This research aims to examine the covid-19 pandemic measurements taken in maritime transport and their possible effects on the supply-demand equilibrium and consequently on the freight market. Covid-19 virus which infected quite large geographic area and people within very short time affects negatively not only every part of our life but also the production and service sector within the globalised world.  This is mainly because the future tendency and further effects of this virus are unpredictable. Because of that, most countries are focused firstly on measurements to be taken to reduce the spreading speed of the virus. Although measurements and restrictions seem reduced spreading speed in some countries in short term, those measurements increase the operating costs of production and service companies. On the one hand reduction on cargo movements due to low demand and increasing operation cost due to measurements, have effected the supply-demand equilibrium of maritime transportation. This research examined the effects of already taken and could be revised measurements due to the present situation and possible future tendency of covid-19, and its consequential results on the freight market.

A pandemic is a contagious disease outbreak that happens over a large geographic area and affects a great portion of the population while new pathogens appear for which people have less immunity and no vaccines are available. The disease can spread from person to person in a very short time. Health workers are at greater risk of infection because of patients who are carriers. In the 21st century, where everyone is connected through digital technologies, information and communication technology (ICT) plays a critical role in improving healthcare for individuals and larger communities. ICT can be divided into a wide variety of application domains that signify its importance as a major technological paradigm. It is currently drawing large attention because of its potential to alleviate the burden on healthcare systems caused by the rise in chronic diseases, aging populations and pandemic situations. This study surveyed substantial knowledge on how effective ICT healthcare solutions can be used towards managing global pandemics. In order to make it more comprehensive, we also present a four-phase strategic framework that can be deployed to alleviate the strain on healthcare resources during a pandemic, which was derived from the reviewed literature. Further, we also discuss how ICT technologies can be used towards managing pandemic situations chronographically during the transformation from a simple disease outbreak into a global pandemic.

The paper analyzes changes in job opportunities of older workers in Russia in the period 2005—2017. The study uses the data from the Russian Labor Force Survey conducted by Rosstat. Changes in the occupational and industrial composition of elderly workers follow the trends pursued by other age groups: employment shifts from low- to high-skilled occupations, from physical to intellectual labor, and from material production to the service sector. We find a stronger polarization among older workers as their occupational structure is biased in favor of, on the one hand, the most and, on the other hand, the least qualified types of jobs. Employment of the elderly has fallen sharply in agriculture and manufacturing with a significant increase in trade, education, and health. Although the employment structure of older workers is generally more “traditionalist”, recent decades have witnessed its transformation in “progressive” directions, similarly to other age groups. These findings suggest that the legislated increase in the state retirement age is not likely to give rise to sizeable unemployment among the elderly. Most of them will be able to work in the occupations and industries previously dominated by young and prime-age workers.

Abstract The Educator as a Manager. A Critical View In the following article tasks and motifs of the educator as manager are described. It is clear that there are other educator metaphors and associated behaviors. To some extent, the actions of the different educator metaphors overlap, but they differ in their purpose and perspective on the educational process and the person to be educated. First, a short time diagnosis is made, which describes the context of this metaphor of the educator as manager. Subsequently, on the one hand, the various motifs, tasks and objectives of an educator as manager are discussed. On the other hand, it is asked if it is possible in the current discourse to take a different perspective on the educational process.

This study discusses convolutional neural networks (CNNs) for vibration signals analysis, including applications in machining surface roughness estimation, bearing faults diagnosis, and tool wear detection. The one-dimensional CNNs (1DCNN) and two-dimensional CNNs (2DCNN) are applied for regression and classification applications using different types of inputs, e.g., raw signals, and time-frequency spectra images by short time Fourier transform. In the application of regression and the estimation of machining surface roughness, the 1DCNN is utilized and the corresponding CNN structure (hyper parameters) optimization is proposed by using uniform experimental design (UED), neural network, multiple regression, and particle swarm optimization. It demonstrates the effectiveness of the proposed approach to obtain a structure with better performance. In applications of classification, bearing faults and tool wear classification are carried out by vibration signals analysis and CNN. Finally, the experimental results are shown to demonstrate the effectiveness and performance of our approach.

At present there are few studies on the AVS and SEM in sediments of Chaohu Lake. Most of the previous studies on heavy metals based on the one time, the short-time or a local-scale survey. In this paper, [AVS] and [SEM] in Chaohu Lake surface sediments were studied for different seasons in 2007, 2008 and 2009. The results showed that: (a) The three-year average of [AV and [ΣSE in surface sediments of Chaohu Lake is 4.2μmolg-1and 2.31μmolg-1, respectively. The maximum of [AV appears on spot 5 (14.845μmolg-1) in summer while the minimum appears on spot 9 (0.13μmolg-1) in winter. (b) In spot 5 which near the estuary of Yuxi River, three-year average of [SE was the maximum (5.81μmolg-1), and the minimum of [ΣSE (0.07μmolg-1) appears on spot 8 which locates in the middle of Chaohu Lake. In spot 13 the [ΣSEM]-[AVS]=3.2>2 and [ΣSEM]/[AVS]=4.45>2.34 indicate that heavy metal contaminants from Hefei city have threatened the biosafety of Chaohu Lake. (c) The spatial autocorrelation of SEMCdis weak, which indicates that spatial distribution of SEMCdis determined by anthropogenic factors rather than sediments' own attribute. Chaohu Lake has been heavily polluted by Cd from no-point source and electronic electroplating industry.

