This paper aims to investigate the different analytical methods used to predict the performance of seaplanes to define the weaknesses in each method and be able to extend the analytical approach to include the nonlinear terms (unsteadiness).

First, the elemental hydrodynamic characteristics of seaplanes are discussed. Second, five different analytical methods are reviewed. The advantages and disadvantages of each method are stated. After that, the heave and pitch equations of seaplane motion are illustrated. The procedure of obtaining the solution of the heave and pitch equations of seaplane motion is explained. Finally, the results obtained from the most common methods are compared.

The results show that the methods are based on different assumptions and considerations. As a result, no method is optimal for all types of seaplanes. Moreover, some of the analytical methods do not study the stability of the seaplane, which is a major issue in the design of seaplanes. In addition, all methods consider the motion as steady and linear. The objective is to extend the work to include the nonlinear effects.

This paper presents some of the analytical methods used in describing the performance of seaplanes and explains how can they be applied. Moreover, it summarises the advantages and disadvantages of each method.

We explore how, and how accurately, people assess their influence over others’ behavior and attitudes. We describe the process by which a person would determine whether he or she was responsible for changing someone else’s behavior or attitude, and the perceptual, motivational, and cognitive factors that are likely to impact whether an influencer’s claims of responsibility are excessive, insufficient, or accurate.

We first review classic work on social influence, responsibility or blame attribution, and perceptions of control, identifying a gap in the literature with respect to understanding how people judge their own responsibility for other people’s behavior and attitudes. We then draw from a wide range of social psychological research to propose a model of how an individual would determine his or her degree of responsibility for someone else’s behavior or attitude.

A potential influencer’s beliefs about the extent of his or her influence can determine whether he or she engages in an influence attempt, how he or she engages in such an attempt, and whether he or she takes responsibility for another person’s behavior or beliefs.

For decades, scholars researching social influence have explored how one’s behavior and attitudes are shaped by one’s social environment. However, amidst this focus on the perspective of the target of social influence, the perspective of the influencer has been ignored. This paper addresses the largely neglected question of how much responsibility influencers take for the impact their words, actions, and presence have on others.

After the collapse of the USSR, Eurasian integration projects, proposed by Russia, Kazakhstan and Turkey, began to develop in the post-Soviet space. Hence, there is growing interest in Eurasianism as an ideology. In this context, the study of the use of the Eurasianism's ideas in practice becomes relevant. The argument of this article is that Russia, Turkey, and Kazakstan have their own interpretations of Eurasianism's ideas to develop the ideological basis of their own integration projects. The purpose of the article is to answer the question: How is the Eurasianism used in integration projects of Russia, Turkey and Kazakstan?

The concept of Eurasianism has been viewed in terms of constructivism. On the basis of the principles of social constructivism, and in particular the works of constructivist ideologue Alexander Wendt, a comparative analysis was made. The ideas of Eurasianism in the integration processes of Russia, Kazakhstan and Turkey has been carried out based on the criteria such as the role of common ideas, identity, consciousness, memory and culture. The examples of mentioned countries were compared, to consider the development of the ideas of Eurasianism in practice.

The ideas of Eurasianism have a significant impact on the integration processes of the post-Soviet space. Eurasianism advocates for important factors such as respect for cultural and civilizational differences between different nations, their equality in the overall union and common development opportunities. Such factors are undoubtedly important for the success of integration projects. The reflection of many individual thoughts of classical Eurasians and Neo-Eurasians can be seen in the statements of various ministers and leaders of Russia, Kazakhstan and Turkey. The initiatives of these countries in creating integration projects also show the influence of the Eurasian concept.

In the 1990s, the study of Eurasianism gained new significance in academic circles. Articles and periodicals devoted to this concept were published. However, all parallels between variations in concepts of Eurasianism have been conducted on a theoretical level. The importance of this article lies in the fact that conceptual differences are compared in practice. Researchers had not previously considered the study of the relevance and productivity of Eurasianism in practice by comparing examples and experiences from different countries. The novelty of this article lies in its attempt to solve this problem.

The ecological environment of the Loess Plateau, China, is extremely fragile under the context of global warming. Over the past two decades, the vegetation of the Loess Plateau has undergone great changes. This paper aims to clarify the response mechanisms of vegetation to climate change, to provide support for the restoration and environmental treatment of vegetation on the Loess Plateau.

The Savitsky–Golay (S-G) filtering algorithm was used to reconstruct time series of moderate resolution imaging spectroradiometer (MODIS) 13A2 data. Combined with trend analysis and partial correlation analysis, the influence of climate change on the phenology and enhanced vegetation index (EVI) during the growing season was described.

The S-G filtering algorithm is suitable for EVI reconstruction of the Loess Plateau. The date of start of growing season was found to gradually later along the Southeast–Northwest direction, whereas the date of the end of the growing season showed the opposite pattern and the length of the growing season gradually shortened. Vegetation EVI values decreased gradually from Southeast to Northwest. Vegetation changed significantly and showed clear differentiation according to different topographic factors. Vegetation correlated positively with precipitation from April to July and with temperature from August to November.

