Optimal labor market management under constraints in the form of a finite-dimensional system of nonlinear differential equations integrated by quadratures
Authors:   Perm National Research Polytechnic University, Gorbunov Daniil
Published: August 2023

The paper separates a class of finite-dimensional systems of nonlinear differential equations, the exact analytical solution of which can be represented in the form of quadratures. The paper uses a particular case of the system of the separated class as a set of equality constraints for the problem of optimal management of a closed finite-dimensional labor market with a common selection coefficient - the management parameter for the system under study. The paper specifies the definitions of the qualification categories for labor market subjects, with allowance for the physical meaning of their behavior in the system under study. It introduces quality factors for meeting the demand for labor, which are the averaged difference between the remuneration of labor and proceeds of the activities of subjects at each of the three qualification categories. It introduces a quality function in respect of the management of the labor market system, which is a sum of the products of the functions of the shares owned by the subjects at each of the three qualification categories by their quality coefficients. It considers labor markets with different ratios of quality factors. The case where the quality factor of subjects of a low qualification category is higher than that of a high qualification category has been shown to contradict the physical meaning of the model. Quality function vs management parameter curves are plotted for each labor market system under study. The paper gives examples of real-life labor markets for every physically admissible ratio of quality factors. The optimal management of the labor market system is shown to not necessarily imply that the management parameter tends to its extreme values. The paper plots a management quality function for a real-life labor market with a city-forming enterprise exemplified by the labor market of the village of Sylva, the Perm Territory, and determines the optimal values of management parameters.

Published: August 2023

A full-fledged empirical test of the latest methodology in the field of recursive procedures for identifying and dating market bubbles - the GSADF test - has been performed. The use of previous iterations of recursive tests did not allow to accurately determine the presence of a market bubble at the early stages of its formation. The results of this study prove that the GSADF test using a sliding window significantly improves the discriminatory ability of recursive tests, at the early stages of formation it allowed to detect such episodes of stock market collapse as the Japanese economic bubble of 1986-1991 and the dot-com bubble in the USA in 1995-2001. Testing based on current market data demonstrates the formation of a market bubble in the NASDAQ stock index since August 2020.

Introdução: A artrite reumatoide (AR) é tratada com drogas modificadoras da doença (DMARDs) convencionais e biológicas. Objetivos: Comparar a sobrevida de medicamentos biológicos utilizados para o tratamento de pacientes com AR. Método: Estudo retrospectivo de prontuários de pacientes que utilizaram medicamento biológico para tratamento de AR de janeiro de 2020 a janeiro de 2022 e este foi suspenso. Dados acerca das causas de retirada, tempo de uso, dados epidemiológicos, clínicos e de comorbidades foram coletados. Resultados: O principal motivo da descontinuidade foi a falha seguida por efeitos colaterais. Infliximabe e adalimumabe foram os que apresentaram maior sobrevida. IMC (índice de massa corporal) e o tabagismo, sexo e idade não mostraram interferência nesta sobrevida Conclusão: Falha é a causa mais comum de descontinuidade dos biológicos. Dentre os fatores estudados (fumo, IMC, idade e sexo) não foi possível identificar variável que se associasse com falha.

Published: August 2023

Cancer is a leading cause of death worldwide. The current cancer treatments including chemo-, radio- and immuno-therapies pose various side effects, and chances of recurrence that demand for new therapeutics to overcome the issues with existing ones. Mushrooms are considered a potential source of novel therapeutic agents. Ganoderma colossus, a non-edible wood-inhabiting mushroom, is known for certain medical properties. The present study aimed to investigate the possible anticancer activity of methanolic, ethyl acetate, and chloroform extracts of G. colossus, against MCF-7 cells and the mechanism of action(s). MTT assay and gene expression studies were carried out by following the standard protocols. The results demonstrated that among the three solvents, the ethyl acetate crude extract of the mushroom exhibited potential cytotoxic activity on MCF-7 (IC50, 17.2 ± 2.7). The DNA damage induced by the solvent extracts of G. colossus was observed by H2AX foci formation. The TP53 over-expression and flow cytometry analysis indicated that checkpoint activation followed by cell cycle arrest occurred at G1/G0 phase in response to the extract treatment. The dual acridine orange/ethidium bromide (AO/EB) staining revealed apoptosis-associated changes in the cells. Analysis of caspase 3 activations by immunophenotyping confirmed the apoptotic process in the extract-treated cells. Bcl-2 and TP53 mRNA expression data by RT-PCR disclosed the apoptosis pathway. The GC- MS spectral data of the ethyl acetate crude extract of the mushroom indicated the presence of molecules capable of inducing apoptosis. The present study warrants further studies to isolate the molecule(s) from G. colossus which may be a potential drug candidate for breast cancers.

