Lydia S. Wierman letter to Thomas Earl
No full textLetter from Lydia S. Wierman to Thomas Earl of Philadelphia, care of George Forman. Wierman's letter has been truncated somewhat -- here, we have only pages 4 and 5 of what presumably is a longer letter. Weirman speaks eloquently and passionately about the life and work of her brother, abolitionist Benjamin Lundy. Page 4 of the letter opens in the midst of recounting a story by which someone crawls to safety in a wintry woods. The letter continues in a consideration of Lundy's tremendous life's work in abolitionism from Wierman's perspective. Benjamin Lundy (1789-1839) was a prominent Quaker abolitionist best known for his development of abolitionist periodicals. His Genius of Universal Emancipation was first published in 1821 from his home in Mt. Pleasant, Ohio, and enjoyed a wide circulation across the antebellum United States. In the 1820s, the young William Lloyd Garrison came to work for The Genius. Benjamin Lundy traveled widely seeking subscriptions to The Genius, giving talks a
Public worship and practical theology in the work of Benjamin Keach (1640-1704)
No full textThe late seventeenth century was a critical and fruitful period
for the Particular Baptists of England. Severely persecuted following
the Restoration, toleration in 1689 brought its own perils.
Particular Baptists were fortunate in having several strong leaders,
especially the London trio of Hanserd Knollys, William Kiffin, and
Benjamin Keach. Such a small and severely persecuted group as the
Baptists could afford little time for academic pursuits, thus of
necessity most of their theology was practical in nature.
Benjamin Keach (1640-1704) was the most outstanding practical
theologian among the English Particular Baptists of the late
seventeenth century. This dissertation is a study of Keach, in
particular his writings on public worship and practical theology.
Although Keach was a prolific author, he has been almost completely
neglected by scholars.
After a biographical sketch of Keach, this study considers his
writings on public worship and practical theology. In the area of
worship, Keach made two outstanding contributions: First, he was the
most vocal apologist for Baptist views on Baptism of his period.
Secondly, and more importantly, his hymn writing and defense of hymn
singing broke new ground, not just for Baptists, but for English
Protestantism, in general. In addition to his contributions in these
areas, he also dealt with the laying on of hands and the sabbath day
worship controversy.
Keach's contributions to practical theology fall into two main
groups: his writings that concern religious education and those that
deal with polity. In addition to these, Keach's vigorous advocacy of
a high Calvinist soteriology are also considered under the rubric of
practical theology. Keach's most important (although not his most
positive) contribution in this area were his soteriological writings.
Although well within the bounds of orthodoxy, some of the tendencies
in Keach's soteriology were taken up by the following generation of
Baptist leaders and developed into a stultifying hyper-Calvinism that
handicapped Baptist evangelism and missions.
In the conclusion, Keach's contributions to a theory of practical
theology are considered

Stratospheric geoengineering with black carbon aerosols
No full textI use a general circulation model of Earth's climate to simulate stratospheric geoengineering with black carbon aerosols, varying the altitude of injection, initial particle size, and whether the deposited black carbon modifies ground albedo. 1 Tg of black carbon aerosols injected into the stratosphere each year will cause significant enough surface cooling to negate anthropogenic warming if the aerosols are small (r=0.03 μm) or if the aerosols are injected into the middle stratosphere, although using small aerosols causes large regional cooling effects that would be catastrophic to agriculture. The aerosols cause significant stratospheric heating, resulting in stratospheric ozone destruction and circulation changes, most notably an increase in the Northern Hemisphere polar jet, which forms an Arctic ozone hole and forces a positive mode of the Arctic Oscillation. The hydrologic cycle is perturbed, specifically the summer monsoon system of India, Africa, and East Asia, resulting in monsoon precipitation collapse. Global primary productivity is decreased by 35.5% for the small particle case. Surface cooling causes some sea ice regrowth, but not at statistically significant levels. All of these climate impacts are exacerbated for small particle geoengineering, with high altitude geoengineering with the default particle size (r=0.08 μm) causing a reasonable amount of cooling, and large particle (r=0.15 μm) geoengineering or particle injection into the lower stratosphere causing few of these effects. The modification of ground albedo by the soot particles slightly perturbs the radiative budget but does not cause any distinguishable climate effects. The cheapest means we investigated for placing 1 Tg of black carbon aerosols into the stratosphere by diesel fuel combustion would cost 541 billion annual, or 2.0% and 0.8% of GDP, respectively. The additional carbon dioxide released from combusting diesel to produce these aerosols is about 1% of current emissions, but the additional NOx would be 17% of current sources and could further reduce the total ozone column by up to 10%. Geoengineering with carbon black, if technically feasible, would be much cheaper, costing approximately 1.3 billion annually, with few troublesome emissions factors.Ph.D.Includes bibliographical referencesIncludes vitaby Benjamin S.

More than just victims: the truth about human trafficking
No full textBenjamin S Buckland argues that the language used to debate human trafficking can cloud the issue itself. Exploitation is only one side of the story. Deep-rooted socioeconomic and political reasons explain why some people fall into illegal or forced migration channels, and tackling these fundamentals requires a new language to acknowledge the agency and ambition of trafficked persons.

