Published: September 2019

Rannsóknin fjallar um heterósexíska orðanotkun íslenskra framhaldsskólanemenda sem hefur ýmsar birtingarmyndir. Erlendar rannsóknir benda til að orðanotkunin valdi nemendum óþægindum en fáar íslenskar rannsóknir fjalla um efnið. Markmiðið var að skoða tilteknar íslenskar birtingarmyndir orðanotkunarinnar, svo sem notkun orðanna faggi/faggalegt um óviðeigandi hegðun og gay um heimskulega/asnalega hegðun/fyrirbæri. Algengi orðanotkunarinnar var skoðað, kynjamunur, aðstæðurnar sem orðanotkunin fór fram í innan skóla, á netinu og annars staðar samanborið við utan skóla og áhrif orðalagsins á líðan nemenda. Gagna var af lað með spurningalista sem var lagður fyrir nemendur 18 ára og eldri (n=149) í þremur framhaldsskólum með bekkja- eða áfangakerfi á höfuðborgarsvæðinu. Algengi orðanotkunarinnar var misjafnt, transa/tranný yfir trans fólk var sjaldgæfast (5%) en faggi/faggalegt yfir óviðeigandi hegðun var algengast (54%) og því næst kynskiptingur yfir trans fólk (34%). Strákar voru líklegri en stelpur til að hafa notað sum form heterósexísks orðalags. Hærra hlutfall þátttakenda taldi að þeir væru líklegri til að nota heterósexískt orðalag utan skóla en í búningsklefanum, í íþróttatíma eða í skólastofum. Hlutfall þátttakenda sem upplifði óþægindi af að heyra orðanotkunina var misjafnt. Hæst hlutfall þátttakenda upplifði óþægindi af að heyra trukkalessa um stelpu sem hegðaði sér ekki kvenlega (65%), 64% upplifðu óþægindi af að heyra gay yfir heimskulega/asnalega hegðun og 63% af að heyra faggi yfir strák sem hegðaði sér ekki karlmannlega. Fæstir þátttakendur upplifðu óþægindi af að heyra orðið kynskiptingur um trans fólk (32%). Niðurstöður rannsóknarinnar benda til að íslenskir framhaldsskólanemendur noti heterósexískt orðalag í mismiklum mæli en margir upplifi óþægindi af að heyra það. Ef hægt er að draga úr slíku orðalagi gæti það haft jákvæð áhrif á nemendur í námi og í framtíðinni.

Published: September 2019

Kynlífsmenning ungs fólks hefur breyst hratt á undanförnum áratugum. Í greininni er fjallað um upplifun ungra karla af þeirri kynlífsmenningu sem tíðkast í framhaldsskólum nú á dögum. Spurt er hvaða skilning þeir leggja í kynlífsmenninguna, hvaðan hugmyndir þeirra um kynlíf koma, hvort þeir upplifa þrýsting í þessum efnum og hvernig hann birtist. Tekin voru einstaklings- og rýnihópaviðtöl við 11 stráka á aldrinum 18 til 21 árs úr tíu framhaldsskólum á höfuðborgarsvæðinu og utan þess. Fræðileg sjónarmið greinarinnar byggjast á því að kynlífsmenningin hverju sinni móti nokkurs konar kynlífshandrit eða forskrift að hegðun og væntingum. Kynlífshandrit geta verið mismunandi fyrir ólíka hópa og gefa þannig ólík skilaboð eftir því hvaða hópar eiga í hlut. Þannig eiga strákar og ungir karlar gjarnan að vera virkir kynferðislegir gerendur og mikil reynsla á kynlífssviðinu þykir eftirsóknarverð. Stelpur á hinn bóginn eiga að halda sig innan ákveðins ramma og takmarka fjölda bólfélaga, annars eiga þær á hættu að fá á sig druslustimpil. Niðurstöður benda til þess að félagsþrýstingur hafi töluverð áhrif á kynlífsmenningu ungra karla. Mikill þrýstingur er á þeim að vera ávallt reiðubúnir að stunda kynlíf og helst að deila þeirri reynslu með kunningjahópnum. Klám hefur mikil áhrif á hugmyndir þeirra um hvers er vænst af þeim í kynlífi og reyna þeir margir hverjir að standast þær væntingar. Þá telja þeir að mismunandi reglur gildi um kynhegðun karla og kvenna og að strákum leyfist meira í kynferðislegum efnum. Enda þótt stór hluti stráka taki þátt í ríkjandi kynlífsmenningu reynist hún mörgum þeirra erfið og kvíðavaldandi.

