AbstractThe article connects historical developments in analytics with contexts of today and school experiments: Woehlk test and Fearon’s test are historically known as the reactions of lactose and maltose with ammonia and methylamine, respectively. Both lead to characteristic red dyes whose formation and structural formulae had not been of interest or had even been reported incorrectly until 2015. Even though these tests, developed in the first half of the twentieth century, are obsolete in medicinal analysis today, they pose interesting experiments for school chemistry, when investigating the topic of macromolecules or sugars. In an inquiry or context-based teaching approach, tests visualizing different lactose concentrations in different dairy products would fit into the contexts milk and chemical detection of diseases. The experiments can also be used in a historically based problem-oriented approach in which the scientists, their work and lives can be the central perspective. As both methods of analysis result in brightly colored solutions, they are easily interpretable as well as aesthetically appealing to students. As the test developed by Fearon is quicker and makes use of less dangerous chemicals, it is the one to be preferably used in school.

The Subject

The nature of social organization during the Orcadian Neolithic has been the subject of discussion for several decades with much of the debate focused on answering an insightful question posed by Colin Renfrew in 1979. He asked, how was society organised to construct the larger, innovative monuments of the Orcadian Late Neolithic that were centralised in the western Mainland? There are many possible answers to the question but little evidence pointing to a probable solution, so the discussion has continued for many years. This paper takes a new approach by asking a different question: what can be learned about Orcadian Neolithic social organization from the quantitative and qualitative evidence accumulating from excavated domestic structures and settlements?In an attempt to answer this question, quantitative and qualitative data about domestic structures and about settlements was collected from published reports on 15 Orcadian Neolithic excavated sites. The published data is less extensive than hoped but is sufficient to support a provisional answer: a social hierarchy probably did not develop in the Early Neolithic but almost certainly did in the Late Neolithic, for which the data is more comprehensive.While this is only one approach of several possible ways to consider the question, it is by exploring different methods of analysis and comparing them that an understanding of the Orcadian Neolithic can move forward.

In the last few years, it has often been said that the current fashion system is outdated, still operating by a twentieth-century model that celebrates the individualism of the 'star designer'. In I- D, Sarah Mower recently stated that for the last twenty years, fashion has been at a cocktail party and has completely lost any connection with the public and daily life. On the one hand, designers and big brands experience the enormous pressure to produce new collections at an ever higher pace, leaving less room for reflection, contemplation, and innovation. On the other hand, there is the continuous race to produce at even lower costs and implement more rapid life cycles, resulting in disastrous consequences for society and the environment.

Subordinate-deity models of ultimate reality affirm that God is Highest Being within an ultimate reality that is neither conceptually tractable nor religiously relevant. Subordinate-deity models ceded their dominance to agential-being models of ultimate reality by refusing to supply a comprehensive answer to the metaphysical problem of the One and the Many in the wake of the Axial-Age interest in that problem, but they have revived in the twentieth century due to post-colonial resistance to putatively comprehensive explanations. Subordinate-deity ultimacy models resist the Intentionality Attribution and Narrative Comprehensibility dimensions of anthropomorphism to some degree but continue to employ the Rational Practicality dimension of anthropomorphism, resulting in a strategy of judicious anthropomorphism. Variations, strengths, and weaknesses of the subordinate-deity class of ultimacy models are discussed.

European Migration

This chapter discusses social exclusion in European migration from a gendered and historical perspective. It discusses how from this perspective the idea of a crisis in migration was repeatedly constructed. Gender is used in this chapter in a dual way: attention is paid to differences between men and women in (refugee) migration, and to differences between men and women as advocates and claim makers for migrant rights. There is a dilemma—recognized mostly for recent decades—that on the one hand refugee women can be used to generate empathy, and thus support. On the other hand, emphasis on women as victims forces them into a victimhood role and leaves them without agency. This dilemma played itself out throughout the twentieth century. It led to saving the victims, but not to solving the problem. It fortified rather than weakened the idea of a crisis.

AbstractThe widespread proliferation of and interest in bracket pools that accompany the National Collegiate Athletic Association Division I Men’s Basketball Tournament have created a need to produce a set of predicted winners for each tournament game by people without expert knowledge of college basketball. Previous research has addressed bracket prediction to some degree, but not nearly on the level of the popular interest in the topic. This paper reviews relevant previous research, and then introduces a rating system for teams using game data from that season prior to the tournament. The ratings from this system are used within a novel, four-predictor probability model to produce sets of bracket predictions for each tournament from 2009 to 2014. This dual-proportion probability model is built around the constraint of two teams with a combined 100% probability of winning a given game. This paper also performs Monte Carlo simulation to investigate whether modifications are necessary from an expected value-based prediction system such as the one introduced in the paper, in order to have the maximum bracket score within a defined group. The findings are that selecting one high-probability “upset” team for one to three late rounds games is likely to outperform other strategies, including one with no modifications to the expected value, as long as the upset choice overlaps a large minority of competing brackets while leaving the bracket some distinguishing characteristics in late rounds.

