Published: October 2019

According to the Organization for Economic Cooperation and Development (OECD), the mean proficiency in literacy among adults in the US and Canada is at Level 2. Adults at this level cannot process dense texts, eliminate irrelevant information, perform multi-step operations, or evaluate the reliability of a source. The Reading Tutor is a website that was created to help low-literacy adults improve their English. It will be free to use the website that is personalized to the literacy level of every user. Creating a website allows people to increase their literacy levels without facing the stigma that comes with attending a class in person. Adults are inclined to improve their English because it often affects their career potential, socio-economic status, and health. The Reading Tutor has two major components: the passages and the scenarios. Passages are stories that the user can read and answer questions about. Scenarios are plots with questions that the user must answer to move on. In recent work, the information for each scenario was organized into spreadsheets to simplify the process of entering data into the code.

 The system architecture consists of HTML, CSS, Javascript, MySQL, Python, and Django. The newest development in this project was the improvement of the user intake experience. Before starting the passages and scenarios, the website collects information from each adult. The user "interests" pages are the latest additions to the site and these pages ask about the user’s hobbies. That data will then be used to incorporate their interests into later questions. It was important to add this feature to the website because relevance is a motivator for the user demographic. The next steps for the website are to log the user’s interests into the database. Future enhancements also include the creation of more scenarios to accommodate to the different user interests.
Optimal Zwitterionic Surfactant Slug for an Improved Oil Recovery in Oil Wet Carbonate Rocks - Silurian Dolomite
Authors: Esanullah Yosamin , Trivedi Japan , Nwani Benedicta , Barth Madison
Published: October 2019

The increase in energy demand has led to extensive research and development on economically, environmentally and technically feasible ways of improving the ever-growing energy demand. A common derivative of energy is from hydrocarbons, specifically oil. The process of oil recovery can be divided into primary, secondary, and tertiary recovery (also known as enhanced oil recovery). Once the internal pressure of a reservoir has depleted enough during primary and secondary recovery, more advanced techniques in enhanced oil recovery mechanisms are used to recover 50-80% of oil in the reservoir. Tertiary recovery includes the use of surfactants to reduce interfacial tension (IFT) or alter wettability. In this work, a zwitter ionic surfactant at two different concentrations is evaluated for its ability to reduce the interfacial tension between oil and water, as well as altering wettability in silurian dolomite. To achieve this, fluid-fluid analysis was done by a compatibility test, phase behavior test and interfacial tension measurements. Rock-fluid analysis was also completed by means of floatation test, carried out with carbonate rock particles to analyze the surfactant’s ability to alter wettability. Solution pH measurements were taken to validate the qualitative floatation test results. Results show that the surfactant, chembetaine C surfactant, is compatible with all ranges of salinities investigated, though was not able to produce a winsor type III micro-emulsion. The results of the interfacial tension measurements are in line with the phase behavior test, as none of the measurements were at ultra-low values. Surfactant retention is likely to occur with the analyzed zwitterionic surfactant based on the fluid-fluid analysis. Qualitative results from the floatation test show that the wettability of the carbonate rock particles cannot be significantly altered to more water-wet conditions. The pH of the solution remains at alkaline values, which can be beneficial in enhanced oil recovery in producing soap in situ, also known as saponification. Overall, tests conclude that this zwitterionic surfactant at 1% concentration would be most effective at 10,000 ppm salinity brine, though overall is not suitable for chemically enhanced oil recovery.
Manual versus automatic identification of black-capped chickadee (Poecile atricapillus) vocalizations
Authors: Ingolfsson Vala , Montenegro Carolina , Service William D. , Sturdy Christopher B.
Published: October 2019

