A Proposed Process for Managing the First Amendment Aspects of Campus Hate Speech
For public institutions, attempts to regulate hate speech raise substantial legal issues under the First Amendment of the U.S. Constitution. For private institutions, which may not be bound by the First Amendment, attempts to regulate hate speech raise sensitive policy questions concerning the role of free expression on campus. Numerous articles (many of which are listed in the references below) have undertaken substantive analysis of these constitutional issues and policy questions. In contrast, this article explores a preliminary and overarching concern: the process by which a college or university addresses the problem of hate speech, and in particular the process by which the institution manages the First Amendment aspects of the problem. In other words, this article focuses on the decision-making process rather than on the decisions themselves; it is the journey, not the destination, that is of primary concern

Harnessing learning biases is essential for applying social learning in conservation
Social learning can influence how animals respond to anthropogenic changes in the environment, determining whether animals survive novel threats and exploit novel resources or produce maladaptive behaviour and contribute to human-wildlife conflict. Predicting where social learning will occur and manipulating its use are, therefore, important in conservation, but doing so is not straightforward. Learning is an inherently biased process that has been shaped by natural selection to prioritize important information and facilitate its efficient uptake. In this regard, social learning is no different from other learning processes because it too is shaped by perceptual filters, attentional biases and learning constraints that can differ between habitats, species, individuals and contexts. The biases that constrain social learning are not understood well enough to accurately predict whether or not social learning will occur in many situations, which limits the effective use of social learning in conservation practice. Nevertheless, we argue that by tapping into the biases that guide the social transmission of information, the conservation applications of social learning could be improved. We explore the conservation areas where social learning is highly relevant and link them to biases in the cues and contexts that shape social information use. The resulting synthesis highlights many promising areas for collaboration between the fields and stresses the importance of systematic reviews of the evidence surrounding social learning practices.BBSRC David Phillips Fellowship (BB/H021817/1
Vascular and blood-brain barrier-related changes underlie stress responses and resilience in female mice and depression in human tissue
Prevalence, symptoms, and treatment of depression suggest that major depressive disorders (MDD) present sex differences. Social stress-induced neurovascular pathology is associated with depressive symptoms in male mice; however, this association is unclear in females. Here, we report that chronic social and subchronic variable stress promotes blood-brain barrier (BBB) alterations in mood-related brain regions of female mice. Targeted disruption of the BBB in the female prefrontal cortex (PFC) induces anxiety- and depression-like behaviours. By comparing the endothelium cell-specific transcriptomic profiling of the mouse male and female PFC, we identify several pathways and genes involved in maladaptive stress responses and resilience to stress. Furthermore, we confirm that the BBB in the PFC of stressed female mice is leaky. Then, we identify circulating vascular biomarkers of chronic stress, such as soluble E-selectin. Similar changes in circulating soluble E-selectin, BBB gene expression and morphology can be found in blood serum and postmortem brain samples from women diagnosed with MDD. Altogether, we propose that BBB dysfunction plays an important role in modulating stress responses in female mice and possibly MDD
Modeling the Past: The Paleoethnological Evidence
This chapter considers the earliest Paleolithic, Oldowan (Mode 1), and Acheulean (Mode 2)
cultures of the Old Continent and the traces left by the earliest hominids since their departure
from Africa. According to the most recent archaeological data, they seem to have followed two
main dispersal routes across the Arabian Peninsula toward the Levant, to the north, and the Indian
subcontinent, to the east. According to recent discoveries at Dmanisi in the Caucasus, the first
Paleolithic settlement of Europe is dated to some 1.75 Myr ago, which indicates that the first “out of
Africa” took place at least slightly before this date. The data available for Western Europe show
that the first Paleolithic sites can be attributed to the period slightly before 1.0 Myr ago. The first
well-defined “structural remains” so far discovered in Europe are those of Isernia La Pineta in
Southern Italy, where a semicircular artificial platform made of stone boulders and animal bones
has been excavated. The first hand-thrown hunting weapons come from the site of Scho¨ningen in
north Germany, where the first occurrence of wooden spears, more than 2 m long, has been
recorded from a site attributed to some 0.37 Myr ago. Slightly later began the regular control of
fire. Although most of the archaeological finds of these ages consist of chipped stone artifacts,
indications of art seem to be already present in the Acheulean of Africa and the Indian
subcontinent
