Combination of hydrologic and hydraulic modeling on flood and inundation warning: case study at Tra Khuc-Ve River basin in Vietnam
Authors: Thai Tran Hong , Tri Doan Quang
Published: June 2019

Flooding caused by historically high flows, especially in Tra Khuc-Ve River basin in the Mid-Central region in Vietnam in November 2013, which caused widespread damage. The purpose of this paper was to establish the inundation maps in the downstream part of Tra Khuc-Ve rivers by using the coupling of the hydrological and hydraulic models (MIKE SHE/MIKE 11 and MIKE 11 GIS). Calibration and validation of the hydrological model were in good agreement in terms of the vibration amplitude, absolute value, and phases. The hydraulic model results showed good agreement between observed and simulated flood events in 2012 and 2013 after calibration and validation. The rainfall forecasting from the IFS model was also used to establish six flood warning scenarios based on the alarm level III (6.5 m) and the historical level (8.76 m). The inundation maps showed the extent of flooding and the water depth in the downstream part of the study area. The simulation results of historical data showed that Tu Nghia and Son Tinh Districts were the most affected areas by inundation with over 11% affected area while Quang Ngai Town inundated 8.1%. The study results will support decision makers in planning to reduce the impacts of natural disasters in Tra Khuc-Ve River basin in the future.

Published: June 2019

У  сучасних конденсаторах систем кондиціонування повітря, теплових насосів, випарниках систем опріснювання морської води і нагрівачах електростанцій процес конденсації пари здійснюється переважно у середині горизонтальних труб і каналів.  Процеси теплообміну,  що відбуваються у теплообмінниках цього типу, мають суттєвий вплив на загальну енергоефективність таких систем. У даній роботі представлено експериментальні дослідження теплообміну у разі конденсації холодоагентів R22, R406A, R407C  у гладкій  горизонтальній  трубі  з  внутрішнім діаметром d = 17 мм  за  наступними режимними  параметрами:температура насичення  35 - 40ºC, масова швидкість 10 - 100 кг/кв.м/c, масовий паровміст 0,1 - 0,8, питомий тепловий потік 5 ‑ 50 кВт/кв.м,  різниця  між  температурою конденсації та температурою стінки труби 4 - 14 К.  Вимірювання локальних за перерізом труби теплових потоків і коефіцієнтів тепловіддачі проводились за методом «товстої стінки»  під час різних режимів конденсації.  За результатами досліджень установлено, що у верхній частині труби з підвищенням теплового потоку зростає товщина плівки конденсату,  що призводить до зменшення тепловіддачі.  У  нижній частині труби збільшення теплового потоку підвищує тепловіддачу, що характерно для турбулентної течії рідини в трубі. Отримані результати роботи дозволили покращити метод розрахунку теплообміну у разі конденсації пари, яка ураховує вплив течії конденсату у нижній частині труби на теплообмін.  Цей метод із достатньою точністю (похибка ±30%) узагальнює експериментальні дані під час конденсації пари  холодоагентів R22, R134a, R123, R125, R32, R410a за умови стратифікованого потоку. Використання цього методу у разі проектування теплообмінних апаратів, які використовують такі типи речовин, підвищить ефективність енергетичних систем.

This article was migrated. The article was marked as recommended. IntroductionThe study investigated students' perception of introducing blended learning strategies to engage and motivate them towards lecture halls and Problem Based Learning (PBL) sessions for improving the quality of the overall students' learning experience.MethodsA prospective study was conducted at the Aga Khan University Medical College involving a total of one hundred four (104) year II medical students for the Endocrine and Reproduction module in the academic year 2018. This module ran for six weeks. Modifications in teaching methods were made for this module introduced after approval from Endocrine & Reproduction module, year II and curriculum committees. Written informed consent was obtained from facilitators and students. To assess the effectiveness of modifications introduced, students' feedback was taken on a Likert's scale of 1-5, at the end of the module. Data were analyzed by SPSS version 20.ResultsTotal 94 (90%) students participated in the written feedback. Forty percent medical students (n=38) responded that videos were useful, 54% (n=51) acknowledged that post-PBL activities like crossword puzzles and Kahoot games, created significant discussions amongst students in a fun yet intellectual manner. Seventy percent of students (n=66) agreed that access to Kahoot was easy and no connectivity issues were faced. Twenty percent students (n=20) endorsed that flipped lectures enhanced understanding of topics, 87% students (n=82) felt that recorded lecture was very helpful and flash cards were found helpful by 14% students (n=12).ConclusionStudent engagement is an important issue in medical schools in this era. Results showed that blended learning and educational activities enhanced students' learning motivation and interest.
A new method for predicting the ultimate shaft resistance of rock-socketed drilled shafts
Authors: Xu Jiang , Gong Weiming , Gamage Ranjith Pathegama , Zhang Qi , Dai Guoliang
Published: June 2019

