Non-conventional database management systems are used to achieve a better performance when dealing with complex data. One fundamental concept of these systems is object identity (OID), because each object in the database has a unique identifier that is used to access and reference it in relationships to other objects. Two approaches can be used for the implementation of OIDs: physical or logical OIDs. In order to manage complex data, was proposed the Multimedia Data Manager Kernel (NuGeM) that uses a logical technique, named Indirect Mapping. This paper proposes an improvement to the technique used by NuGeM, whose original contribution is management of OIDs with a fewer number of disc accesses and less processing, thus reducing management time from the pages and eliminating the problem with exhaustion of OIDs. Also, the technique presented here can be applied to others OODBMSs. © 2011 IEEE.

Has the time come to put to bed the concept of a harm threshold when discussing the ethics of reproductive decision making and the legal limits that should be placed upon it? In this commentary, we defend the claim that there exist good moral reasons, despite the conclusions of the non-identity problem, based on the interests of those we might create, to refrain from bringing to birth individuals whose lives are often described in the philosophical literature as ‘less than worth living’.

As Justice Douglas wrote in Skinner v. Oklahoma, procreation is one of the “basic civil rights of man.” Along with marriage it is “fundamental to the very existence and survival of the race” and the state’s interference with it “threatens to have subtle, far-reaching and devastating effects.” And yet the U.S. and other countries regulate a wide range of reproductive activities such as forbidding anonymous sperm donation, funding abstinence education, criminalizing brother-sister incest, preventing the sale of sperm or eggs or surrogacy services, and forbidding single individuals from accessing reproductive technologies. In justifying these and other regulations of reproduction legislatures, courts, and commentators have relied (at least in part) on an idiom that I call Best Interests of the Resulting Child (BIRC) as a justification, which focuses on the best interests of the child who will (absent state intervention) result from these forms of reproduction. My goal in this Article and its companion paper Regulating Reproduction: the Problem with Best Interests, 96 Minn. L. Rev. 423 (2011), http://ssrn.com/abstract=1955292 is to reveal and delve into the secret ambition of best interests (sometimes called child welfare or child-protective) discourse in the regulation of reproduction. By discussing best interests in this context...

Embrapa is the Brazilian Agricultural Research Corporation. It coordinates the national agricultural research system in Brazil and has for mission to provide solutions for the sustainable development of Brazilian agribusiness through knowledge and technology transfer. As such, it is involved in the development of GM and non-GM soybean varieties to provide farmers with the best germplasm they want. Soybean in Brazil: The area devoted to soybean in Brazil has been multiplied by about 60 in the last 50 years, while in the same time average yield has increased by 150%. Currently about three fourth of Brazilian soybean production is coming from only four States (by order of importance, Mato Grosso, Paraná, Rio Grande do Sul and Goías). In last years, the adoption of GM soybean by Brazilian farmers has still increased significantly, as it went from 62% of all soy cultivated area during the 2008/09 cropping season to 81% in 2010/11. However, there is an important variation across regions, since some States are still free of GM planting (e.g. Rondonia in the North, representing 1% of national soy production) and other are virtually integrally using GM soybean seeds (e.g. Rio Grande do Sul, 17% of national soy production). The most important States in terms of non-GM soybean production are Mato Grosso...

Immigrants from the West Indies and other nations challenge the simple United States dichotomy of blacks versus whites. Many apparently black Caribbean immigrants proclaim that they did not know they were “black” until they arrived in the U.S. They seek to maintain their national identity and resist identity and solidarity with Black Americans. In response, many Black Americans respond that the immigrants are simply being naive, that U.S. society demands simple racial identity. Regardless of one's self-identity and personal history, in the U.S., if you look black, you are black, was their thinking. ^ This study examines the contemporary struggle of identity and solidarity among and between Black Americans and Jamaicans living in South Florida (Broward and Miami-Dade counties). Even though the primary focus of this study is to examine the relationship between Black Americans and Jamaicans, other West Indian nationals will be addressed more generally. The primary research problem of this study is to determine why the existence of common ancestry and physical traits are insufficient for an assumption of ethnic solidarity between Black Americans and Jamaicans. ^ In examining this problem, I felt that depth rather than breadth would provide insight into the current state of polarization between Black Americans and Jamaicans. To this end...

