Women on the Path of the Goddess: Sacred Technologies of the Everyday
Authors: Trulsson Åsa
Published: May 2020

Contemporary spiritualties are often portrayed as a turn to a subjective and individualized form of religion, consisting of individually held truth claims or private peak experiences that are generated sporadically at retreats and workshops. The portrayal is ultimately related to a perception of everyday life in contemporary Euro-America as mundane, rationalized, and secular, but also the exclusion of practices centered on the body, the home and the everyday from what is deemed properly religious. This article explores the sacred technologies of the everyday among women in England who identify as Goddess worshippers. The purpose is to further the understanding of religion and the everyday, as well as the conceptualization of contemporary Goddess-worship as lived religion. Through examining narratives on the intersection between religion and everyday activities, the technologies of imbuing everyday life with a sacred dimension become visible. The sacred technologies imply skills that enable both imagining and relating to the sacred. The women consciously and diligently work to cultivate skills that would allow them to sense and make sense of the sacred, in other words, to foster a sense of withness through the means of a host of practices. I argue that the women actively endeavor to establish an everyday world that is experienced as inherently different from the secular and religious fields in their surroundings; hence it is not from disenchantment or an endeavor with no social consequences. The women’s everyday is indeed infused with different strategies where the body, different practices, and material objects are central in cultivating a specific religious disposition that ultimately will change the way the women engage with and orient themselves in the world.
Hocus POCUS—Using the Magic of Ultrasound to Look Inside the Body
Authors: El-Baba Mazen , Jamnik Joseph , Heslop Claire
Published: May 2020

Ultrasound machines use sound waves to take a look inside your body. These sound waves are very high pitched and cannot be heard or felt. They are generated by an ultrasound machine that uses crystals at the end of an ultrasound probe. These waves pass through your skin and as they reflect back to the machine from tissues in your body, the machine turns them into an image. In this article, you will learn about the different uses of ultrasound, like seeing babies inside the uterus or examining important body organs in patients who are feeling sick. You will also learn about the safety of ultrasound in case you ever need to get one. Last, we will explore the future of ultrasound in medicine by learning about point-of-care ultrasound, or POCUS, which is making it easier for children and grownups to get ultrasounds when they need them!
Discrete Element Analysis of the Strength Anisotropy of Fiber-Reinforced Sands Subjected to Direct Shear Load
Authors: Gong Linxian , Nie Lei , Xu Yan
Published: May 2020

Soil reinforcement with natural or synthetic fibers enhances its mechanical behavior in various applications. Fiber-reinforced sands (FRS) can be relatively anisotropic because of the fiber self-weight and the compaction technique. However, the microscopic mechanisms underlying the anisotropy are still poorly understood. This study used a discrete element approach to analyze the microscopic mechanisms underlying the strength anisotropy of FRS due to fiber orientation. Analysis of contact networks revealed that the optimum fiber orientation angle is perpendicular to the main direction of strong contact force in direct shear testing. These fibers produced the largest increase in shear zone thickness, normal force around the fiber body, effective contact area, tensile force along fibers, and energy storage/dissipation. This study is valuable for further understanding of the mechanical behaviors of FRS.
On the Binormal Predictive Receiver Operating Characteristic Curve for the Joint Assessment of Positive and Negative Predictive Values
Authors: Hughes Gareth
Published: May 2020

