This paper contributes to the knowledge about how educational investments are allocated across siblings within the household. More specifically I focus on investigating whether there are signs of diversification, formal schooling being a risky investment. The data used is unusual in that it includes the head of household’s risk preferences in addition to school-related and other information. Th...
Core assets are reusable artifacts built to be used in different software products in the same family. As such, core assets need to capture both commonality that exists and variability that is allowed in the product family (line). These assets are later utilized for guiding the creation of particular valid products in the family. Feature-oriented and UML-based methods have been proposed for mod...
Recent years have witnessed the rise of ancient DNA (aDNA) technology, allowing comparative genomics to be carried out at unprecedented time resolution. While it is relatively straightforward to use aDNA to identify recent genomic changes, it is much less clear how to utilize it to study changes in epigenetic regulation. Here we review recent works demonstrating that highly degraded aDNA still ...
Motivated by the Erdős multiplication table problem we study the following question: Given numbers N1, . . . , Nk+1, how many distinct products of the form n1 · · ·nk+1 with 1 ≤ ni ≤ Ni for i ∈ {1, . . . , k + 1} are there? Call Ak+1(N1, . . . , Nk+1) the quantity in question. Ford established the order of magnitude of A2(N1, N2) and the author of Ak+1(N, . . . , N) for all k ≥ 2. In the presen...
Contemporary debates on the rural sector in Latin America have led many to question the future viability of peasant livelihoods in the Andes. The paper first discusses certain limitations in these discussions of peasant viability. Firstly, they conflate agrarian with rural livelihoods, thus deflecting attention from the myriad transitions that have occurred in the ways through which people make...
The first epigenomes from archaic hominins (AH) and ancient anatomically modern humans (AMH) have recently been characterized, based, however, on a limited number of samples. The extent to which ancient genome-wide epigenetic landscapes can be reconstructed thus remains contentious. Here, we present epiPALEOMIX, an open-source and user-friendly pipeline that exploits post-mortem DNA degradation...
an in-time vision of literary works in their widespread spectrum is what always leads to the enrichment of literature and is also what helps transform it from a static state to a dynamic one. in the meantime, since the myths evolve and proceed with the passage of time and are always present in the course of history, they cannot be held an exception to this fact. the myths, among the different t...
The field of ancient DNA (aDNA) has rapidly accelerated in recent years as a result of new methods in next-generation sequencing, library preparation and targeted enrichment. Such research is restricted, however, by the highly variable DNA preservation within different tissues, especially when isolating ancient pathogens from human remains. Identifying positive candidate samples via quantitativ...
E ver since Vincent Knapp published his 1999 article ‘‘How old is Endometriosis?’’ (1), there seems to have been renewed interest in identifying just when endometriosis was discovered as a distinct disease entity. While the history of endometriosis subsequent to its 1860 microscopic unveiling by Karl von Rokitansky has been well-studied, its story leading up to that moment has remained largely ...
