers was studied using eye tracking during a simulated video call consultation with a physician, who provided information about vaccination against the human papillomavirus. Relationship outcomes, including trust, satisfaction, and perceived physician communication style, were measured using questionnaires and corrected for possible confounds (social anxiety and attachment orientation). Additional secondary outcome measures for the effect of oxytocin were recall of information and pupil diameter and exploratory outcomes included mood and anxiety measures. Oxytocin did not affect the eye-tracking p arameters of volunteers’ gaze toward the eyes of the physician. Moreover, oxytocin did n ot affect the parameters of bonding between volunteers and the physician nor other secondary and exploratory outcomes in this setting. Bayesian hypothesis testing provided evidence for the absence of effects. These results contradict the notion that oxy tocin affects eye gaze patterns or bonding

The growing demand for data scientists in both the global and Dutch labour markets has led to an increase in data science and artificial intelligence (AI) master programs offered by universities. However, there is still a lack of clarity regarding the specific skills of data scientists. This study addresses this issue by employing Correlated Topic Modeling (CTM) to analyse the content of 41 master programs offered by 11 Dutch universities and an interuniversity combined program. We assess the differences and similarities in the core skills taught by these programs, determine the subject-specific and general nature of the skills, and provide a comparison between the different types of universities offering these programs. Our analysis reveals that data processing, statistics, research, and ethics are the core competencies in Dutch data science and AI master programs. General universities tend to focus on research skills, while technical universities lean more towards IT and electronics skills. Broad-focussed data science and AI programs generally concentrate on data processing, information technology, electronics, and research, while subject-specific programs give priority to statistics and ethics. This research enhances the understanding of the diverse skills of Dutch data science graduates, providing valuable insights for employers, academic institutions, and prospective students.</div
