The credit money banks whose obligation is to contribute money-wise to small and medium scale enterprises (SMEs) to oblige an essential utensil in decreasing the dismal paucity and enhancing pecuniary change in Nigeria. This paper examines the role deposit money banks’ loan facilities plays in funding SMEs businesses in Nigeria. The study employed the cross-sectional method of survey research. Ten (10) years financial performance index report of SMEs businesses was extracted from the Central Bank of Nigeria (CBN) statistical bulletin between the periods of 2008 – 2017 were selected. The index captured dependent and independent variables. Gross domestic product (GDP) is a proxy to SMEs while fund deposit, loan facilities and return on equity were proxies to deposit money banks variable. Data collected was analysed using descriptive statistics and ordinary least square techniques. The study revealed the positive co-efficient value of 17.19434 and 15.84082 for fund deposit and loan facilities variables; and the negative co-efficient value of −3.442694 for the returns on equity variable which affect the growth of SMEs in Nigeria. The recent economic recession experienced in Nigeria also affect SMEs businesses because the return on equity from SMEs was not encouraging. Therefore, financial regulators should adhere to stability and sustainability of fiscal guidelines that will readdress the loan facilities requirements of 65% to SMEs in the nation’s economy. This will aid enhancement of the country’s economy from the deficiency of funds that impedes investment.

The article describes that between research parameters the setting angle of cylindrical milling cutter has the main impact relatively on the direction of book blocks movement.
The Social Furniture of Virtual Worlds
Authors: Ludlow Peter
Published: July 2019

David Chalmers argues that virtual objects exist in the form of data structures that have causal powers. I argue that there is a large class of virtual objects that are social objects and that do not depend upon data structures for their existence. I also argue that data structures are themselves fundamentally social objects. Thus, virtual objects are fundamentally social objects.
Evolution of phytochemical and antioxidant activity of Tunisian carob (Ceratonia siliqua L.) pods during maturation
Authors: Ben Othmen Khadija , Elfalleh Walid , Lachiheb Belgacem , Haddad Mansour
Published: July 2019

The Ceratonia siliqua fruits contain several substances known to have high adaptability to environmental conditions. The aim of this paper is to evaluate the changes in physicochemical properties of different Tunisian provenances of carob pulps harvested at three ripening stages. Furthermore, six provenances were investigated during the ripening process in terms of their moisture, ash, minerals, bioactive compounds, antiradical activity and sugar profile. The results demonstrated that all examined parameters are highly influenced by geographic origin. Concerning ripening impact, our data showed that water and ash content significantly decreased during the development of six provenances, as well as the bioactive and mineral contents. Thus, the total polyphenols (TP), total flavonoids (TF) and condensed tannins (CT) contents exhibited the highest levels in the unripe fruits. The antiradical activity trend was positively correlated to the behavior of the bioactive compounds content. Moreover, the sucrose, glucose and fructose were the main sugar qualified and quantified in carob pods at different ripening stages. At the maturity stage, the monosaccharide contents (glucose and fructose) were slightly reduced, while, the sucrose was rapidly accumulated. In conclusion, the ripening process diversely affected the nutritional composition and generally extended the exploitation of carob fruits. The study could provide valuable information about the suitability of carob pods at different maturity stages as potential biomaterials for nutraceutical applications.
Optimization of in vitro asymbiotic seed germination protocol for Serapias vomeracea
Authors: Acemi Arda , Özen Fazıl
Published: July 2019

