This research analyzes patterns of scientific production, citation and collaborative networks under three relationships (researcher/ researcher, researcher/center, and researcher/country), of the most productive researchers of four Latin American Marine Research Centers (MICs) over a 20-year period (2000-2020) from a bibliometric perspective. e Scopus search engine was used for the respective bibliometric analyses. In total, 57 most productive researchers were identified among the four centers; 5, 7, 14 and 31 for Centro i~mar, IOUSP, IICYM and CICESE, respectively. In two (i~mar and IICYM) of the four centers, researchers (AB) and (OI) recorded the highest number of publications, and were also the most cited; however, this pattern did not hold true for IOUSP and CICESE researchers. e collaboration network among the most productive researchers is segmented in certain defined groups, which causes a lack of internal cooperation among them, especially in Centro i~mar and IOUSP. In addition, it was evidenced that the most productive researchers concentrate their collaborations with other researchers belonging to Universities, Institutions or Centers of their own country, and very scarcely with international Centers, being their international cooperation conservative which in turn demonstrates scientific autonomy, and does not require external partners to make their research visible. This research contributes with the knowledge of the most productive centers and is the basis for future studies that suggests orienting and extending the analysis of the productivity of researchers with fewer publications and citations, as well as the analysis of their internal collaboration network.

The Lafken Mapu Lahual Coastal Marine Protected Area of Multiple Uses (Lafken Mapu Lahual), Osorno coast, southern Chile, is one of the first protected areas of created in Chile during 2006, but only in 2019 its Management Plan was presented. This study provides information on its marine mammal species to be used in future biodiversity monitoring plans. The sighted mammals were recorded and counted through 18 navigation tracks and one observation point in the 2014-2015 austral breeding season. Five species were recorded systematically (one whale species, two dolphin species, one marine otter species and a one sea lion species). Two of them (Lontra felina and Balaenoptera musculus) are classified by the IUCN in the conservation category corresponding to Endangered. Laken Mapu Lahual is an important area for the species of whales that use it for their migratory route to the south of Chile. [ABSTRACT FROM AUTHOR]

Introduction: Dermoid cysts are uncommon lesions from ectodermic origin. Only 1.6% arise in the floor of the mouth, and at this site only 6% arise laterally in the submandibular region. Aim: Case report and review of the literature. Clinical Case: 32 years old patient, with a slow growing lesion during 1 year. Complete resection with an ipisilateral submandibulectomy was performed. The pathologic report showed a dermoid cyst. Discussion: The localization of this lesion is very uncommon. In the pathologic report are lesion with pluri stratified cornified epthitelium with skin attachments. Image studies show a cystic lesion being the magnetic resonance the best study to characterize this lesions. Are benign lesions, without recurrence reported when the lesion has been fully excised.

There is a concern that the pressure to increase the number of papers in high impact factor journals could be detrimental to the quality of research, and therefore, to the impact that it might have in the international scientific community. In this work, we have done a scientometric and statistical analysis of published articles by Argentine, Brazilian, Chilean, and Mexican ecologists from 1975 to 2015, to test this hypothesis. H-index values (which measures an article's number of citations and total items published) were recorded in the top 10 journals for each country. While the number of publications grew exponentially in these four countries since 2000, we observed that the number of citations decreased markedly, which is to say that promoting scientific productivity by stimulating an increase in the number of publications in high impact factor journals, the dominant scientific policy in many Latin American countries, does not necessarily reflect greater insertion into the international scientific debate, but rather the current scientific policies have produced the opposite outcome. Publishing fewer papers, but with greater quality and depth, or perhaps dedicating ourselves to strengthening scientific and technological systems that are linked with local and regional needs (and evaluated accordingly), could be an alternative, but wiser, path to build a regional ecology with greater global impact, relevance, pertinence and visibility.

The Magellanic Flightless Steamer Duck (Tachyeres pteneres) is the only marine anatid founded along the coastline of Chile and Argentina, from Valdivia to Tierra del Fuego. There is little published information about the quantitative diet of this species. Previously, a single study of its breeding diet was reported for Guapiquilán Island, Chiloé, southern Chile. We studied T. pteneres' winter diet during 2011 and 2012 in Bahía Caulín, Chiloé, southern Chile. We found that statistically Cancridae crabs (100 and 100%, respectively) and Majidae (96.0-71.4%, respectively) were the most common items in the diet of this species. [ABSTRACT FROM AUTHOR]

The Hirsch's h-index is a new bibliometric indicator that has been considered useful to evaluate the scientific productivity of individual researchers and scientific journals. This paper uses it to evaluate the productivity of the 15 research universities of Chile. Since in Chile public rankings of perception of their universities are beginning to be common, the article relates the h-index with a pair of rankings based on the prestige that the potential employers and students of the last level of secondary education have of them. I found that both rankings of perception were related and the same happened when they were associated to the h-index of Hirsch. The association was greater for the ranking based on the perception by potential students at those universities. [ABSTRACT FROM AUTHOR]

Based on a review of previous studies on rural wage labour, this survey attempts to evaluate the relevance, contribution of, and possibilities for developing a sociology of labour markets within this area of interest.We begin by defining the main characteristics of the so called sociological theory of labour markets, recreating its developmental process within the science of economics. Then,we analyse how various ruralwage labour studies have paid attention to empirical phenomena or employed theoretical ideas related specifically to the area of labour markets and, especially, to the themes posed by the sociological approach to them. We conclude that the sociology of labor markets has been present one way or another since the establishment of rural wage laborers analysis as a field of study. Among the analytical aspects involved in the conception of labor markets as social institutions,we assert that the area least tackled in specific research has so far been the historical or genetic one.Finally, we sustain that one of the principal ways available to continue developing the potential of the sociological approach is, precisely, to include it and go deeper into those aspects of analysis in studies of rural labor markets.
