The Art of Teaching Art
Authors: Rockman Deborah A.
Published: November 2020

Often the finest artists do not make the best teachers. Many frustrated college students of art know this all too well as they suffer through unstructured classes with inexperienced teachers or graduate student instructors. In these situations, it is easy to blame the teachers. But the problem is largely institutional: most students graduating with MFAs from art schools receive little if any instruction in teaching art. If you find yourself in this predicament as teacher or student, this book is for you. The first book to provide a comprehensive guide for teaching college-level art, The Art of Teaching Art is the culmination of respected artist and instructor Deborah Rockman's two decades of teaching experience. Believing that drawing is the backbone of all of the visual arts, she begins with a complete explanation of drawing concepts that apply to any subject matter, e.g., composition, sighting processes, scaling techniques, and methods for linear and tonal development. She then illustrates these concepts with step-by-step methods that easily translate to classroom exercises. Next, she applies the drawing principles to every artist's most important and challenging subject, the human figure. After an extended section on understanding and teaching perspective that explores illusionistic form and space, the focus of the book shifts to the studio classroom itself and the essential elements that go into making an effective learning environment and curriculum. From preparing materials lists and syllabi, to setting up still-lifes, handling difficult classroom situations, critiquing and grading student artworks, and shooting slides of student artworks, she leaves no stone unturned.
Essential Skills and Information: What Every Teacher and Every Student Should Know about Drawing
Authors: Rockman Deborah A.
Published: November 2020

Students often go through the motions of sighting without really understanding what they are doing and why it works. A little understanding of the principles of sighting goes a long way toward encouraging students to use the process to their advantage. . . . Why Use Sighting? . . . Many students have found that they are shining stars when it comes to copying photographs or working from other existing two-dimensional sources. They are often confounded when they discover that drawing from observation of three-dimensional forms does not yield the same strong results, the same degree of accuracy they are accustomed to. It is helpful for both the instructor and the student to understand why this occurs. Drawing or representing a three-dimensional form on a two-dimensional surface requires, in essence, a language translation. The language of two dimensions is different from the language of three dimensions. We must observe the three-dimensional form and translate it into a language that will be effective on a two-dimensional surface, such as a piece of drawing paper. When students draw from an existing two-dimensional source, the translation from 3-D to 2-D has already been made for them. But when they are referring to the actual form, they must make the translation themselves. The process of sighting provides the method for making this translation easily and effectively. A sighting stick is the basic tool for the process of sighting. I recommend using a IO" to I2" length of 1⁄8" dowel. Suitable alternatives include a slender knitting needle, a shish-kebab skewer, or a length of metal cut from a wire clothes hanger. Your sighting stick should be straight. I discourage the use of a drawing pencil as a sighting stick simply because the thickness of the pencil often obscures information when sighting. The more slender the tool, the less it interferes with observing the form or forms being drawn. However, in the absence of a more suitable tool, a pencil will suffice. In presenting sighting principles to a class, it is vital to go beyond a verbal explanation. For students to effectively understand the process, it is strongly recommended that teacher and students walk through the process together, exploring the various ways of applying sighting.
Self-Organization and Templates: Application to Data Analysis and Graph Partitioning
Authors: Bonabeau Eric , Dorigo Marco , Theraulaz Guy
Published: November 2020

The biological phenomena described in the previous chapter were corpse aggregation and brood sorting by ants. The clusters of items obtained with the models introduced in sections 4.3.1 and 4.3.2 emerged at arbitrary locations. The underlying self-organizing process, whereby large clusters grow even larger because they are more attractive than smaller clusters, does not ensure the formation of clusters at specific locations. In the two biological examples described in this chapter, the self-organizing dynamics of aggregation is constrained by templates. A template is a pattern that is used to construct another pattern. The body of a termite queen or a brood pile in ants are two examples of structures—the second one resulting from the activities of the colony—that serve as templates to build walls. Walls built around the termite queen form the royal chamber; walls built around the brood pile form the ant nest. When a mechanism combines self-organization and templates, it exhibits the characteristic properties of self-organization, such as snowball effect or multistability, and at the same time produces a perfectly predictable pattern that follows the template. The two nonparametric algorithms presented in chapter 4, one for multidimensional scaling and the other for graph partitioning, can be made parametric through the use of templates. The number of clusters of data points or vertices can be predefined by forcing items to be deposited in a prespecified number of regions in the space of representation, so that the number of clusters and their locations are known in advance. In the previous chapter, we saw how the attractivity of corpses or the differential attractivity of items of different types could lead to the formation of clusters of specific items. Self-organization lies in this attractivity, which induces a snowball effect: the larger a cluster, the more likely it is to attract even more items. But selforganization can also be combined with a template mechanism in the process of clustering. A template is a kind of prepattern in the environment, used by insects— or by other animals—to organize their activities.
Terrain-Forced Flows
Authors: Whiteman C. David
Published: November 2020

