A failed but useful constitution-making process: How Bachelet’s process contributed to constitution-making in Chile
(2023) García García, José Francisco
This article shows how failed constitutional proposals may contribute to future constitution-making processes by exploring the relationship between the recently failed Chilean constitution-making process (2019–22) and the previous unsuccessful one led by former President Michelle Bachelet (2015–17). Comparative constitutional scholars are yet to fully understand how constitutional failures of this kind can take place, and Bachelet’s process has not received the attention it should. This article fills that gap by showing how both processes were driven by shared principles initially set by Bachelet. It also shows how those principles may serve as a blueprint for future constitutional changes in Chile. Bachelet had campaigned on the basis that any constitutional replacement attempt should be participatory, institutional and democratic – all ideas that have remained popular in Chile’s political landscape. Those ideas have served the purpose of both reducing transaction costs among constitutional negotiators and securing large compromises in polarized political scenarios.
Adaptation of a mobile app for early anxiety and depression intervention in university students in Chile: participatory study
(2023) Lira, Daniela; Caviedes, Patricio; Martínez, Vania
The high prevalence of mental health problems among university students poses a challenge when developing effective interventions, with digital technologies emerging as a potential resource to address this problem. The inclusion of student input in the design and development of such interventions is critical to improving their impact. This study contributed to the initial phase of a research project that aims to adapt and evaluate the feasibility and acceptability of an early intervention for anxiety and depression based on digital technologies for university students. Three participatory workshops were conducted with 13 university students in Chile to inquire about the features and content that a mental health mobile app should include to meet their needs and preferences. The workshop transcripts were analysed using inductive thematic analysis. The results of this study highlight the value of modifications such as the personalisation of some features of the app. The students recommended incorporating topics related to university life and the possibility of contacting a mental health professional, as well as the inclusion of peer interaction or other forms of support.
Chile’s failed constitutional intent: Polarization, fragmentation, haste and delegitimization
(2023) Palanza, María Valeria; Sotomayor Valarezo, Patricia
This article suggests that the conditions under which the Chilean constitutional process of 2021–22 undertook its task held the seeds of its doom. Constitutional conventions are always tasked with reaching agreements on the controversial allocation of decision rights, and doing so is no simple feat. The Chilean process combined (1) very dispersed preferences regarding the problems the new constitution should solve and the institutions to best enable solutions, with (2) a brief timeframe to allow for agreements to emerge, aggravated by (3) a composition of the Convention that was dominated by independents lacking experience in legislative bargaining, and (4) a severe disenchantment of the population with parties and politics as the backdrop. Together, these hurdles proved impossible to overcome. Despite the notorious political achievements of the Committee we study here, the proposal that came out of Chile’s Constitutional Convention in 2021 was plagued by controversy and a negative perception of the Convention’s work, and was ultimately rejected by the people.
Counting independent sets in amenable groups
(2023) Briceño Domínguez, Raimundo José
Given a locally finite graph Γ, an amenable subgroup G of graph automorphisms acting freely and almost transitively on its vertices, and a G-invariant activity function λ, consider the free energy fG(Γ,λ) of the hardcore model defined on the set of independent sets in Γ weighted by λ. Under the assumption that G is finitely generated and its word problem can be solved in exponential time, we define suitable ensembles of hardcore models and prove the following: if ∥λ∥∞<λc(Δ), there exists a randomized ϵ-additive approximation scheme for fG(Γ,λ) that runs in time poly((1+ϵ−1)|Γ/G|), where λc(Δ) denotes the critical activity on the Δ-regular tree. In addition, if G has a finite index linearly ordered subgroup such that its algebraic past can be decided in exponential time, we show that the algorithm can be chosen to be deterministic. However, we observe that if ∥λ∥∞>λc(Δ), there is no efficient approximation scheme, unless NP=RP. This recovers the computational phase transition for the partition function of the hardcore model on finite graphs and provides an extension to the infinite setting. As an application in symbolic dynamics, we use these results to develop efficient approximation algorithms for the topological entropy of subshifts of finite type with enough safe symbols, we obtain a representation formula of pressure in terms of random trees of self-avoiding walks, and we provide new conditions for the uniqueness of the measure of maximal entropy based on the connective constant of a particular associated graph.
