The mechanics of running have been studied for hundreds of years. With the increase in interest in running as a recreational activity in recent years, running-related injuries have become common. Hundreds of studies on the mechanics of running have been conducted over the past few decades. However, the relationship between the mechanics of running and injury is still not well understood. This article describes the evolution of the study of the mechanics of running, with a focus on their relationship to injury. A brief historical review is presented, followed by a summary of the era of descriptive research and, finally, an overview of the more recent generation of hypothesis-driven research. The article concludes with suggestions for future research that may lead to greater insight into the relationship between lower-extremity biomechanics and injury.

The Relationship

Tocopherols and tocotrienols are natural compounds of plant origin, available in the nature. They are supplied in various amounts in a diet, mainly from vegetable oils, some oilseeds, and nuts. The main forms in the diet are α- and γ-tocopherol, due to the highest content in food products. Nevertheless, α-tocopherol is the main form of vitamin E with the highest tissue concentration. The α- forms of both tocopherols and tocotrienols are considered as the most metabolically active. Currently, research results indicate also a greater antioxidant potential of tocotrienols than tocopherols. Moreover, the biological role of vitamin E metabolites have received increasing interest. The aim of this review is to update the knowledge of tocopherol and tocotrienol bioactivity, with a particular focus on their bioavailability, distribution, and metabolism determinants in humans. Almost one hundred years after the start of research on α-tocopherol, its biological properties are still under investigation. For several decades, researchers’ interest in the biological importance of other forms of vitamin E has also been growing. Some of the functions, for instance the antioxidant functions of α- and γ-tocopherols, have been confirmed in humans, while others, such as the relationship with metabolic disorders, are still under investigation. Some studies, which analyzed the biological role and mechanisms of tocopherols and tocotrienols over the past few years described new and even unexpected cellular and molecular properties that will be the subject of future research.

The Relationship

Since the 1960s, Australian scientists have speculated on the impact of human arrival on fire regimes in Australia, and on the relationship of landscape fire to extinction of the Pleistocene megafauna of Australia. These speculations have produced a series of contrasting hypotheses that can now be tested using evidence collected over the past two decades. In the present paper, I summarise those hypotheses and review that evidence. The main conclusions of this are that (1) the effects of people on fire regimes in the Pleistocene were modest at the continental scale, and difficult to distinguish from climatic controls on fire, (2) the arrival of people triggered extinction of Australia’s megafauna, but fire had little or no role in the extinction of those animals, which was probably due primarily to hunting and (3) megafaunal extinction is likely to have caused a cascade of changes that included increased fire, but only in some environments. We do not yet understand what environmental factors controlled the strength and nature of cascading effects of megafaunal extinction. This is an important topic for future research.

This chapter reveals that the term ‘consumerism' encompasses a number of meanings which create confusion regarding the term. The discussion that follows, attempts to distinguish the different perspectives regarding the term by presenting its historical development and discussing the three definitions that have marked it. It explores the relationship between consumerism, marketing and corporate social responsibility (CSR). The growth of consumerism has led to the over-use of marketing which provided a flourishing ground for compulsive buying and consumption. There is evidence in the literature to suggest that in an era of increasing social problems and environmental challenges, there is a need for CSR and sustainable marketing. In fact, the second definition of consumerism is inextricably linked with CSR and societal marketing. The chapter is conceptual in nature and provides an in-depth review and discussion of some fundamental dimensions associated to consumerism based on the existent literature. The overarching aim is to provide an insight into the evolution and growth of consumerism based on the existent literature related to the topic. The discussion also focuses on exploring the relationship between marketing and consumerism shedding light onto compulsive buying, consumer attitudes and concerns on the micro consumerism issues, sustainable consumption and sustainable marketing. The chapter proceeds to raise some concerns related to the impact of the global economic crisis on consumerism by using as an example Cyprus based on the author's observations and thoughts. The chapter concludes with a list of suggestions to practitioners and directions for future research.

This chapter focuses on teacher leadership, an important variable in the classroom and school improvement literature. The concept of teacher leadership has attracted increased attention in the past two decades. Teachers are assuming more responsibility for leadership roles and functions within schools. Despite the considerable amount of scholarly effort and time spent on investigating the teacher leadership concept, less is known about how it flourishes in the school context and how it relates to classroom and school improvement. Therefore, this chapter tries to shed some light on the teacher leadership concept and discusses its meaning, teacher leadership roles, factors influencing teacher leadership, the relationship between teacher leadership and classroom and school improvement, and future research areas on teacher leadership. Offering a framework for teacher leadership, this chapter is expected to contribute well to the guidance of further research on teacher leadership.

