Large-scale uncitedness refers to the remarkable proportion of articles that do not receive a single citation within five years of publication. Equally remarkable is the brief and troubled history of this area of inquiry, which was prone to miscalculation, misinterpretation, and politicization. This article reassesses large-scale uncitedness as both a general phenomenon in the scholarly communication system and a case study of library and information science, where its rate is 72 percent.

Despite much discussion concerning problems with, and potential changes to, the psychological publishing system, there has been little data gathered concerning psychologists’opinions about whether, or what, change needs to occur. Here we surveyed psychologists about: the literature in their subfield, the current publication system,the prevalence of problems in review, how helpful potential changes to the communication system might be, and their behavioral engagement in current change initiatives. While over half of psychologists agreed to being generally satisfied, most also agreed there is room to improve the communication system and indicated that several potential changes would be helpful. Unfortunately, the majority of psychologists also indicated not yet engaging behaviorally with current change initiatives. Sensible problem and change components were drawn from the data and were correlated to, for instance, how much trust the psychologist had in the literature of their subfield and how many papers they had published.

This paper investigates the problem of maximizing the secrecy energy efficiency (SEE) for unmanned aerial vehicle- (UAV-) to-ground wireless communication system, in which a fixed-wing UAV tries to transmit covert information to a terrestrial legitimate destination receiver with multiple terrestrial eavesdroppers. In particular, we intend to maximize the worst-case SEE of UAV by jointly optimizing UAV’s flight trajectory and transmit power over a finite flight period. However, the formulated problem is challenging to solve because of its large-scale nonconvexity. For efficiently solving this problem, we first decouple the above optimization problem into two subproblems and then propose an alternating iterative algorithm by adopting block coordinate descent method and Dinkelbach’s algorithm as well as successive convex approximation technique to seek a suboptimal solution. For the sake of performance comparison, two benchmark schemes, the secrecy rate maximization (SRM) scheme and constrained energy minimization (CEM) scheme are considered to obtain more useful insights. Finally, simulation results are executed to verify that our proposed SEE maximization (SEEM) algorithm is superior to two benchmark schemes for the UAV-ground communication system.

In this essay, I mainly discuss the self-organizing property of the Internet communication system. As an important part of the human information communication system, Internet communication has progressively become a system with large scale, complex constructions, and perfect functions through the complicated interactions among many sub-systems and their elements. In this process, which is mainly promoted by Internet users, the self-growth of the Internet communica- tion system not only increases the amount of its sub-systems and its elements, it also strengthens its constructions and functions. At the same time, the self-growth of the Internet communication system indicates that the system is an evolving system with self-organizing property.
