Narrative Deliberation? On Storytelling as a Necessary Component of Public Deliberation

This paper deals with the place of narrative, that is, storytelling, in public deliberation. A distinction is made between weak and strong conceptions of narrative. According to the weak one, storytelling is but one rhetorical device among others with which social actors produce and convey meaning. In contrast, the strong conception holds that narrative is necessary to communicate, and argue, about topics such as the human experience of time, collective identities and the moral and ethical validity of values. The upshot of this idea is that storytelling should be a necessary component of any ideal of public deliberation. Contrary to recent work by deliberative theorists, who tend to adopt the weak conception of narrative, the author argues for embracing the strong one. The main contention of this article is that stories not only have a legitimate place in deliberation, but are even necessary to formulate certain arguments in the fi rst place; for instance, arguments drawing on historical experience. This claim, namely that narrative is constitutive of certain arguments, in the sense that, without it, said reasons cannot be articulated, is illustrated by deliberative theory’s own narrative underpinnings. Finally, certain possible objections against the strong conception of narrative are dispelled.

Quintus Curtius before his sources: the episode of Alexander and the Scythians on the Tanais

Quintus Curtius found in his sources a speech where a Scythian censured Alexander, followed by the King’s reply. Curtius drastically abridged this second discourse in order to highlight the criticism of the Macedonian. The Scythian’s words have a striking rhetorical language and some allusions taken from Greek literature, in addition to possible indirect references to Caligula. Curtius declares that he follows his source word-for-word aiming to justify these inconsistencies, but also trying to hide the manipulations he has done to achieve his own narrative purposes.

The value of military oath in civil wars in Rome: The example of conflict 49-45 BC

During the civil war between Caesar and Pompey, the military oath which binds the soldier to his army is often openly violated. Yet despite this offense, commanders of armed struggle require recursively the oath to their men. Admittedly, this ritual act seems ineffective given the many desertions and mutinies identified, but military leaders use its symbolic and sacred meaning to legitimize one hand their “anti-republican” actions, on the other armies fighting in a context deemed impius.

L'Idéologie politique des empereurs flaviens (69-96) à travers les sources épigraphiques et numismatiques

La dynastie des Flaviens est souvent mal connue et appréciée en raison de sa situation chronologique, « coincée » entre la famille des descendants de César et d’Auguste et celle allant de Trajan à Marc Aurèle. Elle passe parfois pour une simple dynastie de « transition » qui aurait uniquement servi de passerelle entre deux familles considérées comme plus brillantes qui ont par ailleurs laissé un souvenir plus durable. En un peu plus d’un quart de siècle (69-96), Vespasien, Titus et Domitien ont pourtant davantage fait pour la stabilité de Rome et de l’Empire que certains de leurs prédécesseurs ou successeurs. Sorti vainqueur des troubles civils de l’année des quatre empereurs (68-69), Vespasien ramena la paix en Orient et en Italie en plus de s’attacher à stabiliser les institutions et de reconstituer les finances de l’État, passablement écornées par les dernières années du Principat de Néron (54-68) et la guerre civile elle-même. Plus que la paix et la stabilité à l’intérieur et aux frontières de l’Empire, il fit cependant en sorte de refonder les bases institutionnelles du Principat en assumant sa transformation en un régime monarchique et héréditaire. Un principe parfaitement admis puisque ses deux fils adultes, Titus et Domitien, lui succédèrent sans difficulté. Davantage peut-être que les récits laissés par les sources littéraires anciennes, les inscriptions romaines et italiennes ainsi que les monnaies émises par l’atelier de Rome sont probablement le meilleur témoignage permettant de saisir le plus précisément et le plus profondément l’idée que les Flaviens se faisaient d’eux-mêmes et du pouvoir dont ils étaient investis. Le contenu de leur titulature officielle comme leurs choix iconographiques permettent ainsi de dégager leurs différents thèmes de propagande qui laissent finalement apparaitre une vraie continuité dans leur idéologie du pouvoir et leur manière de gouverner. Vespasien a ainsi posé des fondations idéologiques et politiques que ses fils ont globalement poursuivies et respectées, ce qui renforce l’idée selon laquelle les Flaviens ont effectivement suivi un « programme » qui les distinguait de leurs prédécesseurs et de leurs successeurs. Malgré des différences parfois importantes dans leurs pratiques, les inscriptions et l’iconographie monétaire permettent ainsi de mettre en lumière le fait que Titus et Domitien ont finalement moins cherché à faire preuve d’originalité qu’à s’inscrire dans la continuité de l’œuvre de leur père afin de garantir le maintien de la paix et avec elle la prospérité et la stabilité de l’État, et avec elles la satisfaction et la tranquillité de l’ensemble de la société.

