Abstract
Plasmonic nanostructures are widely utilized in surface-enhanced Raman spectroscopy (SERS) from ultraviolet to near-infrared applications. Periodic nanoplasmonic systems such as plasmonic gratings are of great interest as SERS-active substrates due to their strong polarization dependence and ease of fabrication. In this work, we modelled a silver grating that manifests a subradiant plasmonic resonance as a dip in its reflectivity with significant near-field enhancement only for transverse-magnetic (TM) polarization of light. We investigated the role of its fill factor, commonly defined as a ratio between the width of the grating groove and the grating period, on the SERS enhancement. We designed multiple gratings having different fill factors using finite-difference time-domain (FDTD) simulations to incorporate different degrees of spectral detunings in their reflection dips from our Raman excitation (488 nm). Our numerical studies suggested that by tuning the spectral position of the optical resonance of the grating, via modifying their fill factor, we could optimize the achievable SERS enhancement. Moreover, by changing the polarization of the excitation light from transverse-magnetic to transverse-electric, we can disable the optical resonance of the gratings resulting in negligible SERS performance. To verify this, we fabricated and optically characterized the modelled gratings and ensured the presence of the desired detunings in their optical responses. Our Raman analysis on riboflavin confirmed that the higher overlap between the grating resonance and the intended Raman excitation yields stronger Raman enhancement only for TM polarized light. Our findings provide insight on the development of fabrication-friendly plasmonic gratings for optimal intensification of the Raman signal with an extra degree of control through the polarization of the excitation light. This feature enables studying Raman signal of exactly the same molecules with and without electromagnetic SERS enhancements, just by changing the polarization of the excitation, and thereby permits detailed studies on the selection rules and the chemical enhancements possibly involved in SERS.
Inadvertent arterial & venous injury by bone marrow biopsy needle: case report on rescue embolization techniques
Authors: Tsai Chris Siu-Chun , Yu Simon Chun-Ho 
Published: November 2020

Abstract

Background
Bone marrow biopsy is a common medical procedure for diagnosis and characterization of haematological diseases. It is generally regarded as a safe procedure with low rate of major complications. Inadvertent vascular injury is however an uncommon but important complication of bone marrow biopsy procedure. The knowledge of a safe and effective embolization method is crucial for interventional radiologists to reduce significant patient morbidity and mortality, shall such inadvertent vascular injury occurs.

Case presentation
Bedside bone marrow biopsy was performed for an elderly gentleman to evaluate for his underlying acute leukaemia. Biopsy needle inadvertently injured the internal iliac artery and vein during the procedure. Coil embolization was carefully performed across injured arterial segment via the culprit biopsy needle until contrast cessation. Concomitant venous injury was subsequently confirmed on angiography when the needle was withdrawn for a short distance from the iliac artery. This venous injury was tackled by further withdrawing the biopsy needle to distal end of the bone marrow tract for tract embolization with coils and gelatin sponges. High caution was made to avoid coil dislodgement into the iliac vein, to prevent pulmonary embolism. Patient was clinically stable throughout the procedure. Post-procedure contrast CT shows no pelvic haematoma or contrast extravasation.

Conclusions
This case illustrates rescue embolization techniques for rare life-threatening concomitant internal iliac arterial and venous injuries by a bone marrow biopsy needle. Interventional radiologists can play an important role in carrying out precise embolization to avoid significant patient morbidity and mortality in the case of life-threatening haemorrhage.
Targeting Cancer Cells via N-degron-based PROTACs
Authors: Eldeeb Mohamed A , Zorca Cornelia E , Fahlman Richard P 
Published: November 2020

Abstract
In mammals, protein degradation is mediated selectively by the ubiquitin proteasome system (UPS) and the autophagic-lysosomal system. Over the past decades, N-degron pathways have been shown to be responsible for the selective degradation of proteins that harbor destabilizing N-terminal motifs. Recent studies have employed these pathways in the development of proteolysis targeting chimeras (PROTACs) composed of a degradation module linked to a substrate recognition domain to target proteins encoded by cancer-related genes for proteasomal destruction. Herein we provide an overview of PROTACs in the context of the N-degron concept and address the application of this technique to curb the migration and invasion of cancer cells, with a focus on the far-reaching potential of exploiting N-degron pathways for therapeutic purposes.
Change: Viktor&Rolf Haute Couture, Autumn/Winter 2020
Authors: Smith Lorraine Hamilton 
Published: November 2020

