These complexes were subsequently mass isolated in a quadrupole ion trap mass spectrometer and then irradiated by the tunable infrared output of a free electron laser in the 800-1600 cm−1 range. From the frequency dependence of the fragmentation of the complexes, vibrational signatures of the complexes were obtained. Computational work carried out in parallel reveals that the complexes formed are very strongly bound and are among the most strongly bound complexes of Na+ and Cl− ever observed with molecular species. The dipole moment calculated for the heaxafluorocyclohexane is very large (~7 D) and it appears that the bonding in each of the complexes has a significant electrostatic contribution.PostprintPeer reviewe

Star Architects, Urban Spectacles and Global Brands: Exploring the Case of the Tokyo Olympics 2020

Olympic stadia are often regarded as a political showcase involving a range of influences: the host nation’s international politics, the interests of transnational capitalism along with site-specific meanings and the power of iconic architecture. By examining the 2020 Tokyo Olympic main stadium as a case study, the paper analyzes the controversial Zaha Hadid’ stadium plan in relation to the Japanese nation branding initiative. In doing so, the paper argues that ‘branding’ should be seen as part of an economic and cultural system which seems to enhance the global value of iconic architects and their buildings. Yet, the power of brands can be understood as a contingent entity. This is because its ambivalenct nature entails a tension between exclusiveness and banality; additionally, it could be difficult for branded architects to work across the different regimes of global and local politics; and they are of course also constrained by the logic of neoliberal transnational capitalism. By investigating a major global branded architect, Zaha Hadid and her architecture plan, the paper considers why a new image of Japan could not be adequately created by Hadid’s aesthetics and narratives of the Olympic stadium which should be regarded as a national cultural legacy. The paper then discusses the contested processes of image-making and narrative creation in relation to the representation of Japan in contemporary Olympic culture. The paper concludes with an examination of Kengo Kuma’s architecture language in his 2020 Tokyo Olympics stadium design

Subaltern geographies: Geographical knowledge and postcolonial strategy

In recent years a small but rich geographical literature has engaged with Subaltern Studies to explore the geographical and geopolitical imaginations of subaltern subjects and groups. Such writings have deployed subalternity to designate a substantive subject or group marginalized in the face of power. Departing from this, the paper instead treats subalternity more figuratively, as a word able to evoke spatialities occluded by the Euro-American power that haunts disciplinary geography. The paper argues that using subalternity like this holds the potential to pluralize geographical interventions, particularly in the light of the discipline's materialist turns since the late 1990s. To make this argument, the paper engages Gayatri Spivak's seminal critique of the Subaltern Studies collective, suggesting how this might speak productively to a postcolonial geographical methodology. It demonstrates the potential of this methodology by weaving it through a broader attempt to critically engage the politics of nature and environment in Sri Lanka

How Hot Are Your Ions in Differential Mobility Spectrometry?

This document is the unedited Author’s version of a Submitted Work that was subsequently accepted for publication in 'Journal of the American Society for Mass Spectrometry', copyright © American Chemical Society after peer review. To access the final edited and published work see https://doi.org/10.1021/jasms.9b00043Ions can experience significant field-induced heating in a differential mobility cell. To investigate this phenomenon, the fragmentation of several para-substituted benzylpyridinium “thermometer” ions (R = OMe, Me, F, Cl, H, CN) was monitored in a commercial differential mobility spectrometer (DMS). The internal energy of each benzylpyridinium derivative was characterized by monitoring the degree of fragmentation to obtain an effective temperature, Teff, which corresponds to a temperature consistent with treating the observed fragmentation ratio using a unimolecular dissociation rate weighted by a Boltzmann distribution at a temperature T. It was found that ions are sufficiently thermalized after initial activation from the ESI process to the temperature of the bath gas, Tbath. Once a critical field strength was surpassed, significant fragmentation of the benzylpyridinium ions was detected. At the maximum bath gas temperature (450 K) and separation voltage (SV; 4400 V) for our instrument, Teff for the benzylpyridinium derivatives ranged from 664 ± 9 K (p-OMe) to 759 ± 17 K (p-H). The extent of activation at a given SV depends on the ion’s mass, degrees of freedom, (NDoF), and collision frequency as represented by the ion’s collision cross section. Plots of Teff vs the product of ion mass and NDoF and the inverse of collision cross section produce strong linear relationships. This provides an attractive avenue to estimate ion temperatures at a given SV using only intrinsic properties. Moreover, experimentally determined Teff correlate with theoretically predicted Teff using with a self-consistent method based on two-temperature theory. The various instrumental and external parameters that influence Teff are additionally discussed.WSH would like to acknowledge the financial support provided by the Natural Sciences and Engineering Research Council (NSERC) of Canada, the Ontario Centres of Excellence in the form of a VIP-II grant, as well as the government of Ontario for an Ontario Early Researcher Award.

