Two widely used scales of Internet addiction (IA), the Internet Addiction Test (IAT) and the Chen Internet Addiction Scale (CIAS), were compared and a new scale of IA was assembled from their items with improved reliability in terms of classification consistency. A total of 467 Chinese college students participated in the study. Items were calibrated using… (More)
We propose hMDAP, a hybrid framework for large-scale data analytical processing on Spark, to support multi-paradigm process (incl. OLAP, machine learning, and graph analysis etc.) in distributed environments. The framework features a three-layer data process module and a business process module which controls the former. We will demonstrate the strength of… (More)
Aging of secondary organic aerosol (SOA) particles formed from OH- initiated oxidation of ethylbenzene in the presence of high mass (100-300μg/m(3)) concentrations of (NH4)2SO4 seed aerosol was investigated in a home-made smog chamber in this study. The chemical composition of aged ethylbenzene SOA particles was measured using an aerosol laser… (More)
In this paper, we present a federated path querying language (FPQ) as itself an extension of the nested regular path querying language with adding an axis operator to support the federation of RDF dataset and relational database. We have proven that FPQ has more expressive power than the nested regular path query language (not to mention regular path… (More)
Oligoamide strands containing tertiary amide groups were found to share a basic structural motif that promotes the formation of H-bonded, chain- or tape-like supramolecular assemblies.
New 6,13-bis[1'-(C≡C)-2'-R-1',2'-C2B10H10]pentacenes (R = H, Me, Et, n-Bu) are synthesized and fully characterized. The results show that the alkyl substituents on the second cage carbon have a significant impact on the molecular packing, and the incorporation of the o-carboranyl moiety into a π conjugated system can lower both LUMO and HOMO energy levels,… (More)
