Space Trumps Time When Talking About Objects

The nature of the relationship between the concepts of space and time in the human mind is much debated. Some claim that space is primary and that it structures time (cf. Lakoff & Johnson, 1980) while others (cf. Walsh, 2003) maintain no difference in status between them. Using fully immersive virtual reality (VR), we examined the influence of object distance and time of appearance on choice of demonstratives (this and that) to refer to objects. Critically, demonstratives can be used spatially (this/that red triangle) and temporally (this/that month). Experiment 1 showed a pattern of demonstrative usage in VR that is consistent with results found in real‐world studies. Experiments 2, 3, and 4 manipulated both when and where objects appeared, providing scenarios where participants were free to use demonstratives in either a temporal or spatial sense. Although we find evidence for time of presentation affecting object mention, the experiments found that demonstrative choice was affected only by distance. These results support the view that spatial uses of demonstratives are privileged over temporal uses

Rate theory for correlated processes: Double-jumps in adatom diffusion

We study the rate of activated motion over multiple barriers, in particular the correlated double-jump of an adatom diffusing on a missing-row reconstructed Platinum (110) surface. We develop a Transition Path Theory, showing that the activation energy is given by the minimum-energy trajectory which succeeds in the double-jump. We explicitly calculate this trajectory within an effective-medium molecular dynamics simulation. A cusp in the acceptance region leads to a sqrt{T} prefactor for the activated rate of double-jumps. Theory and numerical results agree

The dick pic : harassment, curation, and desire

The combined rise of digital photography and social media has expanded what might be considered photo worthy. Among the pouting selfies and food stuffs of the day exists the ubiquitous dick pic. The mainstream media generally focuses on dick pics of the unsolicited kind, which, negatively positioned, are commonly associated with heterosexual harassment. Considering the ubiquity of dick pics across apps and platforms, research on the topic nevertheless remains scarce. In this article, we examine the dick pic as an online communicative form, first considering how it manifests the ability to harass and then moving beyond this dominant framing to analysis of contexts where such images are collated, expected, and sought after. Through this analysis of dick pics as figures and actors of harassment, curation, and desire, we demonstrate the simultaneous tenacity and flexibility of their meanings in connection with the dynamics of consent and non-consent, intimacy and distance, and complex circuits of desire. We further address the role of platforms, apps, and app stores, via their community standards and terms of use, in shaping the nature, and presence, of dick pics, and discuss the affective and communicative functions that these affordances serve (or fail to serve). Our analysis of three key modes of engagement with dick pics demonstrates the ambiguity and multiple valences of the phenomenon addressed

Mechanical and Anatomical Properties in Individual Growth Rings of Plantation-Grown Eastern Cottonwood and Loblolly Pine

Growth in genetically improved trees under intensive management is so rapid that rotations may be as short as 20 to 30 years. At that age, the trees contain a high proportion of lower quality juvenile wood. Thus, the properties of juvenile wood need to be characterized to effectively use this resource.This study determined relationships between age and mechanical and anatomical properties, the average properties of juvenile and mature wood, the age of demarcation between juvenile and mature wood, and the projected proportions of juvenile and mature wood at various ages in plantation cottonwood and loblolly pine. It also compared projected properties of plantation trees with those published for trees from natural forests.All properties improved markedly with age, up to nearly a tenfold increase in modulus of elasticity of one loblolly pine tree from early juvenile wood to late mature wood. Average mechanical properties of juvenile wood ranged from 47% to 63% of those for mature wood in pine and from 62% to 79% in cottonwood. The age of demarcation between juvenile and mature wood varied by species and property, ranging from 13 to 20 years. At age 40, plantation trees sampled were projected to contain approximately 25% juvenile wood. The mechanical properties of the pine were projected to approximate those of trees from natural forests at 30 to 60 years, depending on property, while those for cottonwood will not achieve comparability

The Ethnographic Use of Facebook in Everyday Life

New social media have become indispensable to people all over the world as platforms for communication, with Facebook being the most popular. Hence, platforms such as Facebook are also becoming crucial tools for ethnographers because much social life now exists ‘online’. What types of field relations stem from such social media-driven ethnography? And what kinds of data do these relations present to the ethnographer? These questions must be considered in order to understand the challenges Facebook and other social media pose to ethnographic methodology. This article focuses on how Facebook may play an important role even in ethnographic work concerned with questions other than how Facebook works as a social medium. Most importantly it allows the ethnographer to keep up-to-date with the field. I argue that ethnography is already in possession of the methodological tools critically to assess the validity and value of data gathered or produced via Facebook including issues such as authenticity which are also pertinent to digital ethnography

Isolation of Lactoferrin and its Concentration in Sows’ Colostrum and Milk During a 21-Day Lactation

Levels of lactoferrin, an Fe-binding protein with bacteriostatic properties, were determined in the colostrum and milk of Yorkshire sows during a 21-d lactation. Lactoferrin levels averaged 1,100 to 1,300 μg/ml near the time of farrowing, then declined sharply during the first week of lactation. Concentration of lactoferrin showed considerable variation among sows, but not among teat positions (anterior to posterior). A method for isolating high purity swine lactoferrin is described

Constructing the digitalized sporting body: black and white masculinity in NBA/NHL internet memes

In this article, I examine the ways sport fans construct and circulate discourses of race and masculinity in cyberspace. I do this through an examination of a set of Internet memes that juxtapose the bodies of National Hockey League players with National Basketball Association players in one single image. I argue these memes celebrate White masculinity, while at the same time constructing African American athletes as individualistic, selfish, and unwilling to sacrifice their bodies for the greater good of the team. More so, I argue that these memes construct a form of racial ideology that is representative of White backlash politics
