We need theories that help us join the struggle for alternative futures. Cultural-historical approaches frame agency as something people do rather than something they have or sense. Building on this, I conceptualise agency in terms of the direction and reach of actions. Direction concerns movement from distinctive subject positionings towards desired endpoints. Reach concerns the extent of this movement. Direction and reach can be both outward (transforming the world) and inward (transforming the self). This acknowledges individuals’ contributions to changing their own lives and those of others without evacuating actions from the activities in which they are embedded. Motive, mediation, and motion are key to this. I illustrate these ideas in relation to existing research on young people’s environmental activism, a Latino boy in foster care, and a mother struggling to care for her infant child, as well as examples from prior research and other chapters in this volume.
Studies of agency are crucial if we are to grapple with pressing societal and environmental problems. Relevant conceptual and methodological solutions are needed to make alternative futures possible. This chapter outlines a broad position from which the subsequent contributions to this edited volume depart: one that recognises the urgency of agency and the value of cultural-historical perspectives in breaking away from problematic notions that frame agency as a matter of individuals pitted against the social, or in which individual actions lose their social contingency. Elaborating agency as a matter of struggle where individual and social are in dialectic relations, the chapter focusses on motives, mediation and motion. Within a broader and still-evolving cultural-historical framework, these motifs offer a distinctive way to deal with the challenges of conceptualising and facilitating agency, one which brings alternative futures into the realm of the possible by linking agency with learning and development.
This study aims to shed light on the motivation governing instrument choice. To collect data, we designed, piloted and administered a survey to a population of students enrolled in a music teacher education programme in Sweden. In line with previous, Anglo-centred research, we identify the instrument’s timbre and parental influences as relevant motives for this decision. Uncommonly, however, taking part in a testing session is suggested to have a similarly influential effect. Accordingly, our study supports the value of offering free-to-all sessions where children may try different instruments and openly discuss them with music teachers. Further insights from our results include families exerting more influence than peers, genre preferences bearing little relevance and potential tendencies regarding the influence of gender and socio-economic background for instrument choice. In addition, we uncover several motives that counteract this decision, music provision being the main impediment to pursuing one’s original preference, thereby underscoring the urgency of reducing the Swedish communal schools’ waiting lists for specific instruments. Our results further suggest the presence of mediating factors, including the musician’s starting age, family environment (beyond parents/guardians) and the availability of the instrument at home. This finding opens a new path in the study of instrument choice and challenges the way this topic has been traditionally researched, given that such factors could function as confounding variables in the study of instrument choice.
The author details her team’s research investigating sex differences in serial murder from an evolutionary perspective. Per Trivers’ (1972) Parental Investment Theory, evolved psychological mechanisms serve sex-specific interests to maximize reproductive fitness (genes represented in subsequent generations). As predicted, men – who produce millions of sperm daily and have an increased sex drive – commit serial murder primarily for sexual reasons. Women, who have limited reproductive opportunities compared to men, have evolved to place great importance on resources. As such, women commit serial murder primarily for monetary gain. Moreover, mirroring ancestral agrarian tendencies, male serial killers (MSKs) are hunters (stalkers) of victims, and female serial killers (FSKs) are gatherers of profit and “gather” victims in their immediate environment, including relatives. The author stresses that an evolutionary perspective (ultimate perspective) does not explain the entirety of serial murder. We must consider converging perspectives, including evolutionary, proximate biological, clinical, traumagenic, cultural, historical, social, and gender-role forces that contribute to the development and growth of the human psyche.
Matthias Koßler argues that Schopenhauer's theory of character is relevant to the recent revival of the concept in the social sciences. He argues that the theory of character Schopenhauer presented in his later essays is inconsistent with the theory developed in The World as Will and Representation. In the prize essays, Schopenhauer develops the Kantian distinction between intelligible and empirical character, treating the former as an innate, unchangeable metaphysical entity, while in WWR Schopenhauer clearly emphasizes the importance of empirical evidence, even for his metaphysics, so that intelligible character must be thought of in relation to experience. Furthermore, reason itself is an essential component of being human, and rationality involves the possibility of partly resisting the effect of a motive on the will, hindering it from achieving expression in action. Thus, human species character cannot just be a set of fixed properties, but rather a general field of possibilities by means of which we use our rationality to individualize ourselves. In conclusion, Koßler recommends avoiding the Kantian terminology of intelligible versus empirical character that achieves prominence in the prize essays. Instead, we should speak of a general concept of personhood that is necessarily specialized into an individual character.
This article is about Lehn–Lehn–Sorger–van Straten eightfolds $Z$ and their anti-symplectic involution $\iota$. When $Z$ is birational to the Hilbert scheme of points on a K3 surface, we give an explicit formula for the action of $\iota$ on the Chow group of $0$-cycles of $Z$. The formula is in agreement with the Bloch–Beilinson conjectures and has some non-trivial consequences for the Chow ring of the quotient.
