    Population, Growth, Suburbs, MetropolitanI will review the major changes in the distribution of the metropolitan population of the United States (US), as revealed by the 2010 data recently released by the US Census. These data allow us to track recent changes and provide the basis for a discussion of longer-term trends identified in previous studies of US cities (Short 2006, 2007) and the city suburban nexus (Hanlon et al. 2010). In brief summary, the paper will show the continuing metropolitanization and suburbanization of the US population. A more nuanced picture will reveal evidence of stress in suburban areas and population resurgence in selected central city areas. Overall, the story is one of a profound revalorization and a major respatialization of the US metropolis.Hindawi Publishing Corporation International Journal of Population Research Volume 2012, Article ID 207532, 6 pages doi:10.1155/2012/207532 Review Article Metropolitan USA: Evidence from the 2010 Census John Rennie Short Department of Public Policy, University of Maryland Baltimore County, 1000 Hilltop Circle, Baltimore, MD 21250, USA Correspondence should be addressed to John Rennie Short, [email protected] Received 27 November 2011; Accepted 14 March 2012 Academic Editor: Shirlena Huang Copyright © 2012 John Rennie Short.

I will review the major changes in the distribution of the metropolitan population of the United States (US), as revealed by the 2010 data recently released by the US Census. These data allow us to track recent changes and provide the basis for a discussion of longer-term trends identified in previous studies of US cities (Short 2006, 2007) and the city suburban nexus (Hanlon et al. 2010). In brief summary, the paper will show the continuing metropolitanization and suburbanization of the US population. A more nuanced picture will reveal evidence of stress in suburban areas and population resurgence in selected central city areas. Overall, the story is one of a profound revalorization and a major respatialization of the US metropolis. 1. The Broad Picture The mean center of the US mainland population is plotted for each Census decade since 1790. The point marks the central fulcrum of the national population. In 1790 the mean center was located in Maryland and over the years has steadily moved westward in line with the westward shift of population. Between 1970 and 1980, the mean center crossed the Mississippi River, and by 2000 it was located in Phelps County Missouri. By 2010, it shifted further westwards and southward to Texas County in Missouri. The slow, steady shift of the mean center marks the redistribution of the US population to the expanding metro areas of the South and West. Its slow progress, however, reminds us of the continuing population weight of the Northeast. The mean population center now passes through the interior of the country, the so-called heartland. Yet it is a heart with an anemic demographic beat. The population of six counties in this region—Fayette, Marion, Randolph, and Shelby in Illinois and Montgomery and Dent in Missouri— was 144,880 in 1950, rising to only 145,309 in 2010. In much of the rural interior of the US, the story is one of continuing relative population decline as the people move to the city regions. The county that hosted the mean center of population in 2010—Texas County, Missouri—saw only slight population increase from 18,992 in 1950 to 26,008 in 2010. The percentage of persons in the county living below the poverty rate was 24.4 percent in 2010—almost double the national average—and the median household income was only three-fifths of the national average. The rural heartland is losing population and experiencing economic stress. 2. ContinuingMetropolitanization The drift of population to large cities continues. The US census employs the term metropolitan statistical area (MSA) to refer to urban areas with a core area of at least 50,000 and economic links to surrounding counties. Using this statistical, rather than political division of municipal boundaries, it is possible to measure the metropolitanization of the US population. In 1950 the metropolitan population was just over a half at 56.1 percent of the total US population. By 2010 the figure was 83.6. The US population is increasingly and overwhelmingly concentrated in metropolitan areas. More than 90 percent of the country’s entire population growth in the last decade occurred within MSAs. A further 10 percent of the US population lives in micropolitan statistical areas, which contain an urban core of at least 10,000 and, in total, have less than 50,000 population. Only 6.3 percent (versus 6.8 percent in 2000) live outside these two types of urban areas. The US continues to become a more urban and metropolitan society. 2 International Journal of Population Research When we break down the metropolitan areas by size, there are differential growth rates. Table 1 shows the population for different sized MSAs from 1980 to 2010. The greatest growth was concentrated in the smaller sized metro areas. The steady growth of the largest, that is, greater than 5 million population, MSAs, from 1980 to 2000, is now eclipsed by the increasing growth rate of the smaller sized MSAs. This is partly a function of reclassification as smaller urban areas become classified as MSAs but also perhaps indicative of a greater spread of economic activity and population down the hierarchy of MSAs. Table 2 lists the twenty largest MSAs from 1950 to 2010. Notice the stability at the very top of the hierarchy with New York, Los Angeles, Chicago, Boston and Philadelphia and San Francisco keeping