A Hybrid Approach: Dynamic Diagnostic Rules for Sensor Systems in Industry 4.0 Generated by Online Hyperparameter Tuned Random Forest
Authors: Mallak Ahlam , Fathi Madjid
Published: October 2020

In this work, a hybrid component Fault Detection and Diagnosis (FDD) approach for industrial sensor systems is established and analyzed, to provide a hybrid schema that combines the advantages and eliminates the drawbacks of both model-based and data-driven methods of diagnosis. Moreover, it shines light on a new utilization of Random Forest (RF) together with model-based diagnosis, beyond its ordinary data-driven application. RF is trained and hyperparameter tuned using three-fold cross validation over a random grid of parameters using random search, to finally generate diagnostic graphs as the dynamic, data-driven part of this system. This is followed by translating those graphs into model-based rules in the form of if-else statements, SQL queries or semantic queries such as SPARQL, in order to feed the dynamic rules into a structured model essential for further diagnosis. The RF hyperparameters are consistently updated online using the newly generated sensor data to maintain the dynamicity and accuracy of the generated graphs and rules thereafter. The architecture of the proposed method is demonstrated in a comprehensive manner, and the dynamic rules extraction phase is applied using a case study on condition monitoring of a hydraulic test rig using time-series multivariate sensor readings.

Authors: Filippo Daniela De , Benayas Javier , Peña Karem , Sánchez Flor
Published: October 2020

This study analyses how Spanish universities are communicating their commitment to sustainability to society. That entailed analysing the content of their websites and their scientific papers in sustainability science and technologies and measuring the impact of such research in social media. Results obtained from bibliometric approaches and institutional document analysis attest to intensified interest in sustainability among Spanish universities in recent years. The findings revealed an increase in the number of universities using terms associated with sustainability to designate the governing bodies. The present study also uses an activity index to identify universities that devote high effort to research on sustainability and seven Spanish universities were identified with output greater than 3% of the total. Mentions in social media were observed to have grown significantly in the last 10 years, with 38% of the sustainability papers receiving such attention, compared to 21% in 2010. Publications in open access journals have had a greater impact on social media, especially on Twitter and Facebook. The analysis of university websites showed that only 30% had social media accounts and only 6% blogs specifically designed to disseminate their sustainability activities.
Recurring Patterns and Blueprints of Industrial Symbioses as Structural Units for an IT Tool
Authors: Rohde-Lütje Anna , Wohlgemuth Volker
Published: October 2020

Industrial Symbiosis (IS) deals with the set-up of advanced circular/cascading systems, in which the energy and material flows are prolonged for multiple material and energetic (re-)utilization within industrial systems. To facilitate the technology-enabling environment of IS systems, this work deals with the identification of recurring patterns in IS systems of specific IS case studies and deduction of elementary blueprints and structural units, setting an initial cornerstone to pool and synthesize existing IS knowledge and to deploy this knowledge base in an Information Technology (IT)-supported IS tool, which would remarkably advance the scope of action and development of IS systems. An explorative cross-case analysis was conducted by investigating 80 IS case studies in depth in order to illuminate recurring (key) patterns in IS systems by generalizing and abstracting IS main structures, compositions, resource exchange activities and measures. It has been shown that similar IS sectoral partnerships and resource exchanges have recurrently formed in different regions and hence, generalizable patterns can be deduced. This study identified common IS compositions, sector clusters and key/core/anchor entities and synthesized a content basis for a database of an IS resource exchange catalog based on existing/available IS information, which can be used in an IT-supported IS tool. It contains information of specific IS resource exchanges, broken down by industrial sectors, differentiating providing and receiving sectors and which respective exchanged waste flows were processed into which secondary material/product. Once this fundamental information/data base is incorporated and applied in an IT-supported IS tool, it enables the facilitated recommendation of potential IS partners and IS actions to optimize existing IS cases or to initiate IS development. Especially, first IS germ cells of (key) entities can be derived and connected to each other considering individual circumstances and (geographical) business environments.

Published: October 2020

The correlation and perception of advertising on adolescents have been shown to be a key factor in the survival of subjective emotional states. In this research, we map the affective level in relation to emotions in the context of assessing the marketing advertisement “Man on the Moon” by John Lewis company. We assess how an emotional appeal affects adolescents in various areas of the Slovak Republic, following several crucial demographic features of respondents. We examined the affective level by means of a psychodiagnostic tool in the form of a standardized tool of the scale of subjective emotional habitual well-being. To measure the emotional component of subjective well-being, we used descriptive words that expressed experienced emotions and feelings. From the collected data, we determined the frequency of positive and negative mood and verified the dependence between the variable region and emotion. We used Pearson’s chi-square test. When evaluating the data, we found dependencies between the categorical variable region and emotion. We did not find a relationship between the variable gender and emotion. The geographical division within the national market has an impact on the experience of positive and negative emotions when looking at advertising with an emotional appeal to the story.
Training New Professionals in Service Engineering: Towards a Transdisciplinary Curriculum for Sustainable Businesses
Authors: Marcos Esperanza , De Castro Valeria , Martín-Peña María-Luz , Vara Juan Manuel
Published: October 2020