Potential Health Risks of Chloroacetanilide Herbicides: An In Silico Analysis
Authors: BERBER Ahmet Ali , DEMİR Şefika Nur , AKINCI KENANOĞLU Nihan
Published: August 2023

The extensive use of herbicidal products in agriculture and forestry has raised concerns over potential adverse effects on human health and the environment. Chloroacetanilide herbicides are a group of synthetic chemicals used to control weeds in agriculture and forestry. However, so[me of their members have been characterized as possible carcinogens. The genotoxicity and carcinogenicity of two chloroacetanilide herbicides, delachlor and xylachlor, are discussed. This article proposes to use tools to predict their potential toxicities based on their chemical structure. Four software tools, Vega Hub, Toxtree, Lazar, and TEST, are used to predict the potential genotoxic and carcinogenic effects of the herbicides. Vega Hub uses QSAR models, Toxtree uses a decision tree approach, Lazar uses data mining algorithms, and TEST uses QSAR methods to estimate toxicity. The canonical Simplified Molecular Input Line Entry Specification (SMILES) systems of delachlor and xylachlor are entered into each software tool to create a prediction. The study found that delachlor and xylachlor is a class 3 highly toxic compounds with potential mutagenic and carcinogenic effects based on Toxtree and Vega Hub. Meanwhile, Lazar and TEST predicted that delachlor and xylachlor are unlikely to be mutagenic. This study to determine the toxicity of the herbicides delachlor and xylachlor has shown that the possible effects of these herbicides on health and the environment need to be further investigated. The results provide valuable insights into chloroacetanilide herbicide toxicity and help develop safer, more environmentally friendly alternatives.
Sub-surface Geological Modeling Based on Gravity Residual Data in Adang Volcanic Rock Area, Mamuju, West Sulawesi Province

Published: August 2023

The Mamuju area of West Sulawesi Province is composed of Adang volcanic rock that is a product of the process of volcanism in a volcanic complex with an eruption center and several lava domes. The geology of the study area is composed of eleven rock units, namely Adang breccia, Adang lava, lava dome, volcanic conglomerate, Ampalas breccia, Malunda breccia, Boteng lava, Tapalang breccia, limestone, reef limestone, and alluvium. The mineralization of uranium, thorium, and rare earth elements formed in Adang lava thorianite veins. Adang lava is intruded by a dioritoid found in the Mamuju river upstream. The gravity modeling technique has produced two 2-D subsurface models based on gravity data on 2-D cross-sections of the residual gravity map. It is known that the rock density range from 2.10 to 2.85 g/cm3 in the study area. Based on the interpretation of two 2-D subsurface models, a batholith, a giant-sized intrusive rock, is found in the southeastern part of the study area with a rock density of about 2.85 g/cm3 and is interpreted to be dioritoids. Furthermore, deep intrusion rocks also occur in the center part of the study area with a rock density of 2.8 g/cm3. It is estimated to be the same as the rock in the southeastern part of the study area. Dioritoid intrudes a volcanic breccia sedimentary rock with a density of about 2.1 g/cm3.
Review on Granitic Rocks in Sumatra: Intrusion Process, Classification, Mineralization and Potential Uses
Authors: Irzon Ronaldo , Syaeful Heri , Kusworo Aries , Wahyudiono Joko , Ngadenin Ngadenin
Published: August 2023

Granitic rocks are widely distributed in Sumatra and surrounding areas. These granitoids are classified into several granite provinces of Southeast Asia with different intrusion processes and specific characteristics. This paper aims to review the intrusion of granitic rocks in Sumatra and describe the opportunities associated with it. Granite rocks are used to manufacture cultural heritage, works of art, and ornaments because of their weathering resistance, color diversity, and hardness characters. S-type granite intrusion in Sumatra might be associated with tin mineralization while silver-gold with the I-type. Theoretically, granite contains more REE than other igneous rocks. Mining and extraction difficulties complicate the direct REE exploitation from fresh granite. A-type granite relatively contains more REE than the other types, but this type of granite is not correlated with certain provinces. Indonesia has a tropical climate which is prone to weathering. Therefore, it is possible for REE and/or bauxite enrichments in the granite weathering horizon. Granite is assumed to be a potential source of uranium and thorium, especially for the S-type, because it is formed through the compression of sediments that can absorb these radioactive elements from the continental crust.