Winds associated with mountainous terrain are generally of two types. Terrain-forced flows are produced when large-scale winds are modified or channeled by the underlying complex terrain. Diurnal mountain winds are produced by temperature contrasts that form within the mountains or between the mountains and the surrounding plains and are therefore also called thermally driven circulations. Terrain-forced flows and diurnal mountain winds are nearly always combined to some extent. Both can occur in conjunction with small-scale winds, such as thunderstorm inflows and outflows, or with large-scale winds that are not influenced by the underlying mountainous terrain. Terrain forcing can cause an air flow approaching a mountain barrier to be carried over or around the barrier, to be forced through gaps in the barrier, or to be blocked by the barrier. Three factors determine the behavior of an approaching flow in response to a mountain barrier: •the stability of the air approaching the mountains, •the speed of the air flow approaching the mountains, and •the topographic characteristics of the underlying terrain. Unstable or neutrally stable air (section 4.3) is easily carried over a mountain barrier. The behavior of stable air approaching a mountain barrier depends on the degree of stability, the speed of the approaching flow, and the terrain characteristics. The more stable the air, the more resistant it is to lifting and the greater the likelihood that it will flow around, be forced through gaps in the barrier, or be blocked by the barrier. A layer of stable air can split, with air above the dividing streamline height flowing over the mountain barrier and air below the dividing streamline height splitting upwind of the mountains, flowing around the barrier (figure 10.1), and reconverging on the leeward side (section 10.3.2). A very stable approaching flow may be blocked on the windward side of the barrier (section 10.5.1). Moderate to strong cross-barrier winds are necessary to produce terrain-forced flows, which therefore occur most frequently in areas of cyclogenesis (section 5.1) or where low pressure systems (figure 1.3) or jet streams (section 5.2.1.3) are commonly found. Whereas unstable and neutral flows are easily lifted over a mountain barrier, even by moderate winds, strong cross-barrier winds are needed to carry stable air over a mountain barrier.
Evolutionary Modeling of Routes: The Case of Road Design
Authors: Pereira Ângela Guimarães
Published: November 2020

In this study a route is defined as the path that a linear structure or facility follows in the terrain. Linear structures comprise facilities such as roads, motorways, railways, pipelines, electrical power lines, and telephone cables, each of these structures requiring specific technical parameters in what concerns the geometry of the path and having different effects on the terrain they traverse. Amongst these structures, roads and motorways are the group that creates the greatest overall impact; accordingly Portuguese legislation requires an environmental impact assessment (EIA) process as part of the necessary licensing approval. Usually the alternative (or alternatives) that undergo the EIA process is justified in terms of technical and economical issues. The result is that if major environmental impacts are identified by the EIA study, a myriad of mitigation measures are proposed, very seldom the redesign of the path being carried out (Guimarães Pereira & Antunes, 1996). Preliminary studies that precede the implementation of these types of projects are technically detailed and often come together with economical feasibility studies, shelving environmental issues for later assessment. In the methodology proposed in this chapter a multidimensional evaluation methodology, multicriteria evaluation, will be combined with the robustness of a search methodology, genetic algorithms (GAs) to generate alternative road routes that take into consideration environmental, economical, technical, and social criteria. These criteria are referenced to the physical space where the road is to be placed and therefore this methodology is embedded into a geographic information system (GIS). Genetic algorithms are particularly attractive to apply to multi-modal problems, allowing the exploration of spatial features to eventually find “best compromise” alternatives because these algorithms proceed their search by maintaining a population of solutions, that they can simultaneously exploit for their efficiency.1 Moreover, the particular mixing mechanism provides the means to recombine solutions and explore the search space. The remainder of this chapter describes evolutionary modeling of road routes, in particular the coding onto a GA of the geometric algorithm that accounts for the technical aspects of motorway siting. The details of the implementation of the MCDA-GA methodology, running within the GIS GRASS 4.1 (Geographic Resources Analysis Support System) and its application to generate and evaluate alternative routes of a section of a Portuguese complementary itinerary (IC7) will be presented.
Soil Development and Distribution in the Shortgrass Steppe Ecosystem
Authors: Kelly Eugene F. , Yonker Caroline M.
Published: November 2020