Authors: Dodge Lynn E. , Koontz Stephen R. , Hadrich Joleen C.
Published: September 2019

OBJECTIVE

To identify factors associated with financial performance of independently owned companion and mixed animal veterinary practices.

SAMPLE

Financial statements (ie, annual balance sheets and income statements for 3 consecutive years) were obtained from 45 practices.

PROCEDURES

Ratio analysis of financial statements was performed with the DuPont Model, and practices were grouped into 4 financial performance groups on the basis of return on equity. Liquidity and solvency ratios and debt management and asset investment practices were then compared among financial performance groups

RESULTS

Financial liquidity was low across all financial performance groups, but most practices were solvent, with assets exceeding liabilities. Debt management was found to be a limiting factor for financial success, with lower-performing practices using credit cards and lines of credit to purchase capital assets. Practices that were not solvent owed debts on the purchase of intangible assets and had higher owner withdrawals, compared with other practices. Practices that built productive capacity by borrowing and investing in productive assets had higher long-term returns.

CONCLUSIONS AND CLINICAL RELEVANCE

Results suggested that proper debt management coupled with prudent asset investment was associated with higher financial performance for independently owned companion and mixed animal veterinary practices.

OBJECTIVE

To describe the clinical findings and short-term outcomes for rabbits with signs of gastrointestinal tract dysfunction or rabbit gastrointestinal syndrome (RGIS).

ANIMALS

117 client-owned rabbits.

PROCEDURES

The electronic medical records database of a veterinary teaching hospital was searched to identify rabbits that were examined because of altered or absent food intake and decreased or absent fecal output between June 1, 2014, and June 30, 2016. For each rabbit, information extracted from the record included history of prior episodes of gastrointestinal tract dysfunction, signalment, physical examination and diagnostic test results, and outcome.

RESULTS

117 of the 484 (24%) rabbits examined at the hospital during the study period met the inclusion criteria and were enrolled in the study. Fifty-nine and 58 rabbits were managed on an inpatient and outpatient basis, respectively. Gastrointestinal stasis without overt obstruction was diagnosed for 43 rabbits on the basis of abdominal radiographic, ultrasonographic, or necropsy results. Many rabbits had concurrent disease and biochemical abnormalities. Fifteen, 18, and 84 rabbits died, were euthanized, and survived to hospital discharge, respectively. Rabbits that were hypothermic (rectal temperature, ≤ 36.6°C [97.9°F]) during the initial examination were 5 times as likely to die or be euthanized as were euthermic rabbits, after controlling for potential confounders.

CONCLUSIONS AND CLINICAL RELEVANCE

Results indicated that the prognosis was generally good for rabbits with signs of RGIS unless they were hypothermic during initial examination. Prospective studies are warranted to further elucidate and characterize RGIS and assess the efficacy of various treatments and outcomes for affected rabbits.

Published: September 2019

The influence of confined optical phonons on the Hall Coefficient (HC) in a Cylindrycal Quantum Wire (CQW) with an infinite potential (for electron – confined optical phonons scattering). Consider a case where CQW is placed in a perpendicular magnetic field , a constant - electric field  and an intense electromagnetic wave . By using the quantum kinetic equation for electrons interacting with Confined Optical Phonon (COP), we obtain analytical expressions for (HC), which are different from in comparison to those obtained for the HC in the case of normal bulk semiconductor and in the case of cylindrycal quantum wire with electron – unconfined phonons scattering mechanism. Numerical calculations are also applied for AlGaAs/GaAs/AlGaAs cylindrycal quantum wire, we see the HC depends on magnetic field B, temperature T, frequency Ω and amplitude E0 of laser radiation and especially quantum index m1 and m2 characterizing the phonon confinement. This influence is due to the quantum index m1 and m2, which makes an increase of Hall coefficient by 2,3 times in comparition with the case of unconfined phonons. When the quantum number m1 and m2 goes to zero, the result is the same as in the case of unconfined phonons.

