Optimizing of Traffic-Signal Timing Based on the FCIC-PI—A Surrogate Measure for Fuel Consumption

Optimizing signal timing improves sustainability metrics (e.g., fuel consumption or “FC”). Historically, traffic agencies have retimed signal timing to improve mobility measures (e.g., delays). However, optimizing signals to reduce delays does not necessarily mitigate sustainability measures. Hence, this study introduces an approach that integrates a newly derived surrogate measure for FC, traffic microsimulation software, and a stochastic genetic algorithm. This approach optimizes signal timing to reduce the surrogate measure and reduce sustainability metrics. This study also evaluated the impact of heavy vehicles’ presence in a fleet on signal timing and FC savings. A 13-intersection arterial on Washington Street in the Chicago metro area served as a case study. Optimized signal timing delivered solutions that balanced both sustainability and mobility. The estimated excess FC savings ranged between 8 and 12% under moderate operating conditions, with no heavy vehicles, compared to the initial signal timing. The savings reached up to ~14% when many heavy vehicles existed on the side streets. Most of the improvements came without worsening traffic-mobility efficiency, which shows the possibility of a fair tradeoff between mobility and sustainability. All optimization scenarios showed that a slightly longer cycle length than the one implemented in the field is required to reduce FC.

The KISSinger of Death: Henry Kissinger and the Letelier-Moffitt Assassination

On September 21st, 1976, Orlando Letelier was assassinated in the streets of Washington, DC. The murky story of the assassination has slowly emerged in the decades since, revealing the key roles of Chilean dictator Augusto Pinochet and Operation Condor. However, with the level of intelligence available to the United States about the Chilean dictatorship, how was the assassination able to take place at all? Was the United States complicit? This paper illuminates the role of the US Secretary of State, Henry Kissinger, in the Letelier-Moffitt assassination by investigating declassified documents from US National Security Archive from the months leading up to the murder. While the existing historical record does not show that Kissinger was directly involved in the Letelier assassination, Kissinger could have prevented this tragedy and failed to. I suggest a variety of possible explanations as to why Kissinger failed to act; however, the full truth remains riddled with secrecy and ambiguity. Until the full historical record is revealed and efforts are made to unshroud the mystery of this story, there will be barriers to believing the words of the government, barriers to collective healing, and there will be barriers to knowing history itself.

Forgiving the Unforgivable

Forgiving the Unforgivable Anna Badkhen (bio) oklahoma to texas On a Monday in early August I find myself spooning soil from Geronimo's grave at a prisoner-of-war cemetery in Oklahoma into a double Ziplock bag I bought at Target. I will carry this soil, by car and bus, to Guachochi, a town in the Sierra Madre Occidental. There, three Mexican sisters who have recently traced their ancestry to the famous Apache medicine man are about to hold a Ceremonia del Perdón—Ceremony of Forgiveness. The soil is my gift to them. Geronimo's grave is inside Fort Sill, a US Army base, so I must first stop at the visitor center to obtain a pass. The United States staked out Fort Sill in 1869, as a staging ground for punitive raids against the Native Americans who had survived deportation to Indian Territory, and even though the base dates back more than a hundred years, its visitor center bears the ubiquitous hallmarks of military efficiency that scream temporariness: insulated white metal wall panels mounted on a concrete foundation and facing a parking lot paved with ankle breaker gravel. I have seen structures and parking lots exactly like this on US military bases in Iraq and Afghanistan, which also were staging grounds for raids into quasi-occupied lands; most of those are now gone. Inside the visitor center, a jovial military policeman hands me Form 118a, Request for Unescorted Installation Access to Fort Sill. This is to ensure somehow that I am not a terrorist. I enter my full name, date of birth, driver's license number, social security number, gender, race. Under "purpose of visit" I check "other." Beef Creek Apache Cemetery was established in 1894, the year Geronimo and 341 other surrendered Chiricahua Apaches—adults and children—were transferred from a prisoner-of-war camp in Florida to Fort Sill under military escort. Here, in the foothills of the Wichita Mountains, Geronimo's insurgency against white colonists came to an end. It had begun in 1851, when Mexican soldiers massacred more than a hundred women and children in Geronimo's encampment, among them his mother, his first wife, and all three of his young children. At Beef Creek, rows of identical upright headstones of white marble poke out of a manicured sloping field of green; think Arlington Cemetery minus the color guard. Among this impersonal personal misery, Geronimo's tomb stands [End Page 1] out, a pyramid of granite boulders perhaps five feet tall, topped with a stone eagle. A small grove of white hibiscus and fragrant abelia screens it slightly from the rest of the burial ground. Geronimo died technically of pneumonia but ultimately of the humiliation that accompanied his imprisonment. To be a POW of the United States back then was different than at Guantánamo: Apache prisoners could set up villages within the perimeter of the army base. They could marry and raise children and bury them. I check the stones. One couple lost three children in five years. Many grave markers have only one date. Some Apache prisoners got to travel outside the wire. With Pawnee Bill's Wild West Show, which advertised his cameo as "The Worst Indian That Ever Lived," Geronimo hawked his legend at county fairs. And he was one of six Native men to ride horseback in Teddy Roosevelt's inaugural parade through the streets of Washington, DC, in 1901. When someone asked Roosevelt why he chose this "greatest single-handed murderer in American history" to join his parade, the president replied, "I wanted to give the people a good show." To the left of Geronimo's is the grave of the sixth of his nine wives, Zi-Yeh, who died in 1904 at the age of thirty-five, of tuberculosis. To the right, the grave of their daughter Eva Geronimo Godeley, who was forced to attend one of the Indian boarding schools the US government had created to strip Native children of their roots; her school was almost two hundred miles away. She was twenty-one when she died, in 1911. Eva's daughter, Evaline, died at birth the year previous; she is buried here, too. Geronimo was...