The predictive receiver operating characteristic (PROC) curve is a diagrammatic format with application in the statistical evaluation of probabilistic disease forecasts. The PROC curve differs from the more well-known receiver operating characteristic (ROC) curve in that it provides a basis for evaluation using metrics defined conditionally on the outcome of the forecast rather than metrics defined conditionally on the actual disease status. Starting from the binormal ROC curve formulation, an overview of some previously published binormal PROC curves is presented in order to place the PROC curve in the context of other methods used in statistical evaluation of probabilistic disease forecasts based on the analysis of predictive values; in particular, the index of separation (PSEP) and the leaf plot. An information theoretic perspective on evaluation is also outlined. Five straightforward recommendations are made with a view to aiding understanding and interpretation of the sometimes-complex patterns generated by PROC curve analysis. The PROC curve and related analyses augment the perspective provided by traditional ROC curve analysis. Here, the binormal ROC model provides the exemplar for investigation of the PROC curve, but potential application extends to analysis based on other distributional models as well as to empirical analysis.
Undergraduates Interested in STEM Research Are Better Students than Their Peers
Authors: Bickford Nate , Peterson Elizabeth , Jensen Philip , Thomas Dave
Published: May 2020

In Science, Technology, Engineering, and Mathematics (STEM), undergraduate research experiences provide students with invaluable opportunities to improve scientific skills. However, less is known about its impact on higher-order thinking skills. Therefore, we sought to determine if engagement in undergraduate research would improve academic performance in students engaged in research compared to those that were not. To accomplish this, biology majors were enrolled in courses that taught research methodology and techniques. Results indicated that students who were selected for the research program outperformed their peers in their other classes during the research program, based on t-test statistics. However, these students had also outperformed their peers during the previous fall semester, prior to receiving additional instruction. Furthermore, students who merely applied for inclusion in the program had significantly higher grades than students who did not apply. In addition, writing samples from research and non-research students were significantly different. Taken together, these data suggest that while undergraduate research may indeed enhance a student’s academic performance and interest in science, a student’s personal interest and drive for research may themselves indicate superior academic performance. Further, science departments aiming to offer research early in their curricula may benefit from such a self-selection strategy, especially in cases where there are limited resources available for undergraduate research.

Published: May 2020

In relation to the use of retrofit materials on damaged constructions, application on earthquake-resistant buildings, and for the strengthening and rehabilitation on weakened regions, there is a need for a more superior material than concrete. Application sites include beam-column joints, corbels, link-slabs, deep beams, support regions and dapped-end areas. Fiber reinforced engineered cementitious composites (FR-ECC) can address this issue, because FR-ECC is one of the composite materials that has high strength, ductility and durability. In order to develop FR-ECC, this study was done to investigate the effect of adding quartz powder on the compressive strength capacity and properties of FR-ECC through the use of polyvinyl alcohol (PVA) and steel fibers. The volume fraction of fiber was set to 0%–2%. To support the friendly environment, FR-ECC uses by-product materials such as fly ash and silica fume, with a cement content less than 600 kg/m3. In terms of the experimental investigation on FR-ECC, this work conducted the fresh property tests showing that PVA fibers have quite an influence on ECC workability, due to their hydrophilic behavior. By adjusting the superplasticizer (SP) content, the consistency and high workability of the ECC mixes have been achieved and maintained. The test results indicated that the PVA and steel fibers-based ECC mixes can be classified as self-compacting composites and high early compressive strength composites. Significantly, addition of quartz powder into the ECC mixes increased the compressive strength ratio of the ECC samples up to 1.0747. Furthermore, the steel fiber-based ECC samples exhibited greater compressive strength than the PVA fibers-based ECC samples with the strength ratio of 1.1760. Due to effect of the pozzolanic reaction, the fibers dispersion and orientation in the fresh ECC mixes, so that the cementitious matrices provided the high strength on the FR-ECC samples. During the compression loading, the bulging effect always occurred before the failures of the fibers-based ECC samples. No spalling occurred at the time of rupture and the collapse occurred slowly. Thus, FR-ECC has provided unique characteristics, which will reduce the high cost of maintenance.
Experimental Research on the Behavior of the Rail Seat Section of Different Types of Prestressed Concrete Sleepers

