Published: April 2023

Os direitos consagrados na CF/88, foram criados com o objetivo de resguardar o cidadão de excessos do Estado, impedindo abusos decorrentes de agentes públicos. O controle da administração pública é regulamentado através de diversos atos normativos, que trazem regras, modalidades e instrumentos para a organização desse controle. Este trabalho busca analisar como é feito o controle externo da atividade policial pelo Ministério Público (MP) brasileiro, bem como analisar como tal atividade de fiscalização pode influenciar na ação policial interna e externa. Esta é uma pesquisa exploratória, aplicada e bibliográfica. Como resultados identificamos a origem das organizações policiais no Brasil; a execução das políticas de segurança pública e suas consequências para as minorias; A estrutura normativa do Ministério Público Estadual para atuação no controle externo da atividade policial. Como implicações práticas sugerimos ações que podem reduzir a violência policial como: Investir na formação continuada da força policial no que tange aos direitos humanos, ao treinamento e aplicação de armas não letais; Investimento em inteligência policial para melhorar o planejamento das operações; Investimento em câmeras corporais e nas viaturas, pois acreditamos que inibirá as ações violentas, e será uma prova de defesa para os policiais que atuam dentro da lei; Definição de normas e procedimentos operacionais sobre a atuação em comunidades conflagradas que possam ser auditados pelo MPE e acompanhado pelos organismos sociais; Criação de um setor específico no MPE para o controle mais efetivo sobre os organismos policiais. E pelo Fortalecimento do controle interno das organizações policiais.

Kinematic bending of piles in made ground
Authors: Di Laora Raffaele
Published: April 2023

This work explores earthquake-induced kinematic bending in the so far unresolved case of a pile embedded in a two-layer soil with a thin surface layer. The problem is treated analytically by means of a generalised Winkler model, which in addition considers the effect of boundary conditions at the pile head over earlier contributions on the subject. Novel analytical closed-form expressions of the kinematic bending moment at the pile head and at the interface between the two soil layers are provided for both fixed- and free-head piles. The analytical solutions are validated through a rigorous finite-element model, which proves a remarkable accuracy in the static regime. While for interface bending the past literature indications for the dynamic coefficient make the proposed formula accurate for both shallow and deep interface, a novel dynamic interaction factor, describing dynamic effects for pile-head bending, is introduced. A numerical example provides guidance on application of the formulae in real design scenarios.
Above and below verbal roots: A case study of English adverbs of results
Authors: Jung Hyun Kyoung , Choi Jaehoon
Published: April 2023

This study investigates English resultative adverbs focusing on their syntactic peculiarities. Based on the observation that resultative adverbs can appear in certain activity verb phrases, we argue for an elaborate verbal structure. In particular, we propose that two distinct syntactic heads need to be postulated for resultative adverbial modification (Res(ult)) and for encoding the aspectual information of the verb (v). The proposal correctly predicts the distributional contrasts between resultative and manner adverbs, the patterns of adverbs ambivalent in denoting manner and result meanings, and the possibilities of modification of verb and adjective derivatives. The analysis of resultative adverbs advanced in this study is shown to newly account for measure adverbs. In doing so, we demonstrate that certain roots can head-adjoin either to Res or v with the corollary that the resulting verb can either denote a result or manner. Finally, an implication of this study is discussed regarding the relationship between result roots and the Res head.

Pancreatic β cell-specific deletion of Helicase-like transcription factor (Hltf) activates the Hmgb1-Rage axis and granzyme A-mediated killing of pancreatic β cells resulting in neonatal lethality v1
Authors: Kaur Gurvinder
Published: April 2023

