After a thousand years of feudal middle ages, the west entered a new era, namely the Renaissance, from the 14th century. With the influence of humanism on the cultural field, people's individuality consciousness has been released. Western pop music is a western art form with profound connotation and eternal value. In recent years, many scholars and music educators have carried out a series of research and popularization of western pop music. Through scientific methods, the students' ability to control pop music can be transformed into the basic quality of solfeggio listening training, so as to achieve the combination of the advantages of pop music and serious music, so as to complete the interactive, concise and diversified solfeggio teaching and broaden new teaching ideas. The role and influence of religious songs on the development of western vocal music art is incalculable. Its value is reflected in various fields of vocal music art. Therefore, while singing and appreciating religious songs, we should also strengthen the study and research of their background and historical development.

AbstractThis insight piece features the Crisis Communication Think Tank (CCTT) at the University of Georgia in the United States. As a thought leadership entity joined by leading practitioners and scholars, the CCTT aims to build academia‐industry collaborations through dialogue on emerging topics and cocreation of evidence‐based advice for next‐generation crisis management theory and practice. This case study, written by the CCTT director and cofounder, walks through the origins of the CCTT, its mission and goals, structure and focus areas, as well as core activities and outputs. It discusses the unique value the CCTT approach brings to cross‐sector crisis communication knowledge generation and dissemination, shedding new light to centre‐based model exploration and innovative crisis management thought leadership development.

Sea level rise is a serious situation facing coastal cities in the world. In the United States, Miami is one of the most vulnerable cities as far as sea level rise is concerned. Floods in Miami not only come from high seawater but also from inland rivers and frequent storm surges. With Miami as a target city, this paper was prepared after taking care of its current political, economic, and cultural status, aiming to explore the way in which Miami responds to rising sea levels and proposes future urban visions. The new solution may also be applied partially or completely in other coastal cities. This work is divided into three phases. The first phase is an in-depth study that involves four aspects of Miami. They are the Water Environment (the origin and causes of the floods in Miami and existing largescale solutions), Ecological Environment (main existing plant and animal species in Miami, species differences in coastal and inland areas, and ecological migration caused by seawater intrusion), Humanistic Environment (Miami's demographic composition and cultural composition, as well as the history of migration) and Urban Infrastructure (Miami's infrastructure, existing public transportation, water supply and drainage systems, green infrastructure with proper measures and defects in response to floods and deficiencies) . The second phase proposes the concept of future assumptions for urban infrastructure. The concept is mainly based on the study in the first phase, as well as the famous case about the future of the city in history, which may be applied to Miami's unique geographical and cultural background. Due to the high permeability of the foundations in the city, the ordinary sea-crossing dams cannot effectively block seawater. That means the low-lying areas are difficult to retain in the next 50 years. The future vision proposed in this paper is to establish a series of infrastructure conversion centers, including the underground regional water treatment center and the elevated traffic conversion center. The lowland city will become the city of water in the future, and the "infrastructure center" will provide the transfer and berthing of waterborne vehicles, amphibious vehicles and land vehicles, all being connected via elevated viaducts and light rails. The third phase is the in-depth study and design of the concept. First of all, it is determined that the newly-built infrastructure conversion center is located at the site of the urban backbone road network in order to connect existing urban fabrics and roads. Then the population of each block and the frequency of flood disasters are analyzed. According to different needs, the conversion centers with different functions and sizes are designed, each placed in the existing city map. The final part of the design is the plan for the construction, that is, the construction progress that the government can control at different times.

This study examined the perceived crisis preparedness of a random sample of public relations practitioners in the United States (N=144) as evidenced in their assessment of crisis situation and organizational resources. The main effects of organization size and practitioner role were evident on practitioner's perceived crisis preparedness in different crisis situations. Organization type was found to be effective only when it interplayed with either practitioner role or organization size.

Two lot‐sizing heuristics are proposed for deterministic time‐varying demands, a case commonly encountered in requirements planning systems. The first heuristic simplifies the stopping rule of the Silver‐Meal (SM) heuristic so that difficult cases may be solved nearly optimally. The second combines the merits of both the SM and the Least‐Unit‐Cost heuristic Both perform favourably even when compared to recent modifications to the basic SM algorithm.

Abstract'When people's emotions are at stake, there is the constant need to be seen to engage and connect with them in their hours of need'. This study contributes to the literature on Integrated Crisis Mapping, a stakeholder‐centric crisis communication framework that attunes organisational leaders to the emotional responses and coping needs of their primary publics. Building on Weick's insight about the importance of an attitude of wisdom in making sense of a crisis, the study proposes crisis attitude as a keystone concept to help bridge the gap between theory and practice in crisis communication. The study illustrates the concept with an attitude of humility, explaining how it could be apposite to navigating the dynamics of a crisis and serve a sensegiving function that decreases stakeholders' negative emotions and fosters their trust in leadership.

Along with the advance of technologies and evolving variety of military missions, Edge Organization has been proposed to transform C2 from its conventional hierarchical and inflexible structures into more network centric and flexible forms. To develop a better understanding of Edge Organizations, in our research we take a dynamical and adaptive complex systems approach to exploring dynamical features of Egde Organizations and investigate how networking structures, self-organization mechanisms may impact on the entropy of Edge Organizations and consequently determine their agility and performance. After defining the basic concepts, we introduce an agent-based simulation model that captures the interplay among networking structures, self-organization mechanisms, and organization agility and performance with entropy as an intermediate variable. Through simulation-based case studies using the proposed model, important dynaical features of Edge Organizations can be clarified and conditions for avoiding high entropy equilibirums and for acheiving high level of agility be identified. In addition to the description of the proposed model, various measures of organizational entropy and organizational agility are discussed. A scenario design for future simulation studies is presented.
