Legal Interventions and Transnational Alliances in the Ali Enterprises Case: Struggles for Workers’ Rights in Global Supply Chains
Authors: Saage-Maaß Miriam 
Published: June 2021

AbstractThis article highlights the persistence of exploitative working conditions in global supply chains resulting from the constant need to externalise costs and increase consumption with a view to sustaining the “imperial lifestyle” of people in the Global North. While the law structures today’s global value chains and is designed to secure the economic interests of Global North companies that sit at the top of most of such chains, it also bears considerable potential for transformation and empowerment. The different legal interventions around the 2012 Ali Enterprises factory fire demonstrate that law is not only a direct product of dominant class interests, but that it can also open up opportunities for resistance and emancipatory struggle. Written from the perspective of one of the actors closely involved in the legal struggle for justice that followed the Ali Enterprises factory fire, both in terms of building transnational alliances as well as in the litigation itself, this chapter critically reflects on the achievements of the legal interventions carried out and also attempts to develop criteria for a holistic approach to what is often called strategic litigation.
The Rana Plaza Collapse and the Case for Enforceable Agreements with Apparel Brands
Authors: Vanpeperstraete Ben 
Published: June 2021

AbstractDisasters like the Rana Plaza collapse and the Tazreen Fashions and Ali Enterprises fires painfully demonstrate the limits of conventional models of labour regulation in global supply chains. Buyer-driven markets characterised by outsourcing, subcontracting and offshoring, and the price pressure that results from them, undermines both the regulatory role of the state and the potential for collective bargaining. As a result, poor and unsafe working conditions prevail in transnational corporate supply chains in the garment industry. The aforementioned disasters offer a textbook example of the challenges facing the current clothing industry and the limits of the dominant “Corporate Social Responsibility” (CSR) model used to address labour rights abuses.Yet, the responses to these disasters also provide fertile ground for alternative “worker-driven” strategies, where worker organisations enter into negotiated supply chain agreements with transnational corporations and hold the latter to account. The Bangladesh Accord and Rana Plaza Arrangement, as well as the corollary Tazreen Compensation Agreement and Ali Enterprises Compensation Agreement attempt to develop a counter-hegemonic alternative to dominant CSR practices and offer new strategies for social justice within global supply chains. This chapter describes and contextualises these agreements in a broader trajectory of labour organisations bargaining and negotiating such agreements with lead firms, highlighting how the post-Rana Plaza momentum made significant strides possible in terms of the depth, scope and enforceability of these negotiated agreements. The chapter identifies the strengths of these developments, but also identifies room for improvement for future negotiated enforceable agreements with apparel brands.
Skizzen und Fragmente für eine dekoloniale politische Bildung
Authors: Kleinschmidt Malte 
Published: June 2021

ZusammenfaasungDer hier vorliegende Text zielt darauf ab, Impulse für die Konzeption einer dekolonial ausgerichteten politischen Bildung zu entwickeln, die aus meiner Perspektive als eigenständiges Feld notwendig erscheint und als fundamentaler Bestandteil einer sich als kritisch verstehenden politischen Bildung (Lösch/Thimmel 2010) anerkannt werden sollte. Gleichzeitig kann sie auch als eine Dekolonisierung der gegenwärtig hegemonialen politischen Bildung gelesen werden. Um die Implikationen meiner empirischen Ergebnisse für die politische Bildung zu kontextualisieren, beziehe ich mich im gesamten Kapitel auf bestehende Ansätze dekolonialer – wenngleich natürlich hochpolitisch, nicht explizit der Fachdisziplin der Didaktik der politischen Bildung zugeordneten – Bildungsperspektiven, im deutschsprachigen Raum vertreten beispielsweise durch María do Mar Castro Varela oder Patricia Baquero Torres.
The structure of IR divergences in celestial gluon amplitudes
Authors: González Hernán A. , Rojas Francisco 
Published: June 2021

