Published: August 2019

Resumen La presente investigación se orienta a comprender los beneficios que generan las redes según su origen en el proceso de internacionalización acelerado de los emprendimientos. Se tomó como referencia el surgimiento de Born Global, International New Venture (INV) y el enfoque de Networking. Se aplicó un método inductivo e interpretativo mediante la técnica de entrevistas en profundidad, triangulada con información pública disponible. Se seleccionó dos empresas con orientación a los mercados internacionales, desde sus primeros años de creación. Se analizaron los transcripciones mediante matrices, que se interrelacionaron con los constructos identificados en los entrevistados. El análisis permitió la elaboración de una cronología de los casos para luego identificar a las redes por origen, beneficios y estrategias que se relacionan con el modelo de internacionalización acelerado. Los resultados mostraron una tipología diversa de redes por origen: familiares, experiencia de trabajo previa, académicas (pre-grado y post-grado), eventos, institucionales (públicos y privados) y socios, que promueven el proceso de internacionalización acelerado con: contactos, soporte emocional, conocimiento (lecciones, experiencias, entre otros), recursos (monetario y no monetario), confirmación de equipos y contactos (más redes), en los factores del modelo de Born Global y International New Venture. La investigación concluye que los productos con baja demanda local y con nichos de mercado internacionales son un contexto adecuado para el surgimiento de Born Global o International New Venture, y que las redes en la etapa de pre - fundación orientan la estrategia de internacionalización, y estas a su vez guían el crecimiento y evolución de las redes en las etapas del proceso emprendedor.
The “blind spots” of organizational theories according to Guerreiro Ramos
Authors: WEBERING SUSANA IGLESIAS
Published: August 2019

Resumo Este artigo se baseia em dois livros de Alberto Guerreiro Ramos, Administração e contexto brasileiro e A nova ciência das organizações: uma reconceituação da riqueza das nações, e tem por objetivo apresentar os principais aspectos das teorias organizacionais analisados pelo autor, que os denomina “pontos cegos”. São quatro os pontos cruciais que as teorias organizacionais não suprem e, ao se desenvolverem, absorveram conceitos que foram transformados: a) a noção de racionalidade, que domina não só os Estudos Organizacionais, como também a economia, a ciência política e as ciências sociais; a b) não distinção entre significado substantivo e significado formal de organização; c) as teorias organizacionais não têm clara compreensão do papel das interações simbólicas; e, por último, d) as teorias organizacionais se apoiam somente em uma visão mecanomórfica do homem. Os pontos, que são aprofundados ao longo das duas obras, aparecem enumerados em um capítulo específico de A nova ciência das organizações. A impressão é de que o próprio Guerreiro Ramos tenha sentido essa necessidade, como uma breve recapitulação, antes de propor seu modelo multidimensional de sociedade (que não é abordado neste artigo). Isso se dá pela amplitude e profundidade da obra de Guerreiro Ramos. Exemplo disso são as possíveis agendas para seu estudo já elaboradas por diversos outros autores. Conclui-se que o pensamento de Guerreiro Ramos se mantém atual, suas críticas e preocupações são pertinentes e mostram-se fundamentais para os que pretendem desenvolver estudos críticos na área de organizações, em seu ensino e no desenvolvimento de outras possibilidades de gestão.

Abstract Competitions are considered of paramount importance for high-performancesports because they determine the entire orientation of the training process. When analyzing the calendar of the International Basketball Federation, it can be observed that international competitions occur in short periods of time. In this sense, the aim of this study was to verify the effects of the application of combined training in the short-term preparation period on the speed of athletes of the Brazilian women’s basketball team. Thirteen athletes participated in this study, who took part of the preparation for the 2015 Pan American Games. Athletes were submitted to anthropometric measures and biomotor capacity evaluation at cyclic speed -20m run, and acyclic speed - T test at the beginning (M0) and end of a 27 - day preparation period (M1). Considering the period available for training, the total duration percentage was:technical / tactical 73.7%, strength and conditioning: 5.7%, preventive: 10.5% and general and special warm up: 10.1%. After data collection, the Shapiro-Wilk test was used to verify normality and then, the Student’s T test was also applied. The main results indicate that the best time to evaluate cyclic speed (M0 and M1, respectively) was 3.34 ± 0.22s and 3.39 ± 0.21s and acyclic speed (M0 and M1, respectively), 9.30 ± 0.49s and 9.52 ± 0.57s.The results of the current study suggest that short-term intervention was not efficient to improve the cyclic and acyclic speed of female basketball athletes.

