We present an approach for pricing American put options with a regime-switching volatility. Our method reveals that the option price can be expressed as the sum of two components: the price of a European put option and the premium associated with the early exercise privilege. Our analysis demonstrates that, under these conditions, the perpetual put option consistently commands a higher price during periods of high volatility compared to those of low volatility. Moreover, we establish that the optimal exercise boundary is lower in high-volatility regimes than in low-volatility regimes. Additionally, we develop an analytical framework to describe American puts with an Erlang-distributed random-time horizon, which allows us to propose a numerical technique for approximating the value of American puts with finite expiry. We also show that a combined approach involving randomization and Richardson extrapolation can be a robust numerical algorithm for estimating American put prices with finite expiry.

The paper discusses a partnership between Huston–Tillotson University (HT), a Historically Black College and University (HBCU) and the Austin Independent School District (AISD), a minority-serving school district, both in Austin, Texas, with a grant provided by Apple Inc. (Apple). The purpose of the partnerships is that valuable relationships can increase the number of African American male teachers in primary and secondary education in minority-serving public schools. The African American Male Teacher Initiative (AAMTI) at HT was created as an innovative approach to recruit and select 20 African American males each year of a four-year grant provided by Apple.

This paper reviewed the literature on the lack and need for African American male public school teachers. Once the data is established during a three-to-four-year period, a mixed-method approach will be utilized to examine data retrieved from interviews, surveys, demographics of student participants, numerical data and retention and graduation rates. This will establish whether strategic partnerships can successfully increase the number of qualified African American males in public education.

This paper proposes and provides research evidence that African American male teachers can positively impact all students in the classroom setting.

There is limited data to test a hypothesis on the effectiveness of a partnership between the university and public school to increase the number of African American male teachers through recruitment – selection and retention efforts. Therefore, follow-up research is needed for the first graduating class of 2024.

The broader impact of this paper is to show that partnerships between universities and public schools with corporate sponsorship can positively increase the number of African American male teachers prepared to teach in public schools through strategic recruitment and selection efforts.

This paper can serve as a model for universities and school districts to implement. High placement of prepared Black male teachers in public schools can reduce the school-to-prison pipeline and juvenile homicides and defeat generational poverty.

Much research highlights the problems associated with a lack of African American male teachers. This paper includes the challenges but offers a sound basis for practical solutions.

This case study paper aims to explore the complexities and challenges of epidemic response and public health surveillance in Native American and Indigenous American communities in the United States and find viable solutions. This paper explores these topics through the emergence and impact of the hantavirus pulmonary syndrome (HPS) within the Navajo Nation in the United States using critical incident analysis and best practices.

This project is a case study paper based on a topical review of the literature. A topical review of the literature is a comprehensive exploration of the current body of knowledge within a particular research field. It is an important tool used by scholars and practitioners to further the development of existing knowledge as well as to identify potential directions for future research (Fourie, 2020). Such a paper can provide a useful insight into the various aspects of the process that the researcher may have overlooked, as well as highlighting potential areas of improvement (Gall et al., 2020). It can also provide a useful source of ideas and inspiration for the researcher as it can provide an overview of the various approaches used by other researchers in the field (Göpferich, 2009). Case study papers using a topical review of the literature have been used to help frame and inform research topics, problems and best practices for some time. They are typically used to explore a topic in greater depth and to provide an overview of the literature to improve the world of practice to provide a foundation for future comprehensive empirical research. Case study papers can provide research value by helping to identify gaps in the literature and by providing a general direction for further research. They can also be used to provide a starting point for research questions and hypotheses and to help identify potential areas of inquiry.

This study explores best practices in public health surveillance and epidemic response that can help strengthen public health infrastructure by informing the development of effective surveillance systems and emergency response plans, as well as improving data collection and analysis capabilities within Native American and Indigenous American communities in the United States that also have the option to include new technologies like artificial intelligence (AI) with similar outbreaks in the future.

