Huge yolk sac tumor in an adolescent girl: a case report
Authors: Jain Amrita J. , Daver Rekha G. , Patil Anjali M.
Published: June 2017

Germ cell tumours form a minority of all malignancies of the ovary. The common age group affected by yolk sac tumours is 11 to 24 years. Here, we present a case of yolk sac tumour in a 13-year-old girl who came with complaints of abdominal pain, distension and acute febrile illness. Fertility sparing surgery (Unilateral salpingo-oophorectomy) was done while the contra lateral ovary and uterus was conserved followed by combination chemotherapy postoperatively. As pprognosis of yolk sac tumours is highly stage-dependent, an early diagnosis can result in a drastic difference in the final outcome of the treatment of this highly aggressive disease. Besides the rarity of the tumour, the importance of the fact, that a vigilant and informed clinician can make an early and timely diagnosis of this condition even in girls of such a young age and make a drastic difference in the final outcome of the treatment, compels us to present this case.

Published: June 2017

Background: Glaucoma is a group of eye diseases which result in damage to the optic nerve and ultimately vision loss. Elevated intraocular pressure (IOP) remains as the one major known risk factor for both the development and progression of glaucoma. Metabolic syndrome (MS) have been found to relate to elevated IOP. The aim of the study is to examine the association between MS and IOP by comparing central corneal thicknesses (CCT).Methods: The study was carried out with 169 subjects consists of 94 were clinically diagnosed MS patients and 75 are healthy controls. Serum fasting glucose, triglyceride and HDL cholesterol levels were measured, and waist circumference, body mass index and blood pressure of all patients were recorded. Ophthalmological examinations, including IOP and CCT measurements were done on everyone.Results: Higher IOP was observed in subjects with MS than those without MS. There was significant difference in the CCT values between the groups with and without MS (p<0.05). Most of the MS components were associated with IOP and CCT (p<0.05).Conclusions: The study concludes that components of MS have strong association with IOP and CCT. The prevalence of MS is increasing rapidly in developing countries and the main cause for MS is sedentary lifestyle. Since there is relationship between MS and IOP, lifestyle intervention might have therapeutic potential to reduce IOP. Further studies are warranted to bring about the possible underlying relationship between components of MS and IOP.
Optimal cut-off values for obesity using classification tree in middle-aged adults living Rio de Janeiro city
Authors: Materko Wollner , Santos Edil Luis
Published: June 2017

Background: The goal present study was to identify cut-off points for body mass index (BMI) and waist circumference (WC) to predict values of obesity based body fat percentage (BF%) using classification tree in middle-aged adults living Rio de Janeiro city, Brazil.Methods: The data was collected in a prospective cohort composed of 886 adults (443 men and 443 women) ranging from 30 to 59 years along two years (2010 - 2011) in Rio de Janeiro City, Brazil. All subjects were submitted to anthropometric evaluation and the gold standard was the percentage of body fat estimated by bioelectrical impedance analysis. The optimal sensitivity was achieved by adjusting BMI and WC cut-off values to predict obesity based on WHO criteria: BF% >25% in men and >35% in women according to the tree classification.Results: The best cut-off for BMI and WC were 28 kg/m2 and 99 cm, respectively, with a prediction of 99.4% overall tree sensitivity in men. For women, the best cut-off for BMI and WC were 26 kg/m2 and 90 cm, respectively, with a prediction of 90.1% overall tree sensitivity.Conclusions: The BMI and WC that corresponds to a BF% previously defining obesity is similar to other Western population, but different of the recommended by WHO and NCEP to BMI and WC thresholds, respectively, for defining obesity for both genders.

Published: June 2017

Background: In 1952 Schwartz coined the term “atrophica idiopathica mucosa oris” to describe an oral fibrosing disease he discovered in 5 Indian women from Kenya. Oral submucous fibrosis of oral cavity is a chronic progressive debilitating disease and premalignant condition of oral cavity. The condition is well recognized for its malignant potential and it is particularly associated with aracanut chewing. It is characterized by burning sensation in mouth particularly while eating spicy food and progressive development of inability to open mouth. Worldwide estimate of oral submucous fibrosis indicate that 2.5 million people are affected with a higher incidence in Indian subcontinent.

Methods: This is an observational type of study of 100 patients with oral submucous fibrosis attending ENT OPD.  

