Problematic Internet uses and depression in adolescents: A meta-analysis
Authors: Lozano-Blasco Raquel , Cortés-Pascual Alejandra 
Published: January 2020

Widespread use of the Internet in 21st century society is not risk-free. This paper studies the comorbidity of some problematic uses of Internet with depression in order to assess their correlation. With that aim, a meta-analysis of 19 samples obtained from 13 different studies (n=33,458) was carried out. The subjects of these studies are adolescents between the ages of 12 and 18 years (µ=15.68) from different cultures and continents (Europe, Euro-Asia, America and Asia). The effect size obtained from the use of a random-effects model (r=0.3, p<0.000) is significant, moderate and positive, thus confirming the relation between pathologic uses of the Internet and depression. Moreover, meta-regression test results showed that 9% of the variance (R2=0.09) is associated with the male gender, while age and culture are not significant variables. The variability rate of the studies is high (I2=87.085%), as a consequence of heterogeneity rather than publication bias, as Egger’s regression test shows (1-tailed p-value=0.25; 2-tailed p-value=0.50, and ?=1.57). Therefore, the need for specific interventions in secondary education dealing with this issue is evident to ensure that it does not extend into adult life.
El uso extendido de Internet en la sociedad del siglo XXI no está exento de riesgos. El presente trabajo estudia la comorbilidad entre los usos problemáticos de Internet y la depresión con la finalidad de determinar la existencia de relación entre ambas. Para ello se ha llevado a cabo un meta-análisis, que cuenta con 19 muestras recogidas en 13 investigaciones (n=33.748), con adolescentes de entre 12 y 18 años (µ=15,68) de diferentes culturas y continentes (Europa, Euro-Asia, América y Asia). El tamaño del efecto obtenido a partir de un modelo de efectos aleatorios (r=0,3, p<0,000) es significativo, positivo y moderado confirmando la existencia de relación entre usos patológicos de Internet y depresión. Por otra parte, la meta-regresión mostró que el 9% (R2=0,09) de la varianza es explicada por el sexo masculino, mientras que la edad y la cultura no son variables significativas. La variabilidad de los estudios es elevada (I2=87,085%) siendo fruto de la heterogeneidad y no del sesgo de publicación, tal y como indicó la prueba de regresión de Egger (p-value 1 tailed=0,25; p-value 2 tailed=0,50 y ?=1,57). Se advierte la necesidad de comenzar a generar proyectos de intervención en Educación Secundaria que traten esta problemática con el objetivo de que no se extienda a la vida adulta.

Modeling the effects of sediment concentration on the propagation of flash floods in an Andean watershed
Authors: Contreras María Teresa , Escauriaza Cristián 
Published: January 2020

Abstract. Rain-induced flash floods are common events in regions near mountain ranges. In peri-urban areas near the Andes the combined effects of the changing climate and El Niño–Southern Oscillation (ENSO) have resulted in an alarming proximity of populated areas to flood-prone streams, increasing the risk for cities and infrastructure. Simulations of rapid floods in these watersheds are particularly challenging, due to the complex morphology, the insufficient hydrometeorological data, and the uncertainty posed by the variability of sediment concentration. High concentrations produced by hillslope erosion and rilling by the overland flow in areas with steep slopes and low vegetational covering can significantly change the dynamics of the flow as the flood propagates in the channel.
In this investigation, we develop a two-dimensional finite-volume numerical model of the nonlinear shallow water equations coupled with the mass conservation of sediment to study the effects of different densities, which include a modified version of the quadratic stress model to quantify the changes in the flow rheology.
We carry out simulations to evaluate the effects of the sediment concentration on the floods in the Quebrada de Ramón watershed, a peri-urban Andean basin in central Chile. We simulate a confluence and a total length of the channel of 10.4 km, with the same water hydrographs and different combinations of sediment concentrations in the tributaries.
Our results show that the sediment concentration has strong impacts on flow velocities and water depths. Compared to clear-water flow, the wave-front velocity slows down more than 70 % for floods with a volumetric concentration of 60 % and the total flooded area is 36 % larger when the sediment concentration is equal to 20 %. The maximum flow momentum at cross sections in the urban area increases 14.5 % on average when the mean concentration along the main channel changes from 30 % to 44 %. Simulations also show that other variables such as the arrival time of the peak flow and the shape of the hydrograph at different locations along the channel are not significantly affected by the sediment concentration and depend mostly on the steep channel morphology.
Through this work we provide a framework for future studies aimed at improving hazard assessment, urban planning, and early warning systems in urban areas near mountain streams with limited data and affected by rapid flood events.

