A case is presented for the active intervention of ethnographers in workplace settings they study. The author’s reasons for this position are discussed, as is its links to various social theories; and some of the flaws in the position are addressed.

The calotypes made by D. 0. Hill and R. Adamson have recently attracted much attention as beautiful examples of early photography.1 One of these is of considerable medical interest, portraying a woman with a large goitre (see fig.). It exists apparently in one copy only, held at the Scottish National Portrait Gallery. The chair in which the subject is sitting and the dry foliage behind her appe...

Many of you sitting here today were present at the first International Crop Science Congress in 1992. Looking around the room you will recognise several of your neighbours. They may have reached more senior positions and of course their publications lists are longer. Fortunately, there are also a few more women and there is a new generation of young scientists among us. But overall, not much se...

We examine the relationship between birth-to-birth intervals and a variety of mid- and long-term cognitive and socioeconomic outcomes, including high school GPA, cognitive ability, educational attainment, earnings, unemployment status, and receiving government welfare support. Using contemporary Swedish population register data and a within-family sibling comparison design, we find that neither...

We tested the hypothesis that engagement in a few, brief writing assignments in a nonmajors science course can improve student ability to convey critical thought about science. A sample of three papers written by students (n = 30) was coded for presence and accuracy of elements related to scientific writing. Scores for different aspects of scientific writing were significantly correlated, sugge...

methods in this study, 16 skilled female gymnasts (mean age of 9.62 ± 1.45 years) were randomly categorized to two general warm-up with no stretching (ns, n=8) and general warm-up plus static stretching (ss, n=8) groups. the warm-up protocol included a 10-minute jogging, and the static stretch (ss) protocol included stretching programs on the different parts of body during four weeks, three tim...

Due to the complexity of applying a well-defined stretch during human walking, most of our knowledge about the short latency stretch reflex modulation in humans is based on H-reflex studies. To illuminate the difference between the two methodologies, both types of reflexes were evoked in the same subjects, same experiment. Stretch reflexes were evoked via a stretch device capable of evoking str...

The purpose of the present study was to investigate how stretch reflex (SR) responses in the ankle extensor (soleus: SOL) and flexor (tibialis anterior: TA) muscles would be modulated with temporal and/or spatial predictions of external perturbations and whether their effects are specific to the standing posture. SR responses in the SOL/TA were elicited by imposing quick ankle toes-up/toes-down...

background: human body posture influences on his/her physiological functions. the purpose of this study was to investigate the effect of forward shoulder correction on pulmonary function of elementary female students. methods: subjects of this quasi-experimental research were two groups (n=20) of students with normal posture (np) and forward shoulder posture(fsp)  which is divided randomly into...

water quality aspect with regard to dissolved oxygen was studied for a 24 kilometer stretch of malaprabha river in karnataka state, india. main objective of the research was to simulate the predicted dissolved oxygen depletion due to the waste load allocation in the river with the ambient observed values of dissolved oxygen, and to ascertain the application of mathematical modeling for predicti...
