Published: March 2019

Abstract. Aerosols can not only participate in fog formation by acting as condensation nuclei of droplets but also modify the meteorological conditions such as air temperature and moisture, planetary boundary layer height (PBLH) and regional circulation during haze event. The impact of aerosols on fog formation, yet to be revealed, can be critical in understanding and predicting of fog-haze event. In this study, we used the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) to investigate a heavy fog event during a multiday intense haze pollution episode in early December 2013 in the Yangtze River Delta (YRD) region in eastern China. Using the WRF-Chem model, we conducted four parallel numerical experiments to evaluate the roles of aerosol-radiation interaction (ARI), aerosol-cloud interaction (ACI), black carbon (BC) and none BC (non-BC) aerosols in the formation and maintenance of the heavy fog event. Only when the aerosols' feedback processes are considered can the model well capture the haze pollution and the fog event. We find that the ARI dominates this fog-haze episode while the effects of ACI are negligible. Our analyses shows that BC plays a more important role in fog formation than non-BC aerosols. The dome effect of BC leads to an increase of air moisture over the sea by reducing PBLH and weakening vertical mixing, thereby confining more water vapor in the near-surface layer. The strengthened daytime onshore flow by a cyclonic wind anomaly, induced by contrast temperature perturbation over land and sea, transports moister air to the YRD region, where the suppressed PBLH and weakened daytime vertical mixing maintain the high moisture level. Then the heave fog forms due to the surface cooling at night in this region. This study highlights the importance of anthropogenic emissions in the formation of advection-radiation fog in the polluted coastal areas.

Published: March 2019

Abstract. A low-cost miniaturized particle counter has been developed by The University of Hertfordshire (UH) for the measurement of aerosol/droplet concentrations and size distributions. The Universal Cloud and Aerosol Sounding System (UCASS)is an Optical Particle Counter (OPC), which uses wide-angle elastic light scattering for the high precision sizing of fluid-borne particulates. The UCASS has up to 16 configurable size bins, capable of sizing particles in the range 0.4–40 micrometer in diameter. Unlike traditional particle counters, the UCASS is an open-geometry system which relies on an external air flow. Therefore the instrument is suited for use as part of a dropsonde, balloon-borne sounding system, as part of an Unmanned Aerial Vehicle (UAV), or on any measurement platform with a known air flow. Data can be logged autonomously using an on-board SD card,or the device can be interfaced with commercially available meteorological sondes to transmit data in real time. The device has been deployed on various research platforms to take measurements of both droplets and dry aerosol particles. Comparative results with co-located instrumentation in both laboratory and field settings are used to assess the performance of the UCASS.
How rainfall event characteristics affect the applicability of I30 as an
index of intense or erosive rainfall: a brief review with proposed new
rainfall index
Authors: Dunkerley David L.
Published: March 2019

Abstract. In many fields, the intensity of rainfall events is expressed using indexes such as I30, the wettest 30-minute interval within a rainfall event. Various limitations attend this usage: I30 cannot be estimated for rainfall events shorter than 30 minutes, including many intense convective storms, and it represents a diminishing proportion of increasingly long rainfall events (representing 10 % of the duration of a 5-hour event but declining to < 2 % of the duration in a 30-hour event). These and other issues connected with I30 and related indices based on fixed clock periods (I15, I60, etc.) can be eliminated if instead, a nominated fraction of the event duration is used as an index, such as the wettest 5 % of the event duration. This index (termed EDf5) can be derived for both short and long rainfall events. Illustrative results are presented for two Australian locations having high-resolution rainfall data and contrasting rainfall climatologies, one arid and one wet tropical. The value of I30 is similar at both sites (7.7 mm h-1 and 7.9 mm h-1) and fails to differentiate between them. In contrast, the average intensity of the wettest 5 % of event durations (EDf5) at the arid site is 7.4 mm h-1, whilst at the wet tropical site, the corresponding value is 3.8 mm h-1. Thus, the EDf5 index indicates a greater concentration of rain at the arid site (i.e., intensity sustained for 5 % of event duration at the wet tropical site is lower). Results exemplify the capacity of the EDf5 index to be applied to short, intense events. The use of a fixed 30-minute clock period to describe intensity at the contrasting field locations has less discriminatory power and may be of less use in the investigation of rainfall characteristics that drive landsurface processes.
A fast monitor and real time early warning system for landslides in the Baige landslide damming event, Tibet, China
Authors: Wu Yongbo , Niu Ruiqing , Lu Zhen
Published: March 2019

