Existence of Global Solutions for Nonlinear Magnetohydrodynamics with Finite Larmor Radius Corrections
Authors: Elsrrawi Fariha , Hattori Harumi
Published: January 2018

We discuss the existence of global solutions to the magnetohydrodynamics (MHD) equations, where the effects of finite Larmor radius corrections are taken into account. Unlike the usual MHD, the pressure is a tensor and it depends on not only the density but also the magnetic field. We show the existence of global solutions by the energy methods. Our techniques of proof are based on the existence of local solution by semigroups theory and a priori estimate.
Spatial Heterogeneity and Evolutionary Dynamics Modulate Time to Recurrence in Continuous and Adaptive Cancer Therapies

Published: January 2018

Treatment of advanced cancers has benefited from new agents that supplement or bypass conventional therapies. However, even effective therapies fail as cancer cells deploy a wide range of resistance strategies. We propose that evolutionary dynamics ultimately determine survival and proliferation of resistant cells. Therefore, evolutionary strategies should be used with conventional therapies to delay or prevent resistance. Using an agent-based framework to model spatial competition among sensitive and resistant populations, we applied antiproliferative drug treatments to varying ratios of sensitive and resistant cells. We compared a continuous maximum-tolerated dose schedule with an adaptive schedule aimed at tumor control via competition between sensitive and resistant cells. Continuous treatment cured mostly sensitive tumors, but with any resistant cells, recurrence was inevitable. We identified two adaptive strategies that control heterogeneous tumors: dose modulation controls most tumors with less drug, while a more vacation-oriented schedule can control more invasive tumors. These findings offer potential modifications to treatment regimens that may improve outcomes and reduce resistance and recurrence.

Significance: By using drug dose modulation or treatment vacations, adaptive therapy strategies control the emergence of tumor drug resistance by spatially suppressing less fit resistant populations in favor of treatment sensitive ones. Cancer Res; 78(8); 2127–39. ©2018 AACR.
Immunooncology in Breast Cancer: Active and Passive Vaccination Strategies
Authors: Schütz Florian , Marmé Frederik , Domschke Christoph , Sohn Christof , von Au Alexandra
Published: January 2018

Immunotherapies are set to become part of the therapeutic repertoire for breast cancer in the near future. Active vaccination is a promising strategy, especially in tumors that have a specific tumor-associated antigen. Although cellular immunotherapies have not yet shown efficacy, new technologies are on the way to improve this approach. Given the recent Food and Drug Administration approval of chimeric antigen receptor (CAR) T cells for leukemia, it is only a question of time before solid tumors will follow. However, not all breast cancer patients will respond to cellular or other immunotherapy. Hence, we must define subpopulations of breast cancer patients who benefit from this new approach.
Interações atlânticas entre Salvador e Porto Novo (Costa da Mina) no século XVIII
Authors: Silva Junior Carlos Francisco da
Published: January 2018

O artigo discute as dinâmicas atlânticas entre Salvador e Porto Novo, na Costa da Mina, durante o século XVIII. A despeito do foco da historiografia brasileira no tráfico baiano em Uidá, os portos a leste – os chamados “portos de baixo” – foram importantes terminais de deportação de africanos para as Américas. O artigo explorará ainda as dinâmicas entre Porto Novo e o Daomé, principal reino traficante do golfo do Benim no século XVIII, que reivindicava o “monopólio” do tráfico na região. O jogo político do tráfico de escravos envolvia entidades africanas locais, traficantes de diversas carreiras e autoridades coloniais. Observar as interações entre a Bahia e Porto Novo iluminará as diferentes fases do comércio atlântico no golfo do Benim no século XVIII
O intérprete latino-americano: trajetória intelectual e discursos de Francisco García Calderón
Authors: Gouveia Regiane Cristina
Published: January 2018

A produção intelectual latino-americana do final do século XIX e início do XX caracteriza-se pelo ensaio, gênero literário flexível que trabalha com uma diversidade de temas tratados a partir do ponto de vista pessoal do autor. Este artigo analisa a trajetória intelectual, o contexto de produção e a obra Las democracias de América (1912), do ensaísta peruano Francisco García Calderón que, no início do século XX, foi considerado como um dos intelectuais mais importantes pela intelectualidade do período. Destacam-se a defesa da latinidade pelo escritor peruano como forma de salvar a América Latina do imperialismo praticado pelas potências estrangeiras, bem como o problema da raça visto por García Calderón como um dos fatores responsáveis pela difícil situação do continente.
O castigo senhorial e a abolição da pena de açoites no Brasil: Justiça, imprensa e política no século XIX
Authors: Pirola Ricardo Figueiredo
Published: January 2018

O objetivo deste artigo é analisar a criação da lei de 15 de outubro de 1886 que aboliu a pena de açoites no Brasil. Diferentemente da historiografia dedicada ao tema que destacou o contexto antiescravista internacional e as disputas parlamentares, pretendo olhar para os debates travados no âmbito da Justiça e da imprensa a partir do estudo de três casos que tiveram grande repercussão nas décadas de 1870 e 1880. Minha intenção é demonstrar como as discussões parlamentares para a abolição da pena de açoites no Brasil relacionavam-se a um amplo debate de crítica aos castigos físicos nos anos finais da escravidão.