Infinite Potential Well

The classical and quantal behavior of a particle in an infinite potential well, that is periodically kicked is studied. The kicking potential is K|q|α, where q is the coordinate, while K and α are constants. Classically, it is found that for α > 2 the energy of the particle increases diffusively, for α < 2 it is bounded and for α = 2 the result depends on K. An approximate formula for the diffusion coefficient is presented and compared with numerical results. For quantum systems that are chaotic in the classical limit, diffusive growth of energy takes place for a short time and then it is suppressed by quantal effects. For the systems that are studied in this work the origin of the quantal localization in energy is related to the one of classical chaos.

Abstract BackgroundParasites infecting cats include protozoa, helminths and arthropods. Many are also transmissible to humans. Effective control relies on knowledge of parasite distribution and risk factors for infection. The present study was aimed at evaluating prevalence of major feline parasites in Italy and risk factors associated with their occurrence.MethodsOver a 12-month study period, thirteen study centers across Italy analyzed feces, hair and ectoparasites from naturally infected cats coming from feral colonies, shelters and private households. Samples from cats (n=987) were analyzed by all centers using the same diagnostic methods. Prevalence values and risk factors were evaluated statistically for identification of predictors of risk. ResultsThe overall prevalence of gastro-intestinal (GI) and bronco-pulmonary (BP) nematodes was 35.9% (354/987). T. cati was the most prevalent species (253/987; 25.6%), followed by hookworms (98/987; 9.9%). Among BP nematodes, A. abstrusus was the most common (76/987; 7.7%). Approximately 35.7% (352/987) of the study population was infested by ectoparasites. The most common were fleas 29.4% (290/987), followed by ear mites O. cynotis 9.8% (97/987).Predictors of risk for parasite infection included age, a predominantly or exclusively outdoor lifestyle, geographic area and lack of anti-parasitic treatment.ConclusionBoth ecto- and endoparasites are still common in cats throughout Italy, many of them being of zoonotic concern and vectors of pathogens to humans. Given the presence of parasites throughout the entire study period, year-round treatment should be considered. Furthermore, data confirm the need to protect the human-animal bond using proper endo- and ecto-parasiticides to reduce the risk of human infection, in application of the One-Health concept.

We used data on 64 stocks of sockeye salmon ( Oncorhynchus nerka ) from British Columbia (B.C.), Washington, and Alaska to determine whether recent decreases in abundance and productivity observed for Fraser River, B.C., sockeye have occurred more widely. We found that decreasing time trends in productivity have occurred across a large geographic area ranging from Washington, B.C., southeast Alaska, and up through the Yakutat peninsula, Alaska, but not in central and western Alaska. Furthermore, a pattern of predominantly shared trends across southern stocks and opposite trends between them and stocks from western Alaska was present in the past (1950–1985), but correlations have intensified since then. The spatial extent of declining productivity of sockeye salmon has important implications for management as well as research into potential causes of the declines. Further research should focus on mechanisms that operate at large, multiregional spatial scales, and (or) in marine areas where numerous correlated sockeye stocks overlap.

Abstract Introduction Support group for burn survivors is immensely beneficial for reintegration and normalization of the burn recovery. The corona virus pandemic, however, limited in-person interactions significantly and decreased the travel capabilities. Our regional burn center serves an 8-state region, and as such, our every other month in-person support group consisted of survivors and family members from a large geographic area. Methods Support group volunteers and staff members recognized the need for continued support of survivors during the pandemic. Limitations of large, in-person meetings were implemented by our host organization to comply with pandemic safety guidelines. Evaluation of resources available led to development of a virtually supported meeting space. Email addresses were gathered to schedule. This allowed for interaction of survivors from an unlimited geographic area. Results Support group survivor volunteers and staff met to develop parameters, topics, IT support and logistics. Every other month support group was converted to a monthly gathering virtually due to easier access by survivors. Attendees completed a survey to evaluate and make recommendations for opportunities for improvement. The same number of survivors were present for in person and virtual meetings. Conclusions During this pandemic, limitations were placed that further isolate survivors. A virtually based support group has allowed for more frequent interactions between volunteers and new survivors. Various topics were discussed including survivor preparedness for public reintegration, worker’s compensation and care giver burnout. Speakers from multiple disciplines have been able to address issues requested by survivors. In this format, we have been able to continue the support of our survivors as they continue to recover. Social distancing has isolated many people during the pandemic; virtual support group has been paramount in continuing to connect our survivor family.
