El platanal o la nación. Representaciones sociales y prácticas en torno al plátano en la Colombia del siglo XIX
Authors: Robledo Escobar Natalia , Gutiérrez Escobar Laura , De la Hoz Nelsa
Published: February 2021

A partir de la reflexión teórica sobre representaciones sociales, del análisis de textos de las élites y viajeros extranjeros y de las prácticas de producción y consumo del plátano (Musa paradisiaca), nos preguntamos cómo fue representado este producto entre 1780 y 1900 en las tierras calientes del bajo y medio río Magdalena. Argumentamos que el plátano fue un marcador de la frontera entre el “nosotros” (blanco, urbano, de las élites) y los “otros” (racialmente diversos, rurales, analfabetas). Al ser representado como un “no-cultivo” tropical y cómplice del ocio de los ribereños, especialmente zambos, apareció como atávico, obstáculo para la civilización y forma de resistencia.
Los procesos de profesionalización en la policía de la provincia de Buenos Aires en épocas de cambio (fines del siglo XIX y principios del siglo XX)
Authors: Berardi Pedro
Published: February 2021

El artículo examina las múltiples formas desplegadas por el cuerpo policial de la provincia de Buenos Aires con el propósito de profesionalizar a sus agentes en el cambio del siglo XIX al XX; periodo y espacio que han sido poco atendidos por la historiografía. Se aborda el perfil de los hombres que se insertaron en la policía —principalmente en las funciones de seguridad— y los diferentes mecanismos de reclutamiento. Asimismo, se estudian distintas instancias de capacitación y aprendizaje, como la recepción de modelos extranjeros de organización, que tuvieron un impacto significativo en la construcción de la policía como una institución moderna.

Published: February 2021

Según el informe de la Agencia Europea para la Seguridad y Salud en el Trabajo, el dolor de hombro (DH) es uno de los problemas de salud laboral más comunes de Europa. Esta dolencia es especialmente frecuente en los trabajadores de limpieza viaria y recogida de residuos. El proyecto Prevención y Readaptación Física Laboral (PRE-REFILAB) es una intervención novedosa de prevención y readaptación física en el ámbito laboral. El objetivo del presente estudio fue determinar el riesgo del DH de los trabajadores de limpieza viaria y recogida de residuos de una empresa de servicios urbanos del municipio de Murcia. Un total de 18 trabajadores con edades comprendidas entre 38 y 62 años (52,5±7,1 años) participaron en este estudio. Los trabajadores se caracterizaban por presentar alguna incapacidad temporal laboral por DH en los últimos 12 meses. La composición corporal, la disposición sagital del raquis, el rango de movimiento (ROM) y la fuerza isométrica del hombro fueron evaluadas en este estudio. De acuerdo con los valores de referencia pronóstico establecidos para la población general sana, un análisis descriptivo individual de las diferentes variables evaluadas fue realizado para identificar a los participantes con alto riesgo de DH. El análisis estadístico de dos muestras pareadas mostró asimetría en el ROM de rotación interna de hombro (p = 0,032). Los trabajadores de la empresa de servicios urbanos (≥39% del total) muestran peores valores en la mayoría de los factores de riesgo de dolor de hombro evaluados (composición corporal, curvatura dorsal, ROM de hombro-flexión, aducción y rotación interna- y fuerza de rotación interna) que los valores de referencia de la población general.
Communities of Darkness? Users and Uses of Anti-System Alternative Media between Audience and Community
Authors: Schwarzenegger Christian
Published: February 2021

The hopes regarding the positive impact of the Internet and digital participation in civic society have faded in recent years. The digital realm is now increasingly discussed regarding its role in putting democracy in jeopardy and polarizing public debate by propagating extremist views and falsehoods. Likewise, the perception of so-called alternative media as beneficial carriers of counter-public spheres and as important complements to mainstream positions in social debate has flipped. Alternative media are now often associated with the “Wicked web” of disinformation, political populism, or even radicalization. Following Quandt’s (2018) notion of ‘dark participation’ and Phillips and Milner’s (2017) description of the Internet as ambivalent, this article asks, whether the same holds true for the users of alternative media: a segment of the audience traditionally discussed in terms of community, engagement, participation, and strong ideological identification with progressive political causes. Do users of ‘dark’ alternative media bond with their media in similar ways to constitute communities of darkness? Based on interviews with 35 users of alternative media from a left-leaning, right-wing, Russian-tied and/or conspiracy spectrum users, uses of alternative media are pictured as grey rather than black or white. The findings illuminate the ambivalences within alternative media users as audiences and communities. Ambivalences are found regarding the use of alternative sources as audience or community members, regarding a shared attitude of criticality and anti-systemness, which connects trans-medially and trans-ideologically, as well as the experienced comfort of community, which can become a main motivation for use.