Published: January 2020

Abstract. Hydro-meteorological risks due to natural hazards such as severe floods, storm surges, landslides and droughts are causing impacts on different sectors of society. Such risks are expected to become worse given projected changes in climate, degradation of ecosystems, population growth and urbanisation. In this respect, nature-based solutions (NBSs) have emerged
as effective means to respond to such challenges. A NBS is a term used for
innovative solutions that are based on natural processes and ecosystems to
solve different types of societal and environmental challenges. The present
paper provides a critical review of the literature concerning NBSs for
hydro-meteorological risk reduction and identifies current knowledge gaps
and future research prospects. There has been a considerable growth of
scientific publications on this topic, with a more significant rise taking
place from 2007 onwards. Hence, the review process presented in this paper
starts by sourcing 1608 articles from Scopus and 1431 articles from the Web of
Science. The full analysis was performed on 146 articles. The analysis
confirmed that numerous advancements in the area of NBSs have been achieved
to date. These solutions have already proven to be valuable in providing
sustainable, cost-effective, multi-purpose and flexible means for
hydro-meteorological risk reduction. However, there are still many areas
where further research and demonstration are needed in order to promote
their upscaling and replication and to make them become mainstream
solutions.
Translating the Near East in the Man of Law's Tale and Its Analogues
Authors: Stavsky Jonathan 
Published: January 2020

Abstract
Using Chaucer's Man of Law's Tale and other Middle English narratives of falsely accused heroines as its test case, this article develops a comparative methodology for analyzing representations of the Near East that focuses on their adaptation of earlier (Anglo-)French sources and juxtaposing them with these sources' late medieval remaniements. It argues that Gower's “Tale of Constance,” the Northern and Southern Octavian, and, especially, Le Bone Florence of Rome, as well as the bookmakers who preserved the romances in question, exhibit various strategies for defusing the crusader ideology of their francophone counterparts. Chaucer, in turn, both appropriates these maneuvers and escalates the conflict between Christianity and Islam that underlies the Constance story in Trevet's Les Cronicles, only to contrast it with an inner struggle against idolatry advocated in the Parson's Tale.
“Kek kek! kokkow! quek quek!”: The Glorious Cacophony of Chaucer's Parliament of Fowls
Authors: Hanssen Ken R. 
Published: January 2020

Abstract
From his initial reading of Macrobius to the bird choir's parting roundel, the narrator of Chaucer's Parliament of Fowls must consider competing versions of love, nature, and human agency, but at the end he remains as uncertain and unresolved as he was at the beginning. Rather than settling the questions with which the poem is concerned, Chaucer, through the waking and dreaming experience of his poetic persona, enacts a psychodynamic interchange in which the ongoing negotiations between experience and authority, flesh and spirit, nature and the divine, are fluid, bidirectional, and mutually dependent. This suggests not only that the condition of embodiment forms the nexus of the poem's various conceptualizations of love, but also the more incisive point that the formulation of any higher good depends on our ability to have clashing ideas “knyt by evene noumbres of acord.”
Witchcraft and Sorcery in Piers Plowman
Authors: Gasse Rosanne 
Published: January 2020

Abstract
This article explores the theme and language play around witchcraft and sorcery in Piers Plowman. Langland's place in the late medieval English discourse on magic deserves to be recognized beyond Dame Studie's denunciation of sorcery at B.10.209–17. Though belief in magic was widespread throughout the medieval period, Langland is a skeptic who rejects any possibility of humans wielding real magic, even in collusion with demons. Witches and sorcerers like Mahomet, Sire Penetrans, and Favel are simple frauds and charlatans who rely upon props and manipulative skill over gullible marks. Langland also recognizes a type of sorcery that exists without magical power but is a label for esoteric and advanced intellectual study. Most intriguing, however, is Langland's manipulation of the false accusation of witchcraft against one's opponent. Jesus, the only genuine sorcerer in the text, is named as a witch as actual proof of his divine nature and omnipotence.
Dos best-sellers da cultura de massa ao cânone literário: sequência didática como possibilidade
Authors: Lima Luzimar Silva de Lima Silva , Alves Shirlei Marly 
Published: January 2020

