Growing evidence suggests that natural environments – whether in outdoor or indoor settings – foster psychological health and physiological relaxation, indicated by increased wellbeing, reduced stress levels, and increased parasympathetic activity. Greater insight into differential psychological aspects modulating psychophysiological responses to nature-based relaxation videos could help understand modes of action and develop personalized relaxation interventions. We investigated heart rate variability as an indicator of autonomic regulation, specifically parasympathetic activity, in response to a 10-min video intervention in two consecutive studies as (...) well as heart rate. We hypothesized that a nature-based relaxation video elicits HRV increase and HR decrease, with response magnitude being affected by aspects of early life adversity and trait mindfulness. In Study 1, N = 60 participants watched a relaxation video intervention depicting different natural scenery. We analyzed changes in HR and respiratory sinus arrhythmia as a standard HRV measure, both based on 3-min segments from the experimental session, in multiple growth curve models. We found a decrease in HR and increase of RSA during the video intervention. Higher paternal care and lower trait mindfulness observing skills were associated with higher RSA values before but not during video exposure. In Study 2, N = 90 participants were assigned to three video conditions: natural scenery from Study 1, meditation video, or short clip from “The Lord of the Rings.” Again, HR decreased, and RSA increased during video segments, yet without expected group differences across different video types. We found higher parental care and lower parental overprotection to predict higher RSA at different times during the experiment. Interestingly, lower paternal overprotection predicted overall higher RSA. These results suggest a generic relaxation effect of video interventions on autonomic regulation that we discuss in light of different theories mapping restorative effects of natural environments. Further, psychological characteristics like aspects of early life adversity and trait mindfulness could contribute to individual differences in autonomic regulation. This study contributes to a better understanding of autonomic and psychological responses to relaxation videos. (shrink)

Working memory is the system responsible for maintaining and manipulating information, in the face of ongoing distraction. In turn, WM span is perceived to be an individual-differences construct reflecting the limited capacity of this system. Recently, however, there has been some evidence to suggest that WM capacity can increase through training, raising the possibility that training can functionally alter the neural structures supporting WM. To address the hypothesis that the neural substrates underlying WM are targeted by training, we conducted a (...) meta-analysis of functional magnetic resonance imaging studies of WM training using Activation Likelihood Estimation. Our results demonstrate that WM training is associated exclusively with decreases in blood oxygenation level-dependent responses in clusters within the fronto-parietal system that underlie WM, including the bilateral inferior parietal lobule, middle and superior frontal gyri, and medial frontal gyrus bordering on the cingulate gyrus. We discuss the various psychological and physiological mechanisms that could be responsible for the observed reductions in the BOLD signal in relation to WM training, and consider their implications for the construct of WM span as a limited resource.

We conceptualise CSR communication as a process of reciprocal influence between organisations and their audiences. We use an illustrative case study in the form of a conflict between firms and a powerful stakeholder which is played out in a series of 20 press releases over a 2-month period to develop a framework of analysis based on insights from linguistics. It focuses on three aspects of dialogism, namely (i) turn-taking (co-operating in a conversation by responding to the other party), (ii) inter-party (...) moves (the nature and type of interaction characterising a turn, i.e. denial, apology or excuse) and (iii) intertextuality (the intensity and quality of verbal interaction between the parties). We address the question: What is the nature and type of verbal interactions between the parties? First we examine (a) whether the parties verbally interact and then (b) whether the parties listen to each other. We find evidence of dialogism suggesting that CSR communication is an interactive process which has to be understood as a function of the power relations between a firm and a specific stakeholder. Also, we find evidence of intertextuality in press releases by six firms which engage in verbal interaction with the stakeholder. We interpret this as linguistic evidence of isomorphic processes relating to CSR practices resulting from the pressure exerted by a powerful stakeholder. The lack of response by ten firms that fail to issue press releases suggests a strategy of ‘watch-and-wait’ with respect to the outcome of the conflict. (shrink)

Intolerance and hostility toward Marxism on the part of bourgeois philosophy have been a constant over the entire 125-year history of Marxism. The expressions of this hostility and the forms and methods of struggle have been variables that have changed substantially as Marxism has developed and as the relationship among the conflicting forces has undergone modification.

Apparently objective and value-free `scientific' assessments of health risks are often highly value-laden and incorporate contentious social assumptions. Mr Wynne exposes some of the complexities underlying attempts to compare the health risks of nuclear and other sources of energy.
