Race-to-the-bottom or -top at home or abroad: Health and safety standards and the multinational firm

We develop a model to illustrate potential complexities in the relationship between corporate geographical diversification and the health and safety (H&S) standards set in national jurisdictions. A firm, that initially has a plant in its home country, may choose to also have one or two foreign plants in order to improve its bargaining position versus local governments, and so ensure reduced H&S standards, i.e. a race-to-the-bottom. However, contrary to the main focus of the popular debate on this topic, we note the potential for the race-to-the-bottom tendency to be exerted on H&S standards in the multinational company’s home rather than host country, and also for an upward push on H&S to instead result.

The effect of an adventure race on lymphocyte and neutrophil death

The effect of an adventure race (Ecomotion Pr), which lasted for 4-5 days, on neutrophil and lymphocyte death from elite athletes was investigated. Blood was collected from 11 athletes at rest and after the adventure race. The following parameters of cell death were measured in neutrophils and lymphocytes: cell membrane integrity, DNA fragmentation, mitochondrial transmembrane depolarization and reactive oxygen species (ROS) production. Phagocytosis capacity was also evaluated in neutrophils. The adventure race raised the proportion of cells with the loss of membrane integrity; lymphocytes by 14% and neutrophils by 16.4%. The proportion of lymphocytes with DNA fragmentation (2.9-fold) and mitochondrial transmembrane depolarization (1.5-fold) increased. However, these parameters did not change in neutrophils. ROS production remained unchanged in lymphocytes, whereas an increase by 2.2-fold was found in neutrophils due to the race. Despite these changes, the phagocytosis capacity did not change in neutrophils after the race. In conclusion, the Ecomotion Pr race-induced neutrophil death by necrosis (as indicated by the loss of membrane integrity) and led to lymphocyte death by apoptosis (as indicated by increase DNA fragmentation and depolarization of mitochondrial membrane).

The influence of sex, age, and race experience on pacing profiles during the 90 km Vasaloppet ski race

The purpose of this study was to investigate pacing-profile differences during the 90 km Vasaloppet ski race related to the categories of sex, age, and race experience. Skiing times from eight sections (S1 to S8) were analyzed. For each of the three categories, 400 pairs of skiers were matched to have a finish time within 60 seconds, the same start group, and an assignment to the same group for the other two categories. Paired-samples Student’s t-tests were used to investigate sectional pacing-profile differences between the subgroups. Results showed that males skied faster in S2 (P=0.0042), S3 (P=0.0049), S4 (P=0.010), and S1–S4 (P<0.001), whereas females skied faster in S6 (P<0.001), S7 (P<0.001), S8 (P=0.0088), and S5–S8 (P<0.001). For the age category, old subjects (40 to 59 years) skied faster than young subjects (19 to 39 years) in S3 (P=0.0029), and for the other sections, there were no differences. Experienced subjects (≥4 Vasaloppet ski race completions) skied faster in S1 (P<0.001) and S1–S4 (P=0.0054); inexperienced skiers (<4 Vasaloppet ski race completions) had a shorter mean skiing time in S5–S8 (P=0.0063). In conclusion, females had a more even pacing profile than that of males with the same finish time, start group, age, and race experience. No clear age-related pacing-profile difference was identified for the matched subgroups. Moreover, experienced skiers skied faster in the first half whereas inexperienced skiers had higher skiing speeds during the second half of the race.
