Adelante!Military Imaginaries, the Cold War, and Southern Africa's Liberation Armies
Authors: Alexander Jocelyn , McGregor Joann 
Published: June 2020

AbstractStudies of southern Africa's liberation movements have turned attention to the great importance of their transnational lives, but have rarely focused on the effects of the military training Cold War-era allies provided in sites across the globe. This is a significant omission in the history of these movements: training turns civilians into soldiers and creates armies with not only military but also social and political effects, as scholarship on conventional militaries has long emphasized. Liberation movement armies were however different in that they were not subordinated to a single state, instead receiving training under the flexible rubric of international solidarity in a host of foreign sites and in interaction with a great variety of military traditions. The training provided in this context produced multiple “military imaginaries” within liberation movement armies, at once creating deep tensions and enabling innovation. The article is based on oral histories of Zimbabwe People's Revolutionary Army (ZIPRA) veterans trained by Cuban and Soviet instructors in Angola in the late 1970s. These soldiers emerged from the Angolan camps with a military imaginary they summed up in the Cuban exhortation “Adelante!” (Forward!). Forty years later, they stressed how different their training had made them from other ZIPRA cadres, in terms of their military strategy, mastery of advanced Soviet weaponry, and aggressive disposition, as well as their “revolutionary” performance of politics and masculinity in modes of address, salute, and drill. Such military imaginaries powerfully shaped the southern African battlefield. They offer novel insight into the distinctive institutions, identities, and memories forged through Cold War-era military exchanges.
Staging Rachel: Rabbinic Midrash, Theatrical Mime, and Christian Martyrdom in Late Antiquity
Authors: Hadjittofi Fotini , Sivan Hagith 
Published: June 2020

AbstractLamentations Rabbah Proem 24, a late ancient rabbinic midrash, is in many ways a unique text within the entire rabbinic corpus. It presents an extraordinary array of characters (including Abraham, Moses, the Torah, and even the alphabet) who are called upon to placate God, but fail. As their quest proves inconclusive, the biblical Rachel jumps into the fray to tell her story: how out of sisterly compassion she allowed Leah to take her own place in the conjugal bed on “her” wedding night. Disclosing to her sister the secretive “signs” she had shared with Jacob, Rachel crawled under the nuptial bed to respond to Jacob whenever he spoke. This scandalous autobiography transforms an apparent instance of illicit sex, the ideal material for theatrical stage mimes, into an act of martyrdom and sublime compassion. This article argues that the performance culture of the late ancient Mediterranean world provides the key for assessing this text’s originality. We begin with an analysis of the text, drawing attention to its theatrical qualities and its relationships with contemporary visual imagery (mosaics) and texts from outside the rabbinic milieu (Christian Apocrypha). We then examine the casting of midrashic Rachel as a response to both the mimic adulteress and the Christian martyr. Finally, we consider rabbinic familiarity with mime, particularly with its usefulness as a social mediator and agent of collective catharsis. It is precisely these aspects of mimic performance, we argue, that Rachel’s vignette appropriates in this fascinating rabbinic text.
El Salvador vs. Imperialismo Yanqui, 1912–14
Authors: Lindo-Fuentes Héctor 
Published: June 2020

AbstractWhen the United States invaded Nicaragua in 1912 the popular reaction in El Salvador was so strong that it completely upended politics. The article argues that this anti-imperialist movement, completely ignored by the current historiography, forced Salvadorean governments to make decisions regarding foreign policy that would have been unthinkable had it not been for the pressure from below. Popular pressures contributed to limit the scope of the final version of the Chamorro–Bryan Treaty between the United States and Nicaragua. The treaty did not include Platt Amendment-like provisions. Moreover, the Wilson administration abandoned the idea of extending a protectorate to all the Central American countries and building a naval base in the Gulf of Fonseca.
When expanding training from working memory to emotional working memory: not only improving explicit emotion regulation but also implicit negative control for anxious individuals

