Study of Size Effect in Sheet-stringer Panels

An investigation was conducted to determine whether there are significant size effects in compressive strength of large Z-stiffened sheet-stringer panels as compared with geometrically similar smaller models and thus to ascertain whether the prediction of the strength of large panels by model tests is reliable. The specimens studied were manufactured from 7075-T6 aluminum alloy and included four representative types of panel designs, with full- and one-quarter-scale panels of each type

A Positive Theory of Legislative Intent

The debate about statutory interpretation has been affected by the introduction of social choice theory into the study of legal institutions. The positive political theory of legislative intent is examined

Merrell Dow Pharmaceuticals, Inc.

The Federal Rules of Evidence exclude expert scientific testimony when it has been developed without regard for accepted scientific methods. This case focuses on expert scientific evidence. Such evidence plays a vital and often dispositive role in modern litigation. For scientific evidence to be helpful to the factfinder it must meet some minimal threshold of reliability. To hold otherwise would be to allow a system of adjudication based more on chance than on reason

Lipid levels and emotional distress among healthy male college students

Low lipid levels have been found in some studies to be associated with non-illness deaths (i.e. suicides, homicides and accidents). Likewise, low lipids have been associated with measures of emotional distress (e.g. anxiety, depression, hostility) in medical, psychiatric and forensic populations whose age, health status and/or personal habits make interpretation of the association problematic. The present study examined the relationship of lipid levels to emotional distress in young, healthy, male college students. To investigate possible confounding/mediating relationships, a number of clinical risk factors and demographic variables were also studied (age, drug use, alcohol use, nicotine use, exercise, obesity and resting hemodynamic values). Bivariate correlations showed that measures of emotional distress (SCL-90-R subscales, Toronto Alexithymia Scale) and clinical/demographic factors (alcohol use, age, blood pressure, weight and heart rate) were associated with lipid levels. In a hierarchical set multiple regression, only alcohol use, age, resting systolic blood pressure and the positive symptom total from the SCL-90-R were unique correlates of total cholesterol. These results add additional support to the growing evidence of an association between lipid levels and emotional functioning. Importantly, this relationship appears to exist apart from other risk factors. While various studies have focused on specific dimensions of emotional distress (i.e. anxiety, depression, hostility), the results of the present study suggest that more global measures of emotional distress might better account for the association with lipid levels.

Tactile Presentation of Network Data: Text, Matrix or Diagram?

Visualisations are commonly used to understand social, biological and other kinds of networks. Currently, we do not know how to effectively present network data to people who are blind or have low-vision (BLV). We ran a controlled study with 8 BLV participants comparing four tactile representations: organic node-link diagram, grid node-link diagram, adjacency matrix and braille list. We found that the node-link representations were preferred and more effective for path following and cluster identification while the matrix and list were better for adjacency tasks. This is broadly in line with findings for the corresponding visual representations.Comment: To appear in the ACM CHI Conference on Human Factors in Computing Systems (CHI 2020
