Seismic Wavefield Sampling: A Wave Number Approach to Acquisition Fundamentals

The use of reflection seismic for the exploration of hydrocarbons entered a new epoch with the introduction of the horizontals tacking method in the early 1950s (Mayne, 1962, Sheriff and Geldart, 1982). In his pioneering article Mayne explained the benefit of using shorter receiver patterns for the preservation of reflected signals while delegating some of the groundroll suppression to the stacking process. For a long time the 6-fold stack was the ultimate of the seismic method, due to limitations in acquisition and processing hardware. Not until the late 1970s did reductions in station spacing, combined with a large increase in the number of recorded channels, allow higher stacking multiplicities leading to further drastic improvements in the quality of the final seismic reflection sections. The introduction of multiple-coverage recording called for the use of multichannel processing. Stacking, the multichannel process introduced first, was soon followed by post stack multichannel processes such as velocity filtering (Fail and Grau, 1963; Embree et al., 1963) and migration. Prestack multichannel processes became more feasible and even mandatory when the increase in number of recorded channels led to larger multiplicities and the reduced pattern lengths resulted in lower signal- to-noise (S/N) ratios. Some multichannel processes developed in the 1970s and 1980s are: multiple elimination, surface consistent statics correction, surface consistent deconvolution, slant stacking, dip move out (DMO) correction, and prestack migration. Most, if not all, of these techniques perform best for high multiplicities and regular spatial sampling. Though a variety of sophisticated multichannel processing techniques were developed by the best scientists in the industry, not much attention has been paid to the basic theories required for an optimal definition of acquisition parameters. Progress in the field of data acquisition has been driven by technology, experimentation and intuition, rather than by sound theories. A breakthrough in the formulation of seismic data acquisition techniques came with Nigel Anstey’s papers on the stack-array approach (1986a and b). Anstey’s recommendations, which were based on experience and intuition, need to be modified and extended on the basis of a more theoretical approach to the three-dimensional aspects of multiple coverage data. This theoretical background is provided here and the consequences for seismic data acquisition and seismic data processing are elaborated upon. The reader’s basic knowledge of the seismic method and of signal processing is assumed. Sheriff and Geldart (1982) is recommended as a more general introduction to seismic exploration Some aspects
EFL Students Attitudes Towards e-Learning And Effect of An Online Course on Students Success in English

In some state universities in Turkey, students are given English preparatory education for a year and in addition to formal education they receive in the classroom environment, they also have online education embedded with into their formal education as an extra opportunity provided ge nerally by online platforms. Within e-learning, students have online practice in relation to language areas such as grammar and vocabulary together with language skills except for speaking. Although learners have online course to support their formal class performances, the effect of online course on their overall success at preparatory classes is not clear. To have an insight into the possible effects of an online course on their success in English, 47 students were given a questionnaire to understand their attitudes towards online education, and their online scores were analyzed in comparison with their midterm and quiz scores. It was found that the students have partly positive attitudes towards online course; however, online course does not help students in terms of their overall success at preparatory class.
Educational leading as pedagogical love: the case for refugee education

ABSTRACT From a normative perspective, education serves a double purpose, that is, to prepare students to live well in a world worth living in. The practices of educational leadership are crucial elements in achieving this telos. In this article, we reimagine leading practices as pedagogical love, orchestrating conditions which enable refugee students’ academic achievements and overall school wellbeing. The article draws on a large, parallel case study which examined refugee education in Finland and Australia. The data used for this article consists of interviews with a leadership team in an Australian primary school. We argue that educational leading as pedagogical love needs to be reimagined as a co-constructed praxis between refugee children and educators, and that it can be enabled by a well-thought through combination of philosophy and practice. We suggest leadership practices as pedagogical love may disrupt the drive toward standardized curricula with its emphasis on performativity and testing. Exploring leading as pedagogical love allows us to show how love as a practice unfolds within the practice architectures of specific educational sites. As these practice architectures can be explored and theorized, they can also be transformed.
Not Just IQ: Patterning Predicts Preschoolers’ Math Knowledge Beyond Fluid Reasoning

ABSTRACT Preschoolers’ patterning skills are predictive of their concurrent and later math knowledge; however, it is unclear if patterning is only a proxy for general intelligence, or how it might support specific math skills. The current study examined the relation between 66 preschool children’s patterning skills and their general cognitive abilities, including fluid reasoning, working memory, and spatial skill. Further, the link between patterning and general math knowledge and specific math skills (i.e., numeracy and shape knowledge) was examined. Children’s patterning skills were significantly but only moderately linked to their performance on general cognitive ability measures (e.g., fluid reasoning). Further, beyond the effects of these general cognitive abilities, patterning significantly predicted both general math and numeracy knowledge, as well as verbal calculation and magnitude comparison. Thus, although patterning skills related to measures of general cognitive ability, patterning was a unique contributor to children’s general math and numeracy knowledge and specific math skills. Theories of math development and early math standards should thus be modified to emphasize the role of children’s patterning skills to their math development.
Knowledge and attitudes towards appropriate antibiotics usage among students-a survey

