Hypergraphs defined on algebraic structures
Get PDFThere has been a great deal of research on graphs defined on algebraic structures in the last two decades. Power graphs, commuting graphs, cyclic graphs are some examples. In this paper we begin an exploration of hypergraphs defined on algebraic structures, especially groups, to investigate whether this can add a new perspective.Peer reviewe
Pseudolaw, failure, and alternative temporality
Get PDFThis article considers the role of failure in the strategies of people practicing ‘pseudolaw,’ an alternative model of law and of legal history that never succeeds in actual courts. I argue that the guaranteed failure of these strategies may be less important than the creative possibilities they offer pseudolaw adherents for generating an alternative temporal order in which a sense of grievance and powerlessness over the past is rectified in the present.Peer reviewe
Evaluating the impact of individuals’ morningness-eveningness on the effectiveness of a habit-formation intervention for a simple and a complex behavior
Get PDFPlanning-based interventions are often used to help individuals form habits. Existing literature suggests a one-size-fits all approach to habit formation, but planning interventions may be optimized if tailored to individual differences and/or behavioral complexity. We test the hypothesis that planning to do a relatively complex behaviour (exercise) at a time that matches an individuals’ diurnal preference will facilitate behavioral engagement; whereas for a simpler behaviour (calcium supplementation), the optimal time-of-day for a new behavior will occur in the morning. Young, women volunteers (N=317) were randomly assigned to take calcium supplements or to exercise for 4 weeks and to control (no planning) or to one of three planning interventions (morning plan; evening plan; unassigned-time plan). Participants reported diurnal preference at baseline and habit strength and behavioral frequency weekly. Fitbit Zips and Medication Event Monitoring System Caps (MEMS) were used to objectively assess behavioral engagement. Multilevel modelling found that calcium supplementation was greatest for morning-types in the morning-cue condition, whereas exercise was greatest for morning types with morning cues and evening-types with evening cues. Habit-formation strategies may depend on diurnal preference and behavioral complexity. Future research can evaluate the role of other individual differences.Peer reviewe
Sovereign credit rating downgrades and Growth-at-Risk
Get PDFThis paper examines whether sovereign credit rating changes are linked to increased future macroeconomic downside risks based on the Growth-at-Risk framework by Adrian et al. (2019). Our findings reveal that downgrades significantly increase tail risk by lowering the 5th percentile of four-quarters ahead GDP growth by 2.95 percentage points, whereas upgrades yield a smaller and inconsistent effect of 0.45 percentage points. Standard panel OLS results show a reduced impact of 1.11 percentage points on GDP growth following a downgrade, underscoring the importance of examining effects beyond the mean. Further analysis reveals an asymmetrical impact across quantiles and time horizons, with speculative-grade countries particularly vulnerable to downgrades. Downgrades from all major agencies affect tail risk, with Fitch having the largest negative impact, while only Moody’s upgrades have a significant effect. Moreover, our empirical evidence suggests that the effect of credit rating downgrades is, at least partially mitigated, by the adoption of post-GFC regulatory reforms, aligning with these policies’ aim to reduce reliance on CRAs and enhance financial stability. Lastly, our analysis identifies investment and sovereign bond spreads as key channels through which downgrades affect macroeconomic outcomes, however, only the latter is significantly associated with downside risks to GDP growth. Robustness tests that include endogeneity checks, additional controls, alternative CRA data and quantile regression methodology, confirm our findings.Peer reviewe
Analytic theology, model pluralism, and progress
Get PDFIn recent discussions of methodology in analytic theology, attention has been paid to the use of model-building—providing simplified accounts of doctrines, or clusters of doctrines, that merely approximate to the truth of the matter—as a practice that enables analytic theologians to carry out their work whilst respecting the mystery, ineffability, and unintelligibility of God. However, this raises a question concerning the nature of progress in this endeavour. If we cannot produce a model that fully captures the truth of the matter, how do we conceptualise progress in our understanding of these doctrines? Building on the work of Walter Veit in philosophy of science, I will propose a model pluralist account that suggests that progress in our understanding of theological doctrines consists of the development and assessment of multiple models, and not in our development of one perfectly accurate model.Peer reviewe

These new planets orbit relatively bright (G ≤ 12.5) FGK host stars with orbital periods between 1.6 and 8.2 days, and have radii between 0.9 and 1.7 Jupiter radii. We performed follow-up ground-based photometry, high angular resolution imaging, high-resolution spectroscopy, and radial velocity monitoring for each of these objects to confirm that they are planets and determine their masses and other system parameters. The planets’ masses span more than an order of magnitude (0.17 MJ < Mp < 3.3 MJ). For two planets, TOI-3593 b and TOI-4961 b, we measured significant nonzero eccentricities of 0.11-0.03+0.05 and 0.18-0.05+0.04 , respectively, while for the other planets, the data typically provide a 1σ upper bound of 0.15 on the eccentricity. These discoveries represent a major step toward assembling a complete, magnitude-limited sample of transiting hot Jupiters around FGK stars.Peer reviewe
If I Deign to Say Something : using intentionality and catholicity to explore a composer’s practice
