Authors: Maulana Hutomo Atman
Published: December 2018

Curah hujan merupakan salah satu faktor iklim yang berpengaruh di berbagai bidang sehingga pemerintah membangun stasiun hujan untuk mengukur curah hujan di lokasi tertentu di Indonesia yang dianggap memiliki potensi. Akan tetapi curah hujan di luar daerah stasiun hujan tidak diketahui secara pasti, sehingga perlu dilakukan prediksi curah hujan dengan menggunakan analisis deret waktu dengan metode Box-Jenkins yang dikenal dengan Autoregressive Integrated Moving Average (ARIMA), maupun analisis krigging untuk melihat kebergantungan spasial lokasi. Identifikasi model dilakukan dengan meihat plot ACF dan PACF data. Data yang digunakan adalah data curah hujan di Bogor periode 10 harian dari bulan Januari 2013 - Desember 2014 sehingga diperoleh model deret waktu terbaik untuk 12 stasiun yang terdiri dari ARIMA(1,1,1), ARIMA(1,1,0), dan ARIMA(3,1,0).

Objectives. To examine the effect of patient navigation models on changes in housing status and its subsequent effects on HIV outcomes for 700 people living with HIV (PLWH) who were unstably housed with co-occurring substance use and psychiatric disorders across 9 demonstration sites in the United States between the years of 2013 and 2017.

Methods. Self-reported housing status was collected at baseline, and at 6 and 12 months during the intervention. HIV outcomes included linkage and retention in care, antiretroviral therapy prescription, and viral suppression collected via chart review.

Results. In the 12 months after the intervention, 59.6% transitioned to more stable housing. Compared with those who became or remained unstably housed, participants with greater stability achieved significantly higher rates of retention (adjusted odds ratio [AOR] = 2.12; 95% confidence interval [CI] = 1.11, 4.05), were more likely to be prescribed antiretroviral therapy (AOR = 2.06; 95% CI = 1.62, 2.63), and had higher rates of viral suppression (AOR = 1.62; 95% CI = 1.03, 2.55).

Conclusions. The use of patient navigators to create a network of services for PLWH who are unstably housed can improve housing stability and lead to improvements in HIV-related outcomes.
Digital Current Measurement Element for Operation During Current Transformer Severe Saturation

Published: December 2018

The development and implementation of a digital current measurement element for proper operation during current transformer (CT) magnetic core severe saturation are considered. CT transient performance is often accompanied by primary current transformation to secondary one with great errors. In this case the secondary CT current which is an input signal of the digital measurement element differs from the ideally transformed CT current both in shape and magnitude. This causes impermissible signal settling time at the standard digital measurement element output. As a result, main requirements to the protection devices such as reliability and fast operation are violated, that in some cases makes the high-speed protection device ineffective. To solve this problem, it is proposed to form the output signal of the digital current measurement element in depending on the input signal total harmonic distortion (THD) coefficient value. Moreover, it is worthwhile to form the output signal so that for a low CT saturation conditions this output signal slightly differs from the secondary current RMS value, and for a severe CT saturation conditions it exceeds this value. Digital current measurement element model has been developed and implemented in the MatLab-Simulink environment using the following blocks: a digital filter block responsible for the input signal fundamental frequency component magnitude calculation; a digital filter block responsible for the input signal RMS value calculation; and, also, a standard blocks for basic mathematical calculations needed for proper functioning of the proposed measurement element. The functional testing of the proposed digital current measurement element model was carried out using the signal, that was similar in form to the waveform of the secondary current of the severe saturated CT. The tests that had been performed confirmed that the proposed digital current measurement element in comparison with the standard current measurement element ensures stable functioning and enhanced operation time during transients.
The Permissible under Heating Conditions Torque of a Frequency-Controlled Synchronous Motor of Permanent Magnets
Authors: Firago B. I. , Aleksandrovsky S. V.
Published: December 2018

