Connection Between the Debranning Time and the Kernel Hardness of Wheat
Authors: Szabó Balázs P.
Published: May 2018

Surface cleaning has an important role in the technology of milling of wheat considering food security. Wheat hardness has an effect on the milling process, it determines the properties, qualities and end use of flours. In the last decade new debranning methods have appeared, which are able to better remove the shell of wheat grains applying rubbing surfaces. In my thesis I examined how different levels of debranning affect hardness and content of ash in wheat types with different grain structure. Conclusion is with approximately 4% of shell removed the hardness of grain. Further removing of shell does not result in further changes though. Reduction of hard wheat’s general grain size with longer debranning process is larger compared to soft wheat’s.

Authors: Kovács Róbertné , Keszthelyi-Szabó Gábor
Published: May 2018

This paper presents the findings of an experimental investigation into the effects of irradiation power (PM), flow rate (FR), and treating number (NT) in anaerobic digestion of food industrial wastewater. A two-level factorial experiment has been used to accomplish the objective of the experimental study. The specific energy demand (SED) of microwave treatment was the response variable investigated. The experimental results indicate that the proposed mathematical models suggested could adequately describe the performance indicators within the limits of the factors that are being investigated.
Monsters in the Machine
Authors: Hantke Steffen
Published: May 2018

During the 1950s and early 1960s, the American film industry produced a distinct cycle of films situated on the boundary between horror and science fiction. Using the familiar imagery of science fiction, the vast majority of these films subscribed to the effects and aesthetics of horror film, anticipating the dystopian turn of many science fiction films to come. These films often evinced paranoia, unease, fear, shock, and disgust. Not only did these movies address technophobia and its psychological, social, and cultural corollaries, they also returned persistently to the military as a source of character, setting, and conflict. Commensurate with a state of perpetual mobilization, the US military comes across as an inescapable presence in American life. Regardless of their genre, this book argues that these films have long been understood as allegories of the Cold War. They register anxieties about two major issues of the time: atomic technologies, especially the testing and use of nuclear weapons, as well as communist aggression and/or subversion. Setting out to question, expand, and correct this critical argument, the book follows shifts and adjustments prompted by recent scholarly work into the technological, political, and social history of America in the 1950s. Based on this revised historical understanding, science fiction films appear in a new light as they reflect on the troubled memories of World War II, the emergence of the military-industrial complex, the postwar rewriting of the American landscape, and the relative insignificance of catastrophic nuclear war compared to America's involvement in postcolonial conflicts around the globe.
Military Stock Footage
Authors: Hantke Steffen
Published: May 2018

This chapter focuses on the recruitment of the audience into the “military metaphysics” that C. Wright Mills decries as a symptom of America's Cold War mentality. More specifically, it reads attempts at recruitment made by science fiction films of the period through the use of military stock footage. Pilfering the public domain for footage to be inserted into one's own film was a standard device of inexpensive filmmaking that found one of its most extreme expressions in Alfred E. Green's Invasion U.S.A. (1952). Generally dismissed as a hack job and mercilessly lampooned by Mystery Science Theater 3000, Invasion U.S.A. is a prime example of a politically engaged film using one of the common stylistic devices of 1950s low-budget filmmaking.
Hollywood’s Passing Contexts
Authors: Kelley N. Megan
Published: May 2018

This chapter explores how concepts about identity changed after World War II by focusing on cultural contexts which affected the ways that Hollywood films were produced and consumed. In particular, it considers the rise of psychology, cultural anthropology, and the culture of the Cold War. It discusses the idea that identities were malleable and how it coexisted with discourses about authenticity and “identity crisis.” It also shows how Hollywood reflected and promoted atomic and Cold War fears, identity anxiety, and the rise of psychoanalytic discourse. The chapter suggests that all the divergent ideological strands and cultural beliefs that characterized the postwar period, including Cold War fears of an “enemy within” and the proliferation of identity studies, had influenced Hollywood representations of racial, gender, sexual, and political identities on-screen as well as audience interpretations of those representations.
“Hiding in Plain Sight”
Authors: Kelley N. Megan
Published: May 2018

