Although it is widely accepted that robots will be used in everyday contexts in near future, many people feel anxious and hold negative attitudes toward robots. This negative reaction might be stronger when users come into direct physical contact with them, particularly when touch is required between robots and humans, (e.g., when using robots as assistants to help elderly people at home). Intergroup contact research in social psychology has proposed various forms of contact as a means to reduce negative feelings toward outgroup members. The present study examined how Contact Type (Actual vs. Imagined) and Contact Modality (Look vs. Touch) with a NAO robot would impact attitudes toward NAO compared to a no-contact control condition. Results showed that nearly any type of contact effectively reduced negative emotions compared to the control condition. However, for participants with preexisting negative emotions toward robots, contact sometimes produced more negative attitudes. We discuss these findings and the resulting implications for future research.

This paper investigates whether empathy towards an interactive trash bin, particularly empathy induced by the bin's anthropomorphic appearance and behavior, affects people's evaluations of the artifact and their intention to use it to recycle. We performed an online survey in which 344 participants viewed a video showing a person interacting with a recycling bin in one of three conditions: non-interactive/control, non-anthropomorphic interactive, and anthropomorphic interactive. We measured people's perceptions of the bin's anthropomorphism and animacy, their empathy and anxiety towards and enjoyment of the bin, their perceptions of its sociability and usefulness, and finally their intentions to use the bin. The results suggest that the level of anthropomorphism attributed to the artifact by participants positively affected their empathy towards the recycling bin, which in turn directly influenced their intentions to use the bin.

Assistive robots designed to support independently living older adults are expected to solve diverse physical, social and mental challenges related to aging. This paper presents how older adults-the potential users of assistive robots-interpret robotic technologies in terms of their usefulness and fit in their everyday lives. We interviewed 7 older adults aged 57-72, showing them photos and videos of assistive robots designed with their age group in mind. Most participants saw the robots as potentially useful in general terms, yet also commented that “those robots are not for me.” An analysis of their discussion about the robots identified several aspects of robot design that participants found problematic, particularly negative representations of aging depicted in robot use scenarios. Participants saw issues related to aging as important daily problems, but did not appreciate the manner in which robotics was expected to address those issues. They were particularly sensitive to the dominance of stereotypes defining aging primarily in terms of disability in robotics discourse and design. Based on participant feedback, we suggest a broader understanding of the experience of aging as the basis for future assistive robot design for this population, and conclude by discussing related robot design possibilities.

Aim To investigate prevalence, antimicrobial susceptibility, molecular characteristics, and genetic relationship of AmpC- and/or extended spectrum beta lactamase (ESBL)- producing Proteus spp. clinical isolates in Zenica-Doboj Canton, Bosnia and Herzegovina. Methods Antibiotic susceptibility was determined by disc diffusion and broth microdilution methods according to CLSI guidelines. Double-disk synergy test was performed in order to screen for ESBLs, and combined disk test with phenylboronic acid to detect AmpC β -lactamases. PCR was used to detect blaESBL/blacarb genes. Genetic relatedness of the strains was determined by pulsed-fieldgel-electrophoresis (PFGE). Results Eleven ESBL-producing isolates were included in the study (six inpatients and five outpatients). Susceptibility rate to amoxicillin-clavulanic acid, imipenem and meropenem was 100%. Resistance rate to cefuroxime was 100%, gentamicine 90.9%, piperacillin/tazobactam 81.8%, cefotaxim, ceftriaxone and ceftazidime 72.7%, cefoxitine and ciprofloxacine 63.6% and to cefepime 45.5%. In five (out of 11) isolates multi-drug resistance (MDR) to cephalosporins, cefamicines, amynocligosides and fluoroquinolones was detected. Besides TEM-1 which was detected in all isolates, CTX-M+OXA-1 β-lactamases were detected in seven (out of 11; 63.6%) isolates (five blaCTX-M-1 and two blaCTX-M-15 genes), and CMY-2 β-lactamase in two isolates. PFGE showed no genetic relatedness. Conclusion Because of high prevalence of MDR strains in epidemiologically unrelated patients with AmpC- and/or ESBL producing Proteus spp. infection, further surveillance is needed. Molecular characterization and strain typing, or at least phenotypic test for AmpC/ESBL production is important for appropriate therapy and the detection of sources and modes of spread, which is the main step in order to design targeted infection control strategies.

Aim To examine the presence of morphologic variations of occipital sulci patternsin patients with schizophrenia and migraine headacheregarding gender and laterality using magnetic resonance imaging (MRI). Methods This study included 80 patients and brain scans were performed to analyze interhemispheric symmetry and the sulcal patterns of the occipital region of both hemispheres. Average total volumes of both hemispheres of the healthy population were used for comparison. Results There was statistically significant difference between subjects considering gender (p=0.012)with no difference regarding age(p=0.1821). Parameters of parieto-occipital fissure (p=0.0314), body of the calcarine sulcus (p=0.0213), inferior sagittal sulcus (p=0.0443), and lateral occipital sulcus (p=0.0411) showed statistically significant difference only of left hemisphere in male patients with schizophrenia with shallowerdepth of the sulcus. Conclusion Representation of neuroanatomical structures suggests the existence of structural neuroanatomic disorders with focal brain changes. Comparative analysis of occipital lobe and their morphologic structures (cortical dysmorphology) in patients with schizophreniausing MRI, according to genderindicates a significant cortical reduction in the left hemisphere only in the group of male patients compared to female patients and the control group.