Published: May 2020

Nowadays, prestressed concrete sleepers are the most common type of sleepers. In different countries all over the world prestressed concrete sleepers are designed with different shapes, with different types of prestressed reinforcement and arrangements in cross-section. Additionally, different manufacturing methods and techniques are used for prestressed concrete sleepers. These railway members are stiff, durable and can withstand heavy loads. Despite that, damaged or deteriorated prestressed concrete sleepers appear on railway tracks even before the end of their service life. Therefore, there is a need for better understanding of the behavior of different types of prestressed concrete sleepers to optimize their design. The rail seat section of the sleeper is the most affected part of sleeper. Therefore, analysis of experimental results of bearing capacity, cracking, and deformation of the rail seat section of sleeper under static and dynamic loads are provided in this article. Furthermore, different types, diameters, and anchoring methods of prestressed reinforcement were analyzed in this article. Additionally, comparison of experimental results of different types of prestressed concrete sleepers is discussed.

Published: May 2020

This paper describes an optimization study of a spherical composite submersible pressure hull employing a genetic algorithm (GA) in ANSYS. A total of five lay-up arrangements were optimized for three unidirectional composites carbon/epoxy, glass/epoxy, and boron/epoxy. The minimization of the buoyancy factor ( B . F ) was selected as the design optimization objective. The Tsai-Wu and Tsai-Hill failure criteria and buckling strength factor ( λ ) were used as the material failure and instability constraints. To determine the effect of geometric non-linearity and imperfections on the optimized design, a non-linear buckling analysis was also carried out for one selected optimized design in ABAQUS. The non-linear buckling analysis was carried out using the modified RIKS procedure, in which the imperfection size changed from 1 to 10 mm. A maximum decrease of 65.937% in buoyancy factor ( B . F ) over an equivalent spherical steel pressure hull was computed for carbon/epoxy. Moreover, carbon/epoxy displayed larger decreases in buoyancy factor ( B . F ) in the case of 4 out of a total of 5 lay-up arrangements. The collapse depth decreased from 517.95 m to 412.596 m for a 5 mm lowest mode imperfection. Similarly, the collapse depth decreased from 522.39 m to 315.6018 for a 5 mm worst mode imperfection.

The recent outbreak of the Coronavirus disease 2019 (COVID-19) has quickly spread worldwide since its discovery in Wuhan city, China in December 2019. A comprehensive strategy, including surveillance, diagnostics, research, clinical treatment, and development of vaccines, is urgently needed to win the battle against COVID-19. The past three unprecedented outbreaks of emerging human coronavirus infections at the beginning of the 21st century have highlighted the importance of readily available, accurate, and rapid diagnostic technologies to contain emerging and re-emerging pandemics. Real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) based assays performed on respiratory specimens remain the gold standard for COVID-19 diagnostics. However, point-of-care technologies and serologic immunoassays are rapidly emerging with high sensitivity and specificity as well. Even though excellent techniques are available for the diagnosis of symptomatic patients with COVID-19 in well-equipped laboratories; critical gaps still remain in screening asymptomatic people who are in the incubation phase of the virus, as well as in the accurate determination of live viral shedding during convalescence to inform decisions for ending isolation. This review article aims to discuss the currently available laboratory methods and surveillance technologies available for the detection of COVID-19, their performance characteristics and highlight the gaps in current diagnostic capacity, and finally, propose potential solutions. We also summarize the specifications of the majority of the available commercial kits (PCR, EIA, and POC) for laboratory diagnosis of COVID-19.
Shedding Light on the Role of Extracellular Vesicles in HIV Infection and Wound Healing
Authors: Alqatawni Aseel , Sharma Adhikarimayum Lakhikumar , Attilus Beatrice , Tyagi Mudit , Daniel Rene
Published: May 2020

