To date, several studies have shown that the Earth's magnetic field suffers alterations at the local geographical location before an earthquake occur. Its study demonstrates that the Earth’s magnetic alterations at specific local geographical zone, is a local seismic precursor alerting a proximity of an earthquake with a margin of error of approximately 10%. The electromagnetic noise from background is very confusing, but that reason was necessary to identify these electromagnetic signal precursors by filtering a large amount of noise. To isolate the electromagnetic noise, was implemented a Magnetic North deflection detection in Smart Phones Magnetometers. Using it technology, was developed a mathematical algorithm that work in combination with the Smart Phones magnetometers. This research was based using in reference the study carried out by the Department of Physics of the Faculty of Physical Sciences and Mathematics (FCFM) of the University of Chile directed by Cordado, 2018[1], in the paper called “Latitudinal variation rate of geomagnetic cutoff rigidity in the active Chilean convergent margin”.

The BIO2010 report recommended that students in the life sciences receive a more rigorous education in mathematics and physical sciences. The University of Delaware approached this problem by (1) developing a bio-calculus section of a standard calculus course, (2) embedding quantitative activities into existing biology courses, and (3) creating a new interdisciplinary major, quantitative biology, designed for students interested in solving complex biological problems using advanced mathematical approaches. To develop the bio-calculus sections, the Department of Mathematical Sciences revised its three-semester calculus sequence to include differential equations in the first semester and, rather than using examples traditionally drawn from application domains that are most relevant to engineers, drew models and examples heavily from the life sciences. The curriculum of the B.S. degree in Quantitative Biology was designed to provide students with a solid foundation in biology, chemistry, and mathematics, with an emphasis on preparation for research careers in life sciences. Students in the program take core courses from biology, chemistry, and physics, though mathematics, as the cornerstone of all quantitative sciences, is given particular prominence. Seminars and a capstone course stress how the interplay of mathematics and biology can be used to explain complex biological systems. To initiate these academic changes required the identification of barriers and the implementation of solutions.

AbstractComputer programming is a key component of any physical science or engineering degree and is a skill sought by employers. Coding can be very appealing to these students as it is logical and another setting where they can solve problems. However, many students can often be reluctant to engage with the material as it might not interest them or they might not see how it applies to their wider study. Here, I present lessons I have learned and recommendations to increase participation in programming courses for students majoring in the physical sciences or engineering. The discussion and examples are taken from my second-year core undergraduate physics module, Introduction to Programming for Physicists, taught at The University of Manchester, UK. Teaching this course, I have developed successful solutions that can be applied to undergraduate STEM courses.

Over half of all students enrolling at a particular university in KwaZulu-Natal fail to complete a degree. This article is wanting to determine to what extent the marks they obtain for English and Mathematics at school impact on their probability of graduation at this university. In addressing this problem, other student specific factors associated with their gender, race and the type of school they have attended need also to be properly accounted for. To provide answers for this study, the performance of 24 392 students enrolling at the university over the period 2004 to 2012 was followed until they graduated or dropped out from their studies. A structural equation model was fitted because it allows one to separate a direct effect from that of an indirect effect. Gender, race and school background were found to be very significant with males, Black Africans and students coming from a less privileged school background having a smaller probability associated with eventually graduating from this university. Males tend to perform better than females in Mathematics, with females performing better males in English. More importantly, however, a single percentage point increase in one’s mark for English increases the probability associated with graduating from this university far more than would be the case if their Mathematics mark were to increase by a single percentage point. In the light of these mediated results, perhaps this university should be directing their efforts more towards improving the English (rather than mathematical) literacy of students entering the university.

Every institution needs repositories for storing, organizing, and presenting digital content, as well as maintaining digital resources for long-term digital access. The authors discussed India’s OpenDOAR status, a quality-assured listing of open-access repositories globally, with a particular emphasis on the Shodhganga repository. The focus of this paper is on universities in Northeast India that deposit Electronic Theses and Dissertations (ETDs) in the Shodhganga repository. This study depicts repositories in India since their inception. The Northeastern states are given special treatment by the Central Government and INFLIBNET in the form of Planners (Promotion of Library Automation and Networking in North Eastern Region). The study’s main goals are to disclose the knowledge outcome as well as the knowledge gap that exists in this geographical location. The study helps determine the number of universities in Northeast India that follow the “University Grants Commission (UGC) Minimum Standards & Procedure for Award of M.Phil. / Ph.D. Degree, Regulation, 2009,” which mandated that electronic version of Theses be uploaded to the Shodhganga repository for the benefit of scholars across the country.

We describe a unique Research Experience for Undergraduates and Research Experience for Veterinary students summer program at the National Institute for Mathematical and Biological Synthesis on the campus of the University of Tennessee, Knoxville. The program focused on interdisciplinary research at the interface of biology and mathematics. Participants were selected to work on projects with a biology mentor and a mathematics mentor in an environment that promoted collaboration outside of the students' respective disciplines. There were four research projects with teams of four participants and two faculty mentors. The participants consisted of a mixture of 10 undergraduates in biology- and mathematics-related disciplines, four veterinary students, and two high-school teachers. The activities included lectures on both the biological and mathematical backgrounds of the projects, tutorials for software, and sessions on ethics, graduate school, and possible career paths for individuals interested in biology and mathematics. The program was designed to give students the ability to actively participate in the scientific research process by working on a project, writing up their results in a final report, and presenting their work orally. We report on the results of our evaluation surveys of the participants.