A historiografia do Império Romano tardio: do Estado máximo ao Estado mínimo, e de volta outra vez
Authors: Silva Uiran Gebara da
Published: January 2018

Este artigo analisa os modelos conceituais de Estado utilizados pela historiografia sobre o Império romano tardio ao longo do século XX. A argumentação busca demonstrar que é possível observar uma alternância entre concepções opostas de Estado, ora maximalistas, ora minimalistas e que tais concepções quase sempre se apresentam como estruturas explicativas da história do Império romano tardio, considerando a extensão do Estado como causa da desarticulação ou da manutenção do sistema romano no Mediterrâneo. O texto analisa a historicidade dessas concepções, e demonstra sua conexão com o debate entre modernismo e primitivismo na economia antiga; critica igualmente os pressupostos e a quase ubiquidade das categorizações e ideologias liberais na historiografia (mesmo entre autores marxistas). Na conclusão demonstramos como a oposição historiográfica entre concepções minimalistas e maximalistas obscurecem o entendimento das relações de classe desenvolvidas no interior do sistema de governo imperial romano tardio.

Dynamic Neural Turing Machine with Continuous and Discrete Addressing Schemes
Authors: Gulcehre Caglar , Chandar Sarath , Cho Kyunghyun , Bengio Yoshua
Published: January 2018

We extend the neural Turing machine (NTM) model into a dynamic neural Turing machine (D-NTM) by introducing trainable address vectors. This addressing scheme maintains for each memory cell two separate vectors, content and address vectors. This allows the D-NTM to learn a wide variety of location-based addressing strategies, including both linear and nonlinear ones. We implement the D-NTM with both continuous and discrete read and write mechanisms. We investigate the mechanisms and effects of learning to read and write into a memory through experiments on Facebook bAbI tasks using both a feedforward and GRU controller. We provide extensive analysis of our model and compare different variations of neural Turing machines on this task. We show that our model outperforms long short-term memory and NTM variants. We provide further experimental results on the sequential [Formula: see text]MNIST, Stanford Natural Language Inference, associative recall, and copy tasks.
Coexistence of Stochastic Oscillations and Self-Organized Criticality in a Neuronal Network: Sandpile Model Application
Authors: Saeedi Alireza , Jannesari Mostafa , Gharibzadeh Shahriar , Bakouie Fatemeh
Published: January 2018

Self-organized criticality (SOC) and stochastic oscillations (SOs) are two theoretically contradictory phenomena that are suggested to coexist in the brain. Recently it has been shown that an accumulation-release process like sandpile dynamics can generate SOC and SOs simultaneously. We considered the effect of the network structure on this coexistence and showed that the sandpile dynamics on a small-world network can produce two power law regimes along with two groups of SOs—two peaks in the power spectrum of the generated signal simultaneously. We also showed that external stimuli in the sandpile dynamics do not affect the coexistence of SOC and SOs but increase the frequency of SOs, which is consistent with our knowledge of the brain.
Muscle Synergy–Driven Robust Motion Control
Authors: Min Kyuengbo , Iwamoto Masami , Kakei Shinji , Kimpara Hideyuki
Published: January 2018

Humans are able to robustly maintain desired motion and posture under dynamically changing circumstances, including novel conditions. To accomplish this, the brain needs to optimize the synergistic control between muscles against external dynamic factors. However, previous related studies have usually simplified the control of multiple muscles using two opposing muscles, which are minimum actuators to simulate linear feedback control. As a result, they have been unable to analyze how muscle synergy contributes to motion control robustness in a biological system. To address this issue, we considered a new muscle synergy concept used to optimize the synergy between muscle units against external dynamic conditions, including novel conditions. We propose that two main muscle control policies synergistically control muscle units to maintain the desired motion against external dynamic conditions. Our assumption is based on biological evidence regarding the control of multiple muscles via the corticospinal tract. One of the policies is the group control policy (GCP), which is used to control muscle group units classified based on functional similarities in joint control. This policy is used to effectively resist external dynamic circumstances, such as disturbances. The individual control policy (ICP) assists the GCP in precisely controlling motion by controlling individual muscle units. To validate this hypothesis, we simulated the reinforcement of the synergistic actions of the two control policies during the reinforcement learning of feedback motion control. Using this learning paradigm, the two control policies were synergistically combined to result in robust feedback control under novel transient and sustained disturbances that did not involve learning. Further, by comparing our data to experimental data generated by human subjects under the same conditions as those of the simulation, we showed that the proposed synergy concept may be used to analyze muscle synergy–driven motion control robustness in humans.

