Autonomy, Social Inequality, and Support in Chinese Urban and Rural Adolescents’ Reasoning About the Chinese College Entrance Examination (Gaokao)

The Gaokao, a mandatory postsecondary entrance examination for all Chinese students, is often associated with psychological stress among Chinese students in their final year of high school. This project was conducted in summer 2017 in urban Beijing and rural Xi’an, China. The purpose is to explore the perspectives of urban and rural secondary school graduates after they have completed the examination, using in-depth clinical interviews. The study draws on Self-Determination Theory and research on moral reasoning to examine several themes surrounding Chinese adolescents’ perceptions of the Gaokao, including general perceptions of the purpose of education, intrinsic and extrinsic motivation, sources of support and pressure during study for the Gaokao, and issues of fairness and social inequality. The major findings are that students from all backgrounds reported psychological conflict regarding their general views of the aims of education and the extrinsic pressure deriving from the high-stakes Gaokao examination. Inequality was seen as further exacerbated by family background, resources, and quality of teaching. Urban parents tended to provide more support, both academic and interpersonal. Rural students rated their mental health as significantly lower than urban students during their senior year of high school.

Push and Pull Motivations on Halal Tourism

The purpose of this study was to examine empirically the causal relationships among push and pull travel motivations, destination image, and tourists' travel satisfaction on halal tourism. The research conceptual framework and hypotheses were constructed, based on previous theoretical and empirical studies. A questionnaire survey was conducted with 200 respondents to collect the primary data. Multiple regression and Path Analyses were conducted to test the research hypotheses. As a result, push and pull factors had directly positive influences on tourist's travel satisfaction. Besides, the results also showed that push and pull factors were slightly indirect effect tourist's travel satisfaction through the halal destination image. Consequently, local government and business organizations working in the tourism sector should pay attention to the essential roles of push and pull factors. To attract more potential visitors and improve their satisfaction, enhance their perceived on halal destination image by doing the facility improvement and marketing activities are the compulsory actions. Keywords: destination image, halal tourism, motivation, push, and pull, travel satisfaction.
Automated simulation-generated EO/IR image library for artificial intelligence applications

The emergence of machine learning into scientific fields has created opportunities for novel and powerful image processing techniques. Algorithms that can perform complex tasks without a “man-in-the-loop” or explicit instructions are invaluable artificial intelligence tools. These algorithms typically require a large set of training data on which to base statistical predictions. In the case of electro-optical infrared (EO/IR) remote sensing, algorithm designers often seek a substantial library of images comprising many weather conditions, times of day, sensor resolutions, etc. These images may be synthetic (predicted) or measured, but should encompass a large variety of targets imaged from a variety of vantage points against numerous backgrounds. Acquiring such a large set of measured imagery with sufficient variation can be difficult, requiring numerous field campaigns. Alternatively, accurate prediction of target signatures in cluttered outdoor scenes may be a viable option. In this work, sensor imagery is generated using CoTherm, a co-simulation tool which operates MuSES (an EO/IR simulation code) in an automated fashion to create a large library of synthetic images. The relevant MuSES inputs – which might include environmental factors, global location, date and time, vehicle engine state, human clothing and activity level, or sensor waveband – can be manipulated by a CoTherm workflow process. The output of this process is a large library of MuSES-generated EO/IR sensor radiance images suitable for algorithm development. If desired, synthetic target pixels can be inserted into measured background images for added realism.
Sustainable Method for the Synthesis of Alternative Bis(2-Ethylhexyl) Terephthalate Plasticizer in the Presence of Protic Ionic Liquids

Inexpensive Brønsted acidic ionic liquids based on trimethylamine and sulfuric acid are proposed as both solvents and catalysts in the synthesis of alternative plasticizer bis(2-ethylhexyl) terephthalate, which has a broad spectrum of applications in plasticization processes. The utilization of 50 mol % of Brønsted ionic liquid led to the full conversion of terephthalic acid after 8 h of reaction at 120 ◦C. Additionally, a 100% selectivity of bis(2-ethylhexyl) terephthalate was obtained. The advantage of the presented reaction system is based on the formation of a biphasic system during the reaction. The bottom phase consists of an ionic liquid and water, and the upper phase is created by the ester and unreacted alcohol. This phenomenon helps overcome the equilibrium of the reaction and drives it towards a high yield of product. The presented new approach is proposed as a safe, cost-effective, and alternative method to conventional processes with organometallic compounds that, in turn, leads to greener and a more economically viable technology.
Cup of coffee at the library? Factors influencing consumers’ acceptance of foodservice at the library / Hashim Fadzil Ariffin... [et al.]

