Still on the Santiago Round Table: considerations on the concept of territory and its reverberations

The article is part of a movement to commemorate the fiftieth anniversary of the Roundtable of Santiago de Chile, to make considerations around the uses and meanings, presence and absence of the debate on territory and museums established since then. The reflections are oriented towards understanding and problematizing how terms related to community, place, area, territory and their semantic and notional relatives were, and are, mobilized. The exercise is conducted by looking at the Declaration of Santiago de Chile, from 1972, in dialogue with the literature that followed and continues to inspire practices and ideas in the museum field. It argues that the territorial approach was incipient in that historical context and that, in recent decades, the notional set that orbits the territory category has emerged as an important analytical category for museum actions. Due to this, it defends the necessary effort of dialogue with territorial literature – essentially multidisciplinary – with the aim of instrumentalizing practices in the museum field and continuing to feed new theoretical systematizations.

Morphological Characteristics of the Double Mental Foramen and Its Relevance in Clinical Practice: An Observational Study.

The mental foramen (MF) is an opening found bilaterally on the anterolateral aspect of the mandible; it can be round or oval and have different diameters. One of the anatomical variants of the jaw is the presence of an accessory mental foramen (AMF). These are usually smaller than the MF and can be located above, below, or to the sides of the main MF. The objective of this study was to recognize the presence of AMF in dry jaws of the Chilean population and collect information about its clinical relevance reported in the literature. In this descriptive observational study, we have collected dried jaws obtained from three higher education institutions in Santiago de Chile, from the Department of Morphology of the Andrés Bello University, the Normal Human Anatomy Unit of the University of Santiago, and the Human Anatomy pavilion from the Faculty of Medicine of the Finis Terrae University. The samples for this research were obtained by convenience, and the observation of the jaws was carried out in the human anatomy laboratories of each institution by three evaluators independently, and a fourth evaluator was included to validate that each evaluation was correct. The sample for this research came from 260 dry jaws, showing the following findings from the total jaws studied, and to classify as an accessory MF, it will be examined and measured so that it complies with what is declared in the literature as the presence of AMF, which is between 0.74 mm. and 0.89 mm. There were 17 studies included with a sample that fluctuated between 1 and 4000, with a cumulative total of 7946 and an average number of jaws analyzed from the studies of 467.4, showing statistically significant differences between the means with the sample analyzed in this study; p = 0.095. For the cumulative prevalence of the presence of AMF, this was 3.07 in this study, and in the compared studies, the average of AMF was 8.01%, which did not present a statistically significant difference; p = 0.158. Regarding the presence of variants of unilateral AMF, this occurred in five jaws, which is equivalent to 1.84% in the sample of this study, while in previous studies, it was 7.5%, being higher on the left side than on the right. The presence of AMF is a variant with high prevalence if we compare it with other variants of the jaw. Knowledge of the anatomy and position of the AMF is crucial to analyze different scenarios in the face of surgical procedures or conservative treatments of the lower anterior dental region.

Microeconomic analysis of ridesourcing market regulation policies

We develop a microeconomic model of competition between ridesourcing, public transport, and cruising taxis to analyse how alternative ridesourcing regulation policies affect not only the ridesourcing service but also other modes of transport. To maximise social welfare in a framework with congestion externalities, we analyse three alternative regulation policies (i) a charge as a percentage of the ridesourcing trip fare (ii) a fixed charge per ridesourcing trip, and (iii) a fixed charge per ridesourcing vehicle. A randomised search algorithm is programmed and simulations are performed considering the base case of the Metropolitan Region of Santiago de Chile. We find that for the case of speeds below 9 km/h, the market power of the platform is dominated by the congestion externality effect, which leads to an optimum where the regulator charges a tax to the platform. In turn, waiting time for ridesourcing increases, but congestion decreases. Lower congestion scenarios lead to a ridesourcing subsidy, in which the regulation policy increases the number of ridesourcing drivers and reduces waiting time, at the cost of increasing congestion. For a given scenario (either low-congestion or high-congestion), we find that the profits of the agents involved (ridesourcing platform and drivers, taxi drivers, and bus operator) are sensitive to the type of regulation applied, however the total social benefit and consumer surplus are largely insensitive to the regulation adopted, therefore policymakers could take into account, for instance, the effects on the financial situation of the public transport sector when deciding which type of regulation instrument to apply to the ridesourcing sector.

