Does the Mixed-Ownership Reform Affect the Innovation Strategy Choices of Chinese State-Owned Enterprises?
Authors: Li Chunling , Yuan Runsen , Khan Muhammad Asif , Pervaiz Khansa , Sun Xiaoran
Published: March 2020

In recent years, the innovation of state-owned listed enterprises has gained substantial momentum in academic research due to their vital role in sustainable economic development. This article examines and evaluates the influence of mixed-ownership reform on the innovation strategy of Chinese State-Owned Enterprises (SOEs) from the two dimensions of ownership structure adjustment and control right allocation. We extend extant research in that: The diversity of mixed shareholders, the depth of mixed equity, and the control of mixed equity can significantly promote the exploratory innovation investment of SOEs. Our study investigates the impact of the shareholding ratio of foreign investors, natural persons, and institutional investors. The empirical results found a significant positive correlation between the increase of the shareholding ratio of institutional investors and the exploratory and exploitative innovation investment. On the other hand, private shareholders’ shareholding ratio has no impact on the innovation strategy choices of SOEs. Specifically, the results proved that the promotion of exploratory innovation investment by mixed-ownership reform is more significant in SOEs controlled by the central government or in competitive industries. To a large extent, this promotion is achieved by improving the proportion of executives with a professional R&D background in SOEs.
Comparing Religious Environmental Ethics to Support Efforts to Achieve Local and Global Sustainability: Empirical Insights Based on a Theoretical Framework
Authors: Zagonari Fabio
Published: March 2020

This paper develops a theoretical framework to assess the feasibility of environmental sustainability solutions, at local and global levels, based on the religious environmental ethics of several key religions: Hinduism (including Jainism), Buddhism (including Confucianism and Daoism), Judaism, Christianity (Catholicism, Eastern Orthodoxy, Protestantism), and Islam. Solutions are defined in terms of consumption (measured by GDP), environment use (measured by the ecological footprint), and welfare for representative individuals. Empirical insights for alternative religious environmental ethics focus on the relative importance attached to the consumption of goods (α) vs. involvement in a (local/global) community, and on the importance attached to the environment within the (local/global) community (μ). In terms of feasibility for national environmental problems (i.e., pairs of α and μ achieving sustainability, in countries where the religion is a majority) and consistency (i.e., coherence with the religion’s precepts) of policies for national environmental problems: Hinduism = uddhism > Islam > Judaism. Christianity produced no feasible solutions. In terms of effectiveness for global environmental problems (i.e., pairs of α and μ achieving global sustainability, if inequalities among nations are reduced in the future) and replicability for local environmental problems (i.e., pairs of α and μ achieving sustainability in countries where the religion is a minority): Hinduism = Buddhism > Judaism > Islam.

Published: March 2020

With the development of economic globalization, culture is a key factor supporting the sustainability of foreign direct investment (FDI), especially for multinational enterprises. This paper takes the Chinese capital market as a sample and, combined with interviews with managers of international joint-venture securities (IJVS), finds that the culture of participants formed in developed and emerging capital market has a significant impact on the performance of IJVS. Using the degree of price fluctuation to measure the risk culture of each capital market, this paper observes that the risk culture in the Chinese capital market is significantly stronger than that of developed countries. This paper also finds that the stronger the risk culture IJVS shareholders have, the better they can adapt to the environment of the Chinese capital market and the better the performance they can achieve. Furthermore, risk culture distance, calculated by the risk culture differences between foreign shareholders and Chinese capital market, are significantly negatively correlated with IJVS performance and efficiency.

Published: March 2020

The Kingdom of Saudi Arabia (KSA) is considered one of the countries with the highest consumption of electric energy per capita. Moreover, during the period of 2007–2017, the consumption rate increased from 6.9 MWh to 9.6 MWh. On the other hand, the share of residential electricity consumption in the KSA constitutes the biggest portion of the total electric consumption, which was about 48% in 2017. The objectives of this work were to analyze the exergy and assess the economic and environmental impacts of energy consumption in the residential sector of the Qassim region to determine potential areas for energy rationalization. The consumption patterns of 100 surveyed dwellings were analyzed to establish energy consumption indicators and conduct exergy analysis. The performances of different consuming domestic items were also examined, and energy efficiency measures are proposed. The average yearly consumption per dwelling was determined, and the total energy and exergy efficiencies are 145% and 11.38%, respectively. The average shares of lighting, domestic appliances, water heaters, and air conditioning from the total yearly energy consumption were determined.

