The first section describes psychophysiological systems and theories that can inform organizational scholars' understanding of the biological bases of behavior in organizations. The second section discusses the advantages and challenges associated with incorporating psychophysiological measures into organizational research. The third section speculates on some possible domains where the use of psychophysiological measures may provide novel insights into key organizational phenomena. In sum, this chapter provides an opportunity for organizational scholars to think about how incorporating physiological measures and outcomes into organizational research can deepen theoretical insights and enrich our understanding of human behavior in organizations.

Which type of product or service is best suitable for these stars to advertise? What can we expect from these ads? Who is the ideal sports star? Is it true that social media is going to transform this area as well? For our research we examined print ads and television commercials using famous athletes such as

Images typical of NCLVM and CCHD were documented by cardiac magnetic resonance imaging (CMRI).

After introducing the problem and providing context in the first section, we discuss recent work related to image generation in Section 2. In Section 3, we describe the methods used to fine-tune our CNN and generate new images using a novel approach inspired by a Gaussian mixture model. In Section 4, we discuss our working dataset and describe our preprocessing steps and handling of facial attributes. Finally, in Sections 5, 6 and 7, we explain our experiments and results and conclude in the following section. Our classification system has 82\% test accuracy. Furthermore, our generation pipeline successfully creates well-formed faces.