The variable speed electrical drives for industrial mechanisms with a constant static torque usually operate in a large range of speeds and loads. Along with this, for any speed of a given range the electrical drive motor is to provide a continuous permissible torque without overheating. Mostly the electrical motors have self-ventilation; the ventilator being located on the motor shaft. In such motors heat dissipation depends on a motor speed. The permissible continuous motor torque is determined out of a heat balance equation where power losses being converted into heat must be transferred in the ambient space and the motor temperature must not be over a permitted level for a given class of winding insulation under the certain ambient temperature. A heat balance equation is usually obtained on a basis of a one-mass motor heat model, i. e. the model that was used in this research. But even the one-mass heat model gives a non-linear heat balance equation. In order to get convenient analytical expressions out of the motor heat balance equation, it is necessary to take some justified assumptions; the latter was also implemented in this research. As a result, formulas have been obtained by which the long-term permissible motor torque can be calculated as a function of the relative speed of the rotor at a given ambient temperature. For the examples presented in the articles we chose (20 and 40 °С as a standard temperature for the thermal calculation of electrical machines). Dependences of a relative permissible continuous motor torque m on a relative frequency value (or relative rotor speed) are presented for three synchronous motors with permanent magnets and rated power of 3; 25 and 250 kW.

Authors: Zhu Mijia , Yin Xianqing , Chen Wu , Yi Zhengji , Tian Heyong
Published: December 2018

The removal of sulphate ions constitutes one of the main challenges in mining, metallurgical and other industries. This work evaluated sulphate removal from aqueous solutions by an electrocoagulation (EC)/raw straw activated carbon (RSAC) adsorption coupled process. The process parameters affecting sulphate removal efficiency were investigated: current density (0–100 mA/cm2), RSAC dosage (0–0.8 g/L), initial pH (4–9) and reaction time (0–40 min). A central composite design coupled with response surface methodology (RSM) was used to construct a mathematic model of EC/RSAC process that considers three key variables, namely current density, RSAC dosage and reaction time. Under optimum conditions (current density of 75 mA/cm2, dosage of 0.46 g/L and reaction time of 19.2 min), the removal efficiency of sulphate reached 95.2%. The RSM predictive value was 94.08% with a small deviation (1.12%). Thus, the fundamental data and results can provide some useful information for further studies and applications of the EC/RSAC coupled system in sulphate-containing wastewater treatment.

Published: December 2018

The wastewater from food-processing industries is generally heavily charged with lipids and proteins. Flotation process is commonly applied to separate the hydrophobic material phase, producing flotation froth, a waste that has high levels of fats and proteins. Enzymatic hydrolysis may be used to overcome the difficulty of fat biotransformation in a subsequent anaerobic digestion. In the present work, wastes from the flotation process of two industries (dairy and poultry slaughterhouse) were hydrolyzed with a commercial lipase and without enzyme addition (control). The effect of adjusting the pH at the beginning of the hydrolytic assays was also investigated. The long chain free fatty acids (LCFAs) released were identified and quantified and 5-d digestion assays were conducted with the hydrolyzed material. The results indicated that the hydrolysis assays conducted with initial pH adjusted to 7.0 and the utilization of a commercial enzyme promoted a higher increase in amounts of LCFAs, particularly of unsaturated acids. In most anaerobic digestion assays, the specific methane production showed a decreasing trend with the increase of unsaturated fatty acids in the medium. In general, the utilization of a commercial enzyme (lipase) in the hydrolysis process did not contribute to enhancing methane production in 5-d anaerobic digestion assays.

