Counterfactual de se

This paper addresses a long-standing debate concerning the derivation of de se construals. One camp holds that there is a dedicated mechanism of ‘de se binding’, which results in a de se pronoun being interpreted as a variable ranging over the doxastic alternatives of the attitude holder (e.g. Chierchia 1990). Another treats de se as a special case of de re under the acquaintance relation of identity (e.g. Lewis 1979, Reinhart 1990). This debate is premised on the assumption that the two different routes to de se result in identical truth conditions. I argue that this assumption is incorrect for a class of cases that can be delineated in a principled fashion — counterfactual attitude reports involving counter-identity, such as Ivanka imagined that she was Melania and she was giving an interview. The argument builds on Ninan 2008, who noticed that de re construal works differently with counterfactual attitudes, and that this has consequences for de se interpretation in this type of sentence. I spell out these consequences more precisely, drawing on a novel, crosslinguistically robust generalization about unambiguously de se expressions such as PRO (the ‘De Se Generalization’). I argue that a treatment of such expressions that appeals to de se-as-de re cannot account for the De Se Generalization in a principled way, and hence that a dedicated mechanism of de se binding must be included among the expressive resources of the grammar

Kearns-Sayre's syndrome developing in a boy who survived Pearson's syndrome caused by mitochondrial DNA deletion

Documenta Ophthalmologica 1992, Volume 82, Issue 1-2, pp 73-79 Kearns-Sayre's syndrome developing in a boy who survived Pearson's syndrome caused by mitochondrial DNA deletion Dr H. J. Simonsz, K. Bärlocher, A. Rötig … show all 3 hide » Download PDF (2,322 KB) Abstract A 7-year-old boy presented with bilateral ptosis and atypical retinitis pigmentosa. Before age two, he had had an Fe-refractory anemia, with neutropenia and thrombopenia. Just prior to the ophthalmic examination, the patient developed lactate acidosis, muscular hypotonia, ataxia and increased protein in the spinal fluid. Pancytopenia, pancreas dysfunction and growth retardation are the main features of Pearson's syndrome, most children not surviving beyond age three. The cause of Pearson's syndrome in our patient turned out to be a 5 kb deletion in the mitchondrial DNA. Similar deletions have been described in the Kearns-Sayre syndrome. It seems that children who survive the initial phase of Pearson's syndrome, may develop Kearns-Sayre syndrome

Thiopurine withdrawal during sustained clinical remission in inflammatory bowel disease: relapse and recapture rates, with predictive factors in 237 patients

Background: Thiopurines (azathioprine and mercaptopurine) remain integral to most medical strategies for maintaining remission in Crohn's disease (CD) and ulcerative colitis (UC). Indefinite use of these drugs is tempered by long-term risks. While clinical relapse is noted frequently following drug withdrawal, there are few published data on predictive factors. Aim: To investigate the success of planned thiopurine withdrawal in patients in sustained clinical remission to identify rates and predictors of relapse. Methods: This was a multicentre retrospective cohort study from 11 centres across the UK. Patients included had a definitive diagnosis of IBD, continuous thiopurine use ≥3 years and withdrawal when in sustained clinical remission. All patients had a minimum of 12 months follow-up post drug withdrawal. Primary and secondary end points were relapse at 12 and 24 months respectively. Results: 237 patients were included in the study (129 CD; 108 UC). Median duration of thiopurine use prior to withdrawal was 6.0 years (interquartile range 4.4–8.4). At follow-up, moderate/severe relapse was observed in 23% CD and 12% UC patients at 12 months, 39% CD and 26% UC at 24 months. Relapse rate at 12 months was significantly higher in CD than UC (P = 0.035). Elevated CRP at withdrawal was associated with higher relapse rates at 12 months for CD (P = 0.005), while an elevated white cell count was predictive at 12 months for UC (P = 0.007). Conclusion: Thiopurine withdrawal in the context of sustained remission is associated with a 1-year moderate-to-severe relapse rate of 23% in Crohn's disease and 12% in ulcerative colitis

On experience-driven semantic judgments: a case study on the Oneiric Reference Constraint

Using the interpretation of pronouns in dream and belief reports as a test case, we show that semantic judgments can vary as a function of experience. We present findings from three studies where semantic judgments for pronoun interpretations were affected by a) repeated exposure, or b) the experimental task which elicited the judgments. Our findings stress the importance of converging evidence from multiple tasks and paradigms when testing and formulating theoretical hypotheses

Moving from evidence-based medicine to evidence-based health.

