  Explanation/Reference:

  What makes a rhinoceros look like a rhinoceros, or a petunia like a petunia? Understanding the basis of the generation of the forms, patterns, or shapes of complex organisms is a principal subject of biologist Gerald Edelman's stimulating book Topobiology, which explores the links among the development, evolution, form, and function of organisms. In older scientific language, one could say that Edelman has brought a new dimension to morphology, the study of the form and shape of animate and plants, and to histology, the study of the minute structure of tissues. The major thrust of his book te what he calls a morphoregulatory hypothesis, which can be described as the outline of a molecular basis for the formation of pattern, involving three types of genes. In the morphoregulatory sequence, morphoregulatory genes control the production of molecules that cause the formation of clusters of cells. When the cell dusters begin to communicate, they activate another type (selector genes) that then select and switch on a third type of gene (historegulatory genes). In the organisms they have studied, Edelman and his colleagues have found cell adhesion molecules (resulting from morphoregulatory gene action) that are attached to the surface of different cells and link them in clusters. These molecules can appear at different times in the development of a multicellular system, and at various specific sites on the cells. Furthermore, their chemical structure can vary. This tremendous variation allows a great flexibility in the kinds of linkages the molecules effect. A second class of adhesion molecules plays a comparable role In attaching cells to the developing scaffolding of filaments that lie outside cells. Also of particular interest to researchers are what are called cell Junction molecules, composed of clusters of proteins providing small channels from the inside of one cell to the Inside of another. These three types of molecules facilitate a kind of conversation among eels that determines the course of development of organisms. It has been possible to demonstrate how Important these molecules are by treating tissues with agents that block their functions, thus effectively and drastically changing the organism's development.

• Question 395:

  As discussed in the passage, smoothing production is primarily concerned with

  A. using the most efficient production processes available in order to avoid bottlenecks
  B. absorbing into overhead expenses the cost of holding inventory
  C. keeping production lines running continuously without interruption for maintenance
  D. assuring that there are as few peaks and valleys as possible in demand for the products made
  E. maintaining production levels as constant as is practicable
  D. assuring that there are as few peaks and valleys as possible in demand for the products made

  Explanation/Reference:

  According to the production-smoothing buffer stock model, inventories of a firm's products allow it to supply unexpected demand without having to adjust output immediately. When costs per additional unit produced are increasing, using inventory to smooth production is efficient as long as the savings from not adjusting production exceed the cost of holding inventory. Inventory acts as a buffer stock, absorbing increases or decreases in demand while production remains relatively steady. If firms are smoothing production, then sales should vary more than production. If inventories are used as a buffer stock, then high-frequency changes in inventory should be in the opposite direction to sales. Empirical research using aggregate data does not confirm this expectation, however; production varies more than sales, and changes in inventory and sales tend to vary in the same direction. Thus either the production-smoothing buffer stock model is incorrect, or other factors are preventing empirical confirmation of the smoothing effect. Most of the research that finds contradictions of production smoothing uses seasonally adjusted aggregate data concerning inventory and sales. It is possible that firms actually do use inventory to smooth production, but the research has failed to detect signs of this activity because the data are too highly aggregated over many firms. But even research at the level of individual companies has failed to confirm the model.

• Question 397:

  Journal

  The editor of Metathesis, a new academic journal of literature, manages the peer-review of articles submitted for publication. The journal accepts articles focusing on any of three general subject areas:

  comparative literature, modernist literature, and postcolonial literature.

  When an article is submitted, the editor has the article peer-reviewed by exactly three experts, none of whom authored or coauthored the article. The table (see the Reviewers/Authors tab) consists of all the authors or coauthors who have

  recently submitted articles and all the experts who currently peer-review or have recently peer- reviewed those articles. It also lists the general subject areas for each of the authors and reviewers.

  Each author of each submitted article specializes in the general subject area of the article. Moreover, each recently submitted article was peer-reviewed by experts listed in the table.