Authors: Lian Yu , Mai Lei , Cromar Nancy , Buchanan Neil , Fallowfield Howard , Li Xiaoming
Published: December 2018

Natural ultraviolet irradiance disinfection is known to play a significant role in both natural wastewater treatment systems and drinking water disinfection processes, while the influence of ultraviolet B (UVB) delivering method on sunlight disinfection outcome is still unclear. This study aims to determine the effects of environmentally relevant temperatures, UVB doses (J m−2) and dose rates (W m−2) on the inactivation and log reduction values (LRVs) of the F-RNA coliphage MS2 and Escherichia coli in optically clear water. E. coli and MS2 were separately incubated and irradiated at five different doses of UVB light that delivered using six UVB dose rates. The results of the study demonstrate that the UVB dose delivering method (combination of dose rate and exposure time) influences inactivation and LRVs of E. coli and MS2 at all UVB doses investigated (up to seven-fold difference). Two phases were identified within the UVB dose rate, UVB inactivation or LRV curves for both organisms; a UVB dose rate limited inactivation phase and a dose rate saturation inactivation phase. The results contribute to a better understanding of UVB disinfection in the environment and natural wastewater treatment systems, potentially improving the design and operation of high rate algal ponds.
¿Ciudades gemelas? Posadas, Argentina y Encarnación, Paraguay en perspectiva sociourbana
Authors: Brites Walter Fernando
Published: December 2018

El objetivo de este artículo es evidenciar los procesos de relacionamientos complementarios que mantienen las ciudades fronterizas de Posadas, Argentina y Encarnación, Paraguay. Desde un abordaje descriptivo y diacrónico el estudio sostiene que estás ciudades pueden ser interpretadas como ciudades gemelas que comparten una historia de relaciones en el contexto regional. Al margen de sus especificidades, ambas ciudades presentan aspectos sociourbanos similares, y en su devenir estuvieron implicadas en los mismos procesos y problemas: flujos fronterizos, políticas del Mercosur, construcción del puente internacional, acuerdos de Tránsito Vecinal Fronterizo, y hasta un fenómeno más inusual, como la impronta que grandes obras de infraestructuras han dejado en sus territorios. Se concluye que estas ciudades, a pesar de no contar con un gobierno común, sostienen relaciones económicas, culturales, de vecindad y complementariedad que producen impactos en una ciudad y viceversa, generando interdependencias, mutuos condicionamientos y una forma específica de articulación interurbana.

Authors: Jing Pan , Shi Min , Ma Liang , Fu Ping
Published: December 2018

Hyperuricemia, defined as the presence of elevated serum uric acid (sUA), could lead to urate deposit in joints, tendons, kidney and other tissues. Hyperuricemia as an independent risk factor was common in patients during the causation and progression of kidney disease. Uric acid is a soluble final product of endogenous and dietary purine metabolism, which is freely filtered in kidney glomeruli where approximately 90% of filtered uric acid is reabsorbed. Considerable studies have demonstrated that soluble uric acid was involved in the pathophysiology of renal arteriolopathy, tubule injury, tubulointerstitial fibrosis, as well as glomerular hypertrophy and glomerulosclerosis. In the review, we summarized the mechanistic insights of soluble uric acid related renal diseases.
Heat Shock Proteins (HSPs): A Novel Target for Cancer Metastasis Prevention
Authors: Narayanankutty Vinayak , Narayanankutty Arunaksharan , Nair Anusree
Published: December 2018

Background:

Heat shock proteins (HSPs) are predominant molecular chaperones which are
actively involved in the protein folding; which is essential in protecting the structure and functioning
of proteins during various stress conditions. Though HSPs have important physiological roles, they
have been well known for their roles in various pathogenic conditions such as carcinogenesis; however,
limited literature has consolidated its potential as an anti-metastatic drug target.

Objectives:

The present review outlines the role of different HSPs on cancer progression and metastasis;
possible role of HSP inhibitors as anti-neoplastic agents is also discussed.

Methods:

The data were collected from PubMed/Medline and other reputed journal databases. The literature
that was too old and had no significant role to the review was then omitted.

Results:

Despite their strong physiological functions, HSPs are considered as good markers for cancer
prognosis and diagnosis. They have control over survival, proliferation and progression events of cancer
including drug resistance, metastasis, and angiogenesis. Since, neoplastic cells are more dependent
on HSPs for survival and proliferation, the selectivity and specificity of HSP-targeted cancer drugs
remain high. This has made various HSPs potential clinical and experimental targets for cancer prevention.
An array of HSP inhibitors has been in trials and many others are in experimental conditions
as anticancer and anti-metastatic agents. Several natural products are also being investigated for their
efficacy for anticancer and anti-metastatic agents by modulating HSPs.