Published: June 2020

AbstractBackgroundThe effect of working memory training (WM-T) has been found to transfer to emotional wellbeing, despite some debate on whether an affective component in training is necessary to achieve specific emotion-related benefits. These novel cognitive trainings have not yet been tested in highly anxious individuals, who have deficits in implicit and explicit emotional regulation and should be the potential beneficiaries of these trainings.MethodsWe designed two types of mobile phone-based training applications: (1) WMT and (2) an emotional working memory training (EWM-T) that comprised negative face distraction. Ninety-eight participants (33, WM-T; 35, EWM-T; 30, Control group) with high trait anxiety completed the 21-day intervention or placebo program and conducted pre- and post-test procedures, including questionnaires, emotional regulation and emotional Stroop tasks alongside electroencephalogram recording. Late positive potential (LPP) in emotion regulation task and P3 in the emotional Stroop task were adopted as neutral indicators for the explicit and implicit affective regulation/control processing.ResultsThose who had received training (WM-T and EWM-T) showed enhanced explicit regulation (indexed by reduced LPP during reappraisal) compared with the control. Besides, individuals in EWM-T showed reduced behavioral attention bias and a decline of P3 in response to negative faces in an emotional Stroop task. The altered neural indicators were correlated with corresponding behavior indexes that contributed to the anxiety alleviation.ConclusionsThe general WM-T was effective in enhancing explicit emotional regulation, while training with emotional add-in further improved implicit emotional control. (E)WM-T shows potential as a beneficial intervention for the anxiety population.

Published: June 2020

SUMMARYFor acquiring a broad view in an unknown environment, we proposed a control strategy based on the Bézier curve for the snake robot raising its head. Then, an improved discretization method was developed to accommodate the backbone curves with more complex shapes. Besides, in order to determine the condition of using the improved discretization method, energy of framed space curve is introduced originally to estimate the shape complexity of the backbone curve. At last, based on degree elevation of the Bézier curve, an obstacle avoidance strategy of the head-raising motion was proposed and validated through simulation.
Evaluating the fitness effects of seed size and maternal tree size onPolylepis tomentella(Rosaceae) seed germination and seedling performance
Authors: Domic Alejandra I. , Capriles José M. , Camilo Gerardo R. 
Published: June 2020

AbstractIn vascular plants, larger seeds are generally associated with higher germination potential, healthier seedlings and overall higher rates of survivorship. How this relationship holds or what other physiological tradeoffs evolved in plants adapted to high-altitude environments, such as the tropical and subtropical highlandPolylepistree, remain unclear. In this study, we evaluated the relationship between seed mass and seedling performance by testing the reserve effect, the metabolic effect, and the seedling-size effect hypotheses inPolylepis tomentellaWeddell (Rosaceae). Since the relationship between fitness and seed size can often depend on maternal plant size, we additionally investigated the association between germination success, seedling performance (survival, relative growth rate (RGR) and height), and size of bearing-seed trees under controlled greenhouse conditions. Our results showed that heavier seeds are more likely to germinate, but we did not find evidence that could support the reserve effect, metabolic effect or seedling-size effect. As seedlings from larger and medium seeds exhibited comparatively similar RGR, survival percentages and final size, maternal plant size was positively associated with improved seed quality and seedling performance. These results demonstrate that seed mass and maternal size during early seedling establishment are critical forPolylepispersistence, demography and conservation.
Reflect, Revisit, Reimagine: Language Assessment inARAL
Authors: Chapelle Carol A. 
Published: June 2020

AbstractThis 40thanniversary ofARALalso marks the 40-year anniversary of a significant uptick in research on language assessment, and hence there is much to reflect on and revisit within this period—and still scope for imagining the future. Pre-1980, language assessment had a long history, but Spolsky (1995) designated the late 1940s as a time of professionalization, which continued through the following decades. By the 1970s, language testers were gradually organizing into an academic community with an annual international conference, regional conferences, journals, and scholarly books. The new academic community not only developed and used language tests but also investigated the validity of their interpretations and uses. Canale's (1987) paper inARALprovides an enduring frame of reference for reflection on the concerns of the academic community, which he introduced as thewhat,how, andwhyof language assessment.
Sampling Bias and the Problem of Generalizability in Applied Linguistics
Authors: Andringa Sible , Godfroid Aline 
Published: June 2020

AbstractIn this final contribution to the issue, we discuss the important concept of generalizability and how it relates to applied linguists’ ability to serve language learners of all shades and grades. We provide insight into how biased sampling in Applied Linguistics currently is and how such bias may skew the knowledge that we, applied linguists, are building about second language learning and instruction. For example, our conclusions are often framed as universally-applying, even though the samples that have given rise to them are highly specific and Western, Educated, Industrialized, Rich, and Democratic (WEIRD; Henrich, Heine, & Norenzayan, 2010). We end with a call for research and replication in more diverse contexts and with more diverse samples to promote progress in the field of Applied Linguistics as ARAL celebrates its 40th anniversary.
African Americans in World Language Study: The Forged Path and Future Directions
Authors: Anya Uju 
Published: June 2020