The service sector provides employment for more than 70% of the active population in developed countries, in areas as varied as tourism, commerce, logistics, finances, services, and personnel, amongst others. Despite the fact that society increasingly needs more professionals who are oriented towards this sector, there are hardly any specific plans that will provide them with appropriate training. The appearance of service science, management, and engineering (SSME) has led to a significant advance as regards understanding the skills required by a service professional. It is a transdisciplinary field that integrates aspects of business management, along with information and communication technologies and engineering, and social sciences, in addition to providing the foundations for the growth of sustainable business. This paper presents a curriculum for the training of professionals in service engineering, which has been designed and taught at a Spanish public university. This curriculum, which the university created in collaboration with SSME experts and service sector companies, stands out for two reasons: the transdisciplinary approach employed, which is one of the features of this emerging and integrative knowledge discipline, and the fact that it is providing a response to the need for higher education curricula for sustainable business development. The paper describes the method followed to create the curriculum for the Bachelor’s Degree in Service Engineering, a comparative study with other related degrees, and the results of the deployment of the degree in terms of employability.

Published: October 2020

Resilience has several meanings, among them the ability to overcome difficulty and return to the state of providing service, even if the initial conditions change. Assessing resilience in an ecosystem, or any system, requires a concise methodology with standard variables and parameters. The current challenge presented by coastal areas is focused on overcoming problems related to the water supply through correct management. This paper aims to evaluate the communal coastal aquifer system with a matrix for assessing water resilience based on indicators in the Sustainable Development Goals (SDGs) in a socio-hydrological framework and the four axes of development (political, social, environmental, and cultural), to promote the development of new strategies for water sustainability. The method is based on (i) political, economic, social, environmental, and even cultural aspects involved in sustainable water management and (ii) the groundwater resilience assessment method (GRAM) design. The GRAM is used for a quasi-quantitative assessment of the resilience in a communal coastal aquifer system. This method was applied to the Manglaralto community; the results show a highly resilient groundwater system (62.33/100 points). Representatives of the community have achieved appropriate use, management, and conservation of the water resource by applying water harvesting and other technical criteria. Hence, they have avoided aquifer overexploitation and provided water to the community.

Published: October 2020

The hospitality sector is experiencing a massive transformation currently. Hotels are currently receiving considerable criticism over their practices concerning energy, environmental, as well as resource management. As a result, managerial practices in the hospitality sector have come under scrutiny. All these developments have given rise to the concept of the ‘smart’ hotel. The smart hotel concept has received considerable attention in the relevant literature in the last few years. However, the majority of this attention has either focused on the technical side (i.e., examining smart hotels from a technological standards perspective), or adopted a rather limited perspective, choosing to focus on specific managerial practices within smart hotels (i.e., environmental management). The current paper aims to address this gap in the literature through the utilization of stated preferences discrete choice modeling methodology. Through this methodology, the paper evaluates tourists’ preferences for a wider range of managerial practices and policies pertaining to smart practices in the hospitality sector. According to the empirical findings, tourists exhibit strong and negative preferences towards the automation of the service delivery process. In addition to that, respondents were very strongly opposed towards hotels without international certification standards for their operations. On the opposite side, tourists expressed very strong and positive preferences towards water management policies (particularly policies aiming to reduce and reuse water resources). Finally, respondents exhibited strong and positive preferences towards different energy-saving technologies within hotels.
The Impact of Digital Communication and PR Models on the Sustainability of Higher Education during Crises

Published: October 2020

Currently, the world is going through a pandemic, COVID-19, that affects the four pillars of organizational sustainability. At this point, institutions’ sustainability depends on how they handle crisis communication. It seems that institutions that can adapt themselves to changes regarding the usage of digital communication platforms are survivors, and even winners, of this crisis. The general belief concerning education in developing countries claims that these countries are slow in adapting to technological innovations. Being a developing country, North Cyprus has a multi-cultural environment due to the presence of international students in tertiary education. This study explores how two public and two private universities maintained sustainability in higher education during COVID-19 by discussing the public relations models (PR) that they have used regarding digital communication. This study uses a qualitative content analysis and a quantitative method. The paper asserts that the effective usage of digital communication contributes to the sustainability of universities during this crisis. The findings revealed that the posts (text/image/poster) and videos these universities share are more concentrated on either press agentry or the public information model. Yet, a two-way symmetrical model that maintains dialogue within stakeholders is practiced less than the other PR models. Hence, there is a need for the universities to listen to their stakeholders not only in face to face communication but more through digital communication platforms as well.
Influence of Wider Longitudinal Road Markings on Vehicle Speeds in Two-Lane Rural Highways
Authors: Calvo-Poyo Francisco , de Oña Juan , Garach Morcillo Laura , Navarro-Moreno José
Published: October 2020