Insulin-producing pancreatic β cells maintain glucose homeostasis and their loss of function causes diabetes. Epigenetic mechanisms that do not alter the DNA sequence are integral to β cell function. Promoter hypermethylation of the helicase like-transcription factor (HLTF) gene—a component of the cellular DNA damage response that contributes to genome stability—has been implicated in age-associated changes in β cell function. To study helicase-like transcription factor (HLTF) we generated global and β cell-specific (β) Hltf knockout (KO) immune competent (IC) and immune deficient (ID) Rag2-/IL2- mice. IC global and β Hltf KO mice were neonatal lethal whereas ID global and β Hltf KO newborn mice had normal survival. This focused our investigation on the effects of Rag2 interruption with common gamma chain interruption on β cell function/survival. Three-way transcriptomic (RNAseq) analyses of whole pancreata from IC and ID newborn β Hltf KO and wild type (Hltf +/+) controls combined with spatially resolved transcriptomic analysis of formalin fixed paraffin embedded tissue, immunohistochemistry and laser scanning confocal microscopy showed DNA damage caused by β Hltf KO in IC mice upregulated the Hmgb1-Rage axis and a gene signature for innate immune cells. Perforin-delivered granzyme A activation of the DNase, Nme1, damaged nuclear single-stranded DNA (γH2AX immunostaining). This caspase-independent method of cell death was supported by transcriptional downregulation of the Serpinc1 gene that encodes a serine protease inhibitor of GzmA. Increased transcriptional availability of the complement receptors C3ar1 and C5ar1 likely invited crosstalk with Hmgb1 to amplify inflammation. This study explores the complex dialog between β cells and immune cells during development, and has implications for the initiation of type I diabetes in utero, when a gene deletion that compromises genome stability invokes a localized inflammatory response.

BACKGROUND: Today, cardiovascular, oncological, and neurodegenerative diseases are the main causes of death in the world, according to official World Health Organization (WHO) statistics. Antioxidants are used to treat and prevent these diseases. In order to develop optimal technology for obtaining drugs based on plant extracts with antioxidant action, it is necessary to determine the total antioxidant capacity of raspberry shoots.OBJECTIVES: The study aimed to determine the total antioxidant capacity of red raspberry shoots, study the content of biologically active substances (BAS), and the antioxidant activity of red raspberry shoot extracts obtained during subsequent exhaustive extraction.METHODS: The number of phenolic compounds, catechins, flavonoids, and hydroxycinnamic acids was determined by a spectrophotometric analysis method, whereas organic acids were determined by the alkalimetric method in red raspberry shoot extracts; the antioxidant activity of obtained extracts was evaluated by potentiometric method. RESULTS:  The total antioxidant capacity of red raspberry shoots was 164.12 mmol-equiv./m dry weight, the sum of the total content of phenolic compounds was 24.40 mg gallic acid (GA)/mL, catechins – 21.36 mg epigallocatechin-3-O-gallate (EGCG)/mL, flavonoids – 0.77 mg rutin (R)/mL, hydroxycinnamic acids derivatives – 2.56 mg chlorogenic acid (ChA)/mL and organic acids – 1.88 mg citric acid (CA)/mL in red raspberry shoot extracts obtained during subsequent exhaustive extraction. The analysis showed that there is a very high positive correlation between antioxidant activity and total phenolic compounds, catechin, flavonoid, hydroxycinnamic acids derivatives, and organic acids content in red raspberry shoot extracts. CONCLUSIONS: Total red raspberry shoots' antioxidant capacity has been determined. The study results can be used to develop optimal technology for obtaining drugs based on the extract of red raspberry shoots, which has an antioxidant effect.
Gap Analysis Between the Level of Heat Wave Adaptation Policy and Heat Wave Effects in South Korean Municipalities
Authors: Kim Tae Ho , Park Chang Sug , Lee Sang-hyeok , Kang Jung Eun
Published: April 2023

This study aims to analyze the gap between the level of heat wave adaptation policies and heat wave effects in South Korean municipalities. First, the types of industries in municipalities were classified using factor analysis and cluster analysis. Second, the level of heat wave adaptation policy in the municipalities was assessed using a fuzzy analytic hierarchy process analysis. Third, the gap between the level of heat wave adaptation policy and the heat wave effect was analyzed. The results show that the heat wave adaptation policies were established in accordance with the heat wave effects to at least some degree. However, closer to the long-term future (2095), the policies have not sufficiently matched the level of heat wave effects. The proportion of municipalities with insufficient levels of heat wave adaptation policies against the heat wave effects was higher among urban-type municipalities. The analysis results suggest two policy implications. First, the heat wave adaptation policies of municipalities should be established through continuous feedback on the predictions of future heat wave effects. Second, urban-type municipalities should strengthen their planning authority and competence by securing a professional workforce and budgets for the establishment of heat wave adaptation policies.

