Research on Human Cognition for Biologically Inspired Developments
Authors: Wehle Marko , Weidemann Alexandra , Boblan Ivo Wilhelm
Published: October 2019

Robotic developments are seen as a next level in technology with intelligent machines, which automate tedious tasks and serve our needs without complaints. But nevertheless, they have to be fair and smart enough to be intuitively of use and safe to handle. But how to implement this kind of intelligence, does it need feelings and emotions, should robots perceive the world as we do as a human role model, how far should the implementation of synthetic consciousness lead and actually, what is needed for consciousness in that context? Additionally in Human-Robot-Interaction research, science mainly makes use of the tool phenomenography, which is exclusively subjective, so how to make it qualify for Artificial Intelligence? These are the heading aspects of this chapter for conducting research in the field of social robotics and suggesting a conscious and cognitive model for smart and intuitive interacting robots, guided by biomimetics.

Tourism marketing is a tool available for the managers that could establish a great connection between the visitors and the destinations, particularly if the promotions focus on the blue and the green economy. With some specific procedures, it is possible to take advantage in a competitive market that needs clear rules about the environment.
Cognitive Structure of Moral Reasoning, Development, and Evolution With Age and Pathology
Authors: Salvano-Pardieu Veronique , Oubrahim Leïla , Kilpatrick Steve
Published: October 2019

This chapter presents research on moral judgment from the beginning of the 20th century to the present day. First, the authors will present the contribution of Piaget and Kohlberg's work on moral development from childhood to adulthood as well as the work of Gilligan on moral orientation and the difference observed between men and women. Then, the authors will analyze underlying structures of moral judgment in the light of the Dual Process Theory with two systems: system 1: quick, deontological, emotional, intuitive, automatic, and system 2: slow, utilitarian, rational, controlled, involved in human reasoning. Finally, the model of Dual Process Theory will be confronted with data from moral judgment experiments, run on elderly adults with Alzheimer's disease, teenagers with Autism Spectrum Disorder, and children and teenagers with intellectual disability in order to understand how cognitive impairment affects the structures and components of moral judgment.
From Analogical to Analytical Thinking and Back
Authors: Pesce Sébastien
Published: October 2019

This chapter shows the importance for teachers to enter into a truly reflexive activity and to make it the main aspect of their professional activity. The author describes ways teachers can regain control over the activity of thinking and adapt their modes of reasoning to educational situations by developing control over the transition from system 1 to system 2. The aim is to consider the conditions for developing decision-making procedures, both reflexive and collective, when faced with complex situations (particularly crises), based on a deliberation rooted in a logic of inquiry.

Authors: Ribeiro Nerinéia Dalfollo , Steckling Skarlet De Marco , Maziero Sandra Maria , Klasener Greice Rosana
Published: October 2019

The development of early and upright common bean cultivars is necessary to meet the demand of producers. The objectives of this work were to evaluate more precise experimental statistics for the selection of early and upright common bean lines and identify the traits that provide better genetic differentiation between lines. For this purpose, 156 common bean lines of different grain colours were evaluated in 23 experiments carried out in the southern region of Brazil between 1998 and 2015. The traits related to earliness (flowering and cycle) and upright plant architecture (lodging, insertion of the first pod and insertion of the last pod) were evaluated with high experimental precision by determining F-test values for genotype (Fc), heritability (h2), and selective accuracy (SA). In the experiments with Fc ≥ 2.00, h2 ≥ 49.00%, and SA ≥ 0.70, the best genetic differentiation of early common bean lines was performed by the cycle; and the best genetic differentiation of common bean lines with upright plant architecture was carried out by the insertion of the first and the last pod.
Southern highland papaya (Vasconcellea quercifolia A. St.-Hil.): Do fruit ripening and harvesting time affect seed germination?
Authors: Urtasun María Manuela , Giamminola Eugenia Mabel , Viana Marta Leonor de
Published: October 2019