Young consumers, especially students, are experiencing the coffeehouse culture or the chill-out factor. Considering these factors as a potential determinant for student to visit a place, library management should take these opportunities to introduce an eatery inside the library. The objective of this study is predominantly to assess the relationship between foodservice acceptance, menu offerings, service quality, environment and price among library users. Questionnaires that consist of foodservice acceptance, menu offerings, service quality, environment and price were distributed to 300 students from 3 public universities in Klang Valley. Findings show that the significant relationships between menu offerings, environment, price and foodservice acceptance are confirmed in Structural Equation Modelling (SEM). On the other hand, service quality indicates the insignificant relationship with foodservice acceptance. The results provide information that can be utilized in understanding, maintaining, and increasing the level of foodservice acceptance that leads to library patronage amongst students. Implications and suggestions for future research are also provided.
A 10-year single-center experience on Stenotrophomonas maltophilia resistotyping in Szeged, Hungary

Stenotrophomonas maltophilia is an aerobic, oxidase-negative and catalase-positive bacillus. S. maltophilia is a recognized opportunistic pathogen. Due to the advancements in invasive medical procedures, organ transplantation and chemotherapy of malignant illnesses, the relevance of this pathogen increased significantly. The therapy of S. maltophilia infections is challenging, as these bacteria show intrinsic resistance to multiple classes of antibiotics, the first-choice drug is sulfamethoxazole/trimethoprim. Our aim was to assess the epidemiology of S. maltophilia from various clinical samples and the characterization of resistance-levels and resistotyping of these samples over a long surveillance period. The study included S. maltophilia bacterial isolates from blood culture samples, respiratory samples and urine samples and the data for the samples, received between January 2008 until December 2017, a total of 817 S. maltophilia isolates were identified (respiratory samples n = 579, 70.9%, blood culture samples n = 175, 21.4% and urine samples n = 63, 7.7%). Levofloxacin and colistin-susceptibility rates were the highest (92.2%; n = 753), followed by tigecycline (90.5%, n = 739), the first-line agent sulfamethoxazole/trimethoprim (87.4%, n = 714), while phenotypic resistance rate was highest for amikacin (72.5% of isolates were resistant, n = 592). The clinical problem of sulfamethoxazole/trimethoprim-resistance is a complex issue, because there is no guideline available for the therapy of these infections.
LWD Acoustic Application for Cement Bond Evaluation: A Case Study in Brazil

Well integrity is very important for well operation in oil and gas industry. Advanced technologies and analyses have been developed to ensure well integrity. One of the most important analysis to be done is the evaluation of the cement bond which measures the presence and bonding of cement between casing and the formation in a particular depth or interval. This evaluation is critical for hydraulic isolation to withstand subsequent completion and production operation. Usually, Cement bond evaluation is done from wireline logging, with a tool that transmits acoustic waves and compute the acoustic energy propagating through the casing, the cement and the formation. The amplitude and the attenuation of the returned wave can be correlated with Bond Index (BI), due to the difference in acoustic impedance between casing and cement. Over years, different wireline technologies have been developed and matured for cement bond evaluation. Nowadays, it can be found scenarios where wireline operation is not feasible, such as in highly deviated wells or when a quick turnaround is needed. Acoustic technology in Logging While Drilling (LWD) has been developed to measure the compressional and shear slowness of the formation. These devices are able to transmit acoustic wave at different frequencies and receive them after propagation through a medium, applicable in cased hole condition. This paper presents a case study where the LWD Acoustic technology was successfully used to evaluate the cement bond in a high deviated well in Brazil and the results show the capabilities of the technology to generate a qualitative cement bond data quality. These results were successfully validated using sonic and ultrasonic wireline technologies. This comparison, between LWD acoustic and wireline results, is shown in this paper, including details of the methodology applied to the test, parameters considered and the data processing.
Factors and Paths of Transformation and Upgradation of Chemical Industry in Shandong, China