Serapias vomeracea is an economically important orchid species which is over-collected from nature, because of its glucomannan-rich tubers. Thus, optimization of in vitro culture methodology in this species is required to meet industrial needs and to secure its populations in nature. This study aimed to optimize the surface sterilization protocol for S. vomeracea seeds and to select the optimal seed germination medium by comparing the commonly used media in in vitro orchid culture. During seed surface sterilization, ethyl alcohol (EtOH) pre-treatment prior to sodium hypochlorite (NaOCl) treatment increased the disinfection success and viable seed yield when examined using the triphenyl tetrazolium chloride (TTC) seed viability test. Also, low-g force centrifugation as an additional step in the surface sterilization method separated the seeds without embryo from the viable seeds and thereby decreased potential counting errors after incubation. Comparison of media showed that solid Knudson C (KN) medium induced the highest number of germinated seeds. However, seed germination success of Lindemann (LN) and Vacin & Went (VW) media was found to be higher when the media was used in liquid form. Half-strength liquid VW was the only medium that induced higher germination success than the other full-strength media. The highest number of ungerminated seeds was found when using KN medium whereas liquid VW medium gave the lowest number. In general, protocorm formation was triggered when the media were used in liquid form. However, rhizoid elongation was suppressed in liquid media. These findings suggest that this optimized seed surface sterilization method offers a simple and effective alternative to classical methods. Additionally, solid KN medium may be considered as a cost-effective and reliable alternative to other commonly-used complex media in S. vomeracea cultures.
The current state and efficiency use of in situ and ex situ conservation units for seed harvesting in the central part of Ukraine

Published: July 2019

Significant increase of biological stability, timber volume, and economic value of forests is impossible without refinement and improvement of the organization, and implementation of forest seed production on a genetic and breeding basis. It is possible to solve this task by creating and efficiently functioning in situ and ex situ facilities.

In Ukraine, the basic principles of plus selection are envisaged, which include the selection and testing progeny of plus trees. The total number of progeny tests in Ukraine is 106 plots, in which 1,079 genotypes of plus trees are presented. Taking into account the total number of plus trees in Ukraine (4,560), only 23.7% was subjected to progeny tests. The largest number of progeny tests are represented by Scots pine (Pinus sylvestris L.) – 76 plots and a significantly smaller number of plots for English oak (Quercus robur L.) – 21. The corresponding representation of genotypes is for pine – 520, for oak – 365.

The area of tree breeding units in Ukraine is very small (0.4–0.6%) of the total forest area in the region. Despite the available areas, the use of in situ and ex situ objects for harvesting seed in Ukraine is low, around 30%. In the central region of Ukraine, the share of in situ and ex situ objects from the total forest area is 0.1–0.5%. On these sites, from 0 to 54% is harvested, which is insufficient.

According to the results of the conducted research, it was established that the areas of permanent forest-seed base (in situ and ex situ units) are insignificant and their use is insufficient. Testing of more than 70% of the selected plus trees is required. An important trend is to study the genotype-environment interaction in connection with trends of global climate change.
Cognitive Contagion: Thinking with and through Theatre
Authors: Cook Amy
Published: July 2019

Theatre offers an opportunity for communities to think with and through fiction. We come together to hear and tell stories because it is moving, both in the literal and the figurative sense: it changes us. Theories from cognitive science of embodied cognition make clear that making sense of theatre is a full-bodied affair. In this essay, I argue that we can see moments when theatre invited its audience to think in new ways by shifting theatrical conventions. I explore how a contemporary production of Hamlet, Pan Pan’s production of “The Rehearsal: Playing the Dane”, brings its audience to question the stability of the self and text by altering the conventions around casting and representation. This is theatre that I may not understand in a traditional way, but this gives me a way to understand a new way of thinking about the world around me. It is theatre I can use.
Representation and Immersion. The Embodied Meaning of Literature
Authors: Patoine Pierre-Louis
Published: July 2019

This article explores the relations among three forms of representations (artistic, mental, and neural) and immersion, considered as an altered state of consciousness, in the context of literary reading. We first define immersive reading as an intensification of our embodied experience of literary representation, in accordance to neuropsychological studies about embodied cognition. We further consider the style of interpretation demanded by such immersive reading and its ethical and ecological underpinnings.

Published: July 2019

This paper deals with the behaviour of cement paste upon the addition of crushed polystyrene foam. Crushed polystyrene foam waste with a fill density of 13.97 kg/m3 and hydrated lime were used to prepare the foam. Three different types of samples S-1, S-2, and S-3 were prepared to observe the behaviour of cement pastes after the addition of different doses of foam in constant water/cement ratio. The volumetric ratio of EPS and cement paste were 1: 1.294; 1: 0.863; and 1: 0.647. In each type of sample, 0.28 water/cement ratio is maintained. Slump test was carried out in the fresh state and it has been found slump value was decreasing by increasing foam content in concrete sample. On the 7th and 28th day of curing process, the compressive strength test was carried out. Compressive strength and density of concrete samples also decreasing by addition of higher foam content. In addition, water absorption test and microscopic analysis tests were carried out on the 28th day of curing process. It has been found from the study that samples thermal conductivity is working proportionally.

