Authors: Li Haiyan , Guo Jiang , Zhang Dong , Huang Jihong , Li Xuejia
Published: February 2022

Osteoporosis is one of the common degenerative skeletal diseases whose essential mechanism is the imbalance between bone resorption and formation. Currently, the close coordination of signaling pathways at genetic level during bone development is a hot topic of osteoporosis research. The present study is focused on whether pterostilbene protects against hydrogen peroxide (H2O2)-induced osteoblastic cell apoptosis, oxidative stress, and reveals the related underlying mechanisms. MC3T3-E1 osteoblastic cells were cultured and treated with different concentrations of H2O2 (0–1 mM) along with or without pterostilbene, and MTT assay or Annexin V-FITC/propidium iodide staining was applied for measuring cell viability and apoptosis. The in vitro cellular antioxidant analysis was performed using 2,7-dichlorodihydrofluorescein diacetate assay and enzyme-linked-immunosorbent serologic assay against glutathione peroxidase and malondialdehyde. In addition, cellular alkaline phosphatase activity was executed by Alizarin Red S staining. Western blot assay was conducted to determine the expression levels of osteogenic-related markers, including type I collagen, osteopontin, runt-related transcription factor 2, and the 5' adenosine monophosphate-activated protein kinase (AMPK) signaling pathways related proteins. The key finding was that pterostilbene could attenuate the H2O2-induced cellular apoptosis and oxidative stress. Pterostilbene also promoted osteogenic differentiation in H2O2-treated MC3T3-E1 cells through activation of the AMPK pathway. In conclusion, pterostilbene blocked the H2O2-induced MC3T3-E1 cells dysfunction, indicating its potential to be a promising medication for treating osteoporosis.
Magnoflorine promotes Huh-7 cell apoptosis and autophagy by regulating PI3K/Akt/mTOR pathway
Authors: Xu Jifan , Du Bo , Liu Yunfeng , Tao Chonglin
Published: February 2022

Hepatoma is a malignant tumor with high rates of heterogeneity, metastasis, and mortality. Currently, there is no effective treatment available for hepatoma. In order to treat advanced hepatoma in a better manner, new and more effective therapeutic targets still need to be developed. Magnoflorine (MGN) is a quaternary ammonium alkaloid with a variety of therapeutic properties. MGN inhibited the proliferation of lung cancer, breast cancer, glioma, and rhabdomyosarcoma cells, induced apoptosis, and blocked cell cycle. However, its possible effects on the progression of hepatoma are still indefinite. In this study, the effects of MGN on the progression of hepatoma in vitro and the underlying mechanisms were determined. MGN suppressed the proliferation, induced the autophagy, and stimulated the apoptosis of human hepatoma Huh-7 cells. Mechanically, MGN could regulate PI3K/AKT/mTOR pathway, which therefore affects the progression of hepatoma in vitro. Taken together, MGN affected Huh-7 cell proliferation, autophagy, and apoptosis, and might act as a promising therapeutic drug for treating hepatoma.

Authors: Mesa-Pedrazas Ángela , Duque-Calvache Ricardo
Published: February 2022

El espacio público es un concepto utilizado de manera cotidiana, y frecuente en el discurso institucional; sin embargo, menos son las veces que se presta atención a su propia conceptualización. Además, los procesos de transformación urbana, y la velocidad de estos, hacen del espacio público una realidad cambiante, lo que complejiza aún más su definición. En el presente artículo se reflexiona sobre las distintas corrientes seguidas en la literatura académica para definir qué es el espacio público, cuáles son sus principales dimensiones, y qué procesos de cambio enfrenta en la actualidad, con el objetivo de aportar una definición propia de espacio público según estas características y dimensiones principales.

