Continuous‐Time Modeling with Spatial Dependence

(Spatial) panel data are routinely modeled in discrete time (DT). However, compelling arguments exist for continuous‐time (CT) modeling of (spatial) panel data. Particularly, most social processes evolve in CT, so that statistical analysis in DT is an oversimplification, gives an incomplete representation of reality, and may lead to misinterpretation of estimation results. The most compelling reason for a CT approach is that, in contrast to DT modeling, it allows adequate modeling of dynamic adjustment processes. This article introduces spatial dependence in a CT modeling framework. We propose a nonlinear structural equation model (SEM) with latent variables for estimation of the exact discrete model (EDM), which links CT model parameters to DT observations. The use of a SEM with latent variables enables a specification that accounts for measurement errors in the variables, leading to a reduction of attenuation bias (i.e., disattenuation). The SEM‐CT model with spatial dependence developed here is the first dynamic SEM with spatial dependence. A simple regional labor market model for Germany, comprising changes in unemployment and population as endogenous state variables, and changes in regional average wages and in the structure of the manufacturing sector as exogenous input variables, illustrates this spatial econometric SEM‐CT framework. El modelamiento de datos panel espaciales se realiza habitualmente utilizando una conceptualización del tiempo discreto (TD). Sin embargo, existen argumentos de peso para conceptualizar el tiempo de manera continua (TC). En concreto, la mayoría de procesos sociales se desarrolla en TC, por lo que el análisis estadístico en DT trae como consecuencia una simplificación excesiva de los procesos, da una representación incompleta de la realidad, y puede conducir a una interpretación errónea de los resultados de la estimación. La razón más convincente para el uso de un enfoque CT es que a diferencia de modelos DT, una conceptualización CT permite el modelado adecuado de los procesos de ajuste dinámico (dynamic adjustment). Este artículo incorpora la dependencia espacial en un marco de modelamiento con CT. Los autores proponen un modelo de ecuaciones estructurales no lineal (nonlinear structural equation model ‐SEM) con variables latentes para la estimación del modelo discreto exacto (exact discrete model‐EDM), que vincula los parámetros del modelo CT a las observaciones de DT. El uso de un SEM con variables latentes permite una especificación que da cuenta de los errores de medición en las variables, dando lugar a una reducción del sesgo de atenuación (es decir, “desatenuacion”). El modelo SEM‐CT con dependencia espacial desarrollado en el presente estudio es el primer SEM dinámico con dependencia espacial. Para ilustrar el marco conceptual SEM‐CT los autores presentan un modelo simple del mercado laboral regional de Alemania. El modelo está compuesto por los cambios en el desempleo y la población como variables endógenas de estado, y los cambios en los salarios regionales promedio y en la estructura del sector manufacturero como variables de entrada exógenas. （空间）面板数据通常基于离散时间（DT）进行建模。然而更令人信服的观点是基于连续时间（CT）进行（空间）面板数据建模。特别是多数社会过程均在连续时间中演化,基于离散时间的统计分析可能过度简化,使得对现实状况的表达不完备,并可能导致对估计结果的错误解释。相比于离散时间（DT）建模,连续时间（CT）建模最具说服力的原因在于在建模过程中允许足够多的动态调整。本文介绍了CT模型框架中的空间依赖性。把CT模型参数链接到DT观察值中,我们提出了用于估计精确离散模型（EDM）的包含潜变量的非线性结构方程模型（SEM）。包含潜在变量的SEM提供了变量测量误差的计算方案,使得衰减偏差（如反衰减性）减小。本文了提出的空间相关SEM‐CT模型是第一个动态空间相关的SEM模型,并以德国一个简单的区域劳动力市场模型为例,以失业和人口构成变化为内生状态变量,以区域平均工资和制造业结构部门变化为外生输入变量,阐述了该空间计量SEM‐ CT模型的框架。     

Die Lektorate für schwedische Sprache in Deutschland im Kontext der auswärtigen Kulturpolitik 1917–1930

The Lectureships for Swedish in Germany in the Context of Cultural Diplomacy 1917–1930. During the Weimar Republic a significant number of lectureships for Swedish was established at German universities. This paper attempts to explain this development through an analysis of the political and academic context of these establishments. Focussing on the actors involved the lectureships are linked to the emerging interest of the German state for public diplomacy emerging after World War I and the following reactions of German academia. The paper also treats the importance of the main Swedish actor, namely the association for the preservance of Swedishness abroad for the establishments of the lectureships. At the end the different actors working for Swedish lectureships in Germany are placed in a broader European context and questions concerning the relationship between universities and cultural diplomacy are raised and answered.     

The Ritual Year of Athena: The Agricultural Cycle of the Olive,Girls' Rites of Passage,and Official Ideology

Through the ritual year of ancient Athens, many festivals were dedicated to Athena. The Panathenaia was the most important festival. It has been regarded as a political festival, but the importance of agriculture is also illustrated through the offerings and rituals carried out during this main festival dedicated to the Goddess of the olive crop. All Athena's festivals were related to the olive, the third main crop of the Athenians, and protected by her, as her festivals were celebrated in the crucial period for the olive crop, from the flowering of the olive tree, growing period of the fruit, until the gathering in winter. The summer festivals, particularly, may be related to the importance of securing the dew for the growing fruit. Many rituals during the festivals reflect the daily activities of women, several rituals are also important to the rite of passage undergone by girls at puberty to prepare them for marriage.     