This chapter focuses on political passing, in which the specter of passing was utilized in Hollywood films produced in the context of the Cold War. Films about political passing called into question who was who and the nature of identity. The notion that somebody could pass politically mirrored fears about racial passing, complicated by postwar obsessions with Communism. The chapter examines how anti-Communist films such as My Son John and Woman on Pier 13 tackle the “enemy within” and portray Communists as caricatures, either gangster-like or hyperintellectual, thus making visible what was supposed to be an invisible threat. It also considers the way anti-Communism in Hollywood exploited anxieties that were linked to postwar ideas about identity.
“Both Body and Meaning Can Do a Cartwheel”1
Authors: Kelley N. Megan
Published: May 2018

This chapter examines the crisis of masculinity as represented in Hollywood and on film. Evolving representations of masculinity were framed by the psychoanalytic turn in Hollywood, the objectification and eroticization of male bodies, the dominance of method acting, and questions about the nature of identity. These images uncoupled the stable categories of gender and sexuality, giving rise to more nuanced and anxiety-ridden representations of masculinity. The chapter considers how postwar Hollywood films charted a perceived breakdown of secure gender categories and by implication, a breakdown of sexuality. It discusses how “crisis of masculinity” films produced ambiguous masculine ideals, epitomized by the postwar “sigh guys.” Films that explore the passing guises of masculinity, such as The Man in the Gray Flannel Suit, Rebel without a Cause, Vertigo, and Some Like It Hot, are analyzed.
Hollywood’s Postwar Feminine Masquerades
Authors: Kelley N. Megan
Published: May 2018

This chapter examines representations of women and issues of femininity and feminine performance with respect to anxieties about authenticity and passing. A number of Hollywood films featured masculine women who played with categories of masculinity, such as Calamity Jane, Johnny Guitar, Touch of Evil, and Sayonara. Other films, like Gentlemen Prefer Blondes, Peyton Place, and All about Eve, implied that women were performing femininity or raised the issue of “passing for normal.” The chapter considers how idealized, overly constructed gender representations in Hollywood films reinforced rather than negated the ambiguity of gender and how femininity itself was suggestively constructed as a passing performance. It explains how Hollywood's images of feminine masculinity lent credence to perceptions that gender categories were breaking down and how representations of ambiguous women in Hollywood films refused to focus on anxiety.
Conclusion
Authors: Kelley N. Megan
Published: May 2018

This concluding chapter summarizes the book's main themes relating to the many different ways that Hollywood films represented passing between 1947 and 1960, thus casting light on the contradictory discourses about identity that coexisted in postwar American culture. The book has shown how Hollywood embraced the psychoanalytic turn and how representations of passing related to discourse about authenticity and identity went beyond issues of race or racial indeterminacy. Aliens passing as humans, communists passing as Americans, men passing as women and vice versa, or homosexuals passing as heterosexuals were all raised as possible scenarios that sparked a decade of anxiety and fear. The book has brought to the fore broader cultural anxieties about the instability and fragility of categories of race, gender, class, and sexuality—all of which were epitomized by Langston Hughes in his 1952 short story collection Laughing to Keep from Crying.
“In the Darkest Zones”
Authors: McCort Jessica R.
Published: May 2018

This essay focuses specifically on the recent fairy-tale novels Coraline and A Tale Dark and Grimm as examples of gruesome, morally impactful modern fairy tales. Jessica R. McCort situates these particular books in relation to twentieth-century women authors’ dark fairy-tale revisions that emphasize identity development and the current cultural moment, a time in which mainstream American culture is obsessed with the darker side of fairy tales and the resurgence and rehabilitation of the fairy tale. Both Coraline and A Tale Dark and Grimm, filled with violence, gore, and horror, hearken back to the literary fairy tales that precede them and concentrate on the idea that children must learn to conquer their demons in order to achieve self-awareness. As McCort argues, these novels illustrate that children can gain, through textual encounters with the horrific, an enhanced sense of self and the power of bravery. In the end, this essay argues that these books are excellent examples of the social importance of maintaining terror as part of the texture of modern fairy tales for young readers, especially those in which the pursuit of personal identity is at the apple’s core.
Didactic Monstrosity and Postmodern Revisionism in Contemporary Children’s Films
Authors: Kunze Peter C.
Published: May 2018

