Sexual selection drives the evolution of some of the most exaggerated traits in nature. Studies on sexual selection often focus on the size of these traits relative to body size, but few focus on energetic maintenance costs of the tissues that compose them, and the ways in which these costs vary with body size. The relationships between energy use and body size have consequences that may allow large individuals to invest disproportionally more in sexually selected structures, or lead to the (...) reduced per‐gram maintenance cost of enlarged structures. Although sexually selected traits can incur energetic maintenance costs, these costs are not universally high; they are dependent on the relative mass and metabolic activity of tissues associated with them. Energetic costs of maintenance may play a pervasive yet little‐explored role in shaping the relative scaling of sexually selected traits across diverse taxa.

Ideological briefings on the causes which lead to the down fall of Muslims.

Religious Reflection Scales yield cross-cultural data suggesting that religious traditions have potentials to integrate intellect with faith. This investigation extended analysis of that possibility to Sunni Muslim university students in Malaysia and also examined the hypothesis that Islamic commitments to knowledge promote religious openness. Faith and Intellect Oriented Religious Reflection correlated positively and predicted openness. The Truth of Texts and Teachings factor from the Religious Schema Scales essentially assesses a form of fundamentalism and displayed direct linkages with religious openness as (...) well. Ilm factors from the Ummatic Personality Inventory correlated positively with religious openness and mediated associations of Islamic Religious Reflection with other constructs. Quest as a presumed index of religious openness proved to be incompatible with sincere Muslim commitments. These findings supplemented previous Muslim, Christian, and Hindu data in confirming the potential openness of religious traditions. (shrink)

This article reevaluates the Iranian polymath Ali Shariati’s most controversial lectures. Scholarly consensus reads 1969’s Ummat va Imāmat as derivative, comprising an imitation of Sukarno’s guided democracy and hence an apology for postcolonial authoritarian rule. Shariati’s rhetorical performance suggests otherwise. The lectures address a postcolonial iteration of Jean-Jacques Rousseau’s paradox of founding—a call for self-determination alongside the external intervention needed to prepare for it in the wake of moral dispositions accrued during colonization. Shariati proposes to resolve the problem of (...) enduring colonial domination by citing a fabricated French professor, a foreigner, as an authoritative source. He practices a noble lie, believable because it draws from colonized sensibilities but laden with hints encouraging audiences to see past it. If audiences develop the requisite ability to decipher the lie, Shariati wagers, they at once develop the autonomy implied by self-determination. On these grounds, Shariati theorizes the paradox of politics as decolonization. (shrink)
