Lake sturgeon behavioural responses to <i>p</i>CO<sub>2</sub> and temperature
No full textBehavioural data for lake sturgeon reared in elevated pCO2, temperature, both, or neither and exposed to different cues. The file "Individual Mastersheet Feb 10 2020_MTadditions.xlsx" has data on time near a novel object, time in thigmotaxis zone, total activity, activity near a novel object, and activity in the thigmotaxis zone. The phrase MTadditions is from co-first author Matt Thorstensen filling in raw data from one treatment group from anonymized spreadsheets used by Luke Belding during scoring, which L. Belding was not able to do. The file "BoldnessTrial_1.MPG" has a representative video file of lake sturgeon behaviour in this experiment.The "Overwinter Data 2018 Master Sheet.xlsx" file has cue side and proportions of time in cue or facing cue following a 10,000 uatm pCO2 exposure. </p
History of Dialysis in the UK: c. 1950–1980
No full textDialysis, the first technological substitution for organ function, is significant not only for the numbers of patients who have benefited. It contributed to the emergence of the field of medical ethics and the development of the nurse specialist, and transformed the relationship between physicians and patients by allowing patients to control their treatment.
This seminar drew on participants’ recollections of dialysis from the early, practically experimental days after the Second World War, when resources for research were scant, until the 1980s when it had become an established treatment. Pioneers from the first UK dialysis units recalled the creation of the specialty of nephrology amid discouragement from renal physicians and the MRC, which felt that the artificial kidney was a gadget that would not last.
International and interdisciplinary collaborations, and interactions between with industry and clinics in developing and utilising the specialist technology were emphasized. Patients, carers, nurses, technicians and doctors reminisced about their experiences of home dialysis, its complications and impact on family life, as well as the physical effects of surviving on long-term dialysis before transplantation became routine.
The meeting was suggested and chaired by Dr John Turney and witnesses include Dr Rosemarie Baillod, Professor Christopher Blagg, Professor Stewart Cameron, Mr Eric Collins, Professor Robin Eady, Mrs Diana Garratt, Professor David Kerr, Professor Sir Netar Mallick, Dr Frank Marsh, Dr Jean Northover, Dr Chisholm Ogg, Dr Margaret Platts, Dr Stanley Rosen and Professor Stanley Shaldon. Two appendices contain reminiscences from Professor Kenneth Lowe and Sir Graham Bull
Injurious Effects from Contacts with Millipedes
No full textMillipedes are probably among the least mentioned of the so-called medically important arthropods. Perusal of a number of the more common texts dealing with the entomological aspects of medicine (Belding, 1942: 600, Craig and Faust, 1940:511, Herms, 1946: 539, Mackie, Hunter, and Worth, 1945:515) revealed the concept, which is commonly believed, that millipedes are not capable of producing injurious effects. A recent experience of the senior author and additional investigation by both writers have prompted the writing of this paper in an effort to broaden scientific thinking regarding the medical significance of this animal
The farmers' millennium: the ideology of agricultural improvement in Iowa, 1855 to 1865
No full textThe Morrill Act of 1862, a piece of federal legislation enacted a century and a half ago, lives on today. That law allocated thousands of acres of federal land to state governments, based on the size of their congressional delegations, so they could establish colleges of agriculture and the mechanic arts and give a college education, liberal and practical, to students who could not otherwise afford one. The Morrill Act lives on because the "land-grant colleges" it endowed with financial resources still exist today, operating on billion-dollar budgets and enrolling tens of thousands of students. Further, at least at Iowa State University, each incoming president's in-augural address has involved an explanation of the land-grant idea.
In the past three decades, that explanation has devolved from the broad view, held for a century, that land-grant colleges should prepare their students to be productive economically and politically, that they should educate them to be competent engineers and agriculturists as well as civic-minded people capable of acting not just in someone's private interest, but in their commu-nity's - their polity's - public interest. The latest presidents of Iowa State have, since the 1980s, put forward an explanation of the land-grant idea that places economic values, rather than politi-cal values, at the center of the university's existence. The work of historians of agriculture and the land-grant colleges has not been much better, the former paying little attention to the land-grant colleges and the latter more often than not failing to see the larger context in which the col-leges were created and have existed.
This thesis investigates the ideology that played a role in Iowa State University's creation in the late 1850s and early 1860s as the Iowa State Agricultural College and Model Farm. In the mid- to late 1850s, acting out of a concern for declining soil fertility (or the potential for it), the Iowa State Agricultural Society formulated an ideology of sustainable land use, scientific inves-tigation of farming techniques, and the equal dignity of labor (agricultural and mechanical work) with the more esteemed professions. The Society turned to a number of educational institutions, including annual fairs, agricultural periodicals, seed distribution programs by the federal govern-ment, township-level farmers' clubs, the state geological survey, and the state agricultural college, chartered in 1858, before the Morrill Act's passage. The author undertook this thesis because he believes that, if Iowa State's administration are going to invoke the history of the Morrill Act to rationalize their actions, they ought to know what that history is.</p
Detecting Traffic Conditions Model Based On Clustering Nodes Situations In VANET
No full textIn the last decade, cooperative vehicular network has been one of the most studied areas for developing the intelligent transportation systems (ITS). It is considered as an important approach to share the periodic traffic situations over vehicular ad hoc networks (VANETs) to improve efficiency and safety over the road. However, there are a number of issues in exchanging traffic data over high mobility of VANET, such as broadcast storms, hidden nodes and network instability.
