Agency costs and the monetary transmission mechanism
Authors: Reiter Michael , Sveen Tommy , Weinke Lutz
Published: February 2019

Once New Keynesian (NK) theory is combined with a standard model of lumpy investment, the resulting framework loses its ability to generate a realistic monetary transmission mechanism. This is the puzzle uncovered in Reiter, Sveen, and Weinke [Reiter, M., T. Sveen, and L. Weinke. 2013. “Lumpy Investment and the Monetary Transmission Mechanism.” Journal of Monetary Economics 60: 821–834.]. The simple economic reason behind it is the unrealistically large interest rate elasticity of investment, as implied by the standard theory of lumpy investment. In order to address this puzzle we develop a NK model featuring fully flexible investment combined with a financial friction. This model is used to isolate the quantitative importance of the financial friction for the monetary transmission mechanism.
Flipping the class – University chemistry students’ experiences from a new teaching and learning approach
Authors: Broman Karolina , Johnels Dan
Published: February 2019

University chemistry courses have for a long time had a similar conventional approach to teaching, with chemistry professors lecturing in a traditional manner. Today, flipped learning approaches have found their ways into higher education with positive results. In particular, US innovations in this area have made positive impressions on Swedish university chemistry educators, resulting in an interest and curiosity in integrating a flipped model into the course curricula. The rationale behind flipped learning is to incorporate an active learning approach into lecture, thereby increasing both student engagement and learning outcomes. In this paper, an implementation project where an organic chemistry course has changed focus from traditional teaching to flipped learning, will be presented. The focus in this mixed-methods study will be on students’ cognitive and affective responses when meeting a new teaching and learning approach. Through following a project where a conventional approach to an organic chemistry course is changed into a more student-active focus, we elaborate on implications for course development of chemistry curricula.

Published: February 2019

The possible role of environmental change, especially sea level change, as a stimulus for the development of human residence and migration is poorly understood. We investigate this problem by showing a record of sea-level change and coastal transformation based on a sediment core (FN1 core) and a Neolithic site (Pingfengshan site) obtained from the Funing bay on the northeast coast of Fujian, China. The Funing bay coastal area represents a unique feature in China’s Neolithic cultures, comprising a silty beach dominated by quartz-rich sand and several important sites of Huangguashan cultural period.

Samples from FN1 core and Pingfengshan site were taken for grain size ananlyses and for optically stimulated luminescence (OSL) dating. The blue-light stimulated OSL signals were measured by the single aliquot regenerative dose (SAR) protocol to determine the ages of of the samples. Samples from FN1 core yield OSL ages ranging from 49.9 ka to 0.8 ka, providing the systematic geochronological evidence for the sea level change of Funing bay. The comparison of sea level change and Neolithic cultural periods presents a good relationship in coastal area of Fujian, China since about 7 ka before present. In detail, the cultural types of Keqiutou culture and Huangguashan culture all belong to coastal mountainous culture, of which flourishing periods corresponds to the higher sea level periods of mid-late Holocene. Tanshishan culture belongs to estuarine coastal culture, and most sites of this period correspond to a lower sea level located at lower altitudes.
Modeling Phase Behavior of Semi-Clathrate Hydrates of CO2, CH4, and N2 in Aqueous Solution of Tetra-n-butyl Ammonium Fluoride
Authors: Mesbah Mohammad , Abouali Galledari Sanaz , Soroush Ebrahim , Momeni Masumeh
Published: February 2019

Semi-clathrate hydrates are members of the class of clathrate compounds. In comparison with clathrate hydrates, where the networks are formed only by H2O molecules, the networks of semi-clathrate hydrates are formed by mixtures of H2O and quaternary ammonium salts (QASs). The addition of QASs to the solution enables to improve the formation of semi-clathrate hydrates at much milder conditions comparing to clathrate hydrates. In this work, we study the phase equilibria of semi-clathrate hydrates of CH4, CO2, and N2 gas in an aqueous solution of tetra-n-butyl ammonium fluoride (TBAF). An extension of the Chen–Guo model is proposed as a thermodynamic model. The Peng–Robinson equation of state (PREOS) was applied to calculate the fugacity of the gas phase and in order to determine the water activity in the presence of TBAF, a correlation between the system temperature, the TBAF mass fraction, and the nature of the guest molecules has been used. These equations were solved simultaneously and through optimizing tuning parameters via the Nelder–Mead simplex algorithm. The results are compared to experimental data and good agreement is observed.

Authors: Singh Arunendra , Tiwari Amod Kumar , Bhattacharya Pronaya
Published: February 2019

Data centers are very critical elements which store and distribute data over the Internet. current data centers heavily rely on electronics, and thus require vast amount of power and speed is limited. These limitations can be tackled using optical technology. In general optical devices consume lesser amount of power, and support very high data rates. In this paper, a hybrid buffer-based optical packet switch which can be used in data centers as aggregated or core switches is discussed. The physical layer analysis is presented and performance is measured in terms of bit error rate (BER) obtained at various power levels. The analysis is carried out in presence of crosstalk of various components and for acceptable BER≤10–9, minimum power required for all optical, all electronic and hybrid buffer is evaluated. Finally power penalty is also evaluated which is required to overcome the effect of amplified spontaneous noise (ASE) and components crosstalk.