Longitudinal road markings are a valuable aid in driving guidance. An increase in their width may influence driving and, therefore, road safety. Wider road markings generate a perception of a narrowing lane, which may induct drivers to reduce speed. The present study tries to verify if an increased width of longitudinal road markings actually helps one to drive more slowly, and consequently leads to enhanced road safety. For this purpose, three curves with reduced visibility were selected and driving speed was measured with normal and modified (wider) longitudinal road markings. The results showed a speed reduction effect of around 3.1% with wide road markings. The speed-reducing effect of wide marks was greater during weekends and with more intense traffic volume, while it was slightly attenuated by night. Finally, the calculation of some standard cases on a working day, and considering average traffic volume, gave the following speed reductions during the day and at night, respectively: for light vehicles, 2.24% and 1.96%; for heavy vehicles, 2.46% and 2.15%. In view of the results obtained, it may be said that using wide road markings can help reduce vehicle speed, thereby contributing to reduced traffic accidents and making road transport more sustainable.
Construction of Chinese Smart Water Conservancy Platform Based on the Blockchain: Technology Integration and Innovation Application
Authors: Zhang Ying , Luo Wenwen , Yu Feifei
Published: October 2020

Blockchain technology has triggered a new round of technological innovation and industrial change. Promoting the deep integration of blockchain technology and smart water conservancy has become an essential part of the digital transformation of the Chinese smart water conservancy industry. On the basis of the analysis of the framework of the smart water conservancy system and the technology infrastructure model of the blockchain, a conceptual model of a smart water conservancy information sharing platform is established. The platform has four-in-one and multicentralized participants including government departments, water conservancy enterprises, the public, and third-party maintenance, and the design of “alliance chain + private chain” dual chain smart contract. Moreover, the multidimensional scenarios of smart water conservancy innovation applications incorporating blockchain platform technology are addressed. Then, the water rights trading market is taken as an example to propose an innovative development path with consensus mechanisms, smart contracts, asymmetric encryption, and information source tracing. Although there may be some questions and challenges related to smart water conservancy and blockchain technology, this paper can provide a reference for the sustainable development of the smart water conservancy industry due to its fundamental societal contributions.
Platform and Data Co-Operatives amidst European Pandemic Citizenship
Authors: Calzada Igor
Published: October 2020

Many European pandemic citizens will likely be unemployed during the COVID-19 crisis. This article explores whether it is possible to alter existing data governance extractivist models to incentivize the emergence of platform and data co-operatives to protect European pandemic citizens’ labor and digital rights. As such, this article aims to decipher the rationale behind the proliferation of platform and data co-operatives by responding to how new forms of co-operatives using digital technologies can provide feasible socio-economic alternatives to improve post-COVID-19 working conditions for vulnerable or already empowered pandemic citizens. This article is structured as follows. First, the European “pandemic citizenship” term is described. Second, the rationale of this article is consequently presented. Third, the research question, two hypotheses, and the action research triangulation are described. The deployment of the triangulation methodology based on action research, mixed methods and social innovation reveals the main findings through (i) Delphi study results, (ii) a taxonomy for platform and data co-operative cases, and ultimately, (iii) fieldwork research conducted in Glasgow, Barcelona and Tallinn. This article concludes that co-operatives (platform-based or data-driven), stemming from the potential resilient response of European pandemic citizens, may currently portray a feasible alternative to data governance extractivist models.
The Application of Fuzzy Analytic Hierarchy Process in Sustainable Project Selection
Authors: Alyamani Rakan , Long Suzanna
Published: October 2020

The project selection process is a crucial step in sustainable development. Effective sustainable development depends on the ability to select the appropriate sustainable project to implement to ensure that the desired goals are met. Some of the most common characteristics or criteria used in evaluating sustainable projects include novelty, uncertainty, skill and experience, technology information transfer, and project cost. Prioritizing these criteria based on relative importance helps project managers and decision makers identify elements that require additional attention, better allocate resources, as well as improve the selection process when evaluating different sustainable project alternatives. The aim of this research is to use the fuzzy analytic hierarchy process (FAHP) methodology in which fuzzy numbers are utilized to realistically represent human judgment to rank the different project criteria based on relative importance and impact on sustainable projects. The results from the FAHP show that the most important criterion to consider in sustainable project selection is project cost, followed by novelty and uncertainty as the second and third most important criteria, respectively. The two least important criteria out of the total of five examined in this research were the skill and experience and technology information transfer, respectively. These results will help project managers and decision makers identify selection criteria with higher weights of importance. Given that the selection criteria chosen for this research are not limited to the evaluation of a specific type of sustainable projects or a specific location, they can be used to evaluate different types of sustainable projects in different environments and locations.
How Extra Symmetries Affect Solutions in General Relativity
Authors: Beesham Aroonkumar , Makhanya Fisokuhle
Published: October 2020

To get exact solutions to Einstein’s field equations in general relativity, one has to impose some symmetry requirements. Otherwise, the equations are too difficult to solve. However, sometimes, the imposition of too much extra symmetry can cause the problem to become somewhat trivial. As a typical example to illustrate this, the effects of conharmonic flatness are studied and applied to Friedmann–Lemaitre–Robertson–Walker spacetime. Hence, we need to impose some symmetry to make the problem tractable, but not too much so as to make it too simple.

