title: “De Indio a Campesino: la Construcción de Categorías Jurídicas en Contextos de Cambio Político e Ideológico en el Perú Republicano hasta el Último Militarismo”
Creators: name: Cuadros Sánchez, Hans Enrique
Publisher: name: forum historiae iuris
Year: 2018

description: El artículo versa sobre los discursos jurídicos y cambios legislativos respecto a la condición jurídica del “indio” en las etapas más resaltantes de la etapa republicana. El análisis inicia en los años previos para luego analizar con mayor detenimiento los procesos histórico-jurídicos de la etapa republicana hasta el gobierno militar de Juan Velasco Alvarado. Esta revisión historiográfica nos permitirá conocer la mentalidad jurídica que existía en los grupos dominantes de la República y cómo desde ella legislaban para asuntos que concernían a las poblaciones consideradas históricamente como indígenas. Finalmente, a través de este trabajo, quiero poner énfasis en el aspecto comunicacional y lingüístico que era vital para la consideración jurídica del “indio”, y cómo este aspecto ha sido invisibilizado en el ámbito jurídico por los grupos dominantes en el Perú y sus relaciones de poder.

description: La pandemia Covid-19 ha comportato conseguenze e trasformazioni prefigurando scenari inediti sul piano economico, sociale e personale, determinando anche nel campo della ricerca l’urgenza di esplorarne le ricadute. Il volume dà quindi conto delle indagini svolte e in corso, sin dai primi giorni del lockdown, dai docenti e dai collaboratori del Dipartimento di Scienze della Formazione dell’Università Roma Tre, toccando i temi più diversi: dalla didattica a distanza, all’università e nei diversi ordini di scuola, al futuro dei servizi di orientamento, dal lavoro socio-educativo nelle varie tipologie di servizi all’impatto della pandemia sulle comunità, dalle narrazioni ai linguaggi artistici a contrasto di quest’emergenza non solo sanitaria. Si sono così esplorate le diverse educazioni possibili, riassegnando centralità ai processi formativi e al benessere delle persone, provando a tratteggiare nuovi paradigmi e prospettive.
description: Il saggio presenta una ricerca realizzata nel periodo marzo-giugno 2020 con l’obiettivo è sostenere gli insegnanti, in servizio su posto comune e su posto di sostegno, per consentire loro di svolgere le attività didattiche resesi indispensabili nella prima emergenza sanitaria dovuta al Covid-19. La metodologia è la ricerca-formazione che ha previsto una modalità di formazione degli insegnanti in cui è stato presentato un repertorio di learning object finalizzato a favorire nella didattica a distanza la partecipazione e l’apprendimento degli allievi con disabilità insieme ai compagni di classe.
Counterterms in Gravity in the Light-Front Formulation and a D=2 Conformal-like Symmetry in Gravity

description: In this paper we discuss gravity in the light-front formulation (light-cone gauge) and show how possible counterterms arise. We find that Poincare invariance is not enough to find the three-point counterterms uniquely. Higher-spin fields can intrude and mimic three-point higher derivative gravity terms. To select the correct term we have to use the remaining reparametrization invariance that exists after the gauge choice. We finally sketch how the corresponding programme for N=8 Supergravity should work.

title: Etnónimos, “comunidades nativas” y otras categorías problemáticas del Estado en contextos de diversidad cultural: El caso de la Amazonía peruana
Creators: name: Espinosa, Oscar
Publisher: name: forum historiae iuris
Year: 2019

description: In countries with a high cultural and ethnic diversity, a rigid understanding and application of the regular legal categories employed by the state need to be revised, otherwise, they could generate unwanted social conflicts. This paper explores some cases of social conflict that have appeared in the relationship between the Peruvian state and the indigenous peoples of the Amazon region. The use of certain legal categories are discussed, such as the “native community”, the classification system and database for indigenous peoples, the use of official ethnonyms, the process of linguistic standardization, and the system for the registration of names and personal identities. In all of these cases, the way in which the state and its experts establish these legal categories tend to create social conflicts with the indigenous peoples, and eventually may end up undermining their rights, the same ones that the state pretends to uphold and defend.
The quest for companions to post-common envelope binaries IV: The 2:1 mean-motion resonance of the planets orbiting NN Serpentis

