Ανοστοϊστοχημική εκτίμηση πρωτεϊνών οξείας φάσης σε διηθητικά καρκινώματα μαστού
Authors: Δήμας Διονύσιος
Published: August 2021

Σκοπός της παρούσας μελέτης είναι η αξιολόγηση της σημασίας της έκφρασης των Hsp70/90 σε ασθενείς με καρκίνο μαστού. Σημαντική προέκταση της εκτίμησης αυτής αποτελεί η αξιολόγηση της σημασίας τους ως δυνητικά μόρια-στόχους στη φαρμακευτική θεραπεία του καρκίνου του μαστού.Μέθοδος: Προκειμένου για την αξιολόγηση της σχέσης αυτής πραγματοποιήθηκε μελέτη σε ιστικά δείγματα από 54 ασθενείς με πορογενή νεοπλάσματα του μαστού. Χρησιμοποιήθηκαν τα κατάλληλα αντιδραστήρια για τη μελέτη της έκφρασης των Hsp70/90 στα δείγματα αυτά, καθώς και της έκφρασης των ER, PR, HER2, Ki67. Παράλληλα εξετάστηκε, η διαφορά έκφρασης μεταξύ καρκινικών και μη ιστών, ο βαθμός ιστολογικής κακοήθειας, το μέγεθος του όγκου, η παρουσία ή μη λεμφαδενικής διήθησης από τον όγκο και η παρουσία απομακρυσμένων μεταστάσεων. Κατόπιν πραγματοποιήθηκε συστηματική ανασκόπηση της βιβλιογραφίας προκειμένου για τον έλεγχο της επίδρασης της έκφρασης των Hsp70/90 στην επιβίωση, το PCNALI, καθώς και στις μεταβλητές που εξετάστηκαν στην πρωτογενή μελέτη της παρούσας διατριβής. Επίσης πραγματοποιήθηκε ποσοτική σύνθεση (μετα-ανάλυση) των σχετικών αποτελεσμάτων των μελετών που περιλήφθηκαν στην ανασκόπηση.Αποτελέσματα: Από τις μεταβλητές που εξετάστηκαν στην πρωτογενή μελέτη δεν προέκυψε κάποια στατιστικά σημαντική συσχέτιση μεταξύ αυτών και της έκφρασης των Hsp70/90. Μόνη εξαίρεση αποτελεί η στατιστικά σημαντική, χαμηλότερη έκφραση της Hsp90 στο IDC (Invasive Ductal Carcinoma) σε σχέση με αυτή στο DCIS (Ductal Carcinoma in Situ) (DCIS (6.54±1.31 vs. 7.16±0.82, αντίστοιχα, p=0.004, Wilcoxon matched-pairs signed-ranks test) και αντίστοιχα, η σημαντικά χαμηλότερη έκφρασή της στο DCIS σε σχέση με αυτήν στο φυσιολογικό παρακείμενο μαστό (p=0.0002, με την ίδια δοκιμασία). Από την συστηματική ανασκόπηση της βιβλιογραφίας, τα μόνα σημεία στα οποία υπήρχε σύμπνοια των αποτελεσμάτων των μελετών, αφορούσαν στην έκφραση της Hsp70 σε σχέση με το PCNALI και στην σημαντικά χειρότερη συνολική επιβίωση των ασθενών με υψηλή έκφραση της Hsp90. Από τη μετα-ανάλυση προέκυψε συσχέτιση της υψηλής έκφρασης της Hsp90 με χειρότερη συνολική επιβίωση και οριακά χειρότερη ελεύθερη-νόσου επιβίωση των ασθενών με καρκίνο μαστού. Η υψηλή έκφραση της Hsp70 συσχετίστηκε επίσης με χειρότερη ελεύθερη-νόσου επιβίωση, καθώς και θετικότητα των οιστρογονικών (ER) και προγεστερονικών (PR) υποδοχέων.Συμπέρασμα: Από τη συστηματική ανασκόπηση και μετα-ανάλυση που πραγματοποιήθηκε στα πλαίσια της παρούσας διατριβής, υπογραμμίζεται η προγνωστική αξία της έκφρασης των Hsp70 και Hsp90 στον καρκίνο του μαστού. Περαιτέρω υψηλής ποιότητας μελέτες, με αναλυτική παρουσίαση των αποτελεσμάτων τους είναι αναγκαίες για την παροχή επιδημιολογικών στοιχείων, που θα συμπληρώσουν τα ευρήματα των εν εξελίξει κλινικών δοκιμών για τους αναστολείς των Hsps.

