Geometric accuracy assessment of global coarse resolution satellite data sets: a study based on AVHRR GAC data at the subpixel level
Authors: Wu Xiaodan , Naegeli Kathrin , Wunderle Stefan
Published: August 2019

Abstract. AVHRR GAC (Global Area Coverage) data provide daily global coverage of the Earth, which are widely used for global environmental and climate studies. However, their geolocation accuracy has not been comprehensively evaluated due to the difficulty caused by onboard resampling and the resulting coarse resolution, which hampers their usefulness in various applications. In this study, a Correlation-based Patch Matching Method (CPMM) was proposed to characterize and quantify the AVHRR GAC geo-location accuracy at the subpixel level. This method is not limited to landmarks and not suffer from errors caused by false detection due to the effect of mixed pixels, thus enables a more robust and comprehensive geometric assessment. Data of NOAA-17, MetOp-A, and MetOp-B satellites were selected to test the geocoding accuracy. The three satellites predominately present West shifts in the across-track direction, with average values of −1.69 km, −1.9 km, −2.56 km and standard deviations of 1.32 km, 1.1 km, 2.19 km for NOAA-17, MetOp-A, and MetOp-B, respectively. The large shifts and uncertainties are partly induced by the larger satellite zenith angles (SatZ) and partly due to the terrain effect, which is related to SatZ and becomes apparent in the case of large SatZ. It is thus suggested that GAC data with SatZ less than 40° should be preferred in applications. The along-track geolocation accuracy is clearly improved compared to the across-track direction, with average shifts of −0.7 km, −0.02 km, 0.96 km and standard deviations of 1.01 km, 0.79 km, 1.70 km for NOAA-17, MetOp-A, and MetOp-B, respectively.
Evaporation from a large lowland reservoir – (dis)agreement between evaporation methods at various timescales
Authors: Jansen Femke A. , Teuling Adriaan J.
Published: August 2019

Abstract. Accurate monitoring and prediction of surface evaporation becomes more crucial for adequate water management in a changing climate. Given the distinct differences between characteristics of a land surface and a water body, evaporation from water bodies require a different parameterization in hydrological models. Here we compare six commonly used evaporation methods that are sensitive to different drivers of evaporation, brought about by a different choice of parameterization. We characterize the (dis)agreement between the methods at various temporal scales ranging from hourly to 10-yearly periods, and we evaluate how this reflects in differences in simulated water losses through evaporation of lake IJsselmeer in The Netherlands. At smaller timescales the methods correlate less (r = 0.72) than at larger timescales (r = 0.97). The disagreement at the hourly timescale results in distinct diurnal cycles of simulated evaporation for each method. Although the methods agree more at larger timescales (i.e. yearly and 10-yearly), there are still large differences in the projected evaporation trends, showing a positive trend to a more (i.e. Penman, De Bruin–Keijman, Makkink and Hargreaves) or lesser extent (i.e. Granger–Hedstrom and FLake). The resulting discrepancy between the methods in simulated water losses of the IJsselmeer region due to evaporation is ranging from −4 mm (Granger–Hedstrom) to −94 mm (Penman) between the methods. This difference emphasizes the importance and consequence of the evaporation method selection for water managers in their decision making.
Crimean Wine Market Enterprises: Challenges and Opportunities
Authors: Timirgaleeva Rena , Matyunina Marina , Shostak Marina , Makarenko Boris
Published: August 2019

The article explores the regional aspects of the Sevastopol wine business enterprises’ development by means of an analysis of the wine business market. An assessment of the potential of the viticulture and winemaking agro-industrial subcomplex was made taking into account the new economic conditions: the integration of the region into the Russian economic space, and the need to implement the import substitution policy. The production indicators of the five largest enterprises in this field were analyzed. The presence of a large variety of services and products in the field of winemaking and the potential resources of viticulture were distinguished. The study showed that viticulture and winemaking, the production and sale of wine materials have always been among the most attractive branches of the agro-industrial complex of the Crimea, where the largest of the leading regions of viticulture is the federal city of Sevastopol. The conducted assessment made it possible to identify the high potential of the regional industry that can be effectively implemented, provided that the wine cluster and terroir winemaking are formed and implemented.
Seismic analysis of in-plane loaded walls in unreinforced masonry buildings with flexible diaphragms
Authors: Nakamura Yasuto , Derakhshan Hossein , Ingham Jason M. , Griffith Michael C.
Published: August 2019

