This book explores important aspects of Markov and hidden Markov processes and the applications of these ideas to various problems in computational biology. It starts from first principles, so that no previous knowledge of probability is necessary. However, the work is rigorous and mathematical, making it useful to engineers and mathematicians, even those not interested in biological applications. A range of exercises is provided, including drills to familiarize the reader with concepts and more advanced problems that require deep thinking about the theory. Biological applications are taken from post-genomic biology, especially genomics and proteomics. The topics examined include standard material such as the Perron–Frobenius theorem, transient and recurrent states, hitting probabilities and hitting times, maximum likelihood estimation, the Viterbi algorithm, and the Baum–Welch algorithm. The book contains discussions of extremely useful topics not usually seen at the basic level, such as ergodicity of Markov processes, Markov Chain Monte Carlo (MCMC), information theory, and large deviation theory for both i.i.d and Markov processes. It also presents state-of-the-art realization theory for hidden Markov models. Among biological applications, it offers an in-depth look at the BLAST (Basic Local Alignment Search Technique) algorithm, including a comprehensive explanation of the underlying theory. Other applications such as profile hidden Markov models are also explored.Less

Event modeling systems provide a semantic interpretation of sequences of pixels that are captured by a video camera. The design of a practical system has to take into account the following three main factors: low-level preprocessing limitations, computational and storage complexity of the event model, and user interaction. The hidden Markov model (HMM) and its variants have been widely used to model both speech and video signals. Computational efficiency of the Baum-Welch and the Viterbi algorithms has been a leading reason for the popularity of the HMM. Since the objective is to detect events in video sequences that are meaningful to humans, one might want to provide space in the design loop for a user who can specify events of interest. This chapter explores this using semantic approaches that not only use features extracted from raw video streams but also incorporate metadata and ontologies of activities. It presents three approaches for applications such as event recognition: anomaly detection, temporal segmentation, and ontology evaluation. The three approaches discussed are statistical methods based on HMMs, formal grammars, and ontologies. The effectiveness of these approaches is illustrated using video sequences captured both indoors and outdoors: the indoor UCF human action dataset, the TSA airport tarmac surveillance dataset, and the bank monitoring dataset.Less

This chapter considers the basic properties of hidden Markov processes (HMPs) or hidden Markov models (HMMs), a special type of stochastic process. It begins with a discussion of three distinct types of HMMs and shows that they are all equivalent from the standpoint of their expressive power or modeling ability: Type 1 hidden Markov model, or a HMM of the deterministic function of a Markov chain type; hidden Markov model of Type 2, or a HMM of the random function of a Markov chain type; and hidden Markov model of Type 3, or a HMM of the joint Markov process type. The chapter also examines various issues related to the computation of likelihoods in a HMM before concluding with an overview of the Viterbi algorithm and the Baum–Welch algorithm.Less

This chapter examines how Hugo Bettauer’s 1923 novel The City Without Jews explicitly addresses the way in which the presence of Jews in interwar Vienna was in fact conditional upon their accepting an abstract form of their own “absence.” By omitting Jewish women from the text, the book also reveals how Jewish men predicated the possibility of their own presence upon the effacement of Jewish women. The implications of this gendered absence are explored via examples from the publishing industry. Publishers provided opportunities for Jewish women to earn a living as writers, translators, and literary agents, but only at the price of strictly limiting their content. Vicki Baum was more successful in the German market, but the rigidity with which she was marketed as a New Woman by her Jewish publishers in Berlin indicates the strict limits placed upon her visibility in the public sphere. Ironically, those same limits allowed Austrian writers like Mela Hartwig to experiment with less mainstream writing styles and content, albeit at the cost of Jewish visibility. The lives of these writers underscore the various ways in which Austrian literature—and its accompanying rules of consumption—framed the condition of Jewish “absence.”Less