Πειραματική επιμορφωτική παρέμβαση σε εκπαιδευτικούς της πράξης στο αντικείμενο της εκτίμησης
Authors: Μουράτογλου Αναστασία
Published: August 2021

Τις τελευταίες δεκαετίες έχουν πραγματοποιηθεί αρκετές έρευνες στον χώρο της διδακτικής των μαθηματικών που αφορούν το αντικείμενο της εκτίμησης. Λίγες όμως είναι αυτές που αφορούν διδακτικές παρεμβάσεις και μάλιστα επιμορφωτικές παρεμβάσεις σε εκπαιδευτικούς. H παρούσα εργασία στοχεύει στη μελέτη και στη σύγκριση των παραγόντων που καθορίζουν τη μεταβολή της συμπεριφοράς 11 εν ενεργεία Ελλήνων εκπαιδευτικών της πρωτοβάθμιας εκπαίδευσης μετά από μια επιμορφωτική παρέμβαση στις εκτιμήσεις. Οι παράγοντες που τέθηκαν στην έρευνα αυτή για να μετρήσουν την αλλαγή στη συμπεριφορά των εκπαιδευτικών αφορούσαν τόσο τα γνωστικά, όσο και τα προσωπικά χαρακτηριστικά τους. Στην πρώτη κατηγορία ανήκαν: η ικανότητα διατύπωσης του ορισμού της εκτίμησης, η γνώση του περιεχομένου, η παιδαγωγική γνώση του περιεχομένου με βάση ευρήματα από ερωτηματολόγια, η παιδαγωγική γνώση του περιεχομένου με βάση την παρατήρηση της διδακτικής τους πράξης, η χρήση των στρατηγικών εκτίμησης και η επίδοση των μαθητών τους σε προβλήματα εκτίμησης. Στη δεύτερη κατηγορία ανήκαν: η ηλικία, ο προσανατολισμός τους ως προς τα μαθηματικά (βάση των σπουδών στο Λύκειο) και τα χρόνια προϋπηρεσίας των εκπαιδευτικών. Τα αποτελέσματα έδειξαν ότι παράγοντες όπως η ικανότητα διατύπωσης του ορισμού της εκτίμησης δεν σχετίζεται με κανέναν από τους άλλους παράγοντες. Ωστόσο η επίδοση των μαθητών φαίνεται να επηρεάζεται κυρίως από τον τρόπο που γίνεται η διδασκαλία στην τάξη. Μία ακόμη συσχέτιση που διαπιστώνεται στην παρούσα εργασία είναι αυτή μεταξύ της γνώσης του περιεχομένου και της χρήσης των στρατηγικών εκτίμησης. Επίσης, άξιο αναφοράς είναι το γεγονός ότι τα αποτελέσματα της Π.Γ.Π. διαφέρουν και δε συσχετίζονται μεταξύ τους όταν η εξέταση γίνεται με ερωτηματολόγια από όταν γίνεται με παρατήρηση της διδακτικής πράξης. Το αποτέλεσμα αυτό θέτει ερωτήματα ως προς την εγκυρότητα της εξέτασης της Π.Γ.Π. μέσω ερωτηματολογίων. Τέλος, διαπιστώνεται ότι η διδασκαλία των εκπαιδευτικών επηρεάζεται και από προσωπικούς παράγοντες, πέρα από τους γνωστικούς.
„Die Sprache hat also ihren Ort.“ Zur Mehrsprachigkeit von Maja Haderlaps Roman Engel des Vergessens
Authors: Neidlinger Dieter , Pasewalck Silke
Published: August 2021

“Die Sprache hat also ihren Ort.” On Multilingualism in Maja Haderlap’s Novel Engel des Vergessens. Based on philological research on multilingualism and with regard to Maja Haderlap’s literary work in general this article deals with the specific form of multilingualism that can be observed in her novel Engel des Vergessens (2011). Maja Haderlap, born 1961 in Bad Eisenkappel/Železna Kapla, Carinthia (region in southern Austria), grew up with two languages, Slovenian and German. The authors of the article pursue the question to what degree her literary work and especially her novel can be characterised as multilingual and what kind of poetic multilingualism can be found there. They focus on the novel’s narrative and on the use of language(s), with a short historical excursus on the Slovenian minority in Carinthia as well as the difficult memory politics in Austria. Maja Haderlap not only writes about the territorial and historical preconditions of multilingualism in Carinthia but also inscribes these conditions in the text itself, characterising both the narrative and the language. Although the novel is the result of a shift from Slovenian to German, its multilingualism can be analysed on different levels: on the level of the relationship between discours and histoire – to refer to Genette’s narratological terms –, on the level of cultural codes of the Slovenian language within the novel’s German text, and in general with regard to the fact, that the text is written with the modes of expression of Slovenian and German or with the help of the ‘no man’s land’ between the languages. One can therefore – with respect to the terms of philological research – find both obvious and latent multilingualism and, thirdly, one can observe Mehr-Sprachlichkeit, a term that has been defined by Silke Pasewalck in previous articles.
Mehrsprachigkeit in der Bildung in Deutschland – eine Diskursanalyse
Authors: Engels Farin
Published: August 2021