It is well recognised that the dynamic response of unreinforced masonry buildings with flexible timber diaphragms typically contains multiple dominant modes associated with the excitations of the diaphragms and the in-plane walls. Existing linear analysis methods for this type of structure commonly account for the multi-mode behaviour by assuming the independent vibrations of the in-plane loaded walls (in-plane walls) and the diaphragms. Specifically, the in-plane walls are considered to be rigid and the unmodified ground motion is assumed to be transmitted up the walls to the diaphragm ends. While this assumption may be appropriate for many low-rise unreinforced masonry buildings, neglecting the dynamic interaction between the diaphragms and the in-plane walls can lead to unreliable predictions of seismic demands. An alternative analysis approach is proposed in this paper, based on the mode properties of a system in which (1) the mass ratios between the diaphragms and the in-plane wall are the same at all levels, and (2) the periods of the diaphragms are the same at all levels. It is proposed that under these conditions, two modes are typically sufficient to obtain the peak seismic demands of the in-plane walls in elastically responding low-rise regular buildings. The applicability of the two-mode analysis approach is assessed for more general diaphragm configurations by sensitivity analysis, and the limitations are identified. The two-mode approach is then used to derive a response modification factor, which may be used in conjunction with a linear static procedure in the seismic assessment of buildings with flexible diaphragms.
Investigating Chinese EFL College Students’ Writing Through the Web-Automatic Writing Evaluation Program
Authors: Song Zongwei
Published: August 2019

WWE-pigai is a kind of upgraded automated writing evaluation (AWE) system and there are 444,877,400 essays submitted and corrected on this platform. Some previous research on AWE system indicates that students do not tend to utilize AWE feedback to revise essays and improve writing abilities. The major objective of this study is to investigate Chinese EFL college students’ writing through the comparison of WWE-pigai and traditional writing method. The study lasts two terms and 120 Chinese colleges students participate in the research. The findings reveal that WWE-pigai can motivate EFL students to revise and resubmit their essays more than ten times, improve the scores, increase students’ grammar accuracy and vocabulary richness. The surface-level spelling errors (including punctuation mark misuse) are the most common for freshmen. WWE-pigai is not very effective to correct certain grammatical errors besides spelling and conjugation errors. For certain grammatical errors that the students cannot correct by themselves, the assistance of EFL teachers is necessary. We argue that the results reached through this study can offer useful implications for the usage of EFL writing strategies.
The Effects of Previous Grazing on the Subsequent Nutrient Supply of Ungulates Grazing Late-summer Mixed-Conifer Rangelands
Authors: Damiran Daalkhaijav , DelCurto Timothy , Findholt Scott L. , Johnson Bruce K. , Vavra Martin
Published: August 2019