Authors: Kien Pham Huu , Mai An Pham , Hong Linh Nguyen , Thuy Trang Giap
Published: September 2019

The FeB nanoparticle consisting of 5000 particles (4500 Fe atoms and 500 B atoms) have been investigated by means of molecular dynamics (MD) simulation. When the amorphous FeB nanoparticle is annealed at temperature of 900 K for a long time, it is crystallized into bcc crystalline structure. The simulation shows that the sample undergoes crystallization via the nucleation mechanism. During the crystallization, B atoms diffuse to the boundary region of Fe crystal. The crystal growth proceeds when this boundary region attains specific properties which are defined by the fraction of B atoms and the energies of AB-atoms and CB-atoms. Further our study indicates that the crystalline and mixed FeB nanoparticles consists of three distinct parts including Fe crystalline and two FeB amorphous parts (B-poor and B-rich amorphous part). The different polymorphs of FeB nanoparticle differs in the local structure, size of Fe crystal and energies of different type atoms.

Authors: Van Dat Nguyen
Published: September 2019

In Discretized Kaluza-Klein theory (DKKT) the gauge fields emerge as components of gravity with a single coupling constant. Therefore, it provide a new approach to fix the parameters of the Standard Model, and in particular the Weinberg angle. We show that in our approach using DKKT, the predicted value of Weinberg angle is exactly the one measured in the electron-positron collider experiment at Q = 91.2 GeV/c. The result is compared with the one predicted the group theoretic methods.
Distribution of Sodium and Diffusion Mechanism in Sodium Silicate Liquid
Authors: Thi Thanh Ha Nguyen
Published: September 2019

Molecular dynamic simulation is employed to study the structural properties and diffusion mechanism in sodium silicate (Na2O.4SiO4). Structural characteristics are clarified through the pair radial distribution function, distribution of SiOx coordination units, network structure. The simulation results reveal the structure of Na2O.4SiO4 liquid consists of one Si-O network that is mainly formed by SiO4 units. The spatial distribution of sodium is non-uniform; sodium tends to be in the non-bridging oxygen-simplexes and in larger-radius simplex. Moreover, the sodium density for non-bridging oxygen region is significantly higher than the one for other region. Further, we find that Si and O diffuse by bond break-reformation mechanism, while the motion of Na consists of two parallel processes. Firstly, Na atoms hop from one to another O within a disordered network where each bridging oxygen (BO) has one site, while a non-bridging oxygen (NBO) possesses two sites. The average resident time for Na staying near NBO is much longer than that near BO.

Published: September 2019

Abstract: In this research, the nonlinear dynamic response of functionally graded carbon nanotube reinforced composite (FG-CNTRC) sandwich annular spherical shells supported by Pasternak’ foundation is considered by using the analytical approach. Unlike existing works, the structure has three layers: FG-CNTRC layer – homogeneous core – FG-CNTRC layer. Several examples are considered to analyse the behaviour of this sandwich-structured composite. The classical shell theory (CST) is used to derive theoretical formulation delineating nonlinear dynamic response of FG-CNTRC sandwich annular spherical shells. The numerical results explain the effect of material, geometrical parameters, and elastic foundations on the nonlinear dynamic response of the annular spherical shell.

Meanings in the Digital Age. Homo Singularity
Authors: Volnov Ilya N.
Published: September 2019

The paper approaches the techno-humanitarian balance of physical (accelerating) and humanitarian (controlling) technologies. It demonstrates that the absence of the human in this ba­lance makes the idea about ensuring the socio-system’s sustainable development through the establishment of techno-humanitarian balance erroneous. The required adequate proportion of “powers” between the technologies in the techno-humanitarian balance necessitates the civilization to attempt to “harness” not only the technological singularity but the humanitarian singularity, too. It is shown that the techno-humanitarian balance in the singularity mode destroys the human physical and mental nature. The human is introduced into the binary technological balance through transforming it into a triple balance and adding the semantic technologies inherent to human beings. The triple balance is characterized by the oppositions between intelligence and thinking, information and meanings. The paper explores the triple balance and its edges in the context of the ultimate singularity. It is shown that the human being, through thinking and meanings, can correlate themselves with the semantic singularity (the infinity of the semantic field) — thus becoming Homo Singularity. These conclusions are substantiated through the V.V. Nalimov’s probabilistic model of consciousess, which also mathe­matically formalizes the process of semantic decapsulation of the personality and the personal interaction with the semantic vacuum (infinity).