Published: February 2019

Sigma Delta Radio over Fiber (S-DRoF) systems are looked upon as an enabling technology due to their advantages that comes due to combination of analog and digital radio over fiber (RoF) systems. In this paper, we have proposed and experimentally demonstrated a Multi-stAge-noise-SHaping (MASH) based Sigma Delta Modulated RoF system targeting 5G C-RAN (cloud/centralized radio access network) fronthaul applications. The evaluation has been done for LTE 20 MHz signal having 256 quadrature amplitude modulation with a carrier frequency of 3.5 GHz up to 5 Km of Standard Single Mode Fiber (SSMF). Furthermore, a comprehensive analysis of the design is explained followed by the experimental setup. The performance is reported in terms of error vector magnitude (EVM) and adjacent channel leakage ratio. It is concluded that S-DRoF substantiates the desired range of the 5G C-RAN fronthaul networks.
On the Borderline: Who Is a “Traditional Inhabitant” under the Torres Strait Treaty?
Authors: Corrin Jennifer
Published: February 2019

The Torres Strait Treaty between Australia and Papua New Guinea (“PNG”) came into force in 1985. This unique treaty, which defines the maritime, seabed and fisheries boundaries between Australia and PNG, is recognised as one of the most complex, but imaginative maritime delimitation solutions in existence. The Treaty creates a Protected Zone with a view to safeguarding the traditional way of life and livelihood of traditional inhabitants of the Torres Strait and adjacent coast of PNG. Traditional inhabitants are allowed relatively unrestricted cross-border movement into the Protected Zone for the purpose of performing traditional activities. “Traditional inhabitants” are defined by the treaty, but the relevant provision is ambiguous and the question of who is within the terms of the Treaty is highly contentious. The problem is exacerbated by the competing layers of law which govern the Strait and surrounding Borderlands, and by the dissonance between State law, customary laws, and the practical application of the Treaty. This paper looks at the meaning of “traditional inhabitants” and some of the other issues surrounding this question.
Der Genitiv in der „Leichten Sprache“ – das Für und Wider aus theoretischer und empirischer Sicht
Authors: Lange Daisy
Published: February 2019

Rulebooks of Easy-to-read (ETR) German recommend to strictly avoid the genitive and to replace it by “von”-phrases with dative. This is backed by the assumption that for the target groups of ETR German genitive-phrases are generally harder to understand than “von”-phrases. However, there has been no empirical foundation for this assumption. The test reported in this paper addressed this problem and wanted to find out whether genitive is really harder to understand than “von”-phrases for two target groups: 17 adults with intellectual disability and 16 functional illiterates, that is people, who learned to read but, due to multiple reasons, do not have reading skills (anymore) that are sufficient for everyday life. The test was designed as multiple-choice test and compares the intelligibility of common forms of the attributive genitive (i.a. genitivus obiectivus, genitivus partitivus) with their “von”-paraphrases. The participants had to read and understand sentences and subsequently choose between statements that applied to the sentences or not. The overall results show that the tested forms of the attributive genitive were easy to understand. Comparing genitive-phrases and “von”-phrases there were no significant differences. That means, both forms were easy to understand for the participants. Some genitive forms were even easier to understand than the “von”-paraphrases. The results lead to the conclusion that the general prohibition of genitive in ETR German has to be revised.
„Mit Rechten sprechen“ – Versuch einer Annäherung aus politolinguistischer Sicht
Authors: Niehr Thomas
Published: February 2019

This article presents polito-linguistics as a sub-discipline of applied linguistics. Its development from a rather morally and politically motivated, prescriptive linguistic critique to a methodologically-committed linguistics could make it seem predestined not only to analyse the use of right-wing language, but also to conduct a conversation with right-wing people. Furthermore, it is argued that such a conversation should not be overburdened with the hope that it could convince supporters of right-wing or even right-wing extremist ideologies of the dangers of their thinking and acting and thereby win them over to basic democratic convictions. Rather, it can at best be a matter of using “trialogical communication” to draw the attention of possible sympathisers and followers to the dangerous consequences of numerous right-wing and right-wing populist demands. By means of examples it is shown that these demands are made based on a limited number of recurring linguistic patterns. A polito-linguistically oriented applied linguistics that draws attention to such patterns and analyses the intentions pursued with these patterns could contribute to a society that feels committed to the model of a civil society founded on democratic values.
Influence of Basalt, Hydrated Lime, and Fly-Ash Fillers on Aging Behavior of Asphalt Mastic Using Essential and Plastic Work of Fracture
Authors: Das Aditya Kumar , Singh Dharamveer
Published: February 2019

