Nature-based solutions (NBS) generate different impacts at the urban scale, such as the ability to regulate water or store carbon, comparable to traditional, gray infrastructures in a more cost-efficient way. On the other hand, by their intrinsic nature, NBS do deliver a series of other services that are commonly defined as social, economic, and environmental cobenefits. These benefits are not always valued in a consistent and complete way, so there is the need to compile a more comprehensive evidence base on the social, economic, and environmental effectiveness of NBS. The chapter attempts to identify a categorization of the existing NBS and define the ecosystem services (ES) provided by them. Furthermore, starting from the results achieved through the definition of the existing NBS frameworks assessment, the chapter will identify a set of key performance indicators KPIs, based on the ES produced by NBS, to measure the economic, social, and environmental benefits generated in by NBS at the urban level taking into account their multifunctional character. In total, 66 key performance indicators have been individuated: 3 for provisioning services, 38 for regulating services, 17 for cultural services, and 8 for supporting services. Each indicator has been associated to a category of ES in order to measure and evaluate the performances of NBS implemented in cities.

The purpose of this paper is to analyze the fat, saturated fatty acid and trans fatty acid contents in ready-to-eat foods distributed at amusement parks to develop an appropriate food safety management system for children.

In all, 322 ready-to-eat food samples categorized into 17 types were collected from nine Korean amusement parks and their fat, saturated fatty acid and trans fatty acid contents were assessed.

Fat, saturated fatty acid and trans fatty acid contents were relatively high in flour-based products. On the basis of the Korea Food and Drug Administration classification, the samples in 12 categories were classified as high-fat foods. The samples in nine categories were classified as high-saturated fatty acid foods. Most samples also contained non-negligible levels of trans fatty acids. The fat, saturated fatty acid and trans fatty acid contents of samples even in the same category varied markedly.

This research will inform the necessity of an appropriate safety management system for ready-to-eat foods distributed at amusement.

Although the fat contents of foods distributed around school area were often observed, the potential risk of those in ready-to-eat foods distributed at amusement parks have rarely been assessed. As patterns of food intakes vary world-widely, a periodic monitoring data like this study may be useful for international organizations and researchers.

Historically Black colleges and universities (HBCUs) and Black Greek-lettered organizations (BGLOs) are institutions and organizations that provided African Americans with options for unification and education during years of overt racial discrimination when education and socioeconomic comforts were limited for the vast majority of Americans of African descent, and they continue to serve as support structures for African Americans today. Nevertheless, in the “postracial” era of accountability, questions surrounding the relevance of these organizations have become common discourse. While these organizations face similar narratives, HBCU and BGLO research, successes, and issues have not yet been analyzed, synthesized, or even acknowledged in significant ways. Thus, the purpose of this chapter is to promote the need for research and scholarship that explores and highlights the parallels and intersections of today’s HBCUs and BGLOs through a review literature on BGLOs and educational outcomes.

International assessment data consistently indicate that when compared to their peers from other major developed nations, American students, irrespective of their race, underperform in reading and mathematics (Darling Hammond, 2010; NCES, 2011; PIRLS, 2011; PISA, 2009; TIMSS, 2011). Within an American context, African American males generally have the lowest reading scores as compared to their White peers (Husband, 2012; NCES, 2011; Schott Foundation, 2010; Spellings Report, 2006). Existing research indicates that these disparities in academic performance are a result of inequalities in access to quality education and differences in the treatment of students, which are deeply imbedded in historical patterns of racial, gendered, and class discrimination. However, past studies also indicate that these same students optimize their learning experiences and become high performers when they receive high quality instruction and school enrichments. Thus, this chapter examines the use of Readers Theater as an instructional model that may help to enhance the school achievement of student groups, such as African American males. The chapter documents the challenges that Black males face in schools and proposes performing arts education as a mediating mechanism and reading enhancement tool. Additionally, it includes an in-depth description of Readers Theater and examines several studies on this instructional method and its potential impact on African American males and their reading skills.