The literature review did not include any primary data collection, so the existing available research may have limited the findings. The scope of the study was limited to published literature, which may not have reported all relevant findings. For example, unpublished studies, field studies and industry reports may have provided additional insights not included in the literature review. This research has significant value based on the limited amount of studies on how infectious diseases can severely impact Native American communities in the United States, leading to unnecessary and preventable suffering and death. As a result, research on viable best practices is needed on the best practices in public health surveillance and epidemic response in Native American and Indigenous American communities through historical events and critical incident analysis.

Research on public health surveillance and epidemic response in Native American communities can provide insights into the challenges faced by these communities and help identify potential solutions to improve their capacity to detect, respond to and prevent infectious diseases using innovative approaches and new technologies like AI.

More research on public health surveillance and epidemic response can inform policies and interventions to improve access to healthcare for Native American populations, such as increasing availability of healthcare services, providing culturally appropriate health education and improving communication between providers and patients. By providing better public health surveillance and response capacity, research can help reduce the burden of infectious diseases in Native American communities and ultimately lead to improved public health outcomes.

In this paper, the authors suggest that Central Americans can use entrepreneurship to solve economic uncertainty in their home country and that entrepreneurship can contribute to reducing the number of undocumented migrants to the USA.

The authors first illustrate the context of Central American illegal migration to the USA from a transitional entrepreneurship perspective, the authors address the economic drivers of illegal migration from Central America, which results in marginalization in the USA. Second, the authors build a theoretical model that suggests that Central Americans can improve their entrepreneurial abilities through the entrepreneurial cognitive adjustment mechanism.

Central Americans at risk of illegally migrating to the USA have high entrepreneurial aptitudes. Entrepreneurship can help them avoid the economic uncertainty that drives Central Americans to illegally migrate to the USA and become part of a marginalized community of undocumented immigrants. This conceptual paper introduces an entrepreneurial cognitive adjustment mechanism as a tool for Central Americans to reshape their personalities and increase their entrepreneurial abilities in their home countries. In particular, entrepreneurial intentions reshape the personality characteristics of individuals (in terms of high agreeableness and openness to experiences, as well as low neuroticism) through the entrepreneurial cognitive adjustment mechanism, which consists of reflective action in sensemaking, cognitive frameworks in pattern recognition and coping in positive affect.

This paper studies Central Americans at risk of illegal migration using the lens of transitional entrepreneurship, which advances the understanding of the antecedents to marginalized immigrant communities in the USA and suggests a possible solution for this phenomenon. Besides, the authors build a cognitive mechanism to facilitate the transitional process starting from entrepreneurial intention to reshaping individuals' personality, which further opens individuals' minds to entrepreneurial opportunities. Since entrepreneurial intention applies the same way to all entrepreneurs, the authors' aim of constructing the entrepreneurial intention unfolding process will go beyond transitional entrepreneurship and contribute to intention-action knowledge generation (Donaldson et al., 2021). Moreover, the conceptual study contributes to public policy such that international and local agencies can better utilize resources and implement long-term solutions to the drivers of illegal migration from Central America to the USA.

This paper aims to interpret the multidimensional Asian American identity of immigrant Indians in terms of pan-ethnicity, gender and religion.

The social construction and experience of race in the US and the intersection of multiethnic Asian American identity with race, gender and religion will be used in critically commenting on the interview of primary ethnic identity of Indian Americans including the pan-ethnic identity of Indians in the US as Asian Americans, the Mar Thoma Church community, the second-generation Patel family's union formation in terms of gender identity.

The future directives include Asian American Movement (AAM) which is trying to incorporate Indians as pan-ethnic identity assimilation and the process of holding American identity as primary identification of Indians.

Policy recommendations are that the US Census Bureau should include Indian Americans as separate ethnic identity for Indian immigrants like the Chinese Americans. USCIS (US Citizenship and Immigration Services) should reform policies to include the wives of H-4 visa holders. The Department of Homeland Security (DHS) should provide secure living environment for Indian immigrants. The US Department of Labor should provide equal opportunities for women in their immigration policies.

