The evaluation of the shear behavior of masonry walls is a first fundamental step for the assessment of existing masonry structures in seismic zones. However, due to the complexity of modelling experimental behavior and the wide variety of masonry types characterizing historical structures, the definition of masonry’s mechanical behavior is still a critical issue. Since the possibility to perform in situ tests is very limited and often conflicting with the needs of preservation, the characterization of shear masonry behavior is generally based on reference values of mechanical properties provided in modern structural codes for recurrent masonry categories. In the paper, a combined test procedure for the experimental characterization of masonry mechanical parameters and the assessment of the shear behavior of masonry walls is presented together with the experimental results obtained on three stone masonry walls. The procedure consists of a combination of three different in situ tests to be performed on the investigated wall. First, a single flat jack test is executed to derive the normal compressive stress acting on the wall. Then a double flat jack test is carried out to estimate the elastic modulus. Finally, the proposed shear test is performed to derive the capacity curve and to estimate the shear modulus and the shear strength. The first results obtained in the experimental campaign carried out by the authors confirm the capability of the proposed methodology to assess the masonry mechanical parameters, reducing the uncertainty affecting the definition of capacity curves of walls and consequently the evaluation of seismic vulnerability of the investigated buildings.

Information Intermediaries

Real estate is a revelatory industry for the study of ICT uses because it is information-intensive and realtors are information intermediaries between buyers and sellers. As agents, buyers and sellers increase their uses of ICT, they also change how they approach their daily work. Information intensive industries, by their nature, show the greatest impacts due to ICTs that enable information sharing and the bypassing of traditional information intermediaries. However, while the effects and uses of ICT are often associated with organizations (and industries), their use occurs at the individual level. In other words, it is changes to individual work related to the use of ICTs that reshape both organization and industry structures, and vice-versa. In this study, we use activity theory to provide an analytic perspective within the setting in Malaysia. Data reveal historical structures of this industry guiding the day-to-day work of agents, buyers, sellers and the role of agency. Many of these structures are embodied in a set of explicit contracts that reify existing structures and legitimize realtors’ actions. While looking from the agencies practices, we explain possible improvement in the real estate industry following the advancement of internet & mobile technology, viewing the possibilities towards the use of IOT in real estate industry.

Typical Process

This work performed a comparative analysis between the construction process carried out when building the dome at the Temple of Santa Lucía, in Ambalema-Colombia and the typical process of an octagonal dome. Additionally, the structural stability is assessed of the dome of the case study against service and dynamic loads. To compare with the case study, known domes were taken as examples from structures in Italy and Spain. The analysis includes a study on the dome’s geometry and the constructive errors found. Methodology: The dome’s stability was evaluated through structural analysis software for which the dome was simplified into a system of four articulated arches. Conclusions: As a result, it was found that the dome of the temple of Santa Lucía does not have a system to counteract lateral thrusts (a drum or its similar), which permitted the appearance and widening of meridional cracks. These cracks propagate from the base to the crown, but do not compromise the structure’s stability for service loads. The analysis for seismic loads indicates that the dome is at risk of collapse upon seismic events, even of moderate magnitudes. Originality: The study is aimed at architects and engineers interested in the theme of restoration of historical structures.

Disciplinary Affiliation

Feminism provides a worldview with innovative possibilities for scholarship and activism on behalf of families and intimate relationships. As a flexible framework capable of engaging with contentious theoretical ideas and the urgency of social change, feminism offers a simultaneous way to express an epistemology (knowledge), a methodology (the production of knowledge), an ontology (one’s subjective way of being in the world), and a praxis (the translation of knowledge into actions that produce beneficial social change). Feminist family science, in particular, advances critical, intersectional, and queer approaches to examine the uses and abuses of power and the multiple axes upon which individuals and families are privileged, marginalized, and oppressed in diverse social contexts. In this paper, I embrace feminism as a personal, professional (academic), and political project and use stories from my own life to illuminate broader social-historical structures, processes, and contexts associated with gender, race, class, sexual orientation, gender identity, age, nationality, and other systems of social stratification. I provide a brief history and reflections on contemporary feminist theory and activism, particularly from the perspective of my disciplinary affiliation of feminist family science. I address feminism as an intersectional perspective through three themes: (a) theory: defining a critical feminist approach, (b) method: critical feminist autoethnographic research, and (c) praxis: transforming feminist theory into action. I conclude with takeaway messages for incorporating reflexivity and critical consciousness raising to provoke thought and action in the areas of personal, professional, and political change.
