Product Matching Lessons and Recommendations from a Real World Application

Retailers rely heavily on product matching to better serve their customers, and to improve their modelling and forecasting. Product matching refers to the process of identifying similar or identical products across different data sources. This is a challenging problem as standardized unique identifiers are not used consistently across retailers, and product descriptions and characteristics vary across data collections. In this paper we present and discuss lessons learned from product matching in a real world application. We propose an evaluation framework where we investigate and compare the use of traditional machine learning methods and deep learning methods on public and proprietary datasets for product matching. Our findings show that traditional machine learning methods perform well on this task and a practitioner should investigate these methods first.
Seedless synthesis of gold nanorods with longitudinal surface plasmon resonance wavelength of 1200 nm

ABSTRACT Gold nanorods with the longitudinal plasmonic resonance peak position up to 1200 nm are prepared using an improved seedless synthetic technique. In this method, dopamine is employed as the weak reducer, whereas cetyltrimethylammonium bromide and sodium oleate are used as the binary surfactant mixture. Gold nanorods produced at various amounts of silver nitrate and hydrochloric acid were characterized by visible-near-infrared spectroscopy and scanning electron microscopy. Results show that the sizes, length-to-width aspect ratios, and the corresponding longitudinal surface plasmon resonance peaks of the synthesized gold nanorods can be tuned by altering the silver nitrate and hydrochloric acid amounts. The present method provides a new procedure for fabrication of gold nanorods with a broad range of plasmonic resonance peaks, which has a great potential for applications such as photothermal therapy and sensing.
PEER ASSESSMENT IN UNIVERSITY LEVEL: A PRELIMINARY STUDY ON THE RELIABILITY

This research aims to find out the reliability of peer assessment as a form of alternative assessment and as a part of student-centered learning process. The data was taken from one of the ‘Writing 3’ classes in English Language and Culture Department, which consist of fifteen students. The students were taught how they should conduct peer assessment, what rules they should follow, and how they should utilize the provided scoring rubric before they assessed their peers’ writing assignments. The writer, as the lecturer of the class, also conducted her own assessment using the same scoring rubric. The results of peer and teacher/lecturer assessment were compared and calculated using SPSS in order to find out whether the results of peer assessment have significant difference with the results of teacher/lecturer assessment. The result shows that there is no significant differences between the results of teacher assessment and peer assessment. This means that peer assessment could be implemented as a form of alternative assessment in writing classes. Penelitian ini bertujuan untuk mengetahui reliabilitas dari penilaian sejawat (peer assessment) sebagai suatu bentuk dari penilaian alternatif dalam kegiatan mengajar dan sebagai bagian dari proses pembelajaran yang berpusat pada pelajar (student-centered learning). Data untuk penelitian ini diambil dari salah satu kelas ‘Writing 3’ dari program studi Bahasa dan Budaya Inggris yang terdiri atas 15 orang. Para mahasiswa diajarkan bagaimana mereka seharusnya melakukan penilaian sejawat, peraturan apa yang harus mereka patuhi, dan bagaimana mereka menggunakan rubrik penilaian yang telah disediakan sebelum mereka akhirnya menerapkan kegiatan penilaian sejawat dalam menilai tugas menulis teman-teman mereka. Penulis, yang juga merupakan dosen dari kelas tersebut, juga melakukan penilaian dengan menggunakan rubrik yang sama. Hasil penilaian dari penulis dan dari para mahasiswa dibandingkan dan dikalkulasi menggunakan SPSS untuk mengetahui apakah nilai yang dihasilkan dari penilaian sejawat dan penilaian guru memiliki perbedaan yang signifikan. Hasil yang diperoleh menunjukkan bahwa tidak ada perbedaan yang signifikan antara kedua bentuk penilaian. Hal ini menunjukkan bahwa penilaian sejawat dapat digunakan sebagai bentuk penilaian alternatif dalam kelas menulis.
Exploring dominant child protection discourses: new possibilities for practice