Published: August 2019

ABSTRACT Bioretention is a technique applied to treat and reduce runoff generated in urban areas. Although these facilities present complex processes, a simple model with few parameters can be useful for its project. This paper reports an application of Puls method as a bioretention simulation quantitative tool for events. A bioretention device in real scale was installed and monitored using four level sensors and a tipping-bucket rain gauge, both with data loggers. The method was applied in two ways: the facility as a single reservoir; and the facility as two serial reservoirs. Outflows depended on a single infiltration rate in the first case (K) and two infiltration rates in the second case (K1 and K2). The study used 15 events. Results showed suitable values for Nash-Sutcliffe (NS) and determination coefficients (R2) in the calibration phase, especially for bioretention simulated as a single reservoir, with NS values ranging from 0.64 to 0.95. NS ranged from 0.80 to 0.95 in the calibration phase for the device simulated as two serial reservoirs. The validation phase achieved lower NS and R2 than calibration phase. Despite this, the present study suggests the Puls model as a good option for research on bioretention devices modelling.
3D Volumetric Modeling with Introspective Neural Networks
Authors: Huang Wenlong , Lai Brian , Xu Weijian , Tu Zhuowen
Published: August 2019

In this paper, we study the 3D volumetric modeling problem by adopting the Wasserstein introspective neural networks method (WINN) that was previously applied to 2D static images. We name our algorithm 3DWINN which enjoys the same properties as WINN in the 2D case: being simultaneously generative and discriminative. Compared to the existing 3D volumetric modeling approaches, 3DWINN demonstrates competitive results on several benchmarks in both the generation and the classification tasks. In addition to the standard inception score, the Frechet Inception Distance (FID) metric is´ also adopted to measure the quality of 3D volumetric generations. In addition, we study adversarial attacks for volumetric data and demonstrate the robustness of 3DWINN against adversarial examples while achieving appealing results in both classification and generation within a single model. 3DWINN is a general framework and it can be applied to the emerging tasks for 3D object and scene modeling.1
Video Object Detection with Locally-Weighted Deformable Neighbors

Published: August 2019

Deep convolutional neural networks have achieved great success on various image recognition tasks. However, it is nontrivial to transfer the existing networks to video due to the fact that most of them are developed for static image. Frame-byframe processing is suboptimal because temporal information that is vital for video understanding is totally abandoned. Furthermore, frame-by-frame processing is slow and inefficient, which can hinder the practical usage. In this paper, we propose LWDN (Locally-Weighted Deformable Neighbors) for video object detection without utilizing time-consuming optical flow extraction networks. LWDN can latently align the high-level features between keyframes and keyframes or nonkeyframes. Inspired by (Zhu et al. 2017a) and (Hetang et al. 2017) who propose to aggregate features between keyframes and keyframes, we adopt brain-inspired memory mechanism to propagate and update the memory feature from keyframes to keyframes. We call this process Memory-Guided Propagation. With such a memory mechanism, the discriminative ability of features in keyframes and non-keyframes are both enhanced, which helps to improve the detection accuracy. Extensive experiments on VID dataset demonstrate that our method achieves superior performance in a speed and accuracy trade-off, i.e., 76.3% on the challenging VID dataset while maintaining 20fps in speed on Titan X GPU.
Skeleton-Based Gesture Recognition Using Several Fully Connected Layers with Path Signature Features and Temporal Transformer Module

Published: August 2019

The skeleton based gesture recognition is gaining more popularity due to its wide possible applications. The key issues are how to extract discriminative features and how to design the classification model. In this paper, we first leverage a robust feature descriptor, path signature (PS), and propose three PS features to explicitly represent the spatial and temporal motion characteristics, i.e., spatial PS (S PS), temporal PS (T PS) and temporal spatial PS (T S PS). Considering the significance of fine hand movements in the gesture, we propose an ”attention on hand” (AOH) principle to define joint pairs for the S PS and select single joint for the T PS. In addition, the dyadic method is employed to extract the T PS and T S PS features that encode global and local temporal dynamics in the motion. Secondly, without the recurrent strategy, the classification model still faces challenges on temporal variation among different sequences. We propose a new temporal transformer module (TTM) that can match the sequence key frames by learning the temporal shifting parameter for each input. This is a learning-based module that can be included into standard neural network architecture. Finally, we design a multi-stream fully connected layer based network to treat spatial and temporal features separately and fused them together for the final result. We have tested our method on three benchmark gesture datasets, i.e., ChaLearn 2016, ChaLearn 2013 and MSRC-12. Experimental results demonstrate that we achieve the state-of-the-art performance on skeleton-based gesture recognition with high computational efficiency.