Personal Ethics and Ethical Leadership in The Face of The Resolution of Dilemmas and Problematic Situations in Chilean Graduates

Objective: The objective of this study is to investigate the relationship between personal ethics and deontological leadership in Chilean graduates, with the purpose of determining whether a high level of personal ethics in leaders influences the resolution of moral dilemmas and problematic situations in the institutional environment. Theoretical Framework: The research is based on concepts and theories about professional ethics, deontological leadership, and university ethics training. Theories and models such as Applied Ethics, Business Ethics and the deontological theory of ethics stand out. Method: A quantitative methodology with a survey design was adopted. 207 graduates of various careers from the Universidad Austral de Chile participated. Three instruments were used: the Ethical Leadership Questionnaire, the Ethical Dilemmas of Business Culture Questionnaire, and the Personal Ethics survey of collaborators. Data were analyzed with SPSS Statistics 23 and SPSS AMOS 23, performing exploratory and confirmatory factor analyzes. Results and Discussion: The results revealed that a high level of personal ethics is crucial to exercise effective deontological leadership. Significant differences in ethical perception between genders and ages were identified, suggesting that women and older professionals better manage ethical dilemmas. A negative correlation was observed between tolerance to unethical behaviors and the ability to solve ethical dilemmas. Implications of Research: Practical implications include the need to incorporate rigorous ethical training into university curricula to develop ethical leaders. Theoretically, the study contributes to the understanding of the relationship between personal ethics and deontological leadership, proposing that personal ethics is an essential precursor for ethical leadership in organizations. Originality/Value: This study contributes to the literature by empirically demonstrating the importance of personal ethics in deontological leadership. Their innovative approach and the discoveries made can influence training and professional practices in the educational and business field.

DOCTORAL PROGRAM IN MEDICAL SCIENCES ASSOCIATED WITH A SPECIALTY. A HISTORY CLOSELY LINKED TO THE CHILEAN ACADEMY OF MEDICINE

The Doctoral Program in Medical Sciences (DPMC) associated with a specialty of the Faculty of Medicine of Universidad de Chile is an academic development project that aims to train specialists with a PhD degree, who are inserted in clinical centers and have the ability to respond questions of medical interest with a translational basis, putting the generation of knowledge at the service of patients. Universidad de Chile hopes that the graduates of this program will be the basis of the academic turnover of future generations. The DPMC was created in 2000, to date (2023), 85 students have entered, 46 have graduated, 8 have withdrawn and there are 31 current students. Sixty-five per cent of the graduates work as academics at the Faculty of Medicine of Universidad de Chile, with outstanding activity as specialists, teachers and researchers, incorporated into the different Advanced Clinical Research Centers (CICAs) that the faculty has created in different hospitals. Fifty-four per cent of them have been or are principal investigators of competitive projects: FONDECYT, FONDEF, FONIS, with one or more projects awarded, depending on the time since their degree, with an average of 55 publications/year for the defined group. After 23 years of uninterrupted operation, the DPMC is a consolidated, unique, accredited, successful program, financed by Universidad de Chile, sustainable, a pillar of the academic development of the Faculty of Medicine, which as it grows will allow the CICA network to be strengthened and will contribute to the creation of knowledge at the service of the patients and the country.

Between Struggle, Forgetfulness, and Placemaking: Meanings and Practices among Social Groups in a Metropolitan Urban Park

Urban spatial segregation in Santiago de Chile, a prevalent feature of Latin American cities, underscores socioeconomic disparities and shapes the city’s socio-spatial dynamics. This segregation, driven by land prices and private ownership, has pushed disadvantaged groups to the periphery and limited their access to desirable areas reserved for wealthier segments of society. Quebrada Macul Park, situated within this segregated urban landscape, serves as an emblematic case that challenges and expands the classical definition of urban segregation. It exemplifies the complex negotiations over space utilization among social groups, defined by socioeconomic, generational, and interest-based differences. This study employs micro-segregation studies in a broad sense, both as a conceptual framework and as a methodological tool to analyze these dynamics. Through qualitative methodologies, including six in-depth interviews with diverse stakeholders (social and ecological activists, longtime residents, and park employees) and five participant observations, the research investigates the varied uses and meanings attributed to the park. The findings reveal that the park’s evolution from a space frequented by low-income dwellers to a diverse metropolitan park has sparked debates over its public versus private character, mirroring the power struggles among distinct social factions. The park serves as a profound identity marker for its historical inhabitants, who initially fought for the right to use it and today experience nostalgia due to its widespread popularity. Meanwhile, the struggle to establish the park as a public space challenges the city’s segregation dynamics and might promote social cohesion within urban natural environments.

