This study aims to examine stock price synchronicity during the COVID-19 crisis using 32,452 firms from 61 countries. This paper explores the impact of government effectiveness on synchronicity while distinguishing between developed and emerging markets.

The research analysis employs ordinary OLS pooled regression analysis.

This paper presents worldwide evidence that stock price synchronicity was significantly higher during February and March 2020. This paper shows that synchronicity increased with the intensity of the crisis. In addition, the government's role reduced the COVID-19 impact on synchronicity, which was stronger in developed markets than in emerging markets.

The novelty of the study lies in documenting the impact of the COVID-19 pandemic on stock price synchronicity. The findings add to a deeper understanding of market behavior amid significant disruptive shocks.

The study focused on dimensions of consumer‐based brand equity, and especially the recall level of brand awareness. The purpose was to identify any statistically significant differences in brand recall in various product categories and different national contexts.

This observation study explored relations between consumers' awareness of brands, attitudes related to brand equity, and changes in cultural context. Questionnaire data was collected from university students in four countries: the USA, Finland, France and Sweden. The respondents were asked about the brands of beverages, computers and cell‐phones that first came into their minds, and their attitudes in relation to brand equity.

It seems that the four dimensions of brand equity co‐vary depending on the cultural context. The results also revealed a relationship between TOMA and the national context that was generalizable in the three product categories.

Culture as a contextual factor of consumer brand equity should be studied further. The findings should be replicated with non‐student samples in other product categories and cultural contexts. SEM could be used to establish the causality and direction of the relationships between the various dimensions of culture and brand equity.

The findings on the effect of the cultural context on brand equity are of practical relevance to marketing managers: they should tailor their branding strategies accordingly.

The results gave valid and reliable evidence of a relationship between the TOMA dimension of brand equity and the national cultural context.

Brand heritage is acknowledged as one of the future priorities in branding research. Adopting it in an international context is challenging. In order to maximise its use it is necessary to know how strong it and the target country's cultural heritage are. Accordingly, the aim of the study is to construct a pioneering operationalisation of both brand and cultural heritage.

The study begins with a discussion on the focal concepts. Definitions are proposed and suggestions for operationalisation put forward. Thereafter, the concepts are applied in an analysis of brand heritage in different countries.

It is suggested that brand heritage is a mixture of the history as well as the consistency and continuity of core values, product brands, and visual symbols. A country's cultural heritage could be conceived of as homogeneity and endurance.

The preliminary operationalisation of the concept needs to be further tested. Nevertheless, the clarification and suggestions offered here should open up opportunities for further research.

The exploitation of brand heritage in international markets is likely to be further accentuated. The operationalisations generated are easy for practitioners to apply, enabling companies to better evaluate what brand heritage means for them and to effectively plan its use in an international setting.

To the authors' knowledge, this study is the first to suggest operationalisations of brand heritage and cultural heritage.

Research and development pursuits have always been an integral part of a teacher’s professional development. Today, the higher educational institutes (HEIs) are chiefly prioritizing and providing a sustained support toward research-based and research-oriented learning. But as revealed by the broad outlines of the entire scenario, a fall in research productivity and developmental attempts is witnessed among the faculties of higher educational establishments. To put it succinctly, the motivating aspects that reinforce such activities are not adequately taken care of and have thwarted their progression. The purpose of this paper is to delve deep and explore the factors that inspire teachers toward an enriched research and learning, which equally gets reflected in their teaching practices.

This is a descriptive research with a cross-sectional survey on faculties from different HEIs of West Bengal. A questionnaire has been designed with a five-point Likert scale to draw the primary data. Convenience sampling technique has been utilized. Exploratory factor analysis and confirmatory factor analysis have been performed with structural equation modeling on the hypothesized research model through AMOS.

The major findings of the research have revealed that improved research and development activities of faculties had an immense impact on their teaching quality. The level and accessibility of infrastructure posits a strong influence in augmenting a teacher’s research and developmental endeavors. Working climate influences teachers’ research activities as well their teaching adroitness.

Results may vary when an extensive study is conducted on teachers of HEIs of two or more states or of the country as a whole. Suppression of the real underlying facts by few respondents may affect the result to a small extent.

When faculties orient themselves toward research intensive learning and teaching, the students actively get involved in a platform of greater interaction. It elevates their persistence level, intellectual curiosity, critical thinking and cognitive skills. Research-based teaching is also instrumental in honing their analytical skills, promoting creativity.

The study identified a vital role of the higher education institutes in motivating the faculties toward research-based teaching. There is a dearth of empirical research in identifying the factors that enrich the learning patterns and research activities of the teachers. Thus, it can prove to be a constructive study if implemented.

Nutrition education is an important measure to improve dietary habits and food choices, since poor dietary habits are the main reason for poor nutritional status of adolescents. In this context, the purpose of this paper is to assess the impact of nutrition education on the nutritional and dietary profile of adolescents and early adults.

A pre‐test post‐test experimental design was employed and the study was a cross‐sectional study. From three stratified areas of Benghazi city, two schools were selected by random sampling. From the total of six schools, all the children aged 14‐21 years were selected, amounting to 111 girls and 89 boys. Nutrition education was imparted after initial nutritional (BMI, physical activity) and dietary assessment (food frequency, 24 hour recall) and repeated at weekly intervals. After three months, nutritional and dietary assessments were again repeated.