Published: August 2019

Difficulties of primary school students in solving mathematical problems that require problem solving or reasoning abilities indicate the existence of problems in the process of learning mathematics, because one of the purposes of learning mathematics in primary school is to develop the students’ mathematical problem-solving skills. As a solution to overcome the problems, this research aims at understanding how the implementation of the guided discovery learning model influences mathematical problem-solving skills. This research employs a quasi-experimental design by involving all fifth-grade students at one of primary schools in Tebo Regency, Jambi. The simple random sample was conducted to obtain class VB as experimental class, and class VA as control class. Based on the results of the final score, experiential class obtained an average score of 86.00, and control class obtained an average score of 76.93.  The results of hypothesis test using t-test obtained tcount = 2,203 > ttable = 2,020, which indicated that H0 was rejected, and H1 was accepted. Therefore, the guided discovery learning model influenced the fifth-grade students’ mathematical problem-solving skills, thus it is recommended for teachers to be able to use the guided discovery learning model in the mathematics learning process.

Authors: Dogra Kusum , Tanwar Meenakshi
Published: August 2019

Background: Preterm birth defined as birth before 37 weeks of gestation is a significant public health issue. Identification of patients at risk of preterm labour while ruling out those who are not is a fundamental but challenging goal for clinicians. This study was done to evaluate bed side dipstick test for detecting fetal fibronectin in cervico-vaginal secretions as a predictor of preterm delivery in symptomatic and asymptomatic high risk group.Methods: This was a hospital based prospective, double blinded study. We enrolled 100 pregnant women presenting with or without symptoms of preterm delivery, between 20 and 35 weeks of gestation. A rapid bed side dipstick test was performed to detect FFN in cervico-vaginal secretions of all enrolled women (symptomatic and asymptomatic high risk women) and results were evaluated for prediction of preterm labour. Qualitative data were analyzed by using Chi-square and Fisher’s exact test and quantitative data were analyzed by using unpaired Student’s t test and Mann-Whitney test. P value < 0.05 was considered significant.Results: In symptomatic group sensitivity, specificity, PPV and NPV of FFN test in predicting delivery within 48 hours, 7days 14days and preterm delivery was 100%, 63.2%, 46.2%, 100%; 100%, 72.7%, 65.4%, 100%; 100%, 75%, 69.2%, 100%; 80%, 76%, 76.9%, 79.2% respectively. In asymptomatic high risk group, sensitivity, specificity, PPV and NPV of FFN test in predicting preterm delivery (<37weeks) was 0%, 87.5%, 0%, 77.8%.Conclusions: The high negative predictive value may be of value in avoiding unnecessary interventions with potentially hazardous medications and identifying symptomatic women who are not in true labour and also allaying anxiety of asymptomatic high risk women.

Authors: Sreedevi Rajsree , Paul Jose , Jose George , Majeed Abdul
Published: August 2019

Due to the rarity of congenital chylous ascites and the lack of standards in diagnosis and therapy, this disease constitutes a medical challenge and individual therapy seems to be extremely important. A late preterm newborn with antenatally diagnosed ascites was born and chylous ascites was diagnosed after feeds were started. The baby was managed initially with nil per oral, parenteral nutrition and octreotide, followed by adding MCT formula feeds. Considering the rarity of neonatal chylous ascites and the non-uniformity in management plans and follow up, more case reports need to be published. Also, MCT formula, the main stay of management has to be discontinued as soon as possible with gradual introduction into breast feeds or normal newborn formula milk as long chain fatty acids are essential for optimal brain growth in newborns.