Ecological, societal, and political discussions abound regarding intra- and inter-specific competition for nutrients among wild and domestic ungulates grazing shared forested rangelands in summer as cascading effects of prior grazing drive subsequent grazing patterns and nutrient intake. Our objective was to determine diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus; deer), and elk (Cervus elaphus nelsoni) in late-summer in response to early-summer forage utilization by cattle and elk in two consecutive years. Four 2.25 ha enclosures were constructed in previously logged mixed-conifer rangelands dominated by grand fir (Abies grandis [Douglas] Forbes.), and within each enclosure, a 0.75 ha paddock was either: 1) ungrazed, 2) grazed by cattle, or 3) grazed by elk in mid-June and mid-July at a moderate utilization level (31.9 ± 2.7%). After grazing treatments, each paddock was subdivided into three 0.25 ha sub-paddocks and sixteen 20-minute foraging bouts were conducted in each sub-paddock using elk, deer, and cattle (n = 4). Within an animal species CP in diets did not differ (p > 0.05) between ungrazed paddocks and grazed paddocks; however, diet CP and IVDMD of each species was higher (p < 0.05) on cattle grazed paddocks compared to elk grazed. Regardless of treatment, cattle diets contained lower CP, IVDMD (p < 0.05) than did deer or elk diets, and relative to elk, deer consistently selected diets which contained higher CP (p < 0.05). In response to grazing, intake rate of DM, CP, ME did not change (p > 0.05) for any of the ungulates. The study revealed that early-summer grazing by cattle or elk at a moderate utilization level has minimal effect on the subsequent nutrient intake rate of cattle, deer, and elk foraging in mixed-conifer forests.

Practical aspects of heat conduction simulation in household heating optimization tasks
Authors: Duda Jan Tadeusz
Published: August 2019

Mathematical model selection for simulation heat conduction processes in household heating optimization task is considered. The essence of the matter is that the heat transfer dynamics properties are very diversified, so simulation procedure formulae and parameters should be properly selected to avoid excessive modeling errors with reasonable calculation time being held. The typical state-space model and analytical formulae for step response of the heat conduction across a homogeneous wall are presented and compared in terms of modeling errors. Formal and numerical problems of heat losses simulation are discussed. Semi-analytical step-response formulae for multilayer walls are derived and their accuracy is compared with effects of simulation based on the state-space model. Some recommendations for time and space discetization parameters are given.
How the axial flux of an induction motor can be used?
Authors: Petryna Janusz
Published: August 2019

The article contains the results of research within the project to apply unipolar (axial) flux to obtain diagnostic signals carrying the information of: electrical asymmetries of machinery (inter-turn stator short-circuits, cage damages); rotational speed of the rotor and load torque. Inter-turn stator short-circuits can be detected both at starting process time (when they appear most often), as well as in steady states. Detection of rotor cage defects in steady states has a character of a comparative study, and over time, as the defects develop. For standard drives that are powered from the network and work in open systems, by measuring the voltage following a unipolar flux, it is possible to make measurement and recording of motor speed, which usually is almost never provided under industrial conditions. The study shows that a simple in its construction, cheap coil can be a very useful diagnostic tool. The measurements were carried out at the laboratory and motor workplace in the power plant, while in the test station, during the loading, characteristics illustrating the dependence of the torque on the axial flux and on the rotational speed were obtained. A way of using a single measurement to estimate the torque has been proposed. The method is relatively simple to implement and allows for a fully non-invasive determination of the load torque.

Published: August 2019

Several times the French Senate has proposed introduction of split payment in France, however, each time the French National Assembly rejected such a proposal. This contrast between two houses of the French parliament shows very well how controversial split payment is. Yet, it is in force in Poland since the 1st of July, 2018. Since one year from its introduction has passed it is a good moment to analyse the first Polish experiences with this mechanism with special regard to experiences of other states which decided to introduce split payment. Such an analysis should lead to conclusion that the Polish split payment mechanism is not finished yet – so far it was only its voluntary supplement that had been introduced. Such a voluntary mechanism is unlikely to be popular and so it is so far. The proper, i.e. obligatory, split payment is to come into force on the 1st of September, 2019. The projected law does not seem to vary much from solutions adopted in other countries. Experiences of all states prove how difficult it is to draft a high-quality and efficient law on split payment. Moreover, split payment is meant to tackle the problem of the so-called missing trader frauds – analysis shows that it does not preclude such dealings. Therefore, it is not the final solution for problems of VAT.

