Item type:Publication, The commitment to infrastructure: Public investment and the reproduction of water scarcity in contexts of large mining in Peru and Colombia(Universidad Catolica del Norte, 2022-01-01)Public and private policies typically consider the construction of infrastructure the most appropriate response to the problems of water scarcity and water disputes. However, infrastructure in itself not always is the solution. In this context we have the following questions: What are the logics behind the construction and implementation of water infrastructure? Why water infrastructures are not alone a solution to water stress and scarcity? How does infrastructure construction reduce or deepen inequalities in access to water? This article answers these questions by arguing that water infrastructures respond to technical-political projects of territorial control and mining expansion located in areas of mining influence, rather than aiming to solve water access and supply problems. In doing so, they ended up deepening inequalities in local water access. This article compares infrastructures constructed in the context of large-scale mining projects in Espinar, Peru and La Guajira, Colombia. The information presented was collected following qualitative methods (semi-structured interviews and situated ethnographies). Likewise, the article systematizes secondary quantitative and qualitative data provided by government institutions related to water and mining, and the Environmental Impact Studies and web publications regarding the Tintaya-Antapaccay and Cerrejón mining projects. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, How the perception of corruption shapes the willingness to bribe: Evidence from an online experiment(Oxford University Press, 2024-01-01)Does the perception of corruption shape the willingness to bribe? This study evaluates the socio-psychological determinants of corruption by measuring how different types of messages influence the probability of engaging in corruption for access to public health, social programs, and official documents. This research uses the social norms approach to explore the link among messaging, perception, and behavior. An online experiment was conducted in Peru for two weeks between October and November 2021, using social media (Facebook) to recruit participants (n = 2584). The participants were divided into two treatment groups and one control group. Those in the treatment groups received informational displays on (i) the perception of corruption as widespread in the public sector (descriptive norm) or (ii) corruption as morally wrong (injunctive norm). The control group did not receive a message. Exposure to messages on corruption increased the overall probability of engaging in corruption. Unexpectedly, those in the injunctive norm group increased their willingness to bribe. Furthermore, this study also found significant differences in bribing behavior based on the different types of public service, gender, and age. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Enhancing ultrasonic attenuation images through multi-frequency coupling with total nuclear variation(Acoustical Society of America, 2024-10-01)Quantitative ultrasound is a non-invasive image modality that numerically characterizes tissues for medical diagnosis using acoustical parameters, such as the attenuation coefficient slope. A previous study introduced the total variation spectral log difference (TVSLD) method, which denoises spectral log ratios on a single-channel basis without inter-channel coupling. Therefore, this work proposes a multi-frequency joint framework by coupling information across frequency channels exploiting structural similarities among the spectral ratios to increase the quality of the attenuation images. A modification based on the total nuclear variation (TNV) was considered. Metrics were compared to the TVSLD method with simulated and experimental phantoms and two samples of fibroadenoma in vivo breast tissue. The TNV demonstrated superior performance, yielding enhanced attenuation coefficient slope maps with fewer artifacts at boundaries and a stable error. In terms of the contrast-to-noise ratio enhancement, the TNV approach obtained an average percentage improvement of 34% in simulation, 38% in the experimental phantom, and 89% in two in vivo breast tissue samples compared to TVSLD, showing potential to enhance visual clarity and depiction of attenuation images.1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A Kaleidoscopic Reflection on Territory and Property Histories, Cultures and Inequalities(University of Torino, 2023-12-31)The multiple meanings of Indigenous territory and property are explored here by means of a multidisciplinary lens. An ethnological journey through different geographies and times is undertaken to explain some property formation processes and illuminate how they unfold in the Andean region and, particularly, in Peru. Based on four core notions of anthropology—time, space, culture and power—Indigenous territory and property are described showing how land commodification has imposed detrimental effects on indigenous peoples. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Examining the connection between position-based power and social status across 70 cultures(Wiley, 2025-04-01)Even in the most egalitarian societies, hierarchies of power and status shape social life. However, power and received status are not synonymous-individuals in positions of power may or may not be accorded the respect corresponding to their role. Using a cooperatively collected dataset from 18,096 participants across 70 cultures, we investigate, through a survey-based correlational design, when perceived position-based power (operationalized as influence and control) of various powerholders is associated with their elevated social status (operationalized as perceived respect and instrumental social value). We document that the positive link between power and status characterizes most cultural regions, except for WEIRD (Western, Educated, Industrialized, Rich, Democratic) and Post-Soviet regions. The strength of this association depends on individual and cultural factors. First, the perceived other-orientation of powerholders amplifies the positive link between perceived power and status. The perceived self-orientation of powerholders weakens this relationship. Second, among cultures characterized by low Self-Expression versus Harmony (e.g., South Korea, Taiwan), high Embeddedness (e.g., Senegal), and high Cultural Tightness (e.g., Malaysia), the association between power and status tends to be particularly strong. The results underline the importance of both individual perceptions and societal values in how position-based power relates to social status.2
