The increasing dimension and heterogeneity of global Web systems make their management with tools based on the client/server model more difficult. The mobile agent technology overcomes the limits of traditional approaches and proposes solutions that are suitable for the management of distributed and heterogeneous Internet‐based systems. The paper describes the MAMAS environment and its implementation with a mobile agent technology. MAMAS has the goals of monitoring the whole system, introducing dynamic corrective actions and modifying system policies at run‐time. MAMAS achieves these objectives by answering the guidelines of both security and compliance to standards. The choice of Java as the implementation language has made it possible to achieve portability, to exploit the language security features, and to provide Web accessibility. The MAMAS compliance with CORBA ensures interoperability with legacy management platforms.

The Internet is an open and global programming environment where applications and services mostly follow the traditional client/server model. The use of new programming paradigms based on mobile entities, such as mobile agents (MA), can accelerate the process of diffusion of new applications and services in the areas of e‐commerce, network and systems management, and mobile computing. However, the lack of security is one of the main obstacles to a wide diffusion of MA. On the one hand, mobility increases the potential of security breaches because of the injection of possibly malicious MAs; on the other hand, it introduces the new issue of protecting MAs against integrity and secrecy attacks from their execution environments. This paper discusses the security issues introduced by the MA technology and proposes a security architecture composed of a wide set of services and components, which adequately fulfil the requirements of several application areas. The implementation of the security framework in the secure and open MA system has provided the support for the development of a secure electronic marketplace prototype that demonstrates the effectiveness of adopting the MA technology in the Internet environment.

The performance of the building envelope of a large-scale public building significantly influences the energy consumption of such a building. This study aims to determine the best strategy for the envelope by examining the engineering design of the building in Nanchang University. The building shape coefficient, sun-shading strategies, window–wall ratio, roof, and walls were studied through a method involving multilayer feed-forward neural network model simulations. Results show that the optimum shape coefficient value is 0.32. The combination of interior and exterior blinds and electrochromic glass is the ideal option to reduce the increase in the energy consumption of the architecture caused by solar radiation. Maintaining the window–wall ratio at 0.4 is ideal. A green roof exerts a minimal effect on building energy consumption decrease (only 0.4%). Applying the strategy of vertical greening to the external wall can reduce cooling energy consumption by as much as 5.4%. Adopting the best envelope strategy combination can further decrease energy consumption by 20.8%. This strategy is also applicable to the middle and lower reaches of Yangtze River in China, which flow through Nanchang and have a climate similar to that of the said area. Future research should be directed toward applying artificial neural networks to quantitatively evaluate the effects of a design strategy and produce the best design strategy combination.

In contrast to liberal, orthodox Marxist and structural interpretations which attribute government policy in capitalist society to exogenous forces, the state regularly possesses a significant area of autonomy within which decisions are effectively determined by the political‐administrative elite (PAE). The majority of the economic projects emanating therefrom can be categorized as either aggrandizing populist or economistic. Postulates the choice of orientation depends upon PAE interests. Concludes that a purely aggrandizing project can be expected only in an environment of decisive underdevelopment while a populist one is almost inevitably a temporary response to conjunctural factors; most common, both in the advanced capitalist countries and the majority of Third World countries is a strong predisposition to an economistic project.

The purpose of this paper is to empirically evaluate the effect of heterogeneity in inter‐organizational collaboration networks on international high‐quality scientific performance of the most reputed business management schools in Latin America according to AméricaEconomía ranking.

Starting from the debate between advantages and disadvantages of heterogeneity in scientific performance framed in the debate between organizational population ecology and organizational institutionalism theories, this research explores the relationship between heterogeneity, reputation and the most important features for doing research. Using a binomial negative regression, the paper evaluates the partial effect of those variables in the count of scientific production.

There is an isomorphical tendency from the most reputed schools to establish heterogeneous networks, showing empirical evidence to normative proposals from Latin America, specially formulated in the light of Sabato triangle. Also there are differentiations between schools in aspects like human capital, double‐degree agreements, and schools’ trajectories.

It is necessary to choose a wider sample of schools and to include Latin American journals. The study of diversity (between researchers) and its relationship with heterogeneity (between organizations) is also needed.

The research shows that elite business management schools in Latin America that present better performance also present high levels of heterogeneity in their inter‐organizational collaboration. Therefore, the promotion of heterogeneity could enhance scientific performance and improve techno‐economical networks.