Peter C. Kunze investigates films for children that engage elements of horror, concentrating on the intersection between postmodernism and children’s cinema. Closely examining two films in which the monstrous is a key aspect of the films’ aesthetic, Shrek and Monsters, Inc., Kunze examines the postmodern aspects of these films, considering their revisionary stance, their use of double address, and their allusive nature. As the essay progresses, he hones in on the narrative construction of the monster in these films and the processes by which they revise monstrosity. Kunze demonstrates, overall, that these films illustrate for the child viewer “the benefits of confronting the Other not to destroy it, but to appreciate it and work towards mutual understanding” and offers a useful methodology for thinking about the monster in children’s books and films targeted toward the young that have been produced during the new millennium.
Invisible Man and the Politics of Love
Authors: Butler Robert
Published: May 2018

Robert Butler’s “Invisible Man and the Politics of Love” rebuts the critique of Ellison as insufficiently engaged politically and alienated from authentic black culture, voiced most recently in Arnold Rampersad’s biography and Barbara Foley’s Wrestling with the Left: The Making of Ralph Ellison’s Invisible Man. Butler argues that this view of Ellison misreads the extent of Ellison’s authentic political commitment, which is far more rigorous and complex than Foley’s reductive treatment of his so-called flight from leftist extremism into “mythic individualism.” Butler explores what he calls Ellison’s commitment to Christian love and integration, bringing into relief a political vision that is far more harmonious with the Civil Rights activism of Martin Luther King than the outmoded Marxism that Ellison abandoned in the early 1940s. In Butler’s view, Ellison’s political concept of integration and mutual love is strongly attuned to the needs of America in the 21st century.
Father Abraham
Authors: Conner Marc C.
Published: May 2018

Marc Conner’s “Father Abraham: Ellison’s Agon with the Fathers in Three Days Before the Shooting . . .,” places Ellison’s essay “Tell It Like It Is, Baby” alongside Three Days to examine the role of fathers in Ellison’s writings. This brings into relief an array of father figures that challenged Ellison to confront his many absent fathers—biographical, historical, and literary—in the very process of writing the ongoing, unfinished second novel. One sees why Alonzo Hickman, the great father-figure within the novel, fails in rearing the child Bliss as a savior of his people, and why Bliss’s own flight from his community is doomed to fail, resulting in his fragmentation of identity and tragic loss of coherent self. Conner also argues against the simplistic relations between Ellison and Wright and Ellison and Faulkner and explores the far more complex signifying relations between Ellison and the work of Fitzgerald and Joyce.
Pan Rising: Women and the Steelband Movement
Authors: Munro Hope
Published: May 2018

This chapter examines the ways that women have contributed to the steelband movement in Trinidad and Tobago over the course of its history, and the roles that they are now playing as pannists, arrangers, and educators. On the surface, steel pan music seems to differ from calypso or soca in terms of performativity: as instrumental music, its conventions and practices are distinct from those of the genres of vocal music. However, the participation of women in the world of pan closely parallels their changing roles in various forms of expressive culture in Trinidad. The chapter considers the steelband movement's dramatic transformations reminiscent of those of calypso and Carnival during the 1940s and 1950s, including the rise of the Trinidad All-Steel Percussion Orchestra (TASPO) and the middle-class involvement with the movement.
This Woman's Work
Authors: Harwell Osizwe Raena Jamila
Published: May 2018

This Woman’s Work: The Writing and Activism of Bebe Moore Campbell is a social history and critical biography based on the life of award-winning writer Bebe Moore Campbell. This manuscript examines Bebe Moore Campbell’s life and activism in two periods: first, as a student at the University of Pittsburgh during the 1960s Black Student Movement; and second, as a mental health advocate near the end of her life in 2006. Primarily known as a bestselling novelist, Campbell’s first and final novels, Your Blues Ain’t Like Mine (1992) and 72 Hour Hold (2005) reveal a direct relationship to her lesser-known activist work. As a writer and activist, Bebe Moore Campbell used frame shifting within each of her works. Her writing thus becomes a powerful vehicle through which subject matter is enlivened and expanded, immersing her readers in relevant historical and sociopolitical phenomena. As a novelist, Bebe Moore Campbell utilized recurring signature themes within each novel to theorize and to connect popular audiences with African American historical memory and current sociopolitical issues. Similarly, Campbell’s bridge leadership, charismatic personality, and writing merge within two social movement organizations as she aids in significant grassroots/local and institutional change.
Medievalist Comics and the American Century
Authors: Bishop Chris
Published: May 2018

