Known only from West Bengal, India. Remarks. The male resembles that of Stictochironomus obscurus in the largely pale-yellow wing with three dark markings on the cell r 4+5 and the slender, gently curved superior volsella in the hypopygium, but differs from it in the wing with markings on the apices of cells m 1+2 and m 3+4, the apically bifid anal point and the anal tergite without median setae. In S. obscurus, the wing cells m 1+2 and m 3+4 have no apical marking, the anal point is simple and the anal tergite has several median setae, according to Guha & Chaudhuri (1983: 637, figures 1, 3, as Polypedilum) and Chaudhuri & Chattopadhyay (1990: 187, figs. 41, 43). The bifid anal point is unique in the genus Stictochironomus. Sometimes a bifid anal point also occurs in the male of Japanese Sympotthastia takatensis (Tokunaga), belonging to the subfamily Diamesinae, and it is not rare (H. Niitsuma, pers. comm.). Although the two localities where the larvae of the present species were collected are far away from each other and the features are common to all the males emerged from the larvae, there is a possibility that the bifid anal point is an intraspecific variation. Further, the anal tergite without median setae is an atypical feature in the male of this genus. In the diagnosis for the male, Cranston et al. (1989: 416) wrote, “median anal tergite setae long, concentrated in field between ends of bands, separate from apical setae; exceptionally in S. crassiforceps without median anal tergite setae.” The present species differs from S. crassiforceps (Kieffer) in the slender superior volsella and the longer gonostylus in the male hypopygium. The male of the latter possesses stout superior volsellae and short gonostyli (see Cranston et al. 1989: 491, figure 10.65C). Therefore, the present species is distinct from the other members of this genus. Within the S. caffrarius group, the pupa is similar to those of S. polystictus and S. caffrarius in the abdominal segments II‒III each with three pairs of L-setae, but separable from the pupa of S. polystictus by the slender cephalic tubercle, which is higher than the basal width, and from the pupa of S. caffrarius by the anal tergite without any shagreen. Stictochironomus polystictus has cephalic tubercles as high as the basal width (Blattacharyay et al. 1996: 323), and S. caffrarius possesses anterolateral shagreen on the anal tergite (Pinder & Cranston 1986: 456, fig. 10.91D, as Chironomini Genus F sp.). The larva is most similar to that of S. polystictus described by Blattachayay et al. (1996) in the relatively high AR (1.20‒1.29), the mentum with three median teeth and the mandible with a dorsal tooth and three inner teeth, although Hazra et al. (2016) reported the larva of S. polystictus with lower AR (0.74‒0.92) and four inner teeth on the mandible under the name of Polypedilum clavipennae, which was synonymized with S. polystictus by Mukherjee et al. (2020). In any case, the larva of the present species is separated from both the larval types of S. polystictus by the smaller head capsule (length 250‒280 µm). The larval head capsule of S. polystictus is 285‒315 µm long in Blattachayay et al. (1996) and 380‒420 µm long in Hazra et al. (2016).Published as part of Konar, Sanghamitra, 2021, A new member of the Stictochironomus caffrarius group from West Bengal, India with emendation of generic diagnosis (Diptera, Chironomidae), pp. 173-181 in Zootaxa 5072 (2) on pages 174-176, DOI: 10.11646/zootaxa.5072.2.6, http://zenodo.org/record/573374

Cierre percutáneo de comunicación interventricular con el dispositivo KONAR-MF
RESUMEN Introducción y objetivos: El cierre percutáneo de la comunicación interventricular (CIV) puede ser una alternativa a la cirugía y reduce el tiempo de hospitalización y las complicaciones. El alto riesgo de bloqueo auriculoventricular (BAV) en el cierre percutáneo ha incentivado el desarrollo de nuevos dispositivos, como el KONAR-MF (Lifetech, China), muy flexible y con poca fuerza radial para adaptarse a la anatomía de la CIV sin presionar las estructuras adyacentes. Se presenta la experiencia inicial con este nuevo dispositivo. Métodos: Revisión retrospectiva de pacientes y procedimientos de implante del dispositivo KONAR-MF, en 2 centros españoles, desde febrero de 2020, fecha del primer implante en nuestro país, hasta septiembre de 2021. Resultados: Se han realizado 7 procedimientos de cierre de CIV con KONAR-MF, implantándolo con éxito en 6 de los casos. Fueron 4 CIV perimembranosas nativas y 3 CIV residuales tras reparación de tetralogía de Fallot. El tamaño de la CIV medido por ecocardiografía transesofágica y angiografía fue concordante en todos los casos salvo en uno; en este paciente se produjo una embolización del dispositivo. En el seguimiento (1,2 meses [rango intercuartílico: 0,9-15,5], máximo 17 meses) se observó un empeoramiento de la conducción auriculoventricular en un paciente con BAV previo, que precisó marcapasos. La tasa de shunt residual inmediato fue del 83% (5/6), persistiendo el shunt residual más allá del mes de seguimiento en 1 paciente (16%). Todos los pacientes recibieron el alta hospitalaria en las primeras 48 horas tras la intervención. Conclusiones: El cierre percutáneo de CIV con el dispositivo KONAR-MF es una alternativa factible a la cirugía en pacientes seleccionados, siendo la adecuada valoración anatómica de la CIV una de las claves para el éxito del procedimiento. El implante de este dispositivo no está exento de complicaciones, como el BAV y la embolización. Palabras clave: Comunicación interventricular. Intervencionismo en cardiopatías congénitas.

Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Evolution of the global virtual water trade network
Global freshwater resources are under increasing pressure from economic development, population growth, and climate change. The international trade of water-intensive products (e.g., agricultural commodities) or virtual water trade has been suggested as a way to save water globally. We focus on the virtual water trade network associated with international food trade built with annual trade data and annual modeled virtual water content. The evolution of this network from 1986 to 2007 is analyzed and linked to trade policies, socioeconomic circumstances, and agricultural efficiency. We find that the number of trade connections and the volume of water associated with global food trade more than doubled in 22 years. Despite this growth, constant organizational features were observed in the network. However, both regional and national virtual water trade patterns significantly changed. Indeed, Asia increased its virtual water imports by more than 170%, switching from North America to South America as its main partner, whereas North America oriented to a growing intraregional trade. A dramatic rise in China's virtual water imports is associated with its increased soy imports after a domestic policy shift in 2000. Significantly, this shift has led the global soy market to save water on a global scale, but it also relies on expanding soy production in Brazil, which contributes to deforestation in the Amazon. We find that the international food trade has led to enhanced savings in global water resources over time, indicating its growing efficiency in terms of global water use.ECH