Published: March 2020

Monitoring the ecosystem health for world natural heritage sites is essential for protecting them and benefits the formulation of more targeted protection policies. This study used Bayanbulak world natural heritage site as a case, established a framework for assessing the ecosystem health through remote sensing based on the parameters of ecosystem vigour, organization, resilience, and services. Then, we verified the obtained results through field sampling. The results show that the ecosystem health in the overall study area had declined over time, however, the health within the property zone remained at high levels and stable. The area proportion of low health was low and primarily distributed in the buffer zone. Thus, in general, the ecosystem in the study area was healthy. Besides, the ecosystem health exhibited distinct spatial agglomeration characteristics, and the degree of agglomeration enhanced over time. In addition, the field vegetation samplings were consistent with the changes in the ecosystem health levels, therefore, the result of RS monitoring of ecosystem health were credible. Thus, this study provides a scientific basis for heritage managers to formulate suitable ecological protection policies and should aid further research on the ecological monitoring of heritage sites.

Authors: Pugel Kimberly , Javernick-Will Amy , Koschmann Matthew , Peabody Shawn , Linden Karl
Published: March 2020

The international development sector is increasingly implementing collaborative approaches that facilitate a range of sectoral-level stakeholders to jointly address complex problems facing sustainable public service delivery, for which guidance does not explicitly exist. The literature on collaborative approaches has been built on experiences in high-income countries with vastly different governance capabilities, limiting their global relevance. A Delphi expert panel addressed this need by evaluating 58 factors hypothesized in the literature to contribute to the success of collaborative approaches. The panel rated factors according to their importance in low-income country contexts, on a scale from Not Important to Essential. Experts agreed on the importance of 49 factors, eight of which were essential for success. Rich qualitative data from open-ended responses revealed factors that may be unique to low-income country contexts and to service delivery applications, including how government capacity, politics, donor influence, and culture can influence decisions on structuring leadership and facilitation roles, appropriately engaging the government, and building legitimacy. Key considerations for future practice and research are summarized in a table in the appendix. This study contributes to both literature and practice by identifying the relative importance of factors to consider when designing collaborative approaches in low-income countries with limited governance capabilities.

Authors: Wang Yuchen , Marin-Lopez Alejandro , Jiang Junjun , Ledizet Michel , Fikrig Erol
Published: March 2020

Zika Virus (ZIKV) is transmitted primarily by Aedes aegypti mosquitoes, resulting in asymptomatic infection, or acute illness with a fever and headache, or neurological complications, such as Guillain-Barre syndrome or fetal microcephaly. Previously, we determined that AgBR1, a mosquito salivary protein, induces inflammatory responses at the bite site, and that passive immunization with AgBR1 antiserum influences mosquito-transmitted ZIKV infection. Here, we show that the active immunization of mice with AgBR1 adjuvanted with aluminum hydroxide delays lethal mosquito-borne ZIKV infection, suggesting that AgBR1 may be used as part of a vaccine to combat ZIKV.

Published: March 2020

In this paper, a 15 KW in-wheel motor (IWM) is taken as the research object, and the coupling factors among the electromagnetic field, temperature field and flow field are analyzed, and the strong and weak coupling factors between the three fields are clarified, and by identifying the strong and weak coupling factors between the three fields, a three-field coupling analysis model for IWM with appropriate complexity is established, and the validity of the model is verified. In a certain driving condition, the electromagnetic field, temperature field and flow field characteristics of IWM are analyzed with the multi-field coupling model. The result shows that, after the IWM runs 8440 s under driving conditions, in this paper, the IWM electromagnetic torque of the rated working condition is 134.2 Nm, and IWM the electromagnetic torque of the peak working condition is 451.36 Nm, and the power requirement of the motor can be guaranteed. The highest temperature of the IWM is 150 °C, which does not exceed the insulation grade requirements of the motor (155 °C), the highest temperature of the permanent magnet (PM) is 65.6 °C, and it does not exceed the highest operating temperature of the PM, and ensures the accurate calculation of components loss and the temperature of the motor. It can be found, through research, that the electromagnetic torque difference between unidirectional coupling and bidirectional coupling is 3.2%, the maximum temperature difference is 7.98% in the three-field coupling analysis of IWM under rated working conditions. Therefore, it is necessary to consider the influence of coupling factors on the properties of motor materials when analyzing the electromagnetic field, temperature field and flow field of IWM; it also provides some reference value for the simulation analysis of IWM in the future.
What is the Socio-Historical Method in the Study of Religion?
Authors: Slade Darren M.
Published: March 2020