Entreguerras y la tradición del poema largo autobiográfico
Authors: Luján Atienza Ángel Luis
Published: April 2023

Este trabajo pretende dar cuenta de la tradición en la que se inserta el poema Entreguerras, de José Manuel Caballero Bonald (2012). Para ello se explora en primer lugar la relación entre poesía y autobiografía con el fin de demostrar la capacidad de referencia que tiene la lírica. A continuación se comprueba cómo este modo de referir, oblicuo y que construye la realidad al nombrarla, puede traspasarse al poema largo dando origen a una línea de autobiografías en verso que comparten ciertos rasgos y cuyo principal característica común es que constituyen en sí mismas un proceso de revelación o autoconocimiento más que el testimonio de una realidad vivida.

Overdiagnosis of schizophrenia as a cognitive distortion of the process of knowledge of clinical reality
Authors: Mendelevich Vladimir D.
Published: April 2023

The article is devoted to the analysis of the causes of overdiagnosis and misdiagnosis of schizophrenia from the standpoint of cognitive distortions in the process of cognition of clinical reality. Using the diagnosis of sluggish schizophrenia as an example, it is concluded that overdiagnosis is based on the false consensus effect, which in psychiatry reflects the diagnosticians solidarity with the position of the scientific school to which he belongs, and with the inability to resist the pressure of authorities. A clinical example of an erroneous diagnosis is given. In conclusion, it is stated that the overdiagnosis of schizophrenia and the unjustified prescription of antipsychotic therapy to patients leads to the discrediting of psychiatry and the stigmatization of the mentally ill. This trend should be reconsidered and the diagnosis of schizophrenia should be made solely on the basis of obvious, and not indirect, clinical phenomena.

Published: April 2023

La nueva jurisprudencia del Tribunal Constitucional sobre la delegación de voto en las Asambleas legislativas autonómicas surgida a propósito de su empleo en el Parlamento de Cataluña supone la necesidad de revisar su regulación en todas aquellas en las que se emplea esta técnica. Las sentencias desarrollan el principio de personalidad del voto y lo relacionan con el ius in officium, así como se pronuncian acerca de la naturaleza del sufragio de los representantes públicos extendiendo los requisitos del art. 79.3 de la Constitución más allá de diputados y senadores. Este artículo presenta una sistematización de las resoluciones, explica su contexto y contenido, amén de abordar algunos de sus puntos débiles en consonancia con el voto particular concurrente desde una perspectiva favorable a considerar el principio de lealtad al sistema y el protagonismo del miembro individual de las Cámaras como bases inexcusables para cualquier interpretación flexible de las normas básicas del derecho parlamentario.
Comparison of TRAP (triceps reflecting anconeus pedicle approach) v/s olecranon osteotomy approach for treatment of intercondylar fracture humerus
Authors: Goyal Roshan Lal , Sharma D K , Banodha Laxman
Published: April 2023

Distal humerus fractures constitute 2 to 7% of all the elbow fractures. Young males are most commonly affected due to high energy trauma and secondly seen in elderly women due to osteoporosis. Due to complex anatomy and neurovascular network nearby, the treatment is very difficult. Anatomical reconstruction is the key for successful functional outcome. We compared the TRAP and olecranon osteotomy approach for the management of intraarticular fractures of the humerus in terms of functional, clinical and radiological outcome.

The study was conducted in the Department of Orthopaedics & Traumatology, MGM Medical College and MY Hospital, Indore from August 2019 to August 2021 on 30 patients with intra-articular fractures of humerus. 15 patients were treated with olecranon osteotomy and 15 patients were treated with TRAP approach, on patients fulfilling all the inclusion, but none of the exclusion criteria. The functional outcome was measured using Mayo Elbow Performance Score (MEPS) and radiographs were used for evaluating the bone union time.

