A New Application-Aware No-Reference Quality Assessment Method for IP Voice Services
Authors: Orosz Péter , Tóthfalusi Tamás 
Published: March 2021

AbstractThe increasing number of Voice over LTE deployments and IP-based voice services raise the demand for their user-centric service quality monitoring. This domain’s leading challenge is measuring user experience quality reliably without performing subjective assessments or applying the standard full-reference objective models. While the former is time- and resource-consuming and primarily executed ad-hoc, the latter depends upon a reference source and processes the voice payload that may offend user privacy. This paper presents a packet-level measurement method (introducing a novel metric set) to objectively assess network and service quality online. It is accomplished without inspecting the voice payload and needing the reference voice sample. The proposal has three contributions: (i) our method focuses on the timeliness of the media traffic. It introduces new performance metrics that describe and measure the service’s time-domain behavior from the voice application viewpoint. (ii) Based on the proposed metrics, we also present a no-reference Quality of Experience (QoE) estimation model. (iii) Additionally, we propose a new method to identify the pace of the speech (slow or dynamic) as long as voice activity detection (VAD) is present between the endpoints. This identification supports the introduced quality model to estimate the perceived quality with higher accuracy. The performance of the proposed model is validated against a full-reference voice quality estimation model called AQuA, using real VoIP traffic (originated in assorted voice samples) in controlled transmission scenarios.
Commons and the nature of modernity: towards a cosmopolitical view on craft guilds
Authors: De Munck Bert 
Published: March 2021

AbstractThis paper argues that historical research on late medieval and early modern craft guilds fails to escape teleological and anachronistic views, including when they are addressed as commons or ‘institutions for collective action’. These present-day conceptual lenses do not only create idealized views on guilds, but also of the contexts in which they operated, especially the state and the market. This is especially the case with neo-institutional views on the commons, which fall back on a transhistorical rational actor, who can choose between three options for the allocation of resources and surpluses, namely the state, the market and the common. The paper shows that guilds were fundamentally entangled with both the state and the market and that their ethic implied a less utilitarian and instrumental attitude towards natural resources. The consequence of this is that the history of the guilds offers different lessons to present-day commoners than those implied by present-day research. With an eye at launching a reflection on that, I argue in favour of a cosmopolitical perspective, which invites to take fundamentally different worldviews seriously. This includes questioning our own conceptual and analytical abstractions like the state, the market and the individual, up to and including the very distinction between nature and society or nature and politics, which are at the very basis of modern science itself.

Published: March 2021

Zusammenfassung
Hintergrund
Personale Ressourcen in Form motivationaler Faktoren haben in der bisherigen Forschung zum Thema Burnout im Hochschulkontext wenig Beachtung gefunden. Das Ziel der vorliegenden Studie war es, Annäherungslern- und -leistungsziele als personale Ressource in das etablierte Study Demands-Resources-Modell (SD-R-Modell) zu integrieren und ihren Zusammenhang mit Burnout sowie Engagement im Studium zu untersuchen.

Methodik
Mithilfe eines quantitativen Online-Fragebogens wurden Querschnittsdaten von 347 Studierenden (MAlter = 22,9, SD = 3,2 Jahre) verschiedener deutscher Hochschulen erhoben und mittels latenter Strukturgleichungsmodelle untersucht.

Ergebnisse
Die Ergebnisse zeigen, dass sich das SD-R-Modell replizieren lässt. Annäherungslernziele vermitteln den Zusammenhang zwischen Ressourcen und Engagement positiv. Entgegen der Hypothese vermitteln Annäherungslernziele den Zusammenhang zwischen Ressourcen und Burnout positiv. Leistungszielorientierung ist kein signifikanter Mediator.

Diskussion
Die Ergebnisse unterstreichen die Relevanz von Annäherungslernzielen für das Engagement und die psychische Gesundheit Studierender.
Teaching and learning robotic surgery at the dual console: a video-based qualitative analysis
Authors: Cristofari Hélène , Jung Minoa Karin , Niclauss Nadja , Toso Christian , Kloetzer Laure 
Published: March 2021

AbstractRobotic-assisted surgery (RAS) involves training processes and challenges that differ from open or laparoscopic surgery, particularly regarding the possibilities of observation and embodied guidance. The video recording and the dual-console system creates a potential opportunity for participation. Our research, conducted within the department of visceral surgery of a big Swiss, public, academic hospital, uses a methodology based on the co-analysis of video recordings with surgeons in self-confrontation interviews, to investigate the teaching activity of the lead surgeon supervising a surgeon in training at the dual console. Three short sequences have been selected for the paper. Our analysis highlights the skills-in-construction of the surgeon in training regarding communication with the operating team, fluency of working with three hands, and awareness of the whole operating site. It also shows the divergent necessities of enabling verbalization for professional training, while ensuring a quiet and efficient environment for medical performance. To balance these requirements, we argue that dedicated briefing and debriefing sessions may be particularly effective; we also suggest that the self-confrontation video technique may be valuable to support the verbalization on both the mentor’s and the trainee’s side during such debriefing, and to enhance the mentor’s reflexivity regarding didactic choices.