Circular economy (CE) has gained the attention of the business community with the promise of several trillions of dollars to be gained from finding productive uses for waste materials, and developing new business models focused on extending and reimagining the useful life of products. Industrial symbiosis (IS) involves the shared management of resources among multiple firms, most often within some geographic proximity. IS is particularly focused on the reuse of secondary materials, such as industrial by-products, for which conventional recycling does not exist. IS and CE represent a radical reconceptualization of business models from individual to collective competitive advantage with private and public benefits. IS has been recognized as a novel strategy for businesses and regions interested in implementing the CE. In this chapter, we explore the conditions and circumstances in which IS could play a pivotal role in increasing circularity and sustainability in diverse supply networks.

This chapter presents an innovative learning opportunity for tourism students, International Tourism and Hospitality Academy at Sea, that has been in operation for the last 10 years. The program could render itself as a case study of Kolb’s experiential learning theory according to which knowledge is created by transforming experience. Its uniqueness and complexity lie in its diversity. This program has involved between 80 and 130 tourism students yearly from four to six institutions from different countries participating in new scholarly inputs by non-resident professors and instructors.

This study aims to investigate the current and future status of overseas halal food marketing and develops strategies for improving the competitiveness of Korean seafood companies in the global halal food market.

The research uses a case study approach and a semi-structured review of previously published data. Evidence collected from literature reviews, supported by research studies, anecdotal proof, personal reflection and experience is also used. It also considers the perspectives of various stakeholder groups in the global halal food supply chain.

The global halal food market is forecasted to reach US$1.914tn in 2021. At present, Korea holds a small share of this market. To enter the emerging Islamic market, there is a need to develop strategies. This study recommends the following main strategies to improve the competitiveness of Korean seafood companies in the halal food market: reduce mistrust by improving halal authentication and certification standards; understand consumer behavior and develop marketing strategies according to the respective country’s socioeconomic and geographic status; train industry employees and develop competitive halal seafood products; exploit the rising global influence of Hanryu; establish a halal logistics/supply chain and halal industrial parks; and promote digital marketing and tourism. Moreover, the government should also subsidize halal seafood development, as well as provide export and international trade insurances.

As the Muslim population continues to grow, the importance of global halal food marketing also increases. Therefore, strategies for improving the competitiveness of Korean seafood companies in the global halal food market need to be taken into account.

The problem of goal generation (teleogenesis) is addressed by the development of a system framework based upon the property of hemispheric lateralization of functions. Micro‐information structure is examined to establish the role of replication in molecular, cellular and functional interactions. From the framework presented, conditions are derived under which output functions can be related to the evolution of the dichotic system and the inverse mappings between the system components. The holographic communication form is examined both in relation to the invertability requirement of the Fourier series and the source of the periodicity for an incident signal.

The purpose of this paper is to formulate an algorithm for a novel damage‐coupled material law for crystalline polyethylene at finite inelastic strains followed by investigation of the influence of the aggregate representation and material parameters on the material response.

The constitutive equations are developed within the framework of continuum damage mechanics to describe crystal fragmentation caused by atomic debonding of the crystallographic planes. The material is assumed initially isotropic and homogeneous and is represented as an aggregate of randomly oriented crystals with an orthorhombic lattice. For the velocity gradient, an additive decomposition into symmetric and skew‐symmetric components is applied, where the skew‐symmetric part (spin) is decoupled from the lattice shear by means of a damage variable. Structural features such as lattice parameters and orientations, slip systems, and kinematic constraints are incorpo‐rated.

The proposed model is implemented to predict stress‐strain behaviour under uniaxial tension and damage accumulation and texture development at the different stages of deformation. In the numerical examples, the effects of the aggregate size, crystal orientations, and material parameters on the model estimates are analyzed.

The model used herein is a first attempt to analyze the influence of crystal fragmentation caused by the debonding of the crystallographic planes on the predicted mechanical behaviour and texture development of polyethylene prior to failure.
