The Impact of Operating and Financial Risk on Equity Risk

Abstract: This paper empirically investigates a complete theoretical model relating the operating characteristics of a firm to the total, systematic, and unsystematic risk of its equity. The degree of operating leverage, the ratio of net profits to firm value, and the variability of unit output are all found to be positively correlated with each of the three risk measures. The degree of financial leverage, while positively related to total and unsystematic risk, does not appear to be related to systematic risk. After controlling for the business risk of the firm, no evidence can be found of an interaction between the degree of operating leverage and the degree of financial leverage.

Acute Effects of Dietary Ginger on Quadriceps Muscle Pain During Moderate-Intensity Cycling Exercise

Abstract: Ginger has known hypoalgesic and anti-inflammatory properties. The effects of an oral dose of ginger on quadriceps muscle pain, rating of perceived exertion (RPE), and recovery of oxygen consumption were examined during and after moderateintensity cycling exercise. Twenty-five college-age participants ingested a 2-g dose of ginger or placebo in a double-blind, crossover design and 30 min later completed 30 min of cycling at 60% of VO2peak. Quadriceps muscle pain, RPE, work rate, heart rate (HR), and oxygen uptake (VO2) were recorded every 5 min during exercise, and HR and VO2 were recorded for 20 min after exercise. Compared with placebo, ginger had no clinically meaningful or statistically significant effect on perceptions of muscle pain, RPE, work rate, HR, or VO2 during exercise. Recovery of VO2 and HR after the 30-min exercise bout followed a similar time course in the ginger and placebo conditions. The results were consistent with related findings showing that ingesting a large dose of aspirin does not acutely alter quadriceps muscle pain during cycling, and this suggests that prostaglandins do not play a large role in this type of exercise-induced skeletal-muscle pain. Ginger consumption has also been shown to improve VO2 recovery in an equine exercise model, but these results show that this is not the case in humans.

Attribution of Causality by Children with Alcoholic Parents

Abstract: Thirty children (ages 7–12), 15 from homes with parent(s) having a severe drinking problem and 15 from homes where no drinking problem existed, were given the children's Nowicki-Strickland Internal-External Control Scale. Comparison of the groups indicated that children from severe problem-drinking homes had higher externality scores than children from homes where no drinking problem existed. These differences may be due to different socialization experiences of the children.

Environmental Management Accounting: The State Of Play

Abstract: Environmental management accounting (EMA) is characterised by a lack of standard taxonomy. Minimal consensus, either in terminology or definitions, has been a feature of the literature. This paper seeks to not only provide a structured overview of the extant literature on environmental management accounting, but to do so in a manner that allows the reader to better understand the key issues and concerns. The private cost approach suggests that corporate environmental outcomes should be part of the characteristic management accounting undertaken by a firm. Conversely, the external cost approach suggests that only by recognizing externalities or the non-market costs imposed on society by firms, will management accounting deliver the required level of environmental outcomes.

Comparative isotopic evidence from East Turkana supports a dietary shift within the genus Homo.

Abstract: It has been suggested that a shift in diet is one of the key adaptations that distinguishes the genus Homo from earlier hominins, but recent stable isotopic analyses of fossils attributed to Homo in the Turkana Basin show an increase in the consumption of C4 resources circa 1.65 million years ago, significantly after the earliest evidence for Homo in the eastern African fossil record. These data are consistent with ingesting more C4 plants, more animal tissues of C4 herbivores, or both, but it is also possible that this change reflects factors unrelated to changes in the palaeobiology of the genus Homo. Here we use new and published carbon and oxygen isotopic data (n = 999) taken from large-bodied fossil mammals, and pedogenic carbonates in fossil soils, from East Turkana in northern Kenya to investigate the context of this change in the isotope signal within Homo. By targeting taxa and temporal intervals unrepresented or undersampled in previous analyses, we were able to conduct the first comprehensive analysis of the ecological context of hominin diet at East Turkana during a period crucial for detecting any dietary and related behavioural differences between early Homo (H. habilis and/or H. rudolfensis) and Homo erectus. Our analyses suggest that the genus Homo underwent a dietary shift (as indicated by δ13Cena and δ18Oena values) that is (1) unrelated to changes in the East Turkana vegetation community and (2) unlike patterns found in other East Turkana large mammals, including Paranthropus and Theropithecus. These data suggest that within the Turkana Basin a dietary shift occurred well after we see the first evidence of early Homo in the region. Carbon and oxygen isotope analysis of sediments and soils from hominin locales in Kenya coupled with results from hominin taxa suggest that a dietary shift from C3 to C4 resources occurred in the genus Homo circa 1.65 million years ago despite palaeoenvironmental continuity.
