This paper uses firm‐level data to examine how supply chain networks affected the recovery of firms from the Great East Japan Earthquake. Extensive supply chains can negatively affect recovery through higher vulnerability to network disruption and positively through support from trading partners, easier search for new partners, and general benefits of agglomeration. Our results indicate that networks with firms outside of the impacted area contributed to the earlier resumption of production, whereas networks within the region contributed to sales recovery in the medium term. The results suggest that the positive effects of supply chains typically exceed the negative effects.  相似文献

Alon Confino has issued a desideratum to other historians that they should bring questions and insights from cultural history to bear on the study of the Holocaust. Taking the work of Saul Friedländer as his point of departure, Confino nonetheless sets out on a path different from Friedländer's. He turns away from the goal of “integrated history” and instead seeks to investigate the realm of German culture, understood as encompassing much more than just Nazi ideology. By analyzing how the Holocaust has come to be perceived as unprecedented, as a rupture in human history, and furthermore by treating Jewish victims' sense of disbelief as an artifact of the past, one that has continued to inform unduly the historical understanding of the Holocaust up to the present day, historians will be able to account anew for what made the persecution and extermination of Jews imaginable and thus possible. With Confino's approach, a major historiographical question resurfaces, however: namely, what place an analysis of non‐Germans should occupy in the history of the Holocaust, and in particular what place should be accorded to Jewish voices? This essay argues that we cannot make sense of why Germans supported and carried out the Holocaust without also considering Jewish contemporaneous perspectives and imaginings.  相似文献

This paper studies the vertical and horizontal interactions between federal and regional governments in terms of public deficits. Recent studies commonly restraint budget slippages to the incentives created by the institutional arrangements within a country. Alternatively, we estimate here a fiscal reaction function for the Spanish regions over the period 1995–2010, paying special attention to the impact of the federal fiscal stance on regional fiscal imbalances. Our results indicate that higher public deficits for the central government encourage larger fiscal imbalances at the regional level. This vertical interaction is interpreted in the context of yardstick competition models. We also find a significant impact from fiscal decisions taken by governments at the same decision‐making tier in a specific region.  相似文献

This paper aims at disentangling the role played by different explanations on the urban wage premium along the wage distribution. We analyze the wage dynamics of migrants from lower to higher density areas in Italy, using quantile regressions and individual data. The results show that unskilled workers benefit more from a wage premium accruing over time, while skilled workers enjoy a wage premium when they migrate as well as a wage increase over time. Further, we find that for unskilled workers the wage growth over time is mainly due to human capital accumulation in line with the “learning” hypothesis, while for skilled workers the wage growth is mainly explained by the “coordination” hypothesis, i.e., cities enhance the probability of better matches between workers and firms.  相似文献

Summary. Evidence is discussed for the three theories on the origins of the Golden Fleece legend. That the epithet 'golden'referred to fine wool, because of its value, is thought to be not incompatible with the view that fleeces were used to collect gold particles from streams. That the fleece was yellow is unlikely since such discoloration is a wool fault, but it is just possible that 'golden' might refer to genetically 'tan' fibres.  相似文献

Ceramic vessels and associated vitreous debris, excavated at Coppergate, York, UK, have been interpreted as the remains of Roman glass‐making from the raw materials. This paper reports the results of analysis of this assemblage by XRF, ICPS, XRD, SEM– EDAX and thin‐section petrography. These findings suggest that some ceramic vessels, used as crucibles, have been subjected to temperatures up to 1200°C, well above the firing temperatures of the local domestic assemblage from which they were selected. Analysis of quartz‐rich debris, intimately mixed with glass in some samples and in others interleaved with glassy phases, indicates partially reacted glass‐making raw materials, with α‐quartz, tridymite and cristoballite phases represented. This could represent evidence either of a failed attempt to frit the raw materials, or a batch that had not fully fused. Variability in the composition of glass at the site is viewed in the light of glass‐making technology, and possible interpretations concerning this episode are discussed in the light of the archaeological evidence.  相似文献

DO FLOODS HAVE PERMANENT EFFECTS? EVIDENCE FROM THE NETHERLANDS   总被引:1,自引:0,他引:1  
This study investigates the short‐ and long‐run impact on population dynamics of the major flood in the Netherlands in 1953. A dynamic difference‐in‐differences analysis reveals that the flood had an immediate negative impact on population growth, but limited long‐term effects. In contrast, the resulting flood protection program (Deltaworks), had a persisting positive effect on population growth. As a result, there has been an increase in population in flood‐prone areas. Our results suggest a moral hazard effect of flood mitigation leading to more people locating in flood‐prone areas, increasing potential disaster costs.  相似文献

The article considers the story of the Norwegian sports strike during the Second World War. What kind of resistance does the story reveal? What was the effect of a boycott of leisure activities like sports? The Norwegian sports organizations, unlike other international sports organizations, came to see themselves as part of the resistance movement against the Nazi regime during the German occupation from 1940 to 1945, using non-violent, civil disobedience as their weapon. Unprecedented historically and internationally, this meant that Norwegian sportsmen and women, for four and a half years, stopped participating in any way in sport. The boycott comprised sportsmen and spectators, regardless of whether the contestants were friends or foes, Allies or Nazis, Norwegians or German. Based upon previous and recent research the article contends that the sports strike can be considered an effective act of civil disobedience. It demonstrated in a visible way that civil resistance was possible, while the German and Nazi authorities sought to promote sports as a means of creating an impression of normality. Finally, the story of the sports strike can be read as a tale of the limitations of totalitarian regimes.  相似文献