Multilingualism in Education in Germany – a Discourse Analysis. In the Republic of Germany, language acquisition for children with a mother tongue other than German has been a widely discussed topic in education science as well as in public and political discourse over the last decades. Annual studies on preschool and primary education point to the ongoing disadvantage – or even discrimination – suffered by multilingual children in the German education system. Given Germany’s history as a country of immigration, and in light of recent public discussions on the increased immigration of refugees, the question of the problematic’s socio-political background arises. This leads to the issue of linguistic concepts among society and their influence on domestic language policies. This article presents analysis of discourse around languagepolitical concepts and practices among stakeholders in language promotion in the state of North-Rhine Westphalia. Five semi-structured interviews with state employees were analysed following a discourse analytical approach. The analysis, deploying frameworks from the field of Critical Discourse Analysis, focused on the discursive practice of legitimation in the evaluation of multilingualism. Multilingualism as a phenomenon in society appeared to be evaluated according to differing standards (for example correctness or properness) depending on the language. As for evaluation, the analysis indicated an additional dimension in discourse which assigns different groups of speakers a belonging to particular languages. All in all, the collected data pointed to a diverse and ever-changing discourse in the field of language promotion in North-Rhine Westphalia. The presented analysis aims to stimulate a debate and suggests some directions for future research.
Heute sprechen. Literatur, Politik und andere Sprachen im Lied (Herder, Alunāns, Barons)
Authors: Dembeck Till
Published: August 2021

Speaking Today. Literature, Politics and Other Languages in Songs (Herder, Alunāns, Barons). This article claims that the politico-cultural relevance of literary texts in their respective present consists, among other aspects, of their handling of linguistic diversity. As examples, it presents three 18th and 19th century publications from the German and/or Latvian speaking territories which put (folk) songs into the centre of their rather different politicocultural endeavours. Herder’s collection of folk songs from 1778/79 is read as an attempt at a poetic new beginning that makes use of linguistic diversity qua translation in order to inspire originality in the ‘mother tongue’. The folk songs here serve to synchronise and dynamise linguistic means in the name of a new literature. The Dseesmiņas (‘little songs’), a collection of translations of European poetry into Latvian published by Alunāns in 1856, combines precisely this claim to renewal with an attempt at an anti-colonial synchronisation and modernisation of the Latvian language. Eventually, the six-volume collection of Latwju Dainas (Latvian folk songs), published by Barons around 1900, takes up Herder’s efforts to preserve folk songs. Barons synchronises a dialectally, materially and historically diverse corpus of songs in the name of anti-colonial emancipation. In terms of cultural policy, his project aims to give presence to pre-modern folk life under the conditions of modernity.
Towards the Peculiarities of Jean-Luc Melenchon’s Idiolecte
Authors: Loginova Polina
Published: August 2021

The paper presents the analysis of the peculiarities of the verbal behaviour of the French politician Jean-Luc Mélenchon. On the examples obtained from his interviews and videos, the author demonstrates that by means of such figures of speech as metaphors and phraseological units, the French politician was able to materialize his persuasive strategies by manipulating people’s minds. It is emphasized that metaphoric expressions used within the idiolect of Jean-Luc Mélenchon were able to form positive or negative image and perception of the politician, therefore the role of these figures of speech cannot be underestimated.

It is also observed that the study of metaphors is considered to be extremely important within the learning process at the University, especially when teaching the language of French political communication to students in Political Science, International Journalism and Diplomacy.
Choice-Based Dynamic Pricing for Vacation Rentals
Authors: Wang Yaping , McGuire Kelly , Terbush Jeremy , Towns Michael , Anderson Chris K.
Published: August 2021

In this paper, we propose a new dynamic pricing approach for the vacation rental revenue management problem. The proposed approach is based on a conditional logistic regression that predicts the purchasing probability for rental units as a function of various factors, such as lead time, availability, property features, and market selling prices. In order to estimate the price sensitivity throughout the booking horizon, a rolling window technique is provided to smooth the impact over time and build a consistent estimation. We apply a nonlinear optimization algorithm to determine optimal prices to maximize the revenue, considering current demand, availability from both the rental company and its competitors, and the price sensitivity of the rental guest. A booking curve heuristic is used to align the booking pace with business targets and feed the adjustments back into the optimization routine. We illustrate the proposed approach by successfully applying it to the revenue management problem of Wyndham Destinations vacation rentals. Model performance is evaluated by pricing two regions within the Wyndham network for part of the 2018 vacation season, indicating revenue per unit growth of 3.5% and 5.2% (for the two regions) through model use.
Blockchain-Based Access Control and Data Sharing Mechanism in Cloud Decentralized Storage System
Authors: Gajmal Yogesh M , Udayakumar R.
Published: August 2021

