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

No full textAcclaimed South African "born journalist and author Benjamin Pogrund is widely known for covering the lives of black South Africans, including the Sharpeville massacre and the views of African leaders on political issues, and reporting on conditions in white prisons. He is described in his police file as "one of the strongest and most effective critics of the South African government.
Can We Tell Stories Out of Our Memories? The Contributions of Derrida and Benjamin
No full textThe author draws from Jacques Derrida’s and Walter Benjamin’s writings on
memory in order to argue that as these two thinkers deal with the simultaneity
of the diachronic and synchronic dimension of time they open up the
possibility of thinking about the relation between memory and narrative in a
more complex way. These two theorists affirm the discontinuity and the nonrecognition
between past events and present discourses and show the danger of
conflating memory and narrative without the awareness of its limits
Fourier transforms of Nilpotent Orbits, limit formulas for reductive lie groups, and wave front cycles of tempered representations
No full textThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Mathematics, 2011.Cataloged from PDF version of thesis.Includes bibliographical references (p. 54-56).In this thesis, the author gives an explicit formula for the Fourier transform of the canonical measure on a nilpotent coadjoint orbit for GL(n, R). If G is a real, reductive algebraic group, and O C g* = Lie(G)* is a nilpotent coadjoint orbit, a necessary condition is given for 0 to appear in the wave front cycle of a tempered representation. In addition, the coefficients of the wave front cycle of a tempered representation of G are expressed in terms of volumes of precompact submanifolds of certain affine spaces. In the process of proving these results, we obtain several limit formulas for reductive Lie groups.by Benjamin Harris.Ph.D
Amustaline-glutathione pathogen-reduced red blood cell concentrates for transfusion-dependent thalassaemia
No full textTransfusion-dependent thalassaemia (TDT) requires red blood cell concentrates (RBCC) to prevent complications of anaemia, but carries risk of infection. Pathogen reduction of RBCC offers potential to reduce infectious risk. We evaluated the efficacy and safety of pathogen-reduced (PR) Amustaline-Glutathione (A-GSH) RBCC for TDT. Patients were randomized to a blinded 2-period crossover treatment sequence for six transfusions over 8–10 months with Control and A-GSH-RBCC. The efficacy outcome utilized non-inferiority analysis with 90% power to detect a 15% difference in transfused haemoglobin (Hb), and the safety outcome was the incidence of antibodies to A-GSH-PR-RBCC. By intent to treat (80 patients), 12·5 ± 1·9 RBCC were transfused in each period. Storage durations of A-GSH and C-RBCC were similar (8·9 days). Mean A-GSH-RBCC transfused Hb (g/kg/day) was not inferior to Control (0·113 ± 0·04 vs. 0·111 ± 0·04, P = 0·373, paired t-test). The upper bound of the one-sided 95% confidence interval for the treatment difference from the mixed effects model was 0·005 g/kg/day, within a non-inferiority margin of 0·017 g/kg/day. A-GSH-RBCC mean pre-transfusion Hb levels declined by 6·0 g/l. No antibodies to A-GSH-RBCC were detected, and there were no differences in adverse events. A-GSH-RBCCs offer potential to reduce infectious risk in TDT with a tolerable safety profile
A low cost modular actuator for dynamic robots
No full textThesis: S.M., Massachusetts Institute of Technology, Department of Mechanical Engineering, 2018.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 89-91).This thesis details the hardware and control development for a low-cost modular actuator, intended for use in highly dynamic robots. A small 12 degree of freedom quadruped robot has built using these actuators, on which several control experiments have been performed. Despite the relatively low cost of the actuators, the quadruped has demonstrated unprecedented dynamic behaviors for a robot of this scale and number of degrees of freedom, such as a full 360° backflip from standing on flat ground. Several other implementations of these actuators are also discussed, a including bilateral teleoperation and haptic feedback system and a 6 degree of freedom lower-body biped robot.by Benjamin G.

