Education for All: How Much Will It Cost?

In 1990, a target of universal access to basic education by the year 2000 was set by two global conferences. Ten years later, however, it was clear that the target had not been met. Too many countries had made insufficient progress, and although many of the reasons for this inadequate progress were country‐specific, one factor stood out in virtually all countries: inadequate public finance for primary education. In 2000, the Millennium Summit set a new target date for achieving ‘education for all’ of 2015. This article updates the global and regional cost estimates for reaching that target. The estimates are based on the most recent country‐by‐country data on budgetary expenditure, population and enrolment trends, and unit cost. The annual additional cost of achieving ‘education for all’ in developing countries by 2015 is estimated at US$ 9.1 billion. Although this is affordable at the global level, individual countries will need considerably more resources than are currently available. However, official development assistance (ODA) has been declining, and the share of ODA allocated to basic education has changed little over the past decade. Therefore, although affordable, the target of universal basic education by 2015 is likely to be missed, just as it was in 2000, without a major change both in ODA and national budgets.     

Metallurgical traditions and metal exchange networks in late prehistoric central Myanmar,c. 1000 BC to c. AD 500

Myanmar has been notably underrepresented in recent studies of archaeometallurgy in Southeast Asia, despite its richness in both mineral and cultural resources and its potentially central role in long-distance exchange networks linking India, China and peninsular neighbours. Here, we present original analytical data on copper-base artefacts from several Bronze Age and Iron Age sites in Myanmar. Observed microstructures range from as-cast, worked, to fully annealed; compositions include leaded copper, low-tin to high-tin bronzes, and arsenical copper/bronze. Lead isotope analyses indicate that the metal originates from different geological sources, including several that match the lead isotope signatures of known prehistoric copper mines in Thailand and Laos. These archaeometallurgical data, including evidence for secondary copper-base production, more than double those currently available for Myanmar and document the presence of multiple local alloying and working traditions, perhaps chronologically differentiated, as well as identifying possible links to primary mineral sources across the region. Overall, this adds significant new information to the emerging picture of Southeast Asian prehistoric metallurgy at the crossroads of several major ancient cultures.     

Geologic constraints on rain-fed Qocha reservoir agricultural infrastructure,northern lake Titicaca Basin,Peru

This paper reports new data on qocha ponds from the Rio Pucara–Azángaro interfluvial zone, northern Lake Titicaca Basin, Peru. Qocha are a little known form of Andean agriculture that developed around 800–500 B.C. and remain in use today. Prior estimates suggested that in the study area, there were more than 25,000 qocha. While most Andean sunken beds are excavated to reach groundwater, qocha are rain-fed ponds. How these rain-fed ponds functioned has been an open question, but one that is answered in part by research presented in this paper. We suggest that a thick impermeable stratum of clay that was possibly deposited by paleolake “Minchin” created a perched water table that makes rain-fed qocha reservoir agriculture possible. Field geology shows that within the study area, this stratum only exists under Terrace E. Based on this model, we hypothesized that persistently used qocha should only be found on Terrace E. To test this hypothesis we used remotely sensed data to inventory qocha and to determine their distribution by each terrace present. We identified 11,737 qocha. By area 93.77% and by count 94.33% of the qocha are located on Terrace E. These results strongly supported our hypothesis. This case study illustrates that the long term viability of this form of agriculture is made possible by a physical context that is beyond human control.     

Testing the accuracy of portable X-ray fluorescence to study Aztec and Colonial obsidian supply at Xaltocan,Mexico

This article demonstrates the accuracy of non-destructive portable X-ray fluorescence (pXRF) for the study of obsidian in central Mexico. Obsidian sources were identified for a sample of 103 artifacts from the site of Xaltocan, which spanned the rise and fall of the Aztec empire and the first centuries of Spanish colonial rule (AD 900–1700). Sources were assigned by comparing pXRF measurements with previously published source data and were verified using the standard techniques of laboratory XRF (lXRF) and instrumental neutron activation analysis (INAA). Additional tests of potentially confounding factors show that neither length of read time, presence of surface residue, nor incomplete detector coverage due to small artifact size compromised our ability to attribute sources to artifacts. Concave surfaces did decrease the accuracy of readings because of the greater distance between the artifact and the detector. Our results provide new insight into the stability of supply networks and markets well into the Colonial period as well as the homogenizing tendencies of the Aztec market system.     

