Organisations are regularly exposed to risk factors and issues that may be triggered by disruptive events that can impact on the organisation's performance and reputation. These disruptions can range from human error through to large-scale natural disasters and long-term global events that can reshape the complex landscape within which these organisations operate. Large-scale business actions, such as decentralisation, mergers and acquisitions, can also introduce major disruption to daily operations.

One of the challenges facing efforts to generate molecular biomarkers for toxins is distinguishing between markers that are indicative of exposure and markers that provide evidence of the effects of toxicity. Phenotypic anchoring provides an approach to help segregate markers into these categories based on some phenotypic index of toxicity. Here we leveraged the mussel embryo-larval toxicity assay in which toxicity is estimated by the fraction of larvae that exhibit an abnormal morphology, to isolate subsets of larvae that were abnormal and thus showed evidence of copper-toxicity, versus others that while exposed to copper exhibited normal morphology.

This paper discusses the challenges faced by organisations as disruptive events increasingly impact across operational, tactical and strategic operating levels. Organisations maintain the foundation of society by building the economy; they provide employment, wealth generation, material, services and community spirit. Simultaneously, they are being forced to diversify and innovate to maintain their share of global or local markets, thus inviting risk into the daily operating model.

Introduction: A 22-year-old female presented with a large abdominal mass that was revealed to be a primary retroperitoneal mucinous cystadenoma.

Presentation Of Case: A 22-year-old female presented with a two day history of bloating, mid-epigastric pain, and nausea without vomiting. A CT scan of her abdomen/pelvis showed a large left retroperitoneal mass, possibly a mesenteric cyst.

Background: The degree by which mechanisms underlying phenotypic convergence are similar among taxa depends on the number of evolutionary paths available for selection to act upon. Likelihood of convergence will be influenced by an interplay of factors such as genetic architecture, phylogenetic history and population demography. To determine if there is convergence or divergence in mechanisms underlying phenotypic similarity, we assessed whether gene transcription patterns differed among species with similar levels of hypoxia tolerance.