Results: We observed that with effective combination of treatment and avoiding predisposing factors and with long time follow-up we got markedly good results.

Conclusions: Although medical management does not completely cure the disease but optimal doses of injection corticosteroid with injection hyaluronidase with avoidance of predisposing factors and improvement of dietary habit with prolong follow up is effective in some extent.
Micro biological evaluation of aural swab culture and antibiotic sensitivity in 100 cases of tubotympanic and attico antral disease
Authors: R. Suneer , L. Sivasankari
Published: June 2017

Background: Chronic suppurative otitis media and its complications is one of the commonest ENT problems in our country. The chronicity of the disease and poor response to routine treatment prompted us to isolate and identify the causative organisms and study the antimicrobial susceptibility pattern.

Methods: About 50 patients with tubo tympanic disease and about 50 patients with attico-antral disease were selected, complete clinical ENT examination carried out, aural swabs were collected, culture was done and antibiotic sensitivity was studied.  

Results: Culture of aural swab demonstrate the polymicrobial bacteriology consisting of both gram positive and negative pathogens, while gram negative pathogens form the majority of both tubotympanic and atticoantral disease. Mixed growth is more common in attico- antral disease. In our study, Ciprofloxacin and Cefotoxime has found out to be the drug of choice for both tubotympanic and atticoantral disease with high sensitivity.

Conclusions: Periodical monitoring of microbiological profile is essential for making effective empirical protocol for the cases in a particular geographical location.

Published: June 2017

Background: Theoretical consideration suggests an impact of the age at tinnitus onset influencing tinnitus distress. The use of masking for tinnitus is a primary method of treatment of tinnitus. The objective was to study effectiveness of masking by introducing audiometric reference signal in treatment of subjective tinnitus.

Methods: The 90 patients (45 males and 45 females) were assessed by pure tone audiometer. Patients were divided into 6 age group sets for evaluation. The reference signal (90 to 100 dB SPL for 2-3 minutes in tinnitus ear of frequency 1000 Hz) was used for masking therapy. Outcome of the study was measured by using the tinnitus handicap inventory (THI) score and awareness time (tinnitus perception) before and after audiometric reference signal masking therapy. Success rate was measured to measure therapeutic efficacy.  

Results: Our results depict improvement in subjective tinnitus by 57.78% (in males), 55.56% (in females) and overall 56.67% success in patients aged between 21 to 60 years by using our audiometric reference signal masking therapy. Regarding gender, the finding of THI score, Awareness time and Success rate in our study showed females being affected more than males. Our study also evidenced a highest percentage of tinnitus after the age of 70 followed by the decades 61–70 and 51–60.
Conclusions: Our new economically viable approach to subjective tinnitus patients by audiometric reference signal seems to be an effective in improv­ing the patient’s distress in age group 21 to 60 years. Before taking decision for selection of high cost hearing aids, we can use it for poor people.
Molecular markers in thyroid cancers
Authors: Patel Alpa Nimesh , Singh Siddharth
Published: June 2017

Thyroid cancer is the most common of all endocrine tumors. In most countries, a steady increase in the incidence of thyroid cancer (mainly papillary
carcinomas) was observed in both sexes, whereas mortality has declined. Thyroid nodule is the most common presentation of thyroid cancer and
according to Bethesda reporting system is categorized into six different disease categories based on histopathological pattern. The indeterminate
categories require further investigation which is generally in the form of a surgical or invasive procedure for confirmation of nature of disease. Our
article is describing the various molecular markers that are linked with different subtypes of thyroid cancer and their usage in guiding diagnosis,
investigative approach and prognostication in thyroid cancer especially the indeterminate categories. We discuss the various tests available for us
currently for detecting the genetic alterations and thus help us frame further approach algorithms for detection of thyroid cancers.

