CHAPTER 8: DWIGHT READ: TOWARDS A NEW PARADIGM: FOLLOWED BY A DISCUSSION BETWEEN THE AUTHOR AND DWIGHT READ

Here I report on Dwight Read’s theory for a paradigm change in kinship anthropology which entails kinship terminologies being interpreted as symbolic computational systems based on kin-term products. I also report on how Read argues that different conceptualizations of sibling, either sibling resulting by descent from parent, or sibling viewed in terms of shared parentage, two cultural conceptions that are rendered – here exemplifying the masculine side – by the kin-term products, S o F = B [son of father = brother] or F o B = F [father of brother = father), lead to respectively building up a descriptive or a classificatory terminology. The chapter also deals with how Dwight Read accounts for the relationship between genealogical tracing and the working out of kin terms using kin-term products and how the logic of kin-term products is consistent with the extension of kin terms to kin-type categories beyond the primary ones.The paper also reports on a discussion between Dwight Read and the author, initiated by questions and observations from the latter, regarding different aspects of Read’s reasoning. Not exhaustively, to be mentioned here is the way kin relationships are concretely worked out using kin-term products, the model of the family space and the nuclear family, group marriage,  how the conceptualization of sibling in terms of shared parentage expressed through the kin-term product F o B = F [father o brother = father] relates to ethnographic data, the nature of the logic of kinship terminologies, the status of the structural equation S o F = B [son o father = brother] when used within the context of a classificatory terminology, the axiomatic nature of a number of kin-term products pertaining to specific kin terminologies, the equations pertaining to classificatory kinship terminologies that are  likely to algebraically reduce chains of kin-terms products, mapped from corresponding kin type strings, like “son of son of father of father of father” (S o S o F o F o F) is mapped from the collateral genealogical relations, father’s father’s father’s son’s son (fffss or fffbss) to an irreducible kin term, here father, which is the one native speakers use for the said genealogical connection.The discussion also addresses, taking the example of ancient Chinese dialects, the question of what should be the structural prerequisites for a transition from classificatory (Dravidian) terminologies into bifurcate collateral and descriptive terminologies, a transition that is often posited by a number of linguists and anthropologists. Finally, the discussion deals with the question as to whether the kinship terminologies of the world all ultimately derive from a pre-dispersal African Proto-Sapiens kinship terminology. Throughout these lines of discussion, the central question is raised as to why different cultural choices on how siblings are conceptualized were made that led to different human kinship terminologies and social structures

Continuous matter creation and the acceleration of the universe: the growth of density fluctuations

Cosmologies including continuous matter creation are able to reproduce the main properties of the standard $\Lambda$CDM model, in particular in cases where the particle and entropy production rates are equal. These specific models, characterized by a mass density equal to the critical value, behave like the standard $\Lambda$CDM model at early times whereas their late evolution is similar to the steady-state cosmology. The maximum amplitude of density fluctuations in these models depends on the adopted creation rate, related here to the parameter $\Omega_v$ and this limitation could be a difficulty for the formation of galaxies and large-scale structure in this class of universe. Additional problems are related with predictions either of the random peculiar velocities of galaxies or the present density of massive clusters of galaxies, both being largely overestimated with respect to observational data.Comment: 11 pages, 2 figures, accepted for publication in General Relativity and Gravitatio

Topological 2-Dimensional Quantum Mechanics

We define a Chern- Simons Lagrangian for a system of planar particles topologically interacting at a distance. The anyon model appears as a particular case where all the particles are identical. We propose exact N-body eigenstates, set up a perturbative algorithm, discuss the case where some particles are fixed on a lattice, and also consider curved manifolds.

Wage and employment effects of a wage norm : The Polish transition experience

Most transition countries used tax-supported wage norms in the early 1990's, as a part of their market liberalization programs. This paper analyses how a firm-level tax (or subsidy) on deviations from a pre-set wage norm may promote employment by rotating the labor demand curve perceived by the workers' union around the value of the norm. We derive the conditions such that it yields a positive employment effect. We test the effect of the norm on the wages on a sample of Polish firms in 1990 and 1991. The data support the role of the wage norm on the position of the perceived labor demand and the role of the tax rate on its slope.transition economies, labor market, unions, excess wage tax, employment

One-Dimensional Statistical Mechanics for Identical Particles : The Calogero and Anyon Cases

The thermodynamic of particles with intermediate statistics interpolating between Bose and Fermi statistics is adressed in the simple case where there is one quantum number per particle. Such systems are essentially one-dimensional. As an illustration, one considers the anyon model restricted to the lowest Landau level of a strong magnetic field at low temperature, the generalization of this model to several particles species, and the one dimensional Calogero model. One reviews a unified algorithm to compute the statistical mechanics of these systems. It is pointed out that Haldane's generalization of the Pauli principle can be deduced from the anyon model in a strong magnetic field at low temperature.Comment: 17 page

Flourish or Fail?: The Risky Reward of Elite High School Admission in Mexico City

Admission to an elite school imposes substantial risks on many students while offering modest academic benefits relative to admission in their most preferred nonelite school. Using variation in school assignment generated by the allocation mechanism, we find that admission to a system of elite public high schools in Mexico City increases the probability of high school dropout by 9.4 percentage points. Students with weaker middle school grades and whose commutes are lengthened by elite admission experience a larger rise in dropout probability. On the other hand, elite admission raises end-of-high-school math test scores for the marginal admittee, even when accounting for potential bias due to admission-induced dropout

Toward a Territorial Approach to Rural Development

This paper explores a territorial approach to rural development in Latin America. It first reviews evidence that progress in rural social development has not been accompanied by reductions in income poverty and inequality. It then assesses qualitative changes that have occurred in rural incomes and the emergence of new opportunities for rural poverty reduction and draws implications for the potential of a territorial approach to rural development. Recent experiences with territorial approaches are briefly reviewed and lessons extracted for the implementation of such an approach. It concludes with a series of recommendations for implementation of a territorial approach to rural development.rural development, rural poverty, territorial approach, inequality, Latin America, Community/Rural/Urban Development, O10, O13, O15, O18,
