Abstract

Some cycle routes have proved unpopular because at several points a cyclist has to stop or slow very appreciably. Cyclists are discouraged by the resulting extra journey time. Three alternative hypotheses are made for a cyclist's performance in response to an imposed stop. In all he brakes uniformly from a cruising speed. In one, this speed is a personal standard, and he accelerates uniformly to regain it. In the second, because his energy is used in accelerating, he has less to use in cruising. The third hypothesis is that a cyclist's power output in accelerating is the same as in cruising, except at very low speeds, so that he attains his normal cruising speed asymptotically.

Trials were conducted on a lightly trafficked 2.5-km circuit with seven roundabouts. Cyclists made at least two circuits each, one non-stop and one stopping at roundabouts. Pairs of times for each cyclist were compared with derivations from each hypothesis. It was found that the estimates derived from the second hypothesis were much closer to the trial times than those given by the others. The conclusion is that making an adult cyclist stop is equivalent to extending the journey time by as much as an extra 50 m, approximately, would take. In reckoning the lengths of routes in order to select one for development, an equivalent distance of about 50 m should be added for each stop or near stop, unless they are close together.

Abstract

This chapter does three things. First, it estimates regional gross domestic product (GDP) for three different geographical levels in Switzerland (97 micro regions, 16 labor market basins, and 3 large regions). Second, it analyzes the evolution of regional inequality relying on a heuristic model inspired by Williamson (1965), which features an initial growth impulse in one or several core regions and subsequent diffusion. Third, it uses index number theory to decompose regional inequality into three different effects: sectoral structure, productivity, and comparative advantage.

The results can be summarized as follows: As a consequence of the existence of multiple core regions, Swiss regional inequality has been comparatively low at higher geographical levels. Spatial diffusion of economic growth occurred across different parts of the country and within different labor market regions. This resulted in a bell-shaped evolution of regional inequality at the micro regional level and convergence at higher geographical levels. In early and in late stages of the development process, productivity differentials were the main drivers of inequality, whereas economic structure was determinant between 1888 and 1941. The poorest regions suffered from comparative disadvantage, that is, they were specialized in the vary sector (agriculture), where their relative productivity was comparatively lowest.

Abstract

A brief review of merger and acquisition (M&A) publications, while indicating high failure rates, also indicate that few studies have neither focused on the pre-merger period nor the contributions from leaders and managers, and especially during that period. Additionally, there are limited “behavioral due diligence” (BDD) assessment(s). This chapter begins with a brief overview of definitions. It continues with a data-driven presentation focused on the limited publications and research of M&A pre-mergers (compared with the post-M&A period). This is followed by discussions on M&A-related BDD and leader/manager tasks, activities, and issues. These dialogues set the foundation for M&A actions, and research, focused on leaders and managers relative to BDD in the pre-merger phase. This chapter will close with recommendations of “going forward” and a conclusion.

Abstract

This chapter aims to make sense of the growing research that examines the role of culture in mergers and acquisitions. We provide a detailed review of the many related but distinct constructs that have been introduced to the literature. While each construct has contributed to our understanding of the role of culture, the lack of connections made among constructs has limited the consolidation of contributions. The review shows what these constructs mean for mergers and acquisitions, what major findings have been discovered, and, most importantly, how constructs interrelate. Our discussion provides several opportunities to foster the needed consolidation of this research.

Abstract

The purpose of this paper is to report about the presence of misconceptions in the historical thinking of fifth-grade children with learning disabilities (LD) and their normally achieving (NA) peers. We also sought to determine the effects of implementing an integrated instructional unit about 19th century U.S. Westward Expansion on children's historical misconceptions. This unit was taught over an eight-week period by a special education teacher (subsequently referred to as Ms. M) who had approximately two years of prior professional teaching experience. In addition to quantitative information about changes in children's content knowledge, we report interview data about children's understanding of historical content and historical reasoning. Furthermore, we captured on videotape approximately 12h of classroom instruction. Ms. M and the first author of this paper independently reviewed and then discussed these videotapes for the purpose of assessing the effects of her teaching practices on the development of children's historical understanding. The implications of our findings are discussed.

Abstract

Many announced cross-border mergers and acquisitions (M&As) are never brought to completion despite potential negative consequences to acquirers and targets. This paper presented evidence on the dynamic effects of spatial distance and two industry-level characteristics, namely industry relatedness between the two firms and technological intensity, on the completion likelihood of cross-border M&A deals. Based on a sample of 8,489 M&A transactions we found that the completion likelihood of cross-border M&As increases with spatial distance. The effect is more pronounced for deals across technology-based industries, evidence for related deals is inconclusive.

Abstract

Hashem Pesaran has made many seminal contributions, among others, in the time series econometrics estimation and forecasting under structural break, see Pesaran and Timmermann (2005, 2007), Pesaran, Pettenuzzo, and Timmermann (2006), and Pesaran, Pick, and Pranovich (2013). In this chapter, the authors focus on the estimation of regression parameters under multiple structural breaks with heteroskedasticity across regimes. The authors propose a combined estimator of regression parameters based on combining restricted estimator under the situation that there is no break in the parameters, with unrestricted estimator under the break. The operational optimal combination weight is between zero and one. The analytical finite sample risk is derived, and it is shown that the risk of the proposed combined estimator is lower than that of the unrestricted estimator under any break size and break points. Further, the authors show that the combined estimator outperforms over the unrestricted estimator in terms of the mean squared forecast errors. Properties of the estimator are also demonstrated in simulations. Finally, empirical illustrations for parameter estimators and forecasts are presented through macroeconomic and financial data sets.

Abstract

Even more than 50 years after the Civil Rights Act of 1964 prohibited discrimination toward a number of groups in employment settings in the United States, workplace discrimination remains a persistent problem in organizations. This chapter provides a comprehensive review and analysis of contemporary theory and evidence on the nature, causes, and consequences of discrimination before synthesizing potential methods for its reduction. We note the strengths and weaknesses of this scholarship and highlight meaningful future directions. In so doing, we hope to both inform and inspire organizational and scholarly efforts to understand and eliminate workplace discrimination.

Abstract

We review the state of the literature concerning work–family conflict in the military, focusing on service members’ parenting roles and overall family and child well-being. This includes recognition that for many women service members, parenting considerations often arise long before a child is born, thereby further complicating work–family conflict considerations in regard to gender-specific conflict factors such as pregnancy, childbirth, postpartum, and breastfeeding. Subsequently, we consider more gender-invariant conflict factors, such as the nature of the work itself as causing conflict for the service member as parent (e.g., nontraditional hours, long separations, and child care challenges) as well as for the child (e.g., irregular contact with parent, fear for parent’s safety, and frequent relocations), and the ramifications of such conflict on service member and child well-being. Finally, we review formalized support resources that are in place to mitigate negative effects of such conflict, and make recommendations to facilitate progress in research and practice moving forward.