Propagation of the plane acoustic wave along the center line of two liquid spherical drops placed into a space filled with another liquid is under investigation. An approach is elaborated to characterize the interaction between the liquid drops caused by the acoustic radiation forces that are the time-constant components of hydrodynamic forces acting upon the drops located in the outer liquid. Investigation of the acoustic radiation forces influencing the drops in the acoustic field is performed in the frame of two-step procedure. The first step comprises solution of the linear problem of incident wave diffraction on the drops while the second one is calculation of the hydrodynamic forces acting upon each spherical drop followed by time averaging of forces determined. The analytical formula for the acoustic radiation force calculation is derived for the case under consideration.

Türkiye’nin göç yönetimi konusunda bakanlık düzeyinde; ülkeye yasa dışı giriş yapan yabancıların engellenmesi, giriş yapan yabancıların planlanması, kontrolü, öncelikli ihtiyaçlarının karşılanması, insani yaşam sürmeleri için birtakım önlemlerin alınması, ev sahibi topluma entegrasyonu ve yine ev sahibi ülkenin kültürü, ekonomisi, çalışma hayatı, güvenlik, eğitim ve sağlık alanlarında neden olduğu etkilerin yönetilmesi için alınan kararlar ve bakanlık teşkilatlarında başkanlık/müdürlük/birimler oluşturulmuştur.
Türkiye’de göç yönetimi alanında en kapsamlı görev, yetki ve faaliyetleriyle İçişleri Bakanlığı öne çıkmaktadır. İçişleri Bakanlığı teşkilatı içerisinde Göç İdaresi Başkanlığı adıyla merkez, taşra ve yurt dışında hizmet birimleri bulunan bir idari birim bulunmaktadır. Türkiye’nin düzensiz ve kitlesel göçlere yoğun olarak maruz kaldığı dönem sonrası 2013’te kurulan Göç İdari Başkanlığı yanında yabancıların eğitimine ilişkin konularda Milli Eğitim Bakanlığı bünyesinde “Göç ve Acil Durumlarda Eğitim Daire Başkanlığı” sağlık boyutuyla Sağlık Bakanlığı bünyesinde “Göç Sağlığı Hizmetleri Daire Başkanlığı”, çalışma hayatıyla ilgili alanda Çalışma ve Sosyal Güvenlik Bakanlığının “Uluslararası İşgücü Genel Müdürlüğü”, Dışişleri Bakanlığı bünyesinde “Göç İltica ve Vize Genel Müdürlüğü” birimleri bulunmaktadır. Bakanlık nezdinde oluşturulan herhangi bir idari birimi bulunmayan ancak Türkiye’deki başta Suriyeliler olmak üzere diğer geçici koruma altındakiler ve yabancılar için çeşitli politikalar geliştiren, faaliyetler organize eden Aile Ve Sosyal Hizmetler Bakanlığı da aktif olarak göç yönetimi alanında görev alan bir bakanlık olarak görülebilir. Diğer taraftan göçün önemli ve belki de yıkıcı etkilerinin görülebileceği bir diğer boyut kültür alanıdır. Bu alana ilişkin olarak Turizm ve Kültür Bakanlığı da göç yönetim sürecinin bir aktörü olarak görülmelidir. Bunun yanında Spor Ve Gençlik Bakanlığı ile Çevre, Şehircilik Ve İklim Değişikliği Bakanlığı gibi bakanlıkların göç alanına ilişkin konularda proje ve faaliyetlerinde ciddi bir eksikliğin bulunduğu da göze çarpmaktadır. Çalışmada bakanlıkların göç yönetim sürecindeki rolleri ve idari yapıda göç yönetimini konu alan birimler etraflıca değerlendirilmekte, öneriler sunulmaktadır.