Qu(e)erying Sex and Gender in Archaeology: a Critique of the “Third” and Other Sexual Categories

In this paper, I will recover the issue of the “third gender” in archaeological analysis in order to argue that the use of a “third,” despite what it may appear at first sight, does not challenge the logic inherent in gender and sexual binaries, that is, the use of universal, ahistorical, and stagnated categories. As an alternative, I will rely on Almudena Hernando’s genealogical work on gender and identity, as well as on Lucía Moragón-Martínez’s arguments regarding corporeality, to state that in “oral societies” (like prehistoric ones), body and person cannot be ontologically distinguished and, as a consequence, the anatomical features that we categorize as “sex” can neither be thought nor defined abstractly. I will further examine the implications of this claim in relation to the sex–gender fluidity that can be seen in those oral societies, formerly pigeonholed into the third gender category. In addition, I will analyze current literature developed by gender archaeologists in order to show the strengths and limitations of my proposal in relation to recent works on the topic.     

COMPLEMENTARITY BETWEEN LOCAL KNOWLEDGE AND INTERNATIONALIZATION IN REGIONAL TECHNOLOGICAL PROGRESS*

ABSTRACT Trade, foreign direct investment, and inter‐regional R&D spillovers facilitate competition, the spread of knowledge, and the adoption of more advanced technologies, which in turn hastens total factor productivity (TFP) growth. The spread of these efficiency gains from internationalization requires a sufficient local knowledge to enable them to be adapted to the domestic productive environment. Thus, higher local knowledge and internationalization will lead to TFP growth, and the greater the complementarity between variables the higher the TFP growth. We test the complementarity hypothesis using Spanish regional data over the period 1980–1995 in which both regional local knowledge and internationalization experienced a notable increase.     

Effect of organic and inorganic consolidation agents on Tlaltecuhtli monolith

A huge monolithic piece corresponding to the first years of the sixteenth century has been discovered in Mexico City. It represents the earth goddess Tlaltecuhtli. The preservation of such a magnificent piece is imperative. Therefore, the surface has to be characterized and the interaction of consolidants with the rock has to be understood.Some of the consolidation methods are impregnation of the mineral with nopal or silicic acid derivatives. In this work we compare the physico-chemical effects of organic and inorganic consolidants. Original and impregnated samples are characterized with a series of original techniques: X-ray diffraction, nuclear magnetic resonance, nitrogen adsorption and small angle X-ray scattering. Fractal dimension, specific surface area and pore size distribution clearly differentiated the samples. The organic materials, nopal gum or slobber, cover the mineral particles with a smooth layer. The KSE solutions react and lead to microporosity.     

Taking perspective of the stories we tell about transgender rights: The narrative policy framework

Our project uses the narrative policy framework (NPF) to explore narrative effects on attitudes about transgender rights. The framework focuses on the stories that are told about public policy. As opposed to conceptualizing communications as informational, NPF suggests that getting lost in the story is primary for attitude change. We also incorporate a perspective taking exercise to examine its effects on individual attitudes. Using an experiment on 1784 American adults, we found that individuals who received the inclusive transgender policy narrative by either watching or reading the narrative held views more supportive of transgender rights, with the effect greater for watching than reading. Those who experienced greater narrative transportation, being more lost in the story, reported more supportive attitudes. We further find that those with traits that lead them to become more imaginatively involved in stories occasionally are more greatly affected by watching policy narratives than those who are less imaginatively involved. However, perspective taking did not influence attitudes and weakened the treatment effects of the narratives. Our findings suggest stories can affect policy attitudes and beliefs, which may be conceptually distinct from traditional framing-based accounts and implies distinctive causal mechanisms that result in attitude change.