Published: January 2018

Two Eugenia species are described herein as result of the elaboration of a taxonomic treatment of Myrtaceae for the flora of Restinga vegetation from Espírito Santo, in the Brazilian Atlantic forest. Detailed description, illustration, distribution and evaluation of their IUCN conservation status of Eugenia itaunensis and Eugenia kuekii are presented. Eugenia itaunensis is related to E. copacabanensis from which differs by larger leaves with base obtuse, rounded, cordate or subcordate, 10–18 pairs of secondary veins and greater flowers with calyx lobes in two unequal pairs in size. Eugenia kuekii is morphologically similar to Eugenia widgrenii but differs by leaves with obtuse base, 6–9 pairs of secondary veins, fasciculiform inflorescence with 1–2 pairs of flowers, and yellowish fruits. Eugenia kuekii is also related to Eugenia pruinosa but can be distinguished by its leaves with base obtuse or rounded and calyx lobes larger.
Puccinia neovelutina nom. nov., a replaced name for Aecidium elaeagni and its new aecial host from Japan
Authors: KAKISHIMA MAKOTO , JI JING-XIN , KASUYA TAIGA
Published: January 2018

The life cycle of the aecial stage of a rust fungus found on Elaeagnus umbellata var. rotundifolia in Chiba, Japan was clarified by inoculations. This rust fungus was morphologically identified as Puccinia velutina (anamorph: Aecidium elaeagni) alternating between Carex lenta and Elaeagnus species. This plant is a new host for this rust fungus. However, the current International Code of Nomenclature (ICN, Melbourne 2012) has abolished the distinction between “anamorph” and “teleomorph” names, and we propose a new name, P. neovelutina as a replaced name for A. elaeagni, because Puccinia elaeagni is a preoccupied available name. Its epitype specimen is designated.

Published: January 2018

Activation of melatonin receptors protects the heart against ischemia-reperfusion injury. Ramelteon, a clinically used drug for insomnia, acts via activation of melatonin receptors. We investigated whether ramelteon induces acute infarct size reduction by postconditioning. Male Wistar rats were randomized to 6 groups. Hearts were treated with melatonin and ramelteon at the beginning of reperfusion. The melatonin receptor inhibitor luzindole was administered with and without melatonin and ramelteon, respectively. Ramelteon reduced infarct size to the same extent as melatonin. Both effects were completely abolished by luzindole. The results show for the first time that ramelteon induces cardioprotection by postconditioning.
Tracing the destiny of mesenchymal stem cells from embryo to adult bone marrow and white adipose tissue via Pdgfrα expression
Authors: Miwa Hiroyuki , Era Takumi
Published: January 2018

Mesenchymal stem cells (MSCs) are somatic stem cells that can be derived from adult bone marrow (BM) and white adipose tissue (WAT), and that display multipotency and self-renewal capacity. Although MSCs are essential for tissue formation and have already been used in clinical therapy, the origins and markers of these cells remain unknown. In this study, we first investigated the developmental process of MSCs in mouse embryos using the gene encoding platelet-derived growth factor receptor α (Pdgfra) as a marker. We then traced cells expressing Pdgfra and other genes (brachyury, Sox1 and Pmx1) in various mutant mouse embryos until the adult stage. This tracing of MSC origins and destinies indicates that embryonic MSCs emerge in waves and that almost all adult BM MSCs and WAT MSCs originate from mesoderm and embryonic Pdgfrα-positive cells. Furthermore, we demonstrate that adult Pdgfrα-positive cells are involved in some pathological conditions.

5,10,15,20-Tetrakis(4-(α-d-mannopyranosylthio)-2,3,5,6-tetrafluorophenyl)-2,3-(methano(N-methyl)iminomethano)chlorin (H2TFPC-SMan) has been prepared and characterized by 1H and 19F NMR and UV-vis spectroscopies, MALDI-TOF mass spectrometry, and elemental analysis.

H2TFPC-SMan generates singlet oxygen (1O2) upon light irradiation. The value of the relative magnitude of the 1O2-generating ability of H2TFPC-SMan is comparable to that of 5,10,15,20-tetrakis(4-(β-d-glucopyranosylthio)-2,3,5,6-tetrafluorophenyl)-2,3-(methano(N-methyl)iminomethano)chlorin (H2TFPC-SGlc). The dark and photocytotoxicity of H2TFPC-SMan and H2TFPC-SGlc were tested in HeLa cells. These compounds showed no cytotoxicity in the dark. Upon photoirradiation, these compounds killed almost all of the cells in the region of a 1 to 2 µM concentration. The photocytotoxicity of the compounds completely disappeared in the concentration region of 0 to 0.1 µM. The photocytotoxicity of H2TFPC-SMan is significantly higher than that of H2TFPC-SGlc in the concentration range from 0.2 to less than 1 µM. The cellular uptake of H2TFPC-SMan in HeLa cells was estimated in terms of fluorescence intensity from each HeLa cell. The cellular uptake of H2TFPC-SMan is significantly higher than that of H2TFPC-SGlc at a concentration of 0.5 µM. These results are consistent with the experimental observation that the photocytotoxicity of H2TFPC-SMan is significantly higher than that of H2TFPC-SGlc in a concentration range from 0.2 to less than 1 µM.