Scholars interested in theorizing about political representation in terms relevant to democratic governance in mid-twentieth century America find themselves in a quandary. We are surrounded by functioning representative institutions, or at least by institutions formally described as representative. Individuals who presumably “represent” other citizens govern some 90 thousand different political units—they sit on school and special district boards, on township and city councils, on county directorates, on state and national assemblies, and so forth. But the flourishing activity of representation has not yet been matched by a sustained effort to explain what makes the representational process tick.Despite the proliferation of representative governments over the past century,theoryabout representation has not moved much beyond the eighteenth-century formulation of Edmund Burke. Certainly most empirical research has been cast in the Burkean vocabulary. But in order to think in novel ways about representative government in the twentieth-century, we may have to admit that present conceptions guiding empirical research are obsolete. This in turn means that the spell of Burke's vocabulary over scientific work on representation must be broken.To look afresh at representation, it is necessary to be sensitive to the unresolved tension between the two main currents of contemporary thinking about representational relationships. On the one hand, representation is treated as a relationship between any one individual, the represented, and another individual, the representative—aninter-individualrelationship. On the other hand, representatives are treated as a group, brought together in the assembly, to represent the interest of the community as a whole—aninter-grouprelationship. Most theoretical formulations since Burke are cast in one or the other of these terms.

Separate Discipline

With the emergence of philosophy in the nineteenth century as a separate discipline which stressed primarily questions insoluble by empirical or formal methods, Voltaire's reputation as a philosopher has gone into gradual eclipse. It has become unfashionable and degrading for philosophers to concern themselves with the practical aspects of philosophical enquiry. In eighteenth-century France, on the other hand, the identification of philosophy with science, which by twentieth-century standards had vitiated philosophical thought, produced the “philosophes” or natural philosophers who were on the whole more interested in human progress than in the progress of the human mind. And Voltaire was by popular consent the leader of this “philosophe” group, the one who had unquestionably contributed the most in the struggle to make man a happier and freer member of society. Yet, ironically, despite a lifelong effort in behalf of humanity, Voltaire's reputation as a destructive thinker has steadily grown even as the critics have pejoratively classified him as a “practical” rather than a “real” philosopher. Typical of this criticism of Voltaire is Macaulay's statement: “Voltaire could not build: he could only pull down: he was the very Vitruvius of ruin. He has bequeathed to us not a single doctrine to be called by his name, not a single addition to the stock of our positive knowledge.”

Sons and Lovers (1913) is one of D.H. Lawrence’s most prominent novels in terms of psychological complexities characteristic of most, if not all, of his other novels. Many studies have been conducted on the Oedipus complex theory and psychological relationship between men and women in Lawrence’s novels reflecting the early twentieth century norms of life. This paper reexamines Sons and Lovers from the perspective of rivalry based on Alfred Adler’s psychological studies. The discussion tackles the sibling rivalry between the members of the Morels and extends to reexamining the rivalry between other characters. This concept is discussed in terms of two levels of relationships. First, between Paul and William as brothers on the one hand, and Paul and father and mother, on the other. Second, the rivalry triangle of Louisa, Miriam and Mrs. Morel. The qualitative pattern of the paper focuses on the textual analysis of the novel to show that Sons and Lovers can be approached through the concept of rivalry and sibling Rivalry.

Zooarchaeological and molecular biological studies indicate that all domestic animals found in Japan were introduced and local domestication of wild boar and wolf is unlikely. Timing of introduction and husbandry practice for dog, pig, horse, cattle, and chicken are discussed. These main domestic species were introduced from the Chinese continent in prehistoric times, probably via the Korean peninsula. Meat of domestic animals and dairy products were not a major part of the diet until the twentieth century ad, partly because of the Buddhist prohibition of the consumption of animal meat. Zooarchaeological data from the Yayoi and Kofun period sites as well as the historical era have been gradually accumulating, helping the interpretation of textual records as well as supplementing them.

This article examines how a post-1918 Edwardian commemorative aesthetic focused on the “English Garden” was deployed in the later twentieth century as a means to establish an “informal” Empire of memory. The result is an architectural irony and a landscape at odds with the moment that made it: the post-1945 cemeteries of the Imperial War Graves Commission (IWGC) expanded the now defunct Empire’s commemorative possessions just as the actual deeds to land were surrendered. The one exception to this story of contemporaneous political withdrawal and commemorative appropriation nonetheless proves the broader point. For after the bloody imperial war fought in the South Atlantic in 1982 the Commission, at the behest of the British government, built its first and last post-1945 overseas war cemetery. And just as had been the case sixty years earlier, the form and style of this cemetery ensured it became the last outpost of an Edwardian Empire of memory.
