Scale of Teaching Strategies for Collaborative Learning: Design, Validation and Evaluation of Its Psychometric Properties in High School Education  [PDF]
Magaly Cárdenas Rodríguez, Luz Marina Méndez Hinojosa, César Alejandro Ortiz Páez
Psychology (PSYCH) , 2019, DOI: 10.4236/psych.2019.102019
Abstract: Most of the educational programs worldwide have focused on the diverse competences of the students, but in all of them, collaborative learning plays an important role. It is likely that many institutions are unaware of the teaching strategies that can produce collaborative learning in the classroom. Therefore, the present study aimed to design and evaluate the psychometric properties of a scale that examined the frequency of use of teaching strategies that led to collaborative learning in students. Nine subscales were designed, each one measuring a different strategy, these were evaluated by expert judgment and subsequently, they were applied to a sample of 200 high school teachers. Based on the data obtained, it is possible to provide evidence, through exploratory factor analysis and Cronbach’s alpha, of the instrument’s validity and reliability.
Cardenalización del índice de marginación: una metodología para evaluar la eficiencia del gasto ejercido en el Ramo 33
Cárdenas Rodríguez, óscar Javier;
EconoQuantum , 2010,
Abstract: the deprivation index developed by the national population council is an ordinal measure indicating the degree of exclusion from the enjoyment of economic development experienced by regions (states, municipalities and towns). this indicator is widely used, among other things, to target programs to combat poverty. however, due to the methodology used in its construction, the index can not be used to evaluate the effectiveness of some government programs aimed at reducing the social gap. in this paper a methodology for the "cardenalización" of the index is proposed. it transforms the original index into a cardinal measure in such a way that it can be employed to quantify the improvements and setbacks in the level of welfare of different areas of the country. additionally, the technique is applied to evaluate the effects of ramo 33 transfers in changes of marginalization at the state level.
Utilización del modelo de esquemas cognitivos de base (SCB) para la confirmación del núcleo de una representación social: Análisis del movimiento antiglobalización
Cárdenas, Manuel;Rodríguez, Roberto;
Psicologia & Sociedade , 2006, DOI: 10.1590/S0102-71822006000300016
Abstract: in this paper we used a method for the corroboration of the central core of a social representation based on an adaptation of the model of basic cognitive schemes. we have worked on the data from a previous study on social representation of the anti-globalization movement. this research seeks to determine if the most relevant quantitative elements are, simultaneously, those of greater connectivity (qualitative relevance). it also seeks to analyze the type of connections established between these central elements (on the base of the five families of schemes specified by the theory of scb and its corresponding connectors) and the concepts associated to these stimuli.
Regla Fiscal para Determinar el Monto del Subsidio Estatal a la Universidad de Guanajuato Regla Fiscal para Determinar el Monto del Subsidio Estatal a la Universidad de Guanajuato
Oscar Javier Cárdenas Rodríguez
Acta Universitaria , 2012,
Abstract: En este trabajo se propone una contribución especial y una regla fiscal para que el gobierno estatal determine, ex ante, el monto de subsidio ordinario que ha de otorgar cada ejercicio fiscal a la Universidad de Guanajuato. La ventaja de este mecanismo es la eliminación de la negociación presupuestal que se realiza a o con a o entre la Universidad, el Gobierno Estatal y el Congreso Local. An additional tax and a fiscal rule is proposed, in this paper, so that the Local Government determines, ex ante, the ordinary public subsidy it should give each fiscal year to the Universidad de Guanajuato. The advantage of this mechanism is the elimination of the budget negotiation that takes place yearly between the Universidad, the Local Government and the State Congress.