The present study was undertaken to investigate the influence of Basalt (B), Hydrated Lime (HL), and Fly-Ash (FA) fillers on aging behavior based on the fracture properties of asphalt mastic. The asphalt mastic samples were prepared in the laboratory using an AC-30 asphalt binder with various combinations of B-HL and B-FA fillers by maintaining a constant filler-binder ratio of 0.8:1 (by mass ratio and 22.5 % by volume). The HL and FA contents were selected as 0 %, 5 %, 10 %, 15 %, and 20 % by the weight of the asphalt binder, and the content of B filler was adjusted accordingly. Correspondingly, three types of asphalt mastic samples, namely, unaged, short-term aged, and long-term aged were prepared in the present study to understand the effects of oxidative aging. Fracture properties of asphalt mastic samples were evaluated at an intermediate temperature using a Double Edge Notched Tension test. The analysis of fracture behavior includes the load-displacement curve pattern, Total Work of Fracture (TWF), Essential Work of Fracture (EWF), Plastic Work of Fracture (PWF), and Critical Tip Opening Displacement (CTOD) values. The results showed that nature, surface texture, mineralogy, and interaction ability of HL and FA fillers strongly influence the aging and fracture resistance of the asphalt mastic. The load-displacement curve pattern, TWF, and PWF values signify a clear indication of an increase in ductile behavior with the incorporation of HL or FA fillers. Similarly, the EWF and CTOD values showed that the inclusion of HL or FA fillers in the asphalt mastic enhanced the aging and fracture resistance behavior. The inclusion of the HL filler has a predominant impact in comparison to the FA filler in the enhancement of both the aging and fracture resistance of asphalt mastic.
Low Temperature Study on the Behavior of Reinforced Bitumen in Asphalt via Addition of Synthesized Basalt
Authors: Honarmand Mehrdad , Tanzadeh Javad , Jandaghi Hamid Reza
Published: February 2019

In traffic engineering, one of the problems presented by slate pavement, besides being costly to repair and maintain, is the insufficient resistance of bitumen against traffic loads in low temperatures. In this study, the effect of synthesized basalt modifier has been assessed via four different tests to improve bitumen performance. Hence, the enhancement of resistance to traffic loads at low temperatures as an essential problem of asphalt superstructure in traffic engineering has been taken into account. The bending beam rheometer test was conducted at three temperatures of −6°C, −12°C, and −18°C, and the softening point and permeability index tests were performed. A Fourier transform infrared spectroscopy test was carried out to identify the structure of the modifier additives. The prepared samples of synthetic basalt-reinforced foam bitumen and synthetic basalt bitumen were examined, each having three values of 2, 4, and 6 % of reinforcement agent. The results showed that the bitumen mixture including 6 % synthetic basalt has the lowest operating temperature compared with the base counterpart having the same resistance to traffic loads at low temperatures. In addition, the temperature sensitivity of synthetic basalt-reinforced foam bitumen depressed by diminishing the modifier amount because adding the 6 % synthetic basalt to the base bitumen increased it from −0.65 to 0.91. The obtained results indicated that the achieved modified bitumen with optimal temperature sensitivity could be a good choice for employment in road construction.

Published: February 2019

This study investigates the effect of adding a small concentration (0–0.5 wt. % addition by mass of cement) of graphite nanoplatelets (GNP) to cementitious materials. GNP-water-surfactant suspensions with various surfactant concentrations (0–20 mg/mL) and sonication times (0.5–6 h) are prepared and subjected to different protocols (long-term standing and centrifugation). Then, dispersion and stability are qualitatively observed through digital imaging and scanning electron microscopy after long-term standing and quantitatively evaluated by calculating the absorbance spectra ratio. Furthermore, the mechanical properties of GNP-reinforced cement (GNPRC) are investigated. The results show that 8 mg/mL and 4.5 h are the best choices for the surfactant concentration and sonication time, respectively. Also, obvious reinforcement for the mechanical properties of GNPRC is found; specifically, the 0.05 wt. % addition of GNP increases the compressive strength by 7.5 % and 16.7 % after 7 days and 28 days curing, respectively. Then, between the GNP dosages of 0 and 0.5 wt. %, the flexural strengths at 7 days and 28 days continuously increase, up to 55.6 % and 53.3 %, respectively.
Heritage Failure and Its Public
Authors: Rico Trinidad
Published: February 2019

The work and historiography of heritage studies and preservation rely significantly on a growth model. They present disciplinary engagements with their subject of study as a slow progression towards a more effective and sustainable involvement of diverse voices, values, and methodological approaches. In this paper, however, I address the role of failure in this field using the particular example of a heritage civil society in Doha, Qatar. How does the field of heritage studies address negative results and what does this reveal about the scope and aims of an expanding discipline?
A Heritage of Resilience
Authors: Lonetree Amy
Published: February 2019

