Comportamiento de las entidades integrantes del sistema financiero costarricense durante la crisis económica mundial de 2008. Costa Rican financial system entities behavoir during 2008 world economic crisis.
Authors: Rojas Blanco Hernán
Published: December 2017

Resumen 

Uno de los fenómenos financieros de mayor importancia e impacto mundial de las últimas décadas fue la crisis económica mundial de 2008. Fenómeno que, a pesar de tener un origen territorialmente focalizado, tuvo un impacto global. El presente artículo analiza el comportamiento del sistema financiero costarricense en medio del fenómeno económico citado. Para explicar dicha conducta, es de suma importancia ahondar en el actuar financiero y contable de cada una de las entidades que lo componen, con el objetivo de determinar su proceder y evolución en los períodos de pre-crisis, crisis y post-crisis. El análisis financiero propuesto se desarrolló mediante una metodología basada en el análisis de datos a nivel granular (extracción, procesamiento y visualización), agrupados posteriormente mediante la generación y caracterización de clúster. La implementación de este tipo de metodología posibilitó la determinación del período real de la vigencia de los efectos de la crisis en el sistema financiero, las estrategias de mitigación implementadas contra sus efectos y comportamiento cíclico mantenido por las entidades financieras en observación.

 

Abstract 

The 2008 world economic crisis became one of the most important and globally impacting events of the last decades. Despite having a specific territorial origin, this phenomenon had a major global impact. The present article analyzes the performance of one of the main economic components, which is the financial system, particularly the Costa Rican financial system, throughout the aforementioned economic phenomenon. To explain such performance, it is important to go into detail on the financial and accounting procedures of each of its entities, in order to determine its behaviors and evolution before, after, and mainly, throughout the duration of this financial crisis. The proposed financial analysis was developed following an approach based on data analysis at a granular level (extractions, processing, and visualization), subsequently grouped through a cluster generation and characterization. The implementation of this methodology allowed to determine the actual duration of the effects of such financial crisis, and the mitigation strategies that were implemented against its effects and cyclical behavior (with predictive characteristics) of the overall observed financial entities.

Resumen 

La co-creación de valor ha sido ampliamente desarrollada como un nuevo paradigma en la gestión de la innovación, permitiendo a empresas y clientes crear valor a través de las interacciones entre los diferentes stakeholders. Este enfoque ha sido principalmente abordado en el ámbito empresarial, no siendo aplicado en profundidad en el contexto universitario. Es por esta razón que el principal aporte del presente trabajo es profundizar, mediante una revisión de la literatura, en el concepto de co-creación de valor en Instituciones de Educación Superior centrándose específicamente en la interacción entre el estudiante y la universidad. De igual forma, se estudian las relaciones entre los diferentes factores clave involucrados: participación comunicativa, confianza, satisfacción y lealtad. El objetivo del estudio es identificar hasta qué punto dichos factores son relevantes en un modelo de co-creación de valor en entornos de educación superior. Como resultado, se identifican 111 documentos relevantes relacionados con el tema abordado. Esta perspectiva corresponde a las nuevas tendencias de enseñanza-aprendizaje en la universidad, en la cual los profesores dejan de ser el centro del proceso y pasan a ser solo una parte de este. Este cambio convierte a los estudiantes en la columna vertebral del proceso de co-creación de valor; proporcionando esta investigación un marco conceptual que respalda futuros estudios de co-creación en las instituciones universitarias.