Data from 187 loading tests on rock-socketed shafts are used to develop a new relationship between the ultimate shaft resistance fsuand unconfined compressive strength σcof intact rock. The adhesion factor αqof the shaft resistance for different types of rock and the relationship between αqand the embedment ratio are discussed. Furthermore, because the shafts are socketed in the natural rock mass, as well as the aforementioned correlation with intact rock, three new relationships between fsuand the unconfined compressive strength σcmof the rock mass are proposed by considering the rock quality designation, which is related to discontinuity of the rock mass. Statistical methods are used to evaluate and verify the existing methods and newly proposed relationships. Results obtained using the new relationship based on σcare found to be more accurate than those obtained using existing methods, and when the rock quality designation is available, results obtained using σcmare closer to measured values than those based on σc. The value of αqof the discussed rocks decreases with σc. Mudstone and shale have relatively high values of αqwith more dispersion, whereas αqvalues for gneiss, basalt and granite are small overall with less dispersion.

Published: June 2019

In a present study, the performance of a vapour compression–absorption cascaded refrigeration system (CRS) under fouled conditions was analysed. The main effect of fouling is to decrease the effectiveness of the heat exchanger. Thus, the overall conductance (UA) of the heat exchanger is decreased. Hence, another interpretation of fouling is to reduce the effective size of the heat exchanger. In the present work, the percentage decrease in the overall conductance value (UA) of evaporator and condenser due to their fouling is varied from 0 to 50% and its consequences on various aspects of CRS are generated to ascertain any possible patterns. The detailed first law analysis reveals that for a clean evaporator and condenser, the electricity consumption is 67.5% less than vapour compression system (VCS) for the same cooling capacity. CRS is able to save only 61.3% of electrical energy when evaporator and condenser conductance is reduced by 50% due to fouling. Evaporator and condenser fouling decreased the COP and rational efficiency of the system by 4.7% and 10.5% respectively. It is also important to note that irreversibility in the evaporator and condenser is increased by 42.4% and 62.1% respectively, when their individual performance is degraded by 50% due to fouling.
Mapping wind power density for Zimbabwe: a suitable Weibull-parameter calculation method
Authors: Hove Tawanda , Madiye Luxmore , Musademba Downmore
Published: June 2019

The two-parameter Weibull probability distribution function is versatile for modelling wind speed frequency distribution and for estimating the energy delivery potential of wind energy systems if its shape and scale parameters, k and c, are correctly determined from wind records. In this study, different methods for determining Weibull k and c from wind speed measurements are reviewed and applied at four sample meteorological stations in Zimbabwe. The appropriateness of each method in modelling the wind data is appraised by its accuracy in predicting the power density using relative deviation and normalised root mean square error. From the methods considered, the graphical method proved to imitate the wind data most closely followed by the standard deviation method. The Rayleigh distribution (k=2 is also generated and compared with the wind speed data. The Weibull parameters were calculated by the graphical method for fourteen stations at which hourly wind speed data was available. These values were then used, with the assistance of appropriate boundary layer models, in the mapping of a wind power density map at 50m hub height for Zimbabwe.
Contemporary wind generators

Published: June 2019

It is believed that wind energy is growing at a very rapid rate, especially in the last few years. When compared with other sources of renewable energy in the energy portfolio, it becomes evident that the bulk is wind energy-based. However, there are some backlogs to full manifestation of this technology ranging from initial high cost to performance and reliability issues, among others. But in spite of these bottlenecks, new research trends have been assertive in seeking out a sustainable solution for harnessing wind energy for power generation – especially in the design and construction of wind generators. In order to motivate and prime a sustainable energy mix among stakeholders, this paper is a shot at appraising the theory of these innovative wind generators towards ecological sustainability, economy, efficiency, and employment creation.