Published: February 2021

Political communication increasingly takes on visual forms. Yet, despite their ubiquity in everyday communication and digital campaigning, the use of these visuals remains critically understudied. In this article, we investigate the formats and modes of visual content deployed by Twitter users over a two-week period leading up to the 2019 EU Parliamentary elections and across two publics: those discussing the election at large and those discussing the more contentious issue of EU membership. Conducting a multilingual, cross-comparative content and thematic analysis of a sample of 1,097 images, we find that: (1) Visuals originating from traditional political actors prevailed among both Twitter discourses; (2) users shared substantial amounts of anti-EU, populist and, to a lesser extent, extremist images, though this content remained largely disjointed from the mainstream public debate; and (3) political humor emerged as a vector for anti-establishment and Eurosceptic themes, especially in discussions critical of the European project. We discuss the implications of our findings for the study of visual political communication and social media manipulation.
Constructive Aggression? Multiple Roles of Aggressive Content in Political Discourse on Russian YouTube
Authors: Bodrunova Svetlana S. , Litvinenko Anna , Blekanov Ivan , Nepiyushchikh Dmitry
Published: February 2021

Today, aggressive verbal behavior is generally perceived as a threat to integrity and democratic quality of public discussions, including those online. However, we argue that, in more restrictive political regimes, communicative aggression may play constructive roles in both discussion dynamics and empowerment of political groups. This might be especially true for restrictive political and legal environments like Russia, where obscene speech is prohibited by law in registered media and the political environment does not give much space for voicing discontent. Taking Russian YouTube as an example, we explore the roles of two under-researched types of communicative aggression—obscene speech and politically motivated hate speech—within the publics of video commenters. For that, we use the case of the Moscow protests of 2019 against non-admission of independent and oppositional candidates to run for the Moscow city parliament. The sample of over 77,000 comments for 13 videos of more than 100,000 views has undergone pre-processing and vocabulary-based detection of aggression. To assess the impact of hate speech upon the dynamics of the discussions, we have used Granger tests and assessment of discussion histograms; we have also assessed the selected groups of posts in an exploratory manner. Our findings demonstrate that communicative aggression helps to express immediate support and solidarity. It also contextualizes the criticism towards both the authorities and regime challengers, as well as demarcates the counter-public.
Sequential Feature Maps with LSTM Recurrent Neural Networks for Robust Tumor Classification
Authors: BATUR ŞAHİN Canan , DİRİ Banu
Published: January 2021

In the field of biomedicine, applications of
the identification of biomarkers require a robust gene selection mechanism. For
identifying the characteristic marker of an observed event, the selection of
attributes becomes important. The robustness of gene selection methods affects
detecting biologically meaningful genes in tumor diagnosis. For mapping,
sequential features Long-short-term memory (LSTM) was used with Artificial
Immune Recognition Systems (AIRS) to remember gene sequences and effectively
recall of learned sequential patterns. An attempt was made to improve AIRS with
LSTM which is a type of RNNs to produce discriminative gene subsets for finding
biologically meaningful genes in tumor diagnosis. The algorithms were evaluated
using six common cancer microarray datasets. By converging to the intrinsic
information of the microarray datasets, specific groups like functions of the
co-regulated groups were observed. The results showed that the LSTM based AIRS
model can successfully identify biologically significant genes from the
microarray datasets. Also the predictive genes for biological sequences
areimportant in gene expression microarrays.This study confirms that different
genes can be found in the same pathways. It was also found that the gene
subsets selected by the algorithms were involved in important biological
pathways.In this work we try an LSTM on our learning problem. We suspected that
recurrent neural networks would be a good architecture for making
predictions.The results show that the optimal gene subsets were based on the
suggested framework, so they should have rich biomedical interpretability.
A Comparative Study of PM Synchronous Generator for Micro Hydropower Plants
Authors: DALCALI Adem
Published: January 2021

Developing technology and growing population are increasing the need of countries for energy every passing day. Renewable energy resources, which are an environmentally friendly and local solution alternative to fossil fuels, are seen to be a significant source of supply in this matter. Among renewable energy resources, hydroelectric energy is in an advantageous position with its reliable potential and sustainable production. With the purpose of utilizing small flowing waters such as rivers and streams and solving problems of access to interconnected grids in rural areas, micro-type hydroelectric power plants have a significant potential for countries. This study carried out the design and performance analyses of permanent magnet synchronous generators with different numbers of poles for micro hydroelectric power plants. The generators’ flux density values and total voltage harmonic distortions were examined. Additionally, the cogging torque magnitudes have been analyzed. The generators were loaded with nominal loads, and the time-dependent waveforms of phase voltages were obtained. By subjecting the obtained voltages to Fourier analysis, their harmonic spectrum was created. Finally, by considering the amount of active material used for the designs, their costs were compared.
A Graphical Tool For Assessing The Suitabilty Of A Count Regression Model
Authors: Wilson Paul , Einbeck Jochen
Published: February 2021

