    Charm Decays and Spectroscopy at BABAR

    We present searches for rare charm decays of the form Xc+→h±ℓ∓ℓ(′)+X_c^+ \to h^{\pm} \ell^{\mp} \ell^{(')^+}, where Xc+X_c^+ is a charm hadron either D+D^+, Ds+D_s^+, or Λc+\Lambda_c^+, and ℓ(′)±\ell^{(')^{\pm}} is an electron or muon. These modes are based on 384 fb−1fb^{-1} of e+e−e^+ e^- annihilation data collected at the Υ(4S)\Upsilon(4S) resonance with the BABAR detector at the SLAC National Accelerator Laboratory. We also present the flavor-changing neutral-current decays D0→e+e−D^0 \to e^+e^-, D0→μ+μ−D^0 \to \mu^+ \mu^-, and D0→e±μ∓D^0 \to e^{\pm} \mu^{\mp} that corresponds to an integrated luminosity of 468 fb−1fb^{-1} of data. The decay D0→e+μ−D^0 \to e^+ \mu^- is further lepton-flavor violating, and thus occur only through very slow neutrino mixing. These decays constitute sensitive probes for possible new-physics contribution. We report new limits on the branching fractions of these decays.Comment: Contributed to the Proceedings of 36th International Conference on High Energy Physics, July 4-11, 2012, Melbourne, Australia.

    Jumping bristletail (Insecta: Apterygota: Microcoryphia) records in the southeastern United States

    Get PDF
    Few records of Microcoryphia exist for the southeastern United States, with named species being reported only from Arkansas, Tennessee, and the mid-Atlantic states, and with an unnamed species being reported from Georgia. Records are here provided from 291 specimens housed in the Mississippi Entomological Museum, including ten new species-level state records. This is also the first published report of the order Microcoryphia from Alabama and Mississippi. Species include the machilids Pedetontoides atlanticus Mendes in Alabama, Arkansas, Georgia, Mississippi, and North Carolina; Pedetontus cf. atlanticus in Kentucky; Pedetontus (Verhoeffilis) gershneri Allen in Arkansas; and Pedetontus (Pedetontus) saltator Wygodzinsky and Schmidt in Mississippi and North Carolina; and the meinertellid Machiloides banksi (Silvestri) in Alabama, Arkansas, Mississippi, and North Carolina

    Learned Treatises as Direct Evidence: The Alabama Experience

    Get PDF
    A majority of American jurisdictions refuse to permit the use of learned treatises as direct evidence, reasoning that to do so would violate the rule against hearsay evidence. However, many commentators have contended that, in adopting such a position, these courts have failed to consider the underlying purposes of the hearsay rule. Alabama, which has permitted the introduction of treatises as direct evidence, affords a useful contrast for testing both the rationale of the majority rule and the criticisms of it. It has been the goal of this comment to evaluate the present majority view against the Alabama experience. On the basis of the responses of Alabama attorneys, the conclusion is that the admission of learned treatises as direct evidence would be a desirable modificacation of the present rules of evidence

    ASSESSING THE INTERESTS OF WHOLESALE-PRODUCEBUYERS IN THE LOWER MISSISSIPPI DELTA REGION

    Get PDF
    The need to expand the market share of Alabama fruits and vegetable producers necessitates an understanding of the attributes that would attract potential wholesale-produce buyers in the Lower Mississippi Delta Region (LMDR). A survey was developed and administered to over three thousand produce wholesale buyers in the LMDR; 317 returned surveys were analyzed for this study. Results indicate that non-Alabama wholesale-produce buyers would buy Alabama produce if the produce meet expected quality if adequate volume existed, if it were convenient, and if they were aware that the produce existed in Alabama. Produce such as peaches, sweet corn, beans, potatoes, and watermelons have greater market potential if volume is adequate and price competitive.Agribusiness,

    Race, class, and community in a southern forest-dependent region

    Based on a Community and Environment in Rural America survey, this brief looks at four counties in Alabama. It finds blacks and whites have different outcomes in the community, despite expectations of regional stability and greater equality. Though they reported similar rates of social mobility, African Americans in the Black Belt of Alabama are disproportionately poorer and employed in lower-skill jobs than whites

    Overcoming Challenges of Teaching Earth History Classes for Teachers in a Rock-free, Urban Environment

    Get PDF
    Instructing university-level Earth history to future teachers is made all the more difficult when it is being done in an urban environment devoid of any local rock outcroppings. At the University of South Alabama, which is located along the rock-free central Gulf Coast, researchers have attempted to improve Earth history instruction to education majors. This paper describes their approach. The authors outline how they encouraged science composite education majors to think locally in order to better relate the world of geology to their students in the Alabama school system. They conclude with a brief discussion about the importance of providing field exposure to the teachers. Though this paper focuses on a local solution suitable for southwestern Alabama, the approach is easily exportable to institutions in other urbanized or rock-free parts of the world where similar problems doubtless occur.

    Use of data from space for earth resources exploration and management in Alabama

    Get PDF
    The University of Alabama, the Geological Survey of Alabama, and the George C. Marshall Space Flight Center are involved in an interagency, interdisciplinary effort to use remotely sensed, multispectral observations to yield improved and timely assessment of earth resources and environmental quality in Alabama. It is the goal of this effort to interpret these data and provide them in a format which is meaningful to and readily usable by agencies, industries, and individuals who are potential users throughout the State
