We exploit the GEOSTAT 2011 population grid to document that Spain presents the lowest density of settlements among European countries. Only a small fraction of the Spanish territory is inhabited, particularly in its southern half, which goes hand in hand with a high degree of population concentration. We uncover through standard regression analysis and spatial regression discontinuity that this anomaly cannot be accounted for by adverse geographic and climatic conditions. The second part of the paper takes a historical perspective on Spain's settlement patterns by showing that the spatial distribution of the population has been very persistent in the last two centuries, and that the abnormally low density of settlements with respect to European neighbors was already visible in the 19th century, which indicates that this phenomenon has not emerged recently as a consequence of the transformations associated with industrialization and tertiarization. Using data on ancient sites, we find that Spain did not feature scarcity of settlements in comparison to other countries in pre-medieval times, suggesting that its current anomalous settlement pattern has not always existed and is therefore not intrinsic to its geography.

The 19Th Century

In this paper, we analyse features of the grammatical descriptions in Manchu grammar books from the Qing Dynasty. Manchu grammar books exemplify how Chinese scholars gave Chinese names to grammatical concepts in Manchu such as case, conjugation, and derivation which exist in agglutinating languages but not in isolating languages. A thorough examination reveals that Chinese scholarly understanding of Manchu grammar at the time had attained a high degree of sophistication. We conclude that the reason they did not apply modern grammatical concepts until the end of the 19th century was not a lack of ability but because the object of their grammatical descriptions was Chinese, a typical isolating language.

The City

Tent encampments have become an especially common form of homelessness in West Coast cities like Oakland, California, where the number of people living in tent encampments increased by 130 percent between 2017 and 2019. Living in tent encampments provides residents both benefits and risks, depending on the encampments’ location, size, and stability. Using data from Google Street Views, I document the growth and spatial dynamics of tent encampments in west and central Oakland over the last decade. The number and size of tent encampments rapidly increased between 2014 and 2019, varying widely in their stability. City interventions like the city’s outdoor transitional housing sites displaced several large tent encampments. Combined with overall tent encampment growth, these displacements dispersed the encampments throughout nearby neighborhoods and other parts of the city.

American politics today is driven largely by deep divisions between Democrats and Republicans. That said, there are many people who view the opposition in an overwhelmingly negative light – but who simultaneously possess a mix of positive and negative feelings toward their own party. This paper is a response to prior research (e.g., Lavine, Johnson, and Steenbergen 2012) indicating that such ambivalence increases the probability that voters will engage in "deliberative" (or "effortful") rather than "heuristic" thinking when responding to the choices presented to them in political campaigns. We extend the logic of this argument to a hypothetical race for Congress, using data from a survey experiment to determine whether a high degree of ambivalence toward one's party makes voters more responsive to a negative attack against the candidate of that party. In fact, we find little evidence that partisan ambivalence promotes a deliberative response to negative campaign ads.

The Relationship

The complexity of COVID-19 and variations in control measures and containment efforts in different countries have caused difficulties in the prediction and modeling of the COVID-19 pandemic. We attempted to predict the scale of the latter half of the pandemic based on real data using the ratio between the early and latter halves from countries where the pandemic is largely over. We collected daily pandemic data from China, South Korea, and Switzerland and subtracted the ratio of pandemic days before and after the disease apex day of COVID-19. We obtained the ratio of pandemic data and created multiple regression models for the relationship between before and after the apex day. We then tested our models using data from the first wave of the disease from 14 countries in Europe and the US. We then tested the models using data from these countries from the entire pandemic up to March 30, 2021. Results indicate that the actual number of cases from these countries during the first wave mostly fall in the predicted ranges of liniar regression, excepting Spain and Russia. Similarly, the actual deaths in these countries mostly fall into the range of predicted data. Using the accumulated data up to the day of apex and total accumulated data up to March 30, 2021, the data of case numbers in these countries are falling into the range of predicted data, except for data from Brazil. The actual number of deaths in all the countries are at or below the predicted data. In conclusion, a linear regression model built with real data from countries or regions from early pandemics can predict pandemic scales of the countries where the pandemics occur late. Such a prediction with a high degree of accuracy provides valuable information for governments and the public.

AbstractThe net mass balance (1986/87–1989/90) was calculated for a small cirque glacier in the Italian Alps (Ghiacciaio della Sforzellina, 0.42 k m2, Ortles–Cevedale Group). Four annual mass balances are presented here. All four balances were negative (mean value: –0.90 m year−1), with a maximum deficit of –1.16 m year−1 in 1989–90. The climatic conditions (which are analyzed using data from the S. Caterina Valfurva Station) consisted of a succession of cold, dry winters with little snowfall. Frontal-variation data available since 1925 show a constant retreat until 1966, followed by a brief advance period which has already terminated.

Abstract BackgroundThis study is an attempt to demonstrate the potential for classifying GP practices in Czechia along an urban versus rural dimension and to compare the structure of areas thus defined with the OECD territorial typology. The aim is to ascertain whether a general approach to distinguishing regions is transferrable and could be used to define GP practices in Czechia. MethodsIn this study two variants are considered using data supplied to the authors by the largest health insurance company in Czechia, using geographical information systems. The results were then compared with the OECD regional typology, in which areas are classified as predominantly urban, intermediate, and predominantly rural. ResultsThe two GP practice typologies were then found to correspond closely to the OECD typology, but the most recent variant is more suitable. A high degree of similarity was evident in the categorisation of urban regions, and therefore practices, and slightly less so in the rural type areas. The most problematic aspect is defining the intermediate type, which has its own peculiarities and has to be considered within the wider context. ConclusionsDespite some structural differences, we can state that the main thinking behind the OECD typology is transferrable and can be used to determine urban versus rural healthcare providers, especially primary care ones. Nonetheless, the results point to further research avenues, especially on how to best to define the intermediate category so greater accuracy can be achieved in determining the resulting urban versus rural polarity.