Published: October 2020

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), responsible for the ongoing coronavirus disease (COVID-19) pandemic, is frequently shed in faeces during infection, and viral RNA has recently been detected in sewage in some countries. We have investigated the presence of SARS-CoV-2 RNA in wastewater samples from South-East England between 14th January and 12th May 2020. A novel nested RT-PCR approach targeting five different regions of the viral genome improved the sensitivity of RT-qPCR assays and generated nucleotide sequences at sites with known sequence polymorphisms among SARS-CoV-2 isolates. We were able to detect co-circulating virus variants, some specifically prevalent in England, and to identify changes in viral RNA sequences with time consistent with the recently reported increasing global dominance of Spike protein G614 pandemic variant. Low levels of viral RNA were detected in a sample from 11th February, 3 days before the first case was reported in the sewage plant catchment area. SARS-CoV-2 RNA concentration increased in March and April, and a sharp reduction was observed in May, showing the effects of lockdown measures. We conclude that viral RNA sequences found in sewage closely resemble those from clinical samples and that environmental surveillance can be used to monitor SARS-CoV-2 transmission, tracing virus variants and detecting virus importations.
Unmapped RNA Virus Diversity in Termites and Their Symbionts

Published: October 2020

Despite their ecological importance, nothing is known about the diversity and abundance of RNA viruses in termites (Termitoidae). We used a metatranscriptomics approach to determine the RNA virome structure of 50 diverse species of termite that differ in both phylogenetic position and colony composition. From these samples, we identified 67 novel RNA viruses, characterized their genomes, quantified their abundance and inferred their evolutionary history. These viruses were found within or similar to those from the Togaviridae, Iflaviridae, Polycipiviridae, Flaviviridae, Leviviridae, Narnaviridae, Mitoviridae, Lispivirdae, Phasmaviridae, Picobirnaviridae and Partitiviridae. However, all viruses identified were novel and divergent, exhibiting only 20% to 45% amino acid identity to previously identified viruses. Our analysis suggested that 17 of the viruses identified were termite-infecting, with the remainder likely associated with the termite microbiome or diet. Unclassified sobemo-like and bunya-like viruses dominated termite viromes, while most of the phylogenetic diversity was provided by the picobirna- and mitovirus-like viruses. Of note was the identification of a novel flavi-like virus most closely related to those found in marine vertebrates and invertebrates. Notably, the sampling procedure had the strongest association with virome composition, with greater RNA virome diversity in libraries prepared from whole termite bodies than those that only sampled heads.
CD163 Antibodies Inhibit PRRSV Infection via Receptor Blocking and Transcription Suppression
Authors: Xu Huiling , Liu Zehui , Zheng Suya , Han Guangwei , He Fang
Published: October 2020

CD163 has been identified as the essential receptor for Porcine reproductive and respiratory syndrome (PRRSV), a major etiologic agent of pigs. Scavenger receptor cysteine-rich domain 5–9 (SRCR5–9) in CD163 was shown to be responsible for the virus interaction. In this study, monoclonal antibodies (mAbs) 6E8 and 9A10 against SRCR5–9 were selected based on the significant activity to inhibit PRRSV infection in Porcine Alveolar Macrophage (PAMs) and Marc-145. Both mAbs are capable of blocking variable PRRSV strains in a dose-dependent manner. Meanwhile, as candidates for both prevention and therapeutics, the antibodies successfully inhibit PRRSV infection and the related NF-κB pathway either before or after virus attachment. Besides, the antibody treatment with either mAb leads to a remarkable decrease of CD163 transcription in PAMs and Marc-145. It is potentially caused by the excessive accumulation of membrane associated CD163 due to the failure in CD163 cleavage with the antibody binding. Further, conformational epitopes targeted by 6E8 and 9A10 are identified to be spanning residues 570SXDVGXV576 in SRCR5 and Q797 in SRCR7, respectively. CD163 with mutated epitopes expressed in 3D4 cells fails to support PRRSV infection while wild type CD163 recovers PRRSV infection, indicating the critical role of these residues in PRRSV invasion. These findings promote the understanding in the interaction between PRRSV and the receptor and provide novel broad antiviral strategies for PRRSV prevention and treatment via alternative mechanisms.
Shortening the Lipid A Acyl Chains of Bordetella pertussis Enables Depletion of Lipopolysaccharide Endotoxic Activity

