Network Traffic Prediction Incorporating Prior Knowledge for an Intelligent Network
Authors: Pan Chengsheng , Wang Yuyue , Shi Huaifeng , Shi Jianfeng , Cai Ren
Published: March 2022

Network traffic prediction is an important tool for the management and control of IoT, and timely and accurate traffic prediction models play a crucial role in improving the IoT service quality. The degree of burstiness in intelligent network traffic is high, which creates problems for prediction. To address the problem faced by traditional statistical models, which cannot effectively extract traffic features when dealing with inadequate sample data, in addition to the poor interpretability of deep models, this paper proposes a prediction model (fusion prior knowledge network) that incorporates prior knowledge into the neural network training process. The model takes the self-similarity of network traffic as a priori knowledge, incorporates it into the gating mechanism of the long short-term memory neural network, and combines a one-dimensional convolutional neural network with an attention mechanism to extract the temporal features of the traffic sequence. The experiments show that the model can better recover the characteristics of the original data. Compared with the traditional prediction model, the proposed model can better describe the trend of network traffic. In addition, the model produces an interpretable prediction result with an absolute correction factor of 76.4%, which is at least 10% better than the traditional statistical model.

Published: March 2022

Flavanols are a class of polyphenols that have become the focus of much research because of their medicinal properties. For this paper, a new method to determine polyphenols in nutraceutical samples was developed, based on solid-liquid extraction and further analysis by liquid chromatography. Analytes were recovered by ultrasound-assisted extraction, using a mixture of methanol/water/hydrochloric acid (70:29:1, v:v:v) as the solvent. Reversed-phase high-performance liquid chromatography with ultraviolet/visible (HPLC-UV/Vis) and fluorescence detection (HPLC-FLD) were developed to determine the content of the principal flavanols. The HPLC-FLD method showed better selectivity and sensitivity, so it was selected for further studies. The analytical parameters established with FLD were satisfactory in terms of linearity (R2 ≥ 0.993), repeatability (RSD% ≥ 2.2), and limits of detection of 0.1 mg L−1 or below. The nutraceutical samples were analyzed by HPLC-FLD to determine the compositional profiles of flavanols, then they were subsequently treated using chemometric methods, such as principal component analysis (PCA). Results showed that the study of compositional profiles from the selected flavanols was sufficient for description and discrimination purposes. The cranberry samples were the richest in flavanols, procyanidin A2 being the principal flavanol, and artichoke samples the least rich.

Authors: Kuo Kuo-Cheng , Yu Hsiao-Yun , Lu Wen-Min , Le Thu-Thao
Published: March 2022

This study employs the two-stage dynamic data envelopment analysis model to examine sustainability and corporate performances of the 29 largest multinational enterprises in the transport manufacturing industry from 2015 to 2019. The results show that, on average, sustainability has a positive relation to corporate performance and sustainability performance is better than corporate performance for all multinational enterprises (MNEs). In addition, we also found that corporate social responsibility (CSR) acts as a moderator in the relationship between sustainability and corporate performances. Overall, the American group leads the others in sustainability performance, followed by Asia and Europe. On the other hand, Europe has the highest score in terms of corporate performance. In terms of size, the results show that it is positively related to corporate performance. In contrast, leverage has a negative relationship with corporate performance. The findings of this research can assist inefficient MNEs in identifying areas for advancement by learning from their peers and provide perspective and insights into the plans for MNEs’ strategies and decisions in the future.

Published: March 2022

LTC and socio-economic deprivation of families are two relevant issues in international debate. The economic or time investment made by families in caregiving has an impact on the socio-economic status of family members in terms of economic means and social inclusion. This study analyzes the practices that are supported by home LTC, examining their characteristics, identifying their strengths, weaknesses, drivers, and barriers, as well as identifying social innovation aspects. The study provides a qualitative interpretative comparison of 22 practices from eight countries, representing the four LTC care models existing in Europe. Cross-studies aid in the development of sustainable policies. The study highlights the differences and similarities between selected practices. The results indicate the effectiveness of integrative and coordination strategies at the macro, meso, and micro levels for the development of supportive policies for family members with burdens of care. Nevertheless, the results underline the lack of a genuine focus on families’ socio-economic support for providing care. The partial support provided by compensatory cash benefits or unpaid care leave schemes partially addresses the difficulties of familial burden of care. The study recommends that fair economic compensation and social security benefits be incorporated into innovative and sustainable strategies for supporting caregiving in LTC and welfare schemes.