Published: August 2019

Karakteristik dinamika seas dan swell di sepanjang perairan Laut China Selatan-Teluk Jakarta pada waktu terjadi Badai Hagibis (18"“27 November 2007) dikaji dengan menggunakan metode pemodelan spektrum gelombang untuk mengetahui kontribusi gelombang yang dibangkitkan angin (gelombang angin) terhadap kejadian rob tanggal 25 November 2007 di pantai utara Jakarta. Pada penelitian ini, dilakukan pula uji coba simulasi model spektrum gelombang yang mengacu pada kedalaman tetap (batimetri) dan pada kedalaman total (jumlah batimetri dan pasang surut astronomis) untuk mengetahui pengaruh pasang surut astronomis terhadap hasil simulasi model gelombang yang dibangkitkan angin. Hasil simulasi menunjukkan bahwa gelombang angin di Teluk Jakarta pada tanggal 25 November 2007 didominasi oleh swell dengan tinggi gelombang ~11 cm yang diduga berasal dari Laut China Selatan sebagai daerah pembangkitan badai.Characteristics of seas and swell dynamics along South China Sea-Jakarta Bay waters during Cyclone Hagibis passage (18"“27 November 2007) have been studied using a spectral wave model to understand the magnitude of wind wave contribution to flooding event on November 25, 2007 along the northern coast of Jakarta. In this study, the model simulation was conducted using two kinds of water depth input, namely fixed water depth and timevarying water depths resulting from tides in order to obtain a better understanding of tidal influence on wind wave simulations. The simulated result shows that wind wave in the Jakarta Bay was dominated by swell with significant wave height of ~11 cm. It was expected that the swell propagated from the South China Sea as a storm generating area.
Totalistic Programs for Youth
Authors: Chatfield Mark M
Published: August 2019

Recent annual estimates suggest that in the United States, approximately 57,000 young people are placed by their parents into some type of residential treatment program. Parent – pay programs are exempt from federal safety standards and some states provide little or no regulatory oversight. Federal investigations revealed a nationwide pattern of institutional abuse across multiple facilities, and some professionals have noted ‘cruel and dangerous uses of thought reform techniques’ within such programs (U.S. House of Representatives 2007, 76). This article summarizes qualitative research based on interviews with 30 adults who lived for an average of 20 months within a ‘highly totalistic’ youth program. The concept of totalistic treatment was operationalized and measured with seven key identifiers found in the literature. Twenty – five different programs of four general types were represented: therapeutic boarding schools, residential treatment centers, wilderness/outdoor programs, and intensive outpatient programs. To organize qualitative findings, three themes explaining the experiences, immediate effects, and long – term impacts of treatment help to reveal implicit meanings woven throughout the interviews. By understanding a wider range of experiences associated with totalistic programs, efforts to improve quality of care and strategies to prevent harm may be improved. Harm prevention efforts would benefit from the analytical perspectives found in theories of coercive persuasion and thought reform.

Two new species of groundwater amphipods of the genus Niphargus Schiödte, 1849 from northwestern Iran
Authors: Mamaghani-Shishvan Mahmoud , Esmaeili-Rineh Somayeh
Published: August 2019

This study was conducted to describe and illustrate two new species of groundwater amphipods from the northern parts of the Zagros Mountains in West Azerbaijan Province, Iran. Mitochondrial (COI) and nuclear (28S rDNA) fragments as well as several morphological traits were used to characterize Niphargus urmiensis sp. nov. and Niphargus fiseri sp. nov. The phylogenetic analyses showed that the nucleotide differences between the recently described species and their close allies are attributed to their distinctiveness. The molecular analysis also introduced that the new species are placed within the clade comprising Iranian species as a sister taxon. The genetic distances between N. urmiensis sp. nov. and N. fiseri sp. nov. are 7.6% and 1.6%, respectively based on the COI and 28S rDNA gene fragments.