Access control is a major factor in enhancing data security in the cloud storage system. However, the existing data sharing and the access control method have privacy data leakage and key abuse, which is a major challenge in the research community. Therefore, an effective method named Blockchain-based access control and data sharing approach is developed in the cloud storage system to increase data security. The proposed Blockchain-based access control and data sharing approach effectively solve single-point failure in the cloud system. It provides more benefits by increasing the throughput and reducing the cost. The Data user (DU) makes the registration request using the ID and password and forwards it to the Data Owner (DO), which processes the request and authenticates the Data user. The information of the data owner is embedded in the transactional blockchain using the encrypted master key. The Data owner achieves the data encryption process, and encrypted files are uploaded to the Interplanetary File System (IPFS). Based on the encrypted file location and encrypted key, the Data owner generates the ciphertext metadata and is embedded in the transactional blockchain. The proposed Blockchain-based access control and data sharing approach achieved better performance using the metrics, like a better genuine user detection rate of 95% and lower responsiveness of 25sec with the blockchain of 100 sizes.

Effects of a Self-Advocacy Intervention on Abilities of Black College Students With Intellectual and Developmental Disabilities to Request Academic Accommodations
Authors: Brendli Katherine R. , Scott LaRon A. , Xu Yaoying , Thoma Colleen , Holzberg Debra
Published: August 2021

Several barriers exist that inhibit the success of students with disabilities in postsecondary education environments, one of which is the lack of self-advocacy skills to effectively request academic modifications and ask for other supports when needed. In this study, we used a single-subject multiple-probe across participants design to examine the effects of a self-advocacy intervention on the abilities of college students with intellectual and developmental disabilities (IDD) to request their academic accommodations. We primarily focused the intervention on Black youth with IDD attending an inclusive higher education program. Results indicate moderate to strong evidence of a functional relation between the intervention and the students' abilities to request academic accommodations. Implications for future research, policy, and practice are discussed.

When it comes to visceral leishmaniasis (VL) in Brazil, one of the main targets of public health policies of surveillance is the control of domestic canine reservoirs of Leishmania infantum. This paper aims to evaluate the effect of the dog population and household environment for the maintenance of natural foci in the transmission to human and animal hosts in an endemic city for VL, Bauru, in Brazil. We collected 6,578 blood samples of dogs living in 3,916 households from Nov.2019 to Mar.2020 and applied geospatial models to predict the disease risk based on the canine population. We used Kernel density estimation, cluster analysis, geostatistics, and Generalized Additive Models (GAM). To validate our models, we used cross-validation and created a receiver operating characteristic (ROC) curve. We found an overall canine VL (CVL) seroprevalence of 5.6% for the sampled dogs, while for the households, the positivity rate was 8.7%. Odds ratios (OR) for CVL increased progressively according to the number of canines for >2 dogs (OR 2.70); households that already had CVL in the past increased the chances for CVL currently (OR 2.73); and the cases of CVL increase the chances for human VL cases (OR 1.16). Our models were statistically significant and demonstrated a spatial association between canine and human disease cases, mainly in VL foci that remain endemic. Although the Kernel density ratio map had the best performance (AUC = 82), all the models showed high risk in the city’s northwest area. Canine population dynamics must be considered in public policies, and geospatial methods may help target priority areas and planning VL surveillance in low and middle-income countries.
A general method for estimating the prevalence of influenza-like-symptoms with Wikipedia data
Authors: De Toni Giovanni , Consonni Cristian , Montresor Alberto
Published: August 2021

Influenza is an acute respiratory seasonal disease that affects millions of people worldwide and causes thousands of deaths in Europe alone. Estimating in a fast and reliable way the impact of an illness on a given country is essential to plan and organize effective countermeasures, which is now possible by leveraging unconventional data sources like web searches and visits. In this study, we show the feasibility of exploiting machine learning models and information about Wikipedia’s page views of a selected group of articles to obtain accurate estimates of influenza-like illnesses incidence in four European countries: Italy, Germany, Belgium, and the Netherlands. We propose a novel language-agnostic method, based on two algorithms,Personalized PageRankandCycleRank, to automatically select the most relevant Wikipedia pages to be monitored without the need for expert supervision. We then show how our model can reach state-of-the-art results by comparing it with previous solutions.