The purpose of this article is to answer what the socio-historical method is when applied to the study of religion, as well as detail how numerous disciplines (e.g. archaeology, anthropology, sociology, psychology, philosophy, theology, musicology, dramatology, etc.) contribute to its overall employment. In the broadest (and briefest) definition possible, a socio-historical study of religion coalesces the aims, philosophies, and methodologies of historiography with those of the social and cultural sciences, meaning it analyzes the interpretation and practice of religion through the lens of social/historical contexts, scientific discovery, and from within each faith tradition. The result is that the contexts surrounding a particular religion becomes the primary subject of study in order to better understand the origin, development, and expression of the religion itself. This article explains that the socio-historical study of religion is, in essence, an eclectic methodology that focuses on describing and analyzing the contexts from which the interpretation and practice of religion occurs. The goal is to examine how different aspects of a religion function in the broader socio-political and cultural milieu. Its most fundamental postulation is that the social history of a religious community affects how it interprets and practices their faith. By approaching religious inquiry from a socio-historical perspective, researchers are better able to recognize religion as a cultural and institutional element in ongoing social and historical interaction. Three sections will help to explain the socio-historical method: 1) a definitional dissection of the term “socio-historical”; 2) an elaboration of the principles inherent to the methodology; and 3) a case study example of the socio-historical method in practice.
Agnomancy: Conjuring Ignorance, Sustaining Belief
Authors: Eller Jack David
Published: March 2020

Recent years have seen an increased interest in the construction and exploitation of ignorance, with the establishment of a field of agnotology (ignorance studies). This effort has focused almost exclusively on governments and corporations, though little or none on religion. After exploring work in agnotology and introducing the concept of agnomancy (the creation or conjuring of ignorance), the present article offers a preliminary application of these perspectives to religion, investigating what light agnotology sheds on religion and when and for what reasons religion engages in agnomancy.

Published: March 2020

One of the most challenging aspects in culture independent methods for foodborne pathogens’ detection is discrimination of dead and live microorganisms. This study aimed to determine the Vibrio parahaemolyticus in seafoods via direct plate counting (DPC) and toxR-based quantitative loop-mediated isothermal amplification (qLAMP) and to discriminate dead and live cells using propidium monoazide (PMA)-qLAMP. A total of 200 samples including finfishes (n= 100) and shrimps (n= 100), representing the Mediterranean, Black and Aegean sea were collected from supermarkets and fish markets of Konya-Turkey. qLAMP was performed in a Real-Time Turbidimeter and the time threshold (tt) values were yielded in 60 minutes. On DPC, the colonies grown on TCBS Agar was further confirmed by conventional PCR based from gyrB1 gene of Vibrio spp. and toxR gene of V. parahaemolyticus. Virulence property of the isolates were determined by tdh based qLAMP. The detection limit of the qLAMP was 1.2×104 CFU/g in artificially contaminated seafoods. DPC, qLAMP and PMA-qLAMP detected V. parahaemolyticus in 8 (4%), 12 (6%) and 12 (6%) samples, respectively. The CFUs of V. parahaemolyticus detected in qLAMP (5.96±0.10 log10 CFU/ml) and PMA-qLAMP (4.71±0.13 log10 CFU/ml) were higher than those of DPC (1.99±0.44 log10 CFU/ml) (P<0.05). The mean tt reduction in PMA treated samples was 1.25±0.38 log10 CFU/sample. The tdh gene was not detected in any of the isolates. In conclusion, the toxR-based PMA-qLAMP method could be an alternative to be used more widely and effective assay for the quantification of live V. parahaemolyticus in seafoods.

Authors: Syzenko Anastasiia , Diachkova Yana
Published: March 2020

In contemporary changing and innovative academic and working environment, tertiary schools need to rethink their approach to teaching and learning by gearing it towards the skills in most demand. Innovation in any sphere becomes more and more dependent on the collaboration between actors from very different backgrounds who combine their own expertise to create something new. This happens both on an individual- as well as on an institutional level. The organizations of the future will be forced to work more and more closely with people and institutional partners from all over the world in order to bring as many different perspectives and areas of expertise together as possible. This means that cross-cultural competence becomes one of the crucial factors in building a competitive profile of a prospective specialist. Therefore, this paper explores approaches to building cross-cultural competence using the English language as a tool and presents the findings of a pilot training on experimental collaborative cross-cultural project implemented with Master level Economics students in Ukraine. Qualitative and quantitative methods were used to collect the data and examine participants' language proficiency. The findings suggest that participation in collaborative technology-enhanced cross-cultural projects has a significant positive effect on learners’ language proficiency and develops their cross-cultural competence facilitating development of productive skills on the basis of receptive ones.
ENVIDENCE-BASED CERVIAL CANCER PREVENTION : 2010 UPDATES
Authors: Nguyen Vu Quoc Huy
Published: March 2020

