RESEARCH which goes to the core of the problem directly and with finesse can elicit admiration. The investigation reported in this issue by Dancis and colleagues will find a number of readers experiencing such appreciation. Hypervalinemia has been reported in only one infant in the world, but rarity is not the reason for its interest; this "experiment of nature," discovered as if by accident, has been a most informative disease. Working with as little as 2 ml of blood taken from the patient, Dancis and colleagues studied the metabolism of valine in the white cells in the sample. The simplicity of the "biopsy" and the elegance of the isotope methods are most exemplary.

Each religious sect has its own characteristics, whether fundamental, radical, or religious. One of them is Insan Al-Kamil Congregation, which is in Cijati, South Cikareo Village, Wado District, Sumedang Regency. This congregation is Sufism with the concept of self-purification as the subject of its teachings. So, the purpose of this study is to reveal how the origin of Insan Al-Kamil Congregation, the concept of its purification, and the procedures of achieving its purification. This research uses a descriptive qualitative method with a normative theological approach as the blade of analysis. In addition, the data generated is the result of observation, interviews, and document studies. From the collected data, Jamaah Insan Al-Kamil adheres to the core teachings of Islam and is the tenth regeneration of Islam Teachings, which refers to the Prophet Muhammad SAW. According to this congregation, self-perfection becomes an obligation that must be achieved by human beings in order to remember Allah when life is done. The process of self-purification is done when human beings still live in the world by knowing His God. Therefore, the peak of self-purification is called Insan Kamil.

The world has been surprised by the emergence of a COVID 19 pandemic, was born in China, and widespread to various countries in the world. In Indonesia, the government issued several policies to break the COVID 19 pandemic chain, which also triggered some pro-cons in the midst of society. One of the policies government takes is the closure of learning access directly at school and moving the learning process from physical class to a virtual classroom or known as online learning. In the economic sector also affects the parents’ financial ability to provide sufficient funds to support the implementation of distance learning applied by the government. The implications of the distance education policy are of course the quality of learning, including the subjects of Islamic religious education, which is essentially aimed at planting knowledge, skills, and religious consciousness to form the character of the students. Online education must certainly be precise, in order to provide equal education services to all students, prepare teachers to master the technology, and seek the core learning of Islamic religious education can still be done well.

Despite the dumbing-down of education in recent years, it would be unusual to find a ten-year-old who could not name the major continents on a map of the world. Yet how many adults have the faintest idea of the structures that exist within the Earth? Understandably, knowledge is limited by the fact that the Earth’s interior is less accessible than the surface of Pluto, mapped in 2016 by the NASA New Horizons spacecraft. Indeed, Pluto, 7.5 billion kilometres from Earth, was discovered six years earlier than the similar-sized inner core of our planet. Fortunately, modern seismic techniques enable us to image the mantle right down to the core, while laboratory experiments simulating the pressures and temperatures at great depth, combined with computer modelling of mantle convection, help identify its mineral and chemical composition. The results are providing the most rapid advances in our understanding of how this planet works since the great revolution of the 1960s.

Food chains interact with the vast, complex, and tangled webs of material flows —nitrogen, phosphorus, carbon, water, energy—circling the globe. Cities and households are where those material flows interact with the greatest intensity. At every point within these webs and chains, technologies enable them to function: from bullock-drawn ploughs, to mobile phones, to container ships, to wastewater treatment plants. Drawing on the theory of plural rationality, we show how the production and consumption of food and water in households and societies can be understood as occurring according to four institutionally induced styles: four basic ways of understanding the world and acting within it; four ways of living with one another and with nature. That there are four is due to the theory of plural rationality at the core of this chapter.

AbstractWe investigate the network topology of a comprehensive data set of the world-wide population of corporate entities. In particular, we have extracted information on the boards of all companies listed in Bloomberg’s archive of company profiles in October, 2015, a total of almost 100,000 firms. We provide information on board membership overlaps at various levels, and, in particular, show that there exists a core of directors who accumulate a large number of seats and are highly connected among themselves both at the level of national networks and at the worldwide aggregated level.

AbstractAging research is a very popular field of research in which the deterioration or decline of various physiological features is studied. Here we consider the molecular level, which can also have effects on the macroscopic level. The proteinogenic amino acids differ in their susceptibilities to non-enzymatic modification. Some of these modifications can lead to protein damage and thus can affect the form and function of proteins. For this, it is important to know the distribution of amino acids between the protein shell/surface and the core. This was investigated in this study for all known structures of peptides and proteins available in the PDB. As a result, it is shown that the shell contains less susceptible amino acids than the core with the exception of thermophilic organisms. Furthermore, proteins could be classified according to their susceptibility. This can then be used in applications such as phylogeny, aging research, molecular medicine, and synthetic biology.

