It is an ecological network with a unique natural and cultural heritage, an emotional human and political history, meaning and transformative power. Due to the former border situation, it is a transnational green infrastructure with biodiversity hotspots in a more and more fragmented, intensively used and degraded European landscape and connects people from 24 European countries and valuable landscapes. But now, nearly 30 years after the peaceful transition in 1989, the gaps in the European Green Belt cover already 50%. These gaps are not protected and are subject to adverse effects, like ongoing landscape fragmentation and ongoing chemo-industrial agriculture. Alarming signals of a new death zone are not only the gaps within the European Green Belt, but generally and closely related the mass extinction of species, climate change, resource depletion, financial and economic crisis, demographic change, emigration, unemployment and/or precarious work worldwide. To save the European Green Belt and life on earth there is a great need ofa 2^nd transformation to a life-sustaining world.展开更多

New groups of writers and new writing styles are constantly springing up and existing theoretical criticism has been attacked and torn apart, with the result that it has often lost its voice. With the rapid growth of online literature, the influence of non-mainstream literature in the domain of literary reading and consumption is increasing. Consequently, the above-mentioned problem is evolving into a new contradiction, i.e. a lack of mutual understanding and tolerance with regard to reading. In the past decade, an enormous number of novels have come out online, falling into over twenty categories. This paper takes into account both chronology and type of writing in selecting for review ten outstanding works of different genres from the last decade, stressing the aesthetic qualities and distinctive styles that differentiate them from their print counterparts.展开更多

Yet, parents often feel under-prepared and alone, their experiences inadequately known to healthcare professionals. The research aim was to examine the meaning to parents of caring for a child with an eating disorder. Qualitative interviews with 29 parents were analyzed and the parents’ experiences were represented by a collective story of loving her into well-being one day at a time which consisted of two themes: Running on nerves and caring through transformational activism. Running on nerves included threads of feeling lost, traumatized, scarred, and disengaged that mitigated as parents engaged in transformational activism processes directed toward helping themselves, their child, and other parents and children. The findings illustrate the importance of hearing parents’ stories in order to create supportive healing environments and to build capacity within families and health care systems.展开更多
