For the nineteenth century, music was commonly characterized as the “art of time,” and provided a particularly fertile medium for articulating concerns about the nature of time and the temporal experience of human life. This chapter examines some of the debates around music and time from the period, arranged thematically around a series of conceptual issues. These include the reasons proposed for the links between music and time, and the intimate connection between our subjective experience of time and music; the use of music as a poetic metaphor for the temporal course of history; its use by philosophers as an instrument for the explication of temporal conundrums; its alleged potential for overcoming time; its various forms of temporal signification across diverse genres; and the legacy of nineteenth-century thought on these topics today.

The right to fair trial is inherent in the concept of due process of law, which now forms part of Article 21 of Indian Constitution after the Maneka Gandhi judgement. Pertinently attached with the same comes the responsibility of the criminal system to treat victims with increased awareness and sensitivity. However, the established convention shows that in planning and developing administration of criminal justice, proper attention is not given to the victims of crime in achieving goals of criminal justice; the major cause of it being that a victim is heard only as a witness not as a victim. A credible response to the said issue has emerged in the form of victim impact statement (VIS) in the modern legal system across the world. With that being said, the researchers through this article try to deduce the need for incorporating a VIS in India through the various jurisprudential understandings of what it means to be a victim, including the gap between the subjective experience of the sufferer and the interpretation of the same by others, and what restorative justice would mean to heal a victim. Establishing upon the same premise of victim status, the researchers try to suggest that the introduction of VIS, with the primary purpose of it being a therapeutic tool and not an instrument of changing the course of justice, will serve to make us reconsider our contours of a ‘victim’.

Abstract Facing one’s own death and managing the fear of death are important existential issues, particularly in older populations. Although recent functional magnetic resonance imaging (fMRI) studies have investigated brain responses to death-related stimuli, none has examined whether this brain activation was specific to one’s own death or how it was related to dispositional fear of death. In this study, during fMRI, 34 elderly participants (aged, 60–72 years) were presented with either death-related or death-unrelated negative words and asked to evaluate the relevance of these words to the “self” or the “other.” The results showed that only the left supplementary motor area (SMA) was selectively activated during self-relevant judgments of death-related words. Regression analyses of the effect of fear of death on brain activation during death-related thoughts identified a significant negative linear correlation in the right supramarginal gyrus (SMG) and an inverted-U-shaped correlation in the posterior cingulate cortex (PCC) only during self-relevant judgments. Our results suggest potential involvement of the SMA in the existential aspect of thoughts of death. The distinct fear-of-death-dependent responses in the SMG and PCC may reflect fear-associated distancing of the physical self and the processing of death-related thoughts as a self-relevant future agenda, respectively.

Young psychoactive substance users in social precarity are vulnerable to a range of health and social issues. Time perspective is one aspect to consider in supporting change. This study draws on the views expressed by young adults to portray their subjective experience of time, how this perception evolves and its implications for their substance use and socio-occupational integration trajectories. The sample includes 23 young psychoactive substance users ( M = 24.65 years old; 83% male) in social precarity frequenting a community-based harm reduction centre. Thematic analysis of the interviews reveals the past to be synonymous with disappointment and disillusionment, but also a constructive force. Participants expressed their present-day material and human needs as well as their need for recognition and a sense of control over their own destiny. Their limited ability to project into the future was also discussed. Avenues on how support to this population might be adapted are suggested.

This study examined the connotative meaning which beginner ( n = 15), intermediate ( n = 14), and advanced ( n = 15) therapists assigned to time in psychotherapy and their perception of time as a factor in designing therapeutic interventions. Therapists' conceptualization of the subjective experience of time as a component of psychotherapeutic interventions was assessed by examining their selection of metaphors for time, their semantic differential assessments of past, present, and future perspectives, and through their responses to a semistructured interview. Therapists at all three levels of experience appeared to view time for their clients as moving slowly, promoting growth, and allowing progress, with an emphasis on the importance of future time-based interventions for growth while the clients' past was viewed as reflective of distress. Responses appeared to be atheoretical and idiosyncratic, showing lack of clear integration of time with specific treatment interventions.

