In this paper, partial results of the diagnosis of the process management of teaching, research, and extension at the Language Centre, University of Pinar del Río, are presented. They show that these processes are not interrelated, which badly affects student training. Some suggestions for a better process management at the Centre are made with of the aim of improving these processes. Such improvement would be in tune with the goals of Cuban higher education.

The scientific research applied to the agrarian sciences in the last 50-60 years has generated a highly productive and profitable agriculture, but with great environmental and social consequences. The predominance of a short-term and reductionist approach, which does not take into account social and environmental costs, has resulted in this unsustainable model. A new paradigm in agrarian sciences is required that contemplates and minimizes long-term environmental and social impacts and generates more inclusive agriculture. This new paradigm has 3 interrelated components: a) sustainability, b) complexity and c) uncertainty. Agroecology emerges as that new paradigm and conception of research. From this new paradigm this article reflects on the topics to be investigated, the profile and training of the researchers and the characteristics of the Institutions and if they serve the methodologies designed and commonly used by research and extension.

A study of the natural regeneration of woody species under isolated bushes in a sector of northeast of Ibera Macrosystem is presented. The aim of the study was to evaluate the nurse effect of shrubs and structural parameters of regeneration. We show that the presence of isolated shrubs is fundamental to establish regeneration and that Ilex dumosa var. guaranina, Miconia chamissois, and Ocotea lancifolia promoted their abundance and richness. The regeneration involved 21 species, but was mainly structured by Miconia chamissois, Ilex dumosa var. guaranina, Citronella gongonha, and Myrsine parvula. The results indicate that Ilex dumosa var. guaranina was the most abundant solitary species and one of the best to regenerate under these conditions. While this shrub may constitute the initial stage in the formation of more or less large forests fragments, we suggest that the abundance of Ilex dumosa var. guaranina in this kind of primary woody succession prompted the expression "ka'a mirĩ" (the incipient forest), a guarani name of this species.

OBJECTIVE: identify the degree of diagnostic concordance between visual and digital analyses in detection of bone metastasis by bone gammagraphy in prostate cancer. INTRODUCTION: prostate cancer is the malignant neoplasm with highest incidence in men over 65 years of age. In Mexico approximately 14,200 new cases are diagnosed each year, which represent 11.7% of all new malignant tumors; of those, approximately 70% will develop metastasis in the course of the disease. Bone gammagraphy has been accepted as a means to identify bone metastases associated with several types of cancer, and therefore it is necessary to increase its sensitivity and specificity to ensure accurate diagnoses. One way to standardize diagnosis using the bone gammagram is using computerassisted techniques. This article shows the results obtained on making a comparison between the traditional visual method and a software enhanced visual method. MATERIAL AND METHODS: an observational and analytic study was conducted at Centro Médico Nacional La Raza, from January 1 through December 31, 2015, which included 138 patients with prostate cancer. Using bone gammagram we visually detected, by means of software and by tomography, the presence or absence of metastasis. A comparison between the three methods was made and the kappa index was used to quantify the degree of diagnostic concordance between them. RESULTS: the visual method identified 73.19% of patients without metastasis and 26.81% with metastasis. Likewise, using software we obtained 82.16% of cases without metastasis and 17.39% with positive result. Analysis by computed tomography identified 83.33% of patients without metastasis and 16.67% with metastasis. To calculate the kappa maindex, the number of findings obtained by visual observation with the aid of three specialists was considered standard. Findings using the software and by tomography were compared against that standard. The degree of diagnostic concordance between the visual and software-assisted methods was 73%. CONCLUSION: we consider acceptable the degree of diagnostic concordance between the visual and software-assisted methods, considering that this is the first time software is used to find bone metastasis. The results could improve when we are better familiarized with the use of the software. As an additional conclusion on the investigation, we find that bone metastasis is closely related to the value of the prostate-specific antigen given that the higher it is the greater the probability that bone metastasis is present; we observed that the incidence of metastasis was higher in patients with more than 10 ng/mL, which is consistent with the findings reported in the specialized literature.

In Córdoba city, several palm species have been used as ornamental elements in public green spaces and backyards. In this study, palms located in 25 sampling sites spread over the city were observed. Each palm was identified to species level, the occurrence of insects and damaged organs was assessed, and the percentage of herbivory was estimated. Only two phytophagous insect species significantly damaged palms in Córdoba city: Corialomela quadrimaculata (Coleóptera: Chrysomelidae) and Paysandisia archon (Lepidoptera: Castniidae). Geographic distribution of the C. quadrimaculata was expanded and new plant host récords were provided for both insect species. Damages caused by these insects are described and host preferences in relation to host availability in the city were analyzed. [ABSTRACT FROM AUTHOR]