Whilst many numeric methods, such as AIC and deviance, exist for assessing or comparing model fit, diagrammatic methods are few. We present here a diagnostic plot, which we refer to as a `Quantile Band plot', that may be used to visually assess the suitability of a given count data model. In the case of diagnosed model inadequacy, the plot has the unique feature of conveying precise information on the character of the violation, hence pointing the data analyst towards a potentially better model choice.
Likelihood Ratio Test and Non-parametric Test for Load Sharing
Authors: Sutar Santosh Shashikant
Published: February 2021

In present article, we propose a likelihood ratio test and a non-parametric test for testing the load sharing effect observed in the two component parallel load sharing system. We have modeled the load sharing phenomenon observed in such system by the exponentiated conditional distribution function based load sharing model proposed by Sutar and Naik-Nimbalkar (2016). We have taken component baseline distribution as Weibull distribution and linear failure rate distribution. The simulation study to see the performance of proposed test procedures is reported. We analyze two data sets for illustrative purpose.
Dimethylchlorosilanaerosyl Impregnated With A Acetone Or Ethanol - A Multifunctional Sorbent For The Separation Of Microquantities Of Al (III), Ga (III), In (III)
Authors: Chebotarev A.N. , Rakhlytskaya E.M. , Shcherbakova T.M. , Snigur D.V.
Published: February 2021

A multifunctional sorbent for the separation of microquantities of elements-analogues of the aluminum subgroup was obtained by impregnation of the dimethylchlorosilanaerosyl (DMCSA) surface with a polar organic solvent (POS). The surface identification of the organized DMCSA - POS system was performed via diffuse reflection spectroscopy. The results of the study of Al (III), Ga (III), In (III) sorption using an organized system DMCSA - POS depending on the medium acidity and the nature of POS (ethanol or acetone) showed that the quantitative and selective removal of the studied elements corresponds to the formation of the neutral hydroxoforms and is due to kinetic and thermodynamic differences in the ability of Al (III), Ga (III), In (III) to hydrolysis. A participation in adsorption-extraction processes hydrophobically attached to the methyl groups of DMCSA layer POS also takes place. A method of stepwise separation of Al (III), Ga (III), In (III) from their three- and multicomponent mixtures is proposed. At the same initial concentrations of elements, the values of the separation coefficients of pairs Ga (III) - In (III) ≈ 1450 and In (III) - Al (III) ≈ 450 were calculated.

Authors: Antonyuk V.O. , Panchak L.V. , Tsivinska M.V. , Stoika R.S.
Published: February 2021

The biologically active aldehydes in extracts of fungi of the genus Lactarius were identified. It’s established that these substances are unstable, they are found in fresh and frozen fungi, but are absent in dried mushrooms and interact with 1,4-phenylenediamine to form a colored compound. Methylene chloride is the best extragent for these substances. TLC on silufol plates showed that there were several substances in Lactarius pergamenus fruiting bodies and they had varying degrees of stability. For selection of these substances, methylene chloride extract was separated on a column of silica gel. Fraction, which gave the most expressive reaction with 1,4-phenylenediamine on thin-layer chromatograms were analyzed by GC-MS both in the absence and in the presence of 1,4-phenylenediamine. As a result, it was found that 1,4-phenylenediamine or other aromatic amines interacted with highly active aldehydes, that were present in fruiting bodies. Among them 2,2-dimethylocta- 3,4-dienal was the most stable and was present in the biggest quantity. This substance very rarely occurs in the vegetable kingdom and in fungi extracts of Lactarius genus wasn’t previously described. Its possible function in fungi is prevention of damage by parasites and eating by animals.
“We fit into this landscape.” : Values and Value Systems in the Postmodern Age
Authors: Gyökér Róbert
Published: February 2021

The fundamental changes brought about by postmodernity have made a profound impact not only on life-style and self-expression but also on the foundations of knowledge. The status of knowledge has changed by gradually shifting from the unifying power of metanarratives to a diversity of personal interpretations. As a result, faith in objective truth has been overthrown by subjectivities and the traditional perception of culture has come under criticism. Instead of a general way of reading, the subjective approach constitutes the decisive factor in interpretation. Value systems are also affected by the changes. Value systems are no longer cast from a single mold, but rather derive from a dynamically changing framework that is shaped by the diversity of the sociocultural situation, the central role of the subject’s interpretation and the positioned meaning of values. This paper will address the impact of postmodernity on values and value systems through the exploration of the inner happenings of a community garden in Budapest. While trying to analyze the components of value systems, I define so-called correlations in the hope of realizing a more relevant understanding of the postmodern age.

