Older and wiser? Menâs and womenâs accounts of drinking in early mid-life
Most qualitative research on alcohol focuses on younger rather than older adults. To explore older peopleâs relationship with alcohol, we conducted eight focus groups with 36 men and women aged 35 to 50 years in Scotland, UK. Initially, respondents suggested that older drinkers consume less alcohol, no longer drink to become drunk and are sociable drinkers more interested in the taste than the effects of alcohol. However, as discussions progressed, respondents collectively recounted recent drunken escapades, challenged accounts of moderate drinking, and suggested there was still peer pressure to drink. Some described how their drinking had increased in mid-life but worked hard discursively to emphasise that it was age and stage appropriate (i.e. they still met their responsibilities as workers and parents). Women presented themselves as staying in control of their drinking while men described going out with the intention of getting drunk (although still claiming to meet their responsibilities). While women experienced peer pressure to drink, they seemed to have more options for socialising without alcohol than did men. Choosing not to drink alcohol is a behaviour that still requires explanation in early mid-life. Harm reduction strategies should pay more attention to drinking in this age group
Reconsidering memorisation in the context of non-tonal piano music
Performers, pedagogues and researchers have shared interest in the topic of musical memorisation for centuries. A large and diverse body of studies on this subject has contributed to the current understanding of musiciansâ views of performing from memory, as well as the mechanisms governing encoding and retrieval of musical information. Nevertheless, with a few exceptions, existing research is still highly based on tonal music and lacks further examination in the musical world of non-tonality. The convention of performing from memory is a well-established practice for particular instruments and musical genres, but an exception is often made for recent styles of repertoire moving away from tonality. No study to date has systematically investigated the reasons for such exception and musiciansâ views on this matter. Moreover, the existing principles of memorisation that are thought to apply to musicians in the highest levels of skill are strongly based on the use of conceptual knowledge of tonal musical vernacular. Such knowledge is often obscured or absent in non-tonal repertoire.
This thesis aims to extend the findings of previous research into musical memorisation in the context of non-tonal piano repertoire by documenting pianistsâ views and practices in committing this music to memory. An interview study with pianists expert in contemporary music (Chapter 3) establishes the background for the thesis. A variety of views on performing contemporary music from memory were reported, with several pianists advocating benefits from performing this repertoire by heart and others from using the score. Memorisation accounts revealed idiosyncrasy and variety, but emphasised the importance of specific strategies, such as the use of mental rehearsal, principles of chunking applicable to this repertoire and the importance of different types of memory and their combination.
The second study (Chapter 4) explores the topic in further depth, by thoroughly examining the authorâs entire process of learning and memorising a newly commissioned non-tonal piece for prepared piano. This study extends findings from performance cue (PC) theory. This widely recognised account of expert memory in music suggests that musicians develop retrieval schemes hierarchically organised around their understanding of musical structure, using different types of PCs. The use of retrieval schemes in this context is confirmed by this study. The author organised the scheme around her own understanding of musical structure, which was gradually developed while working through the piece, since the music had no aural model available or ready-made structural framework to hold on to early in the process. Extending previous research, new types of PCs were documented and, for the first time, negative serial position effects were found for basic PCs (e.g., fingering, notes, patterns) in long-term recall. Finally, the study provided behavioural evidence for the use of chunking in non-tonal piano music.
The third study (Chapters 5 and 6) extends these findings to a serial piece memorised by six pianists. Following a multiple-case study approach, this study observed in great depth memorisation approaches carried out by two of those pianists, who performed the music very accurately from memory, and by one pianist who performed less accurately. The first two pianists developed retrieval schemes based on their understanding of musical structure and different types of PCs, mainly basic and structural. Comparisons between the pianists revealed very different views of musical structure in the piece. Even so, both musicians used such understanding to organise encoding and retrieval. The pianist with the least accurate performance adopted an unsystematic approach, mainly relying on incidental memorisation. The absence of a conceptual retrieval scheme resulted in an inability to fully recover from a major memory lapse in performance.