Abstract. Landslide Early warning systems has been widely used to avoid potential disaster. In this paper, a fast monitoring and real time precursor predication method is proposed to build the early warning systems for specific landslide. The fast monitoring network in this system uses ad-hoc technology to build rapid site monitoring network consist of Beidou terminals and fracture monitors. The real time precursor predication method based on the KF-FFT-SVM model is conducted to fulfil precursor early warning of in short time. The KF-FFT-SVM model working in this system is established through the analysis of the precursor slide character in deformation data got by the Beidou terminals. The deformation data is considered as the mechanical vibration of specific landslide and the KF-FFT-SVM model is trained to predicate the occurrence of landslide by the real time deformation data. This system not only improves the robustness of site monitoring, but also provides an effective early warning method for specific landslide. It is applied in Baige landslide monitoring and results showed that KF-FFT-SVM early warning model can predication the occurrence of landslide with high accuracy. It will make the early warning work for specific landslide more effective and costless, although numerous continuous monitored precursor slide deformation data are needed to trained the model well.
An adaptive unstructured mesh based solution to topography
least-squares reverse-time imaging
Authors: Liu Qiancheng , Zhang Jianfeng
Published: March 2019

Abstract. Least-squares reverse-time migration (LSRTM) attempts to invert for the broadband-wavenumber reflectivity image by minimizing the residual between observed and predicted seismograms via linearized inversion. However, rugged topography poses a challenge in front of LSRTM. To tackle this issue, we present an unstructured mesh-based solution to topography LSRTM. As to the forward/adjoint modeling operators in LSRTM, we take a so-called unstructured mesh-based “grid method”. Before solving the two-way wave equation with the grid method, we prepare for it a velocity-adaptive unstructured mesh using a Delaunay Triangulation plus Centroidal Voronoi Tessellation (DT-CVT) algorithm. The rugged topography acts as constraint boundaries during mesh generation. Then, by using the adjoint method, we put the observed seismograms to the receivers on the topography for backward propagation to produce the gradient through the cross-correlation imaging condition. We seek the inverted image using the conjugate gradient method during linearized inversion to linearly reduce the data misfit function. Through the 2D SEG Foothill synthetic dataset, we see that our method can handle the LSRTM from rugged topography.
Los efectos en los derechos humanos de las secesiones de Estados y entidades no aceptadas por la comunidad internacional
Authors: López Martín Ana Gemma , Perea Unceta José Antonio
Published: March 2019

El proyecto secesionista de una parte de la sociedad de Cataluña exige reflexionar sobre cómo se han comportado y cómo se comportan actualmente tanto los Estados que se han creado mediante secesión como las entidades de facto, no reconocidas por la comunidad internacional, en lo que respecta a los derechos humanos de las minorías resultantes en ellos. En países como Estonia y Letonia se aprecian situaciones anómalas en relación con la denegación de la nacionalidad a la población de origen ruso por su desconocimiento del idioma nacional, en Eritrea se impidió el regreso de los eritreos que vivían en Etiopía por desconfianza con su movilización a favor del nuevo Estado, en Macedonia se manipularon los distritos electorales para minimizar la representación parlamentaria de los albaneses, etc. Al no haber una norma internacional general que asegure que los nuevos Estados siguen obligados por los tratados en materia de derechos humanos del Estado matriz, el único recurso para asegurar la vigencia de los mismos es la actuación de los organismos internacionales supervisores. En el caso de los Estados, mediante la formulación de una «doctrina de los derechos humanos adquiridos» que impide el vacío legal para el Tribunal Europeo de Derechos Humanos o el Comité de Derechos Humanos de la ONU, y en el caso de las entidades de facto, como Nagorno-Karabaj, Transnistria o la República Turca del Norte de Chipre, con un juego de reglas que impiden ese vacío de responsabilidad en virtud del cual se presume la del Estado titular de la soberanía, presunción que se destruye —sin perjuicio de mantener «obligaciones internacionales positivas»— si una parte del territorio es ocupada militarmente por otro Estado, siendo este el responsable, y sin perjuicio de que, incluso habiéndolo, también pueda exigirse a una autoridad local insurgente si no actúa bajo el control efectivo de esa potencia ocupante. Esta práctica revela una situación jurídica ciertamente peligrosa para la vigencia de los derechos humanos de las minorías resultantes en Estados y entidades secesionadas, situación que debe ser corregida, especialmente en el ámbito regional europeo, para evitar que se repita en eventuales procesos secesionistas, como el que podría acontecer en Cataluña.
The Spectre of Superbugs: Waste, Structural Violence and Antimicrobial Resistance in India
Authors: Doron Assa , Broom Alex
Published: March 2019