This paper proposes a new model to detect the traffic conditions using clustering traffic situations that are gathered from the nodes (vehicles) in VANET. The model designs new principles of multi-level clustering to detect the traffic condition for road users. Our model (a) divides the situations of vehicles into clusters, (b) designs a set of metrics to get the correlations among vehicles and (c) detects the traffic condition in certain areas. These metrics are simulated using the network simulator environment (NS-3) to study the effectiveness of the model
Between Replication and Docking: "Adaptive Agents, Political Institutions, and Civic Traditions" Revisited
No full textThis article has two primary objectives: (i) to replicate an agent-based model of social interaction by Bhavnani (2003), in which the author explicitly specifies mechanisms underpinning Robert Putnam\'s (1993) work on Civic Traditions in Modern Italy, bridging the gap between the study\'s historical starting point—political regimes that characterized 14th Century Italy—and contemporary levels of social capital—reflected in a \'civic\' North and an \'un-civic\' South; and (ii) to extend the original analysis, using a landscape of Italy that accounts for population density. The replication exercise is performed by different authors using an entirely distinct ABM toolkit (PS-I) with its own rule set governing agent-interaction and cultural change. The extension, which more closely approximates a docking exercise, utilizes equal area cartograms otherwise known as density-equalizing maps (Gastner and Newman 2004) to resize the territory according to 1993 population estimates. Our results indicate that: (i) using the criterion of distributional equivalence, we experience mixed success in replicating the original model given our inability to restrict the selection of partners to \'eligible\' neighbors and limit the number of agent interactions in a timestep; (ii) increasing the number of agents and introducing more realistic population distributions in our extension of the replication model increases distributional equivalence; (iii) using the weaker criteria of relational alignment, both the replication model and its extension capture the basic relationship between institutional effectiveness and civic change, the effect of open boundaries, historical shocks, and path dependence; and (iv) that replication and docking may be usefully combined in model-to-model analysis, with an eye towards verification, reimplementation, and alignment.Replication, Docking, Agent-Based Model, Italy, Social Capital

Questions concerning the roles of premilitary, military and post military factors in Veteran’s vulnerability to homelessness have persisted despite the considerable attention given to Veteran homelessness, and has highlighted the absence of longitudinal studies that could contribute to the empirical understanding of risk and protective factors among this population. The Veterans in this study group completed Millennium Cohort Study surveys during their military service and subsequently, when they transitioned back to civilian life. Among these Veterans, 1,071 (2.2%) reported becoming homeless after separating from the military. Results from multivariate models provide limited empirical support for direct links between aspects of military service and homelessness that are widely used to explain why Veterans become homeless. Instead, many risk factors for homelessness found here mirror risk factors among the general population. We also find a persistent association between sexual orientation and risk for homelessness, and decreased risk for homelessness among female Veterans. These findings challenge popular conceptions of why Veterans become homeless and contribute to understanding the dynamics of becoming homeless among this current Veteran cohort.S.M. acknowledges institutional support from the National Center for Homelessness Among Veterans at the US Department of Veterans Affairs.

Phylogenetic lineages in the Capnodiales
No full textThe Capnodiales incorporates plant and human pathogens, endophytes, saprobes and epiphytes, with a wide range of nutritional modes. Several species are lichenised, or occur as parasites on fungi, or animals. The aim of the present study was to use DNA sequence data of the nuclear ribosomal small and large subunit RNA genes to test the monophyly of the Capnodiales, and resolve families within the order. We designed primers to allow the amplification and sequencing of almost the complete nuclear ribosomal small and large subunit RNA genes. Other than the Capnodiaceae (sooty moulds), and the Davidiellaceae, which contains saprobes and plant pathogens, the order presently incorporates families of major plant pathological importance such as the Mycosphaerellaceae, Teratosphaeriaceae and Schizothyriaceae. The Piedraiaceae was not supported, but resolves in the Teratosphaeriaceae. The Dissoconiaceae is introduced as a new family to accommodate Dissoconium and Ramichloridium. Lichenisation, as well as the ability to be saprobic or plant pathogenic evolved more than once in several families, though the taxa in the upper clades of the tree lead us to conclude that the strictly plant pathogenic, nectrotrophic families evolved from saprobic ancestors (Capnodiaceae), which is the more primitive stat
