In this paper I examine the intracultural variability of parental and alloparental caregiving among the Aka foragers of the Central African Republic. It has been suggested that maternal kin offer higher frequencies of allocare than paternal kin and that maternal investment in infants will decrease when alloparental assistance is provided. Behavioral observations were conducted on 15 eight- to t...

We present a generalization of spatial power indexes able to overcome their main limitations, namely: i) the excessive concentration of power measures; ii) the too high sensitivity to players’ location in the ideological space. Voters’ propensity to support an issue is modeled via a random utility function with two additive terms: the deterministic term accounts for voters’ preference-driven/pr...

Different initiatives are initiated to utilize ICT to maintain and develop democracy. Democracy models are developed to explain differences between different democracies. This paper reports from a case study where a webbased discussion board is developed and implemented. The findings indicate that politicians and citizens add support to different democracy models by their contributions to the w...

Data fusion is the final step of a typical data integration process, after schematic conflicts have been overcome and after duplicates have been correctly identified. We present the relational data fusion system FuSem, which uses schema mappings and information about duplicates to decide what to fuse, i.e., which tuples to merge into one. The aspect emphasized by the demo is how to fuse the dup...

In the demo, we demonstrate a mobile food recognition system with Fisher Vector and liner one-vs-rest SVMs which enable us to record our food habits easily. In the experiments with 100 kinds of food categories, we have achieved the 79.2% classification rate for the top 5 category candidates when the ground-truth bounding boxes are given. The prototype system is open to the public as an Android-...

Over the past twenty years, we have learned a great deal about the ways in which pervasive forces of transformation have enveloped the citizens and states of the former Soviet bloc. The analytic rubric of "postsocialism" has played a crucial role in this body of scholarship by enabling conversation and comparison among diverse studies spread across a massive region of the world. It is increasin...

A rectangular enclosure has such an even distribution of resonances that it can be accurately and efficiently modelled using a feedback delay network. Conversely, a nonrectangular shape such as a sphere has a distribution of resonances that challenges the construction of an efficient model. This work proposes an extension of the already known feedback delay network structure to model the resona...

The transformation laws of the general linear superfield V (x, θ, θ) and chiral superfields under N = 1 supertranslations exp[i(ζ ·Q+Q · ζ)] are tabulated to all orders in the parameters ζ , ζ.

A (t, s, v)-all-or-nothing transform is a bijective mapping defined on s-tuples over an alphabet of size v, which satisfies the condition that the values of any t input co-ordinates are completely undetermined, given only the values of any s− t output co-ordinates. The main question we address in this paper is: for which choices of parameters does a (t, s, v)-all-or-nothing transform (AONT) exi...