At first glance there may seem to be no clear connections between two of humanity’s most pressing problems: environmental waste and antimicrobial resistance (AMR). In fact, as we posit in this paper, there is an inevitable convergence across these medical and environmental domains that hinge on social and economic inequalities. Such intersections have not been given nearly enough emphasis. Here we offer a series of considerations regarding the potential nexus of environmental pollution, waste-work, poverty and the decreasing viability of antimicrobials. We suggest that AMR and environmental pollution will fundamentally shape one another over the course of the coming decades, with differential impacts across socio-economic divides. More perniciously, the coalescing of waste, environmental pollution and reduced potency of pharmaceutical infection management will in turn likely escalate cultural prejudices around hygiene, ‘untouchability’, exclusion and privilege. That is, this nexus of waste and bacterial risk will polarise and divide communities, disproportionately affecting poorer communities. This paper is intended to chart an agenda for the study of this increasingly critical site of bacterial-human-environmental relations. It does so by examining the cycle of infection, risk and vulnerability amongst the most disadvantaged sections of the population in India.
Fairness as a Determinant of the Jigsaw Procedure’s Success in Teaching Undergraduate Psychological Statistics
Authors: Cole-Dixon Angela P. , Glymph-Austin Angela D. , Gill Janel M. , Shivers-Williams Cassandra A. , Roberts Debra D.
Published: March 2019

Undergraduate students (n = 46) completed four lab assignments (two “jigsaw group” assignments and two more traditional individual statistics lab assignments), followed by quizzes and evaluations of their assignments, instructor, and classmates, in a study designed to confirm and extend previous findings of positive effects of the jigsaw procedure in a psychological statistics course. Findings of the study (a) showed expected quiz performance improvement following jigsaw assignments, (b) provided preliminary support for Aronson’s and colleagues’ position that the success of the jigsaw classroom is due in part to decreased perceptions of unfairness, and (c) further established the ecological validity of fair process effects in a setting not previously investigated—the jigsaw classroom. Moreover, our findings suggest that the jigsaw procedure is well-suited for supplementing psychological statistics lectures.
Nurses' drowsy driving prevention strategies: A qualitative exploratory multiple-case study
Authors: Rhodes Gina , Bernstein Joshua , Grendell Ruth
Published: March 2019

Objective: To explore the strategies registered and licensed practical nurses implemented to lessen the possibility of driving while drowsy after working nights in hospitals, nursing homes, and home health facilities. A review of literature indicated shift work, circadian rhythm interruptions and multiple stressors such as age, caring for children/aging parents and working multiple jobs may affect drowsy driving. Studies on global drowsy driving and cultural differences may affect international applicability. Further research was needed to better understand drowsy driving best practices, training modalities for health care workers, and developing a multidisciplinary collaboration between management and night-shift workers.Methods: A qualitative, exploratory multiple-case method was utilized. Registered and licensed practical nurses (N = 12) were interviewed.Results: Identified themes including three major themes emerged from the data analysis. 1) Fatigue is a significant challenge that impedes driving home safely. 2) Night nurses experience significant additional stressors relating to caring for family, school, and multiple jobs. 3) Multiple strategies are helpful, but they do not replace the body’s need for sleep. Strategies for managing drowsy driving and anxiety/stress producing issues were offered.Conclusions: Twelve-night shift workers shared the challenges drowsy driving and anxiety/stress producing issues outside of the work-related duties. Health care administrators may use the results to gain insight for training nurses for the night shift to prevent drowsy driving injuries and fatalities. The results of the study may offer a platform for further investigation that may uncover best-practice strategies for health care administrators staffing other types of 24-hour medical care facilities.
The Expression of Human Telomerase Reverse Transcriptase in Adult Acute Myeloid Leukemia and Its Correlation With Various Clinico-Pathological Parameters
Authors: AlJobori Farah , Jaafar Abdulkareem Mohammad
Published: March 2019

BACKGROUND: Acute myeloid leukemia (AML) is a heterogeneous disorder characterized by clonal expansion of myeloid progenitors (blasts) in the bone marrow and peripheral blood, AML accounts for 80% of acute leukemia in adults, its incidence increase with age. AML can be a fatal disease so research to predict prognosis is important. Telomerase (TA) is an enzyme that stabilizes the telomere length and makes the cell immortal. It is present in some of the normal cells, fetal cells, adult germ cells, and presents in 85% of tumors in humans, it has been shown that TA can be used as a prognostic marker in some solid and hematological neoplasms. Telomere length is a factor that predicts telomere function.

AIM: We test the quantitative amount of human telomerase reverse transcriptase (hTERT) gene expression in AML (diagnosed according to FAB) adult and its correlation with various clinic-pathological parameters.

PATIENTS & METHODS: We used the TRAP assay to assess the hTERT gene expression in mononuclear blood cells from 40 newly diagnosed AML patients, 25 AML patients after completing their course of treatment, and 15 control health subjects.