Influence of Agricultural Waste Ash as Pozzolana on the Physical Properties and Compressive Strength of Cement Mortar
Authors: Bagcal O. , Baccay M.
Published: July 2019

The increasing demand in cement has inspired researchers in both developed and developing countries around the world to explore and consider alternative materials as partial replacement of cement both in concrete and in mortar. In this study, the influence of agricultural waste, particularly corn cob ash, (CCA) as pozzolanic material or supplementary cementitious material (SCM) on the physical properties and compressive strength of cement mortar was investigated. CCA was used as partial replacement of cement ranging from 0% to 20% by weight at water-cementitious ratio of 0.6 and mix proportion of 1 cementitious: 3 fillers. The physical properties evaluated for the mortar paste were setting time and consistency; and compressive strength of hardened mortar cube. The chemical analysis of CCA was conducted, and results indicated that the CCA used in this study is classified as Class C pozzolana with combined SiO2 + Al2O3 + Fe2O3 of 55.86%. The addition of CCA increases the initial and final setting time. The study also revealed that the addition of CCA in the mortar mix reduces the plasticity or fluidity of the paste. Further, the result indicated that the compressive strength of mortars with CCA decreased as the amount of CCA replacements increased in the mixture. The mortar pastes with varying amount of cement replacements, however, are superior for use as mortar for masonry construction.
System Analysis of Reliability Theory Foundations
Authors: Bazarov S. , Belenkiy Y. , Martynov B. , Soloviev A.
Published: July 2019

The relevance of the problem under study is attributed to the need to enhance reliability of the complex engineering systems used in forestry, agriculture, transport, machine engineering, etc. The purpose of the article is to build a mathematical model that would generalize reliability theory fundamentals from a perspective of the theory of dynamic systems based on the symmetry group concept determined by the probability function – dependence of no-failure (failure) probability on external time for system elements. The new approach to study this problem implies building of a multiplicative group under multiplication between no-failure (failure) probability rates as a number of units of the probability measure per unit of external (physical) time and the rate of functional (internal) time as the amount of external (physical) time per unit of the probability measure. The range of probability measures is [0, 1]; it is counted by the unit of measure defined by a set of elementary events. Based on the combination of functional times determined for each element of the system, the system becomes a single deeply integrated structure bound with external and internal time. Traditional reliability criteria of dynamic systems in the “space – time” functional space are dually related to their analogues in “functional time – probability”. Information credibility of the system dynamic state is enhanced by introducing additional confidence intervals of no-failure (failure) probability in conjugated times and their analysis. This study is intended for engineers, graduates, and students of technical universities.

The phenomenon of wisdom is described on the basis of teachers’ values and experience. According to the teachers, wisdom comprises several aspects and is viewed as a dynamic process. The conclusions reflect the integrity of the phenomenon of wisdom, as well as the importance and prospects of further study of wisdom for its use in the work of teachers.
Trust in the Acquisition of Life Experience of Children Left without Parental Care
Authors: Gorina Maritana , Šukste Ņina
Published: July 2019

The children’s trust determines the relationship between various nuanced emotions and the general attitude towards themselves and the world. Children left without parental care are already subjected to negative experience from childhood, which creates a basic mistrust in people and the world. They have experienced psychological trauma, and often not only one. The authors consider this issue to be topical since children who are left without parental care lose their foundation of trust, and they do not develop productive relationships with their fellow human beings and are unhappy because these children have lost confidence during their life experience. Children who are left without parental care often have to change their living conditions from crisis centres and boarding schools to orphanages and, at best, they are immediately placed in a foster home. These children live in fear because experience shows that they often have to separate from the person they trusted, which has a persistent impact on the child in the process of acquiring a sustainable life experience. Trust builds on the quality of past life experience, relationships with relatives, other adults, friends, foster family, and other stakeholders. Trust is very important. It is very difficult to create deep trust, but very easy to break its fundamental basis. For children who are left without parental care, trust means the belief that the world and people are predominantly good, and the belief that they are good for this world. For the action research, the authors chose a target sample of respondents that interacted with the research, action, and evaluation and comparison of the results obtained in order to find out how the phenomena of trust affected the acquisition of future life experience by children left without parental care.
Textbooks as Resources for Education for Sustainable Development: A Content Analysis
Authors: Mohammadnia Zhila , Moghadam Farzane Deliery
Published: July 2019

