International Trade is one of the activities that plays an important role for the economy. Indonesia is one of the countries whose depends on exports. One of the agricultural commodities that become the leading commodity is cocoa. Although it is a main flag export commodity, cocoa farming still has many challenges. The export volume of cocoa beans in the period 1987-2016 increase slightly, but in the last six years the export tend to decrease. The purpose of this study is to analyze the factors that affect the export of cocoa beans. The analytical method used is Multiple Linear Regression with the ordinary least squares rank method (OLS). The results showed that the variables of production have a positive and significant effect with coefficient value of 0.642607. Domestic cocoa price does not affect the export volume of cocoa beans. The international cocoa price variable has a negative and significant effect on export volume of Indonesian cocoa beans with coefficient value of -7,073793. The rupiah exchange rate variable to US Dollar has a positive and significant effect on the export volume of Indonesian cocoa beans with coefficient value of 15.22362. While simultaneously, production variables, domestic cocoa prices, international cocoa prices, and Rupiah exchange rate against US Dollar together affect the export volume of Indonesian cocoa beans.

Authors: AYHAN Fatih , BALAN Feyza , UNVAN Yüksel Akay
Published: March 2020

Globalization is increasing since the mid-1990s. Along with the globalization, increased international trade caused the foreign direct investment (FDI) inflows for economies. Economists often emphasize that FDI contributes developing countries to confront the international competition by boosting their economy, increasing productivity and export capacity. This paper aims to investigate the factors that affect the FDI flows towards the Fragile Five countries (Turkey, Brazil, India, Indonesia, South Africa) for 1994-2017 through panel data analysis. The results from the panel ordinary least square indicate that political freedom as a proxy variable of institutional quality, real exchange rate, and the degree of productive knowledge and capability of the Fragile Five countries are statistically significant determinants of FDI attraction. Thus, developing countries, aiming to increase FDI inflows have to strengthen their political conditions and stabilization of their exchange rates. As well as, it is important to increase these countries’ export shares of the more complex product in order to be able to attract more FDI.

LEADERSHIP CHARACTERISTICS IN THE ERA OF DIGITAL TRANSFORMATION
Authors: KLEIN Müge
Published: March 2020

Digital transformation provoked by Industry 4.0 should not be just seen as a technological issue, it causes also fundamental changes in processes and in organizations of companies. Notably a new understanding of leadership can be counted on to them. The so-called “digital leaders” are expected to act rapidly and flexible in networked and distributed organization structures on the one hand and on the other hand they have to manage the digital transformation of the organization. Since most of the companies are still in the beginning of their digital transformation, there is a lack of a common understanding and a standard model of digital leadership. Most of the existing research works are visionary and predict the requirements for digital leadership on anticipated technological, economical and organizational changes; only few of them report about changes in leadership based on implemented cases. The objective of this study is to sum up main characteristics of the leadership in the era of digital transformation by applying content analysis of literature review as the method.

Published: March 2020

Brown adipose tissue (BAT) plays a critical role in energy expenditure by uncoupling protein 1 (UCP1)-mediated thermogenesis. Carbohydrate response element-binding protein (ChREBP) is one of the key transcription factors regulating de novo lipogenesis (DNL). As a constitutively active form, ChREBP-β is expressed at extremely low levels. Up to date, its functional relevance in BAT remains unclear. In this study, we show that ChREBP-β inhibits BAT thermogenesis. BAT ChREBP-β mRNA levels were elevated upon cold exposure, which prompted us to generate a mouse model overexpressing ChREBP-β specifically in BAT using the Cre/LoxP approach. ChREBP-β overexpression led to a whitening phenotype of BAT at room temperature, as evidenced by increased lipid droplet size and decreased mitochondrion content. Moreover, BAT thermogenesis was inhibited upon acute cold exposure, and its metabolic remodeling induced by long-term cold adaptation was significantly impaired by ChREBP-β overexpression. Mechanistically, ChREBP-β overexpression downregulated expression of genes involved in mitochondrial biogenesis, autophagy, and respiration. Furthermore, thermogenic gene expression (e.g. Dio2, UCP1) was markedly inhibited in BAT by the overexpressed ChREBP-β. Put together, our work points to ChREBP-β as a negative regulator of thermogenesis in brown adipocytes.

