No full textMassachusetts Ave. facade (has two story retail wing at left); In 1955, Sert founded a studio in Cambridge, Massachusetts, which in 1958 became a partnership with Huson Jackson and Ronald Gourley. Sert was the Graduate School of Design dean when he designed the building. Holyoke Center, which occupies a full city block in the heart of Harvard Square, is a ten-story, 360,000 square foot facility. The main plan of the concrete structure is H-shaped, with the north wing along Massachusetts Avenue and south wing along Mt. Auburn Street. The central connecting portion sets back from both Dunster Street and Holyoke Street and is approximately the same width as the two wings. Holyoke Center is the main administration building of Harvard University. It includes underground parking, the arcade, shops, and a bank at street level, university offices above, and a fully equipped infirmary, and University Health Services. At street level, a pedestrian arcade, occupying two stories in height, runs through the block. The building is set for renovation in 2016 and has been renamed.

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
Firm Size, Technical Change and Wages: Evidence from the Pork Sector from 1990-2005
No full textA long-standing puzzle in labor economics has been the positive relationship between wages and firm size. Even after controlling for worker's observed characteristics such as education, work experience, gender, and geographic location, a significant firm size wage effect averaging 15 percent remains. This paper investigates whether the size-wage premium on hog farms persists over time and whether the magnitude is growing or shrinking. The paper pays particular attention to the matching process by which workers are allocated to farms of different size and technology use, and whether the matching process may explain differences in wages across farms. The study relies on four surveys of employees on hog farms collected in 1990, 1995, 2000, and 2005. The survey was conducted across the United States. The data allow us to evaluate how farm size and technology adoption have changed over time and how employee pay has changed in response to these changes. Detailed investigations of these pay differences between small and large hog farms and between farms using few and many technologies show that the differences cannot be explained away by differences in the education, work experience, or geographic location of the farm. Although more educated and experienced workers are more likely to work on larger and more technologically advanced hog farms, the positive relationships between wages and both farm size and technology remain large and statistically significant when differences in observable worker attributes are controlled. Furthermore, these effects are reinforcing in that large hog farms also adopt more technologies, and so the firm size effect persists even after differences in the number of technologies are held constant. The size-wage and technology-wage prema have persisted over time, and we cannot reject the null hypothesis that the premia are constant over the sample period.Agribusiness, Livestock Production/Industries,

Electrocatalytic CO2 reduction by aminopyridine cobalt complexes: electronic effect of substituents on the pyridyl ring and mechanistic insights
No full textIn the last decade, several earth-abundant metal-based molecular catalysts have been found highly active for the photochemical or electrochemical CO2 reduction. However, despite their efficiency for the light-driven CO2-to-CO process,1 the electrocatalytic performances of Co complexes containing N4 or N5 ligands are still generally affected by catalyst deactivation,2 large overpotentials3 and low faradaic yields, due to either ligand decomposition or a preferential H2 evolution pathway under acidic conditions.4 To overcome these barriers, design of novel Co catalysts should be coupled to a deep understanding of the electrocatalytic mechanism, based on the characterization of key intermediates formed during the process. 5
Herein, we present a series of novel synthesized [CoII(Y,XPyMetacn)(OTf)2] complexes (1R, Scheme 1) containing N4 tetradentate ligands with general formula Y,XPyMetacn (1-[2′-(4-Y-6-X-pyridyl)methyl]-4,7-dialkyl-1,4,7-triazacyclononane),6 employed as catalysts for the electrochemical reduction of CO2. The introduction of different substituents at the - and -positions of the pyridine allowed us to systematically evaluate the effect of the electronic properties of the ligand on the catalytic activity. As highlighted by the electrochemical data, the redox non-innocent character of the Y,XPyMetacn ligand is extremely sensitive to the substitution at the pyridyl ring, and influences not only the E1/2(CoII/I) value, but also the nature of the reduction event itself, thus leading to different reactivity of the electrochemically generated CoI species towards CO2. Moreover, extensive spectroscopic (NMR) and spectroelectrochemical (IR and UV-Vis) studies were carried out to investigate the intermediates produced in the course of the catalytic process. Theoretical modelling provided also key mechanistic details for the CO2 reduction reaction.

No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