Authors: Mengue Carolina , Pellanda Lucia , Parodi Maurizio , Vilela Manuel
Published: August 2023

Background: Among congenital diseases, congenital heart disease is one of the most frequent defects, accounting for high morbidity and mortality rates. Coexistence of ocular sequelae, especially in retinal microvascularization, is frequent, and may be a marker of vascular damage and severity of underlying disease. Aims: To identify ocular anatomical repercussions in children with congenital heart diseases; to describe the prevalence of potential markers associated with retinal vessels using a smartphone. Methods: This was a cross-sectional observational study with children diagnosed with congenital heart disease treated at the Instituto de Cardiologia in Porto Alegre-RS from 4 up to (but not over) 18 years old. Results: Of a total of 218 patients assessed, 206 were included in the study. Mean age was 10.19 years +- 3.88. Uncorrected visual acuity poorer than 0.6 in at least one eye was found in 11.65% (24) of all patients. Regarding retinal findings, estimated mean arterial tortuosity was 437.79 μm, and estimated mean venous tortuosity was 336.41 μm. Taking only the cyanotic group, the arterial mean reached 557.29 μm, and the venous mean reached 401.86 (p=.001 and p=.004, respectively). In the multivariate analysis, estimated mean arterial tortuosity of cyanotic patients undergoing clinical treatment was 699.13 μm versus 489.74 μm for those without clinical treatment (p<0.001). Conclusion: Presence of retinal vascular tortuosity, especially in the arterial bed, is associated with cyanotic CHD. Identification of ocular changes, especially through an easily accessible and universal method such as the smartphone, may have diagnostic and prognostic significance.
Is there a Role for Primary Surgical Resection in the Palliative Rectal Cancer Setting: A Systematic Re-view
Authors: Alfred Joshua , Clifford Rachael , Dixon Steven , Kalaiselvan Ramya
Published: August 2023

Introduction: There are over 42,000 new cases of colorectal cancer diagnosed every year in the UK alone, a third of those being rectal in origin. Although there has been significant progress in the treatment of rectal cancer, overall, 5-year survival can still be as low as 17% for those with advanced disease. We aimed to assess the impact on of overall survival and quality of life of primary tumour resection in the palliative setting. Method: A literature search was performed using Pubmed and Cochrane databases in March 2022. Bias was assessed using the Joanna Briggs institute checklist. Results: Seven papers were included in the review; all retrospective cohort. A total of 809 patients underwent rectal resection in the presence of metastatic disease +/- adjuvant therapy. The median age was 61years, 59.7% male. 68.6% of patients presented with liver metastasis at the time of diagnosis. The most commonly reported symptoms preoperatively were bleeding and tenesmus. 4-50% of patients in each cohort underwent neoadjuvant therapy. Highest 30-day mortality reported was 7.3%. Both studies comparing resection v none demonstrated a higher overall survival for those undergoing surgery, with one showing 1year overall survival 65v20%. Quality of life was not addressed across the literature. Conclusion: Although there is some evidence to show a favourable overall survival for patients undergoing primary tumour resection in the palliative setting, this data is mainly old and across a heterogeneous population. A larger scale prospective study would be required to assess its potential role and impact upon quality of life.

The innovative I-SPY Breast Trial is presented as an example of an unusually patient-centric clinical trial that has been significantly impacted by extensive advocate involvement. In the introduction we briefly define what we mean by patient-centric trials and describe the overall structure, goals, and evolution of I-SPY. We then describe: 1) the roles and philosophy of advocate involvement; 2) attributes of the trial design that make it especially patient-centric; and 3) educational material and communications approaches aimed at empowering and supporting trial participants. For each section, in addition to describing I-SPY practices, we provide aspirational suggestions that could enhance I-SPY and/or other clinical trials. Embedding advocates into every aspect of clinical trial design and operations, empowering trial participants with excellent patient educational material and incorporating and learning from patient-reported outcomes serves as a model approach to achieve more patient-centric clinical trials.
Long-Term Survival of a Dog With Hepatocellular Carcinoma Under Treatment with Viscum Album – Case Report
Authors: Valle Ana , Carvalho Aloísio
Published: August 2023

Hepatocellular carcinoma is the most common liver neoplasm in dogs and can be treated by the Viscum album therapy in a curative or palliative way. The objective is to report a hepatocellular carcinoma case in a dog treated by homeopathic therapy, extending to Palliative Care, with a 24-month survival. A 12-year-old Schnauzer male with a history of a liver nodule was treated by intravenous and subcutaneous applications of V. album in different dynamization and combinations, chromotherapy, and oral homeopathic medicines. The tumor growth was controlled, and the health condition of the patient was stable while the medication was given as prescribed. However, as application frequency was reduced, tumor growth increased, and health deterioration was verified. Nevertheless and contrary to expectations, the patient had a 24-month survival. Therefore, these findings point to the potential of V. album on enhancing the quality of life, controlling tumor growth, and prolonging survival in patients with hepatocellular carcinoma. Patients under continuous treatment would benefit better from these properties.