Published: February 2021

Introduction: The association of alcohol use with committing sexual offences is well established. However, there are still gaps in knowledge about the mechanisms which lead to alcohol overuse and related sexual violence occurring under the influence of alcohol among this group of perpetrators. Goal: The goal of this paper is to describe characteristics of perpetrators of sexual offences with regards to their self-declared alcohol use status: “overusing” – declaring overusing alcohol, “not-overusing” – declaring not overusing alcohol, and “abstaining” – declaring abstinence from alcohol. Material and Methods: Material for this study consisted of 180 individual forensic psychiatric reports issued by the experts from the Mental Health Clinic at the 10th Military Clinical Hospital in Bydgoszcz. The reports were reviewed by the study authors. Relevant data from was extracted using the survey tool developed for the purpose of this study: “Survey of Factors Determining Sexual Criminal Behaviour” Results: Statistically significant associations between several studied variables were noted and presented in table format, see tables 1-3 for details. Conclusions: Disinhibiting effect of alcohol on sexual offending is associated with coexisting personality disorders and organic personality disorders. Perpetrators of sexual offences overusing alcohol are characterized by poor levels of social functioning and personal history of being raised in dysfunctional families with alcohol problems.
Mitochondrial Capacity and Muscle Endurance in Individuals with Parkinson’s Disease
Authors: Sharma Nivita , Ware Sharma , McCully Kevin
Published: February 2021

Introduction: Parkinson's disease (PD) is associated with loss of motor control and difficulty exercising. This study measured skeletal muscle mitochondrial capacity and endurance in individuals with and without PD using novel non-invasive methods. We hypothesized that individuals with PD will have decreased mitochondrial capacity, reduced oxygen recovery, and decreased endurance compared to controls. Methods: Eight participants with PD and nine healthy controls were tested. Mitochondrial capacity was measured as the rate of recovery of muscle metabolism after electrical stimulation using near-infrared spectroscopy (NIRS) and repeated short arterial occlusions. Oxygen recovery was measured as the half time of recovery of oxygen levels after 5 minutes of ischemia. Muscle endurance was determined from changes in twitch contraction acceleration during electrical stimulation at 2, 4, and 6 Hz. Results: Mitochondrial capacity was lower in individuals with PD compared to controls (1.5±0.1min-1 vs. 1.7±0.1min-1, p=0.02). Individuals with PD had slower oxygen recovery after ischemia compared to controls (8.9±2.3s vs. 5.4±0.8s, p=0.01). Endurance was not different between groups at 6 Hz (PD vs controls: 58±23% vs. 69±16%, p=0.34). The effect sizes for mitochondrial capacity and oxygen recovery were large (Cohen's d >0.8). The Cohen's d for endurance was 1.11. Conclusion: Individuals with PD had slight impairments in mitochondrial capacity and blood flow but did not have reduced muscle endurance. While our study suggests that muscle metabolic dysfunction may play a minor role in exercise intolerance in people with PD, it demonstrates the use of noninvasive technologies to evaluate muscle function in people with neurological disorders.
A comparison of moist heat, dry heat, chemical dry heat and icy hot for deep tissue heating and changes in tissue blood flow.
Authors: Petrofsky J. , Laymon M , Donatelli R
Published: February 2021

Background: Intermittent bouts of heavy activity at greater than normal exercise intensity can cause delayed onset muscle soreness (DOMS). Several products are commercially available, all alleging to reduce DOMS. In the present investigation, 40 subjects (average age 27.0+/-4.4 years, average BMI 26.8) were assessed to determine the effect of 4 of these products on skin and muscle temperature and blood flow during 2 hours of application. These included ThermaCare Dry Heat Wraps, ThermaCare Moist Heat Wraps, Icy Hot Patches, and hydrocollator heat packs. Methods; Blood flow was measured (by laser doppler flow meter) over and in the quadriceps muscle and tissue temperature was measured (by thermistors and thermocouples) in these same areas. Results: The results of the study indicated that only ThermaCare Dry and Moist Heat Wraps both heated the muscle and increased muscle blood flow. The menthol and methyl salicylate compounds in Icy Hot cooled muscle. Skin blood flow increased 300% after the moist heat was applied after 45 minutes, low level continuous dry heat almost 256% but it took 105 minutes to reach this flow, hydrocollator heat wraps increased by 201% but only for only first 45 minutes and then back to baseline, a slight reduction in skin blood flow was seen with Icy Hot gel applied to the skin. Moist heat caused muscle temperature to increase by an average of 3.1 Deg C. Dry heat caused muscle temperature to increase by 2.2 Deg C, while hydrocollator packs increased temperature by 0.4 Deg C. Icy hot had no effect on muscle temperature. Conclusion: Continuous low level heat products had better penetration into muscle and increased blood flow the best compared to hydrocollator heat packs and Icy Hot patches.