Marc Shapiro puts an explicit contemporary context on this remarkable collection of sources that disagreed with one part or other of Maimonides' Thirteen Principles—the beliefs Maimonides asserted were absolutely necessary to be considered a believing Jew and to attain the World to Come. By showing the extent to which past authors disagreed with those Principles, Shapiro seeks to debunk assertions by contemporary writers that place those Principles at the core of Orthodox belief.

AbstrakPenduduk Lundayeh terdapat di Tenom, Sipitang dan Long Pa Sia, di sepanjang pantai barat Sabah, Malaysia. Bentuk dan sistem tarian Lundayeh telah melalui perubahan dan variasi sejak kewujudan mereka di Borneo. Artikel ini mengkaji dalam pelbagai aspek, termasuk muzik, pakaian, pergerakan, fungsi dancerita-cerita daripada tarian tradisional yang diamalkan dalam masyarakat Lundayeh hari ini di Kemabong, Sabah. Tarian tradisional Lundayeh yang masih diamalkan berdasar terutamanya kepada aspek budaya, sosial dan agama hidup Lundayeh. Kajian ini membawa kepada penemuan corak pemikiran, falsafahhidup dan perspektif dunia Lundayeh yang dipengaruhi oleh agama dan budaya purba mereka. Tarian tradisional Lundayeh berfungsi sebagai satu saluran untuk memahami sifat orang Lundayeh sebagai salah satu kumpulan etnik kecil di dunia. Pemahaman tentang sifat orang Lundayeh akan terus menyumbang ke arah perkongsian dan penemuan dalam dimensi ilmu kemanusiaan yang baru.   AbstractLundayeh populations are found in the areas of Tenom, Sipitang and Long Pa Sia, along the west coast of Sabah, Malaysia. Lundayeh dance forms and systems have gone through changes and variations since their existence in Borneo. This paper looks into a variety of aspects, including music, costumes, movements, functions and stories of the traditional dances practiced in today’s Lundayeh communities in Kemabong, Sabah. The surviving traditional dances found to have stemmed from the core of Lundayeh cultural, social and religious aspects of life. The study leads to the discovery of the thinking patterns, life philosophies and world perspectives of Lundayeh that are strongly influenced by their religion and ancient culture. Dance music ultimately serves as a tool to understand the nature of Lundayeh people as one of the minor ethnic groups in the world. The understanding of the nature of Lundayeh would further contribute toward sharing and discovering another dimension of human knowledge and wisdom.

Forty years ago, in his seminal essay, 'The Whites of Their Eyes', Stuart Hall admonished the left for its – our – collective failure in figuring out how to fight back against racism effectively. Sadly, his criticism is no less valid today than it was then, and we still have a lot to learn about how to defeat racism once and for all. We've known for more than a century that this thing we call 'race' isn't a scientifically valid phenomenon – and yet it continues to function perfectly well in the world as if it is one anyway. As Hall noted in a 2011 interview, the mere act of unmasking essentialisms and deconstructing binaries doesn't stop them from 'roaring away' in the world, completely undisturbed by our analytic prowess. This essay takes stock of the current state of anti-racist struggles (at least in the US) and offers a critical analysis of how and why our current efforts to combat racism continue to be so ineffective.

Analyzed is one of the most comprehensive modern approaches to the problem of the existence of evolution of human society as such and of specific human communities, i.e. “General Theory of Historical Development” by American historian and sociologist Stephen Sanderson. While agreeing, in general, with its main ideas, we believe that it is important to note that the issue of existence of individual communities demonstrating devolution (regression to an earlier historical state), stagnation or degeneration at certain historical stages is practically ignored in the framework of the theory under consideration. This creates its vulnerability in the face of specific empirical data, indicating a deviation from the evolutionary trend. We believe that overcoming this theoretical difficulty is possible in the process of comprehending the theory of S. Sanderson in the context of ideas of the world-system approach of Immanuel Wallerstein. We want to show that examples of devolution, stagnation and degeneration of societies do not deny general progressive evolutionary tendencies, characteristic for the world-system as a whole, but only indicate the transition of a particular society to a lower level within the world-system (from the core to the semi-periphery, or from the semi-periphery to the periphery).
