The effects of lecturer commitment on student perceptions of teaching quality and student satisfaction in Chinese higher education

Abstract: Student satisfaction has become an important concept in higher education because students are paying higher tuition fees and increasingly seeing themselves as customers and because satisfaction is commonly used as an indicator of quality by quality assurance agencies and the compilers of rankings and league tables. In business organisations, it has been established that employee commitment has a significant impact on employee performance and customer satisfaction. The purpose of this research is to examine the effects of lecturer commitment on student perceptions of teaching quality and student satisfaction. The sample comprised 24 lecturers and 456 students at one Chinese university. Data were obtained through self-administered paper-based questionnaires. A model linking lecturer commitment with students’ perceived teaching quality and student satisfaction was created and the hypotheses were tested using structural equation modelling. It was found that lecturer commitment to students’ academic achievemen...

Fluorescent ion-imprinted sensor for selective and sensitive detection of copper (II) ions

Abstract: In the present study, a fluorescent ion-imprinted sensor (FIIS) for rapid and convenient detection of Cu2+ ions was fabricated. A fluorescent polymerizable ligand, i.e., 4-(2-aminomethyl)pyridine-N-allylnaphthalimide, was designed and synthesized. The FIIS was prepared by surface functionalization of PVDF membrane with a thin layer of copper (II) ion-imprinted polymer using the synthesized ligand as the fluorescent functional monomer. The intensity of fluorescence emission of FIIS decreased linearly with the increase of copper (II) ions concentration in the range of 0–70.0 μM. The results of selectivity tests indicated that FIIS has high specific recognition ability for Cu2+ ions. The recoveries for the spiked samples were in the range of 96.4–104.4%, and the relative standard deviations (RSDs) were found to be 2.17–4.75%. The FIIS was successfully applied to the determination of copper (II) ions in real water samples. The Limits of detection (LODs) for Cu2+ ions in real water samples were in the range of 0.11–0.14 uM. The present study provided a feasible strategy for construction of fluorescent ion-imprinted sensor for convenient, sensitive and selective detection of metal ions.
