Comparative study between ground-based observations and NAVGEM-HA analysis data in the mesosphere and lower thermosphere region
Authors: Stober Gunter , Baumgarten Kathrin , McCormack John P. , Brown Peter , Czarnecki Jerry
Published: October 2020

Abstract. Recent studies have shown that day-to-day variability of the migrating semidiurnal solar (SW2) tide within the mesosphere and lower thermosphere (MLT) is a key driver of anomalies in the thermosphere–ionosphere system. Here, we study the variability in both the amplitude and phase of SW2 using meteor radar wind and lidar temperature observations at altitudes of 75–110 km as well as wind and temperature output from the Navy Global Environmental Model – High Altitude (NAVGEM-HA), a high-altitude meteorological analysis system. Application of a new adaptive spectral filter technique to both local radar wind observations and global NAVGEM-HA analyses offers an important cross-validation of both data sets and makes it possible to distinguish between migrating and non-migrating tidal components, which is difficult using local measurements alone. Comparisons of NAVGEM-HA, meteor radar and lidar observations over a 12-month period show that the meteorological analyses consistently reproduce the seasonal as well as day-to-day variability in mean winds, mean temperatures and SW2 features from the ground-based observations. This study also examines in detail the day-to-day variability in SW2 during two sudden stratospheric warming, events that have been implicated in producing ionospheric anomalies. During this period, both meteor radar and NAVGEM-HA winds show a significant phase shift and amplitude modulation, but no signs of coupling to the lunar tide as previous studies have suggested. Overall, these findings demonstrate the benefit of combining global high-altitude meteorological analyses with ground-based observations of the MLT region to better understand the tidal variability in the atmosphere.

Abstract. Nitrous acid (HONO) is a significant precursor of atmospheric
“detergent” OH radicals and plays a vital role in tropospheric chemistry.
The current knowledge about daytime HONO sources is incomplete, and its
impact on the tropospheric radical chemistry has not been fully quantified.
Existing observational studies of HONO were mostly conducted at the surface,
with few efforts focusing on the high-elevation atmosphere. In order to
better understand the characteristics and sources of HONO in the upper
boundary layer and lower free troposphere, two intensive field observations
were carried out at the summit of Mt. Tai (1534 m a.s.l.), the peak of the
North China Plain (NCP), in winter 2017 and spring 2018. HONO showed moderate
concentration levels (average ± standard deviation: 0.15±0.15
and 0.13±0.15 ppbv), with maximum values of 1.14 and 3.23 ppbv in
winter and spring, respectively. Diurnal variation patterns with broad
noontime maxima and lower nighttime concentrations were observed during both
campaigns, which is distinct from most of the previous studies at the ground
level. The Lagrangian particle dispersion model (LPDM, WRF-FLEXPART v3.3) simulations indicated the combined effects of the
planetary boundary layer evolution and valley breeze on the daytime HONO
peak. A photostationary state (PSS) analysis suggested a strong unknown
daytime HONO source with production rates of 0.45±0.25 ppb h−1 in
winter and 0.64±0.49 ppb h−1 in spring. Correlation analysis supported
the important role of photo-enhanced heterogeneous conversion of NO2 to
HONO on the aerosol surface at this high-elevation site. HONO photolysis is
the predominant primary source of OH radical and plays a major role in the
radical chemistry at Mt. Tai. The model only considering a homogenous HONO
source predicted much lower levels of the HOx radicals and atmospheric
oxidation capacity than the model constrained with measured HONO
data. This study sheds light on the characteristics, sources, chemistry, and
impacts of HONO in the upper boundary layer and lower free troposphere in
the NCP region.
Coherence of Global Hydroclimate Classification Systems
Authors: McCurley Pisarello Kathryn L. , Jawitz James W.
Published: October 2020