One time-consuming aspect of bioacoustic research is identifying vocalizations from long audio recordings. SongScope (version 4.1.5. Wildlife Acoustics, Inc.) is a computer program capable of developing acoustic recognizers that can identify wildlife vocalizations. The goal of the current study was to compare the effectiveness of manual identification of black-capped chickadee vocalizations to identification by SongScope recognizers. A recognizer was developed for each main chickadee vocalization by providing previously annotated audio of chickadees. Six chickadees (three male, three female) were recorded in one-hour intervals with and without anthropogenic (i.e., man-made) noise to provide a variety of samples to test the recognizer. These recordings were analyzed via the recognizer and two human coders, with an additional third coder reviewing a random subset of recordings for reliability. Strong agreement was found between the human coders, κ = 0.76, p < 0.00. Agreement between human coders and the recognizer was moderate for fee songs, κ = 0.46, p < 0.00, and strong for fee-bee songs, κ = 0.77, p < 0.00, as well as for chick-a-dee calls, κ = 0.82, p < 0.00. Results showed that male chickadees produced more tseet calls in silence and females produced more gargle calls during noise. No differences were found in vocalizations based on time of day. Our observations also suggest that the chick-a-dee recognizer was capable of identifying gargle and tseet calls along with the intended chick-a-dee calls. Overall, SongScope was effective at identifying fee-bee songs and chick-a-dee calls, but not as effective for identifying fee songs. These recognizers can allow for faster acoustic analyses (by approximately four times) and be continuously improved for greater accuracy.
Changes in the Mechanical Response of Dental Stone to Submersion in Saline
Authors: Cai Joanne , Houg Kathryn , Romanyk Dan
Published: October 2019

Previously, dental stone has been utilized in mechanical testing of the periodontal ligament, which connects the tooth to the alveolar bone. This was achieved by casting swine mandibles in dental stone for displacement controlled testing. The stone was used as a riding base to hold the mandible in place. However, this was done in dry, ex vivo conditions, failing to simulate the natural presence of vascular fluid in the periodontal ligament. While this can be simulated with submersion in saline, the mechanical response of dental stone to saline is currently unknown, and thus cannot yet be used to secure the mandible in saline. To identify differences in the strength of dental stone after submersion in saline, Coecal Type III Dental Stone samples were cast in a 3D printed mold, then submerged in 0.9% NaCl solution for varying time periods: 0 hours, 0.5 hours, 1 hour, 4 hours, and 24 hours. Samples were then removed from the solutions, patted dry, and placed in an Instron ElectroPuls E3000 for compression tests. The Instron preloaded samples to 3 N, displaced them to 0.1 mm at 0.025 mm/s, held them for 10 s, then offloaded at 0.025 mm/s. This cycle was repeated five times per test, with each sample undergoing two tests. Results showed that the last three cycles of each test were most consistent, and were the only ones considered in further analysis of results. The average peak force and average force during the 10 s hold of each test were compared across submersion times, and, considering standard deviation, showed no consistent differences. A linear regression was completed to determine statistical differences between the force values. The p-values of the average peak force and average force were 0.624 and 0.892 respectively, approaching the required value of 1, and therefore failed to reject the null hypothesis, representing no significant difference in the average force across submersion times. As a result, it can be assumed that submersion in saline has no effect on the strength of dental stone. These results can be applied to further research on the periodontal ligament, involving submersion of the swine mandible in saline solutions.
Characterization of Lignin

Published: October 2019

Lignin is a complex organic compound crucial to the structural tissues of vascular plants, such as trees. The cyclic structure and aromaticity of lignin give it significant potential to be used as a renewable and safe replacement for toxic aromatic compounds in chemical and industrial processes. The purpose of this experiment was to characterize lignin, specifically the particle diameter and zeta potential, using both the Zetasizer Nano ZSP and the ImageJ image processing software, and to compare the accuracy of both measurement methods. Due to the natural fluorescence of lignin, a fluorescence microscope is used to capture images of lignin particles. By having a known distance and the scale of measurement, with ImageJ it is possible to calculate distances, such as the diameters of particles in images. The Zetasizer Nano ZSP is a device capable of measuring both particle diameter and zeta potential, which is the electrical charge existing on particles suspended in a medium. Small amounts of lignin, in powder form, are placed into scintillation vials with different amounts of distilled water to create 3 different concentrations of sample to measure using the Zetasizer. Between 10-15mL of sample are placed into specialized measurement cells and put into the Zetasizer. Multiple measurements are conducted and averaged to achieve accurate results. The measured zeta potential value is indicative of the stability of the lignin. If the value of zeta potential is higher than 30mV, negative or positive, it has a high stability and low reactivity. The average values of zeta potential measured by the Zetasizer ranged from -27mV to -21mV. The particle diameter is important in characterization, as the smaller and more distributed the particles are, there is a larger surface area for reactions to occur. Average particle diameter measured by the Zetasizer ranged from 926-976µm. The results from the Zetasizer Nano ZSP are more accurate than those from the ImageJ software, as ImageJ allows for a substantial amount of human error to impact the results. The outcomes help direct future experiments using lignin and beneficial to future research concerning lignin and its potential.
Design of a Braided Composite Badminton Racket on Solidworks
Authors: Neufeld Mackenzie , Ead Ahmed Samir , Lepp Eric
Published: October 2019

