The purpose of this study is to quantify the relationship between the fluid flow and pressure drop for perforated plates. The homogenization of non-uniform fluid flows is often accomplished by passing the fluid through perforated plates. The underlying principle for the accomplishment of flow homogenization is a tradeoff of pressure drop for flow uniformity.

The investigation, implemented by numerical simulation, is based on turbulent flow in pipes and across perforated plates. The approach is as follows: (a) to devise a model to determine pressure drop’s fluid flow information from a single-aperture, (b) to obtain this information for apertures of different shapes, (c) to determine this type of information for perforated plates situated in a circular pipe, (d) to compare the entire perforated-plate pressure drop with that for a single-aperture modular and (e) to analyze two identical perforated plates in series.

The pressure drop results for the single-aperture modular model agreed very well with those for a whole perforated plate in a round pipe, therefore negating the need to simulate the more complex situation. In addition to the parametric study with aperture shape and Reynolds number, porosities (20-60 per cent) and plate thicknesses were also varied. The results obtained here compared favorably with experimental data.

This work demonstrates an efficient method for analyzing and obtaining useful pressure drop information for perforated plates. For the first time, the porous media approach for modeling perforated plates is compared directly to complete, full-scale perforated plate applications and identical plates in series.

The author sets out to achieve a better measurement of interorganisational power in distribution channels.

I examine patterns of making or deferring strategic repatriations that firms can use to either meet analysts' forecasts or defer to maintain future reported earnings flexibility. First, I examine the extent to which firms repatriate earnings from high foreign tax subsidiaries to decrease US tax expense, resulting in increased net income and lower cash taxes. Using federal tax return information, I find evidence that firms strategically repatriate these earnings to meet or beat current analysts' forecasts. Next, I find evidence that firms that are able to obtain current year tax reductions defer these repatriations in an attempt to build cookie-jar reserves. Lastly, I find that firms do not disclose high foreign tax repatriations (HTRs), even when required by SEC rules. This study contributes to the earnings management, tax avoidance, and disclosure literature by examining a discretionary tax planning strategy.

Prior to the passage of the 20th amendment to the US Constitution in 1920, several states had extended the suffrage to women. Helen Laura Sumner (later Woodbury), a student of John R. Commons at Wisconsin, undertook a statistical study of the political, economic, and social impacts of the granting of voting rights to women in the state of Colorado, and subsequently defended the results against numerous attacks. In this paper, we present a brief account of the struggle for women’s equality in the extension of the suffrage and examine Sumner’s critical analysis of the evidence as to its effects, as well as the counterarguments to which she responded.

Participative budgeting is one of the most intensively researched budgeting variables in management accounting. Research has stalled, however. The purpose of this paper is to stimulate further research by providing an overview of antecedents of participative budgeting and suggesting ways to build upon extant research.

We assess 22 studies published prior to 2011 that offer statistical insights into why organizations use participative budgeting by theorizing and modeling it as a dependent variable.

This work answers two research questions regarding why organizations use participative budgeting: (a) Which antecedents of participative budgeting have been analyzed so far? (b) Which causal-model forms are used in extant research regarding the antecedents of participative budgeting?

This paper provides a detailed overview of empirical studies and respective findings aiming to explain why organizations use participative budgeting. Many prior studies have measured the association between contextual antecedents and participative budgeting. However, from a theoretical perspective, objectives of employees and supervisors are often used to explain the relation. Based on our literature review, we propose that all objectives identified so far intervene in the relationship between context and use of participative budgeting and also further detail these objectives. Consequently, our review analyzes the status quo of research on why organizations use participative budgeting and adds additional suggestions of underlying causal processes that can be tested in future studies.

Purpose – This chapter offers an integrative review of psychological and neurobiological differences between younger and older adults that might impact economic behavior. Focusing on key health economic challenges facing the elderly, it offers perspectives on how these psychological and neurobiological factors may influence decision-making over the life course and considers future interdisciplinary research directions.

Methodology/approach – We review relevant literature from three domains that are essential for developing a comprehensive science of decision-making and economic behavior in aging (psychology, neuroscience, and economics), consider implications for prescription drug coverage and long-term care (LTC) insurance, and highlight future research directions.

Findings – Older adults face many complex economic decisions that directly affect their health and well-being, including LTC insurance, prescription drug plans, and end of life care. Economic research suggests that many older Americans are not making cost-effective and economically rational decisions. While economic models provide insight into some of the financial incentives associated with these decisions, they typically do not consider the roles of cognition and affect in decision-making. Research has established that older age is associated with predictable declines in many cognitive functions and evidence is accumulating that distinct social motives and affect-processing profiles emerge in older age. It is unknown how these age differences impact the economic behaviors of older people and implies opportunities for path-breaking interdisciplinary research.

Originality/value of the chapter – Our chapter looks to develop interdisciplinary research to better understand the causes and consequences of age-related changes in economic decision-making and guide interventions to improve public programs and overall social welfare.

A classification scheme by its notation does not do more than locate the subject; therefore, after the books are classified according to the scheme adopted, a secondary arrangement must be provided for the shelves, whereby books in a given class may be arranged in some order to accelerate finding and to differentiate one book from another. There are several methods in vogue of so arranging books in a given class, but one's choice will be, to some extent, determined by the System of issue in use. The usual methods are by:—

The following classified, annotated list of titles is intended to provide reference librarians with a current checklist of new reference books, and is designed to supplement the RSR review column, “Recent Reference Books,” by Frances Neel Cheney. “Reference Books in Print” includes all additional books received prior to the inclusion deadline established for this issue. Appearance in this column does not preclude a later review in RSR. Publishers are urged to send a copy of all new reference books directly to RSR as soon as published, for immediate listing in “Reference Books in Print.” Reference books with imprints older than two years will not be included (with the exception of current reprints or older books newly acquired for distribution by another publisher). The column shall also occasionally include library science or other library related publications of other than a reference character.

Project Censored/Media Freedom Foundation, a 35-year old media research group originally based at Sonoma State University, now operates in cooperation with over 30 college and universities worldwide. The Project encourages college instructors to use and validate independent news stories as part of student classroom research assignments. The 25 most important validated news stories are published annually in the Censored yearbooks from Seven Stories Press (see www.projectcensored.org/ for more details).