 

Abstract 

Value co-creation has been broadly developed as a new paradigm in management innovation. It allows companies and customers to create value through interaction. However, it has not been examined in depth in Higher Education contexts as a type of service industry. The present paper clarifies value co-creation in Higher Education Institutions, analysing the relationships between key factors affecting it: communicative participation, trust, satisfaction and loyalty. A literature review was conducted, resulting in 84 relevant papers dealing with the studied topic. The study was focused on the micro level, and, specifically, it analyses the relation between students and Higher Education institutions as main actors of value co-creation within this context. This perspective corresponds to the new trends in university teaching-learning framework, where professors are no longer the heart of the process, to become just a part of it. This shift makes students the backbone of the value co-creation process. This study provides, among other things, a conceptual framework to endorse further works on value co-creation in Higher Education institutions.
Smoking Urges During Treatment and Long-Term Cessation among Low-Income African Americans
Authors: Webb Hooper Monica , Dietz Noella A. , Wilson Joseph C.
Published: December 2017

Objective: The urge to smoke is a predictor of smoking relapse. Little research has focused on the impact of acute urges during treatment among African Americans. This study examined the relationship between smoking urges and long-term abstinence among treatment seekers. 

Design: Longitudinal prospective investigation. Urges to smoke were assessed at the initial (session 1) and final (session 8) sessions among adult smokers (N=308) enrolled in a 4-week group intervention trial. Nicotine patch use was assessed over 30 days. 

Main Outcome Measures: Biochemically verified 7-day point prevalence abstinence (7-day ppa) was assessed immediately postintervention, and at 3-, 6-, and 12-month follow-ups. Hierarchical logistic regressions tested associations between session 1 and session 8 urges and 7-day ppa at each smoking status assessment. 

Results: There was a significant overall decrease in smoking urges (M=29, SD=15 at session 1; M=17, SD=11 at session 8). After controlling for covariates, urges to smoke at session 1 were unrelated to 7-day ppa at any of the assessment points. However, session 8 urges were inversely associated with 7-day ppa post-intervention (AOR=.94, CI:.92-.97), at 3-months (AOR=.93, CI: .89-.97), 6-months (AOR=.93, CI: .90-.97), and 12-months (AOR=.96, CI: .96-.99). Nicotine patch use was positively associated with 7-day ppa at each assessment. 

Conclusions: The most robust predictors of abstinence through 12-months postintervention were decreased urges over the 4-week, 8-session group intervention and the frequency of nicotine patch use. Interventions aimed at addressing the needs of African American smokers should address urges and encourage nicotine replacement adherence to increase abstinence rates.

Engaging African Americans in Research: The Recruiter’s Perspective
Authors: Barrett Nadine J. , Ingraham Kearston L. , Hawkins Tracey Vann , Moorman Patricia G.
Published: December 2017

Purpose: To examine barriers recruiters encounter when enrolling African American study participants, identify motivating factors to increase research participation, and provide recommendations to facilitate successful minority recruitment. 

Background: Recruiters are often the first point of contact between the research study and potential African American participants. While challenges in enrolling African Americans into clinical and epidemiologic research has been reported in numerous studies the non-physician recruiter’s role as a determinant of overall participation rates has received minimal attention. 

Methods: We conducted four 90-minute teleconference focus groups with 18 recruiters experienced in enrolling African Americans for clinical and epidemiologic studies at five academic/medical institutions. Participants represented diverse racial and ethnic backgrounds and were asked to reflect on barriers preventing African Americans from participating in research studies, factors that motivated participation, and recommendations to increase participation of African Americans in research. Multi-coder and thematic data analysis was implemented using the Braun and Clarke method. 

Results: Prominent concerns in recruitment of African Americans in research include fear and mistrust and inflexible research protocols. The participants suggest that improved recruitment could be achieved through cross-cultural and skillset building training opportunities for recruiters, greater community engagement among researchers, and better engagement with clinic staff and research teams.