Abstract. Climate classification systems are useful for investigating future climate scenarios, water availability, and even socioeconomic indicators as they relate to climate dynamics. These classification systems typically utilize various forms of water and energy indicators to create zone boundaries. However, there has yet to be a classification framework that includes evapotranspiration (ET) rates as a governing principle, nor has there been an effort to simultaneously compare the structure and function of multiple existing classification schemes. Here, we developed three new classification systems based on ET rates and one new system based on precipitation and potential evapotranspiration, and we compared these four new systems against four previously established climate classification systems. The within-zone similarity, or coherence, of long-term water budget components was evaluated for each system based on the premise that the application of a climate classification framework should correspond to those variables that are most coherent. Additionally, the complexity of zone boundaries in each system was assessed. The most frequently used system, Koppen-Geiger, had high hydroclimate coherence but also high spatial complexity. This study produced classification systems of improved coherence for individual water budget components, lower spatial complexity, and fewer parameters needed for their construction. The Water-Energy Clustering classification system is the primary framework proposed here for future investigations in which regions of interest include zones of differing hydrologic dynamics.

Abstract. Earlier studies have demonstrated that soil texture and geochemistry strongly affect soil organic carbon (SOC) content. However, those findings primarily rely on data from temperate regions with soil mineralogy, weathering status and climatic conditions that generally differ from tropical and sub-tropical regions. We investigated soil properties and climate variables influencing SOC concentrations across sub-Saharan Africa. A total of 1,601 samples were analyzed, collected from two depths (0–20 cm and 20–50 cm) at 45 sentinel sites from 17 countries as part of the Africa Soil Information Service (AfSIS) project. The dataset spans climatic conditions from arid to humid and includes soils with a wide range of pHH20 values, weathering status, soil texture, exchangeable cations, extractable metals and a variety of important land cover types. The most important SOC predictors were identified by linear mixed effects models, regression trees and random forest models. Our results indicate that SOC is primarily controlled by aridity index (PET/MAP), exchangeable calcium (Caex) and oxalate-extractable aluminum (Alox); this was found across both depth intervals. Oxalate-extractable iron (Feox) emerged as the most important predictor for both depth intervals in the regression tree and random forest analyses. However, its influence on SOC concentrations was strong only below Feox concentrations of 0.25 wt %. This suggests that Feox can act as a pedogenic threshold – even on a continental scale. Across model-ling approaches, clay and fine silt content (
Ethical dilemmas in field placements: The experiences of social work students in Norway and possible implications for social work education
Authors: Eriksen Heidi Lie , Gradovski Mikhail
Published: October 2020

The study reported in this paper focuses on social work students’ experiences of ethical challenges, including dilemmas, during their field placements. Moreover, drawing on dialogical approach and the results of the thematic analysis, the authors discuss what ethical dilemmas the students experience during their in-field practice, and what implications the handling of these ethical dilemmas can have for the organization of social work education. The findings that are reported in this article are the results of the analysis of six sets of data collected with the help of interviews. The interpretive framework used in this study is a dialogical approach. The research strategy has been a qualitative approach, and the data collection has taken place in semi-natural settings. The thematic analysis of the data lead to four major themes of ethical challenges that the students experienced in their field placements. The first theme concerns structural conditions on a macro level that the students were confronted with when in practice. The second theme is about ethical challenges due to the students´ lack of knowledge and experience in the field. The third theme presents challenges in direct work with service users related to the students´ awareness of values and perspectives. The fourth theme concerns ethical challenges that occurred when students interacted with others in the organizations where the field placements took place. We argue that due to the fact that the authorial agency of any learner consists of personal attitudes, goals, values, knowledge, competences, and skills, it is important to organize supervision activities in a way that allows discussions in free and fearless environments so that the student could learn and unlearn knowledge and skills. This means that in-field placements should be viewed as learning arenas for various types of knowledge and skills, including knowledge on themselves, and not just places where the students can gain only strictly professional practical knowledge and try out their theoretical knowledge.

