Survey of infection control newsletters produced by Welsh infection control teams
Authors: Dawson S , Moseley L
Published: July 2017

The infection control team can provide education by a variety of methods. One cheap and effective method is by the use of newsletters. In our small survey only one department produced a newsletter, although almost half produced articles for a Trust publication. Maybe with the introduction of managed clinical networks into pathology, newsletters could be produced jointly by departments and distributed for use in several Trusts.
High Frequency Sealing of Polyolefin Structures
Authors: Davis Donna S. , Usher Lisa M.
Published: July 2017

This study investigated the potential of polyolefins for HF sealing. It included evaluation of comonomer type and level, additives (antiblock and slip), and thickness. Correlations were developed for seal strength versus dielectric properties, and the technique was compared with traditional hot-bar seal models.
'Phosphite-Free' Stabilization of Polyolefins
Authors: Young Sai S. , Laermer Stuart F. , Zambetti Peter F.
Published: July 2017

Deficiencies of present anti-oxidant (AO) systems led to our initiating a series of studies with 'phosphite-free' AO systems based on catocopherol (vitamin E) formulations. This study evaluated the effects of several AO systems on the yellowness index (YI), melt flow rate (MFR) and on gel formation after five to eight passes of two types of high density polyethylene (HDPE) and four types of polypropylene (PP) resins through an extruder. It was demonstrated that the a-tocopherol can replace phenolic/phosphite combination as the primary AO system; or the a-tocopherol formulations can simply replace the phosphite portion to achieve better performance. In either case, the problems associated with phosphites can be eliminated or minimized by the ca-tocopherol AO; and usually at a lower cost.
Re-Examining the Oxygen Barrier of Nylon 6 Films. I. Role of Moisture and Processing Induced Variables
Authors: Khanna Y. P. , Day E. D. , Tsai M. L. , Vaidyanathan G.
Published: July 2017

A common misconception over the years has been that the oxygen transmission rate (OTR) of nylon 6 increases as the relative humidity (RH) increases from 0 to 100%. Recent OTR measurements, however, have revealed that the OTR of nylon 6 exhibits a minimum at about 35% RH, i.e., maximum barrier. The improvement factor [OTRO%RH/OTR35%RH] depends on the type of nylon 6 film, e.g., 1.7X for cast film (AlliedSignal's Capran' film) and 2.7X for biaxially oriented film (AlliedSignal's Capran Emblem" film). In fact, there is no deterioration of OTR up to 65-80% RH, i.e., OTRO%RH OTR65%RH for cast films and OTRORH = OTR80%RH for biaxially oriented nylon 6 films. Prompted by this unexpected development, the role of morphological parameters in controlling the OTR of nylon 6, has been revisited. Infrared (IR) spectra reveal structural changes that can partly relate to the OTR vs% RH dependence. A neural network based approach has been used to model the OTR vs% RH curves in the 15-45% crystallinity range and make projections at low crystallinities (e.g., 0-15%) where direct OTR measurements would have been unreliable. Having known the effect of crystallinity on a quantitative basis, we have been able to demonstrate that the contribution of orientation (i.e., after correcting for induced crystallinity) to the OTR of nylon 6, is insignificant. Under otherwise similar physicochemical structural environment, processing history (i.e., shockcool) appears to have about 40% negative impact on the OTR of nylon 6. The highlight of this manuscript is that it quantifies the impact of moisture andprocessing related parameters on the OTR of nylon 6.