Abstract
Lockdown restrictions that were put in place by governments across the world during the first half of 2020 had a huge impact on the fashion industry, the full effects of which will perhaps be felt for years to come. In this short article, I will analyse the Viktor&Rolf Haute Couture, Autumn/Winter 2020 collection, which was created during this time and which directly references the change in mindset that designers and consumers alike have experienced; I will consider how the online-only presentation method has been used to further enhance the message conveyed by the clothing. The setting, music and voice-over used in this short fashion film are seemingly intended to bring an overall feeling of hope, and possibly joy, to the display of a small, yet cohesive collection that addresses the complex feelings of anxiety and isolation that characterize this historical moment.
“Workers + Warriors”

Published: November 2020

For this special issue, we bring together an array of interdisciplinary international scholars who are working across the fields of Black studies, African diasporic studies, slavery studies, American studies, and memory studies. They debate, destabilize, interrogate, and reshape widely known and accepted methodologies within literary studies, art history, visual culture, history, intellectual history, politics, sociology, and material and print cultures in order to do justice to the hidden histories, untold narratives, and buried memories of African diasporic freedom struggles over the centuries. This collection is the result of a symposium that we held in Edinburgh, Scotland, in 2018 as part of a UK Arts and Humanities Research Council project titled Our Bondage and Our Freedom: Struggles for Liberty in the Lives and Works of Frederick Douglass and His Family (1818–1920). The inspiration for this project, which we launched in 2018 on the two-hundredth anniversary of Frederick Douglass’s birth, emerged from a determination to revisit his legendary life and pioneering works. A world-renowned freedom fighter, inspirational social justice campaigner, mythologized liberator, exemplary philosopher, breathtaking orator, and beautiful writer, Douglass dedicated his life to the fight for Black liberation by any and every means necessary. As he repeatedly maintained in the motto he endorsed for his radical newspaper, the North Star, “Right is of no sex—Truth is of no color—God is the Father of us all, and we are brethren.”
Through engaging with the narratives, poetry, speeches, songs, oral testimonies, correspondence, essays, photography, drawings, paintings, and sculptures produced by and/or representing Douglass and his family members, it becomes newly possible to do justice to the psychological, imaginative, and emotional realities of iconic and unknown Black lives as lived during slavery and into the post-emancipation era. Two hundred years after Douglass’s birth, in the era of Black Lives Matter, there can be no doubt that the Douglass we need now is no representative self-made man but a fallible, mortal individual. The onus is on academics, archivists, artists, and activists to harness every intellectual tool available in order to tell the stories not only of Black women, children, and men living in slavery but of Black women, children, and men experiencing the illusory freedoms of the post-emancipation era. For Douglass’s rallying cry “My Bondage and My Freedom” it is possible to read “Our Bondage and Our Freedom.
Frederick Douglass
Authors: Geoff Palmer  
Published: November 2020

Frederick Douglass, Black abolitionist, author, and statesman, was born into chattel slavery in the United States in 1818. Douglass’s antislavery activism inspired his sons to fight in the Civil War to end slavery in the nation (1861–1865). It also enabled him to meet other U.S. abolitionists such as James McCune Smith, the first Black American graduate in medicine (Glasgow University, 1837), as well as John Brown and Abraham Lincoln. Douglass arrived in Scotland in 1846, where he gave many lectures on the evils of chattel slavery and was aware of the roles politicians and the church played in maintaining this institution. He argued that if the Free Church of Scotland refused to help to abolish slavery in the United States, it should “Send Back The Money” that it acquired from slaveholding investors. A commemorative plaque to Frederick Douglass was unveiled in Edinburgh in November 2018. This article reflects on Frederick Douglass’s activism in Scotland and what it means for Scotland’s African diasporic residents.
The Fugitivity of Art
Authors: Diane C. Fujino  
Published: November 2020

This article examines the art practices of Akinsanya Kambon, Pan-African artist, activist, and former Black Panther. Fujino posits that Kambon’s art and activism embody a marronage politic through the creation of alternative spaces that reject the logics of racial capitalism and white assimilationism. Whether as a fugitive living in clandestinity or as co-owner of a Pan-African art studio and gallery, Kambon—through his sculptures, paintings, drawings, and accompanying griot storytelling—has emphasized African creation of art, knowledge reclaimed from the ancestors, revolutionary theories and practices, and emancipatory imaginations. The Black Atlantic figures prominently in his art and ideology.
Project “Schule für alle” as a mentoring programme in university teacher education: Professionalization processes of student teachers in different practical university phases
Authors: Kottmann Brigitte , Pieper Catania 
Published: November 2020

