This article examines policy feedback via economic behavior in the mass public, with a focus on consumption behavior. Do public policies affect the consumption behavior of mass publics and subsequent policymaking processes and outcomes? If so, how? I introduce a policy feedback model of consumption behavior in the mass public. Within this model, I advance a theoretical argument on the consequences of targeted cash assistance policies (TCAPs) for consumer spending behavior and government provision of basic utilities in developing countries. Using a randomized field experiment in Mexico and pre–post analysis, I find that TCAPs boost consumer spending on private access to basic utilities in the short term and reduce government provision of basic utilities in the medium term. The study pushes policy feedback theorists to think beyond the arena of mass politics, and the findings have important implications for social policy and human development in developing countries.  相似文献

This article re‐examines Cumann na nGaedheal's approach to party organisation. Cumann na nGaedheal has been portrayed as a badly organised, ‘top‐down’ party that suffered electorally for its reluctance to match the structure and organisation of its main anti‐Treaty rival, Fianna Fáil. Moreover, the party has been caricatured as a conservative organisation with little affinity for the ideology of the Irish revolution. While recent studies have reappraised Cumann na nGaedheal's engagement with the revolutionary inheritance, while highlighting underappreciated aspects of the party's electoral innovations, its organisational structures require further scholarly attention. Closer scrutiny of Cumann na nGaedheal's organisational structures sheds further light on its fate as nationalist Ireland's first party of government and ultimately its demise as a distinct party in 1933.  相似文献

Elected leaders adopt “anticipatory feedback strategies” in designing public policies that generate support and forestall opposition. This contention is at the core of a social construction theory of feedback. Officials anticipate approval when policies allocate benefits to powerful groups socially constructed as deserving and allocate costs or punishment to groups viewed as undeserving, particularly if these groups lack political power. Designs for powerful groups that are widely viewed as unworthy provide mainly benefits in ways that are hidden from the general public who would not approve. For politically weak groups regarded as deserving, legislators generally design policies that provide promises, but not much in terms of material benefits. Often, deception will be used to protect or enhance this particular allocation pattern, including the reinforcement, perpetuation, or change in the social constructions along with the stereotypes, labels, stigma, and accompanying narratives. Using data from legislation introduced by the 2016 Arizona Legislature, we find that most policy is directed toward providing benefits to positively viewed target populations, as expected by the theory, and legislators employ deceptive feedback strategies that protect themselves. Feedback from the general public, which otherwise might be expected, may be precluded by the deceptive strategies being used.  相似文献

Here, we report the physico‐chemical characterization of wall paintings from the Petros and Paulos church in Ethiopia. This work represents the first technical study of paintings located in Ethiopia, rather than paintings in museum collections outside the country, using diverse analytical techniques. In situ examination with a portable X‐ray fluorescence spectrometer (pXRF) was followed by analysis of samples using optical microscopy (OM), scanning electron microscopy coupled with energy‐dispersive X‐ray spectroscopy (SEM/EDS), micro‐Raman spectroscopy (MRS), attenuated total reflection – Fourier transform infrared spectroscopy (ATR‐FT–IR), X‐ray powder diffraction (XRD) and pyrolysis gas chromatography – mass spectrometry (Py‐GC/MS). The paint stratigraphy, the compositions of the support material, the preparatory and painting layers were studied, as well as the morphology of the pigment particles. The results revealed the use of earth pigments and carbon black. The preparatory layer was uncommon; composed of dolomite, clay rich in clinochlore and sand, in contrast to the more common gypsum and calcite. The binder and the stratigraphic analyses suggested a distempera technique.  相似文献

Black drink is a native North American caffeinated tea produced from the leaves of Ilex vomitoria. The beverage was an important part of prehistoric Southeastern culture, as it was the only native source of caffeine in North America. The leaves of I. vomitoria were, therefore, a potentially valuable trade resource during the period. As such, the ability to identify archaeological black drink residues is useful to Southeastern archaeologists. In order to determine the plausibility of detecting I. vomitoria in residues, black drink was repeatedly produced in experimental unglazed pottery. The resulting potsherds were buried in several environmental contexts, recovered, and underwent absorbed pottery residue analysis. After two months of burial in three different soil types, plus a control stored in the freezer, caffeine was well-preserved in all sherds, suggesting that caffeine is a potentially useful biomarker for the detection of black drink.  相似文献

The partially mummified remains of a high-status female (ca. 1700 BP, Thessaloniki, Greece) were found inside a Roman-type marble sarcophagus containing a lead coffin. The individual was positioned on a wooden pallet, wrapped in bandages, and covered with a gold-embroidered purple silk cloth. Besides the clothes, remnants of soft tissue as well as the individual's original hair style and eyebrows were exceptionally well preserved. In addition to the macroscopic examination, microscopic and biochemical analyses were undertaken. Scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) analysis, and gas chromatography/mass spectrometry (GC/MS) were applied to examine the tissue preservation and probable mechanisms of mummification. The presence of chemical components, such as sesquiterpenes, triterpenoids, and diterpenoids, originating from coniferous and pistacia resins, myrrh, and other spices, verify ancient information on preparation methods of the dead in Greek and Roman times. These chemical components are thought to have played a prominent role in the mummification mechanism in this particular case. The potential effect of the lead coffin in the mummification process was also examined. Energy-dispersive X-ray analysis failed to detect lead penetration into the tissues, suggesting that the coffin played a limited role in the preservation of soft tissue.  相似文献

The time of appearance of a persistent and demographically-viable hunter-gatherer population in late Pleistocene southern South America must be determined by evaluating evidence from as large as possible a sample of candidate archaeological sites in the region. We co-ordinated the AMS dating of multiple bone and charcoal samples from previously-excavated strata at the following sites: Arroyo Seco 2, Paso Otero 5, Piedra Museo, and Cueva Tres Tetas (all in Argentina), and Cueva del Lago Sofia 1 and Tres Arroyos (both in Chile). With one possible exception, we did not obtain new results to confirm earlier observations of pre-Clovis-age cultural activity at any of the sites considered in this study. The possible exception, Arroyo Seco 2, is considered in detail elsewhere [Politis G., Gutierrez M.A., Scabuzzo, C. (Eds), in press. Estado actual de las Investigaciones en el sitio 2 de Arroyo Seco (región pampeana, Argentina). Serie Monográfica INCUAPA 5. Olavarría]. However, our results for the samples which were the most preferred indicators of cultural events (hearth charcoal and cut-marked bone) confirm that people were in the southern cone of South America at or soon after 11,000 BP (13,000 cal BP). Considered alongside recent age estimates for the Clovis culture in North America, these results imply the contemporaneous emergence of a consistent and archaeologically-robust human occupation signal at widely-separated locations across the Western Hemisphere. Such findings suggest that Palaeoindian demic expansion may have involved more than one terminal Pleistocene dispersal episode.  相似文献

Flake debris — the by-product of lithic reduction — is abundant, not subject to uncontrolled collection, and sometimes culturally diagnostic. Its greatest virtue, however, is in registering the kinds and amounts of toolmaking and tool-using behavior that curated tools themselves may not. Most debris studies emphasize formal dimensions, yet even the best approaches assume rather than demonstrate a relationship between behavior and formal variation. Moreover, the diversity of formal typologies hinders interassemblage comparison. Progress in debris analysis has two prerequisites: (1) a minimum attribute set for individual flakes and (2) the combination of formal and continuous approaches to variation. Preliminary study suggests that Ahler's mass-analysis model and log skew Laplace functions hold particular promise for behavioral interpretation from debris assemblages.  相似文献