Differences in clinical aspects of human cystic echinococcosis caused by Echinococcus granulosus sensu stricto and the G6 genotype in Neuquén, Argentina
(2023) Debiaggi, María Florencia; Álvarez Rojas, Cristián Andrés; Lazzarini, Lorena Evelina; Calfunao, Daniel; Titanti, Paola; Calanni, Liliana; Iacono, Marisa; Soriano, Silvia Viviana; Deplazes, Peter; Pierangeli, Nora Beatriz
Most human cystic echinococcosis (CE) cases worldwide are attributed to Echinococcus granulosus sensu stricto (s.s), followed by the G6 and G7 genotypes. While E. granulosus s.s. has a cosmopolitan distribution, the G6 genotype is restricted to areas where camels and goats are present. Goats are the primary livestock in the Neuquén province in Argentina where the G6 genotype has been reported to be responsible for a significant percentage of CE human cysts genotyped. In the present study, we genotyped 124 Echinococcus cysts infecting 90 CE-confirmed patients. Echinococcus granulosus s.s. was identified in 51 patients (56.7%) with 81 cysts and the G6 genotype in 39 patients (43.3%) harbouring 43 cysts. Most CE cases ≤18 years were male suggesting pastoral work could be a risk factor for the infection. Echinococcus granulosus s.s. was significantly found more frequently in the liver (32/51 patients) and the G6 genotype in the lungs and extrahepatic localizations (27/39). The patients infected with E. granulosus s.s., presented up to 6 cysts while patients infected with G6 presented a maximum of 2. The diameter of lung cysts attributed to E. granulosus s.s. was significantly larger compared to lung cysts from G6. Following the WHO ultrasound classification of liver cysts, we observed inactive cysts in 55.6% of G6 cysts and only 15.3% of E. granulosus s.s cysts. In conclusion, we provide evidence of differences in clinical aspects of CE caused by E. granulosus s.s. and the G6 genotype of E. granulosus s.l. complex infecting humans.
Do fiscal transfers affect local democracy?: lessons from Chilean Municipalities
(2023) Alberti, Carla; Díaz Rioseco, Diego; Riveros, Ignacio
Extant literature concurs that fiscal transfers affect local democracy when they grant subnational governments nontax revenue. Yet there is nonetheless a mismatch between this concept and existing measures, which consider the whole transfers local governments receive, including both tax and nontax revenue. This article studies the Fondo Común Municipal (FCM), the most important intergovernmental grant in Chile, and provides a novel measure of nontax revenue. It uses this measure alongside the whole FCM transfer to test the rentier hypothesis. On the one hand, it shows that both measures increase the incumbent party vote share, although the effect of our measure is smaller. On the other hand, it finds that the FCM transfer has an impact on the probability of reelection and the competitiveness of elections, but this effect disappears when using our measure. Overall, the findings suggest that rents from transfers do not lead to strong electoral dominance in unitary states.
Elite non-cooperation in polarized democracies: Constitution-making deferral, the entry referendum and the seeds of the Chilean failure
(2023) García-Huidobro, Luis Eugenio
This article extends the study of the shortcomings of the constitution-making design that contributed to the failure of the Chilean process by addressing a largely overlooked aspect: the 2020 entry referendum. By placing two competing constitution-making models on the ballot, the political elites delegated to the voters a highly conflictual aspect of the process design that prevented cooperation among them. While some political parties approached the disagreements placed on the ballot as an opportunity to reopen discussions already settled by the 2019 Agreement, others interpreted the move as a cancellation of the political insurance contained in the Agreement. This exacerbated the existing polarization among political elites and imperiled prospects for the success of the process.
How do constitution-making processes fail? The case of Chile’s Constitutional Convention (2021–22)
(2023) Verdugo, Sergio; García-Huidobro, Luis Eugenio
This introduction to the symposium ‘How do Constitution-Making Processes Fail? The Case of Chile’s Constitutional Convention (2021–22)’ situates the project in the field of constitution-making, provides context regarding the Chilean case, summarizes some possible explanations for the failure, and describes how each article contributes to the symposium as a whole.
