The removal of the udders from two cows known to be infected with Br. melitensis (abortus) was followed in both cases by a reduction in agglutination titre. In the one case, the agglutination titre declined from 1:600 to a value within the negative range, 1:25, and in the other the very high agglutination titre (1:28000) rapidly declined to a point just within the positive range, 1:100.

Expressions are combinations of operators and operands which are evaluated to produce a value of a specific type. Infix operators require two operands with an operator written between them. A prefix operator requires one operand with an operator written before it. (The expression syntax starts on page 208.) Evaluation proceeds from left to right, governed by the precedence of the operators. The lowest numbered precedence as shown in Table 14.1 is evaluated first. Operators in the same row have the same precedence. Expressions enclosed by parentheses are evaluated before being treated as a single operand. An operand between two operators of different precedence is bound to the operator with the higher one; e.g., −10*20 means (−10)*20. An operand between two operators of the same precedence is bound to the one on the left; e.g., 10/20 * 30 means (10/20) * 30. Exercise 14.1 Work out the intermediate steps for this expression: … −2/(4+4)*5+6… When a null value is encountered in an expression where a non-null is expected, evaluation is short circuited and a null answer is produced. Otherwise, all expressions are fully evaluated even when the outcome is known after partial evaluation. Exercise 14.2 Can you think of an expression that does not require complete evaluation to get the correct answer? The operands of an operator must be compatible with the operator and with each other. Operands can be compatible without having identical types and are compatible when any of these conditions are satisfied: • The types are the same. • One type is a subtype of the other (e.g., one is a number and the other is an integer. • Both types are strings. • Both types are binaries. • Both types are arrays which have compatible base types and identical bounds. • Both types are bags which have compatible base types. • Both types are lists which have compatible base types. • Both types are sets which have compatible base types. Operations are organized by the kind of result they produce, namely: numeric, boolean or logical, string or binary, or aggregate.

AbstractThe trend toward the concept of humanity in political theory has arisen largely as a reaction against the mistreatment of vulnerable people such as immigrants. The issue of immigrants’ vulnerability has led political thinkers to ponder on how to apply the principle of humanity to the question of the treatment of immigrants. I would like to address this matter by examining two questions: what is humanity, is it a value property, or a virtue? Does it really matter if the means by which an immigrant immigrates is demeaning to his own humanity as a person? The most common or intuitive reply to these questions would probably be: ‘humanity’ is simply a value-bestowing property, so regardless of immigrants’ actions they are owed respectful treatment. The aim of this paper is to emphasise instead that ‘humanity’ should be conceived as a virtue of actual commitment to act on moral principles. I explore three different meanings of humanity. First, I discuss ‘humanity’ as the common ownership of the earth. Second, I discuss ‘humanity’ as a value property. Third, I discuss humanity as a virtue of acting, on the one hand, with humanity, and on the other hand, on moral principles.

With the rapid development of VDSL (Very high-bit-rate Digital Subscriber Line) system, not all the tones have the same margin. In order to cope with the slowly-changing channel, Bit Swap is utilized to swap the tone pairs: the one has a high margin while the other one has a relatively low margin. Although the Bit Swap has been proposed before, there is no Bit Swap established on EOC and the proposed scheme also implements coarse and fine SNR margin tuning. The paper presents the architecture and process of Bit Swap based on EOC and also proposes the method to adjust the margin for tones calculated to be swapped. After thoroughly tested, the test results show that the proposed scheme functions well. Compared with the scheme without Bit Swap, it greatly improves the performance against crosstalk noise and can reduce the RS errors to zero.

The so-called “Win-Continue, Lose-Reverse” (WCLR) rule is a simple iterative procedure that can be used to choose a value for any numeric variable (e.g., setting a price or a production level). The rule dictates that one should evaluate the effect on profits of the last adjustment made to the value (e.g., a price variation), and keep on changing the value in the same direction if the adjustment led to greater profits, or reverse the direction of change otherwise. Somewhat surprisingly, this simple rule has been shown to lead to collusive outcomes in Cournot oligopolies, even though its application requires no information about the other firms’ profits or choices. In this paper, we show that the convergence of the WCLR rule toward collusive outcomes can be very sensitive to small independent perturbations in the cost functions or in the income functions of the firms. These perturbations typically push the process toward the Nash equilibrium of the one-shot game. We also explore the behavior of WCLR against other strategies and demonstrate that WCLR is easily exploitable. We then conduct a similar analysis of the WCLR rule in a differentiated Bertrand model, where firms compete in prices.