Finding an inherited complement abnormality in HSCT-associated TMA provides a rationale for the use of a complement inhibitor. Alternative complement inhibitors such as Coversin should be considered in patients who are resistant to eculizumab.
Assessment of body composition and the anthropometric parameters of the military personnel during high physical load exercises
Authors: Pļaviņa Liana , Vellere Natalija , Umbraško Silvija
Published: July 2017

Military activities are characterized with high physical endurance exercises and the psychological load. The cadets of the last study year participate in the combat training course lasting for ten days. The combat training course is a challenge for military officers. It is characterized with the transition from the daily military study process routine in the National Defence Academy to military exercises in the external environment. The cadets face feeding limitation, sleeping deprivation, intensive and continuous training, strict discipline, etc. Such a situation requires the adaptation to a novel way of activity, which includes hardships and arduous training. We provided the assessment of the body mass fluctuation during the combat training course. We provided the analysis of anthropometric parameters before, during and after the combat training course, summarized the data of the health statement and health problems that are fixed in the medical cards. The proper body mass supports the good health capacity. The body composition undergoes changes during the higher physical load performance. The analysis of the average value of the body mass and the Body Mass Index have shown large individual changes inside the groups. Physical fitness and body composition have an adverse effect on military performance. The assessment of the results of physical fitness tests is provided differentially according to the individual corresponding age subgroup. The military personnel have a high risk for the health concerning the impact of external and internal factors. According to the review of the medical cards of the cadets group we indicated the main problems which are fixed after the combat training course. These are acute respiratory infections, dermatological problems, locomotor system problems, gastro-intestinal problems.
Do height and weight play an important role in block and attack efficiency in high-level men's volleyball?
Authors: Stamm Raini , Stamm Meelis , Jairus Aleksander , Toop Reino , Tuula Reeda , João Paulo Vicente
Published: July 2017

The research objective was to study the relationships of players’ efficiency in attack and block with their anthropometric characteristics. Data on men’s weight and height and their proficiency in the game were used. The subjects were the members of the Estonian, Italian, French and Croatian national volleyball teams who participated in Pool B of the European Championship. Data are given on men’s height, weight, age, total number of spikes, attack errors, attacks won, efficiency of attack, total number of blocks, block errors, blocks won, and efficiency of block. In addition, the number of points won by men and their positions in the game are given. Minimums, maximums, standard deviations and means were calculated. To find correlations, Pearson’s correlation analysis (p<0.05) was used. In our study, taller and heavier players proved to be more efficient at attack. Comparison of positions showed that middle blockers were taller and performed more blocks, setters were shorter and performed the least of attacks, and outside attackers and opposite attackers were of medium height and carried the greatest load of attack. As a conclusion, it was found that, in professional volleyball, height correlated with the efficiency of attack (r= 0.534; p<0.05), and weight also correlated with the efficiency of attack (r= 0.518; p<0.05). There was no correlation between the anthropometric characteristics and block in volleyball at the professional level in our study. In volleyball, the greatest load at attack is carried by outside attackers and opposite attackers, while middle blockers have the greatest load at block. Setters perform the smallest number of attacks.

Since the age of 1 year, a child presented with hypoglycemic conditions accompanied by ketosis as well as periodic hyperglycemia, for which reason he was hospitalized to the Pediatric Endocrinology Department of the Mirotvortsev Saratov Clinical Hospital. At the hospital, the child underwent a comprehensive examination that excluded diseases such as hyperinsulinism and diabetes mellitus. In the Laboratory of Hereditary Diseases of Metabolism of the Medical Genetics Research Center, a hemizygotic mutation in the PHKA2 gene (glycogenosis type IX) was detected. The mother was also detected with the heterozygous mutation c.226G>A (p.E76K in the PHKA2 gene). Based on the results of the genetic examination of the child and mother, the patient was finally diagnosed with glycogenosis type IX. The patient was put on an individualized protein diet avoiding edible sugar and fatty foods; corn starch (30 g every 6 h and overnight) was recommended. Strict adherence to the diet resulted in less frequent seizures and decreased severity of episodes.