Using stories in mathematics helps students situate mathematics within a context. This chapter presents an activity for the integration of stories and word problems into an algebra course designed for pre-service teachers. The pre-service teachers designed and created stories using technology (digital cameras and PowerPoint) to support algebraic explorations at the elementary and secondary levels based on the Common Core Standards. A balance of technology, language arts, and mathematics content is possible with these stories. The activity can be extended beyond the university classroom by guiding secondary students in creating their own algebraic stories in the classroom.

Past Half

During the past half century, ecology has emerged from its roots in biology to become a stand-alone discipline that interfaces organisms, the physical environment and human affairs. This is in line with the root meaning of the word ecology which is ‘the study of the household’ or the total environment in which we live. When I first came to the University of Georgia in 1940 as an instructor in the Department of Zoology, ecology was considered a rather unimportant sub-division of biology. At the end of World War II, we had a staff meeting to discuss ‘core curriculum’, or what courses every biology major should be required to take. My suggestion that ecology should be part of this core was rejected by all other members of the staff; they said ecology was just descriptive natural history with no basic principles. It was this ‘put down’, as it were, that started me thinking about a textbook that would emphasize basic principles, which eventually became the first edition of my Fundamentals of Ecology, published in 1953. In those early days ‘ecology’ was often defined as the ‘study of organisms in relation to environment’. The environment was considered a sort of inert stage in which the actors, that is the organisms, played the game of natural selection. Now we recognize that the ‘stage’ and the ‘actors’ interact with each other constantly so that not only do organisms relate to the physical environment, but they also change the environment. Thus, when the first green microbes, the cynobacteria, began putting oxygen into the atmosphere, the environment was greatly changed, making way for a whole new set of aerobic organisms. Also, when one goes from the study of structure to the study of function, then the physical sciences (including energetics, biogeochemical cycling and earth sciences in general) have to be included. And, of course, now more than ever, we have to consider humans and the social sciences as part of the environment. So we now have essentially a new discipline of ‘ecology’ that is a three-way interface.

The presence of technology on college campuses has increased rapidly in recent years. Students come to the classroom with a variety of technological devices including smart phones, tablets, or laptops and use them during academic activity. For this reason, there are many researchers who, in recent times, have been interested in the problems derived from digital distraction in higher education. In many cases, researchers have conducted studies and surveys to obtain first-hand information from the protagonists, that is, from university professors and students. Despite the efforts, there are many questions that still remain unanswered. The authors are aware of the enormous challenge that the use of technology poses in the university classrooms and want to delve into the causes and consequences of student digital distraction and the strategies that can be used by instructors to curb student digital distraction without deteriorating student-instructor rapport in the context of higher education.

The Neolithic long barrow whose excavation is described in this report is one of a pair known as Giants' Hills, situated in the parish of Skendleby, Lincolnshire (NGR: TF(53)429709; Lat. 53° 12′ 40″ N., Long. 0° 8′ 30″ E.). The general geographical location is an outlier of the chalk at the southern extremity of the Lincolnshire Wolds (fig. 1). The site lay at between 56 and 58m O.D. along the gentle south-facing slope of a small river valley (fig. 2). The maximum slope is 7 degrees. Orientation was approximately south-east/north-west with what can be considered the more important end of the barrow (the front) towards the south-east. The dimensions of the preserved mound were 65 × 13m (maximum) (originally 77 × 19m), and of the entire site from the original outer edges of the ditch, 89 × 29m (maximum).The other barrow of the pair, Giants' Hills 1, was excavated by C. W. Phillips (1936). To the south-east beyond a low chalk ridge and in a topographical position similar to that of the Giants' Hills barrows lies another pair of long barrows, the Deadmen's Graves (fig. 2). On a broader geographical scale, both pairs belong to a group of about fifteen long barrows situated on the Lincolnshire Wolds (fig. 1).Excavation took place under the direction of the authors at the instigation of the Department of the Environment (now the Historic Buildings and Monuments Commission for England) because of damage sustained by ploughing. As well as being a rescue operation, the work can be seen as an integral part of research into prehistoric chalkland environments and Neolithic burial practices. Thus, financial support was provided not only by the DoE, but also by University College Cardiff and the University of Leicester. There were three field seasons. In the first two, from 4–28 September 1975 and 27 March to 10 April 1976, the western end of the site (west of line AL, fig. 4) was excavated totally. The main excavation took place between 14 August and 25 September 1976.

I argue that if we distinguish between ontological realism and semantic realism, then we no longer have to choose between platonism and formalism. If we take category theory as the language of mathematics, then a linguistic analysis of the content and structure of what we say in and about mathematical theories allows us to justify the inclusion of mathematical concepts and theories as legitimate objects of philosophical study. Insofar as this analysis relies on a distinction between ontological and semantic realism, it relies also on an implicit distinction between mathematics as a descriptive science and mathematics as a descriptive discourse. It is this latter distinction which gives rise to the tension between the mathematician qua philosopher. In conclusion, I argue that the tensions between formalism and platonism, indeed between mathematician and philosopher, arise because of an assumption that there is an analogy between mathematical talk and talk in the physical sciences.