Dynamics of Trafficking in Human Beings and the Role of the Social Worker (Albanian Case)
Authors: Ervin Muco
Published: December 2017

The phenomena of Human Trafficking constitutes a violation of human rights, by restricting the freedom and putting in danger the lives of individuals, communities, and states. It positions individuals on slavery conditions and as a consequence victimizes them. Meanwhile, profits generated by human trafficking, the low risk and cost of engaging in this criminal activity, makes it very attractive for individuals, criminals networks, and the state as well. This causes negative consequences not only on individuals live but also on the economy and the political stability of a country. It harms social relation, brings a sense of fear and unsafety, and decreases the social trust among members of the community and state institutions. Moreover, THB has a negative impact on the economy by enabling individuals, organized crime, corporates, and states to maximise their profits by exploiting people. To succeed in the fight against THB and the reintegration process as well, we must recognize the factors that motivate and support it and actors involved in this operations (individuals, groups, organizations, and institutions). In this context, the role of the social worker is critical to understanding the phenomena and its consequences at different levels: micro, mezzo, and macro.

La evaluación fonoaudiológica de la respiración es una herramienta indispensable para el profesional de la salud ya que permite conocer qué dificultades tiene la persona al respirar. Este protocolo en la actualidad se realiza de manera manual con ayuda de pocos marcadores, los cuales no permiten caracterizar la postura corporal, relacionada con distancias, ángulos y posiciones de manera general y segura. Este artículo presenta una novedosa alternativa en el desarrollo de un sistema para mediciones automáticas de variables antropométricas, que intervienen en la evaluación fonoaudiológica de la respiración, usando visión artificial. Se tomaron variables en los 4 planos: frontal, posterior, sagital izquierdo y sagital derecho; igualmente, se incluyeron 32 marcadores para obtener 35 variables antropométricas. El principio de funcionamiento del algoritmo automático para el reconocimiento de variables antropométricas, se probó con dos pacientes, logrando un porcentaje de error general del sistema de 2,81%. Es importante resaltar que este desarrollo permitirá al especialista apoyarse en una herramienta digital para lograr medidas más precisas, mejorando la exactitud y la precisión en el diagnóstico.
Can Human Rights and Indigenous Spirituality Prevail over State-Corporatism? A Narrative of Ecological and Cultural Rights Violation from East Kalimantan, Indonesia
Authors: Buana Mirza Satria
Published: December 2017

This article examines both theoretical and empirical discussion on strategies to overcome state-corporatism and developmentalism practices in East Kalimantan, Indonesia. State-corporatism is the term used to describe a political condition when a state has a strong linkage to organized groups. Developmentalism is an over-arching concept to describe a strong tendency of a state to maximize economics growths through investment, while disregarding people’s fundamental rights. East Kalimantan Province is selected because it is highly known as one of the enournous amount of natural resources found within among other provinces in Indonesia. However, the richness of this province has become a curse of its people due to massive destructions of natural resources. This paper seeks to analyse in what way human rights’ principles and indigenous spirituality can lessen the negative effects of ‘development’ projects sustained by state-corporatism. This article contemplates what strategies that can be executed to diminish state-corporatism effects in East Kalimantan, particularly in two important districts: Regency of Kutai Kartanegara and Bontang Municipality. This article argues that the indigenous spirituality is a key to battle state-corporatism’s influences. Indigenous spirituality as forum internum is still a potential tool of advocacy. By capitalizing the role of shamans, indigenous peoples might still have opportunities to reclaim and defend their cultural rights.

Estos resultados se discuten a la luz de teoría e investigaciones previas.
Fault Diagnosis of Induction Machines in Transient Regime Using Current Sensors with an Optimized Slepian Window
Authors: Burriel-Valencia Jordi , Puche-Panadero Ruben , Martinez-Roman Javier , Sapena-Bañó Angel , Pineda-Sanchez Manuel
Published: December 2017

The aim of this paper is to introduce a new methodology for the fault diagnosis of induction machines working in transient regime, when time-frequency analysis tools are used. The proposed method relies on the use of the optimized Slepian window for performing the short time Fourier transform (STFT) of the stator current signal. It is shown that for a given sequence length of finite duration the Slepian window has the maximum concentration of energy, greater than can be reached with a gated Gaussian window, which is usually used as analysis window. In this paper the use and optimization of the Slepian window for fault diagnosis of induction machines is theoretically introduced and experimentally validated through the test of a 3.15 MW induction motor with broken bars during the start-up transient. The theoretical analysis and the experimental results show that the use of the Slepian window can highlight the fault components in the current's spectrogram with a significant reduction of the required computational resources.

