Farmers' preferences for livestock pollution control policy in China: a choice experiment method

Using a survey data of 754 pig breeders in China, the choice experiment method was employed to investigate farmers' preferences for livestock pollution control policy. Five attributes technical support, pollution fees, technical standards, biogas subsidies, and the manure market were set as parameters of a study of livestock pollution control policies. A random parameter logit model was used, which considered the heterogeneity of the farmers' preferences. The main results are as follows: (i) the biogas subsidy, technical support, pollution fees and manure market were shown to be significant factors of preference over alternative policy designs in terms of incremental changes in environmentally friendly manure handling; (ii) heterogeneity was observed in farmers' preferences for livestock pollution control policies. Farmers' choices of improved pollution policy options were significantly influenced by their education, the size of their farms and their willingness to treat pollution; (iii) farmers showed the highest preferences for a biogas subsidy policy, followed (in this order) by a high technical support policy, a pollution fee policy, a medium technical support policy, a manure market policy and finally a technical standard policy.
Calibration strategy of diesel fuel spray atomization models using a design of experiment method

The Reitz and Diwakar and the KHRT atomization models are widely used for high pressure diesel fuel spray. The constants in both models must be calibrated to correctly predict the injection process based on the nozzle geometry, injection conditions, and fuel. Calibration can be significantly time consuming given the four constants in both models. This paper suggests a strategy to assess the impact of models' constants on spray tip penetration and mean droplet diameter predictions on a reference case, with an injection pressure of 700 bar, to characterize the influence of the atomization model's calibration. The assessment used a design of experiment method (DOE) which demonstrated the important interaction between constants on the results. Obtained calibrations were used for comparing the models' performances qualitatively and quantitatively by accounting for spray and air entrainment characteristics. Both models gave similar results, but the KHRT model yielded a better spray shape. Finally, based on DOE results, a method is proposed to modify the model's constants for higher pressures (900 and 1300 bar)
Optimization of spring back in creep age forming process of 7075 Al Alclad alloy using D optimal design of experiment method

This paper attempts to model and predict the spring back for creep age forming of a 7075 Al Alclad alloy using statistical analyses based on a design of experiments method. Time and temperature were chosen as effective variables for determining spring back in the creep age forming process. The D optimal design of experiments method facilitated statistical analyses and the extraction of a mathematical model for determining spring back in the experimental variables domain. The spring back of the specimens was calculated using a numerical procedure based on the pure bending theory. Analysis of the variances for spring back showed that temperature was the most effective variable in the creep age forming process. Additionally, a mathematical model and the response surface of the spring back showed that to decrease spring back, the significant variables should be in the upper level. The spring back in the creep age forming process was optimized for a 7075 Al Alclad alloy in the optimum mechanical properties region.

A multicriteria model on calculating the Sustainable Business Excellence Index of a firm with fuzzy AHP and TOPSIS

The purpose of this paper is to provide an integrated methodology for benchmarking the sustainability of organizations. The fuzzy analytical hierarchy process (FAHP) and technique for order of preference by similarity to ideal solution (TOPSIS) methods have been used for this purpose. The FAHP is used to determine the weights of the criteria by decision makers, and the rankings of the alternatives are determined by TOPSIS. The proposed instrument is used to calculate the Sustainable Business Excellence Index (SBEI) and its potential impact on the formulation of firm strategy. To demonstrate the applicability of the model, illustrative examples are presented.  After a careful literature review, a sustainable business excellence framework is created and a fuzzy system is developed to assess firms' sustainability. Finally, the SBEI is computed.  The results indicate that the suggested fuzzy approach is feasible for benchmarking the sustainability of organizati.
A domain agnostic approach for opinion prediction on speech
Venue: PEOPLES@COLING

We explore a domain agnostic approach for analyzing speech with the goal of opinion prediction. We represent the speech signal by mel frequency cepstral coefficients and apply long short term memory neural networks to automatically learn temporal regularities in speech. In contrast to previous work, our approach does not require complex feature engineering and works without textual transcripts. As a consequence, it can easily be applied on various speech analysis tasks for different languages and the results show that it can nevertheless be competitive to the state of the art in opinion prediction. In a detailed error analysis for opinion mining we find that our approach performs well in identifying speaker specific characteristics, but should be combined with additional information if subtle differences in the linguistic content need to be identified.

