This study investigates associations of several dimensions of childhood adversities (CAs) with lifetime mental disorders, 12-month disorder persistence, and impairment among incoming college students.
Data come from the World Mental Health International College Student Initiative (WMH-ICS). Web-based surveys conducted in nine countries (n = 20 427) assessed lifetime and 12-month mental disorders, 12-month role impairment, and seven types of CAs occurring before the age of 18: parental psychopathology, emotional, physical, and sexual abuse, neglect, bullying victimization, and dating violence. Poisson regressions estimated associations using three dimensions of CA exposure: type, number, and frequency.
Overall, 75.8% of students reported exposure to at least one CA. In multivariate regression models, lifetime onset and 12-month mood, anxiety, and substance use disorders were all associated with either the type, number, or frequency of CAs. In contrast, none of these associations was significant when predicting disorder persistence. Of the three CA dimensions examined, only frequency was associated with severe role impairment among students with 12-month disorders. Population-attributable risk simulations suggest that 18.7–57.5% of 12-month disorders and 16.3% of severe role impairment among those with disorders were associated with these CAs.
CAs are associated with an elevated risk of onset and impairment among 12-month cases of diverse mental disorders but are not involved in disorder persistence. Future research on the associations of CAs with psychopathology should include fine-grained assessments of CA exposure and attempt to trace out modifiable intervention targets linked to mechanisms of associations with lifetime psychopathology and burden of 12-month mental disorders.
A recently developed mixing length model of the turbulent shear stress in pipe flow is used to solve the streamwise momentum equation for fully developed channel flow. The solution for the velocity profile takes the form of an integral that is uniformly valid from the wall to the channel centreline at all Reynolds numbers from zero to infinity. The universal velocity profile accurately approximates channel flow direct numerical simulation (DNS) data taken from several sources. The universal velocity profile also provides a remarkably accurate fit to simulated and experimental flat plate turbulent boundary layer data including zero and adverse pressure gradient data. The mixing length model has five free parameters that are selected through an optimization process to provide an accurate fit to data in the range $R_\tau = 550$ to $R_\tau = 17\,207$. Because the velocity profile is directly related to the Reynolds shear stress, certain statistical properties of the flow can be studied such as turbulent kinetic energy production. The examples presented here include numerically simulated channel flow data from $R_\tau = 550$ to $R_\tau =8016$, zero pressure gradient (ZPG) boundary layer simulations from $R_\tau =1343$ to $R_\tau = 2571$, zero pressure gradient turbulent boundary layer experimental data between $R_\tau = 2109$ and $R_\tau = 17\,207$, and adverse pressure gradient boundary layer data in the range $R_\tau = 912$ to $R_\tau = 3587$. An important finding is that the model parameters that characterize the near-wall flow do not depend on the pressure gradient. It is suggested that the new velocity profile provides a useful replacement for the classical wall-wake formulation.
When dealing with instructional information, working memory can be divided into auditory and visual processors. The capacity limits of each processor are a major impediment when students are required to learn new material. Nevertheless, there is one strategy that can effectively expand working memory capacity by using the partially independent status of the auditory and visual processors. Under specific and well-defined conditions, presenting some information in visual mode and other information in auditory mode can increase effective working memory capacity and so reduce the effects of cognitive overload. This effect is called the instructional modality effect or modality principle. It is an instructional principle that can substantially increase learning. This chapter discusses the theory and data that underpin the principle and the instructional implications that flow from the principle.