Extracellular vesicles (EVs) play an important role in intercellular communication. They are naturally released from cells into the extracellular environment. Based on their biogenesis, release pathways, size, content, and function, EVs are classified into exosomes, microvesicles (MVs), and apoptotic bodies (ApoBDs). Previous research has documented that EVs, specifically exosomes and MVs, play an important role in HIV infection, either by promoting HIV infection and pathogenesis or by inhibiting HIV-1 to a certain extent. We have also previously reported that EVs (particularly exosomes) from vaginal fluids inhibit HIV at the post-entry step (i.e., reverse transcription, integration). Besides the role that EVs play in HIV, they are also known to regulate the process of wound healing by regulating both the immune and inflammatory responses. It is noted that during the advanced stages of HIV infection, patients are at greater risk of wound-healing and wound-related complications. Despite ongoing research, the data on the actual effects of EVs in HIV infection and wound healing are still premature. This review aimed to update the current knowledge about the roles of EVs in regulating HIV pathogenesis and wound healing. Additionally, we highlighted several avenues of EV involvement in the process of wound healing, including coagulation, inflammation, proliferation, and extracellular matrix remodeling. Understanding the role of EVs in HIV infection and wound healing could significantly contribute to the development of new and potent antiviral therapeutic strategies and approaches to resolve impaired wounds in HIV patients.

Published: May 2020

Baropodometrijom se mjerio tlak stopala na površinu tijekom stajanja. Čovječje stopalo prilikom kontakta s podlogom po kojoj se giba uzrokuje silu reakcije. Pomoću plantografa i pur pjene mjerila se dužina stopala te pritisak i sile koje se javljaju između stopala i površine. Istoimeni uređaj našao je veliku primjenu u erogonomiji prvenstveno kod izrade standardnih uložaka za obuću. U cilju što vjernije izrade ortopedskih uložaka i cipela, stopalo ostavlja otisak sa posebno naglašenim uporišnim točkama. U radu je izvršena usporedba pritiska normalnog i deformirang stopala kod muškaraca i žena u odnosu na težinu njihovih tijela. Analizom je dobiveno da deformirano stopalo proizvodi sveukupno veći tlak plantarnog tkiva od normalnog stopala. To djelomično pojašnjava teškoće i nepravilnosti u hodu s kojima se ljudi svakodnevno susreću. Ovim istraživanjem ispitanicima se mjerila težina, visina te površina stopala kod 10 muškaraca i 10 žena sa zdravim i deformiranim stopalom. Nadalje, mjerilo se sila i tlak koje stopalo proizvede hodajući. Promatrajući uporište točke na koje se stopalo oslanja došlo je do zaključka da osobe sa većom težinom proizvedi veći tlak stopala, stvaraju veću silu na podlogu, neovisno o spolu pojedinca. U nadi da će ovo istraživanje pridonijeti večoj proizvodnji ergonomske obuće da bih smanjili opterećenje stopala jer oni su ipak ˝naši mali nosači velikog tereta˝.
Age determination of Precambrian rocks from Greenland: past and present
Authors: Kalsbeek Feiko
Published: May 2020

Age determination is an essential part of many geological investigations. The ages of Phanerozoic sedimentary rocks are typically determined by palaeontological studies (often with high precision), but for Precambrian rocks as well as for younger igneous intrusions, precise ages can only be obtained by isotopic analysis of minerals or rocks. Isotopic (radiometric) age determination of Greenland rocks began in the early 1960s and has continued since with gradually improving methods. In this contribution, the development of geochronological knowledge of the Precambrian of Greenland is described in historical perspective, and an outline of new results is given. The history of geochronology can be roughly divided into three periods: 1) a period of single-sample K-Ar and Rb-Sr mineral or whole-rock age determinations; 2) a time when most ages were determined with the help of Rb-Sr and Pb-Pb whole-rock isochrons and multi-grain zircon U-Pb isotope data; 3) the present, where ‘single’ zircon U-Pb data are the preferred method to obtain rock ages. These stages in the development of radiometric dating methods partly overlap in time, and each has yielded very significant contributions to the knowledge of Precambrian evolution in Greenland.

