Authors: O. M. Apata O. M. , S. O. W Toluwase , A. O. Awoyemi
Published: May 2018

Inability of fish farmers in Nigeria to produce at a rate that can meet the population demand has been linked to lack of access to crucial information on improved fish farming technique. Information is an indispensable factor in fish farming and it is the basis of extension service delivery. This study was designed to describe demographic characteristic of fish farmers, identify sources of various information to fish farmers and identify information access constraints faced by farmers. Purposive sampling procedure was used to select 2 States and a total of 160 respondents were selected for the study. Descriptive statistics such as frequency, percentage, mean and standard deviation and Chi-Square (X2) was used for inferential statistics. Result revealed that mean age was 44.8 years, 77.5% were male, only 7.5% have no formal education and 98.1% were full time fish farmers. About 25.0% received information frequently, 50.6% rarely while 24.4% never received information from extension agents. Inadequate of extension contact was identified by 88.8% of the respondents as information access constraint. Chi-Square analysis showed significant relationship (X2 = 13.426, p = 0.016) between source of information and utilization of information.

Mindfulness and Self-Compassion Based Interventions for Substance Use Disorders: A Literature Review
Authors: Platt Keith Allen
Published: May 2018

This literature review examines eight peer reviewed studies reporting on the efficacy of mindfulness-based and self-compassion-based interventions for adults diagnosed with substance use disorders. Prevalence of substance use disorders is provided, and relevant definitions are discussed. The syndrome model of addiction is advanced as an etiological explanation, and the search methodology described. Results of this literature review support mindfulness training as an effective intervention for substance use disorders. Only one study supporting self-compassion as an effective intervention for substance use disorders was reviewed so it is not possible at this time to make a judgment regarding the efficacy of that intervention. Limitations of this body of literature include attrition, unmatched treatment conditions, and lack of fidelity measures. Recommendations include more self-compassion research, more use of fidelity scales in intervention research, and greater use of mindfulness-based interventions in substance use disorder treatment.

A noção de escala nos anos iniciais do Ensino Fundamental / The scale’s notion in the early years of Elementary School
Authors: Pommer Wagner Marcelo , Pommer Clarice Peres Carvalho Retroz
Published: May 2018

A escala é um tema matemático trabalhado a partir do 3º ciclo do Ensino Fundamental como uma ferramenta para se construir gráficos cartesianos e mapas.  A presente pesquisa se propôs a verificar se e em que medida é possível introduzir a noção de escala, no âmbito dos números naturais, nos anos iniciais do Ensino Fundamental. Deste modo, elaboramos uma situação de aprendizagem para viabilizar a conversão entre a linguagem natural (o texto), a linguagem aritmética (a operação de contagem) e o registro geométrico (a reta numérica), de modo a ampliar o repertório de compreensão, conforme expõe Duval (2003). A situação de aprendizagem foi aplicada em uma aula de Matemática no 2º ciclo do Ensino Fundamental, de uma escola pública da cidade de São Paulo, no ano de 2011. As manifestações escritas e orais dos alunos revelaram que a conversão entre as linguagens favoreceu introduzir a noção de escala.

Published: May 2018

Este trabalho analisa as práticas pedagógicas presentes no jogo da capoeira, manifestação da cultura popular brasileira oriunda da resistência dos africanos escravizados no Brasil no período colonial. No ensino da capoeira percebe-se que a oralidade é a principal forma de transmissão de saberes, a ancestralidade, através do respeito existente aos capoeiras mais velhos, é uma das principais premissas, ludicidade e musicalidade são características fundamentais. Não podemos nos furtar em mostrar as contribuições que estas pedagogias não escolares podem trazer à educação escolar, promovendo uma profunda reflexão sobre a escolarização, avaliando seus pressupostos políticos, éticos, estéticos e epistemológicos, perpassando pelo currículo a ser adotado, os modelos de avaliação a serem empregados e a didática a ser desenvolvida dentro da prática de ensino, pois todas essas dimensões do educar estão presentes no ensino da capoeira e por vezes se apresentam de formas bem mais inclusivas e respeitosas.

Authors: Patil Maheshkumar Prakash , Noh Eun-Soo , Gun-Do Kim Yeong-Ae Seong,
Published: May 2018

With the discovery of various antibiotic resistant bacteria, evaluations of antimicrobial activities of natural compounds have been preceded on antibiotic susceptible and resistant microorganisms. Several types of natural compounds have been reported to have similar effects on target microorganisms as compared to the widely used antibiotics. Persicaria thunbergii (Polygonaceae) has been known to have anti-tumoral, anti-angiogenesis, anti-oxidation and anti-inflammation functions. In this study, aerial parts of P. thunbergii were extracted using methanol, chloroform, and ethyl acetate to identify possible anti-bacterial effects. Agar disk diffusion method and time-kill assay were done to evaluate the antibacterial effect of P. thunbergii extracts. Two extracts ethyl acetate (EAE), and chloroform (CFE) were tested against Staphylococcus aureus. As a result, the extract from CFE and EAE showed antibacterial effect against S. aureus. The extract EAE showed the strongest inhibition effect compared to CFE. These results demonstrate that the EAE extract which originated from P. thunbergii can probably play a role as an antibacterial agent.

