Introduction. The ambiguous attitude of professionals in the field of education, students and their parents to modernization based on ICT, differences of regional educational systems in their provision with digital tools have heightened the need for research on the relevant problem associated with the implementation of the federal project called “Digital School”. The purpose of this study is to analyze the vectors of the impact of digital learning technologies on functional and psychophysiological state of students' organisms. Materials and Methods. The authors have conducted a theoretical analysis of normative and legislative documents, the latest scholarly publications on the stated problem, mainly for the recent three years, using the methods of analogy, comparison, generalization and concretization. Results. The article summarizes the contradictory results of empirical studies confirming both positive and negative effects of digital educational gadgets that differ in technology and context on psychophysiological and somatic parameters of health and learning performance. The authors emphasize the idea that the positive vector of the “digital” school can dominate over the negative one only in those educational settings where the teaching staff creates a learning environment aimed at maintaining hygienic safety of children's life. A prerequisite for this is professional development of teachers who are ready to work in a digital environment. Conclusions. “School” gadgets are innovative tools, the adequate use of which contributes to improving the quality of education, without a negative impact on the psychological comfort and psychosomatic health of students.

The Impact

Twitter has gained attention in recent years as a tool to use in higher education to enhance students’ learning, engagement, and reflective writing. This study explored public health students’ perceptions on the usefulness of Twitter as a learning tool, engagement with their peers, staff, and the broader public health community. Participants were Master of Public Health students from a public university based in Sydney, Australia. A mixed methods approach was used combining content analysis of tweets, an online survey and two focus groups. Students were asked to engage with Twitter by reflecting on each week’s teaching content and by liking and replying to their peers’ tweets. Participation and engagement in this task were high initially and declined toward the end of semester. Most student tweets aligned with topics taught during the semester. Survey and focus group data indicated most students had positive views on using Twitter and reported finding engagement with Twitter beneficial in obtaining current information on health promotion news and trends, increasing their professional networks and allowing them to connect with their peers and teaching staff. Results indicate Twitter is a promising interactive approach to enhance public health students’ engagement and overall learning experience, as well as being useful for professional networking. Larger scale empirical studies are needed to investigate the impact of the use of social media platforms such as Twitter to various learning outcomes longitudinally and beyond this course.

AbstractThe 2011 National Nutrition Survey of Pakistan revealed that 51% of the country’s population was consuming less than 2,100 calories a day. In the backdrop of rising food insecurity, hunger, and malnutrition in Pakistan, this study aims to measure the effects of indirect taxation on health outcomes of children (<5 years). More specifically, the impact of the incidence of General Sales Tax (GST) in the province of Punjab has been estimated on a child’s height and weight. The proponents of the uniform GST argue that the tax would not affect children because most food items consumed by children are exempted from the GST. However, the opponents believe that households, especially those belonging to the lower-income group, would reallocate resources away from children in the face of higher GST. To study these effects, we utilized three different waves (2007–08, 2011 & 2014) of Multiple Indicators Cluster Surveys (MICS). The results show that the tax incidence, and not the GST rate, has a significantly negative impact on children’s height-for-age Z-score (HAZ). No effect was found on the weight-for-age-z-score (WAZ). These results are robust to different specifications and exhibit considerable heterogeneity across different income groups. These findings suggest that the exemption of certain food items for children from the GST may not eliminate the negative effects of this tax on a child’s health. Thus, our study raises concerns about the long term welfare consequences of GST.

The Impact

This paper provides the first estimates of the net impact of CETA participation on the components of CETA participants' post-program earnings. Employing a sample of 1975 CETA enrollees and comparison groups drawn from the March 1978 CPS using a nearest-neighbor matching technique, the authors estimate statistically significant negative effects on men's earnings and statistically significant positive effects on women's earnings. These results stem partly from the impact of CETA participation on the likelihood of being employed after leaving the program (negative for men, positive for women), but also from a negative impact on hours worked during the year and hourly wage rate for men and a large positive impact on hours worked per week and weeks worked per year for women.