Core Ideas

Efficient use of crop residues can improve circular economy in agro‐ecosystems.

Amount of stover to the field explained the variation in root length density and root dry weight density in double cropping of winter wheat and summer maize.

Returning stover increased the yield of summer maize.

Root characteristics and the yield of summer maize improved by returning stover.

A 5‐yr experiment was conducted to explore the effects of returning various amounts of stover to the field on root characteristics and yield in a wheat (Triticum aestivum L.) and maize (Zea mays L.) double‐cropping system. The experiment was designed as a randomized block design with three replications for three treatments: based on all stalks of winter wheat returned to the field (i) all summer maize stalks were mechanically pulverized and returned to the field (SR); (ii) half of the summer maize stalks were mechanically pulverized and returned to the field (1/2 SR); and (iii) all summer maize stalks were fully removed (CK). Results indicated that, in the SR treatment, root fresh weight (RFW) and root dry weight (RDW) were 19.4 and 18.5% higher, respectively, compared with the CK treatment. Root length density (RLD), root surface area density (RSAD) were 13.7 and 29.4% higher in the SR treatment, compared with the CK treatment. The yield of summer maize was 15.1 and 17.1% higher in the SR and 1/2 SR treatments, respectively, compared with the CK treatment. Furthermore, RLD, RSAD, root dry weight density (RDWD), and root length in the 1/2 SR treatment were significantly higher than those in the SR treatment. These results indicated that moderate amounts of straw returned to the field had the greatest effect on root growth and development of maize. This work provides a theoretical basis for optimizing crop yield and the use of straw resources.
Dryland Corn and Grain Sorghum Yield Response to Available Soil Water at Planting
Authors: Schlegel Alan J. , Lamm Freddie R. , Assefa Yared , Stone Loyd R.
Published: December 2017

Core Ideas

Yield gains from available soil water at planting decreased as in‐season precipitation increased.

Corn yield gain 27 to 33 kg ha–1 (mm available soil water at planting)–1 at in‐season precipitation of 196 to 215 mm.

Corn yield gain 9 to 25 kg ha–1 (mm available soil water at planting)–1 as in‐season precipitation increased to 288 to 354 mm.

Sorghum yield gain 12 to 22 kg ha–1 (mm available soil water at planting)–1 at in‐season precipitation of 163 to 281 mm.

Sorghum yield gain 0 to 6 kg ha–1 (mm available soil water at planting)–1 at in‐season precipitation of 315 to 382 mm.

Most dryland soil and crop management systems are geared toward improving amount and use of available soil water (ASW) at planting (ASWP) and in‐season precipitation (ISP). The relationship between ASWP and yield has seldom been a singular research focus. The objective of this study was to investigate the effect of different levels of ASWP on yield and water productivity of dryland corn (Zea mays L.) and grain sorghum [Sorghum bicolor (L.) Moench]. The study was conducted at two locations, Tribune and Colby, KS, for 3 yr, 2012 to 2014. Four different levels of ASWP were established by applying irrigation prior to planting (0, 38, 76, or 114 mm). Corn and sorghum yield increased in response to increased ASWP but yield gains per millimeter of ASWP decreased as ISP increased. Corn yield gain was in the range of 27 to 33 kg ha−1 (mm ASWP) −1 when ISP was in the range of 196 to 215 mm and yield gain decreased to 9 to 25 kg ha−1 (mm ASWP)−1 when ISP increased to 288 to 354 mm. Similarly, grain sorghum yield response to ASWP decreased from 12 to 22 kg ha−1 to 0 to 6 kg ha−1 per millimeter ASWP when ISP increased from 163 to 281 mm to a range of 315 to 382 mm. We concluded that dryland corn and grain sorghum yield increased with increased level of ASWP and a significant contribution of ASWP to yield production is realized when ISP is low.

