Umorzenie należności z tytułu składek na ubezpieczenia społeczne przy braku całkowitej nieściągalności – wybrane problemy
2021
Jednym z obowiązków w prawie ubezpieczeń społecznych jest opłacanie składek na ubezpieczenia społeczne. Ustawodawca przewidział, że w praktyce może się zdarzyć, że płatnik z różnych powodów nie będzie mógł uiścić należności składkowych. Wobec tego wprowadził określone mechanizmy, które mają ułatwić realizację tego obowiązku. Najdalej idącym z nich jest umorzenie należności z tytułu składek, które ma szczególny charakter w sytuacji, gdy nie istnieje stan ich całkowitej nieściągalności. To rozwiązanie ma charakter pomocowy, który może być istotny z uwagi na skutki pandemii COVID-19 dla przedsiębiorców. Celem artykułu jest przedstawienie wybranych problemów interpretacyjnych z zakresu stosowan…
Discovering hidden brain network responses to naturalistic stimuli via tensor component analysis of multi-subject fMRI data
2021
The study of brain network interactions during naturalistic stimuli facilitates a deeper understanding of human brain function. To estimate large-scale brain networks evoked with naturalistic stimuli, a tensor component analysis (TCA) based framework was used to characterize shared spatio-temporal patterns across subjects in a purely data-driven manner. In this framework, a third-order tensor is constructed from the timeseries extracted from all brain regions from a given parcellation, for all participants, with modes of the tensor corresponding to spatial distribution, time series and participants. TCA then reveals spatially and temporally shared components, i.e., evoked networks with the …
Mesoglea Extracellular Matrix Reorganization during Regenerative Process in Anemonia viridis (Forskål, 1775)
2021
Given the anatomical simplicity and the extraordinary ability to regenerate missing parts of the body, Cnidaria represent an excellent model for the study of the mechanisms regulating regenerative processes. They possess the mesoglea, an amorphous and practically acellular extracellular matrix (ECM) located between the epidermis and the gastrodermis of the body and tentacles and consists of the same molecules present in the ECM of vertebrates, such as collagen, laminin, fibronectin and proteoglycans. This feature makes cnidarians anthozoans valid models for understanding the ECM role during regenerative processes. Indeed, it is now clear that its role in animal tissues is not just tissue su…

Speed-Related Energy Flow and Joint Function Change During Human Walking.
2021
During human walking, mechanical energy transfers between segments via joints. Joint mechanics of the human body are coordinated with each other to adapt to speed change. The aim of this study is to analyze the functional behaviors of major joints during walking, and how joints and segments alter walking speed during different periods (collision, rebound, preload, and push-off) of stance phase. In this study, gait experiment was performed with three different self-selected speeds. Mechanical works of joints and segments were determined with collected data. Joint function indices were calculated based on net joint work. The results show that the primary functional behaviors of joints would n…

Implications of the COVID-19 pandemic on market orientation in retail banking
2021
AbstractThis qualitative study examines the implications of the COVID-19 pandemic on the implementation of market orientation (MO) in the context of retail banking. The findings show that MO was significantly reflected in the behaviors of banks upon encountering the COVID-19 situation, with the banks increasing their MO in response to the crisis. This study finds subcategories based on the empirical data that explain the implementation of MO in more detail. Overall, the findings provide valuable conceptual and managerial insights into the modus operandi of banks during a crisis and offer new best practices for the banking industry.
Whole-Body Magnetic Resonance Imaging: Current Role in Patients with Lymphoma.
2021
Imaging of lymphoma is based on the use of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) and/or contrast-enhanced CT, but concerns have been raised regarding radiation exposure related to imaging scans in patients with cancer, and its association with increased risk of secondary tumors in patients with lymphoma has been established. To date, lymphoproliferative disorders are among the most common indications to perform whole-body magnetic resonance imaging (MRI). Whole-body MRI is superior to contrast-enhanced CT for staging the disease, also being less dependent on histology if compared to 18F-FDG-PET/CT. As well, it does not require exposure to i…
Arsenic exposure and human blood DNA methylation and hydroxymethylation profiles in two diverse populations from Bangladesh and Spain.
2021
Abstract Background Associations of arsenic (As) with the sum of 5-mC and 5-hmC levels have been reported; however, As exposure-related differences of the separated 5-mC and 5-hmC markers have rarely been studied. Methods In this study, we evaluated the association of arsenic exposure biomarkers and 5-mC and 5-hmC in 30 healthy men (43–55 years) from the Aragon Workers Health Study (AWHS) (Spain) and 31 healthy men (31–50 years) from the Folic Acid and Creatinine Trial (FACT) (Bangladesh). We conducted 5-mC and 5-hmC profiling using Infinium MethylationEPIC arrays, on paired standard and modified (ox-BS in AWHS and TAB in FACT) bisulfite converted blood DNA samples. Results The median for t…
The phantoms of the opera—Stress offstage and stress onstage
2021
During opera performance singers deliver vocally demanding roles, follow a conductor, portray emotions of a musical work, act, dance, and engage with costumes, sets and props before an audience. Hence, opera performance is a stressful experience. This study examined different types of stress experiences by measuring the trajectories of 10 opera trainees’ heart rate variability (HRV) during two performances, covering onstage and offstage periods. We explored connections between HRV, self-reported stress measures, and expert-rated difficulty of the performed roles. We discovered that opera trainees had lower HRV and thus experienced greater physiological stress, while onstage compared to off…