Published: March 2022

Despite the existence of a wide range of literature on indicators of disaster resilience in various geographical contexts that have been developed by different agencies and academia, not much has been done to include the insights of practitioners at the local level. This paper seeks to address the lack of practitioner insight and perspective by proposing a mixed methodology in developing composite indicators for the resilience of an island community to disasters. We used a combination of participatory approaches, such as semi-structured interviews with key informants, the web-based Delphi method, and expert interviews through a case study site in the Philippines—the Batanes island province. Principal Component Analysis (PCA) was utilized to analyse the data from web-Delphi, and the results from the content analysis of the interviews were used to support these findings. From a broad list of 144 indicators, the process identified 22 composite indicators for assessing the disaster resilience of an island community. We conclude that the development of new approaches for assessing disaster resilience of island communities is a positive step towards a better understanding and operationalization of the concept of resilience. The process followed in this paper is a significant milestone in developing new approaches to answer the question of what makes an island community resilient to disasters.

Authors: Choi Jungseok , Kim Woohyoung , Choi Seokkyu
Published: March 2022

The purpose of this study is to analyze the economic ripple effects caused by the supply-side reforms on China’s steel industry. To this end, using the 2012 and the 2017 China Input–Output Tables, this study analyzes the economic ripple effect of the Chinese steel industry caused by its supply-side reform. In this study, the influence coefficients (rear-linked effect) and the sensitivity coefficients (forward-linked effect), conceptualized by Leontief, are used as research tools to analyze the ripple effects of the Chinese steel industry. The analysis results are as follows. First, the fact that 2012 ranked high in professional equipment and meter manufacturing shows that the Chinese government’s supply-side reforms are effective and creating the required shift from traditional manufacturing to qualitative growth. Second, in terms of the sensitivity coefficient, in 2012, most of the top industries contributed significantly to the development of the Chinese economy. The originality of this study is as follows. The input production analysis used in this paper is a methodology mainly used in the steel, coal, automobile, and petrochemical industries, which clearly distinguishes the front and rear industries. Additionally, this study is a novel attempt at comparative research on the Chinese steel industry between 2012 and 2017.

Published: March 2022

The aim of this study was to examine the effects of a multicomponent exercise training program on motor function and biochemical markers in patients with Alzheimer’s-type dementia. Twenty patients with Alzheimer disease, divided into the intervention group (IG; aged 84 ± 3.1 years) and the control group (CG; aged 86 ± 2.6 years) were included in this study. The intervention group was enrolled into an exercise training program for three months (two sessions of 60 min per week). The CG was instructed to follow their daily rhythm of life (e.g., rest, reading) without a physical training program. After 3 months of participation in a multicomponent exercise program, gait speed, balance and walking parameters were all improved in the intervention group as measured with the Berg Balance Scale, the Tinetti test, the 6-min walking test and the timed up and go test (p < 0.05 for all; percentage range of improvements: 3.17% to 53.40%), except the walking while talking test, and biochemical parameters were not affected (p > 0.05). Our results demonstrate that exercise improves postural control, aerobic capacity and mobility functions in patients with Alzheimer disease. Physical exercise is a safe and effective method for treating physical disorders in patients with Alzheimer’s disease and can easily be integrated in various programs for the management of Alzheimer disease.
Looking for Common Ground: Marine Living Resource Development in Alaska and Northern Norway in the Context of the Blue Economy
Authors: Tsiouvalas Apostolos , Stoeva Gergana , Raspotnik Andreas
Published: March 2022

