Authors: Clavero Blanco Cristina , Gordillo León Fernando , Pérez Nieto Miguel Ángel
Published: September 2020

El uso de las tecnologías tiene efectos positivos y negativos sobre los procesos cognitivos y afectivos, que en las últimas décadas han atraído la atención de los investigadores. En el presente estudio se investigó la relación entre la frecuencia del uso tecnológico y su influencia en el control inhibitorio y la capacidad atencional en adultos jóvenes, así como el papel jugado por la personalidad y el estado afectivo. Participaron 90 personas con edades comprendidas entre los 18 y 34 años, que realizaron las siguientes pruebas: Test de Stroop; Trail Making Test; Test Atencional d2; Cuestionario de Uso Problemático de las Nuevas Tecnologías; Eysenck Personality Questionnaire Revised-Abbreviated; y el Cuestionario de Afecto Positivo y Negativo. Los resultados mostraron relación significativa e inversa entre la frecuencia de uso de tecnologías como Internet y la Televisión, y las capacidades de inhibición y atención. Por otro lado, se observó una relación significativa y directa entre el uso de Internet y el Móvil, y los niveles de neuroticismo y afecto negativo. Estos resultados apuntan a un efecto negativo del exceso de uso de determinadas tecnologías sobre las capacidades cognitivas, que podría verse modulado por variables afectivas y de personalidad.

Authors: Martínez-Velázquez Eduardo Salvador , Conde Mota Leopoldo Gerardo , García-Aguilar Gregorio
Published: September 2020

La alexitimia se define como la dificultad de identificar, analizar y expresar las experiencias emocionales. Se ha reportado que las personas con alexitimia presentan dificultades a nivel social y en la percepción de distintos estímulos emocionales, sin embargo los resultados no han sido consistentes.

Objetivos: identificar el efecto de palabras socio-emocionales (insultos, elogios y neutros) en la percepción de personas con alto y bajo nivel de alexitimia por medio de un Stroop emocional.

Método: Participaron 44 estudiantes de nivel licenciatura y se conformaron dos grupos con base en la escala TAS-20, un grupo con alto puntaje GA (>61) y otro con bajo puntaje de alexitimia GB (<28). Se evaluó la percepción de estímulos socio-emocionales por medio del Stroop emocional, presentados en bloques por categoría. Además, se registraron los puntajes clínicos de depresión, ansiedad y fobia social.

Resultados: Se observó que el GA tuvo mayores tiempos de reacción ante las palabras socio-emocionales en comparación con el GB. Se presentó también un mayor puntaje en las escalas clínicas en el GA que el GB.

Conclusiones: Los resultados sugieren un sesgo atencional en personas con alexitimia ante palabras socio-emocionales. Asimismo, la puntuación obtenida de las escalas se mostró a favor de la relación entre la alexitimia y los síntomas clínicos.

Hybrid Filter for Enhancing Input Microphone-Based Discriminative Model
Authors: Hassan Hani S. , S. Jammila Harbi , Kodher Maisa'a Abid Ali
Published: September 2020

Voice denoising is the process of removing undesirable voices from the voice signal. Within the environmental noise and after the application of speech recognition system, the discriminative model finds it difficult to recognize the waveform of the voice signal. This is due to the fact that the environmental noise needs to use a suitable filter that does not affect the shaped waveform of the input microphone. This paper plans to build up a procedure for a discriminative model, using infinite impulse response filter (Butterworth filter) and local polynomial approximation (Savitzky-Golay) smoothing filter that is a polynomial regression on the signal values. Signal to noise ratio (SNR) was calculated after filtering to compare the results after and before adding the Savitzky-Golay smoothing filter. This procedure showed better results for the filtering of ambient noise and protecting a waveform from distortion, which makes the discriminative model more accurate when recognizing voice. Our procedure for preprocessing was developed and successfully implemented on a discriminative model by using MATLAB.