RESULTS: The mean value of hTERT in AML and control groups were [1.59 ± 1.27 anm and 0.035 ± 0.046 anm respectively], and this difference was significantly higher in patients than in control group (p = 0.0001). The telomerase activity was positive in 27 (67.5%) AML patients, while 13 (32.5%) AML patients were negative for telomerase activity. Twenty-five patients after induction chemotherapy were followed up by bone marrow and peripheral blood examination to determine the patient’s response to therapy. Complete hematological remission was achieved in 12 (48.0%) patients and incomplete hematological remission in 13 (52.0%) patients (14%). The hTERT level was significantly higher in patients before induction chemotherapy than after completion of the induction course (p = 0.0001). The hTERT level at diagnosis in patients who did not achieve complete hematological remission was significantly higher than that in patients who achieved complete hematological remission (p = = 0.026). The hTERT level after induction therapy was significantly higher in patients who did not achieve complete hematological remission than in patients who achieved complete hematological remission (p = 0.003).

CONCLUSION: Our research suggests that the hTERT expression could serve as a prognostic marker for AML patients.

Authors: Öztürk Özden Tepeköylü
Published: March 2019

The aim of this study is to determine the leisure satisfaction levels of students who study sports sciences. In addition, in the study, the satisfaction levels of the students were compared according to their gender, departments and the most preferred activity type in leisure. The research was in quantitative descriptive design and consisted of a total of 379 sports sciences students, including 144 female and 235 men. The “Leisure Satisfaction Scale” developed by Beard and Raghep (1992) which is adapted to Turkish by Gökçe and Orhan (2011) and the “Personal Information Form” developed by the researcher were used as data collection tools. T-test, ANOVA and one-way MANOVA test techniques were used in the analysis of the data. According to the research findings, the leisure satisfaction of the students of Sports Sciences has been observed to be high level. In general, it was found that leisure satisfaction of those who do most physical activity is higher than those who did social, intellectual and artistic etc. activity. According to the gender factor, leisure satisfaction total score did not make a difference, but it was seen that female had higher scores than psychological and relaxation dimensions. In the comparisons between the departments, it was determined that the recreation department had more leisure satisfaction than the coaching and physical education teaching department students. It has been observed that the highest score section is recreation and the lowest score section is coaching. Finally, the research findings were discussed.
Exponential Atlases: A Metaphysical Approach to the Organizational Rapid Growth
Authors: Pompa Leonardo
Published: March 2019

According to Greek mythology, Atlas held up the sky on his shoulders. Nowadays, the term atlas refers to “a book of maps or charts” (1). In this paper, the term is used in both senses. On the one hand, the purpose is to understand the conditions favoring – hold up – the birth and the evolution of exponential organizations. On the other hand, the goal is to draw a concept map that allows us to identify the interactional dynamics among the actors involved in this evaluative process.  In other words, first I'll try to know who “holds up the sky” (static interpretation), and then we will see who “lives in it” (moving interpretation). The idea is that disruptive innovation mediates the relationship between environmental/organizational features (conditions) and exponential growth (phenomenon). So far, little consideration has been given to the favorable conditions that can allow organizations to become exponential. This paper  aims to pave the way for future systematized research on the ExO’s genesis and development.

Explanatory Power of Selected Proxies in Predicting Stock Returns of Large U.K. Companies
Authors: Rodriguez Daniel F. , Malik Ali , Abumustafa Nasser I. , Jamal Arshad
Published: March 2019

Predicting stock returns has been instrumental in our understanding of capital market structure. The validity of models, like the Capital Asset Pricing Model or the Gordon Growth Model, has influenced and contributed to building mathematical representations in predicting required return. Several studies attempted to explore different variables to determine the explanatory power of proxies in predicting stock return. For example, it is reported that dividends can explain up to 25% of the variance in returns. The explanatory power of dividends in the regression analysis showed a significant variation when the analysis follows time-series methodology. This study aims at examining the predicting power in the U.K. equity market by plugging into the regression model some of the variables conventionally measured in the Structural Equation Modeling. The study is quantitative and uses secondary data. The findings of this study suggest that the selected proxies, dividend growth, earnings per share, and beta exhibit weak explanatory power in predicting returns of large U.K. companies.
Optimization of anethole determination using differential pulse voltammetry on glassy carbon electrode, boron doped diamond electrode and carbon paste electrode
Authors: Wójcik Szymon , Jakubowska Małgorzata
Published: March 2019

Voltammetry is the general term for all techniques in which the current is measured as a function of electrode potential. The voltammetric techniques can be applied for the quantitative analysis of inorganic and organic species and are best suited for substances which can be either oxidized or reduced on electrodes. These techniques are characterized by high sensitivity which results in the possibility of performing determinations at a low concentration level. In voltammetry, many different types of working electrodes are applied. One of the important groups are solid electrodes, among which carbon electrodes play an important role. They represent a good alternative to mercury electrodes, however, surface preparation before the usage is required. In this work anethole determination will be presented using three types of carbon electrodes: glassy carbon electrode, boron doped diamond electrode and carbon paste electrode. Optimization process will be also described.

