A Critical Approach to Multiliteracy: Automates Intelligents
In this paper we present and analyse a website with a complex rhyzomatic structure
in connection with the results of a cybertask in which students were asked to read various
information sources by navigating a range of websites. The results and discussion include
issues such as: a) culture of learning and students’ task representation; b) possible relationships
between learning styles and ways of navigating and managing information to solve a task; c)
criteria students use to evaluate their navigation practice
Interculturalité et fonctionnement des flux d’information dans l’écriture hypertextuelle. Réflexions pour une approche pédagogique
En este estudio describimos cómo se
teje la estructura interna de dos sitios web
(uno francés y otro inglés) al mismo
tiempo que formulamos hipótesis sobre el
funcionamiento de los flujos de información
que aparecen en ellos. Mostramos los
aspectos plurilingües y multiculturales
sobre los que se sustentan y avanzamos
algunas hipótesis sobre las relaciones entre
los modelos ideológicos y los modelos
discursivos que emanan de los flujos de
información que se ofrecen a los visitantes-
lectores de dichos sitios. De este análisis
se deriva una serie de reflexiones que
nos permitirán elaborar propuestas
pedagógicas para la enseñanza-aprendizaje
de lenguas.This study describes how the internal
structure of two websites (in English and
French) is interwoven, and formulates a
series of hypotheses on the operation of the
information flows extant in each of them.
Apart from showing the multilingual and
multicultural issues upon which these hypotheses
are built, this study puts forward a
series of discourse models derived from the
information flows presented to the visitorsreaders
of those sites. This analysis yields a
series of reflections that will allow researchers
to elaborate pedagogic proposals focused
on the teaching and learning of languages
Are Spanish TTOs Prepared to Innovation in a COVID Context?
The analysis of the characteristics of Technology Transfer Offices (TTOs) is particularly
important as they constitute mediating units in the relationship between the market and university
research. They are responsible for the transfer and exploitation of knowledge arising in the university
context. Previous studies have been inconclusive as to the importance that the size, professionalisation
or age of TTOs might have on the transfer process. However, the need to explore new markets,
recognise new opportunities and identify potential customers points to the importance of TTOs
having a dual exploitative and exploratory orientation and an extensive relational network. More
recent research in the literature, based on ambidexterity and network theory, points to the impact
that these variables could have on change management and innovation in uncertain and changing
environments, such as those faced by TTOs in the current pandemic context. Therefore, the aim of this
paper is to analyse whether Spanish TTOs, due to their ambidextrous orientation at the organisational
and individual level, and their relational network with academic and market actors, are prepared
to promote innovation in a COVID-19 context. Based on a cluster analysis of 29 Spanish TTOs, our
results show that just a few of the Spanish TTOs surveyed would be prepared, from the perspective
of ambidexterity and their relational capital, to promote innovation in a COVID-19 context. In
conclusion, Spanish TTOs and their employees should focus more on ambidexterity and building
extensive relational capital so that, through mentoring, training, incubation or the provision of
various resources, they can help academics take advantage of the innovation opportunities offered
by the changing and uncertain environment.This work has been co-financed by the 2014-2020 ERDF Operational Programme and by the Department of Economy, Knowledge, Enterprise and Universities of the Regional Government of Andalusia.

The impact of human, social, and psychological capital on academic spin-off internationalization
Academic spin-offs (ASOs) are companies with a strong international vocation for two main reasons: first, they market their products and services in global market niches to profit from their high investment in R&D, characteristic of the sectors in which ASOs operate; and second, as a consequence of the international training and experience and of the international networks that the founding academic entrepreneurs of these companies tend to enjoy, derived from their scientific activity. Despite this natural tendency to internationalize, ASOs and specifically the founding academic entrepreneurs of these companies present certain difficulties in accessing resources for internationalization and in achieving credibility in foreign markets due to their university origins. Based on the resource-based view (RBV), and network theory (NT), this work proposes that the human capital, the social capital, and the psychological capital of the academic entrepreneur could compensate for these obstacles, providing key resources for the internationalization of their companies. The results contribute to the RBV, NT, and academic entrepreneurship and internationalization literature since they show that human capital, in terms of the international experience and training of the academic entrepreneur, their networks of relationships with international academic agents, and their psychological capital, are all antecedents of the internationalization of ASOs. However, the networks of academic entrepreneur relationships with international market agents appear to be irrelevant in the process of international expansion of ASOs.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.