Published: July 2017

The results of molecular genetic studies indicate the potential involvement of ghrelin in the pathogenesis of some dwarfism forms. However, in the case of isolated somatotropin insufficiency, mutations in the ghrelin receptor gene are a rare cause of the disease. The article describes a case of identification, based on new generation sequencing (NGS) using the AmpliSeq technology, of a functionally significant marker ― the c.837C>A substitution in the ghrelin receptor gene GHSR (OMIM: 615925) in the heterozygous state in two sisters with isolated growth hormone deficiency and the clinical picture of malabsorption syndrome. We have supposed that mutations in the GHSR gene may be an etiological factor of isolated somatotropin insufficiency in a combination with malabsorption syndrome and eating disorders. Mutations in the GHSR gene enable predicting the development of somatotropin insufficiency not associated with abnormality of other pituitary hormones.
An unusual presentation of group A streptococcus infection in a newborn: with acute mastoiditis with no obvious clinical manifestation
Authors: Taheri Peymaneh Alizadeh , Jafari Mohsen , Mehrazmai Fouzieh
Published: July 2017

Acute mastoiditis (AM) is rarely seen in newborns. It is characterized by retroauricular pain, swelling, tenderness and protrusion of the auricle. This is the first report of the neonatal mastoiditis in a 17-day-old term neonate with no obvious clinical manifestation of mastoiditis and no associated malformation of the ears and mastoids. A computed tomography (CT) scan of the temporal bones revealed right mastoiditis without osteitis, destruction of the mastoid bone or abscess formation. Discharge culture revealed streptococcus A colonies sensitive to ampicillin, ceftriaxone, vancomycin and chloramphenicol. She was successfully treated with intravenous ampicillin and ceftizoxime. No complication or recurrence was reported.
Managerial capability for innovation for microfirms: integrating theory with empirical evidence
Authors: Kearney Arthur , Harrington Denis , Kelliher Felicity
Published: July 2017

The research considers a recently developed model of managerial capability for innovation in the microfirm context. Microfirms are firms employing less than 10 people. The research takes an interpretivist methodological approach based on a pilot study of five in-depth interviews with owner/managers of tourism microfirms. Findings indicate the incremental nature of innovation; the importance of aspects of managerial capability in the guise of leadership, operational capability, strategic thinking and the development of relationships with people. Innovation is shown to emerge through the interaction of aspects of managerial capability and key resource pools. The empirical research results in a refined model of managerial capability for innovation in context. A contribution to microfirm management practice is made through providing a model of managerial capability which can be used to improve the competitiveness of microfirms in the tourism industry. Allied to this contribution it is suggested that policy makers can use the model through further dissemination of their efforts to develop industry best practice. Recommendations for future empirical research based on an expanded microfirm study are suggested.
Das Wettbewerbsziel der deutschen Krankenhauspolitik – Eine ordnungsökonomische Einordnung
Authors: Dittmann Heidi
Published: July 2017

Der deutsche Krankenhaussektor weist eine hohe Regulierungsdichte auf. Standorte, Kapazitäten, Leistungsspektren, Fallzahlen und Preise sind nicht Ergebnis einer marktlichen Koordination von Angebot und Nachfrage, sondern eines staatlich-administrativen Planungsprozesses. Zugleich war die Einführung und Intensivierung des Wettbewerbs auf Märkten für Krankenhausdienstleistungen lange Zeit Gegenstand von Gesundheitsreformen. Seit der Einführung der DRG-Fallpauschalen wurde dieses Thema nicht wieder aufgegriffen. Aus ordnungsökonomischer Sicht lässt sich bisher jedoch kein Wettbewerb auf den deutschen Märkten für Krankenhausdienstleistungen erkennen. Als Erklärungsansatz für diese Diskrepanz wird das dem staatlichen Handeln zugrundeliegende Wettbewerbsleitbild diskutiert. Dieses entspricht nicht dem freien Koordinations- und Entdeckungsverfahren, das den Marktakteuren Handlungsfreiheit gewährt. Stattdessen soll wettbewerbliches Handeln innerhalb des planwirtschaftlichen Regulierungsrahmens erfolgen.
25 Jahre Fama-French-Modell: Erklärungsgehalt, Anomalien und praktische Implikationen
Authors: Kaserer Christoph , Hanauer Matthias X.
Published: July 2017

