Viscous Effect on Surface Waves Generated by Steady Disturbances

A linearized theory is applied here to investigate the viscous effect on water waves generated and maintained by a system of external disturbances which is distributed over the free surface of an otherwise uniform flow. The flow is taken to be in the steady state configuration. The analysis is carried out to yield the asymptotic expressions for the surface wave when the Reynolds number of the flow is either large or small

On Being Better but not Smarter than Others: The Muhammad Ali Effect

Past research suggests that people believe that they perform socially desirable behaviors more frequently and socially undesirable behaviors less frequently than others (Goethals, 1986; Messick, Bloom, Boldizar, & Samuelson, 1985). The present research examined whether this perception also characterizes people\u27s thinking about intelligent and unintelligent behaviors. In Study 1, subjects wrote lists of behaviors that they or others did. Subjects indicated that they performed more good and intelligent behaviors and fewer bad and unintelligent behaviors than others, although the magnitude of these differences was greater for good and bad acts than for intelligent and unintelligent ones. In Study 2, a different group of subjects judged the frequency with which the behaviors generated in the first study occur. While self-ascribed good behaviors were related as occurring more frequently than the good acts of others, self-ascribed intelligent behaviors were not judged as more frequent than the intelligent acts of others. Study 3 replicated this effect using a different methodology, finding that subjects indicated they would be more likely than their peers to perform moral behaviors, but no more likely to perform intellectual behaviors. A theoretical framework is proposed in which people\u27s positive beliefs about themselves are constrained by the publicity, specificity, and objectivity of the dimensions on which these beliefs are held

Submicron gate InP power MISFET's with improved output power density at 18 and 20 GHz

The microwave characteristics are presented at 18 and 20 GHz of submicron gate indium phosphide (InP) metal-insulator-semiconductor field-effect transistors (MISFET's) for high output power density applications. InP power MISFET's were fabricated and the output power density was investigated as a function of drain-source spacing. The best output power density and gain were obtained for drain-source spacing of 3 microns. The output power density is 2.7 times greater than was previously measured for InP MISFET's at 18 and 20 GHz, and the power-added efficiency also increased

Linear Response Calculations of Lattice Dynamics in Strongly Correlated Systems

We introduce a new linear response method to study the lattice dynamics of materials with strong correlations. It is based on a combination of dynamical mean field theory of strongly correlated electrons and the local density functional theory of electronic structure of solids. We apply the method to study the phonon dispersions of a prototype Mott insulator NiO. Our results show overall much better agreement with experiment than the corresponding local density predictions.Comment: 4 pages, 2 figure

Conceptions of Leadership: Enduring Ideas and Emerging Insights

Conceptions of Leadership gathers together the latest work by distinguished leadership scholars in social psychology and related disciplines to explore classic conceptions of leadership, such as interpersonal influence, charisma, personality, and power, as well as recent perspectives on those enduring concerns. It includes contemporary departures from traditional approaches to leadership in considering gender, trust, narratives, and the complex relationships between leaders and followers. Together the chapters provide a wide-ranging and coherent account of how human beings get along and the ways they engage and work together to accomplish their goals.https://scholarship.richmond.edu/bookshelf/1198/thumbnail.jp

the impact of delayed treatment on 6 minute walk distance test in patients with pulmonary arterial hypertension a meta analysis

Abstract Background The impact of treatment delay in stable patients with pulmonary arterial hypertension (PAH) remains unaddressed. Methods This meta-analysis included six datasets of PAH therapies with randomized-controlled trials (RCT) and corresponding open-label extension (OLE) studies. We evaluated the change in 6MWD at 1year in the OLE studies by active treatment versus ex-placebo group. The ex-placebo group (i.e., the patients randomized to placebo in the RCT and ultimately treated with active therapy in the OLE) represented the "delay-in-treatment" population. Results Patients with a treatment delay of 12–16weeks in PAH targeted therapy had an improvement in 6-minute walk distance (6MWD) test at 1year, but this improvement did not amount to the same degree of improvement as their initially treated counterparts. The difference in 6MWD was 15m to 20m at 1year. Conclusion A short-term delay in PAH targeted therapy may adversely affect functional capacity in patients with PAH. This meta-analysis provides some insight as to whether earlier treatment would benefit stable patients with PAH

Apparent quality-of-life in nations : how long and happy people live

Quality-of-life in nations can be measured by how long and happy people live. This is assessed by combining data on life expectancy drawn from civil registration with survey data on subjective enjoyment of life as a whole. This measure of 'apparent' quality-of-life is a good alternative to current indexes of 'assumed' quality-of-life such as the Human Development Index. Data are available for 67 nations in the 1990s. The number of Happy-Life-Years varies considerably across nations. Switzerland is at the top with 63.0 years and Moldavia at the bottom with 20.5 years. China is in the middle with an average of 46.7. Happy lifetime has risen considerably in advanced nations over the last decade. People live longer and happier in nations characterised by economic affluence, freedom and justice. Together these three societal qualities explain 66% of the cross-national variance in Happy-Life-Years. Income equality and generous social security do not appear to be required for a long and happy life

Researcher Degrees of Freedom in the Psychology of Religion

There is a push in psychology toward more transparent practices, stemming partially as a response to the replication crisis. We argue that the psychology of religion should help lead the way toward these new, more transparent practices to ensure a robust and dynamic subfield. One of the major issues that proponents of Open Science practices hope to address is researcher degrees of freedom (RDF). We pre-registered and conducted a systematic review of the 2017 issues from three psychology of religion journals. We aimed to identify the extent to which the psychology of religion has embraced Open Science practices and the role of RDF within the subfield. We found that many of the methodologies that help to increase transparency, such as pre-registration, have yet to be adopted by those in the subfield. In light of these findings, we present recommendations for addressing the issue of transparency in the psychology of religion and outline how to move toward these new Open Science practices