The paper describes a series of effects created by the impact of environmental factors on artworks in museums, as well as the way that active monitoring of these destructive agents (temperature and relative humidity) is done. Over time, artefacts exhibited within museums are subject to a series of degradations caused by external factors (air components, humidity, temperature, sunlight, bacteria, molds or fungi etc.), which can leave a negative impact on these goods with cultural value. The main observed negative effects are directly and intimate related to the deterioration of wood sculptures by the occurrence of cracks and the installation of different types of bacteria; the appearance of brownish-red spots on the surface of the paper and the increase in its reliability; various types of corrosion of artworks from different metals; color losses and cracks on paintings etc. The study brings to the fore the damaging effects produced on the different cultural works hosted within the County Art Museum - Art Center Baia Mare.

The Impact

The purpose of the academic paper lies in assessing the state of income, expenditure and savings of households under conditions of pandemic instability. The research methodology is based on the statistical analysis of data on income, resources and savings of households in Ukraine for 2010-2020. The scientific novelty involves identifying the positive and negative effects of the pandemic on the household economy. Conclusions. The positive and negative effects of the impact of spreading the pandemic on the household economy have been revealed in the research, and as a result, the decline in economic activity and the growth of unemployment in Ukraine. It has been determined that in the period of 2020 pandemic, costs decreased by 2% and resources increased by 3%. In 2020, the share of expenditures on food and non-alcoholic beverages increased from 46,6% to 48,1% in 2019, and on non-food goods and services - decreased from 41,5% to 39,8%. The population with per capita equivalent total income per month, below the actual subsistence level, was 8,9 million people in 2019 (23,1%), in 2020 – 8,8 million people (23,2%). Despite experts’ assessments of the likely increase in poverty as a result of COVID-19 spreading under two scenarios (according to the absolute criterion, it will increase from 27,2 to 43,6%; according to an absolute criterion, it will increase from 27,2 to 50,8%). It can be noted that the COVID-19 pandemic has had a negative impact on the poorest sections of the population with low incomes. It has been determined that in the context of social-economic impact of COVID-19, families who find it more difficult to diversify their own incomes are the most vulnerable ones. The following categories have been most affected by the pandemic (they will have had the largest increase in poverty compared to the baseline scenario), namely: households with three or more children; single parents with children; households with children under three; single retirees over 65 years.Along with this, thanks to the monetary policy that has ensured a stable level of inflation and return on deposits, the share of household deposits has increased the most in the last ten years to 27%. However, it is worth noting that quarantine and the COVID-19 pandemic have led to a trend towards a partial flow of population resources from time deposits to card and savings accounts. After all, citizens sought to have free money in case of unforeseen expenses due to the uncertainty of the future development of events. Key words: households, income, resources, consumer expenditures, economic crisis, pandemic instability, quarantine restrictions.

The Impact

There is a consensus that corruption may result in high societal costs. A growing body of research reveals the negative effects of corruption on a variety of economic indicators. This chapter presents a literature review on the impact of corruption on entrepreneurship. It allows us to suggest that one of the transition channels through which corruption has impacted growth is entrepreneurship. The main channels in which corruption impacts entrepreneurship is through reduced incentives for entrepreneurial activity and reduced trust within the system. The authors present evidence that the negative impact of an incremental increase in the level of corruption on entrepreneurship is more harmful in developed countries than in developing countries. Thus, they stress the need for more research in this area with the aim of establishing appropriate frameworks for the fight of corruption in both developing and developed countries and suggest significant gains from anti-corruption efforts, especially in developed countries.

The Impact

Most studies on reusable digital learning materials, Learning Objects (LOs), relate to their use in universities. Few empirical studies exist to explore the impact of LOs on pedagogy, especially in schools. This chapter provides evidence from an evaluation of the use of LOs in schools. The evidence is from an EU-funded project Context E-Learning with Broadband Technologies, involving 500 schools in six countries across Europe, to examine the impact of LOs on pedagogy. It brought together producers and users to try out technically and pedagogically sound ways of producing, making available through a portal, and using LOs. This chapter reports data from both quantitative and qualitative studies conducted during 2004, including: online surveys (of all the teachers involved), routine data from the portal, semistructured interviews in 40 schools in all six countries, experimental studies in one of these countries, and 13 classroom case studies in four of the countries.