## ‣ Non-domination and the Accommodation of Minority Social Practice

This thesis develops an account of non-domination as a principle of legitimacy that ought to govern both inter-group and intra-group relations in multicultural states. It applies this principle to the question of how political institutions should respond to claims for the accommodation of controversial minority practices, using the example of the polygamous community in Bountiful, British Columbia. In developing this account, the thesis engages with three bodies of theoretical literature – of multiculturalism, of political legitimacy, and of autonomy. In the dominant normative theories of multiculturalism, answers are centered on what the limits of toleration are, what it means to recognize a collective identity, or what group rights can be claimed and how group rights are balanced with individual rights. While not rejecting the importance of these issues in a pluralistic state, my approach de-centers them by subsuming them under the broader problem of what makes a political authority morally legitimate vis-à-vis particular collective - as well as abstract individual - subjects. I argue that the most promising response to this problem lies with the concept of non-domination, conceived as a foundational principle of political legitimacy for multicultural states. This principle both demands and checks a democratic method for determining specific forms of accommodation. In some cases the advancement of non-domination between groups conflicts with the advancement of non-domination within groups. In political theory this question is often taken up by feminist scholars concerned with the ‘paradox of multicultural vulnerability’ and...

## ‣ A narrativização de uma experiência feminina como instrumento de construção da identidade mestiça: análise semiótica de Borderlands/La Frontera de Gloria Anzaldúa; The narrativization of a female experience as a tool for construction of the mestizo identity: a semiotic analysis on Gloria Anzaldúa's Borderlands / La Frontera

This study aims at discussing the complex constitution of an identity formed in the southwest border of the United States of America with Mexico, based on the Gloria Anzaldúa‟s narrative in her book Borderlands/La Frontera: the new mestiza. Anzaldúa is a chicana born in the State of Texas in a border city with Mexico. In this region there are at the same place cultural forces that face each other, ending in psychological and social conflicts of order in the citizens, the chicanos. The non-harmonious meeting of White, Mexican and Indigenous cultures increases linguistics, racial and gender problems, which can be seen from Anzaldúa‟s voice. In order to analyze this narrative, we made use of the French Semiotics methods of Greimas (1993; 1973; 2008) that are named Generative Course of Meaning, among others theorists who shared the same ideas (BARROS, 1990a, 1990b, 2001; FIORIN, 2001; FONTANILLE, 2007; et al). The theoretical choice of the analysis is justified by the understanding that this theory appropriately fit the narrative analysis, because it contains tools to reveal its structure; also because we believe that the French Semiotics theory has a broader range and can approach the Meaning and the discussions that appear in the book. During the analysis...

This Article, lying at the intersection of law and bioethics, examines whether it is wrongful to use assisted reproductive technology to intentionally create disabled children and whether legal liability should attach to such acts. In particular, this Article considers the way these issues are intertwined with what philosophers have called the Non-Identity Problem, the idea that so long as a resulting child will have a life worth living the child cannot be harmed by being brought into existence, because even an impoverished life is better than not existing at all. In her Article in this symposium (http://ssrn.com/abstract=1295426), Kirstin Smolensky suggests that the Non-Identity Problem should cause us to extinguish tort liability in cases where disabled children are created by preembryo selection but not if it were done through (a still hypothetical technology enabling) the genetic manipulation of a pre-embryo to induce a disability. In this Article I critically examine this claim in two ways. First, I suggest some problems with her arguments for drawing a distinction (for Non-Identity Problem and hence legal liability purposes) between the two methods of creating disabled children. Second, I examine whether legal liability should be barred even for cases where the Non-Identity Problem applies. I set out several approaches drawn from the bioethics literature that suggest that the parents have acted wrongfully by creating disabled children notwithstanding the Non-Identity Problem. I then offer some tentative views about whether any of these approaches is a valid basis for legal liability...