The paper introduces the concept of finite dilatation of the cultural semantic field and the big semantic transition as the era of formation of Homo Singula­rity and beginning of their practical work with semantic infinity. The paper provides examples of such practical work in the fields of art and science. Homo Singularity not only prevents their physical and mental nature from destruction but also keeps the po­werful artificial intelligence under control by counte­ring big data with their ability to integrate the multiple into the single (whole) and make a transition from the discrete level of information to a continuous (infinite) level of meanings.
Theaters in the Mirror of Statistics: Facts Instead of Myths
Authors: Muzychuk Valentina Yu.
Published: September 2019

The article attempts to debunk, in the public consciousness, some myths related to the econo­mic component of theatrical activity. The question is about the substitution of the concepts of self-sufficiency and financial and operating independence of the theatre, the policy to “earn more”, and the assessment of theatre activity effectiveness from the perspective of business approach and requirements of constant increase in attendance.

Basing on the analysis of statistical data, the article studies the structure of financial receipts of theatres. The results show the impossibility of functioning of the Russian repertoire theatre on the principles of self-sufficiency, in which the theatre’s own expenses should be covered by earned income. Russia, which has a provision index of 4.2 theatres per 1 million inhabitants (2017), lags behind foreign countries, and in more than half of the constituent entities of the Russian Federation, it is lower than the average Russian index. The thesis that there are many theatres in Russia is refuted by the results of statistical data analysis and international comparisons. The hopes that private theatres can become a serious competitor and substitute for state theatres in Russia are not supported by real practice. Large metropolitan theatres have long reached the limit of attendance at the level of 99%. Low attendance is not always an indicator of the theatre’s inefficiency, and the low living standard does not allow people to go to the theatre as often as they would like. Finally, it is not possible to demand 40-year-old attendance indicators from the theatre, because the possibilities for leisure activities have drastically expanded, including through the development of information and communication technologies. The task solution of increasing the atten­dance of theatres does not lie in the direction of the policy of 100% occupancy of the auditorium, but requires serious investments in the touring activities and infrastructure of the host party.

The article shows that the erroneous decisions put into the practice of making managerial decisions are counterproductive because they contradict the nature of the theatre and the development laws of the eco­nomy of culture as a whole.
Designing Heterogeneous Catalysts for Renewable Catalysis Applications Using Metal Oxide Deposition
Authors: Du Yuan-Peng , Luterbacher Jeremy S.
Published: September 2019

Heterogeneous catalysis has long been a workhorse for the chemical industry and will likely play a key role in the emerging area of renewable chemistry. However, renewable molecule streams pose unique challenges for heterogeneous catalysis due to their high oxygen content, frequent
low volatility and the near constant presence of water. These constraints can often lead to the need for catalyst operation in harsh liquid phase conditions, which has compounded traditional catalyst deactivation issues. Oxygenated molecules are also frequently more reactive than petroleum-derived
molecules, which creates a need for highly selective catalysts. Synthetic control over the nanostructured environment of catalytic active sites could facilitate the creation of both more stable and selective catalysts. In this review, we discuss the use of metal oxide deposition as an emerging
strategy that can be used to synthesize and/or modify heterogeneous catalysts to introduce tailored nanostructures. Several important applications are reviewed, including the synthesis of high surface area mesoporous metal oxides, the enhancement of catalyst stability, and the improvement
of catalyst selectivity.
Computationally Generated Maps of Surface Structures and Catalytic Activities for Alloy Phase Diagrams
Authors: Cao Liang , Niu Le, , Mueller Tim
Published: September 2019

