Abstract. Yellowfin tuna (Thunnus albacares) is a large pelagic fish that have high economic value and inhabits the Moluccas Sea, Indonesia. Tuna catches in the Moluccas sea was very high and might decrease the yellowfin tuna population in this region. The research on population genetic of yellowfin tuna is fundamental to answer the problem. This information can be used as baseline data for future management, utilization, and basis of genetic conservation. The objective of this research was to infer the genetic population structure of two populations (North Maluku and Ambon) in the Moluccas Sea, Indonesia. In total, 41 tissue samples from pectoral fins of yellowfin tuna were collected in this study (North Maluku 33 samples and Ambon 8 samples). The results showed that genetic distances were low between the two populations. Additionally, the comparison of genetic distance between the Moluccas population and Indian Ocean waters also showed no significant differences. The Fst analysis showed the high gene flow between these two populations. Furthermore, haplotype network analysis showed that these two populations were the panmixia population. The overall result showed that no refraction genetic in the yellowfin tuna population from two populations in the Moluccas Sea.Keywords: Haplotype, genetic distance, Moluccas Sea, index fixation analysis, yellowfin tuna, population genetic structure.

Background
Despite advances in immunosuppression and surgical technique, pancreas transplantation is encumbered with a high rate of complication and graft losses. Particularly, venous graft thrombi occur relatively frequently and are rarely detected before the transplant is irreversibly damaged.

Methods
To detect complications early, when the grafts are potentially salvageable, we placed microdialysis catheters anteriorly and posteriorly to the graft in a cohort of 34 consecutive patients. Glucose, lactate, pyruvate, and glycerol were measured at the bedside every 1–2 hours.

Results
Nine patients with graft venous thrombosis had significant lactate and lactate–to-pyruvate-ratio increases without concomitant rise in blood glucose or clinical symptoms. The median lactate in these patients was significantly higher in both catheters compared to non-events (n = 15). Out of the nine thrombi, four grafts underwent successful angiographic extraction, one did not require intervention and four grafts were irreversibly damaged and explanted. Four patients with enteric anastomosis leakages had significantly higher glycerol measurements compared to non-events. As with the venous thrombi, lactate and lactate-to-pyruvate ratio were also increased in six patients with graft surrounding hematomas.

Conclusions
Bedside monitoring with microdialysis catheters is a promising surveillance modality of pancreatic grafts, but differentiating between the various pathologies proves challenging.

Published: March 2021

Background
The coronavirus infectious disease 19 (COVID-19) pandemic has resulted in significant morbidities, severe acute respiratory failures and subsequently emergency departments’ (EDs) overcrowding in a context of insufficient laboratory testing capacities. The development of decision support tools for real-time clinical diagnosis of COVID-19 is of prime importance to assist patients’ triage and allocate resources for patients at risk.

Methods and principal findings
From March 2 to June 15, 2020, clinical patterns of COVID-19 suspected patients at admission to the EDs of Liège University Hospital, consisting in the recording of eleven symptoms (i.e. dyspnoea, chest pain, rhinorrhoea, sore throat, dry cough, wet cough, diarrhoea, headache, myalgia, fever and anosmia) plus age and gender, were investigated during the first COVID-19 pandemic wave. Indeed, 573 SARS-CoV-2 cases confirmed by qRT-PCR before mid-June 2020, and 1579 suspected cases that were subsequently determined to be qRT-PCR negative for the detection of SARS-CoV-2 were enrolled in this study. Using multivariate binary logistic regression, two most relevant symptoms of COVID-19 were identified in addition of the age of the patient, i.e. fever (odds ratio [OR] = 3.66; 95% CI: 2.97–4.50), dry cough (OR = 1.71; 95% CI: 1.39–2.12), and patients older than 56.5 y (OR = 2.07; 95% CI: 1.67–2.58). Two additional symptoms (chest pain and sore throat) appeared significantly less associated to the confirmed COVID-19 cases with the same OR = 0.73 (95% CI: 0.56–0.94). An overall pondered (by OR) score (OPS) was calculated using all significant predictors. A receiver operating characteristic (ROC) curve was generated and the area under the ROC curve was 0.71 (95% CI: 0.68–0.73) rendering the use of the OPS to discriminate COVID-19 confirmed and unconfirmed patients. The main predictors were confirmed using both sensitivity analysis and classification tree analysis. Interestingly, a significant negative correlation was observed between the OPS and the cycle threshold (Ct values) of the qRT-PCR.

Conclusion and main significance
The proposed approach allows for the use of an interactive and adaptive clinical decision support tool. Using the clinical algorithm developed, a web-based user-interface was created to help nurses and clinicians from EDs with the triage of patients during the second COVID-19 wave.
Providing open-label placebos remotely—A randomized controlled trial in allergic rhinitis
Authors: Kube Tobias , Hofmann Verena E. , Glombiewski Julia A. , Kirsch Irving 
Published: March 2021

Background
Placebos can reduce physical symptoms even when provided with full honesty and disclosure. Yet, the precise mechanisms underlying the effects of “open-label placebos” (OLPs) have remained subject of debate. Furthermore, it is unclear whether OLPs are similarly effective when provided remotely, as is sometimes required e.g. in the current COVID-19 pandemic.

