Authors: Fernández-Pascual Rosaura , Marín Jiménez Ana , Pilar Fernández- Sánchez María 
Published: January 2022

This paper explores how to incorporate information visualization tools into qualitative studies to represent the underlying structure of knowledge. Information visualization plays a key role in many areas such as decision-making, data mining, market studies, or knowledge management. A case of experiential learning was developed for Quantitative Techniques in Business and Administration and Economy Degrees at the University of Granada, Spain. The goal is to analyze the opinion of students (n = 227) on the development of the activity through information visualization techniques. The gathered information was subjected to a categorization process to unify and homogenize the responses. After a term-clumping process, a co-word analysis using the VosViewer software is used to analyze the relationships among terms and provide the network maps. Results display the main associations and clusters of terms used when assessing the experiential activity, using qualitative techniques. In conclusion, the strengths of data visualization enabling a better understanding of data for qualitative studies are established.

Authors: Ploch Jindřich , Palatková Monika 
Published: January 2022

Tourism and air transport are among the sectors most affected by the Covid-19 crisis. The pandemic lasting more than a year is reflected in short-term effects in both sectors, but there are also severe long-term consequences. National authorities will have to set recovery plans following the relevant policies and encompass international cooperation with public and private entities. The article aims to identify the methods and procedures that can be implemented, which can mitigate the consequences of the crisis and initiate the renewal of international tourism and air transport in particular. The paper's methodology is based on current statistical data and strategic documents at the national and international level represented by the international organizations (esp. UNWTO, WTTC, IATA, ICAO, ECAC). The focus is on the crisis management of the public sector entities in terms of the definition and implementation of reconstruction strategies, on private sector stakeholders, on the interconnection of the tourism and the air transport sectors, and cooperation in the international environment. Methods and tools for the renewal of both sectors are based on a strategic approach of the public sector, support for the introduction of new business models in the private sector, change in the product and marketing mix, digitization, innovation, and education.

The Impact of Participation in Service Company’s Socially Responsible Activities on Employee’s Affective Commitment
Authors: Damnjanović Milena 
Published: January 2022

Employees’ perspectives of the company’s social responsibility (SR) and the company’s SR impact on employees have so far been given little attention in research. This gap is surprising since it is well known to what extent employees affect overall companies’ results. They have a crucial role in SR activities implementation, so it is important for management to define employees’ roles in SR activities implementation carefully. This paper explored the influence of employees’ participation in SR activities on their affective commitment to service companies. The main hypothesis was that participation in SR activities has a significant positive impact on employees’ affective commitment. The goal was to show that employees who participated in SR activities were more committed than employees who did not participate in SR activities. The data were collected through a questionnaire and analysed using descriptive statistics, independent-samples t-tests, and one-way ANOVA. The results showed that there were no statistically significant differences in the level of affective commitment between employees who participated in SR activities and those who did not participate in them. Less than half of respondents participated in SR activities, so a suggestion for managers was to share the positive experience of participation in SR activities and invite employees to participate more.

Authors: Pollozhani Alba , Hadzimustafa Shenaj 
Published: January 2022

This study aims to analyse how the monetary policies of the Republic of North Macedonia and the Republic of Albania, as one of the two critical macroeconomic policies, have reacted in response to COVID-19 for the year 2020. Last year, the year 2020, the pandemic caused these two countries to react through monetary policy. This research examines how central banks of both countries have changed traditional monetary policy tools for tackling the pandemic, starting with open market operations, required reserve ratio, the overnight loans interest rate, and the available deposits interest rate. The research continues with analyzing whether they were used and what non-traditional tools were applied in that period. The study analysis concludes which monetary policies have been pursued in the Republic of North Macedonia and the Republic of Albania, whether there have been non-traditional tools and how the scope for interbank interest rate volatility has changed. Our study revealed that both countries had pursued an expansive monetary policy, there were also non-traditional tools, and the scope for interbank interest rate volatility has shifted towards narrowing.

