Fokus på informationskompetence i et tværfagligt læringsmiljø - et empirisk studie af læringseffekter og studenterperspektiver
Authors: Overgaard Charlotte , Grundsøe Mette Buje 
Published: September 2021

Der har i en årrække indenfor de videregående uddannelser været fokus på, at studerendes udvikling af informationskompetence og læring igennem problemorienteret projektarbejde er tæt forbundet, og at et nært samarbejde mellem bibliotek og uddannelsesmiljø er en væsentlig forudsætning for studerendes læring. I praksis er der dog en række forhold, som kan hindre et effektivt samarbejde mellem bibliotek og uddannelse og bevirke, at de pædagogiske intentioner ikke indfries. I et tværfagligt samarbejde mellem universitetsbibliotek og fagmiljø blev der i 2012 i forbindelse med opstarten af en ny 2-årig kandidatuddannelse i Folkesundhedsvidenskab ved Aalborg Universitet udviklet et undervisningsforløb og en række læringsunderstøttende tiltag som obligatorisk anvendelse af søgebilag i projekter og tværfaglige søgeworkshops, baseret på teorier om problembaseret læring og tilrettelæggelse af søge-læreprocesser. På baggrund af empiriske data fra informationssøgningstest, studenterprojektrapporter og gruppeinterviews undersøges effekten af undervisningen på de studerendes udvikling af informationskompetence samt deres perspektiver på læringsunderstøttende tiltag. Der identificeres fremmende og hæmmende faktorer ift. udvikling af informationskompetence og afslutningsvis diskuteres styrker og svagheder samt hvilke forhold, som er centrale – og også relevante i en bredere universitetspædagogisk sammenhæng – hvis informationskompetence skal integreres som del af de studerendes grundlæggende faglighed. Learning through problem-based project-work and the development of information literacy skills has become increasingly common in higher education programmes in recent years. It is also generally acknowledged that these learning experiences benefit from close collaboration between university libraries and their educational environments. There is evidence to suggest, however, that a number of conditions can hamper the effective collaboration between library and study programme and so leave the educational intentions unfulfilled. A new Master’s programme in Public Health that was introduced at Aalborg University in 2012 aims to address these shortcomings by turning theories of problem-based learning and searching-learning processes into teaching activities as a result of a close inter-disciplinary collaboration between university library and academic environment. This paper examines the effect of and student perspectives on the developed teaching activities. A combination of information seeking tests, student project reports and group interviews provided the empirical data for the study. These revealed a number of promotive and inhibitory factors in connection with the development of information literacy skills. The strengths and weaknesses are discussed in this paper, along with the educational and pedagogical key points that are important if information literacy is to become a part of the students’ basic academic skill set.

The Hypocrisy of Dutch Actions in Indonesia
Authors: Keil Julie A. 
Published: September 2021

At the end of World War 2 the Netherlands, through its own military tribunals, tried and convicted several members of the Japanese and German militaries for their participation in the war crime of extra judicial executions in Indonesia and the Netherlands. Several of the convicted men were executed by the Netherlands while others sentenced to lengthy prison terms. From 1946-1949 the Netherlands, primarily through commando Raymond Westerling, engaged in the same actions they accused the Japanese of having committed. While no specific order was ever revealed showing that Westerling’s actions were ordered by the military, the Netherlands tacitly approved his actions by failing to control him and his men and by their unwillingness to take responsibility for his actions before or after the Netherlands withdrew its forces from Indonesia in 1949. This research paper explores the extrajudicial executions conducted by Westerling, his men, other Dutch military and the Dutch government in order to provide a better and more thorough understanding of these events and the lack of national or international action against war crimes committed after World War 2. It concludes that the Netherlands has failed to try or even accuse Westerling and others of war crimes or take actions to discipline them, and in fact has covered up his actions and failed to make public those war crimes. Further that the reason for this continued hypocritical refusal is a concern for the reputation of the Netherlands in the world and a belief that high levels of government would be found complicit.

AbstractEutectic gallium‐indium (EGaIn) liquid metal droplets have been considered as a suitable platform for producing customized 3D composites with functional nanomaterials owing to their soft and highly reductive surface. Herein, the synthesis of a 3D plasmonic oxide framework (POF) is reported by incorporating the ultra‐thin angstrom‐scale‐porous hexagonal molybdenum oxide (h‐MoO3) onto the spherical EGaIn nanodroplets through ultrasonication. Simultaneously, a large number of oxygen vacancies form in h‐MoO3, boosting its free charge carrier concentration and therefore generating a broad surface plasmon resonance across the whole visible light spectrum. The plasmonic chemical sensing properties of the POF is investigated by the surface‐enhanced Raman scattering detection of rhodamine 6G (R6G) at 532 nm, in which the minimum detectable concentration is 10−8 m and the enhancement factor reached up to 6.14 × 106. The extended optical absorption of the POF also allowed the efficient degradation of the R6G dye under the excitation of ultraviolet‐filtered simulated solar light. Furthermore, the POF exhibits remarkable photocurrent responses towards the entire visible light region with the maximum response of ≈1588 A W−1 at 455 nm. This work demonstrates the great potential of the liquid metal‐based POFs for high‐performance sensing, catalytic, and optoelectronic devices.