TARİHSEL SÜREÇTEN GÜNÜMÜZE MECLİSİN, DEVLET YÖNETİMİ VE KARAR ALMA ÜZERİNE ETKİSİ

Published: June 2019

Tarihsel süreçten günümüze kadar kurulan Türk
Devletlerindeki meclis yapılanmasının rolü ve işlevi teorik bağlamda ele
alınarak, meclisin devlet yönetimi ve karar alma üzerindeki etkisinin
incelendiği bu çalışmada, genel olarak meclisin devlet yönetimi üzerinde etkin
bir rolünün olduğu, karar alma bağlamında meclisin en üst karar alma
organlarından biri olduğu sonucuna ulaşılmıştır. Bununla birlikte tarihsel
süreç içinde zaman zaman meclis kurumunun devlet yönetimi ve karar alma
bağlamında etkisiz kaldığı dönemler de bulunmaktadır. Osmanlının yükselme devri
ile birlikte meclis kurumunun devlet yönetiminde etkisiz ve karar almada
yetkisiz bir kuruma dönüşmüş, tüm yetkiler padişahta toplanmıştır. Osmanlının
son dönemlerinde meclis, devlet yönetiminde yeniden etkin bir kuruma
dönüştürülmeye çalışılsa da, yapılan düzenlemeler yetersiz kalmış ve karar alma
noktasında padişahın meclis üzerindeki etkisi giderilememiştir.

Türkiye Cumhuriyetinin kurulması ile birlikte yapılan
anayasal düzenlemeler ile yasama, yürütme ve yargı güçleri ayrılmış, devlet
yönetiminde meclis yasama ve yürütmeyi denetleme işlevlerine kavuşturulmuştur.
Ancak 1923-1950 döneminde tek partili sistemin hayatta olması nedeniyle,
meclisin yürütmeyi denetleme veya kısıtlama işlevlerinin anayasal anlamda ve
modern devlet yönetimi bağlamında yerine getirmesi mümkün olmamıştır. Çok
partili dönemde meclis asli fonksiyonlarına döndürülmüş olsa da, askeri
darbeler, siyasal çekişmeler vb. gibi nedenler yüzünden meclis asli
fonksiyonlarından uzaklaşmış, kimi zaman yönetim tıkanıklarının da asli unsuru
haline gelmiştir. 16 Nisan 2017 tarihli referandum ile başlayan ve 24 Haziran
2018 tarihli seçimler ile hayata geçirilen Cumhurbaşkanlığı Yönetim veya
Hükümet Sistemi ile meclis, devlet yönetiminde asli fonksiyonu olan yasama
faaliyetlerine döndürülmüş, yürütme üzerindeki olumsuz (güvenoyu, gensoru, vb.)
etkileri de ortadan kaldırılmıştır.

Türk Devlet geleneğinde meclis kurumu vazgeçilmez ve asli bir unsur
olarak her zaman var olmuş ve bundan sonraki süreçlerde de var olacaktır. Ancak
meclisin devlet yönetimi ve karar alma bağlamında, yürütmeyi kısıtlayıcı ve
yürütme üzerinde tahakküm kuran bir kurumdan ziyade, yasama ve denetleme
fonksiyonları ile etkin bir kurum olması gerekmektedir. Dolayısı ile meclisler
hükümet veya devlet yıkan bir kurum olmak yerine, asli görevlerini yerine
getiren bir kurum olarak var olmalıdırlar. Bununla birlikte devletlerin
devamlılığı ve etkin bir devlet yönetimi için, güçler ayrılığı ilkesinden taviz
verilmemeli, yasama, yürütme ve yargı erkleri anayasal çerçevede bağımsız ve
birbirleri üzerinde tahakküm kurmadan faaliyetlerini yürütmeleri gerekmektedir.

