Computational Analysis to Reduce Classification Cost Keeping High Accuracy of the Sparser LPSVM

728 Abstract—Vapnik’s quadratic programming (QP)-based support vector machine (SVM) is a state-of-the-art powerful classifier with high accuracy while being sparse. However, moving one step further in the direction of sparsity, Vapnik proposed another SVM using linear programming (LP) for the cost function. This machine, compared with the complex QPbased one, is sparser but poses similar accuracy, which is essential to work on any large dataset. Nevertheless, further sparsity is optimum for computational savings as well as to work with very large and complicated datasets. In this paper, we accelerate the classification speed of Vapnik’s sparser LPSVM maintaining optimal complexity and accuracy by applying computational techniques generated from the “unity outward deviation (ζ)”—analysis of kernel computing vectors. Benchmarking shows that the proposed method reduces up to 63% of the classification cost by Vapnik’s sparser LPSVM. In spite of this massive classification cost reduction, the proposed algorithm poses classification accuracy quite similar to the stateof-the-art and most powerful machines, for example, Vapnik’s QPSVM or Vapnik’s LPSVM while being very simple to realize and applicable to any large dataset with high complexity.
Combining academia and activism

Academics can engage in and contribute to activism in various ways. Some are involved in action groups on issues such as climate change and treatment of asylum seekers. Some undertake research and speak to the media about indigenous, environmental, gender and other issues. Others campaign on matters of concern within universities, including through unions and professional associations. Other possibilities include undertaking research that informs or supports activism, and advising and supporting activist students. These and other forms of academic activism can be risky. Academics who seek to combine activism with work in the university can be subject to threats, abuse, silencing tactics, and peer pressure and scholarly expectations to shift away from activism. In this paper we explore these obstacles with an emphasis on strategies for avoiding the pitfalls and maintaining commitment as an activist-oriented academic. Drawing on our diverse experiences of activism, academia and communityengaged research, we suggest possible responses to the many pressures on activist academic work, paying particular attention to the challenges faced by early career academics. Academia can be a site for activism in at least four ways (Downs & Manion, 2004; Zerai, 2002): (1) as a means to produce knowledge to inform progressive social change; (2) as a means for conducting research which itself involves social change; (3) as a site for progressive strategies of teaching and learning; and finally (4) as an institution whose power relations themselves may be challenged and reconstructed. (See Ward (2007) for another framework of approaches to academia and activism, highlighting activist, participatory and policy geographies. These share an ideological commitment to social and personal change but differ in terms of whether they see themselves as working as, with, or for particular publics respectively. ) We briefly review the nexus of academia and activism before offering strategies for combining them. First, academics may produce knowledge that, intentionally or not, informs progressive social change. Academic research may be taken up by activist and advocacy organisations for their own campaign work. Academics may contribute to policy debates and political change by participating in public debate or by direct submissions to policymakers. Second, academics’ conduct of research itself may involve social change. The term ‘action research’ describes a family of research methodologies that involve simultaCombining academia and activism
Biting behavior of multiparous female of Anopheles gambiae s. s. and transmission of Plasmodium falciparum in South-Eastern of Benin

Background: The Plasmodium falciparum transmission occurs mainly at night. Anopheles mosquitoes that transmit P. falciparum are those that have taken blood feed and laid eggs several times. Unfortunately, the biting behavior of these mosquitoes is little known. This study aims to assess the impact of the biting behavior of multiparous vectors on malaria transmission. Methods: Mosquitoes were collected by hour from 21. 00 hours to 05. 00 hours in two villages, Abomey-Takplikpo and Itassoumba, south-easten Benin. Anopheles gambiae s.l. was morphologically identified and dissected using the method of Polovodova and oil injection technique. The head-thoraces were assessed using enzyme-linked immunosorbent assay (ELISA CSP) and the others body parts were used for molecular identification by Polymerase Chain Reaction (PCR). Results: Among the parous An. gambiae s.l. collected at Abomey-Takplikpo and Itassoumba, old An. gambiae s.l. that laid eggs several times bite more frequently in the second half of the night (p<0.05) than young An. gambiae s.l. that were more likely to bite earlier in the houses. On the 1008 and 868 headthoraces of An. gambiae s.s. confirmed by PCR and analyzed by the ELISA-CSP respectively at Itassoumba and AbomeyTakplikpo, 2.98% (n = 30) and 2.53% (n = 22) were tested positive for the circumsporozoitic antigen of P. falciparum. Overnight, the infectivity distribution is homogeneous in both localities (P> 0.05). However, in the second half of the night, infectious mosquitoes were more frequent. At Itassoumba and Abomey-Takplikpo, the biting behavior of multiparous females explains respectively 89.51% (R2 = 0.8951) and 90.17% (R2 = 0.9017) of the variability of mosquitoes’ infectivity. Conclusion: Young Anopheles gambiae s.s. bite earlier in houses than old An. gambiae s.s. that bite more in the second half of the night. Infectious An. gambiae s.s. bite at any time of the night but more frequent after midnight. In addition, the biting behavior of multiparous An. gambiae s.s. was significantly associated with P. falciparum transmission.
Motivational Techniques for Teaching: Prophetic Model

