From theory to impact: bringing work-life initiatives into the mainstream
In this special issue we focus on the work and influence of Sue Lewis, one of the Community, Work and Family’s two founding editors. In launching this journal Sue, together with Carolyn Kagan, aimed to encourage debate and critical examination of, and reflection on, existing perspectives, frameworks and practices (Kagan and Lewis, 2015). They also explicitly aimed “to publish work that challenged the status quo, encouraged personal reflection and reflexivity, and put professional and lay views side by side” (Kagan and Lewis, 2015). For this special issue we invited researchers who have worked with Sue at different stages of her career – from her Ph.D. supervisor (Cary Cooper), some of her international research partners (Marcie Pitt-Catsouphes, Ellen Kossek), her previous colleagues at Manchester Metropolitan University (Carolyn Kagan, Rebecca Lawthom), her national and international research partners on a series of European projects (Julia Brannen, Ann Nilsen, Laura den Dulk, Bram Peper), through to one of Sue’s former Ph.D. students and colleague at Middlesex University (Uracha Chatrakul Na Ayudhya) and early career researchers (Sweta Rajan-Rankin). In the articles that are to follow, the authors draw upon and highlight the considerable and invaluable influences that Sue’s work has had in the field of Community, Work and Family
Large structures and tethers working group
The Large Structures and Tethers Working Group sought to clarify the meaning of large structures and tethers as they related to space systems. Large was assumed to mean that the characteristic length of the structure was greater than one of such relevant plasma characteristics as ion gyroradius or debey length. Typically, anything greater than or equal to the Shuttle dimensions was considered large. It was agreed that most large space systems that the tether could be better categorized as extended length, area, or volume structures. The key environmental interactions were then identified in terms of these three categories. In the following Working Group summary, these categories and the related interactions are defined in detail. The emphasis is on how increases in each of the three spatial dimensions uniquely determine the interactions with the near-Earth space environment. Interactions with the environments around the other planets and the solar wind were assumed to be similar or capable of being extrapolated from the near-Earth results. It should be remembered in the following that the effects on large systems do not just affect specific technologies but will quite likely impact whole missions. Finally, the possible effects of large systems on the plasma environment, although only briefly discussed, were felt to be of potentially great concern
Parameters for a Super-Flavor-Factory
A Super Flavor Factory, an asymmetric energy e+e- collider with a luminosity
of order 10^36 cm-2s-1, can provide a sensitive probe of new physics in the
flavor sector of the Standard Model. The success of the PEP-II and KEKB
asymmetric colliders in producing unprecedented luminosity above 10^34 cm-2s-1
has taught us about the accelerator physics of asymmetric e+e- colliders in a
new parameter regime. Furthermore, the success of the SLAC Linear Collider and
the subsequent work on the International Linear Collider allow a new
Super-Flavor collider to also incorporate linear collider techniques. This note
describes the parameters of an asymmetric Flavor-Factory collider at a
luminosity of order 10^36 cm-2s-1 at the Upsilon(4S) resonance and about 10^35
cm-2s-1 at the Tau production threshold. Such a collider would produce an
integrated luminosity of about 10,000 fb-1 (10 ab-1) in a running year (10^7
sec) at the Upsilon(4S) resonance.Comment: Flavor Physics & CP Violation Conference, Vancouver, 200
Report of the 2005 Snowmass Top/QCD Working Group
This report discusses several topics in both top quark physics and QCD at an
International Linear Collider (ILC). Issues such as measurements at the
threshold, including both theoretical and machine requirements, and
the determination of electroweak top quark couplings, are reviewed. New results
concerning the potential of a 500 GeV collider for measuring
couplings and the top quark Yukawa coupling are presented. The status of higher
order QCD corrections to jet production cross sections, heavy quark form
factors, and longitudinal gauge boson scattering, needed for percent-level
studies at the ILC, are reviewed. A new study of the measurement of the
hadronic structure of the photon at a collider is presented. The
