The Convergence-Divergence Hypothesis - ResearchGate

This paper examines the impact ofworkforce demographics on aggregate productivity. The age structure ofthe workforce is found to have a significant impact on aggregate productivity. Alarge cohort of workers aged 40 to 49 is found to have a large positive impacton productivity. Out of sample predictions of output growth from 1990 to1995 predict 17% of actual output growth differences across a sample of 108countries. The results suggest a partial explanation for the productivityslowdown in the seventies and the boom in the nineties. This paperestimates that productivity growth in the seventies was 2% lower than trend due to the entryof the baby boom into the workforce. As the baby boomers entered theirforties in the nineteen eighties and nineties, productivity growthrebounded. Japanese demographics predict almost the opposite pattern,with high growth in the seventies followed by low growth in the nineties. Demographics can also explain part of the productivity divergence between richand poor nations between 1960 and 1990.

The Convergence Hypothesis: Types and Paths | …

The concept of convergence and divergence are clearly defined within two distinct paradigms of ER

It will only give the convergence/divergence of the series

In the present study, we have investigated the characteristics of interactive strategies of Convergence, Divergence and Maintenance in subjects suffering from OCD. The results showed that these patients over-relied, in communicating, on oblique strategies of Maintenance. This issue is consistent with the hypothesis of a “rigidity” of the communicative style in patients with OCD, which led these subjects to link communication to their own conversational turns, often neglecting the communicative contributions of the partner.

Conversely, the Compulsion subscale gives more defined results: it is associated with the Maintenance by the only significant correlation observed. Furthermore, the Compulsion is quite independent from the Solicitation index (i.e.: Convergence) and is weakly related with indexes of Balance and Fragmentation. This led us to hypothesize that tendency to Compulsion, showed by people with OCD, is exclusively related to the strategy of Maintenance.

As shown in the sample of the interview, turns 2, 6, 11, 15 and 17 report index codes to calculate the coefficient B, i.e., the convergence. These turns represent both response and initiative. The speaker links to the antecedent turn of the partner, so contributing to the harmony of the ongoing communicative act. The turns 4, 7, 9, 14, 18, 20, 21, 22, 24 and 26 are coded by indexes to calculate coefficient O. These turns represent the tendency to re-link to own adjacent turns by the speaker, or to link to arguments close within the conversation. In the last case, it is evident that the speaker does not take into account the partner’s contribution, because the partner is often interrupted, or he is only marginally involved by means of so-called non-focal linking. As a matter of fact, the turn 26 is coded as self-linking: the speaker comes back on a topic to which he had always answered by turns 1 - 14.

The east-west differences persist until at least 350 Kyr. At this time, elements of a Mode 2 industry (bifaces, possible retouched cleavers) may be present at the site of Dingcun in northern China, but these never show the standardized form of the western Acheulian (Clark & Schick 1988). Mode I industries continue in southern China. In southeast Asia, associations between hominid occupation and stone tools can be documented only for the Kabuh levels, and these are simple Model flakes (Simanjuntak & Semah 19%). Between 350—250 ICyr, Mode 2 industries dominate in Europe (Gamble 1986). Regional fragmentation of Mode 2 industries also seems to occur: the Levantine Mode 2 differentiates into the Acheulo-Yabrudian (Bar-Yosef 1993); in sub-Saharan Africa into forms like the southern African Fauresmith, the Dakia, Langoan, and Sangoan (Clark, J.D. 1992). Mode 3 is essentinily a core preparation and reduction refinement. Early manifestations{>250 Kyr) are found in Africa and Europe. The African Victoria West perhaps represents the earliest diagnostically distinctive form of Levallois-style core preparation. In contrast, the European record shows a more complex process involving, on the one hand, reduction in handaxe size, to converge on Levallois cores, and on the other, a patchy appearance of Levallois technique with a continuing Acheulean tradition (Fig. 4C).

Discusses the process and terminology of problem solving.

Although disputed (e.g. Arensburg 1990 et al.; Clark & Lindly 1989), this was a major departure from the previous orthodoxy, which stressed the essentially human nature of archaic hominids (Isaac 1978). The link with the modem human origins debate is the expectation that an ancient divergence between modern humans and Neanderthals will be correlated with major behavioural differences, a low probability of inter-breeding, and a higher probability of replacement. The MM, proposing high levels of gene flow, has thus become associated with archaeological interpretations that stress the similarities between Neanderthals and modern humans, while the SOM, proposing replacement, has required substantial differences as a mechanism for explaining modern human success. In effect this means that the archaeological record will support the SOM when it shows discontinuities in behaviour between archaics, especially Neanderthals, and modern humans, for it is inferred that the greater the differences, the less likely gene flow will have occurred. The inferred cognitive and behavioural differences then become the explanatory basis for the success of modern humans relative to Neanderthals — more efficient use of technology and resources, or else more secure social and psychological adaptations. Cognition has perhaps been the crux of the archaeojpgical debate for it may be differences in neurobiology that will link inferred behavioural capacities to some sort of biological and evolutionary basis. The role of archaeology has thus been to emphasize q~iestions of function, behaviour and cognition. In contrast, biologists have focused largely on phylogenetic reconstruction — the history of population relationships. The contrast between the functional and adaptive interests of most archaeologists and the genealogical concerns of most biologists is striking. The question we would pose here is: What happens if the approaches are reversed, archaeological data are treated as a primary source of phylogenetic information about recent human evolution?