description: We present 69 new mid-eclipse times of the young post-common envelope binary (PCEB) NN Ser, which was previously suggested to possess two circumbinary planets. We have interpreted the observed eclipse-time variations in terms of the light-travel time effect caused by two planets, exhaustively covering the multi-dimensional parameter space by fits in the two binary and ten orbital parameters. We supplemented the fits by stability calculations for all models with an acceptable chi-square. An island of secularly stable 2:1 resonant solutions exists, which coincides with the global chi-square minimum. Our best-fit stable solution yields current orbital periods P_o = 15.47 yr and P_i = 7.65 yr and eccentricities e_o = 0.14 and e_i = 0.22 for the outer (o) and inner (i) planets, respectively. The companions qualify as giant planets, with masses of 7.0 M_Jup and 1.7 M_Jup for the case of orbits coplanar with that of the binary. The two-planet model that starts from the present system parameters has a lifetime greater than 10^8 yr, which significantly exceeds the age of NN Ser of 10^6 yr as a PCEB. The resonance is characterized by libration of the resonant variable Theta_1 and circulation of omega_i-omega_o, the difference between the arguments of periapse of the two planets. No stable non-resonant solutions were found, and the possibility of a 5:2 resonance suggested previously by us is now excluded at the 99.3% confidence level.

description: We investigate the contributions of quantum fields to black hole entropy by using a cutoff scale at which the theory is described with a Wilsonian effective action. For both free and interacting fields, the total black hole entropy can be partitioned into a contribution derived from the gravitational effective action and a contribution from quantum fluctuations below the cutoff scale. In general the latter includes a quantum contribution to the Noether charge. We analyze whether it is appropriate to identify the rest with horizon entanglement entropy, and find several complications for this interpretation, which are especially problematic for interacting fields.
description: 30 pages; v2, matches published version at PRD. Two references added, minor changes including additional remarks on the distinction between Euclidean and Lorentzian momentum cutoffs, on the degree of nonlocality in the effective action, and on the possibility that only the total entropy has an entanglement interpretation
A REVIEW OF THE TRANSACTIONAL PARENT-CHILD RELATIONSHIP BETWEEN PARENTAL ACADEMIC EXPECTATIONS AND ACADEMIC ACHIEVEMENT
Creators: name: Muro, Melissa Lares
Publisher: name: Zenodo
Year: 2022
Subjects: parental academic expectations

transactional model

description: This literature review interprets existing findings from the past two decades that examine the relationship between parental academic expectations and academic achievement using a transactional framework. The transactional model of development suggests that children engage in interactions across different contexts and that both children and their context shape the interaction between expectations and achievement. Unlike other models of development that view parents as the influencer of their children’s behaviors, the transactional model highlights how both parents and children influence the interaction process. Research on these variables has predominantly focused on the unidirectional parent-child relationship, with parental expectations predicting academic achievement, and has paid little attention to the transactional parent child-relationship. To interpret findings using a transactional theory framework, I review studies that examine the relationship between expectations and achievement. This review also discusses the available research that has directly examined the transactional relationship between the variables and reports evidence of their transactional relationship. Findings summarized in this review provide support that the relationship between parental expectations and academic achievement is transactional. Furthermore, although most studies have treated parental expectations as a static variable, this review provides evidence that expectations change over time. Because of the dynamic nature of the relationship between expectations and achievement, transactional theory suggests that academic achievement predicts changes in expectations over time. This review supports the need for continued studies that examine the transactional relationship between the variables over time with a diverse sample of children and their families.

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: This Letter reports a measurement of the cross section for producing pairs of central prompt isolated photons in proton-antiproton collisions at a total energy of 1.96 TeV using data corresponding to 9.5/fb integrated luminosity collected with the CDF II detector at the Fermilab Tevatron. The measured differential cross section is compared to three calculations derived from the theory of strong interactions. These include a prediction based on a leading order matrix element calculation merged with parton shower, a next-to-leading order, and a next-to-next-to-leading order calculation. The first and last calculations reproduce most aspects of the data, thus showing the importance of higher-order contributions for understanding the theory of strong interaction and improving measurements of the Higgs boson and searches for new phenomena in diphoton final states.

