Monitoring of digital transformation risks as a key policy to prevent future financial crises
Authors: Afanasiev Andrey , Kandinskaia Olga
Published: December 2021

The digital transformation of finance has been significantly facilitated by the COVID-19 pandemic, and it has become the dominant trend and the driving force of development in the upcoming years. The digital transformation brings not only benefits to financial markets, people, companies, and institutions, but it also results in dramatic changes of the underlying risks. The nature, mechanisms, and scale of financial crises are bound to change substantially. The paper develops a new, forward-looking approach to financial crises research. We build further upon the multidisciplinary research agenda on digital transformation by Verhoef et al. (2021). Achieving a bright digital future requires knowing and managing the adverse effects of digitalisation (Clim, 2019; Dickson, 2019; Gimpel & Schmied, 2019). Our literature search has not found any studies on digital transformation risks as a key policy to prevent future financial crises. The purpose of this paper is to examine the existing system of risks monitoring, to analyse changes in risks due to the digital transformation in finance, and to provide policymakers with insights regarding the related evolution of risks. This paper is a policy analysis type of research containing a systematic overview of risk assessment reports at the global and the EU levels.

Introduction: It has been reported that ventricular tachycardia (VT)
non-inducibility at the end of ablation is associated with less likely
VT recurrence. However, it is not clear whether we should use VT
non-inducibility as routine end point in VT ablation. The aim of this
study was to evaluate VT recurrence in patients in whom VT
non-inducibility could not be achieved at the end of the RF ablation and
the factors attributing to the VT recurrence. METHODS and RESULTS: We
analyzed 84 consecutive patients that underwent RF ablation, and 64
patients in whom VT non-inducibility could not be achieved were studied.
The primary endpoint was recurrence of any sustained VT during the
follow-up. During a median follow-up period of 1.4 years (IQR:0.3-2.0),
22 (34%) of the cases had VT recurrences. In the multivariate analysis
showed that an LVEF≥35% (HR:0.21; 95% CI:0.07- 0.54; P<0.01)
and successful identification and ablation of all clinical VT isthmuses
(HR:0.21; 95% CI:0.03- 0.72; P=0.01) were independent predictors of
fewer VT recurrences. RF ablation was associated with a 91.1% reduction
in VT episodes. CONCLUSION: Even if VT non-inducibility could not be
achieved, the patients with LVEF≥35% or in whom all clinical VT
isthmuses could successfully be identify and ablated might be prevented
from having VT recurrences. The validity of VT non-inducibility of any
VT should be evaluated by each patient’s background and the results of
the procedure.
Conservation and Management of the Culture of Bears
Authors: Servheen Christopher , Gunther Kerry
Published: December 2021

ABSTRACT: Culture is widely accepted as an important social factor
present across a wide range of species. Bears have a culture as defined
as behavioral traditions inherited though social learning usually from
mothers to offspring. Successful bear cultures can enhance fitness and
resource exploitation benefits. In contrast, some bear cultures related
to response to humans and human-related foods can be maladaptive and
result in reduced fitness and direct mortality. In environments with
minimal human influence most bear culture has evolved over generations
to be beneficial and well adapted to enhance fitness. However, most
bears across the world do not live in areas with minimal human influence
and in these areas, bear culture is often changed by bear interactions
with humans, usually to the detriment of bear survival. We highlight the
importance of identifying unique bear cultural traits that allow
efficient use of local resources and the value of careful management to
preserve these adaptive cultural behaviors. It is also important to
select against maladaptive cultural behaviors that are usually related
to humans inorder to reduce human-bear conflicts and high bear
mortality. We use examples from Yellowstone National Park to demonstrate
how long-term management to reduce maladaptive bear cultures related to
humans has resulted in healthy bear populations and a low level of
human-bear conflict in spite of a high number of Park visitors in close
association with bears.
Confirmation Bias and Auditor Risk Assessments: Archival Evidence
Authors: Cassell Cory A. , Dearden Stuart M. , Rosser David M. , Shipman Jonathan E.
Published: December 2021

Judgment and decision-making research suggests that auditors' judgments are negatively affected by the use of heuristics. However, there is little research investigating whether such biases survive the quality control processes that regulators and audit firms implement to mitigate them. We investigate this by identifying a setting where one such bias—confirmation bias—is likely to manifest. Consistent with confirmation bias influencing observable audit outcomes, we find that auditors with previous experience auditing a client with a history of low risk followed by an increase in risk do not adequately respond to the higher level of risk. This effect is mitigated when the risk increase is likely large enough to violate auditors' reasonableness constraint and when the client is highly visible or has strong external monitors. Our study complements prior experimental research by providing archival evidence that auditors' use of heuristics has a significant effect on auditor judgments.