This research study focuses on attachment theory as a dominant discourse in child protection and the experiences of child protection workers. The literature on attachment theory and its influence on Eurocentric/Western knowledge is reviewed. As well, the use of reflective practice in child protection practice is discussed. This study includes qualitative interviews with three child protection workers in Southern Ontario who discuss their practice. Four emerging themes were derived from the narratives of the participants: recognition of attachment theory as being the pinnacle of child protection practice, use of observation as a tool to assess attachment, use of reflective practice and lastly, the stigma of Children’s Aid Society and impacts on practice. The findings in this study suggest how practice is led by policies and standards of the child welfare system and is rarely challenged. The need for the child welfare system to validate parent/child beliefs, values and practices from various ethnicities is discussed.
An Improved GM-PHD Approach for Multi Extended Target Tracking with Square-root Cubature Information Kalman Filter

The conventional target tracking approaches are presented under the assumption of the point target. In multi extended target scenarios, the tracking performance of these approaches may be greatly decreased. The the Gaussian mixture (GM) implementation of the probability hypothesis density (PHD) (named as the ET-GM-PHD approach) has been presented for applying the GM-PHD approach into extended target tracking. However, it has been proposed under the linear models. In fact, most of targets are moving with nonlinear models. Thus, we, in this paper, present a square-root cubature information filter (SCIF) based ET-GM-PHD approach. To be more specific, we, first, employ the cubature points to predict the mean and the square-root factor of covariance. Then, the information forms of the mean and square-root of covariance has been used to update the mean and covariance of GM component. Meanwhile, we integrate the gating method into our method for saving computational complexity. Owing to the significant tracking performance of the SCIF method, our approach can estimate states and number of multi extended targets in nonlinear scenarios. In addition, we also propose an observation driven method to initiate the birth intensity. As for our method, the conditional probability has been adopted to describe the association between the target and its corresponding observations. With such a probability, the most possible partition, where the estimated targets belong to, can be approximated. Thus, the birth intensity can be estimated by removing the cells associated with the estimated targets. Since we use the estimated targets to initiate the birth intensity, our approach can initiate the birth intensity adaptively. The simulation results prove the effectiveness of our approach.
Decadal and Multidecadal Variability in ERSSTv5 Global SST During 1879-2018

: Decadal and multidecadal variability in the ERSSTv5 global SST dataset are studied in terms of implicit fast (noise) and slow (signal) processes that affect variability on decadal time scales. Using a new method that better estimates the fast, ornoise, component of decadal variability,estimates of themodesof variabilityin theslow componentare possible. The fast component of decadal variability has a leading fast mode, which explains 62% of the variance, and it is shown that this fast variability, or decadal climate noise, is well represented by any of the indices associated with intradecadal or interannual variability in the tropical Paciﬁc Ocean. Three slow modes are identiﬁed, representing 69% of the slow multidecadal variance, after removing the radiative forcing trend. These modes are shown to be related to variability in the Atlantic multidecadal oscillation (AMO) and SST multidecadal variability in the central western Paciﬁc and in the Indian Ocean gyre region,respectively.The ﬁrst and thirdslow modesrepresent two phases of a propagatingmode with a period of about 80 years. The second slow mode represents multidecadal variability of the western Paciﬁc warm pool, which is less robust than the other two and shown to be weakly related to the AMO with a lag of about 30 years; fast variability in this region is relatedto the leadingfast mode.Threeregionsof signiﬁcantslow variabilityare identiﬁedsouthof Australia,south of Africa, and near the Drake Passage in association with the Antarctic Circumpolar Current.

Recovery of valuable metals from lithium-ion batteries NMC cathode waste materials by hydrometallurgical methods

The paper focuses on the improved process of metal recovery from lithium-ion batteries (LIBs) lithium nickel manganese cobalt oxide (NMC) cathode waste materials by using hydrometallurgical methods. In the acid leaching step, the essential effects of acidity concentration, H2O2 concentration, leaching time, liquid-solid mass ratio, and reaction temperature with the leaching percentage were investigated in detail. The cathode material was leached with 2M H2SO4 and 10 vol. % H2O2 at 70 °C and 300 rpm using a liquid-solid mass ratio of 30 mL/g. In order to complete the recovery process, this paper designs the proper separation process to recover valuable metals. The leach liquor in the recovery process uses Cyanex 272 to first extract Co and Mn to the organic phase. Secondly, Co and Mn are separated by using D2EHPA, and a high purity of Co is obtained. Thirdly, Ni is selectively precipitated by using DMG, and Ni is completely formed as a solid complex. Finally, in the chemical precipitation process, the remaining Li in the leach liquor is recovered as Li2CO3 precipitated by saturated Na2CO3, and Co, Mn, and Ni are recovered as hydroxides by NaOH. This hydrometallurgical process may provide an effective separation and recovery of valuable metals from LIBs waste cathode materials.
Critical Thinking Ability Improvement: The Impact of STAD Learning Model in Mathematic Courses