The burden of depression is increasing worldwide, specifically in older adults. Unhealthy dietary patterns may partly explain this phenomenon. In the Spanish PREDIMED-Plus study, we explored (1) the cross-sectional association between the adherence to the Prime Diet Quality Score (PDQS), an a priori-defined high-quality food pattern, and the prevalence of depressive symptoms at baseline (cross-sectional analysis) and (2) the prospective association of baseline PDQS with changes in depressive symptomatology after 2 years of follow-up. After exclusions, we assessed 6612 participants in the cross-sectional analysis and 5523 participants in the prospective analysis. An energy-adjusted high-quality dietary score (PDQS) was assessed using a validated FFQ. The cross-sectional association between PDQS and the prevalence of depression or presence of depressive symptoms and the prospective changes in depressive symptoms were evaluated through multivariable regression models (logistic and linear models and mixed linear-effects models). PDQS was inversely associated with depressive status in the cross-sectional analysis. Participants in the highest quintile of PDQS (Q5) showed a significantly reduced odds of depression prevalence as compared to participants in the lowest quartile of PDQS (Q1) (OR (95 %) CI = 0·82 (0·68, 0·98))). The baseline prevalence of depression decreased across PDQS quintiles (Pfor trend = 0·015). A statistically significant association between PDQS and changes in depressive symptoms after 2-years follow-up was found (β (95 %) CI = −0·67 z-score (–1·17, −0·18). A higher PDQS was cross-sectionally related to a lower depressive status. Nevertheless, the null finding in our prospective analysis raises the possibility of reverse causality. Further prospective investigation is required to ascertain the association between PDQS and changes in depressive symptoms along time.
This chapter examines the cultural status of ritual song and dance in the Roman Late Republican and Augustan periods. By applying the modern theoretical work of Paul Connerton on the social reproduction of memory, the chapter explores several strategies through which two of the most iconic religious associations in Rome – the Salian priesthood and the Arval Brethren – stored and transmitted their cultural traditions. The hymns of these collegia, as well as their performances, constitute unique artifacts for understanding the interconnected processes of writing and embodiment – what Connerton defines as “inscription” and “incorporation”– in the production of ancient musical memories.
In 1883, abolitionists, led by José do Patrocínio, followed the North-American example, and launched a campaign for creating free soils. The strategy consisted of buying up freedom certificates or persuading slave owners to give them for free at intervals. The tactic did not work well in the capital of the Empire. Then Patrocínio joined the campaign in Ceará, selected for having small slave stocks, strong local abolitionist associations, and a provincial president willing to support the movement. Abolitionists went house to house, city by city, and started a countdown to province-wide abolition. Patrocínio traveled to Paris, where, as Nabuco in London, organized events to showcase the movement’s international support and embarrass the national government, thus preventing repression. In March 1884, abolitionists declared Ceará to be "free soil." On the eve of mobilization, Patrocínio and Rebouças created the Abolitionist Confederation, embracing all abolitionist associations all over the country, and launched a manifesto for the immediate and non-indemnified abolition of slavery. The Abolitionist Confederation continued the free soil campaign around the country and organized propaganda events in the public space, making abolitionist presence impossible to be ignored. This strategy caused a crisis in the political institutions and a growing pro-slavery reaction.
In the 1870s the growth of urbanization, the expanded access to tertiary education, and the reduced printing costs broadened the range of participants in the public debate in Brazil. Abolitionists addressed this public with the rhetoric of change. The Brazilian moral repertoire emulated former abolitionist movements rationale, presenting abolition as an act of compassion, a right, and a sign of progress. However, differently from the Anglo-American case, Brazilians scarcely relied on religious arguments, instead employing scientific and artistic language for increasing the awareness of its urban audience. This rhetoric was used by all abolitionists, with distinctive emphasis. The black abolitionist Luís Gama was responsible for the diffusion of a style of activism heavily based on the rhetoric of rights. Gama started freedom lawsuits, later emulated all over the country. In contrast with Abílio Borges and Andre Rebouças, Gama was an elite outsider and attracted non-elite members to abolitionist activism. At this point, Rebouças recognized a similarity to him: traveling to the US, he was not regarded as an aristocrat, unlike in Europe, but as a black man. He then took Frederick Douglass as a model to fight slavery.
The nationalization of abolitionism came about when slavery returned to the institutional agenda in 1878, thanks to the full implementation of the free-womb law and the change of government. After a decade of demanding reforms in the public space, the Liberals were in power. The abolitionists seized the opportunity to step up their protest. A new generation, in part benefiting from the educational reforms of the 1870s, joined the mobilization. Among them was the black journalist José do Patrocínio, who joined Rebouças in founding an abolitionist association and started the “concert-conferences”, an expansion of Abílio Borges´s civic conferences. Held in theaters, with poetry rrecitations and operas, these events ended with the presentation of manumission certificates and a shower of flowers over the freed slaves.This was the preferred abolitionist strategy in the following years, a pacific style of mobilization, which conferred public legitimacy upon the campaign in the large cities and allowed women to enter the campaign. Numeric growth, geographic expansion, tactical variety, and the social diversity of the activists allowed the movement to become national.