This study provides technical support for ecological environmental assessment, restoration of regional vegetation coverage and environmental governance of the Loess Plateau over the past two decades. It also provides theoretical support for the prediction model of vegetation phenology changes based on remote sensing data.

Organizations desire more accurate cost systems as competition increases, and consequently increase cost system complexity, as cost systems with greater complexity are potentially more accurate than simpler systems. However, even complex systems are prone to impactful inaccuracies, for example, due to design or calculation issues, that can adversely affect decision-making and firm performance. The authors investigate whether and the extent to which cost system complexity and competition decrease managers’ attribution of cost-system-driven adverse firm effects to the cost system. The authors find greater cost system complexity (by inspiring greater confidence in the cost system) and higher competition (by providing a plausible external cause) decrease managers’ attribution of cost-system-driven adverse firm effects to the cost system. With both greater cost system complexity and higher competition, managers observing signals of material cost inaccuracies are potentially the least likely to attribute cost-system-driven adverse firm effects to the cost system.

Little attention has been given to the mental and physical health impacts of COVID-19 on the academic public health workforce. Academic public health is an important support mechanism for public health practice, providing expertise and workforce training, conducting research, disseminating evidence-based scientific information to both public health and lay audiences, and serving as a supplementary workforce when additional resources are needed. These roles become more important during a public health emergency, particularly during a prolonged public health crisis like the COVID-19 pandemic. As a result of the COVID-19 response, the roles of academic public health have expanded to include developing and implementing contact tracing, surveillance, testing, and vaccination programs for universities and their surrounding communities, all while continuing to prepare students and support the public health practice workforce in their ongoing efforts. As in other responder groups, this has resulted in significant mental health effects and burnout among public health academicians. The authors suggest important steps that can be taken to improve the resilience of the academic public health workforce and to support their contributions during prolonged public health emergencies.

Group members often reason egocentrically, both when allocating responsibility for collective endeavors and when assessing the fairness of group outcomes. These self-centered judgments are reduced when participants consider their other group members individually or actively adopt their perspectives. However, reducing an egocentric focus through perspective taking may also invoke cynical theories about how others will behave, particularly in competitive contexts. Expecting more selfish behavior from other group members may result in more self-interested behavior from the perspective takers themselves. This suggests that one common approach to conflict resolution between and within groups can have unfortunate consequences on actual behavior.

This chapter describes the business goals, purpose, and strategy of public defense and military services. It reinforces defense and military organizations’ fundamental bureaucratic administrative culture (Tier 1). The authors describe the influence that political appointees as leaders may play in shaping public sector cultures. The bureaucratic culture of diplomacy is deconstructed, and each of the five layers is described in detail. Additionally, the authors explain why focusing on the beliefs layer is the dominant layer and the essential starting point for analysis in military cultures. The public service culture (Tier 2) is a mediating and grounding culture for the military. It is firmly grounded in the foundational values of the state. The chapter outlines the landscape of external influencing cultures (Tier 3) in the defense and military landscape. Finally, the potential value and challenges of developing internal knowledge, learning, and collaboration (KLC) cultures are explored.

Role-taking, perspective taking, and empathy have developed through parallel literatures in sociology and psychology. All three concepts address the ways that people attune the self to others’ thoughts and feelings. Despite conceptual and operational overlap, researchers have yet to synthesize existing research across the three concepts. We undertake the task of theoretical synthesis, constructing a model in which role-taking emerges as a multidimensional process that includes perspective taking and empathy as component parts.

We review the literatures on role-taking, perspective taking, and empathy across disciplines. Focusing on definitions, measures, and interventions, we discern how the concepts overlap, how they are distinct, and how they work together in theoretically meaningful ways.

The review identifies two key axes on which each concept varies: the relative roles of affect and cognition, and the relative emphasis on self and structure. The review highlights the cognitive nature of perspective taking, the affective nature of empathy, and the structural nature of role-taking. In a move toward theoretical synthesis, we propose a definition that centers role-taking as a sociological construct, with perspective taking and empathy representing cognition and affect, respectively.

Role-taking is an important part of selfhood and community social life. It is a skill that varies in patterned ways, including along lines of status and power. Theoretical synthesis clarifies the process of role-taking and fosters the construction of effective interventions aimed at equalizing role-taking in interpersonal interaction.

Accounting practitioners and educators agree that effective oral and written communication skills are essential to success in the accounting profession. Despite numerous initiatives to improve accounting majors’ communication skills, many students remain deficient in this area. Communication literature suggests that one factor rendering these initiatives ineffective is communication apprehension (CA). There is general agreement that accounting students around the globe have higher levels of CA than other majors. Therefore, accounting educators interested in improving students’ communication skills need to be aware of the dimensions and implications of CA. This chapter provides a review of the relevant literature on CA, with a focus on CA in accounting majors. It also presents intervention techniques for use in the classroom and makes suggestions for future research.