HPV DNA testing and HPV vaccines are milestones in the new era of primary, secondary and even tertiary prevention of cervical cancer. Parallel to modern methods being used in hospitals and high-level settings, classical and simple methods, such as cervical cytology and especially visual inspection with acetic acid appear to be effective in screening cervical preinvasive lesions, especially at the limited-resource settings and grass-root level. Current management options for cervical intraepithelial neoplasia include observation, ablative methods and excisional methods. Ablative methods consist of cryotherapy, laser vaporization or electrocoagulation diathermy; excisional methods consist of cold-knife conization, laser conization, LEEP or hysterectomy. Their efficacy and complications rate are similar in removal of CIN, both in developed countries and in limited-resource settings.

Sera were quantitatively tested for HBeAg and HBV DNA. HBV genotyping was made by real-time PCR. Results: Among the 81 patients, 60.5% had genotype B, 26.7% had genotype C and 8.6% had mixed genotype B-C. Prevalence of symptoms (fatigue, anorexia, insomnia...) was higher in genotype C than in genotype B. Genotype C patients had positivity higher HBeAg than genotype B patients (56% vs. 38,8%, p <0.05). The rate of HBV DNA > 107 copies/mL was higher in genotype C group than in genotype B group (36% vs. 28,6%, p > 0.05). Conclusions: Most of the patients had genotypes B or C. Patients with genotype C had positive HBeAg and may be related to higher serological HBV DNA level than in genotype B.

Objective: HER2 may have a prognostic value in gastric cancer and test for HER2 overexpression help to select the patients for the targeted therapy with trastuzumab. Our aim was to study endoscopic properties, histopathology of gastric adenocarcinoma and their relationship with HER2 overexpression. Materials and Methods: Between 3/2010 and 05/2011, 64 patients with gastric cancer were tested for HER2 status by immunohistochemical staining of formalin-fixed paraffin-embedded endoscopic biopsy samples. Design: Cross-sectional study. Results: According to Borrmann, polypoid, fungating, ulcerated, and infiltrative type cancer. According to Lauren’s classification, 42.2% were intestinal, 57.8% were diffuse. According to WHO, 43.8% were tubular adenocarcinoma, 7.8% were mucinous adenocarcinoma, 17.2% were signet-ring cell carcinoma, and 31.3% were undifferentiated carcinoma. 29.7% were well-differentiated tumors, 18.8% were moderately-differentiated tumors, and 51.6% were poorly-differentiated tumors. HER2 overexpression was present in 23.5% of gastric carcinomas. 40% cardia tumors and 22% non-cardia tumors were HER2 positive. HER2 overexpressions were different between polypoid, fungating, ulcerated, and infiltrative types with rate of 30.8%, 37%, 6.3% and 0%, respectively (p = 0.04). HER2 overexpression of intestinal type tumors was higher than diffuse type tumors (37% vs 13.5%, p=0.04). HER2 overexpression in tubular adenocarcinoma, mucinous adenocarcinoma, signet-ring cell carcinoma, and undifferentiated carcinoma was 35.7%, 9.1%, 20% and 15%, respectively. 36.8% of well-differentiated tumors, 33.3% moderately-differentiated tumors, and 12.1% of poorly-differentiated tumors overexpress HER2. Conclusions: HER2 overexpression was found in 23.5% of gastric carcinomas and was associated to endoscopic properties, histopathologic type of tumors.

Amaç: Araştırma, gebelikte prenatal
bağlanma ve vücut algısı arasındaki ilişki ve etkileyen faktörleri belirlemek
amacıyla yapıldı.

Gereç ve Yöntem: Tanımlayıcı
ve ilişki arayıcı olarak yapılan araştırma, Temmuz-Aralık 2017 tarihleri
arasında Güneydoğu’da bulunan bir ilin kadın doğum ve çocuk hastanesi gebe
izlem polikliniğine başvuran 195 gebe ile yürütüldü. Veriler; Tanıtıcı Özellikler Formu, Prenatal Bağlanma
Ölçeği (PBE) ve Vücut Algısı Ölçeği (VAÖ) kullanılarak araştırmacılar
tarafından yüz yüze görüşme yöntemi ile toplandı. Tanımlayıcı istatistikler frekans, yüzde, ortalama,
standart sapma,  bağımsız gruplar
için t testi, Oneway ANOVA ve Pearson Korelasyon Analizi kullanıldı.