Get PDFComposition is arguably the musical practice most obscured from external observation for interpretation. The distance between a composer and listeners of their music, between a composer’s intentions and the outcomes of their music, is an inevitable gap for third parties to cross when analysing a score. Scholarly inquiry into a composer and his or her individual works is primarily carried out by those who aren’t the composer, leading to minimal first-hand contributions of new musical insights from the composer’s account and the very creative thoughts which produced the score. Is it possible to learn more from the conscious creative forces at work in a composition practice? Can a first-person, emic perspective on composition take into account its context within modern society and offer new methods for regarding music on a path towards a more peaceful and harmonious coexistence? This portfolio and commentary explore these questions by establishing phenomenological and theological methods scaffolded by semiotic and hermeneutic theoretical frameworks. These methods observe and document the interior insights gleaned from the level of the composer’s mind in this practice-as-research
Health care itineraries for women in situations of abortionmethodological aspects of a qualitative study for Birth in Brazil II survey
Get PDFIn recent decades, several academic studies on abortion have been produced in Brazil, with different designs, objectives, and methodologies. However, due to the diversity of situations in which Brazilian women experience abortion, the complexity of this topic, and its modulations in different political and sociocultural contexts, it still challenges academicians and the fields of health and reproductive rights. In this article, we present methodological aspects of a qualitative study on health care itineraries of women in situations of abortion, a component of the Birth in Brazil II survey, whose objective is to discuss the effects of gender; race/ethnicity; social class; generational, regional, and territorial inequalities on care itineraries. We discuss the study design development, the construction of the theoretical framework and specific analytical axes, the development of interview instrument, definition of participant selection criteria, strategies to contact participants and conduct the interviews, management of field work and materials produced, analytical procedures, and ethical issues. In total, 120 narrative interviews were conducted in order to include a diversity of women and obtain detailed results from the quantitative analysis under Birth in Brazil II survey. The context of criminalization of abortion has an impact on the production of knowledge on this subject, creating challenges such as difficult access to women, women's anonymity, privacy and data confidentiality, creation of objective and subjective conditions so that they can narrate their experiences in depth. With this article, we seek to contribute to the debate about these challenges in abortion research in Brazil.Peer reviewe
Vocal sequence diversity and length remain stable across ontogeny in a catarrhine monkey (Cercocebus atys)
Get PDFFunding: This study was funded by the Max Planck Society (M.IF.EVAN 8103 – to C.C. and R.M.W. through the Evolution of Brain Connectivity Project). Open access funding provided by the Max Planck Society. This study was funded by the Max Planck Society within the Hominoid Brain Connectomics Project through the Max Planck Society (M.IF.NEPF8103 and M.IF.EVAN8103).During childhood, human speech utterances increase steadily in complexity, length and diversity. In contrast, the vocal repertoire of non-human primates has long been considered fixed from birth. Recent studies showing the acquisition of vocal sequences during ontogeny in chimpanzees and marmosets challenge this view. Here we further explore the potential flexibility of non-human primate vocal production by comparing the vocal sequence repertoire across age groups in sooty mangabeys, a species with a rich sequence repertoire for a catarrhine monkey. We recorded 1844 utterances from 75 individuals from two wild groups in Taï National Park, Ivory Coast. We used custom-made Bayesian models specifically designed to estimate the individual repertoire size of vocal sequences while accounting for under-sampling of certain vocalisations in certain individuals. We hereby provide a tool to estimate vocal repertoire size applicable to other taxa. We found no relevant ontogenetic changes in vocal repertoire size and utterance length. Ontogenetic vocal sequence expansion is therefore not universal among primates that routinely use vocal sequences to communicate. Rather, this feature may have evolved independently in distantly-related taxa due to social features thought to promote vocal complexity, such as the complex social organisation of chimpanzees and the cooperative breeding systems of marmosets.Peer reviewe
The generation of houses and children in Bahiapaternity and relatedness in the lower south
No full textIn “Riachão”, a village of fishermen and seafood harvesters in Bahia state’s “lower South” region, recognition of paternity occurs in the period between conception and the process of making a pregnancy public. People situate themselves as relatives and affines through houses, which are key agents in the constitution of relatedness. The ethnographic discussion makes clear how relatedness emerges in the dynamics of lovemaking, sexual initiation, procreation, and the fabrication of paternity, in which houses are always present. To create kinship in this context, it is necessary to propagate houses. The article contributes to the study of kinship and the social aspects of reproduction in Brazil through problematizing treatment of biological organisms and physiological processes as separate from the material worlds they inhabit and from the objects and things through which they are constituted. Simultaneously, the discussion of the forging of paternal connections in “Riachão” contributes to the literature on “house-ing” through a focus on the imbrication between processes of making new persons, new houses, and relatedness.Peer reviewe
