In most European countries, legislation exists about airborne sound insulation in dwellings, including facades. Mainly in southern Europeans countries, the glazed windows of building facades normally have shading systems to minimize the excessive heating of interior rooms due to the solar rays incidence and to provide for darkening of the room. The effect regarding sound isolation of those shading systems is usually not analyzed in the buildings acoustic project. This study presents values of weighted sound reduction index (Rw) provided by several shading system types (outside screens and interior screens) and presents a simple model to predict their sound reduction index.

Abstract
Inspired by Queen Elizabeth I's Poor Laws, Jane Addams espoused the rhetoric of social justice. Addams is an example of social reform between 1890 and 1930s as tied to eugenics, which is also evident in disagreements between Addams and Ida B. Wells. Despite the contributions of white women to social work, their subtle transgressions exist behind the veil of a feminist façade. It operates as a culture of ideas, and ultimately a prescribed assortment of race-based behaviours. Leading white women such as Addams dedicated their careers aloof to the subjugation of non-white issues that Ida B. Wells challenged via lynching. After constant prodding from Wells, Addams emerged from her silence to oppose lynching. Wells responded to Addams' discourse that she viewed as passive white rhetoric. According to contemporary descriptive data, white women/students are similarly aloof to non-white issues provoking womanism in response to feminism's Women's Ku Klux Klan. Ultimately, in the rescue of social justice, white women activists, including Social Work students, must denounce the feminist façade that social justice rhetoric and social justice activism coalesce for all oppressed populations.

Using green façades in large cities with hot climates has been introduced in the search for more sustainable solutions for urban development. This paper presents the data collected in situ and quantifies the thermal external behaviour of a green wall and a bare one in the same surrounding environment in the city centre of Madrid, Spain. The methodological approach helps to assess the impacts of both walls on the variation of the urban temperature range at the microclimate scale in accordance with environmental physical data at different seasons and times of the day. In the summer campaign, the maximum values of air temperature reduction as measured in situ range between 2.5 °C and 2.9 °C which confirmed the values of various other studies using similar measurements. In the autumn campaign, the maximum values were half of the ones obtained for the summer, not exceeding 1.5 °C. However, these values increased after calculating similar conditions of sunlight in both façades. This comparative analysis of the experimental results on a green wall and a bare wall demonstrates that green façades can have a significant temperature reduction potential in the surrounding microclimate. ; The authors are grateful to the European Union Erasmusþ Program for funding the Portuguese researchers' trips and visits to ...

L'Indo-Pacifique est un concept nouveau visant à rassembler un vaste ensemble territorial baigné par deux océans. Ce sont des espaces qui ont connu de grandes mutations depuis des décennies du fait des différents niveaux de développement économique de ses composantes. Au travers des matières premières et des biens manufacturés conteneurisés se déploient tant des enjeux de macroéconomie que des questions de développement (stratégique ou pas) par le biais des outils que sont les navires et les ports. Souvent observés du point de vue géopolitique du fait de leurs rivalités de toutes natures, les pays de l'IP sont aussi des pays avec une forte dimension d'économie maritime et en interaction les uns avec les autres. Dans ce contexte, la Chine semble être le pivot de tout, même s'il ne faut pas oublier le Japon, l'Australie et l'Inde. L'IP se caractérise, ce qui est d'ailleurs valable pour le reste du monde, par un enchevêtrement de relations économiques dont la mer est le lien et qui traduit la grande complexité des rapports interétatiques.