Conclusion:

Apart from their role as an anticancer drug target, HSPs have shown to be promising targets
for the prevention of cancer progression. Extensive studies are required for the use of these molecules
as anti-metastatic agents. Further studies in this line may yield specific and effective antimetastatic
agents.

Authors: Anusionwu Chioma G. , Aderibigbe Blessing A. , Mbianda Xavier Y.
Published: December 2018

Hybrid molecule approach of drug design has become popular due to advantages such as delayed resistance, reduced toxicity, ease of treatment of co-infection and lower cost of preclinical evaluation. Antifungal drugs currently available for the treatment of fungal diseases suffer a major side effect of drug resistance. Hybrid drugs development is one of the approaches that has been employed to control microbial resistance. Their antifungal activity is influenced by their design. This review is focused on hybrid molecules exhibiting antifungal properties to guide scientists in search of more efficient drugs for the treatment of fungal diseases.
Molecular Mechanisms and Targeted Therapies Including Immunotherapy for Non-Small Cell Lung Cancer
Authors: Nagano Tatsuya , Tachihara Motoko , Nishimura Yoshihiro
Published: December 2018

Lung cancer is the leading cause of cancer death worldwide. Molecular targeted therapy has greatly advanced the field of treatment for non-small cell lung cancer (NSCLC), which accounts for the majority of lung cancers. Indeed, gefitinib, which was the first molecular targeted therapeutic agent, has actually doubled the survival time of NSCLC patients. Vigorous efforts of clinicians and researchers have revealed that lung cancer develops through the activating mutations of many driver genes including the epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), c-ros oncogene 1 (ROS1), v-Raf murine sarcoma viral oncogene homolog B (BRAF), and rearranged during transfection (RET) genes. Although ALK, ROS1, and RET are rare genetic abnormalities, corresponding tyrosine kinase inhibitors (TKIs) can exert dramatic therapeutic effects. In addition to anticancer drugs targeting driver genes, bevacizumab specifically binds to human vascular endothelial growth factor (VEGF) and blocks the VEGF signaling pathway. The VEGF signal blockade suppresses angiogenesis in tumor tissues and inhibits tumor growth. In this review, we also explore immunotherapy, which is a promising new NSCLC treatment approach. In general, antitumor immune responses are suppressed in cancer patients, and cancer cells escape from the immune surveillance mechanism. Immune checkpoint inhibitors (ICIs) are antibodies that target the primary escape mechanisms, immune checkpoints. Patients who respond to ICIs are reported to experience longlasting therapeutic effects. A wide range of clinical approaches, including combination therapy involving chemotherapy or radiation plus adjuvant therapy, are being developed.

Published: December 2018

Background:

New drugs and strategies to treat tuberculosis (TB) are urgently needed.
In this context, thiourea derivatives have a wide range of biological activities, including anti-TB.
This fact can be illustrated with the structure of isoxyl, an old anti-TB drug, which has a thiourea
as a pharmacophore group.

Objective:

The aim of this study is to describe the synthesis and the antimycobacterial activity of
fifty-nine benzoylthioureas derivatives.

Methods:

Benzoylthiourea derivatives have been synthesized and evaluated for their activity
against Mycobacterium tuberculosis using the MABA assay. After that, a structure-activity relationship
study of this series of compounds has been performed.

Results and Discussion:

Nineteen compounds exhibited antimycobacterial activity between 423.1
and 9.6 μM. In general, we observed that the presence of bromine, chlorine and t-Bu group at the
para-position in benzene ring plays an important role in the antitubercular activity of Series A.
These substituents were fixed at this position in benzene ring and other groups such as Cl, Br, NO2
and OMe were introduced in the benzoyl ring, leading to the derivatives of Series B. In general,
Series B was less cytotoxic than Series A, which indicates that the presence of a substituent at
benzoyl ring contributes to an improvement in both antimycobacterial activity and toxicity profiles.