El presente estudio analiza una serie de sucesos y testimonios históricos relacionados con Legio y la legio VII Gemina que buscan comprender cómo Legio llega a ser un centro urbano en el pleno sentido, alcanzando incluso el rango de civitas. Para ello, llevamos a cabo un estudio sobre la posible capitalidad de Legio en la Hispania Nova Citerior Antoniniana y, a causa de ello, también de dicha provincia. Asimismo, analizamos la importancia de las lápidas epigráficas AE 1967, 225 y AE 1992, 1003, como indicios de un probable otorgamiento del estatuto municipal. Sobre esta base, realizamos una reinterpretación de la carta 67 de Cipriano de Cartago.
Pisístrato y el episodio del carro de Atenea. Nueva propuesta de datación
Authors: Iriarte Unai
Published: August 2021

El episodio de Pisístrato volviendo en un carro junto a Atenea es uno de los acontecimientos mejor conocidos del período griego arcaico. Siguiendo sobre todo a Heródoto y a Aristóteles, la historiografía moderna actual lo sitúa tras su primer exilio y antes de la consecución de su segunda tiranía. Esta consideración plantea una serie de problemas, como el papel de Atenea en un acuerdo prenupcial. Por ello, a través de un estudio pormenorizado de las fuentes, así como del contexto histórico, proponemos aplazar esta entrada teatralizada al 546, cuando se produce la batalla de Palene y poco antes de que Pisístrato se instaure como tirano por tercera y última vez. Esta nueva cronología asienta mejor algunas interpretaciones que se han venido dando, pero también permite, a su vez, novedosas lecturas sobre los medios de legitimación religiosos y sociales empleados por el tirano de Atenas.

Short range radar (SRR) uses the K-band frequency range in its application. The radar requires high-resolution, so the applied frequency is 1 GHz wide. The filter is one of the devices used to ensure only a predetermined frequency is received by the radar system. This device must have a wide operating bandwidth to meet the specification of the radar. In this paper, a band pass filter (BPF) is proposed. It is designed and fabricated on RO4003C substrate using the substrate integrated waveguide (SIW) technique, results in a wide bandwidth at the K-band frequency that centered at 24 GHz. Besides the bandwidth analysis, the analysis of the insertion loss, the return loss, and the dimension are also reported. The simulated results of the bandpass filter are: VSWR of 1.0308, a return loss of -36.9344 dB, and an insertion loss of -0.6695 dB. The measurement results show that the design obtains a VSWR of 2.067, a return loss of -8.136 dB, and an insertion loss of -4.316  dB. While, it is obtained that the bandwidth is reduced by about 50% compared with the simulation. The result differences between simulation and measurement are mainly due to the imperfect fabrication process.
Performance Evaluation of DSRC-Zigbee Heterogeneous Network for Intelligent Transportation System
Authors: Hariyadi Randi Eriko , Endroyono E. , Affandi Achmad
Published: August 2021

Transportation is one of the primary needs of human beings that cannot be avoided, with the increasing vehicle can lead to a congested road situation which can lead to less safe road safety. An Intelligent Transportation System (ITS) can be used to increase road safety. This system uses a Dedicated Short-Range Communication (DSRC) protocol for network access due to its low latency transmission time. Unfortunately, there is research shows that DSRC has a performance issue in a dense area or increased network load. This problem is mostly solved with a heterogeneous network DSRC-LTE but utilizes mobile phone networks that dynamically change can lead to inconsistent and unpredictable network performance. There is some research about ZigBee for ITS shows that it is decent enough for non-critical applications.  Thus, the authors try to utilize Zigbee to create the DSRC-Zigbee heterogeneous network so that the network is independent for the ITS application. The proposed heterogeneous network is a fixed model due to its simple architecture. OMNeT++ and Simulation of Urban Mobility (SUMO) are used to evaluate the performance of the network in an urban area with various scenarios. The simulation result shows that the proposed heterogeneous network is capable to improve the messages dissemination rate by 15.78% and 1.22% in a certain scenario compared to the homogeneous network DSRC only.

“Pois não tem de quem se valer senão de Vossa Majestade que é mãe das órfãs pobres honradas”
Authors: Braga Paulo Drumond
Published: August 2021

Neste artigo, estudam-se alguns pedidos de esmola dirigidos em 1789 a D. Maria I, rainha de Portugal. Entre as diversas formas que os pobres tinham, na época, de obter auxílio, encontrava-se a solicitação, por escrito, de uma esmola, quer a Misericórdias, quer a outras confrarias, quer a particulares poderosos, nomeadamente membros da família real. Esses pedidos eram frequentemente atendidos positivamente, uma vez que a ajuda aos desvalidos da fortuna integrava o arquétipo do bom cristão da época e, por outro lado, visava, por parte de quem esmolava, alcançar a vida eterna, surgindo a caridade e a assistência como complementos de outras formas de intercessão salvífica, nomeadamente a celebração de missas e a instituição de capelas.

