Basque Nationalism and Education: The influence of Euskara on student achievement in the Basque Country

Between 2012 and 2015, Programme for International Student Assessment (PISA) test scores in the Basque Country have dropped significantly. In reading, the average score dropped 7 points and in math, scores fell by 13 points. Most notably however, science proficiency plummeted 23 points between 2012 and 2015. With 2018 PISA data yet to be published, this downturn in the educational success of the Basque Country is drawing significant concern from educators, parents, and policymakers alike. These concerns are bolstered by the fact that Basque public schools spend €3,712 more per pupil than average expenditure of Spain, yet perform slightly lower than the state and multiple other autonomous regions in all three subjects. This has led many to ask why, if education spending is significantly higher, the region is economically prosperous, and there is little diversity among the population, are Basque schools performing below the Spanish average? Likewise, what is fueling the overall downward trend in Basque scores? These questions reignite the ongoing debate about the efficacy of using Euskara, the Basque language as a medium of instruction. In many respects, the emergence of Basque as a language of instruction is considered to be politically motivated rather than the result of positive pedagogical outcomes. Therefore, in this paper, I hope to examine how Basque nationalism, operationalized by Euskara as a language of instruction, impacts student outcomes and educational achievement in the Basque Country. By examining the Basque Country’s performance on the 2015 PISA exam among a number of important education factors: school type, language of instruction, language of the exam, and socioeconomic status, I aimed to determine what may have caused the overall decrease in scores in the Basque Country. The results of my research shows that above all other factors, socioeconomic status and the overall downturn in the Economic, Social, and Cultural Status of the Basque Country had the greatest influence in students’ PISA competence scores. Language of instruction on the other hand, was not found to have statistically significant results

El rol de terceras partes en el proceso de conciliación de relaciones bilaterales colombo - ecuatorianas tras el conflicto en Angostura

The rupture of bilateral relations between Ecuador and Colombia took place after the conflict in Angostura, which became a critical violation of sovereignty and a figure of International Law. The war effort carried out by the Colombian government Álvaro Uribe in 2008 produced the most severe diplomatic crisis with its neighbor Ecuador. Consequently, the actions of international agencies to find peaceful solutions began to develop with the Carter Center and the Binational Dialogue Group, the Organization of American States, and the United Nations playing a significant role. In this way, their strategies and methods of cooperation and unity for the States' parties to the conflict are beginning to execute, thus having a relevant role as third parties involved in the process of reconciliation between nations.La ruptura de las relaciones bilaterales entre Ecuador y Colombia, se produce tras el conflicto en Angostura, el cual se convirtió en una crítica violación a la soberanía y a la figura del Derecho Internacional. La acción bélica realizada por el gobierno colombiano Álvaro Uribe en el año 2008, produjo una grave crisis diplomática con su vecino Ecuador. Consecuentemente, el accionar de organismos internacionales para encontrar soluciones pacíficas se comenzó a desarrollar, teniendo un rol significante el Centro Carter y el Grupo Binacional de Diálogo, la Organización de Estados Americanos y las Naciones Unidas. De esta manera sus estrategias y métodos de cooperación y unidad para los Estados parte del conflicto se empiezan a ejecutar teniendo así un rol relevante como terceras partes involucradas en el proceso de conciliación entre las naciones

The role of aversiveness in the relationship between intolerance of uncertainty and inflexible avoidance

The study of avoidance behaviour is considered relevant to improve our understanding of anxiety disorders, which are commonly characterized by the presence of undue avoidance behaviours. Flores et al. (2018) found evidence that Prospective Intolerance of Uncertainty (P-IU) is associated with inflexible avoidance behaviour. Specifically, healthy participants learned in a free-operant discriminative task to avoid an aversive sound, and were tested in extinction to measure the sensitivity of avoidance responses to the devaluation of the sound aversiveness. The results showed that an increase in P-IU was positively associated with insensitivity to outcome devaluation. This association was still significant even when trait anxiety was controlled for. These results suggested that PIU may be a vulnerability factor for inflexible avoidance. However, in a recent replication, we found that the relationship between P-IU and inflexible avoidance was moderated by the participants ratings of outcome aversiveness. Specifically, the significant association between PIU and insensitivity to outcome devaluation was found to be conditional upon high aversiveness ratings.Universidad de Málaga.

