Abstract Narratives and stories are important communication tools and as such essential subjects of social geography. This paper analyses the retelling of Greta Thunberg’s sailing trip across the Atlantic to the Climate Action Summit in New York in 2019 in leading German newspapers and magazines and how her intentions are transformed through this reporting into different narratives. The research mainly focuses on examining the influence of space and place, as geographical research has revealed that spatial determinants are crucial in risk communication and knowledge generation on climate change but have yet to be studied considering stories. The paper, therefore, extends the story-based approach from communication sciences by geographical research on the role of space and place in action-based stories. Therefore, the Narrative Policy Framework (NPF) is used to decode the spatial environment in narratives as an active element that shapes the narrative, and the way characters can (inter)act within these settings. The paper further develops the NPF framework through a geographical lens by focusing particularly on the selection options of spaces for social interactions and affective bonds. Thus, it becomes evident how spatial contexts and environments shape the interactions between individuals and crucially influence the types of narratives that emerge.

AbstractIntroduction and background??Arteriovenous malformations (AVMs) are congenital vascular lesions of the brain, which behave differently in pediatric population compared to adults. Treatment of pediatric AVMs includes a combination of microsurgery, embolization and radiation therapies. However, the role of radiosurgery in the treatment of pediatric AVMs is not fully accepted because of concerns regarding the long-term effects of radiation on the pediatric brain.Discussion??In this study, we review our experience at the University of Toronto with treating pediatric AVMs using linear accelerator-based (LINAC) radiosurgery over the past 15?years. We report our results, obliteration rates, and complications on a total of 40 patients. In addition, we provide a review of series published to date combined with our own results to determine whether radiosurgery is a safe and reasonable treatment modality for pediatric AVMs. [ABSTRACT FROM AUTHOR]

Patients and methods The clinical, radiological, surgical, and pathological findings of 16 children with a primary central nervous system (CNS) sarcoma are reported. There were 8 (50%) girls and 8 (50%) boys ranging in age from 4 months to 14 years (mean age 4.8 years). Four patients (23%) were in their 1st year of life. Fourteen children (87%) had an intracranial sarcoma, and 2 (13%) had intraspinal tumors. Nine intracranial tumors (60%) were supratentorial. The parietal and temporal regions were the most frequently involved sites. Results Characteristic imaging findings included tumor cysts in 7 patients and marked tumoral enhancement in 9 (69%) with intratumoral calcification and hemorrhage. All patients underwent at least one operation to surgically remove the tumor with the aim of maximal resection and 3 patients underwent a second resection due to a recurrent tumor. Resection was total in 9 (53%) patients and subtotal in another 7 (41%). Dural attachment by tumor was confirmed in 7 (44%) patients and parenchymal invasion was present in 9 (56%). In one-third of the patients there was a well-defined plane of dissection around the tumor. Postoperative radiation was used in 10 patients. Postoperative chemotherapy was used in all but 2 patients. Immunohistochemical studies were available in 13 patients with the most consistent finding being strong vimentin positivity. Five out of the 6 patients in whom the proliferation markers were obtained demonstrated a high proliferation index (Ki-67 labeling index, 20?50%). The mean length of survival in the group was 4.6 years (range 1 month to 16 years). Children who presented in the 1st year of life had shorter survival than those who presented at an older age. Six patients (40%) had cerebrospinal fluid (CSF) dissemination of the tumor. CSF dissemination was associated with a shorter mean survival of 1.9 years. Conclusions Our review of this series of patients indicates the requirement for adjuvant therapy and for continued efforts to classify tumor subtypes aimed at optimizing future treatments for patients with a primary CNS sarcoma.