With the evolution of cultivation techniques, the world production of fruits and vegetables has been presenting a continuous growth. Despite the increase in production, a significant portion of the harvested products is mainly lost in the post-harvest due to several factors, such as inapropriate handling, transportation and conservation, lack of selection and classification, poorly sized packaging, among others. In general, the quality of fruits and vegetables is usually evaluated by the following parameters: size, shape, mass, color, firmness, ripeness, absence of bruises and pathologies.The objective of this work was to develop an application in Matlab to detect morphological characteristics (width, length, area, perimeter) of Mangifera indica L., ‘Tommy Atkins’ mangos from images, and using the same images, estimate its weigth. The images of the mangoes were acquired with a digital camera attached to an illuminated box and later processed in an application developed in Matlab. The images showed the morphological characteristics of the samples were obtained and an equation was determined to estimate their mass. The determination of the mass from the images had a 96% correlation with the actual mass measured with a scale and it was possible to obtain a reliable estimate of the masses of the mangoes from their images.

This paper is dedicated to the mathematical analysis of an axisymmetric, steady Newtonian fluid flow through a horizontal pipe within the occurrence of radiation, Dufour, and Soret effects. The flow is exposed to associate outwardly functional constant suction above the pipe along Z-direction. The homotopy analysis methodology (HAM) is utilized to get semi-analytical solutions for the coupled differential equations. The results of diverse rising constraints on velocities, thermal and solutal are discussed and pictured. The flow is studied through streamlines, isotherms and pressure contours area unit likewise shown as pictured. It is identified that the temperature can increase with an increase in Dufour parameter but decelerates with an improvement in the radiation parameter. For the given increase within the Soret number, the concentration decelerates.

Published: January 2021

Background: Animal models and observational studies have suggested a favorable role of vitamin D in male reproduction. However, randomized clinical trials investigating the effect of vitamin D supplementation on male fertility are limited. Therefore, this study aimed to examine the effect of vitamin D supplementation on semen quality, reproductive hormones, and anthropometric measurements in vitamin D deficient males with Asthenozoospermia.
Methods: Forty-four males with infertility were randomly assigned to the vitamin D group (DG, supplemented with 9 pearls of vitamin D containing 50000 IU vitamin D3 once a week for 12 weeks) and placebo group (PG, received 9 pearls of placebo once a week for 12 weeks). Semen quality markers (sperm count, morphology, sperm motility, semen volume), total testosterone, sexual hormone binding globulin (SHBG), free androgen index (FAI), and anthropometric measurements (weight, body mass index (BMI), waist circumference (WC), hip circumference (HC), and waist to hip ratio (WHR) were measured at the baseline and the end of the study.
Results: Serum 25-OH-D levels were significantly higher in the DG compared with the PG. In a multivariate adjusted model, WC significantly decreased in the DG in comparison to the CG (-0.90 ± 0.67 cm VS 0.49 ± 0.38 cm). A marginally-significant increase was observed after vitamin D supplementation for SHBG compared to the baseline value in DG (11.69 ± 5.79, P = 0.05). Compared to the baseline value, sperm immotile was decreased after vitamin D supplementation in the DG (-12.35 ± 5.13, P = 0.02). However, no statistical significant differences were observed in the semen quality markers (sperm count, morphology, motility, and volume), total testosterone, free androgen index, and other anthropometric values.
Conclusions: Vitamin D supplementation did not improve semen quality markers, reproductive hormones, and other anthropometric measurements in vitamin D–deficient infertile men compared to the control group.

