Lewis Acid Stabilized Methylidene and Oxoscandium Complexes
No full textThe methylidene scandium complex (PNP)Sc(mu(3)-CH(2))(mu(2)-CH(3))(2)[Al(CH(3))(2)](2) (PNP=N[2-P(CHMe(2))2-4-methylpheyl](2)(-)) can be prepared from the reaction of (PNP)Sc(CH(3))(2) and 2 equiv of Al(CH(3))(3). The Lewis acid stabilized methylidenes candium complex has been crystallographically characterized, and its bonding scheme analyzed by DFT. In addition, we report preliminary reactivity studies of the Sc-CH(2) ligand with substrates such as H(2)NAr and OCPh(2). While the former results in an Bronsted acid-base reaction, the latter reagent produces the olefin H(2)C-CPh(2) along with the novel oxoscandium complex (PNP)Sc(mu(3)-O)(mu(2)-CH(3))(2)[Al(CH(3))(2)](2), quantitatively
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
The modernist angel: Art at the Limits of the Human in D. H. Lawrence, H. D. and Mina Loy
No full textPhDThe subject of this thesis is a figure that might provisionally be called the *modemist
angel'. Focusing on modernist literature, and more particularly on the work of D. H.
Lawrence, H. D. and Mina Loy, it aims to isolate from the many angels found in all periods
and all types of art a historically specific and intellectually coherent paradigm: an angel of
and for its modernist times. A figure of precisely this type could be said to exist in the
form of Walter Benjamin's 'angel of history'. Critics who address the question of the
modern angel in texts by Franz Kafka and Rainer Maria Rilke often do so in conjunction
with the problem posed by the angel of history. Beginning with a chapter on Benjamin,
this thesis nevertheless follows a different trajectory. Over five chapters, it explores a
modernist landscape formed not only by Lawrence, H. D. and Loy, but also by European
and American writers such as A. R. Orage, Allen Upward, Ezra Pound, Wallace Stevens,
Havelock Ellis, Edward Carpenter, Sigmund Freud and Friedrich Nietzsche. Although the
angel that emerges from this investigation might, in some respects, be said to anticipate
Benjamin's later version, this figure is also very different, standing for a project that is
distinctively, and recognisably, modernist in nature. He/she (the sex of the modernist
angel is often open to question) represents an attempt to reconcile the divine
responsibilities of the artist with the material and gendered conditions of being,
specifically of being human, in the modem world. This thesis looks again at the clash of
intellectual paradigms in the early-twentieth century - notably, the confrontation of the
Romantic view of art as a superhuman or sacred undertaking with the psychoanalytical or
evolutionary idea that all human endeavour is underpinned by sub-human motives - and
suggests the angel as a new and instructive figure through which to think the perilous
limits between the human and the divine in modernist literature
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
Walter Benjamin: el naufragio ineluctable
No full textCon una nueva perspectiva sorprendente, en la que Walter Benjamin es visto como un “naufragio ineluctable”, este ensayo da cuenta del modo en que durante la agonía de la república de Weimar él había fracasado en casi todo. En el campo del trabajo, en el campo político, en el campo de su vida personal. Pero la mirada de Benjamin sobre Baudelaire vale también para él mismo: la realidad de la desdicha lejos de cancelar corrobora el hecho de que tenía todo para convertirse en una leyenda. Su naufragio revela un principio rector de la época. Un principio formulado en su obra sobre el barroco alemán: “En el Mal absoluto nuestra subjetividad reconoce su desdicha”. Benjamin describió este mundo desde la perspectiva de los marginados: la bohemia, el flaneur que se pierde en los pasajes de París, que desembocan en los grandes boulevares construidos por el barón de Hausmann. Siempre inquietado por descubrir en lo más insignificante lo más importante de un suceso. Sobre el concepto de la historia, que escribió después de su confi namiento en el campo de Nevers, en Francia, que padeció con Hannah Arendt y Arthur Köstler, vio la constitución real del mundo como un paisaje helado, donde la modernidad se transfigura en un cúmulo de ruinas. Su intervención monumental hace de él