Published: June 2017

Introduction: Lung cancer accounts for the highest mortality globally, and there is a need to find new strategies and novel treatment options. Lung cancer is genetically heterogeneous across various ethnic populations, and therefore identifying the mutational landscape in Indian patients is important. Methods: The aim of the pilot study is to identify the prevalence and temporal sequence of molecular lesions in lung cancer patients from a regional cancer institute in South India using the circulating tumor DNA technique. Genotyping was performed on 26 newly diagnosed metastatic lung cancer patients using Illumina Omni Express Exome. Chip data were inspected using Genome Studio and subsequently exported for use with PLINK and further annotation was performed. Results: Seven genes including TP53 (61.5%), MUC16 (57.6%), KRAS (38.4%), STK11 (19.2%), Epidermal growth factor receptor (15.3%), ataxia telangiectasia mutated (15.3%), and nuclear factor-κβ (7.6%) demonstrated high incidence of mutations in patients. The other genes identified were observed in <5% of patients. Several types of mutations including missense, silent, nonsense, and frameshift mutations were observed in these genes. Conclusion: Integration of mutational profiling to identify gene mutations is required to facilitate personalized lung cancer therapy.

Microseismic Magnitudes andb-Values for Delineating Hydraulic Fracturing and Depletion
Authors: Dohmen T.. , Zhang J.. , Barker L.. , Blangy J. P.
Published: June 2017

In 2014, Hess Corporation collected microseismic and hydraulic-fracturing data in a Bakken field trial near an existing oil well in the Williston Basin of North Dakota. In addition to monitoring the microseismic activity of the newly drilled offset-well completions, the field test delineated the depletion surrounding the original well by slowly repressurizing it. This repressurization induced shear-slip events, which preferentially delineated the depleted zone of the producer well, a process we call microseismic depletion delineation (MDD).

By comparing the magnitudes of the depletion-related events to those that accompanied the new offset completions, we observe that higher magnitude microseismic events occur within the depleted interval. This paper offers an explanation for why higher magnitudes appear in the depleted zone and suggests that measuring magnitude statistics in the form of b-values can provide a qualitative assessment of the relative contribution of oil from completions along a wellbore.

Published: June 2017

Islamic Banking has gained enormous popularity in Pakistan in a short span of time and still has a huge potential to grow in the market. Many Conventional Banks having Islamic Banking windows and a few full-fledged Islamic banks are striving hard to remain alive in the stiff competition for market share, resulting in more banking choices for the customers. Still there is lot to be achieved and the whole banking system has to get rid of the curse in the form of Riba, which has strongly been denounced and prohibited in the Holy Quran. Islamic Banks at the moment hold merely 9.4% of the whole banking Market which is far below than desired. In this study, an attempt will be made to analyze the growth trends in the Islamic banking and its implications for the society and the economy in particular. Customersâ€™ perceptions & expectations and certain myths regarding Islamic banking will also be captured during the study. This will not only help us in understanding the potential and opportunities available in the industry but also give an idea that what the customers want and expect from Islamic banking. Moreover, the study will also add to the latest pool of knowledge on the subject. There seems a dearth of updated quality research on the matter and this will serve as an important reference and latest work on Islamic Banking in Pakistan.

Published: June 2017

From point of view geotechnical parameters evaluation (classifications, interpretations) it is important to determine organic matter content correctly. Most frequently approach is to use for that purpose direct method – loss on ignition at different temperatures. Key factors which influence choosing that approach are: simplicity of this method and non-complex equipment. Thereby, much less used are indirect methods – volumetric. One of indirect methods is common known Tiurin’s method. Organic matter content depends not only from applied method. In case of direct method – loss on ignition at different temperatures, temperature which is applied in examination has also influence on organic matter content. The following article presents results of examinations which gave opportunity to determine to what extent chosen method influences value of organic matter content. The authors were investigated what infl uence has applied temperature in the loss of ignition method. For that purpose as a reference Tiurin’s method was chosen, which generally outputs values lower than the method loss on ignition at different temperatures.
Collaborative planning for city development. A perspective from a city planner
Authors: Purbani Kamalia
Published: June 2017

A number of definitions related to collaborative governance have been developed since early 2000. The common characteristics of collaborative governance are, among others, policy consensus, community visioning, consensus rule-making, and collaborative network structures. Collaborative planning is a new paradigm of planning for a complex contemporary society through which it encourages people to be engaged in a dialogue in a situation of equal empowerment and shared information to learn new ideas through mutual understanding, to create innovative outcomes and to build institutional capacity. This indicates that collaborative planning can provide policy makers with more effective community participation. Collaborative process is the key of collaborative planning which also emphasizes the significant role of collaborative leadership. The process includes a participatory activity of dialogue oriented to the joint decision and summarized in a collaborative process. The collaborative leadership is crucial for setting and maintaining clear ground rules, building trust, facilitating dialogue, and exploring mutual gains. Along with the shift of planning paradigm, the role of city planner will also change since the city planning deals with the political process. In the political process, city planners must be able to perform as technocrats, bureaucrats, lawyers and politicians who always uphold their ethics because they are responsible to the society, the assignor for their integrity and professionalism.