AbstractThis article examines the history of African Americans in the academic study of world languages and presents an overview of inquiry on the topic. The paper focuses on the impact of race in second language acquisition (SLA) as exemplified through the experience of black students in language education and study abroad. It discusses objectives, policies, instructional priorities and strategies, conditions, and materials related to how black students have in the past, are currently, or should be engaged in language learning. The article examines the path forged by African Americans in world language study, signals gaps in the present body of knowledge, and suggests future directions for investigations into this important topic in the field of applied linguistics and SLA forARAL's 40th anniversary.
Indigenous Language Revitalization and Applied Linguistics: Parallel Histories, Shared Futures?
Authors: McIvor Onowa 
Published: June 2020

AbstractDamages done to Indigenous languages occurred due to colonial forces, some of which continue to this day, and many believe efforts to revive them should involve more than Indigenous peoples alone. Therefore, the need for learning Indigenous languages as “additional” languages is a relatively new societal phenomenon and Indigenous language revitalization (ILR) an emerging academic field of study. As the ILR body of literature has developed, it has become clear that this work does not fit neatly into any single academic discipline. While there have been substantial contributions from linguistics and education, the study and recovery of Indigenous languages are necessarily self-determined and self-governing. Also, due to the unique set of circumstances, contexts, and, therefore, solutions needed, it is argued that this discipline is separate from, yet connected to, others. Applied linguists hold specific knowledge and skills that could be extended to ILR toward great gains. This paper explores current foci within ILR, especially concepts, theories, and areas of study that connect applied linguistics and Indigenous language learning. The intention of this paper is to consider commonalities, differences, current and future interests for shared consideration of the potential of collaborations, and partnerships between applied linguistics and ILR scholars.
Is an Antiracist and Decolonizing Applied Linguistics Possible?
Authors: Motha Suhanthie 
Published: June 2020

AbstractThis article argues for an uncovering of the multitude of ways in which applied linguistics has functioned as an important and effective vehicle for White supremacy and empire, with its disciplinary roots embedded in assumptions about racial inequalities and racial hierarchies and, equally importantly, the concealment of these forms of racial discrimination which often manifest as innocuous language practices. In particular, the notion of objectivity has played a guiding role in reinscribing Whiteness in much applied linguistics theorizing and research within a global context of inequitable racial power and forms of knowledge production and transmission that are steeped in colonial reasoning. In this piece, the author considers what antiracism and decolonization mean within applied linguistics and asks: Is the discipline of applied linguistics irretrievably rooted in an ontology of race and empire? Or is an antiracist and decolonizing applied linguistics possible?
A systematic review of gene-by-intervention studies of alcohol and other substance use
Authors: Neale Zoe E. , Kuo Sally I-Chun , Dick Danielle M. 
Published: June 2020

AbstractAlcohol and other substance use problems are common, and the efficacy of current prevention and intervention programs is limited. Genetics may contribute to differential effectiveness of psychosocial prevention and intervention programs. This paper reviews gene-by-intervention (G×I) studies of alcohol and other substance use, and implications for integrating genetics into prevention science. Systematic review yielded 17 studies for inclusion. Most studies focused on youth substance prevention, alcohol was the most common outcome, and measures of genotype were heterogeneous. All studies reported at least one significant G×I interaction. We discuss these findings in the context of the history and current state of genetics, and provide recommendations for future G×I research. These include the integration of genome-wide polygenic scores into prevention studies, broad outcome measurement, recruitment of underrepresented populations, testing mediators of G×I effects, and addressing ethical implications. Integrating genetic research into prevention science, and training researchers to work fluidly across these fields, will enhance our ability to determine the best intervention for each individual across development. With growing public interest in obtaining personalized genetic information, we anticipate that the integration of genetics and prevention science will become increasingly important as we move into the era of precision medicine.
On finite sets of small tripling or small alternation in arbitrary groups
Authors: Conant Gabriel 
Published: June 2020

AbstractWe prove Bogolyubov–Ruzsa-type results for finite subsets of groups with small tripling, |A3| ≤ O(|A|), or small alternation, |AA−1A| ≤ O(|A|). As applications, we obtain a qualitative analogue of Bogolyubov’s lemma for dense sets in arbitrary finite groups, as well as a quantitative arithmetic regularity lemma for sets of bounded VC-dimension in finite groups of bounded exponent. The latter result generalizes the abelian case, due to Alon, Fox and Zhao, and gives a quantitative version of previous work of the author, Pillay and Terry.
Sampling biased monotonic surfaces using exponential metrics
Authors: Greenberg Sam , Randall Dana , Streib Amanda Pascoe 
Published: June 2020

