The relative stabilities of the reverse and normal polarity states of the earth's magnetic field

Recent analyses of the geomagnetic reversal sequence have led to different conclusions regarding the important question of whether there is a discernible difference between the properties of the two polarity states. The main differences between the two most recent studies are the statistical analyses and the possibility of an additional 57 reversal events in the Cenozoic. These additional events occur predominantly during reverse polarity time, but it is unlikely that all of them represent true reversal events. Nevertheless the question of the relative stabilities of the polarity states is examined in detail, both for the case when all 57 "events" are included in the reversal chronology and when they are all excluded. It is found that there is not a discernible difference between the stabilities of the two polarity states in either case. Inclusion of these short events does, however, change the structure of the non-stationarity in reversal rate, but still allows a smooth non-stationarity. Only 7 of the 57 short events are pre-38 Ma, but the evidence suggests that this is a real geomagnetic phenomenon rather than degradation of the magnetic recording or a bias in observation. This could be tested by detailed magnetostratigraphic and oceanic magnetic surveys of the Paleogene and Late Cretaceous. Overall it would appear that the present geomagnetic polarity timescale for 0–160 Ma is probably a very good representation of the actual history, and that different timescales and additional events now represent only changes in detail

Recruiting International Students to Your Campus

The purpose of this paper was to determine what institutional, program, and recruitment characteristics influenced international students to attend institutions in the United States. Two hundred sixteen international students at a Southern public research university responded to the survey (53% response rate) from 56 countries representing 8 regions. An empirical analysis using t-tests and analysis of variance was conducted to determine what characteristics international students found to be most important when selecting an institution. Regardless of degree level, all students ranked faculty/student ratio as an important program characteristic. Second, students ranked both the admission process and time to degree as important characteristics. Third, doctoral, master’s, and bachelor’s students respectively ranked funding as an important characteristic in their decision making process. There are three basic implications for recruitment officers. First, as size matters, international students need to feel connected to faculty and staff

The 1990 update to strategy for exploration of the inner planets

The Committee on Planetary and Lunar Exploration (COMPLEX) has undertaken to review and revise the 1978 report Strategy for Exploration of the Inner Planets, 1977-1987. The committee has found the 1978 report to be generally still pertinent. COMPLEX therefore issues its new report in the form of an update. The committee reaffirms the basic objectives for exploration of the planets: to determine the present state of the planets and their satellites, to understand the processes active now and at the origin of the solar system, and to understand planetary evolution, including appearance of life and its relation to the chemical history of the solar system

The Eco-Martyrs of 2018 and Maslow: Is Self-Actualization Only for Colonizers?

The Eco-Martyrs of 2018 and Maslow: Is Self-Actualization Only for Colonizers? Johanna Guz-Montgomery, Dept. of Psychology, Ian McFadden, Victoria Bee, Ashley Sanico, William Purrington, Christopher Latourrette, Rachel Creed, Kelly Rios-Santos, and Alan Lankford, with Dr. Richard Bargdill, Dept. of Psychology Every year the Global Witness organization complies and releases a list of forest, earth, water and animal protectors who have been murdered while defending the earth and people. There have been about 2000 “eco-martyrs” since 2002. Most of these persons are farmers, indigenous people, nature lovers or in other words--ordinary people. In their efforts to stop projects that would lead to further environmental destructive and increased climate change, these persons have stood up to governments, militaries, corporations which have attempted to intimidate them. Most of our ‘eco-martyrs’ had been previously threatened with violence and murder. Many have sought protection from authorities, although almost none have received any and if they did it was clearly ineffective. Our undergraduate research group lead by Dr. Richard Bargdill has constructed short summaries on each of the 2000 names over the last 3 years. We have been humbled by the courage and tenacity of this group of people who in the end represent the best that humanity has to offer. Yet, we noticed that according to our understanding of the Hierarchy of Needs put forth by Maslow that many of these eco-martyrs would not qualify as self-actualized since most live in nations that do not provide the lower needs. Last year we found exemplary cases from our eco-martyrs where from their brief biographies we could be certain that they exhibited at least one of the 16 qualities and did that for 16 cases. At a poster session we were approached by Maslow scholar Andrew Bland and given the suggestion that our understanding of Maslow’s Hierarchy of Needs was not complete. For this year’s presentation we would like to both address Dr. Bland’s constructive criticism and also share 16 eco-martyrs stories all of which were murdered in the 2018.https://scholarscompass.vcu.edu/uresposters/1375/thumbnail.jp

Protective effect of small molecule analogues of the Acanthocheilonema viteae secreted product ES-62 on oxazolone-induced ear inflammation

ES-62 is the major secreted protein of the rodent filarial nematode Acanthocheilonema viteae. The molecule contains covalently attached phosphorylcholine (PC) residues, which confer anti-inflammatory properties on ES-62, underpinning the idea that drugs based on this active moiety may have therapeutic potential in human diseases associated with aberrant inflammation. Here we demonstrate that two synthetic small molecule analogues (SMAs) of ES-62 termed SMA 11a and SMA 12b are protective in the oxazolone-induced acute allergic contact dermatitis mouse model of skin inflammation, as measured by a significant reduction in ear inflammation following their administration before oxazolone sensitisation and before oxazolone challenge. Furthermore, it was found that when tested, 12b was effective at reducing ear swelling even when first administered before challenge. Histological analysis of the ears showed elevated cellular infiltration and collagen deposition in oxazolone-treated mice both of which were reduced by treatment with the two SMAs. Likewise, the oxazolone-induced increase in IFNγ mRNA in the ears was reduced but no effect on other cytokines investigated was observed. Finally, no influence on the mast cell populations in the ear was observed
