The Life and Death of a Metaphor, or the Metaphysics of Metaphor

This paper addresses two issues: (1) what it is for a metaphor to be either alive or dead and (2) what a metaphor must be in order to be either alive or dead. Both issues, in turn, bear on the contemporary debate whether metaphor is a pragmatic or semantic phenomenon and on the dispute between Contextualists and Literalists. In the first part of the paper, I survey examples of what I take to be live metaphors and dead metaphors in order to establish that there is a phenomenon here to be explained. I then propose an explanation of metaphorical vitality (and by implication of metaphorical death) in terms of the dependence of the interpretation of a metaphor on a family or network of expressions specific to its context of utterance. I then argue that only a Literalist account of metaphor — one that posits metaphorical expressions (a la Stern (2000))—and not Contextualist and Gricean approaches can accommodate this explanation. Finally, I discuss some objections to my Literalist account and sketch an explanation of types to counter Platonistic objections to my metaphorical expression types

Quotations as Pictures

The proposal of a semantics for quotations using explanatory notions drawn from philosophical theories of pictures. In Quotations as Pictures, Josef Stern develops a semantics for quotations using explanatory notions drawn from philosophical theories of pictures. He offers the first sustained analysis of the practice of quotation proper, as opposed to mentioning. Unlike other accounts that treat quotation as mentioning, Quotations as Pictures argues that the two practices have independent histories, that they behave differently semantically, that the inverted commas employed in both mentioning and quotation are homonymous, that so-called mixed quotation is nothing but subsentential quotation, and that the major problem of quotation is to explain its dual reference or meaning—its ordinary meaning and its metalinguistic reference to the quoted phrase attributed to the quoted subject. Stern argues that the key to understanding quotation is the idea that quotations are pictures or have a pictorial character. As a phenomenon where linguistic competence meets a nonlinguistic symbolic ability, the pictorial, quotation is a combination of features drawn from the two different symbol systems of language and pictures, which explains the exceptional and sometimes idiosyncratic data about quotation. In light of this analysis of verbal quotation, in the last chapters Stern analyzes scare quotation as a nonliteral expressive use of the inverted commas and explores the possibility of quotation in pictures themselves

Receptor for advanced glycation end products (RAGE) regulates sepsis but not the adaptive immune response

This is the publisher's version, also available electronically from http://www.jci.org/articles/view/18704While the initiation of the adaptive and innate immune response is well understood, less is known about cellular mechanisms propagating inflammation. The receptor for advanced glycation end products (RAGE), a transmembrane receptor of the immunoglobulin superfamily, leads to perpetuated cell activation. Using novel animal models with defective or tissue-specific RAGE expression, we show that in these animal models RAGE does not play a role in the adaptive immune response. However, deletion of RAGE provides protection from the lethal effects of septic shock caused by cecal ligation and puncture. Such protection is reversed by reconstitution of RAGE in endothelial and hematopoietic cells. These results indicate that the innate immune response is controlled by pattern-recognition receptors not only at the initiating steps but also at the phase of perpetuation

Safety of Whey basic protein isolates as a novel food pursuant to Regulation (EU) 2015/2283

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver an opinion on whey basic protein isolate as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is obtained by ion exchange chromatography of skimmed cow's milk. The applicant intends to market the NF in infant and follow-on formulae and meal replacement beverages, dietary foods for special medical purposes and as food supplements. The highest estimated intake of the NF based on the proposed uses and use levels would be 24.8 mg/kg body weight (bw) per day in infants and 27.8 in toddlers. The information provided on composition, specifications, production process and stability of the NF do not raise safety concerns. Taking into account the composition of the NF and the intended use levels, the Panel considers that the consumption of the NF is not nutritionally disadvantageous. The Panel considers that there is no concern with respect to genotoxicity. The no observed adverse effect level (NOAEL) of a subchronic 13-week rat study was 2000 mg/kg bw per day. Considering the source, the production process and nature of the NF, the Panel considers the margin of exposure (MOE) of 154 to be sufficient for the adult population (on a high-estimated intake of 13 mg/kg bw). For infants and toddlers, the MOE would be at least 81 and 72, respectively. Taking into account the composition of the NF, its source, the history of consumption of the main components of the NF, the production process and that the NOAEL in a subchronic rat study was the highest dose tested the Panel considers that also the MOE for infants and toddlers are sufficient. The Panel concludes that the novel food ingredient, whey basic protein isolate, is safe under the proposed uses and use levels. (C) 2018 European Food Safety Authority.

