Relative entropy (divergence) of Bregman type recently proposed by T. D. Frank and Jan Naudts is considered and its quantum counterpart is used to calculate purity of the Werner state in nonextensive formalism. It has been observed that two different expressions arise due to two different forms of quantum divergences. It is then argued that the difference is due to the fact that the relative entropy of Bregman type is related to the first choice thermostatistics whereas one of Csiszàr type is related to the third-choice thermostatistics. The superiority of the third-choice thermostatistics to the first-choice thermostatistics has been deduced by noticing that the expression obtained by using the Bregman type leads to negative values for q ∈ (0, 1) and fidelity F smaller than 1 whereas the one obtained by using Csiszàr type is free from such anomalies. Moreover, it has been noted that these two measures show different qualitative behavior with respect to F. Contrary to the classical case, the violation of the positive definiteness of the relative entropy immediately results in a choice between the two constraints without any need of more abstract Shore–Johnson axioms. The possibility of writing a relative entropy of Bregman type compatible with the third choice has been investigated further. The answer turns out to be negative as far as the usual transformation from ordinary probabilities to the escort probabilities are considered.

  The basic foundation of this crisis actually lies with the global economic system which is based on the globalisation of the economyand financial systems. That is the foundation of the current problem.However, if we actually look at the system, this crisis is not abouta specific country or specific factor. It is actually about the globalsystem which is based on the economic globalisation system. Thequestion that comes to mind with that statement is that, will thishappen again? In my opinion it will happen again. So, this is not the final crisis, and since it is not the first crisis, it will happen again. Based on the one that we had, let us get to the content. There will be three parts to this discussion. The first one is the causes of the crisis. The second one is the impact, and the third one is the future of the economic globalisation. Is the 2008 crisis a repeat of the 1998 crisis? In fact yes, and in between, the world has seen so many crises but the big crisis happen in 1932 when the whole world was in depression. Then, we have the present crisis. These are the two major crises that involved the whole world. In between we have many crises. For example in 1992, we had the Mexican crisis, in 1998 we had the Asian crisis, in 2001 we had dot com bubble crisis, and so forth. The difference between all the crises is the degree of the sovereignity. For some, it is restricted to some countries and some of it is regional. The only noticeable characteristic is that a crisis now occurs more often. Previously every 12 years, and then every 10 years. Now it is happening more often because the global economy is so integrated. So, if you look back and you see this pattern, this is what is going to happen.

The buck-passing account of values offers an explanation of the close relation of values and reasons for action: of why it is that the question whether something that is of value provides reasons is not ”open.” Being of value simply is, its defenders claim, a property that something has in virtue of its having other reason-providing properties. The generic idea of buck-passing is that the property of being good or being of value does not provide reasons. It is other properties that do. There are, however, at least three versions of the account which differ in their understanding of those “other properties.” The first two versions both assume that non-normative properties provide reasons, the difference being that the second allows that normative properties also provide reasons. Both run into difficulties, which I explain, in trying to defend the claim that non-normative properties provide reasons for action. The third version of the buck-passing account which explains being of value in terms of more specific evaluative properties that are reason-providing remains unpersuasive as well. Once we understand the relation between general and specific properties as a difference in degree, there is no space for a reduction of the one kind of properties to the other. In section II I sketch an alternative account of the relation between reasons and values, which is based on a thesis that I call the Conceptual Link and the claim that values are not just co-extensive with reasons, but explain them.

In October 2017, the Supreme Court heard an appeal of a November 2016 ruling striking down Wisconsin’s State Assembly districts as a Republican gerrymander that illegally dilutes the weight of Democratic votes. We take the opportunity to revisit this litigation to evaluate three proposed methods of detecting gerrymanders: the “efficiency gap,” a count of Assembly districts carried by statewide candidates, and the difference between the district-level partisan median and mean. The first two measures figure either centrally or peripherally in the plaintiffs’ case in Wisconsin, while the third is the approach we favor. We expand on the analysis offered at trial by evaluating how these measures fare across a variety of elections in Wisconsin and with the aid of 10,000 alternative Assembly maps drawn by computer. The alternative maps provide the appropriate baseline with which to gauge the level of vote dilution in Wisconsin and distinguish between the effect of residential geography and the Legislature’s actions. The results show that Wisconsin’s Assembly map is a substantial gerrymander according the median–mean comparison across all elections, while the two tests relied upon by the plaintiffs provide mixed results. We examine the measurement qualities of each test and show that the efficiency gap and districts-carried count both capture elements beyond partisan bias. We find no similar ambiguity with the median–mean comparison and conclude that the plaintiffs’ claim that Wisconsin’s Assembly map systematically dilutes the weight of Democratic votes is correct.