Authors: Vertone Leonardo 
Published: March 2021

ZusammenfassungDer Beitrag stellt mit dem RADIP ein psychotherapeutisches Interventionsprogramm vor, das zum Ziel hat, das Fortschreiten von Radikalisierungsprozessen bei Jugendlichen zu verhindern (Deradikalisierung) und die Wahrscheinlichkeit einer Ausübung extremistischer Taten zu verringern (Distanzierung). Das Programm ist deliktpräventiv konzipiert und vereint forensische und kognitiv-verhaltenstherapeutische Methodiken. Es ist strukturiert und multimodal und kann im Einzel- oder im Gruppensetting durchgeführt werden. Nebst der Auseinandersetzung der Teilnehmenden mit Themen, die mit (ihrer) problematischen Radikalisierung in Verbindung stehen, beinhalten die Module Wissens- und Kompetenzzuwachs, Reflexion der eigenen Identität, Bewusstsein und Stärkung eigener prosozialer Ziele sowie Erhöhung der Entscheidungs- und Steuerungsfähigkeit (ressourcenorientierter Zugang). Bestandteil des Programms ist eine Abklärungsphase, welche eine psychiatrisch-psychopathologische und (entwicklungs-)psychologische Diagnostik sowie ein forensisches „risk assessment“ beinhaltet. Das daraus resultierende Fallverständnis erlaubt es, individuelle Schwerpunkte zu setzen und flexibel zu intervenieren. Das Programm ist in einen multisystemischen und -disziplinären Rahmen eingebettet, d. h., Eltern oder sonstige nahe Bezugs- sowie Hilfspersonen werden miteinbezogen.
Overall and diagnosis-specific sickness absence and disability pension in colorectal cancer survivors and references in Sweden
Authors: Beermann Luisa Christine , Alexanderson Kristina , Martling Anna , Chen Lingjing 
Published: March 2021

Abstract
Purpose
To longitudinally investigate overall and diagnosis-specific sickness absence (SA) and disability pension (DP) in colorectal cancer (CRC) survivors and references and to identify potential risk factors.

Methods
This longitudinal register-based cohort study included all patients living in Sweden, diagnosed with a first primary CRC in 2008–2011 when aged 18–62 (n=6679), and their matched references (n=26 716). Net days of SA (in SA spells >14 days) and DP were analyzed from 2 years before through 5 years after diagnosis, overall and by specific diagnoses. Among survivors, risk factors for future SADP were explored using logistic regression.

Results
In survivors, SA peaked in year 1 postdiagnosis, with 62.5% having at least some SA, and then gradually decreased to 20.1% in year 5. In the 2 years after diagnosis, CRC was the most common SA diagnosis in survivors, while SA due to mental diagnoses remained similar to the references. Notable risk factors for postdiagnostic SA or DP were rectal cancer diagnosis, advanced cancer stage at diagnosis, lower educational level, born outside of Sweden, and pre-diagnostic SA, mental morbidity, and comorbidities.

Conclusion
During 5 years after a CRC diagnosis, CRC survivors had higher levels of postdiagnostic SA and DP than the references, which was mostly due to CRC diagnoses. Although their SA lowered gradually, it did not return to pre-diagnostic levels.

Implications for Cancer Survivors
Our results provide valuable information for patients with CRC diagnosis, especially that most have none or low levels of SA/DP after a few years.