A collaborative, interdisciplinary approach within the medical field is of paramount importance, aiming towards fostering an environment conducive to healthy aging in patients. It is incumbent upon us to thoroughly assess the ramifications of cardiovascular influence on cerebral functions and to instigate therapeutic interventions at an early stage, or preferably, preventive measures. This text emphatically reinforces the substantial influence of arterial hypertension on the central nervous system, concurrently suggesting a feasible methodology for its measurement. The aim of this publication is to foreground this problem, thereby catalyzing scientific dialogue, advocating for research proposals, and potentially instigating a reconsideration of our patient care approaches.
Culture of Honor and COVID-19: Regional Mitigation Efforts in the United States During the Pandemic
Authors: Baughman Kiersten
Published: August 2023

As the COVID-19 pandemic struck in early 2020, states in the United States (U.S.) varied widely in the arrival of the first case of the virus, the official response of government officials and citizens, and the overall impact of the virus. The Culture of Honor, a reputation-based system more prevalent in the U.S. South and West, is linked with lawlessness or mistrust of the law where it exists, fierce independence, and condones aggressive behaviors, particularly in response to threat. The current project explored the influence of the Culture of Honor on perceptions of the legitimacy of COVID-19 messaging, government actions and citizens responses, and overall impact of the pandemic at the state level. It was predicted that the overall numbers of citizens infected by COVID-19 would be higher in culture of honor states, that any actions taken by government officials would be strict and perceived negatively by citizens residing in culture of honor states, and that citizens would be unlikely to follow any imposed government restrictions. Publicly available data were compiled for each of the U.S. states including total number of COVID-19 cases, total deaths, how the elected officials managed any coordinated response (such as issuing executive orders, any stay-at-home or lockdown orders), and coded evidence of citizens violating any of these orders such as by protesting or showing up at public locations that were currently closed. I am deeply indebted to Luke Conway for providing access to an individual-level dataset collected via Amazon Mechanical Turk (MTurk) that included 978 people from across the U.S. who had responded to items related to these variables of interest. Analyses indicated that individuals in US states identified as Culture of Honor had seen greater impact to their states of the COVID-19 pandemic as of 2020 in several ways, including higher total number of citizens who tested positive and also died from COVID-19, less support for government action to mitigate the spread, and stronger distrust of information shared by their state authorities about the pandemic. These findings indicate that cultural values including the Culture of Honor could impede state-level attempts to thwart the spread of contagious diseases and other measures intended to protect individuals.

What Can Parents Do with Cyberbullying Among Adolescents?
Authors: Cao Lingfei
Published: August 2023

In recent years, cyberbullying, as a new form of bullying, has become more prevalent among adolescents who were born in the digital era. What helps prevent adolescents from participating and/or being victimized in cyberbullying is becoming a popular topic. Although past literature on traditional bullying has mostly focused on the effective intervention strategies taken by schoolteachers, educators, and peers, we cannot ignore the role parents are playing in preventing cyberbullying among adolescents, which appears to happen more often at home or out of school. The current study reviewed a great number of papers that emphasize effective parental intervention as a protective factor for cyberbullying in adolescents. According to our review, the main influential factors are family environment, parental control, and parental knowledge. In conclusion, our review suggested building better parent-child relationships and communication, adapting autonomy-supportive parental control strategy, and as well as advancing parents’ knowledge of internet use led to effective parental intervention and protection in adolescents’ cyberbullying.