Intersecting the torsion of elliptic curves
(2023) García-Fritz, Natalia; Pasten, Hector
Bogomolov and Tschinkel [‘Algebraic varieties over small fields’, Diophantine Geometry, U. Zannier (ed.), CRM Series, 4 (Scuola Normale Superiore di Pisa, Pisa, 2007), 73–91] proved that, given two complex elliptic curves E1 and E2 along with even degree-2 maps πj: Ej → P1 having different branch loci, the intersection of the image of the torsion points of E1 and E2 under their respective πj is finite. They conjectured (also in works with Fu) that the cardinality of this intersection is uniformly bounded independently of the elliptic curves. The recent proof of the uniform Manin–Mumford conjecture implies a full solution of the Bogomolov–Fu–Tschinkel conjecture. In this paper, we prove a generalisation of the Bogomolov–Fu–Tschinkel conjecture whereby, instead of even degree-2 maps, one can use any rational functions of bounded degree on the elliptic curves as long as they have different branch loci. Our approach combines Nevanlinna theory with the uniform Manin–Mumford conjecture. With similar techniques, we also prove a result on lower bounds for ranks of elliptic curves over number fields.
Model sets with Euclidean internal space
(2023) Allendes Cerda, Mauricio; Coronel, Daniel
We give a characterization of inter-model sets with Euclidean internal space. This characterization is similar to previous results for general inter-model sets obtained independently by Baake, Lenz and Moody, and Aujogue. The new ingredients are two additional conditions. The first condition is on the rank of the abelian group generated by the set of internal differences. The second condition is on a flow on a torus defined via the address map introduced by Lagarias. This flow plays the role of the maximal equicontinuous factor in the previous characterizations.
Motivation Alignment, Historical Cleavages, and Women's Suffrage in Latin America
(2022) Castillo Carniglia, Isabel
Calculations of the electoral effects of incorporating new voters and beliefs on how inclusion alters gender hierarchies constitute two central motivations of decision makers when facing the prospect of suffrage reform. In contrast to the dominant electoral approach, by focusing on the case of early (before World War II) women’s suffrage in Latin America, I show that both these motivations are necessary and need to align for reform to occur. To explain the (mis)alignment of electoral calculations and social order concerns in Latin America, I consider the region’s historical oligarchic–anti-oligarchic cleavage structure, which is rooted in overlapping class and religious divisions. In most cases, this cleavage produced contradictory motivations and led actors to block women’s enfranchisement. Only cases of weak cleavages or low politicization of the issue had early reform. To illustrate the argument, this article uses process tracing to analyze Uruguay and Ecuador as successful early reformers and Peru as a negative case.
Multilateralism and the Global Co-Responsibility of Care in Times of a Pandemic: The Legal Duty to Cooperate
(2023) Campos, Thana Cristina de
This article challenges the orthodox view of international law, according to which states have no legal duty to cooperate. It argues for this legal duty in the context of COVID-19, based on the ethical principles of solidarity, stewardship, and subsidiarity. More specifically, the article argues that states have a legal duty to cooperate during a pandemic (as solidarity requires); and while this duty entails an extraterritorial responsibility to care for and assist other nations (as stewardship requires), the legal duty to cooperate still allows states to attend first to the basic needs of those under their own jurisdiction—namely, fellow nationals and residents (as subsidiarity requires). The article provides a definition and philosophical justifications for this legal duty that are lacking in the literature by examining its application to a current COVID-19 controversy: namely, states’ responsibility to assist other countries in greater need by, inter alia, exporting at a discount or donating scarce COVID-19 treatments (including vaccines). In providing a principled tripartite account of pandemic governance, this conceptual and normative article offers a new lens for debating the potential international treaty for pandemic prevention, preparedness, and response that has now been drafted and is under negotiation at the World Health Assembly, by responding to the recent backlash against multilateralism by substantiating global co-responsibilities in times of pandemics and beyond.