What are the underlying neurocognitive mechanisms that give rise to mathematical competence? This study investigated the relationship between tests of mathematical ability completed outside the scanner and resting-state functional connectivity (FC) of cytoarchitectonically defined subdivisions of the parietal cortex in adults. These parietal areas are also involved in executive functions (EFs). Therefore, it remains unclear whether there are unique networks for mathematical processing. We investigate the neural networks for mathematical cognition and three measures of EF using resting-state fMRI data collected from 51 healthy adults. Using 10 ROIs in seed to whole-brain voxel-wise analyses, the results showed that arithmetical ability was correlated with FC between the right anterior intraparietal sulcus (hIP1) and the left supramarginal gyrus and between the right posterior intraparietal sulcus (hIP3) and the left middle frontal gyrus and the right premotor cortex. The connection between the posterior portion of the left angular gyrus and the left inferior frontal gyrus was also correlated with mathematical ability. Covariates of EF eliminated connectivity patterns with nodes in inferior frontal gyrus, angular gyrus, and middle frontal gyrus, suggesting neural overlap. Controlling for EF, we found unique connections correlated with mathematical ability between the right hIP1 and the left supramarginal gyrus and between hIP3 bilaterally to premotor cortex bilaterally. This is partly in line with the “mapping hypothesis” of numerical cognition in which the right intraparietal sulcus subserves nonsymbolic number processing and connects to the left parietal cortex, responsible for calculation procedures. We show that FC within this circuitry is a significant predictor of math ability in adulthood.

In environments such as classrooms and offices, complex tasks are performed. A satisfactory acoustic environment is critical for the performance of such tasks. To ensure a good acoustic environment, the right acoustic treatment must be used. The relation between different room acoustic treatments and how they affect speech perception in these types of rooms is not yet fully understood. In this study, speech perception was evaluated for three different configurations using absorbers and diffusers. Twenty-nine participants reported on their subjective experience of speech in respect of different configurations in different positions in a room. They judged sound quality and attributes related to speech perception. In addition, the jury members ranked the different acoustic environments. The subjective experience was related to the different room acoustic treatments and the room acoustic parameters of speech clarity, reverberation time and sound strength. It was found that people, on average, rated treatments with a high degree of absorption as best. This configuration had the highest speech clarity value and lowest values for reverberation time and sound strength. The perceived sound quality could be correlated to speech clarity, while attributes related to speech perception had the strongest association with reverberation time.

The pain clinician is confronted with the formidable task of objectifying the subjective phenomenon of pain so as to determine the right treatments for both the pain syndrome and the patient in whom the pathology is expressed. However, the experience of pain — and its expression — remains enigmatic. Can currently available evaluative tools, questionnaires, and scales actually provide adequately objective information about the experiential dimensions of pain? Can, or will, current and future iterations of biotechnology — whether used singularly or in combination (with other technologies as well as observational-behavioral methods) — afford objective validation of pain? And what of the clinical, ethical, legal and social issues that arise in and from the use — and potential misuse — of these approaches? Subsequent trajectories of clinical care depend upon the findings gained through the use of these techniques and their inappropriate employment – or misinterpretation of the results they provide — can lead to misdiagnoses and incorrect treatment. This essay is the first of a two-part series that explicates how the intellectual tasks of knowing about pain and the assessment of its experience and expression in the pain patient are constituent to the moral responsibility of pain medicine. Herein, we discuss the problem of pain and its expression, and those methods, techniques, and technologies available to bridge the gap between subjective experience and objective evaluation. We address how these assessment approaches are fundamental to apprehend both pain as an objective, neurological event, and its impact upon the subjective experience, existence, and expectations of the person in pain. In this way, we argue that the right use of technology — together with inter-subjectivity, compassion, and insight — can sustain the good of pain care as both a therapeutic and moral enterprise. Key words: pain, assessment, neurotechnology, biotechnology, neuroethics, medicine

We induce a first-person conceptualization of entrepreneurial resilience. Our seven-year, two-study ethnography shows that entrepreneurs enact resilience as a four-step process of managing vulnerability: they richly experience episodes of adversity, self-monitor across episodes, reassess personal thresholds and reconcile challenges with coping skills. Entrepreneurs manage vulnerability by (1) modifying ( stretching and shrinking) objective time and (2) changing their subjective experience of time as working with or against the clock through temporal resourcing or temporal resisting. We extend the theory and practice of entrepreneurial resilience by elaborating the interplay of objective and subjective time in managing vulnerability in recurrent and unprecedented crises.