Published: October 2020

Whooping cough, or pertussis, is an acute respiratory infectious disease caused by the Gram-negative bacterium Bordetella pertussis. Whole-cell vaccines, which were introduced in the fifties of the previous century and proved to be effective, showed considerable reactogenicity and were replaced by subunit vaccines around the turn of the century. However, there is a considerable increase in the number of cases in industrialized countries. A possible strategy to improve vaccine-induced protection is the development of new, non-toxic, whole-cell pertussis vaccines. The reactogenicity of whole-cell pertussis vaccines is, to a large extent, derived from the lipid A moiety of the lipopolysaccharides (LPS) of the bacteria. Here, we engineered B. pertussis strains with altered lipid A structures by expressing genes for the acyltransferases LpxA, LpxD, and LpxL from other bacteria resulting in altered acyl-chain length at various positions. Whole cells and extracted LPS from the strains with shorter acyl chains showed reduced or no activation of the human Toll-like receptor 4 in HEK-Blue reporter cells, whilst a longer acyl chain increased activation. Pyrogenicity studies in rabbits confirmed the in vitro assays. These findings pave the way for the development of a new generation of whole-cell pertussis vaccines with acceptable side effects.
Immunogenicity and Protective Efficacy of a Non-Living Anthrax Vaccine versus a Live Spore Vaccine with Simultaneous Penicillin-G Treatment in Cattle

Published: October 2020

Sterne live spore vaccine (SLSV) is the current veterinary anthrax vaccine of choice. Unlike the non-living anthrax vaccine (NLAV) prototype, SLSV is incompatible with concurrent antibiotics use in an anthrax outbreak scenario. The NLAV candidates used in this study include a crude recombinant protective antigen (CrPA) and a purified recombinant protective antigen (PrPA) complemented by formalin-inactivated spores and Emulsigen-D®/Alhydrogel® adjuvants. Cattle were vaccinated twice (week 0 and 3) with NLAVs plus penicillin-G (Pen-G) treatment and compared to cattle vaccinated twice with SLSV alone and with Pen-G treatment. The immunogenicity was assessed using ELISA against rPA and FIS, toxin neutralisation assay (TNA) and opsonophagocytic assay. The protection was evaluated using an in vivo passive immunisation mouse model. The anti-rPA IgG titres for NLAVs plus Pen-G and SLSV without Pen-G treatment showed a significant increase, whereas the titres for SLSV plus Pen-G were insignificant compared to pre-vaccination values. A similar trend was measured for IgM, IgG1, and IgG2 and TNA titres (NT50) showed similar trends to anti-rPA titres across all vaccine groups. The anti-FIS IgG and IgM titres increased significantly for all vaccination groups at week 3 and 5 when compared to week 0. The spore opsonising capacity increased significantly in the NLAV vaccinated groups including Pen-G treatment and the SLSV without Pen-G but much less in the SLSV group with Pen-G treatment. Passive immunization of A/J mice challenged with a lethal dose of 34F2 spores indicated significant protective capacity of antibodies raised in the SLSV and the PrPA + FIS + adjuvants vaccinated and Pen-G treated groups but not for the NLAV with the CrPA + FIS + adjuvants and the SLSV vaccinated and Pen-G treated group. Our findings indicate that the PrPA + FIS + Emulsigen-D®/Alhydrogel® vaccine candidate may provide the same level of antibody responses and protective capacity as the SLSV. Advantageously, it can be used concurrently with Penicillin-G in an outbreak situation and as prophylactic treatment in feedlots and valuable breeding stocks.