Constructing Limited Scale-Free Topologies Over Peer-to-Peer Networks

description: Overlay network topology together with peer/data organization and search algorithm are the crucial components of unstructured peer-to-peer (P2P) networks as they directly affect the efficiency of search on such networks. Scale-free (powerlaw) overlay network topologies are among structures that offer high performance for these networks. A key problem for these topologies is the existence of hubs, nodes with high connectivity. Yet, the peers in a typical unstructured P2P network may not be willing or able to cope with such high connectivity and its associated load. Therefore, some hard cutoffs are often imposed on the number of edges that each peer can have, restricting feasible overlays to limited or truncated scale-free networks. In this paper, we analyze the growth of such limited scale-free networks and propose two different algorithms for constructing perfect scale-free overlay network topologies at each instance of such growth. Our algorithms allow the user to define the desired scalefree exponent (gamma). They also induce low communication overhead when network grows from one size to another. Using extensive simulations, we demonstrate that these algorithms indeed generate perfect scale free networks (at each step of network growth) that provide better search efficiency in various search algorithms than the networks generated by the existing solutions.

description: Collinear and non-collinear spin structures of wurtzite phase CoO often appearing in nano-sized samples are investigated using first-principles density functional theory calculations. We examined the total energy of several different spin configurations, electronic structure and the effective magnetic coupling strengths. It is shown that the AF3-type antiferromagnetic ordering is energetically most stable among possible collinear configurations. Further, we found that a novel spiral spin order can be stabilized by including the relativistic spin-orbit coupling and the non-collinearity of spin direction. Our result suggests that a non-collinear spin ground state can be observed in the transition-metal-oxide nanostructures which adds an interesting new aspect to the nano-magnetism study.

description: How different cultures evaluate a person? Is an important person in one culture is also important in the other culture? We address these questions via ranking of multilingual Wikipedia articles. With three ranking algorithms based on network structure of Wikipedia, we assign ranking to all articles in 9 multilingual editions of Wikipedia and investigate general ranking structure of PageRank, CheiRank and 2DRank. In particular, we focus on articles related to persons, identify top 30 persons for each rank among different editions and analyze distinctions of their distributions over activity fields such as politics, art, science, religion, sport for each edition. We find that local heroes are dominant but also global heroes exist and create an effective network representing entanglement of cultures. The Google matrix analysis of network of cultures shows signs of the Zipf law distribution. This approach allows to examine diversity and shared characteristics of knowledge organization between cultures. The developed computational, data driven approach highlights cultural interconnections in a new perspective.

description: Using the density matrix renormalization group, we investigate the $S=1/2$ Heisenberg model on the honeycomb lattice with first- ($J_1$) and second-neighbor ($J_2$) interactions. We are able to study long open cylinders with widths up to 12 lattice spacings. For $J_2/J_1$ near 0.3, we find an apparently paramagnetic phase, bordered by an antiferromagnetic phase for $J_2\lesssim 0.26$ and by a valence bond crystal for $J_2\gtrsim 0.36$. The longest correlation length that we find in this intermediate phase is for plaquette valence bond (PVB) order. This correlation length grows strongly with cylinder circumference, indicating either quantum criticality or weak PVB order.

description: The in-medium physics of heavy quarkonium is an ideal proving ground for our ability to connect knowledge about the fundamental laws of physics to phenomenological predictions. One possible route to take is to attempt a description of heavy quark bound states at finite temperature through a Schroedinger equation with an instantaneous potential. Here we review recent progress in devising a comprehensive approach to define such a potential from first principles QCD and extract its, in general complex, values from non-perturbative lattice QCD simulations. Based on the theory of open quantum systems we will show how to interpret the role of the imaginary part in terms of spatial decoherence by introducing the concept of a stochastic potential. Shortcomings as well as possible paths for improvement are discussed.

