Beta and omega[ edit ] Social animals in a hierarchic community are sometimes assigned ranks in ethology studies. Beta animals often act as second-in-command to the reigning alpha or alphas and will act as new alpha animals if an alpha dies or is otherwise no longer considered an alpha. In some species of birds, males pair up in twos when courting, the beta male aiding the alpha male. It has been found that the social context of the animals has a significant impact on courtship behavior and the overall reproductive success of that animal. Omega animals are subordinate to all others in the community, and are expected by others in the group to remain submissive to everyone. Omega animals may also be used as communal scapegoats or outlets for frustration, or given the lowest priority when distributing food. Alpha males who solely use intimidation and aggression to keep their position often provoke dissent. Coalitions will eventually form, which at some point will topple the alpha male. Males will associate with females for rank acquisition because females dominate the social environment.

Volatile-Rich Planet Loading the player MESSENGER measurements have revealed that Mercury is surprisingly abundant in volatile elements that evaporate at moderately high temperatures, ruling out many of the models for its formation and early history that had been proposed before the mission. Because potassium is much more volatile than thorium, the ratio of the abundances of these two elements is a sensitive measure of thermal processes that fractionate elements by volatility.
For Mercury, as seen in the first graph, this ratio is similar to that for other terrestrial planets at greater distances from the Sun but significantly higher than that for the Moon, which lost potassium during the giant impact that led to its formation. Relatively high abundances of other volatile elements, including sulfur right side of the animation , sodium, and chlorine, provide further evidence that Mercury is volatile-rich.
The high sulfur contents combined with low amounts of iron on the planet’s surface additionally indicate that Mercury formed from materials with less oxygen than those that formed the other terrestrial planets, providing an important constraint on theories for the formation of all of the planets in the inner Solar System. The internal magnetic field is times weaker than that of Earth and barely stands off the solar wind at the subsolar point to form the magnetosphere.
The interaction of the planetary field with the solar wind generates currents in the magnetosphere, which induce external magnetic fields with magnitudes similar to or larger than the planetary field in much of the magnetosphere. The floor of the kilometer-diameter crater Kertesz centered at The formation of hollows remains an active area of research, but the etched nature of the features, such as in this image, suggests that material is being lost from the surface to create the hollows.

Theological similarities[ edit ] Scholarly efforts to compare Hinduism and Judaism were popular during the Enlightenment era , in the process of arguing the deistic worldview.

Marian Feldman started with a presentation on the Open Educational Resource OER she created several years ago for her courses on ancient Mesopotamian art [see slides ]. She commented that Mesopotamian art may seem esoteric; not many people are readily familiar with the subject matter. The only text, The Art and Architecture of the Ancient Orient Frankfort was published in , and though new editions were released up until , the material was not updated.
The OER has other value as well. Feldman was also interested in highlighting these works of art in a time when many cultural heritage sites and objects in the region have been destroyed or are under threat. The OER as an open resource puts information in the public domain where it is easily accessible. The platform uses a Creative Commons license and content is freely accessible to all.
Feldman and her graduate students created 15 modules over two years.

Tifft and Greco presented as a team, reflecting their commitment to collaboration, and gave an impressive overview of the process they follow. Here are their slides for review. We should judge teaching not by the amount of knowledge it passes on, but by the enduring excitement it generates. One way to ensure that students leave your classroom with the knowledge you hope they will gain is to think about how to construct your course so that the desired learning outcomes align with your pedagogical approaches.
This is a teacher-centric approach as it revolves around the content that you as the instructor plan to disseminate. But what if you wanted to develop a course that was student-centric? Then you might take an approach known as backward design. With backward design you start the course planning process by formulating broad learning goals, then defining specific, measurable learning objectives. To clarify, learning goals express what you want students to get out of the course, while learning objectives detail the specific skills and level of understanding you want students to obtain.
Finally, you develop the course content and activities and choose supporting texts and readings. This process will help you to create a syllabus that informs the students what you expect them to be able to do at the end of the course, as you will share both the broad learning goals for the course and the learning objectives for each course section on the syllabus.

How do we know that everything in history books is based on fact? That is why history is always open to revision, and doing it requires a critical mind and the skills of a detective. I am a historian who loves mysteries, and this story is one of them. A Time of Scandal presents a new and expanded picture of a racy scandal about political corruption and bad behavior in the early s — a time when Prohibition had shut bars and spawned bootleggers, drugs were widely available at least in major cities, women could vote and wear short skirts but were still treated as second-class citizens, hostility toward immigrants was tinged with fear for the nation sound familiar?