Although the concept of the blue economy was created by the Small Island Developing States, its relevance extends to any coastal region around the globe, making the engagement of both state and corporate actors imperative. At the core of the blue economy framework stands the incorporation of ocean values and services into economic modeling and governance. Sustainable fisheries and aquaculture are thus significant in this endeavor, particularly for Arctic nations, the economies of which are predominantly based on seafood production. Yet, while focus is increasingly placed on sustainability and blue economy models among Arctic states, the need for structured transnational collaboration is not always acknowledged. In that respect, this article aims to articulate a comparative study of the status quo, challenges, and opportunities of fisheries and aquaculture in Alaska and northern Norway and seeks to explore potentials for cross-sectoral synergies between the two regions in the context of the blue economy.
Dynamic Behavior of the Transition Zone of an Integral Abutment Bridge

Published: March 2022

Weaker sections of a railway track, such as the approach sections, are prone to differential settlement under the action of repeated train loads. The railway tracks degrade more quickly at a critical section adjacent to a traditional rail bridge because of progressive deterioration. Opting for an integral abutment instead of a traditional bridge is gaining importance due to its improved performance in terms of track stiffness and reduced settlement. It is essential to understand such issues with the appropriate methodologies. This study investigates the behavior of an integral abutment bridge with the transition zone subjected to train loading. Generally, the transition zone is a two-part wedge section consisting of unbound granular material and cement bound mixture. A field monitored traditional abutment bridge system is used to validate the developed two-dimensional Finite Element (FE) model. The model is further developed to simulate the dynamic behavior of the transition zone against the varying speeds of the train. The parametric study is performed on the transition zone by varying its geometric configurations and considering different materials for the backfill. The results indicate that the trapezoidal approach slab influences the track displacement significantly. The transition zone thickness and material properties of the backfill have a greater effect on the overall track response. Based on the results, the stable transition zones are identified to cater to the gradual stiffness variation during train–track interaction.

The aim of the paper is to systematically analyse the effects of the online environment on customers’ behaviour in order to offer a first, comprehensive state-of-the-art of the research on this topic. By analyzing a final sample of 105 papers, 4 themes have been identified, according to the theoretical lenses adopted by scholars. Results show that the traditional stimuli–organism–responses approach (also known as S–O–R) is the most frequently applicable conceptual framework for the analysis of the effects of the online setting, and worth mentioning are the modifications to the original S–O–R model proposed by scholars, which allow considering the specificities of the online environment.
A Storytelling Methodology to Facilitate User-Centered Co-Ideation between Scientists and Designers
Authors: Talgorn Elise , Hendriks Monique , Geurts Luc , Bakker Conny
Published: March 2022

Successful implementation of sustainable innovation requires strong collaborative ecosystems. In particular, collaboration between scientific and people-centered expertise (e.g., designers) is essential to bring technical innovation through contextualized, meaningful and attractive experiences. However, in practice, these types of expertise are siloed and struggle to communicate and think together. We present a creative design method based on participatory story building to support collaborative user-centered ideation between technology scientists and designers. The core of the method is a new story creation model, the three-tension framework, that facilitates the exploration of users’ experiences and needs during ideation. To evaluate the method’s effectiveness, we conducted open-ended interviews with participants. We found that the method facilitates the expression of different perspectives and outside-the-box creative thinking. An originality and strength of our method is that it favors the discovery of new issues and pain points—rather than only solutions. This, combined with idea enrichment by multidisciplinary expertise, contributes to generating ideas in a broader range of application areas than usual. Our results indicate that participatory storytelling has the potential to facilitate multidisciplinary collaboration and to bring user-centered thinking to non-design stakeholders in order to envision user needs in future scenarios and new ecosystems.

Published: March 2022

Conflict in human relations is unavoidable; therefore, it can occur in construction projects that are full of many human relationships. These conflicts can lead to claims if interlocutors do not agree. The main result of the claims is the delay and overrun of costs in construction projects. Additionally, poor management of claims affects the success of construction projects and their budget and schedule. Moreover, controlling claims ensures the successful completion of construction projects and minimizes delays and disputes. This study sought to improve the project performance by ranking the causes of claims and examining their impacts on Key Performance Indicators (KPI) using the combined AHP-TOPSIS (Analytic Hierarchy Process-Technique for Order of Preference by Similarity to Ideal Solution) method. Given that construction projects are constantly evolving and becoming more complex and have many linear and nonlinear relationships and structures, these projects can be considered as a kind of system dynamics. The system dynamics have been used for nearly four decades to analyze and improve the performance of construction projects. This study attempted to provide a model with a system dynamics approach to predict the performance of construction projects based on the reasons for the claim. In this model, the most important performance indicators, interactions between them, and the relationship of these indicators with the reasons for claiming were simulated. The results showed that delays are the most important reasons for making claims, and they have a great impact on the KPIs such as scheduling, sustainability, customer satisfaction, quality, and team satisfaction, respectively. In the modeling and simulation discussion in this study, the proposed model simulated the dependencies between the KPIs of construction projects and their changes over time and provides a better understanding of how performance indicators interact with each other. Additionally, it can be used as a basis for simulating different management policies to find the best solution to prevent and correct the negative effects of poor performance.