Eugene Fama und Kenneth French haben 1992 und 1993 ein erweitertes Modell zur Bewertung riskanter Finanztitel geschaffen. Dieses Fama-French-Modell ist gemeinsam mit dem Capital-asset-pricing-Modell (CAPM) zum Standardmodell der Kapitalmarktforschung geworden. Christoph Kaserer und Matthias Hanauer ziehen nach 25 Jahren ein Zwischenfazit. Dutzende von behaupteten Anomalien lassen weder dieses Modell noch die mit ihm eng verknüpfte Effizienzmarkthypothese in einem guten Licht erscheinen, doch dieser Eindruck trügt. Das Modell hat eine beachtliche Güte und Robustheit an den Tag gelegt. Es kann bis zu 90 Prozent der Renditevarianz erklären und hat sich, wenngleich mit Einschränkungen, auch außerhalb des amerikanischen Kapitalmarktes vielfach bestätigt. Auch neuere Wege zur Überprüfung des Modells führen zu einer Bestätigung dieser Befunde. Viele der behaupteten Anomalien sind hingegen weit weniger robust. Sie verschwinden, wenn man Transaktionskosten berücksichtigt, die statistischen Anforderungen an die heutigen Data-mining-Prozesse angleicht oder das Modell, wie Fama und French jüngst vorgeschlagen haben, in geeigneter Weise erweitert. Allerdings bleibt zumindest eine wesentliche Anomalie bestehen: der kurzfristige Momentum-Effekt. Er stellt die größte Herausforderung an das Modell und insbesondere an die Effizienzmarkthypothese dar. Die Autoren betrachten zudem die Bedeutung des Fama-French-Modells für die Praxis. In der Finanzmarktregulierung und in der Vermögensverwaltung beispielsweise hat es große Bedeutung, nicht aber in anderen Bereichen wie der Unternehmensfinanzierung und der Unternehmensbewertung.
Macrophage deficiency of miR‐21 promotes apoptosis, plaque necrosis, and vascular inflammation during atherogenesis

Atherosclerosis, the major cause of cardiovascular disease, is a chronic inflammatory disease characterized by the accumulation of lipids and inflammatory cells in the artery wall. Aberrant expression of microRNAs has been implicated in the pathophysiological processes underlying the progression of atherosclerosis. Here, we define the contribution of miR‐21 in hematopoietic cells during atherogenesis. Interestingly, we found that miR‐21 is the most abundant miRNAin macrophages and its absence results in accelerated atherosclerosis, plaque necrosis, and vascular inflammation. miR‐21 expression influences foam cell formation, sensitivity toER‐stress‐induced apoptosis, and phagocytic clearance capacity. Mechanistically, we discovered that the absence of miR‐21 in macrophages increases the expression of the miR‐21 target gene,MKK3, promoting the induction of p38‐CHOPandJNKsignaling. Both pathways enhance macrophage apoptosis and promote the post‐translational degradation ofABCG1, a transporter that regulates cholesterol efflux in macrophages. Altogether, these findings reveal a major role for hematopoietic miR‐21 in atherogenesis.
Petits commerces de bouche et réseaux alimentaires alternatifs: un regard montréalais
Authors: Maltais Alexandre
Published: July 2017

Cet article aborde les réseaux de distribution alimentaire alternatifs par une de leur leurs extrémités jusqu’ici négligée dans la littérature comme dans le débat public, les petits commerces de détail urbains. Ceux-ci se multiplient sur plusieurs rues commerçantes dans les grandes villes depuis quelques décennies, à la faveur d’un embourgeoisement de la population des quartiers limitrophes. Celle-ci entraîne une sophistication des préférences de consommation et favorise un repositionnement des petites entreprises commerciales vers des créneaux plus pointus, à l’abri d’une grande distribution en croissance. Sur la base d’une enquête de terrain de deux ans et d’une trentaine d’entrevues semi-directives réalisées auprès de propriétaires d’établissements commerciaux dont l’offre est entièrement ou partiellement composée de produits ou de services alimentaires, l’article examine les stratégies déployées par les commerçants pour se constituer comme alternatifs, les avantages d’un tel positionnement et les difficultés qui l’accompagnent. Producteurs et distributeurs alternatifs constituent ainsi deux maillons d’une chaîne qui ne peut donc être qualifiée d’alternative que tant qu’elle s’attache à se démarquer de l’univers de la consommation de masse.
Farm Stores in agriburbia: The roles of agricultural retail on the rural-urban fringe
Authors: Newman Lenore , Powell Lisa Jordan , Nickel Jennifer , Anderson Dylan , Jovanovic Lea , Mendez Eileen , Mitchell Barbara , Kelly-Freiberg Kathryn
Published: July 2017