If we intend to successfully integrate Education for Sustainable Development (ESD) in the general educational programs, it is important to utilize available methods and resources. This paper argues that English Language Learning textbooks in Iran have the potential to be useful resources and a viable springboard for the implementation of ESD. For this purpose, the present study explores the content of English textbook series developed by Iranian authors through the lenses of ESD. The framework for analysis was based on UNESCO’s Earth Charter and the Roadmap for Implementing the Global Action Program on ESD. The findings reveal that the themes of sustainability are present in these English textbooks to a good extent. However, the results suggest that there must be a more even distribution of such themes throughout the series. Also, the role of the teacher as a facilitator in developing discussions around such themes is highlighted.
Management of hazard of flooding in arid region urban agglomeration using HEC-RAS and GIS software: The case of the Bechar's city
Authors: Bekhira Abdelghani , Habi Mohammed , Morsli Boutkhil
Published: July 2019

During the last few years, the City of Bechar in Algeria has witnessed some extreme events, such as the great flood of the year 2008 in which an exceptional amount of rain was recorded with a flow rate of 830 m3∙s−1 (hwater = 4 m, b = 200 m); similar flooding also occurred in 2012 and 2014. The problem is that most of the City of Bechar has an urban sprawl that extends to the banks of Wadi Bechar, which represents a huge risk for the lives of the inhabitants of the region. The present work aims to assess the flood risk through flood hazard mapping. This method consists in determining the flow rates for the return periods of 25 years (Q25 = 388.6 m3∙s−1, hwater = 3.5 m, b = 200 m, Sspot = 55.35 ha), 50 years (Q50 = 478.3 m3∙s−1, hwater = 5 m, b = 200 m, Sspot = 66.48 ha) and 100 years (Q100 = 567.3 m3∙s−1, hwater = 7 m, b = 200 m, Sspot = 133 ha). For this, it is necessary to adjust the flow rates using Gumbel law along with some computer supports such as HEC-RAS, HEC-GeoRAS and ArcGis for mapping the event. Finally, this work enables us to determine the zones exposed to risk of flooding and to classify them according to the flood water height.
Applying results of the chemical analyses in determining groundwater quality for drinking, agricultural and industrial uses: The case study Rafsanjan plain, Iran
Authors: Jahangir Mohammad Hossein , Soltani Keyvan
Published: July 2019

Based on chemical analyses, the quality of ground waters for drinking, agricultural and industrial purposes was determined in Rafsanjan Plain-Iran. Samples for analyses were taken from 22 wells in 2012. Because of high water hardness and total dissolved solids content, water was found to be unsuitable for drinking purposes. Water quality for agriculture was determined with the use of the Wilcox method. Among the analysed water, 10.33% were attributed to C3-S1 class (high electrolytic conductivity and low sodium adsorption ratio), 59.5% to class C4-S1 (very high EC and low SAR) and 30.17% to class C4-S2 (very high EC and medium SAR). 89.67% of studied wells were unsuitable for agriculture. Because of corrosive water properties all but two wells on Rafsanjan Plain were undesirable for use in the industry. The results of qualitative analyses were presented in GIS and in databases to support making decision and management of groundwater on Rafsanjan Plain.
Interpretation of the results of monitoring of the piezometric measurements of the Chańcza dam in 2014–2017
Authors: Lach Stanisław K.
Published: July 2019