While evidence-based medicine (EBM) has advanced medical practice, the health care system has been inconsistent in translating EBM into improvements in health. Disparities in health and health care play out through patients' limited ability to incorporate the advances of EBM into their daily lives. Assisting patients to self-manage their chronic conditions and paying attention to unhealthy community factors could be added to EBM to create a broader paradigm of evidence-based health. A perspective of evidence-based health may encourage physicians to consider their role in upstream efforts to combat socially patterned chronic disease

Refined saddle-point preconditioners for discretized Stokes problems

This paper is concerned with the implementation of efficient solution algorithms for elliptic problems with constraints. We establish theory which shows that including a simple scaling within well-established block diagonal preconditioners for Stokes problems can result in significantly faster convergence when applying the preconditioned MINRES method. The codes used in the numerical studies are available online

Thoracic Splenosis: A Case Report and the Importance of Clinical History

We present a case of thoracic splenosis in a 42-yr-old man with a medical history of abdominal surgery for a penetration injury with an iron bar of the left abdomen and back. He had been in good condition, but a chest radiograph taken during a regular checkup showed a multinodular left pleura-based mass. Computed tomography (CT) showed that the mass was well-enhanced and homogeneous, indicating a sclerosing hemangioma. Following its removal by video-assisted thoracoscopic surgery, the mass appeared similar to a hemangioma, with marked adhesion to the left side diaphragmatic pleura and lung parenchyma. Frozen section showed that the lesion was a solid mass consisted with abundant lymphoid cells, suggesting a low grade lymphoma. On permanent section, however, the mass was found to be composed of white pulp, red pulp, a thick capsule and trabeculae and was diagnosed as ectopic splenic tissue, or thoracic splenosis. Review of the patient's history and chest CT at admission revealed that the patient had undergone a splenectomy for the penetration injury 20 yr previously

Decision process in large-scale crisis management

International audienceThis paper deals with the decision-aiding process in large-scale crisis such as natural disasters. It consists in four phases: decision context characterization, system modelling, aggregation and integration. The elements of the context, such as crisis level, risk situation, decision-maker problem issue are defined through the characterization phase. At the feared event occurrence, these elements will interact on a target system. Through the model on this system, the consequences to stakes could be assessed or estimated. The presented aggregation approaches will allow taking the right decisions. The architecture of a Decision Support System is presented in the integration phase

Microfluidic systems for the analysis of the viscoelastic fluid flow phenomena in porous media

In this study, two microfluidic devices are proposed as simplified 1-D microfluidic analogues of a porous medium. The objectives are twofold: firstly to assess the usefulness of the microchannels to mimic the porous medium in a controlled and simplified manner, and secondly to obtain a better insight about the flow characteristics of viscoelastic fluids flowing through a packed bed. For these purposes, flow visualizations and pressure drop measurements are conducted with Newtonian and viscoelastic fluids. The 1-D microfluidic analogues of porous medium consisted of microchannels with a sequence of contractions/ expansions disposed in symmetric and asymmetric arrangements. The real porous medium is in reality, a complex combination of the two arrangements of particles simulated with the microchannels, which can be considered as limiting ideal configurations. The results show that both configurations are able to mimic well the pressure drop variation with flow rate for Newtonian fluids. However, due to the intrinsic differences in the deformation rate profiles associated with each microgeometry, the symmetric configuration is more suitable for studying the flow of viscoelastic fluids at low De values, while the asymmetric configuration provides better results at high De values. In this way, both microgeometries seem to be complementary and could be interesting tools to obtain a better insight about the flow of viscoelastic fluids through a porous medium. Such model systems could be very interesting to use in polymer-flood processes for enhanced oil recovery, for instance, as a tool for selecting the most suitable viscoelastic fluid to be used in a specific formation. The selection of the fluid properties of a detergent for cleaning oil contaminated soil, sand, and in general, any porous material, is another possible application