Published: August 2023

Purpose: This study is focusing on the mental health issue of Japanese who had been left behind in mainland China in confusion after World War Ⅱ in 1945, then returned to Japan due to the policy with the normalization of diplomatic relations between Japan and China in 1972. Their language, customs, values, etc., are tinged with the temperament of the Chinese cultural region. This study reports on the changes in mental health issues among the returnees over time. Method: This study investigates original papers published after 1972 when diplomatic relations between Japan and China were normalized. Moreover, we quote Ichushi (Japan Medical Abstracts Society)- Web, the most used medical publications database in Japan. As an ethical consideration, we quoted the original text as faithfully as possible so as not to infringe copyright. Result: Eleven prior research from the original papers were analyzed in this study. The research at that time were peaked in 1990. Also, the period of the research was conducted in three separate times, 1st, over three and ten years after returning to Japan. In the early years, many studies focused on psychological adjustment and analysis of background factors. Since the beginning of the 2000s, health concerns increased due to the aging. Many returnees had mental health problems, language barriers and cultural differences economic anxiety and the lack resources, and they had continued to be psychological causes of mental health. Conclusion: Mental health problems among China returnees remained a serious health problem even after a long period of time. For aging Chinese returnees to lead safe and happy lives in Japan, it is important to provide Chinese-language care services and have an abundance of spirituality. In addition, the effort to take cultural differences into account for the health supports and nursing care services is also essential.
Discuss on the Distinguishing Standard of Serial Images and Their Copyright Protection
Authors: Zhang Yanan
Published: August 2023

Under the provisions of China's current copyright law, audiovisual works and video recordings as two separate objects with different degrees of protection. This article attempts to explain the ambiguity of the criteria for distinguishing the audiovisual works and video recordings in judicial practice and proposes the following solutions: when distinguishing audiovisual works and video recordings by the presence or absence of originality, serial images that faithfully record existing images should be excluded, and according to the dichotomy of image and content, the three links of visualization of process events, raw image shooting and editing production should be refined in the judgment criteria. Since it is difficult to make direct distinctions within audiovisual works, this paper converts them into distinctions of producers according to the different situations of claimants as an aid.

Impacto de los programas de mejoramiento de vivienda por autoconstrucción: evidencia para barrios populares de Argentina
Authors: Vasquez Claudia , Lince Matías
Published: August 2023

A fines de 2021, Argentina implementó un programa de mejoramiento de vivienda por autoconstrucción destinado a mujeres residentes en barrios populares de todo el país. Al superar las inscriptas el número de cupos disponibles en cada convocatoria, la asignación de los subsidios se realizó a través de una serie de sorteos. Explotando la asignación aleatoria del programa, el objetivo de este artículo es evaluar el impacto en cuatro dimensiones: la calidad de los materiales de la vivienda, el grado de hacinamiento, la salud de los niños y las percepciones generales del hogar sobre su bienestar psicosocial. Los resultados sugieren que, ocho meses después de la asignación al programa, se observan impactos significativos y de magnitud considerable en las dimensiones estudiadas. Como consecuencia de acceder al subsidio, el incremento en la probabilidad de tener piso y techo de materiales resistentes y con elementos de terminación es del orden del 46% en el caso del piso y 21% para el techo. El programa también aumenta 47% la probabilidad de no sufrir hacinamiento en el hogar. A su vez, se observa un efecto considerable en el bienestar subjetivo de las beneficiarias y en sus percepciones sobre la seguridad, privacidad, salud, convivencia familiar y calidad del sueño. Por ejemplo, el programa incrementa la probabilidad de considerar como “muy seguras o bastante seguras” las condiciones de los cerramientos de puertas y ventanas (91%), de la instalación eléctrica (31%) y las condiciones generales para preservar la salud de niños, niñas y adolescentes (60%). El subsidio también incrementó las probabilidades de estar “de acuerdo o muy de acuerdo” con que el espacio es suficiente para la buena convivencia (69%), las divisiones internas garantizan la privacidad (64%), o de considerar “bueno o muy bueno” el estado de salud (9%) y la calidad del sueño de los miembros de la familia (48%).