Published: December 2017

The article 4 clause 2 in the Act Number 1 Year 1974, mentioned that discrimination against women (wife) potentially in increasing the divorce rates. It can be minimized by creating a gender-based mindset, that will be the object of this research. This research will use qualitative methods with normative juridical approach. This research found that: firstly, that the Act Number 1 Year 1974 and its derivative laws such as Compilation of Islamic Law (KHI), has not reach yet the Pancasila values and also justice and humanity as the main mission of law. Secondly, the political configuration in the drafting of laws and “black and white” in understanding of religious texts are contribute to creating injustice. Thirdly, the justice is one of the goals of the law, so discrimination must be eliminated. This research provides a recommendation that polygamy in article 4 clause 2 in the Act Number 1 Year 1974 must be removed, and become the principle of monogamy absolutely.

[]

Diskriminasi terhadap perempuan (Isteri), sebagaimana tertuang pada Pasal 4 ayat 2 UU No. 1 Tahun 1974, berpotensi menciptakan tingginya angka perceraian. Meminimalisasi hal tersebut dengan membangun pemikiran berbasis keadilan gender merupakan tujuan dalam penelitian ini. Adapun metode yang dipilih adalah kualitatif dengan pendekatan yuridis-normatif. Hasil penelitian yang ditemukan; Pertama, bahwa UU No. 1 Tahun 1974 beserta perundang-undangan turunannya seperti KHI, masih jauh dari nilai-nilai Pancasila dan misi utama hukum; yaitu nilai keadilan dan kemanusiaan. Kedua, konfigurasi politik dalam produksi UU Perkawinan dan pemahaman teks agama yang “hitam-putih” adalah kontributor terciptanya ketidakadilan. Ketiga, salah satu tujuan hukum adalah keadilan, maka bentuk-bentuk diskriminasi harus dihapuskan. Artikel ini merekomendasikan penghapusan poligami dalam pasal 4 ayat 2 UU No.1 Tahun 1974, dan menjadikan monogami bersifat mutlak.
Application of low frequency vibration to degassing of highly viscous shear-thinning fluids
Authors: Zhan Xiaobin , Shen Baojun , He Yu , Sun Zhibin , Li Xiwen
Published: December 2017

The removal of unwanted gas bubbles is an important operation in many processes. In this paper, the mechanism of the degassing of highly viscous fluids by low-frequency vibration is studied numerically using the computational fluid dynamics (CFD). The effects of vibration frequency and amplitude on the degassing rate are investigated. The results show that the superimposed mechanical vibration largely affects the degassing rate of shear-thinning fluids but exerts no effect on that of Newtonian fluids. The de-gassing rate of shear-thinning fluids depends on the vibration frequency and amplitude. What’s more, low-frequency and small-amplitude vibration is particularly useful in re-moving gas bubbles from viscous shear-thinning fluids, however, high-frequency or large-amplitude vibration may intensify air entrapment and brings new gas bubbles into fluids.
A parametric study on the dynamic response of reciprocating compressor with a revolute clearance joints
Authors: Cheng Shouguo
Published: December 2017

Due to the friction and manufacturing and assembly errors, the clearance of revolution joints is unavoidable. When the clearance value increases to a certain value, the influence of clearance on the performance of the equipment could not be ignored. In this paper, the contact collision model is used to describe the effect of clearance. The model of reciprocating compressor is simplified properly, and the influence of revolution joint clearance on the system is studied by contact impact function. The influence of parameters on the acceleration of piston is studied by changing the size, position of clearance and velocity of crankshaft. The Lyapunov exponent of crosshead acceleration under the condition of load and no load are compared, which lays the foundation for studying the vibration of reciprocating compressor caused by clearance.