their position in the top ten over this 60- year period. There is also change as Sunbeltmetro areas enter the top twenty. There were six metro areas in 2010 that were not part of the top twenty in 1950—Atlanta, Dallas, Denver, Orlando, Sacramento, and San Juan. The inclusion of San Juan, in Puerto Rico, now involves a wider definition of the “national” urban system than one restricted to mainland USA. 3. Central Cities The metropolitan region can be divided into central city and suburban areas. The most significant feature of the last sixty years is the suburbanization of the US population. In 1950 only 23 percent of the US population was living in suburbs. This figure increased to 46.8 percent in 2010. The central city population has remained relatively fixed at around one-third of the entire population. In 2010 it was 36.9 percent. The story of the central city of MSAs is complex. Short and Mussman (forthcoming) plot the individual trajectory of the population size at each successive Census since 1900 of the top 100 cities and identify four model types. The first type of city is steady decline. A typical city in this category is Detroit that experienced a peak of 1.84 million around midtwentieth century and then continuous decline; its 2010 population was 713,777 down from 951,270 in 2000. The city embodies the rise and rapid fall of the older, underbounded, industrial city. Other cities in this category include Akron, Baltimore, Birmingham, Buffalo, Cincinnati, Cleveland, New Orleans, Rochester, Toledo, and Pittsburgh. In these cities the loss of employment caused by the long slow decline of manufacturing is yet to be replaced completely by new forms of economic growth. These cities also bear the brunt of an urban fiscal crisis as the steady loss of population and tax base erodes the revenues of the city. The second type of city is continuous increase. Here the story is of rising economic and population growth and ease of annexation. A typical case is San Jose, CA, a Sunbelt city with an expanding economy based largely on information technology. In 1950 the city population was only 95,280, but by 2010 it was 945,942. Decades of spectacular growth fueled in particular by the Silicon Valley boom in hightechnology and computer-related industries make San Jose one of the most prosperous and economically dynamic cities 3 4 5 6 7 8 9 1900 1910 1920 1930 1940 1950 1960 1970 1980 1990 2000 2010 Population (millions) Decade Figure 1: Population of New York City. in the country. In 2010, San Jose’s median household income was 76,794,comparedtothenationalmedianhouseholdincomeof76,794, compared to the national median household income of 50,046. The city was also able to annex territory, increasing its area size from 17 square miles in 1950 to 177 in 2010. Other examples of this type include San Diego, CA, Las Vegas, NV, and Orlando, FL. The third model type is growth interrupted. Here examples include New York City (NYC), Atlanta, San Francisco, and Seattle. These cities’ upward population trajectory saw some decline before returning to growth and eventually surpassing their previous population peak. Figure 1 plots the trajectory of New York City where the population was relatively flat from 1950 to 1970 before a 20-year decline and then resurgence after 1990. The city’s areal size remained constant at 303 square miles from1950 to 2010. In Atlanta, there was rapid growth from 1950 to 1970 followed by 30 years of decline before population began to up tick again after 2000. In the case of Seattle, population peaked in 1960 then declined before growth returned by the 1990 census. The city was the same size in 2010—84 square miles—as it was in 1960. In this category some annexations did occur, but, especially for the large cities of Atlanta, New York, San Francisco, and Seattle, population growth within stable boundaries was the most important process. Then there is the slowly resurgent city, where previous peaks are not reached, but there is a slow steady return of population. Examples include Boston, Philadelphia, and Washington, DC. In all three cases the areal size of the city remained roughly the same. Washington DC’s population peaked in 1950, then saw continuous decline until 2000 at which point the city’s population began a decade-long resurgence. Cities of this type are big urban areas that did not reach the free fall of continuous decline nor the pronounced returned upward trajectory of the growth-interrupted cities. These cities show signs of population recovery, if not quite to past peaks, at least a bending of the curve from decline to upswing. And in most cases, population growth was not simply the result of city annexation of suburban territory. The four categories are model types, and there is some overlap between the categories. Chicago, IL, for example, lost considerable population from 1950 to 1990, gained over 100,000 between 1990 and 2000, then lost 20,000 between 2000 and 2010 all against a background of fixed areal size since 1960. It falls between steadily declining and resurgent city categories. Other cities in this same liminal categorical space are Philadelphia, PA, and St. Paul, MN. Some cities are located in the continuous growth category despite some International Journal of Population Research 3 Table 1: Percentage of US population in metropolitan areas (MSAs), 1980–2010. MSA size 1980 1990 2000 2010 Over 5 million 20.4 21.1 29.9 24.6 1 up to 5 million 25.2 28.9 27.6 29.5 Up to 1 million 29.2 27.5 22.9 29.5 Nonmetro areas 25.2 22.5 19.6 16.4 Total 100 100 100 100 small reductions from 2000 to 2010; these include Hialeah, FL, St. Petersburg, FL, Santa