Global Worldsheet Anomalies from M-Theory

We present an M-theory proof of the anomaly of Freed and Witten which in general shifts the quantisation law for the U(1) gauge field on a D6-brane. The derivation requires an understanding of how fields on the D6-brane lift to M-theory, together with a localisation formula which we prove using a U(1)-index theorem. We also show how the anomaly is related to the K-theory classification of Ramond-Ramond fields. In addition we discuss the M-theory origin of the D6-brane effective action, and illustrate the general arguments with a concrete example.Comment: 25 pages; v2: minor alterations, references added; v3: various arguments clarified, mathematical background added.

Can’t Buy Me Love

Critics of commodification often claim that the buying and selling of some good communicates disrespect or some other inappropriate attitude. Such semiotic critiques have been leveled against markets in sex, pornography, kidneys, surrogacy, blood, and many other things. Brennan and Jaworski (2015a) have recently argued that all such objections fail. They claim that the meaning of a market transaction is a highly contingent, socially constructed fact. If allowing a market for one of these goods can improve the supply, access or quality of the good, then instead of banning the market on semiotic grounds, they urge that we should revise our semiotics. In this reply, I isolate a part of the meaning of a market transaction that is not socially constructed: our market exchanges always express preferences. I then show how cogent semiotic critiques of some markets can be constructed on the basis of this fact

Buffalo City Comptroller

Under the Buffalo Charter and Code, the Comptroller is the head of the Department of Audit and Control. The Department of Audit and Control is broken down into three divisions: Division of Audit, Division of Accounting, and Division of Investment and Debt Management. The Division of Audit is headed by the City Auditor; the Division of Accounting is headed by the City Accountant, and the Division of Investment and Debt Management is headed by the Investment and Debt Management Officer. All heads are Deputies of the Comptroller who can be appointed and removed at the pleasure of the Comptroller. The City Auditor exercises all powers and duties with respect to audits and approves all checks signed by the Comptroller or the Comptroller’s Deputies. The City Accountant exercises all powers and duties with respect to accounts and accounting and prepares all checks.
