Biomechanics of predator–prey arms race in lion, zebra, cheetah and impala

The fastest and most manoeuvrable terrestrial animals are found in savannah habitats, where predators chase and capture running prey. Hunt outcome and success rate are critical to survival, so both predator and prey should evolve to be faster and/or more manoeuvrable. Here we compare locomotor characteristics in two pursuit predator–prey pairs, lion–zebra and cheetah–impala, in their natural savannah habitat in Botswana. We show that although cheetahs and impalas were universally more athletic than lions and zebras in terms of speed, acceleration and turning, within each predator–prey pair, the predators had 20% higher muscle fibre power than prey, 37% greater acceleration and 72% greater deceleration capacity than their prey. We simulated hunt dynamics with these data and showed that hunts at lower speeds enable prey to use their maximum manoeuvring capacity and favour prey survival, and that the predator needs to be more athletic than its prey to sustain a viable success rate

Moving Towards a Culturally Diverse Accounting Profession

This paper discusses the increasing diversity in the accounting profession. Evidence is presented substantiating that over one third of recent accounting graduates are from ethnic minority backgrounds, the majority of whom are Asian/Pacific Islanders. In our university specific data, we find an even higher percentage (71%) of ethnic minorities receiving accounting degrees, with Asian/Pacific Islanders as the majority group. We also show that over one fourth of new accounting graduates hired by accounting firms are ethnic minorities of which fifty percent are Asian/Pacific Islanders

Movement patterns and athletic performance of leopards in the Okavango Delta

Although leopards are the most widespread of all the big cats and are known for their adaptability, they are elusive and little is known in detail about their movement and hunting energetics. We used high-resolution GPS/IMU (inertial measurement unit) collars to record position, activity and the first high-speed movement data on four male leopards in the Okavango Delta, an area with high habitat diversity and habitat fragmentation. Leopards in this study were generally active and conducted more runs during the night, with peaks in activity and number of runs in the morning and evening twilight. Runs were generally short (less than 100 m) and relatively slow (maximum speed 5.3 m s−1, mean of individual medians) compared to other large predators. Average daily travel distance was 11 km and maximum daily travel distance was 29 km. No direct correlation was found between average daily temperature and travel distance or between season and travel distance. Total daily energy requirements based on locomotor cost and basal metabolic rate varied little between individuals and over time. This study provides novel insights into movement patterns and athletic performance of leopards through quantitative high-resolution measurement of the locomotor, energetic, spatial and temporal movement characteristics. The results are unbiased by methodological and observational limitations characteristic of previous studies and demonstrate the utility of applying new technologies to field studies of elusive nocturnal species

The “F” Word?: An Analysis of the State of Feminism in the United States Today

Feminism is the attempt to reduce or eliminate patriarchy, or male rule by birthright. While this struggle for gender equality may seem straightforward, there are different “strains” of feminism that advocate different approaches to achieving feminist goals. The prevailing literature surrounding the state of modern feminism is vast —- often varying by the author’s political values, age relative to the early women’s rights movements, and beliefs about whether or not sex-based equality has been achieved. This paper, developed primarily from scholarly literature about modern feminism, will integrate findings from interviews with six women (three who are current students at Gettysburg College and three who are recent college graduates in the workforce) about their perceptions of feminism in order to introduce a theory of Postfeminist Dualism that aims to describe the state of feminism today. Postfeminist Dualism posits that there exists a divide between women who work intersectionally to reclaim the liberatory nature of traditional feminism and those who use the principles of feminism to justify personal advancement

Financial Innovation as a Competitive Strategy: The Kenyan Financial Sector

The world business environment is rapidly changing and becoming intensely competitive. In this context, most organizations are realizing that knowledge is the most important resource in creating sustainable competitive advantage. Knowledge management (KM) as a discipline is designed to provide strategy, process, and technology to increase organizational efficiency and effectiveness. The survival and success of a firm are dependent on the capacity of management to generate new ideas. One such a topical idea is financial innovations. Economies and businesses across the world have embraced creativity and innovation to circumvent market imperfections. Kenya as an economy has been hailed as a regional financial hub. This paper is a narrative review seeking to establish the extent of financial innovation in Kenya and how this enhances competitiveness. The research finds out that the Kenyan financial sector has made some remarkable strides towards financial innovations. However, it is noted that there is still enormous untapped potential that can enhance Kenya’s economy further. Keywords: knowledge management (KM), financial innovations, market imperfection

Towards a Global Learning Commons: ccLearn

Though open educational resources (OER) promise to transform the conditions for teaching and learning worldwide, there are many barriers to the full realization of this vision. Among other things, much of what is currently considered "free and open" is legally, technically, and/or culturally incompatible. Herein, the authors give a brief history of open education, outline some key problems, and offer some possible solutionsThis article was originally published in Educational Technology 4(6).
