The emergence of the COVID-19 pandemic changed the way in which education was delivered in early 2020, and the impacts of these changes continue to be questionable. The aims of this study were to evaluate: (1) the results obtained by students of the Dentistry course in the progress test carried out both before and after the pandemic, (2) the results obtained by a specific group of students who took the test in 2019–2022, and compare their results and (3) subjects that showed a reduction in the percentage of correct answers when the two tests were compared.

The progress test consisting of 100 multiple choice questions was applied before and after the pandemic to all students in the Dentistry course. The analyses were performed using the IBM SPSS for Statistics v.26 software program. The level of significance of 5% was adopted (<0.05).

The test was applied to 320 students in 2019 and to 272 in 2022, of whom the sample of this study was composed. The mean score values in 2019 (M = 49.10; SD = 12.03) were significantly (p = 0.026) higher than those in the year 2022 (M = 46.97; SD = 12.15), with the disciplines in the area of specific knowledge showing a greater drop in the percentage of correct answers by students. This study showed that the emergency remote education had a negative effect on the academic performance of students, based on the progress testing as an evaluation method.

Many studies that assessed the impacts of the pandemic on teaching were focused on the opinions of students. However, the great advantage of our study was the use of a theoretical assessment tool to verify student performance. The post-pandemic landscape beckons for comprehensive inquiries into these domains. This type of research would be valuable for gathering evidence relative to the performance of students after the emergency remote education.

The purpose of this paper is to identify the determinants of dividend policy in an emerging and developing market.

The study employs a quantitative approach using 191 Sri Lankan firms and 1,337 firm-year observations as the sample. The authors apply a Binary Logistic Regression model to uncover the determinants of the propensity to pay dividends, and a Fixed Effect Panel Regression to investigate the determinants of dividend payout.

The authors identify past dividend decision, earnings, investment opportunities, profitability, free cash flow (FCF), corporate governance, state ownership, firm size and industry influence as the key determinants of propensity to pay dividends. In addition past dividends, investment opportunities, profitability and dividend premium are identified as the determinants of dividend payout. Moreover, there is a feedback between dividend yield and profitability in one lag and between dividend yield and dividend premium in two lags, as short-term relationships. Hence, past dividend decision or payout, profitability and investment opportunities are a common set of determinants with implications for both propensity to pay dividends and its payout. The findings support theories of dividends such as signaling, outcome, catering, life cycle, FCF and pecking order.

The findings are important for investors, managers and future research. Investors should focus on the determinants identified by our study when making investment decisions whereas managers should practice the same when formulating appropriate dividend policies for their firms. Future research should rely on propensity to pay dividends and its payout simultaneously to promote a theoretical consensus on the dividend determinant puzzle.

This is the first study that investigates determinants of propensity to pay dividends and dividend payout along with short-term relationships in a single study.

This paper aims to address shortcomings of current tiltrotor designs, such as the small aspect ratio of the wings, large download and the close proximity of the rotor tips. It also aims to avoid the complex transition of tiltrotors to normal airplane mode.

This design combines tiltrotor and tiltwing aircraft designs into a hybrid that is augmented by active flow control, using a gimbaled channel wing for attitude control in hover.

The proposed hybrid design is based on experimental results of components that were tested individually for potential use in hover and steep ascend from a stationary position.

This research was inspired by the extremely short take-off of the V-22, when its rotors were tilted forward. It combines several design approaches in a unique way to achieve extremely short take-off capabilities combined with high-speed and reduced maintenance costs.

The purpose of this study is to simulate the climate change impacts on winter wheat production and evaluate the possibilities of using various varieties and shifting planting date as two climate change adaptation strategies in Kerman Province, Iran.

Two types of global circulation model and three scenarios for three periods were used. Daily climatic parameters were generated by LARS-WG (Long Ashton Research Station-Weather Generator). The CERES-wheat model was used to simulate future winter wheat growth, development and production.

The results showed that CO₂ had no effect on the phenology of winter wheat, and the negative impact of temperature on the grain yield was higher than the positive effect of CO₂ enrichment. The length of the reproductive growth period of the winter wheat was significantly shortened as affected by the negative impacts of rise in temperature. The simulated results indicated that the grain yield of common (medium maturing) variety of winter wheat will decline, ranging from −0.27 to −18.71 per cent according to future climate changes. Adaptation strategies showed that the early maturing variety had a higher and more stable grain yield under climate change conditions than medium and delayed maturing varieties. Earlier planting date (20 October) increased wheat grain yield under future climatic conditions than common (November 5) planting date. In reverse, later planting (November 20) would accelerate harmful effects of climate change on wheat grain yield.