This paper will critically analyze the interview results of primary ethnic identity and justify the hypotheses of Asian American identity of Indians, whether (1) they merge with the American identity as part of cultural assimilation or (2) retain their Asian identity beyond Americanized identity or (3) go beyond both American and Asian identity to restate their Indian ethnicity.

This study examines the impact of college education on incorporated and unincorporated self-employments. It specifically compares the effects on African Americans and Hispanics with the effects on Whites.

The study sample was drawn from the US Current Population Survey between 1989 and 2018. Based on a sample size of 1,657,043 individuals, this study employed logit regression models to test the hypotheses. Racial variations were examined using African Americans and Hispanics as moderators.

The results suggest that college education increases incorporated self-employment and reduces unincorporated self-employment. The impact of college education on incorporated self-employment is stronger for African Americans and Hispanics than for Whites. In contrast, its effect on unincorporated self-employment is stronger for Whites than for African Americans and Hispanics.

The findings provide empirical evidence of how college experience changes the motivation of starting an incorporated or unincorporated business. The results suggest that college education impacts African Americans and Hispanics differently than Whites in pursuing their career path of entrepreneurship.

It is the first study that examines the relationship between college education and incorporated/unincorporated self-employment. It also sheds light on radical variations.

The purpose of this study is to cover the change that happened in the American foreign policy toward Iran by changing the American leadership from Obama to Trump. In addition to its coverage for the Iranian foreign policy toward the Arab region during the presidency period of Obama in the USA and also during the presidency period of Trump, to discover whether a change has happened in the Iranian foreign policy toward the Arab region is a result of the change in the American foreign policy or not. This can be discovered by concentrating on Yemen, Syria and Iraq, taking into consideration the Iranian and American national interests in the Arab region, as well as the regional role of Iran and its intervention in the Arab region.

This study was based on the analytical method of the foreign policy that is based on analyzing facts and events, as well as analyzing the roles and interests within the framework of the states’ foreign policy. This method was used in the study for the purpose of analyzing the impact of the change in the American leadership from Obama to Trump on the US foreign policy toward Iran in the light of the American interest; in addition to the Iranian foreign policy toward the Arab region (Yemen, Syria and Iraq) in the presidency period of both Obama and Trump in light of the regional role of Iran and its passion to achieve its national interest.

The study concluded that the change in the American foreign policy toward Iran is a result of the change of the American leadership from Obama to Trump by the American interest requirements in accordance to the respective of both of them. The change in the American policy led to a change in the trends of the Iranian foreign policy toward the Arab region in the term of the regional Iranian role. Under the American and Iranian convergence in the period of Obama, the Iranian role in the Arab region was limited to what could achieve its national interest and what did not threaten the American interest, especially after Iran had guaranteed that the USA is by its side. In the framework of the American and Iranian confrontation under Trump’s current presidency, the Iranian role has expanded in the Arab region, where Iran has intensified its intervention in Yemen, Syria and Iraq politically and militarily. Iran became more threatening to the American interest, as it became a means of pressure to the USA under Trump’s ruling in the purpose of changing its position toward it.

The importance of the study stems from the fact that it is seeking to analyze the change of the American foreign policy toward Iran within the period of two different presidential years of Obama and Trump, whereas, their trends were different in dealing with Iran between rapprochement and hostility toward it, on the basis of the American interest. In addition to testing whether this change in the American foreign policy toward Iran has been accompanied by a change in the Iranian foreign policy toward the Arab region.

This paper aims to argue that the Global Political Economy (GPE) theory of neomercantilism provides a sound explanation to the American military involvement in the Persian Gulf. Accordingly, this paper also proposes the concept of “Neomercantilist War” which analyses the use of military force to protect a strategically vital economic resource (such as Gulf oil). Neomercantilist War is a point of similarity between the GPE school of neomercantilism and the International Relations (IR) school of realism.

The 1991 Gulf War and the American invasion of Iraq in 2003 are two major events of American military involvement to protect and/or seize Gulf oil. These two events will be tested for neomercantilism, in addition to the concept of “Neomercantilist War” as presented in the paper. The first feature, or definitional component, of neomercantilism is the major role of the state, the second is the preponderance of security/geopolitical goals over economic goals and the third is the zero-sum, relative gains mentality to dealing between states IR.