COHESION POLICY INSTRUMENTS SUPPORTING TOURISM DEVELOPMENT
Authors: Dominiak Natalia
Published: March 2019

The aim of the article is to discuss issues related to the development of tourism in the context
of the possibility of financial support available from cohesion policy funds in the current financial perspective
for the years 2014-2020. The particular attention was paid to the multifaceted nature of modern
tourism and the directions of changes in the use of EU funds, referring to the completed programming
period 2007-2013. An attempt was also made to indicate the significance of tourism in the section of the
national economy of Poland and in the European Union, concentrating on its interdisciplinary character.
Characteristics of cohesion policy, its goals and principles of functioning were made. The article is of a
review nature, which means that the authors’ own materials and empirical material from the literature
of the subject were used. The figures were obtained from reports published by the Chancellery of the
Prime Minister of the Council of Ministers. It was found out that the amount of allocated funds for cohesion
policy among all European Union countries in 2014-2020 is the highest for Poland and amounts
to EUR 72.9 billion. There is an increase in the amount of funds allocated from the European Union to
Poland, compared to the amount of allocated funds in the 2007-2013 perspective. It was also pointed
out that the cohesion policy instruments mentioned above only indirectly contribute to the development
of tourism, as the financing for 2014-2020 lacks programs and activities entirely dedicated to tourism.
FINANCIAL EFFICIENCY OF BREEDING AND TRADE OF LUPINE SEEDS IN POLAND
Authors: Jerzak Michał A.
Published: March 2019

This paper presents some partial results of a study on the financial consequences of lupine breeding in Poland, as well as market conditions for seed trade. Analysis also covers the impact of breeding fees on the financial performance of this business. The research procedure was based on a case study of two domestic plant-breeding companies. The study includs the analysis of funding sources used for lupine seed breeding and the potential financial outcomes of this activity. The plant-breeding companies, covered by this study, are owned by the State Treasury and are organized so that the breeding department is part of a larger agricultural undertaking engaged in multiple production activities. Therefore, accounting data of these undertakings was used in order to determine the economic performance of the breeding department. Also, direct interviews were conducted with breeding department employees and top-level managers. A simulation calculation was also performed under the assumption that the breeding department is an independent undertaking which settles its accounts with the holding on a commercial basis. Therefore, the breeding department was assumed to sell intellectual property consisting of seed fraction “E.” The plant-breeding company is also a sort of seed company which sells the marketable seed fraction K. In summary, lupine breeding is concluded to be a highly profitable business, provided that the plant-breeding departments fully settle their accounts internally and that the breeding fees from seed companies are fully collectable. The development and production potential identified in this study suggests these plants could be used to increase national self-sufficiency in vegetable protein.
SENSORY QUALITY OF STRAWBERRY JAMS WITH A PARTICULAR FOCUS OF KASHUBIAN STRAWBERRY JAM
Authors: Korzeniowska-Ginter Renata
Published: March 2019

Applicable legal regulations allow Polish farmers to sell agricultural produce and products
made from them. This activity enables the creation of a new market of natural food, which is competitive
in relation to industrially produced food. The aim of the research was to compare the quality of strawberry
jam available on the market with its counterpart produced on farms. The studies compared the
extract content and sensory quality of 11 strawberry jams available in retail with jam from the Kashubian
Strawberry certified with EU PGI. The content of the extract and intensity of 17 sensory markers characterising
the appearance, consistency, taste and aftertaste of strawberry jam were assessed. The study
was conducted using quantitative descriptive analysis – QDA. The strawberry jam which was compared
was characterized by a very large diversity of sensory characteristics in terms of brightness, opacity,
colour intensity of red and softness. The smaller variation was characterised by an intensity of features
relating to elasticity, acidic and chemical taste as well as sweet, dry and fruity aftertaste. Industrial jams
were similar in terms of quite a perceptible sweet taste and viscosity and average perceptible fruit taste.
The jam obtained from the Kashubian Strawberry was not inferior to the quality of industrial-grade
jam. It stood out in comparison with a high content of extract, attractive red colour and greater softness.
Compared to commercial jams, it had a higher intensity of fruity, sweet and sour taste, and a distinctly
fruity aftertaste, with no foreign notes.