Optimal Control And Design Of Power Systems Using Lyapunovs Direct Method
Creators: name: Vyas, Rajendra
Publisher: name: London South Bank University
Year: 1981

description: The complexity and time-varying nature of large power systems mashes the design of controllers for the synchronous generators extremely difficult. Various sophisticated control theories (e.g. Linear quadratic regulato1, domain separation, modal control) have been applied to linearised mathematically models of these ay ebene. In all these cases the design is carried out for rated machine power at a conditionally stable operating point. If changes in machine operating point, machine parameters or system configuration occur then the design performance will be ‘de-rated'. Adaptive control provides an alternative design approach to this problem, where the controller has a variable structure which enables iit to compensz'.e for variations in the controlled system. This approach is applicable to small (5%) disturbance condition only because during large disturbances, system parameters may vary too quickly to be compensated. In this latter case other design techniques may be applied. It is possible to use a small digital computer to switch from one algorithm to another to implement the required control. The particular approach used in this thesis (referred to as model reference-adaptive control) employs Lyapunov function based on the error generated by model and plant states to design the controller. This method ensures the stable behavior (in the sense of Lyapunov) of the controller

Our main result is to present all multiplications and involutions on a given $C^*$-algebra $\mathcal{A}$ under which $\mathcal{A}$ is still a $C^*$-algebra whereas we keep the norm unchanged. For each invertible element $a\in\mathcal{A}$ we also introduce an involution and a multiplication making $\mathcal{A}$ into a $C^*$-algebra in which $a$ becomes a positive element. Further, we give a necessary and sufficient condition for that the center of a unital $C^*$-algebra $\mathcal{A}$ is trivial.

description: An exact analytical solution of the ground state problem of the isotropic classical Heisenberg model on the Shastry-Sutherland lattice in external magnetic field $H$ is found for arbitrary ratio of diagonal to edge exchange constants $J_2/J_1$. The phase diagram of this model in the ($J_2/J_1, H/J_1$) plane is presented. It includes spin-flop, spin-flip and umbrella phases. The magnetization curves are found to be linear until saturation. It is shown numerically that the inclusion of the easy-axis anisotropy into the model leads to the appearance of the 1/3 magnetization plateau, corresponding to the collinear up-up-down spin structure. This explains the appearance of the 1/3 magnetization plateau in rare earth tetraborides RB$_4$. In particular, magnetization curve of the compound HoB$_4$ is explained.

Could some special coupled modes be effectively applied for the LHC complex? Apparently, the answer is positive: use of the circular modes in the injectors with their transformation into planar modes in the LHC allows both the space charge and beam-beam luminosity limitations to be significantly reduced, if not practically eliminated.

description: Vengono qui presentati i primi risultati di uni studio esplorativo volto a indagare le caratteristiche dell’esperienza della didattica a distanza nel periodo dell’emergenza sanitaria da Covid-19. L’indagine ha comportato la somministrazione di un Questionario online articolato in domande chiuse e domande aperte a 324 docenti e 731 studenti universitari. I dati ottenuti grazie all’analisi del contenuto relativamente alle risposte fornite alle domande aperte hanno evidenziato una generalizzata difficoltà relazionale legata alla riduzione del contatto e dell’interazione. Sebbene si intravedano alcuni vantaggi di tipo logistico e talvolta anche di tipo organizzativo, restano evidenti le problematiche relative alla scarsa possibilità di ricevere un feedback dallo studente e di svolgere una efficace valutazione dell’apprendimento conseguito, oltre alla fatica legata al carico di lavoro per il docente e alla difficoltà di mantenere a lungo l’attenzione per lo studente. In sintesi, la sola didattica online comporta spesso il rischio di ridurre la qualità del rapporto educativo in modo consistente. Si sottolinea quindi l’importanza di orientarsi verso una didattica integrata, in presenza e a distanza, per promuovere efficacemente i processi formativi.

description: ILO’s Convention 169 on indigenous peoples, which enshrines the right to prior consultation, has been in force since 1995 in Peru. In spite of that, the State has only begun its implementation 16 years later, in 2011. This was done through the enactment of a special law that provides for substantial legal and institutional changes, but it also raised many expectations regarding the recognition of indigenous rights and cultural justice. The first issue that arose was, obviously, that of determining who was the legal subject in favor of whom a right was going to be granted; in other words, who was going to be an “Indian”. The cases we studied evidence that top mining bureaucrats rewrite Andean legal history and anthropology to foster mining investment at all costs, including the negation of indigenous identity and the cultural distinctiveness of peasant and native communities concerned.