Gentrifiers, distinction, and social preservation: A case study in consumption on Mount Pleasant Street in Washington, DC

Mount Pleasant, a neighbourhood of Washington, DC that has experienced several decades of residential gentrification (Gale, 1980; Modan, 2007; Williams, 1988), nonetheless possesses a commercial corridor where local stores far outnumber boutique retail and corporate chain outlets. Its situation challenges a critical strain within the commercial gentrification literature that emphasises the likelihood of retail displacement during the gentrification process and characterises gentrifier consumers as primarily interested in retail outlets that are familiar or carefully designed to suit their taste. This study investigates gentrifiers’ consumption practices in Mount Pleasant to ascertain how they differ from those of peers in neighbourhoods where gentrification has followed a more typical trajectory. Using theories of distinction (Bourdieu, 1984) and social preservation (Brown-Saracino, 2009), I argue that many local gentrifiers, contradictorily, seek to accrue cultural capital by consuming ‘authentic’ local culture and products while paying attention to the costs of turnover and displacement.

Latino Immigrants in North Carolina

In the second edition of her insightful book on Latino migration to North Carolina, Hannah Gill of the University of North Carolina’s Institute for the Study of the Americas and the Center for Global Initiatives, recalls an anti-immigrant protest rally that occurred in April 2008 in Washington, the county seat of Beaufort County, North Carolina. More than one hundred people walked through the streets of Washington to attend a meeting of the Beaufort County commissioners, which had been called to discuss the cost of undocumented immigrants on county health and social services.

The F Street Mess: How Southern Senators Rewrote the Kansas–Nebraska Act by Alice Elizabeth Malavasic

