Different Types

Written texts, especially sacred texts, can be handled in different ways. They can be read for semantic content; or they can be materially experienced, touched, or even be inhaled or drunk. I argue that literacy ideologies regulate social acceptability of specific semantic and somatic text practices. Drinking or fumigating the Qurʾan as a medical procedure is a highly contested literacy event in which two different ideologies are drawn upon simultaneously. I employ the linguistic model of codeswitching to highlight central aspects of this event: a more somatic ideology of literacy enables the link to medicine, while a more semantic ideology connects the practice to theological discourses on the sacredness of the Qurʾan as well as to the tradition of Prophetic medicine. Opposition to and ridicule of the practice, however, comes from representatives of an ideology of semantic purity, including some Islamic theologians and most Western scholars of Islam. Qurʾanic potions thus constitute an ideal point of entry for analyzing different types of literacy ideologies being followed in religious traditions.

The Impact

A laboratory river model for the study of self-purification inhibition in a stream containing toxic substances is presented. It enables an engineering - technological prediction of the impact of toxic substances or wastewaters on dissolved oxygen (DO) profile in an organically polluted river downstream from the point of entry of toxic effluent thus providing rapidly and inexpensively significant design information to an environmental scientist or engineer. The method was applied to the toxicity evaluation of wastewaters from electroplating industry. The effects of copper, cyanide (representing two significant constituents of this type of wastewaters) and wastewater from electroplating industry on the biodegradation of organic municipal pollution in receiving stream were evaluated experimentally.

This book is an ethnographic study of controversial sounds and noise control debates in Latin America’s most populous city. It discusses the politics of collective living by following several threads linking sound-making practices to governance issues. Rather than discussing sound within a self-enclosed “cultural” field, I examine it as a point of entry for analyzing the state. At the same time, rather than portraying the state as a self-enclosed “apparatus” with seemingly inexhaustible homogeneous power, I describe it as a collection of unstable (and often contradictory) sectors, personnel, strategies, discourses, documents, and agencies. My goal is to approach sound as an analytical category that allows us to access citizenship issues. As I show, environmental noise in São Paulo has been entangled in a wide range of debates, including public health, religious intolerance, crime control, urban planning, cultural rights, and economic growth. The book’s guiding question can be summarized as follows: how do sounds enter and leave the sphere of state control? I answer this question by examining a multifaceted process I define as “sound-politics.” The term refers to sounds as objects that are susceptible to state intervention through specific regulatory, disciplinary, and punishment mechanisms. Both “sound” and “politics” in “sound-politics” are nouns, with the hyphen serving as a bridge that expresses the instability that each concept inserts into the other.

Point Of Entry

Regional differences among industry clusters have long been a puzzle, especially when performance differences are significant. This chapter examines the case of venture capital investing, in which Silicon Valley differs from the rest of the world despite attempts to imitate its model. The point of entry in this chapter is the contract between venture capitalist and entrepreneur. Although such contracts have been analyzed in other research, this chapter argues that the psychological effects of different contract styles are of primary importance to innovative outcomes of entrepreneurial ventures. Thus, it argues that regulatory focus theory, which considers the psychological effects of contracting, is essential to understanding differences in practice and outcomes in venture capital clusters.

Reducing Recidivism

In 2016, San Francisco (SF) implemented the Law Enforcement Assisted Diversion (LEAD) program, a harm reduction–based pre-booking diversion system for people who violate drug laws and/or are engaged in sex work. LEAD is set apart from existing diversion programs, as it uses police as point of entry. Prior LEAD studies indicate some success in reducing recidivism and improving life outcomes. However, less is known about program implementation, including barriers and facilitators. Relying on policy documents, interviews, and focus groups, this study describes the LEAD SF’s development, operations, adaptations, and challenges. It also identifies the unique context of LEAD SF that led to implementation barriers and facilitators. Results show that SF experienced success in collaboration, relationship building, and client connections to services but experienced challenges in securing and maintaining police officer buy-in and keeping clear and open lines of communication regarding LEAD goals, objectives, policies, and procedures. This led to the termination of LEAD SF in 2020.

Abstract When one of two infecting lambda phage types in a replication-blocked cross is chi + and DNA packaging is divorced from the RecBCD-chi interaction, complementary chi-stimulated recombinants are recovered equally in mass lysates only if the chi + parent is in excess in the infecting parental mixture. Otherwise, the chi 0 recombinant is recovered in excess. This observation implies that, along with the chi 0 chromosome, two chi + parent chromosomes are involved in the formation of each chi + recombinant. The trimolecular nature of chi +-stimulated recombination is manifest in recombination between lambda and a plasmid. When lambda recombines with a plasmid via the RecBCD pathway, the resulting chromosome has an enhanced probability of undergoing lambda x lambda recombination in the interval into which the plasmid was incorporated. These two observations support a model in which DNA is degraded by Exo V from cos, the sequence that determines the end of packaged lambda DNA and acts as point of entry for RecBCD enzyme, to chi, the DNA sequence that stimulates the RecBCD enzyme to effect recombination. The model supposes that chi acts by ejecting the RecD subunit from the RecBCD enzyme with two consequences. (1) ExoV activity is blocked leaving a highly recombinagenic, frayed duplex end near chi, and (2) as the enzyme stripped of the RecD subunit travels beyond chi it is competent to catalyze reciprocal recombination.