Ana, CA, and Tulsa, OK. Some of the causes of population resurgences include the growing concentration of high-paying professional jobs in central cities, shrinking US household size that makes suburbs less attractive choices compared to central cities, changing immigration patterns as streams of foreign-born migrants move to central cities. Mikelbank [1, 2] highlights some of the trajectories of change within metro regions and between suburban places. Declining crime rates also make central city living a more attractive proposition. There is also a marked uptick in commercial and residential reinvestment in selected central city areas. Selected central city areas are being revalorized as capital and people move back to the city. The relative position of individual cities is shown in Table 3 that lists the relative size of the largest 20 cities from 1950 to 2010. Two trends can be noted. First, the relative stability of the very largest cities of New York, Los Angeles, Chicago, and Philadelphia that remain within the top ten. Second, the reshuffling of the top twenty as the older industrial areas such as Cleveland, St. Louis, and Buffalo drop out and the more rapidly growing Sunbelt cities such as Houston, San Antonio, Houston, Dallas, and San Jose enter. From 2000 to 2010 three more Sunbelt cities entered the top twenty: Fort Worth, Charlotte, and El Paso. And two rustbelt cities—Baltimore and Milwaukee—dropped out. The changes in rankings embody deeper economic restructuring in the US economy and the associated rise and fall in urban fortunes. 4. Suburban Areas The suburban spread of population continues across the country. Between 2000 and 2010 most MSAs added suburban counties to their metropolitan region. The Pittsburgh MSA, for example, added Armstrong County with a population of 68,941. More dynamic MSAs significantly extended their metropolitan range of influence even further. Atlanta MSA, for example, added 8 new counties with a combined population of almost 160,000 and total area of 2,250 square miles. The suburban frontier continues its outward movement turning even more of the US landscape into a metropolitan society. There is considerable variation within the category of suburbs [1]. Hanlon et al. [3] describe the US suburbs as a place of disparate and divergent realities. At one extreme is what Lang and LeFurgy [4] describe as boomburbs that they characterize asmunicipalities of more than 100,000 that were not the major city of their MSA and experienced double-digit growth for three consecutive decades. Remember, however, that the data reflects different definitions of municipalities. Using 2000 data these authors identified 54 boomburbs with a combined population of 8.9 million. Using the same criteria but updated with 2010 data, only 31 boomburbs were identified with a combined population of approximately 6 million. The rate of red-hot growth has dipped as economic recession, and housing market collapse has undercut very rapid suburban growth. Even the experience of particular boomburbs has slumped since the housing market collapse. Flagler County in Florida, part of the Palm Coast MSA, grew an astonishing 92 percent between 2000 and 2010, a function of the housing boom of 2001–2007. Since 2008 however the housing market has collapsed with rising unemployment and foreclosure rates. The poverty rate in the country has increased by almost fifty percent from 2000 to 2010, from 11.3 percent of all persons to 15.1 percent. Across the metropolitan landscape, the growth in the former boomburbs has stalled due to the housing crisis. At the other extreme, there is also what Hanlon [5] describes as “suburbs in crisis.” These are defined as suburbs that witnessed population loss and economic retrenchment. Her analysis was based on 2000 data. We can get a more recent snapshot by updating the story of just one of these suburbs. Dundalk, an industrial suburb in the Baltimore MSA, experienced increased poverty and declining income from 2000 to 2010. The poverty rate for individuals increased from 9.2 percent to 12.4 percent in 2010, while the median household income fell from 46,035to46,035 to 45,088. The older industrial suburbs continue to decline. Over the past half century, the suburban experience has diverged. The difference between rich and poor suburbs has substantially increased. In the past decade the rapid growth of boomburbs has deflated due to the housing crisis and the difference between rich and poor suburbs widens as poverty continues to rise in the poorer suburbs. 5.Megalopolis We can consider some of the changes within metropolitan areas by considering one case study. One of the largest contiguous areas of metropolitan counties is what Jean Gottmann [6] first identified as Megalopolis, a region spanning 600 miles from north of Richmond in Virginia to just north of Portland in Maine and from the shores of the Northern Atlantic to the Appalachians. A profile of the region from 1950 to 2000 was undertaken by Short [7]. The region now includes the consolidated metropolitan areas of Washington-Baltimore, Philadelphia, New York, and Boston and covers 52,000 square miles. In 2000 the population of this giant urban region was 40.6 million. By 2010 it has increased to 44.6 million with in situ growth and new counties being added because of spreading metropolitan influence. It is the single biggest metropolitan concentration of population. In both 2000 and 2010 it contained just over 14 percent of the entire US population. 4 International Journal of Population Research Table 2: The twenty largest metropolitan areas in the US by population, 1950–2010.

