The night has been the subject of multiple readings by the social and human sciences, as well as it has inspired multiple narratives throughout history, literature and popular culture. However, the study of nightlife, practices, and actors only gained attention in recent years. The appearance of “mayors of the night” with the intention of improving urban governance during this period and thus guaranteeing needs, rights and services is the result of a progressive change in the local political paradigm, which begins to face this space-time as a “new” opportunity for its economic, social and cultural development. We could say that the night and the activities that take place in it begin to be projected as forms of tourist attraction, whether for their leisure activities such as discos, parties or other forms of fun; or because of its cultural potential, such as the White Nights. Contemporary urban night implies having active professionals, capable of reacting to any incident, such as the case of health professionals, but also maintaining those professions – often illegal – that tend to be considered problematic or hidden as could be prostitution. Surveillance and control during this period is also a good example of active professions, such as the case of the police, surveillance companies, video-doorman, or firefighters. It has never been so easy to commute in the urban space, public transport normally meets the needs of users, and the emergence of new forms of transport resulting from the circular economy, both of people and goods, completes the demand, not without controversy. There are many different ways to approach the night, but here we collect some of the communications that participated during the I International Conference on Night Studies, that took place on-line, due to the COVID-19 pandemic, on July 2 -4, 2020. These communications are also on-line on the official account of the conference.info:eu-repo/semantics/publishedVersio

Tourism, nightlife and planning: challenges and opportunities for community liveability in La Barceloneta

In La Barceloneta, one of the beachfront quarters of the city of Barcelona, the rapid expansion of mainly illegal short-term rental apartments for tourists and noise problems related to alcohol-fuelled nightlife consumption, are challenging community liveability and peaceful urban coexistence between different social groups. Similar to other cases worldwide, the rapid expansion of touristification on the urban and socio-economic fabric of the city has become an increasing source of dispute and residents' contestation. By taking a diachronical critical review, the first part of this paper examines the role of urban planning developed in La Barceloneta during the period 1950–2016 and how it transformed the area into a leisure-oriented and tourist-oriented quarter. The second part of the paper is based on two years of ethnographic fieldwork that was conducted to capture the range of different voices, stories and discourses produced and reproduced by different actors affected and/or involved in the recent touristification of La Barceloneta. Findings obtained confirm that current urban policy and planning are clearly insufficient to tackle and address negative community-based impacts aforementioned. Hence, the final section highlights the urgent need for the development and implementation of new, community-based urban planning with the aim of ensuring community liveability and peaceful urban coexistence between different social groups in La Barceloneta

Evolution of the Sweetness Receptor in Primates. II. Gustatory Responses of Non-human Primates to Nine Compounds Known to be Sweet in Man

The gustatory responses of nine compounds, namely glycine, D-phenylalanine, D-tryptophan, cyanosuosan, magapame, sucrononate, campame, cyclamate and superaspartame, all known as sweet in man, were studied in 41 species or subspecies of non-human primates, selected among Prosimii (Lemuridae and Lorisidae), Platyrrhini (Callitrichidae and Cebidae) and Catarrhini (Cercopithecidae, Hylobatidae and Pongidae). The first six compounds are generally sweet to all primates, which implies that they interact with the primate sweetness receptors essentially through constant recognition sites. Campame is sweet only to Cebidae and Catarrhini, cyclamate only to Catarrhini, superaspartame principally to Callitrichidae and Catarrhini, which implies that all these compounds interact with the receptors partly through variable recognition sites. From the present work, from other previous results (where notably it was observed that alitame is sweet to all primates, ampame only to Prosimii and Catarrhini, and aspartame only to Catarrhini), and from the multipoint attachment (MPA) theory of sweetness reception (as elaborated by Nofre and Tinti from a detailed study of structure-activity relationships of various sweeteners in man), it is inferred that the primate sweetness receptors are very likely made up of eight recognition sites, of which the first, second, third, fourth, seventh and eighth are constant, and the fifth and sixth variable. From these results and from the MPA theory, it is also inferred that the recognition sites of the primate sweetness receptors could be: Asp-1 or Glu-1, Lys-2, Asp-3 or Glu-3, Thr-4, X-5, X-6, Thr-7, Ser-8, where the variable recognition sites X-5 and X-6 would be: Ala-5 and Ala-6 for Callitrichidae, Ser-5 and Ala-6 for Cebidae, Ala-5 and Thr-6 for Prosimii, and Thr-5 and Thr-6 for Catarrhini. By using Tupaiidae (tree shrews) as a reference outgroup and by means of other structural and functional molecular considerations, it appears that Callitrichidae have retained the most primitive receptor among the four types of primate receptors. The possible taxonomic and phylogenetic implications of these findings are discussed. Chem. Senses 21: 747-762, 199