There was a male predominance. Assault, fall and road traffic accidents were the modes of injury. 13-B2, 13-C1 and 13-C3 were commonly seen fracture types. Mean MEPS was significantly better in TRAP (P<0.05) and full triceps strength was achieved in 86.7% patients by 3 months in TRAP and by 6 months in olecranon osteotomy group. The mean blood loss and duration of surgery was significantly longer in olecranon group (P<0.05). The bone union time and hospital stay were comparable between the groups (P>0.05). 73.3% patients of TRAP and 64.3% patients of olecranon osteotomy group achieved excellent outcome by 6 months.

TRAP approach is comparatively better than osteotomy approach. Both the methods provide a stable fracture fixation, but complications are more in osteotomy in comparison to TRAP and we found TRAP to be functionally better.

Comparison of orthopedic fractures operated during the COVID-19 pandemic with the pre-pandemic period
Authors: Boz Mehmet , Güzel İsmail
Published: April 2023

The duration of staying at home increased during the coronavirus pandemic due to the people’s instincts to protect themselves and lock down. The aim of this study is to compare the changes in orthopedic trauma patients operated in the same term of the coronavirus disease 2019 (Covid-19) pandemic and pre-pandemic periods.

This retrospective study was conducted with data obtained from Malatya Training and Research Hospital and compared the Covid-19 pandemic and pre-pandemic period. Orthopedic trauma patients who were operated in the Orthopedics and Traumatology clinic between 24 March-1 July, 2020 and 24 March-1 July, 2019 were included in the study. The patients’ demographic characteristics (age and sex) and trauma-related information (type and site of the fracture, osteoporotic fracture, injury mechanism and treatment modality) were compared between two groups.

There were statistically significant differences between the groups in terms of the rates of osteoporotic fractures. We are in the opinion that arrangements for individuals with a high risk of osteoporotic fracture should be made where they can practice physical activities such as walking and exercising at certain times, when there is a lock down during the pandemic. Additionally, detailed studies on traumas that may occur due to increasing stress during such pandemics should be conducted.

A total of 439 patients were included in the study. The traffic accidents were significantly lower in the pandemic group than the pre-pandemic group, simple falls were significantly higher in the pandemic group than the pre-pandemic group (P<0.05). Additionally, fractures induced by hitting a hard surface and gunshot wounds significantly increased in the pandemic group compared to the pre-pandemic group (P<0.05).
Low grade central osteosarcoma transforming to high grade sarcoma – Clinical implications and brief review of literature !
Authors: Yadav Arun Kumar , Tewari Shatakshee , Singh Anshul , Misra Vatsala
Published: April 2023

Low grade central osteosarcoma (LGCO) are rare intramedullary bone tumours of adolescents and young adults with an excellent prognosis. They have a predilection for long bones around the knee joint, but cases have been reported in long bones of arm, tarsals and flat bones of jaw, ribs and scapula as well. Their transformation to high grade sarcomas are rarely seen. We report a case of an 16 years female who presented with complaints of progressive pain in the lower thigh 2 years back. Her x-ray suggested a simple bone cyst in distal femur, following which wide excision of the cyst was done. Histopathology however showed features of LGCO. The patient was apparently alright in the follow up period until 9 months ago when the patient had a recurrence of swelling accompanied with pain at the same site leading to difficulty in walking. This time her X-ray showed neoplastic changes after which the tumor was excised. On microscopy, areas of high grade sarcoma with soft tissue extension were seen predominantly. This case is being reported to make the clinicians and diagnosticians aware of the rare but highly significant implication of transformation of LGCO to high grade tumors as it carries a guarded prognosis and calls for a different treatment strategy compared to conventional LGCO.

Low grade central osteosarcoma (LGCO) are rare intramedullary bone tumors seen in adolescents and young adults. It bears an excellent prognosis. We present a case report on LGCO showing transformation to a high grade sarcoma that radically changes its prognosis as well as calls for a different treatment strategy.

