Published: December 2019

6750 Sayılı Ticari İşlemlerde Taşınır Rehni Kanunu ile birlikte Türk Medeni Kanunu’nun taşınır rehni hükümlerinden farklı düzenlemeler getirilmiştir. Bu Kanun ile birlikte kapsamı daha genişlemiş olan yepyeni bir tescilli taşınır rehni sistemi yürürlüğe girmiştir. Kanunun getirdiği tek değişiklik rehnin kuruluşuna ilişkin olmayıp, borçlunun borcunu ödememesi haline ilişkin de özellikli düzenlemeler getirilmiştir. Buna göre rehinli alacaklı borçlunun borcunu ödememesi halinde rehnin paraya çevrilmesi talebinden önce rehin konusunun mülkiyetini talep etme yetkisini kullanabilmektedir. Getirilen bu yeni düzenlemenin rehin sistemimizin temel prensibi olan lex commissoria yasağına aykırı olup olmadığının tespiti önem arz etmektedir. Çalışmamızda öncelikle lex commissoria yasağının kapsamına ilişkin farklı görüşler açıklanmış, daha sonra ise bu görüşler ışığında getirilen düzenlemenin yasağa aykırılık oluşturup oluşturmadığı konusu olduğu tartışılmıştır. Öncelikle bu husus incelendikten sonra yeni düzenlemenin söz konusu yasağa bir istisna olarak kabul edilip edilemeyeceği incelenmiştir. En son olarak ise, lex commissoria yasağı tanımı ve amacından hareketle, rehinli alacaklının malı satın alma hakkının bu yasak kapsamında yer alıp almadığı üzerinde durulmuştur.
A novel faults detection method for rolling bearing based on RCMDE and ISVM
Authors: Zhang Xin , Zhao Jianmin , Teng Hongzhi , Liu Guozeng
Published: December 2019

The rolling bearing is an essential element widely used in the rotating machinery. Bearing failures are among the main reasons for breakdown of rotating machinery. Therefore, fault detection of bearing is necessary to reduce the probability of breakdown and safety accidents. A novel fault diagnosis method for rolling bearing based on Refined Composite Multiscale Dispersion Entropy (RCMDE) and Improved Support Vector Machine (ISVM) is presented in this paper. The RCMDE is a new irregular index in biomedical signal analysis, which has lower computational cost and more stable results. Therefore, the RCMDE is introduced as fault feature to represent the bearing fault characteristics. After feature extraction, an improved support vector machine based on whale optimization algorithm (WOA) and support vector machine (SVM) is proposed as a fault classifier, which has the advantages of less training samples and good classification effect. The effectiveness of the proposed method in bearing fault diagnosis is verified by using bearing fault experimental data.

Published: December 2019

Graph theory, which has become a powerful area of mathematics, owns much advancement in the field of mathematical chemistry. Recently, chemical graph theory has turned into a very popular area among researchers because of its wide-ranging applications in the field of mathematical chemistry. The manipulation and inspection of chemical structural information is made feasible using molecular descriptors. The molecular topological descriptors are the numerical invariants of a molecular graph and are valuable for predicting their bioactivity. An abundant variety of such indices are taken into consideration and used in pharmaceutical researchers, in theoretical chemistry, in drugs and in several other fields. A topological index actually relates a chemical structure by means of a numeric number. In this recent research work, we have considered the chemical graph of magnesium iodide. We computed degree based topological indices. Mainly, we addressed atom-bond connectivity index (ABC), geometric arithmetic index (GA), fourth atom-bond connectivity index (ABC4), The fifth geometric-arithmetic index (GA5), general Randic' index Ra(G) and First Zagreb index M1(G), Second Zagreb index M2(G) for magnesium iodide, MgI2. Furthermore, the results are analysed and we have provided general formulas for all these above mentioned families of graphs that are in fact very helpful in studying the underlying topologies.