This article explores the importance of a unique and rich collection of photographs of Ho-Chunk people taken between 1879 and 1942 by Black River Falls, Wisconsin, photographer Charles Van Schaick. Unlike the collections of Edward Curtis who sought to capture images of a “vanishing race” for ethnographic or commercial purposes, these were photographs that Ho-Chunk families themselves commissioned for their own personal use, and for the most part, controlled how these images were circulated. Today these images are powerful representations of Ho-Chunk tribal and family history, and reflect a heritage of resilience. The stories the images convey of the importance of family, place, ongoing colonialism, and survivance are the central themes of the Ho-Chunk experience in the late nineteenth and early twentieth centuries. Attention to how we begin to theorize the diversity of Indigenous peoples’ affective responses to these historic images will also be explored through an analysis of my own engagement with family images in the visual archive.
A Heritage of Reciprocity
Authors: Daehnke Jon D.
Published: February 2019

Canoes, and the protocols attached to them, play a central role in cultural revitalization and resilience for many Indigenous nations of the Pacific Northwest. The revitalization of canoe culture is most visibly present in Tribal Journeys, a weeks-long paddle and gathering of Indigenous nations that annually brings together thousands of Native American/First Nations citizens. The Chinook Indian Nation has been an active and early participant in canoe resurgence in general, and Tribal Journeys specifically. For the Chinook, canoe protocols reflect a vision of “reciprocal heritage” that is located in embodied practice, is based in tribal cultural values of reciprocity and place, and is forward-looking. Perhaps most importantly, canoe culture and the performance of protocols occur explicitly outside of the framework of the colonial nation-state. In this sense the performance of protocol is not just an aspect of culture, it is fundamentally an act of decolonization.

Drawing on Anishinabe concepts of holistic health and well-being, this article explores ways that repatriation of ancestral remains and cultural items can contribute to healing and well-being in Indigenous communities. The focus is on “Indigenous storywork” and embodied practices amongst those who are engaged in reclaiming ancestral remains and cultural items, with examples from the author’s experience in repatriation, reburial, and reclaiming cultural heritage. The author describes her work developing a graphic narrative about repatriation as a method of storywork. She describes her use of comics and other storywork practices in teaching, and as a means of bringing Indigenous teaching and learning practices into higher education.
Ausgeschlossene einführen in die Liebe des Vaters. Ein Anliegen des Apostels Paulus im Römerbrief
Authors: De Rycke Filip
Published: February 2019

In Zusammenhang mit der Behauptung, dass Juden und Heiden gemeinsam am Bunde Gottes teilhaftig sind, wird der Römerbrief von Paulus von einem heilsgeschichtlichen Zug gekennzeichnet. In der Dynamik der Einführung der bisher ausgeschlossenen Heiden in die Liebe Gottes in Christus haben die Motive der Herrlichkeit und des Verherrlichen eine zentrale Bedeutung. Paulus unterscheidet dabei drei verschiedene Schritte: erstens der gemeinsame Grund des Naturgesetzes, zweitens die vorherige Wirkung der Barmherzigkeit Gottes und drittens die gegenseitige Annahme aller Gläubigen in die Kirche.
Die Überwindung der gesellschaftlichen Exklusion als Verpflichtung für die Soziallehre der Kirche
Authors: Wiemeyer Joachim
Published: February 2019

Aufgrund der Erfahrungen in seinem Heimatkontinent Lateinamerika, in dem viele Menschen am Rande der Gesellschaft leben, tritt Papst Franziskus entschieden für die „Ausgeschlossenen“ ein. Diese leben häufig an und von Müllkippen, sind als Staatsbürger nicht registriert, ihre Kinder besuchen keine Schulen etc. Der Beitrag macht deutlich, dass die Soziallehre der Kirche alle Menschen umfassend zu Teilhabern ihrer jeweiligen Gesellschaft in allen Kultursachbereichen (Politik, Wirtschaft, Bildung, Gesundheit) machen will. Vor dem Hintergrund sozialwissenschaftlicher Theorien (Luhmann, Olson) wird er exemplarisch erläutert, dass in westlichen Industriegesellschaften als Großgruppen vor allem Langzeitarbeitslose und Migranten von der vollen Teilhabe an der Gesellschaft ausgeschlossen sind und sich daher die Integrationsanstrengungen vor allem auf diese beiden Personenkreise beziehen muss.
Problem wykluczenia społecznego w kościelnej posłudze słowa
Authors: Sławiński Henryk
Published: February 2019

Problemem społecznym, na który szczególnie zwraca uwagę papież Franciszek, jest wykluczenie społeczne. Nie chodzi w tym nowym zjawisku o wykorzystywanie ludzi, ale o całkowite odrzucenie; powiedzenie komuś, że jest do niczego niepotrzebny. Takie traktowanie człowieka jest całkowicie sprzeczne z Dobrą Nowiną Jezusa Chrystusa, który wyklucza „wykluczenie świadome” kogokolwiek. Artykuł podejmuje tę kwestię, a także omawia „wykluczenie nieświadome”, które wynika z zastosowania języka, który nie jest wystarczająco inkluzywny. Zadaniem głosicieli słowa Bożego jest podejmować problem wykluczenia i ukazywać, że Jezus utożsamił się z wykluczonymi. Ewangelia dostarcza przykładu przeobrażenia społecznego wskutek interwencji Jezusa. Historia niewidomego żebraka Bartymeusza z Jerycha jest paradygmatem dla przepowiadania na rzecz integracji wykluczonych.
Włączanie wiernych w sytuacjach nieregularnych w życie wspólnoty Kościoła
Authors: Rojowski Leszek
Published: February 2019

