Torsion theories are here extended to categories equipped with an ideal of 'null morphisms', or equivalently a full subcategory of 'null objects'. Instances of this extension include closure operators viewed as generalised torsion theories in a 'category of pairs', and factorization systems viewed as torsion theories in a category of morphisms. The first point has essentially been treated in [15].

Although constructivism has many meanings and connotations in educational literature, I will examine this concept specifically from the perspective of my academic training (as a Developmental Psychologist) in this article. In addition to my academic background, I have reached a broader understanding of constructivism from my own teaching. Consequently, some of what I write represents extensions...

We test the theoretical prediction that profit sharing reduces worker separations and by doing so increases the incidence of training. Using individual level UK data, we confirm that profit sharing is a robust determinant of lower separation rates and of greater training incidence. Critically, we cannot confirm the predicted link between separations and training. Instead, the evidence supports ...

Psychoanalysts since Sigmund Freud have tried to discuss the role of religion in modern societies. Freud himself saw religion as an illusion which had struck neurotics, while Slavoj Žižek viewed it as some sort of “perversion” which functioned in the cycle of law-transgression. In this essay, I dig into these theories to uncover traces of Lutheran interpretations of Paul’s words on the Jewish l...

Old age is one of the most crucial stages of human development that encompasses the dynamics of biological processes, perception, growth and development and maturity, as a natural process of life. The elderly as one of the vulnerable groups, they face different biological, psychological and social needs. As the population gets older, the elderly will need more support in their daily activities,...

A number of navigational theories state that learning about landmark information should not interfere with learning about shape information provided by the boundary walls of an environment. A common test of such theories has been to assess whether landmark information will overshadow, or restrict, learning about shape information. Whilst a number of studies have shown that landmarks are not abl...

Research in sport pedagogy and its applied recommendations are still characterized by a contrast between the different learning theories from psychology. Traditional their corresponding approaches to specific case of teaching “how play [team sports like soccer]” subject compatibilities incompatibilities. We discuss how behaviorism as an approach game shows more incompatibilities with nature tac...
