Abstract The study of iconic properties of language has been marginalized in linguistics, with the assumption that iconicity, linked with expressivity, is external to the grammar. Yet iconicity plays an essential role in sociolinguistic variation. At a basic level, repetition and phonetic intensification can intensify the indexicality of variables. Iconicity plays a further role in variation in the form of sound symbolism, linking properties of sounds with attributes or objects. Production studies have shown some phonological variables exhibiting sound symbolism, particularly in the expression of affect. In some cases, the observation of sound symbolism has been largely interpretive. But in others, stylistic variability as a function of speaker affect has provided empirical evidence of iconicity. This article examines the role of iconicity and performativity in transcending the limits of reference, reviews iconicity in production studies, and provides experimental evidence that sound symbolism influences how listeners attribute affect to linguistic variation.

The Ideal

Recent work by party scholars reveals a widening gap between the normative ideals we set out for political parties and the empirical evidence that reveals their deep and perhaps insurmountable shortcomings in realizing these ideals. This disjunction invites us to consider the perspective of David Hume, who offers a theory of the value and proper function of parties that is resilient to the pessimistic findings of recent empirical scholarship. I analyze Hume's writings to show that the psychological experience of party informs the opinions by which governments can be considered legitimate. Hume thus invites us to consider the essential role parties might play in securing legitimacy as that ideal is practiced or understood by citizens, independent of the ideal understandings of legitimacy currently being articulated by theorists. My analysis contributes to both recent party scholarship and to our understanding of the role of parties in Hume's theory of allegiance.

The Cost

Willingness-to-pay (WTP) values and willingness-to-accept (WTA) values have received considerable attention, but the role of reference-dependence effects is more diverse. Policies involving cost and risk may have reference point effects with respect to both cost and risk, leading to four potential valuation measures. Experimental evidence for water quality policies suggests that the cost reference effects are particularly influential in that context. There is, however, no evidence of significant reference effects for labor market estimates of the value of a statistical life. Sound application of benefit values other than WTP measures requires pertinent empirical evidence and an assessment of the underlying rationality of the determinants of the reference-dependence effects.

AbstractA coherent framework for addressing risk arising from new technologies is needed. In proposing a framework of broad application and future focus, where empirical evidence is scarce, reliance on strong theory becomes all the more important. Some technologies are more prone to excessive engagement than others (i.e. more addictive). Some users are also more susceptible to excessive engagement than others. Impulsivity theory emphasises the importance of reinforcement magnitude in determining the risk associated with a new technology, and that an individual's sensitivity to reinforcement (reward drive) and capacity to inhibit previously reinforced behaviour (rash impulsiveness) determines their susceptibility to problematic engagement. Online gaming provides a good example of how such theory can be applied to facilitate intervention efforts and develop policy.

Non-arbitrary sound-shape correspondences (SSC), such as the “bouba-kiki” effect, have beenconsistently observed across languages and together with other sound-symbolic phenomena challenge the classic linguistic dictum of the arbitrariness of the sign. Yet, it is unclear what makes a sound “round” or “spiky” to the human mind. Here we tested the hypothesis that visual experience is necessary for the emergence of SSC, supported by empirical evidence showing reduced SSC in visually impaired people. Results of two experiments comparing early blind and sighted individuals showed that SSC emerged strongly in both groups. Experiment 2, however, showed a partially different pattern of SSC in sighted and blind, that was mostly explained by a different effect of orthographic letter shape: The shape of written letters (spontaneously activated by spoken words) influenced SSC in the sighted, but not in the blind, who are exposed to an orthography (Braille) in which letters do not have spiky or round outlines. In sum, early blindness does not prevent the emergence of SSC, and differences between sighted and visually impaired people may be due the indirect influence (or lack thereof) of orthographic letter shape.

SummarySynthetic peptides (TRAP or Thrombin Receptor Activating Peptide) corresponding to at least the first five aminoacids of the new N-terminal tail generated after thrombin proteolysis of its receptor are effective to mimic thrombin. We have studied two different TRAPs (SFLLR, and SFLLRN) in their effectiveness to induce the different platelet responses in comparison with thrombin. Using Indo-1/AM- labelled platelets, the maximum rise in cytoplasmic ionized calcium was lower with TRAPs than with thrombin. At threshold concentrations allowing maximal aggregation (50 μM SFLLR, 5 μM SFLLRN and 1 nM thrombin) the TRAPs-induced release reaction was about the same level as with thrombin, except when external calcium was removed by addition of 1 mM EDTA. In these conditions, the dense granule release induced by TRAPs was reduced by over 60%, that of lysosome release by 75%, compared to only 15% of reduction in the presence of thrombin. Thus calcium influx was more important for TRAPs-induced release than for thrombin-induced release. At strong concentrations giving maximal aggregation and release in the absence of secondary mediators (by pretreatment with ADP scavengers plus aspirin), SFLLRN mobilized less calcium, with a fast return towards the basal level and induced smaller lysosome release than did thrombin. The results further demonstrate the essential role of external calcium in triggering sustained and full platelet responses, and emphasize the major difference between TRAP and thrombin in mobilizing [Ca2+]j. Thus, apart from the proteolysis of the seven transmembrane receptor, another thrombin binding site or thrombin receptor interaction is required to obtain full and complete responses.

Induced Aggregation

SummaryThe hypothesis that platelet ADP is responsible for collagen-induced aggregation has been re-examined. It was found that the concentration of ADP obtaining in human PRP at the onset of aggregation was not sufficient to account for that aggregation. Furthermore, the time-course of collagen-induced release in human PRP was the same as that in sheep PRP where ADP does not cause release. These findings are not consistent with claims that ADP alone perpetuates a collagen-initiated release-aggregation-release sequence. The effects of high doses of collagen, which released 4-5 μM ADP, were not inhibited by 500 pM adenosine, a concentration that greatly reduced the effect of 300 μM ADP. Collagen caused aggregation in ADP-refractory PRP and in platelet suspensions unresponsive to 1 mM ADP. Thus human platelets can aggregate in response to collagen under circumstances in which they cannot respond to ADP. Apyrase inhibited aggregation and ATP release in platelet suspensions but not in human PRP. Evidence is presented that the means currently used to examine the role of ADP in aggregation require investigation.
