A validation study of the construct "jealousy" in eleven- to fourteen-month-old infants: Evidence for its divergence from "fear" and "anger"

There has been increasing interest in expanding the scope of the study of the "basic" emotions and their development in infancy to include more of the so-called "complex" emotions like jealousy. This dissertation investigated evidence for the divergence of jealousy in infants from both fear and anger, two of the basic emotions said to be precursors and contributors to the emergence of jealousy in the later part of the first year of life. Participants judged how well eight emotion-denoting terms (including jealousy, anger and fear) described infants' emotionality in fear-, anger-, and jealousy-provoking situations in which the social context of the emotion episodes was either included or excluded. Differences within and between participants' judgments of the eight terms in the two context conditions were examined across the three emotion-provoking conditions. Results suggested that infants' emotional behavior denoting jealousy was not judged differently from behavior denoting anger or fear in the absence of contextual information and, that when contextual information was provided, attributions of infant jealousy, anger, and fear were made "correctly" for their respective target emotion conditions. ^

Integrated Performance Assessment of Engineering Projects at the Interface of Emergent Properties and Uncertainty

Investigation of the performance of engineering project organizations is critical for understanding and eliminating inefficiencies in today’s dynamic global markets. The existing theoretical frameworks consider project organizations as monolithic systems and attribute the performance of project organizations to the characteristics of the constituents. However, project organizations consist of complex interdependent networks of agents, information, and resources whose interactions give rise to emergent properties that affect the overall performance of project organizations. Yet, our understanding of the emergent properties in project organizations and their impact on project performance is rather limited. This limitation is one of the major barriers towards creation of integrated theories of performance assessment in project organizations. The objective of this paper is to investigate the emergent properties that affect the ability of project organization to cope with uncertainty. Based on the theories of complex systems, we propose and test a novel framework in which the likelihood of performance variations in project organizations could be investigated based on the environment of uncertainty (i.e., static complexity, dynamic complexity, and external source of disruption) as well as the emergent properties (i.e., absorptive capacity, adaptive capacity, and restorative capacity) of project organizations. The existence and significance of different dimensions of the environment of uncertainty and emergent properties in the proposed framework are tested based on the analysis of the information collected from interviews with senior project managers in the construction industry. The outcomes of this study provide a novel theoretical lens for proactive bottom-up investigation of performance in project organizations at the interface of emergent properties and uncertainty
