Teachers and learners of Chinese therefore use a Romanisation system, pinyin, for representing the sound of each character. Dual Coding Theory (DCT; Paivio, 1991) and Ehri’s (1992) theory of word learning indicate that knowledge of a word’s orthographic representation in a shallow-depth orthography such as pinyin should reinforce the phonological form of that word in the learner’s memory. On the other hand, pedagogists are divided concerning whether extensive use of pinyin helps or hinders learners’ ability to recall meanings of vocabulary presented only in Chinese characters (Xing, 2009; Packard, 1990). This dissertation presents the results of a cross-sectional study examining the relationship between proficiency in pinyin and the ability to recall meanings of vocabulary items presented aurally on one hand, and in characters on the other. 71 students of Chinese at an independent school in England were tested on their vocabulary recall knowledge and their accuracy in pinyin transcription. They were also asked about the strategies they used for learning vocabulary and their attitudes towards pinyin. The results showed that firstly, most participants made extensive use of pinyin when learning new vocabulary, regardless of teaching methodology in their class. Secondly, there was a significant, medium correlation between pinyin ability and knowledge of vocabulary encountered aurally, consistent with DCT and Ehri’s (1992) theory of word learning. This does not necessarily indicate a cause-effect relationship, however, and could be due to the positive effects of second language phonological awareness on both skills. Finally, there was no correlation between pinyin proficiency and character recognition. Thus a higher ability in pinyin appears to neither help nor hinder the acquisition of the orthographic form of new vocabulary in L2 Chinese.

Among the vines in Mayan homegardens in Yucatán is the pitahaya (<i>Hylocereus undatus</i>), a cactus with edible fruit. We use this species as a model to identify changes in the level of knowledge and management of homegardens due to modernization (increased tourism, paved roads, and urban expansion) in order to propose conservation strategies. Structured interviews were carried out in 100 homegardens; information regarding economics, language, school attendance, and the distance to cities were gathered. Currently, pitahaya is mostly eaten as a sorbet, and women harvest its fruit more often than men do. It is the elderly who teach the next generations about the use and care of pitahayas. The model that best explained the level of knowledge and m...