Consuming campus: geographies of encounter at a British university

In this paper, we extend recent discussions on the geographies of encounter to examine how students and staff narrate their experiences of cross-cultural contact on a British university campus. In theory, the campus environment offers opportunities for more intense and prolonged forms of contact than the ephemeral micro-scale forms of interaction that have dominated much of the literature on encounters. In practice, however, our interviews suggest that many respondents tend to self-segregate, or in some instances are prevented from mixing with ‘others’ through institutional arrangements. As we also illustrate, the pressures posed by commercial forces on campus orientate certain students towards lifestyle choices and expectations which exclude others.     

Ammonite dating of latest Cretaceous mosasaurid reptiles (Squamata,Mosasauroidea) from Jordan—preliminary observations

Jagt, J.W.M., Jagt-Yazykova, E.A., Kaddumi, H.F. & Lindgren, J., April 2017. Ammonite dating of latest Cretaceous mosasaurid reptiles (Squamata, Mosasauroidea) from Jordan—preliminary observations. Alcheringa 42, 587-596. ISSN 0311-5518

Newly collected ammonoid material from the uppermost Cretaceous portion of the Muwaqqar Chalk Marl Formation exposed some 30 km southeast of the Qasr Al’Harrana area (east-central Jordan) includes medium-sized baculitids (Baculites ovatus auctorum, non Say), the sphenodiscid Libycoceras acutodorsatus (Noetling) and the pachydiscids Menuites fresvillensis (Seunes) and Pachydiscus (Pachydiscus) dossantosi (Maury). Of the two last named taxa, the former is a good marker species for the upper Maastrichtian, with records from Europe, central Chile, South India, Baluchistan (Pakistan), Australia, Madagascar and South Africa. The latter is known from the United Arab Emirates/Oman border area, from strata of (late) early to early late Maastrichtian age, as well as from more poorly constrained Maastrichtian levels in Brazil and Nigeria. A comparison with ammonoid assemblages from the Maastrichtian type area (southeast Netherlands/northeast Belgium) suggests correlation of the Muwaqqar Chalk Marl Formation with the middle/upper Maastricht Formation (Emael and Nekum members, ca 66.5–66.1 Ma) and the upper part of the coeval Kunrade Formation. However, associated ‘tegulated’ inoceramids of the Tenuipteria argentea group from the Muwaqqar Chalk Marl Formation favour equivalence with a higher level of the Maastrichtian type area, i.e., the Meerssen Member. From the upper Maastricht Formation and the equivalent upper part of the Kunrade Formation, the following mosasaur genera are currently known: Mosasaurus, Prognathodon, Plioplatecarpus and Carinodens. Interestingly, coeval strata of the Muwaqqar Chalk Marl Formation in east-central Jordan have yielded remains of a largely comparable suite comprising Prognathodon, Mosasaurus, Carinodens and an unnamed, highly derived plioplatecarpine.

Positioning in the Cold War – Swedish and Danish History Textbooks and the Totalitarianism Doctrine. Historical Cultures in Comparison

The Nordic countries Sweden and Denmark have a long and intertwined history. The Second World War, though, formed different experiences in the two countries that led to diverging paths in the Cold War. Denmark became a member of North Atlantic Treaty Organization, while Sweden stayed non-aligned. Thus, it can be assumed that Denmark was more likely to adopt Western foreign policies and doctrines than Sweden. Or was it? On a programmatic political level this may have been the case, but what about cultural perceptions developed in Swedish and Danish ‘minds of men’? Is there a tension between les évenéments and les longues durées?

The underlying assumption in this article is that there is a contradiction and a tension between the programmatic political level and historically-inherited enemy images, and that this tension may be studied through the concept of totalitarianism and its position in the historical cultures of Sweden and Denmark in the post-war era. The totalitarianism doctrine was one of the main ideological weapons during the Cold War, serving as a basis for the Truman doctrine. It implies that Nazism and Soviet communism shared common features and may be subsumed under the same label. But would a Dane find it reasonable to view the Red Army, which belonged to the Allies which liberated his or her country, as of ‘the same kind’ as the German occupants? And would it make sense to a Swede to stay neutral to Soviet Russia, the historical enemy? The one who for a Swede is ‘the other’ might for a Dane appear as a historical ally.

The role of Finland in the Swedish national and war economies during Sweden's period as a great power

The primary goal of this article is to present anti-Semitism as the underlying reason for the rejection of Israel-Jakob Schur's PhD dissertation at the University of Helsinki and at Åbo Akademi University in the late 1930s. The article analyzes the different stages of the processes and the ideological background and motives underpinning the rejections. Schur's antagonists were right-wing professors, some of whom sympathized with National Socialism and/or maintained contacts with eminent German anti-Semitic ideologues. The article analyzes the rhetoric of the written statements, which contain ideas of Christian anti-Semitism as well as other anti-Jewish stances. Moreover, the article demonstrates that Schur was regarded as an alien element in the Finnish academe, and the topic of his research – circumcision – was considered non-national from the perspective of Finnish science.