The occurrence of a hydraulic connection between piezometers is identified based on similar changes in water levels. Some piezometers react to changing upper or lower water levels, some may also react to atmospheric precipitation. If the reaction to variable upper water levels is significant, then leakage of seepage control devices is identified and the dam is subjected to repair works. The aim of this research paper is to present and analyse the dynamics of variability of water levels in open piezometers of the Chańcza dam, located at the 36 km of the Czarna Staszowska River in the town of Korytnica in Świętokrzyskie province (Poland). Before the analysis of the piezometric data was commenced, the Grubbs statistical test was used to identify and reject the outliers. The scope of the research includes the data captured between January 14, 2014 and January 13, 2017. A hypothesis was formulated that the change in the trend occurred after the spring of 2015 when the water level in the reservoir was reduced by approx. 1.5 m. Two trend lines were adapted for the water levels of each piezometer using the least squares method – the first one for the period from January 2014 to May 2015, and the second one from June 2015 to January 2017. In this way, two slopes of the linear function were obtained together with an estimation of their errors. These slopes were compared using a statistical parallelism test.

Published: July 2019

Solar radiation (Rs) is an essential input for estimating reference crop evapotranspiration, ETo. An accurate estimate of ETo is the first step involved in determining water demand of field crops. The objective of this study was to assess the accuracy of fifteen empirical solar radiations (Rs) models and determine its effects on ETo estimates for three sites in humid tropical environment (Abakaliki, Nsukka, and Awka). Meteorological data from the archives of NASA (from 1983 to 2005) was used to derive empirical constants (calibration) for the different models at each location while data from 2006 to 2015 was used for validation. The results showed an overall improvement when comparing measured Rs with Rs determined using original constants and Rs using the new constants. After calibration, the Swartman–Ogunlade (R2 = 0.97) and Chen 2 models (RMSE = 0.665 MJ∙m−2∙day−1) performed best while Chen 1 (R2 = 0.66) and Bristow–Campbell models (RMSE = 1.58 MJ∙m−2∙day−1) performed least in estimating Rs in Abakaliki. At the Nsukka station, Swartman–Ogunlade (R2 = 0.96) and Adeala models (RMSE = 0.785 MJ∙m−2∙day−1) performed best while Hargreaves–Samani (R2 = 0.64) and Chen 1 models (RMSE = 1.96 MJ∙m−2∙day−1) performed least in estimating Rs. Chen 2 (R2 = 0.98) and Swartman–Ogunlade models (RMSE = 0.43 MJ∙m−2∙day−1) performed best while Hargreaves–Samani (R2 = 0.68) and Chen 1 models (RMSE = 1.64 MJ∙m−2∙day−1) performed least in estimating Rs in Awka. For estimating ETo, Adeala (R2 =0.98) and Swartman–Ogunlade models (RMSE = 0.064 MJ∙m−2∙day−1) performed best at the Awka station and Swartman–Ogunlade (R2 = 0.98) and Chen 2 models (RMSE = 0.43 MJ∙m−2∙day−1) performed best at Abakaliki while Angstrom–Prescott–Page (R2 = 0.96) and El-Sebaii models (RMSE = 0.0908 mm∙day−1) performed best at the Nsukka station.
Implementation of Inclusive Education in Schools Under Local Government Jurisdiction: A Study of South Kalimantan Province in Indonesia
Authors:   Amka
Published: July 2019

This paper examines the practice of inclusive education in schools under the jurisdiction of South Kalimantan Province, Indonesia. According to law, the education system must be inclusive; therefore, schools are required to acknowledge all groups of kids, incorporating those with special educational needs (SEN). This study highlights the state of inclusive education in schools, which includes the implementation of its policies by school administrators, proper management by teachers, and the community’s perception. Primary data were obtained from surveys and interviews with 100 school administrators, 500 teachers, 45 parents of SEN students, and numerous stakeholders. The study shows that local government policies have resulted in the development of inclusive education in schools located in South Kalimantan. It also indicates that, most school leaders and parents of non-SEN students support its utilization in classrooms, and are willing to work with SEN students. In practice, the implementation of inclusive education varies from one school to another depending on the perceptions of administrators and the will of teachers.