AbstractIn the mentoring programme project “Schule für alle” (“School for all”) at the University of Bielefeld in North Rhine-Westphalia, university students of primary or special education support a child who is in a situation of crisis for more than one year. In addition, the university students receive ongoing, systematic university support (cf. Kottmann, 2007, p. 32; Kottmann, 2014, p. 380).The accompanying research by “Schule für alle” focuses on the professionalization processes of student teachers during practical phases at universities; accordingly, control groups were included on a pro rata basis. In the pre-post design, all students completed a questionnaire (cf. Pieper, Kottmann & Miller, 2018, p. 294), the evaluation of which shows few changes in the professional perception of competence. Students of the mentoring programme also regularly reflected on their practical experience. Based on the objective hermeneutics it was discovered that the conception of the project supports the process of perceiving, acknowledging and becoming more sensitive in regard to heterogeneous realities in life (cf. Pieper & Kottmann 2019b, p. 312) and that students can consciously perceive and reflect their own normative expectations (cf. Pieper & Kottmann 2019a, p. 79).The article primarily presents the results of the pre-post survey in detail and adds insights into the qualitative evaluation processes. In the conclusion, the potential of the project and mentoring programmes in general, specifically for teacher training students, is described.
Vitamin E as promising adjunct treatment option in the combat of infectious diseases caused by bacterial including multi-drug resistant pathogens – Results from a comprehensive literature survey
Authors: Hartmann Minnja S. , Mousavi Soraya , Bereswill Stefan , Heimesaat Markus M. 
Published: November 2020

AbstractThe use of antibiotics has provoked an emergence of various multidrug-resistant (MDR) bacteria. Infectious diseases that cannot be treated sufficiently with conventional antibiotic intervention strategies anymore constitue serious threats to human health. Therefore, current research focus has shifted to alternative, antibiotic-independent therapeutic approaches. In this context, vitamin E constitutes a promising candidate molecule due to its multi-faceted modes of action. Therefore, we used the PubMed database to perform a comprehensive literature survey reviewing studies addressing the antimicrobial properties of vitamin E against bacterial pathogens including MDR bacteria. The included studies published between 2010 and 2020 revealed that given its potent synergistic antimicrobial effects in combination with distinct antibiotic compounds, vitamin E constitutes a promising adjunct antibiotic treatment option directed against infectious diseases caused by MDR bacteria such asPseudomonas aeruginosa,Burkholderia cenocepaciaand methicillin-resistantStaphylococcus aureus(MRSA). In conclusion, the therapeutic value of vitamin E for the treatment of bacterial infections should therefore be investigated in future clinical studies.
Mobile and non-mobile Internet Use Disorder: Specific risks and possible shared Pavlovian conditioning processes. •
Authors: Moretta Tania , Chen Shubao , Potenza Marc N. 
Published: November 2020

AbstractThis commentary addresses a recent article by Montag et al. (2019) about the relevance of distinguishing between mobile and non-mobile Internet Use Disorder (IUD). In response to the review, we reflect on the clinical relevance of this distinction and, in parallel, we propose some Pavlovian conditioning processes as possible mechanisms underlying different IUDs. We believe that, from a clinical point of view, it is of fundamental importance assessing both specific “forms” of IUDs and the underlying mechanisms that would be shared across different IUDs, like multiple and parallel classes of Pavlovian responses and the influences of Internet cues on Internet-related addictive behaviors that may be influenced by the probability of obtaining Internet rewards.
Risk reduction and harm prevention in technology use. •
Authors: Kuss Daria J. 
Published: November 2020

AbstractThis commentary paper draws on Swanton et al.'s (2020) paper “Problematic risk-taking involving emerging technologies: A stakeholder framework to minimize harms” to discuss issues pertaining to the challenges and possible risks emerging technologies may pose for the users. It acknowledges technology use is not problematic per se, but for some users, it can be associated with preventable harms. Corporate social responsibility is called for to protect consumers. It is argued that there exists a collective responsibility to ensure technology can be used in a healthy and beneficial way, risk is reduced and harm is prevented.
Identification of base erosion and profit shifting using tax evasion rate
Authors: Friedrich Michal , Tepperova Jana 
Published: November 2020

