Dark Matter as a Guide Toward a Light Gluino at the LHC

Motivated by specific connections to dark matter signatures, we study the prospects of observing the presence of a relatively light gluino whose mass is in the range ~(500-900) GeV with a wino-like lightest supersymmetric particle with mass in the range of ~(170-210) GeV. The light gaugino spectra studied here is generally different from other models, and in particular those with a wino dominated LSP, in that here the gluinos can be significantly lighter. The positron excess reported by the PAMELA satellite data is accounted for by annihilations of the wino LSP and their relic abundance can generally be brought near the WMAP constraints due to the late decay of a modulus field re-populating the density of relic dark matter. We also mention the recent FERMI photon constraints on annihilating dark matter in this class of models and implications for direct detection experiments including CDMS and XENON. We study these signatures in models of supersymmetry with non-minimal soft breaking terms derived from both string compactifications and related supergravity models which generally lead to non-universal gaugino masses. At the LHC, large event rates from the three-body decays of the gluino in certain parts of the parameter space are found to give rise to early discovery prospects for the gaugino sector. Excess events at the 5 sigma level can arise with luminosity as low as order 100 pb^{-1} at a center of mass energy of 10 TeV and less than ~ 1 fb^{-1} at a center of mass energy of 7 TeV.Comment: 2 columns, 9 pages, 5 figure caption

De-industrialization: a case study of Dundee, 1951–2001, and its broad implications

Using a case study of one Scottish city, Dundee, this article addresses some of the tensions involved in the use of the concept of ‘de-industrialization’. Widely used to try to understand economic and social change in the post-war years, this term is complex and controversial. This article unravels some of this complexity, arguing that the term is potentially very helpful, but needs careful definition, nuanced application and recognition of its limits. The focus here is on the impact of changing industrial structures on the labour market. After analysing the processes of firm births and deaths, the study looks at the decline of the ‘old staple’ industry, jute manufacturing in Dundee. The next sections assess the role of multinational enterprises in re-shaping the employment structure of the city, before looking at the contraction of some of the city’s other industries. Attention then turns to the impact of all these changes on the economic welfare of the city. The final section draws conclusions about our general understanding of de-industrialization from the Dundee case

A scale of consumer engagement

The practitioner literature is replete with examples of firm efforts to engage consumers. However, the existing relationship marketing constructs focus primarily on customer retention. This research examines those offerings or activities of firms that aim to engage prospects, potentials, customers and their extended relationships, together addressed as consumers in this research. Contributing to the recent efforts to expand the domain of relationship marketing, this research develops the construct of Consumer Engagement, which is the intensity of the consumer's participation and connection with the organization's offerings and/ or its organized activities. Using several qualitative methods, this research develops the construct of Consumer Engagement, differentiating it from existing constructs, such as involvement and customer communities. The qualitative studies in this research show that consumers may be engaged with offerings (e.g. iPod), activities (e.g. Beauty workshops), institutions (Ikea), or brands (e.g. Apple). These offerings/ activities might come from profit-making or non-profit organizations. Engagement might be in the presence or absence of other consumers, and might happen online or offline. Consumers may also be engaged through activities organized by the businesses or by consumers themselves. Using established quantitative scale development procedures, the consumer engagement scale is developed, refined and validated. Consumer Engagement is a three-dimensional, second-order construct, composed of enthusiasm, conscious participation and social interaction. These dimensions are verified using exploratory and confirmatory factor analysis and validated on three different data sets, representing product usage, retail service and activity. The exploration of consumer engagement helps us understand the participation and connection of consumers, independent of their commercial transactions with the company. This research shows that even routine products and brands can engage a consumer, which, in turn, positively influences their connection with the firm, and feelings of goodwill towards and intent to do business with the firm.
