How brand portfolios have changed:a study of grocery suppliers brands from 1994 to 2004

This study examines the changes in brand structures based on a repeat audit of brand portfolios by leading grocery product suppliers. It compares results from content analyses of four hundred leading suppliers' brands sold to Tesco and Sainsbury's in 1994 and 2004. The brand structures used have changed although not uniformly in extent or direction. There is now more complexity in the way brand names are used. An extended typology of brand structures is incorporated. Propositions drawn from latest thinking on the use of brand portfolios are compared with the findings implications discussed.

Should I stay or should I go? Explaining turnover intentions with organizational identification and job satisfaction

The social identity approach is a powerful theoretical framework for the understanding of individuals behaviour. The main argument is that individuals think and act on behalf of the group they belong to because this group membership adds to their social identity, which partly determines ones self-esteem. In the organizational world, social identity and self-categorization theories state that a strong organizational identification is associated with low turnover intentions. Because identification is the more general perception of shared fate between employee and organization, we propose that the relationship between identification and turnover will be mediated by job satisfaction as the more specific evaluation of ones task and working conditions. In four samples we found organizational identification feeding into job satisfaction, which in turn predicts turnover intentions.

Fixed or variable noise in contrast discrimination? The jury's still out

The ability to distinguish one visual stimulus from another slightly different one depends on the variability of their internal representations. In a recent paper on human visual-contrast discrimination, Kontsevich et al (2002 Vision Research 42 1771 - 1784) re-considered the long-standing question whether the internal noise that limits discrimination is fixed (contrast-invariant) or variable (contrast-dependent). They tested discrimination performance for 3 cycles deg-1 gratings over a wide range of incremental contrast levels at three masking contrasts, and showed that a simple model with an expansive response function and response-dependent noise could fit the data very well. Their conclusion - that noise in visual-discrimination tasks increases markedly with contrast - has profound implications for our understanding and modelling of vision. Here, however, we re-analyse their data, and report that a standard gain-control model with a compressive response function and fixed additive noise can also fit the data remarkably well. Thus these experimental data do not allow us to decide between the two models. The question remains open. [Supported by EPSRC grant GR/S74515/01]

Organic reactions in ionic liquids: a simple highly regioselective or regiospecific substitutions of benzotriazole

In the absence of any added base in ionic liquids [Bmim][BF4], benzotriazole replaces the halogen atom of an a-halogenated ketone or a-halogenated carboxylic ester to give the corresponding N-1-substituted benzotriazole as the only isomer, and 1-chloro-2,4-dinitrobenzene reacted similarly with benzotriazole to afford the N-1-substituted benzotriazole in a good yield. Alkyl halides reacted regioselectively to afford the N-1-alkylbenzotriazole in ratios of more than 15 to 1 over the N-2-isomer.

Party servants, ideologues or regional representatives? The German Länder and the reform of federalism

This article considers recent attempts to reform German federalism, the failed 2004 reform, and the reforms agreed in 2006 and 2009. It compares partisan, ideological and territorial factors which contribute to an understanding of reform, finding that all three have a role in explaining actors’ views of reform proposals. Two other claims are developed: that in some aspects of the reforms, a division between ‘generalist’ and ‘subject specialist’ politicians became apparent; and that a decisive change between 2004 and 2006 was the formation of a grand coalition at a federal level, which paved the way for agreement upon reform proposals.

Persistence of apoptotic cells without autoimmune disease or inflammation in CD14-/- mice

Interaction of macrophages with apoptotic cells involves multiple steps including recognition, tethering, phagocytosis, and anti-inflammatory macrophage responses. Defective apoptotic cell clearance is associated with pathogenesis of autoimmune disease. CD14 is a surface receptor that functions in vitro in the removal of apoptotic cells by human and murine macrophages, but its mechanism of action has not been defined. Here, we demonstrate that CD14 functions as a macrophage tethering receptor for apoptotic cells.Significantly, CD14-/- macrophages in vivo are defective in clearing apoptotic cells in multiple tissues, suggesting a broad role for CD14 in the clearance process. However, the resultant persistence of apoptotic cells does not lead to inflammation or increased autoantibody production, most likely because, as we show, CD14-/- macrophages retain the ability to generate anti-inflammatory signals in response to apoptotic cells. We conclude that CD14 plays a broad tethering role in apoptotic cell clearance in vivo and that apoptotic cells can persist in the absence of proinflammatory consequences.

The association between the use of IP by UK SMEs in 2001 and subsequent performance in 2002 to 2004

This report analyses the 2001 cohort of UK SMEs. The specific focus is on the link between IP activity in 2001 and subsequent performance (to 2004). The 2001 cohort contains 130,082 SMEs of which 3,123 were IP active (2.4%). Specifically, 1,872 SMEs had at least one UK trade mark publication; 697 had one or more Community trade mark registrations; 646 SMEs had one or more UK patents; and 443 had one or more EPO patent publications. The outcome and financial performance of the SMEs is analysed in various ways. Initially, we look at the determinants of survival to 2004. We then look at growth of assets and turnover for the period 2001 to 2004.