Computational fluid dynamics analysis of a high-throughput viscous heater to process feces and a fecal simulant using temperature and shear rate-dependent viscosity model
Authors: German C. L. , Podichetty J. T. , Muzhingi A. , Makununika B. , Smay J. , Foutch G. L.
Published: December 2017

Open defecation and poor fecal management facilitates the spread of disease. Viscous heating can pasteurize fecal sludge by creating a high shear field in the annular gap between a stationary, cylindrical outer shell and a rotating inner core. As sludge flows axially through the annular gap, thorough mixing and frictional heating eliminate cool spots where microbes may survive. A viscous heater (VH) compares favorably to a conventional heat exchanger, where cool slugs may occur. Computational fluid dynamics (CFD) was used to determine the effects of geometry and fluid rheology on VH performance over a range of conditions. A shear-rate and temperature-dependent rheological model was developed from experimental data, using a sludge simulant. CFD of an existing VH used the model to improve the original naïve design by including temperature and shear rate-dependent viscosity. CFD results were compared to experimental data at 132 and 200 L/hr to predict design and operating conditions for 1,000 L/hr. Subsequent experimentation with fecal sludge indicated that the CFD approach was valid for design and operation.
Evaluation of microbial fuel cell (MFC) for bioelectricity generation and pollutants removal from sugar beet processing wastewater (SBPW)
Authors: Rahman Atikur , Borhan Md Saidul , Rahman Shafiqur
Published: December 2017

Bioelectricity generation from biodegradable compounds using microbial fuel cells (MFCs) offers an opportunity for simultaneous wastewater treatment. This study evaluated the synergy of electricity generation by the MFC while reducing pollutants from sugar beet processing wastewater (SBPW). A simple dual-chamber MFC was constructed with inexpensive materials without using catalysts. Raw SBPW was diluted to several concentrations (chemical oxygen demand (COD) of 505 to 5,750 mg L−1) and fed as batch-mode into the MFC without further modification. A power density of 14.9 mW m−2 as power output was observed at a COD concentration of 2,565 mg L−1. Coulombic efficiency varied from 6.21% to 0.73%, indicating diffusion of oxygen through the cation exchange membrane and other methanogenesis and fermentation processes occurring in the anode chamber. In this study, >97% of the COD and up to 100% of the total suspended solids removals were observed from MFC-treated SBPW. Scanning electron microscopy of anode indicated that a diverse community of microbial consortia was active for electricity generation and wastewater treatment. This study demonstrated that SBPW can be used as a substrate in the MFC to generate electricity as well as to treat for pollutant removal.

Da reflexão sobreveio o potencial das Comunidades de Prática no processo de construção da identidade profissional dos estagiários, que aqui encontram um espaço de partilha e de reflexão que lhes permite construir e reconstruir conceções, pelo assumir gradual de papéis potencialmente emancipatórios. Já as limitações incorrem das relações estabelecidas no seio das Comunidades de Prática quando estas se estruturam com base numa hierarquia excessiva e unidirecional.Palavras-chave: Comunidade de Prática; Identidade profissional; Estágio; Estudantes estagiários ABSTRACTTeacher training has experienced substantive changes with respect to its composition and organization. Given that learning is socially and culturally situated, this conceptual reflection text aimed to re-evaluate the formative value of the Communities of Practice in the construction of the professional identity of future teachers within practicum, as well as recognize the constraints that Communities of Practice may entail. From the reflection, it can be emphasised the potential of the Communities of Practice in the process of building the professional identity of the preservice teachers, since they find a space of sharing and reflection that allows them to construct and reconstruct conceptions, by gradually taking on potentially emancipatory roles. Limitations, on the other hand, lie in the relations established within the Communities of Practice when they are structured on the basis of an excessive and unidirectional hierarchy.Keywords: Community of Practice; Professional identity; Practicum; Preservice teachers
Integrated Models of Care for People Living with Hepatitis C Virus and a Substance Use Disorder: Protocol for a Systematic Review (Preprint)
Authors: Ti Lianping , Parent Stephanie , Socías María Eugenia
Published: December 2017

BACKGROUND

People living with a substance use disorder (SUD) are a key population within the hepatitis C virus (HCV) epidemic. While integrated and community-based models of care have shown positive outcomes among this population, the literature has been primarily focused on the HIV context. This paper outlines a systematic review protocol on the impact of various integrated models of care, which includes HCV and SUD services, on various treatment, and health-related outcomes among this population.