Before the Law stands a doorkeeper. A man from the countryside comes up to the door and requests admittance to the Law. But the doorkeeper says that he can't grant him admittance now. The man thinks it over and then asks if he'll be allowed to enter later. “It's possible” says the doorkeeper, “but not now.” Since the gate to the Law stands open as always, and the doorkeeper steps aside, the man bends down to look through the gate into the interior. When the doorkeeper sees this, he laughs and says: “If you're so drawn to it, go ahead and try to enter, even though I've forbidden it. But bear this in mind: I'm powerful. And I'm only the lowest doorkeeper. From hall to hall, however, stand doorkeepers each more powerful than the one before. The mere sight of the third is more than even I can bear.” The man from the country has not anticipated such difficulties; the Law should be accessible to anyone at any time, he thinks, but as he now examines the doorkeeper in his fur coat more closely, his large, sharply pointed nose, his long, thin, blank tartar's beard, he decides he would prefer to wait until he receives permission to enter. And the doorkeeper gives him a stool and lets him sit down at the side of the door. He sits there for days and years. He asks time and again to be admitted and wearies the doorkeeper with his entreaties. The doorkeeper often conducts brief interrogations, inquiring about his home and many other matters, but he asks such questions indifferently, as great men do, and in the end he always tells him he still can't admit him. The man, who has equipped himself well for the journey, uses everything he has, no matter how valuable, to bribe the doorkeeper. And the doorkeeper accepts everything, but as he does so he says: “I'm taking this just so you won't think you've neglected something.” Over the many years, the man observes the doorkeeper almost incessantly. He forgets the other doorkeepers and this first one seems to him the only obstacle to his admittance to the Law. He curses his unhappy fate, loudly during the first years, later, as he grows older, merely grumbling to himself. He turns childish, and since he has come to know even the fleas in the doorkeeper's collar over his years of study, he asks the fleas too to help him change the doorkeeper's mind. Finally his eyes grow dim and he no longer knows whether it's really getting darker around him or if his eyes are merely deceiving him. And yet in the darkness he now sees a radiance that streams forth inextinguishably from the door of the Law. He doesn't have much longer to live now. Before he dies, everything he has experienced over the years coalesces in his mind into a single question he has never asked the doorkeeper. He motions to him, since he can no longer straighten his stiffening body. The doorkeeper hat to bend down to him, for the difference in size between them has altered greatly to the man's disadvantage. “What do you want to know now,” asks the doorkeeper, “you're insatiable.” “Everyone strives to reach the Law,” says the man, “how does it happen, then, that in all these years no one but me has requested admittance.” The doorkeeper sees that the man in nearing his end, and in order to reach his failing hearing, he roars at him: “No one else could gain admittance here, because this entrance was meant solely for you. I'm going to go and shut it now.”

For only eight decades (from 1921 to 2002), the population of Vojvodina got older for even ten years, which represents a great problem for the future of the population in this region. In the world, the average age of the population at the beginning of the 21st century is 27,6 years, showing that it is younger than the population in Vojvodina was at the beginning of the third decade of the 20th century. However, all population in Vojvodina does not get old at the same speed. Observing specific ethnic groups, the authors of this paper established differences related to the average age. There is a conclusion that the youngest population is the one which also has greater birthrates, and that is the case with the Goranci and the Roma. In addition to birthrate, the average age is also influenced by the number of the population itself, so the greater average age appears in these ethnic groups which are less numerous. On the basis of the spread of some ethnic groups in Vojvodina, the paper also established the difference in the average age of the population related to some regional units.