Published: August 2019

O artigo trata das implicações teórico-críticas da renovação dos estudos de retórica, com atenção para os estudos de João Hansen, Alcir Pécora, Adma Muhana, Hélio Alves e Belmiro Pereira. Numa primeira parte, discutimos esquematicamente a limitação das categorias literárias para abordagem de textos anteriores ao conceito “teórico” de literatura; numa segunda, fazemos observações para um modelo de estudo que atenda ao imperativo cognitivo da discriminação de períodos e que não recaia naquelas limitações epistêmicas. Trata-se de pensar a possibilidade de periodizar a partir dos estudos de retórica, tomando por horizonte a elaboração de uma ideia de “espaço ético-retórico” como ferramenta periodológica.

Authors: Martín López Raquel
Published: August 2019

La preocupación por la sostenibilidad ha adquirido importancia en los últimos años en la industria de la moda, tras la tragedia del derrumbe del Rana Plaza en Bangladesh en 2013, donde se puso de manifiesto las posibles deficiencias en las memorias de sostenibilidad de los grandes grupos del sector. El objetivo principal de la investigación es verificar si las principales marcas de fast fashion españolas e italianas, incorporan criterios de sostenibilidad corporativa, tanto en el punto de venta físico, como en el online. La investigación ha sido llevada a cabo mediante dos técnicas cualitativas. En primer lugar, el análisis de contenido de la tienda online o web corporativa en Italia de Zara, Mango, Calzedonia y OVS. En segundo lugar, un estudio descriptivo del punto de venta físico en la capital italiana de las marcas seleccionadas. Los resultados revelan que las marcas Zara, Mango y OVS realizan una mayor inclusión de su sostenibilidad corporativa en sus canales de comunicación: en la web corporativa en el caso de Zara y OVS, y en la tienda online en el caso de Mango. El merchandising no es explotado por las marcas analizadas.
La sociologie de l’environnement au défi de l’intendance écologique. Comment repenser l’action individuelle dans la gestion collective de l’environnement?
Authors: Allouche Aurélien
Published: August 2019

Les paradigmes d’intendance écologique se développent aussi bien dans les sciences de l’environnement que dans la gestion des aires protégées. Le concept d’intendance, encore récent en France, ne trouve aucune correspondance dans les théories sociologiques de l’action. Cette situation soulève de nombreuses difficultés pour la recherche interdisciplinaire. Cet article examine différentes théories de l’intendance sous l’angle des théories de l’action qu’elles supposent, afin de contribuer à une conception sociologique de l’intendance. Trois études de cas sont utilisées à cette fin.
L’Église catholique et l’anthropocène : 50 ans de positionnement doctrinal
Authors: Sajaloli Bertrand , Grésillon Étienne
Published: August 2019

L’Église catholique, accusée par Lynn White (1967) d’être impliquée dans les crises environnementales planétaires, a peu à peu construit une réponse philosophique et spirituelle en faveur du respect de la création en remobilisant les tensions anciennes entre les deux principales traditions chrétiennes de la nature, l’anthropocentrisme et le théocentrisme. Avec l’encyclique papale de François Laudato si (2015), elle prône aujourd’hui sobriété, réduction de la consommation en même temps qu’elle engage les croyants du monde entier à adopter des comportements écologiquement plus vertueux. C’est cette trajectoire doctrinale qui est analysée : aboutissement de 50 années de pensée religieuse de l’environnement, l’écologie chrétienne est confrontée à l’histoire récente de l’écologie et notamment à celle de l’écologie politique. Appartenant à la cité, l’Église a construit son discours en trois grandes étapes en fonction des courants de pensée (dont l’anthropocène) qui traverse la société civile, des catastrophes environnementales majeures (Tchernobyl, changement climatique) et des grandes scènes politiques comme les sommets de la Terre de Rio 1992 et 2012.
Les délaissés urbains : supports de nouvelles pratiques et représentations de la nature spontanée? Comparaison des représentations des gestionnaires et des habitants
Authors: Brun Marion , Di Pietro Francesca , Martouzet Denis
Published: August 2019