Adhortacja Amoris laetitia daje zdecydowany impuls do działań na rzecz pełniejszego włączenia w życie Kościoła wiernych, którzy znajdują się w sytuacjach nieregularnych. Ma się to dokonać dzięki procesowi towarzyszenia i rozeznania, który po uwzględnieniu złożoności i różnorodności sytuacji, okoliczności łagodzących, i innych czynników wskaże konkretne możliwości ich szerszej integracji. Powinna się ona wyrażać w podejmowaniu różnych posług i form aktywności w dziedzinie liturgicznej, duszpasterskiej, edukacyjnej, instytucjonalnej i dobroczynnej. Przykładem wdrażania nauczania Franciszka w tej materii jest dokument Pastoral guidelines for implementing Amoris laetitia wypracowany przez archidiecezję w Filadelfii. Łączy on w swoich rozwiązaniach wskazania zawarte w Amoris laetitia z wcześniejszym nauczaniem Kościoła, zwłaszcza tym wyrażonym w Familiaris consortio. Normy tego dokumentu z jednej strony promują włączanie wiernych w sytuacjach nieregularnych w życie Kościoła, a z drugiej określają zadania, które nie mogą przez nich być podjęte. Jest to uzasadnione koniecznością kierowania się nie tylko miłością i miłosierdziem, ale też prawdą o nierozerwalności małżeństwa.
Kościół wobec zagrożeń związanych z wykluczeniem przez starość
Authors: Dziedzic Jan
Published: February 2019

Współczesna dyskusja na temat starości koncentruje się wokół pogłębiającego się niżu demograficznego. Ta nowa rzeczywistość staje się wielkim wyzwaniem dla państwa, społeczeństwa, rodziny i Kościoła. Aby zapobiec odsuwaniu osób trzeciego i czwartego wieku na margines, należy respektować osobową godność w starości. Kościół akcentuje w swoim nauczaniu absolutną wartość osoby ludzkiej, i to w każdej bez wyjątku fazie jej istnienia.Kształtowanie dojrzałych postaw wobec starości jest kluczowym działaniem potrzebnym do eliminowania zachowań prowadzących do marginalizacji i dyskryminacji osób w podeszłym wieku. Każde społeczeństwo jest zobowiązane do szacunku wobec osób starszych. Nieodzowna jest też solidarność między różnymi pokoleniami.Człowieka starego nie należy traktować wyłącznie jako tego, który potrzebuje pomocy. Jedną z dróg do rozwiązania problemów dotyczących starzenia się ludzkości jest włączenie człowieka starszego w aktywne życie społeczne. Seniorzy nie powinni dobrowolnie wycofywać się z życia społecznego. Ich zadaniem jest wspomaganie środowisk pracy, udzielanie młodym rad, dawanie świadectwa o wartościach humanistycznych, wprowadzanie równowagi w życie społeczne.
Przeciwdziałanie marginalizacji niepełnosprawnych w życiu wspólnotowym Kościoła

Published: February 2019

Od początku swego istnienia Kościół podejmował opiekę nad ludźmi niepełnosprawnymi. Jednym z jej elementów jest troska o to, by angażowali się podmiotowo w życie jego własnej wspólnoty. W artykule zostały ukazane dążenia współczesnego Kościoła do aktywnego angażowania osób niepełnosprawnych. W pierwszej części zostały przestawione wysiłki zmierzające do ich zaangażowania w rodzinnych parafiach. Druga część zawiera obraz duszpasterstwa nadzwyczajnego i troski o włączanie niepełnosprawnych w życie Kościoła na szczeblu diecezjalnym i ponaddiecezjalnym. Trzecia część ukazuje wspólnoty życia z niepełnosprawnymi, funkcjonujące na podobieństwo Kościoła domowego. W zakończeniu wskazano na możliwości dalszej pracy z niepełnosprawnymi, zmierzającej do ich aktywizacji we wspólnocie Kościoła.
Islam und Christentum. Exemplarische Einblicke in Exklusion und Inklusion im Religionsunterricht
Authors: Grümme Bernhard
Published: February 2019

Der Dialog zwischen Christentum und Islam ist schwierig. Er kann nur erfolgreich sein, wenn er nötige Differenzierungen und zugleich die wirtschaftlichen, historischen und kulturellen Verwurzelungen berücksichtigt. Theologisch ist dafür aber auch ein angemessenes Wahrheitsverständnis erforderlich. Erst vor diesem Hintergrund ist dann ein Interreligiöses Lernen möglich. Um die eigenen Ziele der Begegnung, der Anerkennung und des Dialogs zu erreichen, sind hierfür freilich die Mechanismen des Lernens selber selbstkritisch zu analysieren. Sonst wird ein solches Interreligiöses Lernen als verkennende Anerkennung verfehlt.
The Four Problems which Old Testament Married Couples Grapple with
Authors: Majewski Marcin
Published: February 2019

In the context of a lively debate on the encyclic of Pope Francis Amoris laetitia, in this article I take up the four most important problems that marriages in the Old Testament grappled with: polygamy, or marrying multiple spouses, lack of offspring, infidelity, or betrayal, and divorce. It is only against this issues that the profound novum of Catholic teaching on marriage emerges. The proposal will be that problems afflicting couples of biblical time are not so different from the ones besetting contemporary couples.