Medidas de Bienestar: De lo General a lo Particular Medidas de Bienestar: De lo General a lo Particular
Oscar Javier Cárdenas Rodríguez
Acta Universitaria , 2012,
Abstract: En este artículo se analizan medidas de bienestar. Se inicia por el producto interno bruto como un indicador a nivel nacional y, al tiempo que éste se analiza, se explican algunas medidas alternativas a nivel agregado, como el PIB ecológico y el índice de desarrollo humano. Después se analizan algunas medidas de carácter microeconómico, como la distribución del ingreso, medidas de pobreza y marginación. Este análisis concluye indicando que la mejor medida de bienestar depende del objetivo específi co que se busque analizar, ya que ninguna medida puede dar respuesta a todas las preguntas relacionadas bienestar. This paper analyzes ways of measuring well-being. The study begins with the gross domestic product (GDP) as a measurement of well-being at the national level. It also discusses alternative ways of measuring well-being at the level of aggregates, such as the ecological GDP and the index of human development (HDI). Moreover, some measurements of the microeconomic type, such as income distribution, poverty, and marginalization are analyzed. This research study states that the best indicator of welfare depends on a given specific objective. This is because none of the ways of measuring well-being is able to provide a definite answer to all the questions related to the welfare of a society.

Métodos alternativos en la conservación de Trichoderma harzianum Rifai
Rodríguez Batista,Dayamí; Gato Cárdenas,Yohana;
Fitosanidad , 2010,
Abstract: conservation of trichoderma harzianum rifai a-34 strain, used in mass production, was evaluated stored in silica gel, distilled water and under mineral oil. viability, morphological characters and antagonist capacity had been evaluated for one year. samples conserved in sterile distilled water and under mineral oil showed no differences from the original culture stored in potato dextrose agar at 40 c, while those conserved in silica gel were viable for three months only.
Da?os en germoplasma de cebada (Hordeum vulgare Lin.) producidos por Rhyzoperta dominica FABRICIUS
Cárdenas,Regla M; Ortiz,R; Rodríguez,Odile;
Cultivos Tropicales , 2009,
Abstract: quantitative damages caused by stored pests are vitally important to seeds destined for investigation, since there are generally very small amounts. the study was carried out in seeds from 96 syrian barley lines preserved for six months at 15 + 2oc, with the objective of knowing this sort of losses provoked by rhyzoperta dominica f.; thus, weight reduction (g) was considered, 1000-grain weight (pmg) was determined, the number of adult insects in 1000 grains (namg) was estimated and attack index (ia) was also calculated. results showed that 12 lines were damaged by r. dominica, with an average weight (g) loss of 18 %; the lines studied showed a low pmg (32.38 g), whereas the estimated namg was of 31.25 and ia of 3.17 %.
Sobre la pertinencia de las categorías culturales en la elaboración de las Representaciones de los Nuevos Movimientos Sociales
Castro, Manuel Cárdenas;López, Roberto Rodríguez;
Psicologia & Sociedade , 2007, DOI: 10.1590/S0102-71822007000300012
Abstract: this paper presents a study of the social representations on the anti-globalization movement (agm) elaborated from a sample of spanish workers. a method of free association of words as stimuli and an image of movement survey (that takes the form of a semantic differential) were used for the analysis of these representations. the results obtained by free association of words were analyzed by multivariated methods (hierarchical cluster analysis, multidimensional scaling and correspondences analysis). the results on the image survey were summarized in seven principal factors. the averages of these factors were compared according to the criterion of political self-categorization. the principal effect observed was a rejection, from a part of the subjects of the sample, in using the cultural categories that in other studies appeared as the most pertinent fo the elaboration of social representations about the anti-globalization movement (amg).
Uso de 600 mg de Misoprostol para inducir el aborto temprano

Revista Cubana de Obstetricia y Ginecolog?-a , 2003,
Abstract: the objective of this study was to evaluate the efficacy and safety of the self-administration of 600mg of misoprostol by the vaginal route up to three doses every 8 hours in a period of 24 hours so as to induce abortion in up to 9-week pregnancy. a group of pregnant volunteers with gestation times ranging from 35 to 63 days participated in the study. all the patients who had abortion received an additional dose of 600mg of misoprostol. a patient decided not to continue in the study after the first interview but her data were included in the general characteristics of the sample. the method was considered to be efficient when it caused complete abortion without requiring further surgical or causing secondary effects. fifty seven patients (64%) had complete abortion. the time of expulsion was 7,4 ± 3,8 h (median 7,2h, range 3-20h) for all the patients who had abortion in the first 24 hours of misoprostol administration. thirsty two cases failed, 28 were due to problems with the method after administering the third doses and 4 cases were due to medical decision. the obtained results in this study allowed us to conclude that the dose of 600mg of misoprostol is not the adequate dose to produce high or acceptable abortive efficacy