Published: January 2021

Purpose of the Study: Tourism stakeholders and academics have begun to question the benefits of developing tourism in rural areas. This study aims to identify tourists, tourism entrepreneurs, and employees' characteristics and measure the multiplier effect for local communities in Nglanggeran tourist village, Yogyakarta. Specifically, this study measures income generation (direct, indirect, and induced), employment generation, and the multiplier effect of both. Methodology: This research uses a descriptive quantitative approach. Primary data collection was carried out by the non-participant observation method (for four months). While the technique of determining the sample size (100 tourists, 51 entrepreneurs, and 62 employee respondents) used is non-probability sampling, referring to the Slovin formula with a margin of error of 10%. Main Findings: This study found that local entrepreneurs can be categorized as small and medium-sized enterprises (SMEs). Data analysis results show that tourism village had an important economic impact for local communities with a Keynesian income multiplier effect value of 2.57, 1.74 for the Income multiplier type I ratio, and 2.23 for the type II. While the employment multiplier value is 0.0000041. Implication/Applications: This study's results can answer doubts about the economic benefits received by local communities from the development of the Tourism Village. The originality of the study: This study is the latest research, especially considering the implementation of the multiplier effect formula on a small scale. However, this study has some limitations, such as the sample area used (Desa Wisata Nglanggeran) and the context of the tourism impacts studied. Further research is expected to reach other tourist villages and expand its studies to environmental and socio-culture issues.
MORE THAN FRIENDS: THE IMPACT OF SOCIAL MEDIA ON WORD OF MOUTH, BRAND LOYALTY AND PURCHASE INTENTIONS FOR INTERNATIONAL HOTELS
Authors: Chang Wen-Jung , M. Katrichis Jerome
Published: January 2021

Purpose of the study: Increases in global travel have led to the internationalization of the hospitality industry. Though a number of applications of social media have been examined in the hospitality industry, few of them integrate key dimensions of fan pages into a measurement model in the same time, including interactivity (INT), engagement (ENG), trust (TRT), friendship (FRP), word-of-mouth (WOM) and purchase intention (PI).

Methodology: Based on 408 valid fans from Facebook fan pages of 24 International hotels in Taiwan, the empirical results show that ENG, FRP, TRT, and WOM all act as partial mediators in their impact on post-purchase behaviors. Based on Taiwanese International hotels, this study attempts to explore why these owners want more than just a friend.

Main findings: The empirical results show that ENG, FRP, TRT, and WOM all act as partial mediators in their impact on post-purchase behaviors. The study demonstrates the mechanisms behind utilizing social media to build solid long term potentially profitable relationships with hotel clientele.

Originality/value: We propose and empirically investigate an integrated theoretical framework to more fully capture and describe the consumer’s behavior in the brand community. Our model of the social media process is informed by an “S-O-R” view from consumer behavior, where INT and ENG help create the situation which acts as a stimulus for FRP and TRT which in turn influence BL, WOM, and further PIs. Here, we see the pull force (website INT) as an influence on the brand-consumer relationship (i.e., FRP) through a push force (fan’s ENG). Together and along with the brand content they combine to create the consumer stimulus.

This study explores in a sociological and anthropological perspectives, the efficiency of the policy of registration of customary rights in Côte d’Ivoire, by borrowing from Chauveau (2014: 49), his position on the paradigm of the formalization of customary rights.

The study is essentially qualitative and took place in 5 implementation zones of the pilot phase of the 98-land law in Côte d’Ivoire.

 

Its results that the challenges and causes of  the failure of the land tenure policy of the state of Côte d’Ivoire during the pilot phase of generalization and formalization of the 1198 law.

Finally, it lifts a corner of the veil on the stakes of pursuing this policy through a legal tidying up, because of the sustainability of debt assistance from development partners.

The results of the study analyse successively: (i) the rural land policy, (ii) the pilot and generalization phase of the implementation of the 1998 law, (iii) the determinants of failures, and (iv) the asymmetrical perspectives.
Die Geschichte und ihre Schatten. Neuere Generationserzählungen reflektieren eine vielschichtige Vergangenheit
Authors: Gisbertz Anna-Katharina
Published: February 2021

Generationserzählungen haben sich in der deutschen Sprache als eine erfolgversprechende, aber auch sehr wandelbare Gattung erwiesen. Der einleitende Beitrag fokussiert auf die Fähigkeit des Narrativs, die deutsche und europäische Geschichte mitzugestalten und auch umzuschreiben. Dabei greifen jüngere Werke Vergessenes und fehlendes Wissen auf und verarbeiten weite Zeiträume imaginativ. Durch ihre vielschichtigen Zugriffe auf die Zeit reflektiert die einschlägige Literatur nicht nur über die Vergangenheit, sondern auch grundsätzlicher über den ästhetischen Umgang mit der Zeit und ihre sprachlichen Darstellungsmöglichkeiten.
Fehlzeiten des 20. Jahrhunderts. Narrative Substitute bei HERTA MÜLLER und BIRGIT WEYHE
Authors: Heidemann Gudrun
Published: February 2021

