Weaving Algebraic Patterns

The Analytical Engine has a startling place in the history of computing. To the best of our knowledge, no machine had ever before been conceived along its lines. More remarkably, some of its key principles of design would actually be reinvented a century later by people who were, apparently, ignorant of it. If imitation is the sincerest form of flattery, then so is re invention or re discovery, at least when born from ignorance. It tells us much about how ahead of one’s time the original creator was. This reinvention of Babbage’s idea was particularly poignant because it would become the fount of fruitful and rich phylogenetic pathways in the later evolution of the digital computer and the emergence of computer science. Dissatisfaction is a prime generator of the creative urge, dissatisfaction with the status quo and the desire to change it to something better. Charles Babbage was unhappy with the waste of human mental labor in computing mathematical tables, which led to his desire to free human beings from this tedium—hence, the Difference Engine. However, the Difference Engine produced its own discontent. As Luigi Frederico Menabrea (1809–1896), an Italian military mathematician (and, later, prime minister of Italy) would explain apropos the Difference Engine, its use was limited to one particular kind of computation. It could not be applied to the solution of “an infinity of other questions” of interest to mathematicians. It was this limitation and the attendant discontent that led Babbage to conceive the machine he called the Analytical Engine, the operation of which he believed would encompass the full range of algebraic problems. The Difference Engine was not general enough. Babbage desired a computing engine that could range over the whole of “mathematical analysis.” As he explained in a letter to the Earl of Rosse, then president of the Royal Society, his Analytical Engine would have the power to perform the “most analytical complicated operations.” Here, then, is Babbage’s promise: a mathematical machine with “nearly unlimited” powers. Babbage’s name for his new machine is significant.

In the history of women's life, the woman has never cracked from the wild cry of helplessness. Woman always become victim of men’s egoism, marginalized, hurt, unfettered, fooled and never appreciated the presence and role. This situation troubles many intellectual Muslims who have perspective that Islam teaches equality, equality for all human beings in the world. The difference in skin color, race, tribe and nation, as well as gender does not cause them to get the status of the different rights and obligations. The potential and the right to life of every human being and the obligation to serve the Lord Almighty is the same. Indeed, all human beings, as caliph in the world, have the same obligation, namely to prosperity of life in the world. No one is allowed to act arbitrarily, destroying, or hurt among others. They are required to live side by side, united, and harmonious, help each other and respect each other. However, that "demand" never becomes a reality. The differences among human identities become a barrier and the cause of divisions. For them, those who are outside environment, different identities are "others" who rightly do not need them "know". The difference of identity has become a reason to allow "hurt" each other. Several intellectual Muslims who recognize the wrong (discrimination against women), and then they attempt to formulate a movement for women's liberation. All the efforts have been done on the basis of awareness that arbitrary action by any person can never be justified. They also realize, that the backwardness of women are "stumbling block" that will lead to the resignation of a civilization. However, this struggle found a lot of challenges; including the consideration of "insubordination" to conquer the power of men, despite it had done by using many strategies. Starting from the writing of scientific book and countless fiction themed women has been published in order to give awareness of equality between men and women. This paper seeks to reexamine the process of the empowerment struggle to give a brand new concept, so that the struggle of women empowerment is not as insubordination and curiosity process in an attempt to conquer the male. Through approach of literature review and observations on the relationship between men and women, the writer finally concluded that the movement of Islamic feminism is not a movement to seize the power of men, but an attempt to liberate women from oppression so that they get the rights of their social role, giving freedom for women to pursue a career as wide as possible like a man, without forgetting a main duty as a mother: to conceive, give birth and breastfeed their children.

Abstract Objective As adolescence is a stage in which human beings face once throughout a lifetime and it is the experimental period for this reason risky sexual behavior is common among young people, and it has several sexual and reproductive health consequences. But it doesn’t get enough attention the status of risky sexual behavior practice and factors’ contributing to it, so this study aimed to identify the prevalence of risky sexual behavior and factors associated with it. Results From the total respondents 115 (23.7%) had history of sexual intercourse and the mean age for sexual initiation is 15.48 ± 1.99 year. From whom 110 (98.2%) had sexual contact below the age of 18 and only 68 (60.8%) initiate first sex by their own willing. Overall 97 (19.6%) had practiced risky sexual behaviors. Students not facing peer pressure were 0.36 times less likely to develop risk sexual behavior (AOR = 0.357, 95% CI 0.172, 0.744).

2. Action of Bisulphide of Carbon upon Amylamine . In a note on the alleged transformation of thialdine into leucine, addressed to the Royal Society about eighteen months ago, I alluded to a crystalline substance observed by Wagner when submitting amylamine to the action of bisulphide of carbon. This substance was not analysed, but considering its mode of formation, Wagner suggested that it might possibly be thialdine. A superficial comparison of the properties of thialdine with those of the substance produced by the action of bisulphide of carbon upon amylamine, enabled me at once to recognize the difference of the two bodies; and satisfied with the result, I did not at the time examine more minutely into the nature of the latter substance.

