Purpose: The purpose of this study is to investigate undergraduate student information self-efficacy to find out how much the students learned from library instruction classes and to determine whether information seeking skills can be developed with a library instruction class. Design/methodology/approach: A quantitative research method was conducted to collect survey data and to perform statistical analysis. A Web-based survey was distributed to undergraduate students who were enrolled in the Fall term of 2014. In all, 98 students completed the survey. Findings: The study reported that undergraduate students’ capability of information finding, retrieving, analyzing, evaluating and presenting were on and above medium level (M = 3.40). They reported higher skills in information evaluation and information objects and types but lower skills in using catalog/database and organizing/synthesizing information. Students in the multiple library instruction group showed a significantly higher information self-efficacy. One-single instruction has a limited effect on improving information seeking skills. Research limitations/implications: The number of students who participated in library instruction classes was relatively low. More data need to be collected to give credence to the findings in the future, and data collected from individual class would yield more accurate result. Originality/value: This study extends the literature on information literacy and library instruction. The findings suggest that information literacy instruction should go beyond the one-session mode and should offer hands-on practices that will foster students’ critical thinking behavior more effectively.

The Rice–Fish Symbiotic System in the Longxian village is the first Globally Important Agricultural Heritage System (GIAHS) in Asia. This paper examined the value transformation mechanism of the Longxian Rice–Fish Symbiotic System from the micro perspective of material cycle and energy flow and quantified its economic value using the gross ecosystem product (GEP). Using the InVEST model and ArcGIS tools, the GEP was estimated to be approximately CNY 116.51 million (approx. CNY 252,624 per hectare per year). The ecosystem regulating service value occupied more than 80% of the GEP. Within the regulating ecosystem services, the climate regulation value was the highest (CNY 55.72 million) followed by flood storage value (CNY 32.77 million). These two categories contributed 94.44% of the total value of regulating ecosystem services. The paper recommends employing GEP to evaluate the value of commodities and services provided by an ecosystem. The methodology and approach of the research can serve as an important reference for other GIAHS programs and provides a scientific and rigorous framework for accessing the economic value of agricultural heritage systems.