This investigation highlights the role of on-farm stores on the rural/urban fringe near Vancouver, Canada. Operators achieve higher economic return by targeting populations interested in local food and in agritourism, including customers from towns in the fringe and from the larger nearby urban center. The farm stores catered to a rural idyll that reflects cultural conceptions of farm life. We suggest the multifunctional landscape of the farm store provides economic and cultural benefits, and should be considered as sustaining agriculture. The study revealed that farm store operators in particular share the rural idyll of urban consumers, though agritourism operators are more consciously including rural elements in their operations.

Botánica y topografía: el problema de la nivelación de las plantas en la historiografía científica sobre Francisco José de Caldas
Authors: Puerta Olaya María Alejandra , Escobar Ortiz Jorge Manuel
Published: July 2017

La nivelación de las plantas suele reconocerse como uno de los conceptos centrales del pensamiento y la obra de Francisco José de Caldas. Sobre él se han dado diversas interpretaciones, pero su abordaje suele hacerse de paso y sin indagar con mucho detalle acerca de sus presupuestos y consecuencias teóricas. En este artículo, identificamos diversas perspectivas que se han ofrecido con relación al origen, la función y la definición del concepto. Nos interesa así mostrar las dificultades que se presentan en la historiografía científica al abordar este concepto, y cómo estas dificultades generan inquietudes acerca de la coherencia que existe entre las diferentes interpretaciones sobre él. En particular, defendemos la tesis de que la lectura del término “nivelación de las plantas” se ha enfocado más sobre las plantas que sobre la nivelación, es decir, más sobre la botánica que sobre la topografía. Este presupuesto historiográfico ha llevado a construir narrativas históricas que, a pesar de la dimensión topográfica explícita del propio término, lo ubican en la historia de la botánica antes que en la historia de la topografía.

Making Sense of Alternative Assessment in a Qualitative Evaluation System
Authors: Rojas Serrano Javier
Published: July 2017

In a Colombian private English institution, a qualitative evaluation system has been incorporated. This type of evaluation poses challenges to students who have never been evaluated through a system that eliminates exams or quizzes and, as a consequence, these students have to start making sense of it. This study explores the way students face the new qualitative evaluation system and their views on alternative assessment as a way to help them make headway with their English learning process.
Rhetorical, Metacognitive, and Cognitive Strategies in Teacher Candidates’ Essay Writing
Authors: Díaz Larenas Claudio , Ramos Leiva Lucía , Ortiz Navarrete Mabel
Published: July 2017

This paper reports on a study about the rhetoric, metacognitive, and cognitive strategies pre-service teachers use before and after a process-based writing intervention when completing an argumentative essay. The data were collected through two think-aloud protocols while 21 Chilean English as a foreign language pre-service teachers completed an essay task. The findings show that strategies such as summarizing, reaffirming, and selecting ideas were only evidenced during the post intervention essay, without the use of communication and socio-affective strategies in either of the two essays. All in all, a process-based writing intervention does not only influence the number of times a strategy is used, but also the number of students who employs strategies when writing an essay—two key considerations for the devising of any writing program.
Motivating and Demotivating Factors for Students With Low Emotional Intelligence to Participate in Speaking Activities
Authors: Méndez López Mariza G. , Bautista Tun Moisés
Published: July 2017