Authors: Shujat Faiza
Published: October 2020

The purpose of the present paper is to prove some results concerning symmetric generalized biderivations on prime and semiprime rings which partially extend some results of Vukman \cite {V}. Infact we prove that: let $R$ be a prime ring of characteristic not two and $I$ be a nonzro ideal of $R$. If $\Delta$ is a symmetric generalized biderivation on $R$ with associated biderivation $D$ such that $[\Delta(x,x), \Delta(y,y)]=0$ for all $x,y \in I$, then one of the following conditions hold\\ \begin{enumerate} \item $R$ is commutative. \item $\Delta$ acts as a left bimultiplier on $R$. \end{enumerate}

Published: October 2020

Let $A$ be a generator of an $\alpha-$times integrated semigroup$(S(t))_{t\geq 0}$. We study the uniform ergodicity of $(S(t))_{t\geq 0}$ and we show that the range of $A$ is closed if and only if $\lambda R(\lambda,A)$ is uniformly ergodic.Moreover, we obtain that $(S(t))_{t\geq 0}$ is uniformly ergodic if and only if $\alpha=0$. Finally, we get that $\frac{1}{t^{\alpha+1}}\int_{0}^{t}S(s)ds$ converge uniformly for all $\alpha\geq 0$.

By employing generalizations of Gauss's second, Bailey's and Kummer's summation theorems obtained earlier by Rakha and Rathie, we aim to establish unknown Laplace transform of six rather general formulas of generalized hypergeometric function 2F2[a,b;c,d;x]. The results obtained in this paper are simple, interesting, easily established and may be useful in theoretical physics, engineering and mathematics. Results obtained earlier by Kim et al. and Choi and Rathie follow special cases of our main findings.
The Significance of Non-traditional and Alternative Assessment in English Language Teaching: Evidence From Literature
Authors: Mansory Mazin
Published: October 2020

Assessment is an integral part of teaching and learning in educational organizations that requires teachers to prepare tests in order to evaluate their learners’ performance. In language teaching contexts, traditional assessment often evaluates learners’ knowledge of previously learned language items. It is a mandatory process that determines the progress of language learners and the effectiveness of teaching/learning materials. This theoretical article reviews the literature on the notion of traditional assessment or static assessment which has certain shortcomings. Owing to the various drawbacks of static assessment, the review of related literature on the topic highlights and proposes alternative assessment methods, such as authentic assessment, dynamic assessment, peer assessment, and self-assessment.  In contrast to traditional assessment, these different forms of alternative assessment share a common purpose that is to provide language learners with an opportunity to reflect on their strengths and weaknesses and set their future learning goals. The most common of the assessment methods that encourage learners' reflection were peer assessment and self-assessment which involve learners to assess their own progress as well as engage with peers in classrooms to give each other feedback on their language learning tasks assigned by teachers. The studies reviewed in this article illustrate that alternative assessment methods in the form of peer and self-assessment have a positive influence on the language learners' performance and their learning outcomes.

Published: October 2020

Employability of graduates has become a matter of grave concern in Malaysia where the high unemployment rate of graduates is said to be a result of poor English communication skills. English communication plays an important role in an organisation and is said to enhance efficiency and productivity. English communication is therefore, a critical skill for graduates seeking employment, regardless of position or industry. The importance of English communication skills for graduates in the Malaysian private sector and recommendations for improvement initiatives were the focal points of this study. Data was collected from in-depth interviews with 10 employers in the private sector who are in leadership positions, who recruit and manage graduates. The interview transcripts were analysed using ATLAS.ti a Computer Assisted Qualitative Data AnalysiS (CAQDAS) and the findings of the study strongly indicate that employers in the private sector place high value on English communication competency. The results also revealed that mastery of this skill enhances employability of graduates and also creates opportunities for career advancement. The findings further point towards the importance of deeper collaboration between Higher Education Institutions (HEIs) and industry, graduate training and coaching.
Non-Performing Loans and Its Impact on the Banking Sector: An Investigation on the Current Status of Bangladesh
Authors: Abedin Md. Joynal
Published: October 2020

