In Lisbon, the fairs and their amusements were one of the most popular manifestations of popular culture during the second half of the 19th century and the beginning of the 20th century. Among the ...entertainment on offer, theater was one of the most appreciated, but history has only kept the memory of the shacks that, in the fairs, began to feature a recited repertoire (comedies, parodies, magic and revues). The tents of harlequins and saltimbancos, itinerant troupes that went from place-toplace performing acrobatics, pantomimes, and comic sketches, were forgotten. This article aims to highlight popular theater practices that were once ‘forgotten’, such as the troupes of harlequins and their shows, redefining their importance in the context of the time and the history of theater in Portugal.
Virtual Reality (VR) has sparked interest within the forensic community, where it is currently used for training purposes and in variety of forensic scenarios. In combination with efficient and user ...friendly full body 3-Dimensional (3D) documentation methods, VR visualisations present a viable tool for suspect witness identification. The well-known procedure of placing several persons in a room with a one-way-mirror, along with a witness on the other side of the mirror has practical disadvantages. The primary concern implicates the witness(s) and person(s) of interest coming face-to-face prior to the line-up, combined with finding sufficient persons to include within the line-up. Although image identification using printed paper partially resolved this problem, features such as body stature also marks an issue for the recognition and identification process.
To test whether VR provides the technical capabilities to perform an identification parade, a total of 15 subjects were 3D documented using the multi-camera device “Photobox”. From this group, one of the documented persons then interrupted a lecture, where consequently, the students were asked afterwards to identify the same person in VR and paper identification sets. It was found that the participating students were able to identify the “suspect” in both datasets. The results imply that VR technology allow users to identify persons. However, as this is a preliminary study the similarity problem was not analysed in this paper and requires further investigation to demonstrate the robustness of this approach.
•Virtual Reality presents a novel approach for identification parades.•Virtual Reality identification parades require 3D documentation of suspect and other people in the line-up.•A technical set-up for identification parades in virtual reality is feasible.
The measurement of PM2.5 was conducted from 20th October to 25th November 2014, and 15th August to 15th September 2015 at Beijing, Shijiazhuang, and Tangshan, China, covering two important events of ...Asia-Pacific Economic Cooperation (APEC) and Grand Military Parade (Parade). A series of stringent emission-reduction measures were implemented in Beijing and neighbouring regions to ensure good air quality in Beijing. PM2.5 concentrations and major components (water-soluble ions and carbonaceous aerosol) were analyzed and compared between the two events. PM2.5 concentration during control demonstrated a decreasing trend with 51.6%–65.1% and 34.2%–64.7% compared to no control during APEC and Parade, respectively. The water-soluble ions and carbonaceous aerosol concentrations also decreased obviously. The lower secondary inorganic ions (SIA, including SO42−, NO3−, and NH4+) percentage (31.7%–38.3%) during control indicated the relative weak contribution of atmospheric chemical processes. Due to the unfavorable weather conditions and increased emissions during coal-fired heating, the relative higher organic carbon (OC), secondary organic carbon (SOC), secondary organic aerosol (SOA) concentrations during APEC was found. The WRF-CMAQ modeling system was also used to quantify the effect of emission-reduction and different sources controls on PM2.5. The results indicated PM2.5 decrease by 30.4% and 34.2% under control during APEC and Parade, respectively. We found that the local emission-reduction in Beijing contributes more to “APEC blue” (20.8%) and “Parade blue” (25.8%) in Beijing than those from neighbouring regions of Beijing, and meteorological condition was more beneficial for the improvement of the air quality during Parade than APEC. The emission source apportionment to PM2.5 in Beijing indicated that PM2.5 concentration increased by 13.5% and 14.7% during APEC and Parade, respectively if no vehicles emission-reduction measures were taken in Beijing.

Unfamiliar voice identification is error-prone. Whilst the investigation of system variables may indicate ways of boosting earwitness performance, this is an under-researched area. Two experiments ...were conducted to investigate how methods of presenting voices during a parade affect accuracy and self-rated confidence. In each experiment participants listened to a target voice, and were later asked to identify that voice from a nine-person target present or target absent parade. In Experiment 1, accuracy did not vary across parades comprising 15 or 30 s sample durations. Overall, when the target was present, participants correctly identified the target voice with 39% accuracy. However, when the target was absent, participants correctly rejected the parade 6% of the time. There was no relationship between accuracy and confidence. In Experiment 2, performance with a serial procedure, in which participants responded after hearing all nine voices, was compared with a sequential procedure, in which participants made a decision after listening to each voice. Overall accuracy was higher with the sequential procedure. These results highlight the importance of system variable research in voice identification. Different methods of presenting voices have the potential to support higher levels of accuracy than the procedure currently recommended in England and Wales.
Pride parades, serving as platforms for celebrating diverse sexual orientations and gender identities, often operate within a society that upholds and reinforces heteronormative norms. This ...commentary intends to argue how these activities are shaped by the presence of restrictions and censorship and the prevalence of ignorance surrounding queer experiences. By conducting ethnographic observations at Pride parades in Turkey and Spain, I delve into participants’ lived experiences within these contexts. This approach sheds light on Pride parades’ positive and negative aspects. Through an analysis of the interplay between heteronormative influences, restrictions, censorship, and ignorance within the context of Pride parades, I aim to provide insight into the complexities and nuances that shape the experiences of queer individuals. This commentary contributes to a deeper understanding of the challenges faced and the progress made in the ongoing struggle for queer liberation and acceptance.
Cet article à valeur épistémologique vise à examiner le « faire récit » de la lanterne dans une approche matérialiste et performative. Il s’agit de dégager les « terrains » où s’exprime la ...narrativité de la lanterne et de porter attention à la marge d’indétermination (Simondon) du dispositif renvoyant à un vaste éventail de gestes techniques et expressifs que l’on pourrait associer à des technèmes. Parmi ces différents gestes expressifs, une attention particulière sera portée au geste qui consiste à faire défiler les images. Celui-ci nous semble disposer d’un potentiel narratif plus marqué que d’autres dans le sens où il s’articule directement à certaines capacités techniques de base de la lanterne pour tirer profit de sa narrativité latente.
Based on ozone observation data from urban stations and the Dingling (DL) background station, we investigated the trend of ozone concentrations in Beijing during 2004–2015. For urban stations, both ...O3_1 h and O3_8 h increased stably with a clear and significant linear pattern and the increase rate was notably higher during the period of May to Sep. Meanwhile, the variation of O3_1 h and O3_8 h for the DL station did not demonstrate a regular pattern. During this period, the differences between the diurnal peak of ozone concentrations at the DL background station and urban stations decreased significantly due to the rapid urbanization of Beijing. Furthermore, we examined simultaneous variations of ozone and its precursors during 2015 Grand Military Parade and 2014 APEC meeting and evaluated the performances of different emission-reduction measures during the two specific events. For 2015 Grand Military Parade, emission-reduction measures were implemented 14 days in advance, which led to a notable decrease of ozone concentrations during the Parade period. For 2014 APEC meeting, emission-reduction measures were not implemented in advance, which led to incomplete VOCs reduction and high VOCs/NOx values, and thus a significant increase of ozone concentrations during the APEC period. The emission-reduction measures during APEC and PARADE periods both slowed down the accumulation and cut down the concentration peaks of ozone. We also analyzed simultaneous concentration variations of ozone and its precursors in long time-series. The results proved that compared with other precursors, NO2/NO was an effective indicator for ozone concentration in Beijing, especially in urban areas. The findings from this research provide useful reference for better monitoring and managing ozone concentrations in Beijing and other cities through properly designed and implemented emission-reduction measures.
