Institutional environment, managerial attitudes and environmental sustainability orientation of small firms

This study examines the direct impact of three dimensions of the institutional environment on managerial attitudes toward the natural environment and the direct influence of the latter on the environmental sustainability orientation (ESO) of small firms. We contend that when the institutional environment is perceived by owner–managers as supportive of sound natural environment management practices, they are more likely to develop a positive attitude toward natural environment issues and concerns. Such owner–manager attitudes are likely to lead to a positive and proactive orientation of their firms toward environmental sustainability. The study uses survey data from 166 small manufacturing firms located in three Philippine cities. First, the study develops and tests the measurement models to examine the validity of the constructs representing the firm’s institutional environment, managerial attitudes toward the natural environment and the ESO of firms. Second, the study develops and tests the structural models examining the institutional environment–managerial attitudes–ESO linkages. Multi-sample invariance structural model analysis shows the mediating role of managerial attitudes in the institutional environment–ESO nexus. The findings show that ESO is a construct comprising three dimensions: knowledge of environmental issues, sustainable practices and commitment toward environmental sustainability. The cognitive, regulatory and normative elements of the institutional environment are strongly linked to positive managerial attitudes toward environmental sustainability, which in turn, positively influences the firm’s overall ESO. Managerial attitudes play a mediating role in the institutional environment–ESO linkages. The managerial, practical, research and policy implications of the research findings are discussed.

Self-assembled V2O5 interconnected microspheres produced in a fish-water electrolyte medium as a high-performance lithium-ion-battery cathode

Interconnected microspheres of V2O5 composed of ultra-long nanobelts are synthesized in an environmental friendly way by adopting a conventional anodization process combined with annealing. The synthesis process is simple and low-cost because it does not require any additional chemicals or reagents. Commercial fish-water is used as an electrolyte medium to anodize vanadium foil for the first time. Electron microscopy investigation reveals that each belt consists of numerous nanofibers with free space between them. Therefore, this novel nanostructure demonstrates many outstanding features during electrochemical operation. This structure prevents self-aggregation of active materials and fully utilizes the advantage of active materials by maintaining a large effective contact area between active materials, conductive additives, and electrolyte, which is a key challenge for most nanomaterials. The electrodes exhibit promising electrochemical performance with a stable discharge capacity of 227 mAh·g–1 at 1C after 200 cycles. The rate capability of the electrode is outstanding, and the obtained capacity is as high as 278 at 0.5C, 259 at 1C, 240 at 2C, 206 at 5C, and 166 mAh·g–1 at 10C. Overall, this novel structure could be one of the most favorable nanostructures of vanadium oxide-based cathodes for Li-ion batteries. [Figure not available: see fulltext.]