Published: March 2022

In this paper, we develop statistical inference of competing risks samples which are collected under a joint Type-II censoring scheme of products with Weibull lifetime distributions. These inferences are drawn from two independent fatal risks and come from two different lines of production with the same facility. The model parameters and the parameters of life (reliability and hazard rate functions) are estimated using maximum likelihood (ML), bootstrap and Bayes methods. Additionally, we constructed asymptotic ML confidence intervals, bootstrap confidence intervals and Bayes credible intervals. Furthermore, the theoretical results are assessed and compared through Monte Carlo simulations. Finally, one real data set is analyzed under the proposed model for illustrative purpose.

Published: March 2022

International need for water quality is placing a high demand on separation technology to develop advanced oxidative processes for polyethersulfone (PES) membranes to help improve water purification. Therefore, VUV photo-oxidation with a low pressure Ar plasma was studied to improve the hydrophilicity of PES by flowing oxygen over the surface during treatment. X-ray photoelectron spectroscopy (XPS) detected a decrease in the C at% (4.4 ± 1.7 at%), increase in O at% (3.7 ± 1.0 at%), and a constant S at% (5.4 ± 0.2 at%). Curve fitting of the XPS spectra showed a decrease in sp2 C-C aromatic group bonding, and an increase in C-O, C-S, O=C-OH, sulphonate (-SO3) and sulphate (-SO4) functional groups with treatment time. The water contact angle decreased from 71.9° for untreated PES down to a saturation level of 41.9° with treatment. Since scanning electron microscopy (SEM) showed no major changes in surface roughness, the increase in hydrophilicity was mainly due to oxidation of the surface. Washing the VUV photo-oxidized PES samples with water or ethanol increased the water contact angle saturation level up to 66° indicating the formation of a weak boundary layer.

Published: March 2022

Background: In this study, the clinical response to treatment with intravenous lipid emulsion (ILE) for nine cats intoxicated with permethrin has been described. Methods: The enrolled cats showed acute onset of seizures, tremors and hypersalivation that were partially controlled with the administration of benzodiazepines and intravenous fluid therapy. Due to worsening clinical signs, intravenous lipid emulsion (intralipid 20%; 1.5 mL/kg in bolus, followed by 15 mL/kg for 1 h in infusion) was administered. Results: After ILE treatment, all cats recovered rapidly and were discharged within 24–54 h. Intravenous lipid emulsion appears to be a relatively safe and inexpensive alternative, with a short hospitalization time. Conclusions: Intravenous lipid emulsion could be an interesting therapeutic option in emergency and critical care protocols for permethrin toxicosis.

The H9N2 subtype avian influenza viruses (AIVs) have been circulating in China for more than 20 years, attracting more and more attention due to the potential threat of them. At present, vaccination is a common prevention and control strategy in poultry farms, but as virus antigenicity evolves, the immune protection efficiency of vaccines has constantly been challenged. In this study, we downloaded the hemagglutinin (HA) protein sequences of the H9N2 subtype AIVs from 1994 to 2019 in China—with a total of 5138 sequences. The above sequences were analyzed in terms of time and space, and it was found that h9.4.2.5 was the most popular in various regions of China. Furthermore, the prevalence of H9N2 subtype AIVs in China around 2006 was different. The domestic epidemic branch was relatively diversified from 1994 to 2006. After 2006, the epidemic branch each year was h9.4.2.5. We compared the sequences around 2006 as a whole and screened out 15 different amino acid positions. Based on the HA protein of A/chicken/Guangxi/55/2005 (GX55), the abovementioned amino acid mutations were completed. According to the 12-plasmid reverse genetic system, the rescue of the mutant virus was completed using A/PuertoRico/8/1934 (H1N1) (PR8) as the backbone. The cross hemagglutination inhibition test showed that these mutant sites could transform the parental strain from the old to the new antigenic region. Animal experiments indicated that the mutant virus provided significant protection against the virus from the new antigenic region. This study revealed the antigenic evolution of H9N2 subtype AIVs in China. At the same time, it provided an experimental basis for the development of new vaccines.