Making low peptone NGM for imaging plates v2
Authors: Islam Priota
Published: June 2019

C. elegans is maintained in the laboratory on Nematode Growth Medium (NGM) agar which has been aseptically poured into petri plates. The NGM agar medium can be poured into petri plates easily and aseptically using a peristaltic pump. This pump can be adjusted so that a constant amount of NGM agar is dispensed into each petri plate. A constant amount of agar in the plates reduces the need for refocusing the microscope when you switch from one plate to another. For imaging purposes, low peptone NGM is prepared which contains less concentration of bactopeptone as compared to the normal NGM. This is because we don't want the seeded bacteria to grow too much and obscure the images, rather just sufficient enough to keep the worms from crawling out of the plate due to lack of food. The imaging plates can be 35mm, 60mm or 90mm in diameter depending on the assay design.

Does public procurement for innovation increase innovative efforts? The case of Brazil
Authors: Rocha Frederico
Published: June 2019

The paper uses microdata from the Brazilian Innovation Survey  to assess the effect of public procurement on firms’ private R&D expenditures. The PINTEC 2014 edition included in its  policy  module  a  new  question about  public  procurement  related  to  firms’  innovative  activities. The paper uses this information to define a treated sample composed by firms that participated  in  public  procurement  with  innovative attributes.  The  paper  builds  a  control  sample through coarsened exact matching and tests the effect of innovation-related public procurement on firms’ private R&D to sales ratio. The results suggest a positive impact of public procurement of innovation on R&D intensity. Data also shows that most firms involved in PPI are small and belong to low-technology sectors. These features disclose an important characteristic of the public procurement of innovation: its ability to target small firms and contribute to local development.
Energy efficiency improvement in the system for drying baker`s yeast
Authors: Anastasovski Aleksandar Kosta
Published: June 2019

Drying processes are one of the main consumers of heat energy in production. Any decreases in heat consumption during the drying process will considerably decrease production costs. This study analyzes the high consumption of heat in the drying of baker`s yeast. The main task is to minimize the energy demand and lower the price of the final products with partial heat recovery. These changes will require system modifications. One of the most popular and effective methods that can be used in this case is heat process integration with Pinch Technology. In this study, a reference system was simulated with a mathematical model and analyzed for waste heat streams.This paper suggests the redesigning of a drying system for production of active dry yeast.  Selected streams that satisfy conditions for heat process integration were involved in the evaluation for a better solution. Two different scenarios were proposed as possible solutions. The suggested solutions are retrofit designs of Heat Exchanger Networks. These Heat Exchanger Networks include already installed heat exchangers as well as new heat transfer units. The selection of better design was made with economic analysis of investment. The proposed scenarios of the analyzed sub-system give improvement in heat energy recovery. The best determined solution reduces the cost and thus has the highest profitability, but not the highest heat energy recovery.

Published: June 2019

In this study niobium oxide films were formed without peroxo-precursors from three different mixed acidic aqueous solutions on glassy carbon. Linear sweep voltammetry and potential step were techniques used for electrochemical experiments. The simultaneous and consecutive electrochemical reduction of water, nitrate and sulphate ions provided an alkaline environment with oxygen in the near vicinity of the working cathode, which in combination with the present niobium ions, produced niobium oxides and/or oxyhydroxides on the glassy carbon substrate. The formed deposits were analyzed using scanning electron microscopy and energy dispersive spectroscopy and appear to consist of NbO, NbO2 and Nb2O5. Both the niobium and acid concentration of the electrolytes used influenced the morphology and particle size of the deposits. The formation of niobium-fluoride and hydrogen-niobiumoxide complexes is addressed.
FARM RESPONSE TO CLIMATE CHANGE: EXPLORATORY ANALYSIS OF MACEDONIAN AGRICULTURE USING THE RICARDIAN MODELING APPROACH
Authors: Martinovska Stojcheska Aleksandra , Hristov Jordan , Surry Yves
Published: June 2019

Agriculture is one of most vulnerable sectors in the country, with the imminent intensification of global warming effects. In this paper, we attempt to assess the adaptation of Macedonian crop farmers to the impact of climate change. An alternative specification of the Ricardian model is adopted by using a composite aridity index to capture the re-sponse of farm returns to temperatures and precipitations. The econometric results indicate the significance of winter and summer season weather-related variables and confirm the non-linearity of the climatic function in relation to the farmers’ economic results and adaptation capacity. The farm returns are highly sensitive to different climate change scenarios and tend to decrease unless adequate adaptation and mitigation measures take place, both at micro and macro levels.