Current badminton rackets are typically made out of steel, aluminium, or carbon fibre. Although these materials perform acceptably, there are some downsides to their properties. However, these non-ideal characteristics of badminton rackets may be overcome with the usage of different manufacturing materials, specifically braided composites. An example of a braided material is KevlarⓇ. Kevlar is a heat resistant and high strength synthetic fibre that can be manufactured into braids using a maypole braiding system. These Kevlar braids can then be manipulated to a preferred shape for the curing process. In order to come up with a feasible design to base the prototype, a 3D modelling software (SolidWorksTM) is used. This ensures geometrical viability and possible to manufacture of the prototype. Modeling a badminton racket on Solidworks required the modelling of a racket head, and handle. The head was created using 2 ellipses, one of which acted as a skeleton, or mould for the Kevlar braid, and the other was a hollow ellipse which encompassed the mold and acted as the Kevlar braid. The solid ellipse was created in two halves, each having either an extrusion or a hole in the ends. This allowed them to easily attach to form a full ellipse. Once modeled, the solid ellipse was 3D printed to act as the curing mandrel, an internal skeleton for the Kevlar braids. In order to attach the head to the handle, a three-part connector piece was created and 3D printed. The rod of the racket was not created with an internal skeleton because the flexibility would falter. Instead, the Kevlar braids were slid off the material after curing and attached to the racket heads connector piece. In order to have a balanced weight ratio throughout the racket, the grip was created with an internal 3D printed skeleton. This structure allowed for a feasible, flexible, and strong Kevlar based product.
That which fits the mold: a braided composite wing
Authors: Saghar Nabiha , Lepp Eric , Ead Ahmed , Carey Jason
Published: October 2019

In this design study, a model airplane wing, partially constructed from braided composite panels, was made for the purpose of demonstrating the applications of braided composites for aerospace components. Fibres of Kevlar® were braided together along a tubular surface, then subsequently cut and unrolled to form two planar sheets of interlaced yarns that could be laid down in a 3D printed mold to later be coated in resin. The mold consisted of four parts: two female parts to shape the composite wing panels and two male parts to compress the composite. When connected together they form a fused core. A fibre sheet was draped over each female part, and its extraneous edges were folded inward to form a second layer as reinforcement. Each sheet was then laid up with Ecopoxy® resin and allowed to cure while sandwiched between the female mold and its corresponding male component. Upon disassembly of the mold system, a braided composite wing panel had formed upon both halves of the 3D printed core. The external portion of each panel was found to be smooth with few irregularities that could potentially compromise their aerodynamic performance. The mold was constructed to facilitate the process of cold-curing rather than curing at an elevated temperature. For heated cure process, the use of metal would be recommended because it generally deforms negligibly through heating and cooling. A metal mold would also be used to ease the process of debonding from the composite materials. Care should be taken to ensure that fibre orientation is consistent. The results illustrate how a mold can be fabricated to facilitate the process of curing braided composites, and can serve to improve the quality of products that require a higher strength to weight ratio.
Piecing Together Prehistoric Life: Scanning and Articulating Gorgosaurus

