"Modeling" also includes a section overviewing the various simulation software packages available to modelers. Though developers like High-Performance Systems, Vensim, Pugh-Roberts, and PowerSim have made product enhancements to date, the sections from each company provide a great introduction to what is out there how each package can be applied.
The most valuable aspect of the book is probably in the case studies and methodological explorations of several authors. A number of key insights are offered as authors reflect upon the successes and shortcoming of the methods each chose to use to explore and develop models in a variety of business and public environments.
This is definitely a must have for any SD library.

I was a little disappointed, however, that the book focuses too much on Pentecostal denominations. In fact, all the ministers interviewed for this book were from churches like the AOG and COGIC. Very little attention is paid to Roman Catholicism, which itself has a very checkered history in regard to race relations in America, and the abolitionist activities of most mainstream Baptists are mentioned once before the once-aberrant views of the SBC on race relations become the focus of discussion as far as Baptists are concerned. (Except for the aberration of the SBC, the Baptists have an almost unparalleled history of excellent race relations, and credit should be given where credit is due. I personally think that the SBC should have disbanded and re-constituted itself as a new organization to erase the pro-slavery stain that the SBC inflicted on the Baptist name.) I was a little turned off by the excessive focus on churches like the AOG, COG, and COGIC, since I don't feel these groups are very representative of the mainstream of American evangelicalism and Christianity in general. But despite the somewhat unrepresentative sample of denominations, the suggestions in the book are easily applicable to any denominational church, and it's well worth reading.
Gor is also known as Counter-Earth because it is on the far side of the sun always blocked from view. Gor is slightly smaller than Earth, which works in Tarl Cabot's favor when he accedes to a cryptic message from the father he has not seen for decades and enters a space ship in the woods of New England, bringing with him a handful of earth. After all, Cabot is a college professor (like John Lange, the professor of philosophy who wrote these novels under the John Norman name), and has not been living the life of a warrior. But on Gor he is trained to be a Tarnsman, a rider of the great war birds. His mission is to capture the Home Stone of Ar, the great city-state that is the "Rome" of the Gorean world. The effort is an attempt to end the power of Marlenus, who had been given the power of "Ubar" (essentially the war chief) to handle an emergency, but who refused to give up power afterwards and is building an empire.
This 1966 novel is relative short, a little over 200 pages long, and ultimately it functions more aa a prologue to the rest of the series rather than an introduction. In the first half of the book the reader, like Tarl Cabot, is introduced to many key concepts that are developed in the future novels, from the practice of slavery and the joys of paga to caste-bound Gorean society and the technological restrictions imposed on the people of Gor by the mysterious Priest-Kings. When you go back and reread "Tarnsman of Gor," after you have gotten deeper into the series (i.e., "Slave Girl of Gor"), you will recognize the embryonic form of the Gorean philosophy as well: the concept of honor, the independence of men, the respect for the environment, the dangers of technology, and the great "truth" of female slavery." However, at first glance, the sword and sorcery elements are what hook the reader into this opening novel. The parallels between Marlenus of Ar and Julius Caesar of Rome are obvious, but Gor is a much more barbaric world than that of the Roman Empire and one of the fun aspects of reading these books is recognizing the bits and pieces of different warrior cultures Norman has brought to his creation.
"Tarnsman of Gor" ends in the same manner as "A Princess of Mars," which means the series effectively offers a second beginning in the next novel, "Outlaw of Gor," which is the first novel in what I think of as the Priest-Kings trilogy. I think that the fifth novel, "Assassins of Gor," is the high point of the series, after which it starts transforming itself into something significantly different. But those first five novels are certainly worth reading for those who like the Burroughs school of grand adventure and Norman improves greatly as a writer, creating memorable supporting characters and unique actions scenes.
The Priest-Kings have received a message from the Others to surrender Gor (with the fate of Earth in the balance as well). Tarl Cabot leaves Port Kar to travel to the great desert of the Tahari, where he encounters fierce warrior tribes, slavers, salt mines, and such. There he will encounter as well as woman warlord, whom he will bend to his will, and a bandit chief, whom he will befriend. The only problem is that Tarl Cabot has already been there and done that before, several times, with regards to both of those achievements. Furthermore, we have seen both done better. At its best "Tribesman of Gor" is an attempt to duplicate the success of Norman's most popular Gor novel (from a storytelling standpoint anyway) "Nomads of Gor." When I look back over the second ten books in the series it seems evident now that Norman was losing interest in the series, no doubt plagued by the fact that a new Gor novel had to come out every year when he switched publishers ("The New 1976 Gor Novel!").
"Outlaw of Gor" offers a radical reintroduction to the world of Gor. Tarl Cabot is returned to the Counter-Earth seven long years after he left, only to discover that his City-State of Ko-ro-ba has been ordered destroyed by the mysterious Priest-Kings. Just as no two stones of the city are allowed to stand together neither can two citizens of the city. An Initiate, one of those who serves the Priest-Kings, orders Cabot to submit to their will, but he refuses, and heads off across Gor for the Sardar Mountains, the legendary home of the Priest-Kings. Along the way he walks into Tharna, a town ruled by women. The head woman is called the Tatrix and the ruling class of women wear silver masks. The society is sterile and unproductive and although they try to break Cabot to their will, they are not going to have any more success than the Priest-Kings.
For me "Outlaw of Gor" is the weakest of the early Counter-Earth novels, mainly because Cabot's adventures in Tharna are a detour on his war to the Sardar Mountains. My best advice is to have the third novel, "The Priest-Kings of Gor" on hand so that as soon as you finish this one you can start the next book, especially since this is one of the rare times in the Gor series that the next novel pretty much picks up right where the previous one leaves off. For me these second and third novels are essentially one giant story.
However, from the perspective of the Gorean philosophy (i.e., way of life) developed by Norman (the pseudonym of philosophy professor John Lange), "Outlaw of Gor" is clearly the most important of the early novels. The novel was written in 1967, a time when the feminist movement was beginning to take shape, and it is easy to read "Outlaw of Gor" as something of a response to the times that were a-changin'. A city run by women is seen as being unnatural, and Norman begins to expand on some of the key elements of the Gorean philosophy: the concept of honor and the importance of the Home Stone, the dangers of technology versus respect for the environment, and the independence of men and the "truth" of female slavery. At this point in the series Norman is clearly courting controversy.
Of course, for many potential readers of this series, this is a make-or-break proposition. I preferred the adventure aspects of the Gor novels and abandoned the series in the early 1980s when I found myself flipping through the long discussions on "slavery" that were becoming omni-present in the books. I was also dismayed that other characters besides Tarl Cabot were becoming the focus of the book and the giant story arc regarding the Priest-Kings was becoming increasingly prolonged (and often ignored). But in terms of sword and sorcery novels, Norman's first half-dozen Gor novels create a unique barbaric world and his characterization of supporting characters improves with every outing If you start the series, at least make it through "Assassins of Gor," which I consider the apex of the series.