Beneath the gently rolling, seemingly mundane topography that characterizes the shortgrass steppe is a complex mosaic of soils. Many of these soils are superimposed upon older, buried soils that formed in other millennia under different climatic regimes. The nature of this soil mosaic reveals much about the past and dictates much about the future of the shortgrass steppe. There is considerable heterogeneity among soils of the shortgrass steppe, yet they maintain a high degree of homogeneity when contrasted with soils of other ecosystems. The driving forces that make these soils alike are a semiarid climate and a resilient plant community ( P ielke and Doesken, chapter 2, this volume; and Lauenroth, chapter 5, this volume). The combined effects of vegetation and climate on soil development yield generally predictable results. Shortgrass steppe soils are characterized by the accumulation of organic matter in the surface (0–20 cm). Approximately 60% of the graminoid root mass resides in the - rst 10 cm of mineral soil (Schimel et al., 1986); 90% is contained in the surface 20 cm (Schimel et al., 1985). Surface horizons typically are darker hued than underlying horizons and have organic carbon contents that average 1% to 3% (Yonker et al., 1988). Shortgrass steppe soils maintain a high-percent base saturation (and high pH) because of low leaching and weathering potentials that result from semiarid conditions. Zones of secondary calcium carbonate accumulation are common in subsurface horizons and may appear as threads, seams, or nodules (Blecker et al., 1997). In addition, these soils are characterized by zones of secondary clay accumulation in subsurface horizons; clay accumulations are a result of either the in situ weathering of primary minerals or the translocation of clay minerals leached from the surface horizon. In either case, the maximum depth of accumulation gives some indication of the time-averaged depth of the wetting front in the soil pro- le (Blecker et al., 1997). The factors that produce considerable heterogeneity among the soils of the shortgrass steppe are related to parent material, the age of the soil, and the subtleties of topography. These factors vary at a - ner scale than either vegetation or climate.
Ecology of Mammals of the Shortgrass Steppe
Authors: Stapp Paul , Van Horne Beatrice
Published: November 2020

At first glance, the shortgrass steppe seems to offer little in the way of habitat for mammals. The expansive rolling plains, with little topographic relief or vegetative cover, provide minimal protection from predators or the harsh weather typical of the region. The short stature of the dominant native grasses prevents the development of any significant litter layer, and although snowfall can often be significant, too little accumulates to form the subnivean habitats that support small mammal populations in forests and more productive grasslands in winter. As a consequence, ecologists have typically considered the vertebrate fauna of the shortgrass steppe to be depauperate compared with other Great Plains grasslands, a hardy collection of generalists living in sparse populations. Although this characterization may generally be accurate, it has led mammalian ecologists to overlook the fauna of the shortgrass steppe in favor of that of other grasslands. It is precisely these circumstances, however, that suggest that a long-term approach may be necessary to understand the dynamics of mammal populations here. Relatively few such studies have been completed to date, but we can use the comparative and experimental results that are available to begin to determine what factors might be important. Here we review research on mammals in the shortgrass steppe, with the goal of identifying the general patterns and processes that contribute to them. Our review is roughly divided into four parts. We begin by describing the mammal communities and their broad habitat associations in shortgrass steppe environments. We then review the history of mammal research in the region to synthesize what these studies (many unpublished) have taught us about the most important determinants of the distribution and abundance of native species. Studies of mammal\ populations in the northern shortgrass steppe have spanned nearly 40 years, and we next describe some major patterns that have emerged from studies during this period. Much of this past research focused on the role of mammals in the structure and function of shortgrass steppe ecosystems, and we revisit this issue in some detail, with special emphasis on the important and sometimes controversial role of prairie dogs and other burrowing rodents. Finally, we end by considering how humans, and especially agriculture and its related activities, affect the diversity, abundance, and persistence of resident mammal populations.
Cattle Grazing on the Shortgrass Steppe
Authors: Hart Richard H. , Derner Justin D.
Published: November 2020