In this work, we report the effects of the harvesting time, the stages in fruit ripening and the influence of potassium nitrate in V. quercifolia seed germination. In addition, information about the storage period and light requirements is provided. Fruits were harvested at the beginning and at the end of the fruiting season, and they were classified into five ripening categories. Seed germination was evaluated with two factorial experiments: 1) harvesting time, fruit ripening, and pre-germination treatment; 2) storage and light requirements. The response variables were germination percentage, mean germination time, and seedling vigor. Seeds harvested at the beginning of the season appeared to be less dormant and they were not influenced by fruit ripening or pre-germination treatments. By contrast, seeds harvested at the end of the season were influenced by fruit ripening and pre-germination treatments. Light and seed storage had a positive effect on germination. Mean germination time varied from 12 to 40 days, and vigor index was positively influenced by potassium nitrate. V.quercifolia seeds are photoblastic positive at constant temperatures and their dormancy can be influenced by harvest time, fruit ripening and a storage period.

Improving the Adhesion between Pineapple Leaf Fiber and Natural Rubber by Using Urea Formaldehyde Resin
Authors: Tongphang Chanaporn , Hajjar Samar , Mougin Karine , Amornsakchai Taweechai
Published: October 2019

Green composites, especially that are reinforced with natural fibers, have received a great deal of attention due to the problems of global warming and resources depletion. Pineapple leaf fiber (PALF) is an interesting choice because of its high mechanical properties and it is obtained from agricultural waste. In this work PALF is combined with natural rubber (NR) to produce green rubber composite with enhanced mechanical properties. Since the two materials are so different in their stiffness and polarity, poor interfacial adhesion and thus low stress transfer, between NR and PALF may be expected. Attempts were made to use urea formaldehyde (UF) resin to improve the adhesion between PALF and NR. PALF was coated with different amounts of UF resin in solution. The fiber was characterized with FTIR, XPS and SEM. Uniaxially aligned PALF reinforced rubber composites with a fixed amount of 10 parts per hundred of rubber (phr) PALF were prepared. The adhesion between PALF and NR was evaluated from the tensile stress-strain curve and fracture surface of the composite. It was found that UF resin had negligible effect in improving the stress transfer but rather reduced it as shown in the stress-strain curve. Thicker coating of UF resin led to lower reinforcement effect and, hence, lower modulus. Stress at break, on the other hand, increased with increasing the coating thickness.
Structure and Mechanical Properties of Unheated Chromium Aluminum Nitride Coatings Sputter-Deposited with Various Aluminum Content

Published: October 2019

Chromium aluminum nitride (CrAlN) has been extensively studied because of high hardness, high oxidation and corrosion resistance, and good wear resistance. However, utilizing substrate treatments such as heating and voltage biasing during film deposition usually leads to relatively high surface roughness that affects wear rates. It has been found that sputter deposition at low substrate temperatures can produce nano-grain coatings with enhanced structure and mechanical properties. For this reason, the CrAlN in this study was prepared by a reactive co-sputtering technique without the substrate treatments. Effects of Al content on structure and mechanical properties were investigated by X-ray diffraction, field-emission scanning electron microscopy, energy-dispersive X-ray spectrometry, atomic force microscopy, X-ray photoelectron spectroscopy, and nanoindentation. The results suggest that these CrAlN films formed as solid solutions by substitution of Al for Cr in the CrN crystalline structure. The deposition with increasing Al but fixed N leads to N deficiency, therefore at high Al content these films form under 1:1 stoichiometric nitride. This lowers film crystallinity and hence refined film morphology. Surface roughness and hardness of the films decreased from 5.737 to 1.135 nm and from 31.69 to 26.56 GPa, respectively. However, the solid solution strengthening arising from the further increase of the Al content causes these values to rebound to 2.466 nm and to 30.16 GPa.

Overexpression of Beclin1 gene leads to reduction of telomerase activity in MDCK cells and enhances apoptosis
Authors: Taji Fatemeh , Abdoli Asghar , Baesi Kazem , Sheikholeslami Farzaneh , Kouchesfahani Homa Mohseni
Published: October 2019

Background:

Telomeres through maintaining chromosomal integrity have key roles in the cell life span. The autophagy is typically a pro-survival process and important for maintaining cellular homeostasis. Conversely, in some conditions, autophagy acts as caspase-independent cell death program. Beclin1 gene plays a principal role in the initiation of autophagy.