O objetivo principal deste trabalho é o de investigar as lutas e as conquistas da mulher por direitos importantes, como aqueles que lhe conferiram espaço e certo reconhecimento, principalmente nos campos social, político e cultural. Para tal, considerou-se relevante abordar a gênese da desigualdade entre homens e mulheres, bem como a centralidade dos movimentos feministas na trajetória de luta da mulher em busca de seus direitos. A pesquisa em questão se utiliza do método materialista histórico e é de natureza predominantemente bibliográfica. Evidenciou-se que, durante o desenrolar da história, os movimentos sob a liderança feminina proporcionaram conquistas usufruídas pela mulher contemporânea. Dessa maneira, ao passo que se afirmam como cidadãs e sujeitos de direito, as mulheres modernas podem lutar por novos objetivos. Destaca-se, pois, que tais lutas se travam, inclusive e especialmente, em Goiás.

As mulheres e a doença
Authors: Esteves Alexandra
Published: August 2021

Em Portugal, não abundam os trabalhos, no âmbito da história das mulheres, sobre as doenças específicas do sexo feminino, embora o parto e os riscos que lhe são inerentes estejam muito presentes na literatura médica, designadamente nos séculos XVIII e XIX. Sem haver a pretensão de colmatar essa lacuna, pretendemos, com o presente artigo, dar a conhecer, entre outros aspetos, as enfermidades que mais afetavam a mulher em diferentes contextos, o modo como a sociedade e a medicina encaravam a condição feminina e era justificada a pretensa inferioridade da mulher face ao sexo masculino, que terapias eram usadas para combater os males de que padeciam, que produtos e processos usados para a prática do aborto. Para a consecução dos objetivos estabelecidos, recorremos, essencialmente, à literatura médica e a estudos que versam sobre a temática que constitui objeto do nosso trabalho.

A Nupcialidade no Reinado de D. José I (1750-1777)
Authors: Barata Ana Margarida Fernandes
Published: August 2021

A demografia portuguesa e europeia da época moderna encontra-se desenvolvida ao ponto de podermos estabelecer padrões e encontrar semelhanças e particularidades em várias regiões. Este artigo tem como objetivo perceber se a paróquia de Serpins se insere nesses padrões, nomeadamente os ritmos de nupcialidade, durante o reinado de D. José I (1750-1777).

A pregação sagrada cristã foi um dos acentos do movimento confessional dos séculos XVII e XVIII na Europa, todavia, a licença para o uso da palavra era resguardada aos homens. Não obstante, algumas religiosas, além de escreverem regulamentos institucionais, cartas e memórias, dedicaram-se à elaboração de textos tanto acerca de sermões quanto em formato sermonístico. Paralelamente, a bibliografia especializada, embora não encontre uma prova cabal da pregação feminina, indica sua possibilidade de existência. Na aridez dos estudos, representações e fontes sobre uma eventual pregação feminina, começamos por identificar as imagens barrocas das religiosas das letras querendo, com isso, materializar as metáforas de uma intelligentsia feminina, representada nos sermões pregados por homens. Depois, garimpamos as relíquias do uso da palavra pelas vozes femininas portuguesas, procurando demonstrar sua literacia no universo parenético, assim como a convicção de que essa lacuna não implica numa inexistência, mas antes num silenciamento.

Retour des expériences individuelles de stage pour un apprentissage collaboratif
Authors: Grandjean Jacques
Published: August 2021

S’appuyant sur des théories du groupe et des apports théorico-pratiques sur la méthode de conduite de groupe, l’auteur montre en quoi l’expérience du groupe et du travail de groupe, régulée par un conducteur de groupe expérimenté, contribue à l’apprentissage de la complexité et de co-apprentissage permettant l’acquisition de compétences psychosociales et d’aptitudes au travail collaboratif.

Il s’appuie sur l’analyse d’un séminaire de retour d’expérience du stage d’ingénieur pour montrer qu’en mettant le groupe, lieu de confrontation des différences, au centre du dispositif, il est possible de développer les capacités des étudiants au co-apprentissage et d’accompagner l’individualisation de leurs dynamiques professionnelles.
Mesure et évaluation de la qualité des pratiques de développement des compétences informationnelles au sein du réseau de l'Université du Québec
Authors: Bélanger Guy , Lemieux Marie-Michèle , Boisvert Denis
Published: August 2021