Published: February 2019

Celem tego artykułu było zbadanie, jak św. Aniela była posłuszna Duchowi Świętemu w swoim życiu? Analizy świadectw jej życia oraz jej pism pokazały, że była prowadzona przez Ducha Świętego od wczesnego dzieciństwa i młodości. Podczas trudnych doświadczeń, jak śmierć rodziców i siostry, była otwarta na miłość do Boga i chciała należeć do Niego. Bóg prowadził ją i uczynił wrażliwą na Jego obecność w niej samej, w innych ludziach, w wydarzeniach. Aniela kochała słowo Boże, była kobietą modlitwy i ascezy. Była otwarta na dary i charyzmaty Ducha Świętego, szczególnie została obdarowana mądrością, proroctwem i oblubieńczą więzią z Chrystusem. Wszystkie te dary były jej dane dla dobra Kościoła, w sposób szczególny dla urszulańskiej wspólny gromadzącej się wokół niej. Święta Aniela stała się proroczym znakiem dla całego Kościoła.

RESUMO Objetivo: analisar a tendência de internações para realização de procedimentos cirúrgicos e de mortalidade cirúrgica no Brasil, no período de 2008 a 2016. Métodos: estudo ecológico, de séries temporais. Os dados sobre internações cirúrgicas e mortalidade entre 2008 e 2016 foram obtidos do Departamento de Informática do Sistema Único de Saúde. A análise de tendência foi realizada por meio de modelos de regressão polinomial. Resultados: foram realizados no período do estudo, 37.565.785 procedimentos cirúrgicos pelo Sistema Único de Saúde, uma média anual de 4.151.050 cirurgias. A média do coeficiente dos procedimentos cirúrgicos foi de 2,12 cirurgias por 100 habitantes/ano, com variação de 1,92 a 2,56 habitantes/ano entre as regiões do país. A taxa de mortalidade cirúrgica foi de 1,63%, com variação de 1,07% a 2,02% entre as regiões. Conclusão: constatou-se tendência significativa crescente dos procedimentos cirúrgicos realizados e de mortalidade cirúrgica; entretanto, o coeficiente de procedimentos cirúrgicos realizados é inferior ao preconizado pela meta internacional, com disparidades regionais no acesso aos cuidados cirúrgicos e na mortalidade, o que compromete a garantia da cobertura universal da saúde preconizada pelo Sistema Único de Saúde.

RESUMO Objetivo: analisar a expressão do Fator de Crescimento do Endotélio Vascular (VEGF), seu receptor (VEGFR-2), idade e tipo histológico de carcinomas avançados de colo uterino com relação à resposta clínica à quimioterapia neoadjuvante. Métodos: foram incluídas 40 pacientes com diagnóstico de carcinoma de colo uterino (IB2 e IVA), com biópsias prévias ao tratamento. Todas as pacientes foram submetidas à quimioterapia neoadjuvante e avaliadas quanto à resposta clínica e à expressão do VEGF. Considerou-se boa resposta clínica uma regressão tumoral total ou maior do que 50%. Resultados: em relação à resposta à quimioterapia, 18 pacientes (45%) apresentaram boa resposta e 22 (55%), má resposta. Quanto à expressão do VEGF, em 16 pacientes foi considerada positiva e em 24, negativa. Quando os casos foram analisados separadamente em relação à resposta à quimioterapia, somente a expressão positiva de VEGF foi associada à boa resposta clínica (p=0,0157). Conclusão: a expressão de VEGF mostrou ser isoladamente, um importante marcador de boa resposta ao tratamento quimioterápico neoadjuvante das pacientes com carcinoma avançado de colo uterino.

Published: February 2019

O objetivo foi verificar se a percepção das desordens físicas e sociais da vizinhança está associada a uma maior pressão arterial sistólica (PAS) e diastólica (PAD), bem como examinar a influência do nível socioeconômico do setor censitário de residência sobre essa associação. Trata-se de um estudo transversal que incluiu uma amostra representativa de 1.720 adultos de 20 a 59 anos, residentes em Florianópolis, Santa Catarina, Brasil. Foram realizadas duas medidas de pressão arterial e coletadas informações referentes à percepção das desordens no bairro de moradia. A variável contextual utilizada foi a média de anos de escolaridade do chefe da família dos setores censitários investigados. A análise estatística incluiu modelos multiníveis, com o primeiro nível representado pelos indivíduos e o segundo, pelos setores censitários. Termos de interação entre os tercis de escolaridade do setor censitário e os tercis de percepção de desordens de vizinhança sobre a pressão arterial foram examinados. Não foram identificadas associações estatisticamente significativas globais entre desordens de bairro e PAS ou PAD. Entretanto, foi identificada uma média de PAS 7,88mmHg (IC95%: 1,38; 14,40) maior entre os respondentes que percebiam mais desordens de vizinhança e residiam em um setor com menor escolaridade, quando comparados com a categoria de referência. As políticas públicas que visam a reduzir ou que tenham impacto sobre os níveis pressóricos sistólico e diastólico na população também devem considerar as características do contexto em que a população está inserida, especificamente aqueles marcados por menores níveis de escolaridade.

