A Justice-Oriented Innovation System: A Grounded Theory Approach

Researchers are becoming increasingly concerned about integrating the goals of a social justice system with innovation and technical change. Although most of the previous studies concerned the dynamics of the relationship between innovation and social justice, a consistent solution for reconciling these two seemingly conflicting objectives has not been discovered as yet. Prior findings suggest several partial, incoherent, and even conflicting solutions. This paper examines the possibility of the above-mentioned integration goals. Grounded theory is applied to propose a consistent framework of solutions (at the national level), including an innovative social justice system, the necessary ontological supports, and the relevant domestic and international context. This paper also discusses the applicability and implications of this new framework for future research.     

Deducing drop size and impact velocity from circular bloodstains

An experimental study was done to determine the diameter and velocity of blood drops falling on a surface by measuring the size of bloodstains they produced and counting the number of radial spines projecting from them. Bloodstains were formed by releasing drops of pig blood with a range of diameters (3.0-4.3 mm) and impact velocities (2.4-4.9 m/s), onto four different flat surfaces (glass, steel, plastic, paper) with varying roughness (0.03-2.9 microm). High-speed photography was used to record drop impact dynamics. Bloodstain diameters and the number of spines formed around the rim of stains increased with impact velocity and drop diameter. Increasing surface roughness reduced stain diameter and promoted merging of spines, diminishing their number. Equations are presented that explicitly relate drop diameter and impact velocity to measurements of stain diameter and number of spines.