Conclusion:

Compound 4c could be considered a good prototype to be submitted to further structural
modifications in the search for new anti-TB drugs, since it is 1.8 times more active than the
first line anti-TB drug ethambutol and 0.65 times less active than isoxyl.

The aim of this research was to study the in vitro ruminal fermentability of supplementation of Gliricidia sepium, Moringa oleifera, Lamk (MOL), Ceiba pentandra and Paraserianthes falcataria leaf meal in concentrate feed to be tested on sheep. This research with the experimental methods was arranged in Randomized Block Design (RBD) with 6 treatments and 3 groups. The treatment feed tested consisted of concentrate without leaves and concentrate with leaf meal supplementation. Crude protein content (CP) concentrates were prepared 16%, 18% and 20%. Supplementation uses a mixture of Gliricidia sepium, MOL, Ceiba pentandra and Paraserianthes falcataria leaf meal in concentrate feed (1: 1: 1: 1) as much as 10%, 20% and 30%. The measured variables were  degradation of dry matter (DDM) and degradation of organic matter (DOM), gas production rate, microbial biomass and NH3 concentration. The use of mixed leaf meal in concentrate feed resulted in in vitro DDM as well as concentrate feed without leaf meal supplementation. Supplementation of leaf meal in concentrate feed as much as 30% with CP 20% resulted in a decrease in the value of fermentability. The supplementation of leaf meal in concentrate feed as much as 20% in concentrate feed with CP 18% produced the best fermentability value. Suggested for in-vivo trials on sheep using 18% protein concentrate feed by utilizing Gliricidia sepium, MOL, Ceiba pentandra and Paraserianthes falcataria leaf meal in concentrate feed as cheap protein sources.

Measuring Regional Quality of Health Care Using Unsolicited Online Data: Text Analysis Study (Preprint)
Authors: Hendrikx Roy Johannus Petrus , Drewes Hanneke Wil-Trees , Spreeuwenberg Marieke , Ruwaard Dirk , Baan Caroline
Published: December 2018

BACKGROUND

Regional population management (PM) health initiatives require insight into experienced quality of care at the regional level. Unsolicited online provider ratings have shown potential for this use. This study explored the addition of comments accompanying unsolicited online ratings to regional analyses.

OBJECTIVE

The goal was to create additional insight for each PM initiative as well as overall comparisons between these initiatives by attempting to determine the reasoning and rationale behind a rating.

METHODS

The Dutch Zorgkaart database provided the unsolicited ratings from 2008 to 2017 for the analyses. All ratings included both quantitative ratings as well as qualitative text comments. Nine PM regions were used to aggregate ratings geographically. Sentiment analyses were performed by categorizing ratings into negative, neutral, and positive ratings. Per category, as well as per PM initiative, word frequencies (ie, unigrams and bigrams) were explored. Machine learning—naïve Bayes and random forest models—was applied to identify the most important predictors for rating overall sentiment and for identifying PM initiatives.

RESULTS

A total of 449,263 unsolicited ratings were available in the Zorgkaart database: 303,930 positive ratings, 97,739 neutral ratings, and 47,592 negative ratings. Bigrams illustrated that feeling like not being “taken seriously” was the dominant bigram in negative ratings, while bigrams in positive ratings were mostly related to listening, explaining, and perceived knowledge. Comparing bigrams between PM initiatives showed a lot of overlap but several differences were identified. Machine learning was able to predict sentiments of comments but was unable to distinguish between specific PM initiatives.

CONCLUSIONS

Adding information from text comments that accompany online ratings to regional evaluations provides insight for PM initiatives into the underlying reasons for ratings. Text comments provide useful overarching information for health care policy makers but due to a lot of overlap, they add little region-specific information. Specific outliers for some PM initiatives are insightful.
Evaluation of Self-Management Support Functions in Apps for People With Persistent Pain: Systematic Review (Preprint)
Authors: Devan Hemakumar , Farmery Devin , Peebles Lucy , Grainger Rebecca
Published: December 2018

BACKGROUND

Smartphone apps are a potential mechanism for development of self-management skills in people with persistent pain. However, the inclusion of best-practice content items in available pain management apps fostering core self-management skills for self-management support is not known.

