El método de experto en tesis doctorales cubanas del ámbito educacional: un estudio bibliométrico y de contenido / The expert method in Cuban doctoral dissertation in the educational field: a bibliometric and content study

La presente investigación tiene como objetivo caracterizar la evolución y empleo del método de experto en investigaciones pedagógicas y educacionales cubanas. Para cumplir este propósito se desarrolló un estudio bibliométrico y de contenido, con una muestra conformada por 1000 tesis doctorales defendidas durante el período 1995-2019, lo cual representa el 31,96 por ciento de la producción nacional en estas ramas de la ciencia. Se identificaron 29 métodos de uso más frecuente, así como una red de términos que demarcan cinco conglomerados de campos de aplicación. Los métodos se clasifican, generalmente, como empíricos o teóricos, con un grado de normalización relativamente bajo. En particular, el método de experto ha sido aplicado de manera creciente y sistemática durante las dos últimas décadas, con énfasis marcado en el caso particular del método Delphi. Las terminologías más comunes son experto y especialista, sin que se aprecien diferencias conceptuales notables entre ellas. La búsqueda de validez ha sido sustituida paulatinamente por otras nociones cualitativas como viabilidad y el binomio pertinencia-factibilidad. La búsqueda de consenso ha perdido terreno frente a otros objetivos más flexibles, como la evaluación de la calidad de un resultado científico, principalmente metodologías, concepciones y modelos. También se estableció un modelo matemático basado en la regresión logística binaria, que resulta útil para estimar la probabilidad de que el método de experto se implemente durante una investigación doctoral. En este modelo intervienen siete variables, entre las cuales la encuesta y los métodos estadísticos resultan más influyentes e interrelacionados(AU)

The objective of this research is to characterize the evolution and use of the expert method in Cuban pedagogical and educational research. To fulfil this purpose, a bibliometric and content study was developed. A sample was made up of 1000 doctoral dissertations from 1995-2019, which represents 31.96percent of the national production in these branches of science. Twenty-nine most frequently used methods were identified, as well as a network of terms that define five conglomerates of application fields. Methods are generally classified as empirical or theoretical, with a relatively low degree of standardization. In particular, the expert method has been applied increasingly and systematically during the last two decades, with marked emphasis on the particular case of Delphi method. The most common terminologies are expert and specialist, with no notable conceptual differences between them. The search for validity has gradually been replaced by other qualitative notions, such as feasibility and pertinence-feasibility binomial. The search for consensus has lost ground compared to other more flexible objectives, such as the evaluation of the quality of a scientific result, mainly methodologies, conceptions and models. A mathematical model based on binary logistic regression was also established, which is useful to estimate the probability that the Expert Method is implemented during a doctoral research. Seven variables are involved in this model, among which the survey and statistical methods are more influential and interrelated(AU)

Investigation Report of Chinese Medicinal Materials Artificial Planting in Lanzhou City / 中国药房

OBJECTIVE： To provide reference for promoting large-scale， standardized and high-quality planting of Chinese medicinal materials. METHODS： Through the communication by phone with the agriculture bureau of each district and county， the contact with the relevant township government and the field visit investigation during Jun. 2013-Dec. 2018 by Lanzhou institute for food and drug control， variety， area， yield and output value， cultivation techniques and processing methods of Chinese medicinal materials in the planting area of Lanzhou were investigated and statistically analyzed. The advantages and problems were analyzed， and reasonable suggestions for planting Chinese medicinal materials were put forward. RESULTS & CONCLUSIONS： In 2018， artificial planting of Chinese medicinal materials in lanzhou has a certain scale， with 21 artificial planting varieties， a total planting area of about 510 000 mu， an annual output of 170 000 tons， an annual production value of over 1.7 billion yuan. Cultivation techniques mainly include seedling transplanting， mulching or direct seeding， while drying is the main processing method. Artificial planting of Chinese medicinal materials in Lanzhou has a certain scale and prominent characteristic varieties； authenticity is guaranteed， and the combination of Chinese medicinal materials planting and tourism drives economic development. However， there are still some problems， such as a certain distance from the development of industrialization， variety degradation， backward basic research， serious natural disasters. It is suggested to strengthen its propaganda and expand its advantages， at the same time， enhance government support， develop and construct planting bases of Chinese medicinal materials， strengthen the awareness of good agricultural practice （GAP）， strengthen scientific research strengeh， explore breeding techniques of fine varieties of Chinese medicinal materials， develop insurance of Chinese medicinal materials， and guarantee the development of planting industry so as to promote large-scale， standardized and high-quality planting of Chinese medicinal materials.
