Published: May 2019

ABSTRACT The definition of experimental plot size is an essential tool to ensure precision in statistical analysis in experiments. The objective of this study was to estimate the plot size for the cactus pear cv. Gigante using the Modified Maximum Curvature Method, under the semi-arid conditions of Northeastern Brazil. The uniformity test was conducted at the Federal Institute of Bahia, Guanambi Campus, Bahia state, Brazil, during the agricultural period from 2009 to 2011. The spatial arrangement was composed of ten rows with 50 plants each, whose evaluated area was formed by the eight central rows with 48 plants per row, making 384 plants and area of 153.60 m2. The following variables were evaluated: plant height; length, width and thickness of cladode; number of cladodes; total area of cladodes; cladode area and green mass yield in the third production cycle. In the evaluations, each plant was considered as a basic experimental unit (BEU), with an area of 0.4 m2, comprising 384 basic units (BU), whose adjacent ones were combined to form 15 pre-established plot sizes with rectangular shapes and in rows. The characteristics total area of cladodes and green mass yield require larger plot sizes to be evaluated with greater experimental accuracy. For experimental evaluation of cactus pear cv. Gigante, plot size should be eight plants in the direction of the crop row.

Published: May 2019

ABSTRACT Hydroponic cultivation using saline waters is an alternative for agricultural production, especially in the cultivation of vegetables. Therefore, the present work was conducted with the objective of evaluating the water consumption, water use efficiency and water content, as well as dry matter partitioning of chives (Allium schoenoprasum), cv. Todo Ano Evergreen – Nebuka exposed to six levels of nutrient solution salinity (1.5, 3.0, 4.5, 6.0, 7.5 and 9.0 dS m-1), applied at two circulation frequencies (twice a day at 8 and 16 h; and three times a day - at 8, 12 and 16 h). The level in the nutrient solution reservoir, which decreased according to the water consumption by plants, was replaced with the respective saline water (Experiment I) and supply water (Experiment II). Both experiments used a completely randomized design, in a 6 x 2 factorial scheme, with five replicates. It was observed that increased circulation frequency and the use of supply water in the replacement mitigated the effects of salinity on water consumption, water use efficiency and water content in the plant. However, with the increase in nutrient solution electrical conductivity, dry matter allocation in the roots increased, to the detriment of the shoots.

ABSTRACT This study had the following objectives: to identify and quantify the constituent compounds of essential oils from Cymbopogon winterianus Jowitt, Eucalyptus globulus Labill., Eucalyptus staigeriana F. Muell. ex F.M. Bailey, Foeniculum vulgare Mill., Ocimum basilicum L., Ocimum gratissimum L., and Piper hispidinervum C. DC., investigate their toxicity and repellency to S. zeamais and evaluate the toxicity of P. hispidinervum to immature S. zeamais. Individual tests for each essential oil were conducted with a completely randomized design with five concentrations for each oil and four replicates. Gas chromatography-mass spectrometry revealed the presence of citronellal in C. winterianus, 1,8-cineole in E. globulus, limonene in E. staigeriana, limonene in F. vulgare, linalool in O. basilicum, (E)-anethole in O. gratissimum, and safrole in P. hispidinervum. The median lethal concentration required to kill 50% of the insect (LC50) in contact and ingestion toxicity tests ranged from 5.12 to 78.89 μL 40g-1 corn in P. hispidinervum and C. winterianus, respectively. In adult fumigation tests, the LC50 ranged from 2.1 to 19.4 µL L-1 air, and in immature fumigation tests, the egg stage was susceptible to essential oil, whereas larval and pupal phases were tolerant. All of the oils repelled S. zeamais.

Published: May 2019

ABSTRACT The search for statistical techniques and forms of graphical representation that can explain the most relevant correlations among limnological variables can help interpret phenomena in a body of water. The objective of the article was to propose a graphical representation of the correlations among limnological variables applied in the contributing basin of the Dr. João Penido reservoir, in Juiz de Fora, Minas Gerais state, Brazil. Six sections were monitored monthly from May 2012 to April 2014, analysing 15 water quality parameters and their statistical correlations. The correlations were represented graphically with the program Gephi 0.8.2-beta. The influence of organic matter (of natural and anthropogenic origin resulting from pasture runoff and sewage) on water quality was verified, with an observed increase in water quality parameters especially nitrogen and phosphorous, oxygen consumed, chemical oxygen demand, turbidity and total suspended solids. It is concluded that the correlation chart assists in the understanding of the dynamics of the water quality parameters at the different sites analysed.
Automobile insurance in Brazil: market concentration and demand
Authors: Peres Vivileine Maria , Maldonado Wilfredo L. , Candido Osvaldo
Published: May 2019

