"The Israelite Samaritan Today: Past, Present and Looking to the Future."

 

Today’s Israelite Samaritans are ‘living history’, as we respect and observe our way of life and heritage. Through our sometimes difficult past, we have learned to coexist harmoniously with our neighbours, and we are a bridge for peace (gesher leshalom) between all peoples . We are the root of the Abrahamic religions in the region, including Samaritanism, Judaism, Christianity, Islam, and the Druze and Bahai faiths. Though rooted deeply in the past, we are a vibrant modern community with contemporary enterprises and interests. In March 1919 there were only 141 individuals, in Nablus and Jaffa. By September 2014, the Israelite Samaritan Community numbered 770 souls, divided into four households, all in the Holy Land. This talk will explore the past, present, and future of the Israelite Samaritan people.

Benny recently published "The Israelite Samaritan Version of the Torah: First English Translation Compared with the Masoretic Version" with Eerdmans Publishing.

CHANGING LANES

Some form of the diagram below is often used as a pedagogical tool, and to represent a theoretical framework, in fluvial geomorphology, hydrology, and river science. It is called a Lane Diagram, and originated in a publication by E.W. Lane in 1955:

The diagram shows that stream degradation (net erosion and incision) and aggradation (net deposition) responds to changes in the relationship between sediment supply (amount of sediment, Qs, and typical sediment size, D50) and sediment transport capacity (a function of discharge or flow, Qw, and slope, S). The diagram is a very helpful metaphor in understanding the sediment supply vs. transport capacity relationship, and its effects on channel aggradation or degradation.

DYNAMIC EQUILIBRIUM (?) IN RIVERS

Nicholas Pinter, a Southern Illinois University geomorphologist, gave a nice talk yesterday on rivers and flooding in the 21st century as part of UK’s Water Week. Pinter’s talk got me to thinking about the concept of “equilibrium” in environmental systems and what it means to both geoscientists and laypersons. Pinter correctly noted that rivers tend toward dynamic equilibrium, and more specifically, dynamic metastable equilibrium. This means three things: First, the system (river) is more or less constantly changing (the dynamic part). Second, equilibrium is of the type envisioned in mathematics and systems theory—that is, a state or condition the system settles into after a change or perturbation, with no further connotation other than that the response to the change has run its course (I’ve called this “relaxation time equilibrium” in my work). Third, “metastable” means that these equilibrium states are not necessarily stable and self-maintaining, and may be sensitive to future disturbances—even relatively small ones. Pinter’s message is that dynamic equilibrium in rivers means that rivers are constantly changing.