Published: June 2017

Transformations of high-molecular-weight compounds of oil sand natural bitumen under the heat treatment were studied in this work. For that purpose the natural bitumen isolated from oil sand taken from the Beke field (Kazakhstan) was used as a substrate. Thermal processing of natural bitumen leads to a general change in the chemical composition of components and to an increase in the output of certain fractions. The contents of oil, tar and asphaltenes were determined and the elemental composition of tar-asphaltene compounds was evaluated. Molecular structures of the tar and asphaltene components of natural bitumen before and after cracking have been defined from the data of elemental analysis, NMR spectroscopy and molecular weight. The high molecular compounds were presented as giant molecules containing small aromatic islands some of which were linked by aliphatic chains, that was proved by infrared spectroscopy.

Six new organotin(IV) derivatives [Me3SnL1] (1), [Bu3SnL1] (2), [Ph3SnL1] (3), [Me3SnL2] (4), [Bu3SnL2] (5) and [Ph3SnL2] (6) (where HL1 = = 9-fluoro-6,7-dihydro-5-methyl-1-oxo-1H,5H-pyrido[3,2,1-ij]quinoline-2-carboxylic acid (flumequine) and HL2 = 2-[2-[4-[(4-chlorophenyl)phenylmethyl]- -1-piperazinyl]ethoxy] acetic acid (cetirizine)) were synthesized and characterized by elemental analysis, FT-IR spectroscopy, multinuclear 1H-, 13C- and 119Sn-NMR, mass spectrometry and thermal analysis techniques. The obtained data reveal trigonal-bipyramidal geometry in case of complexes 1, 2, 4 and 5, and tetrahedral geometry for complexes 3 and 6 around the tin atom, whereas in complexes 3 and 6 the carboxylate ligand act as monodentate ligand through one of its oxygen atoms while it acts as bidentate ligand through two oxygen atoms for complexes 1, 2, 4 and 5. The antibacterial and antifungal efficacies of complexes 1?6 were assessed and the majority of the compounds showed good activities. The present research showed that the trimethyltin(IV) derivatives were particularly more effective than tributyltin(IV) and triphenyltin(IV) derivatives against all the bacterial and fungal strains. Antioxidant and DNA binding studies were also performed and promising results were obtained.

Published: June 2017

The analytical capability of laser-produced plasma for the analysis of low alloying elements in cast iron samples has been investigated. The plasma was induced by irradiation of a sample in air at atmospheric pressure using an infrared CO2 laser. Emission spectra were recorded by time-integrated spatially- resolved measurement technique. A set of ten cast iron samples in a powder or particulate form were provided by BAM (Bundesanstalt f?r Material Forschung und Pr?fung, Deutschland), seven of which were used for calibration, and three were treated as unknowns. Linear calibration curves were obtained for copper, chromium, and nickel, with correlation coefficients above 0.99. Precision and accuracy of the LIBS method was evaluated and compared to those obtained by the inductively coupled plasma (ICP) analysis of the same samples. Detection limits for Cu, Cr and Ni were close to those reported in the literature for other comparable iron-based alloys obtained using different LIBS systems. Analytical figures of merit of the studied LIBS system may be considered as satisfying, especially in the light of other advantages of the method, like cost effective and fast analysis with no sample preparation, and with a possibility for real-time on-site analysis.
A epistemologia instrumentalista de Dewey e os novos problemas filosóficos da era pós-darwinista
Authors: Nascimento Edna Maria Magalhães do
Published: June 2017