Les délaissés urbains sont des espaces sans fonction officielle et en rupture avec le tissu urbain environnant. Espaces transitoires présentant souvent une végétation spontanée, les délaissés constituent un habitat pour de nombreuses espèces végétales et leur intérêt pour la biodiversité urbaine est maintenant reconnu. Ils représentent aussi des lieux privilégiés pour augmenter le contact des habitants avec la nature et répondre à la croissante demande sociale de nature en ville. Par ailleurs, l’intérêt des délaissés urbains comme objet d’aménagement est largement documenté en urbanisme; toutefois les représentations des urbanistes et gestionnaires sur les délaissés ont été peu étudiées. L’objectif de ce travail est d’explorer les représentations comparées des délaissés urbains par les gestionnaires (propriétaires et non propriétaires de délaissés) et les habitants riverains de ces espaces. Une méthodologie spécifique d’enquête pour chaque type d’acteur a été mise en place sur nos sites d’étude, les agglomérations de Tours et Blois. Une partie des habitants riverains adoptent sur les délaissés des pratiques temporaires, qui sont souvent tolérées par les propriétaires et n’affectent pas les usages définitifs du terrain, qui sont principalement la construction et la commercialisation des délaissés, lorsque les terrains sont constructibles. Malgré des points de vue contrastés entre gestionnaires et habitants, les délaissés sont majoritairement représentés comme des espaces non entretenus, abandonnés, végétalisés et temporaires. Toutefois pour certains habitants ce devenir incertain revêt un aspect positif, car il est associé à une idée de « liberté » qui confirme la demande sociale d’espaces de respiration dans la ville de la part de certains habitants. Deux pistes pour une meilleure intégration des délaissés dans la ville sont formulées en conclusion, qui permettraient de valoriser pour les habitants, mais aussi pour les gestionnaires, ces espaces urbains en attente.
Aprendizaje virtual, trabajo en red y salarios: ¿nueva empleabilidad, nuevas paradojas?
Authors: Torrent-Sellens Joan
Published: August 2019

Este artículo analiza el papel que tiene la formación virtual en el logro de las nuevas condiciones de empleabilidad que demanda la irrupción del trabajo en red y de la economía y la sociedad del conocimiento. Bajo el marco analítico del cambio tecnológico digital sesgador de habilidades y a partir de los resultados de tres investigaciones empíricas, el análisis realizado ha obtenido cuatro conclusiones principales. Primera, la formación virtual para la empleabilidad no dispone todavía de bastante impulso para romper la divisoria de la formación, es decir, que en ella se forman los trabajadores más formados y con más competencias digitales. Segunda, la formación virtual se revela como un instrumento de calidad para la mejora de la empleabilidad de los trabajadores, en especial en sus dimensiones de competencias adquiridas y de satisfacción con el diseño pedagógico, pero menos con la aplicabilidad de la formación. Tercera, la gran mayoría de empresas, las que no presentan cambio estructural, determina un problema de sobreeducación relativa, es decir, que no se cumple la asociación entre un mayor nivel formativo y un mayor salario. Y, cuarta, a pesar de que la formación virtual ha realizado avances notables como instrumento de empleabilidad, en la actualidad presenta dos importantes debilidades: 1) la necesidad de alcanzar a colectivos más amplios de trabajadores; y 2) la necesidad de potenciar la formación virtual como una palanca de cambio estructural (complementariedades con el cambio organizativo y los usos TIC) en las empresas.

In its editorial page, the journal introduces the dossier of the second Oikonomics issue. As social media are a current topic, the dossier includes five contributions by experts suggesting different approaches to how social media relate with economics and business, in order to provide more detailed information on their use and opportunities. The idea is forwarded from different perspectives (information management, marketing, business organisations, financial markets, social change…) in an environment where opportunities and challenges posed by online social media have a significant impact on the global economy. Information and Communication Technologies (ICT) stimulate innovative dynamism and have become one of the main foundations of the radical change experienced by the economy and social structures in the last decade as they are becoming a massively used resource affecting all economic and social stakeholders.

