An analysis framework for the integration of broadband NIRS and EEG to assess neurovascular and neurometabolic coupling
Get PDFWith the rapid growth of optical-based neuroimaging to explore human brain functioning, our research group has been developing broadband Near Infrared Spectroscopy (bNIRS) instruments, a technological extension to functional Near Infrared Spectroscopy (fNIRS). bNIRS has the unique capacity of monitoring brain haemodynamics/oxygenation (measuring oxygenated and deoxygenated haemoglobin), and metabolism (measuring the changes in the redox state of cytochrome-c-oxidase). When combined with electroencephalography (EEG), bNIRS provides a unique neuromonitoring platform to explore neurovascular coupling mechanisms. In this paper, we present a novel pipeline for the integrated analysis of bNIRS and EEG signals, and demonstrate its use on multi-channel bNIRS data recorded with concurrent EEG on healthy adults during a visual stimulation task. We introduce the use of the Finite Impulse Response functions within the General Linear Model for bNIRS and show its feasibility to statistically localize the haemodynamic and metabolic activity in the occipital cortex. Moreover, our results suggest that the fusion of haemodynamic and metabolic measures unveils additional information on brain functioning over haemodynamic imaging alone. The cross-correlation-based analysis of interrelationships between electrical (EEG) and haemodynamic/metabolic (bNIRS) activity revealed that the bNIRS metabolic signal offers a unique marker of brain activity, being more closely coupled to the neuronal EEG response
Retrospection, regret, and contingency in Dickens’s late midlives
Get PDFThis essay explores Dickens’s representations of male anxieties over aging and argues both that contingency—a character’s dawning recognition that their life might have been otherwise—haunts Dickens’s midlife narratives and that a developing cultural awareness of midlife as a life-stage is central to the Victorian fascination with unlived lives. It traces developments in Dickens’s own sense of midlife’s particularity to two sources: a recognition of the bodily changes that accompany the process of aging (such as his own graying hair, which he sought to disguise cosmetically through hair and moustache dyes) and his membership of a generation whose life chances were determined by a demographic bulge caused by a rapid expansion of Britain’s middle-aged and elderly population. Both of these circumstances engender an overwhelming sense of regret in the aging protagonists of novels such as David Copperfield (1849-1850), Great Expectations (1860-1861), and Our Mutual Friend (1864-1865), whose midlives are spent thinking, and sometimes writing, about the youthful choices that shaped their later lives. It is only with the publication of the late portmanteau tale “Mugby Junction” that Dickens finds himself able to imagine a midlife in which the aging individuals possess agency and are empowered to cast off the determining and contingent events of their Bildungsroman narratives and engage in the processes of unbecoming and self-renewal
Tactile Distance Anisotropy on the feet
Get PDFPerception of distance between two touches varies with orientation on the hand, with distances aligned with hand width perceived as larger than those aligned with hand length. Similar anisotropies are found on other body parts (e.g., the face), suggesting they may reflect a general feature of tactile organization, but appear absent on other body parts (e.g., the belly). Here, we investigated tactile distance anisotropy on the foot, a body part structurally and embryologically similar to the hand, but with very different patterns of functional usage in humans. In three experiments, we compared the perceived distance between pairs of touches aligned with the medio-lateral and proximal-distal foot axes. On the hairy skin of the foot dorsum, anisotropy was consistently found, with distances aligned with the medio-lateral foot axis perceived as larger than those in the proximo-distal axis. In contrast, on the glabrous skin of the sole, inconsistent results were found across experiments, with no overall evidence for anisotropy. This shows a pattern of anisotropy on the foot broadly similar to the hand, adding to the list of body parts showing tactile distance anisotropy, and providing further evidence that such biases are a general aspect of tactile spatial organization across the body
REMBI: Recommended Metadata for Biological Images—enabling reuse of microscopy data in biology
No full textBioimaging data have significant potential for reuse, but unlocking this potential requires systematic archiving of data and metadata in public databases. We propose draft metadata guidelines to begin addressing the needs of diverse communities within light and electron microscopy. We hope this publication and the proposed Recommended Metadata for Biological Images (REMBI) will stimulate discussions about their implementation and future extension

Depression and anxiety symptoms associated with internet gaming disorder before and during the COVID-19 pandemic: a longitudinal study
Get PDFBackground: The coronavirus disease-2019 (COVID-19) pandemic has profoundly impacted aspects of human life globally. Playing videogames has been encouraged by several organizations to help individuals cope with the COVID-19 pandemic and associated restrictive measures. This longitudinal study was the first to examine gaming in the context of the pandemic and its association with depressive and anxiety symptoms.
Methods: The sample comprised 1,778 children and adolescents (50.7% male) who were part of the Project of School Mental Health in Southwest China. Data were collected at two-time intervals: before the COVID-19 pandemic (October to November 2019 – [T1]) and during the COVID-19 pandemic (April to May 2020 – [T2]). Data were collected on perceived COVID-19 impacts, videogame use, Internet Gaming Disorder (IGD), and depressive and anxiety symptoms. Cross-lagged panel models were computed to examine longitudinal relationships.
Results: The results indicated that both videogame use and IGD increased significantly for adolescents at T2. The cross-lagged panel model results suggested that depressive and anxiety symptoms at T1 positively predicted IGD and videogame use at T2 (especially for boys), but not inversely. Perceived COVID-19 impacts mediated the relationship between depressive and anxiety symptoms at T1 and IGD at T2.
Conclusion: Children and adolescents both increased videogame use at T2, but only adolescents significantly increased IGD severity at T2. The findings supported the compensatory hypothesis, and are consistent with the Interaction of Person-Affect-Cognition-Execution model as individual responses to COVID-19 may function as a mediator between personal predisposing variables and IGD

When doing good will not save us: revisiting the buffering effect of CSR following service failures
Get PDFPast research offers inconsistent evidence on whether CSR is an effective service recovery strategy. Current debates overlook the signals that service failures send about the company, and their interplay with CSR. We propose a moderated mediation model showing that CSR's effectiveness for service recovery depends upon failure type. For failures signaling a lack of skills and expertise, CSR enhances warmth which in turn lowers revenge. Warmth further increases perceived competence which influences conciliatory responses. CSR, however, does not help if the failure signals a lack of moral integrity. Both warmth and competence explain the CSR's buffering effect. Our study demonstrates that “doing good” helps only to the extent that service failures that do not raise doubts about the character of the company. Even in these circumstances, however, the buffering effect of CSR is observed only in case of customer–firm communal relationships. Consistent evidence from three experiments revisits more optimistic assessments of the ability of CSR to act as a recovery strategy and shows that CSR can help only under very circumscribed conditions. Managerially, we show how and when the CSR buffer applies in service contexts, offering insights on how managers can best reap the potential benefits of service brands' involvement in CSR
