Bottom-Up Identification of Subsystems in Complex Governance Systems

Theories of policymaking often focus on subsystems within a larger, overarching governance system. However, subsystem identification is complicated by the complexity of governance systems, characterized by multiple, interrelated issues, multi-level interactions, and a diverse set of organizations. This study suggests an empirical, bottom-up methodology to identify subsystems. Subsystems are identified based on bundles of similar observed organizational activity. The study further suggests a set of three elementary criteria to classify individual subsystems. In order to prove the value of the methodology, subsystems are identified through cluster analysis, and subsequently classified in a study of Swiss water governance. Results suggest that Swiss water governance can be understood as a network of overlapping subsystems connected by boundary penetrating organizations, with high-conflict and quiet politics subgroups. The study shows that a principled analysis of subsystems as the interconnected, constituent parts of complex governance systems offers insights into important contextual factors shaping outcomes. Such insights are prerequisite knowledge in order to understand and navigate complex systems for researchers and practitioners alike.     

Radiographic examination of Western bronze and stone sculptures: history of studies, methodologies and data interpretation

过去五十多年里,在对意大利的石雕和大型青铜雕塑进行保护时,各种跨学科的深度评估方法得到了建立。在此框架内,射线照相检测技术取得了进步。射线照相术作为一种无损的研究手段,可以从宏观层面对艺术作品进行考察,在文物评估中一直发挥着核心作用。在检测阶段,射线照相术既可以被用来重构古代艺术工艺和流程,也可以被用来评估文物的机械和结构信息。本文介绍了射线照相术的研究历史及其不同方法,比如中能X射线的使用、高能X射线的应用(线性加速器)、伽马放射性同位素源的使用(伽马射线照相术)。本文描述了射线照相术在石质和青铜雕塑上的重要应用案例,其中对马可·奥勒留骑马像的研究就是一个典型。本文还描述了“高能X射线”的首次应用,该技术被用来检测奥维多大教堂的圣母子、两组天使和一个青铜天篷雕塑。文章的结论部分定义了正确解释数据结果的必要标准,特别是在通过射线照相检测技术探究青铜雕塑检测信息和铸造工艺的相关性时,应该考虑到铸造缺陷和不连续性。     

Hypodontia of permanent teeth among Middle Palaeolithic hominids: an early case dated to ca. 92 000±5000 years BP at the Qafzeh site

The analysis of the maxillae and mandible belonging to a Middle Palaeolithic child has provided evidence of the early appearance of a developmental dental anomaly among Homo sapiens. The material came from the Near Eastern site of Qafzeh. In the mandible there was agenesis of the left second premolar and congenital absence of the right could not be totally excluded. Additional analyses including two presumed cases of dental development anomalies within contemporaneous prehistoric populations showed that tooth agenesis also can affect the anterior region of the mandible, and could be clearly separated from ante-mortem tooth loss caused by trauma. © 1998 John Wiley & Sons, Ltd.     

‘Are We Ready?’: Belgium and the Entente’s Military Planning for a War Against Germany, 1906–1914

Abstract

While historians have consistently focused on the development of German, French, and British planning in the years preceding the Great War, few have truly acknowledged neutral Belgium’s role in defining the strategic paradigm of 1914. Belgium held the strategic key to the opening salvos of a future Franco-German war, and each of its Guarantors were determined to obtain the initiative. While German planners were prepared to seize it by force, the Entente (particularly Britain), remained wary of its obligations. Instead, Britain sought to determine Belgian intentions and capabilities through secret and unbinding staff conversations in 1906 and 1912. The former proved useful in establishing a framework for co-operation but ultimately came to nothing. By the time they were resumed in 1912, Anglo-Belgian diplomatic relations had soured, while Belgium’s military reforms and its emergence as a colonial power gave it a renewed sense of confidence. Belgian officials were determined to retain the kingdom’s agency in the formulation of its defence policy and resented Entente suggestions of pre-emptive action. Neutrality was subordinated to independence, which itself could not be guaranteed were Belgium to conclude even the loosest of military accords. Consequently, Entente plans were forced surrender the strategic initiative to the Germans.

Use of Pushover Analysis for Predicting Seismic Response of Irregular Buildings: A Case Study

Structural irregularity undermines capability of conventional methods for 2D pushover analysis to closely approximate results from inelastic dynamic analysis. In recent years, different methods have been developed to overcome such limitation and their suitability has been checked with reference either to idealized building models or to geometrically simple tested structures. In this paper, suitability of one such method, proposed by Fajfar et al. [2005] Fajfar, P., Maru?i?, D. and Perus, I. 2005. Torsional effects in the pushover-based seismic analysis of buildings. Journal of Earthquake Engineering, 9(6): 831–854. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], is evaluated considering an existing school building which presents both vertical and plan irregularities. Types of irregularity encompass not only those usually considered by seismic codes but also those deriving from a bad conceptual design and construction inaccuracies, very frequent at the year of construction (1974). It is found that, even under such complex irregularity conditions, this ‘modified’ pushover analysis correlates well results from inelastic dynamic analysis almost up to failure, since, in most cases, its predictions of interstorey drifts and plastic rotations are conservatively close to values from inelastic dynamic analysis. Even failure mechanism, consisting of a floor mechanism at the third level, is correctly predicted, thus demonstrating adequacy of such method for actual framed structures.     

The Groin Vaults of St. John Hospital in Jerusalem: An Experimental Analysis on a Scale Model

The St. John Hospital is part of a larger complex of buildings known as the Hospitallers Quarter, located south of the Holy Sepulchre in Jerusalem. At present, the hospital looks like an irregular volume both in height and in plan; it is covered by ten groin vaults resting on very stocky pillars. Each vault is formed by intersecting double curvature surfaces. In order to verify the effectiveness of continuous carbon fiber reinforced polymer sheets reinforcement, bonded at the extrados of vaults, laboratory tests were carried out on a 1:5 scale model, built with materials and construction techniques similar to those of the real building. Experimental tests were performed on the unstrengthened and strengthened vault. The experimental results shown that the strengthening system is able to increase the collapse load of the vault, without substantial variation of the initial stiffness.     

Network Dynamics in Natural Resource Governance: A Case Study of Swiss Landscape Management

Structural characteristics of social networks have been recognized as important factors of effective natural resource governance. However, network analyses of natural resource governance most often remain static, even though governance is an inherently dynamic process. In this article, we investigate the evolution of a social network of organizational actors involved in the governance of natural resources in a regional nature park project in Switzerland. We ask how the maturation of a governance network affects bonding social capital and centralization in the network. Applying separable temporal exponential random graph modeling (STERGM), we test two hypotheses based on the risk hypothesis by Berardo and Scholz (2010) in a longitudinal setting. Results show that network dynamics clearly follow the expected trend toward generating bonding social capital but do not imply a shift toward less hierarchical and more decentralized structures over time. We investigate how these structural processes may contribute to network effectiveness over time.
