Bibliometrics play a significant role in evaluating the scientific production of journals and research units such as universities and research centers. The present study aimed to analyze the scientific production of CIMAR (Center for Research in Marine Science and Limnology) from its foundation in 1979 to 2015. We analyzed exclusively articles published in journals and selected those with at least one author affiliated to CIMAR. For the analysis, each article was classified according to the geographical study area, the topic of the investigation, ecosystem, and taxonomic group. We analyzed the following variables: year of publication, language, journal name, and authors. In this study, we analyzed the Bradford distribution, citations, the impact factor, and the quartiles of the journals where papers were published. During the study period, CIMAR produced a total of 791 publications: 624 articles, 90 book chapters or books, 48 booklets, and 34 special issues of the journal Revista de Biología Tropical (RBT). The number of publications showed an increasing trend during the study period, and most articles were written in English (58.3 %) and Spanish (41.7 %). A total of 128 journals were selected to publish CIMAR’s contributions. According to the Bradford method, the journal RBT is in Zone I (major productivity or concentration), with 49.8 % of the total scientific production. In relation to authorship, 22 authors with 12 articles or more are registered, and 80 % of the articles have been published by authors with a low (42 authors) and medium productivity level (44 authors). CIMAR published 81.6 % regarding marine topics and 18.4 % about limnology. Most of the articles (51.9 %) dealt with the Pacific of Costa Rica, 13.5 % with the Caribbean and 34.7 % referred to other study locations. The publications of CIMAR were mainly about ecology (33.3 %), taxonomy (24.5 %) and oceanography/meteorology (12.7 %). CIMAR has a highly trained and specialized staff that has gained experience and is contributing to the implementation and evaluation of Costa Rica’s science, technology and innovation policies through both interdisciplinary research and the development of institutional as well as professional capacities in a framework of dialogue and public-private agreements.

Abstract: The objectives of this report are to make accessible data on the abundances (1984-1987, 49dates) of sipunculans, brachiopods and hemichordates at a sand-mud flat, and on trace metals (1996,2000) and abundances (2015, 3 dates) of sipunculans and brachiopods at a sand flat in the upper Gulf ofNicoya estuary (10oN-85oW), Pacific coast of Costa Rica. Core (17.7 cm2) samples were collected at thesand-mud flat, and quadrats (0.2 m2) at the sand flat. Trace metal (Fe, Mn, Ni, Cr, Cd, Zn, and Pb)analyses were performed by Atomic Absorption Spectrometry (AAS) in tissues of the infaunal depositfeeder sipunculan Sipunculus nudus (non-depurated vs depurated) and in tissues and shells of theinfaunal filter-feeder brachiopod, Glottidia audebarti. The flats contrast in their sand (65% vs 90%) andsilt+clay (31.5% vs 5.6%) contents. At the sand-mud flat the brachiopods were represented by 129individuals, the sipunculans by 13, and the hemichordates by 185. The total area sampled by cores was1.83 m2. Estimated densities for the dates when the maximum number of each group was found, were: 29,5.7, and 40 ind./m2, respectively. Abundances were higher during the rainy season of 1984. Trace metalconcentrations in S. nudus collected at the sand flat decreased for all metals (except Cd) when medianvalues of non-depurated vs depurated individuals were compared. Maximum concentrations in non-depurated specimens, were: Fe (22.5 mg/g. dw) > Mn (234.6 µg/g. dw) > Zn (144.0 µg/g. dw) > Cu(52.7µg/g. dw) > Ni (15.5 µg/g. dw) > Cr (10.8 µg/g. dw) > Pb (9.3 µg/g. dw) > Cd (1.64 µg/g. dw).Maximum concentrations in non-depurated G. audebarti, were: Fe (21.6 mg/g. dw-soft parts) > Mn (Nodata) > Zn (123.4 µg/g. dw- soft parts) > Cu (31.4 µg/g. dw-pedicles) > Ni (No data) > Pb (21.0 µg/g.dw-shells) > Cd (5.2 µg/g. dw-soft parts) > Cr (4.7 µg/g. dw-shells). Maximum concentrations insediments were: Fe (60.3 mg/g. dw) > Mn (549.3 µg/g. dw) > Zn (83.1 µg/g. dw) > Cu (36.2 µg/g. dw)> Cr (31.5 µg/g. dw) > Pb (21.1 µg/g. dw) > Ni (20.6 µg/g. dw) > Cd (1.1 µg/g. dw).Theseconcentrations were expected for a non-industrialized estuary like the Gulf of Nicoya. At the sand flat, atotal of 76 individuals of G. audebarti, 112 of G. albida, and 366 of S. nudus were collected in 2015, in atotal sampled area of 10.6 m2. Estimated mean densities for the three dates were: 7.1, 10.5, and 31 ind./m2, for G. audebarti, G. albida, and S. nudus, respectively. The spatial distribution of the three specieswas aggregated and the maximum numbers found in a quadrat (0.2 m2) were 11, 18 and 20, respectively.The size range of G. audebarti was from 9.0 mm to 38.0 mm, and from from 6.0 mm to 29.0 mm for G.albida. The weight range of S. nudus was from 0.10 g to 2.55 g. These ranges are within those found forthese species elsewhere. Densities of G. audebarti and G. albida were relatively low, while those of S.nudus were relatively high when compared with data reported in the literature. No acorn worms werefound in 2015. G. audebarti had a relatively stable abundance, while G. albida decresed at the end of therainy season of 2015. The abundance of S. nudus increased towards the end of the rainy season andheavier (more than 1.25 g) specimens were also collected at this time. A strong ENSO was fullydeveloped in 2015 leading to above normal average temperatures and less rainfall in the Pacific coast ofCosta Rica, but the impact of this warming event on the fauna is unknown.

