Training Japanese listeners to identify English /r/ and /l/: A first report

Abstract: Native speakers of Japanese learning English generally have difficulty differentiating the phonemes /r/ and /l/, even after years of experience with English. Previous research that attempted to train Japanese listeners to distinguish this contrast using synthetic stimuli reported little success, especially when transfer to natural tokens containing /r/ and /l/ was tested. In the present study, a different training procedure that emphasized variability among stimulus tokens was used. Japanese subjects were trained in a minimal pair identification paradigm using multiple natural exemplars contrasting /r/ and /l/ from a variety of phonetic environments as stimuli. A pretest‐posttest design containing natural tokens was used to assess the effects of training. Results from six subjects showed that the new procedure was more robust than earlier training techniques. Small but reliable differences in performance were obtained between pretest and posttest scores. The results demonstrate the importance of stimulus ...

Protocol-based computer reminders, the quality of care and the non-perfectability of man.

Abstract: To determine whether clinical errors can be reduced by prospective computer suggestions about the management of simple clinical events, I studied the responses of nine physicians to computer suggestions generated by 390 protocols in a controlled crossover design. These protocols dealt primarily with conditions managed (e.g., elevated blood pressure) or caused (e.g., liver toxicity) by drugs. Physicians responded to 51 per cent of 327 events when given, and 22 per cent of 385 events when not given computer suggestions. Neither level of postgraduate training (first-year postgraduate or third-year post-graduate) nor the order in which physicians served as study and control subjects had statistically significant overall effect on the results. It appears that the prospective reminders do reduce errors, and that many of these errors are probably due to man's limitations as a data processor rather than to correctable human deficiencies.

Remarkable archaeal diversity detected in a Yellowstone National Park hot spring environment

Abstract: Of the three primary phylogenetic domains--Archaea (archaebacteria), Bacteria (eubacteria), and Eucarya (eukaryotes)--Archaea is the least understood in terms of its diversity, physiologies, and ecological panorama. Although many species of Crenarchaeota (one of the two recognized archaeal kingdoms sensu Woese [Woese, C. R., Kandler, O. & Wheelis, M. L. (1990) Proc. Natl. Acad. Sci. USA 87, 4576-4579]) have been isolated, they constitute a relatively tight-knit cluster of lineages in phylogenetic analyses of rRNA sequences. It seemed possible that this limited diversity is merely apparent and reflects only a failure to culture organisms, not their absence. We report here phylogenetic characterization of many archaeal small subunit rRNA gene sequences obtained by polymerase chain reaction amplification of mixed population DNA extracted directly from sediment of a hot spring in Yellowstone National Park. This approach obviates the need for cultivation to identify organisms. The analyses document the existence not only of species belonging to well-characterized crenarchaeal genera or families but also of crenarchaeal species for which no close relatives have so far been found. The large number of distinct archaeal sequence types retrieved from this single hot spring was unexpected and demonstrates that Crenarchaeota is a much more diverse group than was previously suspected. The results have impact on our concepts of the phylogenetic organization of Archaea.

Development of a Scale to Measure Memorable Tourism Experiences

Abstract: The quality experiences provided to customers, which are indeed memorable, directly determine a business’s ability to generate revenue (Pine and Gilmore 1999). However, the extant tourism literature has provided limited explanation of the factors that characterize memorable tourism experiences. Thus, the goal of the present study was to develop a valid and reliable measurement scale that will assist in understanding the concept and in improving the effective management of the memorable experience. Following Churchill’s (1979) recommended process, we developed a 24-item memorable tourism experience scale that we believe is applicable to most destination areas. The scale comprises seven domains: hedonism, refreshment, local culture, meaningfulness, knowledge, involvement, and novelty. The data support this dimensional structure of the memorable tourism experience as well as its internal consistency and validity (i.e., content, construct, convergent, and discriminant validity). Theoretical and managerial imp...

Do Politically Connected Boards Affect Firm Value

Abstract: This article explores whether political connections are important in the United States. The article uses an original hand-collected data set on the political connections of board members of S&P 500 companies to sort companies into those connected to the Republican Party and those connected to the Democratic Party. The analysis shows a positive abnormal stock return following the announcement of the nomination of a politically connected individual to the board. This article also analyzes the stock-price response to the Republican win of the 2000 presidential election and finds that companies connected to the Republican Party increase in value, and companies connected to the Democratic Party decrease in value.