The results highlighted the potential of early maturing variety and early planting date as the appropriate agronomical approaches for mitigating harmful impacts of climate change on winter wheat production in arid regions.

This study investigates Singaporean millennials’ attitudes toward luxury brands. The research focuses on the financial, functional, individual, and social dimensions of luxury value perception and whether ethnicity influences these dimensions.

The research measures luxury value perception among millennials of the three main ethnic groups in Singapore (Chinese, Indians, and Malays) via more than 200 questionnaires. Data were analyzed through Kruskal-Wallis non-parametric ANOVA and cluster analysis.

Luxury value perception does not vary across ethnicity, with the exception of the financial value dimension. Four market segments of young luxury consumers in Singapore are identified and profiled. These segments do not differ in terms of ethnicity.

Millennials are an evolving and moving population segment, and thus longitudinal analyses would be useful to develop a more comprehensive understanding of this segment.

Ethnicity does not affect luxury value perception. The results of the cluster analysis suggest that luxury companies should address the millennials as a global target sharing the same luxury value perception. At the same time, luxury companies can emphasize some different aspects (i.e., the financial dimension) of their value offer.

The research studies the most interesting market for luxury brands—millennials—in a fast-growing luxury market. It adds knowledge to the previous literature on luxury value perception. This research can guide managers to devise suitable marketing strategies addressing the millennials segment as a global market that has the same set of luxury values worldwide.

This paper aims to provide a comprehensive view of the different competition-based approaches that policymakers can exploit to foster external knowledge search and their positioning among innovation policy measures. A growing number of companies have implemented initiatives to access external knowledge to increase their innovativeness, consistently with the open innovation paradigm. Competition-based approaches have received increasing attention by the private sector as a way to access external knowledge. However, despite their potential role as innovation policy measures, a limited attention has been devoted so far to investigate them from the policymakers’ perspective.

To this aim, a two-stage empirical analysis has been carried out to develop a taxonomy of competition-based approaches. The first stage leveraged a multiple case study methodology including a sample of 20 competition-based approaches, while the second one leveraged interviews with Italian and European key informants.

This paper proposes a novel taxonomy including eight competition-based approaches, which differ among each other in terms of policy strategy, scope breadth and output required. Moreover, this paper enriches a well-established taxonomy of innovation policy instruments with the identified competition-based approaches.

This study contributes to the current debate on innovation policy by providing a taxonomy that includes eight competition-based approaches that can be exploited by policymakers to foster external knowledge search as well as their positioning among the innovation policy instruments. The taxonomy will hopefully support policymakers in identifying of the most suitable instruments in the light of their policy strategy and objectives.

On a home game weekend of collegiate football, thousands of fan visitors spend their weekend participating in college football games, showing significant potential of sports tourism businesses in the USA. Understanding the original personality of sport tourists and their travel motivation factors is imperative to develop appealing tourist attractions at the destinations of sports team fandoms. The purpose of the study is to examine the relationships among tourists' personality characteristics, their push and pulls motivations, satisfaction with travel experience, and loyalty toward destination and team using structural equation modeling.

The author collected information from a total of 301 sports tourists who had traveled to a college football game within the past year, staying at least one night in a hotel or other lodging place. This study employed PASW Statistics 25.0 and structural equation modeling using LISREL 9.30 for data analyses.

Personality has a significant relationship with push factors, especially for socialization motivation, and pull factors (i.e. access and affordability, other attractions) had more significant effects on sports tourists' satisfaction than push factors. The findings indicate the key roles for the entertainment motivation in generating tourists' satisfaction and destination loyalty and important roles of destination loyalty in building team loyalty.

The present study provides an approach of sports tourists' travel behaviors and experiences in the sporting event tourism. The outcome of this research can help both sports event organizers and destination marketers to understand the motivations for sports game attendance and to develop marketing strategies and products/services for attracting various types of sports tourists to games.

Food insecurity in the Latin American region has become a complex problem that significantly impacts people's physical and mental well-being. The factors causing food insecurity are varied, ranging from social, political, and economic causes. Ensuring access to food is not a task with limited responsibilities; on the contrary, both public and private institutions must contribute to creating sustainable and innovative solutions. In general, it is necessary to ensure that the food system flows correctly, ensuring the availability of balanced and nutritious food for the diet of the inhabitants of a given nation. Alternative solutions apart from the government's help include sustainable cultivation, finger millet, and close cooperation with the farmers from the agriculture sector. The present research aims to consolidate theoretical information on the Latin American situation and seek the leading solutions of the parties involved.
