Two experiments contrasted interactions between group leaders with interactions between individuals in a mixed-motive setting. Consistent with the idea that being accountable to the in-group implies normative pressure to benefit the in-group, Experiment 1 found that accountable leaders were more competitive than individuals. Consistent with the idea that being unaccountable to the in-group impl...

We study a model ecosystem by means of dynamical techniques from disordered systems theory. The model describes a set of species subject to competitive interactions through a background of resources, which they feed upon. Additionally direct competitive or co-operative interaction between species may occur through a random coupling matrix. We compute the order parameters of the system in a fixe...

Five methods that generate multiple prototypes from labeled data are reviewed. Then we introduce a new sixth approach, which is a modification of Chang’s method. We compare the six methods with two standard classifier designs: the 1nearest prototype (1-np) and 1-nearest neighbor (1-nn) rules. The standard of comparison is the resubstitution error rate; the data used are the Iris data. Our modif...

Globalization may have different impacts on the gender wage gap depending on the specialization and trade pattern as well as the socio-economic situation. The main purpose of this paper is to examine an impact of globalization on gender wage inequality. Specifically, the hypothesis is that globalization reduces gender wage gap. For this, we have employed a panel technique for 21 selected develo...

Blockchain has great potential for facilitating the development of construction industry but not been widely used to this end. The objective study was identify factors affecting adoption blockchain in from technical, organizational, and environmental dimensions with help theories related technology adoption. Empirical results showed that relative advantage, compatibility, competitive pressure, ...

This paper presents a comparative study of pressure-sensitive sensor materials being suitable for monitoring purposes in pressure mapping sensor networks. Four sensor materials working on piezoresistive, piezoelectric, quasi-piezoelectric and capacitive principle have been discussed including the built-up, the working principle, the manufacturing and the most important properties. Additionally,...

While gas discharges under atmospheric pressure occur as filamentary discharges, most studies on plasma polymerization, or plasma Chemical Vapour Deposition (CVD), were carried out in low-pressure (low temperature, non-equilibrium) plasma. However, it is reasonable to assume that the fundamentals of plasma polymerization found by low-pressure discharge apply to the gas phase in the filamentary ...

Fundamental crystal chemistry and first-principles total-energy calculations are used to examine stable and metastable high-pressure silica structures. We find that a large class of energetically competitive phases can be generated from hcp arrays of oxygen with silicon occupying one-half of the octahedral sites. Calculations for specific structures provide an explanation for a number of recent...
