Modulation of putative mirror neuron activity by both positively and negatively valenced affective stimuli: a TMS study

Research indicates that mirror neurons are important for social cognition, including emotion processing. Emerging evidence, however, also reveals that emotional stimuli might be capable of modulating human mirror neuron system (MNS) activity.

The current study used transcranial magnetic stimulation (TMS) to assess putative mirror neuron function following emotionally evocative images in twenty healthy adults.

Participants observed videos of either a transitive hand action or a static hand while undergoing TMS of the primary motor cortex. In order to examine the effect of emotion on the MNS, each video was preceded by an image of either a positive, negative or neutral valence.

MNS activity was found to be augmented by both the positive and negative (relative to neutral) stimuli, thus providing empirical support for a bi-directional link between emotion and the MNS, whereby both positively and negatively valenced stimuli are capable of facilitating mirror neuron activity. The potential adaptive significance of this finding is discussed. 

Short- and long-term consequences of early developmental conditions : a case study on wild and domesticated zebra finches

Divergent selection pressures among populations can result not only in significant differentiation in morphology, physiology and behaviour, but also in how these traits are related to each other, thereby driving the processes of local adaptation and speciation. In the Australian zebra finch, we investigated whether domesticated stock, bred in captivity over tens of generations, differ in their response to a life-history manipulation, compared to birds taken directly from the wild. In a ‘common aviary’ experiment, we thereto experimentally manipulated the environmental conditions experienced by nestlings early in life by means of a brood size manipulation, and subsequently assessed its short- and long-term consequences on growth, ornamentation, immune function and reproduction. As expected, we found that early environmental conditions had a marked effect on both short- and long-term morphological and life-history traits in all birds. However, although there were pronounced differences between wild and domesticated birds with respect to the absolute expression of many of these traits, which are indicative of the different selection pressures wild and domesticated birds were exposed to in the recent past, manipulated rearing conditions affected morphology and ornamentation of wild and domesticated finches in a very similar way. This suggests that despite significant differentiation between wild and domesticated birds, selection has not altered the relationships among traits. Thus, life-history strategies and investment trade-offs may be relatively stable and not easily altered by selection. This is a reassuring finding in the light of the widespread use of domesticated birds in studies of life-history evolution and sexual selection, and suggests that adaptive explanations may be legitimate when referring to captive bird studies.

My road ahead study protocol: a randomised controlled trial of an online psychological intervention for men following treatment for localised prostate cancer

There is a need for psychosocial interventions for men with prostate cancer to promote adaptive coping with the challenges and distress associated with diagnosis, treatment and recovery. In addition, interventions are needed that help to overcome barriers to psychosocial treatment such as limited face-to-face psychosocial support services, a shortage of adequately trained professionals, geographical distance, perceived and personal stigma and a preference for consumer-centric and self-directed learning. My Road Ahead is an online cognitive behaviour therapy (CBT) intervention for prostate cancer. This protocol describes a randomised controlled trial (RCT) that will evaluate the efficacy of this online intervention alone, the intervention in combination with a moderated online forum, and the moderated online forum alone.

Adaptive translational cueing motion algorithm using fuzzy based tilt coordination

Driving simulators have become useful research tools for the institution and laboratories which are studying in different fields of vehicular and transport design to increase road safety. Although classical washout filters are broadly used because of their short processing time, simplicity and ease of adjust, they have some disadvantages such as generation of wrong sensation of motions, false cue motions, and also their tuning process which is focused on the worst case situations leading to a poor usage of the workspace. The aim of this study is to propose a new motion cueing algorithm that can accurately transform vehicle specific force into simulator platform motions at high fidelity within the simulator’s physical limitations. This method is proposed to compensate wrong cueing motion caused by saturation of tilt coordination rate limit using an adaptive correcting signal based on added fuzzy logic into translational channel to minimize the human sensation error and exploit the platform more efficiently.

Economic resilience of regions under crises: a study of the Australian economy

Courvisanos J., Jain A. and Mardaneh K. Economic resilience of regions under crises: a study of the Australian economy, Regional Studies. Identifying patterns of economic resilience in regions by industry categories is the focus of this paper. Patterns emerge from adaptive capacity in four distinct functional groups of local government regions in Australia, in respect of their resilience from shocks on specific industries. A model of regional adaptive cycles around four sequential phases – reorganization, exploitation, conservation and release – is adopted as the framework for recognizing such patterns. A data-mining method utilizes a k-means algorithm to evaluate the impact of two major shocks – a 13-year drought and the Global Financial Crisis – on four functional groups of regions, using census data from 2001, 2006 and 2011.

Adaptive fuzzy multi-surface sliding control of multiple-input and multiple-output autonomous flight systems

In this study, we proposed an adaptive fuzzy multi-surface sliding control (AFMSSC) for trajectory tracking of 6 degrees of freedom inertia coupled aerial vehicles with multiple inputs and multiple outputs (MIMO). It is shown that an adaptive fuzzy logic-based function approximator can be used to estimate the system uncertainties and an iterative multi-surface sliding control design can be carried out to control flight. Using AFMSSC on MIMO autonomous flight systems creates confluent control that can account for both matched and mismatched uncertainties, system disturbances and excitation in internal dynamics. It is proved that the AFMSSC system guarantees asymptotic output tracking and ultimate uniform boundedness of the tracking error. Simulation results are presented to validate the analysis.

Tradition : connecting the past and present : a case study of Xintiandi in Shanghai

Tradition and modernisation are often seen as a binary opposition. In an urban environment, traditional built form seems incompatible to modern way of life, and the adaptation of traditional neighbourhoods to modern use often causes controversy. Nowadays, ideas about ‘what is tradition’ become shifting, and traditional townscape does not necessarily mean an obstacle to modernisation. This paper reveals how the role of traditional elements is played in China’s urban development. The case study of Xintiandi, Shanghai, where traditional townscape is restored, highlights the connection of the city’s past and present. Xintiandi is a successful yet controversial city renewal project, where Shanghai’s traditional housing form Shikumen is restored and put into adaptive uses. In the course of urban modernisation, the role of tradition as a representation of the connection between the city’s past and present deserves more study. This paper aims to add a perspective to the literature on the study of tradition. It argues for the diversity and fluidity of the ideas about tradition., In this view, tradition is not necessarily in dichotomy with, or opposite to modernisation; rather, tradition justifies the needs of modernisation and supplements its outcomes. The paper is developed in light of works on tradition by Shils, Hobsbawm, Giddens and others; The case study of Xintiandi shows what Old Shanghai tradition means to this city today, and how traditional elements are adapted and used in the course of urban modernisation.

Patient safety issues and concerns in Bhutan’s healthcare system: a qualitative study.

This study identified medication errors, healthcare associated infections, diagnostic errors, surgical errors, laboratory errors and a lack of infrastructure to progress patient safety in hospital contexts as major concerns in the resource poor nation of Bhutan. A culturally adaptive Bhutanised approach to redress these concerns and improve patient safety is proposed.