We used a logic distance to investigate intra and inter-individual variation in the phrase combinatorics of a singing primate, the indri, which inhabits the montane rain forests of Madagascar. Indris combine long notes, short single notes, and phrases consisting of two, three, four, or five units with slightly descending frequency. We calculated the similarity across different individual songs using the Levenshtein distance. We then analyzed the degree of similarity within and between individuals and found that: i) the phrase structure of songs varied between reproductive males and females; ii) male contributions to the song are overall more similar to those of other males; iii) male contributions are more stereotyped than females' ones. The picture emerging from phrase combinatorics in the indris is in agreement with previous findings of rhythmic features and repertoire size, which also suggested that female songs are potentially more distinctive than those of males.

Purpose

Radioactive iodine (RAI) is widely used for adjuvant therapy after thyroidectomy, while its value for thyroid cancer has been controversial recently. The primary objectives of this study were to clarify the influence of Radioactive iodine (RAI) on the survival in rare oxyphilic subtype of thyroid cancer (Hürthle cell carcinoma, HCC).

Methods

Patients diagnosed with oxyphilic thyroid carcinoma from 2004 to 2015 were extracted from the Surveillance, Epidemiology, and End Results Program database. The Kaplan-Meier method was used to compare overall survival (OS) and cancer-specific survival (CSS) among patients who had adjuvant RAI use or not. Univariate and multivariate Cox proportional hazard models were performed for survival analysis, and subsequently visualized by nomogram.

Results

In all, 2,799 patients were identified, of which 1529 patients had adjuvant RAI use while 1,270 patients had not. Based on multivariate Cox analysis, the RAI therapy confers an improved OS for HCC patients (HR = 0.57, 95% CI [0.44–0.72],P < 0.001), whereas it has no significant benefit in the survival analysis regarding CSS (HR = 0.79, 95% CI [[0.47–1.34],P = 0.382). In a subgroup analysis, the same survival benefit of RAI treatment on OS, but not CSS was observed among patients stratified by AJCC stage and tumor extension. Nevertheless, patients with regional lymph node metastasis benefited from RAI therapy both in OS and CSS (P < 0.001, respectively). Furthermore, nomograms used for predicting long term survival of HCC patients exhibited a better prediction power for OS compared with traditional tumor, nodal and metastatic (TNM) stage made by American Joint Committee on Cancer (AJCC) (C-index = 0.833 of the nomogram model vs. 0.696 of the AJCC system).

Conclusions

This study suggests that RAI therapy is significantly associated with improved OS in patients with Hürthle cell carcinoma. However, there was no association between treatment with radioiodine and CSS, possibly due to small number of deaths that were related to HCC.

Published: August 2019

Background: Gout causes attacks of pain and swelling in one or more joints and control of serum uric acid level has been used as one of the therapeutic methods for gout. Inhibition method of xanthine oxidase (XO) activity which can oxidize hypoxanthine to uric acid has been commonly used to decrease serum uric acid level. On the other hand, Elephantopus scaber Linn leaf has been used for the treatment of rheumatoid arthritis as folk medicine by some people in Indonesia.

Aims: This study was to determine the hypouricemic effect of ethanol extract of Elephantopus scaber leaf by in vivo study in caffeine (PO)-induced hyperuricemic male rats.

Methodology: The E. scaber leaf was obtained from Research Institute for Spices and Medicinal Plants, Bagor, Indonesia. Preparation of E. scaber leaf extract was done by cold maceration extraction technique using ethanol 70%. Male rats (Sprague-Dawley) were induced by using caffeine with dose 27 mg/200 g b.w until the levels in the blood of male rats become hyperuricemic. Equipment (Easy Touch) was used by detecting the level of uric acid in a rat blood. Equipment (Easy Touch) was used by detecting the level of uric acid in a rat blood. Rats were divided into 6 groups, as a positive control was used allopurinol 36 mg/200 g b.w, test preparation were used 3 doses, i.e, 175 mg/200 g b.w,  350 mg/200 g b.w and 700 mg/200 b.w which suspended in Na-CMC 0.5%.