Published: October 2019

The Skull bones of a Gorgosaurus Libratus was laser scanned in order to articulate the model into software and 3D print. The model had to be articulated due to some missing bone, making it unrealistic to put together. Using the scanned pieces we articulated the model making a skull of The Gorgosaurus Libratus. This detailed computer skull can be sent anywhere in the world, for anyone to study. These scans could also be used to find out how the Gorgosaurus Libratus bit down or determine the way these animals moved. Prior to laser scanning, a method known as Photogrammetry was used. This method involves taking photos of the model and processing the images on a computer, which slow down the process. Another way used to replicate bones was by making silicone molds. This could damage the bone which makes it a method used less often. Laser scanning is the fastest and safest method in order to scan a bone. After the bones were articulated on the computer they were sent to a 3D printer. Unfortunately, the printer beds could not hold the massive skull. Due to this, the bones were printed half size. In order to 3D print, the holes of the model had to be filled using another program. The holes were caused by the light of the laser scanner not being able to go into all the holes creating shadows that the laser scanner could not pick up. However, after the holes were filled some of the objects were still too big to fit on the printer bed. Therefore, some of the objects were cut in half to fit. The 3D printed models were then printed and assembled.
Chest compression effectiveness with vs without feedback
Authors: Yang BinGe , Douma Matthew , Picard Christopher
Published: October 2019

The objective of this experiment is to assess clinician perceived versus actual compression quality, and to evaluate the impact of using feedback from the Laerdal CPRMeter2 on compression quality.  In our setup, we have a total of eighty four participants (43 from the Royal Alex and 41 from the Misericordia hospital). We monitored CPR quality based on the guidelines by Heart and Stroke, which breaks down chest compression effectiveness into three areas- Release, Depth and Rate. Proper Guidelines: Compress the chest at least 5cm (2inches); Compress at a rate of 100 to 120 beats per minute; Allow the chest to recoil completely after each compression. Clinical Setup: A convenience sample of participants performed two minutes of uninterrupted chest compressions on a Laerdal Resusci Anne with a CPRmeter2 on top without feedback, followed by a two minute rest period to fill out a Q.I tracking form. They later repeated the two minutes of chest compressions with the display of the CPRmeter uncovered, with the feedback visible. The chest compression metrics from the trials were compared using a data tracking form. From the data collected, enough evidence shows that the CPRmeter2 is able to improve release, rate and overall CPR quality. After filling out the survey, all of the nurses agree that the device is very useful in giving feedback and should be used in future CPR classes. Furthermore, data collected from the Q.I tracking forms indicates that nurses and other health clinicians are inadequate in predicting their own CPR abilities. Often times, nurses would either overpredict or underpredict their scores on the CPR meter. From the data gathered, the CPRmeter2 is going to be used for training in future CPR classes. Just recently, the device has been incorporated into code calls in the emergency department at the Misericordia. A T-test was done on the findings from the experiment to test if the means of two sets of data are significantly different from each other. Based on our findings, the t-test values for rate, release, and overall quality are statistically significant, meaning that the null hypothesis is rejected.

Published: October 2019

Cultivation of the Elephant Grass cv Taiwan with tissue culture requires an acclimatization stage, therefore this study aims to find the best planting media and the effect of plant age and evaluation of production elephant grass cv taiwan mutant and nutrient content. Acclimatization was carried out in a greenhouse using sand, soil, and a combination of 50% sand with 50% soil, and the mutant type T2, T4 and K4. The acclimation process uses the Factorial RAL method with factor A type of mutant and factor B type of planting media and the parameters assessed are leaf length, number of leaves and plant mortality rate. Production evaluation uses the RAL method and the parameters observed to see elephant grass production are plant height, stem diameter, leaf width, number of tillers and amount of plant biomass production. Proximate analysis is used to show the nutritional value of plants that have been selected individually using scoring assessments. The results of the acclimatization study showed that the planting media that had the lowest mortality rate were sand and soil combination media (22%) followed by soil planting media (27%) and the planting media that had the highest mortality rate was sand media (30%). The results of the production evaluation stage showed that the highest average harvest weight was found in T4 mutants with an average weight of 1353 g clump-1harvest-1, followed by T2 mutants which had an average of 1198 g clump-1harvest-1 and the lowest harvest weight was found in K4 mutants with an average of 1002 g clump-1harvest-1. Based on the research results obtained the best planting media for the acclimation process of elephant grass cv Taiwan mutants is a combination of sand and soil media (1:1). The results of the evaluation stage of T4 mutant production are the best mutants based on morphological performance and production of plant biomass. Proximate analysis of selected plants shows that plants with mutant T2PT7 species have the best nutritional value, with nutritional content of PK 11.71 and SK 24.67.