Une multitude de pratiques diversifiées ont été mises en œuvre afin de favoriser le développement des compétences informationnelles (CI) chez les étudiants du réseau de l’Université du Québec. Ces pratiques n’ont jamais fait l’objet d’évaluation de leur pertinence, ni des effets engendrés. Afin de contribuer à solutionner cette problématique, une étude méthodologique en trois phases a été conduite au sein de ce réseau. La première phase a permis de valider 339 critères de qualité des pratiques de développement des compétences informationnelles (PDCI) auprès d’experts. La deuxième phase consistait à expérimenter un processus de mesure de la qualité des formations documentaires et de la collaboration interprofessionnelle. Dans la troisième phase, des cercles de qualité constitués dans six universités ont procédé à l’évaluation de leurs résultats. La mise en commun de ces évaluations a permis d’identifier les forces et les points faibles significatifs en matière de PDCI. Les forces identifiées sont la qualité de la prestation et le niveau d’expertise démontrés par les bibliothécaires ainsi que leur relation avec les professeurs. Les points faibles se réfèrent à la faible collaboration interprofession­nelle et aux stratégies pédagogiques employées dans le cadre des formations documentaires. Une observation pour le moins paradoxale se dégage des résultats. Alors que la relation entre les bibliothécaires et les professeurs constitue la troisième force en importance, la collaboration interprofessionnelle a été identifiée comme le principal point faible. Ce constat a conduit les auteurs à définir un continuum de pratiques collaboratives permettant de préciser les différents niveaux de travail collaboratif.

ABSTRACTHealth is one of the concurrent affairs that must be fulfilled by the government. Based on the Peraturan Menteri Kesehatan No. 43 of 2016, minimum service standards (SPM) are provisions regarding the type and quality of basic services which are mandatory government affairs that are entitled to be obtained by every citizen minimally. SPM has 12 indicators where all these indicators should ideally reach the target of 100% as a minimum, but not all indicators can achieve 100% results. This can be caused by non-financial resource factors that have not been fulfilled. The aim of this study is to compare the factors of non-financial resources at the Puskesmas Salaman 1 and Puskesmas Gamping 1 in the implementation of the SPM in the health sector. The study was conducted with qualitative methods with a case study approach. The result show that the factors of non-financial resources in the Puskesmas Gamping 1 and Puskesmas Salaman 1 have been adequately fulfilled, but there are some obstacles experienced, namely excessive workload so that one person holds several programs, the quality of human resources is different, not all drug stocks and reagents provided so that it must procure itself, and so forth. This obstacle indirectly affected the achievement of minimum health service standart in Gamping 1 Puskesmas and Salaman 1 Puskesmas so that they could not reach the target.

Authors: Trisnaningtyas Wenny , Retnaningsih Retnaningsih , Rochana Nana
Published: August 2021

Background: Many studies on pressure injury prevention bundles have been conducted outside the Intensive Care Unit (ICU). The bundles, which include multi interventions, have proven effective in reducing pressure ulcer incidents compared to a single intervention. However, the existing review studies on pressure injury prevention in ICUs still only investigate a single intervention rather than multi interventions. Only few reviews, to our knowledge, involves prevention bundle strategies in the ICU.Purpose: This study aims to review the effects of the pressure injury prevention bundles of care on the incidents of pressure injury in critically ill patients and the intervention measures of the care bundles.Methods: This review searched published articles from several databases, namely EBSCO, ScienceDirect, PubMed, ProQuest, Google Scholar, and Scopus from 2009 up to 2020. PRISMA flowchart was used to select relevant articles using several inclusion and exclusion criteria, resulting in 17 article from 50 eligible full-text articles for assessment. The included studies were assessed for their quality using Joanna Briggs Institute (JBI) critical appraisal tools. The synthesis was then conducted narratively.Results: As many as 17 studies, which mostly had good quality yet evidence level of II, were included in the analysis. The findings showed that the pressure injury prevention bundles of care decreased pressure injury incidents as many as 4.3%-36.2% in developed countries and 4.16%-21% in developing countries. Moreover, the bundles of care which significantly reduced the incidents of pressure injury consisted of 7 intervention measures, which were pressure injury risk assessment using Cubbin Jackson scale, skin assessment and care, repositioning, nutrition, education, support surface, and medical device care.Conclusion:The review concluded that the pressure injury prevention bundles of care in critically ill patients significantly reduced the incidents of pressure injury. The study recommends more studies with stronger evidence levels to carry out and utilize 7 intervention measures as a preventive standard of care in critically ill patients.