Για τον σκοπό αυτό χρησιμοποιήθηκε ερωτηματολόγιο αυτοαναφοράς, το οποίο περιελάμβανε δύο κλίμακες μέτρησης.Τα αποτελέσματα δείχνουν ότι το 36,5% των μεταπτυχιακών φοιτητών δηλώνει ότι διακατέχεται από υψηλά επίπεδα άγχους (score>3,5), το οποίο πηγάζει κυρίως από τις γραπτές εργασίες και εξετάσεις. Επίσης, ποσοστό 39% δηλώνει αρκετά ικανοποιημένο από την υποστήριξη του καθηγητή-συμβούλου. Παρατηρήθηκε ακόμη ότι τα επίπεδα άγχους τους διαφοροποιούνται σε σχέση με το Πανεπιστήμιο φοίτησής τους, ωστόσο δεν εντοπίστηκε συσχέτιση μεταξύ των δύο βασικών εξαρτημένων μεταβλητών της έρευνας, γεγονός το οποίο καθιστά αναγκαία την αναζήτηση και άλλων παραγόντων, οι οποίοι μπορούν να συμβάλουν στη μείωση του άγχους των μεταπτυχιακών φοιτητών.

Η πλατφόρμα E-lios είναι μια νέα εκπαιδευτική πλατφόρμα που παρέχει στους εκπαιδευτικούς και τους διδάσκοντες τη δυνατότητα να δημιουργήσουν τα δικά τους εκπαιδευτικά σενάρια. Η καινοτομία του είναι ότι παρέχει ένα δομημένο πλαίσιο όπου ένας εκπαιδευτικός μπορεί να ακολουθήσει κατάλληλα βήματα ενός οδηγού πλοήγησης και να δημιουργήσει ένα εκπαιδευτικό σενάριο. Αυτά τα βήματα παρουσιάζονται ως πεδία που πρέπει να συμπληρωθούν από τον συγγραφέα ενώ στο τέλος εμφανίζονται ως ένα ολοκληρωμένο αποτέλεσμα σε μορφή έτοιμου προς διδασκαλία. Εκτός από αυτή τη δομημένη μορφή, η πλατφόρμα e-lios εισάγει δύο κύριες καινοτόμες πτυχές. Πρώτον, παρέχει το πεδίο: «ιστορίες ζωής φοιτητών» όπου οι μαθητές μπορούν να ανεβάσουν τις δικές τους ιστορίες και δεύτερον, μέσα στην ίδια φιλοσοφία, η πλατφόρμα e-lios εισάγει την καρτέλα «δεξιότητες ζωής» κυρίως για δασκάλους αλλά και ενήλικες που επιθυμούν να μοιραστούν τις εμπειρίες της ζωής τους. Αυτές οι δύο πτυχές της πλατφόρμας e-lios εισάγουν ευθέως προσωπικές εμπειρίες στη διαδικασία εκμάθησης, αναπτύσσοντας έτσι σενάρια βασισμένα στη μετασχηματιστική μάθηση. Στο πλαίσιο αυτό προτείνουμε ένα σενάριο με τίτλο: "Διδασκαλία του Ολοκαυτώματος. Μάθηση για το Άουσβιτς μέσω της τέχνης ". Αυτό το εκπαιδευτικό σενάριο πλησιάζει σε ένα μεγάλο ιστορικό γεγονός μέσω μεμονωμένων εμπειριών, που εκφράζονται από την τέχνη.

Θεωρητικές έννοιες, όπως η επικοινωνία, η συνεργασία και η αλληλεπίδραση, μεταξύ των μελών μια τάξης, συντελούν στη δημιουργία ενός εποικοδομητικού μαθησιακού πλαισίου. Η συμβολή των εννοιών αυτών σε όσους εκπαιδεύονται από απόσταση κρίνεται ακόμα πιο σημαντική, γιατί η γεωγραφική διασπορά τους και η μοναχική πορεία αυτομόρφωσής τους, μπορεί να επιτείνει αισθήματα απομόνωσης, μοναξιάς, αβεβαιότητας και ανασφάλειας. Βασικός σκοπός του παρόντος άρθρου είναι να αναδείξει, μέσα από τη βιωμένη εμπειρία των μεταπτυχιακών φοιτητών της Θεματικής Ενότητας (ΘΕ) «Ανοικτή και εξΑΕ» (ΕΠΑ65) του Ανοιχτού Πανεπιστημίου Κύπρου, πώς οι προαναφερόμενες έννοιες πραγματώνονται σε δράσεις, μέσα από τους στόχους, τη μεθοδολογική προσέγγιση, αλλά και το εκπαιδευτικό υλικό της θεματικής κατά την ακαδημαϊκή περίοδο 2016-2017. Το παρόν άρθρο διαπραγματεύεται μέσα από τη εμπειρία των φοιτητών α) τη διεπαφή των φοιτητών με το εκπαιδευτικό υλικό, β) τη σχέση μεταξύ Καθηγητή-Συμβούλου (ΚΣ) και Συντονιστή της ΘΕ και των φοιτητών, καθώς και γ) τη σχέση των φοιτητών μεταξύ τους σε συνάρτηση με τα διαφαινόμενα μαθησιακά αποτελέσματα. Η ανάδειξη βασικών εννοιών στην εξ Αποστάσεως Εκπαίδευση (εξΑΕ) μέσα από την παρούσα μελέτη περίπτωσης, από τη μια στοχεύει να προσκαλέσει τον αναγνώστη να συμβιώσει την εμπειρία αυτή και από την άλλη να προτείνει καινοτόμους μεθοδολογικούς σχεδιασμούς που «μικραίνουν» την απόσταση και «μεγαλώνουν» την επιθυμία των φοιτητών για μια αποτελεσματική μορφή μάθησης από απόσταση.

