No full textThe authors regret that one of their coauthors, Oliver S. Hutter, was omitted from the original publication due to an oversight. Dr. Hutter was responsible for performing a large part of the experiments on bulk crystalline materials. The authors therefore take this opportunity to include Dr. Hutter on the author list and extend their apologies to him for the earlier oversight
Copper light-catching electrodes for organic photovoltaics
No full textOptically thin copper films with a random array of sub-optical wavelength apertures couple strongly with light in the wavelength range 600–800 nm due to excitation of surface plasmonic resonances. Herein we show that this trapped light can be used to excite electronic transitions in a nearby strongly absorbing organic semiconductor before the plasmonic excitations dissipate their energy as heat into the metal. This energy transfer process is demonstrated using model small molecule and polymer photovoltaic devices (based on chloro-aluminium phthalocyanine:C60 and PCE-10:PC70BM heterojunctions respectively) in conjunction with a nano-hole copper electrode formed by thermal annealing an optically thin Cu film supported on polyethylene terephthalate. The efficiency of this process is shown to be highest for wavelengths in the range 650–750 nm, which is part of the solar spectrum that is weakly absorbed by today's high performance organic photovoltaic devices, and so these findings demonstrate that this type of electrode could prove useful as a low cost light catching element in high performance organic photovoltaics
"Introduction to 'Walter Scott: New Interpretations'"
No full textThe Yearbook of English Studies for 2017 is dedicated to new interpretations of Walter Scott. Edited by Susan Oliver, the volume brings together fifteen essays by scholars from Australia, Europe and the Americas. These contributions represent vital and diverse directions in Scott studies, two hundred years after the celebrated ‘author of Waverley’ followed his early career as an antiquarian and poet with best-selling novels, verse dramas and a variety of prose non-fiction. The collection aims to extend our understanding of Scott’s literary works, public persona, home, onward influence as an authorial presence, and circle of associates. A conceptual framework that incorporates materialist, theoretical, textual, literary-historical and editorial approaches asks how critical enquiry into this globally influential author can most constructively move forward.
The essays are grouped in five themed sections. Beginning the volume, Section I looks into the transmission and afterlives of Scott’s writing, his persona as an author, and his home at Abbotsford. Section II is concerned with contemporary theoretical and critical approaches to Scott. The third group of essays focuses on his poetry, an area in which there is still relatively little published scholarship. In Section IV, it is Scott’s treatment of history and social conflict that provides the framework of enquiry. The concluding group of essays takes Scott criticism into the contemporary critical fields of literary geographies, island and Northern studies, antipodean studies, environmental justice and ecocriticism.
Contributors’ individual enquiries include life writing and archival research; theatre and performance; translation studies; disability studies; theories including ontology and problems relating to materialism and spirituality; the practical considerations of editing a new edition of Scott’s poetry; Scott’s representation of law; a postcolonial exploration of silence and absence; and matters relating to place, space and the natural world
Returning culture to peacebuilding : contesting the liberal peace in Sierra Leone
No full textThis thesis investigates the advantages and limitations of applying culture to the analysis of violent conflict and peacebuilding, with a particular focus on liberal peacebuilding in Sierra Leone. While fully aware of the critique of the concept of culture in terms of its uses for the production of difference and ‘otherness,’ it also seeks to respond to the critique of liberal peacebuilding on the account of its low sensitivity towards local culture, which allegedly undermines the peace effort. After a careful examination of the terms of discussion about culture enabled by theoretical approaches to conflict in Chapter 2, the thesis presents a theoretical framework for the analysis of cultural aspects of conflict and peace based on the processes and effects of meaning-generation (Chapter 3), developing the conceptual apparatus and vocabulary for the subsequent empirical study. Instead of bracketing out the recursive nature of cultural theorising, the developed approach embraces the recursive dynamics which arise as a result of cultural ‘embeddedness’ of the analyst and the processes which s/he seeks to elucidate, mirroring similar dynamics in the cultural production of meaning and knowledge. The framework of ‘embedded cultural enquiry’ is then used to analyse the practices of liberal peacebuilding as a particular culture, which shapes the interaction of the liberal peace with its ‘subjects’ and critics as well as framing its reception of the cultural problematic generally (Chapter 4). The application of the analytical framework to the case study investigates the interaction between the liberal peace and ‘local culture,’ offering an alternative reading of the conflict and peace process in Sierra Leone (Chapter 5). The study concludes that a greater attention to cultural meaning-making offers a largely untapped potential for peacebuilding, although any decisions with regard to its deployment will inevitably be made from within an inherently biased cultural perspective
PANDANGAN DUNIA DALAM NOVEL OLIVER TWIST KARYA CHARLES DICKENS
No full textOliver Twist by Charles Dickens is a novel which is analysed in
this research. The novel consists of the author�s negative view towards
Jews through one of characters named Fagin. The author keep giving bad
image towards a Jewish character in the novel as an evil or villainous
character. The bad description about the Jew not only on his performance,
but also on his words, behavior, and his place.
The purpose of this research is to determine world vision of the
author�s social class in Oliver Twist by using theory of genetic
structuralism from Lucien Goldmann. Having analysed the structure of
the novel and the structure of social structure of English society in
nineteenth century, the result of this research shows that there is coherence
between them in relation with negative description towards Jews.