ENHANCED PERFORMANCE OF DYE-SENSITIZED SOLAR CELLS USING MELINJO PEEL (GNETUM GNEMON) DYE AS SENSITIZER
Authors: Hardani Hardani , Angraini Lily Maysari
Published: October 2019

It has been successfully identified and characterized by dye Melinjo peel (Gnetum gnemon) as an active material for Dye Sensitized Solar Cells (DSSC). The sample is formed in the structure of a working pair of electrode sandwiches and opposing electrodes. The dye extraction process (Dye) of the melinjo was stirred for 1 hour and then left to stand for 24 hours but there were only differences in how to doping dye into TiO2.Dye-sensitized solar cell (DSSC) is one of the photochemical electrical cells consisting of a photoelectrode, dye, electrolyte, and counter electrode. The purpose of using dyes in the DSSC is to extend the absorption spectrum to visible light because visible light has about 96% energy from sunlight. This article presents some experimental data on the nature of absorbance and the conductivity of natural dyes extracted from the plant as an application in the DSSC. Absorbance test using Spectrophotometer UV Visible 1601 PC and electrical properties test using Elkahfi 100 / Meter I-V. DSSC fabrication has been done using dye extract of melinjo (Gnetum gnemon) with a variety of immersion technique of drops and soak. The results show that natural dyes from natural material extraction have an absorbance spectrum of 380-520 nm range and the greatest conductivity is owned by melinjo (Gnetum gnemon). From the results of the test using AM Simulator 1.5G (100 mW / cm2) diesel simulator, it was found that the volume of TiO2 precursors affected the performance of DSSC solar cells and the overall conversion efficiency was 0.03% for the melinjo (Gnetum gnemon) dye by drops technique and 0.009% for the melinjo (Gnetum gnemon) dye by soak technique.

In the world of music, music has several types of genre genres that can be grouped, there are music genre pop, rock, blues, slow, jazz, metal, dangdut and many more. And for each person must have a genre favorite that is different from one another, but to distinguish it does not need to play music files one by one especially if the number of music files is a lot. Therefore, computer software is needed to distinguish each of these genres in order to make it easier for users to distinguish and group the types of music according to their wishes automatically. By using the MFCC and KNN methods as a classification solution to classify several types of genre streams can be easily resolved. The results achieved from this study reached 52,4% with a K = 13 as the nearest neighboring point.

As part of a transnational degree programme, students in the UK and China were linked together to carry out group work. This was enabled by having two versions of our FHEQ Level 4 Sustainable Chemistry module; in person for UK students, and by distance learning for Chinese students. Groups were instructed to discuss issues relating to the UN Sustainable Development Goals in their respective countries and report back individually. Students who found the assignment interesting were more likely to indicate they would keep in touch, while those students who had fewer interactions or found the assessment guidelines unclear found the assignment less interesting and were less likely to wish to remain in touch. This kind of assignment is an example of what can be done with links to other institutions around the world.

Published: October 2019

This article is aiming to investigate the emerging impact of industry-4.0 on supply chain integration and responsiveness in the electronics industry in China.  Specifically, it is to investigate the moderating effect of industry-4.0 as a strategic factor on the causal relationship from operational integration to supply chain responsiveness. This study develops hypotheses based the on selected literature reviews in the relevant research areas, and tests the hypotheses in the empirical sample data set collected from 76 electronics firms by using hierarchical multiple regression method.  The results of this study shows that industry-4.0 as an emerging strategic factor has not only directly helped the level of market responsiveness of the firms, but also has significantly strengthens the already proven positive causal relationship from operational integration within the supply chain to the overall market responsiveness as part of supply chain performance.  To improve the supply chain responsiveness in the electronics industry, managers can now make more confident and informed decisions to channel their resources towards the initiatives of industry-4.0 by up-grading perhaps their current information systems and business processes, knowing full well the dual benefits offered by the Industry 4.0 initiatives. The study extends the concurrent literature by conceptualising the moderating effect of industry-4.0 on the causal relationship between supply chain integration and business responsiveness.
An Ontology-based Ranking Model in Search Engines
Authors: Hou Yu , Tao Lixin
Published: October 2019

