Universal electric-field-driven resistive transition in narrow-gap Mott insulators

One of today's most exciting research frontier and challenge in condensed matter physics is known as Mottronics, whose goal is to incorporate strong correlation effects into the realm of electronics. In fact, taming the Mott insulator-to-metal transition (IMT), which is driven by strong electronic correlation effects, holds the promise of a commutation speed set by a quantum transition, and with negligible power dissipation. In this context, one possible route to control the Mott transition is to electrostatically dope the systems using strong dielectrics, in FET-like devices. Another possibility is through resistive switching, that is, to induce the insulator-to-metal transition by strong electric pulsing. This action brings the correlated system far from equilibrium, rendering the exact treatment of the problem a difficult challenge. Here, we show that existing theoretical predictions of the off-equilibrium manybody problem err by orders of magnitudes, when compared to experiments that we performed on three prototypical narrow gap Mott systems V2-xCrxO3, NiS2-xSex and GaTa4Se8, and which also demonstrate a striking universality of this Mott resistive transition (MRT). We then introduce and numerically study a model based on key theoretically known physical features of the Mott phenomenon in the Hubbard model. We find that our model predictions are in very good agreement with the observed universal MRT and with a non-trivial timedelay electric pulsing experiment, which we also report. Our study demonstrates that the MRT can be associated to a dynamically directed avalanche

Want to Hookup?: Sex Differences in Short Term Mate Attraction Tactics

While a great deal of psychological research has been conducted on sex-specific mate choice preferences, relatively little attention has been directed toward how heterosexual men and women solicit short-term sexual partners, and which acts are perceived to be the most effective. The present research relied on an act nomination methodology with the goal of determining which actions are used by men and women to solicit a short-term “hook-up” partner (study 1) and then determine which of these actions are perceived as most effective by men and women (study 2). Using sexual strategy theory, we hypothesized that actions that suggest sexual access would be nominated most often by women whereas actions that suggest a willingness to commit were expected to be nominated most often by men. Additionally, men and women were predicted to rate actions by men that suggest a willingness to commit as most effective and actions by women that suggest sexual access as most effective. The results were consistent with these hypotheses. These findings are discussed in the context of both short- and long-term mating strategies and mate solicitation. The relationship between motivation, sexual strategies, and sexual behavior are examined, along with the need for research on the hookup tactics and motivations of self-identifying gay, lesbian, and bisexual individuals

Human Nature and Pop Culture

He who understands baboon would do more toward metaphysics than Locke. Charles Darwin, M Notebook, 1838 You might be asking yourself, why a special issue on evolutionary approaches to studying popular culture? After all, isn't evolutionary psychology focused on reproductive success and the ancestral environment? The aspects of pop culture featured in this issue, such as TV shows and horror films, were not a feature of our ancestral world. They don't seem to directly relate to reproductive success. They don't have obvious ties to the environment (whether it be geographical or temporal) in which we evolved. So, what could an evolutionary perspective possibly add to our understanding of them as aspects of our modern world? The punch line is that we created these media products using our evolved brains, and that we interact with them using these brains. There might not actually be werewolves running around New York City, but we evolved the capacity to imagine them, to consider problems that need solutions, and to play out situations that evoke a sense of astonishment. Indeed, there are many aspects of our modern environment and our behavior that are best understood under the light of an evolutionary perspective. For example, much attention has been focused in recent years on the increase in obesity, especially in the United States, and how one possible cause includes the overconsumption of fast food. The reality is, that for millions of years, humans who stored fat during times of abundance had an advantage over others when food was scarce, and hence they were favored by natural selection. A taste for fatty and sweet foods would also have been favored by natural selection, as they were relatively rare (e.g., honey, ripe fruit) or required hard work to obtain (e.g., hunting for meat) and yet were important sources of calories Evolutionary approaches have already been used in the fields of literary theory and art. The field of Darwinian literary studies, which is quickly gaining considerable momentum, has provided evidence that humankind's evolved history influences the topics of texts Like pop culture, literary theory (and the study of art) has been dominated by a variety of perspectives, such as social constructivism, postmodernism, and deconstructionism (including Marxist, feminist, and psychoanalytic frameworks), which have focused more on a blank-slate view of human behavior. Even those working within these fields have commented on the stagnation that has resulted from this narrow perspective of human behavior (e.g., Carroll, 1995). Psychologists should not be surprised; after all, Freud and Lacan, e.g., are basically footnotes in our understanding of human behavior in modern psychology programs. We've achieved a better understanding of the human mind since the 1930s (which was the last decade of Freud's life). At last, the study of literature and art is starting to benefit from the work of those who are applying that new understanding. For examples from the literary and art fields, there are a number of anthologies including to its appeal to universal aspects of human nature, and how much is due to other factors (such as attached prestige, celebrity of promoters, etc.)? By using evolution to inform our scholarly endeavors, we arrive at a far more satisfying and comprehensive understanding (see Saad, this issue for a general review of these issues, as well as for a detailed discussion on the success and the resistance to the evolutionary framework)