Penyebab Berkurangnya Anggota Koperasi: Studi Kasus Koperasi Perkebunan Sawit Perintis
Authors: Musthafa Danuar
Published: September 2020

The Koperasi Perkenuban Kelapa Sawit Perintis (KPS Perintis) is a forum for oil palm farmers to improve the quality of their crops. Joining a cooperative should make farmers feel comfortable and get various benefits. Besides that, oil palm farmer  cooperatives have a very important role and function as a medium of cooperation, teaching and learning, and increasing the yield of plantation production. However, in recent years, the number of the Perintis KPS members has decreased significantly. By using the Peter M. Blau Social Exchange Theory, this study aims to find the causes of farmers leaving the Peritis Cooperative membership by tracing the experiences of members when they are in groups resulting in social conditions that lead to the departure of members of the Perintis KPS. The method used is a qualitative method with in-depth interviews with research informants who are taken purposively. The results showed that there were five factors that led to the membership withdrawal of KPS Perintis members: First, the imbalance between sanctions and reward received by members. Second, the decline in the quality of Pioneer PPS. Third, the fear of members not being able to pay off bank loans for replanting. Fourth, internal family conflict. Fifth is avoidance of internal family members conflict.

Published: September 2020

Abstract : Remittances from migrants are one of the potentials that can be utilized by the village to improve welfare. Atar is one of the nagari which has a large number of guides in various cities in Indonesia. The problem raised in this study is to see how the pattern of use of remittances from migrants for Nagari Atar. The objectives of this research are; 1.) Describe the pattern of use of remittances from migrants at the household level and 2.) Describe the patterns of use of remittances from migrants for the development of Nagari Atar. As an analytical tool, the structuration theory proposed by Anthony Giddens is used. This study used a qualitative approach using in-depth interviews and observation as data collection tools. The results of this study indicate that the frequency of money transfers is uncertain and is sent only when there is a need. Meanwhile, the frequency of sending goods is sent during the new school year and Eid. Economic remittances are like money and goods, while social remittances are in the form of ideas and main ideas for village development. The pattern of using remittances at the family level is divided into the use of family consumptive remittances and the use of family productive remittances. The use of remittances at the village level is for the physical development of the village and the non-physical development of the village.
Experimental evaluation and tomographic characterization of polymer gel conformance treatment
Authors: Kalateh-Aghamohammadi Mina , Qajar Jafar , Esmaeilzadeh Feridun
Published: September 2020

Excessive water production from hydrocarbon reservoirs is considered as one of major problems, which has numerous economic and environmental consequences. Polymer-gel remediation has been widely used to reduce excessive water production during oil and gas recovery by plugging high permeability zones and improving conformance control. In this paper, we investigate the performance of a HPAM/PEI (water-soluble Hydrolyzed PolyAcrylaMide/PolyEthyleneImine) polymer-gel system for pore space blockage and permeability reduction for conformance control purpose. First, the gel optimum composition, resistance to salt and long life time are determined using bottle tests as a standard method to specify polymer-gel properties. Then the performance and stability of the optimized polymer-gel are tested experimentally using coreflood tests in sandpack core samples. The effects of different parameters such as gel concentration, initial permeability of the cores, and formation water salinity on the final permeability of the cores are examined. Finally, the gel flow-induced local porosity changes are studied in both a sandpack core and a real carbonate sample using grayscale intensity data provided from 3D Computed Tomography (CT) images in pre- and post-treatment states. The results show that the gel system has a good strength at the middle formation water salinity (in the range of typical sea water salinity). In addition, despite a higher performance in high permeability cores, the gel resistance to degradation in such porous media is reduced. The CT images reveal that the initial porosity distribution has a great influence on the performance of the gel to block the pore space.

Structural compressibility in 3d printed abrasion protection structures
Authors: Zedler Sarah Lysann
Published: September 2020

Abrasion protection in exposed areas is a common method of extending the life cycle of textile products. To achieve sufficient abrasion resistance, the textile products are usually coated or partially printed with hard products. But hard materials lead to stiffening and can have a negative effect on the haptics.
The aim of this study is the application of abrasion-resistant and compressible print patterns directly to textile substrates by 3D printing. The compressibility is achieved by the inner structure, which, in contrast to conventional coatings, is not 100 % filled. In the investigations, four thermoplastic materials were tested for their abrasion resistance and compressible properties. Fabrics made of cotton or polyester/cotton blends were used as textile substrates. Different approaches were taken to create the structures, some of which can only be realized using 3D printing technology.
The abrasion resistance of the substrates could be increased from 50 abrasion cycles to over 8,000 cycles with the help of the 3D printed patterns. It was possible to print 3D structures that could be compressed in thickness by up to 53 %. The combination of both properties, abrasion resistance and compressibility, can be used for new types of individual products with good wearing comfort and functionality that meet the requirements, especially in the areas of functional, protective and sports clothing.
Does CEO founder status protect against dismissal?
Authors: Bohdanowicz Leszek
Published: September 2020

Background: The article adds to the limited literature on CEO turnover in emerging market coun­tries and extends the existing research to a different institutional setting with a particular focus on listed companies in an increasingly important Polish business environment. It deals with the problem of CEO turnover in Polish listed companies.