Tuckerton Peninsula Salt Marsh System: A Sentinel Site for Assessing Climate Change Effects
No full textThe Tuckerton Peninsula forms a large expanse (~2,000 ha) of highly inundated Spartina alterniflora salt marsh habitat along the southern New Jersey coast. Temporal and spatial changes in emergent salt marsh vegetation were characterized in three segments (northern, central, and southern) of the peninsula as part of a larger investigation to establish this salt marsh system as a sentinel site to assess future climate change effects in New Jersey. Monthly quadrat sampling at 90 plots along 9 transects in the peninsula during the June-September period in 2011 recorded 7 species of marsh plants (Spartina alterniflora, S. patens, Distichlis spicata, Salicornia spp., Limonium carolinianum, Morus rubra, and Symphyotricum tenuifolium). Measurements collected on maximum canopy height, shoot density, and percent areal cover of the marsh plant community in the heavily ditched northern segment were compared to those of the marsh plant communities in the shoreline-altered southern segment and the less impacted central reference segment. In general, species composition was similar between segments and no significant differences were found in maximum canopy height, shoot density or percent cover for any individual species. Spartina alterniflora was the dominant species. For all species combined, maximum canopy height and shoot density were higher and percent cover lower in the heavily ditched northern segment than in the other segments. No significant differences were found between the central and shoreline-altered southern segments for any of the three variables. Changes occurring in the demographic and ecological characteristics of the emergent salt marsh habitat in the peninsula are important for understanding future habitat change in other coastal wetlands of New Jersey and the mid-Atlantic region subjected to rising sea level and inundation.Manuscript title: Climate Change Effects on Plant Community Characteristics in the Tuckerton Peninsula Salt Marsh SystemPeer reviewe
Saber do tempo: tradição, experiência e narração em Walter Benjamin.
No full textThe following article discusses the concepts of tradition,
experience, and narrative in Walter Benjamin´s philosophy, from the perspective of
educational research. As a critical thinker and protector of culture, Walter Benjamin tried
to relate in one philosophical system the multiplicity of knowledge. In Benjamin´s
thoughts, the experience (the erfahrung) sustains a close relationship with religion and
society. To this extent this paper aims at investigating, beyond the philosophical knowledge
of the author, the anthropological references which constitute the mystic and political
core of Benjamin’s thought about the concept of experience and analyzing the implication
of tradition in the experience of language, history, art and education.Este artigo investiga os conceitos de tradição, experiência e narração em Walter Benjamin
com face à pesquisa em educação. Walter Benjamin foi, por certo, um dos pensadores
mais preocupados em conjugar num sistema filosófico a multiplicidade do conhecimento.
Essa sentença pode ser verificada a partir da compreensão da relação que o autor estabelece
entre a experiência (Erfahrung), a tradição e a narração. Benjamin indica, com efeito,
através dessa relação, o fundo místico, misterioso, sobre o qual se funda um tipo específico
de experiência que se refere (e depende) diretamente ao comunitário. É nesse sentido
que se pode visualizar com maior nitidez a implicação da tradição não apenas sobre o
pensamento do filósofo em questão, como também sobre algumas perguntas que se
fazem em torno da própria experiência da linguagem, da história, da arte e da educação

Sharp ill-posedness result for the periodic Benjamin-Ono equation (ERRATUM : PAPER WITHDRAWN)
No full textERRATUM : This paper has been withdrawn by the author since there were errors in the calculus of the defect coefficient in Page 11. The corrected calculus gives actually zero which do not lead to a contradiction on the continuity of the flow-map of the Benjamin-Ono equation. The author warmly thank Professor Patrick Gérard for having pointing out this error to him.ERRATUM : This paper has been withdrawn by the author since there were errors in the calculus of the defect coefficient in Page 11. The corrected calculus gives actually zero which do not lead to a contradiction on the continuity of the flow-map of the Benjamin-Ono equation. The author warmly thank Professor Patrick Gérard for having pointing out this error to him. (We prove the discontinuity for the weak L^2(\T) -topology of the flow-map associated with the periodic Benjamin-Ono equation. This ensures that this equation is ill-posed in H^s(\T) as soon as and thus completes exactly the well-posedness result obtained by the author.
Clade divination – phenotypic data facilitates epidemiological inferences from soybean dwarf virus sequence analysis
No full textSoybean dwarf virus (SbDV; family Tombusviridae, genus Luteovirus, species Luteovirus glycinis), transmitted solely by aphids in a persistent manner, can cause significant losses in cultivated Fabaceae. SbDV isolates are categorised into four strains; YP, YS, DP and DS. Yellowing (Y) and dwarfing (D) strains differ in their symptom expression and host range. P strains are transmitted by Acyrthosiphon pisum (pea aphid), and S strains are transmitted by Aulacorthum solani (foxglove aphid). Genetically, Y and D strains separate into two clades at every genomic region except for the N-terminal region of the read through domain (N-RTD) in which P and S strains separate. SbDV diversity in Australia has yet to be significantly investigated and so complete genome sequences were obtained from 41 isolates infecting cultivated Fabaceae in two regions of Australia (‘northeast’ and ‘southwest’). Phylogenetic analyses were conducted on the whole genome and the N-RTD of these sequences together with 50 sequences available on GenBank. At the whole genome level, isolates separated into D and Y clades. At the N-RTD level, with two exceptions, isolates separated into P and S clades. All south-west isolates were in the Y clade, whilst north-east isolates were in both the Y and D clades. All isolates sequenced were in the P group suggesting Ac. pisum is the primary vector of SbDV in these regions. Although biological evidence suggests S strain isolates are common in the southeast of Australia, just one previously sequenced Tasmanian isolate was available and was in the Y and S clades. Relevant biological data available for each isolate supported inferences made from phylogenetic clade. This study suggests that at least three of the four SbDV strains are present in Australia and is an example of the importance of continued collection of phenotypic data to provide more power to genetic analyses