Learner Presence Matters: A Learner-Centered Exploration into the Community of Inquiry Framework

In the present study we explored the Community of Inquiry (CoI) framework, a theoretical structure identifying processes leading to effective online learning, within one particular learning context. Drawing from research supporting the significance of three presences—teaching, social, cognitive presence—we add to a line of research on a potential fourth presence, learner presence. We employed a mixed-method approach to investigate learner perceptions, thoughts, and actions in MBA online/blended courses. Stimulated recall interviews with individual learners regarding their course experience highlighted three qualities of the learners’ presence in their courses: intentions, metacognition, and peer monitoring. They also pointed to ways in which certain facets of the three CoI presences supported these qualities. The findings prompted questions for further CoI research investigating learner presence and suggested implications for learner-centered course design and online instruction.

Atopic dermatitis studies through in vitro models

Atopic dermatitis (AD) is a complex inflammatory skin condition that is not fully understood. Epidermal barrier defects and Th2 immune response dysregulations are thought to play crucial roles in the pathogenesis of the disease. A vicious circle takes place between these alterations, and it can further be complicated by additional genetic and environmental factors. Studies investigating in more depth the etiology of the disease are thus needed in order to develop functional treatments. In recent years, there have been significant advances regarding in vitro models reproducing important features of AD. However, since a lot of models have been developed, finding the appropriate experimental setting can be difficult. Therefore, herein, we review the different types of in vitro models mimicking features of AD. The simplest models are two-dimensional culture systems composed of immune cells or keratinocytes, whereas three-dimensional skin or epidermal equivalents reconstitute more complex stratified tissues exhibiting barrier properties. In those models, hallmarks of AD are obtained, either by challenging tissues with interleukin cocktails overexpressed in AD epidermis or by silencing expression of pivotal genes encoding epidermal barrier proteins. Tissue equivalents cocultured with lymphocytes or containing AD patient cells are also described. Furthermore, each model is placed in its study context with a brief summary of the main results obtained. In conclusion, the described in vitro models are useful tools to better understand AD pathogenesis, but also to screen new compounds in the field of AD, which probably will open the way to new preventive or therapeutic strategies

A Cross-Disciplinary Survey of Beliefs about Human Nature and Culture.

How far has the Darwinian revolution come? To what extent have evolutionary ideas penetrated into the social sciences and humanities? Are the “science wars” over? Or do whole blocs of disciplines face off over an unbridgeable epistemic gap? To answer questions like these, contributors to top journals in 22 disciplines were surveyed on their beliefs about human nature, culture, and science. More than 600 respondents completed the survey. Scoring patterns divided into two main sets of disciplines. Genetic influences were emphasized in the evolutionary social sciences, evolutionary humanities, psychology, empirical study of the arts, philosophy, economics, and political science. Environmental influences were emphasized in most of the humanities disciplines and in anthropology, sociology, education, and women’s or gender studies. Confidence in scientific explanation correlated positively with emphasizing genetic influences on behavior, and negatively with emphasizing environmental influences. Knowing the current actual landscape of belief should help scholars avoid sterile debates and ease the way toward fruitful collaborations with neighboring disciplines