Bulgular: Araştırmaya katılan
gebelerin prenatal bağlanma puan ortalamalarının 43,84±9,71, vücut algısı
ölçeği puan ortalamalarının 94,03±20,35 olduğu ve aralarında anlamlı bir ilişki
olmadığı belirlendi. 31 yaş üstü (45,85±9,78), ilköğretim mezunu (46,30±9,51),
gebelik sayısı 3 ve üzeri olan (45,83±9,46) kadınlarda prenatal bağlanma puan
ortalamalarının daha yüksek olduğu bulundu (p<0,05). Gebelerin vücut algısı
ölçeği puanlarına yaş, eğitim durumu, ekonomik durum, gebelik haftası, gebelik
sayısı, düşük, planlanmış gebelik ve bebeğin cinsiyeti ile ilişkisi olmadığı
belirlendi.

Sonuç: Gebelerin PBE ile VAÖ
arasında bir ilişki olmadığı saptandı. Gebelerin, eğitim düzeyinin yükselmesi
PBE’yi olumsuz yönde etkilerken, yaşın artması, üç ve üzeri gebeliği olan
kadınların PBE puanlarının daha yüksek olduğu belirlendi. VAÖ puanlarının ise

Molecular Investigation of Paramecium bursaria Endosymbiotic Algae: the First Records of Symbiotic Micractinium reisseri from Kamchatka
Authors: Leśnicka Patrycja Zagata , Greczek-Stachura Magdalena , Tarcz Sebastian , Rautian Maria
Published: March 2020

Paramecium bursaria is a symbiotic ciliate species which cells contain hundreds of algae enclosed in perialgal vacuoles. The aim of the present study was to identify endosymbiotic algal strains of P. bursaria and to define the geographical distribution of the identified
species. We analyzed symbiotic strains of P. bursaria originating from distant geographical locations and housed at the Culture Collection of Ciliates and their Symbionts (CCCS) at St. Petersburg University. Based on the obtained results, we identified these strains as Micractinium
reisseri , Chlorella vulgaris, and Chlorella variabilis. We did not confirm the occurrence of a division into American and European groups and we guess that this division is only contractual and corresponds to the amount of introns in the 18S rDNA, and that there is no strong
correlation with the geographical location. We have demonstrated that the range of M. reisseri is greater than previously supposed. We identified algae strains originating from Southern Europe (Serbia), Western Asia, and from the Far East (Kamchatka) as M. reisseri. Moreover,
we identified two strains originating from Europe as C. variabilis, which also contradicts the predetermes about a division into American and European groups.
The Delphi Method in Information Systems Research
(2004‑2017)
Authors: Alarabiat Ayman , Ramos Isabel
Published: March 2020

Abstract: After almost 30 years of being used in the
information system (IS) discipline, only a few studies have focused
on how IS scholars apply the method's guidelines to design Delphi
studies. Thus, this paper focuses on the use of the Delphi method in
IS research. To do so, articles published between 2004 and 2017 in
the Senior IS Scholars' collection of journals of the Association of
Information Systems (AIS), describing Delphi studies, were analised.
Based on analysis of sixteen (16) retrieved IS studies, we concluded
that IS researchers have applied the method’s most important phases
and the procedural recommendations to promote rigor were considered
in the majority of the analised studies. Nonetheless, IS researchers
still need to include detailed information about (1) the steps taken
to ensure the validity of the achieved results, (2) better describe
the process of selecting and recruiting the experts, and (3)
experiment with innovative techniques to keep participants involved
in the Delphi process.
Problemas éticos de la investigación social en el nuevo orden tecnológico.
Authors: D´Odorico María Gabriela
Published: March 2020