Is an Emoji Worth a Thousand Words? The Effect of Emoji Usage on Nonprofessional Investors' Perceptions
Authors: Carrillo Hilda E. , Pennington Robin , Zhang Yibo (James)
Published: December 2021

Emojis act as non-verbal cues to disambiguate and communicate affect and are increasingly used in online corporate disclosures. Emotion work, a concept founded in social psychology, suggests that individuals adjust their behavior as emotions are evoked or suppressed. Despite the growing evidence that emojis may influence judgments and decisions due to their deliberate expression of context and affect, the accounting research community has yet to investigate emojis' impact. We experimentally explore whether emojis can soften nonprofessional investors' perceptions of bad news or enhance perceptions of good news. We find that emojis modestly suppress participants' positive emotions on positive news, influencing their investment-related judgments and decision-making. Subsequent data collection fails to replicate the initial findings in a less experienced participant pool, suggesting that investing experience may play a role. Our study enhances our understanding of the unintended consequences of emojis and introduces a sociology-based principle into the accounting literature.

Targeting the Pancreatic α-Cell to Prevent Hypoglycemia in Type 1 Diabetes
Authors: Panzer Julia K. , Caicedo Alejandro
Published: December 2021

Life-threatening hypoglycemia is a limiting factor in the management of type 1 diabetes. People with diabetes are prone to develop hypoglycemia because they lose physiological mechanisms that prevent plasma glucose levels from falling. Among these so-called counterregulatory responses, secretion of glucagon from pancreatic α-cells is preeminent. Glucagon, a hormone secreted in response to a lowering in glucose concentration, counteracts a further drop in glycemia by promoting gluconeogenesis and glycogenolysis in target tissues. In diabetes, however, α-cells do not respond appropriately to changes in glycemia and, thus, cannot mount a counterregulatory response. If the α-cell could be targeted therapeutically to restore its ability to prevent hypoglycemia, type 1 diabetes could be managed more efficiently and safely. Unfortunately, the mechanisms that allow the α-cell to respond to hypoglycemia have not been fully elucidated. We know even less about the pathophysiological mechanisms that cause α-cell dysfunction in diabetes. Based on published findings and unpublished observations, and taking into account its electrophysiological properties, we propose here a model of α-cell function that could explain its impairment in diabetes. Within this frame, we emphasize those elements that could be targeted pharmacologically with repurposed U.S. Food and Drug Administration–approved drugs to rescue α-cell function and restore glucose counterregulation in people with diabetes.

Authors: ŞAHİNASLAN Apdulmutalip , BURUNTEKİN Mehmet , ÖZTOP Mesut
Published: December 2021

Parabolic solar collectors with central receiving systems are preferred due to their high efficiency despite their high initial investment and operating costs. In this study, the effect of two glass covers on tubular collector will be investigated, aiming enhancement of cylindrical parabolic solar collectors’ efficiency. By using glass cover it is aimed to decrease losses and increase efficiency. In order to investigate the changes of losses and instantaneous efficiency, a model was constructed considering all parameters of the structure, optical losses, material properties and outdoor climatic conditions. Results of calculations show that the two-cover system is not more efficient than the single cover system at low fluid temperatures between 0 and 500 K and the efficiency of the two-cover system is increased at medium fluid temperatures between 500 and 700 K.
Ja eller nei til Huawei? En analyse av hvordan små og mellomstore stater stiller seg til den kinesiske gigantens rolle i 5G
Authors: Christie Øystein
Published: December 2021

