The concept of social invisibility describes the devaluation of the perceived social and personal worth of an individual. This paper presents the theoretical foundation for this construct, and the development and validation of the "Invisibility Scale" capturing experiences of and needs for social (in)visibility within (i) intimate, (ii) legal, and (iii) communal relations. We developed and validated the Invisibility Scale in two studies.

Introduction: The proposed concept of secure/insecure lifeattachment reflects the experience of the world and life as a good (or insecure/threatening) place to be. The present article describes the theoretical foundation, development, and validation of a revised measure that captures the phenomenon of secure/insecure life attachment. The revised scale consists of seven dimensions: (1) Coexistence, (2) Reliability, (3) Safetiness, (4) Integration, (5) Inclusion, (6) Participation, and (7) Deliberation.

Self-control has been established as an important factor in various domains of life, significant for general well-being; thus, a self-induced lack of self-control may prove detrimental for well-being. Self-induced lack of self-control may stem from implicit beliefs about self-control as a limited resource, but research has shown this belief to be unwarranted. Furthermore, it has been shown that a belief about self-control resources as unlimited has a positive effect on many domains in life and ultimately on well-being.

The present study investigated the interplay among deficient life skills, moral disengagement, and extremist attitude across two national contexts. Using a sample of young students in high school or college (N = 686), the present study found significant indirect effects between deficient life skills (agency and structure) and various aspects of an extremist mindset through moral disengagement. These findings suggest that these two psychological concepts of life skills and moral disengagement are relevant for understanding and countering violent radicalization processes; that is to say that morality can direct the life skills toward either violent extremism or nonviolent, legal civil participation.

Violent radicalization has emerged as an important topic of theoretical and empirical investigation motivated by the devastating face of terrorism and by the aim of preventing such expressions of extremism. One central aspect of such research inquiries is the foundation of solid measurement. In this article, we develop and validate two generic scales pertaining to (1) endorsement of extremism and (2) acceptance of violent and/or illegal means.

The ubiquitous atmospheric dust on Mars is well mixed by periodic global dust storms, and such dust carries information about the environment in which it once formed and hence about the history of water on Mars. The Mars Exploration Rovers have permanent magnets to collect atmospheric dust for investigation by instruments on the rovers. Here we report results from Mössbauer spectroscopy and X-ray fluorescence of dust particles captured from the martian atmosphere by the magnets.