Typology of Behavior of Youth in Situations with a Corruption Component
Authors: Steklova Yu. V. , Petrova E. A.
Published: December 2019

The article features the attitude of Russian youth to corruption. The research owes its relevance to the ubiquitous nature of this phenomenon, which remains understudied from the point of view of sociology and psychology. The article deals with the identification of the prevailing type of personality behavior in various life situations. All the experimental situations were potentially associated with corruption. Three series of studies were conducted in 2018–2019. This research was based on projective methodology. The authors identified the dominant types of behavior of young people in life situations with a corruption connotation. The data obtained indicate that approximately half of the young people were sure that they would remain honest under the suggested circumstances, while less than a half of them admitted that they would possibly get involved in corruption if needed. Only an insignificant percentage of the participants could be classified as susceptible to corruption.
Main Sources of Chinese "Soft Power" in Latin America in the Modern Era
Authors: Garbart M. I.
Published: December 2019

The article covers the fundamentals of Chinese "soft power" in Latin America. "Soft power" now takes an important place in Chinese foreign strategy, both the international level and in Latin America. The author describes the main features of international relations between China and Latin-American countries. The paper focuses on the main sources of formation of positive image of China in the region. The study revealed that Chinese "soft power" has significantly strengthened in the region in recent years. At the same time, the author notes that it is still much weaker than that of the USA. In modern conditions, Chinese government is likely to seek more active application of new forms of international cooperation, promotion of "soft power" being one of them. The methodology of the research was based on the systematic approach, which means considering Chinese "soft power" as a part of the whole foreign policy of China. Theoretical and practical relevance of the study consists in that fact that it creates a basis for further research on this issue. The results can be used to forecast the development of Chinese foreign policy strategy, as well as to study the complex of relations between China and Latin American states.
Archeology: University Textbook and Science (to the 45th Anniversary of the Publication of the Textbook: Martynov A. I. Archeology of the USSR . Moscow, 1973)
Authors: Martynov A. I.
Published: December 2019

The paper features the interaction of archaeological science and textbooks on archeology. It successively examines the history of textbooks on archeology in Russia published for higher education institutions of history, from the XIX century to the present. The author stresses the importance of textbooks in the formation and development of archeology as one of the main subjects of university historical education. Archeology and its textbooks play a key role in the reconstruction of important historical events of the three million years of human history, especially in cases when archaeological materials are the only source. Archeology discovered civilizations of the Ancient East, e.g. China, India, Iran, as well as Archaic Greece and ancient Rome. The paper states the significance of the archaeological heritage of Russia. Since 1970s, only two universities in Russia, Lomonosov Moscow State University and Kemerovo State University (Department of Archeology), have been publishing university textbooks on archeology to be used in universities nationwide. The list involves nine publications prepared by Kemerovo State University. These textbooks are unique from the point of view of the content and methodology of the presentation. The article focuses on the interaction of archaeological science and university textbooks. This concerns the explanation of global historical events, e.g. the early colonization of Eurasia, ethnogenesis in the Middle Paleolithic Era, human migration to America in the Upper Paleolithic, the formation of cultural in the early Holocene, revolution of the producing economy in the Paleometallic Era, etc. The author describes the effect of archeological textbooks on the formation of the conceptual foundations of modern archeology as a historical science. The section "One History – Two Sciences" features the shortcomings of modern Russian historical science, in particular, the lack of alternative to the concept of formational explanation of history in school and university textbooks. History is currently being demonstrated exclusively as a social-class development process, which makes it impossible to understand the role of the fundamental foundations of historical development, as well as the role of discoveries, innovations, achievements in the field of material culture and productive economy. As a result, the human achievements of the past, which are indicated in archeology textbooks, do not find proper application in explaining the historical processes in Russia and Eurasia in modern history textbooks.
Multi-Scale Assessment of Urban Gardens as Constructed Habitats for Biodiversity Conservation in Jeddah, Saudi Arabia
Authors: Middleton Deborah A.
Published: December 2019

Biodiversity in arid urban environments depends upon habitat formation that balances both bioclimatic and biophysical environment needs. There is the potential for urban gardens to establish symbiotic ecosystem services from microhabitat formation that collectively form an assemblage of ecological patches to connect a diverse range of flora and fauna, and establish community driven nursery and seed collection initiatives. This study of urban garden habitats situated within a new urban district of Jeddah Saudi. The analysis concentrates on the ability of garden spatial formations to construct a heterogeneous spatial morphology of sub-patch within the larger urban landscape patch.  Patch and subpatch formations are examined based on the criteria of (I) assemblage of the spatial habitat (characterized by shape and spatial organization); (II) integration of spatial, functional and vegetation plantation patterns; (III) connectivity. Findings reveal that garden layout is structured by the integration and layering of plant types to generate cool understory habitat with seedling establishment, and water conservation. Designed layout of the garden as a spatial pattern is augmented with a range of microclimate mediators to dim solar exposure within the plantation habitat. A strong heterogeneity in plant formations and combinations is seen to dominant the garden formations.
Estrategias de movilidad, visados y fronteras: Trayectorias de haitianos y haitianas hacia la Argentina
Authors: Trabalón Carina
Published: December 2019

