Rolling a 7 with a pair of dice, breaking a mirror and getting cautioned about 7 years of bad luck, drinking 7-Up, flying in a Boeing 747, working at something 24/7, staying open 7 days a week: What is it about the number 7 that has made it such a common part of our vocabulary and daily lives? Whether discussing good or bad fortune, measuring time, or exploring a numerical framework within religions of the world, the number 7 has a special place in the world of numbers, numerals, and culture. How 7 took on such a key role in world cultures and mathematics is a rich and diverse story spanning all seven continents.

In this article, three different descriptions of curricula for scientific literacy (SL) are summarized, compared, and critically reviewed from the point of view of their suitability for all citizens. Science for All Americans, a publication of the American Association for the Advancement of Science, envisages giving every citizen a thorough exposure to the world of science, technology, and mathematics; the report Towards Scientific Literacy, published by the International Institute for Adult Literacy Methods, recommends a phenomenological approach to science designed to make science useful for people in their daily lives; and a similar curriculum, Minimum Science for Everybody, published by a voluntary organization in India, provides a detailed alternative conceptual framework for SL in which community traditions and knowledge systems are interfaced with science. The three reports are seen to differ from one another not only in respect of the contents of the curricula recommended, but also in their approaches, and the world views underlying these different approaches are brought out. It is suggested that SL curricula in both “developed” and “developing” countries be reviewed in the light of the ideas contained in all three reports in accordance with the needs and circumstances of the people. The article argues for the need to review the nature of science from the perspective of the common citizen.

AbstractIn 2019, the world celebrated the International Year of the Periodic Table of Chemical Elements (IYPT2019) and the IUPAC centenary. This happy coincidence offered a unique opportunity to reflect on the value and work that is carried out by IUPAC in a range of activities, including chemistry awareness, appreciation, and education. Although IUPAC curates the Periodic Table and oversees regular additions and changes, this icon of science belongs to the world. With this in mind, we wanted to create an opportunity for students and the general public to participate in this global celebration. The objective was to create an online global competition centered on the Periodic Table and IUPAC to raise awareness of the importance of chemistry in our daily lives, the richness of the chemical elements, and the key role of IUPAC in promoting chemistry worldwide. The Periodic Table Challenge was the result of this effort.

Background and Purpose The aim of this study was to clarify patients’ experiences of breathing during therapeutic processes in Norwegian psychomotor physical therapy (NPMP). Subjects and Methods A qualitative approach was used based on interviews with 9 women and 1 man aged between 41 and 65 years. The data were analyzed with the aid of grounded theory. Results Three categories were identified from the participants’ experiences: (1) “Breathing: An Incomprehensible and Disparate Phenomenon,” (2) “Breathing: Access to Meaning and Understanding,” and (3) “Breathing: Enhancing Feelings of Mastery.” Initially, breathing difficulties and bodily pains were described as physical reactions that seemed utterly incomprehensible to the participants. Communication, both verbal and nonverbal, between the patient and the physical therapist was described as vitally important, as was conscious attention to occurrences during the treatment sessions. The participants learned to recognize changes in their breathing patterns, and they became familiar with new bodily sensations. Consequently, they acquired new understanding of these sensations. The feeling and understanding of being an entity (ie, “body and soul”) emerged during therapy. The participants increased their understanding of the interaction between breathing and internal and external influences on their well-being. Their feelings of mastery over their daily lives were enhanced. The therapeutic dialogues gave them the chance to explore, reflect, and become empowered. Discussion and Conclusion In experiencing their own breathing, the participants were able to access and identify the muscular and emotional patterns that, linked to particular thoughts and beliefs, had become their characteristic styles of relating to themselves and the world.

How do we figure out the nature of the world from a mathematically formulated physical theory? What do we infer about the world when a physical theory can be mathematically formulated in different ways? Physics, Structure, and Reality addresses these questions, questions that get to the heart of the project of interpreting physics—of figuring out what physics is telling us about the world. North argues that there is a certain notion of structure, implicit in physics and mathematics, that we should pay careful attention to, and that doing so sheds light on these questions concerning what physics is telling us about the nature of reality. Along the way, lessons are drawn for related topics such as the use of coordinate systems in physics, the differences among various formulations of classical mechanics, the nature of spacetime structure, the equivalence of physical theories, and the importance of scientific explanation. Although the book does not explicitly defend scientific realism, instead taking this to be a background assumption, the account provides an indirect case for realism toward our best theories of physics.