When a problem in a fairy tale challenge and inspire - a study of preschool children’s work on technological solutions
Authors: Svensson Maria , Dahlbäck Katharina , Von Otter Ann-Marie
Published: March 2019

The aim of this study is to contribute with knowledge about children’s practical work and communication in a technology-related problem solving activity, based on a fairy tale. More research about technology in preschool is needed, especially concerning children’s knowledge in relation to the technology (design) process. The study was conducted in a pre-school with two pre-school teachers. Children’s problem solving activities was documented by video recordings on four occasions. The results showed that the children worked with most parts in the technology process. The fairy tale contextualized the problem, sketches were used to communicate ideas and children’s solutions were inspired by the story as well as their experiences from everyday life. Combining the known (the fairy tale) and the unknown (the technology content) proves to be fruitful when solving a technology-related problem where imagination, knowledge and experience is required.
Hands-on science for recently immigrated students: possibilities for language acquisition and motivation for science
Authors: Schmiedebach Mario , Wegner Claas
Published: March 2019

Schools have begun to face many challenges with the influx of recently immigrated students who are not able to speak the official language well enough to participate in class. To help integrate and accelerate language acquisition in German schools, these students are often enrolled in "international classes". Our project, "Biology for Everyone", teaches newly arrived secondary students science through the use of hands-on experiments. While addressing scientific content, students build new language structures and improve their German. Using 13 interviews, the concomitant research examines students’ evaluations of the project in relation to science as well as language acquisition with a qualitative content analysis. Results show that students value this action-oriented approach as it helps them understand scientific concepts. Furthermore, they notice an improvement in their German and an increase in their science content knowledge. Therefore, such "international classes" should be considered for use in additional subjects in order to ease integration into the regular school system.

Creative drama in chemistry education: a social semiotic approach
Authors: Danckwardt-Lillieström Kerstin , Andrée Maria , Enghag Margareta
Published: March 2019

Drama is a way of teaching that has been suggested to support learning, but studies in science education are limited and the potential of using drama needs further scrutiny and design development. In this study, we investigate how creative drama may afford students’ meaning-making of abstract non-spontaneous chemical concepts related to chemical bonding, by exploring what kind of semiotic work students are engaged in when given the opportunity to use their own bodies as semiotic resources.We combine sociocultural theory of learning with multimodal social semiotic analysis. Our results show how creative drama opens up for different types of transductions and transformations that have consequences for students’ meaning-making. A conclusion is that the creative drama activities may afford student exploration of intermolecular forces in new ways in particular when students use bodily mode in combination with other semiotic resources.
Didactic modeling of complex sustainability issues in chemistry education.
Authors: Dudas Cecilia , Rundgren Carl-Johan , Lundegård Iann
Published: March 2019

To meet future challenges regarding sustainability issues, science education needs to address how to educate scientifically literate and responsible citizens. One aspect of this is how to draw students’ attention to the complexity in sustainability issues. Therefore, this study analyses how complexity can become visible in students’ deliberations. The study has been conducted as an in-situ study at two upper secondary schools. The data was analysed using Practical Epistemological Analysis (PEA) and Deliberative Educational Questions (DEQ). The results show that four different kinds of considerations were used to visualise complexity. Those considerations regarded facts and values in relation to known and unknown facts. The considerations were used to develop a didactic model. Design principles were also developed, which together with the model can support teachers in didactic analyses regarding complex sustainability issues in chemistry education. Furthermore, the study shows that chemistry education can contribute to development of Bildung and democratic citizenship.

Summertime é o último volume da trilogia autoficcional Scenes from Provincial Life, de J. M. Coetzee. Esse romance apresenta uma narrativa híbrida: alguns capítulos são narrados em forma de diário e outros, em forma de entrevista. A partir desses dois modos narrativos, nossa hipótese é que a figura do narrador neste romance é mais que contar uma história: ele exerce os papeis (para)literários de autor, leitor e personagens. Neste artigo, discutiremos a problemática contemporânea da arte do narrar e analisaremos quais os efeitos desse(s) narrador(es) múltiplo(s) na narrativa. O narrador em Summertime não está morto, mas é versátil e volátil.