Cattle are the primary grazers on the shortgrass steppe. For example, during the late 1990s, 21 shortgrass counties in Colorado reported about 2.36 million cattle compared with 283,000 sheep (National Agricultural Statistics Service, USDA, 1997a), 60,000 pronghorn antelope, and a few thousand bison (Hart, 1994). Assuming one bison or five to six sheep or pronghorn consume as much forage as one bovine (Heady and Child, 1994), cattle provide about 97% of the large-herbivore grazing pressure in this region. The ratio of cattle to other grazers is even greater in the remainder of the shortgrass steppe. In 1997, the three panhandle counties of Oklahoma reported 387,000 cattle and only 1300 sheep, whereas the 38 panhandle counties of Texas reported 4.24 million cattle and 14,000 sheep (National Agricultural Statistics Service, USDA, 1997b,c). How ever, only a bout half the cattle in the panhandle counties of Texas and Oklahoma graze on rangeland the remainer are in feedlots. Rangeland research on the shortgrass steppe (Table 17.1 describes the parameters of the major research stations in the shortgrass steppe) has included a long history of both basic ecology and grazing management. The responses of rangeland plant communities to herbivory are addressed by Milchunas et al. (chapter 16, this volume) and to disturbance are discussed by Peters et al. (chapter 6, this volume). Here we focus on research pertaining to three management practices important to cattle ranching on shortgrass steppe: stocking rates, grazing systems, and extending the grazing season via complementary pastures and use of pastures dominated by Atriplex canescens [Pursh] Nutt (fourwing saltbush). Stocking rate, de. ned as the number of animals per unit area for a speci. ed time period, is the primary and most easily controlled variable in the management of cattle grazing. Cattle weight gain responses to stocking rate or grazing pressure (animal days per unit of forage produced) have been quanti. ed in several grazing studies on the shortgrass steppe (Bement, 1969, 1974; Hart and Ashby, 1998; Klipple and Costello, 1960). Average daily gains per animal are better estimated as a function of grazing pressure, rather than stocking rate, as forage production is highly variable in this semiarid environment (Lauenroth and Sala, 1992; Milchunas et al., 1994).
Still Life Theory
Authors: Cook Matthew
Published: November 2020

In Conway’s Game of Life [2], if one starts with a large array of randomly set cells, then after around twenty thousand generations one will see that all motion has died down, and only stationary objects of low period remain, providing a final density of about .0287. No methods are known for proving rigorously that this behavior should occur, but it is reliably observed in simulations. This brings up several interesting related questions. Why does this “freezing” occur? After everything has frozen, what is the remaining debris composed of? Is there some construction that can “eat through” the debris? If we start with an infinitely large random grid, so that all constructions appear somewhere, what will the long term behavior be? It seems clear that knowing the composition of typical debris is central to many such questions. Much effort has gone into analyzing the objects that occur in such stationary debris, as well as into determining what stationary objects can exist at all in Life [4, 8], Both of these endeavors depend on having some notion of what an “object” is in the first place. One simple notion is that of an island, a maximal set of live cells connected to each other by paths of purely live cells. But many common objects, such as the “aircraft carrier,” are not connected so strongly. They are composed of more than one island, but we think of them as a single object anyway, since their constituent islands are not separately stable. Any pattern that is stable (has period one, i.e., does not change over time) is called a still life. Since a collection of stable objects can satisfy this definition, the term strict still life is used to refer to a single indivisible stable object, and pseudo still life is used to refer to a stable pattern that is composed of distinct strict still lifes. For example, the bi-block is a pseudo still life, since it is composed of two blocks, but the aircraft carrier is a strict still life, since its islands are not stable on their own.
Phase Transition via Cellular Automata
Authors: Moran Gadi
Published: November 2020

The dynamics of unit-charged graphs under iterated local majority rule observed in Moran [2] strongly suggested to me a phase-transition phenomenon. In a correspondence with D. Ruelle on this matter in late 1993, he expressed his feelings that the connection was too vague and that temperature was absent in it. This note is a reproduction of my 1993 response, where I try to force my suggestive feelings into a bit more formal frame. A recent work of Yuval Ginosar and Ron Holzman [1], which extends Moran [2], allows us to replace the definition of a solid, given in section 4, by a sharper one, namely that of a “puppet” in their terminology. This means that in section 4 we may define a G ∈ Y to be a solid if every initial charge upon it decays under these dynamics—possibly in infinite time—into a time-periodic charging of a time period not longer than two. This note suggests an approach to the phenomenon of phase transition based on the behaviour of some cellular automata on infinitely countable nets, as noted recently in Moran [2]. Specifically, we use a majority automaton operating simultaneously on a countably infinite graph as a test device determining its “phase.” Results in Moran [2] suggest some sharp partition of a configuration space made up of the totality of such graphs into “solids,” where the only periods allowed for the automaton are 1 or 2, versus the others. Results in Moran [2] allow also the introduction of a “temperature” functional—a numerical parameter defined for each configuration, with the property that a configuration is “solid” whenever its “temperature” is negative. We first describe a possible physical interpretation of such a model, taking the nodes of a graph to be “particles” (stars, electrons, ions, atoms, molecules, radicals—as the case may be) in some Riemannian manifold. Our interpretation is obviously open to a wide diversity of modifications. It is hoped that in spite of its admittedly speculative nature, it may invoke a novel approach to the theoretical treatment of phase transition.
Applied Stochastic Hydrogeology