Este estudo descreve a tendência dos coeficientes de mortalidade por doenças cerebrovasculares (DCbV) em idosos no Estado de São Paulo, Brasil, entre 1980 e 2012, antes e depois das campanhas de vacinação contra a influenza, e identifica pontos de mudanças. Trata-se de um estudo ecológico de série temporal, realizado com dados de óbitos do Sistema de Informações sobre Mortalidade do Ministério da Saúde e dados populacionais do Instituto Brasileiro de Geografia e Estatística. Para análise dos dados, foram utilizados modelos de regressão linear, polinomial e joinpoint regression. Entre 1980 e 2012, foram registrados 480.955 óbitos por DCbV. Os coeficientes médios de mortalidade diminuíram em ambos os sexos para todas as faixas etárias analisadas, com maior redução nas idades mais longevas e no sexo masculino. Observou-se queda significativa na tendência de mortalidade em 1998 para o sexo masculino, na faixa de 60-69 anos (annual percent change - APC = -3%, IC95%: -4,3; -1,6) e para o total dos idosos (APC = -3,8%, IC95%: -4,4; -3,1). Considerando-se o período como um todo, não se observaram pontos de mudanças para a faixa de 70-79 (average annual percent change - AAPC = -3,3%, IC95%: -3,5; -3,1) e, no sexo masculino, para o grupo ≥ 80 anos (AAPC = -2,9%, IC95%: -3,1; -2,6). Para o total de idosos, a redução percentual média foi de 3,1% ao ano (AAPC = -3,1%, IC95%: -3,5; -2,7). Os resultados mostraram redução da mortalidade por DCbV no período estudado, com diferentes variações percentuais de queda dos coeficientes. Os achados deste estudo adicionam informações para o debate sobre o possível efeito das campanhas de vacinação na redução da mortalidade por DCbV na população idosa.

ABSTRACT: Hyptis marrubioides (Lamiaceae) is a medicinal plant that is native from Brazilian Cerrado. In vitro propagation techniques make use of elicitors to alter metabolic pathways, affecting how molecules are produced both qualitatively and quantitatively. This research aimed to evaluate how abiotic elicitors salicylic acid (SA) and silver nitrate (SN) at concentrations of 30µM or 60µM influence Hyptis marrubioides seedling growth by two different in vitro culture methods. The rutin content was quantified by HPLC-DAD. Compared to an untreated culture, the H. marrubioides methanolic extracts cultured in MS medium for 10 days followed by culture in MS medium containing SN (30µM) for 20 days had 1.28 times higher rutin content. In a second experiment, seedlings were cultured in MS medium for 20 days, and then the desired elicitor was added to the culture and allowed to remain in contact with the medium for three and six days. SA (30µM) gave the best results: rutin production was 16.56-foldhigher than the control after six days. SN (30µM) increased the rutin content by 1.17-fold. At the two concentrations evaluated during the elicitation experiments, neither SA nor SN altered the growth parameters shoot length, leaf number, and fresh and dry weight of H. marrubioides seedlings grown in vitro as compared to the control. Based on these results, the abiotic elicitors SA and SN successfully provide Hyptis marrubioides with increased rutin content in vitro.

ABSTRACT: The innate immune system of honeybees mainly consists in antimicrobial peptides, cellular immunity and melanisation. In order to investigate the immune response of honeybees to immune stressors, three stress degrees were tested. Newly emerged bees naturally DWV-infected were collected from a Varroa mite-free apiary and divided into three experimental groups: naturally DWV infected bees, PBS injected bees, and artificially DWV super infected bees. Phenoloxidase activity and haemolymph cellular subtype count were investigated. Phenoloxidase activity was highest (P<0.05) in DWV-superinfected bees, and the haemocyte population differed within the three observed groups. Although, immune responses following DWV infection have still not been completely clarified, this investigation sheds light on the relation between cell immunity and the phenoloxidase activity of DWV-naturally infected honeybees exposed to additional stress such as injury and viral superinfection.

