The Impact

The aim of the study was to generalize the world experience of studying the spatial diffusion of digital innovations in order to determine trends in changing priorities, existing problems and possible prospects for empirical research. With the help of the author’s semantic search algorithm, approximately eighty journal articles published in the last twenty years were found in eight bibliographic databases. The use of a moving average and biproportional indices for quantitative analysis of the array of articles revealed four upward trends: an increase in the average annual number of publications on the subject under consideration, increased attention to the deployment of broadband communications, the impact of spatial diffusion on economic growth and the use of regions as territorial units for studying diffusion processes. An informal analysis of the articles led to the identification of five key problems of modern research: a significant discrepancy between the year of publication and the last year of the process under study, analysis of a limited number of digital innovations, lack of a comprehensive understanding of the joint spatial diffusion of several innovations, the dominance of the idea of the homogeneity for the initial territorial units and the unexplored system of factors contributing to or hindering the spread of digital innovations. Comparing the existing experience of studying the spatial diffusion of digital innovations with similar studies of other types of innovations allowed identifying five promising areas for further research: the use of big data; expanding the set of models used with the subsequent creation of a system of methods; the study of hierarchical, network and other methods of spatial diffusion; the definition of spatial innovation waves with an explanation of the reasons for the formation of territorial barriers and filters; creation of a theory of the spatiotemporal spread of digital innovations based on the generalization of empirical research. The necessity of determining the scope of application of the results obtained in diffusion studies outside of regional economic policy is noted

The Impact

Considering the widespread of Covid-19 and its impact on the population health in Russian regions, it is necessary to examine the impact of the pandemic (as excess mortality) on the regional socio-economic development in 2020. Based on a quantitative and qualitative model, the study explains the process of coronavirus diffusion at the regional level, using information from foreign publications, Russian regional statistics and a database of legal documents «Consultant +». The concept of spatial diffusion, developed in the 1950s-1980s, was chosen as the research methodology. The study methods include a cartographic analysis of the monthly dynamics of coronavirus spread in Russian regions and regression analysis of regional differences in excess mortality regarding the most significant explanatory variables. The developed regression model explains the spread of Covid-19 across Russian regions in 2020, while the proposed qualitative model «network-place-scaling» describes the spatial diffusion of the virus. The conducted analysis confirmed the relationship between the spread of the virus and economic specialisation of regions. Simultaneously, such widely discussed factors as physical density, urbanisation level and per capita income did not show significant correlation with excess mortality. The study revealed the following results. There is a significant discrepancy between the actual situation in Russian regions and expected developments according to the simplified centre-periphery model. The important regression variables, explaining the interregional differences in excess mortality in 2020, include the share of employed in contact-intensive wholesale and retail trade and manufacturing (large production teams); proportion of the population over 65; the number of retail facilities per 1000 people. The qualitative model «network-place-scaling» was deemed suitable for explaining the mechanisms of the spread of coronavirus in Russian regions. Future studies should focus on examining the mechanisms and socio-economic consequences of the pandemic at the municipal level of large cities and urban agglomerations in Russia.

Care System

Purpose. Many aspects of the health care system effective functioning depend on the level of trust in it. The purpose of this work is to study and summarize the research of native and foreign scientists on the topic of trust in the health care system in order to identify the context and methodological approaches to the study of trust. Materials and methods. The author used in the review the method of systematic review of publications based on strict criteria for selecting publications of individual homogeneous original studies. The search was carried out in the bibliographic databases PubMed, Google Scholar. The author included in the review articles that mentioned trust in the health system as part of their research objectives or questions. No reports published in peer-reviewed literature were analyzed. Results and discussion. There are three positions to consider trust from: trust in the personality of a medical worker (interpersonal); institutional trust in medical organizations; trust in the health care system as a whole (systemic). Several studies have looked at trust in the context of public trust in health care. Within the health care system, there are processes of transfer of trust from an individual to an institution and back. Institutional trust has a significant impact on the formation of interpersonal trust. No causal relationship has been established about the impact of trust on treatment outcomes, and patient distrust of healthcare providers can have detrimental health consequences. The degree of trust in the health care system is different in various categories of citizens. Conclusion. The review revealed that there is no sufficiently accurate, theoretically substantiated and empirically verified definition of trust; trust studies are scattered and built around different definitions. The terms are used interchangeably between studies with the same focus and are not clearly defined and distinct. A variety of tools used to measure trust, the use of different concepts, a significant variation in the choice of the subject and object of empirical research, different methodological foundations of research make it difficult to compare and generalize research data, therefore, for further understanding, study, assessment and conduct of empirical research, a theoretical basis of trust is needed.

The Impact

For the effective use of modern tools, the inherent visuo-motor transformation needs to be mastered. The successful adjustment to and learning of these transformations crucially depends on practice conditions, particularly on the type of visual feedback during practice. Here, a review about empirical research exploring the influence of continuous and terminal visual feedback during practice on the mastery of visuo-motor transformations is provided. Two studies investigating the impact of the type of visual feedback on either direction-dependent visuo-motor gains or the complex visuo-motor transformation of a virtual two-sided lever are presented in more detail. The findings of these studies indicate that the continuous availability of visual feedback supports performance when closed-loop control is possible, but impairs performance when visual input is no longer available. Different approaches to explain these performance differences due to the type of visual feedback during practice are considered. For example, these differences could reflect a process of re-optimization of motor planning in a novel environment or represent effects of the specificity of practice. Furthermore, differences in the allocation of attention during movements with terminal and continuous visual feedback could account for the observed differences.