Published: April 2023

A tecnologia digital disponibiliza à televisão facilidades que o sistema analógico não permite. Tais funcionalidades permitem que os usuários do sistema digital possam acessar conteúdos de páginas web, informação hipermídia, imagem e áudio digital. Contudo, o ponto crucial da mudança de formato da TV é, não apenas qualidade excelente dos sinais de áudio e vídeo, mas também a possibilidade da execução de aplicações, assim como acontece nos computadores, possibilitando aquilo que há muito as indústrias de comunicação perseguem: interatividade real. Esta interatividade promove o desenvolvimento e a integração de novos serviços para televisão, como: jogos, EPG, sistemas de acesso bancário, comércio eletrônico, dentre outros, proporcionando ao telespectador interagir com o sistema e com demais usuários tornando-se um agente ativo no ambiente televisivo. O objetivo do presente trabalho é descrever as possibilidades da Televisão Digital Interativa (TVDI), detalhando todo o processo de transmissão e recepção das informações através dos mecanismos de codificação, multiplexação e modulação de sinal. O trabalho também apresenta os principais padrões de TV digital e middlewares, dando maior enfoque ao padrão o Internacional Standard for Digital Television Terrestrial (ISDTV-T) e ao middleware Ginga, ambos especificados durante o projeto Sistema Brasileiro de Televisão Digital (SBTVD). Para o desenvolvimento de aplicações interativas, dentro deste contexto é elucidado qual o suporte necessário que a API JavaTV disponibiliza aos desenvolvedores na construção dos softwares a serem executados nos Set-Top Box.

Authors: Khemiri Souhir , Feki Jihene , Toumi Nabil , Khanfir Afef
Published: April 2023

The association between multiple myeloma and solid cancers is rarely described in the literature. Some authors report that multiple myeloma increases the risk of developing some cancers such as breast cancer. We report three cases of multiple myeloma and breast cancer metachronous in order to study the etiopathogenesis of this association. Such a big spectrum of these studies should be done to understand whether there is a relation between causes of these two diseases or the risk factors behind this rare association. Our objective is to be able to define patients with high and low risk of developing secondary cancer in order to adapt the therapies and propose possibly screening for colon and breast cancers every two years for patients with high-risk multiple myeloma.

Materials and Methods: This cross-sectional study was accomplished on Shahid Beheshti University of Medical Sciences (Tehran, Iran) employees during January and September 2022. Eligible participants were selected based on the simple ran- dom method and interviewed about side effects after injecting COVID-19 vaccine.
Results: The mean age of 656 participants was 38.03 ± 9.53 years, and 453 (69.1%) were female. The prevalence of post-vac- cination side effects was higher after receiving the first dose (53.2%) than the second (35.9%) and third (49.4%) doses. Across all three vaccine doses, the overall proportion of side effects was higher following AstraZeneca than the others. The most common side effect after the first dose of the vaccine was myalgia (41.9%), followed by fever (36.6%), chills (31.6%), local reactions (27.0%), headache (25.5%), and sweating (21.6%). People experienced mainly myalgia (23.3%) and fever (20.3%) after injecting the second dose of the vaccine. Additionally, the participants had myalgia (37.2%), fever (30.8%), chills (29.2%), local reactions (26.0%), and headache (24.4%) after the third dose of the vaccine.
Conclusion: AstraZeneca had a higher proportion of post-vaccination adverse effects than Sputnik V, Pastocovac, and Sin- opharm. The most common side effects were flu-like syndrome and local reactions at the injection site. Furthermore, people rarely experienced life-threatening side effects. Thus, the available COVID-19 vaccines in Iran are safe.

Published: April 2023

Background and Objectives: Heavy metals pollution is one of the most important concerns in the world. Selenium is one of the most important elements for the life, but if the absorption of this element in cells increases, it acts as a toxic element.
Materials and Methods: In this study, bacterial isolates were screened and isolated from selenium-contaminated soil and water. Twenty -five out of 42 isolates were able to reduce Selenite. Also, the response surface method (RSM) was used to evaluate and optimize the biological reduction of selenite by Selena 3. Factors of bacterial inoculation percentage, time, and amount of selenium oxyanion salt concentration were studied at five levels of -α, -1, 0, +1, and +α.
Results: Bacillus sp. Selena 3 was able to reduce 80 mM sodium selenite in less than 4 hours compared to other bacteri- al isolates. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of sodium selenite Bacillus sp. Selena 3 was reported as 160 and 320 mM, respectively. The results showed that with increasing duration, the percentage of selenite reduction by bacteria increases and the percentage of bacterial inoculation does not have much effect on its reduction.
Conclusion: Due to the ability of Bacillus sp. Selena 3 for rapid reduction in significant concentration of selenium oxyanion (SeO 2-), this bacterium can be used as an efficient candidate in removing selenite from the environment.