Published: March 2020

Embryo implantation is essential for normal pregnancy. Decidualization is known to facilitate embryo implantation and maintain pregnancy. Uterine stromal cells undergo transformation into decidual cells after embryo attachment to the endometrium. Pyruvate kinase M2 (PKM2) is a rate limiting enzyme in the glycolysis process which catalyzes phosphoenolpyruvic acid into pyruvate. However, little is known regarding the role of PKM2 during endometrial decidualization. In this study, PKM2 was found to be mainly located in the uterine glandular epithelium and luminal epithelium on day 1 and day 4 of pregnancy and strongly expressed in the decidual zone after embryo implantation. PKM2 was dramatically increased with the onset of decidualization. Upon further exploration, PKM2 was found to be more highly expressed at the implantation sites than at the inter-implantation sites on days 5 to 7 of pregnancy. PKM2 expression was also significantly increased after artificial decidualization both in vivo and in vitro. After PKM2 expression was knocked down by siRNA, the number of embryo implantation sites in mice on day 7 of pregnancy was significantly reduced, and the decidualization markers BMP2 and Hoxa10 were also obviously downregulated in vivo and in vitro. Downregulated PKM2 could also compromise cell proliferation in primary endometrial stromal cells and in Ishikawa cells. The migration rate of Ishikawa cells was also obviously suppressed by si-PKM2 according to the wound healing assay. In conclusion, PKM2 might play an important role in decidualization during early pregnancy, and cell proliferation might be one pathway for PKM2 regulated decidualization.
¿Sin libertad hay ciudadanía? El ejercicio de la participación formal de la ciudadanía de las personas privadas de libertad en Costa Rica
Authors: Sáenz Solís Jesús , Céspedes Bolaños Dioni Nicole , Barquero Zuñiga Sebastián
Published: March 2020

This article aims to understand how citizen participation is practiced from the point of view of deprivation of liberty and what are the formal mechanisms identified by the legal system, as well as their limitations and scope. The proposal is to reconstruct the main elements that show the evolution of access to formal citizen participation of persons deprived of liberty in Costa Rica. The methodology implemented was the analysis of data from the presidential elections. These considered data were from 1998 (when the population was allowed to vote) until 2018. Besides, data from other types of activities, such as the 2007 referendum and the use of legal tools, such as the electoral appeals filed to guarantee political rights in prisons, were examined. On the other hand, the discussion revolves around the exercise of citizen participation as one of the most studied subjects in the Social Sciences, which, however, has been little explored in the context of populations in high conditions of vulnerability, such as persons deprived of liberty. Therefore, the findings show low levels of participation and presuppose the existence of important limitations, not in access as such, but in the elements that allow the exercise of rights. It is concluded that the guarantees available to the prison population in this area constitute a challenge for the authorities in terms of the exercise of citizenship and national and international normative support.

—A 1.8 m thick core of the Holocene (7.9 14C kyr BP) sediments of Lake Itkul’ (Novosibirsk Region) has been studied. Based on the geochemical and lithostratigraphic properties of the bottom sediments, we have established the following stages of the lake evolution: (1) the beginning of sedimentation, 7.8–7.0 14С kyr BP; (2) extreme shallowing with a probable complete drying, ~7.0–5.5 14С ky BP; (3) rise in the water level, ~5.5–4.3 14С kyr BP; (4) repeated shallowing, 4.3–2.8 14С kyr BP; and (5) subsequent watering, 2.8–0 14С kyr BP. At present, the lake again tends to shallowing. We have established that Lake Itkul’ has mineral sediments with a high content of carbonates (up to 64%). The high concentrations of HCO3– and Ca2+ and stable saturation (S/St > 1) of the surface water cause a shift of the carbonate– calcium equilibrium toward the carbonate formation. The studied authigenic carbonates are aragonite and fine-grained aggregates of poorly crystallized calcite particles with different Mg contents. Aragonite is both biogenic (mollusk and ostracode shells) and chemogenic (formed during the lake shallowing). In addition to carbonates, the lacustrine sediments contain mixed-layer aluminosilicates, feldspars, and quartz. The presence of pyrite throughout the sediment section indicates reducing conditions and the activity of sulfate-reducing microorganisms. Carbonates (especially aragonite) are significantly enriched in strontium. Manganese does not form its own minerals but is present as an isomorphic impurity in authigenic carbonates.