Future Growth

Obtaining dietetic licensure in Ontario requires completion of a Dietitians of Canada (DC) accredited four-year undergraduate degree in nutrition and an accredited post-graduate internship or combined Master’s degree program. Given the scarcity of internship positions in Ontario, each year approximately two-thirds of the eligible applicants who apply do not receive a position XX, XX, XX, XX, XX, XX, in press). Anecdotally, not securing an internship position is known to be a particularly disconcerting experience that has significant consequences for individuals’ personal, financial, and professional well-being. However, no known empirical research has yet explored students’ experiences of being unsuccessful in applying for internship positions. Fifteen individuals who applied between 2005 and 2009 to an Ontario-based dietetic internship program, but were unsuccessful at least once, participated in a one-on-one semi-structured interview. Findings reveal that participants’ experiences unfold successively in four phases that are characterized by increasingly heightened emotional peril: naïveté, competition, devastation, and frustration. The authors conclude that the current model of dietetic education and training in Ontario causes lasting distress to students and hinders the future growth and vitality of the dietetic profession. Further research is required to understand the impact of the current model on dietetic educators, internship coordinators, and preceptors as coincident participants in the internship application process.

It is still found that investigating officers do not have an S1 degree or equivalent in thejurisdiction of the Sambass Resort Police as mandated in PP No. 58 of 2010 concerningAmendments to Government Regulation Number 27 of 1983 concerning theImplementation of KUHAP article 2A paragraph (1) letter a. If the requirements ofinvestigators are not fulfilled, there will automatically be limits of authority, includingthe inability to issue investigation orders, detention warrants and other administrativeletters. This study used a qualitative method with juridical empirical research. Toobtain accurate data, purposive sampling technique was used, and primary datacollection by conducting in-depth interviews. The research results found, among others:first, discretion regarding the administration of investigations in the jurisdiction of theSambas Resort Police for the Sambas District Police who do not have investigatingofficers who meet the requirements, is then taken over by the Head of the CriminalInvestigation Unit as the supervisor of the integrated criminal investigation function.Second, the impact of an integrated investigation administration causes the time tocarry out investigations to be slow due to the long distance between the Sector Policeand the Resort Police.

BACKGROUND Since the beginning of the COVID-19 pandemic, researchers and health authorities have sought to identify the different parameters that govern their infection and death cycles, in order to be able to make better decisions. In particular, a series of reproduction number estimation models have been presented, with different practical results. OBJECTIVE This article aims to present an effective and efficient model for estimating the Reproduction Number and to discuss the impacts of sub-notification on these calculations. METHODS The concept of Moving Average Method with Initial value (MAMI) is used, as well as a model for Rt, the Reproduction Number, is derived from experimental data. The models are applied to real data and their performance is presented. RESULTS Analyses on Rt and sub-notification effects for Germany, Italy, Sweden, United Kingdom, South Korea, and the State of New York are presented to show the performance of the methods here introduced. CONCLUSIONS We show that, with relatively simple mathematical tools, it is possible to obtain reliable values for time-dependent, incubation period-independent Reproduction Numbers (Rt). We also demonstrate that the impact of sub-notification is relatively low, after the initial phase of the epidemic cycle has passed.

True Structure

The general AutoRegressive Integrated Moving Average (ARIMA) model can be written as the sum of noise and exogenous components. If an exogenous impact is trivially small, the noise component can be identified with the conventional modeling strategy. If the impact is nontrivial or unknown, the sample AutoCorrelation Function (ACF) will be distorted in unknown ways. Although this problem can be solved most simply when the outcome of interest time series is long and well-behaved, these time series are unfortunately uncommon. The preferred alternative requires that the structure of the intervention is known, allowing the noise function to be identified from the residualized time series. Although few substantive theories specify the “true” structure of the intervention, most specify the dichotomous onset and duration of an impact. Chapter 5 describes this strategy for building an ARIMA intervention model and demonstrates its application to example interventions with abrupt and permanent, gradually accruing, gradually decaying, and complex impacts.

Volunteering, the volunteer’s intercultural competence and emotional intelligence contribute to intercultural education and sustainability in various societies of today. The aim of this study was to analyse the impact of emotional intelligence and intercultural competence on work productivity of volunteers. The first part of the article substantiates theoretical associations between emotional intelligence, intercultural competence and work productivity. Based on theoretical insights, empirical research methodology was prepared, which consisted of four categories divided into sub-categories that provided the structure of the question groups. The empirical research involved seven informants working in Lithuania, who welcomed volunteers from abroad. The research was conducted using the method of semi-structured interviews. The conclusions present a systematic perspective towards the role of emotional intelligence in the intercultural competence and work productivity of volunteers. In this context, emotional intelligence works as a mediating factor. The contributing role of volunteer-receiving organisations in the development of the volunteers’ emotional intelligence is also highlighted.

The Impact

Integrating circularity in business strategy is difficult to achieve for companies as it requires impactful changes in core business processes. While research has focused on identifying key barriers, little is known about the organizational attributes that can assist businesses in integrating circularity in their strategies. The purpose of this study is to investigate the implications of organizational managers and network interactions for the integration of circularity in business strategy. Through using survey data from 627 SMEs (small- and medium-sized enterprises) in the Netherlands, this study shows that managers who interpret circularity as an opportunity can have a positive direct and indirect effect on the integration of circularity in a company’s strategy. The results furthermore highlight the importance of circular network interactions for the integration of circularity in business strategy. This article contributes to recent calls for more empirical research into the integration of circularity and offers relevant insights for companies aiming to integrate circularity.
