Lobbying, political competition, and local land supply: recent evidence from Spain

We analyze whether local land supply is influenced by the degree of political competition, and interpret the findings as being indicative of the influence wielded by land development lobbies. We use a new database including both political and land supply data for more than 2,000 Spanish municipalities for the period 2003-2007. In Spain, land use policies are largely a local responsibility with municipalities having periodically to pass compre- hensive land use plans. The main policy variable in these plans, and the one analyzed here, is the amount of land classified for potential development. We measure local political competition as the margin of victory of the incumbent government. We instrument this variable using the number of votes obtained by parties represented in local government when standing at the first national legislative elections following the re-establishment of democracy, and the number of votes they actually obtained regionally at the national legislative elections. The results indicate that stiffer political competition does indeed reduce the amount of new land designated for development. This effect is found to be most marked in suburbs, in towns with a high percent of commuters and homeowners, and in municipalities governed by the left.

Executive Order Number Seventy One, March, 2011

The act new policies that encourage a job-friendly environment can take Iowa a significant way forward in our effort to compete for new jobs, much of that work can be undone by a bureaucracy that fails to understand the critical relationship between burdensome regulation and job creation

Stable one-step technetium-99m labeling of His-tagged recombinant proteins with a novel Tc(I)-carbonyl complex.

We have developed a technetium labeling technology based on a new organometallic chemistry, which involves simple mixing of the novel reagent, a 99m Tc(I)-carbonyl compound, with a His-tagged recombinant protein. This method obviates the labeling of unpaired engineered cysteines, which frequently create problems in large-scale expression and storage of disulfide-containing proteins. In this study, we labeled antibody single-chain Fv fragments to high specific activities (90 mCi/mg), and the label was very stable to serum and all other challenges tested. The pharmacokinetic characteristics were indistinguishable from iodinated scFv fragments, and thus scFV fragments labeled by the new method will be suitable for biodistribution studies. This novel labeling method should be applicable not only to diagnostic imaging with 99mTc, but also to radioimmunotherapy approaches with 186/188 Re, and its use can be easily extended to almost any recombinant protein or synthetic peptide.

One hundred topics in Iowa history, 1914.

Dr. Dan Elbert Clark compiled and Benjamin F. Shambaugh edited this edition of a list of Iowa history topics, which originally was suggested by Miss Alice Tyler, Secretary of the Iowa Library Commission in 1907. It is also called Bulletin of Information Series, no. 7 published by the State Historical Society of Iowa. The subjects presented will give the reader a general knowledge of the more important facts and phases of Iowa's commonwealth history. Also included in this document are lists of authors of the articles sited, suggested courses of study or reading in Iowa history, the Governor's of Iowa, United State Senators from Iowa and a list of some of the important dates in early Iowa history.

One hundred base pairs of 5' flanking sequence of a vaccinia virus late gene are sufficient to temporally regulate late transcription.

A vaccinia virus late gene coding for a major structural polypeptide of 11 kDa was sequenced. Although the 5' flanking gene region is very A+T rich, it shows little homology either to the corresponding region of vaccinia early genes or to consensus sequences characteristic of most eukaryotic genes. Three DNA fragments (100, 200, and 500 base pairs, respectively), derived from the flanking region and including the late gene mRNA start site, were inserted into the coding sequence of the vaccinia virus thymidine kinase (TK) early gene by homologous in vivo recombination. Recombinants were selected on the basis of their TK- phenotype. Cells were infected with the recombinant viruses and RNA was isolated at 1-hr intervals. Transcripts initiating either from the TK early promoter, or from the late gene promoter at its authentic position, or from the translocated late gene promoters within the early gene were detected by nuclease S1 mapping. Early after infection, only transcripts from the TK early promoter were detected. Later in infection, however, transcripts were also initiated from the translocated late promoters. This RNA appeared at the same time and in similar quantities as the RNA from the late promoter at its authentic position. No quantitative differences in promoter efficiency between the 100-, 200-, and 500-base-pair insertions were observed. We conclude that all necessary signals for correct regulation of late-gene expression reside within only 100 base pairs of 5' flanking sequence.

Effective one-dimensional square well for two-dimensional quantum wires

The symmetrical two-dimensional quantum wire with two straight leads joined to an arbitrarily shaped interior cavity is studied with emphasis on the single-mode approximation. It is found that for both transmission and bound-state problems the solution is equivalent to that for an energy-dependent one-dimensional square well. Quantum wires with a circular bend, and with single and double right-angle bends, are examined as examples. We also indicate a possible way to detect bound states in a double bend based on the experimental setup of Wu et al.

Design of electron band pass filters for electrically biased finite superlattices

We design optimal band pass filters for electrons in semiconductor heterostructures, under a uniform applied electric field. The inner cells are chosen to provide a desired transmission window. The outer cells are then designed to transform purely incoming or outgoing waves into Bloch states of the inner cells. The transfer matrix is interpreted as a conformal mapping in the complex plane, which allows us to write constraints on the outer cell parameters, from which physically useful values can be obtained.

One Unshakable Vision: World Class Schools for Iowa, October 3, 2011

Iowans have long shared a deep commitment to giving our children the best education possible. We recognize young people today must meet higher expectations than ever to thrive in this global, knowledge-based economy. For the sake of our children and our state, it is vitally important that we build on our tradition of excellence to improve our schools. Iowa’s house of education still has a strong foundation, but it is also in need of a major remodel to be ready for the days ahead.