Ad Hoc Tools for Urban Renewal: The San Borja Remodeling in Santiago, Chile, 1967-1976

Conceived, developed, and built in Santiago de Chile between 1967 and 1976, the San Borja Remodeling project was the flagship of the first years of the Urban Improvement Corporation (Corporación de Mejoramiento Urbano, CORMU), a State agency created in 1966 that would become an active actor in the renovation of Chilean cities. Despite the project's significance, not only in terms of its scale and location in the centre of the Chilean capital city but also for having pushed the capacities of both the State and private companies, previous research has not addressed the full variety of tools brought together to carry out a project of this magnitude and ambition. This article describes the complexities of the San Borja project in its development. It argues that the ambition to renovate a central area in the capital city led its designers to shape and rely on ad hoc design and legal tools to make it possible. Rather than imposing a totalizing design for the city, there was a pragmatic approach aimed at developing an incremental urban renewal plan led by the State, far from both centralized planning and neoliberal urbanism.

Children's agencies navigating sexism and LGBTI+ phobia in Santiago de Chile's primary school

AbstractThrough their talk, actions and interactions, children actively shape and develop notions of gender and sexuality. This research delves into the realm of children's agency to explore the ways children act and react to instances of sexism and LGBTI+ phobia. Within the context of a Gender Equity Education Program in a Chilean primary school, this study employs participatory‐action research, integrating participatory methods and participant observation, acknowledging the significance of children's agencies in knowledge construction. Analytically, a feminist post‐structuralist lens is applied to examine children's experiences, unveiling distinct categories of agencies, namely ‘reproducers’ and ‘challengers’ of the dominant discourse.

A Geospatial Model of Periurbanization—The Case of Three Intermediate-Sized and Subregional Cities in Chile

Throughout the 20th century and in the first decades of the 21st century, the geospatial dynamic exhibiting the highest rate of change globally corresponds to urban expansion surrounding metropolitan areas and large cities. Around intermediate-sized cities, there have also been rapid changes in their geographical space, but study in these areas has had less academic attention and development. Considering this context, this article intends to analyze the dynamics in the periurbanization of communes with intermediate-sized cities. In this study, three geographical criteria were defined for the definition of the study area and seven geospatial indicators of sociodemographic, socioeconomic and land occupation categories, with the purpose of determining the composition of the periurbanization process. Finally, the discussion presents a perspective on the dynamics of periurbanization, the interpretation of future projections identifying three geospatial phenomena and a proposal for a geospatial chorematic model with the composition of periurbanization, based on three subregional intermediate-sized cities in the Metropolitan Region of Santiago de Chile. This research contributes new reflections to the debate around spatial planning and periurban research in Latin America and the Global South.

Inequities in urban tree care based on socioeconomic status

Urban trees are key elements for livable cities because they provide ecological, social, and economic benefits. Due to their importance, tree care should assure their welfare and ecosystem service provision. Among tree care strategies, pruning is highly controversial because it can be performed poorly, risking tree and human welfare. For the first time, we investigate whether the “luxury effect”, that describes a positive effect of human wealth on plant diversity, extends to urban tree care. In the Latin American city of Santiago de Chile, we sampled trees in 120 sites located in residential areas of different socioeconomic status. At each site, a trained forester evaluated each tree recording the occurrence and quality of pruning. We used a Generalized Linear Mixed Model with logistic distribution to estimate the probability of good pruning according to socioeconomic status. We found most trees (82 % of 510 trees) were pruned and most of them had poor corrective pruning applied. Good pruning increased with socioeconomic status of neighborhoods: 15 %, 31 %, and 54 % of pruned trees in low, medium, and high socioeconomic status, respectively. There was a significantly higher probability of finding well pruned trees in residential areas of high socioeconomic stratum than in lower strata. Our study reveals that trees in poorer zones are massively affected by the extended application of poor pruning that, in turn, risk ecosystem service provision for vulnerable people. Urgent strategies need to be implemented to prevent further tree damage in Santiago de Chile, especially in lower socioeconomic zones. Due to the widespread application of poor pruning on residential trees in our city and the paucity of local and global research on the relationship between socioeconomics and urban tree care practices, we make a call to investigate these patterns, especially in cities that exhibit social, economic, and environmental segregation.