To facilitate the rational design of alloy catalysts, we introduce a method for rapidly calculating the structure and catalytic properties of a substitutional alloy surface that is in equilibrium with the underlying bulk phase. We implement our method by developing a way to generate surface cluster expansions that explicitly account for the lattice parameter of the bulk structure. This approach makes it possible to computationally map the structure of an alloy surface and statistically sample adsorbate binding energies at every point in the alloy phase diagram. When combined with a method for predicting catalytic activities from adsorbate binding energies, maps of catalytic activities at every point in the phase diagram can be created, enabling the identification of synthesis conditions likely to result in highly active catalysts. We demonstrate our approach by analyzing Pt-rich Pt–Ni catalysts for the oxygen reduction reaction, finding two regions in the phase diagram that are predicted to result in highly active catalysts. Our analysis indicates that the Pt3Ni(111) surface, which has the highest known specific activity for the oxygen reduction reaction, is likely able to achieve its high activity through the formation of an intermetallic phase with L12 order. We use the generated surface structure and catalytic activity maps to demonstrate how the intermetallic nature of this phase leads to high catalytic activity and discuss how the underlying principles can be used in catalysis design. We further discuss the importance of surface phases and demonstrate how they can dramatically affect catalytic activity.
Catalytic Asymmetric Radical-Polar Crossover Hydroalkoxylation
Authors: Discolo Christopher , Touney Eric , Pronin Sergey
Published: September 2019

Asymmetric intramolecular hydrofunctionalization of tertiary allylic alcohols is described. This metal hydride-mediated catalytic radical-polar crossover reaction delivers corresponding epoxides in good to high enantioselectivity and constitutes the first example of asymmetric hydrogen atom transfer-initiated process. A series of modified cobalt salen complexes has proven optimal for achieving good efficiency and asymmetric induction. Experimental data suggest that cationic cobalt complexes are involved in enantio-determining step, where cation–π interactions in the catalyst contribute to the asymmetric induction.
Band Alignment and Charge Transfer in CsPbBr3-CdSe Nanoplatelet Hybrids Coupled by Molecular Linkers
Authors: Dey Swayandipta , Cohen Hagai , Pinkas Iddo , Lin Hong , Kazes Miri , Oron Dan
Published: September 2019

Controllable interface characteristics are demonstrated at the nanoscale, using two types of semiconducting nanoparticles with nearly identical optical band gaps, CsPbBr3 nanocrystals and CdSe nanoplatelets, capped with molecular linkers. By exploiting chemical recognition of the capping molecules, the two types of nanoparticles are brought into mutual contact, thus initiating spontaneous charge transfer and the formation of a strong junction field. Depending on the choice of capping molecules, the magnitude of the latter field is shown to vary in a broad range, corresponding to an interface potential step as large as circa 1 eV. The band diagram of the system, as well as the emergence of photo-induced charge transfer processes across the interface are studied here by means of optical and photoelectron based spectroscopies. Our results propose an interesting template for generating and harnessing internal built-in fields in heterogeneous nanocrystal solids.

Published: September 2019

The Indian tourism and hospitality industry has emerged as one of the key drivers of growth among the service sector in India. As the growing sector the demand of labor is also high. Students from hospitality colleges are invited by the hotels for outdoor catering when demand of the business is more to support the operation. Many students prefer going for outdoor catering and it has significant role to improve their practical skills. The exposure will help them for their career growth as they get clarity about services and boost their confidence level. Late working hours and payment need some changes to increase the number of outdoor catering. Providing transport facility for all the students will also have positive impact on the student’s frequency to go for outdoor catering. Students feel outdoor catering to be made mandatory which will help each individual to develop.

Authors: Ali Mohamed Ahmed
Published: September 2019

The hotel industry is often suffering from price wars, which have a number of reasons such as financial crises. Resulting from these reasons are going to reduce prices. The continued price reductions among hotels, resulting in price wars. So, this paper searches for developing and empirically testing a framework to examine which factors causes the price wars and the consequences of them. Using SEM to examine the data collected from a sample of 113 hotels, the results indicate supply, financial crises, pricing objectives based on discounts, and price sensitivity have a significant positive impact on price wars’ eruption. Price wars have a significant negative influence significantly on hotel profitability, hotel image, competitive position, brand loyalty. On the other hand, price wars may lead to exit from market. The results offer important implications for hoteliers and are likely to stimulate further research in the area of pricing.