In recent years, teaching has become a challenging activity due to modernization and globalization. Teachers exercise a variety of modern motivational techniques to deliver knowledge in educational institutes. Motivation is considered a central key in the process of teaching and learning. The present study aims to explore pedagogical motivational techniques used and lived by the Prophet Muhammad (pbuh stands for peace be upon him) for teaching and education. Essentially, the personality of the Prophet (pbuh) was a pinnacle of teaching philosophy and educating. The present study is articulated employing an analytical review of some authentic traditions of the Prophet (pbuh) to address these motivational techniques. The findings reveal that his motivational techniques for teaching and educating are likely to use in the promotion of appropriate teaching and learning. The Prophet? s motivation methodology is monotheistic centric (tawhidi centric) with a high goal by addressing to the heart, mind and soul. It is in the peak level of perfection (ihsan). With applying such methodology, he made the most primitive and illiterate of peoples into the masters and teachers of the world in 23 years. Adhering to Prophetic motivational techniques for teaching and educating, teachers may play a more useful role in educational institutes. Overall, this study serves as a gateway for Muslim teachers and instructors to be effective in teaching and educating activities as well as researchers, educationists, and scholars to be motivated in exploring the personality of the Prophet (pbuh) as a universal teacher and educator.
Insider Activism ∗

We show that inside shareholders use activist tactics to influence firm policies, which we term insider activism. We contrast insider activism with hedge fund activism and find that insider activists have larger stakes in the firm, employ more aggressive tactics, and are more likely to seek board representation or control. The targets of insider activism differ from those of hedge fund activists. Insider activist campaigns are less successful than hedge fund activist campaigns in meeting their objectives, but they are associated with improvements in value and operating performance. Our analysis therefore suggests that insider activism is an effective governance mechanism that plays a distinct and complementary role. ∗We are grateful to Nick Gantchev, Hong Zhao and conference and seminar participants at the 2016 Arizona Junior Finance Conference and the University of New South Wales for helpful comments.

Institutional Adoption of a Learning Management System in Higher Education: A Case Study of the Corvinus University in Budapest

The development of the Moodle e-learning system started in 2002. Since it is an open source platform with a prominently rich functionality, the system has been introduced in more than 100,000 organisations3 worldwide in the last decade, including numerous Hungarian higher education institutions (Szent István University, Óbuda University, University of Pannonia) and many organisations in the public administration. We have been operating with one of the largest user (12,000 visitors daily) and course (more than 1,000 active courses per semester) numbers in Hungary, a Moodle based system since 2007 at the Corvinus University of Budapest (CUB) with a high level of user satisfaction. We managed a major, overall system improvement project at CUB in 2016. The development included a version upgrade to the newest Moodle 3, a full redesign, introduction of several new functions regarding the professors’ needs and core improvement on the system’s stability and security among others with a comprehensive load-impact test. In this paper, we discuss the success factors and pitfalls of the whole renewal process. We will further focus on analysing the group discussions with the major stakeholders and evaluate the comprehensive load-impact test. At the end of our paper, we will examine the state of the Moodle e-learning system at the National University of Public Service and we will propose elements of an improvement project relying on our recent experience at another university.
The Relations between Student Cynicism and Students’ Life Satisfaction

The purpose of this study is to determine the relationship between student cynicism and students’ life satisfaction. This study is in correlational survey model. The sample of the study consists of 554 Turkish high school students, who were selected by simple random sampling method. Findings show that female students have more cynical attitudes towards their schools than male students. And, female students are less satisfied with their school and living environment but more satisfied with their friends than male students. Students who think about studying at another school have higher levels of student cynicism but lower levels of school satisfaction and living environment satisfaction than those who do not think so. The findings reveal the negative relationships between student cynicism and students’ life satisfaction. The strongest relationship has been determined to be between institutional cynicism and reduced sense of school satisfaction. Path analysis indicates that four subscales of student cynicism affect students’ life satisfaction. It is possible to examine the premises that lead to the perception of student cynicism and their impacts. For future research, it is recommended to examine the ways to alleviate the negative effects of student cynicism and improve the outcomes.
Public Images of Dairy Farms among Urban Dwellers in Bogotá, Colombia