As the tsunami of data has emerged, search engines have become the most powerful tool for obtaining scattered information on the internet. The traditional search engines return the organized results by using ranking algorithm such as term frequency, link analysis (PageRank algorithm and HITS algorithm) etc. However, these algorithms must combine the keyword frequency to determine the relevance between user’s query and the data in the computer system or internet. Moreover, we expect the search engines could understand users’ searching by content meanings rather than literal strings. Semantic Web is an intelligent network and it could understand human’s language more semantically and make the communication easier between human and computers. But, the current technology for the semantic search is hard to apply. Because some meta data should be annotated to each web pages, then the search engine will have the ability to understand the users intend. However, annotate every web page is very time-consuming and leads to inefficiency. So, this study designed an ontology-based approach to improve the current traditional keyword-based search and emulate the effects of semantic search. And let the search engine can understand users more semantically when it gets the knowledge.

To explore the optimum temperature, light intensityand water conditions for seed germination of Siphonostegia chinensis Benth.,seed germination experiment were carried out under different temperatures（5/15, 10/20, 15/25, 20/30℃）, different light intensity（14h light/10h darkness, complete darkness）and different concentrations（0％, 5％, 10％, 15％, 20％）of PEG-6000 solution. In terms of concentration, 5% PEG was regarded as the low level, 10% and 15% as the medium level, and 20% as the high level. The results showed that (1) Germination rate, germination potential, and germination index were increased with the rise of temperature. In addition, seed germination was significantly higher under the dark conditions than that with the 14h light/10h darkness. (2) No seed germination occurred when the temperature was below 10/20 ºC at 14h light/10h darkness. (3) Under 14h light/10h darkness, the germination rate, germination potential and germination index first increased and then decreased with the increase of PEG concentration. The low concentration was more beneficial to the seed germination. (4) Under the condition of complete darkness, the germination rate, germination potential and germination index decline with fluctuation with the increase of PEG concentration. Seed germination of Siphonostegia chinensis Benth. was inhibited in high concentration of PEG.

Published: October 2019

There are presented results of experimental investigations allowing the definition of factors (parameters) influencing the accuracy of basing and fastening a tool in a machine spindle.

The plant design developed allows modeling the work of elements and mechanisms of a spindle unit of a jig-boring machine (JBM) at the moment of tool changing.

The series of experiments carried out allowed drawing the following conclusions:

- the accuracy of a tool installation in a machine spindle depends upon its angular position in a spindle taper;

- angular errors of a tool cone element decrease a rigidity of a “spindle-tool” subsystem by 10…15%;

- elastic movements in the area of a contact increase by 2-2.5 times at the presence of ovality in the cross-section of a holder (at ovality 18mkm);

- the accuracy of tool location in a spindle increases with the increase of an axial tightening force (recommended tightening force – 3 ≤ Ptight. ≤ 5kN);

- the holder operation results in the rigidity decrease of a tool system by 10…15% (operation term – 5 years).

Published: October 2019

A hybrid electromagnetic hanger is presented for high-speed vacuum transport means where a main force of levitation is created at the expense of constant magnets and an electromagnet performs air gap control. There is developed a computer model in MATLAB/Simulink program complex which allows carrying out the dynamic mode simulation of a system work. The simulation of transport means acceleration up to 1000 km/h taking into account road irregularities is carried out.
Pharmacophore Optimization Of Berberine As HER2 Inhibitor
Authors: Fadhil Pratama Mohammad Rizki , Pratomo Guntur Satrio
Published: October 2019

Penelitian sebelumya menunjukkan bahwa berberin, alkaloid yang terdapat pada beberapa tumbuhan seperti akar kuning (Arcangelisia flava) menunjukkan potensi inhibisi terhadap Human epidermal receptor-2 (HER2). Modifikasi pharmacophore pada struktur kimia berberin diprediksi dapat meningkatkan afinitas derivat berberin terhadap HER2. Tujuan penelitian ini adalah menemukan pharmacophore utama pada berberin yang memiliki pengaruh paling penting terhadap afinitas berberin pada HER2.

Metode yang digunakan adalah molecular docking hasil modifikasi pharmacophore terhadap HER2.