The study aims to understand what factors may motivate and demotivate students with low emotional intelligence to participate in speaking activities during English class. Participants wrote an emotions journal to identify factors affecting student participation and were then interviewed at the end of the study period in order to elaborate on their experiences. Results showed that male participants experienced a wide range of negative emotions while females experienced a reduced number. However, in comparison, women experienced negative emotions frequently while men experienced them occasionally. Results also showed that males and females differed in the way that they perceived and faced situations, and in how they regulated the emotions generated by these situations.
Alfabetizando en geografía: medios y modos para educar la mirada de quienes comienzan en la comprensión de esta disciplina
Authors: Badillo Vargas Carolina Andrea , Crespo Allende Nina , Haas Prieto Valentina
Published: July 2017

En la etapa de escolarización, el estudiantado vivencia procesos de alfabetización múltiples (New London Group, 2000), debido a que cada disciplina llevada al currículo escolar posee formas especiales de construir conocimientos, a través de ciertos recursos, procedimientos y visiones de mundo, y formas de comunicarlos. Dicha construcción de significados situada es, entonces, particular según la comunidad disciplinar del profesor o profesora y su especialidad (Unsworth, 2001). Desde el enfoque de la semiótica social, el objetivo del presente estudio, enmarcado en el Proyecto Fondecyt 1130684, busca identificar cuáles son los medios y los modos semióticos con los que se alfabetiza en clases de geografía, para reconocer su potencial epistémico a través de las herramientas de la gramática visual (Kress y van Leeuwen, 1996). Este trabajo se basa en dos estudios de casos y el corpus está constituido por el registro audiovisual de unidades curriculares. Se realizó un inventario multimodal de los medios y los modos para comunicar (Kress, 2010) utilizados por dos profesores en la enseñanza de la geografía en primaria y secundaria en escuelas públicas en Chile. Los resultados muestran que el profesorado alfabetiza a través de distintos medios y modos, los cuales, en su mayoría, son visuales, algunos de ellos más complejos de comprender debido a la densidad y cantidad de símbolos a interpretar. Como resultado, el conocimiento en esta disciplina requiere ser aprendido y mediado de forma multimodal.
Equilibrios y tensiones en dos décadas de acreditación universitaria en Argentina: Aportes para un modelo conceptual
Authors: Marquina Mónica
Published: July 2017

Este artículo se propone realizar un balance de veinte años de experiencia de acreditación de carreras universitarias en Argentina desde la mirada de los actores involucrados: evaluadores, evaluados y responsables políticos y técnicos de los procesos de acreditación. Se parte del supuesto que la implementación de la política de evaluación y acreditación no constituyó un proceso lineal, gradual, ni simple, sino que implicó atender tensiones y contradicciones presentes en el accionar de los distintos actores implicados, y que pueden sintetizarse en tensiones presentes en cada uno de los ámbitos donde operan los actores, a partir de una tensión principal: la de la evaluación como acción fiscalizadora o de construcción de sentidos para el mejoramiento. Se trata, por tanto, de estudiar dichos procesos en toda su complejidad. El artículo enmarca el contexto y las características del sistema de evaluación y acreditación universitaria de Argentina, con foco en el funcionamiento de su agencia de evaluación: La Comisión Nacional de Evaluación y Acreditación Universitaria (CONEAU). Los resultados surgen del análisis de información proveniente de fuentes documentales, entrevistas en profundidad y una encuesta representativa a los sujetos que actuaron como evaluadores. En las conclusiones se propone un modelo conceptual representativo de “la arena evaluativa”, en el que se intenta graficar las tensiones y dinámicas de estos procesos complejos. El estudio se realiza desde una perspectiva de la evaluación como procesos políticos, participativos y de construcción de sentidos.