This study explores the public images of dairy farms among urban dwellers in Bogota, Colombia. For the study, d esigned as an explorative case study, 30 participants were interviewed using a triangulated research method including a word association task, a drawing exercise, and a semi -structured interview. Public images reflected traditional dairy farms and were constructed through personal experiences with peasants and traditional manors. Product choice was based on health and hygiene, associated with modern dairy farms. Yet, modernization was argued to threaten animal welfare, the environment, and peasant livelihoods. To ensure socio-cultural sustainability, traditional production systems need to be better integrated into the modernization process.
An Analysis of the Stock Price Impact on the TSE and Accrual Management

This study examined the role of positive and negative discretionary accrual management in the stock price impact. A sample of 66 firms listed in Tehran Stock Exchange was selected for a ten-year period (2008-2017). Accrual management was found to lead to significant changes in stock prices, and uninformed investors incur trading costs caused by the stock price impact. The results showed two key points. First, the mispricing of discretionary accrual components in the market leads to an increase in the stock price impact, and second, the management of positive discretionary accruals has a greater effect on stock price impacts than negative discretionary accruals. Using positive discretionary accruals, investors overvalue the firm and engage in trading stocks. Due to the mispricing of positive discretionary accruals, an asymmetric behavior is formed in the stock price impact.
Effects of Light Emitting Diode (LED) Spectra on the Expression of Vertebrate Ancient Long Opsin Gene and Maturation-related Hormones in the Goldfish, Carassius auratus

This study was investigated the effect of light spectra on vertebrate ancient long opsin (VAL-opsin) and sex hormones in the goldfish, Carassius auratus using red and green light-emitting diodes (LEDs). In addition, this study was investigated the effect of in vivo injection of exogenous gonadotropin hormone (GTH; 5 μg/g body weight) on VAL-opsin levels. It was measured changes in the expression levels of gonadotropin-releasing hormone (GnRH: sGnRH and cGnRH-II), GTHs (GTH: GTH , LH , and α β FSH ), β and estrogen receptor (ER: ER , ER 1, and ER 2) mRNAs, and α β β GnRH and GTH proteins. Furthermore, it was measured changes in plasma 17 -estradiol (E β 2) levels. In fish exposed to green light spectra and 5 μg/g GTH injection, VAL-opsin levels were significantly higher than the control (white) and red light-exposed groups. In fish exposed to green light spectra, the expression levels of GnRHs, ERs, and plasma E2 were significantly higher than those of the control and red light-exposed groups (P < 0.05).
Utilization of cauliflower (Brassica oleracea L. ssp. botrytis) stem flour in improving Balady bread quality

This study was designed to evaluating the use of cauliflower stems flour (CSF) as partial substitution of wheat flour (WF) at levels of 5, 10 ,15 and 20% in Egyptian Balady bread making on farinograph and extensograph properties of the produced doughs, also organoleptic properties, freshness and chemical composition of the produced bread which compared to control wheat bread. Farinograph results showed that as CSF substitution level increased the water absorption and dough weakening increased whereas the mixing time and dough stability were decreased. On the other hand, results of extensograph showed that the dough energy, the resistance to extension, dough extensibility and the proportional number were decreased with increasing CSF level. On the other side, the organoleptic evaluation showed that the substitution of wheat flour with CS Fat level5 % produce bread similar to the control sample (wheat bread) in all organoleptic properties. Regarding the chemical composition of produced bread, a gradually increase was observed in protein, ether extract, crude fiber and ash contents with increasing the level of added CSF as compared with control bread. Also, results indicated that the cauliflower stems flour improved the bread freshness. It could be concluded that the cauliflower flour can be used to replace 5% to 10% of wheat flour in Balady bread making without adverse effect on the consumer acceptability of the bread.
Comparison of Different Types of Fitness Functions to Choose the Appropriate Attributes for Porosity Prediction

Porosity is one of the most important reservoir characteristics because it indicates to fluid collection. Several techniques used to get good porosity prediction, so, in this study we employed seismic attributes and well log data in a genetic algorithm to get the best porosity prediction. The study attempt to enhance the performance of genetic algorithm for attribute selection and therefore porosity prediction by applying genetic algorithm on different types of fitness functions like average mean square error fitness, average correlation coefficients fitness and performance index fitness. Also, used two methods to represent attributes in genetic algorithm. Different witnesses applied to choose the appropriate fitness function that gives high porosity prediction.
The Impact of Plant Clinics on the Livelihoods of Bangladeshi Farmers