ABSTRACT This paper studies two aspects of the automobile insurance market in Brazil: first, it determines the degree of competition among insurance companies, and second, it estimates and analyzes the demand for automobile insurance. Most of the studies on the automobile insurance market in Brazil analyze the performance of the firms in this sector or present regional studies of the demand for insurance and its determinants. Thus, this study innovates both in showing the competition among the firms and estimating the demand for insurance in the country. The relevance of this research lies in the sequential and ordered way it analyzes the demand in a sector. Firstly, it identifies the type of competition that takes place in the sector and then, based on this, it proposes a structural framework based on optimizing decisions for estimating the price, income, and market power elasticities of demand. Furthermore, analyzing the insurance industry is of the utmost importance since it moves significant amounts of financial resources and provides an essential service in the economy. With information about the market structure and demand profile in the automobile insurance sector it is possible to propose strategic policies for individual firms as well as for the whole sector in order to introduce more efficiency. To analyze the degree of competitiveness, several concentration indices were calculated using annually-aggregated monthly data on the premium paid to all the automobile insurance firms in the period from 2001 to 2016. To estimate the demand for automobile insurance, half-yearly data from 2002 to 2010 for each one of the 27 federative units of Brazil were used. Two main findings are presented in this study. First, we find evidence of little concentration in the Brazilian automobile insurance market, with shares being well distributed among the players. Second, we estimate the demand for automobile insurance in Brazil and find a price-elasticity of -0.47 in the short run and -1.33 in the long run, while the lagged profitability has a negative impact on the amount insured: -0.21 in the short run and -0.59 in the long run. Income does not significantly influence the demand for insurance in Brazil.

RESUMO O presente estudo visa descrever os benefícios da inserção do fisioterapeuta sobre o perfil de prematuros de baixo risco internados em unidade de terapia intensiva neonatal. Estudo caso-controle, retrospectivo, com consulta aos prontuários de prematuros internados em 2006/2007 sem fisioterapia (PREF) e em 2009/2010 com fisioterapia por até 8h/dia (POSF). Incluíram-se 61 prematuros no período PREF e 93 no POSF, nascidos com ≥1000g, SNAP-PE II <40, com tempo de suporte ventilatório ≥24h. Verificou-se os perfis materno e dos neonatos, tempos de internação, de ventilação mecânica invasiva e não invasiva e de oxigenoterapia. Realizou-se análise descritiva, teste Mann Whitney, teste t, qui-quadrado e Fisher, considerando-se p≤0,05. Houve diferença significativa entre as idades gestacionais [PREF: 230,5 (±16,5)/ POSF: 226 (±15); p=0,05], frequência de sepse [PREF: 6 (10%)/ POSF: 30 (32%); p<0,01], de síndrome do desconforto respiratório [PREF: 11(18%)/ POSF: 43 (46%); p<0,01], necessidade de reanimação na sala de parto [PREF: 10 (16%)/ POSF: 32 (34%); p=0,02], necessidade de intubação orotraqueal [PREF: 8 (13%)/ POSF: 26 (28%); p=0,05], tempo de ventilação não invasiva (PREF: 0,1±0,4 dias/ POSF: 0,8±2,3 dias; p<0,01), de ventilação invasiva (PREF: 0,4±1,3 dias/ POSF: 1,3±3,3 dias; p=0,04), de pressão positiva contínua em vias aéreas (PREF: 1,5±1,0 dias/ POSF: 2,7±3,8 dias; p=0,04). A presença do fisioterapeuta gerou benefícios, contribuindo para a manutenção dos tempos de internação e de oxigenoterapia mesmo diante de um perfil de recém-nascidos mais imaturos e com mais intercorrências no período após a inserção da fisioterapia.
Do polyembryonic seeds of Carapa surinamensis (Meliaceae) have advantages for seedling development?
Authors: FERREIRA Débora Najara de SOUZA , CAMARGO José Luís Campana , FERRAZ Isolde Dorothea Kossmann
Published: May 2019

ABSTRACT Polyembryony is the differentiation and development of multiple embryos in a single seed. This characteristic can provide advantages, as more than one embryo is produced with the same amount of resources, and the probability of establishment of at least one seedling increases. However, sibling seedlings may also increase competition, affecting development and survival. In the present study, the possible advantages and disadvantages of polyembryony were analyzed in the initial establishment of seedlings of Carapa surinamensis (Meliaceae), a tree species that produces monoembryonic or polyembryonic seeds. In this regard, the development of single seedlings was compared with a pair of seedlings emerging from polyembryonic seeds. We compared the development of seedlings attached to or detached from each other and to the seed resources. We observed two levels of competition: (a) for the seed reserves during germination and initial development, as multiple embryos of C. surinamensis share the same reserves, and (b) for external factors, mostly space for root and shoot development, and also for light. Reducing the competition for external factors by separating the siblings was not enough to reduce the effects of competition for seed reserves in the first six months of development. Nevertheless, viable seedlings were produced in all treatments. Thus, depending on sprout management in the nursery, the number of seedlings per seed can be significantly increased by detaching the seedlings, or more vigorous seedlings can be obtained when only one seedling is maintained.
Reproductive and feeding biology of the common lancehead Bothrops atrox (Serpentes, Viperidae) from central and southwestern Brazilian Amazonia
Authors: BISNETO Pedro Ferreira , KAEFER Igor Luis
Published: May 2019