Serious games and transport justice: Examining redistributive issues through classification and dictator games

IntroductionSerious games can provide an important contribution to grasp how people perceive certain social issues related to transport and what factors are more relevant for them. The paper examines the use of serious games as tools to understand how citizens perceive possible inequalities related to urban mobility and what factors they consider relevant for (re)distributing resources among different social groups experiencing such inequalities. MethodsTwo serious games, a classification game and a dictator game, are applied in Santiago de Chile, a city characterised by significant inequalities that affect also transport. The games are tested in seven focus groups involving 33 participants, arranged according to their socioeconomic conditions. In the games, participants have to rank six fictional characters and distribute among them resources to finance their mobility needs. ResultsParticipants tend to privilege socioeconomic variables such as income, rather than considering other significant individual features or the actual mobility needs of different characters. The resources are distributed focusing on the characters perceived as disadvantaged. Such perception of mobility-related inequalities does not show significant differences between participants from different social backgrounds. ConclusionsSerious games can be helpful to anticipate how the general public may perceive controversial policy measures and to plan measures to avoid discontent, providing relevant elements to enhance the social acceptability of certain transport policy decisions. Their relevance is significant in the face of pressing societal issues, also in relation to health, although their implementation can be quite time- and money-consuming.

Polycystic Ovary Syndrome and Mental Health: Influence of Hyperandrogenism During Brain Plasticity Periods on Emotional Distress and Social Cognition [ID 2683671

INTRODUCTION: Polycystic ovary syndrome (PCOS) is the most prevalent cause of endocrine disorders in teenagers. Hyperandrogenism affects brain maturation, especially in high plasticity periods (intrauterine and adolescence), potentially modulating the social-emotional status of affected adolescents (aPCOS). This study characterizes the consequences of hyperandrogenism in social-emotional status and social cognition on aPCOS. METHODS: This was an analytical cross-sectional study that included aPCOS between 12 and 25 years. Each patient underwent a clinical evaluation and measurements of the following: intrauterine androgen exposure markers (2D:4D, AGD), hormonal parameters, psychological questionnaires (PANAS, SDQ, EQ/SQ, RET, CAM), and Eye-Tracking (Tobii). This study was approved by Universidad de Chile's ethics commitee. RESULTS: Ninety participants were included: 43 cases and 47 controls. aPCOS presented more intrauterine exposure to androgens ([15/18] AGD: 9.7 versus 7.8; P=.014) and hyperandrogenemia ([15/18] FAI: 7.5 versus 4.1; P=.004). They exhibited a predominance of negative affects ([43/47] PANAS: 8.0 versus 2.0; P=.049), more socio-emotional problems ([43/47] SDQ: 2.5 versus 1.5; P=.047), less self-reported empathy ((43/47) EQ: 19.0 versus 25.1; P=.001), and differences in gaze patterns, such as longer time to first fixation in areas of interest (s) ([7/3] AOI(s): 0.35 versus 0.28; P=.037), which was associated with a worse score in emotional recognition (CAM; aR2=−0,920; f=19,48; Pr>|t|=|t|=0.049). CONCLUSION: aPCOS presented with predominance of negative affects, more social-emotional difficulties, and lower score on emotional recognition, associated with exposure to hyperandrogenism during the most critical neuroplasticity periods. These findings suggest that mental health should be evaluated on every PCOS patient, especially adolescents.

Bodily Practices and Meanings Articulated in the Physical Exercise of Older Adults in Santiago de Chile Post-COVID-19.

This article presents the results of almost nine months of ethnographic research on the relationship between physical exercise and health in older people in the post-COVID-19 context. Via exploratory-descriptive qualitative research and the use of a convenient sample, I shed light on this relationship using the stories and life experiences of 40 older people (10 men and 30 women, including two women instructors for senior classes) who exercise regularly. The meanings they attributed to physical exercise during COVID-19 and after it are explained, emphasising first that there is no health in a context of not feeling safe; once there is a feeling of security, the most relevant meanings can be exposed in three directions. First, exercise produces a sense of identity linked to "being an athlete" and "belonging to a group". Second, exercising is valued as participating in something meaningful (the meanings range from self-realisation, independence, and autonomy to feelings of happiness). Finally, and linked to the sense of identity, those who train alone show more commitment and total hours spent in physical exercise and physical activity than those who train in groups. Even though older people are not a homogeneous group, they generally faced the pandemic as an ageist situation that affected their lives and how they saw sports and health. This article describes the strategies they used during COVID-19 related to exercise and well-being and those used once the pandemic restrictions were no longer present. The qualitative aspects that physical exercise brings to this population are highlighted. The research results give voice to older people, showing their heterogeneity and the meanings and practices that unite them. These inputs are rich material for studies on physical activity, older people, and well-being.

Socio-spatial analysis of migrant school students according to Bourdieu's capitals in Santiago de Chile (2017–2020)

Chile has experienced a substantial immigration boom in the last 10 years. The urban areas of this nation present high levels of residential segregation, represented in its main city, Santiago. This article presents results of an exploratory analysis of the relationship between residential segregation, immigration rate by educational institutions and changes in school performance. Based on the generation of clusters characterized by cultural, social, economic and symbolic capital, an analysis of the changes in school performance in those schools that received the greatest number of migrants is generated.

