<p> Despite the relevance of properly setting ionic concentrations in Molecular Dynamics (MD) simulations, methods or practical rules to set ionic strength are scarce and rarely documented. Based on a recently proposed thermodynamics method we provide an accurate rule of thumb to define the electrolytic content in simulation boxes. Extending the use of good practices in setting up MD systems is promptly needed to ensure reproducibility and consistency in molecular simulations.</p>

We investigated whether adding product information in mobile commerce improved consumers’ attitudes toward a product and whether this relationship was moderated by consumption goals. We conducted two field experiments in which we recruited parents in Korea and the USA and asked them how they evaluated two childcare hybrid products (HPs) newly developed by Samsung Electronics designers. The results revealed that participants exposed to additional information about the HPs evaluated them more favorably than those who were not exposed. However, this relationship disappeared when a consumption goal was activated. Our findings establish a dynamic relationship between information seeking and consumption goals, asking designers to rethink their rule of thumb in the mobile commerce context.

Many universities admit students to degree courses in mechanical engineering from a wide variety of backgrounds. The majority enter with a study of A level mathematics. An increasing proportion enter having previously studied for BTEC qualifications. The conventional rule of thumb which is used is that BTEC level 3 is equivalent to A level. In this paper this rule of thumb is examined by comparing the performance of A level and BTEC students in a diagnostic test, taken at the start of their course, and the results of the end-of-year examination. The results of students entering the mechanical engineering stream of degree courses at Coventry University in 1991 and 1992 are used to provide the data for this study. The diagnostic test results also show the key areas of weakness in the level of mathematical competence of many students on entry to universities.

Progressives who opposed the Trump administration’s policies found themselves repeatedly relying on constitutional principles grounded in federalism, separation of powers, and free speech to resist the federal government. Although many progressives had either criticized or underemphasized those principles before Trump, the principles became vital to progressive causes after Trump was elected. Using dozens of examples from the ways in which Trump abused presidential powers, this book explains how the three sets of principles can help mitigate the harms that autocratic leaders in the Trump mold can inflict on both democratic institutions and vulnerable minorities. In doing so, the book urges progressives to follow this rule of thumb in the post-Trump era: if a constitutional principle was worth deploying to resist Trump’s harmful policies and autocratic governance, then it is likely worth defending in the post-Trump era even if it makes the short-term attainment of progressive objectives more difficult. This type of principled constitutionalism is essential not only because being principled is good in and of itself, but also because being principled in matters related to federalism, separation of powers, and free speech will help both advance progressive causes over the long run and reduce the threats posed by future autocratic leaders in the Trump mold to our system of self-governance, to our democratic values, and to traditionally subordinated minorities. Going forward, progressives should promote and defend constitutional principles grounded in federalism, separation of powers, and free speech regardless of whether they have an ally or an opponent in the White House.
