The Impact of COVID-19 on Road Freight Transport Evidence from Poland

Purpose: The main aim of this article is to investigate the impact of the COVID-19 pandemic on the Polish road freight transport industry. This paper seeks to understand the impacts on travel behavior and the transport system caused by the different actions and policies adopted by the governments and transport authorities to contain the COVID-19 spread. Design/Methodology/Approach: Econometric and statistical methods were used, including analysis ofprimary data, predictive model of exponential smoothing. Findings: Using primary data as part of the study, conclusions have been reached, stating that the imposition of the lock-down of the European economy had a negative impact on the shortterm business of transport enterprises. On the other hand, once the number of infections was reduced, followed by a reduction in restrictions, the number of road kilometers covered by the enterprises under survey increased. This increase was higher than in the corresponding periods of previous years. Practical Implications: The article analyses short-term effects on road freight transport of legal provisions aimed at limiting the virus's spread. Results can be helpful to draws some recommendations for transport systems derived and planning process by the enterprise. The researcher effect can also be helpful for national governments in terms of decision-making. Originality/Value: The literature review shows that most of the authors have focused on analyzing the situation of the road transport branch in China, while the impact of the coronavirus on road transport in Europe has not been studied to a more significant extent so far. The study of the case involves Polish transport enterprises making up the second-largest carrier in the Community when the size of its rolling stock and transport tasks is compared to that of other states. The consequences of the pandemic on road cargo transport by Polish carriers indicate the impact of COVID-19 on the economic situation of similar enterprises from other European Union states.

The objective of this study is to determine the macroeconomic determinants of income inequality in India and Pakistan. The study uses panel data from 1973 to 2015 and utilizes FEM model to estimate the parameter. Following general to specific methodology macroeconomic determinants of income inequality are found. The study finds the following macroeconomic variables as determinants of income inequality i.e. per capita GDP, government consumption expenditure, fertility rate, value addition by agricultural sector, per capita arable land, urban population, and globalization. Special attention must be given to reduce high fertility rate, especially in the lower class of the society.
Thermal shock fragmentation of Mg silicates within scoriaceous micrometeorites reveal hydrated asteroidal sources

Scoriaceous micrometeorites are highly vesicular extraterrestrial dust particles that have experienced partial melting during atmospheric entry. We report the occurrence of clusters of anhedral relict forsterite crystals within these particles that testify to in situ fragmentation. The absence of similar clusters within unmelted micrometeorites suggests that fragmentation occurs during atmospheric entry rather than by parent body shock reprocessing. Clusters of broken forsterite crystals are shown to form as a result of fracturing owing to thermal stress developed during entry heating and require thermal gradients of >200 K µm –1 in order for differential thermal expansion to exceed the critical shear strength of olivine. Thermal gradients of this magnitude significantly exceed those resulting from thermal conduction and require the endothermic decomposition of phyllosilicates. Fragmented relict forsterite within scoriaceous micrometeorites, therefore, indicate that the precursor grains were similar to CI and CM2 chondrites and retained phyllosilicate prior to atmospheric entry and thus were not dehydrated on the parent asteroid by shock or thermal metamorphism. Explosive fragmentation of hydrous asteroids during collisions, therefore, does not significantly bias the interplanetary dust population. of igneous rims on fine-grained MMs supports similar of saponite and serpentine. Experimentally determined reaction rates using the an activation energy E a of 521 kJ –1 a frequency factor A 4.3 10 24 were obtained by fitting to the data of Llana-Fúnez et al., (2007). The change in concentration of serpentine at each time step was used to determine the energy dissipated by dehydration using an enthalpy of reaction of 414 kJ kg –1 via 3 where C is the and is the order of reaction. Experimental studies suggest that the order of varies between and (Llana-Fúnez et al., 2007). A value was assumed in the current study. The transient heat flow was simulated using an implicit numerical integration with a time step of 1 × 10 −9 s and an element of 0.01 µm. Heat transfer by gas or melt migration is not considered in the model but is likely to be less important than conduction.
POLITICAL CONNECTION, FAMILY OWNERSHIP, AND EARNINGS MANAGEMENT IN MANUFACTURING COMPANIES IN INDONESIA

