In this chapter, we outline the statistical consequences of neglecting structural breaks and regime switches in autoregressive and GARCH models and propose two strategies to approach the problem. The first strategy is to identify regimes of constant unconditional volatility using a change point detector and estimate a separate GARCH model on the resulting segments. The second approach is to use a multiple-regime GARCH model, such as the Flexible Coefficient GARCH (FCGARCH) specification, where the regime-switches are governed by an observable variable. We apply both alternatives to an array of financial time series and compare their forecast performance.

This chapter presents a case which illustrates how the external management consultant may function as an organizational anthropologist and provide insights and alternative strategies for human resource professionals and leadership faced with high toxicity levels. The long-term failure to timely detect toxins and intervene in a destructive conflict results in the spread of dysfunctional behavior in the case company, pointing to leadership negligence and malpractice. The deeply entrenched “no emotions allowed” culture evokes massive turnover and plunging motivation and productivity. The case concludes with specific recommendations for avoiding or repairing a toxic workplace culture.

This study explores the simultaneous transitions in Palestine/Israel and South Africa at the end of the 20th century through an analysis of the shifting geography of Johannesburg and Jerusalem. After analyzing the relationship between political, economic and spatial restructuring, I examine the walled enclosures that mark the landscapes of post-apartheid Johannesburg and post-Oslo Jerusalem. I conclude by arguing that these walled enclosures reveal several interconnected aspects of the relationship between neo-liberal restructuring and the militarization of urban space. They also exemplify different configurations of sovereignty under conditions of neo-liberalism and empire.