Research purpose: Its main purpose is to scrutinize the impact of company performance and managerial ownership on CEO turnover. It focuses on finding the differences in the CEO turnover antecedences of founder CEO and professional CEO dismissal.

Methods: These relationships were tested using logistic regression. The sample consists of Pol­ish public companies listed on the Main Market of the Warsaw Stock Exchange, encompassing 11 years from 2008 to 2018. The final sample embraces an unbalanced panel sample of 489 com­panies and 3,763 company-year observations.

Conclusions: The analysis throughout the sample showed that the relationship between firm per­formance and CEO turnover is negative. Thus, deterioration of firm performance increases the frequency of changes in CEO. However, after conducting an in-depth study, it was found that this relationship is statistically significant only when professional managers manage the companies. The relationship between managerial ownership and turnover was also significant and negative in the whole sample. Still, there were also differences between changes in the CEO position, depend­ing on whether it was the company’s founder or a professional manager. In the case of founder CEOs, this relationship was even significant and positive, as opposed to professional managers. This was the same as in the whole sample.
Decomposition of unemployment rates in Poland according to voivodeships in the years 2013–2018
Authors: Kucharski Leszek
Published: September 2020

Background: Unemployment is a phenomenon that occurs in all market economies, although with different intensity. Its rate is influenced by many factors related to labour demand and labour supply, as well as by structural mismatches between the two sides of the labour market, its effec­tiveness, the type of macroeconomic policy, and the labour market institutions.

Research purpose: The aim of the research is to determine the influence of labour supply and la­bour demand factors on changes in unemployment rates in Polish voivodeships from 2013 to 2018.

Methods: The unemployment rates for Poland and its voivodeships are decomposed using the aggregate data on unemployment rates, employment rates, and economic activity rates published by the GUS and the formula proposed by Elsby, Hobijn, and Sahin (2010).

Conclusions: The research results point to rising employment rates as the key factor driving the fall of unemployment rates between 2013 and 2018 in most Polish voivodeships. The exceptions are the Lubelskie and Świętokrzyskie voivodeships, where unemployment rate decreases were mainly caused by outflows from employment to inactivity. The downward trends in unemploy­ment rates in Poland and some of its voivodeships in the years 2015–2018 were facilitated by processes taking place on the supply side of the labour market.
Fulfilling the Right to Food for South Africa: Justice, Security, Sovereignty and the Politics of Malnutrition
Authors: Moyo Busiso Helard , Thow Anne Marie Thompson
Published: September 2020

Despite South Africa’s celebrated constitutional commitments that have expanded and deepened South Africa’s commitment to realise socio-economic rights, limited progress in implementing right to food policies stands to compromise the country’s developmental path. If not a deliberate policy choice, the persistence of hunger, food insecurity and malnutrition in all its forms is a deep policy failure.  Food system transformation in South Africa requires addressing wider issues of who controls the food supply, thus influencing the food chain and the food choices of the individual and communities. This paper examines three global rights-based paradigms – ‘food justice’, ‘food security’ and ‘food sovereignty’ – that inform activism on the right to food globally and their relevance to food system change in South Africa; for both fulfilling the right to food and addressing all forms of malnutrition. We conclude that the emerging concept of food sovereignty has important yet largely unexplored possibilities for democratically managing food systems for better health outcomes.
Why make fake breastmilk?
Authors: Kent George
Published: September 2020

