This study provides the first systematic account of word-final cluster acquisition in bilingual children. To this end, forty Welsh–English bilingual children differing in language dominance and age (; to ;) participated in a picture-naming task in English and Welsh. The results revealed significant age and dominance effects on cluster acquisition, with greater overall accuracy on the Englis...

In traditional auctions, it is often assumed that bidders are a homogenous group. However, since most online bidders are average consumers instead of professional bidders, we suspect that online bidders are a heterogeneous group. The purpose of this paper is to explore the types of online bidders based on their real bidding behaviors in a popular auction site. A cluster analysis is employed and...

A new method which allows identifying any shape of cluster patterns in case of numerical clustering is proposed. The method is based on the iterative clustering construction utilizing a nearest neighbor distance between clusters to merge. The method differs from other techniques of which the cluster density is determined based on calculating the variance factors. The cluster density proposed he...

Cornelian cherry is one of the most important small fruits in Arasbaran region, with wide applications in medicines and food products. In this study, the relationship among 28 quantitative and qualitative traits related to fruit, leaf, tree, and flower of 20 cornelian cherry genotypes was evaluated. Significant positive as well as negative correlations were found among some important quantitati...

Seeds of 200 accessions of alfalfa (Medicago sativa L.) were provided from Iraniannatural resource gene bank and were sown as drilled plot using alpha designs/unreplicatedwith 2 repeated entries within all of 10 blocks under dry land farming system in agriculturalresearch center of Hamadan, Iran during 2009 to 2010. The data were collected and analyzedfor plant height, stem number, leaf stem ra...

Genetic  diversity  is  the  basis  of  the  natural  evolution  of  plant  breeding  and  biological  system  are  important  components  of  sustainability. The aim of this study was to evaluate 116 genotypes of Triticum turgidum from seven countries in terms of morphological traits. The results showed that high significant differences among the genotypes. The correlation between gra...

Many polymorphisms exist in field bindweed (Convolvulus arvensis L.) populations. These differences that appear especially in their flower and leaf cause to different biotypes of this weed that are different in view of dry weight, rate- and flowering period. This research was accomplished during 2005 to 2006 at Weed Research Department, Iranian Plant Protection Research Institute for identifica...

Rapid population growth as well as agricultural and industrial development have increased the contamination of Iranian rivers. This study utilized principal components analysis (PCA) to determine the degree of significance of qualitative parameters of water resources in the Karkheh River in southwestern Iran. Cluster analysis (CA) grouped the monitoring stations based on the water quality data ...

Hot pepper (Capsicum spp.) is an economically important spice widely cultivated and consumed in Ethiopia. In spite of its wide importance, there is no information available on the molecular genetic diversity of this crop. Cultivars characterization is an important link between the conservation and utilization of plant genetic resources in various breeding programs. Using five ISSR prim...