Αντικείμενο του άρθρου είναι η αξιολόγηση της αποτελεσματικότητας των επιμορφωτικών προγραμμάτων στις Τεχνολογίες Πληροφορίας και Επικοινωνίας(ΤΠΕ) για εκπαιδευτικούς.Η  έρευνα πραγματοποιήθηκε κατά το ακαδημαϊκό έτος 2015-16,  και σκοπός της ήταν να διερευνήσει τις απόψεις των φιλολόγων του Νομού Μεσσηνίας, που έχουν παρακολουθήσει επιμορφωτικά προγράμματα στις ΤΠΕ, όσον αφορά στην απόκτηση Τεχνολογικών Παιδαγωγικών Γνώσεων Περιεχομένου (ΤΠΓΠ) και στην εφαρμογή των γνώσεων αυτών στο σχολικό περιβάλλον και ιδίως στην διδακτική διαδικασία. Τα ερευνητικά ερωτήματα σχεδιάστηκαν για να ανιχνεύσουν κατά πόσο οι φιλόλογοι απέκτησαν γνώσεις ΤΠΓΠ, σε ποιο βαθμό τις χρησιμοποιούν στην καθημερινή εκπαιδευτική διαδικασία, και κατά πόσο παράγοντες όπως η ηλικία, το φύλο, το επίπεδο εκπαίδευσης και επιμόρφωσης επηρεάζουν την απόκτηση και χρήση των γνώσεων αυτών. Ακολουθήθηκε η ποσοτική προσέγγιση. Εργαλείο συλλογής δεδομένων αποτέλεσε ένα ερωτηματολόγιο με ερωτήσεις κλειστού τύπου. Στην έρευνα συμμετείχαν 91 φιλόλογοι, που υπηρετούν σε σχολεία της Διεύθυνσης της Δευτεροβάθμιας Εκπαίδευσης του Νομού Μεσσηνίας.Τα αποτελέσματα της έρευνας έδειξαν ότι σύμφωνα με τις απόψεις τους οι εκπαιδευτικοί αξιολογούν θετικά την απόκτηση γνώσεων ΤΠΓΠ από τη συμμετοχή τους σε επιμορφωτικά προγράμματα για εκπαιδευτικούς στις ΤΠΕ. Τη χρήση των ΤΠΕ επηρεάζουν παράγοντες όπως η εμπειρία τους και το επίπεδο επιμόρφωσής τους.

Τα τελευταία χρόνια αρχίζουν να εφαρμόζονται σε συνδυασμό με τις παραδοσιακές και νεότερες τεχνικές αξιολόγησης, όπως διαπιστώνει κανείς και από την εκπαιδευτική πράξη. Το ζήτημα χρήσης νέων τρόπων αξιολόγησης που προέκυψε ήταν βαρύνουσας σημασίας καθώς έγινε επιτακτική η ανάγκη βελτίωσης της αξιολόγησης της σχολικής επίδοσης και αρκετοί ήταν εκείνοι που υποστήριξαν έντονα την εξάλειψη των αδυναμιών του παραδοσιακού τρόπου αποτίμησης της προόδου των μαθητών. Οι τρόποι αυτοί είναι γνωστοί ως αυθεντικές μορφές αξιολόγησης - authentic evaluation και συνδέουν άμεσα τη μάθηση και τη διαδικασία της αξιολόγησης με ρεαλιστικές, ουσιαστικές "αυθεντικές" καταστάσεις της ζωής, εμπειρίες και βιώματα των παιδιών.Το ιδανικό θα ήταν να εφαρμόζεται στην πράξη, ανάλογα με την περίπτωση, ένας συνδυασμός παραδοσιακών και σύγχρονων μεθόδων, οι οποίες θα προσαρμόζονται κατάλληλα στις ανάγκες του εκπαιδευτικού συστήματος κάθε χώρας, το οποίο οφείλει να ανανεώνεται συνεχώς και να συμβαδίζει με την κοινωνία, την πραγματικότητα και τις διαρκώς μεταβαλλόμενες απαιτήσεις της καθημερινότητας. Κυρίως όμως οι εναλλακτικές προτάσεις και μέθοδοι καλούνται να ταιριάζουν, να εξυπηρετούν και να εστιάζουν σε μεγάλο βαθμό στις ανάγκες και το επίπεδο των παιδιών ώστε να φανερώνουν τι πραγματικά ξέρει ή μπορεί να κάνει το άτομο που αξιολογείται βάσει των γνώσεων που κατέκτησε και διαθέτει και βάσει των δεξιοτήτων που έχει αποκτήσει και καλλιεργήσει στο πλαίσιο της διδασκαλίας και της άσκησής του στο σχολικό περιβάλλον