ABSTRACT The pitviper Bothrops atrox is a widely distributed and medically important snake in Amazonia. Given that the reproductive and feeding biology of snakes varies geographically, we aimed to characterize the natural history of individuals from the central and southwestern portions of the biome. We analyzed museum-preserved specimens collected in the region between the metropolitan areas of the Brazilian cities of Manaus and Porto Velho. We took morphometric measurements and performed the analysis of gonads and digestive tracts of 109 individuals. Females attain sexual maturity with larger body sizes. Adults of the species show pronounced sexual dimorphism in body size, with females being larger. The reproductive cycle, especially in males, appears to be synchronized with regional rainfall, which markedly differed across the biome. The pitvipers had a generalist diet, consuming a wide range of prey such as centipedes, frogs, lizards, snakes and mammals. We provide the first record of predation of the snake Imantodes cenchoa (Dipsadidae) by B. atrox. There was an ontogenetic shift in the diet: smaller individuals fed mainly on ectothermic prey (centipedes, frogs, lizards and snakes), while adults tended to incorporate endothermic prey (mammals) to their food repertoire.

ABSTRACT Objective: to understand the care actions developed for the relatives of users of psychoactive substances from the perspective of professionals and family members. Method: based on the Social Phenomenology approach of Alfred Schütz’s. The research was performed in a Psychosocial Alcohol and Drug Attention Center of a municipality in the State of Rio Grande do Sul, Brazil. Phenomenological interviews were conducted with 13 professionals and 12 family members of users of psychoactive substances, from July to November, 2016. The steps suggested by Social Phenomenology researchers were used for data analysis. Results: three categories were revealed: care actions for family members from the perspective of professionals; care actions identified by family members, and reciprocity of perspectives in relation to care actions for family members. The professionals reported care actions developed in the service for the family: listening, reception, individual care, guidance, referrals, family groups and home visits; and care actions identified by family members: family group, care, reception, resolution, psychological support and guidance. The reciprocity of perspectives in relation to care actions for family members, from the perspective of the professionals and family members was: a group of family members, reception and guidance. Conclusion: the findings provide support to professionals to review their health care actions, based on the expectations of care mentioned by family members as well the contribution to comprehensive and resolute mental health care, especially in out-of-hospital care.
CUIDADO CLÍNICO E SOBREMEDICALIZAÇÃO NA ATENÇÃO PRIMÁRIA À SAÚDE
Authors: Tesser Charles Dalcanale
Published: May 2019

Resumo Este ensaio analisa a sobremedicalização (medicalização desnecessária e indesejável) gerada no cuidado médico aos adoecidos na atenção primária à saúde, discute como ocorre e como evitá-la. Articula na análise três grupos de concepções/saberes: concepções de doença (dinâmicas/ontológicas); concepções de causação (ascendente/multidirecional); eixos conceituais estruturantes do saber médico (anatomopatológico, fisiopatológico, semiológico, epidemiológico). A sobremedicalização deriva dos movimentos cognitivos dos profissionais na elaboração diagnóstica e terapêutica. Ela nasce da associação da concepção ontológica de doença com causação ascendente (fluxo causal que vai dos elementos materiais mais simples a dimensões e níveis mais complexos), em articulação com sobrevalorização do eixo anatomopatológico, geradora de excessivas intervenções diagnósticas e farmacoterapêuticas. Para evitar a sobremedicalização, propomos a associação virtuosa da concepção dinâmica de doença, com causação multidirecional e uso equilibrado dos eixos conceituais das doenças. Isso facilita: escuta qualificada; contextualização dos casos; mais criterioso uso de exames complementares; reconhecimento dos limites diagnósticos biomédicos; superação da razão metonímica (que despreza tudo o que não é saber cientificamente consagrado); amplificação da interpretação para além das 'doenças' e dos tratamentos para além dos fármacos/cirurgias, explorando os saberes dos usuários e profissionais, práticas complementares e a devolução de problemas para o manejo autônomo apoiado.