Political connections have an essential role in the earnings management strategy. Political connections can influence earnings management practices. The research aimed to analyze the effect of politics and family ownership on earnings management practices. The sample is 92 manufacturing companies listed on the Indonesia Stock Exchange for the period 2016-2019. Methods of data using a purposive sampling method. Multiple linear regression is an analytical tool used to test the hypothesis. The results show that political connections influence profits. The company pays more attention to the company’s reputation and maintains the privileges of the political relationship that has existed between the company and the government. Family ownership affects earnings management. Family ownership has control rights that can be used to influence management in company profits. The novelty of this research is that political connections can influence earnings management.
Mixed hp - FEM on anisotropic meshes

Mixed hp-FEM for incompressible fluid flow on anisotropic meshes are analyzed. A discrete inf–sup condition is proved with a constant independent of the meshwidth and the aspect ratio. For each polynomial degree k≥2 we present velocity-pressure subspace pairs which are stable on quadrilateral mesh-patches independently of the element aspect ratio, implying in particular divergence stability on the so-called Shishkin-meshes. Moreover, the inf–sup constant is shown to depend on the spectral order k like k-1/2 for quadrilateral meshes and like k-3 for meshes containing triangles. New consistency results for spectral elements on anisotropic meshes are also proved.
Revisit Multiple Intelligences with the Roles of Motivation, Strategy, and Anxiety in Foreign Language Learning—A Case Study in Taiwan

The study was conducted to revisit multiple intelligences with the roles of motivation, strategy, and anxiety in foreign language learning. Subjects were 260 Hospitality management major students in a private five-year junior college in north-eastern Taiwan, including 114 males and 146 females. They helped to fill out the 226-item questionnaires dealing with multiple intelligences [1] [2], motivation [3], strategy [4], and anxiety [5]. The results revealed that a correlation among multiple intelligences, motivation, strategy, and anxiety did exist, and led to different English levels. Discussions, implications, and suggestions for students, teachers, parents, and schools were provided.
PASTING PROPERTIES OF MODIFIED POTATO STARCH BY OZONE OXIDATION

Modified starches are widely used in the industry, since the modification provides properties that the native starches cannot offer. Further, there is a constant search for more efficient methods of modification, especially to replace the chemical ones, due to the waste generation. The ozone has a large oxidizing power and it can be used for food processing, since it is a safe and environmental friendly emergent technology, decomposing into oxygen without leaving residues. The present work modified potato starch in aqueous suspension (10% w/w) by oxidation with ozone. The peak and final apparent viscosities and the setback decreased with increasing treatment times, while the pasting temperature increased. The obtained results highlight the possibility of using ozone to desirably modify the potato starch properties. PALAVRAS-CHAVE: ozônio, amido, batata, propriedades de pasta, tecnologias emergentes
The Acquisition of Person Knowledge Annual Review of Psychology

How do we learn what we know about others? Answering this question requires understanding the perceptual mechanisms with which we recognize individuals and their actions, and the processes by which the resulting perceptual representations lead to inferences about people’s mental states and traits. This review discusses recent behavioral, neural and computational studies that have contributed to this broad research program, encompassing both social perception and social cognition.
Modeling of temperature-dependent shift of photoluminescence peak of In ( Ga ) As quantum dots considering acoustic and optical phonons as two oscillators