The Right to a Fair Trial Under Article 6 ECHR During the Covid-19 Pandemic:
Authors: Paduch Andrzej
Published: February 2022

Purpose: The aim of the study is to analyse the possibility of modifying procedural law in the context of the legislative measures taken in connection with the COVID-19 pandemic on the example of the Polish administrative judiciary system.Design/Methodology/Approach: The study employs the dogmatic-legal method, analysing the provisions of the ECHR and examples of the regulation of administrative court proceedings in Poland. The interpretation of the provisions is carried out taking into account the jurisprudence of the courts, in particular the jurisprudence of the ECtHR.Findings: The study shows that no regulation taking away the right to have the case heard in public is compliant with the ECHR. Public hearing is in fact a crucial aspect of the right to a fair trial. However, in order to mitigate the effects of a pandemic, states may introduce such solutions which – within the limits of art. 6 sec. 1 ECHR – modify the law.Academic contribution to the field: The study suggests theoretical and general solutions to the problem that arose during the COVID-19 pandemic: whether and how certain aspects of the right to a fair trial can be limited without violating its essence. The issue is analysed from the perspective of the administrative judiciary and legal solutions adopted in Poland, but the conclusions may also apply to the regulations of other European countries and even to the civil or criminal judiciary.Practical Implications: The paper presents the requirements provided in art. 6 sec. 1 ECHR in the context of restrictions of public hearing implemented to counteract the spread of the COVID-19 pandemic. It may be a basis for further studies of the problem or for assessing the solutions adopted in the member states of the Council of Europe.Originality/Value: Publications concerning modifications to procedural law in the context of the COVID-19 pandemic are not numerous in scientific literature. Due to the lack of analyses, the paper will contribute to the development of literature.
Consolidating Back Office with a Shared-Services Center:
Authors: Jovanovska Mimoza Bogdanoska , Tabakovska Nataša Blazeska , Grueski Dragan
Published: February 2022

Purpose: The paper points out a novel approach to e-Government back-office reengineering based on creating a Shared-Services Center at the sectorial level. Design/Methodology/Approach: To prove the Shared-Services Center as a proper solution for e-Government back-office reengineering, the authors used the case study of the Housing Facilities Sector in the Republic of North Macedonia. The research process follows Kettingers et al.'s framework of IT-enabled change with a holistic data-driven approach. Findings: The study indicates a complex information flow between stakeholders, an abundance of the same information and data collected from local stakeholders, and enormous citizen and institutional burden. The e-Government back-office reengineering solution for the specific case study based on creating a Shared-Services Center overcomes the problem of data redundancy, radically simplifies the information flow, and reduces citizen burden in line with the "Once-Only" principle. Practical Implications: The paper shows that by observing the network of all relevant stakeholders at the sectorial level, based on the information flow of core data, back-office problems can be identified, whereby the Shared-Services Center proves itself as a suitable solution. It may be a prerequisite for further studies on back-office process reengineering at the sectorial level. Originality/Value:  Publications concerning back-office research at the sectorial level and, as in our case, within the House Facility Sector are almost non existing in scientific literature. Considering that there is a lack of analyses based on information flow and visualization of the information-flow network at the sectorial level (before and after the reforms), this paper will add original value to scientific literature.
Career Motivation in the Process of State Regulation of Youth Employment
Authors: Stativka Natalya , Batiuk Anna
Published: February 2022

Purpose: The main objective of the study is to find new methods for the state promotion of career motivation in the process of providing youth employment.Design/Methodology/Approach: To accomplish the research objectives, a set of mutually reinforcing general scientific and special research methods was used.The basic statistical analyses of unemployment rate data according to the methodology of the International Labour Organization, while the level of registered unemployment (the national indicator of the unemployment rate in Ukraine) serves as an indicator of the State Employment Service performance.Findings: A detailed analysis of career motivation theories and the technology of servicing potentially unemployed people helped justify the feasibility of applying a communicative and psychological method in employment center specialists’ work with their clients, in particular the youth. Thus, a number of measures were identified and proposed in order to better encourage employment and increase the effectiveness of career motivation.Practical Implications: In the course of the research, the development trends in the youth labour market of Ukraine were estimated, the main causes for youth unemployment were determined, and the value orientations and characteristics of modern youth were analysed. The importance of employment services focusing on effective communication with their clients to motivate them for successful employment and self-development is substantiated. The issues of young people’s migration activity, which can have a negative effect on the economic development of the country and increase the socio-demographic risks to national security, need a detailed scientific study.Originality/Value: Currently, the science of public administration does not pay due attention to the role of public institutions in providing career motivation or to the legal consolidation of the measures that motivate productive work. A vast majority of research works on professional motivation and career development were conducted by scientists from the fields of pedagogy, psychology and social economy. These works reveal the essence of pedagogical education and the peculiarities of human psychological influence, yet fail to define the role of the state as the main social institution which should lay the basis for youth development and encouragement to employment. This renders the topic of the present study relevant.
Shoulder Arthrodesis: A New Technique
Authors: Voronkevich Igor A. , Varfolomeev Alexander  P. , Geraschenko Nikita I.
Published: February 2022