OBJECTIVE

The objective of this review is to determine the impact of integrated models of care on HCV and addiction treatment and health-related outcomes for adults living with HCV and an SUD.

METHODS

We will search 5 databases, article reference lists, and abstracts from relevant conferences that investigate the impact of integrated models of care on treatment and health-related outcomes among people living with HCV and an SUD. Database searches will be conducted and titles, abstracts, and the full-text of the relevant studies will be independently reviewed in separate stages. The methodological quality of included studies will be assessed using a validated tool. Data from included articles will be extracted using a standardized form and synthesized in a narrative account.

RESULTS

For this project, we have received funding from the Canadian Institute of Health Research. To date, we have completed the search strategy, reviewed the titles, abstracts, and full-texts. Grading the selected studies and qualitative synthesis of the results are currently under way, and we expect the final results to be submitted for publication in the fall of 2018.

CONCLUSIONS

The systematic review will describe different integrated models of care that could be effective in improving the health and well-being of people living with HCV and an SUD. Results of this review could also identify quality improvement strategies to minimize the health and cost burden imposed on patients, healthcare professionals, and the healthcare system.

BACKGROUND

To address the limitations of the retrospective self-reports of activity, such as its susceptibility to recall bias, researchers have shifted toward collecting real-time activity data on mobile devices via ecological momentary assessment (EMA). Although EMA is becoming increasingly common, it is not known how EMA self-reports of physical activity and sedentary behaviors relate to the objective measures of activity or whether there are factors that may influence the strength of association between these two measures. Understanding the relationship between EMA and accelerometry can optimize future instrument selection in studies assessing activity and health outcomes.

OBJECTIVE

The aim of this study was to examine the associations between EMA-reported sports or exercise using the accelerometer-measured moderate-to-vigorous physical activity (MVPA) and EMA-reported TV, videos, or video games with the accelerometer-measured sedentary time (ST) in children during matched 2-h windows and test potential moderators.

METHODS

Children (N=192; mean age 9.6 years; 94/192, 49.0% male; 104/192, 54.2% Hispanic; and 73/192, 38.0% overweight or obese) wore an accelerometer and completed up to 7 EMA prompts per day for 8 days during nonschool time, reporting on past 2-h sports or exercise and TV, videos, or video games. Multilevel models were used to assess the relationship between the accelerometer-measured ST and EMA-reported TV, videos, or video games. Given the zero-inflated distribution of MVPA, 2-part models were used assess the relationship between the accelerometer-measured MVPA and EMA-reported sports or exercise.

RESULTS

EMA-reported TV, videos, or video games were associated with a greater accelerometer-measured ST (beta=7.3, 95% CI 5.5 to 9.0, P<.001). This relationship was stronger in boys (beta=9.9, 95% CI 7.2 to 12.6, P<.001) than that in girls (beta=4.9, 95% CI 2.6 to 7.2, P≤.001). EMA-reported sports or exercise was associated with a greater accelerometer-measured MVPA (zero portion P<.001; positive portion P<.001). This relationship was stronger on weekends, in older children, and in non-Hispanic children (zero portion all P values<.001; positive portion all P values<.001).

