The Broker in Pornography and Violence: Lou Reed in Lulu’s World
2020
The article analyses the literary and cultural layers of Lulu, the album published by Lou Reed in collaboration with Metallica, based on Frank Wedekind’s two modernist dramas: Earth Spirit (1895) and Pandora’s Box (1904). In Reed’s reinterpretation, the two plays become his means through which he enters the area of disturbing perversion and graphic pornography. Consequently, Reeds seems to follow Susan Sontag’s diagnosis according to which the goal of pornographic literature is to disorient and to disturb mental balance. In the case of Lulu, it demonstrates Reed’s strategies of crossing the borders between what is commonly accepted and what is rejected because of its non-normative quality. …
Helppoa vai vaikeaa arvioida? : Yleisten kielitutkintojen suomen kielen arvioijien käsityksiä vironkielisten arvioinnista
2016
Finnish raters’ beliefs about assessing Estonian speakers in a Finnish language test: easy or difficult? This paper aims to contribute to our understanding on rater beliefs and views and to promote transparency in rater’s work in the form of reflection. The paper focuses on professional Finnish raters’ beliefs and views of assessing L1 Estonian speakers in the criteria-referenced Finnish language test of the National Certifi- cates of Language Proficiency test system. Finnish raters (N = 27) were asked via email to shortly reflect on what they find easy and what difficult in rating Estonian speakers’ writing and speaking skills in the Finnish language test. The raters reflected on many issu…
Against all odds : Problem-solving as a skill critical to virtual exchange
2021
Virtual Exchange (VE) brings together groups of learners from different geographical locations and cultural backgrounds to engage them in online intercultural collaboration and interaction. Although VE projects are designed and implemented by educators as part of the students’ educational programmes, they often go beyond the setting of traditional courses offered by higher education institutions. Because of their innovative nature, VEs require the students to leave their comfort zone and think outside the box to develop new creative strategies of communication and collaboration in order to find solutions to problems that crop up in this new learning environment. This presentation showcases …
Applying Axial Symmetries to Historical Silk Fabrics: SILKNOW’s Virtual Loom
2020
Symmetry is part of textile art in patterns and motifs that decorate fabrics, which are made by the interlacement of warp and wefts. Moreover, the 3D representation of fabrics have already been studied by some authors
Damping Provision by Different Virtual Synchronous Machine Schemes
2020
The adoption of virtual synchronous machine (VSM) schemes for the control of power converters is gaining more and more attention both in academia and industry. The VSM control strategies fall into the category of grid-forming converter controls, and they are intended for a range of different applications, providing specific services and different kinds of support to the grid. The paper investigates the possibility of damping provision to the system by VSM power converters. Different schemes are considered and compared, showing the opportunity of the investigated solutions through combined modal and time domain analyses. A specific modification of the power synchronization loop is recognized…
Sensitivity Analysis and Frequency Dynamics of Grid-Connected Converters with Virtual Inertia
2021
For the participation in the frequency control of the system, power converters can be controlled with different strategies and methods, sharing the common concept of virtual inertia capability. In this work, a sensitivity analysis of two main categories of converter controls with virtual inertia is presented. The considered schemes are a grid-following current vector control with additional virtual inertia block and a grid-forming control scheme based on virtual synchronous machine concept. A proper basis for the comparison is first assessed providing an analytical correlation between the control parameters of the two schemes. For the two control strategies, the sensitivity analysis of the …
Virtudes escolares percibidas por estudiantes y docentes ecuatorianos: diferencias según sexo, establecimiento y roles
2020
El objetivo del estudio es evaluar la virtuosidad percibida en organizaciones escolares y las diferencias por tipo de centro educativo (fiscal, municipal); sexo (mujer, hombre) y rol (estudiantes, docentes). Se trató de un estudio instrumental basado en el análisis de la estructura factorial y la fiabilidad de un cuestionario para evaluar virtudes percibidas en escuelas (VPOE); y, de un estudio descriptivo transversal que analizó diferencias por sexo, rol y tipo de organizaciones escolares con relación a las virtudes percibidas. Se trabajó con una muestra de 550 estudiantes (49.28 % mujeres) y 105 docentes (47.62% mujeres). El análisis factorial determinó un modelo de cuatro factores que pe…
CVB3 VP1 interacts with MAT1 to inhibit cell proliferation by interfering with Cdk-activating kinase complex activity in CVB3-induced acute pancreati…
2021
Coxsackievirus B3 (CVB3) belongs to the genus Enterovirus of the family Picornaviridae and can cause acute acinar pancreatitis in adults. However, the molecular mechanisms of pathogenesis underlying CVB3-induced acute pancreatitis have remained unclear. In this study, we discovered that CVB3 capsid protein VP1 inhibited pancreatic cell proliferation and exerted strong cytopathic effects on HPAC cells. Through yeast two-hybrid, co-immunoprecipitation, and confocal microscopy, we show that Menage a trois 1 (MAT1), a subunit of the Cdk-Activating Kinase (CAK) complex involved in cell proliferation and transcription, is a novel interaction protein with CVB3 VP1. Moreover, CVB3 VP1 inhibited MAT…
Infection-induced chromatin modifications facilitate translocation of herpes simplex virus capsids to the inner nuclear membrane
2021
Herpes simplex virus capsids are assembled and packaged in the nucleus and move by diffusion through the nucleoplasm to the nuclear envelope for egress. Analyzing their motion provides conclusions not only on capsid transport but also on the properties of the nuclear environment during infection. We utilized live-cell imaging and single-particle tracking to characterize capsid motion relative to the host chromatin. The data indicate that as the chromatin was marginalized toward the nuclear envelope it presented a restrictive barrier to the capsids. However, later in infection this barrier became more permissive and the probability of capsids to enter the chromatin increased. Thus, although …
Biochemical and structural analysis of the NS5B RNA-dependent RNA polymerase of the hepatitis C virus.
2000
Hepatitis C virus (HCV), the major causative agent of chronic and sporadic non-A, non-B hepatitis worldwide, is a distinct member of the Flaviviridae virus family. These viruses have in common a plus-strand RNA genome that is replicated in the cytoplasm of the infected cell via minus-strand RNA intermediates. Owing to the lack of reliable cell culture systems and convenient animal models for HCV, the mechanisms governing RNA replication are not known. As a first step towards the development of appropriate in vitro systems, we expressed the NS5B RNA-dependent RNA polymerase (RdRp) in insect cells, purified the protein to near homogeneity and studied its biochemical properties. It is a primer…