A Study on the Effect of Individual Career Development Activity on the Career Satisfaction
Authors: Oh Jong-Ryul , Kim Eun-Woo , Jang Jung-Ok
Published: September 2019

This study is to suggest implications for individual career development activities. The questionnaire was distributed and collected among 305 people who have had more than one career development activity. The collected data verified the adequacy of the structural equation modeling and its cause-and-effect relationship to each concept. Social networks, hobbies, and acquiring the certificates do not show any significant relationship to career development, but achievement has a significant effect on it. It was found that two jobs have a significant effect on both career development and sense of achievement. It said that career development and sense of achievement have a significant effect on career satisfaction. Since career development and sense of achievement both effect career satisfaction while social networks, hobbies, and acquiring the certificates have a significant impact only on sense of achievement, the main implication of this study is that, by linking the above variables to career development, it is necessary to strengthen the compensation system and support measures that can induce career development in order to improve career satisfaction ultimately. It gives directions to those who want to develop activities.

شعر الحكمة عند يحيى بن الحكم الغزال
Authors: SHUKUR Goran Salahaddin
Published: September 2019

التعبير

عن الحياة والفلسفة والحكمة في القصائد لايمنع الشاعر من الحديث عن كل ما هو غريب

من تصور الإنسان للتعقيد المادي للحياة مع الإكثار من مخاطبة العقل وتحكيم المنطق

عند تقديمه للحلول الاجتماعية في قصائده المختلفة, على الخصوص التي تتناول النقد

الاجتماعي. فالبعد الحقيقي والعميق لقصائده الفلسفية تتضح في كثير من الأحيان

عندما يقدم الشاعر على معالجة مشاكل المجتمع. وأنَّه كان صريحاً وواقعياً وصادقاً

في اعترافاته. ولقد جعل كل خبراته في الحياة والمجتمع في مجموعة من قصائده الزهدية

التي نظمها في المرحلة الثالثة من حياته. و يمكن أن نقول أن الشعر كان يمثل الحياة

الحقيقي للغزال ولقد أصبح يجمع بين هموم الذات وهموم

الجماعة ، يروم كشف الواقع واستشراف المستقبل متنقلا من التفسير إلى التغيير.

وبمعنى آخر، لقد أصبح وعي الشاعر بالذات وبالزمن وبالكون مرتبطا بوعيه بالجماعة،

ومتضمناً له. وماكان لشيء من ذلك أن يحدث لولا وعي الشاعر بالحياة وفلسفة العيش

والتعايش التي يرمز إليها برمز واحد، ذي طابع شمولي، هو رمز الموت الذي يعني موت

الذات وموت الزمن الماضي بكل أمجاده والحاضر بكل تطلعاته سيما وإن الصراع بين

الموت والحياة في تجربة الشاعر  يعني في

آخر الأمر الصراع بين الحرية والحب والتجدد، وبين الحقد والاستعباد والنفي من

المكان ومن التاريخ.

Published: September 2019

Con datos de una encuesta realizada a los compradores de la Feria Agroecológica de “La Carolina”, estetrabajo analiza los determinantes socioeconómicos del consumo de productos agroecológicos en Quito. Losresultados de análisis descriptivos y multivariados indican el bien personal (salud) es la principal (única) motivaciónpara el consumo de alimentos agroecológicos. Si bien este hallazgo es consistente con estudios previosrealizados en países de Europa y Norteamérica, los resultados de este estudio también reflejan que criteriosrelacionados con el bien social (la sustentabilidad de la producción agrícola, la protección del medio ambiente,el bienestar de los pequeños productores y la seguridad y soberanía alimentaria) no tienen ninguna incidenciaen las decisiones de consumo de productos agroecológicos.