Resumo Este artigo teve por objetivo evidenciar e analisar as mudanças relativas às expectativas do tornar-se médico ao longo da graduação em medicina. Fizeram parte da pesquisa, realizada entre abril e junho de 2018, estudantes de medicina matriculados na primeira, quinta, oitava e décima segunda fases de uma instituição pública de Ensino Superior de Santa Catarina. Após aplicação de questionário, foram analisadas 145 respostas à seguinte pergunta: Por que você escolheu cursar medicina? Por meio de análise de conteúdo, evidenciou a presença crescente, no decorrer do curso, por aquilo que denominamos de 'retorno financeiro' e, de maneira inversa, o decrescente interesse por 'ajudar ao próximo'. Os resultados, analisados com base em teorias que abordam os processos de socialização e de formação identitária mostraram que, apesar de inseridos em realidades socioculturais distintas, os indivíduos se encontram envoltos por ritos e estereótipos comuns, socialmente convencionados por padrões social e historicamente construídos pelo processo de constituição da identidade médica.

Published: May 2019

ABSTRACT Gummy smile is one of the major complaints of patients, due to its influence on the self-esteem. It is known that it has a multifactorial cause and can be present in the excessive vertical growth of the maxilla, excessive labial contraction, short upper lip and extrusion of the anterior teeth. The use of the botulinum toxin can be associated with additional treatments or be applied individually, according to the need of each patient. The goal of this research study was to present a clinical case using botulinum toxin type A as an alternative therapy to correct the gummy smile. A 22-year-old patient, presenting vertical maxillary growth, reporting aesthetic discomfort while smiling, chose for an alternative treatment therapy with the application of botulinum toxin to correct the accentuated gingival display. The results show that the toxin is a satisfactory treatment option and its indication is considered a fast, effective, easy and safe treatment method, being a more conservative approach compared to surgical procedures.

ABSTRACT Mucocele is a term applied to the clinical manifestation of phenomena that may affect the minor salivary glands. There are different forms of treatment reported in the literature, including total enucleation. The objective of this study is to describe a surgical technique for removal of Mucocele in a teenage patient. A 16-years-old, female, attended the sector of Pediatric Dentistry of Camilo Castelo Branco University - campus São Paulo / SP. The patient’s main complaint was “a bubble in the mouth that punchs and fills again, feeling salty taste.” At the clinical examination, a circumscribed, mucosa-like, floating-palpation lesion was observed, with a 1.7 cm diameter in the lower lip, with characteristics similar to Mucocele. In the planning of the case, we opted for the surgical removal treatment with anatomopathological analysis. The prognosis for the surgical removal of the lesion was very favorable due to some established criteria: age of the patient, location, depth and size of the lesion.

ABSTRACT Objective: This study aimed to investigate the correlation between FT and anxiety. Methods: The sample consisted of 95 participants categorized into two groups: a) G-FT, 48 patients with FT and b) CG, 47 healthy participants. All patients were submitted to complete oral and dermatological examinations. The anxiety levels were measured using the State-Trait Anxiety Inventory (STAI). A p-value of < 0.05 was considered significant. Results: Fourteen (30%) patients reported awareness of having FT and 9 (64%) were women. Symptoms like burning feeling were reported by 3 (6%) only patients, all of then women. None of the control group patients presented these symptoms. In both groups, control and FT, the average scores of trait-anxiety were slightly higher than state-anxiety. There were no statistically significant differences between the FT and the control group related to the state-anxiety (p=0.724) and the trait-anxiety (p=0.680) scores. Study limitations: This study was limited by the number of subjects. Conclusion: Although moderate state-anxiety and trait-anxiety scores were determined, anxiety, as an environmental factor may not play a significant role in the development of FT. Considering FT as a multifactorial disease, probably a genetic component is necessary for expression.

ABSTRACT The aim of this article is to describe a surgical technique of option in the treatment of large tumors in jaw whose risk of accidental rupture of the mental nerve presents increased by the report of a patient with mandibular giant case of odontoma. The option for intraoral access, intentional sectioning of the mentonian nerve, followed by resection of the tumor and the installation of fixation material, which in turn was followed by microneurorraphy. A surgical microscope was used to perform microneurorrhaphy of the mentonian nerve with Nylon 8-0 wire. The evolution of the patient was satisfactory, with no complaints or complications. A mechanical assessment for torque and pressure was conducted using wire with a diameter of 1.0mm and 2.5mm, respectively. The sensitivity of the patient’s lower lip returned to normal within 120 days of the surgery. Significant enucleations or resections in the mandible involves a great risk of accidental nervous rupture, with permanent sequelae. In these cases, the intentional section of the mentonian nerve, followed by microneurorrhaphy, is a viable option, particularly in young patients. The results of this procedure tend to be more predictable than accidental nervous ruptures.