Abstract
The all-loop resummation of SU(N) gauge theory amplitudes is known to factorize into an IR-divergent (soft and collinear) factor and a finite (hard) piece. The divergent factor is universal, whereas the hard function is a process-dependent quantity.We prove that this factorization persists for the corresponding celestial amplitudes. Moreover, the soft/collinear factor becomes a scalar correlator of the product of renormalized Wilson lines defined in terms of celestial data. Their effect on the hard amplitude is a shift in the scaling dimensions by an infinite amount, proportional to the cusp anomalous dimension. This leads us to conclude that the celestial-IR-safe gluon amplitude corresponds to a expectation value of operators dressed with Wilson line primaries. These results hold for finite N.In the large N limit, we show that the soft/collinear correlator can be described in terms of vertex operators in a Coulomb gas of colored scalar primaries with nearest neighbor interactions. In the particular cases of four and five gluons in planar $$ \mathcal{N} $$
N
= 4 SYM theory, where the hard factor is known to exponentiate, we establish that the Mellin transform converges in the UV thanks to the fact that the cusp anomalous dimension is a positive quantity. In other words, the very existence of the full celestial amplitude is owed to the positivity of the cusp anomalous dimension.
Electroweak axion string and superconductivity
Authors: Abe Yoshihiko , Hamada Yu , Yoshioka Koichi 
Published: June 2021

Abstract
We study the axion strings with the electroweak gauge flux in the DFSZ axion model and show that these strings, called the electroweak axion strings, can exhibit superconductivity without fermionic zeromodes. We construct three types of electroweak axion string solutions. Among them, the string with W-flux can be lightest in some parameter space, which leads to a stable superconducting cosmic string. We also show that a large electric current can flow along the string due to the Peccei-Quinn scale much higher than the electroweak scale. This large current induces a net attractive force between the axion strings with the same topological charge, which opens a novel possibility that the axion strings form Y-junctions in the early universe.
The forgotten channels: charged Higgs boson decays to a W± and a non-SM-like Higgs boson
Authors: Bahl Henning , Stefaniak Tim , Wittbrodt Jonas 
Published: June 2021

Abstract
The presence of charged Higgs bosons is a generic prediction of multiplet extensions of the Standard Model (SM) Higgs sector. Focusing on the Two-Higgs-Doublet-Model (2HDM) with type I and lepton-specific Yukawa sectors, we discuss the charged Higgs boson collider phenomenology in the theoretically and experimentally viable parameter space. While almost all existing experimental searches at the LHC target the fermionic decays of charged Higgs bosons, we point out that the bosonic decay channels — especially the decay into a non-SM-like Higgs boson and a W boson — often dominate over the fermionic channels. Moreover, we revisit two genuine BSM effects on the properties of the discovered Higgs boson — the charged Higgs contribution to the diphoton rate and the Higgs decay to two light Higgs bosons — and their implication for the charged Higgs boson phenomenology. As main result of the present paper, we propose five two-dimensional benchmark scenarios with distinct phenomenological features in order to facilitate the design of dedicated LHC searches for charged Higgs bosons decaying into a W boson and a light, non-SM-like Higgs boson.
Complement as driver of systemic inflammation and organ failure in trauma, burn, and sepsis
Authors: Mannes Marco , Schmidt Christoph Q. , Nilsson Bo , Ekdahl Kristina N. , Huber-Lang Markus 
Published: June 2021