En el presente artículo aborda diferentes aspectos referidos a la configuración de las fronteras y el desarrollo de las estrategias de movilidad de haitianos y haitianas que residen en Argentina, desde mediados del 2000 al presente. Las fricciones entre los “destinos ideales” y los “destinos posibles”, los distintos modos en que Argentina se incorpora en la definición de los proyectos migratorios, y las transformaciones que se producen entre las experiencias de cruce de frontera y las regulaciones estatales de control, son algunas de las dimensiones que permiten poner de relieve las tensiones entre movilidad, nacionalidad, racialización y fronteras. Así, desde un enfoque metodológico cualitativo, basado en observación participante y entrevistas en profundidad a haitianos y haitianas en las ciudades de Córdoba y Rosario, se analizan los vínculos entre las estrategias migrantes, sus trayectorias a lo largo del tiempo y la regulación estatal a través de los visados y controles fronterizos. La consideración de estas trayectorias en diversos momentos y espacios muestra cómo las políticas de visados no solo implican claras restricciones a la movilidad sino que, además, su ausencia no se traduce necesariamente en posibilidades de admisión irrestricta a los territorios extranjeros.

Published: December 2019

Introduction:

Neddylation is a highly dynamic and reversible post-translatiNeddylation is a highly dynamic and reversible post-translational modification.
The abnormality of neddylation has previously been shown to be closely related to some human
diseases. The detection of neddylation sites is essential for elucidating the regulation mechanisms of
protein neddylation.onal modification which has been found to be involved in various biological processes and closely associated with many diseases. The accurate identification of neddylation sites is necessary to elucidate the underlying molecular mechanisms of neddylation. As the traditional experimental methods are time consuming and expensive, it is desired to develop computational methods to predict neddylation sites. In this study, a novel predictor named NeddPred is proposed to predict lysine neddylation sites. An effective feature extraction method, bi-profile bayes encoding, is employed to encode neddylation sites. Moreover, a fuzzy support vector machine algorithm is proposed to solve the class imbalance and noise problem in the prediction of neddylation sites. As illustrated by 10-fold cross-validation, NeddPred achieves an excellent performance with a Matthew's correlation coefficient of 0.7082 and an area under receiver operating characteristic curve of 0.9769. Independent tests show that NeddPred significantly outperforms existing neddylation sites predictor NeddyPreddy. Therefore, NeddPred can be a complement to the existing tools for the prediction of neddylation sites. A user-friendly web-server for NeddPred is established at 123.206.31.171/NeddPred/.

Objective:

As the detection of the lysine neddylation sites by the traditional experimental method is
often expensive and time-consuming, it is imperative to design computational methods to identify
neddylation sites.

Methods:

In this study, a bioinformatics tool named NeddPred is developed to identify underlying
protein neddylation sites. A bi-profile bayes feature extraction is used to encode neddylation sites and
a fuzzy support vector machine model is utilized to overcome the problem of noise and class imbalance
in the prediction.

Results:

Matthew's correlation coefficient of NeddPred achieved 0.7082 and an area under the receiver
operating characteristic curve of 0.9769. Independent tests show that NeddPred significantly outperforms
existing lysine neddylation sites predictor NeddyPreddy.

Conclusion:

Therefore, NeddPred can be a complement to the existing tools for the prediction of neddylation
sites. A user-friendly webserver for NeddPred is accessible at 123.206.31.171/NeddPred/.
Study on Physical and Mechanical Properties of Q4 Loess in Lanzhou Rail Transit Area
Authors: Cao Xiaoping , Sun Shoubang
Published: December 2019

Background:

It has been observed that part of the tunnel of rail transit of line 1# in Lanzhou
city passes through loess. Loess has obvious water sensitivity and anisotropy, these obvious
characteristics have different degrees of influence on different projects.

Objective:

This study aims to compare the differences of shear strength with the vertical and horizontal
direction through the triaxial and direct shear test, and permeability of samples in different
directions.

