Seeing properties of an invisible object: Feature inheritance and shine-through

We characterize a class of spatio-temporal illusions with two complementary properties. Firstly, if a vernier stimulus is flashed for a short time on a monitor and is followed immediately by a grating, the latter can express features of the vernier, such as its offset, its orientation, or its motion (feature inheritance). Yet the vernier stimulus itself remains perceptually invisible. Secondly, the vernier can be rendered visible by presenting gratings with a larger number of elements (shine-through). Under these conditions, subjects perceive two independent “objects” each carrying their own features. Transition between these two domains can be effected by subtle changes in the spatio-temporal layout of the grating. This should allow psychophysicists and electrophysiologists to investigate feature binding in a precise and quantitative manner.

Invisible Suffering: Practitioner Reflections on Peacebuilding Programs with Youth Exposed to Traumatic Stressors in Intergroup Conflict

For decades, the international community has recognized that youth are some of the most vulnerable to mental and emotional distress within the intractable and cyclical nature of identity-based violent conflict. Exposure to traumatic stressors within these intergroup conflicts poses unique risks not only to the neurological and social development of youth, but also to the capacities of youth to fully participate in peacebuilding interventions. The peacebuilding field has yet to strongly consider how traumatic stress affects dynamics within programs for youth and how these programs may need to modify expectations of youth’s cognitive, social, and emotional functioning to account for the traumatic dimensions of political and social violence. Through a qualitative analysis of practitioner reflections gathered from an online survey distributed worldwide, this study explores how practitioners conceptualize and approach issues of traumatic stress in peacebuilding programs focused on youth in conflict-affected contexts. The objective is to identify the working assumptions undergirding practitioner conceptualizations and approaches to traumatic stress and gaps in trauma interventions in peacebuilding programs for youth. The implications of these findings will support efforts to enhance trauma-sensitive peacebuilding practice by revisiting and reconsidering preexisting norms.

Invisible work, unseen hazards: the health of women immigrant household service workers in Spain

BACKGROUND: Household service work has been largely absent from occupational health studies. We examine the occupational hazards and health effects identified by immigrant women household service workers. METHODS: Exploratory, descriptive study of 46 documented and undocumented immigrant women in household services in Spain, using a phenomenological approach. Data were collected between September 2006 and May 2007 through focus groups and semi-structured individual interviews. Data were separated for analysis by documentation status and sorted using a mixed-generation process. In a second phase of analysis, data on psychosocial hazards were organized using the Copenhagen Psychosocial Questionnaire as a guide. RESULTS: Informants reported a number of environmental, ergonomic and psychosocial hazards and corresponding health effects. Psychosocial hazards were especially strongly present in data. Data on reported hazards were similar by documentation status and varied by several emerging categories: whether participants were primarily cleaners or carers and whether they lived in or outside of the homes of their employers. Documentation status was relevant in terms of empowerment and bargaining, but did not appear to influence work tasks or exposure to hazards directly. CONCLUSIONS: Female immigrant household service workers are exposed to a variety of health hazards that could be acted upon by improved legislation, enforcement, and preventive workplace measures, which are discussed.

The invisible hand... of the Kremlin. Capitalism 'a la russe'. OSW Point of View, February 2007

This study describes the two main economic processes observed in Russia during President Vladimir Putin's second term; renationalisation, and the concentration of economic assets. As a result of these processes, the share of state-owned property has increased and the position of the state in the economy has strengthened. According to the authorities, the wide-range renationalisation of the assets and the construction of superholdings based on the state enterprises are intended to boost Russia's potential and stimulate the development of the whole economy. However, in practice the current ruling elite are using these superholdings to strengthen Russia's position on the international arena and to promote their vested interests.