OBJECTIVE

The aim of the study was to evaluate the contents of smartphone apps providing information on pain management strategies for people with persistent pain facilitating self-management support and to appraise the app quality.

METHODS

A systematic search was performed in the New Zealand App Store and Google Play Store. Apps were included if they were designed for people with persistent pain, provided information on pain self-management strategies, and were available in English. App contents were evaluated using an a priori 14-item self-management support (SMS-14) checklist. App quality was assessed using the 23-item Mobile Apps Rating Scale.

RESULTS

Of the 939 apps screened, 19 apps met the inclusion criteria. Meditation and guided relaxation were the most frequently included self-management strategies. Overall, the included apps met a median of 4 (range 1-8) of the SMS-14 checklist. A total of 3 apps (Curable, PainScale-Pain Diary and Coach, and SuperBetter) met the largest number of items (8 out of 14) to foster self-management of pain. Self-monitoring of symptoms (n=11) and self-tailoring of strategies (n=9) were frequently featured functions, whereas a few apps had features facilitating social support and enabling communicating with clinicians. No apps provided information tailored to the cultural needs of the user. The app quality mean scores using Mobile Apps Rating Scale ranged from 2.7 to 4.5 (out of 5.0). Although use of 2 apps (Headspace and SuperBetter) has been shown to improve health outcomes, none of the included apps have been evaluated in people with persistent pain.

CONCLUSIONS

Of the 3 apps (Curable, PainScale-Pain Diary and Coach, and SuperBetter) that met the largest number of items to support skills in self-management of pain, 2 apps (PainScale-Pain Diary and Coach and SuperBetter) were free, suggesting the potential for using apps as a scalable, wide-reaching intervention to complement face-to-face care. However, none provided culturally tailored information. Although 2 apps (Headspace and SuperBetter) were validated to show improved health outcomes, none were tested in people with persistent pain. Both users and clinicians should be aware of such limitations and make informed choices in using or recommending apps as a self-management tool. For better integration of apps in clinical practice, concerted efforts are required among app developers, clinicians, and people with persistent pain in developing apps and evaluating for clinical efficacy.

The performance evaluation of R744 transcritical ejector and R290/R744 cascade refrigeration systems for Turkey
Authors: Yilmaz Deniz , Yilmaz Baris , Mancuhan Ebru
Published: December 2018

In this study, performance of two different environmentally friendly systems with natural refrigerant solutions, R744 transcritical booster system with ejector and a R290/R744 cascade system are examined theoretically by using engineering equation solver software. Operating conditions are determined to represent different climatic regions in Turkey using summer dry bulb temperatures of various cities. The transcritical and the cascade system are assumed to operate at two different evaporation temperatures of ?10?C and ?32?C. The overall energy efficiency ratio values for each system with respect to the same ambient and evaporation conditions are compared and evaluated. Finally, performance of both systems has been compared and the appropriate solution for each city has been suggested. For cold and mild climate regions of Turkey, the performance of transcritical alternative is found better than the proposed cascade system. Moreover, the performance of transcritical system is observed slightly lower than those of the cascade system in hot climate regions of Turkey such as Aegean, Mediterranean, and South-East Anatolian regions. It is also found that the performance of the transcritical system is better in regions having lower ambient conditions such as near the Black Sea and eastern regions of Turkey. Therefore, for the mild and cold regions of Turkey, the transcritical ejector option is the better alternative due to having higher performance compared to the cascade system.