Published: June 2019

After the cheese production process, the whey, obtained as a by-product, is not valorised and remains in the waste water which is usually disposed of in natural watercourses. The aim of the study was to analyse the profile of whey proteins, as well as, to quantify the amount of those fractions. 12.5 % SDS-PAGE was used. The total amount of proteins in whey from cow white cheese was 0.73 % ± 0.15, while in cow kashkaval whey was 0.91 % ± 0.08. In whey from white cheese, the relative protein percentages were: lactoglobulin 67.29 % ± 4.99, lactalbumin 20.64 % ± 2.02 and other fractions related to bovine serum albumin with 12.07 % ± 3.05. In whey from yellow cheese, the proteins percent-ages were: lactoglobulin 52.62 % ± 1.21, lactalbumin 17.62 % ± 1.26 and other fractions related to bovine serum albu-min with 29.74 %, respectively. Predominantly, -lactoglobulin was present in the analysed samples. The valorisation of the waste whey obtained in the white cheese production, and development of new product also contributes in the en-vironment protection.
Multi-Loop Magnetisation Based Method for Detecting Coal Mine Wire Rope Defects
Authors: Wang Hongyao , Tian Jie , Bilen Sven , Wu Xinli , Zhou Junying , Meng Guoying , Hua Gang
Published: June 2019

Existing methods for detecting magnetic leakage signals from damaged wire ropes require axial saturation magnetisation, and the accuracy of the detection equipment depends on the saturation degree of magnetisation. Moreover, the expected magnetisation effect is usually difficult to achieve owing to the special characteristics of the rope structure, diameter, and operating environment of the wire rope. Consequently, in addition to other issues, the detection accuracy and versatility of the equipment are low. In this study, a method based on spatial multidimensional orthogonal array loop magnetisation for detecting mine wire rope defects is proposed. Firstly, a new sensor excitation structure model is developed. Then a method of radiant magnetic flux of permanent magnet array is analysed, and the influence law of the number of permanent radiant magnetic blocks on the magnetisation effect is studied. In addition, a method of wire rope detection based on the principle of clustering is investigated, according to which the influence law of the shape, structure, and size of the polyurethane device on the effect of magnetisation is discussed. Finally, through laboratory experiments, the test model and proposed method are verified. The results show that the magnetisation effect is better and more cost-effective when the number of permanent magnet radiation magnetic block is n=8, and the proposed detection method can effectively distinguish damaged wire rope joints. Furthermore, the proposed equipment achieved signal-to-noise ratio of the signals, improving the reliability of damage detection.

Published: June 2019

Backgroud: LGI1(leucine-richanti-glioma1protein) is one of the latest identified voltage-gated potassium channels related antigens. Anti-LGI1 encephalitis affected the limbic systems presenting with subacute onset of progressive neurological, cognitive, psychiatric disturbance and life threatening obstinate hyponatremia. However, Anti-LGI1 encephalitis was mostly considered to be non-malignancy related. The hyponatremia mechanism remains to be elusive. Case presentation: Here we firstly report a 71-year-old female diagnosed of anti-LGI1 encephalitis after renal clear cell carcinoma resection. The old female discovered a renal mass which was identified as renal clear cell carcinoma. Two months after the renal carcinoma resection, the patient fell down frequently and showed discontinuous neuro-psychiatric disorders manifested as memory decline, disorientation, and unintentional upper limb movements as typical faciobrachial dystonic seizure episode. She also had hyponatremia. The combination of her clinical presentations and laboratory assessments supported a diagnosis ofanti-LGI1 encephalitis and renal salt wasting. The Immunohistochemistry studies of the kidney resection indicated circulating LGI1 antibodies in sera might be binding to extracellular LGI1 predominantly in the proximal tubule where the major defect in solute transport exists in renal salt wasting. Conclusion: Anti-LGI1 encephalities with renal carcinoma indicated its paralimbic pathology origin. The early diagnosis and immune-modulation therapy could lead to good outcome. The hyponatremia in anti-LGI1 encephalitis was renal salt wasting instead of syndrome of inappropriate secretion of antidiuretic hormone.
Institutional aspects of educational quality management in higher educational establishments
Authors: Dybach Inna
Published: June 2019