We consider Calabi–Yau n-folds X arising from certain hyperplane arrangements. Using Fu–Vial’s theory of distinguished cycles for varieties with motive of abelian type, we show that the subring of the Chow ring of X generated by divisors, Chern classes and intersections of subvarieties of positive codimension injects into cohomology. We also prove Voisin’s conjecture for X, and Voevodsky’s smash-nilpotence conjecture for odd-dimensional X.
In this article we introduce the local versions of the Voevodsky category of motives with
$\mathbb{F} _p$
-coefficients over a field k, parametrized by finitely generated extensions of k. We introduce the so-called flexible fields, passage to which is conservative on motives. We demonstrate that, over flexible fields, the constructed local motivic categories are much simpler than the global one and more reminiscent of a topological counterpart. This provides handy ‘local’ invariants from which one can read motivic information. We compute the local motivic cohomology of a point for
$p=2$
and study the local Chow motivic category. We introduce local Chow groups and conjecture that over flexible fields these should coincide with Chow groups modulo numerical equivalence with
$\mathbb{F} _p$
-coefficients, which implies that local Chow motives coincide with numerical Chow motives. We prove this conjecture in various cases.
Prescription opioid misuse (POM) contributes to a larger opioid crisis in the US and Canada, with over 17 000 US POM-related overdose deaths in 2017. Our aims were to (1) identify specific profiles of respondents based on POM motives using the US National Survey on Drug Use and Health (NSDUH) and (2) compare profile respondents on sociodemographics, substance use and mental and physical health outcomes.
Methods
Analyses included 2017–18 NSDUH respondents with data on POM motives (n = 4810). POM was defined as prescription opioid use in a way not intended by the prescriber, including use without a prescription, in larger amounts or more frequently. Nine POM motives for the most recent episode were assessed, including ‘to relieve physical pain’ and ‘to get high’. Latent classes, based on POM motives, were estimated. Classes were compared on sociodemographics, substance use and physical and mental health outcomes.
Results
Eight latent classes were identified (in order of prevalence): pain relief only, relax-pain relief, sleep-pain relief, multi-motive, high, experimenter, emotional coping and dependent/hooked. Compared to the pain relief only group, the high and multi-motive classes had higher odds of all substance use outcomes, with the dependent/hooked class having higher odds on all but one outcome. Six of the eight classes had higher odds of past-year mental health treatment and suicidal ideation than the pain relief only class.
Conclusions
Screening for pain, pain conditions, problematic substance use and psychopathology are recommended in those with any POM. While those in the dependent/hooked, multi-motive and emotional coping classes are most likely to have prescription opioid use disorder (OUD), screening for OUD symptoms in all individuals with POM is also warranted.
Expands on aspects of ‘technical sociability’, which is underpinned by principles of reciprocity and periodicity, both involving forms of binary organization. These include what I dub the gracious riposte, a recurring behavioural pattern in which assertive and conciliatory gestures are juxtaposed. The commonly applied language model, involving the interpretation of music as ‘conversational’, is reviewed, and I also discuss the rise of the sharply memorable musical motive in the music of this time. This leads to a section on thematic interaction, whereby musical materials themselves, rather than players or instruments, may be heard to ‘converse’ with each other. Sometimes, though, the contrast between them suggests less a fruitful exchange than simple incompatibility. I then consider topic theory as a means of controlling our impressions of such diversity of musical materials, noting both its positive and its limiting aspects. To conclude, I consider the encompassing term ‘variety’, a desideratum of the time, which could, once more, be accounted a virtue or a vice.
We study Tate motives with integral coefficients through the lens of tensor triangular geometry. For some base fields, including $\overline{\mathbb{Q}}$ and $\overline{\mathbb{F}_{p}}$, we arrive at a complete description of the tensor triangular spectrum and a classification of the thick tensor ideals.
This note is about certain locally complete families of Calabi–Yau varieties constructed by Cynk and Hulek, and certain varieties constructed by Schreieder. We prove that the cycle class map on the Chow ring of powers of these varieties admits a section, and that these varieties admit a multiplicative self-dual Chow–Künneth decomposition. As a consequence of both results, we prove that the subring of the Chow ring generated by divisors, Chern classes, and intersections of two cycles of positive codimension injects into cohomology via the cycle class map. We also prove that the small diagonal of Schreieder surfaces admits a decomposition similar to that of K3 surfaces. As a by-product of our main result, we verify a conjecture of Voisin concerning zero-cycles on the self-product of Cynk–Hulek Calabi–Yau varieties, and in the odd-dimensional case we verify a conjecture of Voevodsky concerning smash-equivalence. Finally, in positive characteristic, we show that the supersingular Cynk–Hulek Calabi–Yau varieties provide examples of Calabi–Yau varieties with “degenerate” motive.
