Today there exist a wide variety of scientific workflow management systems, each designed to fulfill the needs of a certain scientific community. Unfortunately, once a workflow application has been designed in one particular system it becomes very hard to share it with users working with different systems. Portability of workflows and interoperability between current systems barely exists. In this work, we present the fine-grained interoperability solution proposed in the SHIWA European project that brings together four representative European workflow systems: ASKALON, MOTEUR, WS-PGRADE, and Triana. The proposed interoperability is realised at two levels of abstraction: abstract and concrete. At the abstract level, we propose a generic Interoperable Workflow Intermediate Representation (IWIR) that can be used as a common bridge for translating workflows between different languages independent of the underlying distributed computing infrastructure. At the concrete level, we propose a bundling technique that aggregates the abstract IWIR representation and concrete task representations to enable workflow instantiation, execution and scheduling. We illustrate case studies using two real-workflow applications designed in a native environment and then translated and executed by a foreign workflow system in a foreign distributed computing infrastructure.

Context.—The combination of testicular biopsy and clinical evaluation for male infertility is becoming progressively more important because new technologies allow men previously considered infertile to father children. Although most general pathologists are experienced with normal, neoplastic, and cryptorchid testicular specimens, the testicular biopsy for infertility requires understanding of a different set of diagnostic categories not otherwise commonly encountered. Objective.—To highlight a standardized nomenclature for germ cell abnormalities allowing for effective communication with the urologist and maximal clinical benefit from the biopsy. Data Sources.—Previously published consensus statements, review articles, peer-reviewed research publications, and abstracts. Conclusions.—A practical approach to evaluating testicular biopsies for fertility and the clinical implications for each abnormality are herein outlined.

This article provides a case study analysis of social reactions to the murder of Fusilier Lee Rigby in 2013. Informed by empirical data collected by systematic monitoring of social media platforms, the analysis identifies a number of online behaviours with offline effects-labeled the ten "Rs"-that collectively constitute the process of social reaction to the crime. These are defined as: reporting; requesting; responding; recruiting; "risking"; retaliating; rumouring; remembering; reheating; and "resiliencing". It is argued that the ability to observe these behaviours through the application of qualitative social media analysis has considerable potential. Conceptually, the analysis provides new insight into the complex and chaotic processes of sense-making and meaning attribution that arise in the aftermath of terrorist attacks. It illuminates how patterns of social reaction on social media are nuanced and complicated, with different segments of the public interpreting the same developments very differently. In addition, the findings and the conceptual framework outlined have implications for policy and practice development in terms of establishing a more effective and evidence-based approach to the consequence management of "post-event" conflict dynamics and social reactions.