Published: August 2019

Background: Self-prescription is when an individual self-recognizes his/her illness or symptoms thereby consume medications without a doctor’s supervision. Paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs) are common medications taken by young individuals. The great availability of these drugs and the individual’s education level are all important factors that contribute to the pattern of self-treatment. The aim of this study is to assess the paracetamol and NSAIDs use by self-prescription among health sector students in Imam Abdulrahman Bin Faisal University in Dammam, Saudi Arabia.Methods: 600 health sector students from IAU were involved in a cross-sectional study that was done from January 2019 to February 2019. An electronic questionnaire was used to gather information about socio-demographic data, consumption features of paracetamol and NSAIDs, and reasons for consumption without prescription. Systematic random sampling was done to select the study population.Results: 513 students out of 600 were dependent on self-prescription; therefore, the remaining 87 were excluded from the study. 85.77% of students are between 20-23 years were most of them are female medical students. Pharmacies and retails were reported by more than half (89.47%) as the main sources of obtaining paracetamol and NSAIDs. 90.25% used these medications based on their own experience as they believed they have good knowledge. Moreover, half considered prescriptions to be unnecessary and time wasting.Conclusions: The findings of the study could reflect the need for revising the medical services in the university in particular and the whole country, as the study shows that most of the youth relay on self-medication.
Evaluation of functional outcome of arthroscopic anterior cruciate ligament reconstruction by modified AMP technique
Authors: Gupta Saurabh , Garg Meenakshi , Singh Raj
Published: August 2019

Background: In anterior cruciate ligament (ACL) reconstruction, transtibial (TT) drilling of the femoral tunnel has been criticized for its vertical and less anatomical tunnel, which accompanied rotational instability of knee. Antero medial portal (AMP) drilling technique creates more oblique and anatomic femoral tunnel. However, recent researches show that oblique tunnel is related to risks of too short femoral tunnel, blowout of back wall, and posterolateral structures injury. Modified AMP technique creates vertical tunnel with anatomical FSP (femoral starting point).

Methods: In our study we have functionally evaluated 30 patients of ACL tear who underwent reconstruction by modified AMP technique. Modified AMP technique creates vertical tunnel with anatomical FSP.

Results: Mean postoperative Lysholm score is 94.4±1.22 and mean postoperative subjective IKDC score is 93.308. All the cases of ACL tear reported their knees as normal or near normal according to objective IKDC score after reconstruction. Mean coronal angle is 51.112±6.3 and mean femoral tunnel length is 41.8±3.55 mm while posterior wall blowout of lateral femoral condyle and postero lateral structure injury has not been observed.

Conclusions: The modified AMP technique provides an anatomic and safe mode with vertical tunnel and oblique graft, by reduces the risks involved in the AMP technique.

Published: August 2019

Neste trabalho, avaliou-se o efeito da concentração de glicerol nas propriedades de filmes de proteína de soja (IPS) incorporados de óleo essencial de orégano (OEO). As concentrações de glicerol testadas foram de 20, 25 e 30 g de glicerol/100 g de IPS, e a concentração de OEO utilizada foi de 3% (m/m) em relação à solução filmogênica. O aumento na concentração de glicerol com a presença de OEO promoveu diminuição no módulo de Young, resistência à tração e aumento no alongamento à ruptura e permeabilidade ao vapor de água. Entretanto, em alta concentração de glicerol e OEO o filme mostrou migração aparente desses compostos.  Filmes de IPS com OEO apresentaram atividade antimicrobiana frente a E. coli e S. aureus, e significativa atividade antioxidante (medida pelos métodos DPPH e ABTS), independentemente da concentração de glicerol. Os filmes apresentados são uma opção promissora de embalagens ativas ambientalmente corretas para serem utilizadas na conservação de alimentos.

Concentrations of PCDD/Fs in Human Blood: A Review of Data from the Current Decade
Authors: Marquès Montse , Domingo Jose L
Published: August 2019

Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-p-furans (PCDD/Fs) are environmental pollutants with a great persistence, capacity of bioaccumulation, and well known important toxic effects in humans and animals. Incinerators of hazardous, municipal and medical waste, chlorine bleaching of paper pulp, cement plants, and the traffic of motor vehicles are the most frequent emission sources of these compounds. The diet, followed at a great distance by inhalation, is generally the main way of human exposure to PCDD/Fs. Human biomonitoring is of a great importance to prevent potential adverse effects derived from exposure to chemicals such as PCDD/Fs. In relation to this, blood is among the most used biological monitors. In the current review, we have summarized the recent information (2000-2009) published in the scientific literature (databases: Scopus and PubMed) on the concentrations of PCDD/Fs in blood samples of non-occupationally exposed populations, as well as in some groups of occupationally exposed individuals. We have revised a number of studies conducted in various African American, Asian and European countries, and Australia. Unfortunately, the information is quite limited. No data are available for most countries over the world. Based on the results here reviewed –where available- the current health risks for the general populations do not seem to be of concern. Moreover, taking into account the important reductions observed in the levels of PCDD/Fs in foodstuffs, new decreases in the concentrations of PCDD/Fs in blood -and other biological tissues- are very probable in the immediate years.
Coordinated Development of Agricultural Water Resources and Socio-Economy in Shanxi Province Considering Uncertainty