We develop Milstein-type versions of semi-implicit split-step methods for numerical solutions of non-linear stochastic differential equations with locally Lipschitz coefficients. Under a one-sided linear growth condition on the drift term, we obtain some moment estimates and discuss convergence properties of these numerical methods. We compare the performance of multiple methods, including the backward Milstein, tamed Milstein, and truncated Milstein procedures on non-linear stochastic differential equations including generalized stochastic Ginzburg-Landau equations. In particular, we discuss their empirical rates of convergence.
Bearing fault detection by four-band wavelet packet decomposition
Authors: Cekic Yalcin
Published: December 2018

Bearing problems are by far the biggest cause of induction motor failures in the industry. Since induction machines are used heavily by the industry, their unexpected failure may disturb the production process. Motor condition monitoring is employed widely to avoid such unexpected failures. The data that can be obtained from induction machines are non-stationary by nature since the loading may vary during their operation. Wavelet packet decomposition seems to better handle non-stationary nature of induction machines, the use of this method in monitoring applications is limited, since the computational complexity is higher than other methods. In this work four-band wavelet packet decomposition of motor vibration data is proposed to reduce the computational complexity without compromising accuracy. The proposed method is very suitable for parallel computational processing by its nature, and as a result it is predicted that the calculation time will be shortened further if field-progammable gate array is used in design.

Published: December 2018

El presente artículo propone una metodología para la gestión de inventario en bodegas de materia prima para industrias del sector de alimentos concentrados, de tal modo que definan políticas de control de inventario y almacenamiento. En la primera fase se realizó una clasificación ABC de los ítems. La segunda fase determinó el patrón y variabilidad de la demanda de cada ítem. De esta forma, se realizaron los pronósticos y cálculo de los inventarios de seguridad con base en la variabilidad de la demanda y el nivel de servicio deseado. Una vez definido el método de pronóstico de demanda de cada ítem, los errores del pronóstico y la estimación del último dato; en la tercera fase se definió la política de control de inventarios. Finalmente, se realizó un modelo de optimización que permitió apoyar la implementación del proceso de almacenamiento de los inventarios de materias primas. Esta metodología integra la política de control de inventario con la ubicación de este en el almacén, porque una correcta disposición de productos influye de forma directa en el control de existencias. Generando como resultado que las políticas de control de inventario impactan de forma directa en la disposición de materiales dentro del almacén.
Usos (sem abuso) do texto etnográfico em sala de aula

Published: December 2018

Qual é o lugar das narrativas etnográficas nas salas de aula da educação básica? Em que medida a forma especializada dessa escrita pode se converter em uma ferramenta pedagógica para subsidiar o trabalho docente? Em diálogo com tais indagações, o artigo propõe três maneiras de se compreender o texto etnográfico como prática escolar direcionada a não antropólogos: a exemplar, a conceitual e a etnográfica. Trata-se, portanto, de uma proposição teórico-metodológica que objetiva ampliar os espaços de circulação das perspectivas antropológicas e das maneiras de se produzir o conhecimento com a antropologia.
An empirical analysis of factors affecting sharing economy growth

Published: December 2018

Research background: There are widely recognized benefits of sharing economy for entrepreneurs and consumers. The European Commission emphasizes the importance of European countries being open to new opportunities that sharing economy brings. In order to promote the development of sharing economy, it is important to understand what factors contribute to its development.

Purpose of the article: The presented paper aims to identify the main factors relevant for the growth of sharing economy and to determine whether there are factors which are more significant for the development of the sharing economy than others. Based on reviewed literature, the Authors compiled a set of indicators and employed them for research purposes. The selected indicators were assigned into four main groups: technological, political and regulatory environment, economic and social-cultural environment.

Methods: The authors used two multicriteria methods (SAW and APH), which were applied to the set of indicators and modeled five different situations by attributing significance to the indicators. The Authors have applied this set of indicators for assessing the following selected countries:  Lithuania, Latvia, Estonia and the United Kingdom. The data covers the years 2011?2015.

Findings & Value added: The results of the research show that technological readiness and social-cultural environment are significant for the development of sharing economy. For further research the Authors recommend the creation of a composite Sharing Economy Index (SHEI).