quizás el autor del que más se ha escrito en todo un siglo. Su crítica al mito del progreso lo ha convertido en un autor que sigue escribiendo incluso después de su muerte.With a surprising new perspective, in which Walter Benjamin is seen as a “ineluctable wreck”, this essay gives an account of the way that during the agony of the Weimar Republic he had failed in almost everything. In field of work, in political field and in his personal life. But Benjamin gaze´s on Baudelaire also applies to himself: the reality of the misery away from cancel corroborates the fact that he has everything to become a legend. His failure reveals a guiding principle of the age. A principle formulated in his work on the german baroque: “In the absolute Evil our subjectivity recognizes its misery”. Benjamin described this world from the perspective of the marginalized: the bohemia, the flaneur lost in the passages of Paris, which lead to the grands boulevards built by the baron Hausmann. Always attracted to discover in the most insignificant the most important of an event. On the concept of history, that he wrote after his confinement in the field of Nevers, in France, which suffered with Hannah Arendt and Arthur Köstler, he saw the constitution of the real world as a landscape ice, where modernity is transformed into a cumulus of ruins. For his intervention monumental he is perhaps the author about who exists more essays and written in a century. His criticism of the myth of progress has made him an author who keeps writing even after his death
Sea-Level change and subsidence in the Delaware Estuary during the last ~2200 years
No full textWe produced eight new sea-level index points that reconstruct a ~2.5 m relative sea-level (RSL) rise at Sea Breeze in the Delaware Bay from ~200 BCE to 1800 CE. The precision of our reconstruction improved upon existing data by using high-resolution surveying methods, AMS radiocarbon dating of in-situ plant macrofossils collected immediately above the basal contact between pre-Holocene sand and salt-marsh sediments, foraminifera as sea-level indicators, and by accounting for tidal range changes through time. Our new data were combined with a database of 65 sea-level index points available for the Delaware Bay to estimate the rate of RSL rise in the upper (1.26 ± 0.33 mm/yr) and lower bay (1.30 ± 0.36 mm/yr) using a spatial-temporal model. Correction for changes in tidal range through time removed the disparity in rate between the upper and lower Delaware Bay that had previously been postulated. After paleotidal correction, the rates of RSL rise estimated for the Delaware Bay (1.25 ± 0.27 mm/yr) correlate with the ~1.3 mm/yr rate reported for New Jersey, Maryland, and Virginia, and confirm that the maximal ongoing forebulge collapse along the U.S. Atlantic coast is focused on the mid-Atlantic.Peer reviewe
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.

Criticality of Regular Formulas
No full textWe define the criticality of a boolean function f : {0,1}^n -> {0,1} as the minimum real number lambda >= 1 such that Pr [DT_{depth}(f|R_p) >= t] = k.
In an unpublished manuscript [Rossmann, 2018], the author showed that a combination of Håstad’s switching and multi-switching lemmas [Håstad, 1986; Håstad, 2014] implies that AC^0 circuits of depth d+1 and size s have criticality at most O(log s)^d. In the present paper, we establish a stronger O(1/d log s)^d bound for regular formulas: the class of AC^0 formulas in which all gates at any given depth have the same fan-in. This result is based on
(i) a novel switching lemma for bounded size (unbounded width) DNF formulas, and
(ii) an extension of (i) which analyzes a canonical decision tree associated with an entire depth-d formula.
As corollaries of our criticality bound, we obtain an improved #SAT algorithm and tight Linial-Mansour-Nisan Theorem for regular formulas, strengthening previous results for AC^0 circuits due to Impagliazzo, Matthews, Paturi [Impagliazzo et al., 2012] and Tal [Tal, 2017]. As a further corollary, we increase from o(log n /(log log n)) to o(log n) the number of quantifier alternations for which the QBF-SAT (quantified boolean formula satisfiability) algorithm of Santhanam and Williams [Santhanam and Williams, 2014] beats exhaustive search