The Impact

The study of vulnerability constitutes a central axis in research work on sustainability. Social vulnerability (SV) analyzes differences in human capacity to prepare, respond and recover from the impact of a natural hazard. Although disasters threaten all the people who suffer from them, they do not affect all members of society in the same way. Social and economic inequalities make certain groups more vulnerable. Factors such as age, sex, social class and ethnic identity increase vulnerability to a natural disaster. Ten years after the earthquake in Haiti in 2010, this work deepens the relationship between natural disasters, SV and gender, exploring the unequal distribution of the SV in the face of a seismic risk. The source of statistical information has been obtained from the Demographic and Health Survey (DHS), developed by the United States Agency for International Development (USAID). Multicriteria decision techniques (TOPSIS) and the differences in differences (DID) technique are used to analyze variations in gender inequality in SV as a result of the catastrophic event. The results obtained reinforce the idea of the negative impact of the disaster on the SV. Additionally, an intensification of the negative effects is observed when the household is headed by a woman, increasing the gap in SV between households headed by women and the rest of the households. The conclusions obtained show additional evidence of the negative effects caused by natural disasters on women, and important implications for disaster risk management are derived that should not be ignored.

Purpose The purpose of this paper is to review several influential empirical studies that examine the performance of state-owned enterprises (SOEs). The paper undertakes a citation analysis of journals, authors and titles in the area of privatization and firm performance in general, and assesses the impact of privatization on the performance of SOEs in particular. Design/methodology/approach The methodology is based on a systematic and structured review of over 100 papers published in economics, public management, business strategy and related social sciences. The systematic review is based on citation analysis of journals, authors and titles. The journal and author citation counts were tabulated by leveraging the databases of SCImago Journal Rankings and Google Scholar and filtered it to find out the most highly cited journals and authors. The structured review is based on the framing opinion with respect to major findings, variables selected, measurement techniques and statistical tools applied by different researchers. The impact is measured through coding a value “P” in case of positive effects, “N” in case of negative effects and “NT” in case the study found both positive and negative effects. Findings The citation analysis reveals that American Economic Review, Journal of Financial Economics, Review of Financial Studies and Journal of Finance as the top-cited journals, and Megginson and Netter (3,468), Megginson et al. (1,737), Djankov and Murrell (1,356), Boardman and Vining (1,320), Balsam et al. (1,094) and DeWenter and Malatesta (1,018) as the top-cited authors in this particular research field. While majority research studies have revealed a significant improvement in the performance of SOEs in the post-privatization period, few studies have reserved their impact as neutral or even negative in some respects. Originality/value Given that economic transitions, corporate governance, and performance of SOEs have attracted a great attention from public management and business strategy scholars in recent years, this paper aims to summarize a large number of empirical studies that examine the performance of SOEs. The paper would be useful to future researchers especially the beginners and early career researchers in terms of its current trends, selection of variables, measurement techniques and statistical tools applied.

Abstract Only few studies in the plant tissue culture literature have examined the impact of filter paper on in vitro plant organogenesis. In this study, using a model plant, hybrid Cymbidium Twilight Moon ‘Day Light’, the impact of a single or double layer of Advantec #2 or Whatman #1 filter paper on new protocorm-like body (neo-PLB) formation on Teixeira Cymbidium (TC) medium was examined for half-PLBs (transgenic and non-transgenic), PLB-derived transverse thin cell layers (tTCLs), and PLB synseeds. In addition, the response of half-PLBs or tTCLs to two antibiotics (kanamycin and cefotaxime, commonly used in plant genetic transformation studies) was investigated either directly on gelled medium or on filter paper-overlaid medium. Filter paper negatively affected most growth and developmental parameters of all the explants tested, both transgenic and non-transgenic. A double sheet of filter paper had a significantly (P ≤ 0.05) more negative impact than a single sheet, relative to the control values (i.e., no filter paper). Kanamycin inhibited neo-PLB formation on TC medium, the negative impact being greater on a single layer than on a double layer of filter paper, i.e., filter paper buffered the growth-inhibiting characteristics of kanamycin. Up to 100 mg/l, cefotaxime showed no apparent negative effects on neo-PLBs formation and growth, although hyperhydricity was observed when filter paper was not used.