No significant changes in BMI and physical activity were observed. A significant reduction in the frequency of intakes of chocolate (p < 0.01), chips (p < 0.01), bread and fast food in the female subjects and bread (p < 0.01), cereals and chocolate in the male subjects were observed. Significant increases were observed with respect to percentage of RDA met by intake of nutrients such as energy, carbohydrate, riboflavin and niacin and a significant decrease in the intake of zinc in male subjects.

The paper shows that nutrition education is the need of the hour, which would help adolescents and early adults to imbibe healthy eating habits.

Switches and crossings (S&Cs) are an important component of Banverket's (the Swedish National Rail Administration's) infrastructure and are associated with 13 per cent of the total maintenance cost. Therefore, it is important that a detailed study of different aspects of the costs of S&Cs should be undertaken to analyze individual maintenance costs. This will in the future give the possibility of enhancing the management of infrastructure.

A case study is undertaken to study, identify and classify the costs of S&Cs for Banverket. Data are taken from Banverket's maintenance information systems and accounting system.

A rough estimation of the cost for individual S&Cs can be identified in this way. The cost varies very much and a more detailed study is needed to validate the cost on this level. The average cost of a group of S&Cs varies less and is therefore more likely to reflect the true cost. The cost varies depending on the amount and type of traffic. Moreover, the type of S&C seems to reflect the cost variation, but further investigation is needed to verify this conclusion.

The accounting system does not store data for individual assets, and further research would be more fruitful if individual costs could be recorded by the entrepreneur. Larger repairs should be separated from annual maintenance tasks in a future study. Data from this study could be used to build a life cycle cost model for S&Cs.

Cost identification is a first step in finding a way to organize maintenance in a more cost‐effective way.

The paper shows a way to distribute costs (in the accounting system) down to individual subsystems of the infrastructure. This enables analysts to find cost drivers and plan for modification of or reinvestment in the asset.

The purpose of this paper is to establish a tolerance optimization method based on manufacturing difficulty computation using the genetic algorithm (GA) method. This proposal is among the authors’ perspectives of accomplished previous research work to cooperative optimal tolerance allocation approach for concurrent engineering area.

This study introduces the proposed GA modeling. The objective function of the proposed GA is to minimize total cost constrained by the equation of functional requirements tolerances considering difficulty coefficients. The manufacturing difficulty computation is based on tools for the study and analysis of reliability of the design or the process, as the failure mode, effects and criticality analysis (FMECA) and Ishikawa diagram.

The proposed approach, based on difficulty coefficient computation and GA optimization method [genetic algorithm optimization using difficulty coefficient computation (GADCC)], has been applied to mechanical assembly taken from the literature and compared to previous methods regarding tolerance values and computed total cost. The total cost is the summation of manufacturing cost and quality loss. The proposed approach is economic and efficient that leads to facilitate the manufacturing of difficult dimensions by increasing their tolerances and reducing the rate of defect parts of the assembly.

The originality of this new optimal tolerance allocation method is to make a marriage between GA and manufacturing difficulty. The computation of part dimensions difficulty is based on incorporating FMECA tool and Ishikawa diagram This comparative study highlights the benefits of the proposed GADCC optimization method. The results lead to obtain optimal tolerances that minimize the total cost and respect the functional, quality and manufacturing requirements.

This study aims to develop an optimal tolerance allocation strategy involves integrating the unique transfer (UT) approach and the difficulty coefficient evaluation (DCE) routine in an interactive hybrid method. This method combines the strengths of both UT and DCE, ensuring simultaneous utilization for enhanced performance. The proposed tolerancing model manifests an integrated computer-aided design (CAD) tool.

By combining UT and DCE based on failure mode, effects and criticality analysis (FMECA) tool and the Ishikawa diagram, the proposed collaborative hybrid tool ensures an efficient and optimal tolerance allocation approach. The integration of these methodologies not only addresses specific transfer challenges through UT but also conducts a thorough evaluation of difficulty coefficients via DCE routine using reliability analysis tools as FMECA tool and the Ishikawa diagram. This comprehensive framework contributes to a robust and informed decision-making process in tolerance allocation, ultimately optimizing the design and manufacturing processes.

The presented methodology is implemented with the aim of generating allocated tolerances that align with specific difficulty requirements, facilitating the creation of a mechanical assembly characterized by high quality and low cost. To substantiate and validate the conceptual framework and methods, an integrated tool has been developed, featuring a graphical user interface (GUI) designed in MATLAB. This interface serves as a platform to showcase various interactive and integrated tolerance allocation approaches that adhere to both functional and manufacturing prerequisites. The proposed integrated tool, designed with a GUI in MATLAB, offers the capability to execute various examples that effectively demonstrate the benefits of the developed tolerance transfer and allocation methodology.

The originality of the proposed approach is the twining between the UT and DCE simultaneous in an integrated and concurrent tolerance transfer and allocation model. Therefore, the proposed approach is named an integrated CAD/tolerance model based on the manufacturing difficulty tool. The obtained results underscore the tangible advantages stemming from the integration of this innovative tolerance transfer and allocation approach. These benefits include a notable reduction in total cost and a concurrent enhancement in product quality.