Published: November 2020

Stochastic Subsurface Hydrogeology is the study of subsurface, geological heterogeneity, and its effects on flow and transport process, using probabilistic and geostatistical concepts. This book presents a rational, systematic approach for analyzing and modeling subsurface heterogeneity, and for modeling flow and transport in the subsurface, and for prediction and decision-making under uncertainty. The book covers the fundamentals and practical aspects of geostatistics and stochastic hydrogeology, coupling theoretical and practical aspects, with examples, case studies and guidelines for applications, and provides a summary and review of the major developments in these areas.
Beroea
Authors: Fant Clyde E. , Reddish Mitchell G.
Published: November 2020

Virtually nothing remains from the ancient city of Beroea, once the second city of the Macedonian Empire. In the 1st century the Apostle Paul found Beroea hospitable to his message, and today the city contains the most notable individual monument in Greece to the Christian missionary. The ancient city of Beroea today is known as Veria, located 42 miles west of Thessaloniki and 9 miles northwest of Vergina. Public buses are available from Thessaloniki’s KTEL stations (be sure to use the west side stations). Check carefully for departing and returning times, as the frequency of connections varies. Fares are inexpensive, less than $10 round trip. It is possible, if desired or time is limited, to make a day trip from Thessaloniki to nearby Vergina, go on to Veria, and return. Beroea was first mentioned by Thucydides in his histories when he records that the Athenians failed to take the city by siege in 432 B.C.E., during the Peloponnesian War. Plutarch later tells of a successful siege of Beroea in 288 B.C.E., after which the city was occupied by Pyrrhus. The Gauls who later robbed the royal tombs at Vergina were unsuccessful in taking Beroea. The city became part of the Roman Empire in 148 B.C.E. and was the site of training for the armies of Pompey, who spent the winter of 49–48 B.C.E. in Beroea prior to the battle of Pharsalos (48 B.C.E.). In the 1st century C.E. Beroea found favor with several of the Roman emperors and became an international city of varied races and religions. The Apostle Paul visited the city in 50 C.E. Later Diocletian made Beroea one of the two capitals of Macedonia. The biblical account of Paul’s visit to Beroea, following his escape from the hostility at Thessalonica, is found in Acts 17:10–15: . . . That very night the believers sent Paul and Silas off to Beroea; and when they arrived, they went to the Jewish synagogue. These Jews were more receptive than those at Thessalonica, for they welcomed the message very eagerly and examined the scriptures every day to see whether these things were so. . . .
Philippi
Authors: Fant Clyde E. , Reddish Mitchell G.
Published: November 2020

An important city in the Roman and early Christian period, Philippi exists today only as an archaeological site. The impressive remains of this once flourishing city on the Via Egnatia, the important Roman highway in the area, are frequently visited by modern pilgrims retracing the steps of the Apostle Paul, who started a Christian church in the city. The ruins of ancient Philippi are easy to find. The archaeological site is located in the region of Macedonia, alongside highway 12 between Kavala and Drama, next to the village of Krenides. Settlement in the area occurred as early as the Middle Neolithic period (ca. 5000 B.C.E.). In 360 B.C.E., Greek colonists from the island of Thasos, led by the exiled Athenian politician Kallistratos, founded the colony of Krenides on the site of what later became Philippi. The colony at Krenides (which means “spring,” because of the abundant streams in the area) provided the Thasians with access to the rich resources of the area, particularly its silver and gold mines. Threatened by the Thracian tribes in the area, the colonists at Krenides asked Philip II of Macedonia for military assistance in 356 B.C.E. Eager to gain control of the area, and particularly its rich resources, Philip conquered the city and renamed it Philippi in his honor. Philip fortified the city with new walls, increased the city’s population with Macedonian mercenaries, and extracted large amounts of gold and silver from the mines in the area. Although little is known of the city during the Hellenistic period, this was apparently a prosperous time for Philippi. In the 2nd century B.C.E., the Romans occupied Macedonia and turned the area into a Roman province. During the Roman period, the most i important event associated with Philippi took place. In 42 B.C.E. the forces of Octavian (later known as Augustus) and Mark Antony defeated the armies of Brutus and Cassius (the murderers of Julius Caesar) on the plains just outside the west wall of Philippi. This battle brought to an end the Roman Republic.
Colossae
Authors: Fant Clyde E. , Reddish Mitchell G.
Published: November 2020