Background. The replacement of fusion by arthroplasty in terminal shoulder arthropathies has led to the emergence of cases contraindicated for revision arthroplasty. Performing fusion by traditional methods in such cases is extremely risky because of unfavorable conditions: absence of the humeral head, thinning of the metaphysis walls, and defects of the glenoid. Thus, the creation of a new shoulder fusion technique is necessary.
The study aimed to show the possibilities of a new shoulder fusion technique in treating arthroplasty complications and terminal shoulder arthropathies.
The surgical procedure includes the resection of the shoulder joint and internal fixation with a special device containing a scapular fork with four locking screws and a bone plate. The fork was put on the scapular spine from the side of its notch and was blocked by four tightening screws, which clamped the scapular spine in the fork. The bone plate fixed the diaphysis of the humerus. The fixator form set the scapulohumeral ratio for the formation of ankylosis in a functional position. Bone grafting was performed with a graft from the wing of the iliac bone according to the special technique after endoprosthesis removal or with the resected head of the humerus in case of arthrosis.
Conclusions. The developed technique can be used as a standard revision option for contraindications to shoulder arthroplasty and for any traditional indications for its fusion, such as oncological resections, consequences of open and gunshot trauma, lesions of the brachial plexus, and terminal arthropathies in persons engaged in heavy physical labor when it is impossible to change profession.
An Earthquake Simulator for New Zealand
Authors: Shaw Bruce E. , Fry Bill , Nicol Andrew , Howell Andrew , Gerstenberger Matthew
Published: February 2022

We present an earthquake simulator for New Zealand. It uses the Rate-and-State Earthquake Simulator engine based on approximations of the rate-and-state friction equations. The full set of faults considered in the most recent New Zealand national seismic hazard maps are included in the simulator. New simulator methods are introduced that allow for the inclusion and interaction between upper plate faults and a subduction interface fault below them. The simulator generates sequences of complex slip events and a catalog of finite ruptures hundreds of thousands of years in length. Results from the simulator are evaluated through statistical testing and comparison with geological and geophysical observations. These evaluations include a spatial comparison against historical earthquakes, a comparison against rates of events in the instrumental catalog, and a comparison against scaling relations. Consistency of the model with these measures is generally found, though some differences with productivity is noted, due to incomplete modeling of subducting slab features like geodetically inferred spatially dependent creep and dense faulting in Bay of Plenty faults. Significant emergent aspects of the resulting synthetic catalog are discussed. These include substantial variability over instrumental catalog timescales, clustering of large events in space and time, and spontaneous ruptures that break both the upper crustal faults and subduction interface coseismically. An online repository provides the model output, and an additional site provides python code for reproducing some of the figures in this article and tools for further model output analysis.

Published: February 2022

Generalized inversion techniques (GITs) have become popular for determining seismological parameters (e.g., source, attenuation, and site response), particularly in low-to-moderate seismicity regions. Indeed, GITs can potentially provide reliable site-response estimates when a minimum number of recordings is available, as well as valuable information about source parameters and regional attenuation characteristics. Significant advances have been made on GITs in which different approaches and hypotheses were investigated, such as the application of “nonparametric” and “parametric” inversion schemes. In this context, several scientific questions have arisen that depend on the final scope of the GITs: What is the optimal inversion strategy for a given dataset configuration? What is the impact of the different choices, assumptions, and implementations on the reliability of the results? Is it possible to quantify the associated epistemic uncertainties? Here, we have considered and compared the different approaches of GITs to improve the understanding of each for use in different applications. A methodological benchmark that includes different GIT methods and dataset configurations is set up to fulfill the objective, using a simple synthetic dataset, a French regional sparse dataset, and an Italian national dense dataset. The benchmark is developed in two phases: (1) phase I: a free phase with no common constraints; and (2) phase II: a constrained phase with unified reference conditions. Despite unifying the reference conditions in the different inversions, the variability was not reduced. Discrepancies are observed between different terms of GITs. Site responses appear to be the most robust estimates, compared to source and attenuation terms. The way that stress drops of earthquakes and quality factors for crustal attenuation are parameterized appears to lead to significant variability between different approaches. Finally, uncertainties are addressed by quantification of the inter-method variability for the different terms and parameters.
Cultures of Place
Authors:   , Jahr Rachel E. , Koltick Nicole , Nicholas Diana S.
Published: February 2022

