Pelagic Cnidaria of Mississippi Sound and Adjacent Waters

Investigations were made in Mississippi Sound and adjacent waters from March 1968 through March 197 1 to record the occurrence and seasonality of planktonic cnidarians. About 700 plankton samples were taken from estuarine and oceanic areas. From these samples, 26 species of hydromedusae were identified, 12 of which were collected from Mississippi Sound. In addition, 25 species of siphonophorae were identified from Mississippi waters, although only 6 species were collected in Mississippi Sound. From an examination of about 500 trawl samples taken during this period, 10 species of Scyphozoa were found in Mississippi waters, 6 of which occurred in Mississippi Sound

Biology and Distribution of the Macrocoelenterates of Mississippi Sound and Adjacent Waters

Studies conducted in Mississippi Sound from April 1971 through June 1973 elucidated the seasonal and areal distribution of seven species of macrocoelenterates: Aurelia aurita (L), Chrysaora quinquecirrhu (Desor 1848), Pelagia noctiluca Forskål 1775, Chiropsalmus quadrumantus (Miiller 1859), Rhopilema verrillii (Fewkes 1887), Stomolophus meleagris L. Agassiz 1862, and Physalia physalis (L). Physical parameters presumed relevant to the distribution of each of these animals are presented. Developmental histories of certain of these forms are described

Notes on the Status of the Gannet (Morus bassanus) in the Gulf of Mexico, with a Record from Mississippi

The Northern Gannet nests on rock cliffs in the north Atlantic and winters as far south as Yucatan on the west, and N.W. Africa on the east. The birds are not known to cross land and seem to fly around Florida to enter the Gulf of Mexico. Most numbers have been reported off Louisiana, Mississippi, Alabama and the Florida panhandle. Numbers in the western Gulf seem to be few. There are 12 skeletal parts or skins of Texas gannets in museums in Texas and Louisiana. Two specimens have been collected in Louisiana, only one of which is known to remain. There are 6 specimens from the Mississippi coast (one from the high seas) in Mississippi and Louisiana museums, none from Alabama and 10 from south Florida. Gannets have been reported previously from the Gulf in every month but August. A live specimen was taken in Mississippi Sound on August 10, 1977 following heavy squalls. It was immature. It died on the same day. The skin was deposited in The Fannye A. Cook Memorial, the Mississippi Museum of Natural History, cataloged as Ab 5019

Loose Ends for the Exomoon Candidate Host Kepler-1625b

The claim of an exomoon candidate in the Kepler-1625b system has generated substantial discussion regarding possible alternative explanations for the purported signal. In this work we examine in detail these possibilities. First, the effect of more flexible trend models is explored and we show that sufficiently flexible models are capable of attenuating the signal, although this is an expected byproduct of invoking such models. We also explore trend models using X and Y centroid positions and show that there is no data-driven impetus to adopt such models over temporal ones. We quantify the probability that the 500 ppm moon-like dip could be caused by a Neptune-sized transiting planet to be < 0.75%. We show that neither autocorrelation, Gaussian processes nor a Lomb-Scargle periodogram are able to recover a stellar rotation period, demonstrating that K1625 is a quiet star with periodic behavior < 200 ppm. Through injection and recovery tests, we find that the star does not exhibit a tendency to introduce false-positive dip-like features above that of pure Gaussian noise. Finally, we address a recent re-analysis by Kreidberg et al (2019) and show that the difference in conclusions is not from differing systematics models but rather the reduction itself. We show that their reduction exhibits i) slightly higher intra-orbit and post-fit residual scatter, ii) $\simeq$ 900 ppm larger flux offset at the visit change, iii) $\simeq$ 2 times larger Y-centroid variations, and iv) $\simeq$ 3.5 times stronger flux-centroid correlation coefficient than the original analysis. These points could be explained by larger systematics in their reduction, potentially impacting their conclusions.Comment: 21 pages, 4 tables, 11 figures.

Hazing in Student Organizations: Prevalence, Attitudes, and Solutions

This article reports the results of a survey exploring hazing in student organizations. First, a typology of hazing behaviors was constructed through factor analysis. Second, respondents reported the prevalence of hazing, and results were compared across type of student organization. Third, respondents indicated their attitudes about hazing, and results were compared between perpetrators of hazing and their victims. Finally, respondents assessed the efficacy of various solutions to hazing, and results were compared between those who had perpetrated acts of hazing and those who had not. The results were used to construct a theoretical model of hazing behavior on college campuses, with recommendations for solutions