Method:

The Q4 loess undisturbed sample from vertical and horizontal directions near tunnel face
were selected in order to study the physical mechanical properties of Lanzhou rail transit section,
and many related experiments were also carried out.

Results:

The results show that the anisotropy of the shear strength of the surrounding rock (Q4 loess)
is significant near the tunnel face with a depth of 15m. The failure stress in the vertical direction
is 1.33 times to that in the horizontal direction, and the permeability coefficient in the vertical
direction is 1.37 times to that in the horizontal direction. In different directions, the internal friction
angle of loess is basically the same. The cohesion force is different in different directions and different
test methods. In general, the vertical strength of Q4 loess is greater than the horizontal
strength.

Conclusion:

This characteristic is due to the structural characteristics of loess. Therefore, in the
design and construction of loess tunnel, the mechanical parameters in different directions of loess
should be considered, and the influence of different test methods on the measured parameters
should also be considered.

Document-Level Biomedical Relation Extraction Leveraging Pretrained Self-Attention Structure and Entity Replacement: Algorithm and Pretreatment Method Validation Study (Preprint)
Authors: Liu Xiaofeng , Fan Jianye , Dong Shoubin
Published: December 2019

BACKGROUND

The most current methods applied for intrasentence relation extraction in the biomedical literature are inadequate for document-level relation extraction, in which the relationship may cross sentence boundaries. Hence, some approaches have been proposed to extract relations by splitting the document-level datasets through heuristic rules and learning methods. However, these approaches may introduce additional noise and do not really solve the problem of intersentence relation extraction. It is challenging to avoid noise and extract cross-sentence relations.

OBJECTIVE

This study aimed to avoid errors by dividing the document-level dataset, verify that a self-attention structure can extract biomedical relations in a document with long-distance dependencies and complex semantics, and discuss the relative benefits of different entity pretreatment methods for biomedical relation extraction.

METHODS

This paper proposes a new data preprocessing method and attempts to apply a pretrained self-attention structure for document biomedical relation extraction with an entity replacement method to capture very long-distance dependencies and complex semantics.

RESULTS

Compared with state-of-the-art approaches, our method greatly improved the precision. The results show that our approach increases the F1 value, compared with state-of-the-art methods. Through experiments of biomedical entity pretreatments, we found that a model using an entity replacement method can improve performance.

CONCLUSIONS

When considering all target entity pairs as a whole in the document-level dataset, a pretrained self-attention structure is suitable to capture very long-distance dependencies and learn the textual context and complicated semantics. A replacement method for biomedical entities is conducive to biomedical relation extraction, especially to document-level relation extraction.

Authors: YAŞAR Mehmet
Published: December 2019

Aim: This
study was designed to determine the competitive elements that are thought to
have an impact on the ticket prices of low-cost airlines.Method: Using
ticket prices from routes in which Pegasus Airlines operates, a model was
formed to examine the relationship between ticket prices and a variety of
variables including the monthly frequency of the routes, the monthly available
seats, the market share on the route, whether it is a monopoly on the route or
not, the number of airlines operating on that route, whether there is another
low-cost carrier on that route as well as the level of concentration on the
route. Linear regression analysis and T-Test were used to test the model and
reveal the levels of difference.Findings: The
study found that market share, the number of flights on the route and route
concentration values had a significant positive effect on the ticket prices. On
the other hand, the presence of another low-cost airline on the route has a
negative effect on ticket prices. In addition, ticket prices were found to be
higher in monopoly markets and in markets with only one low-cost airline.

Results: The
research is important in terms of examining competitive effects on ticket
prices.

Synthesis of Silica-Salen Derivative from Rice Husk Ash and its Use for Extraction of Divalent Metal Ions Co(II), Ni(II) and Cu(II)
Authors: Attol Duha Hussien , Mihsen Hayder Hamied
Published: December 2019

Rice husk ash (RHA) was used to prepare sodium silicate, which in turn was functionalized with 3-(chloropropyl)triethoxysilane employing the sol-gel technique to form RHACCl. Chloro group in RHACCl was replaced with iodo group forming RHACI. Ethylenediamine was immobilized on RHACI in order to prepare it for the reaction with salicylaldehyde to form a silica derivative-salen. FT-IR analysis indicated the presence of secondary amine and –NH and C=N absorption bands. XRD analysis revealed the occurrence of the broad diffused peak with maximum intensity at 22–23° (2θ). BET measurements showed also that the surface area of the prepared compound is 274.55 m2/g. Elemental analysis proved the existence of nitrogen in the structure of the prepared compound. The silica derivative-salen showed high potential for extraction and removal of heavy contaminating metal ions Ni(II), Cu(II), and Co(II) from aqueous solutions. The kinetic study demonstrates that the adsorption of the metal ions follows the pseudo-second order.