Emulation is the most sincere form of flattery : retro videogames, rom distribution and copyright
No full textThe Internet has made it possible for amateur game creators to collaborate on projects irrespective of geographical location. The success of projects such as Minecraft, and even CounterStrike, demonstrates that ‘indie’ developers can create entertainment products just as popular and successful as mainstream developers with huge budgets. However, many individuals instead are more interested in the old than the new – reliving past experiences through the playing of old videogames that are no longer commercially sold. Through the creation of emulators, and the ripping of ROM images (data that allows for the playing of an emulated videogame, such as Super Mario Bros. on the Super Nintendo), games with nostalgic value can be easily distributed, played and replayed. In addition, this allows for the preservation of legacy content that may otherwise be consigned to the ‘dustbin of history’. However, irrespective of the effort and ingenuity that goes into the creation of emulation software, and the effort involved in ripping ROM data to make old games playable, are these pursuits entirely legal? The purpose of this paper is to consider the compatibility of such projects with pre-existing norms of intellectual property law, comparing and contrasting the approaches of US and EU IP regimes in their handling of emulators and ROMS. The paper will analyse the issue under pre-existing legislation and with regard to relevant case law, seeking to draw conclusions on whether the existing regimes in copyright law are compatible and satisfactorily balance the right of videogame publishers to seek fair remuneration for their work with the desire by enthusiasts to preserve and relive a form of creative culture
Coordination Geometry and Oxidation State Requirements of Corner Sharing MnO6 Octahedra for Water Oxidation Catalysis: An Investigation of Manganite (γ-MnOOH)
No full textSurface-directed corner-sharing MnO¬6 octahedra within numerous manganese oxide compounds containing Mn3+ or Mn4+ oxidation states show strikingly different catalytic activities for water oxidation, paradoxically poorest for Mn4+ oxides, regardless of oxidation assay (photochemical and electrochemical). This is demonstrated herein by comparing crystalline oxides consisting of Mn3+ (manganite, γ-MnOOH and bixbyite, Mn2O3), Mn4+ (pyrolusite, β-MnO2) and multiple monophasic mixed-valence manganese oxides. Like all Mn4+ oxides, pure β-MnO2 has no detectable catalytic activity, while γ-MnOOH (tetragonally distorted Mn3+O6, D4h symmetry) is significantly more active, and Mn2O3 (trigonal antiprismatic Mn3+O6, D3d symmetry) is the most active. γ-MnOOH deactivates during catalytic turnover simultaneous with the disappearance of crystallographically defined corner-sharing Mn3+O6 and the appearance of Mn4+. Comparing 2D-layered crystalline birnessites (δ-MnO2), the monovalent Mn4+ form is catalytically inert, while the hexagonal polymorph, containing few out-of-layer corner-sharing Mn3+O6, has ~10-fold higher catalytic activity than the triclinic polymorph, containing in-plane edge-sharing Mn3+O6. These electronic and structural correlations point towards the more flexible (corner shared) Mn3+O6 sites, over more rigid (edge shared) sites as substantially more active catalytic centers. Electrochemical measurements show and ligand field theory predicts that among corner shared Mn3+O6 sites, those possessing D3d ligand field symmetry have stronger covalent Mn-O bonding to the six equivalent oxygen ligands, which we ascribe as responsible for more efficient and faster electrolytic water oxidation. By contrast, D4h Mn3+O6 sites have weaker Mn-O bonding to the two axial oxygen ligands, separated electrochemical oxidation waves for Mn and O, and are catalytically less efficient and exhibit slower catalytic turnover. By controlling the ligand field geometry and strength to oxygen ligands we have identified the key variables for tuning water oxidation activity by manganese oxides. We apply these findings to propose a mechanism for water oxidation by the CaMn4O5 catalytic site of natural photosynthesis.This document is the Accepted Manuscript version of a Published Work that appeared in final form in ACS Catalysis, copyright © American Chemical Society after peer review and technical editing by the publisher.