Reviewed by: The F Street Mess: How Southern Senators Rewrote the Kansas–Nebraska Act by Alice Elizabeth Malavasic Andrew F. Hammann (bio) The F Street Mess: How Southern Senators Rewrote the Kansas–Nebraska Act. By Alice Elizabeth Malavasic. (Chapel Hill: University of North Carolina Press, 2017. Pp. 280. Cloth, $29.95.) Alice Elizabeth Malavasic tells the story, and indeed the backstory, of the Kansas–Nebraska Act, a piece of legislation passed in 1854 and commonly cited by historians as the catalyst of the rise of the Republican Party and the sectional discord that became civil war. Malavasic's narrative, which spans the years 1837 to 1861, recounts how a tight-knit group of Congressmen who lived together on F Street in Washington, DC—David Atchison of Missouri, Andrew Butler of South Carolina, and [End Page 605] Robert Hunter and James Mason of Virginia—came to play a decisive role in proposing and defending the most controversial element of the Kansas–Nebraska Act: the repeal of the Missouri Compromise's 36' 30" line, which banned slavery north of this latitude in the Louisiana Territory. Malavasic is not the first historian to point out that the F Street Mess wielded considerable power in shaping and passing a piece of legislation associated, most commonly, with Senator Stephen Douglas of Illinois. She acknowledges this by pointing to past works by Michael Holt, Allan Nevins, David Potter, and, most recently, Rachel Shelden in Washington Brotherhood: Politics, Social Life, and the Coming of the Civil War (Chapel Hill, NC, 2013). What The F Street Mess adds to existing scholarship, Malavasic contends, is a deeper understanding of the role that the "group dynamic" among the four messmates played in constituting their outsized collective influence (14). Malavasic meticulously guides readers through the Kansas–Nebraska debates' complex politics and historical context. She explicates, often with notable clarity, a range of legal arguments made in favor of, or against repeal of, the 36' 30" line and connects these positions to the partisan agendas and personal interests (mostly land speculation and reelection) of the men who formulated them. To keep things lively, Malavasic inflects her delivery with moments of literary flair meant to conjure a sense of historical atmosphere. A good example appears in the lead paragraphs of Chapter 4 where she describes the commencement of the 1853–1854 Congressional session. Malavasic begins by panning around the vast, ornate Senate chamber and establishing each F Street Mess member's location within it. She then shifts the reader's gaze to the "small unadorned" and "spindly" current-bill box on whose bottom shelf a new Kansas–Nebraska bill would most likely soon be placed (81). With a sense of foreshadowing, she finally adds, "whether it would be one of the few [bills] to make it to the narrow top shelf" before the session's end was "uncertain"; "what it would look like if it did" was quite uncertain as well (82). The most intriguing aspect of the book lies in its overall conceptualization. Like Rachel Shelden, Malavasic points out that political histories can give insufficient attention to the ways that personal relationships shaped the political process. More commonly emphasized factors such as "ideology, party, and region" mattered, she readily acknowledges, but in certain instances "friendships" forged and sustained outside of [End Page 606] legislative halls overshadowed these factors in determining the laws produced within them (17). Malavasic contends that the Kansas–Nebraska Act, specifically the Missouri Compromise repeal article, was just such an instance. As valid and intriguing as Malavasic's framework is, it connects to an unsteady aspect of the book. While The F Street Mess provides thoughtful biographies of the individual messmates, it does not deliver a full enough sense of the Mess's group dynamic—the book's purported argumentative hinge—or the interpersonal elements that comprised it. In the first and second chapters, for instance, Malavasic makes much of John Calhoun being key to understanding the F Street Mess's cohesion and influence—"they were the heirs of Calhoun," she asserts (59). Yet these chapters, and subsequent ones, leave readers wanting deeper and more specific explanations of how each member personally understood this "inheritance" and how these understandings...