Published: March 2020

Increasing the protein and antioxidant content of food products is a constant challenge amongst researchers. Dried pasta products are popular amongst all groups of society. The most important factor in pasta processing is the quality of the flour. Millet (Panicum miliaceum) flour has high nutritional value, enriching it with cricket (Gryllus bimaculatus)flour is good choice to increase the quality of protein composition and antioxidant properties of products. Flour mixtures of millet and insect flours (5% and 10%) were analysed after mixing and pasta processing. Addition of wheat gluten improved both texture and nutrition value of pasta products. Total polyphenol content, antioxidant capacity, total protein content, free and total amino acid composition were studied. Quality analysis of dried pasta products were carried out according to Hungarian standards. Data was analysed with Kruskal-Wallis test, Dunn's pair-wise post hoc test was used with Bonferroni correction. The correlation was determined by Spearman's rank. Addition of cricket flour modified the pH, acid value, moisture content, and colour of the samples, these changes lasted during storage. Enrichment could increase the total phenol content significantly even at the low level of 10%. Heat treatment during pasta processing had negative effect on the antioxidant capacity except at higher cricket flour contents. Cricket flour's high protein content proportionately increased millet flour's, thus pasta products'. Dried pasta products passed all quality norms. Enrichment of millet flour with cricket flour is favourable from both nutritional and quality aspects.

Authors: Gayas B. , Kaur G. , Singh A.
Published: March 2020

The application of ultrasound during extraction of oil from apricot kernels using hexane was evaluated and compared with conventional methods (mechanical extraction and Soxhlet extraction). Results show that ultrasound assisted extraction (UAE) yields more oil with less solvent consumption. The oil yield from UAE, SE, and ME were 44.72%, 44.33%, and 35.06%, respectively. It is noteworthy that it took 44 min to extract oil by UAE method, while alike yield was obtained from SE in 6 hours. Oil extracted by UAE exhibited significantly higher peroxide and ester values. The functional groups of apricot kernel oil were analysed using Fourier transform infrared spectroscopy. Untreated and treated kernel powders were studied by scanning electron microscopy, and the development of microstructures and disruption of cell walls were evaluated. Our study suggests that ultrasound assisted extraction may be an effective method to extract edible oils by achieving higher efficiency in shorter extraction time.

Published: March 2020

Pickering et al. (Nature 2018;565:226–229) utilised calcium carbonate flowstone deposits (i.e. speleothems) from eight Pliocene and Pleistocene South African Cradle of Humankind cave sites to propose that biases were created within the fossil record due to absent clastic sedimentation phases during wet periods, when caves were closed and only speleothems accumulated. Such a scenario has significant implications for our understanding of variability in hominin mobility, resource exploitation, functional repertoires and interactions with competitors in changing environmental and ecological contexts. We find considerable issues with the article. First, Pickering et al.’s contribution omits crucial fossil evidence from various stratigraphic units of the Sterkfontein Caves that indicates conditions were not always arid when the caves were open and sediments were deposited. Second, Pickering et al.’s proposal that clastic and speleothemic deposits (including faunal and floral material) form mutually exclusively is an overly simplified, binary depositional (and in this case environmental) framework that demonstrates an inherent bias in the sampling of cave deposits for dating. This creates the impression that either speleothems or clastic sediments are deposited and does not take into account the full spectrum of sedimentary complexity in karst caves. Third, closure of the caves across the Cradle of Humankind landscape during wet periods is not substantiated geomorphologically or speleologically; identification of the responsible process is critical to the proposed infilling scenario.
Significance:

We propose that Pickering et al.’s interpretation of the environmental context of the South African early hominin record is problematic in that it omits crucial faunal and floral fossil evidence associating hominins with non-arid climates, is geomorphologically unsupported, and perpetuates biases against temporally and climatically representative clastic sediments due to challenges related to their dating.