Artikkelen ser på den teknologiske og strategiske rivaliseringen mellom USA og Kina hva gjelder implementeringen av 5G-nettverk, og spør hva som er med å påvirke hvordan andre stater posisjonerer seg mellom de to supermaktene. Ved å bygge på tre grener av politisk realisme – balance-of-threat-teoriens tanke om at trusseloppfatning driver staters valg av allianser, patron–klient-teoriens tro på at USA kan forvente at deres klientstater innretter seg etter amerikansk utenrikspolitikk, og teorien om at handelsrelasjoner kan brukes som maktverktøy – utleder jeg et sett med hypoteser og potensielt relevante forklaringsvariabler. Som avhengig variabel samler jeg 70 staters holdninger til Kinas omstridte telekommunikasjonsgigant Huaweis rolle i 5G. Bivariat analyse avslører tre hovedmønstre: (1) Stater som er små og maktesløse i forhold til Kina, samt statene i Kinas geografiske region, ser ut til å være mer aksepterende til Huaweis 5G. (2) Stater som ser på USA som sin patron og som er avhengige av Washingtons sikkerhetsgaranti ser ut til å være betydelig mer avvisende til selskapets 5G. (3) Handelsrelasjoner til både USA og Kina ser ut til å ha liten eller ingen effekt på staters holdninger. Av de tre realisme-grenene er det altså patron–klient-teorien som veier tyngst når det gjelder å forklare staters holdninger til Huaweis 5G.
Abstract in English:The US way or the Huawei: An analysis of how small and medium states stand on the Chinese giant’s role in 5GThis article examines the technological and strategic rivalry between the US and China on the implementation of 5G networks, asking what influences how other states position themselves between the two superpowers. By building on three branches of political realism – balance-of-threat theory’s notion that perception of threat drives states’ alliance choices, patron-client theory’s belief that the US can expect its client states to adhere to American foreign policy, and the theory that trade relations can be used as power tools – I derive a set of hypotheses and potentially relevant explanatory variables. As dependent variable, I measure 70 states’ stances on China’s controversial telecom giant Huawei’s role in 5G. Bivariate analysis reveals three primary patterns: (1) States who are dwarfed by China’s power, as well as states in China’s immediate geographic region, appear to be more acceptive of Huawei’s 5G. (2) States who see the US as their patron and who rely on Washington’s security guarantee appear to be much more rejective of the company’s 5G. (3) Trade relations to both the US and China appear to have little or no effect on states’ stances. Of the three branches of realism, it is the patron-client theory that offers the most weight in explaining states’ stances on Huawei’s 5G.

In the cytokinesis-block micronucleus (CBMN) assay, micronuclei (MNi), nucleoplasmic bridges (NPBs), and nuclear budding (NBUD) are the most commonly analysed morphological types of nuclear abnormalities. In contrast, tailed and dumbbell-shaped nucleus have historically received little attention in the CBMN assay. Interestingly, the incidence of tailed and dumbbell-shaped nuclei in lymphocytes is closely related with that of dicentric chromosomes or NPBs in the CBMN assay. To provide a better picture of the implications and significance of tailed and dumbbell-shaped nuclei as markers of radiation exposure, a literature review was performed in this study. Twenty articles were found in PubMed, PubMed Central, and manually searched. The articles were screened and those that met the inclusion criteria and did not meet the exclusion criteria were reviewed by all authors. At the end, nine articles were included. In conclusion, the assessment of in vivo tailed nuclei in blood smears and accounting for the occurrence of dumbbell-shaped nuclei in the CBMN assay can increase the sensitivity of the CBMN assay for biodosimetry involving a high dose exposure.
Legal Aspects of Incorporation of Clause Paramount in Time Charters, Voyage Charters and Bills of Landing
Authors:   , Shchukin Artem
Published: December 2021

The main purpose of this thesis is to examine the effect of a clause paramount in bills of lading and charterparties and to clarify how this clause is interpreted by English courts. The primary complexity that arises in the bill of lading context comes from the scope of the incorporated Hague or Hague-Visby Rules, which depends on the different variants of clause paramount, applicable statute and the country of shipment. In the charter party context, a clause paramount has created a great deal of difficulty with the construction of contracts, especially in regard to the significance of the word “paramount” and the extent to which the incorporated articles override other provisions in a charterparty. The thesis is divided into two parts: Part One is focused on the structure and interpretation of the Hague Rules as an international treaty. It examines the purpose of a clause paramount, based on its wording and different scenarios, and deals with contractual interpretation when the Rules are given effect by “force of law” or incorporated purely by contract. Part Two investigates the way how a Clause Paramount, when incorporated in the contract, affects the parties’ rights and obligations. It specifically deals with the fundamental obligation of seaworthiness and the secondary functions of the carrier. It examines the protection of third parties and investigates the interplay of Clause Paramount with the terms of the Inter-Club Agreement.
Characterisation of the ghrelinergic system in human models of neurodegenerative diseases
Authors:   , Carisì Maria C.
Published: December 2021