AbstractInspired by natural redwood and bone, a biomimetic strategy is presented to develop a highly bioactive redwood‐like nanocomposite via radial freeze casting of biocompatible hydrogels followed by the in situ coprecipitation of a Si‐containing CaP hybrid nanocoating (SCPN). The engineered material displays radially aligned macrochannels and a porous network structure similar to those of natural redwood. In addition to acting as a mechanical reinforcement, introducing SCPNs into the weak redwood‐like scaffold yields not only a nanoroughened surface topography, a low swelling ratio, retarded enzymatic degradation, and enhanced protein absorption abilities but also the sustained sequential release of Si and Ca ions, thereby providing essential biophysical and biochemical cues for effective bone regeneration. Benefiting from the redwood‐like structures and bioactive SCPNs, the biomimetic materials create a favorable microenvironment for promoting the initial adhesion, spreading, proliferation, and migration of bone marrow‐derived mesenchymal stem cells and human umbilical vein endothelial cells. Furthermore, the in vitro and in vivo data showed that the biocompatible redwood‐like scaffold with precipitated SCPN can synergistically promote osteogenesis and angiogenesis in their aligned direction. Collectively, this work presents a novel bioinspired redwood‐like material with multifunctional properties that provides new insight into bone defect repair.

AbstractPhotogenerated charge separation and directional transfer to active sites are pivotal steps in photocatalysis, which limit the efficiency of redox reactions. Here, a conductive network and dipole field are employed to harness photogenerated charge kinetics by using a Ti3C2/TiO2 network (TTN). The TTN exhibits a prolonged charge‐carrier lifetime (1.026 ns) and an 11.76‐fold increase in hexavalent chromium photoreduction reaction kinetics compared to TiO2 nanoparticles (TiO2 NPs). This super photocatalytic performance is derived from the efficient photogenerated charge kinetics, which is steered by the conductive network and dipole field. The conductivity enhancement of the TiO2 network is achieved by continuous chemical bonds, which promotes electron–hole (e–h) separation. In addition, at the interface of Ti3C2 and TiO2, band bending induced by the dipole field promotes photogenerated electron spatially directed transfer to the catalytic sites on Ti3C2. This study demonstrates that a conductive network and dipole field offer a new concept to harness charge kinetics for photocatalysis.

Published: September 2021

AbstractThe magnetic skyrmion is a topologically protected spin texture that has attracted much attention as a promising information carrier because of its distinct features of suitability for high‐density storage, low power consumption, and stability. One of the skyrmion devices proposed so far is the skyrmion racetrack memory, which is the skyrmion version of the domain‐wall racetrack memory. For application in devices, skyrmion racetrack memory requires electrical generation, deletion, and displacement of isolated skyrmions. Despite the progress in experimental demonstrations of skyrmion generation, deletion, and displacement, these three operations have yet to be realized in one device. Here, a route for generating and deleting isolated skyrmion‐bubbles through vertical current injection with an explanation of its microscopic origin is presented. By combining the proposed skyrmion‐bubble generation/deletion method with the spin–orbit‐torque‐driven skyrmion shift, a proof‐of‐concept experimental demonstration of the skyrmion racetrack memory operation in a three‐terminal device structure is provided.

Published: September 2021

AbstractWe report an approach for the intramolecular C(sp2)−H amidation of N‐acyloxyamides under photoredox conditions to produce δ‐benzolactams with an aryl‐alkyl σ‐bond relocation. Computational studies on the designed reductive single electron transfer strategy led us to identify N‐[3,5‐bis(trifluoromethyl)benzoyl] group as the most effective amidyl radical precursor. Upon the formation of an azaspirocyclic radical intermediate by the selective ipso‐addition with outcompeting an ortho‐attack, radical–polar crossover was then rationalized to lead to the rearomative ring‐expansion with preferential C−C bond migration.

AbstractWhite‐light emitting polymers (WLEPs) based on aggregation microenvironment‐sensitive aggregation‐induced emission (AIE) and Förster resonance energy transfer (FRET) have aroused great interest in lighting and optoelectronic devices. Herein, we developed a novel strategy to construct WLEP particles via a stepwise self‐stabilized precipitation polymerization of two emission‐complementary AIEgens under core–shell engineering, where the AIE characteristics and FRET process of core–shell fluorescent polymeric particles (CS‐FPPs) could be modulated by altering aggregation microenvironment under swelling and shrinking of polymers, facilitating the tunable white light emission of CS‐FPPs. Furthermore, such tuning could be fast realized in the solid state, thus demonstrating the potential in anti‐counterfeiting. This work proved the significance of aggregation microenvironment on emission of luminogens, guiding the development of high‐efficiency emission‐tunable materials.
