The rational classification of links of codimension >2
Fix an integer m and a multi-index p = (p_1, ..., p_r) of integers p_i < m-2.
The set of links of codimension > 2, with multi-index p, E(p, m), is the set of
smooth isotopy classes of smooth embeddings of the disjoint union of the
p_i-spheres into the m-sphere. Haefliger showed that E(p, m) is a finitely
generated abelian group with respect to embedded connected summation and
computed its rank in the case of knots, i.e. r=1. For r > 1 and for
restrictions on p the rank of this group can be computed using results of
Haefliger or Nezhinsky. Our main result determines the rank of the group E(p,
m) in general. In particular we determine precisely when E(p,m) is finite. We
also accomplish these tasks for framed links. Our proofs are based on the
Haefliger exact sequence for groups of links and the theory of Lie algebras.Comment: 16 page

The topology of Stein fillable manifolds in high dimensions II
We continue our study of contact structures on manifolds of dimension at
least five using complex surgery theory. We show that in each dimension 2q+1 >
3 there are 'maximal' almost contact manifolds to which there is a Stein
cobordism from any other (2q+1)-dimensional contact manifold. We show that the
product M x S^2 admits a weakly fillable contact structure provided M admits a
weak symplectic filling. We also study the connection between Stein fillability
and connected sums: we give examples of almost contact manifolds for which the
connected sum is Stein fillable, while the components are not.
Concerning obstructions to Stein fillings, we show that the
(8k-1)-dimensional sphere has an almost contact structure which is not Stein
fillable once k > 1. As a consequence we deduce that any highly connected
almost contact (8k-1)-manifold (with k > 1) admits an almost contact structure
which is not Stein fillable. The proofs rely on a new number-theoretic result
about Bernoulli numbers.Comment: We corrected mistakes in the proofs of Lemma 2.9 and Corollary 2.10.
This lead to an assumption being removed from the statement of Theorem 1.3.

Analysis of public relations factors involved in the reopening of the airport, Newark, New Jersey, November 15, 1952.
Thesis (M.S.)--Boston UniversitySince its establishment in 1929, the Newark Airport has played a major role in the development of air transportation and has contributed immensely to the economy of the areas adjacent to it in particular, and of the nation in general. Its sudden closure, brought about by a succession of tragic accidents, raised a controversial issue: that its present location constituted a serious hazard to the safety and security of the people of the neighboring cities and towns and, therefore, it must be closed permanently or moved to another location. The group that sought the Airport’s closure constituted a small minority. Regardless of their number, however, they successfully swayed public opinion to their side. But their victory was short-lived when the Airport was ordered re-opened, not-withstand their objections. The re-opening was ordered by the New York Port Authorities, operators of the Airport.

Naked Dishonesty: Misuse of a Social Security Number for an Otherwise Legal Purpose May Not Be a Crime Involving Moral Turpitude After All
This Comment questions whether the misuse of a Social Security number for an otherwise legal purpose is a crime involving moral turpitude. It begins with a history of moral turpitude and its initial connection to immigration law in the United States. Through a close analysis of misuse of a Social Security number for an otherwise legal purpose as a crime involving moral turpitude in modern cases, this Comment will examine the role of fraud and dishonesty in the question. The analysis reveals a critical distinction between crimes involving dishonesty and crimes involving fraud. This distinction shows that crimes involving naked dishonesty, that is, crimes that involve dishonesty but do not involve fraud, namely misuse of a Social Security number for an otherwise legal purpose, need not be classified as crimes involving moral turpitude under the law
CORPORATIONS, PARTNERSHIPS, AND ASSOCIATIONS Partnerships: Designate Qualification Requirements, Laws Governing, and Regulation Concerns for Foreign Limited Liability Partnerships
The Act provides guidelines for foreign limited liability partnerships transacting business in Georgia. The Act mandates certification with the Secretary of State as a means for providing service of process on foreign limited liability partnerships. Once a certificate is issued, a foreign limited liability partnership is authorized to transact business in Georgia. In addition, the Act requires appointment of a registered agent who may accept service of process on behalf of the foreign limited liability partnership. The Act also provides a list of activities that do not constitute transacting business in Georgia; however, the list is not intended to be exhaustive. Any foreign limited liability partnership that is not authorized to transact business in Georgia is also prohibited from maintaining any action, suit, or proceeding in a Georgia court

The Federal College Work-Study Program in the AAU Universities 1965-1975: Some Implications of Professional Discretion
This is a summary of a study of the Federal College v. Work-Study Program (CWSP) which was completed early in 1977. The purpose of the project was to analyze the implementation of the Work-Study program since 19fi5 by the 48 institutions which comprise the Association. of American Universities (AAU). The article addresses. the ways in which these 24 private and 24 public universities have established this student assistance policy and considers some of the implications for universities and particularly for graduate students
