We model a labor market in which workers' level of education might be a signal of skills. We show that whenever the wage premium for education increases over time – as it might happen under skill biased technological progress – the investment in education needed to sustain a separating equilibrium in which skilled workers perfectly signal their type, also increases. Hence, an increase in the ed...

Catalytic behavior of isomorphously substituted B-, Al-, Ga-, and Fe-containing extra-large pore UTL zeolites was investigated in Knoevenagel condensation involving aldehydes, Pechmann condensation of 1-naphthol with ethylacetoacetate, and Prins reaction of β-pinene with formaldehyde and compared with large-pore aluminosilicate zeolite beta and representative Metal-Organic-Frameworks Cu3(BTC)2 ...

Some studies find that democratic states are more amenable to third party forms of conflict management, while other studies indicate that democracies are able to resolve contentious issues on their own through bilateral negotiations. Using data from the Issue Correlates of War (ICOW) Project, the authors investigate peaceful and militarized conflict management strategies that democratic states ...

Background. A number of commentators (Holloway 1996 Muijen 1996a; 1996b) have suggested that two events in the form of homicides carried out by mental health service users came to exert a disproportionate influence on English mental health policy over the period 1985-2000. In particular it has been suggested that the events formed the focus for a ‘moral panic’ caused by ‘irresponsible’ and ‘sen...

In mammals, Robertsonian (Rb) translocation (the joining of two telo/acrocentric chromosomes at their centromere to form a metacentric) is the most effective process in chromosomal evolution leading to speciation; its occurrence also affects human health (through the induction of trisomies) and the fertility of farm animals. To understand the mechanism of Rb translocation, we used the house mou...

Analysis of the origin of domestic animals is of wide interest and has many practical applications in areas such as agriculture and evolutionary biology. Identification of an ancestor and comparison with the domesticated form allows for an analysis of genetic, physiological, morphological and behavioral effects of domestication. Because fox breeding has been an ongoing process for over a centur...

Low copy repeats (LCRs) located in 22q11.2, especially LCR-B, are susceptible to rearrangements associated with several relatively common constitutional disorders. These include DiGeorge syndrome, Velocardiofacial syndrome, Cat-eye syndrome and recurrent translocations of 22q11 including the constitutional t(11;22) and t(17;22). The presence of palindromic AT-rich repeats (PATRRs) within LCR-B ...

Male infertility is caused by many factors including genetics. Although part of genetic damages are inherited and could be traced in blood leukocytes, but those de novo alterations induced in spermatogenesis are not part of diagnostic work up. De novo alterations might be the cause of many idiopathic conditions of male infertility. The aim of this study was to evaluate DNA damage, sex chromosom...