Os aspectos referentes a leitura, mais especificamente à leitura literária na escola, têm se apresentado como um terreno frutífero de novas preferências. Sobre isso, percebe-se uma primazia dos estudos da literatura canônica sob outras possibilidades de leitura no ambiente escolar. Os best-sellers da cultura de massa ocupam um espaço cada vez maior nas atividades de leitura dos jovens leitores dentro e fora da escola. Em contrapartida, há uma forte imposição da literatura canônica e frustração das expectativas do leitor. Objetivamos a realização de um trabalho de aproximação entre cânone literário e best-sellers da cultura de massa, elegemos as obras Como eu era antes de você de Jojo Moyes e Lucíola de José de Alencar, com as quais construímos duas sequências didáticas. Para tanto, busca-se responder a seguinte questão: como a leitura de best-sellers pode favorecer a inserção das obras canônicas na escola e para a formação crítica do leitor? Nesse trabalho, realizou-se uma pesquisa de cunho bibliográfico pelo método hipotético dedutivo tendo como suporte teórico: Barthes (1987), Jauss (1984), Moisés (2006), Lajolo e Zilberman (2009), Cosson (2015). Assim, foi possível oferecer uma forma de trabalho com a literatura valorizando experiências de leituras.
Pancreatic Solid Pseudopapillary Neoplasm: Key Pathologic and Genetic Features
Authors: La Rosa Stefano , Bongiovanni Massimo 
Published: January 2020

Context.—
Solid pseudopapillary neoplasm of the pancreas is a low-grade malignant tumor generally associated with a good prognosis. Solid pseudopapillary neoplasms show peculiar morphologic features, but sometimes the differential diagnosis with other pancreatic neoplasms (ie, pancreatic neuroendocrine tumors) can be a challenging task, especially in cytologic or biopsy specimens. In these cases immunohistochemistry is a useful tool, but the diagnostic utility of several proposed immunohistochemical markers is questionable. In recent years, despite several attempts to characterize the pathogenetic, molecular, and prognostic features of solid pseudopapillary neoplasms, they still remain unclear.

Objective.—
To give the reader a comprehensive update on this entity.

Data Sources.—
The PubMed database (US National Library of Medicine) was searched using the following string: pseudopapillary tumor [AND/OR] neoplasm [AND/OR] pancreas. All articles written in English were included. In addition, because a heterogeneous terminology has been used in the past to define solid pseudopapillary neoplasms, the reference lists of each paper selected in the PubMed database were also reviewed.

Conclusions.—
This review gives a comprehensive update on the pathologic, clinical, and molecular features of solid pseudopapillary neoplasms, particularly addressing issues and challenges related to diagnosis. In addition, we have tried to correlate the molecular alterations with the morphologic and clinical features.
Conducting a Pathology Research Study, From Start to Finish
Authors: Gonzalez Raul S. , Mukhopadhyay Sanjay , Fine Samson W. , Jiang Xiaoyin (Sara) 
Published: January 2020

Context.—
Many pathologists-in-training enter residency or fellowship with either no formal experience in research or with a basic science research background that may not translate well to research in the realm of diagnostic pathology, including surgical pathology, cytopathology, and clinical pathology.

Objective.—
To provide a starting point and practical framework for residents or fellows who wish to conduct research in these fields.

Data Sources.—
Existing literature and the pooled experience of the authors, all academic pathologists.

Conclusions.—
We provide tips and tricks that trainees will find useful when planning and executing pathology research projects. A key component of successful research in diagnostic pathology is active guidance by a skilled faculty mentor, bolstered by enthusiastic, timely work by a highly motivated and dedicated trainee. We hope this advice will improve interactions between trainees and their faculty mentors and enhance the quality of research in diagnostic pathology.

Background As the demand for cosmetic surgery continues to rise, plastic surgery programs and the training core curriculum have evolved to reflect these changes. This study aims to evaluate the perceived quality of current cosmetic surgery training in terms of case exposure and educational methods.
Methods A 16-question survey was sent to graduates who completed their training at a U.S. plastic surgery training program in 2017. The survey assessed graduates’ exposure to cosmetic surgery, teaching modalities employed and their overall perceived competence. Case complexity was characterized by the minimum number of cases needed by the graduate to feel confident in performing the procedure.
Results There was a 25% response rate. The majority of respondents were residents (83%, n=92) and the remaining were fellows (17%, n=18). Almost three quarters of respondents were satisfied with their cosmetic training. Respondents rated virtual training as the most effective learning modality and observing attendings’ patients/cases as least effective. Perceived competence was more closely aligned with core curriculum status than case complexity, i.e. graduates feel more prepared for core cosmetic procedures despite being more technically difficult than non-core procedures.
Conclusions Despite the variability in cosmetic exposure during training, most plastic surgery graduates are satisfied with their aesthetic training. Incorporation of teaching modalities, such as virtual training, can increase case exposure and allow trainees more autonomy. The recommended core curriculum is adequately training plastic surgery graduates for common procedures and more specialized procedures should be consigned to aesthetic fellowship training.