Non-performing loans (NPLs) have become a frustrating issue for the financial institutions in Bangladesh. Our banking industry and the economy in general have taken a negative turn due to the increasing volume of NPLs. This paper aims to investigate the current status of NPLs in the banking industry of Bangladesh. The analysis uses the published data which have been congregated from the annual reports of Bangladesh Bank, websites of the scheduled banks of Bangladesh and the World Bank observed from 2008 to 2019. The study identified that for the last two decades, NPLs are the burning problems for the banks in Bangladesh. Worldwide the standard of NPLs is 2% or less but in our country, it is much intricate. The NPLs percentages in Bangladesh are 4 to 5 times higher than the standard which is disquieting for the entire banking industry. Based on the current investigation, it has been observed that the NPLs ratio is increasing unremittingly with the advancement of time. So, as a financial regulator, the central bank of the country (Bangladesh Bank) must give more emphasize to compactly control the NPLs of the country. This paper contributes by employing new dataset from Bangladesh.

Published: October 2020

This study investigates the effects of psychodrama on adults’ anxiety and subjective well-being levels. A pre/post-test experimental pattern is used with experimental and control groups. The study sample consists of 24 non-thesis master’s program students at Gaziantep University, Human Psychology, and Communication. The State-Trait Anxiety Inventory (STAI) and the Subjective Well-Being Scale were applied as a pre-test to the experimental and control groups. The psychodrama group practice was performed with the experimental group once a week for eleven weeks, 90 minutes per session, while the control group did not receive any practice. After the application, the post-test was administered to both groups. The data were analyzed with SPSS 23 statistical program. The Mann-Whitney U test was used to evaluate the difference between the experimental and control group, and the Wilcoxon Signed Rank Test was applied for the changes within the experimental group. The findings indicate that the individuals’ anxiety level in the experimental group significantly decreased compared to the control group. There was no significant difference between subjective well-being in the experimental and control group for pre-test and post-test applications.
Determining the Attachment Styles of Football Coaches to Their Athletes
Authors: Kayhan Recep Fatih
Published: October 2020

In this study, it was aimed to determine the attachment styles of soccer trainers to their athletes according to various variables. The relationship between the trainers and their athletes is an important element to act in line with the goals, in this context, determining the attachment styles will create an awareness for the trainers and will provide support for the development of the trainers in order to raise successful and mentally healthy athletes in the long term. The research sample consists of 406 licensed male football coaches who are actively performing as trainers in football at different levels and age groups. In the study, a questionnaire was created using the trainer-athlete attachment scale to determine the personal information form attachment styles to collect the demographic characteristics of football coaches. SPSS 25 program was used to analyze the data. It was determined that the data were distributed normally, and the t-test and the One-way ANOVA test was used to compare independent groups. Tukey test was used as a complementary post-hoc analysis to determine the difference after the ANOVA test. The significance level in the analyses was determined to be p <0.05. While there was a significant difference in attachment styles of the trainers according to marital status, number of weekly training and years of coaching; no significant difference was found according to the variables of age, education level and coaching level. As a result, it was found that coaches who are married and train 6 times and more in a week have good problem-solving skills in their interpersonal relationships, have a positive approach to problems, are constructive while solving problems, are self-confident, do not evade responsibility, and have an insistent attitude in solving problems. Trainers can help athletes develop their positive emotions and life satisfaction with healthy evaluations and positive/optimistic thoughts. It is thought that the sharing environment that develops as a result of the cooperation and efforts made in line with common goals in sports environments, especially in training, increases the level of coach-athlete relationship.
Análisis vegetacional del bosque nativo en la región mediterránea de la zona central de Chile: zona de estudio valle de Colliguay
Authors: Arancibia Fortes Javier , Araya Silva Juan Luis , Zunino Mardones Daniel
Published: October 2020

