Our ability to acknowledge and recognize our own identity — our “self” — is a characteristic doubtless unique to humans. Where does this feeling come from? How does the combination of ...neurophysiological processes coupled with our interaction with the outside world construct this coherent identity? We know that our social interactions contribute via the eyes, ears, etc. However, our self is not only influenced by our senses. It is also influenced by the actions we perform and those we see others perform. Our brain anticipates the effects of our own actions and simulates the actions of others. In this way, we become able to understand ourselves and to understand the actions and emotions of others. This book describes the new field of “Motor Cognition”. Though motor actions have long been studied by neuroscientists and physiologists, it is only recently that scientists have considered the role of actions in building the self. How consciousness of action is part of self-consciousness, how one's own actions determine the sense of being an agent, how actions performed by others impact on ourselves for understanding others, differentiating ourselves from them and learning from them: these questions are raised and discussed throughout the book, drawing on experimental, clinical, and theoretical bases. The advent of new neuroscience techniques, such as neuroimaging and direct electrical brain stimulation, together with a renewal of behavioral methods in cognitive psychology, provide new insights into this area. Mental imagery of action, self-recognition, consciousness of actions, imitation can be objectively studied using these new tools. The results of these investigations shed light on clinical disorders in neurology, psychiatry, and in neuro-development.
This paper compares the performance of a vertical-finned microchannel heat exchanger (VMHX) and a 2-row fin-tube heat exchanger (FTHX) under wet and frosting conditions. The VMHX features vertically ...oriented fins with an extension at the windward side and parallel microchannel tubes, allowing for efficient water drainage and better performance than conventional microchannel heat exchangers with parallel serpentine fins. However, the performance of the VMHX has not been sufficiently compared to that of FTHX. After conducting experiments under specific operating conditions, the VMHX exhibits better water drainage performance than the FTHX at higher inlet air velocities, higher maximum heat flow, and time-integrating heat flow under certain operating conditions. Although the heating time is relatively shorter than the 2-row FTHX, these results suggest that the VMHX may be a more suitable option for applications requiring efficient water drainage and heat transfer. Additionally, the operating conditions significantly affect the heat exchanger's performance. The performance of VMHX is analyzed under different inlet air velocities, inlet air temperatures, and evaporation temperatures. The results indicate that frost itself had no effect on the heat exchanger performance and that the decrease of the inlet air flow rate was the main factor that decreased the heat exchanger performance. Overall, the results of this study provide valuable insights into the performance of VMHX and FTHX under wet and frosting conditions and the impact of various operating parameters on VMHX performance. These findings can inform the development of more efficient and reliable heat exchangers for various applications.
Selection of the HPLC Method in Chemical Analysis serves as a practical guide to users of high-performance liquid chromatography and provides criteria for method selection, development, and ...validation. High-performance liquid chromatography (HPLC) is the most common analytical technique currently practiced in chemistry. However, the process of finding the appropriate information for a particular analytical project requires significant effort and pre-existent knowledge in the field. Further, sorting through the wealth of published data and literature takes both time and effort away from the critical aspects of HPLC method selection. For the first time, a systematic approach for sorting through the available information and reviewing critically the up-to-date progress in HPLC for selecting a specific analysis is available in a single book. Selection of the HPLC Method in Chemical Analysis is an inclusive go-to reference for HPLC method selection, development, and validation. * Addresses the various aspects of practice and instrumentation needed to obtain reliable HPLC analysis results * Leads researchers to the best choice of an HPLC method from the overabundance of information existent in the field * Provides criteria for HPLC method selection, development, and validation * Authored by world-renowned HPLC experts who have more than 60 years of combined experience in the field
Este texto se estrutura como uma interface entre as áreas de Performance e de Educação Musical. O seu objetivo é apresentar a ideia de Performances com Musicares enquanto Performances de Existência. ...A ideia de musicar faz referência à concepção de Christopher Small (1999). O texto faz parte de uma pesquisa de Doutorado em andamento que se realiza por meio da etnografia, a autoetnografia e a cartografia como métodos de trabalho. A investigação contou com a pesquisa de campo, sendo realizadas entrevistas on-line com doze professores de violoncelo de oito espaços musicais de ensino e aprendizagem de estudantes iniciantes no Brasil. Entre os resultados apontados pela investigação, se incluem a ideia de que as performances se estruturam sobre contextos sobrepostos e dialógicos. Como reflexões, a pesquisa aponta que as performances com práticas musicais podem ser interpretadas como processos pedagógicos de representação de formas de existir que se ampliam à vida cotidiana.
