Naming Latencies

To investigate decision level processes involved in bilingual word recognition tasks, Dutch–English participants had to name Dutch–English homographs in English. In a stimulus list containing items from both languages, interlingual homographs yielded longer naming latencies, more Dutch responses, and more other errors in both response languages if they had a high-frequency Dutch reading. Dutch naming latencies were slower than or equally slow as English naming latencies. In a stimulus list containing only English words and homographs, there was no homograph effect in naming latencies, although homographs did elicit more errors than control words. The results are interpreted as the consequence of list-induced variability in the competition between lexical items of the two languages involved. In addition, two additional decision processes have to be assumed: a language check, and a response deadline for non-target-language responses.

Interlingual Homographs

We contrasted the effect of instruction-induced expectancies and language intermixing in an English lexical decision task performed by Dutch–English bilinguals. At the start of the experiment, participants were instructed to respond to interlingual homographs and exclusively English words by giving a “yes” response, and to English non-words and exclusively Dutch words by giving a “no” response. In the first part of the experiment the stimulus list did not contain any Dutch words. In the second part of the experiment, Dutch items were introduced. No significant differences were found between interlingual homographs and controls in the first part of the experiment, while strong inhibition effects were obtained for interlingual homographs in the second part. These results indicate that language intermixing rather than instruction-based expectancies drives the bilingual partipants' performance. Consequences for current views on bilingual word recognition are discussed.

Naming Latencies

This study investigated whether bilinguals simultaneously activate phonological representations from both of their languages when reading words in just one. The critical stimuli were interlingual homographs (e.g., PAIN) that were low in frequency in the target language of the study (English) and high in frequency in the nontarget language (French). Both English-French and French-English bilinguals were tested. In each experiment, participants named a block of English experimental words, a block of French filler words, and then a second block of English experimental words. In the first block of English trials, the English-French bilinguals had similar naming latencies for homographs and English-only control words, although they made more errors on homographs. In contrast, the French-English bilinguals showed a homograph disadvantage in both the latency and error data. In the second block of English trials, both the English-French bilinguals and the French-English bilinguals showed homograph interference on latency and error measures. We interpret these results as indicating that the activation of phonological representations can appear to be both language-specific and nonspecific, depending on the characteristics of the bilingual and whether they have recently named words in the nontarget language.

Specific Impact

This article has been published in Acta Psychologica. Cognates share their form and meaning across languages: “winter” in English means the same as “winter” in Dutch. Research has shown that bilinguals process cognates more quickly than words that exist in one language only (e.g. “ant” in English). This finding is taken as strong evidence for the claim that bilinguals have one integrated lexicon and that lexical access is language non-selective. Two English lexical decision experiments with Dutch-English bilinguals investigated whether the cognate facilitation effect is influenced by stimulus list composition. In Experiment 1, the ‘standard’ version, which included only cognates, English control words and regular non-words, showed significant cognate facilitation (31 ms). In contrast, the ‘mixed’ version, which also included interlingual homographs, pseudohomophones (instead of regular non-words) and Dutch-only words, showed a significantly different profile: a non-significant disadvantage for the cognates (8 ms). Experiment 2 examined the specific impact of these three additional stimuli types and found that only the inclusion of Dutch words significantly reduced the cognate facilitation effect. Additional exploratory analyses revealed that, when the preceding trial was a Dutch word, cognates were recognised up to 50 ms more slowly than English controls. We suggest that when participants must respond ‘no’ to non-target language words, competition arises between the ‘yes’- and ‘no’-responses associated with the two interpretations of a cognate, which (partially) cancels out the facilitation that is a result of the cognate’s shared form and meaning. We conclude that the cognate facilitation effect is a real effect that originates in the lexicon, but that cognates can be subject to competition effects outside the lexicon.

Deformation Modes

The cycle configuration at two-frequency loading regimes depends on the number of parameters including the absolute values of the frequencies and amplitudes of the low-frequency and high-frequency loads added during this mode, the ratio of their frequencies and amplitudes, as well as the phase shift between these harmonic components, the latter having a significant effect only with a small ratio of frequencies. Presence of such two-frequency regimes or service loading conditions for parts of machines and structures schematized by them can significantly reduce their endurance. Using the results of experimental studies of changes in the endurance of a two-frequency loading of specimens of cyclically stable, cyclically softened and cyclically hardened steels under rigid conditions we have shown that decrease in the endurance under the aforementioned conditions depends on the ratio of frequencies and amplitudes of operation low-frequency low-cycle and high-frequency vibration stresses, and, moreover, the higher the level of the ratios of amplitudes and frequencies of those stacked harmonic processes of loading the greater the effect. It is shown that estimation of such a decrease in the endurance compared to a single frequency loading equal in the total stress (strains) amplitudes can be carried out using an exponential expression coupling those endurances through a parameter (reduction factor) containing the ratio of frequencies and amplitudes of operation cyclic loads and characteristic of the material. The reduction is illustrated by a set of calculation-experimental curves on the corresponding diagrams for each of the considered types of materials and compared with the experimental data.

Multiple Case

The front end of projects is strategically important; yet, how project concepts are identified, evaluated, and selected at the pre-project stage is poorly understood. This article reports on an inductive multiple-case study of how executives made such decisions in major upstream oil and gas projects. The findings show that in such a high-risk context, often an experienced executive makes these decisions alone and he creates value by facilitating growth. We identified three value-creating decision processes that varied by the executives’ risk approach and decision context. These processes depart from the formal project management prescriptions and the strategic decision-making literature.

The most important role of ultrasound (US) in the management of gallbladder (GB) lesions is to detect lesions earlier and differentiate them from GB carcinoma (GBC). To avoid overlooking lesions, postural changes and high-frequency transducers with magnified images should be employed. GB lesions are divided into polypoid lesions (GPLs) and wall thickening (GWT). For GPLs, classification into pedunculated and sessile types should be done first. This classification is useful not only for the differential diagnosis but also for the depth diagnosis, as pedunculated carcinomas are confined to the mucosa. Both rapid GB wall blood flow (GWBF) and the irregularity of color signal patterns on Doppler imaging, and heterogeneous enhancement in the venous phase on contrast-enhanced ultrasound (CEUS) suggest GBC. Since GWT occurs in various conditions, subdividing into diffuse and focal forms is important. Unlike diffuse GWT, focal GWT is specific for GB and has a higher incidence of GBC. The discontinuity and irregularity of the innermost hyperechoic layer and irregular or disrupted GB wall layer structure suggest GBC. Rapid GWBF is also useful for the diagnosis of wall-thickened type GBC and pancreaticobiliary maljunction. Detailed B-mode evaluation using high-frequency transducers, combined with Doppler imaging and CEUS, enables a more accurate diagnosis.