effects on top quark properties from several models of new physics, including
composite models, Little Higgs theories, and CPT violation, are studied.Comment: 39 pages, many figs; typos fixed and refs added. Contributed to the

Measuring the quantum efficiency of single radiating dipoles using a scanning mirror
Using scanning probe techniques, we show the controlled manipulation of the
radiation from single dipoles. In one experiment we study the modification of
the fluorescence lifetime of a single molecular dipole in front of a movable
silver mirror. A second experiment demonstrates the changing plasmon spectrum
of a gold nanoparticle in front of a dielectric mirror. Comparison of our data
with theoretical models allows determination of the quantum efficiency of each
radiating dipole.Comment: 4 pages, 4 figure
The Rising Light Curves of Type Ia Supernovae
We present an analysis of the early, rising light curves of 18 Type Ia
supernovae (SNe Ia) discovered by the Palomar Transient Factory (PTF) and the
La Silla-QUEST variability survey (LSQ). We fit these early data flux using a
simple power-law to determine the time of first
light , and hence the rise-time from first light to
peak luminosity, and the exponent of the power-law rise (). We find a mean
uncorrected rise time of days, with individual SN rise-times
ranging from to days. The exponent n shows significant
departures from the simple 'fireball model' of (or ) usually assumed in the literature. With a mean value of , our data also show significant diversity from event to event. This
deviation has implications for the distribution of 56Ni throughout the SN
ejecta, with a higher index suggesting a lesser degree of 56Ni mixing. The
range of n found also confirms that the 56Ni distribution is not standard
throughout the population of SNe Ia, in agreement with earlier work measuring
such abundances through spectral modelling. We also show that the duration of
the very early light curve, before the luminosity has reached half of its
maximal value, does not correlate with the light curve shape or stretch used to
standardise SNe Ia in cosmological applications. This has implications for the
cosmological fitting of SN Ia light curves.Comment: 19 pages, 19 figures, accepted for publication in MNRA
WEXTOR: A Web-based tool for generating and visualizing experimental designs and procedures
WEXTOR is a Javascript-based experiment generator and teaching tool on the World-Wide Web that can be used to design laboratory and Web experiments in a guided step-by-step process. It dynamically creates the customized Web pages and Javascripts needed for the experimental procedure and provides experimenters with a print-ready visual display of their experimental design. WEXTOR flexibly supports complete and incomplete factorial designs with between-subjects, within-subjects, and quasiexperimental factors, as well as mixed designs. The software implements client-side response time measurement
and contains a content wizard for creating interactive materials, as well as dependent measures (graphical scales, multiple-choice items, etc.), on the experiment pages. However, it does not aim to replace a full-fledged HTML editor. Several methodological features specifically needed in Web experimental design have been implemented in the Web-based tool and are described in this paper. WEXTOR
is platform independent. The created Web pages can be uploaded to any type of Web server in which data may be recorded in logfiles or via a database. The current version of WEXTOR is freely available for educational and noncommercial purposes. Its Web address is http://www.genpsylab.unizh.ch/wextor/index.html
Recent Development on Underground Coal Gasification and Subsequent CO2 Storage
Underground coal gasification (UCG) is the in-situ conversion of deep underground coal to synthesis gas for heating, chemical manufacturing and power generation. UCG has been the subject of extensive pilot testing but technical and environmental concerns remain, not least its greenhouse gas emissions. An attractive solution is to combine UCG with CO2 capture and storage (CCS) so that the CO2 generated from the UCG and combustion of synthesis gas is re-injected back underground in the UCG cavities, adjacent unmineable coal seams and stressed strata. Thereby the emissions from UCG are eliminated and deep coal reserves become a new source of energy supply. This paper reviews the recent global development of UCG projects, the research progress of UCG technology and the technical developments and economic feasibility of UCG-CCS in recent EU projects