CMSA: combined metropolitan statistical area. CSA: combined statistical area. Within this region three trends can be noted from 2000 to 2010. First, the urban core regions have retained their relative demographic position. In 2000 the combined population of Boston, New York, Philadelphia, and Washington was 10.64 million and by 2010 this increased to 10.88 million. All these cities had established producer services, while Baltimore, with a relatively large manufacturing base, declined from 651,154 in 2000 to 620,961 in 2010, reflecting the broader continuing shift of the dynamics of the US economy away from manufacturing to producer services. Second, suburban dominance continued as the percentage of the regions’ total population increased from 72 to 74 percent. Compared to earlier decades, however, the central city-suburban distribution now seems more stable as the years of rapid suburban growth and central city decline are now replaced by a more varied picture of resurgence in selected city centers with a leveling off in rapid suburban increases. There are still areas of rapid growth especially in the southern part of Megalopolis that includes counties fringing the Washington Baltimore MSAs. Loudon County in the northern Virginia suburbs of the Washington MSA, for example, saw an absolute increase from 169,599 in 2000 to 312,311 in 2010. Elsewhere in this particular growth region, rapid growth slowed. Howard County, Maryland, for example, saw a huge population increase from 23,110 in 1950 to 247,842 in 2000 but only a slight increase to 287,085 by 2010. The growth was effectively a filling-in of the commuting corridor between Washington DC and Baltimore.Many of the former high growth suburbs are now built out. Throughout the region there was also evidence of decline in some of the older inner suburbs, what Puentes and Warren [8] describe as first suburbs.

