Abstract  

A bibliometric analysis was performed on a set of 1718 documents relating to Web 2.0 to explore the dimensions and characteristics of this emerging field. It has been found that Web 2.0 has its root deep in social networks with medicine and sociology as the major contributing disciplines to the scholarly publications beyond its technology backbone — information and computer science. Terms germane to Web 2.0, extracted from the data collected in this study, were also visualized to reflect the very nature of this rising star on the Internet. Web 2.0, according to the current research, is of the user, by the user, and more importantly, for the user.

Co-governance Based on Abilities and Relations

An Explanation of Governance Structure of Farmer Cooperatives in Zhejiang Province, China

Authors: Zu-hui Huang, Xu-chu Xu, Yu Song and Yu Song

The institutional arrangement of farmer cooperatives in the coastal areas of east China is characterized by a distinct shareholding from the very beginning. After describing some basic facts of institutional arrangement of farmer cooperatives in Zhejiang, the paper puts forward a framework from perspectives such as institutions, norms, trust and commitment for studying the residual control rights of cooperatives. The authors not only point out that the governance structures of farmer cooperatives in the coastal areas of China are the co-governance structure based on the abilities and relations, but also analyze the unique roles of abilities and relations in constructing the governance structure of farmer cooperative in China.

Abstract  

The low-temperature molar heat capacities of CoPc and CoTMPP were measured by temperature modulated differential scanning calorimetry (TMDSC) over the temperature range from 223 to 413 K for the first time. No phase transition or thermal anomaly was observed in the experimental temperature range for CoPc. However, a structural change was found to be nonreversible for CoTMPP in the temperature range of 368–403 K, which was further validated by the results of IR and XRD. The molar enthalpy ΔH m and entropy ΔS m of phase transition of the CoTMPP were determined to be 3.301 kJ mol−1 and 8.596 J K−1 mol−1, respectively. The thermodynamic parameters of CoPc and CoTMPP such as entropy and enthalpy relative to reference temperature 298.15 K were derived based on the above molar heat capacity data. Moreover, the thermal stability of these two compounds was further investigated through TG measurements. Three steps of mass loss were observed in the TG curve for CoPc and five steps for CoTMPP.
