This corridor passes through an area which is prone to landslides, especially during the wet season. This, in turn, influences the traffic and has detrimental effects to the local economy, as it is dependent mainly on tourism and commercial transportation by road. This paper will focus on the landslides which occurred between June and September 2018, within the Bay of Plenty East on the north side of the Raukumara Peninsula. The paper will analyze both the nature and triggering mechanisms behind these landslides. As the landslides occur in the wet season, rainfall has been commonly considered the main trigger. However, the paper will argue that vehicle vibrations have been contributing to the instability of the slopes within the Bay of Plenty East. This paper will be instrumental in developing future transportation strategies in this part of the North Island.展开更多

The growth dynamics of fruit showed that the two cultivars performed similar changes with their fresh weight volume and structure, it included the first slow growth stage, the rapid growth stage and the second solw growth stage. The fruit was a typical polyachene with a ovule which belonged to a Poligonum type, the growth process of pollen tube from stigma to embryo sac was clearly observed by flourescence microscopy. Embryo development was similar to that of most dicotyls, and the mature embryo was orthotropous; Endosperm development was a nuclear type, and gradually disappeared with development:Seed coat consisted of 34 layer cells, and pericarp was composed of 68 layer cells which differentiated from ovary wall cell; The structure of receptacle was a typical stem which consisted of epidermis ,cortex and vascular cylinder.

However, what commonly revealed by most studies is that there is a positive correlation between the use of language learning strategy and language learners' performance. This paper applies Dornyei's classification, known as cognitive strategies, metacognitive strategies, social strategies and affective strategies. By reviewing previous studies on the application of metacognitive strategy in English as a second language(ESL) reading comprehension, plenty of useful implications for reading pedagogy are suggested. It further explains how certain important metacognitive strategies, namely Semantic Mapping(SM) and Experience-Text-Relationship(ETR), can be implemented in second language reading comprehension, aiming to encourage language learners to be aware of learning strategies,"learn how to learn"(Cohen, 1988, p66)!展开更多