This thesis explores the intersection of cultures, places, and ecologies and how to intentionally combine them through an integrated level of design thinking focusing on the shifting perception of urban living through permaculture practices and regenerative design techniques to augment solutions for urban density. Regenerative design practice is a process that considers cultural, economic, and green space factors as prominent design issues. The instrumentality of integrating building systems makes sustainable life practices accessible to all and adds to the wealth of both human and ecological communities. The objective of a permaculture urban lens is that it can be an agent of change in the transition to an eco-conscious world while also promoting the wellbeing of occupants of future urban landscapes. By experiencing a multi-functional space that promotes health and happiness by utilizing social and natural systems together, physical spaces can revolutionize society's current ontological stance on human culture and natural ecology. The following research outlines the mechanisms related to designing an ecologically friendly urban setting through a place-based approach influenced by the human lived experience as well as technological advancements.
The Nonidentity Problem is an Artifact of Faulty Causal Reasoning
Authors: Gildenhuys Peter
Published: February 2022

This paper argues that the nonidentity problem is really an artifact of faulty causal reasoning. In order to solve the nonidentity problem, we must determine that an agent causes a loss of happiness to another agent by means of an action that also causes the victim to exist. Woodward’s (2003) test for actual causation yields just this result. Equally crucial to solving the problem is the recognition that harms must be intentional and that intentionality is a function of norm-violation; this latter position is defended by Holton (2010). That the solution proposed is adequate is defended on the grounds that it yields intuitively correct judgments for a host of imaginary scenarios contemplated by theorists focused on determining what should count as harms.
The Anthropic Cosmological Principle: a Thematic case of Teleology and Causality in Contemporary Science
Authors: Barbosa João
Published: February 2022

The successive versions of the anthropic cosmological principle reintroduced teleology in cosmology, articulating it with two forms of mechanical causality – probabilism and determinism. According to the thematic analysis of science proposed by Gerald Holton, we can say that teleology is the opposing thema (the antithema) of mechanical causality. A return of teleology easily creates suspicions because mechanical causality dominates contemporary science, and teleology is widely considered an obsolete kind of scientific reasoning. Furthermore, in the anthropic cosmological principle, teleology has a deep anthropocentric feature. From the thematic point of view, the teleology of the anthropic cosmological principle is in counter-cycle. However, the cyclical functioning of themata suggests that perhaps teleology is not forever condemned to the past or to a marginal presence in scientific thought.

Consideraciones sobre la reforma de la legislación civil en materia de discapacidad: de la incapacitación al apoyo
Authors: Sánchez Hernández Ángel
Published: February 2022

La reforma de la legislación civil para el apoyo a las personas con discapacidad en el ejercicio de su capacidad jurídica (Ley 8/2021, de 2 de junio), busca la adaptación a la Convención de Nueva York de 2006 para facilitar la toma de las propias decisiones de esas personas mediante un modelo de apoyos. No se trata de que el tercero que apoya sustituya a la persona con discapacidad intelectual, sino de que aquel ponga a disposición de ésta los apoyos precisos para que pueda tomar sus propias decisiones, recuperando su protagonismo en la toma de decisiones que le afectan, como protagonista activo en el desarrollo de su proyecto vital. La intervención del tercero que apoya no es para sustituir a la persona con discapacidad intelectual en la toma de decisiones, sino que se dirige a ayudarla a decidir para que pueda desarrollar su libertad y su autonomía personal.
Progress toward Resilient Infrastructures: Are we falling behind the pace of events and changing threats?
Authors: Woods David D. , Alderson David L.
Published: February 2022

