ADAM SMITH'S OPTIMISTIC TELEOLOGICAL VIEW OF HISTORY
No full textAdam Smith's four-stage theory provides the framework for his writings on history. The fourth stage is the commercial epoch; the culmination of history in this stage is a key component in the conventional interpretation of Adam Smith as a prophet of commercialism. In two historical case studies Smith shows the capacity of commercial society to regenerate itself. This potent capacity suggests that commercial society is inevitable. At a certain point in time it also overcomes the major obstacles to its permanence. Smith's philosophy of history anticipates the end of history views of Kant and Hegel.Political Economy,
How Might Adam Smith Pay Professors Today?
No full textAdam Smith’s proposal for paying professors was intended to induce increased faculty knowledge. If students have imperfect information about what they learn, and universities can only imperfectly measure the input of faculty time in student learning, publications may be used to measure faculty knowledge. If professors’ ability to publish is positively related to their ability to produce student learning, which universities can imperfectly measure, publications may be necessary to attract more able professors. Since research signals faculty knowledge, schools that do not value publications per se could require higher publication standards and pay higher wages than schools that value only publications.
ADAM SMITH'S VIEW OF HISTORY: CONSISTENT OR PARADOXICAL?
No full textThe conventional interpretation of Adam Smith is that he is a prophet of commercialism. The liberal capitalist reading of Smith is consistent with the view that history culminates in commercial society. The first part of the article develops this optimistic interpretation of Smith's view of history. Smith implies that commercial society is the end of history because 1) it supplies the ends of nature that he identifies; 2) it is inevitable; and 3) it is permanent. The second part of the article shows that Smith has some dark moments in his writings where he seems to reject completely such teleological notions. In this more civic humanist mood he confesses that commercial society does not supply the ends of nature, nor is it inevitable, nor is it permanent. Both views exist in Smith and the commentator is forced to choose between passages in Smith's work in order to support a particular interpretation of the former's view of history.Political Economy,
A single amino acid distorts the Fc γ receptor IIIb/CD16b structure upon binding immunoglobulin G1 and reduces affinity relative to CD16a
No full textTherapeutic mAbs engage Fc γ receptor III (CD16) to elicit a protective cell-mediated response and destroy the target tissue. Newer drugs designed to bind CD16a with increased affinity surprisingly also elicit protective CD16b-mediated responses. However, it is unclear why IgG binds CD16a with more than 10-fold higher affinity than CD16b even though these receptors share more than 97% identity. Here we identified one residue, Gly-129, that contributes to the greater IgG binding affinity of CD16a. The CD16b variant D129G bound IgG1 Fc with 2-fold higher affinity than CD16a and with 90-fold higher affinity than the WT. Conversely, the binding affinity of CD16a-G129D was decreased 128-fold relative to WT CD16a and comparably to that of WT CD16b. The interaction of IgG1 Fc with CD16a, but not with CD16b, is known to be sensitive to the composition of the asparagine-linked carbohydrates (N-glycans) attached to the receptor. CD16a and CD16b-D129G displaying minimally processed oligomannose N-glycans bound to IgG1 Fc with about 5.2-fold increased affinity compared with variants with highly processed complex-type N-glycans. CD16b and the CD16a-G129D variant exhibited a smaller 1.9-fold affinity increase with oligomannose N-glycans. A model of glycosylated CD16b bound to IgG1 Fc determined to 2.2 Å resolution combined with a 250-ns all-atom molecular dynamics simulation showed that the larger Asp-129 residue deformed the Fc-binding surface. These results reveal how Asp-129 in CD16b affects its binding affinity for IgG1 Fc and suggest that antibodies engineered to engage CD16b with high affinity must accommodate the Asp-129 side chain.This research was originally published in the Journal of Biological Chemistry.

