This chapter explores the relationship between music and physical gesture, drawing on recent research on the spontaneous gestures that accompany speech. Such gestures appear to be motivated by thought processes that are independent from speech and that in many cases offer analogs for dynamic processes. The chapter outlines the infrastructure for human communication that supports language and gesture as well as music. This outline provides a framework for exploring how music and gesture are similar and for how they are different. These comparisons are made through analyses of the movements Fred Astaire makes while accompanying himself at the piano in the 1936 film Swing Time and those Charlie Chaplin makes to Brahms’s Hungarian Dance No. 5 in the 1941 film The Great Dictator. These analyses further explicate the role of syntactic processes and syntactic layers in musical grammar and introduce referential frameworks, which serve as perceptual anchors for syntactic processes.

The chapter discusses the relationship between social movements and peaceful change. First, it reviews the way this relationship has been elaborated in IR constructivist and critical analyses, as part of transnational activist networks, global civil society, and transnational social movements, while considering the blind sides left by the dominant treatment of these entities as positive moral actors. Second, the chapter reviews insights from the revolution and political violence literature, a literature usually sidelined in IR debates about civil society, in order to cast a wider relational perspective on how social movements participate in, and are affected by, interactive dynamic processes that may escalate into violent outcomes at both local and international levels.

This paper focuses on the problem of the governance of industrial districts in Italy. The analysis begins with an assessment of the dynamic processes that characterize the development of industrial districts, particularly as concerns the elements of a cultural nature. The relationship between local political attitudes and forms of local growth is considered, generally revealing how in the various practical examples there is a convergence between models of political behavior and the needs of the system of small enterprises. The paper ends with a brief discussion of the law 317/91, designed to establish the responsibilities and roles of the industrial districts.

Many qualitative studies about the exchange of sex for money, drugs, and less tangible outcomes (i.e., social status) contend that this activity contributes to high levels of internalized stigma among people in sex work. The cis (n = 33) and trans people (n = 5) who participated in our project about health, violence, and social services acknowledged the stigma associated with sex work but were not governed by the dominant discourse about its moral stain. They shared nuanced insights about the relationship between sex work and self-respect as people who use their earnings to mitigate the struggles of poverty and ongoing drug use, and care for themselves more broadly. This study sheds new light on the ways that cis and trans people negotiate issues of money, agency, and self-care, contributing to the literature on consensual sex work that examines different aspects of stigma, safety, and health with a nuanced, non-binary gender analysis.

The complexes [cation] [Hg(SR)3](R = Me, cation = Et4N+; R = But, cation = Et4N+, Bu4N+, [N(Ph3P)2]+) have been prepared. The crystal structure of the methanethiolate complex shows that it contains centrosymmetric dinuclear anions [(MeS)2Hg(�-SMe)2Hg(SMe)2]2- with distorted tetrahedral geometry about the mercury atoms. Vibrational spectroscopic evidence suggests that this complex dissociates on dissolution in ethanol to give mononuclear [Hg(SMe)3]- species. The ButS- complexes appear to exist as mononuclear [Hg(SBut)3]- species both in the solid state and in solution. The metal-sulfur stretching frequencies are assigned for all of the complexes studied, and the vibrational spectra are discussed in terms of the structures of the complex anions involved. Crystal data for [(C2H5)4N]2Hg2(SCH3)6 : a 8.656(5), b gS130(6), c 12.368(8) �; α 102.16(4), β 105.51(4), γ 105.29(4)�; space group P1, Z 1, R 0.034, Rw 0.042.

Atomistic analysis of the ion transport in polymer electrolytes for all-solid-state Li-ion batteries was performed using molecular dynamics simulations to investigate the relationship between Li-ion transport and polymer morphology. Polyethylene oxide (PEO) and poly(diethylene oxide-alt-oxymethylene), P(2EO-MO), were used as the electrolyte materials, and the effects of salt concentrations and polymer types on the ion transport properties were explored. The size and number of LiTFSI clusters were found to increase with increasing salt concentrations, leading to a decrease in ion diffusivity at high salt concentrations. The Li-ion transport mechanisms were further analyzed by calculating the inter/intra-hopping rate and distance at various ion concentrations in PEO and P(2EO-MO) polymers. While the balance between the rate and distance of inter-hopping was comparable for both PEO and P(2EO-MO), the intra-hopping rate and distance were found to be higher in PEO than in P(2EO-MO), leading to a higher diffusivity in PEO. The results of this study provide insights into the correlation between the nanoscopic structures of ion solvation and the dynamics of Li-ion transport in polymer electrolytes.

The chapter examines the relationship between orthography, phonology, and morphology in Turkish and what this means for Turkish-English bilingual language processing. Turkish offers a unique language medium in pitching theoretical perspectives both in linguistics and psycholinguistics against each other because of its properties. Empirical and theoretical considerations are employed from both domains in order to shed light on some of the current challenges. In line with contemporary thought, this chapter is written with the view that bilingual speakers engage a singular language or lexical system characterized by fluid and dynamic processes. Particular focus will be given to English-Turkish speaking bilinguals in the UK, which includes heritage (HL) and non-heritage language speakers. Evidence from monolingual developmental research as well as neuropsychology will be examined to confirm findings of previous studies in other European contexts, and also to raise attention to various challenges which need to be addressed across all contexts.