Higher education in Ukraine, as one of the prerequisites for national security and competitiveness of the country, needs to be reformed, first of all in the context of improving the quality of educational services. Educational quality studies have confirmed that the educational system does not adequately address the needs of customers and those who receive education. In this regard, the purpose of the article is to study the theoretical aspects of the institutional provision of the quality management process of higher education. Methods of dialectical cognition, comparative analysis, content analysis and a comprehensive approach to the analysis of transformations in the field of higher education are used in this work. A prerequisite for ensuring the quality of higher education is the definition of the hypostasis of the relevant procedures, among which process, functional and evaluation are identified. It is established in the article that the institutional environment in the field of education is an ordered set of legally established norms and informal rules that determine the conditions for the functioning of institutions of higher education, structure the relationship between the subjects of the educational process and are formed within the educational system. The article deals with a wide network of organizations that form the institutional environment of the national higher education, which, according to the levels of government, are divided into international, national, regional and local. It is noted that state agencies for ensuring the quality of education have the largest share in the formation of the institutional environment of the educational sphere. This often leads to a conflict of interest of stakeholders, which can be solved by the introduction of the Institute of Independent Educational Auditors.
Analysis of risk factors of infant mortality in the case of fetus' Ebstein's
anomaly: results of a multicenter study
Authors: I.V. Komarova , M.V. Medvedev , E.V. Potolova
Published: June 2019

Objectives. To analyze retrospectively the factors of high and low risks of infant mortality in the case of
fetus' Ebstein's anomaly.
Materials. Photos and video materials, and the information from specially designed questionnaires from
the participants of the multicenter study were used. In the paper was presented the comparison of echographic
parameters among 14 fetuses died antenatally and during the first year of life, and among 13 fetuses that survived
during the period of 3 month till 9 years old alive. The ultrasound diagnostics were performed mainly on the
facilities of Voluson hardware (General Electric).
Results. Sensitivity about 100 % and specificity about 100 % to unfavorable prognosis of Ebstein's anomaly
of fetus were in two combinations of 3 parameters: cardiothoracic diameter ratio  0,6 + heart axis (HA) > 60°
+ diameter of pulmonary artery to diameter of aorta (PA/Ao) < 1,0; Celermajer index  0,9 + HA > 70° + ЛА/
Ао < 1,0.
Conclusions. The prenatal diagnosis of Ebstein's anomaly in fetus requires expert detailed echocardiography
to identify and analyze the factors of high and low risks of perinatal and infant mortality. The prognostic risk
factors of infant mortality, discovered in this study, could be recommended for prenatal family consultation and
for the planning of further prenatal care.
Artes de governo, anarqueologia e assinaturas na geração de modelos analíticos no campo da Administração educacional
Authors: Freitas Alexandre Simão
Published: June 2019

O artigo assume a noção de governamentalidade como ferramenta teórica fundamental na análise das categorias que estruturam as teorias administrativas em educação na atualidade. O objetivo consiste em desdobrar metodologicamente uma anarqueologia dos saberes da Administração educacional, seguindo as análises de Michel Foucault e Giorgio Agamben sobre o poder pastoral e a teologia econômica. Como resultado, delineia-se uma leitura alternativa sobre a subsunção recente do conceito de administração pelos paradigmas de gestão no contexto da globalização neoliberal.
Analysis and viability of microturbines in hydraulic networks: a case study
Authors: Rodríguez-Pérez Ángel Mariano , Pulido-Calvo Inmaculada
Published: June 2019

The purpose of this study is to examine the use of hydraulic microturbines to make the most of the hydraulic energy available in pressurized water distribution systems. The study was carried out on suitable points of pressurized hydraulic networks, which are managed by Giahsa, a public enterprise responsible for the management of the municipal communities of services (MAS) in the province of Huelva, southwestern Spain. The distribution system situated between the Cabeza del Pasto reservoir in the Andévalo area (Huelva, Spain) and the wastewater treatment plant (WWTP) in the municipality of Puebla de Guzmán (Huelva, Spain) was examined. To obtain the exact amount of energy which reaches the microturbine, the energy conservation equation considering the loss of energy from friction was used. The results show different locations where it is possible to carry out the installation of a Francis turbine, which can generate an annual energy of approximately 280 MWh per year at the selected point, with an approximate investment cost of €20,000 per year, which means a recovery period of this investment of 2 years.

