The foremost feature in modern science and technology is the expanding role of mathematics. In industry and business the increasing complexity of problems and the ever-present search for better products and services, lead to the use of mathematical methods. Trial and error methods can not alone yield the information of the behavior of a physical system or a business procedure or an economic process necessary if improvement in design or function is to be achieved. To understand and evaluate the effects of small components on the behavior of a system, it must be considered as a single operating unit. The functional dependance of the entire system must be expressed in terms of all of the components, large and small. Thus a mathematical model emerges which is an abstraction of the quantitative and logical relationships of the system. Often, as further improvements are sought, the effect of a larger number of these smaller components need to be understood and weighed. It is thus the proper evaluation of the small effects or “second order effects” that determines progress.

The coronavirus disease 2019 (COVID-19) is a global crisis spreading to all countries. This study explains and documents the first-order effects of the new coronavirus on the urban water cycle. Urban water systems play an important role in public health because people rely so heavily on water services. Findings address short- and long-term changes in climate variables; availability and accessibility of clean water to prevent and control the spread of coronavirus in water-scarce cities; shifts in habits, behavior, and lifestyles of people and effects on water demand during lockdowns; and role of wastewater treatment in preventing the spread of coronavirus.

A moderated process model is presented that attempts to explain the consistency between implicit and explicit indicators as a function of awareness, i.e. the degree to which persons become aware of their implicit attitude, and adjustment, i.e. the degree to which they adjust for the explicit response. In two experiments on attitudes of West Germans toward East Germans and Turks, a number of dispositional moderators pertaining to awareness and adjustment were tested. Concerning moderators affecting awareness, no reliable first‐order effects were found for Private Self‐Consciousness or Attitudinal Self‐Knowledge. However, Attitude Importance generated the expected effect. Concerning moderators influencing adjustment, consistent effects were obtained for Motivation to Control Prejudiced Reactions. Social Desirability and Self‐Monitoring did not moderate the implicit–explicit relationship in the expected direction. Some evidence was found for a second‐order moderator effect between awareness and adjustment, suggesting that adjustment effects may be more pronounced under conditions of high awareness.

The interaction of a modulated electron beam and a narrow tape helix is considered using a confined flow model for the beam. With this model, the analysis is self-consistent in that it takes into account the first-order effects of the interaction on the beam. The interaction is studied by means of complex waves on the composite system of the beam and the helix. The role of these waves is established in part on the basis of their complex wave numbers which are solutions of the appropriate determinantal equation. Although coupling similar to that used in traveling wave tubes is considered initially, the investigation concentrates on coupling which can be used to produce Smith–Purcell radiation. The results of the numerical evaluation of the wave numbers demonstrate that for the latter type of coupling, the modulation changes very slowly along the length of the interaction. This establishes the heretofore questionable validity of the prescribed source model for evaluating the interaction of a modulated electron beam and a narrow tape helix. Similar results are expected to hold for other interaction geometries.