Published: January 2022

From the beginning of 2020, the whole world has been shaken by a contagious disease called Covid-19, its actual name being SARS-CoV-2. It first appeared in China, in Wuhan, Hubei Province, in December 2019, and the World Health Organization (WHO) was informed about it on the 31st of December 2019. On the 11th of March, 2020, WHO declared the Covid-19 outbreak a pandemic, and no country has been able to contain this coronavirus. This medical or health crisis evolved into a pandemic and led to a global economic crisis. This study investigates the wealth effect of the coronavirus pandemic announcement on the Information Technology Industry companies in Europe. We apply the classical event study methodology. Our sample contained 87 companies. The results show a strong negative reaction of information technology companies upon this announcement. The European investors perceived this announcement as a negative signal that will disturb the lives of everyone and will create economic instabilities and havoc in all sectors of an economy.

Diffuse Runoff from Agricultural Lands within a River Basin and Water Protection Measures
Authors: V. Kireicheva Liudmila , M. Yashin Valery , А. Lentyaeva Ekaterina , D. Timoshkin Aleksey 
Published: January 2022

This paper is dedicated to the study of the pollutants coming from agricultural lands located within the catchment into the Yakhroma river, a third-order tributary of the Upper Volga. The area of the river catchment is 1437 km2. It is located in the north-eastern part of the Moscow region, which geographically belongs to the Klinsko-Dmitrov ridge (the upper part of the basin) and the Upper Volga Lowland. The slopes and floodplain included in the reclaimed lands (more than 9 th ha) are lined with cities, rural settlements, numerous kitchen gardens, and agricultural lands. Water quality, river profile from the source to the mouth, and sources of pollution within the reclaimed lands of the Yakhroma floodplain were studied from 2004 to the present. A geospatial intelligence system (GIS) was developed for the catchment area. Land areas are allocated according to the conditions of surface runoff formation, taking into account soil types and slopes. The studies of the river water quality, tributaries, and drainage network in the reclaimed lands showed biogenic pollution caused by insufficiently treated wastewater discharged from cities and agricultural land, especially within the reclaimed massif. The calculations of the removal of nitrogen, phosphorus, and potassium from surface and drainage waters revealed that the main role in the pollution of both surface and drainage waters is played by nitrogen and potassium compounds, and to a lesser extent by phosphorus compounds. For nitrogen, removal from surface runoff was 27.36 t/year; for phosphorus it was 6.06 t/year; for potassium it was 242.28 t/year; with drainage runoff, the removal of nitrogen was 98.88 t/year; the removal of phosphorus was 0.38 t/year; the removal of potassium was 37.04 t/year. To reduce the inflow of surface diffuse runoff and to purify collector and drainage waters from nitrogen and phosphorus compounds, including the creation of bioplateaus and biosorption structures, it was proposed to use a set of protective measures, which will significantly reduce the biogenic load on the river flow.
Response of Marine Plankton Communities in Ponds to the Presence of Vertical Structures
Authors: Emília Cunha Maria , Quental Ferreira Hugo , Barradas Ana , Pousão-Ferreira Pedro 
Published: January 2022

The effects of bottom vertical structures like AquaMats® in enhancing plankton productivity was evaluated. One experimental earthen pond of 500 m2 was provided with AquaMats® increasing the surface substrate area 12 times and water quality, phytoplankton and zooplankton populations developed during almost 100 days was compared with a pond without AquaMats®. Their presence favored the development of Dinoflagellates (Miozoa, Dinophyceae), mostly Gymnodiniales, which may be of some concern since some species of this group have been associated with toxic algal blooms while in the ponds without AquaMats® Diatoms (Bacillariophyta) predominate. In both ponds plankton production was very much sculptured by external nutrients added to the systems. The balance between different nutrients is extremely important to regulate the phytoplankton populations with Diatoms blooming at silicate concentrations higher than 2 μM and below this level and at low nitrate and high ammonium being more appropriate for Dinoflagellates. The linkage between phytoplankton and zooplankton population in ponds is strong with zooplankton exerting control over the phytoplankton population and vice-versa. The use of vertical substrates enhances plankton productivity by increasing the substrate area for periphyton fixation. The main zooplankton taxonomic groups associated with the presence of AquaMats® were Calanoid and Harpacticoid copepodites and nauplii, veligers of gastropods and trochophore of polychaets, larval stages of organisms that except for calanoid copepods are benthic and correspond to the meroplanktonic phase in the life cycle of those organisms.
Child perception and parent’s perception about child sleep quality
Authors: Gomes Ana Maria , Martins Mariana Costa 
Published: January 2022