2021
The presence of three species of the genus Anagyrus Howard (Hymenoptera: Encyrtidae) parasitizing the obscure mealybug Pseudococcus viburni (Signoret) (Hemiptera: Pseudococcidae) in agricultural ecosystems of citrus, persimmon and ornamental plants from Eastern Spain is recorded. Anagyrus aligarhensis Agarwal & Alam is recorded for the first time as parasitoid on this mealybug. Anagyrus fusciventris (Girault) is a new record for Spain. Anagyrus borrianensis sp. nov., reared as a specific primary parasitoid of this mealybug, is described and illustrated. The joint presence of Anagyrus pseudococci (Girault) and Anagyrus vladimiri Triapitsyn on citrus crops is confirmed. A key to species o…
Development and dissemination to operational stakeholders of integrative tools for chemical and biological measurements in watercourses to monitor th…
2021
The results of the Impact-CE project highlight the specific contribution of various integrative tools to have a more complete vision of the chemical and biological impact of pesticides on watercourses. In addition to grabe sampling, which gives a quantitative and instantaneous view of contamination, these tools provide more representative information over time, which makes them better tools for prioritising basins that contribute to contamination. They are also more robust for reporting interannual changes in agricultural practices, even if it may remain difficult to dissociate the effect of limited changes in practices from that of significant climatic variations. The results also confirm …

Bezprawny obrót znakami akcyzy jako czyn karnoskarbowy
2021
Niniejszy artykuł jest próbą rozkodowania normy prawnej z art. 70 k.k.s.1, która penalizuje bezprawny obrót znakami akcyzy jako czyn karnoskarbowy o charakterze przepołowionym, bo zarówno jako przestępstwo skarbowe, jak i jako wykroczenie skarbowe. Blankietowy charakter normy prawnej z art. 70 k.k.s. wymaga posiłkowania się przepisami innych ustaw celem pełnego ustalenia znaczenia użytych w jej treści pojęć i instytucji prawnych. Istota sprowadza się do tego, że swobodny obrót znakami akcyzy jest zakazany, a obrót nimi jest możliwy jedynie na zasadach stricte normatywnie, czyli prawnie określonych w treści odpowiedniej ustawy. Zgodnie z wolą ustawodawcy katalog osób uprawnionych do dysponow…
How Do Judgmental Overconfidence and Overoptimism Shape Innovative Activity?
2021
Recent field evidence suggests a positive link between overconfidence and innovative activities. In this paper we argue that the connection between overconfidence and innovation is more complex than the previous literature suggests. In particular, we show theoretically and experimentally that different forms of overconfidence may have opposing effects on innovative activity. While overoptimism is positively associated with innovation, judgmental overconfidence is negatively linked to innovation. Our results indicate that future research is well advised to take into account that the relationship between innovation and overconfidence may crucially depend on what type of overconfidence is most…