Partial extinction and reinstatement

Fear extinction is not permanent but more vulnerable than the original fear memory, as relapse phenomena have traditionally shown. Partial extinction has been proposed as a strategy that may serve to mitigate relapses. Partial extinction differs from the standard procedure as it includes the occasional presentation of CS-US trials at the beginning of the extinction training. The present experiment, using an aversive differential conditioning procedure, evaluates whether partial extinction can reduce reinstatement, a specific form of relapse. The results showed that partial extinction did not mitigate reinstatement but proved effective to diminish the magnitude of the US expectation after a first reacquisition trial in a final test phase. The results reported are more consistent with theories that conceives extinction as the acquisition of new inhibitory learning rather than the erasure of the original conditioning.Universidad de Málaga.

Estimates of the likelihood of threats are related to intolerance of uncertainty and learning

In the present experiment, we assessed the relationship between intolerance of uncertainty and expectancy ratings of threats both in the presence of conditioned stimuli (CS) that signalled the delivery of an aversive unconditioned stimulus (US), and after making an avoidance response. Participants learned the relationship between several pictures serving as CSs and an aversive sound serving as the US, and learned to avoid the US through a procedure including alternating pavlovian and negative reinforcement training phases. Expectancy ratings were measured on every training trial. Our results only showed a significant association between intolerance of uncertainty and expectancy ratings made after avoidance responses. This association was found only when the avoidance response was made in the presence of CSs signalling that the aversive sound was avoidable. The increase in intolerance of uncertainty was related to lower expectancy ratings in good learners, and to higher expectancy ratings in bad learners. These results are tentatively explained by invoking a view of intolerance of uncertainty as an exaggerated reaction to uncertainty aimed at learning to avoid threats.Universidad de Málaga.

Studying habit acquisition with an avoidance learning task

Afiliaciones: Universidad de Málaga and Instituto de Investigación Biomédica de Málaga (IBIMA), Spain Universidad de Málaga, Spain University of Leuven, BelgiumThe study of habit acquisition and expression is considered relevant to improve our understanding of mental disorders characterised by the presence of compulsive or incontrollable behaviours. Most studies on habit learning, both in animals and in humans, are based on positive reinforcement paradigms. However, the compulsions and habits involved in some mental disorders may be better understood as avoidance behaviours, which involve some peculiarities such as anxiety states that have been shown to promote habitual responses. Consequently, we studied habit acquisition by using a free-operant discriminated avoidance procedure. Participants learned to avoid an aversive noise presented either to the right or to the left ear by pressing two different keys. After a devaluation phase where participants could reduce the volume of the noise presented to one of the ears, participants went through a test phase identical to the avoidance learning phase except for the fact that the noise was never administered. Habit acquisition was inferred by comparing the rate of responses to the stimulus signalling the devalued reinforcer and to the stimulus signalling the non-devalued reinforcer. Habitual responses would entail the absence of differences between the referred conditions. Finally, we discuss the theoretical and clinical implications of the results obtained.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Partial extinction did not diminish spontaneous recovery after 24-hour retention interval

Fear extinction is not permanent but it may suffer from different forms of relapse. One strategy potentially useful to diminish relapse is the partial extinction treatment, according to which, extinction may be potentiated if a gradual and sparse number of CS-US pairings are introduced within the extinction treatment. The present study, using a differential fear conditioning paradigm, tries to evaluate the efficacy of partial extinction to reduce a specific form of relapse, spontaneous recovery, after a 24 h. retention interval. The results showed that partial extinction did not diminish spontaneous recovery when compared with standard extinction. From a theoretical point of view, the pattern of results found was more consistent with the idea that extinction entails the acquisition of new knowledge than with the idea that there are conditions in which extinction entails the erasure of the original acquisitionUniversidad de Málaga.

Using data science as a community advocacy tool to promote equity in urban renewal programs: An analysis of Atlanta's Anti-Displacement Tax Fund

Cities across the United States are undergoing great transformation and urban growth. Data and data analysis has become an essential element of urban planning as cities use data to plan land use and development. One great challenge is to use the tools of data science to promote equity along with growth. The city of Atlanta is an example site of large-scale urban renewal that aims to engage in development without displacement. On the Westside of downtown Atlanta, the construction of the new Mercedes-Benz Stadium and the conversion of an underutilized rail-line into a multi-use trail may result in increased property values. In response to community residents' concerns and a commitment to development without displacement, the city and philanthropic partners announced an Anti-Displacement Tax Fund to subsidize future property tax increases of owner occupants for the next twenty years. To achieve greater transparency, accountability, and impact, residents expressed a desire for a tool that would help them determine eligibility and quantify this commitment. In support of this goal, we use machine learning techniques to analyze historical tax assessment and predict future tax assessments. We then apply eligibility estimates to our predictions to estimate the total cost for the first seven years of the program. These forecasts are also incorporated into an interactive tool for community residents to determine their eligibility for the fund and the expected increase in their home value over the next seven years.Comment: Presented at the Data For Good Exchange 201

