Molecular devices and machines: Hybrid organic-inorganic structures
No full textObjective: In this review we present the general principles that are at the basis of the construction of artificial molecular devices and machines and the main characteristics of these systems with a special focus for the kind of energy inputs needed to make them work. Methodology: By the bottom-up (chemical) approach science and technology move from micro- to nanoworld, and due to the nature of inputs (light and chemical) they move from electronics to photonics and chemi-onics. Furthermore the chemical molecule-by-molecule bottom-up approach offers unlimited opportunities for design and construction of nanoscale supramolecular structures, by combining the high precision of the chemical synthesis and scientists with a device driven-ingenuity. Furthermore, because the ability to perform specific functions as a response to external stimuli depends directly on the chemical nature and properties of the component units, in this review, we illustrate some examples of molecular devices and machines based on specific molecular units that have been developed in the research group of one of the authors. They are systems exhibiting pseudorotaxane, rotaxane, catenane and dendrimer structures that incorporate redox- and/or photoactive moieties. Conclusion: The future development of this kind of research will lead to more and more sophisticated artificial molecular devices and machines with better performances regarding their stability, switching, speed, and functions performed. We foresee that they will find useful applications in various fields, like energy conversion, sensoring, catalysis, and will give a great contribution in solving the present-day main problems regarding food, health, energy supply, and environment protection

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