Este trabalho objetiva discutir como a imagem de Autor quadrinístico é formulada no campo discursivo como resultado de práticas de diversos agentes, que contribuem para circulação de enunciados sobre ele e sua Obra. Inicialmente, apresentar-se-ão os conceitos de espaço canônico e espaço associado, propostos por Dominique Maingueneau (2006). Em seguida, buscar-se-á ampliar esses conceitos com foco no discurso quadrinístico, a partir dos conceitos de espaço de sustentação e espaço de recepção (DELORMAS, 2014; COSTA, 2016). Por fim, mostrar-se-á como o conceito de espaço de sustentação contribui para compreender as práticas discursivas responsáveis pelos posicionamentos dos autores no campo quadrinístico.
A AUTOBIOGRAFIA COMO PREPARAÇÃO DA CRÍTICA LITERÁRIA E DA IMAGEM DO AUTOR: MANUEL BANDEIRA E OSWALD DE ANDRADE
Authors: Moreira Daniel Da Silva
Published: March 2019

Este texto tem por objetivo desenvolver uma reflexão sobre a autobiografia como espaço de criação e legitimação de uma imagem desejada de autor e, ao mesmo tempo, de articulação prévia da leitura crítica da obra literária como um todo. Para evidenciar esses processos de legitimação de imagem e de interpretação da obra literária recorre-se às autobiografias de Manuel Bandeira, o Itinerário de Pasárgada, e de Oswald de Andrade, Um homem sem profissão.
“BEHOLD ME IMMORTAL!” AS JANE AUSTENS DO SÉCULO XIX À NOVA NOTA DE DEZ LIBRAS
Authors: Biajoli Maria Clara Pivato
Published: March 2019

O presente artigo faz um mapeamento das diferentes imagens produzidas sobre a escritora inglesa Jane Austen (1775-1817) após sua morte, desde as biografias publicadas por sua família até análises de críticos literários e fãs do século XIX e atuais. Essas imagens são importantes porque impactam a forma como a obra de Austen é interpretada, divulgada e comercializada através, por exemplo, de adaptações cinematográficas e para a televisão. O artigo conclui com uma análise da nova nota de dez libras lançada pelo governo da Inglaterra em homenagem aos duzentos anos da morte da autora.
A CARROÇA E O TREM: FLANNERY O’CONNOR E A LITERATURA SULISTA NORTE-AMERICANA
Authors: Barcala Débora Ballielo , Rapucci Cleide Antonia
Published: March 2019

O presente artigo pretende discutir a posição ambígua ocupada pela escritora estadunidense Flannery O’Connor (1925-1964) na comunidade literária sulista norte-americana. Sua condição de mulher branca a colocava nessa posição ambígua, pois enquanto branca era participante da classe dominante de sua região, mas enquanto mulher era oprimida. Para isso baseamos nosso trabalho em Sarah Fodor (1996), Katherine Prown (2001) e Sarah Gordon (2003). Depois são feitas considerações sobre a recepção e a fortuna crítica da obra da autora nos Estados Unidos para demonstrar como sua obra resiste a rotulações apesar de ter sido interpretada das mais diversas maneiras.
TODA HISTÓRIA COMEÇA IN MEDIA RES: NIETZSCHE E AS CIÊNCIAS DA LINGUAGEM
Authors: Machado Isadora
Published: March 2019

A partir da perspectiva da História das Ideias Linguísticas, investigamos as filiações a Friedrich Wilhelm Nietzsche nas Ciências da Linguagem. A hipótese do trabalho é a de que a enunciação nietzscheana é um acontecimento na história da reflexão sobre a linguagem. Compreende-se o acontecimento, tal como o define Eduardo Guimarães: não enquanto um fato no tempo, mas como aquilo que produz diferença em sua própria ordem. Tomada como acontecimento, a enunciação nietzscheana instaura sua própria diferença, e nela consideramos duas temporalidades distintas: por um lado, a que produz a filiação de Edward Sapir a Nietzsche, e que recorta Wilhelm von Humboldt como memorável; por outro, a que produz a filiação de Michel Pêcheux e Eni Orlandi a Nietzsche. A possibilidade de pensar as temporalidades em sua equivocidade demonstra que há um caminho na reflexão sobre a linguagem a ser trilhado nas sendas de um materialismo trágico – a consideração de que a determinação histórica não é fruto de um processo maquínico, motorizado, mas que há algo do acaso que comparece.

NOTA SOBRE A NOÇÃO DE CULTURA E SUA RELAÇÃO COM A DE CIVILIZAÇÃO: O OCIDENTE COMO OBSERVATÓRIO DAS FORMAS DE VIDA SOCIAL
Authors: Rodríguez-Alcalá Carolina
Published: March 2019