Objective:

The aim of this study was to evaluate the effect of autophagy induction via recombinant Beclin1 on telomerase activity and programmed cell death (apoptosis) in MCDK cells.

Materials and Methods:

The recombinant Beclin1-pcDNA3.1(-) was transfected into MDCK cells. Next, the autophagy information was detected by LC3II staining as autophagy marker using flow cytometry. The telomerase activity was measured by telomeric repeat amplification protocol method in MDCK cells. To detection of the cell death in MDCK cells, apoptosis assay was done through Annexin V staining method.

Results:

The results of flow cytometry analysis indicated that following overexpression of Beclin1 gene, the percentage of the LC3II was 16.08% compared with control group (0.48%). Following induction of autophagy, telomerase activity reduced 10 folds in comparison with the control group. The rate of apoptosis in transfected MDCK cells increased up to 12.74%.

Conclusion:

Crosstalk between telomerase, autophagy, and apoptosis may determine the fate of the cancer cell aging. Hence, manipulation of autophagy may create a novel area to design new compounds and combination therapy to shorten the cancer cell survival.

Authors: París Romia Gemma
Published: October 2019

Entendiendo el arte como espacio de encuentro, el proyecto Espacio C invita jóvenes artistas a realizar una residencia en escuelas de Barcelona, con el objetivo principal de crear sinergias entre arte y educación. La escuela cede un espacio para crear un taller artístico, el cual utilizará el artista residente y los niños y niñas de la escuela. El taller se convierte en un espacio compartido, donde el aprendizaje aparece por contaminación, entre el mundo adulto y la infancia. Esta investigación muestra algunas de las influencias que los artistas provocan en los niños y niñas; así como los cambios en los procesos creativos de los artistas, generados por su contacto con los procesos de la infancia. La investigación ha sido realizada des de una perspectiva de Investigación Educativa basada en las Artes, con la intención de revelar estrategias de mejora en educación artística. La narrativa visual Cables y Rizomas, construida mediante el diálogo entre fotografías propias y pinturas de Juan Uslé (Santander, 1954), forma parte de los resultados de la investigación. Este Foto Ensayo sitúa el lector en un sistema rizomático de relaciones y aprendizajes compartidos. Como artista/docente/investigadora propongo, más que obtener datos objetivos sobre un tema educativo, participar en la creación de conocimiento en relación el mundo educativo, invitando al lector a cuestionarse sus propias preguntas y posicionarse con este.
New pragmatism by G.W. Kołodko: an alternative or a supplement to pure economic theory?
Authors: Nekipelov Aleksandr
Published: October 2019

The article is devoted to finding the answer to the following question: is the concept of the new pragmatism developed by Professor G.W. Kołodko an alternative or a supplement to the general economic theory? The author’s position is that the positive potential of the new pragmatism consists in its practical usefulness for the analysis of specific situations developing both in various national economies, as well as in the global economy, based on the interdisciplinary grounds. This concept should not be considered as an alternative to the general economic theory. Rather, it is a kind of a bridge over the “area of uncertainty”, which necessarily exists between an abstract economic theory and the economic reality.

Perspectives on the use of lipoic acid in the support of disease treatment*
Authors: Skibska Beata , Gorąca Anna
Published: October 2019

Lipoic acid (LA) is a natural compound present in food and used as a dietary supplement. LA is endogenously synthetized in small amounts from octanoid acid in the mitochondria. This compound occurs naturally in vegetables such as spinach, broccoli and in animal tissues, in the kidneys, heart and liver. It has been shown that LA is a cofactor in the multienzyme complexes that are responsible for oxidative decarboxylation of α- ketoacids. LA and its reduced form, dihydrolipoic acid (DHLA), have many biological functions leading to a wide variety of actions such as anti-inflammation and antioxidant protection, scavenging of reactive oxygen species, regenerating other antioxidant agents, such as vitamins C and E, and cytosolic glutathione, chelating the transitional metal ions (e.g. iron and copper), and modulating the signal transduction of nuclear factor. Many authors regard LA as a potentially useful agent in the treatment and/or prevention of many diseases such as diabetes mellitus, overweight, obesity, hypertension, heart diseases, inflammation. This review concentrates on the role of LA in the treatment of diabetes mellitus, obesity, inflammation and blood pressure regulation. LA can be considered as a potentially useful drug in treatment of many diseases, particularly those related to excessive production of free radicals.