The structure of Oliver Twist consists of binary oppositions which
come to one center opposition, harmony and disharmony. The cathegory
of characters in the novel consisits of characters who represent God,
cahracters who represent the world, and characters who represent human.
The characters who represent human must choose between God and the
world, or take both of them at once. Based on cathegorization of characters
which is analized, there is different attitude towards Jewish character and
non-Jewish characters by the author. The discriminative attitude shows
that there is an influence of antisemitism world vision on the author.
The negative desciption toward Jews character in Oliver Twist has
proved that there is antisemitism world vision as representation of the
social class� world vision of the author, Charles Dickens, who come from
middle class of English society in the nineteenth century

Single-junction solar cells based on p-i-n GaAsSbN heterostructures grown by liquid phase epitaxy
No full textIn this paper, we present single heterojunction p-i-n GaAsSbN/GaAs solar cells grown by low-temperature liquid-phase epitaxy (LPE) – this is of interest as a component of multi-junction solar cell devices. The quaternary absorber layer was characterized by low excitation power photoluminescence to give the temperature dependence of the bandgap. This conformed to the Varshni function at low temperatures to within 10 meV, indicating relatively small alloy potential fluctuations. The absorption properties and the transport of the photogenerated carriers in the heterostructures were investigated using surface photovoltage method. A power conversion efficiency of 4.15% (AM1.5, 1000 W·m−2) was measured for p-i-n GaAsSbN/GaAs solar cells, which is comparable to the efficiency of MOCVD grown devices of this type. This is promising for the first report of LPE grown GaAsSbN/GaAs solar cells since the current record efficiency for the cells based on these compounds grown by MBE stands just at 6%. The long-wavelength photosensitivity of the cells determined from external quantum efficiency and surface photovoltage measurements was shown to be extended to 1040 nm
THE ROLE OF EZIO’S STRUGGLE IN ITALIAN REVOLUTION ERA IN OLIVER BOWDEN’S ASSASSIN’S CREED RENAISSANCE
No full textKeywords:  Assassin’s Creed Renaissance,  Assassin,  Templar, ItalianRenaissance, Manifestation of Struggle, Historical Approach  Renaissance is one of the most crucial moments in human civilization history. In this era, the art, science, and technology developed significantly, and people were gaining their freedom to stand between worldly and religion purpose. Assassin’s Creed Renaissance is a historical-fictional novel which elevated the Italian Renaissance theme and the author, Oliver Bowden, illustrates it by exposing the main character action, Ezio Auditore, in struggling for freedom and justice. The application of historical approach in this study is to dig out how important the role of Ezio and his allies to influence the revolution of Italy. Furthermore, it used to explore the conflict between Assassin and Templar, and find the comparison between the fictional evidence and the fact in historical record to clarify the analysis. The result of the study  discovers  that  Oliver Bowden’s  Assassin’s Creed Renaissance  elaborates  the effort of Ezio and his allies as a process to reach a revolution. Various conflicts between Assassin and Templar are clearly described in the novel. Likewise the combination of historical fact and fictional aspect is also successfully described. As the first novel of  Assassin’s Creed  franchise, the next researchers who are interested in revolution concept can do a research to another novel, or even the newest one, Assassin’s Creed Forsaken using the same perspective
Poison in Paradise: Guam Disease
No full textGuam disease, found only on that small Pacific island, causes symptoms strikingly similar to Parkinson?s, Lou Gehrig?s, and Alzheimer's diseases, but it is not hereditary. In this program, neurologist/author Oliver Sacks travels to Guam in order to investigate this lethal illness. Prior studies done by epidemiologists, toxicologists, anthropologists, and other neurologists have raised suspicions over the water supply, the soil, the local fish, and even the nuts of indigenous cycads. However, as scientists continue to study and hypothesize, incidence of this disease that has plagued the islanders for a century is dropping. If a cure is to be discovered?providing valuable insights into other neurological disorders?it will have to be soon, or Guam disease may disappear on its own. A BBC Production. (50 minutes, color
the social stratification in Charles Dicken`s Oliver Twist an undergraduate thesis
No full textLiterature is a depiction of life as outlined by the author in writing. The depiction of this life includes social, political, and economical aspects. These aspects indirectly form a separation layer or one's position in society. This research focused on the social stratification in Charles Dickens’s Oliver Twist. The research focuses on two research questions formulated into: 1). How is the social stratification in Charles Dickens’s Oliver Twist? 2). What the aspects of social stratification are found in Charles Dickens Oliver Twist? The researcher uses descriptive qualitative methods and mimetic approach by M.H Abrams's. Mimetic approach is seeing a literary work as an imitation, or shadow, or a representative of the world and human life.The results of research indicates that Charles Dickens presents the social stratification in his novel, Oliver Twist in three ways: 1). Showing social classification, 2). Showing the differences between each class, and 3). Showing conflict between classes of society. In addition, there are three aspects of society in the Charles Dickens novel Oliver Twist, namely: 1). Human behavior (dominance), 2). Family (honorary), and 3). Commodity (properties)