According to some studies on school student, the application of the STAD method in some subject can improve critical thinking ability. However, according to other studies, STAD in some subject for school students cannot improve critical thinking ability. This study, hence, aims to discover the impact of the application of STAD in improving critical thinking ability, especially in mathematics course for university students. The experiment was carried out in a quasi-experimental design, especially the pretest-posttest non-equivalent group type. The findings of this study indicate that the application of STAD in mathematics learning can improve critical thinking ability. The advantages of using STAD can be seen from the increase in critical thinking ability, both abilities in the low, medium, and high categories. This study also confirms the findings of other studies that the application of cooperative and problem-based learning methods is effective in improving critical thinking ability. However, in contrast to other studies that reveal the benefits of STAD can be obtained after a long time of application (9 weeks - 8 months), this study shows that the benefits of STAD can be obtained in a relatively short time. This occurs because the treatment in the experimental class meets the criteria set by the experts, and uses three important structures proposed by experts, too. This research, therefore, has implications for the need to use problem-based cooperative learning methods.
Social skills levels for homeschooling students compared to public school students

In the United Sates, the use of education has been evolving in accordance with the needs of society. The primary role of education in the 20th century ranged from instructing the youth in various religious doctrines as well as preparing them to live independently. Schooling has also been critical in assimilating immigrants into the mainstream society as well as preparing workers for industrialization in the 20th century. Education was also essential in the 20th century as it acted as a tool of shaping and preparing the young for their futures in a rapidly changing world. Education in this error also worked as a tool for creating adults who can compete in a global economy as well as emotionally healthy adults who can engage in meaningful relationships. Key words: Education, homeschooling, online and distance education, social and behavioral, sociology.
Effects of Water Stress on the Phenolic Compounds of ‘Merlot’ Grapes in a Semi-Arid Mediterranean Climate

Of all the abiotic stress types to which plants grown in fields are exposed, the most influential is water stress. It is well accepted that adopting controlled deficit irrigation strategies during the growing season has beneficial effects on the chemical compositions of grapes and red wines. However, there is a discrepancy in the timing, intensity and duration of deficit. This study aimed to evaluate the changes in phenolic composition of ‘merlot’ cultivar grapes when subjected to different levels of water stress in a semi-arid Mediterranean climate. Four treatments with different water stress levels were applied within two phenological intervals (flowering-veraison, veraison-maturity) to 128 grapevines for two consecutive years. The water stress levels for Treatments 1, 2, 3 and 4 were: no-light, light-moderate, moderate-intense and intense for the flowering-veraison and veraison-maturity intervals, respectively. Water stress distinctly affected the phenolic compounds in skin and seeds. The concentrations of flavan-3-ols and total polyphenols were much higher in seeds than in skin, and in both fractions, tannins are the major compounds.

Challenges and Interventions of E‑learning for Underresourced Students amid Covid‑19 Lockdown: A Case of a Zambian Public University

This article reports the challenges of e‑learning faced by under-resourced students in a Zambian public university during the 2020 Covid‑19 lockdown. The article further examines the interventions made by the university to mitigate the challenges of e‑learning faced by under-resourced students. The article is based on empirical data derived from an online closed- and open-ended questionnaire completed by 73 under-resourced students, and an interview with two university staff. The quantitative and qualitative data collected were analysed using descriptive statistics and thematic analysis respectively. The article provides evidence that under-resourced students encountered various challenges related to e‑learning categorised under the following interlinked themes: technical, environmental, psychological, sociocultural, financial, and material. Lack of ICT facilities/devices (laptops, smartphones, tablets and desktops), internet, electricity, and support systems were the most critical barriers to e‑learning. Findings further showed that the sampled university made efforts to mitigate the challenges faced by students during e‑learning amid the 2020 Covid‑19 lockdown. However, there were no focused interventions to specifically address the actual challenges under-resourced students encountered. Regrettably, this suggests that the needs of under-resourced students were overlooked. Thus, the authors suggest strategies universities should put in place to uphold the participation of all students during e‑learning regardless of the circumstances.
Experimental determination and correlation of bosentan solubility in (PEG 200 + water) mixtures at T= (293.15–313.15) K