PRESERVICE TEACHERS’ TECHNIQUES FOR GENERATING NEW PROBLEMS
Authors: Fardah Dini Kinanti
Published: May 2018

Evaluating students’ achievement is one significant part of teachers’ pedagogical competency. However, teachers should give problems in vary to their students. The ability of the teachers in developing the new problem from the existing or available problems is necessary to be mastered. This paper aimed to analyze preservice teachers’ techniques in developing new problems. Twenty-nine preservice teachers who had experience in internship program were given three mathematical problems each in probability, trigonometry and number and pattern. They were asked to generate new problems from those problems given. The techniques used by the teachers on generating new problems from the original problems were analyzed and classified as replacement, addition, modification, contextualizing the problem, turning around the problem, and reformulation technique. In summary, teachers are most frequently taking the same given information but changing the problem from the old one. Teachers were still unfamiliar to turn the problem around by taking the end goal as given and the given as the end goal. The implication of this study is lecturers of mathematics education program especially in the subject that contains assessment and evaluation need to consider about developing the preservice teachers’ ability to generate new problems from the old or existing problem given in all types of the development.

Algorithmic Analysis of Cahn-Ingold-Prelog Rules of Stereochemistry: Proposals for Revised Rules and a Guide for Machine Implementation
Authors: Hanson Robert M. , Mayfield John , Vainio Mikko J. , Yerin Andrey , Redkin Dmitry , Musacchio Sophia
Published: May 2018

The most recent version of the Cahn-Ingold-Prelog rules for the determination of stereodescriptors as described in Nomenclature of Organic Chemistry: IUPAC Recommendations and Preferred Names 2013 (the “Blue Book”) were analyzed by an international team of cheminformatics software developers. Algorithms for machine implementation were designed, tested, and cross-validated. Deficiencies in Sequence Rules 1b and 2 were found, and proposed language for their modification is presented. A concise definition of an additional rule (“Rule 6,” below) is proposed, which succinctly covers several cases only tangentially mentioned in the 2013 recommendations. Each rule is discussed from the perspective of machine implementation. The four resultant implementations are supported by validation suites in 2D and 3D SDF format as well as SMILES. The validation suites include all significant examples in Chapter 9 of the Blue Book, as well as several additional structures that highlight more complex aspects of the rules not addressed or not clearly analyzed in that work. These additional structures support a case for the need for modifications of the Sequence Rules.

Abstract:  Aim of this research is to determine spatial
variability of soils, nutrients in soil and yield for sunflower production to
assess variable rate fertilisation. Materials were sunflower field, and GNSS.
Seed variety was Limagrain 5542. Total size of the research field was 35.8
ha. Soil samples were taken from 0-30 cm and 30-60 cm depths.  Soil texture, saturation point (%), pH at
saturated soil, Lime (%), total salinity (%), CaCO3, organic
matter, useful P (P2O5), useful K (K2O),
field capacity (%) and wilting point (%) were determined. Soil texture was
found mostly clay but clay loam and a sandy clay loam texture was also
determined. Mean values and standard deviations for saturation point 57.35%
and 7.44%, pH 7.30 and 0.66, salt 0.07 and 0.01, lime 7.63 and 0.68, organic
material 1.29% and 0.17%, P2O5 18.22 and 2.52, K2O
146.05% and 30.82, field capacity 30.34% and 4.07%, and for wilting point
19.18% and 2.72. Mean yield was 2100 kg/ha. Required fertilisers will be 285
kg/ha Ammonium Sulphate (21%N) and 115 kg/ha Calcium Ammonium Nitrate (26%N)
for constant rate fertiliser application as conventional application. If this
fertiliser is applied as variable rate; amount of fertilisers will be 115
kg/ha Calcium Ammonium Nitrate (26%N) for whole field and 285 kg/ha Ammonium
Sulphate (21%N) should be applied for 250 ha. field size. Urea (46%N)
suggested as 130 kg/ha for 100 ha. According to the results, fertiliser
requirement of the sunflower field is not constant. Fertilisation necessity
is spatially determined. Fertiliser application with spatial variable rate
will increase yield, quality and decrease fertilisation cost and
environmental effects.