Um aspecto central no conhecido debate em torno dos termos civilização e cultura surgido na Europa entre os séculos XVII e XVIII é o olhar mais prescritivo ou descritivo que eles projetam sobre as formas de vida social e seus efeitos na constituição de conceitos que são fundamento das ciências sociais modernas, em particular, da Antropologia. Embora não sem ambivalências, entrecruzamentos e superposições de significação, existe um certo consenso em associar civilização a uma perspectiva eurocêntrica, que tomaria as formas de vida ocidentais como modelo; a invenção do conceito moderno de cultura teria coincidido com o questionamento dessa perspectiva e a constituição de uma postura mais neutra, que definiria toda e qualquer forma de vida como uma entidade coerente e autônoma, que pode e dever ser analisada a partir de categorias próprias. O objetivo do presente trabalho é problematizar essa ideia, sustentando que tanto um como outro termo atualizam, através de percursos de sentido diferentes, uma memória urbana ocidental, a partir das quais são descritas – e hierarquizadas — as diferentes sociedades, o que afetará a constituição tanto do senso comum (os sentidos das palavras) como das ciências (os sentidos dos conceitos). Nosso intuito, com isso, é reconhecer a historicidade de nossas ideias sobre a natureza humana e sua diversidade, sustentando que o olhar é sempre situado no tempo e no espaço e afetado pelas condições políticas particulares em que se inscreve.
MANUALIZAÇÃO E DISCIPLINARIZAÇÃO DOS SABERES DA LÍNGUA: O CASO DA ENUNCIAÇÃO
Authors: Puech Christian
Published: March 2019

O processo de manualização dos saberes linguísticos concernentes à Enunciação é considerado sob um duplo aspecto:  por um lado, as modalidades segundo as quais as teorias da Enunciação, em sua diversidade mesma, emergiram historicamente em uma proximidade problemática com a linguística estrutural: por outro lado, sua integração universitária/escolar progressiva, submetida a outras restrições e transplantadas para uma outra história. É na interseção dessas duas “contextualizações” que o “manual” manifesta sua especificidade em relação às “obras eruditas”. É em torno da noção complexa de transmissão que se coloca em relação à história das ideias linguísticas, de um lado, e a implementação operatória escolar, de outro.  De acordo com quais procedimentos? Com quais efeitos? Mas sobretudo aqui: em que condições?

O presente texto é uma tradução (francês-português) da “Introdução” do Cours de Linguistique Générale (CLG). Essa introdução foi elaborada por Tullio De Mauro em 1967 para a versão italiana do CLG. Em 1972, a introdução, as notas e os comentários de Tullio De Mauro para a edição italiana passaram a fazer parte da edição francesa. A tradução aqui apresentada tem como base a publicação francesa do CLG de 1974, a qual reproduz em sua totalidade e com a mesma paginação, a edição publicada precedentemente pela editora Payot. Por tratar-se de uma introdução de uma obra, decidimos não dar outro título ao texto aqui traduzido, uma vez que também não caberia, nesse lugar, chamá-lo de “introdução”, ainda que não deixe de ser a “introdução” do CLG.A presente tradução foi autorizada à Professora Dr. Amanda Eloina Scherer pelo próprio autor, Professor Dr. Tullio De Mauro, durante um jantar informal acontecido em Paris, após sua conferência intitulada «Sisyphe. Interaction, interruption, intégration dans la transmission des savoirs scientifiques sur le langage des langues», realizada em 05 de junho de 2015, na École Normale Supérieure de Paris, organizada pelo Institut de Textes et Manuscrits Modernes (ITEM), sob responsabilidade do Professor Dr. Giuseppe D'Ottavi. A referida conferência pode ser assistida no seguinte endereço:A tradução aqui apresentada foi realizada por Maria Iraci Sousa Costa e Amanda Eloina Scherer.Aproveitamos o espaço, também, para agradecer ao Professor Giuseppe D'Ottavi por sua leitura atenta e cuidadosa da tradução que ora apresentamos ao público brasileiro. Ficamos por demais lisonjeadas em poder contar com o apoio e o incentivo de um discípulo do mestre italiano que, ao lado do mestre genebrino, nos inspiram com suas ideias que ultrapassam fronteiras e oceanos e resistem ao tempo.
AS REVISTAS CIENTÍFICAS E A DISCIPLINARIZAÇÃO DOS ESTUDOS LINGUÍSTICOS NO BRASIL
Authors: Schneiders Caroline Mallmann
Published: March 2019

No presente estudo, refletimos sobre a importância das revistas científicas para a produção, circulação e legitimação do conhecimento linguístico no Brasil. Para nós, nas revistas, não há apenas a divulgação do conhecimento, mas também a relação entre o conhecimento e a comunidade científica, e esta contribui para a legitimação do saber entre seus pares. Nesta reflexão, mobilizamos a Revista Brasileira de Filologia, analisando a sua contribuição para a legitimação do domínio de saber da Linguística. Para tanto, filiamo-nos aos pressupostos da História das Ideias Linguísticas e da Análise de Discurso. Assim, partindo da relação entre circulação e legitimação, a qual, por sua vez, instaura as filiações de sentidos, entendemos que são, sobretudo, essas filiações que fazem os saberes se institucionalizarem e circularem em dada conjuntura sócio histórica e ideológica.