Antibiotics are used to treat bacterial infections. WHO estimates that more than half of all medicines are prescribed, dispensed or sold inappropriately, and that half of all patients fail to take them correctly. The overuse, underuse or misuse of medicines results in wastage of scarce resources and widespread health hazard. The objective of the study is to evaluate the knowledge and Attitude towards appropriate antibiotic use among students. A 15 item web based questionnaire was developed and employed to collect data from pharmacy students at Ezhuthachan College of pharmaceutical sciences. The survey will gather demographic information and collect data on knowledge, expectations and current antibiotic usage among students.A total of 55 students participated in the study, among the respondents about 60% of respondents believed that they could stop taking antibiotics if their symptoms of infection improved. over a half of the respondents (68%) believed that antibiotics are effective for most of the colds and around half of them (40%) stated that, they prefer to keep antibiotics at home for emergencies. About 58% would give their antibiotics to a family member if they caught an infection, 44% of respondents identified that, they have bought an antibiotic from community pharmacies without a prescription.The study shows that the pharmacy students has a number of misconceptions relating to appropriate antibiotic use, particularly relating to use of antibiotics for treatment of viral infections. As antibiotics are widely used in students, proper education should be given about rational use of antibiotics.
Association of Depression, Anxiety and Stress in Medical Students Studying in Modular, Semester and Annual Examination System

Background: When there are high demands besides less resources, a person experiences a feeling of fear that is known as “Stress”. Students of professional schools/colleges and universities are encounter more stress than the general population as they are in a transitory phase from adolescence to adulthood. It has been highlighted that medical education has greater association with stress. There are three examination systems that are been followed by medical colleges of Pakistan (modular, semester and annual systems). However, to the best of our knowledge, no data is available to show the association of stress with current examination systems in our country. Aims: The objectives of our study were to find out the association of stress with different examination systems and to identify the frequency of stress causing and coping factors adopted by 1st, 2nd and 3rd year medical students studying in colleges having different examination systems i.e. modular, semester and annual. Study Design: Comparative cross-sectional study. Place & Duration of Study: This study was conducted from December 2018 to April 2019 in three medical colleges of Sindh having above mentioned examination systems. Study Population: Medical students of 1st 2nd and 3rd year. Methodology: To assess depression, anxiety and stress among study population, DASS Scale was used. To identify the stress causing and coping factors in the students Likert scale based proforma with 19 factors were given to the selected participants Results: There was no significant association of examination system with depression, anxiety and stress, however various stress causing and coping factors were found significant in altering medical student`s life. Conclusion: According to our study, the frequency of stress in the medial students has no association with the examination systems (modular, semester and annual), currently followed by the medical colleges in Sindh, Pakistan.
Competing on Freemium: Digital Competition with Network Effects

“Freemium” product strategies—where a free basic version of a product is offered alongside a full “premium” paid version—are often used by companies to attempt to increase the size of their user base and benefit from network effects. However, there is limited empirical evidence of how this strategy impacts company performance. We investigate empirically how the strengthening of network effects on the Apple App Store influenced the revenues generated by market leaders and followers, contrasting firms that use paid only versus freemium strategies. We find that stronger network effects did not on their own lead to greater revenue for market leaders w.r. t. followers. However, in settings where freemium strategies were used, network effects greatly amplified the advantage of leaders over followers.
COLAB: Social Context and User Experience in Collaborative Multiplayer Games

Recent studies have shown that the social context in which people play digital multiplayer games has an effect on their experience. Whether co-players are in the same location (―co-located‖) or in different locations (―mediated‖) changes how they interact with the game and with one another. We set out to explore how these complex psychological dynamics played out in a collaborative multiplayer game, since most of the research to date has been focused on competitive gameplay scenarios. To this end, we designed a two-player puzzle-based gaming apparatus called COLAB, implementing specific features that have been proven to foster collaboration and preclude competition between players. The independent variable was player location; the dependent variable was game experience, as measured by the Social Presence in Gaming Questionnaire and the Game Experience Questionnaire, two comprehensive self-report instruments. We found a significant difference in the game experiences of players collaborating in the same location versus players collaborating in different locations. Specifically, co-located players of the collaborative game experienced significantly higher scores for negative experience than mediated players did, while mediated players experienced significantly higher levels of three key game-experience measures: positive affect, immersion, and flow.
Influence of Internet-Based Messages and Personal Motivations on Water-Use Decisions

Abstract This research investigates motives behind individual willingness to conserve water and if media messages can promote sustainable behaviors. Experiment 1 (n = 143) assessed water conservation motives after participants viewed a pro-conservation or neutral video. Disgust motivated refusing most sustainable water uses, especially for personal consumption. Experiment 2 (n = 591) examined the effectiveness of messages targeting underlying motives, and Experiment 3 (n = 152) examined the effect of pro-conservation media on willingness, intention, and behaviors regarding recycled water. Results suggest that pro-conservation messages can improve attitudes toward recycled water but not affect behaviors, thereby demonstrating limitations of correlational research.
Highly Sensitive and Stable NO2 Gas Sensors Based on SWNTs With Exceptional Recovery Time