Effect of Fault Extension Relevant to Unconformity on Hydrothermal Fluid Flow, Mass Transport, and Uranium Deposition
Authors: Lin Hua , Xu Xu , Yang Jianwen
Published: March 2022

In this study, a conceptual model is developed based on common features of typical unconformity-related uranium deposits in the Athabasca Basin, Canada. Three reactive flow modeling scenarios are designed to address the effect of fault extension on the formation of uranium deposits. Our results indicate that the location of the fault zone relevant to the unconformity is crucial to the fluid circulation in both the sandstone layer and the basement unit, the temperature distribution, the transport of aqueous components, and the uranium deposition. In particular, this research reveals that the circulating pattern of the basement brine is critical for the ore genesis. The reducing basal brine is capable of carrying aqueous uranium from depth to react with the shallow oxidizing fluid, being percolated to the basement from the overlain sandstone layer, for uranium precipitation. Scenarios 1 and 2, in which the fault zone is mainly in the basement, are in favor of focusing ore-forming hydrothermal fluids into the footwall area in the basement, leading to the formation of uranium deposits therein. Scenario 3, in which the fault zone is mainly in the sandstone layer with a limited extension below the unconformity, is unfavorable for the focusing of fluids, and hence no significant deposits can be formed, except for some minor uranium mineralization occurring in the footwall and other areas in the basement that are spatially associated with the upwelling flow zones in the sandstone layer.
Numerical Assessment of Groundwater Flowpaths below a Streambed in Alluvial Plains Impacted by a Pumping Field
Authors: Texier Jérôme , Gonçalvès Julio , Rivière Agnès
Published: March 2022

The quality of the water from a riverbank well field is the result of the mixing ratios between the surface water and the local and regional groundwater. The mixing ratio is controlled by the complex processes involved in the surface water–groundwater interactions. In addition, the drawdown of the groundwater level greatly determines the water head differences between the river water and groundwater, as well as the field flowpath inside the alluvial plain, which subsequently impacts the water origin in the well. In common view, groundwater flows from both sides of the valley towards the river, and the groundwater divide is located at the middle of the river. Here, we studied the standard case of a river connected with an alluvial aquifer exploited by a linear pumping field on one riverbank, and we proposed to determine the physical parameters controlling the occurrence of groundwater flow below the river from one bank to the other (cross-riverbank flow). For this purpose, a 2D saturated–unsaturated flow numerical model is used to analyze the groundwater flowpath below a streambed. The alternative scenarios of surface water–groundwater interactions considered here are based on variable regional gradient conditions, pumping conditions, streambed clogging and the aquifer thickness to the river width ratio (aspect ratio). Parameters such as the aspect ratio and the properties of the clogging layer play a crucial role in the occurrence of this flow, and its magnitude increases with the aquifer thickness and the streambed clogging. We demonstrate that for an aspect ratio below 0.2, cross-riverbank flow is negligible. Conversely, when the aspect ratio exceeds 0.7, 20% of the well water comes from the other bank and can even exceed the river contribution when the aspect ratio reaches 0.95. In this situation, contaminant transfers from the opposite riverbank should not be neglected even at low clogging.
El fin del "oasis": el cambio político en el Pacífico sudamericano

Las victorias de Pedro Castillo en Perú y de Gabriel Boric en Chile han provocado que, desde algunos sectores, se considere como algo seguro la existencia de una segunda ola progresista en la región latinoamericana. Sin embargo, analizando un poco más de cerca ambos casos, esta afirmación se torna discutible. Los hechos electorales no parecen suficientes para determinar la orientación y las acciones posteriores de un gobierno. Lenin Moreno, Ollanta Humala o Juan Manuel Santos son ejemplos de que es necesario esperar algo más que pocos meses para sostener afirmaciones ideológicas rotundas. Asimismo, la relación con la izquierda bolivariana, en particular con Venezuela, y la problemática de la migración venezolana, son elementos a tomar en cuenta en el análisis