Privatisation of Public Enterprises in Nigeria: Challenges and Prospects on Economic Development
Authors: Nwali Anthony Chukwuma , Johnson Nwokeiwu , Oganezi Bethel
Published: July 2019

Privatisation plays key roles in restructuring economic and social attributes of developing countries. The performance of any economy in terms of growth rate and per capita income have always been based on and associated with active involvement and participation of the private sector. It is apt to note that public enterprises in Nigeria have failed to demonstrate strong desire and ability to promote economic growth perhaps due to ineptitude of the managers and inadequate clear-cut operational guidelines establishing such enterprises. This effort attempts to evaluate the importance and implications of privatisation of government’s companies with respect to economic development. The analytical tool adopted in this paper is descriptive that focussed on review and evaluation of privatisation exercise in Nigeria. Findings indicate that corruption, indiscipline, suspicion, transparency and national sovereignty among others were the major challenges of privatisation in Nigeria. Aligning with the new order of moving poor resource utilization to more innovative and creative initiatives orchestrated the call for privatisation in Nigeria in addition to productivity improvement, increase in revenue, reduction in budget deficits as well as elimination of wastes and improvement of efficiency. The paper concludes by advocating for appropriate reform policies of all inclusiveness and transparency that offer full information about the company slated for privatisation and the attributes of core investors to quell misinformed ideas and suspicion.

The assumed idea of UAV was shown in comparison to the currently used aircraft configuration presented in the introduction. Referring to momentum theory, hover efficiency of the multicopter and the helicopter was evaluated. In relation to the helicopter, an initial draft of the airframe conception accompanied by a description of advantages of the gyrodyne configuration was exposed. Problems related to the gyrodyne configuration were emphasised in the summary.
Analysis of Methods Used to Eliminate the Propeller Slipstream Effect in Single-Engine Aircraft
Authors: Popowski Stanisław , Dąbrowski Witold
Published: July 2019

Propeller-driven single-engine aircraft are affected by unsymmetrical flow of air around the fuse-lage, and especially around the vertical stabilizer [1-3]. This unsymmetrical, propeller-induced slip-stream produces sideslip [4,5] that needs to be compensated by the pilot using the rudder [6]. In order to relieve the pilot from this additional task, automatic rudder deflection systems are used that compensate for sideslip by trimming the rudder accordingly. Such compensation algorithms are based on flight parameter measurements.

This paper presents more complex systems used to eliminate the phenomenon in question. In addition, it analyzes the existing solutions, based on patents divided into two groups. The first group deals with active slipstream effect compensation solutions, based on aircraft movement parameters that are derived from aircraft performance characteristics defined in advance. The other group comprises solutions that are based directly on feedback containing actual or estimated sideslip angle values. The most advanced systems rely on a combination of the two methods described above.

Authors: Gęca Michał , Pietrykowski Konrad , Rosiński Karol
Published: July 2019

This paper presents the methodology and investigation of the sound power level produced by a radial piston aircraft engine operating at varied speeds. The research model aircraft engine of a maximum power of 5.5 kW with a two-bladed airscrew was placed on a test bend. Its sound power level was calculated from the sound pressure level measured at 9 measurement points distributed on a hemispherical surface in a confined space in line with PN-EN 3744. Mean sound power generated by the ASP FS400AR engine is 96 dB at idle (2,880 rpm) and 105 dB at a cruising speed (4,740 rpm). Accordingly, it can be concluded that a sound level meter registered a higher sound power level at the points in front of the model aircraft engine than at the points behind it, whereas the lowest sound power level was registered directly above the engine.

Published: July 2019

This paper presents a concept of a small scale liquid-propellant rocket engine designed in AGH Space Systems for sounding rocket. During preliminary design of thermal aspects various ways of cooling were evaluated and described. Possible issues and design approaches for ablative, radiation and regenerative cooling are raised. The authors describe available solutions. Regenerative cooling is especially concerned as it is most popular solution in bi-liquid engines, in which alcohol fuel acts as coolant and is preheated before it reaches combustion chamber. To estimate a possible temperature distribution - and thus an applicability of such a system in the engine - a mathematical model of heat transfer was developed. Unique element of said engine is its oxidizer - nitrous oxide, which have been rarely used to date. Comparison between typical LOX bi-liquids is given and major differences that affect cooling arrangement are discussed. The authors compared different combinations of coolants, fuel/oxidizer ratios etc. to optimize the temperature distribution which is a key factor for the engine performance.
Dutch Caribbean Poetics in a Historical Perspective
Authors: Rutgers Wim
Published: July 2019

This article provides an overview of two hundred years of Dutch Caribbean poetics: from Eurocentrism to originality, from imitation towards creation.

