On the human capital of Inca Indios before and after the Spanish conquest: Was there a "pre-colonial legacy"?

Not only the colonial period, but also the pre-colonial times might have influenced later development patterns. In this study we assess a potential pre-colonial legacy hypothesis for the case of the Andean region. In order to analyze the hypothesis, we study the human capital of Inca Indios, using age-heaping-based techniques to estimate basic numeracy skills. We find that Peruvian Inca Indios had only around half the numeracy level of the Spanish invaders. The hypothesis holds even after adjusting for a number of potential biases. Moreover, the finding has also crucial implications for the narrative of the military crisis of the Inca Empire. A number of explanations have been given as to why the Old American Empires were not able to defend their territory against the Spanish invaders in the early 16th century. We add an economic hypothesis to the debate and test it with new evidence: Were the human capital formation efforts of the Inca economy perhaps too limited, making it difficult to react appropriately to the Spanish challenge? --human capital,age-heaping,Inca empire,inequality,growth

Gods, Heroes, & Kings: The Battle for Mythic Britain

The islands of Britain have been a crossroads of gods, heroes, and kings-those of flesh as well as those of myth-for thousands of years. Successive waves of invasion brought distinctive legends, rites, and beliefs. The ancient Celts displaced earlier indigenous peoples, only to find themselves displaced in turn by the Romans, who then abandoned the islands to Germanic tribes, a people themselves nearly overcome in time by an influx of Scandinavians. With each wave of invaders came a battle for the mythic mind of the Isles as the newcomer\u27s belief system met with the existing systems of gods, legends, and myths.In Gods, Heroes, and Kings, medievalist Christopher Fee and veteran myth scholar David Leeming unearth the layers of the British Isles\u27 unique folkloric tradition to discover how this body of seemingly disparate tales developed. The authors find a virtual battlefield of myths in which pagan and Judeo-Christian beliefs fought for dominance, and classical, Anglo-Saxon, Germanic, and Celtic narrative threads became tangled together. The resulting body of legends became a strange but coherent hybrid, so that by the time Chaucer wrote The Wife of Bath\u27s Tale in the fourteenth century, a Christian theme of redemption fought for prominence with a tripartite Celtic goddess and the Arthurian legends of Sir Gawain-itself a hybrid mythology.Without a guide, the corpus of British mythology can seem impenetrable. Taking advantage of the latest research, Fee and Leeming employ a unique comparative approach to map the origins and development of one of the richest folkloric traditions. Copiously illustrated with excerpts in translation from the original sources,Gods, Heroes, and Kings provides a fascinating and accessible new perspective on the history of British mythology.

Boom‐bust dynamics in biological invasions: towards an improved application of the concept

Boom‐bust dynamics – the rise of a population to outbreak levels, followed by a dramatic decline – have been associated with biological invasions and offered as a reason not to manage troublesome invaders. However, boom‐bust dynamics rarely have been critically defined, analyzed, or interpreted. Here, we define boom‐bust dynamics and provide specific suggestions for improving the application of the boom‐bust concept. Boom‐bust dynamics can arise from many causes, some closely associated with invasions, but others occurring across a wide range of ecological settings, especially when environmental conditions are changing rapidly. As a result, it is difficult to infer cause or predict future trajectories merely by observing the dynamic. We use tests with simulated data to show that a common metric for detecting and describing boom‐bust dynamics, decline from an observed peak to a subsequent trough, tends to severely overestimate the frequency and severity of busts, and should be used cautiously if at all. We review and test other metrics that are better suited to describe boom‐bust dynamics. Understanding the frequency and importance of boom‐bust dynamics requires empirical studies of large, representative, long‐term data sets that use clear definitions of boom‐bust, appropriate analytical methods, and careful interpretations

Alien plants in urban nature reserves : from red-list species to future invaders?

Urban reserves, like other protected areas, aim to preserve species richness but conservation efforts in these protected areas are complicated by high proportions of alien species. We examined which environmental factors determine alien species presence in 48 city reserves of Prague, Czech Republic. We distinguished between archaeophytes, i.e. alien species introduced since the beginning of Neolithic agriculture up to 1500 A. D., and neophytes, i.e. modern invaders introduced after that date, with the former group separately analysed for endangered archaeophytes (listed as C1 and C2 categories on national red list). Archaeophytes responded positively to the presence of arable land that was in place at the time of the reserve establishment, and to a low altitudinal range. In addition to soil properties, neophytes responded to recent human activities with the current proportion of built-up area in reserves serving as a proxy. Endangered archaeophytes, with the same affinity for past arable land as other archaeophytes, were also supported by the presence of current shrubland in the reserve. This suggests that for endangered archaeophytes it may have been difficult to adapt to changing agricultural practices, and shrublands might act as a refugium for them. Forty-six of the 155 neophytes recorded in the reserves are classified as invasive. The reserves thus harbour 67% of the 69 invasive neophytes recorded in the country, and particularly worrisome is that many of the most invasive species are shrubs and trees, a life form that is known to account for widespread invasions with high impacts. Our results thus strongly suggest that in Prague nature reserves there is a high potential for future invasions

Ugarit

In 1928 a Syrian peasant farmer stumbled by chance onto a funerary vault of ancient provenance about half a mile from the Mediterranean coastline of Syria and about six miles north of the modern-day city of Latakia. This unforeseen discovery led to an archaeological excavation ofTell Ras Shamra (Cape Fennel) by the eminent French excavator Claude Schaeffer. What Schaeffer\u27s team unearthed was not merely an ancient tomb, but a city complete with palaces, private homes, temples, and streets paved with stone