Methods
In a randomized-controlled trial, we examined the effects of OLP plus treatment as usual (TAU) compared to TAU alone on symptom reduction in people with allergic rhinitis (N = 54) over the course of two weeks. Due to the COVID-19 pandemic, OLP was provided remotely (i.e. sent via postal service). To investigate the potential influence of the clinical encounter on the effects of OLP, we manipulated the perception of the virtual clinical encounter, both with respect to verbal and nonverbal factors (augmented vs. limited encounter).

Results
The results of the manipulation check confirmed that the augmented clinical encounter was evaluated more positively than the limited encounter, in terms of perceived warmth of the provider. Participants from all treatment groups showed significant symptom reduction from baseline to two weeks later, but OLP had no incremental effect over TAU. Participants benefitted more from OLP when they did not take any other medication against allergic symptoms than when taking medication on demand. When controlling for baseline symptoms, a significant treatment by encounter interaction was found, pointing to greater symptom improvement in the OLP group when the encounter was augmented, whereas the control group improved more when the encounter was limited.

Discussion
The study demonstrates that providing OLP and enhancing the encounter remotely is possible, but their effectiveness might be lower in comparison to previous studies relying on physical patient-provider interaction. The study raises questions for future research about the potential and challenges of remote placebo studies and virtual clinical encounters. The study has been registered as a clinical trial at ISRCTN (record number: 39018).

AbstractBlaps rynchopeteraFairmaire has a long history of use as a folk medicine in China for treating fever, cough, gastritis, boils, and tumors. In the present study, the content analyses, monosaccharide composition analyses, and the macrophage phagocytic activity ofrynchopeterapolysaccharides (RPS) were reported.B. rhynchopterais rich in polysaccharides (content value 3.97%). Through PMP (1-phenyl-3-methyl-5-pyrazolone) pre-column derivatization and high performance liquid chromatography (HPLC) testing, the results showed that RPS consist of 8 known monosaccharides, including D-mannose (Man), Rhamnose (Rha), D-glucuronic acid (GlcUA), D-galacturonic acid (GalUA), D-glucose (Glc), D-galactose (Gal), Arabinose (Ara), and Fucose (Fuc), with the total content of 171.70 mg g−1and Glc has the highest content of 45.40 mg g−1. The phagocytic ability of mouse peritoneal macrophages was investigated after RPS stimulating alone and combined with lipopolysaccharide (LPS). RPS played an important role in the engulfment of mouse peritoneal macrophages and can significantly enhance the phagocytic ability of macrophages. However, no synergistic effects were observed when RPS combined with LPS.
Energy Contraction and Optimal Convergence of Adaptive Iterative Linearized Finite Element Methods

Abstract
We revisit a unified methodology for the iterative solution of nonlinear equations in Hilbert spaces. Our key observation is that the general approach from [P. Heid and T. P. Wihler,

satisfies an energy contraction property in the context of (abstract) strongly monotone problems. This property, in turn, is the crucial ingredient in the recent convergence analysis in [G. Gantner, A. Haberl, D. Praetorius and S. Schimanko,
Rate optimality of adaptive finite element methods with respect to the overall computational costs,

Published: March 2021

Abstract
The main purpose of this work is to study transmission dynamics of COVID-19 in Italy 2020, where the first case of Coronavirus disease 2019 (COVID-19) in Italy was reported on 31st January 2020. Taking into account the uncertainty due to the limited information about the Coronavirus (COVID-19), we have taken the modified Susceptible-Asymptomatic-Infectious-Recovered (SAIR) compartmental model under fractional order framework. We have formulated our model by subdividing infectious compartment into two sub compartments (reported and unreported) and introduced hospitalized class. In this work, we have studied the local and global stability of the system at different equilibrium points (disease free and endemic) and calculated sensitivity index for Italy scenario. The validity of the model is justified by comparing real data with the results obtained from simulations.
Teaching Linear Algebra in Engineering Courses Using Critical Thinking
Authors: Catarino Paula , Vasco Paulo 
Published: March 2021

Abstract
Nowadays it is important to improve in higher education students the critical thinking skills and dispositions in the different curricular units that are part of their schooling. Since “Linear Algebra” is a curricular unit part of any degree in engineering, we show that it is possible to integrate activities in their classes that enable the development of skills and critical thinking dispositions by students. We present examples of such activities for one item/topic of the syllabus of Linear Algebra as a proposal for future implementation in the teaching process. We will apply principles of instructional design planning and evaluation of those activities that develop critical thinking skills and dispositions in students. We will also apply active learning principles and cooperative learning strategies, including the learning based on problem solving, using questioning.
Gaps in sociolinguistic research in sub-Saharan Africa
Authors: Djité Paulin G. 
Published: March 2021

