Whilst the deadline for achieving the Millennium Development Goals (MDGs) looms large, the outcomes so far have been mixed. This article examines the policy logic that ‘good governance’ leads to poverty reduction, which has been adopted by international agencies in pursuit of the MDGs. This causal relationship is examined through an empirical panel‐data estimation using Worldwide Governance Indicators and the poverty headcount ratio in ninety‐eight countries. The empirical evidence does not support the hypothesis that good governance leads to poverty reduction. Good governance alleviates poverty only in middle‐income countries, not in least developed ones. These findings point to the necessity to devise policies that address poverty directly, rather than through indirect instruments, and highlight the urgent need to address structural inequality in developing countries. 相似文献

Archaeobotanical research over the past decades has revealed that bread wheat of a compact form, called “Ezo wheat” in Japan, was present in the Far East Asian region (Primorye in the Russian Far East, the Korean peninsula, and the Japanese archipelago) during the early stage of wheat cultivation. In response to the previous observations, carbonized wheat grains from the sites in the southern part of the Korean peninsula were measured and their sizes were compared across these sites and with other sites in East Asia. The examination indicates that grains dated over the period of AD 100–600 were considerably smaller than the modern specimens but were plumper than the previously reported Ezo wheat. The new data sets suggest that wheat with plumper kernels was introduced to the region no later than the Three-Kingdoms period (ca. AD 300–668) and continued to be cultivated until the Joseon period (1392–1910). 相似文献

Except for about a half dozen papers, virtually all (co)authored by Griffith, the existing literature lacks much content about the interface between spatial optimization, a popular form of geographic analysis, and spatial autocorrelation, a fundamental property of georeferenced data. The popular p-median location-allocation problem highlights this situation: the empirical geographic distribution of demand virtually always exhibits positive spatial autocorrelation. This property of geospatial data offers additional overlooked information for solving such spatial optimization problems when it actually relates to their solutions. With a proof-of-concept outlook, this paper articulates connections between the well-known Majority Theorem of the 1-median minisum problem and local indices of spatial autocorrelation; the LISA statistics appear to be the more useful of these later statistics because they better embrace negative spatial autocorrelation. The relationship articulation outlined here results in the positing of a new proposition labeled the egalitarian theorem. 相似文献

Machine learning (ML) is being applied in an increasing volume of geographical research. However, the aspects of spatial autocorrelation (SAC) in the residuals produced by ML models have been understudied compared to the benefit of ML, namely, reduction of prediction errors. In this study, we examined the relationship between predictive accuracy and the reduction in the residual SAC for 597 variables from 25 geographical socio-economic data sets using spatial and nonspatial cross-validation of three ML algorithms such as random forests, support vector machine, and artificial neural network (ANN) to provide an extensive empirical diagnosis—but not a definitive theory—of the relationship between SAC and ML. Our results highlighted that the ML algorithms with tuned hyperparameters yielded marginal predictive accuracy gains and the minimal decreases in residual SAC. ANN revealed lower accuracy and higher reduction in the residual SAC than others. This implies ML algorithms in geographical research in socio-economic domains would not always result in higher prediction accuracy. We suggest that ML in geographical research should be cautiously employed when the main objective is related to the residual SAC. We also showed that spatial cross-validation neither improves predictive accuracy substantially nor reduce the residual SAC effectively. 相似文献

Recent studies have shown that the site coefficients obtained from site response analyses of Korean soil sites are significantly different from those specified in the current Korean seismic code, especially in the short-period portion of site response. This difference is mainly attributed to the shallow bedrock conditions (bedrock depth usually less than 30 m) in Korea. This study proposes a new site classification system and site coefficients for shallow bedrock sites based on site response analyses of more than 300 sites. The proposed site classification scheme and site coefficients proposed in this study are an improvement over the current seismic code and previous studies. 相似文献

Globalisation, or segyehwa1 in Korean, has recently been the central theme in discussions of South Korean political economy, particularly in strategic policy-making discourses since the outbreak of the Asian financial crisis, which was triggered by the collapse of the Thai baht in 1997. The serious nature of the South Korean currency meltdown in 1997 resulted at first glance in a striking transition in the South Korean political economy from state-driven market and industrial policies, and a strong nationalist policy towards foreign capital (inflow of foreign direct investment), to a neo-liberal policy of globalisation. This article critically examines the paradoxical nature of Korea's globalisation efforts under three political regimes (February 1993–February 2008), as a response to new economic conditions embedded in the nature of developmental capitalism. The paper argues that South Korea's globalisation effort over the period has been highly pragmatic and selective in policy and regulations but has resisted embracing the principles of market-driven globalisation. South Korea's globalisation drive or segyehwa therefore appears only a temporary phenomenon rather than a carefully structured strategic policy. 相似文献

Physical, structural and chemical analyses were made on slag remains obtained from three sites in Iron Age arctic Norway. Scanning electron microscopy and x‐ray microanalysis were employed to confirm that the slag can only be a result of iron production. Although a distinction between slag produced by smithing and smelting proved difficult, consideration of the processes and the resources available support the assumption that both were practiced at the sites. The results provide firm evidence of iron production in the region of Norway north of the 69th parallel, by at least the sixth century AD. 相似文献

In this paper our primary concern is with a spatial model of competing firms in a regional industry. The firms are producing for an extraregional market and are located so as to gain exclusive access to a dispersed raw-material input. After outlining the form of the industry long-run average cost curve, we specify the equilibrium outcome, both for the individual firm and the regional industry. We demonstrate that the industry long-run supply curve does not coincide with the industry long-run average cost curve. We further show that the outcome in the spatial model results from the separation of firms, each firm having its own domain, part or all of which becomes its supply area. 相似文献