Opinion statementRecently introduced systemic therapies for locally advanced and metastatic non-melanoma skin cancers (NMSCs) are paving the way for neoadjuvant approach. Although none of the therapeutic options has currently gained indication in this setting, neoadjuvant approach for NMSCs is an open field and we are likely to see huge developments in the near future. Targeted therapy with sonic hedgehog pathway inhibitors is very effective in locally advanced or multiple basal cell carcinomas while immunotherapy with immune checkpoint inhibitors appears to be promising for advanced cutaneous squamous cell carcinoma and Merkel cell carcinoma. To date, targeted therapy and immunotherapy represent the frontiers in NMSC therapeutic management and, according to recent studies, good results can be achieved.
Human-Robot Handshaking: A Review
Authors: Prasad Vignesh , Stock-Homburg Ruth , Peters Jan 
Published: March 2021

AbstractFor some years now, the use of social, anthropomorphic robots in various situations has been on the rise. These are robots developed to interact with humans and are equipped with corresponding extremities. They already support human users in various industries, such as retail, gastronomy, hotels, education and healthcare. During such Human-Robot Interaction (HRI) scenarios, physical touch plays a central role in the various applications of social robots as interactive non-verbal behaviour is a key factor in making the interaction more natural. Shaking hands is a simple, natural interaction used commonly in many social contexts and is seen as a symbol of greeting, farewell and congratulations. In this paper, we take a look at the existing state of Human-Robot Handshaking research, categorise the works based on their focus areas, draw out the major findings of these areas while analysing their pitfalls. We mainly see that some form of synchronisation exists during the different phases of the interaction. In addition to this, we also find that additional factors like gaze, voice facial expressions etc. can affect the perception of a robotic handshake and that internal factors like personality and mood can affect the way in which handshaking behaviours are executed by humans. Based on the findings and insights, we finally discuss possible ways forward for research on such physically interactive behaviours.

AbstractDespite advances in coloanal anastomosis techniques, satisfactory procedures completed without complications remain lacking. We investigated the effectiveness of our recently developed ‘Short stump and High anastomosis Pull-through’ (SHiP) procedure for delayed coloanal anastomosis without a stoma. In this retrospective study, we analysed functional outcomes, morbidity, and mortality rates and local recurrence of 37 patients treated using SHiP procedure, out of the 282 patients affected by rectal cancer treated in our institution between 2012 and 2020. The inclusion criterion was that the rectal cancer be located within 4 cm from the anal margin. One patient died of local and pulmonary recurrence after 6 years, one developed lung and liver metastases after 2 years, and one experienced local recurrence 2.5 years after surgery. No major leak, retraction, or ischaemia of the colonic stump occurred; the perioperative mortality rate was zero. Five patients (13.51%) had early complications. Stenosis of the anastomosis, which occurred in nine patients (24.3%), was the only long-term complication; only three (8.1%) were symptomatic and were treated with endoscopic dilation. The mean Wexner scores at 24 and 36 months were 8.3 and 8.1 points, respectively. At the 36-month check-up, six patients (24%) had major LARS, ten (40%) had minor LARS, and nine (36%) had no LARS. The functional results in terms of LARS were similar to those previously reported after immediate coloanal anastomosis with protective stoma. The SHiP procedure resulted in a drastic reduction in major complications, and none of the patients had a stoma.
A generalized Anderson–Darling test for the goodness-of-fit evaluation of the fracture strain distribution of acrylic glass
Authors: Berlinger Marcel , Kolling Stefan , Schneider Jens 
Published: March 2021

AbstractAcrylic glasses, as well as mineral glasses, exhibit a high variability in tensile strength. To cope with this uncertainty factor for the dimensioning of structural parts, modeling of the stress-strain behavior and a proper characterization of the varying fracture stress or strain are required. For the latter, this work presents an experimental and mathematical methodology. Fracture strains from 50 quasi-static tensile tests, locally analyzed using digital image correlation, form the sample. For the assignment of an occurrence probability to each experiment, an evaluation of existing probability estimators is conducted, concerning their ability to fit selected probability distribution functions. Important goodness-of-fit tests are introduced and assessed critically. Based on the popular Anderson-Darling test, a generalized form is proposed that allows a free, hitherto not possible, choice of the probability estimator. To approach the fracture strains population, the combination of probability estimator and distribution function that best reproduces the experimental data is determined, and its characteristic progression is discussed with the aid of fractographic analyses.
When the Police Break the Law: The Investigation, Prosecution and Sentencing of Ontario Police Officers
Authors: Puddister Kate , McNabb Danielle 
Published: March 2021

AbstractCommunity trust in law enforcement and confidence in the administration of justice is put to the ultimate test when police officers act outside the limits prescribed by the criminal law. External and civilian oversight of the police can be essential to investigate and respond to allegations of police criminality and impropriety. However, little is known about the investigations completed by civilian oversight agencies and the prosecution of police officers. In this paper, we analyze 159 investigations by the Ontario Special Investigations Unit over a fifteen-year period. We examine each case from the laying of charges to prosecution through to sentencing. We provide an empirical analysis of how the justice system responds to police officers charged with a criminal offence. We situate these findings within the context of the broader justice system and police oversight. At the same time, we observe certain differences between the Canadian and American approaches to dealing with police offenders accused and convicted of criminal offences.
The classification of symmetry protected topological phases of one-dimensional fermion systems
Authors: Bourne Chris , Ogata Yoshiko 
Published: March 2021