Room temperature operable and highly sensitive NO2 gas sensors are fabricated based on (i) random and (ii) aligned networks of single-walled carbon nanotubes (SWNTs). The fabricated sensors are very sensitive, stable, and show shorter recovery time in the presence of UV light. Also, the variation of the response and recovery with network density is analyzed. The thin film resistor (TFR) of random network is fabricated by a reliable, cost-effective, and reproducible vacuum filtration method. The aligned network is fabricated using AC di-electrophoresis (DEP) technique. Electrodes spacing is optimized to avoid the chaining effect of aligned and bridged SWNTs between the gold electrode pair to enhance the stability and sensitivity of the sensor. Both the sensors based on random and aligned networks of SWNTs is tested with NO2 at room temperature. It is found that the sensor made of the aligned network shows ~3.5 times more sensitivity as compared to the random networks gas sensor but recovery time increases. It is also observed that sensors fabricated by TFR and aligned network techniques are stable and having less than 0.02 % and 0.15 % change in resistance with baseline, respectively. The TFR gas sensors fabricated using as prepared (AP) and purified and low functionality (P2) SWNTs show higher stability but less sensitive compared to the aligned network. The measured complete recovery time of sensors based on random and aligned SWNTs are 50 sec and 124 sec, respectively, for 0.5 ppm NO2. It is also observed that as the network density decreases response improves but the recovery time increases.

This research is a literature study that uses a qualitative descriptive approach. This study found that Islamic boarding schools have sufficient resources and capital to become the basis of the people's economic empowerment. With these resources and capital, Islamic boarding schools can carry out various activities oriented towards the economic empowerment of the surrounding community.
Examination of Test Anxiety in Samples of Australian and U.S. Higher Education Students

Invariance testing and correlational analyses were conducted on a new test anxiety questionnaire, the Test Anxiety Measure for College Students (TAM-C), with 1.050 Australian and U.S. higher education students. The samples were administered the TAM-C along with other questionnaires. Results from the aforementioned analyses supported a modified six-factor structure for Australian students, U.S. students, males, and females and strong invariance across countries and across genders. Latent mean factor analyses found differences across countries and across genders on the questionnaire and validity evidence for the TAM-C scores in the Australian and U.S. student samples were found. Implications of the findings for counselors and researchers who work with Australian and U.S. undergraduates are discussed.
Healthcare-Seeking Behaviour in Anyigba, North-Central, Nigeria

2 Abstract: This study of health seeking behaviour of household members in Anyigba, North Central Nigeria. Total 333 respondents were randomly selected and self-administered structured questionnaires were used to collect data on household health seeking behaviour. Descriptive and inferential methods were used to analyze the data. The mean age of respondents was 39.65±11.12 years, >3 quarter were married. The mean, median and mode delay time before seeking treatment were 9.89±46.03, 3.0 and 2.0 days, respectively. The major reason for the delay in seeking treatment as reported by 56.9% was the thought that they would get over the ailment without treatment and 25.4% of respondents delayed because of lack of money for treatment. Less than half (44.7%) of those who sought treatment patronized public health facility. The study showed that significantly higher proportion of the low income than high income people patronize drug sellers for treatment and higher proportion of the high income people than low income patronize private health facilities. Delay in receiving care for health problems can be costly and dangerous, it is necessary to increase awareness and to health educate people on this problem. Generally, more people in the study population patronize private health facilities, people's confidence in public health facilities need to be improved in Nigeria and should be made more accessible to people for improvement in the health status of Nigerians.
Extra-dyadic sexual fantasies involving idealized figures and regard for current partners

Abstract People in committed relationships may have idealized extra-dyadic sexual fantasies which involve someone other, and with greater desired attributes, than their current romantic partner. Using data from a national sample of Americans in committed relationships (N = 1108), we explored how the presence of two such fantasies – those involving strangers and/or former romantic partners – affected regard for one’s actual partner. Idealized extra-dyadic fantasies preserved partner regard in the low-sexual satisfaction condition but eroded partner regard among respondents reporting higher levels of sexual satisfaction. Noting this conditional relationship, we consider therapeutic uses of idealized extra-dyadic fantasies within couples therapy that avoid inadvertently eroding partner regard. This approach mainly consists of reorienting couples to each other and to the partner attributes that initially brought them together.
Concentrated disadvantage, racial disparities, and juvenile institutionalization within the context of attribution theory

ABSTRACT Prior literature has noted that disparities happen within the juvenile court process across a variety of contexts. However, research exploring this theme often neglects to use attribution theory to understand how external community-based attributions, particularly racialized interactions with real or perceived disadvantages within a community, as well as various internal attributions, and how these considerations shape placement decisions. Using quantitative juvenile court data from one southeastern state in the United States, supplemented with American Community Survey data, this study draws upon attribution theory to explore how internal and external attributions affect the placement decisions of serious and violent juveniles.