Authors: Sari Putri Luthfiana , Munawaroh Hanik , Wahyuningsih Sayekti , Ramelan Ari Handono
Published: December 2019

Al-doped ZnO (AZO) nanodrums were synthesized using hydrothermal method at 80 °C for 20 h using precursor Zn(CH3COO)2·2H2O and Al(OH)(CH3COO)2 as a dopant by varying the addition of Al concentrations in the range of 0, 1, 5, 10, 15, and 20 mM. The variation of Al can affect structure properties, optical properties and the crystal growths of ZnO. Addition of Al can inhibit the crystal growth with the decrease of the crystal size ranging from about 43.46 to 37.21 nm. Morphology of Al variation doped ZnO of Al was studied using a Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) and showed nanodrums morphology. Optical properties of thin film AZO was evaluated using UV-Visible spectrophotometer. The transmission spectra showed that AZO has ~85% transparency in the visible spectra with a sharp peak in the UV region. AZO with the addition of 20 mM Al has the largest transmittance and the lowest reflectance. The crystallite size of AZO can affect optical properties with the occurrence of blue shift. The thin film with transparent properties is a good candidate for application in the dye-sensitized solar cells, such as anti-reflecting coating. AZO was prepared as anti-reflection on the DSSCs system. The best efficiency of DSSCs performance was examined by varying the thickness of the layers of AZO and pointed an efficiency improvement up to 18.29 times.

Published: December 2019

The present paper deals with the synthesis of cobalt(II), nickel(II), copper(II) and cadmium(II) complexes with two bidentate ligands, L1 (3-(quinoxaline-2-yl)-coumarin) and L2 (2-methylene-2H-chromene-3-(methyl carbonimidic)thioanhydride). The L1 ligand was prepared by treating w-bromo-3-acetylcoumarin with 1,2-phenylenediamine whereas the ligand L2 was prepared through substitution reaction ofw-bromo-3-acetylcoumarin with potassium thiocyanate in ethanol medium. The confirmation of the structures for L1 and L2 were done by (C.H.N.S.) elemental analysis, FT-IR, NMR and mass spectra. The metal complexes of cobalt(II), nickel(II), copper(II) and cadmium(II), with L1 and L2, were prepared and isolated in the solid state then characterized by (C.H.N.M) elemental analysis, proton and carbon-13 NMR, FT-IR and mass spectra. Furthermore, the thermal analysis (TG-DSC) for some complexes assisted us in the elucidation of the suggested structures of complexes and confirmed their thermal stability. The results obtained from elemental analysis, magnetic susceptibility and thermal analysis confirmed that all metal complexes were formed in 2:1 molar ratio of ligand to metal with octahedral structures except cadmium(II) complexes which were in a tetrahedron geometry with 1:1 mole ratio. The complexes are found to be soluble in DMF and DMSO. The results obtained from TG-DSC analysis revealed that the metal complexes were thermally stable with point decomposition over 350 °C. The DFT/TDDFT calculations were carried out to provide the electronic structures and spectra of the compounds.

Process production of floating fish feed in a society constrained by processing technology. The objective of this study was to observe effect of  condition process of twin screw extruders to the physical and chemical properties of produced of floating fish feed. Ingredients used involve fish meal, soybean meal, corn meal, and tapioca flour. The ingredients are mixed with 15, 20 and 25% water added to the total weight. Extrusion process condition conducted by several treatments i.e screw speed (540, 540, 600, 660 rpm) and barrel temperatures (80, 90, 100, 110, 120℃). In order to study, expansion ratio, unit density, floatability and hardness of feed were observed as physical parameters while chemical properties include moisture and protein content. Experimental result showed that addition 25 % water to the formula gives a good performance of expansion ratio, unit density and floatability than 15% and 20% moisture content. Higher of screw speed produces feed with higher ratio expansion, lower unit density, and higher floatability. The optimum of screw speed is 600 rpm.  Meanwhile increasing of barrel temperature caused reduction of unit density, and escalation floatability of feed. Best barrel temperature to meet the physical properties is 120℃. The produced feed contain protein 32.38-41.95% and moisture content 4.37-5.70%.

