Standstill behavior by a robot is deemed to be ineffective and inefficient to convey a robot’s intention to yield priority to another party in spatial interaction. Instead, robots could convey their intention and, thus, their next action via motion. We developed a back-off movement to communicate the intention of yielding priority to pedestrians at bottlenecks. To evaluate human sensory perception and subjective legibility, the back-off is compared to three other motion strategies in a video study with N = 167 interviewees at the university and public spaces, where it excels regarding legibility. Implemented in a real encounter, objective motion behavior of N = 78 participants as a reaction to a stop & wait strategy, and two versions of back-off (short and long) shows an improvement of the pedestrians’ efficiency in the second encounter with the robot’s short back-off version compared to the stop strategy. Eventually, in the third encounter with all motion strategies, interaction causes only a small time consumption still required by the cognitive process of perceiving an object in the visual field. Hence, the design of kinematic parameters, back-off path and time, exhibits the potential to increase the fluency of an interaction with robots at bottlenecks.

Standstill behavior by a robot is deemed to be ineffective and inefficient to convey a robot’s intention to yield priority to another party in spatial interaction. Instead, robots could convey their intention and thus their next action via motion. We developed a back-off (BO) movement to communicate the intention of yielding priority to pedestrians at bottlenecks. To evaluate human sensory perception and subjective legibility, the BO is compared to three other motion strategies in a video study with 167 interviewees at the university and public spaces, where it excels regarding legibility. Implemented in a real encounter, objective motion behavior of 78 participants as a reaction to a stop-and-wait strategy, and two versions of BO (short and long), shows an improvement of the pedestrians’ efficiency in the second encounter with the robot’s short BO version compared to the stop strategy. Eventually, in the third encounter with all motion strategies, interaction causes only a small time consumption still required by the cognitive process of perceiving an object in the visual field. Hence, the design of kinematic parameters, BO path and time, exhibits the potential to increase the fluency of an interaction with robots at bottlenecks.

YOU CAN’T TALK ABOUT DAS BECKWERK; YOU ARE ALREADY IN DAS BECKWERK | Subjected to a one-year ban on performances in the public spaces of Scandinavia, the former CEO of the Copenhagen-based enterprise Das Beckwerk held a lecture on 9th December 2011 solely for the ears of the rising star of fictionality and narratology Richard Walsh from the University of York. The lecture dealt not only with the disappearing boundaries betweenreality and fiction but also with how novel characters have become legal citizens, while the author is turned into fiction. Finally the former CEO dismisses the judgment in the famous trial “Thomas Skade-Rasmussen Strøbech versus Gyldendal and Helge Bille Nielsen”. He calls it unjust and a neglect of the fictional character’s right to a personal name, story and picture.

Street Art deTours (streetartdetours.com) is a crowd-sourced, locative art project that uses ‘detours’ – creative stories and experiments – to find imaginative ways to experience public spaces. Primarily relying upon street art in Melbourne as a point of access, the project was the final assessment in a street art subject taught at the University of Melbourne. This paper outlines the implications of that project, and it references those detours contributed by students to argue in favor of playful participation’s academic benefits. Identifying street art’s encounter as a cinematic event that is simultaneously imaginative and personal, the paper posits audience empowerment as crucial to the study of street art. It concludes that the practice’s subjectivity, in addition to the performative aspects of its experience, necessitates street art’s creative engagement.

The purpose of this study is to find out how the information age community understands digital public space and how the role of the University of Lampung's digital library in creating virtual public spaces. This research uses descriptive qualitative research methods. This research builds on the critical theory of public space proposed by Jurgen Habermas and Henry Lefebvre. Data collection through literature study and interviews. Data analysis includes three stages namely data reduction, data presentation, and conclusion or verification. Based on the results of the study, it was found that the public space in the information society is interpreted as a space where there is an infinite process of interaction. The role of the University of Lampung's digital library in creating public spaces includes (1) Providing freedom of access to systems and content, (2) giving freedom of expression to users through communication facilities between users and managers (3) Providing equality for anyone to access and utilize digital library applications The University of Lampung (4) has a legal umbrella in managing digital libraries (5) has a shared commitment to turn the University of Lampung's digital library into an ideal public space. Keywords: Digital Library, Public Spaces, Information Society.