Attempts were made to produce lesions in. animals by the injection of material obtained from the vesicles and involved skin of nine cases of herpes zoster. All the cases, with the exception of one (Case II), were characteristic cases of idiopathic herpes zoster and the question of their being cases of so called zosteriform herpes or symptomatic herpes zoster can hardly be raised. As regards Case II, if this case occurred alone, there might be some doubt as to its nature on account of the mildness of the symptoms and the small area of skin involvement. Taken in connection with Cases III and IV, however, which occurred in the same ward and in patients who were quite closely in contact with Patient II, it seems fairly reasonable to assume that they were all of the same character. Cases of herpes zoster have been extremely rare in this hospital and the occurrence of three cases in the same ward within a very short period of time suggests very strongly a transference of infection from one case to the other. That Case II was not one of herpes simplex also seems fairly certain from the negative results obtained by inoculation of rabbits' eyes with vesicle material. In making the animal experiments we employed various methods which were suggested largely by the technique used by previous observers...

This dissertation provides a defense of the normative intuition known as the Procreation Asymmetry, according to which there is a strong moral reason not to create a life that will foreseeably not be worth living, but there is no moral reason to create a life just because it would foreseeably be worth living. Chapter 1 investigates how to reconcile the Procreation Asymmetry with our intuitions about another recalcitrant problem case in population ethics: Derek Parfit's Non-Identity Problem. I show that what has prevented philosophers from developing a theory that gives a satisfactory account of both these problems is their tacit commitment to a teleological conception of well-being, as something to be promoted'. Replacing this picture with one according to which our reasons to confer well-being on people are conditional on their existence allows me to do better. It also enables us to understand some of the deep structural parallels between seemingly disparate normative phenomena such as procreating and promising. Chapter 2 attempts to connect my defense of the Procreation Asymmetry to corresponding evaluative claims about the goodness of the outcomes produced by procreative decisions. I propose a view, the biconditional buck-passing view of outcome betterness'...

A recent model for property testing of probability distributions enables tremendous savings in the sample complexity of testing algorithms, by allowing them to condition the sampling on subsets of the domain. In particular, Canonne, Ron, and Servedio showed that, in this setting, testing identity of an unknown distribution $D$ (i.e., whether $D=D^*$ for an explicitly known $D^*$) can be done with a constant number of samples, independent of the support size $n$ -- in contrast to the required $\sqrt{n}$ in the standard sampling model. However, it was unclear whether the same held for the case of testing equivalence, where both distributions are unknown. Indeed, while Canonne, Ron, and Servedio established a $\mathrm{poly}\log(n)$-query upper bound for equivalence testing, very recently brought down to $\tilde O(\log\log n)$ by Falahatgar et al., whether a dependence on the domain size $n$ is necessary was still open, and explicitly posed by Fischer at the Bertinoro Workshop on Sublinear Algorithms. In this work, we answer the question in the positive, showing that any testing algorithm for equivalence must make $\Omega(\sqrt{\log\log n})$ queries in the conditional sampling model. Interestingly, this demonstrates an intrinsic qualitative gap between identity and equivalence testing...

