Online learning is increasingly being used in K-12 learning environments. A concomitant trend is found towards learning becoming authentic as students learn with tasks that are connected to realworld occupations. In this study, 48 pre-service teachers use an online environment to engage in authentic practice as they developed online learning experiences for their future students. Using a design...

AIM To report a study conducted to test a model linking authentic leadership of managers with nurses' perceptions of structural empowerment, performance, and job satisfaction. BACKGROUND Authentic leadership has been proposed as the root element of effective leadership needed to build healthier work environments because there is special attention to the development of empowering leader-follow...

DNA from fossil human bones could provide invaluable information about population migrations, genetic relations between different groups and the spread of diseases. The use of ancient DNA from bones to study the genetics of past populations is, however, very often compromised by the altered and degraded state of preservation of the extracted material. The universally observed postmortem degrada...

Students studying foreign languages often wish to enjoy authentic foreign-language content for example, foreign-language videos and comics. Existing means of presenting this content, however, are suboptimal from the perspective of language learning. We have developed a pair of tools that aim to help learners acquire the foreign language while enjoying authentic, foreignlanguage material. One to...

Ancient DNA (aDNA) research has long depended on the power of PCR to amplify trace amounts of surviving genetic material from preserved specimens. While PCR permits specific loci to be targeted and amplified, in many ways it can be intrinsically unsuited to damaged and degraded aDNA templates. PCR amplification of aDNA can produce highly-skewed distributions with significant contributions from ...

Despite the enormous potential of analyses of ancient DNA for phylogeographic studies of past populations, the impact these analyses, most of which are performed with fossil samples from natural history museum collections, has been limited to some extent by the inefficient recovery of ancient genetic material. Here we show that the standard storage conditions and/or treatments of fossil bones i...

In the previous paper (Matsumoto et al., 1987), pharmacological evidence for secretion of serotonin (5-HT) by cultured sympathetic principal neurons was reported. Here, we present further evidence that 5-HT is a transmitter of some of these neurons under certain culture conditions, and can also be a "false" transmitter. Sympathetic principal neurons, dissociated from superior cervical ganglia (...

Rice fermented with the mold Monascus purpureus, also known as the red yeast rice (RYR) used in traditional Chinese medicine, contains pharmacologically important monacolins. The prescription statin, lovastatin, is identical to monacolin K, and there is a suspicion of spiking RYR products with lovastatin. Profiling authentic and raw RYR samples has the potential to distinguish the spiked from n...