In the context of the Internet, there is a historical fusion between the new round of scientific and technological revolution and industrial transformation and the accelerated transformation of economic development methods. The task of the Shandong chemical industry’s transformation and upgradation is arduous and urgent. In this context, this article studies the influencing factors and development paths of the transformation and upgradation of the Shandong chemical industry. It provides theoretical guidance for high-quality and sustainable development of the Shandong chemical industry. First, this paper uses the fuzzy cognitive map tool to learn the historical laws of the transformation and upgradation of the Shandong chemical industry. It then determines the path of chemical industry transformation and upgradation, according to the interactions and weights between the learned indicators. By adjusting the influence coefficient between the indicators on each path, the degree of change in the influence of the indicator on the target value is analyzed. The critical path and the key indicators on the path according to the degree of impact are determined. Finally, the key path selected in this article is: return on investment (C8) → unit production value environmental consumption (C9) → number of R&D personnel (C4) → R&D expenditure internal expenditure (C6) → industrial output (C1) → energy consumption coefficient (C3). The key indicator on this path is R&D expenditure internal expenditure. According to the results, the development suggestion for the transformation and upgradation of the chemical industry in Shandong is to take the path of green development through technological innovation.
Pentaric Acids and Derivatives from Nitric Acid–Oxidized Pentoses

This report describes the preparation of the four stereoisomeric pentaric acids by nitric acid oxidation of d-xylose, d-arabinose, l-arabinose, and d-ribose, with xylaric, d-arabinaric, and l-arabinaric acids being made in a reactor under computer control. The pentaric acids were converted to their crystalline N,N′-dimethylpentaramides, derivatives that proved useful for isolation of the arabinaric acids from their respective oxidation mixtures. The N,N′-dimethylpentaramides were readily convertible to the corresponding pentaric acid disodium salts in aqueous sodium chloride. The 2,3,4-O-triacetyl-N,N′-dimethylpentaramides of xylaric, l-arabinaric, and ribaric acid were also prepared. Ribaric acid was isolated as crystalline 1,4(5,2)-ribarolactone and further characterized by x-ray crystallography.
Production of γ-Aminobutyric Acid By Cheese Starters During Cheese Ripening

Nine mixed-strain starters were examined for their abilities to produce γ-aminobutyric acid. Six commercial starters were found to produce γ-aminobutyric acid in a skim milk culture. The bacterium that produced γ-aminobutyric acid was isolated from the mixed-strain starters, identified as citrate-utilizing Lactococcus lactis ssp. lactis (formerly L. lactis ssp. lactis biovar diacetylactis) and designated as strain 01-7. A cell extract showed glutamate decarboxylase activity, for which the optimum pH was 4.7. In pH-controlled cultivation, γ-aminobutyric acid was generated at pH 5.0 but not above pH 5.5. Cheeses were prepared experimentally using strain 01-7 to determine the relationship between the pH values and the production of γ-aminobutyric acid during cheese ripening. γ-Aminobutyric acid increased linearly in the experimental cheeses as the pH of the cheese decreased. Based on these results, γ-aminobutyric acid was concluded to be produced by the cheese starters during ripening.
Accurate high-resolution single-crystal diffraction data from a Pilatus3 X CdTe detector.

Hybrid photon-counting detectors are widely established at third-generation synchrotron facilities and the specifications of the Pilatus3 X CdTe were quickly recognized as highly promising in charge-density investigations. This is mainly attributable to the detection efficiency in the high-energy X-ray regime, in combination with a dynamic range and noise level that should overcome the perpetual problem of detecting strong and weak data simultaneously. These benefits, however, come at the expense of a persistent problem for high diffracted beam flux, which is particularly problematic in single-crystal diffraction of materials with strong scattering power and sharp diffraction peaks. Here, an in-depth examination of data collected on an inorganic material, FeSb2, and an organic semiconductor, rubrene, revealed systematic differences in strong intensities for different incoming beam fluxes, and the implemented detector intensity corrections were found to be inadequate. Only significant beam attenuation for the collection of strong reflections was able to circumvent this systematic error. All data were collected on a bending-magnet beamline at a third-generation synchrotron radiation facility, so undulator and wiggler beamlines and fourth-generation synchrotrons will be even more prone to this error. On the other hand, the low background now allows for an accurate measurement of very weak intensities, and it is shown that it is possible to extract structure factors of exceptional quality using standard crystallographic software for data processing (SAINT-Plus, SADABS and SORTAV), although special attention has to be paid to the estimation of the background. This study resulted in electron-density models of substantially higher accuracy and precision compared with a previous investigation, thus for the first time fulfilling the promise of photon-counting detectors for very accurate structure factor measurements.
Evaluating the link between attendance and performance in higher education: the role of classroom engagement dimensions