Nighttime leisure and youth resistance in (post-)pandemic times: The case of young people from the Antù bar in Lisbon

Em Lisboa, desde o primeiro verão pandêmico, observamos o surgimento de novos atores informais na noite turística do antigo bairro portuário do Cais do Sodré que desenvolviam práticas alternativas de lazer com algumas particularidades: são jovens de nível socioeconômico precário, apresentam traços culturais alternativos e concentram-se para socializar e consumir álcool no espaço público em frente ao bar Antù. Esses jovens são vistos pelas autoridades públicas e por seu braço repressivo policial como atores “indesejáveis” à “normalidade” da noite turística do Cais do Sodré. A sua “alteridade” (ligada a cor de pele, estética corporal e classe social) constitui-se como um elemento perturbador na noite turística da Pink Street. Essa área de diversão noturna tem uma natureza marcadamente hedonista e orientada quase exclusivamente para indivíduos brancos (lisboetas ou não) de classe média alta. Este artigo, resultante de um enfoque etnográfico, visa a analisar a dialética desigual entre a repressão policial (por vezes, violenta) e a resistência performativa dos atores “indesejáveis” da noite turística do Cais do Sodré. O artigo argumenta que os espaços em causa – o bar Antù e o espaço público situado ao redor do estabelecimento – não só emergem como palcos de uma forma de resistência performativa e recusa dos valores societais capitalistas, mas também como um local que proporciona alternativas de (de)construção comunitária e coesão social dentro de um contexto pós-pandêmico profundamente criminalizado, racializado e punitivo.info:eu-repo/semantics/publishedVersio

Strangers in the night: nightlife studies and new urban tourism

This paper draws together recent scholarship from the study of urban tourism and nightlife. Though studies of urban tourism do not always specifically address nightlife, and likewise studies of the night and nightlife do not always examine tourism, both bodies of research overlap in important ways. Concerns about commercialisation, gentrification, displacement, and urban change are to be found in both bodies of research. However, while the study of urban tourism typically recognises the erasure of the host / guest binary and seeks to destabilise the notion of who is a tourist or stranger, studies of nightlife often rest on a much clearer distinction between who belongs and who does not. An argument proposed here is that while the host / guest, tourist / non-tourist binary is perhaps reconfiguring, the night and nightlife spaces reinstate these binaries in various ways. This paper thinks through debates about tourists and residents in the night, focusing in particular on questions of belonging, place identification and gentrification through night-time uses

Assessing learning and memory in pigs

In recent years, there has been a surge of interest in (mini) pigs (Sus scrofa) as species for cognitive research. A major reason for this is their physiological and anatomical similarity with humans. For example, pigs possess a well-developed, large brain. Assessment of the learning and memory functions of pigs is not only relevant to human research but also to animal welfare, given the nature of current farming practices and the demands they make on animal health and behavior. In this article, we review studies of pig cognition, focusing on the underlying processes and mechanisms, with a view to identifying. Our goal is to aid the selection of appropriate cognitive tasks for research into pig cognition. To this end, we formulated several basic criteria for pig cognition tests and then applied these criteria and knowledge about pig-specific sensorimotor abilities and behavior to evaluate the merits, drawbacks, and limitations of the different types of tests used to date. While behavioral studies using (mini) pigs have shown that this species can perform learning and memory tasks, and much has been learned about pig cognition, results have not been replicated or proven replicable because of the lack of validated, translational behavioral paradigms that are specially suited to tap specific aspects of pig cognition. We identified several promising types of tasks for use in studies of pig cognition, such as versatile spatial free-choice type tasks that allow the simultaneous measurement of several behavioral domains. The use of appropriate tasks will facilitate the collection of reliable and valid data on pig cognition
