冷战后日本国家战略的"普通化"与中日关系

本文将冷战后日本国家战略的演变明确定义为“普通化”即成为“普通国家”的进程,探讨这种变化与中日关系发展的内在联系,提出“普通国家间关系”应该成为21世纪中日关系的发展方向,并对形成未来双边关系机制的必要性做了相应阐述,认为这一分析框架是从国家战略层面把握中日关系发展的现实需要。     

The Numerical Basis of Roman Camps

Roman camps are based on rectangles with sides in whole number ratios and their areas are proportional to the size of the force encamped. The data given by Polybius and Hyginus suggests the area was surveyed in actus and indicates that it was calculated by simply adding up the space required by each unit from a standard allocation and then increasing that sum by a certain factor to allow for roads and other quarters. This gave the area within the intervallum , which was then added to define the inner face of the rampart. The paradigm can be simplified to the rule that two actus quadrati were allowed per cohort, with a turma counting as 1/8th cohort. The intervallum width was 1/8th the sq. root of the area it enclosed. Permanent forts also seem to have been laid out with the actus of the unit of measurement. The paradigm enabled use of a computer spreadsheet to investigate the possible composition of the forces associated with particular camps. This suggested that in the Mons Graupius campaign Agricola had two legions and built the 63-acre camps in NE Scotland.     

方志资料性浅议

方志是资料性著述 ,这是近年来关于方志本质的一种通行说法。在这一概念引导下 ,不少人认为方志的本质特征就是资料性。方志是否是资料 ,或者是否是资料性著述 ,资料性是否是方志的本质特征 ,目前似乎还有讨论的必要。因为 :第一 ,方志是资料还是著述 ,关系到方志体裁、内容及学术规范等一系列问题的确定 ;第二 ,这关系到方志在社会科学中的定位 ;第三 ,这种定位是否准确又关系到方志及方志学在新的历史条件下的发展方向。本文不赞成方志是资料或资料性著述 ,而认为志书是建立在丰富资料基础上的著述。     

Geometric Mosaic Pavements of Yasileh in Jordan

Abstract

The site of Yasileh in northern Jordan has two churches from the Byzantine period. In the church on the western bank of the Wadi Yasileh, dated to the middle of the 5th or the beginning of the 6th century AD, we uncovered one of the most impressive and best preserved mosaic pavements with geometric patterns in the Near East. In this paper, the writers attempt to show that the Yasileh mosaicists were true masters of their profession. They combined motifs that enjoyed a long popularity from the early and through the middle Roman period, with new designs appearing here for the first time, as far as is known. An attempt is made to trace the history and survival of several geometric patterns from the mosaic in the Western Church at Yasileh by comparison with the same patterns found elsewhere in the Levant. The significance of the non-figurative character of this mosaic and those of other church floors in Lebanon and Syria of a similar date is also considered.     

Evidence of Geometric Operators used to Shape Ancient Hulls

In some shipwrecks we can recognize factors such as units of measurement, use of segments and arcs, and repetition of shapes, which may have been rationalised during the transition from craft shipbuilding to a formal design process. This is an a posteriori assessment, as we do not know how hull‐shapes were planned and controlled in Antiquity. However the Cheops boat, and the Madrague de Giens, Anse des Laurons II, Fiumicino 4 and Yassi Ada II wrecks, display measurements and geometries suggesting rational approaches to hull‐moulding, with principles common to those of medieval and Renaissance shipbuilding and the traditional Mediterranean garbi. © 2012 The Author     

A Geometric Morphometric Study of Regional Craniofacial Variation in Mexico

Spanish speaking populations in the USA have long been categorised under the umbrella term ‘Hispanic’, which is a cultural construct. The term Hispanic ignores the unique ethnohistories and biological variation among Hispanic groups with various European, African and indigenous American influences. Considerable heterogeneity has been identified in pre‐contact America and has continued to influence the cultural and biological compositions of various regions today. The purpose of this research is to examine biological variation in Mexico, which was influenced by indigenous migration patterns and the Old World conquests of the Americans. Using multivariate statistics, this paper compares 16 three‐dimensional craniometric landmarks of samples from northern Central Mexico, northern Yucatan and western Mexico to examine the regional biological variation present in Mexico in both prehistoric and historic groups and also compares Mexican, Spanish and African American groups to examine patterns of Old World conquests. Multivariate statistics detected significant group differences for both size and shape (centroid size, p < 0.0001; shape, p < 0.0001) and showed that while significantly different, all the Mexican groups are more similar to one another except for one prehistoric inland‐western Mexican group, which is morphologically distinct from the other Mexican groups. Previous mtDNA research in these areas shows a low prevalence of African American admixture and a high indigenous component in the northern Mexican groups, which is consistent with the findings of this paper. The prehistoric and historic Mexican groups were the most similar indicating the retention of indigenous admixture after contact. The results from this analysis demonstrate that all groups are significantly different from one another supporting other findings that have shown that the indigenous populations of the New World are heterogeneous and that this variation may also contribute to the heterogeneity of contemporary populations.

A Generalization of the Utility Theory Approach To the Problem of Spatial Interaction

The derivation of the gravity model from utility theory is reformulated and generalized in order to show (1) how both the number of trips to individual destinations and the total travel budget may be determined simultaneously, and (2) how the effect of both distance and destination quality on trip distribution and total budget may be analyzed. Results are compared with the revealed space preference approach and are found to be superior in dealing theoretically with trip frequency and the effects of spatial context. For empirical applications, however, the revealed preference approach is advantageous.     

Measuring Similarity Among Various Shapes Based on Geometric Matching

The purpose of this article is to examine how to measure the degree of similarity among various shapes, including for the first time those that are fragmented and perforated, by the overlap-based elongation index. It is argued that complete removal of the effects of position, size, and orientation on shape, which is essential for the calibration of shape similarity, can be achieved by a shape similarity index that varies continuously with changes in shape. After examining the characteristics of shape change, it is demonstrated that the elongation index is sensitive to changes in the shape of two spatial objects only when the centroids of the two objects are coincident. Two related rules of shape similarity are then presented. The applicability of the elongation index is evaluated by comparing several simple and complex shapes. The principal contribution of this article is that for the first time similarity among various shapes, fragmented or perforated, can be identified using the elongation index.

The Numerical Study of Base-Isolated Buildings Under Near-Field and Far-Field Earthquakes

The behavior of base-isolated building frame is investigated with the help of a numerical study for far-field and near-field earthquakes with directivity and fling-step effects. Both design-level and extreme-level earthquakes are considered. Selected response parameters are peak floor displacement, acceleration, base shear, and isolator displacement. Inelastic behavior of base-isolated structure during the earthquake is investigated performing nonlinear time history analysis of a ten-story building frame. This study shows that base isolation is not effective for near-field earthquakes. Even for design-level earthquake, the frame gets significantly into inelastic range for earthquakes with fling-step effect.
