Sale the seven Cs: Teaching/training aid for the (e-)retail mix

The ‘4Ps’ of the marketing mix have long been popular with students, tutors, trainers and practitioners as a learning and teaching aid. The purpose of this paper is to present an equivalent tool for retail and e-retail: ‘Sale the 7Cs’. The approach is by reference to other authors’ versions of the marketing, retail and e-retail mixes, distilled into a simplified framework: C1 Convenience; C2 Customer value and benefit; C3 Cost to the customer; C4 Computing and category management; C5 Customer franchise; C6 Customer care and service; C7 Communication and customer relationships. This simplified mnemonic is new for (e-)retail. Mini case examples are used to illustrate the applicability. These have a practical value for trainers and educators as specimen answers to activity exercises. Retailers may find the convenient 7Cs structure useful when planning strategies and tactics

A CNL for Contract-Oriented Diagrams

We present a first step towards a framework for defining and manipulating normative documents or contracts described as Contract-Oriented (C-O) Diagrams. These diagrams provide a visual representation for such texts, giving the possibility to express a signatory's obligations, permissions and prohibitions, with or without timing constraints, as well as the penalties resulting from the non-fulfilment of a contract. This work presents a CNL for verbalising C-O Diagrams, a web-based tool allowing editing in this CNL, and another for visualising and manipulating the diagrams interactively. We then show how these proof-of-concept tools can be used by applying them to a small example

ALMA observations of the supergiant B[e] star Wd1-9

Mass-loss in massive stars plays a critical role in their evolution, although the precise mechanism(s) responsible – radiatively driven winds, impulsive ejection and/or binary interaction – remain uncertain. In this Letter, we present Atacama Large Millimetre/Submillimeter Array line and continuum observations of the supergiant B[e] star Wd1-9, a massive post-main-sequence object located within the starburst cluster Westerlund 1 (Wd1). We find it to be one of the brightest stellar point sources in the sky at millimetre wavelengths, with (serendipitously identified) emission in the H41α radio recombination line. We attribute these properties to a low velocity (∼100 km s-1 ) ionized wind, with an extreme mass-loss rate ≳6.4 × 105(d/5 kpc)1.5 Mȯyr-1. External to this is an extended aspherical ejection nebula indicative of a prior phase of significant mass-loss. Taken together, the millimetre properties of Wd1-9 show a remarkable similarity to those of the highly luminous stellar source MWC349A. We conclude that these objects are interacting binaries evolving away from the main sequence and undergoing rapid case-A mass transfer. As such they – and by extension the wider class of supergiant B[e] stars – may provide a unique window into the physics of a process that shapes the life-cycle of ∼70 per cent of massive stars found in binary systems

Excavations at Tas-Silg, Malta : a preliminary report on the 1996-1998 campaigns conducted by the Department of Classics and Archaeology of the University of Malta

The area known as Tas-Silg is situated in the south-eastern part of the island of Malta, close to Marsaxlokk harbour. In reality the place name refers to the small church dedicated to Our Lady of the Snows (hence Tas-Silg) situated at the point where the narrow · road from Zejtun forks out in two directions: to Delimara and Xrobb il-Ghagin due south-east and to Marsaxlokk village due south-west. A British-period fort occupying the highest point of the elongated hill further south along· the first road also carries the same place name. The lower and more compact hill on which the excavations have been conducted is called 'Ta' Berikka' , but since it is so close to the above-mentioned church (only 50 m to the north) the tradition of calling it Tas-Silg is now well established and there is no sense in changing it. The site has a commanding view of the Marsaxlokk harbour to the south and overlooks two other bays, Marsascala and St Thomas's bay, to the north-east. On all sides the slope is broken up by man-made terraced fields There is no doubt that the topography of the site must have been a determining factor in its choice for the establishment of a religious centre in the Temple period of Maltese pehistory (3000--2500 BC), though one must keep in mind that close to Tas-Silg there are three other prehistoric temple sites. each one with a completely different topography. The Temple people were quite introverted in their cultural isolation and do not seem to have been much interested in seafaring and in the outside world. The situation changed radically in the following age, the Bronze Age. when the island was occupied by people who set up villages on naturally defensible hilltops, occasionally fortifying them with artificial ramparts. The Tas-Silg hill with its temple ruins was occupied by these people, but it is not as yet clear for what purpose. The scenario changed again in historical times when the central and western Mediterranean started to be parcelled out among the commercial powers originating in the eastern Mediterranean. The Greeks do not seem to have even tried 10 colonize Malta as they did in neighbouring Sicily. The Phoenicians, however, did occupy the island, apparently through a slow process of peaceful penetration and eventual political and cultural assimi lation. It was in this period that the ruins of the megalithic temple were transformed into a Phoenician extraurban shrine dedicated to Astarte, which in time expanded into a full y-fledged sanctuary with an international reputation. The last chapter in the millennia- long history of the site was written when the colonnaded courtyard in front of the old temple was transformed into an early Christian church. Any use made of the site in the following Arab period is, once again, poorly understood.peer-reviewe

