The purpose of this paper is to highlight the influence of the late Heinz von Foerster in the life of an admirer and friend who remains a leader in the field of family therapy.

The approach is autobiographical. The method is (loosely) process recall and personal theoretical reflection. Objectives are achieved by organizing major tenets of von Foerster's constructivism into personal categories of meaning.

Findings included a deep philosophical influence on the author's professional life; an abiding impact on his personal life; and a durability of von Foerster's ideas across disciplines, time, and the ever‐changing theories and politics of the mental health profession.

This paper adds value to the social sciences in general, and to the field of family therapy in particular, because it highlights the interconnectedness of person and profession and the confluence of the messenger/message. Some might say this is cybernetics in vivo. There may be little that is “new” in this paper in terms of theoretical constructs, but the autobiographical nature of the reflections may be its most valuable contribution to others struggling with such concepts.

To assess the recent influence of Gregory Bateson on publication within the field of psychotherapy.

Literature survey of all accessible literature from 1996 to 2006, utilizing citation search engines for identification purposes followed by reading and evaluating the most relevant publications.

Research that investigates Bateson's ideas is promising but scarce, and theoretical development that builds on his constructs is rare. Apart from frequency in citation, his contributions seem to be more durable than generative.

Owing to the volume of data, a complete survey of literature was impossible, focusing our work on psychotherapy for this paper. Other projects surveying fields such as management and sociology should be undertaken to assess Bateson's influence.

Practice should be tied to theory‐building and ongoing research rather than nostalgia, myopic commitment to ideals, or myth. Purposeful commitment to cybernetic theory and practice development is needed.

Few literature reviews have attempted to conduct a survey this broad. It is believed this has been successful in addressing actual publication practices.

This chapter documents how eugenics, scientific racism, and hereditarianism survived at Harvard well into the interwar years. In the late 1920s and early 1930s, Thomas Nixon Carver and Frank W. Taussig published works in which they established a close nexus between an individual’s economic position and his biological fitness. Carver, writing in 1929, argued that social class rigidities are attributable to the inheritance of superior and inferior abilities on the respective social class levels and proposed an “economic test of fitness” as a eugenic criterion to distinguish worthy from unworthy individuals. In 1932, Taussig, together with Carl Smith Joslyn, published American Business Leaders – a study that showed how groups with superior social status are proportionately much more productive of professional and business leaders than are the groups with inferior social status. Like Carver, Taussig and Joslyn attributed this circumstance primarily to hereditary rather than environmental factors. Taussig, Joslyn, and Carver are not the only protagonists of our story. The Russian-born sociologists Pitirim Alexandrovich Sorokin, who joined the newly established Department of Sociology at Harvard in 1930, also played a crucial role. His book Social Mobility (1927) exercised a major influence on both Taussig and Carver and contributed decisively to the survival of eugenic and hereditarian ideas at Harvard in the 1930s.

Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

Presents the scientific methodology from the enlarged cybernetical perspective that recognizes the anisotropy of time, the probabilistic character of natural laws, and the entry that the incomplete determinism in Nature opens to the occurrence of innovation, growth, organization, teleology communication, control, contest and freedom. The new tier to the methodological edifice that cybernetics provides stands on the earlier tiers, which go back to the Ionians (c. 500 BC). However, the new insights reveal flaws in the earlier tiers, and their removal strengthens the entire edifice. The new concepts of teleological activity and contest allow the clear demarcation of the military sciences as those whose subject matter is teleological activity involving contest. The paramount question “what ought to be done”, outside the empirical realm, is embraced by the scientific methodology. It also embraces the cognitive sciences that ask how the human mind is able to discover, and how the sequence of discoveries might converge to a true description of reality.

In the second part of this report the action of nitrogen peroxide on flour is discussed at some length in an account of a series of researches that have been carried out by DR. MONIER‐WILLIAMS. His conclusions may be briefly stated as follows. The maximum bleaching effect is obtained when each kilogram of flour is treated with from 30 to 100 cubic centimetres of nitrogen peroxide. The bleaching effect becomes more pronounced after keeping for several days. The amount of nitrous acid or nitrites that are present in bleached flour corresponds to about 30 per cent. of the total nitrogen absorbed, the proportion of nitrites present remaining nearly constant after the lapse of several days in the more slightly bleached samples. After the lapse of a short time it is still possible to extract about 60 per cent. of the nitrogen absorbed by the flour by means of cold water, but after several days the nitrogen that can be extracted by this means decreases. This may perhaps be attributed to the “absorption” of nitrous acid by the glutenin and gliadin. In highly bleached flour (300 cubic centimetres of nitrogen peroxide per kilogram of flour) a considerable increase in the amounts of soluble proteins and soluble carbohydrates takes place. In highly bleached flour, after some time, about 6 or 7 per cent. of the nitrogen introduced as nitrogen by the nitrogen peroxide is absorbed by the oil, which acquires the characteristics of an oxidised oil. No evidence is forthcoming as to the formation of diazo compounds nor the production of free nitrogen. Bleaching was found to exercise an inhibitory action on the salivary digestion of flour.

Purpose – This chapter examines how sentiment analysis and web-crawling technology can be used to conduct large-scale data analyses of extremist content online.

Methods/approach – The authors describe a customized web-crawler that was developed for the purpose of collecting, classifying, and interpreting extremist content online and on a large scale, followed by an overview of a relatively novel machine learning tool, sentiment analysis, which has sparked the interest of some researchers in the field of terrorism and extremism studies. The authors conclude with a discussion of what they believe is the future applicability of sentiment analysis within the online political violence research domain.

Findings – In order to gain a broader understanding of online extremism, or to improve the means by which researchers and practitioners “search for a needle in a haystack,” the authors recommend that social scientists continue to collaborate with computer scientists, combining sentiment analysis software with other classification tools and research methods, as well as validate sentiment analysis programs and adapt sentiment analysis software to new and evolving radical online spaces.

Originality/value – This chapter provides researchers and practitioners who are faced with new challenges in detecting extremist content online with insights regarding the applicability of a specific set of machine learning techniques and research methods to conduct large-scale data analyses in the field of terrorism and extremism studies.