Cadena global de valor y competitividad de las hortalizas exóticas del estado de Nayarit
Authors: Paredes Medina Reyna Myrna
Published: June 2019

En este artículo se analiza la competitividad de la agroindustria de hortalizas exóticas del estado de Nayarit a través de la estructura de cadena global de valor con énfasis en la gobernanza de la cadena. El objetivo es identificar la oportunidad de escalamiento en la cadena (upgrading) o de ubicarse como un eslabón menos vulnerable que le permita generar y apropiarse de un mayor porcentaje del valor generado en la cadena (Gereffi, Korzeniewicz y Korzeniewicz,1994). Este enfoque permite visualizar la forma como se articula esa agroindustria a una red regional de producción y de comercialización en Estados Unidos y Canadá. La información se obtuvo de cuestionarios y entrevistas a empresarios y funcionarios de instituciones públicas del sector agrícola. En el estudio se detectaron dos tipos de gobernanza predominantes: la cautiva y la jerárquica. Asimismo, se evidencia la importancia de la agroindustria para la región.
Cantos y cantores constructores de identidades en Fray Marcos (Uruguay)
Authors: Scuro Juan
Published: June 2019

En Fray Marcos, pueblo de unos tres mil habitantes ubicado en el límite sur del departamento de Florida, Uruguay, se intentó una aproximación etnográfica a través de los músicos del pueblo como constructores de una identidad local. Teniendo como principal eje de estudio a la producción musical de Fray Marcos, se reflexiona entorno a las relaciones existentes entre estas manifestaciones artísticas, performáticas, constructoras de un sentido compartido por determinados grupos de sujetos y rechazados por otros. Se observa una relativa complejidad en relación a la construcción identitaria del pueblo en su vínculo con la producción musical. Personajes histórico-míticos del lugar se hacen presentes en el canto y constituyen disputas identitarias.
Imágenes e imaginarios urbanos en la “ciudad de las sierras”
Authors: Silva Ana
Published: June 2019

Desde la perspectiva de la Antropología Urbana y con base en un trabajo etnográfico desarrollado en la localidad de Tandil (Buenos Aires, Argentina) en el que se abordó la constitución de narrativas urbanas mediáticas en las interfaces público/privado a partir de la publicación de fotografías familiares en la prensa local, el trabajo se centra en la relación entre imaginarios urbanos, imágenes fotográficas y memoria colectiva a partir de las distintas formas de producción y apropiación social del medio ambiente que aparecían como siendo fuertemente significativas en relación a lo memorable y lo fotografiable en la producción simbólica de la identidad tandilense, en su devenir y sus contradicciones. Se intentará mostrar cómo dicho entorno “natural” es reivindicado y disputado en los imaginarios identitarios locales, adquiriendo una carga valorativa densa, a la vez moral, estética y política.
As Novas Tecnologias e o Campo dos Saberes em Antropologia
Authors: Rocha Ana Luiza Carvalho da
Published: June 2019

A complexidade das formas de conhecimento em Antropologia, para além da problemática da era pós-moderna, adquire um sentido novo quando confrontada com novas tecnologias e suas formas mais integrativas, criativas e interativas de geração de conhecimento, seja enquanto veículo de disseminação da cultura contemporânea, seja como objeto de estudo dos tempos e dos espaços sociais daí decorrentes.Sem dúvida há que dimensionar as recentes descobertas em tecnológica virtual enquanto fenômeno que se integra ao trajeto que instituiu a própria ordem ontológica ou axiológica da estrutura do conhecimento humano, desde seus primórdios, apoiando-se os em estudos já clássicos sobre o assunto.No caso particular da Antropologia, isto significa não a possibilidade do pesquisador empregar tais recursos advindos do desenvolvimento desta técnica e desta linguagem como suporte-ilustração da argumentação de sua experiência “em campo”, mas, principalmente, de aceitar o desafio de gerar novas estruturas narrativas na produção de estudos etnográficos, a partir da exploração de hipertextos que estão para além da escrita alfabética.Tomando como foco central o espaço de problemas que gera, na construção de narrativas etnográficas, a utilização de novas tecnologias, tratarei, aqui de pensar algumas encruzilhadas epistemológicas daí decorrentes, lugar de onde se descortina os horizontes de uma antropologia no cyberspace.