This research hopes to aim the research policy design to be able to steer and promote heterogeneity that could improve the relationship between producers and users of knowledge.

The relationships between reputation, heterogeneity, and scientific performance in administration in Latin America had not been addressed empirically. The worth of this research is the empirical confirmation to the advantages of heterogeneity, rather than intellectual capital features of schools, in research collaboration that contribute to the debate about heterogeneity and performance.

Evaluar empíricamente el efecto de la heterogeneidad de las redes de colaboración interorganizacionales en el desempeño científico de alta calidad internacional en las escuelas de administración y negocios más reputadas en América Latina de acuerdo con el escalafón de AméricaEconomía.

Con base en el debate que concierne a las ventajas y desventajas de la heterogeneidad en el desempeño científico enmarcado dentro del debate entre las teorías de la ecología de poblaciones y el institucionalismo organizacional, esta investigación explora la relación entre la heterogeneidad, la reputación y las características más importantes que pertenecen a la investigación. Usando la regresión binomial negativa, el artículo evalúa los efectos parciales de las variables en el conteo de la producción científica.

Hay una tendencia isomórfica de las escuelas más reputadas por establecer redes heterogéneas, mostrando evidencia empírica para las propuestas normativas de América Latina, especialmente formuladas a la luz del triángulo de Sabato. También hay diferencias entre las escuelas en términos del capital humano, los convenios de doble titulación, y la trayectoria de las escuelas.

Es necesario escoger una muestra más amplia de escuela e incluir a las revistas de América Latina. El estudio de la diversidad (entre investigadores) y su relación con la heterogeneidad (entre organizaciones) también es requerida.

La investigación muestra que las escuelas de administración en América Latina que presentan mejor desempeño también presentan altos niveles de heterogeneidad en su colaboración interorganizacional. Por lo tanto, la promoción de la heterogeneidad podría añadir al desempeño científico y mejorar las redes tecno‐económicas.

Esta investigación espera impulsar el diseño de políticas de investigación y a su vez promover la heterogeneidad que pueda mejorar la relación entre los productores y usuarios de conocimiento.

La relación entre reputación, heterogeneidad y desempeño científico en administración en América Latina no ha sido abordada empíricamente. El valor de esta investigación es la confirmación empírica de las ventajas de la heterogeneidad, en vez de otras características de las escuelas, en la colaboración científica que contribuye al debate sobre heterogeneidad y desempeño.

The purpose of this paper is to discuss the dynamics of the evolution of damage to the residential buildings within the city walls of Norcia during the six-month seismic swarm that hit Central Italy in the period 24th August 2016 to end of January 2019. This is accomplished by comparing the damage recorded by the Italian Civil Protection usability form (AEDES form) during this period after each event.

First, these outputs are compared with a qualitative assessment conducted by means of omnidirectional camera (ODC) imagery collected on site by the authors, to explore the ability of this technology to support post-earthquake damage assessment. The damage level attributed with these two techniques is then further compared with the output of the analytical vulnerability assessment method FaMIVE, which allows to correlate damage to vulnerability. Specifically, the objective is to investigate the efficacy and performance of historic and recent strengthening interventions.

Results show that there is a good correspondence between AeDES and ODC assessments for low to medium damage grades (DG). Discrepancies in higher DGs are discussed in light of the different levels of information that can be recorded by using the two tools. The efficacy of strengthening is also well captured by the FaMIVE method. The procedure estimates a decrease of almost 40, 25 and 20 per cent of the total number of buildings failing out-of-plane, respectively, for the three seismic events considered, when restraining elements are in action.

The analysis conducted in this work make use of deterministic values of Norcia’s masonry fabric characteristics that have been found in literature, thus implying that neither the probabilistic aspects nor the related uncertainties have been properly investigated and addressed. However, this limitation is to be considered within the more general context of the legislation for the preservation of historic buildings which limits substantially any type of semi-destructive tests, hence limiting the reliability of the values available in literature. This in turn affects the decisions informing the design and implementation of strengthening interventions which can be confidently considered reliable and effective.

The paper addresses for the first time a systematic investigation of damage progression in historic masonry structures, part of urban aggregates in heritage cities. The current urban fabric is discussed in view of historic building codes as the basis for determining the present seismic vulnerability of the historic city centre of Norcia. The study provides new data sets for the city of Norcia and develops a statistical correlation between cumulative damage and analytical vulnerability functions for heritage buildings exposed to a swarm of earthquakes. The analytical assessment of the effect of historic strengthening is totally novel.
