Reactive oxygen species (ROS) are known as toxic metabolic products in plants and other aerobic organisms. An elaborate and highly redundant plant ROS network, composed of antioxidant enzymes, antioxidants and ROS-producing enzymes, is responsible for maintaining ROS levels under tight control. This allows ROS to serve as signaling molecules that coordinate an astonishing range of diverse plant processes. The specificity of the biological response to ROS depends on the chemical identity of ROS, intensity of the signal, sites of production, plant (...) developmental stage, previous stresses encountered and interactions with other signaling molecules such as nitric oxide, lipid messengers and plant hormones. Although many components of the ROS signaling network have recently been identified, the challenge remains to understand how ROS-derived signals are integrated to eventually regulate such biological processes as plant growth, development, stress adaptation and programmed cell death.

An increasing number of financial services (FS) companies are adopting solutions driven by artificial intelligence (AI) to gain operational efficiencies, derive strategic insights, and improve customer engagement. However, the rate of adoption has been low, in part due to the apprehension around its complexity and self-learning capability, which makes auditability a challenge in a highly regulated industry. There is limited literature on how FS companies can implement the governance and controls specific to AI-driven solutions. AI auditing cannot be performed in (...) a vacuum; the risks are not confined to the algorithm itself, but rather permeates the entire organization. Using the risk of unfairness as an example, this paper will introduce the overarching governance strategy and control framework to address the practical challenges in mitigating risks AI introduces. With regulatory implications and industry use cases, this framework will enable leaders to innovate with confidence. (shrink)

This article aims to develop new conceptions of the psychosocial dynamics that drive the re-romanticization of domestic femininity in current financialized capitalism. Feminist scholars have described this heightened cultivation of mothering as a reparative move in response to irreconcilable tensions between cultural ideals of the ‘balancing mother’ and ‘lean-in femininity’. This article adds a materialist-psychosocial lens to these conceptions, to enhance understanding of what drives this craving for domestic femininity. Drawing on a free-association narrative interview study with couples in the (...) financial elite in the comparatively gender-egalitarian Norwegian context, I describe a specific emotional mechanism that resists democratization of gender in this specific group. The interviews reveal a felt need to cultivate ‘the human side of things’ at safe distance from the competitiveness of ‘hard-core finance’. The Nordic earner–carer model with its entwinement of care and professional pursuits, cultivated by the more self-fulfilment-oriented parts of the professional middle-class appears not only unwanted but threatening. In my analysis, I retrieve and develop a psychoanalytically inspired historical-materialist feminism, one that perceives of the gendered division of work as a split in modes of focusing human energy. I suggest that the resurgent cultivation of domestic femininity is nurtured by a self-energizing antagonism between competitive and relational practices. I further argue that the cultivation of domestic femininity in these financial couples points to a potential antagonism between the democratization of love and the specific anxiety-driven competitiveness to which this financial-elite group may be particularly susceptible.

On March 12, 2018, I received an email from André De Tienne, General Editor of the Peirce Edition Project. He recommended that I visit the Francis Blake archives at the Massachusetts Historical Society, remarking, Francis Blake was a cousin of Charles Peirce. I have not yet figured out how that cousinage works out genealogically. In any case, on 13 January 1893, the day CSP and Juliette returned from Boston to New York after the Lowell Lectures, they first took a trip (...) to Weston, MA, to visit Frank Blake, and from there they went to Worcester to visit W. Stanley Hall at Clark University. … If you look in folder R L49, it... (shrink)

This article examines the relationship between discourses of motherhood and discourses of employment for contemporary middle-class women. Drawing on data from a study of the transition to motherhood conducted in Bristol, UK, it is suggested that there are important continuities as well as con icts between the discursive construction of these two spheres. In consequence, a variety of relationships may be established between mothering and employment identities. The concept of `inter-spatiality' is suggested to conceptualize how the women negotiated the relationship (...) between the two. The findings suggest both that women do not necessarily experience con ict between these two sources of identity, and that they may have a degree of agency in negotiating the relationship between these interlocking parts of their lives.

This article aims to contribute to the currently sparse literature on transnational families and gender. It focuses on the retrospective accounts of Caribbean-born adults who as children were serial migrants, joining their parents in the UK following a period of separation. It considers aspects of their relationships with their siblings and with their mothers and fathers. The article illuminates what the serial migrants viewed as contradictory everyday practices that produced ‘non-shared environments’. It discusses three ways in which transnationalism appeared to (...) be a central part of the serial migrants’ family lives. First, it was embodied. Second, it was lived as cultural difference between Caribbean-born and UK-born siblings. Third, it was reported to be evident in parental practices. The article illustrates the importance of viewing gendered narratives in a psychosocial intersectional perspective. (shrink)
