The Social Principles of Jesus: A Critical Re-examination of Walter Rauschenbusch’s Social Gospel

It has been nine decades since Walter Rauschenbusch (1861-1918) published a slim volume entitled The Social Principles of Jesus. Though today less well known than his other works Christianity and the Social Crisis (1907) and Theology for the Social Gospel (1917), it is Social Principles that most adeptly summarizes the theological ethics of Rauschenbusch’s “social gospel.” Taking the form of a pedagogical treatise, Social Principles reads as both a finely tuned analysis of the modern relevance of the teachings of Jesus, and an impassioned plea on the part of its author for an end to the folly of interpreting Christianity solely in “individualistic” terms. It is Rauschenbusch’s expressed aim to resurrect the core teachings of Jesus, which are social and ethical, and apply these to a renewed, socially conscious liberal democracy, establishing a grand harmony between religion, ethics, and social evolution. How far this vision was from the burgeoning “fundamentalism” of his day (and ours) is more than evidenced by the critical reaction of many of his more conservative peers, but also indicates the continuing relevance of his work for theologians and others looking for alternative paths. The following exposition is supplemented with appreciative and critical comments.

A Semiempirical Transition State Structure for the First Step in the Alkaline Hydrolysis of Cocaine. Comparison between the Transition State Structure, the Phosphonate Monoester Transition State Analog, and a Newly Designed Thiophosphonate Transition State Analog

Semiempirical molecular orbital calculations have been performed for the first step in the alkaline hydrolysis of the neutral benzoylester of cocaine. Successes, failures, and limitations of these calculations are reviewed. A PM3 calculated transition state structure is compared with the PM3 calculated structure for the hapten used to induce catalytic antibodies for the hydrolysis of cocaine. Implications of these calculations for the computer–aided design of transition state analogs for the induction of catalytic antibodies are discussed.

Montaigne, Lying and Early Modern Self-Fashioning: A Discursive Dialogue with Lope's El perro del hortelano on the Page and on Stage

A shared code of connection arguably exists between two plays by Lope de VegaEl mayordomo de la duquesa de Amalfi and El perro del hortelanoand the work of Michel de Montaigne. Nevertheless, one cannot but ask: how it can be that in two works produced so close in time, the same situation is resolved so differently? Montaigne can be said to provide an answer in his Essays, explaining that a similar situation can produce wholly different results: how in the first, one is saved', and in the second, one is destroyed. One might imagine, too, that Belflor's countess and her ennobled secretary, who together sustain a lie in a society that lived by the lie, would have been likewise consoled' by a set of interlocking tropes and similitudes' in the words of Stephen Greenblatt, which linked two contemporary and complementary fashioners of human nature, Lope and Montaigne, in a discursive dialogue on how otherwise honest women and men were subject to the vice of lying in their process of self-fashioning, as well as potentially enslaved' by it.

Testing the TICT State Hypothesis: an Investigation into the Solvatochromic Behavior of 2-Naphthalenylmethylene Malononitrile

Towards the goal of investigating the possible Twisted Intramolecular Charge Transfer (TICT) state mechanism of fluorescence emission, two aromatic dicyanovinyl compounds, 2-(naphthalene-2-ylmethylene) malononitrile (DCN) and a rigidified analogue, 3,4-dihydrophenanthren-1(2H)-ylidene)malononitrile (RDCN) were synthesized and their absorption and steady-state fluorescence emission spectra characterized. The spectral characterization was divided into two studies: first, DCN and RDCN were characterized in liquid solvents of increasing polarity; second, DCN and RDCN were characterized in viscous solvents and rigid glass media. The absorption spectra for both DCN and RDCN in all solvents demonstrated little to no solvatochromism. Emission results for DCN and RDCN in liquid solvents of increasing polarity showed DCN possessing strong solvatochromism while RDCN showed much less solvatochromism. Using the Lippert-Mataga equation, the difference between the ground and excited state dipole moment for DCN was estimated to be 8.4 + 0.4 Debye and between ~3.0 to 5.0 Debye for RDCN. Quantum yield measurements for DCN and RDCN in hexane, diethyl ether and acetonitrile were less than 0.01 and independent of polarity for both both solvents, with DCN generally possessing a quantum yield 3-4 times greater than RDCN. Experiments in glass media for DCN and RDCN showed a lessening of their solvatochromic character in both polar and non-polar glasses. These data provide strong evidence for a link between molecular flexibility and solvatochromism. However, while these data are consistent with a TICT state hypothesis for the emission mechanism, an alternative mechanism proposed by Maroncelli et al.10 involving rotation about the dicyanovinyl double bond in the excited state remains a possibility as well.

The Crystallization Kinetics of Polylactic Acid (Pla) Processed Through Solid-State/Melt Extrusion

Polylactic acid (PLA) is a bio-derived, biodegradable polymer with a number of similar mechanical properties to commodity plastics like polyethylene (PE) and polyethylene terephthalate (PETE). There has recently been a great interest in using PLA to replace these typical petroleum-derived polymers because of the developing trend to use more sustainable materials and technologies. However, PLA¿s inherent slow crystallization behavior is not compatible with prototypical polymer processing techniques such as molding and extrusion, and in turn inhibits its widespread use in industrial applications. In order to make PLA into a commercially-viable material, there is a need to process the material in such a way that its tendency to form crystals is enhanced. The industry standard for producing PLA products is via twin screw extrusion (TSE), where polymer pellets are fed into a heated extruder, mixed at a temperature above its melting temperature, and molded into a desired shape. A relatively novel processing technique called solid-state shear pulverization (SSSP) processes the polymer in the solid state so that nucleation sites can develop and fast crystallization can occur. SSSP has also been found to enhance the mechanical properties of a material, but its powder output form is undesirable in industry. A new process called solid-state/melt extrusion (SSME), developed at Bucknell University, combines the TSE and SSSP processes in one instrument. This technique has proven to produce moldable polymer products with increased mechanical strength. This thesis first investigated the effects of the TSE, SSSP, and SSME polymer processing techniques on PLA. The study seeks to determine the process that yields products with the most enhanced thermal and mechanical properties. For characterization, percent crystallinity, crystallization half time, storage modulus, softening temperature, degradation temperature and molecular weight were analyzed for all samples. Through these characterization techniques, it was observed that SSME-processed PLA had enhanced properties relative to TSE- and SSSP-processed PLA. Because of the previous findings, an optimization study for SSME-processed PLA was conducted where throughput and screw design were varied. The optimization study determined PLA processed with a low flow rate and a moderate screw design in an SSME process produced a polymer product with the largest increase in thermal properties and a high retention of polymer structure relative to TSE-, SSSP-, and all other SSME-processed PLA. It was concluded that the SSSP part of processing scissions polymer chains, creating defects within the material, while the TSE part of processing allows these defects to be mixed thoroughly throughout the sample. The study showed that a proper SSME setup allows for both the increase in nucleation sites within the polymer and sufficient mixing, which in turn leads to the development of a large amount of crystals in a short period of time.