O presente artigo é parte de uma investigação mais ampla sobre a Epistemologia Naturalista e Realista de Dewey e sua contribuição para a filosofia no século XXI, desenvolvida na Universidade de Navarra, em estágio pós-doutoral. Com base neste contexto, delimitamos a presente análise sobre o método instrumentalista de Dewey e os problemas filosóficos que resultaram para a filosofia numa etapa pós-darwinista. O objetivo da presente pesquisa é num primeiro momento caracterizar o instrumentalismo de Dewey, bem como trazer à discussão que Dewey empreendeu no seu famoso ensaio “The Influence of Darwinism on Philosophy”(1909), acerca das tarefas postas para a filosofia após as descobertas darwinianas sobre o principio de transação dos fenômenos vivos. Concluímos que Dewey concentrou-se em provar que a filosofia tem um papel importante quanta à discussão das implicações da teoria darwiniana para o conhecimento. Num segundo momento, situaremos o instrumentalismo de Dewey como herdeiro de uma arquitetura teórica da modernidade com base em dois movimentos: o Iluminismo e o Contra-Iluminismo.  Concluiremos à luz de Lavine (1995) que concepção de ciência desenvolvida por Dewey é sustentada pela a ideia de que a ciência e democracia compartilham não apenas o mesmo padrão de investigação, o "método da inteligência", mas também as mesmas virtudes morais: uma disposição para questionar, para procurar clareza e evidência, para ouvir e respeitar as opiniões dos outros, para considerar alternativas de forma imparcial, para mudar de ponto de vista em virtude da investigação e da comunicação.

Published: June 2017

Oksidi sumpora, koji nastaju sagorevanjem goriva koja sadrže sumpor (ugalj, nafta), predstav-ljaju gasove staklene bašte sa indirektnim dejstvom. Poznato je da ovi gasovi imaju nepovoljan uticaj na životnu sredinu i zdravlje ljudi, dovodeći do pojave kiselih kiša i respiratornih problema. Za ubla-žavanje klimatskih promena, neophodno je izvršiti smanjenje emisija gasova sa efektom staklene bašte među koje spadaju i sumporni oksidi iz termoenergetskih postrojenja.

Emisije gasova staklene bašte sa štetnim efektima su ograničene propisima EU i Republika Srbija se suočava sa nizom obaveza u pogledu smanjenja emisija ovih gasova u narednim godinama u procesu pridruživanja Evropskoj uniji.Glavnu ulogu u ovoj problematici dobili su mokri postupci koji se mogu klasifikovati kao nere-generativni (sa jednim prolazom) i regenerativni. U dosadašnjoj praksi najčešće je primenjivan nere-generativni krečnjački postupak. U ovom procesu alkalna smeša je reagens i gips je konačni proizvod. Nedostatak procesa je proizvodnja velike količine čvrstog otpada. Pri regenerativnim postupcima dolazi do termalne regeneracije solventa koji se vraća natrag u proces. Među najzastupljenijim rege-nerativnim postupcima su proces hemijske apsorpcije u aminima i proces fizičke apsorpcije u organ-skim rastvaračima.

Za kompjuterske simulacije, dizajn opreme i njihovu implementaciju u proces odsumporavanja dimnih gasova, neophodni su pouzdani podaci za termofizičke i transportne osobine potencijalnih rastvarača. Sa tim ciljem urađeno je modelovanje termofizičkih svojstava, za potencijalne apsorbente u regenerativnim postupcima odsumporavanja dimnih gasova, baziranih na procesu hemijske ili fizič-ke apsorpcije u organskim rastvaračima.

PROCEDURES The left forelimb of each dog was instrumented with 19 anatomic markers. X-ray fluoroscopy was used to optimize marker positions and perform scientific rotoscoping for 1 dog. Inverse dynamics were computed for each dog during a walk and trot on the basis of data obtained from an infrared motion-capture system and instrumented quad-band treadmill. Morphometric data were obtained from a virtual reconstruction of the left forelimb generated from a CT scan of the same dog that underwent scientific rotoscoping.

RESULTS Segmental angles, torque, and power patterns were described for the scapula, humerus, ulna, and carpus segments in body frame. For the scapula and humerus, the kinematics and dynamics determined from fluoroscopy-based data varied substantially from those determined from the marker-based data. The dominant action of scapular rotation for forelimb kinematics was confirmed. Directional changes in the torque and power patterns for each segment were fairly consistent between the 2 gaits, but the amplitude of those changes was often greater at a trot than at a walk.

CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that control of the forelimb joints of dogs is similar for both a walk and trot. Rotation of the forelimb around its longitudinal axis and motion of the scapula should be reconsidered in the evaluation of musculoskeletal diseases, especially before and after treatment or rehabilitation.

