Reviving the lost spaces under urban highways and bridges: an empirical study
No full textPurpose: The fast development of urban movement infrastructures has created neglected urban places in cities. This study aims to provide users’ preferences for designing lost spaces that are a by-product of elevated urban highways (UHs) and bridges to develop a conceptual model for better environmental design. Design/methodology/approach: This research is conducted by a combination of both qualitative and quantitative methods. In the first phase, to explore the citizen’s environmental preferences based on the Q-sort technique and in-depth interviews, the ideas of 50 users were considered up to data saturation. The preferences of people for designs under urban bridges were extracted by content analysis in the qualitative phase. In the quantitative phase, to validate these preferences, the extracted themes and sub-themes were examined by 144 experts in design studies using the web-based questionnaire based on the first phase outcomes. The validity of the model was confirmed by confirmatory factor analysis in SPSS22 and Lisrel software. Findings: The findings show that users’ preferences emphasize design strategies such as safety and security, physical coherence, visibility, vitality, richness, a sense of belonging and comfort to the design of lost spaces. Overall, this study highlights an empirical study into user’s needs and expectations of lost urban spaces. Originality/value: The findings show that users’ preferences emphasize design strategies such as safety and security, physical coherence, visibility, vitality, richness, a sense of belonging and comfort to the design of lost spaces.

Correlated physiological and perceptual effects of noise in a tactile stimulus
No full textWe investigated connections between the physiology of rat barrel cortex neurons and the sensation of vibration in humans. One set of experiments measured neuronal responses in anesthetized rats to trains of whisker deflections, each train characterized either by
constant amplitude across all deflections or by variable amplitude (“amplitude noise”). Firing rate and firing synchronywere, on aver-
age, boosted by the presence of noise. However, neurons were not uniform in their responses to noise. Barrel cortex neurons have been categorized as regular-spiking units (putative excitatory neurons) and fast-spiking units (putative inhibitory neurons). Among
regular-spiking units, amplitude noise caused a higher firing rate and increased cross-neuron synchrony. Among fast-spiking units, noise had the opposite effect: It led to a lower firing rate and decreased cross-neuron synchrony. This finding suggests that amplitude noise affects the interaction between inhibitory and excitatory neurons. From these physiological effects, we expected that noise would lead to an increase in the perceived intensity of a
vibration. We tested this notion using psychophysical measurements in humans. As predicted, subjects overestimated the intensity of noisy vibrations. Thus the physiological mechanisms present in barrel cortex also appear to be at work in the human tactile system, where they affect vibration perception
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
