Kinematic analysis of human movements

A phase of motion during which the relative positions of some body parts remain unchanged along trajectories Temporal organization Movements are organized and perceived in blocks

A movement can be understood in terms of a hierarchy of scales and approximated by the sum of a minimal set of linear trajectories with given accuracy Approximation of trajectories in a pirouette by straight lines Approximation of trajectories in a pirouette by plain curves (2D)

Movement analysis software developed: KAMCAD

The typical character of the movement ← the few major scales; The minor scales → individual movement traits; Such a functional separation of scales allows perceiving the movements categorically as the highly stylized figures of classical ballet. Towards an automated recognition of movements

How people organize their communications … in blocks of 10 minutes

Communication in organizations: a dynamic view (UNI VE + UNI BI) Data collection was carried out in June and July 2010 in two firms: H ‐ farm (a venture incubator:75 employees, 9 start-ups) and H ‐ art (in the media industry, 71 employees). We analyze communication schedules within an organization: a)The communication group size; b)The duration of communications; c)The duration of the interval between similar communications;

Communication events have neither characteristic sizes, …

min …nor characteristic durations This is a structure of communications (reflecting a structure of relationships) that is important.

Informative events are about 10 minutes Mutual information is a measure of how much knowing that X speaks would reduce uncertainty about Y expressed in the joint distribution of X and Y (summed over all pairs of collocutors)

Communication graphs: The nodes of the graphs represent individuals, and edges connecting them indicate non--‐zero probabilities of communication in the given duration.

Structure of communication graphs The most richly diverse structure is observed in the moderately connected communication graphs, but neither for the densely connected graphs (for the short communication duration), nor for loosely connected graphs (for long communication durations).

Conclusion on identification of levels in movements data, movement perception, spatio-temporal searching, communication … etc.

Hypothetical Kuznets curve Kuznets’ hypothesis (1950s): Market forces first increase and then decrease economic inequality. Anti-Kuznets curve

Income (GDP per capita) Inequality (IPLC) Hypothetical Kuznets curve Kuznets’ hypothesis (1950s): Market forces first increase and then decrease economic inequality. Anti-Kuznets curve (1992’$)

Income (GDP per capita) Inequality (IPLC) Anti-Kuznets curve (1992’$) The global economy depends upon investments: When the rate of return on capital significantly exceeds the growth rate of the economy, then it logically follows that inherited wealth grows faster than output and income, so that inherited wealth will dominate wealth amassed from a lifetime’s labor by a wide margin, and the concentration of capital will attain extremely high levels.

Income (GDP per capita) Inequality (IPLC) Anti-Kuznets curve (1992’$) periods of requiring concentration and diffusion of capital.. If political system allows redistribution of extremely centralized capital, then … Otherwise, the system sticks … … economy growth stops … elites (children of) fall into hypercompetition, and instability comes. ▪ Hypercompetition in elites destabilizes states; ▪ Instabilities multiply polities;

The World Top Income database tells us that Rapidly rising inequality marks wars/conflicts/ instabilities; Global synchronization of inequality dynamics;
