Age-Related Attenuation of Dominant Hand Superiority

The decline of motor performance of the human hand-arm system with age is well-documented. While dominant hand performance is superior to that of the non-dominant hand in young individuals, little is known of possible age-related changes in hand dominance. We investigated age-related alterations of hand dominance in 20 to 90 year old subjects. All subjects were unambiguously right-handed according to the Edinburgh Handedness Inventory. In Experiment 1, motor performance for aiming, postural tremor, precision of arm-hand movement, speed of arm-hand movement, and wrist-finger speed tasks were tested. In Experiment 2, accelerometer-sensors were used to obtain objective records of hand use in everyday activities

Industrial Drivers of Co-opetition Among Organizations: A Sector-Based Research Within the Context of Population Ecology Approach

28th Eurasia-Business-and-Economics-Society (EBES) Conference -- MAY 29-31, 2019 -- Coventry Univ, Ctr Financial & Corporate Integr, Coventry, ENGLANDCo-opetition is the term which defines a hybrid behavior comprising competition and cooperation concurrently. Co-opetition strategy extends the traditional rules of competition and collaboration strategies. In this paper, we aimed to explain the co-opetition relationship between rivals by using the assumptions of the population ecology approach. We have collected data from two industries having different levels of entrant and exiting rates to compare population-originated drivers of co-opetitive relationships. We have evaluated generally the effect of entering and exiting of rivals in the industry on co-opetition tendency of firms in both industries. To embody the assumptions of population ecology approach, we have used age, size, and niche width of organizations. By compassion two industries we found that there is no difference among industries for getting co-opetition against entering and exiting of rivals in the industry in general. Despite age and size of firms does not lead to difference among industries, niche width is important for the firms in construction sector for getting co-opetition.Eurasia Business & Econ Soc,Coventry Business Sch Trading Floo
