With the rapid proliferation of user-generated content available on the Internet, one of the biggest challenges is determining the relevancy of the information shown. The content often comes in two camps: ephemeral or evergreen. Evergreen content such as recipes for carrot cake or intro to data structures frequently don’t change with time, whereas ephemeral content, such as celebrity hot or not...

New Zealand shares a common problem with other countries: a shortage of blood donors. Approximately 4% of New Zealand’s total population donate blood, yet up to 20% may need to receive donated blood or blood products. However, there has been little success in accurately predicting willingness to donate blood, and greater knowledge is needed of those variables most likely to predict potential do...

Pricing Prototypical Products When we think of colas, Coca-Cola first comes to mind. Products such as Cola-Cola, Tide laundry detergent and Chapstick lip balm are the prototypical products in their respective categories. Over three decades, research in consumer psychology has accumulated evidence on how prototypicality structures memory, shapes the composition of consideration set and influence...

seed deterioration is loss of seed quality, viability and vigor due to effect of adverse environmental factors. many of our crops are reproduced through seeds, and throughout the world large quantities are produced, stored and transported. seed ageing during storage may cause retardation of field establishment, and may eventually result in seedling abnormalities or even failure of emergence. du...

one of the most common methods for conservation of plant genetic resources is their ex situ storage as seed gene banks. seeds that are stored in the gene banks must be regenerated due to exchange and seed deterioration; if they not be regenerated the potential benefits of infrastructure investments for germplasm ex situ conservation may not be attained. prediction of seed longevity is based on ...

Online communities suffer serious newcomer attrition. This paper explores whether and how early activity diversity – the degree to which a newcomer engages in a wide range of a site’s activities in the first session – is associated with their longevity. We introduce a metric (DSCORE) to characterize early activity diversity in online sites and run our analyses on an online community ‘MovieLens’...

Climate change affects the abundance, distribution and activity of natural enemies that are important for suppressing herbivore crop pests. Moreover, higher mean temperatures and increased frequency of climatic extremes are expected to induce different responses across trophic levels, potentially disrupting predator-prey interactions. Using field observations, we examined the response of an aph...

The purpose of this review was to examine sport officials’ motivation and passion to become and remain a referee in today’s sport climate. There are endless accounts of misconduct towards officials from participants, coaches, parents and fans. This review examined the research evidence that explained why officials continue to work in their sport and tried to determine what motivations were fact...