AbstractComplement is one of the most ancient defense systems. It gets strongly activated immediately after acute injuries like trauma, burn, or sepsis and helps to initiate regeneration. However, uncontrolled complement activation contributes to disease progression instead of supporting healing. Such effects are perceptible not only at the site of injury but also systemically, leading to systemic activation of other intravascular cascade systems eventually causing dysfunction of several vital organs. Understanding the complement pathomechanism and its interplay with other systems is a strict requirement for exploring novel therapeutic intervention routes. Ex vivo models exploring the cross-talk with other systems are rather limited, which complicates the determination of the exact pathophysiological roles that complement has in trauma, burn, and sepsis. Literature reporting on these three conditions is often controversial regarding the importance, distribution, and temporal occurrence of complement activation products further hampering the deduction of defined pathophysiological pathways driven by complement. Nevertheless, many in vitro experiments and animal models have shown beneficial effects of complement inhibition at different levels of the cascade. In the future, not only inhibition but also a complement reconstitution therapy should be considered in prospective studies to expedite how meaningful complement-targeted interventions need to be tailored to prevent complement augmented multi-organ failure after trauma, burn, and sepsis.This review summarizes clinically relevant studies investigating the role of complement in the acute diseases trauma, burn, and sepsis with important implications for clinical translation.
Cause of Extreme Heavy and Persistent Rainfall over Yangtze River in Summer 2020
Authors: Pan Xiao , Li Tim , Sun Ying , Zhu Zhiwei 
Published: June 2021

AbstractRecord-breaking heavy and persistent precipitation occurred over the Yangtze River Valley (YRV) in June-July (JJ) 2020. An observational data analysis has indicated that the strong and persistent rainfall arose from the confluence of southerly wind anomalies to the south associated with an extremely strong anomalous anticyclone over the western North Pacific (WNPAC) and northeasterly anomalies to the north associated with a high-pressure anomaly over Northeast Asia. A further observational and modeling study has shown that the extremely strong WNPAC was caused by both La Niña-like SST anomaly (SSTA) forcing in the equatorial Pacific and warm SSTA forcing in the tropical Indian Ocean (IO). Different from conventional central Pacific (CP) El Niños that decay slowly, a CP El Niño in early 2020 decayed quickly and became a La Niña by early summer. This quick transition had a critical impact on the WNPAC. Meanwhile, an unusually large area of SST warming occurred in the tropical IO because a moderate interannual SSTA over the IO associated with the CP El Niño was superposed by an interdecadal/long-term trend component. Numerical sensitivity experiments have demonstrated that both the heating anomaly in the IO and the heating anomaly in the tropical Pacific contributed to the formation and maintenance of the WNPAC. The persistent high-pressure anomaly in Northeast Asia was part of a stationary Rossby wave train in the midlatitudes, driven by combined heating anomalies over India, the tropical eastern Pacific, and the tropical Atlantic.
The pro-export effect of subnational migration networks: new evidence from Spanish provinces
Authors: D’Ambrosio Anna , Montresor Sandro 
Published: June 2021

AbstractThe paper investigates the effect that subnational networks of immigrants and emigrants had on exports from Spanish provinces (NUTS3) over the period of 2007–2016 by integrating state-of-the-art advances in the gravity model literature. In particular, it allows for heterogeneity in provincial export capacity, which significantly reduces pro-export effects, and select the Poisson Pseudo-Maximum Likelihood as the most suitable estimator according to diagnostic tests. When both immigration and emigration are instrumented, the pro-export effect of immigrants found by previous studies vanishes and that of emigrants, instead, appears appreciable. The results obtained suggest that over the period that encompasses the double-deep crisis, immigrants did not show significant information and enforcement effects in the considered context, while the effects of emigrant demand for home-country goods may have been important. The prevalence of emigrant over immigrant effects appears attributable to a change in the composition of the migration stocks over the considered period of crisis.
Die Regulierung der Einführung invasiver gebietsfremder Arten durch Biofouling an der Schnittstelle
zwischen Naturschutzrecht und Seeschifffahrtsrecht
Authors: Schatz Valentin J. 
Published: June 2021