Abstract:  Among upmost important effects of climatic
variability and change are the related variations in type, amount and timing
of precipitation at global or regional scales. This aspect causes different
effects from the agricultural point of view. 
Among these effects the drought phenomenon comes to the
forefront.  Efforts on eliminating the
agricultural drought problem are mainly made by irrigation.  That’s why the upmost important portion of
available water is consumed by agricultural irrigation, globally. Concordantly,
the evapotranspiration plays a crucial role on determination of the
irrigation water requirement for agriculture and planning the related
systems. Usage of the methods on direct measurement of actual
evapotranspiration by global means, however; is quite scarce.  In this study, the Bowen Ratio Energy
Balance and micrometeorological Eddy Covariance Methods, which are widely in
use for the measurement of actual evapotranspiration, have been used within
the 2009-2010 wheat growing season in Kırklareli. In conclusion, a
comparative evaluation of these approaches was done for the advantages and
disadvantages by means of their determination abilities of actual
evapotranspiration.

ABSTRACT P

In this study, approaches of the farmers’ to good agricultural
practices and agricultural innovations in Çanakkale province was evaluated. Survey studies were conducted with 55 farmers
applying good agricultural practices in Çanakkale. The same survey was also conducted with the same number of farmers
who did not apply good agricultural practices and total of 110 surveys were
conducted. A great majority of the farmers applying good agricultural
practices (87.27%) were determined as high level innovators and this ratio
was found as 34.55% for the farmers not applying good agricultural practices.
As a result of the chi square test which was done in order to determine the
difference between the farmers applying and not applying good agricultural
practices according to the innovativeness level statistically, it was
determined that the difference between the farmers was statistically
significant in 1% significance level. In the study, 47.27%, 40%, 34.55%, 32.73%, 25.45%
and 10.91% of the farmers stated that they applied good agricultural
practices for the security of the workers, obtaining qualified crop,
receiving subsidy, less damage to the environment, obtaining more crop and
being controlled in each stage respectively. The farmers applying good
agricultural practices stated that marketing guarantee must be given to good
agriculture crops and subsidy amount for good agricultural practices must be
increased. Besides, they stated that studies for informing the farmers about
good agricultural practices can be beneficial.

In the 21st century, the region has gained the world’s attention due to dramatic growth of China’s economy, steady rise of India, the more proactive regional countries, and the increasing oil exports to the region. With such importance, the region has been contested with powerful nations, such as China, India, Australia, Japan, the Southeast Asia nations, and even the United States. China’s increasing military presence in Indo-Pacific has been perceived as assertive by some of the regional countries. Meanwhile, the United States has become a more prominent actor in the region since the application of Rebalance policy in 2012. The paper discusses the issues, challenges and prospects of maritime security in Indo Pacific.
Partial Evaluation of Logic Programs in Vector Spaces
Authors: Sakama Chiaki , Nguyen Hien , Sato Taisuke , Inoue Katsumi
Published: May 2018

In this paper, we introduce methods of encoding propositional logic programs in vector spaces. Interpretations are represented by vectors and programs are represented by matrices. The least model of a definite program is computed by multiplying interpretation vectors and program matrices. To optimize computation in vector spaces, we provide a method of partial evaluation of programs using linear algebra. Partial evaluation is done by unfolding rules in a program, and it is realized in a vector space by multiplying program matrices. We perform experiments using randomly generated programs and show that partial evaluation has potential for realizing efficient computation in huge scale of programs.
Fire Source Localization method based on genetic algorithm
Authors: Hengyi Zheng , Xu Wang , Shanbi Wei
Published: May 2018

In this paper, multiple fire source localization in building environments is approached based on energy distribution of fire by sensor array. A maximum likely-hood estimation method with genetic algorithm is proposed, that describes energy distribution of fire source as Gaussian distribution, and thus derives an energy multi-peak function model and an observation model of sensor nodes. The method facilitates the multiple fire source localization as a global optimization problem, which is explored by genetic algorithm with a global optimal solution. Finally, the simulation result shows the effectiveness of the proposed fire source localization method by the comparison of the traditional EM algorithm and genetic algorithm.
Significance of Bottom-up Attributes in Video Saliency Detection Without Cognitive Bias
Authors: Hosseinkhani Jila , Joslin Chris
Published: May 2018

Saliency in an image or video is the region of interest that stands out relative to its neighbors and consequently attracts more human attention. To determine the salient areas within a scene, visual importance and distinctiveness of the regions must be measured. A key factor in designing saliency detection algorithms for videos is to understand how different visual cues affect the human perceptual and visual system. To this end, we investigated the bottom-up features including color, texture, and motion in video sequences for both one-by-one and combined scenarios to provide a ranking system stating the most dominant circumstances for each feature individually and in combination with other features as well. In this work, we only considered the individual features and various visual saliency attributes investigated under conditions in which we had no cognitive bias. Human cognition refers to a systematic pattern of perceptual and rational judgements and decision-making actions. Since computers do not typically have this ability, we tried to minimize this bias in the design of our experiment. First, we modelled our test data as 2D images and videos in a virtual environment to avoid any cognitive bias. Then, we performed an experiment using human subjects to determine which colors, textures, motion directions, and motion speeds attract human attention more. The proposed ranking system of salient visual attention stimuli was achieved using an eye tracking procedure. This work provides a benchmark to specify the most salient stimulus with comprehensive information.
Collaborative Learning: Team Size and the Scientific Field as Influencers
Authors: Pacheco Dulce , Soares Luisa
Published: May 2018