Safety of Allanblackia seed oil for extended uses in vegetable oils and milk and in yellow fat and cream-based spreads up to 30% (w/w)

In 2007, the EFSA NDA Panel concluded that Allanblackia seed oil obtained from the seeds of Allanblackia trees is safe for human consumption under the proposed conditions of use. Due to its high contents of stearic-oleic-stearic and stearic-oleic-oleic triglycerides, which made the oil suitable as a ‘hardstock’ component, the applicant applied for its use as a novel food (NF) ingredient in yellow fat and cream-based spreads at a level of 20% (w/w). In this application, the applicant seeks (1) to increase the authorised maximum use level (i.e. 20% w/w) in yellow fat spreads and cream-based spreads to 30% (w/w) and (2) the use of this NF in mixes of vegetable oils and milk up to a maximum use level of 30% (w/w). (3) The applicant proposes also some changes in the specifications of the NF, although he noted that the oil is collected, extracted and refined using the same processes that are currently used for other edible vegetable oils and which have been evaluated in the original application assed by EFSA in 2007. According to the information provided by the applicant, the production process and the composition of the NF do not change. The Panel notes that the revised specification limits on trans-fatty acid (TFA), unsaponifiable matter, peroxide value are similar to those for other edible oils and fats. The applicant also indicated that he had performed an updated comprehensive literature search using several different databases, but no preclinical studies or human studies on Allanblackia seed oil were identified which have not been provided for the previous EFSA assessment in 2007. The Panel notes that the proposed extended uses would increase the potential intake of the NF, which is considered not to be nutritionally disadvantageous. The Panel concludes that Allanblackia seed oil is safe at the extended uses and use level

Safety of xylo-oligosaccharides (XOS) as a novel food pursuant to Regulation (EU) 2015/2283

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver a scientific opinion on a mixture of xylo-oligosaccharides (XOS) as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is obtained from corncobs (Zea mays subsp. mays) via enzyme-catalysed hydrolysis and subsequent purification. The main components of the NF, the oligosaccharides, are resistant to human digestive enzymes and are fermented by colonic bacteria. The intention is to add the NF to a variety of foods such as bakery and dairy products, fruit jelly, chocolates and soy-drinks. The information provided on composition, specifications, production process and stability of the NF, does not raise safety concerns. There were effects observed in the animal studies with the NF or with other XOS which were considered by the Panel to be expected from the intake of non-digestible carbohydrates. The Panel notes that the acute and transient gastrointestinal observed in human intervention studies with the NF or with other XOS have also been associated with the consumption of other non-digestible carbohydrates. The Panel concludes that the NF, a mixture of XOS, is safe under the proposed uses and use levels. The target population is the general population. (C) 2018 European Food Safety Authority.

Safety of egg membrane hydrolysate as a novel food pursuant to Regulation (EU) 2015/2283

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver a scientific opinion on egg membrane hydrolysate as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is a water-soluble hydrolysate of egg membrane, produced by alkaline treatment of the thin layer lining the shells of chicken eggs. The main constituents of the NF are elastin, collagen and glycosaminoglycans. The information provided on the production process, batch-to-batch variability, composition and specifications of the NF is sufficient and does not raise safety concerns. The NF is proposed to be used as a food supplement for adults, at a maximum daily amount of 450 mg. The consumption of the NF is not nutritionally disadvantageous. One human study, which was not designed for safety but included a number of endpoints pertaining to safety, did not raise safety concerns. The Panel considers that taking into account the information provided and considering the nature, the source and the production process of the NF, there are no safety concerns for the NF at the proposed conditions of use. The Panel concludes that the NF, egg membrane hydrolysate, is safe as a food supplement at a dose of 450 mg/day. The target population for the NF is the general adult population.

Safety of shrimp peptide concentrate as a novel food pursuant to Regulation (EU) 2015/2283

Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver an opinion on shrimp peptide concentrate as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is a peptide mixture obtained by an enzymatic proteolysis from northern shrimp (Pandalus borealis) shells and heads. The information provided on the composition, specifications, batch-to-batch variability, stability and production process of the NF is sufficient and does not raise safety concerns. The intention of the applicant is to use this NF as an ingredient in food supplements and to market it to adult consumers at a maximum proposed level of intake of 1,200 mg/day (corresponding to 17 mg/kg body weight (bw) per day for a 70 kg person). There are no concerns with regard to genotoxicity. The available human data do not raise safety concerns. Considering the no observed adverse effect level (NOAEL) of 2,000 mg/kg bw per day from a 90-day repeated-dose oral toxicity study, the maximum proposed level of intake and the nature of the NF, the Panel concludes that the margin of exposure (of 117) is sufficient. The Panel concludes that the NF, shrimp peptide concentrate, is safe to be used as a food supplement at the proposed maximum dose of 1,200 mg/day. The target population is adults. The Panel considered that the conclusion on the safety of the NF could not have been reached without the data from the unpublished study report on repeated-dose 90-day oral toxicity and from the unpublished study reports on two human studies.