CONCLUSIONS

EMA reports highly relate to accelerometer measures. However, the differences in the strength of association depending on various demographic characteristics suggest that future research should use both EMA and accelerometers to measure activity to collect complementary activity data.
Some Peripheral Biofeedback Modules in the Treatment of Chronic Diseases in Children
Authors: Nada Pop-Jordanova , Tatjana Zorcec
Published: December 2017

Biofeedback therapy is a non-drug treatment in which patients learn to control bodily processes that are normally involuntary, such as muscle tension, blood pressure, or heart rate. In this paper we present results obtained with Electro Dermal Response (EDR) and Heart Rate Variability (HRV) applied as adjuvant therapy in chronic pediatric patients. The methodology can be used in scholar settings for stress reducing in pupils and teachers.

The evaluated group comprises children and adolescents with: a) cystic fibrosis (N = 40 mean age = 17.5 years ± 23.18 SD); b) bronchial asthma (N = 35, mean age = 11.5 years ± 18.84 SD); c) epilepsy (N = 45, mean age = 13.5 years ± 15.34 SD); and d) diabetes mellitus (N = 30, mean age = 12.5 years ± 12.3 SD).

Study showed that peripheral biofeedback is very helpful tool for chronic disorders in children. Both (EDR and HRV) methods confirmed changes on the stress level very significantly. This therapy is non-invasive, easy for application, children accept it with interest and it is cost-effective.

Research presented in this paper deals with the unknown behavior pattern of students in the blended learning environment. In order to improve prediction accuracy it was necessary to determine the methodology for students` activities assessments. The Training set was created by combining distributed sources – Moodle database and traditional learning process. The methodology emphasizes data mining preprocessing phase: transformation and features selection. Information gain, Symmetrical Uncert Feature Eval, RelieF, Correlation based Feature Selection, Wrapper Subset Evaluation, Classifier Subset Evaluator features selection methods were implemented to find the most relevant subset. Statistical dependence was determined by calculating mutual information measure. Naïve Bayes, Aggregating One-Dependence Estimators, Decision tree and Support Vector Machines classifiers have been trained for subsets with different cardinality. Models were evaluated with comparative analysis of statistical parameters and time required to build them. We have concluded that the RelieF, Wrapper Subset Evaluation and mutual information present the most convenient features selection methods for blended learning environment. The major contribution of the presented research is selecting the optimal low-cardinal subset of students’ activities and a significant prediction accuracy improvement in blended learning environment.
TRANSLATION TECHNIQUES REVISITED: THE APPLICABILITY OF EXISTING SOLUTIONS IN NON-LITERARY TRANSLATION
Authors: Đorđević Jasmina
Published: December 2017

Translation studies have evolved to the extent that phenomena, problems and aspects related to translation are analysed and defined within the discipline itself based on methods and techniques specifically developed for it. One of the many achievements is that two separate translation genres have been identified, i.e. literary and non-literary translation, followed by different approaches to both theoretical explorations of the two, as well as practical solutions in the process of translating them. The aim of this article is to contribute to the study of non-literary translation by offering an overview of translation techniques available in the literature but not yet distinctly related to non-literary translation. Since recent approaches to the study of translation imply a strong focus on the target text as a product, the techniques illustrated here are supported by examples originating from an authentic corpus of non-literary translation compiled during twenty-two years of officially recognized translation.
ECONOMIC CRIMINAL LAW - COMPARATIVE OUTLOOK
Authors: Serjević Vanja
Published: December 2017

The criminal liability of legal entities has been in the focus of the criminal law reforms over the last century, especially in the modern globalization era. The theoretical debate and the creative judicial practice in cases of serious illegal behavior of corporations have provided the necessary vehicle for change from the traditional conception that legal persons cannot be liable under criminal law (‘societas delinquere non potest’) to the newly embraced doctrine of ‘respondeat superior’ (with some modification). The article presents an overview of the major concepts and theories of the criminal liability of legal entities. After providing a comprative overview of relevant legislation in the prominent criminal law systems of the United States of America, Germany and the European Union, the author provides a general overview of the Serbian legislation on this matter.
