The impact of threat of shock-induced anxiety on the neural substrates of memory encoding and retrieval

Dysfunctional memory processes are widely reported in anxiety disorders but the underlying neurocognitive mechanisms are unclear. Recent work shows the impact of anxiety on memory depends on the context and memory modality. For instance, threat of shock, a translational within-subject anxiety induction, has been shown to impair the encoding of facial stimuli, while improving spatial working memory (WM) accuracy. The present study aimed to delineate the neural circuitry regulating these opposing behavioral effects. Thirty-three healthy volunteers performed the previously assessed facial recognition and a spatial WM tasks inside an fMRI scanner, under alternating within-subject conditions of threat or safe from shock across encoding and retrieval. Facial recognition impairments were replicated when threat was selectively induced at encoding. Neuroimaging results suggest that this effect was driven by increased competition for attentional resources within the anterior cingulate cortex, in which activation correlated positively with stress levels. The impact of threat on spatial WM performance did not, however, replicate in the fMRI environment. Nevertheless, state-dependent hippocampal activation was observed in both tasks. These findings suggest a neurocognitive mechanism by which anxiety impairs facial recognition as well as a state-dependent hippocampal activation pattern which may putatively underline retrieval of negative experiences in anxiety

Factors Associated with Research in Management in Australian Commerce and Business Faculties

Measurable research outputs have become part of the overall research management structure within Australian universities in the past ten years. As such, policy makers and administrators alike have come to regard effective management structures and mechanisms as fundamental components of a research environment capable of generating desired quantities of quality outcomes. This paper is based on empirical research carried out over the past year that surveyed academics from commerce and business faculties in Australian universities. The data show that factors such as gender, discipline, and academic level appear to impinge on the relative components that make up research management

FMRI investigation of cross-cultural music comprehension.

The popular view of music as a "universal" language ignores the privileged position of the cultural insider in comprehending musical information unique to their own tradition. The purpose of this study was to test the hypothesis that listeners would demonstrate different neural activity in response to culturally familiar and unfamiliar music and that those differences may be affected by the extent of subjects' formal musical training. Just as familiar languages have been shown to use distinct brain processes, we hypothesized that an analogous difference might be found in music and that it may depend in part on subjects' formal musical knowledge. Using fMRI we compared the activation patterns of professional musicians and untrained controls reared in the United States as they listened to music from their culture (Western) and from an unfamiliar culture (Chinese). No overall differences in activation were observed for either subject group in response to the two musical styles, although there were differences in recall performance based on style and there were activation differences based on training. Trained listeners demonstrated additional activation in the right STG for both musics and in the right and left midfrontal regions for Western music and Chinese music, respectively. Our findings indicate that listening to culturally different musics may activate similar neural resources but with dissimilar results in recall performance

The return to work discussion: A qualitative study of the line manager conversation about return to work and the development of an educational programme

OBJECTIVE: To investigate the conversation between line manager and employee about return to work to inform the development of an online interactive educational programme for line managers to improve the effectiveness of their discussions. DESIGN: An inductive qualitative approach, using the principles of action research and motivational interviewing were adopted. The results informed the development of the educational programme for line managers. SUBJECTS: Middle grade line managers in a large public services employer in the UK. METHODS: Four discussion groups were conducted over a period of 8 months. Line managers explored the challenges of the return to work interview, analysed their interactions with employees and constructed the content of an educational programme. Multiple methods were used to build engagement with participants, including video and role-play. RESULTS: Nine line managers were recruited across 3 business areas. Managers recognised that their conversations focused on the organisations' policies and procedures and the outcome, rather than the interaction. They recognised the strength of shifting style to shared decision-making and guidance rather than process and instruction. These communication strategies were depicted in the educational programme. CONCLUSION: The content and flow of the return to work discussion is of high importance and influences employee behaviour and return to work outcomes

Reviewing ecopsychology research: exploring five databases and considering the future

This brief article aims to provide an overview of the current dispersal of the term ecopsychology within the academic literature. It summarizes the results found when entering the term ecopsychology into five academic databases. The numbers of hits are discussed and comparisons are made with other related terms. The results are further broken down to provide a snapshot of the type of material referred to in these searches. A more detailed inspection of the material referenced in journal articles is undertaken. Here, popular outlets and dates of publication are highlighted. A final search for articles that report original research data directly associated with ecopsychology is also reported. Possible reasons for the low yield and the implications of this are highlighted along with suggested pathways forward

ESR and EISCAT observations of the response of the cusp and cleft to IMF orientation changes

International audienceWe report observations of the cusp/cleft ionosphere made on December 16th 1998 by the EISCAT (European incoherent scatter) VHF radar at Tromsø and the EISCAT Svalbard radar (ESR). We compare them with observations of the dayside auroral luminosity, as seen by meridian scanning photometers at Ny Ålesund and of HF radar backscatter, as observed by the CUTLASS radar. We study the response to an interval of about one hour when the interplanetary magnetic field (IMF), monitored by the WIND and ACE spacecraft, was southward. The cusp/cleft aurora is shown to correspond to a spatially extended region of elevated electron temperatures in the VHF radar data. Initial conditions were characterised by a northward-directed IMF and cusp/cleft aurora poleward of the ESR. A strong southward turning then occurred, causing an equatorward motion of the cusp/cleft aurora. Within the equatorward expanding, southward-IMF cusp/cleft, the ESR observed structured and elevated plasma densities and ion and electron temperatures. Cleft ion fountain upflows were seen in association with elevated ion temperatures and rapid eastward convection, consistent with the magnetic curvature force on newly opened field lines for the observed negative IMF By. Subsequently, the ESR beam remained immediately poleward of the main cusp/cleft and a sequence of poleward-moving auroral transients passed over it. After the last of these, the ESR was in the polar cap and the radar observations were characterised by extremely low ionospheric densities and downward field-aligned flows. The IMF then turned northward again and the auroral oval contracted such that the ESR moved back into the cusp/cleft region. For the poleward-retreating, northward-IMF cusp/cleft, the convection flows were slower, upflows were weaker and the electron density and temperature enhancements were less structured. Following the northward turning, the bands of high electron temperature and cusp/cleft aurora bifurcated, consistent with both subsolar and lobe reconnection taking place simultaneously. The present paper describes the large-scale behaviour of the ionosphere during this interval, as observed by a powerful combination of instruments. Two companion papers, by Lockwood et al. (2000) and Thorolfsson et al. (2000), both in this issue, describe the detailed behaviour of the poleward-moving transients observed during the interval of southward Bz, and explain their morphology in the context of previous theoretical work
