Will You Work with Us to Design a Robot? Boys’ and Girls’ Choices of Anthropomorphic Robots According to Their Gender
No full textThis study aimed to examine whether boys and girls demonstrate inclinations that drive them to select interactions with humanoid robots that share psychological and physical similarities with them and display gender characteristics aligning with their own. Forty-four students, aged 10 to 13, from two distinct primary school classes, engaged in a study where they interacted in a CAVE with a simulated humanoid robot with a gender of their choice, selected between male or female at the beginning of the procedure. They were instructed to assist the experimenter in the robot’s design process. Subsequently, participants were assessed for any gender stereotypes.
The results indicate that children generally exhibit a preference for interacting with robots of their own gender rather than those of a different gender. Notably, the study suggests that the perceived level of agency assigned to gendered robots may be influenced by the extent of hostile sexism. Specifically, an increase in hostile sexism corresponds to an augmented perception of male robots as possess- ing agentic qualities. Conversely, a different pattern, only marginally significant, seems to emerge in relation to benevolent sexism, where an increase in benevolent sexism is associated with a heightened perception of female robots as agentic technology
Expression-rich communication through a squeezable device
No full textThis paper presents Squeeze Me, a squeezable device used to grab attention from the mobile robot Care-Obot, providing ground for expressive values to be shared between person and robot in a smart environment. Squeeze Me consists of a soft rubbery interactive cover, that can be mounted on a tablet, to enable expression-rich communication. The cover embeds two specifically designed resistive analogue pressure sensors. The expressions exerted on the device by the person are mapped to movements of the robot as well as to an expressive mask displayed on the graphical user interface (GUI) of the tablet that is used to control the robot. This mask shows the robot's view on the environment as well as its internal states (feelings). A short pinch exercised by the person on the cover results in a sturdy movement of the robot. A hard squeeze results in a quick movement and a gentle touch in a slow approach. All changes in movement are mapped to the modifications in the expressions of the mask, e.g. from neutral to surprise, or joy, depending on the context of interaction. The paper describes the design and implementation of the Squeeze Me prototype, together with a scenario of use in the context of an older person - robot interaction
Not all sizes matter. The perception of robots' age and mental abilities based on their physical dimensions
Get PDFThe study analyses differences in the perception of age and mental
abilities of robots displayed as 3D models in an immersive VR
room (CAVE), manipulating anthropomorphic variables such as
height, head dimension, and limb length. Participants (N = 122)
were randomly assigned to one of four experimental conditions
where they interacted with a robot with a different combination
of physical dimensions. After the interaction, participants had to
fill in a post-test questionnaire where they were assessed for their
tendency to anthropomorphise and their AI knowledge.
The results show that different combinations of physical appearance of the robots affect the perception of their age. In particular,
the combination of robot size and parts dimension influences age
perception but not the mental characteristics of the robots. These
results might have implication for developing robots for specific
functions, such child care or support in study activities
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Antioxidants, Dietary Fatty Acids, and Sperm: A Virtual Reality Applied Game for Scientific Dissemination
Get PDFFatty acid (FA) profile appears to be critical to infertility, and the effects of dietary FAs on sperm FA content are a current focus of studies in the field of nutrition and reproduction. Starting from a validated “OXISTRESS” model in which modification of FA content results to influence reactive oxygen species, antioxidants, isoprostanes, cytokines, sperm kinetic, and acrosome reaction, we developed a virtual reality game where the player, in order to improve the health of some virtual spermatozoa, is called to take dietary choices and then discover their consequences on the main biological aspects. In the LabVR of the University of Siena, a team of VR environment designer and developer used Unity development engine to make the experience run on Oculus Quest and a wireless 6DOF (six degrees of freedom of movement in 3D space) VR Headset. In the game, the player is immersed in the epididymis and observes closer how dietary n-3 may change the sperm plasma membrane and consequently modify sperm traits. A simulation game in the virtual reality may represent a tool to give greater visibility to scientific data in the relevance of appropriate dietary habits in the human health