Resumo Ao fundamentar as bases da Mecânica Quântica através da solução de um problema matemático associado a possíveis inconsistĉncias na relação de comutação para os operadores posição e momento linear, von Neumann lança as bases teóricas do que posteriormente resultou na descrição da Mecânica Quântica no espaço de fases. No presente trabalho, complementar à tradução do texto original de von Neumann, analisamos um conjunto específico de resultados, que formam um arcabouço matemático sólido para a concepção de um espaço de fases genuinamente quântico, tornando-o assim um legítimo precursor desta descrição.
Venturino: análise da variação de pressão em um tubo de Venturi utilizando Arduino e sensor de pressão

Published: February 2019

Resumo Geralmente os laboratórios didáticos das escolas de ensino médio e das instituições de ensino que ofertam graduações em Física e áreas correlatas não possuem equipamentos e/ou práticas experimentais sobre hidrodinâmica. Aplicações de relevância tecnológica tais como o tubo de Pitot ou o tubo de Venturi são estudados, geralmente, como simples aplicações matemáticas da Equação de Bernoulli para fluidos ideais. Visando contribuir para a remediação deste problema é proposto nesse artigo a construção de um tubo de Venturi fabricado com materiais de baixo custo e equipado com uma placa microcontroladora Arduino e sensores de pressão modelo BMP280. O aparato proposto nesse artigo permite a visualização de gráficos, gerados em tempo real, da variação da pressão interna em um ponto com o transcorrer do tempo e estabelece relações empíricas entre pressão, velocidade e área do tubo. O aparato já foi utilizado em cursos técnicos integrados do CEFET/Valença e em curso de Física Experimental que compõe a grade curricular da graduação em Engenharia de Alimentos da mesma instituição. Essa prática faz parte de um projeto que visa criar recursos didáticos para desenvolver atividades de ensino baseados no conceito de aprendizagem ativa, utilizando o método Predizer -- Observar -- Explicar (POE).

ABSTRACT The search for new alternatives in order to reuse residues is one way to minimize environmental impacts by promoting sustainable practices. This study analyzed the technical feasibility of briquettes production from urban pruning residue and sugarcane bagasse, turning them into a product with higher added value besides directing their use and reducing their improper disposal. Five treatments were studied from different ratios of the two residues: T1, T2, T3, T4 and T5, respectively made of 100% of urban pruning; 50% urban pruning and 50% sugarcane bagasse; 25% urban pruning and 75% sugarcane bagasse; 10% urban pruning and 90% sugarcane bagasse; 100% sugarcane bagasse. The materials were characterized physically, chemically and energetically. Briquettes were produced and evaluated for mechanical performance, with expansion tests, mechanical resistance and friability to verify the quality of the final product. The treatments 1 and 2 showed the best results, with lower friability and average values of mechanical resistance of 167.14 and 107.56 kgf, respectively. It is concluded that both residues (sugarcane bagasse and urban pruning) had potential for briquette production, as well as the mixture between both materials.

ABSTRACT With the occurrence of prolonged droughts in the Brazilian semi-arid region, water scarcity directly influences agriculture in this region, so that water reuse and bovine manure application become a viable alternative for pepper production. In this context, the present study aimed to evaluate the sustainable production of chili peppers (Capsicum frutescens) under levels of irrigation with treated wastewater and doses of bovine manure. The following bovine manure doses were considered: D1 (0% manure and 100% soil), D2 (10% manure and 90% soil), D3 (20% manure and 80% soil), D4 (30% manure and 70% soil), D5 (40% manure and 60% soil) and D6 (50% manure and 50% soil), based on volume. Three levels of irrigation were applied, based on the water requirement of the crop (WR), namely: 100% WR (L1), 75% WR (L2) and 50% WR (L3). Production variables and physical characteristics of the produced peppers were evaluated. Pepper production (g plant-1) increased as 10% of bovine manure were added in substrate composition. Increasing concentration of bovine manure and using 50% WR provided favorable conditions for the organic production of chili pepper.
Market reaction to bank merger and acquisition events in Brazil: an analysis of the effects of market waves
Authors: Souza João Gabriel de Moraes , Gartner Ivan Ricardo
Published: February 2019

ABSTRACT The aim of this study is to investigate the stock market’s reaction to bank merger and acquisition (M&A) events in Brazil when the market is heated. This article aims to fill the research gap involving bank M&As and their effects, especially those arising from M&A waves. This field remains open in the literature; there is no consensus as to the abnormal returns the investor can expect from this mechanism. The notion that bank M&A markets heat up is discussed and still does not present a consensus in the literature. Therefore, topics that involve research on specific M&A strategies and their effects are interesting for the literature. The results of this research point to the emergence of positive cumulative abnormal returns for rivals of newly-merged acquiring banks and zero ones for acquired banks. This analysis occurs because in heated markets the probability of rival banks becoming involved in M&As increases, leading to market gains and greater market power for acquiring banks and the rapid pricing of acquired bank assets. This result corroborates with the post-merger analysis, in which the accounting performance indicators of the acquiring banks are positive. The market reaction was verified through the use of the event study econometric technique, which was applied in the investigation of the occurrence of abnormal returns in time windows of up to 41 days around the bank M&A events. The study measured the stock market’s reaction to a motivation for M&As, which is the effect of M&A waves. This article contributes to the literature by highlighting specific forms of bank M&As. In particular, the logic of merger by market forces is addressed. This mechanism of mergers by market forces is presented as evidence of the tendency for M&As and not of paid-in earnings.