The current strategy for achieving resilient infrastructures is making progress too slowly to keep up with the pace of change as evidenced by a continuing stream of “shock” events. How do we better anticipate changing threats and recognize emerging new vulnerabilities in an increasingly interconnected world? We are facing a Strategic Agility Gap that requires us to revise our current perspective and processes if we are to make meaningful progress.
A Functional All‐Hazard Approach to Critical Infrastructure Dependency Analysis
Authors: Hruska Ryan , McGillivary Kent , Edsall Robert
Published: February 2022

The critical infrastructures protection landscape is a vast and varied pattern of independent, but interconnected infrastructure systems that are essential to the function of our modern society. The U.S. policy on critical infrastructure protection has been continually evolving since the “President's Commission on Critical Infrastructure Protection” was published in 1997. In response to these policies, federal, state, and local governments, along with research institutions, have invested a substantial amount of time and effort into identifying and analyzing critical infrastructure, their functions, and dependencies/interdependencies to better understand their vulnerabilities. To date, the ability to assess vulnerabilities, resiliency, and priorities for protecting interdependent critical infrastructure systems from an all‐hazards perspective remains a difficult problem. In this paper we introduce the All‐Hazards Analysis (AHA) methodology, which provides an integrated functional basis across infrastructure systems, through the implementation of a common language and a scalable level of decomposition to effectively evaluate the resilience of interconnected infrastructure systems. AHA models infrastructure systems as directed multidimensional graphs, which enable the evaluation of cross‐sector interdependencies prior to, during, and after disruptive events. Finally, and by design, AHA enables the cross linking of data taxonomies to enable more effective data sharing, such as the National Critical Functions (NCF) and Infrastructure Data Taxonomy (IDT).

Ultrasound-Guided Peripherally Inserted Central Catheter Placement in Extremely Low Birth Weight Neonates
Authors: Fridolfsson Pernilla Eva Johanna
Published: February 2022

Extremely low birth weight (ELBW), <1,000 g, neonates require central venous access for their growth, development, and survival. Peripherally inserted central catheters (PICCs) provide such access and reduce the risks associated with other types of central venous catheters. While the use of ultrasound (US) to guide PICC placement further reduces these risks, this technology has not been integrated into neonatal practice. The purpose of this case study is to describe US-guided PICC placement in 2 ELBW neonates. PICCs were placed in 2 patients weighing 505 g and 800 g, respectively, utilizing US guidance where the practitioner was unable to identify veins using traditional methods (e.g., palpation, landmarks, transillumination, or infrared device). PICC placement utilizing US guidance in ELBW neonates is a safe and effective technique that improves outcomes, prevents complications, and promotes vessel preservation in this vulnerable population. It is essential that this technique is integrated into neonatal practice.

What is the Relationship between the Four Dimensions of the Balanced Scorecard and Organization Performance of Ghanaian Public Universities?
Authors: Nyukorong Remy
Published: February 2022

The Balanced Scorecard (BSC) is one of the best-known strategic planning and evaluation tools that uses both monetary and non-monetary data. This paper focuses on empirically testing whether the four dimensions of the BSC predicts organizational performance of Ghanaian public universities. The study adopted a cross-sectional, descriptive survey design and the primary sources of data was gathered through hand-administered structured questionnaires from both academic and administrative staff of 10 accredited public universities in Ghana. The study also employed structural Equation Model (SEM) with SmartPLS to analyze 134 samples. Results of the boostrapping method for the structural model and the t-values of the four dimensions of the BSC were significantly and statistically different from each other, but all showed a positive relation on perceived organizational performance. The results showed that non-financial measures have better outcomes for employees’ performances which corroborates the central proposition of the Balanced Scorecard. It is recommended that public universities that want to maintain and improve organizational performance must pay attention to the customers’ perspective by providing relevant and high-quality education that acquaints students with knowledge and transferable basic skills and also identify opportunities for special initiatives, collaborative partnerships, and accountability to constituents.