The GPE school of neomercantilism and the concept of Neomercantilist War do offer a sound explanation of American military involvement in the Gulf.

The American military involvement in the Gulf region has been analysed using the IR schools of realism and liberalism, but never using GPE theory. Even though GPE is mostly concerned with economic activity, the scope of GPE should be expanded to include military policies if they affect economic resources and activity.

The USA has been suffering from international/transnational terrorism for decades. There is no consensus on whether this situation is a result of the international status of the USA and the principles it upholds or the policies it embraces in its interaction with the outside world.

This study adopts both the “American Primacy” theory and the “anti-Americanism” theory in its effort to reach a conclusion concerning this issue. This study aims to examine previous research that linked international terrorism to the US hegemony and the principles it abides by and showed the relevance of this perception to the “American Primacy” theory. It also examines the research that considered international/transnational terrorism as a result of the American foreign policy in its various aspects (economic, military, assistance or a whole combination of policies).

This literature on the American foreign policy and international/transnational terrorism was extensive and manifested the explanatory power of the “anti-Americanism” theory, especially in its three variants: issue-oriented, ideological and instrumental. While examining the foreign policy terrorism studies, the relevance of the “American Primacy” theory appeared at very few instances.

The study was able to prove that explaining the international/transnational terrorism is related to the foreign policy decisions taken by the American policymakers and cause harm to the outside world. The envy of “American Primacy” is of secondary importance.

This study aims to investigate the decline of American hegemony as one of the most prominent crises of the modern world order, from a broader perspective that transcends narrow traditional interpretations. The paper assumes that the September 11 events in 2001 have launched the actual decline in American hegemony. Tracing the evolution of US global strategy over the past two decades, the study seeks to analyze the main causes and repercussions of the decline of US hegemony, which would provide a bird’s eye view of what the current global system is going through.

The study investigates the decline in American hegemony through a longitudinal within-case analysis which focuses on the causal path of decline in hegemony in the case of the USA, since the events of September 11, 2001, and tries to identify the causal mechanisms behind this decline. Following George and Bennet (2005), the study uses process tracing to examine its research question. Process-tracing method seeks to identify the intervening causal process – causal chain or causal mechanisms or the steps in a causal process – that leads to the outcome of a particular case in a specific historical context (Mahoney, 2000; Bennet and Elman, 2006). The study chose this method, as it offers more potential for identifying causal mechanisms and theory testing (George and Bennet, 2005); it opted for a specific procedure, among the variety of process-tracing procedures listed by George and Bennet, which is the detailed narrative presented as a chronicle, accompanied by explicit causal hypotheses. Using this process tracing procedure, the study assumes that American hegemony has witnessed dramatic changes in the aftermath of critical junctures, particularly the events of September 11, 2001, and the financial crises, 2008, which contributed significantly to this decline. Consequently, it traces the impact of these events on the state of American hegemony, in light of the review of contributions of different theories on hegemony in the field of international relations, both traditional and critical. Consequently, introducing the theoretical framework used in the study (the four-dimensional model of hegemony), which transcends criticisms of previous theories.

The crises of the modern world order and the decline of American hegemony – being the main manifestation of such crises – revealed the inability of the traditional and critical approaches reviewed in the study to interpret this decline and those crises. The reason behind that was the inability of these interpretations to reflect the various dimensions of American hegemony and its decline since the September 11 events. This highlights the importance of using the four-dimensional model, which combines different factors in the analysis and has proved to be an appropriate model for studying the case of American hegemony and its decline after the events of September 11, as it deals with the phenomenon of hegemony as a social relationship based on specific social networks.

Despite the currency and relevance of the decline of US hegemony for both the academic and political world, the topic needed to be analyzed systemically and addressed in a thorough scientific way. Through the application of theoretical concepts into the analysis of empirical data, this study contributes to a field where too often the discourse about decline of American hegemony is led without the required theoretical or conceptual considerations.
