慕陵拟建方城明楼史实探赜

道光帝的慕陵是清代最特殊的帝陵,先前曾因东陵宝华峪地宫浸水而废弃,后又于西陵龙泉峪重建,规制并“概从撙节”,自出机杼。本文探究道光帝对传统帝陵规制大加裁削的原由,指出咸丰帝即位后曾拟建慕陵明楼方城,并详加规划,最终却在各种因素掣肘下偃旗息鼓。     

偃师商城小城的建筑年代与性质

偃师商城小城建筑年代为南关外期偏晚,这一年代非早商而属先商晚期即夏末。该城是商汤灭夏之时兴建的军事营垒,非早商都城。     

The IJsselcog project: from excavation to 3D reconstruction

The 15th‐century IJsselcog was lifted in 2016 from the river IJssel near Kampen (the Netherlands). From stern to bow and from starboard to portside about 70% of the original wooden hull is preserved. The combined approach of analogue documentation and photogrammetry enabled the research team to reconstruct the original ship in 2D and 3D, followed by a comprehensive study of its nautical characteristics. The hull volume and height were maximized by the shipbuilders using previously unknown construction elements in cogs, such as wales and vertical riders; shipbuilding traits that are generally applied to 16th‐ and 17th‐century carvel‐built cargo ships.     

从域外领土到飞地社区：人文地理学中的飞地研究进展

飞地是一个经典的地理学概念,也是一个重要的空间分析视角。目前国内关于飞地的研究日益增多,但对其内涵的梳理仍显不足,多种定义并存,并出现概念泛化的现象。在此背景下,本文对已有的飞地概念及其内涵进行了梳理,指出从域外领土、经济飞地到飞地社区的内涵演变历程,并根据飞地的宗主地-东道地关系,将其划分为行政飞地、经济飞地、飞地社区和飞地国家4种类型。本文研究指出,飞地概念的核心是其宗主地-东道地-飞地的三方构图,依托这一视角可以对当前的异域领土、经济飞地、乃至城市内部的族裔聚居区进行多尺度的空间分析,从飞地的不同功能出发,可以对其展开多维度的地理学透视,为进一步的实证研究和相关政策实施提供参考。     

Understanding online information experiences: simulated,personalized and epistemological

This paper addresses the idea of having ‘information experiences’ in our information society, a concept that prevails in the business world but is under-explored in the sociological study of information. From the literature, I identify the three theoretical approaches to these experiences as simulated, personalized and epistemological, and adopt an interpretivist approach to explore how recent trends manifest. Simulated experience is closely related to ‘virtuality’, a concept developed in the early days of the internet, while personalized experience arises out of participation in social websites. Centring on the third, I use data from Yam’s case studies on Wikipedia and further propose three factors that sustain the discursive environment of epistemological experience.     

Hungry Translations: The World Through Radical Vulnerability

The dominant landscape of knowledge and policy rests on a fundamental inequality: bodies who are seen as hungry are assumed to be available for the interventions of experts, but those experts often obliterate the ways that the hungry actively create politics and knowledge by living a dynamic vision of what is ethical and what makes the good life. Such living frequently involves a creative praxis of refusal against imposed frameworks. Learning from such refusals requires hungry translations that are open and flowing and that are embedded in embodied solidarities that require radical vulnerability. Such translations strive to converse across incommensurable landscapes of struggles and meanings in order to co‐agitate against universalised languages that erase the vocabularies and visions of those who are reduced to hungry bodies. In reconceptualising politics as a shared and unending labour on an uneven terrain that makes perfect translation or retelling impossible, hungry translation becomes a continuous collective praxis of troubling inherited meanings of the social, and of making our knowledges more alive to the creativity of socio‐political struggle. Such hungry translations must fearlessly move between worlds in search of poetic justice and social justice without defining an origin or destination and without compromising the singularities that constitute each community of struggle.     

Recovery of a lost wall painting at the Etruscan Tomb of the Blue Demons in Tarquinia (Viterbo,Italy) by multispectral reflectometry and UV fluorescence imaging

This paper presents the results of a multispectral reflectometry and ultraviolet (UV) fluorescence study on the entrance wall of the Tomb of the Blue Demons in the Necropolis of Monterozzi (450–430 bc ) in Tarquinia (Viterbo, Italy), which is a UNESCO site. The technique is based on the acquisition of a multispectral set ranging from 10 to 25 images, acquired at wavelengths between 370 and 1120 nm, with a spectral width of 50 nm per image, using both halogen lamps for visible and infrared images and high‐purity UV diodes for fluorescence. Blind‐source separation algorithms were then applied to the whole image set to extract from the resulting images the details not otherwise visible in the single spectral images. The multispectral technique presented was tested and improved upon over the last decade on ancient Etruscan and Roman wall paintings and, because of its quickness and cost‐effectiveness, it can now be proposed as a powerful tool for the study of poorly conserved archaeological wall paintings and a preliminary diagnostic survey before any future conservation intervention on them.     

Material Modeling in the Dynamic Nonlinear Analysis for Recycled Aggregate Concrete Structures

Dynamic mechanical tests of recycled aggregate concrete (RAC) test units confined by transverse hoop reinforcement are carried out. The effects of the strain rate, hoop reinforcement confinement, and replacement ratio of recycled coarse aggregate (RCA) on the mechanical properties of confined recycled aggregate concrete (CRAC) are thoroughly analyzed and assessed. The strain-rate-dependent constitutive model of CRAC is proposed for the high strain rate representative of seismic conditions. A three-dimensional discrete numerical model, based on the proposed rate-dependent material model of CRAC, is established to investigate and evaluate the dynamic nonlinear behaviors of RAC structures.     

The Dynamics of the Electoral Geography of the Five Star Movement: The Role of Territorial Area and Municipality Size

ABSTRACT

The aim of the article is to trace the evolution of the Movimento 5 Stelle (Five Star Movement [M.5.S.]) over the last four national elections (the 2013 and 2018 general elections and the 2014 and 2019 European elections). In particular, our goal is to understand how the electoral support for the party changed, in the context of the broad transformations of the Italian electoral geography. In order to accomplish this goal, we investigate the explanatory role of the spatial dimension on electoral support, specifically in terms of geographical zone and municipality size. The M.5.S. is also compared with the two parties that reported the best results in the last European elections: the Lega (League) and the Partito Democratico (Democratic Party [P.D.]). Our results show that the recent European elections do not represent a turning point in the (electoral and geographical) history of the M.5.S.: its territorial rooting in the south of the country and in medium-sized municipalities are present from the 2014 European elections onwards. Interpretations and implications of these findings are discussed in the conclusions.