There are efforts underway to make “breastmilk” called Biomilq through cell culture, “to produce cultured human breastmilk using patent-pending technology in order to offer families a more nutritious and more sustainable option for feeding babies.” However, Biomilq advocates have not explained their claims that the product would be better for infants’ health or for the environment. Their claim that the product would be breastmilk and not a breastmilk substitute is not convincing. They argue that until now women who cannot or choose not to breastfeed have no alternative but to feed with infant formula, but they ignore options such as mothers expressing their own milk or using wet-nurses. They do not mention the possibility of feeding with pasteurized human milk from other women, obtained through a human milk bank. The prospects for Biomilq do not look promising.
EARPC – Energy Aware Routing Protocol for Cooperative MIMO Scheme in WSNs
Authors: Reddy Kummathi Chenna , Devanagavi Geetha D. , M. N. Thippeswamy
Published: September 2020

Wireless sensor networks are typically operated on batteries. Therefore, in order to prolong network lifetime, an energy eﬃcient routing algorithm is required. In this paper, an energy-aware routing protocol for the co-operative MIMO scheme in WSNs (EARPC) is presented. It is based on an improved cluster head selection method that considers the remaining energy level of a node and recent energy consumption of all nodes. This means that sensor nodes with lower energy levels are less likely to be chosen as cluster heads. Next, based on the cooperative node selection in each cluster, a virtual MIMO array is created, reducing uneven distribution of clusters. Simulation results show that the proposed routing protocol may reduce energy consumption and improve network lifetime compared with the LEACH protocol

Authors: Caturono Yahya
Published: September 2020

Konserto trompet haydn ini merupakan konserto trompet pertama yang diciptakan oleh haydn. Konserto ini diciptakan untuk trompet berkunci dalam Es dan ditujukan untuk temannya pemain trompet yang bernama Anton weidinger, pemain trompet di istana Wina. Trompet berkunci adalah trompet yang dapat mengeluarkan nada- nada kromatis, trompet berkunci diciptakan oleh Reidl, dan merupakan instrumen musik yang menjadi pelopor pada tipenya dikarenakan sebelumnya tidak menggunakan kunci. penulis tertarik meneliti tentang teknik variasi melodi ini dikarenakan keistimewaan konserto yang diciptakan oleh haydn ini untuk temanya dan lebih menonjolkan nada nada kromatik. Namun sebelum meneliti tentang variasi melodi, peneliti menguraikan struktur lagu untuk mempermudah dalam menjabarkan mengenai variasi melodi.

The purpose of this study was to analyze the residents’ perception towards the Chinese cultural attraction as an icon of cultural heritage tourism in Manado city. Manado is a predominantly Christian community and dominated by indigenous Minahasa tribes. But, now the city is populated by various inhabitants such as Sangir, Gorontalo, Maluku, and even foreign immigrants such as China and Arab migrating since the Dutch colonial era. Of the various communities that exist, practically only the Chinese community that still maintains its rituals amid strong advances in the tourism industry, this cultural practice can become an icon for cultural tourism. However, can the cultural ritual be accepted as an icon of Manado cultural tourism? This research was in the form of a descriptive qualitative approach. The instruments of data collection were questionnaires and field observations. Questionnaires were distributed to 325 respondents spread in Manado. Empirical results showed that every ritual attraction of Chinese Culture had always been awaited and an interesting spectacle for the people of Manado since the people of Chinese descent domiciled in Manado City. These findings could also provide recommendations for policymakers in setting annual tourist agendas as well as providing legal certainty for this region of Chinatown with various attractions as a cultural heritage area.

This study aimed at reporting differences in terms of the university students’ TOEFL self-efficacy in the test skill and the English skills tested in TOEFL namely listening, structure, and reading. In conducting the study, the explanatory sequential mixed method was used as the study design, where the quantitative data from the survey was conducted first followed by the follow-up interview as the qualitative data. To collect the data in this study, a specifically designed self-efficacy questionnaire of TOEFL was distributed to the total sample of 200 university students across different disciplines from Syiah Kuala University and the University of Serambi Mekkah. The interview was then conducted with 3 selected students to have a deeper understanding of the study result. In terms of the data analysis, one-way ANOVA and t-test were used to describe the quantitative data, while the qualitative data was described and elaborated in words with detailed explanations. The result showed that there was a significant difference among the test skill and the English skills in TOEFL, where F= 13.61 (3, 796), p<0.05. The result also revealed that within the gender, only reading skill had a significant difference, where t198= -2.003, p <. 005, and within the language course participation, all the test skills and TOEFL skills were significantly different as the p-value of each skill was smaller than .005 (p< .005).