Calorie restriction (CR) has well established neuroprotective properties across species and is known to prevent cognitive deficits in several mouse models and in aged humans. Our group and others have shown that CR beneficial effects are dependent on the circulating hormone acyl-ghrelin (AG), that promotes hippocampal memory function and protects against neurodegeneration in rodents. Indeed, ghrelin knockout (KO) mice show defects in memory task performance and plasma ghrelin levels are significantly reduced in aged humans. Because of its connection to memory and ageing, AG has been studied in mouse models of Alzheimer’s disease (AD) and Parkinson’s disease (PD), the two most common causes of dementia in the aged population. However, very few of these studies have been performed in human models. This project aimed to determine the expression of key regulatory proteins of the ghrelin pathway in the young and aged healthy human brain, as well as brain of AD and PD patients, combining immunohistochemistry, RNA in situ hybridization, and molecular biology. My findings show that the key enzymes of the ghrelinergic axis – GHS-R1a, GOAT and APT1 – are highly expressed in the aged healthy human hippocampus, but their expression level is impaired in PD with dementia . Further studies are needed to determine a potential correlation between the activity of ghrelin in the brain and the level of cognitive impairment and dementia. On the contrary, very little difference is observed between early and late stage of AD, suggesting that the ghrelinergic system may not be impaired in these patients. The second aim was to characterize the effects of AG on a human neuronal cell line treated with rotenone or amyloid-β oligomers (AβOs) to simulate oxidative stress from PD and AD, respectively. Using confocal microscopy and molecular biology techniques, I assessed neuronal cell death and mitochondrial function and reported significant mitochondrial toxicity in these models, that worsen by chronic pre-treatment with the inactive form of AG, unacylated ghrelin (UAG). Ultimately, this project supports the ghrelinergic axis as a potential target for future studies aiming to identify treatments to limit the progression of dementia in humans.

O presente trabalho busca analisar o processo de absorção das ocupações secundaristas em Goiás por parte do Estado. Para tanto, passa-se a direcionar o estudo a partir da perspectiva dos próprios estudantes e dessa forma busca-se entender e explicar os processos que culminaram no fim das ocupações. Dessa maneira, recorre-se à pesquisa bibliográfica e à pesquisa documental, de modo que seja possível compreender os fenômenos sociais inseridos nesse processo de luta e o desenvolvimento da ação do Estado nas ocupações. A partir disso, buscamos analisar as denúncias perpetradas pelos próprios estudantes por meio das páginas das ocupações. Outra questão importante analisada no presente trabalho, trata-se de apresentar a forma de organização do movimento secundarista em Goiás que cotidianamente afirmava e reafirmava seu caráter autogestionário. Concomitantemente, compreende-se à tática enquanto aspecto micro da estratégia. A tática é compreendida enquanto conjunto de ações que são utilizadas para alcançar determinado objetivo. Dentro disso, observa-se quatro estágios que se desenvolveram para que o Estado pudesse pôr fim às ocupações secundaristas contra a privatização e a militarização do ensino público. Por fim, conclui-se que, embora o Estado tenha absorvido e posto fim ao método de ocupação enquanto forma de reivindicativa, também desenvolveu mecanismos para que esse método de organização deixasse de existir. Dessa maneira, o presente trabalho permite compreender a relação entre Estado, Violência e Movimentos Sociais, permitindo uma compreensão mais profunda e prática das relações e inter-relações que permeiam esse processo.

