Authors: Zheng Shuai , Edwards Jonathan R , Dudeck Margaret A , Patel Prachi R , Wattenmaker Lauren , Mirza Muzna , Tejedor Sheri Chernetsky , Lemoine Kent , Benin Andrea L , Pollock Daniel A 
Published: May 2021

Background
The Centers for Disease Control and Prevention’s (CDC’s) National Healthcare Safety Network (NHSN) is the most widely used health care–associated infection (HAI) and antimicrobial use and resistance surveillance program in the United States. Over 37,000 health care facilities participate in the program and submit a large volume of surveillance data. These data are used by the facilities themselves, the CDC, and other agencies and organizations for a variety of purposes, including infection prevention, antimicrobial stewardship, and clinical quality measurement. Among the summary metrics made available by the NHSN are standardized infection ratios, which are used to identify HAI prevention needs and measure progress at the national, regional, state, and local levels.

Objective
To extend the use of geospatial methods and tools to NHSN data, and in turn to promote and inspire new uses of the rendered data for analysis and prevention purposes, we developed a web-enabled system that enables integrated visualization of HAI metrics and supporting data.

Methods
We leveraged geocoding and visualization technologies that are readily available and in current use to develop a web-enabled system designed to support visualization and interpretation of data submitted to the NHSN from geographically dispersed sites. The server–client model–based system enables users to access the application via a web browser.

Results
We integrated multiple data sets into a single-page dashboard designed to enable users to navigate across different HAI event types, choose specific health care facility or geographic locations for data displays, and scale across time units within identified periods. We launched the system for internal CDC use in January 2019.

Conclusions
CDC NHSN statisticians, data analysts, and subject matter experts identified opportunities to extend the use of geospatial methods and tools to NHSN data and provided the impetus to develop NHSNViz. The development effort proceeded iteratively, with the developer adding or enhancing functionality and including additional data sets in a series of prototype versions, each of which incorporated user feedback. The initial production version of NHSNViz provides a new geospatial analytic resource built in accordance with CDC user requirements and extensible to additional users and uses in subsequent versions.

Published: May 2021

Background
Various digital learning objects (DLOs) are available via the World Wide Web, showing the flow of clinical procedures. It is unclear to what extent these freely accessible Internet DLOs facilitate or hamper students’ acquisition of clinical competence.

Objective
This study aimed to understand the experience of undergraduate students across clinical disciplines—medicine, dentistry, and nursing—in using openly accessible Internet DLOs, and to investigate the role of Internet DLOs in facilitating their clinical learning.

Methods
Mid-year and final-year groups were selected from each undergraduate clinical degree program of the University of Hong Kong—Bachelor of Medicine and Bachelor of Surgery (MBBS), Bachelor of Dental Surgery (BDS), and Bachelor of Nursing (BNurs). All students were invited to complete a questionnaire on their personal and educational backgrounds, and their experiences and views on using Internet DLOs in learning clinical procedures. The questionnaire design was informed by the findings of six focus groups.

Results
Among 439 respondents, 97.5% (428/439) learned a variety of clinical procedures through Internet DLOs. Most nursing students (107/122, 87.7%) learned preventive measures through Internet DLOs, with a lower percentage of medical students (99/215, 46.0%) and dental students (43/96, 45%) having learned them this way (both P<.001). Three-quarters (341/439, 77.7%) of students accessed DLOs through public search engines, whereas 93.2% (409/439) accessed them by watching YouTube videos. Students often shared DLOs with classmates (277/435, 63.7%), but rarely discussed them with teachers (54/436, 12.4%). The accuracy, usefulness, and importance of Internet DLOs were rated as 6.85 (SD 1.48), 7.27 (SD 1.53), and 7.13 (SD 1.72), respectively, out of a high score of 10.

Conclusions
Self-exploration of DLOs in the unrestricted Internet environment is extremely common among current e-generation learners and was regarded by students across clinical faculties as an important supplement to their formal learning in the planned curriculum. This trend calls for a transformation of the educator’s role from dispensing knowledge to guidance and support.