The comic book has become an essential icon of the “American Century,” an era defined by optimism in the face of change and by the recognition of the intrinsic value of democracy and modernization. For many, the Middle Ages stand as an antithesis to these ideals, and yet medievalist comics have emerged, endured, even thrived alongside their superhero counterparts.
Hal Foster’s Prince Valiant emerged from an America at odds with monarchy but still in love with King Arthur. Green Arrow is the continuation of a long fascination with Robin Hood that has become as central to the American identity as it has to the British. The Mighty Thor reflects the legacy of Germanic migration into the United States. The rugged individualism of Conan the Barbarian owes more to the western cowboy than it does to the continental knight-errant, and in the narrative of Red Sonja we can trace a parallel history of Feminism.
This study began as a Kluge Fellowship at the Library of Congress (the worlds’ largest repository of comic books). It offers a reception history of medievalist comics, contextualizing them against a greater backdrop of modern American history. It illuminates some of the ways in which we use our imagined past to navigate the present, and it plots some possible futures as we transition into the “Asian Century.”
The Green Arrow (1941)
Authors: Bishop Chris
Published: May 2018

The stories of Robin Hood constitute the collective memory of popular counter-culture. The chapter entitled “Green Arrow” posits the legends of the green wood as the antecedent for this successful comic book series, but any look at Robin Hood leads also to the contested medievalisms of James Macpherson and Thomas Percy, the relationship of these men with Samuel Johnson, and the democratization of their vision through the work of the American scholar Francis James Child. Child, in turn, brings into our gaze the Boston Brahmin Charles Eliot Norton and, through him, the poet Henry Wadsworth Longfellow before we return once again to Howard Pyle whose singular vision, perhaps more than any other person, has shaped so much of how the 20th century sees the Middle Ages.

Community periodontal index of treatment needs and pain control beliefs in relation to calcium-phosphate parameters and iron metabolism among hemodialysis patients
Authors: Książek Katarzyna , Żołnierz Joanna , Sak Jarosław Jerzy
Published: May 2018

Introduction. According to scientific reports, lack of oral hygiene, as well as disturbances in the calcium-phosphate and iron metabolism disorders are the main causes of periodontitis. The analysis of factors influencing the development and treatment of periodontitis should be conducted parallel in the medical and psychological domain.

Aim. The aim of this study was to determine the dependency between the community periodontal index of treatment needs (CPITN) and the beliefs about pain control and biochemical parameters of the iron, calcium and phosphate metabolism.

Material and methods. The study was conducted on a group of 124 hemodialysis patients with chronic renal failure aged from 24 to 90 (M=65.47; SD=15.65). The urea reduction rate (URR) was 71.24% and an average dose of dialysis (Kt/V) was 1.35. In the research time the indicators such as the values of serum levels of calcium and phosphorus, transferrin, ferritin, and iron were under control. Patients were diagnosed using the periodontal index of treatment needs (CPITN) and beliefs about pain control questionnaire (BPCQ) in Polish adaptation done by Z. Juczyński. In order to evaluate intergroup differences, the Kruskal-Wallis H test was used.

Results. The hemodialysis patients with stage 2 or stage 3 periodontitis (according to CPITN) had the highest levels of transferrin and the lowest levels of ferritin (Table 3.). In contrast, the patients with stage 4 CPITN had the lowest level of transferrin and the highest level of ferritin. No statistically significant differences were observed between the five stages according to the community periodontal index of treatment needs (CPITN) in relation to the three domains of the beliefs about pain control questionnaire (BPCQ).

Conclusions. The hemodialyzed patients with the most advanced periodontitis (stage 4 according to CPITN) had the lowest transferrin serum levels and the highest ferritin serum levels. They did not differ in pain control beliefs associated with the community periodontal index of treatment needs (CPITN).

Introduction. The organizational structure of the National Emergency Medical system ensures the health of citizens. Unfortunately, patients present dangerous behaviors, thereby damaging the safety of workers during medical emergencies. Aggression and violence, in spite of the widespread perception of it as a negative phenomenon undermining the individual’s health, is an indispensable part of everyday life and work environment.

