El historiador-científico y/ o el historiador-escritor: límites y transgresiones de la tarea cognitivo-literaria de escribir la historia

La pregunta acerca del estatus epistémico de la narración histórica ha sido formulada de manera tal que el espectro de respuestas posibles se reduce al delimitado por una alternativa excluyente; o bien la narración histórica es valorada positivamente como un discurso "científico", o bien es menospreciada como una rama de la literatura. En este contexto, pensar en apelar a la teoría literaria como recurso relevante para elaborar una teoría de la historia genera desconfianza, dado que se asume que tal asociación no puede sino redundar en una mirada debilitadora de la tarea del historiador

El concepto de campo histórico como construcción lingüístico-ficcional-hipotética en Hayden White

Nuestro articulo, en primer lugar, remontará el afán crítico de White hacia una de sus fuentes teóricas; el estructuralismo. En segundo lugar, reconstruirá los aspectos más positivos de la perspectiva whiteana ligados a la postulación del concepto de "campo histórico" como central para entender la dinámica epistémica de la obra histórica. Finalmente, destacaremos cómo en el concepto de "ficción" o ''ficcionalización" puede evidenciarse esta doble mirada crítico-positiva del autor. Deberemos recordar que White presenta una teoría que se propone explicar cómo comprendemos el pasado, a partir del modo en que los historiadores ofrecen explicaciones históricas en forma de textos

The effects of verbal information on children's fear beliefs about social situations

Two experiments explored the role of verbal information in changing children’s fearrelated beliefs about social situations. In Experiment 1, 118 6- to 8- and 12- to 13-year-olds heard positive, negative, or no information about individuals’ experiences of three social situations. Fear beliefs regarding each situation were assessed before and after this manipulation. Verbal information had no significant influence on children’s fear beliefs. In Experiment 2, the same paradigm was used with 80 12- to 13-year-olds, but the information took the form of multiple attitude statements about the situations expressed by groups of peers, older children, or adults. An affective priming task of implicit attitudes was used to complement the explicit questions about fear beliefs. Negative information influenced both explicit and implicit fear beliefs. The source of information and the child’s own social anxiety did not moderate these effects. Implications for our understanding of the socialisation of childhood fears are discussed

Prime testimonianze letterarie su Paestum nel XV e XVI secolo: Pontano, Alberti, Leto ed altri

Lo studio prende in esame alcuni brani letterari già noti del Cinquecento su Paestum (Summonte, Lettieri, Maffei, Leandro Alberti, Mazzella), per poi ritrovare l'origine di alcune affermazioni già in autori del Quattrocento, di età aragonese, che avevano con tutta probabilità visitato personalmente Paestum, ma finora non segnalati: Pomponio Leto, Leon Battista Alberti, Giovanni Pontano, Gabriele Altilio, Giovanni Albino, Pietro Ranzano, Antonio de Ferraris Galateo

Bioimpedenziometria e valutazione dell'efficienza fisica nella sorveglianza nutrizionale in età evolutiva

