Logistics Capabilities

Electric vertical takeoff and landing (eVTOL) aircraft technology has developed beyond the traditional aviation industry and now influences the creation of new and novel transportation applications. Some experts even suggest on-demand eVTOL logistics capabilities could be harnessed by crisis response teams to c ombat a future pandemic. The lessons of the COVID-19 crisis highlighted the challenges of managing a global pandemic response due to the difference in regional and local resources, culture, and political systems. Although there may not be a uniform crisis management strategy that the world can agree on, next-generation vertical flight vehicles could be used to distribute limited medical equipment, supplies, and personnel to hot spots faster than conventional aircraft or ground vehicles. However, creating this capability is not easy. This SAE EDGE™ Research Report by Johnny Doo addresses the opportunities and challenges of establishing an eVTOL fleet, including deployment, supporting infrastructure, and fleet management.

The Stability

The purpose of this study is to explore the stability and interaction between parental pressure and social research report, as well as the role of employment status and family income levels in this process. This study used a special study on Korean children (PSKC) 2–4 waves. Use t-test, correlation and autoregressive cross-delay modeling to analyze the data. The main findings of this study are: First, over time, parental pressure and mother’s social research report are consistent. Secondly, the pressure of motherhood and childcare has an obvious lagging effect on upbringing, and vice versa. Third, there is no significant difference between working mothers and non-working mothers in terms of the stability of working parents' pressure, social research report and social research report for children's pressure channels. However, parental pressure can only predict the social research report of working mothers. Fourth, there is no significant difference between the stability and interaction of these two structures in household income levels. In short, the results show that, over time, parental pressure is consistent with mother’s social research report. The results also show that there is a significant cross-lag effect between the mothers’ perceptions of mutual pressure analysis. In the process from parental pressure to social research report, I found the difference between working and non-working mothers. The advantage of this study is that the expected longitudinal design was adopted during infancy and the priority between the two structures can be considered. The results of this study can be used as a source of intervention plans to help parents withstand severe parenting pressure and lack of social research report.

AbstractThis article is a research report involving three anthropological studies conducted during the period of “Kuige” and their “re-studies.” By narrating the project, I set forth my views on the connections and differences between Chinese anthropological explorations from two historical periods. These anthropological explorations refer to the study of Lu Village conducted by Fei Xiaotong, that of “West Town” (Xizhou) by Francis L. K. Hsu, and that of “Pai-IPai” (Dai) villages by Tien Ju-Kang. They were all completed in the late 1930s and early 1940s. Each writer extracted a framework to analyze the land system, ancestor worship, and the relationship between humans and gods from the writer’s own field experience. Despite the difference in research methods, all three studies noticed the cultural differences between rural society and modernity. Since 2000, Peking University and Yunnan Minzu University have launched a “Province-university Cooperation Project.” During the project, a research team formed of several young scholars revisited Lu Village, “West Town” (Xizhou), and Namu Village. These writers’ works were based on the data acquired in their fieldwork and drew upon the opinions raised by global anthropologists on “re-study” in recent decades. Considering the dual effects of social change and shifts in academic concepts around “follow-up research,” the scholars put forward several points of view with their ethnographies, which all featured the characteristics of inheritance and reflection. Based on the results of the three “re-studies,” this article emphasizes the importance of the study of public rituals for the research of rural society. This article also attempts to re-examine the methodology of “human ecology,” which profoundly impacts Chinese anthropology and sociology.

The aim of this paper is to assess the impact of the rivet hole sizing process on the fatigue life based on the example of the structural connections characteristic for riveted joints used in aviation industry. Test specimens reflected the structural connection consisting in a riveted lap joint of an airplane plating stiffened with a T-bar. Connected plates and the T-bar are made of D16CzATW aluminum alloy. 3 mm diameter oval head solid rivets for aviation-related purposes were made of PA24 aluminum. During fatigue tests, individual specimens with non-sized holes and with sized holes were subjected to uniaxial, one-sided, fixed-amplitude loading (R = 0). It can be concluded from the fatigue life comparison that introduction of an additional operation in the riveting process, i.e. the hole sizing, results in significant, about two-fold increase of the fatigue life of the riveted structural connection, even at slight sizing degree. The difference of the specimen damage nature was observed between specimens with sized and non-sized holes.

The Difference

The issue of national diversity is considered one of the most important points in studying the development of political systems in our time. Many scholars and researchers have noticed that there is rarely a people or nation in the world today that does not possess different national or ethnic diversity, some of which succeed in forcibly obliterating them, which leads to its ignition and the division of nations and states. (As happened in the Soviet Union, Yugoslavia, Czechoslovakia, the Eight State, the Empire of Austria-Hungary, etc.) and as it will happen in the future in other repressive countries, no matter how long their repression takes, and some of them succeed in preserving them through assimilation and understanding, as happened in Switzerland and a few other countries. While there are countries that have been striving for decades to arrange their national situations (such as India, Belgium and Spain), with varying degrees of success. The element of national diversity sometimes plays an active role in reforming the political system, and at other times this national diversity hinders the entire political reform. On the basis of the difference and contrast between the two models in terms of the degree of modernity and development, however, a careful examination of the two models confirms that they are not different to this degree. Only years (1998 in Britain and 2003 in Iraq) and the political conflict still exists in the two countries, leading to a final solution to this crisis.