The crisis led, in June 1884, to the appointment of a new Prime Minister, the Liberal Manuel de Souza Dantas, committed to a moderate abolitionist reform. The Abolitionist Confederation coordinated abolitionists nationwide to endorse the government and helped draft a proposal for gradual emancipation and conceiving rights to freed people, presented to Parliament in July 1884.The alliance government movement triggered a pro-slavery political backlash, with the creation of civil associations (Plantation Clubs) against the Dantas reform, while the caucus worked to obstruct it in parliament. Dantas then dissolved the House and called new elections. Joaquim Nabuco returned to Brazil to be the star of the coalition abolitionist movement/government, that stood candidates for parliament, in a nationwide abolitionist electoral campaign. The freedom soil campaign continued at the same time. The pro-slavery political faction managed to control the results of the election.The Dantas government fell and the gradual emancipation project was thwarted.
This book, based on a dataset with 2,214 abolitionist events, makes the case that the campaign for the abolition of slavery in Brazil was a structured and lasting network of activists, associations, and public demonstrations, a national social movement. In this sense, this study shows civil society mobilization was not a particular feature of Anglo-American abolitionism.The Brazilian abolitionist movement's actions are explained here from a relational perspective, focusing on its contentious relations – in the public space and inside political institutions – with governments as well as with a pro-slavery countermovement. Besides, the book places Brazil in a global history of abolitionist movements, showing how local activists hooked onto the global abolitionist network and appropriated the repertoire of contention – rhetoric, strategies, and political performances – put together by previous anti-slavery movements. Brazilians adapted this repertoire to local political tradition. Given the formal link between church and State in Brazil, abolitionists preferred secular rhetoric and theater to propaganda. In this sense, it was more modern than the somewhat religiously embedded Anglo-Saxon abolitionism.
This book argued that the Brazilian antislavery mobilization proved to be a national social movement. The movement chose strategies according to a shifting balance of power, giving to the government´s tolerance or repression, the availability of allies, and the pro-slavery countermovement´s strength. This relational dynamic movement/state/countermovement forced abolitionists to favor successful demonstrations in the public space, field candidates for political institutions, and civil disobedience.Three mechanisms explain the geographical expansion and continuity of Brazilian abolitionism through two decades: the building up of national activism networks, portable activism styles (easily reproducible political performances) and political brokers (the key broker was André Rebouças). Brazilian abolitionists relied on a repertoire of former antislavery movements and adapted it to local political traditions. Givem the formal link between church and State in Brazil, abolitionists used secular rhetoric and theater as propaganda. In this sense, it was more modern than the somewhat religiously embedded Anglo-Saxon abolitionism. This study shows civil society mobilization was not a particular feature of Anglo-American abolitionism. Besides, it demonstrated the placement of national actors in a global network of activism, making a case for including Brazil in the transnational history of abolitionism.
In 1885, the Conservative Party/pro-slavery countermovement took power and closed the institutional agenda to abolition. Besides, the government started to repress abolitionist acts in the public space. The new Prime Minister, the Baron of Cotegipe, rolled out a repressive program, using legal measures, and allowed the pro-slavery countermovement to relying on extra-legal methods. The harassing, persecuting, and arresting of abolitionists increased. The movement then shifted from public demonstrations to civil disobedience, and clandestine activities. Based on the North-American underground railway strategy, abolitionists set up assisted collective runaway routes to get slaves to “free soil”. Abolitionists also declared in their newspapers their willingness to take up arms to defend their activists and liberate slaves. This radicalization made it impracticable to maintain slavery without the use of force. This was a phase of confrontation since the government counted on military repression and the pro-slavery countermovement´s militias to face the abolitionists' strategy.
