The L-/C-band feed design for the DSS 14 70-meter antenna (Phobos mission)

A dual-frequency (1.668 and 5.01 GHz) feed was designed for the Deep Space Station (DSS) 14 70-m antenna to support the Soviet Phobos Mission. This antenna system was capable of supporting telemetry, two-way Doppler, and very long baseline interferometry (VLBI). VLBI and two-way Doppler information on the Phobos spacecraft was acquired with this antenna in 1989

The Effectiveness of State and Local Regulation of Handguns: A Statistical Analysis

One aspect of the continuing debate over weapons control, apart from Constitutional issues, is whether legislation is inherently capable of reducing crime and deaths by shooting. The opponents of increased control, tacitly admitting that empirical evidence is one means for measuring the effect of weapons regulation, have contended that [e]xpert opinion and compelling evidence seem to indicate that the amount or kind of crime in a community is not substantially affected by the relative ease with which a person can obtain a firearm. National Rifle Association of America, The Gun Law Problem 10. In the following study the authors employ data analysis techniques to examine the efficacy of state and municipal controls on handguns. They conclude that many lives would be saved if all states increased their level of control to that of New Jersey, the state having the most stringent gun control laws

In turn, birds differ in their relative fitness, in part as a consequence of movement and space use decisions. The saga of each individual plays out across time and space, generating the dynamic pattern known as a species' geographic range. Then, changes in geographic range dimensions alter the selective environment encountered by individuals, potentially driving evolutionary change in movement modes. Thus, understanding resource selection requires knowledge of both individual behavior and landscape patterns of patch occupancy. This thesis describes resource selection from both perspectives. We conducted two concurrent studies in a cooperatively breeding bird (Brown-headed Nuthatches, Sitta pusilla). We radio-tracked 22 Brown-headed Nuthatches, and related their space use to available resources within their respective home ranges. These associations controlled for the influence of the nest site as a central place; thus use of these resources reflected their perceived value to nuthatches. Areas of high use were associated with recently-killed trees, recent prescribed fire, pine dominance, and grassy herbaceous cover in descending order of importance. We also modeled patch occupancy across a range extension front created by habitat restoration. We found that high quality habitat near the range limit was vacant while marginal habitat was occupied, contrary to the standard model of range extension wherein habitats are occupied in order of quality. The pattern we observed is consistent with a range extension front that has been shaped by constraints on effective dispersal. This pattern may be quite common among birds given that many species are sedentary and that long-distance dispersers may have lower survival or fail to reproduce

Bail Practices in Allegheny County

The administration of bail involves two separate questions: (1) is the defendant eligible for bail; and (2) if he is eligible, what conditions of release should be imposed. The first question is readily answered by reference to federal and state constitutional and statutory provisions. Generally anyone charged with a non-capital offense is eligible for bail. The second question is not as easily resolved. Federal and state statutes set out only general considerations. Typical is Rule 46c of the Federal Rules of Criminal Procedure which provides that the amount of bail should be such as will insure the presence of the defendant, having regard to the circumstances of the offense charged, the weight of the evidence against him, the financial ability of the defendant to give bail and the character of the defendant. Relevant to the determination of conditions of release is the Eighth Amendment\u27s prohibition against excessive bail. There is, however, almost no case law construing this provision-even its applicability to state proceedings through the Fourteenth Amendment is unsettled

Education and Policy in the New Latino Diaspora

Increasing numbers of Latinos (many immigrant, and some from elsewhere in the United States) are settling both temporarily and permanently in areas of the United States that have not traditionally been home to Latinos-for example, North Carolina, Maine, Georgia, Indiana, Arkansas, rural Illinois, and near resort communities in Colorado.\u27 Enrique Murillo and Sofia Villenas have called this the New Latino Diaspora (Murillo and Vienas, 1997). Newcomer Latinos are confronted with novel challenges to their senses of identity, status, and community. Instead of arriving in settings, like the Southwest, where Latinos have lived for centuries, those in the New Latino Diaspora arrive in unfamiliar places where long-term residents have little experience with Latinos. In the New Diaspora, then, Latinos face more insistent questions about who they are, who they seek to be, and what accommodations they merit-questions that are asked both by themselves and by others