El bosque esclerófilo de la zona central de Chile no solo otorga servicios ecosistémicos y/o paisajísticos, sino que es un hotspot de biodiversidad con un alto grado de endemismo, lo cual le confiere atributos ecológicos únicos. El objetivo del presente trabajo fue analizar y cuantificar los parámetros de diversidad vegetacional del bosque esclerófilo de Colliguay con el fin de dar a conocer su patrimonio natural, y construir un marco referencial y conceptual para futuros planes de conservación de especies nativas. Para llevar a cabo el estudio se efectuó un dimensionamiento mediante sistemas de información geográficos (SIG) del bosque esclerófilo, en el cual se efectuaron transectos de 100 metros en laderas de solana y umbría haciendo un catastro de la flora existente y catalogándola según taxonomía, origen y estado de conservación. Posteriormente se efectuó un perfil de especies para cada ladera, analizando la riqueza y abundancia. Los resultados indicaron un alto grado de endemismo, así como la presencia de especies en peligro de extinción. Además, hubo claras diferencias ecológicas entre las laderas de solana y umbría cuyas condiciones físicas son determinantes en la distribución de las especies vegetales. A pesar de la fragmentación existente, los parches de bosque esclerófilo continúan manteniendo su identidad con especies con marcada afinidad a la luminosidad y la sombra, lo cual es un indicio de la resiliencia existente en este sector de la región de Valparaíso. La evidencia demuestra que este bosque es un remanente de primitivos bosques por lo que necesita mecanismos de protección y conservación.
Cohesión social como base del mejoramiento de la gobernanza en asentamientos informales
Authors: Sarmiento Juan Pablo , Castro Correa Carmen Paz , Sandoval Vicente , Hoberman Gabriela
Published: October 2020

Ante el incremento de asentamientos informales a nivel mundial y especialmente en la región de Latinoamérica y el Caribe (LAC), surge un interés particular para estudiar la gobernanza existente en la informalidad urbana. Luego de una extensa revisión de literatura se contrastan dos casos de estudio, uno de Chile y otro de seis países de LAC. Tradicionalmente, la gobernanza se analiza a través de las relaciones y mecanismos de coordinación entre actores gubernamentales y no gubernamentales, sociedad civil, organizaciones de base y sector privado; y en menor proporción en las relaciones al interior de un mismo grupo de actores, particularmente el de base comunitaria. En los asentamientos informales, por definición, se observa un distanciamiento o desconexión entre los actores no gubernamentales y gubernamentales, en donde estos últimos están prácticamente ausentes y cuyo espacio es ocupado por mecanismos de gobernanza orgánicos y espontáneos que toman control de las decisiones. Estudios recientes apuntan hacia la cohesión social y la membresía asociativa como mecanismos que permiten dimensionar cualitativa y cuantitativamente los tipos y niveles de gobernanza que surgen en áreas donde predomina la informalidad urbana, acompañada de precariedad y de la indiferencia de los actores gubernamentales. Intervenciones dirigidas a la reducción de riesgo de desastres en asentamientos informales demuestran un nivel de incidencia positiva en la dimensión de cohesión social, así como una transformación en la relación entre actores que ha resultado en un empoderamiento de las comunidades, una disminución de la indiferencia gubernamental, y un fortalecimiento de la resiliencia y la gobernanza.

Knowledge management is one of the essential processes in every organization because knowledge is recently considered an important asset that needs to be managed. However, in Thailand, it was observed that in many organizations more importantly the academe, knowledge management processed are not yet at fully implemented and employees are not really fully aware of the KM processes in their workplace. This research reviewed the status of knowledge management (KM) in the IQAN- member college and universities in Thailand based on the interpretation of the practice of their rank and file staff. This study was able to find out the majority of the staff know about KM and view it as essential and strategic part of their institutions. They consider their HEIs as knowledge –based. Furthermore, most of the staff believe that KM in the HEIs are still in introductory, intermediate and some consider that KM is their institution is its growth stage and rated differently their institutes’ KM practice from adequate, good to very good. The staff also affirmed that there is knowledge creation, storage, sharing and transfer via various modes. However, in the preference of use of technology tools, the rank and file staff least prefer the usage of the technology in KM management and prefer the use of communities of practice in the sharing of knowledge. It is therefore, strongly recommended that there should be continuous and cyclic process in KM wherein review of the different stages will be done regularly to update the staff especially in the use of technology because it is a very important tool in knowledge storage and sharing or communicating knowledge.

