CO and CI maps of the starburst galaxy M82

The first map of an external galaxy in the 3P₁ - 3P0 fine-structure line of atomic carbon (CI) is presented towards the nucleus of the starbuster M82, and compared with the distinction of the CO J = 4 - 3 molecular emission. The CI traces features that are seen in lower transition CO maps, and shows that CI and the CO are well mixed and have similar spatial distributions. There are small differences between the CO J = 4 - 3 line and lower transition CO data towards the NE part of the molecular ring, where the emission is less prominent. The abundance ratio [CI]/[CO] across M82 is very high, with an average value ~ 0.5 across most of the nucleus, a factor at least 5 times that which is typical of dense molecular cloud cores seen in our own Galaxy. This means that on average, CI is overabundant towards M82. This result can be explained using models which provide enhancements to the CI abundance above normal Interstellar Medium values, a result of a greater cosmic ray flux in M82, or where there is substantial mixing of the gas

A Statutory Model for Corporate Constituency Concerns

The modern corporation by its nature creates interdependencies with a variety of groups with whom the corporation has a legitimate concern, such as employees, customers, suppliers, and members of the communities in which the corporation operates. Corporate governance involves a system of contractual and fiduciary duties that influence directors and officers to make decisions consistent with defined obligations. This system requires that directors consider shareholders\u27 interests first and foremost in making corporate decisions because the share-holders are the, owners, of the corporation. Over the past several decades, a number of states have implemented this policy by enacting constituency statutes. These statutes transform the obligations of corporate directors by expanding the groups to which boards of directors are accountable in decision making, greatly impacting the management decisions of business firms. Both legal and economic changes result from redefining the duties of corporate directors, ultimately transforming American business

Not If but How : Reflecting on the ABA Commission\u27s Recommendations on Multidisciplinary Practice

Multidisciplinary practice (MDP) has been aptly described as the, most important issue facing the legal profession today. The American Bar Association\u27s Commission on Multidisciplinary Practice (Commission) surprised most observers on June 8, 1999 by recommending that the American Bar Association (ABA) amend the Model Rules of Professional Conduct (Model Rules) to allow lawyers to combine with, and share fees with, other professionals within a single professional entity. Under the proposal, lawyers could create partnerships with accountants, developers, engineers, bankers, and all other professionals, thereby giving clients access to one-stop shopping at multidisciplinary firms
