Authors: Jie Li , Ying Lu , Junyong Tang 
Published: June 2018

Abstract
The conventional network traffic flow models are mostly based on Poisson model. With the continuous development of network services, studies found that the actual network traffic has a long-range dependence (LRD) now and in a very long time, which is a kind of self-similarity. In this paper, RMD and Fourier algorithm were adopted to simulate and analyze a self-similar model of FGN. They generated the necessary sequence of self-similar traffic. Then the article uses R/S method to verify H value of the generated sequence of self-similar traffic in order to verify the self-similarity of the self-similar traffic sequence. The existence of self-similarity is verified by experiments, and the advantage and disadvantage of RMD and Fourier algorithm are analyzed.

Published: June 2018

Abstract
With the advent of the era of network, information technology has penetrated into many fields such as politics, economy, culture and so on. Human’s production mode, life style and learning way have changed greatly. The traditional educational mode has been unable to meet the diverse needs of students. Our educational reform and development are facing unprecedented challenges. The driving point of educational reform is to drive educational modernization with educational information. In this context, the ideological and political theory needs a new teaching model to make up for the shortcomings of the traditional teaching model. After a series of explorations, it is found that the teaching mode, which is based on classroom teaching and the network teaching is supplemented, is a new model in line with the requirements of the times. The network teaching platform of the ideological and political course has emerged as a new part of the network teaching.

Research on Robust Model for Web Service Selection
Authors: Yanxi Wei , Fan Yu , Xing Ma , Haige Yu , Wenhui Yang 
Published: June 2018

Abstract
Most existing service quality models use defined Quality of Service parameters for service selection.Since a large number of uncertainties exist, the QoS performance indicators in the runtime of the composite services obtained through the model and method based on the determined QoS will be worse even beyond the range acceptable to the users. Web services can solve this problem and become the most reasonable solution in the current application environment. Web services can solve this problem and become the most reasonable solution in the current application environment. In the process of actual service delivery, the key to the failure of the service composition to meet the requirements is caused by uncertain factors. In order to solve the above problems, this paper first proposes a local optimal selection model based on uncertain QoS. The Web service selection method based on uncertain QoS has been progressing in recent years. Second, in order to reduce the time spent on selection, a redundant service selection result is given. The experimental results on the data set show that the proposed model and method can effectively select more robust services for users.

Published: June 2018

Abstract
With the development of computer technology, especially the emergence of high resolution image sensor, aerial photogrammetry has played an important role in geological survey. Traditional aerial measurements are carried out by manned large aircraft, with a large volume of measured information and a wide range of shots. This method is suitable for large area operation, which is high and expensive for hardware site. UAV air measurement systems are usually used for small area measurements. The UAV is small and fluctuates greatly during flight, the collection of the data and images are not accurate enough. This paper has obtained the accurate measurement of image by studying the image fast matching theory, which has practical significance in the actual mapping and has higher research value.
Non-antibiotics, Efflux Pumps and Drug Resistance of Gram-negative Rods
Authors: LAUDY AGNIESZKA EWA 
Published: June 2018

Abstract
Non-antibiotic medicinal products consist of drugs with diverse activity against bacteria. Many non-antibiotics demonstrate direct anti-bacterial activity against Gram-positive cocci. The activity observed against Gram-negative rods is much lower and non-antibiotics primarily from the following groups: non-steroidal anti-inflammatory drugs, cardiovascular and antidepressant medicinal products demonstrate this activity. It has been shown that the low activity of some non-antibiotics or the absence of activity against Gram-negative rods is related, among other things, to the extrusion of these compounds from bacterial cells by multi-drug resistance efflux pumps. Substrates for the resistance-nodulation-division efflux systems include the following non-antibiotics: salicylate, diclofenac, ibuprofen, mefenamic acid, naproxen, amitriptyline, alendronate sodium, nicergoline, and ticlopidine. In addition, interactions between non-antibiotics and multi-drug resistance efflux pumps have been observed. It has also been revealed that depending on the concentration, salicylate induces expression of multi-drug resistance efflux pumps in Escherichia coli, Salmonella enterica subsp. enterica serotype Typhimurium, and Burkholderia cenocepacia. However, salicylate does not affect the expression of the resistance-nodulation-division efflux systems in Stenotrophomonas maltophilia and Acinetobacter baumannii. Most importantly, there were no effects of medicinal products containing some non-antibiotic active substances, except salicylate, as substrates of multi-drug resistance efflux pumps, on the induction of Gram-negative rod resistance to quinolones.