Abstract
We introduce an index for symmetry-protected topological (SPT) phases of infinite fermionic chains with an on-site symmetry given by a finite group G. This index takes values in

$\mathbb {Z}_2 \times H^1(G,\mathbb {Z}_2) \times H^2(G, U(1)_{\mathfrak {p}})$

with a generalised Wall group law under stacking. We show that this index is an invariant of the classification of SPT phases. When the ground state is translation invariant and has reduced density matrices with uniformly bounded rank on finite intervals, we derive a fermionic matrix product representative of this state with on-site symmetry.
Comparative Nationalisms and Bibliographic Black Holes: The Case of the Turkmen of the North Caucasus
Authors: Condill Kit 
Published: March 2021

AbstractThe centuries-old Turkmen community of Stavropol’ Krai in southern Russia, while currently numbering only about 15,000 people, is an integral part of the famously diverse ethnolinguistic landscape of the North Caucasus. To the extent that Euro-Atlantic scholars have noted the existence of this community at all, their comments have been rather cursory and dismissive, and it has been claimed that the North Caucasus Turkmen (virtually alone among the dozens of similarly small ethnic groups of the region) have never published anything in their own language. Intensive investigations in the bibliographic record (and in secondary sources in Russian, Turkish, and Turkmen) show that this is not actually the case, and that the North Caucasus Turkmen do have a modest record of Turkmen-language publishing stretching back a century or more. What are the implications of these published works for our understanding of Turkmen identity, the Turkmen diaspora, and the complicated multiethnic and multilingual environment of the North Caucasus? What does it mean when groups like the North Caucasus Turkmen are made all but invisible in Euro-Atlantic scholarship and Euro-Atlantic library collections?
Regaining Control? The Political Impact of Policy Responses to Refugee Crises
Authors: Solodoch Omer 
Published: March 2021

AbstractIn response to the political turmoil surrounding the recent refugee crisis, destination countries swiftly implemented new immigration and asylum policies. Are such countercrisis policies effective in mitigating political instability by reducing anti-immigrant backlash and support for radical-right parties? The present study exploits two surveys that were coincidentally fielded during significant policy changes, sampling respondents right before and immediately after the change. I employ a regression discontinuity design to identify the short-term causal effect of the policy change on public opinion within a narrow window of the sampling period. The findings show that both Swedish border controls and the EU–Turkey agreement significantly reduced public opposition to immigration in Sweden and Germany, respectively. In Germany, support for the AfD party also decreased following the new policy. Public opinion time trends suggest that the policy effects were short lived in Sweden but durable in Germany. These effects are similar across different levels of proximity to the border and are accompanied by increasing political trust and a sense of government control over the situation. The findings have implications for understanding the impact of border controls on international public opinion, as well as for assessing the electoral effect of policy responses to global refugee crises.

Published: March 2021

AbstractRoads affect wildlife in a variety of negative ways. Road ecology studies have mostly concentrated on areas in the northern hemisphere despite the potentially greater impact of roads on biodiversity in tropical habitats. Here, we examine 4 years (January 2016–December 2019) of opportunistic observations of mammalian roadkill along a road intersecting Jozani-Chwaka Bay National Park, Unguja, Zanzibar. In particular, we assess the impact of collisions on the population of an endemic primate, the Endangered Zanzibar red colobusPiliocolobus kirkii. Primates accounted for the majority of roadkill in this dataset. Monthly rainfall was not associated with roadkill frequency for mammals generally, nor for the Zanzibar red colobus. No single age–sex class of colobus was found dead more often than expected given their occurrence in the local population. The overall effect of roadkill on colobus populations in habitats fragmented by roads is unknown given the lack of accurate, long-term life history data for this species. Our findings suggest that mortality from collisions with vehicles in some groups of colobus is within the range of mortality rates other primates experience under natural predation. Unlike natural predators, however, vehicles do not kill selectively, so their impact on populations may differ. Although a comparison with historical accounts suggests that the installation of speedbumps along the road near the Park's entrance has led to a significant decrease in colobus roadkill, further actions to mitigate the impact of the road could bring substantial conservation benefits.