We demonstrate that all the available experimental data of temperature (T)-dependent shift of photoluminescence (PL) peak of In(Ga)As quantum dots (QDs) can be fitted successfully by using a two-oscillator model if and only if the whole temperature interval (0–300 K) is divided into a few parts (at most four parts), depending on dispersion degree of the PL peak from a monotonic behavior. Analysis of the numerical results show that excitons mostly interact (inelastically) with acoustic (AC) or optical (OP) phonons separately. Increasing QDs uniformity, by using some improved growth techniques, results in decreasing or removing the sigmoidal behavior, enhancing total AC phonon contribution and the maximum temperature that AC phonons contribute to the T-dependent redshift of the PL peak. Elevation of the zero bandgap (ZBG) energy up to a critical value about 1.4 eV, for In(Ga)As QDs grown using molecular-beam epitaxy, results in enhancement of QD symmetry and total OP phonon contribution and decline of QDs uniformity and total AC phonon contribution, while a rollover happens for further increase of the ZBG. Therefore we find that the highest QD symmetry and the lowest exciton fine structure splitting correspond to this critical value of ZBG, in accordance with previous experimental results. © 2014 Optical Society of America OCIS codes: (250.0250) Optoelectronics; (250.5230) Photoluminescence; (250.5590) Quantum-well, -wire and -dot devices; (160.0160) Materials. http://dx.doi. org/10.1364/JOSAB.99. 099999
Interpretation of ambiguous visual stimuli in depression : a behavioral response study

According to cognitive models of depression, negati ve biasing of cognitive resources is estimated to be central in the onset and maintenanc e of depressive symptoms. One scarcely researched bias in depression, the interpretative b ias, was the focus of this study. Previous research has indicated that depressed individuals h ve a tendency to favour negative evaluations even toward ambiguous stimuli. To test his hypothesis, our study examined whether dysphoric individuals would rate ambiguous visual stimuli as negative more often than the control group, and if there was a differen ce i reaction times according to blur level. Two groups, non-dysphoric and dysphoric, took part in an eye tracking experiment where negative and neutral pictures were shown starting f rom extremely blurred and ending in a completely clear image. The participants were asked to categorize each picture on each blur level (levels 1-4) as either negative or neutral. T he reaction time and categorization data were gathered. No difference between dysphoric and contr ol group was found in the analyses, and thus the existence of a negative interpretative bia s in dysphoria did not gain support. However, an increase in reaction times for both gro ups was found on blur level 3 towards negative pictures, in comparison to other levels (t he effect of blur and image valence on reaction time was highly significant on that level, p>.0001). This finding might reflect cognitive effort brought on by negative ambiguous s timuli.
Optimizing the Hyperparameter of Feature Extraction and Machine Learning Classification Algorithms

The process of assigning a quantitative value to a piece of text expressing a mood or effect is called Sentiment analysis. Comparison of several machine learning, feature extraction approaches, and parameter optimization was done to achieve the best accuracy. This paper proposes an approach to extracting comparison value of sentiment review using three features extraction: Word2vec, Doc2vec, Terms Frequency-Inverse Document Frequency (TF-IDF) with machine learning classification algorithms, such as Support Vector Machine (SVM), Naive Bayes and Decision Tree. Grid search algorithm is used to optimize the feature extraction and classifier parameter. The performance of these classification algorithms is evaluated based on accuracy. The approach that is used in this research succeeded to increase the classification accuracy for all feature extractions and classifiers using grid search hyperparameter optimization on varied pre-processed data.
Characterisation and Comparison of Process Chains for Producing Automotive Structural Parts from 7xxx Aluminium Sheets

Due to their high specific strength, EN AW-7xxx aluminium alloys are promising materials for reducing the weight of automotive structural parts. However, their formability at room temperature is poor due to pronounced natural ageing. Therefore, we investigated hot stamping and W-temper forming for EN AW-7075 and a modified variant of EN AW-7021. For hot stamping of the modified EN AW-7021, a low-temperature stabilisation heat treatment (pre-aging at 80 °C for 1 h) was incorporated into the process chain design to inhibit natural ageing after forming. The process chains were compared with respect to dimensional accuracy, mechanical properties, microstructure, precipitation status (assessed by differential scanning calorimetry) and crashworthiness. It was found that hot stamping is suitable to form failure-free parts with good dimensional accuracy for both alloys while W-temper forming suffers from springback. Within a time-span of 21 days after forming, hardness values of hot stamped and stabilised parts did not increase significantly. Compared to non-stabilised parts, stabilised parts also showed significantly improved folding behaviour in quasi-static compression testing and absorbed approximately 15% more energy.