Results: The results from a decrease in blood uric acid levels in rats, on the 15th days showed that a dose of 350 mg / 200 g b.w gave decrease in the highest percentage ie 43%. Statistical analysis on the 15th day showed that all of the test preparation groups of E. scaber had effects decrease uric acid in blood serum of rats and significantly different from negative controls (p ≤ 0.05). The dose of 350 mg/200 g b.w of E. scaber had the same effect with a dose of 36 mg/200 g b.w allopurinol in reducing uric acid in experimental rats.

Conclusions: E. scaber is a plant that is quite potential to be used in the treatment of gout.
A Vector Autoregression Analysis of the Efficacy of External Reserves Management on Exchange Rate Stability: Evidence from Nigeria
Authors: Kelikume Ikechukwu , Nwani Stanley Emife
Published: August 2019

This paper investigates the dynamic relationship between exchange rate variations and international reserves in Nigeria. The study aimed at ascertaining whether a lead-lag relationship exists between both phenomena using monthly time series data on the bureau de change exchange rate and international reserves extracted from the statistical bulletin of the Central Bank covering 108 observations between January 2010 and December 2018. The econometric techniques utilized included the Granger causality based on the vector error correction mechanism and the AR inverse root test for stability and reliability. The empirical result indicates the absence of causality between exchange rate volatility and international reserves fluctuations for Nigeria. Based on our empirical result, the study vehemently concluded that monetary authorities do not have to depend on external reserves management as an efficient strategy to stabilizing the value of the Nigerian currency. Thus, external reserves accumulation could be a face lifting parameter for credit ratings and attraction of needed capital to stimulate the much desired economic growth in Nigeria.

Published: August 2019

Background: Iranian traditional medicine is the oldest form of medical structure and is, in fact, an inseparable part of the life of various Iranian societies. On the other hand, gastrointestinal and liver diseases are one of the most common causes of morbidity in the world, including in Iran. Such that 10% of diseases are allocated to them and their diseases are spreading increasingly.

Objective: Considering the mentioned issues and the high prevalence of gastrointestinal symptoms, the aim of this study is to investigate the compliance of the symptoms of gastrointestinal diseases in classical medicine with Iranian traditional medicine from the viewpoint of Iranian traditional medicine experts.

Methods: This is a hybrid qualitative study which was conducted in three phases, including 1- theoretical, 2- field and 3- combinational phases. In the theoretical phase, two types of medical textbooks i.e. Iranian traditional and classic medicine textbooks. In the field stage, 13 academic Iranian traditional medicine experts with at least 5 years of work experiences in Iranian traditional medicine were interviewed. Then, in the combinational phase, the results of two early phases have been summarized using descriptive statistics.

Results: The results of the study show that 12 of the 40 symptoms in this study had a compliance of 100%. These 12 symptoms are Increase of Salivation, Pica, Borborygmi, Hiccups, Abdominal distention, Melena, Anal Fissure, Anal Stenosis, Cryptitis, Anal pruritus, Halitosis, Rectal pain; also, the results showed that 10 of the 40 symptoms in this study had over 70% compliance. These 10 symptoms are as Dysphagia, Belching, Regurgitation, Hematemesis, Flatulence, Increased Bowel sound, Abdominal pain, Diarrhea, Jaundice and Anal prolapse. Also, the percentage of compliance with the other 18 symptoms was less than 70%.

Conclusion: Considering the results of this study and the capabilities of Iranian medicine in relation to symptoms of gastrointestinal diseases with classical medicine, it is possible to design appropriate patterns to expose it. Also, an integrated approach to clinical research is recommended to improve the efficacy and safety of gastrointestinal treatments.