A full polarization arbitrary shaped 3D metasurface cloak with preserved amplitude and phase in microwave frequencies is experimentally demonstrated. By taking the unique feature of metasurfaces, it is shown that the cloak can completely restore the polarization, amplitude, and phase of light for full polarization as if light was incident on a flat mirror.
Use of 3D printed models in medical education: A randomized control trial comparing 3D prints versus cadaveric materials for learning external cardiac anatomy
Venue: Anatomical sciences education

Three dimensional (3D) printing is an emerging technology capable of readily producing accurate anatomical models, however, evidence for the use of 3D prints in medical education remains limited. A study was performed to assess their effectiveness against cadaveric materials for learning external cardiac anatomy. A double blind randomized controlled trial was undertaken on undergraduate medical students without prior formal cardiac anatomy teaching. Following a pre test examining baseline external cardiac anatomy knowledge, participants were randomly assigned to three groups who underwent self directed learning sessions using either cadaveric materials, 3D prints, or a combination of cadaveric materials/3D prints (combined materials) Participants were then subjected to a post test written by a third party. Fifty two participants completed the trial; 18 using cadaveric materials, 16 using 3D models, and 18 using combined materials. Age and time since completion of high school were equally distributed between groups. Pre test scores were not significantly different (P 0.231) however, post test scores were significantly higher for 3D prints group compared to the cadaveric materials or combined materials groups (mean of 60.83% vs. 44.81% and 44.62% P 0.010, adjusted P 0.012) A significant improvement in test scores was detected for the 3D prints group (P 0.003) but not for the other two groups. The finding of this pilot study suggests that use of 3D prints do not disadvantage students relative to cadaveric materials; maximally, results suggest that 3D may confer certain benefits to anatomy learning and supports their use and ongoing evaluation as supplements to cadaver based curriculums.  213 221.
History of cardiac anatomy: A comprehensive review from the egyptians to today
Venue: Clinical anatomy

The nature, function, and anatomy of the heart have been extensively studied since 3500 B.C. Greek and Egyptian science developed a basic understanding of the heart, although this was primarily related to religious beliefs. During the Hippocratic era, Hippocrates and his colleagues developed a more scientific and less religious understanding of the cardiovascular system. The post Hippocratic era was characterized by more advanced descriptions of the location, structure, and function of the heart. The Alexandrian, Roman, Medieval Islamic, and European eras included turning points in the history of cardiac anatomy. Subsequently, after the structure and function of the heart were established, its connection with the lungs was investigated. Description of the pulmonary circulation was followed by the discovery of the conductive system and innervation of the heart.  2016.
3D BUILDING RECONSTRUCTION BY MULTIVIEW IMAGES AND THE INTEGRATED APPLICATION WITH AUGMENTED REALITY

This study presents an approach wherein photographs with a high degree of overlap are clicked using a digital camera and used to generate three dimensional (3D) point clouds via feature point extraction and matching. To reconstruct a building model, an unmanned aerial vehicle (UAV) is used to click photographs from vertical shooting angles above the building. Multiview images are taken from the ground to eliminate the shielding effect on UAV images caused by trees. Point clouds from the UAV and multiview images are generated via Pix4Dmapper. By merging two sets of point clouds via tie points, the complete building model is reconstructed. The 3D models are reconstructed using AutoCAD 2016 to generate vectors from the point clouds; SketchUp Make 2016 is used to rebuild a complete building model with textures. To apply 3D building models in urban planning and design, a modern approach is to rebuild the digital models; however, replacing the landscape design and building distribution in real time is difficult as the frequency of building replacement increases. One potential solution to these problems is augmented reality (AR) Using Unity3D and Vuforia to design and implement the smartphone application service, a markerless AR of the building model can be built. This study is aimed at providing technical and design skills related to urban planning, urban designing, and building information retrieval using AR.
Driven neutron star collapse: Type I critical phenomena and the initial black hole mass distribution

