Les forces et les faiblesses de l'indéfini n'importe qui

This paper proposes a semantic analysis of the French free-choice indefinite 'n’importe qui'. The semantics of the indefinite is organised as a ternary structure. The (1) abstract meaning underlies all uses of the item and acts as a principle of creative interpretation generation and comprehension. This principle is actualised via (2) discrete contextual features through to (3) contextual interpretations. Thus, the “existential” reading of 'n’importe qui' is derived by a veridical reading of the arbitrary selection of a qualitatively-marked occurrence from the set of human animates. The derivation of contextual readings from the enrichment by contextual cues of an underspecified meaning has a claim to an explanatory model of the semantics of grammatical polysemous items, and is certainly relevant to model-theoretic approaches in as much as formal semantic notions are intricately linked to the contextual interpretation of items. It is not 'n’importe qui' itself, but its contextual interpretations which may be weak or strong, and an homonymous treatment is not possible given the continuity of the quality and free-choice dimensions from one observed reading of n’importe qui to the next.

La scalarité d'indéfinis à sélection arbitraire

This paper looks at the notion of scale through the negative polarity and free-choice interpretations of arbitrary-selection expressions such as any. These interpretations rest on a scalar model, which explains why they often get associated with the same item cross-linguistically. A scalar model does not seem to emerge readily in the problematic imperatives of the type Pick any card, where the arbitrary selection item differs from its other uses by its existential value and absence of qualitative dimensions. These differences come from a choice over non-distinguishable entities left to the interlocutor. Yet, since this choice is exerted against the whole set of contextual entities, a scalar model seems to stand, for this and other problematic imperative uses.

The relative strength of affective commitment in securing loyalty in service relationships

While commitment is an important antecedent to customer retention, a broad consensus has yet to emerge on the impacts of constituent dimensions of commitment on loyalty in service relationships. This study explores the impacts of affective and continuance commitment on attitudinal and behavioral loyalty in a service context. Since affective commitment is more positive and governed by free choice, whereas continuance commitment is more the result of perceived economic and psychological benefits of being in a relationship, the results of this study suggest that emotional bonds with customers provide a more enduring source of loyalty as compared to economic incentives and switching costs.

Health insurance competition in Germany – the role of advertising

In the 1990s, competition among public health insurance funds (‘sickness funds’) was introduced in Germany. As one means of competition, free choice of initial health funds and subsequent switching between them was made available to all insured. Since then, the number of funds has decreased substantially, and funds have had to engage in competitive strategies to remain in the market. In this paper, we want to analyse the funds' advertising activities in the face of the changed competitive environment. This has not been possible to date due to a lack of data. We use two new datasets to get a first insight into the potential effects of competition on funds' advertising strategies; one of the volume and cost of advertisements and one of their contents. Our results suggest that competition has been associated with an increase in the amount of advertising. As to the adverts themselves, we find that there was a decrease in the share of advertisements of a ‘general’ content in favour of advertisements of a more ‘fund-specific’ content. The data therefore indicate that once the market was open to switching of funds by the insured, funds' advertising efforts changed to differentiating their own perceived strengths from those of competitor funds. These observations allow us to draw some tentative conclusions about the relevance of (attempts of) risk selection by health funds via advertisements and about the general success of the pro-competitive legislation.

Broader or deeper? Exploring the most effective intervention profile for public small business support

Most advanced economies offer publicly financed advice services to start-up firms and SMEs. In England, local or regional Business Links organisations have provided these services, and divided their support into nonintensive one-off contacts providing information or advice and more intensive support involving a diagnostic process and repeated interaction with firms. A key choice for Business Link managers is how to shape their intervention strategies, balancing resources between intensive and nonintensive support. Drawing on resource dependency theory, we develop a typology of intervention strategies for Business Links in England which reflects differences in the breadth and depth of the support provided. We then test the impacts of these alternative intervention models on client companies using both subjective assessments by firms and econometric treatment models that allow for selection bias. Our key empirical result is that Business Links’ choice of intervention strategy has a significant effect both on actual and on perceived business outcomes, with our results emphasising the value of depth over breadth. The implication is that where additional resources are available for business support these should be used to deepen the assistance provided rather than extend assistance to a wider group of firms.

Use of a solvent-free dry matrix coating for quantitative matrix-assisted laser desorption ionization imaging of 4-bromophenyl-1,4-diazabicyclo(3.2.2)nonane-4-carboxylate in rat brain and quantitative analysis of the drug from laser microdissected tissue regions

A dry matrix application for matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI MSI) was used to profile the distribution of 4-bromophenyl-1,4-diazabicyclo(3.2.2)nonane-4-carboxylate, monohydrochloride (BDNC, SSR180711) in rat brain tissue sections. Matrix application involved applying layers of finely ground dry alpha-cyano-4-hydroxycinnamic acid (CHCA) to the surface of tissue sections thaw mounted onto MALDI targets. It was not possible to detect the drug when applying matrix in a standard aqueous-organic solvent solution. The drug was detected at higher concentrations in specific regions of the brain, particularly the white matter of the cerebellum. Pseudomultiple reaction monitoring imaging was used to validate that the observed distribution was the target compound. The semiquantitative data obtained from signal intensities in the imaging was confirmed by laser microdissection of specific regions of the brain directed by the imaging, followed by hydrophilic interaction chromatography in combination with a quantitative high-resolution mass spectrometry method. This study illustrates that a dry matrix coating is a valuable and complementary matrix application method for analysis of small polar drugs and metabolites that can be used for semiquantitative analysis.

Chemistry of phospholipid oxidation

The oxidation of lipids has long been a topic of interest in biological and food sciences, and the fundamental principles of non-enzymatic free radical attack on phospholipids are well established, although questions about detail of the mechanisms remain. The number of end products that are formed following the initiation of phospholipid peroxidation is large, and is continually growing as new structures of oxidized phospholipids are elucidated. Common products are phospholipids with esterified isoprostane-like structures and chain-shortened products containing hydroxy, carbonyl or carboxylic acid groups; the carbonyl-containing compounds are reactive and readily form adducts with proteins and other biomolecules. Phospholipids can also be attacked by reactive nitrogen and chlorine species, further expanding the range of products to nitrated and chlorinated phospholipids. Key to understanding the mechanisms of oxidation is the development of advanced and sensitive technologies that enable structural elucidation. Tandem mass spectrometry has proved invaluable in this respect and is generally the method of choice for structural work. A number of studies have investigated whether individual oxidized phospholipid products occur in vivo, and mass spectrometry techniques have been instrumental in detecting a variety of oxidation products in biological samples such as atherosclerotic plaque material, brain tissue, intestinal tissue and plasma, although relatively few have achieved an absolute quantitative analysis. The levels of oxidized phospholipids in vivo is a critical question, as there is now substantial evidence that many of these compounds are bioactive and could contribute to pathology. The challenges for the future will be to adopt lipidomic approaches to map the profile of oxidized phospholipid formation in different biological conditions, and relate this to their effects in vivo. This article is part of a Special Issue entitled: Oxidized phospholipids-their properties and interactions with proteins.