Authors: Toyin Onanuga Olaronke , Onanuga Abayomi Toyin
Published: December 2019

The need to improve on the use of Fiscal Instruments and engender an improvement in Green Finance remains a challenge in Nigeria. Using the Metcalf’s Framework, this paper explains why Carbon Fiscal Instruments are enforced on emitters to check emissions and their level of effectiveness. Furthermore, a comparative analysis of Nigeria’s performance with some sub-Saharan African countries using the SDGs Index and Dashboard Indicators Framework was discussed. Finally, after appraising the use of Green Finance as a means of innovative finance, the paper found a dearth of fiscal instruments in Nigeria coupled with a low level of Green Finance opportunities. The paper concludes that Nigeria needs to design and implement an optimal climate change fiscal policy and Green Finance mix for Green growth. We recommend that the government needs to encourage creative and innovative ways of generating funds for Green investments in the private sector.

Published: December 2019

Introducción: La indicación de una endoscopia de vías digestivas altas (EVDA) en niños con dolor abdominal crónico (DAC) tiene poca evidencia; sin embargo, se continúa solicitando en niños con desórdenes gastrointestinales funcionales (DGFs). Objetivo: Determinar la prevalencia y posibles asociaciones de DGFs en escolares de una Unidad de Endoscopia Digestiva Pediátrica mediante los Criterios de Roma III. Materiales y métodos: Estudio de prevalencia en 37 escolares. Fueron consideradas variables sociodemográficas, antropométricas y clínicas. El análisis estadístico incluyó estimación de la proporción de niños con DGFs y su correspondiente IC95%, estimación de porcentajes, promedios, desviaciones estándar y rangos, análisis univariado, posible presencia de asociación entre las variables; prueba exacta de Fisher, a dos colas, con un valor de significancia p<0,05. Resultados: La edad media fue de 11,3±2,1 años, siendo un 62,2% mujeres, con una prevalencia de DGFs del 73%, presentando más de la mitad de ellos, dolor abdominal funcional (DAF) y síndrome de intestino irritable (SII). No hubo diferencias significativas en cuanto a las variables sociodemográficas, antropométricas y clínicas. Conclusiones: En niños a quienes se les realiza una EVDA dentro del estudio de su DAC, la prevalencia de DGFs es alta, siendo los más frecuentes el DAF y el SII.

Authors: Barrera-Dussán Nathaly , Ramos-Castañeda Jorge Andrés
Published: December 2019

Introducción: La Organización Mundial de la Salud (OMS) establece los patrones de crecimiento de niños menores de 5 años. Colombia adoptó indicadores antropométricos y puntos de corte para clasificar el estado nutricional. Sin embargo, para desnutrición se considera Peso/Talla en vez del Índice de Masa Corporal (IMC). Objetivo: Identificar la prevalencia de malnutrición en menores de 5 años del área urbana del municipio de Palermo, Huila (Colombia), comparando los resultados con los patrones de la OMS y resolución 2465 de 2016 en el parámetro IMC/Edad. Materiales y métodos: Estudio de corte transversal, con enfoque analítico con 254 niños menores de 5 años del municipio de Palermo. Resultados: Según IMC/edad el 11,81% de los menores presentaron algún tipo de malnutrición: 1,9% desnutrición y 9,8% sobrepeso y obesidad. Un 25,5% estuvieron en riesgo de presentarlo, siendo mayor el sobrepeso (17,7%). Según parámetros OMS el 12,2% presentaron malnutrición: 9,8% por exceso y 2,4% por déficit. El 18,5% y 7,9% tuvieron riesgo de sobrepeso y bajo peso respectivamente. Conclusión: No existen diferencias al comparar la clasificación nutricional entre la Resolución y los parámetros de la OMS.