Conflict between agricultural water resources and socio-economy development is a global problem. Accurate evaluation of coordinated development of agricultural water resources and socio-economy and risk mitigation is necessary for sustainable development. An evaluation method, including selection of criteria, data collection, determination of weight, evaluation of coordinated development, prediction of parameters, and judgment of coordinated development state, has been proposed to study coordinated development degree. To deal with uncertainties, Monte Carlo method and fuzzy set method were used. The method is demonstrated to solve a real-world evaluation problem in Shanxi Province in the middle of China. Results show that coordinated development degrees were (0.7, 0.8) for most of the cities of Shanxi in 2015, indicating that coordinate development state was intermediate coordinate. To achieve balanced development, more attention should be put on socio-economic development in Taiyuan and Yanquan, and agricultural water resources utilization in Jinzhong, Yuncheng and Xinzhou. The average coordinated development degree is 0.758, and coordinate development state was intermediate coordinate from 2006 to 2015. Coordinated development degree has a trend of decreasing markedly, coordinate development state will be barely coordinated, and agricultural water resources utilization lags behind socio-economic development in 2020. The study demonstrates the practicability of the improved method, by evaluating coordinated development degree under uncertainty and forecasting future risks, which will conduce to promote sustainable development of agricultural water resources and socio-economy.

The term hoodlum is associated with vicious activities while ikhwan is associated with religious activities. Phenomenon appeared when religious activities conducted by ikhwan eks hoodlum. This phenomenon appeared in Mojo village, Semanggi, Pasar Kliwon, Surakarta. This village had bad history. Any kind of bad activities were found in this village but the social life changed since 1999. The villagers agreed to close three prostitution locations in this village. Then, Islamic invitation came to hoodlums, step by step, their lives changed to be better. Researcher divides their lives into three periods. First, they were being good Muslims; second, they joined to lascar activities, third, the period after the general leader of lascars died. Based on this reality, researcher focused this study on the Islamic understanding of ikhwan eks hoodlum, some factors that shaped their understandings, and the impacts of their Islamic understandings. This study used qualitative method with interactiosme symbolic approach. This theory said that human being activities based on their symbol understanding. This understanding was formed by social interacts. To support this method, the writer used social learned and Islamic invitation (dakwah) that shaped their Muslim personalities. Among three periods, lascar period took more proportions. They joined sweeping violent activities and they against many hoodlums physically. These activities made many hoodlums areas be Islamic village. Apart from that, second period have produced extreme thought of some ikhwan.

Transportation, handling, and corrosion damage to the threads of oilfield tubulars cost the industry millions of dollars each year. This problem has intensified with the increased use of proprietary connections which represent a significant percentage of the total tubular cost. The thread protector is the primary means of protecting the threads from impact and corrosion damage. Exxon Production Research Company has designed a test program and built a test facility to evaluate the performance of oilfield thread protectors. A wide variety of thread protectors were evaluated which included metal, plastic, and composite (metal-elastomer) designs. This paper discusses this testing and outlines a guide for the selection of oilfield thread protectors for various service conditions.

Carboxymethyl sago starch (CMSS) hydrogel was prepared by dissolving CMSS in HCl solution under vigorous stirring to form gel. The parameter studied were the effect of the percentage of CMSS, concentration of the acid solution, reaction time and reaction temperature to identify the optimum condition of preparation of CMSS hydrogel. 60% of CMSS in 2.0M acid solution for 12 hours reaction time at room temperature were the optimum conditions for CMSS hydrogel. The hydrogel was characterized by using Fourier Transform Infrared (FT-IR), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). FTIR spectrum of CMSS shows an additional absorption band at 1597 cm-1 indicating the substitution of CH2COO-Na+ group on the starch molecular chain during carboxymethylation, while the spectrum of CMSS hydrogel shows an additional sharp absorption band at 1723 cm-1 indicating that the Na in CMSS being exchanged to H from hydrochloric acid solution. SEM image of CMSS hydrogel shows pores in structure and connected to each other to form networks. TGA curve shows that the maximum rate of thermal decomposition of CMSS hydrogel is higher than CMSS at 330.22 ºC with 60.22% major weight loss. This could be due to the presence of the cross-linkages in the CMSS hydrogel. CMSS hydrogel gives high swelling degree in PBS solution at pH 7 and low swelling degree in acidic medium.