Given the importance of Public Policies for social transformation, the document explains why and under what circumstances they constitute a decisive factor to promote or inhibit social transformation. A policy is a purposeful, intentional, planned behavior, not just reactive, casual. It is set in motion with the decision to achieve certain objectives through certain means: it is an action with meaning. It is a process, a course of action that involves a whole complex set of decisions and operators. Politics is also a public communication activity. Hence, the purpose of this article is s be a guide in the understanding and analysis of what is meant by Public Policies, as well as contributing to the understanding of the mechanisms for their design and elaboration. That they have a clear and simple idea of what Public Policies are in a generalized context and the steps that must be carried out to implement them.

Published: October 2020

The purpose of this study is to reveal the views of administrators on the assessment of education administrators within the context of ethical values and their reflection on organizational culture. Ten administrators who were determined using convenience sampling which is one of purposeful sampling methods, participated in the study which was conducted using qualitative research method. Qualitative research technique was used in the research and it is used in one of the qualitative research designs, phenomenological design. Considering in terms of education administration; ethical rules to be possessed by today’s school administrators were tried to be revealed on the basis of key concepts such as Plato’s “wisdom, courage, moderation and justice” concepts and Kant’s “duty, principle, will power, liability, law and rule” concepts according to his deontological theory, in accordance with the results acquired during the interview based on the application. According to the results of the research, it is possible to say that Plato's four key concepts of “Wisdom, bravery (courage), measure and justice.” Are adopted more by school administrators. It is seen that the virtues of flour are generally adopted but in practice, Kant's Deontological theory is put into practice. In addition, it is considered that every step in the direct management of the characteristics of the school administrator and the effects of the administrator in the ethical context directly affect the organizational climate.

The adjustment in the growing season associated with cultural practices can mitigate the negative effects of salinity on crop production. In this context, the objective of this study was to evaluate the production components of watermelon cv. Crimson Sweet under the effects of irrigation with saline water, soil cover and potassium doses in crops during dry and rainy seasons. The treatments were arranged in a split plot with 2 x 2 x 4 scheme, with the electrical conductivity of the irrigation water (0.3 and 3.0 dS m-1) in the main plot, and the combinations between soil mulch (without and with) and doses of potassium (0, 40, 80 and 120 kg ha-1 of K2O) in the subplots, distributed in randomized blocks. Final stand, number of fruits per plant, average fruit weight, production per plant and yield were evaluated. The data were subjected to analysis of variance and potassium doses were evaluated by regression. In the rainy season, watermelon was more productive than in the dry season even under irrigation, with higher number of fruits and production per plant and yield. Irrigation using water with electrical conductivity of 3.0 dS m-1 should be used with moderation in watermelon crop, as it did not compromise yield. Potassium chloride application is not recommended in soil with intermediate potassium content, because it reduced the number of fruits per plant and yield. The use of mulch is recommended in watermelon cultivation, since it increased the number of fruits and production per plant.

The antagonistic activity of 25 saprobe fungi from semiarid areas of Northeast Brazil was evaluated against Sclerotinia sclerotiorum (Lib.) de Bary (Helotiales: Sclerotiniaceae). Four fungi [Myrothecium sp. Tode (Hypocreales: Stachybotryaceae) isolate 2, Volutella minima Höhn. (Hypocreales: Nectriaceae), Phialomyces macrosporus P.C. Misra & P.H.B. Talbot (Pezizomycotina) and Dictyosporium tetraseriale Goh, Yanna & K.D. Hyde (Pleosporales: Dictyosporiaceae)] were selected and further tested their ability to inhibit mycelial growth, sclerotia formation and ascospore germination of S. sclerotiorum and to control white mold on soybean plants. V. minima and P. macrosporus filtrates at 50% effectively suppressed mycelial growth and Myrothecium sp. isolate 2 completely suppressed sclerotia formation and inhibited ascospore germination by over 95%, the same result as commercial fungicide fluazinam. Soybean plants pre-treated with Myrothecium sp. isolate 2, P. macrosporus, and V. minima and inoculated with S. sclerotiorum showed a reduction of 55.8%, 79.7%, and 83.2% of area under disease progress curve (AUDPC) of white mold, respectively, in relation to water. Collectively, these results underline the antagonistic activity of V. minima, P. macrosporus, and Myrothecium sp. isolate 2 against S. sclerotiorum and their potential as biocontrol agents of soybean white mold.