Andrés Febrés, linguista esule in Sardegna (1783 ca – 1790)
2021
Riassunto: L’arrivo in Sardegna dell’esule gesuita Andres Febres (Manresa, 1732 - Cagliari, 1790), in fuga da agenti dello Stato della Chiesa e dell’ambasciata spagnola a Roma, segna la ripresa di interessi linguistici gia espressi con l’Arte de la lengua general del reyno de Chile (Lima, 1765). Privo di mezzi materiali, operando da clandestino con il falso nome di Bonifacio d’Olmi, e in parallelo a un’attivita di stampa illegale, concepisce un progetto di pianificazione della lingua sarda, con una grammatica delle varianti del sardo e almeno un’opera in versi su cui sperimentare le sue innovazioni ortografiche, lessicali e morfologiche. Vorremmo ripercorrere il profilo di quell’esperimento…
Naturalization and spread of the alien species Ozognathus cornutus (LeConte, 1859) (Coleoptera: Ptinidae: Ernobiinae) in Italy
2021
AbstractOzognathus cornutus(LeConte, 1859) (Coleoptera: Ptinidae: Ernobiinae), species native to North America, is a saproxylophagous species and is known to feed on decaying tissues within conspicuous galls and on vegetal decaying organic material such as dried fruits or small wood shavings and insect excrements in galleries made by other woodboring species. A few years after the first record in 2011, its naturalization in Italy is here reported. The insect was found as successor in galls ofPsectrosema tamaricis(Diptera Cecidomyiidae),Plagiotrochus gallaeramulorum,Andricus multiplicatusandSynophrus politus(Hymenoptera Cynipidae).The galls seem to have played an important ecological role in…
Long- and short-range correlations and their event-scale dependence in high-multiplicity pp collisions at √s = 13 TeV
2021
Two-particle angular correlations are measured in high-multiplicity proton-proton collisions at √s = 13 TeV by the ALICE Collaboration. The yields of particle pairs at short-(∆η ∼ 0) and long-range (1.6 < |∆η| < 1.8) in pseudorapidity are extracted on the near-side (∆φ ∼ 0). They are reported as a function of transverse momentum (pT) in the range 1 < pT< 4 GeV/c. Furthermore, the event-scale dependence is studied for the first time by requiring the presence of high-pT leading particles or jets for varying pT thresholds. The results demonstrate that the long-range “ridge” yield, possibly related to the collective behavior of the system, is present in events with high-pT processes as well. Th…

Victor Hugo: la jeunesse d'un poète
2021
International audience; « Je veux être Chateaubriand ou rien ! » Cette note trahit les ambitions d’un jeune homme qui laissera après lui une œuvre monumentale. Il sera tout d’abord poète, encouragé par ses succès - une pension annuelle lui ayant été attribuée à 19 ans par Louis XVIII. À travers Les rayons et les ombres et Les feuillets d’automne, nous croiserons ses frères, Abel et Eugène ; sa femme, Adèle Foucher ; ses cinq enfants. Ce sont les cris d’un poète qui essaie déjà toute sa lyre, bien avant la mort de Léopoldine et l’exil. Tout un talent en germe. Un homme océan.

Il dynamic business modelling per lo sviluppo e la prevenzione delle crisi delle piattaforme multi-sided
2021
Over the last few decades, the sharing economy diffusion has implemented continu- ous changes in business model opportunities with multi-sided platforms (MSPs). MSPs are digital exchange platforms that connect unmatched demand and supply side participants through internet technology. Success examples of such businesses are Airbnb, Amazon, Uber, and Just Eat. How- ever, in many cases, such initiatives also experience high growth followed by a rapid failure. Due to MSPs peculiar and complex characteristics, this study suggests adopt- ing the dynamic business modeling (DBM) perspective. The DBM aims to make explicit reinforcing and balancing cause-and-effect relationships among strategic re- s…

Assessment of Cardiorespiratory Interactions during Apneic Events in Sleep via Fuzzy Kernel Measures of Information Dynamics
2021
Apnea and other breathing-related disorders have been linked to the development of hypertension or impairments of the cardiovascular, cognitive or metabolic systems. The combined assessment of multiple physiological signals acquired during sleep is of fundamental importance for providing additional insights about breathing disorder events and the associated impairments. In this work, we apply information-theoretic measures to describe the joint dynamics of cardiorespiratory physiological processes in a large group of patients reporting repeated episodes of hypopneas, apneas (central, obstructive, mixed) and respiratory effort related arousals (RERAs). We analyze the heart period as the targ…
Understanding the Role of Sensorimotor Beta Oscillations
2021
Beta oscillations have been predominantly observed in sensorimotor cortices and basal\ud ganglia structures and they are thought to be involved in somatosensory processing\ud and motor control. Although beta activity is a distinct feature of healthy and pathological\ud sensorimotor processing, the role of this rhythm is still under debate. Here we review\ud recent findings about the role of beta oscillations during experimental manipulations (i.e.,\ud drugs and brain stimulation) and their alteration in aging and pathology. We show how\ud beta changes when learning new motor skills and its potential to integrate sensory input\ud with prior contextual knowledge. We conclude by discussing a n…