The 1997 summer season saw continued petroleum geological activities in the Disko–Nuussuaq–Svartenhuk Halvø area, onshore West Greenland. These activities mainly took the form of a geological field project led by the Geological Survey of Denmark and Greenland (GEUS), whereas the continued exploration by grønArctic Energy Inc. (grønArctic) in the third year of their licence was kept at a very low level without field work, geophysical surveys or drilling. Furthermore an airborne geophysical survey, Aeromag 1997, covering a large part of the Disko Bugt area, was carried out in the early summer of 1997 with GEUS as project manager (Stemp 1997; Stemp & Thorning 1998, this volume).
New structure maps over the Nuussuaq Basin, central West Greenland

Published: May 2020

In 1992 the Geological Survey of Greenland (GGU) discovered bitumen in vugs and vesicles in Upper Paleocene basalts in western Nuussuaq (Christiansen et al. 1994). Since then the search for surface oil showings by GGU (from 1995 by the Geological Survey of Denmark and Greenland, GEUS) has resulted in finds over an area extending from northern Disko through Nuussuaq to the south-east corner of Svartenhuk Halvø (Christiansen et al. 1997, 1998, this volume). In addition, slim core drilling by GGU and grønArctic Energy Inc., the holder of an exclusive licence in western Nuussuaq, penetrated oil-saturated rocks at four localities (Christiansen et al. 1996). Encouraged by these results, grønArctic drilled a conventional exploration well (GRO#3) to 2996 m in 1996 (Christiansen et al. 1997), but details about this have not been released. The net effect of these efforts has been to dispel partially the formerly widespread view that the West Greenland area is entirely gas-prone and to promote the Cretaceous– Tertiary Nuussuaq Basin from being a model for what may occur in offshore basins to being a potential petroleum basin in its own right. Evolving conceptions of the Nuussuaq Basin took a large step forward when GGU in 1994 acquired a 13 km 15-fold seismic line on the south coast of Nuussuaq (Christiansen et al. 1995). This showed a sedimentary section 6–8 km thick, much greater than the 2–3 km previously measured from onshore outcrops alone. This showed how little was understood about the structure of the basin, as well as where hydrocarbons might have been generated and where exploration could best be directed. A first step to rectify this situation was taken in 1995 when multichannel seismic and gravity data were acquired by the Survey in Disko Bugt and the fjords north and south of Nuussuaq, as well as west of Disko (Christiansen et al. 1996). The new data have been integrated with older gravity, magnetic and seismic data from both onshore and offshore. This report summarises the results of interpretation of all available geophysical data together with a reappraisal of all available data on faults onshore. Detailed accounts are being published elsewhere (Chalmers 1998; J.A. Chalmers et al. unpublished data). Although the open spacing of the seismic lines and the almost total lack of reflections below the first sea-bed multiple on these lines make it impossible to present a definitive structural model at this stage, the structural style in the basin is now apparent and a number of the major structures in the area have been identified with confidence.
Airborne geophysical surveys in central West Greenland and central East Greenland in 1997
Authors: Thorning Leif , Stemp Robert W.
Published: May 2020

In order to stimulate mining exploration activity in Greenland the Government of Greenland decided in 1993 to finance a five-year programme of airborne electromagnetic surveys over selected regions of Greenland, Project AEM Greenland 1994–1998. By the end of 1996 three surveys had been undertaken in various parts of Greenland (Stemp & Thorning 1995a, b; Stemp 1996a, b; Stemp 1997a, b). In 1992 the Danish Government financed a small aeromagnetic survey (Project Aeromag 1992; Thorning 1993). Regional aeromagnetic surveying was taken up again when the governments of Denmark and Greenland jointly financed two aeromagnetic surveys in 1995 and 1996 – the projects Aeromag 1995 and Aeromag 1996 (Thorning & Stemp 1997). To this suite of airborne geophysical surveys of selected regions in Greenland were added two surveys in 1997, both financed by the Government of Greenland. The fourth year of Project AEM Greenland 1994–1998 encompassed a transient electromagnetic (GEOTEM) and magnetic survey over northern Jameson Land, central East Greenland, while Project Aeromag 97 added a regional aeromagnetic survey over Disko Bugt – Nuussuaq, central West Greenland. As in previous years, commercial geophysical contractors carried out the survey operations in Greenland according to an agreement with the Geological Survey of Denmark and Greenland (GEUS) entered into after international tendering following rules of the European Union. GEUS manages the projects and organises the distribution and use of the results. The new maps and digital data from the two 1997 surveys, a total of 85 252 line kilometres of data covering 51 414 km2, were released to the public on 1 March 1998. This note provides some introductory information about the two surveys. Further information can be found in reports by Stemp (1998) and Thorning (in press); both include a number of full-page colour anomaly maps from the survey areas.