Aim. The purpose of this study was to determine the incidence of acts of aggression that led to violence, and the types of occurrence of this phenomenon, which influenced the staff of the National Emergency Medical system.

Material and methods. The study was conducted in 2015/2016 among the employees of the National Emergency Medical system in Lublin, Puławy and Zamość; the research tool was a questionnaire survey.

Results. On the basis of the conducted research, it can be concluded that the employees of the National Emergency Medical system are, to a large extent, exposed to acts of aggression on the part of patients. Almost all the employees of the Accident & Emergency Units (98.2%) and almost all the employees of the Medical Rescue Teams (98.3%) encountered aggression from the patients.

Conclusion. There observed a phenomenon of aggression as well as verbal and physical violence on the part of patients towards health care workers. Alcohol and drugs increased both verbal and physical aggression among patients.

Employees of the National Emergency Medical system have indicated aggression as an intrinsic element in the work environment.

Conclusions. This study demonstrated good quality of health care in the examined hospital in Lublin. However, it is important to emphasize the need for further research aimed at collecting data on the presented problem.
Modern gastronomic technologies in optimization of pro-health food potential
Authors: Szponar Bogdan , Marzec Agnieszka , Skrzypek Michał
Published: May 2018

All human senses participate in the sensory evaluation of food, which means that such features as taste, flavour, appearance, or texture determine the acceptance and choice of a dish. Seeking to satisfy consumer requirements and offer a dish or food with the desired organoleptic features, the food industry initially used a wide range of food additives compensating for the loss of colour, taste or flavour of the dish. At present, with an increase in consumers’ awareness and nutrition knowledge, departure is observed from the use of food additives to the benefit of using modern technologies in the food industry. The progress in food science, concerning especially, the phenomena taking place during the storage or processing of food, gives direction to the application of modern technical solutions or materials, and also provides guidelines within the area of gastronomic technology concerning the shaping of not only organoleptic features of the dish, but also activities aiming at the preservation of pro-health potential of food. This issue becomes even more important in the context of increasing epidemics of chronic non-communicable diseases (NCD) in contemporary western societies, in the etiopathogenesis of which, health behaviours play a crucial role. The subject of the report will be analysis of the current state of knowledge in the area of food and nutrition sciences, concerning the possibility of using modern gastronomic technologies in order to preserve or enhance the pro-health potential of food, possible to use within the primary and secondary prevention of NCD.
Population ageing and inter-generational relations in the MENA: what role for social policy?
Authors: Messkoub Mahmood
Published: May 2018

Declining fertility and rising life expectancy combined with migration are changing the demographic landscape of the MENA. Earlier high fertility will ensure a growing population in the next 20-30 years. Family structure is also changing: families are becoming smaller and increasingly nuclear, rather than extended. The region has to manage a young age structure and a gradual ageing of the population but with a potential weakening of the traditional inter-generational support based on family, it also faces a widely varying and heterogeneous resource base and socio-economic structure across the different countries. To maintain and improve inter-generational support within family and society in the MENA countries with large populations (such as Iran and Egypt) the most important challenges are poverty and vulnerability, unemployment, and development of long-term plans for an ageing population. These are inter-connected objectives since reducing poverty and increasing current employment could provide individuals and families with some resources to save and accumulate for old age. States in the region should put redistributive social policies in the areas of health, education and housing at the heart of a strategy of supporting family budgets and resources to assist them in their inter-generational care, but should also set up care and pension schemes to provide societal intergenerational support.

Published: May 2018

Elderly patients with end stage kidney disease represent a challenge for surgeons to create a vascular access.

Determine predictive parameters functionality of the arteriovenous fistulas for hemodialysis in the elderly.

The study was organized as a retrospective study at the Center for Dialysis, Clinic for Urology and Nephrology, Clinical Center Kragujevac. The study included patients older than 65 years with arteriovenous fistula thrombosis, in the period of four years, in which there is information on the length of the functioning fistula. The study included 48 patients, mean age 71.3±5.2 years, 29 (60%) men and 19 (40%) women. The data were analyzed according to gender and demographic structure, type of anastomosis, positioning, length of functioning fistulas, and the lumen diameter of the arteries and veins that are used to create a fistula.