Phenotypic characteristics and comparative evaluation of preserved animals from Lithuanian pig breeds
Authors: Razmaitė Violeta , Jatkauskienė Virginija
Published: October 2019

The aim of the study was phenotypic characterization and comparative evaluation of Lithuanian Indigenous Wattle and Lithuanian White pigs. Physical measurements were taken only from a representative set of adult animals: sows and boars. Evaluation of breeds included discrete (qualitative) and quantitative variables and was performed according to the Guidelines of FAO for Phenotypic Characterization of Animal Genetic Resources. The data were subjected to the analysis of variance in general linear (GLM) and discriminant analysis procedures in SPSS 17. The qualitative characterization of preserved animals validated the characteristics of Lithuanian pig breeds described in old literature. The comparative evaluation of the physical measurements of Lithuanian White and Lithuanian Indigenous Wattle pigs showed the highest significant differences in body, ear and tail length. Due to the different physiological status of females the statement that Lithuanian White pigs are larger animals than Lithuanian Indigenous Wattle pigs better confirms the weight and body dimensions of males. Small differences in body dimensions were found only between the youngest animal groups under 24 months of age and older animals. However, the results of the canonical discriminant analysis did not give any evidence that pigs of different age have different characteristics.

La confiance et son corollaire la défiance sont au coeur du lien qui unit les citoyens avec leurs institutions et les hommes et les femmes qui les dirigent. Pour autant, comme le confirment de nombreuses études, les citoyens français ont une bien meilleure confiance dans leurs institutions publiques locales et particulièrement la mairie. La proximité jouerait un rôle important dans la construction de la confiance entre les habitants et leur mairie. En nous adossant aux résultats du Baromètre du Service Public Municipal que nous avons élaboré et portant sur un échantillon de 1010 répondants français, notre article identifie des liens fragiles entre la proximité et la confiance accordée aux services publics municipaux. Ces liens diffèrent notamment selon la nature de la proximité institutionnelle, relationnelle ou organisationnelle.

Le processus d’internationalisation peut parfois se justifier par la recherche de matières premières dans certaines zones géographiques. Les aspects relationnels, institutionnels et administratifs se révèlent bien souvent au coeur de la stratégie d’internationalisation. L’utilisation de « l’intelligence juridique » doit ainsi être intégrée dans ce type de stratégies. Néanmoins, comment articuler développement international et approches juridiques ? Peut-on identifier certaines logiques ou régularités ? Cet article entend répondre à ces différentes questions en insistant notamment sur l’évolution des contextes des transactions internationales, à travers l’étude comparée de deux contrats extractifs Sud-Sud.

Authors: Keramidas Olivier , Le Pennec Ekaterina , Serval Sarah
Published: October 2019

Cet article s’intéresse à l’attractivité d’un territoire : la région de Kalouga en Russie. L’objectif porte sur le lien théorique et empirique entre action publique locale et localisation des entreprises multinationales (EMN) pour en expliquer l’attractivité. L’approche choisie est celle des ressources échangées afin de mettre en perspective l’action publique en matière d’attractivité (Colletis et Pecqueur, 2005). L’étude empirique est fondée sur l’analyse de 5 processus d’implantation d’EMN européennes dans la région de Kalouga. Les résultats révèlent que les ressources territoriales décisives mises à disposition des EMN par les acteurs territoriaux sont de nature idéelle, informationnelle et relationnelle.