Social media has been in our lives so much lately that it is an undeniable fact that global pandemics, which constitute an important part of our lives, are also affected by these networks and that they exist in these networks and share the users. The purpose of making this hashtag analysis is to reveal the difference in discourse and language while analyzing Twitter data and to evaluate the effects of a global pandemic crisis on language, message, and crisis management with social media data. This form of analysis is typically completed through amassing textual content data then investigating the “sentiment” conveyed. Within the scope of the study, 11,300 Twitter messages posted with the #stayhome hashtag between 30 May 2020 and 6 June 2020 were examined. The impact and reliability of social media in disaster management could be questioned by carrying out a content analysis based totally on the semantic analysis of the messages given on the Twitter posts with the phrases and frequencies used.

This research is an extension of our previous work [Debnath and Srivastava (2021)]. In that paper, we designed a portfolio based on data taken from National Stock Exchange (NSE), India, during 1 January 2020 to 31 December 2020 and performance of that portfolio in real-life situation was examined during 1 January 2021 to 21 May 2021 assuming investments were made according to the proposed model. We observed that our proposed portfolio was efficient enough in that period to beat the performance of most of the in-demand mutual funds. It was also conjectured that this portfolio would be sustainable post the second wave of COVID-19 in India. In the present paper, our aim is to validate this conjecture. Here, we examine the performance of this portfolio during the period 1 January 2021 to 18 October 2021 using the same previous data set. We also investigate the performance of this portfolio if it was blindly adopted without applying the stock selection methodology during 1 January 2019 to 31 December 2019. Using paired t-test between the difference of means of the performances in the year 2019 and the year 2021, we show that the performance in 2021 was significantly enhanced because of selecting the stocks applying our proposed model.

The present global pandemic of covid 19 requires many psychotherapists to work at a distance via telephone or the internet. At the same time a considerable number of psychotherapists work with masks while maintaining social distance. This pandemic impact draws our attention to two questions: One is the difference of working within the office vs. working online. Two is how external events impact the individuals socially as well as personally. This chapter explores clinical cases where, even though Covid and its implications imposed a horrible loss and increasing day to day unpredictability on the therapeutic space, the focus of therapy was readjusted thus igniting a process of deeper self-understanding.

Both Britain and Japan have made reservations and continuations to the monarchy in the process of historical development, and their political systems are constitutional monarchy. The royal family of both countries has a very long history. With the historical development and social change, the monarch has become a spiritual and cultural symbol. The “sanctification” of the monarch and the strong “plot of the monarch” have been deeply rooted in social culture. From the perspective of historical development and social and cultural influence, although there are similarities between the royals of the two countries, their roles in political, economic and social stability are different from the ways in which they are exerted. Through the comparison between Britain and Japanese monarchy in the above three aspects, this paper analyzes the difference between the two countries monarchy in the size of the role, the way to implement the role and the impact, and finally compares and summarizes the role of the two countries monarchy.

The Difference

In New Zealand, housing is typically low density, with light timber framing being the dominant form of construction with more than 90% of the market. From 2020, as a result of the global pandemic, there was a shortage of timber in New Zealand, resulting in increased popularity for light steel framing, the main alternative to timber for housing. At the same time, the New Zealand government is committed to sustainability practises through legislation and frameworks, such as the reduction of whole-of-life carbon emissions for the building industry. New Zealand recently announced reducing its net greenhouse gas emissions by 50% within 2030. Life cycle assessment (LCA) is a technique for assessing the environmental aspects associated with a product over its life cycle. Despite the popularity of LCA in the construction industry of New Zealand, prior research results seem varied. There is no unified NZ context database to perform an LCA for buildings. Therefore, in this paper, a comprehensive study using LCA was conducted to quantify and compare the quantity of carbon emissions from two commonly designed houses in the Auckland region, one built from light timber and the other from light steel, both designed for a lifespan of 90 years. The cradle-to-cradle system boundary was used for the LCA. From the results of this study, it was found that the light steel house had 12.3% more carbon in total (including embodied and operational carbons) when compared to the light timber house, of which the manufacturing of two houses had a difference of 50.4% in terms of carbon emissions. However, when the end-of-life (EOL) analysis was included, it was found that the extra carbon could be offset due to the steel’s recyclability, reducing the amount of embodied carbon in the manufacturing process. Therefore, there was no significant difference in carbon emissions between the light steel and the light timber building, with the difference being only 12.3%.

The conclusion first assesses the prime ministers against the criteria set out in the introduction: their longevity, their control over their parties, and their ability to shape the agenda. The first two can provide evidence of those who were successful. Noticeably those who brought their party from opposition to government were those who were likely to flourish. Second, the conclusion explores the difference between the four political systems and the impact they have on the working of the prime ministers. It identifies the variations in cabinet practices and the degree to which cabinet remains a consistent decision-making forum in Australia and New Zealand but less so in Britain and Canada. It concludes by stressing that much of the difference can be explained by the levels of accountability prime ministers have to their parliamentary colleagues, rather than a broader party electorate: a choice between competing principles of party democracy and accountability.