Our study was done to observe the haematological profile of severe acute malnourished children admitted at P.B. M. Hospital Bikaner, Rajasthan. Material And Methods: This prospective observational study was designed for severe acute malnourished 178 children. Duration of this study was one year from 01.01. 2013 to 31.12. 2013. This study was done in special concern of haematological profile of severe acute malnourished children. Results: Our study showed that oedematous malnourished children had anaemia more common than non-oedematous malnourished children.Microcytic hypochromic anaemia and dimorphic anaemia were more common in non- oedematous and oedematous malnourished children. Conclusion: We concluded that Microcytic hypochromic anaemia and dimorphic anaemia is common in severe acute malnourished children. So, our primary target should be prevent malnourishment and secondary should be early diagnosis and management of sequelae by proper monitoring to avoid complications.
Title Learning from the problems of problem-based learning

Background: The last decade has witnessed a rapid expansion of biomedical knowledge. Despite this, fashions in medical education over the same period have shifted away from factual (didactic) teaching and towards contextual, or problem-based, learning (PBL). This paradigm shift has been justified by studies showing that PBL improves reasoning and communication while being associated with few if any detectable knowledge deficits. Discussion: Analysis of the literature indicates that the recent rapid rise of PBL has closely paralleled the timing of the information explosion. The growing dominance of PBL could thus worsen the problems of information management in medical education via several mechanisms: first, by creating the impression that a defined spectrum of core factual knowledge suffices for clinical competence despite ongoing knowledge expansion (quality cost); second, by dissuading teachers from refining the educational utility of didactic modalities (improvement cost); and third, by reducing faculty time for developing reusable resources to impart factual knowledge more efficiently (opportunity cost). Summary: These costs of PBL imply a need for strengthening the knowledge base of 21st-century medical graduates. New initiatives towards this end could include the development of more integrated cognitive techniques for facilitating the comprehension of complex data; the design of differentiated medical curricula for producing graduates with defined high-priority skill sets; and the encouragement of more cost-effective faculty teaching activities focused on the prototyping and testing of innovative commercializable educational tools. Background Many doctors have commented that their medical education began in earnest on the first day that they entered the hospital wards as a hands-on practitioner. Claims of this kind support the view that the apprenticeship model of professional learning – which has been the backbone of training in the healing arts for thousands of years [1] – remains as central to medical career development today as ever [2]. A perennial complaint of the medical apprenticein-training is that there are too few structured teaching activities within the busy world of postgraduate work [3], a concern which many institutions have addressed by developing formalised continuing education initiatives reminiscent of medical school courses [4-6]. Predictably, different complaints prevail at the pre-licensure phase of the training spectrum, where students often feel more motivated to acquire the (implicit) competence of the Published: 09 January 2004 BMC Medical Education 2004, 4:1 Received: 31 October 2003 Accepted: 09 January 2004 This article is available from: http://www.biomedcentral. com/1472-6920/4/1 © 2004 Epstein; licensee BioMed Central Ltd.

300-kW Solar Electric Propulsion System Configuration for Human Exploration of Near-Earth Asteroids

The use of Solar Electric Propulsion (SEP) can prov ide significant benefits for the human exploration of near-Earth asteroids. These benefit s include substantial cost savings ‐ represented by a significant reduction in the mass required to be lifted to low Earth orbit ‐ and increased mission flexibility. To achieve these benefits, system power levels of 100’s of kW are necessary along with the capability to store and process tens of thousands of kilograms of xenon propellant. The paper presents a conceptual design of a 300-kW SEP vehicle, with the capability to store nearly 40,000 kg of xenon, to support human missions to near-Earth asteroids.
Assessment of microbiological quality of khebab sold on the campus of a tertiary education and its environs in Ghana

