Several studies on the white sardine: Sardinella albella, have focused on the identification of stock composition and behavior. In this study population genetic structure and historical demography of S. albella along the cost of the Persian Gulf and Sea of Oman were investigated with a 500-bp segment of mt-DNA control region. In total 40 samples were collected from 3 locations: Jask in Sea of O...

The emerging field of corporate demography views corporations and industries in a similar way to human or animal individuals and groups. In spite of a surprisingly large overlap of subject matter with economics, corporate demography is not well-known by, nor easily accessible to economists. An outstanding recent book, The Demography of Corporations and Industries, by Glenn R. Carroll and Michae...

This paper describes steps taken towards introducing Web-based educational technology in teaching demography at the university level. Traditionally, demography is taught by giving lectures to the students, who are then expected to study from textbooks and exercise in demographic calculus. Some students find this way of learning monotonous and exhausting, hence their motivation gradually drops. ...

At a time when Portugal is struggling with budget deficits, public debt, unemployment, slow growth, and austerity – all issues causing a great deal of anxiety at home and much concern throughout the European Union (EU) and beyond – it might seem somewhat secondary to zero in on key features of the country’s demographic and health profile. But the reality is that these features are shaping, and ...

Piston aluminum alloys have different intermetallic phases, such as Cu3Al, Mg2Si ,and AlNi phases. The morphology and the distribution of such phases have important roles on mechanical properties of the piston material. Therefore, in this research, various ageing heat treatments on the mentioned material were done and the microstructural feature and the hardness were studi...

In recent years, the scientific interest of many demographers has shifted from studying “demographic regimes” and large-scale processes to analysing longitudinal micro data in the form of “life courses”. By some of its advocates, the “life course approach” is heralded as a new paradigm capable of reinvigorating the study of populations. Since, ultimately, demography deals with the fates and cho...