The article aims to assess the quality of public spaces of the Third Campus of the Jagiellonian University and to determine to what extent the mobile crowdsensing survey method is useful in this respect. Public spaces are nowadays considered the key elements of the university campus structure. Their appropriate shaping and management fosters social interactions between different user groups, which should consequently strengthen creativity and interdisciplinarity within the university milieu. Our paper presents contemporary trends in the campus planning and organisation. In the empirical part, the quality of selected public spaces (main avenue, squares and courtyards, and green areas) was determined based on the behaviour of campus users as observed by participants of the crowdsensing study. These results were confronted with the visual material and comments of the study participants, as well as with the expert assessment of the authors. In the final part, activities aimed at improving the quality of public spaces of the campus were proposed.

Luz Marina García Herrera, professor at the University of La Laguna, colleague, teacher and friend, passed away in June 2020. A reference in Spanish Urban Geography, her contribution to the debate on the shaping of the city and the social dynamics inherent to it has opened up timely and necessary lines of work. She anchors her background in the interpretation of urban social processes under capitalism, focusing on key issues such as marginal developments, gentrification mechanisms or different facets of urban segregation. In addition she also approaches other issues in which we have been able to share time and space with her. Among them the constant and changing conditioning between physical and social environments in the city and consequences, or the reading of public spaces, their use and appropriation keys, as an indicator of cohesion as well as an instrument for the transformation of specific realities. All of this, and even more his commitment and his profound humanity, which we are proud to have learned from, motivate these lines.

PurposeThe purposes of this research were to review, analyze, synthesize and define the principles, indicators and required design elements of crime prevention through environmental design (CPTED) and the potential role of the design of the courtyards in preventing campus violence; to examine the relationships between built environment design and campus violence inside Al al-Bayt University (AABU), Jordan; and to examine to what extent the design of the open public spaces and courtyards inside AABU meet the design principles of the CPTED.Design/methodology/approachThis research used descriptive-analytical approach, semi-structured interviews, archival records and videos to collect the location-based data of violent events and incidents that occurred on the campus of AABU (the locations of students' fights). Additionally, this research used AABU images; plans, spatial analysis, site visits and direct observations to analyze and assess the courtyards’ design and to examine to what extent the design of courtyards and open public spaces in AABU achieve the CPTED indicators, and the availability and the quality of the required design elements of CPTED and their role in violence prevention.FindingsThis research found that environmental-based design plays a major role in reducing crime opportunities and promote positive social behavior. This research found that the indicators to achieve the CPTED principles in all courtyard design inside AABU are very low and all the courtyards’ designs are not complied and conformed to the CPTED principles, and as a result, the design of the courtyards encourages and may facilitate violence in the university campus. It has been found that the availability and the quality of the required CPTED design elements are very low in all courtyards. Therefore, the existing design elements in all courtyards in AABU are not preventing the university violence. The correlation result revealed that there is significant relationship and strong/very strong negative linear association between the numbers of the students' fights and the applying of CPTED principles, indicators and required design elements (r = −0.85).Research limitations/implicationsThe data collected from AABU campus only and a larger study is certainly required to underpin these findings. Therefore, future research is needed to replicate and duplicate this research in order to expand the results.Practical implicationsThis research has implications for designing/redesigning the open public space and courtyards inside universities. This research recommended that redesigning all courtyards and applying the principles of CPTED are necessary to prevent campus violence. Redesigning includes adding landscaping elements, fountains, water features, pedestrian furniture, portrait, setting areas, new modern sculptures, shaded areas, lighting, memorial places, digital screens and cameras. Moreover, this research recommended that the university should pay more attention to continuous control, repair and maintenance to all courtyards after redesigning them. Finally, this research introduced a design proposal for one of the courtyards to apply the CPTED principles that promote positive behavior and prevent campus violence.Originality/valueIn the last few years in Jordan, some of the public and private Jordanian universities suffered from a newly emerging negative phenomenon, which is violence between students inside the campus. Many researchers and governmental institutions have stressed the urgency to explore the social, cultural, behavioral and environmental strategies that may effectively prevent campus violence. Additionally, little attention has been paid to the role of built environmental design in preventing campus violence. Moreover, no research assesses the applying of the CPTED principles and their indicators in courtyards’ design in Jordanian campuses.

The paper reveals a new dimension of implementing the third mission of a university - through the activities rolled-out by Russian universities in their botanic gardens. For urban residents, botanic gardens, in addition to their main functions, are gradually becoming a place for integrating different population groups, from schoolchildren to pensioners. These public spaces conduct active educational policies aimed at many segments of a broader university community, taking into account the experience of regional environmental organizations and international Associations of Botanic Gardens. The author argues that the ecological vector is a priority for productive communication of a university with regional and global audiences at the site of its Botanic Garden, which becomes a measure of the university entering upon the way of sustainable development
