Many students are troubled with percentage. The difficulty may lie in the way in which it is presented. Survey tests in Kern County and elsewhere have inclicated a lack of achievement in this particular field. Many teachers have indicated their awareness of the problem in teaching clear concepts in the field of percentage. Supervisors and consultants have observed that many teachers and pupils have difficulties in this field. In order to study the problem at some length and determine if possible, remedial measures, the following study was undertaken.

AbstractMoiré lattices formed in twisted van der Waals bilayers provide a unique, tunable platform to realize coupled electron or exciton lattices unavailable before. While twist angle between the bilayer has been shown to be a critical parameter in engineering the moiré potential and enabling novel phenomena in electronic moiré systems, a systematic experimental study as a function of twist angle is still missing. Here we show that not only are moiré excitons robust in bilayers of even large twist angles, but also properties of the moiré excitons are dependant on, and controllable by, the moiré reciprocal lattice period via twist-angle tuning. From the twist-angle dependence, we furthermore obtain the effective mass of the interlayer excitons and the electron inter-layer tunneling strength, which are difficult to measure experimentally otherwise. These findings pave the way for understanding and engineering rich moiré-lattice induced phenomena in angle-twisted semiconductor van der Waals heterostructures.

The purpose of the following pages is to study the problem of debt in Rome of the Ciceronian age. A part of this argument will be uncontroversial or at least familiar; that is, the way in which Roman politicians lived in prolonged states of indebtedness. The rest of the argument will be frankly more speculative; it will suggest that Caesar's arrival in Rome in 49 B.C. provoked a crisis that was in some degree inevitable; but that Caesar in consequence undertook certain remedial measures that were of an importance for the future developments of Roman law.

The authors put forward a new design of experimental setup in order to study the mechanism of magnetic fluid seal, and used Ansys to simulate the magnetic field distribution in the setup, the results prove its rationality. The experiment to study the way of pressure transmission has been done on the experimental setup. The experimental conclusion shows that pressure transmission is based on the recoverability of the magnetic fluid seal. When pressure exceeds the ability of the seal stage, there is a leak path in the magnetic fluid, and then the gas flows to the next stage, after that, the leak path disappears. Pressure transmits from one seal stage to the next one in this way.

This paper presents a game theoretic view of collaborative work and suggests that the design of effective GDSS tools should be guided by the way the tool discourages dysfunctional gaming behavior. We present an illustrative experimental study that investigates the influence of communication channel, incentive structure, and problem modeling tools on decision performance, diversity of solutions, and information exchange truthfulness in collaborating groups.

Abstract Objectives This study tested whether the presence of a firearm changed the way people reacted to police among a British sample. Method In an online study, participants were shown images of armed and unarmed police and rated them on a number of variables. Some participants were primed to think about terrorism, and some participants were exposed to more armed police than others. Results Participants had more negative responses to police when they were armed. We found no effect of the terrorism prime on people’s reactions to images of armed police and no effect of exposure. Yet, unexpectedly, we found a negative effect of the terrorism prime on trust and legitimacy. Conclusions In a country where police have never before been routinely armed, this research raises important questions about how armed police can retain the public’s support when they may no longer be considered ‘prototypical representatives’ of the British people.

The Way

Competitiveness is outside modernity in all sectors of society. The execution of tasks has become too complex due to the problems brought by the integration of globalization as a synonym for competition. Undoubtedly, the way to respond to the complexity of the current environment is through the integration of work teams that can be efficient; And the only way to guarantee success is by supplementing the few personality traits developed with the well-worked skills of other team members. Therefore, this research developed a quasi-experimental study in 62 people; to demonstrate that work teams formed by eneatypes or personality traits, obtained by the enneagram map test, are more efficient than traditional equipment. The main contributions to the knowledge gap of this research are: demystification of the enneagram; demonstrating through a quantitative study that the participants obtain better results when working in teams formed with enneagram; participants have a positive perception about enneagram; and using the tools of neuroscience it is proved with physiological data that the theoretical precepts of enneagram are correct.