Introduction Sleep is a physiological necessity that interferes with the activity during the day. This study aimed to analyze child perception about sleep quality and compare it with parent’s perception about the quality of their children’s sleep, and to investigate the sleep quality of Portuguese schoolchildren. Analyze the differences between the sexes and the type of school attended.
Material and Methods Cross-sectional study, quantitative methodology. The results of two questionnaires, the Pittsburgh sleep quality index (PSQI) answered directly by the children, and the children’s sleep habits questionnaire (CSHQ), answered by the parents of 883 children, were analyzed and compared.
Results PSQI reveals good sleep quality, which contradicts the results of CSHQ. The CSHQ indicates a mean sleep deterioration index (IPS) value of 46.12 (above the cutoff point, 44) indicating that on average the children in this sample have poor sleep quality. There is no significant difference between girls and boys regarding IPS. There is a significant difference in the level of daytime drowsiness (p=.018), girls wake up moodier (p=.011), have more difficulty getting out of bed in the morning (p=.019), and take longer to fully awaken than boys (p=.004).
Conclusion The data show that children seem to have poor sleep quality and that they erroneously evaluate it, but these same data should be read with caution since the reason for the different perception between parents and children is not known.

Published: January 2022

Introduction Problematic over usage of smartphones has led to various deteriorating effects including poor sleep quality. Screen exposure, especially near bedtime, directly leads to poor sleep quality. We aimed to measure smartphone screen-time (ST) statistics of the participants directly using a smartphone application. Furthermore, we aimed to assess sleep quality using the Pittsburgh sleep quality index (PSQI), and to investigate the association between ST & PSQI.
Material and Methods This descriptive cohort study was conducted among 280 students of MBBS at Rawalpindi Medical University for a period of 1 month (30 days). Physically healthy students who owned Android smartphones were included in the study. Students with diagnosed sleep disorders and students taking sleep medication were excluded from the study. ST was recorded using a smartphone application. Sleep quality was assessed at the end of 30 days using the PSQI questionnaire. Data entry and analysis was done using SPSS v23.0.
Results Total and mean ST were calculated for every participant. The mean screen time of 242 individuals was 147.50±51.09 hours. The mean PSQI score was 6.68±2.3. 65.70% of the participants had a poor sleep quality (PSQI>5). Pearson’s correlation revealed that long total ST was associated with decreased sleep quality (R=0.356, p<0.001).
Conclusion Our findings are in accordance with previous scientific literature largely based on self-reported ST measurements and affirm that excessive ST deteriorates sleep quality and hence has numerous adverse physical and psychological manifestations.

Published: January 2022

Background
On January 8, 2020, the Centers for Disease Control and Prevention officially announced a new virus in Wuhan, China. The first novel coronavirus (COVID-19) case was discovered on December 1, 2019, implying that the disease was spreading quietly and quickly in the community before reaching the rest of the world. To deal with the virus’ wide spread, countries have deployed contact tracing mobile applications to control viral transmission. Such applications collect users’ information and inform them if they were in contact with an individual diagnosed with COVID-19. However, these applications might have affected human rights by breaching users’ privacy.

Methodology
This systematic literature review followed a comprehensive methodology to highlight current research discussing such privacy issues. First, it used a search strategy to obtain 808 relevant papers published in 2020 from well-established digital libraries. Second, inclusion/exclusion criteria and the snowballing technique were applied to produce more comprehensive results. Finally, by the application of a quality assessment procedure, 40 studies were chosen.

Results
This review highlights privacy issues, discusses centralized and decentralized models and the different technologies affecting users’ privacy, and identifies solutions to improve data privacy from three perspectives: public, law, and health considerations.

Conclusions
Governments need to address the privacy issues related to contact tracing apps. This can be done through enforcing special policies to guarantee users privacy. Additionally, it is important to be transparent and let users know what data is being collected and how it is being used.