En el marco del proyecto del BID “Analysis of the fiscal impact of post-Covid recovery policies in a decarbonization context for the countries of the Andean Region”, el estudio “Bases para impulsar una minería sostenible y responsable: Una ventana para dar un salto de prosperidad en el siglo XXI” buscó, desde una mirada estratégica, generar una primera aproximación hacia una minería sostenible y responsable centrada en la gran y mediana minería metálica, especialmente de cobre, de Colombia y Ecuador. Este tipo de minería se define como aquella que es capaz de generar valor a través de dinámicas de acción colectiva que minimizan los daños ambientales y fortalecen las distintas formas de capital necesarias para crear valor económico, social y ambiental sostenible para las generaciones actuales y futuras. Para lograrlo la minería debe ser capaz de fortalecer el capital creado, tanto humano como natural en las economías mineras y, en particular, el capital existente a nivel de los territorios donde se realiza. La visión subyacente es que al concluir un ciclo minero exploración, desarrollo, operación y cierre la minería deje un legado positivo en términos de mayor capital humano y natural, excluyendo el capital mineral que se extrae y no se renueva.
A Personalized VAT with Capital Transfers: A Reform to Protect Low-Income Households in Mexico
Authors: Kotlikoff Laurence J. , Lagarda Guillermo , Marin Gabriel
Published: August 2023

The Value-Added Tax (VAT) is the most prevalent consumption tax globally, yet it is frequently deemed highly regressive. To address this, we propose a Personalized VAT (PVAT) devised in conjunction with a distributional policy. We aim to achieve three objectives: increase revenue collection, achieve progressivity, and disrupt the intergenerational dependency of low-income households. We use Mexico as a case study, showing that eliminating all special VAT regimes and standardizing the rate at 16% could contribute an additional 2.2% of GDP to fiscal revenues. However, such a reform could have severe negative welfare impacts on the poor. To tackle this dilemma, we propose several PVAT scenarios. Our results indicate that a PVAT could be fiscally neutral or even increase revenues by up to 0.83% of GDP, while benefiting the lowest-income households. Lastly, we analyze the general equilibrium effects of a PVAT and various distributional policies, including lump-sum and capital transfers. For this purpose, we employ an overlapping generations model calibrated for Mexico. Our simulations reveal welfare enhancing and output growth results through a PVAT policy that includes capital transfers, thereby presenting a viable strategy for breaking intergenerational dependency.
Desarrollo Agtech en la Región Andina: casos de éxito y lecciones para el futuro
Authors: Bert Federico E. , Lachman Jeremías , Del Río Juan Andrés
Published: August 2023

En los últimos años, la región andina ha sido testigo de un proceso de expansión del ecosistema de innovación agtech. Los emprendimientos agtech son firmas de servicios basados en conocimiento que utilizan tecnologías innovadoras, en especial digitales. Las empresas de agtech surgen de la combinación de múltiples herramientas como big data, inteligencia artificial (IA), internet de las cosas (IdC) y blockchain, las cuales pueden aplicarse sobre diversos eslabones de las cadenas agrícolas, ganaderas y agroindustriales, y cuyos servicios se prestan típicamente mediante plataformas digitales. En esta dirección, el ecosistema de innovación agtech da cuenta de amplias posibilidades de generar transformaciones en toda la región, mejorando la eficiencia de diversos procesos a lo largo de las cadenas de valor agroalimentarias, reduciendo el impacto ambiental, generando inclusión en productores rurales de baja escala y, en algunos casos, contribuyendo al desarrollo de nuevos productos como bioenergías, biomateriales, alimentos novedosos, etc. Este trabajo tiene como objetivo identificar los elementos que contribuyeron al surgimiento y desarrollo de emprendimientos agtech en la región andina, así como también determinar los obstáculos que están limitando un mayor desarrollo del ecosistema, de modo tal de sugerir espacios de acción en materia de políticas públicas. Con este propósito, para el estudio se realizó un mapeo de las empresas agtech actualmente vigentes en la región, y se analizaron diez casos en profundidad -ocho firmas originadas en países de la región, y dos fuera de esta, una de Argentina y otra de Brasil. Para cada una de estas diez empresas se analizaron las propuestas de valor, los impactos productivos y ambientales de las soluciones desarrolladas, los antecedentes del equipo fundador, las fuentes de financiamiento, el proceso de desarrollo tecnológico que sustenta los servicios, así como los obstáculos al crecimiento y las perspectivas futuras de las empresas, entre otros temas. A partir de las lecciones aprendidas se propone una serie de líneas de acción o intervenciones de políticas públicas que podrían contribuir a potenciar el mundo agtech en la región andina.
Entrepreneurial participation depth on household risky financial asset allocation
Authors: Zhang Limiao , Zhang Wenjia , Wang Yancong
Published: August 2023