Philip Roth: Face to Face

Philip RothFace to Face Ira Nadel (bio) It was Chancellor Blvd. that brought me to Philip Roth. Stash's Anchor Inn on Hawthorne Avenue and the Weequahic Diner at the corner of Elizabeth and Hawthorne avenues also helped. My mother, Newark-born, would often return to visit her old haunts and I would troop along to enjoy a shrimp cocktail at Stash's or dessert at the diner. Often, we went shopping at Bamberger's department store for school clothes. In distant Rahway, the styles and choice were just not au courant for the suburban primary grades. My mother's preferred parking lot was next to the Empire Burlesque Theatre on Washington Street, a block from Market, and I vividly recall studying the posters of the scantily clad women just as Portnoy remembers in his complaint. The Adams Theatre, run by Harold Minsky, was another local attraction, but it was a few blocks away. The Empire and Adams, however, both had to close in 1957 because of new anti-burlesque bylaws. One night in January 1957, twenty-one of Newark's most talented performers were arrested. South Orange, West Orange, and Irvington were not mythical but actual places for me with swim clubs, cousins, and even dates. Neil Klugman's world of Goodbye, Columbus was for me a place to touch and taste and linger. Connections with Roth existed even before I learned that he and I were both born in Newark's Beth Israel Hospital, although a decade apart. I Roth and I first met formally when I was an undergraduate at Rutgers (New Brunswick, not Newark). I soon began to read every new Roth work and vividly recall attending a seminar he gave for some fifty—or was it sixty?—at Princeton. Crowded into a large, oak-paneled room, I still remember his wry answer to what was back then an archetypal question: "do you write with a pen or with a typewriter?" He characteristically deflected a reply, choosing [End Page 105] instead to emphasize the daily struggle to write well, something borrowed from the world of Henry James, but expressed with Newark style. Click for larger view View full resolution Copyright The Star Ledger; NJ Advance Media. Published June 11, 1954. My doctoral defense at Cornell unexpectedly continued my engagement with Roth. It was largely devoted to only one subject and it was not "Renunciation in the Works of Thomas Carlyle and George Eliot." Portnoy's Complaint took precedence, having appeared only a few months before. Of course, I had studied [End Page 106] it carefully and considered myself a partial expert, confidently explaining to my New Jersey born committee member, M. H. Abrams, that it might indeed signal a new and enthralling urban Romanticism. He wanted to know more. Roth after graduate school became a repeated pleasure, although I did not begin to write about him until years later. Articles, conferences, and a reference book expanded my own early understanding of identity politics for I, too, had spent listless hours in Hebrew School, wandered about Weequahic Park, and hoped to go to Bucknell—but Roth also taught me about the complexities of an American Jewish identity and conflicts with the social world one inhabited. Attracted to his language, themes, and carefully detailed settings, I sought to know more and his essays taught me what questions to ask. Although there was halting correspondence over the years (most often with his legal representatives), we did not meet again until his eightieth birthday celebration at the Newark Museum. Offering congratulations while in the swirling crowd, he stared at me for a moment, aware I was about to undertake a critical biography, before saying, with a tone of incredulity, "You? You're Ira?" "Yes," I replied, unable to utter another word before he was swept away by his ardent admirers. I took solace in being photographed with Blake Bailey. Without time for an incisive question, or another compliment that evening, I became an observer, understanding the importance of boundaries as he refused requests to sign books and even to speak to certain intrusive individuals. Roth was happiest entering with the Weequahic High School marching band and sitting with Edna...

The Meaning of Membership in a Group and the Gifts of Service in a Volunteer Organization

Although many of us conceive of service as an altruistic function that may distract us from our personal needs, I suggest that service may actually be quite a selfish endeavor that not only ensures our survival but also leads to generativity and abundance , for us and for the groups to which we belong. My day job is addiction psychiatrist and group psychotherapist. I have chosen to treat my patients in groups, based on my belief that addictions, as well as most mental illnesses, are diseases of isolation. We know from the substantial body of knowledge that composes attachment theory that the failure to attach during infancy and childhood results in death or severe disability. Healthy membership in our families of origin prepares us to become members of society, which comprises a variety of groups, each with its own boundaries, roles, authority structure, and tasks. Some of these groups have the primary task of generating income. Service in these groups typically involves taking the role of employee, and the reward for this service is financial. Such groups have boundaries that define who is employed, who is promoted, and who is fired. Different employees are given differentiated tasks that are carried out within a defined authority structure that determines who gets to tell others what they have to do to remain employed. Other groups have a different primary task: that of generating meaning for its members. One such group with which I have had the privilege of becoming acquainted is Alcoholics Anonymous (AA). According to AA’s Fifth Tradition, “Each AA group has but one primary purpose—to carry its message to the alcoholic who still suffers.” Note that the primary task is not to stop drinking. The boundaries 60 roth of AA are clearly described in the Third Tradition: “The only requirement for AA membership is a desire to stop drinking.” The premise of this idea is that we might learn from the experience of sober alcoholics how to become more effective members of our own professional society. While each of us earns an income from our professional work, and our society collects dues (taxes) to remain solvent, the American Group Psychotherapy Association (AGPA) does not have a primary task of generating income. I suggest that our primary task is to carry a message consistent with the ideals that led us to become mental health professionals and group psychotherapists: that mental illness is treatable ; that a knowledge base exists to provide that treatment; and that training in the acquisition of that knowledge is useful, if not essential, in the care of those who suffer. Some of our efforts may understandably be directed toward the community outside of our profession, including allied professions and the general public. What may be less appreciated is the importance of carrying a message to each other. As demand for our services has grown, and reimbursement patterns have shifted to rewarding seeing a larger numbers of patients for less time and less frequently, we may have less and less opportunity to develop ongoing, deep connections with our patients. While our training dictates that the needs of our patients are paramount, a decreasing quality of interaction with our patients may take a toll on us personally. We are certainly encouraged to maintain an active social context of relationships outside of our work, to provide us with such needs for personal attachment, but the nature of our work, which entails boundaries of confidentiality, may set up a barrier for us in connecting our professional and personal worlds. Here is precisely where I suggest that our professional society fills a need, as the middle ground between our professional practices and our social milieu. If we come together to support each other, by creating our own social network of...