Published: May 2019

Abstract Research indicates that trauma (sexual, physical, and emotional abuse) is a factor commonly present in the life of marital abusers. This study aimed to investigate the life history characteristics and personality of men who perpetrated violence against women and were detained in the Central Prison of Porto Alegre, Brazil. We also identified sociodemographic characteristics, the presence of psychopathological symptoms and understood the intrapsychic dynamics involved in the participants’ marital choice, as well as their perception regarding the experience of detention. Three participants filled out a personal data sheet, answered the Rorschach method, the MINI Interview, and participated in three semi-structured interviews. The interviews were examined from the interpretative analysis technique based on psychoanalytic theory. The results allow us to understand the violence committed by the participants as a result from a life story marked by traumatic experiences that produced narcissistic flaws and the expression of aggressiveness.
Influence of Density and Development Stage of Ryegrass on Glyphosate Effectiveness
Authors: FIPKE M.V. , VIDAL R.A.
Published: May 2019

ABSTRACT : Glyphosate is one of the main herbicides used to control ryegrass. The objective of this research was to evaluated whether the glyphosate dose-response curve is affected by density of ryegrass plants in two phenological growth stages. To attend this objective, two experiments were carried out in greenhouse (one with Lolium multiflorum and another with Lolium rigidum) and two under field conditions. In the greenhouse experiments, the experimental design was a completely randomized design in a factorial scheme, with factor A as plant density and factor B as glyphosate doses. In the field, two experiments were carried out in a randomized block design in a split-plot scheme. Plots consisted of glyphosate doses (0, 40, 80, 120, 160, 250, and 350 g ha-1), and the subplots consisted of three ryegrass densities (8 plants m-2, 140 plants m-2 with thinning before herbicide application, and 140 plants m-2 with thinning after herbicide application). In one experiment, glyphosate was sprayed at 28 days after emergence (DAE), whereas in another the application was carried out at 51 DAE. High-density ryegrass plants required a higher herbicide dose to obtain the same level of control of low-density plants. In addition to the density effect, an increased glyphosate dose was necessary for the late application to obtain the same level of control when compared to the initial application. Herbicide effectiveness was affected by population density and plant development stage.

ABSTRACT: The knowledge on the mechanism that gives a weed resistance to a particular herbicide is essential regarding scientific, academic, and practical aspects because it determines the recommendations for prevention and management of resistance in the field. Studies on the sourgrass (Digitaria insularis) glyphosate resistance mechanism in the literature have not been conclusive. Thus, the aim of this research was to study and evaluate the putative resistance mechanisms whichgives sourgrass biotypes, the ability to survive after glyphosate application. For this, 14C-glyphosate leaf absorption and translocation were compared in the biotypes Matão (R), Campo Florido (MG), Diamantino (MT), and Iracemápolis (S) as a function of the time after its application. In addition, the possibility that the mechanism of resistance results from a mutation in the EPSPs-encoding gene was also studied. The biotypes S, R, MG, and MT absorbed similar amounts of 14C-glyphosate. The biotypes R, MG, and MT did not present differences in 14C-glyphosate translocation when compared to the biotype S. The sequencing of the EPSPs-encoding gene showed no mutation in the regions 106 and 182, which normally give resistance to glyphosate in the case of other species. No mutation in the EPSPs-encoding gene was observed. Therefore, they are not glyphosate resistance mechanisms for the evaluated biotypes.
Desempenhar um papel, causar uma impressão: vetores sociotécnicos no espaço ampliado da publicação independente
Authors: Muniz Jr. José de Souza
Published: May 2019

Resumo O presente artigo parte da análise das práticas e representações de publicadores que frequentam as feiras de arte impressa realizadas na cidade de São Paulo nos últimos anos para compreender os vetores sociotécnicos que organizam essas práticas e as materialidades dos objetos editoriais ali publicados e comercializados. Coloca-se, no centro da análise, a relação entre as tecnicidades (o códice, o papel e a impressão) mobilizadas por esses publicadores e certas concepções de passado, presente e futuro inscritas em seus investimentos individuais e coletivos, com destaque para a tensão entre o “retorno ao artesanal” e a pretensão de construir um futuro viável para a publicação. Conclui-se que as novas formas de fetichização do livro impresso estão condicionadas tanto pelas evoluções técnicas proporcionadas pelas tecnologias digitais como pela negação programática do livro convencional, identificado com o mercado editorial mainstream.

Abstract: The objective of this work was to evaluate the effect of the use of steel slag as a soil acidity corrective and of mycorrhizal fungi associated with phosphate fertilization on corn plants. The study was performed in a greenhouse, using 3-kg pots with a Typic Haplorthox, in a 4x5x2 factorial arrangement, with four acidity correction treatments (C1, correction with dolomitic limestone at a dose of 4 Mg ha-1; C2, correction with steel slag at a dose of 4 Mg ha-1; C3, correction with a 1:1 mixture of 2 Mg ha-1 dolomitic limestone and 2 Mg ha-1 steel slag; and C4, control, without pH correction), five phosphorus doses (0, 42, 95, 213, and 480 mg dm-3), and the presence or absence of two arbuscular mycorrhizal fungi (Rhizophagus clarus and Gigaspora margarita), with five replicates. Steel slag was efficient in correcting soil pH and providing Ca and Mg for the plants; therefore, it could replace limestone. The inoculation with R. clarus and G. margarita, associated with P doses of 42, 95, and 213 mg dm-3, improved the development of corn plants after 45 days, resulting in greater plant height, stem diameter, leaf area, and shoot and root dry matter.