Ex-vivo perfusion bioassay : an excellent technique to measure the bioactivity of inhalable insulin coated microcrystals

Purpose: To measure the bioactivity of inhalable insulin coated microcrystals using a perfusion bioassay that measures its vasodilatory effect on smooth muscle arterial tissue. Methods: The bioactivity of an insulin protein coated microcrystal (PCMC), a potential candidate for pulmonary drug delivery and commercial insulin was determined on a Danish Myo Tech P110 pressure myograph system. 12 week old Mesenteric resistance arteries from Male Wistar rats were isolated and immersed in a physiological salt solution (PSS) and attached to 2 opposing hollow glass micro-cannula (outer diameter 80 microns). The PSS was gradually warmed to 37°C (at a pressure less than 5mm Hg) for 1hr. Subsequently the pressure was increased up to 40mm Hg over a period 15 minutes and equilibrated for a further 15 minutes after gassing with 95%O2 / 5%CO2 to achieve a pH of 7.4 at 37°C. After normalisation by two washes of 123mM KCl and exposure to 1-10mM noradrenaline the arteries were exposed intraluminally to each insulin preparation by gradual infusion directly into the lumen via a fetal microcannulae inserted to the tip of the glass mounting cannula, at a constant pressure. Results: The preliminary results (full cummulative response curve yet to be determined) demonstrate insulin mediated relaxation to noradrenaline preconstriction. The level of constriction drops from 100% to 42% as the concentration of insulin increases from -11 to -9 Log M for the PCMC compared with a drop from 100 % to 65% for the commercial insulin preparation. However the more potent vasodilatory effect found for the insulin PCMC is more likely to be a result of variance introduced in each dilution step than a real increase in potency. Conclusion: The perfusion bioassay technique provides an excellent method of measuring insulin bioactivity and indicates the insulin loaded on the microcrystal support is fully active

Host Plant Influences on Performance and Haplotype Diversity of Dalbulus maidis, a Specialist Herbivore of Zea

In one study, a suite of plants from the maize genus Zea L. (Poaceae) and the specialist herbivore Dalbulus maidis (DeLong and Wolcott, 1923) (Hemiptera: Cicadellidae) were used to test the hypotheses that anti-herbivore defenses are affected by plant life-history evolution and human intervention through domestication and breeding for high yield. The suite of Zea host plants included one Mexican commercial hybrid maize Zea mays ssp. mays L., a landrace variety of maize, two populations of Balsas teosinte (Zea mays ssp. parviglumis Iltis & Doebley), and perennial teosinte (Z. diploperennis Iltis, Doebley & Guzman). This suite of host plants includes three Transitions evident within the genus Zea: life history form perennial to annual life cycle evident between perennial teosinte and Balsas teosinte, domestication transition from wild annual to domesticated annual evident between Balsas teosinte and landrace maize, and; breeding transition from landrace cultivar to a hybrid cultivar. The transitions were correlated with differences in plant defenses, as indicated by corn leafhopper performance. Results showed a performance gradient, suggesting a pattern in which plant defense is stronger in perennial than annual plants, Balsas teosinte than landrace maize, and in landraces than in hybrid maize. Furthermore, results suggested that domesticated maize would be the least defended, most suitable host for corn leafhopper. In a second study, haplotype diversity was assessed to address structuring and interconnectedness among samples of corn leafhopper collected in the southwestern region of Mexico to address microevolution. The geographic focus of the study was maintained within an area encompassing the presumed centers of radiation of Dalbulus and its host genus Zea, and of maize domestication. Samples were complemented with samples of corn leafhopper sequences available at GenBank. Results revealed seven haplotypes from three host plants within Zea: perennial teosinte, Balsas teosinte, and maize. Furthermore, genetic differentiation was present and haplotype diversity appears to correlate with differences in genetic structure between perennial teosinte and maize. One haplotype was found to be present throughout all sites, which appears to parallel the spread of maize cultivation. As maize cultivation spread beyond its area of domestication, corn leafhoppers colonized perennial teosinte, further suggesting that subsequent decreases in maize cultivation in perennial teosinte habitat created a refuge where perennial teosinte- adapted haplotypes could persist. Altogether, my research suggests that the combination of historical expansion of maize cultivation expansion and the weaker anti-herbivore defenses associated within maize domestication appears to have favored genotypes particularly adapted for exploiting maize
