Introduction
Full text linkThis book is the first to examine intermediaries in a holistic and systematic manner. The classical model of face-to-face contracting between two individuals is no longer dominant. Instead, deals frequently involve a number of parties, often acting through intermediaries. As a result, it is important to understand the role and power of intermediaries.
Intermediaries tend to be considered within discrete silos of the law. But by focussing upon a particular, narrow area of law, lessons are not learned from analogous situations. This book takes a broader approach, and looks across the traditional boundaries of private law in order to gain a proper assessment of the role played by intermediaries.
A wide range of jurisdictions and topical issues are discussed in order to illuminate the role intermediaries play in commercial law. For example, the continued growth of electronic commerce requires consideration of the role of websites and other platforms as intermediaries. And developments in artificial intelligence raise the prospect of intermediaries being non-human actors. All these issues are subject to rigorous analysis by the expert contributors to this book
Variation in relative species abundance of reef fishes: drivers and ecosystem impacts
Full text linkCheng-Han Tsai studied deterministic versus stochastic variation in relative species abundance of reef fishes on the Great Barrier Reef. He found that reef fish assemblages are highly niche-structured by deterministic species differences, and this niche importance depend strongly on volatility in coral cover. Such covariation between niche importance and environmental volatility also influence the relationship between diversity and ecosystem stability among coral reefs
Locating the Belt and Road Initiative's spatial trilectics
No full textIn this paper, we survey the expanding body of literature on the Belt and Road Initiative (BRI) in Chinese and Anglophone geography, and locate the main lines of development. The emerging scholarship approaches the BRI as a spatial discourse and examines the production of geographical reasoning in statecraft. It also links up with studies of the BRI as both a material project and an everyday experience. We argue that it is in this combined understanding of BRI's multiple registers, as discourse, project, and experience, that a trilectical approach for future geographical engagement can be identified as the BRI edges to its second decade.</p

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
Effect of different irradiance levels on bioelectricity generation from algal biophotovoltaic devices / Thong Cheng Han
Full text linkPhotosynthesizing organisms including microalgae are exposed to varying levels of light irradiance throughout the day, thus sparking strong research interests in determining the effects of different irradiance levels on the efficiency of biophotovoltaic (BPV) platforms in generating bioelectricity. When light energy strikes the surface of the photosynthetic apparatus of algal cells, electrons are shuttled from the algal cells to the anode through a mediator but scientific findings have suggested that direct electron transfer from the microalgae to the anode could boost the efficiency of electron transport mechanism in a BPV device by reducing internal resistance (Ng et al., 2014a). In this study, mediator less anodes were adopted in the BPV devices by growing algal biofilms from suspension and immobilized Chlorella sp. (UMACC 313) cultures on ITO-coated glass anodes. Immobilized cultures were prepared by entrapping the microalgal cells in 2% sodium alginate solution. The BPV devices were illuminated by four different irradiance levels (30, 90, 150 and 210 µmol photons m-2 s-1 ) to investigate the relationship between varying irradiance levels on the power output of the devices. Photosynthetic performance of the microalgal cells was evaluated using Pulse Amplitude Modulation Fluorometer (PAM) on Days 0, 4, 8 and 12 of the experiment whereas power output of the BPV devices were found from polarization curves generated by applying external resistance stepping technique (Ng et al., 2017). The maximum power density and maximum current density were produced from alginate-immobilized biofilms at the irradiance level of 150 µmol photons m-2 s-1 . High Non-Photochemical Quenching (NPQ) readings at 150 µmol photons m-2 s-1 indicated effective photoprotection in Photosystem II (PS II) that prevents inactivitation of PS II when exposed to strong irradiance. Thelowest power output from immobilized cultures was recorded at 210 µmol photons m-2 s-1 , thus suggesting that partialphotoinhibition had occurred at high irradiance leve
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