Published: August 2021

Background: The diabetes mellitus cases have significantly increased in Indonesia over recent years. Health education for patients has often been carried out; however, education using self-instructional methods, which provided self-learning to solve problems by adjusting the patient's ability to improve self-care behaviors, has not been widely used.Purpose: This study aimed to analyze the self-care behaviors of diabetic patients with the application of self-instructional training.Methods: This research was a quasi-experimental study with a non-equivalent pretest-posttest with a control group design. The participants were 73 diabetic patients in the out-patient units selected by a purposive sampling technique, and divided into two groups: the intervention group (n=37) and the control group (n=36). The intervention group received a self-instructional training program which was carried out in two sessions using a booklet; each session lasted for 45 minutes. The Summary of Diabetes Self-Care Activities (SDSCA) questionnaire was used to collect diabetic patients' self-care behavior data. Wilcoxon and Mann-Whitney tests were employed for data analysis.Results: Self-care behaviors of patients with diabetes mellitus increased before and after the training in both groups (p=0.000). However, the increase in the intervention group was higher than that in the control group, from 46.46±5.014 to 58.03±7.320 and from 47.78±4.929 to 51.64±6.406, respectively. There was also a significant difference in the self-care behaviors of diabetic patients between the intervention group and the control group (p=0.000).Conclusion: Self-instructional training significantly improves self-care behaviors of diabetic patients. Therefore, self-instructional training can be considered to apply in the clinical setting for improving self-care behaviors of diabetic patients to prevent complications, and for enhancing nursing care of diabetes mellitus.
Poincaré Inequality for a Mesh-Dependent 2-Norm on Piecewise Linear Surfaces with Boundary
Authors: Walker Shawn W.
Published: August 2021

We establish several useful estimates for a non-conforming 2-norm posed on piecewise linear surface triangulations with boundary, with the main result being a Poincaré inequality. We also obtain equivalence of the non-conforming 2-norm posed on the true surface with the norm posed on a piecewise linear approximation. Moreover, we allow for free boundary conditions. The true surface is assumed to beC2,1C^{2,1}when free conditions are present; otherwise,C2C^{2}is sufficient. The framework uses tools from differential geometry and the closest point map (see [G. Dziuk, Finite elements for the Beltrami operator on arbitrary surfaces,Partial Differential Equations and Calculus of Variations, Lecture Notes in Math. 1357, Springer, Berlin (1988), 142–155]) for approximating the full surface Hessian operator. We also present a novel way of applying the closest point map when dealing with surfaces with boundary. Connections with surface finite element methods for fourth-order problems are also noted.
From Dream to Reality: The Ambivalent Role of Nascent Entrepreneurs’ Motivation in the Intention-Action Gap
Authors: Blank Tali Hadasa , Gabay-Mariani Laëtitia
Published: August 2021

This paper addresses nascent entrepreneurs’ intention-action gap by examining the predictive and the moderating role of different types of motivations. We draw on the theory of planned behavior and on action theory to explain the entrepreneurial action of 205 student nascent entrepreneurs operating in academic incubators within the French higher education system. Our results demonstrate an indirect influence of extrinsic and intrinsic motivation on entrepreneurial action. When referring to motivation as moderating the relationship between intention and action, we show that mid-levels of extrinsic and intrinsic motivation reinforce the positive association between nascent entrepreneurs’ intentions and actions. Our study demonstrates the importance of distinguishing between motivational and volitional phases of the entrepreneurial process, and provides new insights for academic institutions seeking to incubate businesses created by student nascent entrepreneurs.

Published: August 2021

Liquid–gas ejector as a key component of jet loop reactor (JLR), plays an important role in the continuous production of gas–liquid mixing reaction. In this paper, a formula for estimating the gas induction of the ejector is presented. The effects of nozzle radius and mixing length on gas induction of liquid–gas ejector for gas–liquid mixing are simulated, and the formula is verified. Focusing on the efficiency and gas induction, the geometrical parameters are analyzed for the same cases, so that the performance of the ejector can be thoroughly understood. The results show that the optimum mixing section length to diameter ratio (LDR) is about 5–7, and the decrease of nozzle outlet radius can increase the gas induction, which provides a reference for the evaluation of gas induction for liquid–gas ejector and has crucial guiding significance for the design of nozzle and mixing section of liquid–gas ejector in industry.
On the fast approximation of point clouds using Chebyshev polynomials
Authors: Weisbrich Sven , Malissiovas Georgios , Neitzel Frank
Published: August 2021

Suppose a large and dense point cloud of an object with complex geometry is available that can be approximated by a smooth univariate function. In general, for such point clouds the “best” approximation using the method of least squares is usually hard or sometimes even impossible to compute. In most cases, however, a “near-best” approximation is just as good as the “best”, but usually much easier and faster to calculate. Therefore, a fast approach for the approximation of point clouds using Chebyshev polynomials is described, which is based on an interpolation in the Chebyshev points of the second kind. This allows to calculate the unknown coefficients of the polynomial by means of the Fast Fourier transform (FFT), which can be extremely efficient, especially for high-order polynomials. Thus, the focus of the presented approach is not on sparse point clouds or point clouds which can be approximated by functions with few parameters, but rather on large dense point clouds for whose approximation perhaps even millions of unknown coefficients have to be determined.