The major hazard posed by earthquakes is often thought to be due to moderate to large magnitude events. However, there have been many cases where earthquakes of moderate and even small magnitude have caused very significant destruction when they have coincided with population centres. Even though the area of intense ground shaking caused by such events is generally small, the epicentral motions can be severe enough to cause damage even in well-engineered structures. Two issues are addressed here, the first being the identification of the minimum earthquake magnitude likely to cause damage to engineered structures and the limits of the near-field for small-to-moderate magnitude earthquakes. The second issue addressed is whether features of near-field ground motions such as directivity, which can significantly enhance the destructive potential, occur in small-to-moderate magnitude events. The accelerograms from the 1986 San Salvador (El Salvador) earthquake indicate that it may be unconservative to assume that near-field directivity effects only need to be considered for earthquakes of moment magnitude M 6.5 and greater.  相似文献

In 2006–2007, the expedition from Peter the Great Museum of Anthropology and Ethnography, St. Petersburg excavated 52 inhumation burials at a 13th-14th- century cemetery in Kylalahti Kalmistomäki, Karelia. The burial goods are unusual for Karelia, eastern Finland, or other parts of northwestern Russia. The skeletal remains provide the first chance of assessing the biological affinities of the medieval “Korela.” The group displays a trait combination similar to that observed in modern Karelians and opposing them to other recent Eurasian populations. The same combination is observed in Mesolithic and Neolithic crania from the Eastern Baltic. The Kylalahti Kalmistomäki series supports the hypothesis stating that features of the early inhabitants of Europe have survived in certain populations of northwestern Eurasia up to the present time.  相似文献

Most research on the art market focuses on the high end, composed of auction houses and a few well‐known dealers. In this paper, we use a new database to examine the industry structure and location patterns of the New York art market, which consists largely of small, independent, relatively unknown galleries. We find that Manhattan galleries are highly spatially concentrated, and that clustering reflects both agglomeration economies and preferences over location‐specific amenities. New galleries are more likely to open in neighborhoods with existing gallery clusters, and proximity to other galleries increases establishment lifespan. New galleries also locate in neighborhoods with high population density and more affluent households, consistent with location models of luxury retail. The results are not consistent with the hypothesis that galleries locate in cheap, “bohemian” neighborhoods.  相似文献

Using adjusted 2000 population census data, this paper conducts projections of China's population up to 2050. Three fertility and four mortality scenarios yield 12 sets of results. Even though fertility is below replacement, China's population will continue growing for many years. One of the notable trends is the rapid ageing of the population. By the end of 2050, one-fifth to one-third of China's population will be aged 65 and over. The demographic dividend is expected to continue in next 10 to 20 years depending on future fertility which, in turn, is determined by changes in China's one-child policy. The Chinese government should be aware of all possible situations of population change, and particularly population ageing in the first half of the century, and be well prepared for all possible challenges that may arise.  相似文献

On March 31, 2014, Phentok, the first woman mountaineer in the world to reach the summit of Mt. Qomolangma from the north side, passed away because of complications from diabetes, aged 75. From her humble upbringing as a serf to the first Chinese woman on Mt. Qomolangma, she left behind an uplifting life story.  相似文献

The term “post-truth” is a capacious trope that collects threats to the stability of shared knowledge on many fronts—digitally spread disinformation, ignorance and resistance to science, unabashed lies in the public sphere, mythologizing by resurgent nationalist forces, and so on. History is particularly vulnerable to this array. Post-truth threats to serious history produced to professional standards for research and reasoning by historians free of coercion, intimidation, or pressures for co-optation are too blatant to need explanation. Avenues of response to the politicizing of history have been protests by public intellectuals and academics and a growing scholarly literature recording the imposition of memory laws by the police powers of numerous states. Attacks on empirical history, and the academic freedom required to sustain it, provoke clear responses, but the situation of historical theory is more problematic. Historical theory is a superstructure of analysis that presupposes the free production of history that invites and justifies the cultural work of theorizing. Reading Karen S. Feldman's Arts of Connection: Poetry, History, Epochality, an erudite, philosophical contribution to historical theory advancing a severe critique of history's fundamental powers of representation against a widening background of nationalist state-sponsored policing of history, produced an acute cognitive dissonance in this reviewer. In this essay, I frankly acknowledge this dissonant experience and lay out some of the most egregious causes of it in history distorted and undermined to nationalist ends in Russia, Poland, Hungary, and beyond. I pose the question of whether the intellectual work of theorizing history can continue with any confidence when the ground on which theory stands is being eroded and distorted.  相似文献

In the Slingram electromagnetic method the appropriate coil orientation must be chosen. Until now, the choice of this parameter has not been discussed but as it influences the shape of the anomalies and their magnitude, it is important to try to define the best possible arrangement. Theoretical studies of the 1D layered model, the response of a dipole and the response of a 3D body are used to define the best arrangement. The perpendicular configuration with a vertical moment transmitter gives better results in most cases and the building of an apparatus with this coil arrangement should give very interesting results.  相似文献