Authors: Wijayanti Enggar , Fitriani Ulfa
Published: December 2019

Latar Belakang. Anemia merupakan salah satu permasalahan gizi yang banyak terjadi di negara berkembang. Faktor gizi yang turut berkontribusi terhadap kejadian anemia diantaranya adalah kurangnya asupan zat gizi yang memengaruhi pembentukan Hemoglobin (Hb) pada penderita anemia. Tujuan. Penelitian ini bertujuan untuk mengetahui gambaran konsumsi energi, protein, zat besi, asam folat, vitamin C, vitamin A, dan seng pada subjek penderita anemia dibandingkan dengan angka kecukupan gizi (AKG) yang diduga menjadi faktor penyebab anemia. Metode. Penelitian ini menggunakan desain penelitian cross-sectional dan merupakan bagian dari penelitian “Observasi Klinik Formula Jamu Anemia” yang dilakukan pada bulan Maret-Desember 2018. Jumlah subjek sebanyak 83 orang dengan rentang usia 16-49 tahun. Data konsumsi makanan dikumpulkan dengan wawancara menggunakan food recall 24 jam dan selanjutnya dianalisis dengan program Nutrisurvey. Hasil. Hasil penelitian menunjukkan bahwa sebagian besar subjek memiliki status gizi normal. Tingkat konsumsi zat besi, asam folat, dan seng subjek kurang dari AKG, konsumsi energi dalam kategori cukup, dan konsumsi protein, vitamin A serta vitamin C lebih dari AKG. Hasil uji bivariat chi-square menunjukkan tidak ada korelasi yang bermakna antara status anemia dengan konsumsi zat gizi (p>0,05). Kesimpulan. Wanita usia subur (WUS) yang menderita anemia rata-rata memiliki tingkat konsumsi zat besi, asam folat, dan seng kurang dari AKG
Foucault, Normativity, and Freedom: A Reappraisal
Authors: Mascaretti Giovanni
Published: December 2019

The aim of this article is to contribute to the recently revived debate over the normativity of Foucault’s genealogical method. More specifically, I shall respond to Fraser’s charge that Foucault’s rejection of humanism is unjustified because he cannot state why a totally panopticized, autonomous society would be objectionable. After dismissing a non-normative defence strategy of Foucault’s work, I shall proceed as follows: firstly, I shall clarify Fou-cault’s model of critique as a practice of problematization geared to free his addressees from their captivation to the system of truths sustaining the power mechanisms of modern biopolitics. Secondly, I shall argue that Fraser’s society should be resisted because it would reproduce this regime of captivity, thereby obstructing the exercise of freedom as self-transformation. Thirdly, I shall contend that Foucault’s normative orientation to a post-humanist conception of freedom as self-transformation finds a contextual, explanatory account in his attempt to revitalize the emancipatory project of Enlightenment modernity through a transformative problematization of our normative commitments. Moreover, I shall show that the standard of validity of this effort is represented by Foucault’s exemplary embodiment of the critical ethos of the Enlightenment in both his style of existence and theoretical activity. Finally, the article terminates by illustrating three shortcomings of Foucault’s normative approach.

Este trabalho revisita o ensaio de Hannah Arendt ‘O que é autoridade?’, enfatizando o esforço da autora de restabelecer uma autoridade na modernidade calcada no Esclarecimento. Busca também relacioná-lo às reflexões freudianas acerca da autoridade e da educação, tentando mostrar aproximações e diferenças no pensamento dos dois autores sob o pano de fundo do perigo contemporâneo de uma reemergência do totalitarismo.
Risk and perils in LBO transactions
Authors: Capizzi Vincenzo , Giovannini Renato , Pesic Valerio
Published: December 2019

In this study, the risks and perils arising from LBO transactions are considered. By focusing attention on 2,450 deals, for which we compare the performance achieved before and after the deal, our study adds to previous literature that has investigated the post-LBO operating performance and the factors which can determine the success of those deals. In particular, we confirm the hypothesis of the peril of assets stripping, even if we find evidence that the presence of private equity, among other factors, can help to mitigate that issue. We find evidence that, especially in the short term, enterprises suffer from a slight deterioration in operating performance compared to their situation before the buyout. Moreover, under specific circumstances, enterprises experience a slight improvement in the ability to generate cash. Finally, we find positive evidence about the presence of private equity investors, which through their governance are mainly able to promote the growth of firms, as well as to increase the capability to generate cash, together with the hypothesis to generate positive effects on the level of employment. At the same time, we find also evidence that the presence of private equity investors is related in some cases to distress for firms involved in LBO transactions