Published: May 2019

Abstract: The objective of this work was to evaluate the effects of a slower chilling rate on the physical traits of 14-day aged top sirloin (gluteus medius) from F1 Angus x Nellore young bulls. Slight and lean beef carcasses (n = 30) were split in half and selected for control (2°C for 24 hours) and treatment (10°C for 10 hours followed by 2°C for 14 hours). Carcass temperature and pH decline were monitored in the longissimus dorsi (LD). Sarcomere length, color, and instrumental tenderness (Warner-Bratzler shear force and Volodkevich bite jaws) were measured on the gluteus medius (GM). pH 6.0 was reached when the LD temperature was very low, 3°C for the control and 6°C for the treatment. Differences in color and cooking losses were not significant. A trend was noticed for shorter sarcomere length and greater Warner-Bratzler shear force in the GM control. However, a lower value for Volodkevich bite jaws was found in the GM subjected to the treatment. The cooling regimes adopted were not sufficiently different to cause changes in color traits; however, the slow chilling of carcass improved tenderness and can be a good alternative to produce high-value cuts.

Abstract: The objective of this work was to evaluate the usefulness of a subset of 18 single nucleotide polymorphisms (SNPs) for breed identification of Brazilian Crioula, Morada Nova (MN), and Santa Inês (SI) sheep. Data of 588 animals were analyzed with the Structure software. Assignments higher than 90% confidence were observed in 82% of the studied samples. Most of the low-value assignments were observed in MN and SI breeds. Therefore, although there is a high reliability in this subset of 18 SNPs, it is not enough for an unequivocal assignment of the studied breeds, mainly of hair breeds. A more precise panel still needs to be developed for the widespread use in breed assignment.
A transgender person with haemophilia
Authors: Valk Caroline
Published: May 2019

Introduction

Transgender people face many obstacles to accessing healthcare but cultural changes are likely to increase provision of sex reassignment surgery in countries with sufficient resources. Haemophilia services traditionally focus on providing factor replacement therapy for males and should therefore understand how the care they provide can be adapted to meet the needs of transgender people. Haemophilia is an X-linked congenital bleeding disorder, caused by deficiency of coagulation factor VIII (haemophilia A) or factor IX (haemophilia B). The condition is passed on through carrier females, the majority of whom have a factor level high enough to allow for normal blood clotting. However, around 10% of carrier females are symptomatic and at risk of abnormal bleeding.

Case presentation

This case report describes a person with mild haemophilia A who, on first presentation to the haemophilia service, stated he was a transgender person in transition to becoming a male. Haemophilia was diagnosed when heavy bleeding occurred following bilateral mastectomy approximately 25 years previously. He now requested phalloplasty.

Management and outcome

Phalloplasty was performed at a hospital geographically separate from the haemophilia centre, requiring careful coordination between the two services. A haemophilia specialist nurse provided education and training about haemophilia and its management to the surgical nurses. Twenty-four-hour support was available from the nurse and a specialist doctor. Preparation and administration of clotting factor was the responsibility of the haemophilia nurse until the surgical team was confident in its use. Clotting factor replacement was managed using standard procedures, successfully maintaining factor VIII above a target level of 100% with a twice daily dose. Surgery went well, but wound healing was delayed, in part, due to persistent bleeding.

Discussion

Close collaboration between the haemophilia and surgical teams provided effective prophylaxis of bleeding during a complex procedure that presented new challenges. Both services now have better understanding of the needs of transgender people.
Sistemas intertextuales transmedia: exploraciones conceptuales y aproximaciones investigativas
Authors: Montoya Diego Fernando , Vásquez Arias Mauricio , Salinas Arboleda Harold
Published: May 2019

El presente artículo explora algunas de las discusiones teóricas que sobre el concepto de narrativas transmedia se vienen tejiendo actualmente, deteniéndose en particular sobre nociones clave como las de expansión narrativa y relaciones intertextuales, para finalizar indicando la necesidad de constituir una serie de referentes teóricos y metodológicos, que permitan abordar la diversidad de formas expresivas que constituyen los sistemas intertextuales transmedia.
La investigación en comunicación. Los límites y limitantes del conocimiento
Authors: Roncallo-Dow Sergio , Uribe-Jongbloed Enrique , Calderón-Reyes Isabel
Published: May 2019

