Phenotypic decision-making is a process of determining important phenotypes in accordance with the available microenvironmental information. Although phenotypic decision at the level of a single cell has been precisely studied, but the knowledge is still imperceptible at the multicellular level. How cells sense their environment and adapt? How single cells change their phenotype in a multicellular complex environment (without knowing the interactions among the cells), is still a rheotorical question. To unravel the fragmental story of multicellular decision-making, Least microEnvironmental Uncertainty Principle (LEUP) was refined and applied in this context. To address this set of questions, we use variational principle to grasp the role of sensitivity, build a LEUP driven agent-based model on a lattice which solely hinges on microenvironmental information and investigate the parallels in a well-known biological system, viz., Notch-Delta-Jagged signaling pathway. The analyses of this model led us to interesting spatiotemporal patterns in a population of cells, responsive to the sensitivity parameter and the radius of interaction. This resembles the tissue-level pattern of a population of cells interacting via Notch-Delta-Jagged signaling pathway in some parameter regimes.

And Gender

Increasingly, organizations are oriented towards groups to make decisions. This is because some contextual factors have undergone significant changes. Companies are operating in a competitive, dynamic and complex environment, having to face with unstructured and non-programmed decisions. Organizations are also oriented towards participatory processes in order to benefit from the important advantages that these processes offer. The main goal of the current research is to understand if there is a correlation between group decision-making propensity, age and gender. The motivation for the current research starts from the consideration that the degree of preference for group decision-making processes determines the contribution and commitment of the members, with important consequences on the decisions’ effectiveness. The processing and analysis of the collected data indicate that adults prefer group decision-making processes more than young people and women prefer group decision-making processes less than men.

In order to improve capability of operational decision-making synchronization (ODMS) in command and control (C2) organization, the paper puts forward that ODMS is the negotiation process of situation cognition with three phases about “situation cognition, situation interaction and decision-making synchronization” in complex environment, and then the model and strategies of ODMS are given in quantity. Firstly, measure indexes of three steps above are given in the paper based on the time consumed in negotiation, and three patterns are proposed for negotiating timely in high quality during situation interaction. Secondly, the ODMS model with two stages in continuous changing situation is put forward in the paper, and ODMS strategies are analyzed within environment influence and time restriction. Thirdly, simulation cases are given to validate the process of ODMS under different continuous changing situations the results of this model are better than the other previous models to fulfill the actual restrictions, and the process of ODMS can be adjusted more reasonable for improving the capability of ODMS. Then we discuss the case and summarize the influence factors of ODMS in the C2 organization as organization structure, shared information resources, negotiation patterns, and allocation of decision rights.

As If

The need for including decision making training objectives in the development of flight crew training programs is evident given the dynamic and complex environment in which the pilots perform. The experience of one airline in developing training for their flight crews has demonstrated that these types of objectives can be effectively integrated into their line oriented flight training (LOFT) program. The primary goal of LOFT is to create a realistic environment in which the pilots perform as if they are in line operations. Performance in this environment sets the stage for an effective training debriefing. An essential part of creating this environment is allowing for realistic decisions to be made that are followed by the appropriate outcomes and consequences. Pilots have consistently rated these training events as effective and helpful. Besides these student critiques, the effectiveness of the training is also evaluated using check pilot observations of crew performance in line operations.

Organizational Activities

In modern organizations, information, and particularly knowledge, is known to be the most strategically important resource. The defining characteristics of modern organizational forms are purported to be flatter hierarchies, decentralized decision making, greater capacity for tolerance of ambiguity, permeable boundaries, capacity for renewal, self-organizing units, continual change, and an increasingly complex environment (Daft & Lewin, 1993; Warne, Ali, Bopping, Hart, & Pascoe, 2004). Yet, many systems that are developed to support organizational activities continue to fail at an alarming rate (Hart & Warne, 2005; Warne, 2002). Many explanations have been offered for such failures (e.g., DeLone & McLean, 1992; Fortune & Peters, 2005; Lyytinen & Hirschheim, 1987; Sauer, 1993; Warne, 2002), but contradictions and stresses continue to confound organizations and their use of information and communications technology (ICT). The challenge for information systems (IS) research and practice is to articulate an organizational paradigm, including its structures, forms, and systems, that will enable the organization to be agile, innovative, and have the capacity to learn. This article discusses some of the parameters for a new contemporary model for organizations.

Suboptimal Policies

Because overarching policy goals are distant and open to interpretation, policy makers yield to cognitive bias by constructing policies around visible elements (salient referents). US wartime policy makers thus defined US goals in Vietnam, Iraq, and Afghanistan first to serve proximate goals; then to serve disjoined tasks; eventually to serve available US (political, economic, and military) resources; and finally to serve a fixed-exit schedule, at which point leaving became the primary objective. In consequence, they exaggerated the benefits of preferred policies, ignored their accompanying costs and requirements, and underappreciated the benefits of available alternatives. These non-rational tendencies, though pervasive in decision-making, become disabling problems in the complex environment of asymmetric conflicts. With their many interdependent parts, these demanding environments confound planning and tax resources. The result was shortsighted, suboptimal policies that failed to live up to ever-diminishing expectations.

The Ideal

An appropriate project delivery system plays an essential role in sustainable construction project management. Due to the complexity of practical problems and the ambiguity of human thinking, selecting an appropriate project delivery system (PDS) is an enormous challenge for owners. This paper aims to develop a PDS selection method to deal with the related-indicators case by combining the advantages of Pythagorean fuzzy sets (PFSs) and Pythagorean fuzzy weighted Muirhead mean (PFWMM) operators. The contributions of this paper are as follows: (1) This study innovatively introduced the PFWMM operator to deal with PDS selection problems for the case of the relevance among all indicators affecting PDSs selection in a complex environment. (2) A new method of solving indicators’ weights was proposed to adapt to the related-indicators PDS selection problem, through investigating the differences between the ideal PDS and the alternative PDS under all indicators. (3) A decision-making framework for PDS selection was constructed by comprehensive use of the advantages of PFSs and the PFWMM operator in dealing with related-indicators PDS decision-making problems. An example of selecting a PDS is exhibited to illustrate the effectiveness and applicability of the proposed method.