AbstractMultinational enterprises (MNEs) use different methods and structures for base erosion and profit shifting (BEPS) to optimize the tax liability of the group. It is of great interest to the relevant countries to be able to identify such practices and react with appropriate measures. The objective of this paper is to verify whether selected MNEs engaged in the digital economy tend to shift profits from the Czech Republic to jurisdictions with lower taxation using the tax evasion rate (TER) indicator and the transactional net margin method (TNNM). Since the TER method has not been tested yet, this paper also aims to demonstrate its application on real world data and to evaluate its usability. On a sample of five MNEs, the analysis showed a potential tendency to shift profits within Europe for four MNEs (Amazon, Apple, Google and Uber) and a potential tendency to shift profits specifically from the Czech Republic for one MNE (Amazon). The analysis shows that TER is suitable as a preliminary indication of possible risks, rather than their exact quantification.

Published: November 2020

El presente artículo establece una visión especial de la problemática fiscal de las finanzas territoriales en el Distrito Barranquilla, durante la vigencia del año 2015 al 2017; ya que en la actualidad existen factores que limitan la autonomía administrativa y presupuestal de las entidades territoriales del país, como es el déficit económico actual como resultado de una política fiscal que cada día se torna más insostenible y qué es en gran parte debido al manejo indebido de las finanzas públicas territoriales, al no distribuir de forma correcta los recursos disponibles se genera una deuda con acreedores y entidades financieras. Uno de los factores que más incide es la falta de “Cultura Tributaria”, situación relevante que ha sido tomada como justificación a la promulgación de diversas y constantes reformas tributarias que han generado regulaciones aisladas en materia tributaria

POLÍTICA SOCIAL DE EMPLEO Y DESEMPLEO, COMO UN RETO JURÍDICO NORMATIVO EN COLOMBIA
Authors: PÉREZ VANEGAS Lenin Esteban 
Published: November 2020

A partir del año de 1990, con la entrada rampante del neoliberalismo a Colombia, el país entro en un desequilibrio estructural de las finanzas públicas, en tal forma que tuvo que realizar esfuerzos económicos muy grandes para poder instaurar y consolidar el modelo de globalización neoliberal impuestos al mundo por las elites imperialistas de Norte América y Europa; para el cual el país no estaba preparado económicamente.Para mitigar la crisis del capitalismo, se recurrió a incrementar impuestos, a privatizar el patrimonio público, los servicios la infraestructura, y hasta los derechos fundamentales, a recortar costos laborales, y a crear exenciones y deducciones para estimular la inversión externa, lo cual llevo al país a una crisis sistemática de las finanzas públicas.1Para la mejor comprensión del tema, se ilustrarán las políticas públicas, sociales y políticas teniendo como finalidad tratar de dilucidar, como la flexibilización laboral es un retroceso en materia de garantías y derechos sociales, en la búsqueda generar un ambiente de confianza inversionista para los capitales y monopolios extranjeros, adecuando la economía colombiana a tono con las condiciones de la globalización e implementando políticas económicas, cambiarias monetarias y fiscales que le dan prioridad a las necesidades actuales del capital financiero.Así pues se tomará como referente teórico la posición del Doctor Aurelio Suarez Montoya, acerca del desarrollo de la economía Colombiana, expuesta en su libro Confianza Inversionista, quien manifiesta que el único capaz de brindar empleos dignos, bien remunerados y con todas las garantías constitucionales entendidas dentro del bloque de constitucionalidad, es el Estado colombiano, sin dejar de reconocer el papel fundamental que juega el sector privado dentro de economía; pero resaltando de igual forma al servicio de quien debe estar encaminada la institucionalidad, y a donde se deben dirigir las políticas económicas y sociales; y de igual forma los planteamientos del Doctor Carlos Gaviria Díaz, en materia de Estado Social de Derecho, desarrollados en su compilación jurisprudencial a lo largo de su carrera como magistrado de Corte Constitucional Colombiana.Por otro lado se acudirá como referentes históricos y políticos los postulados de Francisco Mosquera Sánchez, y Héctor Valencia Henao, los cuales realizan una radiografía de la situación política nacional e internacional y sus implicaciones en la economía Colombiana, en sus libros Resistencia Civil, y Desde la Izquierda respectivamente.