Abstract
Background: There is little evidence in the literature on the association between methylphenidate treatment and psychotic symptoms in children and adolescents with attention-deficit/hyperactivity disorder (ADHD).
Objective: We examine the occurrence of psychotic symptoms during methylphenidate treatment of children and adolescents with ADHD. The data arise from our two Cochrane systematic reviews on methylphenidate, reported elsewhere.
Methods: Electronic databases were searched up to January 2016 (for observational studies) and March 2017 (for randomized trials). We summarized data as risk ratios and pooled prevalences. Trial Sequential Analysis was used to control for random errors. We assessed the risk of bias and the quality of evidence according to Cochrane guidelines.
Results: Ten randomized trials (1103 participants), 17 non-randomized studies (76,237 participants) and 12 patient reports or series (18 patients) were identified. In the randomized trials, there was no significant difference in the risk of developing psychotic symptoms [10 of 654 (pooled prevalence, 2.5%) methylphenidate versus 1 of 508 (pooled prevalence, 1.7%) placebo patients; risk ratio, 2.07; 95% confidence interval, 0.58 to 7.35]. Nine of 10 trials had a high risk of bias, and according to the Trial Sequential Analysis, the required information size was not achieved, that is, the meta-analysis was considerably underpowered. There were 873 instances of psychotic symptoms in the non-randomized studies among 55,603 participants (pooled prevalence, 1.2%; 95% confidence interval, 0.7 to 2.4). In the comparative cohort study, methylphenidate significantly increased the risk for any psychotic disorder by 36% (risk ratio, 1.36; 95% confidence interval, 1.17 to 1.57). The overall risk of bias was rated as critical for this study.
Conclusions: Because of sparse data and low quality of evidence, we cannot confirm or refute whether methylphenidate increases the risk of psychotic symptoms in children and adolescents with ADHD. This possible adverse event may affect 1.1% to 2.5%, and physicians, patients and caregivers should be aware of this to ensure proper treatment in case of occurrence during methylphenidate treatment.
A BAYESIAN INFERENCE OF MULTIPLE STRUCTURAL BREAKS IN MEAN AND ERROR VARIANCE IN PANELAR (1) MODEL
Authors: Agiwal Varun , Kumar Jitendra , Shangodoyin Dahud Kehinde 
Published: June 2018

Abstract
This paper explores the effect of multiple structural breaks to estimate the parameters and test the unit root hypothesis in panel data time series model under Bayesian perspective. These breaks are present in both mean and error variance at the same time point. We obtain Bayes estimates for different loss function using conditional posterior distribution, which is not coming in a closed form, and this is approximately explained by Gibbs sampling. For hypothesis testing, posterior odds ratio is calculated and solved via Monte Carlo Integration. The proposed methodology is illustrated with numerical examples.
JOINT RESPONSE PROPENSITY AND CALIBRATION METHOD
Authors: Laaksonen Seppo , Hämäläinen Auli 
Published: June 2018

Abstract
This paper examines the chain of weights, beginning with the basic sampling weights for the respondents. These were then converted to reweights to reduce the bias due to missing quantities. If micro auxiliary variables are available for a gross sample, we suggest taking advantage first of the response propensity weights, and then of the calibrated weights with macro (aggregate) auxiliary variables. We also examined the calibration methodology that starts from the basic weights. Simulated data based on a real survey were used for comparison. The sampling design used was stratified simple random sampling, but the same methodology works for multi-stage sampling as well. Eight indicators were examined and estimated. We found differences in the performance of the reweighting methods. However, the main conclusion was that the response propensity weights are the best starting weights for calibration, since the auxiliary variables can be more completely exploited in this case. We also tested problems of calibration methods, since some weights may lead to unacceptable weights, such as below 1 or even negative.

