The challenges in Recommender System (RS) mainly involve cold start and sparsity problems. The essence behind these problems is that the extant techniques normally mainly rely on the user-item rating matrix, which sometimes is not informative enough for predicting recommendations. To solve these challenges, many existing papers considered user/item attributes as complementary information with a...

This paper incorporates a rich set of physical water quality attributes, as well as site and household characteristics, into a model of recreational lake usage in Iowa. Our analysis shows individuals are responsive to physical water quality measures. Willingness-to-pay estimates are reported based on improvements in these measures.

In today's healthcare system, there is an imbalance between what patients expect of caregivers' care and their perception of the care they get. How is it possible to reduce this imbalance? The aim of this paper was to describe attributes associated with meaningful encounters in the Swedish healthcare system based on patients' and caregivers' written narratives and to note the differences and si...

In order to evaluate the tuber fresh weight and some physiological attributes of Agria potato cultivar in response to water deficit stress and mycorrhiza inoculation, a field trial was conducted as a split plot scheme based on randomized complete block design with three replications at the research site of Islamic Azad University, Tabriz Branch in 2012. Four water levels including: irrigation a...

This study evaluated the feasibility of producing stable protein colloidal dispersion by blending dairy and pea proteins using ultra shear technology (UST). The influence different UST process parameters (shear, temperature, pressure, interactions) on quality attributes milk suspensions proportions viz., milk:pea 1:0.5, 1:1, 1:3 ratios was evaluated. treatment performed at 400 MPa pressure temp...

TOSCANA is a computer program which allows an online interaction with data bases to analyse and explore data conceptually. Such interaction uses conceptual data systems which are based on formal contexts consisting of relationships between objects and attributes. Those formal contexts often have attributes taken from a thesaurus, which may be understood as ordered set and be completed to a join...