Published: October 2020

The objective of this research was to investigate the effect of the roughage-to-concentrate (R:C) ratio and the addition of live yeast (LY) on ruminal fermentation characteristics and methane (CH4) production. The experimental design was randomly allocated according to a completely randomized design in a 4 × 4 factorial arrangement. The first factor was four rations of R:C at 80:20, 60:40, 40:60, and 20:80, and the second factor was an additional four doses of Saccharomyces cerevisiae (live yeast; LY) at 0, 2.0 × 106, 4.0 × 106, and 6.0 × 106 colony-forming unit (cfu), respectively. For the in vitro method, during the incubation, the gas production was noted at 0, 1, 2, 4, 6, 8, 10, 12, 18, 24, 48, 72, and 96 h. The rumen solution mixture was collected at 0, 4, 8, 12, and 24 h of incubating after inoculation. Cumulative gas production at 96 h was highest in the R:C ratio, at 20:80, while the addition of LY improves the kinetics and accumulation of gas (p > 0.05). Maximum in vitro dry matter digestibility (IVDMD) and in vitro organic matter digestibility (IVOMD) at 24 h after incubation were achieved at the R:C ratio 20:80 and the addition of LY at 6 × 106 cfu, which were greater than the control by 13.7% and 12.4%, respectively. Ruminal pH at 8 h after incubation decreased with an increased proportion of concentrates in the diet, whereas it was lowest when the R:C ratio was at 20:80. Increasing the proportion of a concentrate diet increased total volatile fatty acid (TVFA) and propionic acid (C3), whereas the acetic acid (C2) and C2-to-C3 ratios decreased (p < 0.05). TVFA and C3 increased with the addition of LY at 6 × 106 cfu, which was greater than the control by 11.5% and 17.2%, respectively. No interaction effect was observed between the R:C ratio and LY on the CH4 concentration. The calculated ruminal CH4 production decreased with the increasing proportion of concentrates in the diet, particularly the R:C ratio at 20:80. The CH4 production for LY addition at 6 × 106 cfu was lower than the control treatment by 17.2%. Moreover, the greatest populations of bacteria, protozoa, and fungi at 8 h after incubation were found with the addition of LY at 6 × 106 cfu, which were higher than the control by 19.0%, 20.7%, and 40.4%, respectively. In conclusion, a high ratio of roughage and the concentrate and addition of LY at 6.0 × 106 cfu of the total dietary substrate could improve rumen fermentation, improve feed digestibility, and reduce the CH4 production.

Viviamo un cambiamento d’epoca che sta radicalmente trasformando sia l’identità dell’Occidente sia ponendo nuove e radicali sfide al cristianesimo chiamato ad inculturarsi di nuovo in una realtà che da esso si sta progressivamente allontanando. L’articolo in una prima parte
ricostruisce alcuni tratti salienti della postmodernità e dell’esperienza religiosa postmoderna per poi soffermarsi su alcune questioni decisive per l’annuncio credibile del vangelo. Preso atto dell’inadeguatezza di alcune rappresentazioni trasmesse di Dio, della Chiesa, e della fede, l’articolo cerca di valorizzare alcune istanze della sensibilità contem-poranea. Soprattutto insiste sulla necessità di
rimettere al centro la domanda di senso e su-perare la crisi della ragione per ritrovare per ricostruire l’alleanza tra fede e ragione ricono-scendo nel logos lo strumento per annunciare il vangelo e dialogare con le culture.

Poučak služiteljima riječi u 2 Tim 1,6-14
Authors: Grgić Miljenka
Published: October 2020

Studija proučava Pavlov poticaj Timoteju u 2 Tim 1,6-24 pod vidom praktične pouke služiteljima Riječi. Prvi dio studije (1.) analizira literarni smještaj, strukturu i retoriku odlomka u 2 Tim 1,6-24 i detektira razloge uvjerljivosti fiktivnog poticaja, te izvodi poučke za formuliranje ekshortacije služiteljima Riječi: ona treba biti smještena u
životni kontekst služitelja Riječi (1.1.) i utemeljena na detaljnoj ekspoziciji (1.2.) te uključivati kompleks spasonosnih činjenica, koje utječu na cjelokupnu osobnost služitelja Riječi (1.3.). Drugi dio studije (2.) analizira lik Timoteja u 2 Tim 1,6-14 i pokazuje da je on kao Pavlov nasljednik u jedincatoj službi dan kao model služiteljima Riječi, a ne crkvenim upraviteljima (2.1.). Analiza podsjetnika Timoteju
u 2 Tim 1,6-8 otkriva osnovnu značajku autentičnog služitelja Riječi, koja ga razlikuje od formalnog služitelja i koja se očituje samo u situaciji navještaja osporavane Riječi. Autentični služitelj ima karizmu
od Boga, te slijedi dinamiku Riječi i izlaže sebe poradi Riječi za spasenje drugih (2.2.2.). Formalni služitelj nema karizmu od Boga, te u navještaju slijedi ljudsku logiku i sputava osporavanu Riječ (2.2.1.). U
zaključku studije iznose se glavni rezultati i ukazuje na važnost crkvenog priznanja karizme Riječi, koje se može očitovati na razne načine, formalne i neformalne.