Summary This article examines the legacy of Charles Montagu, Lord Halifax, within the history of science. Although he was President of The Royal Society from 1695 to 1698, Montagu is best known for his political career and as a patron of the arts. As this article shows, Montagu's own scientific interests were limited and his chief significance to the history of science lies in his friendship with a later President, Isaac Newton. It is argued, firstly, that their relationship had important, though indirect, consequences for The Royal Society and, secondly, that its treatment by historians of science has been revealing of changing views of the status of science and its practitioners. Particular attention is given to the approaches of the first generation of Newtonian scholars and biographers in the 19th century.

AbstractIncreasingly, preprints are at the center of conversations across the research ecosystem. But disagreements remain about the role they play. Do they “count” for research assessment? Is it ok to post preprints in more than one place? In this paper, we argue that these discussions often conflate two separate issues, the history of the manuscript and the status granted it by different communities. In this paper, we propose a new model that distinguishes the characteristics of the object, its “state”, from the subjective “standing” granted to it by different communities. This provides a way to discuss the difference in practices between communities, which will deliver more productive conversations and facilitate negotiation on how to collectively improve the process of scholarly communications not only for preprints but other forms of scholarly contributions.

Science fiction (SF) emerges as a distinct literary and cultural genre out of a familiar set of world-famous texts ranging from Mary Shelley’s Frankenstein (1818) to Gene Roddenberry’s Star Trek (1966–) to the Marvel Cinematic Universe (2008–) that have, in aggregate, generated a colossal, communal archive of alternate worlds and possible future histories. SF’s dialectical interplay between utopian optimism and apocalyptic pessimism can be felt across the genre’s now centuries-long history, only intensifying in the 20th century as the clash between humankind’s growing technological capabilities and its ability to use those powers safely or wisely has reached existential-threat propositions, not simply for human beings but for all life on the planet. In the early 21st century, as in earlier cultural moments, the writers and critics of SF use the genre’s articulation of different societies and different possible futures as the occasion to reflect on our own present, in ways that range from full-throated defense of the status quo to the ruthless denunciation of all institutions that currently exist in the name of some other, better world. SF’s global popularity has grown to the point where it now looms quite large over cultural production generally, becoming arguably the most popular narrative genre in existence, particularly in the sorts of SF action spectacles that have dominated the global box office of the first two decades of the 21st century. It has also become increasingly difficult to tell the difference between the things we used to think of as SF and the advanced communication, transportation, and entertainment technologies that have become so ubiquitous and familiar that we now take them for granted, as well as the growing prevalence of political, economic, and ecological crises now erupting out of the pages of our science fictions, like our very worst dreams come to life.

AbstractThis article is an essay on directions and methodology in computer-science oriented research on scientific discovery. The essay starts by reviewing briefly some of the history of computing in scientific reasoning, and some of the results and impact that have been achieved. The remainder analyses some of the goals of this field, its relations with sister fields, and the practical applications of this analysis to evaluating research quality, reviewing, and methodology. An earlier review in this journal (Kocabas 1991b) analysed scientific discovery programs in terms of their designs, achievements and shortcomings; the focus here is research directions, evaluation and methodology, all from the viewpoint of computer science.

Abstract This research focused on recognition the difference between trauma and attention-deficit/hyperactivity disorder (ADHD) among children and youth in an urban school environment. The objective of this exploratory research was to gain a deeper understanding of the current challenges and barriers relating to assessments and treatments of children with a history of trauma and a putative diagnosis of ADHD. This research study reviewed a representative sample of qualitative observations made by clinicians who worked with children in urban school districts in the San Francisco Bay Area in northern California. In addition, we assessed secondary information of hand-written notes from past clinicians who previously worked in these same schools. We utilized reflexivity (researcher’s views/experiences) methods and framed within an evolutionary perspective, specifically the concept of the flight-freeze response to violence; this perspective offers us insight into how we as human beings react and respond to threats and violence in our lives. We concluded that among our sample, a significant portion of those diagnosed with ADHD had past trauma and trauma symptoms, and that there was noticeable overlap of symptoms that could be attributed to either ADHD or post-traumatic stress disorder (PTSD). This screening for trauma is critical for matters relating to the development of effective and appropriate interventions. We believe that conducting past family histories, and specifically conducting assessments of any history of past trauma, may help reduce the likelihood of misdiagnosing and may assist in being able to administer more effective treatments.

AbstractSurrogacy is a social practice aimed at the procreation of human beings through the use of biomedical technologies. It includes the willingness of a woman to carry out a pregnancy and give birth to a child, with whom she has no genetic link, which will be immediately entrusted at birth to the people who wanted and commissioned it, known as the intended parents. A multi-million transnational market has flourished around this kind of arrangement, with the national legal frameworks being very different from each other and constantly changing. The surrogate’s revenue varies considerably from country to country, as does the price that the aspiring parents pay. This chapter aims to introduce readers to the topic by providing the main coordinates of the phenomenon: how the medical-procreative procedure takes place, what the commercial transaction consists of; the history of this market, the similarity of surrogacy with other procreative practices, and the difference with other assisted procreation practices; the variety of regulatory frameworks, the flexibility of the market according to the logic of globalization; the health risks and the inevitability for the child of the fracture with the “environment” in which he began his psychophysical development.