We study the general relativistic collapse of neutron star (NS) models in spherical symmetry. Our initially stable models are driven to collapse by the addition of one of two things: an initially in going velocity profile, or a shell of minimally coupled, massless scalar field that falls onto the star. Tolman Oppenheimer Volkoff (TOV) solutions with an initially isentropic, gamma law equation of state serve as our NS models. The initial values of the velocity profile's amplitude and the star's central density span a parameter space which we have surveyed extensively and which we find provides a rich picture of the possible end states of NS collapse. This parameter space survey elucidates the boundary between Type I and Type II critical behavior in perfect fluids which coincides, on the subcritical side, with the boundary between dispersed and bound end states. For our particular model, initial velocity amplitudes greater than 0.3c are needed to probe the regime where arbitrarily small black holes can form. In addition, we investigate Type I behavior in our system by varying the initial amplitude of the initially imploding scalar field. In this case we find that the Type I critical solutions resemble TOV solutions on the 1 mode unstable branch of equilibrium solutions, and that the critical solutions' frequencies agree well with the fundamental mode frequencies of the unstable equilibria. Additionally, the critical solution's scaling exponent is shown to be well approximated by a linear function of the initial star's central density.
Visible light activated oxygen rich TiO2 as next generation photocatalyst: Importance of annealing temperature on the photoactivity toward reduction of carbon dioxide

Herein, visible light active oxygen rich TiO 2 (O 2 TiO 2 photocatalysts were synthesized via a facile and dopant free strategy using different annealing temperatures ranging from 200 to 800 degC. The annealing treatment had important effects on the anatase rutile phase composition, textural property and photocatalytic performance of O 2 TiO 2 The photoactivity of the samples were evaluated through the photocatalytic reduction of CO 2 under the irradiation of low powered energy saving daylight bulbs. O 2 TiO 2 calcined at an optimum temperature of 300 degC (O 2 TiO 2 300) displayed the highest photocatalytic performance, achieving an enhancement factor of 12.2 and 11.2 over pure anatase TiO 2 and the commercial Degussa P25, respectively. Although the improvement in photoactivity could be attributed to the combined effect of several factors such as enhanced optical properties and high surface area of O 2 TiO 2 300, the findings from this work provided evidence that the optimum anatase rutile phase composition in the sample played a dominant role in the enhancement of photocatalytic performance. Based on the experimental results obtained, a plausible mechanism for the charge transfer and separation process in O 2 TiO 2 was also proposed. The present work could provide new insights into the architecture of oxygen modified TiO 2 photocatalysts with markedly enhanced photocatalytic activities in energy and environmental related applications.
Rating Scale Format and Item Sensitivity to Response Style in Large Scale Assessments

This study examines the relationship between rating scale format and instrument sensitivity to response style (RS) A multidimensional nominal response model (MNRM) that allows item discrimination to vary across items for both substantive and RS dimensions can be used for this purpose. We first conduct a set of simulations to examine the recovery of item slopes under the model. Then we apply the model to PISA and PIRLS survey items to investigate the item sensitivity to RS in relation to different rating scale types. Simulation results indicate good recovery of item slopes on both substantive and RS traits, and different rating scale formats (agreement type versus frequency type scales) from PISA and PIRLS are found to have varying sensitivities to RS, such that frequency type scales are less affected.
The Influence of Rewards on Employees Performance

