Paper-like electronic displays: Large-area rubber-stamped plastic sheets of electronics and microencapsulated electrophoretic inks

Electronic systems that use rugged lightweight plastics potentially offer attractive characteristics (low-cost processing, mechanical flexibility, large area coverage, etc.) that are not easily achieved with established silicon technologies. This paper summarizes work that demonstrates many of these characteristics in a realistic system: organic active matrix backplane circuits (256 transistors) for large (≈5 × 5-inch) mechanically flexible sheets of electronic paper, an emerging type of display. The success of this effort relies on new or improved processing techniques and materials for plastic electronics, including methods for (i) rubber stamping (microcontact printing) high-resolution (≈1 μm) circuits with low levels of defects and good registration over large areas, (ii) achieving low leakage with thin dielectrics deposited onto surfaces with relief, (iii) constructing high-performance organic transistors with bottom contact geometries, (iv) encapsulating these transistors, (v) depositing, in a repeatable way, organic semiconductors with uniform electrical characteristics over large areas, and (vi) low-temperature (≈100°C) annealing to increase the on/off ratios of the transistors and to improve the uniformity of their characteristics. The sophistication and flexibility of the patterning procedures, high level of integration on plastic substrates, large area coverage, and good performance of the transistors are all important features of this work. We successfully integrate these circuits with microencapsulated electrophoretic “inks” to form sheets of electronic paper.

International conference paper presentations: A multimodal analysis to determine effectiveness

International conference presentations represent one of the biggest challenges for academics using English as a Lingua Franca (ELF). This paper aims to initiate exploration into the multimodal academic discourse of oral presentations, including the verbal, written, non-verbal material (NVM) and body language modes. It offers a Systemic Functional Linguistic (SFL) and multimodal framework of presentations to enhance mixed-disciplinary ELF academics' awareness of what needs to be taken into account to communicate effectively at conferences. The model is also used to establish evaluation criteria for the presenters' talks and to carry out a multimodal discourse analysis of four well-rated 20-min talks, two from the technical sciences and two from the social sciences in a workshop scenario. The findings from the analysis and interviews indicate that: (a) a greater awareness of the mode affordances and their combinations can lead to improved performances; (b) higher reliance on the visual modes can compensate for verbal deficiencies; and (c) effective speakers tend to use a variety of modes that often overlap but work together to convey specific meanings. However, firm conclusions cannot be drawn on the basis of workshop presentations, and further studies on the multimodal analysis of ‘real conferences’ within specific disciplines are encouraged.

El paper de l'etnobotànica en la consecució d'una alimentació saludable

A partir del problema de l'alimentació inadequada que segueix bona part de la població i les conseqüències que comporta en termes de salut (Varela, coord., 2013) s'aborda l'alternativa gastronòmica que representa el model alimentari de la Dieta Mediterrània (DM) per a fer front a molt d'aquests problemes, com també el paper que pot jugar l'etnobotànica en el procés de readaptació d'aquell model a la realitat del segle XXI i a la configuració d'una cultura aliffientària saludable i sostenible.

Conjectural restoration Indian College of 1655-56 to 1698 in Harvard College, photo lithograph on heavy paper, May 1934

Floor plans and front and end elevations of Indian College drawn by H.R. Shurtleff in May 1934 based on research conducted by Shurtleff from the Harvard College Records and surveys of local period buildings. Shows likely configuration of Indian College with lodging for 20 students, studies, and the printing room which housed the printing press.

Front elevation and floor plans for first and second floors, ink and wash on paper, [ca. 1812]

Drawing by Charles Bulfinch of proposed plans for University Hall which were later rejected. Includes sketches of the front exterior view of the University Hall, and separate floor plans for the ground and second floors. Bulfinch designed a ground floor with a chapel and four dining halls each holding 100 students, a second floor with a gallery in the chapel and three rooms over the dining halls for public examinations and meetings of the Corporation and Overseers; and a basement under the halls intended for a kitchen under the dining halls and recitation rooms under the chapel.

Paper wrapper formerly used to bundle records related to Nathan Prince, undated

Recto of wrapper reads: "Oct. 31, 1740 to June 24, 1742. Papers relative to the charges against & defence made by Nathan Prince in 1741. Examined & done with." Verso reads "Hon. President [Josiah] Quincy." These annotations suggest that the records in this collection were consulted by Quincy, who served as Harvard's President from 1829 to 1845. It is likely that he used them when writing his two-volume History of Harvard University, which includes a lengthy passage about Prince and his trials at Harvard.

Some account of a paper call'd the Telltale, begun in colledge Sept 1721

The small leather-bound volume holds two sections, a manuscript student periodical, and written tête-bêche, an exchange on smallpox inoculation followed by notes on the rules and activities of a Harvard College student club. The volume begins with thirteen numbered manuscript issues, written in one hand, of the Tell-Tale running from September 9, 1721 to November 1, 1721. Prefaced, "This paper was entitl'd the Telltale or Criticisms on the Conversation & Beheavour of Scholars to promote right reasoning & good manner," the work is modeled after literary periodicals of the time, including the "Spectator," and is considered the oldest student publication at Harvard. The periodical appears to have circulated in manuscript form. The content varies in format and includes letters between Telltale and correspondents, short essays, and advertisements. Topics discussed include conversation, detraction, and flattery. While not specifically about Harvard it does provide some information about the College including evidence of various student activities and organizations at Harvard in the 1720s. The entry explaining the rules of the Telltale Club is heavily faded and nearly illegible. The Telltale records multiple dreams, which are populated by various characters, such as “beautiful” Kate, two “learned Physicians” debating inoculation, “four Fellows” “pushing and shoving one another,” and a “person of a very Dark & swarthy complexion in a Slovenly Dress with 7 patches & 5 sparks on his Face.”

1 + 1 = 3? EU-US voting cohesion in the United Nations General Assembly. EU Diplomacy Paper 07/2012, September 2012

This paper investigates the factors that explain the voting cohesion of the United States (US) and the European Union (EU) on foreign policy issues in the United Nations General Assembly (UNGA). It is often argued that the EU and the US are simply too different to cooperate within international organizations and thus to vote the same way, for example, in the UNGA. However, there is still a lack of research on this point and, more importantly, previous studies have not analyzed which factors explain EU-US voting cohesion. In this paper, I try to fill this gap by studying voting cohesion from 1980 until 2011 on issues of both ‘high’ politics (security) and ‘low’ politics (human rights) not only as regards EU-US voting cohesion, but also concerning voting cohesion among EU member states. I test six hypotheses derived from International Relations theories, and I argue that EU-US voting cohesion is best explained by the topic of the issue voted upon, whether an issue is marked as ‘important’ by the US government, and by the type of resolution. On the EU level, the length of Union membership and transaction costs matter most.
