Three paradigms in a single monetary circulation

The nature of money is simple and easy to understand, both what it is and what it was; it is the ＂law of gravity＂ we all understand. Many macroeconomic concepts and operations are based on money. Without it, they would be impossible to comprehend and, in fact, can only be understood by methodically tracking the circulation of money. There are three core paradigms of money and money circulation： the money multiplier, the velocity of circulation of money income and the money-income multiplier. In this paper, we try to demystify or decouple some of these circulatory mechanisms in order to establish, to the extent that is possible, a single comprehensive theory. A comprehensive theory or an approximation to such demands that the three economic operations corresponding to the above three paradigms form part of the same monetary macroeconomic phenomenon. To prove workable, it requires that the formulae arrived at being represented by a single mathematical expression. This paper shows that there is a conflict between, on one hand, the inevitable and persistent economic intuition that relates the three paradigms and, on the other, the mathematical formulae （and their components） that occasionally negate this.     

Combinatorics in the theory of utility

It used to be thought that the utility or pleasure that goods gave consumers depended on the whole on the nature of the goods and, particularly, on its quantity. This is half true, half false. The utility obtained from a set of goods depends mainly on how the goods are ordered and combined within the dynamic time sequence represented by consumption. In other words, it depends less on what the goods are and more on how the goods are positioned. Understanding this offers huge possibilities within the theory of utility--and thus of consumption--as it allows us to apply the arsenal of tools available to us in the mathematic speciality known as combinatorics, as applied to utility. If each combination of goods poses a utility, we can rank these combinations differently using ordinal criteria and real transitive preferences. From there we can establish a set of menus, from best to least poor, and, armed with this information, work out a theory of individual choice. This is in brief the purpose of this work.     

The impact of student-generated digital flashcards on student learning of constitutional law

This article describes, evaluates and reflects upon student creation of cloud-based digital flashcards as an authentic formative and summative assessment task designed for the deep learning of constitutional law. The usefulness of digital flashcards in online legal education is explored. The undergraduate law student participants in the study responded differently to the assessment task depending upon the constitutional law topic they were assigned, the perceived relevance of constructing digital flashcards to professional practice and how they reacted to this creative task. Building digital flashcards provides a potentially powerful authentic assessment task for the study of constitutional law provided it is designed to support semester long creation, validation and sharing of digital flashcards that students perceive as professionally relevant and educationally useful. Student recommendations for designing an assessment task involving the creation of digital flashcards are evaluated.     

Los Congresos Estatales y la Política Federal en México: state legislatures and federal policymaking in Mexico

The Mexican Constitution, in the Poder Legislativo, grants state legislatures the authority to introduce legislation (iniciativas de ley) in the federal congress. In this paper the authors examine this powerful mechanism through which the Mexican state legislatures can directly influence policymaking at the federal level. Using a new data set of state-led initiatives, this work: describes the frequency with which iniciativas are introduced; describes the substance, timing, and final disposition of these state-led initiatives; and explains which factors affect the probability of presenting a state-led initiative. The authors find that party competition and partisan divisions at the state and federal levels play a significant role in the use of iniciativas de los congresos estatales. The authors’ study of this peculiar authority granted to the Mexican states contributes to the rich discussion of the changing role of the states in the era of Mexico’s nuevo federalismo.     

On the Use of Criminal Law Notions in Determining State Responsibility for Genocide

On the face of it the 1948 Convention on Genocide appears tobe a treaty that on the one hand obliges contracting statesto criminalize and punish genocide in their domestic legal systemsand, on the other, arranges for interstate judicial cooperationfor the repression of genocide. The International Court of Justice(ICJ), in the Bosnia v. Serbia judgment, has instead held thatthe Convention, in addition to providing for the criminal liabilityof individuals, also imposes on contracting states as internationalsubjects a set of obligations (to refrain from engaging in genocide,to prevent and punish the crime, and also to refrain for allthose categories of conduct enumerated in Article III: conspiracy,incitement, attempt, complicity). This approach raises two questions:(i) is it warranted so to broaden states' responsibility? (ii)when applying such Article III categories to state responsibility,should an international court such as the ICJ that pronounceson interstate disputes rely upon criminal law categories toestablish whether a state incurs responsibility for conspiracy,complicity, and so on? Or should it instead forge autonomouslegal categories better suited to state responsibility? Theauthor sets forth doubts about whether it is appropriate totranspose criminal law categories to the corpus of internationallaw of state responsibility. In particular, his misgivings relateto the category of ‘state complicity in genocide’as set out by the Court: once the Court decided to transplantthis criminal law category to state responsibility, arguablyit should have relied upon the rigorous concept of complicity,as derived by international criminal courts from case law andthe relevant practice of states, rather than apply a notionthat finds no basis in international criminal law, in comparativecriminal law or in state practice.     

Y-STRs in forensic medicine: DNA analysis in semen samples of azoospermic individuals

ABSTRACT: The incidence of rape has increased, especially in metropolitan areas, such as the city of São Paulo. In Brazil, studies about it have shown that the majority of this type of crime is committed by the relatives and persons close to the victim. This has made the crime more difficult to be denounced, as only 10% of the cases are reported to competent police authorities. Usually, cytological exams are carried out in sex crime investigations. The difficulty in showing the presence of spermatozoa is frequent, but it does not exclude the presence of male DNA. The absence of spermatozoa in material collected from rape victims can be due to several factors, including the fact that the agressor suffers from azoospermia. This condition can be the result of a successful vasectomy. As the majority of DNA in the ejaculation sample is from spermatozoa, there is much less DNA to be analyzed. This study presents the application of Y‐STRs (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, and DYS393) in DNA analysis of sperm samples from 105 vasectomized men. The study demonstrated a great variation in DNA concentration. DNA extraction and amplification was possible in all sperm samples even in the absence of spermatozoa. The same profile was observed, for each individual, from DNA extracted from blood, pre‐ and postvasectomy semen samples. The use of markers specific for Y chromosome in sex crime cases, especially in the absence of spermatozoa, is very important, mainly because in most situations there is a small quantity of the agressor's DNA in the medium and a large quantity of the victim's DNA.     

Intentional mixed buccal cell reference sample in a paternity case

We report a case where an alleged father (AF) attempted to substitute someone else's saliva sample for his reference sample in a paternity analysis. Buccal cells were collected from the AF and the child, and DNA analysis was performed using an autosomal STR loci (Identifiler). The profile from the AF showed extra peaks in some loci, as well as a much higher "X" allele peak relative to the "Y" allele peak at the amelogenin locus. After conducting reanalysis by another technician with another set of positive and negative controls, it was concluded that the only source of the mixed profile was by intentional introduction by the AF, at the time of sampling, of some foreign human biological material, most likely saliva from a woman. Owing to the inconclusive results, when the AF was called back to the lab and the peculiar results were explained to him, he admitted that he had introduced into his mouth saliva from another person in an attempt to be excluded as the father of the child. Although tampering with DNA reference samples is not common, some individuals may attempt to contaminate or otherwise adulterate specimens before DNA tests. Personnel responsible for sampling should be aware of this possibility and should try to establish procedures to avoid the problem.
