Search for new and renewable sources of energy has made research reach the tiny little tots, microalgae for the production of biodiesel. But despite years of research on the topic, a definitive statement, declaring microalgae as an economically, environmentally, and socially sustainable resource is yet to be seen or heard of. With technological and scientific glitches being blamed for this delay in the progress of the production system, an assessment of the sustainability indices achieved so far by the microalgal biodiesel is important to be done so as to direct future research efforts in a more coordinated manner to achieve the sustainability mark. This article provides a review of the current economic, environmental, and social status of microalgal biodiesel and the strategies adopted to achieve them, with suggestions to address the challenges faced by the microalgal biodiesel production system.

We discuss the form of application of renewable sources of energy including solar energy and geothermal energy in the environment of construction, and an integrated project on renewable sources of energy is taken as a case study. We also analyze the feasible plans that utilize multiple renewable sources of energy in the construction. The significance of the energy conservation and reduction is presented as well.

Corporations are under growing pressure from socially responsible investors to consider the environmental and social impacts of their operations. To help highlight corporations that have taken steps to address these issues, a number of sustainability indices have been developed. While there is a growing body of literature that focuses on sustainability indices, little is known on how they are used in practice. The purpose of this project was to explore the use of sustainability indices in corporations. In this project, the Dow Jones Sustainability Index North America (DJSINA) was used in a case study. The project consisted of three key phases: a content analysis of corporate sustainability reports in North America, a survey with Canadian experts on the DJSINA, and a review of the DJSI website. The project highlights the similarities and differences in the use of the DJSI by Canadian and American corporations. As the first study focusing on the use of the DJSINA, the results will be of interest to practitioners and academics in socially responsible investment and corporate sustainability.

Purpose Significant transitions in firms (e.g. outsourcing) may impact the relative importance of production and inventory assets, affecting the hierarchical separation of planning decisions. The purpose of this paper is to contribute to planning literature by investigating how the production system and the planning environment influence the performance difference between hierarchical and monolithic planning. Further, it seeks to reduce the prevailing theory-practice gap in tactical planning. Design/methodology/approach Through an action research study, a monolithic model integrating tactical production planning decisions, subject to upstream supply chain constraints, with strategic investments decisions was developed, tested and implemented in a global OEM. Using the developed model and a measure of the capital cost of production assets relative to the cost of holding inventory, it is numerically examined how the production system and planning environment influence the performance of hierarchical and monolithic planning. Findings The research demonstrates the potential of integrating decisions and reveals significant performance differences between hierarchical and monolithic planning for firms with low capital cost relative to inventory holding cost. Research limitations/implications The findings suggest a fit between planning processes, the production system and planning environment. Future research should empirically validate the findings and propositions. Originality/value The paper combine capital investments and production planning decisions, which usually transpire at different hierarchical levels and on different time-horizons, and investigates the consequences of hierarchical separation through a real-life validated case and numerical analysis.

While there have been an increasing number of researches done on branding and consumer behavior especially on brand personality, social status and vanity and its influence on purchase intention, there are little researches that focus on the influence of all these factors collectively on Apps purchase intention. In addition, the fact that the influence of some factors will vary from country to country could not be ignored. This chapter conceptually argues that brand personality, social status, and physical vanity are important in building luxury fashion branded Apps. While brand personality and luxury fashion branded Apps as an internal factor plays an important role in deciphering if it has an influence on an individual's Apps purchase intention for luxury fashion brands; therefore, it is important to look into how external factors have an influence on an individual. The theoretical and future research directions are discussed.