Violent demonstrations in marginal territories and their place in politics: A case study in Lo Hermida, Santiago de Chile

This article aims to investigate violent demonstrations in marginal territories of Santiago de Chile and their political dimension, studying the territorial deployment of structural violence, transgressive protest actions, and subjectivation processes. These three dimensions tell us about the political, social, and territorial intertwining of violent demonstrations, based on Jacques Rancière's framework. We conducted a case study in Lo Hermida, a highly politicized self-constructed neighborhood born in the 1970s that is currently surrounded by transportation infrastructure and upscale urban developments. Using secondary sources, semi-structured interviews, and photo-elicitation with 14 residents of Lo Hermida, we show the way in which structural violence is experienced across the territory, how transgressive protest actions are carried out in violent demonstrations throughout it, and how processes of political subjectivation unfold from this. The conclusions emphasize the incorporation of the political-subjective dimension in the understanding of violence in marginal territories, highlighting its emergent characteristics in space.

Are Professional Skills Learnable? Beliefs and Expectations Among Computing Graduates

Integrating graduate education with professional skills development is still a challenge. People's beliefs about learning impact their learning processes. Therefore, we need to understand the mindset of graduates to determine best practices for promoting professional skills development. In this study, we explore the perspective of computing graduates within an Engineering educational program. This study aims to answer the following research questions: Which skills do computing graduates perceive they need in the workplace, and how do they position themselves regarding these skills? What learning beliefs do computing graduates hold regarding the skills required in the workplace? The research team conducted semistructured interviews with computing graduates within an Engineering program to analyze their experiences. The interviews were analyzed using grounded theory. As a result, the participants viewed professional and technical skills as independent, with professional skills perceived as more relevant to work success. The participants considered themselves to possess these skills. Our findings identify four learning beliefs within a fixed and growth mindset: (1) An essential personal characteristic that context may influence; (2) a learning outcome determined by early experiences; (3) a learning process associated with informal learning experiences; and (4) a learning process associated with formal learning experiences. We acknowledge the differences in perception between alums and the industry regarding possessing essential professional skills. We also highlight the need to position these skills as learnable during lectures contributing to Computing and Engineering Education.

Archaeology of Repression in Latin America

This study was undertaken during the October Revolt, a period of demonstrations, discontent with the government and confrontations between protesters and the police (Carabineros de Chile) and armed forces. We used archaeological tools to shed light on clashes between the police forces demonstrators, and on the ways this conflict took shape. Our analysis refers to locations that we call Sites of Demonstration and Protest (SDP) and Nuclei of Repression and Self-Defense (NRS).

Chilean Market Protein Shakes Composition.

Understanding the nutritional content of protein supplements is crucial for optimal nutritional planning among athletes and other people. Distribution of macronutrients and aminograms in the main products available in the national Chilean market remains unknown. A descriptive cross-sectional study was conducted to identify the main protein supplements available in the Chilean market. Information on macronutrients and aminograms from the nutritional labels of each product was extracted. The analysis considered the content per portion and per 100 g. Cluster analysis models and graphical representations were explored. Eighty protein shakes were assessed in the Santiago de Chile market. The median protein dosage was 32 g (range from 25 to 52), and the median energy value stood at 390 kcal (range from 312 to 514). The median protein content per 100 g of product was found to be 75 g (range from 42.5 to 97.2). The combined median concentration of amino acids was 4749.75 mg. Among these, the essential amino acid L-Tryptophan exhibited the lowest concentration at 1591.50 mg, while the conditional amino acid L-Glutamine had the highest median concentration at 17,336 mg. There was a significant prevalence of animal-derived products, placing specific emphasis on protein supplements that feature elevated levels of the amino acids L-Glutamine and L-Leucine.

Ecosystem Orchestration: Unpacking the Leadership Capabilities of Anchor Organizations in Nascent Entrepreneurial Ecosystems

Although prior research emphasizes the essential role of anchor organizations’ leadership in entrepreneurial ecosystem development in the early stages, their strategic functions are undertheorized. This study conducted a single case study with the entrepreneurial ecosystem of Santiago de Chile as a revelatory case by examining how anchor organizations catalyze the early evolution of the entrepreneurial ecosystem from the perspective of the orchestration theory. We developed a framework of ecosystem orchestration to demonstrate how anchor organizations adapt their strategic functions in managing and building various networks and resources to dynamic environments in entrepreneurial ecosystems.