    The Age of Adolescence

    Children, LiteratureThe Age of Adolescence Ellen Handler Spitz Jepp, Who Defied the Stars by Katherine Marsh Hyperion, 385 pp., $16.99 THIS PAST SUMMER, with a transfixed ten-year old by my side, I stood in Madrid’s palatial Museo Nacional del Prado, face to face with Diego Rodríguez de Silva y Velázquez. We gazed at the self-portrait of this grand master of the bravura brush stroke, gripping his palette in his left hand and wielding a paintbrush in his right, and we admired the wasp-waisted five-year-old Infanta Margarita who poses pertly before him in the endlessly fascinating Las Meninas. I pointed out diminutive King Philip IV and his queen, caught in their black-rimmed mirror just left of a coffered door, which opens mysteriously onto a dazzle of light. But about the court dwarfs—Maria Bárbola, with her bulbous head and short arms, and Nicolasito Pertusato, who kicks the lazy mastiff—I had little to say. A barrage of earnest questions from the child beside me exposed a glaring lacuna in my art history background. Why are they there? What are they doing? Were they servants, too? Why did the Spanish court keep them? As a girl, Katherine Marsh was similarly mesmerized by the dwarfs in Velázquez’s masterpiece, and by those that appear in other paintings of the period. To explore their plight, she conceived Jepp, Who Defied the Stars—her latest venture into books for young readers. Jepp is a first-person narrative, an historical novel set in the Spanish-ruled Netherlands of the late sixteenth century and in Denmark. Permit me a sigh of discontent that Las Meninas is nowhere to be found between the covers of her book, for its reproduction would have served as a model for the way that works of visual art can spark literary creation. This very painting, after all, inspired Oscar Wilde’s heartbreaking tale of an Infanta who laughs a little dwarf to death on her twelfth birthday. Throughout Jepp, Marsh’s well-imagined title character and her other court dwarfs provide answers to some of the questions raised by Las Meninas. After a happy childhood in a village near Utrecht, Jepp arrives at the Spanish court of Coudenberg in Brussels to become a court dwarf. He is brought there by a strange courtier, Don Diego (who later proves to be Jepp’s absent—and deceased—father’s younger brother). At fourteen, the boy is no taller than he was at seven. In Brussels, the Infanta treats Jepp and his cohort handsomely, but rather like toys or pets. She expects them to amuse and divert her, but they are not regarded as fully human. Courtiers and servants shamelessly touch their bodies ad libitum, costume them at will, and make them suffer a host of indignities (Jepp’s first is to jump out of a pie served to the Infanta). Far more horrifyingly, a delicate blond dwarf named Lia, Jepp’s friend, is victim of a secret rape by a courtier named Pim. Lia persuades Jepp to accompany her in an attempted escape so as to bear her baby in freedom, but she dies in childbirth. While it successfully conveys the degradation to which the dwarfs were subjected historically, the inclusion of this dark episode in a book for young readers may expose some pre-teens to an excess of depravity. Before her violation, Lia enjoys a close friendship with Robert, a kindly Hagrid-like giant who is also retained by the Infanta as a grotesque, and the court immediately assumes that it was he who made her pregnant. Marsh’s florid evocation of this huge male copulating with this tiny female, even though it proves false, may seem to corroborate widespread childhood fantasies of sexual acts as aggressive conquests. Eventually Jepp is banished from the Infanta’s presence, and his story continues while he is en route to another castle, Uraniborg in Denmark; he is transported there from Brussels in a cage reminiscent of the contraption occupied by the outsized Lemuel Gulliver in Brobdingnag. The latter parts of Marsh’s novel find him under the aegis of the famous astronomer Tycho Brahe, an eccentric island-dwelling, silver-nosed scientist, whose beer-guzzling moose attends dinner in his castle. Jepp is made to eat on the floor under the table at Tycho’s feet. What makes all this particularly poignant in the context of “young adult” fiction is that Jepp and his cohort—diminutive persons who appear neither adult nor child—can so easily stand in for the book’s intended readers. Suffering extreme humiliation, Marsh’s characters not only teach historical injustice but, closer to home, they mirror the manipulation, objectification, and failure to be taken seriously that many teens and pre-teens feel they endure under uncomprehending adults. The dwarfs in Marsh’s novel, moreover, are propelled by their frustrations into unproductive behaviors: at Coudenberg, one preens constantly before a looking glass, and another is addicted to hippocras. Under conditions of oppression, their relations with one another are tarnished by rivalry and suspicion. Thus the dwarfs become, in Marsh’s skillful hands, supremely sympathetic figures. In pre-adolescence, our bodies morph, betraying us day by day. Alien to ourselves as well as to others, we yearn to shoot up instantly or to stop growing altogether—to shrink back into warm childhood, where right and wrong lay neatly folded in separate piles on a shelf. But the door to childhood is shut. Adolescents are newly encased—like Jepp—in bodies that seem too small (or too large) but never a match for what is inside them, which nobody else can see. Marsh’s characters capture many near-ubiquitous experiences of this particular stage of life. Jepp exists in relative emotional isolation: his body, psyche, and surrounds feel intermittently out of sync. Features of Marsh’s plot parallel with psychological acuity deep levels of pre-adolescent experience. Haunted in a fatherless household by the mystery of his paternity, Jepp longs to find his father. The desire to find one’s true, lost parents animates, as we know, not only the fantasy lives of youth who have endured bereavement, abandonment, and adoption, but also of many a discomfited teen. During much of Marsh’s story, Jepp narrates his adventures while traveling like a small animal in a cage. A rough keeper named Matheus tosses in his daily food, and he knows not his destination. Again, modern echoes abound: despite the plethora of insignificant choices accorded them, young people’s lives are not in their hands, and they often feel cooped up in prisons not of their making. Marsh’s doubled narration (Jepp reminiscing about Coudenberg on his way to Uraniborg) mirrors the way youth balks haltingly at the regimentation of cultural clock time (alarm buzzers, class bells), their jerky back-and-forth between outer and inner worlds captured so brilliantly by Bill Watterson in his Calvin and Hobbes comic strips. Marsh evokes this wonderfully, with all its puzzling confusion. As one reads Jepp, Who Defied the Stars, present and past entangle just as childhood and adulthood spar. Over the course of this fine novel, what matters principally is that a meek, naïve boy, easily manipulated and duped to the point of endangering himself and his friends, develops—despite his handicap—into a more mature character, capable of assuming responsibility for his choices and responding finally to the devotion of a fiercely independent young woman. Jepp progresses from adoration of frail Lia to love for Magdalene, the daughter of Tycho Brahe, who is not a dwarf. In an image that reverses the Robert-Lia fantasy, Magdalene towers over Jepp, and from her he learns the necessity of accepting fate while acting “out of love rather than fear.” Caught between worlds, Jepp not only grows up, he becomes real. He exits forever the world of Las Meninas, but this time with life and with hope. Ellen Handler Spitz is Honors College Professor at the University of Maryland (UMBC).

