THE problem of the expansion of a compressible fluid with friction and heat flow is one of great complexity. In this treatment it has been simplified to a one‐dimensional problem and the resulting relationships are thermodynamic. An expansion of this type cannot be described as reversible due to the presence of friction, and from this aspect the analysis may be suspect. However, any practical process is irreversible and it is common practice to apply to such processes an analysis which is theoretically confined to changes which occur reversibly. Thus, although the degree of irreversibility may be greater than usual in this case, there are many precedents for allowing the use of reversible thermodynamics in the analysis of irreversible changes. The relations for the expansion are well known, but the writer believes the analysis and discussion on the choking conditions of a nozzle are more general than anything yet published.

Addresses the standardization of the measurements and the labels for concepts commonly used in the study of work organizations. As a reference handbook and research tool, seeks to improve measurement in the study of work organizations and to facilitate the teaching of introductory courses in this subject. Focuses solely on work organizations, that is, social systems in which members work for money. Defines measurement and distinguishes four levels: nominal, ordinal, interval and ratio. Selects specific measures on the basis of quality, diversity, simplicity and availability and evaluates each measure for its validity and reliability. Employs a set of 38 concepts ‐ ranging from “absenteeism” to “turnover” as the handbook’s frame of reference. Concludes by reviewing organizational measurement over the past 30 years and recommending future measurement reseach.

In the wake of numerous late twentieth century cult disasters, and most recently, the September 11 tragedy, this paper considers the question, why do people obey outrageous commands from charismatic authorities? According to Gary Becker, “the economic ap‐proach provides a valuable unified framework for understanding all human behavior” (Becker 1976:14). We test this generalization by attempting to explain, in terms of rational choice theory, the behavior of two members of infamous cults, the Manson Family and the Ragneesh Foundation International. Each of these subjects slavishly obeyed orders from a charismatic personality, one to the extent of committing murder. Were they mentally ill or rationally maximizing their utility? We consider these theoretical options. In August of 1969 Charles Manson ordered several of his followers to commit gruesome murders for the purpose of initiating the apocalypse. They obeyed. In late 1978, Jim Jones commanded over 900 members of the Peoples Temple to commit suicide. They obeyed. From 1981 to 1985, executing orders to build utopia perceived to come from their guru, members of the Ragneesh Foundation International terrorized the inhabitants of Antelope, Oregon. Similarly, followers of Osama Bin Laden are suspected of carrying out the disastrous suicide murders of September 11. Over past decades, the incidence of violence involving submission to a charismatic leader appears to be escalating. Increasingly the public must contend with the “awesome power” of charisma, “enshrouded in a mystique of irrationality” (Bradley 1987: 3–4). The extent to which followers committing criminal acts of obedience may be held accountable has become a pressing legal issue. How can this kind of volatile religious commitment be explained? In recent years, experts on cults have experimented with rational choice theory. According to economist, Gary Becker, “the economic approach provides a valuable unified framework for understanding all human behavior” (Becker 1976: 14). We test this extravagant claim with two cases of seemingly irrational commitment to a charismatic cult leader—one a follower of Bhagwan Rajneesh, the other a Manson Family killer. These subjects are not representative cult members but rather were chosen because they demonstrated an exceptional loyalty to their leaders that has been widely construed as the result of brainwashing or insanity. Rather than survey data, we rely on autobiographical testimonies since they offer a more detailed and comprehensive view of the thought processes that motivate behavior, the subject matter of this paper.

It has often been said that a great part of the strength of Aslib lies in the fact that it brings together those whose experience has been gained in many widely differing fields but who have a common interest in the means by which information may be collected and disseminated to the greatest advantage. Lists of its members have, therefore, a more than ordinary value since they present, in miniature, a cross‐section of institutions and individuals who share this special interest.

The management of children′s literature is a search for value and suitability. Effective policies in library and educational work are based firmly on knowledge of materials, and on the bibliographical and critical frame within which the materials appear and might best be selected. Boundaries, like those between quality and popular books, and between children′s and adult materials, present important challenges for selection, and implicit in this process are professional acumen and judgement. Yet also there are attitudes and systems of values, which can powerfully influence selection on grounds of morality and good taste. To guard against undue subjectivity, the knowledge frame should acknowledge the relevance of social and experiential context for all reading materials, how readers think as well as how they read, and what explicit and implicit agendas the authors have. The good professional takes all these factors on board.

Du Bois's interest in the Japanese empire points us in the direction of examining non-Western imperial policies and discourses and how they relate to racialization. For Du Bois, Japan was an exemplar of a nonwhite empire. This chapter reconstructs a Du Boisian conception of race that identifies it closely with ethnicity, against the belief that the African-American intellectual held on to a merely biological conception of race. I argue that his thought evolved towards a social-construction approach in which race must be understood historically and in particular global contexts. By analyzing Japan's policies and discourses around the boundaries of the Japanese, I explicate how Japan carried out a process of self-racialization owing to its dialectical relationship with the West. It also racialized its colonial subjects in a process of in-group delineation according to Japan's imperial imperatives. The case of the Japanese empire demonstrates how a global/transnational approach to racialization is valuable. It also evinces how white supremacy and universalism are not the only logics of imperialism. Moreover, it shows that Du Bois believed white supremacy could be transcended. However, Du Bois was too idealistic about Japan's empire, ignoring how oppressive nonwhite imperial rulers can be toward their subjects even when there are phenotypical similarities between them.