This paper aims to investigate the impact of entrepreneurial participation depth on household risky financial asset investments. The issue is examined using Probit and Tobit models based on the data of the 2017 China Household Financial Survey. First, the depth of entrepreneurial participation of entrepreneurs has a significant negative impact on whether their families participate in the risky financial market. Second, the more assets invested in entrepreneurship, the fewer households invest in risky financial markets. In addition, the depth of entrepreneurial participation would further squeeze out the degree of involvement in the risky financial market based on risk diversification and liquidity demand. Finally, the crowding out effect of entrepreneurial participation depth on household financial asset allocation differs between urban-rural duality and trust degree. This study further explains the mystery of limited participation in the risky financial market, helps understand the background risk characteristics of entrepreneurial families, promotes the scientific allocation of risky financial assets of related families and the stable operation of the risky financial market.

O Povo Wai Wai e o Multilinguismo entre os Indígenas do Território Wayamu
Authors: Chagas Angela F. A. , Cunningham Lúcia M. S.
Published: August 2023

Este artigo tem como objetivo apresentar o contexto multilíngue dos diversos povos indígenas que habitam o Território Wayamu, na fronteira do Brasil (PA, AM e RR) com a República da Guiana – falantes em sua maioria de línguas da família Karib, mas também de linguas Aruák, além do português e do inglês. Discutimos ainda alguns fatores históricos e sociais que levaram o Wai Wai à condição de língua franca utilizada pelos povos que habitam essa região. Para isso, resgatamos o histórico de contato com os não-indígenas, o histórico de migrações, o histórico de relações interétnicas e o processo de conversão religiosa cristã dos Wai Wai; além da assimilação de uma “identidade Wai Wai” por outros grupos indígenas, que ficou conhecida como “waiwaização”.
A língua geral amazônica no Grão-Pará cabano: revisitando conceitos
Authors: Lavareda Welton Diego Carmim
Published: August 2023

Trata-se de um estudo que problematiza a utilização do termo “língua geral” referindo-se à amplitude de uso do patrimônio linguístico mobilizado pelos cabanos à época da Cabanagem. O processo de teorização dos conceitos ocorrerá por meio de um diálogo entre os escritos de Michel Foucault no quadro dos estudos discursivos (2010a; 2010b), Rosa Silva (2004) e Dante Lucchesi (2015), na busca de desmembrar gestos interpretativos que tornem mais plural o olhar sobre o projeto lusitano de governo da língua portuguesa como manifestação linguística oficial do Brasil. Assim, pela perspectiva de discursivização das línguas potencializada pelo dispositivo colonial, limitaremos alguns acontecimentos discursivos em suas especificidades para reagrupá-los em uma rede de memória, observando a hipótese de indícios que possam evidenciar o nheengatu como uma língua crioula no Grão-Pará cabano e, ao mesmo tempo, como mais um traço cultural solidificado por diferentes grupos sociais do território amazônico para fazer valer seus interesses.
A língua é viva: um caso de neologismo na sala de aula de uma escola do campo
Authors: Oliveira Ecilia Brada de
Published: August 2023

A língua é complexa, viva, social e histórica, com o tempo transforma-se. Isso posto, léxico novos surgem e outros desaparecem, cabendo ao professor de língua portuguesa mediar o processo ensino-aprendizagem do sistema linguístico levando em consideração essas características sem ignorar os fatores extralinguísticos também. Nessa perspectiva, essa pesquisa analisa um caso de neologismo identificado em uma escola do campo no estado do Pará. A metodologia usada na investigação é a pesquisa-ação. O objetivo geral - trabalhar a língua por meio da perspectiva sócio-histórica de Bakhtin, explorando o uso de um neologismo identificado no retorno às aulas presenciais no primeiro semestre de 2022. Para isso, pautou-se em estudos de Thiollente (2009), Bakhtin (1997); Foucault (2006); Fairclough (2016) e Câmara Jr. (2009). Conclui-se, assim, que os neologismos surgem em contextos urbanos e rurais de forma bastante dinâmica e inusitada (neste caso, internalizado e disseminado no ápice do isolamento social) às vezes, naturalizar-se à língua, mas que, em alguns casos, desaparecem e/ou passam despercebidos ao olhar do professor de Letras, caso ele não esteja em constante formação. Espera-se com isso que outros professores/pesquisadores se atentem para o fenômeno linguístico usado, explorando-os de forma sistemática, principalmente, os dos contextos regionais.