El objetivo de esta investigación fue documentar y analizar el uso, manejo y conocimiento local de las orquídeas asociados a celebraciones religiosas y culturales en comunidades rurales de los Municipios de Apaseo el Alto, Guanajuato y Tuxpan, Veracruz. Se seleccionaron para su estudio a Laelia autumnalis en Apaseo el Alto y a Oncidium sphacelatum en Tuxpan. Con un enfoque cualitativo, mediante recorridos de campo, observación participante y entrevistas a profundidad a mujeres de edad avanzada, jefes de familia, vendedores y a un cronista. Se encontró que Laelia autumnalis, “lirio” o “injerto” se utiliza como planta de ornato y los pseudobulbos para la elaboración de dulces con figuras alusivas a las celebraciones religiosas (Santa Cruz, San Bartolomé y San Juan.). Se produce a nivel de traspatio desde hace más de 100 años. Oncidium sphacelatum (orquídea de la Santa Cruz) se reproduce a nivel de solar o traspatio, con poblaciones muy abundantes. Se utiliza para la elaboración de cruces, o adornos de las mismas, las cuales “protegen” los hogares, negocios, construcciones en proceso, lapidas, cruces de caminos, etc., se utilizan exclusivamente los tallos florales que constituyen un simbolismo cultural para la población, en esta fecha religiosa, además de una fuente de ingreso. Se concluye que las especies estudiadas constituyen parte del patrimonio cultural y natural de las comunidades, aprovechándo estructuras vegetales (pseudobulbos que ya florearon y tallos florales) que no las pone en riesgo.

Post-neoliberalismo indócil. Agenda pública y relaciones socio-estatales en el Ecuador de la Revolución Ciudadana
Authors: Ramírez Gallegos Franklin
Published: October 2020

Luego de reconstruir el confictivo proceso de recomposición de la autonomía relativa de la acción estatal, el texto analiza la naturaleza y los avances de la estrategia post-neoliberal de la RC y refexiona sobre las ambivalencias de una lógica de gestión política centrada en la afrmación de su fuerza y capacidad decisional pero distante del apuntalamiento de un campo de relaciones políticas fuidas con la ciudadanía y las fuerzas organizadas de la sociedad.

Estrategias de negociación del FMI y la Argentina durante el período 2003-2004
Authors: Nemiña Pablo
Published: October 2020

El presente trabajo busca realizar un aporte en sentido tanto teórico como empírico, a la temática de la relación entre el FMI y Gobiernos prestatarios. En términos teóricos, desarrolla un esquema conceptual de doble nivel para sistematizar el estudio de procesos de negociación entre los actores citados. El análisis se centra en las estrategias que implementan los negociadores, las cuales, a su vez, están en relación con la posición negociadora y el estilo de negociación. En términos empíricos, presenta un análisis de las negociaciones entre el FMI y el Gobierno argentino durante el período 2003-2004 en base al esquema planteado. Se proponen dos hipótesis. Primero, si bien tanto el Gobierno como el FMI desplegaron estrategias confrontativas, el primero consiguió imponer su criterio en la mayoría de los temas confictivos porque articuló una posición negociadora de mayor fortaleza. Segunda, el Gobierno desplegó en la tercera revisión una estrategia confrontativa para evitar cumplir compromisos que abrían un conficto con su base de apoyo local, pero el Fondo profundizó su negativa a tolerar incumplimientos. Esto estancó la negociación y determinó la suspensión del acuerdo.
Gobierno de Lula y lulismo: examinando algunas hipótesis sobre las condiciones de posibilidad y la naturaleza del lulismo
Authors: Melamed de Menezes Thiago , Palermo Vicente
Published: October 2020

Con el éxito que, en general, se le atribuye a las dos gestiones de Lula, a partir de 2003, el debate acerca del llamado lulismo de a poco desplazólo que era hasta entonces una atención puesta en el Partido de los Trabajadores (PT), para focalizarse en Lula y su liderazgo. Apoyándose en laliteratura sobre el tema, el artículo examina distintas interpretaciones existentes, con el cuidadode distinguir entre las tesis respecto a las condicionesde posibilidad del lulismo y su análisiscomo fenómeno político.En relación a las primeras, son enfatizadas cuestiones como las distintas visiones acerca del modelo de acumulación que estuvo en vigor y de las políticas de redistribución de ingresos adoptadas durante sus dos administraciones. Se observan divergencias a la hora de determinar en qué medida el gobierno Lula siguió el modelo implantado por la administración que lo antecedió y a quése debería su mayor éxito político.En lo que atañe al segundo, las perspectivas divergen entre considerar el lulismo un nuevo ropaje para prácticas de ocupación y reparto del gobierno y verlo como un fenómeno de liderazgo que aportaría importantes contenidos de política.Los autores también presentan su propia hipótesis.
1983-2012: las etapas de la transición a la democracia argentina (en claves sociológicas)
Authors: Sidicaro Ricardo
Published: October 2020

Este artículo aborda las tres décadas de transición a la democracia desde las perspectivas conceptuales de Max Weber y de Pierre Bourdieu. El autor considera que los habitus creados durante la república militar (1930-83) constituyen una cultura política que obstaculiza un normal desarrollo político. Se dividen dos etapas. Durante la primera se observa la formación de un campo político y  de una clase política que entraron en colapso con las protestas de 2001. En la siguiente, se inició una aguda crisis de los partidos políticos que hoy plantea serios interrogantes sobre el futuro de las instituciones.
La Universidad como sujeto político en los ‘90. El Consejo Interuniversitario Nacional y la elaboración de políticas sectoriales (1989-2003): el caso de la Comisión de Pautas Presupuestarias
Authors: Rodríguez Laura R.
Published: October 2020