At one time a thriving city in the fertile valley of the Lycus River, the city of Colossae is almost forgotten today. If not for its significance to the Bible, the site of ancient Colossae, now only an unexcavated mound, would be visited very seldom. Colossae was situated near the Lycus River (today the Aksu Çay), the chief tributary of the Meander River. Located in the Phrygian region of Asia Minor, the city was approximately 120 miles east of Ephesus. During the 5th and 4th centuries B.C.E. Colossae was a large and prosperous city. At that time the leading city of the Lycus Valley, Colossae was eventually eclipsed in importance during the Hellenistic and Roman periods by the neighboring cities of Laodicea and Hierapolis. The textile industry flourished in the Lycus Valley, particularly because of goods made from the exceptionally fine wool produced in the area. Colossae was well known for its purple-colored wool. The economic prosperity of the city was also due to its being located on the main trade route from the Aegean coast to the Euphrates. Like Laodicea and Hierapolis, Colossae likely was damaged by the severe earthquake that struck the Lycus Valley in 60 C.E. By the 9th century the site was abandoned, its remaining inhabitants having moved to the nearby town of Chonae (modern Honaz). To reach the ruins of ancient Colossae, take highway 320 east from Denizli toward Dinar. Approximately 12 miles from Denizli, turn right onto the road for Honaz. After traveling approximately 4 miles, turn left. The site of ancient Colossae, a low hill in a field, is about 6 miles on the right. The ancient city of Colossae is remembered today primarily because one of the letters in the New Testament is addressed to “the saints and faithful brothers and sisters in Christ in Colossae” (Col 1:2). Aside from this one reference, the city of Colossae does not appear in the New Testament. The Letter to the Colossians claims to be a letter from the Apostle Paul, although its authorship is sometimes attributed to an anonymous disciple of Paul’s who wrote in the name of Paul.
Lystra
Authors: Fant Clyde E. , Reddish Mitchell G.
Published: November 2020

Few visitors seek out the ancient site of Lystra. Neither its unexciting location in the Anatolian plain nor its unexcavated mound offer much enticement except to the hard-core adventurer seeking to trace the route of the Apostle Paul. The ancient city of Lystra was located near the modern village of Hatunsaray, approximately 24 miles southwest of Konya in south-central Turkey. In 1885, about a mile north of Hatunsaray, on a mound called Zoldera (or, variously, Zordula), J. R. Sitlington Sterrett discovered a stone block approximately 3.5 feet tall and 1 foot thick. On the stone was the Latin inscription “DIVVM AVG COL IVL FELIX GEMINA LVSTRA CONSECRAVIT D D,” which uses the Latinized version “Lustra” for the name of the city. The discovery of this monument, erected to honor Caesar Augustus, who founded the Roman colony of Lystra, made identification of the site of ancient Lystra possible. Lystra was a part of the Lycaonian region of Asia Minor, an area bordering Phrygia on the west, Cappadocia on the east, and the ethnic Galatian region on the north. To the south were the Taurus Mountains. Earlier made a part of the province of Cilicia, Lycaonia was put under the control of Amyntas, an ally and client king of the Romans, in 36 B.C.E. When Amyntas died in 25 B.C.E., Lycaonia became a part of the Roman province of Galatia. Because the site of Lystra has yet to be excavated, little can be said with certainty about the earliest settlements on the site. The evidence of Hellenistic-style pottery and Greek inscriptions from the Roman period would suggest that at least a small village existed here during the Hellenistic period. Of the coins that have been found that originated from Lystra, none predates the time of the Roman colony, perhaps indicating that any pre-Roman settlement was not significant enough to issue coins. Emperor Augustus established Lystra as a Roman colony, likely in 25 B.C.E. at the same time that several other Roman colonies, including Pisidian Antioch, were founded. While all the colonies were established to help secure Roman control over Asia Minor, Lystra was likely founded specifically to suppress the Homanadenses and other mountain tribes in south-central Asia Minor who were hindering Roman control of the area.
Sardis