На примере 2-фенилпиридина (phpy) исследовано влияние объемного фенильного замес­тителя на формирование и устойчивость пивалатных комплексов 3d-переходных металлов. Квантово-химическими расчетами в приближении B3LYP/Def2-TZVP оптимизированы биядерные молекулы комплексов [M2(μ-piv)4L2], где M = Сo, Ni, Cu, piv = Me3CCO2– и L = 2,3-лутидин (lut), для которого известны анализируемые соединения, phpy и 7,8-бензохинолин (bquin). Вычисленные энергетические характеристики указывают на значительную устойчивость комплексов с lut и дают основания ожидать получения аналогичных соединений с phpy. Успешный синтез комплекса [Cu2(piv)4(phpy)2] (3) подтвердил корректность теоретических расчетов. Компьютерное изучение биядерных координационных соединений с bquin показало принципиальную возможность их формирования, однако меньшая энергия стабилизации таких структур по сравнению с комплексами сравнения ([M2(piv)4(DMF)2]) свидетельствует о сложности препаративного выделения. Выделены и определены молекулярные структуры новых молекулярных комплексов [Ni9(OH)6(piv)12(Hpiv)2(phpy)]·C6H6 (2) и [Li2Co2(piv)6(рhpy)2] (4).
Long-term Deflections of Hybrid GFRP/Steel Reinforced Concrete Beams under Sustained Loads

Published: September 2020

One of the solutions to improve the flexural behavior of Glass fiber reinforced polymer (GFRP) reinforced concrete (RC) beams is the addition of tensile longitudinal steel reinforcement. The numerous studies to date on hybrid GFRP/steel RC elements have mainly focused on the static and short-term responses, very little work has been done regarding the long-term performance. This paper presents experimental results of time-dependent deflections of cracked GFRP and hybrid GFRP/steel RC beams during a 330-day-period in natural climate conditions. Three hybrid GFRP/steel and one GFRP RC beams with dimensions 100×200×2000 mm were tested in four-point bending. Different steel reinforcement ratios were used to evaluate the effect of the steel reinforcement on the long-term behavior of the beams. Experimental results show that the immediate deflections are inversely proportional to the additional steel reinforcement. With the same initial instantaneous deflection, the total deflection increases when increasing the steel reinforcement ratio. Also, temperature (T) and relative humidity (RH) significantly affect the long-term deflection of the tested beams. The measured long-term deflections were found to be in good agreement with the theoretical values calculated from the proposed method. However, there was an overestimation when using ACI 440.1R-15 or CSA-S806-12 procedures.

Abstract:

Aim: This paper presents a waste stream exploratory study with the purpose of identifying opportunity gaps to reduce environmental and health risks within the household waste stream in a small rural population in Northwestern Mexico by following the waste management hierarchy.

Design / Research methods: The study consisted of three phases. Firstly, a one-stage cluster sampling was conducted to characterize the household waste in this rural population. A cluster in this study was a block. There were 54 clusters, but only 40 with occupied houses. The clusters were selected by simple random sampling. During the second phase of this study, a survey was conducted to examine the waste management practices of the residents of sampled houses. Considering that 51 were the habited houses in the sampled clusters, a simple random sampling for finite populations was selected.  Finally, a quadrat sampling method was conducted. The total area of the municipal landfill site was divided into black and white quadrats. The white color was represented by tails while the black color was represented by heads. The color of the sampled quadrats was selected after 50 flip virtual coins for true randomness.

Conclusions/findings: Findings in this study indicate the willingness of the inhabitants in this rural location to participate in source reduction initiatives. Findings also showed that organic waste was the predominant material in the household waste composition. Therefore, there are opportunities to enhance composting at home or even implement a community composting program. The riskier situations revealed by this study were observed at the landfill site where air emissions and leachate occurred.

Originality/value of the article: Based on the waste stream analysis, there are some opportunities to reduce the environmental and health risks in a small rural zone in Northwestern Mexico. In this regard, this study can serve as an example to analyze and compare sustainable opportunities in other rural zones around the world.

Keywords: Waste management, Rural Development, Landfill, Waste Stream Analysis.