BIOELECTRICAL IMPEDANCE ANALYSIS AND PHYSICAL FITNESS IN ASSESSING THE NUTRITIONAL STATUS OF CHILDREN AND ADOLESCENTS ABSTRACT Background The evaluation of body composition and the assessment of physical fitness are both relevant issues in public health nutrition. In children/adolescents different aspects of body composition may be related to growth, health and well being, including in-creased body fat content and/or abdominal fat as well as a decreases fat-free mass, appendicular muscle mass and/or body cell mass. Bioelectrical impedance analysis (BIA) is a field method providing estimates of FFM by means of predictive equations which include BIA variables and frequently other variables such as age and weight. As an alternative, the use of directly-measured raw BIA variables, such as impedance ratio (IR) or phase angle (PhA) has gained attention, because these latter are thought to be related to body cell mass, ex-tracellular/intracellular water ratio and cell health. Health related physical fitness is an important component of overall health in the first two decades of life being associated with cardiovascular risk factors, bone health, ac-ademic performance, etc. It can be evaluted by using a number of tests assessing dif-ferent aspects of physical fitness such a muscolar strenght and endurance, flexibility, and cardiorespiratory endurance. To date there is a scarcity of data available in the literature regarding raw BIA varia-bles in the first two decades of life, as well as the relationships between physical fit-ness tests and body composition. Aim The aim of the Thesis was to evaluate: 1) the changes of raw BIA variables with time and their differences due to the gen-eral characteristics of the individual; 2) the relationships of physical fitness test with general characteristics of the individ-ual, BIA-derived estimates of body composition, and BIA variables; 3) changes in 1) and 2) due to overweight/obesity. Subjects In this thesis the evaluation of body composition and physical fitness was carried out in 1) general population sample: children and adolescents (n=396) recruited in two schools (Studies 1-2); 2) obese sample: overweight and obese children and adoles-cents (n=277) recruited from a outpatient clinic for obesity (Study 3). Methods Standard procedures were used for collecting data on the following variables: 1) stature, weight, waist circumference; 2) BIA: impedance (Z) at 5-10-50-100-250 kHz and phase angle at 50 kHz for both dominant and non-dominant body sides (whole body, upper limbs, and lower limbs); 3) Physical fitness tests: handgrip strength, standing long jump, five-long jump, chair (sit-to-stand), six-minute walk test (6MWT); 4) derived variables: BI index as stature²/Z, impedance ratios (IRs) as ratios between Z at higher frequencies (5,10 and 50 kHz) and Z at lower frequencies (5 and 10 kHz). Results Study 1: Consistent data on changes in BIA raw variables were obtained over the age span 6-13in the general population sample and systematically presented for either the whole body or upper and lower limbs. An increase in BI indexes and phase angle with age was apparent, while IRs declined progressively. Significant differences in BIA raw variables were observed between males and females, with some dissimilari-ties when upper and lower limbs were compared to each other. Study 2: We identified several determinants of fitness-related tests in the subjects. In addition to gender and age, BIA-derived FFM, BI index, IRs and phase angle were all significant predictors of handgrip strenght, and less consistently of standing long jump and standing five jumps. IR and phase angle were also predictors of the 6MWT, but not of the chair test. Study 3: Phase angle did not differ significantly between genders in over-weight/obese children and adolescents, but still remain a significant predictor, con-currently with the BI index, of HGS, standing long jump and standing five jumps. Weight and BMI-SDS were weak predictors of the 6MWT. Conclusion The results presented in the Thesis increase to a considerable extent the information available on row BIA data in children and adolescents, first of all with regard to changes with time and between-gender differences. Raw BIA variables (BI indexes, IRs and phase angle) emerged as significant predictors of physical fitness tests in normal-weight, but also in overweight/obese children and adolescents, the stronger relationship being the one with HGS

Globalizing Hayden White

This conversation originated in a plenary session organized by Ewa Domańska and María Inés La Greca under the same title of ‘Globalizing Hayden White’ at the III International Network for Theory of History Conference ‘Place and Displacement: The Spacing of History’ held at Södertörn University, Stockholm, in August 2018. In order to pay homage to Hayden White’s life work 5 months after his passing we knew that what was needed–and what he himself would have wanted–was a vibrant intellectual exchange. Our ‘celebration by discussion’ contains elaborated and revised versions of the presentations by scholars from China (Xin Chen), Latin America (María Inés La Greca, Veronica Tozzi Thompson), United States (Paul Roth), Western (Kalle Pihlainen) and East-Central Europe (Ewa Domańska). We took this opportunity of gathering scholars who represent different parts of the world, different cultures and approaches to reflect on White’s ideas in a global context. Our interest was in discussing how his work has been read and used (or even misread and misused) and how it has influenced theoretical discussions in different parts of the globe. Rather than just offering an account as experts, we mainly wanted to reflect on the current state of our field and the ways that White’s inheritance might and should be carried forward in the future.Fil: Domanska, Ewa.

Rose nate sui rovi: ricerche sulle antiche rose di Paestum

Il saggio prende in esame alcune fonti tardoantiche sulle rose di Paestum, in particolare Ennodio, il quale loda l'attività operosa dei pestani che fa nascere rose dalle spine. Questa immagine è stata sempre interpretata come letteraria e metaforica. L'analisi dettagliata dei brani e del loro contesto fa tuttavia intendere che le rose pestane erano effettivamente prodotte a partire da innesti su piante spinose delle rosacee, rovi o biancospini. A questa ipotesi ha fatto seguito un esperimento di innesto della rosa sul rovo, "rubus fruticosus", che ha prodotto una rosa grande, centifolia, con molti petali. La ricerca e l'esperimento, oltre a mettere in luce le antiche tecniche di coltivazione, possono contribuire alla odierna valorizzazione dell'area pestana