CD16a with oligomannose-type N-glycans is the only “low-affinity” Fc γ receptor that binds the IgG crystallizable fragment with high affinity in vitro
No full textFc γ receptors (FcγRs) bind circulating IgG (IgG1) at the surface of leukocytes. Antibodies clustered at the surface of a targeted particle trigger a protective immune response through activating FcγRs. Three recent reports indicate that the composition of the asparagine-linked carbohydrate chains (N-glycans) of FcγRIIIa/CD16a impacted IgG1-binding affinity. Here we determined how N-glycan composition affected the affinity of the “low-affinity” FcγRs for six homogeneous IgG1 Fc N-glycoforms (G0, G0F, G2, G2F, A2G2, and A2G2F). Surprisingly, CD16a with oligomannose N-glycans bound to IgG1 Fc (A2G2) with a KD = 1.0 ± 0.1 nM. This affinity represents a 51-fold increase over the affinity measured for CD16a with complex-type N-glycans (51 ± 8 nM) and is comparable with the affinity of FcγRI/CD64, the sole “high-affinity” FcγR. CD16a N-glycan composition accounted for increases in binding affinity for the other IgG1 Fc glycoforms tested (10–50-fold). This remarkable sensitivity could only be eliminated by preventing glycosylation at Asn162 with an Asn-to-Gln mutation; mutations at the four other N-glycosylation sites preserved tighter binding in the Man5 glycoform. None of the other low-affinity FcγRs showed more than a 3.1-fold increase upon modifying the receptor N-glycan composition, including CD16b, which differs from CD16a by only four amino acid residues. This result indicates that CD16a is unique among the low-affinity FcγRs, and modifying only the glycan composition of both the IgG1 Fc ligand and receptor provides a 400-fold range in affinities.This research was originally published in the Journal of Biological Chemistry.

Adam Smith and Roman Servitudes
No full textThis essay is a preprint of an article that appeared at: Tijdschrift voor Rechstsgeschiedenis, 72 (2004), 327–57.This essay discusses Adam Smith historical jurisprudence and his use of Roman law materials in his Lectures on Jurisprudence. It argues that Smith found it difficult to maintain his theory of legal development in the face of a highly developed body of Roman law literature
THE THEOLOGICAL FOUNDATION OF ADAM SMITH'S WORK
No full textThe paper will discuss the theological foundation to Smith's writings. Teleology, final causes and divine design were initially seen as central to understanding Smith's writings. Over time, this view fell out of fashion. In the period after World War II, with the rise of positivism, commentators tended to overlook or downplay this interpretation. In the last decade, or so, teleology has started to be restored to its former position as an essential element in understanding Smith. After spelling out Smith's teleology and his view of final causes, divine design and the ends of nature, we try to explain the Panglossian nature of the 'new theistic view' of Smith. While our view differs somewhat, we agree with the essence of the 'new view' claim: a theological view exists in Smith which underpins his moral and economic theories.Political Economy,

Książę Adam Jerzy Czartoryski i jego stronnicy w świetle historiografii ukraińskiej
No full textIn 1937, the Warsaw historian Marceli Handelsman published a work entitled Ukraińska polityka
ks. Adama Czartoryskiego przed wojną krymską [Ukrainian politics of Prince Adam Czartoryski
before the Crimean War]. So far, this book has been used by historians as the primary source of
information on the Ukrainian issue in the views of the Hotel Lambert’s leader. The author of this
text has decided to collect Ukrainian works referring to the topic inaugurated by Handelsman. Unfortunately, no larger study has been prepared on the Ukrainian side. However, a number of articles
and encyclopaedic notes showing Prince Adam and his Eastern policy (especially during his stay
at the court of Tsar Alexander I Romanov) has been published. Ukrainian authors paid much more
attention to Czartoryski’s associates, who tried to put his ideas into practice. Ukrainian researchers
wrote mainly about Michał Czaykowski (Sadyk Pasha) organizing the Cossack troops in the Ottoman Empire, about Hipolit Terlecki striving for the union of the Orthodox and Roman Catholic
Churches, and finally about the ethnographer and writer Franciszek Duchiński clearly separating
Ukraine from Russia in his writings
