Combining empirical evidence with Amartya Sen's concept of capabilities, this article argues that the digital divide is not merely a problem of access to ICTs. It is part of a larger developmental problem in which vast sections of the world's population are deprived of the capabilities to use ICTs, acquire information and convert information into useful knowledge. Fieldwork research including sample surveys conducted in rural locations in Kerala and Andhra Pradesh in India shows that these capabilities can only be created through large‐scale complementary interventions in economic and social development.  相似文献

The High Court of Australia’s decision in Monis v The Queen and Droudis v The Queen concerned whether Monis and Droudis’s use of the postal service to send offensive letters warranted the constitutional protection of the implied freedom of political communication. The outcome was a split decision: the three men judges found for Monis and Droudis, and the three women judges against. We argue that this decision was significant because it draws attention to the law’s key role in framing political understandings of the nature of and demarcation between public and private spheres. The Court’s interpretations concerning how we should understand and apply the foundational relationships binding the state, the individual, and the public and private spheres in the twenty-first century highlights the gendered complexities of the politics shaping those relationships. It also highlights the gendered privileging of what sort of speech should be exempted from the law’s immediate purview, and in so doing, further reveals the masculinism upon which Australia’s constitutional framework rests.  相似文献

The issue of reallocating population figures from a set of geographical units onto another set of units has received a great deal of attention in the literature. Every other day, a new algorithm is proposed, claiming that it outperforms competitor procedures. Unfortunately, when the new (usually more complex) methods are applied to a new data set, the improvements attained are sometimes just marginal. The relationship cost‐effectiveness of the solutions is case‐dependent. The majority of studies have focused on large areas with heterogeneous population density distributions. The general conclusion is that as a rule more sophisticated methods are worth the effort. It could be argued, however, that when we work with a variable that varies gradually in relatively homogeneous small units, simple areal weighting methods could be sufficient and that ancillary variables would produce marginal improvements. For the case of reallocating census data, our study shows that, even under the above conditions, the most sophisticated approaches clearly yield the better results. After testing fourteen methods in Barcelona (Spain), the best results are attained using as ancillary variable the total dwelling area in each residential building. Our study shows the 3‐D methods as generating the better outcomes followed by multiclass 2‐D procedures, binary 2‐D approaches and areal weighting and 1‐D algorithms. The point‐based interpolation procedures are by far the ones producing the worst estimates.  相似文献

This report presents the results of using NASA/JPL airborne synthetic aperture radar data (AIRSAR) to detect ancient Maya settlements beneath jungle canopy in Guatemala. AIRSAR stands out from previous applications of radar remote sensing in the Maya lowlands because of its canopy-penetrating capabilities. The authors offer an overview of the AIRSAR technology, followed by a case study in which the AIRSAR data receive testing in the field. Reconnaissance in the region around the Maya site of El Zotz led to the discovery of two new sites, including the medium-sized settlement of La Avispa. AIRSAR also aided archaeologists in detecting zones of residential settlement around the site core of El Zotz. This research will serve as a guide for future applications of radar remote sensing in Maya archaeology.  相似文献

The article examines the interest in the United States for the construction of a trans-oceanic canal in Central America. In 1820, William Davis Robinson published a book, Memoirs of the Mexican Revolution, which contained an appendix discussing the practicability of building a trans-oceanic canal including detailed analysis of the potential routes for its construction. The appendix sparked a lively debate among American political and economic leaders. This debate would not abate until the enormity of the financial and engineering realities of the project coupled with the continuing political instability of Mexico, Greater Colombia, and the Republic of Central America dampened investor enthusiasm.  相似文献

This article presents three years of archaeological investigations at the minor Maya center of Bejucal, Guatemala. A complete site history is presented relying on data from artifact analysis, architectural study, epigraphy, and bioarchaeology, with a goal towards identifying the site's function within the broader El Zotz polity. The authors argue that Bejucal underwent significant transformation following its establishment as a sacred hilltop site during the Late Preclassic period (400 b.c.a.d. 250). The El Zotz royal family gradually appropriated the space, converting it into a royal country house and elite burial place. Bejucal's proximity to a large permanent water source suggests that the country house was situated within favorable hunting grounds. The research contributes to a broader discussion about the role of minor centers in regional settlement patterns, highlighting the benefit of textual data in making interpretations. The article also highlights the important role of salvage work in lowland Maya archaeology.  相似文献

The former Spanish Sahara is the last remaining colony in Africa. Most of the local people have been living in refugee camps in Algeria for the last 40 years and this situation has largely conditioned the archaeological research in the territory for a long time. In spite of the Saharawi Ministry of Culture in exile occasionally collaborating with European academic institutions for the study of its huge archaeological heritage, the training of local archaeologists or initiatives exclusively aimed at targeting the self-management of the Saharawi Archaeology are rarely carried out. This could be due to the difficulties in getting funds for long-term projects in this area, among other factors. However, today’s technological revolution has come to the desert including mobile telephones, televisions, computers and even an incipient Internet connection. At the same time, current digital technology has encouraged the development of new methods of documenting rock paintings, which might be appropriate and more accessible for the Saharawi technicians. This paper discusses the successful and failed aspects, as well as future perspectives, of a training course in rock art documentation intended for empowering local archaeologists who are living in very unfavourable circumstances.  相似文献