Authors: Cheillan Hervé , Enjolras Geoffroy , Guieu Gilles
Published: October 2019

La question des déterminants de la performance, tant économique que sociale, des stratégies de création de produits au bas de la pyramide économique (Bottom of the Pyramid - BoP) reste encore aujourd’hui posée. La méthode mobilisée ici pour répondre à cette question est le sondage de cas, une forme de méta-analyse qui permet de capitaliser les conditions et les résultats des études antérieures. D’une part, l’étude statistique du sondage de cas met en exergue un ensemble de variables discriminantes comme la qualité ou l’adaptation, d’autre part, elle valide l’existence d’une relation positive entre la performance économique et la performance sociale.
Révolutions européennes et théâtre à la Congrégation de Notre-Dame, 1868-1871
Authors: Plourde Julie
Published: October 2019

Au tournant des années 1870, les filles de la Congrégation de Notre-Dame ont joué, entre les murs des couvents, des pièces théâtrales à caractère politique. Dépeignant les révolutionnaires européens de l’époque sous les traits de Satan, ces pièces ont permis de financer l’envoi des zouaves en Italie. Les filles ont aussi, sans nécessairement le savoir, participé à la quête de Mgr Bourget d’éradiquer les idées libérales et de propager l’ultramontanisme dans la bourgeoisie canadienne-française.

Authors: Stijepić Ilija
Published: October 2019

For the majority of mature adults, the maintenance of independent functioning, intact cognitive abilities, and good mental status could be the most important achievements in late life. Functional fitness is defined as the physical capacity to perform daily activities independently and without the appearance of fatigue. Functional fitness can be measured using the Senior Fitness Test – SFT. The experimental group consisted of 30 men mean age 76,9±6,27. Participants completed a 12-week strength and balance exercise program. The participants were evaluated before and after completing the exercise program for lower- and upper-body strength, aerobic endurance, lower- and upper-body flexibility, agility and dynamic balance. To determine the changes in particular parameters, paired samples T-test was used. The statistical significance was set at p<0.05. Statistically significant improvements were found in all tests.

Chlamydia trachomatis‐infected human cells convert ceramide to sphingomyelin without sphingomyelin synthases 1 and 2

Published: October 2019

The obligate intracellular bacterium Chlamydia trachomatis proliferates in the membranous compartment inclusion formed in host cells. The host ceramide transport protein CERT delivers ceramide from the endoplasmic reticulum to the Golgi complex for the synthesis of sphingomyelin (SM). Chlamydia trachomatis has been suggested to employ CERT to produce SM in the inclusion by host SM synthases (SMSs). Here, we found that C. trachomatis proliferates and produces infective progeny even in SMS1 and SMS2 double‐knockout HeLa cells, but not in the SMS1/SMS2/CERT triple‐knockout cells. Interestingly, infected cells convert ceramide to SM without host SMSs. These results suggest that C. trachomatis‐infected cells can convert ceramide to SM without host SMSs after CERT‐mediated transfer of ceramide to the inclusions.

Authors: El Majdoub Faycal , Neudorfer Clemens , Richter Ronald , Schieferdecker Simon , Maarouf Mohammad
Published: October 2019

Objective

Spinal Cord Stimulation (SCS) overlaps painful areas with paresthesia to alleviate pain. Ten kHz High‐Frequency SCS (HF10 cSCS) constitutes a treatment option that can provide pain relief without inducing paresthesia. In this retrospective, open‐label study, we evaluated the efficacy of HF10 cSCS in chronic neck and/or upper limb pain.

Methods

Between May 2015 and August 2017, 24 consecutive patients with neck and/or upper limb pain were treated with HF10 cSCS. The patients’ mean age was 61.4 years (range: 40.1–82.6 years). The mean neck and upper limb pain at baseline was 8.8 (range: 7.0–10) and 7.5 (range: 6.0–9.0) according to the visual analog scale (VAS). Functionality was evaluated using the Oswestry Disability Index (ODI). To assess health‐related psychological impairment, we used the Global Assessment of Functioning questionnaire.

Results

Twenty‐three patients responded to treatment. Pain intensity reduced significantly to a mean score of VAS 2.5 (range: 2.0–4.0) for neck and 2.0 (range: 1.0–3.0) for upper limb pain after 6 months. At 12 months, VAS scores for neck and upper limb pain reduced to 2.2 (range: 1.0–3.0) and 1.7 (range: 1.0–3.0), respectively. Mean ODI scores decreased from 31 (range: 21–42) at baseline to 19.9 (range: 8–26) after 12 months. In three patients, infection of the IPG pocket occurred r and 8.7 months after surgery. One patient has had lead migration resulting in a surgical revision.