In an age of social transformation characterized by globalization, wireless communication, and ease of travel and migration, more and more people around the world are marrying across national boundaries. This has occurred worldwide with the Gulf Cooperation Council (GCC) as no exception to this trend. As with the rest of the GCC, Qatar has witnessed remarkable social changes because of the discovery of petroleum resources that have affected the daily lives of people within Qatar in myriad ways. This includes marriage patterns, whereby cross-national marriages (marriages with non-Qataris) have shown a marked increase during the past few years, reaching 21% of total Qatari marriages in 2015 compared with only 16.5% in 1985.

Context: The transmission of COVID-19 was reported to have started at a Seafood Market in Wuhan, China predominantly through droplets from coughing and sneezing. Gatherings like schools, religious and worship centers as well as market places are usually densely populated and congested thereby facilitating the spread of the virus via droplets. This research aims to explore the transmission of COVID-19 in schools, religious gatherings and markets. Evidence Acquisition: Literature search of available evidences was conducted on biomedical databases such as PubMed and Google Scholar using keywords, and articles that met inclusion criteria were selected. Results: Results show that transmission of SARS-CoV-2 has been recorded in schools, religious centres and market places in different countries and regions. Transmission was found to be less prevalent among school children unlike in influenza outbreaks due to some notable factors highlighted in the articles. Numerous evidences stated cases of transmission of SARS-CoV-2 linked to intimacy and close contacts in religious gatherings. Transmission in market place marked the genesis of the pandemic at Huanan Seafood Wholesales Market, Wuhan although only limited evidences are available about transmission in other market places in the world. Conclusions: Although these gatherings are seen to be vital to our daily lives, they are risk settings for SARS-CoV-2 transmission. It is important for government to ensure strict compliance to the COVID-19 protocols in order mitigate the spread of the virus causing the current pandemic.

O discurso publicitário está presente no cotidiano das pessoas por meio de diversos tipos de mídia: anúncios na TV, impressos, outdoors ou nas redes sociais. Entre os recursos utilizados pela publicidade para convencer as pessoas sobre os produtos, serviços ou ideias que se deseja vender nos interessa estudar o uso da linguagem verbal, mais especificamente a maneira com que a publicidade constrói sentido por meio da linguagem. Assim, este artigo pretende analisar alguns enunciados de uma campanha publicitária realizada pela instituição financeira Citibank sob o olhar da teoria enunciativa desenvolvida por Oswald Ducrot. A campanha serve como  exemplo do jogo argumentativo que pode ser criado por meio da linguagem verbal, enredado em si mesmo, onde o locutor não fala sobre o mundo, mas fala para construir o mundo e explicitar a sua verdade por meio de argumentação linguística e não, necessariamente, retórica. Abstract: Advertising speech is present in people's daily lives through various types of media: TV ads, print ads, billboards, or social networks. Among the resources used by advertising to convince people about the products, services or ideas they want to sell we are interested in studying the use of verbal language, more specifically the way in which advertising builds meaning through language. Thus, this article intends to analyze some statements of an advertising campaign carried out by the financial institution Citibank under the view of the enunciative theory developed by Oswald Ducrot. The campaign is a great example of the game of argumentation that can be created through verbal language, entangled in itself, in which the speaker does not speak about the world, but speaks to build the world and to explain its truth through linguistic argumentation and not , necessarily, rhetoric.


The Autism Spectrum Disorder(ASD) are distinguished by persistent deficits in social communication and social interaction and restricted and repetitive patterns of behavior. Coronaviruses are an extremely common cause of colds and other upper respiratory infections. COVID-19, short for “coronavirus disease 2019”. The fast spread of the virus that causes COVID-19 has sparked alarm worldwide. The World Health Organization (WHO) has declared this rapidly spreading coronavirus outbreak a pandemic. Most of the countries around the world are adopting social distancing to slow the spread of coronavirus. There are several possible impacts of this pandemic on the daily lives of individuals with ASD, such as worsening of dysfunctional behaviors and regression of skills already acquired in different domains of development due to the social isolation. The objective of this article is to provide guidance to parents, health and education professionals that live or work with ASD individuals during the social isolation, on how to manage interventions that can be executed in the home environment, like remote training in language and social communication skills, behavioral strategies and sensory integration activities

The mobile applications industry has had significant growth in the last few years. Mobile phones are everywhere since we use them in every part of our daily lives for entertainment, communication and other various uses. Unfortunately, there was also a substantial increase the number of autism cases in kids around the world, which has prompted for a dire need of a therapy method that is cheap, reliable and accessible for everyone who needs it. Researchers have tried several methods, like robotics and virtual reality, to help in the therapy of autistic children. While their results were promising, these technologies are still out of reach of most users due to their high cost. Mobile phones, however, are much more accessible since everyone has one, and they have a wide array of useful gadgets that can be used in making the therapy sessions more engaging and fun such as cameras, accelerometers, speakers, microphones and others. This project aims to design and implement an interactive learning environment based on a mobile application for teaching kids with special needs.
