Once again, the World has been faced with an oil price shock as a result of the SARS-CoV-2 coronavirus pandemic. This has resurrected an old debate of whether retail fuel prices adjust significantly to either increases or decreases in international crude oil prices. With many countries moving towards the deregulation of their petroleum sub-sector, the impact of the US dollar exchange rate on retail fuel prices cannot be overlooked. This study investigates the rate at which positive and negative changes in international Brent crude oil prices and the US dollar exchange rate affected the increases or decreases in the ex-pump price of premium gasoline between February 2012 and December 2019. Using a non-linear auto-regressive distributed lag model, the exchange rate was found to play a significant role in fluctuations in the retail price of premium gasoline in Ghana and Colombia in the long run, howev-er, the rate of adjustment between the negative and positive changes was not significant, dispelling the perception of price asymmetry. There was no significant relationship between the ex-pump price of premium gasoline and the international Brent crude oil price in Ghana and Kenya in the long run. This study recommends that the aforementioned countries prioritise the creation of ex-change rate buffers to prevent exchange rate shocks that may affect retail fuel prices.

This study examines the impact of financial globalisation on stock market volatility in 24 countries, based on yearly observations from 1993 to 2019. Previous research shows that growing global financial linkages are decreasing countries’ stock market volatility. The financial globalisation composite index consists of two indices. The first is the de facto index, which measures the actual activities and flows between a country and other parts of the world, and the second is the de jure index, which expresses the conditions and policies that enable these activities and flows. According to the authors’ results, the de facto index has no significant effect on countries’ stock market volatility, while there is a significant negative relationship between the de jure index and stock market volatility, underlining the importance of policies and conditions conducive to financial globalisation.

The primary aim of this study is to build a personality profile for financial sales personnel based on Super’s Work Values Inventory that will help select the best candidates for sales staff in the financial and insurance sectors. This personality profile could be used to decide whether a candidate’s psychometric characteristics are suitable for a financial sales position and meet the requirements of the profession as well as the general expectations of the given firm. To attain this aim, a comparative personality test was conducted in Hungary for the first time on a sample of 1,000 people working in the financial and insurance sectors. The following hypothesis is proposed by the author: Regarding sales associates in the financial and insurance sectors, the number of Super’s Work Values Inventory principal components and the items connected these principal components show a significant difference from the results of a 2006 Hungarian survey. The findings confirm this hypothesis.

This study examines whether various environmental factors and the socio-economic status of families influence academic achievement (cumulative grade point average) of students at Asmara College of Education (Asmara, Eritrea). A questionnaire survey was conducted among students to gather information on this subject. Descriptive statistics, crosstabs, Person chi-squared tests were used and analysis of variance was performed by the authors to study data. The results indicate that none of the variables examined, except gender of students and learning resources pro-vided by their families to them, affect cumulative grade point averages. Many students perceive that their academic achievement could be improved instead by building intrinsic motivation, plan-ning, and effective time management. Furthermore, Eritrea provides free education at all levels, including higher institutions, which thereby minimizes socio-economic constraints and provides equal opportunities to all citizens. However, parents should pay attention to their children to im-prove their academic performance, while colleges should also support students by providing a conducive environment for learning.

Maturity models (MMs) are based on the premise that improved maturity in organisational capabilities leads to improvements in the desired outcome measures. This promising potential explains the growing popularity of MMs and the large number of publications on the subject in various academic and professional journals. The present study is based on an analysis of 339 MM papers published in 193 journals between 1973 and 2017. After giving a brief overview of the theoretical underpinnings of MMs, the authors focus on answering the question of ‘where to publish to achieve maximum impact’ from the perspective of potential authors. The impact of a publication, measured by the number of citations collected over its lifetime, is influenced by the quality of the journal (measured by the journal’s article influence score by Clarivate Analytics, Scimago Journal Ranking by Scimago, and Scimago Q category) and the length of public availability of the publication. Results from a variety of partitioning models (decision tree, bootstrap forest, and boosted tree) show that publishing in high-quality, recognised journals tends to result in more citations. In other words, in a network of journals, not all citations are equal as citations in selective, highly ranked journals are more equal than others. It is also important to emphasise that Scimago’s Q classification has no bearing on a paper’s post-publication success; Q classification is a noisy and poor measure of a journal’s quality that is not used globally.

This study aims to comparatively analyse the front office operations of two Hungarian gov-ernment windows, one located in a capital city district and the other in a county district centre, to examine the difference in the perceived service levels. First, through an international literature review, the study describes the background of the government window system and the importance of key performance indicators (KPIs). In addition, it demonstrates how KPIs can be measured in a public service context, regardless of the type and complexity of a given service. Second, the study provides a detailed statistical analysis and a comparison of the typical administrative public services related to waiting times, processing times, and lead times. Moreover, it offers an analogy of industrial service process management by presenting how the selected meth-ods and measures can be used to review processes related to an industrial, a manufacturing, or a public service, following a holistic management approach. The study contributes to the literature by using KPIs of the private sector and industry in public service processes and shows how these common KPIs can be measured in the public service context to provide valuable insights into service processes. Finally, it demonstrates the differences between the KPIs of the government windows to help legislators to increase the efficiency and effectiveness of services.

The challenges faced by official statistics in the 21st century are manifold. We are surrounded by systems that are becoming substantially more complex. The emergence of new phenomena, such as globalisation, digitalisation, has increased the complexity of the reality that needs to be meaningfully and timeously captured by official statistics; it has resulted in the development of new patterns, routes, and types of data, giving us the opportunity to further improve the relevance of statistics. In response to these trends, we need to find new tools and methods for the measurement of these dynamic phenomena. Network theory is an innovative approach that can help us handle the complexity of the 21st century. However, so far it has not featured in mainstream official statistics.

The sophisticated and extensive toolkit for designing, managing, and measuring industrial processes is constantly expanding and forced to meet the new standards that are set by the limitless amount of data offered by the digitalisation of the industrial environment. However, services are managed under cumbersome conditions, in terms of expectations, measurability, and the modelling techniques used. Key performance indicators (KPIs) have been used for a long time in the private sector and industry compared with the public sector. Companies often use KPIs to measure the performance of individual processes to determine whether they meet or fail the expectations of customers and themselves. While public sector service providers are often monopolistic, the performance measurement also becomes a hot debate in the public sector as the citizens’ demand for quality services increases. This study aims to identify objective KPIs and demonstrate how they can be measured in a public service context, regardless of the type and complexity of the given service. As an example, the authors discuss the front office operations of government windows and the contact affair procedures of guardianship offices. They apply business process modelling in order to map the service processes and perform a statistical analysis to extract waiting, processing and lead times from the available dataset to comprehensively overlook these services. Their goal is to offer an analogy of industrial service process management by presenting how the methods and measures can be used to review processes in an industrial, manufacturing or public service, using a holistic management approach.