Background
The disease burden from ischaemic heart disease remains heavy in the Chinese population. Traditional risk scores for estimating long-term mortality in patients with acute myocardial infarction (AMI) have been developed without sufficiently considering advances in interventional procedures and medication. The goal of this study was to develop a risk score comprising clinical parameters and intervention advances at hospital admission to assess 5-year mortality in AMI patients in a Chinese population.

Methods
We performed a retrospective observational study on 2,722 AMI patients between January 2013 and December 2017. Of these patients, 1,471 patients from Changsha city, Hunan Province, China were assigned to the development cohort, and 1,251 patients from Xiangtan city, Hunan Province, China, were assigned to the validation cohort. Forty-five candidate variables assessed at admission were screened using least absolute shrinkage and selection operator, stepwise backward regression, and Cox regression methods to construct the C2ABS2-GLPK score, which was graded and stratified using a nomogram and X-tile. The score was internally and externally validated. The C-statistic and Hosmer-Lemeshow test were used to assess discrimination and calibration, respectively.

Results
From the 45 candidate variables obtained at admission, 10 potential predictors, namely, including Creatinine, experience of Cardiac arrest, Age, N-terminal Pro-Brain Natriuretic Peptide, a history of Stroke, Statins therapy, fasting blood Glucose, Left ventricular end-diastolic diameter, Percutaneous coronary intervention and Killip classification were identified as having a close association with 5-year mortality in patients with AMI and collectively termed the C2ABS2-GLPK score. The score had good discrimination (C-statistic = 0.811, 95% confidence intervals (CI) [0.786–0.836]) and calibration (calibration slope = 0.988) in the development cohort. In the external validation cohort, the score performed well in both discrimination (C-statistic = 0.787, 95% CI [0.756–0.818]) and calibration (calibration slope = 0.976). The patients were stratified into low- (≤148), medium- (149 to 218) and high-risk (≥219) categories according to the C2ABS2-GLPK score. The predictive performance of the score was also validated in all subpopulations of both cohorts.

Conclusion
The C2ABS2-GLPK score is a Chinese population-based risk assessment tool to predict 5-year mortality in AMI patients based on 10 variables that are routinely assessed at admission. This score can assist physicians in stratifying high-risk patients and optimizing emergency medical interventions to improve long-term survival in patients with AMI.

Authors: Bishop B. , Abang F. B. P. , Attah S. 
Published: January 2022

Aims: The study was conducted to evaluate the effect of inclusion of Prosopis seed coat fermented with rumen content at different levels as energy source on the serum biochemical composition and heamatological indices of broiler chickens.
Study Design:Data collected were subjected to analysis of variance in a completely randomized design.
Place and Duration of Study: The study was conducted at the Livestock Teaching and Research Farm of the University of Agriculture Makurdi, Benue State, Nigeria. Between November 2016 and January 2017.
Methodology: The study was in two phases; the starter and finisher phase, in each of the phases, there were five dietary groups and fermented Prosopis africana seed coat meal (FPASCM) was included at 0, 10, 15, 20 and 25% to replace maize. The total of two hundred and sixty (260), day- old Zartech broiler chicks were randomly distributed to five dietary treatments with four replicates of 52 chickens per treatment and each replicate had 13 birds. The birds were raised on deep litter and fed ad-libitum and drinking water provided daily and performance was monitored. At the end of the eight week, blood was collected via the wing web for serum and haematological assay.
Results: The results of haematological parameters of broiler chickens fed varying levels of fermented Prosopis africana seed coat are presented in Table 3.There were no significant (P>0.05) differences between treatments for parameters measured except for PCV and haemogobin. The PCV values ranged from 25.00 -28.25% and haemoglobin values ranged from 8.35 -9.40g/dl. It was observed that most of the haematological indices measured fell within the normal reference range values. The results of serum biochemical assay revealed that serum glucose 45.85-107.22 mg/dl varied significantly (P<0.05) among the dietary treatments. Birds served 25% FPSCM had the highest value while those served 15% FPASCM recorded least value.
Conclusion: Based on the observations from this study, it was concluded that FPASCM could be included in the diets of broiler chickens up to 25% without compromising the health of the birds.