Positive Effect

This paper presents a bibliometric analysis of the scientific activity of Spain in Marine Science through the analysis of its publications in the Science Citation Index during the period 1994-2004. The evolution of collaboration over the period and the influence of different types of collaboration on the impact of research are studied. Spanish production accounts for 6,898 publications. An increment in the number of publications and in the impact of the publication journals over time is observed. Internationally-coauthored publications increase faster than those with national or with no collaboration at all and tend to be published in more prestigious journals and to receive a higher number of citations. The indicators “gain in impact factor” and “gain in citations” are used to measure the effects of different types of collaboration over the impact of the research for the main institutional sectors in the country, main research centres and most productive scientists. A positive effect of collaboration over the impact of research is observed, but as the aggregation level of analysis decreases this positive effect is less clear. In the case of individual scientists this good relationship between international collaboration and impact of publications is not always observed.

Objectives: to analyze the scientific production of nurses on hospital infection, to evaluate the impact of the ordinance MS-196/83 to quantify the production in different decades and list the main measures of prevention and control. Methodology: literature review study was carried out manually from 1980 to 2006, in Brazilian nursing journals of the acquis of the Central Library of the University of São Paulo. Results: 33 publications totaled up nursing on hospital infection, from 2000 to 2006 concentrates the largest number of jobs in this area. Showing participation of 65% of teachers in scientific production. We noticed the high number of publications in order to study law, ethics and CCIH 13 (40%) which emphasize the role of nurses in the context of nosocomial infection and the importance of the role of the Committee for Hospital Infection Control, and the high percentage of studies descriptive / exploratory, seeking to change behavior and control of hospital infection. Conclusion: the fight against hospital infections presents itself today as a complex problem. We recognize that although the theme hospital infection is very common and widely disseminated in the national nursing is still poorly addressed. Descriptors: nosocomial infection; nursing; cientific production.