Prevalence and incidence of foodborne illness in developing countries has risen in recent times as a result of increased demand for Ready-To- Eat (RTE) foods. The current study assessed the microbiological quality of khebab sold at selected areas within the Kumasi metropolis. A total of 36 khebab samples were purchased and analyzed for Total Viable Count (TVC), Total Coliforms Count (TCC) and Thermotolerant Coliforms Count (TTC). The results showed that the mean TVC, TCC and TTC in beef khebab at the different locations ranged from 6.91- 7.23 Log10 CFU/g, 7.25-9.23 Log10 MPN/g and 4.97-7.75 Log10 MPN/g respectively. For chevon khebab, it ranged from 6.83-7.25 Log10 CFU/g, 7.98 - 9.23 Log10 MPN/g and 6.61-8.81 Log10 MPN/g respectively. That of gizzard khebab ranged from 6.89-7.30 Log10 CFU/g, 7.98-9.23 Log10 MPN/g and 6.89-7.53 Log10 MPN/g respectively. The mean TVC, TCC and TTC for the beef khebab were not significant (p = 0.680, 0.055 and 0.070) respectively. For the chevon, the TVC and TCC were not significant (p = 0.547 and 0.121) respectively but that of the TTC was significant (p = 0.034). The mean TVC, TCC and TTC of the gizzard were not significant (p = 0.794, 0.056 and 0.822) respectively at the different locations. These mean microbial loads (TVC, TCC and TTC) in the khebab samples exceeded the standard acceptable limits (? 5 Log CFU/g and ? 2 Log10 MPN/g). Since the microbial loads exceeded the standard acceptable limits, it could put consumers at high risk of contracting foodborne infection. This result should prompt the relevant institutions responsible for ensuring food safety in the metropolis to strictly enforce the standard regulations on food safety practices as well as carry out adequate monitoring to avoid possible foodborne infections. Key words: Khebabs, total viable count, total coliforms count, thermotolerant coliforms count.
Transformation Kinetics of Bainite during Isothermal Holding and Continuous Cooling

The isothermal and continuous cooling transformation kinetics of bainite were studied using an automatic quench dilatometer. It was found that the overall isothermal bainite transformation kinetics were well expressed by Johnson-Mehl type equation and that the transformation rate decreased with increase in the austenite grain size. The analysis of transformation kinetics and the optical microscope observations suggested that the nucleation site of bainite was both on the grain boundaries and inside the austenite grain. This effect of austenite grain size on the rate of isothermal transformation to bainite was found to be smaller than that to pearlite. Comparison of the observed cooling transformation kinetics with that predicted from the isothermal kinetic data showed that the transformed fractions were additive in bainite transformation. This result might be understood if it were assumed that the bainite transformation proceeds with repeated nucleation and growth of basic subunits, each attaining the limit size rapidly.
Correlation Filter Correlation Filter ( a ) Unsupervised Learning Motivation Template Patch Search Patch Search Patch Template Patch Forward Tracking using Initial Label Backward Tracking using Pseudo Label Consistency

We propose an unsupervised visual tracking method in this paper. Different from existing approaches using extensive annotated data for supervised learning, our CNN model is trained on large-scale unlabeled videos in an unsupervised manner. Our motivation is that a robust tracker should be effective in both the forward and backward predictions (i.e., the tracker can forward localize the target object in successive frames and backtrace to its initial position in the first frame). We build our framework on a Siamese correlation filter network, which is trained using unlabeled raw videos. Meanwhile, we propose a multiple-frame validation method and a cost-sensitive loss to facilitate unsupervised learning. Without bells and whistles, the proposed unsupervised tracker achieves the baseline accuracy of fully supervised trackers, which require complete and accurate labels during training. Furthermore, unsupervised framework exhibits a potential in leveraging unlabeled or weakly labeled data to further improve the tracking accuracy.