Published: April 2023

Introduction: The destructive effects of anticancer drugs such as cisplatin are well known. In recent years, it has been found that medicinal plants have a fundamental role in protecting the damage caused by drug. The purpose of this study was to investigate the effects of vaccinium arctostaphylus plant one of the prevalent materials in traditional medicine in improving the disorders caused by cisplatin in testicular tissue.
Methods: In this research, forty rats were divided into 5 groups (G) (n=8) based on administration cisplatin and extract of vaccinium arctostaphylus. In G1 physiological serum was injected and in G2 only cisplatin was administrated. In G3, G4, and G5 Arctostaphylus vaccinium extract with a concentration of 100, 200, and 300 mg/kg along with a single dose of cisplatin were administrated. After 24 hours, the rats were sacrificed, and then testis was isolated and subjected to histopathological evaluation with t-test and one-way ANOVA test on Prism-GraphPad 9.
Results: Our results showed that in the G2 group, the number of spermatogonial cells was reduced compare with G1 (P=0.01); As well as the thickness of the germinal epithelium and the diameter of the seminiferous tubules were reduced partially. In G3 and G4 groups in comparison with G2, the germinal epithelium was improved (P=0.02). The preservation of spermatogonial cells in G3 significantly increased compare with G2 (P=0.01).  
Conclusion: According to the results, Arctostaphyllus vaccine as a native plant in defined dosages has a significant effect on improving cisplatin-induced disorders in the germinal epithelium and the number of spermatogonial cells preservation.

Introduction: This study aimed to evaluate the effectiveness of combination therapy with sertraline and compassion-enriched act on depression, stress, and anxiety in opioid abuse patients treated with methadone compared to intervention based on compass-enriched acceptance and commitment treatment alone.Methods: This study was a clinical trial with a pre-test and post-test design. Forty people were selected by voluntary sampling method; after matching, they were divided into two groups with 15 participants. The first group received compassion-enriched acceptance and commitment treatment and the second group received combination therapy with compassion-enriched acceptance and commitment treatment and sertraline for 28 days. Patients were evaluated based on the Anxiety-Stress-Depression Questionnaire (DASS-21). Data were analyzed using SPSS version 16, multivariate analysis of covariance test at the level of 0.05.
Results: The results showed that both interventional methods effectively treat depression, stress, and anxiety (p<0.01), while the combined treatment of enriched acceptance and commitment treatment with compassion plus sertraline has the most significant effect on the studied parameters (p<0.01).
Conclusion: Acceptance and commitment treatment enriched with compassion plus drug therapy effectively reduces depression, stress, and anxiety in opioid addicts under methadone maintenance treatment and can be used as an effective method in the treatment of addiction.
Reforma del Servicio Civil : avances y desafíos

En los últimos meses, todos los peruanos hemos visto en las noticias cómo los casos de contagios y muertes en nuestro país por la COVID19 se incrementaron hasta alcanzar los primeros lugares en el mundo. Frente a ello, muchos líderes de opinión y políticos han atribuido responsabilidad a las autoridades de turno debido a la baja capacidad de respuesta estatal. No obstante, la pandemia ha develado no solo problemas en la capacidad de respuesta (fruto de decisiones que se han tomado en los últimos meses), sino también problemas estructurales que no han sido abordados o cuya atención mediante políticas públicas ha sido insuficiente en las últimas décadas.

