Although the old problem of rotating liquid is described and solved in many textbooks and articles, the story still remains interesting. Intuitive understanding of the equipotential spatial surfaces is very difficult. This article is an attempt to present Newton's rotating tank in the light of the law of conservation of energy.

The so-called leaking STEM pipeline (dropout in STEM education) has been the subject of many studies. The large interest of scholars in plausible causes of this leakage has resulted in a number of meta-reviews describing factors at system, school and student level related to interest and persistence in STEM education. The STEM pipeline discussion…

The study examines the teachers' sense of overload and breaching the boundaries protecting their personal time during the COVID-19 crisis. The article explains the work-life conflict that teachers from all educational settings have encountered and the blurring of boundaries experienced as a result of ICT leakage into their personal space. Using a…

Mobile device security has become increasingly important in mobile computing. Since the mobile devices and applications are growing rapidly, the security threats are intensified due to mobile app flaws and lack of security consideration in early stages of software development. The unsecure software development process creates a serious weak path…

The Response Time-Based Concealed Information Test (RT-CIT) can reveal when a person recognizes a relevant ("probe") item among other, irrelevant items, based on comparatively slow responses to the probe item. For example, if a person is concealing his or her true identity, one can use the suspected identity details as probes, and other,…

Skills in science, technology, engineering and mathematics (STEM) are promoted by the Australian government as pivotal for Australia's economic prosperity. Research on equity groups suggests that group membership is associated with several factors linked to 'leakage' from the STEM pipeline of school, university and transition to work. In this…

More women are now entering male-dominated fields, yet, science, technology, engineering, and mathematics (STEM) remain dominated by men. We examined the association between boys' and girls' STEM choices after secondary education and friends' gender norms, and whether pressure to conform to traditional gender norms differs depending on the gender…

This longitudinal study of 17,455 students, the majority from underrepresented groups, investigated leaks in the vertical transfer pipeline from associate's-degree program entry to bachelor's-degree receipt. Investigated were both the size of the leaks and some associated variables. Pipeline progress examinations included quantification of early…

Studies of education and careers in science, technology, engineering, and math (STEM) commonly use a pipeline metaphor to conceptualize forward movement and persistence. However, the "STEM pipeline" carries implicit assumptions regarding length (i.e. that it "starts" and "stops" at specific stages in one's education…

Exam malpractice can be found in every nation in the globe. The practice of providing quality examinations in Ethiopian schools has ran into difficulties. The various forms of national examination malpractices, as well as preventative methods, were investigated in this study.A5-point rating scale labelled 'Forms of Examination Malpractices…

A fluorescence demonstration is described that incorporates several fundamental aspects of an introductory biochemistry course. A variation of a known leakage assay is utilized to prepare vesicles containing a quenched fluorophore. The vesicles are exposed to several osmotic environments ranging from isotonic to hypotonic. The degree of vesicle…

This article investigates what kind of multilingual operations are carried out as migrant and transnational creative writers deploy in their fictions in Italian (often an acquired language) the languages which they hold in their personal repertoires. Exploring first the linguistic, political and cultural implications of what Algerian author, Amara…

With the deep application of artificial intelligence and big data in education, adaptive learning has become a new research hotspot in online education. Based on the systematic review of the connotation and research progress of adaptive learning, a new definition of adaptive learning is given. By literature analysis, this paper points out the…

In standardized educational testing, test items are reused in multiple test administrations. To ensure the validity of test scores, the psychometric properties of items should remain unchanged over time. In this article, we consider the sequential monitoring of test items, in particular, the detection of abrupt changes to their psychometric…

It is shown that a particular class of pauses taken in both read and composed speech obey allometric laws such that mean pause length predicts body size. The pauses in this class have durations that roughly span 250 ms to 1,000 ms and are taken to mark grammatical and prosodic boundaries. A theory of pause allometry is developed based on the…