The Performance Characteristics of a Surface-Modified Cutting Tool

In the past, many papers have been presented which show that the coating of cutting tools often yields decreased wear rates and reduced coefficients of friction. Although different theories are proposed, covering areas such as hardness theory, diffusion barrier theory, thermal barrier theory, and reduced friction theory, most have not dealt with the question of how and why the coating of tool substrates with hard materials such as Titanium Nitride (TiN), Titanium Carbide (TiC) and Aluminium Oxide (Al203) transforms the performance and life of cutting tools. This project discusses the complex interrelationship that encompasses the thermal barrier function and the relatively low sliding friction coefficient of TiN on an undulating tool surface, and presents the result of an investigation into the cutting characteristics and performance of EDMed surface-modified carbide cutting tool inserts. The tool inserts were coated with TiN by the physical vapour deposition (PVD) method. PVD coating is also known as Ion-plating which is the general term of the coating method in which the film is created by attracting ionized metal vapour in this the metal was Titanium and ionized gas onto negatively biased substrate surface. Coating by PVD was chosen because it is done at a temperature of not more than 5000C whereas chemical Vapour Deposition CVD process is done at very high temperature of about 8500C and in two stages of heating up the substrates. The high temperatures involved in CVD affects the strength of the (tool) substrates. In this study, comparative cutting tests using TiN-coated control specimens with no EDM surface structures and TiN-coated EDMed tools with a crater-like surface topography were carried out on mild steel grade EN-3. Various cutting speeds were investigated, up to an increase of 40% of the tool manufacturer’s recommended speed. Fifteen minutes of cutting were carried out for each insert at the speeds investigated. Conventional tool inserts normally have a tool life of approximately 15 minutes of cutting. After every five cuts (passes) microscopic pictures of the tool wear profiles were taken, in order to monitor the progressive wear on the rake face and on the flank of the insert. The power load was monitored for each cut taken using an on-board meter on the CNC machine to establish the amount of power needed for each stage of operation. The spindle drive for the machine is an 11 KW/hr motor. Results obtained confirmed the advantages of cutting at all speeds investigated using EDMed coated inserts, in terms of reduced tool wear and low power loads. Moreover, the surface finish on the workpiece was consistently better for the EDMed inserts. The thesis discusses the relevance of the finite element method in the analysis of metal cutting processes, so that metal machinists can design, manufacture and deliver goods (tools) to the market quickly and on time without going through the hassle of trial and error approach for new products. Improvements in manufacturing technologies require better knowledge of modelling metal cutting processes. Technically the use of computational models has a great value in reducing or even eliminating the number of experiments traditionally used for tool design, process selection, machinability evaluation, and chip breakage investigations. In this work, much interest in theoretical and experimental investigations of metal machining were given special attention. Finite element analysis (FEA) was given priority in this study to predict tool wear and coating deformations during machining. Particular attention was devoted to the complicated mechanisms usually associated with metal cutting, such as interfacial friction; heat generated due to friction and severe strain in the cutting region, and high strain rates. It is therefore concluded that Roughened contact surface comprising of peaks and valleys coated with hard materials (TiN) provide wear-resisting properties as the coatings get entrapped in the valleys and help reduce friction at chip-tool interface. The contributions to knowledge: a. Relates to a wear-resisting surface structure for application in contact surfaces and structures in metal cutting and forming tools with ability to give wear-resisting surface profile. b. Provide technique for designing tool with roughened surface comprising of peaks and valleys covered in conformal coating with a material such as TiN, TiC etc which is wear-resisting structure with surface roughness profile compose of valleys which entrap residual coating material during wear thereby enabling the entrapped coating material to give improved wear resistance. c. Provide knowledge for increased tool life through wear resistance, hardness and chemical stability at high temperatures because of reduced friction at the tool-chip and work-tool interfaces due to tool coating, which leads to reduced heat generation at the cutting zones. d. Establishes that Undulating surface topographies on cutting tips tend to hold coating materials longer in the valleys, thus giving enhanced protection to the tool and the tool can cut faster by 40% and last 60% longer than conventional tools on the markets today.