Objective burden, caregiver psychological distress, and patient religion and quality of life are associated with high-intensity burden of care among caregivers of advanced cancer patients in a Latino population
(2023) Soto Guerrero, Sebastián; Palacios, Josefa; Langer, Paola; Carrasco, Cecilia; Tupper-Satt, Laura; González-Otaíza, Marcela; Rodríguez Núñez, Alfredo; Pérez Cruz, Pedro
Objectives: Family caregivers (FCs) of cancer patients experience burden of care. The aims of this study are to describe the caregiving phenomenon among FCs of advanced cancer patients in a Latino community and to identify caregiver and atient characteristics associated with high-intensity subjective caregiver burden. Methods: In this cross-sectional study, advanced cancer patient–caregiver dyads assessed at a Palliative Care Unit in Santiago, Chile, enrolled in a longitudinal observational study were included. FCs completed questions to describe the caregiving phenomenon and surveys to assess burden of care, psychological distress, and perception of patients’ symptoms; patients completed surveys to assess physical distress and quality of life (QOL). We explored associations between high-intensity subjective caregiver burden with caregiver and patient variables. Results: Two hundred seven dyads were analyzed. FCs were on average 50 years old and 75% female. Thirty-two percent of FCs experienced high-intensity subjective burden of care. Eighty two percent of FCs took care of the patient daily and 31% took care of the patient alone. In univariate analysis, high-intensity caregiver burden was associated with caregiver depression (59% vs. 27%; p < 0.001), anxiety (86% vs. 67%; p = 0.003), caring for the patient alone (45% vs. 24%; p = 0.002), perception of patient symptom distress, patient religion, and worse patient QOL (mean [standard deviation] 58 [33] vs. 68 [27]; p = 0.03). In multivariate analysis, FC depression (OR [95% confidence interval] 3.07 [1.43–6.60]; p = 0.004), anxiety (3.02 [1.19–7.71]; p = 0.021), caring for the patient alone (2.69 [1.26–5.77]; p = 0.011), caregiver perception of patient’s fatigue (1.26 [1.01–1.58]; p = 0.04), and patient’s religion (3.90 [1.21–12.61]; p = 0.02) were independently associated with caregiver burden. Significance of results: FCs of advanced cancer patients in a Latino community frequently experience high-intensity burden of care and are exposed to measures of objective burden. High-intensity burden is associated with both caregiver and patient factors. Policies should aim to make interventions on patient–caregiver dyads to decrease caregiving burden among Latinos.
On the fibres of an elliptic surface where the rank does not jump
(2022) Caro Reyes, Jerson; Pastén Vásquez, Héctor
For a nonconstant elliptic surface over P1 defined over Q , it is a result of Silverman [‘Heights and the specialization map for families of abelian varieties’, J. reine angew. Math. 342 (1983), 197–211] that the Mordell–Weil rank of the fibres is at least the rank of the group of sections, up to finitely many fibres. If the elliptic surface is nonisotrivial, one expects that this bound is an equality for infinitely many fibres, although no example is known unconditionally. Under the Bunyakovsky conjecture, such an example has been constructed by Neumann [‘Elliptische Kurven mit vorgeschriebenem Reduktionsverhalten. I’, Math. Nachr. 49 (1971), 107–123] and Setzer [‘Elliptic curves of prime conductor’, J. Lond. Math. Soc. (2) 10 (1975), 367–378]. In this note, we show that the Legendre elliptic surface has the desired property, conditional on the existence of infinitely many Mersenne primes.
Resting energy metabolism and sweet taste preference during the menstrual cycle in healthy women
(2023) Malo-Vintimilla, Lorena; Aguirre Polanco, Carolina; Vergara, Angie; Fernández-Verdejo, Rodrigo; Galgani, Jose E.
Differences in blood concentration of sex hormones in the follicular (FP) and luteal (LP) phases may influence energy metabolism in women. We compared fasting energy metabolism and sweet taste preference on a representative day of the FP and LP in twenty healthy women (25·3 (SD 5·1) years, BMI: 22·2 (SD 2·2) kg/m2) with regular self-reported menses and without the use of hormonal contraceptives. From the self-reported duration of the three prior menstrual cycles, the predicted FP and LP visits were scheduled for days 5–12 and 20–25 after menses, respectively. The order of the FP and LP visits was randomly assigned. On each visit, RMR and RQ by indirect calorimetry, sweet taste preference by the Monell two-series forced-choice tracking procedure, serum fibroblast growth factor 21 by a commercial ELISA (FGF21, a liver-derived protein with action in energy balance, fuel oxidation and sugar preference) and dietary food intake by a 24-h dietary recall were determined. Serum progesterone and oestradiol concentrations displayed the expected differences between phases. RMR was lower in the FP v. LP (5042 (SD 460) v. 5197 (SD 490) kJ/d, respectively; P = 0·04; Cohen effect size, drm = 0·33), while RQ showed borderline significant higher values (0·84 (SD 0·05) v. 0·81 (SD 0·05), respectively; P = 0·07; drm = 0·62). Also, in the FP v. LP, sweet taste preference was lower (12 (SD 8) v. 16 (SD 9) %; P = 0·04; drm = 0·47) concomitant with higher serum FGF21 concentration (294 (SD 164) v. 197 (SD 104) pg/ml; P < 0·01; drm = 0·66). The menstrual cycle is associated with changes in energy expenditure, sweet taste preference and oxidative fuel partitioning.