Hasil docking menunjukkan atom O pada posisi nomor 23 memiliki pengaruh penting terhadap afinitas berberin pada HER2, dimana modifikasi atom O menurunkan afinitas berberin. Afinitas tertinggi ditunjukkan oleh derivat berberin-6 dengan energi bebas ikatan dan konstanta disosiasi secara berturut-turut sebesar -10,80 kcal/mol dan 12,17 nM. Berbeda dengan derivat berberin lainnya, derivat berberin-6 tidak berinteraksi dengan asam amino treonin pada posisi 862. Hal tersebut memberikan prediksi bahwa interaksi pada asam amino tersebut berpotensi menurunkan afinitas berberin terhadap sisi aktif HER2. Lebih jauh derivat berberin-6 dapat dikembangkan menjadi inhibitor HER2 dan berpotensi untuk dikembangkan pada terapi kanker payudara HER2-positif.
High School Course Access and Postsecondary STEM Enrollment and Attainment

Published: October 2019

We study the effects of access to high school math and science courses on postsecondary science, technology, engineering, and mathematics (STEM) enrollment and degree attainment using administrative data from Missouri. Our data include more than 140,000 students from 14 cohorts entering the 4-year public university system. The effects of high school course access are identified by exploiting plausibly exogenous variation in course offerings within high schools over time. We find that differential access to high school courses does not affect postsecondary STEM enrollment or degree attainment. Our null results are estimated precisely enough to rule out moderate impacts.
The Impact of English Learner Reclassification on High School Reading and Academic Progress
Authors: Johnson Angela
Published: October 2019

This study estimates the causal impact of 8th grade English learner (EL) reclassification on high school English language arts (ELA) standardized test scores, SAT (Scholastic Aptitude Test) reading, and on-track to graduate status. I apply a regression discontinuity design to rich administrative data from a large district in California. The estimated effects of eighth grade reclassification on 9th, 10th, and 11th grade ELA test scores were statistically insignificant, and I can rule out negative effects less than −0.17 SDs and positive effects larger than 0.09 SDs. The negative effect on SAT reading was fairly large, with a confidence interval of −0.27 SDs to 0.05 SDs. Estimates for on-track status in 10th and 11th grades were positive but imprecise.

Despite the importance of sex for the maintenance of satisfying romantic relationships, our understanding of a person’s sexual ideals—the traits and attributes a person desires in a sexual partner or experience—and what might buffer against lower satisfaction associated with unmet sexual ideals, is limited. Across four studies including cross-sectional, dyadic, longitudinal, and experimental methods (N = 1,532), we draw on the Ideal Standards Model and theories of communal motivation to examine whether unmet sexual ideals are associated with lower sexual satisfaction and relationship quality and test whether higher sexual communal strength—the motivation to meet a partner's sexual needs—buffered these effects. Across studies, when individuals perceived their partner to fall short in meeting their sexual ideals, they reported poorer sexual and relationship quality. People with partners low in sexual communal strength reported poorer sexual satisfaction and relationship quality when their sexual ideals were unmet, but these associations were attenuated among people with partners who were high in sexual communal strength. Perceived partner responsiveness—both in general (Study 2) and to a partner’s sexual needs specifically (Study 3)—was one reason why people with partners high in sexual communal strength were buffered against the lower sexual and relational quality associated with unmet ideals. Please note this manuscript has received provisional acceptance in the Journal of Personality and Social Psychology.

Tourist’s loyalty is an important factor that tourist destination managements have to pay attention to. Thisis especially true for ecotourism destinations which cannot accommodate high numbers of visitingtourists. Having only a few but loyal tourists is the main concern of ecotourism managements, includingthe Gunung Api Purba Nglanggeran (Nglanggeran Ancient Volcano) Ecotourism management. The purpose of this study was to examine how the loyalty of tourists can be created by the factors of the tourist attraction, safety, and amenities, with satisfaction as an intervening factor, on the model of Community Based Tourism development in Gunung Api Purba Nglanggeran Tourism Village. The analytical method used was a path analysis with Partial Least Square (PLS). The results showed that the tourist attraction is a dominant factor that gives a positive influence on the loyalty of tourists through intervention variable satisfaction. Other factors studied, namely safety and amenities, are not proven to affect the loyalty of tourists. This research recommends that loyalty of tourists can be achieved through efforts to improve thequality of tourist attraction.Keyword: tourist attraction, safety, amenities, satisfaction, loyalty, Indonesia.