La inevitable inconsistencia del Zeus/Júpiter épico

Durante años la investigación literaria ha encontrado fruición en buscar y encontrar inconsistencias narrativas en la Tebaida de Estacio. Concretamente, hay cierto grado de consenso respecto a que las incongruencias en que incurre Júpiter son debidas a negligencia o incuria por parte del poeta. De hecho, no se puede negar que el soberano del cielo se contradice en las ocasiones en que alude a su relación con el Destino. No obstante, no será únicamente el poeta flavio el objeto de mi atención en este artículo. Hoy día se continúa acudiendo a la autoridad filosófica de Séneca (fundamentalmente a Dial. 1.5.8) siempre que el Zeus/Júpiter poshomérico (también el virgiliano) incurre en lo que hemos dado en considerar «incoherencias». Sin embargo, excepción hecha de las composiciones hesiódicas, el estatuto teológico de Zeus/Júpiter es altamente inestable en toda la tradición literaria griega y romana. Quizá deberíamos aceptar, entonces, que durante siglos los que estudiamos literatura antigua hemos tendido a prescindir de la voz autorial y de su autoridad omnímoda para manipular el material literario preexistente con el objeto de generar nuevos significados y nuevas cosmovisiones. En definitiva, nos hemos mostrado proclives a calificar de inconsistencias todo aquello que no se adecua a nuestras expectativas o prejuicios.

Lucrecio, "De rerum natura": Sentido y coherencia del prólogo

El prólogo del De rerum natura de Lucrecio (1.1-148) parece ser un tema gastado: ha sido tratado decenas de veces tanto por su excelente calidad como por los problemas que plantea. Pero esperamos poder dar un nuevo sentido y solución a ambos aspectos. En primer lugar, el himno a Venus no es una mera convención, sino que respira sentimiento religioso; Venus no personifica a la naturaleza, sino al placer y la felicidad y ni la hegemonía que se dice ejerce Venus, ni las plegarias que contiene el himno contradicen la teología epicúrea. Todavía más, nos parece que el himno constituye una auténtica epifanía religiosa muy propia de la teología epicúrea. En segundo lugar, suponiendo que el autor ha tomado como tema compartido los schemata o grados de dificultad de la intellectio retórica en el texto de 1.50-148, se intentan solucionar las dificultades de coherencia del texto.

Diet therapy with fodmaps restriction has benefits in fibromyalgia

The effects of a diet restriction in FODMAPs (Fermentable oligo-di-monosaccharides polyols) is being studied on the symptoms of Fibromyalgia (FM) and its impact on quality of life (QOL) besides the effect on gastrointestinal (GI) symptoms. High prevalence of functional GI disorders is found in FM and Low FODMAP Diet has growing scientific evidence as IBS (Irritable Bowel Syndrome) therapy.

A low fermentable oligo-di-mono saccharides and polyols (FODMAP) diet reduced pain and improved daily life in fibromyalgia patients

