This study examines the relationship between infrastructure and trade performance in West African countries during the 1990-2021. It moved a step further over the existing studies in this area to explore the effect of education and energy finance on trade flow in the region. The theoretical framework is based on the love of variety theory as advocated by Krugman [1] and modified to suit purpose. This emphasis here is on derivation of utility from a given varieties of choices which in turn boost production, specialization, positively externalities and economies of scale. Results of the robust least square show the declining effects of mobile phone subscriptions and increasing effect of government expenditure on education though not as expected. Investment in energy appears insufficient to boost trade performance in the region.
The Wald test shows that causality occurs between import trade and infrastructure financing variables.

The article presents the problem of the undetermined methodology for calculating energy savings in production processes, which is the scorecards content of the tender documents of the European Cohesion Policy for the current period until 2027. The consequence of such undetermined approach results in wrong decisions of evaluators and consequently, irrational distribution of taxpayers’ money. Presented methodology is a solution that guides the user step by step and results in data that are comparable with each other. The methodology equalizes the possibilities of including companies from different sectors and prevents the creation of non-expert assessments.

The broad objective of this study is the analysis of the long and short run effect of government expenditure on yam yield in Nigeria. The study applied descriptive statistics and autoregressive distributed lag (ARDL) econometric approach to the secondary data collected from Central Bank of Nigeria Statistical Bulletin and FAOSTAT. The descriptive analysis shows that yam output was increasing in Nigeria with decreasing trend in yield. The result of the econometric analysis indicates that agricultural government expenditure does not have significant long and short-run effects on yam production and yield. This is because the real per capita agricultural government expenditure is small. The study concludes that although, agricultural government expenditure does not have significant long and short-run effects on yam production and yield, it is positively correlated with agricultural inputs used in yam production. Based on the findings from the study, various recommendations were made, which include the need to increase the share of agricultural public expenditure in total government expenditure in Nigeria, which stood at 2%, can be increased to 4% which is the average for Sub-Sahara Africa, while targeting 10% recommended in the Maputo Declaration.

Employment opportunities for graduates are an important issue. This study has two objectives: analyzing female graduates’ employment participation and investigating the factors affecting women graduates’ employability in engineering and technology education in Ethiopia. Secondary data have been analyzed to establish women graduates’ involvement in STEM employment using graduation and employment data. Primary data were collected from 384 women graduates of engineering and technology education. The Probit model results reveal that the unemployment of engineering and technology graduated women are negatively influenced by communication skills, Academic performance (cumulative GPA), willingness to migrate from one place to another for searching jobs, and non-technical skills. While job preference and marriage impact women’s unemployment positively. Hence, graduated women themselves, the government, and other stakeholders should enhance women graduates’ employment opportunities. Such as graduates must improve their communication skills and non-technical skills, record better grade points, and be ready to go everywhere to find jobs. They must also be prepared to do available work, become an entrepreneur, and decide for late marriage until they have a job. The government must create a channel between universities and firms through teaching with a work placement curriculum, more concern on practical works, approve the peace and security of citizens, and expand infrastructure.

The Indian economy has witnessed significant increase in exports of services in the recent years. The present study analyses the trends, competitiveness and direction of India’s services exports for the period 2010 to 2020. It can be inferred that the exports of two services, viz.; telecommunications, computer and information services and other business services dominate the services exports. The impetus mainly comes from computer services and professional management and consultancy services. Similarly, the comparative advantage for India also lies in the export of telecommunications, computer and information services and other business services. Furthermore, it has been found that the intensity of exports of these two services is more to emerging economies from East Africa and South Asia. The analysis points out that the Indian economy has been emerging as one the major services provider from the Global South in the recent years.

Teachers are the key to education formalization. The study found that the Internet capital of rural teachers in western China is obviously insufficient. Compared with teachers in developed areas, there are significant differences in network facilities, information technology knowledge, online learning and information literacy. The backwardness of network facilities and the lack of information technology knowledge are the important reasons for the lack of Internet capital of rural teachers in western China. Therefore, it is necessary to improve the Internet capital of rural teachers in western China from the aspects of network facilities construction, network knowledge transfer, online learning support and online learning reflection. The proposal of these measures has certain reference value for promoting the improvement of rural teachers’ Internet ability in western China and narrowing the gap with teachers in developed areas.

Public welfare marketing is an effective method for brands to improve their reputation and credibility. With the development of the Internet and social platforms, public welfare marketing needs new strategies to better play its role. This article summarizes the effective strategies for brand public welfare marketing in the context of new media by analyzing the public welfare marketing projects of the Perleya brand since 2021. Research has found that brand public welfare marketing needs to target the target audience, increase user engagement, and endow the brand with a certain image and spirit that meets consumer expectations through public welfare marketing. At the same time, public welfare marketing should strive to resonate emotionally with consumers, awaken the emotional factors of the audience, and also rely on the power of KOL and authoritative institutions to increase communication efforts and achieve the transfer of trust.

This paper discusses the effects of theoretical planning and framework of humanitarian aid and disaster relief. In order to ease the understanding of this theoretical topic this essay will preoccupy itself by conducting a case study: Therefore, the theoretical framework of the Turkish disaster relief institution “Disaster and Emergency Management Presidency” (AFAD) will be analyzed in depth and set into the context of the number of earthquake that took place in South East Turkey and Syria in February of 2023. The more, the success of the theoretical framework established by AFAD will be critically analyzed by comparing it to its practical implementation during the first seven days following the first big earthquake. The study results by concluding that the practical application of the framework on disaster relief and humanitarian aid was highly flawed due to interpersonal problems, affiliations and as a result of a centralized bureaucratic reform.