Thirty years of National Chemistry Week

This fall, we will celebrate 30 years of National Chemistry Week (NCW). In 1987, when then-ACS Immediate Past President George Pimentel launched National Chemistry Day, only he appeared to imagine the lasting impact that the outreach event would have on the American Chemical Society and the greater chemistry community. During that first celebration, Pimentel led ACS members and staff in a parade down 16th Street in Washington, D.C., past the ACS headquarters building. By 1989, more than half of ACS’s local sections had expanded their celebrations to a week, and in 1993 National Chemistry Day was officially renamed National Chemistry Week. This year’s 30th anniversary theme of “Chemistry Rocks!” calls on NCW coordinators and ACS volunteers to bring the excitement of geochemistry to children and adults across the U.S. and the world the week of Oct. 22–28. NCW enables ACS members to participate in two of ACS’s four strategic goals:

“To Die for a Lousy Bike”: Bicycles, Race, and the Regulation of Public Space on the Streets of Washington, DC, 1963–2009

On August 11, 1972, District of Columbia police shot and killed Gregory Coleman, an African American teenager riding a bicycle that they had planted in front of a grocery store as part of a “bicycle stakeout” sting operation. At his memorial service a little over a week later, Gregory’s father, Lancelot Coleman, said, “The whole thing was senseless that my son had to die for a lousy bike.” Coleman’s death foreshadowed a half-century of escalating law-and-order policies established across the United States for which African American youths would experience the most severe of consequences. Bicycling was implicated in these trends. Officers used mandatory bicycle registration and bicycle stakeouts to patrol racial boundaries in a city where the majority of the population was African American. As a vehicle for physical mobility and a source of play for young people during an era of intense federal attention to juvenile delinquency, the bicycle became a fulcrum for efforts to maintain segregated public spaces in the District.

The US Great Recession: exploring its association with Black neighborhood rise, decline and recovery

ABSTRACTThe United States experienced the Great Recession between 2007 and 2009 and many American cities and communities are still suffering from its legacy. During the prior period of the early and mid-2000s, many inner city African American communities were experiencing gentrification, driven in part by the real estate bubble that popped in 2007. While much has been written about the institutional and structural causes and consequences of the Great Recession, this article seeks to better understand its community-level implications by investigating the relationship between lending and property value patterns in three gentrifying African American communities just before, during and after this economic calamity. In particular, we investigate Bronzeville in Chicago, Harlem in New York City and Shaw/U Street in Washington, DC. Evidence suggests the Great Recession differentially influenced the development trajectories of these urban neighborhoods. In Bronzeville severe and prolonged property decline resulted, while much less economic stagnation was experienced in Harlem and Shaw/U Street. The Great Recession did not have uniform implications for urban African American neighborhoods: distinct community and city contexts, in particular racial and class neighborhood transitions and citywide unemployment and housing market conditions, mediate the influence of national economic decline and recovery.

Estimation of Short-Term Bus Travel Time by Using Low-Resolution Automated Vehicle Location Data

Estimation of short-term bus travel time is an essential component of effective intelligent transportation systems (ITS), including traveler information systems and transit signal priority (TSP) strategies. Several technologies, such as automated vehicle location (AVL) systems, can provide real-time information for estimation of bus travel time. However, low resolution of data from such technologies presents a challenge to accurate estimation of travel time. Several models for estimation of bus travel time at signalized urban arterials were developed and tested. These models used low-frequency AVL data and required only knowledge of network specifications such as locations of bus stops and intersections. First, a linear regression model was developed; it decomposed total travel time into its components, including running travel time, dwell time at bus stops, and delay at signalized intersections. Second, various machine learning models, including support vector regression (SVR) with nonlinear kernel, ridge, Lasso, decision tree, and Bayesian ridge were trained by using Python libraries such as scikit-learn and evaluated. A segment of Washington Street in Boston, Massachusetts, was selected as the study site. The results indicate that the SVR model outperformed other regression models in generalized error measures, in particular those of mean absolute error and root mean square error. The findings of this study can lead to improved traveler information systems and more-efficient TSP strategies and, overall, can contribute to better transit quality of service.