AbstractMonotonic surfaces spanning finite regions of ℤd arise in many contexts, including DNA-based self-assembly, card-shuffling and lozenge tilings. One method that has been used to uniformly generate these surfaces is a Markov chain that iteratively adds or removes a single cube below the surface during a step. We consider a biased version of the chain, where we are more likely to add a cube than to remove it, thereby favouring surfaces that are ‘higher’ or have more cubes below it. We prove that the chain is rapidly mixing for any uniform bias in ℤ2 and for bias λ > d in ℤd when d > 2. In ℤ2 we match the optimal mixing time achieved by Benjamini, Berger, Hoffman and Mossel in the context of biased card shuffling [2], but using much simpler arguments. The proofs use a geometric distance function and a variant of path coupling in order to handle distances that can be exponentially large. We also provide the first results in the case of fluctuating bias, where the bias can vary depending on the location of the tile. We show that the chain continues to be rapidly mixing if the biases are close to uniform, but that the chain can converge exponentially slowly in the general setting.
Ramsey properties of randomly perturbed graphs: cliques and cycles
Authors: Das Shagnik , Treglown Andrew 
Published: June 2020

AbstractGiven graphs H1, H2, a graph G is (H1, H2) -Ramsey if, for every colouring of the edges of G with red and blue, there is a red copy of H1 or a blue copy of H2. In this paper we investigate Ramsey questions in the setting of randomly perturbed graphs. This is a random graph model introduced by Bohman, Frieze and Martin [8] in which one starts with a dense graph and then adds a given number of random edges to it. The study of Ramsey properties of randomly perturbed graphs was initiated by Krivelevich, Sudakov and Tetali [30] in 2006; they determined how many random edges must be added to a dense graph to ensure the resulting graph is with high probability (K3, Kt) -Ramsey (for t ≽ 3). They also raised the question of generalizing this result to pairs of graphs other than (K3, Kt). We make significant progress on this question, giving a precise solution in the case when H1 = Ks and H2 = Kt where s, t ≽ 5. Although we again show that one requires polynomially fewer edges than in the purely random graph, our result shows that the problem in this case is quite different to the (K3, Kt) -Ramsey question. Moreover, we give bounds for the corresponding (K4, Kt) -Ramsey question; together with a construction of Powierski [37] this resolves the (K4, K4) -Ramsey problem.We also give a precise solution to the analogous question in the case when both H1 = Cs and H2 = Ct are cycles. Additionally we consider the corresponding multicolour problem. Our final result gives another generalization of the Krivelevich, Sudakov and Tetali [30] result. Specifically, we determine how many random edges must be added to a dense graph to ensure the resulting graph is with high probability (Cs, Kt) -Ramsey (for odd s ≽ 5 and t ≽ 4).To prove our results we combine a mixture of approaches, employing the container method, the regularity method as well as dependent random choice, and apply robust extensions of recent asymmetric random Ramsey results.
Cocaine use in university students: relationships with demographics, mental health, risky sexual practices, and trait impulsivity
Authors: Chamberlain Samuel R. , Lust Katherine , Grant Jon E. 
Published: June 2020

AbstractBackgroundCocaine is increasingly used on a recreational basis by the general population with potential implications for mental health. The aim of this study was to assess how common cocaine use is, and its mental health associations, in a large sample of university students.MethodsApproximately 10 000 university students were invited to take part in an online survey, which assessed the use of cocaine (ever or past year), alcohol and drug use, mental health issues, and impulsive and compulsive tendencies. Group differences in demographic and clinical characteristics were characterized.ResultsA total of 3520 university students (57.7% female) completed the survey. Of these, 110 students (3.1%) reported using cocaine in the preceding year, and a further 163 students (4.6%) reported historical use more than a year ago. Cocaine use was associated with more years as a student, lower grade point averages, more use of other drugs, riskier sexual practices, post-traumatic stress disorder, attention deficit hyperactivity disorder, treatment for psychological/emotional problems (including taking prescribed medication), and trait impulsivity. Of these associations, the link with trait impulsivity had the largest effect size.ConclusionHistory of cocaine use appears relatively common in university students; and has a number of untoward associations in terms of mental health, use of other substances, and risky sexual practices. The most marked finding (in terms of effect size) was the link between cocaine use and trait impulsivity, supporting the importance of this construct in seeking out candidate vulnerability markers for use of cocaine and other drugs. Future work should use longitudinal designs to further characterize the nature of these associations.

AbstractThe objective of this study was to identify attitudes towards the scientific search for extraterrestrial life among students from public and private universities in Peru. This research was inspired by similar studies, realized in Sweden, which used the same instrument adapting it to our reality. The process consisted of a survey of the Peruvian student population by targeting it in different regions of Peru. The sample consisted of 1237 students from different academic areas. The findings show that 92% of the students believe in the existence of life outside our planet, with differences between the subgroups surveyed.