ZusammenfassungBewuchs an Seeschiffen (sog. Biofouling) ist ein bedeutender Vektor bei der Einführung invasiver
gebietsfremder aquatischer Arten und damit eine Herausforderung für den Naturschutz. Da es sich hierbei
– wie beim bereits speziell regulierten Ballastwasser – um ein systemisches Problem der Seeschifffahrt
handelt, bedarf es eines speziellen Regelungssystems an der Schnittstelle zwischen Naturschutzrecht (BNatSchG)
und Seeschifffahrtsrecht (SeeAufgG und SeeUmwVerhV). Vor diesem Hintergrund untersucht dieser Beitrag die
rechtliche Regulierung von Biofouling Management. Er geht zunächst auf den völkerrechtlichen
Rahmen und die Guidelines der Internationalen Seeschifffahrtsorganisation (IMO) ein. Danach wendet sich
der Beitrag den einschlägigen Instrumenten des Unionsrechts zu. Zuletzt untersucht er das nationale
Recht, wobei im Lichte der bisherigen Regulierung in Neuseeland, Kalifornien und Australien auf künftige
gesetzgeberische Optionen in Deutschland eingegangen wird.
Continuous window functions for NFFT
Authors: Potts Daniel , Tasche Manfred 
Published: June 2021

AbstractIn this paper, we study the error behavior of the nonequispaced fast Fourier transform (NFFT). This approximate algorithm is mainly based on the convenient choice of a compactly supported window function. Here, we consider the continuous Kaiser–Bessel, continuous exp-type, sinh-type, and continuous cosh-type window functions with the same support and same shape parameter. We present novel explicit error estimates for NFFT with such a window function and derive rules for the optimal choice of the parameters involved in NFFT. The error constant of a window function depends mainly on the oversampling factor and the truncation parameter. For the considered continuous window functions, the error constants have an exponential decay with respect to the truncation parameter.

AbstractWe evaluated the impact of the coronavirus disease (COVID-19) on the sex work industry and assessed how it has impacted the health and social conditions of sex workers in Singapore. We conducted a sequential exploratory mixed methods study amidst the COVID-19 pandemic from April to October 2020, including in-depth interviews with 24 stakeholders from the sex work industry and surveyor-administered structured surveys with 171 sex workers. COVID-19 had a substantial impact on sex workers' income. The illegality of sex work, stigma, and the lack of work documentation were cited as exclusionary factors for access to alternative jobs or government relief. Sex workers had experienced an increase in food insecurity (57.3%), housing insecurity (32.8%), and sexual compromise (8.2%), as well as a decrease in access to medical services (16.4%). Being transgender female was positively associated with increased food insecurity (aPR = 1.23, 95% CI [1.08, 1.41]), housing insecurity (aPR = 1.28, 95% CI [1.03, 1.60]), and decreased access to medical services (aPR = 1.74, 95% CI [1.23, 2.46]); being a venue-based sex worker was positively associated with increased food insecurity (aPR = 1.46, 95% CI [1.00, 2.13]), and being a non-Singaporean citizen or permanent resident was positively associated with increased housing insecurity (aPR = 2.59, 95% CI [1.73, 3.85]). Our findings suggest that COVID-19 has led to a loss of income for sex workers, greater food and housing insecurity, increased sexual compromise, and reduced access to medical services for sex workers. A lack of access to government relief among sex workers exacerbated such conditions. Efforts to address such population health inequities should be implemented.
The Cognitive-Affective-Social Theory of Learning in digital Environments (CASTLE)

Published: June 2021

AbstractFor a long time, research on individuals learning in digital environments was primarily based on cognitive-oriented theories. This paper aims at providing evidence that social processes affect individual learning with digital materials. Based on these theories and empirical results, a social-processes-augmented theory is suggested: the Cognitive-Affective-Social Theory of Learning in digital Environments (CASTLE). This CASTLE postulates that social cues in digital materials activate social schemata in learners leading to enhanced (para-)social, motivational, emotional, and metacognitive processes. To substantiate this theory, socio-cognitive theories are used, which predict social influences on learning with digital materials. Besides, previous empirical findings are presented assuming that with a rising number of social cues in digital materials, the influence of social processes increases. Finally, consequences regarding the design of digital learning media are discussed.