Beet is a traditional root consumed worldwide and is considered a potential source of several bioactive compounds, yet during production and commercialisation activities, its leaves and stalks are discarded. The beet residue has notable quantities of diverse phenolic compounds that are not taken advantage of it. The beet stalks (sample) were obtained from a local producer at the municipality of Marechal Cândido Rondon, Paraná state, Brazil. The optimisation of the extraction process of antioxidant capacity compounds from beet stalk was done by response surface methodology (RSM), with three independent variables (time, from 5 to 85 min; temperature, from 20 to 80 °C and solvent, from 0 to 100% of ethanol/water ratio). Extracts were evaluated for their reducing capacity, measured by the Folin–Ciocalteu method, and antioxidant capacity by the ability to scavenge DPPH and ABTS free radicals. The optimal global extraction conditions determined were 5 min, 80 °C and 50% ethanol, yielding 13.157 mg gallic acid equivalents (GAE) g–1, 21.539 mol Trolox equivalents g-1 (TE; DPPH) and 250.190 ?mol TE g–1 (ABTS). Beet stalk demonstrated to be an alternative and rich source of recovering of natural antioxidant compounds, showing higher contents when compared to other agro-industrial residues.

Objective: Glutamate-induced excitotoxicity has a role in the pathophysiology of neurodegenerative disorders. Lamotrigine, an
antiepileptic drug, also used to treat bipolar disorders, may be protective against excitotoxic insult. The aim of the study was to
investigate the neuroprotective effect of lamotrigine against the glutamate excitotoxicity in SH-SY5Y cell line.
Materials and Methods: SH-SY5Y human neuroblastoma cells were pre-treated with lamotrigine (50-100-150 μM) prior to exposure
to 15 mM glutamate. The 3-(4,5-dimethythiazol – 2-yl)-2,5 – diphenyl tetrazolium bromide (MTT) assay was performed to determine
cell viability. The anti-oxidant effect of lamotrigine and the role of inflammatory parameters were determined by measuring superoxide
dismutase (SOD), hydrogen peroxide (H2O2), IL-1β, IL-6 and TNF-α.
Results: Intracellular calcium levels and lactate dehydrogenase (LDH) activity increased in glutamate exposed cells. Pre-treatment of
cells with MK-801 showed no protective features against glutamate excitotoxicity. Treatment with 100 μM lamotrigine was effective
in increasing the viability of glutamate exposed cells and in reducing H2O2 increase in these cells. The SOD activity increased by
lamotrigine treated cells exposed to glutamate. IL-1β, IL-6 and TNF-α levels increased after induction with glutamate and attenuated
by lamotrigine.
Conclusion: Overall, our results confirmed the critical role of inflammation and oxidative stress in glutamate-induced excitotoxicity
and lamotrigine may exert a protective effect.

