Is mindfulness Buddhist? (and why it matters).

Modern exponents of mindfulness meditation promote the therapeutic effects of "bare attention"--a sort of non-judgmental, non-discursive attending to the moment-to-moment flow of consciousness. This approach to Buddhist meditation can be traced to Burmese Buddhist reform movements of the first half of the 20th century, and is arguably at odds with more traditional Theravāda Buddhist doctrine and meditative practices. But the cultivation of present-centered awareness is not without precedent in Buddhist history; similar innovations arose in medieval Chinese Zen (Chan) and Tibetan Dzogchen. These movements have several things in common. In each case the reforms were, in part, attempts to render Buddhist practice and insight accessible to laypersons unfamiliar with Buddhist philosophy and/or unwilling to adopt a renunciatory lifestyle. In addition, these movements all promised astonishingly quick results. And finally, the innovations in practice were met with suspicion and criticism from traditional Buddhist quarters. Those interested in the therapeutic effects of mindfulness and bare attention are often not aware of the existence, much less the content, of the controversies surrounding these practices in Asian Buddhist history

‘Paying Attention’ in a Digital Economy: Reflections on the Role of Analysis and Judgement Within Contemporary Discourses of Mindfulness and Comparisons with Classical Buddhist Accounts of Sati

This chapter examines the question of the role of intellectual analysis and ethical judgement in ancient Indian Buddhist accounts of sati and contemporary discourses about ‘mindfulness’. Attention is paid to the role of paññ? (Sanskrit: prajñ?: ‘wisdom’ or ‘analytical insight’) and ethical reflection in the cultivation of sati in mainstream Abhidharma and early Mah?y?na philosophical discussions in India, noting the existence of a subordinate strand of Buddhist thought which focuses upon the non-conceptuality of final awakening (bodhi) and the quiescence of mind. Modern discourses of mindfulness are examined in relation to detraditionalization, the global spread of capitalism and widespread adoption of new information technologies. It is argued that analysis of the exponential growth in popularity of ‘mindfulness’ techniques must be linked to an exploration of the modern history of attention, more specifically, the possibility that the use of fast-paced, digital, multimedia technologies is facilitating a demand for fragmented or dispersed attention. It is argued that the fault line between divergent contemporary accounts of mindfulness can be seen most clearly over the issue of the role of ethical judgements and mental ratiocination within mindfulness practice. The two most extreme versions on this spectrum see mindfulness on the one hand as a secular mental technology for calming the mind and reducing stress and discomfort, and on the other as a deeply ethical and experiential realization of the geopolitics of human experience. These, it is suggested, constitute an emerging discursive split in accounts of mindfulness reflective of divergent responses to the social, economic, political and technological changes occurring in relation to the global spread of neoliberal forms of capitalism

Using candidacy theory to explore unemployed over-50s perceptions of suitability of a welfare to work programme: a longitudinal qualitative study

Welfare to work interventions seek to move out‐of‐work individuals from claiming unemployment benefits towards paid work. However, previous research has highlighted that for over‐50s, particularly those with chronic health conditions, participation in such activities are less likely to result in a return to work. Using longitudinal semi‐structured interviews, we followed 26 over‐50s during their experience of a mandated welfare to work intervention (the Work Programme) in the United Kingdom. Focusing on their perception of suitability, we utilise and adapt Candidacy Theory to explore how previous experiences of work, health, and interaction with staff (both in the intervention, and with healthcare practitioners) influence these perceptions. Despite many participants acknowledging the benefit of work, many described a pessimism regarding their own ability to return to work in the future, and therefore their lack of suitability for this intervention. This was particularly felt by those with chronic health conditions, who reflected on difficulties with managing their conditions (e.g., attending appointments, adhering to treatment regimens). By adapting Candidacy Theory, we highlighted the ways that mandatory intervention was navigated by all the participants, and how some discussed attempts to remove themselves from this intervention. We also discuss the role played by decision makers such as employment‐support staff and healthcare practitioners in supporting or contesting these feelings. Findings suggest that greater effort is required by policy makers to understand the lived experience of chronic illness in terms of ability to RTW, and the importance of inter‐agency work in shaping perceptions of those involved

