The new workplace is a key arena for learning in today’s society. The spiraling demand for knowledge in the workplace has increased interest in learning, especially team learning. Team learning can be viewed from multiple perspectives, making it difficult for career and technical educators (CTEs) to know how to prepare students for a team-based work environment, especially one that includes vir...

The waterchestnut (Trapa natans var. japonica Nakai) has been dominating the entire in Lake North Inbanuma, Chiba Prefecture, Japan. In order to investigate the seasonal variation of its surface coverage area, photographic recording of surface areas occupied by waterchestnuts in ten quadrats carried out from a boat every two weeks over a period of two years. In addition, the waterchestnuts were...

We use the conditional distribution and conditional expectation of one random variable given the other one being large to capture the strength of dependence in the tails of a bivariate random vector. We study the tail behavior of the boundary conditional cumulative distribution function (cdf) and two forms of conditional tail expectation (CTE) for various bivariate copula families. In general, ...

Results from portfolio models for credit risk tell us that loan concentration in certain industry sectors can substantially increase the value-at-risk (V aR). The purpose of this paper is to analyse if a very tractable “infection model” can provide a meaningful estimate of the impact of concentration risk on the V aR. This would be achieved with quite parsimonious data requirements, which are c...

The subalpine zones on the mountains south of the Tohoku mountains in the Japanese Islands are normally occupied by coniferous forests dominated by Abies mariesii, A. veitchii, Picea jezoensis var. hondoensis and Tsuga diversifolia. But there are many mountains where the subalpine coniferous forest does not exist; the thermometrical subalpine zones on such mountains are replaced by subalpine an...