The median length of functioning arteriovenous fistula, based on Kaplan-Meier model, is 16 months (95% CI 6.9-25.1). Median functioning for proximaly located fistulas was 24 months (range, 1-259), while median functioning in patient with distally located fistulas was 8 months (range, 1-96). The difference in relation to the positioning of the fistula was statistically significant (p=0.006). In univariate Cox regression model, a statistically significant predictor of the functioning of arteriovenous fistulae is fistula positioning (B=0.700; p=0.022).

The predictive parameter of survival of arteriovenous fistulas in elderly is proximally located fistula.

Risberg, MA, Steffen, K, Nilstad, A, Myklebust, G, Kristianslund, E, Moltubakk, MM, and Krosshaug, T. Normative quadriceps and hamstring muscle strength values for female, healthy, elite handball and football players. J Strength Cond Res 32(8): 2314–2323, 2018—This study presents normative values for isokinetic knee extension and flexion muscle strength tests in 350 elite, female, handball (n = 150) and football (n = 200) players. Isokinetic concentric muscle strength tests at 60°·sec−1 were recorded bilaterally using a dynamometer. Peak torque (in Newton meter [N·m]), body mass normalized peak torque (N·m·kg−1), and hamstring to quadriceps ratio (H:Q ratio) for dominant and nondominant legs were recorded. The female elite players were 20.9 ± 4.0 years, started playing at the elite level at the age of 18.2 ± 2.7 years, with a mean of 9.7 ± 2.2 hours of weekly in-season training. Handball players demonstrated greater quadriceps muscle strength compared with football players (11.0%) (p < 0.001), also when normalized to body mass (4.1%) (p = 0.012), but not for weight-adjusted hamstring muscle strength. The H:Q ratio was higher on the dominant compared with the nondominant leg for handball players only (p = 0.012).The H:Q ratio was significantly lower for handball players (0.58) compared with football players (0.60) (p < 0.02). These normative values for isokinetic knee extension and flexion torques of healthy, elite, female handball and football players can be used to set rehabilitation goals for muscle strength after injury and enable comparison with uninjured legs. Significantly greater quadriceps muscle strength was found for handball players compared with football players, also when normalized to body mass.

Estimating the Parameters of Kumaraswamy Distribution Using Progressively Censored Data
Authors: EL-Sagheer Rashad M.
Published: May 2018

In this paper, the maximum likelihood, Bayes, and parametric bootstrap methods are used for estimating the unknown parameters, as well as some lifetime parameters reliability and hazard functions, based on progressively Type II right-censored samples from a two-parameter Kumaraswamy distribution. Approximate confidence intervals (ACIs) for the unknown parameters, as well as reliability and hazard functions, are constructed based on the s-normal approximation to the asymptotic distribution of maximum likelihood estimators (MLEs) and log-transformed MLEs. In addition, two bootstrap CIs are also proposed. The classical Bayes estimates cannot be obtained in explicit form, so we propose to apply the Markov chain Monte Carlo (MCMC) technique to tackle this problem, which allows us to construct the credible interval of the involved parameters. Gibbs within the Metropolis–Hasting sampling procedure has been applied to generate MCMC samples from the posterior density function. Based on the generated samples, the Bayes estimates and highest posterior density credible intervals of the unknown parameters, as well as reliability and hazard functions, have been computed. The results of the Bayes method are obtained under both the balanced squared error (BSE) loss and balanced linear-exponential (BLINEX) loss. A real-life data set is analyzed to illustrate the proposed methods of estimation. Finally, a Monte Carlo simulation study is carried out to investigate the precision of the Bayes estimates with MLEs and two bootstrap estimates, also to compare the performance of different corresponding CIs considered.
An Experimental Study on the Effects of Adding Steel and Polypropylene Fibers to Concrete on Its Resistance after Different Temperatures
Authors: Pachideh Ghasem , Gholhaki Majid
Published: May 2018

