Farming on Top: Rooftop Agriculture for Healthy Cities
Full text linkThe world is facing many problems nowadays, including a growing number of people living in cities, many of whom often do not have easy access to fresh food. To solve this problem, it is necessary to develop a new kind of agriculture that provides city residents with food security while also protecting the environment. Rooftop agriculture could be a solution. Rooftop agriculture is a type of urban agriculture, in which food is grown on the tops of buildings. Rooftop agriculture can have many benefits. For example, it can reduce the extreme heat in the city during summer, it can help to decrease urban poverty, and it can help people to socialize more. In addition, rooftop agriculture can even benefit the buildings themselves. Rooftop agriculture is becoming more popular across the world, thanks to these benefits. We hope it will become an important part of the sustainable cities of the future
Efficient tree methods for option pricing
Full text linkThe aim of this dissertation is the study of efficient algorithms based on lattice procedures for dealing with two relevant issues arising in the recent literature on option pricing: the pricing of complex barrier-type options and the pricing of options when the equity model takes into account a stochastic interest rate. This research is developed with a twofold perspective: first, we propose a good solution from a numerical point of view through the introduction of efficient lattice procedures and secondly, we study the theoretical aspects related to the tackled problems (such as the convergence and the rate of convergence of the scheme proposed)
Data on the effects of supplemental LED light combined with defoliation on truss-tomato
No full textThe dataset contains the vegetative, physiological and qualitative data of greenhouse truss-tomato cultivated with a combination of defoliation and supplemental LED light. The defoliation factors consisted of the early removal of the leaves (R) right under the developing truss before the fruit turning stage and a non-removal (NR) during the entire cultivation cycle. The lighting factors consisted of an artificial LED lighting treatment with red and blue diodes for 16 h d^−1 (h 8-00) with an intensity of 180 μmol s^−1 m^−2 (RB) and a control cultivated under natural light only (CK)

Rooftop systems for urban agriculture
Full text linkUrban population growth, consequent competition in land use, climate change and lack of productive resources are some of the problems that are currently making necessary a new form of agriculture free from soil exploitation and able to ensure food security to urban dwellers in the most sustainable way. Rooftop farming is a form of building-base agriculture that may help to address not only global nutritional uncertainty, but also social, environmental and economic issues such as social exclusion, heat island effect, storm water damages and urban poverty. This chapter describes the forms, architecture, design elements and management of rooftop farming, as well as presenting case studies from around the world. Finally, the chapter looks ahead to future research trends in this area

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