Ένα πρόγραμμα διαγενεακής σύνδεσης δημιουργεί ευκαιρίες ομαδοσυνεργατικής και μετασχηματίζουσας μάθησης για μαθητές, παππούδες και γιαγιάδες, οι οποίοι προέρχονται από περιβάλλοντα με εντελώς διαφορετικά χαρακτηριστικά. Η ψηφιακή αφήγηση στα χέρια μαθητών γίνεται ένα εργαλείο αποτύπωσης ιστοριών αγάπης μιας άλλης εποχής και οι προφορικές αφηγήσεις μετασχηματίζονται σε ψηφιακές. Ταυτόχρονα η ψηφιακή αφήγηση λειτουργεί ως ένας υποστηρικτικός μηχανισμός αλληλεπίδρασης παλαιών και νέων οπτικών που μετασχηματίζονται σε νέα νοήματα και νέα γνώση, με τον εκπαιδευτικό σε ρόλο διευκολυντή και διασφαλιστή ποιοτικών διαδικασιών.

Η νέα κοινωνική πραγματικότητα οδηγεί στην ανάγκη καλλιέργειας υψηλού επιπέδου δεξιοτήτων, έτσι ώστε οι πολίτες να μπορούν να προσεγγίσουν τα πολυδιάστατα προβλήματα και να δώσουν λύσεις αξιοποιώντας τη δημιουργικότητα, την αφαιρετική σκέψη και την εναλλακτική θέαση των πραγμάτων. Το εργαστήριο Δια βίου και Εξ Αποστάσεως Εκπαίδευσης του Παιδαγωγικού Τμήματος του Πανεπιστημίου Κρήτης, ανταποκρινόμενο στις σύγχρονες επιμορφωτικές  ανάγκες των εκπαιδευτικών, υλοποιεί από το 2013 εξ αποστάσεως προγράμματα επιμόρφωσης με θέμα «Η Αξιοποίηση του web 2.0 στο Σύγχρονο Σχολείο - Από τη Θεωρία στην Πράξη με έμφαση στη Συνεργασία, τη Δημιουργικότητα και την Κριτική Σκέψη», τα οποία απευθύνονται σε εκπαιδευτικούς Πρωτοβάθμιας Εκπαίδευσης και απόφοιτους Παιδαγωγικών Τμημάτων Δ.Ε. Σκοπός της παρούσας εργασίας είναι η διερεύνηση του τρόπου αξιοποίησης των εφαρμογών Web 2.0 στην επιμόρφωση των εκπαιδευτικών, με έμφαση στην ανάπτυξη της δημιουργικότητας των επιμορφούμενων.
Ο "λόγος" μελών Δ.Ε.Π. του ΕΑΠ για την παροχή εξ αποστάσεως εκπαίδευσης με τη χρήση των MOOCs: Παιδαγωγικοί ρόλοι και αλληλεπίδραση μεταξύ διδάσκοντα - διδασκόμενων

Σε αυτή την διεπιστημονικού χαρακτήρα εργασία επιχειρείται με την αξιοποίηση κοινωνιολογικών θεωρητικών εργαλείων η προσέγγιση του λόγου των μελών Διδακτικού και Ερευνητικού Προσωπικού (Δ.Ε.Π.) του Ελληνικού Ανοικτού Πανεπιστημίου (ΕΑΠ) για τη διαμόρφωση των παιδαγωγικών ρόλων και την αλληλεπίδραση μεταξύ διδάσκοντα και διδασκόμενων στην περίπτωση υιοθέτησης των MOOCs για την παροχή ανοικτής και εξ αποστάσεως εκπαίδευσης από το ίδρυμα. Πρόκειται για μια ποιοτικού χαρακτήρα μελέτη στην οποία συμμετείχαν μέλη Δ.Ε.Π. του ΕΑΠ, που διαθέτουν το απαραίτητο επιστημονικό κεφάλαιο για να εκφράσουν έγκυρη γνώμη για τα εξεταζόμενα ζητήματα. Τα κυριότερα ευρήματα της έρευνας αυτής έδειξαν ότι θα πρέπει να γίνουν προσαρμογές στους ρόλους του διδάσκοντα και του διδασκόμενου εφόσον το ΕΑΠ προσφέρει μαθήματα τύπου MOOCs. Επίσης, με τα MOOCs δεν θα υπάρξει ουσιαστική αλληλεπίδραση μεταξύ καθηγητή και φοιτητών, ενώ και η αλληλεπίδραση μεταξύ των φοιτητών θα προκύψει εάν οι ίδιοι αυτενεργήσουν και αξιοποιήσουν τα forα και τα μέσα κοινωνικής δικτύωσης για να επικοινωνήσουν μεταξύ τους για λόγους αλληλοϋποστήριξης και αλληλοβοήθειας. Τέλος, το σημαντικότερο πλεονέκτημα για τους διδάσκοντες που θα διδάξουν σε MOOCs θα είναι ότι θα γίνουν περισσότερο αναγνωρίσιμοι από τους πολίτες, ενώ πλεονέκτημα για τους διδασκόμενους θα είναι η πραγματική εφαρμογή του ιδεώδους της ανοικτότητας στο ΕΑΠ.
Liquid chromatography–tandem mass spectrometry for the simultaneous quantitation of ceftriaxone, metronidazole and hydroxymetronidazole in plasma from seriously ill, severely malnourished children