The international orientation of academic entrepreneurship: the role of relational, human and psychological capital
Purpose Scholars have emphasized intellectual capital's importance for universities in obtaining competitive advantages and creating value. The purpose of this paper is to identify the influences of two components of intellectual capital, relational and human capital at the international level, and psychological capital on international orientation of academic entrepreneurs, and the mediating effects of international relational and human capital. Design/methodology/approach On the basis of a literature review, a theoretical model is proposed to explain the relationship between the studied variables. Our hypotheses are tested on a sample of 173 academic spin-offs of Spanish universities using bootstrapping methodology. Findings The results show that the international market relational capital and international human capital of academic entrepreneurs influence their international orientation, and that their psychological capital is directly, and indirectly, related to international orientation through international human capital and international market relational capital. Practical implications This study provides a better understanding of the antecedents of the international orientation of academic entrepreneurs, which would provide an important contribution to the literature on intellectual capital, academic entrepreneurship and internationalization. The achieved results highlight important implications for training of academic entrepreneurs and for managers and management teams of companies willing to enter, or even those already operating in, international markets. Originality/value In this study, the international orientation of academic entrepreneurs is explained through the psychological capital that is studied jointly with two components of intellectual capital, relational and human capital at the international level. Although some recent work has focused on the study of the internationalization of academic spin-off, this line of research is still incipient
Multifunctional albumin-stabilized gold nanoclusters for the reduction of cancer stem cells
Controlled delivery of multiple chemotherapeutics can improve the effectiveness of treatments and reduce side effects and relapses. Here in, we used albumin-stabilized gold nanoclusters modified with doxorubicin and SN38 (AuNCs-DS) as combined therapy for cancer. The chemotherapeutics are conjugated to the nanostructures using linkers that release them when exposed to different internal stimuli (Glutathione and pH). This system has shown potent antitumor activity against breast and pancreatic cancer cells. Our studies indicate that the antineoplastic activity observed may be related to the reinforced DNA damage generated by the combination of the drugs. Moreover, this system presented antineoplastic activity against mammospheres, a culturing model for cancer stem cells, leading to an efficient reduction of the number of oncospheres and their size. In summary, the nanostructures reported here are promising carriers for combination therapy against cancer and particularly to cancer stem cells.This research was funded by the Spanish Ministry of Economy and Competitiveness (CTQ2016-78454-C2-2-R, SAF2014-56763-R, and SAF2017-87305-R), Comunidad de Madrid (S2013/MIT-2850), Asociación Española Contra el Cáncer, and IMDEA Nanociencia IMDEA Nanociencia acknowledges support from the ‘Severo Ochoa’ Programme for Centres of Excellence in R&D (MINECO, Grant SEV-2016-0686
Impact of Nursing Methodology training sessions on completion of the Virginia Henderson assessment record
Producción CientíficaThe Virginia Henderson model, integrated in the computer application GACELA Care, helps to standardise the nursing assessment and establish precise and personalised nursing diagnoses. The aim was to determine the extent of completion of the initial patient assessment record after nurses following a training programme on nursing methodology. A quasi-experimental, retrospective, randomised, observational, single-group study was performed in two stages: pre-training and post-training. Voluntary training sessions were held for the nurses that work with GACELA Care. The completion of the initial patient assessment using the needs of Virginia Henderson and the Norton scale was evaluated before and after the training sessions. Completion of the needs of Virginia Henderson in the initial patient assessment increased from 94.2% to 100% (p = 0.014). Completion of “hygiene/skin” increased significantly from 83.3% to 95.8% (pre-training and post-training, respectively). The remaining needs did not show statistical significance. Recording of the Norton scale increased from 63.13% to 92.5% (p < 0.001). The training sessions on nursing methodology have improved the completion of records and inclusion of normal characteristics, defining characteristics and risk factors, and improving pressure ulcer risk assessment through the Norton scale
Analysis of burnout syndrome and resilience in nurses throughout the COVID-19 pandemic: A cross-sectional study
Producción CientíficaBackground: The COVID-19 pandemic has contributed to the occurrence of work-related stress on nursing staff. Being resilience an essential element to countering adversity. The aim of the study was to assess burnout syndrome as well as resilience in hospital-care nurses during the first outbreak of the COVID-19 pandemic. Methods: A cross-sectional descriptive study of burnout syndrome and resilience of 101 nurses during the first COVID-19 outbreak. The Maslach Burnout Inventory and the Scale of Resilience of Connor-Davidson were used. Results: The burnout average score was 74.35 ± 12.78 points, and resilience was 27.94 ± 5.84. Temporary nurses reached a lower average score for the emotional fatigue dimension (23.80 ± 10.39 points) p < 0.05. The emotional fatigue dimension correlated adversely with the average score of resilience (r = −0.271; p < 0.001). Conclusions: The level of burnout in nurses was high, being higher on those who took care of COVID-19 patients. Resilient nurses were able to better cope with stressful situations

3-Hydroxykynurenic acid: Physicochemical properties and fluorescence labeling
Quinoline is one of the most important heterocyclic systems in life sciences. Some derivatives are normal metabolites, and others are used as antibacterial, antimalarial, and anticancer agents. In this work, we describe the synthesis, physicochemical properties, and fluorescence features of a new 4-quinolinone fluorophore, 3-hydroxykynurenic acid (3-HOKA). 3-HOKA was obtained by alkoxide-induced rearrangement of ethyl isatinacetate followed by acidification and then alkaline hydrolysis. The fluorescent compound was characterized by NMR, MS, IR, and UV–Vis spectra. 3-HOKA can exist under a keto-enol equilibrium, but the 4-quinolinone form is the predominant tautomer. In PBS (pH = 7.4), the anionic keto form of 3-HOKA showed a maximum absorption at 368 nm, a fluorescence peak at 474 nm, and a fluorescence quantum yield (ΦF): 0.73. 3-HOKA is photostable and is a moderately weak oxygen generator. Viability assays on HeLa cells indicated that 3-HOKA did not induce significative cytotoxic effects. Under UV excitation, a bright blue fluorescence was selectively found in a singular body within the cytoplasm, a labeling pattern that suggests the possible localization of the probe in the centriole or related structures. Therefore, this novel fluorophore represents a promising prototype compound owing to its biocompatibility and potential biological applications.Fil: Shmidt, María Sol. Universidad de Buenos Aires.