The airborne geophysical programme will continue in 1998, and the areas to be surveyed have already been selected. The final year of Project AEM Greenland 1994–1998 will include combined GEOTEM and magnetic surveys over two regions in North Greenland: Washington Land in western North Greenland, where operations are expected to start in May 1998 operating out of Alert in Canada, and later in the season over J.C. Christensen Land in central North Greenland operating out of Station Nord in eastern North Greenland. Project Aeromag 1998 will continue the regional aeromagnetic survey programme in West Greenland, extending the coverage by including most of the region from 63°45′N to 66°N in southern West Greenland. This project will be based at Nuuk and start in March 1998. The Government of Greenland will finance all surveys in 1998. Figure 1 shows all survey areas for the electromagnetic and magnetic surveys of Project AEM Greenland 1994–1998 and the aeromagnetic survey areas of Project Aeromag 1992, 1995, 1996, 1997 and 1998.
Hydrothermal activity in the Upper Permian Ravnefjeld Formation of central East Greenland – a study of sulphide morphotypes
Authors: Kresten Nielsen Jesper , Pedersen Mikael
Published: May 2020

Bituminous shales of the Ravnefjeld Formation were deposited in the subsiding East Greenland basin during the Upper Permian. The shales are exposed from Jameson Land in the south (71°N; Fig. 1) to Clavering Ø in the north (74°20′N) and have attracted considerable attention due to their high potential as hydrocarbon source rocks (Piasecki & Stemmerik 1991; Scholle et al. 1991; Christiansen et al. 1992, 1993a, b). Furthermore, enrichment of lead, zinc and copper has been known in the Ravnefjeld Formation on Wegener Halvø since 1968 (Lehnert-Thiel 1968; Fig. 1). This mineralisation was assumed to be of primary or early diagenetic origin due to similarities with the central European Kupferschiefer (Harpøth et al. 1986). Later studies, however, suggested base metal mineralisation in the immediately underlying carbonate reefs to be Tertiary in age (Stemmerik 1991). Due to geographical coincidence between the two types of mineralisation, a common history is a likely assumption, but a timing paradox exists. A part of the TUPOLAR project on the ‘Resources of the sedimentary basins of North and East Greenland’ has been dedicated to re-investigation of the mineralisation in the Ravnefjeld Formation in order to determine the genesis of the mineralisation and whether or not primary or early diagenetic base metal enrichment has taken place on Wegener Halvø, possibly in relation to an early period of hydrothermal activity. One approach to this is to study the various sulphides in the Ravnefjeld Formation; this is carried out in close co-operation with a current Ph.D. project at the University of Copenhagen, Denmark. Diagenetically formed pyrite is a common constituent of marine shales and the study of pyrite morphotypes has previously been successful from thermalli immature parts of elucidating depositional environment and thermal effects in the Alum Shale Formation of Scandinavia (Nielsen 1996; Nielsen et al. 1998). The present paper describes the preliminary results of a similar study on pyrite from thermally immature parts of the Ravnefjeld Formation which, combined with the study of textures of base metal sulphides in the Wegener Halvø area (Fig. 1), may provide an important step in the evaluation of the presence or absence of early thermal activity on (or below) the Upper Permian sea floor.
An Archaean sill complex and associated supracrustal rocks, Arveprinsen Ejland, north-east Disko Bugt, West Greenland
Authors: Marshall Brian , Schønwandt Hans Kristian
Published: May 2020

