Fourth Wave

Fourth wave of industrial revolution is marked by the use of information technology, artificial inteligence (A.I), and automatic engines. Competitive advantage has become a necessity for every business actor when they wants to competing in the global market. The current condition definitely encouraging the occurence of massive transformation at all business levels and units this condition happens because every business actor can enter from and any other countries markets easily. this condition making professionalism of every business actor is highly prioritized like many case in the business decision making and continous innovation.

Over Time

In the San Francisco Bay Area, during the last nine years advocates have made major inroads in shifting local policies and approaches to urban agriculture. At the same time, the city’s landscape has undergone massive transformation. In this chapter, based on personal experiences as leaders in urban agriculture in the Bay Area and as researchers on the (transformational) politics of food systems, we propose that the justice-driven components of urban agriculture movements are subject to the influence of broader changes in political-economic context, and that urban agriculture is easily absorbed into existing neoliberal and pro-development political trajectories and projects. In this chapter, through the case of the San Francisco Urban Agriculture Alliance, we analyze the movement’s composition, its genesis over time, and how the movement has confronted the tensions and limitations of neoliberal urbanization.

Different Levels

The widespread implementation and adoption of digital technologies by organizations has given rise to a massive transformation with the potential to affect many organizations’ internal operations and processes. This transformation affects different levels and steps of output creation in companies, which eventually triggers changes in their organizational structures. This article develops an integrated picture on how digital transformation affects organization design by classifying and analyzing the effect on the process of output creation in firms. Based on this picture, it develops and elaborates on potential opportunities and challenges for companies resulting from digital transformation. Finally, it offers recommendations and decisions rules for dealing with these issues.

Nucleation Mechanisms

Rapid cooling of TiAl-based alloy from α phase (disordered hexagonal, A3) generates  phase (ordered tetragonal, L1o) grains through massive transformation nucleating mostly over the α/α grain boundaries. This current work deals with the identification and the validation of different nucleation mechanisms during  massive transformation in TiAl-based alloys. Special attention has been given to the variant selection criteria for the nucleation of the massive structures along different types of α/α grain boundaries. The  massive domains formed along the grain boundaries were analysed using high resolution electron backscattered diffraction (EBSD). Statistical studies were made on different nucleation sites and different mechanisms are proposed. Two–dimensional studies of the nucleation mechanism suggest that the minimization of the interfacial energy could be the predominant criteria during the grain boundary nucleation. In order to verify this nucleation criterion in three-dimensions, serial sections were made and EBSD maps were taken and analysed in each section. The variant selection observed during the nucleation and the growth of the  massive grains is further discussed after getting a broader view under three-dimensional investigations.