El Perú y su pasado remoto : entre las imágenes y el legado
Authors: Vega-Centeno Rafael
Published: April 2023

No cabe duda de que las imágenes y los paradigmas han sido relevantes en la construcción de las identidades humanas; sobre todo en la orientación de comportamientos y las consecuentes trayectorias de colectivos humanos. Ha sido lógico, por otro lado, que dichas imágenes estuviesen ancladas en el pasado remoto, revestidas de una simbología mítica o legendaria. En el Perú, como colectividad humana, estos procesos se han dado con algunas singularidades que se describen a continuación.
Notas sobre el futuro digital del Perú
Authors: Villanueva Mansilla Eduardo
Published: April 2023

Desde que la internet se convirtió en el principal vector de la digitalización de las sociedades y economías, el Perú ha sido un ejemplo de pasividad. Nuestra capacidad de adaptación y aprovechamiento de todo lo que puede ofrecer esta nueva forma de organizar la vida ha sido apenas un reflejo de las tendencias globales, pero pasadas por los filtros habituales: debilidad estatal, mínima capacidad de innovación, pobreza del mercado. Las pocas islas de eficiencia estatal no «contagian» al resto del Estado. Más allá de entusiasmos menores por las distantes cabinas públicas, o ciertas ideas individuales convertidas en proyectos exitosos, internet ha impactado el país como tantas otras oleadas de innovación económica e industrial: poco, tarde y, realmente, para pocos.
El espacio sagrado y el ejercicio de poder. Las doctrinas de Chayanta durante la segunda mitad del siglo XVIII
Authors: Adrián Mónica
Published: April 2023

El presente trabajo es un avance de investigación de un proyecto más amplio sobre las relaciones de poder tejidas en torno a la celebración de la fiesta religiosa en las comunidades aborígenes de la provincia colonial de Chayanta, durante la segunda mitad del siglo XVIII. La lectura de los expedientes judiciales labrados con ocasión de la visita civil-eclesiástica realizada a esta provincia en 1797 llamó nuestra atención con respecto a la estrecha relación existente entre la cosmovisión aymara del espacio sagrado y las estrategias adoptadas por los curas doctrineros para ampliar el grado de poder local frente al avance centralizador del Estado borbónico. Un ejemplo claro lo constituye la situación originada en torno a la creación del santuario de Nuestra Señora de Surumi. La comprensión que los sacerdotes poseyeron de esta cosmovisión les permitió orientar la concreción de esta medida atendiendo a la defensa de sus intereses locales como medio para neutralizar los efectos de la política de división de doctrinas llevada a cabo por el Estado.
Los vasallos se desentrañan por su Rey : Notas sobre quejas y aspiraciones de curacas en el Perú del siglo XVIII
Authors: Puente Brunke José de la
Published: April 2023

La figura del curaca sufrió en el Perú colonial grandes transformaciones: son muy notables las diferencias -tal como lo han señalado diversos autores- que pueden advertirse entre el curaca prehispánico y el colonial. Este último gozaba, en principio, de una "doble autoridad": si mantenía su prestigio entre la población indígena era porque ésta le reconocía una autoridad "andina", que era distinta a la que le otorgaba el sistema administrativo colonial, el cual vio en los curacas a los mejores "mediadores" entre españoles e indígenas. Además, la calidad de curaca no era hereditaria en los tiempos prehispánicos, de modo que éstos no eran estrictamente "señores", si por tales entendemos a quienes recibían esa denominación en la Europa feudal (Pease 1992: 128-129 y 149)
El control político de las aguas en Tarapacá : poder y conflicto. Siglos XVI-XVIII
Authors: Herrera V. Juan Alberto
Published: April 2023

Las llamadas culturas hidráulicas son aquellas sociedades que han alcanzado un manejo y control estatal de las aguas, donde el poder político es manejado por un orden agroburocrático y agroadministrativo, características que podemos apreciar con amplitud en aquellas sociedades asentadas en la antigua Mesopotamia, Egipto, China, India y Mesoamérica (Wittfogel, 1966). Para el caso de los Andes podemos distinguir este tipo de control y administración estatal de las aguas durante el incario y mucho antes en el reino Chimú y Tihuanaco (Gelles, 1987)