In Chapter 5, the Six Little Piano Pieces of Op. 19 are portrayed as a step in the direction of clear and traditional musical form, and more audible motivic processes, after the more abrupt forms and less obvious motivic relations (though far from non-existent) of Op. 11, No. 3, and Erwartung. I describe Pieces No. 2, 3, and 6 in detail, showing that these miniatures are organized by the same frameworks, “musical idea” and “basic image,” as previous works analysed in the book. Piece No. 2 manifests a musical idea that grows out of a conflict between hexatonic, octatonic, and whole-tone subsets, in which the hexatonic emerges victorious over the other two. Piece No. 3 expresses an “idea” of the same kind, but at the last minute the hexatonic collection’s ability to synthesize is thwarted by diatonic subsets. And piece No. 6, the famous portrayal of Mahler’s funeral bells, portrays an image of Schoenberg reaching up to take Mahler’s mantle as tonal composer, but falling back down into first pandiatonic territory and then chromaticism.
Chapter 2 demonstrates how the second and third Piano Pieces of Op. 11 form a cycle together with the first, in that they take up motives, harmonies, and processes that were introduced in the first piece, and use them to create narratives of conflict, elaboration, and solution – “musical ideas.” Op. 11’s processes include an expansion of pitch intervals within motives that generalizes into an expansion of pitch-class intervals within set classes, and an “explanatory” process that shows how unfamiliar pitch-interval collections can be reconciled to familiar motives through set-class identity with them. In Op. 11, No. 2, a conflict between set classes and motives similar to the one found in Op. 11, No. 1, is elaborated and resolved using the “explanatory” process, among other devices. In Op. 11, No. 3, the expanding and explanatory processes exist side by side in conflict, but rather than coming together in a solution, the expanding process simply crowds out the explanatory one, so that the “musical idea” is incomplete. My analysis of Op. 11, No. 3, pushes back against the common notion of the piece as “athematic,” in that it portrays the piece as a battle of motivic processes.
In this paper we study the subgroup of the Picard group of Voevodsky’s category of geometric motives $\operatorname{DM}_{\text{gm}}(k;\mathbb{Z}/2)$ generated by the reduced motives of affine quadrics. Our main tools here are the functors of Bachmann [On the invertibility of motives of affine quadrics, Doc. Math. 22 (2017), 363–395], but we also provide an alternative method. We show that the group in question can be described in terms of indecomposable direct summands in the motives of projective quadrics over $k$. In particular, we describe all the relations among the reduced motives of affine quadrics. We also extend the criterion of motivic equivalence of projective quadrics.
The introductory chapter begins by offering a rebuttal to Ethan Haimo’s claim in Schoenberg's Transformation of Musical Language (Cambridge, 2006) that “atonal” is an inappropriate term for Schoenberg's middle-period music. It does so by presenting Schenkerian analyses of “Jesus bettelt,” Op. 2, No. 2, and the first Piano Piece, Op. 11, demonstrating that the traditional contrapuntal structures of tonal music are present in the first piece, though often harmonized with unusual chords, but are incomplete or non-existent in the second piece. The chapter then proceeds to show how features originally characteristic of tonal music, other than typical Schenkerian middlegrounds, play crucial roles in organizing Op. 11, No. 1 – traditional tonal form, as well as motivic and harmonic processes that manifest and elaborate the “musical idea,” a conflict-elaboration-solution narrative.
Award-winning author Jack Boss returns with the 'prequel' to Schoenberg's Twelve-Tone Music (Cambridge, 2014) demonstrating that the term 'atonal' is meaningful in describing Schoenberg's music from 1908 to 1921. This book shows how Schoenberg's atonal music can be understood in terms of successions of pitch and rhythmic motives and pitch-class sets that flesh out the large frameworks of 'musical idea' and 'basic image'. It also explains how tonality, after losing its structural role in Schoenberg's music after 1908, begins to re-appear not long after as an occasional expressive device. Like its predecessor, Schoenberg's Atonal Music contains close readings of representative works, including the Op. 11 and Op. 19 Piano Pieces, the Op. 15 George-Lieder, the monodrama Erwartung, and Pierrot lunaire. These analyses are illustrated by richly detailed musical examples, revealing the underlying logic of some of Schoenberg's most difficult pieces of music.
Let $k$ be a number field. We describe the category of Laumon 1-isomotives over $k$ as the universal category in the sense of M. Nori associated with a quiver representation built out of smooth proper $k$-curves with two disjoint effective divisors and a notion of $H_{\text{dR}}^{1}$ for such “curves with modulus”. This result extends and relies on a theorem of J. Ayoub and L. Barbieri-Viale that describes Deligne's category of 1-isomotives in terms of Nori's Abelian category of motives.
In this work, we s uggest a defnition for the category of mixed motives generated by the motive h1 (E) for E an elliptic curve without complex multiplication. We then compute the cohomology of this category. Modulo a strengthening of the Beilinson-Soulé conjecture, we show that the cohomology of our category agrees with the expected motivic cohomology groups. Finally for each pure motive (Symnh1 (E)) (–1) we construct families of nontrivial motives whose highest associated weight graded piece is (Symnh1 (E)) (–1).