Background Methods for identifying local lymph node metastasis in malignant melanoma include sentinel lymph node biopsy (SLNB) and lymph node dissection (LND). In particular, SLNB has been widely used in recent years. This study aimed to retrospectively confirm the adequacy of the current indication criteria for SLNB by applying those criteria to a mixed group of patients who previously received SLNB and LND.
Methods This study included 77 patients with malignant melanoma of the extremities and trunk who were monitored for >24 months. The patients were classified according to whether the current indication criteria for SLNB were applicable. The sentinel lymph nodes were evaluated for each group. Patients for whom the indication criteria for SLNB and LND were applicable were analyzed according to whether SLNB or LND was performed. Finally, the outpatient records of these patients were reviewed to evaluate recurrence, metastasis, and prognosis.
Results Of the 77 patients, SLNB was indicated according to the current criteria in 60 cases. Among the 60 patients for whom SLNB was indicated, 35 survived the follow-up period disease-free, 21 died during the follow-up period, and four experienced metastasis. The 17 patients for whom SLNB was not indicated had no recurrence or metastasis.
Conclusions Patients for whom SLNB was not indicated had no recurrence or metastasis. In cases where SLNB is indicated, the possibility of metastasis and recurrence may be high even if SLNB is negative or LND is performed, so more aggressive treatment and careful follow-up are crucial.
Desarrollo rural y actores locales. Los interrogantes de una Organización Institucional de Competencia Económica Dinámica en crisis: El caso SanCor en la provincia de Santa Fe, Argentina
Authors: Lattuada Mario , Renold Juan Mauricio 
Published: January 2020

El estudio de caso de SanCor Cooperativas Unidas Limitada es relevante por varios motivos. El primero, por la importancia económica y social que tiene en el sector lácteo nacional y en las localidades del interior donde radican sus plantas en las tres provincias más importantes de la Argentina: Santa Fe, Córdoba y Buenos Aires. En segundo lugar, constituye un ejemplo de un proceso organizacional evolutivo que atraviesa distintos estadios, nace como cooperativa de segundo grado y, luego de casi un siglo de existencia, se reconvierte en una cooperativa de primer grado, para terminar finalmente enajenando la casi totalidad de sus activos y gerenciamiento a otras empresas del sector. Tercero, su evolución comprueba una hipótesis planteada hace tiempo sobre el resultado de una de las dos opciones posibles de evolución que presentaban los tipos de Organizaciones Institucionales en Mutación en las tipologías cooperativas propuestas por Lattuada y Renold (2004). Finalmente, como actor destacado del desarrollo territorial local y regional que culmina en un escenario de crisis irreversible, y dada la envergadura alcanzada por la organización, el impacto de su desmembramiento, enajenación y cambio de naturaleza cooperativa, deja enseñanzas y abre numerosos interrogantes sobre sus efectos en la cadena de valor láctea y en el desarrollo de las comunidades donde se encuentra inserta.
The case study of SanCor Cooperativas Unidas Limitada is relevant due to several reasons. First of all, SanCor Cooperativas Unidas Limitada has got a big economic and social importance in the national milk production sector as well as in provincial towns located in the three major Argentine provinces: Santa Fe, Córdoba and Buenos Aires. Secondly, it is an example of an evolving organisational process going through different degrees: emerging as a second-degree co-operative society, a century after, it becomes a first-degree co-operative society, and finally, it disposes of almost all of its assets as well as its management to other companies of the dairy sector. Thirdly, its evolution verifies a hyothesis that had been stated long time ago about the results of one of the two possible evolution choices which could be carried out by the types of Everchanging Institutional Organisations, according to the co-operative societies typologies proposed by Lattuada and Renold (2004). Lastly, as a leading actor of territorial development, it ends up with an irreversible crisis scenario. Due to the big size reached by this organisation, the impact of its breakup, its disposal and its change in its cooperative society nature, it teaches us some lessons, and poses numerous questions about its effects on the dairy value chain as well as on the local development of those communities where it is inserted.
