This paper presents a self‐consistent I‐V simulation technique for an RTD with defect wells placed inside the barriers. The motivation of this paper was to model the excess valley current by a defect‐assisted tunneling mechanism. We have calculated the transmission coefficients and I‐V characteristics self consistently with Poisson's equation coupled to quantum mechanical tunneling through the barrier. The shape of transmission coefficient was broadened and greatly enhanced in the off‐resonance region when the defect well was introduced in the barriers. Our results gave a good qualitative estimation of the valley current and the peak to valley current ratio (PVCR).

George Spencer Brown is best known for his book Laws of Form, which elaborates a primary algebra of distinctions and forms capable of dealing with self-referential equations reflective of paradoxes in logic. The book has received little attention in mathematics, but it has greatly influenced cybernetics, communications, and ecological theories. But Spencer Brown also published poetry and stories, often under different names, and he practiced as a psychotherapist. Our chapter elaborates the utility of Laws of Form relating to organizational paradox before considering Spencer Brown’s other works in relation to his mathematics. Invoking philosophy, psychoanalysis and art, we suggest that these indicate a further distinction that sets all forms against the “nothing”: a wholeness or unity from out of which all distinctions, all words, meaning and life – but also all silence, nonsense and death – emerge in paradoxical opposition. Reading Spencer Brown not through the prism of mathematics, but as an evocative invitation to engage with the fissures that animate art and human life, highlights the paradoxical interplay of organization and violence; and how tragedy, suffering, sympathy and love should be more prominent in organizational research.

What sets health sciences librarians apart from other academic librarians when it comes to partnering with health-focused innovators? Do health-related innovators have different information needs or space requirements? This chapter illustrates some of the major issues and topics health sciences librarians consider as they offer information services to entrepreneurs and innovators. Health sciences innovators must be aware of relevant policies and laws such as HIPAA, the Health Insurance Portability and Accountability Act of 1996. They also need to meet federal safety regulations required by the Food and Drug Administration; moreover, device materials must be biocompatible. Those developing therapeutic games and apps in this arena need to ensure their products are supported by current literature and scientific evidence. In many cases, these new technologies require clinical trials and testing to ensure their safety and efficacy. Health sciences librarians guide innovators to relevant resources, knowledge, and experts on these and other topics. This navigator role is extremely valuable to students, who may not understand the healthcare landscape and its processes. Additionally, librarians assist innovators with identifying dissemination venues for their scholarly output. They provide instruction and guidance on how to write and tailor conference proposals to meet specific professional association criteria. A retired health sciences library director shares her experiences. Tips and lessons learned are highlighted so others may gain an understanding of the unique information needs of health innovators.

It must be difficult for many to contemplate the numerous changes in progress and projected without wondering why it all has to happen now. Of course, there have always been with us those who would change everything, even those who would spoil; all seemingly unable to leave anything alone; unwillingly to let us be for what we are. Then there are those who dislike change of any kind in their familiar environment and strangely, children are the most conservative of us all, and others who do not object to change when it is necessary, but only when it is change merely for the sake of change. The changeover to the metric system, or to use one of the grating terms of the new technological language, metrication, must be accepted as a natural sequence to decimal currency and advances in industry. A revolution in weights and measures, it will indeed present very great problems throughout the country and at all levels, which will dwarf those presented by the switch to decimal coinage, for at worst, these may be just confusing to the general public and a price‐raiser in small‐value commodities, despite assurances to the contrary.

Forty‐six milks were submitted for analysis. Five of these were reported against for added water or fat deficiency. The leaky churn appeared on the scene in one case, but this did not save the vendor from fine and costs amounting to over thirteen pounds.

The purpose of this paper is to find a leading idea of the mid-twentieth century, demonstrating the pervasive nature of some concepts belonging to second-order systems theory. To achieve this objective, the paper looks at the art and literature of this era, to identify the principles developed by Luhmann in his late works. In particular, Escher’s drawings, Calvino’s stories and Luhmann’s concepts seem to express, in different ways, the same functioning mechanism of the complex social system.

With reference to theoretical approach and methodology, this paper carries out an interdisciplinary demonstration by alternative modes of logos and mythos. Some of the pillars of general systems theory are examined through the logical articulation of concepts developed by Spencer-Brown, von Foerster, and first of all through the late works of Luhmann, as well as through the analysis of Escher’s artworks and Calvino’s literary works. This paper interprets these artistic and literary works using cybernetic principles and systemic concepts, in particular, “two-sided forms,” “system–environment differentiation” and “second-order observation.”

In general, the main finding is the similarity of fascination with paradoxes and forms, with post-ontological reasoning, in twentieth century. The result of the cross-reading of Escher, Calvino and Luhmann reveals the presence of what Simmel called the “hidden king”: a philosophical paradigm of an era. In mid-1900s, this leading idea seems to express itself in the discoveries of biology and cybernetics, such as in Luhmann’s theory, art and literature. Escher’s drawings, Calvino’s stories and the concepts of Luhmann are projections of second-order system theory, in its constructivist value.

The originality of this paper lies mainly in the demonstration of theoretical concepts through the alternative modes of logos and mythos. These reflections can provide a new perspective to investigate social sciences from a cultural angle. This particular approach allows a deep awareness of the theory. The concrete value is to provide a better understanding to manage complexity.

The Professors of the Imperial College of Science and Technology have addressed to Lord Crewe, the Chairman of the Governors of the College, a memorial urging the necessity of the encouragement of science and of research. In commenting upon this document the Journal of Chemical Technology observes that “a satisfactory feature of the memorial is the recognition on the part of the signatories that scientific education should be on broad lines.” “We have always contended that an indispensable preliminary to a professional career should be a thoroughly sound general education. Whether or not the study of science is the best kind of study may be a debatable point, but it is certain that exclusive attention to science is thoroughly bad. A man's mind is narrow when he is unable to recognise the importance of things outside his own particular sphere of action, and it is precisely this state of mind that the exclusive study of science tends to produce. It is, therefore, the more necessary, in seeking to secure greater attention to scientific studies in the reform of our educational system, to take care that nothing be done which may curtail the period required for the acquisition of general knowledge. It is far better to delay than to hasten specialisation. A step in the right direction has been made when scientific men themselves state that they do not believe that “an education which includes good teaching of science need be a narrow education,” but we wish that this opinion had been positively rather than negatively expressed. The memorial refers to the “lethargy, misconception, and ignorance” of the public regarding national education. It is pertinent here to remark that when anything goes wrong and no particular individual or individuals can be held to be, or will acknowledge themselves to be, responsible, the “public” is blamed; the public being everybody with the exception of the denunciator and his friends. In the present instance the fault is not, even for the greater part, with the people. They are, naturally enough, interested in education only in so far as it is expressed in terms of school and college accounts and of wage‐earning capacity. Of the bearing that improvement in education and the advancement of physical science has on the welfare of the community the average man knows little and cares less. He has to be educated in the value of education. He is not, and probably never will be, interested in education as an abstract good. What interest he has in it is purely utilitarian. If he sees that the knowledge which he himself does not possess carries with it but doubtful prospects for the future, poor remuneration in the present and a social position little better than his own, he is unlikely to be impressed with the value of education. The fact is that there is a lamentable want of opportunity for the intellectual classes in this country and until this state of things is remedied the public will continue to display—and with every justification — “lethargy, misconception, and ignorance” in respect to national education.