Este artículo busca debatir las preguntas concernientes al campo de estudio de la comunicación, su objeto y el público objetivo de sus avances. Fuera de preguntarse sobre el qué y el porqué de la comunicación, cuestiona el rol de la medición bibliográfica como criterio suficiente para determinar la calidad de la investigación y propone abrir un debate público con los desarrollos investigativos del campo. El debate toma aspectos epistémicos del campo de estudio y confronta la visión positivista que limita actualmente las políticas gubernamentales sobre ciencia y tecnología. Finalmente se propone una visión más amplia de los problemas atinentes a la comunicación y se abren algunos interrogantes a propósito de la cienciometría como criterio de medición de calidad.
La actualidad del pensamiento político de Maquiavelo
Authors: Hermosa Andújar Antonio
Published: May 2019

Vencer mediante la gloria o la fama el cerco que con nuestra vida el tiempo pone a nuestra memoria fue el ideal del héroe antiguo; mantener en vida las gestas, y a sus autores, que merecían sobrevivir a su tiempo fue el ideal que se marcaron, junto a ciertos poetas, los historiadores antiguos, y por eso escribieron historia: para enseñar a la política modelos a adoptar y al futuro verdades eternas que aprender en aras de instituir un mejor orden social.
La inmortalidad de Ulises, entre Homero y Joyce
Authors: Rodríguez Freire Raúl
Published: May 2019

La reescritura de la Odisea de Homero, por parte de James Joyce, sigue siendo tema de debate. El presente artículo tiene por objetivo entregar claves de lectura que permitan comprender que Joyce sí reescribió el tema del Ulises en su obra, pero para comprender de qué manera lo hizo, es necesario revisar, primero, la transformación que sufrió el nombre de Ulises en La divina comedia de Dante y luego, entender la mirada histórica de Giambattista Vico, pues fueron sus reflexiones las que le permitieron a Joyce reescribir el tema homérico, pero a partir de su propio tiempo.
Tragedia y reaprehensión mítica
Authors: Vélez Upegui Mauricio
Published: May 2019

El texto que aquí presentamos invita a considerar la relación que puede ser establecida entre la tragedia ática y la tradición mítica griega. Luego de describir las condiciones culturales que hacen posible dicha relación, pasamos a formular la idea de que la fiesta religiosa dionisíaca organizada en forma de concurso teatral se fundamenta en un proceso de reaprehensión mítica que sirve de sustento al drama en general, y a la tragedia en particular. Solo que, a nuestro juicio, y tal es la conjetura que formulamos, la reaprehensión del mito que conduce al nuevo ordenamiento poético denominado tragedia entraña tres fases: a) de selección y modificación; b) de reestructuración; y c) de codificación. La consideración de los aspectos sociales y artísticos de cada una de estas fases contribuye a dotar de sentido la conjetura expuesta.
El futuro de las humanidades: Experimentando
Authors: Weber Samuel
Published: May 2019

¿Tienen las Humanidades futuro? ¿Hay lugar para el estudio de la literatura, el arte, el lenguaje y la filosofía en un mundo cada vez más dominado por una lógica económica de pérdida y ganancia? ¿Qué propósito pueden cumplir estas disciplinas frente a tecnologías que parecen estar volviendo rápidamente obsoleta la que fuese la función quizás más característica del "hombre", al menos desde el Renacimiento europeo: la función del trabajo productivo? El futuro de las Humanidades en un mundo de virtualización y de globalización no puede residir en la propagación continua de un modelo de unidad y totalidad para las sociedades o naciones.
Filosofía práctica impura y normativa
Authors: Lariguet Guillermo
Published: May 2019

En este trabajo defiendo una concepción de la filosofía práctica como disciplina impura y normativa. La impureza exige una mirada más sensible a elementos aportados por disciplinas empíricas y a revalorizar la importancia de la historia para el análisis conceptual. La normatividad requiere abandonar la pretensión de neutralidad de la filosofía práctica. Sostengo que la impureza y la normatividad hacen de la filosofía práctica una disciplina intelectualmente próspera. Para defender esta concepción, explicito una crítica a un modo erróneo de caracterizar la filosofía analítica. Además, distingo la filosofía teórica respecto de la filosofía práctica y explicito con qué rasgos de la filosofía analítica me comprometo.
Humanidades y media
Authors: Villacañas José Luis
Published: May 2019

Las humanidades en la sociedad de la comunicación deben dejar de ser un conjunto de saberes auto-referenciales, destinados a nutrir las señas de identidad endógenas de las elites académicas y de asegurar exclusivamente criterios de promoción profesional, y deben cooperar con la industria cultural de una forma eficaz, capaz de respetar la estructura de los lenguajes de la industria de masas, pero al mismo tiempo de dinamizar y actualizar el patrimonio cultural de las sociedades, generando nuevas formas de sentido común y de socialización, nuevas formas de vínculos efectivos capaces de respetar los hábitats que configuran la sociedad global, desde las historias que nos hablan de una única Tierra a las que nos hablan de comunidades reducidas. Sólo así podemos cumplir la promesa de una sociedad democrática y plural que va implícita tanto en la institución universitaria como en la industria.
Ensayo y humanismo
Authors: Weinberg Liliana
Published: May 2019