Mit zunehmendem Abstand zum 20. Jahrhundert geraten gerade Zeitlücken in den erzählerischen Fokus und werden als solche thematisiert. Exemplarisch wird an HERTA MÜLLERS Roman Atemschaukel und dessen Entstehung gezeigt, wie Leerstellen im Familiengedächtnis später durch Notizen von und Gespräche mit Oskar Pastior, der wie MÜLLERS Mutter sowjetischer Lagerhäftling war, gefüllt werden. Dies ermöglichte der Autorin, das heimische Lagerzeittabu literarisch ‚stellvertretend‘ durch den fiktiven Schreiber Leo Auberg zu kompensieren. BIRGIT WEYHE hingegen füllt in ihrem Comic Im Himmel ist Jahrmarkt die Fehlzeiten ihrer Familiengeschichte vor allem durch verbal-piktorale Erfindungen, welche gleich zu Beginn des Comics expliziert werden. Darin werden dann Zeitlücken ab dem Beginn des 20. Jahrhunderts derart visualisiert und verbalisiert, dass die Zuverlässigkeit der Narration stets ambivalent bleibt. Der Vergleich beider Werke zeigt Unterschiede wie Ähnlichkeiten im literarischen Umgang mit Fehlzeiten im Familiengedächtnis, aus denen in beiden Fällen ein narratives Substitut hervorgeht.

„Vier Steine seien der Heimat Dank“ – Kriegerdenkmäler und Erinnerungskulturen in Oberösterreich vom Ersten Weltkrieg bis zur Gegenwart
Authors: Gruber Clemens
Published: February 2021

Kriegerdenkmäler spiegeln auf besondere Weise sowohl Brüche als auch Kontinuitäten wider, welche die politischen Umwälzungen des Ersten Weltkrieges, des Dritten Reichs sowie der Nachkriegszeit in der österreichischen Erinnerungskultur hinterlassen haben. Dieser Beitrag widmet sich einer Reihe von Denkmälern einer spezifischen Region in Oberösterreich. Die Analyse der Inschriften führt den ambivalenten und oberflächlich neutralen Charakter von Kriegerdenkmälern vor Augen: Deren sprachliche Botschaften lassen zwischen den Extrempolen ‚Helden‘ und ‚Opfer‘ bis heute kaum Platz für gesellschaftlich schonungslose und gleichzeitig historisch reflektierte Perspektiven auf die Gewaltexzesse des 20. Jahrhunderts.

Problem solving, creative thinking, and reasoning skills are important skills for students to master to solve various problems that they will face in the future. However, there are still many students that have relatively low ability levels performing these three skills. To improve students' abilities in these three skills, teachers can use learning strategies that incorporate visual learning media. The problem identified in a class of third graders at a public elementary school (SDN 01) in Jagakarsa was the lack of use of learning media in the learning process in the classroom so students' ability in all three skills was less developed. A research study was conducted to determine the increase in problem solving skills, creative thinking skills, and reasoning skills of third grade students at SDN 01 Jagakarsa in math subjects after being taught using instructional media. Data sources were obtained from students' test scores before and after being taught using visual learning media. Based on the N-gain calculation and data analysis using inferential statistics, results showed that the use of visual learning media can improve students' ability to solve problems, think creatively, and reason, especially in mathematics subjects.

BAHASA INDONESIA ABSTRACT: Keterampilan memecahkan masalah, berpikir kreatif, dan menalar merupakan keterampilan yang penting dikuasai siswa untuk menyelesaikan bermacam persoalan yang akan dijumpainya kelak di masa yang akan datang. Kenyataannya masih banyak ditemui siswa dengan kemampuan ketiga keterampilan tersebut yang tergolong rendah. Untuk meningkatkan kemampuan siswa pada ketiga keterampilan tersebut, guru dapat menggunakan strategi pembelajaran menggunakan media pembelajaran. Masalah yang teridentifikasi di kelas III SDN 01 Jagakarsa adalah masih kurangnya penggunaan media pembelajaran yang digunakan dalam proses pembelajaran di kelas, sehingga kemampuan siswa dalam ketiga keterampilan tersebut kurang berkembang. Oleh karena itu dilakukan penelitian untuk mengetahui peningkatan kemampuan memecahkan masalah, berpikir kreatif, serta menalar siswa kelas III SDN 01 Jagakarsa pada mata pelajaran matematika setelah diajarkan dengan menggunakan media pembelajaran. Sumber data didapat dari nilai siswa sebelum dan sesudah diajarkan dengan menggunakan media pembelajaran visual. Berdasarkan hasil perhitungan N-gain dan analisis data menggunakan statistik inferensial didapat kesimpulan bahwa penggunaan media pembelajaran visual dapat meningkatkan kemampuan siswa dalam memecahkan masalah, berpikir kreatif, dan menalar secara keseluruhan khususnya pada mata pelajaran matematika.
Justification of the cost representation services as one of the criteria of reasonableness (excessive) in reimbursement of expenses in civil and arbitration proceedings (problem statement)
Authors: Nazarov Valentin , Volkov Ilya
Published: February 2021

