Experimental studies have provided convincing evidence that food bioactive compounds (FBCs) have a positive biological impact on human health, exerting protective effects against non-communicable diseases (NCD) including cancer and cardiovascular (CVDs), metabolic, and neurodegenerative disorders (NDDs). These benefits have been associated with the presence of secondary metabolites, namely polyphenols, glucosinolates, carotenoids, terpenoids, alkaloids, saponins, vitamins, and fibres, among others, derived from their antioxidant, antiatherogenic, anti-inflammatory, antimicrobial, antithrombotic, cardioprotective, and vasodilator properties. Polyphenols as one of the most abundant classes of bioactive compounds present in plant-based foods emerge as a promising approach for the development of efficacious preventive agents against NCDs with reduced side effects. The aim of this review is to present comprehensive and deep insights into the potential of polyphenols, from their chemical structure classification and biosynthesis to preventive effects on NCDs, namely cancer, CVDs, and NDDS. The challenge of polyphenols bioavailability and bioaccessibility will be explored in addition to useful industrial and environmental applications. Advanced and emerging extraction techniques will be highlighted and the high-resolution analytical techniques used for FBCs characterization, identification, and quantification will be considered.

Researchers examining nationalistic conceptions of language learning argue that nationalist essentialism often shapes the way languages are taught by educators and understood by learners. While numerous studies focus on how frameworks informed by Critical Discourse Analysis (CDA) and intercultural education offer alternative approaches to national stereotyping, these studies tend to focus on theoretical approaches, teacher perspectives or innovative teaching and learning resources. The literature to date, however, does not provide case studies on student responses to activities designed by the teacher to open up the classroom with opportunities that move beyond essentialist representations. This article responds to the need for such scholarship and presents a case study involving a focus group with tertiary students in an Italian language and culture subject. It reveals some of the ways in which students enacted and reflected upon alternatives to nationalist essentialising as a result of language learning activities that had been informed by the discursive processes of CDA. The findings suggest that students demonstrated skills and attitudes such as curiosity, subjectivities and connections with broader social contexts. Some of the data also indicates student engagement in critical inquiry and their potential for social agency.

Abstract Research within security studies has struggled to determine whether infectious disease (ID) represents an existential threat to national and international security. With the emergence of SARS-CoV-2 (COVID-19), it is imperative to reexamine the relationship between ID and global security. This article addresses the specific threat to security from COVID-19, asking, “Is COVID-19 a threat to national and international security?” To investigate this question, this article uses two theoretical approaches: human security and biosecurity. It argues that COVID-19 is a threat to global security by the ontological crisis posed to individuals through human security theory and through high politics, as evidenced by biosecurity. By viewing security threats through the lens of the individual and the state, it becomes clear that ID should be considered an international security threat. This article examines the relevant literature and applies the theoretical framework to a case study analysis focused on the United States.

Computer simulation is a tool increasingly used by archaeologists to build theories about past human activity; however, simulation has had a limited role theorising about the relationship between past behaviours and the formation of observed patterning in the material record. This paper visits the argument for using simulation as a means of addressing the gap that exists between archaeological interpretations of past behaviours and their physical residues. It is argued that simulation is used for much the same reason that archaeologists use ethnographic or experimental studies, and that computational models can help to address some of the practical limitations of these approaches to record formation. A case study from arid Australia, examining the effects of episodic surface erosion on the visibility of the record, shows how simple, generative simulations, grounded in formational logic, can be used to compare different explanatory mechanisms and suggest tests of the archaeological record itself.

This case study of a dispute over a project to construct a road through green space in a small Canadian city brings together two hitherto separate theoretical approaches to mobility disputes: "culture stories" and "regimes of engagement". The stories opponents tell, in interviews and documents, concern their mobilization against the project, the value of environmental preservation, and the costs of expanded automobility, culminating in contrasting visions of urban development. The culture stories approach examines how stories varied on a narrative dimension of informational formats, temporal structures, causal mechanisms, and plot institutionalization, and a place dimension of relational geography and physical attributes. The pragmatic conditions of the different narratives of contestation, and of the challenges faced by opponents are analysed in terms of the relation between regimes of engagement: a regime of familiarity based in slow mobilities, a regime of planned action based in automobility, and the clash of industrial and green orders of worth in a regime of justification

This paper examines the specifics of foreign policy strategies used by Denmark as a small state in the Arctic region. Based upon a number of theoretical approaches in terms of analyzing small state foreign policy, this study is primarily focused on how small states manage to pursue their goals in an international environment typically dominated by large powers.

This paper presents two experimental studies investigating the processing of presupposed content. Both studies employ the German additive particle auch (too). In the first study, participants were given a questionnaire containing bi-clausal, ambiguous sentences with 'auch' in the second clause. The presupposition introduced by auch was only satisfied on one of the two readings of the sentence, and this reading corresponded to a syntactically dispreferred parse of the sentence. The prospect of having the auch-presupposition satisfied made participants choose this syntactically dispreferred reading more frequently than in a control condition. The second study used the self-paced-reading paradigm and compared the reading times on clauses containing auch, which differed in whether the presupposition of auch was satisfied or not. Participants read the clause more slowly when the presupposition was not satisfied. It is argued that the two studies show that presuppositions play an important role in online sentence comprehension and affect the choice of syntactic analysis. Some theoretical implications of these findings for semantic theory and dynamic accounts of presuppositions as well as for theories of semantic processing are discussed.

Abstract The article attempts a brief overview and evaluation of the main theoretical approaches that have emerged in the study of cinematic intermediality in the last decades since intermediality has become an established research term in media studies. It distinguishes three major paradigms in theorizing intermedia phenomena and outlines some of the directions of change in the intermedial strategies of recent films. It identifies in contemporary cinema a tendency to add new dimensions to the relations of in-betweenness regarding both the connection of cinema to reality and its inter-art entanglements. Finally, the article describes a new type of intermediality, which integrates elements of trans-textuality, creating a format of expanded cinema within cinema. This strategy is presented in the context of Eastern European cinema through a short case study of Cristi Puiu’s film, Sieranevada (2016).

Corrections is a multi-layered business containing all aspects of life for the employees, clients/inmates, and the general public. Therefore, the findings of the study are transferable to many types of administrators. The chapter uses a case study approach and qualitative research methods. The study findings focuses on corrections administrative leadership mindset, philosophical approaches, and practice policies.. The conceptual and theoretical approaches included effective corrections administrators are promoting the growth of social capital (e.g., social skills and relationships), human capital (employable skills), and cultural capital (e.g., community and public safety). Four state prison wardens/administrators participated in this study. Data was collected via Creswell's in-depth portrait of cases: three-part series of semi-structured interviews. Four themes emerged during data analysis. This chapter focuses on the fourth theme and the conceptual framework.

This chapter examines how environmental concerns have influenced International Relations theory. It first provides a brief overview of the ecological crisis and the emergence of green theorizing in the social sciences and humanities in general, along with the status and impact of environmental issues and green thinking in IR theory. It then investigates green theory’s transnational turn and how it has become more global, while critical IR theory has become increasingly green. It also considers the different ways in which environmental issues have influenced the evolution of traditional IR theory. It concludes with a case study of climate change to illustrate the diversity of theoretical approaches, including the distinctiveness of green theories.