The findings of this research provide novel insights into pianistsâ views towards performing non-tonal music from memory and into the cognitive mechanisms governing the encoding and retrieval of this music, which have practical applications for musicians wishing to memorise non-tonal piano music
Neutralizer and sample chamber for the Atomic Oxygen Simulation System (AOSS)
A neutralizer system capable of converting a beam of oxygen ions (O(+) or O2(+)) into a beam of low-energy neutral oxygen atoms (O) was developed. The neutralizer system is to be designed to be compatible with the Atomic Oxygen Simulation System (AOSS) located in the Physical Science Branch of MSFC. The Center for Molecular and Atomic Studies at Surfaces (CMASS) at Vanderbilt University has met these objectives by developing a system that neutralizes the ions through electron transfer during a grazing-incidence reflection of an ion beam from a smooth nickel surface. The purpose is to describe the system, provide schematic representations of the system, and to discuss the use of the system in relation to the AOSS at the Physical Science Branch of MSFC
Human immunodeficiency virus rebound after suppression to < 400 copies/mL during initial highly active antiretroviral therapy regimens, according to prior nucleoside experience and duration of suppression
This study evaluated 1433 human immunodeficiency virus (HIV)-infected patients starting highly active antiretroviral therapy (HAART), 409 (28%) of whom had prior nucleoside experience and achieved an HIV load of <400 copies/mL by 24 weeks of therapy. Three hundred seven patients experienced virus rebound during a total of 2773.3 person-years of follow-up. There was a higher rate of virus rebound among the patients with pre-HAART nucleoside experience (relative hazard [RH], 2.86; 95% confidence interval, 2.22-3.84; P < .0001) and a decreasing rate of virus rebound with increasing duration of virus suppression (i.e., time since achieving a virus load of <400 HIV RNA copies/mL) among both the nucleoside-experienced and naive patients (P < .0001), but the difference between the groups persisted into the third year of follow-up (P = .0007). Even patients who had experienced <2 months of nucleoside therapy before beginning HAART had an increased risk of virus rebound (RH, 1.95; P = .009). It appears that only a small period of pre-HAART nucleoside therapy is sufficient to confer a disadvantage, in terms of risk of virus rebound, that persists for several years
Understanding and informing decisions on Sustainable Agricultural Intensification in Sub-Saharan Africa
Sustainable Agricultural Intensification (SAI) was initially defined as increasing agricultural production without adverse environmental impacts and without increasing the area under agriculture. Overtime the concept has been broadened to integrate social, economic, and environmental components of sustainability, each of which covers multiple facets or indicators of performance. It is recognized however that it may not be possible to optimise all these aspects of sustainability simultaneously and that trade-offs between them are likely to occur, although synergies are also possible. There has been disagreement over how to achieve SAI, with some proposing that only an âagroecologicalâ intensification pathway delivers sustainability. Others take a broader perspective arguing that all aspects of ecological, genetic, and socio-economic intensification need to be considered, but then assessed in terms of the sustainability of the outcomes. A major concern is that intensification that focuses on agricultural technology can lead to inequitable outcomes for women and poorer households, while agroecological intensification building upon local capitals is generally considered more equitable. Understanding the potential outcomes and inherent trade-offs of different approaches requires interdisciplinary research, evidence and decision-making tools, some examples of which are presented in this Special Issue
An exploration of the collaborative processes of making theatre inspired by science
This research examined the collaborative processes of making theatre inspired by science through the analysis of 16 semi-structured interviews with individual collaborators (eight theatre practitioners and eight scientists). Interviews explored experiences, including their motivations, working processes, challenges, learning and understanding. Roles of scientists in the collaboration ranged from expert advisor to equal creative collaborator. Factors affecting partnerships included curiosity for each other's practice, social interaction and mutual respect. The research suggests that scientists could be motivated to undertake 'Sci-Art' collaborations through personal interest, as well as previously identified motives such as encouragement from their department. The project also identified benefits to researchers from such collaborations, including developing new perspectives on their own practice. Š The Author(s) 2011

Kurt Symanzik - a stable fixed point beyond triviality
In 1970 Kurt Symanzik proposed a "precarious" phi**4-theory with a negative
quartic coupling constant as a valid candidate for an asymptotically free
theory of strong interactions. Symanzik's deep insight in the non-trivial
properties of this theory has been overruled since then by the Hermitian
intuition of generations of scientists, who considered or consider this
actually non-Hermitian highly important theory to be unstable. This short -
certainly controversial - communication tries to shed some light on the
historical and formalistic context of Symanzik's theory in order to sharpen our
(quantum) intuition about non-perturbative theoretical physics between
(non)triviality and asymptotic freedom.Comment: 6 pages, no figures, new style files, revised for typos, improved

Online support system for students in higher education: Proof-of-concept study
Background: Providing support to the increasing numbers of students facing mental health difficulties in higher education (HE) can be difficult due to stigma or lack of resources. Alternative and/or complementary sources of support are needed, such as online interventions that are recognised for their therapeutic value and cost-effectiveness.
Objectives: We aim to provide evidence supporting the conceptual and practical value of a newly developed online multimedia intervention system for HE students who face mild to moderate symptoms of anxiety and depression and study-skills difficulties.
Methods: Students from five universities were invited to participate in a cross-sectional proof-of-concept study. Students were invited through the universities' internal communication channels. Following demonstration of each part of the system, students completed a survey with quantitative and qualitative questions.
Results: Response was largely positive. Positive responses on the features of the questionnaire ranged between 65% and 86%; on the features of the workshops ranged between 57% and 91%; on 'My place' ranged between 65% and 79%; on the animated videos ranged between 79% and 92%; and on the overall system ranged between 78% and 89%. Participants indicated areas for improvement and ways in which such improvement could be accomplished; these then guided the development of the system.
Conclusions: The results confirm the need for such a system. It can complement student support services (SSS) by dealing with cases with mild to moderate difficulties, hence allowing SSS to prioritise and effectively address more severe cases. Potentially this method can provide a meaningful alternative to SSS; this is worth investigating further
