Considering research enquiry into biophilic urbanism and office worker productivity

In cities, people spend a significant portion of their time indoors, much of which is in office buildings. The quality and nature of these spaces have the potential to be a strong determinant of people’s health and wellbeing. There is a body of evidence that suggests experiences of nature increase the rate of attention recovery, reduce stress, depression and anxiety, and increase cognitive abilities. Further, the presence of nature inside buildings (such as pot plants and internal green walls) can improve indoor air quality, potentially reducing illness and increasing cognitive function. Urban design that integrates nature into the built environment to provide these benefits, among others, is called ‘biophilic urbanism’ and is the subject of growing international interest and research. The potential for these benefits to increase worker productivity in office buildings is of particular interest, as this could significantly increase the financial performance of office building-based organisations. However, productivity is a complex concept that is difficult to define, and affected by a multitude of factors, which make it difficult to measure. This inability to quantify productivity increases from investments in nature- experiences in office buildings is currently a significant barrier to such investments. Within this context, this paper considers opportunities for research to explore the relationship between office-based nature experiences and productivity, by reviewing existing research in this field and reflecting on the authors’ own experiences. This review has a particular focus on the importance of quantifying this link in order to encourage private property owners to voluntarily integrate nature into buildings to provide city-wide ecosystem service benefits. The paper begins with a contextual overview of how biophilic urbanism can potentially increase worker productivity. Existing methods of measuring and evaluating the performance of biophilic urbanism within the context of office buildings are then explored, along with a discussion of issues with such methods that are currently limiting investment in biophilic urbanism to increase worker productivity and wellbeing. This includes a summary of a survey within a Perth office building to explore the impact of views of nature through a window. Drawing on these insights, the paper makes recommendations regarding opportunities for focusing future investigations to enhance understanding of how biophilic urbanism can contribute to increased wellbeing and productivity in office buildings. This paper builds on work conducted as part of the Sustainable Built Environment National Research Centre Project 1.5, Harnessing the Potential of Biophilic Urbanism in Australia, which considered the role of nature integrated into the built environment in responding to emerging challenges of climate change, resource shortages and population pressures, while providing a host of co- benefits to a range of stakeholders.

A Comparative Study on Internationalization and the Role of International Offices at Selected Middle Eastern and German Universities

Internationalization of higher education has become one of the most important policies for institutions of higher education worldwide. Though universities are international by nature, the need for intensified quality activities of international nature has promoted internationalization to be under spotlight of researchers, administrators and policy makers and to be an area for research. Each institution follows its certain way to govern its international affairs. Most Universities, especially in the 'Developed World' started to plan it strategically. This study explores the meanings and importance of internationalization especially that it means different things to different people. It also studies the rationales behind internationalizing higher education. It focuses on the four main prevailing rationales; political, cultural/social, economic/financial, and academic on both national and institutional levels. With the increasing need to strategically plan, the study explores internationalization strategies in terms of how to develop them, what are their approaches and types, and their components and dimensions. Damascus University has witnessed an overwhelming development of its international relations and activities. Therefore, it started to face a problem of how to deal with this increasing load especially that its International Office is the only unit that deals with the international issues. In order to study the internationalization phenomenon at Damascus University, the 2WH approach, which asks the what, why, and how questions, is used and in order to define the International Office's role in the internationalization process of the University, it studies it and the international offices of Kassel University, and Humboldt University in Germany, The University of Jordan, and Al Baath University in Syria using the 'SOCIAL' approach that studies and analyses the situation, organization, challenges, involvement, ambitions, and limitations of these offices. The internationalization process at the above-mentioned Universities is studied and compared in terms of its meaning, rationales for both the institution and its academic staff, challenges and strategic planning. Then a comparison is made among the international offices of the Universities to identify their approaches, what led to their success and what led to their failure in their practices. The aim is to provide Damascus University and its International Office with some good practices and, depending on the experiences of the professionals of the case-studies, a suggested guidance to the work of this Office and the University in general is given. The study uses the interviews with the different officials and stakeholders of the case-studies as the main method of collecting the information in addition to site visits, studying their official documents and their websites. The study belongs to qualitative research that has an action dimension in it since the recommendations will be applied in the International Office. The study concludes with few learned lessons for Damascus University and its International Office depending on the comparison that was done according to a set of dimensions. Finally a reflection on the relationship between internationalization of higher education and politics, the impact of politics on Middle Eastern Universities, and institutional internationalization strategies are presented.

Comparación de las dinámicas de uso y apropiación del espacio público en parques de origen informal y formal: parque Villa de la Torre y parque Cayetano Cañizares

El interés de este estudio de caso es comparar las dinámicas de uso y apropiación del espacio público en parques de origen formal e informal, y discutir sus implicaciones en la vida social y urbana, teniendo como zonas el parque Villa de la Torre (informal) y el parque Cayetano Cañizares (formal). Este trabajo se enmarca en conceptos de uso y apropiación del espacio público, a partir de los cuales se examinan las dinámicas de formalidad e informalidad de los parques zonas de estudio, explorando qué efectos puede tener su origen, y revisando si el parque informal implica falta de apropiación y usos conflictivos, o si por el contrario, las dinámicas que en espacios públicos se dan pueden incluir dinámicas positivas y negativas indistintamente de su origen.

Sintesi e caratterizzazione di nanoparticelle di ossido di stagno dopate

In the last years, new materials have been developed in the broad area of nanoscience. Among them, an emergent class characterized by excellent electrical conductivity properties as well as high optical transmittance in the visible region are TCOs (Transparent Conducting Oxides). Due to their versatile properties, they have found many applications in a lot of optoelectronic devices, such as solar cells, liquid crystal displays, touch-panel displays, gas sensors, to cite a few examples. Different research groups have studied and characterized the TCOs. In this context, a new synthetic method has been developed to produce FTO nanocrystals (Fluorine-doped Tin Oxide NCs) in Prof. Pinna’s lab at the Humboldt University in Berlin. FTO belongs to the TCO category, and they have been studied as a promising alternative to ITO NCs (Indium Tin Oxide) which represent the standard TCO material in terms of properties and performances. In this work, FTO NCs have been synthesized using the “benzyl alcohol route” (a non-aqueous sol-gel method) via microwave, which permits to produce FTO particles with good properties as revealed by the characterizations performed, employing a cheap, fast and clean method.

Physical education enhances your concentration

There is growing evidence that physical education has not only positive effects on the physical health of children and adolescents, but also contributes positively to personality development and to performance in cognitive tasks. Existing studies indicate chronic as well as acute effects of physical education on cognitive performance. However, underlying mechanisms, required content of the physical intervention and duration of the effects are still unclear. In order to shed light on some of these open questions, the present study investigated the acute effects of a special form of physical education, integrating cardiac-stimulating tasks with executive demands, on the concentration of 11-year olds. Concentration was assessed three times using the d2-R Test. Intervention (n=38) and control group (n=35) did not differ in their d2-R performance in pre- nor in post-test, which took place after either a physical intervention or a normal core subject lesson respectively. In the follow-up test however, which was completed after two more core subject lessons for both groups, the intervention group improved more in their d2-R performance than the control group F(1, 71)=4.95, p=.03, indicating that physical education can positively influence children’s concentration, not immediately after the activity, but later on during the following school lessons.