Interpretation

HF10 cSCS therapy has proven to be effective in reducing neck and upper limb pain significantly and increasing functional capacity. These results warrant further studies with larger patient series and longer follow‐ups.
Electronic Properties of {112} and {110} Twin Boundaries in Anatase TiO2
Authors: Quirk James A. , Lazarov Vlado K. , McKenna Keith P.
Published: October 2019

First‐principles calculations of the electronic structure and charge‐trapping behavior of Σ3 {112} and Σ1 {110} twin boundaries (TBs) in anatase TiO2 are performed using an accurate hybrid density functional theory approach. The former is characterized experimentally using transmission electron microscopy (TEM) and very good agreement on the structure is found. The {110} twin has not yet been observed but TEM and scanning tuneling microscopy (STM) image simulations are presented to aid experimental identification. Holes are found to trap in a polaronic configuration at both the twin boundaries. The {112} TB presents more favorable sites for hole polaron formation at the boundary with trapping energies 0.16–0.18eV, more favorable than the bulk. The {110} TB presents hole polaron trapping sites ranging from 0.07 eV, less favorable, to 0.14 eV, more favorable, than the bulk. Neither boundary is found to favor electron trapping, indicating they are relatively benign to the performance of anatase as an n‐type conductor.
Copernicium: A Relativistic Noble Liquid
Authors: Mewes Jan‐Michael , Smits Odile R. , Kresse Georg , Schwerdtfeger Peter
Published: October 2019

The chemical nature and aggregate state of superheavy copernicium (Cn) have been subject of speculation for many years. While strong relativistic effects render Cn chemically inert, which led Pitzer to suggest a noble‐gas‐like behavior in 1975, Eichler and co‐workers in 2008 reported substantial interactions with a gold surface in atom‐at‐a‐time experiments, suggesting a metallic character and a solid aggregate state. Herein, we explore the physicochemical properties of Cn by means of first‐principles free‐energy calculations, which confirm Pitzer's original hypothesis: With predicted melting and boiling points of 283±11 K and 340±10 K, Cn is indeed a volatile liquid and exhibits a density very similar to that of mercury. However, in stark contrast to mercury and the lighter Group 12 metals, we find bulk Cn to be bound by dispersion and to exhibit a large band gap of 6.4 eV, which is consistent with a noble‐gas‐like character. This non‐group‐conforming behavior is eventually traced back to strong scalar‐relativistic effects, and in the non‐relativistic limit, Cn appears as a common Group 12 metal.
Carboxy Group as a Remote and Selective Chelating Group for C−H Activation of Arenes
Authors: Li Shangda , Wang Hang , Weng Yunxiang , Li Gang
Published: October 2019

The first example of carboxy group assisted, remote‐selective C(sp2)−H activation with a PdII catalyst has been developed and proceeds through a possible κ2 coordination of the carboxy group, thus suppressing the ortho‐C−H activation through κ1 coordination. Besides meta‐C−H olefination, direct meta‐arylation of hydrocinnamic acid derivatives with low‐cost aryl iodides has been achieved for the first time. These findings may motivate the exploration of novel reactivities of the carboxy assisted C−H activation reactions with intriguing selectivities.
Selective Late‐Stage Sulfonyl Chloride Formation from Sulfonamides Enabled by Pyry‐BF4
Authors: Gómez‐Palomino Alejandro , Cornella Josep
Published: October 2019

Reported here is a simple and practical functionalization of primary sulfonamides, by means of a pyrylium salt (Pyry‐BF4), with nucleophiles. This simple reagent activates the poorly nucleophilic NH2 group in a sulfonamide, enabling the formation of one of the best electrophiles in organic synthesis: a sulfonyl chloride. Because of the variety of primary sulfonamides in pharmaceutical contexts, special attention has been focused on the direct conversion of densely functionalized primary sulfonamides by a late‐stage formation of the corresponding sulfonyl chloride. A variety of nucleophiles could be engaged in this transformation, thus permitting the synthesis of complex sulfonamides, sulfonates, sulfides, sulfonyl fluorides, and sulfonic acids. The mild reaction conditions and the high selectivity of Pyry‐BF4 towards NH2 groups permit the formation of sulfonyl chlorides in a late‐stage fashion, tolerating a preponderance of sensitive functionalities.