Rethinking Post-authoritarian Chile Through its Popular Music
(2023) Party Tolchinsky, Daniel
This article is a study of Chilean popular music produced during the 1990s, the first decade following the end of the Pinochet dictatorship. The return of democracy and a period of strong economic growth contributed to a boom in the Chilean music industry. A wealth of music was recorded and the opportunities for listening to live music multiplied. The article's main objectives are to illuminate the ways in which Chilean popular music addressed democracy's inspiring promises and frustrating limits and to consider how Chileans used popular music to foster new post-authoritarian identities. First, it argues that music was used to reclaim national symbols that had been coopted by the dictatorship. Second, it considers the music of two generations of musicians who returned to the country after living in exile. Finally, it focuses on punk and hip-hop, the styles that produced the most significant examples of protest music in the post-authoritarian period.
The IDI, The ILA, and their Impact on the Institutionalization of International Law in the Americas: Resonances and Dissonances
(2023) Scarfi, Juan Pablo
The Institut de Droit International (IDI) and the International Law Association (ILA) have bequeathed complex and contradictory legacies to the Americas. This essay explores both the resonances and the dissonances that the formation of the IDI, and to a lesser extent, the ILA, had in the institutionalization of the modern discipline of international law in the Americas. On the one hand, the IDI's establishment as an elite Eurocentric organization with a missionary imperial approach to the promotion and reform of international law, generated resonances across the Americas, inspiring the creation of the American Institute of International Law (AIIL). On the other hand, the AIIL emerged as a reaction to the IDI, insofar as the former promoted juridical values based on the idea of American international law and a distinctive sense of U.S. and continental legal exceptionalism. The essay argues that the institutionalization of international law in the Americas was both inspired by the Eurocentric imperial and elitist legal approach promoted by the IDI, and the desire to forge a distinctive Western Hemispheric counterpart: a continental American international law.
Trader Competition in Fragmented Markets: Liquidity Supply Versus Picking-Off Risk
(2023) Bernales, Alejandro; Garrido, Nicolas; Sagade, Satchit; Valenzuela Bravo, Marcela; Westheide, Christian
By employing a dynamic model with two limit order books, we show that fragmentation is associated with reduced competition among liquidity suppliers and lower picking-off risk of limit orders. Due to these countervailing channels, the impact of fragmentation on liquidity and welfare differs with asset volatility: When volatility is high (low), liquidity and aggregate welfare in a fragmented market are higher (lower) than in a single market. However, fragmentation always shifts welfare away from agents with exogenous trading motives and toward intermediaries. We empirically corroborate our model’s predictions about liquidity. Our model reconciles the mixed results in the empirical literature.
Uneven States, Unequal Societies, and Democracy’s Unfulfilled Promises: Citizenship Rights in Chile and Contemporary Latin America
(2023) Luna, Juan Pablo; Medel, Rodrigo M.
In contemporary Latin America, deep-seated social discontent with political elites and institutions has been, paradoxically, the counterpart of democratic stability and resilience. This paradox suggests that scholarly assessments of democracy are, at least partially, at odds with citizens’ own views of democracy. This article thus develops a framework to describe citizens’ everyday experience with civil, political, and social entitlements associated with democracy. It introduces the framework by analyzing the structural underpinnings of democratic discontent in Chile and then applying it to the analysis of perceived citizenship entitlements in 18 countries, using the AmericasBarometer data. Significant variance is observed across time and both across and within countries. The descriptive findings also imply that only a (declining) minority of Latin American citizens feel fully entitled to civil, political, and social citizenship rights. We advocate the need to bring the demand side of democracy back to the analysis of democratic shortcomings and crises.