Calcareous nannofossils from the middle/upper Miocene succession of Pécs-Danitzpuszta, southern Hungary: cosmopolitan Paratethys and endemic Lake Pannon assemblages
Authors: Ćorić Stjepan
Published: December 2021

Quantitative analyses on calcareous nannofossils were carried out on 109 middle/late Miocene (Sarmatian/ Pannonian) samples from the section at Pécs-Danitzpuszta sand pit (Hungary). The lower part of the section, which can be assigned to the Sarmatian, contains normal marine low-diversity assemblages dominated by Calcidiscus leptoporus, Reticulofenestra pseudoumbilicus, Sphenolithus moriformis and Syracosphaera spp. accompanied by didemnid ascidian spicules (Perforocalcinela fusiformis). The middle/late Miocene (Sarmatian/Pannonian) boundary is characterized by the last occurrences of normal marine calcareous nannofossils. The upper part of the section (Pannonian) can be subdivided into intervals characterized by monospecific endemic nannofossils Isolithus spp. and ascidians, respectively. A short interval with common endemic coccoliths belonging to the family Noelaerhabdaceae (Bekelithella echinata, Noelaerhabdus bozinovicae, N. jerkovici, Praenoelaerhabdus banatensis) in the upper part of the profile was also documented. The drastic change in nannofossil assemblages at the Sarmatian/Pannonian boundary is a result of paleoenvironmental stress caused by the isolation of the Central Paratethys from the Eastern Paratethys.
Various marginal marine environments in the Central Paratethys: Late Badenian and Sarmatian (middle Miocene) marine and non-marine microfossils from Pécs-Danitzpuszta, southern Hungary

Published: December 2021

The middle Miocene foraminifera and ostracod record of the Central Paratethys usually reflects stable normal marine epositional environments for the Badenian and more patchy, less stable restricted marine environments for the Sarmatian. A 17 m thick outcrop at Pécs-Danitzpuszta, Mecsek Mts, SW Hungary exposed an upper Badenian to Pannonian succession where foraminifers and ostracods document significant environmental changes. The basal layers of the section contain micro- and macrofossils indicating normal marine, shallow, warm, well-oxygenated habitat with relatively high-energy conditions and algal vegetation on the bottom, and represent the upper Badenian (13.82 to 12.65 Ma). The marine deposits are followed by coarse sandstone, breccia and siltstone layers barren of microfossils but containing rhizoliths. The sediments were probably subaerially exposed for some time. The following marine inundation, marked by the appearance of clays and limestones as well as fossils, was dated to the late Sarmatian (ca. 12 to 11.6 Ma) on the basis of the restricted marine microfossil assemblages from the upper part of the succession (Porosononion granosum Zone, Aurila notata Zone). This community is characterized by exclusively eurytopic forms indicating an unstable and vegetated marginal marine environment with fluctuations in salinity, as well as oxygen and food availability. Within the 5 m thick upper Sarmatian marine interval, a unique fresh- to oligohaline fauna characterizes a few layers in less than 1 m thickness. This fauna consists of highly euryhaline foraminifera and freshwater to oligohaline ostracod assemblages, indicating a temporary salinity reduction to 5–10 ‰. No similar freshwater fauna has been reported from the Sarmatian of the Central Partethys so far. The eventual disappearance of the foraminifera from the paleontological record coupled with a complete turnover in the ostracod fauna indicates the transition from the marginal marine Sarmatian Sea to the brackish Lake Pannon, marking the Sarmatian/Pannonian boundary (11.6 Ma).
Selection of a method for calculating heat gain from solar radiation to determine the load on the climate system of the cabin of a mobile car
Authors: Maslenskiy Viktor V.
Published: December 2021

Introduction. The article analyzes and selects the most rational methods for calculating the heat gain from solar radiation. The correct calculation of this component of the heat balance allows you to correctly determine the power of the projected cabin climate system, which will ensure optimal working conditions at the workplace of mobile car operators.
Problem Statement. The objective of this study is to analyze and select a rational method for calculating heat gain from solar radiation for the correct determination of the thermal load on the climate system of the cabin of a mobile car.
Theoretical Part. To implement the task, the most common methods for calculating solar radiation were described and analyzed in detail and the most accurate ones were recommended.
Conclusions. The more labor-intensive method of V.N. Bogoslovskiy (taking into account the time of day) can be recommended for automated calculations in Excel, and the method of P.Y. Gamburg (taking into account the sides of the horizon) — for comparative estimated engineering calculations. When conducting "in-depth" model calculations and accounting for solar radiation, the ASHRAE method is explicitly suitable, which has two important advantages: it takes into account the solar factor in relation to a specific type of glazing and is adapted for automated calculations in ANSYS FLUENT.