Se comunican los resultados de una investigación sobre la actuación del Consejo Interuniversitario Nacional en el proceso de elaboración e implementación de políticas sectoriales: la incorporación de “fórmulas” para la distribución de fondos incrementales entre las Universidades Nacionales entre 1989 y 2003, en el marco de un cambio sustancial de las relaciones entre el Estado y la Universidad, de la política universitaria en general y del financiamiento en particular. Se postula que las posibilidades del Consejo Interuniversitario Nacional (CIN) como espacio de construcción de acuerdos autónomos, fueron marcadas por condiciones de subordinación, manifiestas en el plano material y simbólico, y reflejadas dialécticamente en la erosión de su poder de incidencia en la elaboración depolíticas en virtud de su fragilidad organizativa, una amenazada legitimidad de representación sectorial, y el predominio de una posición reactivaen condiciones de ajuste estructural y disputa hegemónica. El interés central fue comprender la particular distribución de poder y estructura del juego de fuerzas que conformaron las posibilidades y límites de la Universidad para debatir críticamente y construir acuerdos democráticos sobre prioridades y contenidos de una política universitaria posible.
La cooperación internacional en materia agrícola y rural. La experiencia reciente en Argentina
Authors: Sili Marcelo
Published: October 2020

La cooperación internacional en materia agrícola y rural ha tenido un rol importante en Argentina, en tanto que el aprendizaje realizado permite orientar mejor el impacto de nuevos proyectos de cooperación. Interesa resaltar tres elementos: a) la cooperación en materia agrícola y rural es muy específca pues los agentes deben mantener un enfoque integral de las problemáticas del país, apelando a soluciones innovadoras adaptadas a contextos locales; b) los proyectos de cooperación son espacios de aprendizaje compartidos entre múltiples actores; c) la cooperación entre países de América latina es una fuente privilegiada de información para mejorar las prácticas de cooperación. Estos elementos tienen lugar en un contexto de cambio de las lógicas de cooperación en el que se observa el pasaje de un modelo de cooperación centrado en suplir las fallas de mercado, al fortalecimiento de los agentes para enfrentar las condiciones de funcionamiento de mercados e instituciones existentes.

La cuestión del Estado en las teorías neoschumpeterianas de la innovación y el desarrollo
Authors: Borrastero Carina Mariana
Published: October 2020

El objetivo general del trabajo es analizar las concepciones del Estado y su rol en los procesos de innovación y desarrollo en las teorías evolucionistas neoschumpeterianas. Proponemos un análisis conceptual de las obras principales de cuatro referentes: Nelson y Winter, Dosi, Lundvall y Pérez, desde una perspectiva crítica que problematiza sus aportes y límites para unacomprensión multidimensional de la innovación y el desarrollo. Constatamos la centralidad de la cuestión del Estado a partir de una exploración de la arquitectura conceptual general de las teorías de estos autores. Indagamos en la relación entre los presupuestos teóricos expresados en el discurso teórico de los autores y el peso específico y profundidad conceptual que  adquiere la cuestión del Estado en sus análisis. Sugerimosque los autores sostienen una concepción restringida del Estado que plantea dificultades teóricas de relevancia para pensar los procesos de innovación y desarrollo. En función de ello  planteamos la necesidad de pasar del Estado como elemento dado en la teoría al Estado como objeto de estudio, sin dejar de reconocer la fecundidad de estas teorías para pensar los problemas asociados a la producción, circulación y consumo deconocimiento al interior de los sistemas sociales y sus implicancias para el desarrollo.
Las políticas públicas de Ciencia y Tecnología en Argentina: un balance del período 2003-2015
Authors: Unzué Martín , Emiliozzi Sergio
Published: October 2020

El presente trabajo plantea un análisis de las innovaciones y las continuidades que se implementaron en el campo de las políticas públicas de Ciencia y Tecnología (CyT) a lo largo del ciclo de gobiernos kirchneristas, destacando en primer lugar que la conformación de una agenda de temas en el área no fue uniforme en el transcurso del período 2003-2015.Se propondrá distinguir entre los sentidos iniciales de las políticas de CyT (período 2003-2006) que se desplegaron en medio de un contexto complejo, y donde las prioridades parecían estar en otras áreas de gobierno, a lo que le sigue un ciclo de crecimiento de la inversión y de expansión del área, concomitante con la decisión de otorgarle una mayor visibilidad a la vinculación entre CyT y desarrollo económico (período 2007-2010).Finalmente, se analizará el ciclo de ajustes sobre esa idea de crecimiento, que se despliegan desde el 2010 hasta el final del mandato presidencial, y que buscan explorar, con distinta suerte, formas de construcción de gobernabilidad sobre la comunidad de investigadores, y de orientación del trabajo científico.