Published: November 2020

A city with a strong and vibrant Jewish community during the Roman period, as well as a center for the worship of Artemis and home to a significant Christian community, Sardis is an intriguing place to visit for anyone interested in biblical studies or ancient religious history. The partially restored 3rd-century-C.E. synagogue in the city is the largest known synagogue outside Palestine from ancient times. Ancient shops, a bath-gymnasium complex, and the Temple of Artemis provide glimpses of the life of this ancient city. Once the capital of the ancient Lydian Kingdom, Sardis (Sart) lies approximately 60 miles east of Izmir along the modern highway (E96/300) connecting Izmir to Ankara in the Hermus River valley (today called the Gediz River). Portions of the ruins of Sardis are situated adjacent to the highway and are easily accessible. The ancient city was built along the Pactolus River, a tributary of the Hermus, and at the foothills of the Tmolus Mountains. The city’s acropolis was strategically located atop a spur of the Tmolus Mountains. The Tmolus Mountains (or Mt. Tmolus) were, according to some ancient traditions, the birthplace of the gods Dionysus and Zeus. Sardis first came to prominence during the 1st millennium B.C.E. when it served as the center of the powerful Lydian kingdom, which encompassed most of the western half of Asia Minor. The Lydians supposedly were the first to develop a technique to dye wool and also to invent dice games, knucklebones, and other games. (Interestingly, archaeologists found a terra-cotta die in the ruins at Sardis.) Legend says that Midas, the mythical Phrygian king, was able to rid himself of his golden touch by bathing in the Pactolus River. As a result, the sands of the river turned to gold. Though legendary, this account points nonetheless to the enormous wealth enjoyed by the Lydian kingdom. The earliest Lydian rulers belonged to the Heraclid dynasty, which according to Herodotus (5th-century-B.C.E. Greek historian) lasted 505 years. They were succeeded by the Mermnad dynasty, of which the first king was Gyges (r. ca. 680–ca. 652 B.C.E.).
Atomic Bombs, Nuclear Fallout, and Dental X-Rays
Authors: Goldstein Inge F. , Goldstein Martin
Published: November 2020

One of the first pictures made with X-rays by Wilhelm Roentgen, when he discovered them in 1895, was of the hand of a colleague of his, a Dr. von Koelliker. The bones of his hand and a ring he was wearing stand out clearly; the flesh appears as a faint halo around the bones. A glance at the photograph makes it obvious why the medical possibilities of X-rays were almost immediately recognized. X-rays were used first for diagnosis, and later for treatment of disease as well, but they were the first form of radiation shown also to cause disease. In the early years of radiology, radiologists used to hold the X-ray film in place close to the patient’s body, thus receiving intense exposures of their hands. There were unexpected difficulties in arranging for a celebratory dinner for the Society of Radiologists in Philadelphia on the twenty-fifth anniversary of the discovery of X-rays: so many of the members had lost fingers or hands that they found it too awkward to eat in public. The discovery of X-rays led in 1896 to the discovery of radioactivity by Henri Becquerel, who observed, almost by accident, that compounds of the metallic element uranium emitted a kind of radiation that like X-rays passed through the black paper photographic film was wrapped in and darkened the film. Marie and Pierre Curie, following up his work, found that the strongest sources of the radioactivity were impurities in the uranium compounds and were able to extract small quantities of other much more radioactive elements from them, including polonium and radium. Becquerel and the Curies were awarded the Nobel Prize in physics in 1903. At first, the energy given out steadily by radioactive substances could not be explained, and some scientists proposed that they might provide unlimited sources of energy. It was soon shown that radioactive substances, like any other fuel, are used up as energy is given out: the radioactive atoms are undergoing disintegration into other, different kinds of atoms. When an atom of uranium-238 emits alpha radiation, it changes at the same time into an atom of a rare element called thorium, also radioactive.
Spin Separation and the Modified Dirac Equation
Authors: Dyall Kenneth G. , Faegri Knut

In the preceding chapters, the theory for calculations based on the Dirac equation has been laid out in some detail. The discussion of the methods included a comparison with equivalent nonrelativistic methods, from which it is apparent that four-component calculations will be considerably more expensive than the corresponding nonrelativistic calculations—perhaps two orders of magnitude more expensive. For this reason, there have been many methods developed that make approximations to the Dirac equation, and it is to these that we turn in this part of the book. There are two elements of the Dirac equation that contribute to the large amount of work: the presence of the small component of the wave function and the spin dependence of the Hamiltonian. The small component is primarily responsible for the large number of two-electron integrals which, as will be seen later, contain all the lowest-order relativistic corrections to the electron–electron interaction. The spin dependence is incorporated through the kinetic energy operator and the correction to the electronic Coulomb interaction, and also through the coupling of the spin and orbital angular momenta in the atomic 2-spinors, which form a natural basis set for the solution of the Dirac equation. Spin separation has obvious advantages from a computational perspective. As we will show for several spin-free approaches below, a spin-free Hamiltonian is generally real, and therefore real spin–orbitals may be employed for the large and small components. The spin can then be factorized out and spin-restricted Hartree–Fock methods used to generate the one-electron functions. In the post-SCF stage, where the no-pair approximation is invoked, the transformation of the integrals from the atomic to the molecular basis produces a set of real molecular integrals that are indistinguishable from a set of nonrelativistic MO integrals, and therefore all the nonrelativistic correlation methods may be employed without modification to obtain relativistic spin-free correlated wave functions. In most cases, spin–free relativistic effects dominate the relativistic corrections to electronic structure. We will show later that in a perturbation expansion based on the nonrelativistic wave function, the spin-free effects for a closed-shell system enter in first order, whereas the spin-dependent effects make their first contribution in second order.
Population Cycles of Small Rodents in Fennoscandia
Authors: Hanski Ilkka , Henttonen Heikki