We define a problem "exact non-identity check": Given a classical description of a quantum circuit with an ancilla system, determine whether it is strictly equivalent to the identity or not. We show that this problem is NQP-complete. In a sense of the strict equivalence condition, this problem is different from a QMA-complete problem, non-identity check defined by D. Janzing etc. As corollaries, it is derived that exact equivalence check is also NQP-complete and that it is hard to minimize quantum resources of a given quantum gate array without changing an implemented unitary operation.; Comment: 10 pages, 3 figures

## ‣ Non-Identity Check Remains QMA-Complete for Short Circuits

The Non-Identity Check problem asks whether a given a quantum circuit is far away from the identity or not. It is well known that this problem is QMA-Complete \cite{JWB05}. In this note, it is shown that the Non-Identity Check problem remains QMA-Complete for circuits of short depth. Specifically, we prove that for constant depth quantum circuit in which each gate is given to at least $\Omega(\log n)$ bits of precision, the Non-Identity Check problem is QMA-Complete. It also follows that the hardness of the problem remains for polylogarithmic depth circuit consisting of only gates from any universal gate set and for logarithmic depth circuit using some specific universal gate set.; Comment: 8 pages

In a series of papers \cite{BRV1}, \cite{BRV2}, \cite{BRV3} we introduced full quivers and pseudo-quivers of representations of algebras, and used them as tools in describing PI-varieties of algebras. In this paper we apply them to obtain a complete proof of Belov's solution of Specht's problem for affine algebras over an arbitrary Noetherian ring. The inductive step relies on a theorem that enables one to find a "$\bar q$-characteristic coefficient-absorbing polynomial in each T-ideal $\Gamma$," i.e., a non-identity of the representable algebra $A$ arising from $\Gamma$, whose ideal of evaluations in $A$ is closed under multiplication by $\bar q$-powers of the characteristic coefficients of matrices corresponding to the generators of $A$, where $\bar q$ is a suitably large power of the order of the base field. The passage to an arbitrary Noetherian base ring $C$ involves localizing at finitely many elements a kind of $C$, and reducing to the field case by a local-global principle.; Comment: 44 pages, submitted

In this paper we present a deterministic polynomial time algorithm for testing if a symbolic matrix in {\emph non-commuting} variables over $\mathbb{Q}$ is invertible or not. The analogous question for commuting variables is the celebrated polynomial identity testing (PIT) for symbolic determinants. In contrast to the commutative case, which has an efficient probabilistic algorithm, the best previous algorithm for the non-commutative setting required exponential time [IQS15] (whether or not randomization is allowed). The algorithm efficiently solves the "word problem" for the free skew field, and the identity testing problem for arithmetic formulae with division over non-commuting variables, two problems which had only exponential-time algorithms prior to this work. The main (and simple) technical contribution of this paper is an analysis of an existing algorithm due to Gurvits which solved the same problem in some special cases. We also extend the algorithm to compute the (non-commutative) rank of a symbolic matrix, yielding a factor 2 approximation on the commutative rank. Symbolic matrices in non-commuting variables, and the related structural and algorithmic questions, have a remarkable number of diverse origins and motivations. They arise independently in (commutative) invariant theory and representation theory...

Sexual minority youths (SMY) face challenges in consolidating their sexual identity because of heterosexism. The role of homophobic bullying and coping strategies in the formation of sexual identity has been explored within a convenient sample of 262 sexual minority youths. Six dimensions of sexual identity formation have been tested, independent variables being: homophobic bullying, coping strategies (avoidance and problem-solving), age, gender, migration trajectory, residency, sexual attraction and time elapsed since the realization of the sexual identity difference. Homophobic bullying was associated with a lower score of sexual identity affirmation and higher scores of identity concealment, internalized homo/bi-phobia, acceptance concern, identity uncertainty and process difficulty. Problem-solving coping strategies were associated with acceptance concerns. Avoidance coping strategies were associated with higher scores of acceptance concern and process difficulty in accepting non-heterosexual identity. Results confirm the importance of homo/bi-phobia prevention in order to help SMY in sexual identity consolidation.; Cette étude examine l’impact de l’intimidation homophobe et des stratégies d’adaptation sur 6 dimensions de l’intégration de l’orientation sexuelle (OS) à partir d’un échantillon de 262 jeunes LGBT. Un modèle de régression linéaire a été réalisé pour chaque dimension...