Pengaruh Penundaan Pengolahan terhadap Kandungan Histamin Ikan Lisong ( Scomber Australaskus Cv. )
Authors: Dwiyitno Dwiyitno , Subaryono Subaryono , Suryanti Suryanti
Published: July 2017

Penelitian ini dilakukan untuk melihat pengaruh penundaan pengolahan terhadap kandungan histamin ikan lisong (Scomber australasicus CV). Penundaan pengolahan dilakukan pada suhu kamar dan suhu rerdah (es). Pada suhu kamar, penundaan dilakukan selama 16 jam dengan pengamatan setiap 2 jam sekali, sedangkan penundaan pada suhu rendah menggunakan es di dalam coolbox selama 16 hari dengan pengamatan setiap 2 hari sekali. Parameter yang diamati meliputi kadar air, histamin, total volatile base (TVB) dan organoleptik. Hasil penelitian menunjukkan bahwa penundaan pada suhu kamar berpengaruh nyata terhadap peningkatan kandungan histamin, namun tidak demikian pada penundaan dengan es. Pada suhu kamar kadar histamin meningkat dari 75,7 mg/1 00 g menjadi 280,5 mg/1 00 g pada jam ke 16, sedangkan pada penundaan dengan es hanya meningkat menjadi 104,2 mg/100 g setelah hari ke‑10. Perlakuan penundaan pada suhu kamar maupun dengan es berpengaruh nyata terhadap nilai TVB ikan, yaitu pada suhu kamar TBV meningkat dari 26,4 mgN/100 g menjadi 54,3 mgN/100 g pada jam ke 16, sementara pada perlakuan dengan es menjadi 62,7 mgN/1 00 g pada hari ke 16. Pertumbuhan bakteri pembentuk histamin pada suhu kamar lebih cepat dibandingkan pada perlakuan dengan es. Pada awal penelitian jumlah bakteri 2,4 x 104 koloni/g dan meningkat menjadi 2,8 x 108 koloni/g pada perlakuan suhu kamar jam ke‑16, sedangkan pada perlakuan dengan es jumlah bakteri tertinggi pada hari ke‑8 yaitu 8,7 x 104 koloni/g. Pada suhu kamar ikan sudah ditolak oleh panelis pada jam ke‑12, sedangkan pada perlakuan dengan es pada hari ke­10,

De preterida a preferida: considerações em torno da trajetória intelectual de Alice Piffer Canabrava (1935-1951)
Authors: Erbereli Júnior Otávio
Published: July 2017

este artigo tem o objetivo de apresentar sinteticamente que a recuperação profissional da historiadora Alice Piffer Canabrava após a derrota no concurso para a cátedra de História da Civilização Americana, realizado em 1946, deveu-se a uma dupla conformação de fatores: a cultura acadêmica peculiar da Faculdade de Filosofia, Ciências e Letras da Universidade de São Paulo (FFCL-USP) em suas décadas iniciais e a arraigada concepção da época acerca do lugar da mulher na sociedade. Em contrapartida, seu ingresso e sucesso na Faculdade de Ciências Econômicas e Administrativas (FCEA) da mesma Universidade podem ser explicados pela cultura acadêmica distinta deste espaço. Para corroborar tal visão, também comparamos a trajetória de Alice Canabrava com a de outras mulheres que partilhavam de uma mesma ambientação institucional
Ramiz Galvão, historiador e bibliotecário: práticas e lugares da produção historiográfica no Brasil de fins do século XIX e início do século XX
Authors: Sampaio Caldeira Ana Paula , Mattos Clen Macedo Adriana
Published: July 2017

Este artigo parte das questões propostas por Michel de Certeau em seu texto “A operação historiográfica” para examinar a escrita da história no Brasil entre as décadas de 1870 e 1930. Um intelectual específico desse período, Benjamin Franklin Ramiz Galvão, nos servirá como fio condutor para essa análise. Embora não ocupe hoje lugar de destaque no panteão dos historiadores nacionais, Ramiz Galvão foi, em sua época, um intelectual-chave e uma referência pela sua atuação em diversas instituições de saber do Império e da República, como o Instituto Histórico e Geográfico Brasileiro e a Biblioteca Nacional. Analisando justamente a atuação desse agente nessas instituições, procuraremos ressaltar dois aspectos: em primeiro lugar, como a tarefa de compor um passado para a nação brasileira na virada do século XIX para o século XX envolvia diversas práticas, agentes e espaços; e, em segundo lugar, como sua figura é representativa de uma mudança nas regras do fazer historiográfico, mudanças essas que nos ajudam a compreender o próprio lugar que esse intelectual ocupa na memória disciplinar
Os limites entre a História e a Ficção
Authors: Geraissati Castro de Almeida Renata Castro
Published: July 2017