    Helping Verbs, English GrammarThis lesson was developed by John Nelson and Tymofey Wowk, 2012 Making English Grammar Meaningful and Useful Mini Lesson #4 Helping Verbs – 5 Grammatical Functions The purpose of this lesson is to list the ways in which Helping Verbs are used in English tenses. English is not a heavily inflected language. Instead, it makes use of Helping Verbs. Helping Verbs are verbs that have grammatical functions in subject-verb combinations without adding semantic meanings to the sentences in which they are found. Chart #1 presents the helping verbs used in the 12 English tenses. Chart #1 – English Helping Verbs Simple Tenses Continuing Tenses Before Tenses Continuing Before Tenses Future Tenses will will be will have will have been Present Tenses do does am is are have has have been has been Past Tenses did was were had had been In spoken English, Helping Verbs are frequently reduced and contracted with other words, but they have 5 very important Grammatical Functions. 1. Helping Verbs indicate the Kind of Tense used in an utterance. Continuing Tenses use the verb ‘BE’ as helping verbs. Before tenses use the verb ‘HAVE”. Simple tenses use the verb ‘DO’ in negatives and questions. 2. Helping Verbs indicate the Time – Past, Present or Future – when the events described by the verb took place. 3. English Negative utterances are formed by placing the word ‘NOT’ after the initial Helping Verb as illustrated in Chart #2. Frequently the Helping Verb and ‘NOT’ are contracted. This lesson was developed by John Nelson and Tymofey Wowk, 2012 Chart #2 Using Helping Verbs in Negative Sentences Simple Tenses Continuing Tenses Before Tenses Continuing Before Tenses Future Tenses I will not walk home. I will not be walking home. I will not have walked home. I will not have been walking home. Present Tenses I do not walk home. I am not walking home. I have not walked home. I have not been walking home. Past Tenses I did not walk home. I was not walking home. I had not walked home. I had not been walking home. 4. English Questions are formed by inverting subject-verb word order. In nearly all cases, it is a Helping Verb that comes before the subject to form a question as illustrated in Chart #3. Chart #3 Using Helping Verbs in Questions Simple Tenses Continuing Tenses Before Tenses Continuing Before Tenses Future Tenses Will you walk home? Will you be walking home? Will you have walked home? Will you have been walking home? Present Tenses Do you walk home? Are you walking home? Have you walked home? Have you been walking home? Past Tenses Did you walk home? Were you walking home? Had you walked home? Had you been walking home? 5. English requires sentences to have Subjects-Verb Agreement regarding singularity and plurality. In most instances, it is the Subject and the Helping Verb which must be in agreement