En el siguiente artículo se presenta una reflexión sobre las relaciones entre ensayo, humanismo y humanidades. Se procura caracterizar cada uno de estos términos a partir de una breve revisión de su etimología y su historia, así como también reparar en el estrecho vínculo que los une. Se detiene en particular en la figura de Miguel de Montaigne, ensayista y humanista, cuyo legado se considera de enorme actualidad. Se propone meditar sobre los alcances de la declaración de buena fe con que se abre la advertencia "Al lector". El trabajo se cierra con la interpretación de uno de los grandes temas tratados por Montaigne en sus Ensayos: el miedo, cuyas derivas individuales y sociales se hacen sentir en nuestros días de una manera renovada, como lo muestran ejemplos eminentes de la literatura contemporánea. Se proponen también algunas tareas para un "nuevo humanismo", abierto e incluyente.
Emigrar para vivir, servir para inmigrar. Legislaciones para las inmigraciones de judíos a América y Colombia entre 1880 y 1930
Authors: Navia Hoyos Mateo
Published: May 2019

En este artículo se presenta una aproximación al tratamiento otorgado a los judíos migrantes de Asia a América y Colombia entre 1880 y 1930, principalmente desde las legislaciones que se produjeron. Dicho contexto legal, acompañado de la mención a la discusión sobre la cuestión de la raza que se realizó en 1920, permiten plantear que en el contexto de la modernización que se estaba produciendo en el continente americano, los judíos que ingresaran a los países correspondientes debían comprometerse con los programas de desarrollo y progreso de las naciones.
Ciencias sociales e historia. Un balance de las formas de hacer: perspectivas de teoría y de investigación
Authors: Silva Renán
Published: May 2019

En el transcurso de estas páginas nos referiremos a la obra siempre por su título en francés, pues es difícil encontrar un equivalente preciso. ¿Hacer ciencias sociales? ¿Producir ciencias sociales? ¿Investigar en ciencias sociales? ¿Dedicarse a las ciencias sociales?, no me parecen títulos ni exactos ni atractivos, aunque todas son formas que recogen en parte la idea y espíritu de la obra. Por otra parte, hay que advertir desde ahora al lector que aunque se mencionan varias obras de Ciencias sociales e Historia –en general todas conocidas para un lector sin mayor especialización–, el texto no constituye un ensayo bibliográfico, y solo se ofrecen las referencias bibliográficas precisas en los casos en que así debe hacer por necesidades argumentales y de demostración.
Retórica, materialidades y prácticas del saber histórico en Colombia durante la segunda mitad del siglo XIX
Authors: Cardona Zuluaga Patricia
Published: May 2019

La retórica como técnica responsable de la inteligibilidad del discurso, de los modos y espacios de enunciación, de los propósitos y de los públicos, definió, hasta el siglo XIX, la existencia de los llamados géneros literarios devenidos en historia, literatura y periodismo, hoy áreas claramente diferenciadas. Sin la retórica la desmembración de los géneros literarios es incomprensible; se quedan de lado aspectos como las tradiciones narrativas, editoriales y didácticas que delimitaron los procedimientos de escritura, la implementación de formatos que contribuyó a perfilar usos, públicos y apropiaciones, y la disposición de representaciones sobre el quehacer de historiadores, periodistas y literatos. Este texto aborda algunos asuntos relativos a la constitución del saber histórico en Colombia y se detiene en la relación entre historia y formatos, e historia y escritores de historia.
Ensamblajes institucionales y guerras civiles en la Colombia del siglo XIX
Authors: Alonso Espinal Manuel Alberto
Published: May 2019

El objeto del artículo es presentar algunos elementos centrales de los ensamblajes institucionales en los cuales se insertaron las guerras civiles colombianas de la primera mitad del siglo XIX. Específicamente interesa destacar el peso que tuvo, en la primeras décadas de XIX, la demarcación de lo territorial a través de la referencia permanente a lo municipal, provincial y local; la delimitación de la autoridad en un contexto marcado por la presencia del caciquismo; y la definición de los derechos a través de hiperdesarrollo jurídico, la defensa del republicanismo y el miedo al pueblo.
Ius Constitutionale Commune en América Latina, de Armin von Bogdandy – Héctor Fix – Mariela Morales (coords.)
Authors: García Jaramillo Leonardo
Published: May 2019

Además del desafío propiamente jurídico que plantean la interamericanización del derecho y los proyectos que propugnan por un constitucionalismo transformador de las desigualdades sociales y políticas que aquejan a los países de la región, se plantean retos de naturaleza política. Sobresalen la inclusión social y la debida representación política. Dentro de los retos filosóficos se encuentra la depuración de conceptos que sofistiquen y precisen las categorías con las cuales describimos nuevos fenómenos en América Latina .