Archaean supracrustal rocks on Arveprinsen Ejland comprise maﬁc and felsic volcanic rocks overlain by an epiclastic sedimentary sequence invaded by a maﬁc to ultramaﬁc sill complex. The latter has a strike-length of 7500 m and a cumulative preserved thickness of 2000–2500 m and amounts to nearly 50% of the exposed thickness of the supracrustal rocks. Chilled and locally peperitic contacts are developed between component sills and the inter-sill metasedimentary septa. The sub-alkalic sill complex and maﬁ c lavas and tuffs are high-magnesium tholeiites and basaltic komatiites whereas the felsic rocks are calc-alkaline rhyolites and dacites. Chondrite- and MORB-normalised spider diagrams afﬁrm the close similarity of the maﬁc volcanic rocks and the sill complex; they are also consistent with a tholeiitic or komatiitic afﬁnity. Tectonomagmatic discrimination plots suggest an ensialic arc-related setting for the sill complex and the maﬁc and felsic volcanic rocks. The sill complex was progressively emplaced, as an upward-younging sequence of component sills, beneath 2 to 2.5 km of seawater and substantially less than 0.5 km of wet sediment. Sills formed when the magmatic pressure exceeded the effective overburden pressure of the sediment plus the vertical tensile strength (To) of the host materials. Intrusion was probably promoted by the drop in To at the interface between contact-lithiﬁed and poorly lithiﬁed strata. The thickness of the sill complex was accommodated by dilational lifting plus the capacity of an intrusion to create space through expulsion of water from wet sediment.
Albitised gneisses in the area between Paakitsoq and Kangerluarsuk, north-east Disko Bugt, West Greenland

Published: May 2020

Fine-grained rutile-bearing albite-rich rocks (> 95% albite) locally replace Archaean granodioritic orthogneisses in the area between Paakitsoq and Kangerluarsuk, eastern Disko Bugt. They occur as anastomosing networks within albite-rich gneiss and as replacements along linear fracture zones. Albitisation resulted from pervasive metasomatism, but the origin and nature of the albitising ﬂuids are uncertain. A tentative comparison is made with rutile-rich albitites (‘kragerøites’) in southern Norway.
Proterozoic tectonic overprinting of Archaean gneisses in Nuussuaq, West Greenland
Authors: Garde Adam A. , Steenfelt Agnete
Published: May 2020

Archaean orthogneisses and supracrustal rocks in eastern Nuussuaq in the southern part of the Rinkian orogen preserve much indirect evidence of Proterozoic reworking. In northern Nuussuaq, a marble occurrence which can be correlated with the Proterozoic Mârmorilik Formation of the Uummannaq district, is interleaved and intensely folded with Archaean orthogneisses. Dykes and sills of presumed Proterozoic age in southern Nuussuaq pre-date two major shear zones. Furthermore, published K-Ar and 40Ar-39Ar hornblende ages indicate that metamorphic temperatures of at least c. 550°C were reached in large parts of Nuussuaq during the Proterozoic. Although available data are not sufﬁcient to ﬁrmly establish the tectonic evolution of Nuussuaq, it can be shown that development of a regional ﬂat-lying structure was succeeded ﬁrst by upright folding and development of a major NW–SE-trending shear zone during crustal shortening, and subsequently by formation of an ENE–WSW-trending shear zone during crustal extension. A Rinkian detachment zone across Nuussuaq, similar to those known in the Uummannaq district, may link Proterozoic marble occurrences south of the peninsula with the marbles known in northern Nuussuaq and in the Uummannaq district. Observations suggest that geological structures and lithologies can be traced from north to south across the fjord Torsukattak, into the Ataa area which is hardly affected by Proterozoic deformation. This is used to infer that a major crustal boundary structure along the fjord (previously assumed to form the northern boundary of the Burwell terrane in West Greenland) does not exist.
Story-telling as memorialisation
Authors: Green Simon , Kondor Katherine , Kidd Alicia
Published: May 2020

