Over the past 40 years, extensive research has examined the effectiveness of mnemonics for vocabulary learning. Much of this research has investigated the keyword method (Atkinson & Raugh, 1975), which involves linking an image related to a to-be-learned L2 word with an image related to a similar-sounding L1 word. Whereas most research has shown the keyword method to be effective (Webb & Nation, 2017) with impressive long-term retention rates (Beaton, Gruneberg, & Ellis, 1995), some have questioned its usefulness, particularly due to the quality of the resulting lexical representations and extended latencies associated with recall (Barcroft, Sommers, & Sunderman, 2011; Van Hell & Candia Mahn, 1997). Other drawbacks of the keyword technique are the equating of dissimilar L1 and L2 phonemes and the difficulty in creating associations for languages with markedly different phoneme inventories. The current study presents a novel approach called the Homonym/Homophone Association Method (HAM). It overcomes some of the drawbacks of the keyword method by associating meanings of L2 homonyms or homophones, one known by the learner and one unknown. Because the pronunciations of the L2 target words are identical (or nearly identical), learners only need to associate two distinct meanings. A quasi-experiment (N = 71) employing a within-subjects design compared the effectiveness of (1) HAM using researcher-generated associations and images, (2) HAM using self-generated associations, and (3) production practice that involved writing target words in sentences. Results on an unannounced posttest given 3 weeks after instruction suggest an advantage for HAM using researcher-generated associations.

Abstract. A long-term priming experiment examined the way stress information is processed and represented in French speakers’ mind. Repeated prime and target words either matched (/bãˈ do/ – /bãˈ do/ “headband”) or mismatched their stress pattern (/bãdo/ – /bãˈ do/). In comparison to a control condition (/maʁ[Formula: see text]/ – /bãˈ do/), the results showed that matching and mismatching primes were equally effective in facilitating the processing of the target words. Thus, despite the fact that French speakers routinely produce and hear words in their stressed and unstressed versions, this study suggests that stress in French is not integrated into lexical representations.

Various agencies have begun to research and introduce performance-related specifications (PRS) for the design of modern asphalt paving mixtures. The focus of most recent studies has been directed toward simplified cracking test development and evaluation. In some cases, development and validation of PRS has been performed, building on these new tests, often by comparison of test values to accelerated pavement test studies and/or to limited field data. This study describes the findings of a comprehensive research project conducted at Illinois Tollway, leading to a PRS for the design of mainline and shoulder asphalt mixtures. A novel approach was developed, involving the systematic establishment of specification requirements based on: 1) selection of baseline values based on minimally acceptable field performance thresholds; 2) elevation of thresholds to account for differences between short-term lab aging and expected long-term field aging; 3) further elevation of thresholds to account for variability in lab testing, plus variability in the testing of field cores; and 4) final adjustment and rounding of thresholds based on a consensus process. After a thorough evaluation of different candidate cracking tests in the course of the project, the Disk-shaped Compact Tension—DC(T)—test was chosen to be retained in the Illinois Tollway PRS and to be presented in this study for the design of crack-resistant mixtures. The DC(T) test was selected because of its high degree of correlation with field results and its excellent repeatability. Tailored Hamburg rut depth and stripping inflection point thresholds were also established for mainline and shoulder mixes.

Despite the importance of obtaining a university degree, retention rates remain a concern for many universities. This longitudinal study provides a multi-domain examination of first-year student characteristics and behaviors that best predict which students graduate. Graduation status was assessed seven years after students entered university. Participants (N = 1017; 71% female; mean age in Year 1 was 19 years) enrolled in a Canadian mid-sized university completed a survey, provided their enrollment status over the next 6 years (regardless of whether they left university), and consented to have their grades and status provided by the Registrar. Overall, 79% of students graduated by Year 7 (44% in 4 years). The strongest predictor of graduation was first-year grades. Social engagement in the university also predicted graduation. Surprisingly, mental health was not a significant predictor of graduation. Only a minority of students may experience mental health difficulties to such an extent that it affects their ability to succeed at university.

ABSTRACTThe interface between Hg1-xCdxTe(0 ≦ x ≦ 1) and Hg1-yCdyTe(0 ≦ y ≦ 1) epitaxial layers of different composition (x ≠ y) is unstable with regard to the intermixing of the Hg and Cd cations within the Group II sublattice. This phenomenon may give rise to long-term stability problems in HgTe-(Hg,Cd)Te superlattices and composition grading between (Hg,Cd)Te absorber layers and CdTe buffer or passivation layers in epitaxial infra red detectors. In this paper, a novel approach to the inhibition of interdiffusion in these systems is discussed. This involves the growth of an intervening ZnTe barrier layer at the heterointerface between two (Hg,Cd)Te layers. Initial results are presented which indicate the effectiveness of this technique in reducing interdiffusion in an experimental heterostructure grown by MOVPE. Some possible applications in a variety of HgTe-based long wavelength devices are discussed.

Using a task which closely simulated the actual output from a sonar device, the performance of 12 subjects was observed for a total of 115 hr in repeated prolonged monitoring sessions under auditory, visual, and dual-mode display conditions. Despite an underlying basic superiority of signal discriminability on the visual display, and the occurrence of long-term practice effects, detection rate was consistently and substantially higher under the auditory condition, and higher again with the dual-mode display. These results are similar to those obtained by earlier workers using artificial laboratory tasks for shorter periods, and are consistent with the notion that auditory displays have greater attention-gaining capacity in a “vigilance” situation. A further comparison of the auditory and visual displays was then made in an “alerted” situation, where the possible occurrence of a signal was indicated by a warning stimulus in the alternative sensory mode. Ten subjects were observed for a total of 57 hr in these conditions, under which performance was found to be clearly superior with the visual display. Cross-modal correlations of performance indicated the presence of a common factor of signal detectability within subjects. It was concluded that where efficiency both in the initial detection of targets and their subsequent identification and tracking are equally important, the best solution would seem to be to retain both auditory and visual displays and to ensure that these are monitored concurrently.