Changes in parameters of Tetranychus urticae Koch population growth were investigated based on the life tables of females treated with acutely non-toxic concentrations of Clofentezine (200 mg/L) and flufenzine (100 mg/L) in preoviposition period. Over the initial four days of reproduction females treated with Clofentezine laid 14% and those treated with flufenzine 16% less eggs than untreated ones. Gross fertility was 14% lower in the female cohort treated with Clofentezine and 24% lower in the one treated with flufenzine, compared to the untreated cohort. In treatment with flufenzine, the difference between the number of eggs laid and gross fertility mostly resulted from a considerably high number of unhatched eggs 35% on the first day of reproduction, 18% on the second, 4% on the third and 3% on the fourth day. Net fertility was 24% lower in females treated with Clofentezine and 28% lower in those treated with flufenzine over the initial four days of reproduction, compared to control, which means that female mortality under treatment additionally decreased fertility. The decreased net fertility in the initial days of reproduction did not result in a statistically significant decrease in growth rates.

SummaryIn 4 collaborative trials, involving a varying number of hospital laboratories in the Stockholm area, the coagulation activity of different test materials was estimated with the one-stage prothrombin tests routinely used in the laboratories, viz. Normotest, Simplastin-A and Thrombotest. The test materials included different batches of a lyophilized reference plasma, deep-frozen specimens of diluted and undiluted normal plasmas, and fresh and deep-frozen specimens from patients on long-term oral anticoagulant therapy.Although a close relationship was found between different methods, Simplastin-A gave consistently lower values than Normotest, the difference being proportional to the estimated activity. The discrepancy was of about the same magnitude on all the test materials, and was probably due to a divergence between the manufacturers’ procedures used to set “normal percentage activity”, as well as to a varying ratio of measured activity to plasma concentration. The extent of discrepancy may vary with the batch-to-batch variation of thromboplastin reagents.The close agreement between results obtained on different test materials suggests that the investigated reference plasma could be used to calibrate the examined thromboplastin reagents, and to compare the degree of hypocoagulability estimated by the examined PIVKA-insensitive thromboplastin reagents.The assigned coagulation activity of different batches of the reference plasma agreed closely with experimentally obtained values. The stability of supplied batches was satisfactory as judged from the reproducibility of repeated measurements. The variability of test procedures was approximately the same on different test materials.

The article discusses the future of mobility in the light of energy resources. Fossil fuel will not be available for a long time - not to mention its growing environmental and political conflicts. In analysing the potential of biofuel it is argued that the high demands of modern mobility can hardly be fulfilled in the future. Furthermore, the change into using biofuel will probably lead to increasing conflicts between the fuel market and the food market, as well as to conflicts with regional agricultural networks in the third world. Petrol imperialism might be replaced by bio imperialism. Therefore, mobility on a solar base pursues a double strategy of raising efficiency on the one hand and strongly reducing mobility itself on the other.

The ʿUthmānic way of writing (al-rasm al-ʿUthmānī) is a science that specialises in the writing of Qur'anic words in accordance with a specific ‘pattern’. It follows the writing style of the Companions at the time of the third caliph, ʿUthmān b. ʿAffān, and was attributed to ʿUthmān on the basis that he was the one who ordered the collection and copying of the Qur'an into the actual muṣḥaf. This article aims to expound on the two fundamental functions of al-rasm al-ʿUthmānī: that of paying regard to the ‘correct’ pronunciation of the words in the muṣḥaf, and the pursuit of the preclusion of ambiguity which may arise in the mind of the reader and his auditor. There is a further practical aim for this study: to show the connection between modern orthography and the ʿUthmānic rasm in order that we, nowadays, are thereby able to overcome the problems faced by calligraphers and writers of the past in their different ages and cultures.

The reality of the difference in applying Islamic law in the context of marriage law legislation in modern Muslim countries is undeniable. Tunisia and Turkey, for example, have practiced Islamic law of liberal nuance. Unlike the case with Saudi Arabia and the United Arab Emirates that still use the application of Islamic law as it is in their fiqh books. In between these two currents many countries are trying to apply the law in their own countries by trying to bridge the urgent new needs and local wisdom. This is widely embraced by modern Muslim countries in general. This paper reviews typologically the heterogeneousness of family law legislation of modern Muslim countries while responding to modernization issues. Typical buildings seen from modern family law reforms can be classified into four types. The first type is progressive, pluralistic and extradoctrinal reform, such as in Turkey and Tunisia. The second type is adaptive, unified and intradoctrinal reform, as in Indonesia, Malaysia, Morocco, Algeria and Pakistan. The third type is adaptive, unified and intradoctrinal reform, represented by Iraq. While the fourth type is progressive, unifiied and extradoctrinal reform, which can be represented by Somalia and Algeria.
