The Giant MagnetoResistance (GMR) effect, discovered in France in 1988, has already been applied in magnetic sensors and has promise in other applications. The rapid acceptance of this technology is due to GMR’s unique characteristics such as high sensitivity, good temperature stability, and excellent linearity over a wide sensing range. In this article GMR materials are described as are their application in magnetic field sensors. New GMR structures utilizing spin valves and spin dependent tunneling (SDT) will offer even more potential for expanding the horizon of solid state magnetic sensing. Comparisons are made to sensors using conventional technology. Integrated GMR sensors that have signal conditioning and output electronics monolithically integrated with the sensor offer further uses of this new technology. Beyond the sensor itself, other control system functions have the potential for using the same GMR materials to make magnetic isolators and nonvolatile memories.

Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

In recent years, theory and research have been increasingly devoted to understanding organizational behavior in cross-cultural and global contexts, with particular attention being paid to the appropriateness of various human resources management (HRM) practices because practices that may be effective within one cultural context may not be effective in other cultural contexts. This chapter argues that a multi-level perspective is needed to explain the interplay between HRM practices and employee responses across cultural contexts. Specifically, the multi-level framework developed in this chapter elucidates the importance of fit between HRM practices, individual values, organizational values, and societal values. Societal values play a key role in the adoption of HRM practices, and the effectiveness of these HRM practices will depend largely on “fit” or alignment with the values of the societal culture in which the organization is operating. HRM practices also shape the collective responses of employees through organizational climate at the organizational level and through psychological climate at the individual level. For positive employee attitudes and responses to emerge, the climate created by the HRM practices must be aligned with societal and individual values. Building on these notions, the strength of the societal culture in which the organization is operating serves as a mechanism that links relationships between climate, value fit, and attitudes across levels of analysis. The chapter concludes with some recommendations for future research and implications for practice.

Does staffing contribute to organizational effectiveness and sustained competitive advantage, or are many of staffing’s implications merely cross-level fallacies? This article provides a critical examination of staffing research and practice, and proposes a multilevel model of staffing that ties together micro (e.g. personnel selection), meso (e.g. team staffing), and macro (e.g. organizational strategy, Human Resources practices) theory, research, and practice. The model is both integrative and prescriptive, providing a basic organizing structure for examining staffing research within and across levels. The article begins with a review of multilevel theory, followed by a review and critique of the dominant staffing paradigms from a multilevel perspective. It is shown these single level paradigms cannot answer many of the primary questions of interest to staffing specialists. In contrast, the multilevel staffing model not only addresses these limitations, but also prompts a variety of new predictions that oftentimes run counter to prevailing wisdom. Staffing specialists are challenged to show how our science and practice contribute to better functioning organizations.

Organizations are considering the influence of workplace attention breadth (mindfulness and absorption) on professional development. Although corporate accountants typically focus on technical skills, soft skills such as mindfulness may also improve performance. In this study, we examine the influence of attention breadth on task performance by demonstrating how mindfulness and absorption vary with respect to improvement to entry, mid, and upper-level accounting tasks. We survey over 700 corporate accounting professionals and find that upper-level manager task performance is related to mindfulness, and mid-level manager task performance is associated with mindfulness and absorption. We also find that mid-level professionals who are unable to transition between mindfulness and absorption states serve a relatively longer tenure before advancing to an upper-level position. This study has important implications for management to assist in improving office productivity and morale.

Purpose – To explore the ideological effects and social control potential of diagnostic biopsychiatry and encourage the sociology of diagnosis to retain key insights of early medicalization scholarship.

Methodology – As the sociology of diagnosis emerges from medicalization, it is imperative that the new sub-specialty retains the critical edge of the early scholarship. With this in mind the paper reviews key aspects of the medicalization thesis, emphasizing the links between medical definitions and social control processes (e.g. Conrad, 1992; Conrad & Schneider, 1992; Zola, 1972). Based on this review scholars are urged to be mindful of the “diagnostic imaginary” -- a way of thinking that conceals the presence of the social in diagnoses, and which closes off critical analysis of the existential-connectedness and political nature of diagnoses.

Findings – The paradigm shift from dynamic to diagnostic psychiatry in DSM-III opened the door to a new biomedical model that has enhanced American psychiatry's scientific aura and prestige. With the increased presence and ordinariness of diagnoses in everyday life, an illusory view of diagnoses as scientific entities free of cultural ties has emerged, intensifying the dangers of medical social control.

Social implications – By illustrating that diagnoses are cultural objects imbued with political meaning, the ideological effects and social control potential of diagnostic biopsychiatry may be mitigated.