The Plantwise programme in Bangladesh was launched in 2015 to build local capacity in plant pest and disease management to enable frontline extension workers to provide practical recommendations to farmers. We assessed the impact of plant clinics on farm productivity and profitability with a focus on cucurbits with fruit fly. A quasi-experimental approach was taken, with a matching design, based on similarity of agro-ecological zone, crops grown and pests and diseases. Results showed an increase in income for plant clinic users growing all types of cucurbits.
How to Survive in Academia: Demands, Resources and Study Satisfaction Among Polish PhD Students

There is a great deal of research showing that PhD students suffer from dissatisfaction. Whereas most studies in this field strived to identify factors negatively related to PhD students’ well-being, still little is known about factors positively related to the well-being of young academics. We based our analysis on the Job Demands-Resource Theory (JD-R), to identify study resources positively related to PhD student satisfaction. Building on the results of the survey conducted among 360 PhD students of the Jagiellonian University (Poland) we singled out seven main resources most strongly related to PhD student satisfaction. Our findings might provide initial evidence about what type of resources are worth developing to maximize PhD student well-being. These results could be of particular importance and interest for candidates who look for PhD positions and PhD students already working in different academic environments, as well as for broader academic community and higher education policymakers.
Cloud_cci ATSR-2 and AATSR dataset version 3: a 17-yearclimatology of global cloud and radiation properties

Abstract. We present version 3 (V3) of the Cloud_cci ATSR-2/AATSR dataset. The dataset was created for the European Space Agency (ESA) Cloud_cci (Climate Change Initiative) program. The cloud properties were retrieved from the second Along- Track Scanning Radiometer (ATSR-2) on board the second European Remote Sensing Satellite (ERS-2) spanning 1995–2003 and the Advanced ATSR (AATSR) on board Envisat, which spanned 2002–2012. The data comprises a comprehensive set of cloud properties: cloud top height, temperature, pressure, spectral albedo, cloud effective emissivity, effective radius and optical thickness alongside derived liquid and ice water path. Each retrieval is provided with its associated uncertainty. The cloud property retrievals are accompanied by high-resolution top and bottom-of-atmosphere short- and long-wave fluxes that have been derived from the retrieved cloud properties using a radiative transfer model. The fluxes were generated for all-sky and clear-sky conditions. V3 differs from the previous version 2 (V2) through development of the retrieval algorithm and attention to the consistency between the ATSR-2 and AATSR instruments. The cloud properties show improved accuracy in validation and better consistency between the two instruments, as demonstrated by a comparison of cloud mask and cloud height with collocated CALIPSO data. The cloud masking has improved significantly, particularly the ability to detect clear pixels The Kuiper Skill score has increased from . 49 to . 66. The cloud top height accuracy is relatively unchanged. The AATSR liquid water path was compared with the Multisensor Advanced Climatology of Liquid Water Path (MAC-LWP) in regions of stratocumulous cloud and shown to have very good agreement and improved consistency between ATSR-2 and AATSR instruments, the Correlation with MAC-LWP increase from . 4 to over . 8 for these cloud regions. The flux products are compared with NASA Clouds and the Earth’s Radiant Energy System (CERES) data, showing good agreement within the uncertainty. The new dataset is well suited to a wide range of climate applications, such as comparison with climate models, investigation of trends in cloud properties, understanding aerosol-cloud interactions, and providing contextual information for collocated ATSR-2/AATSR surface temperature and aerosol products. For the Cloud_cci ATSR-2/AATSRv3 dataset a new digital identifier has been issued: https://doi.org/10.5676/DWD/ESA_Cloud_cci/ATSR2-AATSR/V003 Poulsen et al. (2019).
Monitoring of compliance with fuel sulfur content regulations through UAV measurements of ship emissions

Air pollution from ship exhaust gas can be reduced by the establishment of Emission Control Areas (ECAs). Efficient supervision of ship emissions is currently a major concern of maritime authorities. In this study, an Unmanned Aerial Vehicle (UAV)-based measurement system for exhaust gas from ships was designed and developed. Sensors were mounted on the UAV to measure the concentrations of SO2 and CO2 in order to calculate the fuel sulfur content (FSC) of 10 ships. The Waigaoqiao port in the Yangtze River Delta, an ECA in China, was selected for monitoring compliance with FSC regulations. Unlike in situ or airborne measurements, the proposed measurement system could be used to determine the smoke plume at about 5 m from the funnel mouth of ships, thus providing a means for estimating the FSC of ships. In order to verify the accuracy of these measurements, fuel samples were collected at the same time and sent to the laboratory for chemical examination, and these two types of measurements were compared. After 23 comparative experiments, the results 15 showed that, in general, the deviation of the estimated value for FSC was less than 0.03% (m/m) at an FSC level ranging from 0.035% (m/m) to 0.24% (m/m). Hence, UAV measurements can be used for monitoring of ECAs for compliance with FSC regulations.