Creators: name: Deardorff, Max
Publisher: name: forum historiae iuris
Year: 2018

description: The objective of this article is to analyze the construction of certain juridical categories (cristiano nuevo, mudéjar, morisco, and cristiano viejo de moros) used to refer to individuals from the convert community in Granada (the former Nasrid kingdom) in the sixteenth century. In order to illustrate the evolution of these terms, I analyze not only legislation, but also petitions for privileges by members of the convert community, such as appeals for the right to bear arms and applications for the right to reside in Granada after the War of the Alpujarras (1568-1570). For decades, the historiography has generally taken for granted that all descendants of Muslims living in Granada after 1501 were, in legal terms, moriscos. This assumption was accompanied by another, namely that all members of this group were equally subject to specific subsets of legislation that subjected them to a separate tax regime, limited their access to certain professions, determined where they could and could not live, and affected their obligations to receive catechesis in their parish churches. Nevertheless, a detailed analysis of the Granada case demonstrates that the situation was, in fact, much more nuanced. Until the decade of the 1560s, real legislation took for granted that most descendants of the kingdom’s Muslims were New Christians (cristianos nuevos or nuevos convertidos), giving them limited access to certain professional positions, but in legal terms making them no different than converts from other faith traditions. After the War of the Alpujarras (1568-1570), however, the Crown began to employ the term morisco, a pejorative expression that had slowly come into popular use, but heretofore had remained without legal definition. Despite the prejudice reflected in the Crown’s appropriation of the term, the Crown did not intend it to be applied to all descendants of the kingdom’s Muslims. On the contrary, an analysis of legal decisions made by the Royal Tribunal of the Three Judges—in the period after 1570—illustrates that in repeated instances, royal judges denied that the term morisco was the accurate one to apply to certain such individuals.

description: In ecology, prey switching refers to a predator's adaptive change of habitat or diet in response to prey abundance. In this paper, we study piecewise-smooth models of predator-prey interactions with a linear trade-off in a predator's prey preference. We consider optimally foraging predators and derive a model for a 1 predator-2 prey interaction with a tilted switching manifold between the two sides of discontinuous vector fields. We show that the 1 predator-2 prey system undergoes a novel adding-sliding-like (center to two-part periodic orbit; "C2PO") bifurcation in which the prey ratio transitions from constant to time-dependent. Further away from the bifurcation point, the period of the oscillating prey ratio period doubles, suggesting a possible cascade to chaos. We compare our model predictions with data and demonstrate that we successfully capture the periodicity in the ratio between the predator's preferred and alternative prey types in data on freshwater plankton. Our study suggests that it is useful to investigate prey ratio as a possible indicator of how population dynamics can be influenced by ecosystem diversity.
CMB dipole asymmetry from a fast roll phase

description: The observed CMB (cosmic microwave background) dipole asymmetry cannot be explained by a single field model of inflation - it inevitably requires more than one field where one of the fields is responsible for amplifying the super-Hubble fluctuations beyond the pivot scale. Furthermore the current constraints on $f_NL$ and $tau_NL$ require that such an amplification cannot produce large non-Gaussianity. In this paper we propose a model to explain this dipole asymmetry from a spectator field, which is responsible for generating all the curvature perturbations, but has a temporary fast roll phase before the Hubble exit of the pivot scale. The current data prefers spectator scenario because it leaves no isocurvature perturbations. The spectator model will also satisfy the well-known constraints arising from quasars, and the quadrupole and octupole of the CMB.