The use of fibers in concrete improves strength, ductility, and durability of concrete. Concrete has fireproofing properties, but rebars are the most important concern of reinforced concrete structures in the event of a fire outbreak. Therefore, one of the recommendations to reduce these risks is the use of alternative materials like fibers. In this article, the effects of different temperatures on the mechanical properties of concretes with different cement contents containing steel and polypropylene fibers were studied. The specimens were placed under temperatures of 25°C, 100°C, 250°C, 500°C, and 700°C, and the results revealed that the effects of fire on concrete containing steel fibers are more damaging. Also, the compressive strength and modulus of rupture at 25°C and tensile strength at 250°C have the maximum values. Compressive and tensile strengths of concrete containing steel fibers were 40 % and 50 %, respectively, more than the concrete containing polypropylene fibers. However, their flexural strength was almost equal. By comparing the flexural strength of specimens with grade 400 and grade 700, it can be concluded that the specimens with grade 400 have more resistance by about 10 to 40 %.
Coastal Sage
Authors: Osborne Thomas J.
Published: May 2018

There are moments when we forget how fortunate we are to have the California coast. The state is home to 1,100 miles of uninterrupted coastline defined by long stretches of beach and jagged rocky cliffs. Coastal Sage chronicles the career and accomplishments of Peter Douglas, the longest-serving executive director of the California Coastal Commission. For nearly three decades, Douglas fought to keep the California coast public, prevent overdevelopment, and safeguard habitat. In doing so, Douglas emerged as a leading figure in the contemporary American environmental movement and influenced public conservation efforts across the country. He coauthored California’s foundational laws pertaining to shoreline management and conservation: Proposition 20 and the California Coastal Act. Many of the political battles to save the coast from overdevelopment and secure public access are revealed for the first time in this study of the leader who was at once a visionary, warrior, and coastal sage.
Charles Burnett
Authors: Naremore James
Published: May 2018

In this, the first book devoted to one of the world’s most admired independent filmmakers, James Naremore offers a close critical study of all of Charles Burnett’s important works for movies and television—among them Killer of Sheep, My Brother’s Wedding, To Sleep with Anger, The Glass Shield, Nightjohn, The Wedding, Nat Turner: A Troublesome Property, and Warming by the Devil’s Fire. Naremore shows that Burnett’s important career has developed against the odds and that his artistry, social criticism, humor, and commitment to “symbolic knowledge” have given his films enduring value.
Food and Power
Authors: Avieli Nir
Published: May 2018

Drawing on ethnography conducted in Israel since the late 1990s, this book considers how power is produced, reproduced, negotiated, and subverted in the contemporary Israeli culinary sphere. The book explores issues such as the definition of Israeli cuisine (a defining element of which is large portions of “satisfying” dishes made from mediocre ingredients), the ownership of hummus, Israel's Independence Day barbecues, the popularity of Italian food in Israel, the privatization of communal Kibbutz dining rooms, and food at a military prison for Palestinian detainees to show how cooking and eating create ambivalence concerning questions of strength and weakness and how power and victimization are mixed into a sense of self-justification that maintains internal cohesion among Israeli Jews. The book concludes by presenting two culinary trends in contemporary Israel that emerge at the intersection of food and power.
Introduction
Authors: Tamari Salim
Published: May 2018

This introductory chapter discusses the significance of the remaking of Palestine as an autonomous geographic entity within greater Syria and the Ottoman Arab provinces. During the eighteenth and nineteenth centuries, Filistin was not a separate administrative unit within the Ottoman sultanate, but the term Filistin was designated for a region embedded in the provinces of Bilad al-Sham (Syria). It was frequently used to indicate the southern region of Syria, corresponding to the combined sanjaqs (districts) of Akka, Nablus, and Jerusalem. In this regard, the chapter states that the importance of Rafiq al-Tamimi's work is that it provided unique ethnographic distinctions to each of those districts, with detailed and sharp field observations about the customs, mores, and cultural practices of southern Syria as a whole.
Crime of Nationalism
Authors: Kelly Matthew Kraig
Published: May 2018

The Palestinian national movement gestated in the early decades of the twentieth century, but it was born in the Great Revolt of 1936–39, a period of sustained Arab protest against British policy in Palestine. In this book, Matthew Kraig Kelly makes the novel case that the key to understanding the rebellion lies in the "crimino-national" domain—a hitherto neglected area of overlap between criminological and nationalist discourses, and the primary terrain upon which the war of 1936–39 was fought. As Kelly elaborates, apart from national autonomy, the Palestinian rebels’ primary objective was to repudiate the British framing of their national movement as a criminal enterprise. The rebels therefore appropriated the institutions and even the aesthetics that betokened London’s legal title to Palestine, donning rank-specific uniforms and erecting their own postal, prison, and justice systems. In thus establishing the rudiments of a state, Palestinians shifted the criminal mantle onto their opponents: the British and the Zionists. Crime, in this sense, was the central preoccupation of the Palestinian national project, as it likely was of other such projects on the fringe of empire. Kelly's analysis amounts to a new history of the rebellion, and it offers important lessons for studies of interwar nationalism and insurgency more broadly.
Making of a Teenage Service Class
Authors: Ray Ranita
Published: May 2018

