In Africa and western Eurasia, occurrences of burials and utilized ocher fragments during the late Middle and early Late Pleistocene are often considered evidence for the emergence of symbolically-mediated behavior. Perhaps less controversial for the study of human cognitive evolution are finds of marine shell beads and complex designs on organic and mineral artifacts in early modern human (EMH...
In the transition to a market economy we examine the relationship between inherited human capital structures and the evolution of unemployment within a two-sector model of endogenous restructuring. We find evidence across Polish regions for the predictions of our theory. The inherited dominance of ineffective human capital in eastern regions of Poland has delayed restructuring, reduced unemploy...
an animal disease which he called 'cowpox'. This paper discusses recent evidence concerning the natural history of cowpox which suggests that earlier views on it may have been incorrect. In the 19th century valuable information was obtained about cowpox. However these studies in part pre-dated acceptance of the germ theory of disease, and all pre-dated the development of laboratory techniques. ...
Investigation result The Committee concludes that further investigation of the findings set out in the “Report on STAP Cell Research Paper Investigation” of March 31, 2014 (“Investigation Report”) is unnecessary, having considered the purport of the appeal and its reasons, as well as the submitted Supplementary Document 1 (supplementary document to the Appeal Document dated April 20, 2014) and ...
Shakespeare's Romeo and Juliet starts out as a classic love story: boy meets girl, boy falls in love with girl, boy and girl get married. Of course, it turns into a tragedy when they realize that their relationship is destined to fail. Surprisingly, many offices in corporate America follow a similar-though less morbid--trend. A 2005 survey revealed that 58% of employees had dated someone at wor...
Standard working memory (WM) updating tasks confound updating requirements with generic WM functions. We introduce a method for isolating a process unique to WM updating, namely the removal of no-longer relevant information. In a modified version of an established updating paradigm, tobe-updated items were cued before the new memoranda were presented. Longer cue-stimulus intervals—that is, long...
In dendrochronology wood samples are dated according to the tree rings they contain. The dating process consists of comparing the sequence of tree ring widths in the sample to a dated master sequence. Assuming that a tree forms exactly one ring per year a simple sliding algorithm solves this matching task. But sometimes a tree produces no ring or even two rings in a year. If a sample sequence c...
The role of climate change in the development and demise of Classic Maya civilization (300 to 1000 C.E.) remains controversial because of the absence of well-dated climate and archaeological sequences. We present a precisely dated subannual climate record for the past 2000 years from Yok Balum Cave, Belize. From comparison of this record with historical events compiled from well-dated stone mon...
A great tradition in macroevolution and systematics has been the ritual squabbling between palaeontologists and molecular biologists. But, because both sides were talking past each other, they could never agree. Practitioners in both fields should play to their strengths and work together: palaeontologists can provide minimum constraints on branching points in the Tree of Life with considerable...