An Experimental Study on Stabilization of Expansive Soil Using Steel Slag and Crushed Limestone
Authors: Abdalqadir Zozk , Salih Nihad
Published: March 2020

This study is carried out to evaluate the effect of steel slag (SS) as a by-product and crushed limestone (CRL) as additives on the geotechnical properties of expansive soil. A series of laboratory tests were conducted on natural and stabilized soils. Both of SS and CRL were added by 0, 2.5, 5, 10, 15, and 20% to the soil. The conducted tests are consistency limits, specific gravity, hydrometer analysis, modified Proctor compaction, swelling pressure, swelling percent, and California Bearing Ratio (Soaked CBR). The results showed that the values of liquid limit, plasticity index, optimum moisture content, were decreased. Also, with the addition of the mixture of “10% SS with 10% CRL” which cured for 28 days, the values of swelling pressure and swelling percent were reduced by 69.8% and 84.3% respectively. Whereas, the values of maximum dry density (MDD) increased from 17.66 kN/m3 to 18.79 kN/m3 and from 17.66 kN/m3 to 18.25 kN/m3 with the addition of 20%SS and 15% CRL respectively. Also, with the addition of the mixture of 10% SS+10% CRL and 20% SS+15% CRL individually, the values of CBR increased from 3.4% to 26.7% and from 3.4% to 39.5% respectively. The steel slag and crushed limestone were found to be successfully improving the geotechnical properties of expansive soil.
In plane Shear Strengthening of Clay Masonry Walls with Opening
Authors: Ahmed Sarwat , Abdul-Kadir Muhammad
Published: March 2020

In this paper results of testing eight clay brick wall specimens are presented. Seven of the walls contained opening and one wall without opening. The walls were tested under constant uniformly distributed vertical load and gradually increased lateral load. Six walls were strengthened using the following techniques: reinforced concrete frame around the opening, reinforced concrete frame around the opening with the beam extended to the ends of the wall, steel channel frame inside the opening, reinforced concrete frame confining the boundary of the wall (outside confinement), near surface mounted strengthening with (4) mm steel bar and strengthening with ferro-cement.The test results illustrated that walls strengthened with external frame showed increased lateral load carrying capacity, ductility and toughness compared to non-strengthened wall, and all other strengthened walls showed different ranges of increased shear strength capacity. However, the wall strengthened with ferro-cement did not improve the ultimate lateral load carrying capacity but ductility significantly improved. For the wall strengthened with near surface mounted steel bars, the ultimate lateral load carrying capacity dramatically increased but the lateral displacement did not increase notably.
In-plane Shear Strengthening of Masonry Walls after Damage
Authors: Abdul-Qadir Ahmed , Saeed Jalal
Published: March 2020

This study investigates the effect of 5 different strengthening materials on damaged Un-Reinforced Masonry (URM) brick walls under an in-plane lateral loading and a predefined uniform vertical load. Five clay brick walls with a dimension of (1200 × 935 × 115) mm were tested then strengthened with plastic mesh, glass fiber mesh, steel mesh, wild cane strips, and chopped steel fibers. The walls were tested again up to failure in order to determine the best material in terms of shear strength and ductility. Two more walls were tested similarly without strengthening to serve as control walls. Based on the experimental results, GM-r (strengthened with glass fiber mesh) had the highest ductility factor of 23.2 and showed the best strength retention amongst the strengthened walls. OG-r (strengthened with wild cane grid) had the highest toughness ratio value of 10.1 even though it is not suitable for exterior walls due to biological factors such as rotting and incompatibility with high moisture areas. SM-r (strengthened with steel mesh) retained 89% of the damaged wall and at the same time inadequate in seismic areas due to its sudden brittle de-bonding failure. Walls PM-r and SF-r lacked strength and ductility retention, respectively, to be considered as a feasible option in sustaining lateral loads.

Published: March 2020

The purpose of this study is the investigation of the compatibility of model eliciting activities of secondary school teacher candidates with design principles. This study was conducted in the scope of Mathematical Modelling course with the students who were the secondary school mathematics teacher candidates. The participants of this case study were thirty-nine mathematics teacher candidates who worked in eight groups. The data of this study consisted of eight model eliciting activities which were created within the eight groups and their analysis. The activities created by the groups were analyzed by document analysis method in terms of design principles that were defined for model eliciting activities. It was concluded that the created model eliciting activities satisfied the construct share ability and reusability principle at minimum while they satisfied the reality principle at maximum. The effective prototype principle could not be determined. It can be ensured that the secondary school mathematics teacher candidates gain more experience by making more implementations related to model eliciting activities. The implementation of model eliciting activities in class can be effective in reducing the modelling deficiencies of secondary school mathematics teacher candidates.