Published: May 2021

The distribution range of Jaguar (Panthera onca) is being reduced due to multi-scale habitat conversion, intensive hunting, illegal trafficking, habitat fragmentation, and the construction of highways and other infrastructure. Because of the decrease in population, this species’ listing has changed from vulnerable to a threatened category. Due to the ecological importance of this species, organizations like Red Colombiana de Seguimiento de Fauna Atropellada have proposed the establishment of wildlife corridors. But little is known as to recognize the driving forces in these habitat changes and where these corridors should be established. To address this lack of information, we determined the spatial extent to which the current distribution and access to P. onca habitat is being driven by deforestation, armed conflict, agriculture expansion, urbanization and the construction of highways in the Bajo Magdalena area of Colombia. We then identified potential areas for proposing conservation corridors. To do this, we used available geospatial information on P. onca distribution in the Corporación Autónoma Regional areas in the municipalities of Puerto Salgar, Caparrapí and Guaduas, as well as transportation network, administrative unit, and deforestation data from 2010 to 2018. We also calculated habitat distances to population centers and the distribution of P. onca relative to roads. Our findings suggest that urban population and highways affect 83 % of the total area of its distribution; deforestation increased by 47.9 km2 in the 105.24 km2 study area with 5.6 km2 alone left as P. onca habitat. We concluded that conservation initiatives must be implemented inside P. onca’s distributional range and buffer zones. Urbanization and the construction of highways were highly influential variables associated with the loss of P. onca habitat. Further, we propose that precautions along the principal road that connects Puerto Salgar and Guaduas should be taken into consideration to maintain the genetic flow and movement of the P. onca population as it affects 87 km of this proposed corridor.

Published: May 2021

Since its founding in 2008, Bitcoin (financial code: BTC) has emerged as a digital currency in market cap and continues to attract investors and policymakers' attention. In recent years, BTC has high price volatility, a substantial increase in 2016, followed by a significant decline in 2018. Unlike stock markets, BTC is open for 24x7 dan has no closing period. It means everyone can trade it for any time. However, this flexibility carries investment risk. This research attempts to forecast BTC's price by considering the blockchain's information to minimize the risk. We employ Long-Short Term Memory (LSTM), the artificial Recurrent Neural Network (RNN) architecture. Its model can avoid long-term problems. The data used is BTC's price and blockchain information data from August 4, 2018, to January 21, 2020. The model with 20 neurons and 500 epochs has the smallest MSE value. Then a prediction has an accuracy rate of 91.07%.

This article is devoted to the conceptual analysis of the dialectical method for understanding social change in the philosophy of global constitutionalism. The purpose of the research: from the position of socio-philosophical methods of cognition of social reality and ideas reflecting it, to analyze the dialectic model in the doctrine of social changes in the philosophy of global constitutionalism. An analysis of the dialectical method as a theory for understanding social change in the philosophical concept of global constitutionalism has shown that: in the process of its formation, the Hegelian concept of dialectical development and the dialectical materialism of the Marxist-Leninist type, including its basic laws; it is aimed at developing a system of arguments to justify the natural evolutionary nature of the origin of the world capitalist system; the process of removing the qualitatively heterogeneous opposites accumulated in the process of social development is also subordinate to the general logic of the development of the world capitalist system.

Two Suns? Data, Algorithms, Spaces and Techno Feudalism
Authors: Cleave Peter 
Published: May 2021

A main thread in the Two Suns? series might be summed up as follows. There are several spaces or forms of space involved; territorial space, outer space, cyberspace and living space, And there is data to be found and owned in each of these spaces. That data may be processed using algorithms in each space and across all spaces. With such a thread in mind one argument in the Two Suns? series so far and going forward is as Data, Algorithms, Spaces, and Techno Feudalism follows; we should treat Big Tech as an incipient state with its own entry and exit points and its own infrastructure rather than constantly framing discussion in terms of a nation-state like the USA. The latter may have been and may still be a host for the Algorithmic State but this is not necessarily ongoing. Furthermore there is a range of nation states from the strong to the barely formed ranging through, say the examples of the USA, Australia and Myanmar and a varying use and influence of the algorithm within these nation states.

Published: May 2021

Indonesia is one of the largest culinary attractions in Southeast Asia. The culinary diversity in Indonesia encourages stakeholders to create restaurant businesses with effective and efficient business processes. One of the efforts to make the restaurant business process effective and efficient is to build a restaurant management information system. By using a system, business actors will be able to control and evaluate their business with appropriate reports. For this reason, the purpose of this study is to build a restaurant management information system using the RAD (Rapid Application Development) method, because building this application requires a systematic, structured, and object-oriented process. The RAD method emphasizes a high quality systems, fast development and delivery and low costs development process [1] so that this process requires a serious role from business actors to build a restaurant management information system. The results of this system design can make it easier for business actors to control the business process from the customer to the kitchen so that the food and beverage ordering process will be served quickly. The GUI restaurant management information system is made interactively so that customers and business actors can easily understand the system. The test results of this system use black-box testing, with the conclusion that the system is successful to run.
Examining Socio-Demographic Factors in Workplace Deviance among Selected University Workers
Authors: Olasupo Matthew O. , Fagbenro Dare A. 
Published: May 2021

Abstract

Introduction: Despite studies on workplace deviance globally and in an emerging country like Nigeria, the role of socio-demographic factors on dimensions and overall workplace deviance have been largely neglected in the literature. This lacuna hopes to be filled by this present study through examining the role of socio-demographic factors (gender, staff category and university type) on dimensions and overall deviance among university workers in Southwest, Nigeria.