OBJECTIVE To determine factors affecting race speed in Swedish Standardbred horses undergoing surgery of the carpal flexor sheath (CFS), to investigate whether preoperative racing speed was associated with specific intraoperative findings and whether horses returned to racing, and to compare the performance of horses undergoing surgery of the CFS with that of age- and sex-matched control horses.

ANIMALS 149 Swedish Standardbred trotters undergoing surgery of the CFS and 274 age- and sex-matched control horses.

PROCEDURES Medical records of CFS horses were examined. Racing data for CFS and control horses were retrieved from official online records. Generalizing estimating equations were used to examine overall and presurgery racing speeds and the association of preoperative clinical and intraoperative findings with preoperative and postoperative speeds. Multivariable regression analysis was used to examine career earnings and number of career races. Kaplan-Meier survival analysis was used to compare career longevity between CFS and control horses.

RESULTS CFS horses were significantly faster than control horses. The CFS horses that raced before surgery were slower as they approached the surgery date, but race speed increased after surgery. There were 124 of 137 (90.5%) CFS horses that raced after surgery. No intrathecal pathological findings were significantly associated with preoperative racing speed. Career longevity did not differ between CFS and control horses.

CONCLUSIONS AND CLINICAL RELEVANCE Horses undergoing surgery of the CFS had a good prognosis to return to racing after surgery. Racing careers of horses undergoing surgery of the CFS were not significantly different from racing careers of control horses.

OBJECTIVE To characterize pharmacokinetics of cyclophosphamide and 4-hydoxycyclophosphamide (4-OHCP) in the plasma of healthy cats after oral, IV, and IP administration of cyclophosphamide.

ANIMALS 6 healthy adult cats.

PROCEDURES Cats were randomly assigned to receive cyclophosphamide (200 mg/m2) via each of 3 routes of administration (oral, IV, and IP); there was a 30-day washout period between successive treatments. Plasma samples were obtained at various time points for up to 8 hours after administration. Samples were treated with semicarbazide hydrochloride to trap the 4-OHCP in stable form, which allowed for cyclophosphamide and trapped 4-OHCP to be simultaneously measured by use of tandem mass spectrometry. Pharmacokinetic parameters were determined from drug concentration-versus-time data for both cyclophosphamide and 4-OHCP.

RESULTS Cyclophosphamide was tolerated well regardless of route of administration. Pharmacokinetic parameters for 4-OHCP were similar after oral, IV, and IP administration. Area under the concentration-time curve for cyclophosphamide was lower after oral administration than after IV or IP administration.

CONCLUSIONS AND CLINICAL RELEVANCE Cyclophosphamide can be administered interchangeably to cats as oral, IV, and IP formulations, which should provide benefits with regard to cost and ease of administration to certain feline patients.

DE CÓMO UN RÉGIMEN DE GESTIÓN SE CONVIRTIÓ EN IMPERATIVO CATEGÓRICO DE LA UNIVERSIDAD
Authors: Hleap Borrero José
Published: June 2017

En este artículo se busca indagar, poniendo en juego las ideas de autonomía, universalidad y convicción, la manera sutil como se ha ido transformando el ethos de las universidades públicas en América Latina, pasando del concepto de bien público de prestación estatal ligado tanto a la crítica del conocimiento —de sus contenidos y de sus usos— como a la búsqueda de caminos propios para el desarrollo latinoamericano –, y por tanto a una idea del vivir bien en instituciones justas-, a la de servicio público, función instrumental que desactiva la comunidad académica, su autoridad y dignidad, para otorgársela a un régimen de gestión (procedimientos y controles ligados a conceptos abstractos de eficiencia y eficacia, originados en el mundo empresarial) que funge como imperativo categórico del nuevo ethos universitario.
¿CONDICIONES DE VERDAD O CONDICIONES DE SATISFACCIÓN? REVISITANDO LA DISTINCIÓN AUSTINIANA DE LAS EMISIONES
Authors: Giraldo Chavarriaga John Alexander
Published: June 2017