In the 19thcentury colonial poets of the ABC islands followed European examples, in the beginning of the 20thcentury they searched for local themes and forms, and from the last decades of the 20thand in the beginning of the 21st centuries they combined the local and the global arriving at a creative amalgam of the glocal.
Métodos hiperbólico y Asaoka, otros usos. Caso del equilibrio de la humedad de suelos no saturados. Aplicación.
Authors: Martín Ruiz Miriam , Asanza Izquierdo Enrique
Published: July 2019

Este artículo presenta la validación práctica del método hiperbólico y el de Asaoka para predecir la humedad final a la que llegaría una muestra de suelo tras someterla a una cierta succión matricial; basta con disponer de varias determinaciones de humedad durante el ensayo. Se logra así acortar muy notablemente los tiempos de los ensayos de succión sin apenas pérdida de precisión en su determinación. Para ello, se han analizado 3 referencias bibliográficas de ensayos de succión matricial en suelos y una serie de ensayos propios, específica para los propósitos del presente artículo. El artículo describe los 4 suelos y las técnicas de succión empleadas y presenta, para las diferentes succiones, los registros de la evolución de la humedad empleados. El análisis de éstos evidencia que ambos métodos, y en mayor medida el hiperbólico, permiten predecir la humedad final de las muestras a partir de registros tempranos. Adicionalmente, el buen ajuste con el método de Asaoka sugiere que la difusividad hidráulica, D(θ), parámetro que rige la velocidad de este proceso de difusión de humedad, es poco variable durante el ensayo. Por ello, se propone este método para estimar D, difícil de determinar experimentalmente. El desarrollo teórico de los dos métodos se recoge en un artículo previo.
Criterion-related Validity of Forced-Choice Personality Measures: A Cautionary Note Regarding Thurstonian IRT versus Classical Test Theory Scoring
Authors: Fisher Peter , Robie Chet , Christiansen Neil , Speer Andrew , Schneider Leann
Published: July 2019

This study examined criterion-related validity for job-related composites of forced-choice personality scores against job performance using both Thurstonian Item Response Theory (TIRT) and Classical Test Theory (CTT) scoring methods. Correlations were computed across 11 different samples that differed in job or role within a job. A meta-analysis of the correlations (k = 11 and N = 613) found a higher average corrected correlation for CTT (mean ρ = .38) than for TIRT (mean ρ = .00). Implications and directions for future research are discussed.

Creativity is an important aspect in building a good culture of education. Good creativity is shown by the learning outcomes that not only focus on improving cognitive abilities but also on the process of solving a problem either by using divergent or convergent thinking skills. This study was carried out with descriptive quantitative. The study was conducted using two instruments, namely the creativity character scale consisting of 10 items and a set of Verbal Creativity Tests (TKV) consisting of six subtests. The total subjects involved in this study were 470 students who were divided into groups that got the character scale of creativity with the group given the verbal ability test. The results of the study, either through the creativity character scale or verbal creativity tests, show the acquisition of creativity scores which describes that there are still many individuals who have not been optimized in terms of creativity. This becomes a serious concern that can be anticipated by providing information about the importance of creativity. It is also built by creating an instrument that is more effective directly capturing the condition of one's creativity as a whole.
Cultura, identidades e fronteira: Uma abordagem ao pensamento de Manoel Bonfim
Authors: De Souza Filgueira André Luiz
Published: July 2019

Este artigo tenciona examinar – a partir da obra A América Latina: males de origem, do pensador brasileiro Manoel Bomfim – as idéias de cultura, de identidades e de fronteira. A proposta de abordagem deste tema é levantada para que seja instigado o debate em torno da mestiçagem, tese capital que sustenta o projeto identitário de Bomfim na obra supracitada. Pois, o vislumbre do potencial identitário deste elemento, o mestiço, é necessário para que seja potencializada a cultura brasileira. Haja vista que essa discussão busca o reconhecimento do passado colonial ibérico, para que seja refletido o lugar do mestiço dentro da cultura e das identidades brasileiras. Desse modo, o que se quer é compreender como a articulação deste elemento, tão caro ao pensador brasileiro, o mestiço, pode contribuir para o levantamento de uma identidade brasileira que leve a cabo à concatenação de uma cultura nacional e que, por fim, tenha como ponto de partida a fronteira onde essa trama foi urdida, a América Latina.