Orexinergic Input to Dopaminergic Neurons of the Human Ventral Tegmental Area

The mesolimbic reward pathway arising from dopaminergic (DA) neurons of the ventral tegmental area (VTA) has been strongly implicated in reward processing and drug abuse. In rodents, behaviors associated with this projection are profoundly influenced by an orexinergic input from the lateral hypothalamus to the VTA. Because the existence and significance of an analogous orexigenic regulatory mechanism acting in the human VTA have been elusive, here we addressed the possibility that orexinergic neurons provide direct input to DA neurons of the human VTA. Dual-label immunohistochemistry was used and orexinergic projections to the VTA and to DA neurons of the neighboring substantia nigra (SN) were analyzed comparatively in adult male humans and rats. Orexin B-immunoreactive (IR) axons apposed to tyrosine hydroxylase (TH)-IR DA and to non-DA neurons were scarce in the VTA and SN of both species. In the VTA, 15.062.8% of TH-IR perikarya in humans and 3.260.3% in rats received orexin B-IR afferent contacts. On average, 0.2460.05 and 0.0560.005 orexinergic appositions per TH-IR perikaryon were detected in humans and rats, respectively. The majority(86–88%) of randomly encountered orexinergic contacts targeted the dendritic compartment of DA neurons. Finally, DA neurons of the SN also received orexinergic innervation in both species. Based on the observation of five times heavierorexinergic input to TH-IR neurons of the human, compared with the rat, VTA, we propose that orexinergic mechanism acting in the VTA may play just as important roles in reward processing and drug abuse in humans, as already established well in rodents

From Youth Team to First Team: An Investigation into the Transition Experiences of Young Professional Athletes in Football

Using Wylleman and Lavallee (2004) and Stambulova (2003) models of transition as conceptual frameworks for the current study, we aimed to explore United Kingdom (UK) professional soccer players’ (N = 5) experiences going through a youth-to-senior career transition to first team level, and assess the immediate changes that occur during the move. Few studies have assessed this process, and no studies have focused on assessing the changes that may occur between pre and post transition. Data collection lasted 1 month with players interviewed twice, 2 weeks before, and 2 weeks after their transition to the first team. Data were abductively thematically content analyzed. Prior to transition, players reported high motivation to be successful, but also feeling anxious about the transition to senior sport. Post-transition, players felt more confident about their ability to succeed in senior sport and maintained high levels of motivation to succeed. Family, friends, coaches, and teammates provided emotional, technical, and tangible support to the players throughout the transition, but were also sources of stress for athletes moving to senior sport. These findings suggest ways to assist transitioning athletes, such as the use of buddy systems with senior players

WK2060000027).There is growing need for a safe, efficient, specific and non-pathogenic means for delivery of gene therapy materials. Nanomaterials for nucleic acid delivery offer an unprecedented opportunity to overcome these drawbacks; owing to their tunability with diverse physico-chemical properties, they can readily be functionalized with any type of biomolecules/moieties for selective targeting. Nucleic acid therapeutics such as antisense DNA, mRNA, small interfering RNA (siRNA) or microRNA (miRNA) have been widely explored to modulate DNA or RNA expression Strikingly, gene therapies combined with nanoscale delivery systems have broadened the therapeutic and biomedical applications of these molecules, such as bioanalysis, gene silencing, protein replacement and vaccines. Here, we overview how to design smart nucleic acid delivery methods, which provide functionality and efficacy in the layout of molecular diagnostics and therapeutic systems. It is crucial to outline some of the general design considerations of nucleic acid delivery nanoparticles, their extraordinary properties and the structure–function relationships of these nanomaterials with biological systems and diseased cells and tissues.publishersversionpublishe

Crossover from thermal hopping to quantum tunneling in Mn_{12}Ac

The crossover from thermal hopping to quantum tunneling is studied. We show that the decay rate $\Gamma$ with dissipation can accurately be determined near the crossover temperature. Besides considering the Wentzel-Kramers-Brillouin (WKB) exponent, we also calculate contribution of the fluctuation modes around the saddle point and give an extended account of a previous study of crossover region. We deal with two dangerous fluctuation modes whose contribution can't be calculated by the steepest descent method and show that higher order couplings between the two dangerous modes need to be taken into considerations. At last the crossover from thermal hopping to quantum tunneling in the molecular magnet Mn_{12}Ac is studied.Comment: 10 pages, 3 figure

Quantum dynamics of crystals of molecular nanomagnets inside a resonant cavity

It is shown that crystals of molecular nanomagnets exhibit enhanced magnetic relaxation when placed inside a resonant cavity. Strong dependence of the magnetization curve on the geometry of the cavity has been observed, providing evidence of the coherent microwave radiation by the crystals. A similar dependence has been found for a crystal placed between Fabry-Perot superconducting mirrors. These observations open the possibility of building a nanomagnetic microwave laser pumped by the magnetic field