Published: June 2021

AbstractLimited information is available on carcinogenicity of asbestos on non-respiratory organs. We aimed at conducted an updated systematic review and meta-analysis of cohort studies on occupational exposure to asbestos and risk of kidney cancer. We searched through three databases, PubMed, Embase and Scopus for article published after 2000, and after eliminating duplicates and non-relevant studies, we identified 13 studies. We combined their results with those of 31 non-overlapping studies included in a previous review up to 2000. We conducted a meta-analysis based on random-effects models. The pooled relative risk of kidney cancer for asbestos exposure was 0.94 (95% confidence interval, 0.84–1.04), with no differences according to type of asbestos fiber, geographic region, period of exposure, or estimated quality of the study. Our results showed a lack of association between occupational asbestos exposure and risk of kidney cancer.
How can we know a self-driving car is safe?
Authors: Stilgoe Jack 
Published: June 2021

AbstractSelf-driving cars promise solutions to some of the hazards of human driving but there are important questions about the safety of these new technologies. This paper takes a qualitative social science approach to the question ‘how safe is safe enough?’ Drawing on 50 interviews with people developing and researching self-driving cars, I describe two dominant narratives of safety. The first, safety-in-numbers, sees safety as a self-evident property of the technology and offers metrics in an attempt to reassure the public. The second approach, safety-by-design, starts with the challenge of safety assurance and sees the technology as intrinsically problematic. The first approach is concerned only with performance—what a self-driving system does. The second is also concerned with why systems do what they do and how they should be tested. Using insights from workshops with members of the public, I introduce a further concern that will define trustworthy self-driving cars: the intended and perceived purposes of a system. Engineers’ safety assurances will have their credibility tested in public. ‘How safe is safe enough?’ prompts further questions: ‘safe enough for what?’ and ‘safe enough for whom?’

Published: June 2021

AbstractSN38 is the active metabolite of irinotecan with 1000-fold greater cytotoxicity compared to the parent drug. Despite the potential, its application as a drug is still seriously limited due to its stability concerns and low solubility in acceptable pharmaceutical solvents. To address these drawbacks here nanostructured lipid carrier (NLC) containing SN38 was prepared and its cytotoxicity against U87MG glioblastoma cell line was investigated. The formulations were prepared using hot ultrasonication and solvent evaporation/emulsification methods. NLCs with a mean size of 140 nm and particle size distribution (PDI) of 0.25 were obtained. The average loading efficiency was 9.5% and its entrapment efficiency was 81%. In order to obtain an accurate determination of released amount of SN38 a novel medium and extraction method was designed, which lead to an appropriate in vitro release profile of the drug from the prepared NLCs. The MTT test results revealed the significant higher cytotoxicity of NLCs on U87MG human glioblastoma cell line compared with the free drug. The confocal microscopy images confirmed the proper penetration of the nanostructures into the cells within the first 4 h. Consequently, the results indicated promising potentials of the prepared NLCs as a novel treatment for glioblastoma.

AbstractChronic venous ulcers (CVU) of the lower limbs (LL) are common and cause psychological changes and significant social impact, as they make the patient susceptible to pain, absence from work and social bonds. Some materials are suggested as dressings for the treatment of CVU, but they are expensive and are generally not available for use in public health services. To evaluate the efficacy of the treatment for lower limbs (LL) chronic venous ulcer (CVU) using bacterial cellulose (BC), gel and multi-perforated film associated. A randomized controlled clinical-intervention study was performed among participants with LL CVU, divided into two groups: experimental (EG), treated with BC wound dressing and control (CG), treated with a cellulose acetate mesh impregnated with essential fatty acids (Rayon®). The participants were followed for 180 days, evaluated according to the MEASURE methodology. Thirty-nine patients were treated, 20 from the EG and 19 from the CG. In both groups, the wound area decreased significantly (p < 0.001), the healing rate was similar to the CG. The mean number of dressing changes in the SG was 18.33 ± 11.78, while in the CG it was 55.24 ± 25.81, p < 0.001. The healing dressing of bacterial cellulose, gel and associated film, when stimulating the epithelization of the lesions, showed a significant reduction in the initial area, with a percentage of cure similar to the Rayon® coverage. In addition to requiring less direct manipulation of ulcers.