Notwithstanding the increasing interest in open source ERP (OS-ERP) products in the past few years, their adoption by Belgian organizations is still very limited. To gain more insight into this phenomenon, we performed an exploratory investigation of which barriers inhibit the adoption of OS-ERP by Belgian SMEs. Based upon our previous research, we identified two main barriers, namely a lack of functionality and a lack of support. Next, we performed a screening of the Belgian OS-ERP market to investigate the functionality and support offered by various OS-ERP products. This allowed us to determine how the perceptions of organizations compare to the actual market for OS-ERP in Belgium. Our results provide more insight into the barriers to the adoption of OS-ERP by Belgian SMEs and provide various avenues for future research.

This chapter discusses the historiographical context in which this book is situated, and the scholarly debates to which it seeks to contribute. The chapter also presents the methodological framework of the book and examines the historical and historiographical benefits of a microhistorical analysis. The chapter shows that the story of Carlo Calà and his allegedly holy ancestor enables us to understand better important political, cultural, and theological aspects of early modern Catholicism. The chapter also puts the past in conversation with the present by suggesting that studying how the Roman Inquisition dealt with the problem of discerning the truth from the fake can provide insight into the relationship between truth, authenticity, and belief.

Insight Into

Over the past decade, universities have invested heavily in startup accelerator programs; however, their role in the university entrepreneurial ecosystem is ambiguous. Are university startup accelerators intended to educate or are they created to facilitate business starts and to contribute to regional economic development? In contrast, most private-sector startup accelerators serve a consistent and differentiated role in the entrepreneurial ecosystem—they provide programming and resources to startups to increase the probability of a return on investment. Understanding the role of university startup accelerators is an important precursor to evaluating their impact and whether or not the return is worth the considerable investment. In this study, we poll university accelerator directors to gain their perspective on the role(s) that university startup accelerators play and to identify how they are structured and operated. Our research reveals a fairly uniform structure and mode of operation. While facilitating business starts is a key role for some, it confirms education as the primary role for university startup accelerators. We outline appropriate means of assessing the learning that takes place in accelerator programs, offer insight into how these findings can help accelerator directors deliver on outcomes and demonstrate impact, and propose avenues for future research.

The Relationship

SummaryOver the past 25 years much effort has been put into the research of the relationship between neuropsychiatric disorders and the concentrations of CSF-monoamine metabolites. Most of this research has beenfocused on the relation between CSF-concentrations of 5-hydroxyindoleacetic acid (5-HIAA) and homovanillic acid (HVA) and specific symptomatological entities, particularly schizophrenia, Alzheimer's dementia and endogenous depression. It appeared that specific relations between diseases and CSF-concentrations of monoamine metabolites cannot be longer maintained and that a more functional psychopathology should be considered as the future research strategy.

Ullman’s review of empirical studies of rape avoidance is updated to illuminate what has been learned in the past 10 years and what is needed to continue to promote this important form of secondary prevention. Following a brief historical review, empirical studies of resistance strategies to sexual assaults since 1997 are reviewed. Studies of the effects of situational factors, rapist types, and victim-offender relationships on women’s resistance are included. Selected literature on self-defense training and rape prevention related specifically to women’s resistance also are reviewed, as these related areas of research have grown substantially in the past decade and can inform intervention and prevention efforts with women. Recommendations for future research and practice are offered.

Abstract The aim of the present contribution is twofold. On the one hand we shall discuss the background of some Islamic legends about places and wondrous objects – holy relics of the past – that had once been in the possession of the Gothic monarchy by inheritance, but were subsequently lost or looted out of al-Andalus by the Muslim leaders. On the other hand our study is concerned with the relationship between the content of the legends in question and the “loss of Spain” in a more general sense, i.e. not only the loss of these objects by the Christian Goths subsequent to their loss of power in Spain, but also their disappearance from Muslim ownership. Besides, the legends possess a moral core, which is interesting in its own right: the way in which they are viewed in the Muslim sources, the locations and objects they describe, and their relationship to the Gothic monarchy may provide the modern reader with an insight into the striking vision of the past held by the invading Muslim culture.