The earliest records of small rodents in Fennoscandia date back to the sixteenth century. Ziegler (1532) and Magnus (1555) reported mass occurrences of the Norwegian lemming (Lemmus lemmus), which supposedly descended from the sky, a hypothesis that prevailed for the next 300 years (Henttonen and Kaikusalo 1993)! The first scientific papers on lemmings (Fellman 1848, Ehrstöm 1852) clearly recognized periodicity of lemming dynamics in Finnish Lapland (for a review see Henttonen and Kaikusalo 1993). Collett (1878, 1895, 1911-12) compiled extensive data on lemmings in Norway more than 100 years ago, providing critical material for Elton (1924) to describe the population cycle of small rodents. As these early records suggest, the Norwegian lemming is the most conspicuous member of the small rodent community in northern Fennoscandia, both in appearance and abundance, but apart from mountainous regions, the Fennoscandian small rodent cycle actually refers to Microtus and Clethrionomys voles rather than to lemmings. At present, the small rodent cycle in Fennoscandia is one of the best documented examples of cyclic population dynamics. Several recent papers review the state of knowledge on small rodent population dynamics in Fennoscandia and elsewhere (Norrdahl 1995, Krebs 1996, Boonstra et al. 1998, Stenseth 1999, Henttonen and Hanski 2000, Turchin and Hanski 2001). One might think that the “puzzle” of rodent cycles has been solved a long time ago, and that the Fennoscandian small rodent dynamics might serve as a useful reference for the study of cyclic populations in general. Unfortunately, this is not so, although substantial progress has been made over the past 15 years, so that we now have a well-supported hypothesis to explain the small rodent dynamics in Fennoscandia. There are several reasons why progress has been slow in unraveling the secrets of the small rodent cycle. First, small rodents occur in great abundance throughout the world and there was a tendency to assume that the rodent cycle, especially in northern latitudes, was a universal phenomenon, calling for a universal explanation (Krebs and Myers-1974). However, this is not so.
Soils for Fine Wines
Authors: White Robert E.
Published: November 2020

In recent years, viticulture has seen phenomenal growth, particularly in such countries as Australia, New Zealand, the United States, Chile, and South Africa. The surge in production of quality wines in these countries has been built largely on the practice of good enology and investment in high technology in the winery, enabling vintners to produce consistently good, even fine wines. Yet less attention has been paid to the influence of vineyard conditions on wines and their distinctiveness-an influence that is embodied in the French concept of terroir. An essential component of terroir is soil and the interaction between it, local climate, vineyard practices, and grape variety on the quality of grapes and distinctiveness of their flavor. This book considers that component, providing basic information on soil properties and behavior in the context of site selection for new vineyards and on the demands placed on soils for grape growth and production of wines. Soils for Fine Wines will be of interest to professors and upper-level students in enology, viticulture, soils and agronomy as well as wine enthusiasts and professionals in the wine industry.
Animal Anatomy for Artists

From the author of the classic Human Anatomy for Artists comes this user-friendly reference guide featuring over five hundred original drawings and over seventy photographs. Designed for painters, sculptors, and illustrators who use animal imagery in their work, Animal Anatomy for Artists offers thorough, in-depth information about the most commonly depicted animals, presented in a logical and easily understood format for artists--whether beginner or accomplished professional. The book focuses on the forms created by muscles and bones, giving artists a crucial three-dimensional understanding of the final, complex outer surface of the animal. Goldfinger not only covers the anatomy of the more common animals, such as the horse, dog, cat, cow, pig, squirrel, and rabbit, but also the anatomy of numerous wild species, including the lion, giraffe, deer, hippopotamus, rhinoceros, elephant, gorilla, sea lion, and bear. Included are drawings of skeletons and how they move at the joints, individual muscles showing their attachments on the skeleton, muscles of the entire animal, cross sections, photographs of live animals, and silhouettes of related animals comparing their shapes and proportions. He offers a new and innovative section on the basic body plan of four-legged animals, giving the reader a crucial conceptual understanding of overall animal structure to which the details of individual animals can then be applied. The chapter on birds covers the skeleton, muscles and feather patterns. The appendix presents photographs of skulls with magnificent horns and antlers and a section on major surface veins. Incredibly thorough, packed with essential information, Animal Anatomy for Artists is a definitive reference work, an essential book for everyone who depicts animals in their art.