El marco de esta reflexión es la delimitación preliminar de las emisiones realizativas, hecha por Austin en las seis primeras conferencias de How to do things with words. Considero aquí una de las distinciones de la filosofía analítica que más ha contribuido a aclarar la noción de sentido de los enunciados, la distinción entre constatativas y realizativas. Dejaré de lado la consideración de ambos tipos de emisiones como especies de actos lingüísticos en la teoría más general de los actos de habla, para centrar mi análisis en algunas condiciones que son comunes al uso de tales emisiones. La adecuación de esta distinción se logrará mostrando que la diferencia entre ambos tipos de emisiones no es de especie sino de grado y generalidad: las constatativas son un tipo especial de las realizativas, que fijan las condiciones generales de validez del discurso y se someten por igual a la doctrina de los infortunios.
El ethos, de la retórica al análisis del discurso. Análisis de caso: La imagen de las FARC en lasconversaciones de paz
Authors: Vásquez Ramírez Teresita
Published: June 2017

Algunos estudiosos del discurso han propuesto ciertos desplazamientos en la noción de ethos aristotélico que han hecho posible análisis más detallados a la hora de revisar la imagen de sí que construye el orador en su discurso. Desde la perspectiva de la semiótica discursiva se ha planteado ampliar esta noción a tres lugares del discurso en los que se configura la identidad discursiva: el enunciador, el enunciatario y el referente. Igualmente, se ha propuesto homologar las causas de la persuasión presentadas por Aristóteles, la sensatez, la virtud y la benevolencia, a las dimensiones cognitiva, axiológica y afectiva de los sujetos discursivos. En el análisis del ethos de las Farc nos proponemos dar cuenta de la funcionalidad de estos planteamientos.
El periodismo de El Liberal ante las elecciones: precaria guía para el lector-elector
Authors: Ruiz Echeverry Piedad
Published: June 2017

El estudio de 312 notas periodísticas del diario El Liberal, relativas a los procesos de elección popular de alcaldes en Popayán durante los años 1988, 1994 y 2003, permitió un análisis histórico sobre el tratamiento periodístico del tema de las elecciones políticas. Partiendo de que la información es un bien público, se asume que el tema electoral debe tratarse en los medios para promover una opinión pública con criterios claros de decisión política, cosa que no sucede según los hallazgos. El análisis de resultados se hizo a partir de una base de datos que incluyó variables como autoría, géneros, contexto, recursos visuales, candidatos mencionados, espacio, temas o publicidad política. Con ello se estudiaron dos grandes aspectos: el uso de recursos periodísticos y el equilibrio informativo, lo cual permitió concluir la ausencia de una tendencia clara hacia el mejoramiento del tratamiento noticioso de las elecciones por parte del periódico en torno a los procesos electorales.

Diseño: excusa para un comentario sobre epistemología
Authors: Romero Alberto
Published: June 2017

El siguiente texto tiene como propósito dialogar con un fragmento del pensamiento de Michel Foucault y orientar el diálogo hacia la formulación de preguntas sobre la fundamentación epistemológica y la noción de diseño. El propósito central del texto es el de inspeccionar, desde el ejercicio metódico sobre la formación del discurso, la noción de épistéme y sus valores constitutivos como eje y fundamento de la comprensión y la instauración de las formas de análisis particulares al diseño; entendida la épistéme como territorio de relaciones y como lugar de múltiples discursos. Además, se pretende vincular la mencionada inspección, así como el propósito localizador y ordenador de la noción de discurso con su funcionamiento e institucionalización. Esto, en el marco de la reflexión sobre la función política del intelectual, en el que, pensar las disciplinas e intentar reconstruir las épistémes sería ya una función política.

Del usuario al artista mundano: Facebook como ámbito de creación y poetización de la vida
Authors: Gómez Zúñiga Rocío
Published: June 2017

Banalizado, pordebajeado, tenido como un ámbito de exposición excesiva y narcisa de la persona, en este artículo Facebook se propone como ámbito de creación y poetización de la vida al examinar y entender las inversiones de tiempo, recursos y sentidos que el usuario pone en juego para construir y actualizar su página. Basado en una investigación realizada entre 2011 y 2013, el artículo pretende sustentar la noción, por supuesto polémica, de artista mundano, como manera de designar al sujeto que procura una variedad de obras expresivas en Facebook. Finalmente ofrece algunas pistas para pensar las relaciones entre jóvenes, educación y nuevos repertorios tecnológicos.