ABSTRACT The solubility of bosentan (BST) in the aqueous mixtures of polyethylene glycol 200 (PEG 200) at the temperature range, T = (293.15–313.15) K, has been studied using a shake-flask method. The experimental solubility data were correlated with Jouyban–Acree, Jouyban-Acree-van’t Hoff, modified Wilson and Yalkowsky models. Deviations of the calculated solubility from experimental one were determined by percent average relative deviations and relative deviations. In addition, to represent the thermodynamic behaviour of BST in PEG 200 solutions, the apparent thermodynamic functions, Gibbs energy, enthalpy and entropy of dissolution were obtained by using the van’t Hoff and Gibbs equations.
Linearly Polarized High-Purity Gaussian Beam Shaping and Coupling for 330 GHz/500 MHz DNP-NMR Application

Terahertz waves generated by vacuum electron devices have been successfully applied in dynamic nuclear polarization enhanced nuclear magnetic resonance (DNP-NMR) technology to significantly enhance the sensitivity of high-field NMR. To reduce the magnetic field interference, the high-power terahertz wave source and the NMR spectrometer need to be separated by a few meters apart. Corrugated horns and directional couplers are key components for shaping high linearly polarized terahertz Gaussian beam and accurately coupling electromagnetic power in the transmission system. In this paper, a corrugated TE11-HE11 mode converter and a three-port directional coupler realized by its inner cylindrical wire array are proposed for a 330 GHz/500 MHz DNP-NMR system. The output mode of the mode converter presents a characteristic of highly linear polarization, which is 98.8% at 330 GHz for subsequent low loss transmission. The designed three-port directional coupler can produce approximately −33 dB electromagnetic wave power on port 3 in the frequency range between 300–360 GHz stably, which can be used to measure the electromagnetic wave power of the transmission line in real-time. The designed mode converter and direction coupler can be installed and replaced easily in the corrugated waveguide transmission system.
Urodynamics in the evaluation of lower urinary tract symptoms in young adult men: A systematic review

Introduction: This review aims to systematically evaluate the available evidence on the different urodynamic diagnoses of lower urinary tract symptoms (LUTS) in young adult men aged 18–50 years and to summarize the various urodynamic parameters based on these diagnoses. Methods: This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement and the search was performed in PubMed, Embase, and Cochrane library from inception till September 2021. A total of 295 records were identified using a combination of keywords such as LUTS, urodynamics (UDS), and young males. The review was registered in PROSPERO (CRD42021214045). Results: All the ten studies, which were included in this analysis, categorised the patients into either of the four primary diagnoses after the UDS – primary bladder neck obstruction (PBNO), dysfunctional voiding, detrusor underactivity (DU), or detrusor overactivity. Five of these studies used the conventional UDS, and in the other five a video UDS was performed. The most common abnormality on the conventional UDS was DU with a pooled estimate of 0.24 (95% confidence interval [CI] - 0.104–0.463, I2-95.35, (τ2-1.07). The most common abnormality on the video UDS was PBNO with a pooled estimate of 0.49 (95% CI - 0.413–0.580, I2-66.59, 2-0.09). The point estimates of various UDS parameters were also recorded. Conclusion: A urodynamic diagnosis was possible in 79% and 98% of the young men who underwent a conventional UDS or a video UDS, respectively. However, the men subjected to the conventional UDS and the video UDS had significant differences in their primary urodynamic diagnostic label. These results will help to plan future trials for the evaluation and management of LUTS in young men.

The Influence of Religion on Life Satisfaction in Italy

Italy is the cradle of Catholicism and, despite the secularization process, religion continues to be part of its national culture. Although Italian sociologists have investigated the religious paradigm in Italy, there are aspects of such phenomenon still little explored. This paper examines the potential influence religion has on individuals’ life satisfaction. Data from the European Value Study survey provides evidence of a two-way interaction between religion and life satisfaction, with a substantial effect only in the case of public religious forms. This association seems to be moved by the mechanism of social support, and it differs across Italian regions. Results confirm the hypothesis that in areas of Italy more exposed to social isolation religion is associated whit life satisfaction because, in those areas, religion supplies peoples’ need to belong. Further confirmation of this analysis came from the fact that in grey zones of “religious conformism” the influence of religion on life satisfaction is marginal.