The study aims to examine the influence of reward types (extrinsic, intrinsic, social and rewards mix) on employees performance. Subjects for the study consisted of 308 workers which constituted 60% of the total target population of 513 people working for Unified Mining Companies located in the southern part of Jordan. Total of 308 self designed questionnaire were distributed to employees on their job location, 268 questionnaires were returned and only 250 were suitable for statistical analysis.  16 has been used for data analysis. Both descriptive and inferential statistics were used for data analysis. The statistical tools were aligned with the objective of the research. For this purpose, frequency Tables, percentages, means and standard deviations were computed and substantively interpreted. Inferential statistics like Pearson product moment correlation coefficient (r) was used to determine if there is a significant relationship exist between independent variables (rewards types: Extrinsic, intrinsic, social and rewards mix) and dependent variable (employees performance) Analysis and interpretation were made at 0.05 level of significance. The findings indicated that there is a statistical significant relationship between rewards types and employees performance. The study has concluded that, management should have deep sense of commitment towards the issue of rewarding employees, if performance levels to be enhanced. Finally, future research can be conducted to cover all types of rewards and to determine their affect on performance.

Continuous wound infiltration versus epidural analgesia after hepato pancreato biliary surgery (POP UP) a randomised controlled, open label, non inferiority trial.
Venue: The lancet. Gastroenterology hepatology

Epidural analgesia is the international standard for pain treatment in abdominal surgery. Although some studies have advocated continuous wound infiltration with local anaesthetics, robust evidence is lacking, especially on patient reported outcome measures. We aimed to determine the effectiveness of continuous wound infiltration in hepato pancreato biliary surgery.  In this randomised controlled, open label, non inferiority trial (POP UP) we enrolled adult patients undergoing hepato pancreato biliary surgery by subcostal or midline laparotomy in two Dutch hospitals. Patients were centrally randomised (1:1) to receive either pain treatment with continuous wound infiltration using bupivacaine plus patient controlled analgesia with morphine or to receive (patient controlled) epidural analgesia with bupivacaine and sufentanil. All patients were treated within an enhanced recovery setting. Randomisation was stratified by centre and type of incision. The primary outcome was the mean Overall Benefit of Analgesic Score (OBAS) from day 1 5, a validated composite endpoint of pain scores, opioid side effects, and patient satisfaction (range 0 [best] to 28 [worst] Analysis was per protocol. The non inferiority limit of the mean difference was 3*0.   Between Jan 20, 2015, and Sept 16, 2015, we randomly assigned 105 eligible patients: 53 to receive continuous wound infiltration and 52 to receive epidural analgesia. One patient in the continuous wound infiltration group discontinued treatment, as did five in the epidural analgesia group; of these five patients, preoperative placement failed in three (these patients were treated with continuous wound infiltration instead) one patient refused an epidural, and data for the primary endpoint was lost for one. Thus, 55 patients were included in the continuous wound infiltration group and 47 in the epidural analgesia group for the per protocol analyses. Mean OBAS was 3*8 (SD 2*4) in the continuous wound infiltration group versus 4*4 (2*2) in the epidural group (mean difference 0*62, 95% CI 1*54 to 0*30) Because the upper bound of the one sided 95% CI did not exceed +3*0, non inferiority was shown. Four (7% patients in the continuous wound infiltration group and five (11% of those in the epidural group had an adverse event. One patient in the continuous wound infiltration group had a serious adverse event (temporary hypotension and arrhythmia after bolus injection) no serious adverse events were noted in the epidural group.  These data suggest that continuous wound infiltration is non inferior to epidural analgesia in hepato pancreato biliary surgery within an enhanced recovery setting. Further large scale trials are required to make a definitive assessment of non inferiority.

A General Framework for Content enhanced Network Representation Learning
Venue: ArXiv

This paper investigates the problem of network embedding, which aims at learning low dimensional vector representation of nodes in networks. Most existing network embedding methods rely solely on the network structure, i.e. the linkage relationships between nodes, but ignore the rich content information associated with it, which is common in real world networks and beneficial to describing the characteristics of a node. In this paper, we propose content enhanced network embedding (CENE) which is capable of jointly leveraging the network structure and the content information. Our approach integrates text modeling and structure modeling in a general framework by treating the content information as a special kind of node. Experiments on several real world net works with application to node classification show that our models outperform all existing network embedding methods, demonstrating the merits of content information and joint learning.