    Dependent Clauses, Phrases, Adjective Clauses, Noun Clauses, Adverb Clauses, English GrammarThis lesson was developed by John Nelson and Tymofey Wowk, 2012 Making English Grammar Meaningful and Useful Mini Lesson #12 Clauses and Phrases: The Difference is Simple The purpose of this lesson is to explain the difference between Dependent Clauses and Phrases, and to present the three basic kinds of Dependent Clauses. A Clause is a group of words that go together to form a unit. It has one essential characteristic; a Clause must have a Subject-Verb Combination. A Phrase is a group of words that go together, but which does not have a Subject-Verb Combination. Sentences are composed of at least one clause which gives a complete idea. Dependent Clauses are those that do not communicate a complete idea. They are connected to an independent clause in some way. English has 3 kinds of Dependent Clauses. Each does the same thing as a particular part of speech and, therefore, each is named for a part of speech. There are Adjective Clauses, Noun Clauses and Adverb Clauses. Adjectives describe nouns; Adjective Clauses also describe nouns. However, adjectives generally come before the nouns they describe, while Adjective Clauses follow the nouns they describe. The following sentence contains both an Adjective and an Adjective Clause. They each describe the noun ‘man’. He is the young man who you met yesterday. Nouns are used as Subjects or Objects of sentences. Noun Clauses are also used as Subjects or Objects of sentences. These two sentences contrast the use of a Noun and a Noun Clause. Both are objects of the sentences in which they are used. The teacher asked a question The teacher asked if the students understood. Adverbs indicate time or reason among other things. Adverb Clauses indicate the same information. These two sentences contrast the use of an Adverb and an Adverb Clause. He did his homework late in the evening. He did his homework after he came home from the party. This lesson was developed by John Nelson and Tymofey Wowk, 2012 ELLs will find it helpful to contrast Dependent Clauses with similar Phrases. The following sentence pairs illustrate these differences. An Adjective Clause and an Adjective Phrase: I met the man that teaches the grammar class. I met the man teaching the grammar class. A Noun Clause and a Noun Phrase: He asked me if I would help him study. He asked me to help him study. An Adverb Clause and an Adverb Phrase: The game was cancelled because it rained. The game was cancelled because of the rain. ELLs find Clauses and Phrases confusing and mysterious, but they do not need to be. Learners can be taught to recognize and produce word groups with and without Subject-Verb Combinations. Once this is mastered, competence using these 3 kinds of clauses and phrases is more easily accomplished. Understanding their basic constructions and relating them to simple parts of speech will enable ELLs to produce Dependent Clauses and Phrases easily and use them accurately

    Adverb Clauses, English GrammarThis lesson was developed by John Nelson and Tymofey Wowk, 2012 Making English Grammar Meaningful and Useful Mini Lesson #14 Adverb Clauses: Don’t Use Future Tense The purpose of this lesson is to describe Adverb Clauses and illustrate a few characteristics of their use. Adverb Clauses provide information about the Main Clause of the sentences in which they are found. They are the only kind of Dependent Clause that is not a part of the Main Clause. They can be found either before the Main Clause or after it. There are a few important aspects to learn about them. Adverb Clauses and Adverb Phrases have several meanings, which are illustrated in the following chart. Notice the differences in some cases between the CONNECTORS used with Adverb Clauses and those used with Adverb Phrases. Meanings of Adverb Clauses and Phrases Meaning Adverb Clause Adverb Phrase Time The game was played after it stopped raining. The game was played after the rain. Reason The game was not played because it rained. The game was not played because of the rain. Purpose The game was delayed so that the field could dry. The game was delayed in order to let the field dry. Contrast Both teams came to the game although it rained. Both teams came to the game in spite of the rain. Since Adverb Clauses are not found within the Main Clause, they can be found either before it or after it. All of the sentences in the chart above could be expressed with the Adverb Clauses and Phrases coming before the Main Clauses. When an Adverb Clause precedes the Main This lesson was developed by John Nelson and Tymofey Wowk, 2012 Clause, it is preferable to put a comma between the Adverb Clause and the Main Clause. When the Main Clause comes first, a comma is not needed because the Adverb Clause Connector indicates the beginning of the Adverb Clause. (For example, notice the 3 commas in the preceding sentences.) Adverb Clauses have one characteristic that ELLs need to be made aware of. The Simple Future Tense cannot be used in an Adverb Clause when the clause expresses a future time. The Simple Present Tense or the Present Continuing Tense is used instead. Note the following examples: 1. Tomorrow, he will drive home. Tomorrow, he will wash his car. 2. Tomorrow, he will drive home and he will wash his car. 3. Tomorrow, he will drive home and wash his car. 4. Tomorrow, after he drives home, he will wash his car. 5. Tomorrow, he will drive home before he washes his car. All the examples in these sentences will take place tomorrow. When the two ideas are presented in separate sentences, as in example 1, they employ the Simple Future Tense. When they are combined by a Simple Connector, as in sentence 2, the Simple Future Tense is used with both clauses. Even in Sentence 3, where the Simple Connector connects phrases, the Simple Future Tense is used with both verbs. However, Adverb Clauses are used in both sentences 4 and 5. Notice that the Simple Present Tense is used in both Adverb Clauses in both sentences despite the obvious future meaning of the clauses. Future Tenses cannot be used in Adverb Clauses of time