Stereotypes of economically marginalized black and brown youth focus on drugs, gangs, violence, and teen pregnancy. Common wisdom posits that targeting these “risk behaviors” is key to breaking the cycle of poverty. Ranita Ray uncovers the pernicious consequences of centering risk behaviors as key to targeting poverty. Ray spent three years among sixteen black and Latina/o youth from one economically marginalized neighborhood in a northeastern U.S. city, and she shares both harrowing and heartwarming accounts of their transition to adulthood as they try to obtain upward social mobility. The young people Ray came to know were invested in education, worked legal jobs, and denounced risk behaviors. She weaves tales of their family lives with the joys and heartbreaks of romance, intersecting it with their everyday battles with hunger, untreated illness, and the threat of eviction. We witness the young people take long bus rides to college and struggle to access computers and the Internet to complete homework. We see them exhausted from working multiple jobs as they try to balance work with school. The riveting accounts of the daily lives of youth that Ray presents do not fit into flashy headlines of drugs, gangs, and violence. Instead, she compellingly demonstrates how the disproportionate emphasis on risk behaviors reinforces class, race, and gender hierarchies, diverts important resources that could be focused on supporting the basic necessities and educational and occupational goals of marginalized youth, and ignores how educational inequalities function to channel ambitious and hardworking black and brown youth into the low-wage service class.
Chocolate Cities
Authors: Hunter Marcus Anthony , Robinson Zandria
Published: May 2018

Chocolate Cities is built on a simple premise: our current maps of black life are wrong. As Malcolm X made clear in Detroit over a half century ago, the geography of the black American experience is best understood as existing within and across varying versions of “the South”—regional areas with distinct yet overlapping and similar patterns of racism, white domination, and oppression alongside place-inspired black strivings, customs, and aspirations for a better and more equal society. Chocolate Cities offers a new geography of the United States based on the lives, experiences, and histories of black Americans called “the Black Map.” Using both cultural sources (film, music, fiction, and plays) and more traditional academic data—U.S. decennial census data (1900–2010); oral histories; multiyear ethnography; photographs; national, state, and local health and wealth data and reports; and archives—this book maps and analyzes black life since Emancipation in America’s “chocolate cities”—cities, towns, neighborhoods, streets, and communities wherein black life and culture are concentrated, maintained, created, and defended.
Barbed-Wire Imperialism
Authors: Forth Aidan
Published: May 2018

Some of the world’s first refugee camps and concentration camps appeared in the British Empire in the late 19th century. Famine camps detained emaciated refugees and billeted relief applicants on public works projects; plague camps segregated populations suspected of harboring disease and accommodated those evacuated from unsanitary locales; concentration camps during the Anglo-Boer War, meanwhile, adapted a technology of colonial welfare in the context of war. Wartime camps in South Africa were simultaneously instruments of military violence and humanitarian care. While providing food and shelter to destitute refugees and disciplining and reforming a population cast as uncivilized and unhygienic, British officials in South Africa applied a developing set of imperial attitudes and approaches that also governed the development of plague and famine camps in India. More than the outcomes of military counterinsurgency, Boer War camps were registers of cultural discourses about civilization, class, gender, racial purity and sanitary pollution. Although British spokesmen regarded camps as hygienic enclaves, epidemic diseases decimated inmate populations creating a damaging political scandal. In order to curb mortality and introduce order, the British government mobilized a wide variety of disciplinary and sanitary lessons assembled at Indian plague and famine camps and at other kindred institutions like metropolitan workhouses. Authorities imported officials from India with experience managing plague and famine camps to systematize and rationalize South Africa’s wartime concentration camps. Ultimately, improvements to inmates’ health and well-being served to legitimize camps as technologies of liberal empire and biopolitical security.