Lifestyle travellers: Backpacking as a way of life

Scholarship on backpackers speculates some individuals may extend backpacking to a way of life. This article empirically explores this proposition using lifestyle consumption as its framing concept and conceptualises individuals who style their lives around the enduring practice of backpacking as ‘lifestyle travellers’. Ethnographic interviews with lifestyle travellers in India and Thailand offer an emic account of the practices, ideologies and social identity that characterise lifestyle travel as a distinctive subtype within backpacking. Departing from the drifter construct, which (re)constitutes this identity as socially deviant, the concept of lifestyle allows for a contemporary appraisal of these individuals’ patterns of meaningful consumption and wider insights into how ongoing mobility can lead to different ways of understanding identities and relating to place. Keywords: lifestyle consumption; backpacker; mobility; drifter; identit

Civil Society, Everyday Life and the Possibilities for Development Studies

Civil society is one of the most contentious terms in political thought. There is considerable, and highly significant, difference between academic debate about the meaning of ‘civil society’ and the way the term is mobilized in international development discourse. In particular, narratives of civil society in international development are often dominated by reference to organizational descriptions and measurability. But I would like to suggest here that the term should be reclaimed as a way of giving meaning to the stories of the everyday lives of the people who create, shape and embody civil society. Used in this way, the idea of civil society can be understood as intersecting emotions, discourses and practices and can add to the body of scholarly work that nurtures and values everyday life as a lens through which to view wider social processes. Paying attention to the everyday life of civil society may have implications for that way the civil society is engaged with academically, and also has the potential to refresh how civil society is thought about in development practice

The Lives of Young Fathers: A Review of Selected Evidence

While young fathers have been neglected in social research in the UK, over the past fifteen years a small but growing body of empirical evidence has emerged across a range of studies. This review article draws selectively on this literature to document the characteristics of young fathers in the UK and their lived experiences. It presents compelling evidence for the desire of young fathers to be engaged as parents, despite the sometimes multiple challenges that they face. The article begins with a demographic profile of young fathers and documents what is known of young fathers’ relationships with their children, the child's mother and wider kin. It goes on to consider a range of practical issues facing young fathers. The article concludes with a consideration of young fathers’ support needs and experiences of professional support, drawing out the implications for policy and professional practice

The structures and properties of anionic tryptophan complexes

The physicochemical properties of [Trpn–H]− and [Trpn⋯Cl]− (n = 1, 2) have been investigated in a combined computational and experimental infrared multiple dissociation (IRMPD) study. IRMPD spectra within the 850–1900 cm−1 region indicate that deprotonation is localized on the carboxylic acid moiety in [Trpn–H]− clusters. A combination of hydrogen bonding and higher order charge–quadrupole interactions appear to influence cluster geometries for all investigated systems. Calculated global minimum and low energy geometries of [Trp⋯Cl]− and [Trp2⋯Cl]− clusters favour coordination of the halide by the indole NH. [Trp2–H]− and [Trp2⋯Cl]− exhibit additional π–π interactions between the heterocyclic side chains.The authors would like to acknowledge the financial support provided by the Natural Sciences and Engineering Research Council (NSERC) of Canada

Engaging fathers in child welfare services: a narrative review of recent research evidence

It is widely recognized as problematic that there are generally low levels of engagement with child welfare services from biological and social fathers. The result can be limited resources for children's care and potentially poor risk assessment and management. This paper reviews the published research from 2000 to 2010 about the barriers to and facilitators of better father engagement, as well as the very limited evidence on the effectiveness of work with maltreating fathers. There is relatively little known about what works in engaging men, but there are some promising indicators from family support and child protection practice contexts. These include early identification and early involvement of fathers; a proactive approach, including an insistence on men's involvement with services; and the use of practical activities. In the light of what is known about the characteristics of maltreating fathers, there is a logical fit with cognitive‐behavioural approaches. Although there is no direct evidence of the effectiveness of motivational interviewing in this context, its effectiveness in allied fields of practice would suggest that it may hold some promise for the initial engagement of fathers who pose a risk to children.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/90556/1/j.1365-2206.2012.00827.x.pd