Published: October 2020

O presente ensaio é uma reflexão a partir de algumas experiências de pesquisa em saúde com abordagem cartográfica e registros em diário de campo. Mais do que um mero instrumento de registro, o diário cartográfico é um material empírico multimeios, multilínguas, multivozes e, especialmente, multitempos, narrativa coletiva das afetabilidades, ferramenta singular-coletiva produzida no encontro. Registrar uma pesquisa cartográfica é adentrar uma dimensão temporal, um agir intuitivo que atualiza o passado porque é escrita “de dentro” dos encontros, e inclui as vozes dos sujeitos. Na cartografia a presença do narrador no texto não é viés, mas condição, havendo diferentes modos de entrada, de coautoria narrativa ou vistas dos pontos de vista. Utiliza-se de qualquer variação de qualquer dos três modos discursivos principais para se citar o outro: o discurso direto, o indireto ou o indireto livre, mas especialmente este último, porque possibilita uma máxima interferência de discurso.
Los títulos de crédito: Su rol como packaging y huella visual de la película

Published: October 2020

Los títulos de crédito, como primer y último punto de contacto entre film y espectador, podrían comportarse como packaging de la película. El objetivo de esta investigación es analizar las secuencias de títulos de créditos de una muestra de películas internacionales y diferenciar los elementos gráficos que identifican su rol como embalaje y huella visual. Se plantea una triangulación metodológica apoyada en un microanálisis de los atributos primarios que intervienen en su diseño, y una encuesta para contrastar tales datos. Los resultados infieren que, efectivamente, los créditos funcionan como packaging y marca del film, al facilitar su identificación y diferenciación, y conectar emocionalmente con el consumidor.

Introduction: The purpose of this study was to determine the incidence of radiation induced hypothyroidism after treatment with radiotherapy alone or in combination with surgery/chemotherapy in head & neck cancer patients.
Methods: This study was a retrospective non-randomized done on 100 patients of head & neck cancer in whom definitive radiotherapy, postoperative radiotherapy or radiotherapy in combination with chemotherapy was given. Values of TSH, T3 & T4 were analyzed at baseline and at 6 monthly follow up. Subclinical hypothyroidism was defined as TSH value of >4mU/L and Clinical hypothyroidism was taken as TSH >10mU/L with decreased T3 & T4.
Results: Out of 100 patients 73 patients were euthyroid at the end of 2 year follow up, 21% had subclinical hypothyroidism and 6% had clinical hypothyroidism. Incidence of subclinical hypothyroidism in surgery plus radiotherapy group and radiotherapy group was 22.3% & 50% respectively. Incidence of clinical hypothyroidism in surgery plus radiotherapy group and radiotherapy group was 6.5% & nil respectively.
Conclusion: The incidence of hypothyroidism is high in head & neck cancer patients receiving radiotherapy. The risk is higher in patients who undergo surgery in combination with radiotherapy. Regular thyroid function test is, therefore, recommended.

Análise geográfica para a cidade de Arapiraca/AL sob a perspectiva dos indicadores de Vulnerabilidade Socioambiental
Authors: Santos Juliete , Oliveira Leandro Antonio , Lopes José Lidemberg de Sousa
Published: October 2020

O presente trabalho busca levantar uma discussão referente à vulnerabilidade socioambiental em Arapiraca. Para a classificação da vulnerabilidade, utilizou-se como fonte os dados secundários, disponibilizados pelo Instituto Brasileiro de Geografia e Estatística – IBGE, Censos Demográficos – 2000 e 2010. O parâmetro metodológico utilizado teve como base as técnicas de aferimento de dados censitários, sobreposição cartográfica, trabalhos de campo e o Índice Final de Vulnerabilidade Socioambiental - IFVSA (IPEA, 2015) e Lopes (2013), com quem concordamos, quando diz, que ao analisar a vulnerabilidade socioambiental é importante que sejam verificadas questões ambientais e socioeconômicas pertinentes as ações exercidas na área de estudo. De tal modo, foram quantificados critérios e indicadores preestabelecidos para obter uma média aritmética, chegando ao resultado final para o IVSA. Com o intuito de dar suporte à metodologia adotada para o estudo da vulnerabilidade da cidade de Arapiraca/AL, utilizou-se também, o método de Adger (2006), no qual os indicadores são classificados em três critérios: exposição, sensibilidade e capacidade de resposta do meio. Foi possível concluir que as populações socialmente vulneráveis tendem a se localizar em áreas ambientalmente vulneráveis.
