‘With almost electric speed’: mapping African American abolitionists in Britain and Ireland, 1838–1847

African American abolitionists made an indelible mark on nineteenth-century transatlantic society: their lectures were held in famous meeting halls, taverns, theatres, churches, and the private parlour rooms of wealthy patrons across the British Isles. This article will demonstrate how digital mapping techniques reveal not only the extent of how far African Americans travelled, but also how visualizing their tours can lead to new avenues of research. Digital mapping can reinvigorate scholarship on transatlantic activism by providing original insights into journeys by men such as Frederick Douglass and Moses Roper.     

Playing the scales: Regional transformations and the differentiation of rural space in the Chilean wine industry

Globalization and industrial restructuring transform rural places in complex and often contradictory ways. These involve both quantitative changes, increasing the size and scope of operation to achieve economies of scale, and qualitative shifts, sometimes leading to a shift up the quality/price scale, towards finer spatial resolution and identification with place of origin. This paper examines the transformation of the Chilean wine industry noting its expansion and orientation towards export production. As the industry has changed, it has become apparent that firms have adopted different scalar strategies, sometimes downscaling by seeking low-cost production, homogenisation of product and a weak identification with place, and sometimes upscaling by improving quality, claiming exclusiveness and fixing products to ever finer definitions of place. Places have been defined, reconstructed, promoted and significantly differentiated as a result.     

Noisy zones of proximal development: Conversation in noisy classrooms

Despite the importance of context in studies of language use, sociolinguists have ignored the impact of noise on conversational interaction. This inattention is of particular concern in classrooms where language is a learning tool. Our research on interaction in noisy settings took place in English language elementary school classrooms with students in grades 3, 5, and 7, whose first language was English. Students were observed during regular classroom activities. Employing a novel method, in which students wore ear‐level microphones, we obtained stereophonic recordings of the noise and conversation that reached each listener's ears. A dosimeter measured the noise levels in each classroom. Analyses of students’ patterns of conversation suggest that noise levels impeded the intended development of complex conversational interaction and collaborative learning. This study also questions the place of acoustics in understanding context, and the significance of the hearer's perspective in sociolinguistic studies of conversational interactions.     

Fertility and development in Brazil

In the past, one of the concomitants of development has been a sustained reduction in fertility. As a result of this experience, demographers hypothesize that in a society in which fertility is lower in urban areas, among the upper socioeconomic status groups and the better-educated, fertility will decline to a moderate level as the country changes from a rural, agricultural socioeconomic structure, with low levels of living and education, to an urban, industrial structure, with rising levels of living and education.The data analyzed in this study indicate, however, that though substantial social and economic development (as measured by changes in industrial structure, per capita income, urbanization, and education) occurred in Brazil from at least 1920-40 to 1960, during which time fertility differentials of the kind indicated above existed, fertility has shown little or no tendency to decline. Between 1940 and 1960, in fact, the birth rate appears to have remained fairly constant around 43. With the death rate steadily dropping, the rate of natural increase and population growth (given a small net in-migration) has been accelerating. p ]From a theoretical point of view, these facts reinforce a growing realization, based on similar findings in some other developing countries, that the prevailing theoretical ideas concerning the relationship between development and fertility require modification, particularly in the direction of greater specificity. On the practical side, the question is raised whether Brazil's rate of economic development during the postwar period up to 1960 can be maintained, let alone increased, in the face of a population growth rate which will probably average 3.2-3.5 percent for the period 1960-70 and which, in the absence of a decline in fertility, is likely to accelerate further.     

Private Polls and Presidential Policymaking: Reagan as a Facilitator of Change

Did the Reagan administration disregard majority will when craftingits policy initiatives? Did it cater to a narrow partisan constituencyinstead? The answers to these questions will help with an assessmentof Jacobs and Shapiro’s (2000b) hypothesis that presidentssince the late 1970s have used private White House survey researchas a tool to manipulate or assuage centrist public opinion whilemeeting the policy demands of their partisan core supporters,resulting in a decline in presidential responsiveness to majoritywill. Using the actual surveys administered by Richard Wirthlin(Reagan’s pollster) between 1981 and 1983, this articlewill demonstrate the level of consistency between majority opinionon 129 policy issues and Reagan’s behavior through 1984,and it will explore the conditions under which the presidentwas more or less likely to respond to public preferences. Thedata reveal that the Reagan administration was constrained bythe popular will in predicable ways: if the policy issues wereabout domestic concerns, highly popular, and visible in themedia, then the administration acted in line with public preferencesmore than 70 percent of the time. Further, Reagan and his adviserswere selective in responding to party activists: they championedissues drawn from their conservative ideological agenda thatfit with the current tide in public opinion, while sidesteppingother issues dear to party activists that encountered strongmajority resistance. While I do not contest Jacobs and Shapiro’s(2000b) important observation that presidents often use surveyresearch to "craft talk" in an attempt to channel the publicdebate, the evidence here highlights how the president nonethelessremains constrained by the popular will, at least on domesticissues.

A Multiple Objective Embedded Network Model for Human Resource Planning and an Implementation of the Tchebycheff Method

A multiple objective embedded network model is proposed to model a variety of human resource planning problems including executive succession planning, compensation planning, training program design, diversity management and human systems design. The Tchebycheff Method, an interactive multiple objective programming solution procedure developed by Steuer and Choo [32], is implemented using NETSIDE, a computer routine for solving network problems with side constraints developed by Kennington and Whisman [17]. This paper demonstrates how the network structure common to many types of human resource planning problems can be exploited to improve solution efficiency, and how our approach extends the use of network models in human resource planning by including multiple objectives and extranetwork constraints. An illustrative example demonstrating the modeling and solution approach is presented, and the potential applications of these approaches in two specific areas of human resource planning are discussed.
