PALEONTOLOGY, PALEOGEOGRAPHY, PALEOENVIRONMENT OF THE CAMPANIAN NEOGENE TETHYAN FORAMINIFERAL GENERA AND SPECIES OF ANAN A- SUBORDERS TEXTULARIINA AND MILIOLINA
No full textDuring the last four decades ago, fifty-seven (54 agglutinated and 3 porcelaneous) benthic foraminiferal species and related to 23 genera have been erected by the present author, which start at 1984, which are recoded from many countries around the Arabia (Egypt, Palestine, Jordan, Iraq, UAE, Iran and Pakistan), and also Saudi Arabia, Yemen, UAE and Qatar. Some of these species were also recorded from many countries in the Northern Tethys (Atlantic Ocean, USA, Spain, France and Poland), and western Pacific Ocean. These species help, not only to define the major faunal changes throughout the Campanian-Neogene time, but also to emphasis the stratigraphic importance of them in different localities in the Tethys. Most of the identified species were erected: 12 species (from Egypt), 11 (UAE), 8 (Iraq), 4 (Iran), 3 (Pakistan and France), 2 (Palestine, Pakistan, Spain and Poland), while one species only from the other countries. The Tethys assemblage indicates an open marine environment, which represents middle-outer neritic environment and shows an affinity with Midway-Type Fauna (MTF)
Differences between Doppler velocities of ions and neutral atoms in a solar prominence
No full textThis is the author accepted manuscript. The final version is available from EDP Sciences via the DOI in this record.Context. In astrophysical systems with partially ionized plasma the motion of ions is governed by the magnetic field while the neutral
particles can only feel the magnetic field’s Lorentz force indirectly through collisions with ions. The drift in the velocity between
ionized and neutral species plays a key role in modifying important physical processes like magnetic reconnection, damping of
magnetohydrodynamic waves, transport of angular momentum in plasma through the magnetic field, and heating.
Aims. This paper investigates the differences between Doppler velocities of calcium ions and neutral hydrogen in a solar prominence
to look for velocity differences between the neutral and ionized species.
Methods. We simultaneously observed spectra of a prominence over an active region in H I 397 nm, H I 434 nm, Ca II 397 nm, and
Ca II 854 nm using a high dispersion spectrograph of the Domeless Solar Telescope at Hida observatory, and compared the Doppler
velocities, derived from the shift of the peak of the spectral lines presumably emitted from optically-thin plasma.
Results. There are instances when the difference in velocities between neutral atoms and ions is significant, e.g. 1433 events (∼ 3 %
of sets of compared profiles) with a difference in velocity between neutral hydrogen atoms and calcium ions greater than 3σ of the
measurement error. However, we also found significant differences between the Doppler velocities of two spectral lines emitted from
the same species, and the probability density functions of velocity difference between the same species is not significantly different
from those between neutral atoms and ions.
Conclusions. We interpreted the difference of Doppler velocities as a result of motions of different components in the prominence
along the line of sight, rather than the decoupling of neutral atoms from plasma.This work was supported by a Grant-in-Aid for Scientific

The inflation in Western African countries between 1970 - 1982, 1985
No full textFor the last two decades, worldwide inflation had a very large impact on developing countries. While the rate of inflation slowed down in developed countries, increasing rate of inflation in Western African countries was almost doubled in the 1970s. The controversy over the increases in price level was between two groups of economistsstructuralist and monetarist. The monetarist points out that inflation can not be substajned without a continued expansion of money supply. But the structuralist argues that in developing countries, the causes of inflation maybe factors other than money supply. Some of these factors are the stagnation of food supply, inelasticity and instability of the purchasing power of export or bottlenecks in the supply of social over head capital and skilled labor. The objective of this study is to empirically estimate the relative impacts of various identified sources of inflation in selected Western African countries. By using the ordinary least squares procedures, results show that the nonetarist variables are more significant in explaining the estimated inflation rate of West Africa than the struc turaljst variables. In effect, we can conclude that the large quantity of money in peoples hands, without a corresponding quantity of goods to buy, led to the inflation. Structural variables may have a very important role, but the results of this study did not sufficiently bring out this role
Cibicidoides vulgaris

Campus Sexual Assault Prevention: Supporting Male Student Allies in an Effort to Sustain Engagement
No full textMovements to engage college men as activists and allies working to end sexual assault have become increasingly prevalent in U.S. colleges (Barone, Wolgemuth, & Linder, 2007; Berkowitz, 1994, 2002, 2004; Fabiano, Perkins, Berkowitz, Linkenbach, & Stark, 2003). Unfortunately, studies have shown that college men who are involved in breaking down gender norms and working to end sexual assault face being ostracized by their peers (Antill, 1987; Archer, 1984; Barone, Wolgemuth, & Linder, 2007, McCreary, 1994). The author will make an argument elucidating the importance for student affairs practitioners to foster an environment that is supportive of men who do not subscribe to hegemonic masculine ideals to keep them involved in the struggle to eliminate sexual assault as a reality

The Dead Eye and the Deep Blue Sea: An Illustration of the Illegal Fishing Economy
No full textThe blue economy needs to address labour abuse at sea.
In this short article I will provide a few insights into sea
narratives about labour abuse from a global perspective.
First, I will set out a few points on the global fishing economy
and ocean management. I will then discuss the experience
of labour abuse by using the graphic memoir of modern
slavery The Dead Eye and the Deep Blue Sea by Cambodian
author Vannak Anan Prum.The memoir is an example of
how narratives can recount the problems in the global fishing
economy and its links to individual experiences of abuse at sea
Dois corações simples: uma leitura de Mário de Andrade e Jean Paul
No full textAo chamar de “idílio” sua obra Amar, verbo intransitivo (1927), Mário de Andrade propôs um enigma para leitores e críticos a respeito do significado do termo e suas consequências para o texto. Tendo em vista as inúmeras referências à literatura e à cultura clássica alemãs e seu caráter estruturante dentro da narrativa, é possível analisar a hipótese de que Andrade se valia da definição de Jean Paul (1763-1825) para o idílio, tal como apresentada em sua Vorschule der Ästhetik (1804) e em Leben des vergnügten Schulmeisterlein Maria Wutz in Auental (1793), outra narrativa sobre um professor denominada “idílio”. Desse modo, tanto Fräulein Elza quanto Maria Wutz seriam protagonistas de um romance lírico que retrata um estado de plenitude, percebido apenas em função da distância tomada por um narrador capaz de descrever os limites externos de sua existência.By calling “idyll” his work Fräulein Elza (1927), brazilian modernist author Mário de Andrade made a riddle for readers and critics about the meaning of the word and its consequences for the text. In view of the numerous references to the German classical literature and culture and their structural role within the narrative, it is possible to analyze the hipothesis that Andrade refered to Jean Paul’s (1763-1825) definition of an idyll, as presented in his Vorschule der Ästhetik (1804) and in Leben des vergnügten Schulmeisterlein Maria Wutz in Auental (1793), another narrative about a teacher described as an “idyll”. Therefore, Fräulein Elza as well as Maria Wutz would be the protagonists of a lyrical novel that portrays a state of fulfillment that it is perceived only by a narrator capable of describing the external limits of their existence