Methods: The study adopted a cross-sectional survey design and a sample size of 384 university workers whose ages range from 22 to 63 years with a mean of 46.88 (SD=9.36) were conveniently selected from four universities. Data were sourced through the Workplace Deviant Behaviour scale and selected demographics which was analyzed using t-test for independent samples.

Results: The results found that there was no gender difference in workplace deviance among university staff [t(382)=-0.37, p>.05]. The study also found that academic workers have a higher tendency to engage in workplace deviance than their non-academic counterparts [t(382)=2.38, p<.05]. Finally, workers from private institutions reported significantly higher workplace deviance than workers from public universities [t(382)= -2.20, p<.05].

Discussion: We can deduce from the study that gender did not have any influence on work deviance as reported by previous study. Also academic staff has higher work deviance than non-academic staff which could be as a result of academic autonomy. Also, staff from private university has higher work deviance than public university which could be as result of the poor job security of private university in Nigeria.

Limitations: One limitation of the study is that some respondents might fake their responses and not disclose their true feeling about the subject matter.

Conclusion: Based on these findings, we concluded that there was no gender difference on work deviance, also there was staff category difference on work deviance and finally, employee from private universities exhibited higher work deviance than their counterpart from public universities.
Share of road transport in greenhouse gas emissions in Poland in 1988–2015

Published: May 2021

Abstract
The results of an analysis of the greenhouse gas (GHG) emission inventory in Poland in the years 1988–2015 are presented, paying special attention to the impact of road transport on the intensification of greenhouse effect. The analysis was made based on the official results compiled by the National Centre for Emissions Management and Balancing (KOBiZE) at the Institute of Environmental Protection – National Research Institute.
It was found that carbon dioxide emission represented the dominant part of the total GHG emissions, despite that there were other gases having far greater greenhouse effect potential. There was a general downward trend for the national annual emission of basic GHGs. The estimated share of road transport in the GHGs emission was not high: from 4% in 1988 to around 12% in 2015.
For motor vehicles, there is a dominant share in the GHGs emissions of passenger cars: (50 ÷ 60)%.
In the years 1988–2015, there was a relative decrease by about 32% in the national annual emission of carbon dioxide equivalent from all sources covered by the inventory. That notwithstanding, the national annual emission of carbon dioxide equivalent arising from transportation increased generally by about 93% and that from the road transport increased by as much as 117%. The increase in GHGs emissions from motor vehicles resulted mainly from a significant growth in car numbers. Technical progress in the construction of motor vehicles can be evaluated by considering the average annual emission of carbon dioxide equivalent from a conventional car, which has been decreasing since 1998.

Published: May 2021

Abstract
The aim of the investigation was to assess the utility of spruce needles as a potential material to be used for monitoring the contamination level of the environment of Tricity agglomeration (represented by Gdansk and Gdynia). This aim was realized by determining the levels of selected essential elements indispensable for the life of living organisms, such as Fe, Zn, Mn and Cu, as well as toxic, namely Cd and Pb, in spruce needles collected in the locations in Gdynia and for comparison, in Gdańsk. Due to this, the collected samples of needles were dried, and next digested by microwave technique in order to prepare them for quantitative analysis by atomic absorption spectrometry. Moreover, the same metallic elements were determined in the soil samples collected under the spruces, from which needles were taken for the investigation. The concentrations of the studied elements were found in the range of mg/kg of dry mass in the following order: Fe, Mn, Zn, Pb, Cu and Cd (needles), and Fe, Mn, Cu, Zn, Pb and Cd (soils). By application of statistical methods (correlation, variance and principal component analyses), the differences in the elemental composition of spruce needles were identified, as well as sources of this differentiation.

Abstract
In Poland and most of the areas of Europe, the beech, that is, Fagus sylvatica L. is one of the most vital species found in the species composition of forests. A number of the species of foliophages tend to develop on the leaves, which may contribute to the dieback of the tree. The demonstrated results are the effects of the research conducted in 2018 in the Cisów-Orłowiny Landscape Park. Subsequently, 11 species of foliophages were initially discovered there. Such species were inclined to form galls and the miner damages to the beech leaves. Among 4,000 of the analysed leaves, 398 galls and 498 leaf miner damages were found. They were caused by the representatives of insects and mites.