Is there a relationship between story-telling and memorialisation in the construction of victim identities? This paper seeks to examine these questions and shed light on the cultural dynamics of victimisation with reference to examples from sociological theories of late modernity and empirical research with people who self-identify as victims. Using examples from recent biographic interviews with an asylum seeker fleeing conflict in Gaza and two Hungarian radical right activists, the argument will be that victim identities are constructed and reconstructed through the development of personal and mediatised narratives about suffering and resilience.
How rewatching video lectures impacts students’ performance in assessments in MOOCs

Published: May 2020

Recorded video lectures are a core instructional tool in MOOCs. Students value video lectures and rank rewatching them as an important activity they use to prepare for assessments. Platforms promote rewatching video lectures as an essential instrument of preparation. Despite the widespread use of this strategy, we understand very little about how rewatching video lectures impacts students’ performance. In this study, we assess the overall effect of rewatching video lectures on students’ performance retaking assessments, and the individual differences among items within the assessment. We use a cross-classification multilevel logistic approach with fixed and random effects of rewatching video lectures and apply the approach to four courses on the Coursera platform. We found that the overall effect varies over courses and among items within an assessment: it can take positive, null, and negative values. Our conclusion is caution: the generalized recommendation that students rewatch videos before they retake a failed assessment is not an absolute truth. Individual students behave differently in a given assessment situation, and more research is needed to better understand student success.

Abstract : Bullying is a social problem that is often found among school children. This phenomenon continues to increase in numbers in Indonesia. Weak supervision from parents, educators, and the community is one of the factors causing the outbreak of bullying in the school environment, in addition to the fact that victims do not dare to fight or report. This has resulted in cases of bullying that can not be handled properly so that it gives the impact of depression, feelings of worthless and unaccepted, and changes in the victim's self-concept. This study aims to analyze the effect of bullying on adolescent self-concept at Kendedes Health Vocational School. The design used was observational analytic with cross sectional study approach. The study was conducted at Kendedes Health Vocational School with a sample of 56 students selected using purposive sampling techniques. Analysis of data using linear regression. The results showed that bullying had an influence on adolescent self-concept (r = 0.242), with an effect of 5.8% (R Square = 0.058). This means that self-concept is influenced by 94.2% by other variables not examined. It takes attention and awareness of the school and students to avoid cases of bullying in schools. Further research is expected to strengthen the results of this study.Keywords : bullying, self-concept, adolescentAbstrak : Bullying merupakan salah satu masalah sosial yang banyak ditemukan di kalangan anak sekolah.

Over the past decade, significant efforts have been made to improve the trade-off between speed and accuracy of surface normal estimators (SNEs). This paper introduces an accurate and ultrafast SNE for structured range data. The proposed approach computes surface normals by simply performing three filtering operations, namely, two image gradient filters (in horizontal and vertical directions, respectively) and a mean/median filter, on an inverse depth image or a disparity image. Despite the simplicity of the method, no similar method already exists in the literature. In our experiments, we created three large-scale synthetic datasets (easy, medium and hard) using 24 3-dimensional (3D) mesh models. Each mesh model is used to generate 1800--2500 pairs of 480x640 pixel depth images and the corresponding surface normal ground truth from different views. The average angular errors with respect to the easy, medium and hard datasets are 1.6 degrees, 5.6 degrees and 15.3 degrees, respectively. Our C++ and CUDA implementations achieve a processing speed of over 260 Hz and 21 kHz, respectively. Our proposed SNE achieves a better overall performance than all other existing computer vision-based SNEs. Our datasets and source code are publicly available at: sites.google.com/view/3f2n.