Entre mineiros, senhores de terra e o Estado: Alianças das montanhas nos Andes sul peruanos (1930 – 2012)
Authors: Carreño Guilllermo Salas
Published: July 2019

As ontologias Quechua pressupõem que os lugares que constituem a paisagem são pessoas dotadas de personalidade, intencionalidade e agência. Os lugares e as montanhas, em particular, são percebidos como agentes sociais ativos e poderosos. Elaborando sobre essa perspectiva Quechu, este artigo explora historicamente as diferentes formas como as montanhas participam em relações de poder na região de Cuzco (Peru). Em primeiro lugar, explora como as montanhas reagem, se opõem e se aliam frente à presença de empresas mineradoras e às comunidades locais no contexto do recente boom mineiro associado às reformas neoliberais dos anos noventa e aos altos preços dos metais. Logo, utilizando textos etnográficos produzidos na região desde os anos trinta, o artigo esboça as maneiras em que as montanhas interagiram com as instituições do Estado, os hacendados, e as comunidades Quechua durante boa parte do século XX, tomando a reforma agrária de 1969 como ponto de partida histórico.
Quando H2O e o espírito da água se encontram: Tornando visível o encontro entre mundos em Puracé - Colômbia
Authors: Martinez Dueñas William Andrés
Published: July 2019

Este artigo busca tornar visível a coexistência de, pelo menos, dois mundos no Resguardo indígena de Puracé através dos percursos (método) que o autor fez nos abastecimentos de água deste território, em companhia do Cabildo Indígena de Puracé. Esses mundos, podem ser exergados mediante duas maneiras de interação com a água. Por um lado, (forma moderna), aquela onde a água é apenas objeto (H2O). De outro, (mundo não[tão]moderno puraceño) aquela onde a água além de objeto tem características de sujeito, como espírito e vontade. Visualizar isto pode influenciar a forma das intervenções contemporâneas de desenvolvimento e as políticas públicas em as nações entendidas como multiculturais.

The present paper aims to present a synthesis of the knowledge already accumulated on the relation between physical exercise and states of humor. Very few studies on physical activity and physical exercise have examined mood or emotion in the perspective of a contemporary theory of emotions. It has yet to be unequivocally demonstrated that acute exercise of the type commonly practiced for leisure or fitness alters emotional responses. The reasons why many people decide to adopt exercise include weight loss and health benefits, including changes in mood states. Adoption of a life healthy style based on physical exercise involves time and a considerable effort in the short term, and visible results do not occur immediately, but rather after a long period of time (months). Advanced motives for exercising have included humor as a factor and, in fact, humor continues to play a significant, conceptually meaningful role as a reason for people to exercise.

The problem of overweight and obesity in various worlds is increasing rapidly. The national prevalence in Indonesia in an adolescent age group is 10.8% (8.3% obesity and 2.5% obesity) caused by inadequate knowledge of nutrition. This study aims to determine the effect of Nutrition Education on changes in body weight of overweight and obese adolescents in SMP Negeri 2 Kota Bengkulu. The type of research is quasi-experimental with pretest and posttest design with control group design. The sample of the study was 11-13 year old teenagers with 44 people using consecutive sampling technique and using Mann-Whitney test and Ancova test. The results showed changes in the mean body weight of adolescents before the intervention of 61.23 kg and the mean body weight of adolescents after being given 61.89 kg of education with the difference in body weight change is only 0.66 kg. There were no significant differences in mean changes in adolescent weight before and after Nutrition Education (p=0.307). Factors that affect Weight Change is pocket money (p=0.044). Parents are expected to manage pocket money so that children can minimize the purchase of snacks that can lead to obesity.