Published: March 2022

Vaccination of SARS-CoV-2 infection is an obvious and significant component of the fight against the COVID-19 pandemic. Vaccination of groups of patients with the weakened immunological response to the vaccine, such as patients with chronic liver diseases (CLD), is especially important. Due to constantly updated data, general practitioners may lose sight of the features of immunization of patients with CLD from the professional field of view. The purpose is to highlight current ideas on the immunization of patients with CLD of various etiologies, to consider possible risks of vaccination, to identify prospects for further research in this area. Conclusion. All patients with CLD, regardless of the etiology and stage of the disease, are recommended to be vaccinated against COVID-19, which reduces the risk of decompensation of both the main and concomitant chronic diseases, the onset of adverse outcomes and leads to the formation of collective immunity of the population

Objective: This study aims to analyze the effect of transformational leadership, self-efficacy, and work loyalty on organizational citizenship behavior. Research Design & Methods: This study is explanatory research using a quantitative approach. The research sample was selected based on the proportional random sampling method from employees of one of the furniture companies in Jepara with a total of 89 people. Primary data was obtained using a questionnaire that was distributed to employees directly. Statistical data analysis was performed using multiple linear regression with SPSS tool. Findings: Empirically, the results of this study accept all the hypotheses proposed, that: transformational leadership style has a significant effect on organizational citizenship behavior; self-efficacy has been proven to have a significant effect on organizational citizenship behavior; and work loyalty proved to have a significant effect on organizational citizenship behavior. Implications & Recommendations: The results of this study support previous research and contribute to a literature study that emphasizes the issue of this research in the context of a company experiencing a decline in performance so that it requires an extra employee role (OCB). Contribution & Value Added: Based on the dominant variable analysis, the company can increase the extra role of employees by increasing employee loyalty. And then loyalty can be spurred by directing employees to work in teams.

Microbial transformation is a biological process during which microorganisms transform organic molecules. Nitrofurazone is widely applied in poultry and aquaculture veterinary drugs. Without appropriate treatment, nitrofurazone residue from agriculture animal waste may have a negative impact on microorganisms. Thus, a study to enhance nitrofurazone degradation using local Aspergillus tamarii KX610719.1 was explored by optimizing the selected parameters. The specific aims of the exploration were: 1) to optimize parameters (pH, temperature and agitation speed) for nitrofurazone degradation rate, 2) to determine the nitrofurazone residue using a High-Performance Liquid Chromatography-diode array detector (HPLC-DAD), 3) to verify the optimum parameters performance in degrading nitrofurazone. Response Surface Methodology (RSM) based on Central Composite Design (CCD) was employed to analyze and optimize the effect of parameters as independent parameters on the nitrofurazone degradation rate as the response function. The interaction effects and optimum parameters were obtained using Design Expert Version 13.0 software (Stat Ease, Inc., Minneapolis, USA). The adequacy of the model test was determined using statistical analysis of variance (ANOVA) with a 95% confidence level, which demonstrated satisfactory agreement between the experimental data and the predicted model. The results demonstrate that the optimum conditions for nitrofurazone degradation rate were at the pH value (4.80), temperature (35.84 ºC) and agitation speed (121.33 rpm) with a coefficient of determination, R2 of 0.9612. Based on the verification process, the actual and predicted results was did not significantly differ (P <0.01). A. tamarii KX610719.1 showed a great ability in degrading nitrofurazone under optimum parameters.

