Transoceanic America offers a new approach to American literature by emphasizing the material and conceptual interconnectedness of the Atlantic and Pacific worlds. These oceans were tied together economically, textually, and politically, through such genres as maritime travel writing, mathematical and navigational schoolbooks, and the relatively new genre of the novel. Especially during the age of revolutions in the late eighteenth and early nineteenth centuries, long-distance transoceanic travel required calculating and managing risk in the interest of profit. The result was the emergence of a newly suspenseful form of narrative that came to characterize capitalist investment, political revolution, and novelistic plot. The calculus of risk that drove this expectationist narrative also concealed violence against vulnerable bodies on ships and shorelines around the world. A transoceanic American literary and cultural history requires new non-linear narratives to tell the story of this global context and to recognize its often forgotten textual archive.

Purpose – The hyper-competitive environment clearly places a premium on innovation, entrepreneurship and adaptability. Less obvious is the premium that it also places on new approaches to identifying and managing risk and the hidden opportunities for value creation that lie therein. This masterclass aims to identify three books that show how risk management produces new opportunities for advantage. Design/methodology/approach – The masterclass discusses the approaches to risk management offered in The Risk-Driven Business Model by technology and innovation experts, Karan Girotra and Serguei Netessine; in Niraj Dawar’s book, Tilt: Shifting Your Strategy from Products to Customers and in The Alliance: Managing Talent in the Networked Age by Reid Hoffman, co-founder and chairman of LinkedIn, and his co-authors Ben Casnocha and Chris Yeh. Findings – Key choices you make in designing your business models will either increase or decrease two important types of risk, information risk and incentive-alignment risk. Downstream activities “aimed” at reducing customers’ costs and risks are rapidly emerging as the new “drivers” of value creation and competitiveness. Practical implications – The “central principle” underlying the new approach to talent risk management is “reciprocity” or mutual investment and obligation as a way of mitigating risk to both employer and employee […] The most innovative implementation practice is hiring employees for defined “tours of duty,” a concept borrowed from the military. Originality/value – This masterclass discusses three different approaches to managing risk and explains how they can be used to create customer value in a hyper-competitive environment.

Recent fishery failures, combined with changing views on management, point to the critical and urgent need for a new approach to fisheries management. Future management should focus on integrated fisheries, rather than solely on fish populations, and will require an appropriate combination of biological considerations with operational, social, and economic considerations of the fishery. This requires development of both a conceptual framework and an appropriate methodology for interdisciplinary decision making in fisheries management. We propose integration of the traditional fields of fisheries science and management with the scientific approach of management science to form Fisheries Management Science. Fisheries management science provides the framework and methodologies for defining multiple objectives and constraints, modelling alternative management scenarios, and assessing and managing risk. This framework accepts diverse information sources toward anticipatory decision making and consensus building, and offers a new paradigm within which effective fisheries management can emerge.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

Previously we reported that tannic acid is a very effective fixative for proteins including polypeptides. Especially, in the cross section of microtubules, thirteen submits in A-tubule and eleven in B-tubule could be observed very clearly. An elastic fiber could be demonstrated very clearly, as an electron opaque, homogeneous fiber. However, tannic acid did not penetrate into the deep portion of the tissue-block. So we tried Catechin. This shows almost the same chemical natures as that of proteins, as tannic acid. Moreover, we thought that catechin should have two active-reaction sites, one is phenol,and the other is catechole. Catechole site should react with osmium, to make Os- black. Phenol-site should react with peroxidase existing perhydroxide.

Immunoelectron microscopy of neoplastic lymphoma cells is valuable for precise localization of surface antigens and identification of cell types. We have developed a new approach in which the immunohistochemical staining can be evaluated prior to embedding for EM and desired area subsequently selected for ultrathin sectioning.A freshly prepared lymphoma cell suspension is spun onto polylysine hydrobromide- coated glass slides by cytocentrifugation and immediately fixed without air drying in polylysine paraformaldehyde (PLP) fixative. After rinsing in PBS, slides are stained by a 3-step immunoperoxidase method. Cell monolayer is then fixed in buffered 3% glutaraldehyde prior to DAB reaction. After the DAB reaction step, wet monolayers can be examined under LM for presence of brown reaction product and selected monolayers then processed by routine methods for EM and embedded with the Chien Re-embedding Mold. After the polymerization, the epoxy blocks are easily separated from the glass slides by heatingon a 100°C hot plate for 20 seconds.