La ética reflexiva es un modo de pensamiento acerca de las decisiones que se toman respecto de la investigación, de la producción de saber y de la intervención sobre la población. Es una dimensión de la filosofía que aporta una mirada para pensar la complejidad del campo epistemológico de las ciencias sociales, hoy en plena transformación. La complejidad del proceso de producción de conocimiento científico actual ya no permite separar un conocimiento puro de sus aplicaciones, hecho que lleva a utilizar como denominación más precisa la noción de tecnociencia. Entiendo que abrir una dimensión ética en la investigación social es, por un lado, delinear nuevos problemas epistemológicos que necesitan de un abordaje transdisciplinar. A la vez, y por otro lado, la dimensión ética muestra la necesidad de pensar en decisiones colectivas que incluyen distintos sectores institucionales y poblacionales comprometidos con la aparición del problema que se trate. Estas dos hipótesis atraviesan la totalidad de este escrito en el que se presentan algunos interrogantes y algunas indicaciones para posibles respuestas. Este trabajo constituye una síntesis de investigaciones previas de mayor alcance.
Criterios de información y predictivos para la selección de un modelo lineal mixto
Authors: García María del Carmen , Castellana Noelia , Rapelli Cecilia , Koegel Liliana , Catalano Mara
Published: March 2020

En los estudios longitudinales las unidades experimentales se observan repetidamente en varias ocasiones. Una herramienta importante para el análisis de este tipo de datos son los modelos lineales mixtos que permiten modelar las múltiples mediciones de la variable respuesta en función de las covariables y la correlación entre las mismas. La construcción de este tipo de modelos comprende la elección de covariables, la determinación del número de efectos aleatorios y fijos, y la especificación de la estructura de correlación del error aleatorio. Para la selección del modelo “óptimo” existe una amplia gama de criterios de información y predictivos. Los valores que proporcionan los paquetes estadísticos usan para calcularlos la formulación marginal del modelo, priorizando la inferencia sobre los parámetros poblacionales. Sin embargo, algunos autores argumentan que los efectos aleatorios individuales a menudo son de interés e introducen las versiones condicionales de los mismos. El propósito de este trabajo es presentar algunos de estos criterios tanto en su versión marginal como condicional e ilustrar su uso con datos provenientes de la Encuesta Permanente de Hogares. En la aplicación se observa que el desempeño de los mismos es disímil en términos de su comportamiento de elección.

La innovación y el enfoque de Responsabilidad Social como elementos indispensables en la actividad emprendedora de hoy
Authors: Navós Oscar , Noguera María Yohana , De la Fuente Lucila
Published: March 2020

La sociedad hoy está interesada en tener a disposición nuevos productos y servicios cada vez más personales que mejoren su calidad de vida y les proporcionen experiencias catalizadoras pero, por otro lado, también tiene mayor interés en los procesos de producción de los bienes y servicios que consume, en el impacto que generan las empresas en el medio ambiente y en el aseguramiento de condiciones de vida para las futuras generaciones.

Teniendo presente esa tendencia se realizó, a través de un relevamiento de fuentes primarias y secundarias, una revisión de algunos enfoques utilizados en la actualidad por los emprendedores de las nuevas generaciones, como son la innovación disruptiva y el pensamiento de diseño. Adicionalmente se efectuaron recomendaciones para lograr emprendimientos innovadores.

Forma parte también de este trabajo una primera aproximación teórica a los modelos de gestión conocidos como negocios sociales, emprendedorismo espiritual y neuroética, que se están instalando como nuevas formas de emprender responsablemente. En este marco, se deja una reflexión final sobre la principal diferencia que puede establecerse entre esos modelos de gestión responsable, la cual podría constituir el punto de partida de otros trabajos o investigaciones.
Concentración económica en cadenas agroindustriales de Misiones, Argentina: yerba mate, té y mandioca
Authors: Traglia Carla , Vidal Matías , Gortari Javier , Rosenfeld Víctor , Oviedo Alejandro
Published: March 2020

El perfil de las inversiones efectuadas en la región en los últimos 40 años contribuyó a profundizar el proceso de concentración de los recursos económicos, tanto en el agro como en la foresto-industria. Las políticas económicas neoliberales agudizaron estas tendencias, posibilitando una acelerada concentración de los canales de comercialización, que produjeron una abrupta caída de los precios de los productos agropecuarios, la precarización de las condiciones de trabajo agrario, el aumento de la desocupación y la expulsión de numerosos productores de sus tierras. En este artículo describimos y analizamos tres de los principales encadenamientos agroindustriales desplegados en el territorio de Misiones -yerba mate, té y mandioca- advirtiendo su importancia en la economía agraria contemporánea, así como la agudización de las desigualdades entre trabajadores agrarios, productores agropecuarios y las empresas involucradas en los procesos de elaboración y comercialización. En este sentido, sumado a las transformaciones en la organización de las actividades y las relaciones laborales, este trabajo indaga en las tendencias hacia la concentración económica en dichas actividades.