Abstract Does attendance matter? This question has still not been answered conclusively. In general, studies find positive but mostly weak correlations between attendance and performance. However, due to technological changes in learning, attendance in higher education seems to lose its importance since students do not have to attend class to get access to course material. The question that arises is whether information on purely descriptive attendance is sufficient to prove the positive effects of attendance on performance. This study takes a closer look at the link between attendance and performance, examining classroom engagement dimensions as mediating factors. The results suggest that it does not matter if but rather how students attend class.
Photoreduction of O2 Primes and Replaces CO2 Assimilation

A mass spectrometer with a membrane inlet system was used to monitor directly gaseous components in a suspension of algae. Using labeled oxygen, we observed that during the first 20 seconds of illumination after a dark period, when no net O 2 evolution or CO 2 uptake was observed, O 2 evolution was normal but completely compensated by O 2 uptake. Similarly, when CO 2 uptake was totally or partially inhibited, O 2 evolution proceeded at a high (near maximal) rate. Under all conditions, O 2 uptake balanced that fraction of the O 2 evolution which could not be accounted for by CO 2 uptake. From these observations we concluded that O 2 and CO 2 are in direct competition for photosynthetically generated reducing power, with O 2 being the main electron acceptor during the induction process and under other conditions in which CO 2 reduction cannot keep pace with O 2 evolution. The high rate of the O 2 uptake reaction observed in the presence of iodoacetamide, KCN, or carbonyl cyanide p -trifluoromethyoxyphenylhydrazone, suggests that a special high capacity oxidase distinct from ribulose diphosphate oxygenase exists in whole cells. The rapid reduction of molecular O 2 after a period of darkness probably serves as a priming reaction for the photosynthetic apparatus. The high steady state rate of the O 2 cycle in the absence of CO 2 fixation suggests that the regulation of photosynthesis does not involve significant changes in the rate of photochemical electron transport.

Karaoke Instagram

In this study, I compare and contrast online and offline performances of karaoke and ask, what are the material phenomena associated with the two practices? How are they different and/or the same? What does this tell us about the connection between performance and technology, especially in relation to amateur singing and its mediatized forms? Following this mode of enquiry, I find that examples of online and offline karaoke provide useful insight into ways amateur performances are inevitably permeated by commerce. I also offer hope and guidance towards how future networks of amateur performances might escape this fate. I have begun a new study of karaoke in and around Columbia, Missouri (USA), with a special focus on local singing in rural communities. Alongside this I am examining how karaoke has grown into a pervasive online genre of amateur performance. I’m doing extensive research of performances of karaoke presented on social media sites like Instagram, Facebook, YouTube and TikTok. This ongoing study seeks to reveal connections between desire and materialism – drawing parallels between karaoke, online commerce and commercialism – as well as exploring the flattening and globalizing of local performance when presented on social media. In a brand new world where ‘anyone can do it’, businesses keep finding new ways to draw people in and capitalize on their desire for celebrity, even if they are only famous for a few minutes. While karaoke may begin as a kind of amateur local singing that provides consumers with an open media text, the possibility of agency in its interpretation becomes closed the instant it hits the global network. Once these performances are reactivated on social media, any ‘voids’ that karaoke opens up are almost immediately commodified and closed.

Evaluation of Academic Staff Job Satisfaction at Malaysian Universities in the Context of Herzberg’s Motivation-Hygiene Theory

Most academic staff don’t know what exactly makes them satisfy or dissatisfy at university and based on which effective factors they can improve and increase the level of their outcomes. Dissatisfaction occurred amongst academic staff when they don’t receive any basic motivational factors, versa job satisfaction happened when they obtained at least the fundamental facilities and considered via workplace (managers, leaders, and supervisors). There are numerous and effective factors that change attitudes and feelings of academic staff toward the job, likewise, change level of their outcomes; furthermore, recognizing these effective factors that rise level of job satisfaction among these group of staff; similarly, analyzing this factor as one of the important organizational factors in the context of Herzberg’s Motivation-Hygiene Theory determined as main objective of this literature review. Overall, in this research endeavors to finding brilliant points and motivational factors that influence job satisfaction and clarifies them in an educational situation such as the university.