La pandemia sigue afectando al componente social de las personas, debido a las restricciones, los distanciamientos y los confinamientos, provocando cambios drásticos en la forma de convivir con el entorno y en las interrelaciones laborales. Con estas perspectivas surge la necesidad de conocer y evaluar los entornos laborales durante la pandemia, con el objetivo de conocer las particularidades y conflictos que se desarrollan en esta nueva relación laboral. La educación se ha adaptado a la modalidad de teletrabajo para los docentes y de teleeducación para los estudiantes, donde ambos grupos humanos han tenido que ajustar los entornos de su residencia para desarrollar las diferentes actividades. La presente investigación tiene como propósito analizar el clima laboral en el Instituto Superior Tecnológico Juan Bautista Aguirre de la ciudad de Daule (Ecuador) durante la pandemia de covid-19; para ello se realizó una encuesta a 61 docentes voluntarios, en la cual se abordaron las dimensiones de: sentido de pertenencia, relaciones entre compañeros, satisfacción, eficacia y eficiencia, liderazgo, reconocimiento y oportunidades de desarrollo e innovación. Adicionalmente se realizó una entrevista a la máxima autoridad de la institución para conocer las perspectivas gerenciales relacionadas al clima laboral. De manera general se determinó el promedio porcentual de las dimensiones, donde el 73% de la valoración fue positiva, mientras que el 27% fue negativa.

La présente étude s’est intéressée à la question du mode d’accès à la terre par les femmes du Nord, et celles Sud de la Côte d’Ivoire. Elle se propose de comparer les déterminants socioculturels de l’accessibilité différentiée à la terre chez les femmes Sénoufo et Akyé. La population ciblée pour l’étude menée entre Avril 2021 et Juin 2021 est constituée d’autorités coutumières, des leaders communautaires et des femmes résidentes ou non, et membres ou non des coopératives agricoles. La démarche sur laquelle s’est appuyée cette étude est de type qualitatif orientée selon la méthode comparative et conduite à l’aide d’entretien individuel, de focus groups et d’observation participante. La théorie comparative a été convoquée pour mieux faire la comparaison entre ces deux entités (femme du Nord et femme du Sud) et apporter un meilleur éclairage sur la question de leur accès à la terre. L’analyse de la question de l’accessibilité de la terre a montré que les femmes du Sud de la Côte d’Ivoire accèdent de plus en plus à la terre car les normes, règles et valeurs de cette société ont connu des mutations tendant à intégrer la femme dans le partage de la terre même si cela ne se fait pas de façon équitable entre l’homme et la femme. Chez les femmes du Nord de la Côte d’Ivoire, l’accès définitif à la terre est quasiment impossible à cause de la rigidité des valeurs, normes et règles qui régulent cette société.

 

This study looked at the question of how women in the north and south of Côte d'Ivoire access land. It compares the socio-cultural determinants of differential access to land among Senoufo and Akye women. The target population is made up of the customary authorities, community leaders, and women who may or may not be residents or members of agricultural cooperatives. The study was conducted from April to June. The approach of this study was qualitative and comparative, using individual interviews, focus groups and participant observation. The comparative theory was used to better compare these two entities (women from the North and women from the South) and to shed more light on the issue of their access to land. The analysis of the issue of access to land showed that women in the south of Côte d'Ivoire are gaining access to land because the norms, rules and values of this society have changed to include women in the sharing of land, even if this is not done in an equitable manner between men and women. Among women in the north of Côte d'Ivoire, definitive access to land is almost impossible because of the rigidity of the values, norms and rules that regulate this society.
Sustaining Water Systems in Rural and Small Towns in Ghana: The Role of Traditional Authorities in the Krachi West District

The sustainability of water systems in rural communities and small towns in Ghana has been a major challenge that has engaged the attention of government, Non-governmental Organisations, and academics. There have been several attempts at developing models that will ensure the sustainability of water systems in Ghana. This study examined the role of traditional authorities in the management of water systems in rural communities and small towns in the Krachi West District in the Oti Region of Ghana. Using a qualitative research design, the study purposely selected and interviewed 69 respondents. The study revealed that traditional authorities play critical roles in ensuring the sustainable management of water systems in rural communities and small towns in Ghana. It also revealed that respondents want a community management model that has traditional authorities as members of an official advisory board to the Water and Sanitation Management Teams (WSMTs). It further revealed that the traditional authorities and the WSMTs have a cordial working relationship. The study, therefore, recommends that traditional authorities should officially be recognised and their roles spelled out in the community management model of water systems in Ghana.