•Strong relationship between digitalization, sustainability and performance.•Positive results under the environmental and social lens push economic performance.•The size impacts on both financial and ...sustainable performance.•Digitalization for sustainability creates new opportunities.
Environmental and social issues have become increasingly important both at operating and strategic levels. Enterprises must integrate sustainability within their strategies. This implementation should be supported by different managerial tools and digital technologies. The latter is central in supporting sustainability implementation and conversion, and therefore, the interaction between digitalization and sustainability can unlock higher potential. Consequently, this study mainly aimed to understand the link between digitalization, sustainability, and performance in the Italian context. Our findings reveal a significant relationship between digitalization, sustainability, and profitability performance and that when positive results are achieved under the environmental and social lens, economic performance also improves. Our study highlights the role of enterprise size and its impact on financial and sustainable performance, thus addressing the gaps in the literature.
Many behaviors require that individuals coordinate the timing of their actions with others. The current study investigated the role of two factors in temporal coordination of joint music performance: ...differences in partners’ spontaneous (uncued) rate and auditory feedback generated by oneself and one’s partner. Pianists performed melodies independently (in a Solo condition), and with a partner (in a duet condition), either at the same time as a partner (Unison), or at a temporal offset (Round), such that pianists heard their partner produce a serially shifted copy of their own sequence. Access to self-produced auditory information during duet performance was manipulated as well: Performers heard either full auditory feedback (Full), or only feedback from their partner (Other). Larger differences in partners’ spontaneous rates of Solo performances were associated with larger asynchronies (less effective synchronization) during duet performance. Auditory feedback also influenced temporal coordination of duet performance: Pianists were more coordinated (smaller tone onset asynchronies and more mutual adaptation) during duet performances when self-generated auditory feedback aligned with partner-generated feedback (Unison) than when it did not (Round). Removal of self-feedback disrupted coordination (larger tone onset asynchronies) during Round performances only. Together, findings suggest that differences in partners’ spontaneous rates of Solo performances, as well as differences in self- and partner-generated auditory feedback, influence temporal coordination of joint sensorimotor behaviors.
John Cage is best known for his indeterminate music, which leaves a significant level of creative decision-making in the hands of the performer. But how much licence did Cage allow? Martin Iddon's ...book is the first volume to collect the complete extant correspondence between the composer and pianist David Tudor, one of Cage's most provocative and significant musical collaborators. The book presents their partnership from working together in New York in the early 1950s, through periods on tour in Europe, until the late stages of their work from the 1960s onwards, carried out almost exclusively within the frame of the Merce Cunningham Dance Company. Tackling the question of how much creative flexibility Tudor was granted, Iddon includes detailed examples of the ways in which Tudor realised Cage's work, especially focusing on Music of Changes to Variations II, to show how composer and pianist influenced one another's methods and styles.
The article deals with the phenomenon of mythologizing the activity of buskers. The purpose of the paper is to demonstrate that street performers, despite their rich and varied history, both ...diachronically and synchronically, continue to be represented in a simplistic, stereotypical way. The intention of the authors was to show the real, more complex image and identity of buskers. The research problem concerns the mythologization of street performances in terms of discourse, self-narration, and self-creation. The article relates to three research questions: (1) How are the activity of buskers and the performers themselves being described? (2) How do buskers create and explain their own stories in terms of performing in the street? (3) How do they create and interpret their image? The article is the result of a joint analysis of the outcomes of ethnographic fieldworks conducted independently by two researchers in 2011–2019 in various cities, mainly in Poland but also abroad. The results show that the activity of buskers is subject to mythologization, which impacts the discourse on their activity as well as the formation of their identity and image.