El objetivo de este estudio fue el de evaluar el comportamiento agronómico de híbridos de maíz en tres diferentes localidades de la Costa ecuatoriana. Se evaluaron 5 híbridos: dos locales (INIAP H-551 e INIAP H-601), dos extranjeros (Insignia 105 y S-505) y uno experimental (UTEQ). Se utilizó un diseño de Bloques Completos al Azar con 5 tratamientos en 4 repeticiones y pruebas de Tukey al 95% de probabilidad para establecer las diferencias entre las medias de los tratamientos. Los resultados indican que la zona de estudio no tiene ninguna incidencia en las variablesdependientes evaluadas. El híbrido experimental UTEQ fue el más precoz con 49.8 días a la floración masculina, mientras que el híbrido S-505 fue el más tardío con 53.6 días a la floración masculina. El hibrido INIAP H-551 presentó las mazorcas de menor longitud con 15.5 cm, mientras que las de mayor longitud las produjo el híbrido UTEQ. El híbrido S-505 presentó las mazorcas con mayor número de hileras de granos (17.4), mientras que INIAP H-551 con un promedio de 13.3, mostró el menor número de hileras de granos. El híbrido UTEQ registró un rendimientopor encima de los dos híbridos del INIAP alcanzando un promedio de 6852 kg/ha entre las tres zonas, siendo los híbridos Insignia 105 y S-505 los más productivos con 8336.4 y 8151.6 kg/ha, respectivamente. En términos económicos, el híbrido UTEQ presentó una rentabilidad de entre 75 y 81 %, por lo cual se concluye que este material genético puede ser destinado a pequeños productores, dado que demanda menores gastos por unidad de producción.

Published: September 2019

La determinación precisa de los coeficientes del tanque evaporímetro Clase A permiten estimar la evapotranspiración de referencia y obtener valores reales de necesidades hídricas de los cultivos. Se utilizó información climatológica diaria y mensual para el análisis del coeficiente del tanque (Kp) y de la evapotranspiración de referencia (ETo). Los métodos utilizados para determinar Kp fueron: Allen – Pruitt, Cuenca, Pereira, Snyder y el coeficiente calculado. Se determinaron los parámetros inferenciales para el análisis cruzado entre los diferentes métodos para estimar ETo: error medio absoluto, coeficiente de concordancia y el coeficiente de determinación. Los resultados demuestran que: i) para información climatológica diaria, el contraste entre los métodos Allen – Pruitt y Snyder presentó los índices inferenciales de mayor precisión; ii) para información del clima mensual, el contraste Snyder – Coeficiente calculado presentó índices de mayor precisión, siendo 0.72 el coeficiente Kp promedio; iii) la máxima ETo promedio se registró en el mes de agosto con 139.32 mm y la mínima en abril con 76.54 mm. Las conclusiones principales son: i) los métodos Snyder y el coeficiente calculado pueden utilizarse para determinar el coeficiente Kp para información climatológica mensual y el método Snyder para información diaria y ii) el método estándar Penman Monteith FAO 56 presentó índices inferenciales bajos para información climática diaria y de mayor precisión para información promedio mensual, considerando el entorno agroecológico del valle de Tumbaco.

Se debe comenzar a concebir el voluntariado, en el desarrollo de la actividad turística comunitaria, como una oportunidad de mejora económica, ganancia organizativa en el aspecto cultural y social, y por tanto, en el nivel de vida de los involucrados. El trabajo del voluntariado en el desarrollo del turismo comunitario aportaría ganancias sustanciales a las comunidades que lo practiquen. En esta investigación de enfoque cuali-cuantitativo, de tipo descriptiva analítica-exploratoria, se propuso como objetivo valorar el tema del voluntariado mediante el análisis de voluntarios turísticos que han trabajo el turismo comunitario en el Ecuador, para la implementación de un programa de voluntariado como herramienta de desarrollo del turismo comunitario en la parroquia Tocachi, del cantón Pedro Moncayo. Después de dicha valoración se concluyó que, se debe instaurar un voluntariado abierto y participativo, interclasista, intercultural e intergeneracional, donde todos aporten y se beneficien. El mismo aporta en cuatro ejes al desarrollo del turismo comunitario, la cultura, organización, ambiente y economía, en esta última puede contribuir al aporte económico en las comunidades que realicen el turismo comunitario. El proyecto de voluntariado como herramienta de desarrollo para el turismo comunitario en la parroquia de estudio es viable y realista para aportar ventajas económicas a esa comunidad. Además, existen carencias de datos sólidos sobre el voluntariado que la comunidad académica y el Estado deben garantizar para desarrollar de estrategias que tengan en cuenta la fuerza universal y poderosa que representa el voluntariado en el desarrollo del país.