The Impact

Global tree cover products face challenges in accurately predicting tree cover across biophysical gradients, such as precipitation or agricultural cover. To generate a natural forest cover map for Costa Rica, biases in tree cover estimation in the most widely used tree cover product (the Global Forest Change product (GFC) were quantified and corrected, and the impact of map biases on estimates of forest cover and fragmentation was examined. First, a forest reference dataset was developed to examine how the difference between reference and GFC-predicted tree cover estimates varied along gradients of precipitation and elevation, and nonlinear statistical models were fit to predict the bias. Next, an agricultural land cover map was generated by classifying Landsat and ALOS PalSAR imagery (overall accuracy of 97%) to allow removing six common agricultural crops from estimates of tree cover. Finally, the GFC product was corrected through an integrated process using the nonlinear predictions of precipitation and elevation biases and the agricultural crop map as inputs. The accuracy of tree cover prediction increased by ≈29% over the original global forest change product (the R2 rose from 0.416 to 0.538). Using an optimized 89% tree cover threshold to create a forest/nonforest map, we found that fragmentation declined and core forest area and connectivity increased in the corrected forest cover map, especially in dry tropical forests, protected areas, and designated habitat corridors. By contrast, the core forest area decreased locally where agricultural fields were removed from estimates of natural tree cover. This research demonstrates a simple, transferable methodology to correct for observed biases in the Global Forest Change product. The use of uncorrected tree cover products may markedly over- or underestimate forest cover and fragmentation, especially in tropical regions with low precipitation, significant topography, and/or perennial agricultural production.

The Impact

This reflexive essay examines the adoption of an intentional ‘ethic of care’ by social work administrators in a large social work school located in the Pacific Northwest. An ethic of care foregrounds networks of human interdependence that collapse the public/private divide. Moreover, rooted in the political theory of recognition, a care ethic responds to crisis by attending to individuals’ uniqueness and ‘whole particularity.’ Foremost, it rejects indifference. Through the personal recollections of one academic administrator, the impact of rejecting indifference in spring term 2020 is described. The essay concludes by linking the rejection of indifference to the national political landscape.

AbstractThe severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) pandemic has proven a challenge to healthcare systems since its first appearance in late 2019. The global spread and devastating effects of coronavirus disease 2019 (COVID-19) on patients have resulted in countless studies on risk factors and disease progression. Overweight and obesity emerged as one of the major risk factors for developing severe COVID-19. Here we review the biology of coronavirus infections in relation to obesity. In particular, we review literature about the impact of adiposity-related systemic inflammation on the COVID-19 disease severity, involving cytokine, chemokine, leptin, and growth hormone signaling, and we discuss the involvement of hyperactivation of the renin-angiotensin-aldosterone system (RAAS). Due to the sheer number of publications on COVID-19, we cannot be completed, and therefore, we apologize for all the publications that we do not cite.

The Impact

Cable tensile forces in winch-assist harvesting have been investigated in order to assess the safety concerns of the technology. However, the literature is lacking, particularly in regards to the impact of winch design. In this study, a Summit Winch Assist tethering a feller-director on ground slopes up to 77% was monitored for four days. The cable tensile forces were simultaneously recorded at the harvesting and anchor machine at a frequency of 100 Hz. Cameras and GNSS devices enabled a time study of the operations and the recording of machine positions. Winch functionality and design were disclosed by the manufacturer and used for the interpretation of the results. The cable tensile forces reached 296 kN at the harvesting machine and 260 kN at the anchor machine. The slow negotiation of obstacles while moving downhill recorded the highest peaks, mainly due to threshold settings of the winch in the brake system activation. Lower but significant peaks were also recorded during stationary work tasks. The peaks, however, were limited to a few events and never exceeded the endurance limit of the cable. Overall, the study confirmed recent findings in cable tensile force analysis of active winch-assist operations and provided evidence of the underlaying mechanisms that contribute to cable tensile forces.

The Impact

Abstract Development aid, one of the most important mechanisms for the redistribution of global wealth, represents financial flows that have economic growth and social improvement as their main objective. It has also frequently been described as an instrument which is able to diminish international migrations and is used by several developed countries. Recently, much empirical evidence and several contributors have argued that connection and set out other grounds. This paper explores the interaction between development aid and migrations from developing to developed countries. We want to determine, if the amount of development aid has any impact on migrations from African, Caribbean, and the Pacific Group of States. Our results show that development aid does not have a direct effect on migrations and therefore, in terms of international migrations, is not effective. Moreover, we will argue that the donor side should use different policies and other mechanisms to manage migrations from those countries