Published: January 2018

We have developed and validated a novel, sensitive, selective and reproducible reversed-phase high-performance liquid chromatography method coupled with electrospray ionization mass spectrometry (HPLC–ESI-MS/MS) for the simultaneous quantitation of ceftriaxone (CEF), metronidazole (MET) and hydroxymetronidazole (MET-OH) from only 50 µL of human plasma, and unbound CEF from 25 µL plasma ultra-filtrate to evaluate the effect of protein binding. Cefuroxime axetil (CEFU) was used as an internal standard (IS). The analytes were extracted by a protein precipitation procedure with acetonitrile and separated on a reversed-phase Polaris 5 C18-Analytical column using a mobile phase composed of acetonitrile containing 0.1% (v/v) formic acid and 10 mM aqueous ammonium formate pH 2.5, delivered at a flow-rate of 300 µL/min. Multiple reaction monitoring was performed in the positive ion mode using the transitions m/z555.1→m/z396.0 (CEF), m/z172.2→m/z 128.2 (MET), m/z188.0→m/z125.9 (MET-OH) and m/z528.1→m/z 364.0 (CEFU) to quantify the drugs. Calibration curves in spiked plasma and ultra-filtrate were linear (r2 ≥ 0.9948) from 0.4–300 µg/mL for CEF, 0.05–50 µg/mL for MET and 0.02 – 30 µg/mL for MET-OH. The intra- and inter- assay precisions were less than 9% and the mean extraction recoveries were 94.0% (CEF), 98.2% (MET), 99.6% (MET-OH) and 104.6% (CEF in ultra-filtrate); the recoveries for the IS were 93.8% (in plasma) and 97.6% (in ultra-filtrate). The validated method was successfully applied to a pharmacokinetic study of CEF, MET and MET-OH in hospitalized children with complicated severe acute malnutrition following an oral administration of MET and intravenous administration of CEF over the course of 72 hours.
The Gay Market is Dead, Long Live the Gay Market: From Identity to Algorithm in Predicting Consumer Behavior
Authors: Sender Katherine
Published: January 2018

Abstract: Target marketing to identity-based consumer niches such as gay men and lesbians (occasionally bisexuals, transgender and queer people) has been radically transformed since 2000 by social media, the decline of gay and lesbian print publications, and Big Data. Drawing from 53 articles from the business and advertising trade press, this article argues that marketers no longer use sexuality-based identity markets such as "the gay market" as the primary mechanism to structure their advertising appeals. Instead, marketers collect large amounts of search, locative, and social behavior information to predict consumer behavior. If a modern LGBTQ identity was formed in part by gay and lesbian commercial media and marketing, how must we rethink queer identities in an algorithmic age of target marketing?
Female Representation among Advertising's Creative Elite: A Content Analysis of the Communication Arts Advertising Annual
Authors: Mallia Karen L. , Windels Kasey
Published: January 2018

Abstract: This study examined issues of the Communication Arts Advertising Annual in 1984, 1994, 2004, and 2014 to assess women's inclusion among award winners, which represent the upper echelons of the advertising industry's creative ranks. Findings showed that women have token status, as they represented 7% of all creative award winners in 1984, 11% in 1994, 6% in 2004, and 11% in 2014. Creative women in advertising have not made much progress toward equity in the past 30 years. This has implications for the ads that get made, the culture of the agency creative department, and the career prospects of advertising students. This also demonstrates a continuing disconnect between female consumers and the agency personnel developing the advertising targeting them.

Published: January 2018

Abstract: In Part I of the Roundtable on Social Media and Advertising, academic and industry participants met in San Francisco to discuss where, how, and why social media have become central to advertisers' work in the last fifteen years. Participants agreed that social media connect brands with everyday people. Further, when pressed to consider advertising's older forms of selling products and services, it was acknowledged that social connections have always played a role. However, many practitioners stressed that what is new is the reach and speed of such social relationships through various digital technologies like social media. For some participants, social media have made brands more transparent and responsible in how they treat the environment and their customers, employees, and communities. Although what makes an authentic relationship between companies and everyday people was debated, there was a consensus that social media make brands come to life for individuals, and that such connections seek to make companies more relatable and relevant, and, therefore, more profitable.