Ethanol has the potential of being an abundant biofuel considering the raw materials and indigenous technology available. Due to its oxidation tendency, higher energy density, nontoxic and environmental affability, several studies have confirmed and emphasized ethanol's choice and adaptability for usage in fuel cells. This paper aimed at parametric simulation and exergy analysis of a 30W ethanol fuel cell using a theoretical approach. The simulation considers 1atm and 65oC operating conditions while making empirically significant assumptions about layer thicknesses and other parameters. Fixed and standard parameters from the literature were applied in the mathematical expressions and models that described the energy, power generation, over-potentials, and the efficiencies inherent in the simulation. From the simulation, voltage loss due to transport contributed about 80% of the 0.1211 V while total over-potential culminated to the 3.633W irreversible power. The exergy analysis of the simulated 95% Direct Ethanol Fuel Cell (DEFC) gave 89% cell efficiency for the generation of 3,050 kJ energy, 33.80 W ideal power, and 30.28W useful power in a 90 seconds operation at a 1.1267V potential.

La présente étude a pour objectif général de démontrer les effets néfastes de l’extraction aurifère artisanale sur l’environnement de la zone phytogéographique de Kanoroba, plus spécifiquement, les effets néfastes de cette exploitation sur la richesse, la maturité et la diversité des ressources floristiques et les risques sur les activités des agents du poste forestier de Kanoroba. La démarche méthodologique utilisée tourne autour de trois axes principaux que sont : (i) la recherche documentaire, elle a permis de parcourir plusieurs travaux de recherches de spécialistes en la matière ; (ii) la collecte des données sur le terrain qui a consisté à inventorier les espèces floristique en vue de ressortir la richesse et la diversité floristique de la zone d’étude et l’impact de l’activité d’orpaillage sur celle-ci ; (iii) enfin le traitement des données a permis d’analyser et d’interpréter les données de terrain. La richesse et la diversité floristique de la zone d’étude sont composées de 24 familles, 59 genres et 72 espèces dont les familles des Caesalpinaceae et des Combretaceae sont les plus abondantes. L’orpaillage clandestin a affecté plus les espèces Afzelia africana et Pterocarpus erinaceus (bois de vène) qui sont sur la liste rouge de l’UICN. Les essences d’avenir avec 61 % de taux d’impact suivi des essences de régénération avec 38 % et enfin 1 % des essences de diamètres exploitables sont impactées par ce phénomène d’orpaillage clandestin.
El socialismo en su lugar. La «organización social» de la nación y los orígenes intersociales del primer socialismo mexicano hacia 1850
Authors: González Matías X.
Published: February 2022

El artículo tiene como objetivo problematizar las hipótesis que han estructurado el estudio del mundo del trabajo en México a mediados del siglo XIX y su relación con el lenguaje político de la nación, en particular el liberal. La complicada hipótesis de la «imposible recepción» del socialismo en el mundo del trabajo mexicano decimonónico será el punto de partida para la elaboración de un entrecruce de la historiografía del mundo del trabajo mexicano, con la historia conceptual de las últimas décadas. A través de una discusión con la propuesta del «desliz de la ciudadanía», se buscará profundizar el surco histórico trazado por los conceptos de nación que interponen la visión hegemónica respaldada en el lenguaje de nacionalidad estatal de mediados de siglo XIX. En efecto, en la formación de un «lenguaje del trabajo» mexicano ocurrieron otros deslices del lenguaje de la nación, que la desencastran de una visión homogénea. Al ser producto de una interacción que constituyó un «medio intersocial», en el que se comunicaban el lenguaje del trabajo mexicano y el socialismo francés, es también condición fundamental para entender la dimensión híbrida moderna de la nación mexicana hacia 1850.