    SEMANTICALLY RICH, POLICY BASED FRAMEWORK TO AUTOMATE LIFECYCLE OF CLOUD BASED SERVICES

    Managing virtualized services efficiently over the cloud is an open challenge. Traditional models of software development are very time consuming and labor intensive for the cloud computing domain, where software (and other) services are acquired on demand. Virtualized services are often composed of pre-existing components that are assembled on an as-needed basis. We have developed a new framework to automate the acquisition, composition and consumption/monitoring of virtualized services delivered on the cloud. We have divided the service lifecycle into five phases of requirements, discovery, negotiation, composition, and consumption and have developed ontologies to represent the concepts and relationships for each phase. These are represented in Semantic Web languages. We have developed a protocol to automate the negotiation process when acquiring virtualized services. This protocol allows complex relaxation of constraints being negotiated based on user defined policies. We have also developed detailed ontologies to define service level agreements for cloud services. To illustrate and validate how this framework can automate the acquisition of cloud services, we have built two applications from real world scenarios. The Smart cloud services application enables users to determine and procure the cloud storage service that matches most of their constraints and policies. We have also built a VCL broker application that allows users to automatically reserve the VCL Image that will best meet their requirements. We have developed a framework to measure and semi-automatically track quality of a virtualized service delivery system. The framework provides a mechanism to relate hard metrics typically measured at the backstage of the delivery process to quality related hard and soft metrics tracked at the front stage where the consumer interacts with the service. While this framework is general enough to be applied to any type of IT service, in this dissertation we have primarily concentrated on the Helpdesk service and include the performance rules we have created by mining Helpdesk data

    EFFECTS OF DISTURBANCE AND A DOMINANT CONSUMER ON STREAM COMMUNITY ASSEMBLY: EXPERIMENTAL AND OBSERVATIONAL EVIDENCE

    No full text
    Without understanding changes in aggregate and compositional properties, it is possible to misinterpret mechanisms driving community variability. Changes in patterns of variability can be caused by independent and interactive effects of biotic and abiotic drivers. In an experimental study, I manipulated the presence of a dominant detritivore (P.gentilis) and disturbance (drying). I found that disturbance lowered aggregate variability and the presence of P.gentilis lowered compositional variability, but only in the absence of disturbance. In an observational study, I created an index describing relative likelihood of disturbance (system-level drought) for multiple watersheds and tested the impacts of the likelihood of disturbance and the presence of P.gentilis on aggregate and compositional variability. Disturbance tended to increase aggregate variability and decrease compositional variability, but only in the absence of P.gentilis. The results of both studies indicate that there may be an interaction between biotic and abiotic drivers that can significantly change community dynamics

    Should Head Start Centers Have Naps? An Experimental Study Examining the Effects of Nap Policy on Classroom Behavior in Preschool Children

    No full text
    As preschool teachers and administrators strive to meet academic standards and make school schedules as efficient as possible, they differ in their opinions and approaches to daytime naps. To some extent these differences reflect a lack of authoritative data on how naps affect classroom and learning behaviors. The present study is the first known experimental study to directly examine the effects of eliminating naptime on preschool children's behavior. In general, results were mixed. Behavioral observations in the classroom indicated no significant differences in children's behavior and even suggested some improvement in behavior after naptime cessation. Teacher and parent reports, however, indicated that children's inattention increased after nap elimination. One explanation for disparate results may be that negative effects of nap cessation emerge later in the school day and/or at home, though one must consider study limitations before confidently reaching this conclusion. Exploratory analyses revealed that children slept less overall after nap elimination, though there was some evidence suggestive of increased nocturnal sleep efficiency. This efficiency may in part explain children's lack of differences in observed disruptive behavior and irritability after nap elimination. The present study highlights the need for future studies to examine the effects of naptime cessation utilizing objective behavioral assessments at school and at home as well as instruments to examine sleep architecture

    Cell Response to Hydrogel Tissue Scaffolds

    Tissue Engineering is evolving as one of the most promising therapies in regenerative medicine. Biomaterials are attractive substrates for tissue-engineering applications because they are biocompatible, can be biodegradable, and can be fabricated from a variety of materials. The ideal biomaterial substrate mimics native extracellular matrices to regulate cellular function, provide physical structure, and allow the diffusion of vital solutes. Cell morphology, proliferation, and differentiation are linked to substrate geometry and physical properties. We show that the dimensionality (2D vs 3D) of a substrate more strongly influences neuronal morphology than substrate stiffness. We also correlated GRGDY-modified alginate gel composition with gel stiffness and cell behavior: increased GRGDY and alginate concentrations resulted in increased gel stiffness and density of adherent cells. While increased calcium also increased gel stiffness, cell density was optimal at an intermediate calcium concentration. This work adds towards our understanding of optimizing scaffold properties to direct cell response