We present a justified position that the definition of reasonableness (excess) in reimbursement of expenses is included in a wider range of problems associated with reasonableness in civil proceedings – problems of a doctrinal nature. We substantiate the argument that the legal nature of the “reasonable limits” for collecting expenses (especially, the justification for the representation services cost) does not have the effect of “pre-reflection” due to a number of objective reasons. We pay special attention to the neces-sity for legal mediation of the problem sector (and, in general, interested par-ticipation from the state, for example, when the Government of the Russian Federation is included in this process), concerning the justification of the cost of legal services for reimbursement of expenses in civil and arbitration pro-ceedings. We list materials of court practice on reimbursement of expenses for payment of the representative's services, confirming the polarity of posi-tions. We reflect other criteria that affect the justification of legal services cost in the context of the problem under consideration. We attempt to answer the question: what are the limits of such legal mediation of the problem sector: is there no risk of legalization in the narrow sense of this concept (excessive legal regulation)?
Análise do desempenho térmico de habitação de interesse social com paredes de concreto em Uberlândia-MG
Authors: Oliveira Roberta Bastos de , Alves Camila dos Reis

O sistema construtivo de paredes de concreto tem sido amplamente utilizado na construção de habitações de interesse social (HIS). No entanto, questões relacionadas ao desempenho térmico necessitam de maiores estudos e atenção. Neste contexto, tem-se a avaliação do desempenho térmico segundo a ABNT NBR 15575:2013 de uma HIS construída com paredes de concreto moldado in loco na cidade de Uberlândia-MG. Inicialmente foi utilizado o método simplificado para avaliação do projeto real para a determinação do nível de desempenho térmico. Em seguida, foram simulados 6 cenários para o verão e para o inverno, de acordo com a orientação solar mais crítica. Para as análises, utilizou-se o software Energy Plus com as 8760 horas do ano. Trata-se de uma comparação entre os resultados obtidos e os requisitos normativos que preveem a comparação das temperaturas internas com as externas, bem como as internas com as temperaturas do dia típico. Como resultados, a HIS não atingiu os níveis mínimos para o método simplificado. Para as simulações, tem-se diversas análises comparativas quanto ao aumento ou redução das temperaturas internas nas zonas térmicas da edificação. O projeto real com beiral e paredes externas na cor clara atingiu o nível de desempenho térmico mínimo para o verão e para o inverno, no entanto, outras análises foram incorporadas possibilitando ponderações importantes. Faz-se uma crítica também quanto aos critérios normativos para desempenho térmico que destoaram entre si e à qualidade dos projetos que têm sido replicados na cidade sem uma preocupação com o usuário.

This study aimed to identify the application level of future thinking skills  among the students of Arabian Gulf University. To investigate this issue the study adopted a descriptive-analytical method. The final sample was (133) male and female students selected from the disciplines of Innovation, Giftedness and Medicine. The researcher developed a questionnaire  consisting of three dimensions: future planning, future forecasting, and solving future problems. The Reliability and validity of the instrument ranged between (0.6-0.8). Results revealed that the application level of future thinking skills in strategic planning by Arabian Gulf University students was 76.96%.  The percentage of using the skills of predicting future variables was 75% as students showed interest in presenting serious future scenarios. Results also showed that level of using  the skill of solving problems was 84.5%. On the other hand, the study results revealed that there is a disparity in the use of an organized method to solve problems and evaluate solutions after taking a decision. Finally, the study recommended conducting continuous training courses in using future thinking skills. It was also recommended to create student work teams in all educational institutions to solve educational and scientific issues. These institutions should also foresee future through these students and offer them capacity building programs.

Keywords: future thinking skills, Arabian Gulf University students.

Synthetic dyes are artificial dyes manufactured by Industry and commonly used for the textile industry. These dyes had potentially caused an environmental problem. Many types of dyes are recalcitrant and have toxic properties for living organisms. It can be removed by decolorization method, especially a biological decolorization by fungi. Fungi were chosen due to the ability to degrade toxic components. Aspergillus sp. is the fungi which commonly used for dye decolorization. It might be caused that Aspergillus sp. is one type of fungi lived in the textile waste and expected not to die in the dye decolorization treatment. The purpose of this research was to investigate the ability of the mycelia pellets of Aspergillus sp to decolorized Indigosol Blue dye and Remazol Brilliant Blue R (RBBR) dye. This research showed that mycelial pellets of Aspergillus sp. had high activity of decolorization of Indigosol Blue dye up to 85.37% and RBBR dye up to 80.21% and caused low pH value after 24 hour incubation time compared to the control solution.