Abstract
In the mid-1960s, a catchphrase in academic circles was, « Des chercheurs qui cherchent, on en trouve; mais des chercheurs qui trouvent, on en cherche », pointing out that many researchers were “Chindōgu researchers”, that is to say researchers engaging in “useless” research, rather than coming up with actionable research findings. Along the same lines, this paper sets out to offer an analytical perspective on sociolinguistic research output and focus in sub-Saharan Africa and suggest a number of sociolinguistic research priorities.
Procesos y materialidad en el estudio del lenguaje en sociedad
Authors: Zavala Virginia 
Published: March 2021

Abstract
In this brief essay, and making use of my own research in Peru, I raise two issues that I have been reflecting on throughout my career and that I believe constitute challenges in addressing language in society. The first refers to the importance of studying the processes of meaning production from an ethnographic perspective, and the second, to the centrality of articulating the production of these meanings with the material conditions of existence that make them possible or difficult. These two points are committed to combining ethnographic sociolinguistics and glotopolitics, as critical perspectives that are enhancing sociolinguistics in Latin America.
Publishing policy: toward counterbalancing the inequalities in academia
Authors: Dołowy-Rybińska Nicole 
Published: March 2021

Abstract
This article touches upon the problem of inequalities in academia resulting from neoliberal capitalism and existing publishing policy and discusses its possible consequences. Building on the author’s own experiences as a researcher working on linguistic minorities and as an academic administrator, it explores how power relations work in parts of the scientific world situated on the peripheries of the Western “centre” – via the neoliberal economy, access to funding and international recognition. Publishing in high-status, English-language journals requires “non-centre” academics to adopt Western conventions of publishing, including in the style of reasoning, the structure of the text, and preferring references from the Anglo-American academic tradition. Only by complying can such researchers secure a place in academia and further their careers. However difficult it may be, the author argues, the hegemony of Western-model knowledge construction may only be questioned from inside, by the “centre” academics.
Whose hearing matters? Context and regimes of perception in sociolinguistics
Authors: Lo Adrienne 
Published: March 2021

Abstract
This piece argues for the importance of centering regimes of perception and the dynamics of power in sociolinguistics, drawing upon cases where Chinese and Korean terms have been heard and enregistered as English slurs. It notes how different interlocutors mobilize phenomena at various scales in invocations of context. It calls for greater attention to the range of subject positions that are produced by speakers, perceivers, and institutions and a reconsideration of the moral certainty of our analyses. It challenges us to rethink the ontological status of the linguistic sign as a self-presenting entity and to develop frameworks of analysis that can look across scales.
Chinese Film Studies Online: Technological Innovations, Pedagogical Challenges, and Teaching Chinese-Language Cinema in the Digital Age
Authors: Marchetti Gina 
Published: March 2021

Abstract
Because of the impact of the COVID-19 pandemic on higher education, online initiatives have moved from the periphery to the very heart of teaching and learning across disciplines. However, the profession has just begun to consider the full impact these new technologies have on the way we research and teach Chinese-language cinema. Using the Massive Open Online Course (MOOC) and University of Hong Kong Common Core campus-based course, Hong Kong Cinema through a Global Lens, as my principal case study, I explore some of the ways in which the digital revolution has transformed research on and teaching about Hong Kong film. From surveying the types of material available for research to exploring the differences between MOOCs and flipped classrooms, this essay considers the positive implications and potential drawbacks of these new technologies in global, regional, and local educational contexts.

Stress Testing to Assess Recovery from Extreme Events
Authors: Plodinec M. John 
Published: March 2021

Abstract
Over the last decade, communities have become increasingly aware of the risks they face. They are threatened by natural disasters, which may be exacerbated by climate change and the movement of land masses. Growing globalization has made a pandemic due to the rapid spread of highly infectious diseases ever more likely. Societal discord breeds its own threats, not the least of which is the spread of radical ideologies giving rise to terrorism. The accelerating rate of technological change has bred its own social and economic risks. This widening spectrum of risk poses a difficult question to every community – how resilient will the community be to the extreme events it faces. In this paper, we present a new approach to answering that question. It is based on the stress testing of financial institutions required by regulators in the United States and elsewhere. It generalizes stress testing by expanding the concept of “capital” beyond finance to include the other “capitals” (e.g., human, social) possessed by a community. Through use of this approach, communities can determine which investments of its capitals are most likely to improve its resilience. We provide an example of using the approach, and discuss its potential benefits.
On the Nature of Persons; Persons as Constituted Events
Authors: Tahmasbi Mohammad Reza 
Published: March 2021

Abstract
The diachronic question of persons deals with personal identity over time: “In virtue of what conditions is a person, P
1, at t
1, the same person, P
2, at t
2?” To answer the question, I suggest expanding the constitution theory from a static definition to a dynamic definition. ‘Life’ is an event and the stream of consciousness is an event too. Reflective self-consciousness—which I take to be definitive of persons—is an event. Persons are irreducible constituted events who remain the same through time while they undergo change. This idea faces neither the problem of substance dualism nor the fission problem.