This new multiauthor volume will examine The Wizard of Oz and its surrounding culture, centering on three areas of study: early adaptations of Baum’s novels, insights into the MGM film, and the legacy of The Wizard of Oz on the popular stage. Although the articles will devote some attention to the genesis of the musical and the biographical profiles of the creative team, the book will prioritize critical and analytical readings. Authors will primarily illuminate the reasons why The Wizard of Oz has become iconic in the history of the movie musical, acknowledging the great lengths to which MGM went in making it an exceptional project, and why it continues to hold so much appeal in the twenty-first century. The development of the score will receive particularly close attention, filling an important gap in the literature and addressing the fact that the songs are key to the movie’s popularity. Two central chapters will address the music in the MGM film, considering the interaction between the songs and the underscore, and also reflecting on the enduring appeal of the musical numbers. But the significance of the music in early stage productions and later reinterpretations will also be given careful attention: several of the authors will question how the music is employed alongside other components—on stage and screen—and to what effect. Ultimately, the book will incorporate a variety of scholarly approaches, to present an authoritative and engaging understanding of one of the most significant movie musicals that will appeal to film lovers and academics alike.Less

This chapter discusses how a neophyte Hollywood filmmaker (Anthony Mann) directing a veteran Hollywood filmmaker (Erich von Stroheim) led to tensions during production on the low-budget film noir, The Great Flamarion. Given another cursory assignment from Republic Pictures, Mann was able to elevate the exaggerated melodramatic topic of a calculating young female (Mary Beth Hughes) ruining a gullible older man (Stroheim) to fascinating artistic and thematic levels. Although based on a short story by Austrian author Vicki Baum (Grand Hotel), virtually nothing of the original material remains aside from the central figure being a professional sharpshooter. While The Great Flamarion is not as famous as Fritz Lang’s Scarlet Street of the same year, the chapter suggests that the Mann picture may have had influences on the more expensive Lang film not only in the choice of subject matter (younger woman exploiting older man) but also in a climactic dialogue scene.Less

With a focus on the Amazon diaries of Roger Casement and the testimony of West Indian labourers in the Putumayo, this chapter examines literature from the Rubber Boom. In particular, it considers the intersection between fact and fiction in representations of extreme violence in this period, including in The Weeping Wood by the German Jewish émigré writer, Vicki Baum and El sueño del celta by Mario Vargas Llosa. The question of tropical degeneration, and the extent to which it was seen as responsible for the atrocities of the Rubber Boom, is discussed in the second half of the chapter. Less

This chapter addresses the early stage adaptations of several of Baum’s books. The first musical comedy in 1902–1903 generated huge excitement, and inspired Baum to continue with his second novel in 1904. The following two decades were full of interchange between novels, stage productions, and films, with each iteration fueling interest in the world of Oz and its fantastic characters. The chapter examines several of these productions, including basic information about their contributions, but the focus is on the relationship between the stars chosen for the roles and the talents (dancing, singing, comedy, drama) they brought to the version they starred in. For example, Montgomery and Stone, a comedy duo popular in vaudeville and on Broadway, were the stars of the first show. Thus, it was the Tin Woodman and the Scarecrow who were the focus. Other performers, such as Charles Ruggles and Charlotte Greenwood, were the main attractions to their specific productions, too. In the end, the most successful Oz productions found clever ways to allow star players to shine and showcase their talents while maintaining some element of the narrative. It is this formula that would, in part, lead directly to the powerful impact of the 1939 film musical.Less

Chapter 5 continues to unpack Congar’s theory of doctrinal development, but this time, highlighting the role that history plays. Consequently, Chapter 5 treats the third and fourth motors of doctrinal development: heresy and history. Examples are given of history’s influence on Church teaching and it is shown that history affects what the Church teaches, that that Church teaches it (at all), and why the Church teaches it this way (rather than another way). Examples are given of how history challenges the Church’s doctrinal tradition (e.g. Extra ecclesiam nulla salus), and how the world assists the Church’s doctrinal tradition (e.g. transubstantiation and philosophical-linguistic influences on doctrine). The second half of the chapter seeks to categorize Congar’s theory of doctrinal development. It compares Congar’s theory to those of other figures (e.g. Jossua, Baum, Journet). It is argued that Congar’s theory can be termed “episodic” but also “homogeneous.”Less