Fibromyalgia (FM) is a chronic, rheumatic disease characterized by widespread myofascial pain, of unknown aetiology, having a major impact on quality of life (QOL). Available pharmacotherapy for FM is marginally effective. FM is associated with co-morbidities of gastrointestinal (GI) disorders and Irritable Bowel Syndrome (IBS). There is growing evidence that diets low in FODMAPs, “fermentable oligo-, di- or mono-saccharides and polyols” [Low FODMAP Diet (LFD)], are effective in treating IBS. The aim of this pilot study was to examine the effects of LFDs on symptoms of FM, especially with regard to pain, QOL and GI disorders. Methods A longitudinal study using LFD intervention was performed on 38, 51 ± 10 year-old, female patients diagnosed with FM for an average of 10 years, based on ACR (American College of Rheumatology) 2010 criteria. The study was conducted from January through May, 2015, using a four-week, repeated-assessment model, as follows: Moment 0 – introduction of the protocol to participants; Moment 1 – first assessment and delivery of individual LFD dietary plans; Moment 2 – second assessment and reintroduction of FODMAPs; Moment 3 – last assessment and final nutritional counselling. Assessment tools used were the following: RFIQ (Revised Fibromyalgia Impact Questionnaire), FSQ (Fibromyalgia Survey Questionnaire), IBS-SSS (Severity Score System), EQ-5D (Euro-QOL quality of life instrument), and VAS (Visual Analogue Scale). Daily consumption of FODMAPs was quantified based on published food content analyses. Statistical analyses included ANOVA, non-parametric Friedman, t-student and Chi-square tests, using SPSS 22 software. Results The mean scores of the 38 participants at the beginning of the study were: FSQ (severity of FM, 0–31) – 22 ± 4.4; RFIQ (0–100) – 65 ± 17; IBS-SSS (0–500) – 275 ± 101; and EQ-5D (0–100) – 48 ± 19. Mean adherence to dietary regimens was 86%, confirmed by significant difference in FODMAP intakes (25 g/day vs. 2.5 g/day; p < 0.01). Comparisons between the three moments of assessment showed significant (p < 0.01) declines in scores in VAS, FSQ, and RFIQ scores, in all domains measured. An important improvement was observed with a reduction in the severity of GI symptoms, with 50% reduction in IBS scores to 138 ± 117, following LFD therapy. A significant correlation (r = 0.36; p < 0.05) was found between improvements in FM impact (declined scores) and gastrointestinal scores. There was also a significant correlation (r = 0.65; p < 0.01) between “satisfaction with improvement” after introduction of LFDs and “diet adherence”, with satisfaction of the diet achieving 77% among participants. A significant difference was observed between patients who improved as compared to those that did not improve (Chi-square χ2 = 6.16; p < .05), showing that the probability of improvement, depends on the severity of the RFIQ score. Conclusions Implementation of diet therapy involving FODMAP restrictions, in this cohort of FM patients, resulted in a significant reduction in GI disorders and FM symptoms, including pain scores. These results need to be extended in future larger studies on dietary therapy for treatment of FM. Implications According to current scientific knowledge, these are the first relevant results found in an intervention with LFD therapy in FM and must be reproduced looking for a future dietetic approach in FM.

Does an In-Season Detraining Period Affect the Shoulder Rotator Cuff Strength and Balance of Young Swimmers?

Aims: To compare the physical activity, sedentary activity and health-related quality of life (HRQoL) in institutionalized vs. non-institutionalized elderly, and to establish a pattern of relationship and prediction of physical and sedentary activity with physical and mental components of HRQoL. Methods: The sample consisted of 383 elderly with ≥ 75 years old (n=187 institutionalized and n=196 non-institutionalized). Were administered the International Physical Activity Questionnaire (IPAQ) and Short Form 36 Health Survey (SF-36) for evaluated the physical and sedentary activity and HRQoL. Also was used the Mini Mental State Examination (MMSE) as exclusion criteria for cognitive problems in the elderly. Results: Differences between institutionalized and non-institutionalized elderly were found in moderate-intensity activities and walking, a favour of non-institutionalized. The institutionalized elderly remain more minutes in sedentary activity. Also, were observed differences between both groups in physical component of HRQoL, a favour of non-institutionalized elderly. The mental component remained unchanged. The multivariate regression analyses showed that physical activity predicted the physical (8 to 12%) and mental (5 to 8%) components of HRQoL for institutionalized and non-institutionalized elderly. Conclusions: Non-institutionalized elderly were more physically active, spent less time in sedentary activity and showed better perception physical component of HRQoL that institutionalized elderly. An important and encouraging result of this study was that physical activity is a predictor of improved physical and mental component of HRQoL for institutionalized and non-institutionalized elderly.
