History and Microhistories of Social Education in Spain

Social education in Spain has become increasingly popular in recent decades as both a socio-educational action/intervention and as a profession. The history of social education is a combination of various microhistories that have evolved within different areas. In order to understand the “micro” component of these histories, we need a perspective of the “macro,” while also keeping in mind that the microhistories are essential to understanding the true development of social education on a general level. The goals of this research are: to approximate the key historical antecedents that have influenced the development of social education in Spain as both a socio-educational action/intervention and a profession, to demonstrate the importance of analyzing the history of social education through microhistories, and to indicate the key elements and criteria necessary to carry out our microhistory of social education. Our methodology is the state of the field documentary research modality, which facilitated our study of the collective knowledge addressing a pedagogy of social education. This qualitative-documentary and critical-interpretive methodology followed these steps: contextualization, classification, and categorization. The main conclusion will indicate the definition of key points as well as the criteria necessary to be able to carry out a microhistory of social education.

Open Educational Resources in History: A State-of-the Field Essay

History practitioners are making steady progress adopting, adapting and creating open educational resources. However, most historians do not have a holistic view of the materials that exist in the open sphere due to poor discoverability and professional standards that still hamper their uptake. This state-of-the-field article discusses the challenges and opportunities of engaging with history OERs as divided into three categories: 1) textbooks and teaching modules, 2) informational websites and interactive experiences, and 3) digital tools for collaborative research. The flexibility and adaptability of these resources, afforded by their open licenses, are key points in their prospects for longevity and enduring benefit for the practice of history. The author concludes that, while more work remains to be done by administrators, librarians and pedagogy specialists around building awareness of open history, the digital revolution and changing attitudes towards collaborative scholarship lead to greater possibilities for this field.

Adaptive Radiation Therapy in the Treatment of Lung Cancer: An Overview of the Current State of the Field

Lung cancer treatment is constantly evolving due to technological advances in the delivery of radiation therapy. Adaptive radiation therapy (ART) allows for modification of a treatment plan with the goal of improving the dose distribution to the patient due to anatomic or physiologic deviations from the initial simulation. The implementation of ART for lung cancer is widely varied with limited consensus on who to adapt, when to adapt, how to adapt, and what the actual benefits of adaptation are. ART for lung cancer presents significant challenges due to the nature of the moving target, tumor shrinkage, and complex dose accumulation because of plan adaptation. This article presents an overview of the current state of the field in ART for lung cancer, specifically, probing topics of: patient selection for the greatest benefit from adaptation, models which predict who and when to adapt plans, best timing for plan adaptation, optimized workflows for implementing ART including alternatives to re-simulation, the best radiation techniques for ART including magnetic resonance guided treatment, algorithms and quality assurance, and challenges and techniques for dose reconstruction. To date, the clinical workflow burden of ART is one of the major reasons limiting its widespread acceptance. However, the growing body of evidence demonstrates overwhelming support for reduced toxicity while improving tumor dose coverage by adapting plans mid-treatment, but this is offset by the limited knowledge about tumor control. Progress made in predictive modeling of on-treatment tumor shrinkage and toxicity, optimizing the timing of adaptation of the plan during the course of treatment, creating optimal workflows to minimize staffing burden, and utilizing deformable image registration represent ways the field is moving toward a more uniform implementation of ART.