Published: January 2018

O presente trabalho tem como proposta avaliar a relação do nível de atividade física sobre o desempenho cognitivo em crianças. A base deste estudo é descritiva, experimental de campo sob uma perspectiva quantitativa. A população do estudo foi composta por estudantes do 3º ano do ensino fundamental em uma escola do município de Juazeiro do Norte-CE, e amostra por 96 escolares, divididos em dois grupos, Grupo A controle e Grupo B experimental. Foram realizados o teste de trilha e o questionário internacional de atividade física para crianças e adolescentes, bem como um programa de atividade física com duração de 12 semanas, sendo uma aula por semana com duração de 50’ minutos com os estudantes do Grupo B. Os resultados para o nível de atividade física dos escolares no Grupo A, 22,73% foram classificados como Ativos, 68,18% Inadequadamente Ativos e 9,09% Inativos, para o Grupo B, 19,23% são Ativos, 69,23% Inadequadamente Ativos e 11,54% Inativos. Em ambas as partes do TMT e ambos os grupos, os sujeitos do sexo masculinos obtiveram média de tempo de conclusão dos testes maior em relação ao sexo feminino. Para analise entre os grupos podemos perceber que no TMT-A a média geral do GA em relação ao tempo de execução do teste foi de 91,69 segundos e o GB de 90,36 segundos; no TMT-B o grupo GA obteve média geral de 217,58 segundos e o GB de 208,50 segundos, não encontrando significância entre os grupos, onde no TMT-A com p=0,93 e TMT-B com p=0,74. Em relação a erro cometido durante o teste no TMT-A a média geral do GA foi de 2,12 e o GB de 2,68 erros e no TMT-B a média geral de erro do GA foi de 3,77 e GB de 4,36 erros. Também não foram encontrados valores de significância para essa variável onde p=0,42 no TMT-A e p=0,43 no TMT-B. Após análise dos dados pode-se perceber que faz-se necessário que além das práticas de atividade física no ambiente escolar, as crianças devem participar de outras atividades físicas em seus momentos de lazer para que tenham um desenvolvimento cognitivo melhorado, como também que seja realizado estimulado externo no convívio familiar e social da criança.

Authors: Silva Débora Dos Santos , Gomes Cícera Maria Dos Santos , Marinho Ana Olívia De Oliveira
Published: January 2018

O termo afefobia representa aqueles que sentem uma forte angústia com sintomas de taquicardia, sudorese, sensação de punhalada no peito, náusea e tremores quando tocados. Estes sintomas podem variar de pessoa para pessoa, sendo que algumas podem senti-los até em contatos/toques sociais: como um simples aperto de mão. A evitação fóbica tende a ficar evidente na idade adulta quando as pessoas geralmente elegem um objeto amoroso. Tende a surgir com intenso sofrimento psíquico a depender de cada história de vida e da estruturação clínica. Para abordar o tema, utilizou-se o recurso do estudo de caso, onde foi feito a descrição e análise da personagem principal do filme Repulsão, Carole Ledoux, no intuito de vislumbrar e melhor entender, a partir da ficção e norteada pela psicanálise, um assunto que causa bastante sofrimento em quem padece desta problemática afetiva. Conclui-se sinalizando a importância da associação livre, da fala em análise, para que se possa lidar com os afetos e possibilitar, por acréscimo, a cura de sintomas que causem adoecimento. Palavras-chave: Afefobia; Carole Ledoux; Amor; Loucura; Associação Livre.

Islam is called the religion of green because it has a high attention to environmental sustainability. In the Qur’an many verses concerning the preservation of theenvironment are called green verses. The naming of suras in the Qur’an: Al- Baqarah, An-Naml, An-Nahl, Al-Ankabut using the names of animals. Then thereare many hadiths that recommend humanity to maintain the nature, maintain good environment of plants, and animals. The hadith can be called by the green hadith. The concept of Islam as a green religion can be used in the integration of integrated thematic learning. In this paper the integration is designed for class 1 theme 7:Benda, Hewan dan Tanaman di Sekitarku. In Subtema 2: the readings of “Binatang Peliharaan Beni” and the reading of “Tempat Tinggal Hewan” are very much aligned with the concept of Islam as a green religion. Similarly for subtheme 3 with the reading “Merawat Tanaman” fits perfectly with the concept of Islam as a green religion. Mathematical learning with thematic lessons based on the concept of green religion Islam can use fruits, grains and perform short length measurements using trees and parts.Keywords: Islam as a green religion, thematic learning, green verses, green hadith

Strategic Effects between Price-takers and Non-price-takers
Authors: Hirth Hans , Walther Martin
Published: January 2018

Price-taking behavior seems to contradict rationality if a price effect is to be expected. This paper identifies a strategic effect between price-takers and non-price-takers on financial markets. It results from the liquidity reduction non-price-taking induces. Thus, a trade-off between the benefits of calculating price impacts correctly and market liquidity exists. It is shown that price-takers may benefit more from trading than their fully rational counterparts do. Moreover, it is demonstrated that when the choice of behavior is unobservable and decision costs exist an investor would profit more as a non-price-taker when his trading potential is large, and more as a price-taker when it is small. However, when the choice of behavior is observable it is the other way around. If various rounds of trading take place, an investor’s terminal endowment converges to his risk tolerance share. Thus, an efficient allocation is obtained. Furthermore, a paradox concerning the endogenous choice of manners of calculation is identified.