description: La ricerca propone un’indagine esplorativa finalizzata a rilevare l’incidenza che la didattica universitaria a distanza ha avuto durante il lockdown sull’utilizzo dell’audiovisivo da parte degli studenti. L’indagine, condotta attraverso la somministrazione di un questionario ad un campione di studentesse e studenti del Dipartimento di Scienze della Formazione dell’Università Roma Tre, con un’età compresa tra i 20 e i 46 anni, mira in particolare a rilevare da un lato, se, come e in che misura sono cambiate le abitudini di consumo di prodotti audiovisivi da parte degli studenti impegnati nella didattica a distanza durante il periodo di confinamento e, dall’altro, l’impatto dell’utilizzo dell’audiovisivo nella didattica, in termini di facilitazione dei processi di apprendimento e di motivazione allo studio.
description: La pandemia Covid-19 ha comportato conseguenze e trasformazioni prefigurando scenari inediti sul piano economico, sociale e personale, determinando anche nel campo della ricerca l’urgenza di esplorarne le ricadute. Il volume dà quindi conto delle indagini svolte e in corso, sin dai primi giorni del lockdown, dai docenti e dai collaboratori del Dipartimento di Scienze della Formazione dell’Università Roma Tre, toccando i temi più diversi: dalla didattica a distanza, all’università e nei diversi ordini di scuola, al futuro dei servizi di orientamento, dal lavoro socio-educativo nelle varie tipologie di servizi all’impatto della pandemia sulle comunità, dalle narrazioni ai linguaggi artistici a contrasto di quest’emergenza non solo sanitaria. Si sono così esplorate le diverse educazioni possibili, riassegnando centralità ai processi formativi e al benessere delle persone, provando a tratteggiare nuovi paradigmi e prospettive.
A search for prompt lepton-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

description: We present a search for a light (mass < 2 GeV) boson predicted by Hidden Valley supersymmetric models that decays into a final state consisting of collimated muons or electrons, denoted "lepton-jets". The analysis uses 5fb-1 of sqrt(s) = 7 TeV proton--proton collision data recorded by the ATLAS detector at the Large Hadron Collider to search for the following signatures: single lepton-jets with at least four muons; pairs of lepton-jets, each with two or more muons; and pairs of lepton-jets with two or more electrons. This study finds no statistically significant deviation from the Standard Model prediction and places 95% confidence-level exclusion limits on the production cross section times branching ratio of light bosons for several parameter sets of a Hidden Valley model.

Creators: name: Liu, Dan
Publisher: name: figshare
Year: 2022
Subjects: Genomics

description: Castanea mollissima Blume is a nut tree belonging to Fagaceae and is widely distributed in Asia, America and Europe. C. mollissima is an important genetic source for the improvement of edible chestnut varieties and occupies an important position in the origin and evolution of chestnut plants. In this study, the mitochondrial genome (mitogenome) of C. mollissima was assembled and annotated, showing a polycyclic structure with two circular molecules of 363,232 bp and 24,806 bp. This genome had 35 unique protein-coding genes, including 24 unique mitochondrial core genes and 11 non-core genes, 19 tRNA genes and 3 rRNA genes. This work reported the first mitogenome of C. mollissima, which serves as a reference genome for economically important plants of the genus Castanea and also provides much-desired information for molecular breeding.

description: We compute, in the framework of the fluid/gravity correspondence, the transport coefficients of a relativistic fluid affected by chiral and gauge-gravitational anomalies, including external electromagnetic fields. The computation is performed at first and second order in the hydrodynamical expansion. We use a 5-dim holographic model with pure gauge and mixed gauge-gravitational Chern-Simons terms in the action. We reproduce at first order previous results on the anomaly induced current of a magnetic field and a vortex in a relativistic fluid, and compute at second order the anomalous and non anomalous transport coefficients by using a Weyl covariant formalism. We find a dissipative and anomalous correction to the chiral magnetic conductivity due to the time dependence of the magnetic field. We also find a new contribution from the mixed gauge-gravitational anomaly to the shear waves dispersion relation. The role played by the chiral and gravitational anomalies in other transport coefficients is discussed.