Some individuals seem to intuitively collaborate better in teams, and some teams have repetitively superior results. Cooperative work is a growing need in all workplaces, and it has been thoroughly studied. However, literature has not yet clearly identified its predictors, as it does not present consistent results. Some authors report a reluctance in students to collaborate in teams, whereas others describe its huge advantages. This work intends to explore variables that might influence collaborative learning. We hypothesize that the team size and the scientific field of the students might affect team collaboration and team performance. In this study with Pre- and Post-test, team collaboration was measured using the Team Collaboration Evaluator (TCE) and team performance was assessed by the students’ perceived team effectiveness and by the final project grade given by the instructors. Analysis of a sample of 99 students, from both Computer Science and Psychology bachelor programs, indicates that larger teams show lower team collaboration, but higher team performance. Collected data confirm differences in the evolution of the perceived team collaboration, according to the students’ scientific field. Results are discussed considering the Team Collaboration Evaluator framework.

Tecnologías blandas en la gestión administrativa de las empresas constructoras mipymes
Authors: Montejo B. Andrés A.
Published: May 2018

Uno de los más graves problemas al interior de las Empresas Constructoras Mipymes (en adelante ECM) es la baja capacidad tecnológica tanto administrativa como de producción para competir exitosamente en un entorno altamente competitivo y globalizado, tal como se puede corroborar en el diagnóstico de CAMACOL sobre el Sector de la Construcción y en especial de las empresas MYPYMES (Cámara Colombiana de la Construcción [CAMACOL], 2010). El bajo nivel de inversión y desarrollo tecnológico a nivel organizativo y de producción ha llevado a las ECM, a una relación doblemente desigual de retraso respecto a los avances tecnológicos de los centros de producción y al predomino del mercado por las empresas de gran tamaño en el entorno nacional.

A pesar de la importancia estratégica y preponderancia del Sector de la Construcción en la economía nacional, (Cámara Colombiana de la Construcción [CAMACOL], 2010)2 y la baja participación de las ECM en el PIB Nacional, (informe DANE 2014), (Departamento Administrativo Nacional de Estadistica [DANE], 2013) 3 no se conocen estudios encaminados a indagar en esta problemática, que aborda los múltiples aspectos de la gerencia de las Mypimes y a profundizar en las razones específicas que afectan la productividad de estas organizaciones. La investigación busca obtener información sobre los efectos de la transferencia y aplicación de tecnologías blandas – software en los procesos del entorno organizacional de las empresas constructoras, mediante la indagación directa que permita caracterizar el fenómeno, las condiciones de aplicación y la medición de su efecto en la productividad del entorno organizativo.
La ética moral dialógica como artefacto perverso de gestión organizacional
Authors: Ruiz Medina Rodrigo Andrés
Published: May 2018

El presente documento, realiza una aproximación al dilema ético-moral que se visible en las organizaciones a la hora de tomar decisiones, dado que se presentan frecuentemente dos ópticas que se oponen mutuamente en las prácticas de gestión administrativa. Esta doble óptica, o dialógica ha sido abordada clásicamente desde un enfoque simplista, en un intento desmedido por anular la lógica subyacente. Sin embargo, enfoques sistémico-complejos proponen mecanismos de distensión para el abordaje problémico del fenómeno, haciendo que esa contradicción, sea confrontada con un enfoque ecologista, a través de la construcción de valores, a cambio de la inducción forzosa, y acompañada de un discurso consistente en vez de un doble discurso, y que a través de un proceso de construcción de comunicación moral, se permita la interacción y el acceso a diferentes niveles de verdad y de valores individuales o grupales con potencial de ser institucionalizados.

El problema del relativismo moral en las Organizaciones, se sugiere entonces, ser abordado desde una coherencia racional en procura de la estabilidad permanente, soportado en un sistema de valores y principios construidos, que permitan las decisiones reflexivas que favorezcan la construcción de un carácter a la hora de establecer metas y deliberar sobre ellas.

Finalmente, se resalta el aporte de la ética de mínimos, como posible camino para la minimización del totalitarismo moral y por ende, la posible coexistencia de una puralidad libre de temor e incertidumbre para quienes difieren de ella, que les permita compartir unos mínimos innegociables que operen al interior de las organizaciones.
