Three different types of ion-supported TEMPO catalysts are synthesized and their catalytic activity in the chemoselective oxidation of alcohols is investigated. These new catalysts show high catalytic activity in water and can be reused for the next run by extraction of products. Recycling experiments exhibit that ion-supported TEMPO can be reused up to five times without loss of catalytic acti...

Perception experiments for Bari and Pisa Italian showed that listeners can reliably distinguish between final and non-final utterances in discourse by means of intonation. Bari listeners were also able to distinguish a third category, signa lling that the end of the discourse unit is approaching (penultimate position). This was not the case for Pisa listeners, although there was possibly an eff...

Many scattering models have been proposed in the graphics literature. Few of them, however, have been evaluated through comparisons with real measured data. As the demand for plausible and predictable scattering models increases, more effort is focused on performing such comparisons, which require the use of measurement devices. Once the accuracy of a given model is determined, data can be extr...

This paper revisits the status of long-distance intermediate-scope readings of indefinites (Kratzer 1998, Schwarz 2001, Endriss 2009, among others). An experimental study with native English speakers investigates two questions: whether intermediate-scope readings are distinct from functional readings; and whether there is any difference in the availability of functional readings to a indefinite...

This paper examines the foreign accent in Brazilian Portuguese and Japanese. In the first experiment, Japanese speech samples of Japanese-descent Brazilians were compared to those of native Japanese speakers, as evaluated by Japanese, and in the second experiment, Portuguese speech samples of native Japanese speakers were compared to those of Japanesedescent Brazilians, as evaluated by Brazilia...

Electric footshock elicited an immediate burst of activity followed by a period of immobility termed freezing. Naloxone, an opiate antagonist, enhanced both of these postshock reactions (Experiment 1). Naloxone's effects on the active and inactive components of the postshock reaction paralleled those of increasing shock intensity (Experiment 2). This finding suggests that the drug caused these ...

Identiiable parametrizations for direct adaptive control of linear multivariable plants, which assume exact knowledge of the systems observability indices and the full interactor, have been reported in the literature recently. The observability indices have no clear physical meaning, hence it is not obvious how they can be obtained in practical applications. Also, assuming the interactor is kno...

Research on binocular rivalry and motion direction discrimination suggests that stochastic activity early in visual processing influences the perception of ambiguous stimuli. Here, we extend this to higher level tasks of word and face processing. In Experiment 1, we used blocked gender and word discrimination tasks, and in Experiment 2, we used a face versus word discrimination task. Stimuli we...

Many adolescents in Sweden speak Swedish with what appears to be a foreign accent. Whereas some people perceive their way of speaking Swedish as the result of imperfect or incomplete learning of Swedish, others argue that they speak a new variety of Swedish. In this paper, several arguments of anecdotal character are tested experimentally in order to investigate whether or not a new variety of ...

The purpose of this study was to determine if submaximal exercise resulted in increased levels of attention in young students. The participants were fourth grade students from a local elementary school. There were 27 total participants – 16 were in the exercise group, and 11 were in the control, or rest, group. Each student took two distractibility tests within an hour and a half. In between th...