Thermodynamics of an attractive 2D Fermi gas

Thermodynamic properties of matter are conveniently expressed as functional relations between variables known as equations of state. Here we experimentally determine the compressibility, density and pressure equations of state for an attractive 2D Fermi gas in the normal phase as a function of temperature and interaction strength. In 2D, interacting gases exhibit qualitatively different features to those found in 3D. This is evident in the normalized density equation of state, which peaks at intermediate densities corresponding to the crossover from classical to quantum behaviour.Comment: Contains minor revision

Walking as a meaningful leisure occupation: the implications for occupational therapy

Introduction: In response to growing interest in leisure in occupational therapy and the importance of understanding how occupations maintain, enhance and promote health and wellbeing, a qualitative phenomenological study was conducted to explore the experiences of walking for leisure. Method: Six healthy student participants, identified as regular walkers, were interviewed using a semi-structured format. Data were analysed following interpretative phenomenological analysis methodology. Findings: Participants expressed how and why walking was meaningful to them; the four main themes were social connectedness, wellbeing, connection to nature and achievement from a challenge. Findings suggest that occupational therapists could use walking and leisure occupations in intervention, and that there is scope for an occupational therapy perspective in health promotion. Conclusion: Determining the subjective meaning of engaging in walking as a leisure occupation has implications for occupational science and health promotion in helping to explain why people do what they do

Lymphocytes of BRCA1 and BRCA2 germ-line mutation carriers, with or without breast cancer, are not abnormally sensitive to the chromosome damaging effect of moderate folate deficiency

Mutations in BRCA1 and BRCA2 genes may cause defective DNA repair and increase risk for breast cancer. Folate deficiency is associated with increased breast cancer risk and induces chromosome abnormalities. We hypothesised that BRCA1 and BRCA2 germ-line mutation carriers are more sensitive to the genome damaging effect of folate deficiency compared to healthy non-carrier controls and that this sensitivity is further increased in those carriers who develop breast cancer. We tested these hypotheses in lymphocytes cultured in medium containing 12 nM or 120 nM folic acid (FA) for 9 days and measured proliferative capacity and chromosomal instability using the cytokinesis-block micronucleus (CBMN) assay. BRCA1 and BRCA2 mutation carriers with or without breast cancer were not abnormally sensitive to FA deficiency-induced chromosome instability however BRCA2 mutation carriers had significantly reduced cell proliferation. FA deficiency reduced cell proliferation and increased micronucleus formation significantly accounting for 45-59% and 70-75% of the variance in these parameters compared to 0.3-8.5% and 0.2-0.3% contributed by BRCA1 or BRCA2 mutation carrier status respectively. The results of this study suggest that moderate folate deficiency has a stronger effect on chromosomal instability than BRCA1 or BRCA2 mutations found in breast cancer families.Sasja Beetstra, Carolyn Salisbury, Julie Turner, Meryl Altree, Ross McKinnon, Graeme Suthers and Michael Fenec