Indonesia is a pluralistic country (diverse) in terms of ethnicity, religion, culture, language and social system. This diversity is a blessing that is given as a potential wealth of the nation. On the one hand, this potential can be managed to strengthen nationality and people's welfare, but on the other hand, it can be a potential conflict that can weaken and even solve (disintegration) of nationalism if it is not managed properly. Indonesia has a variety of local wisdom as invaluable social capital. One of them is Pela in Maluku which has a value system that is capable of marching and strengthening (integration) nationalism. The Pela value system has at least four functions that are able to effectively integrate (social cohesion) and strengthen national potential at the local (regional) level, especially in Maluku.

In the monograph, through the method of ethical questioning, a special place of open scientific thinking in the development of national culture is revealed. On the one hand, culture is conceived as a determinant of personal self-determination, which forms a person as an elementary unit and measure of a value system, on the other hand, it is an object of theoretical reflection, a complex systematic phenomenon causing social changes and the course of history. The book is written for students of social and humanitarian disciplines, scientists, philosophers and educators.В монографии посредством этического вопрошания раскрывается особое место открытого научного мышления в становлении отечественной культуры. С одной стороны, культура мыслится в качестве детерминанты личностного самоопределения, формирующей личность как элементарную единицу и мерило ценностной системы, с другой — является объектом теоретической рефлексии, сложным системным феноменом, обуславливающим социальные изменения и ход истории. Книга адресована студентам социальных и гуманитарных дисциплин, ученым, философам и педагогам.

The hypoxic and dry environment of the high mountains seems to select eggshells with porosities appropriate for the altitudinal level. At moderate altitudes, the conservation of water takes precedence over the oxygen-supply gradient. At very high altitudes there is a compromise between reducing water loss on the one hand and the defense of the oxygen supply to the embryo on the other.

AbstractMany of us are all too familiar with the experience of taking pleasure in things we feel we ought not, and of finding it frustratingly hard to bring our pleasures into line with our moral judgements. As a value dualist, Kant draws a sharp contrast between the two sources of practical motivation: pleasure in the agreeable and respect for the moral law. His ethics might thus seem to be an unpromising source for help in thinking about how we can bring our agreeable pleasures into line with our moral values. But I argue that a careful reading of Kant’s texts reveals a helpfully realistic view about the extent to which we can modify our agreeable pleasures. On my interpretation, Kant shows us how to hold together two seemingly incompatible ideas: on the one hand, that pleasure in the agreeable is resistant to rational direction, and on the other hand, that we can cultivate these pleasures with a view to ethical self-transformation.

T he present paper is intended to be the first of a series on the Anatomy of the Vertebrate Skull; and I have chosen the cranium and face of the Ostriches as a startingpoint, principally because of the mid position of these birds in the vertebrate subkingdom, and, in some degree also, because of their generalized character. Indeed, to any one familiar, on the one hand, with the structure of the skull in the higher mammalian types, and on the other with that of the osseous fishes, the skull of an Ostrich is interesting and important in a very high degree; serving, at it does, as a key to open up the meaning of parts so extremely unlike as the true homologues in the Fish and in the Mammal often are. And further, whilst aiding the anatomist in revealing the true morphological counterparts in the highest, as compared with the lowest types, the skull of an ostrich does also form a link of the utmost value for connecting together that of a cold-blooded and that of a warm-blooded creature.


On the afternoon of Friday 22 July, a premiere of films was given at the Royal Festival Hall and was followed by a Reception at Tea when Mr F. J. Stephens acted as host for the Royal Dutch/Shell Group of Companies. The programme was introduced by Sir Cyril Flinshelwood, President of the Royal Society, who said: . ‘In the Charter of the Royal Society the improvement of natural knowledge is coupled with that of the useful arts. Now the tradition fortunately exists in this country of good relations between the great industries on the one hand and the cultivators of natural science on the other: or I would prefer to say the very nebulous line that there is between these two branches of activity is evidence of the fact that this part of the Charter has in fact not been ignored. That the Shell Group of Companies, one of the greatest and most important, has made the extremely generous gesture of preparing the very splendid film that you will presently see in honour of the Tercentenary of the Royal Society proves that the tradition that I have spoken of is alive and vigorous. ‘You will presently agree that the film also demonstrates the very high quality of the Film Unit which the Company has maintained for, I understand, something over a quarter of a century.