Synthetic maize varieties present advantages in adaptability, they can be used for several planting seasons, without affecting the yield and is easier the seed production. Thus, with the main objective of knowing the yield and agronomic traits of synthetic maize varieties for the tropic, during 2013 to 2018 there was conducted an experiment in Cotaxtla and Carlos A. Carrillo in Veracruz and Huimanguillo in Tabasco state locations. The experiment was distributed in complete blocks at random design with 21 entries and three replications in plots of two rows 5m long and 62,500 pl ha-1. The agronomic traits were: Grain yield, days to tassel and silking, plant and ear aspect and sanity, lodging, bad husk cover and ear rot. From the combined analysis for yield, there was found high significant differences for Varieties (V), For environments (E), and for the interaction VxE, and a coefficient of variation of 16.20%. The Carlos A. Carrillo, Ver., location in 2016B, recorded the highest yield with 6.94 t ha-1. The best five synthetics at 0.05 of probability were: VS-536, Synthetic 2B, Synthetic 5B, Synthetic 2C and Synthetic 11C.
Poder hegemónico en las patentes: concentración del conocimiento en el Norte y exclusión de los innovadores del Sur

Los países centrales en lo general y Estados Unidos en lo particular han consolidado su posición dominante en la generación y explotación de patentes, particularmente desde la década de 1990. Esta condición es excluyente para los países periféricos, los que además de transferir recursos por el pago de licencias y regalías, lo hacen también a través de la mano de obra altamente calificada que trabaja dentro de las fronteras de los países centrales propietarios de patentes o por medio de las redes globales de colaboración virtual donde se genera la innovación, y cuyo costo de formación ha sido asimilado por los países de origen. La salida de recursos financieros, las personas altamente calificadas y los conocimientos, forman una nueva tríada de «migración sin retorno», que define el papel actual de la periferia. El propósito de este artículo es determinar la contribución de tecnólogos y científicos originarios de países distintos al de los propietarios de patentes y, al analizar en la evolución de las ganancias derivadas de la propiedad de patentes, perfilar los términos de la condición hegemónica de Estados Unidos en cuanto a la innovación y al control de la propiedad intelectual.
Honduras, una máquina expulsora de personas: ¿qué pasó antes y después de las caravanas migrantes?
Authors:   Investigador independiente, López Recinos Vladimir
Published: March 2022

El artículo describe y analiza el caso de Honduras, que de ser receptor de inmigrantes y refugiados se convirtió en uno de los países más expulsores de personas hacia Estados Unidos de América. Se abordan los distintos matices de la masiva migración hondureña que medios de comunicación e investigadores han calificado como algo novedoso y con el mote de «caravanas», pero que realmente no es un fenómeno nuevo, es algo que ha venido dándose desde mediados y finales de la década de 1990. Es posible afirmar con base en información estadística, social, histórica y hemerográfica referente a inmigración, emigración, detención, deportación, recepción y residencia, que es a partir de 1998 cuando esa corriente migratoria empieza a mostrar un carácter más compulsivo y multifacético.
La contribución del turismo a los Objetivos de Desarrollo Sostenible desde el sector hotelero en la República Argentina
Authors:   , Salessi María Lucila
Published: March 2022

El presente estudio de enfoque cuantitativo, tipo de diseño no experimental, abordaje práctico transversal y finalidad aplicada, procura contribuir al conocimiento de la gestión sostenible en el ámbito Turístico y Hotelero a través de la construcción de un instrumento para medir de manera cuantitativa la situación, el contexto y las prácticas que realizan los establecimientos hoteleros en función del cumplimiento de los Objetivos de Desarrollo Sostenible (ODS) en el año 2020. Para ello se ha diseñado y administrado un instrumento ad hoc dirigido a directivos de establecimientos hoteleros certificados por el estándar Hoteles más Verdes alcanzando un n=71. La creación y utilización de un instrumento de medición de la contribución del sector hotelero a los ODS en Argentina ha facilitado la obtención de conocimientos diagnósticos precisos sobre la situación, contexto y prácticas de la gestión sostenible en dicho ámbito. El instrumento ha demostrado confiabilidad y entre los hallazgos que permitió obtener se destaca que los directivos realizan más acciones de lo que creen en materia sostenible, lo que implica un desconocimiento del alcance del verdadero criterio de sostenibilidad, ya que la mitad desconoce cómo sus prácticas se alinean con los ODS y la Agenda 2030. El presente estudio ha revelado, asimismo, la importancia de las certificaciones y de la labor de las instituciones que se agrupan para fomentar, difundir y calificar el cumplimiento de los ODS a través de una gestión sustentable.
