Tintype of African American Man Standing at Wooden Fence [n.d.]

An unidentified African American man poses beside a wooden fence in the studio of an unknown photographer in this small black and white tintype photograph. A painted landscape serves as the backdrop. This tintype was in the possession of Iris Sloman Bell, of St. Catharines, Ontario. The Sloman - Bell families are descended from former American slaves who settled in Canada."Tintypes were the invention of Prof. Hamilton Smith of Ohio. They begin as thin sheets of iron, covered with a layer of black paint. This serves as the base for the same iodized collodion coating and silver nitrate bath used in the ambrotype process. First made in 1856, millions were produced well into the twentieth century. When tintypes were finished in the same sorts of mats and cases used for ambrotypes, it can be almost impossible to distinguish which process was used without removing the image to examine the substrate."

John Adams Smith letter, Jan. 14, 1813

Transcript: New York Jan. 14. 1813. My dear uncle, I had nearly concluded to have made my [jaunt?] earlier than I had mentioned in my last letter to you, for Swartout had intended to have written by me to Father & yourself; having [Louisa?] concluded not so soon to depart he sends me his letters which I forward in mail, I shall hope to have letters from home soon, it is a great pleasure to hear from any of you. I said last week in Hollands letter mentioning [bladeworth?] account, I have explained to him. It is a mistake about me agreeing to pay Mr. [Dening?] [their?] account. Caroline mentions to me your jaunt to [Sophia?], but I regret our friend there should be unpleasantly situated. I have not yet seen Col. Willett but will see him as mentioned. I have neglected to go there for some time which has been remiss in me. We have nothing new I believe unless it be that Armstrong & Jones of Philadelphia have been nominated as Secretarys of War & the Navy & [cer?] this in all probability may be appointed. There may be room for speculation, but perhaps it is not probable that Canada will be ceded to American Valor in the year 1813. There is a Bill before congress by which it may be made penal to enter on board American vessels, either British subjects or naturalized Americans, which it is presoomed by many will [spon?] the accommodation of Peace – may be yes may be no – the proof of the pudding is in the eating of it. I imagine pacification is not so near at hand although it is much to be desired. Whatever might be for the honor & prosperity of the Country I would strenuously advocate, aloof from partial & party considerations. We have not a word as yet what the Council at Albany may be thinking of as yet. I suppose these things will come in time, perhaps untimely to many. I desire for the present not to be found among the untimely. I am your sincerely, with love to all. John Adams Smith

La influencia de la construcción de identidad cultural vietnamita en la guerra de independencia de Vietnam (1946-1954)

La presente investigación tiene como objetivo explicar la influencia de la construcción de identidad cultural vietnamita en la Guerra de Independencia de Vietnam entre 1946 y 1954. Se argumenta que la construcción de identidad cultural justificó, promovió y legitimó la guerra de independencia como instrumento político ya que –en tanto proceso relacional– generó durante la colonización francesa prácticas de diferenciación fundamentadas en la reivindicación de los valores, tradiciones, costumbres, creencias y símbolos vietnamitas en torno a la resistencia. Ello propició una ruptura en las relaciones políticas imperantes, lo que condujo a la búsqueda de un nuevo orden social basado en la autodeterminación. Se utiliza una metodología de tipo cualitativa, fundamentada en el análisis documental e historiográfico.

Riesgo de accidentes biológicos en estudiantes de la salud: revisión de la literatura en los últimos 14 años.

Introducción: Todos los trabajadores del área de la salud están en riesgo de padecer un accidente biológico. No obstante los estudiantes de estas aéreas, pueden presentar más riesgo porque apenas están en formación y no tienen la práctica o experiencia suficiente. Existen varios artículos que han estudiado la incidencia y prevalencia de accidentes biológicos en los trabajadores del área de la salud, Sin embargo, sobre esta problemática de la población estudiantil del área de la salud, se encuentra menos literatura. Por lo tanto con esta revisión sistemática se busca analizar y actualizar este tema. Métodos: Se realizó una revisión de la literatura científica de artículos publicados en los últimos 14 años, en relación con la prevalencia de accidentes biológicos en estudiantes de medicina, odontología, enfermería y residentes del área de la salud a nivel mundial. Se llevó a cabo la búsqueda en la base de datos de Pubmed, encontrando un total de 100 artículos, escritos en inglés, francés, español o portugués. Resultados: Las prevalencias encontradas sobre accidentes biológicos en estudiantes fueron las siguientes: en países europeos a nivel de enfermería los valores oscilan entre 10.2 % a 32%, en medicina fueron del 16%-58.8%, y en odontología del 21 %. En países asiáticos, se encontró que en enfermería el porcentaje varía de 49%-96 %, en medicina van del 35% -68%, y en odontología varia de 68.a 75.4%. En Norte América, en medicina las cifras fluctúan alrededor del 11-72.7 % y en odontología giran alrededor del 19.1%. Finalmente respecto a Suramérica la prevalencia fue de 31.2 a 46.7% en medicina, y del 40% en enfermería. Conclusiones: Por lo anterior se pudo concluir que, la prevalencia de accidentes biológicos en los estudiantes del área de la salud es elevada y varía según el continente en el que se encuentren.

The transatlantic dimensions of the time lord: Doctor Who and the relationships between British and North American television

This chapter explores some of the textual specificity of the Steven Moffat/Matt Smith Doctor Who, in relation to its positioning within the current transatlantic television landscape. The chapter develops further the existing scholarship on Doctor Who, by both offering a critical assessment of the transatlantic dimensions of the Moffat/Smith-era Doctor Who, and by challenging some of the existing critical arguments about Doctor Who's transatlantic dimensions. Particular attention is paid to the casting, physicality and costuming of actor Matt Smith as the Doctor in relation to notions of Britishness.

Ecological niche modeling and geographical distribution of pollinator and plants: A case study of Peponapis fervens (Smith, 1879) (Eucerini: Apidae) and Cucurbita species (Cucurbitaceae)

The bees of the Peponapes genus (Eucerini, Apidae) have a Neotropical distribution with the center of species diversity located in Mexico and are specialized in Cucurbita plants. which have many species of economic importance. such as squashes and pumpkins Peponapis fervens is the only species of the genus known from southern South America The Cucurbita species occurring in the same area as P fervens Include four domesticated species (C ficifolia, C maxima maxima, C moschata and C pepo) and one non-domesticated species (Cucurbita maxima andreana) It was suggested that C. in andreana was the original pollen source to P fervens, and this bee expanded its geographical range due to the domestication of Cucurbita The potential geographical areas of these species were determined and compared using ecological niche modeling that was performed with the computational system openModeller and GARP with best subsets algorithm The climatic variables obtained through modeling were compared using Cluster Analysis Results show that the potential areas of domesticated species practically spread all over South America The potential area of P fervens Includes the areas of C m andreana but reaches a larger area, where the domesticated species of Cucurbita also Occur The Cluster Analysis shows a high climatic similarity between P fervens and C. m. andreana Nevertheless. P fervens presents the ability to occupy areas with wider ranges of climatic variables and to exploit resources provided by domesticated species (C) 2009 Elsevier B V All rights reserved
