The origin of compression influences geometric instabilities in bilayers

Geometric instabilities in bilayered structures control the surface morphology in a wide range of biological and technical systems. Depending on the application, different mechanisms induce compressive stresses in the bilayer. However, the impact of the chosen origin of compression on the critical conditions, post-buckling evolution and higher-order pattern selection remains insufficiently understood. Here, we conduct a numerical study on a finite-element set-up and systematically vary well-known factors contributing to pattern selection under the four main origins of compression: film growth, substrate shrinkage and whole-domain compression with and without pre-stretch. We find that the origin of compression determines the substrate stretch state at the primary instability point and thus significantly affects the critical buckling conditions. Similarly, it leads to different post-buckling evolutions and secondary instability patterns when the load further increases. Our results emphasize that future phase diagrams of geometric instabilities should incorporate not only the film thickness but also the origin of compression. Thoroughly understanding the influence of the origin of compression on geometric instabilities is crucial to solving real-life problems such as the engineering of smart surfaces or the diagnosis of neuronal disorders, which typically involve temporally or spatially combined origins of compression

Noticing the self: Implicit assessment of self-focused attention using word recognition latencies

Self-focused attention is difficult to measure. Two studies developed an implicit measure of self-focus based on word recognition latencies. Self-focused attention activates self-content, so self-focused people should recognize self-relevant words more quickly. Study 1 measured individual-differences in self-focused attention. People scoring high in private self-consciousness recognized self-relevant words more quickly. Study 2 manipulated objective self-awareness with a writing task. People who wrote about distinctive self-aspects (high self-awareness) recognized self-relevant words more quickly compared to people who wrote about a neutral topic (low self-awareness) and people who did no writing (control). The discussion considers implications for future research on self-focused attention

On the dependability and feasibility of layperson ratings of divergent thinking

A new system for subjective rating of responses to divergent thinking tasks was tested using raters recruited from Amazon Mechanical Turk. The rationale for the study was to determine if such raters could provide reliable (aka generalizable) ratings from the perspective of generalizability theory. To promote reliability across the Alternative Uses and Consequence task prompts often used by researchers as measures of Divergent Thinking, two parallel scales were developed to facilitate feasibility and validity of ratings performed by laypeople. Generalizability and dependability studies were conducted separately for two scoring systems: the average-rating system and the snapshot system. Results showed that it is difficult to achieve adequate reliability using the snapshot system, while good reliability can be achieved on both task families using the average-rating system and a specific number of items and raters. Additionally, the construct validity of the average-rating system is generally good, with less validity for certain Consequences items. Recommendations for researchers wishing to adopt the new scales are discussed, along with broader issues of generalizability of subjective creativity ratings. © 2018 Hass, Rivera and Silvia

Governance Reform in Legal Service Markets

This paper discusses proposed governance reforms of legal services markets. The model distinguishes between a status quo position supported by a system of professionally enforced collective reputation and forms of governance based more squarely on market mechanisms. We identify a number of forces which determine the success of reform. Focussing particularly on the rent recapture and relationship substitution effects, we highlight their impact on client welfare and quality of legal services in different types of market according to whether clients are transient or repeated users of the service.incomplete contracts, repeated interactions

The Costs and Benefits of "Strangers": Why Mixed Communities Are Better

Much of the literature on diversity assumes that individuals have an exogenous "taste for discrimination". In contrast with this approach, we build a model where preferences over the nature of one's community are derived indirectly, and arise because the composition of the community determines the behavior of its members. This allows us to gain a far deeper understanding of the forces that underpin the desirability of diversity or homogeneity within communities. Our main contribution is to show that there are always counteracting forces (heterogeneity involves both costs and benefits), and that, although people prefer to live in communities where their type is majoritarian, they always benefit from having some heterogeneity in the composition of their community.heterogeneity, social interactions, value of information, complementarities.

An Economic Theory of the Glass Ceiling

The glass ceiling is one of the most controversial and emotive aspects of employment in organisations. This paper provides a model of the glass ceiling that exhibits the following features that are frequently thought to characterise the problem: (i) there is a lower number of female employees in higher positions, (ii) women have to work harder than men to obtain equivalent jobs, (iii) women are then paid less than men when promoted, and (iv) some organisations are more female friendly than others. These features emerge as an equilibrium phenomenon, when identical firms compete in "Bertrand-like" fashion. Furthermore, they also occur even when offering women the same contract as men in higher positions would be sufficient to ensure that women in those positions would always prefer permanent career over non-market alternatives.Glass Ceiling, Promotions, Career Options

An Economic Theory of Glass Ceiling

In the 'glass ceiling' debate there appear to be two strongly held and opposing interpretations of the evidence, one suggesting it is really the result of gender differences and the other that there is discrimination by gender. This paper provides an economic theory of the glass ceiling and one of the main insights of our analysis is that in some real sense these two interpretations are not in conflict with each other. The glass ceiling emerges as an equilibrium phenomenon when firms compete à la Bertrand even though employers know that offering women the same contract as men would be sufficient to erase all differences among promoted workers. The model also provides new insights into anti-discrimination policy measures. (Updated from working paper 07/183)glass ceilings, promotions, career options

Why Big Theories are Fruitless, Fragmentation is Ideal, Defining Creativity is Overrated and Method-Driven Research is Urgent: Some Thoughts on the Flourishing State of Creativity Science

This comment considers Glăveanu’s observations about the state of creativity studies. I agree with Glăveanu’s view of creativity research but disagree that it is bad. The history of psychology shows that “big theories” inevitably fail to fulfill their promise. Instead, as George Kelly argued long ago, complex problems with many facets are better served by a mix of big and small theories. Likewise, the diversity of creativity research is a sign of healthy pluralism, not lamentable fragmentation. Science doesn’t proceed via central planning, and claims of “fragmentation” and “wasted effort” raise disturbing questions about who gets to decide what other scientists should study. Finally, creativity research should be more method-driven than it is. Methods are interesting in their own right, and they can be heuristics for generating good ideas as well as tools for solving problems. All told, this era of creativity research will be remembered as a period of renaissance rather than [email protected] of North Carolina at Greensboro, USA1223323

More papers, better papers? The curious correlation of quality and quantity in academic publishing

Paul J. Silvia is creeped out by the correlation between quality and quantity in academic publishing, but why do the people who publish the most also publish the work that has greatest influence