“O que fabrica o historiador quando ‘faz história’?”. Ao propor esta pergunta Certeau concluí que o historiador ao exercer seu ofício tem como resultado um produto, que tem imbricadas a presença de uma dimensão artística, que promove a ação do conteúdo sobre a forma, a consolidação da prática em um texto histórico.  Ao propor um papel criador na prática do historiador, associado com um método de pesquisa documental, o autor mostra a História como um misto entre ciência e arte. O objetivo deste artigo é, portanto, compreender como estes debates entre história e ficção foram utilizados na produção historiográfica. Inegavelmente houve uma contribuição no sentido de tornar a todos os historiadores conscientes da poética da história, contudo, o estatuto das fontes continua mantido, não se pode deixar de considerar que o documento deve continuar a desempenhar um papel fundamental no fazer historiográfico, e que todo historiador ao criar sua interpretação, deve estar comprometido com o “princípio de realidade”
Julgamentos a serviço da História
Authors: Menoncello Aline Michelini
Published: July 2017

Ao percorrer as atas da Revista Instituto Histórico e Geográfico Brasileiro (RIHGB) entre 1901 e 1921, analisei a participação de Pedro Augusto Carneiro Lessa (1859-1921), o ministro do Supremo Tribunal Federal. E deste modo interroguei-me: quem trabalha pela História no Instituto Histórico é o juiz Pedro Lessa ou o historiador Pedro Lessa? Tal pergunta será respondida a partir da problematização da categoria “autor” oferecida pelo filósofo francês Michel Foucault e pela análise dos textos assinados por Pedro Lessa: os pareceres emitidos para a Comissão de História, o estudo para o centenário de nascimento de Francisco Adolfo de Varnhagen e o Laudo Definitivo para decidir a data comemorativa da Confederação do Equador

A nostalgia como problema metahistórico: uma introdução
Authors: Freixo Andre De Lemos , Abreu Marcelo Santos de , Da Mata Sérgio
Published: July 2017

Os historiadores são em geral pouco interessados pelo fenômeno da nostalgia. Por vezes o termo “nostálgicos” é empregado no sentido de marcar os “conservadores”, num movimento complexo no qual tais conceitos são empregados de modo intercambiável. Os textos a seguir, por nós traduzidos, procuram convidar os historiadores brasileiros a prestar a devida atenção à abertura de possibilidades - não só teóricas, mas políticas - sugerida pela leitura dos ensaios de Arnold Gehlen - A felicidade evadida. Uma interpretação da nostalgia (1976) - e Svetlana Boym - A nostalgia e seus desgostos (2007).

ABSTRACT The aim of this study was to evaluate physicochemical characteristics, antioxidant activity, total phenolic, vitamin C and anthocyanins content of grape juices from cv. Isabel submitted to different UV-C doses. The fruits were harvested, sanitized and inserted into a UV-C radiation chamber, where different doses were applied: 0 kJ/m2 (0 minutes); 0.68 kJ/m2 (2 minutes); 2.73 kJ/m2 (4 minutes); 4.10 kJ/m2 (6 minutes). The grape juice was extracted at 75±5°C for 1 hour, using an equipment with steam extraction and submitted to evaluations after 0, 30, 60 and 90 days of cold storage. No significant differences were observed in grape juices submitted to radiation doses regarding the antioxidant activity and phenolic compounds. However, the vitamin C content was affected by different UV-C doses, where there was an increase in the values of the treated fruits during storage.