Published: June 2018

Surface runoff and tile drainage are the main pathways for water movement and entry of agricultural nitrate into water resources. The objective of this 5‐yr study was to characterize the partitioning of water flow and nitrate loss between these pathways for a humid‐temperate Brookston clay loam soil under 54 to 59 yr of consistent cropping and fertilization. Cropping treatments included monoculture corn (Zea mays L., MC), continuous bluegrass (Poa pratensis L.) sod (CS), and a corn–oat–alfalfa (Medicago sativa L.)–alfalfa rotation (RC–RO–RA1–RA2). Fertilization treatments included annual fertilizer addition (F) and no fertilizer addition (NF). Tile drainage and surface runoff occurred primarily during the nongrowing season (November–April), and they were highly correlated with the mean saturated hydraulic conductivity of the near‐surface soil profile. Tile drainage accounted for 69 to 90% of cumulative water flow and 79 to 96% of cumulative nitrate loss from fertilized rotation and CS, whereas surface runoff accounted for the majority of the nitrate losses in MC (i.e., 75–93% of water flow and 65–96% of nitrate loss). Cumulative nitrate losses were highest in the RC‐F (152 kg N ha−1), RC‐NF (101 kg N ha−1), RA2‐F (121 kg N ha−1), and RA2‐NF (75 kg N ha−1) plots, and these high losses are attributed to N mineralization from the plowed alfalfa and fertilization (if applicable). Fertilization increased cumulative nitrate loss in tile drainage from all treatments, whereas no fertilization increased cumulative nitrate loss in surface runoff from the rotation. Cropping system and fertilization on clay loam soil changed how water flow and nitrate loss were partitioned between tile drainage and surface runoff.Core Ideas
Water partitioning is highly correlated with mean saturated hydraulic conductivity.
Tile drainage was the main pathway of water flow and nitrate loss in rotation plots.
Surface runoff was the main pathway of water flow and nitrate loss in monoculture corn.
Fertilization increased nitrate loss and water flow through tile drainage.
Average nitrate loss was 36% greater in the rotation plots versus monoculture corn.

Los derechos humanos y los sociales, susceptibles de permanente reinvención: una mirada innovadora desde el presente en sintonía con el pasado.
Authors: Lacalzada-de-Mateo María José 
Published: June 2018

Es conocido que el Trabajo social defiende la autonomía de la persona y favorece la inclusión en el medio, mejorando sus oportunidades. La palabra “innovación” hoy adquiere protagonismo en la intervención, en particular, y para la estructuración de los Estados y las relaciones políticas, en general. Los Derechos Humanos y su derivación en sociales arrostran tales dificultades, tales presiones estructurales, que quienes los defienden han de mantener una actitud que parezca innovadora. Es la clave con la que se presupone credibilidad dentro del culto a lo inmediato que nos envuelve hoy. Defender los derechos de las personas es recoger un testigo humanizador que toma por referente la dignidad humana. Siempre que se ha tenido esta actitud han mejorado las relaciones en sociedad. Está en el fundamento de los Estados de Bienestar, estableciendo reglas que han mejorado el acceso al reparto de las riquezas, objetivando normas y derechos en el espacio público. Si nos situamos historiográficamente en el siglo XIX encontraremos una perspectiva que fue reformadora e innovadora en el pasado y que mantiene su fuerza revolucionaria en el presente: ajustar el ángulo de visión desde la dignidad y sentido integral de la persona humana. Discurrir así, tiene capacidad para mejorar las intervenciones y para objetivar normas para hacer viable la justicia social y con ello orientar la práctica del Trabajo Social hacia la promoción de las personas y colectivos más vulnerables de la sociedad. Llevaremos la atención sobre esta forma de discurso que recoge cierto legado humanista que encamina a construir un mundo más sostenible.
